BACKGROUND: In 2015, South Korea experienced an outbreak of Middle East respiratory syndrome (MERS), and our hospital experienced a nosocomial MERS infection. We performed a comprehensive analysis to identify the MERS transmission route and the ability of our routine infection-prevention policy to control this outbreak. METHODS: This is a case-cohort study of retrospectively analysed data from medical charts, closed-circuit television, personal interviews and a national database. We analysed dat

INTRODUCTION: The aim of this study was to investigate the clinical efficacy and safety of laparoscopic appendectomy (LA) during pregnancy by comparing the operative and obstetric outcomes of patients who during pregnancy underwent LA performed by an expert gynaecologic laparoscopist (LA group) with those patients who underwent an open appendectomy (OA) by a general surgeon (OA group). MATERIALS AND METHODS: In this retrospective study, we evaluated all patients consecutively who had undergone a

INTRODUCTION: Following a chemical, biological, radiation and nuclear (CBRN) incident, prompt establishment of an advanced airway is required for patients with respiratory failure within the warm zone, while wearing personal protective equipment (PPE). Previous studies reported that intubation attempts were prolonged, and incidence of esophageal intubation was increased with conventional Macintosh laryngoscope (McL), while wearing CBRN-PPE. Pentax-AWS (AWS), a recently introduced portable video

(HP), mononuclear cell (lymphocytes and plasma cells), and neutrophil scores were assessed on the basis of the updated Sydney system (USS), which is widely used for histological grading. The aim of this study was to assess the relationships between gastric histological features and lipid profile levels. This study included 15,322 males and 5929 females who underwent a health checkup and gastric biopsy at the Kangbuk Samsung Medical Center (KBSMC). We analyzed whether the HP, mononuclear cell, an

Aim The two-thumb encircling (TTE) technique often results in suboptimal cardiac compression and does not meet the requirements of current resuscitation guidelines. We compared this technique with the vertical two-thumb (VTT) technique, our novel modification of the TTE technique. Methods This was a prospective randomised crossover simulation study of out-of-hospital infant cardiopulmonary resuscitation (CPR). Participants who had completed a basic life support course performed 10 cycles of card

The utilization of cosmetic raw materials for medicinal purposes in a microneedle patch containing hyaluronic acid (HA) and Lonicerae flos ethanol extract (LEE) has increased based on their eco-friendly characteristics. The moisturizing effects of this microneedle patch were assessed on the forearms of 20 female participants, and our results showed an increase between 29.60% and 88.54% in skin moisture content at the same time points relative to the untreated group. Apart from confirming the saf

MRI can reliably differentiate surgical conditions and several blood tests (WBC, proportion of neutrophils in the WBC, NLR, CRP, bilirubin) can help anticipate acute surgical condition among pregnant patients suspected to have acute appendicitis.

BACKGROUND: Different face mask designs can influence bag-valve-mask (BVM) ventilation performance during resuscitation. We compared a single-use, air-cushioned face mask (AM) with a reusable silicone face mask (SM) for quality of BVM ventilation on a manikin simulating cardiac arrest. METHODS: Thirty-two physicians were recruited, and a prospective, randomized, crossover observational study was conducted after an American Heart Association-accredited basic life support provider course and stand

Background A hyper-intense vessel sign on fluid attenuated inversion recovery magnetic resonance imaging (FHV) represents slow blood flow in the cerebral arteries. Purpose To investigate the relationship between the proximal FHV (pFHV) on initial magnetic resonance imaging (MRI) and the status of the culprit vessel (stenosis, obstruction) in hyper-acute strokes affecting the territory of the middle cerebral artery (MCA). Material and Methods The study participants consisted of 105 patients prese
