The aim of this study was to examine the associations between coping and adjustment to chronic pain in a sample of patients from Portugal and to discuss the findings with respect to published findings from two studies using patients from the United States. ⋯ The results support the reliability and validity of the translated Coping Strategies Questionnaire and Chronic Pain Coping Inventory and also indicate a number of similarities, but also some interesting differences, in the findings from the Portuguese vs US samples, suggesting that there may be cultural differences in how people cope with pain.

The aim of this study was to validate the Pain Impact Questionnaire (PIQ-6) for Portuguese adults with a chronic pain condition. ⋯ The PIQ-6 proved to be equivalent in both cultures (American/Portuguese), and is useful, reliable, and valid for use in Portugal.

The physiological sensation of pain and rapid response to stimuli serve as an adaptive way to avoid harmful situations. Our purpose was to investigate why this protection disappears or almost disappears for patients with congenital indifference to pain (CIP). ⋯ We speculate that the mutations may be the cause of partial deletion of pain perceptionin in our probands, and the novel polymorphism V1104L may have a predictive role in the pain sensation of healthy individuals.

To compare differences in the prevalence and the anatomical localization of the referred pain areas of active trigger points (TrPs) in head and neck musculature between adults and children with chronic tension-type headache (CTTH). ⋯ This study showed that the referred pain elicited from active TrPs shared similar pain patterns as spontaneous CTTH in adults and children. Differences in TrP prevalence and location of the referred pain areas can be observed between adults and children with CTTH.
