There is no universal agreement on the definition of anaphylaxis or the criteria for diagnosis. In July 2005, the National Institute of Allergy and Infectious Disease and Food Allergy and Anaphylaxis Network convened a second meeting on anaphylaxis, which included representatives from 16 different organizations or government bodies, including(More)
BACKGROUND The authors describe the epidemiology and clinical course of older persons examined in emergency departments (EDs) for abdominal pain. METHODS This was a prospective, multicenter, observational study of older persons (>or=60 years) examined in participating EDs for nontraumatic abdominal pain. Medical records were reviewed for demographics, ED(More)
STUDY OBJECTIVE To determine the efficacy of flexion-extension (F/E) cervical-spine radiographs in detecting acute cervical-spine instability in emergency patients. DESIGN We retrospectively reviewed the charts of 141 consecutive trauma patients who had F/E views performed after a routine cervical-spine series (three views) was obtained in the emergency(More)
STUDY OBJECTIVES This study tested the hypothesis that serial creatine phosphokinase (CK)-MB sampling in the emergency department can identify acute myocardial infarction (AMI) in patients presenting to the ED with chest pain and nondiagnostic ECGs. DESIGN Patients more than 30 years old who were evaluated initially in the ED and hospitalized for chest(More)
The objectives of this study were to determine the prevalence of use of abdominal computed tomography (CT) in older ED patients with acute nontraumatic abdominal pain, describe the most common diagnostic CT findings, and determine the proportion of diagnostic CT results. This was a prospective, observational, multicenter study of 337 patients 60 years or(More)
PURPOSE To compare accelerational forces to the head in high school-level football, hockey, and soccer athletes. METHODS Acceleration of impact was measured within the helmet of high school hockey and football players during actual game play. A triaxial accelerometer was placed at the vertex of the helmet immediately adjacent to the players head. Peak(More)
STUDY OBJECTIVE This study examines whether serum levels of glial fibrillary acidic protein breakdown products (GFAP-BDP) are elevated in patients with mild and moderate traumatic brain injury compared with controls and whether they are associated with traumatic intracranial lesions on computed tomography (CT) scan (positive CT result) and with having a(More)
Several recent reports suggest that emergency physicians do not use adequate analgesia for patients with acutely painful conditions in the emergency department (ED). To quantify the extent of this problem, we retrospectively studied 401 patients who were treated for acute fracture over a 17-day period in eight area-wide emergency departments. Patient age,(More)
OBJECTIVES (1) Determine if older patients with abdominal pain who receive emergency department (ED) abdominal CT have changes in diagnosis and/or disposition more often than similar patients without CT; (2) compare physician confidence in diagnosis and disposition for patients with versus without CT; (3) document factors that most influence physician's(More)
