In the 1940s and the 1950s, severe neonatal hyperbilirubinemia and kernicterus were most often encountered with hemolytic disease of newborn (HDN), which occurs most often as a result of the incompatibilities of the Rh and ABO blood groups. With the advent of prenatal testing, maternal Rh°(D) immunoglobulin, phototherapy, and exchange transfusion, the incidence of severe hyperbilirubinemia dras...

Kernicteric pigment was extracted by means of chloroform from the brains of 3 infants. Solutions of it gave a positive diazo reaction, and, as determined electrophotometrically, gave maximum absorption of light having a wavelength of 425 mmicro, being identical in these properties with chloroform solutions of crystalline mesobilirubin. Experimental kernicterus was regularly induced by injecting...

IMPORTANCE Exchange transfusion is recommended for newborns with total serum bilirubin (TSB) levels thought to place them at risk for cerebral palsy (CP). However, the excess risk for CP among these infants is unknown. OBJECTIVE To quantify the risks for CP and CP consistent with kernicterus that are associated with high TSB levels based on the 2004 American Academy of Pediatrics exchange tra...

hyperbilirubinaemia The study by Keren and colleagues is a retrospective study, using infants in whom preand post-discharge TSB has been carried out, hence causing an inherent bias towards the same group. The data for clinical risk have been collected from documents such as admission, intrapartum, and discharge forms. This retrospective collection can result in missing or ambiguous data, as has...

PURPOSE This study aimed to determine the prevalence of glucose-6-phosphate dehydrogenase (G6PD) deficiency among infants with neonatal indirect hyperbilirubinemia (NIH); compare G6PD-deficient and G6PD-normal patients regarding hyperbilirubinemia and need for exchange transfusions (ET); and assess risk factors for ET and kernicterus. METHODS This is a case-control retrospective study. Medica...
