Perianal streptococcal dermatitis (PSD) is an uncommon superficial cutaneous infection of the perianal area, almost exclusively described in children and mainly caused by group A streptococci. We report here a case of PSD caused by Streptococcus dysgalactiae subsp. equisimilis, Lancefield group G, in an adult man due to heterosexual oral-anal sexual contact.
Clinicians need to be aware of cutaneous amoebiasis in sexually active men who practice unprotected insertive anal sex where intestinal amoebiasis is endemic. Wet mount microscopy is a rapid and useful diagnostic test.
A case of heterosexual transmission of Moraxella catarrhalis by fellatio, which resulted in acute purulent urethritis mimicking gonorrhoea in the male partner, is described. In male patients with urethritis due to M. catarrhalis, orogenital contact with a sexual partner carrying the organism in his/her oropharynx is the probable route of transmission.
Is unprotected insertive anal sex a predisposing factor in causing sexually transmitted urinary tract infection in men?Sirs: We read with interest the article by Ashby and Smith 1 describing a simultaneous case of urinary tract infection (UTI) in a male homosexual couple caused by an identical uropathogenic strain of Escherichia coli. Sexual transmission following unprotected insertive anal sex was proposed as a probable route of transmission. We agree with authors that the causative role unprotected insertive anal sex may play in the sexual acquisition of UTI among men is not well documented.Sexual transmission of UTIs has not been previously described in Iran; a retrospective case-notes review was undertaken for all adult and sexually active men attending a single private medical sector with special interest in dermatovenereology in Tehran, Iran (January 2005-December 2010).Of the 415 men with a recent episode of UTI, 81 (19.5%) disclosed that they had symptoms after practicing unprotected insertive anal sex, whereas 334 (80.5%) denied any anal intercourse preceding onset of UTI symptoms. We have observed a general increase in the number of symptomatic cases of acute cystitis among previously healthy, young and sexually active heterosexual men aged between 18 and 45 years (mean age: 27.9 years) who had engaged in unprotected insertive anal sex prior to a recent episode of UTI. The total number of men with UTI who disclosed unprotected insertive anal sex was seven out of 52 (13.5%) in 2005, while 23 out of 83 men (27.7%) reported the same practice in 2010 (Table 1). Fisher's exact test for proportions was used to compare the number of cases out of the totals between 2005 and 2010. The difference between the two proportions approached significance (95% confidence interval [CI] 0.009-0.276, P ¼ 0.058). Among men with UTI who practiced unprotected insertive anal sex, urinary tract abnormalities were absent and none had a history of sexually transmitted infections (STIs) or recent UTI. Interestingly, unprotected insertive anal sex has been commonly reported by our cases, which was the likely risk factor for the UTI that ensued. E. coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Enterococcus spp. were most frequent isolates.Anal sex, even among married heterosexual couples, is both socially and culturally stigmatized, and therefore subject to underreporting in Iran. It is generally accepted that anal sex is practiced at relatively low rates among heterosexual men and women in our country; however, recent trends towards open relationships, particularly among young unmarried couples in inner cities, have changed this picture. Several motivations such as maintenance of vaginal virginity and/or avoidance of unwanted pregnancy may explain the preference for anal over vaginal intercourse, particularly among young unmarried couples. 2 Noteworthy, among heterosexual couples who engage in protected vaginal but unprotected anal sex, condoms are more likely to be used as contraception and not to prevent STI transmission...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
