Randomized Controlled Trial Comparative Study
[Desire for early retirement and therapy of chronic back pain: relevance of social medical variables for outpatient psychotherapeutic treatment].
This study investigated the influence of patients' desire for early retirement on the success of an outpatient cognitive behavioural treatment (CBT) in patients with chronic back pain. Previous studies have shown that the desire for early retirement and social compensation had a negative influence on therapy outcome, e.g. pain intensity and pain disability. This study was conducted to reassess whether these results can be replicated in an outpatient CBT setting. ⋯ CBT in an outpatient setting seems to be an effective treatment for patients with chronic back pain and even patients with a desire for early retirement benefit from treatment.

Randomized Controlled Trial
[Modulation of cortical pain processing by cyclooxygenase inhibition: a functional MRI study].
Little is known about changes in brain activity with pharmacological modulation of hyperalgesia. Therefore, we sought to investigate the cerebral processing of hyperalgesia and acute pain using functional magnetic resonance imaging (fMRI) and pharmacological modulation with cyclooxygenase (COX) inhibitors. ⋯ This study provides new evidence for the involvement of COX inhibitors in modulating the cerebral activity associated with acute pain and hyperalgesia. Our results hint at a differential modulation of brain areas under either analgesia or antihyperalgesia.

Older patients, particularly those with multimorbidity, complain about many symptoms which also occur under analgesics (especially with opioids). The goals of the study were to quantify symptoms and discuss the relationships to analgesics, pain, multimorbidity, function, age and gender. ⋯ Our results underline the difficult interpretation of symptoms as a side-effect of analgesic treatment in older patients. Pain and gender differences have to be considered. The recommendation to carefully record symptoms before analgesic treatment is supported by our results.

Criterion-related validity of the Mainz Pain Staging System (MPSS) was examined. ⋯ The results support criterion validity of the MPSS, however, they also corroborate the concept that identification of medium and high grade pain by the MPSS has to be followed by a psychological diagnostic assessment. By this stepwise diagnostic process, therapy aims and treatment regimens can be designed more adequately.
