RESUMEN
A two year-old female child was admitted at the Pediatric Intensive Care Unit in a septic shock associated with a lymphoproliferative syndrome, with history of fever, adynamia and weight loss during the last two months. On admission, the main clinical and laboratory manifestations were: pallor, jaundice, disseminated enlarged lymph nodes, hepatosplenomegaly, crusted warts on face, anemia, eosinophilia, thrombocytopenia, increased direct and indirect bilirubin, alkaline phosphatase, and gammaglutamyl transpeptidase. A parenteral administration of fluids, dobutamine and mechanical ventilation was started, without improvement of the clinical conditions. A direct examination of exsudate collected from cervical lymph node revealed numerous oval-to-around cells with multiple budding, like a "pilot wheel" cell, suggesting Paracoccidioides brasiliensis. Even though treatment with intravenous sulfamethoxazole-trimethoprine was soon started, the child died 36 hours after hospital admission. Disseminated paracoccidioidomycosis was confirmed in the autopsy. This is the youngest case of paracoccidioidomycosis in children reported in the literature.

Uma menina de dois anos foi internada em Unidade de Terapia Intensiva com o diagnóstico de choque séptico associado a sindrome linfoproliferativa febril, adinamia e perda de peso nos últimos dois meses. Na admissão, as principais manifestações clínicas e laboratoriais eram: palidez, icterícia, aumento ganglionar em todas as cadeias superficiais, hepatoesplenomegalia, lesões crostosas em face, anemia, eosinofilia, plaquetopenia, elevação de bilirrubina indireta e direta, de fosfatase alcalina e de gama glutamil transferase. A terapêutica instituída foi infusão de fluidos, dobutamina e ventilação mecânica, sem melhora das condições clínicas, seguido da introdução de sulfametoxazol-trimetoprina. O exame direto do linfonodo revelou numerosas estruturas ovaladas, com múltiplos brotamentos, como "roda de leme" sugerindo Paracoccidioides brasiliensis. A paciente evoluiu para o óbito 36 horas após a internação. Paracoccidioidomicose disseminada foi confirmada na necropsia. Trata-se do caso mais jovem de paracoccidioidomicose reportado na literatura consultada.

The DNA and nuclear antigens of Epstein-Barr virus (EBV) have been detected in specimens of tissue of non-Hodgkin lymphoma and lymphocytic interstitial pneumonitis from patients with acquired immunodeficiency syndrome. To determine whether there is serologic evidence of an active EBV infection in these disorders, we conducted a case-control study. The case patients were 10 children with acquired immunodeficiency syndrome and EBV genome-positive pneumonitis or lymphoma. We randomly selected one or, if available, two matched control patients with human immunodeficiency virus infection for each index patient and compared their EBV serologic profiles with those of the index case patient at the time of the biopsy. Ten case patients and 13 matched control patients were enrolled. All 10 case patients (100%) compared with 2 (15%) of 13 matched control patients had serologic evidence of either a primary or a reactivated EBV infection at the time the index patient had a biopsy performed (p less than 0.001). Therefore we found serologic and virologic evidence that EBV is etiologically related to EBV-associated lymphocytic interstitial pneumonitis and non-Hodgkin lymphoma in children with acquired immunodeficiency syndrome.

Serum samples were obtained in a 2-year period (November 1, 1984-December 31, 1986) from 136 Panamanian patients with hematologic malignancies identified by a population-based registry designed for studies investigating human T-cell lymphotropic virus (HTLV)-I. Only three patients had clinical and serologic findings of HTLV-I-associated adult T-cell leukemia/lymphoma (ATLL). The authors conclude that although classical HTLV-I-associated ATLL occurs in the Panamanian population, it is not as prevalent as in other Caribbean populations.
