DOI
:10.4103/2277-9175.217217
PMID
:29279832
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.

Nahid Ramezani Jolfaie, Mohammad Hossein Rouhani, Maryam Mirlohi, Mina Babashahi, Saeid Abbasi, Peiman Adibi, Ahmad Esmaillzadeh, Leila Azadbakht
Adv Biomed Res
2017, 6:131 (16 October 2017)
DOI
:10.4103/2277-9175.216784
PMID
:29142894
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.

2017, 6:129 (16 October 2017)
DOI
:10.4103/2277-9175.216782
PMID
:29142892
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.

2017, 6:128 (16 October 2017)
DOI
:10.4103/abr.abr_554_13
PMID
:29142891
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.

DOI
:10.4103/2277-9175.216781
PMID
:29142890
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.

PMID
:29142888
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.

Hassan Razmjoo, Mohammad Ghoreishi, Azadeh Mohammadi Milasi, Alireza Peyman, Zahra Jafarzadeh, Mohadeseh Mohammadinia, Nasrollahi Kobra
Adv Biomed Res
2017, 6:123 (16 October 2017)
DOI
:10.4103/2277-9175.216777
PMID
:29142886
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.
