Dynamics of homemade aortic endografts: in vivo study in humans with computed tomography scanner modeling.

Background: Several cases of aortic endograft rupture have been described. In most cases, they stem from component wear and perforation of the graft, leading to leakage. Friction of the stents on the graft can cause abrasion and perforate the textile.

Modern concepts of normal language and impairments.

Language is a primary factor in comprehending the functional organization of the brain. Starting with the static anatomoclinical model, followed by the limited aphasiological model, functional imaging techniques have allowed a more dynamic approach that adds complexity to the study of the interaction between brain and language, and bespeak the influence of parameters such as age, sex, motivation, and stress.

[Langerhans cell histiocytosis in an adult patient associated with sclerosing cholangitis and cerebellar atrophy].

Langerhans' cell histiocytosis is a disorder in children or young adults, characterized by clonal proliferation of histiocytic cells, staining for CD1a, with uni or multifocal organ involvement. It's a rare condition in adults. We report a case of Langerhans' cell histiocytosis in an adult with sclerosing cholangitis which rapidly progressed to fatal liver failure and progressive cerebellar atrophy.
