The medical records of nine patients (five female and four male, mean age 58 +/- 5 years) presenting with a carotid chemodectoma between 1983 and 1995 were reviewed. In two cases (22%) the diagnostic was not suspected at the time of initial presentation. The most common complaint was a swelling in the anterolateral region of the neck. One patient (11%)(More)
Revascularization of a limb after a severe and prolonged period of ischemia may be associated with high rates of mortality and amputation, because of the development of a postrevascularization syndrome, regardless the cause of occlusion (ischemia, trauma, iatrogenic) or the methods used to achieve reperfusion (fibrinolysis, surgery, resuscitative therapy).(More)
BACKGROUND Oxidative stress is associated with the development of several disorders including cardiovascular disease and cancer. Among conditions known to influence oxidative stress, the use of oral contraception (OC) in women has been a matter of ongoing discussion. METHODS A total of 897 eligible and healthy volunteers were recruited from among the(More)
Antioxidant status and titers of autoantibodies against oxidized low-density lipoproteins (ox-LDL-Ab) were investigated in top soccer (S; n = 21, age 24.6 +/- 4.3 years) and basketball (B; n 3,000 mIU/ml) in ox-LDL-Ab were found in half the players (12S and 4B) with a maximum reaching 6000 mIU/ml (normal range: 200-600 mIU/ml), showing an in vivo LDL(More)
BACKGROUND Cardiopulmonary bypass (CPB) initiates a whole-body inflammatory response where complement and neutrophil activation and cytokine release play an important role. This prospective trial examined the effects of both heparin-coated circuits and aprotinin on the inflammatory processes during CPB, with respect to cytokine release and neutrophil(More)
BACKGROUND Functional imaging using positron emission tomography (PET) showed increased metabolic activities in the aneurysm wall prior to rupture, whereas separate studies using finite element analysis techniques found the presence of high wall stresses in aneurysms that subsequently ruptured. This case series aimed to evaluate the association between wall(More)
Intraoperative blood salvage devices allowing a reinfusion of red blood cells (RBCs) after processing of shed blood and stagnant blood in the mediastinal cavity are more and more used to reduce homologous blood requirements in cardiac surgery with cardiopulmonary bypass (CPB). As the proinflammatory activity of the shed blood also contributes to morbidity(More)
Chronic rupture of abdominal aortic aneurysm (AAA) resulting in unusual clinical manifestations can occur if the resistance of structures surrounding the aorta is sufficient to contain hemorrhage. In this report, we describe five cases of chronic ruptured AAA in which the presenting feature was crural neuropathy. All patients were male with a mean age of 74(More)
