Neumotórax espontáneo y presión atmosférica
In order to assess factors associated with spontaneous pneumothorax (SP), mainly climatic changes, a prospective study was undertaken of 62 SP episodes among patients admitted to our hospital during a two-year period, from January 1994 to January 1996. Atmospheric pressure (AP) changes were analyzed, with daily recording of the number of unusual changes in AP (increases above 95th percentile and decreases below 5th percentile) and how many of these changes were followed by some episode of spontaneous pneumothorax during the following five days. To measure the degree of this association between the emergence of pneumothorax and exposure to unusual changes I AP, the relative risk (RR) was cal…
Tomografía computarizada de alta resolución en tuberculosis pulmonar con baciloscopia de esputo negativa
Marco de referencia La tuberculosis pulmonar con baciloscopia de esputo negativa plantea dificultades diagnosticas cuando no se dispone de medios liquidos de cultivo debido al lento crecimiento del Mycobacterium tuberculosis en los medios tradicionales de cultivo y a la necesidad de utilizar exploraciones invasivas. Objetivo Evaluar los hallazgos de la tomografia computarizada de alta resolucion (HRCT) en pacientes con tuberculosis pulmonar y baciloscopia de esputo negativa. Metodo Se estudiaron prospectivamente 28 pacientes (12 con tuberculosis activa y 16 inactiva) mediante HRCT, valorando los siguientes hallazgos: nodulos centrolobulillares, estructuras lineales ramificadas multiples, ma…
