NUCLEAR ICTERICIA Nuclear jaundice is a little scientifically known pathology, which occurs in newborns and consists of the accumulation of bilirubin in the blood when red blood cells are degraded, because of a deficiency of liver function. It originates from the fourth day and is very serious, because bilirubin accumulates in the brain producing brain damage. It has been determined that high doses of vitamin K, normally administered to reduce the chances of bleeding, produce dangerous levels of bilirubin, and that 1 or 2 mg are sufficient to obtain good results and avoid this risk. Jaundice is visualized by the yellowish color of ka skin (produced by bilirubin) especially in the stomach area and in the white of the eyes. See jaundice
