An unusual case of multiple impalement by chain-link fence posts is presented in which facial, thoracic, and abdominal injuries were sustained following a rollover motor vehicle crash. Torso impalement injuries are briefly reviewed and guidelines for the management of such injuries are described.

Case Reports
Spontaneous cervicothoracic epidural hematoma following prolonged valsalva secondary to trumpet playing.
Spontaneous spinal epidural hematoma is an uncommon clinical entity. Patients with this disease may present with devastating neurological deficits that can mimic other diseases. Emergency physicians should be familiar with this condition to assure appropriate therapy in a timely manner. A typical case of spontaneous spinal epidural hematoma is presented with review of appropriate differential diagnosis and management.

Case Reports Comparative Study
Standard 12-lead ECG versus special chest leads in the diagnosis of right ventricular myocardial infarction.
The case of a 60-year-old woman with an acute inferior transmural myocardial infarction associated with a right ventricular myocardial infarction provided an opportunity to compare the performance of the 12-lead electrocardiogram (ECG) and the right chest leads in the diagnosis of infarction of the right ventricle. While the right chest leads revealed unequivocal evidence of ischemic injury emanating from the right ventricle, the standard leads II and III showed changes compatible with inferior myocardial infarction; familiarity with vectorial interpretive concepts of ST segment deviations could provide a hint of an associated right ventricular involvement. This report is presented at a time of renewed controversy regarding the necessity of special ECG leads in the diagnosis of acute right ventricular infarction in the routine emergency department environment.

Establishing central intravenous access in the emergency department (ED) is often both crucial and difficult. In patients with nonexistant or ambiguous external anatomic landmarks, a real-time ultrasound guided approach to internal jugular vein cannulation is useful. ⋯ The use of ultrasound for establishing central venous access has never been described in an ED setting. Two such cases in which ultrasound was extremely helpful for establishing central access in an ED are reported, the techniques employed for real-time ultrasound guidance of internal jugular vein catheterization are described, and the literature that supports the use of this technique is reviewed.

A study was undertaken to evaluate the 1-year risk of cardiac death for patients with chest pain/suspected acute myocardial infarction in the emergency department (ED) and express the prognosis in a statistical model. Clinical variables and electrocardiogram were correlated to cardiac death during 1 year. Cox regression model was used to estimate the risk of death as a continuous function of a risk score and the time interval. ⋯ There were 6,794 visits by 5,303 patients followed for 1 year, during which 604 patients died. The absolute risk of cardiac death can be calculated from the independent predictors for cardiac death: age; sex; histories of diabetes mellitus, hypertension, and congestive heart failure; and symptoms, electrocardiographic pattern, and degree of suspicion of acute myocardial infarction on admission. This model allows estimation of the prognosis for every patient with chest pain/suspected acute myocardial infarction from data easily available in the ED.
