Lesiones premalignas y malignas del cuello uterino en jóvenes

Objetivo. Determinar la incidencia anual de CCU en <25 años en la región oeste de la Provincia de Pinar de Río (2004-2008). Material y método. Estudio longitudinal, descriptivo y transversal de todas las biopsias efectuadas en el Hospital General “Abel Santamaría” de Pinar del Río en los años 2004-2008 (N=554) para conocer además la causa de referencia, residencia, diagnósticos. Se resumen los resultados en cifras absolutas y relativas porcentuales y cuando necesario se compararon mediante X2 y Kappa al 95 % de certeza. Resultados. Anualmente acuden a la consulta 100 mujeres (X2=7,22; p=0,12) fundamentalmente de Pinar del Río (45,8%) por enrojecimiento cervical el 63,0 %. La lesión acetoblanca era frecuente (61,0 %). Predominaron las lesiones de bajo grado de malignidad en los ponches y de alto grado en la radiocirugía. Se detectaron 206 lesiones de bajo grado de malignidad (40,7%), 141 lesiones de alto grado (27%), 1 carcinoma escamoso microinvasor (0,3%) y 4 en estadio Ib (0,7%).Los diagnósticos colposcópicos e histopatológicos estuvieron asociados (Kappa=0.50; p<0,05). La incidencia anual de cáncer invasor (Ia y Ib) fue de 2,7 x 100 000 mujeres. Conclusiones. La tasa de CCU es baja en este grupo, pero es necesario incrementar la búsqueda activa de lesiones macroscópicas en la Atención Primaria de Salud para lograr disminuir la incidencia del CCU en general en la población femenina pinareña. La colposcopía es importante ya que no pesquisa este grupo en el Programa. La prueba visual del cuello con ácido acético pudiera incrementar la frecuencia de detección de lesiones

Study of the productivity enhancement initiative, engineering the workplace

The Naval Supply Systems Command (NAVSUP) operates stock points all over the world. Resources expended for the physical distribution function at these stock points amount to millions of dollars per year. It is imperative that these stock points operate to provide higher productivity at lower costs. Engineering the Workplace (ETW) is the productivity enhancement program NAVSUP feels will accomplish this. Comparing ETW with past productivity improvement programs within the Navy as well as current industry proven productivity improvement programs is the method used to determine the requirements and feasibility of its implementation. ETW is built on sound, proven industrial engineering techniques. Commercial productivity improvement programs can be adapted for use at government physical distribution activities. With proper headquarters support and with properly trained, well informed and supportive employees, ETW should be a successful program.http://archive.org/details/studyofproductiv00higgLieutenant, United States NavyMajor, United States Marine CorpsApproved for public release; distribution is unlimited

Arch 002

Arch 002 describes a design research investigation using off-the-shelf high-density polyethylene drainage pipe as a flexible concrete casting formwork through a process oscillating between digital design, physical fabrication, and digital fabrication methodologies. Through this process, the project team generated hypothetical architectures that serve to further develop their material counterparts. Drawing on contemporary casting technologies and historical structural modelling techniques, the experiments suggest a system for the encoding mass and force into three-dimensional forms, creating structures that serve as drawings of their creation process. Exploring notions of the readymade and postprocessing, the research explores iterative processes of making to transform normative construction components into transcendent material experiences
