| 6272421 | Radionuclide salivary gland imaging. | 1981 Oct | Salivary gland imaging with 99mTc as pertechnetate provides functional information concerning trapping and excretion of the parotid and submandibular glands. Anatomic information gained often adds little to clinical evaluation. On the other hand, functional information may detect subclinical involvement, which correlates well with biopsy of the minor labial salivary glands. Salivary gland abnormalities in systemic disease such as sarcoidosis, rheumatoid arthritis, lupus erythematosus, and other collagenvascular disorders may be detected before they result in the clinical manifestaions of Sjögren's syndrome. Such glands, after initially demonstrating increased trapping in the acute phase, tend to have decreased trapping and failure to discharge pertechnetate in response to an appropriate physiologic stimulus. Increased uptake of gallium-67 citrate often accompanies these findings. Inflammatory parotitis can be suspected when increased perfusion is evident on radionuclide angiography with any agent. The ability of the salivary gland image to detect and categorize mass lesions, which result in focal areas of diminished activity such as tumors, cysts, and most other masses, is disappointing, while its ability to detect and categorize Warthin's tumor, which concentrates pertechnetate, is much more valuable, although not specific. | |
| 7222123 | Lymphocytotoxic antibody in Sjögren's syndrome. | 1980 Jul | The autoimmune mechanism in Sjögren's syndrome (SjS) and the close association of this syndrome with systemic lupus erythematosus (SLE) have been suggested in several reports. Although the pathological significances of lymphocytotoxic antibody is obscure, possible roles of this antibody in the pathogenesis of autoimmunity have been speculated. The purposes of the present study were to demonstrate lymphocytotoxic antibody in sera of patients with SjS, and then to analyse various correlations of this antibody with clinical parameters of SjS. We detected cold-reactive lymphocytotoxic antibody not only in most (86.4%) of the patients with SLE, but also in many patients with SjS (51.6%; excluding SjS patients with SLE), rheumatoid arthritis (RA; 31.6%) and myasthenia gravis (MG; 36,4%), which are considered to be autoimmune diseases. On the other hand, lymphocytotoxic antibody was detected in only one (5.6%) of eighteen healthy persons. We also confirmed that the cold-reactive lymphocytotoxic antibody detected in SLE is 2-mercaptoethanol sensitive and T-lymphocytotoxic antibody. Frequent demonstration (50%) of this antibody even in SjS patients without any associated diseases supports the immunological basis of SjS as well as virological participation in SjS. Although this antibody did not significantly correlate with most of the clinical parameters in SjS patients, this antibody may become a hallmark as one of immunological abnormalities in SjS, even though it was produced by non-specific lymphocyte activation. | |
| 1086656 | Effect of penicillamine treatment on immune complexes in two cases of seropositive juvenil | 1975 Oct | A correlation has previously been observed between the presence of enhancing complexes and cutaneous vasculitis in rheumatoid arthritis. Two parients with seropositive juvenile rheumatoid arthritis are described in whom enhancing complexes were detected before the appearance of cutaneous vasculitis. Their contrasting response to penicillamine is discussed in relation to the role of of rheumatoid factor and antinuclear antibodies. | |
| 141862 | [Allergen testing in juvenile rheumatoid arthritis]. | 1976 | 79 children with classical collagenoses, streptococcaldiseases, arthralgia of unclear genesis and infection arthritis as well as juvenile rheumatoid arthritis and 25 normal children were submitted to an intracutaneous allergentest with various collecting extracts (legumens and cereals, house allergens, vegetables). Positive reactions to cereals in a high percentage were observed only in patients with juvenile rheumatoid arthritis and fewer also in children with unclear arthralgia and infection arthritis. | |
| 53963 | [The spontaneous NBT-test in granulocytes of patients with juvenile rheumatoid arthritis]. | 1975 Sep | 30 patients with definite seronegative juvenile rheumatoid arthritis and 3 patients with tendosynovitis and unclear arthralgia respectively were examined by the nitroblue tetrazolium (NBT) test (46 tests). A positive result could be obtained in 72 per cent of the examinations. Patients with a joint manifestation of juvenile rheumatoid arthritis showed relatively more positive results than patients with Morbus Wissler and the transition forms of juvenile rheumatoid arthritis. Tendosynovitis and unclear arthralgia were negative in the NBT test. The NBT test is not useful for the differentiation of bacterial-septic and rheumatoid-inflammatory joint diseases. | |
| 6288055 | Frequencies of Epstein-Barr virus-inducible IgM anti-IgG B lymphocytes in normal children | 1982 Aug | The relative frequencies of IgM antiIgG autoantibody (rheumatoid factor) producing cells induced by the polyclonal B cell activator Epstein-Barr virus were measured in peripheral blood lymphocyte cultures of normal children and patients with juvenile rheumatoid arthritis. The frequencies of rheumatoid factor precursor B cells in normal children were lower than adults, but higher than neonates. The frequency increased with the age of the donor. In seronegative children with the systemic-onset or pauciarticular-onset types of juvenile rheumatoid arthritis, the number of IgM antiIgG inducible B cells was not significantly different (P greater than 0.05) from age-matched controls. Patients with seropositive juvenile rheumatoid arthritis or seropositive adult rheumatoid arthritis had significantly higher IgM antiIgG precursor cell frequencies than age-matched normal subjects (P less than 0.01 and P less than 0.02, respectively). In contrast, the patients with seronegative polyarticular-onset juvenile rheumatoid arthritis had an average precursor frequency significantly lower than normal age-matched controls (P less than 0.05), analogous to results previously noted in adult seronegative rheumatoid arthritis. Thus, both children and adults with seronegative polyarticular rheumatoid arthritis had a deficiency in B cells that produce IgM antiIgG and that are induced by Epstein-Barr virus. This distinguished them from seropositive juvenile rheumatoid arthritis and rheumatoid arthritis patients, normal subjects, and patients with the pauciarticular-onset and systemic-onset types of seronegative juvenile rheumatoid arthritis. | |
| 6980582 | Juvenile rheumatoid arthritis. | 1982 Aug | Juvenile rheumatoid arthritis, the most common connective tissue disease occurring during childhood, is characterized by chronic arthritis and may be associated with disability and blindness. The presentation, laboratory findings and prognosis of the disease differ significantly from those of adult rheumatoid arthritis. Current classification includes systemic, pauciarticular and polyarticular types, each having different therapeutic and prognostic implications. | |
| 6236018 | Papular mucinosis, destructive arthropathy, median neuropathy, and sicca complex. | 1983 Sep | A patient with papular mucinosis (scleromyxedema) developed an erosive seronegative rheumatoid-like arthropathy, carpal tunnel syndrome, sicca complex, and marked increase in TG(OKT8) suppressor/cytotoxic circulating T-cells akin to that reported in scleroderma. Sclerodactyly, acrolysis and stiff digits were striking but other features of scleroderma, i.e., Raynaud's and esophageal hypoperistalsis, were absent. The diagnosis of papular mucinosis, a pseudoscleroderma syndrome, should be considered in a patient with atypical arthritis, median neuropathy, myopathy, and/or sclerodactyly and a papular lichenoid dermatopathy. Skin mucin stain and the demonstration of the distinct serum paraprotein (PM-spike) are confirmatory. We stress the salient diagnostic clinical features of the leonine-like facies of papular mucinosis. | |
| 7028379 | Pulmonary manifestations of juvenile rheumatoid arthritis. A report of eight cases and rev | 1980 Sep | Pleuropulmonary disease was seen in 4 per cent of patients with juvenile rheumatoid arthritis. Roentgenographic abnormalities seen in association with juvenile rheumatoid arthritis include: transient pneumonitis, interstitial reticular and nodular infiltrates, pleural and pericardial effusions, and patchy pleural infiltrates. Pathologic abnormalities seen in association with juvenile rheumatoid arthritis include pulmonary hemosiderosis, lymphoid follicular bronchiolitis, and lymphocytic interstitial pneumonitis. Patients with juvenile rheumatoid arthritis and pleural disease recover fully. In children with parenchymal disease, residual abnormalities include roentgenographic evidence of interstitial fibrosis and minimal abnormalities of pulmonary function. | |
| 649229 | Alterations in macroscopically intact skin of children with juvenile rheumatoid arthritis. | 1978 Mar | Punch biopsies of macroscopic-intact skin were performed on 75 children with rheumatoid arthritis, aged 4--14 years. There was no significant correlation between the morphologic alterations and the sex and age of the children or the duration of the disease, but there was a positive relationship with the degree of activity of the rheumatoid process. It appears that punch biopsy of the skin in children with juvenile rheumatoid arthritis can facilitate determination of alterations of the connective tissue if the data obtained are regularly correlated with clinical and laboratory findings. In such a way, the results can reflect the effects of treatment, as well as the evolution and prognosis of the juvenile rheumatoid arthritis. | |
| 6401995 | Quantitation and detection of isotypes of anti-SS-B antibodies by ELISA and Farr assays us | 1983 Feb | Affinity purified SS-B was characterized as a protein with immunoreactive polypeptides of 40K and 29K. A modified Farr assay and an enzyme linked immunosorbent assay (ELISA) were 100- to 1,000-fold more sensitive than immunodiffusion and showed an association with the systemic manifestations of primary sicca syndrome and Sjögren's syndrome with systemic lupus erythematosus. The ELISA was sufficiently sensitive to detect class specific antibodies in saliva and lymphocyte culture supernatants. | |
| 714494 | Secondary amyloidosis complicating rheumatoid arthritis; report of a case in an eight-year | 1978 Jul | Secondary amyloidosis can complicate any long-standing suppurative infection, such as tuberculosis, osteomyelitis and disorders of connective tissue, i.e., the so-called "collagen diseases". Rheumatoid arthritis is known to be a notable precursor of amyloidosis. The fact that a long-standing process is often necessary to produce the changes in the ground substance, makes Juvenile Rheumatoid Arthritis (J R A) an interesting challenge to that hypothesis. The decreasing incidence of secondary amyloidosis, complicating rheumatoid arthritis, is attributed to better management of patients and the use of more effective anti-inflammatory therapy. | |
| 371938 | A review of upper-gastrointestinal effects of the newer nonsteroidal antiinflammatory agen | 1979 Jan | Newer nonsteroidal antiinflammatory agents (NSAI's) such as ibuprofen, neproxen, fenoprofen, and tolmetin have broadened the therapeutic choice and increased the chances of providing optimum arthritis control, but require careful assessment of the possibilities for unwanted drug effects when long-term therapy is required. A review of the literature on the gastrointestinal effects of the promising newer NSAIs, as compared with the older agents, aspirin, indomethacin, and phenylbutazone, is presented, highlighting animal toxicology and human adverse reaction surveillance data and the evidence for various suggested pathophysiological mechanisms. | |
| 6566360 | Juvenile rheumatoid arthritis. | 1984 Jun | The nature and treatment of the three major types of juvenile rheumatoid arthritis--systemic, polyarticular, and pauciarticular--are presented. | |
| 6709317 | Acquired Brown's syndrome in children with juvenile rheumatoid arthritis. | 1984 Jan | Two children with systemic juvenile rheumatoid arthritis developed the features of Brown's syndrome coincident with an increase in disease activity. While acquired Brown's syndrome is known to occur in adults with both classical adult rheumatoid arthritis and persistent polyarticular juvenile rheumatoid arthritis, this is the first report of such an occurrence in childhood. The mechanism is likely to be an inflammatory mass which restricts the passage of the superior oblique tendon through the trochlea. | |
| 1206668 | Size distribution of lymphocytes in juvenile rheumatoid arthritis. | 1975 Dec | The diameters of circulating peripheral lymphocytes were measured in 28 children with juvenile rheumatoid arthritis. These were compared with lymphocyte measurements in 68 normal children, 19 children with asthma, and 12 children with cystic fibrosis. The average diameter of lymphocytes in normal children was found to be 11.2 microns. In contrast, the average diameter of lymphocytes in juvenile rheumatoid arthritis was 12.7 microns (P less than 0.0001). There were more lymphocytes with a diameter of 13 to 15 microns in children with juvenile rheumatoid arthritis than in normal children. | |
| 7072494 | Amyloidosis associated with juvenile rheumatoid arthritis. | 1982 Jan | Clinical and pathological findings are reported in a Japanese girl who died of secondary amyloidosis associated with juvenile rheumatoid arthritis two years after the onset of symptoms. The patient had intermittent high fever, rheumatoid rash, polyarthralgia, and hepatosplenomegaly. The joints showed the typical histologic changes of juvenile rheumatoid arthritis. Amyloid deposition was found in various tissues; however, remarkable deposition of amyloid was observed in the gastrointestinal tract, especially in the ileum. The amyloid protein in this patient was identified as protein AA using the methods of potassium permanganate treatment and the peroxidase-antiperoxidase unlabeled antibody technique. | |
| 6287090 | [Superoxide-dismutase and superoxide-radical-release in rheumatoid arthritis (author's tra | 1982 Jun 1 | Polymorphonuclear leukocytes (PMNs) release superoxide anion (O-2) when they are exposed to a phagocytic stimulus. Intracellularly the copper-containing enzyme superoxide dismutase (SOD) protects against the toxic effects of O-2. To investigate the role of O-2 and SOD in the inflammatory process we determined the O-2 release and SOD content in PMNs. In PMNs of children with rheumatoid arthritis the SOD activity was diminished compared to healthy controls. Upon stimulation with opsonized zymosan PMNs obtained from children with rheumatoid arthritis generated greater amounts of superoxide anion than control cells. The "SOD deficiency" in PMNs of children with rheumatoid arthritis may promote this extreme release of the toxic superoxide radical inducing the damage of the connective tissue. The involvement of superoxide dismutase and superoxide anion in inflammatory process may induce further studies, leading hopefully to an appropriate understanding or even to new principles in the treatment of the rheumatoid arthritis. | |
| 191230 | Daily fluctuations in the plasma cortisol level of children with rheumatoid arthritis befo | 1977 | Daily fluctuations in plasma cortisol levels were studied in three groups of children with rheumatoid arthritis. One group was untreated with hormones, the second treated with a depot preparation of tetracosactrin, and the third group with corticosteroid hormones. The results obtained were compared with the rhythm in normal children. The daily plasma cortisol fluctuations in children with rheumatoid arthritis who did not receive hormonal treatment differed from those of normal children by the presence of two distinct and characteristic cortisol levels: a peak between 8 a.m. and 12 noon and a minimal level between 4 p.m. and midnight (with a gradual rise after 4 p.m.). The curve of the daily cortisol rhythm in children with rheumatoid arthritis after tetracosactrin treatment was characteristic of the curve in normal children. Steroidtreated children with rheumatoid arthritis had virtually unchanged plasma cortisol concentrations throughout the day. | |
| 6607149 | Chronic arthritis in children. Juvenile rheumatoid arthritis. | 1984 Jan | Juvenile rheumatoid arthritis (JRA) is best defined as the condition of chronic synovitis in children. Such chronic childhood arthritis probably includes several distinct disease processes. Recognizable subgroups are systemic-onset disease (20%), rheumatoid factor-negative polyarthritis (25%), rheumatoid factor-positive polyarthritis (5%), pauciarthritis associated with antinuclear antibodies and chronic iridocyclitis (30%-35%), and pauciarthritis associated with sacroiliitis and HLA-B27 (10%-15%). Rheumatoid factor-positive polyarthritis appears to be the childhood equivalent of classic adult rheumatoid arthritis; the pauciarthritis associated with HLA B27 appears to be closely related to the spondyloarthropic diseases. Although there are no diagnostic laboratory tests, various subgroups differ in immunogenetic findings as well as in clinical appearance and prognosis. A wide variety of conditions (infectious diseases, childhood malignancies, genetic and congenital conditions, and noninflammatory musculoskeletal lesions) can mimic JRA and must be considered in the differential diagnosis. The outlook for most children with JRA is good; fewer than 20% have progressive destructive disease (generally those with rheumatoid factor-positive or systemic-onset disease). Therapy rests on the conservative use of antirheumatic drugs, active physical therapy programs, maintenance of activities, and attention to the psychosocial development of the whole child. Orthopedic surgery can be helpful, particularly in the rehabilitation of children who have suffered severe joint destruction or deformity. Combined orthodontic and oral surgery therapy can restore function and appearance for young people with the micrognathia of temporomandibular joint involvement. |
