What toxin is responsible for the most serious clinical effects experienced by patients bitten by the creature in this photo?
A 62 year old female with no past medical history presented to the ED with fevers, generalized weakness, severe muscle aches, and a rash. She had returned home from the Philippines 3 days prior to evaluation. Twenty-four hours prior to arrival, the patient noticed a rash on her shins. She denied any nausea, vomiting, diarrhea, abdominal pain, chest pain, shortness of breath, cough, sore throat, dysuria, urinary frequency, headache, and neck pain. The patient was in the Philippines for a family funeral and was indoors for most of the trip. She was unsure if she was stung by any bugs or mosquitos.

Have you ever been working a shift at 3 AM and wondered, “Am I missing something? I’ll just splint and instruct the patient to follow up with their PCP in 1 week.” This is a reasonable approach, especially if you’re concerned there could be a fracture. But we can do better. Enter the “Can’t Miss” series: a series organized by body part that will help identify common and catastrophic injuries. This list is not meant to be a comprehensive review of each body part, but rather to highlight and improve your sensitivity for these potentially catastrophic injuries. Last post, we reviewed the elbow. Now, the “Can’t Miss” adult wrist injuries.

This is EMRad, a series aimed at providing “just in time” approaches to commonly ordered radiology studies in the emergency department. When applicable, it will provide pertinent measurements specific to management, and offer a framework for when to get an additional view, if appropriate. Last post, we focused on the elbow. Now: the wrist.

Welcome to Leg Day #5 of the SplintER Series. The focused history and physical ankle exam of the patient with an acute ankle injury is a crucial tool often overlooked in the Emergency Department (ED). Our hope is that after enough practice, you will be able to complete your ankle exam within 2 minutes! The key is to practice, practice, and practice some more.
