Background: The aim was to assess the effect of vasopressin in reducing the time of surgery, amount of bleeding, and fluid deficit during hysteroscopic myomectomy of submucosal myoma from 2016 to 2018. Materials and methods: This study was conducted as a prospective, randomized, single-blinded clinical trial on the premenopausal women ranged from 18 to 62 years' old. A number of 80 patients were randomly assigned to each arm of the study according to random consecutive numbers. The control group (n = 40) of patients underwent conventional hysteroscopic myomectomy without vasopressin and the case group (n = 40) underwent hysteroscopic myomectomy with the injection of diluted vasopressin. Measured outcomes were time for myomectomy, fluid deficit, inflow volume, visual clarity, and postoperation hemoglobin level. Results: The mean time of myomectomy was 38.1 and 77.38 min in vasopressin and control groups, respectively (P < 0.001). The mean inflow volume was 2800 and 4100 in vasopressin and control groups, respectively (P = 0.029). The visual clarity score was 8.5 and 6.5 in the vasopressin and control groups, respectively (P < 0.001). Conclusions: The injection of vasopressin during hysteroscopic myomectomy is effective in the management of fluid deficit, time of surgery, and improvement of visual clarity.

Background: The surface of endothelial cells is covered with cell adhesion molecules including E-selectin, intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule 1 (VCAM-1) that mediate the adhesion and extravasation of leukocytes and play a pivotal role in inflammatory response. The aim of this study was to investigate the role of expression of adhesion molecules in inflammatory bowel disease (IBD) patients, irritable bowel syndrome (IBS) patients, and normal colonic mucosa. Materials and Methods: IBS and IBD patients along with normal colonic mucosa were recruited in the study. In all groups, two biopsies were taken from each of the three anatomical sites (terminal ileum, cecum, and rectum). Three monoclonal antibodies, E-selectin mAb, VCAM-1 mAb, and ICAM-1 mAb, were applied for immunohistochemical analysis. Results: In IBD patients, the expression of intensity of E-selectin, VCAM-1, and ICAM-1 was found decreased, at least in cecum and rectum, in comparison with IBS patients and controls (P < 0.001, P < 0.005, and P < 0.007, respectively). Comparison of the expression of intensity of the aforementioned molecules in IBS patients and controls revealed significant augmentation at the cecum and rectum of IBS patients. Conclusions: The expression of adhesion molecules appeared lower in IBD patients compared to IBS patients and controls. In addition, the expression of adhesion molecules appeared higher in IBS compared to the control group. Therefore, it could be hypothesized that the expression of adhesion molecules could be considered as an early event in the process of proinflammatory IBS group and may be other factors play a crucial role in the process of intestinal inflammation in IBD patients.
