OBJECTIVE To determine the population incidence of juvenile rheumatoid arthritis (JRA) in Quebec. METHODS We obtained data from Quebec's physician claims database. Incident cases were defined as having a visit for JRA in 2000, no visit in the previous 3 years, a confirmed diagnosis by an arthritis specialist, or having >/= 2 visits to any physician for JRA, >/= 2 months apart but within 2 yea...

Two questionnaires were developed for measuring disability due to juvenile rheumatoid arthritis (JRA), one based on patient reports and one on parent reports. These questionnaires were termed the Juvenile Arthritis Functional Assessment Report for Children (JAFAR-C) and for Parents (JAFAR-P). The questionnaires were administered to 72 JRA patients ages 7-18 years and to their parents. Responden...

In recent years, there have been many new developments in the field of regulatory T cells (Treg), challenging the consensus on their behaviour, classification and role(s) in disease. The role Treg might play in autoimmune disease appears to be more complex than previously thought. Here, we discuss the current knowledge of regulatory T cells through animal and human research and illustrate the r...

OBJECTIVE To determine the degree to which mothers of children with juvenile rheumatoid arthritis (JRA) show an overprotective or highly controlling interaction style. METHOD We videotaped 84 mother-child pairs (42 JRA and 42 healthy, ages 6 to 13) while working on a collaborative problem-solving task. Based on physical therapy evaluations, children in the JRA group were assigned to "more sev...

Parents of 135 children with juvenile rheumatoid arthritis (JRA) completed a mailed questionnaire about problems at school. Writing was the most frequently reported difficulty, with hand involvement causing more problems than decreased mobility. Compared to children with pauciarticular JRA, those with polyarticular or systemic JRA were significantly more likely to miss school, experience proble...

Rheumatoid rosette in juvenile rheumatoid arthritis. The rheumatoid rosette test was performed in 159 children.

Background: Rheumatoid arthritis (RA) and juvenile rheumatoid arthritis (JRA) are systemic autoimmune diseases characterized by synovitis and a wide range of extra articular manifestations. Ocular involvement occurs frequently in both diseases and it may affect all layers. Objectives: To identify different types of ocular involvement in cases of Adult Rheumatoid Arthritis (RA) and Juvenile Rheu...

One hundred fifty two patients with Juve­ nile rheumatoid arthritis were retrospectively studied in an effort to determine the efficacy of synovectomy in thi's disease.  Twenty-five of 117 closely observed patients underwent synovectomy following failure to be controlled by more conservative measures. Analysis of the end-results on the basis of age, sex, stage of disease, and individual joints...

The presentation of juvenile psoriatic arthritis (JPsA) has long been recognized to be clinically heterogeneous. As the definition of JPsA expanded to accommodate atypical manifestations of psoriasis in young children, studies began to reflect an increasingly clear biphasic distribution of age of onset, with peaks in the first few years of life and again in early adolescence. These two subpopul...
