Clinical and laboratory manifestations, disease course, outcome, and HLA associations were studied in an inception cohort of 62 subjects with adult Still's disease (ASD) from 5 Canadian universities. Twenty-eight patients (45%) were female and the median age at disease onset was 24 years. In general, the clinical features observed in our patients were(More)
Ten posterior subtalar joints of 8 patients with rheumatoid arthritis and 12 posterior subtalar joints of 6 cadavers were studied by contrast synoviography. In the rheumatoid group the abnormalities included posterior capsule distension, filling defects caused by hypertrophic synovitis, limited or irregular filling of the anterior recess of the joint in 5(More)
We describe a young male patient who presented with acute podagra after jogging activity. He had no underlying pathology. Polarized light microscopy of the synovial fluid from his first metatarsophalangeal joint revealed numerous negative birefringent spherulites about 6 microns in diameter, presenting the typical appearance of Maltese crosses. The molar(More)
Nuclear receptor retinoid-related orphan receptor alpha (RORα1) is a member of ROR-family receptors. It is broadly expressed in various tissues and organs during embryonic development. However, so far, little is known about its function in bone. Here, we have elucidated the expression and function of RORα1 in human MG-63 osteoblast-like cells. Reverse(More)
A 17-year-old Cambodian-born female was recently evaluated for subacute seronegative arthritis involving both ankles and the right midfoot. Suboptimal response to a nonsteroidal anti-inflammatory drug prompted open synovial biopsy, which showed intensive eosinophilic infiltration of the synovial structures. Slight peripheral eosinophilia had been found(More)
OBJECTIVE To assess risk factors for adult Still's disease (ASD). METHODS A matched case-control study of 60 patients with ASD and 60 same sex siblings closest in age was conducted. Subjects were recruited from cohorts in Eastern Canada, Pittsburgh, and the Arthritis, Rheumatism, and Aging, Medical Information Systems (ARAMIS). A questionnaire was used to(More)
One hundred and twelve patients with classical or definite rheumatoid arthritis (RA) were randomly assigned to receive either sodium aurothiomalate (GSTM) or auranofin (AF). Monthly clinical assessments (morning stiffness, grip strength, articular index, pain, quality of life) and concurrent hematological, biochemical, and urine studies were performed to(More)
Two patients with rheumatoid arthritis and one with Sjögren syndrome had a severe sensorimotor neuropathy preceding or up to 5 years after the onset of the disease. Electrophysiologic and sural nerve biopsy studies revealed an axonal neuropathy. Myelinated fibers were affected to a greater extent than unmyelinated axons. Peripheral nerve damage was related(More)
We compared the effectiveness of Auranofin, and sodium aurothiomalate (SATM) given for 2 years to patients with rheumatoid arthritis. This was an open trial with randomized entry to 2 treatment groups of 60 patients each. Only 40% of patients completed 2 years of treatment but these showed significant improvement in their indices of disease activity.(More)
The Arthritis Impact Measurement Scales (AIMS) questionnaire was administered to 57 patients with adult Still's disease (ASD) and 104 controls. Six of the 9 scales were consistent for both groups (Cronbach's alpha greater than or equal to 0.70). Two scales, Mobility and Dexterity, were consistent for ASD only (alpha greater than or equal to 0.70). The(More)
