Comparative Study
Does computed tomographic scan affect diagnosis and management of patients with suspected renal colic?
Patients with renal colic commonly present to the emergency department (ED) and are usually treated with analgesics, antiemetics and hydration. Computed tomographic (CT) scan is commonly utilized in evaluating patients with suspected renal colic. ⋯ CT scan didn't change management when providers did not expect it would. This indicates that providers who are confident with the diagnosis of renal colic should consider forgoing a CT scan. CT scan did occasionally find important alternative diagnoses and should be utilized when providers are considering other concerning pathology.

Nitrous oxide myelopathy is rare in children. We report a 16-year-old girl who presented at the pediatric emergency department with progressive ascending numbness in 4 limbs for 1 week and sensory ataxia for 4 days. The patient had frequently inhaled nitrous oxide for recreation over the preceding 3 months. Her serum vitamin B12, homocysteine, and folate levels were within normal ranges. Magnetic resonance imaging of the spinal cord T2-weighted images series showed hyperintensities in the central and dorsal cervical spinal cord section over C1 to C6 and suspicious of hyperintensities in the thoracic spinal section over T7 and T8. ⋯ Myelopathy due to nitrous oxide should be considered in a differential diagnosis when adolescents develop neurologic symptoms after nitrous oxide inhalation abuse.

The hemodynamic profile of patients presenting to the emergency department (ED) with acutely decompensated heart failure (ADHF) provides the basis for initial management. We characterized the hemodynamic profiles of patients presenting to the ED with ADHF and their association with treatments and outcomes. ⋯ Of HTN ADHF patients, less than half received vasodilators, and approximately one-third did not receive diuretics, in the ED. The development of stratified protocols for therapy based on these profiles should be considered.

Randomized Controlled Trial
Topical Tetracaine Used for 24 Hours Is Safe and Rated Highly Effective by Patients for the Treatment of Pain Caused by Corneal Abrasions: A Double-blind, Randomized Clinical Trial.
The objective of this study was to test the hypothesis that topical tetracaine would be safe to use for 24 hours and would not affect corneal healing, that patients would experience more pain relief, and that patients would perceive tetracaine to be more effective than saline eye drops for the treatment of pain caused by corneal abrasions. ⋯ Topical tetracaine used for 24 hours is safe, and while there was no significant difference in patient VAS pain ratings over time, patient surveys on overall effectiveness showed that patients perceived tetracaine to be significantly more effective than saline.
