Abnormalities of the hallux skin and nail in the course of very rare arteriovenous malformation.

Arteriovenous malformations (AVMs) are usually found in the pelvic area and the brain. These vascular anomalies are rarely reported in the toes. AVMs in the toes may be asymptomatic, but can also cause atypical symptoms.

The influences of selected clotting and fibrinolysis factors on survival of patients with kidney tumors - a prospective study.

Introduction: Multiple studies suggest that cancer leads to activation of clotting and fibrinolysis pathways, elevating the risk of thromboembolic events. Kidney cancer is often complicated by clotting disorders. In this study, we hypothesized that preoperative clotting and fibrinolysis parameters are altered in healthy volunteers and kidney tumor patients.

Von Willebrand Factor and ADAMTS13 as Predictors of Adverse Outcomes in Patients With Nonvalvular Atrial Fibrillation.

Background: Von Willebrand factor (VWF) elevation correlates with the left atrial blood stasis in nonvalvular atrial fibrillation (NVAF). However, the long-term impact of elevated VWF in patients with NVAF is not well established.

Methods: To assess the impact of VWF and a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 (ADAMTS13) in conjunction with echocardiographic measures of left atrium blood stasis on clinical outcomes, 414 NVAF prospectively recruited (October 4, 2007, to April 27, 2009) patients were followed for 3 years.

Association between P-selectin levels and left atrial blood stasis in patients with nonvalvular atrial fibrillation.

Background: P-selectin - a biomarker of platelet and endothelial cell activation is elevated in patients with non-valvular atrial fibrillation (NVAF). However, the association between sP-selectin level and thromboembolic complications in NVAF patients remains controversial. We tested the hypothesis that plasma soluble P-selectin (sPSL) level correlates with the measures of left atrial blood stasis in NVAF.

Analysis of peripheral nerve and autonomic nervous system function and the stage of microangiopathy in patients with secondary Raynaud's phenomenon in the course of connective tissue diseases.

Background: The pathogenesis of secondary Raynaud's phenomenon (SRP) associated with connective tissue diseases (CTD) is not entirely understood. Nervous system dysfunction and microangiopathy are considered to be causes of this pathology.

Objectives: Peripheral and autonomic nervous system function, the stage of microangiopathy, and the relationships between these in patients with SRP were analyzed.
