OBJECTIVE The goal was to develop a predictive nomogram, based on transcutaneous bilirubin (TcB) measurements, for assessment of the risk of significant hyperbilirubinemia in healthy term and near-term neonates. METHODS A total of 10382 TcB measurements were performed with 2039 healthy neonates (gestational age of > or =35 weeks and birth weight of > or =2000 g), with a BiliCheck bilirubinome...

Introduction:Jaundice is considered as a common clinical condition during infancy. Prevention of severe hyperbilirubinemia (jaundice) is safer and easier than current therapies, like phototherapy or blood exchange. In some animal studies, zinc was found effective in reducing jaundice. In this study we evaluated the effect of zinc sulfate on neonatal hyperbilirubinemia. Materials and Methods: Th...

Gunn rats, a mutant strain of rats, suffer from autosomal recessive hyperbilirubinemia. The homozygotes (j/j) develop jaundice soon after birth and often exhibit kernicterus and cerebellar hypoplasia that are due to bilirubin. Therefore, j/j Gunn rats have been used as an animal model of bilirubin encephalopathy, as well as of neonatal hyperbilirubinemia. In this review, we discuss morphologica...

Hyperbilirubinemia is the commonest morbidity in the neonatal period and 5-10% of all newborns require intervention for pathological jaundice. Neonates on exclusive breast-feeding have a different pattern of physiological jaundice as compared to artificially fed babies. Guidelines from American Academy of Pediatrics (AAP) for management of jaundice in a normal term newborn have been included in...

  Background :Severe neonatal hyperbilirubinemia is associated with significant morbidity and mortality. This study was conducted to investigate the causes of severe hyperbilirubinemia leading to Exchange Transfusion (ET) from March 2009 to March 2011 in Bahrami children hospital, Tehran, Iran in order to establish guidelines to prevent profound jaundice & ET.   Methods : 94 neonates underwent ...

Background: Neonatal jaundice is a common problem that can result in serious neurological side effect such as Kern icterus. Several drugs are used to prevent neonatal jaundice. The effect of clofibrate in the prevention of hyperbilirubi-nemia in healthy term neonates has not been paid attention to. This study aimed to evaluate the preventive effect of clofibrate on neonatal jaundice in ter...

In order to screen for neonatal significant hyperbilirubinemia,a propective cross sectional study was carried out on 343 full-term neonates taken to investigator in Kerman between October 1995 and july 1996.there was a linear correlation between serum bilirubin and transcutaneous bilirubinometri (r=0.85,standard error=0.004).sensitivity and specificity of this method were 95% and 84% respective...

Therapies to prevent severe neonatal unconjugated hyperbilirubinemia and kernicterus are phototherapy and, in unresponsive cases, exchange transfusion, which has significant morbidity and mortality risks. Neurotoxicity is caused by the fraction of unconjugated bilirubin not bound to albumin (free bilirubin, Bf). Human serum albumin (HSA) administration was suggested to increase plasma bilirubin...

Severe neonatal hyperbilirubinemia (SNH) and the onset of bilirubin encephalopathy and kernicterus result in part from delayed expression of UDP-glucuronosyltransferase 1A1 (UGT1A1) and the inability to metabolize bilirubin. Although there is a good understanding of the early events after birth that lead to the rapid increase in serum bilirubin, the events that control delayed expression of UGT...

INTRODUCTION Neonatal hyperbilirubinemia is one of the most important factors affecting the auditory system and can cause sensorineural hearing loss. This study investigated the relationship between behavioral hearing thresholds in children with a history of jaundice and the maximum level of bilirubin concentration in the blood. MATERIALS AND METHODS This study was performed on 18 children wi...
