Myositis is a rarely-encountered medical condition characterized by inflammation affecting the muscles. [2] The manifestations of this condition may include skin issues, muscle weakness, and the potential involvement of other organs. [3] Additionally, systemic symptoms like weight loss, fatigue, and low-grade fever can manifest in individuals ...
Although idiopathic inflammatory myopathy (IIM) is a diagnosis of exclusion, it is often the initial misdiagnosis of several acquired non-inflammatory myopathies. [1] [9] [10] This is due to a number of factors, including: overlapping symptoms (such as muscle weakness, pain, elevated CK);
Benign acute childhood myositis (BACM) is a syndrome characterized by muscle weakness and pain in the lower limbs that develop in children after a recent viral illness. It is transient with a spontaneous clinical resolution within 1 week.
The diagnosis of PF/PM lesions depends or their presentation and, most importantly, their histopathology showing the presence of epithelioid ganglion-like cell cells. The presence of at least some of these signature cells in a lesion with an appropriate presentation in either a soft tissue or muscle tissue is considered definitive evidence that ...
Diagnosis is typically based on some combination of symptoms, blood tests, electromyography, and muscle biopsies. [3] Eighty percent of adults with adult-onset dermatomyositis have a myositis-specific antibody (MSA). [5] Sixty percent of children with juvenile dermatomyositis have a myositis-specific antibody (MSA). [6]
[1] [2] Patients observe these symptoms and seek medical advice from healthcare professionals. Because most people are not diagnostically trained or knowledgeable, they typically describe their symptoms in layman's terms, rather than using specific medical terminology. This list is not exhaustive.
Inclusion body myositis (IBM) (/ m aɪ oʊ ˈ s aɪ t ɪ s /) (sometimes called sporadic inclusion body myositis, sIBM) is the most common inflammatory muscle disease in older adults. [2] The disease is characterized by slowly progressive weakness and wasting of both proximal muscles (located on or close to the torso ) and distal muscles (close ...
The exact cause is unclear. A combination of consistent findings on physical examination, the presence of anti HMG-CoA reductase antibodies in a person with myopathy, evidence of muscle breakdown, and muscle biopsy diagnose SAAM. [3] Treatment involves stopping the associated statin medication and taking medication to suppress the immune system.
