Abstract
For the purposes of classification, it should be specified whether osteoarthritis (OA) of the knee is of unknown origin (idiopathic, primary) or is related to a known medical condition or event (secondary). Clinical criteria for the classification of idiopathic OA of the knee were developed through a multicenter study group. Comparison diagnoses included rheumatoid arthritis and other painful conditions of the knee, exclusive of referred or para-articular pain. Variables from the medical history, physical examination, laboratory tests, and radiographs were used to develop sets of criteria that serve different investigative purposes. In contrast to prior criteria, these proposed criteria utilize classification trees, or algorithms.

Induction of nerve growth factor expression and release by mechanical and inflammatory stimuli in chondrocytes: possible involvement in osteoarthritis pain

TL;DR: It is suggested that the overexpression of visfatin/NAMPT and IL-1β in the OA joint and the increased mechanical loading of cartilage may mediate OA pain via the stimulation of NGF expression and release by chondrocytes.

TL;DR: It is suggested that low-level laser therapy has no effect on pain in patients with knee OA, with the chosen laser type and dose regimen.

The 1982 revised criteria for the classification of systemic lupus erythematosus

TL;DR: The 1971 preliminary criteria for the classification of systemic lupus erythematosus (SLE) were revised and updated to incorporate new immunologic knowledge and improve disease classification and showed gains in sensitivity and specificity.

TL;DR: It was concluded that, to ensure maximum uniformity in grading x rays in field surveys and therapeutic trials, all readings should be made by the same observer, preferably at a single session.

Preliminary criteria for the classification of systemic sclerosis (scleroderma)

TL;DR: A multicenter, ongoing study of early-diagnosed cases of systemic sclerosis and comparison patients with systemic lupus erythematosus, polymyositis/dermatomyositis, and Raynaud's phenomenon was conducted in order to develop classification criteria for systemic sclerosis.

Preliminary criteria for the classification of systemic sclerosis (scleroderma). Subcommittee for scleroderma criteria of the American Rheumatism Association Diagnostic and Therapeutic Criteria Committee.

TL;DR: Proposed classification criteria for systemic sclerosis had a 97% sensitivity for definite systemic sclerosis and 98% specificity when applied to the case and comparison patients included in this study.
