"Recurrent" posterior reversible encephalopathy syndrome: report of 3 cases--PRES can strike twice!

In a retrospective review, 3 (3.8%) of 78 patients developed recurrent posterior reversible encephalopathy syndrome. Underlying clinical conditions included sickle cell disease, antibody-positive autoimmune disease, and allogeneic bone marrow transplantation.

Cationic lipid-mediated transfection of bovine aortic endothelial cells inhibits their attachment.

The need for a small-diameter vascular graft for coronary artery and peripheral vascular replacement is great and is projected to increase as the population ages. Synthetic small-diameter vascular grafts fail because of acute thrombosis or chronic intimal hyperplasia leading to restenosis. Endothelial cell seeding has been attempted with limited success in the femoral artery by Zilla and others.
