Central pain syndromes associated with damage to the thalamic sensory relay nuclei have been described predominantly in the stroke literature; however, pain syndromes associated with thalamic neoplasms are much less common. We describe a woman with dyspareunia secondary to vaginal allodynia as the presenting sign of a left thalamic juvenile pilocytic astrocytoma. ⋯ We believe that this is the first reported case of isolated vaginal allodynia associated with a thalamic neoplasm or any other structural pathology of the central nervous system. Dyspareunia secondary to vaginal allodynia as the presenting sign of a left thalamic juvenile pilocytic astrocytoma is reported, in a rare case underscoring that thalamic pathology including neoplasms should be considered in evaluating patients with longstanding and unexplained pain syndromes.

Review Meta Analysis
Acceptance-based interventions for the treatment of chronic pain: a systematic review and meta-analysis.
Acceptance-based interventions such as mindfulness-based stress reduction program and acceptance and commitment therapy are alternative therapies for cognitive behavioral therapy for treating chronic pain patients. To assess the effects of acceptance-based interventions on patients with chronic pain, we conducted a systematic review and meta-analysis of controlled and noncontrolled studies reporting effects on mental and physical health of pain patients. All studies were rated for quality. ⋯ It is recommended to focus on therapies that integrate mindfulness and behavioral therapy. Acceptance-based therapies have small to medium effects on physical and mental health in chronic pain patients. These effects are comparable to those of cognitive behavioral therapy.

Randomized Controlled Trial Comparative Study Clinical Trial
A randomised, five-parallel-group, placebo-controlled trial comparing the efficacy and tolerability of analgesic combinations including a novel single-tablet combination of ibuprofen/paracetamol for postoperative dental pain.
Combination analgesia is often recommended for the relief of severe pain. This was a double-blind, 5-arm, parallel-group, placebo-controlled, randomised, single-dose study designed to compare the efficacy and tolerability of a novel single-tablet combination of ibuprofen and paracetamol with that of an ibuprofen/codeine combination, and a paracetamol/codeine combination, using the dental impaction pain model. Subjects with at least 3 impacted third molars and experiencing moderate to severe postoperative pain were randomised to receive: 1 or 2 tablets of a single-tablet combination of ibuprofen 200mg/paracetamol 500mg; 2 tablets of ibuprofen 200 mg/codeine 12.8mg; 2 tablets of paracetamol 500mg/codeine 15mg; or placebo. ⋯ Adverse events were uncommon during this study and treatment emergent adverse events were statistically significantly less frequent in the groups taking the ibuprofen/paracetamol combination compared with codeine combinations. In conclusion, 1 or 2 tablets of a single-tablet combination of ibuprofen 200mg/paracetamol 500mg provided highly effective analgesia that was comparable with, or superior to, other combination analgesics currently indicated for strong pain. A single-tablet combination of ibuprofen 200mg/paracetamol 500mg provides highly effective analgesia, comparable or superior to other combination analgesics indicated for strong pain.

Quantitative sensory testing (QST) is an instrument to assess positive and negative sensory signs, helping to identify mechanisms underlying pathologic pain conditions. In this study, we evaluated the test-retest reliability (TR-R) and the interobserver reliability (IO-R) of QST in patients with sensory disturbances of different etiologies. In 4 centres, 60 patients (37 male and 23 female, 56.4±1.9years) with lesions or diseases of the somatosensory system were included. ⋯ We conclude that standardized QST performed by trained examiners is a valuable diagnostic instrument with good test-retest and interobserver reliability within 2days. With standardized training, observer bias is much lower than random variance. Quantitative sensory testing performed by trained examiners is a valuable diagnostic instrument with good interobserver and test-retest reliability for use in patients with sensory disturbances of different etiologies to help identify mechanisms of neuropathic and non-neuropathic pain.
