Multiple primary malignancies (MPMs) are two or more primary malignancies diagnosed in the same patient at the same time or at a specific time and do not represent progression, recurrence or metastasis of the first tumor.MPMs are extremely rare. In this paper, we reported a case of male patient who was diagnosed with invasive uroepithelial carcinoma, rectal adenocarcinoma, clear cell renal cell carcinoma and sarcomatoid carcinoma of the bladder, and open partial cystectomy, laparoscopic radical operation for rectal cancer, laparoscopic partial left nephrectomy, transurethral resection of bladder tumor and laparoscopic radical cystectomy with ureterostomy were performed, respectively.The patient was followed up for 16 months after the last surgery, with good general condition and no recurrence or metastasis.

Clinical applications of rigid dilatation using double catheters method for ureteric stenosis / 中国医师进修杂志

Objective To evaluate the clinical applications of rigid dilatation using double catheter method for ureteric stenosis.Methods The clinical data of 51 ureteric stenosis patients who had underwent rigid dilatation using double catheters method were retrospectively analyzed. Results Among the 51 patients,the ureteroscopy successfully went through the stricture in 46 cases(90.2%),and all patients had no ureteral perforation or laceration.Among the 5 patients in whom ureteroscopy did not go successfully through the stricture,2 cases were placed double J tube,2 cases underwent percutaneous nephrolithotomy,and 1 case underwent two stage ureteral stricture resection and religation.All patients were examined by ultrasound examination 3 months after the treatment,and the degree of hydronephrosis was partial remission. Conclusions The double catheters method is a safe and effective way for rigid dilatation for ureteric stenosis,and it is worth popularizing.

Preliminary Study on the Mode of Inheritance of Male Pattern Alopecia (MPA) / 昆明医科大学学报

95 probands' family frees of MPA have been studied by the methods of simple segregation analysis and estimation of heritability. The result shows that MPA may be caused by different hereditary patterns. In the families with affected parents and vertical transmission. MPA may be caused by an autosomal dominant (AD) gene, making up 56.84% (AD) and 2.11% (reduced penetrance). It also shows that MPA may be due to polygenic inheritance.
