Atraumatic Infected Septal Hematoma in a Pediatric Patient.

Case Presentation: We present a case of a 10-year-old male who developed an atraumatic, nasal septal hematoma with abscess following several days of rhinorrhea and cough. His chief complaint to the emergency department was a two-day history of nasal swelling and discomfort, associated with difficulty breathing through his nose. The patient was well-appearing with swelling and tenderness along the external nasal ridge and nasal septal swelling that occluded both nares.

Spontaneous Aortic Rupture: A Case Report.

Introduction: Acute aortic syndrome (AAS) includes the disease processes of aortic dissection, penetrating atherosclerotic ulcer, and intramural hematoma. This case demonstrates an atypical presentation of the disease and offers approaches to potentially prevent missed diagnoses.

Case Report: An 87-year-old female with hypertension and Alzheimer's dementia presented to the emergency department with stable vital signs and a chief complaint of throat pain.

The Feasibility of Virtual Reality and Student-Led Simulation Training as Methods of Lumbar Puncture Instruction.

Background: There is limited data assessing simulation and virtual reality training as a standardized tool in medical education. This feasibility study aimed to evaluate the effectiveness of virtual reality training and a student-led simulation module in preparing medical students to perform a lumbar puncture.

Methods: Twenty-five medical students completed a pre-intervention survey, and a baseline video recorded lumbar puncture procedure on a task trainer.

Treatment of COVID-19: Perspective on Convalescent Plasma Transfusion.

The novel coronavirus (COVID-19) has continued its global spread since the first documented case in late 2019 in Wuhan, China. With over 10 million cases and 500 thousand deaths reported worldwide, the need for an effective treatment regimen is evident. Historically, convalescent plasma (CP) has been utilized in the treatment of viral respiratory pathogens.

BDNF and TrkB Mediate the Improvement from Chronic Stress-induced Spatial Memory Deficits and CA3 Dendritic Retraction.

The brain is capable of improving from a chronically stressed state. The hippocampus in particular appears to "recover" from chronic stress-induced morphological and functional deficits following a post-stress rest period of several weeks. We previously found that hippocampal brain-derived neurotrophic factor (BDNF) was necessary for spatial ability to improve following a post-stress rest period.
