Blister beetles produce cantharidin, which is toxic to people and animals. Cantharidin has been believed to be an aphrodisiac and an abortifacient based on its tendency to cause marked irritation to the genitourinary system leading to priapism in men and pelvic congestion in women for many years. Cantharidin was used by oriental traditional medicine for more than 2000 years. Typical signs related to cantharidin ingestion are gastrointestinal tract and urinary tract irritation, endotoxemia, shock and myocardial dysfunction. Cantharidin is a severe irritant to epithelial linings (gastrointestinal tract, urinary tract, and skin) and develop systemic inflammatory response syndrome. We report a case of corrosive esophagogastritis and acute renal failure by ingestion of cantharidin.

Hydrofluoric acid (HF), one of the strongest inorganic acids, is used mainly for industrial purpose. Hydrofluoric acid injuries has a potential for both systemic as well as severe local tissue destruction. One of the most serious consequences of severe exposure to HF by any route is marked lowering of serum calcium (hypocalcemia) and other metabolic changes, such as hypomagnesemia and which may result in a fatal outcome if not recognized and treated. promptly cardiotoxicity is not well known except arrhythmias, which are a primary cause of death. We report a case of myopericarditis by ingestion of hydrofluoric acid.

Background: Trauma-induced deaths can be prevented by implementation of trauma system during prehospital phases and in-hospital phases. To reduce the preventable death rate (PDR), it is essential to improve the treatment strategy during the prehospital phases and the in-hospital phases. This study was designed to compares the prehospital death and emergency department (ED) death in a city before and after implementation of trauma system. Method: We evaluated the prehospital and ED data of 106 trauma patients who had died in 1991 and 2001. Trauma deaths were reviewed and the preventability of those deaths was judged by three professional panels according to appropriateness of diagnosis and treatment in prehospital phases and in-hospital phases. Deaths were classified as preventable and nonpreventable. We compared the preventable death of 1991 with those of 2001. Result: Trauma patients were 993 in 1991 and 3,094 in 2001. Trauma-induced deaths were 60 in 1991 and 46 in 2001. The death rate decreased from 6% in 1991 to 1.5% in 2001 (p<0.001). Death rate by traffic accident decreased from 90% (54/60) in 1991 to 67% (31/46) in 2001 (p<0.001). The PDR decreased from 40% (24/60) in 1991 to 13% (6/46) in 2001 (p<0.001). The time elapsed from the scene of accident to ED arrival decreased from 111 minutes in 1991 to 53 minutes in 2001 (p<0.001). There was no significant difference in Injury Severity Score between 1991 and 2001 (p=0.283). Conclusion: The rate of preventable death decreased from 1991 to 2001. Implementation and improvement of the trauma system has positive effects on trauma-induced death rate, PDR and the time elapsed from the scene of accident to ED arrival.

레이저 추적 시스템은 레이저 지시부와 레이저 수신부로 구성되며, 시스템 성능 분석을 위해 최대 탐지 거리와 각도 정확도를 고려해야 한다. 본 논문은 탐지 거리와 추적 각도 정확도의 관계를 확인하고 최대 탐지 거리와 유효 탐지 거리를 구분하여 분석하는 방법을 제시한다. 탐지 거리 성능은 레이저 신호 세기, 검출기 수신 신호, 레이저 추적 시스템의 출력 신호를 고려하여 계산하였으며, 가우시안 잡음을 적용하여 SNR 변화에 따른 추적 각도 오차를 계산하였다. 전산모사와 실험을 통해 SNR과 추적 각도 표준편차의 관계를 확인하고 비교적 간단하게 추적 각도 정확도를 계산하는 수식을 제시하였다. 탐지거리 분석 결과와 실험 결과의 오차는 4.5 %이다. The laser tracking system consists of a laser indicator and a laser receiver. For system performance analysis, the maximum detection distance and angle accuracy should be considered. In this paper, the detection range and tracking error of the laser tracking system were theoretically analyze and experimentally verified. The tracking angle error according to the SNR change was calculated by applying Gaussian noise. Computational simulations and experiments were performed to confirm the relationship between SNR and the standard deviation of the tracking angle. A relatively simple formula for calculating the tracking angle accuracy is presented. The error between the detection range analysis result and the experiment result is 4.5%.

The purpose of this study is to analyze the effects of transportation via Emergency Medical Service Information Center in a ski or snowboard injured patients. We evaluated 233 patients with ski or snowboard injuries who transported to emergency department from Nov. 2002 to Feb. 2003 via Emergency Medical Service Information Center or not. Among the patients, 66 patients were transported via Emergency Medical Service Information Center(group 1) and 167 patients were transported without using the information center(group 2). Transportation time and time for treatment of group 1 were shorter than that of group 2. Transportation time after injury were 119±92 minutes in group 1, 128±82 minutes in group 2. Treatment time after arrival of emergency department were 116±54 minutes in group 1, 126±75 minutes in group 2. Our results show that transportation after winter sports injury via Emergency Medical Service Information Center is effective for transportation and treatment.
