To evaluate the quality of pain management in a teaching hospital rheumatology department. ⋯ Satisfaction with pain management (a subjective criterion) was good in our patients. However, no validated tools for measuring satisfaction are available, and measurements should be repeated to look for improvements over time. Limitations to these results include the placebo effect, the influence of memory, and the effects of the behavior of hospitalized patients. A repeat survey is needed.

To test the reliability and validity of a modified and translated version of the original Health Assessment Questionnaire (HAQ) on patients with rheumatoid arthritis (RA). ⋯ The Arabic HAQ is a reliable and valid instrument that can be self-administered to Arabic RA patients to evaluate their functional disability. Its measurement properties were comparable to versions in other languages.

Concepts related to the pathophysiology of reflex sympathetic dystrophy syndrome (RSDS) are changing. Although sympathetic influences are still viewed as the most likely mechanism underlying the development and/or perpetuation of RSDS, these influences are no longer ascribed to an increase in sympathetic tone. Rather, the most likely mechanism may be increased sensitivity to catecholamines due to sympathetic denervation with an increase in the number and/or sensitivity of peripheral axonal adrenoceptors. ⋯ They induce an inflammatory response (cutaneous erythema and edema) and lower the pain threshold. Neurogenic inflammation at the site of the lesion with neuromediator accumulation or depletion probably contributes to the pathophysiology of RSDS. However, no single neuromediator has been proved responsible, and other hypotheses continue to arouse interest.

To determine that opioid rotation can be useful for establishing a more advantageous analgesia/toxicity relationship in rheumatologic pain. ⋯ In rheumatologic non-malignant pain, the opioid rotation might allow the physician to bypass side effects or failure to alleviate pain in most cases.

Comparative Study
Validity of the French-language version of the Quebec back pain disability scale in low back pain patients in France.
The primary objectives were to evaluate the acceptability in France of the Quebec Back Pain Disability Scale (QBPDS) in its original French-language version and to study its correlational validity against indicators of impairment, pain, disability, psychological status, and perceived health status. ⋯ Our results confirm the good measurement properties of the original French-language version of the QBPDS in French hospital-clinic patients with chronic low back pain. Comparison of the QBPDS and DPQ in this study shows that the QBPDS is better for evaluating disability, whereas the DPQ evaluates the overall, functional, psychological, and social impact of low back pain.
