High prevalence of diabetic retinopathy and lack of association with integrin α2 gene polymorphisms in patients with type 2 diabetes from Northeastern Mexico.

Diabetic retinopathy (DR) is one of the primary causes of blindness in the working age population and is characterized by angiogenesis in the retina. Platelets have been suggested to be involved in the pathogenesis of diabetic microvascular complications. The integrin receptor for collagen/laminin, α2β1, mediates platelet primary adhesion to subendothelial tissues, which is an essential first step in thrombus formation.

[Dilated myocardiopathy complicated with an apical clot secondary to a myocarditis. Report of a case].

Acute myocarditis is a syndrome, until the patient is in heart failure. We report a case illustrating severe systolic dysfunction most probably due to an episode of postviral myocarditis, and the importance of echocardiogram in evaluating possible complications.
