title: [Intrauterine infection in relation to the frequence of prematurity and congenital malformations].
abstract: In order to find the relationship between intrauterine infection with frequency of prematurity and of congenital malformations, 1,016 newborns were studied and were divided into four groups: 324 normal babies, 606 prematures, 44 with malformations and 42 infected patients; the latter were confirmed through titration of serum antibodies. The first index of infection was the concentration of IgM greater than or equal to 28 mg. %; thus, the first groups showed evidence of infection in 0.9%; the second in 11%; the third in 40.9% and the fourth, in 100%.
