To describe the use of intra-arterial tissue plasminogen activator (tPA) to treat central retinal artery occlusion (CRAO). A case and its findings were analyzed. A 45-year-old man diagnosed with a CRAO and had cerebral angiography and treatment with intra-arterial tPA.

Design: Retrospective case series and evaluation of a diagnostic test or technology.
Participants: Adult patients who presented with painless monocular vision loss and were diagnosed with a nonarteritic retinal artery occlusion.
Purpose: To evaluate medical student perceptions of a novel ophthalmology resource delivered through facilitated workshops in the core clerkship curriculum.
Methods: We created www.2020sim.
Introduction And Problem Statement: Common and potentially life-threatening neurologic conditions often present with neuro-ophthalmologic manifestations. Given the growing shortage of neurologists, and specifically neuro-ophthalmologists, it is important that students who will be at the front lines of these complaints are comfortable assessing such patients. We developed a neuro-ophthalmology learning intervention composed of an interactive workshop that discussed novel, online case-based modules.

The use of a Mobile Interventional Stroke Team (MIST) traveling to Thrombectomy Capable Stroke Centers to perform endovascular thrombectomy has been shown to be significantly faster with improved discharge outcomes, as compared with the drip-and-ship (DS) model. The effect of the MIST model stratified by time of presentation has yet to be studied.

Patients And Methods: Fifteen eyes of 15 patients presenting with acute CRAO were included in this retrospective consecutive interventional case series. Patients were excluded if treatment with IAT was not initiated within 12 hours.
Background And Purpose: Coronavirus disease 2019 (COVID-19) has been associated with an increased incidence of thrombotic events, including stroke. However, characteristics and outcomes of COVID-19 patients with stroke are not well known.
Methods: We conducted a retrospective observational study of risk factors, stroke characteristics, and short-term outcomes in a large health system in New York City.
Background And Purpose: The 2019 novel coronavirus outbreak and its associated disease (coronavirus disease 2019 [COVID-19]) have created a worldwide pandemic. Early data suggest higher rate of ischemic stroke in severe COVID-19 infection. We evaluated whether a relationship exists between emergent large vessel occlusion (ELVO) and the ongoing COVID-19 outbreak.
View Article and Find Full Text PDFCoronavirus disease 2019 (COVID-19) is a pandemic disease currently affecting millions of people worldwide. Its neurological implications are poorly understood, and further study is urgently required. A hypercoagulable state has been reported in patients with severe COVID-19, but nothing is known about coagulopathy in patients with milder disease.

Unnecessary administration of thrombolytics to potential stroke patients whose symptoms are not caused by an acute ischemic stroke-stroke mimics-may result in patient harm, although the overall risk of hemorrhagic complications among stroke mimics is low.
Case Report: We present a case of a stroke mimic patient with underlying psychiatric disease who was treated with intravenous alteplase on four separate occasions in four different emergency departments in the same city.
Tissue plasminogen activator (tPA) is administered to patients with suspected ischemic stroke to improve blood flow to the brain In rare cases, patients present with complaints of stroke symptoms that appear to be non-organic due to malingering, factitious disorder, or conversion disorder (psychogenic stroke mimics). Deciding whether or not to administer tPA to these patients can be challenging. The risk of hemorrhage after administration of tPA is low, but not zero.

After cardiac arrest, both patients were pulseless for a protracted period. Upon extubation, both developed agonal movements (gasping respiration) resembling life.

Methods: Conditioned media from human CRC epithelial cells and myofibroblasts were screened by cytokine arrays for tumorigenic factors.
Purpose: BRAF mutations occur in non-small-cell lung cancer. Therapies targeting BRAF mutant tumors have recently been identified. We undertook this study to determine the clinical characteristics of patients with lung adenocarcinomas harboring BRAF mutations.
