An Analysis of Clinical Outcomes of Exploratory Pediatric Metformin Ingestions Reported to the Texas Poison Center Network From 2011 to 2021.

Background: Poison centers develop triage threshold guidelines for pediatric metformin ingestions. Our network uses 1700 mg, or 85 mg/kg. Objective: To describe the dose, clinical course, and outcomes for inadvertent metformin ingestions in children 5 years old and younger reported to our statewide poison center network. Methods: We searched the poison center database 2011 to 2021 for metformin ingestions in patients 5 years and younger. Variables included age, sex, weight, dose, symptoms, outcome, and more. We used descriptive statistics with medians and interquartile ranges (IQR) for continuous variables. Results: Of 669 cases, exposures by age were 208 (31.1%) 1 to 2 years, and 275 (41.1%) 2 years. Weight was recorded in 342 (51.1%) (median 13.5 kg; IQR: 3.7 kg), and dose in 149 (22.3%) (median 500 mg; IQR: 500 mg). Milligram/kilogram values were available for 103 (15.4%) with median 42.4 mg/kg, IQR: 39 mg/kg. Most (647, 98.5%) exposures were unintentional. Most (445/669, 66.5%) were managed at a non-healthcare facility, while 204 (30.7%) were already at or referred to a healthcare facility. Of these 204 patients, 169 (82.8%) were evaluated and treated at the emergency department and discharged. Four (2%) were admitted to critical care, and 7 (3.4%) to the ward. Medical outcomes by effect were 5 (0.7%) minor, 2 (0.3%) moderate, 253 (37.8%) none, 292 (43.6%) not followed (minimal effects possible), and no major effects or deaths. Of 20 clinical occurrences reported, vomiting was most common (8, 1.2%). Conclusion: Despite little recorded dosage information, pediatric metformin ingestions under 85 mg/kg had predominantly uneventful medical outcomes.

Fasciotomy following North American pit viper envenomation in Texas 2004-2021.

INTRODUCTION: North American pit viper envenomation occurs over 4,000 times annually in the United States, with polyvalent Fab antivenom being the primary treatment. Fasciotomy is occasionally performed due to concerns about compartment syndrome. We utilized our direct access to Texas Poison Center Network data to create a new snakebite abstraction form and database on relevant available information between 2004 and 2021 and to identify, describe, and estimate the incidence of fasciotomy following pit viper envenomation in Texas. METHODS: We searched the Texas Poison Center Network database for cases during 2004-2021 using keywords such as fasciotomy, surgery, compartment pressure, and compartment syndrome. Descriptive statistics summarized the data. RESULTS: Of 16,911 reported envenomations, 0.69 percent involved fasciotomies (n = 117). Most common bite sites were digits/hands and lower extremities. Patients who underwent fasciotomy were typically male, aged 20-59, and 10 years younger than the total snakebite population. Only 6 percent of reported compartment syndrome cases had a compartment pressure measurement. Antivenom was administered in 101 (86.3 percent) cases, 92 (91.1 percent) of which received only Fab antivenom product. Patients with bites from rattlesnakes (47.9 percent) were associated with most fasciotomies. DISCUSSION: Our findings suggest a potential increase in snakebite exposures, accompanied by a decrease in fasciotomies. Overall, copperheads constituted the majority of snakebites, but most fasciotomies were from rattlesnake envenomations (47.9 percent). In this cohort, compartment syndrome diagnosis and decisions regarding fasciotomy were primarily based on clinical evaluation/surgeon expertise without compartment pressure measurements. Despite the efficacy of antivenom, only 86.3 percent of patients in our study received antivenom. CONCLUSIONS: Fasciotomy after North American pit viper envenomation in Texas is uncommon (0.69 percent) and has decreased over time, possibly due to increased antivenom use or surgeon comfort with nonsurgical management.

Implementation of an education session on buprenorphine induction in the emergency department, a resident-led initiative.

INTRODUCTION: Many physicians including emergency medicine physicians report insufficient training and education on prescribing buprenorphine for opioid use disorder. As emergency departments implement buprenorphine induction protocols, educational sessions can provide physicians with further familiarity with the treatment of opioid use disorder. This quality improvement project aimed to address the barrier of physician education in the implementation of buprenorphine initiation in the emergency department and presents a model for resident-led education sessions of emergency medicine physicians. METHODS: The project was a resident-led educational quality improvement project on educating members of the Department of Emergency Medicine on buprenorphine induction. The thirty-minute educational session included a pre-test survey, lecture, practice case workshop, questions, post-test survey, and a discussion. The survey questions were designed for physicians including residents and faculty, but medical students were invited to complete the session. RESULTS: Physicians including faculty and resident physicians responded positively to the educational survey, with an increase from 42.5 to 100% responding that they understood the risks and benefits of prescribing buprenorphine in the emergency department pre and post-survey respectively. Based on post-survey results, 88.5% of physicians responded that they planned to prescribe buprenorphine in the emergency department for patients meeting clinical criteria after completing the educational session. CONCLUSION: The results suggest that a resident-led training session can encourage peer involvement in buprenorphine induction to treat opioid use disorder in the emergency department.

Two Cases of Thyrotoxicosis due to Redotex Ingestion, a Mexican Weight Loss Drug.

BACKGROUND: Redotex™ is a Mexican weight-loss supplement that is not U.S. Food and Drug Administration-approved. It consists of the following five ingredients: tri-iodothyronine 75 µg, atropine 0.36 mg, diazepam 8 mg, aloin 16 mg, and d-norpseudoephedrine 50 mg per tablet. There are few case reports with clinically severe ingestions. We report two cases of clinical thyrotoxicosis due to use of Redotex. CASE REPORTS: A 29-year-old woman presented to the emergency department (ED) with anxiety and palpitations. She reported taking Redotex daily for 1 week. Her temperature was 37.1°C, blood pressure (BP) was 166/104 mm Hg, and heart rate (HR) was 140 beats/min. Laboratory analysis was significant for a bicarbonate level of 20 mmol/L (reference 22-29 mmol/L), free T4 0.75 ng/dL (reference 0.93-1.70 ng/dL), and thyroid-stimulating hormone (TSH) 0.05 uIU/mL (reference 0.27-4.20 uIU/mL). She was treated with 2 mg i.v. lorazepam and 20 mg oral propranolol. A 37-year-old woman presented with chest pain, palpitations, and nausea after taking Redotex 1 to 2 tablets daily for 6 weeks. Her HR was 134 beats/min and BP was 130/66 mm Hg. Thyroid function tests on initial presentation showed a TSH of 0.013 uU/mL, free T4 of 0.24 ng/dL, and free T3 of >30 pg/mL. She was treated with propranolol 1 mg i.v. twice per day and 2 doses of lorazepam 1 mg. Both patients had resolution of their symptoms. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: When taken chronically and at recommended doses, Redotex can present with clinically significant T3 thyrotoxicosis. This has not been seen in prior reports.

Characteristics of prior emergency departments visits associated with subsequent opioid overdose.

OBJECTIVES: In this study, we aim to identify and discuss the clinical and demographic characteristics of previous emergency department (ED) patient visits, at one of the only two medical centers in Staten Island, the epicenter of the opioid epidemic within Staten Island, who subsequently present to the ED with an opioid overdose. DESIGN: This was a retrospective, observational study of all patients presenting to the emergency ED between July 1, 2010 and December 31, 2015. SETTING: The study was conducted at Staten Island University Hospital. The ED has a census of 120,000 patient visits per year. PATIENTS: All adult patients ≥ 18 years of age, with an ICD-9 code consistent with opioid intoxication and a history of intentional or unintentional overdose were included. MAIN OUTCOME MEASURE: Clinical and demographic characteristics of previous ED patient visits who subsequently presented to the ED with an opioid overdose. RESULTS: One hundred and twenty-four subjects with a median age of 30 years [interquartile range, 24-40] were reviewed. Eighty-seven (70 percent) were males. Fifty-five subjects were admitted, 68 discharged, and one death. Patients were not more likely to present at any specific time of day. The most common past medical history was anxiety (21 percent), depression (20 percent), back pain (15 percent), hypertension (14 percent), and seizure disorder (11 percent). The most common past surgical history was a prior orthopedic procedure (11 percent). CONCLUSIONS: This study identified clinical and demographic characteristics of previous ED patient visits who subsequently present to the ED with an opioid overdose. These characteristics will be vital toward an increased understanding of subjects who subsequently experience an opioid overdose.
