Anomalous origin of the left coronary artery from the pulmonary artery is a rare congenital abnormality with a poor prognosis in the newborn. Adult forms are, therefore, very rare, presenting with angina, cardiac failure or sudden death. The authors report the case of a 41 year old woman who was asymptomatic until admitted as an emergency after ventricular fibrillation. Coronary angiography established the diagnosis. Despite the absence of reversible ischaemia on exercise myocardial scintigraphy, the patient underwent coronary bypass surgery of the left anterior descending artery with a pediculated internal mammary artery graft and closure of the left coronary ostium on the pulmonary artery. The echocardiographic abnormalities regressed within a few weeks. An automatic defibrillator was not implanted. The physiopathology of this rare cardiac lesion, the mechanisms of sudden death and the different techniques of surgical repair are discussed. 相似文献

Recent research on the pathogenesis of spondyloarthritis and related immune-mediated diseases associated with human leukocyte antigen class I molecule B27 (HLA-B27) has led to significant progress in terms of management and prognosis, with multiple treatments being constantly evaluated and implemented. Correlations between the genetic background of spondyloarthritis and inflammatory bowel diseases and the inflammatory processes involving gut microbiota have been established. This knowledge has allowed progress in pharmacological therapy. The role of diet in the pathogenesis and treatment of diseases pertaining to the HLA-B27 spectrum is of great significance, considering possible future applications in individualized medicine. Diet impacts the composition of gut microbiota, representing a substrate for the synthesis of metabolites affecting the mucosal immune system. Certain pro-inflammatory mediators, such as emulsifiers and microparticles, induce a more profound cytokine response, promoting inflammation. Numerous diets, including the low-starch diet, the Mediterranean diet, diets with low contents of fermentable oligosaccharides, disaccharides, monosaccharides and polyols (low-FODMAP diets), gluten-free diets and fasting, have been analysed and correlated with patients’ symptomatology and dietary adherence. The aim of this review is to provide an extensive perspective on the diets available to patients with spondyloarthritis and related immune-mediated disorders. 相似文献

Aim of our study was to investigate effects of eptifibatide and anticoagulants on platelet aggregation and thrombin generation under low and high coagulant challenge in tissue factor-activated platelet rich plasma using a model allowing simultaneous determination of the time course of platelet aggregation and thrombin generation. Eptifibatide exerted a dose-dependent anti-aggregating effect under both high and significantly stronger under low coagulant challenge. Combination of eptifibatide and anticoagulants resulted in significant additive prolongation of the lag phase until the onset of platelet aggregation, more pronounced under low coagulant challenge. Under high, but not under low coagulant challenge combination of eptifibatide and anticoagulants had a significant synergistic inhibitory effect on platelet aggregation. Under low coagulant challenge combination of eptifibatide with LMWH, but not with UH, or rH, resulted in significantly reduced thrombin potential, F 1+2 generation, and FXa formation compared to measurements in the absence of eptifibatide. We demonstrate a synergistic effect of eptifibatide and anticoagulants on platelet aggregation inhibition and an additional inhibitory effect of LMWH and eptifibatide on thrombin generation. Our results support the notion that combination of eptifibatide and anticoagulants might be beneficial in atherosclerotic disease to palliate the thrombogenic potency of ruptured atherosclerotic plaques. 相似文献

A two year old boy was seen in the orthopedic clinics because of typical symptoms of Legg-Perthes disease, a scintigraphy with Technetium99m showed a distinct deficiency of nuclear activity in the femoral head which is characteristic of the early stage of Legg-Perthes disease. A routine blood count lead to the diagnosis of acute lymphoblastic leukemia. The boy was treated according to the Austrian cooperative leukemia protocol and complete remission was achieved. No orthopedic treatment of the femur head necrosis was done, after eight weeks of treatment with multiagent chemotherapy the boy started to walk again and subsequently became free of all symptoms of Legg-Perthes disease. A scintigraphy done eight weeks after the initial scintigraphy showed that the deficiency of radionuclear activity of the femoral head was nearly vanished. This case illustrates the variability of bone involvement in acute lymphoblastic leukemia, which often is the most prominent symptom at an early stage of the disease. 相似文献

Abstract. To study the dissociation of the two moieties of the factor-VIII complex during clotting, plasma, concentrate and serum were chromatographed on 4% agarose. In plasma and concentrate factor-VIII coagulant activity (VIII C), factor-VIII coagulant antigen (VIII C:Ag), and factor-VIII-related antigen (VIII R:Ag) eluted together in the void volume, but some VIII C: Ag eluted after the void volume. The amount of VIII C:Ag eluting after the void volume was made smaller by adding proteinase inhibitors. In serum nearly all VIII C:Ag eluted after the void volume.
From factor-VIII complex immunoadsorbed by means of an antibody against VIII R:Ag no VIII C:Ag was dissociated by thrombin or by thrombin and physiologic CaCl2 concentrations. Radiolabelled human thrombin did not bind to the VIII C:Ag of immunoadsorbed factor-VIII complex. VIII C:Ag displaying VIII C was dissociated from immunoadsorbed factor-VIII complex by human brain thromboplastin or by phosphatidyl-serine.
Our results suggest that VIII C:Ag and VIII R:Ag dissociate during clotting. This dissociation seems not to be mediated by thrombin, but may be mediated by phospholipids. 相似文献
