Infants with mild to moderate hyperbilirubinemia in tropical regions can be treated as safely and effectively with filtered sunlight as with conventional phototherapy, according to a study by US and Nigerian investigators (Slusher TM et al. New Engl J Med. 2015;373:1115-1124).
In countries with limited resources, conventional therapy is often too costly or unavailable because of an inconsistent electrical supply. Thus, newborns with hyperbilirubinemia in these countries may develop acute bilirubin encephalopathy or kernicterus if left untreated.
