OBJECTIVES Reportedly, hippocampal neuronal degeneration by kainic acid (KA)-induced seizures in rats <14 days old was enhanced by lipopolysaccharide (LPS). This study was to test the hypothesis that cytokines such as interleukin (IL)-1β, IL-6 and tumor necrosis factor-α are associated with aggravated neuronal damage. MATERIALS AND METHODS Sixty male(More)
BACKGROUND/AIMS An increase in the pulsatility index (PI) has been suggested to reflect distal vascular resistance. The purpose of the present study was to investigate the association between intracranial arterial calcification and intracranial PIs. METHODS Consecutive patients with acute ischemic stroke or transient ischemic attack were included. The PIs(More)
Painless legs and moving toes is an unusual syndrome, which has not previously been reported as an initial presentation of ischemic stroke. We encountered a 78-year-old woman who developed dysarthria and involuntary movement of her left toes that was clinically regarded as painless legs and moving toes. These symptoms appeared abruptly and simultaneously as(More)
Dentatorubral-pallidoluysian atrophy (DRPLA) is an autosomal dominant neurodegenerative disease clinically characterized by the presence of cerebellar ataxia in combination with variable neurological symptoms. Cerebral white matter involvement of DRPLA is rare and reported mainly in severe, progressed cases of old-aged or juvenile-onset DRPLA. We describe(More)
3. Aronne LJ. Classification of obesity and assessment of obesity related health risks. Dear Editor, We appreciate the thoughtful comments regarding the article entitled " Evaluation of anterior segment parameters in obesity " [1], recently published in the Korean Journal of Ophthalmology. We agree with the comments on the relevance of description of(More)
BACKGROUND Previous diffusion-weighted MRI (DWI) studies have indicated that 10-40% of patients have silent embolism during neurointerventional procedures. However, lesion patterns of the embolisms have not been adequately investigated. METHODS DWI was taken within 7 days before and 48 h after cerebral angioplasty and stent procedures. New lesions on the(More)
OBJECTIVE Autonomic symptoms are commonly observed in patients with Parkinson's disease (PD) and often limit the activities of daily living. The Scale for Outcomes in Parkinson's disease-Autonomic (SCOPA-AUT) was developed to evaluate and quantify autonomic symptoms in PD. The goal of this study was to translate the original SCOPA-AUT, which was written in(More)
BACKGROUND AND PURPOSE The objective of this study was to determine diagnostic and prognostic values of proximal radial motor conduction in acute compressive radial neuropathy. METHODS Thirty-nine consecutive cases of acute compressive radial neuropathy with radial conduction studies-including stimulation at Erb's point-performed within 14 days from(More)
Most reported cases of paroxysmal kinesigenic dyskinesia (PKD) are idiopathic or familial; however, hypoparathyroidism is another unusual cause of secondary PKD. The pathomechanism of PKD remains poorly understood, and the association between idiopathic and secondary PKD remains an enigma, and has yet to be clearly elucidated. We recently encountered a(More)
