ABSTRACT

Resumen El sangrado uterino posmenopáusico se define como aquel sangrado que ocurre después del cese definitivo de la menstruación en la etapa reproductiva de la mujer como consecuencia de la claudicación biológica de los ovarios, o como un sangrado no esperado en mujeres con terapia de reposición hormonal sistémica de la menopausia. Representa el 5% de las consultas ginecológicas y, si bien su origen suele ser por causas benignas, puede requerir una evaluación minuciosa para descartar patologías malignas del endometrio. El objetivo de este trabajo es establecer un flujograma diagnóstico basado en la evidencia para la evaluación de las pacientes con sangrado uterino posmenopáusico.


Abstract Postmenopausal uterine bleeding is defined as the bleeding that occurs after the last menstruation due to loss of ovarian function, or a non-scheduled bleeding in patients with hormonal therapy. It represents 5% of the gynecologic visits, and even though its origin is often benign, it requires a thorough evaluation to discard malignant diseases. The objective of these review is to propose a diagnostic algorithm based on the available evidence for the evaluation of patients with postmenopausal uterine bleeding.

ABSTRACT

El objetivo de la investigación fue establecer los factores de riesgo para cáncer de endometrio en premenopáusicas con diagnóstico de hemorragia uterina disfuncional. Se realizó un estudio observacional en mujeres con diagnóstico de hemorragia uterina disfuncional. Se evaluaron la asociación entre la histología endometrial y los factores de riesgo para el cáncer de endometrio, de ellos se analizaron: irregularidades del ciclo menstrual, diabetes mellitus, nuliparidad, hipertensión, obesidad y edad mayor de 40 años. La regresión logística se utilizó para investigar la importancia relativa de cada factor de riesgo. El estudio incluyó 266 mujeres con edad promedio de 41 años. La prevalencia de los factores de riesgo fue la siguiente: edad mayor de 40 años (67,2 %), menstruaciones irregulares (22,1 %), nuliparidad (16,9 %), obesidad (10,1 %), hipertensión (8,6 %) y diabetes (2,2 %). Los resultados de la biopsia endometrial incluyeron: 14 casos (5,2 %) de hiperplasia simple, 16 casos (6,0 %) de hiperplasia compleja y 4 casos (1,5 %) de hiperplasia con atipia. No se observaron casos de adenocarcinoma de endometrio. Se encontró que las menstruaciones irregulares eran el único factor de riesgo estadísticamente significativo asociado a alteración de la histología endometrial (p = 0,0132). En el grupo de pacientes con menstruaciones regulares y sin factores de riesgo, la incidencia de biopsia anormal observada fue inferior al 1 %. Las irregularidades del ciclo menstrual aumentan la probabilidad de un resultado anormal de la biopsia a un 14,2 %. Se concluye que las mujeres premenopáusicas diagnosticadas con hemorragia uterina disfuncional cuyos ciclos menstruales son regulares tienen un riesgo insignificante de desarrollar hiperplasia endometrial.


The objective of the research was to establish risk factors for endometrial cancer in pre-menopausal women with a diagnosis of dysfunctional uterine hemorrhage. An observational study was conducted in women with a diagnosis of dysfunctional uterine bleeding. The association between endometrial histology and risk factors for endometrial cancer analyzed were menstrual cycle irregularities, diabetes mellitus, nulliparity, hypertension, obesity and age over 40 years. Logistic regression was used to investigate the relative importance of each risk factor. The study included 266 women with an average age of 41 years. The prevalence of risk factors was the following: age over 40 years (67,2 %), irregular menses (22,1 %), nulliparity (16,9 %), obesity (10,1 %), hypertension (8,6 %) and diabetes (2,2 %). The results of the endometrial biopsy included: 14 cases (5,2 %) of simple hyperplasia, 16 cases (6,0 %) of complex hyperplasia and 4 cases (1,5 %) of complex hyperplasia with atypia. No cases of endometrial adenocarcinoma were observed. It was found that irregular menses were the only statistically significant risk factor associated with alteration of endometrial histology (p = 0.0132). In the group of patients with regular menses and without risk factors, the incidence of abnormal biopsy observed was less than 1 %. The irregularities of the menstrual cycle increases the probability of an abnormal result of the biopsy to 14,2 %. It is concluded that premenopausal women diagnosed with dysfunctional uterine bleeding whose menstrual cycles are regular have a negligible risk of developing endometrial hyperplasia.

ABSTRACT

Zebu and Holstein x Zebu crossbred have low incidence of uterine infection when compared to Holstein cows. Resistance to uterine infections may be associated with the ability to recognize invading microorganisms. Endometrial transcription of microbial molecular patterns receptors has been investigated in the postpartum period of Holstein cows, but it is completely unknown in Zebu or Holstein x Zebu cows. In this study, 9 Gyr and 12 F1 Holstein x Gyr cows were submitted to endometrial biopsies at the first and seventh days postpartum, with the objective to measure transcription levels of toll-like receptors (TLRs) 1/6, 2, 4, 5, and 9; nucleotide-binding oligomerization domain (NOD)-like receptors 1 and 2; and coreceptors cluster of differentiation 14 (CD14) and myeloid differentiation protein-2 (MD-2). There was a significant (P<0.05) decrease in transcription of TLR5 in Gyr, and an increase in transcription of TLR9 in F1 cows, between the first and seventh day postpartum. Both groups had low incidences of uterine infections up to 42 days postpartum. Uterine involution completed at 27.7 ± 10.1 and 25.1 ± 4.7 days postpartum for Gyr and F1 cows, respectively. In Gyr cows, higher transcription levels of TLR1/6 and NOD1 correlated to a longer period required for uterine involution. In F1 cows, lower levels of TLR1/6, TLR2 and NOD2 correlated to a longer period required for uterine involution. In conclusion, some pathogen recognition receptors associated significantly with the time required for uterine involution in Gyr and F1 cows.(AU)


Vacas Zebu e mestiças Holandês x Zebu apresentam baixas incidências de infecções uterinas quando comparadas às Holandesas. A resistência às infecções uterinas pode estar relacionada com a capacidade de reconhecimento dos microrganismos invasores. A transcrição endometrial de receptores de padrões moleculares microbianos tem sido investigada em vacas Holandesas recém-paridas, porém ainda é desconhecida em vacas Zebu e mestiças Holandês x Zebu. No presente estudo, nove vacas Gir e 12 F1 Holandês x Gir foram submetidas a biópsias endometriais no primeiro e no sétimo dia após o parto, com o objetivo de mensurar os níveis de transcrição gênica dos receptores tipo Toll (TLRs) 1/6, 2, 4, 5 e 9; receptores tipo NOD 1 e 2; e dos coreceptores CD14 e MD-2. Houve diminuição significativa (P < 0,05) do nível de transcrição de TLR5 em vacas Gir e aumento da transcrição de TLR9 em vacas F1, entre o primeiro e o sétimo dia após o parto. Os dois grupos apresentaram baixas incidências de infecções uterinas até 42 dias pós-parto. O período de involução uterina foi de 27,7 ± 10,1 e 25,1 ± 4,7 dias pós-parto, para vacas Gir e F1, respectivamente. No grupo de vacas Gir, altos níveis de transcrição de TLR1/6 e NOD1 tiveram correlação significativa com o prolongamento do período de involução uterina. No grupo de vacas F1, baixos níveis de transcrição de TLR1/6, TLR2 e NOD2 foram associados a maiores períodos de involução uterina. Portanto, os níveis de transcrição endometrial de alguns receptores de padrões moleculares microbianos na primeira semana após o parto podem estar relacionados com o tempo requerido para ocorrência da involução uterina em vacas Gir e F1.(AU)

ABSTRACT

Este estudo objetivou estabelecer a etiologia e achados clínico-patológicos das endometrites fúngicas. Para tal, realizou-se anamnese, exame ginecológico, cultura, citologia e biópsia endometriais em 85 éguas em idade reprodutiva e que não pariam havia um ano ou mais. Das 85 éguas, 24 (28%) apresentaram exames compatíveis com endometrite infecciosa. Destas, em 20% (5/24), confirmou-se endometrite com envolvimento fúngico. Os fungos isolados foram: Candida guilliermondii, C. tropicalis, C. pseudotropicalis associadas ao Bacillus sp. em uma égua; C. albicans em duas fêmeas (uma associada a Escherichia coli); um caso de Trichosporon penicillatum e um de T. capitatum. Todos animais diagnosticados com endometrite fúngica apresentaram inflamações endometriais moderadas, nos exames de citologia e no histopatológico, sendo estes achados compatíveis com o histórico e o exame reprodutivo destes animais. Destacou-se a presença constante de linfócitos e plasmócitos nos dois exames, assim como das lesões degenerativas no endométrio através da biópsia endometrial. Em 80% (4/5) constataram-se estruturas fúngicas na citologia endometrial, porém no exame histopatológico, não foi possível detectar tais estruturas. Após o estudo pode-se afirmar que a metodologia utilizada foi eficiente para diagnosticar a endometrite fúngica, com destaque para o exame de citologia endometrial, e que este tipo de endometrite teve caráter crônico em todos os animais.


The aim of the present study was to determine the causes and clinical findings of endometritis. The history, reproductive examination and endometrials culture, uterine cytology and biopsy from 85 mares in reproductive age that did not foal a year or more were performed. Twenty four (28%) out of 85 mares had signals compatible with infectious endometritis. From those, 20% (5/24) had fungal involvement, and the agents were: Candida guilliermondii, C. tropicalis, C. pseudotropicalis, in association to Bacillus sp. in one mare; two mares had C. albicans, and one of them associated with Escherichia coli; a case of Trichosporon penicillatum and another of T. capitatum. All animals with fungal endometritis presented moderate endometrial inflammation, at cytology and uterine biopsy, which was compatible with the animal's history and reproductive exam. The endometrial cytology and biopsy revealed numerous lymphocytes and plasmocytes as well as the degenerative lesions in the endometrial biopsy. Fungal structures were presented at the endometrial cytology smears in 80% (4/5) of the mares, however those structures were not detected in the biopsy. In conclusion, the methodology used was efficient to diagnose fungal endometritis, with standing for the examination of endometrial cytology, and the fungal endometritis had chronic character in all animals.

ABSTRACT

Introducción: la hiperplasia endometrial es la proliferación de las glándulas endometriales en tamaño y forma irregular, causada por una excesiva exposición a los estrógenos. Objetivo: caracterizar las hiperplasias endometriales en pacientes del Hospital Eusebio Hernández durante todo el año 2011. Método: se realizó un estudio observacional descriptivo. Se revisaron 2 842 informes histopatológicos en el Departamento de Patología del Hospital Ginecobstétrico “Profesor Eusebio Hernández” en Marianao, La Habana en el periodo comprendido entre el 1º de enero y el 31 de diciembre de 2011, de los cuales 1 269 correspondieron a biopsias de endometrio obtenidas por legrado. Resultados: en 154 de las biopsias endometriales (12,1 %) el diagnóstico fue de hiperplasia endometrial. El rango de edades de mayor frecuencia de diagnóstico fue el de las mujeres entre 41 y 50 años y en el mayor porcentaje de pacientes (84,4 %) se diagnosticó hiperplasia simple sin atipias; mientras que, el 7,1 % de los casos presentó atipias. El factor de riesgo más asociado fue la obesidad en 46,1 % de los casos. El ultrasonido tuvo una positividad en los casos con atipia endometrial del 90,9 % y la histeroscopia del 100 %. El tratamiento hormonal fue utilizado en el 67,5 % de las pacientes y el tratamiento quirúrgico se utilizó en la totalidad de las pacientes con atipias celulares. Conclusiones: hubo predominio de hiperplasia endometrial sin atipia en las mujeres con edades entre 41 y 60 años y con menor paridad y una baja ocurrencia de hiperplasia atípica.


Introduction: endometrial hyperplasia is a proliferation of endometrial glands in size and irregular shape, caused by excessive exposure to estrogen. Objective: to characterize the endometrial hyperplasia in patients at Eusebio Hernández Hospital in 2011. Method: a descriptive study was conducted. 2842 pathology reports were reviewed in the Department of Pathology, at ''Profesor Eusebio Hernández" Gynecobstetric Hospital in Marianao, Havana from January 1st to December 31st, 2011. 1269 of them were for endometrial biopsies obtained by curettage. Results: 154 endometrial biopsies (12.1 %) had the diagnosis of endometrial hyperplasia. The age range of diagnosis was more frequent for women between 41 and 50 years and the highest percentage of patients (84.4 %) were diagnosed with simple hyperplasia without atypia; while 7.1 % of the cases showed atypia. The associated risk factor was obesity in 46.1 % of cases. Ultrasound had positivity in patients with atypical endometrial 90.9 % and 100% hysteroscopy. Hormone therapy was used in 67.5 % of patients and surgical treatment was used in all patients with cellular atypia. Conclusions: there was a predominance of endometrial hyperplasia without atypia in women aged between 41 and 60 and with low parity and a low occurrence of atypical hyperplasia.

ABSTRACT

Demostrar la utilidad de la toma de muestra con Uterobrush® y compararlo con la biopsia endometrial, en pacientes posmenopáusicas con terapia hormonal. Estudio prospectivo durante un lapso de seis meses, en el cual se incluyeron 30 pacientes, de las cuales 15 referían sangrado genital anormal y 15 no referían sintomatología. A cada paciente se le realizó citología endometrial con Uterobrush® y posteriormente se le realizó biopsia de endometrio con cureta de Novak. El diagnóstico citológico se comparó con el diagnóstico biópsico, para obtener la sensibilidad y especificidad de la técnica con Uterobrush®. Consulta externa del Servicio de Ginecología del Instituto Autónomo Hospital Universitario de Los Andes (IIAHULA) Mérida. El procedimiento fue fácil en un 73,3 por ciento de las pacientes, no refiriendo dolor. No se presentó sangrado posterior a la introducción del Uterobrush® en un 53,33 por ciento. Las muestras fueron adecuadas en el 70 por ciento de los casos. La principal causa de limitación fue la mala preservación de las células. Al comparar los diagnósticos citológicos con la biopsia encontramos una sensibilidad del 71 por ciento y una especificidad del 75. La citología endometrial con Uterobrush® es un procedimiento aceptable, fácil de usar, económico, y bien tolerado por las pacientes; siendo útil para la valoración endometrial en mujeres posmenopáusicas y en aquellas que así lo ameriten, pero no se pretende desplazar a la biopsia endometrial sino sugerir estudios más extensos.

ABSTRACT

O trabalho teve como objetivo geral fazer um estudo comparativo da histologia endometrial e das concentrações plasmáticas de progesterona (P4) em éguas, repetidoras ou não de cio. A hipótese do presente estudo é que existe correlação entre o histórico de infertilidade, os achados histopatológicos e a concentração de P4 destes animais. Para tanto, foram utilizadas 36 éguas, em idade reprodutiva (3-23 anos), das raças Mangalarga Marchador e Campolina. Utilizaram-se éguas não repetidoras (n=11) como grupo controle, sendo 4 éguas doadoras e 7 receptoras; e repetidoras de cio (n=25), 15 doadoras e 10 receptoras. Tal classificação foi realizada de acordo com o histórico reprodutivo destes animais. Amostras de endométrio foram coletadas para a realização de avaliação histopatológica e amostras de sangue para a mensuração das concentrações plasmáticas de progesterona. Os fragmentos de tecido endometrial obtidos pela biópsia foram fixados no Fixador de Bouin. Posteriormente os fragmentos foram processados e incluídos em parafina. Os cortes foram corados por Hematoxilina-Eosina (HE) para exame histopatológico. As concentrações plasmáticas de P4 foram mensuradas pelo método de enzima-imunoensaio (ELISA). Não foi observada correlação entre as concentrações de P4 e a subfertilidade, sendo estas variáveis tratadas como independentes. Houve uma correlação positiva entre a idade e a subfertilidade (p<0.05), assim, quanto mais velha a égua, maior a subfertilidade. Foi observada uma correlação entre a categoria da biópsia e a subfertilidade (p<0.05), ou seja, quanto mais alterações histológicas, maiores as chances da égua ser subfértil. Contudo, nem todas as éguas classificadas na Categoria I e II levaram a gestação a termo e nem todas da Categoria III tiveram falhas na reprodução, pois, deve-se considerar que outros fatores podem influenciar na manutenção da gestação. A biópsia endometrial demonstrou ser uma técnica fácil, segura, barata e com um desconforto...


The study aimed to compare endometrial histology and plasmatic progesterone (P4) concentration of repeat breeds and healthy mares. The hypothesis was that there is a correlation between infertility and endometrial histology and P4 concentration in both groups. A total of 36 Campolina and Mangalarga Marchador mares in reproductive age (3-23 years) were used, 11 of them were healthy mares (Control group, 7 embryo recipient and 4 embryo donors), and 25 repeat breeders (10 embryo recipient and 15 embryo donors), classified as based on their reproductive history. Endometrial and blood samples were collected for respectively histological and plasma progesterone concentration evaluation. The endometrial samples obtained after biopsy were fixed in Bouin's fluid, processed, included in paraffin, and stained with Hematoxylin-Eosin (HE) for histopathological examination. Plasmatic progesterone concentrations were evaluated by enzyme immunoessay (ELISA). There was no correlation between progesterone concentration and fertility. But there was a positive correlation between age and fertility, as older mares had major tendency of subfertility than younger ones. There was also a correlation between biopsy categories and fertility, as more histological alterations were found, higher were the chances for the mares to be subfertile. However not all mares classified as Category I and II maintained pregnancy until parturition. Other factors could influence pregnancy maintenance. In the same way, not all mares in Category III were infertile. The endometrial biopsy was shown to be an easy and cheap diagnostic technique with minimal discomfort to the animals and, together with other data, to be a very important component in the investigation of mare fertility.

ABSTRACT

OBJETIVO: Correlacionar la histeroscopia con la biopsia dirigida en pacientes pre y postmenopáusicas con engrosamiento endometrial patológico al ultrasonido. MÉTODO: Estudio retrospectivo de 265 pacientes derivadas por engrosamiento endometrial patológico en la ecografía transvaginal y evaluadas mediante histeroscopia con biopsia dirigida. RESULTADOS: 68,7% de las pacientes presentaron un aspecto histeroscópico benigno, 15,1% normal, 10,6% potencialmente maligno y 5,6% maligno. Los diagnósticos anátomo patológicos más frecuentes fueron: pólipo endometrial (n=92; 34,7%), endometrio proliferativo/secretor (n=84; 31,7%) y mioma submucoso (n=38; 14,3%). Todos los cánceres endometriales (n=9) se presentaron en mujeres postmenopáusicas sin TRH y con endometrio 11 mm. La correlación entre histeroscopia y anatomía patológica para diagnóstico de patología benigna tuvo una sensibilidad y especificidad de 90,7% (95% IC 85,2 - 94,3) y 65,4% (95% IC 55,8 - 73,8); valor predictivo positivo y negativo fue de 80,2% (95% IC 73,8 - 85,4) y 82% (95% IC 72,3 - 88,7). Para diagnóstico de hiperplasia endometrial la sensibilidad y especificidad fue 60% (95% IC 31,3 - 83,2) y 91,4% (95% IC 87,3 - 94,2); el valor predictivo positivo y negativo fue de 21,4% (95% IC 10,7 - 39,5) y 98,3% (95% IC 95,7 - 99,3). Para diagnóstico de cáncer endometrial la sensibilidad y especificidad fue de 95% (95% IC 65,5 - 99,5) y 97,9% (95% IC 95,2 - 99); el valor predictivo positivo y negativo fue de 63,3% (95% IC 38,7 - 82,5) y 99,7% (95% IC 98,1 - 99,8). CONCLUSIÓN: El 85% de las pacientes con engrosamiento endometrial presentaron una histeroscopia alterada (benigna, potencialmente maligna o maligna), confirmada en 80% de los casos por anatomía patológica. En un centro con experiencia la histeroscopia normal puede hacer innecesaria la biopsia. El aspecto potencialmente maligno a la histeroscopia puede ser un sobrediagnóstico, por lo que la anatomía patológica es imprescindible. ...


OBJECTIVE: Comparison of hysteroscopy with biopsy in pre- and post -menopausic patients with endometrial thickening on ultrasound. METHODS: Retrospective study of 265 patients with pathologic endometrial thickening on transvaginal ultrasound and evaluated with hysteroscopy and biopsy. RESULTS: 68.7% of the patients had benign hysteroscopy results, 15.1% were normal, 10.6% were potentially malignant, and 5.6% were malignant. The most frequent biopsy results were: endometrial polyp (n= 92, 34.7%), proliferate / secretor endometrium (n= 84, 31.7%), and submucosal myoma (n=38, 14.3%). All of the endometrial cancers (n= 9) were in post- menopausic women, with no history of hormone replacement therapy and with endometrial thickening 11mm. Sensitivity and specificity for hysteroscopy in comparison to biopsy for diagnosing benign pathology were 90.7% (95% CI 85.2 - 94.3) and 65.4% (95% CI 55.8 - 73.8), and the positive and negative predictive values were 80.2% (95% CI 73.8 - 85.4) and 81.9% (95% CI 72.3 - 88.7). Sensitivity and specificity for hysteroscopy in comparison to biopsy for diagnosing endometrial hyperplasia were 60% (95% CI 31.3 - 83.2) and 91.4% (95% CI 87.3 - 94.2), the positive and negative predictive values were 21.4% (95% CI 10.7 - 39.5) and 98.3% (95% CI 95.7 - 99.3). Sensitivity and specificity for hysteroscopy in comparison to biopsy for diagnosing endometrial cancer were 95% (95% CI 65.5 - 99.5) and 97.9% (95% CI 95.2 - 99), positive and negative predictive values were 63.3% (95% CI 38.7 - 82.5) and 99.7% (95% CI 98.1 - 99.8). CONCLUSION: 85% of the patients with endometrial thickening had an abnormal hysteroscopy result, which latter were confirmed in 80% of the cases with biopsy. In a center with experience, a normal hysteroscopy result can make biopsy unnecessary. Potentially malignant hysteroscopys tend to be over diagnosed, making biopsy fundamental. All endometrial cancers were detected by hysteroscopy in our study.
