Outcome of twin pregnancies according to intrapair birth weight differences.

OBJECTIVE: To assess the clinical significance of twin intrapair birth weight differences. METHODS: This was a retrospective study of twin pregnancy outcomes. Intrapair birth weight differences were stratified into the following six groups: 14% or less, 15-20%, 21-25%, 26-30%, 31-40%, and 41% or more using the larger infant as the growth standard. Statistical analysis was done using the Mantel-Haenzel chi2 test. RESULTS: We studied 1370 consecutive women who delivered at Parkland Hospital, Dallas, Texas, between January 1, 1988, and December 31, 1996, and had twin gestations and live births or fetal deaths within 7 days of delivery. Greater birth weight discordance was significantly associated with preterm delivery due to intervention (P<.001). Noncephalic-cephalic presentations and cesarean delivery were also associated with greater discordance (P = .001 and .02, respectively). Neonatal morbidities, including low birth weight, intensive care admission, and respiratory distress, were all associated with higher birth weight discordance. Fetal abnormalities were more common with increased discordance (P<.001). Greater birth weight discordance was also associated with intrauterine fetal death. There were no differences in outcome for the smaller compared with the larger twin of the twin pair. CONCLUSION: Twin birth weight discordance is problematic because severe divergent fetal growth increases the risk of fetal death and leads to obstetric intervention and consequent neonatal morbidity due to prematurity.

Syphilis.

Syphilis was first recognized as a distinct syndrome in Europe in the fifteenth century. Despite knowledge of congenital infection for more than 450 years and the existence of adequate therapy for 55 years, congenital infection remains a problem for the practicing clinician. Syphilis is caused by Treponema pallidum. Infection may be transmitted horizontally by sexual contact and vertically as a result of hematogenous dissemination across the placenta. Syphilis is classified as primary, secondary, latent, and tertiary. The diagnosis may be established by darkfield examination of clinical lesions and by serological assays. The drug of choice for syphilis is penicillin. This agent is the only antibiotic of proven value for the treatment of congenital syphilis. Accordingly, infected pregnant women who are allergic to beta-lactam antibiotics must be desensitized and then treated with penicillin.

Postpartum endometritis caused by herpes simplex virus.

BACKGROUND: Herpes simplex virus (HSV) is rarely the causative agent of endometritis and is usually found in association with pelvic inflammatory disease. Only one case of postpartum HSV endometritis has been reported. CASES: We describe two cases of herpes simplex postpartum endometritis. Neither patient had genital HSV lesions noted at the time of delivery. The first case developed after a preterm cesarean delivery in an 18-year-old primipara. She had persistent puerperal fever despite broad-spectrum anti-microbial treatment. The second case was a 16-year-old primipara whose vaginal delivery was complicated by severe postpartum endometritis. Vulvar and endometrial cultures were positive for HSV alone in both patients. Both infants died from disseminated HSV infection. CONCLUSION: Herpes simplex virus can cause clinical postpartum endometritis.
