A 5-yr follow-up of an arthritis education programme is reported. After adjustment for those lost, deceased or moved away, the 5-yr response rate was 75% among intervention subjects and 78% among controls. Individuals who participated in the education programme maintained their increased knowledge in some aspects. The relative difference in pain and disability over 5 yr was greater in the control group. Most individuals were less active at practising exercise after 5 yr. Improvement in performing exercise and joint protection shown at 12-months follow-up did not persist. Additional questions after 5 yr showed that participants in the education programme had significantly more contact with rheumatologists, physiotherapists and occupational therapists. The participants developed an increased internal sense of control of the disease between 12 months and 5 yr. There was also a significant reduction in reported problems with their disease after 12 months, maintained after 5 yr. This may indicate that patient education contributes to the patient's feeling of responsibility for, and ability to cope with, their diseases.

1 The disposition of total and free prednisolone has been studied in four male and four female volunteers, each of whom received an intravenous dose of 0.075 mg/kg (low) and 1.5 mg/kg (high) of prednisolone at both 06.00 h and 18.00 h. 2 For the low dose, free prednisolone clearance was 14% lower (P = 0.012) and time-averaged prednisolone free fraction was 22% higher (P < 0.001) in the morning, there being no circadian difference in total prednisolone clearance. There was no circadian differences in prednisolone disposition at the high dose. These findings are consistent with a mechanism in which cortisol causes a simultaneous competitive inhibition of prednisolone clearance and plasma protein binding at low, but not at high prednisolone doses. 3 Prednisolone clearance was higher in female than in male subjects, the mean increase being 18% (P = 0.022) for total prednisolone and 21% (P = 0.036) for free prednisolone. 4 Mean total prednisolone clearance and steady-state distribution volume were two-fold higher at the high vs the low dose (P < 0.001), but free prednisolone clearance showed a dose dependent decrease of 11% (P = 0.019). There was no change in free prednisolone steady-state distribution volume.

Forty-five patients with acromegaly or gigantism were reviewed for musculoskeletal abnormalities. Abnormalities of peripheral joints occurred in 74% of the patients and spinal involvement in 47%, leading to significant morbidity. Joint abnormalities most frequently affected the large joints (hips, knees and shoulders) but the wrist and hand were also involved. The radiological features of acromegalic arthropathy are described, including vertical widening of the hip joint, enthesopathy and osteophytosis. A favourable response to treatment is associated with a less severe arthropathy and a good functional outcome.

1. Enteric coated sodium salicylate 4.8 g daily was compared with the same dose of enteric coated aspirin in 18 patients with rheumatoid arthritis. 2. After an initial washout period lasting 3 days, patients were randomly allocated to treatment with sodium salicylate or aspirin. After 2 weeks the two treatments were crossed over. 3. Pain relief, reduction in articular index of joint tenderness, increase in grip strength, decrease in digital joint circumference and patients' assessment showed significant improvement with both treatments compared with the washout period. No significant differences were found between the two therapies. 4. No correlation was found in the degree of improvement in any of the clinical outcomes and the salicylate concentrations at steady state.
