BACKGROUND Increasing the cross-sectional area (CSA) of the right internal jugular vein facilitates cannulation and decreases complications. Maneuvers such as the Trendelenburg tilt position and ventilation with a positive end-expiratory pressure (PEEP) may increase the CSA of the right internal jugular vein. We determined the changes in the CSA in response(More)
Over the years, many have viewed Fibromyalgia syndrome (FMS) as a so-called "functional disorder" and patients have experienced a concomitant lack of interest and legitimacy from the medical profession. The symptoms have not been explained by peripheral mechanisms alone nor by specific central nervous system mechanisms. In this study, we objectively(More)
OBJECTIVE There is vast evidence to support the presence of brain aberrations in patients with fibromyalgia (FM), and it is possible that central plasticity is critical for the transition from acute to chronic pain. The aim of the present study was to investigate the relationship between brain structure and function in patients with FM. METHODS Functional(More)
Die Messung der Druckschmerzschwelle und der überschwelligen Druckschmerzempfindlichkeit mit einem neu entwickelten computergesteuertem Algometer wurde in einer Pilotuntersuchung mit etablierten Methoden verglichen. An 37 Gesunden und 64 Probanden mit chronischen Schmerzen wurden die Druckschmerzschwellen mit einem elektronischen Algometer (Somedic) und dem(More)
UNLABELLED The prognostic value of the four most common histopathological classification systems in gastrointestinal stromal tumors (GISTs) was evaluated retrospectively. PATIENTS AND METHODS Twenty-five consecutive patients with resected GIST and a follow-up of five years or more for surviving patients were included in this analysis. All the tumors were(More)
OBJECTIVE Mood disturbance is common among patients with fibromyalgia (FM), but the influence of psychological symptoms on pain processing in this disorder is unknown. We undertook the present study to investigate the differential effect of depressive symptoms, anxiety, and catastrophizing on 1) pain symptoms and subjective ratings of general health status(More)
BACKGROUND There is evidence for augmented processing of pain and impaired endogenous pain inhibition in Fibromyalgia syndrome (FM). In order to fully understand the mechanisms involved in FM pathology, there is a need for closer investigation of endogenous pain modulation. In the present study, we compared the functional connectivity of the descending pain(More)
BACKGROUND In a pilot study we could show that hydroxyethyl starch (HES) induced a significant reduction of endothelium-dependent relaxation (EDR) and the endothelium-derived hyperpolarizing factor (EDHF). In this follow-up study we investigated whether this effect of HES was dose-dependent and whether it could be replicated with other colloids like dextran(More)
AIM The inflammatory response following tissue injury after major surgery is known to affect endothelial function and vascular reactivity. In this study we evaluated the utility of bedside Digital Thermal Monitoring (DTM) as a surrogate for evaluating vascular function in the postoperative period. METHODS Ischemia-induced reactive hyperemia variables were(More)
BACKGROUND Brachial artery reactivity testing (BART)--a surrogate test of microvascular function--predicts cardiac risk in the nonsurgical population and associates it with adverse outcome after vascular surgery. This pilot study investigated BART-derived variables, including flow-mediated dilation (FMD), in preoperative risk stratification for major(More)
