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
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.

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.

To examine the factor structure of the Beck Depression Inventory version II (BDI-II) in patients seeking treatment for chronic pain, using exploratory and confirmatory factor analysis and provide comparative data for use with similar patient populations. In addition, to consider the utility of using BDI-II subscale scores to further inform the management of patients with chronic pain. ⋯ Results are consistent with studies using previous versions of the BDI in suggesting that 2-factor scores may be more clinically useful in the assessment of patients referred with chronic pain.

To describe a patient with spontaneous intracranial hypotension (SIH) secondary to multiple sites of cerebrospinal fluid (CSF) leaks, a rarely described phenomenon. To compare computerized tomography-myelography with radionuclide cisternography as confirmatory diagnostic aids in SIH. ⋯ In a patient with SIH, a computerized tomography-myelography should be performed if an initial epidural blood patch is ineffective. This is to show the vertebral level and site(s) of CSF leak and to guide the physician to the ideal vertebral level for the epidural blood patch.
