Hard flaccid syndrome (HFS) is a rather rare, acquired clinical entity affecting young men’s well-being, sexual and social life. HFS presents with a cluster of symptoms including penile-specific somatosensory disturbances, a semi-rigid penis at the flaccid state without any stimulation or desire, erectile dysfunction, perineal and/or penile pain, associated urinary symptoms, emotional distress as well as other psychosocial and stress-related manifestations. Although its pathophysiology is still not well understood, initial penile trauma causing minor nerve and vascular disturbances to the penis and associated pelvic floor musculature is suggested to trigger the syndrome. Despite the scarcity of research on HFS, the present report describes a case of a young male clinically diagnosed with HFS, who benefited from a biopsychosocial management strategy, focusing on pain management, therapeutic exercise approaches, such as pelvic floor exercise re-education, graded exposure to activity as well as education on lifestyle and stress-related modifications. This holistic management approach has been clinically reasoned in this case report, and the need for more evidence-based studies developing diagnosing criteria, elaborating pathophysiological mechanisms and testing the efficiency of different therapeutic options is highlighted.

Inflatable penile prosthesis (IPP) surgery is an effective treatment for erectile dysfunction (ED), but infections pose a significant threat to its success. Current guidelines lack antifungal recommendations, despite rising fungal infection rates post-IPP surgery. This review examines epidemiology, risk factors (including diabetes mellitus, immunosuppression, and obesity), and pathogenesis, highlighting the role of biofilm formation in device contamination. Clinical manifestations vary from acute to delayed, with fungal biofilms presenting challenges in diagnosis. Prophylactic strategies, including broad-spectrum antibiotics and antifungals, are crucial, with evidence suggesting a 92% reduction in infections. With fungal infections showing lower salvage rates, management involves culture-guided treatment, irrigation, and oral antibiotics. Future research aims to understand biofilm mechanisms and develop biomaterials to reduce infection rates. Implementing antifungal therapy, along with standard practices like the no-touch technique and antibiotic dips, is crucial in preventing IPP infections.

PURPOSE Prostate cancer patients are a heterogeneous group concerning the aggressiveness of the disease. The relationship of steroid hormones with the aggressiveness of prostate cancer is unclear. It is known that the Anti-Müllerian Hormone (AMH), inhibits prostate cancer cell lines in vitro. The aim of this study is to investigate the relationship of AMH and steroid hormones with the aggressiveness of prostate cancer.METHODS This was a prospective study of consecutive radical prostatectomy patients. We measured the following hormones: total testosterone, sex hormone binding globulin, albumin, luteinizing hormone, follicle stimulating hormone, estradiol, dehydroepiandrosterone sulfate, androstenedione and AMH. The minimum follow-up after radical prostatectomy was 5 years. For the aggressiveness of prostate cancer, we considered the following 3 variables: post-operative Gleason Score (GS) ≥ 8, TNM pΤ3 disease and PSA biochemical recurrence (BCR).RESULTS In total, 91 patients were enrolled. The mean age and PSA was 64.8 years and 9.3 ng/dl, respectively. The median post-operative GS was 7. Low AMH blood levels were correlated with higher post-operative GS (p = 0.001), as well as with PSA BCR (p = 0.043). With pT3 disease, only albumin was (negatively) correlated (p = 0.008). ROC analysis showed that AMH is a good predictor of BCR (AUC 0.646, 95% CI 0.510–0.782, p = 0.043); a cut-off value of 3.06 ng/dl had a positive prognostic value of 71.4% and negative prognostic value of 63.3% for BCR. Cox regression analysis showed that AMH is a statistically significant and independent prognostic marker for BCR (p = 0.013). More precisely, for every 1 ng/ml of AMH rise, the probability for PSA BCR decreases by 20.8% (HR = 0.792). Moreover, in Kaplan-Meier analysis, disease-free survival is more probable in patients with AMΗ ≥ 3.06 ng/ml (p = 0.004).CONCLUSIONS Low AMH blood levels were correlated with aggressive prostate cancer in this radical prostatectomy cohort of patients. Therefore, AMH could be a prognostic biomarker for the aggressiveness of the disease.
