ABSTRACT
The purpose of this study was to calculate the incidence of external birth defects found in 1,650 aborted fetuses studied from September 1978 to February 1983 at the Department of Gynecology and Obstetrics of the University Hospital "Dr. José Eleuterio González" of the U.A.N.L. Medical School. Ninety five of fetuses had external birth defects and 85 had abnormalities in annexes. The Fisher exact test was applied to find the relationship between these abnormalities; no relationship was found. 67.4% had only one birth defect; 32.1% showed several defects. Those defects which were lethal constituted 67%, the majority being of the central nervous system. Defects found in the abdominal wall took second place in frequency followed by abnormalities in either extremity and ear defects. The birth defects seen in early gestational ages differ from those seen in live newborn babies. It is important to carry out morphological and teratological studies, not only in newborns but also during the embrion and fetal periods.

A retrospective study on the incidence and prevalence of congenital malformations in living newborns registered during a period of two years (1987-1988) at the University Hospital "Dr. José Eleuterio González" in Monterrey, Nuevo León was conducted. The data was tabulated based on the classification codes established by the World Health Organization (WHO), grouped according to organs and systems and by sex. Of a total of 9,675 living newborns registered, 224 (2.31%) had a congenital malformation: 102 males, 121 females and one of undetermined sex. The greatest incidence corresponded to the central nervous system, following in descending order the cardiovascular and muscular-skeletal systems, cleft lip and palate, digestive system, genitalia, chromosomic anomalies, respiratory and urinary systems and congenital cataracts. The prevalence of congenital malformations in our population is similar to that reported in other countries with respect to neural tube defects. Muscular-skeletal and multiple malformations were less frequent than seen in other hospitals.
