Clinical, laboratory, and orbital imaging features of giant cell arteritis in comparison to non-arteritic anterior ischemic optic neuropath: a single center case series.

Background: Giant cell arteritis (GCA) is the most common vasculitis in patients older than 50 years and is considered a "do not miss" diagnosis. However, it remains a diagnostic challenge given overlapping clinical syndromes such as non-arteritic anterior ischemic optic neuropathy (NAION) and poorly explored imaging findings.

Materials And Methods: In this retrospective study between the time period of January 2013 and December 2021, a total of 13 consecutive patients with a pathological diagnosis of GCA and 8 patients with clinical diagnosis of NAION were isolated.

Rural Canadian emergency physician experiences using point-of-care ultrasound.

Objectives: Point-of-care ultrasound (POCUS) is a rapidly evolving and clinically significant skill set that has potential for improving patient care for the approximately 7 million Canadians living in rural and under-resourced environments. A national appraisal of rural POCUS training and utilization is needed to understand barriers to funding and training for rural emergency physicians in Canada. The primary objective of this study was to determine the current level of training and types of POCUS utilization by rural emergency physicians in Canada.

Novel Vascular Territory Mapping Algorithm as a Predictive Tool for Identification of Antegrade Flow in Middle Cerebral Artery Occlusion.

Background: Vascular territory mapping (VTM) software estimates which intracerebral vessel provides predominant arterial flow to a brain voxel. The presence of antegrade flow in the setting of acute middle cerebral artery (MCA) occlusion is associated with improved outcomes. We identify whether VTM software is a determinant of antegrade flow in patients with proximal MCA occlusion.

Increasing the Diagnostic Utility of Heparin-Induced Thrombocytopenia (HIT) Testing: An Academic Medical Center's Utilization Analysis and Intervention.

Background: Heparin-induced thrombocytopenia (HIT) is a potentially life-threatening adverse drug reaction with numerous diagnostic challenges. Diagnosis of HIT begins with 4T score clinical assessment, followed by laboratory testing for those not deemed low risk. Laboratory testing for HIT includes screening [enzyme-linked immunosorbent assay (ELISA)] and confirmatory [serotonin release assay (SRA)] assays, wherein SRA testing can be pursued following a positive ELISA result.
