Hintergrund. Rotaviren (RV) sind häufige Erreger von Gastroenteritiden bei Kindern weltweit. In Deutschland liegen im Vergleich zu anderen Ländern nur wenige epidemiologische Daten zur Inzidenz von RV-Infektionen vor. Aus diesem Grund wurde eine prospektive Multizenterstudie zur Erfassung der Morbidität und Hospitalisierungshäufigkeit von RV-Infektionen in(More)
Recent meta-analyses find various magnitudes of placebo analgesia effects in placebo mechanism trials versus placebo control trials, which have led to debate. To further investigate the magnitude of placebo analgesia in placebo mechanism trials the databases "PubMed", "PsycINFO" and "Web of Science" (2002-2007) were searched with the term "placebo(More)
Bei der Versorgung polytraumatisierter Patienten spielt der Faktor Zeit eine entscheidende Rolle, und Zeitverzögerungen verschlechtern die Prognose. Aktuelle Studien zeigen darüber hinaus, dass Traumapatienten von der primären Zuführung in ein Traumazentrum profitieren. In Deutschland kommen daher bodengebundene und luftgestützte Notarztsysteme, allein oder(More)
Several studies have shown that placebo analgesia effects can be obtained in healthy volunteers, as well as patients suffering from acute postoperative pain and chronic pain conditions such as irritable bowel syndrome. However, it is unknown whether placebo analgesia effects can be elicited in chronic pain conditions with a known pathophysiology such as a(More)
The investigation of nocebo effects is evolving, and a few literature reviews have emerged, although so far without quantifying such effects. This meta-analysis investigated nocebo effects in pain. We searched the databases PubMed, EMBASE, Scopus, and the Cochrane Controlled Trial Register with the term "nocebo." Only studies that investigated nocebo(More)
Research on placebo analgesia and nocebo hyperalgesia has primarily included healthy subjects or acute pain patients, and it is unknown whether these effects can be obtained in ongoing pain in patients with chronic pain caused by an identifiable nerve injury. Eighteen patients with postthoracotomy neuropathic pain were exposed to placebo and nocebo(More)
BACKGROUND It is an inherent assumption in randomised controlled trials that the drug effect can be estimated by subtracting the response during placebo from the response during active drug treatment. OBJECTIVE To test the assumption of additivity. The primary hypothesis was that the total treatment effect is smaller than the sum of the drug effect and(More)
Placebo analgesic effects appear to be related to patients' perception of the therapeutic intervention. In this paper, we review quantitative findings of how the relationship with the physician and the verbal suggestions given for relief may influence patients' perception of a treatment and how patients' expectations and emotional feelings may affect(More)
The magnitude of placebo analgesia effect appears to be large in chronic pain patients experiencing hyperalgesic states. So far, placebo effects have primarily been investigated in idiopathic pain conditions, such as irritable bowel pain syndrome, but more recently they have also been investigated in neuropathic pain patients, in which the underlying nerve(More)
OBJECTIVE Placebo effects are usually calculated as the difference between placebo treatments and no treatments. Recently, placebo-like effects have been investigated using open and hidden administrations of active treatments. The aim of the study was to directly compare the two types of placebo effects and examine how they are influenced by personality(More)
