Disaccharide Intolerance in Infancy

Abstract
Three cases of disaccharide intolerance in infancy are described; one died at the age of 4 1/2 months. In all three the presenting symptom was intractable vomiting. In two cases lactose, sucrose and galactose were demonstrated in the urine by chromatography, and in the other lactose and galactose. All three showed a gross aminoaciduria. The pathogenesis is discussed and the unreliability as an aid to diagnosis of the standard method for the detection of reducing substances in the urine is stressed.
