She had morning stiffness lasting 60 minutes. The pt recommended starting methotrexate and considered the possibility of using etanercept which would be given SC twice weekly. The pt's mother felt that the naproxen had been entirely ineffective. The mother had purchased a number of over-the-counter herbal supplements and also had the pt sleeping on a magnetic bed but felt that the magnetic bed had not provided any relief. Impression: the pt most likely has an acute reactive arthritis. The physician found nothing to substantiate a diagnosis of polyarticular juvenile rheumatoid arthritis. The physician stated that the pt's arthritis may be related to Engerix-B. The physician recommended Relafen. A Rheumatology panel taken on 9/1/00 was within normal limits. On 9/22/00 the pt had a visit with the pediatric Rheumatology. The pt has been taking methotrexate and prednisone.
