Clinical Trial
The effect of real time 2-D-echocardiography on medical decision-making in the emergency department.
2-D Echocardiography (ECHO) represents an important tool for the evaluation of the Emergency Department (ED) patient with suspected cardiovascular (CV) pathology. The present study assesses the degree of effect of real time ECHO on Emergency Physician diagnosis, treatment, and disposition of CV patients and their level of confidence in these decisions. One hundred ED patients with suspected CV pathology were enrolled into this prospective, interventional study. ⋯ A significant change was seen in both a more and a less confident direction. Physicians were 3 times more confident regarding diagnosis, 7 times more confident regarding treatment, and 3 times more confident regarding disposition decision-making. Real time ECHO appears to have a significant level of impact on physician level of confidence and medical decision-making concerning patients with suspected cardiovascular pathology in the ED.

Case Reports
Traumatic retrobulbar hemorrhage: emergent decompression by lateral canthotomy and cantholysis.
Traumatic retrobulbar hemorrhage may result in acute loss of vision that is reversible when recognized and treated promptly. A case of traumatic retrobulbar hemorrhage is presented. The technique of emergent orbital decompression by lateral canthotomy and cantholysis is described. The anatomy of the lateral canthus and the surgical procedure are illustrated by gross dissection.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparative study of intra-articular lidocaine and intravenous meperidine/diazepam for shoulder dislocations.
The purpose of this study was to compare the analgesic effectiveness of intra-articular lidocaine versus intravenous meperidine and diazepam during the reduction of anterior shoulder dislocations. Patients were randomized to one of the two methods before the reduction of shoulder dislocations. Patients marked a visual analog pain scale at baseline, after anesthesia just before reduction, and at the time of discharge. ⋯ IAL was more effective than IVMD in shortening recovery time (p = 0.025). There was an indication favoring IVMD in terms of physician-perceived muscle relaxation and patient's perception of analgesia adequacy. In conclusion, although the IVMD method appears to have some clinically and statistically significant advantages, IAL possesses some favorable features that render it to be an analgesia alternative in shoulder dislocation reduction.

Bupropion is a relatively new and popular medication with seizures as its major side effect. This drug can produce seizures with an overdose. The purpose of this investigation was to determine the relative importance of this medication as the etiology of new-onset seizures relative to other drugs and new-onset seizures in general. ⋯ Sleep deprivation, previous history of attention deficit disorder and bulimia, and previous heavy alcohol use were associated in three of the patients taking bupropion who had seizures. We conclude that although drug related new-onset seizures are not a common cause of seizures overall, bupropion might be a more common cause of drug related new-onset generalized seizures presenting to the Emergency Department than previously thought, occurring in more than one-fifth of this subgroup of cases. Possibly, greater exclusion criteria are needed than currently recommended for the use of bupropion at therapeutic doses.
