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.

We compared high-fidelity medical simulation to short-answer written examination in the assessment of emergency medicine residents (EMR) on a month-long medical toxicology rotation. Knowledge-based assessment tools using cases of an aspirin overdose and a tricyclic antidepressant overdose were used to assess all consecutive rotating EMR (n=53). Assessment by simulation had similar accuracy and precision but higher satisfaction rates when compared to written examination.

Context: Multiple studies have concluded that urine drug screens rarely change clinical management. The rapid comprehensive urine drug screen (RCUDS) at our institution detects over 300 substances using a combination of EIA and GC/MS and typically takes 2-5 h for completion.

Objective: We sought to determine whether this RCUDS altered management in the pediatric population.

Urine drug screens are commonly used in various clinical settings and situations. Immunoassays are the most commonly available method of testing for urine drug screens in hospitals. Although convenient, immunoassays are prone to false positive and false negative results.

Intravenous fat emulsion (IFE) therapy is a novel treatment that has been used to reverse the acute toxicity of some xenobiotics with varied success. We sought to determine how US Poison Control Centers (PCCs) have incorporated IFE as a treatment strategy for poisoning. A closed-format multiple-choice survey instrument was developed, piloted, revised, and then sent electronically to every medical director of an accredited US PCC in March 2011.

Background: Chronic ethanol consumption is known to induce adaptive changes in the hippocampal glutamatergic transmission and alter NMDA receptor binding and subunit expression. Metabotropic glutamate (mGlu) receptors have been shown to function as modulators of neuronal excitability and can fine tune glutamatergic transmission. This study was aimed to determine whether chronic ethanol treatment could change the messenger RNA (mRNA) expression of mGlu receptors in the hippocampus.
