1/51. orbital myositis and rheumatoid arthritis: case report.orbital myositis implies orbital inflammation confined to one or more of the extraocular muscles. The acute form responds well to high doses of oral corticosteroids tapered gradually, but it may recur or become chronic. We describe a 38 years old female who has been suffering from rheumatoid arthritis for six years. She developed diplopia as a result of a paralysis of the right and left rectus medialis muscle. MRI showed inflammatory process and thickness of the referred muscles. The patient had a total recovery with oral use of 80 mg methylprednisolone daily. Two months after the first episode she developed a bilateral ophthalmoplegy. The patient improved with oral use of steroids the second time, but a paresis of the left rectus lateralis muscle remained. From the 156 cases we reviewed only three have been related to rheumatic diseases and none has been previously related to rheumatoid arthritis.- - - - - - - - - - ranking = 1keywords = myositis (Clic here for more details about this article) |
2/51. Seropositive rheumatoid arthritis with dermatomyositis sine myositis, angioimmunoblastic lymphadenopathy with dysproteinemia-type T cell lymphoma, and B cell lymphoma of the oropharynx.Angioimmunoblastic lymphadenopathy with dysproteinemia (AILD) is a rare lymphoproliferative disorder that often progresses to high grade T cell lymphoma. We describe a 63-year-old woman with longstanding seropositive rheumatoid arthritis who developed fever, cutaneous findings of dermatomyositis, a diffuse pruritic maculopapular rash, enlarged lymph nodes, polyclonal elevated serum gammaglobulins, and an IgG lambda paraprotein. Lymph node biopsies yielded tissue with characteristic changes of AILD and T cell lymphoma. Interleukin 6 (IL-6) was present during the early, active phase of disease, and circulating IL-6 and IL-2 were detected one month before tumor recurrence. Two years after AILD and T cell lymphoma were diagnosed, she developed a B cell lymphoma that involved the oropharynx.- - - - - - - - - - ranking = 1.8keywords = myositis (Clic here for more details about this article) |
3/51. association of polymyositis with rheumatoid arthritis.The association of polymyositis (PM) and rheumatoid arthritis (RA) is described in a 40-year-old female Mexican patient who was studied for a long period of time. The characteristic changes of PM that preceded the onset of RA for 7 years included proximal symmetrical muscle weakness, increased creatine kinase activity, and distinctive electromyography and muscle biopsy results. The occurrence of RA during the final 4 years of the 11-year period was characterized by long-lasting deforming and symmetric polyarthritis, high positive rheumatoid factor, subcutaneous nodules, and erosive joint changes. Through observation, myopathic changes other than those from PM were excluded. Joint changes other than from RA were also ruled out. A review of the literature revealed few specific reports of the coexistence of both diseases.- - - - - - - - - - ranking = 21.799214192984keywords = polymyositis, myositis (Clic here for more details about this article) |
4/51. Cutaneous lymphoma associated with Epstein-Barr virus infection in 2 patients treated with methotrexate.Whether patients with rheumatoid arthritis (RA) have an increased risk of developing non-Hodgkin lymphoma is controversial, and opinions differ on the possible role of methotrexate in the occurrence of lymphomas in patients with RA. We report 1 T-cell lymphoma and 1 B-cell lymphoma restricted to the skin associated with Epstein-Barr virus infection that healed completely and spontaneously after discontinuation of methotrexate in a man with RA and a woman with dermatomyositis. Cutaneous infiltrating cells were infected by a replicative form of Epstein-Barr virus. After discontinuation of methotrexate, the cutaneous lesions disappeared completely in 15 days without recurrence. Discontinuation of methotrexate is necessary in patients with RA or dermatomyositis who have a lymphoproliferative disorder, and a follow-up period of several weeks should be observed before specific therapy is initiated.- - - - - - - - - - ranking = 0.4keywords = myositis (Clic here for more details about this article) |
5/51. Anterior tibial compartment syndrome due to the pyomyositis in a patient with rheumatoid arthritis. A case report.Anterior tibial compartment syndrome was developed due to pyomyositis in a 33-year-old male patient with rheumatoid arthritis while receiving steroid therapy during the follow-up period. The preoperative physical examination, laboratory findings, MRI images, intraoperative observation and postoperative histopathological examinations confirmed the association with pyomyositis. The surgical drainage and antibiotic treatment were effective, and in the follow-up period, neuromuscular dysfunctions disappeared completely within 6 months. The patient has been asymptomatic for 4 years of follow-up. To date, anterior tibial compartment syndrome due to pyomyositis in a case with rheumatoid arthritis has not been reported.- - - - - - - - - - ranking = 1.4keywords = myositis (Clic here for more details about this article) |
6/51. Antiphospholipid and antisynthetase syndrome in a patient with polymyositis-rheumatoid arthritis overlap.Idiopathic inflammatory myopathies, mainly polymyositis (PM) may occur in the course of several autoimmune diseases. The overlapping forms of myositis, when the patient also meets the criteria for rheumatoid arthritis (RA), affect 3%-5% of myositis patients [1]. To the best of our knowledge this is the first report on the overlapping form of RA, antiphospholipid syndrome (APS) and the serological subgroup of PM, the antisynthetase syndrome (ASS).- - - - - - - - - - ranking = 22.199214192984keywords = polymyositis, myositis (Clic here for more details about this article) |
7/51. Involvement of mitochondria in myasthenia gravis complicated with dermatomyositis and rheumatoid arthritis: a case report.We report a 57-year-old male with myasthenia gravis complicated with dermatomyositis and rheumatoid arthritis without evidence of thymoma. He showed prominent muscle wasting and weakness in the four extremities and trunk in addition to swallowing disturbance. He showed intolerance to exercise on a bicycle ergometer, and muscle biopsy specimens demonstrated ragged-red fibers. An anti-acetylcholine receptor (AChR) antibody was detected in his serum but no anti-mitochondrial M2 component antibody was found. In contrast, results of immunohistochemical study indicated that his serum sample reacted to muscle mitochondria as well as AChR. These results indicate the presence of an unidentified anti-mitochondrial antibody that may be involved in the development of mitochondrial dysfunction in skeletal muscle of the present patient.- - - - - - - - - - ranking = 1keywords = myositis (Clic here for more details about this article) |
8/51. Severe proximal myopathy and mononeuritis multiplex in rheumatoid arthritis: manifestations of rheumatoid vasculitis.Vascular injury is considered to be a key finding in the pathogenesis of rheumatoid arthritis (RA). Manifestations are varied depending on the vessel size and the organ system involved. Vasculitis leading to symptomatic inflammatory myositis is a rare complication of RA. We describe a 62-year-old man with seropositive erosive RA of 1-year duration, who presented with severe proximal weakness and mononeuritis multiplex. His joint disease was clinically mild at the time of presentation. creatine kinase was normal and the electromyogram did not suggest myopathy. However, muscle biopsy revealed extensive small vessel vasculitis and severe inflammatory myositis. This report emphasizes the importance of fully evaluating patients with RA who present with proximal myopathy. The myopathy in our patient was not related to active joint disease, disuse atrophy, or complication of therapy. rheumatoid vasculitis leading to myositis is a rare and not well-recognized complication of RA for which aggressive immunosuppressive therapy is warranted.- - - - - - - - - - ranking = 0.6keywords = myositis (Clic here for more details about this article) |
9/51. erythema elevatum diutinum in the setting of connective tissue disease and chronic bacterial infection.erythema elevatum diutinum (EED) is a rare and chronic cutaneous leukocytoclastic vasculitis. It is predominantly seen on the extensor surfaces of the extremities. Although a specific cause is largely unknown, EED has been noted to occur in association with a wide variety of diseases. A 28-year-old man with systemic lupus erythematosus (SLE) and a 53-year-old woman with an overlap syndrome of rheumatoid arthritis and polymyositis are presented. Both patients developed EED in the setting of chronic recurrent bacterial infections. patients with a connective tissue disease are at increased risk for such infections secondary to immunosuppression, either from the disease itself or secondary to immunosuppressive therapy. EED has been independently reported to occur in the setting of connective tissue disease as well as in the setting of chronic infection. Our patients had both of these underlying conditions, which are known to predispose patients to immune complex-mediated vasculitides, in this case EED. One patient's EED responded to treatment of the SLE and the other improved, as has been previously reported with dapsone.- - - - - - - - - - ranking = 4.3598428385968keywords = polymyositis, myositis (Clic here for more details about this article) |
10/51. Development of polymyositis after long-standing rheumatoid arthritis.Rheumatoid arthritis (RA) and polymyositis (PM) are distinct clinical syndromes. The concurrent diagnoses of RA and PM in the same patient are rare. We describe a patient who developed outright PM after 16 years of well established RA, review the literature, and highlight the need to consider a broad base of differentials including PM in the diagnosis of muscle weakness in RA.- - - - - - - - - - ranking = 21.799214192984keywords = polymyositis, myositis (Clic here for more details about this article) |
