Symptoms of central sensitization (CS) have been described in patients with chronic spinal pain (CSP). Although a gold standard to diagnose CS is lacking, psychophysical pain measures are often used. The Central Sensitization Inventory (CSI) is proposed as an alternative method and indirect tool for the evaluation of CS symptomatology. The aim of the current study was to evaluate the convergent validity of the CSI by investigating the association with psychophysical pain measures and self-reported measures of current pain intensity, quality of life, disability, and catastrophizing in CSP patients. ⋯ The CSI was weakly associated with PPTs and not with CPM efficacy in CSP patients. Moderate to strong associations were found with current pain intensity, quality of life, disability, and catastrophizing. The current results illustrate that the CSI does not reflect a direct measure of CS, yet is a representation of general distress, possible originating from CS symptoms.

Neuropathic pain is a frequent consequence of cancer pain. Quite often, in the end stage, it is difficult to discern its presence and delineate its characteristics in the context of painful cancer complications. The aim of this study was to compare the diagnostic accuracy of the Douleur Neuropathique en 4 Questions (DN4) and painDETECT questionnaires, which were translated to the patient's native language, for the diagnosis of peripheral neuropathic pain in oncology patients. ⋯ At standard cutoff values, the DN4 and painDETECT questionnaires, despite having been translated to the patient's native language, failed to adequately discriminate between neuropathic and non-neuropathic pain in our end-stage cancer patients.

Personalized Pain Goal as an Outcome Measure in Routine Cancer Pain Assessment.
There is currently no universally accepted outcome measure in cancer pain management. The personalized pain goal (PPG) has been shown to be a relevant outcome measure. We examined its use in routine outpatient practice and compared it with the clinically important difference (CID, ≥2 points or 30%), a pain outcome measure frequently used in several clinical studies. ⋯ PPG was successfully completed in the vast majority of patients, suggesting its feasibility as a pain outcome measure in routine clinical practice. Higher baseline pain intensity, depression, opioid dose, and number of adjuvant analgesics were independent predictors of poor pain relief. Further research is needed to further evaluate its clinical importance in cancer pain management.

Traumatic brain injury refers to a broad range of neurological, cognitive, and emotional factors that result from the application of an external force to the head. Individuals recovering from traumatic brain injury will frequently experience acute and chronic pain. ⋯ This review presents evidence that pain is common after traumatic brain injury. However, while there are many potential mechanisms explaining this problem such as neuroinflammation, excitotoxicity, and axonal degeneration, we have no clear understanding of which of them contribute in individual patients. The authors highlight the priorities for research that will expand our knowledge and that may lead to the rational design of therapies that both reduce pain and provide optimal overall outcomes after traumatic brain injury.

The aim was to validate the short PTSD-8 scale against the Structured Clinical Interview (SCID-1) for post-traumatic stress disorder and to test the latent structure of post-traumatic stress disorder in chronic pain patients. ⋯ Overall, the results showed that the PTSD-8 is a valid short screening tool to assess possible post-traumatic stress disorder among patients with chronic pain. In addition, the PTSD-8 scale comprises all of the upcoming ICD-11 post-traumatic stress disorder symptoms within its eight items. Thus, the PTSD-8 is likely also to measure the proposed ICD-11 post-traumatic stress disorder.
