Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
[Real time collection of pain profile in treatment with ibuprofen].
In an open three-center pilot study, 17 patients suffering from chronic persistent pain syndrome, due to osteoarthritis of the hip and knee or spondylarthrosis, were treated orally with 1800-2400 mg Ibuprofen per day for 3 weeks. The chronic pain syndrome and joint status were assessed by the physician at the beginning, and after 7, 14 and 21 days. Self-assessments were made by the patients six times daily during the full study period by means of battery-driven electronic diaries (E. ⋯ The closely-meshed real-time recording of pain course and other subjective data, such as adverse events or medication, etc., enables the physician to calculate more exactly and reliably improvement rates, as well as to carry out prognostic trend analyses and individual benefit-risk-ratio estimates. By comparing different kinds of data, each entered at the same time, plausibility checks are possible. The procedure presented here is considered to be a new valuable tool for reviewing subjective data from clinical drug trials.

Randomized Controlled Trial Comparative Study Clinical Trial[Evaluation of obstetrical pain by a questionnaire of adjectives. Comparison of 2 epidural analgesia protocols].
A French version of the McGill pain questionnaire, the "Questionnaire Douleur Saint Antoine" (QDSA), was assessed prospectively by comparing two epidural analgesia protocols using bupivacaine. One hundred women in labour who asked for epidural analgesia were randomly allocated to two groups and received either 0.25% or 0.5% bupivacaine (mean initial doses 32.5 and 50 mg respectively) with adrenaline 1 in 200,000. All the patients were then instructed to trigger a patient controlled analgesia (PCA) device for top-up doses of 0.25% bupivacaine with adrenaline 1 in 400,000 once they became aware of pain returning. ⋯ On the other hand, the affective part of the score was only correlated with the level of anxiety and behaviour. The sensory part of this score was the only one to show a difference between the different initial doses given to the patients. The results obtained with this series of patients underline the value of a multidimensional assessment of labour pain.

In this study carried out in a sample of 80 patients suffering from rheumatoid arthritis (RA) tried an attempt was made to answer the following questions: 1. are there pain factors with a wider range that are more generally applicable than those covered by current German questionnaires? 2. To what extent can somatic parameters predict pain factors? 3. To what extent can a patient's pain behavior (a patient's activity scores) predict pain factors? The study was based on data collected by means of the Pain Experience Questionnaire (PEQ), the McGill Pain Questionnaire MPQ, the West Haven-Yale Multidimensional Pain Inventory WHYMPI, the Measurement Of Patient Outcome Scale MOPO, as well as six different clinical parameters. ⋯ At a statistically significant level, the first factor can be predicted by the clinical variables. Regression of the activity scores on the factor "socio-emotional consequences" suggests a close correlation between the two variables, although the results failed to reach statistical significance. On the whole, the results strongly support the notion of integrating clinical, behavioral and cognitive findings in the diagnostic assessment of chronic rheumatoid pain patients.

19 patients between 23 and 65 yr. of age whose chronic back pain was caused by lumbosacral disk disease and 19 healthy volunteers matched for age and sex were studied. Pain thresholds under phasic and tonic heat stimulation and thermal thresholds for warmth and cold were measured on the right hand. ⋯ Hence, current back pain and experimental tonic pain seem to have an additive effect on pain perception because perceptual qualities are similar. Reduced somatosensory perception of chronic back pain patients could be demonstrated for temperature sensitivity and to a lesser degree for phasic pain, but as a consequence of the "opposing" effect of current back pain, not for tonic pain perception.
