We investigated the relationship between total serum bilirubin and serum Tau and S100B protein levels, and predicted a cutoff level of bilirubin-induced neurotoxicity in term newborns. Total serum bilirubin, serum Tau, and S100B levels were measured in 92 jaundiced term newborns. A neurologic examination, electroencephalogram, brainstem auditory-evoked(More)
Neonatal seizures can be difficult to classify according to partial vs generalized onset based on clinical appearance, electroencephalogram (EEG) or other adjunctive imaging techniques. Single-photon emission computed tomography (SPECT) has proven to be useful in adults; however, its use is limited in the paediatric age group, particularly in neonates. A(More)
DNA repair plays a key role in prevention of carcinogenesis and one of the most important DNA repair mechanisms is nucleotide excision repair (NER) pathway. This pathway includes a number of genes such as excision repair cross-complementing group 1 (ERCC1) gene which are responsible for the 5′ incision of damaged DNA. A reduced DNA repair capacity(More)
OBJECTIVE The aim of this work was to determine the radiation dose received by infants from radiographic exposure and the contribution from scatter radiation due to radiographic exposure of other infants in the same room. MATERIALS AND METHODS We retrospectively evaluated the entrance skin doses (ESDs) and effective doses of 23 infants with a gestational(More)
BACKGROUND Amplitude-integrated electroencephalogram (aEEG) at <6 h is the best single outcome predictor in term infants with perinatal asphyxia at normothermia. Hypothermia treatment has changed the cutoff values for outcome prediction by using time at onset of normal trace and SWC. Cerebral hemodynamics and oxygenation changes detected by near infrared(More)
Excitatory amino acids, cytokines and nitric oxide (NO) have been studied in the etiology and pathogenesis of hypoxic ischemic encephalopathy (HIE) of the newborn. Vascular endothelial growth factor (VEGF) is a known mediator of angiogenesis and has been shown to induce vascular proliferation and permeability via NO-mediated mechanism during hypoxia. The(More)
Neonatal hypoxic encephalopathy is one of the major causes of permanent neurological sequel. This study was conducted to investigate serum total, free and acylcarnitine levels in asphyxiated newborns with or without encephalopathy. Serum total, free and acylcarnitine levels were investigated in 21 newborns with and seven asphyxiated newborns without signs(More)
The study was designed to investigate the cerebrospinal fluid and serum levels of neuron-specific enolase, along with cranial ultrasonography, magnetic resonance imaging (MRI), and electroencephalography (EEG), for predicting the clinical state and neurologic outcome of 26 asphyxiated term newborns. The babies were graded according to the Sarnat and Sarnat(More)
The aim of this study was to see whether the scores of the Bayley Infant Neurodevelopmental Screener of 45 high-risk preterm infants (gestational age 26-37 wk) between the ages of 3 and 24 months predicted neurodevelopmental status at 7 to 10 years of age. Neurodevelopmental status of 45/122 preterm infants, grouped according to their gestational ages of 26(More)
Preterm ovarian hyperstimulation syndrome (POHS) is an uncommon disorder characterized by prematurity, hypogastric and upper leg swelling of various intensities, high serum estradiol and gonadotropin levels, and ovarian follicular cyst/cysts. In this paper, we present the first case of POHS presenting with vaginal bleeding. A female infant was born via(More)
