RESUMO
El objetivo de este trabajo fue determinar la utilidad de tres pruebas inmunodiagnósticas (Inmunodifusión doble en gel, aglutinación con látex e inmunofluorescencia directa) para la detección de las micosis sistémicas (histoplasmosis, paracoccidioidomicosis, criptococosis y neumocistosis) en pacientes VIH/SIDA del Hospital Militar "Dr. Carlos Arvelo". Se realizó un estudio retrospectivo, de corte transversal y descriptivo de las historias micológicas de los pacientes atendidos en el Departamento de Infectología del Hospital Militar "Dr. Carlos Arvelo" con diagnóstico de las micosis sistémicas durante 3 años (2007-2009). Se analizaron los datos clínicos, paraclínicos, estudios micológicos y complementarios de los pacientes. La evaluación estadística se realizó mediante medidas de tendencia central, Tablas de contingencia (2 x 2), y la prueba Exacta de Fisher de 2 colas. Se revisaron las historias de 461 pacientes, de ellos 245 con VIH/SIDA y 21 casos que presentaron micosis sistémicas. No hubo diferencias estadísticamente significativas (p>0,05) al comparar la capacidad diagnóstica de las pruebas inmunodiagnósticas entre los pacientes con y sin VIH/SIDA. Las pruebas inmunodiagnósticas son de gran utilidad para la detección de las micosis sistémicas en pacientes VIH/SIDA. La cuantificación de anticuerpos o antígenos, tiene importancia pronóstica y diagnóstica, además, ayuda a evaluar la respuesta al tratamiento.
The purpose of this work was determine the utility of three inmunodiagnosis tests (immunodiffusion, latex agglutination and Direct immunofluorescence) for detection of histoplasmosis, paracoccidioidomycosis, cryptococcosis and pneumocystosis in AIDS/HIV patients from Military Hospital"Dr,Carlos Arvelo" .It was carried out a retrospective ,descriptive, transverse study of the mycological stories of the attended patients in the Department of Infectology from Military Hospital"Dr.Carlos Arvelo" with systemic mycoses diagnostic during 3 years(2007-2009).The clinical, paraclinical, mycological and complementary data and studies of patients with systemic mycoses were anylized .The statistic evaluation was realized by the means of central tendency measures. Comparisons were done applying Chi Square and exact Fisher test and contingency tables (2x2). 461 patients were reviewed, 245 with AIDS/HIV (21 were (+) for systemic mycoses). There were not significant statistic differences (p>0, 05) once the diagnosed capacity of the immunodiagnostic tests of the patients with and without AIDS/HIIV were evaluated. The immunodiagnostic tests are of great utility for the diagnosis of systemic mycoses in AIDS/HIIV patients. The quantification of antibodies or antigens, have prognostic importance and helps to evaluate the responses to the treatment. .

Changes in ovarian histology during the reproductive cycle of the viviparous lizard Sceloporus torquatus torquatus are described. In general, the variation in follicular histology observed during the seasonal cycle is similar to that of other lizards. Sceloporus t. torquatus exhibits a cycle in which small, previtellogenic follicles exist in the ovary from December to August. Vitellogenesis occurs between September and November, followed by ovulation from late November to early December. Parturition occurs the following spring. After ovulation, the remaining follicular cells form the corpus luteum and luteolysis did not occur until April-May. Follicular atresia is commonly observed in previtellogenic follicles with polymorphic granulosa, but occurs less frequently in follicles during late vitellogenesis. There are two germinal beds in each ovary. The yolk nucleus is evident in young oocytes as is a vacuolated ooplasma prior to vitellogenesis. Extensive polymorphism is observed in yolk platelets. Mast cells and secretory cells are observed in the thecal layer of the follicular wall as are melanocytes in the ovarian stroma. © 1995 Wiley-Liss, Inc.
