The Influence of Cervical Collar Immobilization on Optic Nerve Sheath Diameter.

Background: Prior research has revealed that cervical collars elevate intracranial pressure (ICP) in patients with traumatic brain injury. Two recent small studies evaluated the change in optic sheath nerve diameter (ONSD) measured by ultrasound as a proxy for ICP following cervical collar placement in healthy volunteers.

Objective: We sought to validate the finding that ONSD measured by ultrasound increases after cervical collar placement within an independent data set.

Ultrasound-guided Placement of a Foley Catheter Using a Hydrophilic Guide Wire.

Acute urinary retention is a common problem in the emergency department. Patients can present in significant distress, necessitating the placement of a urinary catheter. Foley catheter placement can be difficult to accomplish depending on the etiology of the retention and the degree of the obstruction.

Eosinophilic meningitis: what's the "diff"?

We report a case of a 22-year-old man who presented to the emergency department (ED) with altered mental status and was diagnosed with eosinophilic meningitis due to Angiostrongylus cantonensis (AC) acquired in the United States after exposure to snails.

Pediatric ultrasound: applications in the emergency department.

Bedside ultrasound (US) was introduced to the emergency department more than 20 years ago. Since this time, many new applications have evolved to aid the emergency physician in diagnostic, procedural, and therapeutic interventions and the scope of bedside ultrasound continues to grow. Many US scanning techniques easily translate from adult applications to the pediatric population.
