Male infertility: lifestyle factors and holistic, complementary, and alternative therapies.

While we may be comfortable with an allopathic approach to male infertility, we are also responsible for knowledge about lifestyle modifications and holistic, complementary, and alternative therapies that are used by many of our patients. This paper provides an evidence-based review separating fact from fiction for several of these therapies. There is sufficient literature to support weight reduction by diet and exercise, smoking cessation, and alcohol moderation. Supplements that have demonstrated positive effects on male fertility on small randomized controlled trial (RCT) include aescin, coenzyme Q 10 , glutathione, Korean red ginseng, L-carnitine, nigella sativa, omega-3, selenium, a combination of zinc and folate, and the Menevit antioxidant. There is no support for the use of Vitamin C, Vitamin E, or saffron. The data for Chinese herbal medications, acupuncture, mind-body practice, scrotal cooling, and faith-based healing are sparse or inconclusive.

Diagnosis of relevant prostate cancer using supplementary cores from magnetic resonance imaging-prompted areas following multiple failed biopsies.

OBJECTIVES: To establish the value of MRI in targeting re-biopsy for undiagnosed prostate cancer despite multiple negative biopsies and determine clinical relevance of detected tumors. MATERIALS AND METHODS: Thirty-eight patients who underwent MRI after 2 or more negative biopsies due to continued clinical suspicion and later underwent TRUS-guided biopsy supplemented by biopsy of suspicious areas depicted by MRI were identified. Diagnostic performance of endorectal 3T MRI in diagnosing missed cancer foci was assessed using biopsy results as the standard of reference. Ratio of positive biopsies using systematic versus MRI-prompted approaches was compared. Gleason scores of detected cancers were used as surrogate for clinical relevance. RESULTS: Thirty-four percent of patients who underwent MRI before re-biopsy had prostate cancer on subsequent biopsy. The positive biopsy yield with systematic sampling was 23% versus 92% with MRI-prompted biopsies(p<0.0001). Seventy-seven percent of tumors were detected exclusively in the MRI-prompted zones. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of MRI to provide a positive biopsy were 92%, 60%, 55%, 94% and 71%, respectively. The anterior gland and apical regions contained most tumors; 75% of cancers detected by MRI-prompted biopsy had Gleason score≥7. CONCLUSIONS: Clinically relevant tumors missed by multiple TRUS-guided biopsies can be detected by a MRI-prompted approach.

Quality of life in children with vesicoureteral reflux as perceived by children and parents.

PURPOSE: Significant research has been dedicated to the management of vesicoureteral reflux (VUR). However, few studies have been published to evaluate the impact of this disease on quality of life. The aim of this study was a prospective examination of the health-related quality of life (HRQoL) in children with VUR who have either been treated medically (antibiotics or surveillance) or by ureteral reimplant (UR) using a validated patient satisfaction survey. MATERIALS AND METHODS: A prospective, longitudinal study was conducted using a validated HRQoL questionnaire, the Pediatric Quality of Life Inventory (PedsQL™ 4.0 Generic Core). 353 children or parents of children with VUR, age 2-18 years, completed the survey. Statistical analysis was performed with significance set at p-value ≤ 0.05. RESULTS: Children and parents of children with VUR did not score lower on total or subscale domains of HRQoL when compared to a historical healthy control. On univariate analysis, patients who underwent UR scored lower on total as well as physical, social, and school subscale HRQoL domains, compared to patients managed medically. When controlling for gender, ethnicity, age, reflux grade, and antibiotic use, there was no difference in total HRQoL between patients who underwent UR compared to those managed medically. CONCLUSIONS: In terms of HRQoL, VUR is a benign clinical entity and neither antibiotic use nor UR is associated with lower HRQoL. Disease-specific quality of life surveys are needed to accurately evaluate patient and parent satisfaction in the management of VUR.
