Xth International Conference on AIDS and STD in Africa, December 1997 ABSTRACT Objectives: Risk assessment methods has proved to be an insensitive predictors of cervical infections among women presenting with vaginal discharge in the Seychelles. We therefore assessed the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the clinical assessment of cervical status in the same population group. Methods: All consecutive women with STD related complaints attending the only categorical STD clinic in the Seychelles during the period February 1996 – March 1997 were enrolled. Anagraphic and behavioural data were collected by interview. Physical examination with speculum was performed by any of the physicians and nurses working at the STD clinic. The cervical status was categorized as normal, with mucopus, erosion, or bleeding at touch. A diagnosis of cervicitis was based on etiological evidence: N. gonorrhoea was isolated from cervical swabs onto enriches Tayer Martin agar plates; C. trachomatis antigens were detected from cervical swabs using the EIA Sanofi test. Data were computed in Dbase file and analysed with the epiinfo program. Results: 170 women were enrolled, of whom 147 (86%) had either vaginal discharge and/or lower abdominal pain. The mean age was 27 (range 14-48). 133. (78%) had a stable job, 70 (41%) were single, 151 (89%) had sex with a single partner during the previous month. Completed clinical and microbiological information was available for 149.4 (3%), 58 bleeding at clinical assessment. A diagnosis of cervical infection was made in 11 (7%), all infected by Chlamydia trachomatis including one with Gonococcal co-infection. The sensitivity, specification, PPV and NPV of the presence of any one of the above clinical abnormalities of the cervix were 100%, 42%, 12%, 100%. Comments: Clinical examination with speculum insertion is feasible at central and peripheral stations of the public health system in the Seychelles. The presence of cervical abnormalities seems to be a sensitive, though non specific, indicator of cervical infection in our sample of women with low prevalence of STD risk indicators.

Xth International Conference on AIDS and STD in Africa, December 1997 Facts The risk assessement method has proved neither sensitive nor specific in women with vaginal discharge or pelvic pain in the Seychelles. There is low prevalence of STD risk indicators and low prevalence of cervicitis in the population. Xth International Conference on AIDS and STD in Africa, December 1997

Xth International Conference on AIDS and STD in Africa, December 1997 Facts Women presenting with genital discharge or pelvic pain in the Seychelles are much more likely to have vaginal (70%) rather than cervical infections (8%). However, cervical infections determine more severe morbidity and represent a public health problem due to sexual transmission. Xth International Conference on AIDS and STD in Africa, December 1997

Xth International Conference on AIDS and STD in Africa, December 1997 Comments Clinical examination with speculum insertion is feasible at central and peripheral sations of the public health system in the Seychelles. The presence of cervical abnormalities at clinical examination has higher sensitivity than the risk score method and is feasible at central and peripheral health centres in the Seychelles.
