[10] Patients may become unable to perform activities of daily living and most require assistive devices within 5 to 10 years of symptom onset.
Polymyositis and the associated inflammatory myopathies have an associated increased risk of cancer. [3] The features they found associated with an increased risk of cancer were older age, age greater than 45, male sex, difficulty swallowing, death of skin cells, cutaneous vasculitis, rapid onset of myositis (<4 weeks), elevated creatine kinase, higher erythrocyte sedimentation rate and higher ...
The doctor assesses for muscle weakness or rashes. Another possible test is electromyography. This test involves the insertion of small needles into the patient's muscles. [4] This allows a physician to look at the muscles' responses to various electrical nerve stimuli and evaluate which muscles potentially have myositis. [4]
Inappropriate response of stem cells in the bone against the injury or inflammation causes inappropriate differentiation of fibroblasts into osteogenic cells. When a skeletal muscle is injured, inflammatory cytokines ( Bone morphogenetic protein 2 , Bone morphogenetic protein 4 , and Transforming growth factor ) are released.
Inflammatory myopathy, also known as idiopathic inflammatory myopathy (IIM), is disease featuring muscle weakness, inflammation of muscles , and in some types, muscle pain . The cause of much inflammatory myopathy is unknown ( idiopathic ), and such cases are classified according to their symptoms and signs , electromyography , MRI , and ...
