Patient is current breast-fed, so we can eliminate fructose (fructose is found in honey and fruits and some formula, but not in breast milk). Patient has reducing substances but no glucose in the urine, so he must some non-glucose sugar. My differential for reducing non-glucose sugars in the urine is disorders fructose metabolism or galactose metabolism. We have eliminated fructose, so that leaves us with galactokinase deficiency or classic galactosemia.
sympathetikey& Galactokinase deficiency would be much milder.+9
smc213Big was soybean formula not giving any issues. Soy-milk can be used as a substitute formula in patients with Classic Galactosemia since it contains sucrose (->fructose and glucose).+4
oslerweberenuWhy can't this be glucose 6 phosphatase deficiency
Confused me +
almondbreeze@oslerweberenu G6PD - increased RBC susceptibility to oxidant stress (eg, sulfa drugs, antimalarials, infections, fava beans) -> hemolysis; has nothing to do with presence of reducing sugar +1
makinallkindzofgainz@almondbreeze; Glucose-6-phosphatase deficiency is Von Gierke disease, they are not referring to G6PD deficiency (an entirely seperate disease)+9
