Introduction: Tricyclic antidepressants often cause drug-induced QRS complex prolongation in overdose but are now less commonly prescribed. We sought to determine, among a contemporary cohort of patients, the pharmaceuticals independently associated with QRS complex prolongation in acute overdose.

Methods: We performed secondary analysis of data from the Toxicology Investigators Consortium (ToxIC) Core Registry.

Antiarrhythmic medications are fundamental in the acute and chronic management of pediatric arrhythmias. Particularly in the pediatric patient population, associated antiarrhythmic toxicities represent important potential adverse effects. Emergency medicine clinicians must be skilled in the detection, workup, and management of antiarrhythmic toxicity.

Introduction: 2,4-dinitrophenol (DNP) is a mitochondrial toxin sometimes used as a weight loss agent. Reports of fatalities from DNP have been increasing since 2000, suggesting an increase in use. Our understanding of DNP toxicity in humans comes from reports to Poison Control and postmortem analyses, sources that are biased to more extreme presentations.

Article Synopsis
  • Chronic doxepin toxicity in children is rare but can present with symptoms like confusion, ataxia, and seizures, often linked to factors like dosing errors, genetic differences, and interactions with other medications.
  • A case study of a 10-year-old boy showed chronic doxepin toxicity, misinterpreted as epilepsy, due to a high dose combined with drug interactions and genetic factors affecting metabolism.
  • Discontinuation of doxepin resolved all symptoms, highlighting the need for careful monitoring of dosages and drug interactions in pediatric patients receiving this medication.

Article Synopsis
  • The study investigates the rise in pediatric cannabis intoxications as more areas legalize recreational use, looking specifically at severe outcomes in emergency department cases from 2017 to 2020.
  • Researchers found that 38% of the 138 children studied were admitted to intensive care, with polysubstance use and ingestion of cannabis edibles identified as significant predictors of severe outcomes.
  • For children older than 10, polysubstance ingestion was the main risk factor for severe outcomes, while all younger children primarily ingested edibles, highlighting differences in risks based on age.

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).

Introduction: Bupropion toxicity can cause cardiogenic shock, ventricular dysrhythmias, and death. Clinical and electrocardiographic factors associated with adverse cardiovascular events in bupropion toxicity have not been well-studied. This study aimed to identify factors associated with adverse cardiovascular events in adult patients with isolated bupropion exposures.

Background: When ingested by children, small quantities of beta-adrenergic antagonists (BAA) are described as dangerous and even potentially lethal ("one pill can kill"). We characterize demographics, clinical characteristics, and the rate of serious outcomes among pediatric patients with reported BAA ingestions.

Methods: This study was a retrospective review of U.

The management of the poisoned patient often requires the utilization of uncommonly used pharmaceutical interventions. These interventions can be associated with significant costs to both the patient and treating institution. Pharmaceutical supply shortages and issues with accessibility of antidotal therapies complicate the management of many toxic exposures.

Objectives: Interventions requiring a PICU are rare in toxicologic exposures, but cardiovascular medications are high-risk exposures due to their hemodynamic effects. This study aimed to describe prevalence of and risk factors for PICU interventions among children exposed to cardiovascular medications.

Design: Secondary analysis of Toxicology Investigators Consortium Core Registry from January 2010 to March 2022.

Background: In the post-Roe era, barriers to facility-based abortions may lead to an increased incidence of self-managed abortions. While misoprostol-based medication abortions have significant literature supporting its safety profile, there is a knowledge deficit within the medical community regarding the toxicities of commonly used herbal abortifacients.

Methods: This is a narrative review, based on a MEDLINE and HOLLIS database search, of self-managed abortion methods with herbal abortifacients and their associated toxicities.

SARS-CoV-2 emerged in 2019 and led to the COVID-19 pandemic. Efforts to develop therapeutics against SARS-Cov-2 led to both new treatments and attempts to repurpose existing medications. Here, we provide a narrative review of the xenobiotics and alternative remedies used or proposed to treat COVID-19.

Background: Poisoning is an important cause of out-of-hospital cardiac arrest which can be challenging to manage. Neurological outcomes after poisoning-induced out-of-hospital cardiac arrest (POHCA) are yet to be fully elucidated. This retrospective cohort study sought to describe the characteristics of POHCA, and identify factors associated with favourable neurologic outcomes.

Introduction: Warfarin induces coagulopathy. Guidelines protocolize reversal of supratherapeutic international normalized ratio (INR) in patients dependent on anticoagulation, but practices vary for reversing warfarin-induced coagulopathy after overdose in non-warfarin-dependent patients.

Case Report: This is the report of a 15-year-old female who ingested her father's warfarin (100-200 mg) in a self-harm attempt.

Coronary atherosclerosis is the main cause of death worldwide. Advancing the understanding of coronary microstructure-based mechanics is fundamental for the development of therapeutic tools and surgical procedures. Although the passive biaxial properties of the coronary arteries have been extensively explored, their regional differences and the relationship between tissue microstructure and mechanics have not been fully characterized.

The rules of fair play in sport generally prohibit the use of performance-enhancing drugs (PEDs). The World Anti-Doping Agency (WADA) oversees global antidoping regulations and testing for elite athletes participating in Olympic sports. Efforts to enforce antidoping policies are complicated by the diverse and evolving compounds and strategies employed by athletes to gain a competitive edge.
