Intermittent androgen suppression in patients with prostate cancer

To evaluate intermittent androgen suppression (IAS) in patients with prostate cancer and to try to define predictive factors for biochemical progression.

Prosbiotate: A Multicenter, Prospective Analysis of Infectious Complications after Prostate Biopsy

PURPOSE Prostate biopsy side effects have a role in the controversy over screening for prostate cancer. We measured the precise incidence of infection after prostate biopsy and determined risk factors. MATERIALS AND METHODS We performed a prospective, multicenter study in France from April to June 2013. All prostate biopsies done during this period were included in study. A web based questionnaire was used to identify patient characteristics, biopsy methods and postoperative infectious episodes. External audit helped ensure data completeness. The primary outcome was the post-biopsy infection rate. We determined risk factors for infectious complications using univariate and multivariate analysis. RESULTS The study included 2,718 patients, of whom 6% reported receiving antibiotics in the previous 6 months and 7.4% had a history of prostatitis. Recommended antibiotic prophylaxis consisting of 2 fluoroquinolone tablets 2 hours before examination for prostate biopsy was noted in 78.3% of cases. Post-biopsy sepsis was found in 76 subjects (2.8%). On multivariate analysis predictors of post-biopsy sepsis were noncompliance with antibiotic prophylaxis guidelines (OR 2.3, 95% CI 1.4-3.9, p = 0.001), antibiotic treatment in the previous 6 months (OR 2.1, 95% CI 1.1-3.9, p = 0.015) and a history of prostatitis (OR 1.7, 95% CI 1.2-2.4, p = 0.002). CONCLUSIONS In this study the incidence of post-prostate biopsy sepsis was 2.8% and no deaths were reported. Risk factors identified on multivariate analysis were noncompliance with antibiotic prophylaxis according to guidelines, antibiotic treatment in the previous 6 months and a history of prostatitis.

Synthèse des recommandations pour le traitement de l’incontinence urinaire féminine non neurologique

Resume Ces deux dernieres decennies ont permis de voir apparaitre de nouveaux traitements medicaux ou chirurgicaux revolutionnant la prise en charge de l’incontinence urinaire feminine non neurologique. De nombreuses etudes souvent prospectives randomisees, avec des reculs suffisants, ont permis de valider les bons choix therapeutiques en dehors des effets de mode et des pressions commerciales. L’Association Francaise d’Urologie, par le biais de son Comite d’Urologie et de Pelviperineologie de la Femme, propose ses recommandations. Celles-ci ont ete etablies par un groupe d’experts des specialites concernees (Urologues, Gynecologues, Reeducateurs), a partir d’une revue de la litterature, mais en tenant compte des pratiques quotidiennes universitaires et liberales. Entre Evidence Base Medicine et realite du terrain, ces recommandations essayent de proposer des attitudes realistes et applicables.

Localized Hyperthermia Versus the Sham Procedure in Obstructive Benign Hyperplasia of the Prostate: A Prospective Randomized Study

Hyperthermia was shown to cause improvement in 50 to 60% of the patients with benign prostatic hyperplasia (BPH) without considering placebo effects. We studied 68 patients randomly assigned to a treatment group (38) and a sham group (30) who underwent the same manipulation but without applying radio frequency power. The Biodan Prostathermer was used. Criteria for inclusion were based on objective and subjective symptoms. Treatment was performed 6 times at 43 +/- 0.5C for the treatment group. Followup evaluation was performed at 3 months, and the same objective and subjective symptoms were recorded. We observed a statistically significant subjective improvement in the sham group (33%) that was not accompanied by any significant objective improvement. In the treatment group the subjective response was significantly better regarding number of patients (68%) and response rate, and was substantiated by a significant improvement in all objective symptoms (53% of the patients) except voided volume. Therefore, hyperthermia treatment had a definite therapeutic effect on BPH in excess of placebo.

Recommandations de bonnes pratiques cliniques : antibioprophylaxie et neuromodulation des racines sacrées par le Comité d’infectiologie de l’Association française d’urologie (CIAFU) et le Comité de neuro-urologie de l’AFU

INTRODUCTION In urology, antibiotic prophylaxis is advised by the French Association of anesthesiology (SFAR) and the Infectious Disease Committee of the French Association of urology guidelines published in 2010. No guideline exists concerning the implantation of neuromodulation implants. MATERIAL AND METHOD A literature analysis was performed on sacral modulation and antibiotic prophylaxis. Then guidelines were discussed by reviewers. Items that showed no consensus were then discussed again to arrive at recommendations. RESULTS Antibiotic prophylaxis is recommended during the test phase as well as in the case of installation of sacral neuromodulation (Grade C). Antibiotic recommended (Grade B) are: cefotetan or cefoxitin, 2g dose by slow intravenous injection or amoxicillin-clavulanic acid at a dose of 2 g, intravenously or, in the case of allergy vancomycin at a dose of 15 mg/kg or the clindamycin has 600 mg intravenously. CONCLUSIONS Despite the lack of high level of evidence, antibiotic prophylaxis seems necessary when setting up of electrode case of sacral neuromodulation.

Tumeurs rénales hybrides : à propos de deux patients

PURPOSE Renal hybrid tumors (HT) are characterized by the association of both oncocytes- and chromophobe-cells within the same tumor. They have been reported in patients with Birt-Hogg-Dube (BHD) syndrome. The aim of this report was to describe two cases of HT and summarize recent literature. PATIENT AND METHOD Case study was summarized from the patients medical chart. Review of literature was performed using the National Center for Biotechnology Information (NCBI) database. RESULTS Two patients were diagnosed with multiple but small tumors of the kidney, and were treated with partial nephrectomy. Pathological analysis of these tumors showed oncocytoma-like and chromophobe-like cells intermixed in the same stroma. CONCLUSIONS HT may constitute a spectrum of tumors between renal oncocytoma and chromophobe renal cell carcinoma. From a pragmatic management perspective, it would be appropriate to consider such tumors as chromophobe carcinoma. In case of HT, a genetic study for BHD syndrome can be proposed to family relatives.

Étude Prosbiotate : étude prospective analytique des prostatites post biopsies de la prostate : analyse intermédiaire de plus de 1200 biopsies

La colistine et les imipeneme gardent leur efficacite avec un taux de resistance inferieur a 10%. Les germes presentant une betalactamase a spectre Elargi (BLSE) representent la grande majorite, temoin des prescriptions abusifs, et des conditions de sondage et de soins de sonde. Conclusion.— Il devient necessaire de revoir les protocoles de sondage, de prendre en compte l’epidemiologie locale des resistances bacterienne lors de la prescription des antibiotiques, et de rationaliser cette prescription afin de diminuer le risque de developpement des resistances.
