Vomiting in Kids After Head Trauma: To CT or Not to CT?
A 6-year-old male is brought to the emergency department (ED) after falling from the monkey bars at a local playground. Physical examination reveals no scalp hematoma, and the child appears alert and well oriented. You decide to observe him over the next 30 minutes hours to determine if he develops any disconcerting symptoms. After 15 minutes of observation within the ED the patient has an episode of vomiting witnessed by the nurses. The patient’s mother wants to know if this means he has failed his observation period and needs to receive a head CT. Your answer? [+]
Antidiabetic Medications: Hypoglycemic Potential in Overdose
With several new diabetes medications available, it is important to know which ones are likely to cause hypoglycemia after overdose. Based on mechanism of action and reported cases, the likelihood of hypoglycemia after overdose is listed below by drug class. 1 Keep in mind that other drugs can interact with antidiabetic medications resulting in hypoglycemia. The following table applies only to single agent ingestion/administration. [+]
PV Card: Focused Abdominal Aorta Ultrasound
In this next ultrasound installment in the PV Card series, Drs. Victoria Koskenoja, Heidi Kimberly, and Mike Stone succinctly summarize the focused abdominal aorta ultrasound to assess for an abdominal aortic aneurysm (AAA). These can serve as key reference cards when you do your next AAA scan. Don't miss the last card with tips on optimizing the view and common pitfalls.

US4TW Case: 28F with Shortness of Breath
Welcome to the inaugural post for an exciting new ultrasound-based case series called “Ultrasound For The Win!” (#US4TW). In this peer-reviewed case series, we will focus on real clinical cases where bedside ultrasound changed the management or aided in the diagnosis. In our first case, we present a 28-year-old female with shortness of breath. [+]
Small bowel obstruction: Diagnosis by ultrasonography
A 64 year old man with an extensive history of abdominal surgeries presents to the emergency department with abdominal pain and vomiting. Because you suspect a bowel obstruction, you bring an ultrasound machine to the bedside prior to the completion of any laboratory testing or other imaging. A curvilinear probe in the abdominal mode setting was used to scan in all four quadrants of the abdomen looking in both the sagittal and transverse planes. [+]
Beta Blockers vs Calcium Channel Blockers for Atrial Fibrillation Rate Control: Thinking Beyond the ED
Intravenous beta blockers and non-dihydropyridine calcium channel blockers are recommended first-line for atrial fibrillation (AF) with rapid ventricular rate (RVR) [1]. In a previous post, Bryan Hayes (@PharmERToxGuy) provided an overview of the data comparing beta blockers to calcium channel blockers for atrial fibrillation rate control in the ED. Here is part 2 of our two-part AF series. [+]
I am giving prochlorperazine. Should I give diphenhydramine too?
Prochlorperazine is a commonly used medication in EM. In certain patients prochlorperazine does wonders for migraines, and remains a great antiemetic choice for undifferentiated nausea/vomiting when ondansetron is ineffective. However, prochlorperazine has antidopinamergic activity increasing the chances of extrapyramidal symptoms (EPS), such as akathisia, dystonia, parkinsonism, and rarely tardive dyskinesia. A common practice in the ED is to give diphenhydramine with prochlorperazine to attenuate EPS. Does this really work? What is the evidence? [+]
Diagnose on Sight: Swollen Upper Extremity in a Patient with End Stage Renal Disease
Case: A 45 year old female with end-stage renal disease presents with 2 days of worsening pain, swelling, and color change of her left upper extremity. The symptoms began after her left arm arteriovenous (AV) fistula was accessed for hemodialysis. The skin is tense and a bruit is present. What is your diagnosis for this swollen upper extremity?

AIR Series: HEENT Module 2014
Welcome to the second ALiEM Approved Instructional Resources (AIR) Module! In an effort to reward our readers for the reading and learning they are already doing online, we have created an Individual Interactive Instruction (III) opportunity utilizing FOAM resources for US Emergency Medicine residents. For each module, the board curates and scores a list of blogs and podcasts. A quiz is available to complete after each module to obtain residency conference credit. Once completed, your name and institution will be logged into our private Google Drive database, which participating residency program directors can access to provide proof of completion. [+]
