Cutting is the most common method of non-suicidal self-injury (NSSI) to reduce inner tension in patients with Borderline Personality Disorder (BPD). Aim of this study was to compare pain perception induced by an incision and by application of a surrogate model for sharp mechanical pain (a non-invasive "blade") in BPD. ⋯ Patients with Borderline Personality Disorder (BPD) who engage in non-suicidal self-injury (NSSI) report less pain in response to phasic nociceptive stimuli. In comparing an invasive pain stimulus to phasic nociceptive stimuli in BPD patients, the "blade" as non-invasive surrogate model for sharp mechanical pain in psychiatric patients is used. In contrast to healthy volunteers, BPD patients do not report significant affective ratings and specifically display a reduced sensory component for sharpness.

Observational Study
Predictors of treatment outcome in children with medically unexplained pain seeking primary care: A prospective cohort study.
Medically unexplained pain in children and adolescents is a common and increasing health care problem. Primary care is usually the first point of contact for these patients. It is the overall objective of this study to investigate treatment outcome of medically unexplained pain in paediatric primary care and to identify predictors of treatment failure. ⋯ This study investigates the treatment outcome of medically unexplained pain in paediatric primary care. Individuals with a higher emotional pain burden at the first visit and those without positive treatment response after 3 months are at increased risk for treatment failure. Therefore, a stepped-care approach seems warranted. After an insufficient primary care trial of 3 months, patients should be transferred to pain specialists for a more intense treatment.

Randomized Controlled Trial Clinical Trial
Differences in Long-Term Physical Activity Trajectories among Individuals with Chronic Widespread Pain: A Secondary Analysis of a Randomized Controlled Trial.
Little is known about long-term physical activity (PA) maintenance in those with chronic widespread pain (CWP) following an exercise intervention. This study examined PA over time to identify the existence and characteristics of subgroups following distinct PA trajectories. ⋯ Chronic pain can be a major barrier to engaging in exercise, a popular self-management strategy. Our findings identify three distinct long-term physical activity trajectories for individuals receiving the same exercise intervention. This suggests an approach by health care providers which identifies individuals who would benefit from additional support to enhance initiation and long-term physical activity maintenance could deliver better outcomes for such patients.

Widespread pain is a common comorbidity in several chronic diseases and is suspected to be caused by pain resulting from the underlying disease that has provoked a state of central sensitization. However, this argument is currently limited by evidence that has insufficiently captured the temporal nature of the relationship between diagnosis of the underlying disease and onset of widespread pain. The aim of this study was to investigate if patients with rheumatoid arthritis (RA), endometriosis or inflammatory bowel disease (IBD), have a higher risk of developing widespread pain (fibromyalgia or chronic widespread pain [CWP]). ⋯ We show that RA, endometriosis and IBD predisposes for later fibromyalgia and CWP, a common hypothesis previously difficult to verify due to lack of longitudinal data. The results inform further research regarding the aetiology of fibromyalgia and CWP and stress the need of clinical focus on the pain itself in chronic diseases with pain as a symptom.

As a complex multidimensional construct, fatigue may play an important role in the physical and psychosocial functioning of youth with chronic pain. Based on a model previously tested in adults, the current study similarly utilized patient-reported outcomes measurement system (PROMIS) to examine how fatigue contributes to functional outcomes for youth with chronic pain. The model tested self-reported ratings of pain intensity, depressive symptoms and sleep disturbance as predictors of outcomes (mobility, pain-related interference and school functioning) as mediated by ratings of fatigue. ⋯ This cross-sectional study highlights fatigue as a potential clinical target by applying a path analytic model to understand its possible significance and distinction from overlapping constructs such as pain intensity, depression and sleep disturbance. Further study of fatigue may be important in understanding its importance in treatment of paediatric chronic pain.
