Antifreeze poisoning is potentially life-threatening and often requires multiple antidotal therapies and hemodialysis. Ethylene or propylene glycol toxicity is commonly caused by antifreeze ingestion. However, ingestion of antifreeze is typically not associated with methemoglobinemia. Currently, only one other case of antifreeze ingestion causing combined ethylene glycol poisoning and methemoglobinemia has been reported. ⋯ A 56-year-old man presented after a witnessed, intentional, large-volume antifreeze ingestion. Evaluation revealed dark brown blood and significantly elevated methemoglobin and ethylene glycol levels. He was successfully treated with methylene blue, fomepizole, and hemodialysis. No other potential cause for methemoglobinemia was elucidated, and further research indicated that minor components of the specific antifreeze product served as an oxidizing agent. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case highlights the impact of minor, unreported product components that may significantly contribute to clinical toxicity, as well as the need to remain vigilant when reviewing product information and potential limitations therein.

Observational Study
First-Time Seizure Patients have High Rate of Abnormalities on Emergency Department Performed Brain Computed Tomography: A Prospective Study.
First-time seizures comprise 15% to 35% of all seizure-related complaints in the emergency department (ED). Emergent neuroimaging of first-time seizure patients is recommended by both the American Academy of Neurology and American College of Emergency Physicians. However, most of these studies are over 10 years old and included both adults and children. ⋯ This study demonstrated that 11.9% of first-time seizure patients presenting to the ED had abnormal findings on neuroimaging. Our findings support current recommendations to obtain emergent neuroimaging for adult patients with first-time seizures.

Cervical subluxation is a broad class of injuries in which there are degrees of misalignment of vertebral bodies in relationship to adjacent vertebra. Atlantoaxial rotatory subluxation (AARS) is a subtype of cervical subluxation resulting from exaggerated rotation of the C1-C2 complex. Inflammatory, infectious, post-surgical, and traumatic etiologies are recognized and well-described. AARS is predominantly seen in children and occurs rarely in adults. ⋯ We submit the case of an otherwise healthy adult male patient presenting to the emergency department with strangulation-induced C1-C2 subluxation with a rotational component that was treated at the bedside by neurosurgery with closed reduction. Why Should an Emergency Physician Be Aware of This? Clinicians must consider a broad range of serious pathologies in a patient presenting with torticollis, especially in the setting of strangulation. Although extremely rare in adults, AARS must be considered in the differential diagnosis, as early identification increases the likelihood of successful nonoperative treatment.

Physical restraints are used in the emergency department (ED) for agitated patients to prevent self-harm and protect staff. Prior studies identified associations between sociodemographic factors and ED physical restraints use. ⋯ At this institution, certain sociodemographic characteristics were associated with receiving both types of physical restraint. Emergency physicians also differed in restraint-ordering practice. Further investigation is needed to understand the influence of implicit bias on ED restraint use.
