Acroangiodermatitis mimicking Kaposi's sarcoma in an HIV-positive man.

Kaposi's sarcoma (KS) is the commonest human immunodeficiency virus (HIV)-related malignancy with its characteristic cutaneous morphological appearance and histopathological features. However, it can be simulated by other co-morbid opportunistic infections and unrelated dermatological conditions. We describe such a case of acroangiodermatitis in an HIV co-infected man, based on exclusion of KS histologically and the absence of human herpesvirus 8, the causative agent of KS.

Evaluation of hepatitis C testing in men who have sex with men, and associated risk behaviours, in Manchester, UK.

OBJECTIVE: To determine the prevalence of newly diagnosed hepatitis C virus (HCV) and associated risk behaviours among men who have sex with men (MSM) in Manchester. METHOD: A survey among MSM attending four genitourinary medicine clinics in Manchester was carried out over 9 months in 2013. Participants were asked about recent sexual behaviour, recreational drug use and HIV status. All men were offered an HCV test. RESULTS: Overall, 2030 MSM completed a questionnaire and accepted an HCV test. Of whom, 0.9% (18) were newly diagnosed with HCV, including 1.8% (13/735) of HIV-positive MSM, 0.7% (3/440) of MSM of unknown HIV status and 0.2% (2/855) of HIV-negative MSM. HCV positivity was significantly associated with HIV status (p<0.001). When compared with HIV-negative MSM, HIV-positive MSM had higher rates of sharing snorting drug equipment, injecting drugs/'slamming' and using recreational drugs (all p<0.05) but lower rates of five or more sexual partners and insertive unprotected anal intercourse (p<0.05). MSM newly diagnosed with HCV had significantly higher prevalence of unprotected sex, sex with someone HCV positive, fisting, group sex, ever injecting drugs/'slamming' and recreational drug use (p<0.002). CONCLUSIONS: In this survey, HIV-positive MSM had significantly different drug use behaviour which may explain the higher HCV burden. However, HCV was also associated with HIV-negative MSM engaging in high-risk sexual practices. All MSM attending sexual health clinics must have a risk assessment and HCV screening should be offered based on the risk. Further studies are warranted to explore the interplay between HCV and HIV risk associated with drug use versus sexual practices.

A case of Bowenoid papulosis of the penis successfully treated with topical imiquimod cream 5%.

Bowenoid papulosis is a pre-malignant condition affecting the ano-genital area. Pathogenesis may be associated with high-risk human papillomavirus genotypes, and sexual transmission is the most likely mode of acquisition. Risk of progression to invasive disease is low. Treatment usually involves locally destructive or ablative therapies. We report well-tolerated, successful clearance of bowenoid papulosis of the penis in a 25-year-old male, using topical Aldara (imiquimod) cream 5%, once every other day for two months.

Managing vulvar lichen sclerosus in U.K. genitourinary medicine clinics.

OBJECTIVE: To survey genitourinary physicians in the United Kingdom on their approaches to the management of vulvar lichen sclerosus. STUDY DESIGN: Questionnaire survey of United Kingdom genitourinary consultants. RESULTS: Seventy-one percent of genitourinary physicians biopsy vulvar lichen sclerosus. For treatment, 78% of clinicians use a high-grade topical corticosteroid, such as 0.05% clobetasol propionate. Topical sex steroids are used by a minority of clinicians. Cases are followed by 80% of respondents. Having made the diagnosis of this condition, 30% of respondents refer the case to either a dermatologist or gynecologist for further management. Fifty-two percent refer only after treatment failure. CONCLUSION: Genitourinary physicians in the United Kingdom see and manage cases of vulvar lichen sclerosus in genitourinary medicine clinics. However, a majority of clinicians refer these cases at some stage. A coordinated and multispecialty approach between genitourinary physicians, dermatologists and gynecologists would provide coherent management of vulvar lichen sclerosus.

Value of screening for oro-pharyngeal Chlamydia trachomatis infection.

AIMS: To determine whether oro-pharyngeal colonisation by Chlamydia trachomatis occurs in patients at risk of genital chlamydia infection; to determine whether screening pharyngeal specimens by polymerase chain reaction (PCR) increases detection of C trachomatis compared with isolation and the immune dot blot test; and to correlate the detection of C trachomatis and Neisseria gonorrhoeae in the pharynx with a history of oro-genital contact. METHODS: Thirteen homosexuals and 11 heterosexuals were included in the study. Urogenital and pharyngeal specimens were tested for C trachomatis and N gonorrhoeae using standard clinical diagnostic procedures. Two different PCR methodologies were also used to detect C trachomatis in the pharyngeal specimens. Results were correlated with the mode of sexual practice. RESULTS: Oro-genital sexual contact was practised by 64.9% (72/111) of heterosexuals in addition to penetrative penovaginal intercourse. Additionally, 62.1% (77/124) of all patients did not use any form of barrier protection. Of those who admitted to oro-genital sexual contact, 17.6% of patients with a genital chlamydial infection and 36.4% of those with genital gonorrhoea also had asymptomatic pharyngeal colonisation. C trachomatis was detected in three of 124 (2.4%) pharyngeal specimens by PCR which were reported as negative by chlamydial culture; one was positive by the immune dot blot test. CONCLUSION: The majority of patients practised unprotected oro-genital contact and significant pharyngeal colonisation by C trachomatis and N gonorrhoeae occurred if genital infection was present. Despite the use of PCR in a population at high risk of sexually transmitted disease, the prevalence of chlamydia in the pharynx was very low. This indicates that transmission of C trachomatis to the oro-pharynx does not pose a serious health risk and that screening of patients for oro-pharyngeal C trachomatis is not worthwhile.

Transrectal ultrasound in male urethritis.

OBJECTIVE: To assess the prevalence of prostatic abnormalities in men with gonococcal and non-gonococcal urethritis using trans-rectal ultrasonic markers. DESIGN: A case control study of patients attending a department of genitourinary medicine with symptoms of urethritis. SETTING: Department of Genitourinary Medicine and Department of Radiology in Manchester Royal Infirmary. RESULTS: A total of 42 patients were recruited to the study: 26 with urethritis and 16 controls. Of the 26 study patients, six were gonococcal, four chlamydial, two mixed gonococcal and chlamydia and nine non specific (no organisms detected). Of the 26 study patients, 16 had abnormal scans (61.5%), eight from the chlamydia group and eight from the non specific group. No abnormalities were found in the gonococcal and mixed group. Of the 16 control patients, five had abnormal scans (31.25%), three of these have had a past history of chlamydial urethritis. CONCLUSION: The prevalence of prostatic abnormalities in patients with non-gonococcal urethritis was significantly higher when compared with controls. The cause of these abnormalities is unclear, but is compatible with inflammatory changes within the gland.

Prevalence of occult human papillomavirus infection, determined by cytology and DNA hybridization, in heterosexual men attending a genitourinary medicine clinic.

One hundred and five heterosexual men without evidence of clinical anogenital warts and attending a genitourinary medicine clinic were studied. Three separate specimens for cytology were taken from (i) the distal urethra including the perimeatal area, (ii) the penile shaft and glans penis including the sub-preputial area, and (iii) from the anorectal area using a proctoscope. Pooled specimens of exfoliated cells from these sites were also taken for the detection of human papillomavirus (HPV) by DNA hybridization. Twenty-eight (27%) of the men had cytological evidence suggestive of HPV infection. HPV genome was detected in 21 (20%) of the men by DNA hybridization and 95% of them were carrying HPV 16 genotype either alone or in combination with other genotypes. A total of 42 (40%) of patients had evidence of occult HPV infection using cytology and/or DNA hybridization techniques collectively. None of the epidemiological risk factors were significantly associated with occult HPV infection in this study. The significance of this high incidence of sexually transmissible HPV genomes, mostly HPV16 in the anogenital area of heterosexual men attending genitourinary medicine clinics requires further study.

Comparison of cotton wool swab and cytobrush for detection of chlamydial infection in women attending a genitourinary medicine clinic.

Endocervical specimens obtained by cytobrush and conventional cotton wool swabs from 90 women attending a genitourinary medicine clinic were compared for their efficiency in detecting chlamydial infection. Isolation of Chlamydia trachomatis and detection of the chlamydial lipopolysaccharide antigen were attempted on each specimen. Antigen was detected in 18% of cytobrush and 17% of swab specimens. The cytobrush proved less suitable than swabs for isolation because 8 cytobrush specimens (9%) were toxic to the McCoy cells. Toxicity was significantly associated with an infected endocervix (2P = 0.004). Cytobrush therefore appeared to have little advantage over the much cheaper alternative, the cotton wool swab.

Avascular necrosis of the hip in a man with HIV infection.

The development of an osteonecrotic (avascular necrosis) hip joint in a patient with symptomatic CDC Stage 1V C2 disease is reported. The diagnosis was aided by radiological assessment and confirmed by radioisotope bone scan. This case serves as yet another musculoskeletal manifestation in association with HIV infection.

Ayre v Aylesbury cervical spatulas.

A single blind crossover study compared the traditional Ayre spatula with the new Aylesbury spatula. The study group consisted of all women attending the department of genitourinary medicine during a 16 month period. The same incidence (3.6%) of dyskaryotic smears was found using the Ayre spatula (74/2077) as the Aylesbury spatula (72/2003). The incidence of smears with endocervical cells, however, was significantly greater using the Aylesbury (33.4%) than the Ayre (20.4%) spatulas, despite there being no difference in the incidence of smears with epithelial abnormalities. Quantitative studies thus showed that the Aylesbury gave no more accurate results than the Ayre spatula.
