Prior studies addressing the incidence of acute myocardial infarction (AMI) in patients with cocaine-associated chest pain have found divergent results. Previous prospective studies, which found approximately a 6% incidence of AMI, have been criticized for selection bias. This study sought to determine the rate of AMI in patients with cocaine-associated chest pain. ⋯ The incidence of AMI was 6% in patients with cocaine-associated chest pain. This result is identical to that found in prior prospective studies.

Randomized Controlled Trial Clinical Trial
EMCyberSchool: an evaluation of computer-assisted instruction on the Internet.
To test the hypothesis that integration of the EMCyberSchool, a computer-assisted instruction (CAI) tool available on the Internet, into the curriculum of a senior medical student subinternship in emergency medicine (EM) would improve exam scores and course satisfaction. ⋯ Although desired, it remains unclear whether CAI on the Internet is a useful adjunct for teaching EM to medical students.

To provide a descriptive analysis of emergency department (ED) presentations and management of orthotopic liver transplant (OLT) patients. ⋯ Serious illnesses with nonspecific presentations were frequently encountered in this study population. These factors resulted in a majority of the patients' undergoing extensive diagnostic evaluations and being hospitalized.

Resuscitation studies of hypertonic saline using controlled and uncontrolled hemorrhage models yield conflicting results with regard to efficacy. These disparate results reflect the use of models and resuscitation regimens that are not comparable between studies. This study evaluated the effects of comparable and clinically relevant resuscitation regimens of 7.5% sodium chloride/6% dextran 70 (HSD) and 0.9% sodium chloride (NS) in a near-fatal uncontrolled hemorrhage model. ⋯ In this model of severe uncontrolled hemorrhage, resuscitation with HSD or NS, administered in volumes that provided equivalent sodium loads at similar rates, had similar effects on mortality, hemodynamic parameters, and hemorrhage from the injury site.
