The objectives of this study were to evaluate the methodological quality of rigorous neuropathic pain assessment tools in applicable clinical studies, and determine the performance of screening tools for identifying neuropathic pain in patients with cancer. ⋯ We identified concordance between the clinician diagnosis and screening tool outcomes for LANSS, DN4 and PDQ in patients with cancer pain. Shortcomings in relation to standardized clinician assessment are likely to account for variation in screening tool sensitivity, which should include the use of the neuropathic pain grading system. Further research is needed to standardize and improve clinical assessment in patients with cancer pain. Until the standardization of clinical diagnosis for neuropathic cancer pain has been validated, screening tools offer a practical approach to identify potential cases of neuropathic cancer pain.

Comparative Study
Provoked Vestibulodynia: A Comparative Examination of Mental Health, Sleep, Sexual Functioning, and Relationship Adjustment.
Provoked vestibulodynia (PVD) is an idiopathic vulvar pain condition characterized by burning pain at the vaginal opening in response to contact or pressure. Previous research has established some of the psychosocial difficulties experienced by these patients, but direct comparisons with other pain conditions are needed. The purpose of this study was to compare women with PVD to those with postherpetic neuralgia and pain-free control participants. ⋯ These results indicate that women with PVD and PHN experience similar mental health difficulties, but women with PHN experience more severe impact on their day-to-day functioning and mood. These results support the classification of PVD as a chronic pain condition, as both the pain groups differed from pain-free control participants on a range of measures. Finally, the presence of mental health difficulties and poorer sexual functioning highlights the importance of conducting biopsychosocial pain assessments.

Non-freezing cold injury develops after sustained exposure to cold temperatures, resulting in tissue cooling but not freezing. This can result in persistent sensory disturbance of the hands and feet including numbness, paraesthesia and chronic pain. Both vascular and neurological aetiologies of this pain have been suggested but remain unproven. ⋯ Chronic non-freezing cold injury is a disabling neuropathic pain disorder due to a sensory neuropathy. Why some individuals develop an acute painful sensory neuropathy on sustained cold exposure is not yet known, but individuals of African descent appear vulnerable. Screening tools, such as the DN4 questionnaire, and treatment algorithms for neuropathic pain should now be used in the management of these patients.

Chronic pain is one of the most reported health problems in patients suffering from spinal cord injuries and is described by the patients as one of the most burdensome sequelae of paraplegia. Various types of pain, such as nociceptive, neuropathic and other types of pain can occur. ⋯ These aspects necessitate a multimodal pain management approach in this patient group. This article presents an overview of the occurrence, importance and pathophysiology of chronic pain following spinal cord injury as well as diagnostic and therapeutic approaches.

Numerous publications describe chronic pain following surgery in both adults and children. However, data in the paediatric population are still sparse and both prevalence of chronic pain after surgery and risk factors of this complication still undetermined. ⋯ Patients scheduled for spine surgery and presenting with preoperative pain should be considered at risk of chronic pain after surgery and managed accordingly by the chronic and/or acute pain team. Postoperative opioid consumption should be lowered as possible by using multimodal analgesia and regional analgesia such as postoperative epidural analgesia.
