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.

Randomized Controlled Trial Comparative Study Clinical Trial
[Validation of electronic by conventional pain diaries].
A new type of electronic pain diary was validated in an open, randomized, crossover study. The main target variables were the comparison of the correctly realized pain assessment entries as well as the recording of the number of adverse events. Selected for the study were 20 patients, who were either hospitalized, partially-hospitalized or treated on an out-patient basis, with painful spondylogenic spinal syndrome or osteoarthritis of the trunk-proximal large joints. ⋯ Likewise, the functional impairment of the affected joints as well as the swelling decreased markedly. The advantages of the electronic data recording system, i.e. closely-meshed controls can be carried out, transcriptional errors are minimized, data can be processed on-line, no possibility to subsequently change an entry, stand in contrast to the feature that there is no possibility to make free-style entries. The employment of the electronic system in the recording of individual data and subjective data represents a substantial improvement with regard to the quantity and quality of the data.

Randomized Controlled Trial Comparative Study Clinical Trial
[Initial results of the reliability and validity of a German-language scale for the quantitative measurement of postoperative pain in young children].
In a previous study it was proved impossible to evaluate the validity of a system modified according to McGrath et al. for measuring postoperative pain in children. Three reasons were postulated for this result. The analgesics used did not modulate the pain in such a manner that the statistical analysis was effective; or the postoperative pain had an acute onset or fluctuated and the regular observations did not allow detection of the pain peaks; or the system used did not measure pain. ⋯ RESULTS. A replication verified the results of the previous study: the factor analysis resulted in a one-factorial solution. Of the 8 items (wakefulness, wake-up reactions, crying, position of the trunk, position of the legs, verbal communications on being asked about pain, special defense against stimuli) only 4 had a sufficiently substantial load on all measurements (crying, facial expression, position of the trunk and position of the legs).

Randomized Controlled Trial Comparative Study Clinical Trial
Lack of effect of clonidine and pentoxifylline in short-term therapy of diabetic peripheral neuropathy.
The goal of this study was to confirm or rule out anecdotal reports of beneficial effects of clonidine and pentoxifylline in the treatment of painful diabetic peripheral neuropathy. Clonidine was administered to 16 subjects at two dosage levels (0.1 and 0.2 mg/day) and was compared to placebo in a crossover design, with each phase lasting 4 wk. ⋯ There was a significant decrease in pain score from baseline with both active drugs (P less than 0.05), but this was no better than the response to placebo (P less than 0.30 for clonidine and P less than 0.95 for pentoxifylline). This study does not demonstrate a short-term benefit of either clonidine or pentoxifylline in the treatment of peripheral neuropathy.

Randomized Controlled Trial Comparative Study Clinical Trial
[Critical aspects of an outside evaluation of postoperative pain in infants. A placebo-controlled double-blind study of the question of the reliability and validity of the measurement system].
Postoperative analgesia in infants and young children is a topic of growing interest in pediatric anesthesia. Two systems measuring postoperative pain in this group of patients have been offered recently: CHEOPS (Childrens Hospital of Eastern Ontario Pain Scale) by McGrath et al. and OPS (Objective Pain Scale) by Hannallah et al. and Broadman et al. [3, 7, 8]. Both systems are economical and not reactive, but their validity is not satisfying. ⋯ The design of the study was accepted by the ethic committee with the provision that neither a sedative nor an analgesic drug should be withheld from any child if indicated. Therefore, all children who seemed to feel discomfort according to the subjective impression of the anesthetist received midazolam intraveneously to a maximal dose of 2 mg. All the behavioral data were included in a factor analysis (principal components)...
