Review Meta Analysis
[Placebo responders in randomized controlled drug trials of fibromyalgia syndrome : Systematic review and meta-analysis].
The superiority of true drug treatment over placebo in reducing symptoms of fibromyalgia syndrome (FMS) is small. Drug placebo treatment of functional somatic syndromes (FSS) such as FMS has been discussed. We determined the magnitude of placebo responders in drug trials with FMS patients to substantiate further research on placebo treatment of FSS. ⋯ The magnitude of responders to placebo in drug trials of FMS is substantial. The efficacy, safety, and costs of drugs recommended for FMS therapy and open-label placebo should be compared in large multinational trials sponsored by public institutions. The English full-text version of this article is available at SpringerLink (under "Supplemental").

Nondermatomal somatosensory deficits (NDSDs) are frequently found in chronic pain patients and allude to pain sensitization and pain centralization. In the clinical examination NDSDs are as a rule accompanied by hyposensitivity to touch and heat perception often with a quadrantal or hemibody distribution. ⋯ Most patients with chronic pain disorders as well as those with NDSD often report an antecedent period of high psychobiological stress. The data from functional imaging reveal a complex pattern of a central nervous dysregulation.

Comparative Study
[Physicians' knowledge on cancer pain therapy : Comparison of palliative care and prehospital emergency physicians in training].
Palliative care needs a high level of expertise. In particular, there are some potential difficulties in the treatment of patients with the symptom cancer pain (for example lack of education). In Germany, various physicians are involved in cancer pain treatment but in general palliative care patients are treated by a physician who is educated in palliative medicine. In special circumstances prehospital emergency physicians and other physicians are involved in therapy decisions in palliative care patients as well. The authors surveyed different groups of physicians in Germany about their specific knowledge of cancer pain management. ⋯ The results of this study verified that the highest knowledge scores were achieved by PPs and overall, the knowledge scores showed an improvement in comparison to previous investigations. In recent years there seems to have been an improvement in education on pain treatment,for example during medical school. Whether this also leads to an improvement of patient care and the relevance of these data for the clinical practice needs to be investigated in further studies.

Palliative care in nursing homes has become an increasing focal point of healthcare in Germany and the evaluation of the specific quality of palliative care in this setting is under discussion. The assessment of quantitative data has the advantage of allowing pre-post comparisons of different interventions and implementation procedures and can therefore be used for evaluation of effectiveness. However, no assessment tool in German is available yet. Recent research on the assessment of healthcare professionals' knowledge indicated that knowing about technical and psychosocial aspects of palliative care is an easily measurable index for the quality of care. In consequence this index will be used as the core of the test instrument. The specific self-efficacy related to palliative care should be additionally included. ⋯ The BPW is the first standardized test instrument for palliative care in the German language. In comparison to the other tests it includes items from the psychosocial domain without demonstrating a ceiling effect for these items. Content and criterion validity were good. Additional tests with larger samples and with other groups of nurses working in other settings would be needed to improve the data on reliability and to extend the validation to other settings.
