Recently attention has been focused on countermeasures against microorganisms such as viruses and microbe, in connection with pandemics of new forms of influenza or SARS, and the occurrence of bioterrorism. Also, in pharmaceutical or food production facilities, a high standard of internal environment of the facility is required, including countermeasures against microorganisms. These countermeasures from the facility point of view include partitioning of work zones (zoning), and cleaning the air using HEPA filters. However, when workers/researchers are working within a facility, dispersion of dust or adhering microbe brought in from clothes, etc., cause pollution of the air. In this report, the sterilization performance of weak acid hypochlorous solution used as the chemical substance was verified. In addition, the sterilization performance in an actual space varied not only with the chemical substance used, but also with the condition of the room, the air conditioning system, the method of spraying, etc. Therefore, from the above sterilization performance tests using chemical substances, the raw data required for a computational fluid mechanics (CFD) model were derived. A method that enables the effect of the chemical substance to be predicted under various conditions was investigated, and the results are reported.

A method which is capable of predicting the effect of the chemical substance t under various conditions was investigated, and the results are reported.

症例は18歳女性. 主訴は失神. 家族歴は兄が18歳で突然死. 現病歴は朝通学中の電車内で立位時に失神し, 次の駅で意識回復し当科に救急搬送となった. 来院時は意識清明. 心電図上, QT間隔は正常だが連結期の短い同形の心室性期外収縮より開始する非持続性多形性心室頻拍の頻発を認めた. 心臓超音波では軽度左室拡大のみで器質的心疾患は認めなかった. 発作時も含めQT延長はなく運動負荷によるQT延長, 多形性心室頻拍も認めなかった. カテコラミン負荷で増悪なく, カテコラミン誘発性多形性心室頻拍およびQT延長症候群は否定的と考えた. ピルジカイニド負荷で4連の多形性心室頻拍を認めたがベラパミル投与で抑制された. 遺伝子解析ではQT延長症候群, カテコラミン誘発性多形性心室頻拍, Brugada症候群に関連する遺伝子変異は陰性であった. short-coupled variant of torsade de pointesを最も疑い, 家族歴も考慮しICD植え込みを施行後ベラパミルの内服を開始し退院となった. その後は, ICDが作動することなく経過している.
