Previous studies have shown that protein kinase M zeta (PKMζ), a brain-specific isoform of protein kinase C, is involved in the central processing of nociception in several pain models by using a synthetic zeta inhibitory peptide. In the present study, we investigated whether PKMζ contributes to the pathogenesis of postsurgical pain using both conditional and conventional PKMζ knockout mice. Our results showed that the expression of PKMζ in anterior cingulate cortex, but not spinal cord, of the conditional PKMζ knockout mice was inhibited following tamoxifen injection. ⋯ Moreover, the expression of PKMζ was inhibited in both anterior cingulate cortex and spinal cord of the conventional PKMζ knockout mice. And there were no significant differences in the development of postsurgical pain among wild-type, heterozygous, and homozygous conventional PKMζ knockout mice. These data suggest that PKMζ is not required for the development of postsurgical pain after plantar incision.

The International Costs and Utilities Related to Osteoporotic fractures Study is a multinational observational study set up to describe the costs and quality of life (QoL) consequences of fragility fracture. This paper aims to estimate and compare QoL after hip, vertebral, and distal forearm fracture using time-trade-off (TTO), the EuroQol (EQ) Visual Analogue Scale (EQ-VAS), and the EQ-5D-3L valued using the hypothetical UK value set. ⋯ The approach to derive QoL markedly influences the estimated QoL impact of fracture. Therefore the choice of approach may be important for the outcome and interpretation of cost-effectiveness analysis of fracture prevention.

Observational StudyThe Rotterdam Elderly Pain Observation Scale (REPOS) is reliable and valid for non-communicative end-of-life patients.
In palliative care, administration of opioids is often indispensable for pain treatment. Pain assessment may help recognize pain and guide treatment in non-communicative patients. In the Netherlands the Rotterdam Elderly Pain Observation Scale (REPOS) is recommended to this aim, but not yet validated. Therefore the objective of this study was to validate the REPOS in non-communicative or unconscious end-of-life patients. ⋯ This study demonstrates that the REPOS has promising psychometric properties for pain assessment in non-communicative end-of-life patients. Its application may be of additional value to relieve suffering, including pain, in palliative care.

Headache disorders are both common and burdensome but, given the many people affected, provision of health care to all is challenging. Structured headache services based in primary care are the most efficient, equitable and cost-effective solution but place responsibility for managing most patients on health-care providers with limited training in headache care. The development of practical management aids for primary care is therefore a purpose of the Global Campaign against Headache. This manuscript presents an outcome measure, the Headache Under-Response to Treatment (HURT) questionnaire, describing its purpose, development, psychometric evaluation and assessment for clinical utility. The objective was a simple-to-use instrument that would both assess outcome and provide guidance to improving outcome, having utility across the range of headache disorders, across clinical settings and across countries and cultures. ⋯ With demonstrated validity and clinical utility across disorders, cultures and settings, HURT is available for clinical and research purposes.

Randomized Controlled TrialSafety and efficacy of platelet-rich plasma in treatment of carpal tunnel syndrome; a randomized controlled trial.
Carpal tunnel syndrome is the most common peripheral entrapment neuropathy, for which conservative treatments are the first measures taken. However, these measures are not usually sufficient. Recently major attention has been drawn to platelet-rich plasma for its possible effects on axon regeneration and neurological recovery. Although few studies have evaluated the effects of this treatment in carpal tunnel syndrome, further investigation is required to reach concrete conclusion. ⋯ The findings of this study showed that in a relatively short period of time after treatment, a single injection of platelet-rich plasma in the wrist does not significantly add to the effects of conservative treatment with wrist splints, in regards to the women pain and symptom severity, functional status and electrophysiological parameters.
