道路案内標識で表示される地名を運転者が情報として十分に利用するためには,案内標識の情報を記載した地図を用いて自らが経路と地名の関係を事前に学習しておく必要がある.また,この地図を利用することで,案内標識が設置された経路を選定するなど,地図と連携した案内標識の積極的活用が可能になる.本研究では,こうした観点からシミュレータを用いた室内実験によって,案内標識情報を記載した地図を用いた事前学習の効果を分析した.その結果,地図を用いた事前学習により,地名情報の利用が増加し,予定経路どおりに走行できる割合が向上するばかりでなく,予定経路以外の経路を走行する距離,心理的負担が軽減することが明らかとなった.

Autoimmune inner ear disease (AIED) was reported by McCabe in 1979 and was characterized by episodic vertigo and fluctuating hearing loss. Some patients develop total deafness and severe disequilibrium which disturbs their activities of daily living (ADL). Steroids or immune suppressing agents are used to control symptoms, but they have to be given repeatedly, because the symptoms tend to recur. We analyzed 22 AIED patients diagnosed by the presence of a 68kDa protein. The patients with low grade hearing loss showed some recovery of their hearing, However, hearing recovery was not noted in any patient with severe hearing loss. It is important to diagnose AIED and start treatment as soon as possible.

Intranasal steroids are widely used to treat olfactory disorder, and are known to have fewer side effects than systemic steroids. However, there are some reports that intranasal steroids have induced adrenal insufficiency, even when the steroid dosage is appropriate. We encountered a case of secondary adrenal insufficiency after using intranasal betamethasone for olfactory disorder within the usual dosage. In this case, we were not aware of instructing the patient not to swallow the steroid which had dripped into her pharynx. Thus, a large amount of steroids which had passed through her nasal cavity might have been absorbed in the oropharyngeal mucosa and also ingested. That is possibly the main cause of developing adrenal insufficiency. Recently, Toki-shakuyaku-san, a traditional Chinese medicine, has started to be used for olfactory disorder after a cold. Because of its minimum side effects, it may be safely used for patients with the risk associated with steroid use.

When examining patients with vertigo, it is essential to differentiate between central and peripheral lesions. It has been reported that some infarctions associated with the posterior inferior cerebellar artery (PICA) can mimic peripheral vertigo, such as benign paroxysmal positional vertigo (BPPV). We report on a case that had been treated as BPPV at another institution and eventually turned out to be cerebellar infarction in the PICA legion. Two infarction lesions were observed in the cerebellum. Obstruction of the left vertebral artery was found on MRA. Six months from the first consultation, the BPPV decreased. We should be aware of cases of cerebellar infarction in which nystagmus mimics BPPV.

This study was performed to determine the frequency and degree of sleep disturbance in patients with dizziness using the Pittsburgh Sleep Quality Index, Japanese Version (PSQI-J), and investigate the relationship between dizziness and sleep disturbance. Fifty-two patients (20 male, 32 female) with a chief complaint of dizziness visited the dizziness clinic of the Department of Otolaryngology, Tokyo Medical University, for 3 months in 2013. The patients' age (average ± standard deviation) was 54.4±17.0 years (range, 10-88 years). The average PSQI global score was 7.6±4.2 points, which exceeds the 5.5-point cut-off for insomnia. In total, 67.3% of patients scored >6 points, and 35.8% scored >9 points, indicating definite sleep disturbance. With respect to the demography of disease groups, patients with Meniere's disease scored an average of 7.9 points, those with autonomic imbalance scored 8.8 points, and those with psychogenic dizziness scored 9.7 points; all of these diseases were associated with high PSQI scores. Patients with benign paroxysmal positional vertigo and patients with no abnormal findings showed relatively low scores (6.7 and 5.3 points, respectively). Patients with suspected sleep apnea syndrome, restless leg syndrome, and parasomnias tended to show high scores (>10 points). A high rate and high grade of sleep disturbance were confirmed in patients with dizziness, indicating that sleep quality affects several types of dizziness and vertigo. Understanding sleep disorders is helpful for the diagnosis and treatment of dizziness and provides a new perspective on the etiology of dizziness.
