[Brunner's gland adenoma: a rare tumor as cause of pyloric syndrome in an AIDS patient]. / Adenoma de glándulas de Brunner: un tumor raro como causa de sindrome pilórico en un paciente con SIDA.

Brunner's gland adenoma is a rare neoplasm that accounts for only the 0.008% of all benign duodenal tumors. Here we describe the case ofan HIV-seropositive man who developed a severe pyloric stenosis due to a Brunner's adenoma of the bulb and the first duodenal portion. Gastroduodenoscopy showed a large polypoid tumor that obstructed the pyloric region. The lesion was resected by surgery and a gastroduodenal anastomosis was made. The histopathologic examination of the surgical specimen showed a large proliferation of Brunner's glands into a large pedunculated polyp that confirmed the diagnosis of this hamartoma.

Meningitis por Candida parapsilosis en un paciente con sida. Informe del caso y revisión de los estudios publicados / Candida parapsilosis meningitis in a patient with AIDS. Report of a case and review of the literature

Antecedentes. Candida parapsilosis es una importante especie del género Candida que tiene un papel fundamental en el desarrollo de infecciones nosocomiales. En pacientes con infección por VIH, el compromiso del sistema nervioso central por hongos del género Candida es infrecuente. Caso clínico. En este artículo se presenta el caso de un paciente adulto con sida que desarrolló una meningoencefalitis por C. parapsilosis. Se describen las manifestaciones clínicas, los métodos de diagnóstico, el tratamiento antifúngico y la evolución. Conclusión. C. parapsilosis es un patógeno infrecuente como causa de meningitis en pacientes con sida. Un alto índice de sospecha y la realización de cultivos son necesarios para confirmar el diagnóstico de meningoencefalitis por levaduras del género Candida(AU)

Candida parapsilosis is an important species in the genus Candida that plays a significant role in hospitalized patients with nosocomial infections. In patients with HIV infection or AIDS, central nervous system involvement by Candida species is exceptional. Case report. Here we report a case of an acute meningoencephalitis due to C. parapsilosis in an adult patient with AIDS. We describe the clinical manifestations, the diagnosis methods, antifungal therapy and outcome. Conclusions. C. parapsilosis is uncommonly reported as a cause of meningitis in AIDS patients. A higher index of suspicion and culture is necessary to confirm the diagnosis of candidal meningoencephalitis(AU)

Non Hodgkin's lymphoma with cutaneous involvement in AIDS patients: report of five cases and review of the literature.

Cutaneous B cell lymphoma (CBCL) is a lymphoproliferative disorder of neoplastic B cell of the skin with a wide range of clinical manifestations. Commonly, the clinical features of CBCL are plaques, nodules, or ulcerative lesions. Skin is one of the common sites for extra-nodal lymphomas in patients with AIDS and B cell type is less common than T cell type. Only recently, the existence of B cell lymphomas presenting clinically in the skin without evidence of extra-cutaneous involvement has been accepted as primary CBCL. Here, we are presenting 5 patients with cutaneous involvement in the setting of HIV/AIDS disease. Two of them were primary cutaneous non-Hodgkin lymphomas. All were CBCL; 3 were immunoblastic, 1 was plasmablastic, and the other was a Burkitt lymphoma. We analyzed the epidemiological, clinical, virological, and immunological characteristics of this group of patients.

Disseminated nocardiosis with psoas abscess in a patient with AIDS: first reported case

Psoas muscle abscess is an uncommon infection that have been diagnosed increasingly in the last years. We present a case of a patient with advanced human immunodeficiency virus infection who developed a disseminated infection due to Nocardia asteroides sensu stricto type VI with psoas abscess. To our knowledge no other cases of Nocardia psoas abscess in the setting of HIV infection have been reported in the literature.

O abscesso do músculo psoas é uma infecção pouco comum que tem sido diagnosticada de maneira crescente nos últimos anos. Apresentamos um caso de paciente com infecção avançada pelo vírus da imunodeficiência humana (HIV) que desenvolveu uma infecção disseminada por Nocardia asteroides senso estrito tipo VI, com abscesso no psoas. Em nosso conhecimento, não foram relatados na literatura outros casos de abscesso do psoas por Nocardia, no contexto da infecção por HIV.

Compromiso ocular en el sarcoma de Kaposi asociado con el SIDA / Ocular manifestations of Kaposi´s sarcoma associated with the acquired immune deficiency syndrome

FUNDAMENTO. Evaluar la incidencia del compromiso ocular en el sarcoma de Kaposi asociado con el sida. MÉTODOS. Se revisaron las consultas efectuadas en el servicio de Oftalmología entre enero de 1994 y diciembre de 1998 por personas infectadas por el virus de la inmunodeficiencia humana (VIH). Todos ellos fueron sometidos a examen oftalmológico directo, fondo de ojo, biomicroscopia y examen con lámpara de hendidura. RESULTADOS. En 6.552 consultas, se diagnosticó compromiso ocular por el sarcoma de Kaposi en 17 pacientes, lo que significa una incidencia del 0,25 por ciento. La media del recuento de linfocitos T CD4 fue de 172 células /mm3. Las lesiones predominaron en el sexo masculino (88,23 por ciento). La estructura ocular afectada con mayor frecuencia fueron los párpados, siendo el inferior el más comprometido. En una de las mujeres afectadas, la localización ocular constituyó la primera y única manifestación de la neoplasia. CONCLUSIÓN. El compromiso ocular en el sarcoma de Kaposi es una alternativa que debe considerarse en sujetos con infección por VIH, con compromiso previo de piel y otras mucosas. Dada la escasa repercusión clínica de las lesiones, recomendamos efectuar un minucioso examen ocular en estos pacientes (AU)
