Multicenter Study Clinical Trial
A multi-center analysis evaluating factors associated with spinal cord stimulation outcome in chronic pain patients.
In addition to its conventional use as a treatment for refractory neuropathic extremity pain, spinal cord stimulation (SCS) has recently emerged as a possible treatment for visceral and arthritic pain. But concurrent with the expansion of possible conditions amenable to SCS, other studies have questioned the long-term efficacy of SCS for traditional indications. These disparate findings argue strongly for the refinement of selection criteria. The purpose of this study is to identify correlates of outcome for SCS. ⋯ Although weak associations with outcome were noted for several clinical variables, none was strongly associated with trial and permanent implantation results. The strongest predictor of a negative SCS outcome was obtaining <50% pain relief during the trial period.

Age and gender may exert important influences on opioid responsiveness and chronic pain. These effects have not been explored in the setting of chronic intrathecal (IT) opioid therapy. The objective of this study was to evaluate the effect of age and sex on IT opioid requirements during the first year after implantation of an intrathecal drug delivery system (IDDS) in chronic noncancer pain patients. ⋯ IT opioid dose escalation occurs more steeply in the younger (under 50 years old) IDDS patient population without a concomitant significant decrease in oral consumption of opioids. Age-dependent changes may have important clinical implications on the effectiveness of IT opioid therapy in noncancer pain and its potential complications.

ReviewUse of acupuncture as a treatment method for chronic prostatitis/chronic pelvic pain syndromes.
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is the most common category of clinical prostatitis. The etiologic factors of CP/CPPS still remain unknown, and standard therapies often fail to achieve sustainable amelioration of symptoms; therefore, various treatment therapies have been approached. ⋯ In this article, we review the recent clinical research using acupuncture to reveal its clinical utility for CP/CPPS and the possible mechanisms of action. This article could encourage health care providers and urologists to apply acupuncture for managing pains of CP/CPPS with standard treatment.

Assessing attitudes toward and beliefs about pain among Chinese patients with chronic pain: validity and reliability of the Chinese version of the Pain Beliefs and Perceptions Inventory (ChPBPI).
Research consistently has evidenced the reliability and validity of the Pain Beliefs and Perceptions Inventory (PBPI). The instrument, however, has not been tested for its applicability and validity in non-Western populations. ⋯ These findings support the factorial validity of the scales of the ChPBPI, and its reliability and construct validity. Now clinically relevant beliefs about pain can be assessed among Chinese patients with chronic pain.

On behalf of the German chapter of the International Association for the Study of Pain (IASP) recommendations for German pain treatment services have been developed for the first time. The criteria were based on the IASP recommendations but adapted to the specific German situation. According to the structure and process criteria four different levels of pain treatment services can be distinguished. The aim of the recommendations is to serve as a guide for future development and implementation of pain therapy and quality assurance.
