METAPLASIA OSEA ENDOMETRIAL: CON SOSPECHA DIAGNOSTICA ECOGRAFICA O HISTEROSCOPICA
Corvalán A,Jaime; Sanhueza R,Pablo;
Revista chilena de obstetricia y ginecología , 2002, DOI: 10.4067/S0717-75262002000100006
Abstract: in this study we present 8 cases of patients in which the diagnosis of endometrial osseous metaplasia was suspected. four patients were asymptomatic, so the suspicion was based on the findings of routine transvaginal ultrasound. a diagnostic hysteroscopy was performed and the endometrial osseus metaplasia was confirmed by biopsy in two of them. in a fifth patient, an ultrasound was performed in her study of infertility where an osseous metaplasia was suspected. it was finally treated by means of resectoscopy under hysteroscopic vision and the lesion was confirmed later on. the remaining patients presented a negative transvaginal ultrasound for osseous metaplasia and diagnostic hysteroscopy was performed where endometrial ossification zones suggesting osseous metaplasia were observed. a resectoscopy of the lesions was carried out and an osseous metaplasia was confirmed in two of them. national and foreign literature is revised with special emphasis to diagnosis and treatment by ultrasound and histeroscopy

Abstract: abnormal uterine bleeding is an important symptom that can mean presence of endometrial cáncer or endometrial hyperplasia. the aim of this study is to assess the effectiveness of selected diagnostic methods in peri and potmenopausal women with abnormal uterine bleeding, and to propose a way to manage in these patients. different diagnostic methods are assessed, which include transvaginal ultrasonography, sonohysterography, doppler technique, magnetic resonance images, biopsy by pipelle, dilatation and curettage, and hysteroscopy. it is founded that ultrasonography has a high efficiency when it comes for identifying diffuse lesions, while sonohysterography has a high efficiency for identify focal lesions. on the other hand biopsy by pipelle has demonstrated to rule out diffuse pathology with a high efficiency. it is concluded that the best way to manage patients with abnormal uterine bleeding by performing ultrasonography and sonohysterography at the same time followed by a pipelle biopsy. finally, it can be suggested that by this way it is highly probable that all cases with endometrial carcinoma and endometrial hyperplasia can be identified
INTERGENERATIONAL MOBILITY OF INCOME AND SCHOOLING: CHILE 1996-2006
CELHAY,PABLO; SANHUEZA,CLAUDIA; ZUBIZARRETA,JOSE R;
Revista de análisis económico , 2010, DOI: 10.4067/S0718-88702010000200003
Abstract: in this paper we analyze intergenerational income and schooling mobility during the 1996-2006 decade in chile. using the countries most extended household panel survey, we overcome some of the limitations of the previous chilean studies by using observed income data for both parents and children, as opposed to observed income data only for children and income data that is generated for parents from the information given by their children retrospectively. following the recent literature, we control our estimates for time-series variation (lee and solon, 2009). our results show high intergenerational income elasticities in comparison to other developing countries, and these values are higher for sons than for daughters. the same results hold for educational mobility. trends analysis show that the transmission of economic status have remained constant during the last years in chile, while educational mobility has increased.

Abstract: Se presentan ocho casos de pacientes en las cuales se sospecha el dignóstico de metaplasia ósea endometrial. Cuatro de ellas son pacientes asintomáticas en las que se realizó la sospecha de metaplasia ósea por medio de una ecografía transvaginal realizada de rutina. Se realizó una histeroscopia diagnóstica confirmándose la metaplasia ósea endometrial por medio de biopsia en 2 de ellas. En una quinta paciente en su estudio por infertilidad se realizó una ecografía donde se sospechó metaplasia ósea, la que fue tratada mediante resectoscopia bajo visión histeroscópica, confirmándose posteriormente la lesión. Las tres pacientes restantes presentaban una ecografía transvaginal negativa para metaplasia ósea y se realizó una histeroscopia diagnóstica donde se observaron áreas de osificación endometrial sugerentes de metaplasia ósea, realizándose una resectoscopia de las lesiones, confirmándose la metaplasia ósea en dos de ellas. Se revisa la literatura nacional y extranjera con especial énfasis en el diagnóstico y tratamiento mediante ultrasonografía e histeroscopia de la metaplasia ósea endometrial.

EFICIENCIA DE LOS MéTODOS DIAGNóSTICOS EN EL ESTUDIO DEL SANGRADO UTERINO ANORMAL EN LA PERI Y POSTMENOPAUSIA

Abstract: El sangrado uterino anormal es un importante síntoma que puede indicar la presencia de cáncer o hiperpla-sia endometrial. El objetivo de este estudio es evaluar la eficiencia de los diversos métodos diagnósticos en pacientes peri y postmenopáusicas con sangrado uterino anormal y proponer una vía de manejo en estas pacientes. Diferentes métodos diagnósticos serán evaluados, incluyendo ecografíatransvaginal, sonohiste-rografía, Doppler, resonancia magnética nuclear, biopsia por Pipelle, dilatación y curetage e histeroscopia. Está demostrado que la ecografía transvaginal tiene una alta eficiencia para el reconocimiento de lesiones difusas, mientras que sonohisterografía tiene una alta eficiencia para identificar lesiones focales. Por otro lado, la biopsia por Pipelle ha demostrado descartar patología difusa con una alta eficiencia. Se concluye que la mejor vía para el estudio de pacientes con sangrado uterino anormal es realizar una ecografíatransvaginal y una histerosonografía en el mismo momento, seguido por una biopsia mediante Pipelle. Finalmente, puede ser sugerido que por esta vía es altamente probable que todos los casos de cáncer e hiperplasia endometrial puedan ser identificados Abnormal uterine bleeding is an important symptom that can mean presence of endometrial cáncer or endometrial hyperplasia.

Abstract: background: subfertility is a clinical condition which affects between 10-17% of couples during their reproductive age. amongst its causes, anovulatory factors are responsible for the 27% of the cases. in this aspect, subfertile couples should be investigated with the purpose of to rule out anovulation as subfertility cause. however, and in spite of decades of developments, to date there is no consensus on which test should be performed as a part of initial evaluation on these patients. objective: to critically evaluate the available tests to investigate the anovulatory factor as a component of the initial evaluation on subfertile patients. conclusion: the analysis of the evidence establishes that the determination of serum progesterone on day 23 of the menstrual cycle, is the test to perform in the initial assessment of ovulation in subfertile patients.

Abstract: Antecedentes: La subfertilidad corresponde a una condición que afecta entre el 10-17% de las parejas. Dentro de las causas, los factores anovulatorios corresponden al 27% de los casos. Las parejas subfértiles deben ser estudiadas con el fin de descartar el factor ovulatorio. No existe consenso en los exámenes que deberían ser realizados en la evaluación inicial del factor ovulatorio. Objetivo: Evaluar críticamente los exámenes disponibles para investigar el factor ovulatorio como parte de la evaluación inicial en las pacientes con subfertilidad. Conclusión: El análisis de la evidencia, establece que la determinación de la progesterona sérica en el día 23 del ciclo menstrual es el examen a realizar en la evaluación inicial de la ovulación en pacientes subfértiles.
