To assess the effects of a 9-week yoga intervention on chronic nonspecific neck pain 12 months after completion. ⋯ A 9-week yoga intervention improved pain and neck-related disability for at least 12 months after completion. Sustained yoga practice seems to be the most important predictor of long-term effectiveness.

Comparative Study
Demand valve oxygen: a promising new oxygen delivery system for the acute treatment of cluster headache.
To show that demand valve oxygen is an effective acute treatment for cluster headache and to compare this oxygen delivery technique with standard cluster headache therapy of continuous flow oxygen. ⋯ Demand valve oxygen appears to be an effective acute treatment for cluster headache. All subjects became headache-free. Time to pain freedom was fast (average 12 minutes). The small number of study subjects does not allow a direct comparison of efficacy between demand valve oxygen and continuous high flow oxygen.

Intrathecal therapy (ITT) for cancer pain is characterized by high initial cost followed by low maintenance costs. Non-ITT pain management is associated with steadily increasing cumulative cost that can equal the cost of ITT over time. The intent of this modeling project is to identify factors associated with relatively rapid achievement of cost-benefit with ITT. ⋯ In selected patients on high-cost opioid regimens, ITT may become cost-beneficial within 6 months. Factors associated with earlier attainment of ITT cost-benefit include the use of parenteral therapy, high-dose opioids, and the use of nongeneric opioid products.

Patients with dementia, whose ability to provide self-report of pain is often impaired, are in crucial need of observers who can detect and judge the patients' pain-indicative behaviors appropriately, in order to initiate treatment. The facial display of pain promises to be especially informative for that purpose. The major aim of the study was to investigate, whether facial pain displays of patients with dementia can be as easily interpreted as facial displays of individuals without cognitive impairment and whether nurses have learned-through their professional training and work experience-to better read the facial display of pain compared with a control group. ⋯ Without further contextual information, "professional" observers do not show a superior competence in inferring pain in others by reading their facial display. Therefore, additional training seems needed to reliably prevent that pain goes unnoticed in patients with dementia.

Randomized Controlled Trial
Predicting response to pregabalin from pretreatment pain quality: clinical applications of the pain quality assessment scale.
The aim of this study is to assess the Pain Quality Assessment Scale (PQAS) in predicting pregabalin in peripheral neuropathic pain (NP). ⋯ Pretitration PQAS scores reliably predicted pregabalin responders in patients with NP.
