[New and "old" antiretroviral drugs in Pediatrics: new doses, formulations and associations].

Of the 25 antiretroviral drugs available in the market, only 16 are allowed for prescription in the pediatric patients. The antiretroviral, pertaining to the first three families, used for two decades, remain valid and are important components of antiretroviral therapy in naive children. We describe doses, presentations and current associations for these drugs in children, and also discuss new co-formulations that will reduce the number of doses, improve tolerance and therefore achieve better adherence of pediatric patients.

[Exfoliative erythroderma and infective dermatitis in an infant infected with human T-lymphotropic virus type I (HTLV I)].

We report a HTLV-I positive infant, whose infection was confirmed by polymerase chain reaction. The infant presented with an acute, severe, generalized eczema, exfoliation and severe erythroderma that yielded to an acute proteic malnutrition and frequent staphylococcal infections, unresponsive to treatment, since the second month of life. Immunodeficiencies from other origin and other causes of erythroderma were ruled out.

[Brucellosis in a student].

We describe the case of a student with a history of two and a half months of fever, hepatosplenomegaly, cutaneous, hematological and bone manifestations, within an epidemiological background compatible with the diagnosis of Brucellosis. Diagnosis of Brucella abortus was confirmed by serology and positive blood cultures. Clinical manifestations of brucellosis and diagnostic and treatment strategies are reviewed.
