Commotio cordis is induction of sudden cardiac arrest and ventricular fibrillation (VF) by chest blunt trauma and nonpenetrating injury without damage to the rib, sternum, and heart in a person without underlying cardiovascular disease. Commotio cordis has been rarely reported worldwide, and it is particularly rare in the case of traffic accident (TA). We experienced a case of commotio cordis in a healthy 20-year-old man who was involved in a TA. The patient had no other signs of trauma except blunt chest trauma, and the initial electrocardiography (ECG) rhythm checked by the emergency medical technician (EMT) team was VF. They performed defibrillation and cardiopulmonary resuscitation (CPR) during transfer. CPR including defibrillation was performed because VF continued upon arrival at the emergency department, and therapeutic hypothermia (THT) was performed because glasgow coma scale (GCS) score was 3 after return of spontaneous circulation (ROSC). The patient's mental status became alert after performance of THT and cerebral performance category (CPC) score was 1 without neurological symptoms at the time of discharge. In trauma patients who may be have blunt chest trauma, including TA, emergency medical service providers must perform continuous monitoring with commotio cordis in mind, and perform defibrillation and CPR immediately if VF arises. With training in basic CPR and a supply of automated external defibrillators (AED) for application to trauma patients, the survival rate of commotio cordis patients can be increased.

Purpose: The study aimed to develop an objectified Korean Triage and Acuity Scale (OTAS) that can objectively and quickly classify severity, as well as a simple age-adjusted OTAS (S-OTAS) that reflects age and evaluate its usefulness. Materials and Methods: A retrospective analysis was performed of all adult patients who had visited the emergency department at three teaching hospitals. Sex, systolic blood pressure, diastolic blood pressure, pulse rate, respiratory rate, body temperature, O 2 saturation, and consciousness level were collected from medical records. The OTAS was developed with objective criterion and minimal OTAS level, and S-OTAS was developed by adding the age variable. For usefulness evaluation, the 30-day mortality, the rates of computed tomography scan and emergency procedures were compared between Korean Triage and Acuity Scale (KTAS) and OTAS. Results: A total of 44402 patients were analyzed. For 30-day mortality, S-OTAS showed a higher area under the curve (AUC) compared to KTAS (0.751 vs. 0.812 for KTAS and S-OTAS, respectively, p<0.001). Regarding the rates of emergency procedures, AUC was significantly higher in S-OTAS, compared to KTAS (0.807 vs. 0.830, for KTAS and S-OTAS, respectively, p=0.013). Conclusion S-OTAS showed comparative usefulness for adult patients visiting the emergency department as a triage tool compared to KTAS.

BACKGROUND: Acquired perforating dermatosis (APD) is histopathologically characterized by transepidermal elimination of materials from the upper dermis. APD can be divided into four diseases: Kyrle's disease, perforating folliculitis, elastosis perforans serpiginosa, and reactive perforating collagenosis. APD is usually associated with systemic diseases, especially diabetes mellitus or chronic renal failure. So far, there have only been a few Korean studies of APD, which have a limited number of patients. OBJECTIVE: The aim of this study is to evaluate the clinical and histopathologic characteristics of 30 cases of APD and to examine the association with systemic diseases. METHODS: We retrospectively reviewed the medical records and biopsy specimens of 30 patients who were diagnosed with APD. RESULTS: The mean age was 55.5 years, and the average duration of the lesion was 7.8 months. The lower extremities (73.3%) were the most frequently occurring sites of the lesion. Twenty-five patients (83.3%) had pruritus, and Koebner's phenomenon was present in 11 patients. Patients of 63.3% had at least one systemic disease. Diabetes mellitus (n=17, 56.7%) and chronic renal failure (n=10, 33.3%) were the most commonly associated conditions. Most patients received topical steroids (93.3%) and antihistamines (80.0%). The most common histopathologic type was reactive perforating collagenosis (n=23, 73.3%). CONCLUSION: In this study, most patients had a systemic association to the diseases. Therefore, we suggest that further evaluation is necessary for patients who present with APD. This includes reviewing patient's comprehensive past medical history, clinical exam, and additional diagnostic testing to check for the possibility of associated systemic diseases.

PURPOSE: Many patients who are acutely poisoned with organophosphorus pesticides have co-ingested alcohol. The purpose of this study was to identify the factors that influence mortality in organophosphate intoxication and the differences between alcohol coingested patients and non-coingested patients, looking at vital signs, length of admission, cholinesterase activity, complications, and mortality. METHODS: All patients visiting one Emergency Department (ED) with organophosphate intoxication between January 2000 and December 2012 were reviewed retrospectively. The patients were divided into two groups, alcohol coingested group and non-coingested group. RESULTS: During the study period, 136 patients (alcohol coingested group, 95 patients; non-coingested group, 41 patients) presented to the ED with organophosphate intoxication. Seventy-one alcohol coingested patients (74.1%) vs. 16 non-coingested patients (39.0%) received endotracheal intubation, with results of the analysis showing a clear distinction between the two groups (p=0.001). Twenty-three alcohol coingested patients (24.2%) vs. 1 non-coingested patient (2.4%) required inotropics, indicating a significant gap (p=0.002). Twenty-eight alcohol coingested patients (29.5%) vs. 2 non-coingested patients (4.9%) died, with results of the analysis showing a clear distinction between the two groups (p=0.002). CONCLUSION: In cases of organophosphate intoxication, alcohol coingested patients tended to receive endotracheal intubation, went into shock, developed central nervous system complications, and more died.
