OBJECTIVES/HYPOTHESIS Benign paroxysmal positional vertigo (BPPV) frequently occurs in females over 50 years old, suggesting that a postmenopausal decrease in estrogen secretion might be involved in its onset. An estrogen deficiency is generally known to cause osteoporosis through a reduction in bone mass. This study was designed to investigate a clinical(More)
Two cases of hypertrophic pachymeningitis (HP) associated with pulmonary silicosis in tunnel workers are described. In both cases the myeloperoxidase antineutrophil cytoplasmic autoantibody (MPO-ANCA) was positive. Two patients with pulmonary silicosis developed headache and neurological disturbance, and a diagnosis of HP was made. In both cases the serum(More)
OBJECTIVES/HYPOTHESIS Metabolic syndrome (MetS) is a condition that increases the risk of coronary artery disease and cerebral infarction. We determined the prevalence of MetS in vertigo patients and clinically investigated the association between MetS and vertigo. STUDY DESIGN Case-control study. METHODS The subjects were 333 patients, including 107(More)
To explore the relationship between metabolic syndrome and vertigo, we measured waist circumference, plasma glucose, triglycerides and blood pressure in 333 subjects aged 20-79 years with vertigo. We found overall metabolic syndrome prevalence defined by Japanese diagnostic criteria to be 13.2%, similar to that in other national surveys by the Japanese(More)
OBJECTIVE Syndromal vertigo is defined as a combination of vestibular function disturbance and cranial nerve or cerebral function disturbance. There is evidence that MR angiography (MRA), providing angiogram-like images of the intracranial and extracranial arterial flow, could replace invasive methods for diagnosing central vertigo. The purpose of this(More)
This study was performed to determine whether a novel treatment was effective against cupulolithiasis associated with benign paroxysmal positional vertigo (BPPV) of the lateral semicircular canal, which is characterized by apogeotropic direction-changing nystagmus. We herein describe our head-tilt hopping (HtH) exercise, which is designed to release(More)
We report horizontal canal BPPV (HC-BPPV) targeting its pathophysiology, the affected side, and the function of the horizontal semicircular canal, together with a review of the literature. Subjects were 13 patients with HC-BPPV visiting our vertigo outpatient clinic at Nara medical university hospital and a related hospital in the 2.5 years from January(More)
This report deals with factors which trigger motion sickness. The author has focused on the clinical examinations applied to motion sickness cases. Relationships between clinical data and susceptibility to motion sickness were investigated. The following results were obtained: 1. CV R-R(coefficient of variation of R-R intervals on EGG)in the frequent motion(More)
