[EX Q]: THE AIM OF THE STUDY WAS: Is primary Arterio-venous fistula the vascular access of choice for adequate dialysis and better patient outcome in end stage renal disease.', 'The present study was done in the department of cardiovascular and thoracic surgery at Sher-i-Kashmir institute of medical sciences, Soura, Srinagar Kashmir. Native Arterio-Venous (AV) fistulas were made in the patients with end stage renal disease for performing hemodialysis. They were followed for patency and adequacy of blood flow during hemodialysis. All the patients were operated under local anesthesia.', 'The results showed that 77% of the AV fistulas based on radial artery with side-to-side anastomosis and 80% of those with end-to-side anastomosis were functionally patent after one year. After two years, the patency rate in side-to-side and end-to-side anastomosis was 50% and 55%, respectively. In addition, the patency rate was 90% in brachial artery based AV fistula with end-to-side anastomosis, whether done primarily or secondarily, at the end of one year. However, a rapid decline was observed in the patency rate during the third year in both radial artery based and brachial artery based AV fistulas.

[EX Q]: We aimed to investigate structural abnormalities in first-episode remitted geriatric depression (RGD) with optimized voxel-based morphometry (VBM) in closely matched patients and healthy control subjects and examine the relationship of performances on neuropsychological tests with regional gray matter volumes.', 'Nineteen subjects with first-episode RGD and 16 well-matched healthy control subjects were recruited for this study, and neuropsychological tests and magnetic resonance imaging were conducted on the subjects. The differences in regional gray matter volume were determined between these two groups by optimized VBM.', 'The volumes of right superior frontal cortex, left postcentral cortex, and right middle temporal gyrus were significantly smaller in patients with RGD relative to healthy control subjects. However, patients with RGD had larger left cingulate gyrus volume compared with healthy control subjects. There was a significant negative correlation between left cingulate gyrus volume and Rey Auditory Verbal Learning Test delayed recall raw score in patients with RGD.

[EX Q]: Pathophysiological mechanisms leading to chordee in patients with hypospadias and to the hidden state of buried penis in the prepubic fat remain unclear. Resection of dartos tissue usually makes the penis straight in patients with hypospadias and corrects it in those with buried penis, suggesting a common pathophysiology related to dartos tissue.', 'Tissue samples from 113 children undergoing primary penile surgery for hypospadias (94 patients), epispadias (1) or buried penis (18) were collected between November 2011 and September 2013. Tissue samples from 79 children undergoing circumcision for nonmedical reasons served as controls. All samples were stained with smooth muscle actin and analyzed by the same pathologist, who was blinded to indication for surgery. Chi-square and Fisher exact tests were applied.', 'Three different dartos tissue patterns were observed. Pattern I (normal) consisted of smooth muscle fibers of dartos tissue organized in a parallel configuration in the subcutaneous tissue. Pattern II was characterized by poorly developed and hypotrophic smooth muscle fibers. Pattern III was determined by randomly distributed smooth muscle fibers in the subcutaneous tissue, without parallel configuration. Pattern I was observed in 45 circumcision specimens (64%). Of buried penis cases 78% were considered abnormal (pattern II in 4 cases and III in 10, p = 0.001). Of hypospadias cases 70% were considered abnormal (pattern II in 31 cases, III in 32, and mixed II and III in 3, p < 0.001). The only epispadias case was designated pattern II.
