As physicians attempt to "Choose Wisely" and decrease ionizing radiation, the use of Magnetic Resonance Imaging (MRI) has increased. While MRI does not expose patients to ionizing radiation, it does expose patients to specific risks, such as thermal burns. Unfortunately, obese patients are at the highest risk for MRI-related thermal burns. ⋯ The burn required debridement twice at the nearest burn center and healed slowly thereafter. Emergency physicians should be aware of the risks of MRI so they can counsel patients prior to diagnostic MRI and adequately evaluate patients with complaints after MRI. Furthermore, patients with MRI-related burns may rarely present with delayed, occult deep-tissue involvement requiring burn center evaluation and treatment.

Electrocardiographically occult occlusive myocardial infarction (OOMI), defined as coronary artery occlusion requiring revascularization without ST-segment elevation on electrocardiogram (ECG), is associated with delayed diagnosis resulting in higher morbidity. Left ventricular (LV) wall motion abnormalities (WMA) appreciated on echocardiography can expedite OOMI diagnosis. We sought to determine whether point-of-care ultrasound (PoCUS) demonstrating WMA expedites revascularization time when performed on emergency department patients being evaluated for OOMI. ⋯ Cardiac PoCUS may identify OOMI earlier than standard evaluation and may expedite definitive management.

Case Reports
Factor-guided diagnosis of coagulopathy associated with coumarin-contaminated synthetic cannabinoids: A case report.
Contamination of synthetic cannabinoids with toxic coumarin derivatives known as superwarfarins can induce a persistent coagulopathy. In comparison to warfarin, these derivatives have prolonged half-lives and laboratory assays for detection are not readily available in clinical practice. To our knowledge, factor-guided diagnosis of coagulopathy secondary to coumarin-contaminated synthetic cannabinoids has not been described previously. ⋯ Toxic coumarin derivative assays are not immediately available for reference. Given the patient's confirmed synthetic cannabinoid consumption and the possibility of coagulopathy from coumarin-contamination, factor levels served as a guide for diagnosis and treatment prior to the confirmatory assay. Obtaining factor levels in patients with an unexplained coagulopathy and suspected cannabis or synthetic cannabinoid use may aid clinicians in a more prompt diagnosis and treatment.

Letter Case Reports
Amphetamine toxicity masked by concomitant γ-hydroxybutyrate (GHB) ingestion.
We report a case of a young male with amphetamine toxicity initially obscured by concomitant use of gamma-hydroxybutyrate (GHB), and the sympathomimetic symptoms emerged after GHB's effects receded. A 24-year-old unconscious man presented to emergency department showed the following vital signs upon admission: blood pressure 136/58 mmHg; heart rate 79 bpm; SpO2 87% under ambient air; body temperature 36.1 °C; Glasgow Coma Scale score 3. The pupils were not dilated. ⋯ The patient improved later and was extubated at 4 days after the mitigation of pneumonia and discharged uneventfully 8 days later. In our patient, amphetamine intoxication was initially masked by concomitant use of GHB but appeared as GHB's effect attenuated. We wish to remind clinicians of variable clinical presentations of polydrug abuse.

Given the importance of understanding methodical reporting and statistical terminology in ensuring evidence-based decision-making, physicians should possess statistical literacy. The purpose of this study was to distinguish statistical terminology commonly used in emergency medicine methods and describe changes in statistical methods from 2011 to 2021. ⋯ By understanding common statistical terms and trends over time, educational efforts can be targeted to consumers of EM literature. Additionally, this work provides evidence suggesting an overall improvement in processes in statistical methodology, enhancing the quality of research outputs and ultimately allowing better clinical decision-making.
