Objectives: Polymorphisms of the uridine-diphospho-glucuronosyltransferase 1A1 () gene, hepatic solute carrier organic anion transporter 1B1/B3 () gene, and glutathione S-transferase () gene have been associated with significant hyperbilirubinemia in some populations. This study aims to determine whether the variation of , and genes play an important role in neonatal hyperbilirubinemia in Turkish newborn infants.

Methods: The study included 61 idiopathic hyperbilirubinemia cases, 28 prolonged jaundice cases, and 41 controls.

Objective: This study aims to examine the accuracy of transcutaneous bilirubin (TcB) in estimating the total serum bilirubin (TSB) level at five different sites before and immediately after phototherapy.

Methods: This study prospectively enrolled infants with a gestational age of 34 to 41 weeks who were clinically diagnosed with neonatal jaundice and required phototherapy within 28 days after birth. TcB levels were measured on the uncovered four areas (forehead, mid-sternum, abdomen, and interscapular site) and covered hipbone by using the Dräger JM-103 Jaundice Meter before phototherapy and at 0 min after discontinuing phototherapy.

Townes-Brocks syndrome (TBS) is a rare syndrome characterized by triad of anal, ear, and thumb anomalies. Further malformations/anomalies include congenital heart diseases, foot malformations, sensorineural and/or conductive hearing impairment, genitourinary malformations, and anomalies of eye and nervous system. Definitive diagnosis for TBS is confirmed by molecular analysis for mutations in the gene.

Objective: The perfusion index (PI) is a noninvasive marker derived from photoelectric plethysmographic signals in pulse oximetry in the evaluation of peripheral perfusion. This study was aimed to determine the correlation between PI and left ventricular output (LVO) in healthy late preterm infants at 48 hour of life.

Study Design: With new generation pulse oximeter (MASIMO Rad 7 Oximeter) pre- and post-ductal PI values were recorded from healthy late preterm babies at the 48 hour of life.

Permanent junctional reciprocating tachycardia (PJRT) is most often observed in infants and children and can lead to incessant tachycardia. PJRT is usually refractory to medical treatment. Tachycardia may infrequently occur in the fetus in which case fetal tachycardia transplacental treatment should be started immediately.

Objective: To investigate the early neonatal outcomes of very-low-birth-weight (VLBW) infants discharged home from neonatal intensive care units (NICUs) in Turkey.

Material And Methods: A prospective cohort study was performed between April 1, 2016 and April 30, 2017. The study included VLBW infants admitted to level III NICUs.

Background: To investigate the feasibility of critical congenital heart disease (CCHD) screening test by pulse oximetry in four geographical regions of Turkey with different altitudes, before implementation of a nationwide screening program.

Methods: It was a prospective multi-centre study performed in four centres, between December, 2015 and May, 2017. Pre- and post-ductal oxygen saturations and perfusion indices (PI) were measured using Masimo Radical-7 at early postnatal days.

Hypocalcemia is a rare condition that causes dilated cardiomyopathy and can result in heart failure. Patients with hypocalcemia have been reported to recover in 3 to 12 months after calcium and vitamin D replacement therapy as well as treatment of heart failure. A 6-month-old male patient who presented with dyspnea was admitted to the intensive care unit with severe heart failure and dilated cardiomyopathy.

Objective: The aim of present study was to evaluate the indications and the complications associated with neonatal exchange transfusion (ET) performed for hyperbilirubinemia.

Methods: This study included overall 306 neonates who underwent ET between 2005 and 2012. The demographic characteristics of patients, causes of jaundice and adverse events occurred during or within 1 week after ET were recorded from their medical files.

Introduction: Respiratory syncytial virus (RSV) is a major cause of pneumonia in infants worldwide. We aimed to evaluate the clinical course of community-acquired RSV pneumonia in newborns hospitalized in neonatal intensive care unit.

Materials And Methods: All the newborns diagnosed as pneumonia were prospectively evaluated for RSV infection between November 2010 and April 2011.

We aimed to determine reference values of perfusion index (PI) in healthy newborns during the early neonatal period. Preductal (right hand) and postductal (foot) PI values were assessed during the first 5 days of life by using a new generation pulse oximetry. A total of 241 newborn infants (196 [81.

Background: The aim of this study was to evaluate the features and outcome of classic galactosemia diagnosed in the neonatal period.

Methods: A retrospective study was carried out on 22 newborns with classic galactosemia who were followed-up in a tertiary neonatal intensive care unit from January 2005 to January 2011.

Results: During the study period, 22 (18 boys, 4 girls) newborns were diagnosed with classic galactosemia.

Background: Congenital anomalies are one of the important reasons of mortality and morbidity in newborns. The aim of this study is to determine the incidence, distribution and the mortality of the congenital anomalies in a single neonatal intensive care unit (NICU) from Turkey.

Method: A retrospective analysis was performed between 2005 and 2012 in NICU using a computerized database.
