FOAM Impact: The Influence of Open-access Medical Education on Practice Uptake.

Objectives: The FOAM Impact study sought to examine baseline rates of intravenous (IV) lidocaine usage for the treatment of renal colic and to compare rates of use between FOAM utilizers and nonutilizers. We sought to measure the effect of FOAM resources on clinical practice by timing the release of FOAM content with publication of the LIDOKET trial.

Methods: A cross-sectional before-and-after survey was conducted and disseminated on two social media platforms.

Informed consent for invasive procedures in the emergency department.

Background: Informed consent for procedures in the emergency department (ED) challenges practitioners to navigate complex ethical and medical ambiguities. A patient's altered mental status or emergent medical problem does not negate the importance of his or her participation in the decision-making process but, rather, necessitates a nuanced assessment of the situation to determine the appropriate level of participation. Given the complexities involved with informed consent for procedures in the ED, it is important to understand the experience of key stakeholders involved.

A Young Patient with Painful Penile Lesions.

Chancroid is a rare infection in the United States and many other developed countries. Infrequently identified as a cause of genital ulcer disease, chancroid's atypical presentation has only been reported in approximately 20 cases annually in the United States since 2011. Infection with the causative organism, Haemophilus ducreyi, leads to an erythematous papule that rapidly evolves into a pustule.

A Case of Lactation Anaphylaxis.

We describe the case of a patient who presented multiple times to the emergency department (ED) with recurrent episodes of anaphylaxis in the immediate postpartum period. It was initially thought to be idiopathic in nature on previous visits, but was ultimately diagnosed as lactation anaphylaxis and successfully managed. The diagnosis was suspected when the detailed history revealed recurrent allergic symptoms with each episode of breastfeeding.

A Case of Thiazide-induced Hypokalemic Paralysis.

We describe the case of a patient presenting with odd neurologic symptoms initially thought to represent somatization who was found to have critical hypokalemia manifesting as hypokalemic non-periodic paralysis. It was determined that the patient had baseline hypokalemia as a function of alcohol abuse, exacerbated by self overmedication with hydrochlorothiazide for elevated blood pressure readings at home. The diagnosis was suspected when an electrocardiogram was obtained demonstrating a pseudo-prolonged QT interval with ST depression, consistent with T-U wave fusion and a QU interval with an absent T wave.

Evidence-Informed Practice: Diagnostic Questions in Urinary Tract Infections in the Elderly.

Introduction: Routine interventions in the practice of medicine often lack definitive evidence or are based on evidence that is either not high quality or of only modest-to-marginal effect sizes. An abnormal urinalysis in an elderly patient presenting to the emergency department (ED) with non-specific symptoms represents one condition that requires an evidence-informed approach to diagnosis and management of either asymptomatic bacteriuria or urinary tract infection (UTI). The emergency provider often will not have access to urine cultures, and the risks associated with antibiotic use in the elderly are not without potentially significant side effects.

Search Engine Queries for Pediatric Fever During "Cold and Flu" Season.

Introduction Pediatric fever is the most common chief complaint in patients under 15 years old. The objective of this paper is to characterize public search trends for pediatric fever in the United States using Google search engine queries. Methods and materials A cross-sectional survey of Google Trends searches for "toddler fever" was conducted from October 2018 to January 2019 during "cold and flu" season.

Public interest in gun control in the USA.

To characterise public interest in gun control in the USA using internet search queries, we undertook a cross-sectional study of the relative popularity Google Trends searchers for 'Gun Control', 'Second Amendment', 'National Rifle Association' and 'Mass Shooting' from May 2015 to December 2018. 740 weeks of data were queried. Graphed data revealed nine major inflection points.

Examination of EMS Decision Making in Determining Suitability of Patient Diversion to Urgent Care Centers.

Widespread use of Emergency Medicine Services (EMS) for non-emergency care has increased recently, causing overcrowding of the Emergency Department (ED). The increased availability of urgent care centers (UCCs), with their ability to see large numbers of unscheduled patients with more acute presentations, may offer a viable option for many EMS systems to divert non-emergent cases. Using a survey-based study combined with retrospective chart review, EMS provider ability to determine patient suitability for diversion to UCCs was assessed.

Financial relationships with industry among guideline authors for the management of acute ischemic stroke.

Objective: To characterize the prevalence of industry relationships among authors of acute ischemic stroke (AIS) guidelines and its association with graded evidence.

Methods: A cross-sectional study of five policy papers on AIS published by the American Heart Association (AHA)/American Stroke Association (ASA), American Academy of Emergency Physicians (AAEM), and American College of Emergency Physicians (ACEP). Financial conflicts of interest (FCOI) data were obtained using the Open Payments Database for the years 2013 through 2017.

Temporary Memory Steal: Transient Global Amnesia Secondary to Nephrolithiasis.

Transient global amnesia (TGA) is typified by an abrupt and transient anterograde amnesia, "with repetitive questioning and often variable retrograde amnesia persisting up to 24 hours." A 54-year-old male presented to our emergency department with paroxysms of left-sided flank pain, suggestive of renal colic. Computed tomography (CT) of the abdomen/pelvis revealed a three-millimeter left ureterovesicular-junction calculus.

Managing Shoulder Injuries in the Emergency Department: Fracture, Dislocation, and Overuse.

The complex structures of the shoulder can be injured by fracture, dislocation, and overuse, and correctly identifying and classifying injury is essential to avoiding pain, disability, and life- and limb-threatening complications. This issue presents a systematic approach to classifying shoulder injuries based on the mechanism of injury and clinical presentation, choosing appropriate imaging, and determining the best strategies for treatment, including reduction, surgical consultation, or outpatient referral. Newer recommendations on intra-articular versus intravenous analgesia are presented to increase patient comfort and improve reduction outcomes.

Refractory Ventricular Fibrillation Successfully Cardioverted With Dual Sequential Defibrillation.

Background: Current guidelines for the treatment of adult patients in cardiac arrest are supplied by the American Heart Association through basic life support and advanced cardiovascular life support (ACLS) provider courses. When treatments defined by the ACLS guidelines are unsuccessful in terminating a lethal dysrhythmia, the use of alternative strategies may prove useful. In this case, two defibrillators were used to deliver a greater than normal energy waveform over an extended time interval to return a patient to a normal sinus rhythm.
