Naloxone has been proven to reduce the incident of death in acute opioid overdoses. So why aren’t we using it more often?

Our ongoing intern report series is the product of first-year EM residents at UT Southwestern exploring clinical questions they have found to be particularly intriguing. For med students & junior residents – if you haven’t encountered these issues yet, you will!

Influenza is spread primarily through large respiratory droplets or contamination of surfaces. About 4 days after exposure patients will typically start to develop an abrupt onset of fever, headache, myalgias or dry cough—generally this presentation will be considered an uncomplicated influenza illness. Symptoms usually resolve after 3-7 days from onset. Patients can have a more complicated course if they have primary influenza pneumonia, exacerbation of underlying medical conditions like COPD, or secondary bacterial pneumonia (Strep pneumoniae, Staph aureus, community-acquired MRSA, Haemophilus influenza are the more common pathogens).

There is not a validated and widely used decision rule to help distinguish influenza from other viral pathogens based on signs and symptoms. We do know that there is some seasonal variance with influenza being more common in winter months. We also have laboratory tests like respiratory panels to screen for influenza. However, the poor sensitivity and uncertain utility of these tests makes their value in the typical uncomplicated influenza presentation questionable. Treatment recommendations, supported by the CDC, IDSA, and WHO have come under recent scrutiny—we should ALL be familiar with the recent data on influenza treatment. […]
