Background/Objectives: Pediatric foreign body (FB) ingestion is a common clinical problem that frequently necessitates time-sensitive decisions regarding esophagogastroduodenoscopy (EGDS). Although established high-risk criteria guide the indication for EGDS, coins—despite their high prevalence—are not uniformly classified as high-risk FBs. In this study, we aimed to delineate epidemiology and endoscopic outcomes and to identify predictors of EGDS. Methods: We retrospectively reviewed cases of children younger than 15 years presenting to an urban emergency department (ED) with suspected or confirmed FB ingestion between 2014 and 2020. After applying exclusion criteria, 757 patients remained for analysis. Data abstracted included demographic characteristics, presenting symptoms, type and location of FB, ED length of stay (EDLOS), and whether EGDS was performed along with its outcomes. Multivariable logistic regression was used to identify predictors of EGDS, including age group, sex, symptom presence, established high-risk criteria, and type of FB (coin, button battery, magnet). Results: Among 757 children (median age 17.0 months; 54.0% male), 55.2% were asymptomatic. EGDS was performed in 47 of the 757 children (6.2%), with a success rate of 74.5% (35/47). Among EGDS cases, the most common foreign bodies were coins (29.8%), button batteries (27.7%), and magnets (17.0%). In multivariable models, established high-risk criteria were the dominant determinant of EGDS (adjusted OR ≈ 179.4; 95% CI, 29.9–1075.8; p < 0.001). Compared with button batteries, coin ingestion was independently associated with EGDS (adjusted OR ≈ 7.26; 95% CI, 1.07–49.31; p = 0.042). Conclusions: Established high-risk criteria were the primary determinant of EGDS, and coin ingestion showed a possible independent association with EGDS; these findings suggest that coin ingestion may warrant consideration as a potential high-risk factor when determining whether endoscopy is indicated.

Background/Objectives: Influenza poses significant risks in children, causing complications like febrile seizures and hospitalizations. Antiviral treatments include oseltamivir and peramivir, both FDA-approved neuraminidase inhibitors. This study aims to compare the effectiveness of intravenous peramivir and oral oseltamivir in pediatric patients presenting to an emergency department, with a primary focus on the revisit rate within 72 h post-treatment. Methods: A retrospective study analyzed 1327 children aged 1–15 years diagnosed with influenza A or B between 1 January 2019 and 29 February 2020, at a single urban hospital. Patients were divided into oseltamivir (n = 1243) and peramivir (n = 84) groups. Data included demographics, clinical symptoms, emergency department stays, and revisit rates. Fisher’s exact test was used for analysis, with p-values < 0.05 considered significant. Results: A total of 1327 pediatric patients were included, with 1243 receiving oseltamivir and 84 receiving peramivir. Patients in the peramivir group were older (median age 5.88 years vs. 4.54 years, p = 0.002) and had higher rates of gastrointestinal symptoms. The emergency department length of stay was significantly longer in the peramivir group (167 min vs. 63 min, p < 0.001). The revisit rate within 3 days was 5.63% for oseltamivir and 9.52% for peramivir, with no statistically significant difference (p = 0.22). Conclusions: Peramivir presents as an effective alternative treatment for influenza in children, particularly in situations where oral administration is not feasible due to gastrointestinal intolerance, highlighting the importance of an alternative route of antiviral administration.

Background: Percutaneous dilatational tracheostomy (PDT) is a common procedure in intensive care units (ICUs). Although it is thought to be safe and easily performed at the bedside, PDT usually requires endotracheal guidance, such as bronchoscopy. Here, we assessed the clinical outcomes and safety of PDT conducted without endotracheal guidance.Methods: In the ICU and coronary ICU at a tertiary hospital, PDT was routinely performed without endotracheal guidance by a single medical intensivist using the Griggs technique PDT kit (Portex Percutaneous Tracheostomy Kit). We retrospectively reviewed the electronic medical records of patients who underwent PDT without endotracheal guidance.Results: From January 1 to December 31, 2018, 78 patients underwent PDT without endotracheal guidance in the ICU and coronary ICU. The mean age of these subjects was 71.9±11.5 years, and 29 (37.2%) were female. The mean Acute Physiology And Chronic Health Evaluation (APACHE) II score at 24 hours after admission was 25.9±5.8. Fifty patients (64.1%) were on mechanical ventilation during PDT. Failure of the initial PDT attempt occurred in 4 patients (5.1%). In two of them, PDT was aborted and converted to surgical tracheostomy; in the other two patients, PDT was reattempted after endotracheal reintubation, with success. Minor bleeding at the tracheostomy site requiring gauze changes was observed in five patients (6.4%). There were no airway problems requiring therapeutic interventions or procedure-related sequelae.Conclusions: PDT without endotracheal guidance can be considered safe and feasible.

Background: The utilization of renal replacement therapy (RRT) is crucial for the management of patients with acute kidney injury (AKI) in emergency departments (EDs). The prompt initiation of RRT, encompassing both intermittent hemodialysis (HD) and continuous renal replacement therapy (CRRT), is acknowledged as beneficial for critically ill patients. The purpose of this study is to investigate the implementation of RRT within EDs and its impact on ED length of stay (EDLOS) in South Korea. Methods: This retrospective study utilized data from the National Emergency Department Information System (NEDIS) for the year 2019 to assess the utilization of RRT in emergency medical centers (EMCs) across South Korea. The analysis focused on RRT, which includes intermittent HD and CRRT, as identified through insurance billing codes for patients treated during ED visits and subsequent admissions. EMCs were categorized into three groups based on the frequency of RRT sessions, and the median EDLOS was evaluated. Results: Among 5,937,569 ED visits to Level I and II emergency medical centers (EMCs), 40,130 cases (0.68%) received RRT. Of the 162 EMCs, 58 centers (35.8%) did not perform intermittent HD in the ED and 106 centers (65.4%) did not perform CRRT in the ED during the study period. Centers that frequently performed CRRT in the ED showed significantly longer EDLOS compared with centers that seldom or never performed CRRT (588 min [IQR 286–767] vs. 270 min [IQR 147–337] and 205 min [IQR 149–363], respectively; p = 0.01). Regional disparities in the availability of ED-based RRT were also observed across South Korea. Conclusions: The frequency of RRT administration in EMCs in South Korea varied by region and facility. ED-based RRT utilization was associated with longer EDLOS, particularly in centers frequently performing CRRT. These findings suggest that patient acuity, institutional characteristics, and RRT-related resource utilization should be considered when evaluating EMC performance based on EDLOS.

Licorice is a perennial herb belonging to the legume family that mainly grows in northeastern China, Mongolia, Siberia, and other regions. It is used in traditional medicine in the form of dried roots in the East and the West. The main active component of licorice, glycyrrhizin, is known to produce mineralocorticoid effects when consumed chronically, which can lead to apparent mineralocorticoid excess syndrome. Herein, we present the case of a 72-year-old woman who was admitted to the emergency room with severe generalized weakness and difficulty keeping her neck upright, which had developed after daily consumption of licorice-infused water for the past 2 months. Blood tests revealed metabolic alkalosis and severe hypokalemia, and an electrocardiogram showed ventricular bigeminy. The patient was treated with daily potassium and spironolactone supplements, leading to a significant improvement in muscle strength after a week. One week later, the patient was discharged, showing rare ventricular premature contractions on electrocardiography, but with no specific complaints. Chronic licorice ingestion leading to hypokalemia and muscle weakness can be life-threatening, necessitating the discontinuation of the causative agent, close monitoring, and cautious supplementation of potassium and spironolactone as treatment.
