INTRODUCTION:Erectile dysfunction (ED) is a common disorder that has many potential etiologies, including hormonal imbalances, psychogenic factors, neurologic disorders, vascular insufficiency, and other risk factors. Cigarette smoking has been well established as a risk factor for cardiovascular disease and stroke, but the relation between smoking and ED is less frequently considered. AIM:To review the current literature that analyzes the association between cigarette smoking and ED. METHODS:The PubMed database was searched using the terms erectile dysfunction and smoking and erectile dysfunction and tobacco through December 2015. MAIN OUTCOME MEASURES:Main outcome measures were significant changes in erectile function in relation to smoking status. RESULTS:Eighty-three studies and articles were reviewed. Multiple human studies, animal studies, case series, cross-sectional, and cohort studies analyzed the relation between smoking or nicotine and ED. CONCLUSION:There is substantial evidence showing that cigarette smoking is a risk factor for ED. Multiple human, animal, case series, cross-sectional, and cohort studies support this conclusion. A positive dose-response relation also is suggested such that increased quantity and duration of smoking correlate with a higher risk of ED. Smoking cessation can lead to recovery of erectile function, but only if limited lifetime smoking exposure exists. Smoking contributes to ED in different ways, especially by causing penile vasospasm and increased sympathetic nervous system tone.

In August 2015, an expert colloquium commissioned by the Sexual Medicine Society of North America (SMSNA) convened in Washington, DC, to discuss the common clinical scenario of men who present with low testosterone (T) and associated signs and symptoms accompanied by low or normal gonadotropin levels. This syndrome is not classical primary (testicular failure) or secondary (pituitary or hypothalamic failure) hypogonadism because it may have elements of both presentations. The panel designated this syndrome adult-onset hypogonadism (AOH) because it occurs commonly in middle-age and older men. The SMSNA is a not-for-profit society established in 1994 to promote, encourage, and support the highest standards of practice, research, education, and ethics in the study of human sexual function and dysfunction. The panel consisted of 17 experts in men's health, sexual medicine, urology, endocrinology, and methodology. Participants declared potential conflicts of interest and were SMSNA members and nonmembers. The panel deliberated regarding a diagnostic process to document signs and symptoms of AOH, the rationale for T therapy, and a monitoring protocol for T-treated patients. The evaluation and management of hypogonadal syndromes have been addressed in recent publications (ie, the Endocrine Society, the American Urological Association, and the International Society for Sexual Medicine). The primary purpose of this document was to support health care professionals in the development of a deeper understanding of AOH, particularly in how it differs from classical primary and secondary hypogonadism, and to provide a conceptual framework to guide its diagnosis, treatment, and follow-up.

INTRODUCTION:Despite recent advances in our knowledge and treatment strategies in Peyronie's Disease (PD), much remained unknown about this disease. AIM:To provide a clinical framework and key guideline statements to assist clinicians in an evidence-based management of PD. METHODS:A systematic literature search was conducted to identify published literature relevant to PD. The search included all relevant articles published up to June 2015, including preclinical studies and published guidelines. References used in the text were assessed according to their level of evidence, and guideline recommendations were graded based on the Oxford Centre for Evidence-Based Medicine Levels of Evidence. Owing to the paucity of larger series and randomized placebo-controlled trials with regard to surgical intervention, guideline statements are provided as clinical principle or expert opinion. MAIN OUTCOME MEASURES:This literature was discussed at a panel meeting, and selected articles with the highest evidence available were used to create consensus guideline statements for the Fourth International Consultation on Sexual Medicine guidelines on PD. RESULTS:In addition to existing Third International Consultation on Sexual Medicine guidelines on PD, seven new summary recommendations were created. CONCLUSION:A greater understanding of the scientific basis of PD is greatly needed to address our understanding of the pathophysiology, clinical epidemiology, psychosocial, and diagnostic assessment as well as treatment strategies.

Introduction: Medical malpractice and prostate cancer screening are important issues in the current landscape of health care. We identified factors contributing to litigation in the diagnosis of prostate cancer. Methods: We used the Westlaw® database to search for jury verdict reports using the term medical malpractice combined with prostate cancer with dates ranging from January 2000 to December 2013. Each case was examined for trial year, patient age, prostate specific antigen at alleged breach of duty and at diagnosis, defendant specialty, alleged cause of malpractice, whether there was metastasis, the outcome of cases that went to trial or were otherwise settled, and the plaintiff award. Results: The initial search produced 256 results, which was narrowed to 106 cases. Of these cases 64.1% went to trial, including 66.2% that were decided for the defendant. The mean out of court settlement was $945,000, significantly lower than the mean plaintiff verdict award of $2.1 million (p = 0.0009). Primary care physicians (74.1%) were the most commonly named defendants, followed by urologists (19.6%). The most common cause was failure to perform an initial prostate specific antigen test (26.8%), followed by failure to follow elevated prostate specific antigen (22.3%). Conclusions: Causes of malpractice revolved mostly around prostate specific antigen testing. Primary care physicians and urologists must continue to educate patients to minimize malpractice claims made in this setting. It will be important to follow data to see trends following recent guidelines.

Scrotal pain is a common complaint in a urological practice. Its diagnosis can prove challenging in both acute and chronic forms and requires a thorough and complete history and physical examination. This article discusses the evaluation and management of several entities of scrotal pain, including testicular torsion, epididymitis, postvasectomy pain, varicocele, and chronic orchialgia.
