Intracranial Hemorrhage and Facial Fractures After Nose Blowing and Sternutation: A Case Report.

Introduction: Blowing the nose and sneezing are ubiquitous physiologic processes. While exceedingly rare, traumatic injuries have been described. We detail a case of spontaneous intracranial hemorrhage and orbital fractures sustained as a result of these two phenomena in an otherwise healthy adult without known risk factors for bleeding or intracranial hemorrhage.

Using Quantitative D-Dimer to Determine the Need for Pulmonary CT Angiography in COVID-19 Patients.

Introduction: COVID-19 has been frequently cited as a condition causing a pro-inflammatory state leading to hypercoagulopathy and increased risk for venous thromboembolism. This condition has thus prompted prior studies and screening models that utilize D-dimer for pulmonary embolism (PE) into question. The limited research to date has failed to provide tools or guidance regarding what COVID-19 positive patients should receive pulmonary CT angiography screening.

Ancillary Findings on CT Pulmonary Angiograms that are Negative for Pulmonary Embolism.

Context: One advantage of computed tomographic pulmonary angiograms (CTPA) is that they often show pathology in patients in whom pulmonary embolism (PE) has been excluded. In this investigation, we identified the ancillary findings on CTPAs that were negative for PE to obtain an impression of the type of findings shown.

Methods: This was a retrospective analysis of findings on CTPAs that were negative for PE obtained in nine emergency departments between January 2016 - February 2018.
