In this study, we report a 26-year-old female case of Niemann–Pick disease type C in association with Fuchs heterochromic iridocyclitis who was admitted with the complaint of ocular pain and redness following trauma. She had mild inflammatory signs and also vertical ocular motility limitations.

Adams–Oliver syndrome (AOS) is a rare congenital disorder with unknown etiology commonly presented with aplasia cutis and terminal limb defects. Central nervous and cardiopulmonary systems may also be affected. It is commonly inherited as an autosomal dominant disorder but autosomal recessive and sporadic cases have also been reported. Here, we present a 10-year-old boy with extensive aplasia cutis congenita and limb anomalies as well as mild pachygyria and focal acrania in neuroimaging. No other internal organ involvement was obvious in this patient. Family history was negative for this syndrome. AOS is a multisystem disorder, and so it is crucial to investigate for internal organ involvements.

Background: The aim of this study was investigation of the effects of Nigella sativa (NS) seeds on hypothyroid pregnant rats and their progenies. Materials and Methods: Hypothyroidism was induced by propylthiouracil (PTU) 0.03% in drinking water. Female rats were divided into seven groups: control, PTU, PTU-NS (100, 200, and 400 mg/kg), and NS (100 and 400 mg/kg). All treatments were done 20 days before mating and during pregnancy. The weight of rat dams and progenies, number of progenies and serum T4, estradiol and prolactin (PRL) levels in rat dams were measured for all groups. Results: Serum T4 in all PTU-NS groups before mating was significantly increased versus PTU group. Body weight of rat dams before mating in all groups of PTU-NS was increased versus PTU group by P < 0.001, P < 0.05, and P < 0.001, respectively and in NS 100 and NS 400 was increased versus control group (P < 0.001). The number of offspring was significantly decreased in PTU and PTU-NS versus control group. The weight of progenies in NS 400 was higher than control group (P < 0.001) and was increased in PTU-NS 200 and PTU-NS 400 versus PTU group by P < 0.001 and P < 0.05, respectively. Serum PRL level in rat dams in control, PTU, and PTU-NS groups were not statistically different between groups but significantly increased in NS 400 group when compared to control group. Estradiol levels were not significantly different in rat dams at 5 days after delivery. Conclusion: These results demonstrated that feeding of rat dams with NS extract before mating has positive protective effects on progenies. These effects may be due to antioxidant properties of NS in reducing oxidative stress and thyroid damages induced by PTU.

Background: Cerebral venous thrombosis (CVT) is an uncommon cerebrovascular disease with a wide spectrum of symptoms and severity. This study analyzes the factors influencing the incidence of papilledema in patients with cerebral venous thrombosis. Materials and Methods: In this research 65 patients with CVT were examined between 2011 and 2013, and the patients were followed up one, three, six, and twelve months after the initial diagnosis. They were separated into two groups according to presence or absence of papilledema. We analyzed the frequency of symptoms and risk factors of cerebral venous thrombosis and the intensity of papilledema as time passed, as also the frequency of the involved sinus, in two groups of patients with and without papilledema. Results: This study showed that the most common symptom was headache, with a frequency of 92.3% and the least common symptoms were ataxia and quadriparesis, with a frequency of 1.5%. The most common risk factors were high waist circumference (WC) and oral contraceptive pil (OCP) use, and also in patients with papilledema the intensity is reduced as time passes. Conclusion: This investigation showed that there was no significant relation between the frequency of risk factors and symptoms and intensity of papilledema as time passed in the two groups. The results showed that the most common sinuses involved in patients with papilledema were sagittal and lateral sinuses, which included 66.7%, and the most common sinus involved in patients without papilledema, which was the lateral sinus that included 40%.

Background: Ovarian angiogenesis (OA) remains in lifetime and normal ovarian function depends to this continual remodeling of a complex vascular system. Endometrial thickness (ET) is one of the strongest predictors of successful implantation and pregnancy. Appropriate OA effects on ET by facilitating of ovarian hormone delivery. Materials and Methods: Thirty adult female mice and twenty adult male mice were purchased. The female mice were divided into three groups: (1) control group without any intervention (n = 10), (2) gonadotropin group: receiving human menopausal gonadotropin (HMG) and human chorionic gonadotropin (n = 10), and (3) gonadotropin and sildenafil citrate (SC) group: receiving HMG and SC administration (n = 10). After mating, animals were deeply anesthetized, and the ovary and uterus was rapidly removed for histology and immunohistochemistry process. Results: Four days after ovarian induction, all three layers of the uterus with specified thickness can be clearly seen. The heights of endometrial epithelial cells in gonadotropin group were not significantly different than those in control group. In gonadotropin and SC group, heights of the cells were significantly (P < 0.05) shorter than control and gonadotropin groups. ETs in all groups were not significantly deferent from each other (P > 0.05 each). Our results of immunohistochemistry survey for ovarian CD31 demonstrated that administrated SC increased OA but not significantly (P > 0.05 each). Conclusion: It may finally conclude that administration of SC does not cause notable alterations in OA and ET; although for realistic decision about the SC effects on aforementioned parameters, more molecular investigations and longer drug consumption period are necessary.

Background: One of the most lethal cancers is hepatocellular carcinoma (HCC). Genistein (GE) is a choice compound for treatment of certain types of cancer. Phytoestrogens are plant derivatives that bear a structural similarity to 17-β estradiol (E2) and act in a similar manner. They are a group of lipophillic plant compounds with tumorigenic and antitumorigenic effects. E2 has stimulatory and inhibitory effects on cancer cell lines. This study was designed to investigate the antiproliferative and apoptotic effects of GE and E2 on the HCC HepG2 cell line. Materials and Methods: HepG2 cells were cultured and treated with various concentrations of GE and E2 and then 3-[4, 5-dimethyl-2-thiazolyl]-2, 5-diphenyl-2H-tetrazolium bromideand flow cytometry assay were performed to determine cell viability and apoptosis. Results: GE and E2 induced apoptosis and inhibited cell growth significantly. Reduction of cell viability by 50% required 20 μM E2 for E2-treatment groups and 20 μMGE for GE-treatment groups. The percentage of the GE-treated apoptotic cells was reduced by about 35%, 42%, and 47% (P < 0.001) and that of E2-treated groups 34%, 39%, and 42% (P < 0.001) after 24, 48, and 72 h, respectively. Conclusions: Our experimental work clearly demonstrated that GE and E2 exhibited significant antiproliferative and apoptotic effects on human HCC HepG2 cells.

Background: Orexins are excitatory neuropeptides which stimulate the central regulatory pathways. Orexins increase the penicillin-induced epileptic activity in rats. Orexin-A increases in different types of seizures and its elevated level is the characteristic feature in the epileptic children during polysomnography. Recently, the orexin receptor blockage has been reported to increase seizure threshold in mice; however, effect of the selective orexin-A receptor antagonist (SB-334867) on 4-aminopyridine (4-AP)-induced seizures has not been investigated. Materials and Methods: We used the intraperitoneal injection of 4-AP to induce seizure in male rats. Under urethane anesthesia, SB-334867 (50 and 100 nmol) was injected stereotaxically into the ventral hippocampal commissure. Using video recording, the effects of SB-334867 on electroencephalogram and tonic–clonic convulsions were compared to those that received diazepam or dimethyl sulfoxide (DMSO). Results: SB-334867 significantly decreased the duration of spike trains compared to DMSO-treated rats (P < 0.001) and reduced the duration of convulsive seizures (P < 0.05). Seizure onset was increased significantly by SB-334867, 50 nmol, compared to DMSO (P < 0.05) and diazepam (P < 0.01) treated rats. Conclusion: Antagonism of orexin-A receptor by a low-dose SB-334867 showed protective effects in 4-AP-induced seizure-like activities in anesthetized rats.

Background: In radiation therapy, computed tomography (CT) simulation is used for treatment planning to define the location of tumor. Magnetic resonance imaging (MRI)-CT image fusion leads to more efficient tumor contouring. This work tried to identify the practical issues for the combination of CT and MRI images in real clinical cases. The effect of various factors is evaluated on image fusion quality. Materials and Methods: In this study, the data of thirty patients with brain tumors were used for image fusion. The effect of several parameters on possibility and quality of image fusion was evaluated. These parameters include angles of the patient's head on the bed, slices thickness, slice gap, and height of the patient's head. Results: According to the results, the first dominating factor on quality of image fusion was the difference slice gap between CT and MRI images (cor = 0.86, P < 0.005) and second factor was the angle between CT and MRI slice in the sagittal plane (cor = 0.75, P < 0.005). In 20% of patients, this angle was more than 28° and image fusion was not efficient. In 17% of patients, difference slice gap in CT and MRI was >4 cm and image fusion quality was <25%. Conclusion: The most important problem in image fusion is that MRI images are taken without regard to their use in treatment planning. In general, parameters related to the patient position during MRI imaging should be chosen to be consistent with CT images of the patient in terms of location and angle.

Background: This study was carried out to compare mucociliary function (MCF) of nasal cavity before and after septorhinoplasty surgery by saccharin test. Materials and Methods: This study was carried out on 70 patients who needed septorhinoplasty surgery in Kashani and Alzahra Hospital during 2013–2014 to measure MCF. Saccharin test was performed on the patients before surgery and on three more intervals 1 day, 1 week, and on month after ward and the readings were recorded. Saccharin test is performed by placing saccharin granules on the anterior part of inferior turbinate and the time the patient feels the sweet taste is recorded the normal range is below 30 min. Results: Mean of test for each time interval was obtained and comparison of measurements was made reading were mean of saccharin test before surgery (7.74 ± 1.65 min) the day after surgery (7.75 ± 1.7 min), on week after surgery (15.04 ± 3.4), and 1 month after surgery (8.49 ± 2.08 min). The readings before surgery did not have statistically significant difference with the readings 1 day after surgery P = 0.99, but comparison of test results at other time intervals were significant (P < 0.001). A relative increase in saccharin test time was seen in a period of 1 month after surgery the rise was more noticeable in the 1^st week compared to 1 month after surgery. Conclusion: This study in the period after septorhinoplasty surgery MCF undergoes slight impairment that gradually progresses to normal values during 1 month after surgery.

Background: Coronary artery disease (CAD) is multifactorial disease, in which thrombotic occlusion and calcification occur usually. New strategies have been made for diagnosis and treatment of CAD, such as transradial catheterization. Hemostasis could be done in two approaches: traditional and patent. Our aim is to find the best approach with lowest complication. Materials and Methods: In a comparative study, 120 patients were recruited and divided randomly into two subgroups, including traditional group (60 patients; 24 females, 36 males; mean age: 64.35 ± 10.56 years) and patent group (60 patients; 28 females, 32 males; mean age: 60.15 ± 8.92 years). All demographic data including age, gender, body mass index, and CAD-related risk factors (smoking, diabetes, hypertension) and technical data including the number of catheters, procedure duration, and hemostatic compression time and clinical outcomes (radial artery occlusion [RAO], hematoma, bleeding) were collected. Data were analyzed by SPSS version 16. Results: Our findings revealed that the incidence of RAO was significantly lower in patent groups compared with traditional group (P = 0.041). Furthermore, the difference incidence of RAO was higher in early occlusion compare with late one (P = 0.041). Moreover, there were significant relationship between some factors in patients of traditional group with occlusion (gender [P = 0.038], age [P = 0.031], diabetes mellitus [P = 0.043], hemostatic compression time [P = 0.036]) as well as in patent group (age [P = 0.009], hypertension [P = 0.035]). Conclusion: Our findings showed that RAO, especially type early is significantly lower in patent method compared classic method; and patent hemostasis is the safest method and good alternative for classical method.

Background: Obsessive-compulsive disorder (OCD) is a chronic disorder that strongly affects one's life and social, emotional, and occupational functioning. Due to the effect of religious beliefs on phenomenology of OCD, in this paper, we assess the effectiveness of religious cognitive behavioral therapy (CBT) within 3 and 6 months follow-up. Materials and Methods: This study is a clinical trial with follow-ups which last 2 months consisting eight sessions of 1.5 h of religious CBT. The research is conducted in a group of 40, with pre- and post-test after 3 and 6 months. Used Yale-Brown OCD symptom scale, before, the end, after 3 months and after 6 months of intervention. Treatment is carried out by a psychiatrist and a clergyman through religious CBT. The trial is held in OCD clinic affiliated with Noor Hospital. Results are analyzed by ANOVA repeated measure with SPSS18. Results: The results showed a considerable decrease in OCD symptoms which remained almost persistent after 3 and 6 months (F = 3/54. P = 0/024). It also shows that religious CBT can leave substantial effect on OCD symptoms; permanency of this intervention after 3 and 6 months is noticeable (P < 0/001). In Conclusion this therapy could be helpful for OCD patients with religious content. Conclusion: RCBT have a positive effect on people with religious obsessive -compulsive.

Background: Chronic stress adversely influences brain functions while crocin, as an effective component of saffron, exhibits positive effects on memory processes. This study investigated the effects of different doses of crocin on the improvement of learning and memory as well as corticosterone (CORT) levels in the hippocampus and frontal cortex of rats subjected to chronic stress. Materials and Methods: Forty male rats were randomly allocated to five different groups (n = 8): Control, sham; stress (6 h/day for 21 days) groups, and two groups receiving daily intraperitoneal injections of one of two doses (30 and 60 mg/kg) of crocin accompanied by 21 days of restraint stress. Latency was evaluated as a brain function using the passive avoidance test before and one-day after a foot shock. CORT levels were measured in the homogenized hippocampus and frontal cortex. Results: Results revealed that chronic stress had a significantly (P < 0.01) negative effect on memory. Crocin (30 and 60 mg/kg), however, gave increase to significantly (P < 0.01 and P < 0.05; respectively) improved memory functions in the stressed rats. Furthermore, the CORT levels in the hippocampus and frontal cortex declined significantly (P < 0.05) in the stress group compared to the control. Only a crocin dose of 30 mg/kg was observed modulate significantly (P < 0.05) the CORT levels in the hippocampus and frontal cortex in the stressed group. Conclusions: It was found that the lower crocin dose (30 mg/kg) had more beneficial effects than its higher (60 mg/kg) dose on learning and memory under chronic stress conditions. Moreover, it was speculated that different doses of crocin act on different neurotransmitters and biochemical factors in the brain.

Background: Gene editing technology has created a revolution in the field of genome editing. The three of the most famous tools in gene editing technology are zinc finger nucleases (ZFNs), transcription activator-like effector nucleases, clustered regularly interspaced short palindromic repeats (CRISPR), and CRISPR-associated systems. As their predictable nature, it is necessary to assess their efficiency. There are some methods for this purpose, but most of them are time labor and complicated. Here, we introduce a new prokaryotic reporter system, which makes it possible to evaluate the efficiency of gene editing tools faster, cheaper, and simpler than previous methods. Materials and Methods: At first, the target sites of a custom ZFN, which is designed against a segment of ampicillin resistance gene, were cloned on both sides of green fluorescent protein (GFP) gene to construct pPRO-GFP. Then pPRO-GFP was transformed into Escherichia coli TOP10F' that contains pZFN (contains expression cassette of a ZFN against ampicillin resistant gene), or p15A-KanaR as a negative control. The transformed bacteria were cultured on three separate media that contained ampicillin, kanamycin, and ampicillin + kanamycin; then the resulted colonies were assessed by flow cytometry. Results: The results of flow cytometry showed a significant difference between the case (bacteria contain pZFN) and control (bacteria contain p15A, KanaR) in MFI (Mean Fluorescence Intensity) (P < 0.0001). Conclusion: According to ZFN efficiency, it can bind and cut the target sites, the bilateral cutting can affect the intensity of GFP fluorescence. Our flow cytometry results showed that this ZFN could reduce the intensity of GFP color and colony count of bacteria in media containing amp + kana versus control sample.

Background: The present study tries to compare the unintended outcomes of the Catania stent versus Xience stent in patients undergoing angioplasty. Materials and Methods: In a three month, follow-up, double-blinded, randomized controlled trial, 83 patients undergoing angioplasty, who met the inclusion criteria were entered into the study. After randomization 43 patients were treated with the Xience stent and 40 patients with the Catania stent. Stent-related outcomes such as Cardiac and Non-Cardiovascular Death, Myocardial Infarction (MI), Target Lesion Revascularization (TLR), Stent Thrombosis (ST), Coronary Artery Bypass Grafting (CABG), Peripheral vasculopathy, and Cerebral Vascular Accident (CVA) were compared between the groups. Results: There was no statistically significant difference in the incidence rate of complications and clinical outcomes between the two treatment groups (P > 0.05). The incidence of MI, TLR, CABG operation, peripheral vasculopathy, or CVA was not observed in any patient and there was no statistically difference in mortality (4.7% vs. 2.5%; P = 0.527) and stent thrombosis (2.3% vs. 2.5%; P = 0.735). Conclusion: All in all, the present study could not find the significant differences between the Catania stent and Xience stent in terms of clinical outcomes during the follow-up period.

Background: Breast cancer is among the most common cancers in the world. Ultrasound evaluations of breast have come into attention as an alternative route. Ultrasound features of benign lesions such as fibroadenoma can be overlapping with those in a malignant tumor. Here, we assessed the reports of breast ultrasound in patients with pathologic diagnosis of fibroadenoma. Materials and Methods: We conducted a cross-sectional study and enrolled female patients with confirmed histologic diagnosis of fibroadenoma. Ultrasound studies were performed on the participants to see which sonographic patterns are more frequent in such lesions. Results: In 92 patients with 40.4 ± 9.2 years of age, all participants were classified as stage 4 on Breast Imaging-Reporting and Data System scale. The mean ± standard deviation of size for the lesions was 167.4 ± 101.4 mm². Upper outer quadrants in the breasts had the most number of lesions. Almost lesions were round with only 2.2% were oval. When assessed for the margin definition, 57.8% were circumscribed. Noncircumscribed masses were reported in 21.7%. About 91.3% of cases were hypoechoic in the ultrasound evaluation. Lobulated masses were in 28.3% of the cases. 8.7% of the masses were spongy whereas 9.8% and 2.2% of them had calcification and heterogenic appearance, respectively. Conclusion: The most frequent features include a hypoechoic mass with a circumscribed border; however, complex presentations that overlap malignant masses are also detectable including noncircumscribed margin, lobulation, presence of a posterior shadow, heterogenicity, and micro calcification.

Background: This study aims to evaluate the effect of some factors, including birth weight, sex, age, waist circumference, family history of obesity, as well as some lifestyle factors as frequency of breakfast days and physical activity, on the body mass index among a nationally representative sample of Iranian children and adolescents by using bootstrapping regression. Materials and Methods: This study was conducted as the third survey of a school-based surveillance system (CASPIAN-III study). Total participants were 5570 school students, aged 10-18 years, selected by multistage random cluster sampling from urban and rural areas of 27 provinces of Iran. Multiple linear regressions was used to evaluate the effect of various factors on obesity, but in our data the assumptions of this model violated, and possible solutions were not appropriate, therefore the bootstrapping regression based on the observations and errors resampling approaches was used as an alternative. Results: The tests of significance showed that the effects of sex, age, waist circumference, family history obesity and frequency of breakfast days were clearly significant (P < 0.001). The effect of vigorous level of physical activity was significant in comparison to mild physical activity (P = 0.01). In comparison to low birth weight, medium and high birth weight had significant effect on obesity. Conclusions: Bootstrap method is preferable in linear regression because of some theoretical properties like having any distributional assumptions on the residuals and hence allows for inference even if the errors do not follow normal distribution or constant error variance.

Background: Acute pelvic inflammatory disease (PID) is a common reason for infertility. This study aimed to evaluate the frequency distribution of endometritis in women with unexplained infertility and comparison with frequency distribution of endometritis in anovulatory infertility to identify the importance of endometritis due to subacute PID evaluation in the case of infertility. Materials and Methods: This case–control study was done on 100 women with unexplained infertility and ovulatory infertility who referred to Shahid Beheshti clinic in 2013 in Isfahan, Iran. They were divided into two groups of unexplained infertility and anovulatory infertility. Endometrial samples were given from all the patients by Pipelle biopsy under sterile conditions, and then prepared samples were sent to the pathology laboratory to evaluate the existence of plasma cells by a pathologist to diagnose endometritis. Results: Frequency distribution of acute PID history among the patients in both groups showed a significant difference (P < 0.05). Prevalence of endometritis in unexplained infertility group was 34% and in anovulatory group was 21% (P < 0.05). Prevalence of vaginitis was 46% in unexplained group and 40% in anovulatory group (P < 0.05), and prevalence of PID was 4% in unexplained infertility group and 0% in anovulatory infertility group. Conclusion: The prevalence of endometritis and vaginitis was more in the unexplained infertility group rather than the anovulatory infertility group that may reveal the importance of endometritis evaluation in the cases of unexplained infertility.

Background: Renal involvement in systemic lupus erythematous is one of the most serious complications. The aim of this study was to compare the effects of treatment decisions based on clinical symptoms and renal biopsy on the outcome of patients with recurrent lupus nephritis. Materials and Methods: This descriptive study was conducted in 2012–13 in the Alzahra hospital on patients with lupus nephritis who had referred to the rheumatology clinic of this center due to lupus nephritis relapse. All lupus nephritis patients were diagnosed with renal biopsy and had gone into remission by treatment but due to the discontinuation of treatment and other causes had relapsed. The patients were divided randomly into two groups of 26, the first group was treated without renal biopsy and based on clinical and laboratory symptoms and the second group was re-biopsied through considering the ethical points. Then their relationship with laboratory findings (BUN, Cr, ANA, ds-DNA, C3, C4, CH50, U/A, cast, and proteinuria), treatment and recurrence outcome were compared between the two groups. Results: The mean of SLEDAI-2K index before initial treatment, after the first round of treatment and after the second round of treatment in single biopsy group and twice biopsy group is not significantly different (P = 0.27). Conclusions: Treatment decisions based on clinical and laboratory findings or re-biopsy of the kidney in patients who relapsed after initial treatment had no significant effect on the recovery of patients. Adoption of a treatment plan in patients with lupus nephritis is recommended based on clinical and laboratory finding and the discretion of the physician and if possible, kidney re-biopsy should be avoided.

Background: Since thin and high-quality flaps produce more satisfactory surgical outcomes, flaps created by mechanical microkeratomes are more economical as compared with femtosecond lasers, and no Iranian study has concentrated laser in situ keratomileusis (LASIK) flap peculiarities between Moria Sub-Bowman keratoplasty (SBK) microkeratomes and LDV femtoseconds, the present study compares and contrasts them. Materials and Methods: This cross-sectional study was done on all patients who underwent LASIK surgery 1-month before this study. Thirty eyes were divided into per group. Flaps in the first group and second group were created, respectively, using Moria SBK microkeratome and LDV femtosecond laser. The other stages of LASIK were done equally in both groups. One month after surgery, the thickness of flaps was measured by anterior segment optical coherence tomography in five regions of flaps. Corneal anterior density was calculated and recorded 1-month after surgery using pentacam and by employing optical densitometry in a distance in the limit range of 0–6 mm from cornea center. Densitometry measurements were obtained and expressed in standardized grayscale units (GSUs). Results: Postsurgery densitometry results reveal that anterior densities of cornea in limit range of 0–2 mm in groups of LDV femtosecond laser and Moria microkeratome are 21.35 ± 0.87 GSU and 22.85 ± 1.25 GSU, respectively. Accordingly, these two groups are significantly different in this regard (P < 0.001). Moreover, anterior densities of the cornea in the limit range of 2–6 mm in these groups are 19.66 ± 0.99 GSU and 20.73 ± 1.24 GSU, respectively. Accordingly, these two groups are significantly different in this regard (P = 0.04). There is a lower mean of flap thickness in the case of LDV femtosecond laser. Conclusion: Femtosecond laser method is greatly preferred as compared with Moria microkeratome because of greater homogeneity in flap thickness, smaller thickness, and lower density in optical zone.

Background: Attention deficit and hyperactivity disorder (ADHD) is a common psychological problem during childhood. This study aimed to evaluate multiple intelligences profiles of children with ADHD in comparison with non-ADHD. Materials and Methods: This cross-sectional descriptive analytical study was done on 50 children of 6–13 years old in two groups of with and without ADHD. Children with ADHD were referred to Clinics of Child and Adolescent Psychiatry, Isfahan University of Medical Sciences, in 2014. Samples were selected based on clinical interview (based on Diagnostic and Statistical Manual of Mental Disorders IV and parent–teacher strengths and difficulties questionnaire), which was done by psychiatrist and psychologist. Raven intelligence quotient (IQ) test was used, and the findings were compared to the results of multiple intelligences test. Data analysis was done using a multivariate analysis of covariance using SPSS20 software. Results: Comparing the profiles of multiple intelligence among two groups, there are more kinds of multiple intelligences in control group than ADHD group, a difference which has been more significant in logical, interpersonal, and intrapersonal intelligence (P < 0.05). There was no significant difference with the other kinds of multiple intelligences in two groups (P > 0.05). The IQ average score in the control group and ADHD group was 102.42 ± 16.26 and 96.72 ± 16.06, respectively, that reveals the negative effect of ADHD on IQ average value. There was an insignificance relationship between linguistic and naturalist intelligence (P > 0.05). However, in other kinds of multiple intelligences, direct and significant relationships were observed (P < 0.05). Conclusions: Since the levels of IQ (Raven test) and MI in control group were more significant than ADHD group, ADHD is likely to be associated with logical-mathematical, interpersonal, and intrapersonal profiles.

Background: Pseudomonas aeruginosa is a severe challenge for antimicrobial therapy, due to the chromosomal mutations or exhibition of intrinsic resistance to various antimicrobial agents such as most β-lactams. We undertook this study to evaluate the existence of SME, IMP, AIM, and VIM metallo-β-lactamases (MBL) encoding genes among P. aeruginosa strains isolated from Intensive Care Unit (ICU) patients in Al-Zahra Hospital in Isfahan, Iran. Materials and Methods: In a retrospective cross-sectional study that was conducted between March 2012 and April 2013, a total of 48 strains of P. aeruginosa were collected from clinical specimens of bedridden patients in ICU wards. Susceptibility test was performed by disc diffusion method. All of the meropenem-resistant strains were subjected to modified Hodge test for detection of carbapenemases. Multiplex polymerase chain reaction was performed for detection of blaVIM, blaIMP, blaAIM, and blaSME genes. Results: In disk diffusion method, imipenem and meropenem showed the most and colistin the least resistant antimicrobial agents against P. aeruginosa strains. Of the 48 isolates, 36 (75%) were multidrug resistant (MDR). Amplification of β-lactamase genes showed the presence of blaVIM genes in 7 (%14.6) strains and blaIMP genes in 15 (31.3%) strains. All of the isolates were negative for blaSME and blaAIM genes. We could not find any statistically significant difference among the presence of this gene and MDR positive, age, or source of the specimen. Conclusion: As patients with infections caused by MBL-producing bacteria are at an intensified risk of treatment failure, fast determination of these organisms is necessary. Our findings may provide useful insights in replace of the appropriate antibiotics and may also prevent MBLs mediated resistance problem.

Background: Vitamin D insufficiency is a globally widespread issue. Recent studies have reported a high prevalence of Vitamin D deficiency in Middle-East countries. Studies have shown negative effects of Vitamin D deficiency on endothelium and related diseases such as ischemic brain stroke. Here, we assessed Vitamin D status in patients with different types of ischemic brain stroke and control group. Materials and Methods: Seventy-five patients (49.3% small vessel, 50.7% large vessel) and 75 controls, matched for age (68.01 ± 10.94 vs. 67.64 ± 10.24) and sex (42 male and 33 female) were recruited. 25(OH) D levels were measured by Chemiluminescence immunoassay. 25(OH) D status was considered as severely, moderately, or mildly deficient and normal with 25(OH) D levels of less than 5, 5-10, 10-16, and >16 ng/ml, respectively. Results: Mean ± standard error concentration of 25(OH) D in cases and controls were 17.7 ± 1.5 and 26.9 ± 1.6 (P = 0.0001), respectively. Mild, moderate, and severe Vitamin D deficiency were observed in 10.8%, 32.4%, 8.1% vs. 34.3%, 31.5%, 9.5% of small vessel and large vessel group, respectively. 21.7% of the controls were Vitamin D deficient. Vitamin D deficiency was significantly associated with higher risk for ischemic stroke, (P = 0.000, OR = 7.17, 95% confidence interval: 3.36–15.29). 25(OH) D levels were significantly higher in control group comparing to small vessel (26.9 ± 1.6 vs. 20.59 ± 2.6 P < 0.05) and large vessel (26.9 ± 1.6 vs. 13.4 ± 1.3 P < 0.001) stroke patients. Small vessel group had significantly higher levels of Vitamin D than large vessel (P < 0.05). Conclusion: Vitamin D deficiency significantly increases the risk of ischemic stroke, favoring the types with the pathogenesis of large vessel strokes.

Background: Long-term anesthesia applied in some operations, especially in neurosurgical operations leads to unwanted complications. This study aimed to compare the effect of intraoperative labetalol and lidocaine injection on the rate of changes in postoperative blood pressure and heart beat in patients undergoing brain operation. Materials and Methods: This is a simple double-blind randomized clinical trial study conducted in Al-Zahra and Kashani Hospitals on 90 patients' candidate for craniotomy operation with the age range of 18–65 years, Glasgow Coma Scale (GCS) ≥13 before anesthesia, physical class of American Society of Anesthesiologists I, II, insensitivity to labetalol who were divided into two groups of 45 individuals in the random allocation method. To start anesthesia, fentanil 1.5 mg per 1 kg of body weight, midazolam 5 mg, propofol 2 mg/kg and then, atracurium 0.15 mg/kg and lidocaine 1.5 mg/kg were used. The rate of patients' bucking and blood pressure were checked at GCS time after operation and in patients' recovery in terms of 0, 5, 10, 20 and 30 min after arrival in the recovery room and 1 h later. Results: There was no significant difference in terms of hemodynamic parameters during the period of operation and recovery and at the time of extubation and during the study, no case of bradicardia, hypotension, tachycardia or hypertension was observed in the patients of both groups. Conclusion: Using labetalol in craniotomy surgery is helpful for two main reasons that are the proper control of intraoperative and postoperative blood pressure and prevention of postoperative reactions, especially cough and if there is no contraindication for using it, it is recommended.

Background: Angiogenesis which occurs mandatory in solid tumors, is a critical step in malignancy progression. Vascular endothelial growth factor (VEGF) is mainly responsible for angiogenesis process and facilitates the formation of new vessels. Distribution of monoclonal antibodies against VEGF or VEGF receptor (VEGFR) into the solid tumors is limited because of their huge dimensions. Moreover, many investigations have demonstrated the usefulness of immunotoxins to halt angiogenesis in solid tumors. Materials and Methods: We designed, expressed and evaluated the cytotoxicity of a novel nano-immunotoxin composed of VEGF splice variant containing 121 amino acids (VEGF121) and truncated the exotoxin A of Pseudomonas aeruginosa (PE38-KDEL). The fusion protein VEGF121-PE38 was successfully cloned and expressed in Escherichia coli, purified by Ni^{+ 2} affinity chromatography. The fusion protein was subsequently subjected to refolding using the reduced and oxidized glutathione. Results: The expression level of the fusion protein reached to 1 mg/ml. The VEGF121-PE38 immunotoxin showed a 59 KDa MW which had cytotoxic effect on HUVEC and 293/KDR cells as low and high expressing VEGFR2 cells, respectively. But the cytotoxicity on 293/KDR was 100 folds more than that of VEGFR2 low expressing cell HUVEC. Conclusion: The designed immunotoxin showed more selectivity for higher VEGFR2 expressing cells in vitro.

Background: Polymorphisms in Plasmodium falciparum merozoite surface protein-2 (msp-2) and associated parasite genetic diversity which varies between malaria-endemic regions remain a limitation in malaria vaccine development. Pro-inflammatory cytokines are important in immunity against malaria, understanding the influence of genetic diversity on cytokine response is important for effective vaccine design. Methods: P. falciparum isolates obtained from 300 Nigerians with uncomplicated falciparum malaria at Ijede General Hospital, Ijede (IJE), General Hospital Ajeromi, Ajeromi (AJE) and Saint Kizito Mission Hospital, Lekki, were genotyped by nested polymerase chain reaction of msp-2 block 3 while ELISA was used to determine the pro-inflammatory cytokine response to describe the genetic diversity of P. falciparum. Results: Eighteen alleles were observed for msp-2 loci. Of the 195 isolates, 61 (31.0%) had only FC27-type alleles, 38 (19.7%) had only 3D7-type alleles, and 49.3% had multiple parasite lines with both alleles. Band sizes were 275–625 bp for FC27 and 150–425 bp for 3D7. Four alleles were observed from LEK, 2 (375–425 bp) and 2 (275–325 bp) of FC27-and 3D7-types, respectively; 12 alleles from AJE, 9 (275–625 bp) and 3 (325–425 bp) of FC27-types and 3D7-types, respectively; while IJE had a total of 12 alleles, 9 (275–625 bp) and 3 (325–425 bp) of FC27-types and 3D7-types, respectively. Mean multiplicity of infection (MOI) was 1.54. Heterozygosity (H_E) ranged from 0.77 to 0.87 and was highest for IJE (0.87). Cytokine response was higher among <5 years and was significantly associated with MOI (P > 0.05) but with neither parasite density nor infection type. Conclusion: P. falciparum genetic diversity is extensive in Nigeria, protection via pro-inflammatory cytokines have little or no interplay with infection multiplicity.

Background: Limited spatial nasal cavity in children, make pediatric dacryocystorhinostomy (DCR) a difficult surgical procedure. We apply a limited approach to pediatric DCR and follow them for their consequences. Materials and Methods: An experimental study was done in pediatric DCR with limited approach (age < 14-year-old). After written consent, with general anesthesia, with nasal endoscopic surgery, lacrimal bone is exposed and extruded. In contrast with routine procedure, ascending process of maxillary sinus reserve; and marsupialization and wide exposure to lacrimal sac was done only by lacrimal bone defect; and cannulation preserve with temporary silicone tube. Results: Between 2006 and 2012, 16 pediatric DCR was done by a unique surgeon in 2 otorhinolaryngologic centers. Before surgery 14 (87.5%) had epiphora, 3 (18.8%) had eye discharge, and 3 (18.8%) had eye sticky eye. Two (12.5%) had history of facial trauma, and 10 (62.5%) had congenital nasolacrimal duct insufficiency. Five (31.3%) had history of dacryocystitis. Patients were followed for 17 ± 9 months. Silicone tube stayed for 4 ± 2.5 months. We could follow 7 patients and minimal improvement or need to revision surgery considered as technical failure. After surgery, 3 patients had no epiphora with complete improvement; 2 had very good improvement with confidence of the patients and parents; 2 cases had unsuccessful surgery in our patients, who needs to another surgery. One of them had several probing and surgery before our endoscopic DCR. Conclusions: Limited approach in endoscopic DCR of pediatrics can be done in noncomplicated patients, with minimal manipulation, more confidence, and acceptable results.

Background: In this study, we compare the level of two inflammatory markers, high sensitive C-reactive protein (hs-CRP) and procalcitonin (PCT), in pregnant women with mild and severe preeclampsia (PE) and women with normal pregnancy. Materials and Methods: In this case–control study, normal pregnant women and pregnant women with PE were enrolled. Pregnant women with diagnosed PE were selected as case group and classified into two groups with mild and severe PE. Serum samples for measurement of hs-CRP and PCT were obtained and compared in studied groups. Results: In this study, 50 normal pregnant women and 59 pregnant women with PE, 26 (44.1%) mild, and 33 (55.9%) severe were studied. Mean of hs-CRP and PCT was higher in pregnant women with PE than normal pregnant women (7.71 ± 6.19 vs. 5.44 ± 3.94, P = 0.02 for hs-CRP and 0.05 ± 0.03 vs. 0.04 ± 0.01, P = 0.001 for PCT). Area under curve for hs-CRP and PCT was 0.611 and 0.646, respectively. The optimal cut-off point for hs-CRP was 5.24 with a sensitivity of 62.7% and a specificity of 56%. The optimal cut-off point for PCT was 0.042 with a sensitivity of 71% and a specificity of 54%. Conclusion: The findings of this study indicated that higher level of hs-CRP and PCT in pregnant women with PE than those with normal pregnancy could potentially explain the exaggerated inflammation in PE. Regarding significantly increased level of hs-CRP in severe PE than mild PE, we could suggest that hs-CRP is more appropriate marker for investigating pregnant women with severe PE, and its clinical usefulness is superior to PCT in this regard.

Background: To determine the effects of knee taping in combination with exercise and medical treatment on functional outcome and pain of patients with knee osteoarthritis (OA). Materials and Methods: In a randomized single-blinded clinical trial, 36 patients with knee OA were randomly assigned to two study groups. Both groups received exercise and medical therapy for 6 weeks. In addition, the first group (20 patients) received taping in the first 3 weeks. Pain severity (assessed by visual analog scaling), weekly amount of analgesics consumption, timed get up and go test (TUG), and step tests were recorded at baseline, 3 and 6 weeks after the treatment and were further compared between two study groups. Results: There was no significant difference between two groups in pain severity score (P = 0.228), step test score (P = 0.771), TUG test score (P = 0.821) and weekly amount of analgesics consumption (P = 0.873) at baseline. After 3 weeks, weekly amount of analgesics consumption (P = 0.006), pain severity (P < 0.001) was significantly lower in taping group whereas step test score (P = 0.006) was significantly higher in the taping group. After 6 weeks, patients in taping group had significantly lower pain severity (P = 0.011) and higher step test score (P = 0.042). However, there was no significant difference in TUG test score (P = 0.443) and weekly amount of analgesics consumption (P = 0.270) between two groups. Conclusion: Therapeutic knee taping may be an effective method for short-term management of pain and disability in patients with knee OA.

Background: Angiogenesis plays a major role in endometrial receptivity and thickening of the endometrium immediately before implantation. The aim of the present work was to evaluate the antiangiogenic properties of epigallocatechin-3-gallate (EGCG) from green tea in angiogenesis of endometrium. Materials and Methods: In this study, forty adult female NMARI mice randomly divided into four groups. Control group received vehicle; human menopausal gonadotropin/human chorionic gonadotropin (HMG/HCG) group received 7.5 IU HMG intraperitoneal (IP) and 48 h later 7.5 IU HCG was injected (IP) for ovarian stimulation; HMG/HCG + EGCG group received HMG and HCG in the same manner as the previous group and also received 5 mg/kg EGCG at 0, 24, 48, and 72 h after injection of HMG; and the group EGCG received 5 mg/kg EGCG. A male mouse was kept with two female animals in the same cage for mating. Mice were dissected 96 h after administration of HMG (immediately before implantation) and tissue processing was carried out for the uterine specimens. CD31-positive cells were counted by use of histological and immunohistochemical methods. Results: Angiogenesis in EGCG-treated group was less than that of control and gonadotropin group (P < 0.05). The number of endothelial cells was counted by CD31 marker under a light microscope and showed significant differences between all groups (P < 0.05). Conclusion: EGCG significantly inhibited the angiogenesis in endometrium (in natural cycles) through antiangiogenic effects.

Background: A serious challenge to educate health staff for public health is to appear encouraging enough to persuade them for learning issues on this field and implementing new educational methods and innovative ways. Iran International Public Health Summer School (IPHS) made an effort to provide medical sciences students with a fortune to get familiar with and involved in public health. This study intended to evaluate the efficacy of this event. Materials and Methods: This cross-sectional study was performed in March–April 2015 by the help of an electronic self-administered questionnaire filled out by 49 Iranian participants 6 months after IPHS2014. The questionnaire assessed the main goals in seven main domains: Interest, activities, and general knowledge in the field of public health, general skills, educational methods, educational and executive schedules, and general satisfaction. Results: Average scores of all domains were >3 (the mean), and all were statistically significant. The highest average score belonged to educational methods (3.92) and the lowest was calculated for the item regarding participants' activities on public health (3.5). No significant difference was found between positive answers of individuals who were interested or active in public health prior to the event and those who had no background. Conclusions: We believe IPHS was a unique instance in Public Health Education in Iran. Considering the level of success of this program to reach its goals for both students' with or without any previous background on public health, it is recommended as a general model to be simulated in other developing countries.

Background: One of the most common orthopedic clinic visits involves direct and indirect knee trauma leading to rupture of anterior cruciate ligament (ACL). Endobutton and Rigidfix are most frequent treating methods that used by orthopedic surgeons. Thus the aim of this study was compare the clinical results of reconstructing arthroscopic ACL of the knee through two methods namely Rigidfix and Endobutton. Materials and Methods: In a clinical trial study, a total of 40 patients with rupture of ACL were selected and randomly divided into two groups. The groups were treated through fixation procedures either Endobutton or Rigidfix. Prior to surgery and then at least 2 years after surgery, the patients were under physical examination in terms of knee range of motion, knee stability, knee pain, ability to perform daily activities and exercises and compared between the two groups. Results: The knee range of motion in Endobutton and Rigidfix were 135.73 ± 2.63 and 129.87 ± 7.14° resprectively (P = 0.06). comparing two groups, during last month in Endobutton and Rigidfix the frequency of knee pain were 2.5 ± 1.4 and 3.4 ± 1.4 respectively (P = 0.08). Moreover, the pain intensity score were 2.9 ± 1.5 and 2.6 ± 1.1 (P = 0.49). But there was a significant difference observed in patients' satisfaction and ability to perform sports activities. Conclusions: The two fixation methods namely Endobutton and Rigidfix are not preferred over one another. But patients' satisfaction and ability to perform sports activities in Endobutton was better than the Rigidfix.

Background: Many previous studies showed that maternal forced exercise can reduce some central disorders in offsprings, but its clear mechanism remains unclear. In this study, the role of 5-HT₂ and D₂ receptors in neuroprotective effects of maternal forced exercise in offspring neurodevelopment and effect on some behaviors were evaluated. Materials and Methods: Forty-eight pregnant rats were trained by forced exercise, and some behavioral assays in their offspring were performed in the presence and absence of 5-HT₂ and D₂ receptor antagonists in various experimental groups. Results: Our data showed that maternal forced exercise caused increase in latency of pain perception in offsprings in hot plate test, writhing test (WT), and tail flick test. Furthermore, a decrease in intensity was shown by WT. On the other hand, treatment of mothers by forced exercise in combination with 5-HT₂ and D₂ receptor antagonists could inhibit these effects of forced exercise and cause disturbances in pain perception and intensity. Conclusion: Our data suggested that maternal forced exercise causes protective effects on offspring pain perception and intensity, and in this effect, 5-HT₂ and D₂ receptors are probably involved.

Background: In considering the importance of postoperative pain management and its consequences on its related secondary outcomes including nausea, vomiting, and operation-related complications, we aimed to compare the effectiveness of the three analgesic agents including ketamine, paracetamol, and magnesium sulfate for postoperative pain relief and associated consequences in this trial. Materials and Methods: In this double-blinded randomized control clinical trial, patients scheduled for elective lower extremity orthopedic surgery under general anesthesia were enrolled and randomized into four groups for receiving intravenous ketamine (0.25 mg/kg), paracetamol (15 mg/kg), magnesium sulfate (7.5 mg/kg), and placebo (normal saline), immediately after the induction of anesthesia. Postoperative pain scores, analgesic, and metoclopramide use, and frequency of vomiting and satisfaction score of studied patients in the four studied groups during the 6 h, 6–12 h, and 12–24 h after recovery were recorded and compared. Results: In this trial, thirty patients randomized in each studied groups. Mean of postoperative pain score was significantly lower in ketamine group than others during 24 h after recovery (P < 0.001). Mean of additive analgesic use was significantly lower in ketamine group during 12 h after recovery (P < 0.001), but it was not significantly different during 12–24 h after recovery (P = 0.12). Mean of vomiting frequency and metoclopramide use was not different between groups (P > 0.05). Excellent and good satisfaction score were significantly higher in ketamine group than other groups (P = 0.04). Conclusions: Ketamine has more superior effect for during recovery and postoperative pain controlling and analgesic use than paracetamol and magnesium sulfate.

Background: Nontuberculous mycobacteria (NTM) are a group of opportunistic pathogens and these are widely dispersed in water and soil resources. Identification of mycobacteria isolates by conventional methods including biochemical tests, growth rates, colony pigmentation, and presence of acid-fast bacilli is widely used, but these methods are time-consuming, labor-intensive, and may sometimes remain inconclusive. Materials and Methods: The DNA was extracted from NTM cultures using CTAB, Chelex, Chelex + Nonidet P-40, FTA^® Elute card, and boiling The quantity and quality of the DNA extracted via these methods were determined using UV-photometer at 260 and 280 nm, and polymerase chain reaction (PCR) amplification of the heat-shock protein 65 gene with serially diluted DNA samples. Results: The CTAB method showed more positive results at 1:10–1:100,000 at which the DNA amount was substantial. With the Chelex method of DNA extraction, PCR amplification was detected at 1:10 and 1:1000 dilutions. Conclusions: According to the electrophoresis results, the CTAB and Chelex DNA extraction methods were more successful in comparison with the others as regard producing suitable concentrations of DNA with the minimum use of PCR inhibitor.

Homocystinuria is the second most common treatable aminoacidopathy. Clinically, affected patients present with eye, skeleton, central nervous system, and most importantly, vascular system abnormalities. This autosomal recessive disorder leads to accumulation of homocysteine and its metabolites in the blood and urine. In this report, we present a case with clinical and biochemical findings of homocystinuria with stroke and a positive familial history of the disease in her brother. A 4-year-old girl was admitted to pediatric emergency ward because of acute onset of right hemiparesis and subsequent generalized tonic–clonic seizures. Cranial magnetic resonance imaging revealed acute infarct areas in the left cerebral hemisphere. Metabolic screening revealed elevated concentrations of serum homocysteine and methionine and a normal serum concentration of vitamin B12. These findings, along with a positive familial history led to the diagnosis of homocystinuria. In any child who presents with stroke, some rare condition such as homocystinuria should be considered in diagnosis.

Background: Nutritional support plays a major role in the management of critically ill patients. This study aimed to compare the nutritional quality of enteral nutrition solutions (noncommercial vs. commercial) and the amount of energy and nutrients delivered and required in patients receiving these solutions. Materials and Methods: This cross-sectional study was conducted among 270 enterally fed patients. Demographic and clinical data in addition to values of nutritional needs and intakes were collected. Moreover, enteral nutrition solutions were analyzed in a food laboratory. Results: There were 150 patients who fed noncommercial enteral nutrition solutions (NCENS) and 120 patients who fed commercial enteral nutrition solutions (CENSs). Although energy and nutrients contents in CENSs were more than in NCENSs, these differences regarding energy, protein, carbohydrates, phosphorus, and calcium were not statistically significant. The values of energy and macronutrients delivered in patients who fed CENSs were higher (P < 0.001). Energy, carbohydrate, and fat required in patients receiving CENSs were provided, but protein intake was less than the required amount. In patients who fed NCENSs, only the values of fat requirement and intake were not significantly different, but other nutrition delivered was less than required amounts (P < 0.001). CENSs provided the nutritional needs of higher numbers of patients (P < 0.001). In patients receiving CENSs, nutrient adequacy ratio and also mean adequacy ratio were significantly higher than the other group (P < 0.001). Conclusion: CENSs contain more energy and nutrients compared with NCENSs. They are more effective to meet the nutritional requirements of entirely fed patients.

Background: Coliform bacteria are used as indicator organisms for detecting fecal pollution in water. Traditional methods including microbial culture tests in lactose-containing media and enzyme-based tests for the detection of β-galactosidase; however, these methods are time-consuming and less specific. The aim of this study was to evaluate polymerase chain reaction (PCR) for detecting coliform. Materials and Methods: Totally, 100 of water samples from Isfahan drinking water source were collected. Coliform bacteria and Escherichia coli were detected in drinking water using LacZ and LamB genes in PCR method performed in comparison with biochemical tests for all samples. Results: Using phenotyping, 80 coliform isolates were found. The results of the biochemical tests illustrated 78.7% coliform bacteria and 21.2% E. coli. PCR results for LacZ and LamB genes were 67.5% and 17.5%, respectively. Conclusion: The PCR method was shown to be an effective, sensitive, and rapid method for detecting coliform and E. coli in drinking water from the Isfahan drinking water sources.

Background: Patients affected by gliomas have a poor prognosis. Astrocytoma is a subtype of glioma. Identification of biomarkers could be an effective way to an early diagnosis of tumor or to distinguish more aggressive tumors that need more intensive therapy. In this study, we investigated whether the expression of miR-362 was increased or decreased in patients with different grades of astrocytoma. Materials and Methods: miR-362 expression was compared in 25 patients with astrocytoma with that of 4 normal nonneoplastic brain tissues. Results: In all tumor tissues, the expression of miR-362 was significantly decreased relative to its expression in normal brain tissues. However, there was no significant difference between miR-362 expressions in high and low grades of astrocytoma. Conclusions: In conclusion, miR-362 showed a down-regulation pattern in astrocytoma tissues that was different from the pattern obtained from previously published microarray studies.

Background: Regarding to the complications of malnutrition in dialysis patients, using an easy and reliable method for evaluating of malnutrition is important in patients with the end-stage renal disease. Based on the effect of inflammatory factors in malnutrition, A new scale has been designed which is called malnutrition–inflammatory scale (MIS). We designed current study to assess the severity of malnutrition in peritoneal dialysis patients in Isfahan via MIS. Materials and Methods: In this cross-sectional MIS was used for evaluation of malnutrition. MIS includes 10 components: dry weight changes, dietary intake, functional capacity, comorbidity, muscle wasting and loss of subcutaneous fat as well as body mass index (BMI), serum albumin level and total iron binding capacity (TIBC). Each component has four levels of severity from 0 (normal) to 3 (severely abnormal). All analyses were performed using Statistical Package for Social Sciences version 20 (SPSS 20) and P < 0.05 were considered statistically significant. Results: Results showed no significant difference in MIS between male and female participants. Mean of minimum inhibitory concentration in this study was calculated about 4.1 (MIS <9) which means no or mild malnutrition. Significant correlation between MIS and weight (P < 0.001), BMI (P < 0.001), TIBC (P < 0.001), triglyseride (P = 0.04) and arm circumference (P < 0.001) was seen. Conclusion: We suggest That MIS is being used as a valuable tool for prevention of fatal outcomes in chronic dialysis patients.

Background: Emergence from anesthesia is associated with sympathetic stimulation, increase in pulse and blood pressure. There are different methods, but the most appropriate method should be selected regarding the differences in nationalities. This study aimed to compare the efficacy of morphine and labetalol in controlling blood pressure and pulse during emergence from anesthesia in brain tumors craniotomy. Materials and Methods: This study was conducted at Al-Zahra Hospital of Isfahan - Iran on 60 patients suffering from brain tumor candidated for craniotomy and randomly classified into two groups of 30. One group received labetalol with dose of 10 mg over 10 min from 45 min before finishing dressing and then 0.75 mg/min until 35 min later; another group received morphine in bolus dose of 0.1 mg/kg during 2–3 min. Blood pressure and pulse were measured every 10 min over 40 min. After operation, they were measured every 5 min over 15 min. Results: The morphine group had higher systolic (133.3 ± 18.8) and diastolic blood pressure (87.1 ± 13.6) (P = 0.021 and 0.028, respectively) at extubation and during 45 min before dressing, the diastolic blood pressure was significantly higher in compares with labetalol (75.3 ± 10.5) (P < 0.05). And extubation time was significantly shorter in labetalol group (7.7 ± 0.84) (P < 0.001). Pulse had no significant difference in both groups. In labetalol group, blood pressure and pulse fluctuations were more stable. Conclusion: Administration of labetalol 45 min before finishing dressing can significantly control blood pressure during emergence from anesthesia and also shorten the time of extubation during emergence in patients undergoing craniotomy.

Background: Molecular methods for the detection of drug-resistant tuberculosis (DR-TB) are potentially more rapid than conventional culture-based drug susceptibility testing, facilitating the commencement of appropriate treatment for patients with DR-TB. The aim of this study was to evaluate and develop polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assays for the detection of mutations within rpsL, and for the determination of streptomycin (STR) resistance in Mycobacterium tuberculosis. Materials and Methods: Clinical specimens were collected from individuals with suspected TB referred to the TB Center of Isfahan' from which 205 M. tuberclosis were isolated and identified by conventional phenotypic methods. The minimum inhibitory concentration of STR for all isolates was determined using the proportion method and 10 isolates were recognized as STR resistant M. tuberculosis. The effect of genetic alterations in the rpsL gene for these resistant isolates were investigated by PCR-RFLP method. Results: Three (30%) isolates showed point mutation at codon 43 by RLFP analysis. Conclusion: Our results suggest that RFLP analysis of the rpsL gene is useful for the rapid prediction of STR resistant strains of M. tuberculosis.

Background: Aim of this clinical trial is the evaluation of the effect of intravitreal injection of bevacizumab on acute central serous chorioretinopathy (CSC). Materials and Methods: In a nonrandomized clinical trial, 36 CSC eyes (with <1-month disease history) were examined. Initially, all the patients underwent posterior and anterior segment examinations as well as complete eye examination to evaluate the best spectacle-corrected visual acuity (BSCVA). Then, optical coherence tomography was performed to confirm the diagnosis. The patients were divided to the two groups each of 18 subjects, which 18 patients received intravitreal injection of bevacizumab (1.25 mg) and the rest of them did not receive any treatment (control group). The patients were health checked by the end of the 1^st and 3^rd months. Significance level was considered as P < 0.05. Results: In the BSCVA, no significant difference in visual improvement was observed in baseline vision compared to each other (P = 0.481). There was also no significant difference in the vision of intervention and control groups 1 and 3 months after injection (P = 0.379 and P = 0.557). A significant decrement existed in the intervention group compared with the control group in the maximum central macular thickness at 1 month after injection (P = 0.001); however, the difference was not significant when comparing the two groups at baseline and 3 months after injection (P = 0.925 and P = 0.338). Conclusion: In general, according to the results of this study, intravitreal injection of bevacizumab was not effective in improvement of patients with acute CSC, although it had no side effects.

Background: Ovarian cancer is the most common fatal malignancy of the gynecology tract. The purpose of this study was to compare serum levels of tumor markers cancer antigen 125 (CA125) and human epididymis protein 4 (HE4) in both healthy groups and patients with ovarian cancer. Materials and Methods: this case–control study was performed on Seyed Al-Shohada Hospital in Isfahan. Research on the treatment of 44 patients with ovarian cancer and 44 healthy controls was performed. CA125 and HE4 were measured in serum by sandwich ELISA method. Results: Average CA125 in ovarian cancer patients (83.30 ± 43.99 μ/ml) was significantly higher than in healthy controls (12.39 ± 5.50 μ/ml) (P < 0.001). Average HE4 in ovarian cancer patients (295.41 ± 133.33 PM) was significantly higher than in healthy controls (114.64 ± 17.31 PM) (P < 0.001). Conclusions: HE4 test is complementary of CA125 test in women with epithelial ovarian cancer. It is also used to study the disease process.

Background: To assess the clinical consequences of AcrySof toric intraocular lens (IOL) and Hoya toric IOL implantation to correct preexisting corneal astigmatism in patients undergoing cataract surgery. Materials and Methods: In this study, we examined 55 eyes of 45 patients with at least 1.00 D corneal astigmatism who were scheduled for cataract surgery. After phacoemulsification, toric IOL was inserted and axis was aligned. We observed the patients' uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), keratometry, manifest refraction, and IOL axis alignment 6 months after surgery. Results: After 6 months, the UDVA was 0.17 ± 0.17 logMAR in the AcrySof group and 0.17 ± 0.18 logMar in the Hoya group. More than 78% of eyes in the AcrySof group and 80% of eyes in the Hoya toric IOL achieved a UDVA of 20/40 or better. In the AcrySof group, the mean preoperative corneal astigmatism was 2.73 ± 0.92 D. The mean postoperative refractive astigmatism was 0.84 ± 0.63 D. In the Hoya group, the preoperative corneal astigmatism was 2.58 ± 0.76 D and the postoperative refractive astigmatism was 0.87 ± 0.66 D (P < 0.05). The mean AcrySof IOL axis rotation was 1.88° ± 3.05°. In the Hoya group, the mean axis rotation was 1.53° ± 3.66°. All changes in visual and refractive data before and after surgery were statistically significant (P < 0.05). There was no significant difference between the two groups regarding refractive and visual outcome after surgery (P > 0.05 for all). Conclusion: Implantation of AcrySof toric IOL and Hoya toric IOL was an effective way to correct preexisting corneal astigmatism in cataract surgery.

Background: Historically, substance misuse has been a serious problem faced by worldwide military personnel. Some research showed that military personnel have higher rates of unhealthy substance use than their age peers in the general population. These problems have serious consequences and may lead to significant military difficulties in the field of readiness, discipline, and mental or physical health. In this review, we gathered various methods for prevention, diagnosis, and treatment of substance use disorders and suggested a comprehensive plan for Iran Armed Forces to improve existing services. Materials and Methods: This article is a narrative review study, which was carried out on 2016. A careful literature review was performed between January 1970 and April 2016 on several national and international databases. Articles were screened according to the following inclusion criteria: (1) review articles about prevention and treatment protocols, (2) executive guidance, (3) cohort articles about risk factors of addiction, and (4) randomized controlled trials about prevention or treatment of substance use disorders in army service members. After screening by title and abstract, 130 articles selected of 832 founded articles, and after quality assessment, finally, 63 articles included in the review. Results: There is a necessity to manage substance use disorder through prevention, screening, and then referral to proper services for diagnosis and treatment. Urinalysis programs for screening are cost-effective and should be considered as a main method. Effective treatment includes both behavioral and pharmacological methods. Conclusions: The ideal prevention program will include multiple and mutually reinforcing evidence-based universal, selective, and indicated attempts at both the individual and environmental levels. The implementation of screening and treatment strategies needs strict rules and national guideline for the comprehensive management of substance use disorders in army.

Background: This study aims to evaluate the incidence of stroke, ischemic heart disease (IHD), and cardiovascular disease (CVD) mortality in clusters containing hypertension (HTN), clusters containing diabetes (diabetes mellitus [DM]), cluster with both HTN, DM, and cluster without HTN, DM in patients with metabolic syndrome (MetS). Materials and Methods: The association between MetS and outcomes was examined in 2257 patients with MetS that were divided into four groups includes patients with MetS with hyperglycemia (Cluster 1), patients with MetS with HTN (Cluster 2), patients with MetS with HTN and hyperglycemia (Cluster 3) and patients with MetS without HTN and hyperglycemia (Cluster 4). To assess the risk ratio and incidence of CVA, myocardial infarction, and mortality with the use multivariate Cox proportional hazards models. Results: As it shown the lowest prevalence of events was in Cluster 1 and against in Cluster 3 the prevalence of stroke with 34 (38.2%) cases and the prevalence of IHD and CVD mortality in Cluster 2 with, respectively, 168 (54.7%) and 51 patients (49%) had the most frequencies (P < 0.001), and hence that the lowest prevalence of events was seen in Cluster 1, but stroke in Cluster 3 with 34 cases (38.2%) and the prevalence of IHD and CVD mortality in Cluster 2, respectively, with 168 (54.7%) and 51 patients (49%) had the most frequencies (P < 0.001). Conclusion: More intensive changes in lifestyle and management protocols may be required in these patients for controlling the components of the syndrome, with the aim of preventing not only type II diabetes and CVD but also ischemic cerebrovascular events.

Background: Intravenous pantoprazole administration in patients with severe bleeding under urgent endoscopic therapy is effective. Furthermore, its infusion dose is useful to control bleeding; however, it is not economical. In this study, clinical outcomes and intravenous infusion of pantoprazole after endoscopic therapy plus efficacy of infusion dosage and divided doses are compared. Materials and Methods: This prospective, comparative study conducted on 18 adult (>18 years) patients referred to Al Zahra Hospital for hematemesis and melena bleeding who underwent endoscopic treatment with pantoprazole which divided into two groups of forty patients. First group received intravenous infusion for 80 mg and 8 mg/h. The second group received intravenous infusion with divided doses as 40 mg twice daily for 3 days. Clinical outcomes such as rebleeding, duration of hospitalization, amount of blood transfused, and mortality within 3 days after endoscopic treatment were collected and analyzed by SPSS software (version 20) using independent t-test, Chi-square test, and Fisher's exact test. Results: Duration of hospitalization in the pantoprazole infusion group was 5.42 ± 4.62 days, with three patients (7.5%) having rebleeding, and in the divided pantoprazole group was 5.90 ± 3.08 days, with four patients (10%) having rebleeding, and overall, only one person died in the divided pantoprazole group (2.5%) out of eighty patients. No significant difference was observed between two groups in terms of clinical outcomes (P > 0.05). Conclusion: Regarding to results, it can be stated that both methods with specified dosage had significant impact on improvement of hematemesis and melena. Furthermore, due to lower costs, low dose of pantoprazole in divided approach as 40 mg/12 h is proposed.

Background: The amount of sedation and muscle relaxation of the jaw may have an impact on complications caused by laryngeal mask airway (LMA). The aim of this study is to evaluate the effect of low-dose Atracurium on conditions of insertion, complications, and hemodynamic responses to LMA insertion following induction of anesthesia with propofol, in patients undergoing cataract surgery. Patients and Methods: In this double-blind randomized clinical trial study, 60 patients were randomly divided into two groups. Initially, the patients in the study group received 0.15 mg/kg intravenous injection of atracurium, and the patients in the control group received 2 ml of intravenous injection of normal saline, after which anesthesia in both groups were induced with midazolam, fentanyl, lidocaine, and propofol. The amount of jaw relaxation, ease of insertion, and the time needed for insertion, hemodynamic responses and complications of LMA insertion were evaluated. Results: Jaw relaxation and ease of LMA insertion in the study group was significantly better than that of the control group (P = 0.02). Average time needed for LMA placement in the study group (5/06 ± 0.52 second) was significantly lower than the control group (5/76 ± 0.67 second) (P = 0.001). Hemodynamic response to LMA insertion was similar in both groups. Sore throat at recovery and 24 h after surgery in the control group was significantly higher than that of the study group (3/30 vs. 10/30) (P = 0.01). Conclusions: Using low doses of atracurium decreases the time needed for LMA insertion and sore throat after the operation. Atracurium also increases jaw relaxation and facilitates the placement of LMA.

Background: There is an increase in inflammatory and a reduction in anti-inflammatory cytokines in multiple sclerosis (MS). Considering the role of thyroid hormones in the development and regulation of both neural and immune systems, the aim of this study was to evaluate the effects of levothyroxine on serum concentrations of interleukin-10 (IL-10) and interferon gamma (IFN-γ) in animal models of MS. Materials and Methods: To induce demyelination in male Wistar rats, lysolecithin was injected into the optic chiasm. Then levothyroxine was injected intraperitoneally (20, 50, and 100 μg/kg) for 21 days. Serum levels of cytokines were measured by enzyme-linked immunosorbent assay at 7, 14, and 21 days after that. Results: The results showed that injection of lysolecithin to the optic chiasm only increased serum concentrations of IL-10 compared to the sham group (P < 0.05) at 7^th day, but this increase was prevented by all doses of levothyroxine. IFN-γ was decreased significantly (P < 0.001) 21 days after. Comparing to the sham group at all sampling time and with respect to the MS group at the days 7 and 21, levothyroxine decreased serum concentrations of IFN-γ significantly. Conclusion: The results showed that thyroid hormones probably could produce protective effects against induced demyelination through affecting immune responses.

Background: Performing audits play an important role in quality assurance program in radiation oncology. Among different algorithms, TiGRT is one of the common application software for dose calculation. This study aimed to clinical implications of TiGRT algorithm to measure dose and compared to calculated dose delivered to the patients for a variety of cases, with and without the presence of inhomogeneities and beam modifiers. Materials and Methods: Nonhomogeneous phantom as quality dose verification phantom, Farmer ionization chambers, and PC-electrometer (Sun Nuclear, USA) as a reference class electrometer was employed throughout the audit in linear accelerators 6 and 18 MV energies (Siemens ONCOR Impression Plus, Germany). Seven test cases were performed using semi CIRS phantom. Results: In homogeneous regions and simple plans for both energies, there was a good agreement between measured and treatment planning system calculated dose. Their relative error was found to be between 0.8% and 3% which is acceptable for audit, but in nonhomogeneous organs, such as lung, a few errors were observed. In complex treatment plans, when wedge or shield in the way of energy is used, the error was in the accepted criteria. In complex beam plans, the difference between measured and calculated dose was found to be 2%–3%. All differences were obtained between 0.4% and 1%. Conclusions: A good consistency was observed for the same type of energy in the homogeneous and nonhomogeneous phantom for the three-dimensional conformal field with a wedge, shield, asymmetric using the TiGRT treatment planning software in studied center. The results revealed that the national status of TPS calculations and dose delivery for 3D conformal radiotherapy was globally within acceptable standards with no major causes for concern.

Background: Human endometrium is a dynamic tissue during the menstrual cycle can be influenced by ovarian hormones. The purpose of this study was to evaluate the endometrium angiogenesis under the influence of human menopausal gonadotropin and human chorionic gonadotropin (HMG and HCG) that stimulate ovulation and progesterone. Materials and Methods: In this study, thirty adult female mice were randomly divided into three groups as: control, gonadotropin and gonadotropin + progesterone. The mice in the other two groups except the control group received 7.5 IU HMG and later HCG. Subsequently, the mice were placed in a cage for mating. Gonadotropin + progesterone group was administered, 1 mg/mouse progesterone in 24, 48, and 72 h interval, after HMG injection. Ninety-six hours after HMG injection, animals were sacrificed, and their uterine specimens were prepared by immunohistochemistry technique for light microscopic studies, and statistical analysis was carried out. Results: Endometrium angiogenesis in control group showed that mean ± standard deviation was 24.15 ± 11.15, gonadotropin group was 62.50 ± 24.16, and gonadotropin + progesterone group was 41.85 ± 19.54. Significant difference between the control group and gonadotropin group and between the control group and gonadotropin + progesterone was observed. Statistically significant differences were observed in all groups in the endometrial angiogenesis (P < 0.05). Conclusion: Ovarian induction with gonadotropins and gonadotropins + progesterone could not change the morphometrically index of endometrial glandular epithelium in mice. Ovarian stimulation followed by progesterone injection could modify the angiogenesis of mice endometrium.

Background: Hypotension is one of the most common complications after spinal anesthesia for cesarean delivery. Normally, preloading with fluids, especially crystalloids, is used to prevention of hypotension. Methods: In the present randomized clinical trial study, 120 parturients presenting for elective cesarean section with the American Society of Anesthesiologists Class I and II received either 15 cc normal saline or 7 cc/kg hydroxyethyl starch 6% (Voluven) fluid. Information regarding to systolic, diastolic, mean arterial pressure, and heart rate, incidence of hypotension, adverse effects, the total dose of atropine, and ephedrine were recorded in before and 3, 6, 9, 15, and 20 min after spinal anesthesia. Furthermore, Apgar score of newborn at the 1^st and 5^th min after birth was recorded. Results: There was no significant difference in mean arterial pressure at different stages such as: Exactly after spinal and 3, 6, 15, and 20 min after spinal anesthesia between two groups (P > 0.05). Total dose of ephedrine and atropine were similar between groups (P > 0.05), respectively. There was no significant difference in Apgar score at the 1^st and 5^th min after birth between two groups. There were not any adverse effects of drugs in two groups. Conclusions: The results of this study show that hydroxyethyl starch 6% compared to normal saline are similar to prevent hypotension during spinal anesthesia for cesarean delivery.

Background: Intradetrusor injection of botulinum toxin A (BTX-A) might serve as a minimally invasive substitute in patients with refractory idiopathic overactive bladder (RIOAB). The aim of this study was to evaluate the clinical outcomes related to two different doses of abo-BTX-A (AboBTX-A) in patients with RIOAB. Materials and Methods: This prospective clinical trial was performed on 55 women with RIOAB. After determination of trabeculation grade, 300 (no or mild) or 500 (moderate or severe) unit of AboBTX-A (Dysport) was intravesicaly injected. Before 1, 3, and 6 months after intervention, lower urinary tract symptoms during 24 h were recorded. Results: Of the study population, 62% had severe bladder trabeculation. The mean duration of overactive bladder (OAB) was 1.76 versus 5.85 years, for no or mild versus severe trabeculation, respectively. After injections of 300- and 500-unit dosage, there were 19% and 26% early complications such as urinary retention. There was a statistically significant difference between the two groups in OAB score after 1 month (P < 0.001) and duration of OAB symptoms, over three follow-up times (P < 0.001). The mean preinjection OAB scores between patients with and without recurrence were statistically significant (29.36 vs. 25.07; P < 0.03). Urinary tract infection as a late complication was distinguished in four patients. Conclusion: In RIOAB, by adjusted dosage of AboBTX-A related to the grade of bladder trabeculation, in addition to maintain efficacy, consequent complications might not be affected by dosage and the drug dosage could be increased to nearly 60% with less concern associated to complication

Background: There is evidence regarding the relationship between dietary proteins intake and blood pressure (BP), but they had inconsistent results. Therefore, this study was designed to assess the association between different kinds of protein intake (animal and plant protein) and BP. Materials and Methods: Data were collected from Isfahan Healthy Heart Program. We performed a cross-sectional study among 9660 randomly selected Iranian adults aged ≥19-year-old that they were selected from three large Iranian regions in 2007. A simplified validated 48-item-food frequency questionnaire was used to assess dietary intake including all kinds of protein. Systolic and diastolic BPs were measured in duplicate by trained personnel using a standard protocol. Multivariable regressions were applied to assess the relationship between protein intake and BP levels and the presence of hypertension (HTN). Results: More frequent consumption of animal, plant, and total protein intake were inversely associated with BP in a crude model (P < 0.001); however, after adjustment for potential confounders this relationship remained only for plant protein (P = 0.04). The risk of HTN occurrence decreased in the highest quintile of total and plant protein consumption by 19% (odds ratio [OR] = 0.81; confidence interval [CI]: [0.65–0.96]; P for trend = 0.004) and 18% (OR = 0.82; [CI: (0.67–0.94]; P for trend = 0.03), respectively. Conclusions: More frequent protein intake, especially plant protein consumption was inversely associated with BP and risk of HTN among Iranian adults.

Background: Prevalence statistics are essential for cancer control in addition to incidence and mortality data. As we know, there is no published report regarding lung cancer (LC) prevalence in Iran. Herein, we provide model-based estimates of limited time LC prevalence in Iran, 2015. Materials and Methods: Incidence numbers of LC were extracted from Iranian National Cancer Registry reports for 2003–2009. Trends were analyzed by joinpoint regression, assuming a logarithmic poisson model. Incidence numbers were projected up to 2015, using linear regression models which were trained by corrected annual percentage changes. A Monte Carlo-based model was generated, and absolute survival rates, number of incident cases, and incompleteness of Iranian cancer registry for LC were included into it. Limited-time prevalence (within 1, 2–3, and 4–5 years from diagnosis) and its respective 95% uncertainty level (UL) were estimated by age, gender, and histopathological type. Results: Five-year prevalence was estimated to be 4.21 (95% UL: 3.37–5.38) per 100,000 adult person, with a male:female ratio of 2.01. Estimated number of patients within 1, 2–3, and 4–5 years from diagnosis were 1871 (1497–2392), 993 (770–1285), and 420 (322–550), respectively. Most prevalent form of LC were squamous cell carcinoma (802; 579–999) and adenocarcinoma (319; 230–389) in males and females, respectively. Conclusion: According to our results, the most plausible estimates of number of alive LC patients within initial treatment, clinical follow-up, and cure phases were 2392, 1285, and 550 cases in Iran in 2015.

Background: Studies have shown that pentoxifylline (PTX) in addition to protective effects on blood vessels probably has positive influence against the brain inflammation. Therefore, the aim of this study was to evaluate the effects of PTX on serum levels of interleukin 10 (IL-10) and interferon gamma (IFN-γ) and passive avoidance learning in lipopolysaccharide (LPS)-induced inflammation in rats. Materials and Methods: Inflammation was induced by intraperitoneal (i.p.) injection of LPS (0.5 and 5 mg/kg) in male Wistar rats. After a week, PTX (25 mg/kg; i.p.) was injected for 14 days. Passive avoidance learning test was used for evaluation of learning and memory. Serum levels of cytokines were measured by enzyme-linked immunosorbent assay. Results: The behavioral results did not show any significant effect of LPS and PTX on learning and memory. Both doses of LPS (0.5 and 5 mg/kg) decreased IL-10 significantly (P < 0.05). PTX prevented this reduction just in the LPS 0.5 mg/kg + PTX 25 mg/kg group. Serum level of IFN-γ was increased only in the LPS 0.5 mg/kg + PTX 25 mg/kg group comparing to the LPS 0.5 mg/kg group (P < 0.05). Conclusions: The results showed that LPS-induced inflammation decreased the serum levels of IL-10. PTX could prevent these decreases only in mild inflammation. Both PTX and LPS-induced inflammation had no significant effects on learning and memory; therefore, their effects on CNS require further study.

Background: Magnesium (Mg) is an essential mineral required to regulate body temperature, nucleic acid, and protein synthesis with an important role in maintaining nerve and muscle cell electrical potentials. It may reduce fetal growth restriction and preeclampsia as well as increase birth weight. This study aimed to assess the effects of consuming Mg supplementation during pregnancy on pregnancy outcomes. Materials and Methods: This is a randomized controlled trial with three sixty populated groups of pregnant women. Participants were randomized to treatment or control groups through random table numbers. Participants with Mg serum levels more than 1.9 mg/dl considered as control group A randomly. They just received one multimineral tablet once a day until the end of pregnancy participants with hypomagnesemia consider as Group B and C. Participants in Group B received one multimineral tablet daily until the end of pregnancy. Participants in Group C received 200 mg effervescent Mg tablet from Vitafit Company once daily for 1 month, and also they consumed one multimineral tablet from Alhavi Company, which contains 100 mg Mg, once a day until the end of pregnancy. Intrauterine growth retardation, preterm labor, maternal body mass index, neonatal weight, pregnancy-induced hypertension, preeclampsia, gestational diabetes mellitus, cramps of the leg Apgar score were compared between three groups. Results: In all pregnancy outcomes, Group C that received effervescent Mg tablet plus multimineral showed a better result than other groups, and frequency of complications of pregnancy was fewer than the other two groups and showed a significant difference. Conclusion: Mg supplement during pregnancy likely decrease probability occurrence of many complications of pregnancy.

Background: The objective of this study is to indicate the role of urokinase plasminogen activator receptor (uPAR), soluble uPAR (suPAR), and β1 integrin in tumor growth and invasion of lymph nodes from Hodgkin's lymphoma (HL) patients. Materials and Methods: In this study, 25 lymph nodes from HL patients were analyzed for the expression of β1 integrin and uPAR on mononuclear cells using two-color flow cytometry and immunohistochemical analysis. Moreover, the levels of suPAR in the serum samples of HL patients were measured and compared with 32 healthy controls. Results: Flowcytometry and immunohistochemical results indicated no significant association of uPAR expression with tumor size, different stages, or different histological subtypes of HL; however, an increased expression of β1 integrin was detected in the advanced stages of HL. Higher expression of β1 integrin was detected in nodular sclerosis compared to lymphocyte predominant. No significant difference was observed between the serum levels of suPAR in patients with different stages of HL and healthy controls. Moreover, the levels of suPAR were significantly higher in nodular sclerosis in comparison with other subtypes. Conclusions: This study showed that the levels of suPAR and β1 integrin varied between different histological subtypes of HL. Although uPAR may play only a minor role in the growth and metastasis of lymphoma, β1 integrin may be important in predicting prognosis and metastasis in HL.

Background: Nutritional intake is an important issue in adolescent athletes. Proper athletes' performance is a multifactorial outcome of good training, body composition, and nutritional status. The aim of the present study was to assess nutritional status, body composition, and cardiometabolic factors in adolescent elite athlete's province of Isfahan, Iran. Materials and Methods: In this cross-sectional study, 100 adolescent elite athletes from volleyball, basketball, and soccer teams were selected for the study. Demographic, anthropometric, and cardiometabolic parameters were assessed. Nutritional intakes of participants were recorded using three 24-h recall questioners. Results: Thirty-four female athletes and 66 male athletes participated in this study. Body mass index had not significantly different between the sexes. Energy, protein, carbohydrate, iron, and fat intakes were significantly higher in male athletes (P = 0.02), but calcium and folic acid intakes were not significantly different between the sexes, and Vitamin D intake was significantly higher in females (P = 0.01). Systolic and diastolic blood pressure was significantly higher in males (P = 0.04) and heart rate had not significantly different between the sexes (P = 0.09). Heart murmurs and heart sounds in the majority of participants were normal. Conclusion: All the evaluated anthropometric and cardiometabolic parameters were in normal range in the majority of participants. The results showed that dietary intake in these athletes is approximately normal but micronutrients intake status in these athletes needs to be investigated further and longer.

Background: Arteriovenous fistula (AVF), permanent catheter (PC), and vascular graft are three vascular access types used for hemodialysis procedure. Due to insufficient reliable information on the comparison between AVF and PC, this study was conducted to compare AVF and PC regarding dialysis adequacy. Materials and Methods: This prospective study was carried out from March, 2013 to September, 2013. In this study, 76 hemodialysis patients were enrolled and assigned to two unequal groups of AVF and PC. Before and after the dialysis session, blood samples were taken for laboratory examinations and measurement of urea reduction ratio (URR) and Kt/V. The patients were followed up for six months, and then laboratory examinations were repeated. Results: Of the 76 hemodialysis patients, 30 had AVF and others PC. During the 6-month follow-up, 24 patients in PC group but only one patient in AVF group showed infection (P = 0.006), while in each group, three cases of thrombosis were seen (P = 0.58); however, catheter dysfunction was seen in 13 patients of PC group but no patients of AVF group (P = 0.004). There was no difference between the two groups in Kt/V and URR at the beginning of the study; however, after six months, Kt/V and URR were greater in AVF group (P < 0.05). Conclusions: In addition to some advantages of AVF over PC, such as lower rate of infection and thrombosis, we also found better dialysis adequacy in AVF group. We recommend that AVF be created in all of patients with chronic kidney disease who are candidates for hemodialysis.

Background: The most important risk that threatens the skin wounds is infections. Therefore, fabrication of a membrane as a wound dressing with the ability of antibiotic delivery in a proper delivery rate is especially important. Materials and Methods: Poly(glycerol sebacate) (PGS) was prepared from sebacic acid and glycerol with 1:1 ratio; then, it was added to gelatin in the 1:3 ratio and was dissolved in 80% (v/v) acetic acid, and finally, ciprofloxacin was added in 10% (w/v) of polymer solution. The gelatin/PGS membrane was fabricated using an electrospinning method. The membrane was cross-linked using ethyl-3-(3-dimethylaminopropyl) carbodiimide ethyl-3-(3-dimethylaminopropyl)carbodiim (EDC) and N-hydroxysuccinimide (NHS) in different time periods to achieve a proper drug release rate. Fourier-transform infrared (FTIR) spectroscopy was being used to manifest the peaks of polymers and drug in the membrane. Scanning electron microscopy (SEM) was used to evaluate the morphology, fibers diameter, pore size, and porosity before and after crosslinking process. Ultraviolet (UV)-visible spectrophotometry was used to show the ciprofloxacin release from the cross-linked membrane. Results: FTIR analysis showed the characteristic peaks of gelatin, PGS, and ciprofloxacin without any added peaks after the crosslinking process. SEM images revealed that nanofibers' size increased during the crosslinking process and porosity was higher than 80% before and after crosslinking process. UV-visible spectrophotometry showed the proper rate of ciprofloxacin release occurred from cross-linked membrane that remaining in EDC/NHS ethanol solution for 120 min. Conclusion: The obtained results suggest that this recently developed gelatin/PGS membrane with controlled release of ciprofloxacin could be a promising biodegradable membrane for wound dressing.

Background: Resuscitation of children in different treatment wards is a challenge. Given that the pediatric drug dosing is based on weight and weighing is not practical in emergency situations, it is critical to employ a fast, easy, and reliable technique. Hence, this study attempted to evaluate the real weight children against Broselow estimation. Materials and Methods: This cross-sectional study involved 1500 children of 2–24 months referred to Isfahan urban and rural health centers in 2015. Children's estimated weights were measured based on the standard Broselow tape and real weights through a digital scale. The factors such as age, sex, height, arm circumference, head circumference, and living place of children were recorded. The collected data were analyzed through independent t-test, ANOVA, and linear regression using SPSS (version 20). Results: The weight difference of children through Broselow estimation was 0.019 kg, and the correlation coefficient was 0.893 (P > 0.05). The difference sorted by age ranges was significant only in >12 months (P < 0.05). It was estimated at error of 10% to be 68.9% correctly. The mean weight estimation error was significant sorted by weight, sex, habitus, and living place of children (P < 0.001). Conclusion: Although Broselow tape has been proved to be accurate it led to a significant error at different age ranges. Hence, the present study estimated the age, arm circumference, and height of Iranian children based on new formulas providing more successful tool through controlling the confounding factors in estimating the real weight.

Background: Candida species can become opportunistic pathogens causing local or systemic invasive infections. Gastroesophageal candidiasis may depend on the Candida colonization and local damage of the mucosal barrier. Risk factors are gastric acid suppression, diabetes mellitus, chronic debilitating states such as carcinomas, and the use of systemic antibiotics and corticosteroids. The aim of this study is collection and molecular identification of Candida species from gastroesophageal lesions among pediatrics in Isfahan, and determination of minimum inhibitory concentration (MIC) ranges for clinical isolates. Materials and Methods: A total of 200 patients underwent endoscopy (130 specimens from gastritis and 70 samples from esophagitis) were included in this study between April 2015 and November 2015. All specimens were subcultured on sabouraud dextrose agar, and genomic DNA of all strains was extracted using boiling method. Polymerase chain reaction and DNA sequencing of the ITS1-5.8SrDNA-ITS2 region were used for the identification of all Candida strains. MIC ranges were determined for itraconazole (ITC), amphotericin B (AmB), and fluconazole (FLU) by E-test. Results: Twenty of 200 suspected patients (10%) were positive by direct microscopy and culture. Candida albicans was the most common species (60%) followed by Candida glabrata (30%), Candida parapsilosis (5%), and Candida kefyr (5%). MIC ranges were determined for FLU (0.125–8 μg/mL), ITC (0.008–0.75 μg/mL), and AmB (0.008–0.75 μg/mL), respectively. Conclusion: Every colonization of Candida species should be considered as a potentially factor of mucocutaneous candidiasis and should be treated with antifungal drugs.

Nonneoplastic demyelinating processes of the brain with mass effect on magnetic resonance imaging can cause diagnostic difficulties. It requires differential diagnosis between the tumefactive demyelinating lesion and the coexistence of neoplasm. We document the case of 41-year-old woman with clinical and radiological findings suggestive of multiple sclerosis. Additional investigations confirmed the coexistence of astrocytoma. This report emphasizes the importance of considering brain tumors in the differential diagnosis of primary demyelinating disease presenting with a cerebral mass lesion.

Background: Cisplatin (CP) is accompanied with a nephrotoxicity. L-arginine (LA) plays an important role in the regulation of renal function. The present study was designed to investigate the protective role of LA supplementation in CP-induced nephrotoxicity in a diabetic rat's model. Materials and Methods: Sixteen adult female and male Wistar rats were used and they received a single dose of streptozotocin (STZ) (60 mg/kg i.p.). Diabetic female and male rats were arranged as groups 1–5 and groups 6–10, respectively. Groups 1 and 6 (LA groups) received LA alone. Groups 2 and 7 (CP groups) received CP alone. Groups 3 and 8 (CP + LA [PT] groups) received LA as prophylaxis and then treated with LA and CP. Groups 4 and 9 (CP + LA [T] groups) were treated with LA and CP simultaneously. Groups 5 and 10 (CP + LA [P] groups) received LA as prophylaxis and then treated with CP. Results: The serum creatinine (Cr) level of males in Groups 8 and 9 was significantly increased when compared with LA and CP (P < 0.05), whereas no differences were observed in Cr level in female groups. Blood urea nitrogen/Cr ratio and kidney weight were reduced in all CP-receiving male rats. Such observation was not seen in female rats. Different results related to weight loss were obtained between male and female animals. The kidney tissue damage score in CP + LA (PT) male group was significantly greater than CP group (P < 0.05). Conclusion: Our findings indicate that administration of LA in female and male rats has no protective effect on the severity of nephrotoxicity induced by CP in diabetic rats.

Background: Some studies have shown that a preoperative high concentration of thyroglobulin (Tg) in wash out of fine-needle aspiration cytology of cervical lymph nodes mandate therapeutic lymph node dissection. However, there is disagreement about the minimum concentration of Tg which could have diagnostic value. Hence, according to our literature review, this study is the first one which designed to do intraoperatively. Therefore, this study was conducted and aimed to determine the clinical diagnostic value of Tg lymph nodes in the diagnosis of metastatic thyroid cancer. Methods: In a cross-sectional study, 65 patients with papillary thyroid carcinoma (PTC) who were thyroidectomy candidates were chosen and during surgery, before the removal of lymph nodes in the neck, fine-needle sampling was performed and the level of Tg in the samples, nature of the sample sent for biopsy and Tg levels in affected and unaffected lymph nodes were determined. Results: The mean levels of washout Tg in malignant and nonmalignant lymph nodes were 622.1 ± 66.2 and 1.38 ± 0.43 ng/ml, respectively, and the difference between the two groups was significant (P < 0.001). The Tg cut-off point for the detection of lymph node metastases was 0.7 ng/dl, and according to it, Tg washout sensitivity was 93.8%, specificity of 92.4%, false positives 7.76%, false negatives 6.3%, positive predictive value was 92.3%, and negative predictive value was 93.8% and accuracy was 93.1%. Conclusion: Based on the results, Tg level of cervical lymph nodes in patients with PTC is a suitable criterion for the diagnosis of lymph node which can be determined through fine-needle biopsy. Therefore, it is suggested that in patients with suspicion of lymph nodes involvement during surgery, fine-needle biopsy and determination of the Tg level performed.

Background: Some studies showed a relation between chondrocalcinosis and osteoarthritis (OA). Hence, considering the importance of chondrocalcinosis diagnosis andnecessity for its integration with OA, the current study aims at investigating prevalence of chondrocalcinosis in patients above 50 years admitted to Isfahan Al-Zahra Medical Center and its relationship with OA. Materials and Methods: In a cross-sectional study, 600 patients who referred to the radiology units of Al-Zahra Hospital for radiography of different joints were studied during 2013–2014. The patients images were studied for chondrocalcinosis and OA by a radiologist and also examined clinically and results of imaging by an expert rheumatologist. The prevalence of chondrocalcinosis and it relation with OA was determined by Statistical Package for Social Sciences software and using of Chi-square and t-test. Results: 23 patients under study had chondrocalcinosis (3.83%). patients with chondrocalcinosis had higher age average, and they were in age group of 70 years and older, but no significant difference was observed regarding the prevalence of the disease in both genders. Chondrocalcinosis prevalence in terms of body mass index showed significant differences (P = 0.001). All patients with chondrocalcinosis had a history of joint disease and prevalence of chondrocalcinosis in terms of joint disease history showed a significant difference (P < 0.001). Conclusion: Prevalence of chondrocalcinosis is relatively high in the Iranian population of 70 years and older. Hence, more investigation considering to the diagnosis of chondrocalcinosis among patients with OA is very important.

Background:Staphylococcus aureus has the ability to form biofilms on any niches, a key pathogenic factor of this organism and this phenomenon is directly related to the concentration of NADPH. The formation of NADP is catalyzed by NAD kinase (NADK) and this gene of S. aureus ATCC 12600 was cloned, sequenced, expressed and characterized. Materials and Methods: The NADK gene was polymerase chain reaction amplified from the chromosomal DNA of S. aureus ATCC 12600 and cloned in pQE 30 vector, sequenced and expressed in Escherichia coli DH5α. The pure protein was obtained by passing through nickel metal chelate agarose column. The enzyme kinetics of the enzyme and biofilm assay of the S. aureus was carried out in both aerobic and anaerobic conditions. The kinetics was further confirmed by the ability of the substrates to dock to the NADK structure. Results: The recombinant NADK exhibited single band with a molecular weight of 31kDa in sodium dodecyl sulfate-polyacrylamide gel electrophoresis and the gene sequence (GenBank: JN645814) revealed presence of only one kind of NADK in all S. aureus strains. The enzyme exhibited very high affinity for NAD compared to adenosine triphosphate concurring with the docking results. A root-mean-square deviation value 14.039Š observed when NADK structure was superimposed with its human counterpart suggesting very low homology. In anaerobic conditions, higher biofilm units were found with decreased NADK activity. Conclusion: The results of this study suggest increased NADPH concentration in S. aureus plays a vital role in the biofilm formation and survival of this pathogen in any environmental conditions.

Background: Diabetes mellitus can change the risk of developing cancer. Cisplatin (CP) is a common antineoplastic drug. The major side effect of CP is nephrotoxicity. Gamma amino butyric acid (GABA) is an antioxidant agent that may have a protective role against CP-induced nephrotoxicity. The aim of the present study was to investigate the role of GABA in CP-induced nephrotoxicity in hyperglycemic male and female rats. Materials and Methods: Sixty male and female Wistar diabetic rats were used in ten experimental groups. GABA alone groups received GABA (50 μmol/kg/d i.p.) for 12 days. CP alone groups received CP (2.5 mg/kg/d i.p.) for 6 days. Other groups received GABA in the form of therapy (T) + CP, prophylaxis (P) + CP, and prophylaxis-treatment (PT) + CP. Finally, blood samples were obtained, and animals were killed for kidney tissue investigation. Results: In female rats, the serum levels of creatinine (Cr) did not change by GABA rather than CP and also there were no significant changes in blood urea nitrogen to creatinine ratio (BUN/Cr). In male rats, plasma Cr level increased by GABA (P) and (T). Body weight loss was significantly different among groups (P < 0.05). BUN/Cr ratio significantly increased in CP and GABA (PT) + CP groups. In two genders, plasma Cr level significantly decreased in CP groups (P < 0.05). The kidney levels of malondialdehyde enhanced significantly in CP groups. Conclusion: Hyperglycemia has protective effect against CP-induced nephrotoxicity. GABA did not change this effect in female, but in male in the form of PT, GABA maintained it.

Hirayama's disease is a rare clinical variant of amyotrophic lateral sclerosis where distal muscles are involved more compared to proximal muscles and vice-versa occurs only in 10% cases and so it is differentiated from O'Sullivan McLeod syndrome which involves only small muscles of single limb. Here, we present a case of Hirayama's disease where disease achieved a plateau after 3 years with no further progression. His electrophysiological studies, and clinical picture, and magnetic resonance imaging findings were consistent with a diagnosis of Hirayama's disease.

Background: This study aimed to evaluate the situation of Bone Mineral Density (BMD), Z score, T score, serum level of corrected and ionized calcium, alkaline phosphatase and 25-hydroxy vitamin D in percutaneous transhepatic cholangiography (PTC) patients and correlation of these variants with thyroid stimulating hormone (TSH) suppression level by levothyroxine. Materials and Methods: Among the patients referred to Esfahan's endocrinology research center, 34 PTC patients (aged 20– 50 years) with a history of thyroidectomy and conceived radioactive iodine and suppressive dose of levothyroxine were evaluated in this case– control study, and 38 healthy persons participated as the control group (matched by age and sex, body mass index). Bone density was evaluated with the DEXA method in four areas: Lumbar spine, femoral neck, and trochanter and distal of forearm. A reference laboratory assessed TSH, corrected and ionized calcium, Alkaline phosphatase (ALP) and 25OH vitamin D levels using fasting plasma and evaluated correlation of TSH level with variants by multivariate variance analysis. Results: There was no significant difference in bone density and laboratory data (unless TSH) between the groups. In the PTC group, there was no significant correlation between TSH and difference values of BMD, Z score or T score, corrected calcium (P value = 0.12), ionized calcium (P = 0.54), ALP (P = 0.22) and 25 OH vitamin D (P = 0.38). There was no significant correlation in the TSH subgroups with BMD. The TSH suppression level has no relation with the elevated prevalence of low BMD, hypocalcemia and vitamin D deficiency. Difference in odds ratio was not significant for osteopenia and osteoporosis between the TSH subgroups (TSH < 0.02, >0.02 and <0.1 and >0.1 mu/L). Conclusion: Suppressive therapy with levothyroxine cannot decrease BMD, Z score and T score in PTC patients.

Background: Panton-Valentine leukocidin (PVL) is a gamma-toxin produced by Staphylococcus aureus encoded by genes lukS/lukF-PV with several single-nucleotide polymorphisms. A mutation at nucleotide position 527 results in substitution of histidine (H) to arginine (R) at amino acid 176. The groups defined based on the amino acid change, the “R isoform” group and the “H isoform” group. The purpose of this study was to determine the frequency of PVL gene isoforms in S. aureus strains isolated from patients at Al-Zahra Hospital Isfahan and molecular characterization of PVL-positive methicillin-resistant S. aureus(MRSA) strains including the detection of mecA gene and staphylococcal chromosomal cassette mec (SCCmec) typing. Materials and Methods: In this study, 130 isolates of S. aureus were collected from Al-Zahra Hospital. The PVL gene identified using polymerase chain reaction (PCR); PCR products were sequenced to identify the type of isoform. The molecular characterization of isolates of PVL-positive MRSA including detection of mecA gene by PCR and also SCCmec typing was performed by multiplex PCR. Results: Out of 130 isolates, 23% were positive for the presence of PVL genes. The PVL positive isolates were comprised 37% (11/30) of methicillin-resistant isolates and 63% (19/30) of methicillin-susceptible S. aureus (MSSA) isolates. The results showed that 17 isolated carrying isoform H and 13 isolated carrying the R isoform. Conclusion: The PVL gene was predominantly found in MSSA isolates. There was no relation between PVL isoforms and the presence of mecA and SCCmec types.

Background: Diagnostic value of multi-slice computed tomography (MSCT) for detecting in-stent restenosis in comparison with conventional coronary angiography remained uncertain. The present study aimed to determine the value of MSCT for detecting in-stent restenosis.Materials and Methods: This historical cohort study was included 226 patients with the history of percutaneous coronary intervention from 2000 to 2014 that referred to MSCT Unit at Alzahra Heart Center in Isfahan. The subjects were followed-up by telephone with regard to performing coronary angiography up to 3 months after MSCT and their status about cardiac events. Results: Among all participants, 63 stents (27.9%) underwent coronary angiography up to 3 months after MSCT that 2 stents in left circumflex artery (LCX) assessment, 2 in left anterior descending (LAD) assessments and none in right coronary artery (RCA) assessment were uninterpretable. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of MSCT was 92.9%, 66.6%. 92.9%, 66.6%, and 88.2%, respectively for detection of occlusion in LCX stents, 100%, 100%, 100%, 100%, and 100%, respectively for detection of occlusion in LAD stents, and 80.0%, 0.0%, 80.0%, 0.0%, and 66.7%, respectively for detection of occlusion in RCA stents. Overall, MSCT had sensitivity of 93.8%, specificity of 70.0%, PPV of 93.8%, NPV of 70.0%, and accuracy 89.7% for detection of coronary stent restenosis. Conclusion: MSCT has high diagnostic value for detecting in-stent restenosis. Diagnostic accuracy of MSCT for detecting stent restenosis is considerably different between the coronary arteries with the highest diagnostic values for LAD and the lowest diagnostic values for RCA.

Background: According to the lack of adequate studies on comparing the analgesic effect and complications of ketorolac with morphine in long bone fractures, this study aimed to compare the efficacy of ketorolac with morphine in patients referring to the Emergency Department with long bones damage and fracture. Materials and Methods: In this clinical trial study, 88 patients with long bone fracture were selected randomly and divided into two groups. To scale the intensity of pain, visual analog scale (VAS) were used. Intravenous ketorolac and morphine with the loading dose of 10 mg and 5 mg, respectively was administered to a group, followed by 5 mg and 2.5 mg every 5–20 min, if necessary (VAS ≥4). The pain scores before injection and at 5 min, half an hour and 1-h after the injection were measured and recorded for all patients. Results: The mean age of the ketorolac and morphine groups was 29.1 ± 12.5 and 33.2 ± 11.4, respectively. In the groups, there was 63.6% and 70.5% of male patients respectively. The mean ± SD of pain score before the injection was 7.59 ± 1 and 7.93 ± 1.09 (P = 0.13). One hour after the injection, the mean ± SD of pain in the both groups was 1.41 ± 0.9 and 1.61 ± 1.17 and the mean pain score has no significant difference in the two groups before the injection. Repeated measures ANOVA test also showed that the trend of changes in pain score had no significant difference in both groups (P = 0.08). Conclusion: According to the fewer side effects of ketorolac and effective pain release versus morphine, ketorolac could be suggested to use.

The oral squamous cell carcinoma (OSCC) is one of the most common epithelial malignancies with significant morbidity and mortality. Recent observations indicate that the clinical and histological appearance of oral mucosa may not truly depict the damage occurring at the genetic level. This phenotypic and genotypic disparity may account in part for the failure to establish effective screening and surveillance protocols, based on the traditional clinical and microscopic examination. The tumor markers are playing an increasingly important role in cancer detection and management. These laboratory-based tests are potentially useful in screening for early malignancy, aiding in cancer diagnosis, determining prognosis, surveillance following curative surgery for cancer, up-front predicting drug response or resistance, and monitoring therapy in advanced disease. A systematic review of the literature was performed based on the English titles listed in the PubMed, EBSCO, Cochrane, Science Direct, ISI web Science, and SciELO databases using the keywords. Abstracts and full-text articles were assessed. This article may help to identify the potential biomarkers for screening and the molecular pathology analysis in the high-risk patients with the OSCC.

From the discovery of cell-free fetal (cff)-DNA in 1997 so far, many studies have been performed on various aspects of cff-nucleic acid. It is undoubted that currently, invasive prenatal diagnosis progresses to the noninvasive test. However, there are many problems. One of the most challenging issues in this field is differentiation and detection of the small amount of cff-nucleic acid in maternal plasma. Many markers and methods have been used for this purpose. This review makes an attempt to review and compare the studies in the field. Six identifier markers including Y-specific sequence, polymorphisms, epigenetic difference, DNA size difference, fetal mRNA, and microRNA as well as the advantages and disadvantages of each marker are discussed. This review provides a relatively perfect set on cff-nucleic acid biomarkers in various physiological and pathological status of pregnancy, helping to review and compare the prior obtained results, and improving designation in future studies.

Introduction: Hepatitis B virus (HBV) infection and its complications are major public health problems. As it is hard to treat and control the chronic state, control of disease depends on the prevention especially by vaccination. There is an impaired immune response to vaccinations including HBV in patients with some malignancies. The aim of this study is to assess the response rate of patients undergoing chemotherapy to HBV vaccination. Materials and Methods: All patients from two hematology/oncology clinics in Isfahan, Iran with the history of at least 1 month chemotherapy who had the inclusion criteria were enrolled in a case control study. Also a sex- and age-matched control group from healthy population was selected. They were vaccinated in a schedule of 0, 1, and 6 months and were examined for antibody titers 1 month after the last dose. The titers more than 10 mIU/ml were determined as positive response to vaccination. Results: In this study, 50 patients and 50 healthy subjects were enrolled. The two groups were age and sex matched (P > 0.05). Frequency of negative responses to HBV vaccination in case and control groups were 9 (18%) and 1 (2%), respectively (OR = 10.75, CI = 1.30–88.47, P = 0.027). Of 50 patients, 54%, 12%, 22%, and 12% had breast cancer, lymphoma, gastrointestinal, and genitourinary cancers, respectively, and frequency of negative responses were 3 (11%), 1 (16%), 4 (36.4%), and 1 (16%), respectively (P = 0.167). Conclusion: According to our results, malignancy and chemotherapy will have an important effect on the immune system and cause negative response to HBV vaccination. Our results revealed the importance of passive immunity and screening for HBV infection in patients undergoing chemotherapy. Also more studies for better vaccination schedules in this group of patients are recommended.

Background: Staphylococcus aureus strains that are Panton–Valentine leukocidin (PVL) positive cause severe skin and soft tissue infections as well as necrotizing pneumonia. The presence of PVL gene is a marker for methicillin-resistant S. aureus; therefore, survey on prevalence and phylogenetic distribution of PVL is of great importance for public health. The aim of this research was molecular epidemiology survey of S. aureus PVL positive, isolated from two tertiary hospitals of Sanandaj. Materials and Methods: A total of 264 staphylococci isolates were collected from clinical specimens, hospital personnel and hospital environment of two tertiary hospitals of Sanandaj, in 2012 (Toohid and Besat). Bacterial cultures and biochemical tests were performed for S. aureus detection. Then, polymerase chain reaction (PCR) and repetitive sequence-based PCR (rep-PCR) were used for the determination of prevalence and molecular epidemiology of S. aureus PVL, respectively. Data were analyzed using the Fisher's exact test (P < 0.05). Results: From 264 staphylococci isolates, 88 (33.33%) were detected as S. aureus. Furthermore, 20 out of 88 (22.72%) strains of S. aureus were PVL positive according to PCR results. Rep-PCR showed six main clusters of S. aureus samples. PVL had similar clonality between different samples. No significant relationship was observed between PVL positive S. aureus and rep-PCR patterns (P = 0.98). Conclusion: These results showed that a clone of S. aureus PVL positive has spread between the community and hospital settings. Therefore, appropriate measures are required to prevent the spread of staphylococci and other bacteria in hospitals.

Background: Although aortic dissection is a rare disease, it causes high level of mortality. If ascending aorta gets involved in this disease, it is known as type A. According to small number of studies about this disease in Iran, this study conducted to detect the factors related to acute aortic dissection type A, its surgery consequences and the factors affecting them. Materials and Methods: In this historical cohort study, all patients having acute aortic dissection type A referring to Chamran Hospital from 2006 to 2012 were studied. The impact of two surgical methods including antegrade cerebral perfusion (ACP) and retrograde cerebral one (RCP) on surgical and long-term mortality and recurrence of dissection was determined. The relation of mortality rate and hemodynamic instability before surgery, age more than 70 years old, ejection fraction lower than 50%, prolonged cardiopulmonary bypass pump (CPBP) time and excessive blood transfusion, was assessed. Results: Surgery and long-term mortality and recurrence of dissection were 35.3%, 30.8% and 30.4%. Surgical and long-term death in the patients being operated by ACP method was lower than those one being operated by RCP (P < 0.001). Excessive blood transfusion and unstable hemodynamic condition had significant effect on surgical mortality (P = 0.014, 0.030, respectively). CPBP time and unstable hemodynamic condition affected long-term mortality significantly (P = 0.002). Conclusion: The result found that ACP is the preferable kind of surgery in comparison with RCP according to the surgical and long-term mortality.

Background: Access dilation is the most important part of percutaneous nephrolithotripsy (PCNL) that is done by different methods, especially metal telescoping and one shot. In this study, two different methods of access dilation one shot and telescoping were compared. Materials and Methods: In observational cross-sectional study, 240 patients who were a candidate for PCNL were selected and randomly divided into two groups. The first group was undergone one-shot method and the second group was undergone telescoping method. The decrease in hemoglobin (Hb), duration of hospitalization and the time of radiation exposure during access dilation was compared in two groups by SPSS software version 21, (SPSS Inc., Chicago, IL, USA). Results: The decrease of Hb level after intervention in one-shot group was 1.08 ± 1.23 g/dl and in telescoping, group was 1.51 ± 1.08 g/dl with no difference statistically (P = 0.37). The mean duration of hospitalization in one shot and telescoping group were 2.36 ± 0.67 and 2.28 ± 0.61 days, respectively. According to t-test, there was no significant difference between the two groups (P = 0.37). Average radiation exposure in one shot group was 7.13 s and in telescoping, group was 35.75 s, and there was a significant difference between the two groups (P < 0.001). Conclusion: One-shot method is superior to telescoping method due to less time for radiation exposure and no more blood loss and other complications during PCNL.

Background: Cerebral vasospasm is a prolonged, occasionally severe, but reversible narrowing of the cerebral arteries that begins 3 to 5 days after the hemorrhage becomes maximal at 14 days. This study is designed to evaluate the effect of dantrolene on the reduction of vasospasm following aneurysmal subarachnoid hemorrhage (SAH). Materials and Methods: This randomized controlled clinical trial was conducted on 32 patients with proven aneurysms in AL-Zahra hospital during 2011-2013. They were randomly divided into two groups. In all patients, daily transcranial Doppler sonography was performed and as soon as the diagnosis of vasospasm onset in the first group, in addition to conventional treatment of vasospasm 2.5 mg/kg Dantrolene infusion within 60 minutes and while the blood pressure and heart rate of patient monitored, and arterial flow velocity changes such as PSV and MFV were measured by transcranial Doppler sonography in 45, 90 and 135 minutes. Data was analyzed by SPSS 22 and Chi-square, Student t, Mann-Whitney and ANOVA tests with repeated observations. Results: There was no significant difference in the site of the aneurysm in the two groups. The mean of PSV index prior to treatment and the 45^th minute was not different but at 90^th and 135^th minutes it was significantly lower in the Dantrolene receiving group (P < 0.05). The mean of MFV index prior to intervention and in the 45^th minute was not different between two groups, but at 90^th and 135^th minutes was significantly lower in the target group Conclusion: Using dantrolene in patients with artery vasospasm significantly reduced artery spasm and increased the patient recovery.

Most of the vascular lesions on head and neck soft tissue are congenital, but a rare cause can be trauma. A 23-year-old man came to our clinic with a wide pulsatile tortuous mass in the left temporofrontal area. That mass was appeared since 10 years ago. Ten years before his coming to our clinic, he had a blunt trauma in that area. After that, a small wound appeared there and healed gradually. In clinical examination, mass was large and pulsatile, and a fine murmur was detected from it. In paraclinical examination, computed tomography scan with intravenous contrast and sonography revealed a vascular mass with arteriovenous (AV) fistula in soft tissue only in that area. We operated him and vascular mass completely excised without recurrency. Pathologic report was AV malformation (AVM). According to our study, also rare trauma is one of the causes of AVMs, and we able to resection it completely without recurrency.

Background: This study was done to evaluate the relationship between the time of endoscopy in patients with upper gastrointestinal bleeding with morbidity and mortality rates of patients at the Al Zahra Hospital emergency room. Materials and Methods: In a cohort study, 1152 patients at 2014 and 2015 have been hospitalized due to gastrointestinal bleeding in Al Zahra Hospital, were selected and demographic and clinical information and day and time of endoscopy and hospital mortality and fewer deaths than a month after discharge were studied, and prognosis was analyzed in terms of day and time of endoscopy. Results: Nine hundred and seventy-three cases (84.5%) of endoscopy were performed during the working days and 179 (15.5%) were performed on holidays. Moreover, 801 cases (69.5%) of endoscopy were done in the morning and 351 cases (30.5%) were performed in the evening and night shifts. The day and time of endoscopy had no significant effect on mortality in hospital and less than a month after but hospital death in whom underwent endoscopy by fellowship was significantly higher (P = 0.004). Conclusion: Endoscopy in nonholiday and holiday days and the time of endoscopy has no significant effect on hospital mortality 1 month after discharge. However, other factors such as endoscopy by attendant or fellowship, time between admission to endoscopy, age and sex of the patients, etc., were significantly effective on in-hospital mortality and death 1 months after discharge. Also faster and sooner endoscopy cannot reduce rate of blood transfusions or reduce the length of hospital stay but faster endoscopy of patients can reduce the risk of in-hospital death.

Background: Infection of B-cells with Epstein–Barr virus (EBV) leads to more and subsequent immortalization. This is considered as the method of choice for generating lymphoblastoid cell lines (LCLs). Producing LCLs, although very useful but is very time consuming and troublesome, drives the requirement for quicker and more reliable methods for EBV-driven B-cell transformation.Materials and Methods: After successfully production of LCLs, different parameters including temperature, serum concentration, type of culture medium, and CO₂concentration were evaluated on EBV-transformed B-cells. In this study, we were able to produce LCLs and optimize condition. Results: The best condition for generating LCLs was 37°C, 5% CO₂, 20% fasting blood sugar, and RPMI 1640. The study results were to establish a reliable method for producing LCLs that can be used to produce immortalized B-cells from almost any sources. Conclusion: This can help with tumorgenecity studies, as well as producing control material for rare genetic disorders and so on. The aim of this study was to determine optimized condition for reliable and reproducible LCLs from different sources.

Background: The aim of this study was survey of the effect of Vitamin D supplementation on the incidence of gestational diabetes (GDM) in pregnant women. Materials and Methods: This randomized clinical trial was conducted at Alzahra and Shahid Beheshti Hospital in Isfahan, Iran, from January, 2013 to January, 2014 on 210 pregnant women referred to gynecology clinics. Serum levels of Vitamin D were measured, and those with lower serum levels of 10 nmol/L randomly divided into two groups of A and B. Pregnant women with normal Vitamin D level assigned as Group C. Group A was given 50,000 IU Vitamin D supplement every 2 weeks for 10 weeks, and Group B were given the omega-3 pearl as placebo. Then, the incidence of GDM was measured in 24–26 weeks of pregnancy with glucose tolerance test and compared in three groups. Data were analyzed using SPSS version 20 by descriptive statistics, Chi-square and Logistic regression. Results: The mean age of participants was 24.76 years (8.02 standard deviation, range 16–36 years). The incidence of GDM at 24–26 weeks gestational age were 8.57% in normal Vitamin D group, 10.00% in Vitamin D deficiency with treatment group, and 11.43% in Vitamin D deficiency without treatment group. The difference between groups in terms of incidence of GDM was not statistically significant (P = 0.112). Conclusion: Vitamin D supplementation had not effect on incidence of GDM during pregnancy.

Background: To compare refractive index variation between Hoffer-Q, Haigis and SRK/T formulas used for preoperative biometry calculation in patients with axial length >25 mm, undergoing cataract surgery. Materials and Methods: This is a randomized clinical trial study was performed on 54 eyes of 54 patients with ages of 40–70 years old and axial length >25 mm classified into three groups that their IOL POWER were calculated by Haigis, SRK/T and Hoffer-Q formulas before undergoing cataract surgery. Their refractive index variations were calculated from the difference between predicted refractive error formula and actual post-operative refractive error formula. The collected data was entered in SPSS software and was analyzed by ANOVA and Chi-square statistical test. Results: With comparison sphere, astigmatism and spherical equivalent indexes before and after of cataract surgery between Haigis, SRK/T, and Hoffer-Q formulas, statistically significant differences were found between the mean of sphere and SE indexes in patients with use of Haigis and SRK/T formulas that have been more favorable post-operative refraction. Conclusions: Haigis formula and then, with slight difference, SRK/T formula have better and more acceptable post-operative refraction results than Hoffer-Q formula in patients with high axial myopia. Therefore, it is recommended using Haigis and SRK/T formulas for IOL power calculation in patients with high axial myopia undergoing cataract surgery.

Background: One of the gene expression regulatory mechanisms is mediated by small noncoding RNAs called microRNA (miRNA). They interact with a recognition sequence located mostly in 3'-untranslated regions (3'-UTRs) of mRNAs. Polymorphisms in miRNAs recognition sequences could affect gene expression which in turn may alter disease susceptibility. SET8, a member of the SET domain-containing methyltransferase, acts in a variety of biological processes such as genomic stability. Here, we report correlation of rs16917496 polymorphism, located in the recognition sequence of miR-502 within 3'-UTR of SET8, with colorectal cancer (CRC) in Iranians. Materials and Methods: One hundred and seventy CRC patients and 170 noncancer counterparts were recruited in this case–control study. Genotyping of rs16917496 was performed using polymerase chain reaction-restriction fragment length polymorphism method. Results: There was no significant association of rs16917496 with CRC in population under study (P value for genotype and allele distribution were >0.05). However, stratification analysis based on smoking status revealed that TT+TC genotypes of SET8 rs16917496 are strongly associated with increased risk of CRC (odds ratio: 5.8, 95% confidence interval: 1.37–24.34, P - 0.005) in smoker subgroup. Conclusion: Correlation of rs16917496 T allele with CRC in smokers is emphasizing the importance of individuals' genotype in the recruitment of adverse health hazards of smoking more profoundly for certain people compared to others.

Background: Quinazolinon as an important class of heterocycles is attractive in medicinal research areas due to their wide range of biological effects. Cytotoxic activities of the quinazolinone derivatives in various cell lines including: HeLa, L1210 (mouse lymphocytic leukemia) and HT29 (human colon adenocarcinoma) were reported. Materials and Methods: In this study, a number of newly made tricycles quinazolinone derivatives such as fused pyridazino-quinazolinones and fused pyrrolo-quinazolinones were evaluated on two cancerous cell lines, melanoma (B16F10) and prostate (PC3) using the 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide colorimetric assay. Results: The results of cytotoxicity evaluations indicated that almost all of the compounds at the concentrations of 10 and 100 μM showed significant differences in viability in comparison with negative control at 48 h exposure (P < 0.05). However, during 24 h exposure some of the compounds showed cytotoxicity activity. Conclusion: Results showed that both cell lines were sensitive to synthesized compounds and longer duration of exposure (48 h) had better results compared to that of 24 h screening.

Background: A large number of stroke patients are not the perfect candidate for craniotomy and invasive procedures, so providing an alternative and noninvasive method, which is applicable in terms of costs and facilities, is necessary. Thus, the present study aimed to determine the effects of mannitol 20% on outcome of the patients with nontraumatic intracerebral hemorrhage (ICH) in patients admitted to Isfahan's Al-Zahra Hospital during 2012 and 2013. Materials and Methods: This is a clinical trial study which is conducted during 2012–2013 in Isfahan's Al-Zahra Hospital. In this study, 41 patients suffering from ICH received mannitol 20% for 3 days, and volume of hemorrhage and Glasgow Coma Scale (GCS) of patients were controlled every 12 h. The collected data were analyzed via SPSS software. Results: The mean ICH volume was 22.1 ± 6.3 ml in pre intervention and 38.4 ± 19.3 ml in post intervention, and according to the t-paired test, before and after treatment the difference was significant (P < 0.001). Hemorrhage volume was stable in nine patients (22%), it increased in 25 patients (61%), and decreased in seven patients (17.1%). The mean index of GCS before and after treatment was 11.85 ± 1.6 and 9.37 ± 2.65, respectively. Moreover according to t-paired test, the difference was significant before and after treatment (P < 0.001). During using mannitol, the GCS index was stable in eight patients (19.5%), it increased in eight patients (19.5%) and decreased in 25 patients (61%). Conclusions: Mannitol injection was not effective in reducing hemorrhage size, and its use is not recommended, also, further studies in this field have been proposed.

Background: Pseudomonas aeruginosa is an opportunistic and Gram-negative pathogen that is used as the most important factor in burn wound infections, and due to the rapid acquisition of multidrug resistance (MDR), it causes high mortality rates in these sectors. Thus, diagnosis and assessment of antibiotic resistance patterns are very important in these patients. The aim of this study was to evaluate antibiotic resistance pattern and determining P. aeruginosa MDR. Materials and Methods: In this study, phenotypic, biochemical, and polymerase chain reaction tests were used to identify P. aeruginosa from 120 wound burn samples that 96 samples were detected to P. aeruginosa species. In the next step, according to the Clinical and Laboratory Standard Institute standard guidelines, antibiogram test was performed by disk diffusion method for amikacin, ciprofloxacin, norfloxacin, gentamicin, cefepime, aztreonam, meropenem, colistin, ceftazidime, and piperacillin-tazobactam antibiotics. Antibiotic data were analyzed by WHONET software; finally, the rate of antibiotic resistance and MDR strains was determined. Results: The highest antibiotic resistance belonged to amikacin (94.8%) and norfloxacin (90.6%); in contrast, colistin (8.3%) had the lowest and the MDR strains were MDR (95.8%) and extensively drug resistance (XDR) (87.5%). Conclusion: In this study, there was MDR with an alarming rate including MDR (95.8%), XDR (87.5%), and pan-drug resistance (0%). As a result, given antibiotics to patients should be controlled by the antibiogram results to avoid increasing MDR strains.

Background: Glioblastoma (GBM) is the most common and aggressive brain tumor, which has a poor prognosis despite the advent of different therapeutic strategies. There are numerous molecular biomarkers to contribute diagnosis, prognosis, and prediction of response to the current therapy in GBM. One of the most important markers that are potentially valuable is immortalization-specific or immortalization-associated marker named “hTERT messenger ribonucleic acid (mRNA)” the key subunit of telomerase enzyme, which is expressed in more than 85% of cancer cells, in spite of the majority of normal somatic cells. In this study, we investigated the effects of resveratrol (RSV) on this mRNA marker level, leading to cancer progression. Materials and Methods: U-87MG cell line was obtained from Pasteur Institute of Iran and treated with various concentrations of 0–160 μg/mL of RSV and at different time points (24, 48, and 72 h). To evaluate viability of U-87MG cells, standard 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was performed. Real-time polymerase chain reaction (RT-PCR) was used for comparative and quantitative assessment of human telomerase reverse transcriptase (hTERT) mRNA copy number versus control–untreated group. Results: The results of our investigation suggested that RSV effectively inhibited cell growth and caused cell death in dose-dependent (P < 0.05) and not in time-dependent manner (P > 0.05), in vitro. Interestingly, quantitative RT-PCR analysis demonstrated that at half inhibition concentration, RSV dramatically decreased mRNA expression of hTERT, the catalytic subunit of telomerase enzyme, which leads to prevention of cell division and tumor progression. Conclusion: With regard to downregulation of this immortalization-associated marker, RSV may potentially be used as a therapeutic agent against GBM.

An orbital defect causes severe facial asymmetry and disfigurement that result in an immense emotional trauma to the patient and is also associated with economic, esthetic, and psychological problems. A prosthetic replacement is the treatment of choice in helping individual to return to his normal life by producing an acceptable and lifelike appearance. This case report describes the critical areas of fabrication of ocular prosthesis for a patient with missing right eye due to trauma to eye ball in an accident. Patient had given a history of surgical enucleation of the eye 15 days after ocular trauma. A polymethyl methacrylate ocular prosthesis was planned. The technique described in this case report presents the use of both custom-made and stock eye shell in an attempt to include the benefits of both. A novel attempt was made to simulate eye movements and exact color matching to that of contralateral eye to provide a better and functional ocular prosthesis to the patient.

Background: Diabetic patients are more susceptible to cutaneous fungal infections. The higher blood sugar levels cause increasing the cutaneous fungal infections in these patients. The main objective of this study was to find the frequency of fungal infections among cutaneous lesions of diabetic patients and to investigate azole antifungal agent susceptibility of the isolates. Materials and Methods: In this study, type 1diabetes (n = 78) and type 2 diabetes (n = 44) comprised 47 cases (38.5%) with diabetic foot ulcers and 75 cases (61.5%) with skin and nail lesions were studied. Fungal infection was confirmed by direct examination and culture methods. Antifungal susceptibility testing by broth microdilution method was performed according to the CLSI M27-A and M38-A references. Results: Out of 122 diabetic patients, thirty (24.5%) were affected with fungal infections. Frequency of fungal infection was 19.1% in patients with diabetic foot ulcer and 28% of patients with skin and nail lesions. Candida albicans and Aspergillus flavus were the most common species isolated from thirty patients with fungal infection, respectively. Susceptibility testing carried out on 18 representative isolates (13 C. albicans, five C. glabrata) revealed that 12 isolates (10 C. albicans and two C. glabrata isolates) (66.6%) were resistant (minimum inhibitory concentration [MIC] ≥64 mg/ml) to fluconazole (FCZ). Likewise, eight isolates (80%) of Aspergillus spp. were resistant (MIC ≥4 mg/ml), to itraconazole. Conclusion: Our finding expands current knowledge about the frequency of fungal infections in diabetic patients. We noted the high prevalence of FCZ-resistant Candida spp., particularly in diabetic foot ulcers. More attention is important in diabetic centers about this neglected issue.

Background: Knee pain, is one of the most common causes of patients' referring to physiatric clinics, and several factors, are involved in its creation. One of these factors is pes anserine bursitis (PAB) for which various treatment methods are used. This study aims to investigate the effect of this method on reducing chronic pain in these patients. Materials and Methods: This clinical trial was conducted in 2013- 2014 on patients with PAB referring to academic, physical medicine clinics. The patients with chronic PAB (pain duration more than 3 months), who were refractory to conservative treatments, were randomly divided into two 20-member experimental groups (extracorporeal shock wave therapy [ESWT] and sham ESWT). Pain scores of all patients were measured using the Visual Analog Scale (VAS) and McGill Pain Questionnaire (MPQ) (total and present pain indexes [TPIs and PPIs]) before intervention, immediately after intervention (3^rd week), and after 8 weeks. The pain scores were then compared and statistically analyzed. Results: In the ESWT group, the mean patient pain score of the VAS and TPI in MPQ were significantly lower than in the sham ESWT group immediately after intervention (3^rd week): P=0.02, P= 0.04 respectively; and 8 weeks after the end of treatment: P=0.01, P= 0.000. Moreover, the PPI in both groups had significantly decreased over time, although in ESWT group this decrement was significantly more than sham ESWT group (P < 0.001). Conclusion: The results showed that ESWT could be effective in reducing the pain and treating PAB.

Background: Trimetazidine is a fatty oxidation inhibitor, leading to shifting of energy substrate from fatty acid oxidation toward glucose oxidation that leads to the reduction of oxygen requirement. The aims of the present study were to elucidate the effects of trimetazidine on psychomotor performance and vigilance on normal healthy volunteers. Materials and Methods: A total of 234 subjects (age 22–25 years) were recruited in this study. The volunteers were randomizing into two groups with 117 volunteers in each group. Group I received an inert starch capsule served as a control, and Group II received trimetazidine tablet 15 mg/day. The duration of therapy was 5 days. Test procedure was done at 9.00 a.m. on the psychomotor tester. Before the drug administration, prescore values were recorded and then after 5 days of therapy, the postscore values were recorded. Results: The placebo did not demonstrate a significant effect on all psychomotor performances and flicker-fusion elements (P > 0.05). Trimetazidine therapy produced a highly significant effect on all components of psychomotor performances and flicker-fusion parameters (P < 0.001) compared with pretreatment era. Conclusion: We conclude that trimetazidine improves psychomotor performance and vigilance in normal healthy volunteers through advancing total reaction time and critical flicker-fusion frequency.

Background: Cancer is a term for a large group of different diseases, all involving uncontrolled cell growth. Many of Euphorbiaceae plants have been traditionally used for the treatment of ulcers, tumors, warts, and other diseases. In addition, in the last decade, there are studies showing cytotoxic effects of different species of Euphorbia on tumor cell lines. In this study, we attempted to determine if Euphorbia turcomanica possess any cytotoxic activity. Materials and Methods: Solvents extracted the plant powder with various polarities by a maceration method, and qualitative phytochemical analyzes were carried out on them to identify the constituents. On the other hand, the possible cytotoxicity of different extracts on Hela and HT-29 tumor cells was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and 50% reduction in cell survival was considered as a cytotoxic effect. Analyze of variance followed by Student-Newman-Keuls test was used to see the differences among the groups. Results: Phytochemical analysis of E. turcomanica showed the presence of flavonoid, alkaloid, anthraquinone and tannin in plant aerial parts. Methanol-water, acetone, dichloromethane, methanol, and heptane extracts of E. turcomanica significantly reduced viability of Hela cells (P < 0.05) with inhibitory concentration 50% (IC₅₀) of 50, 90, 230, 420, and 450 μg/ml, respectively. While methanol-water, dichloromethane, methanol, ethyl acetate, and heptane extracts were cytotoxic with IC₅₀of 43, 115, 125, 250, and 390 μg/ml, respectively (P < 0.05), on HT-29 cells. Conclusion: It can be concluded that E. turcomanica is a good candidate for further study toward cytotoxic agents.

Background: Inflammatory bowel diseases (IBDs), including ulcerative colitis (UC) and Crohn's disease (CD), are chronic inflammatory disorders of the gastrointestinal tract. A combination of environmental factors and interactions with a genetic predisposition are suggested to play an important role in the etiology and pathogenesis of the IBD. Glutathione S-transferases (GSTs) are multifunctional enzymes involved in the cellular oxidative stress handling. Possible associations between GSTs gene polymorphisms and susceptibility to UC and CD have been reported in different population. The relationship between GSTM1 and GSTT1 deletion polymorphisms and susceptibility to UC and CD were investigated in the Iranian population. Materials and Methods: The study was performed in 106 IBD patients and 243 age- and sex-matched healthy Iranian controls consulting the IBD registry center of the Motahari Clinic, Shiraz University of Medical Sciences, Shiraz, Iran, between 2011 and 2013. GSTM1 and GSTT1 genotyping were performed using multiplex polymerase chain reaction and differences in the distribution of gene polymorphisms were analyzed statistically between the studied groups. Results: Statistically significant higher frequency of GSTM1 null genotype was observed in IBD patients (P = 0.01) and in the subgroup of patients with UC (P = 0.04) compared to healthy controls, whereas this was not true for CD patients. No significant association was found between GSTT1 gene polymorphism and UC or CD. Conclusions: Absence of GSTT1 functional gene does not play an important role in the pathophysiology and development of IBD, UC, and CD in Iranian population whereas GSTM1 null genotype could be considered as a possible genetic predisposing factor for more susceptibility to IBD and UC.

Background: Little information is available about chemical components of the Cousinia genus. A primary cytotoxicity screening on Cousinia verbascifolia showed moderate cytotoxic activity against OVCAR-3 ovarian and HT-29 colon cancer cells. Therefore, the aim of this study is a phytochemical investigation to identify the compounds responsible for this bioactivity. Materials and Methods: Extraction was done through percolation and fractionations by reverse phase column chromatography and normal column chromatography. Using standard 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay Fr.b8 with moderate cytotoxicity was selected for identification of major components. Fr.b8 was subjected to polyamide column chromatography. More purification was done using a new modified recycle high-performance liquid chromatography (HPLC) with flow splitter. Results: Two known compounds: Apigenin (flavone) and caffeic acid (phenolic acid) were obtained from phenolic bioactive fraction for the first time from this plant. Conclusions: Apigenin and caffeic acid with known antitumor and matrix metalloproteinase inhibitory effects seem to be the bioactive components responsible for moderate cytotoxicity of phenolic fraction. Recycle HPLC following with flow splitting is a new method useful for isolation of closely eluted compounds in HPLC chromatogram.

Background: Synthetic biocompatible bone substitutions have been used widely for bone tissue regeneration as they are safe and effective. The aim of this animal study is to compare the effectiveness of three different biocompatible bone substitutes, including nano-hydroxyapatite (nano-HA) nano-bioglass (nano-BG) and forstrite scaffolds. Materials and Methods: In this interventional and experimental study, four healthy dogs were anesthetized, and the first to fourth premolars were extracted in each quadrant. After healing, the linear incision on the crestal ridge from molar to anterior segment prepared in each quadrant and 16 defects in each dog were prepared. Nano-HA, nano-BG, and forstrite scaffold was prepared according to the size of defects and placed in the 12 defects randomly, four defects remained as a control group. The dogs were sacrificed in four time intervals (15, 30, 45, and 60 days after) and the percentage of different types of regenerated bones (lamellar and woven) and connective tissue were recorded in histological process. The data were analyzed using Mann–Whitney test (α = 0.05). Results: The difference in nano-HA and nano-BG with the control group was significant in three-time intervals regarding the amount of bone formation (P < 0.01). After 15 days, the nano-HA showed the highest amount of woven and lamellar bone regeneration (18.37 ± 1.06 and 30.44 ± 0.54). Conclusion: Nano-HA and nano-BG groups showed a significant amount of bone regeneration, especially after 30 days, but paying more surveys and observation to these materials as bone substitutes seem to be needed.

Background: The global epidemic of unhealthy lifestyle causes to increase chronic disease. It has been proven that psychological factors such as self-efficacy are responsible to success in the process of lifestyle change. Low self-efficacy is usually related to low level of physical activity and medication adherence. Objective of the study was to investigate the effects of self-efficacy, other physical symptoms on physical activity and medication adherence in patients with chronic illness in public health centers. Materials and Methods: A cross-sectional study was conducted on 483 patients with chronic diseases attended to governmental health care centers in Isfahan. Participants were chosen by systematic random sampling. Inclusion criteria were having a chronic illness at least 6-month ago while prescription of medication and willing to take part in the survey. The parts of Stanford Self-management Questionnaire were used. Data were analyzed by SPSS 18 software using the descriptive and analytic statistics. P <0.05 was considered significant. Results: Mean age of participants was 54.8 (7.22) years. The half of participants had low self-efficacy and 87.2% had low physical activity. Nearly 80% of patients had a good medication adherence. There was a significant relationship between self-efficacy and physical activity (P = 0.336, β = 1.01, P< 0.001). Conclusion: Although chronic disease patients had a good medication adherence, other self-care behaviors such as physical activity has been neglected. It is seemed that concentration on psychological factors such as self-efficacy should be considered as a proximal factor to improve self-care.

Background: Due to the recent emerging information on the antioxidant properties of soy products, substitution of soy milk for milk in the diet has been proposed by some nutritionists. We aimed to compare four distinct antioxidant measuring methods in the evaluation of antioxidant properties of industrial ultra-high temperature (UHT) milk, UHT soy milk, and their fermented products by Lactobacillus plantarum A7. Materials and Methods: Ascorbate auto-oxidation inhibition assay, 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) free radical scavenging method, hydrogen peroxide neutralization assay and reducing activity test were compared for the homogeneity and accuracy of the results. Results: The results obtained by the four tested methods did not completely match with each other. The results of the DPPH assay and the reducing activity were more coordinated than the other methods. By the use of these methods, the antioxidant capability of UHT soy milk was measured more than UHT milk (33.51 ± 6.00% and 945 ± 56 μM cysteine compared to 8.70 ± 3.20% and 795 ± 82 μM cysteine). The negative effect of fermentation on the antioxidant potential of UHT soy milk was revealed as ascorbate auto-oxidation inhibition assay, DPPH method and reducing activity tests ended to approximately 52%, 58%, and 80% reduction in antioxidant potential of UHT soy milk, respectively. Conclusions: The antioxidative properties of UHT soy milk could not be solely due to its phenolic components. Peptides and amino acids derived from thermal processing in soy milk probably have a main role in its antioxidant activity, which should be studied in the future.

Background: One of the most common reasons of elbow and forearm pain is lateral epicondylitis diagnosed based on clinical examination. The extracorporeal shock wave therapy is applied for less invasive treatments with different dosages. This study aimed to investigate the effects of high- and low-dose ESW in treating the lateral epicondylitis. Materials and Methods: This clinical trial was done in Al Zahra medical center on 40 patients who were selected randomly and divided into two groups. After VAS, the first group was treated by Duolith SD1 shock wave, energy of 0.25 mj/mm², 1000 shocks; the second was treated by focus with the energy of 0.10 mj/mm², 1000 shocks per session for 15 minutes with weekly intervals in three sessions. The patients were also treated with drugs (NSAIDs) and the visual analog scale (VAS) was reassessed 1 week after the last session and 12 weeks after finishing the treatment. Results: The mean of pain intensity during study was decreased in the two groups but reduction of pain intensity in the low-dose groups was higher than the high-dose groups (P = 0.001). Changes in other parameters including wrist extension test, middle finger extension test and PG was also similar. Conclusion: Extra corporeal shockwave therapy can be effective in treating lateral epicondylitis, but its effects usually appear in after 2 or 3 months and using the low dose of this treating method has more desirable therapeutic effects.

Background: In this randomized, double-blinded case–control study, we investigated the intravenous effects of ephedrine or phenylephrine on prevention of post–spinal hypotension in elective lower abdominal surgery under spinal anesthesia. Materials and Methods: One hundred and thirty-five patients, American Society of Anesthesiologists physical status I or II candidate for elective lower abdominal surgery under spinal anesthesia were randomized to three groups (45 each). According to their allocated group, patients received either ephedrine 2.5 mg (E group), phenylephrine (P group) 25 mic as vasopressor or the same volume of saline normal as placebo (S group) immediately after the spinal anesthesia. hemodynamic parameters, and complications were recorded. Results: Patients' demographics were similar in all the groups. The mean systolic blood pressure (SBP), diastolic blood pressure (DBP), and MAP and also heart rate were similar over time for groups E and P (P > 0.05). The incidence of reactive hypertension was more in group E than group P and placebo (P < 0.05). The incidence of nausea and vomiting were significantly lower in groups E and P in comparison with placebo (P < 0.05). Conclusion: Although the mean fall of SBP and DBP were significantly less in groups E and P compared with placebo but we did not find significant differences in prophylactic use of ephedrine or phenylephrine for prevention of post–spinal hypotension in elective lower abdominal surgery. Vasopressors infusion have added benefit of lower incidence of nausea and vomiting.

The brain is a critical target organ for thyroid hormones, and modifications in memory and cognition happen with thyroid dysfunction. The exact mechanisms underlying learning and memory impairments due to hypothyroidism have not been understood yet. Therefore, this review was aimed to compress the results of previous studies which have examined the contribution of brain tissues oxidative damage in hypothyroidism-associated learning and memory impairments.

To report a case of upper eyelid swelling and ptosis caused by silicone oil migration in a patient after sutureless 23-gauge pars plana vitrectomy and silicone oil injection. A 36-year-old female was referred to eye clinic with total retinal detachment (RD) and superotemporal giant dialysis secondary to trauma in the left eye. Transconjunctival sutureless 23-gauge pars plana vitrectomy and intraocular silicone oil (1300 centistokes) injection were performed. After about 5 months, she came back with the left upper eyelid and periorbital swelling. Palpation of the eyelid revealed soft and mobile subcutaneous small lumps that were not attached to the skin. Computed tomography scan of the orbit showed an 11 mm × 8 mm soft tissue density mass in lateral aspect of the left orbit. Transcutaneously surgical exploration was performed. The patient was seen after 1 week postoperatively and there was a significant improvement of the ptosis. Eyelid swelling and ptosis caused by silicone oil migration after RD surgery are very rare and this is one of the few reports in literature.

Background: Since epithelial cell adhesion molecule glycoprotein (EPCAM) is associated with the development and metastasis of colon adenocarcinoma, it can be helpful in predicting the tumor stage before surgery. In this study, we investigated EPCAM glycoprotein expression in colon adenocarcinoma and its relationship with tumor staging. Materials and Methods: This study was done on formalin-fixed and paraffin-embedded tissues of 71 patients diagnosed with colon adenocarcinoma, together with normal tissues around them, which were available at the archive of pathology lab of Al-Zahra hospital, Isfahan. Hematoxylin and eosin (HandE) and immunohistochemistry (IHC) staining methods for EPCAM marker were performed on paraffin-embedded blocks. Results: The percentage of staining of EPCAM glycoprotein in the tumoral and normal tissues of 71 patients with colon adenocarcinoma was studied and compared. In normal tissue, 84.5% showed strong staining, 15.5% showed moderate to strong, and none of the patients showed moderate, weak, or no staining at all. In the tumoral tissue, 25.4% had strong, 25.4% had moderate to strong, 26.8% showed moderate, 16.9% showed weak and 5.6% had no staining at all. EPCAM expression was significantly less in tumoral tissue than in normal. Conclusion: There was an inverse relationship between tumor staging and the percentage of staining in EPCAM glycoprotein so this marker can be used for predicting the tumor stage.

Background: Peripheral neuropathy is a common complaint of diabetes. This study aimed to determine the effects of 12 weeks combined training with Vitamin D supplement on improvement of sensory-motor neuropathy in women with diabetic neuropathy. Materials and Methods: This clinical trial study conducted on 90 patients were selected and randomly divided into two groups. Finally, 81 adult females with diabetes type II (20–55 years old) were interred in this study. The control group had no training, but received Vitamin D. The experimental group received Vitamin D and 12 weeks training program (3 days a week, 60 min/session) including aerobic exercises, strength, and flexibility. Aerobic exercise intensity was set at 60–70% maximum heart rate and resistance training intensity was determined by 10 R.M. Michigan neuropathy questionnaire, reflex hammer and tuning fork 128 Hz used to screening tense of neuropathy (Michigan Neuropathy Screening Instrument) that were used for pretest and posttest. Results: Following 3 months combined training and supplementation with Vitamin D, had observed a significant reduction in numbness (P = 0.001), pain (0.002), tingling (P = 0.001), and weakness (P = 0.002) in the lower limb and also increases in sense of touch intervention (P = 0.005), detects the position of the fingers (P = 0.001) and vibration perception (P = 0.001) in tissues. Knee reflexes (P = 0.77) and ankles reflexes (P = 0.47) did not significantly change after interventions. Conclusion: It seems that taking part in combined training and supplementation with Vitamin D can improve the symptoms of sensory-motor neuropathy.

Background: Bacterial infections are responsible for great number of mortality in Intensive Care Unit (ICU). Knowledge about prevalence of bacterial infections and their antibiotic-resistance pattern would be a great step for their treatment and management. Materials and Methods: Data about nosocomial infections in ICUs of Alzahra Hospital (referral hospital in Isfahan, center of Iran) were gathered during the years 2007–2010. A questionnaire was fulfilled for any specific patient with nosocomial infection containing demographic data of patient and also characteristics of the infection. Results: Out of all patients, 707 individuals (65.6%) were male and 370 (34.4%) were female. Our data revealed that Pseudomonas aeruginosa (13.9%), Klebsiella (11%), and Escherichia coli (6.4%) were the most prevalent bacterial infections. The most common sites of nosocomial infections in the ICU were respiratory system (399 cases, 37%), urinary system (230 cases, 21.4%), and blood (102 cases, 9.5%). The antibiotic-resistance of each bacteria in ICU ward was assessed and data were categorized in a table. There were less documentary about bacterial cultures in the year 2007 when compared with the next years. Conclusion: We found some differences (such as bacterial prevalence in ICU wards which caused nosocomial infections) in our local prevalence of nosocomial infections and also in their resistance pattern compared to other centers. Knowing about our data will help physicians to administer the most suitable antibiotics for treatment of nosocomial infections in our area.

Background: Insects are mostly pathogens transmitters, thus the necessity of finding effective bioinsecticides to combat them. In the present investigation, the insecticide activity of Ageratina jahnii and Ageratina pichinchensis (Asteraceae) essential oils, methanol, and aqueous extracts was evaluated against Lutzomyia migonei (Diptera: Psychodidae) females, Leishmania transmitters, a wide distributed parasitosis in Latin America. Materials and Methods: All extracts were prepared by maceration at room temperature, and essential oils were obtained by hydrodistillation process. Females of L. migonei were used in the bioassays using the adulticide test in pots. Results: Essential oils from both assayed plant species showed 100% of L. migonei mortality at 48 h of exposure at the concentration of 10 mg/ml. A. jahnii essential oil exhibited the following values, LD₅₀ = 0.39 mg/ml, LD₉₀ = 1.57 mg/ml, LD₉₅ = 2.31 mg/ml, and LD₉₉ = 4.80 mg/ml while for A. pichinchensis essential oil values were LD₅₀ = 0.31 mg/ml, LD₉₀ = 0.99 mg/ml, LD₉₅ = 1.38 mg/ml, and LD₉₉ = 2.55 mg/ml. Conclusion: Higher toxicity was observed with A. pichinchensis essential oil against L. migonei, comparing to A. jahnii oil. Two new plant species are being reported, showing bioactive properties against common tropical disease vectors such as L. migonei, hence, opening possibilities to a more environmental friendly control.

Background: The conventional method for ventilation is supported by accommodative or adaptive support ventilation (ASV) that the latter method is done with two methods: ASV minute ventilation (mv): 110% and ASV mv: 120%. Regarding these methods this study compared the differences in duration of mechanical ventilation and hemodynamic changes during recovery and length of stay in Intensive Care Units (ICU). Materials and Methods: In a clinical trial study, forty patients candidate for ventilation were selected and randomly divided into two groups of A and B. All patients were ventilated by Rafael ventilator. Ventilator parameters were set on ASV mv: 110% or ASV mv: 120% and patients were monitored on pulse oximetry, electrocardiography monitoring, central vein pressure and arterial pressure. Finally, the data entered to computer and analyzed by SPSS software. Results: The time average of connection to ventilator in two groups in modes of ASV mv: 110% and 120% was 12.3 ± 3.66 and 10.8 ± 2.07 days respectively, and according to t-test, there was no significant difference between two groups (P = 0.11). The average of length of stay in ICU in two groups of 110% and 120% was 16.35 ± 3.51 and 15.5 ± 2.62 days respectively, and according to t-test, there found to be no significant difference between two groups (P = 0.41). Conclusion: Using ASV mv: 120% can decrease extubation time compared with ASV mv: 110%. Furthermore, there is not a considerable side effect on hemodynamic of patients.

Background: No previous study exists to evaluate serum phosphorus (Ph) level as a predictor of the need to mechanical ventilation (MV). This study was designed to determine the predictive ability of admission serum Ph level on MV in patients admitted in Intensive Care Unit (ICU). Materials and Methods: This prospective study was conducted on 100 patients (>16 years old), admitted to our ICU over 1-year. Patients were classified into two groups according to the days of the need to MV. Group A: Patients who required equal or <5 days MV, and Group B: Patients who required more than 5 days of MV. We measured total serum Ph concentrations at the times of ICU admission, connecting to the ventilator and weaning from the ventilator. Results: There were significant differences between serum Ph concentration on admission to ICU (Group A: 3.39 ± 0.39 mg/dl, Group B: 2.89 ± 0.31 mg/dl, P < 0.001), at the time of connecting to ventilator (Group A: 2.49 ± 0.38 mg/dl, Group B: 2.25 ± 0.26 mg/dl, P = 0.004) and weaning from ventilator (Group A: 3.42 ± 0.33 mg/dl, Group B: 2.98 ± 0.34 mg/dl, P < 0.001) between two groups. Duration of ICU stay in Group A was 6.08 ± 1.48 days and in Group B was 15.35 ± 6.45, this difference was significant (P < 0.001). We found the best cut-off point of 3.07 for serum Ph concentration to predict the longer duration of MV.Conclusion: According to the results of our study, hypophosphatemia may increase the need to MV. Therefore, monitoring serum Ph level is a good prognostic factor to predict the need to ventilation.

Background: This randomized, parallel-group, non-blinded study was designed to determine the role of fibular fixation in the treatment outcomes of combined distal tibia and fibula fractures. Materials and Methods: Sixty patients with distal tibial and fibular fractures were randomly divided in two groups of case and controls. In the case group, fibula was fixed prior to the fixation of tibia. In the control group, tibia was fixed without fibular fixation. Primary outcomes were varus–valgus angulation, anterior–posterior angulation, union and side effects. Follow-up visit and radiographs were taken 2 and 4 weeks as well as 3, 6 and 9 months after surgery. Results: During the follow-up, 11 out of 60 patients in case and control groups were excluded. We recruited 24 and 25 patients in the case and control group, respectively. Intramedullary nailing was used in 8 patients of case and 11 patients of control group. Plate and screw were used in 16 patients in the case and 14 patients in the control group. Varus/valgus and anterior–posterior angulation were not statistically significant between two groups (P ≥ 0.05). The frequency of tibial and fibula union after 1, 3, 6 and 9 months in case and controls groups were not statistically significant (P ≥ 0.05). The frequency of nonunion of tibia and fibula, infection and nerve injury in studied groups were not statistically significant (P ≥ 0.05). Conclusion: We did not observe any significant improvement using fibular fixation in the treatment outcomes of tibia distal fractures.

Background: This study aimed to determine the prevalence of nonalcoholic fatty liver disease (NAFLD) and its related risk factors among the general population of Isfahan city located in the central part of Iran. Materials and Methods: In this cross-sectional study, the prevalence of NAFLD among 483 general adult populations was determined using ultrasonography. Anthropometric and biochemical variables were compared in groups with and without NAFLD and their predictive value for occurrence of NAFLD was investigated also. Results: Prevalence of NAFLD was 39.3%. Frequency of focal fatty infiltration (FFI), Grade I, Grade II, and Grade III of NAFLD was 9.5%, 21.1%, 7.2%, 1.4%, respectively. Prevalence of different types of NAFLD and FFI, was not different between female and male participants (P = 0.238). Ordinal regression was determined that all of the studied variables have significant predictive value for NAFLD (P < 0.001, γ = 0.615). Spearman correlation indicated that there was a significant relationship between NAFLD and BMI (r = 0.37, P< 0.001), age (r = 0.15, P = 0.001), FBS (r = 0.20, P< 0.001), cholesterol (r = 0.19, P< 0.001), triglyceride (r = 0.20, P< 0.001), LDL (r = 0.16, P< 0.001), AST (r = 0.17, P< 0.001), and ALT (r = 0.31, P< 0.001). Conclusions: Considering the high prevalence of NAFLD specially its lower grades among Isfahani adult general population and their association with studied variables, it seems that interventional studies which target-related mentioned risk factors could reduce the overall occurrence of NAFLD.

The present report describes an acute subdural hematoma (ASDH) associated with subarachnoid hemorrhage (SAH), due to ruptured cortical aneurysm. To our knowledge, extremely rare cases of this sort have been reported so far. A 23-year-old male patient without previous trauma presented with severe headache and rapidly decreasing level of consciousness to decerebrate status. Computed tomography (CT) scan has demonstrated an ASDH together with SAH. Hematoma has immediately been evacuated without any evaluation by angiography. After evacuation of the thick subdural clot, a 10-mm aneurysm was revealed on a precentral artery of frontal cortex, which was ligated. However, after 35 days the patient discharged with left side hemiparesis and dysphasia, and just after several months of admission he got symptom free. Ruptured cortical aneurysm should be considered as one of the causes of spontaneous ASDH. Vascular anomaly investigations are suggested for these cases, thus CT angiography or digital subtraction angiography has to be considered if clinical condition allows.

Background: Hepatitis C infection is one of the health problems in the world. Several known risk factors are responsible in transmission of this infection. We are going to study the prevalence of these risk factors for different genotypes of hepatitis C and if possible, specify probable relations between each risk factor and transmission of each genotype. Materials and Methods: This is a cross-sectional study done on 270 people who had positive anti-hepatitis C virus (HCV) antibody and HCV RNA. Demographic specificity and possible risk factors were collected using a questionnaire, and statistical analysis was done by SPSS software (version 20). Chi-square test used to estimate the prevalence and relation between each qualitative risk factor and HCV genotype transmitted. Analysis of variance was used for studying the prevalence and relation between quantitative risk factors and HCV genotypes. Results: The sample size was 270 persons. Of these, 217 (80.4%) were men and 185 (68.5%) were infected with genotype Type III. Most people were in age range of 31–40 years old 92 (34%). Single people were 126 (46.7%) and 169 (62.6%) were high school and university graduated. Tattooing as a risk factor had a meaningful relation with hepatitis C genotype (P < 0.001). Conclusions: According to the findings, most people in central provinces of Iran with hepatitis C are carrying genotype III, with most prevalent risk factors such as intravenous drug use and unsafe sexual activity. Besides, tattooing had a significant association with hepatitis C genotype, so that in these groups of people, genotype I was more frequent isolated virus.

Background: Migraines are a neurological disease, of which the most common symptom is an intense and disabling episodic headache. Many persons experience sensory hyper excitability manifested by photophobia, phonophobia and osmophobia. This study was planned to investigate the prevalence of osmophobia in migranous and episodic tension type headache (ETTH). Materials and Methods: A semi-structured questionnaire was administered to all patients to evaluate the eventual presence of osmophobia during a headache attack and different characteristics of osmophobia were determined. Results: Osmophobia reported in 84% with migranous headache with aura, 74% of migranous patients without aura and in 43.3% of those with ETTH. In 50% of patients, osmophobia was present in all of their headache attacks, 11.7% had osmophobia in more than half of their attacks (from 10 attacks they reported osmophobia in 5-9 ones) and others had this sign in less than half of their attacks (from 10 attacks they reported osmophobia in less than 5 ones). Most frequently the offending odors were scents (88%), foods (54.2%) and cigarette smoke (62.5%). Osmophobia starts 30 min before the headache starts in 22.7% of patients. Conclusion: Osmophobia appears structurally integrated into the migraine history of the patient; however, for differential diagnosis with ETTH, other criteria are necessary.

Background: Decreased high-energy phosphate level is involved in endothelial cell injury and dysfunction. Reduced telomerase activity in endothelial cells in parallel with reduced energy levels might be due to altered direction of alternative splicing machine as a complication of depleted energy during the process of atherosclerosis. Materials and Methods: Isolated human umbilical vein endothelial cells (HUVECs) were treated for 24 hours by oligomycine (OM) and 2-deoxy glucose (2-DG). After 24 hours, the effect of energy depletion on telomerase splicing pattern was evaluated using RT-PCR. Indeed, in both treated and untargeted cells, nitric oxide (NO) and von Willebrand factor (vWF) were measured. Results: ATP was depleted in treated cells by 43.9% compared with control group. We observed a slight decrease in NO levels (P = 0.09) and vWF (P = 0.395) in the setting of 49.36% ATP depletion. In both groups, no telomerase gene expression was seen. Telomerase and housekeeping gene expression were found in positive control group (colon cancer tissue) and sample tissue. Conclusions: The absence of telomerase gene expression in HUVECs might be due to the mortality of these cells or the low level of telomerase gene expression in these cells under normal circumstances.

Background: One of the major consequences of breast cancer is the recurrence of the disease. The objective of present study was to estimate the 7-year survival without recurrence as well as the effective prognostic factors in recurrence. Materials and Methods: This historical cohort survival analysis was conducted on 1329 patients diagnosed with breast cancer in Motahari Breast Clinic, Shiraz, Iran between 2004 and 2011. We estimated the rate of survival without recurrence through the Kaplan–Meier method and the difference between the survival curves was investigated using the log-rank test. Furthermore, Cox regression model was used to model the effective factors in local recurrence as well as metastasis. Results: The mean age of the patients was 54.8 ± 11.4 years. Estrogen receptor positive, progesterone receptor positive, and human epidermal growth factor receptor-2 positive were observed in 70.6%, 66.6%, and 34.4% of the cases, respectively. The mean of the follow-up period was 3.7 ± 1.8 years in all patients. The results of the Kaplan–Meier method revealed 1-, 3-, 5-, and 7-year rate of survival without recurrence as 96.4%, 78.4%, 66.3%, and 54.8%, respectively. There was a significant relationship between survival without recurrence and histology grade (hazard ratio [HR] = 1.66, P = 0.009), neural invasion (HR = 1.74, P = 0.006), and progesterone receptors (HR = 0.69, P = 0.031). Conclusion: In this study, the rate of survival without recurrence in breast cancer was 54.8%. Among factors, histology grade and neural involvement at the time of diagnosis increased the chance of recurrence and progesterone receptors caused a longer interval between diagnosis and recurrence.

Background: Multi-drug resistant Klebsiella pneumoniae has been considered as a serious global threat. This study was done to investigate carbapenemase producing genomes among K. pneumoniae isolates in Isfahan, Central Iran. Materials and Methods: In a cross-sectional study from 2011 to 2012, 29 carbapenem resistant (according to disc diffusion method) carbapenemase producing (according to modified Hodge test) K. pneumoniae strains were collected from Intensive Care Unit (ICUs) of Al-Zahra referral Hospital. In the strains with the lack of sensitivity to one or several carbapenems, beta-lactams, or beta-lactamases, there has been performed modified Hodge test to investigate carbapenmase and then only strains producing carbapenmases were selected for molecular methods. Results: In this study, there have been 29 cases of K. pneumoniae isolated from hospitalized patients in the (ICU). Three cases (10.3%) contained blaVIM, 1 case (3.4%) contained blaIMP, and 1 case (3.4%) contained blaOXA. The genes blaNDM and blaKPC were not detected. Then, 16 cases (55.2%) from positive cases of K. pneumoniae were related to the chip, 4 cases (13.8%) to catheter, 6 cases (20.7%) to urine, and 3 cases (10.3%) to wound. Conclusion: It is necessary to monitor the epidemiologic changes of these carbapenemase genes in K. pneumoniae in our Hospital. More attention should be paid to nosocomial infection control measures. Other carbapenemase producing genes should be investigated.

Background: This study was designed to evaluate the effect of melatonin on nonalcoholic fatty liver disease (NAFLD) in compared to placebo. Materials and Methods: A total of 100 patients with histopathological diagnosis NAFLD in two groups of case and control received oral melatonin or placebo thrice daily for 3 months. Collected data were weight, waist, systolic blood pressure (SBP), diastolic blood pressure (DBP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), high sensitive C-reactive protein (hsCRP), fatty liver grade, and side effects which were measured at baseline and after treatment period using standard clinical chemistry techniques. Results: Before treatment the mean of weight, waist, SBP, DBP, ALT, AST, and hsCRP between cases and controls were similar (P > 0.5). After treatment, only the differences in the mean of hsCRP in cases was significantly lower than controls (P = 0.003). In case group, all variables after treatment were significantly decreased compare to baseline (P > 0.5) and only AST after treatment was similar to before treatment (P > 0.5). The mean of a decrease in the level of weight, waist, SBP, and ALT were not statistically significant between groups (P > 0.5). In the case group in compare to control group the level of DBP, AST, and hsCRP significantly more decreased. After treatment fatty, liver grade was statistically improved in more cases than controls (P = 0.001). Side effects were similar between the two groups. Conclusion: Melatonin significantly decreases liver enzymes, so the use of melatonin in patients with NAFLD can be effective.

Background: The aim of the current study was to determine mast cell infiltration in malignant melanoma by immunohistochemistry method and its relationship with some of the cancer prognostic factors, including age, sex, and depth of the tumor. Materials and Methods: In this retrospective analytic cross-sectional study, paraffin-embedded tissue blocks of patients with cutaneous malignant melanoma who had undergone excisional biopsy were studied. Mast cells count in studied cases in different stages of the tumor depth was evaluated by mast cell tryptase immunohistochemistry method. Mast cells infiltration was evaluated both inside the tumor and peritumoral area. Tumor infiltrating lymphocytes (TILs) was also determined. Distribution of intratumoral and peritumoral mast cells and TILs was compared in different stages tof tumor depth. Results: In this study, 51 cases with melanoma were studied. Mean ± standard deviation (SD) of intratumoral mast cells in stages 1, 2, and 3 was 9.4 ± 4.2, 10.8 ± 5.1, and 2.1 ± 2.3, respectively (P = 0.000). Mean ± SD of peritumoral mast cells in stages 1, 2 and 3 was 13.4 ± 2.4, 16.6 ± 2.4 and 8.2 ± 4.6, respectively (P = 0.000). There was a significant direct relationship between depth of the tumor and TIL (P = 0.000) and distribution of intratumoral (P = 0.000) and peritumoral mast cells (P = 0.000). Conclusion: Lower distribution of intratumoral and peritumoral mast cells and TILs in higher stages of tumor depth in malignant melanoma suggests a possible inhibitory effect of infiltrating mast cells and lymphocytes on the progression of this tumor.

Background: Suicide is a major problem, and its prevention is a global priority. In many cases, suicide attempter attempts to do it again after the rescue. In current study we aimed to compare active visit and treatment of patients in a periodic manner with treatment as usual, in the prevention of recurrent suicidal attempts. Materials and Methods: This study was a randomized controlled clinical trial which was conducted in Isfahan Noor Hospital's Emergency Center on 60 patients in 2013-2014. The samples were selected using simple random sampling and they were assigned into two groups: The conventional treatment group (treatment as usual) (30 patients), and visit and active treatment (30 patients). In the intervention group, there were ten follow-ups by a face-to-face visit over 12 months, and six follow-ups by phone call in control group. Through the completion of the initial and follow-up questionnaire evaluation was performed. The data were analyzed using Cochran test, and repeated measure (ANOVA). Results: During the 12-month follow-up visit and active treatment, significant difference in reducing suicidal thoughts (P = 0.003) was observed and an increase in the life expectancy (P = 0.001), interest and motivation in life (P = 0.001) was found in the intervention group, and also nonsignificant reduction was found in the rate of suicidal attempts. Conclusion: Visit and active treatment is useful in suicide attempters and it can helps in preventing recurrent suicide attempt as a preventive program by increasing hope and reducing suicidal thoughts.

Background: The estimated incidence and prevalence of tuberculosis in India are 2.1 and 2.6 million cases respectively. Immunotherapy may shorten tuberculosis treatments and improve the immunity of individuals as well. Hence we study the efficacy of levamisole (LVM) (immunomodulator) as an adjuvant to chemotherapy of pulmonary tuberculosis patients. Materials and Methods: A randomized, double-blind, placebo-controlled clinical trial was conducted for 21 months in newly diagnosed sputum positive pulmonary tuberculosis patients. Patients were subjected initially to clinical examination, sputum acid-fast bacilli smear and culture, tuberculin skin test and weight record. During follow-up, above investigations were repeated. Sixty-five patients were randomly assigned into two groups to receive either tab LVM 100 mg once in a day or matching placebo, orally as a single dose, thrice a week, for 2 months with short-course antituberculosis chemotherapy. Results: Sputum negativity at 1 week was observed in 11 (44%) patients in LVM group whereas only 3 (12%) in placebo group. All the patients 25 (100%) in LVM group were sputum negative compared to 14 (56%) in placebo group by the end of 3 weeks. In LVM group, 24 (96%) and 11 (44%) patients in placebo group show radiological improvement at 2 months. A direct correlation existed between quantum of immune response and weight gain with LVM. LVM rendered all anergic patients to positive tuberculin reactors. In LVM group, patients with initial Mantoux ≥20 mm and advanced cavitary disease, there was decrease in tuberculin reaction size. Conclusion: Adjuvant immunomodulation with levamisole has the potential of shortening the total duration of antitubercular therapy.

Background: Identification of osteoporosis in women in order to prevent its related morbidity and mortality is considered a priority. Routine mammography is performed on all menopausal women as a screening tool. Determination of the relation between breast arterial calcification (BAC) on mammography and the bone density of this high-risk population could help us to determine those with osteoporosis. The aim of this study was to investigate the mentioned probable relation between BAC and osteoporosis. Materials and Methods: In this cross-sectional study, menopausal women referred for annual screening mammography were enrolled. According to the results of mammography, they were classified into two groups: menopausal women with and without calcification of breast arteries. The selected women were referred for bone mineral density (BMD) evaluation by dual-energy x-ray absorptiometry (DXA). The results of BMD were compared between the two studied groups. Results: In this study, BMD was measured in 43 and 45 menopausal women with and without BAC, respectively. After age adjustment the difference between BMD measurements were not statistically significantly different (P > 0.05). There was a significant negative correlation between age and lumbar (P = 0.002, r = -0.42) and hip bone (P = 0.000, r = -0.67) density in menopausal women with BAC. Conclusion: The results of the current study indicated that there was no significant relationship between BAC and BMD in our studied population, but it seems that increasing age has an important role in both developing BAC and reducing BMD. For obtaining more conclusive results, further studies with larger sample sizes and considering the severity of BAC is recommended.

Background: The aim of this study is the caparison of the complications rate among the patients which underwent nephrostomy removal with and without performing nephrostography. Materials and Methods: Between October 2010 and November 2011, 200 patients who underwent standard percutaneous nephrolithotomy (PCNL) procedures were included in this study. The patients were randomly assigned into two groups, Group A (n = 100) did not undergo the antegrade nephrostography on postoperative day 2 and the patients were discharged keeping the nephrostomy until postoperative day 3, while in Group B (n = 100) the nephrostomy tube was removed on postoperative day 3 after antegrade nephrostography demonstrating ureteral drainage down to the bladder. Postoperative complications in both groups were recorded and compared between two groups. Results: A total of 200 patients were treated with standard PCNL. The persistent leakage of urine after removal of the nephrostomy tube was encountered in 5 (5.0%) and 3 (3%) of patients in Groups 1 and 2, respectively. Urinary leakage was resolved with conservative management in 3 and 2 patients of Groups 1 and 2, respectively, but a double-J stent was inserted in 2 and 1 patients in each group because of persistent leakage of urine more than 1-week. The two groups show comparable complications such as prolonged urinary leakage which managed in a similar manner, however, postoperative hospital stay was lesser in Group 1. Conclusion: Our results revealed postoperative performing nephrostogramy before tube removal changed the planning of complications such as prolonged urinary leakage and could be omitted in cases.

Background: Vitiligo, a common disorder of depigmentation, is often difficult to treat. Corticosteroids are known to be effective, but with modest results. Although simvastatin has been reported to be effective for immunorelated dermatologic disorders including vitiligo, controlled trials are lacking. This study was conducted to compare the efficacy of topical betamethasone valerate 0.1% cream (as a standard method of treatment for vitiligo) versus a combination of betamethasone valerate plus oral simvastatin in the treatment of vitiligo. Materials and Methods: Eighty-eight subjects with symmetric vitiligo who had body surface involvement up to 20% were divided randomly into two groups. Group A were treated with betamethasone valerate 01% cream twice daily and Group B with betamethasone valerate 01% cream twice daily and oral simvastatin 80 mg daily for 12 weeks. Finally, 46 patients completed treatment after 12 weeks in both groups. The results were evaluated by a blind dermatologist using Vitiligo Area Scoring Index (VASI) score at baseline, 4^th, 8^th, and 12^th week of treatment. In a similar way, subjective assessment performed by patients based on photo evaluation at the end of the study. Results: Despite a continuous reduction in VASI score in both groups, according to both physician (P = 0.13) and patient (P = 0.374) assessment oral simvastatin was not statistically more effective than conventional treatment of vitiligo. Conclusion: This study indicates that oral simvastatin is not associated with significant impacts in the treatment of vitiligo as compared to other inflammatory dermatologic conditions such as psoriasis. Indeed, other studies should be initiated regarding exact molecular and cellular effects of statins in the treatment of vitiligo.

Background: Y chromosome is one of the two sex chromosomes and is male specific. Due to limited genetic exchange, the main part of that is passed virtually unchanged from one generation to next generation. The short tandem repeats (STRs) are almost constant on chromosomes that make them as an appropriate factor for use in population genetic studies. In this study, we used the STRs of Y chromosome markers in Sadat families and comparison with other families was investigated. Materials and Methods: In this study, sampling was done from fifty unrelated males of Sadat families and fifty unrelated males of non-Sadat families. After the extraction of DNA from blood samples and primer design, polymerase chain reaction (PCR) was performed for each primer pairs separately. The PCR products were run on agarose gel that followed by running on polyacrylamide gel for better resolution. In addition, some sequenced samples were used as identified markers to determine the length of other alleles in polyacrylamide gel. Results: The survey of six STR in two case and control groups was carried out, and analysis revealed that the frequency of some alleles is different in case group compared to control group. Allele frequency of the markers DYS392, DYS393, DYS19, DYS390, DYS388, and DYS437 on the Y chromosome in Sadat families was quite different in comparison with other families. Conclusions: The reason for these differences in allele frequencies of the Sadat family in comparison with other families is having a common ancestor.

Background: Mutations in different genes including dystrophin-associated glycoprotein complex caused familial dilated cardiomyopathy which is a genetically heterogeneous disease. The δ-SG gene contains nine exons spanning a 433-kb region of genomic DNA. It encodes a 35-kDa, singlepass, and type II transmembrane glycoprotein. Materials and Methods: In this study for the first time in Iran we screened 6 patients of a large family that they had positive family history of MI or sudden death by next generation sequencing method. Results: By employing NGS method we found missense mutation (p.R97Q) of δ-SG gene in 2 of 6 patients. Conclusions: The missense mutation (p.R97Q) in familial DCM patients is reported for the first time in Iranian patients with cardiac disease. Although this mutation is already known in other populations in Iran, it is not reported before.

Probiotics or health-beneficial bacteria have only recently been introduced in dentistry after years of successful use in mainly gastrointestinal disorders. The concept of bacteriotherapy was first introduced in the beginning of 20^th century. They are administered in different quantities that allow for colon colonization. These products help in stimulating health promoting flora and also suppressing the pathologic colonization and disease spread. The use of probiotic plays an important aspect in dentistry too, ever since the oral infections occupied the prime spot among the other infections affecting the humans. Probiotics strengthen the immune system to combat allergies, stress, exposure to toxic substances, and other diseases. This review is an attempt to discuss briefly the role of probiotics in oral health.

Background: Refractory or relapsed Hodgkin's disease (HD) occurs in 10-50% of patients. The treatment of choice for these patients is high-dose chemotherapy (HDCT) and autologous stem cell transplantation (ASCT). Response to salvage chemotherapy (SCT) partial remission (PR) is necessary before HDCT with ASCT. However, its applicability is restricted mostly to patients responding to salvage chemotherapy. Optimal salvage regimen for these patients is unclear. In this study, our aim was to compare the efficacy profiles of ifosfamide, carboplatin, and etoposide (ICE) and etoposide-steroid-cytarabine-cisplatin (ESHAP) (cytosine arabinoside, cisplatin, and dexamethasone) regimens in the salvage treatment of relapsed or refractory HD. Materials and Methods: In this retrospective analysis, 114 patients with primary refractory or relapsed HD who received ICE or ESHAP salvage regimen were included. Results: Of 114 patients, 47 (41.2%) were females and the median age was 31.5 years. Response could be evaluated in 114 patients. Of 114 patients, 38 (33%) achieved complete remission (CR) and 21 (18.4%) achieved PR, leading to an overall response rate (ORR: CR + PR) of 51.4%. In the evaluable ICE group (n = 41), rates of CR, PR, and ORR were 21.9%, 17.1%, and 39% and in the ESHAP group (n = 73), rates of CR, PR, and ORR were 39.7%, 19.2%, and 58.9% (for ORR,P = 0.04), respectively. Conclusion: In patients with relapsed or refractory HD, treatment with ESHAP seems to have higher rates of response than ICE regimen does.

Placental site throphoblastic tumor (PSTT) is a rare manifestation of gestational trophoblastic neoplasia that may complicate any type of pregnancy. The disease is unique from other type, and is defined by slow growth, low human chorionic gonadotropin (hCG) serum levels, the late-onset metastatic potential, and most significantly, insensitivity to chemotherapy. We describe a case of a 31-year-old woman with prolonged amenorrhea and slightly elevated serum beta hCG (βhCG) level, referred for termination of abnormal pregnancy. During curettage, necrotic tissue was removed and severs vaginal bleeding was controlled with medical therapy. Histology examination showed neoplastic intermediate trophoblastic cells with invasion to the vessel wall compatible with PSTT. After that, hysterectomy was down and serum βhCG declined to undetectable level 2 weeks after surgery and was followed for 2 years without complication.

Background: Remote ischemic preconditioning (RIPC) is a phenomenon where a short period of ischemia in one organ protects against further ischemia in the other organs. We hypothesized that RIPC occurring in diabetic patients with ankle brachial index (ABI) between 0.70 and 0.90 were included with peripheral arterial disease, would make the better coronary flow resulted in the increasing ABI. Materials and Methods: This randomized clinical trial study was done in the Afshar Cardiovascular Hospital in Yazd between 2013 and 2014. Sixty participants were randomly divided into two groups (intervention and control groups). The intervention group was undergoing RIPC, and the control group was tested without RIPC. RIPC was stimulated by giving three cycles of 5 min of ischemia followed by 5 min of reperfusion of both upper arms using a blood pressure cuff inflated to 200 mm Hg (n = 30). This was compared with no RIPC group which consisted of placing a deflated blood pressure cuff on the upper limbs (n = 30). Results: The mean of ABI level before intervention in the RIPC and control group group was 0.82 ± 0.055 and 0.83 ± 0.0603 (P = 0.347) respectively, with no significant difference. It was 0.86 ± 0.066 in the RIPC group compared the control 0.83 ± 0.0603 (P = 0.046). So levels of ABI were greater after intervention in the RIPC group. The mean of ABI level increase from 0.82 ± 0.05 to 0.86 ± 0.06 in RIPC group (P = 0.008). So the intervention group showed a significant increase in ABI. Conclusions: RIPC through using a simple, noninvasive technique, composing three cycles of 5 min-ischemia of both upper arms, showing a significant increase in ABI level in diabetic patients.

Proteus syndrome is a rare sporadic disorder that appears with localized macrosomia, congenital lipomatosis, and slow flow vascular malformations, connective tissue nevus, and epidermal nevus. There are usually some manifestations at birth. The vascular abnormalities that have been reported in Proteus syndrome are capillary and slow flow venous malformation. We report a case of a 10-year-old boy with confirmed Proteus syndrome characterized by high flow vascular malformation (arteriovenous [AV] malformation) unlike the usual vascular malformations seen in this syndrome. This case adds a new perspective to the established clinical findings of the Proteus syndrome.

Background: Anaphase promoting complex (APC) is the biggest Cullin-RING E3 ligase and is very important in cell cycle control; many anti-cancer agents target this. APC controls the onset of chromosome separation and mitotic exit through securin and cyclin B degradation, respectively. Its APC3 subunit identifies the APC activators-Cdh1 and Cdc20. Materials and Methods: The structural model of the APC3 subunit of APC was developed by means of computational techniques; the binding of a natural inhibitory compound to APC3 was also investigated. Results: It was found that APC3 structure consists of numerous helices organized in anti-parallel and the overall model is superhelical of tetratrico-peptide repeat (TPR) domains. Furthermore, binding pocket of the natural inhibitory compound as APC3 inhibitor was shown. Conclusion: The findings are beneficial to understand the mechanism of the APC activation and design inhibitory compounds.

Background: Valproic acid (VPA) is a widely used broad-spectrum antiepileptic drug for therapy of generalized and focal epilepsies. Cross-sectional studies have suggested that valproate treatment may be associated with hyperinsulinemia. We decided to investigate hyperinsulinemia as a health-threatening side effect of VPA in Iranian epileptic patients. Materials and Methods: Body mass index (BMI), lipid profile, fasting serum insulin, fasting blood glucose (FBS), and homeostatic model assessment-insulin resistance (HOMA-IR) were measured in 30 VPA-treated epileptic patients and 30 controls (CBZ-treated). The Chi-square test, t-test, and Pearson correlation test were used. Results: BMI was higher in VPA group than in control group (25.7 ± 3.5 > 21.7 ± 4.1) (0.000 < 0.05). Prevalence of obesity was 16.6% in VPA group that was almost the same and even lower than general Iranian population. Serum triglyceride (TG) (150 ± 77.2) was higher than CBZ group (114 ± 35.2) (P = 0.023 < 0.05). However, serum high-density lipoprotein level was lower in VPA group than controls (45.2 ± 11.7 < 54.4 ± 13.9) (P = 0.008 < 0.05). Serum insulin, FBS, HOMA-IR, cholesterol, and low-density lipoprotein did not demonstrate statistically significant differences between the two groups (P > 0.05). Conclusion: Despite the majority of previous studies that are against VPA and according to our study, VPA could be prescribed safely and it may not cause IR and its complications.

Background: Metabolic syndrome (MetS) is a common disorder which is a constellation of clinical features including abdominal obesity, increased level of serum triglycerides (TGs) and decrease of serum high-density lipoprotein-cholesterol (HDL-C), elevated blood pressure, and glucose intolerance. The apolipoprotein A5 (APOA5) is involved in lipid metabolism, influencing the level of plasma TG and HDL-C. In the present study, we aimed to investigate the associations between four INDEL variants of APOA5 gene and the MetS risk. Materials and Methods: In this case–control study, we genotyped 116 Iranian children and adolescents with/without MetS by using Sanger sequencing method for these INDELs. Then, we explored the association of INDELs with MetS risk and their clinical components by logistic regression and one-way analysis of variance analyses. Results: We identified a novel insertion polymorphism, c. *282–283 insAG/c. *282–283 insG variant, which appears among case and control groups. rs72525532 showed a significant difference for TG levels between various genotype groups. In addition, there were significant associations between newly identified single-nucleotide polymorphism (SNP) and rs72525532 with MetS risk. Conclusions: These results show that rs72525532 and the newly identified SNP may influence the susceptibility of the individuals to MetS.

Background: Thalassemias are the most common monogenic disorders in many countries throughout the world. The best practice to control the prevalence of the disease is prenatal diagnosis (PND) services. Extensive practicing of PND proved effective in reducing new cases but on the other side of this success high abortion rate is hided, which ethically unfair and for many couples, especially with a previous experience of a therapeutic abortion, or moral concerns, is not a suitable choice. Preimplantation genetic diagnosis (PGD) is a strong alternative to conventional PND. At present PGD is the only abortion free fetal diagnostic process. Considering the fact that there are more than 6000 single gene disorders affecting approximately 1 in 300 live-births, the medical need for PGD services is significant. Materials and Methods: In the present study development of a PGD protocol for a thalassemia trait couple using nested multiplex fluorescent polymerase chain reaction (PCR) for the combination of polymorphic linked short tandem repeat (STR) markers and thalassemia mutations is described. Restriction fragment length polymorphism used to discriminate between wild and mutated alleles. Results: In PGD clinical cycle, paternal and maternal alleles for D11S988 and D11S1338 STR markers were segregated as it was expected. PCR product for IVSII-1 mutation was subsequently digested with BtscI restriction enzyme to differentiate normal allele from the mutant allele. The mother's mutation, being a comparatively large deletion, was detectable through size differences on agarose gel. Conclusion: The optimized single cell protocol developed and evaluated in this study is a feasible approach for preimplantation diagnosis of β-thalassemia in our patients.

Background: The aim of this study was to determine the best condition for the production of DT386-BR2 fusion protein, an immunotoxin consisting of catalytic and translocation domains of diphtheria toxin fused to BR2, a cancer specific cell penetrating peptide, for targeted eradication of cancer cells, in terms of the host, cultivation condition, and culture medium. Materials and Methods: Recombinant pET28a vector containing the codons optimized for the expression of the DT386-BR2 gene was transformed to different strains of Escherichia coli (E. coli BL21 DE3, E. coli Rosetta DE3 and E. coli Rosetta-gami 2 DE3), followed by the induction of expression using 1 mM IPTG. Then, the strain with the highest ability to produce recombinant protein was selected and used to determine the best expression condition using response surface methodology (RSM). Finally, the best culture medium was selected. Results: Densitometry analysis of sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the expressed fusion protein showed that E. coli Rosetta DE3 produced the highest amounts of the recombinant fusion protein when quantified by 1 mg/ml bovine serum albumin (178.07 μg/ml). Results of RSM also showed the best condition for the production of the recombinant fusion protein was induction with 1 mM IPTG for 2 h at 37°C. Finally, it was established that terrific broth could produce higher amounts of the fusion protein when compared to other culture media. Conclusion: In this study, we expressed the recombinant DT386-BR2 fusion protein in large amounts by optimizing the expression host, cultivation condition, and culture medium. This fusion protein will be subjected to purification and evaluation of its cytotoxic effects in future studies.

Background: The aim of this study is to find a pathway to explaining the relations between dietary behaviors with mental health and psychological functioning. Materials and Methods: This cross-sectional study contains 4763 participants from the employees of Isfahan University of Medical Sciences. In this study, four questionnaires were administered which were provided as follows: demographic characteristics, 21-item dietary behaviors questionnaire, Hospital Anxiety and Depression Scale questionnaire, and 12-item General Health Questionnaire (GHQ-12). We started the analysis with the structural equation modeling (SEM) model with 4 unobserved latent and 16 observed variables. Results: The results show that the regression coefficient (standard error) of diet behavior on mental health and mental health on GHQ were − 1 (0.37) and 0.02 (0.01) with their P values as 0.007 and 0.01, respectively. For this model, the estimated root mean square error of approximation is 0.062 with 90% confidence interval of (0.060–0.065). In addition, the comparative fit indices (CFIs) were as 0.866 for incremental fit index and 0.866 for CFI. All these indices represent fairly good fit of the model to the data. Conclusion: We can conclude that “lower scores on diet behavior – higher scores on mental health problems” and “higher mean scores in depression and/or anxiety – higher scores in GHQ domains.” The SEM results showed that dietary behaviors have significance related to depression and/or anxiety and general health status.

Background: Acne is a very common skin disease in which scars are seen in 95% of the patients. Although numerous treatments have been recommended, researchers are still searching for a single modality to treat the complication due to its variety in shape and depth. We compared the effects of fractional carbon dioxide (CO₂) laser alone and in combination with subcision in the treatment of atrophic acne scars. Materials and Methods: This clinical trial study was performed in Skin Diseases and Leishmaniasis Research Center (Isfahan, Iran) during 2011–2012. Eligible patients with atrophic acne scars were treated with fractional CO₂laser alone (five sessions with 3-week interval) on the right side of the face and fractional CO₂laser plus subcision (one session using both with four sessions of fractional CO₂laser, with 3-week interval) on the left side. The subjects were visited 1, 2, and 6 months after the treatment. Patient satisfaction rate was analyzed using SPSS 20 software. Results: The average of recovery rate was 54.7% using the combination method and 43.0% using laser alone (P < 0.001). The mean patient satisfaction was significantly higher with the combination method than laser alone (6.6 ± 1.2 vs. 5.2 ± 1.8; P < 0.001). Bruising was only seen with the combination method and lasted for 1 week in 57.0% and for 2 weeks in 43.0%. Erythema was seen in both methods. Postinflammatory pigmentation and hyperpigmentation were associated with combination method. No persistent side effects were seen after 6 months. Conclusion: Using a combination of subcision and laser had suitable results regarding scar recovery and satisfaction rate.

Background: Pedicle screw instrumentation has many advantages for correction of adolescent idiopathic scoliosis (AIS) deformity including better correction and fewer late complications. On the other hand, screw insertion in AIS is challenging. Intraoperative fluoroscopy or navigation techniques are expensive, time-consuming, and exposed to high radiation. Free-hand technique relies on the surgeon's experience and locating the pedicle entry point with anatomical landmarks. There are few studies that evaluated pedicle screw position accuracy with postoperative multi-slice computed tomography scan. Materials and Methods: We prospectively considered 38 consecutive AIS cases, who underwent corrective surgery with all pedicle screw technique. All the screws were inserted with free-hand technique using anatomic landmarks as a guide for an entry site. We divided pedicle penetration in medial, lateral, inferior, superior, and anterior vertebral body as Grades 0–4, that Grade 0 is fully contained within the pedicle, Grade 1 (<2 mm), Grade 2 (2.1–4 mm), Grade 3 (4.1–6 mm), and Grade 4 (>6 mm). Results: A total of 720 screws were inserted, of which 623 screws (86.5%) were perfect and 97 screws (13.5%) were misplaced. Of those which were misplaced, 39 screws (40.2%) were medial and 58 (59.8%) were lateral, which shows that the prevalence of lateral misplacement was more in comparison to medial misplacement. However, in all misplaced cases, the deviation of the screw was <2 mm (Grade 1). There was no misplacement in the inferior and superior. Conclusion: Pedicle screw insertion in AIS with the free-hand technique is a safe and reliable method.

Background: Fistulas are the preferred permanent hemodialysis vascular access, but a significant obstacle to increasing their prevalence is the fistula's high “failure to mature” (FTM) rate. This study aimed to identify postoperative clinical characteristics that are predictive of fistula FTM. Materials and Methods: This descriptive cross-sectional study was performed on 80 end-stage renal disease patients who referred to Al Zahra Hospital, Isfahan, for brachiocephalic fistula placement. After 4 weeks, the clinical criteria (trill, firmness, vein length, and venous engorgement) examined and the fistulas situation divided to favorable or unfavorable by each criterion, and the results comprised with dialysis possibility. Data were analyzed with SPSS version 21. Diagnostic index for CLINICAL examination was calculated. Results: Among the 80 cases, 25 (31.2%) female and 55 (68.8%) male were studied with the mean age of 51.9 (standard deviation = 17) year ranged between 18 and 86 years old. Sixty-two (77.5%) cases had successful hemodialysis. All four clinical assessments were significantly more acceptable in patients with successful dialysis (P < 0.001). According to the results of our study, the accuracy of all physical assessments was above 70% and except vein length other criteria had a sensitivity and negative predictive value of 100%. In this study, firmness of vein has highest specificity and positive predictive value (83.9% and 64.3%, respectively). Conclusion: Results of our study showed that high sensitivity and relatively low specificity of the clinical criterion. It means that unfavorable results of each clinical criterion predict unfavorable dialysis. Clinical evaluation of a newly created fistula 4–6 weeks after surgery should be considered mandatory.

Background: Resistance of Leishmania species to antimonial drugs has increased. Hence, in the present study Leishmania major isolates were collected from patients with resistance phenotype and the presence/absence of resistance to Glucantime was investigated. Materials and Methods: Samples were taken from 10 cutaneous leishmaniasis (CL) patients who had not responded to chemotherapy with Glucantime. Nested polymerase chain reaction (PCR) was performed to identify the isolated species. Stationary phase promastigotes were added to the grown, adhesive J774 macrophages. Values obtained from standard strain were compared with the test cultures after exposure to the medicine. In vivo, the effects of Glucantime were assessed by comparing the sizes and the parasite burden of the lesions on mouse model. Results: The results of amplified band on agarose gel demonstrated all samples were L. major. After exposure to medicine, a reduction of intracellular amastigotes to half was detected. In vivo, the parasite was eliminated in 90% of mice with lesions caused by both isolates of patients and standard L. major, and their lesions became smaller significantly. Conclusion: Pentavalent antimonial (SbV) salts are the main component of chemotherapy against leishmaniasis. However, the medicine has been found ineffective. In the present study, isolates from patients with no response to treatment had no significant difference from the standard L. major strain (as the sensitive strain). Therefore, in patients with resistance phenotype to Glucantime, the parasites did not actually have intrinsic resistance, i.e., environmental and host factors prevented the successful treatment of the disease.

We report a case of malignant transformation of an intracranial extradural epidermoid cyst into squamous cell carcinoma (SCC), that presented with cerebrospinal fluid (CSF) leakage at the time of recurrence. Intracranial epidermoid cysts are histologically benign and slow-growing neoplasms. They are congenital lesions that develop from ectodermal remnants during neuroembryogenesis. Malignant transformation of epidermoid cysts into SCC is very rare. Various clinical presentations of these tumors after malignant transformation are mentioned in the literature. None of the previous cases, presented with CSF leakage as the recent case did. In cases of malignant transformation, surgical resection and then adjuvant radiation therapy are highly recommended.

Background: Selection of stably expressing housekeeping genes (HKGs) is a crucial step in gene expression analysis. However, there are no universal HKGs for all experiments, and they should be determined by each biologic condition. The aim of this study was to detect appropriate HKGs for kidney cells cultured in long-term hypoxia. Materials and Methods: Based on a screening step using a microarray data available from gene expression omnibus database, a set of candidate HKGs were chosen to be assessed in human kidney cells cultured in hypoxic or normoxic conditions for about 2 weeks in a time course manner. The stability of gene expression was assessed by refFinder, a web-based tool that integrates four computational programs (geNorm, Normfinder, BestKeeper, and the comparative ΔΔCt method). Results: GAPDH and ACTB were the most stable genes in hypoxia treated cells whereas, B2M and ACTB were the best HKGs in cells cultured in normoxia. When both hypoxia and normoxia treated cells from all time points were evaluated together, GAPDH and ACTB equally showed the most stability. Conclusion: As in relative quantification of real-time polymerase chain reaction data, the same HKGs should be selected for all groups, we believe that GAPDH and ACTB are suitable HKGs for studies on the effect of hypoxia on cultured kidney cells.

Background: Features of malignant melanoma (MM) vary in the different geographic regions of the world. This may be attributable to environmental, ethnic, and genetic factors. The aim of this study was to determine the expression of estrogen receptor alpha (ER-α) in MM in Isfahan, Iran. Materials and Methods: This study was planned as a descriptive, analytical, cross-sectional investigation. During this study, paraffin-embedded tissue blocks of patients with a histopathologic diagnosis of MM was studied for ER-α using immunohistochemistry (IHC). Results: In this study, 38 patients (female/male; 20/18) with a definite diagnosis of malignant cutaneous melanoma and mean age of 52.4 ± 11.2 years were investigated. Using envision IHC staining, there were not any cases with ER-α expression. Conclusion: In confirmation to the most previous studies, expression of ER-α was negative in MM. It is recommended to investigate the expression of estrogen receptor beta and other markers in MM.

Background: Recently, the relationship between increased level of inflammatory mediators and occurrence of left ventricular failure in patients with kidney disease has been suggested. The present study attempted to assess relationship between inflammatory mediators and occurrence of left ventricular failure in patients with chronic kidney disease. Materials and Methods: This cross-sectional study was performed at Noor and Hazrat Aliasghar hospital in Isfahan between September 2012 to September 2013 on patients aged >19 years that referred for following their chronic kidney disease. Serum level of inflammatory parameters including C-reactive protein (CRP) and Interleukin-6 (IL-6) was measured using spectrophotometer. All patients were also assessed using M-mode echocardiography to determine left ventricular ejection fraction (LVEF). Results: The group with significant reduced LVEF showed lower GFR when compared to the normal LVEF group (40.73 ± 20.61% versus 44.43 ± 17.98%, P = 0.032). Comparing GFR across the three groups with normal LVEF >55%), with mild LV dysfunction (LVEF: 45 – 55) those with significant LV dysfunction (LVEF < 45%) showed significantly lower GFR level in latter group compared with normal LVEF and mild LV dysfunction group (P = 0.026). Although the level of serum CRP was significantly higher in patients with significant left ventricular failure than other groups (P = 0.018). Conclusion: Inflammatory processes can potentially affect left ventricular function in patients with chronic kidney disease. In this regard, increased level of CRP may be a main factor for predicting severity of left ventricular failure in these patients.

Background: Nonalcoholic fatty liver disease (NAFLD), defined as excessive liver fat deposition and one of end-stage liver disease causes. Increased ferritin levels are associated with insulin resistance and a higher hepatic iron and fat content. Hyperferritinemia has been associated with severity of liver damage in NAFLD. The study aimed to evaluate the effects of phlebotomy on liver enzymes and histology in such patients. Materials and Methods: Thirty-two eligible patients who had NAFLD and after 6 months of lifestyle modification still had NAFLD, and whose ferritin serum was above 250 mg/dl, were enrolled in this clinical trial study. After written informed consent was obtained, each patient's blood serum was taken for aspartate transaminase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALK-P), complete blood count (CBC), total iron-binding capacity (TIBC), iron, and ferritin. Then the patients underwent liver biopsy. After that patients underwent phlebotomy, giving 350 cc blood monthly. Before every phlebotomy, hemoglobin and ferritin were checked. If they were in the goal range, phlebotomy was discontinued and the patient underwent liver biopsy. A serum sample was taken for testing at the beginning of the study. The results before and after phlebotomy were compared. The maximum duration of the study was 6 months. Results: Thirty-two patients (26 males and 6 females) were enrolled, and the mean average age was 33.7 ± 6.74 years. Phlebotomy improved liver enzymes and histology of liver significantly (P < 0.001) and induced reduction of ferritin. Conclusion: Phlebotomy is effective for the improvement of liver enzymes and histology in patients with NAFLD and hyperferritinemia.

Background: This study was designed to investigating the effect of combining D-cycloserine (DCS) and cognitive-behavioral therapy (CBT) on adolescent with at least one type of anxiety disorders. Materials and Methods: The present study was conducted as a double-blind randomized controlled trial on 36 adolescent with anxiety disorders. Patients were assessed in two groups. In addition to 4 sessions of weekly CBT in both groups; case group, received a 50-mg DCS capsules, control group, received Placebo daily for a month. Patients received DCS capsules or placebo 1 h before sessions of CBT. Age, sex, kind of anxiety disorders “screen for child anxiety related disorders (SCARED)” and “cognitive abilities test (CATS)” scores were evaluated and compared between groups. Results: The mean age of the studied patients (29 females (80.6%) and 7 males (19.4%)) was 14.1 ± 1.8 years. The most frequent anxiety disorder among the study population was generalized social disorder (GAD) (77.7%). Age, sex and the frequency of anxiety disorders were not statistically significant between the study groups (P > 0.05). The mean score of “SCARED” and “CATS” at before starting the treatment, after treatment and three month after the treatment were not statistically significant between groups (P > 0.05). Also, decrease in values of “SCARED” and “CATS” during the evaluation time periods was not statistically significant between groups (P > 0.05). Conclusions: Findings of this study showed that there has been no difference in symptoms improvement in adolescent with anxiety disorder who received treatment protocol including 4 sessions of CBT, weekly, together with 50 mgs of DCS compared to the patients of the control group.

Background: Keratoconus is a progressive degenerative disorder of the cornea in which structural changes in the cornea cause it to become thin and conical in shape. Recently, collagen cross-linking (CXL) has been introduced as an effective intervention in management of progressive keratoconus. Accelerated CXL is a new protocol of this procedure which reduces corneal ultraviolet irradiation exposure time to 5 min. This study aimed to compare visual acuity, keratometry and topographic criteria of keratoconic eyes after conventional and accelerated CXL with a six-month follow-up. Materials and Methods: In this prospective interventional study we assessed eyes of 40 patients. Patients were divided into two groups randomly. One group underwent accelerated (5 min) CXL and the other underwent conventional (30 min) CXL. Visual acuity, topographic criteria and keratometry were assessed preoperatively and 6 months postoperatively. Results: In the present study we assessed 40 patients, 50% of which were right eye (OD) and 50% were left eye (OS). Mean age of patients in the accelerated group was 22.10 and in the conventional group was 22.80 years. Our results showed no significant differences between visual acuity, keratometric and topographic criteria in the two groups before intervention. Likewise our results manifested no significant difference between visual acuity, keratometric, refractive and topographic criteria after intervention. Conclusion: According to our survey topographic criteria and keratometry improvement in the accelerated and conventional protocol are the same. So accelerated protocol is suggested as a safe and effective option for management of progressive keratoconus.

Background: Melasma, a common acquired disorder of hyperpigmentation, especially in women, is often resistant to therapy. This study was aimed to evaluate the efficacy and safety of azelaic acid, resorcinol and phytic acid solution in chemical peeling of melasma in comparison to 50% glycolic acid. Materials and Methods: This clinical trial was performed, on 42 female patients with bilateral melasma. Severity of melasma was assessed by melasma area and severity index (MASI). Combination of (20% azelaic acid + 10% resorcinol + 6% phytic acid) was used as a new peeling agent on the right side of the face and 50% glycolic acid on the left side every 2 weeks for 6 times. Follow-up was carried out for 3 months after the last session. Any decrease in MASI score and unwanted complications following peeling were evaluated and compared during the trial. Results: Patients showed marked improvement as calculated with MASI score before and after treatment in both sides of the face. The efficacy of combination formula (azelaic acid, resorcinol and phytic acid) was similar to glycolic acid, but with fewer complications. There was no statistically difference in improvement between two groups (P > 0.05). However, the patient's discomfort following procedures was significantly lower with azelaic acid, resorcinol and phytic compared with the glycolic acid peels (P < 0.05) and there was the same duration in the beginning of the therapeutic response in both groups. Conclusion: Results showed that triple-combination was found to be an effective and safe peeling agent in the treatment of melasma and it was as effective as 50% glycolic acid peel.

Background: Mastitis is an inflammatory disorder in breast tissues due to bacterial factors, mycobacterial infections or autoimmune diseases. Idiopathic granulomatous mastitis (IGM) is a form of mastitis which may be affected by systematic diseases such as sarcoidosis, and infectious causes such as mycobacterium and fungus. This study evaluates the efficacy of medical therapy with a combination of corticosteroid and Azithromycin in patients with IGM. Materials and Methods: This study is a clinical trial research carried out in Alzahra Hospital (Isfahan, Iran) in 2013 on granulomatous mastitis patients. It was administered 250 mg of Azithromycin per 12 hour and 60 mg of Prednisolone per day within 2 weeks. Next, they took 40 mg/day within 8 weeks, and this dosage was tapered during 6 months and the patients clinically and radiologically followed up. The studied patients were examined within 1 week, 2 weeks, 1 month, 3 months, and 6 months, from the beginning of treatment. Results: This study investigated granulomatous mastitis patients in Alzahra hospital in 2013. The mean age of these patients was 33.6 ± 8.9, and their age range was 18–56 years old. Among 26 studied patients, 24 persons (92.3%) according to follow-up the patients by physical examination and sonography responded to treatment of corticosteroid and Azithromycin. The remaining (7.7%) underwent surgery. Treatment periods in case of drug use were respectively, 8.5 ± 0.71 months. Conclusion: Treatment with corticosteroid and Azithromycin is an effective and appropriate treatment for IGM.

Background: To evaluate the correlation of magnetic resonance imaging (MRI) features of breast lesions of Breast Imaging Reporting and Database System (BI-RADS) category 4 with histopathologic results. Materials and Methods: In a prospective study between December 2013 and April 2015, patients with suspicious mammographic and/or ultrasound findings referred for Breast MRI were evaluated. Patients with lesions of BI-RADS category 4 were enrolled with a written informed consent. In each patient, mass lesion (ML) or nonmass lesion (NML) was determined, and different characteristics of the lesions were recorded. A follow-up program was taken with mean 3–12 months. Patients who underwent core needle biopsy or open biopsy were summoned. Results: Seventy-eight females aged 24–67 years (mean 43.1 ± 8.8) met the inclusion criteria and had adequate samples for histopathologic study. Twenty-nine (37.2%) patients had ML and 49 (62.8%) patients had NML. Tissue sampling in 63 (80.7%) patients was through core needle biopsy and in 15 (19.2%) patients through surgery. A wide spectrum of benign and malignant pathologic diagnoses was seen. In statistical analysis, none of the MRI features has a significant correlation with any specific histopathologic diagnosis (P = 0.185). However, the relation between the MRI category (ML or NML) and pathology results was significant at level of 0.1 (P = 0.06). Conclusion: This study showed that a wide spectrum of histopathologic results is seen in BI-RADS category 4. However, in this sample volume, none of the MRI features in this BI-RADS category has a significant correlation with any specific histopathologic diagnosis.

Background: Colorectal cancer (CRC) is one of the most commonly diagnosed cancers worldwide. It is also known as the second leading cause of deaths as the early stage detection is not yet available by current methods. So identification of biomarkers can also be functional in early diagnosis and prognosis. Materials and Methods: We examined sera from 60 CRC patients of different stages as a source of auto-antibody as well as two human CRC cell lines with different invasive capacities (SW48 and SW1116) as the source of antigens. The pattern of immune reactivity in immuneblotting tests between mentioned cell lines and CRC patients' sera were evaluated by ImageJ software. Results: The Immune reactivity pattern of two cell lines (SW48 and SW1116) with CRC patients' sera were different in band intensities and the most immune reactivity intensity was observed in SW48 cell lysate with sera from Stage III CRC patients. Conclusion: Due to the humoral immune response, sera from Stage III CRC patients contained autoantibodies that demonstrated higher immune reactivity. Moreover, SW48 cell line with high aggressive behavior reacted to CRC patients' sera with greater intensity compared with less aggressive behavior cell line (SW1116). Therefore, it is required to use other techniques such as two-dimensional electrophoresis and mass spectrometry.

Bachground: Peritonitis and exit site (ES) infection are two main complications of peritoneal dialysis. There are some controversies regard to preventive strategies for ES care. In this study we compared peritonitis and ES infection rates in patients with and without dressing. Materials and Methods: This historical cohort study carried out on 72 patients under continuous ambulatory peritoneal dialysis treatment, 54 with dressing versus 18 patients without dressing, followed from October 1, 2010 to March 31, 2011 for peritonitis and ES infection. Results: A total of 17 episodes of ES infection occurred in 12 patients in dressing group, but no case was seen in no-dressing group (P = 0.02). Twenty-one episodes of peritonitis occurred in 15 patients in both groups (one episode every 20.6 patient-months). In no-dressing group two episodes occurred in only one patient (one episode every 54 patient-months), and in dressing group, 19 episode in 14 patients (one episode every 17.1 patient-months) (P = 0.03). Peritonitis was significantly more frequent in male versus female in overall patients (38% vs. 14%, P = 0.025) and in dressing group (52% vs. 15%, P = 0.003). In dressing group, peritonitis was more frequent in diabetics versus non-diabetics (48% vs. 11%, P = 0.01). Odds ratio for developing peritonitis was 9.4 in dressing group (95% confidence interval [CI] =1.05 − 84.4; P = 0.045), and 4.4 in men (95% CI = 1.26 − 15.19; P = 0.02). Conclusion: In this study, chronic ES care without dressing was associated with lower risk of peritonitis and ES infection.

Background: This study aimed to compare the effects of the schema along with mindfulness-based therapies in the psoriasis patients. Materials and Methods: This semi-experimental study with post- and pre-tests was conducted on the psoriasis patients in the Dermatology Clinic of the Isfahan Alzahra Hospital, Iran using the convenience sampling in 2014. The patients had a low general health score. The experimental groups included two treatment groups of schema-based (n = 8) and mindfulness (n = 8). Both groups received eight 90-min sessions therapy once a week; they were compared with 8 patients in the control group. To evaluate the psoriasis patients' maladaptive schema, Young schema questionnaire was used. Data were analyzed through the covariance analysis test. Results: There was a significant difference between the schema-based therapy and mindfulness groups with the control group. There was also a significant difference between the schema-based therapy groups consisting of the defeated schema, dependence/incompetence schema, devotion schema, stubbornly criteria schema, merit schema, restraint/inadequate self-discipline schema, and the control group. Moreover, a significant difference existed between the maladaptive schema of mindfulness therapy group and the controls. There was a significant difference concerning the improvement of the psychopathologic symptoms between the mindfulness therapy group and the control group. Conclusions: This study showed similar effects of both the schema and mindfulness-based therapies on the maladaptive schemas in improving the psoriasis patients with the psychopathologic symptoms.

Background: Several common factors have been identified for smoking and depression. The The present study explores the relation of psychological and familial factors with depression, by student smoking behavior. Materials and Methods: A total of 5500 middle- and high-school students were selected in Isfahan province in 2010. A self-administered questionnaire collected data on background characteristics, smoking status, depression, and risk factors. Univariate analysis multiple logistic regressions were conducted to compare between depressed and nondepressed people by adolescent smoking status. Odds ratios and the corresponding 95% confidence intervals (CIs) were reported. Results: Fathers lower education attainment was accompanied adolescents higher depression prevalence. Parental smoking and sibling smoking increased the depression likelihood by 1.41 (95% CI: 1.18, 1.68) and 1.43 folds (95% CI: 1.04–1.94) for never-smokers. Positive attitude toward smoking increased the probability of depression by 1.18 among never-smokers. Never-smokers lacking refusal skill had 1.23 (1.03–1.47) higher chance of depression. A higher level of self-efficacy related to lower chance of depression. Taking risky behavior, increased the depression likelihood by 1.56 (95% CI: 1.29–1.89) in never-smokers, by 1.85 (95% CI: 1.37–2.44) in experimental smokers, and by 1.14 times (95% CI: 1.01–1.72) in current smokers. Family conflict increased depression chance by 2.25 times (95% CI: 1.89–2.66) in never-smokers, by 1.95 (95% CI: 1.46–2.61) in experimental smokers, and by 2.06 times (95% CI: 1.38–3.08) in current smokers. Conclusions: Targeting self-efficacy level, risky behavior, and family conflict can drop the comorbidity of smoking and depression simultaneously. This may help public health practitioners and policymakers to develop common strategies in reducing adolescents smoking and depression comorbidity.

Background: Wound healing is a complex process leading to regeneration of damaged skin tissue. Arnebia euchroma (AE) have many effective activities such as anti-inflammatory, antimicrobial, antioxidative, and anti-tumoral effects. The extract of AE has positive effects on burn wounds. This study is designed to investigate the healing effects of AE on excisional wounds in rats. Materials and Methods: Thirty six rats with the age of 8 weeks divided into three groups. One group (E1) was treated with AE gel at a concentration of 10%. Control group (C1) received normal saline and the vehicle group (C2) was treated with carboxymethyl cellulose gel as the vehicle for 14 days. Stereological analysis was done to investigate the collagen bundle and hair follicale synthesis, vascularization, fibroblast proliferation. Pathological evaluation was also conducted. Results: In this study, pathological evaluation showed severe acute inflammation in C2 group, chronic and acute inflammation in C1 and also more wound contraction in E1 in comparison with other groups. There was a meaningful difference between E1 and C1 regarding fibroblast proliferation (P < 0.05). Conclusion: Results of this study revealed the healing effect of AE on excisional wounds and recommend its administration after further clinical investigations.
