<b><i>Objective:</i></b> Until now, cutoff values of low skeletal muscle mass using computed tomography (CT) were driven by optimal stratification to predict mortality in cancer patients. The aim of the present study was to investigate the simple, age-specific, cutoff value of low skeletal muscle mass by CT in healthy adults. <b><i>Design:</i></b> This is a retrospective, observational, single-center study. <b><i>Setting:</i></

Rapid diagnosis and timely treatment improves the outcome in patients with ischemic stroke, but a rapid and sensitive blood test for ischemic stroke does not exist. This study tested whether a panel of biomarkers might be useful in the diagnosis of acute ischemic stroke. Consecutive patients with suspected stroke presenting to the emergency department of a university hospital in Korea were enrolled. Plasma specimens were assayed for brain natriuretic peptide, D-dimer, matrix metalloproteinase-9,

BACKGROUND/AIMS: Muscle mass depletion has been suggested to predict morbidity and mortality in various diseases. However, it is not well known whether muscle mass depletion is associated with poor outcome in sepsis. We hypothesized that muscle mass depletion is associated with poor outcome in sepsis. METHODS: Retrospective observational study was conducted in an emergency department during a 9-year period. Medical records of 627 patients with sepsis were reviewed. We divided the patients into 2

The prevalence and prognostic value of overt disseminated intravascular coagulation (DIC) in patients with septic shock presenting to emergency departments (EDs) is poorly understood, particularly following the release of a new definition of septic shock. The purpose of this study was to investigate the prevalence and prognostic value of DIC in septic shock. Methods: We performed retrospective review of 391 consecutive patients with septic shock admitting to the ED of tertiary care, university-a

Tension pneumocephalus may follow a cerebrospinal fluid (CSF) leak communicating with extensive extradural air. However, it rarely occurs after diagnostic lumbar puncture, and its treatment and pathophysiology are uncertain. Tension pneumocephalus can develop even after diagnostic lumbar puncture in a special condition. This extremely rare condition and underlying pathophysiology will be presented and discussed. The authors report the case of a 44-year-old man with a basal skull fracture accompa

OBJECTIVE: This study aimed to describe the relationship between sex and survival of patients with out-of-hospital cardiac arrest (OHCA) and further investigate the potential impact of female reproductive hormones on survival outcomes, by stratifying the patients into two age groups. METHODS: This retrospective, national population-based observational, case-control study, included Korean OHCA data from January 1, 2009, to December 31, 2016. We used multiple logistic regression with propensity sc

There are only three species of poisonous snakes in Korea. Deaths from poisonous snakebites are rare in Korea, but the World Health Organization estimates that as many as 30,000 to 40,000 death occur following venomous snakebites. The most important factor for determining a prognosis for a victim of a venomous snakebite is the grade of envenomation, because the grade of envenomation is highly correlated with severe complications such as disseminated intravascular coagulopathy, a bleeding tendenc

OBJECTIVE: This study investigated the characteristics and survival rates of patients with unintentional severe trauma who visited a regional trauma center (TC) or a non-TC. METHODS: This retrospective, national, population-based, observational, case-control study included patients with abnormal Revised Trauma Score from January 2018 to December 2018. We divided hospitals into two types, TC and non-TC, and compared several variables, including in-hospital mortality. Propensity score matching was

P u r p o s e: Fever is the single most common problem in children visiting the emergency department. Fever is treated with a variety of methods, including the recommended combination of tepid massage, and antipyretics. We compared the effects of antipyretics and tepid massage for the management of febrile children. M e t h o d s: We conducted a prospective, randomized, controlled study to assess 49 children who visited to the ED, Kyung Hee Medical Center, with complaints of fever. Ages ranged f

Purpose: We evaluated the differences between the clinical characteristics, procedure and results of real life cardiopulmonary resuscitation versus how CPR is portrayed in Korean medical dramas. Methods: We watched 58 episodes of Korean television medical dramas including <Surgeon, Bong Dalhee>, <New heart> and <General hospital>, broadcast during the period 2007 to 2010. We identified all occurrences of CPR in each episode and collected the fictional patients’ age, sex, location,presumed cause

Background: The purpose of this study was to identify the degree of home isolation and to determine what is needed for an effective home isolation through experience with home isolation that has been found to be in close contact persons with MERS-confirmed patient. Methods: We conducted a questionnaire survey of employees at a university hospital in Seoul, Korea, which were classified as close contact with the MERS patient who visited the emergency room in June 2015. The questionnaire items were
