Educational Pearls:

  • Recent CDC statement warns against consumption of cookie dough
  • Two common ingredients can pose risk: eggs and flour

Podcast # 426: Ho Ho – Oh No!

Author: Katrina Iverson, MD

Educational Pearls:

  • The winter holiday months present a unique picture of patient presentations to the emergency department
    • Some of the unique presentations include:
    • Children falling off Santa’s lap
    • Sledding injuries
    • Falling off ladders
    • Lacerations, ingestion, and insertion of broken ornaments (pediatrics)
  • Parents tend to hurt themselves on their children’s toys

Podcast # 425: Oseltamivir Efficacy in Children

Author: Aaron Lessen, MD

Educational Pearls:

  • Recent meta-analysis reviewed efficacy oseltamivir (Tamiflu) in pediatric populations treated for influenza, showing an 18 hour reduction in duration of illness for those with laboratory confirmed influenza
  • Those with suspected influenza unsurprisingly had less effect
  • Subgroup analysis showed most benefit in those treated within the first 24 hours of symptom onset
  • Patients with confirmed influenza treated with oseltamivir had a 34% reduction in risk of otitis media

Editor’s note:  Vomiting was higher in the treatment groups; There were no significantly different outcomes in regards to other endpoints, such as lower respiratory tract infections and hospitalizations

Podcast # 424: Hunting for Measles

Author: Mike Hunt, MD

Educational Pearls:

  • Measles is highly contagious and successfully infects 90% of those at risk exposed to the virus.
  • 10 day prodrome where patients are asymptomatic.
  • 3 day period of characteristic cough, coryza, conjunctivitis, fever and Koplick spots with a maculopapular rash that moves from head through trunk
  • Infection risk extends three to four days after the onset of rash but also three to four days prior to onset.  Have fun with that.
  • A potential exposure, say in an emergency department waiting room, needs review of any exposed patient’s immunization history to contain spread

Podcast # 423: Blunt Cardiac Injuries

Author: Mike Hunt, MD

Educational Pearls:

 

  • Blunt cardiac injuries most commonly occur in motor vehicle collisions, auto-pedestrian collisions, and from sports injuries
  • The more anterior right ventricle is the most commonly injured structure
  • Look for new EKG changes such as bundle branch blocks, ST changes, or other arrhythmias
  • New EKG abnormalities should prompt consideration of further workup and admission for telemetry
  • Patients may have an elevated troponin – but it is unclear when exactly this should be drawn after the injury

Podcast # 422: ED Opioid Prescription Trends

Author: Jared Scott, MD

Educational Pearls:

 

  • From 1996 to 2012, the total quantity of opioids prescribed increased 647% for non-cancer pain
  • Office based prescriptions accounted for 84% of the total opioid prescriptions, up from 64%
  • The total share of opioids prescribed from the emergency department declined from 10% to 3.9% but
  • Total opioids prescribed from the ED still increased 219% over this same time frame

Podcast # 421: Sweet DKA Pearls

Author: Gretchen Hinson, MD

Educational Pearls:

  • Diabetic ketoacidosis patients are subject to electrolyte derangements
  • Potassium should be monitored closely:
    • K < 3.3 = Do not give insulin and replete K first
    • 3.3 < K < 5.3 = give 20-30mEq K for each L of IVF
    • K > 5.3 = delay potassium replacement
  • Adult patients are typically severely volume depleted and can require 50 cc/kg bolus or more
  • Insulin typically given in bolus of 0.1 units/kg followed by drip at 0.1 units/kg/hr

Podcast # 420: CT Contrast and the Kidneys

Author: Don Stader, MD

Educational Pearls:

 

  • Recent meta-analysis has demonstrated that there is no significant risk for kidney injury from CT contrast
  • Most kidney injury  seen after contrast CTs were due to other underlying illnesses (sepsis, hypovolemia, etc.)
  • Older contrast agents likely did have nephrotoxic effects but this appears to be a thing of the past

Podcast # 419: Etripamil

Author: Don Stader, MD

Educational Pearls:

 

  • Etripamil is an intranasal calcium channel blocker in development for use in SVT
  • A recent study showed that etripamil has an SVT conversion rate of around 80%
  • Etripamil does not have the same feeling of “impending doom” that can occur with adenosine

Editor’s note: Etripamil is still in development and these results are from a phase II clinical trial.

Podcast # 418: Vertebral Artery Dissection

Author: Don Stader, MD

Educational Pearls:

  • Vertebral artery dissection (VAD) contributes to just 2% of strokes overall but ~25% of strokes for patients < 30
  • VAD is associated with minor trauma (chiropractic manipulation, yoga), typically with neck extension and rotation.
  • VAD can cause posterior stroke symptoms (vertigo, diplopia, Horner’s Syndrome, Wallenberg Syndrome)
  • Overall a good prognosis with around 50% of patients recovering without lasting neurologic deficits.
