Description

Birth defects represent one of the main causes of infant mortality and morbidity around the world, especially in developed countries such as the United States. They occur in approximately 2 to 3 percent of all live births (1). Thus, identification of factors that could reduce the incidence of these conditions is of utmost importance in an attempt to reduce perinatal morbidity and mortality. Although some congenital anomalies have a strong genetic component, in most, the etiology is either unknown or secondary to multiple factors that may affect the developing embryo or may increase its vulnerability to other teratogenic insults. Some teratogens such as drugs and alcohol are well documented, but others may be exerting their harmful effect without knowledge from the mother. Hyperthermia associated to high fever, for example, has been linked to a higher incidence Of congenital anomalies (2). Avoidance of these potentially modifiable risk factors may reduce the incidence of certain congenital anomalies.
