To assess the reliability, validity, and sensitivity to change of the Norwegian version of the childhood Health Assessment Questionnaire (CHAQ) and to examine the relationship between disability, disease severity, and psychosocial factors in patients with early juvenile rheumatoid arthritis (JRA). ⋯ The Norwegian version of the CHAQ is a reliable and valid instrument for measuring disability in children with early JRA. Pain, joint inflammation, and psychosocial factors are the most important correlates of disability and the CHAQ is sensitive to clinical change.

To test whether therapeutic diclofenac concentrations are attained in skeletal muscle tissue beneath the application site of an epicutaneously administered diclofenac foam formulation. ⋯ There is significant direct penetration of diclofenac into skeletal muscle following multiple epicutaneous administration. However, the concentration attained in individual subjects is not predictable and may be strongly influenced by individual skin properties.

Randomized Controlled Trial Clinical Trial
Diclofenac/misoprostol compared with diclofenac in the treatment of osteoarthritis of the knee or hip: a randomized, placebo controlled trial. Arthrotec Osteoarthritis Study Group.
Gastric (GU) and duodenal ulcers (DU) are common adverse effects of nonsteroidal anti-inflammatory drugs (NSAID). Endoscopically diagnosed upper gastrointestinal (GI) ulceration occurs in about 24% of longterm NSAID users. Coadministration of misoprostol with the NSAID reduces the incidence of NSAID induced GU and DU and their complications. However, compliance is limited by the different dosing regimens of misoprostol and NSAID and GI symptoms associated with misoprostol at its recommended q.i.d. dose. We compared the efficacy, safety, and incidence of endoscopic upper GI ulceration associated with the administration of 2 combinations of diclofenac (50 or 75 mg) and misoprostol 200 microg (D50/M200 t.i.d., D75/M200 b.i.d.), diclofenac 75 mg b.i.d., and placebo in a 6 week, randomized, double blind study in patients with osteoarthritis (OA) of the knee or hip. ⋯ Diclofenac 50 mg/misoprostol 200 microg t.i.d. and diclofenac 75 mg/misoprostol 200 microg b.i.d. are as efficacious as diclofenac 75 mg b.i.d. in the treatment of OA, but are associated with a significantly lower incidence of gastric and/or duodenal ulcers.

Comparative Study Clinical Trial
Longterm combination therapy of refractory and destructive rheumatoid arthritis with methotrexate (MTX) and intramuscular gold or other disease modifying antirheumatic drugs compared to MTX monotherapy.
To evaluate tolerability and efficacy of combination therapy with methotrexate (MTX)/parenteral gold or MTX/other disease modifying antirheumatic drug (DMARD, d-penicillamine or chloroquine) in comparison with MTX monotherapy in patients with longstanding destructive active rheumatoid arthritis (RA). ⋯ Combination therapy of MTX with parenteral gold or other DMARD is effective in reducing clinical and biochemical disease activity in patients with longstanding destructive RA with no greater risk of toxicity compared with MTX alone; our study however, did not show clear advantages of combination therapy versus monotherapy for effectiveness.
