To determine the value of the gonadotrophin-releasing hormone (GnRH) test in selecting which infertile patients with varicocele would benefit from varicocelectomy.
The study comprised 30 patients ...with varicocele who presented between November 1993 and May 1994, and 10 control subjects. The basal serum level of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) were determined and all participants given 100 micrograms of GnRH nasally. The levels of FSH and LH were then determined for up to 2 h. The patients then underwent varicolectomy and the response was evaluated by comparing sperm quality before and after treatment and between those with increased or normal FSH and LH levels in response to the GnRH test.
Those patients who had increased FSH and LH levels after the GnRH test had a mean 121% increase in sperm density (P < 0.001), a 23% increase in sperm motility (P < 0.001) and a 40% decrease in sperm abnormality (P < 0.05). The respective values for those with normal levels of FSH and LH were 15% (P < 0.05), 11% (P > 0.05) and 11% (P > 0.05).
The GnRH test is useful for determining those patients who should benefit from varicocelectomy.
The objectives of this study were to compare the protective influence of exogenous nitric oxide on renal ischemia reperfusion (I/R) injury with that of the antioxidant vitamins C and E. ...Sprague-Dawley rats were divided into three groups ( n=12 per group). Normal saline solution was given in group 1, a vitamin C (200 mg/kg/d) plus vitamin E (100 mg/kg/d) combination in group 2 for 3 days before operating and Na-nitroprusside (5 mg/kg/d) in group 3 before reperfusion. The left kidneys were exposed to warm ischemia for 40 min followed by reperfusion for 90 min. The right kidneys were used as internal controls. After both kidneys were removed, histopathological examinations were performed, and oxidative and antioxidative parameters were measured. In the postischemic reperfused rat kidneys, the renal lipid peroxidation level was significantly lower, and the renal GSH level higher in the group given Na-nitroprusside compared with groups 1 and 2. Renal specific xanthine oxidase activity was also significantly lower in the group treated with Na-nitroprusside than in the groups given vitamins or saline. There was a significant, negative correlation between lipid peroxidation and reduced glutathione levels. Our results suggest that the exogenous nitric oxide (Na-nitroprusside) inhibits xanthine oxidase, and has more apparent preventive features for renal I/R injury than the antioxidant vitamins C+E.
Circumcision has always been regarded as both an important social event and a milestone of a young man's life in Turkish culture, especially in the Ottoman period. Herein we study an exceptional ...circumcision festivity which lasted 15 days in the early autumn of the year 1720, for the 4 princes of Sultan III Ahmed, some sons of two high-ranking Ottoman officials and thousands of male children of poor citizens of Istanbul as representing the beneficent of the Sultan. All the organizations of the Empire participated in this huge event, including many shows and a feast, and the preparations were initiated months before. Traditionally, this kind of important social event of Ottoman culture had been described in a literary manner, and Surname-i Vehbi was the special name for the book of this circumcision festivity with 137 colored paintings and a total of 175 pages. The original of this work, which is in the library of Topkapi Palace Museum in Istanbul, was written by Vehbi and illustrated by Levni. The importance of this antique book is that it is the last important example of the illustrated festivity books of Ottoman literature.

Retroperitoneal fibrosis was first described in 1905 by Albarran, a French urologist, who performed ureterolysis for ureteral compression produced by the disease. However, this disease became an ...established clinical entity by Ormond's account in the English literature in 1948. Pericystitis plastica has been used the define an extremely rare type of Idiopathic retroperitoneal fibrosis (IRF) constricting the bladder. In this study, we discussed the recovery of 29-year-old woman with pericystitis plastica who was misdiagnosed as pelvic malignancy or a chronic/subacut pelvic inflammation at the first evaluation.

To investigate whether ordinary tests used in urolithiasis can increase the diagnostic value of unenhanced helical computed tomography (HCT).
Of all patients admitted with acute flank pain, 137 ...without radiocontrast allergy, pregnancy and renal insufficiency were included in the study. After urinalysis (Ur) and ultrasonography (USG), HCT without a contrast agent was taken by 5-mm collimation, thereafter excretory urography (EU) was obtained. Confirmation of a stone was done by various tests and/or treatment methods. Statistically, the predictive values of HCT, USG, EU and Ur and their combinations were evaluated using the area under the receiver operating characteristic curve (AROC).
The patients' mean age was 38 (range 4-72) years. Sensitivity values of HCT, USG, EU and Ur were 97, 69, 71 and 81%, respectively. Their specificity values were 96, 87, 91 and 65%, respectively. The widest AROC was found for HCT (97%). The best test combination was HCT or USG according to the AROC value (93%), but none of the AROC values of the test combinations was higher than that of HCT. However, 95% confidence intervals of the AROC values of these tests and their combinations overlapped.
Because the HCT combinations with other tests improved the diagnostic value of HCT, they should be preferred in some individuals suspected of having urolithiasis. However, the most feasible single test meeting the all usage purposes was HCT in terms of the AROC value, and the combination was HCT or USG in which either HCT or USG was positive.
This research and development aims to produce Android-based mathematics learning media using the Realistic Mathematics Education (RME) approach is valid and practical criteria. This development uses ...the ADDIE development model which consists of analyze, design, development, implementation, and evaluation. But due to time constraints and the Covid-19 pandemic, this research does not use the stage. implementation and only arrived at the development stage. The results of the analysis at the validation test stage by the validator produced a percentage based on 2 aspects, namely 80.67% material and 86% media aspects included, and The average percentage of learning media validity is 83.33% so that the learning media is included in the very valid category. Furthermore, the results of the analysis of the practicality test 10 phase by class X produced an average percentage of 86,66% and entered the very practical criteria. Based on the validity test and practicality test carried out, it can be concluded that the Android-based mathematics learning media uses the Realistic Mathematics Education (RME) approach declared valid and practical to use.
