The Trouble with Swallowing: Dysphagia as the Presenting Symptom in Lateral Medullary Syndrome.
Posterior circulation strokes account for approximately one-fourth of all ischemic strokes, but are frequently misdiagnosed by emergency providers. Current standard stroke screening tools such as the National Institutes of Health Stroke Scale and the Cincinnati Prehospital Stroke Scale are weighted toward anterior circulation stroke diagnosis. Lateral medullary syndrome, a type of posterior circulation stroke, can be particularly challenging to diagnose due to nonspecific presenting symptoms, such as dysphagia. ⋯ This report describes a 65-year-old man who presented with dysphagia, dizziness, and hoarseness. An initial neurological examination did not reveal any gross deficits, and imaging to evaluate for posterior circulation stroke was not obtained. The patient presented the following day with worsening symptoms, prompting imaging that revealed a large cerebellar ischemic infarction. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although dysphagia frequently occurs in lateral medullary syndrome, it is rarely the presenting symptom in the emergency department. In patients with cerebrovascular risk factors who present with dysphagia, a complete neurological examination should be performed and noncontrast computed tomography (CT) of the head should be obtained if a neurological deficit is appreciated. Due to their poor sensitivity, CT scans can frequently miss posterior circulation strokes, therefore magnetic resonance imaging should be considered if provider suspicion remains high. Emergency providers are encouraged to have a high level of suspicion for this rare but debilitating stroke syndrome to avoid misdiagnosis and delayed care.

The novel coronavirus SARS-CoV-2 has caused a pandemic, overwhelming health care systems around the world. Hospitals around the world, including the United States, have been struggling to adapt to the influx of patients with COVID-19, the illness caused by SARS-CoV2, given limited resources and high demand for medical care. ⋯ Point-of-care ultrasound provides numerous benefits to emergency providers caring for patients with COVID-19, including decreasing resource utilization, assisting in diagnosis, guiding management of the critically ill patient, and aiding in rapid triage of patients under investigations for COVID-19.

In the prehospital setting, pit-crew models of cardiopulmonary resuscitation (CPR) have shown improvements in survival after out-of-hospital cardiac arrest (OHCA). Certain districts in North America have adopted this model, including Saskatoon, Saskatchewan, Canada. ⋯ In our study, implementation of a pit-crew CPR model was not associated with an improvement in survival to discharge after OHCA.

Human rabies can be prevented through postexposure prophylaxis (PEP). Although the case fatality rate is high, there are only one to three human cases per year in the United States. Despite the low incidence, the cost of rabies diagnostics, prevention, and control is significant. Recommendations exist regarding which patients should receive PEP, though several studies demonstrate a high frequency of unnecessary prescribing of PEP. ⋯ A pharmacist-driven protocol can beneficially influence prescribing habits after potential rabies exposure and is associated with cost savings.
