Review Meta Analysis Guideline
Dutch Multidisciplinary Guideline for Invasive Treatment of Pain Syndromes of the Lumbosacral Spine.
When conservative therapies such as pain medication or exercise therapy fail, invasive treatment may be indicated for patients with lumbosacral spinal pain. The Dutch Society of Anesthesiologists, in collaboration with the Dutch Orthopedic Association and the Dutch Neurosurgical Society, has taken the initiative to develop the guideline "Spinal low back pain," which describes the evidence regarding diagnostics and invasive treatment of the most common spinal low back pain syndromes, that is, facet joint pain, sacroiliac joint pain, coccygodynia, pain originating from the intervertebral disk, and failed back surgery syndrome. ⋯ The guideline committee concluded that the categorization of low back pain into merely specific or nonspecific gives insufficient insight into the low back pain problem and does not adequately reflect which therapy is effective for the underlying disorder of a pain syndrome. Based on the guideline "Spinal low back pain," facet joint pain, pain of the sacroiliac joint, and disk pain will be part of a planned nationwide cost-effectiveness study.

Randomized Controlled Trial
Relevance of Water Temperature, Apparatus, and Age to Children's Pain during the Cold Pressor Task.
Effective use of experimental pain in research depends on a thorough understanding of factors influencing their use. Although studies using the cold pressor task (CPT) have critically advanced our knowledge of pain mechanisms, assessment, and management in adults and children, the impact of identified methodological variability in its use is not known (ie, water temperature and apparatus); furthermore, whether methodological variations differentially impact children across development. ⋯ These results provide critically important information about water temperature, apparatus, and child age on CPT pain responding. It informs design of future CPT studies and directs consideration of methodological variability and child age when interpreting study findings.

Open discectomy remains the standard of treatment for patients with lumbar radicular pain secondary to a prolapsed intervertebral disc. Open discectomy performed in patients with small, contained herniations may result in poor outcomes. The various techniques of percutaneous disc decompression (PDD) have been developed to address this population. ⋯ Nucleoplasty and Dekompressor have a weak positive recommendation for the treatment of patients with lumbar radicular pain. There is no role for provocative discography in this group of patients, although the evidence for a selective nerve root injection or an intra-op discogram is inconclusive.

Pain drawings have frequently been used for clinical information and research. The aim of this study was to investigate intra- and inter-rater reliability of area measurements performed on pain drawings. Our secondary objective was to verify the reliability when using computers with different screen sizes, both with and without mouse hardware. ⋯ The inter-rater reliability was also high. No significant differences were observed when using different screen sizes or when using or not using the mouse hardware. This suggests that the precision of these measurements is acceptable for the use of this method as a measurement tool in clinical practice and research.

Whether psychological factors such as anxiety and pain catastrophizing levels influence the expression of endogenous analgesia in general and, more specifically, the conditioned pain modulation (CPM) response is still under debate. It may be assumed that other psychological characteristics also play a role in the CPM response. The neurotransmitters serotonin, dopamine, and norepinephrine are involved both in CPM, as well as personality traits such as harm avoidance (HA), novelty seeking (NS), and reward dependence (RD), which can be obtained by the Tridimensional Personality Questionnaire (TPQ). However, the associations between these traits (HA, NS, and RD) with endogenous analgesia revealed by CPM have not yet been explored. ⋯ The relationship between the capacity of endogenous analgesia and the tendency to avoid aversive experience can be explained by mutual mechanisms involving similar neurotransmitters or brain areas. These findings illuminate the key role of harm avoidance obtained by the TPQ in determining the characteristics of pain modulation profile.
