ABSTRACT

El síndrome de Herlyn-Werner Wünderlich, también llamado OHVIRA por sus siglas en inglés (obstructed hemivagina and ipsilateral renal anomaly), es una anomalía congénita mülleriana poco frecuente que se caracteriza por la asociación entre útero didelfo, hemivagina obstruida y agenesia renal ipsilateral. La presentación clínica más común es la masa abdominal secundaria a hematocolpos, dolor y dismenorrea. Se asocia a infertilidad, endometriosis, alteraciones menstruales y obstétricas. La ecografía es la técnica de elección para la evaluación inicial, mientras que la resonancia magnética sigue siendo el método más exacto para el diagnóstico. La septotomía vaginal es el tratamiento recomendado. Se describen 2 casos clínicos con el objetivo de destacar la importancia del diagnóstico temprano para evitar las posibles complicaciones futuras.


Herlyn-Werner-Wunderlich syndrome, also known as obstructed hemivagina and ipsilateral renal anomaly (OHVIRA), is a rare, congenital Müllerian duct anomaly characterized by the association of septate uterus, obstructed hemivagina, and ipsilateral renal agenesis. The most common clinical presentation is an abdominal mass secondary to hematocolpos, pain, and dysmenorrhea. It is associated with infertility, endometriosis, and menstrual and obstetric alterations. The ultrasound is the technique of choice for the initial assessment, while the magnetic resonance imaging remains the most accurate method for diagnosis. The resection of the vaginal septum is the recommended treatment. Here we describe 2 clinical cases to highlight the importance of an early diagnosis to prevent potential complications in the future.

ABSTRACT

Objetivo: Estudiar la relación que existe entre algunos factores predisponente a desarrollar endometriosis y síntomas más frecuentes que manifiestan las pacientes. Métodos: Estudio observacional longitudinal, retrospectivo y descriptivo, mediante la revisión de 455 historias tomadas 560 pacientes que acudieron a la consulta de endometriosis y realizando diagnóstico definitivo en el Hospital Universitario "Dr. Ángel Larralde" y consulta privada, en Venezuela, estado Carabobo, en el periodo de enero 2006 a mayo 2023. Resultados: El diagnóstico se realizó en un 47,1 % de las pacientes con edades entre 26 a 35 años. La menarquia se presentó entre los 8 y los 12 años (el 69 %). El 63 % no tenía embarazos. La dismenorrea primaria fue más frecuente en el 63,07 %. El dolor pélvico y dispareunia en el 48 %, los síntomas digestivos en el 21 %. La localización más frecuente fue en ovario (78,7 %). Conclusión: La endometriosis, enfermedad inflamatoria benigna, estrógeno dependiente, se caracteriza por presencia de glándulas y estroma endometrial ectópico, usualmente acompañados de fibrosis. Se manifiesta en el periodo reproductivo, su principal síntoma es el dolor. Se localiza con mayor frecuencia en la pelvis y de esta en los ovarios, en intestino, vejiga, hígado, pulmones, cerebro, pared abdominal y periné. No hay tratamiento para su cura, pero si para los síntomas y retardar su progreso. Su diagnóstico por su desarrollo multifactorial y manifestaciones clínicas en muchas oportunidades se realiza en forma tardía(AU)


Objective: To study the relationship that exists between some predisposing factors to develop endometriosis and the most frequent symptoms manifested by patients. Methods: Longitudinal, retrospective and descriptive observational study, through the review of 455 records taken from 560 patients who attended the endometriosis consultation and made a definitive diagnosis at the "Dr. Ángel Larralde" and private consultation, in Venezuela, Carabobo state, in the period from January 2006 to May 2023. Results: The diagnosis was made in 47.1% of the patients aged between 26 and 35 years. Menarche occurred between 8 and 12 years of age (69%). 63% did not have pregnancies. Primary dysmenorrhea was more frequent in 63.07%. Pelvic pain and dyspareunia in 48%, digestive symptoms in 21%. The most frequent location was in the ovary (78.7%). Conclusion: Endometriosis, a benign, estrogen-dependent inflammatory disease, is characterized by the presence of ectopic endometrial glands and stroma, usually accompanied by fibrosis. It manifests itself in the reproductive period, its main symptom is pain. It is located most frequently in the pelvis and from this in the ovaries, intestine, bladder, liver, lungs, brain, abdominal wall and perineum. There is no treatment to cure it, but there is treatment for the symptoms and slowing its progress. Its diagnosis due to its multifactorial development and clinical manifestations is often made late(AU)

ABSTRACT

SUMMARY: The study explores the relationship between chronic exposure to fine particulate matter (PM2.5), sourced from wood smoke, and the histological structure and endocrine function of the uterus in nulliparous adult rats. It assesses potential structural changes in the uterus that could impact reproductive health, viewing PM2.5 exposure as a possible risk factor. A controlled experiment was conducted in a city known for high air pollution levels, exposing rats to filtered and unfiltered air conditions, thus mimicking human PM2.5 exposure. Histological findings indicated a significant increase in collagen density and uterine wall thickness in PM2.5 exposed subjects, suggesting a reproductive function risk. However, no significant differences were observed in progesterone and estradiol hormone levels, pointing to the complex relationship between PM2.5 exposure and its endocrine impact, and emphasizing the need for further studies for a deeper understanding. This work highlights the importance of thoroughly investigating the long-term effects of PM2.5 pollution on reproductive health, underlining the significance of considering environmental exposure as a critical factor in reproductive health research.


El estudio explora la relación entre la exposición crónica a partículas finas (PM2,5), procedentes del humo de leña, y la estructura histológica y la función endocrina del útero en ratas adultas nulíparas. Evalúa posibles cambios estructurales en el útero que podrían afectar la salud reproductiva, considerando la exposición a PM2,5 como un posible factor de riesgo. Se llevó a cabo un experimento controlado en una ciudad conocida por sus altos niveles de contaminación del aire, exponiendo ratas a condiciones de aire filtrado y sin filtrar, imitando así la exposición humana a PM2,5. Los hallazgos histológicos indicaron un aumento significativo en la densidad del colágeno y el grosor de la pared uterina en sujetos expuestos a PM2,5, lo que sugiere un riesgo para la función reproductiva. Sin embargo, no se observaron diferencias significativas en los niveles de las hormonas progesterona y estradiol, lo que apunta a la compleja relación entre la exposición a PM2,5 y su impacto endocrino, y enfatiza la necesidad de realizar más estudios para una comprensión más profunda. Este trabajo destaca la importancia de investigar a fondo los efectos a largo plazo de la contaminación por PM2,5 en la salud reproductiva, subrayando la importancia de considerar la exposición ambiental como un factor crítico en la investigación de la salud reproductiva.

ABSTRACT

Objective: To investigate the clinical characteristics, treatments and fertility recovery of rudimentary horn pregnancy (RHP). Methods: The clinical data of 12 cases with RHP diagnosed and treated in Peking University Third Hospital from January 1, 2010 to December 31, 2022 were retrospectively analyzed. Clinical informations, diagnosis and treatments of RHP and the pregnancy status after surgery were analyzed. Results: The median age of 12 RHP patients was 29 years (range: 24-37 years). Eight cases of pregnancy in residual horn of uterus occurred in type Ⅰ residual horn of uterus, 4 cases occurred in type Ⅱ residual horn of uterus; among which 5 cases were misdiagnosed by ultrasound before surgery. All patients underwent excision of residual horn of uterus and affected salpingectomy. After surgery, 9 patients expected future pregnancy, and 3 cases of natural pregnancy, 2 cases of successful pregnancy through assisted reproductive technology. Four pregnancies resulted in live birth with cesarean section, and 1 case resulted in spontaneous abortion during the first trimester of pregnancy. No uterine rupture or ectopic pregnancy occurred in subsequent pregnancies. Conclusions: Ultrasonography could aid early diagnosis of RHP while misdiagnosis occurred in certain cases. Thus, a comprehensive judgment and decision ought to be made based on medical history, physical examination and assisted examination. Surgical exploration is necessary for diagnosis and treatment of RHP. For infertile patients, assisted reproductive technology should be applied when necessary. Caution to prevent the occurrence of pregnancy complications such as uterine rupture, and application of cesarean section to terminate pregnancy are recommended.

ABSTRACT

Este trabalho tem o objetivo de analisar as concepções de maternidade para mulheres inférteis de diferentes níveis socioeconômicos que estão em tratamento de reprodução assistida. Trata-se de um estudo qualitativo, descritivo, que utilizou como instrumento uma entrevista semiestruturada e contemplou temas como o significado de família, desejo/expectativas sobre filho e gestação e expectativas sobre a maternidade. Participaram da pesquisa 48 mulheres inférteis acima de 35 anos que usam tecnologias de reprodução assistida de alta complexidade em instituições privada e pública. Os dados foram tratados pela análise de conteúdo em que emergiram os temas: representações sociais da família; representações sociais da maternidade; expectativas com a gestação e os modelos maternos; e o filho imaginado. As participantes representaram a família de forma positiva, como um sistema de suporte, de fundação e origem de amor, configurando-a como um laço social. Por outro lado, as concepções de família com base na consanguinidade também estiveram presentes, representando a família pela perpetuação da espécie e pela importância do laço biológico. A maternidade foi marcada por significativa idealização, sendo vista como um papel gratificante e de realização da feminilidade. O peso da cobrança social para procriar também foi sentido como um dever a cumprir e que, na impossibilidade de se realizar, gera sentimentos de inferioridade, menos-valia, impotência e inadequação perante a sociedade, o que reforça o estigma da infertilidade. Tais resultados apontam a importância de reflexões sobre o papel da mulher na nossa cultura, visto que a maternidade é ainda utilizada como medida para o sucesso ou fracasso feminino. Faz-se necessário também refletir sobre a possibilidade da maior inserção do trabalho psicológico na reprodução assistida, visto a carga emocional e social envolvidas nesse processo.(AU)


This study aimed to analyze the conceptions of motherhood for infertile women from different socioeconomic levels who are undergoing assisted reproduction treatment. This is a qualitative and descriptive study that used a semi-structured interview as an instrument and included topics such as the meaning of family and desires/expectations about the child, pregnancy, and motherhood. A total of 48 infertile women over 35 years of ages using high-complexity assisted reproductive technologies in private and public institutions participated in this research. The data were treated by content analysis in which the following themes emerged: family social representations; social representations of motherhood; expectations with pregnancy and maternal models; and the imagined son. Participants represented the family in a positive way as a support system and the foundation and origin of love, embracing the family as a social bond. On the other hand, the family concepts based on inbreeding were also present, representing the family by perpetuation of the species and the importance of biological bonds. Motherhood was marked by significant idealization, being seen as a gratifying role and the fulfillment of femininity. The weight of the social demand to procreate was also felt as a duty to be fulfilled that, in the impossibility of carrying it out, generates feelings of inferiority, worthlessness, impotence, and inadequacy toward society, which reinforce the stigma of infertility. Results point to the necessary reflections on the role of women and our culture since Motherhood is still used as a measure of female success or failure. They also point to a reflection on the possibility of greater inclusion of psychological work in assisted reproduction given the emotional and social burden involved in this process.(AU)

Se trata de un estudio cualitativo, descriptivo, que utilizó como instrumento una entrevista semiestructurada e incluyó temas como el sentido de la familia, deseos/expectativas sobre el hijo y el embarazo y expectativas sobre la maternidad. Participaron en la investigación un total de 48 mujeres infértiles, mayores de 35 años, usuarias de tecnologías de reproducción asistida de alta complejidad en instituciones públicas y privadas. Los datos se sometieron a análisis de contenido del cual surgieron los temas: representaciones sociales familiares; representaciones sociales de la maternidad; expectativas con el embarazo y modelos maternos; hijo imaginado. Las participantes representaron a la familia de manera positiva, como sistema de apoyo, fundamento y origen del amor, configurándola como vínculo social. Por otro lado, también estuvieron presentes las concepciones familiares basadas en la consanguinidad, representando a la familia para la perpetuación de la especie y la importancia del vínculo biológico. La maternidad estuvo marcada por una importante idealización, vista como un rol gratificante y de realización de la feminidad. También se sintió el peso de la demanda social de procrear como un deber que cumplir y que, ante la imposibilidad de realizarlo, genera sentimientos de inferioridad, desvalorización, impotencia e inadecuación en la sociedad, lo que refuerza el estigma de la infertilidad. Por tanto, son necesarias reflexiones sobre el papel de la mujer en nuestra cultura, ya que la maternidad se sigue utilizando como medida del éxito o fracaso femenino. También se reflexiona sobre la posibilidad de una mayor inclusión del trabajo psicológico en la reproducción asistida dada la carga emocional y social que implica este proceso.(AU)

ABSTRACT

El síndrome de hemivagina obstruida y anomalía renal ipsilateral (OHVIRA) es producido por una alteración en el desarrollo de los conductos de Müller y Wolff en la vida fetal. El síndrome es poco frecuente, se reporta una prevalencia de 1/2.000 a 1/28.000 casos. La endometriosis se presenta en un 19% de los casos complicando esta patología. El tratamiento del síndrome OHVIRA consiste en resecar el tabique vaginal drenando el hematocolpos. Hasta el momento no existe un consenso en recomendar la realización de una laparoscopia diagnóstica. El objetivo de este estudio es reportar la eventual importancia de la laparoscopia diagnóstica/terapéutica como parte del manejo del síndrome OHVIRA.


Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome is caused by a defect in the development of Müllerian and Wolffian ducts at fetal life. The syndrome is uncommon, with a reported prevalence of 1/2,000 to 1/28,000 cases. Endometriosis is present in 19% of cases complicating this pathology. Treatment of OHVIRA syndrome consists in resecting the vaginal septum and draining the hematocolpos. Until now there isnt an agreement on recommending diagnostic laparoscopy as part of the treatment. The aim of this study is to report the importance of diagnostic/therapeutic laparoscopy in the management of OHVIRA syndrome.

ABSTRACT

Malformações müllerianas correspondem a variações anatômicas do trato repro- dutor feminino. Comumente assintomáticas, o diagnóstico e a verdadeira incidên- cia são difíceis de determinar. A síndrome de Herlyn-Werner-Wunderlich, clas- sicamente descrita pela tríade útero didelfo, hemivagina cega e agenesia renal ipsilateral também pode ter variações diferentes. Em virtude da mesma origem embrionária dos tratos genital e urinário, anomalias renais devem ser investigadas nesses casos, sendo a mais comum a agenesia renal. Este artigo relata o caso de uma paciente de 18 anos, do sexo feminino, com história de piocolpo por cinco anos. Em propedêutica complementar, foi identificado útero com septação com- pleta associado a hemissepto de terço superior de vagina, formação de piocolpo e agenesia renal à direita. Apesar de não ser a definição clássica, o quadro está incluído nos casos de síndrome de Herlyn-Werner-Wunderlich.


Mullerian malformations correspond to anatomical variations of the female repro- ductive tract. Commonly asymptomatic, the diagnosis and true incidence are difficult to determine. The Herlyn-Werner-Wunderlich syndrome, classically described by the triad: uterus didelphus, blind hemivagina and ipsilateral renal agenesis, can also have different variations. Due to the same embryonic origin of the genital and urinary tracts, renal anomalies must be investigated in these cases, the most common being renal agenesis. This article reports the case of an 18-year-old female patient with a 5-year history of pyocolpus. In complementary exams, a uterus with complete septa- tion was identified, associated with a hemiseptum in the upper third of the vagina, formation of pyocolpus and renal agenesis on the right side. Despite not being the classic definition, it is included in the cases of Herlyn-Werner-Wunderlich syndrome.

ABSTRACT

Las malformaciones müllerianas (MM) son un grupo de anomalías estructurales originadas por fallas de desarrollo de los conductos paramesonéfricos o de Müller durante las primeras 16 semanas de gestación. Un oportuno diagnóstico y una correcta clasificación permiten ofrecer el mejor manejo y diferenciar aquellas pacientes que requieren tratamiento quirúrgico. Se realizó una revisión de la literatura sobre MM en las bases de datos Epistemonikos, SciELO, Cochrane y PubMed. Se rescataron todas las pacientes ingresadas con diagnóstico de MM. En el año 2021, la American Society of Reproductive Medicine publicó un consenso en el que se estandarizó la nomenclatura, se amplió el espectro y se simplificó la clasificación. La clínica es variada, e incluye pacientes asintomáticas cuyo diagnóstico es un hallazgo por imágenes. Los mejores estudios imagenológicos son la resonancia magnética (RM) y la ultrasonografía 3D, dejando la histeroscopia y la laparoscopia (método de referencia) como procedimiento diagnóstico-terapéutico. Se presentan casos clínicos desarrollados durante el primer trimestre de 2022. Recomendamos la utilización sistemática de la RM para el diagnóstico de anomalías complejas u obstructivas del aparato genital. El tratamiento de estas patologías debe ser realizado por ginecólogos endoscopistas expertos, e incluye tratamiento médico y quirúrgico, el cual debe ser enfocado en cada paciente dependiendo del tipo de MM y de los deseos de fertilidad.


Müllerian malformations (MM) are a group of structural anomalies caused by developmental failure of the paramesonephric or Müllerian ducts during the first 16 weeks of gestation. Timely diagnosis and classification allow us to offer the best management and to differentiate those patients who require surgical treatment. Literature review on MM in Epistemonikos, SciELO, Cochrane and PubMed databases. All patients admitted with a diagnosis of MM were rescued. In 2021, the American Society of Reproductive Medicine publishes a consensus where it standardizes the nomenclature, broadens the spectrum, and simplifies the classification. The clinical picture is varied and includes asymptomatic patients whose diagnosis is an imaging finding. The best imaging studies are magnetic resonance imaging (MRI) and 3D ultrasonography, leaving hysteroscopy and laparoscopy (gold standard) as diagnostic therapeutic. Clinical cases developed during the first trimester 2022 are presented. We recommend the routine use of MRI for the diagnosis of complex and/or obstructive anomalies of the genital tract. The treatment of these pathologies should be performed by expert endoscopic gynecologists and include medical and surgical treatment, which should be focused on each patient, depending on the type of MM and fertility desires.

ABSTRACT

O sangramento uterino anormal é diagnóstico sindrômico comum no consultório do ginecologista e pode comprometer substancialmente a qualidade de vida. O objetivo no diagnóstico de sangramento uterino anormal é distinguir pacientes com causas estruturais (anatômicas), como pólipo, adenomiose, leiomioma, malignidade e hiperplasia, de pacientes que apresentam anatomia normal, nas quais o sangramento pode ser devido a alteração dos mecanismos de coagulação, distúrbios ovulatórios, distúrbios primários do endométrio, iatrogenia, ou ter outra causa não classificada. O diagnóstico se inicia a partir de anamnese detalhada e exame físico geral e ginecológico completos, seguidos da solicitação de exames complementares (laboratoriais e de imagem), conforme indicado. O exame de imagem de primeira linha para identificação das causas estruturais inclui a ultrassonografia pélvica. Histerossonografia, histeroscopia, ressonância magnética e amostragem endometrial para exame de anatomia patológica são opções que podem ser incluídas no diagnóstico a depender da necessidade. O objetivo deste artigo é apresentar a relevância dos exames de imagem na investigação das causas de sangramento uterino anormal.


Abnormal uterine bleeding is one of the commonest presenting complaints encountered in a gynecologist's office and may substantially affect quality of life. The aim in the diagnosis of abnormal uterine bleeding is to distinguish women with anatomic causes such as polyp, adenomyosis, leiomyoma, malignancy and hyperplasia from women with normal anatomy where the cause may be coagulopathy, ovulatory disorders, endometrial, iatrogenic and not otherwise classified. Diagnosis begins with a thorough history and physical examination followed by appropriate laboratory and imaging tests as indicated. The primary imaging test for the identification of anatomic causes include ultrasonography. Saline infusion sonohysterography, magnetic resonance, hysteroscopy, endometrial sampling are options that can be included in the diagnosis depending on the need. The aim of this article is to present the relevance of imaging exams in the investigation of the causes of abnormal uterine bleeding.

ABSTRACT

O presente estudo tem como objetivo relatar o caso de uma paciente com malformação arteriovenosa uterina, efetivamente tratada com embolização seletiva e com fertilidade preservada. A malformação arteriovenosa uterina é uma alteração vascular rara até então pouco descrita na literatura. A paciente do sexo feminino apresentou quadro de sangramento uterino anormal, com início 30 dias após um abortamento, sem realização de curetagem, de uma gestação resultante de fertilização in vitro. Foram, então, realizados exames de imagem, que levaram ao diagnóstico de malformação arteriovenosa uterina. O tratamento de escolha foi a embolização arterial seletiva, com resolução do caso. Após sete meses, nova fertilização in vitro foi realizada, encontrando-se na 36a semana de gestação. São necessários mais estudos sobre essa malformação a fim de que sejam estabelecidos os métodos mais eficazes para o manejo de casos futuros, especialmente quando há desejo de gestar.


The present study aims to report the case of a patient with uterine arteriovenous malformation, effectively treated with selective embolization and with preserved fertility. Uterine arteriovenous malformation is a rare vascular disorder that has so far been rarely described in the literature. Female patient presented with abnormal uterine bleeding, starting 30 days after an abortion without subsequent curettage, of a pregnancy resulting from in vitro fertilization. Imaging tests were then performed that led to the diagnosis of uterine arteriovenous malformation. The treatment of choice was selective arterial embolization, with successful results. After seven months, a new in vitro fertilization was performed, being in the 36th week of pregnancy. Further studies on this pathology are needed in order to establish the most effective methods for the management of future cases, especially when there is a desire to become pregnant.

ABSTRACT

SUMMARY: Estradiol and progesterone receptors play an essential role in the changes occurring in the uterus during the estrus cycle in dogs (Canis lupus familiaris). In order to investigate the potential effect of progestational agent medroxyprogesterone acetate (MPA) when is used during anestrus on the expression of estradiol receptors [ER], progesterone receptors [PR] and nuclear protein Ki67, we evaluated uterine tissue immunohistochemically. Uteri were grouped as nulliparous (control, n=11), multiparous (n=11) and treated with MPA (n=11; nulliparous with two treatments; 5mg/kg; i.m.). The amount and location of PR, ER and Ki67 were studied on the epithelial surface, apical and basal regions of the endometrium and myometrium using immunohistochemical techniques with a spectral confocal microscope and analyzed by ANOVA. Differences in ER were observed between the multiparous and MPA-treated groups in the apical region of the endometrium (p=0.0022). Differences in cell proliferation were detected between the nulliparous and multiparous groups (p=0.0037) and nulliparous and MPA-treated groups (p=0.0003) in the basal region of the endometrium. In conclusion, two doses of MPA (5mg/kg; i.m.) do not have a significant effect on the expression of ER and PR; however, they inhibit cell proliferation in the basal region of the endometrium, which includes the stroma, subepithelial cell layer, compact layer, and spongy layer. The clinical and long-term effect of this treatment should be evaluated in subsequent studies.


Los receptores de estradiol y progesterona juegan un rol fundamental en los cambios que se producen en el útero durante el ciclo estral de las perras (Canis lupus familiaris). El objetivo de este estudio fue evaluar las expresiones de ER-a y PR en el útero y la proliferación de células endometriales detectando la expresión nuclear de la proteína Ki67 en perras expuestas a la progestina sintética MPA y compararlas con perras nulíparas y multíparas expuestas a progesterona luteal. Úteros fueron agrupados como nulíparas (control, n=11), multíparas (n=11) y tratadas con MPA (n=11; nulíparas con dos tratamientos; 5 mg/kg; i.m.). La expresión de PR, ER-a y Ki67 fue evaluada en la regiones apicales y basales del endometrio y miometrio con un microscopio confocal espectral. Se observó diferencias en ER-a entre los grupos multíparas y tratados con MPA en la región apical del endometrio (p=0,0022). Se detectaron diferencias en la proliferación celular entre los grupos de nulíparas y multíparas (p=0,0037) y los grupos de nulíparas y tratados con MPA (p=0,0003) en la región basal del endometrio. En conclusión, dos dosis de MPA (5mg/kg; i.m.) no tienen un efecto significativo sobre la expresión de ER y PR; sin embargo, inhiben la proliferación celular en la región basal del endometrio, el cual incluye a estroma, capa de células subepiteliales, estratos compacto y esponjoso. El efecto clínico a largo plazo de este tratamiento debe ser evaluado en estudios posteriores.

ABSTRACT

Abstract Isthmocele is a discontinuation of the myometrium at the uterine scar site in a patient with a previous cesarian section (CS). The cause of isthmocele appears to be multifactorial. Poor surgical technique, low incision location, uterine retroflection, obesity, smoking, inadequate healing of scars, and maternal age are possible related factors. Most patients with this condition are asymptomatic. However, women can present with postmenstrual bleeding, pelvic pain, subfertility, dysmenorrhea, infertility, and scar abscess. Brazil has one of the world s highest cesarean section rates. One of the consequences of the rising rate of CS is the isthmocele, an emerging female health problem. Here we report a case of mucinous cystadenoma arising in a uterine isthmocele, a complication, as far as we could investigate, not yet described in the literature.


Resumo Istmocele é a descontinuidade do miométrio no local da cicatriz uterina em paciente com cesariana anterior. A causa da istmocele parece ser multifatorial. Má técnica cirúrgica, baixa localização da incisão, retroflexão uterina, obesidade, tabagismo, cicatrização inadequada de cicatrizes e idade materna são possíveis fatores relacionados. A maioria dos pacientes com esta condição é assintomática. No entanto, as mulheres podem apresentar sangramento pós-menstrual, dor pélvica, subfertilidade, dismenorreia, infertilidade e abscesso cicatricial. O Brasil tem uma das maiores taxas de cesariana do mundo. Uma das consequências da taxa crescente de cesarianas é a istmocele, um problema emergente de saúde feminina. Aqui relatamos um caso de cistoadenoma mucinoso originado em uma istmocele uterina, uma complicação ainda não descrita, até onde pudemos investigar.

ABSTRACT

Abstract Objective: To determine the efficacy of Uterine Artery Embolization in patients with bleeding acquired uterine arteriovenous malformations (AVMs). Methods: A prospective review of all patients who underwent Uterine Artery Embolization at our institution between July 2015 and April 2022 was performed. 225 patients were diagnosed with a uterine vascular malformation on doppler and corresponding MRI imaging. All patients underwent transcatheter embolization of the uterine arteries. Embolic agents in the 375 procedures included Histoacryl glue only (n = 326), polyvinyl alcohol (PVA) particles and Histoacryl glue (n = 29), PVA particles (n = 5), Gelfoam (n = 5), coils (n = 4), PVA particles and coils (n = 3), Histoacryl glue and Gelfoam (n = 2), and Histoacryl glue and coils (n = 1). Results: A total of 375 embolization procedures were performed in 225 patients. 90 patients required repeat embolization for recurrence of bleeding. The technical success rate of embolization was 100%. The clinical success rate was 92%: bleeding was controlled in 222 of 225 patients and three patients underwent a hysterectomy. 60 of the 225 patients had uneventful intrauterine pregnancies carried to term. The 210 patients who underwent successful embolization had no recurrence of bleeding at a median follow-up of 53 months (range, 5-122 months) after treatment. 15 patients were eventually lost to follow-up. One minor complication (0.4%) of non-flow-limiting dissection of the internal iliac artery occurred. Conclusion: Uterine Artery Embolization is a safe, effective, minimally invasive method to treat uterine AVMs with long-term efficacy, which can provide the preservation of fertility.

ABSTRACT

O parto cesáreo (PC) é o procedimento cirúrgico mais comumente realizado nos Estados Unidos (mais de 1 milhão de cirurgias por ano) e um dos procedimentos mais realizados em todo o mundo.(1) Embora o PC seja um procedimento potencialmente salvador de vidas, quando corretamente indicado, sua frequência aumentou constantemente nas últimas décadas (atualmente 21,1% globalmente, variando de 5%, na África Subsaariana, a 42,8%, na América Latina e no Caribe). Além disso, estudos demonstram tendência continuada de aumento (projeção para 2030: 28,5% globalmente, variando de 7,1%, na África Subsaariana, a 63,4%, no leste da Ásia).(2) República Dominicana, Brasil, Chipre, Egito e Turquia são os líderes mundiais, com taxas de PC variando de 58,1% a 50,8%, respectivamente, o que aponta para uma tendência preocupante de medicalização do parto e indicação excessiva do PC.(2) Outros procedimentos cirúrgicos como dilatação, curetagem, miomectomia e histeroscopia cirúrgica são menos frequentes que o PC. Ainda assim, devido à tendência de maior idade materna, o número de gestantes previamente submetidas a esses procedimentos também tende a aumentar. Esses dados apontam para um número crescente de gestações em úteros manipulados cirurgicamente Gestantes com cicatrizes uterinas prévias correm risco de aumento da morbimortalidade. Complicações como placenta prévia, rotura uterina espontânea, deiscência uterina (com ou sem intrusão placentária), gestação em cicatriz de cesariana (GCC) e distúrbios do espectro do acretismo placentário (EAP) estão associadas a sangramento uterino potencialmente fatal, lesões extrauterinas e parto pré-termo

ABSTRACT

Objetivo: Identificar o impacto da histerectomia para patologias benignas sobre a sexualidade feminina. Métodos: Revisão de literatura com busca na plataforma PubMed, sendo selecionados 23 artigos em português e inglês publicados entre 2016 e 2021. Resultados: Foi descrita, majoritariamente, melhora na função sexual após histerectomia, semelhante às abordagens totais ou supracervicais e independentemente da via de acesso cirúrgico, apesar de impacto ligeiramente menor com a via laparoscópica. Na laparoscopia, houve melhor desfecho sexual no fechamento da cúpula vaginal, quando comparado ao fechamento via vaginal. Ademais, a ooforectomia concomitante apresentou resultados conflitantes e inconclusivos. Conclusão: A histerectomia afeta positivamente a saúde sexual feminina e aspectos técnicos podem interferir na função sexual, porém os dados são limitados. Devido à importância do tema, necessitam-se de mais estudos com metodologias padronizadas para possibilitar análises mais detalhadas.


Objective: To identify the impact of hysterectomy for benign pathologies on female sexuality. Methods: Literature review with search on PubMed platform, being selected 23 articles in Portuguese and English published between 2016 and 2021. Results: Improvement in sexual function after hysterectomy was mostly described, being similar in total or supracervical approaches and independent of the surgical access route, although it had slightly lower impact when laparoscopic. In the laparoscopic approach, there was better sexual outcome in the vaginal dome closure when compared to vaginal closure. In addition, concomitant oophorectomy showed conflicting and inconclusive results. Conclusion: Hysterectomy positively affects female sexual health and technical aspects may interfere with sexual function, but data are limited. Due to the importance of the theme, more studies with standardized methodologies are needed to enable more detailed analyses.

ABSTRACT

Abdominal pregnancy is defined as one that occurs outside of the uterus and fallopian tubes in the abdominal cavity. We present the case of a 30-year-old Peruvian female patient from Lima with a surgical history of exploratory laparotomy due to tubal ectopic pregnancy and appendectomy without further relevant personal or family histories. She attended the emergency room of a social security hospital in Peru with a referral from a district hospital and a diagnosis of abdominal pregnancy at 14 weeks of gestational age without previous prenatal controls. Symptomatology at hospital admission was colic-type abdominal pain in the hypogastrium without vaginal bleeding, fluid loss or fever. During hospitalization, she underwent an exploratory laparotomy with embolization of the uterine artery, left salpingectomy, and removal of the abdominal ectopic pregnancy. The evolution was favorable after the surgery, and she was discharged. Without further complications, she continues her controls at the obstetrics and gynecology outpatient service without complications.


El embarazo abdominal es aquel embarazo que ocurre fuera del útero y las trompas de Falopio en la cavidad abdominal. Presentamos el caso de una paciente peruana de 30 años proveniente de la ciudad de Lima, con antecedentes quirúrgicos de laparotomía exploradora por embarazo ectópico tubárico y apendicectomía, sin otras patologías ni antecedentes familiares de importancia. La paciente acude al servicio de urgencias de un hospital del seguro social en Perú derivada de un hospital distrital con diagnóstico de embarazo abdominal a las 14 semanas de edad gestacional, sin controles prenatales previos. La sintomatología al ingreso hospitalario fue dolor abdominal de tipo cólico a nivel del hipogastrio, sin sangrado vaginal, pérdida de líquidos o fiebre. Durante su hospitalización se le realizó una laparotomía exploratoria con embolización de la arteria uterina, salpingectomía izquierda y extracción del embarazo abdominal. La evolución fue favorable tras la intervención quirúrgica, siendo dada de alta. Actualmente continúa sus controles en el servicio de consulta externa del servicio de ginecología y obstetricia sin complicaciones.

ABSTRACT

OBJECTIVE@#To observe the effects of electroacupuncture (EA) on NLRP3 inflammasome and its downstream protein gastermin D (GSDMD) in rats with primary dysmenorrhea (PDM), and to explore the potential mechanism of EA on the treatment of PDM.@*METHODS@#Forty healthy female SD rats without pregnancy were randomly divided into a control group, a model group, an EA group and an ibuprofen group, 10 rats in each group. PDM model was prepared by injection of estradiol benzoate and oxytocin. Except the control group, the rats in each group were subcutaneously injected with estradiol benzoate for 10 days, and oxytocin was injected on the 11th day. The rats in the EA group were intervened with EA (dense wave, frequency of 50 Hz) at "Guanyuan" (CV 4) and "Sanyinjiao" (SP 6) at the same time of modeling, once a day, 20 min each time, for 10 consecutive days. The rats in the ibuprofen group were treated with 0.8 mL of ibuprofen by gavage (concentration of ibuprofen solution was 1.25 mg/mL) for 10 consecutive days. After modeling, the writhing reaction was observed. After intervention, the HE staining method was used to observe the histological morphology of uterus and evaluate the pathological damage score of uterus; ELISA method was used to detect the serum levels of prostaglandin E2 (PGE2) and prostaglandin F2α (PGF2α); Western blot method was used to detect the protein expression of NLRP3, apoptosis related spot like protein (ASC), caspase-1, GSDMD, GSDMD-N and inflammatory factors (interleukin [IL]-1β, IL-18) in uterine tissue.@*RESULTS@#In the model group, a large number of vacuolar degeneration and death of endometrial epithelial cells, spiral arterioles congestion in lamina propria and neutrophil infiltration were observed. In the EA group, there was a small amount of vacuolar degeneration and death of endometrial epithelial cells, a small amount of spiral arterioles congestion in the lamina propria, and a small amount of neutrophils infiltration. In the ibuprofen group, there was very small number of degeneration and death of endometrial epithelial cells, and no obvious arterial congestion was found in lamina propria, and neutrophil infiltration was occasionally seen. Compared with the control group, in the model group the number of writhing was increased (P<0.01), the writhing reaction score and serum level of PGF2α and PGF2α/PGE2 value were increased (P<0.01), the level of PGE2 was decreased (P<0.01). Compared with the model group, in the EA group and the ibuprofen group the number of writhing were decreased (P<0.05), the latency of writhing was prolonged (P<0.01), the writhing reaction scores and serum levels of PGF2α and PGF2α/PGE2 values were decreased (P<0.05, P<0.01), the levels of PGE2 were increased (P<0.01). Compared with the control group, the protein expression of NLRP3, ASC, caspase-1, GSDMD, GSDMD-N, IL-1β and IL-18 in the uterine tissues of rats was increased in the model group (P<0.01). Compared with the model group, the protein expression of NLRP3, ASC, caspase-1, GSDMD, GSDMD-N, IL-1β and IL-18 in the uterine tissues of rats was decreased in the EA group and the ibuprofen group (P<0.01, P<0.05). There was no significant difference between the EA group and the ibuprofen group in the above indexes (P>0.05).@*CONCLUSION@#EA could alleviate pain and uterine tissue injury in rats with PDM. The mechanism may be related to the inhibition of the activation of NLRP3 inflammasome in rat uterine tissues, thereby inhibiting pyroptosis and its inflammatory factors release.

ABSTRACT

OBJECTIVES@#To study the value of basal luteinizing hormone (LH) level combined with uterine volume measurement in the early diagnosis of central precocious puberty (CPP) in girls with different Tanner stages.@*METHODS@#A retrospective analysis was performed on the girls who presented with breast development before the age of 8 years and attended the Third Affiliated Hospital of Zhengzhou University from January 2017 to September 2022. According to the results of gonadotropin-releasing hormone (GnRH) agonist test, the girls with peak LH ≥5.0 IU/L and peak LH/follicle stimulating hormone ≥0.6 were enrolled as the positive group, and the other girls were enrolled as the negative group. The two groups were compared in terms of the basal LH level and uterine volume. The receiver operating characteristic (ROC) curve was used to analyze their value in the early diagnosis of CPP.@*RESULTS@#For the girls with Tanner B2 and B3 stages, the positive group had significantly higher basal LH level and uterine volume than the negative group (P<0.05). The basal LH level had an optimal cut-off value of 0.325 IU/L and 0.505 IU/L respectively in the diagnosis of Tanner stage B2/B3 CPP, while uterine volume had an optimal cut-off value of 1.639 mL and 2.158 mL respectively. Basal LH level combined with uterine volume measurement had a significantly larger area under the ROC curve than uterine volume measurement alone (P<0.001), but with no significant difference compared with that of basal LH level measurement alone (P>0.05).@*CONCLUSIONS@#Basal LH level combined with uterine volume measurement is valuable in the early diagnosis of CPP in girls with different Tanner stages, which provides a basis and guiding significance for clinical diagnosis of CPP.

ABSTRACT

Objective@#To determine whether bisphenol S (BPS), a common substitute for bisphenol A (BPA), induces cell proliferation and migration in human endometrial epithelial cells (Ishikawa) and adult mouse uterine tissues.@*Methodology@#Human endometrial Ishikawa cells were exposed to low doses of BPS (1 nM and 100 nM) for 72 hours. Cell proliferation was assessed through the viability assays MTT and CellTiter-Glo®. Wound healing assays were also used to evaluate the migration potential of the cell line. The expression of genes related to proliferation and migration was also determined. Similarly, adult mice were exposed to BPS at a dose of 30 mg/kg body weight/day for 21 days, after which, the uterus was sent for histopathologic assessment.@*Results@#BPS increased cell number and stimulated migration in Ishikawa cells, in association with the upregulation of estrogen receptor beta (ESR2) and vimentin (VIM). In addition, mice exposed to BPS showed a significantly higher mean number of endometrial glands within the endometrium.@*Conclusion@#Overall, in vitro and in vivo results obtained in this study showed that BPS could significantly promote endometrial epithelial cell proliferation and migration, a phenotype also observed with BPA exposure. Hence, the use of BPS in BPA-free products must be reassessed, as it may pose adverse reproductive health effects to humans.

ABSTRACT

This study aimed to investigate the relationship between coagulating cold and blood stasis syndrome and glycolysis, and observe the intervention effect of Liangfang Wenjing Decoction(LFWJD) on the expression of key glycolytic enzymes in the uterus and ovaries of rats with coagulating cold and blood stasis. The rat model of coagulating cold and blood stasis syndrome was established by ice-water bath. After modeling, the quantitative scoring of symptoms were performed, and according to the scoring results, the rats were randomly divided into a model group and LFWJD low-, medium-and high-dose groups(4.7, 9.4, 18.8 g·kg~(-1)·d~(-1)), with 10 in each group. Another 10 rats were selected as the blank group. After 4 weeks of continuous administration by gavage, the quantitative scoring of symptoms was repeated. Laser speckle flowgraphy was used to detect the changes of microcirculation in the ears and uterus of rats in each group. Hematoxylin-eosin(HE) staining was used to observe the pathological morphology of uterus and ovaries of rats in each group. The mRNA and protein expressions of pyruvate dehydrogenase kinase 1(PDK1), hexokinase 2(HK2) and lactate dehydrogenase A(LDHA) in the uterus and ovaries of rats were examined by real-time quantitative polymerase chain reaction(RT-qPCR) and Western blot, respectively. The rats in the model group showed signs of coagulating cold and blood stasis syndrome, such as curl-up, less movement, thickened veins under the tongue, and reduced blood perfusion in the microcirculation of the ears and uterus, and HE staining revealed a thinning of the endometrium with disorganized arrangement of epithelial cells and a decrease in the number of ovarian follicles. Compared with the model group, the treatment groups had alleviated coagulating cold and blood stasis, which was manifested as red tongue, reduced nail swelling, no blood stasis at the tail end as well as increased blood perfusion of the microcirculation in the ears and uterus(P<0.05 or P<0.01). Among the groups, the LFWJD medium-and high-dose groups had the most significant improvement in coagulating cold and blood stasis, with neatly arranged columnar epithelial cells in uterus, and the number of ovarian follicles was higher than that in the model group, especially mature follicles. The mRNA and protein expressions of PDK1, HK2, LDHA in uterus and ovaries were up-regulated in the model group(P<0.05 or P<0.01), while down-regulated in LFWJD medium-and high-dose groups(P<0.05 or P<0.01). The LFWJD low-dose group presented a decrease in the mRNA expressions of PDK1, HK2 and LDHA in uterus and ovaries as well as in the protein expressions of HK2 and LDHA in uterus and HK2 and PDK1 in ovaries(P<0.05 or P<0.01). The therapeutic mechanism of LFWJD against coagulating cold and blood stasis syndrome is related to the down-regulation of key glycolytic enzymes PDK1, HK2 and LDHA, and the inhibition of glycolytic activities in uterus and ovaries.
