Randomized Controlled Trial Multicenter Study
The Reciprocal Effects of Pain Intensity and Activity Limitations: Implications for Outcomes Assessment in Clinical Trials.
To examine the reciprocal effects of pain intensity and limitations in physical functioning over time. ⋯ These analyses showed that a decrease in activity limitations results in a decrease in pain intensity. However, changes in pain intensity had no effect on subsequent activity limitations in the study sample. None of the 3 outcome variables emerged as being more responsive to treatment than the others.

Multicenter Study
Factors Associated With Outcome after Superior Hypogastric Plexus Neurolysis in Cancer Patients.
Superior hypogastric plexus neurolysis (SHP-N) has been shown in uncontrolled studies to provide intermediate-term benefit in a majority of patients with pain secondary to genitourinary, gynecologic, and colorectal cancers. The purpose of this is to determine factors associated with treatment outcome. ⋯ Selecting patients based on demographic and clinical variables may improve treatment outcomes for SHP-N. Larger, prospective studies are needed to confirm our results and better refine selection criteria better.
