Patient preferences for partner notification.

OBJECTIVE: To identify patient preferences for notification of sexual contacts when a sexually transmitted infection (STI) is diagnosed. METHODS: A questionnaire survey of 2544 patients attending three large genitourinary clinics at Derby, Birmingham, and Coventry in the United Kingdom. RESULTS: The median age of the respondents was 24 with 1474 (57.9%) women, 1835 (72.1%) white, 1826 (71.8%) single. The most favoured method of partner notification was patient referral, which was rated a "good" method by 65.8% when they had to be contacted because a sexual partner has an STI. Notifying contacts by letter as a method of provider partner notification is more acceptable than phoning, text messaging, or email. Respondents with access to mobile telephones, private emails, and private letters were more likely to rate a method of partner notification using that mode of communication as "good" compared to those without. With provider referral methods of partner notification respondents preferred to receive a letter, email, or text message asking them to contact the clinic rather than a letter, email or text message informing them that they may have an STI. CONCLUSION: Most respondents think that being informed directly by a partner is the best method of being notified of the risk of an STI. Some of the newer methods may not be acceptable to all but a significant minority of respondents prefer these methods of partner notification. The wording of letters, emails, or text messages when used for partner notification has an influence on the acceptability of the method and may influence success of the partner notification method. Services should be flexible enough to utilise the patients' preferred method of partner notification.

New rapid latex agglutination test for diagnosing Trichomonas vaginalis infection.

A newly developed latex agglutination test for Trichomonas vaginalis infection was compared for sensitivity, specificity, efficiency, and positive and negative predictive values with microscopy, culture, and an enzyme linked immunosorbent assay (ELISA) in the diagnosis of 395 women attending a genitourinary medicine clinic. T vaginalis infection was diagnosed in 42 (11%) women. The sensitivities of both the latex agglutination test and the ELISA were 95% compared with 74% for microscopy and 76% for culture. The latex test was specific and showed no cross reaction with a wide range of other genital tract infections. The latex agglutination test can detect antigen in both soluble and insoluble forms, and as it is simple to perform, can be undertaken during routine examination without recourse to special equipment or training. Further evaluation is required.

Prevalence of chlamydial infection in acute epididymo-orchitis.

The prevalence of sexually transmitted infection was studied in 40 men presenting with acute epididymo-orchitis in Leeds. Chlamydia trachomatis infection was identified in 13 of 29 men (45%) aged under 35 years. Neisseria gonorrhoeae was isolated from four of these 13 men with chlamydial urethritis. C trachomatis was isolated from the urethra of only one of 11 men (9%) aged over 35. Appreciable bacteriuria was found in six of these 11 men (55%). Noting details of sexual history and screening for sexually acquired pathogens is advocated in younger men with acute epidiymo-orchitis.

Use of slide latex agglutination test for rapid diagnosis of vaginal candidosis.

A new slide latex agglutination test was compared with microscopy and culture for diagnosing vaginal candidosis in 367 women attending a genitourinary medicine clinic. Vaginal candidosis occurred in 10% of the patients, and 7% had commensal carriage of Candida spp. The slide latex agglutination test was superior to microscopy in immediate diagnosis and was rapid and simple to perform. Of the patients with vaginal candidosis, 72% were detected by slide latex agglutination test compared with 38% by microscopy. The test discriminated well between patients yielding cultures of Candida spp who had symptoms and signs and those who showed commensal carriage.
