International Multi-Specialty Expert Physician Preoperative Identification of Extranodal Extension n Oropharyngeal Cancer Patients using Computed Tomography: Prospective Blinded Human Inter-Observer Performance Evaluation.

Importance: Extranodal extension (pENE) is a critical prognostic factor in oropharyngeal cancer (OPC) that drives therapeutic disposition. Determination of pENE from radiological imaging has been associated with high inter-observer variability. However, the impact of clinician specialty on human observer performance of imaging-detected extranodal extension (iENE) remains poorly understood.

Heparin for Vertebral Intraluminal Thrombus Causing Retroperitoneal Hemorrhage from Occult Renal Angiomyolipoma.

Stroke is a common cause of mortality and serious long-term disability worldwide. In the acute setting, current American Heart Association/American Stroke Association guidelines do not recommend routine anticoagulation for the management of acute ischemic strokes. However, short-term use of unfractionated heparin (UFH) in select subpopulations has demonstrated improved outcomes.

Atlanto-occipital distraction injuries in survivors: craniometrics and associated ligamentous, spinal cord, and blunt cerebrovascular injury.

Purpose: Newer classification systems for upper cervical spine trauma now include ligamentous injury in addition to fracture and dislocation patterns. Assessment of associated ligamentous injury, spinal cord injury (SCI), and blunt cerebrovascular injuries (BCVI) in patients with atlanto-occipital distraction injuries (AODI) are critical for management. We aim to determine the incidence of ligamentous injury, SCI, and BCVI in patients with AODI and assess how craniometrics perform in diagnosis of AODI.
