A comprehensive evaluation of efficacy of hyperbaric oxygen therapy in non-arteritic central retinal artery occlusion using enhanced depth imaging optical coherence tomography.

This study aimed to assess the efficacy of hyperbaric oxygen therapy (HBOT) in patients with central retinal artery occlusion (CRAO) by analyzing changes in visual acuity (VA) and enhanced depth imaging optical coherence tomography (EDI-OCT) parameters. A comparative retrospective study was conducted by reviewing the medical records of all HBO-treated RAO patients in our department and comparing them with matched RAO patients who did not receive HBO treatment. All patients treated with HBO received treatment within 7 days of the onset of visual symptoms.

A Crowd Disaster Study: The Itaewon Seoul Crush.

The recent Halloween crowd crush incident in Itaewon, Seoul, Korea, highlights a woeful inadequacy in our collective knowledge about crowd disasters. Underscored is a lack of detailed information on the causes of death and the injuries sustained. While traumatic asphyxiation has been widely implicated as the primary cause of death, the wider spectrum of injury patterns and their causative mechanisms remain poorly identified.

Efficacy and safety of ketamine alone and ketamine-dexmedetomidine combination for sedation for brain computed tomography in paediatric patients with head injuries: A retrospective study.

Objective: To compare the efficacy and safety of ketamine alone with those of ketamine-dexmedetomidine combination for sedation during brain CT in paediatric patients with head injuries.

Methods: We retrospectively analysed the data of paediatric patients who underwent sedation for brain CT at the ED. We included patients aged 6 months to 6 years with American Society of Anesthesiologists physical status I or II.

Analyzing willingness for extracorporeal cardiopulmonary resuscitation in refractory ventricular fibrillation.

Extracorporeal cardiopulmonary resuscitation (ECPR) for refractory ventricular fibrillation/ventricular tachycardia in out-of-hospital cardiac arrest has recently been recommended for selected patients with favorable prognostic features. We aimed to identify factors affecting the willingness of emergency physicians to implement extracorporeal cardiopulmonary resuscitation (ECPR). We conducted a factorial survey with nine experimental vignettes by combining three different scene time intervals and transportation time intervals.

Evaluation of class participation in non-face-to-face CPR training for medical students.

Background: Cardiopulmonary resuscitation (CPR) education requires that learners practice key skills to promote mastery. Our aim in this study was to evaluate differences in post-education performance and class participation during CPR training between face-to- face (FF) and non-face-to-face (NFF) learning formats.

Methods: This was a randomized controlled study of third-year medical students from two university hospital, allocated to either the FF or NFF format for CPR education.

Extremity Injuries during Sporting Activities According to Life Course: Focusing on Fractures.

Background: The increased participation in sports has led to an increased number of sports-related injuries. We aimed to identify the incidence of sports-related injuries by life course and the risk factors for sports-related extremity fractures.

Methods: We analyzed data of patients with sports-related extremity injuries from Emergency Department-based national injury surveillance systems, obtained from Jan 2013 to Dec 2016.

Unintended beneficial effects of COVID-19 on influenza-associated emergency department use in Korea.

Background: Non-pharmaceutical interventions, including hand hygiene, wearing masks, and cough etiquette, and public health measures such as social distancing, used to prevent the spread of coronavirus disease 2019 (COVID-19), could reduce the incidence rate of respiratory viral infections such as influenza. We evaluated the effect of COVID-19 on the incidence of influenza in Korea.

Methods: This retrospective study included all patients who visited five urban emergency departments (EDs) during the influenza epidemic seasons of 2017-18, 2018-19, and 2019-20.

Risk Factors for Intracranial Injury Caused by Falls at Home in Korea Using Data from the Emergency Department-based Injury In-depth Surveillance (2011-2018).

Background: Most unintentional injuries that occur at home are preventable. However, it may be difficult to sufficiently reduce the number of falls occurring at home by only identifying risk factors focused on specific age groups. Therefore, this study aimed to identify the risk factors (especially age and places where injuries occurred at home) for intracranial injury (ICI) caused by unintentional falls at home.

Changes to the Korean Disaster Medical Assistance System After Numerous Multi-casualty Incidents in 2014 and 2015.

Objective: A number of multiple-casualty incidents during 2014 and 2015 brought changes to Korea's disaster medical assistance system. We report these changes here.

Methods: Reports about these incidents, revisions to laws, and the government's revised medical disaster response guidelines were reviewed.

A study on the disaster medical response during the Mauna Ocean Resort gymnasium collapse.

Objective: To investigate and document the disaster medical response during the Gyeongju Mauna Ocean Resort gymnasium collapse on February 17, 2014.

Methods: Official records of each institution were verified to select the study population. All the medical records and emergency medical service run sheets were reviewed by an emergency physician.

Minor complications after mandibular third molar surgery: type, incidence, and possible prevention.

Purpose: The aim of this prospective study was to ascertain the incidence of minor complications after mandibular third molar surgery and to predict the risk of skin ecchymosis or mucosa petechiae related to the usage of an absorbable gelatin sponge.

Patients And Methods: One hundred and four patients subjected to surgical extraction of horizontally impacted lower third molars were selected and investigated by means of questionnaires and clinical examinations. The independent sample t test was used for numeric variables.

Terrorism in South Korea.

South Korea has experienced > 30 suspected terrorism-related events since 1958, including attacks against South Korean citizens in foreign countries. The most common types of terrorism used have included bombings, shootings, hijackings, and kidnappings. Prior to 1990, North Korea was responsible for almost all terrorism-related events inside of South Korea, including multiple assassination attempts on its presidents, regular kidnappings of South Korean fisherman, and several high-profile bombings.
