A randomized controlled trial of laser treatment among hirsute women with polycystic ovary syndrome.

BACKGROUND: Facial hirsutism is one of the characteristic features of polycystic ovary syndrome (PCOS), and this can lead to high levels of depression and anxiety. OBJECTIVES: To evaluate the impact of laser treatment on the severity of facial hirsutism and on psychological morbidity in women with PCOS. METHODS: A randomized controlled trial of five high-fluence treatments (intervention) vs. five low-fluence treatments (control) was performed over 6 months in a National Health Service teaching hospital. Subjects were 88 women with facial hirsutism due to PCOS recruited from hospital outpatient clinics and a patient support group in 2001-2002. The main outcomes were self-reported severity of facial hair (measured on a scale of 1-10), depression, anxiety (measured on the Hospital Anxiety and Depression Scale) and quality of life (measured on the WHOQOL-BREF). RESULTS: Self-reported severity of facial hair in the intervention group (n = 51) fell from 7.3 to 3.6 over the 6-month study period; for the control group (n = 37) the corresponding scores were 7.1 and 6.1. The change was significantly greater in the intervention group [ancova F((1,83)) = 24.5, P < 0.05]. Self-reported time spent on hair removal declined from 112 to 21 min per week in the intervention group and from 92 to 56 min in the control group [F((1,80)) = 10.2, P </= 0.05]. Mean depression scores fell from 6.7 to 3.6 in the intervention group, compared with 6.1 to 5.4 in the control group [F((1,83)) = 14.7, P < 0.05]. A similar change was seen for mean anxiety scores: intervention 11.1 to 8.2, control 9.6 to 9.3 [F((1,84)) = 17.8, P < 0.05]. Psychological quality of life also improved more in the intervention group, from 49.6 to 61.2 vs. 50.1 to 51.5 in the control group [F((1,84)) = 10.9, P < 0.05]. CONCLUSIONS: Laser treatment appeared to reduce the severity of facial hair and time spent on hair removal as well as alleviating depression and anxiety in women with PCOS. These findings suggest that ways of making this method of hair removal more widely available to women with facial hirsutism should be considered.

Epidemiology of HIV among black and minority ethnic men who have sex with men in England and Wales.

OBJECTIVES: To examine the epidemiology of HIV among black and minority ethnic (BME) men who have sex with men (MSM) in England and Wales (E&W). METHODS: Ethnicity data from two national HIV/AIDS surveillance systems were reviewed (1997-2002 inclusive), providing information on new HIV diagnoses and those accessing NHS HIV treatment and care services. In addition, undiagnosed HIV prevalence among MSM attending 14 genitourinary medicine (GUM) clinics participating in the Unlinked Anonymous Prevalence Monitoring Programme and having routine syphilis serology was examined by world region of birth. RESULTS: Between 1997 and 2002, 1040 BME MSM were newly diagnosed with HIV in E&W, representing 12% of all new diagnoses reported among MSM. Of the 1040 BME MSM, 27% were black Caribbean, 12% black African, 10% black other, 8% Indian/Pakistani/Bangladeshi, and 44% other/mixed. Where reported (n = 395), 58% of BME MSM were probably infected in the United Kingdom. An estimated 7.4% (approximate 95% CI: 4.4% to 12.5%) of BME MSM aged 16-44 in E&W were living with diagnosed HIV in 2002 compared with 3.2% (approximate 95% CI: 2.6% to 3.9%) of white MSM (p<0.001). Of Caribbean born MSM attending GUM clinics between 1997 and 2002, the proportion with undiagnosed HIV infection was 15.8% (95% CI: 11.7% to 20.8%), while among MSM born in other regions it remained below 6.0%. CONCLUSIONS: Between 1997-2002, BME MSM accounted for just over one in 10 new HIV diagnoses among MSM in E & W; more than half probably acquired their infection in the United Kingdom. In 2002, the proportion of BME MSM living with diagnosed HIV in E&W was significantly higher than white MSM. Undiagnosed HIV prevalence in Caribbean born MSM was high. These data confirm the need to remain alert to the sexual health needs and evolving epidemiology of HIV among BME MSM in E&W.

Men who have sex with men who are born abroad and diagnosed with HIV in England and Wales: an epidemiological perspective.

Relatively little is known about the sexual health needs of men who have sex with men (MSM) born abroad who reside in the UK. We describe here the epidemiology of HIV among MSM born outside the UK and diagnosed with HIV in England and Wales. Reports of HIV diagnoses in England and Wales received at the Health Protection Agency Centre for Infections were analysed. Between 2000 and 2003, 6386 MSM were diagnosed with HIV in England and Wales. Country of birth was recorded for 3571 (56%). Of those with country of birth reported, 2598 (73%) were born in the UK and 973 (27%) abroad. Of those born abroad (973), 424 (44%) were born in Europe, 141 (15%) in Africa, 104 (11%) in South/Central America and the remainder in other regions. Where reported (949), 69% of MSM born abroad were White, 12% other/mixed, 9% Black Caribbean and 7% Black African. Probable country of infection was reported for 612 MSM born abroad: 52% were infected in the UK, 43% in their region of birth and 5% in another region. Men born abroad represent a significant proportion of HIV diagnoses among MSM in England and Wales. More than half probably acquired their HIV infection in the UK, strengthening the call for targeted HIV prevention and sexual health promotion among MSM who are not born in England and Wales.

Recruiting London gay men into an HIV vaccine trial: is it feasible?

This paper describes a study among HIV-negative gay men in London to examine willingness to volunteer for an HIV vaccine trial. HIV-negative gay men (n=506) were surveyed in central London gyms in February-March 2002. Information was collected on willingness to volunteer for an HIV vaccine trial, attitudes toward HIV vaccines and sexual risk behaviour. Men reporting unprotected anal intercourse (UAI) in the previous three months with a man of unknown or discordant HIV status were classified as being at high risk of exposure to HIV (n=94, 18.6%). The remainder, who reported no UAI or UAI only with another HIV-negative man, were considered to be at low risk (n=412, 81.4%). Just under a quarter of the HIV-negative men in the study (23.4%) said they were either quite likely or very likely to volunteer for an HIV vaccine trial. High-risk men were more likely to say they would volunteer for a trial than low-risk men (37.2% versus 20.2%, p<0.001). Of the 506 HIV-negative men surveyed, eight (1.6%) were both high risk and very likely to volunteer for an HIV vaccine trial, while a further 27 (5.3%) were both high risk and quite likely to volunteer. Based on these figures, we estimated that to recruit 1,000 high-risk HIV-negative men into a vaccine trial between 15,000 and 62,000 HIV-negative men would need to be approached in the community. Compared with those at low risk, a greater proportion of high-risk men said that if they were in an HIV vaccine trial they would be more likely to have unprotected sex (23.4% versus 7.8%, p<0.001); that an effective vaccine will make safe sex less important (45.7% versus 31.3%, p=0.01); and that they would participate in an HIV vaccine trial even if they thought the vaccine might not work (46.8% versus 29.9%, p<0.01). This study suggests that, in London, to recruit high-risk HIV-negative gay men for an HIV vaccine trial many thousands of gay men may need to be approached in the community. Some HIV-negative men said that they would be more likely to have unprotected sex if they took part in a trial.

Popular opinion leaders in London: a response to Kelly.

Controlled trials conducted in the USA provide clear evidence that peer education can bring about a reduction in high risk sexual behaviour among gay men. HIV prevention interventions that systematically identified, recruited, trained and engaged popular opinion leaders (POLs) made a significant impact on sexual behaviour at a community level in small US towns. However, recent trials conducted in the UK have failed to replicate these findings. A POL intervention in London made no significant impact at a community level on the risk behaviours of gay men. Jeffrey Kelly, one of the authors of the US studies, has identified nine core elements central to the popular opinion leader model. In Kelly's view 'the UK projects were not tests of the popular opinion leader model because they did not employ most of these POL core elements'. The absence of any significant impact of the UK programmes on sexual risk behaviour at a community level was not, therefore, surprising. In fact, the London POL project incorporated all the core elements into its design and succeeded in employing seven out of nine in its delivery. Attempts to employ all the core elements, however, were hampered by problems in recruiting popular opinion leaders as well as barriers to communication. Process evaluation revealed that it was these obstacles which limited diffusion. This in turn explained the absence of any impact of the London POL project on sexual risk behaviour at a community level. The obstacles to successful diffusion in London have provided a valuable opportunity for examining the processes that underlie the POL model. Our study raises the question as to whether social interventions shown to be effective in one setting, place or moment in time can be replicated in another.

Use of gay Internet sites and views about online health promotion among men who have sex with men.

In May-June 2002, 4,974 men who have sex with men (MSM), average age 31 years, completed a self-administered questionnaire online accessed through two popular gay Internet sites in the UK (gaydar and gay.com UK). Most men were white (95%), employed (83%), lived in the UK (91%) and self-identified as gay (85%). Nearly half (46%) had not been tested for HIV, while 6% said they were HIV-positive. One-third (31%) reported high-risk sexual behaviour in the previous three months, i.e. unprotected anal intercourse with a partner of unknown or discordant HIV status. Nearly all the men (82%) had looked for a sexual partner on the Internet and three-quarters had been doing so for more than a year. Almost half the men (47%) said they preferred to meet men through the Internet rather than in bars or other 'offline' venues. Although nearly 40% of men said the most important reason for using these Internet sites was to find sexual partners, a further 17% said they primarily used them to have contact with other men, 16% because they were bored, 12% for entertainment, 4% because they were lonely and 3% because they were addicted to it. The majority of men in this survey had favourable attitudes towards online health promotion. Most men thought that Internet sites should allow health workers into chat-rooms (75%); would click on a banner to find out about sexual health (78%); and said if they met a health worker in a chat-room they would find out what they had to say (84%). In multivariate analysis, being HIV-positive, older age and high-risk sexual behaviour were all independently associated with an increased frequency of using the Internet to look for sex (p<0.05). The Internet has emerged as an important meeting place for men who have sex with men. As online HIV prevention initiatives are developed it will be important to monitor the extent to which the favourable attitudes seen here are reflected in preventive behaviours.

Reflecting on the experience of interviewing online: perspectives from the Internet and HIV study in London.

This paper considers some of the strengths and weaknesses of conducting synchronous online interviews for qualitative research. It is based on a study among gay/bisexual men that used both qualitative and quantitative methods to explore the association between seeking sex through the Internet and HIV transmission risk. Between June 2002 and January 2004, 128 gay/bisexual men living in London were interviewed one-to-one by the first author (MD) about their experience of using the Internet to find sexual partners and negotiating condom use for anal sex. Thirty-five men were interviewed online, while 93 were interviewed face-to-face (i.e. offline). This paper draws on MD's experience of conducting these interviews--both online and face-to-face. Synchronous online interviews have the advantage of being cheap, convenient and attractive to people who do not like face-to-face interviews. However, some of the social conventions and technical limitations of computer-mediated-communication can introduce ambiguity into the online dialogue. To minimize this ambiguity, both interviewer and interviewee have to edit their online interaction. One of the distinctive features of the online interview is that it emerges as a form of textual performance. This raises fundamental questions about the suitability of the synchronous online interview for exploring sensitive topics such as risky sexual behaviour.

Trends in sexual behaviour among London homosexual men 1998-2003: implications for HIV prevention and sexual health promotion.

OBJECTIVES: To examine changes in sexual behaviour among London homosexual men between 1998 and 2003 by type and HIV status of partner. METHODS: Homosexual men (n=4264) using London gyms were surveyed annually between 1998 and 2003 (range 498-834 per year). Information was collected on HIV status, unprotected anal intercourse (UAI) in the previous 3 months, and type of partner for UAI. High risk sexual behaviour was defined as UAI with a partner of unknown or discordant HIV status. RESULTS: Between 1998 and 2003, the percentage of men reporting high risk sexual behaviour with a casual partner increased from 6.7% to 16.1% (adjusted odds ratio (AOR) 1.36 per year, 95% confidence interval (CI) 1.26 to 1.46, p <0.001). There was no significant change in the percentage of men reporting high risk sexual behaviour with a main partner alone (7.8%, 5.6%, p=0.7). These patterns were seen for HIV positive, negative and never tested men alike regardless of age. The percentage of HIV positive men reporting UAI with a casual partner who was also HIV positive increased from 6.8% to 10.3% (AOR 1.27, 95% CI 1.01 to 1.58, p <0.05). CONCLUSION: The increase in high risk sexual behaviour among London homosexual men between 1998 and 2003 was seen only with casual and not with main partners. STI/HIV prevention campaigns among London homosexual men should target high risk practices with casual partners since these appear to account entirely for the recent increase in high risk behaviour.

Peer-led HIV prevention among gay men in London: process evaluation.

A peer-led HIV prevention initiative, based on a diffusion of innovation model, was developed for gay men attending gyms in central London. Peer educators were recruited from people who used the gym regularly according to standard selection criteria. After initial training, peer educators agreed to talk to gay men at their gym about HIV prevention, focusing on sexual risk and steroid injecting behaviour. Outcome evaluation revealed that the peer education programme had no significant impact on the risk behaviours of gay men using the gyms. Process evaluation, based on interviews with peer educators, the health promotion team and gym managers threw light on this finding. While it was feasible to set up a peer education programme among gay men in central London gyms, attrition was an important factor. Only one in five potential peer educators initially identified remained with the project throughout, thus limiting the potential for diffusion. Those who did work as peer educators reported barriers to communication within the gyms further limiting the extent to which diffusion occurred. In fact, it appears that the critical mass required for diffusion was never established. This could explain why the intervention had no significant impact on gay men's risk behaviours. A person-time analysis demonstrated that the peer education programme required a substantial input from the health promotion team, equivalent to one team member devoting 2.5 days a week to recruit, train and support peer educators over 18 months. Peer education should not, therefore, be viewed as a low-cost approach to prevention. Many of the insights gained through this process evaluation can inform others planning peer education programmes in other settings.

Seeking sex on the Internet and sexual risk behaviour among gay men using London gyms.

OBJECTIVE: To examine the association between seeking sex on the Internet and sexual risk behaviour among gay men in London. METHODS: In January-February 2000, gay men in London gyms were asked to complete self-administered questionnaires concerning use of the Internet, history of sexually transmitted diseases (STD) and recent unprotected anal intercourse (UAI). Internet sex seekers were compared with other men, also with Internet access, who did not seek sex in this way. RESULTS: Of 743 gay men included in the analysis (121 HIV-positive, 465 HIV-negative, 157 never-tested), 80.9% (601) had access to the Internet. Among those who had access, 34.4% (207) had used the Internet to find a sexual partner; this did not vary significantly by HIV status (P = 0.3). Internet sex seekers were more likely to have had an STD (HIV-negative men, 26.9 versus 17.5%, P = 0.04) or gonorrhoea (HIV-positive men, 22.2 versus 5.8%, P = 0.04) in the previous year than other men with Internet access. HIV-negative Internet sex seekers were also more likely to report non-concordant UAI in the previous 3 months [23.1 versus 11.8%; adjusted odds ratio (aOR), 1.9; 95% confidence interval (CI), 1.2--3.5; P = 0.01]. HIV-positive Internet sex seekers were more likely to report UAI with another positive man (37.8 versus 7.4%; aOR, 7.9; 95% CI, 1.8--34.6; P = 0.006). CONCLUSION: Seeking sex on the Internet was associated with recent STD and high-risk sexual behaviour among HIV-positive and -negative gay men in London. The contribution of seeking sex on the Internet to the recent increase in high-risk behaviour among London gay men merits further investigation.

Acute hospital admissions from nursing homes: some may be avoidable.

A retrospective survey of acute hospital admissions from nursing homes over a year to a district hospital revealed high overall hospital admission rates and wide variations of admission rates from similar homes. Medical admissions dominated, infections and poorly controlled heart failure being notably common. A significant proportion of admissions may have been avoided by active chronic disease management, together with better information for doctors responding to emergency calls and specialist support programmes facilitating in situ treatment.
