The author discusses the general problem of the small but significant population of people in whom pain persists for months or years after a precipitating event, such as a hand injury. The nature of pain, the perception of pain, and characteristics of chronic pain patients are discussed, as well as evaluation and treatment of chronic pain.

This report discusses the general problem of the analysis of data that could include missing values. In the palliative care setting, the data may not be missing at random, but instead be related to the outcome of interest, and therefore the use of standard statistical procedures may be problematic. This study summarizes differing results that were found when using three simple methods for estimating missing data in an example data set testing for differences in the use of morphine or methadone for relief of pain. Differences in the conclusions are discussed and recommendations are made to improve the reporting of studies with missing data.

Children with physical, psychological and sensorial disabilities are known to be more vulnerable to violence and maltreatment, or to be at a greater risk of these forms of abuse. Violence and maltreatment of children with disabilities is part of the general problem of child maltreatment, which is still under-researched and little known as a whole; prevention, in particular, has received little attention. Preventing violence and maltreatment against children with disabilities means preventing physical pain, emotional suffering, difficulties in integration and sequelae additional to those already experienced by children due to their disability, in addition to avoiding great expense to the community. This article presents a review of the literature published in the last 10 years on the various primary and secondary prevention strategies that have taken place in developed countries, with the aim of bringing the subject to public attention, especially that of health professionals, and of serving as a basis for the planning of future research lines and prevention strategies.

Cold extremities have been noted in non-walking children with cerebral damage compared with healthy controls. Whether this is a general problem in children with cerebral palsy (CP) and associated with other symptoms is unknown. This study describes accompanying symptoms such as cold extremities, constipation, pain, sleeping disorders and impaired well-being in children with CP as well as treatment the children have undergone. Associations between cold extremities and other symptoms borne by the children were analysed and discussed. From information in postal surveys received from parents of children with CP, 107 children (60 boys and 47 girls) aged 5-13 years, mean 11 years 8 months (SD 2 years 11 months), were described and analysed. Besides neurological impairments, many children had cold extremities and pain, sleeping disorders, constipation, and impaired well-being. Most children had had one or more of these symptoms for over 1 year but the symptoms were largely untreated. Non-walkers generally had more symptoms than walkers. Although pain, constipation, and sleeping disorders may have different underlying causes in children with CP, these symptoms might also be mediated or aggravated by dysfunction in the autonomic nervous system. To improve the child's well-being, early recognition and treatment of accompanying symptoms is important.

Difficulties in emotion perception are commonly observed in autism spectrum disorder. However, it is unclear whether these difficulties can be attributed to a general problem of relating to emotional states, or whether they specifically concern the perception of others' expressions. This study addressed this question in the context of pain, a sensory and emotional state with strong social relevance. We investigated pain evaluation in self and others in 16 male individuals with autism spectrum disorder and 16 age- and gender-matched individuals without autism spectrum disorder. Both groups had at least average intelligence and comparable levels of alexithymia and pain catastrophizing. We assessed pain reactivity by administering suprathreshold electrical pain stimulation at four intensity levels. Pain evaluation in others was investigated using dynamic facial expressions of shoulder patients experiencing pain at the same four intensity levels. Participants with autism spectrum disorder evaluated their own pain as being more intense than the pain of others, showing an underestimation bias for others' pain at all intensity levels. Conversely, in the control group, self- and other evaluations of pain intensity were comparable and positively associated. Results indicate that emotion perception difficulties in autism spectrum disorder concern the evaluation of others' emotional expressions, with no evidence for atypical experience of own emotional states.
