To test the hypothesis that rheumatoid arthritis in patients in China is milder in severity than that in patients in a western country, a comparison was made of 2 series of consecutive outpatients with definite or classic rheumatoid arthritis who were attending referral centers in Melbourne, Australia and Shanghai, China. This paper reports the findings on radiographs of the wrists and hands. Making allowances for age and duration of disease, changes were more frequent and severe in the Australian patient series, particularly at the metacarpophalangeal joints.

A comparison was made of two series of consecutive outpatients with a presumptive diagnosis of rheumatoid arthritis (RA) attending referral centres in Melbourne and Shanghai. No significant differences were observed in disease onset, course, presence of antinuclear antibodies (ANA), or seropositivity. In the Australian series there was a higher frequency of nodules, Raynaud's phenomenon, carpal tunnel syndrome, and 'classical' in comparison with 'definite' disease, and a lower frequency of lymphadenopathy and hepatomegaly. Joint tenderness and soft tissue swelling tended to be more marked in the Chinese series, while deformity and limited range of movement were less severe. Drug therapy was similar overall but influenced by drug availability. Peptic ulceration was recorded in 28% of the Australian series but in only 6% of the Chinese; although 25% of the Chinese were receiving antacids and 6% antiulcerants. X-rays of hands and feet showed more severe disease in the Australian series. The older age group and longer duration of the disease in the Australian patients, who had more chronic and less active disease, may have influenced some of these results.
The most junior resident medical officer soon becomes proficient at lumbar puncture and pleural aspiration but placement of a needle in a synovial cavity is approached with less confidence. Although only a part of the management of soft tissue rheumatic conditions, a carefully given corticosteroid injection can be dramatically effective for severe pain localised to a bursa, tendon sheath or synovial space.
IgG-containing antigen-antibody complexes were detected in the sera of all of 7 patients with the systemic form of juvenile chronic arthritis, usually at high levels. Only 9 of 25 patients with the polyarticular form had such complexes, usually at low levels. Three patients had low levels of serum IgA which were probably drug induced; the one patient with low C2 and the 3 with low yeast opsonisation were probably not more than to be expected in a random population.
Naproxen at 10 mg per kg body weight was compared with aspirin at 80 mg per kg body weight in children suffering from juvenile chronic polyarthritis. It was found to be as effective as aspirin, with certainly no more and possibly fewer gastrointestinal side effects. A long-term tolerance study up to 12 months confirmed that naproxed was a satisfactory nonsteroidal anti-inflammatory drug in the management of various types of juvenile chronic arthritis.

Juvenile ankylosing spondylitis, as a clinical entity, is outlined. A double-blind trial compared Safapryn and Butazolidin, each given for 3 months, for 15 treatment periods in 11 patients. No differences were shown, but the study highlighted the problems of assessing this condition, and some comments are made, hopefully, to guide further investigators in this field.
