Abstract: Actualmente existen alrededor de 350 millones de personas con hepatitis crónica B en el mundo, ésta es causa frecuente de la hepatitis crónica, cirrosis hepática y carcinoma hepatocelular. Objetivos: caracterizar las alteraciones histopatológicas de hepatitis B crónica en el Hospital General Docente "Abel Santamaría Cuadrado" desde enero de 2002 hasta diciembre de 2009. Dise o: se estudiaron las biopsias con el diagnóstico de hepatitis viral crónica mediante un dise o retrospectivo y transversal. Método: universo: 259 biopsias diagnosticadas como hepatitis viral crónica. Muestra: 126 biopsias diagnosticadas como hepatitis B crónica. Se determinaron la edad, el sexo, lesión histológica y correspondencia diagnóstica entre grado de lesión histológica y estadio de fibrosis con la edad. Se usó la estadística descriptiva para resumir las variables categóricas y cuantitativas, cálculos de comprobación de frecuencias y/o asociaciones de variables X2, OR. Resultados: se elaboraron dibujos histológicos representativos de la clasificación de hepatitis viral crónica (Ishak, 1995). La hepatitis B crónica se diagnosticó más en los hombres de 35 a 44 a os en el período estudiado. En todos los parámetros de necrosis e inflamación fue más frecuente el de 1 punto, predominó la actividad necroinflamatoria mínima que alcanzó el 34,9 %. Se observó más la fibrosis ligera. Conclusión: se comprobó que el sistema de dibujos posibilita mejor estandarización del diagnóstico en un colectivo. La hepatitis B crónica fue más frecuente entre 35-44 a os, sexo masculino, con un predominio de la actividad necroinflamatoria mínima y fibrosis ligera. Nowadays 350 millions of people suffer from chronic hepatitis B all over the world; this is a frequent cause of chronic hepatitis, hepatic cirrhosis and hepatocellular carcinoma. Objective: to characterize the histopathological alterations of chronic hepatitis B at "Abel Santamaria Cuadrado" University Hospital from January 2002 to December 2009. Design: biopsies having the diagnosis of chronic viral hepatitis by means of a retrospective and cross-sectional design were analyzed. Method: the target group included 259 biopsies with the diagnosis of chronic viral hepatitis and the sample contained 126 biopsies with the diagnosis of chronic hepatitis B. Age, sex, histological lesion and in correspondence with the diagnosis between the histological degree of the lesion and fibrosis stage according to the age. Descriptive statistics was used to sum up categorical and quantitative variables as well as calculations to confirm frequencies and/or associ

Abstract: Se realizó un estudio en dos etapas: una primera de casos y controles, analítica y transversal, y una segunda de etapa de intervención longitudinal, prospectiva en los pacientes con forunculosis recidivante. El universo lo constituyeron los pacientes menores de 20 a os que asistieron a la consulta de inmunología en el periodo 2006-2010. La muestra fue de 89 pacientes con forunculosis que accedieron a participar en el estudio, y un grupo control de 182 pacientes con síntomas respiratorios ligeros. Se precisó la edad, género, color de la piel y los valores de inmunoglobulinas. Se realizó un exudado nasofaríngeo a convivientes. Se impuso el tratamiento en tres grupos: uno solamente con antibióticos específico para la forunculosis, un segundo grupo recibió tratamiento de convivientes y un tercero del abordaje del segundo grupo, recibió el uso de inmunomoduladores. Los resultados mostraron una asociación de la forunculosis a los ni os de mayor edad y de color de piel blanca, además de mostrar una asociación estadística muy significativa entre la presencia de al menos un conviviente con exudado positivo a Staphylococcus aureus (S. aureus) y la posibilidad de desarrollar la forunculosis recidivante. Se hace necesario el uso de antibióticos específicos combinados, el abordaje terapéutico de los convivientes y el uso de inmunomoduladores para lograr el éxito en el tratamiento. A two- stages study was conducted: the first included the cases and controls, analytical and cross-sectional; and the second stage with a longitudinal and prospective intervention in patients suffering from relapsing furunculosis. The target group was comprised of patients under 20 years old attending to immunology clinic during 2006-2010; the sample, 89 patients with furunculosis who agreed to participate in the study, and a control group of 182 patients with mild respiratory symptoms. Age, gender, skin colour, immunoglobulin levels and nasopharyngeal smear in those presenting coexistence were the variables analyzed. A treatment in three groups was followed: one (1) only with specific antibiotic therapy for furunculosis, besides a second group followed the treatment of those with coexistence, and a third one, with the approach of the second group receiving immunomodulators. Results showed furunculosis in association with children of older ages and white skin, besides a very significant statistical association with at least, one of them, showing coexistence with a positive smear of Staphylococcus aureus (S. aureus) and the possibility to develop relapsing furunculosis. Combined-specific an

Abstract: Se realizó un estudio descriptivo y longitudinal de todas las pacientes en la etapa climatérica que asistieron a la consulta de Ginecología del Policlínico Universitario "Luis Augusto Turcios Lima" del municipio Pinar del Río, del 1ro de enero al 31 de diciembre del 2005. El universo y la muestra lo constituyeron el total de pacientes en etapa climatérica que asistieron a esta consulta, que fueron 200 pacientes que se les llenó la historia clínica y dio seguimiento en consulta. Los datos se procesaron mediante análisis porcentual. Las pacientes que asistieron con más frecuencia a la consulta de climaterio fueron las que tuvieron una menopausia espontánea seguida de las de causa artificial. Los síntomas que más aquejan a estas pacientes son los agrupados a corto plazo. Las mujeres en esta etapa no reciben un adecuado apoyo familiar y la terapia más usada es la combinada, con un uso insuficiente de la actividad física y el deporte. La mayoría de las mujeres no reciben ayuda de un profesional de la cultura física, y tienen gran interés en pertenecer a grupos especializados de mujeres en esta etapa.

Abstract: abstract in cuba, the design of each construction includes the cover sealing system; although this system reflects in a very clear and precise way the use of mastiques for waterproof sealing, it has been identified that due to stability problems along its production a considerable percentage of these buildings are built with their joints unsealed. such a situation causes that 61% of these buildings nationwide present leak problems. to solve this problem, many mastiques have been obtained from different components such as oxidized-asphalt, turpentine, synthetic rubber, and organic solvents among others. today the mastic produced is not only inadequate to meet the present demand but also offered with quality problems like low ductility, high tendency to crystallize and the presence of organic solvents in its composition, which altogether reduce the waterproofing system durability. to overcome these drawbacks using the resin from the natural pine as the main component of the sealing mastic was the core idea in the attempt to obtain a product of asphalt mastic able to compete as to its rheological properties with those commercialized in the country. this study starts out with the chemical analysis of the main components of the mastic; then the various potential combinations are designed and characterized; eventually the mastic that best satisfied the requirements and norms established for this kind of products is obtained and its rheological properties evaluated.

Abstract: ResumenLa evaluación del comportamiento reproductivo en caninos permitemonitorear el trabajo en esta esfera, siendo trascendental la atención a la madre y la cría en el logro de una crianza eficiente. Para determinar la influencia del peso al momento del celo de una hembra sobre el peso al nacer y ganancia media diaria de las crías en diferentes momentos de la lactancia, se estudiaron los registros individuales de 10 hembras de la raza Pastor Alemán, para un total de 49 ciclos estrales, sometidas a similares condiciones de alojamiento, alimentación y sistema de reproducción intensiva. Se evidenció poca influencia del peso a la monta de la madre sobre la ganancia media diaria de las crías a la tercera semana, sin embargo existe una gran dependencia de dicha ganancia a la sexta semana de vida. Se encontró una relación débil entre el peso a la monta y peso al nacer de las crías, una mayor influencia mostró el tama o de la camada sobre el peso medio al nacimiento, no se observó dependencia entre el tama o de la camada y la ganancia media diaria a la tercera y sexta semana. El peso a la monta de la madre es de marcada influencia sobre la ganancia media diaria de las crías, a diferencia del peso al nacer, no existe diferencia entre los índices de crecimiento a la tercera y sexta semana, aún cuando el número de la camada influye sobre el peso al nacer de los cachorros.SummaryThe evaluation of reproductive behavior in dogs facilitates the work in this area. We study the relation of weight between the mother, just at the estrus time, and the birth weight, as well as the daily medium profit of the puppies at various laitance times. 10 German shepherd females were checked during theirs estrous cycles trough the individual records. We analyzed 49 estrous cycles, using similar conditions of shelter, food and intensive reproduction system. It showed little influence of the mother weight in relation to the daily medium profit of the puppies at the third week. Nevertheless, this relation was improved at sixth week. Likewise, the relation with the birth weight was weak. On the other hand, the litter size has a negative influence over the puppies’s birth weight and there is not dependence between the litter size and the puppies’ daily medium profit at the third and sixth week. The mother weight has a positive influence over the daily medium profit, unlike the birth weight. Also, there is no difference between the growth rates at the third and sixth week, even when the litter size influences on the birth weight of the puppies.
