Modification of HEART Pathway for Patients With Chest Pain: A Korean Perspective

Background and Objectives@#The History, Electrocardiography, Age, Risk factors, and Troponin (HEART) pathway was developed to identify patients at low risk of a major adverse cardiac event (MACE) among patients presenting with chest pain to the emergency department. @*Methods@#We modified the HEART pathway by replacing the Korean cut-off of 25 kg/m2 with the conventional threshold of 30 kg/m2 in the definition of obesity among risk factors. The primary outcome was a MACE within 30 days, which included acute myocardial infarction, primary coronary intervention, coronary artery bypass grafting, and all-cause death. @*Results@#Of the 1,304 patients prospectively enrolled, MACE occurred in 320 (24.5%). The modified HEART pathway identified 37.3% of patients as low-risk compared with 38.3% using the HEART pathway. Of the 500 patients classified as low-risk with HEART pathway, 8 (1.6%) experienced MACE, and of the 486 low-risk patients with modified HEART pathway, 4 (0.8%) experienced MACE. The modified HEART pathway had a sensitivity of 98.8%, a negative predictive value (NPV) of 99.2%, a specificity of 49.0%, and a positive predictive value (PPV) of 38.6%, compared with the original HEART pathway, with a sensitivity of 97.5%, a NPV of 98.4%, a specificity of 50.0%, and a PPV of 38.8%. @*Conclusions@#When applied to Korean population, modified HEART pathway could identify patients safe for early discharge more accurately by using body mass index cut-off levels suggested for Koreans.

Association between initial fibrinogen levels and adverse outcomes in emergency department patients with primary postpartum hemorrhage

Objective@#This study evaluates the association between the initial fibrinogen levels and adverse outcomes in emergency department (ED) patients with primary postpartum hemorrhage (PPH). @*Methods@#This retrospective observational study was performed between January 2004 and December 2021 in the ED of a university-affiliated tertiary referral center. Primary PPH patients with fibrinogen level assessments in the ED were included. Patients were classified into two groups: the adverse outcome group-defined as patients receiving massive transfusion (transfusion of ≥10 units of packed red blood cells within the initial 24 hours), uterine artery embolization or emergency hysterectomy, intensive care unit admission, and in-hospital mortality-and the non-adverse outcome group. @*Results@#Of the 481 patients included in the study, 276 (57.4%) had adverse outcomes. The median fibrinogen level in patients with adverse outcomes was lower than in patients without adverse outcomes-149.5 mg/dL (range, 66.8-228.8) vs. 288.0 mg/dL (range, 215.0-349.0), respectively; P<0.001. The area under the receiver operating characteristic curve of the initial fibrinogen level for adverse outcomes was 0.811 (95% confidence interval, 0.773-0.849; P<0.001). The occurrence of adverse outcomes increased with decreasing fibrinogen levels (P<0.001). When the cutoff value of the initial fibrinogen level was 400 mg/dL, the sensitivity and negative predictive values for predicting adverse outcomes were 98.6% and 84.6%, respectively. When the cutoff value of the initial fibrinogen level was 100 mg/dL, the specificity and positive predictive values were 96.6% and 92.8%, respectively. @*Conclusion@#The initial fibrinogen levels on ED admission are associated with adverse outcomes.

Cancer patients with neutropenic septic shock: etiology and antimicrobial resistance

Background/Aims@#Among patients with febrile neutropenia that developed after chemotherapy, high-risk patients, such as those having clinical instability or Multinational Association of Supportive Care in Cancer score of < 21, require hospitalization for intravenous empiric antibiotic therapy. Monotherapy with an anti-pseudomonal ß-lactam agent is recommended. Although many studies reported the microbial etiology of infections and resistant patterns of febrile neutropenia, the patients were not well characterized as having neutropenic septic shock. Therefore, this study aimed to determine the microbial spectrum of infections and resistance patterns of their isolates in patients with chemotherapy-induced neutropenic septic shock. @*Methods@#Data of adult patients diagnosed with neutropenic septic shock in the emergency department between June 2012 and December 2016 were extracted from a prospectively compiled septic shock registry at a single academic medical center. Thereafter, microbiological studies and antimicrobial susceptibility tests were conducted. @*Results@#In total, 109 bacteria were found in patients with neutropenic septic shock. Gram-negative bacteria were the predominant causative organisms (84, 77.1%). Moreover, 33 microorganisms (30.3%) were multidrug-resistant (MDR) bacteria with extended-spectrum ß-lactamase-producing Escherichia coli (17, 50%) being the commonest. The most commonly affected sites in patients with MDR bacterial infections were the gastrointestinal tract (45%) and unknown (43.5%). Approximately 48.5% of MDR bacteria were resistant to cefepime but not to piperacillin- tazobactam or carbapenem. @*Conclusions@#MDR bacteria were prevalent in patients with chemotherapy-induced neutropenic septic shock. Therefore, piperacillin-tazobactam or carbapenem may be considered as empiric antibiotics if MDR bacteria are suspected to be causative agents.

Carbon monoxide poisoning caused by gas water heaters in Korea

Objective@#This study aimed at evaluating the characteristics and outcomes of patients who were diagnosed with carbon monoxide (CO) poisoning after using a gas water heater and to describe similar CO poisoning incidents involving gas water heaters in Korea. @*Methods@#We reviewed gas water heater-related CO poisoning affected patients who visited our emergency department (ED) from January 1, 2008, to December 31, 2019, and the CO poisoning incidents due to gas water heaters reported by the Korea Gas Safety Corporation (KGS) from January 1, 2000, to December 31, 2019. @*Results@#During the study period, a total of eight patients visited our ED as a result of five incidents. All five incidents occurred while using a gas water heater in an enclosed space. Five patients were poisoned by CO while taking a shower, and the other three were poisoned by CO while washing their hair. Most patients complained of a transient loss of consciousness, headache, dizziness, and general weakness. The mean value of the initial CO-hemoglobin level was 27.2±14.2% with a range of 7.2-45.7%. All the patients admitted survived after being given hyperbaric oxygen therapy and subsequently discharged from hospital. A total of 32 incidents that involved 71 victims were identified from the KGS. Of these victims, 24 were already dead at the scene, with an estimated case-fatality rate of 33.8%. Most incidents occurred while the victims were showering using a gas water heater installed in a bathroom with poor ventilation. @*Conclusion@#The present study showed that CO poisoning can occur even in a short time, such as taking a shower or shampooing hair, due to the use of a gas water heater installed in a closed space with poor ventilation. Also, it highlights the fact that the prehospital case-fatality rate of such CO poisoning is high.

Factors prognostic of ruptured hepatocellular carcinoma presenting to the emergency department

OBJECTIVE@#This study assessed whether characteristics of ruptured hepatocellular carcinoma (HCC) at presentation to the emergency department (ED) affect patient outcomes, and evaluated factors prognostic of HCC, particularly treatment modalities.@*METHODS@#This retrospective study between 2008 and 2017 evaluated patients presenting to an ED with ruptured HCC. Parameters associated with 30- and 90-day mortality were investigated, and clinical characteristics and treatments were analyzed.@*RESULTS@#In total, 121 patients presented to the ED with ruptured HCC. Of these, 29 died within 30 days. Multivariate logistic regression analysis showed that platelet count (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.976–0.995) and prothrombin time (OR, 16.20; 95% CI, 1.91–137.23) were associated with a 30-day mortality rate, whereas presence or absence of acute abdominal pain and shock at presentation to the ED was not significant. Patients who underwent embolization had a lower 30-day mortality rate than those treated conservatively (OR, 0.04; 95% CI, 0.001-0.20). Sixtyone patients died within 90 days after presentation to the ED. Serum albumin concentration (OR, 0.25; 95% CI, 0.09–0.71) was associated with 90-day mortality. Moreover, patients who underwent embolization (OR, 0.19; 95% CI, 0.06–0.60) and emergency hepatectomy (OR 0.09; 95% CI, 0.01–0.99) had lower 90-day mortality rates as compared to patients treated conservatively.@*CONCLUSION@#Presence of acute abdominal pain at presentation to the ED does not affect patient outcomes. Early aggressive treatments, such as embolization or emergency hepatectomy, were observed to improve outcomes in patients with ruptured HCC.

The biomass charcoal with reduced carbon monoxide emission decreases mortality after the biomass charcoal burning in mice

OBJECTIVE: This study examined the effects on mortality and cell death after biomass charcoal combustion, in which carbon monoxide (CO) emissions were reduced using a biomass combustion improver in mice. METHODS: The biomass (glycerin) charcoal (Biomass CharCoal by Pusan National University, BCCP) was generated in the Power Generation System laboratory, Pusan National University. The effects and molecular mechanisms of biomass charcoal in carbon monoxide poisoning were examined by analyzing the mouse mortality, circulating leukocytes, carboxyhemoglobin (COHb), and expression of the inflammation-related genes, and cleaved capase-3 using enzyme-linked-immunosorbent-assays, real-time polymerase chain reaction, or Western blotting. RESULTS: The mortality rates were lower in the BCCP-exposed mice than in the raw charcoal-exposed mice. The circulating leukocytes were lower in the BCCP-exposed mice than in the raw charcoal-exposed mice. On the other hand, there was no significantly difference in the levels of COHb between both mice. Interestingly, the expression of the apoptosis-related gene, cleaved-capase 3, and the inflammation and tissue necrosis-related gene and receptor for the advanced glycation end products were reduced markedly in the BCCP-exposed mice compared to the raw charcoal-exposed mice. Decreased inflammation and tissue necrotic factors could be molecular mechanisms for the decreased mortality rates after BCCP burning. CONCLUSION: Biomass charcoal (BCCP) reduced the mortality rates and inflammation and tissue necrotic factors by 30%–40%. These results suggest that the biomass charcoal (BCCP) could reduce the incidence of suicide and CO-associated delayed symptoms after charcoal burning. Furthermore, it could extend the time for rescue in suicide attempts using charcoal burning.

Characteristics of orbital wall fractures in preschool and school-aged children

OBJECTIVE: This study aimed to evaluate the injury patterns in pediatric patients with an orbital wall fracture (OWF) and to identify the differences in injury patterns between preschool and school-aged patients with OWF who presented to the emergency department. METHODS: We performed a retrospective observational study in the emergency department of a tertiary hospital between January 2004 and March 2014. A total of 177 pediatric patients (7 years) pediatric groups. RESULTS: The inferior wall was the most common fracture site in both the preschool and school-aged pediatric groups (50.0% vs. 64.4%, P=0.15). The male-to-female ratio and the mechanism of injury showed significant differences between the two age groups. Violence was the most common mechanism of injury in the school-aged pediatric group (49.3%), whereas falls from a height caused OWF in approximately half of the patients in the preschool pediatric group (42.9%). Concomitant injuries and facial fractures had a tendency to occur more frequently in the school-aged pediatric group. CONCLUSION: Significant differences according to the sex and mechanisms of injury were identified in preschool and school-aged pediatric patients with OWF.

Extracorporeal cardiopulmonary resuscitation among patients with out-of-hospital cardiac arrest

OBJECTIVE: Extracorporeal cardiopulmonary resuscitation (ECPR) may be considered as a rescue therapy for patients with refractory cardiac arrest. Identifying patients who might benefit from this potential life-saving procedure is crucial for implementation of ECPR. The objective of this study was to estimate the number of patients who fulfilled a hypothetical set of ECPR criteria and to evaluate the outcome of ECPR candidates treated with conventional cardiopulmonary resuscitation. METHODS: We performed an observational study using data from a prospective registry of consecutive adults (≥18 years) with non-traumatic out-of-hospital cardiac arrest in a tertiary hospital between January 2011 and December 2015. We developed a hypothetical set of ECPR criteria including age ≤75 years, witnessed cardiac arrest, no-flow time ≤5 minutes, low-flow time ≤30 minutes, refractory arrest at emergency department >10 minutes, and no exclusion criteria. The primary endpoint was the proportion of good neurologic outcome of ECPR-eligible patients. RESULTS: Of 568 out-of-hospital cardiac arrest cases, 60 cases (10.6%) fulfilled our ECPR criteria. ECPR was performed for 10 of 60 ECPR-eligible patients (16.7%). Three of the 10 patients with ECPR (30.0%), but only 2 of the other 50 patients without ECPR (4.0%) had a good neurologic outcome at 1 month. CONCLUSION: ECPR implementation might be a rescue option for increasing the probability of survival in potentially hopeless but ECPR-eligible patients.

Efficient utilization of the limited number of emergency medicine specialists and statistics related to clinical outcomes in the emergency department

OBJECTIVE: The supply of emergency medicine (EM) specialists has not been able to meet demand in the past decade. This study comparatively analyzed clinical findings to provide fundamental data to inform efficient utilization of a limited number of EM specialists. METHODS: This retrospective study included 54,204 patients who visited the emergency department of a tertiary care medical center from March 1 to December 31, 2012. The experimental specialist-supervised (SS) group included patients supervised by an EM specialist, while the control specialist-on-call (SOC) group included patients attended by a senior resident of EM with an EM specialist on call. RESULTS: The mean length of stay in the emergency department was longer in the SS group than in the SOC group for all levels of severe-to-moderate (levels 1 to 3) and mild (levels 4 and 5) patient conditions (P<0.05). The mortality rate of severe-to-moderate patients in the SOC group was 1.63 times higher than that in patient in the SS group. CONCLUSION: Supervision by EM specialists significantly decreased mortality in patients with severe-to-moderate condition. Therefore, EM specialists should focus on this patient group, while training residents should concentrate on patients with relatively mild conditions.

Comparison of Clinical Feature and Prognosis between Unilateral and Bilateral Acute Pyelonephritis

PURPOSE: Acute pyelonephritis (APN) usually presents as a mild disease. However, it has been shown to cause substantial morbidity and mortality on occasion. Therefore, it is important to distinguish between the complicated and uncomplicated APN. The purpose of this study was to determine the clinical significance of bilateral APN compared with unilateral APN in the emergency department (ED). METHODS: We analyzed the data of 303 consecutive patients with APN who underwent a abdominal computed tomography (CT) examination in the ED from January 2012 to December 2014. We compared the clinical presentation, progress, and outcomes between the unilateral and bilateral APNs that were identified on the CT scan. RESULTS: Of these 303 patients, 110 patients (36.3%) were confirmed as bilateral APN by the CT. The proportion of male was higher in the bilateral APN group (20.0% vs. 10.9%, p=0.029). Moreover, patients in the bilateral group visited the ED post symptom onset (6.5±7.8 vs. 3.6±3.1, p<0.001). However, symptom, sign, laboratory test, and CT findings were not statistically different between the two groups. In addition, severity, resistant pathogen, and outcomes such as occurrence of septic shock, hospital days, and mortality were also not different. CONCLUSION: This study suggests that bilateral APN, as determined by a CT, does not have clinical significance compared with unilateral APN.

Do We Have to Check Pulmonary Thromboembolism in Patients with Deep Vein Thrombosis in Emergency Department?

PURPOSE: Deep vein thrombosis (DVT) is a risk factor of pulmonary thromboembolism (PTE), however it is not clear who should be evaluated for a PTE and a DVT at the same time. The purpose of this study is to determine the clinical characteristics of PTE in patients with DVT who visited the emergency department (ED). METHODS: This was a retrospective cohort study of ED patients who visited with DVT and were simultaneously evaluated for a PTE from January 2012 to December 2013. We compared clinical characteristics between non-PTE and PTE patients with confirmed DVT in the ED. RESULTS: Of these 166 patients, 96 patients (57.8%) were confirmed PTE by computed tomography. In multivariate analysis, patients with PTE had more systemic neoplasm (OR 2.03, 95% CI 1.04-3.93, p=0.037) and right heart strain pattern in electrocardiography (OR 5.29, 95% CI 1.71-16.36, p=0.004) than patients without PTE. Femoral DVT was more likely in the non-PTE group (87.1% vs. 65.6%, p=0.002) and popliteal DVT was more likely in the PTE group (62.9% vs. 80.2%, p=0.013). However the number of DVT sites including both femoral and popliteal vein was not statistically different. CONCLUSION: In patients with systemic neoplasm or right heart strain patterns in electrocardiography, simultaneous PTE evaluation may be required in patients with DVT.

Etiology of Pleural Effusions in Cancer Patients

PURPOSE: The purpose of this study is to examine the causes of Pleural effusion (PE) in cancer patients and to compare the clinical characteristics between malignant PE (MPE) and non-MPE. METHODS: All consecutive cancer patients with PE who underwent diagnostic thoracentesis from January 1, 2008 to March 31, 2011 were analyzed retrospectively. RESULTS: A total of 719 patients were included; mean age was 58.4+/-13.6 years and 44.5% were female. The most common cause of PE was MPE (57.7%), followed by parapneumonic or empyema in 16.3%. However, the etiology was significantly different according to primary tumor origin and subtypes of lung cancer. While MPE was most common in lung, breast, and gynecologic cancer, hepatic hydrothorax was the main cause in Hepatocellular carcinoma (HCC). MPE accounted for 85.2% in adenocarcinoma, and 30.2% and 58.8% in squamous cell and small cell carcinomas, respectively. Patients with MPE were younger (57.0 vs. 60.2 years) and female-dominant (55.4% vs. 29.6%) compared to those with non-MPE. MPE had the large size (53.5% vs. 34.9%) and left location of PE (31.3% vs. 19.4%) more frequently than non-MPE, and fewer neutrophils (15.4% vs. 30.6%) and more lymphocytes (32.2% vs. 28.2%), higher levels of pH (7.33 vs. 7.29), and lower levels of glucose (111.5 vs. 129.7 mg/dL) than non-MPE (p<0.001 for all). CONCLUSION: Overall, MPE was the most common cause of PE in cancer patients. However the etiology of PE was significantly different according to primary tumor origin and subtypes of lung cancer. A difference in age, gender, size and location of PE, cell count, pH, and glucose was observed between MPE and non-MPE.

Clinical Features of Acute Aortic Dissection Patients Initially Diagnosed with ST-segment Elevation Myocardial Infarction

PURPOSE: Acute myocardial infarction (AMI) concomitant with acute aortic syndrome (AAS) is rare but prompt recognition of concomitant AAS is critical, particularly in patients with ST-segment elevation myocardial infarction (STEMI) because misdiagnosis with early thrombolytic or anticoagulant treatment may result in catastrophic consequences. This study examined the clinical features of patients of STEMI concomitant with AAS that may be a diagnostic clue. METHODS: Between January 1, 2010 and December 31, 2014, 22 patients who had the initial diagnosis of acute coronary syndrome (AMI and unstable angina) and AAS (aortic dissection, intramural hematoma, and ruptured thoracic aneurysm) in our emergency department were reviewed. Among them, 10 patients who were transferred from other hospitals and 4 patients with non-STEMI were excluded, leaving 8 patients of STEMI concomitant with AAS for analysis. RESULTS: The mean age of study patients was 57.5+/-16.31 years and five patients were Stanford type A and three patients were type B aortic dissection. Six patients had ST-segment elevation in anterior leads and 2 patients in inferior leads. Most patients had acute onset and severe chest pain, but none had dissecting nature chest pain. Serum troponin I was elevated in three patients but all patients had Ddimer elevation. Aortic regurgitation or regional wall motion abnormality was detected in four patients, and widened mediastinum was observed in all study patients. CONCLUSION: Concomitant AAS might be suspected in patients with STEMI who have elevated D-dimer and widened mediastinum.

Type and treatment of toxic mushroom poisoning in Korea

To eat unidentified or misidentified mushrooms taken from the wild can be very dangerous. In the vast majority of toxic mushroom ingestions in Korea, the mushroom was incorrectly identified. In general, poisoning of toxic mushrooms can be classified into seven types according to the toxins that they contain; amatoxin, gyromitrin, coprine, muscarine, ibotenic acid-muscimol, psilocybin-psilocin and gastrointestinal irritants. When clinicians care for a patient who ingested a toxic mushroom, it is very important to identify what kind of mushroom may have caused a patient's illness. But, in clinical practice, accurate botanical identification of the mushroom can be very difficult. Therefore, for estimating the caused mushroom and adequate treatment of poisoning, clinicians should know the type and treatment of toxic mushroom poisoning.

Incidence and Clinical Features of Esophageal Perforation Caused by Ingested Foreign Body / 대한소화기학회지

BACKGROUND/AIMS: Esophageal perforation is a rare but often a life-threatening condition. However, the incidence and clinical features of esophageal perforation caused by ingested foreign body are unknown. This study investigated the incidence of esophageal perforation caused by ingested foreign body and evaluated the clinical features and outcome of patients with esophageal perforation. METHODS: Among a total of 196 adult patients with confirmed esophageal foreign body and complained of at least one of the related symptoms at the emergency department between January 2000 and July 2008, 18 patients with esophageal perforation due to esophageal foreign body ingestion were included in the study. Data were collected by retrospectively reviewing the electric medical records. RESULTS: The incidence of esophageal foreign body and esophageal perforation in adults was 19.4% (196/1,009) and 1.8% (18/1,009), respectively. Chest pain was the most common symptom and fishbone was the most common foreign body causing esophageal perforation. Mediastinitis or mediastinal abscess occurred in 13 patients (13/18, 72.2%). About half (8/18) of the patients were admitted to the intensive care unit but there was no in-hospital mortality. CONCLUSIONS: The incidence of esophageal perforation in patients with foreign body ingestion was low but it increased up to 9.2% in patients with esophageal foreign body. However, prognosis was favorable with timely proper treatment. Chest pain can be an ominous sign indicating the presence of esophageal perforation in patients with esophageal foreign body.

Early Antibiotic Administration and Mortality in Patients with Septic Shock in Emergency Department

PURPOSE: The Surviving Sepsis Campaign recommend initiating broad spectrum antibiotics within the first hour of recognition of septic shock. An unknown proportion of the effectiveness of earlier antibiotics administration will remain in septic shock patients treated with an early quantitative resuscitation in emergency department (ED). We were to compare the 28-day mortality between earlier antibiotic administration (< or =1 hour) and early antibiotic administration (1 hour to 6 hour) in septic shock patients in ED. METHODS: A total of 536 consecutive septic shock patients were prospectively collected from January 2010 to June 2012. We identified 357 patients who were developed shock at initial assessment, and measured the time of initial antibiotics administration. The primary outcome was 28-day mortality. RESULTS: Mean age was 62.8+/-13.7 years old and 222 patients were male (62.2%). The median time from shock recognition-to-antibiotics administration was 94.0 min (IQR 47.0-150.0) and 28-day mortality rate was 20.2%. When the relationship of 28-day mortality between earlier antibiotic administration (< or =1 hour) and early antibiotic administration (1 hour to 6 hour) was compared, no significant difference was shown (19.5% vs. 20.5%, p=0.82). CONCLUSION: Earlier antibiotics administration may have no additional outcome value in septic shock patients treated with an early quantitative resuscitation in ED.

A Case of Acute Lung Injury due to Mercury Vapor Inhalation / 대한내과학회지

Mercury is traditionally used as a dye for making amulets in Korea. Inhaling the vapor produced by burning mercury damages major organs, such as the lungs, kidneys, and brain. We herein present a case of a 41-year-old man who complained of abdominal pain and dyspnea. A chest X-ray and computed tomography scan showed infiltration in both upper lung lobes. A thorough medical history revealed that the patient had made amulets prior to developing symptoms, and blood and urine tests confirmed elevated levels of mercury. Dimercaptosuccinic acid was used to chelate the mercury, and methylprednisolone was used to treat the acute lung injury. No kidney or nervous system complications were detected during follow-up. Inhalation of mercury vapor should be suspected in patients with acute lung injury involving both upper lobes.
