Abstract
Venereal syphilis is highly prevalent among women of childbearing age in Zambia. It is estimated to contribute 25-30% of the perinatal mortality rate of 50 per 1,000 births at the University Teaching Hospital in Lusaka. Because of multisystem involvement, early congenital syphilis, the offshoot of maternal syphilis, has varied criteria for its diagnosis. Therefore, in an attempt to draw guidelines for an easier and more reliable diagnosis, the authors analyzed the clinico-radiologic features of congenital syphilis in 202 patients. Although all infants were under the age of six months, there were several significant differences in the manifestations of the disease among neonates and the postneonates. The younger infants had a higher incidence of jaundice and mortality, whereas joint swelling, skin rash, snuffles, anemia, and periosteal reaction visible in X-rays of long bones were typical findings among the older group. The radiologic changes were seen in > 95% of patients in both groups. About 84% of mothers had attended prenatal clinics, but < 20% of the women had been tested for syphilis. Since early congenital syphilis is common in many parts of the world and since all serologic tests have limitations, awareness of appropriate diagnostic criteria is recommended for all medical personnel.
