PURPOSE: The aim of the study was to compare the clinical characteristics in emergency endotracheal intubation procedures between non-elderly and elderly patients. METHODS: Data for airway registry, which were collected in two emergency departments (ED) between April 2006 and March 2010, were retrospectively reviewed. The airway registry data included patient's demographic information and variables such as Cormack-Lehane grade, 3-3-2 finger analysis, success rate, the number of attempts at intubation, complications of intubation, and clinical outcomes after intubation. RESULTS: A total of 1,457 patients were enrolled. The mean age of the patients was 62.2+/-15.7 and 62.1%(n=905) were male. A total of 726(49.8%) patients were classified as being in the elderly intubation group(> or =65 years). Cormack-Lehane grade, 3-3-2 finger analysis, the relationship between the number of attempts and success rate, the relationship between Cormack-Lehane classification and success rate, complications, and clinical outcomes after intubation showed no significant difference between elderly and non-elderly groups. CONCLUSION: Anatomical structures related to endotracheal intubation, the process and clinical outcomes of elderly patients are not different than for non-elderly adult patients. However, considering the lower physiologic reservoir and higher comorbidities of elderly patients, a more vigorous approach to emergency airway management in the elderly is needed.

Nicotine-poisoning related to the electronic cigarettes (e-cigarette) is increasing worldwide. Moreover, the American Association of Poison Control Centers has advised the public to use caution with e-cigarette devices and highly concentrated liquid nicotine after a surge in related poisonings. We report here the first case of nicotine poisoning from self-injected e-cigarette fluid in Korea. A 17-year-old male patient subcutaneously injected himself with 0.5 ml of nicotine solution for an electronic cigarette via the dorsum of his hand, after which he complained of nausea, vomiting, dizziness and dyspnea. His vital signs were within the normal range, but his mental status was drowsy. He was admitted for observation and the symptoms disappeared the following day. Sinus bradycardia with a rate of 45/min was observed on the third hospital day, but improved after 6 hours. He was discharged without complications.

PURPOSE: Extracorporeal life support (ECLS) is a term used to describe a number of modalities including extracorporeal membrane oxygenation (ECMO) to support cardiac and/or pulmonary systems. The purpose of this study is to review the available evidence regarding the effect of ECLS in patients with acute poisoning. METHODS: Electronic literature searches with PubMed, Embase, Cochrane library, and KoreaMed were conducted for identification of relevant studies addressing ECLS in treatment of acute poisoning. The literature search was conducted by two investigators in March, 2016 with publication language restricted to English and Korean. The toxic substance, technique of ECLS, and final outcome of each case were analyzed. RESULTS: The final analysis included 64 articles including 55 case reports. There were no articles classified according to a high level of evidence such as randomized trial and prospective cohort study. ECLS treatment was used in the management of patients poisoned with 36 unique substances. Venovenous ECMO was performed in 4 cases. Among the reported cases, 10 patients died despite treatment with ECLS. CONCLUSION: Evidence supporting ECLS for patients with acute poisoning is inadequate. However, many case reports suggest that early consideration of ECLS in poisoned patients with refractory cardiac arrest or hemodynamic compromise refractory to standard therapies may be beneficial.

PURPOSE: Automated external defibrillators (AEDs) could not recommend shock for ventricular fibrillation in the presence of electromagnetic interference. The purpose of this study was to examine the effect of an induced electromagnetic field on performance of AED. METHODS: The intensity of magnetic waves from commercial electric mats was measured. Three AEDs were attached to the resuscitation manikin and the question of whether shock would be recommended for simulated electrocardiogram of VF or normal sinus rhythm was tested. The simulation was repeated 10 times under the influence of 0, 5, and 18 µT magnetic field or electric mat. Relevant literature studies on electromagnetic interference on AED were reviewed. RESULTS: The magnetic flux density from the electric mat was measured to 5.67-6.1 µT in warming phase, and 2.25-2.84 µT in maintenance phase. There was no false positive or false negative recommendation of shock under the influence of 0, 5, and 18 µT magnetic field or electric mat. However, one AED detected motion even in the stationary state. Among 11 studies from the literature search, five studies reported misinterpretation of AED. Minor errors including delayed analysis, motion artefact, and noise in speakers were reported from 6 studies. CONCLUSION: Although we could not reproduce false negative interpretation, AED made a mistake in confusing electromagnetic interference with motion artefact. Therefore, emergency providers should be cautious not to use AED close to household appliances or medical equipment inducing electromagnetic interference.

Phentermine has been widely used as an appetite suppressant since 2004 in Korea. The authors experienced two cases of acute phentermine overdose and report with the literature review. A 36-year-old man and a 24-year-old woman presented together to the emergency department with taking 13 tablets (390 mg) of phentermine 16 hours ago. They had tachycardia, hypertension and complained visual symptoms, nausea, insomnia and anxiety. These symptoms were resolved by conservative management.

We report on a patient who developed acute hepatic failure despite intravenous N-acetyl cysteine therapy who was treated with the Molecular Adsorbents Recirculating System (MARS). She presented 20 hours after the ingestion of 13 g of acetaminophen. The MARS is based on albumin dialysis principle which can be applied for patients with acute poisoning from drugs that have high protein-binding capacity because of its ability to selectively remove from circulation protein-bound toxins. The clinical toxicologist should be consider this technology when treating patients with hepatic failure following acetaminophen poisoning.

Liposuction is one of the most frequently performed cosmetic surgeries worldwide for reshaping the body contour. Although liposuction is minimally invasive and relatively safe, it is a surgical procedure, and it carries the risk of major and minor complications. These complications vary from postoperative nausea to life-threatening events. Common complications include infection, abdominal wall injury, bowel herniation, bleeding, haematoma, seroma, and lymphoedema. Life-threatening complications such as necrotizing fasciitis, deep vein thrombosis, and pulmonary embolism have also been reported. In this paper, we provide a brief introduction to liposuction with the related anatomy and present computed tomography and ultrasonography findings of a wide spectrum of postoperative complications associated with liposuction.

PURPOSE: The purpose of this study is to compare the sensitivity, specificity, positive predictive value, and negative predictive value of ultrasonography versus magnetic resonance imaging (MRI) in evaluation of pregnant patients with clinically suspicious acute appendicitis. METHODS: This study was a retrospective cohort study. A total of 60 pregnant patients who presented to the emergency department with suspected appendicitis and underwent ultrasonography or MRI were included. The official interpretation reports and pathologic reports were extracted and analyzed. The sensitivity, specificity, positive predictive value, and negative predictive value were calculated for ultrasonography and MRI for diagnosis of acute appendicitis. We also calculated and compared area under the curve (AUC) of both diagnostic tests with the receiver operating characteristic (ROC) curve analysis. RESULTS: Among 60 patients, 43 (71%) underwent ultrasonography, 37 (61%) underwent MRI, and 20 (33%) underwent both diagnostic tests. Twenty patients were confirmed as pathologically-proven acute appendicitis. The sensitivity, specificity, positive predictive value, and negative predictive value of ultrasonography for diagnosing acute appendicitis were 67%, 77%, 53%, and 86%, while those of MRI were 100% for all parameters. In ROC analysis, the AUC was 0.656, respectively, for ultrasonography, and 1.000 for MRI (p value<0.0001). CONCLUSION: This study suggests that MRI is more accurate than ultrasonography for the diagnosis of acute appendicitis in pregnant women, especially when the appendix is invisible with ultrasonography.
