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).

One aim of this study was to evaluate the relation of scores on the Multidimensional Affect and Pain Survey (MAPS) that was administered before surgery to postoperative morphine consumption and patient-controlled analgesia. A second aim of the study was to compare the ability of MAPS administered postsurgery with the commonly used Numerical Pain Rating Scale to predict patient-controlled analgesia behavior. ⋯ The emotional states and attitudes of the patients toward pain before surgery are important factors in determining patient-controlled analgesia pressing behavior and postoperative demand for analgesics.

Randomized Controlled Trial Clinical Trial
Agency orientation and chronic musculoskeletal pain: effects of a group learning program based on the personal construct theory.
This study evaluated the effects of a group learning program on patients with chronic musculoskeletal pain and high absenteeism and investigates what characterizes those patients who may benefit from such a program. The learning program was based on personal construct theory. The theory included the following: (1) participation in an educational program is related to a favorable outcome across the outcome measures (pain, pain coping, management of daily life, absenteeism, and use of health care), (2) patients with high agency orientation (i.e., inner-directed) cope with their pain and manage daily life in a better manner than do patients with low agency orientation (i.e., outer-directed), and (3) patients with high personal control, measured in terms of agency orientation, in terms of health locus of control, or in both terms, will benefit more from the educational program than will patients with low personal control. ⋯ The intervention group reported a significantly higher score for the variable "management of everyday life" (p <0.005) and for the variable "health care consumption" (p <0.001) than did the control group. Patients with high agency orientation benefited more from the program with regard to pain reduction and improved pain coping than did those patients with low agency orientation (p <0.05). Patients with high agency orientation also reported less absenteeism than did those patients with low agency orientation (p <0.05).
