Introduction: In this current perspective we analyzed the role of Mediterranean diet (MedDiet) in sexual function and particularly in erectile dysfunction (ED), according to the latest scientific evidence., Material and Methods: We conducted a systematic search of relevant full-length papers identified during the time period from 1 January 2010 to the present., Results: Published studies showed that adherence to a MedDiet contributes to preventing ED through an improved lipid and glucose metabolism, increased antioxidant defenses, and increased arginine levels which could raise nitric oxide activity., Conclusions: Our findings suggest that the encouragement of a healthy lifestyle, such as MedDiet promotion, could be an attractive dietary approach to prevent ED and preserve sexual function., Competing Interests: The authors declare no conflicts of interest.

A 36-year-old Caucasian man was diagnosed with a 72-h-lasting priapism that occurred after the assumption of a Herbal supplement based on Tribulus terrestris, which is becoming increasingly popular for the treatment of sexual dysfunction. The patient underwent a cavernoglandular shunt (Ebbehoj shunt) in order to obtain complete detumescence, from which derived negative post-episode outcomes on sexual function. All patients consuming non-FDA-approved alternative supplements such as Tribulus terrestris should be warned about the possible serious side effects.

Introduction: Epidemiologic studies have implicated obesity in prostate cancer (PCa) development and aggressiveness; nevertheless, no clear consensus has been reached. The aim of the research was to investigate the association of obesity with PCa, hormone-naïve at initial diagnosis., Methods: A retrospective analysis of 266 patients undergoing prostate biopsy at our institution, between 2006 and 2009, was conducted. We examined obesity and PCa association in 133 patients with PCa, hormone-naïve at initial diagnosis, versus 133 age-matched controls. Men with incomplete data available, a history of hormone therapy or chemotherapy, prostate or bladder surgery were excluded., Results: Obesity was significantly associated (OR 2.25) with aggressive PCa (Gleason score ≥7) and inversely related (OR 0.35) to non-aggressive PCa (Gleason score ≤6). Particularly, obesity in diabetic patients was significantly linked with aggressive PCa (OR 4.17). No association was noted between obesity and PCa development., Conclusions: In our study, obese patients, particularly in combination with diabetes mellitus (DM), were more likely to present with more aggressive PCa. Further research with larger samples should be done to confirm these associations and to stabilize future prevention strategies.

In this review we analyzed the role of PGE2 as a possible regulator of bone metabolism and bone metastases in prostate cancer. Published studies were identified by searching computerized bibliographic systems from January 1(st), 2000 to July 1(st), 2011. PGE2 represents a key factor in the modulation of bone metabolism and bone metastatic disease in prostate cancer interacting with bone regulatory signals including the RANK/RANKL/OPG system and Wnt pathways. A high concentration of PGE2 exerts a prevalent stimulatory effect on osteoclastogenesis via OPG/RANK/RANKL axis activation and a inhibitory effect on osteoblastogenesis trough inhibition of Wnt pathway. An inversely low level of PGE2 exerts a stimulatory effect on osteoblastogenesis via activation of the Wnt pathway. Our finding suggests that PGE2 acts as a regulator in maintaining normal bone mass and indicate a mechanism whereby chemical manipulation of PGE2 levels or signaling may be therapeutically beneficial for prostate cancer treatment.
