Contact tracing for gonorrhoea in homosexual and heterosexual men

We aimed to determine whether the success of partner notification for gonorrhoea in men was affected by sexual orientation.

Analysis of standard clinic and health adviser records of all male patients found to be infected with gonorrhoea between October 1992 and September 1993 were carried out. Of the 278 cases of gonorrhoea in men, 9% (25) were acquired through homosexual intercourse and 91% (253) by heterosexual contact. Fifteen per cent (24) of Caucasians were homosexual but only 0.9% (1) of Afro-Caribbeans were. The mean number of contacts was 1.36 for homosexuals and 1.38 for heterosexuals. Contact information was given by 55% of heterosexuals and 48% of homosexuals. The proportion of acknowledged contacts attending was 38% for homosexuals and 56% for heterosexuals (P=0.054). Fifty-two per cent of homosexuals and 59% of heterosexuals had at least one contact attend. Data analysis on Caucasians only showed Caucasian gay men had a higher mean number of contacts (1.38) than Caucasian heterosexuals (1.28). Caucasian homosexuals had a lower proportion of contacts attending (40% vs 77%) (P=0.05), 54% of homosexual men and 60% of heterosexual men had at least one contact attending (P=0.74).

There is a trend for partner notification to be less successful in homosexual men when all ethnic groups are considered together. In Caucasian men with gonorrhoea, homosexuals have a greater number of partners than heterosexuals and have a lower proportion of total contacts attending but there is no difference in the proportion having at least one contact attending. Data on sexual orientation and ethnicity should be reported in studies assessing efficacy of contact tracing.

Genitourinary medicine: an opportunity to reduce unwanted pregnancy

We sought to investigate contraceptive use in women attending a genitourinary medicine (GUM) clinic, and to assess the need for a contraceptive service in this setting. Female attendees at Nottingham GUM clinic were invited to complete an anonymous questionnaire regarding past and present contraceptive use and whether a contraceptive service within GUM would be utilized. Four hundred and eighty-nine questionnaires were analysed. The majority had previously used condoms (89.8%) or the combined oral contraceptive pill (COCP) (74.6%), and 46.6% and 37.4%, respectively were currently using these methods. Contraception was frequently used for the dual aims of avoiding both pregnancy and infection (48.5%). General practitioners (GPs) and family planning clinics were most frequently cited as sources of regular contraceptive advice, 58.1% and 47.2% respectively, and emergency contraception 50.8% and 37.3%, respectively. If a contraceptive service was available within GUM 56.9% of respondents indicated they would use it.

Is triage an appropriate way of dealing with walk-in patients attending genitourinary medicine clinics?

Genitourinary medicine services have come under severe workload pressure to deal with unprecedented demand over the past five years. Waiting times for patients wishing to access the service have increased significantly. In order to maintain open access for those who require acute attention, many services have introduced triage systems for patients who attend without appointments (walk-ins). We have evaluated a policy of triage for such patients, and the incidence of sentinel sexually transmitted infections (STIs) (gonorrhoea and chlamydia) was determined in those who failed to meet the criteria. Our study has shown a low incidence of STI (1.7%) in those who failed to meet the triage criteria, thus validating the policy.

Standards for comprehensive sexual health services for young people under 25 years

This document is a first response to the need to develop sexual health services for young people on a single site whilst awaiting research from pilot studies of 'one stop shops' suggested in the Sexual Health and HIV strategy. It is a document which is intended to be a tool to use for those wishing to set up a service providing testing for sexually transmitted infections and provision of contraceptive services for those under 25 years. It is not intended that such a service would replace existing specialist or general practice care but complement it, allowing clients to choose the service most appropriate and acceptable to them, with close links and clear pathways of care for referral between services. This paper should be used as a template when initiating and monitoring a clinic but some of the standards may not be achievable without significant financial input. However, economic limitations should not detract from striving to achieve the best possible care for those most at risk from sexually transmitted infections and unwanted pregnancies. For example, not all clinics will be able to provide the recommended tests for the diagnosis for gonorrhoea and chlamydia immediately, but should work towards achieving them. Although the upper age limit in this document is defined as 25 years, some providers may wish to limit clinics to those under 20 depending on local needs. Detailed information on specific issues such as consent and confidentiality, provision of contraception, investigation of non-sexually transmitted vaginal infections and sexually transmitted infection management and diagnosis are referenced and we recommend these are accessed by the users of this document. Many of the references themselves are live documents available on the worldwide web, and are constantly updated. The Sexual Health and HIV Strategy has now been published and these standards are aimed at those who wish to provide a level 2 sexual health service for young people wherever the setting e.g. genitourinary outreach clinic, contraceptive services, general practice. This document is a starting point to be reviewed and updated as new research becomes available, as the Sexual Health Strategy is implemented and with further input from providers of care (family planning, general practice, genitourinary medicine, gynaecology and paediatrics) and service users. All service providers must maintain a high quality of care and have networks both with those who provide more specialized services (Level 3) and Level 1 services. This document is an initial attempt to ensure that there is equity of clinical provision wherever a Level 2 sexual health service is provided and should be a useful tool for those setting up or monitoring services.

The treatment of bacterial vaginosis with a 3 day course of 2% clindamycin cream: results of a multicentre, double blind, placebo controlled trial. B V Investigators Group

OBJECTIVE

To evaluate the efficacy and safety of a 3 day course of intravaginal clindamycin 2% cream for the treatment of bacterial vaginosis.

DESIGN

A prospective, randomised, double-blind placebo controlled study.

SETTING

Departments of genitourinary medicine at Birmingham, Nottingham, Liverpool, Swansea, Leeds, Walsall, Stoke Mandeville, Southampton, Plymouth, Bishop's Stortford and Glasgow.

SUBJECTS

Pre-menopausal women aged 18 years and over, who had symptomatic bacterial vaginosis were randomly allocated to receive either clindamycin 2% cream 5 grams (107 patients) or matching placebo cream (114 patients), daily for three days. Response to therapy was assessed at 7 days (Visit 2) and 28 days (Visit 3).

RESULTS

221 patients with symptomatic bacterial vaginosis were enrolled to the study and of these 141 (63.8%) completed the study. On the "intent-to-treat" (ITT) analysis, 75% of the clindamycin group were classified as "success" or "improved" at visit 2 compared with 13% of the placebo group (p < 0.001). At Visit 3, 41% of the clindamycin group were classified as either "success" or "improved" versus 4% in the placebo group (p < 0.001). Of the 80 patients who were recorded "success" or "improved" at visit 2, 20 (25%) were reported to have a "recurrence" of BV at Visit 3. The meta-analysis on those who were evaluable at Visit 2 and 3 also showed that clindamycin cream 2% was an effective treatment for bacterial vaginosis, and the differences between the clindamycin group and the placebo group were statistically significant.

CONCLUSION

We conclude that a 3 day course of clindamycin 2% cream is an effective, and well tolerated treatment for bacterial vaginosis.

Knowledge of HIV transmission and risk behaviour in Kenyan health care workers

In order to determine knowledge of HIV transmission, sexual risk behaviour and perception of risk in African health care workers, 200 employees at the Aga Khan Hospital, Nairobi, Kenya, were asked to complete an anonymous self-administered questionnaire. There was a 75% response rate. Twenty-five per cent believed that condoms were not protective against HIV transmission. Eighty-nine per cent believed oral sex to be a risk factor, as did 70% for kissing, 41% for masturbation of a partner and 43% for nursing an AIDS patient. Younger people were more likely to think condoms were ineffective (P = 0.007) and that insect bites were a significant risk factor (P = 0.004). Twenty-seven per cent had changed their sexual behaviour as a result of the AIDS epidemic, but 48% did not use condoms with non-regular partners. Four had current or previous homosexual relationships. Seventy per cent believed they were at risk of being HIV positive but only 12% had been tested. We have shown that even in the educated group, misconceptions regarding HIV transmission were high and many continue to be at risk for their sexual behaviour. In addition, in-service training regarding HIV transmission should be considered for health care workers in Africa.

Efficacy of lignocaine analgesia during treatment to the cervix

There is no consensus amongst physicians about the need for analgesia when a woman undergoes ablative therapy of the cervix. Many doctors believe that the discomfort felt during such procedures is insubstantial. By means of a randomised double-blind placebo-controlled trial, we have shown that patients experience considerable pain during cold-coagulation treatment of the cervix. We found that intracervical lignocaine leads to a significant (p < 0.01) reduction in this pain.

Incidence of Ureaplasma urealyticum in endourethral swabs compared with first voided urine from men

The incidence of Ureaplasma urealyticum in endourethral swabs was compared with that in first voided urine specimens from 171 male patients. The organism was isolated from the urethras of 72 (42%) and from the urine of 66 (39%). The interval since last voiding urine did not significantly influence the incidence of infection or ureaplasma counts in either type of specimen. Urethritis was strongly associated with ureaplasma counts of greater than or equal to 5 x 10(5) colour changing units (ccu)/ml in the urethra and greater than or equal to 5 x 10(3) ccu/ml in urine.

Managing trichomonal vaginitis refractory to conventional treatment with metronidazole

Three patients with vulvovaginitis caused by Trichomonas vaginalis, which was refractory to conventional treatment with metronidazole are described. The T vaginalis strain isolated from one patient was resistant to metronidazole (minimum inhibitory concentration (MIC) more than 100 mg/l) under aerobic conditions, although under anaerobic conditions it was as susceptible as a normal reference strain. The effect of the concomitant use of other medication and the influence of other vaginal pathogens on the efficacy of metronidazole are highlighted.

Ciprofloxacin treatment of chlamydial infections of urogenital tracts of women

Ciprofloxacin was evaluated in chlamydial infections of the urogenital tracts of women treated with a dosage regimen of 500 mg orally twice a day for seven days. Of the 40 women evaluated, 30 were infected with Chlamydia trachomatis only, two were infected with Neisseria gonorrhoeae only, and a further eight had combined gonococcal and chlamydial infections. Ten were found to be harbouring Chlamydia trachomatis in the urethra as well as the cervix. Neisseria gonorrhoeae was eradicated from all patients with or without concomitant chlamydial infection. The overall chlamydial reisolation rates were 14% (5/35) four weeks after treatment and 23% (6/26) 11 weeks after treatment. The organism was not reisolated from the urethra of any of the patients after treatment. Ciprofloxacin was effective against Mycoplasma hominis, but almost completely ineffective against Ureaplasma urealyticum.
