Case Reports
Profound Symptomatic Bradycardia Requiring Transvenous Pacing After a Single Dose of Tizanidine.
We report a case of profound symptomatic bradycardia after a single dose of tizanidine. ⋯ Tizanidine should be used cautiously in elderly population and drug interactions screening should be performed.

Observational Study
The Contributions of Emergency Physicians to Out-of-hospital Cardiopulmonary Arrest: An Analysis of the National Utstein Registry Data.
Emergency physicians are likely to play an important role in the "chain of survival." The relationship between the number of emergency physicians and out-of-hospital cardiopulmonary arrest (OHCA) prognosis is not well understood. ⋯ An increased number of emergency physicians/100,000 population is likely to be associated with improved outcomes.

Differences in productivity between off-service residents rotating in the emergency department (ED) and their emergency medicine (EM) resident counterparts have never been directly quantified. ⋯ Shift cards can be used to foster motivation for off-service residents rotating in the ED, and is a simple and cost-effective method to improve system-based practices and utilization of resources.

Ultrasound (US) measurement of the optic nerve sheath diameter (ONSD) has been utilized as an indirect assessment of intracranial pressure. It is usually performed by trained ultrasonographers. ⋯ Emergency physicians were capable of accurately measuring the ONSD using bedside US. Prospective studies with a larger sample size are recommended to validate these findings.

Case Reports
An Uncommon Cause of Acute Back Pain: Spinal Subarachnoid Hemorrhage Progressing to Spinal Cord Compression.
Spinal subarachnoid hemorrhage (SSH) is an uncommon occurrence responsible for <1% of all cases of subarachnoid hemorrhage (SAH). ⋯ We present the case of a 53-year-old man who presented to the emergency department (ED) with acute onset of "tearing" back pain that began during activity, and who was diagnosed with an SSH that ultimately progressed to spinal cord compression. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although uncommon, the consequences of SSH are potentially devastating, yet reversible, making awareness of this condition critical. Several rare yet potentially devastating causes of acute back pain are deserving of consideration when approaching back pain in the ED setting; SSH is among them. Pain that is described as "tearing" or that is unresponsive to ordinary analgesic dosages should prompt strong consideration of vascular or other serious pathology, including arterial dissection or spinal cord compression.
