Congenital diarrheal disorders (CDDs) are a heterogeneous group of inherited diseases that typically occur in the first weeks of life or can present later in life after the introduction of different nutrients; they can cause life-threatening severe dehydration and electrolyte disturbances. This study was conducted to characterize the causes of monogenic CDDs, and their clinical consequences. Clinical characteristics of 31 patients with CDDs that occurred in the first month of life and lasted more than 2 weeks were analyzed retrospectively.

Introduction: Intravenous immunoglobulin (IVIG) has been widely used to treat the hemolytic disease of the newborn (HDN). Although it has been shown that IVIG treatment reduces the duration of phototherapy and hospitalization, the use of IVIG in hemolytic disease due to ABO incompatibility has been controversial in recent years. This study aimed to investigate the role of IVIG in the prevention of exchange transfusion in infants with ABO HDN who presented with bilirubin levels at or above the level of exchange transfusion.

Background: Congenital heart diseases (CHD) are the most common birth defects. Necrotizing enterocolitis (NEC) is an important cause of morbidity and mortality in premature infants, and probiotics can be used to protect NEC.

Case Report: We present a term infant with aortic coarctation who developed sepsis with GG after probiotic use, successfully treated with ampicillin.

Objective: Urinary tract infection (UTI) is a disease that can cause significant complications in the neonatal period. The thiol-disulfide homeostasis is one of the important antioxidant defense mechanisms. The purpose of this study is to show the relationship between UTI and thiol-disulfide homeostasis in newborns.

Urea cycle disorders (UCD), are genetically inherited diseases that may have a poor outcome due to to profound hyperammonemia. We report the case of a baby girl diagnosed as N-acetylglutamate synthase (NAGS) deficiency. The patient was evaluated due to diminished sucking and hypotonicity.

We aimed to understand the efficacy of fennel (Foeniculum vulgare: FV) extract in an experimental necrotizing enterocolitis (NEC) model. Forty-two rat pups were divided into three groups as NEC, NEC treated with fennel extract, and control. At the end of the experiment, tissue samples were taken from the proximal colon and ileum for biochemical and immuno-histological studies including hematoxylin-eosin and Caspase-3-8-9 immunohistochemical staining.

Background/aim: It has been suggested that plasma KL-6 increases in premature infants with bronchopulmonary dysplasia (BPD). We aimed to evaluate the predictive values of KL-6 in BPD.

Materials And Methods: The study was performed in preterm neonates with birthweight ≤1500 g and gestational age ≤32 weeks.

Article Synopsis
  • The study assessed the levels of asymmetric dimethylarginine (ADMA) as a marker of endothelial function in neonates born small for gestational age (SGA) compared to those of appropriate size (AGA).
  • Results showed that SGA neonates had significantly higher ADMA levels, as well as increased carotid intima-media thickness (cIMT) and resistive index (cRI) compared to AGA controls.
  • There was a positive correlation between ADMA levels and cIMT, indicating that higher ADMA may impact vascular health in SGA neonates as they grow.

The aim of this study was to investigate the effects of topotecan, a topoisomerase I-inhibiting anticancer agent, on hematologic parameters and serum levels of trace elements. The study was conducted on three groups consisting of 16 and 18 rabbits in the study groups and 15 rabbits in the control group. Rabbits in group I (n = 16) received high-dose topotecan intravenously (i.
