Background Neuropathic pain remains a significant challenge with unsatisfactory therapeutic options. Its pathogenesis may involve the neuropathic triad of neuronal, glial and immune cells. Communication between these cells is possibly perpetuated by mitogen-activated protein kinase (MAPK)-signaling. ⋯ Conclusions/implications EGFR-inhibition resulted in dramatic relief of neuropathic pain. A plausible biological explanation involves the interruption of MAPK-signaling. The role of EGFR-inhibition as a target for the treatment of neuropathic pain appears promising and warrants investigation.

Background and purpose The UV-B model is an established pain model of different types of hyperalgesia in animal and human pain research. Beside the skin region of the sunburn in human volunteers pinprick hyperalgesia has been described in a large zone of non-inflamed skin adjacent to the sunburn. However, there are opposing results on the existence of pinprick hyperalgesia and most notably a controversial discussion is still on-going whether this mechanical hyperalgesia in the undamaged tissue adjacent to and at some distance from the site of inflammation is of peripheral or central origin. ⋯ Furthermore, these findings are in line with other pain models demonstrating comparable central hypersensitivity around the site of injury. Implications As for other pain models this finding provides further evidence that the UV-B model offers secondary mechanical hyperalgesia in addition to its known primary hyperalgesia. Consequently, this is a further validation for the utilisation of the UV-B model in human pain research.

Background and aim Physicians' attitudes predict clinical decision making and treatment choices, but the association between attitudes and behaviour is complex. Treatment guidelines for non-specific low back pain (LBP) include recommendations of early assessment of psychosocial risk factors forchronic pain, patient education and reassurance. Implication of these principles is demanding, and many patients are not referred for appropriate treatments due to a lack of systematic screening of psychosocial risk factors for chronic pain. ⋯ However on a process level, evaluation and treatment of LBP featured biomechanical principles. LBP guidelines were only partially followed. Implications Clinical behaviour of physicians in the treatment of LBP is complex and only partly explained by attitudes.
