ObjectiveTo describe early neurodevelopment outcomes of neonates with severe hyperbilirubinemia without acute bilirubin encephalopathy (ABE).MethodsNeonates born at gestation ≥35 weeks, admitted to NICU with total serum bilirubin (TSB) in exchange range with no features of ABE, were followed up until the age of 6 months. Infants were assessed for impaired hearing and neurodevelopment at 3 months and 6 months of age.ResultsA total of 59 neonates were enrolled in the study. At 3 months of age, 7.6 percent of neonates were found to have hypotonia and motor delay, whereas 42.3 percent had abnormal brainstem evoked response audiometery. At 6 months, 6.4 percent of neonates were found to have persistent neurodevelopmental impairment.ConclusionSevere hyperbilirubinemia is associated with impaired neurodevelopment and hearing even in infants without ABE. Peak TSB level strongly correlates with abnormal outcomes.

Introduction: Jaundice is an important problem during neonatal period. When total serum bilirubin (TSB) level exceeds a critical limit, it crosses the blood brain barrier and results into bilirubin encephalopathy. The main aim of therapy for neonatal hyperbilirubinemia is prevention of bilirubin encephalopathy by phototherapy and/or exchange transfusion. The aims of this study were to evaluate the efficacy of exchange transfusion (ET) and observe the adverse events during and following three days of ET in neonates with hyperbilirubinemia. Materials and Method: Hospital based cross-sectional descriptive study. All neonates admitted to neonatal intensive care unit and /or paediatric wards of a tertiary- care centre between September 2010 to March 2012, requiring ET were enrolled. Results: A total of 139 ETs were performed in 120 neonates. The common causes were ABO incompatibility (30.8%), prematurity (30.8%), idiopathic (27.5%), Rh isoimmunization (6.7%) and cephalhematoma (4.2%). Mean pre- ET total serum bilirubin (TSB) was 24.2 mg% dL. There was 58% reduction in TSB in post ET and 31% net reduction in 6 hr post ET. Term and preterm neonates showed equal percentage of TSB reduction. Respiratory distress (10.8%) and bradycardia (6.7%) were the common adverse events during, and hypocalcemia (98.3%) and thrombocytopenia (34.2%) in 3 days following ET. The sick neonates had significantly higher incidence of thrombocytopenia (p= 0.031), respiratory distress (p=0.009), apnea (p<0.001) and cardiorespiratory arrest (p<0.001). Overall mortality was 4.2%, and non-survivors were mostly low birth weight, born outside the present hospital and had higher incidence of adverse events. Conclusion: Exchange transfusion is an effective intervention in reducing the serum bilirubin level. However, these neonates require monitoring of ionised calcium and thrombocytopenia. Sick neonates had higher incidence of adverse events than healthy and close clinical monitoring is needed to improve the outcome.

Background: Hyperbilirubinemia is common in neonates, with higher prevalence among preterm neonates, which can lead to severe hyperbilirubinemia. Assessment of total serum bilirubin (TSB) and use of a transcutaneous bilirubinometer (TcB) are existing methods to identify and predict hyperbilirubinemia. This study aimed to determine TcB cut-off values during the first day for preterm neonates to predict hyperbilirubinemia at 48 and 72 hours. Methods: A total of 90 neonates born ≤35 weeks were included in the study. They were divided into two groups (Group I: 1000-1500 grams; Group II: 1501-2000 grams). The bilirubin level was measured on the sternum using TcB at the ages of 12, 24, and 72 h. TSB measurements were taken on the third day or if TcB level reached ± 1.24 mg/dL phototherapy threshold and if TcB showed abnormal results (Group I: 5.76-8.24 mg/dL; Group II: 8.76-11.24 mg/dL). Hyperbilirubinemia was defined as TSB ≥7 mg/dL for group I and >10 mg/dL for group II. Results: In total, 38 group I neonates and 48 group II neonates were observed. Almost half of neonates in group I (44.7%) were suffering from hyperbilirubinemia at the age of 48 hours, with 45.8% of group II at the age of 72 hours. To predict hyperbilirubinemia at the age of 48 hours, the best 24-hour-age TcB cut-off values were calculated to be 4.5 mg/dL for group I and 5.8 mg/dL for group II. To predict hyperbilirubinemia at the age of 72 hours, we determined 24-hour-age TcB value of 5.15 mg/dL for group II. Conclusion: TcB values in the early days of life can be used as hyperbilirubinemia predictors on the following days for preterm neonates. Close monitoring should be managed for those with TcB values higher than the calculated cut-off values.

Transcutaneous Bilirubinometry

Background: Hyperbilirubinemia is a common problem in newborn. Most of the cases are benign but severe hyperbilirubinemia can lead to kernicterus and brain damage which is preventable. The gold standard to asses neonatal hyperbilirubinaemia is serum bilirubin measurement. Unfortunately, this procedure is invasive, painful and time consuming. As the consequence of missing severe hyperbilirubinemia is serious, there is a constant search to find out a safe method to detect jaundice. Transcutaneous bilirubinometry offers objective method of assessing degree of jaundice reducing subjectivity of clinical assessment.Objective: To evaluate the relationship between transcutaneous bilirubin (TcB) and total serum bilirubin (TSB) and assess whether transcutaneous bilirubinometry can be used as a valid screening method for detecting jaundice in term and late preterm babies.Method: A prospective cross-sectional study was performed in well baby nursery of United Hospital Limited, Dhaka from January 2013 to December 2013. Healthy term and late pre term newborn of ?35 wk gestation with clinical evidence of jaundice were included in the study. Total serum bilirubin was measured by Dichlorophenyl Diazonin method and transcutaneous bilirubinometer (JM-103) was used to measure transcutaneous bilirubin (TcB) level.Result: A total of 116 paired samples were analyzed and found strong correlation between TcB and TSB (correlation coefficient 0.8, mean difference 0.83, SD± 1.96 and 95% CI 0.6 to 1.06). Post natal age has significant association with TcB (p value 0.01) and TSB (p value 0.031). Requirement of phototherapy in both group were also significant (p value <0.001). TcB value of 11 mg/dl was chosen as cut off point corresponding TSB level 13 mg/dl with sensitivity 90% and specificity 71%. Above this level indicate need for blood sampling to take appropriate therapeutic measure.Conclusion: Transcutaneous billirubinometry is a non-invasive and valid screening tool for assessing jaundice in newborn.Bangladesh J Child Health 2015; VOL 39 (3) :116-122

Background: Appendicitis is the most common acute abdominal condition requiring emergency surgery, with a lifetime risk of 6%. Appendectomy continues to be one of the commonest procedures in general surgery, accounts for approximately 1% of all surgical operation. Despite the increased use of ultrasonography, computed tomography scanning and laparoscopy, the rate of misdiagnosis of appendicitis has remained constant (15.3%). The aim of this study was to whether Serum Bilirubin can be considered as a new laboratory marker to aid in the diagnosis of acute appendicitis and if so, does it have the predictive capacity to warn us about complicated appendicitis.Methods: This was prospective observational study done in Mahatma Gandhi Medical College and Research Institute, Pondicherry between November 2014 and August 2016. About 110 patients of acute appendicitis who had undergone appendicectomy were studied. Data was collected and analyzed critically.Results: Males 66 (60%) outnumbered females 44 (40%) and overall mean age was 26.61±12.37 years. Of the 110 patients, 9% were normal appendix, 59.09% were confirmed as acute appendicitis while 31.81% were diagnosed with complicated appendicitis on biopsy. The Sensitivity and Specificity of serum bilirubin as a marker in predicting Acute appendicitis and complicated appendicitis was 47.6% and 90.9% respectively. Similarly, the Positive predicative value and Negative predicative value for the same was 88.5% and 61.5% respectively with odds ratio 12.4 with significant p value <0.0001.Conclusions: Serum bilirubin is easily available test and cheap and can be estimated from the sample of blood drawn for routine blood investigations. Patients with clinical signs and symptoms of appendicitis and with hyperbilirubinemia should be identified as having a higher probability of complicated appendicitis. Hence, serum bilirubin levels have a predictive potential for the diagnosis of severity of acute appendicitis and need for early appendicectomy. If total serum bilirubin is added to already existing laboratory tests, then the diagnosis of complicated appendicitis in clinically suspected cases can be made with fair degree of accuracy, the need for CECT and MRI can be reduced and unnecessary delay in appendicectomy can be avoided.

Background: Timely detection and treatment of pathological hyperbilirubinemia in newbornscan prevent acute bilirubin encephalopathy and its consequences. We aimed to identifyitsoccurrence, presentationtime, phototherapyduration, need for exchange transfusion,and outcome. Methods: In this cross-sectional study, we enrolled all the babies admitted for pathological neonatal hyperbilirubinemia in the university hospital ofBPKIHSin a one-yearduration. Babies with life-threatening congenital malformations or conjugated bilirubin >20% of total serum bilirubin or >2 mg/dl were excluded. Obstetric profile of mothers, clinical and laboratory parameters of babies, onset time of pathological jaundice, duration of phototherapy, need for exchange transfusion or intravenous immunoglobulin were recorded. Neonatal outcome was classified as good and poor and its association with potential predictors analyzed.  Results: One-hundred and fifty babiesdeveloped neonatal jaundice requiring treatment. The most common causes includedABO and Rh setting. No cause was found in 26 (18%) babies. One-hundred and eight babies (72%) were only managed withphototherapy whereas 42 (28%) required both phototherapy and double volume exchange therapy. The majority (84.5%) had good outcome without any residual neurological deficit at discharge.Babies with total serum bilirubin >20 mg/dl at presentation, duration of phototherapy >44.8 h, ABO setting, hemolysis, and out born statussignificantly developed poor outcome (p < 0.05). Conclusion: About 15% of the babies with hyperbilirubinemia had acute bilirubin encephalopathy at discharge suggestive of poor outcome. Babies with high bilirubin at presentation, longer duration of phototherapy, ABO settings, hemolysis, and out born statusdeveloped poor outcome.

Objective. To determine whether transcutaneous bilirubin measurements (TcB) before and during phototherapy taken from covered skin during phototherapy correlate with total serum bilirubin (TSB) levels.Study Design. In this prospective observational study, healthy term newborns who required TSB measurements were included. TcB measurements were taken from the forehead before starting and during phototherapy using the BiliChek device. Before starting phototherapy, part of the forehead was covered. Blood for TSB measurement was collected within 5 minutes of TcB measurements. Correlations and mean differences between TcB and TSB before and during phototherapy were calculated.Result. Paired TSB and TcB measurements before and during phototherapy in 151 newborns were performed. The mean gestational age was 38.8 weeks and birth weight was 3.1 kg; 53% were male. Before starting phototherapy, TSB and TcB were183.8±41.6and 190.5 ± 43 μmol/l, respectively. During phototherapy, TSB and TcB were191.8±39.4and187.8±45.3 μmol/l, respectively. Linear regression analysis showed a significant correlation between TcB and TSB before starting phototherapy and during phototherapy (r: 0.85;p<0.001andr: 80.0;p<0.001), respectively. Before starting phototherapy, the mean difference between TSB and TcB was6.2±23.2 μmol/l, with a 95% CI of −39.3 to 51.7 μmol. During phototherapy, the mean difference was −2.8±23.5 μmol/l, with a 95% CI of −48.9 to 43.3 μmol/l.Conclusion. TcB measurements from covered skin in jaundiced term infants during phototherapy correlate with TSB and can be used to monitor bilirubin levels during phototherapy.

Abstract Background The risk of kernicterus and BIND may be in part determined by total serum bilirubin (TSB) and by the level of non-albumin bound free bilirubin, which can easily pass the blood–brain barrier. Free bilirubin (Bf) seems a more reliable predictor for bilirubin neurotoxicity. Bilirubin/albumin ratio (B/A) is considered a surrogate parameter for Bf and has been more useful than TSB. The aim of the study is to determine whether B/A ratio correlates with BIND in newborns with severe hyperbilirubinemia and if it can predict poor neurologic outcome at 3 months follow up. Results This prospective study included one hundred seventeen outborn neonates ≥ 35 weeks admitted in a tertiary care neonatal intensive care unit, between May and December 2012, with TSB ≥ 20 mg/dl or necessitating exchange transfusion. Total serum bilirubin and serum albumin were done on admission and bilirubin/albumin ratio was calculated. BIND score was calculated. At the age of 3 months, 112 neonates were followed up with a detailed neurological assessment. Babies who depicted any abnormal motor examination were subjected to brain stem auditory evoked response and MRI examination. Seven infants (6.2%) presented with kernicterus on follow up. BIND scores on admission, mean TSB, and bilirubin/albumin ratio was significantly higher in kernicteric infants compared with those having normal neurological outcome at 3 months of age (P 0.001). The lowest TSB level at which kernicterus occurred in our study was 31 mg/dl. Receiver operation characteristics analysis identified B/A ratio cut off value for predicting kernicterus of 9.6 with sensitivity of 100% and specificity of 91.4%, whereas TSB cut off value of 30 mg/dl showed sensitivity of 100% and specificity of 83%. Conclusion B/A ratio is a strong indicator for the risk of kernicterus. B/A is more specific than TSB and should be used in the early management of neonatal hyperbilirubinemia.

Almost half of the neonates in Group I (45%) suffered from hyperbilirubinemia at the age of 48 hours, along with 46% of Group II at 72 hours. The best 24-hour-old TcB cut-off values to predict hyperbilirubinemia at 48 hours were calculated to be 4.5 mg/dL for Group I and 5.8 mg/dL for Group II. The determined 24-hour-old TcB value to predict hyperbilirubinemia at 72 hours was 5.15 mg/dL for Group II. Conclusion: TcB values in the early days of life can be used as hyperbilirubinemia predictors on the following days for preterm neonates. Close monitoring should be managed for those with TcB values higher than the calculated cut-off values.
