Meningococcal Disease in Children in Argentina A 3-year Active Sentinel Hospital Surveillance Study.

Background: Meningococcal disease (MD) is a medical emergency and a serious public health problem. As new meningococcal vaccines become available, MD surveillance is crucial to provide baseline epidemiologic data before implementing preventive measures. We estimated MD incidence and epidemiology in Argentina using hospital-based surveillance.

[Cerebral sparganosis in a child: case report].

We are reporting the case of an 8-year-old boy with history of seizures in whom the pathology exam of 2.5 by 3 cm surgical specimen obtained from a cortical-subcortical area of the de right occipital lobe showed a chronic granulomatous inflammatory process with a Spirometras pp larva. The patient was born and lived several years at a rural area of Tarija (Bolivia).

High frequency of primary mutations associated with antiretroviral drug resistance in recently diagnosed HIV-infected children.

Introduction: The aim of our study was to analyse the frequency of primary mutations associated with HIV drug resistance in a population of children born to HIV-infected mothers.

Design: A prospective study included newly HIV-diagnosed children treated at two public paediatric hospitals.

Patients And Methods: Clinical and antiretroviral therapy (ART) data were collected in mother-child pairs.

Pertussis in Argentina and France.

We have studied the epidemiology of pertussis in two countries, Argentina and France, which have similar histories of long-term mass vaccination with a whole-cell vaccine. Both countries display a comparable epidemiology, with an increase of the incidence of the disease in non-vaccinated newborns. We used pulsed-field gel electrophoresis (PFGE) analysis and genotyping to compare Bordetella pertussis clinical isolates recovered in Argentina and France in 2001-2004.

Epidemiological and molecular evidence of two events of father-to-child HIV type 1 horizontal transmission.

HIV-1 infection in children less than 15 years of age is mainly due to mother-to-child transmission. The aim of this work was to investigate molecular evidence to prove father-to-be horizontal transmission in two possible events of transmission. In the first event a boy was identified as HIV infected at 2-3 years of age.
