BACKGROUND: Hypocalcemia is one of the complications of phototherapy resulted from influence of phototherapy in melatonin secretion reducing corticosterone and ultimately increasing bone uptake. In this study, effect of head covering in prevention of this common and serious complication is studied. MATERIALS AND METHODS: This prospective, randomized clinical trial study conducted on premature infants with gestational age <35 weeks with jaundice. Infants were divided into two groups (n = 43)...

Moderate neonatal jaundice is the most common clinical condition during newborn life. However, a combination of factors may result in acute hyperbilirubinemia, placing infants at risk of developing bilirubin encephalopathy and death by kernicterus. While most risk factors are known, the mechanisms acting to reduce susceptibility to bilirubin neurotoxicity remain unclear. The presence of modifier genes modulating the risk of developing bilirubin-induced brain damage is increasingly being recognised. The Abcb1 and Abcc1 members of the ABC family of transporters have been suggested to have an active role in exporting unconjugated bilirubin from the central nervous system into plasma...

Delayed umbilical cord clamping appears to be beneficial for term and preterm infants. In term infants, delayed umbilical cord clamping increases hemoglobin levels at birth and improves iron stores in the first several months of life, which may have a favorable effect on developmental outcomes. There is a small increase in jaundice that requires phototherapy in this group of infants. Consequently, health care providers adopting delayed umbilical cord clamping in term infants should ensure that mechanisms are in place to monitor for and treat neonatal jaundice...

BACKGROUND: Phototherapy is believed to be a safe method for the management of hyperbilirubinemia. However, there are some controversial issues regarding the genotoxic effects of phototherapy on DNA. The aim of this study was to investigate morphologically both phototherapy-induced DNA double-strand breaks (DSBs) and apoptosis in lymphocytes derived from jaundiced and non-jaundiced neonates. METHODS: Newborns were divided into three groups, including phototherapy-treated (PT, n=30) jaundiced newborns with total serum bilirubin (TSB) levels >15 mg/dl, non-treated jaundiced newborns (C+, n=27), as positive, as well as healthy negative (C-, n=30) controls with TSB levels ranging from 10 and 15 mg/dl and less than 5 mg/dl, respectively...

BACKGROUND: The existing therapeutic methods for neonatal jaundice are costly, time-consuming and potentially risky. Zinc salts can reduce phototherapy duration by precipitating unconjugated bilirubin in the intestine (bilirubin and zinc can form a complex in physiologic pH); however, zinc toxicity is an issue that must be considered since theoretically bilirubin reduction by phototherapy may increase serum zinc levels, making additional zinc supplementation the potential cause of zinc toxicity...

INTRODUCTION: Hemolytic disease of the fetus and newborn (HDFN) is caused by the destruction of fetal red blood cells due to red cell antibodies produced by the mother. HDFN can cause fetal hydrops during pregnancy or neonatal jaundice after birth. Direct Antiglobulin Test (DAT) detects antibodies bound to red cells and is a valuable test aiding in the diagnosis of HDFN. In Iceland DAT is routinely performed on cord blood or newborn blood samples if the mother is Rhesus D negative or has non-A/B red cell alloantibodies...

BACKGROUND: Transcutaneous bilirubin (TcB) is a validated test for systematic screening of neonatal hyperbilirubinemia and monitoring term and near-term infants under phototherapy. OBJECTIVES: To evaluate TcB diagnostic accuracy for very preterm neonates. METHODS: Total serum bilirubin (TSB) and TcB measurements were performed prospectively in a multicenter sample of newborns <30 weeks of gestational age (GA). TcB sensitivity, specificity, predictive values, and likelihood ratios for the detection of neonates requiring phototherapy were calculated over the first 15 days of life, with or without phototherapy, with the expectation of achieving a detection rate of hyperbilirubinemia of over 95%...

BACKGROUND: Transcutaneous bilirubin (TcB) meters are widely used for screening newborns for jaundice, with a total serum bilirubin (TSB) measurement indicated when the TcB value is classified as "positive" by using a decision rule. The goal of our study was to assess the clinical utility of 3 recommended TcB screening decision rules. METHODS: Paired TcB/TSB measurements were collected at 34 newborn nursery sites. At 27 sites (sample 1), newborns were routinely screened with a TcB measurement...

Phototherapy has been used to treat newborns with jaundice for more than 50 years with the presumption that it is safe and effective for all infants. In fact, this presumption may not be true for all infants, especially the smallest and most immature. The safety and efficacy of phototherapy have never really been questioned or adequately tested in the latter, yet clinical applications of phototherapy have been further refined as its mechanisms of action have been better understood and alternative light sources have become available...

OBJECTIVE: This is a comprehensive study designed to evaluate the clinical usefulness of transcutaneous bilirubinometry (TcB) in very low birth weight (VLBW) newborns of African American (AA) descent. METHODS: TcB was conducted at the anterior superior iliac spine (ASIS), temporal region and sternum within 2 h of total serum bilirubin (TSB) measurements in newborns born at ≤32 weeks' gestation prospectively. Average (AVG) TcB levels were also calculated. The relationships between TSB and TcB levels were analyzed using non-parametric Spearman bivariate correlations, a Bland-Altman plot procedure and a decision tree (DT) analysis...

BACKGROUND: Atopic dermatitis (AD) is a chronic inflammatory skin condition with a multifactorial etiopathogenesis. Studies have suggested that several perinatal factors may influence the risk of AD in early childhood. We investigated possible neonatal risk factors such as jaundice, blue light phototherapy, birthweight, gestational age at birth, and season of birth on the risk of developing AD in the first 5 years of life. MATERIALS & METHODS: Data were collected through Danish nationwide administrative registers...

INTRODUCTION: Jaundice is the yellowish pigmentation of the skin, sclera, and mucous membranes resulting from bilirubin deposition. Children born to mothers with HIV are more likely to be born premature, with low birth weight, and to become septic-all risk factors for neonatal jaundice. Further, there has been a change in the prevention of mother-to-child transmission (PMTCT) of HIV guidelines from single-dose nevirapine to a six-week course, all of which theoretically put HIV-exposed newborns at greater risk of developing neonatal jaundice...

BACKGROUND: Infant massage is a natural way for caregivers to improve health, sleep patterns, and reduce colic. We aimed to investigate the effects of infant massage on neonates with jaundice who are also receiving phototherapy. METHODS: Full-term neonates with jaundice, admitted for phototherapy at a regional teaching hospital, were randomly allocated to either a control group or a massage group. The medical information for each neonate, including total feeding amount, body weight, defecation frequency, and bilirubin level, was collected and compared between two groups...

BACKGROUND: Patent ductus arteriosus (PDA) is associated with mortality and morbidity in preterm infants. Phototherapy is a common treatment for jaundice in preterm infants. However, phototherapy has been associated with failure of closure of the ductus arteriosus in preterm infants. OBJECTIVES: To determine if chest shielding of preterm infants receiving phototherapy reduces the incidence of clinically and/or haemodynamically significant PDA and reduces morbidity secondary to PDA...
