This study investigated the characteristics of temperature-related evoked neural activities to baseline skin temperatures on target and adjacent sites using contact heat evoked potentials (CHEPs). ⋯ This study using CHEPs shows the importance of baseline and target skin temperatures to investigate the characteristics of temperature-related neural activities. This measure may contribute to understanding of warm-, hot-, and pain-related neural activities in human brains.

Suicidal thinking (ST) is common in people with chronic pain. It is relevant as it can be associated with suicidal attempts, and typically reflects significant suffering. While little is known about the psychological processes that contribute to ST, current psychological models, such as the Psychological Flexibility (PF) model, could help guide further investigation. This study investigates relations between ST and components of PF in chronic pain. ⋯ This study provides evidence that components of psychological flexibility are associated with a reduced frequency of suicidal thinking in people with chronic pain. Treatments targeting psychological flexibility may help mitigate the impact of chronic pain on suicidal thinking.

Effect of patient and nurse ethnicity on emergency department analgesia for children with appendicitis in israeli government hospitals.
Ethnicity is a risk factor for disparate Emergency Department (ED) analgesia. We aimed to explore ethnic variations in the administration of ED analgesia to children with acute appendicitis in Israeli government hospitals. ⋯ Emergency Department analgesia for children with acute appendicitis in Israeli government hospitals is markedly low. Patient-provider ethnic discordance may negatively influence the provision of analgesia. Significant efforts should be undertaken in order to increase analgesia provision rates and reduce social inequality.

Patients with diabetic polyneuropathy commonly suffer from ongoing burning pain and dynamic mechanical allodynia. In this clinical and skin biopsy study, we aimed at assessing how intraepidermal regenerating nerve sprouts are associated with these two types of pain. ⋯ Our skin biopsy study showing that regenerating sprouts, as assessed with GAP43-staining, were strongly associated with ongoing burning pain, improves our knowledge on the mechanisms underlying neuropathic pain in patients with diabetes.

Randomized Controlled Trial
Impact of medial versus lateral knee pain on deep tissue hyperalgesia and muscle strength.
Accumulating evidence indicates that knee pain gives rise to sensory and motor alterations, however, whether different profile of knee pain causes different alterations has not been investigated. The purpose of this experimental study is to clarify characteristics of medial and lateral knee pain and its potential for modulating sensory and motor function in humans. ⋯ The experimental medial knee pain model demonstrated higher pain intensity, more localized pain distribution, widespread deep tissue hyperalgesia and more severe inhibition of muscle strength compared with the lateral knee pain model.
