Angioedema and Epinephrine Causing a Stress-Induced Cardiomyopathy.

Presentations of angioedema range from mild edema to immediate life-threatening airway involvement. Management is typically straightforward and dependent on the degree of presentation. In our case, a 61-year-old female presented with angioedema requiring immediate intubation.

From Rhode Island to Colombia: Brown University Emergency Physicians Lead a Collaborative Consortium in a Post-Conflict Colombia.

Introduction: Colombia represents a country in transition, from decades of devastating civil war to a post-conflict era of peace building, to the recent management of the influx of thousands of Venezuelan migrants. Brown University, along with Colombian partners, are leading the way in an international, multi-institutional consortium with the goal of emergency medicine capacitation across Colombia. Program Implementations: Through these collaborative efforts, exchange programs for residents and faculty alike have been successfully established.

Levamisole-Adulterated Cocaine Toxicity: Would You Recognize It?

Adulteration of cocaine with levamisole is common and can induce serious medical complications. Levamisole is an antihelminthic agent originally approved as an immunomodulator in the treatment of autoimmune disorders and as a chemotherapy adjunct. It was withdrawn from the US market in 2000 but is available in veterinary medicine.

A research agenda for gender and substance use disorders in the emergency department.

For many years, gender differences have been recognized as important factors in the etiology, pathophysiology, comorbidities, and treatment needs and outcomes associated with the use of alcohol, drugs, and tobacco. However, little is known about how these gender-specific differences affect ED utilization; responses to ED-based interventions; needs for substance use treatment and barriers to accessing care among patients in the ED; or outcomes after an alcohol-, drug-, or tobacco-related visit. As part of the 2014 Academic Emergency Medicine consensus conference on "Gender-Specific Research in Emergency Care: Investigate, Understand and Translate How Gender Affects Patient Outcomes," a breakout group convened to generate a research agenda on priority questions related to substance use disorders.

Ischemic stroke presenting as fluctuating focal weakness in an otherwise healthy young man.

A 32-year-old man presented to our emergency department (ED) with no complaints after paramedics responded to a fall. Medics noted left-sided weakness on scene. Symptoms were initially absent in the ED, although later recurred, and included dramatically waxing and waning focal weakness.

Mental health and emergency medicine: a research agenda.

The burden of mental illness is profound and growing. Coupled with large gaps in extant psychiatric services, this mental health burden has often forced emergency departments (EDs) to become the de facto primary and acute care provider of mental health care in the United States. An expanded emergency medical and mental health research agenda is required to meet the need for improved education, screening, surveillance, and ED-initiated interventions for mental health problems.

Long-term behavioural and molecular alterations associated with maternal separation in rats.

In this study we addressed whether certain behavioural measures, endocrine levels and specific stress-related proteins exhibit long-term alterations in adult rats following repeated postnatal maternal separation. Rats were subjected to daily maternal separation for 15 min (HMS15) or 180 min (HMS180) from postnatal day 2-14. Adult HMS180 animals were hypoactive and had increased levels of stereotypy compared to HMS15 and normal animal facility-reared (AFR) animals.

Suppression of L-type voltage-gated calcium channel-dependent synaptic plasticity by ethanol: analysis of miniature synaptic currents and dendritic calcium transients.

Intoxicating concentrations of ethanol inhibit N-methyl-d-aspartate (NMDA) receptor-dependent long-term potentiation, an interaction thought to underlie a major component of the central nervous system actions of ethanol. Another form of synaptic potentiation involving activation of L-type dihydropyridine-sensitive voltage-gated calcium channels (VGCCs) has been described, but very little information concerning ethanol effects on VGCC-dependent synaptic potentiation is available. Here, we assessed ethanol effects on VGCC-dependent synaptic potentiation using whole cell patch-clamp recordings of alpha-amino-3-hydroxy-5-methyl-4-soxazolepropionic acid (AMPA) receptor-mediated miniature excitatory postsynaptic currents (mEPSCs) in area CA1 of the rat hippocampus.

Ifenprodil and ethanol enhance NMDA receptor-dependent long-term depression.

Long-term alterations in synaptic transmission are thought to underlie various types of alcohol-related brain disorders. While ethanol effects on synaptic potentiation are well documented, ethanol effects on synaptic depression have not been addressed. Herein, we performed experiments to assess the role of ethanol on long-term depression (LTD) formation.
