CONCLUSION: IL-17 family members are varyingly expressed in rheumatoid nodules. The paucity of IL-17A in nodules suggests an important difference from that observed in the synovium. The expression of IL-23 below a critical threshold level seems the most likely explanation for the virtual absence of IL-17A. The presence of tissue...

Some confusion exists between these two subjects and several papers are not indexed correctly. This search covers both subjects

The presence of rheumatoid nodules is the major extra-articular feature of rheumatoid disease, occurring typically within the subcutaneous tissues in relation to the extensor surfaces of the wrist and elbow. Rheumatoid nodule formation within the central nervous system is rare.' We report a case of a lumbar extradural rheumatoid nodule giving rise to spinal nerve root compression.

We studied the histology of the cement-bone interface and the regenerated synovium in ten aseptically loosened arthroplasties in rheumatoid patients. In two patients we found rheumatoid nodules at the cement-bone interface and marked lymphoplasmacytic infiltration in another three. Failed joints in osteoarthritic patients did not show these changes, and it...
