The best preparation for tomorrow is doing your best today. -H. Jackson Brown Jr.
Welcome back to Episode 12! This week we once again continued our theme-based review. We focused on a few high-yield bites and envenomation. This material is easy to gloss over since we do not come across it too often clinically. Not only will this prepare you at the bedside, but it will also help you pick up a few easy points on the In-Training Exam, which, by the way, is right around the corner.
* Envenomation by a Portuguese Man O’ War is treated by immediate removal of the nematocyst followed by a salt-water wash.* Black widow spiders have a red hourglass on their abdomen.* Bites from a black widow spider produce a local papule with a halo. Severe symptoms include muscle fasciculations and a peritonitic abdomen.* Brown recluse spider bites cause a papule that blisters and then necroses. Severe symptoms include renal failure, pulmonary edema, and shock.* A pit viper snake envenomation causes local swelling and oozing from the wound. Severe envenomation can cause a DIC-like coagulopathy with hemorrhagic bullae.
Now onto this week’s podcast!
