HER-2/neu has been linked to the clinical progression of hormone independent prostate cancer. We performed a meta-analysis to investigate the prognostic impact of HER-2/neu over expression in patients with prostate adenocarcinoma, and its correlation with other pathological and clinical variables. We searched the MEDLINE, Embase, CancerLit and ASCO abstract databases for published studies of HER-2/neu protein expression in primary prostate cancer tissue with a median followup of greater than 2 years and data on survival in patients with and without HER-2/neu over expression. We separately analyzed studies reporting HER-2/neu soluble receptor levels in patients with prostate cancer. We included 38 articles with a total of 5,976 patients. The overall RR of death in those with HER-2/neu over expression in the primary tumor was 1.63 (95% CI 1.47-1.82, p <0.0001). In the presence of over expression the recurrence RR was 1.87 (95% CI 1.59-2.21, p <0.0001). High HER-2/neu extracellular domain levels also correlated with death (RR 2.01, 95% CI 1.21-3.35, p = 0.007) and recurrence (RR 1.74, 95% CI 1.41-2.15, p <0.0001). There is a consistent association of HER-2/neu over expression and Gleason less than 7 with a higher RR of death and recurrence in patients with prostate cancer. Further clinical trials should test the hypothesis that HER-2/neu is a marker of a clinically worse outcome in patients with prostate cancer and a potential target for therapy.

Objetive: Several biomarkers of ovarian reserve have been proposed as possible predictors of the response to controlled ovarian stimulation (COS). We aimed to evaluate age, FSH, AMH, antral follicle count (AFC), and ovarian response prediction index (ORPI), as potential predictors of response to COS. Methods: Cross-sectional study enrolling of 188 infertile women who underwent the first cycle of IVF/ICSI. AFC was evaluated; serum FSH and AMH levels were measured by ELISA. ORPI was calculated as AMH x AFC/patient´s age. Results: As expected, hypo-responder group had less retrieved oocytes, MII, and embryos compared to the good responders. The hyper-response patients were younger, with lower FSH, increased AMH, AFC, and ORPI values. Regarding the assessment of the predictive capacity of ovarian reserve tests, none of them individually or combined showed a good predictive capacity for hypo-response. With respect to the hyper-responder group, individually AMH was the best predictor, while in the multivariable model, ORPI demonstrated the best predictive capacity. Furthermore, patients with serum AMH < 2.09 ng/mL (p25) had fewer AFC than patients with higher AMH values. Conclusions: Our findings suggest that none of the ovarian reserve tests showed a good predictive capacity for hypo-response, while the ORPI was the strongest predictor of hyper-response in normovulatory infertile women.

Acne in adult women is a hard-to-manage frequent disease with many relapse cases. It mostly interferes with quality of life and causes major social and metabolic losses for patients. This is a transversal retrospective study and the aim was to standardize the research on circulating androgenic hormone levels and to detect hyperandrogenic states early, showing the frequency and the pattern of the altered hormones, useful resources to correctly evaluate each patient. In this study 835 women above 15 years of age, with acne or aggravation cases, were analyzed. The aim was to verify the percentage of androgen examinations with levels above normal. The levels of the hormones dehydroepiandrosterone sulfate, dehydroepiandrosterone (DHEA), dehydrotestosterone, androstenedione and total testosterone were measured in all patients. The evaluation of the hormone profile showed that 54.56% of the patients had hyperandrogenism, and the levels of DHEA were most frequently elevated. Therefore, in the face of the importance of hyperandrogenism in the pathogenesis of acne, standardizing the research of the hormone profile is paramount for the treatment and control of relapses in case of a surge of acne breakouts during a woman's adult life.

Background: Alopecia areata is the hair loss usually reversible, in sharply defined areas. The treatment of alopecia using growth factors shows interesting activity in promoting hair growth. In this concept, VEGF (vascular endothelial growth factor) is a marker of angiogenesis, stimulating hair growth by facilitating the supply of nutrients to the hair follicle, increasing follicular diameter. The aim of this study was the evaluation of a topical gel enriched with VEGF liposomes on the hair growth stimulation and its toxicological aspects. Methods: Mesocricetus auratus were randomly divided into three groups. Control group was treated with Aristoflex® gel, 1% group with the same gel but added 1% VEGF and 3% group with 3% VEGF. Biochemical, hematological and histological analyses were done. Results: At the end of the experiment (15th day of VEGF treatment) efficacy was determined macroscopically by hair density dermatoscopy analysis, and microscopically by hair diameter analysis. They both demonstrated that hair of the VEGF group increased faster and thicker than control. On the other hand, biochemical and hematological results had shown that VEGF was not 100% inert. Conclusions: VEGF increased hair follicle area, but more studies are necessary to confirm its toxicity.
