To test whether mechanical hyperalgesia is associated with multiple idiopathic pain disorders (IPDs) and whether this relationship is independent of the confounding effects of psychosocial factors. ⋯ The dose-response relationship between TPs and IPDs needs further investigation to determine the temporal nature of these relationships and to disentangle the complex gene-environment relationships that may influence the occurrence of multiple IPDs.

This study examined which parents report to be solicitous or discouraging in response to their child's pain, and when they do so. ⋯ The findings of the current study highlight the importance of parental catastrophizing in explaining parental behavioural tendencies in response to their child in pain. Further, reported behaviours were found to vary across pain situations, attesting to the importance of studying parental behaviour 'in context'.

Little is known about the communication of everyday pain between young children and their parents, i.e. when children experience pain resulting from minor injury or illness that occur in everyday life. This study aimed to gain an in-depth understanding of how parents make sense of their young children's expression of everyday pains and how they respond. ⋯ These findings suggest that parents have well developed, although personal, ways of recognizing and responding to their children's communication of pain, but also experience uncertainty in their judgments. Parents would benefit from information about the developmental aspects of pain and should be included as active partners in their children's pain assessment and management.

Inflammation of the temporomandibular joint (TMJ) induced by rheumatoid arthritis (RA) have resulted in persistent pain and caused distress to many patients. Considering that not all patients respond to traditional drugs therapy to RA and it has demonstrated that 15-deoxy-Δ12,14-prostaglandin J2 (15d-PGJ2) into TMJ has a potential peripheral antinociceptive effect, the aim of this study was to evaluate the peripheral effect of 15d-PGJ2 in RA-induced TMJ inflammatory hypernociception. ⋯ In the present study, we demonstrated that 15d-PGJ2 was able to reduce the RA-induced TMJ inflammatory hypernociception by an indirect mechanism. This antinociceptive effect is in part due to decrease of TNF-α, IL-1β and KC levels and PKA/PKCε expression in the TMJ.
