Evaluation of a hypertension-based patient education program in a stroke center.

Background The benefits of educational programs are recognized in chronic diseases. An education program was designed in our hospital, for hypertensive patients after an acute episode of stroke to prevent stroke recurrence. Objective Evaluate the effects of such program on patient knowledge and blood pressure management.

Detection of occult atrial fibrillation by pacemaker interrogation in cryptogenic stroke.

Purpose: Atrial fibrillation (AF) is a major cause of ischemic strokes, and it is assumed that occult intermittent episodes of AF are responsible for some of the seemingly cryptogenic strokes. Cardiac pacemakers feature rhythm diagnostic capabilities and data storage. We investigated whether pacemaker memory interrogation led to identification of undetected AF episodes prior to cryptogenic strokes.

[Insulin in the treatment of ischemic stroke].

Hyperglycemia is correlated with poor prognosis in ischemic strokes and also increases the risk of hemorrhagic transformation after thrombolysis. The toxicity of hyperglycemia, already well established in animals, is beginning to be clear for humans. On the other hand, the beneficial effect of insulin remains controversial in animals and has never been demonstrated in humans.

A cognitive characterization of dyscalculia in Turner syndrome.

Current theories of number processing postulate that the human abilities for arithmetic are based on cerebral circuits that are partially laid down under genetic control and later modified by schooling and education. This view predicts the existence of genetic diseases that interfere specifically with components of the number system. Here, we investigate whether Turner syndrome (TS) corresponds to this definition.

Functional and structural alterations of the intraparietal sulcus in a developmental dyscalculia of genetic origin.

Cognitive theories of numerical representation suggest that understanding of numerical quantities is driven by a magnitude representation associated with the intraparietal sulcus and possibly under genetic control. The aim of this study was to investigate, using fMRI and structural imaging, the interaction between the abnormal development of numerical representation in an X-linked condition, Turner syndrome (TS), and the development of the intraparietal sulcus. fMRI during exact and approximate calculation in TS showed an abnormal modulation of intraparietal activations as a function of number size.
