Background: Posterior urethral injury usually occurs in male patients with pelvic fractures. Posterior urethral injuries are associated with considerable morbidity including urinary incontinence, erectile dysfunction and urethral stricture. Objective: To compare the outcomes between early primary endoscopic realignment and delayed reconstruction in the management of male patients of posterior urethral injury. Methodology: This prospective study was conducted in the department of urology and department of casualty, Dhaka Medical College Hospital, Dhaka, Bangladesh from July 2015 to June 2017 among 50 male patients with posterior urethral injury. Fifty patients were randomly allocated into two groups;the group A consisted of 24 patients underwent early primary endoscopic realignment within 10 days after posterior urethral injury and the group B consisted of 26 patients underwent delayed reconstruction in form of anastomotic urethroplasty after 3 months. All patients were followed up at 3rd, 6th and 9th month after the procedure. Outcome variables were post-operative urethral stricture, urinary incontinence and erectile dysfunction. Data were analyzed and compared by statistical tests. Results: The mean (±SD) age of the study patients was almost similar between the groups (28.8 ± 8.4 vs. 27.4 ± 7.2 years, p = 0.486). In group A, 83.33% patients developed postoperative urethral stricture, none of them developed urinary incontinence and 20.83% developed erectile dysfunction;On the other hand, in group B, these rates were 38.46%, 23.07% and 38.46% respectively. Postoperative urethral stricture formation was significantly higher in Group A (p = 0.0012) but urinary incontinence and erectile dysfunction rates were significantly higher in Group B (p = 0.018 and p = 0.042 respectively). Conclusion: Early primary endoscopic realignment is better than delayed reconstruction in the management of male patients with posterior urethral injury. It provides less postoperative complica

Background: Impaired fasting glucose (IFG) is a prediabetic condition and is a high-risk state for developing diabetes and associated complications. The aim of this study was to explore the association of vitamin D with insulin secretory function among the IFG subjects. Materials and Methods: This was a prospective cross-sectional study conducted in the Department of Biochemistry and Cell Biology, Bangladesh University of Health Sciences (BUHS), Dhaka, Bangladesh;from June 2016 to May 2017, on forty-six (46) IFG subjects. Serum blood glucose was measured by glucose-oxidase method, Fasting serum lipid profile (Total cholesterol, TG and HDL-c);liver enzyme like alanine aminotransferase (ALT) was measured by enzymatic-colorimetric method;Serum creatinine was measured by colorimetric kinetic method;Serum Insulin and vitamin D [25(OH)D] were measured by ELISA method;insulin secretory capacity (HOMA%B) and insulin sensitivity (HOMA%S) were calculated by Homeostasis Model Assessment (HOMA) using HOMA-CIGMA software. Results: Among 46 IFG subjects, 22 (47.8%) were male and rest 24 (52.2%) were female and their mean age was 40 (±8) years. Mean fasting serum glucose level of the study subjects was 6.33 (±0.23) mmol/l and mean postprandial serum glucose level was 7.23 (±0.41) mmol/l. Mean serum vitamin D level of the study subjects was 26.54 (±8.83) ng/ml. Mean HOMA%S, HOMA%B and HOMA%IR of the total study subjects were 48.34 (±16.70), 102.16 (±23.13) and 2.28 (±0.70) respectively. Insulin secretory capacity (HOMA%B) was significantly higher (p = 0.047) in the subjects having higher vitamin D [25(OH)D level ≥ 20 ng/ml] compared to the subjects having lower vitamin D [25(OH)D levels Conclusion: High prevalence of hypovitaminosis D exists among IFG subjects.

Ghulsan Dhaka Bangladesh Zilla-Sadar Hospital Hobigong Bangladesh Department of Nephrology Bangabandhu Sheikh Mujib Medical University (BSMMU) Dhaka Bangladesh

Background: Transurethral resection of prostate (TURP) is the gold standard in the surgical treatment of symptomatic benign prostatic hyperplasia (BPH). Blood loss is one of the most common complications of TURP. Objective: To evaluate the effect of preoperative dutasteride on bleeding related to TURP in patients with BPH. Materials and Methods: This prospective interventional study was done in the department of urology, Dhaka Medical College Hospital, Dhaka, Bangladesh during the period of July 2016 to June 2017. A total of 70 cases of BPH planned for TURP were included in this study according to the statistical calculation. Patients were randomly allocated to control group A (TURP without dutasteride) and dutasteride group B (TURP with dutasteride). Each group consisted of 35 patients. Group B patients were treated with dutasteride 0.5 mg/day for 4 weeks before TURP. The main outcome of blood loss was evaluated in terms of reduction in serum hemoglobin (Hb) and hematocrit (Hct) levels, which were measured before and 24 hours after surgery. Data were analyzed and compared by statistical tests. Results: Comparison of outcome between groups shows that there was a significant difference in term of pre-post operative change of hemoglobin and hematocrit levels in the control group A compared to the dutasteride group B (Hb = 2.96 ± 0.80 gm/dl vs. 1.81 ± 0.71 gm/dl, respectively, p = 0.001;Hct = 11.20% ± 2.12% vs. 6.07% ± 2.02%, respectively, p = 0.02). A significant lower mean blood loss was observed in the dutasteride group compared to the control group. Conclusion: Preoperative dutasteride therapy reduces blood loss related to TURP in patients with BPH. This therapy can be practiced to reduce surgical bleeding associated with TURP.

A Galvanostatic Modeling for Preparation of Electrodeposited Nanocrystalline Coatings by Control of Current Density

引用

Journal of Materials Science & Technology 2012年第12期28卷 1071-1076页

作者： ali mohammad Rashidi School of Engineering Razi UniversityP.O. Box 67149-67346 Kermanshah Iran

The correlation between the grain size of electrodeposited coatings and the current densities was modeled by considering galvanostatic conditions. In order to test the model by experimental results, nanocrystalline （NC） nickel samples were deposited at different current densities using a Watts bath. The grain size of the deposits was evaluated by X-ray diffraction （XRD） technique. Model predictions were validated by finding a curve being the best-fit to the experimental results which were gathered from literature for different NC coatings in addition to those data measured in this research for NC nickel coatings. According to our model, the variation of grain size with the reciprocal of the current density follows a power law. A good agreement between the experimental results and model predictions was observed which indicated that the derived analytical model is applicable for producting the nanocrystalline electrodeposits with the desired grain size by controling current density.

Journal of Central South University 2015年第8期22卷 3141-3150页

作者： Mohsen-ali Shayanfar mohammad-ali Barkhordari mohammad Ghanooni-Bagha The Centre of Excellence for Fundamental Studies in Structural Engineering Iran University of Science and TechnologyP.O.BOX: 16765-163 Narmak Tehran Iran

Reinforcement inside the concrete is protected from corrosion and its damages until several years after the construction. After corrosion initiation, the cross section of reinforcement begins to reduce and often load bearing of the reinforced concrete structure will be reduced significantly. Corrosion of reinforcements in concrete in polluted and contaminated areas can occur in two ways: chloride and carbonation. In this work, meta-heuristic approach of charged system search(CSS) is used to calculate corrosion occurrence probability due to chloride ions penetration. The model efficiency is verified by comparing the available examples in technical literature and results of Monte Carlo analysis. According to the analyses performed, using different probabilistic distributions regardless of probabilistic moments based on real distribution leads to diverse results. In addition, influence of each effective parameter in corrosion occurrence varies by changing other parameters.
