起立性調節不全症候群の脳血流のautoregulationについて, single photon emission computer tomography (SPECT) を用いて検討した.対象は, Schellong検査陽性症例13例で, 対照例として陰性症例4例を検討した. 心電図RR間隔測定を行い, 立位・臥位の2回, SPECTを撮影し, 脳血流の変化率を求めた.自律神経障害はSPECT計測による脳血流には影響を及ぼしていなかつた. 自律神経障害と起立性めまい発現とには相関があつた.自律神経失調による血圧低下に対しても脳血流のautoregulationは保たれていた. めまい発症については, SPECTでは指摘できない内耳のautoregulation障害の可能性も考えられた.

During the past 14 years from 1975 to 1989, two-nation-wide surveys of Meniere's disease have been carried out by the Vestibular Disorders Research Comittee of Japan, supported by the Ministry of Health and Welfare of Japan. However, an epidemiological case-control-study including normal subjects has not yet been performed by this committee.<BR>In this third survey, therefore, 148 patients with definite Meniere's disease, 138 with non-Meniere vertigo, 113 with rhinolaryngological disorders, and 165 normal control subjects were collected by the 16 mem-bers of the Research Committee from June 1990 to November 1990. The controls were selected to match as closely as possible the sex, age and location of the Meniere's disease patients.<BR>The characteristic epidemiological features of Meniere's disease in Japan were :<BR>1) Sex-ratio : 63 males to 85 female.<BR>2) Age-distribution : Peak at 40-49 years for males and 30-39 years for females.<BR>3) Season and Time of Onset : Often initial vertigo attacks occurred in the afternoon or in the morning.<BR>4) Occupational Distribution : There was a higher incidence of Meniere's disease among technicians or white-collar workers than among farmers, laborers engaged in blue-collar work, as in the 1st and 2nd surveys. However, the number of house-wives was lower in this 3rd survey.<BR>5) Personal characteristics : In patients with Meniere's disease, precisionism and neurosis were more frequently observed than in non-Meniere's vertigo.<BR>6) Preceding Events : Mental and physical fatigue before vertigo attacks was frequent in Meniere's disease patients.<BR>These epidemiological features reconfirm that the occurrence of vertigo attacks in Meniere's disease is influenced much more by individual factors than by environmental factors, as was found in the 1st and 2nd Nation-wide surveys. However, a marked difference in sex ratio with female preponderance was found in the 3rd survey.<BR>The incidence of bilateral Meniere's disease was 16.2% (24/148), higher than in the 1st and 2nd surveys.

We investigated the influence of a cold front (CF) on the onset of Meniere's disease (MD) and concluded that the onset of MD was influenced by the passing of a CF. But it was not clear whether patients with MD were stressed by the passing of a CF or the passing of a CF directly influenced the inner ears. Among the patients with MD who visited the Neuro-Otological clinic of the Toyama Medical and Pharmaceutical University Hospital from 1987 to 1992, 67 were sure of the date of the first attack and were chosen for the study. In 36 the first attack was on a day when a CF was passing or on the next day, so they were studied epidemiologically.<BR>1) Age: more of these 36 patients were over 40 years of age than in the group of 31 patients with no definite relationship between CF and MD.<BR>2) Hearing: in the 36 patients hearing was poorer than in the others.

Registered cases of Ménière's Disease collected by the Committee members were studied and classified according to the age of onset and the duration of the disease. The influence of each factors on the vestibular symptoms and hearing impairment was analyzed. Next, the influence of these two factors on the hearing loss of the affected side was studied in 120 cases of definite Ménière's Disease.The results of this study were as follows:1) The hearing impairment of the affected side increased gradually with the age of onset and the duration of the disease.2) The vestibular symptoms of Ménière's disease were not significantly affected by these two factors.
