BACKGROUND AND PURPOSE Cerebral venous thrombosis (CVT) is nowadays considered a disease with a good outcome in most cases, but in the past, these patients were thought to have a grave prognosis. We systematically studied the apparent decline in mortality of patients with CVT over time. METHODS A systematic review of the literature (MEDLINE and EMBASE) was performed. Studies with ≥40 patients...

BACKGROUND Cerebral venous thrombosis is a relatively uncommon neurologic disorder that is potentially reversible with prompt diagnosis and appropriate medical care. The pathogenesis is multifactorial and the disease may occur at any age. CVT is often associated with nonspecific symptoms. Radiologists play a crucial role in patient care by providing early diagnosis through interpretation of ima...

A recently developed centroidal Voronoi tessellation (CVT) sampling method is investigated here to assess its suitability for use in statistical sampling applications. CVT efficiently generates a highly uniform distribution of sample points over arbitrarily shaped Mdimensional parameter spaces. On several 2-D test problems CVT has recently been found to provide exceedingly effective and efficie...

Cerebral venous thrombosis (CVT) is a rare origin of stroke, the clinical presentation and etiologies vary. The prognosis is shown to be better compared to arterial thrombosis. Magnetic Resonance Imaging (MRI) and MR Venograpgy (MRV) are currently important tools for the diagnostic. We studied 30 cases of CVT diagnosed in the department of neurology of the University Hospital of Fez (Morocco). ...

BACKGROUND Anticoagulation therapy is a routine treatment in patients with hemorrhagic cerebral venous thrombosis (CVT). However, fear of hemorrhagic complications and deterioration course following anticoagulation often disturbs the responsible physician. METHODS This was a Prospective observational study on consecutive CVT patients with hemorrhagic venous infarction or subarachnoid hemorrha...

R esults from clinical studies and advances in radiological diagnosis during the past 20 years have significantly altered the management of patients with cerebral venous thrombosis (CVT), with resultant improvement in overall prognosis and decreased mortality. Although the efficacy of anticoagulation in CVT has not been unequivocally proven, it is widely used as the mainstay therapy. There is a...

OBJECTIVE To determine the diagnostic performance and cost-effectiveness of colour vision testing (CVT) to identify and monitor the progression of diabetic retinopathy (DR). DATA SOURCES Major electronic databases including MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature, and Cochrane Database of Systematic Reviews were searched from inception to September 2008. RE...

Proper orthogonal decompositions (POD) have been used to systematically extract the most energetic modes while centroidal Voronoi tessellations (CVT) have been used to systematically extract best representatives. We combine the ideas of CVT and POD into a hybrid method for model reduction. The optimality of such an approach and various practical implementation strategies are discussed.

The diagnostic criteria for TA are mainly clinical; nevertheless, laboratory analysis frequently reveals increased ESR and CRP. Although they are not gold standard, CTA and MRI are useful keys to diagnosis1,4. During the acute phase, inflammatory infiltration affects all layers of the arterial wall, whereas at the chronic phase fibrous tissue replaces the damaged layers and arterial stenosis ma...

Macroautophagy is a catabolic membrane trafficking phenomenon that is observed in all eukaryotic cells in response to various stimuli, such as nitrogen starvation and challenge with specific hormones. In the yeast Saccharomyces cerevisiae, the induction of autophagy involves a direct signal transduction mechanism that affects membrane dynamics. In this system, the induction process modifies a c...
