Congenital Nonobstructive, Nonhemolytic Jaundice

Abstract
SERUM bilirubin concentrations of newborn infants can be reduced by exposure to sunlight or artificial blue light.1 These findings have been confirmed by many investigators in this country and (especially) abroad. More recently, phototherapy has been applied in a prophylactic manner to modify the degree of hyperbilirubinemia in premature infants.2 In the case reported below phototherapy was used successfully to reduce serum bilirubin concentration in an older infant with congenital, nonobstructive, nonhemolytic jaundice unresponsive to phenobarbital therapy.Case ReportR.D.T. (C.H. 477291), an obviously icteric infant with unconjugated hyperbilirubinemia (serum bilirubin as high as 35.4 mg per 100 ml, with . . .
