1/25. Clonal chromosomal changes in juxta-articular myxoma.cytogenetic analysis of a juxta-articular myxoma revealed two distinct cytogenetically abnormal cell populations: inv(2)(p15q36) and 7, t(8;22)(q11-12; q12-13). These clonal chromosomal changes, the first to be reported in this tumour type, suggest that at least some juxta-articular myxomas are neoplastic rather than reactive in nature.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
2/25. classification and treatment of intercondyloid fractures of the humerus.The authors describe the satisfactory results obtained in sixteen intercondyloid fractures of the humerus, thirteen of which were treated surgically. The preference for surgical treatment in such fractures is based in the assumption that, as in all articular fractures, a good functional result can only be achieved if there is the most perfect possible reconstruction of the fragments and the joint surface. A classification is therefore suggested which is based not purely on anatomical criteria, but is also related to treatment and prognosis. The slendor nature of the distal end of the humerus and the danger of metal reaction call for the use of fixation devices that are efficient but slender, such as fine screws and crossed wires. The precise method of fixation is conditioned above all by the direction of the fracture lines. More solid fixation with early mobilisation can be achieved by compression screws, and less solid fixation with longer immobilisation is achieved by fixation with crossed Kirschner wires. Consequently, the more oblique types of fracture with fragments with long beaks that allow more stable fixation with compression screws have the more favourable prognosis. In the evaluation of results, the authors emphasize the importance of using parameters which take into account the functionally useful range of joint movement.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
3/25. Peripheral joint scanning with technetium pertechnetate. Application in clinical practice.Results of a prospective study to evaluate the clinical usefulness of radioisotope joint scanning in the practice of rheumatology are reported. The radiopharmaceutical used was technetium pertechnetate, increased synovial blood flow being the main contributory factor to abnormal joint images. Strict adherence to a procedural protocol was necessary to assure reproducible images. Joint scintigraphy was performed on 56 control subjects without joint disease and 51 patients with different rheumatic disorders. There was excellent agreement between clinical examination and joint scintigraphy in all groups studied. In cases of disagreement, the joint scintigram generally was more sensitive. This high sensitivity for the detection of synovitis was accompanied by a lack of specificity, because it failed to diagnose the nature of the joint involvement. The joint scan was helpful for diagnosing early or steroid-suppressed synovitis and also for suspected nonarticular rheumatism. It aided in delineating the pattern of joint involvement. Joint scintigraphy is the only objective nontraumatic permanent record documenting joint inflammation.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
4/25. lipoma arborescens of the knee: a case report.lipoma arborescens is a rare intraarticular lesion of unknown etiology. We describe the radiographic, computerized tomographic, and magnetic resonance (MR) imaging characteristics of lipoma arborescens in a 17-year-old boy presenting with chronic painful swollen knee. Histologic examination after surgical synovectomy confirmed the diagnosis of lipoma arborescens. The fatty nature and frond-like appearance of this lesion can be demonstrated on imaging studies, especially MR imaging. Open synovectomy is curative in most cases. Although lipoma arborescens is rare, it is important to recognize and differentiate it from other synovial lesions by MR imaging.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
5/25. Chronic meningococcaemia.Chronic meningococcaemia is a rare disorder. A patient was admitted to hospital with intermittent fever and arthralgia of a migratory nature for 1 week. Maculopapular lesions were present. His temperature was 38.5 degrees C. Physical examination revealed a patient without any signs of severe illness. blood cultures grew neisseria meningitides.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
6/25. Cardiopulmonary complications in multicentric reticulohistiocytosis. Report of a case.Multicentric reticulohistiocytosis (MR) is a rare disease. Only recently was its systemic nature appreciated. It affects the skin, mucous membranes, joints, muscles, tendon sheaths, synovial membranes, bones, liver, kidney, lymph nodes, heart, and lungs. Our patient, a 50-year-old woman, had life-threatening cardiopulmonary complications of MR. The connection between the skin lesions, the arthritis, and the pathologic changes in the heart and lungs is still obscure.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
7/25. lipoma arborescens of the knee: report of a case managed by arthroscopic synovectomy.We report a case of lipoma arborescens treated with an arthroscopic procedure. lipoma arborescens is an uncommon pseudo-tumoral synovial lesion usually located in the suprapatellar pouch of the knee. This diagnosis should be considered, particularly in patients with chronic joint effusion. magnetic resonance imaging confirms the lipomatous nature of the synovial proliferation. When limited to the anterior compartment of the knee, lipoma arborescens can be treated by arthroscopic synovectomy.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
8/25. Late complications after a yersinia enterocolitica epidemic: a follow up study.Ninety four Finnish conscripts were affected by a yersinia enterocolitica epidemic in 1973. Thirteen years later 75 men completed a questionnaire about their present health. One half had no health problems, and the most common complaints in the other subjects were musculoskeletal disorders. Sixteen men wanted to be re-examined. In three cases a chronic connective tissue disease was diagnosed. Two men had ankylosing spondylitis. The most notable results of this study were (a) the fairly low number of late complications, (b) the close correlation between complications and the hla-b27 antigen, and (c) the correlation between raised yersinia antibody titres and the late complications. The nature of the primary causative agent may affect the development of late complications.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
9/25. Arthroscopic observation and treatment of synovial chondromatosis of the temporomandibular joint. Report of a case and review of the literature.Synovial chondromatosis of the TMJ is a rare disorder of unknown etiology that may be neoplastic or hyperplastic in nature. A histopathologically confirmed case, the first to be identified and treated by arthroscopy, is presented. Removal of the affected synovial tissue and of loose particles was accomplished arthroscopically, a relatively non-invasive alternative to open arthrotomy.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
10/25. Acromegalic arthropathy. Characteristics and response to therapy.Arthropathy was assessed in 19 patients with active acromegaly. Axial or peripheral arthropathy was present in 10 patients, was located most often in large joints or the lumbosacral spine, and was osteoarthritic in nature. The mean duration of acromegaly in patients with arthropathy was 21.6 years, while the mean duration in patients without arthropathy was 7.9 years. A mild-to-moderate improvement in symptoms, estimated functional ability, and crepitus occurred in 8 of 9 patients who were prospectively examined during therapy to lower production of growth hormone. We conclude that this therapy did improve the symptoms of acromegalic arthropathy. Whether objective structural improvements occur remains unclear.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
