An Innovative Curriculum For Teaching Transesophageal Echocardiography (TEE) to Emergency Medicine Residents.

Background: Focused transesophageal echocardiogram (TEE) can be a valuable tool for emergency physicians (EP) during cardiac arrest.

Objectives: We sought to demonstrate the ability of emergency medicine (EM) residents without prior TEE experience to perform a simulated four-view TEE following a short, flipped conference curriculum.

Methods: This was a prospective, simulation-based study where EM residents participated in the following four-view TEE curriculum: 1 h of online content reviewed prior to a 20-min in-person lecture and 30-min hands-on practice using a TEE trainer.

Characteristics of tree nut challenges in tree nut allergic and tree nut sensitized individuals.

Background: Characteristics and outcomes of tree nut (TN) oral food challenges (OFCs) in patients with TN allergy or sensitization alone are poorly studied.

Objective: To determine the relation between TN sensitization levels and OFC outcomes.

Methods: Open TN OFCs performed from 2007 through 2015 at a referral center were analyzed to compare outcome based on skin prick test (SPT) wheal size, food-specific immunoglobulin E (sIgE), peanut co-allergy, and TN sensitization only vs TN allergy with sensitization to other TNs.

The economic effect and outcome of delaying oral food challenges.

Background: Food specific IgE (sIgE) is a useful marker to assess predictability of oral food challenge (OFC) outcome. A threshold of less than 2 kUA/L for peanut, egg, and milk has been proposed as a 50% negative predictive value at which patients may pass an OFC.

Objective: To assess the economic effect and outcome of delaying OFCs.
