Learning Objectives

Upon completion of this Cyberounds®, you should be able to:

  • Distinguish the different forms of myositis based on pattern of weakness, EMG findings, MRI findings and muscle histopathology;

  • List the most common myositis-associated and specific antibodies in polymyositis, dermatomyositis, immune mediated necrotizing myopathy and inclusion body myositis;

  • Recognize that a statin can trigger an immune mediated necrotizing myopathy;

  • Describe the autoantibodies that can characterize specific subgroups of myositis and reveal a specific clinical phenotype associated with the myositis-specific or associated antibody.
