[Hemorrhagic diseases in newborn infants]

In 2% of the newborn children, hemorrhagic or nonhemorrhagic events may appear. The wider range of paraclinical investigations used nowadays permitted a better knowledge of physiopathological bases of these diseases. The paper reports on all the forms of hemorrhage: vascular hemorrhages, disturbances of the thrombocytic function (congenital and acquired), thrombocytopenias (following a low medullary function, or an increased destruction and the mixed ones), thrombocytosis. Coagulopathies generated by congenital diseases, with lack of different factors of homeostasis, hemorrhages due to the liver diseases and DIC (disseminated intravascular clotting) are also dealt with. All the chapters review etiology, diagnosis, prognosis, treatment, prophylaxis. Tables with etiologic forms, investigation schemes for differential diagnosis and treatment complete each chapter.
