The authors report three cases of migratory algodystrophy of the knee. Repeated isotope bone scan, CT scan and nuclear magnetic resonance were used to monitor the movement in situ of the pathophysiological process of algodystrophy. In one case, CT scan revealed localised hypertrophy of the soft tissues located immediately over the bone lesions.
Five-hundred-thirteen regional intravenous guanethidine blocks were carried out in 125 cases of algodystrophy (118 adults), after failure of other treatments in 120 cases (Group I) and without previous treatments in 5 (Group II). A positive result occurred in 85 cases of Group I (71%) and in the 5 cases of Group II, after 4.5 +/- 1.7 blocks. In Group I the results did not differ significantly between upper (33 cases) and lower (87 cases) limb or in regard to sex, age, duration of disease, nature of previous treatments. The presence of psychic disorders was accompanied by less frequent (p less than 0.02) positive results. The tolerance was satisfactory in 85.6% of cases: 22 moderate side effects authorized a continuation of the blocks, 22 serious ones indicated interruption, especially one case of thrombophlebitis and another one of very transitory acute ischaemia. The risk of intolerance was significantly raised (p less than 0.02) by age. The regional guanethidine blocks seemed to be a good treatment for algodystrophy after failure of other treatments.

In a preliminary retrospective study, 418 regional sympathetic blocks with guanethidine administered as treatment of 103 cases of algodystrophy gave 70 p. cent of positive results versus 55 p. cent in case of psychic disorders. The tolerance was correct in 85 p. cent but was decreased by old age.
Two sets of criteria have been proposed to discriminate spondylarthropathies (SA) from other rheumatic diseases. To evaluate their performance, we conducted a cross-sectional study in the patients observed during one week in 28 French Departments of Rheumatology by 91 staff-teaching physicians. The physicians had to apply these criteria to all their patients and had to classify them as definite SA, definite other rheumatic disease or possible SA. The analysis performed on the 2,088 patients with a definite diagnosis (124 SA and 1,964 controls) showed the following results: (table; see text) Of the 140 patients with possible SA, 37 fulfilled both sets of criteria, 22 the ESSG criteria alone and 12 the Amor criteria alone. These data suggest that a) the overall performance of these two sets of criteria is similar; b) this performance is better in the group of patients with a definite diagnosis; c) the patients without a definite diagnosis require a longer follow-up to assess the clinical relevance of these two sets of criteria.

This retrospective review presents the results of treating 199 patients with sympathetic reflex dystrophy of the foot: 141 of traumatic and 58 of non-traumatic origin. Calcitonin (177 patients) improved or cured 62.2 p. 100 of these patients and was equally effective for pseudo inflammatory and ischemic (cold) stages of the disease. Among the therapeutic means available, regional sympathetic blockade with guanethidine (49 patients, 163 treatments) provided 80 p. 100 improvement or cure, with twice as many patients in the hot phase as in the cold. All patients were cured: 75 p. 100 in less than a year, 4.6 p. 100 with moderate, non-handicapping sequelae. Normal activities were partially reinstituted 3.5 +/- 2.8 months (post-trauma) or 1.9 +/- 1 months (non-trauma) after treatment. They were completely possible 5 months after the end of treatment in both groups. In the trauma group, 73 patients had work-related accidents: their evolution was the same as that of the other patients in this group. When present, psychological background (35 p. 100 of the cases) only delayed progress in the non-traumatic group (9.9 vs 6.5 months).

Shoulder bursitis seldom appears in rheumatoid arthritis. It is usually associated with an involvement of the omohumeral joint but it may be isolate and sometimes indicative. The production of foreign bodies is very rare (3 published cases). We report about one observation of subacromiodeltoid bursitis with rice bodies, associated with rheumatoid arthritis following a severe evolution.
