Hydrogen sulfide is a by-product of decayed organic material and is ubiquitously found as an ingredient of manufacturing reagents or as an undesirable by-product of the manufacturing or industrial processing. Hydrogen sulfide is a chemical asphyxiant and interferes with cytochrome oxidase and aerobic metabolism. It has thus been deemed an important cause of work-related sudden death. This gas is particularly insidious due to the unpredictability of its presence and concentration and its neurotoxicity at relatively low concentrations, causing olfactory nerve paralysis and loss of the warning odor. Here, we report two cases of comatose patients presenting after accidental exposure to hydrogen sulfide gas.

Purpose: Sleep apnea (SA) is a risk factor for coronary artery disease (CAD), and SA and CAD increase the incidence of sudden cardiac arrest (SCA). This study aimed to investigate the effect of SA on the incidence of SCA and explore the effect of varying de grees of SA with or without CAD on the incidence of SCA. Materials and Methods: This prospective multi-center, case-control study was performed using the phase II Cardiac Arrest Pursuit Trial with Unique Registry and Epidemiologic Surveillance (CAPTURES-II) database for SCA cases and community-based controls in Korea. The matching ratio of cases to controls was 1:1, and they were randomly matched within demographics, including age, sex, and residence. The primary variable was a history of SA, and the second variable was a history of CAD. We conducted a conditional logistic regression analysis to estimate the effect of SA and CAD on the SCA risk, and an interaction analysis between SA and CAD. Results: SA was associated with an increased risk of SCA [adjusted odds ratio (AOR) (95% confidence interval, CI): 1.54 (1.16–2.03)], and CAD was associated with an increased risk of SCA [AOR (95% CI): 3.94 (2.50–6.18)]. SA was a risk factor for SCA in patients without CAD [AOR (95% CI): 1.62 (1.21–2.17)], but not in patients with CAD [AOR (95% CI): 0.56 (0.20–1.53)]. Conclusion: In the general population, SA is risk factor for SCA only in patients without CAD. Early medical intervention for SA, especially in populations without pre-existing CAD, may reduce the SCA risk. ClinicalTrials.gov (NCT03700203)

소형화되는 센서 기술 및 무선 통신 기술의 발달로 인한 사물인터넷을 기반 원격헬스케어를 위한 다양한 연구들이 진행되고 있다. 특히, 원격헬스케어 서비스는 환자의 민감 정보인 건강기록을 다루기 때문에 보안 및 프라이버시에 대한 요구사항이 다른 응용보다 더 중요하게 고려되고 있다. 이를 위해 최근에 Alzahrani 등은 원격헬스케어를 위한 경량화된 환자-헬스케어 인증 프로토콜을 제안하였다. 하지만, 본 논문에서는 Alzahrani 등의 프로토콜이 비추적성을 제시하지 못하는 문제를 Canetti-Krawczyk 모델에 기반한 BAN 로직 분석을 통해 증명한다. 또한, 이들 프로토콜에 존재하는 문제를 해결하기 위한 해결 방안에 대해 간략한 개요를 제시한다.

A thyroid cartilage fracture is a rare entity and can be overlooked easily. Such cases are difficult to diagnose, and assessment and treatment guidelines are difficult to determine. CT of the neck region may be useful when acute airway intervention is not required or when more information regarding the neck`s anatomy is required for management decisions. We describe a case of a thyroid cartilage fracture with displacement. In the emergency department (ED), neck CT and fiberoptic nasopharyngoscopy were used to assess the status of the patient`s (a male) vocal chords immediately. He remained unable to phonate continuously. After an immediate assessment, we decided to use steroid and conservative therapy. The patient had a good recovery and was without symptoms one month after injury. There is no question that early surgical repair of neck injuries affords the best results for airway and voice patency in most cases however, we suspect that surgical repair is not needed in all cases. Early recognition and an accurate therapy plan for a thyroid fracture with displacement are essential. Therefore, the emergency physician`s immediate and careful decision based on endoscopy and neck CT is important for the patient`s long-term recovery. (J Korean Soc Traumatol 2010;23:53-55)

Several cases of ruptured pregnant uterine horn have been documented. However, there have been few reported cases of ectopic tubal pregnancy in a unicornuate with rudimentary horn. So we report this case with a brief review literature.

Fenazaquin (4-[[4 (1,1-dimethylethyl) pheynyl]ethoxy]quinazoline)is an insecticide that inhibits NADH ubiquinone oxidoreductase of the mitochondria, which is also known as complex I. An 83 year old female was brought to our emergency department (ED) having been found collapsed and unconscious at home by her family. She had ingested up to 100 ml from a bottle of 20% fenazaquin solution. In the ED,she showed severe persistent lactic acidosis despite a seemingly stable hemodynamic condition. Despite intensive supportive management, including positive pressure ventilation,packed red cell transfusion, hemodialysis, and intravenous N-acetylcysteine administration, the lactic acidosis did not respond. To our knowledge, this is the first report of fenazaquin poisoning in humans. No antidote for fenazaquin is known. In this case report, we discuss clinical characteristics and possible pathophysiologic mechanism of fenazaquin poisoning with a literature review.

Purpose:The principle of prehospital transport is that the patient should be transported to the nearest hospital that is suitable for the severity of the illness. Therefore, out-of-jurisdiction transport is improper. The purpose of this study was to understand the present situation and evaluate the appropriateness of out-of-jurisdiction prehospital transport by the 119 rescue group. Methods: Between January and December 2009 we enrolled patients who were transported to the Gwangju Regional Emergency Medical Center by the 119 rescue group, which belongs to Jeolla province. The appropriateness of out-of-jurisdiction transport was based on the transport chart and medical record of the 119 rescue group and categorized into three groups. Results:The total number of patients transported was 440:78 (17.7%) were appropriate; 329 (74.8%) were inappropriate;33 (7.5%) patients were very inappropriate. Of the 440,156 (35.5%) were emergency cases, 147 (33.4%) were sub-emergency cases, and 137 (31.1%) were non-emergency cases. Comparing these data with the triage by the 119 rescue group, the kappa value was 0.368 (p<0.001). The patients or their guardians selected the hospital to which the patient was be transported in 382 (86.8%) cases. The actual transport distance was 40.0 km (range: 26.0 to 50.0) and was significantly longer than the nearest distance to a local emergency center which was 10.0 km (4.0 to 18.0) (p<0.001). Conclusion: Inappropriate out-of-jurisdiction transporting of patients is done frequently. Therefore, guidelines for prehospital transportation according to the triage is necessary. Additionally, the medical director and emergency medicine information center could play a role in selecting a hospital. A fee or a fine of transporters who do not observe the guidelines might limit the proportion of inappropriate transport cases.
