Non-contrast enhanced computed tomography (NCCT) is usually performed to estimate bleeding complications immediately after procedures. However, hyperdense areas on NCCT have not yet been understood; different interpretations have been reported in the literature. It remains unclear whether NCCT performed immediately after intra-arterial revascularization(More)
OBJECTIVES Inflammatory cytokines are implicated in the pathophysiology of both stroke and depression, and their production is influenced by the transcriptional activity of particular gene polymorphisms. We hypothesised that alleles related to higher pro-inflammatory and/or lower anti-inflammatory cytokine production would be associated with post-stroke(More)
BACKGROUND Human infection with Streptococcus suis (S. suis), a zoonotic pathogen, has been reported mainly in pig-rearing and pork-consuming countries. Meningitis is the most-common clinical manifestation and is often associated with deafness and vestibular dysfunction. CASE REPORT A 57-year-old man was referred to the hospital with headaches, fevers,(More)
Astrocytes become reactive after central nervous system injury, re-expressing glial fibrillary acidic protein (GFAP), vascular endothelial growth factor (VEGF), and nestin. Hypoxia-inducible transcription factor alpha (HIF-1α) is an important transcription factor for several genes including the VEGF and nestin genes, the expression of which generate(More)
We aimed to elucidate whether the eNOS T-786C mutant allele is implicated in subarachnoid hemorrhage (SAH) susceptibility or vasospasm after SAH, and whether the mutant allele is differentially expressed in those with small and large ruptured aneurysms in Korean population. 136 consecutive patients diagnosed with aneurismal SAH and 113 controls were(More)
18F-FDG PET/CT can acquire both anatomical and functional images in a single session. We investigated which factors of 18F-FDG PET/CT imaging have potential as biomarkers for an increased risk of ischaemic stroke in cancer patients. From among cancer patients presenting with various neurological symptoms and hemiparesis, 134 were selected as eligible for(More)
BACKGROUND AND PURPOSE Percutaneous transluminal angioplasty (PTA) is being increasingly used in the treatment of symptomatic middle cerebral artery (MCA) stenosis. We evaluated the long-term durability after PTA for symptomatic MCA stenosis. METHODS We analyzed consecutive patients included in our stroke database who were treated with angioplasty alone.(More)
BACKGROUND It is still controversial whether intravenous (IV) thrombolysis for acute ischemic stroke increases the risk of aneurysmal bleeding. We sought to find the risk for aneurysmal bleeding after IV thrombolysis in ischemic stroke patients with unruptured cerebral aneurysms. METHODS We retrospectively analyzed consecutive patients with acute ischemic(More)
Familial hypokalemic periodic paralysis is an autosomal-dominant disorder with features of both genetic and phenotypic heterogeneity. Mutation screening was performed on Korean hypokalemic periodic paralysis patients to locate the corresponding mutations and to specify the clinical features associated with the mutations. Target-exon PCR, direct sequencing,(More)
BACKGROUND Brain derived neurotrophic factor (BDNF) has been shown to play an important role in poststroke recovery. BDNF secretion is influenced by genetic and epigenetic profiles. This study aimed to investigate whether BDNF val66met polymorphism and promoter methylation status were associated with outcomes at two weeks and one year after stroke. (More)
