Laryngeal stenosis is caused by various reasons and we are usually able to detect a cause in many cases. Occasionally we encounter a case without an obvious cause. Recently we observed such a case, and we suspected that chlorine detergent possibly caused it. The patient was a 66-year-old female whose main complaint was stridor. She had been using chlorine detergent everyday for about ten years. She had been diagnosed and treated for bronchial asthma because of the stridor. Subsequently, supraglottic stenosis was observed and it was caused by this lesion. There was no particular past history and no distinguishing pathological character in the stenosis lesion. The stenosis was removed by laryngo-fissure with a supra-hyoid approach while a surgical lumen was maintained using a core mold. She stopped using the detergent after the treatment. After sixteen months of follow-up since the operation, the patient has shown no evidence of recurrent disease.

睡眠時無呼吸の病因ならびに長期治療成績を左右する因子として, 睡眠体位と肥満は重要である.肥満と体位の及ぼす影響を, 気道内圧測定を含む睡眠検査を実施した68例(平均年齢: 47.2歳, 平均肥満度: 120.5%)について検討した.68例をやせ群(肥満度90%未満)+普通体重群(肥満度90%以上, 110%未満), 過体重群(肥満度110%以上, 120%未満), 肥満群(肥満度120%以上)の3群にわけた.肥満群の無呼吸+低換気数(AHI)は47.1/hr.で, やせ・普通体重群(32.6/hr.), 過体重群(31.3/hr.)に比し有意に高値であった.また肥満群の最低酸素飽和度値は80.1%で, やせ・普通体重群(85.0%), 過体重群(85.8%)に比し, 有意に低値であった.食道内圧変動値に関しては, 肥満群45.4cm H20, やせ・普通体重群33.5cm H20, 過多体重群32.5cm H20であった.側臥位の検討では, 肥満群は, 仰臥位と同様, やせ・普通体重群に比しAHI, 食道内圧変動値が有意に大きい値であった.側臥位での呼吸障害の改善度は, その肥満度に反比例していた.また仰臥位から側臥位に体位変換することで, AHIと食道内圧変動値がともに50%以上減少した症例数は67例中30例(44.8%)であった.

The purpose of this study was to examine the fusion area in a real image and binocular disparity when the viewing distance was changed. As a result, when the viewing distance was short, the fusion area in the real image increased. However, the fusion area in the binocular disparity image did not increase as it did in the real image. Since the depth of field with the real image was shallow when the viewing distance was short, it was easy to perceive blurring. In binocular disparity images, since images of the front and back are not blurred, it is impossible to expand the fusion area of binocular disparity, to confirm whether it is expanded by blurring, we measured the fusion area when the binocular disparity image is blurred. As a result, the fusion area of binocular disparity was wider than in the real image when binocular disparity image was blurred.

The great development of computers and their rconnected terminals is producing the development of image technology and also the easy operation by networks for users. Given assistance of the special fiscal 1988 and 1989 budgets in the Faculty of Engineering, Tokyo Institute of Polytechnics, this project started in cooperation with the laboratories interested in the application of the image information. In order to fulfill graphic functions and image processor simultaneously by one system, which will be the most powerful research tool in the near future, IRIS 4D/50GT graphic computer and NEXUS image processor were purchased and connected with VME BUS so that a part of the multi-functional system was completed. As several analysis about the information of the three-dimensional image were conducted using the system, the abstract is reported.
