RESUMO
BACKGROUND: Schistosoma (S.) haematobium is a neglected tropical disease which may affect any part of the genital tract in women. Female genital schistosomiasis (FGS) may cause abnormal vaginal discharge, contact bleeding, genital tumours, ectopic pregnancies and increased susceptibility to HIV. Symptoms may mimic those typical of sexually transmitted infections (STIs) and women with genital schistosomiasis may be incorrectly diagnosed. An expert consensus meeting suggested that the following findings by visual inspection should serve as proxy indicators for the diagnosis of schistosomiasis of the lower genital tract in women from S. haematobium endemic areas: sandy patches appearing as (1) single or clustered grains or (2) sandy patches appearing as homogenous, yellow areas, or (3) rubbery papules. In this atlas we aim to provide an overview of the genital mucosal manifestations of schistosomiasis in women. METHODOLOGY/PRINCIPAL FINDINGS: Photocolposcopic images were captured from women, between 1994 and 2012 in four different study sites endemic for S. haematobium in Malawi, Zimbabwe, South Africa and Madagascar. Images and specimens were sampled from sexually active women between 15 and 49 years of age. Colposcopic images of other diseases are included for differential diagnostic purposes. SIGNIFICANCE: This is the first atlas to present the clinical manifestations of schistosomiasis in the lower female genital tract. It will be freely available for online use, downloadable as a presentation and for print. It could be used for training purposes, further research, and in clinical practice.

INTRODUCTION: Human papillomavirus (HPV) prevalence and type distribution were estimated among 90 female sex workers (FSWs) aged 18 to 58 years in Antananarivo, Madagascar. METHODS: A total of 90 FSWs aged 18 to 58 years in Antananarivo, Madagascar, were included in this study. Information on sexual and behavioral characteristics was obtained via a questionnaire. Exfoliated cervical cell specimens were collected for conventional cytologic examination and HPV DNA testing by polymerase chain reaction. The prevalence rates of HPV DNA and their corresponding 95% confidence intervals were stratified into the following 3 age groups: younger than 25, 25 to 34, and 35 years or older. To assess the association between HPV DNA positivity and sociodemographic and sexual behavioral factors, age-adjusted odds ratios and 95% confidence intervals were calculated using unconditional logistic regression. RESULTS: The HPV prevalence in exfoliated cervical cell specimens was 36.7%. The most common HPV types found were HPV-52 (11.1%), HPV-31 and -39 (each at 5.6%), and HPV-16 and -83 (each at 3.3%). The prevalence of low-grade squamous intraepithelial lesions was 3.3%, and that of atypical squamous cells of undetermined significance was 18.9%. No high-grade lesion was found. Although associations were imprecise, the HPV prevalence was higher among women who reported younger age at the first intercourse, contraceptive use, a history of cervical lesions, and no history of condom use. DISCUSSION: The prevalence rates of HPV and cervical lesions among FSWs in Madagascar appear higher than among FSW populations from other African countries with a relatively higher population-based prevalence of human immunodeficiency virus infection.
