Text Extraction

Sirenomelia is a fatal condition characterized by the fusion of the lower extremities, single umbilical artery, and severe malformations of the genitourinary and lower gastrointestinal tract. It can occur either as a separate entity or be associated with with caudal regression syndrome. It is usually fatal within a day or two of life due to the complications associated with abnormal development of kidneys and bladder as well as their function. In Mexico, it has an incidence of 1 per 60,000 newborns; it occurs more frequently in monozygotic pregnancies than in singleton pregnancies. The etiology of this anomaly is controversial and complex because in most cases there are neither inheritance patterns nor genetic backgrounds tested. Some authors state that this malformation is associated with maternal diabetes, excessive doses of vitamin A, and exposure to cocaine but nothing is concrete yet.
