Complete atrioventricular block (CAVB) can be either congenital or acquired in children. Acquired CAVB is occasionally seen in myocarditis patients. To determine the etiology, natural history, and outcome of children with acquired nonsurgical CAVB, we retrospectively reviewed nine children who had suffered CAVB caused by suspected infectious myocarditis.(More)
Pulmonary hemangiomatosis is a rare, usually fatal disorder characterized by diffuse proliferation of blood vessels within the thorax. We describe a 7-year-old boy with cavernous-type pulmonary hemangiomatosis successfully treated with interferon alfa-2a. He presented with respiratory distress and hemoptysis that were alleviated during a 2-year follow-up(More)

In this paper we prove a Carleman estimate for second order elliptic equations with a general anisotropic Lipschitz coefficients having a jump at an interface. Our approach does not rely on the techniques of microlocal analysis. We make use of the elementary method so that we are able to impose almost optimal assumptions on the coefficients and,(More)

In this paper, we would like to derive a quantitative uniqueness estimate, the three-region inequality, for the second order elliptic equation with jump discontinuous coefficients. The derivation of the inequality relies on the Carleman estimate proved in our previous work [5]. We then apply the three-region inequality to study the size estimate problem(More)
