REBEL EM has primarily been a clinical blog focusing on critical appraisal of research, but now we are proud to introduce

REBEL Core

, an initiative to improve discussion of core content in emergency medicine/critical care. Free Open Access Medical Education (FOAMed) has long been dedicated to discussing current literature to shorten knowledge translation. However, if all you use is FOAMed, then you will have “swiss cheese knowledge”, due to the lack of having foundational knowledge. The entire breadth of emergency medicine is not currently covered by FOAMed with a disproportionate representation of critical care topics (i.e. ECG, Ultrasound, Resuscitation, Procedures). REBEL Core will continue to discuss the foundational knowledge necessary in all aspects of emergency care.

Take Home Points
  • Measles is highly infective: One infected person can infect approximately 10-20 unvaccinated people
  • 2 doses of MMR is 97% protective
  • Unvaccinated people can acquire measles from travel to endemic areas with low vaccination rates
  • There is a large amount of misinformation on the internet
  • Misinformation uses fear based messaging and the power of story
  • The evidence is overwhelming > 23,000,000 patients showing no evidence of any link between autism and MMR
  • Anecdotes are not evidence but vulnerable patients may be more susceptible to story then statistics
  • We should add anecdote as a tool to counsel patients

Background: Spontaneous coronary artery dissection (SCAD), once thought of as a rare “zebra” diagnosis that was universally fatal, is now being increasingly recognized as a cause of acute coronary syndrome (ACS), particularly in women due to increased vigilance, greater utilization of coronary angiography and advanced imaging. Despite these advances, SCAD still remains one of the most enigmatic syndromes in cardiology. It carries a high misdiagnosis and mistreatment rate with lack of consensus on investigation or treatment. Here we review the salient features of SCAD to increase awareness of this disease entity and further our understanding of this unique disease process.

Take Home Points
  • Trauma resulting in a retrobulbar hemorrhage can lead to orbital compartment syndrome which is a vision threatening injury
  • Diagnosis is made clinically based on the presence of an afferent pupillary defect, vision loss and an intraocular pressure > 40 mm Hg
  • Treatment is with a lateral canthotomy - a simple but mentally daunting procedure

Take Home Points
  • 100k people in US have sickle cell, the majority will at some point develop acute chest syndrome (ACS)
  • The mortality rate per episode is 3-9%, similar to those of STEMI
  • ACS is a syndrome - CXR infiltrate + respiratory symptoms
  • Treat it aggressively and early (antibiotics, respiratory support)
  • If you’re considering exchange transfusion - get hematology onboard quickly

Take Home Points

  • Wernicke encephalopathy is characterized by ataxia, altered mental status and ophthalmoplegia but patients are unlikely to have all these components
  • Suspect Wernicke encephalopathy in any patient that is at risk of malnutrition or malabsorption and has any one of the classic symptoms
  • Prophylactic administration of thiamine 100 mg IV/IM to at risk patients can prevent development of the disease
  • Once Wernicke encephalopathy has developed, it must be treated with high-dose, IV thiamine
