PURPOSE To evaluate the cognitive and behavioral effects of topiramate (TPM) versus carbamazepine (CBZ) using efficacious doses of each drug as monotherapy for children with benign rolandic epilepsy. METHODS A multicenter, randomized, open-label, observer-blinded, parallel-group clinical trial was conducted. TPM was introduced at a dose of 12.5 mg/day(More)
BACKGROUND Actigraphy has become an important tool in sleep research, however, most actigraphic models have had little evaluation of their sleep scoring software. Some reports have described poor agreement of actigraph and polysomnogram (PSG) results. In this study, we examined the accuracy of the Actiwatch-L instrument with Actiware((R)) software version(More)
The prevalence of pediatric obstructive sleep apnea syndrome (OSAS) is approximately 3% in children. Adenotonsillar hypertrophy is the most common cause of OSAS in children, and obesity, hypotonic neuromuscular diseases, and craniofacial anomalies are other major risk factors. Snoring is the most common presenting complaint in children with OSAS, but the(More)
Galpha(h), also known as transglutaminase II, has GTPase as well as transglutaminase activities. To better understand the factors affecting these dual enzymatic activities, we examined the optimal pH (at 25 degrees C) and thermal stability (at 37 degrees C) of the activities using membranous Galpha(h) from mouse heart. The optimum pH for the GTPase activity(More)
PURPOSE Korean adolescents have severe nighttime sleep deprivation and daytime sleepiness because of their competitive educational environment. However, daytime sleep patterns and sleepiness have never been studied using age-specific methods, such as the pediatric daytime sleepiness scale (PDSS). We surveyed the daytime sleepiness of Korean adolescents(More)
Plate-like osteoma cutis (PLOC) is a dermatological disorder characterized by superficial ossification and rarely occurs without any underlying tissue abnormalities or pre-existing calcification. The hereditary form of PLOC is mainly due to inactivating mutation in the GNAS gene. Inactivating mutation of the GNAS gene is associated with several diseases,(More)
We conducted a case-control study to investigate whether vascular endothelial growth factor (VEGF -2578, -1154, -634, and 936) and kinase insert domain containing receptor (KDR -604, 1192, and 1719) polymorphisms are associated with moyamoya disease. Korean patients with moyamoya disease (n = 107, mean age, 20.9±15.9 years; 66.4% female) and 243 healthy(More)
We investigated the neuroprotective effects of human placental extracts (HPE) and the effects of HPE on recovery of cognitive and behavioral function on hypoxic-ischemic brain injury in the newborn rat. The right common carotid arteries of 7-day-old rats were coagulated, and rats were then exposed to 8% oxygen. Immediately before and again at three times(More)
PURPOSE Sleep onset association disorder (SOAD) is a form of behavioral insomnia observed in children that is caused by inappropriate sleep training. SOAD typically disturbs the sleep of not only infants and children but also their parents. We investigated levels of depression and marital intimacy among parents of infants with typical SOAD, to understand(More)
BACKGROUND It is unclear as to whether sleep respiratory breathing disorder (SRBD) is a risk factor for uncontrolled asthma in children. The aim of this study was therefore to investigate whether SRBD may have an adverse effect on childhood asthma control and lung function measures. METHODS This was a cross-sectional study of 220 children with(More)
