Background: This study aims to evaluate the experience of a tertiary health center on the timeliness of postnatal management in newborns with open neural tube defects (NTDs).

Methods: This is a retrospective review of 38 neonates with NTDs who were treated surgically at a tertiary health care center between January 2009 and January 2019. Five neonates with genetic syndromes were excluded.

Aim: For the small for gestational age (SGA) infants born at the normal birth time but whose birth weights were below the 10th percentile and for the appropriate for gestational age (AGA) infants born in normal birth weights according to gestational week, the diameters of right and left coronary arteries were echocardiographically measured in three separate time intervals with their body weights, heights and body surface area parameters. The aim of this study is to compare the progression of coronary artery diameters of SGA infants with AGA infants over time and the effects of coronary artery diameters on the clinical and hemodynamic parameters of SGA babies.

Material And Methods: Term 55 SGA babies were compared with 200 AGA infants at birth, first and sixth months of ages for both growth parameters and coronary artery diameters measurements.

Calcium metabolism disturbances are common in childhood. In infancy, hypercalcemia generally occurs due to hyperparathyroidism, familial hypocalciuric hypercalcemia, subcutaneous fat necrosis, total parenteral nutrition administration, hyperthyroidism, and adrenal insufficiency. Granulomatous disorders such as tuberculosis and sarcoidosis are rarer cause of hypercalcemia.

Objective: To analyze non benign neonatal arrhythmias (NA) observed in a tertiary neonatal intensive care unit (NICU).

Methods: From June 2006 through July 2011, newborns admitted to the NICU for NA or diagnosed as NA after hospitalization were evaluated retrospectively. The newborns with non benign NA were included in the study.

Objective: Fetal calprotectin levels increase in the early stages of necrotizing enterocolitis. Although the effects of several factors on fetal calprotectin have been studied, the effect of phototherapy is not known. In this study, we analyzed the effect of phototherapy on fetal calprotectin levels.

Chitotriosidase (ChT) is an enzyme secreted by activated macrophages and involved in defense against, and in degradation of chitin-containing pathogens, such as fungi, nematodes, and insects. In addition, it plays an important role in the development of atherosclerosis related with systemic low-grade inflammation. To this effect of activity of ChT, we aimed to investigate serum ChT activity in obese subjects and to determine to relation with insulin resistance and high-sensitive C-reactive protein (hsCRP).

We sought to determine the effect of neonatal transport on the incidence of adverse events of transient tachypnea of the newborn (TTN) in term neonates. A retrospective study was performed of neonates who had TTN and were admitted to Neonatal Intensive Care Unit (NICU) of Sami Ulus Maternity, Children's Education and Research Hospital by land-based transport. Data from 208 newborns with TTN were evaluated, and clinical and laboratory findings were compared between patients who were transported from within the city (group 1) or from outside of the city (group 2).

There are few reports on pandemic swine influenza A (H1N1) virus infection in very young infants. We aimed to discuss the clinical characteristics and management of the H1N1 influenza infection in very young infants. Clinical characteristics of ten infants diagnosed with H1N1 influenza virus infection during the 2009 outbreak season in a tertiary neonatal intensive care unit were evaluated.

Unlabelled: Congenital chylous ascites is a rare condition seen in the neonatal period and the data on pathogenesis and treatment modalities are limited. In this article, we report a case of neonate with chylous ascites and review the therapeutic management procedures on chylous ascites in childhood. We present our experience in the diagnosis and treatment of this condition.
