Abstract: Se realizó una revisión bibliográfica sobre las pautas de tratamiento recomendadas en la infección causada por Helicobacter pylori. Las altas tasas de erradicación logradas por los esquemas triple y cuádruple, hacen que éstos sean utilizados como primera y segunda línea de tratamiento respectivamente. Se relacionan las afecciones asociadas con la infección, en las que se debe utilizar el tratamiento erradicador. El uso de antimicrobianos, en zonas donde la resistencia era elevada, redujo la eficacia del esquema utilizado. La vacuna anti-H. pylori constituyó una novedosa opción de tratamiento. La utilización de diferentes sitios mucosos de vacunación con adyuvantes de baja toxicidad, también se trataron en este trabajo. La efectividad terapéutica de la vacuna, según los autores, resultó alta en modelos experimentales y alcanzó 100 % de protección frente a la infección por esta bacteria gramnegativa.

Abstract: Introducción: la frecuente incidencia de Enterococcus en los hospitales y su creciente resistencia antimicrobiana a nivel mundial, ha incrementado la necesidad de su vigilancia y control intrahospitalario, por lo que resulta imprescindible contar con medios diagnósticos más sensibles y exactos. Objetivo: ampliar la evaluación de la funcionalidad del medio cromogénico CromoCen ENT para el aislamiento e identificación de Enterococcus spp. procedentes de muestras clínicas. Métodos: se analizaron 150 muestras clínicas (orina, sangre, fecales, exudados vaginales, exudados de lesiones de piel y de catéteres) desde enero hasta abril de 2010, empleando el medio cromogénico y los medios convencionales correspondientes como controles, se evaluó la incidencia de Enterococcus spp. Se identificaron los aislamientos con un conjunto de 12 pruebas bioquímicas. A partir de los datos de la identificación bioquímica se determinaron los indicadores de calidad tanto para el medio CromoCen ENT como para los medios de referencia. Resultados: el medio cromogénico promovió el crecimiento de Enterococcus spp. en solo 24 h, lo cual permitió su fácil reconocimiento por la coloración rosada de las colonias. Los indicadores de calidad diagnóstico mostraron valores superiores a 95 %. El mayor porcentaje de aislamientos se obtuvo en las muestras de orina. Enterococcus faecalis resultó la especie mayormente encontrada en el total de las muestras. Conclusiones: CromoCen ENT permitió la correcta y rápida identificación de Enterococcus spp. procedentes de diversas muestras clínicas.

Abstract: Las dolencias producidas por la caries dental y otras afecciones bucales son múltiples, lo que hace al paciente acudir a los servicios de urgencia. El propósito de este trabajo fue evaluar la relación del estreptococo mutans y lactobacilo y algunas variables demográficas con la caries dental en ni os, pertenecientes a cinco consultorios del área de Contreras, del municipio de Matanzas, para lo cual se realizó un estudio analítico del tipo de casos y controles. La muestra se obtuvo mediante un dise o muestral probabilístico estratificado polietápico y quedó conformada por 900 ni os (300 casos y 600 controles) de 6 a 12 a os de edad. Hubo un predominio de ni os en las edades de 6 a 8 a os, tanto en los casos como en el grupo control, y no se observaron diferencias significativas entre ambos grupos. El sexo femenino prevaleció en los controles, y el masculino, en los casos. Los ni os pertenecientes al grupo de casos, tenían un alto grado de infección por estreptococo mutans y lactobacilos, y se demostró asociación positiva de la caries dental con estas variables. Se dise ó una estrategia educativa para evaluar y elevar el nivel de información que sobre esta enfermedad tenían los ni os objetosde estudio.
