Aorto-Right Atrial and Aorto-Right Ventricular Fistulas as a Complication of Subacute Infective Endocarditis.

Unlabelled: Aorto-atrial fistula (AAF) and aorto-ventricular fistula (AVF) are a rare, but potentially life-threatening condition, where an anomalous connection forms between the aortic structures and the cardiac atria or ventricles. The exact incidence of this condition is unknown, as are the major precipitating factors and best treatment options. It may be congenital, secondary to conditions such as aortic dissection, infective endocarditis, or valve replacement, or iatrogenic in nature.

Mental Manifestations and Biomarkers of Alcohol Consumption.

The purpose of this study is to examine healthcare usage, morbidities, and alcohol consumption monitoring in patients before a diagnosis of mental manifestations to assist in the early identification of individuals at risk. Biological markers of alcoholism are separated into two groups: those biological variables that highlight with great confidence and validate the presence of a predisposition to alcoholism, also called trait markers, or those that highlight alcohol consumption, called markers of alcoholism ("status markers"). Biomarkers are the true "gold standard" for the diagnosis of alcoholism.
