Infections following rattlesnake envenomation and use of antibiotics.

Background: There are 7000-8000 venomous snake bites annually in the USA. Antibiotics are commonly administered to bite victims because infection is difficult to differentiate from local tissue injury following envenomation.

Methods: The Arizona Poison and Drug Information Center (APDIC) in Tucson oversees antivenom administration for 14 Arizona counties.

Fasciotomy following North American pit viper envenomation in Texas 2004-2021.

Introduction: North American pit viper envenomation occurs over 4,000 times annually in the United States, with polyvalent Fab antivenom being the primary treatment. Fasciotomy is occasionally performed due to concerns about compartment syndrome. We utilized our direct access to Texas Poison Center Network data to create a new snakebite abstraction form and database on relevant available information between 2004 and 2021 and to identify, describe, and estimate the incidence of fasciotomy following pit viper envenomation in Texas.

Energy drink exposures reported to Texas poison centers: Analysis of adverse incidents in relation to total sales, 2010-2014.

The ill-defined term "energy drink" includes a disparate group of products (beverages, shots, concentrates, and workout powders) having large differences in caffeine content and concentration and intended use. Hence, inaccurate conclusions may be drawn when describing adverse events associated with "energy drinks". The FDA is considering new regulation of these products but product specificity is needed to evaluate safety.

Retrospective review of SGLT2 inhibitor exposures reported to 13 poison centers.

Background: SGLT2 inhibitors are a new class of oral antidiabetics prescribed in the United States since 2013. They act by inhibiting reabsorption of glucose in the proximal convoluted tubule of the kidney, allowing excess glucose to be excreted. Little has been reported regarding effects of non-therapeutic exposure to this class of medication.

Intentional Misuse and Abuse of Loperamide: A New Look at a Drug with "Low Abuse Potential".

Background: Despite its opioid properties, loperamide has long been thought to have low abuse potential due to its poor absorption from the gastrointestinal tract and limited potential to cross the blood-brain barrier. A recent patient reportedly taking loperamide to avoid heroin withdrawal symptoms, at doses approximately 100 times those recommended, directed our attention to this issue.

Objectives: 1) Investigate number of cases of intentional loperamide abuse and misuse reported to poison centers between 2009 and 2015; 2) Compile reports of clinical effects of loperamide abuse; and 3) Search for evidence of increasing Internet interest in the central opioid effects of loperamide.

Asphyxiants.

Asphyxiants deprive the body of oxygen. Simple asphyxiants displace oxygen from the lungs, whereas systemic asphyxiants interfere with transport of oxygen by hemoglobin or with mitochondrial oxidative phosphorylation. Asphyxiants may be gases, liquids, or solids, or their metabolites.
