Randomized Controlled Trial
Mindfulness-based Cognitive Therapy for the Treatment of Headache Pain: A Pilot Study.
This pilot study reports the findings of a randomized controlled trial (RCT) investigating the feasibility, tolerability, acceptability, and initial estimates of efficacy of mindfulness-based cognitive therapy (MBCT) compared to a delayed treatment (DT) control for headache pain. It was hypothesized that MBCT would be a viable treatment approach and that compared to DT, would elicit significant improvement in primary headache pain-related outcomes and secondary cognitive-related outcomes. ⋯ This study empirically examined MBCT for the treatment of headache pain. Results indicated that MBCT is a feasible, tolerable, acceptable, and potentially efficacious intervention for patients with headache pain. This study provides a research base for future RCTs comparing MBCT to attention control, and future comparative effectiveness studies of MBCT and cognitive-behavioral therapy.

Randomized Controlled Trial
The Safety of Liposome Bupivacaine, A Novel Local Analgesic Formulation.
Pooled safety data from 10 randomized, double-blind studies of liposome bupivacaine, a novel local analgesic formulation, were examined. ⋯ Liposome bupivacaine exhibited acceptable tolerability across 823 patient exposures.

Chronic opioid therapy (COT) is associated with various adverse outcomes, especially at higher doses, yet little is known about predictors of sustained higher-dose COT. This study aimed to ascertain, among higher-dose COT patients, the association of patient-perceived pros and cons of opioids with continued higher-dose use 1 year later. ⋯ The large majority of patients continued using higher-dose opioids regardless of baseline characteristics. These findings suggest the difficulty of reducing opioid dose among chronic higher-dose opioid users.

The aims of this study were to (1) examine the pattern of experimental pain responses in the affected and nonaffected extremities in patients with shoulder pain and (2) explore the intraindividual association between sensitization states derived from experimental pain testing. ⋯ Collectively, experimental pain responses supported peripheral and central sensitization in response to pressure and thermal stimuli. No clear association was made between individuals exhibiting peripheral or central sensitization, thus suggesting heterogeneity in pain processing in this clinical population.

Randomized Controlled Trial Multicenter Study
NGX-4010, a Capsaicin 8% Dermal Patch, for the Treatment of Painful HIV-associated Distal Sensory Polyneuropathy: Results of a 52-Week Open-Label Study.
To evaluate the efficacy, safety, and tolerability of repeated NGX-4010 treatments in the open-label extension phase of a 52-week study in patients with neuropathic pain due to HIV-associated distal sensory polyneuropathy (HIV-DSP). ⋯ Repeated NGX-4010 treatments were generally well tolerated and resulted in consistent reductions in HIV-DSP-associated pain and improvement in patient-reported outcomes.
