Dear Everyone: RAINBOWpeds mentions that the only cases of kernicterus in the past few years were breastfed infants. Is breastfeeding being considered a cause of kernicterus? The only case in the recent literature that I have found was in Pediatrics Vol 93 No. 6 June 1994 pp 1003-1006. He was born via normal vaginal delivery and discharged on day 2 postpartum, healthy and breastfeeding. Came back to the ER on postpartum day 4 with a 1-day history of lethargy, jaundice (bilirubin of 50), decreased appetite, and fever. E. coli was cultured out of his blood on the 4th day of hospital stay (postpartum day 8). I would be interested, in light of all the meta-analysis done by Newman and Maisels, to know what cases is RAINBOWpeds referring? We all know that breastfeeding is not the cause of pathologic jaundice, but rather it is a LACK (shouting) of breastfeeding that creates problems, thanks to deCarvalho and others. Warmly, Nikki Lee
