ABSTRACT

La silicosis es una enfermedad sin tratamiento. El programa de vigilancia de trabajadores expuestos a sílice está diseñado para detectarla lo más precozmente posible mediante una radiografía de tórax. A pesar de su rol fundamental, esta adolece de una gran variabilidad técnica y de interpretación. Para disminuir estos fenómenos, la OIT creó un sistema de clasificación ampliamente usado en Chile y el mundo. Este se basó en la radiografía análoga, la que ha sido reemplazada por el mismo set análogo, digitalizado. Si bien la OIT permite el uso de este nuevo tipo de imagen, indica que el patrón de comparación debe seguir siendo el análogo. Muchos estudios han demostrado que es mejor utilizar patrones de comparación digitales. El objetivo de este trabajo fue generar un set de radiografías digitales que representen las profusiones centrales de opacidades redondas del sistema de clasificación OIT. De un universo de 32.826 radiografías de pacientes expuestos a sílice, se obtuvo 252 radiografías, de las cuales 54 fueron informadas por 3 lectores acreditados, seleccionándose 8 casos que contaban con opacidades redondas puras de diferentes profusiones, las que se proponen como patrón digital para Chile.


Silicosis is a disease without treatment. The surveillance program for workers exposed to silica is designed to detect as early as possible by a chest radiograph. Despite its fundamental role, it suffers from a great technique and interpretation variability. To reduce these phenomena, the ILO created a classification system widely used in Chile and the world. This was based on analog radiography, which has been replaced by the same analog set, digitized. While the ILO permits the use of this new type of image it indicates that the pattern comparison must remain analog. Many studies have shown that it is best to use digital comparison patterns. The objective of this work was to generate a set of digital x-rays representing the central profusion of round opacities of ILO classification system. From a universe of 32,826 x-rays of patients exposed to silica, 252 films, of which 54 were reported for 3 accredited readers, selected 8 cases that had pure round opacities of different profusions was obtained, which are proposed as digital pattern for Chile.

ABSTRACT

We report a 23 years old male admitted to the hospital after a fall from a great altitude with severe trauma. During the second week of hospitalization he presented a severe nosebleed that did not respond to conventional tamponade. A selective angiography was performed and the branches of the internal maxillary artery were embolized in two occasions, stopping the bleeding. The patient was discharged from the hospital after 71 days of hospitalization
