Inferior Pancreaticoduodenal Artery Pseudoaneurysm Causing Biliary Obstruction: A Case Report.

Introduction: Visceral arterial aneurysms and pseudoaneurysms are rare but dangerous pathologies, with reported incidence of 0.01-0.2% of the worldwide population, as found on autopsy.

A Case Report of Spontaneous Pneumomediastinum From an Unusual Cause: Baritone Practice.

Spontaneous pneumomediastinum (SPM) is a rare but potentially life-threatening clinical entity in which free air is introduced into the mediastinum. It most commonly presents in young males and has an incidence of approximately 0.002% of the general population.

Acute Chest Syndrome.

Audience: Emergency medicine residents and medical students on emergency medicine rotations.

Introduction: Acute chest syndrome is a life-threatening, potentially catastrophic complication of sickle cell disease.1,2 It occurs in approximately 50% of patients with sickle cell disease, with up to 13% all-cause mortality.

Refeeding Syndrome in Emergency Department Boarders: How COVID-19 Can Reshape Patient Care in the Emergency Department.

Emergency departments (EDs) in the United States are the primary drivers of hospital admissions. As the nation continues to experience unrestrained spread of the severe acute respiratory syndrome coronavirus 2, causing coronavirus disease 2019 (COVID-19), EDs, hospitals, and testing centers are overwhelmed with patients. The consequence of "boarding" admitted patients in EDs leads not only to longer ED wait times for all patients but also delays the medical practice of intensivists and internists while patients await an inpatient bed.

3rd-Degree Atrioventricular Block.

Audience: This oral boards case is appropriate for emergency medicine residents and medical students on emergency medicine rotations.

Introduction/background: Third-degree heart block (also known as complete heart block) is a cardiovascular emergency that requires prompt recognition. Complete heart block is a type of atrioventricular (AV) block whereby no atrial impulses reach the ventricular conduction system.

The revised Approved Instructional Resources score: An improved quality evaluation tool for online educational resources.

Background: Free Open-Access Medical education (FOAM) use among residents continues to rise. However, it often lacks quality assurance processes and residents receive little guidance on quality assessment. The Academic Life in Emergency Medicine Approved Instructional Resources tool (AAT) was created for FOAM appraisal by and for expert educators and has demonstrated validity in this context.

Esophageal Rupture Associated With COVID-19: A Novel Case Report.

Emergency departments (EDs) are the primary driver for hospital admissions in the United States (US), and that trend is likely to continue through the ongoing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. As the US continues to experience rampant community spread, coronavirus disease 2019 (COVID-19) will likely present in increasingly variable ways to the EDs. We present a case of Mallory-Weiss tear and esophageal perforation, which was likely caused by COVID-19 pneumonia.

Eclampsia.

Audience: Emergency medicine residents and medical students on emergency medicine rotations.

Introduction: Eclampsia is an uncommon but important life-threatening obstetrical emergency, complicating 1.5-10 deliveries per 10,000 pregnancies in resource-rich countries.

Ebola or Not? Evaluating the Ill Traveler From Ebola-Affected Countries in West Africa.

Background.  The 2014-2015 Ebola epidemic in West Africa had global impact beyond the primarily affected countries of Guinea, Liberia, and Sierra Leone. Other countries, including the United States, encountered numerous patients who arrived from highly affected countries with fever or other signs or symptoms consistent with Ebola virus disease (EVD).

Thoracic outlet syndrome: a neurological and vascular disorder.

Thoracic outlet syndrome (TOS) is a condition arising from compression of the subclavian vessels and/or brachial plexus as the structures travel from the thoracic outlet to the axilla. Despite the significant pathology associated with TOS, there remains some general disagreement among experts on the specific anatomy, etiology, and pathophysiology of the condition, presumably because of the wide variation in symptoms that manifest in presenting patients, and because of lack of a definitive gold standard for diagnosis. Symptoms associated with TOS have traditionally been divided into vascular and neurogenic categories, a distinction based on the underlying structure(s) implicated.
