RESUMEN
The CpG promoter methylation has been reported to occur frequently in bladder cancer. Moreover, analysis of gene methylation has been shown to be feasible from voided urine and can be detected with a high degree of sensitivity. The aim of this present study is to determine how methylation patterns of APC, RARβ and Survivin genes change during bladder carcinogenesis and to evaluate whether DNA methylation could be detected in urine sediment. Using the sensitive assay of MSP, we explored the promoter methylation status for the three genes in tumor specimens and urine sediment DNA from 32 bladder cancer patients. Methylation frequencies of the tested genes in tumor specimens were 100%, 75% and 84.4% for APC, RARβ and Survivin, respectively. Hypermethylation of APC was found in all pathological grades and stages of bladder cancer. More frequent promoter hypermethylation of RARβ and Survivin was observed in high grade tumors and the hypermethylation increased from low to high stages, but there was no significant correlation between stages/grades and hypermethylation of these two gene promoters. In order to investigate clinical usefulness for noninvasive bladder cancer detection, we further analyzed the methylation status in urine samples of bladder cancer patients. Methylation of the tested genes in urine sediment DNA was detected in the majority of cases that were hypermethylated in tumor samples (93.7%) and the frequencies were 79.3% 70.8% and 96.3% for APC, RARβ and Survivin, respectively. Our results indicate that methylation of APC, RARβ and Survivin gene promoters is a common finding in patients with bladder carcinoma. The ability to detect methylation not only in bladder tissue, but also in urine sediments, suggests that methylation markers are promising tools for noninvasive detection of bladder cancer.

Prostatic abscess is rare and most commonly occurs as a complication of acute prostatitis. Because of the wider use of antibiotics, the clinical presentation is becoming less typical. Diagnosis is useful for diagnosis. Based on a review of 3 cases, the authors report their experience with US-guided transrectal drainage of prostatic abscesses and review other therapeutic options.

The simultaneous presence of primary carcinomas in the same patient is uncommon and synchronous primary tumors involving the kidney and pancreas are extremely rare. There are a few reports in the eng literature of synchronous primary malignancies of the kidney and pancreas. We present a 62-year-old man who had weight loss of 9 kg and epigastric pain. Findings showed a Furhman grade II renal papillary carcinoma confined to the kidney and a synchronous well differentiated pancreatic ductal adenocarcinoma

OBJECTIVE: To assess prospectively the results of percutaneous sclerotherapy with povidone-iodine of symptomatic renal cysts in adults. METHODS: Fifty two patients were included in this study from august 2004 to november 2006. The operative indication was: pain (41 cases), urinary tract compression (8 cases), and very large cyst (3 cases). The preoperative assessment (site and dimensions of the cyst) always included ultrasonography. CT scan, for morphological assessment, was performed in 39 cases. RESULTS: The mean age of patients was 63 years (47-75 years). The mean diameter was 76 mm. The cysts were punctured in all the cases directly under local anaesthesia and guided by sonography. The procedure was very well tolerated in every case, with external drainage for 72 hours. Clinical regression was complete in 48 cases (92%), with total ultrasonographic disappearing of the cysts in 31 cases (60%) with a mean follow-up of 14 months (3-29 months). CONCLUSION: Percutaneous sclerotherapy with povidone-iodine is a safe, effective and reproducible treatment of symptomatic renal cysts in adults.
