Randomized Controlled Trial[Influence of lateral retinacular release on anterior knee pain following total knee arthroplasty].
To investigate the effect of lateral retinacular release on the clinical outcomes after total knee arthroplasty (TKA) without resurfacing of the patella. ⋯ Lateral retinacular release during primary TKA without resurfacing of the patella can reduce postoperative knee pain without increasing complications.

ReviewWhen pain hurts: Nociceptive stimulation induces a state of maladaptive plasticity and impairs recovery after spinal cord injury.
Spinal cord injury (SCI) is often accompanied by other tissue damage (polytrauma) that provides a source of pain (nociceptive) input. Recent findings are reviewed that show SCI places the caudal tissue in a vulnerable state that exaggerates the effects nociceptive stimuli and promotes the development of nociceptive sensitization. Stimulation that is both unpredictable and uncontrollable induces a form of maladaptive plasticity that enhances nociceptive sensitization and impairs spinally mediated learning. ⋯ Noxious input enhances tissue loss at the site of injury by increasing the extent of hemorrhage and apoptotic/pyroptotic cell death. Intrathecal lidocaine blocks nociception-induced hemorrhage, cellular indices of cell death, and its adverse effect on behavioral recovery. Clinical implications are discussed.

[Standardised pain assessment in cognitively impaired nursing home residents: Comparing the use of assessment tools in dementia care units and in integrated care units].
A large number of nursing home residents with cognitive impairments (CI) suffer from chronic pain, which is also discussed as a reason for challenging behavior. To assess pain in people with severe CI, the use of an observational pain instrument is recommended; for people without or with mild CI the gold standard is a self-rating instrument. It is unknown whether in German nursing homes pain assessment in residents with severe CI is actually conducted using observational instruments and which instruments are used. Because of different resident structure we assume that in dementia care units observational pain instruments are more often used than in integrated care units. The aim of this study was to investigate the conduction of pain assessments and the instruments used in both types of care units. ⋯ Especially in integrated units, a defined and consented method of pain assessment is important because of the differences in their residents' cognitive and verbal abilities. Appropriate education may help to improve this process.

Randomized Controlled Trial
Validity of Simplified Versus Standard Self-Report Measures of Pain Intensity in Preschool-Aged Children Undergoing Venipuncture.
There are inadequate age-specific data to support the use of current self-report pain scales in 3- and 4-year-old children. Most preschool-aged children also lack the necessary cognitive development to use standard scales. We aimed to evaluate the validity and feasibility of 2 novel simplified scales (Simplified Faces Pain Scale, S-FPS; Simplified Concrete Ordinal Scale, S-COS) for preschool-aged children. These simplified scales used a 2-step self-report method: children were first asked whether they have pain (yes/no); only if yes, then pain intensity was self-reported using a 3-point scale with visual aids signifying mild/moderate/severe. ⋯ Correlation with Face Legs Activity Cry Consolability was moderate to strong and cooperation rates were similar for all self-report scales. The simplified scales can improve and simplify pain assessment for 4-year-olds. Quantitative pain rating remains challenging for 3-year-olds.

Observational Study
Endogenous Pain Facilitation Rather Than Inhibition Differs Between People with Chronic Fatigue Syndrome, Multiple Sclerosis, and Controls: An Observational Study.
Commonalities in the core symptoms of fatigue and cognitive dysfunction experienced by chronic fatigue syndrome (CFS, also known as ME) and multiple sclerosis (MS) patients have been described. Many CFS and MS patients also experience chronic pain, which has been attributed to central sensitization in both groups of patients. However, the characteristics of pain in CFS and MS patients have not been compared. ⋯ We found differences in the characteristics of pain symptoms reported by patients with CFS and patients with MS, which suggest different underlying mechanisms. Specifically, overactive endogenous pain facilitation was characteristic of pain in patients with CFS but not in patients with MS, suggesting a greater role for central sensitization in CFS.
