More than 20 years that have elapsed since the inaugural American College of Medical Toxicology Spring Conference in 2002. During this time, the now ACMT Annual Scientific Meeting has grown in many ways, as demonstrated by the increase in attendance and abstract submissions, and diversification of educational offerings, and partners. Most importantly, the scientific rigor and presentation of new knowledge has continued to mature, and the conference is now firmly rooted in the annual educational schedule for medical toxicologists...

Since 2010, the American College of Medical Toxicology (ACMT) Toxicology Investigators Consortium (ToxIC) has maintained the ToxIC Core Registry, a national case registry of in-hospital and clinic patient consultations submitted by medical toxicology physicians. Deidentified 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 fourteenth annual report provides data from 7392 patients entered into the Core Registry in 2023 by 36 participating sites comprising 61 distinct healthcare facilities, bringing the total case count to 102331 between 2010 and 2023...

Likelihood ratios compare two values (i.e., case rates) in order to illustrate the magnitude of the difference between the two. This ratio increases the confidence one can have in a diagnostic test from a different vantage point than that of sensitivity and specificity. The calculations of likelihood ratios are presented along with a simplified approach. Likelihood ratios are another tool the toxicologist should employ in their understanding of statistics and probability.

INTRODUCTION: Thallium is a highly toxic metal, with most publications demonstrating poisoning from thallium salts. We report on a patient with elevated serum and urine thallium concentrations from an intentional ingestion of elemental thallium purchased from the internet for self-harm. CASE REPORT: The regional poison center was contacted about an 18-year-old man who ingested a fragment from a 100-gram bar reported to be elemental thallium. Serial serum and urine thallium concentrations were obtained...

INTRODUCTION: This study investigated exposures involving ∆8-tetrahydrocannabinol (∆8-THC) reported to US poison centers (PCs), including variation among states and regions. It evaluated whether the ∆8-THC exposure rate was lower among states with ∆8-THC regulations and states where cannabis (∆9-THC) use was legal. METHODS: National Poison Data System data for ∆8-THC exposures in 2021-2022 were analyzed, including comparisons of state and regional population-based exposure rates...

INTRODUCTION: Vortioxetine is an antidepressant with a multimodal mechanism of action. It is used as a treatment option for patients with major depressive episodes. There have only been two previously reported non-fatal overdoses of vortioxetine; neither of these were analytically confirmed There has also been one case of serotonin syndrome potentially related to vortioxetine and two deaths where vortioxetine was detected. We report here a non-fatal analytically confirmed case of vortioxetine overdose...

INTRODUCTION: Propylhexedrine is an over-the-counter nasal decongestant used recreationally for amphetamine-like effects. Prior reports have associated intravenous misuse with brainstem dysfunction and diplopia. This is a case of propylhexedrine ingestion resulting in neurological impairment with associated MRI findings. CASE REPORT: A 21-year-old man presented with neurologic symptoms after ingesting propylhexedrine extracted from a 250 mg nasal inhaler into a lemon juice solution following recommendations from an online forum...

INTRODUCTION: Quetiapine is available in both immediate-release (IR) and extended-release (XR) formulations. Quetiapine XR overdose is known to cause delayed increase in serum quetiapine concentrations. However, it is not certain whether quetiapine IR overdose would similarly cause a delayed increase in serum quetiapine concentrations. CASE REPORT: A 57-year-old woman with depression who was taking half a tablet of 25 mg quetiapine IR daily was transported to our emergency department with a complaint of disturbance of consciousness 12 h after a quetiapine IR overdose...

BACKGROUND: Acetaminophen toxicity remains one of the most common causes of liver failure and is treated with a course of n-acetylcysteine (NAC). This exceptionally effective medication is traditionally administered using a complicated three-bag protocol that is prone to administration errors. OBJECTIVE: We aimed to assess whether switching to a novel two-bag protocol (150 mg/kg over 1 h followed by 150 mg/kg over 20 h) reduced administration errors while not increasing liver injury or anaphylactoid reactions...

The Toxicology Investigators Consortium (ToxIC) was launched as a prospective multi-center registry of cases who receive medical toxicology consultations. Now, with over 100,000 cases, the Core Registry continues to address many medical toxicology research questions and has served as the foundation for multiple sub-registries, including the North American Snakebite Registry and the Medications for Opioid Use Disorder sub-registry. ToxIC also has evolved a portfolio of non-registry-based projects utilizing medical toxicology physician site principal investigators who enroll patients through emergency departments, irrespective of whether they received a medical toxicology consultation...

INTRODUCTION: Glucagon-like peptide-1 receptor agonist use has increased over the last decade for glycemic control in type 2 diabetes mellitus, cardiovascular risk reduction, and weight loss. Clinical trials indicate that gastrointestinal adverse effects are commonly experienced and severe hypoglycemia is rare; however, there is little data regarding glucagon-like peptide-1 receptor agonist in overdose. METHODS: We performed a retrospective chart review evaluating and characterizing glucagon-like peptide-1 receptor agonist exposures reported to a single poison center between 2006 and 2023...

BACKGROUND: Caustic ingestions are relatively uncommon, but remain a significant source of morbidity. Patients with caustic injury often undergo an urgent EGD, although it is not clear if an EGD is routinely needed in an asymptomatic patient. The study has two primary objectives; 1) to determine the utility of routine EGD in asymptomatic suicidal caustic ingestions; 2) to determine if asymptomatic unintentional acidic ingestions can be managed with observation alone, similar to basic ingestions...

INTRODUCTION: Synthetic cannabinoid receptor agonists (SCRAs) are associated with significant toxicity and are increasingly used in electronic vaping devices. We assessed the availability of SCRA vaping products to UK purchasers on the surface web. METHODS: An internet snapshot survey was performed between October 2022 and January 2023 on 'google.com' using the search terms "buy c-liquid vape", "buy herbal incense vape liquid", "buy cannabis vape liquid", "buy hashish vape liquid", "buy K2 vape liquid"...
