ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

INTRODUCTION: Exposures to hydrazines occur during aeronautic and space operations and pose a potential risk to personnel. Historically, extensive preparatory countermeasures have been taken due to concern for severe toxicity. This study seeks to better understand manifestations of acute occupational exposures to hydrazine to guide recommendations for management. MATERIALS AND METHODS: A retrospective database review of records from four United States regional poison centers was conducted of all human exposures to hydrazine, monomethylhydrazine, or 1,1-dimethylhydrazine over two decades. Following case abstraction, descriptive statistics were performed to characterize demographics, manifestations, treatments, and outcomes. RESULTS: One hundred and thirty-five cases were identified, and most were adult males exposed to inhaled hydrazine propellant vapors. Fifty-seven percent of patients were asymptomatic following exposure; otherwise, common symptoms were dyspnea, throat irritation, cough, ocular irritation, and headache. All patients were evacuated or received decontamination, with a few reports of symptomatic treatments, including oxygen supplementation and salbutamol (albuterol). Patients usually recovered quickly and were released after a brief healthcare facility evaluation or observed locally. No patients developed delayed symptoms. Symptoms of severe toxicity were not observed, and there were no deaths. DISCUSSION: Acute exposures to hydrazines during operations within the aerospace industry appear to be limited primarily to mucosal and mild pulmonary irritation without significant neurologic, hepatic, or hematologic toxicity. These findings are contrary to previously established expectations and may be related to low-level exposures or possibly due to current emergency countermeasures. CONCLUSIONS: Care in occupational hydrazine exposure will focus on evacuation, decontamination, and symptomatic management of chemical irritant properties of hydrazines. It is reasonable to manage mild cases outside of a healthcare facility. Continued endeavors in human space exploration and habitation will increase the risk of these exposures, making it imperative that clinicians be comfortable with the care and management of these patients.

ABSTRACT

BACKGROUND: The estimated serum osmolality is a measurement of solutes in the blood, including sodium, glucose, and urea, but also includes ethanol and toxic alcohols (e.g., methanol, ethylene glycol, diethylene glycol, isopropyl alcohol, propylene glycol) when present. These rarely measured toxic alcohols can elevate the serum osmolality, giving the true measured osmolality. The difference between that and a calculated osmolality is the osmolal gap, which can be elevated in many clinical scenarios such as renal failure, ingestion of toxic alcohols, diabetic ketoacidosis, shock, and others. CASE REPORT: We report a patient with a history of alcohol use disorder who came to the Emergency Department with an abnormally elevated osmolal gap in the setting of altered mental status. The patient's increased osmolal gap was further investigated while he was promptly treated with fomepizole, thiamine, and urgent hemodialysis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: We discuss the differential diagnosis for substances that increase the osmolal gap with respective ranges of elevation. This case demonstrates that although osmolal gap elevation is often attributed to the presence of toxic alcohols, other common etiologies may account for the gap, including acute renal failure and multiple myeloma.

ABSTRACT

Importance: The US and Canada currently have no formal published nationwide guidelines for specialists in poison information or emergency departments for the management of acetaminophen poisoning, resulting in significant variability in management. Objective: To develop consensus guidelines for the management of acetaminophen poisoning in the US and Canada. Evidence Review: Four clinical toxicology societies (America's Poison Centers, American Academy of Clinical Toxicology, American College of Medical Toxicology, and Canadian Association of Poison Control Centers) selected participants (n = 21). Led by a nonvoting chairperson using a modified Delphi method, the panel created a decision framework and determined the appropriate clinical management of a patient with acetaminophen poisoning. Unique to this effort was the collection of guidelines from most poison centers in addition to systematic collection and review of the medical literature. Comments from review by external organizations were incorporated before the guideline was finalized. The project began in March 2021 and ended in March 2023. Findings: The search retrieved 84 guidelines and 278 publications. The panel developed guidelines for emergency department management of single or repeated ingestion of acetaminophen. In addition, the panel addressed extended-release formulation, high-risk ingestion, coingestion of anticholinergics or opioids, age younger than 6 years, pregnancy, weight greater than 100 kg, and intravenous acetaminophen use. Differences from current US practice include defining acute ingestion as an ingestion presentation from 4 to 24 hours after overdose was initiated. A revised form of the Rumack-Matthew nomogram was developed. The term massive ingestion was replaced with the term high-risk ingestion and denoted by a specific nomogram line. Other recommendations include specific criteria for emergency department triage, laboratory evaluation and monitoring parameters, defining the role of gastrointestinal decontamination, detailed management of acetylcysteine treatment, associated adverse effects, and stopping criteria for acetylcysteine treatment, as well as criteria for consultation with a clinical toxicologist. Finally, specific treatment considerations, including acetylcysteine dosing, fomepizole administration, and considerations for extracorporeal elimination and transplant evaluation, were addressed. Conclusions and Relevance: This qualitative study provides a consensus statement on consistent evidence-based recommendations for medical, pharmacy, and nursing education and practice to optimize care of patients with acetaminophen poisoning.

ABSTRACT

INTRODUCTION: Calcium channel blockers (CCB) are a leading cause of ingestion-associated fatality. Angiotensin-converting enzyme inhibitor (ACEi) overdose as part of co-ingestion is common and associated with refractory shock. Treatment options to manage this profound vasoplegia are limited. We describe the first case of use of newly formulated Angiotensin II for treatment of severe ACEi and CCB poisoning. CASE REPORT: A 57-year-old man presented after suicide attempt by ingesting 20 tablets each of amlodipine 10 mg and benazepril 20 mg. His hypotension was initially managed with 35 mL/kg of crystalloid, norepinephrine, and hyperinsulinemic euglycemic therapy (HIET). His hemodynamics further deteriorated, and he developed lactic acidosis, electrolyte derangements, and renal dysfunction. Further complications of his ingestion included cardiac arrest, subsequent requirement for emergency cricothyrotomy, and renal replacement therapy. Maximal hemodynamic support with HIET therapy insulin drip 4.4 units/kg/hour, norepinephrine 2 mcg/kg/min, epinephrine 1 mcg/kg/min, vasopressin .06 units/hour, and intravenous lipid emulsion was unsuccessful. Ang II was started and titrated to maximal doses with dramatic improvement in hemodynamics. Within hours of starting Ang II, epinephrine was stopped and norepinephrine decreased by 50%. He was downgraded from the intensive care unit without any ongoing end-organ dysfunction. DISCUSSION: Isolated CCB overdoses have high complication rates and well-established treatments. Therefore, management of CCB and ACEi co-ingestion is typically driven by CCB poisoning algorithm. There are multiple reports of CCB and ACEi co-ingestions causing treatment-refractory shock. Therapeutic options are limited by toxicities and availability of salvage therapies. Ang II is a safe and highly effective option to manage these patients.

ABSTRACT

INTRODUCTION: Medical toxicology expertise has expanded into the addiction medicine realm including outpatient medication for opioid use disorder (MOUD) and addiction treatment. Concomitantly, the emergency department (ED) and hospital are increasingly seen as important sites for the screening, prevention, and treatment of patients with substance use disorders and addiction. This analysis seeks to characterize patients seen by medical toxicologists for opioid use and opioid use disorder (OUD) in the ED and inpatient consultation setting (inpatient) versus in the OUD clinic (outpatient) setting. METHODS: We searched the American College of Medical Toxicology's Toxicology Investigators Consortium Case Registry, a prospective, de-identified, national dataset that includes patients receiving medical toxicology consultation following prescription opioid misuse. The dataset also includes patients seen in outpatient MOUD clinics during the same period between June 2013 and November 2015. Intentional self-harm patients were excluded. We analyzed medical history, drug use patterns, and other factors with odds ratios and confidence intervals. RESULTS: Of 110 patients identified, 60 (54.5%) were inpatients and 50 (45.5%) outpatients. Mean age (39 years), gender (68% male), and race breakdown (60% white/non-Hispanic) were similar. The outpatient group was more likely to have Medicare/Medicaid coverage (p<0.0001). By history, the outpatient group was more likely to have past alcohol misuse, intravenous drug use, prescription drug misuse, and prescription opioid misuse. Most inpatient group members sought a recreational high compared to avoiding withdrawal or treating dependence in the outpatient group. CONCLUSION: Patients treated in the outpatient compared to inpatient setting were more likely to report adverse sequelae from their drug use including long-term drug use, depression, previous rehabilitation attempts, and seeking to avoid withdrawal.

ABSTRACT

BACKGROUND: Melia azedarach, also known as the chinaberry tree, is native to Southeast Asia and northern Australia but has become an invasive species in the United States. M. azedarach contains limonoid tetranotriterpenes, found in highest concentrations in its berries. Ingestion has been reported to result in adverse clinical effects affecting the gastrointestinal, cardiovascular, respiratory, and neurologic systems. OBJECTIVE: The objective of this investigation was to describe M. azedarach ingestions in Texas. METHODS: Cases were M. azedarach ingestions reported to Texas poison centers from 2000-2018. The distribution of cases was determined for various factors related to patient demographics, ingestion circumstances, management, and outcome. RESULTS: Of 990 total M. azedarach ingestions, 87.4% involved the berry. There was a seasonal pattern with 42.9% reported between March and May. The patients were male in 55.1% of cases; 86.6% of the patients were ≤5 years of age. Patients were managed outside of a health care facility in 89.9% of cases; 95.2% of the ingestions resulted in no or at most minor clinical effects. The most frequently reported clinical effects were gastrointestinal (8.9%) and neurologic (2.1%). The most common treatments were dilution (67.2%) and food/snack (16.8%). CONCLUSION: In this study that focused on M. azedarach ingestions reported to Texas poison centers, the ingestions tended to involve berries. Most of the patients were young children. The ingestions often occurred between March and May. The ingestions typically were managed outside of a health care facility and did not result in serious outcomes. The most common clinical effects were gastrointestinal and neurologic.

ABSTRACT

Introduction:Euphorbia tirucalli, commonly known as pencil cactus, is a member of the Euphorbiaceae family that produces a milky, white latex substance that can cause local irritation if ingested or comes in contact with the skin or eyes. This study characterized E. tirucalli exposures reported to a large, statewide poison center network.Methods: Cases were E. tirucalli exposures reported to the Texas Poison Center Network (TPCN) during 2000-2018. The distribution of cases was determined for various factors related to patient demographics, exposure circumstances, management, and outcome.Results: Of 678 total E. tirucalli exposures, the patient age distribution was 16.8% five years or less, 8.0% 6-12 years, 1.6% 13-19 years, and 72.1% 20 years or more; 55.6% were male. The most common exposure routes were ocular (60.9%), ingestion (31.9%), and dermal (17.3%). The exposure reason was unintentional in 97.5% of the exposures and occurred at the patient's own residence in 94.4%. The patient was managed outside of a healthcare facility in 66.5% of the cases, and 17.1% had potentially serious outcomes. The most common reported clinical effects were ocular (60.0%), dermal (14.0%), and gastrointestinal (12.1%).Conclusion: The majority of patients involved in E. tirucalli exposures reported to the TPCN were adults and male. The most common routes of exposure and clinical effects were ocular, ingestion, and dermal contact. Such information may prove useful for targeting education and prevention activities relating to E. tirucalli exposures.

ABSTRACT

BACKGROUND: Cycas revoluta (sago cycad or palm) is a popular ornamental plant in the United States. All parts of the plant contain toxins such cycasin and beta-methylamino-l-alanine, the ingestion of which can be harmful to humans and animals. The objective of this study was to characterize C. revoluta exposures reported to poison centers. METHODS: Cases were C. revoluta exposures reported to Texas poison centers during 2000-2018. The distribution of cases by selected variables was determined. RESULTS: Of 192 total C. revoluta exposures, the most common exposure routes were ingestion (55.7%) and dermal (34.4%). The patient age distribution was 28.1% 5 years or less, 15.1% 6-12 years, 4.7% 13-19 years, and 50.5% 20 years or more; 55.2% were male. The exposure was unintentional in 92.2% of the cases and occurred at the patient's own residence in 94.8%. The patient was managed on site in 78.6% of the cases, already at/en route to a healthcare facility in 12.0%, and referred to a healthcare facility in 8.9%. The most common reported clinical effects were dermal (23.4%), particularly puncture/wound (16.1%), dermal irritation/pain (14.6%), and edema (8.9%), followed by gastrointestinal (13.0%), particularly vomiting (8.9%) and nausea (7.8%). CONCLUSION: Most of the C. revoluta exposures tended to be unintentional and occurred at home. Although most of the C. revoluta exposures involved ingestion, 35% were dermal, and the most frequently reported clinical effects were dermal followed by gastrointestinal. Most of the exposures were not serious and were managed outside of a healthcare facility.

ABSTRACT

Emergency department (ED) providers have limited time to evaluate patients at risk for opioid misuse. A validated tool to assess the risk for aberrant opioid behavior may mitigate adverse sequelae associated with prescription opioid misuse. We sought to determine if SOAPP-R, COMM, and provider gestalt were able to identify patients at risk for prescription opioid misuse as determined by pharmacy records at 12 months. We conducted a prospective observational study of adult patients in a high volume US ED. Patients completed the SOAPP-R and COMM, and treating EM providers evaluated patients' opioid misuse risk. We performed variable-centered, person-centered, and hierarchical cluster analyses to determine whether provider gestalt, SOAPP-R, or COMM, or a combination, predicted higher misuse risk. The primary outcome was the number of opioid prescriptions at 12 months according to pharmacy records. For 169 patients (mean age 43 years, 51% female, 73% white), correlation analysis showed a strong relationship between SOAPP-R and COMM with predicting the number of opioid prescriptions dispensed at 12 months. Provider scores estimating opioid misuse were not related to SOAPP-R and only weakly associated with COMM. In our adjusted regression models, provider gestalt and SOAPP-R uniquely predicted opioid prescriptions at 6 and 12 months. Using designated cutoff scores, only SOAPP-R detected a difference in the number of opioid prescriptions. Cluster analysis revealed that provider gestalt, SOAPP-R, and COMM scores jointly predicted opioid prescriptions. Provider gestalt and self-report instruments uniquely predicted the number of opioid prescriptions in ED patients. A combination of gestalt and self-assessment scores can be used to identify at-risk patients who otherwise miss the cutoff scores for SOAPP-R and COMM.

ABSTRACT

BACKGROUND: Dietary supplement use (protein/amino acids, weight-loss supplements, performance enhancers) is common among U.S. military members. Reported dietary supplement use in deployed troops is limited and is of concern in settings where troops are exposed to high ambient temperatures, increased physical demands, and dehydration. Our objective was to describe dietary supplement use and adverse events (AEs) among deployed U.S. service members compared with their pre-deployment use. METHODS: We conducted an institutional review board (IRB) approved, descriptive study in Afghanistan using a written questionnaire and collected demographic information, dietary supplement use before and during deployment, AEs associated with supplement use, and physical workout routines. Participants were U.S. military personnel of all branches of service deployed to Afghanistan. They were recruited in high-traffic areas in the combat theater. We analyzed the data with descriptive statistics. Paired t-test/Wilcoxon signed-rank test was conducted to examine the before/during deployment changes for continuous data, and McNemar's chi-square test was conducted for categorical data. We constructed separate logistic regression models to determine the best predictors of increases or decreases in dietary supplement use, with demographic information, reasons for using supplements, and education requested/received as covariates in each model. All statistical tests were two-sided at a significance level of 5% (P < 0.05). RESULTS: Data were collected on 1685 participants. Ninety-seven of the participants were in the Army or Air Force. The participants were more likely to work out daily or more than once a day during deployment. Thirty-five percent of the participants reported no supplement use before or during deployment. The remaining 65% of participants reported increased use and increased frequency of use of supplements (e.g., daily) during deployment compared with pre-deployment. Additionally, more people followed label instructions strictly during deployment vs. pre-deployment. Overall, the frequency of self-reported AEs among supplement users remained consistent before and during deployment. The only significant difference noted was in problems falling or staying asleep, which increased during deployment. In the adjusted logistic regression models, the level of formal education, military branch, occupational specialty, education about dietary supplements, and certain reasons for using supplements (to boost energy, lose weight, gain muscle strength and mass, and as a meal replacement) were significant predictors of changes in supplement use. CONCLUSION: Deployed U.S. service members were more likely to use dietary supplements, use more than one supplement and use supplements more frequently during deployment than pre-deployment. No serious AEs were reported, but problems falling or staying asleep increased during deployment.

ABSTRACT

Opioid misuse is a growing epidemic among the civilian and military communities. Five hundred prospective, anonymous surveys were collected in the emergency department waiting room of a military tertiary care hospital over 3 weeks. Demographics, medical and military characteristics were investigated for association with opioid use. Univariate logistic models were used to characterize the probability of misuse in relation to the demographic, medical, and military-specific variables. Traumatic brain injury (TBI) and posttraumatic stress disorder were investigated within different age cohorts with adjustment for deployment. The opioid misuse rate disclosed by the subject was 31%. Subjects with TBI were less likely to misuse opioids. We found a trend among younger cohorts to have a higher likelihood for misusing opioids when diagnosed with TBI or posttraumatic stress disorder with history of deployment in the past 5 years. The most common form of misuse was using a previously prescribed medication for a new pain. Traumatic brain injury and/or enrollment in post-deployment recovery programs maybe protective against opioid misuse. Chronic opioid use among young soldiers maybe viewed as a weakness that could influence opioid misuse. Younger cohorts of active duty service members could be at higher risk for misuse. Efforts to enhance close monitoring of misuse should address these at-risk populations.

ABSTRACT

BACKGROUND: Trauma patients sustaining blunt injuries are exposed to multiple radiologic studies. Evidence indicates that the risk of cancer from exposure to ionizing radiation rises in direct proportion to the cumulative effective dose (CED) received. The purpose of this study is to quantify the amount of ionizing radiation accumulated when arriving directly from point of injury to San Antonio Military Medical Center (SAMMC), a level I trauma center, compared with those transferred from other facilities. METHODS: A retrospective record review was conducted from 1st January 2010 through 31st December 2012. The SAMMC trauma registry, electronic medical records, and the digital radiology imaging system were searched for possible candidates. The medical records were then analyzed for sex, age, mechanism of injury, received directly from point of injury (direct group), transfer from another medical facility (transfer group), computed tomographic scans received, dose-length product, CED of radiation, and injury severity score. A diagnostic imaging physicist then calculated the estimated CED each subject received based on the dose-length product of each computed tomographic scan. RESULTS: A total of 300 patients were analyzed, with 150 patients in the direct group and 150 patients in the transfer group. Both groups were similar in age and sex. Patients in the transfer group received a significantly greater CED of radiation compared with the direct group (mean, 37.6 mSv vs 28 mSv; P=.001). The radiation received in the direct group correlates with a lifetime attributable risk (LAR) of 1 in 357 compared with the transfer group with an increase in LAR to 1 in 266. CONCLUSION: Patients transferred to our facility received a 34% increase in ionizing radiation compared with patients brought directly from the injury scene. This increased dose of ionizing radiation contributes to the LAR of cancer and needs to be considered before repeating imaging studies. LEVEL OF EVIDENCE: III.

ABSTRACT

OBJECTIVES: Oseltamivir (Tamiflu) is approved by the Food and Drug Administration and is advertised for the treatment of influenza types A and B. Patient perceptions of its efficacy have not been adequately studied. Recent systematic reviews have called the benefits of this drug into question relative to the cost and adverse effect profile. We hypothesized that most people would be unaware of the efficacy, cost, or adverse effect profile of the drug. Our objective was to determine patient perceptions of efficacy, cost, and adverse effect profile of oseltamivir for the treatment of influenza. METHODS: This was a cross-sectional, multiple-choice, open-response survey of adult patients and adult caregivers of pediatric patients who presented to the emergency department (ED) with flu-like symptoms. Flu-like symptoms were defined as any respiratory symptom plus fever or body aches. The study took place during the 2014-2015 flu season at a rural ED. We analyzed the data, with descriptive statistics reported as frequencies/percentages for categorical data. Survey data collected as Likert scale data were summarized using mean, median, and mode. RESULTS: During the 4-month period, 70 surveys were completed. A total of 67% of the participants were women, with 84% younger than 40 years. Subjects younger than 40 years were more likely to have seen advertising for oseltamivir (31% vs 0%, P = 0.04). Less than half reported having received the flu vaccine that year. Most reported that oseltamivir was an effective treatment for the flu. Most overstated the perceived efficacy of oseltamivir. Most were not willing to take the medication if it had adverse effects, with the most deterring adverse effects being potential kidney and liver injury. CONCLUSIONS: In our study most patients reported overly positive expectations for the efficacy of oseltamivir for treating influenza. Most reported that commonly listed adverse effects would deter their use of the medication.
