Criptococosis diseminada en paciente HIV con CD4 mayor a 500 / Disseminated cryptococcosis among an HIV-Infected person with CD4 Higher than 500 cel/µ

La criptococosis es la micosis sistémica más frecuente entre los pacientes con HIV SIDA. Su prevalencia oscila entre el 5% y el 25%, de acuerdo con la región geográfica que se considere. La localización habitual de esta micosis en el paciente VIH es el sistema nervioso central (SNC). La diseminación sanguínea del agente causal ocurre ante defectos de la inmunidad mediada por células, asociándose con frecuencia a linfomas, leucemia, enfermedades del sistema retículo endotelial. A partir de la eclosión del HIV se redujo un aumento significativo del número de casos, transformándose esta última condición en la causa favorecedora más importante.

Cryptococcosis is the most frequent systemic mycosis among patients with HIV AIDS. Its prevalence ranges between 5% and 25%, according to the geographical region considered. The usual location of this mycosis in the HIV patient is the central nervous system (CNS). Blood dissemination of the causative agent occurs due to defects of cell-mediated immunity, frequently associated with lymphomas, leukemia, reticuloendothelial system diseases. From the emergence of HIV, there was a significant increase in the number of cases, with the latter condition becoming the most important favorable cause

Aracnoidits y quistes aracnoideos espinales múltiples. Revisión bibliográfica a propósito de un caso / ARACNOIDITIS AND MULTIPLE ARACNOID CYSTS : CASE REPORT AND REVISION OF THE LITERATURE

Los quistes aracnoideos son lesiones malformativas que contienen en su interior un líquido de características similares al líquido cefalorraquídeo. Constituyen alrededor del 1% de todos los procesos ocupantes de espacio a nivel intracraneal y, en menor número de casos pueden localizarse a nivel espinal. Presentamos una asociación de aracnoiditis espinal y posterior cavitación.

Arachnoid cysts are malformative lesions that contain a liquid with characteristics similar to cerebrospinal fluid. They constitute about 1% of all space-occupying processes at the intracranial level and, in a smaller number of cases, they can be located at the spinal level. We present an association of spinal arachnoiditis and posterior cavitation

Zoonosis en grupo familiar. Revisión bibliográfica a propósito de un brote Informe de casos / ZOONOSIS IN A FAMILY GROUP: LITERATURE REVIEW OF AN OUTBREAK

Brucelosis es una zoonosis de distribución mundial. Argentina notifica 300 casos anuales. Entre agosto y octubre de 2015 diagnosticamos tres casos en un grupo familiar

The aim of the present report was to describe an outbreak of Brucellosis in a family group due to its unfrequency and etiological value. The infection caused by Brucella is a disease of animals (zoonoses) , and humans are accidental hosts. The major determinant of a human risk of acquiring the disease is the contact with infected animals. The genus Brucella contains four species pathogenic for humans: B. melitensis, B. abortus, B. suis and B. canis. Brucella are intracellular bacteria and among the species pathogenic for humans, B. melitensis are the most virulent. The organisms commonly enter the body through cuts in the skin of people handing infected animals or through their blood or secretions, and also the entry can include the respiratory or gastrointestinal tracts. Brucellosis exists worldwide, and Argentina reports 300 cases annually. Between August and October 2015, we diagnosed four cases in a family group: these cases are reported in the article.

Quiste esplénico gigante. A propósito de un caso / GIANT SPLENIC CYST. CASE REPORT

La hidatidosis o equinococosis quística es una zoonosis causada por el cestode Echinococcus granulosus, responsable de importante morbilidad y mortalidad en todo el mundo. La presentación esplénica aislada tiene escasos reportes en la literatura mundial.

Hydatidosis or cystic echinococcosis is a zoonosis caused by the cestode of Echinococcus granulosus, responsible for significant morbidity and mortality worldwide. Isolated splenic presentation has few reports in the world literature. The aim of this report was to describe an unfrequent case of isolated splenic hydatidosis due to its etiologic value because of the inexistence of a simultaneous hepatic involvement
