INTRODUCTION: The USA continues to face a fentanyl-driven overdose epidemic. Prior research has demonstrated users of illicit opioids are concerned about fentanyl exposure and overdose, but the strategies they report using to detect fentanyl's presence lack empirical support. This study compares self-report and biologically detected fentanyl use and investigates overdose risk and risk reduction behaviors among a sample of high-risk people who use opioids. METHODS: Structured enrollment interviews conducted as part of a larger clinical trial assessed self-reported fentanyl exposure as well as strategies used to determine believed fentanyl exposure and prevent overdose among 240 participants enrolled at a Chicago, IL syringe service program...

BACKGROUND: Gender diversity in both emergency medicine and medical toxicology has grown over the last decade. However, disparities in promotion, awards, and speakership still exist. No studies have examined gender disparities in authorship in medical toxicology journals. RESEARCH QUESTIONS: Does the proportion of female first authors and female senior authors in medical toxicology publications increase over time? What factors predict female authorship in the first author or last author positions in two major medical toxicology journals? METHODS: We performed a retrospective review of all non-abstract publications in two medical toxicology journals, Clinical Toxicology and Journal of Medical Toxicology, between 2011 and 2020...

INTRODUCTION: ∆-8 tetrahydrocannabinol (THC) is a psychoactive cannabinoid and structural isomer of ∆-9 THC that is technically legal under United States Federal law. Commercial ∆-8-THC products being sold are currently unregulated. This study aims to (1) describe the advertising and labeling of Δ-8 THC retail products; (2) compare the advertised amount of Δ-8 THC for each product to that found during independent laboratory analysis; and (3) evaluate the presence and amount of other cannabinoids in those products...

INTRODUCTION: Carbon monoxide (CO) is a colorless and odorless gas that is a leading cause of environmental poisoning in the USA with substantial mortality and morbidity. The mechanism of CO poisoning is complex and includes hypoxia, inflammation, and leukocyte sequestration in brain microvessel segments leading to increased reactive oxygen species. Another important pathway is the effects of CO on the mitochondria, specifically at cytochrome c oxidase, also known as Complex IV (CIV)...

INTRODUCTION: For many years, the standard of care in the USA has been to treat acute lead encephalopathy with a combination parenteral dimercaprol (BAL) and CaNa2 EDTA. We present a case of a pediatric patient with severe lead encephalopathy, complicated by cardiac arrest, who was treated with an alternative regimen when CaNa2 EDTA was unavailable. CASE REPORT: A 24-month-old male was brought by ambulance to an emergency department (ED) with new onset seizures and sustained a cardiac arrest...

Since 2010, medical toxicology physicians from the American College of Medical Toxicology (ACMT) Toxicology Investigators Consortium (ToxIC) have provided reports on their in-hospital and clinic patient consultations to a national case registry, known as the ToxIC Core Registry. De-identified patient data entered into the registry includes patient demographics, reason for medical toxicology evaluation, exposure agents, clinical signs and symptoms, treatments and antidotes administered, and mortality. This thirteenth annual report provides data from 7206 patients entered into the Core Registry in 2022 by 35 participating sites comprising 52 distinct healthcare facilities, bringing the total case count to 94,939...

INTRODUCTION: Medical toxicology is a small but growing specialty. To ensure that the specialty continues to grow and attract strong candidates, it is important to understand what influences physicians to pursue medical toxicology training. This would allow for targeted interventions to recruit strong candidates to the field. METHODS: A cross-sectional survey was sent via email to current medical toxicology fellows and to medical toxicologists who completed fellowship in the last 5 years...

INTRODUCTION: Assays for ethylene glycol (EG) with a rapid turn-around time are not routinely available. Clinicians must rely on historical features and readily available clinical tests, combined with clinical acumen, to guide the initial management of suspected EG poisoning. Hypocalcemia has been suggested as a clue supporting the diagnosis of EG poisoning in patients presenting with an unexplained high anion gap metabolic acidosis (HAGMA). A previous small study challenged this assumption...

INTRODUCTION: Ethylene glycol (EG) is a frequently considered toxicant in poisoned patients. Definitive diagnosis relies on gas chromatography (GC), but this is unavailable at most hospitals. A glycerol dehydrogenase (GDH)-based assay rapidly detects EG. A rapid turnaround time and wide availability of necessary instrumentation suggest this method could facilitate the rapid detection of EG. METHODS: This is a prospective, observational analysis of banked, remnant serum samples submitted to the laboratory of a large, multi-hospital healthcare system...

INTRODUCTION: Chronic tricyclic antidepressant toxicity is rarely described in children. Symptoms include confusion, ataxia, and seizures. Toxicity may result from dosing error, CYP2C19 and CYP2D6 genetic variability, and drug-drug interactions. Chronic doxepin toxicity has not been previously reported in children. Doxepin is prescribed for insomnia and depression, with a maximum off-label dose of 3 mg/kg in children. We present a case of chronic doxepin toxicity mimicking epilepsy in a child attributable to three potential factors: supratherapeutic dosing, pharmacogenomic variability, and drug-drug interactions...

INTRODUCTION: Acetaminophen (APAP) toxicity remains a significant cause of adult and pediatric liver failure in North America and Europe. Previous research has evaluated the impaired mitochondrial function associated with APAP toxicity. The primary aim of this study was to evaluate the effects of APAP toxicity on platelet mitochondrial function using platelet oxygen consumption in a murine model in vivo. Our secondary objectives were to determine the effect of 4-MP on platelet mitochondrial function and hepatic toxicity in the setting of APAP overdose, and to correlate platelet mitochondrial function with other markers of APAP toxicity...
