Galactosemia: clinical features, diagnosis and management. A case report.

The case report and discussion presented here were prepared in response to legislation in Louisiana which requires that the Dept of Health and Hospitals establish a program to inform physicians and hospitals of the current medical standards for the diagnosis, clinical management, and recognition of galactosemia. Classical galactosemia is an inborn error of galactose metabolism caused by a deficiency of galactose-1-phosphate uridryl transferase. It is inherited as an autosomal recessive trait and its estimated occurrence is 1/60,000. The presenting symptoms which include vomiting, diarrhea, jaundice, and failure to thrive result from the ingestion of foods containing galactose--breast milk and formulas containing cow's milk. Although some states routinely screen all newborns for galactosemia, the results of the newborn screening are often not available before the infant presents with symptoms. Early recognition and immediate withdrawal of galactose from the diet can prevent serious morbidity and mortality. There is significant clinical variability and not all infants present with typical acute manifestations of the disease.
