Iatrogenic Vertebral Artery Dissection with Posterior Fossa and Lateral Medullary Stroke After Uncomplicated Cervical Nerve Ablation.

BACKGROUND: A cervical radiofrequency ablation is a procedure that can be performed to treat arthritis-related pain in the neck and upper back. There have been no large studies reporting complications after this procedure. We report a case of a 55-year-old woman with iatrogenic vertebral artery dissection of C3-C4 with segmental occlusion leading to a posterior fossa stroke and lateral medullary stroke after a high-grade cervical nerve ablation. CASE REPORT: A 55-year-old woman presented to the Emergency Department with vomiting, neck pain, temperature changes, dizziness, and dysarthria after undergoing C2-C3, C4-C5 nerve ablation 30 min prior to arrival. The patient was found to have a vertebral artery dissection with posterior fossa and lateral medullary stroke. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Vertebral artery dissection and subsequent stroke should be considered with recent cervical facet joint injections, such as intra-articular facet joint injections, medial branch blocks, or medial branch radiofrequency nerve ablation. The case we report shows devastating outcomes that can result from what many consider a relatively simple procedure.

A Profile of Orthopedic Education in Emergency Medicine Residency Programs in the United States.

Introduction Emergency medicine (EM) residents throughout the United States are required to become skilled at performing a robust list of select orthopedic procedures, as well as learn how to diagnose and manage patients with musculoskeletal complaints. However, EM residency programs vary significantly in how they teach orthopedics and the content they cover. The purpose of this study was to profile the orthopedic education received by emergency medicine residents in United States residency programs. Methods We developed a survey based on accreditation requirements and The Model of the Clinical Practice of Emergency Medicine. The survey was designed to gather detailed information about the orthopedic education provided to EM residents. The survey was sent to EM program directors or their designees at all 263 accredited EM residency programs across the United States between October 2020 to January 2021. Results We attained a 34.6% (91 of 260) adjusted response rate with adequate representation of relevant program characteristics such as region, accreditation status, program length, size, and setting. Most (63.7%) responding programs required an orthopedics rotation during the intern year. These required orthopedic rotations were primarily four weeks in duration. The most common methods for teaching orthopedic topics included didactics (97.8%), procedures on live patients under supervision (73.3%), and assigned reading materials in textbooks or manuals (68.9%). Conclusion The orthopedic education received by EM residents in the United States is strikingly variable, with residency programs having to develop custom curricula to teach orthopedics content based on the resources available to them. Future efforts should be directed toward creating a universal curriculum that addresses accreditation and EM practice standards.

Characterization of Electronic Health Record Documentation Shortcuts: Does the use of dotphrases increase efficiency in the Emergency Department?

The problem of clinical documentation burden is ever-growing. Electronic documentation tools such as "dotphrases" were invented to help with the documentation burden. Despite the ubiquity of these tools, they are understudied. We present work on the usage of dotphrases within the emergency department. We find that dotphrases are most often used by medical scribes, they significantly increase note length, and are completely unstandardized as to their naming conventions, content, and usage. We find that there is inconsistent usage across and within providers and that there is much duplication in the dotphrase content. We also show that dotphrases have no effect on the time to complete and cosign a note. Finally, we demonstrate that even when accounting for patient complexity upon presentation, note authorship, and note length - notes with higher dotphrase usage are billed at higher billing levels.

A Walk in the Park: A Case of Babesiosis in the South Bronx.

Babesiosis, mainly endemic within the Northeastern and upper Midwestern regions of the United States, is a zoonotic disease that invades and lyses red blood cells, which can result in hemolytic anemia. Its decreased incidence in comparison to Lyme disease is often attributed to the greater asymptomatic infection proportion and insufficient physician awareness or suspicion of this disease. Here we describe a case of undifferentiated febrile illness with hemolytic anemia that yielded the diagnosis of babesiosis.

Nano- and sub-micron porous polyelectrolyte multilayer assemblies: biomimetic surfaces for human corneal epithelial cells.

In vivo, corneal epithelial cells adhere on basement membranes that exhibit porosity on the nanoscale with the diameters of pores and fibers ranging from 20 to 200 nm. Polyelectrolyte multilayers with porosity ranging from the nano to the microscale were assembled to mimic the pore sizes of corneal membranes in vivo. The average pore diameter was found to be 100 nm and 600 nm for the nanoporous and sub-micron porous films respectively. In this study, a purely physical feature, specifically, porosity, provided cues to human corneal epithelial cells. Porous surfaces that exhibited either 100 nm or 600 nm pore diameters supported corneal cell adhesion, however, nanoscale porosity significantly enhanced corneal epithelial cellular response. Corneal epithelial cell proliferation and migration speeds were significantly higher on nanoporous topographies. The actin cytoskeletal organization was well defined and vinculin focal adhesions were found in cells presented with a nanoscale environment. These trends prevailed for fibronectin-coated surfaces as well suggesting that for human corneal epithelial cells, the physical environment plays a defining role in guiding cell behavior.
