BACKGROUND AND OBJECTIVE The incidence of hypoxic ischemic encephalopathy (HIE) in developed countries is estimated to be 1.5 per 1000 live births. The primary aim of this study was to analyze whether earlier hypothermia (≤1 h) improves hospital outcomes in survivors who underwent therapeutic hypothermia (TH) when compared with late TH (>1 h). METHOD(More)
BACKGROUND The aim of this study was to elucidate the specific clinical characteristics associated with abnormal brain magnetic resonance image(MRI) findings in hypoxic ischemic encephalopathy(HIE) infants in order to discern how to predict poorer outcomes more accurately. METHODS A retrospective data analysis of HIE infants admitted to the neonatal(More)
This study aimed to determine whether primary surgical closure of patent ductus arteriosus (PDA) is a risk factor for morbidity and mortality compared with secondary surgical ligation. The study enrolled 178 very-low-birth-weight infants. The surgical group included 34 patients who did not respond to pharmacologic intervention and eventually required(More)
BACKGROUND We aimed to determine the echocardiographic parameters that can predict the presence of patent ductus arteriosus (PDA) and haemodynamically significant ductus arteriosus (HSDA) at different time points. METHODS Echocardiogram was performed on postnatal days 3 and 7(D3-Echo and D7-Echo, respectively) in 71 very low birthweight infants with a(More)
BACKGROUND While developed countries seek to lower the gestational age and birthweight parameters in retinopathy of prematurity (ROP) screening, older, larger infants still develop ROP in other parts of the world. The aim of this study was therefore to define criteria to identify potential ROP developers who are outliers of the common screening range. (More)
The present study examined whether early patent ductus arteriosus (PDA) surgical ligation at ≤2 weeks of life was associated with increased morbidities and mortality in very low birth weight infants (VLBWIs) who were diagnosed with hemodynamically significant (hs) PDA. Between December 2013 and December 2015, a total of 407 VLBWIs were admitted, of whom 145(More)
PURPOSE The effects of therapeutic hypothermia (TH) on hemodynamics in newborns with hypoxic-ischemic encephalopathy (HIE) were evaluated. MATERIALS AND METHODS Thirty-two neonates (gestational age, 39.4 ± 1.3 weeks) who had TH for HIE and echocardiographic hemodynamic assessments during TH and post-TH period were studied. Gestational-age-matched 34(More)
We examined whether hydrocortisone exposure≤1week in very low birth weight infants (VLBWI) was associated with poor neurodevelopmental outcomes at corrected 18months. Further, the clinical factors associated with worse long term outcome were also evaluated. Of a total of 191 VLBWI, the clinical data for these infants relating were retrospectively collected(More)
AIM Neonatal hypoxic ischemic encephalopathy (HIE) patients are at times accompanied by persistent pulmonary hypertension (PPHN), which is by itself another risk factor of adverse outcomes. We aimed to assess the outcome of therapeutic hypothermia (TH) in these patients whom we managed to reverse the shunt flow, as they are expected to be at much higher(More)
PURPOSE Biomarkers may predict neurological prognosis in infants with hypoxic-ischemic encephalopathy (HIE). We evaluated the relationship between serum lactate dehydrogenase (LDH) and brain magnetic resonance imaging (MRI), which predicts neurodevelopmental outcomes, in order to assess whether LDH levels are similarly predictive.
