Comparative Study
Quantitative sensory testing profiles in chronic back pain are distinct from those in fibromyalgia.
Alterations in the central nervous system leading to higher pain sensitivity have been shown in both chronic back pain (CBP) and fibromyalgia syndrome (FMS). The aim of this study was to disclose commonalities and differences in the pathophysiology of FMS and CBP. ⋯ FMS patients showed increased sensitivity for different pain modalities at all measured body areas, suggesting central disinhibition as a potential mechanism. CBP participants in contrast, showed localized alterations within the affected segment possibly due to peripheral sensitization.

Randomized Controlled Trial
A randomized, controlled study to investigate the analgesic efficacy of single doses of the cannabinoid receptor-2 agonist GW842166, ibuprofen or placebo in patients with acute pain following third molar tooth extraction.
To evaluate the postoperative analgesic efficacy of GW842166, a noncannabinoid CB2 agonist, in patients undergoing third molar tooth extraction. ⋯ In comparison to ibuprofen, single doses of GW842166 (100 and 800 mg) failed to demonstrate clinically meaningful analgesia in the setting of acute dental pain.

The link between chronic back pain and disability is well established. Despite this, the literature also reflects an inconsistency in methods of assessing disability, as studies interchangeably use self-report measures, clinical tests, and electronic monitoring. The purpose of this study was to conduct a multimethod comparison of disability measures to identify similarities and differences in the constructs measured by each. ⋯ The results indicate substantial differences in the types of variables that predict disability when measured through 3 different methods. This is suggestive of differences in the constructs measured by each type of disability assessment. The implications for researchers who assess predictors of disability and clinicians who use disability measures in their assessment of patients are that the measures of disability they select should be carefully matched to the proposed purposes. Strong theoretical and practical considerations support using electronic ambulatory monitoring in future research and clinical service.

Randomized Controlled Trial Comparative Study
A comparative study of 2 manual-based self-help interventions, acceptance and commitment therapy and applied relaxation, for persons with chronic pain.
The aim of this study was to compare 2 self-help-based interventions; a coping-oriented approach, applied relaxation (AR) and an acceptance-oriented approach, acceptance and commitment therapy (ACT), for persons with chronic pain. ⋯ A manual-based self-help intervention with weekly therapist support in an ACT format adds value to the treatment repertoire for persons suffering with chronic pain.

Analgesic use is common but remains poorly described among human immunodeficiency virus (HIV)-infected persons in the highly active antiretroviral therapy era. ⋯ In the highly active antiretroviral therapy era, up to 15% of HIV Outpatient Study patients used prolonged analgesic therapy each year. Variables associated with the initiation of prolonged analgesia included HIV and non-HIV-related factors.
