The current practice for treating neonates for jaundice centers on the recommendation that bilirubin levels should be kept below 20 mg/dL. Preventing bilirubin levels from exceeding 20 mg/dL, however, does not guarantee the avoidance of kernicterus, lower IQs or neurologic abnormalities. Studies in the 1960s and 1970s reported cases of ...

Ten pearls (and pitfalls) in the management of the jaundiced newborn: Remember to take a history. Ask about jaundice in previous siblings and check family ethnicity. Don't ignore jaundice in the first 24 hours--it is considered pathologic until proven otherwise. Some normal infants may appear jaundiced and have a bilirubin ...
Blackburn S - - 1995
Jaundice is a common physiologic problem seen in both term and preterm infants. Normal transitional changes in bilirubin metabolism lead to physiological jaundice in many infants. In some infants these normal changes at birth may be exaggerated, such as occurs with immaturity, or may interact with health alterations (pathologic jaundice), ...
Seidman D S - - 1995
Severe neonatal hyperbilirubinemia can occur without apparent reason in term healthy breast-fed infants and some develop kernicterus. The aim of our study was to assess the incidence of severe hyperbilirubinemia in term healthy newborns discharged from the hospital. From January 1 through December 31, 1994, 6705 infants were delivered at ...

Neonatal jaundice is known to be more severe in Taiwanese infants than in Caucasian infants. Although ABO fetomaternal incompatibility and glucose-6-phosphate dehydrogenase deficiency have been shown to play a role in the etiology of neonatal jaundice in some Taiwanese infants, the etiology in the majority of cases is unknown. In ...
Knudsen A - - 1995
Since newborn infants are frequently sent home within 24-48 h after birth, the prediction of severe hyperbilirubinaemia, requiring treatment, is important. We tested the prediction of the need for phototherapy by measuring the yellow skin colour and the progression in yellow skin colour over 6 h using transcutaneous bilirubinometry (TcB), ...

PURPOSE: To evaluate the kinetics of erythropoietin (EPO) production and address the pathogenesis of anemia of prematurity, we measured EPO levels in infants during the first year of life. PATIENTS AND METHODS: Using a radioimmunoassay, serum EPO levels were measured in 97 infants classified into three groups according to weight: ...
Hegyi T - - 1994
We hypothesized that because bilirubin is a potent free-radical quencher, infants without disorders that have oxygen-radical disease (ORD)-mediated mechanisms may have higher bilirubin levels than infants suffering from conditions possibly associated with ORD-mediated mechanisms (e.g., necrotizing enterocolitis, broncopulmonary dysplasia, intraventricular hemorrhage, and retinopathy of prematurity). We identified 25 infants (birth ...
