Twenty-seven clinical trials that evaluated the efficacy of acupuncture in the treat ment of primary headaches (migraine headache, tension-type headache, and mixed forms) were reviewed. In the majority of the trials (23 of the 27 trials), it was concluded that acupuncture offers benefits in the treatment of headaches. ⋯ Acupuncture methods need individualization, a carefully selected placebo ("minimal acupuncture" seems to be best), and the crossover design must have adequate time between the two treatment periods. Clinical trials that evaluate acupuncture frequently are characterized by several inadequacies (including some from these evaluating headaches), but it seems that additional clinical research is necessary to confirm its efficacy and to clarify its indications.

Comparative Study Clinical Trial
Comparison of epidural butamben to celiac plexus neurolytic block for the treatment of the pain of pancreatic cancer.
To compare pain relief in metastatic pancreatic cancer patients between neurolytic celiac plexus block (NCPB) and epidural 5% butamben suspension (EBS), a material-based delivery system of a local anesthetic that produces a long-lasting differential nerve block. ⋯ EBS appears to be a safe and effective alternative to NCPB in the treatment of pancreatic cancer pain.

There is a need to identify pretreatment patient indicators, which are predictive of the successful enrollment and completion of chronic pain treatment programs. Recent evidence suggests the Pain Stages of Change Questionnaire can predict enrollment and completion of a 10-session cognitive-behavioral pain management program. The purpose of this study is to determine whether the pretreatment Stages of Change Questionnaire can predict patients who would complete a cognitive-behavioral pain treatment program. ⋯ The Stages of Change Questionnaire is a potentially useful tool; however, the current scoring method is insufficient to recommend its use as an inclusion or exclusion criterion for enrollment in a cognitive-behavioral program.

Patients with complex regional pain syndrome type I (CRPSD1) may have thermal allodynia after application of a non-noxious thermal stimulus to the affected limb. We measured the warm, cold, heat-evoked pain threshold and the cold-evoked pain threshold in the affected area of 16 control patients and patients with complex regional pain syndrome type 1/RSD to test the hypothesis that allodynia results from an abnormality in sensory physiology. ⋯ This study suggests that thermal allodynia in patients with CRPS1/RSD results from decreased cold-evoked and heat-evoked pain thresholds. The thermal pain thresholds are reset (decreased) so that non-noxious thermal stimuli are perceived to be pain (allodynia).
