Abstract
Hyperbilirubinemia is one of the common and major problems during neonatal period. Our propose was to determine the etiologic and predisposing factor in neonatal hyperbilirubinemia. We analyzed the patients record of 312 neonate including 184 male and 128 female with median age of 16.5 days (range 6-28 days) in children medical center hospital at 1998. The main cause of hyperbilirubinemia in our study was breast feeding (76.6 percent), followed by sepsis (11.5 percent) and hypothyroidism (10.6 percent). Also other uncommon etiology of hyperbilirubinemia that were seen in our patients were TORCH, G6PD deficiency and cephalhematoma. The age of 60 out of our patients (19.2 percent) was 6 days and others were 7 days (15.7 percent), 8 days (14.4 percent) and only 2 out of 312 patients were at age of 28 days. According to our study we suggest that role of breast-feeding should be considered in any neonate with hyperbilirubinemia.

Abstract
Background: Jaundice is a common and benign problem in neonatal period. Several therapeutic procedures for decreasing of serum bilirubin level has been recommended. phototherapy is most common them. Our goal Form this study is the evaluation of serum therapy effects in decreasing of serum bilirubin concentration in icteric infants that are treated with phototherapy.
Methods: This is a prospective clinical trial in Najmeih Hospital in 2002. In this study 80 term icteric infants with bilirubin level greater than 17 mg/dl were randomized in two groups, both groups underwent phototherapy and in the case group intravenous fluid supplementation was added. There were no significant differences in the mean gestational age, birth weight, hemoglobin, and also in total serum bilirubin level at admission in the two groups.
Results: There were no significant differences in the mean rate of of serum bilirubin level decline during first 24 and 48 hours of hospitalization and also the time of bilirubin decreasing to less than 15 mg/dl and the length of hospitalization in two groups.
Conclution: Our study showed intravenous fluid supplementation could be limited to special cases of neonatal icter such as moderate to severe dehydration.

Abstract

Background: Hyperbilirubinemia is the most common cause for readmission in the early neonatal period 5 to 36 percent of healthy term infants who are discharged from hospital are again hospitalized due to severe to moderate hyperbilirubinemia. Detection of major and minor risk factors associated with neonatal jaundice helps to identify high-risk infants and prevent neonatal jaundice. This study was performed aiming to evaluate the major and minor risk factors associated with jaundice in infants hospitalized.

Methods: This cross-sectional study was performed on 2207 term infants (<15 days) with hyperbilirubinemia (>15 mg/dl) in neonatal clinic or emergency unit or neonatal intensive unit, of Mashhad Ghaem Hospital, Iran, from April 2010 to May 2016. The jaundice of infants was confirmed by the pediatrician and laboratory tests. Then the researcher-made questionnaire containing maternal information and neonatal characteristics was completed. Values were expressed as mean±SD. Student t-test and Mann-Whitney test were used as appropriate. P-value less than 0.05 was considered significant.

Results: Sixty one percent of neonates had major risk factors and 80% of neonates had minor risk factor for jaundice. For neonatal jaundice, the most common major risk factors were significant weight loss (27.5%), jaundice visible in the first 24 hours (16.3%), history of treatment with phototherapy and exchange transfusion in sibling (14.8%), Gestational age of 35 to 36 week (9.9%), ABO incompatibility (9.2%), RH incompatibility (3.3%) and G6PD deficiency (3.33%), and the most common minor risk factors were age over 25 years (51.4%), male (49.7%), history of hyperbilirubinemia in sibling (22.3%), diabetic mother's infants (1.5%).

Conclusion: The major risk factors for neonatal hyperbilirubinemia were significant weight loss, jaundice visible in the first 24 hours, history of treatment with phototherapy and exchange transfusion in sibling, gestational age of 35 to 36 week, ABO incompatibility, RH incompatibility and G6PD deficiency.

Volume 76, Issue 10 (1-2019)
Abstract
Background: Phototherapy is the most effective treatment for neonatal jaundice and intermittent phototherapy is as effective as continuous phototherapy but with fewer complications and more benefits. This study compared the hospital length of stay, duration of phototherapy and the reducing rate of total serum bilirubin after 24 and 36 hours of phototherapy in two groups.
Methods: The current double-blinded randomized controlled trial was conducted on 60 icteric term neonates from November 2016 to June 2017. A total of 60 icteric term neonates were randomly divided into two groups. In the continuous group, the phototherapy device was turned on for 24 hours and in the intermittent phototherapy group, the phototherapy device was turned on for 18 hours and off for eight hours. Inclusion criteria were term neonates with non-hemolytic hyperbilirubinemia admitted to the neonatal ward of Loghman Hospital, Tehran, Iran. Infants were excluded for any of the following reasons: Hemolytic anemia, prematurity, sepsis, sever hyperbilirubinemia (total bilirubin>18 mg/dl), direct hyperbilirubinemia and onset of jaundice within the first 24 hours of life. In both arms, phototherapy continued until total serum bilirubin reached<11 mg/dL.
Both early and late complications were compared including the length of hospital stay, duration of phototherapy, the rate of kernicterus, decreasing rate of serum bilirubin after 24 and 36 hours.
Results: The demographic parameters did not differ significantly between the intermittent and continuous phototherapy groups. The length of hospital stay was 2.3±0.60 and 2.46±0.93 days in the continuous and intermittent groups, respectively (P=0.516) and there was not significant differences between them. The duration of phototherapy was 45.26±16.39 and 46±11.82 hours in the continuous and intermittent groups, respectively, and they had no significant differences (P=0.843). The rate of serum bilirubin cessation in the two groups was similar after 36 hours.
Conclusion: According to the current study results, intermittent phototherapy was as effective as continuous phototherapy to treat icteric full-term neonates. The intermittent phototherapy also helps to maintain mother-infant bonding and it is useful to maintain breastfeeding.

Abstract
Background: The effects of magnesium physiology are contradictory to the neurotoxic effect of bilirubin, but the relationship between magnesium level and hyperbilirubinemia in neonates has not been well studied. In this study, we investigated the relationship between serum magnesium level and hyperbilirubinemia and hyperbilirubinemia complications at the Children’s Medical Center.
Methods: In this cross-sectional and prospective study, 100 neonates who were admitted to the Children's Medical Center from October 2018 to 2019 due to neonatal jaundice were enrolled. Neonates were divided into two groups: serum bilirubin levels 16-20 mg/dl were included in the moderate hyperbilirubinemia group and bilirubin >20 mg/dl into severe hyperbilirubinemia group. Serum magnesium levels and clinical complications of hyperbilirubinemia including fever, seizure, apnea, bradycardia, and abnormal neurological examinations were recorded in these infants.
Results: In this study, 100 neonates were evaluated. The mean serum magnesium level in these patients was 2.32 mg/dl. This rate was significantly higher in neonates with seizure (P=0.038), hyperbilirubinemia fever (P=0.048), and neonates with chronic encephalopathy (P=0.003). The mean serum magnesium level was significantly higher in severe hyperbilirubinemia (P<0.001). Serum Magnesium in complications of chronic encephalopathy (P=0.007), Fisting (P=0.001), retrocoli (P=0.001), hypertonia (P=0.004), hypotonia (P=0.001) and seizures (P=0.030) were significantly different. The serum magnesium levels were positively correlated with total bilirubin (r=0.443, P<0.001). The magnesium levels correlated with the chronic encephalopathy (OR: 4.15, P=0.040) and it was observed that magnesium levels above 2.15 could predict chronic encephalopathy with a sensitivity of 100%, the specificity of 47.82%, a negative predictive value of 100% and a positive predictive value of 14.28%.
Conclusion: The results of this study showed that serum magnesium levels significantly correlated with serum total bilirubin and magnesium cutting points above 2.15 mg/dl in patients with jaundice could predict chronic encephalopathy.
