Randomized Controlled Trial
Using eye movements to investigate selective attention in chronic daily headache.
Previous research has demonstrated that chronic pain is associated with biased processing of pain-related information. Most studies have examined this bias by measuring response latencies. The present study extended previous work by recording eye movement behaviour in individuals with chronic headache and in healthy controls while participants viewed a set of images (i.e., facial expressions) from 4 emotion categories (pain, angry, happy, neutral). ⋯ Both participant groups showed a significantly greater bias to maintain gaze longer on happy images, relative to pain, angry, and neutral images. Results are consistent with a pain-related bias that operates in the orienting of attention on pain-related stimuli, and suggest that chronic pain participants' attentional biases for pain-related information are evident even when other emotional stimuli are present. Pain-related information-processing biases appear to be a robust feature of chronic pain and may have an important role in the maintenance of the disorder.

Observational Study
Overgeneral autobiographical memory in patients with chronic pain.
Overgenerality and delay of the retrieval of autobiographical memory (AM) are well documented in a range of clinical conditions, particularly in patients with emotional disorder. The present study extended the investigation to chronic pain, attempting to identify whether the retrieval of AM in patients with chronic pain tends to be overgeneral or delayed. ⋯ The retrieval of AM in patients with chronic pain tends to be overgeneral and delayed, and the retrieval style of AM may be contributed to negative emotions and chronic pain conditions.

Randomized Controlled TrialA cognitive behavioral smoking abstinence intervention for adults with chronic pain: a randomized controlled pilot trial.
Current evidence suggests it may be difficult for patients with chronic pain to quit smoking and, based on previous formative work, a 7-session individual and group-based cognitive behavioral (CB) intervention was developed. The primary aim of this randomized controlled pilot trial was to test the hypothesis that abstinence at month 6 would be greater among patients with chronic pain who received the CB intervention compared to a control condition. Upon admission to a 3-week interdisciplinary pain treatment (IPT) program, patients were randomized to receive the CB intervention (n=30) or the control condition (n=30). ⋯ At week 3, a significant group by time interaction effect was found where the CB patients experienced greater improvements in self-efficacy from baseline compared to the control group (P=.002). A greater proportion of patients randomized to the CB group completed the IPT program (P=.052). The findings of this pilot trial suggest that integration of a CB-based smoking abstinence intervention into ongoing pain therapy may be an effective treatment for smokers with chronic pain.

Pain in the spine is the most frequently described pain problem in primary care, afflicting at least 54 million Americans. When spinal pain becomes chronic, the prognosis for recovery is poor, often leading to disability and reduced quality of life. Clinical treatment is inadequate, often focusing on physical pathology alone. ⋯ Five of the six BPP subscales had a significant association with quality of life, chronic pain, and disability with the thought of disease progression being a strong factor for most of the clinical outcome variables. By identifying BPP, clinicians can provide appropriate treatments to improve individuals' quality of life and prevent further disability. Further study using the BPP to guide CBT is needed.

Randomized Controlled Trial Comparative Study
Percutaneous vertebroplasty compared with conservative treatment in patients with chronic painful osteoporotic spinal fractures.
The efficacy of percutaneous vertebroplasty (PVP) for patients with chronic painful osteoporotic compression fractures remains unknown. The purpose of this study was to compare the efficacy of PVP and conservative treatment (CT) for pain relief and functional outcome in patients with chronic compression fractures and persistent pain. Ninety-six patients with chronic compression fractures confirmed by MRI and persistent severe pain for 3 months or longer were prospectively randomly assigned to undergo PVP (n=46, Group A) or CT (n=50, Group B). ⋯ Pain relief and functional outcomes were significantly better in Group A than in Group B, as determined by visual analogue scale scores, Oswestry Disability Index scores, and Roland Morris Disability scores at 1 week, 1 month, 3 months, 6 months and 1 year (all p<0.001). The final clinical follow-up assessment indicated complete pain relief in 39 Group A patients and 15 Group B patients (p<0.001). PVP for patients with chronic compression fractures and persistent severe pain was associated with better pain relief and improved functional outcomes at 1 year compared to CT.
