Lower Extremity Weakness in an Adolescent Female - A Rare Presentation of Ewing Sarcoma.

Background: Ewing sarcoma, a rare cause of cord compression, is predominantly of osseous origin but can also originate in soft tissues. Soft-tissue manifestations account for <15% of all Ewing sarcoma tumors, and even fewer cases of Ewing sarcoma originating in the epidural space have been documented.

Case Report: A 19-year-old female presented to the emergency department for worsening low-back pain during the previous 6 months and numbness and weakness in her legs during the prior 2 weeks.

Impact of Medical Scribes on Provider Efficiency in the Pediatric Emergency Department.

Objectives: Today's emergency department (ED) providers spend a significant amount of time on medical record documentation, decreasing clinical productivity. One proposed solution is to utilize medical scribes who assist with documentation. We hypothesized that scribes would increase provider productivity and increase provider satisfaction without affecting patient experience or nursing satisfaction.

Irx4 Marks a Multipotent, Ventricular-Specific Progenitor Cell.

While much progress has been made in the resolution of the cellular hierarchy underlying cardiogenesis, our understanding of chamber-specific myocardium differentiation remains incomplete. To better understand ventricular myocardium differentiation, we targeted the ventricle-specific gene, Irx4, in mouse embryonic stem cells to generate a reporter cell line. Using an antibiotic-selection approach, we purified Irx4 cells in vitro from differentiating embryoid bodies.
