Homosexuality is a global human phenomenon. Although the American Psychiatric Association removed homosexuality from its list of disorders more than 35. years ago, homophobia among physicians is still widely prevalent. Men who have sex with men (MSM) form a relatively new epidemiological risk group for STI. To perform correct management, clinicians evaluating men with male-male sex contacts for STI related complaints or STI screening must obtain a thorough sexual history. Emerging STI like lymphogranuloma venereum, hepatitis C, and multidrug resistant N. gonorrhea strains have been described first in MSM. STI related proctitis often occur in MSM. Within the MSM population, HIV positive patients form a special group affected by STI related diseases, such as anal carcinoma and neurosyphilis. The final part of this review concludes with recommendations to reduce the STI burden in MSM. © 2014 Elsevier Inc. Source

Objective: Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) is common among men who have sex with men (MSM) in the USA. It is unknown whether this is also the case in Amsterdam, the Netherlands. Design: Cross-sectional study. Setting: Sexually transmitted infection outpatient lowthreshold clinic, Amsterdam, the Netherlands. Participants: Between October 2008 and April 2010, a total of 211 men were included, in two groups: (1) 74 MSM with clinical signs of a skin or soft tissue infection (symptomatic group) and (2) 137 MSM without clinical signs of such infections (asymptomatic group). Primary outcome measures: S aureus and MRSA infection and/or colonisation. Swabs were collected from the anterior nasal cavity, throat, perineum, penile glans and, if present, from infected skin lesions. Culture for S aureus was carried out on blood agar plates and for MRSA on selective chromagar plates after enrichment in broth. If MRSA was found, the spagene was sequenced. Secondary outcome measures: Associated demographic characteristics, medical history, risk factors for colonisation with S aureus and high-risk sexual behaviour were collected through a selfcompleted questionnaire. Results: The prevalence of S aureus colonisation in the nares was 37%, the pharynx 11%, the perianal region 12%, the glans penis 10% and in skin lesions 40%. In multivariable analysis adjusting for age, anogenital S aureus colonisation was significantly associated with the symptomatic group (p=0.01) and marginally with HIV ( p=0.06). MRSA was diagnosed in two cases: prevalence 0.9% (95% CI 0.1% to 3.4%)). Neither had CA-MRSA strains. Conclusions: CA-MRSA among MSM in Amsterdam is rare. Genital colonisation of S aureus is not associated with high-risk sexual behaviour. Source
