[Guideline for diagnosis and treatment of immune thrombocytopenia].

Management, outcome, diagnosis, prognosis and treatment of immune thrombocytopenia are controversial. Several guidelines stating different experts' opinions have been published; however, no worldwide consensus regarding the management of the disease has still been reached. This guideline defines diagnostic criteria, states initial laboratory tests, establishes differential diagnosis, develops topics concerning outcome and prognosis, and enumerates available treatments for acute and chronic disease, as well as for management of life-threatening bleeding.

Skeletal involvement in Gaucher disease: An observational multicenter study of prognostic factors in the Argentine Gaucher disease patients.

Patients with Gaucher type 1 (GD1) throughout Argentina were enrolled in the Argentine bone project to evaluate bone disease and its determinants. We focused on presence and predictors of bone lesions (BL) and their relationship to therapeutic goals (TG) with timing and dose of enzyme replacement therapy (ERT). A total of 124 patients on ERT were enrolled in a multi-center study.

Thrombosis in newborn infants.

The incidence of thrombosis is higher among newborn infants than in any other stage of pediatric development. This fact is the consequence of labile characteristics of the neonatal hemostatic system, in addition to exposure to multiple risk factors and the wide use of vascular catheters. Venous thromboses, which mainly affect the limbs, the right atrium and renal veins, are more frequently seen than arterial thromboses.

[Recombinant erythropoietin as treatment for hyporegenerative anemia following hemolytic disease of the newborn].

Introduction: The aim of the study is to report results of erythropoietin treatment for late hyporegenerative anemia in the hemolytic disease of the newborn (HDN). Reports previously published concern only a few cases, with controversial results.

Methods: Case series report concerning 50 neonates with HDN due to Rh, ABO or KpA antigens, aged more than 7 days.

Demographic data, natural history, and prognostic factors of idiopathic thrombocytopenic purpura in children: a multicentered study from Argentina.

Background: Demographics, outcome, and management of idiopathic thrombocytopenic purpura (ITP) in children present differences between countries. Although several factors influence outcome, it is impossible to predict at diagnosis which patients will have acute or chronic disease. High rates of spontaneous remission in chronic ITP have been reported.
