Reperfusion therapy for acute myocardial infarction (AMI) is indicated in the presence of ST elevation (STE) and ischemic symptoms. Previous MI may present with persistent STE or "left ventricular aneurysm" (LVA) morphology that mimics AMI. Hypothesis A high ratio of T amplitude to QRS amplitude best distinguishes AMI from LVA. ⋯ T amplitude/QRS amplitude ratio best distinguishes aAMI from LVA in ECGs that meet STE criteria for reperfusion therapy. A high ratio is associated with an AMI.

We hypothesized that critically ill patients who remain in the ED for more than 24 hours experience worse outcomes and longer lengths of stay than those transferred to the medical intensive care unit (MICU) within 24 hours. ⋯ These data suggest that outcomes of critically ill patients transferred from the ED to our MICU within 24 hours were not better than those who remained in the ED for longer durations. Larger studies are required to examine this hypothesis.

L-Carnitine is a carnitine replacement that has been used in carnitine deficiency states. We conducted a review of patients with acute valproate (VPA) poisoning that had an elevated ammonia level and received L-carnitine to address safety. ⋯ Two hundred fifty-one L-carnitine doses were not associated with adverse or toxic effects in our VPA toxic patients.

We present the case of a child with abdominal cramping found to have radiopaque matter in his gastrointestinal tract on plain radiography. The parents denied ingestion of a foreign substance but specific questioning revealed a visit for dental care the previous day. This may serve to illustrate the benefits of taking a careful goal-directed history as opposed to the often recommended open-ended approach.

Foot conditions are frequently seen in the emergency department. In many cases, although weight bearing is painful, it is not precluded, per se. When a soft dressing does not provide sufficient support, a below knee walking cast may be applied. ⋯ It is designed and molded to fit like a slipper. The plaster slipper has distinct advantages in that it is comfortable, lighter for the patient, and avoids the problem of ankle stiffness. We believe that this option is underused in the emergency setting.
