BACKGROUND/AIMS The aim of this study was to assess the effects of endoscopy nurse participation on polyp detection rate (PDR) and adenoma detection rate (ADR) of second-year fellows during screening colonoscopies. METHODS This was a single-center, prospective, randomized study comparing a fellow alone and a fellow plus an endoscopy nurse as an additional(More)
This study was designed to investigate the mechanisms of action of the 5-HT2 receptor on the spontaneous electrical activity and potassium currents of the rat medial vestibular nuclear neurons using whole-cell patch clamp recordings. The spike width of spontaneous action potential was not affected by 5-alpha-methylhydroxytryptamine. The spike frequency and(More)
In a sample of 235 families with at least two children with Attention-Deficit/ Hyperactivity Disorder (ADHD), the frequency and familial association of learning disabilities (LD) were assessed. Familiality was examined both between sibling pairs and between parents and their children. Two methods for defining LD, a discrepancy-based and a low-achievement(More)
BACKGROUND/AIMS The aim was to compare the insulin sensitivity and secretion index of pregnant Korean women with normal glucose tolerance (NGT), gestational impaired glucose tolerance (GIGT; only one abnormal value according to the Carpenter and Coustan criteria), and gestational diabetes mellitus (GDM). METHODS A cross-sectional study was performed with(More)
A 32-year-old woman with Behcet's disease suffered repeated transient ischemic attacks (TIA) consisting of left hemiparesis. Cerebral angiography revealed the typical findings of moyamoya disease, with occlusion of the supraclinoid portion of both internal carotid arteries, coupled with abnormal collateral vessels. She underwent right superficial temporal(More)
Simultaneous occurrence of aneurysmal subarachnoid hemorrhage (SAH) and hypertensive intracerebral hemorrhage (ICH) is very rare and only two cases have been previously reported in the literatures. We present a case of 68-yr-old man with a history of untreated hypertension, who suffered from sudden onset of headache followed by right hemiparesis. Computed(More)
BACKGROUND There are several reports in the literature of postoperative ischemic events due to swelling of the temporalis muscle after indirect revascularization surgery. Here, we report our surgical technique for preventing ischemic events during the acute postoperative recovery period in moyamoya patients. MATERIAL AND METHODS We used various types of(More)
OBJECTIVE Neuroendoscopy is applied to various intracranial pathologic conditions. But this technique needs informations for the anatomy, critically. Neuronavigation makes the operation more safe, exact and lesser invasive procedures. But classical neuronavigation systems with rigid pinning fixations were difficult to apply to pediatric populations because(More)
OBJECTIVE To report our surgical experience using in situ end-to-side bypass for giant serpentine distal anterior cerebral artery aneurysm, unsuitable for microsurgical clipping. METHODS A 49-year-old woman presented with headache and intermittent loss of consciousness. The brain computed tomography scan revealed a partially calcified mass in the(More)
PURPOSE Current clinical data support a safe warm ischemia time (WIT) limit of 30 minutes during laparoscopic partial nephrectomy (LPN) or robot-assisted partial nephrectomy (RPN). We evaluated independent factors predicting prolonged WIT (more than 30 minutes) after LPN or RPN. MATERIALS AND METHODS A retrospective data review was performed for 317(More)
