Loperamide is an over-the-counter antidiarrheal with μ-opioid agonist activity. Central nervous system opioid effects are not observed after therapeutic oral dosing because of poor bioavailability and minimal central nervous system penetration. ⋯ Ventricular dysrhythmias and prolongation of the QRS duration and QTc interval have been reported after oral loperamide abuse. We describe 2 fatalities in the setting of significantly elevated loperamide concentrations.

Loperamide abuse has been increasing in the United States as a potential alternative to manage opioid withdrawal symptoms or to achieve euphoric effects of opioid use. In June 2016, the Food and Drug Administration warned health care providers and the general public about potential serious adverse outcomes, including cardiac dysrhythmias and death. The purpose of this study is to determine recent trends in intentional loperamide abuse and misuse, reported clinical effects and management, and medical outcomes as reported to poison centers across the United States. ⋯ Loperamide abuse and misuse are projected to increase in the absence of any methods to reduce exposure or curb abuse. Health care providers should consider the potential for loperamide toxicity when managing patients with opioidlike toxicity.

Randomized Controlled Trial Comparative Study
Comparison of Ventilation With One-Handed Mask Seal With an Intraoral Mask Versus Conventional Cuffed Face Mask in a Cadaver Model: A Randomized Crossover Trial.
We compare received minute volume with an intraoral mask versus conventional cuffed face mask among medics obtaining a 1-handed mask seal on a cadaver model. ⋯ The intraoral mask resulted in greater received minute volume received compared with conventional cuffed face mask during ventilation with a 1-handed mask seal in a cadaver model. The intraoral mask may prove a useful airway adjunct for ventilation.

Paradoxical vocal fold motion disorder, also commonly termed vocal cord dysfunction, is a poorly understood cause of acute upper airway obstruction. Patients with paradoxical vocal fold motion frequently present to the emergency department (ED) with acute respiratory distress and stridor. ⋯ Although long-term management of paradoxical vocal fold motion is well described, there is a paucity of information about acute evaluation and management. This article aims to summarize the ED presentation and management of paradoxical vocal fold motion.

Making Sense of a Negative Clinical Trial Result: A Bayesian Analysis of a Clinical Trial of Lorazepam and Diazepam for Pediatric Status Epilepticus.
We demonstrate the application of a Bayesian approach to a recent negative clinical trial result. A Bayesian analysis of such a trial can provide a more useful interpretation of results and can incorporate previous evidence. ⋯ Because Bayesian analysis estimates the probability of one or more hypotheses, such an approach can provide more useful information about the meaning of the results of a negative trial outcome. In the case of pediatric status epilepticus, it is highly likely that lorazepam is noninferior and practically equivalent to diazepam.
