Inherited risk factors for venous thrombosis.
Venous thrombosis occurs as a consequence of genetic and environmental risk factors. Since the discovery of factor V Leiden, the most common genetic risk factor, there has been intense interest in clarifying the roles of genes and the environment with thrombosis risk. The translation of this risk information to clinical practice is a challenging one in the setting of a rapidly expanding knowled...
متن کاملComputer-aided diagnostic detection system of venous beading in retinal images
Chein-I Chang, MEMBER SPIE University of Maryland—Baltimore County Department of Computer Science and Electrical Engineering Baltimore, Maryland 21250 E-mail: [email protected] Abstract. The detection of venous beading in retinal images provides an early sign of diabetic retinopathy and plays an important role as a preprocessing step in diagnosing ocular diseases. We present a computer-aided diag...
متن کاملBiomechanics of stretch-induced beading.
To account for the beading of myelinated fibers, and axons of unmyelinated nerve fibers as well of neurites of cultured dorsal root ganglia caused by mild stretching, a model is presented. In this model, membrane tension and hydrostatic pressure are the basic factors responsible for axonal constriction, which causes the movement of axonal fluid from the constricted regions into the adjoining ax...
متن کاملInherited prothrombotic risk factors and cerebral venous thrombosis.
Fifteen patients with cerebral venous thrombosis were ascertained retrospectively. Their case notes were reviewed, and stored or new blood was assayed for factor V Leiden (FVL) mutation, prothrombin gene mutation 20201A, and 5,10 methylene tetrahydrofolate reductase (MTHFR) C677T mutation. A clinical risk factor was identified in 13 patients--the oral contraceptive pill (5), puerperium (1), HRT...

effect of the WBC count. In both cases, complications occurred with the development of marked WBC count elevations a few days after initiating the cytokine treatment in clinically well individuals. These cases suggest that an acute elevation in the polymorphonuclear leukocyte count can promote acute sickle cell complications. Alternatively or additionally, G-CSF–induced changes in granulocyte f...
