ABSTRACT
Purpose@#Propranolol is widely prescribed to psychiatric patients to control adrenergic symptoms. However, propranolol poisoning can be fatal due to cardiovascular complications. We analyzed associations between blood levels of propranolol and patients’ clinical features, with the aim of predicting progression to severe complications. @*Methods@#Data were collected from patients aged 18 years or older who presented to the emergency department with propranolol poisoning between January 2016 and May 2022. We retrospectively analyzed their medical records and compared blood levels of propranolol between those who had cardiovascular complications and those who did not. @*Results@#Two hundred patients were included in this study. The blood levels of propranolol were significantly higher in patients with hypotension, bradycardia, and prolonged QT intervals, with median values of 247.0 ng/mL (interquartile range [IQR], 56.5–333.8 ng/mL), 275.8 ng/mL (IQR, 154.3–486.4 ng/mL), and 159.0 ng/mL (IQR, 33.9–310.8 ng/mL), respectively. In the predictive analysis of cardiovascular complications using a receiver operating characteristic curve, the area under the curve was 0.729 with a cut-off value of 72.40 ng/mL (sensitivity, 0.667; specificity, 0.819). In addition, the correlation coefficient between blood levels and the amount of drug described during the history-taking at the time of presentation was 0.634, which was found to have a significantly higher relationship. @*Conclusion@#Because blood levels of propranolol can be used as predictors of exacerbation in patients with propranolol poisoning, patients with blood levels above 72.40 ng/dL require careful treatment and observation from their initial presentation at the emergency department.
ABSTRACT
A 44-year-old female patient who had been diagnosed with breast cancer visited our oncology department. She had developed right-side weakness and mild dysarthria, and MRI revealed a 4-cm cysticenhancing lesion in her left frontal lobe. Her surgery was postponed 48 hours after receiving 5-aminolevulinic acid (5-ALA), because a problem with thyroid function that had not been noticed before was discovered. The main lesion was enhanced on navigation and appeared to be a gross tumor; its 5-ALA uptake was very high. Specimens obtained from this location were histologically confirmed to contain tumor cells. The operation was completed, and removal of all enhancing lesions was confirmed by MRI within 24 hours postoperatively. The pathology report confirmed metastatic ductal carcinoma. The clinical efficacy of 5-ALA was confirmed even 48 hours after administration into a metastatic brain tumor from breast cancer.
ABSTRACT
BACKGROUND/OBJECTIVES@#Oxidative stress is caused by reactive oxygen species and free radicals that accelerate inflammatory responses and exacerbate fatigue. Tormentic acid (TA) has antioxidant and anti-inflammatory properties. Thus, the aim of present study is to determine the fatigue-regulatory effects of TA in H2O2 -stimulated myoblast cell line, C2C12 cells and treadmill stress test (TST) and forced swimming test (FST) animal models.MATERIALS/METHODS: In the in vitro study, C2C12 cells were pretreated with TA before stimulation with H2O2 . Then, malondialdehyde (MDA), lactate dehydrogenase (LDH), creatine kinase (CK) activity, tumor necrosis factor (TNF)-α, interleukin (IL)-6, superoxide dismutase (SOD), catalase (CAT), glycogen, and cell viability were analyzed. In the in vivo study, the ICR male mice were administered TA or distilled water orally daily for 28 days. FST and TST were then performed on the last day. In addition, biochemical analysis of the serum, muscle, and liver was performed. @*RESULTS@#TA dose-dependently alleviated the levels of MDA, LDH, CK activity, TNF-α, and IL-6 in H2O2 -stimulated C2C12 cells without affecting the cytotoxicity. TA increased the SOD and CAT activities and the glycogen levels in H2O2 -stimulated C2C12 cells. In TST and FST animal models, TA decreased the FST immobility time significantly while increasing the TST exhaustion time without weight fluctuations. The in vivo studies showed that the levels of SOD, CAT, citrate synthase, glycogen, and free fatty acid were increased by TA administration, whereas TA significantly reduced the levels of glucose, MDA, LDH, lactate, CK, inflammatory cytokines, alanine transaminase, aspartate transaminase, blood urea nitrogen, and cortisol compared to the control group. @*CONCLUSIONS@#TA improves fatigue by modulating oxidative stress and energy metabolism in C2C12 cells and animal models. Therefore, we suggest that TA can be a powerful substance in healthy functional foods and therapeutics to improve fatigue.
ABSTRACT
Background@#As a restorative material used to treat dental caries, the light-curing type resin is widely used, but it has the disadvantage of polymerization shrinkage. The Bulk-Fill composite resin was developed to solve these shortcomings, but the existing research mainly focused on comparing the physical properties of a composite resin and a Bulk-Fill resin. A study on the light curing time and distance of the Bulk-Fill resin itself tend to be lacking. @*Methods@#This study compares the surface microhardness of specimens prepared by varying the light curing time and distance of smart dentin replacement (SDR) as a flowable Bulk-Fill resin and Tetric N-ceram as a packable Bulk-Fill resin, and confirms the polymerization time and distance that becomes the optimum hardness. To determine the hardness of the specimen, it was measured using the Vickers Hardness Number (Matsuzawa MMT-X, Japan). @*Results@#In SDR, the surface microhardness decreased as the distance increased in all time groups in the change distance from the curing tip. In the change of light curing time with respect to the distance from curing tip, the surface microhardness increased as the time increased. In Tetric N-ceram, the surface microharness showed no significant difference in the change of the distance of curing tip in the group of 20 and 60 second. But in the group of 10 and 40 seconds, decreased as the distance increased. The surface microharness increased as the light curing time increased in all distance groups. @*Conclusion@#When using SDR and Tetric N-ceram in clinical practice, it is considered that as the distance from the polymerization reactor tip increases, a longer light curing time than the polymerization time recommended by the manufacturer is required.
ABSTRACT
Objective@#This study was designed to verify the effectiveness of capnography and ultrasound for confirmation of the location of the nasogastric tube (NGT) in the emergency room (ER). @*Methods@#In this prospective single-blinded study, carried out on 137 patients over 19 years of age, the NGT location was confirmed by capnography in 63 patients and by ultrasound in 74 patients. The capnography and ultrasound scans were performed in random order, while auscultation was performed and chest X-rays were taken for all patients. Capnography was performed by checking the end-tidal carbon dioxide (ETCO2) level and the wave form after inserting the NGT. An ultrasound scan was conducted on the neck, gastroesophageal junction and stomach. The X-ray results were interpreted by a doctor who had not inserted the NGT. @*Results@#The sensitivity and specificity of auscultation were 98.43% and 10%, respectively. After 30 cm of NGT was inserted ETCO2 was measured through the capnography, and was found to be ranging from 0-23. When the capnography showed an ETCO2 value of less than 4, the tube was considered to be inserted in the stomach. In such a case, the specificity was 100%, but the sensitivity was only 46.43%. The sensitivity and specificity of the ultrasound were 92.96% and 66.67%, respectively. In addition, the positive predictive value was confirmed to be 100% and 98.51% when using capnography and ultrasound, respectively. @*Conclusion@#When the NGT is inserted in the ER, it is possible to use ultrasound and capnography for confirmation of its location. However, in some patients, when neither method can confirm the location, a chest X-ray will still be needed.
ABSTRACT
Objective@#The vulnerable and frail elderly individuals are at a compounded risk of worsening, rather than recovering, from external stress such as sepsis. Ambulation is majorly considered as a phenotype and determining factor of frailty. This study was undertaken to determine whether inability of ambulation is predictive for the prognosis of elderly patients afflicted with sepsis. @*Methods@#Data were collected retrospectively from the medical records of an emergency medical center, from 1 November 2016 to 28 February 2017. Patients older than 65 years, who underwent blood culture or with a diagnosis of sepsis or septic shock and with Sequential Organ Failure Assessment (SOFA) score above 2 points, were included in the study. The predictive ability of the clinical factors was analyzed by comparing with the primary outcome of in-hospital mortality. @*Results@#A total of 105 patients were included in the study; 58 (55.2%) male and 47 (44.8%) female patients, with median age 78 years (range, 65-96 years). Of these, 89 (84.8%) patients were independently ambulatory before presentation. The median SOFA score was 3 (2-12), and 20 (19%) patients had expired in the hospital. Logistic regression revealed that inability of ambulation is not predictive of mortality (odds ratio, 0.872; 95% confidence Interval, 0.176-4.309; P=0.866). However, correlation analysis with the SOFA score revealed an association with inability of ambulation (r=0.277, P=0.004), and multiple regression analysis also showed that ambulation affects the SOFA score (t=2.435, P=0.017; t=-2.521, P=0.013). @*Conclusion@#Inability of ambulation does not predict in-hospital mortality, but affects the SOFA score of elderly patients afflicted with sepsis or in septic shock.

ABSTRACT
Zoletil is a combination of tiletamine hydrochloride and zolazepam hydrochloride used as a veterinary anesthetic. Although zoletil abuse is widely known, zoletil poisoning for the purpose of suicide is very rare. We present a case of a 39-year-old man who attempted suicide by intravenously injecting a large amount of zoletil, resulting in decreased mental status and severe respiratory depression. Intubation and mechanical ventilation were applied. After 30 hours in the hospital, all symptoms of poisoning improved. Because zoletil can cause severe respiratory depression, close observation and aggressive securement of an airway is mandatory

ABSTRACT
Point-of-care ultrasound (POCUS) is a useful tool that is widely used in the emergency and intensive care areas. In Korea, insurance coverage of ultrasound examination has been gradually expanding in accordance with measures to enhance Korean National Insurance Coverage since 2017 to 2021, and which will continue until 2021. Full coverage of health insurance for POCUS in the emergency and critical care areas was implemented in July 2019. The National Health Insurance Act classified POCUS as a single or multiple-targeted ultrasound examination (STU vs. MTU). STU scans are conducted of one organ at a time, while MTU includes scanning of multiple organs simultaneously to determine each clinical situation. POCUS can be performed even if a diagnostic ultrasound examination is conducted, based on the physician's decision. However, the Health Insurance Review and Assessment Service plans to monitor the prescription status of whether the POCUS and diagnostic ultrasound examinations are prescribed simultaneously and repeatedly. Additionally, MTU is allowed only in cases of trauma, cardiac arrest, shock, chest pain, and dyspnea and should be performed by a qualified physician. Although physicians should scan all parts of the chest, heart, and abdomen when they prescribe MTU, they are not required to record all findings in the medical record. Therefore, appropriate prescription, application, and recording of POCUS are needed to enhance the quality of patient care and avoid unnecessary cut of medical budget spending. The present article provides background and clinical guidance for POCUS based on the implementation of full health insurance coverage for POCUS that began in July 2019 in Korea.

ABSTRACT
Bamboo salt (BS) is a traditional Korean food, and has been reported to have anti-cancer, anti-inflammatory, and anti-metastatic effects. However, the anti-atopic dermatitis (AD) activity of BS has not been described yet. In the present study, we examined the preventive effect of BS on AD. The effect of oral administration of BS was tested in a 2, 4-dinitrofluorobenzene (DNFB)-induced AD animal model, by histological analysis, enzyme-linked immunosorbent assay, reverse transcription-polymerase chain reaction, caspase-1 assay, and Western blotting analysis. BS administration reduced the total clinical severity and scratching frequencies, compared with the AD group. In the serum of DNFB-induced AD mice, the levels of IgE, histamine, thymic stromal lymphopoietin (TSLP), interleukin (IL)-5, and IL-13 were significantly reduced by BS treatment. BS significantly reduced the protein and mRNA expression of TSLP, IL-6, and tumor necrosis factor-α in the AD skin lesions. BS markedly reduced the infiltration of inflammatory cells. Furthermore, the activation of caspase-1 was reduced by BS in the AD skin lesions. Our results suggested that BS should be considered as a candidate treatment for allergic inflammatory diseases including AD.

PURPOSE@#The regional emergency medical centers manage the patients with major blunt trauma according to the process appropriate to each hospital rather than standardized protocol of the major trauma centers. The primary purpose of this study is to evaluate the effectiveness and influence on prognosis of additional cervical-thoracic-lumbar-spine computed tomography (CTL-spine CT) scan in diagnosis of spinal injury from the victim of major blunt trauma with impaired consciousness.@*METHODS@#The study included patients visited the urban emergency medical center with major blunt trauma who were over 18 years of age from January 2013 to December 2016. Data were collected from retrospective review of medical records. Sensitivity, specificity, positive predictive value, and negative predictive value were measured for evaluation of the performance of diagnostic methods.@*RESULTS@#One hundred patients with Glasgow coma scale ≤13 underwent additional CTL-spine CT scan. Mechanism of injury was in the following order: driver, pedestrian traffic accident, fall and passenger accident. Thirty-one patients were diagnosed of spinal injury, six of them underwent surgical management. The sensitivity of chest, abdomen and pelvis CT (CAP CT) was 72%, specificity 97%, false positive rate 3%, false negative rate 28% and diagnostic accuracy 87%. Eleven patients were not diagnosed of spinal injury with CAP CT and C-spine lateral view, but all of them were diagnosed of stable fractures.@*CONCLUSIONS@#C-spine CT scan be actively considered in the initial examination process. When CAP CT scan is performed in major blunt trauma patients with impaired consciousness, CTL-spine CT scan or simple spinal radiography has no significant effect on the prognosis of the patient and can be performed if necessary.

PURPOSE: In 2012, a revised guideline for acute acetaminophen overdose was proposed in the UK, recommending that the treatment threshold should be lowered to 100 mcg/ml at 4 hours after ingestion without risk stratification of hepatotoxicity. However, the poison centers in some developing countries do not have laboratory resources to provide serum drug levels in time. The primary aim of the study is to evaluate the cut-off value of reported dose per kilogram to determine when N-acetylcysteine treatment is warranted under the revised guideline. METHODS: Data were collected retrospectively from the toxicology registry of an urban emergency medical center between 1st January 2010 and 30th June 2017. Inclusion criteria were single acute overdose of more than 75 mg/kg in 15 hours from ingestion and over 14 years of age. Subgroups were created by 25 mg/kg increments of reported dose, then sensitivity, specificity, positive predictive value and negative predictive value were calculated for the cutoff values of 100 mg/kg, 125 mg/kg, 150 mg/kg and 175 mg/kg for toxic serum level over ‘100-treatment line’. RESULTS: A total of 99 patients were enrolled in the study; 24 patients showed toxic serum levels (24.2%). Zero of 17 patients with an ingestion dose under 100 mg/kg showed toxic level (0%), and 0 of 15 under 125 mg/kg (0%), 2 of 14 under 150 mg/kg (14.3%), and 4 of 12 under 175 mg/kg (33.3%) had toxic levels. The higher the ingested dose per kilogram of weight, the higher the frequency of the toxic serum concentration on the first test (χ² test for trend, χ²=22.66, p-value < 0.001) and the sensitivity of each value was 100%, 100%, 92% and 76%. CONCLUSION: In acute single acetaminophen intoxication, the ingestion dose of 100 mg/kg of weight will be useful in determining the need for the N-acetylcysteine antidote in the indigent laboratory environment.

Regenerative therapy in an interproximal intrabony defect is a challenge due to unaesthetic appearance after surgery. In this article, we introduce a case series of additional use of autogenous periosteal barrier membrane combined with bovine bone mineral and enamel matrix derivative (EMD) in interproximal periodontal intrabony defects to overcome an aforementioned shortcoming. During the periodontal regenerative surgery, autogenous periosteal membrane was additionally adopted besides xenograft material and EMD. Clinical and radiographic examinations were performed before surgery and 6 months after surgical treatment. All clinical parameters were improved and the intrabony defects were resolved on the radiography 6 months after surgery. Moreover, soft tissue esthetics such as the contour of interdental papilla was better than that of conventional regenerative therapy. Periodontal regenerative therapy using several graft materials and bioactive materials was effective in the treatment of periodontal intrabony defect. Moreover, using of autogenous periosteal barrier membrane combined with xenograft and EMD has additional effect for the treatment of an interproximal intrabony defect in terms of augmentation of interdental soft tissue volume.

PURPOSE: Aspiration pneumonia is an important complication of drug intoxication with decreased mental status. The purpose of the study is to investigate the risk factors of aspiration pneumonia in the patients of benzodiazepine overdose with or without co-ingestion of other drugs. METHODS: A retrospective chart review of patients who visited the emergency department between January 2012 and December 2014 was conducted. Demographic data, time from ingestion to visit, initial vital signs, symptoms, mental status, medical history, laboratory results, chest radiological findings and co-ingested medications were recorded. Multiple logistic analyses were performed to verify the association between variables and the development of aspiration pneumonia. RESULTS: A total of 249 patients presented to the emergency department with benzodiazepine overdose. Aspiration pneumonia had developed in 24 patients (9.6%). Univariate analysis revealed time from ingestion to visit was longer, Glasgow coma scale score was lower, hypoxia was presented, leukocytosis was shown, types of ingested drugs was high, less activated charcoal was applied and tricyclic antidepressants was taken in patients that developed aspiration pneumonia. Time from ingestion to visit (odds ratio (OR) 1.121, 95% confidence interval (CI), 1.057-1.189, p=0.000), GCS score (OR 0.724. 95% CI, 0.624-0.839, p=0.000), oxygen saturation (OR 0.895, 95% CI, 0.835-0.959, p=0.002), and co-ingestion of TCA (OR 4.595, 95% CI, 1.169-18.063, p=0.029) were identified as risk factors of morbidity of aspiration pneumonia upon multiple logistic regression analysis. CONCLUSION: Time from ingestion to visit, low GCS score, low oxygen saturation and co-ingestion of TCA were risk factors of the development of aspiration pneumonia in benzodiazepine overdose patients.

PURPOSE: The objective of this study is to develop an adequate local disaster preparation program that integrates multiple institutes, ultimately saving time, human resources, and expenses. METHODS: The study proceeded in the orders of polls to the medical team before the drill and the lecture which were education on disaster, equipment, how to deal with the various situtuation, and performed the drill, debriefing session, and then reevaluated by polls after the drill. RESULTS: Among the 57 medical staffs, a comparison was made of the polls between before and after the simulation with respect to the treatment ability depending on disaster triage, understanding of disaster data transferring system, test on disaster understanding (p<0.001). However, the difference by work career was not statistically significant (p=0.206, p=0.665). CONCLUSION: We were able to develop a new program with a great response and understanding enabling us to adequately prepare for disasters. We may increase our ability to deal with such situations through unified training, not only within the hospital but also with local institutes through this well-structured program.
