Chronic neuropathic pain (NP) is a well-known phenomenon, whereas acute neuropathic pain is increasingly recognized. Both are potentially difficult for a nonspecialist to diagnose. The Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) and DN4 scales are screening tools developed to identify chronic NP. We aimed to evaluate and compare their performance in 2 different populations: outpatients with chronic pain, and inpatients with acute postoperative pain. ⋯ Although the LANSS performed better than the DN4 in the chronic population, both tools performed less well than published literature, demonstrating the importance of evaluating screening tools in the proposed patient population. There may be potential for using these questionnaires to identify acute NP.

To evaluate the properties of the Pain Catastrophizing Scale (PCS) from a Rasch paradigm. ⋯ The results of this secondary analysis suggest that the PCS can be appropriately evaluated as an interval-level scale when the composite 13-item score is considered, as has been standard practice to date. Implications for clinical and research use are discussed.

Associations between 4 forms of pain (ie, arthritis, severe/frequent headaches, chronic spinal pain, and other chronic pain) and borderline personality disorder (BPD) symptoms were investigated in the general population. ⋯ This is the first study to demonstrate that BPD symptoms are positively associated with chronic spinal pain, severe/frequent headaches, and other chronic pain conditions in a sample representative of the general population. The findings also suggest that relationships between remitted pain conditions and BPD symptoms warrant additional study.

Review Meta Analysis
A systematic review and meta-analysis of yoga for low back pain.
To systematically review and meta-analyze the effectiveness of yoga for low back pain. ⋯ This systematic review found strong evidence for short-term effectiveness and moderate evidence for long-term effectiveness of yoga for chronic low back pain in the most important patient-centered outcomes. Yoga can be recommended as an additional therapy to chronic low back pain patients.

To test whether the prognostic definition of chronic pain, which has previously been applied in specific anatomic areas, performed well in a cohort of older adults with a range of musculoskeletal pain sites. ⋯ The prognostic approach to defining chronic pain is suitable for use in older adults consulting primary care with musculoskeletal pain at a range of sites, but new cutoffs are needed to allow for the higher risk profile in this group. An adapted version of this method may also have the potential for application directly within the clinical consultation.
