Mechanics of early ventricular impairment in systemic sclerosis and the effects of peripheral arterial haemodynamics.

Objectives: Multiple mechanisms commonly lead to severe cardiac involvement in systemic sclerosis (SSc), an autoimmune disease characterised by microvascular lesions, systemic inflammation and fibrosis. Herein, we examined the mechanics of right and left ventricles (RV, LV) at the early stage of impairment and tested the hypothesis that peripheral vasculopathy influences the possible early compromise of LV.

Methods: Ninety-five SSc patients free of any cardiovascular disease or related symptoms (88% women, 53±14 years) and 54 subjects matched for age, gender, arterial hypertension, dyslipidaemia, and diabetes mellitus underwent echocardiography, including multilayer speckle-tracking, and tonometry-based pulse wave analysis of the peripheral arteries; 66 SSc patients were prospectively assessed after 32±7 months.

The Medical Vestment and Surgical Instruments of Saint Cosmas and Damian on Sinai Icons From the Seventh to the Eighteenth Century.

The iconography of the doctor saints Cosmas and Damian and the artistic representations of their miracles are important sources for the history of medicine. Within the sphere of physician-saints, Cosmas and Damian have the greatest number of iconographic depictions in Byzantine and Post-Byzantine art. In most of their representations, they wear long robes as a sort of professional mantles and carry surgical instruments and boxes indicating their status as doctors.
