North American musculoskeletal ultrasound scanning protocol of the shoulder, elbow, wrist, and hand: update of a Delphi Consensus Study.

Introduction/objectives: There has been an increase in the proficiency and utilization of ultrasound among North American rheumatologists over the past decade. This study aims to create an updated upper extremity scanning protocol to inform ultrasound curriculum development for the American College of Rheumatology affiliated fellowship programs and guide clinical practice patterns in North America.

Method: Three Delphi survey rounds were used to reach consensus on tiered-mastery designations for scan views of the shoulder, elbow, wrist, and hand joints.

Malignancy and idiopathic inflammatory myopathies.

Association between idiopathic inflammatory myopathies (IIMs) and malignancy is well known and has been extensively reported in the literature. However, in the recent years, several new studies were published allowing us to better understand the clinical characteristics and pathophysiology of cancer-associated IIMs. We conducted a literature review of cancer-associated IIMs focusing on new data that was published in the recent years.
