Unilateral adrenal hyperplasia with primary aldosteronism is very rare and shows similar endocrine features to aldosterone-producing adenoma and bilateral adrenal hyperplasia. In this study, the mRNA expression of steroidogenic enzymes in unilateral adrenal hyperplasia was examined by in situ hybridization. We found subcapsular micronodules composed of spironolactone body-containing cells, which showed intense expression for 3beta-hydroxysteroid dehydrogenase, 11beta-hydroxylase, 18-hydroxylase, and 21-hydroxylase but not 17alpha-hydroxylase, indicating aldosterone production. This expression pattern was the same as that in unilateral multiple adrenocortical micronodules, reported recently. Additionally, it was noted that a nodule with active aldosterone production was closely adjacent to one showing intense 17alpha-hydroxylase expression. In the adrenal cortices adhering to aldosterone-producing adenoma, the majority of hyperplastic zona glomerulosa and hyperplastic nodules demonstrated a decreased steroidogenic activity. However, minute nodules indicative of active aldosterone production were found at high frequency. These results suggest that the subcapsular micronodules observed might be the root of aldosterone-producing adenoma. Furthermore, we emphasize the need for long-term follow-up after unilateral adrenalectomy or enucleation of the adenoma because of the possibility that buds with autonomous aldosterone production may still be present in the contralateral or remaining adrenal tissue.

A case of acute hemorrhagic cystitis caused by adenovirus type 11 which occurred in an allograft recipient 6 months after a living-related renal transplantation, is described. The patient lacked a neutralizing antibody to adenovirus type 11 before transplantation. Adenovirus type 11 was isolated from his urine and he developed a neutralizing and complement-fixing antibody to this virus. Although adenovirus type 11 isolates had been obtained from 2 of 18 renal allograft recipients, only 1 patient suffered acute hemorrhagic cytitis. Adenovirus type 11 may play a role in acute hemorrhagic cystitis in renal allograft recipients during immunosuppressive therapy.

This analysis indicated that extended prophylactic maintenance instillation of EPI was not significantly effective in reducing bladder cancer recurrence.

Objectives:We conducted a prospective, randomized study to investigate hot flashes and quality of life (QOL) during combined androgen blockade (CAB) therapy using steroidal or nonsteroidal antiandrogens. Methods:A total of 151 patients with prostate cancer, enrolled into this study between May 2001and June 2003, were randomized to receive CAB therapy using an LHRH agonist (leuprorelin) combined with a steroidal antiandrogen (chlormadinone) or a nonsteroidal antiandrogen (bicalutamide). The incidence of, frequency of, and distress due to hot flashes were evaluated with a self-entry questionnaire over 2 years. General and disease-specific QOL outcomes were also measured with the Functional Assessment of Cancer Therapy-Prostate (FACT-P) questionnaire.Results: Data were available for analysis on 124 patients. Although the incidence of hot flashes largely tended to be higher in the bicalutamide group than in the chlormadinone group, no significant difference was noted in the cumulative incidence of hot flashes at 2 years. The median frequency of hot flashes per day was 1.3 and 2.2 for warmth/flushing (P = 0.16) and 1.0 and 3.6 for sweating (P = 0.021) in the chlormadinone and bicalutamide groups, respectively. Patients in the chlormadinone group were significantly less likely to be distressed due to warmth/flushing 4 (OR 0.47, P < 0.001) and sweating (OR 0.61, P = 0.01) than those in the bicalutamide group.The time course of FACT-P scores showed no inter-group differences. Conclusions:Our results suggest that CAB using a steroidal antiandrogen such as chlormadinone may induce fewer and less distressing hot flashes than CAB with bicalutamide.

We report a case of carcinosarcoma of the bladder. Total cystectomy with ileal loop urinary diversion was performed. Histologically, the bulk of the tumor tissue was rhabdomyosarcoma and adenocarcinoma. At distant areas from the bulk tumor transitional cell carcinoma was noted. The literature is reviewed and the clinicopathologic condition of carcinosarcoma of the bladder is discussed.
