Age distribution types of bladder cancers and their relationship with opium consumption and smoking.

BACKGROUND: Recognition of the predisposing factors of bladder cancer is very important and provides possible prevention measures. The aim of this study was to investigate the types, distribution of bladder tumors and their relationship with opium consumption and smoking in patients who referred to Shahid Beheshti Hospital, Babol, Iran. METHODS: In this case-control study, all patients diagnosed with bladder cancer who underwent surgery during 2001-2012 were enrolled. The subjects of the control group were selected among the patients who underwent ERCP (endoscopic retrograde cholangiopancreatography) for gallstone and had no tumors and genitourinary problems. Data regarding demographic, pathology reports and tumor type, smoking status, history of opium consumption and its duration were collected. Patients and controls were compared using t-test and chi-square test. SPSS software Version 20 was used for analysis. RESULTS: In this study, 175 patients with an average age of 63.30±15.29 years and 175 age- matched controls were studied. A significant association was observed between smoking and opium consumption with bladder cancer (P=0.001 for both). CONCLUSION: The results of this study showed that opium consumption and smoking are associated with bladder cancer.

Unresolved abdominal mass in an adult cryptorchid testis: a case report.

This case study aims to report an unresolved abdominal mass in an adult with cryptorchid testis and provide a review of related literature. We investigated a 54-year-old man who had cryptorchidism with a history of left orchiectomy 18 years prior. He was diagnosed with an intra-abdominal testicular mass after referring to the emergency ward with pelvic pain. The incidence of testicular cancer in undescended testicles is 40 times greater in the general population. In developed countries, the existence of undescended testicles in adult population is rare, which could be due to systematic practice of elective orchidopexy before the second year of life as well as orchiectomy in post-adolescent patients with undescended testicles. Despite these preventive measures, there are still some isolated cases of intra-abdominal testicular tumors in adults.
