Botulism due to Drug Use

Timothy Hoffman, MD^* and Jennifer Yee, DO^*

ABSTRACT: Audience: This scenario was developed to educate emergency medicine residents on the diagnosis and management of wound botulism secondary to injection drug use. Introduction: Botulism is a relatively rare cause of respiratory failure and descending weakness in the United States, caused by prevention of presynaptic acetylcholine release at the neuromuscular junction. This presentation has several mimics, including myasthenia gravis

Electrocardiogram Abnormalities Following Diphenhydramine Ingestion: A Case Report

Patrick Bruss, MD^*, Christine Bowman, MD^* and Teagan Carroll, BS^*

DOI: https://doi.org/10.21980/J85H1P Issue 8:1 No ratings yet.

The blue arrow points to one of the terminal R waves in aVR, and the green arrow points to one of the large S waves in lead I, indicating right axis deviation. These findings are pathognomonic for sodium channel blockade. Due to the specific ECG findings and knowledge of diphenhydramine overdose, it was evident that these ECG findings were due to a cardiac sodium channel blockade. Sodium channels are essential within myocardial tissue to ensure the rapid upstroke of cardiac action potential, as well as rapid impulse conduction throughout cardiac tissue. Therefore, sodium channel blockers tend to exhibit significant dysrhythmic properties due to severe conduction disturbances.2 The blockage of the cardiac sodium channels appears as terminal R waves in aVR as well as terminal S waves in lead I due to delaying, and possibly blocking, the electrical conduction pathway of the heart. The orange arrows show resolution of terminal R wave in aVR and terminal S wave in lead I, after administration of sodium bicarbonate.
