During the period 1 January 1990-31 December 1990, 68 neonates with congenital abnormalities were successfully analysed for chromosome abnormalities in order to determine the contribution of chromosome aberrations to the aetiology of congenital abnormalities. The neonates were karyotyped employing the G-banding technique. Twenty-nine babies showed abnormal chromosome karyotypes. Twenty-six were...

* Four cardiovascular abnormalities account for the great majority of reported cases of sudden cardiac death in young athletes: hypertrophic cardiomyopathy (a pathologically enlarged heart), congenital (inherited) abnormalities of the coronary arteries, dissecting aortic aneurysms (bulging of the aorta with blood passing between layers of the arterial wall) in athletes with Marfan syndrome (a c...

In this study the authors attempted to determine the frequency of the classical chromosomal syndromes as a cause of congenital heart disease and sought other cytogenetic abnormalities in patients with congenital heart disease, selected either for the presence of extracardiac abnormalities or the existence of congenital heart disease in other members of the family. Of the 275 patients whose kary...

Teratogens are responsible for a large number of congenital abnormalities. The repercussions ignorance to the agents pregnant person could possibly be exposed can result in irreversible malformation fetus. This paper uses studies done by National Institutes Health (NIH) and Centers Disease Control Prevention (CDC) explore three major teratogenic agents--alcohol, smoking, drugs--and effects they...
