ABSTRACT
The VestaBlate system uses a multielectrode intrauterine balloon as a device to create effective and safe endometrial ablation (EA). The surface of the distensible balloon is impregnated with thermistors and thin, platelike electrodes. It is designed to deliver low-power electroenergy to the endometrium. Unlike the resectoscope techniques that require nonelectrolytic fluids for uterine distention, moving electrodes at high power outputs, and other variables that are operator dependent, the VestaBlate is computer controlled using a standard type electrosurgical generator. A respiratory enzyme stain, nitroblue tetrazoleum, was used to determine the extent and depth of tissue necrosis to a myometrial depth of 2 to 4 mm with uniform destruction of tissue with power setting at 45 W for a 4-minute application of energy. Sixty-nine patients have been treated, with 45 followed for at least 3 to 9 months. The amenorrhea rate is 40%; the oligomenorhea-hypomenorrhea rate is 49%.

Este estudio se trata de determinar el valor de la citologia del liquido amniotico en el diagnostico prenatal del sexo. Para este proposito se analizaron 100 muestras de liquido amniotico obtenidas por amniocentesis y puncion transcesarea, en el ultimo trimestre del embarazo. Se demostro una diferencia significativa en las citologias de fetos femeninos y masculinos, ya que en los primeros se encontro un mayor numero de celulas, con predominio de celulas intermedias basofilas y celulas naviculares, en comparacion con la menor cantidad de celulas y el predominio de celulas escamosas intermedias y superficiales acidofilas con ausencia de celulas naviculares en los fetos masculinos. En total se logro un diagnostico prenatal correcto del sexo en 99 por ciento de los casos.Se concluye que la citologia del liquido amniotico es un metodo rapido, sencillo y barato con una alta predictibilidad en el diagnostico del sexo fetal en el tercer trimestre del embarazo
