PURPOSE The objective of this study was to compare the effects of two neuroprotective agents; melatonin, a free radical scavenger and topiramate, AMPA/kainate receptor antagonist, administered alone or in combination in neonatal hypoxic-ischemic model. METHODS After being anesthetized, 7-day-old pups underwent ischemia followed by exposure to hypoxia. The(More)
BACKGROUND Oxygen-induced lung injury is believed to lead to the development of bronchopulmonary dysplasia in premature infants. We have evaluated the beneficial effects of Nigella sativa oil (NSO) on rats with hyperoxia-induced lung injury. METHODS Thirty newborn Sprague-Dawley rats were randomly divided into 3 groups as hyperoxia (95% O(2)),(More)
BACKGROUND Necrotizing enterocolitis (NEC) is one of the most common gastrointestinal emergencies in newborn infants but up to now there is no completely effective treatment for it. OBJECTIVE In order to show that a combination of melatonin and prostaglandins may be useful to save lives, we use newborn rat as a model of necrotizing enterocolitis to test(More)
Neonatal hypoxic-ischemic encephalopathy (HIE) is a major cause of neurological disability requiring newer therapeutic strategies. Uridine is the principal circulating pyrimidine in humans and a substrate for nucleotides and membrane phospholipids. The objective of this study was to investigate the effects of uridine in a neonatal rat model of HIE. Rat pups(More)
OBJECTIVE Histone acetylation and deacetylation may play a role in the pathogenesis of inflammatory lung diseases. We evaluated the preventive effect of valproic acid (VPA), a histone deacetylase (HDAC) inhibitor, on neonatal hyperoxic lung injury. METHODS Forty newborn rat pups were randomized in normoxia, normoxia+VPA, hyperoxia and hyperoxia+VPA(More)
Acute scrotal abscess is a rare condition in neonates. Most of these abscesses were reported to be unilateral and caused by Staphylococcus and Salmonella spp. Herein, we report a bilateral scrotal abscess in a preterm infant and Candida albicans was isolated from the scrotal fluid culture. To our knowledge, this is the first bilateral scrotal abscess in a(More)
PURPOSE A significant cause of neurological disability in newborns is hypoxic-ischemic encephalopathy (HIE), a disorder which involves an enhancement in histone deacetylase (HDAC) activity among underlying pathological mechanisms. We showed recently that exogenous administration of uridine to newborn rats with HIE reduced brain injury in a dose-dependent(More)
Cardiac rhabdomyoma often shows spontaneous regression and usually requires only close follow-up. However, patients with symptomatic inoperable rhabdomyomas may be candidates for everolimus treatment. Our patient had multiple inoperable cardiac rhabdomyomas causing serious left ventricle outflow-tract obstruction that showed a dramatic reduction in the size(More)
Right atrial appendage aneurysm is a very rare condition which can be asymptomatic or can cause arrhythmia or life-threatening thromboembolism. We report a case of newborn with right atrial appendage aneurysm who was diagnosed with fetal echocardiography. Anticoagulant therapy was applied to prevent thromboembolism and he is still going on follow-up without(More)
