Randomized Controlled Trial
Sensitivity to change and internal consistency of the Northwick Park Neck Pain Questionnaire and derivation of a minimal clinically important difference.
To estimate the sensitivity to change and internal consistency of the Northwick Park Neck Pain Questionnaire (NPQ) and derive its minimal clinically important difference (MCID). ⋯ These results show high internal consistency and sensitivity to change for the NPQ, and provide an MCID that allows participants with varying levels of severity to demonstrate improvement.

Clinical Trial
Determinants of patient-controlled epidural analgesia requirements: a prospective analysis of 1753 patients.
Patient-controlled epidural analgesia (PCEA) has been widely used in postoperative pain management. Many factors may correlate with PCEA requirements but no previous study has ever investigated this subject. Therefore, we conducted this study to explore the relationship among patients' characteristics and total PCEA consumption during the 3-day postoperative course. ⋯ Our study demonstrated the association between patients' characteristics and total PCEA requirements from a large-scaled clinical data. Surgical procedures have more influence on PCEA consumption than demographic variables. Background infusion rate of PCEA could be determined from our predictive model.

Multicenter Study Clinical Trial
The validity and reliability of the graphic rating scale and verbal rating scale for measuring pain across cultures: a study in Egyptian and Dutch women with rheumatoid arthritis.
To compare the validity and reliability of a graphic rating scale (GRS) and a verbal rating scale (VRS) for measuring pain intensity in young female Egyptian and Dutch patients with rheumatoid arthritis (RA). ⋯ The study confirmed that the GRS and VRS were reliable and valid in the total study cohort. Within the individual countries, the GRS seemed to perform better than the VRS.

Randomized Controlled Trial
Preoperative cotreatment with dextromethorphan and ketorolac provides an enhancement of pain relief after laparoscopic-assisted vaginal hysterectomy.
Both N-methyl-D-aspartate receptor antagonists and nonsteroidal anti-inflammatory drugs have been demonstrated to produce better postoperative pain relief. The concept of multimodal analgesia has also been used for clinical pain management. The aim of the present study was to examine the analgesic effect of preoperative cotreatment with dextromethorphan (DM) and ketorolac on postoperative pain management after laparoscopic-assisted vaginal hysterectomy (LAVH). ⋯ Preoperative treatment with both DM and ketorolac diminish postoperative pain. Our results suggest that the N-methyl-D-aspartate antagonist-DM and the nonsteroidal anti-inflammatory drugs-ketorolac cotreatment provide an enhancement of analgesia for postoperative pain management in patients after LAVH surgery.

Extramedical prescription pain reliever use has generated much public concern; however, little is known regarding its epidemiology in the general population. ⋯ This study supplies data that can improve our understanding of factors associated with the extramedical use of prescription pain relievers among 2 distinct stages of use.
