Nicolau syndrome is a rare adverse reaction at the site of an intramuscular injection, and is characterized by severe pain immediately after the injection and rapid development of distinct skin lesions. As this syndrome is rare, it may be overlooked at the early clinical phase and subsequently, clinical outcomes may be worse due to delay in treatment. We report on a female who developed Nicolau syndrome following intramuscular diclofenac injection, which required surgical reconstruction. Understanding the characteristics of Nicolau syndrome and careful surveillance for relevant clinical features may help physicians to more quickly diagnose and treat this condition.

Purpose: No previous study has assessed elderly pedestrian traffic accidents based on a nationwide database. This study aimed to help primary physicians who examine patients in emergency departments to determine and make prompt and accurate treatment decisions. Methods: This study used data from the Emergency Department-based Injury Indepth Surveillance from 2013 to 2017, managed by the Korea Centers for Disease Control and Prevention. Pedestrians aged ${\geq}65years$ were included, and using multivariate logistic regression multiple factors were analyzed to determine their relationship with injury severity. Results: Of 227,695 subjects, 6,498 were included, of whom 2,065 (31.8%) were severely injured. There were more female than male patients in all severity groups. Most accidents occurred in the afternoon and on general roads. In the multivariate analysis, the odds ratio (OR) of injury severity for male pedestrians was 1.165 (95% confidence interval: 1.034-1.313, p=0.012). Older age of patients and the use of ambulances were associated with greater injury severity. The accident time affected the degree of injury severity; i.e., compared to dawn, injury severity increased in the morning (OR: 1.246, p=0.047) and decreased at night (OR: 0.678, p<0.001). A significant difference was noted in the correlation between the type of vehicle causing the accident and the accident severity; i.e., motorcycle accidents had lower severity than bicycle accidents (OR: 0.582, p=0.047). Conclusions: Injury severity was correlated with sex, age, transportation to the ED, TA onset time, and type of vehicle. The study results suggest that injury severity may be positively reflected in initial assessments and overall integrated treatments by physicians and in the related policies.

Purpose: Gaining vascular access is difficult and time-consuming in critically ill children, so nowdays, in many countries, intraosseous vascular access is frequently used for rapid vascular access in critically ill children. Its pharmacokinetics is close to that of the peripheral intravenous route, but its infusion flow rate is faster. The purpose of this study was to determine how widely the intraosseous infusion technique was being used in Korean emergency departments. Methods: We telephoned forty-two (42) randomly selected university-affiliated hospitals. We asked physicians if they use the intraosseous infusion technique. Responders were emergency and pediatric residents and emergency faculty. If they responded that they were not using the intraosseous infusion technique, we asked the reason. Also, we asked about their experiences with the intraosseous infusion technique. Results: Forty-two (42) hospitals were enrolled in this study. No hospital used the intraosseous infusion technique on a regular basis. However, 8 hospitals used the intraosseous infusion technique occasionally. None of the responders had experience with the intraosseous infusion technique. Conclusion: The intraosseous infusion technique is currently underrepresented at emergency departments in Korea.

Because of the ready availability of aspirin, salicylate poisoning remains a common problem in many countries. Another potential source of salicylate poisoning is medicated oil containing methyl salicylate (oil of wintergreen). Methyl salicylate poses a much greater safety threat than aspirin tablets because of its liquid, concentrated form and high lipid solubility. Because of this danger, the toxic potential of medicated oil containing methyl salicylate should be fully appreciated both by physicians and by the general public. We encountered two cases of salicylate poisoning resulting from accidental ingestion of Chinese medicated oil. We report these cases along with a review of the literature.

The objective is to review a case of pneumoparotitis and to discuss how knowledge of this unique presentation is important when making differential diagnoses in emergency medicine. A patient with recurrent subcutaneous emphysema of the head and neck is reviewed. Stenson's duct demonstrated purulent discharge. Physical examination revealed palpable crepitance of the head and neck. Fiberoptic laryngoscopy and barium esophagram were normal. Computed tomography demonstrated left pneumoparotitis and subcutaneous emphysema from the scalp to the clavicles. This is an unusual presentation of pneumoparotitis and malingering. Emergency physicians should be aware of pneumoparotitis and its presentation when creating a differential diagnosis for pneumomediastinum, which includes more life-threatening diagnoses such as airway or esophageal injuries.

Background: According to the reports of the World Health Organization 20% of world population suffer from pain and 33% of them suffer to some extent that they cannot live independently. Methods: This is a cross-sectional study which was conducted in the emergency department (ED) of Valiasr Hospital of Arak, Iran, in order to determine the causes of delay in prescription of analgesics and to construct a model for prediction of circumstances that aggravate oligoanalgesia. Data were collected during a period of 7 days. Results: Totally, 952 patients participated in this study. In order to reduce their pain intensity, 392 patients (42%) were treated. Physicians and nurses recorded the intensity of pain for 66.3% and 41.37% of patients, respectively. The mean (SD) of pain intensity according to visual analogue scale (VAS) was 8.7 (1.5) which reached to 4.4 (2.3) thirty minutes after analgesics prescription. Median and mean (SD) of delay time in injection of analgesics after the physician's order were 60.0 and 45.6 (63.35) minutes, respectively. The linear regression model suggested that when the attending physician was male or intern and patient was from rural areas the delay was longer. Conclusions: We propose further studies about analgesics administration based on medical guidelines in the shortest possible time and also to train physicians and nurses about pain assessment methods and analgesic prescription.

Foreign body (FB) ingestion of children is a common pediatric emergency requiring medical attention. Pediatric emergency physicians and gastroenterologists often encounter nervous and distressed situations, because of children presenting with this condition in the common clinical practice. When determining the appropriate timing and indications for intervention, physicians should consider multiple patient- and FB-related factors. The utilization of a flexible endoscopy is considered safe and effective to use in these cases, with a high success rate, for the effective extraction of FBs from the gastrointestinal tract of a child. Additionally, a Foley catheter and a magnet-attached Levin tube have been used for decades in the case of FB removal. Although their use has decreased significantly in recent times, these instruments continue to be used for several indications. Using a Foley catheter for this purpose does not require special training and does not necessarily require sedation of the patient or fluoroscopy, which serve as advantages of utilizing this method for foreign object retrieval. An ingested magnet or iron-containing FB can be retrieved using a magnet-attached tube, and can be effective to retrieve an object from any section of the upper gastrointestinal tract that can be reached. Simple and inexpensive devices such as Foley catheters and magnetattached tubes can be used in emergencies such as with the esophageal impaction of disk batteries if endoscopy cannot be performed immediately (e.g., in rural areas and/or in patients presenting at midnight in a facility, especially in those without access to endoscopes or emergency services, or in any situation that warrants urgent removal of a foreign object).

Purpose: The aim of this study was to evaluate the usefulness of video communication with medical staff located at a remote location, through a communication application connected to a long term evolution (LTE) mobile communication network in a moving ambulance. Methods: In this study, we recruited patients who were transferred by mobile intensive care unit ambulance from one hospital to another. In the moving ambulance, the information of the patient was transferred to a physician using the application in real time. Recorded video files were evaluated by emergency physicians with experience in video direct medical control. Results: A total of 18 patients were evaluated, and the average score was 5.9 out of a possible 9. It was expected that applying the use of the technology to actual clinical sites would enable the sites to provide assistance. Conclusion: In this study, we confirmed the possibility of benefiting from the clinical field when using the video-audio communication application which is connected to the remote location in real time through the current LTE mobile communication network in the ambulance.

Purpose: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an emergency procedure and extremely time-dependent, and the proficiency of the physician is important. Due to a lack of REBOA education programs in Republic of Korea, few physicians have been trained in the procedure. In this study, we examined how REBOA education affects clinical outcomes in a single center. Methods: A retrospective study conducted from February 2017 to June 2020 at a regional trauma center. We collected data of patients who underwent REBOA and analyzed the factors that influenced the outcome. The patients were divided into the educated and non-educated groups (based on REBOA training received by their physicians), and the success and failure groups. Results: A total of 24 patients underwent REBOA during the study. There were eight patients in the success group and 16 patients in the failure group. There are no significant differences between the educated and non-educated groups in sex, age, ISS, shock, injury-to-REBOA time, injury mechanism, injury sites, arrest, access site, type of catheter, type of REBOA, target Zone, mortality, and the result of REBOA. The non-educated group had a higher risk for failure compared to the educated group in multivariate analysis (odds ratio [OR] 154.64, 95% confidence interval [CI] 1.11-22.60). Conclusions: Failure in REBOA is harmful to patients. The risk of failure is increased in the non-educated group. Physicians working in the trauma center or emergency department need to complete the REBOA education program.

A physician has to do his best for the better treatment of his patiensts. But, if a physician cannot remedy his patients because of the lack of hospital facilities, the lack of medical knowledge and etc., the physician must transfer his patients to another suitable hospital immediately. This is called the duty of interhospital transfer of patients. The necessity of interhospital transfer of patients is primarily ocurred in emergency medical care situations. The Supreme Court Decision 2010DO7070 delivered on April 29, 2010 is one of the important decisions related to the duty of interhospital transfer of patients. The Supreme Court ruled that there were the physician's medical malpractice and the causation between the physician's medical malpractice and the death of patient, as the physician has left the patient without due observations for 1 hour and 30 minutes after the caesarean operation inspite of mass bleeding during the operation, and has transferred the patient to another suitable hospital later. And the Supreme Court ruled that the transferring physician has to explain the situation of the patient in detail to the physician being transferred. I agree with the Supreme Court Decision. As decided by the Supreme Court, physicians will treat their patients more carefully and in case of necessity for transfer, physicians will transfer their patients with more caustion. However, the study for this issue should be continued hereafter because concrete standards are not given to lawers and physicians just by the Supreme Court Decisions itself.
