Paucis Verbis: Lifetime attributable risk of cancer from CT

How great would it be if you could give patients concrete numbers when you are talking about cancer risk and CT? Well, Dr. Hans Rosenberg (Univ of Ottawa)  has come up with just such a table.

Using this table you can say that the risk is about “one in …”

Trick of the Trade: Fingertip injuries

FignernailGone2sm fingertip injuriesFingertips can get injured in a variety of ways such as machetes, meat grinders, and broken glass. You name it, and we’ve probably seen it. Some don’t actually need anything invasive done because the skin is basically just torn off. The wound just needs to be irrigated, explored, and then bandaged to allow for secondary wound closure.

What do you do if the finger injury keeps oozing and the finger tip is too painful for the patient to apply firm pressure? Poking the finger with 2 needles to perform a digital block seems a bit overkill.

SAEM National Meeting a success!

SAEMlogo

The national SAEM meeting in Boston just concluded and was a success. As part of the SAEM Social Media Committee, I was encouraged to see how many people were tweeting events from the meeting. Check out the tweets with the #SAEM11 hashtag.

Paucis Verbis: Pulmonary Embolism Clinical Prediction Rules

Pulmonary embolism prediction tools“Should I get a D-Dimer test or CT chest angiogram on my patient with atypical chest pain to rule-out a pulmonary embolism?” This is a common question asked by emergency physicians on a routine basis.

Here are 3 clinical prediction rules: PERC, Wells, and Simplified Geneva Score. Personally, I’ve never used the Geneva Score, but it’s worth looking at.

A WORD of CAUTION

These rules should be used with caution, because none of these scoring protocols are perfect. For instance, in a recent publication in the Journal of Thrombosis and Haemostasis, the authors found that the PERC rule does not actually safely exclude PEs.1 Big bummer for us clinicians.

Thanks to Dr. Kit Tainter (Mount Sinai PGY-4 EM resident) for coming up with the idea for this card!

Tricks of the Trade: Tea bags to the rescue

 
TeabagEyes

I have heard of using tea bags under your eyes to reduce puffiness, but to combat odors in the ED?

In my growing list of “Tricks of the Trade” tips for protecting your olfactory nerves (Antacid booties for toxic sock syndrome, aerosolized orange juice, abscess drainage using suction), I got a clinical gem from Dr. James Juarez (Rogue Valley Medical Center in Ashland, OR) after my recent Tricks of the Trade talk at High Risk EM in San Francisco.
