Sudden deafness without associated neurological symptoms and signs is typically attributed to a viral inflammation of the labyrinth. Although sudden deafness occurs with anterior inferior cerebellar artery (AICA) infarction, the deafness is usually associated with other brainstem or cerebellum signs such as crossed sensory loss, lateral gaze palsy, facial(More)
In Experiment 1, subjects sought to localize the nostril stimulated, left or right, in tests with nine esters (acetates, propionates, and butyrates) at concentrations meant to trigger chemesthesis (pungency, irritation). The task produced psychometric functions for chemesthetic detection unconfounded by olfactory sensations. The functions indicated a sharp(More)
Many neurologists are unaware of the drop attack that may occur from an inner ear dysfunction especially in elderly. We studied the clinical features and results of quantitative audiovestibular tests in six elderly patients (> or =65 years of age) who presented with drop attacks attributable to an inner ear pathology. Group was divided into Meniere's(More)
Human respiratory syncytial virus (HRSV) is the most common respiratory pathogen among infants and young children. To investigate the prevalence and genetic characteristics of HRSVs circulating in South Korea, we analyzed medical records of patients and performed molecular analysis of the G-protein gene of viruses detected from nasopharyngeal aspirates(More)
BACKGROUND There has been no systematic study that carefully investigates the characteristic features of abnormal cervical vestibular-evoked myogenic potential (cVEMP) response associated with the AICA territory infarction. OBJECTIVES To investigate the frequency, the characteristic patterns of abnormal cVEMP associated with AICA territory infarction, and(More)
Berberine, an isoquinoline alkaloid with a long history of use in Chinese medicine, has several important pharmacological effects. Several studies have revealed that berberine has neuroprotective and neuropsychiatric effects. However, there are few reports regarding the protective effect of berberine against neuronal damage following transient global(More)
