Anxiety, depression and stressful life events among medical students : a prospective study in Antalya, Turkey

To assess psychological changes in medical students in Antalya, Turkey during their undergraduate education. The first‐year follow‐up outcomes are presented in this article.

Comparing two ureter reimplantation techniques in kidney transplant recipients

We compared the incidence of urological and anastomotic complications for the ureteroureterostomy and Lich–Gregoir techniques in kidney transplant recipients. Between May 2003 and February 2004, 75 kidney transplant recipients from living donors were divided into two similar groups to receive ureteroureterostomy (n = 41, 28 male, 13 female) and Lich–Gregoir techniques (n = 34, 24 male, 10 female) for ureteral reimplantation. Patients with vesicoureteral reflux (VUR) to the native kidneys were excluded from the study. The urological complications included complicated hematuria, ureteral stenosis, symptomatic VUR, recurrent urinary tract infection (UTI). There was no statistical significance between two groups in terms of gender, age, end‐stage renal disease etiology, human leucocyte antigen (HLA) mismatch numbers, type and duration of dialysis, and cold ischemia time. The incidence of urologic and anastomotic complications was 12%. Complications in the Lich–Gregoir group included symptomatic VUR in 8.8% and stent migration in 2.9% of cases. Complications observed in the ureteroureterostomy group were ureteral stricture 7.3% and complicated hematuria in 4.9% of cases. However, symptomatic reflux was not observed in the ureteroureterostomy group. UTI frequency was similar in both groups. Ureteroureterostomy can be safely performed as a primary choice in kidney transplant recipients.

Germline mutations of BRCA1 and BRCA2 genes in Turkish breast, ovarian, and prostate cancer patients

Distribution and prevalence of germline mutations in BRCA1 and BRCA2 differ among different populations. For the Turkish population, several studies have addressed high-risk breast cancer and ovarian cancer (BC-OC) patients. In most studies, both genes were analyzed in part, and a quite heterogeneous mutation spectrum was observed. For high-risk Turkish prostate cancer (PCa) patients, however, there are no data available about mutations of germline BRCA genes. To accurately determine the contribution of germline mutations in BRCA1 and BRCA2 in Turkish BC, OC, and PCa high-risk patients, 106 high-risk BC-OC patients, 50 high-risk PCa patients, and 50 control subjects were recruited. The study represents the only full screening, to date, of a large series of Turkish high-risk BC-OC patients and the only study in Turkish high-risk PCa patients. Mutation screenings were performed on coding exons of both genes with either denaturing gradient gel electrophoresis or denaturing high performance liquid chromatography, or with both techniques. Three deleterious mutations in BRCA1 and three deleterious mutations in BRCA2 were detected in different BC-OC patients, and one truncating mutation was detected in a high-risk PCa patient. In addition, 28 different unclassified and mostly novel variants were detected in both genes, as well as several silent polymorphisms. These findings reflect the genetic heterogeneity of the Turkish population and are relevant to genetic counseling and clinical management.
