The coagulation cascade is controlled by several anticoagulant safeguards that avoid excessive clot formation. Disorders of these anticoagulant mechanisms are an important health problem, as they lead to increased risk of thromboembolism. Protein C deficiency is probably the most extensively studied abnormality in natural anticoagulants. Under the auspices of the Subcommittee on Plasma Coagulat...

Background As for other pathologies, the pathogenesis of venous thrombo-embolism (VTE) is multifactorial. A comprehensive understanding of the pathogenesis of venous thrombosis is essential for identifying patients at increased risk as in elderly patients with congestive heart failure (CHD) and with presence of chronic venous insufficiency (IVC). Eberhard Mammen postulated immobility as the lea...

BACKGROUND Migraine is a complex disease whose physiopathological mechanisms are still not completely revealed. FINDINGS We describe an unusual case, not yet described in literature, of a patient who reported migraine remission, but still presented aura attacks, since starting a therapy with Warfarin. CONCLUSIONS This case report brings out new questions on the role of the coagulation, espe...

The authors conducted an investigation focusing mainly on the activities of the inhibitory factors of the coagulation and fibrinolysis processes in 35 normal adults and 72 liver cirrhosis and/or hepatoma patients. The activities of antithrombin III, protein C, and alpha 2-plasmin inhibitor were reduced to less than 50% in patients with decreased hepatic synthetic function while lupus anticoagul...

A patient was referred for investigation of heavy bleeding after surgery. He showed several features of hypothyroidism but no goitre. Primary autoimmune hypothyroidism was confirmed by the finding of a low serum thyroxine concentration and a high thyrotropin concentration. Factor VIII concentration was low, and a mild coagulation inhibitor was found. The patient was treated with thyroxine and r...

Selenium plays an important role in biological system due to its incorporation in glutathione peroxidases and thioredoxin reductase as prosthetic group, the pharmacological studies of synthetic organoseleno-compounds revealed these molecules to be used as antioxidants, enzyme inhibitors, neuroprotectors, antitumor, anti-infectious agents, cytokine inducers and immuno-modulators. The present stu...

Modern orthopedic surgery can improve the musculoskeletal problems of people with hemophilia. The most commonly affected joints are the knees, the ankles and the elbows. The most common orthopedic procedures that PWH undergo are the following: RS, arthroscopic synovectomy, arthroscopic joint debridement, ankle arthrodesis, total joint arthroplasty and removal of pseudotumors. Every surgical pro...
