Forty patients of an acute low-tone sensorineural hearing loss (ALHL) were studied based on their clinical diary in which the patients described six subjective symptoms such as tinnitus, ear fullness, autophonia, headache and dizziness.Twenty-one patients complained of fluctuation of subjective symptoms in during a day. In seven cases, decrease of the fluctuation of subjective symptoms were observed as ALHL has been improved.The fluctuation of hearing or the relapse of hearing loss was indicated by audiograms in twenty-two patients. Audiograms in some cases did not correlate to their subjective symptoms.As it is difficult to perform frequent audiograms in the patients of ALHL, the clinical diary as well as the audiogram are very useful to study the clinical course of ALHL.

250Hzから4000Hzまでの5周波数聴力閾値の平均が40dB未満 (grade1) の突発性難聴症例について検討した。高度の感音難聴ではないことから, 突発性難聴以外にオージオグラムの型により急性低音障害型感音難聴, 急性感音難聴といった診断がなされており, 担当医の違いにより診断が影響されていた。予後については, 治癒率は66%であったが, 著明回復は1例も見られなかった。これは, 著明回復が30dB以上の改善と定義されているためで, grade1ではこれは治癒と重なってしまうためと考えられた。突発性難聴にgrade1症例を含めるかどうかの是非を含め, 難聴の程度に応じた診断基準, 聴力回復の判定基準の作成が望まれた。

We studied 50 patients with acute low-tone sensorineural hearing loss (ALHL) who were examined at the Department of Otolaryngology, University of Tokyo, and followed up for 18 months or more. We investigated the prognosis of hearing loss within 3 months after onset, rate of recurrence during long-term follow-up, interval between the first and the second episodes of hearing loss or between onset and the time when the diagnosis of Meniere's disease was made, and factors affecting prognosis.<br>The results were as follows.<br>1. Within the initial 3 months of follow-up, hearing loss continued to fluctuate in 5 patients. In the remaining 45, hearing returned to normal in 34, improved without returning to normal in 6, showed no marked change in 4, and became worse in one.<br>2. In long-term follow-up, the recurrence of hearing loss without vertigo occurred in 16 patients, and 5 others were eventually diagnosed as having Meniere's disease. The average interval between the first and second episodes of hearing loss was 9.2 months, and the diagnosis of Meniere's desease was made an average of 27 months after onset.<br>3. Recurrence was not significantly related to the initial prognosis of hearing loss.<br>4. Within the initial 3 months of follow-up, the prognosis of hearing loss was significantly better in patients whose hearing loss at 1kHz was within 20dB, and tended to be better in females and in patients attending within one week of onset. Long-term follow-up showed that the rate of recurrence was significantly lower in patients aged 40 years or more, and tended to be lower in patients who visited the hospital within one week of onset or whose hearing loss at 1kHz was within 20dB.<br>5. There were no significant differences between patients with single and recurrent attacks with respect to sex, subjective symptoms, and results of the glycerol test and electrocochleography.<br>ALHL tends to recur without any relationship to the initial prognosis of hearing loss. Since it is still difficult to predict whether or not hearing loss will recur, long-term follow-up is necessary even in patients with good initial prognosis.

To evaluate the effectiveness, safety and utility of Emedastine difumarate (ED) in the treatment of Japanese cedar pollinosis, a multicentered, double-blind comparative study was performed in 290 patients in 1994.<br>Patients with Japanese cedar pollinosis were divided into two groups; the first group was treated with ED at a dose of 4mg/day starting two weeks before the season and continuing for the whole season. The second group was given an inactive placebo instead of ED during the pre-season and the early portion of the season and then replaced with ED during the later portion of the season.<br>As a result, the final improvement rate was significantly higher in the first group than that in the second group.<br>All subjective symptoms such as sneezing, nasal discharge, nasal obstruction and eye itching were suppressed due to ED treatment.<br>In conclusion, it was better to continuously administer ED to patients with pollinosis from the preseasonal period till the end of the season.<br>However, when the ED treatment was started in the midseason, the outcome was good, although less satisfactory than the outcome of continuous treatment given throughout the entire pollen season.
