Predictors of stenosing tenosynovitis in the hand and hand-related activity limitations in patients with rheumatoid arthritis.

Objectives: To identify early predictors of stenosing tenosynovitis in the hand and hand-related activity limitations in patients with rheumatoid arthritis (RA).

Design: A longitudinal study of an inception cohort.

Setting: A large outpatient clinic.

Prevalence of hand symptoms, impairments and activity limitations in rheumatoid arthritis in relation to disease duration.

Objective: To determine the prevalence of hand and wrist symptoms and impairments, and the resulting activity limitations in relation to disease duration in patients with rheumatoid arthritis.

Design And Patients: A cross-sectional study included 200 consecutive patients with rheumatoid arthritis in 4 categories of disease duration: 2-4, 4-6, 6-8 and ≥ 8 years. Patients were asked about the presence of various hand and wrist symptoms, and underwent a standardized physical examination.

Trabeculated right ventricular free wall in the chicken heart forms by ventricularization of the myocardium initially forming the outflow tract.

Recent molecular lineage analyses in mouse have demonstrated that the right ventricle is recruited from anterior mesoderm in later stages of cardiac development. This is in contrast to current views of development in the chicken heart, which suggest that the initial heart tube contains a subset of right ventricular precursors. We investigated the fate of the outflow tract myocardium using immunofluorescent staining of the myocardium, and lineage tracer, as well as cell death experiments.
