Seventeen patients with central vertigo that began with vertigo, seen between 2000 and 2008 at the Department of Otorhinolaryngology of Osaka Medical College Hospital, were investigated. The patients included 14 males and three females. Their mean age was 59.2 years (range 27-82). The cases consist of six cerebellar infarctions, two anterior inferior cerebellar artery (AICA) syndromes, two Wallenberg syndromes, two medial longitudinal fasciculus (MLF) syndromes, three other brain-stem infarctions, one viral encephalitis, and one acute cerebellar ataxia. Thirteen cases (77%) had a history of a disorder that might reduce the cerebral blood flow, and six (46%) had multiple risk factors. The mean interval between the appearance of symptoms and the first visit to our hospital was 6.5 days, and it took 3.8 days to reach a diagnosis. Eleven patients (65%) were transported to hospital by ambulance. Seven (41%) had a delayed neurological abnormality other than vertigo. Nystagmus that was seen at the first visit suggested central vertigo in seven cases and peripheral vertigo in seven cases. In four cases (24%), the nystagmus changed over time, and initially three patients had nystagmus that suggested peripheral vertigo. In some cases, we made the diagnosis based on a neurological abnormality other than vertigo. In other cases, the diagnosis was based on the discordance between the neuro-otological findings and disturbed equilibrium that was inconsistent with peripheral vertigo. When diagnosing central vertigo that began with vertigo, it is important to consider not only neurological abnormalities but also neuro-otological findings and a balance disorder that cannot reasonably be explained as peripheral vertigo.

本研究は,石巻市における避難訓練の結果を報告するものである.2015 年11 月15 日(日曜日,天候:雨)に石巻市総合防災訓練において,各避難所と災害対策本部の情報共有を支援し,効率的な避難所運営を実施することを目的として避難所情報共有システムCOCOA を用いた検証を行った.COCOA は沼田研究室が開発している避難所情報共有システムである.本訓練により,各避難所における避難者数をリアルタイムに把握でき,効率的に避難者名簿も作成されるため要配慮者の把握も容易にできるなど,時系列的な状況変化に応じた効率的な避難所運営が実施できることが確認できた.
