From LifeInTheFastLane.com‘s illustrious Dr. Mike Cadogan. These were the slides from his Social Media in Medicine talk at the recent USC Essentials Conference. It’s time more physicians get involved and join the conversations that are taking place on social media. Join now.
Scalp lacerations are one of the most common injuries which present to the Emergency Department. Applying a dry bandage over the staples or sutures can be a challenge because the tape just has nothing to adhere to.
We reviewed the use of tubular cotton gauze to create a beanie hat, but what should you do if you can’t find any tubular gauze? Ever since I wrote about the beanie hat trick, people in the ED have been using the tubular gauze more and we’re always out of stock whenever I look for it!
What is your diagnostic approach to the acutely vertiginous patient?
The bottom-line question is: Is the cause peripheral or central in etiology?
In this great 2011 systematic review article in CMAJ on Acute Vestibular Syndrome (AVS), the authors review how (un)predictive elements of the history and physical exam are. By definition of AVS, symptoms must be continuous for at least 24 hours and have no focal neurologic deficits.
Frighteningly, the authors report many of the signs and symptoms (type of dizziness, hearing loss, patterns of nystagmus, Hallpike-Dix) are not as predictive as we classically are taught!
The take home point is to learn and incorporate the 3-part HINTS exam into your diagnostic approach (see bottom box on card). It is reported to be as good as a diffusion-weighted MRI for diagnosing a posterior stroke. The steps are:

There is a helpful 10-minute video showing normal and abnormal HINT findings:

Thanks to Dr. Brian Resler (UCSF-SFGH EM resident) for giving me the heads up about this at Followup Conference!
Patients can become extremely diaphoretic with high fevers or if under the influence of PCP or a stimulant. Slippery, sweaty skin can pose a problem when securing peripheral IV’s. Adhesive tapes that are typically designed for securing these IV’s often slip off… immediately followed by the IV falling out.
How can you secure the IV … without using staples and sutures?
Have you noticed that on “Who Wants To Be A Millionaire”, asking the audience as a lifeline almost always results in the right answer (over 90% of the time)?
Dr. David Thorisson (Lund University, Scandinavia) recently approached me with a novel idea of doing the same for Emergency Medicine questions. These questions are currently posted to a public Google Docs document, which allows anyone to post and answer questions.
