The survival rate of commotio cordis is low, and there is often associated neurological disability if return of spontaneous circulation (ROSC) can be achieved. We report a case of commotio cordis treated with therapeutic hypothermia (TH) that demonstrated a favorable outcome. A 16-year-old female was transferred to our emergency department (ED) for collapse after being struck in the chest with a dodgeball. She has no history of heart problems. She was brought to our ED with pulseless ventricular tachycardia (VT), and ROSC was achieved with defibrillation. She was comatose at our ED and was treated with TH at a target temperature of 33degrees C for 24 hours. After transfer to the intensive care unit, pulseless VT occurred, and defibrillation was performed twice. She recovered to baseline neurologic status with the exception of some memory difficulties.

PURPOSE: This study was conducted to assess the satisfaction, and factors influencing the satisfaction, of patients and guardians with the internal environment and safety of ambulances in Korea. METHODS: Participants were patients and guardians who were transported by public emergency medical service ambulance to an emergency medical center in June 2015. Data were collected using self-administered questionnaires. The degree of satisfaction with the ambulance was categorized as satisfaction (Likert scale 4 or 5) or dissatisfaction (Likert scale 1 or 2). The questionnaires comprised 3 categories: 1) demographics, 2) internal environment (space, light, temperature, humidity, soundproof, and odor), and 3) safety (vibration, leaning of body, and falling objects). RESULTS: Among 84 cases, 80.5% of patients and 83.7% of guardians gave positive responses regarding general satisfaction with the internal environment of the ambulance, but these percentages were lower regarding adequacy of space and light. Four factors had a statistically significantly influence on the degree of satisfaction: 1) sex of guardian regarding adequacy of space, 2) number of guardians regarding general satisfaction, 3) severity of patient regarding guardian's satisfaction with space, 4) diagnosis of patient (trauma vs non-trauma) regarding vibration during transport (all p<0.05). CONCLUSION: Overall, patients and guardians were satisfied with the internal environment and safety of ambulances except for adequacy of space and light.

Sulfoxaflor is the first insecticide belonging to the sulfoximine class and is efficient against sap-feeding insects that are resistant to other insecticides. Sulfoxaflor acts as a neurotoxin to the central nervous system of insects compared with very low toxicity to mammalian. We report on a case of a 67-year-old male who ingested insecticide and received conservative treatment for mild metabolic acidosis and gastrointestinal symptoms.

Breast cancer is the second leading cancer for Korean women and its incidence rate has been increasing annually. If early diagnosis were implemented with epidemiologic data, the women could easily assess breast cancer risk using internet. National Cancer Institute in the United States has released a Web-based Breast Cancer Risk Assessment Tool based on Gail model. However, it is inapplicable directly to Korean women since breast cancer risk is dependent on race. Also, it shows low accuracy (58%-59%). In this study, breast cancer discrimination models for Korean women are developed using only epidemiological case-control data (n = 4,574). The models are configured by different classification techniques: support vector machine, artificial neural network, and Bayesian network. A 1,000-time repeated random sub-sampling validation is performed for diverse parameter conditions, respectively. The performance is evaluated and compared as an area under the receiver operating characteristic curve (AUC). According to age group and classification techniques, AUC, accuracy, sensitivity, specificity, and calculation time of all models were calculated and compared. Although the support vector machine took the longest calculation time, the highest classification performance has been achieved in the case of women older than 50 yr (AUC = 64%). The proposed model is dependent on demographic characteristics, reproductive factors, and lifestyle habits without using any clinical or genetic test. It is expected that the model could be implemented as a web-based discrimination tool for breast cancer. This tool can encourage potential breast cancer prone women to go the hospital for diagnostic tests.

Considerable evidence has been published since the 2020 Korean Cardiopulmonary Resuscitation Guidelines were reported. The International Liaison Committee on Resuscitation (ILCOR) also publishes the Consensus on CPR and Emergency Cardiovascular Care Science with Treatment Recommendations (CoSTR) summary annually. This review provides expert opinions by reviewing the recent evidence on CPR and ILCOR treatment recommendations. The authors reviewed the CoSTR summary published by ILCOR in 2021 and 2022. PICO (population, intervention, comparator, outcome) questions for each topic were reviewed using a systemic or scoping review methodology. Two experts were appointed for each question and reviewed the topic independently. Topics suggested by the reviewers for revision or additional description of the guidelines were discussed at a consensus conference. Forty-three questions were reviewed, including 15 on basic life support, seven on advanced life support, two on pediatric life support, 11 on neonatal life support, six on education and teams, one on first aid, and one related to coronavirus disease 2019 (COVID-19). Finally, the current Korean CPR Guideline was maintained for 28 questions, and expert opinions were suggested for 15 questions.
