subgroups were comparable in age, body mass index, preoperative prostate-specific antigen level, preoperative Gleason score, clinical stage, operative duration, length of hospital stay, duration of catheterization, biochemical recurrence and continence after LRP. In the patients with a prostate of ≤ 30 g there was a higher incidence of positive margins (39% vs 16% vs 27%; P = 0.03) and inferior 1-year potency (47% vs 75% vs 79%; P = 0.04), respectively. Estimated blood loss increased with increasing prostate size (204 vs 256 vs 340 mL; P = 0.01). CONCLUSIONSProstate size has no effect on continence or biochemical recurrence at 1 year after LRP, but affects intraoperative blood loss, potency and surgical margins. More patients with a longer follow-up are needed to confirm these findings.

Primary mucinous adenocarcinoma is an extremely rare type of bladder cancer, with aggressive behavior and poor response to chemotherapy and radiotherapy. The symptoms are similar to those of other bladder tumors. Surgery is the main treatment and remains the only curative option. There may be a progression from mucinous metaplasia to mucinous adenoma and then mucinous adenocarcinoma. We present the case of a 40-year-old woman with recurrent lower urinary tract infections, submitted to imaging tests, which showed a bladder tumor. After transurethral resection, pathology showed intestinal mucinous carcinoma. Metastatic work-up was negative. New surgical procedure showed metaplasia but no recurrence of the carcinoma. The patient is now using antibiotic prophylaxis and will undergo a cystoscopy every 3 months and computed tomography in one year.

Ruptura dos órgãos que constituem o tubo digestório pode ocorrer em presença de aumento tensórico intraluminar ou quando sua parede estiver enfraquecida. É possível que as diferenças histológicas entre as diversas partes desse tubo interfiram na pressão necessária para que ocorra sua ruptura. Acredita-se que o uso prolongado de corticosteróides possa diminuir a resistência da parede digestória. Com o objetivo de se avaliarem as pressões de ruptura dos órgãos pertencentes ao tubo digestório, realizou-se o presente trabalho. Foram utilizados 20 camundongos de ambos os sexos, com peso variando entre 38 e 52 g, divididos aleatoriamente em dois grupos (n=10): grupo sem corticóide e grupo com administração subcutânea de hidrocortisona (1mg/kg/dia) durante 28 dias. Após esse período, os camundongos foram mortos e, em seguida, foram retirados os diversos segmentos do tubo digestório correspondentes a seus órgãos para avaliação da tensão de ruptura. Não houve diferença significativa entre os grupos com e sem corticóide. As tensões de ruptura do esôfago e do cólon foram maiores do que a do estômago, duodeno, jejuno e íleo (p<0,05). Concluindo, a administração de corticosteróide durante 28 dias não altera a resistência à ruptura do tubo digestório íntegro. O esôfago e o cólon apresentaram maior resistência à ruptura que os demais segmentos digestórios. A resistência do esôfago é significativamente maior que a do cólon.

We report a rare case of a primary synovial sarcoma of the pericardium. Surgical resection was incomplete and chemotherapy and radiotherapy (tomotherapy) were therefore administered. Regular cardiac magnetic resonance imaging scans were used throughout the follow-up, allowing effective planning and application of adjuvant therapies. The survival of our patient was 26 months, substantially longer than most previously reported cases.
