This article discusses recent evidence pointing to an infectious etiology of premature rupture of the membranes and preterm labor. We conclude that antepartum infection is strongly related to preterm labor, premature rupture of the membranes and perinatal morbidity and mortality.
This paper describes a serological survey applied to 3098 female commercial sex workers, in order to determine the prevalence of syphilis. The women attend regularly an AIDS orientation center sponsored by CONASIDA in Mexico City. The laboratory tests included the rapid plasma reagin assay (presumptive analysis) and the fluorescent treponemal antibody-absorption technique (confirmatory test). No primary syphilis cases were detected and the prevalence of latent asymptomatic syphilis was 8.2% (255/3098). The sensitivity and specificity of the presumptive test compared to the confirmatory test were 74% and 98% respectively, and the positive predictive value was 77% and the negative predictive value 98%. All seropositive women received the standard penicillin treatment for syphilis. Considerations of importance are offered regarding interpretation and usefulness of this kind of research.
In order to know the prevalence of antibodies to cytomegalovirus in healthy women, we conducted a seroimmunological survey among 1,885 women, ages 13 to 44 years old, living in a suburban area of Cuernavaca City. Overall, 91.6 per cent of women were seropositive and 8.4 per cent seronegative. The prevalence was not significantly different among women of different ages. Nine out of 10 persons already had antibodies at age 14. One out of ten 15-20 years old women represent the maximum risk of primary infection and, at the same time they represent the population with greatest possibilities of getting pregnant. We found a strong relationship of low education, low income, promiscuity, house without public services and early onset of sexual activity with the presence of antibodies to cytomegalovirus. The risk of exposure to primary infection decreases as these epidemiological markers improve.
