Purpose: To investigate the effects of all-trans retinoic acid (ATRA) in cisplatin (CP)-induced testicular damage in rats. Materials and Methods: Twenty-eight male Wistar rats were divided into four groups: Control, ATRA alone, ATRA+CP, and CP alone. Body weight, testicular weight, sperm count, sperm motility, percentage of abnormal sperm, total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI) in testicular tissue, and testicular histopathology were compared among groups. Results: The sperm count and motility significantly decreased and the percentage of abnormal sperm significantly increased in the CP group compared to the control and ATRA groups. CP+ATRA administration significantly increased the sperm count and motility, but reduced the abnormal sperm count. CP administration significantly increased TOS and OSI compared to the control group and the other groups. Administering CP+ATRA significantly decreased TOS and the OSI in testicular tissue and reduced spermatogenesis, but increased the Johnsen score. Conclusions: The destructive effects of CP treatment on testicular tissue and spermatogenesis were reduced by administering ATRA.

Background: To evaluate the incidence, diagnosis and management of GTN among 28 centers in Turkey. Materials and Methods: A retrospective study was designed to include GTN patients attending 28 centers in the 10-year period between January 2003 and May 2013. Demographical characteristics of the patients, histopathological diagnosis, the International Federation of Gynecology and Obstetrics (FIGO) anatomical and prognostic scores, use of single-agent and multi-agent chemotherapy, surgical interventions and prognosis were evaluated. Results: From 2003-2013, there were 1,173,235 deliveries and 456 GTN cases at the 28 centers. The incidence was calculated to be 0.38 per 1,000 deliveries. According to the evaluated data of 364 patients, the median age at diagnosis was 31 years (range, 15-59 years). A histopathological diagnosis was present for 45.1% of the patients, and invasive mole, choriocarcinoma and PSTTs were diagnosed in 22.3% (n=81), 18.1% (n=66) and 4.7% (n=17) of the patients, respectively. Regarding final prognosis, 352 (96.7%) of the patients had remission, and 7 (1.9%) had persistence, whereas the disease was mortal for 5 (1.4%) of the patients. Conclusions: Because of the differences between countries, it is important to provide national registration systems and special clinics for the accurate diagnosis and treatment of GTN.
