ABSTRACT

La silicona líquida está formada por polímeros de dimetilsiloxano.El uso de esta sustancia para el aumento de tejidosblandos como es la mamoplastia de aumento, puede ocasionarla aparición de granulomas, entre otros efectos indeseables.También dificulta posteriormente el diagnóstico tempranodel cáncer de mama. La técnica diagnóstica más aceptadaes la resonancia magnética. El tratamiento sintomático y etiológicode las complicaciones (eliminar la sustancia inyectada)presenta problemas difíciles de resolver. Presentamos dos casosde complicación aguda por reacción a cuerpo extraño trasinyección intramamaria de silicona líquida(AU)


Liquid silicone is derived from dimethylsiloxane polymers.The use of this substance to augment soft tissues as breastaugmentation is associated with the appearance of granulomas,among other undesirable effects. Its use also leads toenormous difficulty in the early diagnosis of breast cancer.Magnetic resonance has become the most accepted test fordiagnosis. The symptomatic and etiological treatment (removalof injected substance) presents problems that are difficult tosolve. We present two cases of foreign body reactions as anacute complication after intramammary injection of liquid silicone(AU)

ABSTRACT

El sistema enzimático del citocromo P-450 es el principalresponsable del metabolismo hepático de hormonas sexuales.Presentamos el caso de una paciente de 39 años que acude aconsultas externas de Cirugía por presentar mastalgia cíclicaintensa desde hace meses, que cede coincidiendo con la tomade itraconazol y recidiva al dejar este tratamiento. Se trata deun efecto paradójico puesto que, en este caso, el itraconazolse comporta como un inductor de la isoenzima CYPA3A4 aumentandola eliminación del estradiol y no como el inhibidorque es habitualmente(AU)


The enzymatic system of the cytochrome P-450 is the mainresponsible for the hepatic metabolism of sexual hormones.We present the case of a 39 year-old patient. She went to SurgeryService because she suffered recurrent intense cyclic breastpain during several months. She started itraconazol therapyand breast pain improved, but it relapsed when sheleaved the treatment with itraconazol. This is supposed to be aparadoxical effect because in this case itraconazole behaved asan inductor of the CYPA3A4 isoenzyme increasing the eliminationof the estradiol, and it did not behave as an inhibitor ofCYPA3A4, as habitually(AU)
