Background. Little is known about the role of asymptomatic bacteriuria (AB) treatment in young women affected by recurrent urinary tract infection (UTI). We aimed to evaluate the impact of AB treatment on the recurrence rate among young women affected by recurrent UTI. Methods. A total of 673 consecutive asymptomatic young women with demonstrated bacteriuria from January 2005 to December 2009 were prospectively enrolled. Patients were split into 2 groups: not treated (group A, n = 312) and treated (group B, n = 361). Microbiological and clinical evaluations were performed at 3, 6, and 12 months. Quality of life was also measured. Recurrence-free rate at the end of the entire study period was the main outcome measure. Results. At baseline, the 2 most commonly isolated pathogens were Escherichia coli (group A, 38.4%; group B, 39.3%) and Enterococcus faecalis (group A, 32.7%; group B, 33.2%). At the first follow-up visit, there was no difference between the 2 groups (relative risk [RR], 1.05; 95% confidence interval [CI], 1.01–1.10), whereas after 6 months, 23 (7.6%) in group A and 98 (29.7%) in group B showed recurrence with a statistically significant difference (RR, 1.31; 95% CI, 1.21–1.42; P < .0001). At the last follow-up, 41 (13.1%) in group A and 169 (46.8%) in group B showed recurrence (RR, 3.17; 95% CI, 2.55–3.90; P < .0001). One patient in group A and 2 patients in group B were found to have pyelonephritis. Conclusions. This study shows that AB should not be treated in young women affected by UTI, suggesting it may play a protective role in preventing symptomatic recurrence.

The efficacy and tolerance of the nonsteroidal antiandrogen nilutamide in the treatment of prostatic cancer were studied in a large double-blind clinical trial initiated in 1986. Patients with metastatic prostatic cancer without prior endocrine manipulation underwent orchiectomy and were randomized to 1 of 2 groups receiving nilutamide (225 patients) or placebo (232). Nilutamide and placebo were evaluated for efficacy in 207 and 216 patients, respectively. Progression-free survival was significantly longer in the nilutamide group (median time to progression 20.8 months on nilutamide and 14.9 months on placebo, p = 0.005). Median time to death from prostatic cancer was 30.0 months in the placebo group and 37 months in the nilutamide group. Objective regressions were higher in the nilutamide group (41%) than in the placebo group (24%). Significant differences in favor of the nilutamide group were found at several intervals for bone pain, prostatic acid phosphatase, prostate specific antigen, alkaline phosphatase and bone scan isotope uptake. Nilutamide and orchiectomy constitute a more effective treatment for metastatic prostatic cancer than orchiectomy alone, and the adverse effects of nilutamide, usually minor, are outweighed by the significant improvements in most disease measures and progression-free survival.

We evaluated the prevalence and estimated the incidence and risk factors of chronic prostatitis/chronic pelvic pain syndrome in urological hospital outpatients in Italy. From January to June 2006 patients from 28 Italian urological centers who were between 25 and 50 years old with symptoms of chronic prostatitis/chronic pelvic pain syndrome were consecutively enrolled in this prospective epidemiological case-control study. A total of 152 subjects of similar age, race and area of origin who were investigated for infertile couples but were otherwise healthy served as controls. All subjects provided a medical history and underwent different symptom scorings, clinical evaluation and microbiological tests. Of 5,540 male urological outpatients 764 with chronic prostatitis/chronic pelvic pain syndrome were enrolled, including 225 (29.4%) at the first presentation and 539 (70.6%) who underwent previous treatment. Thus, the prevalence of the syndrome was 13.8%, while the estimated incidence was 4.5%. Cigarette smoking, a high caloric diet with low fruit and vegetable consumption, constipation, meteorism, slow digestion, a sexual relationship with more than 1 partner and coitus interruptus were more likely in patients with chronic prostatitis/chronic pelvic pain syndrome than in controls (each p <0.001). The syndrome had a negative influence on sexual desire, erectile dysfunction and premature ejaculation (p <0.001). The Meares and Stamey test was positive in 13.3% of patients and in 2.9% of controls. Urethral swabs in patients with a negative Meares and Stamey test were positive for sexually transmitted pathogens in 6%. The prevalence and estimated incidence of chronic prostatitis/chronic pelvic pain syndrome in urological hospital outpatients in Italy are high. The syndrome is closely related to lifestyle, diet, smoking, gastrointestinal or anorectal disease and impaired sexual function.
