BACKGROUND: In clinical practice, we noticed a greater than expected spread of sensory spinal block in patients with rheumatoid arthritis. We decided to test this impression and compared the spread of standard spinal anaesthesia in rheumatoid and non-rheumatoid control patients. METHODS: Spinal anaesthesia with 3.4 ml (17 mg) of plain bupivacaine was administered to 50 patients with seropositive rheumatioid arthritis and to 50 non-rheumatoid control patients. The protocol was standardised for all patients...

Analysis of 878 hand films shows the carpo : metacarpal ratio to be a sensitive quantitative index of progression of carpal involvement in rheumatoid arthritis. This index, easily calculated by dividing the lengths of the carpus by the third metacarpal, showed marked consistency in the ratio regardless of age, race, or sex in normal adults. A decreased ratio correlated highly with recognized radiographic stages of rheumatoid arthritis and thus suggested utility in longitudinal studies of patients with this disease...

The agglutination of Ig-coated particles by human RF or Clq can be inhibited by Ig aggregates or AgAb complexes. The effect of Ig class was studied by means of agarose-linked human monoclonal Igs. RF was inhibited by all subclasses of IgG and IgA but not by IgM, whereas Clq reacted with IgM, IgG3 and IgG1. Heat-aggregated IgG3 was fractionated by gel-filtration on Ultrogel. Inhibition was restricted to certain fractions of aggregates, viz (IgG3) approximately 7 and (IgG3) approximately 21 for RF, and (IgG3) approximately 10, (IgG3) approximately 14 and (IgG3) approximately 27 for Clq...
