Identification of a novel opioid, -piperidinyl etonitazene (etonitazepipne), in patients with suspected opioid overdose.

Background: Novel opioids in the illicit drug supply, such as the "nitazene" group of synthetic opioids, present an ongoing public health problem due to high potency and respiratory depressant effects. We describe three patients in whom -piperidinyl etonitazene, a compound not previously reported in human exposure, was detected after suspected opioid overdose. Other substances that these patients tested for included fentanyl, cocaine, levamisole, phenacetin, benzoylecgonine, -fluorofentanyl, presumptive heroin (tested as 6-monoacetylmorphine (6-MAM), morphine, and codeine), and tramadol.

Ivermectin associated adverse events in the treatment and prevention of COVID-19 reported to the FACT pharmacovigilance project.

Background: In August 2021, the Centers for Disease Control and Prevention (CDC) released a health alert following the rapid increase in ivermectin prescriptions and reports of severe illness associated with use of products containing ivermectin for the prevention or treatment of COVID-19 infections. The United States Food and Drug Administration (FDA) and the CDC have explicitly discouraged the use of ivermectin in the prevention or treatment of COVID-19 outside of clinical trials. The study aims to describe the adverse events (AEs) related to ivermectin use for the prevention or treatment of COVID-19.

Fomepizole as an adjunctive therapy for acetaminophen poisoning: cases reported to the toxicology investigators consortium (ToxIC) database 2015-2020.

Introduction: Fomepizole inhibits formation of toxic acetaminophen (APAP) metabolites and may prevent or reverse mitochondrial toxicity. Given these mechanisms, it may be beneficial in patients with severe APAP toxicity. Current patterns of use for this indication are not well-studied.

Predictors of severe outcome following opioid intoxication in children.

Introduction: While the opioid crisis has claimed the lives of nearly 500,000 in the U.S. over the past two decades, and pediatric cases of opioid intoxications are increasing, only sparse data exist regarding risk factors for severe outcome in children following an opioid intoxication.

The Toxicology Investigators Consortium 2020 Annual Report.

The Toxicology Investigators Consortium (ToxIC) Registry was established by the American College of Medical Toxicology in 2010. The registry collects data from participating sites with the agreement that all bedside and telehealth medical toxicology consultation will be entered. This eleventh annual report summarizes the Registry's 2020 data and activity with its additional 6668 cases.

Failure of chelator-provoked urine testing results to predict heavy metal toxicity in a prospective cohort of patients referred for medical toxicology evaluation.

Introduction: Provoked urine testing (PUT), involving chelating agent administration prior to measuring urine metal excretion levels, is used by some alternative health care practitioners to diagnose patients with heavy metal poisoning. Multiple medical societies have advised against this practice due to its presumed unreliability, expense, and lack of validation. However, no prospective study of the predictive value of PUT for heavy metal poisoning has been undertaken.

Characterizing Trends in Synthetic Cannabinoid Receptor Agonist Use from Patient Clinical Evaluations during Medical Toxicology Consultation.

Synthetic cannabinoid receptor agonists (SCRAs) are a new class of compounds with profound psychoactive effects and potential toxicity. This study characterizes patterns in SCRA abuse using qualitative interviews with individuals receiving medical toxicology consultation. Patients with suspected exposure to a new psychoactive substance were interviewed by medical toxicologists upon presentation for acute care.

The Toxicology Investigators Consortium Case Registry-the 2019 Annual Report.

The Toxicology Investigators Consortium (ToxIC) Registry was established by the American College of Medical Toxicology (ACMT) in 2010. The Registry collects data from participating sites with the agreement that all bedside medical toxicology consultation will be entered. This tenth annual report summarizes the Registry's 2019 data and activity with its additional 7177 cases.

When It Comes to Snakebites, Kids Are Little Adults: a Comparison of Adults and Children with Rattlesnake Bites.

Background: Rattlesnake envenomations are a significant cause of morbidity in the USA. While pediatric rattlesnake envenomations are relatively common, data comparing adult and pediatric patients with rattlesnake envenomations remain limited.

Methods: This multi-center retrospective study used the North American Snakebite Registry (NASBR), a sub-registry of the Toxicology Investigator's Consortium (ToxIC).

Evaluating Effectiveness of Online Learning Modules in Pediatric Environmental Health Education.

Objective: Content and training about pediatric environmental health are lacking in healthcare professionals' education. In an initiative to improve pediatric environmental health education, the Pediatric Environmental Health Specialty Unit (PEHSU) program offers free, interactive, web-based ("eLearning") modules on environmental health topics. The aim of this study is to determine the effectiveness of PEHSU eLearning modules in increasing knowledge about pediatric and reproductive environmental health.

The Toxicology Investigators Consortium Case Registry-the 2018 Annual Report.

The Toxicology Investigators Consortium (ToxIC) Registry was established by the American College of Medical Toxicology (ACMT) in 2010. The Registry collects data from participating sites with the agreement that all bedside medical toxicology consultation will be entered. The objective of this ninth annual report is to summarize the Registry's 2018 data and activity with its additional 7043 cases.

Fatalities in poisoned patients managed by medical toxicologists.

Poisoning is a leading cause of injury-related death in the United States. The Toxicology Investigators Consortium (ToxIC) Case Registry, established by the American College of Medical Toxicology, prospectively captures patients who were directly cared for and managed at the bedside by medical toxicology services. We sought to describe exposure cases who presented to Emergency Departments (EDs) across ToxIC sites, received direct bedside care by medical toxicologists; however, the intoxication resulted in fatality.

Clinical predictors of adverse cardiovascular events for acute pediatric drug exposures.

Risk factors for adverse cardiovascular events (ACVE) from drug exposures have been well-characterized in adults but not studied in children. The objective of the present study is to describe the incidence, characteristics, and risk factors for in-hospital ACVEs among pediatric emergency department (ED) patients with acute drug exposures. This is a prospective cohort design evaluating patients in the Toxicology Investigators Consortium (ToxIC) Registry.

Loperamide misuse to avoid opioid withdrawal and to achieve a euphoric effect: high doses and high risk.

Introduction: Loperamide is a readily accessible nonprescription medication that is increasingly being used surreptitiously as an opioid substitute to alleviate the symptoms of acute opioid withdrawal. The objective of this study was to determine the clinical characteristics of patients with loperamide misuse and toxicity.

Methods: The ToxIC registry, a nationwide, prospectively collected cohort of patients evaluated by medical toxicologists was searched from November 2011-December 2016 for patients with loperamide exposure.

The Epidemiology, Clinical Course, and Management of Snakebites in the North American Snakebite Registry.

The American College of Medical Toxicology established the North American Snakebite Registry (NASBR), a national database of detailed, prospectively collected information regarding snake envenomation in the United States, in 2013. This report describes the epidemiology, clinical course, and management of snakebites in the NASBR. All cases entered into the NASBR between January 1, 2013 and December 31, 2015 were identified.

The Toxicology Investigators Consortium Case Registry-the 2016 Experience.

The Toxicology Investigators Consortium (ToxIC) Case Registry was established by the American College of Medical Toxicology in 2010.
