PainDETECT is a self-report questionnaire that can be used to identify features of neuropathic pain. A proportion of patients with knee osteoarthritis (OA) score highly on the PainDETECT questionnaire. This study aimed to determine whether those with a higher "positive neuropathic" score on the PainDETECT questionnaire also had greater pain, hypersensitivity, and reduced function compared with individuals with knee OA with lower PainDETECT scores. ⋯ This study identified a specific subgroup of people with knee OA who exhibited PainDETECT scores in the "positive neuropathic" category. These individuals experienced increased levels of pain, widespread, multimodality hyperalgesia, and greater functional impairment than the remaining cohort. Identification of OA patients with this pain phenotype may permit more targeted and effective pain management.

Randomized Controlled Trial
Mindfulness-Based Cognitive Therapy and Persistent Pain in Women Treated for Primary Breast Cancer: Exploring Possible Statistical Mediators - Results from a Randomized Controlled Trial.
The aim of this study was to investigate possible statistical mediators in a randomized controlled trial of mindfulness-based cognitive therapy (MBCT) on pain intensity in women treated for primary breast cancer. ⋯ The results of the present study may have clinical implications. An increased focus on the proposed mediators may optimize the clinical use of MBCT for persistent pain in women treated for breast cancer.

Randomized Controlled Trial
Efficacy of Postoperative Analgesia of Local Ketamine Wound Instillation Following Total Thyroidectomy; A Randomized, Double-blind, Controlled-clinical Trial.
Total thyroidectomy is recommended as a line of management of thyroid cancer in many cases. Our aim was to compare postoperative analgesic effect of local ketamine 1 mg/kg instilled in the wound to that of intramuscular (IM) ketamine and placebo after total thyroidectomy. ⋯ Local wound ketamine instillation provided superior postoperative analgesia with lower incidence of side effects in comparison with IM ketamine and placebo following total thyroidectomy.

To evaluate whether orexin receptor antagonism with filorexant provides pain relief in patients with painful diabetic neuropathy (PDN). ⋯ These data do not provide evidence for the efficacy of nightly filorexant for the treatment of PDN.

Review Meta Analysis
Lumbar Tactile Acuity in Patients With Low Back Pain and Healthy Controls: Systematic Review and Meta-Analysis.
Diminished tactile acuity in chronic non-neuropathic pain syndromes has been attributed to central pain processing and cortical reorganization. The latter was recently targeted in clinical trials that demonstrated no clear advantages over traditional approaches for the reduction of nonspecific low back pain (LBP). The aim of this systematic review and meta-analysis was to summarize the current evidence on tactile acuity in LBP and pain-free controls. ⋯ A gap of knowledge regarding tactile acuity in populations with acute and chronic non-neuropathic LBP needs to be addressed in future research as this may significantly help the understanding of the causality of tactile acuity alterations.
