Paucis Verbis: Clostridium Difficile

I just finished taking the 2011 LLSA exam to remain eligible for recertification. The only good thing about this test is that it gives me interesting topics for my Paucis Verbis cards.

Here’s a card on a disease process that is becoming increasingly prevalent — Clostridium difficile. This is a summary based on the 2010 guidelines by Society for Healthcare Epidemiology of America (SHEA) and the Infectious Diseases Society of America (IDSA).

Because healthcare workers are often the culprit for transmitting C. difficile to other patients, be sure you wash your hands with soap and water really well. Wear gloves. Be aware that alcohol-based hand rubs (eg. hand sanitizers) are ineffective in killing C. difficile spores.

Trick of the Trade: Cunningham maneuver for shoulder dislocation

We commonly see patients with shoulder dislocations in the Emergency Department. There are a myriad of approaches in relocating the joint, which includes scapular rotation, Snowbird, and Kocher maneuvers.

I recently stumbled upon the Cunningham technique after hearing about it from Dr. Graham Walker (of MDCalc fame) on TheCentralLine.org.

Trick of the Trade: I need more lidocaine but I have sterile gloves on!

How often has this happened to you —

You are in the middle of a sterile procedure (chest tube, suturing, central venous line, lumbar puncture) and you realize that you need more lidocaine to provide better topical anesthesia. You don’t have any more in your kit and you are alone in the room with the patient.

“Uh, can someone help me out there?”

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

Fingertips 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.

Paucis Verbis: Pulmonary Embolism Clinical Prediction Rules

“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!

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.
