RESUMO
Reflex sympathetic dystrophy (RSDS) is a syndrome of hyperesthesia and vasomotor disturbance of an extremity, often following trauma or an inflammatory process. We describe a patient with systemic lupus erythematosus (SLE) and recurrent RSDS involving all 4 extremities at various times during her illness. Treatments, including corticosteroid use, physical therapy and at times sympathetic nerve blockade led to the resolution of each episode. We suggest the diagnosis of RSDS be considered in patients with connective tissue diseases who present with atypical pain syndromes not attributable to their primary illness.

Twenty-nine children with juvenile rheumatoid arthritis were studied to determine the safety and efficacy of methotrexate therapy. The initial dose of methotrexate averaged 7.1 mg/m2/wk and was given as a single, oral weekly dose or as three divided doses, each separated by 12 hours. Current antiinflammatory medications were continued; 25 of 29 children had had lack of efficacy, and 8 of 29 had toxic effects, with one or more prior drugs such as intramuscularly or orally administered gold, hydroxychloroquine, or D-penicillamine. Intolerable corticosteroid dependency or toxic effects were present in 18 of 29 cases. Methotrexate-treated patients were examined monthly; minimum treatment duration required to assess efficacy and toxicity was 6 months. The range of treatment duration was 8 to 39 months (mean 18.5 months). Efficacy was assessed by comparing pretreatment versus posttreatment fever and rash, swollen-joint counts, articular indexes, duration of morning stiffness, functional class, hemoglobin levels, and platelet counts. Treatment with methotrexate effectively controlled fever and rash in 83% of children with systemic juvenile rheumatoid arthritis, reduced morning stiffness by 63%, eliminated recalcitrant joint restriction in 48%, and reduced numbers of swollen joints and swelling indexes by 46% and 52%, respectively. No significant toxic effects were observed. Juvenile rheumatoid arthritis of long duration, or with major erosions, was more likely to be refractory to methotrexate therapy. We recommend earlier consideration of methotrexate in place of other slow-acting antirheumatic drugs for juvenile rheumatoid arthritis not responding well to usual therapy. Future studies should address potential methotrexate toxic effects in the lungs and reproductive system, as well as outcome after discontinuation of methotrexate treatment.

We report 25 children with oligoarticular arthritis associated with Lyme disease. There were 16 boys (male/female ratio 1.8:1); ages ranged from 2 to 15 years. Thirteen (52%) children had no history of erythema chronicum migrans or other rash. Thirteen had temperatures as high as 41 degrees C for up to 2 months before the onset of arthritis. Twelve recalled definite tick bites. Ten (40%) children, of whom seven had no history of rash, were hospitalized for presumed septic arthritis. Another four had diagnoses of pauciarticular juvenile rheumatoid arthritis for as long as 3 years. Seven patients had less acute, recurrent episodes of synovitis. Two children had seventh nerve palsies 2 months before onset of arthritis. All patients had antibodies to the Lyme spirochete. In 14 patients, synovial fluid white blood cell counts ranged from 180 to 97,700/mm3 (greater than or equal to 76% polymorphonuclear leukocytes). Antibiotic therapy was effective in all patients; in 13, orally administered therapy alone resulted in elimination of synovitis and recurrent attacks. Lyme arthritis may be confused with acute bacterial septic arthritis or recurrent "pauciarticular juvenile rheumatoid arthritis," particularly when there is no history of erythema chronicum migrans.
