The literature on chronic diseases recognizes the role of illness cognition as a mediator between stress and illness. Few conceptualizations and instruments, however, give an indication of both unfavorable and favorable ways of adjusting to an uncontrollable long-term stressor, such as a chronic disease. The authors propose 3 generic illness cognitions that(More)
Patients' expectations are important predictors of the outcome of analgesic treatments, as demonstrated predominantly in research on placebo effects. Three commonly investigated interventions that have been found to induce expectations (verbal suggestion, conditioning, and mental imagery) entail promising, brief, and easy-to-implement adjunctive procedures(More)
BACKGROUND Physicians are frequently confronted with patients reporting severe itch and pain. Particularly in patients suffering from persistent itch and pain, central and peripheral sensitization processes are assumed to be involved in the long-term maintenance and aggravation of the symptoms. The present study explores generalized and symptom-specific(More)
Patients frequently report high levels of physical symptoms, such as itch and pain, which do not completely correspond to pathophysiological findings, possibly indication heightened sensitivity to physical symptoms. Sensitivity to itch and pain is thought to be affected by processes such as attentional focus on bodily sensations. We investigated the role of(More)
OBJECTIVE Stress-vulnerability factors were studied for their ability to predict long-term disease activity in early rheumatoid arthritis. METHODS In a prospective study involving 78 recently diagnosed rheumatoid arthritis (RA) patients, the role of personality characteristics (neuroticism, extraversion), physical and psychological stressors (chronic,(More)
Recent developments in chronic pain research suggest that effectiveness of cognitive-behavioral therapy (CBT) may be optimized when applying early, customized treatments to patients at risk. For this purpose, a randomized, controlled trial with tailor-made treatment modules was conducted among patients with relatively early rheumatoid arthritis (RA disease(More)
Pain can be endogenously modulated by heterotopic noxious conditioning stimulation (HNCS) through a mechanism which is known as diffuse noxious inhibitory control (DNIC). Since DNIC can be impaired in patients suffering from chronic pain, a comparable impaired itch inhibition may exist in patients suffering from chronic itch. The aim of the present study(More)
It is well-known that cognitive, behavioral, and physiological reactivity to pain, such as catastrophizing, avoidance of activity, and increased physiological responses, can unfavorably affect long-term outcomes in patients with chronic pain. In line with similarities between the psychophysiology of pain and itching, corresponding mechanisms may be relevant(More)
BACKGROUND Previous studies have extensively documented antimicrobial and chemotactic activities of beta-defensins. Human beta-defensin-2 (hBD-2) is strongly expressed in lesional psoriatic epidermis, and recently we have shown that high beta-defensin genomic copy number is associated with psoriasis susceptibility. It is not known, however, if biologically(More)
Cognitive-behavioral factors are considered important in the development of chronic disability and pain in patients with low back pain. In a prospective cohort study of 277 patients undergoing surgery for lumbosacral radicular syndrome, the predictive value of preoperatively measured cognitive-behavioral factors (fear of movement/(re)injury, passive pain(More)
