Receiver Operator Characteristic Curves explained!

Warning: statistics ahead!! Actually, this very short VODcast is designed to keep it simple and help you understand ROC curves, sensitivity, specificity, positive predictive value, negative predictive value, and prevalence. Here is the paper I use to discuss this:

Glasgow Coma Scale Motor Component (“Patient Does Not Follow Commands”) Performs Similarly to Total Glasgow Coma Scale in Predicting Severe Injury.


Synthetic cannabinoids: how science manufactured a drug epidemic and how to treat it


In this vodcast I discuss endocannabinoids, phytocannabinoids, and synthetic cannabinoids. I review the cannabinoid receptor physiology and how it leads to the  chaotic clinical course seen in synthetic cannabinoid overdoses, such as the profound hypotension and bradycardia we call the K2 Krash. Hopefully at the end of the broadcast you will have a sufficient understanding of all things cannabinoids to treat this growing epidemic. Enjoy!


Introduction to CasemasterIQ: Deliberate practice in Emergency Medicine

This is an introduction to software I developed that enables deliberate practice in emergency medicine. Studies show that deliberate practice leads to mastery.  Don’t worry though, you won’t need to spend 10,000 hours on these cases! I think that by using CasemasterIQ you will be able to perform deliberate practice, master the correct approach to clinical challenges, and greatly improve your cognitive skill set! Check it out and email me for any questions you might have!

Mindfulness in medicine: Physician heal thyself

Physicians are among the most unhappy, stressed out professionals. In fact, there is tremendous job dissatisfaction throughout the house of medicine. In this first in a series animated video cast, I describe how physicians can explore mindfulness to recognize when stressful situations are bringing out their worst traits and why that happens. I discuss the value of treating these difficult moments with kindness, curiosity, and acceptance. I believe we can use mindfulness to explore how various fears very personal to our own situation function as the subconscious engine that drives behaviors that are destructive, disruptive, and depressing. Physicians can return to a positive state of mind and the excitement of those first moments of fulfillment they felt when they started their journey in medicine if they adopt mindfulness techniques.


Journal Club Podcast for April 20

Abscesses: Lancing the myths! This podcast and the journal club answer the following questions:
Irrigate and abscess: yes or no?
Pack an abscess: yes or no?
Antibiotics for an abscess: yes or no?
Ultrasound an abscess: yes or no?
Inject lido or lido/tetra patch: which is better?
With the usual tangential flight of ideas that accompanies these ‘casts – such as what was buffered lidocaine and why don’t we bother using it anymore?

Here are the articles – at the end is the study by Jerry Hoffman (okay so it was an abstract) that showed that buffered lidocaine was not worth much to the patient.

Small study that showed most patients would not pay $2 for buffered lidocaine.  “Heating a solution of lidocaine with epinephrine reduces the pain of local injection, but buffering with bicarbonate is more effective in this regard. The value of this difference to the patient may be minimal”
