Importance: The long-term effects of surfactant administration via a thin catheter (minimally invasive surfactant therapy [MIST]) in preterm infants with respiratory distress syndrome remain to be definitively clarified. Objective: To examine the effect of MIST on death or neurodevelopmental disability (NDD) at 2 years' corrected age. Design, s...

Hemolytic disease of the fetus and newborn can cause hydrops and intrauterine death due to fetal anemia. Immunoglobulin and plasmapheresis have been used to defer blood transfusions to later gestational ages and treat fetal anemia in patients who were immunized early in pregnancy, with different success.

Importance The benefits of surfactant administration via a thin catheter (minimally invasive surfactant therapy [MIST]) in preterm infants with respiratory distress syndrome are uncertain. Objective To examine the effect of selective application of MIST at a low fraction of inspired oxygen threshold on survival without bronchopulmonary dysplasia (...

Necrotizing enterocolitis (NEC) is one of the most common gastrointestinal emergencies in the newborn infant, and the incidence varies between 3% and 15% in neonatal intensive care units (NICU). It has a high risk of mortality and both short- and long-term morbidity which severely impacts the quality of life in the survivors. Lack of specific clini...

Objective: To evaluate if the number of admitted extremely preterm (EP) infants (born before 28 weeks of gestational age) differed in the neonatal intensive care units (NICUs) of the SafeBoosC-III consortium during the global lockdown when compared to the corresponding time period in 2019. Design: This is a retrospective, observational study. Forty...

Background: Necrotizing enterocolitis (NEC) is an important cause of morbidity and mortality in preterm infants. There is limited data about the role of mesenteric oxygenation status during the first enteral feeding. Therefore, the aim of this study was to determine the mesenteric tissue oxygen saturation values before, during and after the first...

Micafungin is recommended especially in patients with liver and kidney failure and in the presence of other side effects due to antifungals apart from its known priority indications such as invasive candidiasis. The aim of this study was to evaluate the children who have received micafungin treatment. In the study, 125 children who were hospitalize...

Objective: To evaluate whether antenatal magnesium sulphate (MgSO4) exposure has a neuroprotective effect against hearing impairment in premature newborns. Materials and methods: Retrospective cohort study performed with prematurely (<37 weeks) delivered newborns at a tertiary university hospital. Newborns of 92 women who received MgSO4 infusion...

INTRODUCTION: Insulin-like growth factor-1 (IGF-1) is important for fetal and postnatal development. After premature births, serum IGF-1 concentrations rapidly decrease and can stay at much lower levels than during the intrauterine period. In this study, we aimed to ascertain whether IGF-1 is associated with morbidities of prematurity such as bronc...

Özkan H, Köksal N, Doğan P, Güney-Varal İ, Bağcı O, Özgür T. The effectiveness of serum amyloid A for prediction of neonatal cholestasis associated with parenteral nutrition in premature infants. Turk J Pediatr 2019; 61: 26-33. Parenteral nutrition (PN) has been widely used in premature infants untill enteral feeding can be tolerated. Cholestasis i...

Z GİRİŞ ve AMAÇ: Prematüre bebeklerde yüksek miktarda proteinin ilk gün başlanması ile büyüme ve nöromotor gelişimin olumlu etkilendiği bildirilmiştir. Ancak yüksek protein miktarının biyokimyasal parametreler üzerine etkisi tam olarak bilinmemektedir. Bu çalışmada prematüre bebeklerde düşük ve yüksek doz protein uygulamasının biyokimyasal parametr...

İstanbullu K, Köksal N, Çetinkaya M, Özkan H, Yakut T, Karkucak M, Doğan H. The potential utility of real-time PCR of the 16S-rRNA gene in the diagnosis of neonatal sepsis. Turk J Pediatr 2019; 61: 493-499. The purpose of this study was to evaluate the efficacy of real-time polymerase chain reaction (PCR) of the 16S rRNA gene in diagnosis of neonat...

This study aimed to measure aluminum contamination of parenteral nutrition (PN) solutions and aluminum contents of parenteral products given to newborn infants for nutrition or treatment. In this study, the aluminum content of the first products used to prepare PN solutions for premature neonates, of the final parenteral products prepared therefrom...

Güney-Varal İ, Köksal N, Özkan H, Bağcı O, Doğan P. The effect of early administration of combined multi-strain and multi-species probiotics on gastrointestinal morbidities and mortality in preterm infants: A randomized controlled trial in a tertiary care unit. Turk J Pediatr 2017; 59: 13-19. Necrotizing enterocolitis (NEC) is a gastrointestinal em...

Yılmaz C, Köksal N, Özkan H, Dorum BA, Bağcı O. Low serum IGF-1 and increased cytokine levels in tracheal aspirate samples are associated with bronchopulmonary dysplasia. Turk J Pediatr 2017; 59: 122-129. Despite developments in the perinatal and neonatal care, bronchopulmonary dysplasia (BPD) is still the most frequently seen long-term complicatio...

Sacrococcygeal teratoma (SCT) is rarely associated with syndromes. We report a female newborn with a prenatal diagnosis of small sacrococcygeal teratoma and postnatally diagnosed as having trisomy 13. The sacrococcygeal teratoma was excised. It was reported as mature teratoma. The child succumbed to sepsis postoperatively.

Introduction: To determine the rate, etiology and morbidity association of disorders of thyroid function tests (TFTs) in premature babies. Materials and Methods: A total of 139 premature babies who were admitted to Uludag University Faculty of Medicine Hospital Neonatal Intensive Care Unit between January 2009 and January 2012 were included in this...

Introduction: To evaluate babies diagnosed as congenital heart disease in terms of frequency, risk factors and prognosis and to determine the issues to be covered to reduce the mortality in these patients in the scope of the literature. Materials and Methods: Ninety-nine patients diagnosed as congenital heart disease were enrolled among 1.175 patie...

Enterococci are one of the major agents of community-acquired and nosocomial infections. In this study we aimed to analyze the clonal relation of the vancomycin-resistant Enterococci outbreak seen at the Neonate Intensive Care Unit (NICU) of Uludag University Hospital. Vancomycin resistance gene was investigated in the Enterococcus faecium strains...

The Neonatal Multiple Organ Dysfunction (NEO-MOD) scoring system is used to predict mortality in infants with multiple organ dysfunction syndrome (MODS). The NEOMOD scoring system was extended to include involvement of the microvascular system. This modified scoring system was developed to enable more accurate and earlier diagnosis of MODS in prema...

The aim of this study was to determine the value of pro- and anti-inflammatory cytokine levels in both blood and tracheal aspirate (TA) samples that were obtained within 24 h after birth for predicting bronchopulmonary dysplasia (BPD) development in premature infants. Premature infants, who were born before 32 weeks of gestation, weighing less than...
