Reversible Cerebral Vasoconstriction Syndrome (RCVS) is a rare cause of severe headache that can mimic other causes of sudden, severe headache and result in frequent emergency department (ED) visits. ⋯ Diagnosis and appropriate management of RCVS can be aided by understanding key aspects of the history and examination. The emergency clinician can then obtain indicated imaging, confirming the diagnosis and allowing for appropriate management.

Several case reports suggest that penetrating thoracic cage fractures are an important cause for hemopericardium and cardiac tamponade following blunt trauma. However, the prevalence of this mechanism of injury is not fully known, and considering this association may provide a better understanding of the utility of cardiac component of the FAST (Focused Assessment with Sonography for Trauma). ⋯ Thoracic cage fractures secondary to blunt trauma represent a significant independent risk factor for the development of a pericardial effusion. Our findings lend support for the mechanism of bony injuries causing penetrating cardiac trauma. Given these findings, and the fact that many thoracic cage fractures are detected after the initial evaluation, we support maintaining the cardiac view in the FAST examination for all blunt trauma patients.

Myocarditis following mRNA COVID-19 vaccination has recently been reported to health authorities in the United States and other countries. Cases predominately occur in young adult males within four days following the second dose of either the Moderna (mRNA-1273) or Pfizer-BioNTech (BNT162b2) vaccines. Although the number of cases reported have been small in comparison with the large number of people vaccinated, myocarditis may be a rare adverse reaction to the COVID-19 vaccination that is now only becoming apparent due to the widespread use of the vaccine. ⋯ Based on these findings, the patient was diagnosed with myocarditis. The patient had a previous infection with SARS-CoV-2 approximately two months prior to the onset of his symptoms, but since he had fully recovered before the time of his presentation to the ED, it is unlikely that the infection caused the myocarditis. To our knowledge, this is the first published case of myocarditis following BNT162b3 vaccination.

Out of hospital cardiac arrest (OHCA) patients are often transported to the closest emergency department (ED) or cardiac center for initial stabilization and may be transferred for further care. We investigated the effects of delay to transfer on in hospital mortality at a receiving facility. ⋯ Dwell time was not associated with in-hospital mortality. Rapid transport may be associated with risk of rearrest. Prospective data are needed to clarify optimal patient stabilization and transport strategies.

Carbon monoxide poisoning is a toxicological emergency that causes neurological complications. High serum neurogranin can be detected in acute or chronic conditions where brain tissue is damaged. This study aimed to investigate the diagnostic value of serum neurogranin level and its role in demonstrating neurological damage in patients admitted to the emergency department with carbon monoxide poisoning. ⋯ Serum neurogranin level may be a new diagnostic biomarker in patients admitted to the emergency department with carbon monoxide poisoning. The high serum neurogranin levels detected in patients with normal diffusion-weighted imaging after carbon monoxide poisoning suggest that there is neurological damage in these patients, even if imaging methods cannot detect it.
