Abstract: El propósito en este trabajo es evaluar la electrocauterización de la membrana de Bowman como alternativa quirúrgica en el tratamiento de la queratopatía bullosa dolorosa. Se estudiaron 30 ojos de 30 pacientes con diagnóstico de queratopatía bullosa dolorosa que no habían logrado mejoría con los tratamientos habituales. Se tomaron como variables fundamentales la edad, el sexo, la etiología, el tiempo de evolución, la epitelización, las complicaciones y el alivio sintomático, los datos se tabularon de forma manual teniendo en cuenta el universo de pacientes. Predominó la queratopatía bullosa posquirúrgica (afáquicas y pseudofáquicas) en el 83,3 % de los pacientes. Las edades más afectadas fueron los mayores de 60 a os (63,3 %); no se encontraron diferencias significativas en cuanto al sexo. El tiempo de epitelización fue de 7 a 14 días en el 93,3 % de los pacientes y solo se encontraron complicaciones en el 14 % que no fueron de gravedad. El alivio de los síntomas se produjo en el 66,6 % en la primera semana del posoperatorio.

Journal of Biomedical Science and Engineering (JBiSE) , 2017, DOI: 10.4236/jbise.2017.1012042
Abstract: One of the great advantages of electrospun fibers is the large tridimensional area produced, capable of storing any type of material. The aim of our investigation is to study the electrospinning technique to produce polymer membranes for drug delivery applications, given their large surface area and ability to transport a bioactive compound. A mathematical modeling of the delivery system kinetics was also studied to find the mechanism that controls the releasing process. Results showed that electrospinning could provide regular and smooth membranes suitable for drug delivery processes. The mathematical modeling also proved that thicker PLLA membranes exhibited a Fickian diffusion behavior during the drug transport, presenting better control in drug delivery processes.

Abstract: Introduction. Previous research has demonstrated the presence of Paragonimus spp. in crabs of three municipalities located in the Medellín river basin. To design a plan for the control and prevention of paragonimosis, parasite presence must be demonstrated in the upper area of the river, and an awareness campaign of its risks must involve the participation of the educational community in focusing attention on the local aquatic resources. Objective. The presence of Paragonimus spp. metarcercariae was established in freshwater crabs from La Miel and La Clara streams, and an awareness campaign created public awareness to management of the aquatic ecosystems for risk reduction. Materials and methods. Nine crabs were collected from streams of La Miel and La Clara villages in 2007 and 2008. The crabs were indentified, sacrificed in the laboratory and examined for presence of Paragonimus spp. metacercariae. Five workshops were conducted with students of educational institutions of the two villages to improve the student perception of paragonimosis risks associated with the local streams. Results. The crabs were identified as Hypolobocera bouvieri. One crab was found with Paragonimus spp. in La Miel. A mollusk, Aroapyrgus colombiensis, another host of the parasite was found in La Clara. That aquatic ecosystems are a great attraction for the local was well established. Conclusions. Foci of Paragonimus spp. flatworms are present in the upper area of Medellín river which includes Caldas. However, local school children were uninformed about the risk of paragonimosis associated with the local aquatic ecosystem. Therefore this province must be included in programs for prevention and control of paragonimosis. The prevalence of this disease recommends educational programs that promote awareness of local aquatic ecosystems and their parasitic inhabitants. Introducción. Estudios previos demostraron la presencia de Paragonimus sp. en cangrejos de tres municipios en la cuenca del río Medellín. Para dise ar un plan para el control y la prevención de la paragonimosis, es necesario determinar la presencia del parásito en la parte alta del río, con la participación de la comunidad educativa, para dirigir su atención hacia el recurso hídrico. Objetivo. Establecer la presencia de metacercarias de Paragonimus sp. en cangrejos de las quebradas La Miel y La Clara, y sensibilizar a la comunidad educativa hacia el manejo adecuado de sus ecosistemas acuáticos. Materiales y métodos. En 2007 y 2008 se recolectaron cangrejos de quebradas de las veredas La Miel y La Clara. En el laboratori
