Study Type: Observational

Official Title: Studies in the Natural History and Pathogenesis of Childhood-Onset and Adult-Onset Idiopathic Inflammatory Myopathies

Brief Summary:

This study will evaluate subjects with adult- and childhood-onset myositis to learn more about their cause and the immune system changes and medical problems associated with them. Myositis is an inflammatory muscle disease that can damage muscles and other organs, resulting in significant disability.

Children or adults with polymyositis or dermatomyositis or a related condition may be evaluated under this study. Healthy children or adults will also be enrolled as "controls," for comparison of test results.

All patients will undergo a complete history (including completing some questionnaires) and physical examination, review of medical records, and blood and urine tests. Patients may then choose to participate in an additional 1- to 5-day evaluation, which will include some or all of the following diagnostic, treatment or research procedures:

  1. Standardized muscle strength testing, range of motion of joints and walking (gait) analysis by a physiotherapist; completion of a questionnaire regarding ability to perform daily tasks
  2. Skin assessment, possibly including photographs of lesions and a skin biopsy (removal of a small skin sample under local anesthetic)
  3. Magnetic resonance imaging (scans that use magnetic fields to visualize tissues) of leg muscles
  4. Swallowing studies, including a physical examination and questionnaire on swallowing ability, studies of tongue strength, and ultrasound imaging during swallowing, and possibly, a modified barium swallow
  5. Voice and speech assessment, possibly including computerized voice analysis and laryngoscopy-analysis of the larynx (voice box) using a small rigid s
