To expand current knowledge on febrile seizures (FSs), the most common childhood seizure disorder, we investigated clinical features and risk factors of FS in the pediatric emergency department of a center in western Seoul. Children with FS that visited the pediatric emergency room of the Ewha Womans University Medical Center from January to December 2014 were included in this study. A retrospective medical record review was conducted for a total of 404 seizure events relative to 265 patients. A total of 150 boys and 115 girls were enrolled. Children presenting their first FSs were 70.9% (n=188). Average age of FS onset was 28.9 months. Family history was reported in 95 children (36.8%) with higher relevance of paternal inheritance (44.2%, n=42/95). More than half of the seizures (56.4%, n=228/404) occurred on the first day of fever. The most common cause of fever was upper respiratory tract infection (65.8%, n=266/404). Children attending a daycare center had higher incidence of multiple FS compared to those cared for at home. Approximately one third of seizure events (31.7%, n=128/404) were admission cases, mainly because of prolonged fever. FS is a common neurologic disorder with relatively high admission rate among pediatric emergency department visits. Daycare attendance is associated with current increased incidence of multiple FS. Further study with long-term follow up is necessary to expand knowledge on improving clinical care strategy in FS.

Kawasaki disease (KD) is the self-limited and multisystem vasculitis which accompanies many complications. Ophthalmic findings in KD are bilateral conjunctival injection, iridocyclitis, superficial keratitis, vitreous opacities and subconjunctival hemorrhage. Optic disc swelling is a rare ophthalmic complication in KD. We describe a 3-year-old boy who presented with 7 days of fever, both conjunctival injection without discharge, and right cervical lymph node enlargement of more than 1.5 cm. He was diagnosed as incomplete KD. He had no ocular symptom except bilateral conjunctival injection. On ophthalmic examination, he was diagnosed by anterior uveitis with optic disc swelling. The brain magnetic resonance imaging was performed and revealed no evidence of increased intracranial pressure. Echocardiography revealed the dilated right coronary artery up to 3.4 mm. Fever subsided and optic disc swelling was completely improved after intravenous immunoglobulin (2 g/kg) treatment. Optic disc swelling is a rare ophthalmic complication in KD.

Spontaneously hypertensive rats (SHR) are frequently used as rat models of essential hypertension. The mechanism for the development of hypertension is complicated and it is unknown. The renin-angiotensin system (RAS) plays a key role in the control of blood pressure. Microarrays are a powerful tool for studying genetics. The purpose of this study was to investigate changes of gene expression in the heart tissues of SHR after losartan treatment to provide basic data that is useful in the early diagnosis of hypertension and gene treatment. Rats were divided into three groups: the control (C) group; the hypertension (H) group (SHR), and the losartan (L) group; treated with losartan (10 mg/kg/day) in SHR. Rats were sacrificed at week 5 and microarray analysis was performed. 102 gene expressions including the genes associated with cell proliferation such as According to microarray analysis, there was significant gene expression change in SHR compared with normal rats as well as significant gene expression changes after losartan treatment in SHR.
