ABSTRACT

Abstract Objective Currently, there are up to three different classifications for diagnosing septate uterus. The interobserver agreement among them has been poorly assessed. To assess the interobserver agreement of nonexpert sonographers for classifying septate uterus using the European Society of Human Reproduction and Embryology/European Society for Gynaecological Endoscopy (ESHRE/ESGE), American Society for Reproductive Medicine (ASRM), and Congenital Uterine Malformations by Experts (CUME) classifications. Methods A total of 50 three-dimensional (3D) volumes of a nonconsecutive series of women with suspected uterine malformation were used. Two nonexpert examiners evaluated a single 3D volume of the uterus of each woman, blinded to each other. The following measurements were performed: indentation depth, indentation angle, uterine fundal wall thickness, external fundal indentation, and indentation-to-wall-thickness (I:WT) ratio. Each observer had to assign a diagnosis in each case, according to the three classification systems (ESHRE/ESGE, ASRM, and CUME). The interobserver agreement regarding the ESHRE/ESGE, ASRM, and CUME classifications was assessed using the Cohen weighted kappa index (k). Agreement regarding the three classifications (ASRM versus ESHRE/ESGE, ASRM versus CUME, ESHRE/ESGE versus CUME) was also assessed. Results The interobserver agreement between the 2 nonexpert examiners was good for the ESHRE/ESGE (k = 0.74; 95% confidence interval [CI]: 0.55-0.92) and very good for the ASRM and CUME classification systems (k = 0.95; 95%CI: 0.86-1.00; and k = 0.91; 95%CI: 0.79-1.00, respectively). Agreement between the ESHRE/ESGE and ASRM classifications was moderate for both examiners. Agreement between the ESHRE/ESGE and CUME classifications was moderate for examiner 1 and good for examiner 2. Agreement between the ASRM and CUME classifications was good for both examiners. Conclusion The three classifications have good (ESHRE/ESGE) or very good (ASRM and CUME) interobserver agreement. Agreement between the ASRM and CUME classifications was higher than that for the ESHRE/ESGE and ASRM and ESHRE/ESGE and CUME classifications.


Resumo Objetivo Atualmente, existem até três classificações diferentes para o diagnóstico de útero septado. A concordância interobservador entre eles tem sido pouco avaliada. Avaliar a concordância interobservador de ecografistas não especialistas para classificar úteros septados usando as classificações European Society of Human Reproduction and Embryology/European Society for Gynaecological Endoscopy (ESHRE/ESGE, na sigla em inglês), American Society for Reproductive Medicine (ASRM, na sigla em inglês) e Congenital Uterine Malformations by Experts (CUME, na sigla em inglês). Métodos Foram utilizados50volumes tridimensionais (3D)deuma série não consecutiva de mulheres com suspeita de malformação uterina. Dois examinadores não especialistas avaliaram um único volume 3D do útero de cada mulher, mutuamente cegos. As seguintes medidas foram aferidas: profundidade de indentação, ângulo de indentação, espessura da parede do fundo uterino, indentação externa do fundo e relação entre indentação e a espessura da parede (I:WT, na sigla em inglês). Cada observador teve que atribuir um diagnóstico em cada caso, de acordo com os três sistemas de classificação (ESHRE/ESGE, ASRM e CUME). A concordância interobservador em relação às classificações ESHRE/ESGE, ASRM e CUME foi avaliada usando o índice kappa ponderado de Cohen (k). A concordância em relação às três classificações (ASRM versus ESHRE/ESGE, ASRM versus CUME e ESHRE/ ESGE versus CUME) também foi avaliada. Resultados A concordância interobservador entre os 2 examinadores não especialistas foi boa para a classificação ESHRE/ESGE (k = 0,74, intervalo de confiança [IC] 95%: 0,55-0,92) e muito boa para os sistemas de classificação ASRM e CUME (k = 0,95; IC 95%: 0,86-1,00; e k = 0,91; IC95%: 0,79-1,00, respectivamente). A concordância entre as classificações ESHRE/ESGE e ASRM foi moderada para ambos os examinadores. A concordância entre as classificações ESHRE/ESGE e CUME foi moderada para o examinador 1 e boa para o examinador 2. A concordância entre as classificações ASRM e CUME foi boa para ambos os examinadores. Conclusão As três classificações apresentam concordância interobservador boa (ESHRE/ESGE) ou muito boa (ASRM e CUME). A concordância entre as classificações ASRM e CUME foi maior do que entre as classificações ESHRE/ESGE e ASRM e ESHRE/ESGE e CUME.

ABSTRACT

Resumen Las malformaciones venosas son lesiones vasculares benignas infrecuentes que se presentan en el útero. Están conformadas por venas anormales, de diferentes tamaños y proporciones, con configuración espongiforme y disposición al azar. En la literatura, han sido previamente reportados algunos casos, usando el término "hemangioma cavernoso", pero según los cambios recientes en la terminología, aprobados por Sociedad Internacional para el Estudio de las Anormalidades Vasculares (ISSVA), se desaconseja el uso de este término y se sugiere el de "Malformación venosa", si se cumplen los hallazgos histopatológicos al momento de hacer el diagnóstico. Presentamos el caso de una mujer de 44 años, con cuadro de hemorragia vaginal anormal y diagnóstico clínico de miomatosis y mioma abortado por el orificio cervical interno, el estudio histopatológico reveló la presencia de una malformación venosa que comprometía el miometrio y endometrio, con formación subsecuente de un pólipo.


Abstract Venous malformations are benign vascular lesions that rarely appear in the uterus. They are made up of abnormal veins, of different sizes and proportions, with spongiform configuration and random disposition. In the literature, some cases have been previously reported, using the term "cavernous hemangioma", but according to recent changes in terminology, approved by the International Society for the Study of Vascular Abnormalities (ISSVA), the use of this term is discouraged, and the diagnosis of Venous malformation is suggested, if the histopathological findings are met. We present the case of a 44-year-old woman, with abnormal vaginal bleeding and a clinical diagnosis of myomatosis and myoma aborted by the internal cervical orifice, in whom the histopathological study revealed the presence of a venous malformation that compromised the myometrium and endometrium, with subsequent formation of a polyp.

ABSTRACT

BACKGROUND: Endometritis is the most common disease of dairy cows and traditionally treated with antibiotics. Lactic acid bacteria can inhibit the growth of pathogens and also have potential for treatment of endometritis. Using PacBio single-molecule real-time sequencing technology, we sequenced the fulllength l6S rRNA of the microbiota in uterine mucus samples from 31 cows with endometritis, treated with lactic acid bacteria (experimental [E] group) and antibiotics (control [C] group) separately. Microbiota profiles taken before and after treatment were compared. RESULTS: After both treatments, bacterial species richness was significantly higher than before, but there was no significant difference in bacterial diversity. Abundance of some bacteria increased after both lactic acid bacteria and antibiotic treatment: Lactobacillus helveticus, Lactococcus lactis, Lactococcus raffinolactis, Pseudomonas alcaligenes and Pseudomonas veronii. The bacterial species that significantly decreased in abundance varied depending on whether the cows had been treated with lactic acid bacteria or antibiotics. Abundance of Staphylococcus equorum and Treponema brennaborense increased after lactic acid bacteria treatment but decreased after antibiotic treatment. According to COG-based functional metagenomic predictions, 384 functional proteins were significantly differently expressed after treatment. E and C group protein expression pathways were significantly higher than before treatment (p < 0.05). CONCLUSIONS: In this study, we found that lactic acid bacteria could cure endometritis and restore a normal physiological state, while avoiding the disadvantages of antibiotic treatment, such as the reductions in abundance of beneficial microbiota. This suggests that lactic acid bacteria treatment has potential as an alternative to antibiotics in the treatment of endometritis in cattle.

ABSTRACT

A Hemorragia Pós-parto é a maior causa mundial de histerectomia periparto. Sua abordagem terapêutica deve ser efetuada por uma sucessão de procedimentos farmacológicos e cirúrgicos antes de se recorrer à histerectomia. O acretismo placentário se apresenta como a etiologia de hemorragia pós-parto que mais dificulta a preservação uterina. Sua incidência se relaciona estritamente com a elevação contemporânea das taxas de cesárea, com os demais procedimentos cirúrgicos no útero e com a implantação segmentar da placenta. Com isso, objetiva-se relatar um caso de placenta prévia central e increta tratado por meio de excisão miometrial segmentar com reconstrução da parede uterina durante cesariana. A abordagem cirúrgica foi instituída seguindo os passos de localização per-operatória da placenta, realização de histerotomia corporal alta transversa, extração fetal, confirmação clínica do incretismo placentário, manutenção da placenta in situ, ligadura bilateral dos ramos ascendentes das artérias uterinas, ressecção de todo o segmento uterino anterior invadido por cotilédones placentários, reconstrução da parede uterina, histerorrafia, salpingotripsia bilateral, revisão da cavidade abdominal e laparorrafia. A técnica cirúrgica adotada foi eficiente na obtenção do controle hemorrágico durante a cesariana e não foi associada a complicações per ou pós-operatórias.


Postpartum Hemorrhage is the largest worldwide cause of peripartum hysterectomy. Its therapeutic approach must be performed by a succession of pharmacological and surgical procedures prior to hysterectomy. Placental accreta presents as the etiology of postpartum haemorrhage that makes uterine preservation more difficult. Its incidence is strictly related to the contemporary elevation of cesarean rates, other surgical procedures in the uterus and segmentar implantation of the placenta. We aim to report a case of central and increta placenta treated through segmental myometrial excision with reconstruction of the uterine wall during cesarean section. The surgical approach was instituted following the perioperative localization of the placenta, transverse corporal hysterotomy, fetal extraction, clinical confirmation of placental invasive aspects, maintenance of the placenta in situ, bilateral ligation of the uterine artery ascending branches, resection of the all anterior uterine segment invaded by placental cotyledons, reconstruction of the uterine wall, hysterorrhaphy, bilateral salpingotripsy, revision of the abdominal cavity and laparorrhaphy. The surgical technique adopted was efficient in obtaining hemorrhagic control during cesarean section and was not associated with per or postoperative complications.

ABSTRACT

Gestational hypertension and pre-eclampsia are important causes of perinatal morbidity. The objective of the present study was to determine the increase in relative risk for developing hypertensive disorders of pregnancy based on the evaluation of pregnant women between 20 and 25 weeks of gestation, and to correlate the findings at this period with the outcome of pregnancy. We conducted a prospective cohort study, with a convenience sample of 1417 patients evaluated at this gestational age, of which 1306 were contacted at childbirth. We detected an increased relative risk of 2.69 (95%CI: 1.86 to 3.89) associated with pulsatility index of the uterine arteries, a 2.8 increase (95%CI: 1.58 to 5.03) in relative risk attributed to maternal age above 35 years, a 1.68 increase (95%CI: 1.17 to 2.40) attributed to parity greater than or equal to 3, and a 5.35 increase (95%CI: 4.18 to 6.85) attributed to chronic hypertension and obesity, with a progressive increase in relative risk according to the degree of overweight, i.e., grades 1, 2, 3, and morbid obesity (2.58, 3.06, 5.84, and 7.28, respectively).

ABSTRACT

This study aimed to explore the characteristic role of Puerariae Lobatae Radix(PLR) in Gegen Decoction for the treatment of primary dysmenorrhea(PD). Estrogen(E_2) was combined with oxytocin to establish a mouse model of PD. The mice were randomly divided into a normal group, a model group, a Gegen Decoction group, a PLR-free Gegen Decoction group, a PLR group, and a positive drug group(ibuprofen). Writhing response times and writhing incubation of mice in each group were tested by behavio-ral assessment, and the serum levels of prostaglandin F_(2α)(PGF_(2α)), prostaglandin E_2(PGE_2), E_2, and progesterone(PROG) were detected by ELISA kits. Western blot method was adopted to detect cyclooxygenase-2(COX-2) and estrogen receptor alpha(ER_α) expression levels in uterine tissues. Doppler ultrasound was employed to detect changes in uterine artery blood flow in mice, including peak systolic blood flow velocity(maximum velocity), end-diastolic velocity(minimum velocity), peak systolic blood flow velocity/end-diastolic velocity(S/D), pulsatility index(PI), and resistive index(RI). Histopathological changes in the uterus were detected by HE staining. Based on the oxytocin-induced isolated uterine contraction model, the effects of Gegen Decoction, PLR-free Gegen Decoction, and PLR on the amplitude, frequency, and activity of isolated uterine contraction were compared to investigate the role of PLR in Gegen Decoction for the treatment of PD. The results showed that compared with the Gegen Decoction group, the PLR-free Gegen Decoction improved the indicators of PD except for E_2 content, ER_α expression, and uterine artery blood flow. PLR could significantly down-regulate the serum content of E_2 and the protein expression of uterine ER_α, and improve the uterine artery blood flow. The data suggested that PLR, as the sovereign drug of Gegen Decoction, might function in Gegen Decoction for the treatment of PD by mediating E_(2 )and improving the uterine artery blood flow.

ABSTRACT

Inositol 1,4,5-trisphosphate receptor 1 (ITPR1) is an important intracellular channel for releasing Ca²⁺. In order to investigate the effects of the ITPR1 overexpression on Ca²⁺ concentration and lipid content in duck uterine epithelial cells and its effects on calcium transport-related genes, the structural domain of ITPR1 gene of duck was cloned into an eukaryotic expression vector and transfected into duck uterine epithelial cells. The overexpression of the ITPR1 gene, the concentration of Ca²⁺, the lipid content, and the expression of other 6 calcium transport-related genes was determined. The results showed that the concentration of Ca²⁺ in uterine epithelial cells was significantly reduced after transfection (P<0.05), the triglyceride content was significantly increased (P<0.01), and the high-density lipoprotein content was significantly decreased (P<0.01). The correlation analysis results showed that the overexpression of the C-terminal half of the ITPR1 gene was significantly positively correlated with the total cholesterol content (P<0.01), which was significantly positively correlated with the low-density lipoprotein content (P<0.05). The overexpression of the N-terminal half of the ITPR1 gene was significantly positively correlated with the triglyceride content (P<0.01), which was significantly negatively correlated with the concentration of Ca²⁺ (P<0.05). RT-qPCR results of 6 calcium transport-related genes showed that the overexpression of the C-terminal half of the ITPR1 gene significantly inhibited the expression of the IP3R2, VDAC2 and CAV1 genes, and the overexpression of the N-terminal half of the ITPR1 gene significantly promoted the expression of the IP3R3 and CACNA2D1 genes. In conclusion, the ITPR1 gene overexpression can promote Ca²⁺ release in duck uterus epithelial cells, promote the synthesis of triglyceride, low-density lipoprotein and cholesterol, and inhibit the production of high-density lipoprotein, and the ITPR1 gene overexpression affected the expression of all 6 calcium transport-related genes.

ABSTRACT

The transcription factor X-box binding protein-1 (XBP1) plays a key role in unfolded protein reaction. This study was aimed to investigate the expression pattern and regulation of XBP1 in the mouse uterus during early pregnancy. The methods of immunohistochemistry (IHC) and real time quantitative RT-PCR were used to test XBP1 expression in early pregnancy, artificial decidualization, oestrous cycle and hormone-regulated mouse models. The results showed that XBP1 was spatiotemporally expressed in mouse uterus during early pregnancy. The XBP1 protein was mainly detected in the luminal and glandular epithelia on days 1-4 of pregnancy, and was strongly detected in the decidual area on days 5-8 of pregnancy. Similarly, XBP1 expression was also mainly expressed in decidual cells following artificial decidualization. During the oestrous cycle, Xbp1, Xbp1u, and Xbp1s mRNA was predominantly present in proestrus. In the ovariectomized uterus, the expression of XBP1 in luminal and glandular epithelia was up-regulated after estrogen treatment. These results suggest that XBP1 is associated with embryo implantation and decidualization during early pregnancy in mice, and the expression of XBP1 in luminal and glandular epithelia may be regulated by estrogen.

ABSTRACT

Natural killer (NK) cells are the main immune cells at the maternal-fetal interface and accumulate in the uterine decidua in early pregnancy. Many studies have shown that NK cells at the maternal-fetal interface have unique phenotypes and play critical roles in various processes, including immune tolerance during pregnancy, decidualization, invasion of trophoblasts, remodeling of the uterine spiral artery, formation of the placenta and growth of embryo. However, specific functions of NK cells and their mechanism remain to be fully elucidated. This review summarizes the research progress of NK cells at the maternal-fetal interface and their roles in the pregnancy-related disorders in recent years. The aims of this review are to gain deep insight of the function of NK cells at the maternal-fetal interface and provide new ideas for intervention of pregnancy-related diseases.

ABSTRACT

O conhecimento da anatomia de qualquer animal silvestre é de fundamental importância para sua preservação e proteção. Neste contexto, o presente estudo objetivou descrever a morfologia do sistema reprodutor feminino de Alouatta belzebul. Foram utilizados seis espécimes de A. belzebul, fêmeas, adultas, e livres de lesões. Observou-se macroscopicamente que os ovários têm características morfológicas em formato ovoides, com superfície lisa, e, na análise histológica na região de córtex, evidenciou-se folículos ovarianos em diferentes estágios de desenvolvimento. As tubas uterinas anatomicamente são finas e curvilíneas, apresentando uma camada mucosa, uma muscular e outra serosa. O útero possui formato simples, com fundo globoso, com um miométrio altamente vascularizado, sendo organizado em feixes de fibras musculares lisas. A estrutura anatômica da vagina apresentou-se como um tubo muscular longo de paredes finas, onde, na região vestibular, o óstio externo da uretra é marcado por uma papila uretral bilobada e, na região de vulva, em sua porção caudal, contatou-se um clitóris bem desenvolvido. No que concerne à análise histológica da vagina, verificou-se, em região de mucosa vaginal, um extrato basal composto por epitélio estratificado pavimentoso não queratinizado atrófico. As descrições morfológicas fornecem, de forma inédita, informações importantes relativas à anatomia macroscópica e microscópica do sistema reprodutor feminino dessa espécie.(AU)


Knowledge of the anatomy of any wild animal is of fundamental importance for its preservation and protection. In this context the present study aimed to describe the morphology of the female reproductive system of A. belzebul. We used 6 specimens of A. belzebul, female, adult and free of lesions. It was macroscopically observed that the ovaries are ovoid with smooth surface and the histological analysis in cortical region showed ovarian follicles in different stages of development. The fallopian tubes are anatomically thin and curvilinear, with one mucous layer, one muscular and one serous layer. The uterus was presented in a simple format with a globular fundus, with a highly vascularized myometrium, being organized in bundles of smooth muscle fibers. The anatomical structure of the vagina presented itself as a long thin-walled muscular tube where in the vestibular region the external orifice of the urethra is marked by a bilobed urethral papilla and in the caudal portion in its caudal portion a well-developed clitoris. Regarding the histological analysis of the vagina, a basal extract composed of atrophic non-keratinized stratified squamous epithelium was found in the vaginal mucosa region. The morphological descriptions provide important information regarding the macroscopic and microscopic anatomy of the female reproductive system of this species in an unprecedented way.(AU)

ABSTRACT

Abstract Objective To evaluate the obstetric outcomes of singleton high-risk pregnancies with a small size uterine fibroid. Methods This retrospective cohort study was conducted among 172 high-risk pregnant women who were followed-up by a single surgeon between 2016 and 2019. Pregnant women with preconceptionally diagnosed small size (< 5 cm) single uterine fibroids (n = 25) were compared with pregnant women without uterine fibroids (n = 147) in terms of obstetric outcomes. Results There was no statistically significant difference between the groups in terms of adverse pregnancy outcomes. The size of the fibroids was increased in 60% of the cases, and the growth percentage of the fibroids was 25% during pregnancy. Intrapartum and short-term complication was not observed in women who underwent cesarean myomectomy. Conclusion Small size uterine fibroids seem to have no adverse effect on pregnancy outcomes even in high-risk pregnancies, and cesarean myomectomy may be safelyperformed in properly selected cases.

ABSTRACT

RESUMEN Objetivo: se ha recomendado a los profesionales que tengan como proyecto realizar trasplante uterino, hacer previamente trabajos experimentales en animales. Este trabajo describe el procedimiento del trasplante uterino en ovejas y los resultados a corto y mediano plazo. Materiales y métodos: estudio de cirugía experimental en ovejas sometidas a explante y trasplante uterino. A cuatro ovejas de 40-50 kg de peso les fue trasplantado el útero (ortotópico) de cuatro ovejas vivas donantes. Se utilizó técnica de anastomosis vascular término-lateral, la vagina se suturó en un plano y el útero se fijó a la pared pélvica. Se describen las complicaciones y la evolución a 180 días Resultados: se realizó la cirugía de trasplante en las cuatro ovejas. El tiempo quirúrgico fue de 240 minutos (min) en el primer procedimiento y de 185 min en el último, y el tiempo de isquemia caliente se redujo de 42 a 22 min. Una oveja murió al séptimo día posoperatorio por una complicación intraoperatoria ajena a las anastomosis vasculares. Otra oveja que fue trasplantada desarrolló infección-local vaginal manejada con metronidazol, con evolución satisfactoria. Las tres ovejas no habían presentado rechazo al trasplante a los 6 meses. Conclusiones: el modelo ovino permite entrenamiento quirúrgico en cirugía experimental de trasplante uterino. Para los autores constituyó adquisición de conocimiento y avanzar hacia la realización futura del trasplante uterino en mujeres con Infertilidad absoluta por factor uterino en Colombia.


ABSTRACT Objective: It has been recommended that professionals who are planning to perform uterine transplantation should first carry out animal experiments. This paper describes the procedure for uterine transplant in sheep, as well as short and medium-term results. Materials and methods: Experimental surgery study in sheep subjected to uterine explantation and transplant. Four 40-50 kg sheep received uteri transplantation (orthotopic) from four live donors. End-to-side vascular anastomosis was used, the vagina was sutured on one plane and the uterus was fixed to the pelvic wall. Complications and 180-day evolution are described. Results: Transplant surgery was accomplished in the 4 sheep. Surgical time in the first procedure was 240 minutes, while the last procedure lasted 185 minutes. Warm ischemia time was reduced from 42 to 22 minutes. One sheep died on the seventh postoperative day due to an intraoperative complication unrelated to the vascular anastomosis. A second sheep developed local vaginal infection treated with metronidazole and evolved satisfactorily. No transplant rejection had occurred in the remaining 3 sheep after 6 months. Conclusions: The ovine model allowed surgical training in experimental uterine transplant surgery. For the authors, it offered an opportunity to gain knowledge and make progress towards future uterus transplantation in women with uterine factor infertility in Colombia.

ABSTRACT

Introducción: Los tumores de gran tamaño han sido descritos a través de la historia, entre ellos los ginecológicos y los de ovario cuando pesan más de 12 kg constituyen una rareza médica. Las masas tumorales en hemiabdomen inferior son causas frecuentes de consulta en cirugía general. Dentro de estas, los quistes de ovarios son los que con más frecuencia se diagnostican. Objetivo: Describir el caso de un quiste gigante de ovario en una paciente que fue atendida en consulta de cirugia general por aumento de tamaño en el abdomen de varios años de evolución. Caso clínico: Se expone el caso de una paciente femenina, con antecedentes de salud, que acude al servicio de cirugía general por aumento de volumen del abdomen, progresivo, insidioso de 2 años de evolución. Se diagnostica masa quística dependiente de ovario y en el transoperatorio se constata una tumoración quística del ovario que en el análisis histopatológico informa un cistoadenoma seroso de ovario. Conclusión: Los tumores del ovario no son tan frecuentes como los del útero y los de la mama, pero constituyen el tercer grupo de tumores benignos y malignos de la mujer. Se presentó el caso por lo infrecuente que resulta, la escasa frecuencia de reporte de estos casos lo cual aporta conocimiento a la comunidad médica sobre el tema(AU)


Introduction: Large tumors have been described throughout history, including gynecological tumors, and ovarian tumors when they weigh more than 12 kg constitute a medical rarity. Tumor masses in lower hemiabdomen are frequent causes of consultation in general surgery. Within these, ovarian cysts are the most frequently diagnosed. Objective: To describe the case of a giant ovarian cyst in a patient who was treated in a general surgery consultation due to an increase in abdomen size of several years of evolution. Clinical case: The case of a female patient, with a history of health, which goes to the general surgery service due to an increase in abdomen volume, progressive, insidious of 2 years of evolution, is presented. Ovarian-dependent cystic mass is diagnosed and a cystic tumor of the ovary is found in the transoperative period, which in the histopathological analysis reports a serous ovarian cystadenoma. Conclusion: Ovarian tumors are not as frequent as those of the uterus and those of the breast, but they constitute the third group of benign and malignant tumors of women. The case was presented because of the infrequent result, the low frequency of reporting these cases, which brings knowledge to the medical community on the subject(AU)

ABSTRACT

RESUMEN El embarazo es un proceso natural que debe concebirse sin complicaciones; sin embargo, los desenlaces obstétricos fatales en gestaciones previas, son marcadores importantes de un riesgo incrementado de morbimortalidad materna y perinatal en los próximos embarazos. La hemorragia obstétrica posparto es una de las más frecuentes y severas complicaciones del periparto; como una alternativa terapéutica útil en esos casos, el manejo quirúrgico conservador de útero permite mantener la fertilidad en mujeres con paridad no satisfecha, y mejorar su calidad de vida, aunque en muchas ocasiones, por causas diversas, esto no es posible. Se presenta el caso de una paciente de 26 años de edad, con historia obstétrica de tres embarazos, un parto y un aborto (provocado); y el antecedente de complicación obstétrica hemorrágica en embarazo anterior por atonía uterina, la cual requirió tratamiento quirúrgico conservador con técnicas combinadas (suturas compresivas de Hayman, Ho-Cho y ligadura bilateral de las arterias uterinas). Dos años después, acudió a los servicios obstétricos con gestación de 16 semanas (alto riesgo obstétrico). Este artículo tiene el objetivo de exponer el informe de una paciente en la que se logró la concepción de un embarazo posterior a la realización de cirugía conservadora del útero.


ABSTRACT Pregnancy is a natural process that must be conceived without complications; however, fatal obstetric outcomes in previous pregnancies are important markers of an increased risk of maternal and perinatal morbidity and mortality in future pregnancies. Postpartum obstetric hemorrhage is one of the most frequent and severe complications of the peripartum; As a useful therapeutic alternative in these cases, conservative surgical management of the uterus allows fertility to be maintained in women with unsatisfied parity, and improves their quality of life, although in many cases, for various reasons, this is not possible. The case of a 26-year-old patient is presented, with an obstetric history of three pregnancies, one delivery and one abortion (provoked); and a history of hemorrhagic obstetric complication in previous pregnancy due to uterine atony, which required conservative surgical treatment with combined techniques (Hayman, Ho-Cho compression sutures and bilateral ligation of the uterine arteries). Two years later, she attended obstetric services with a 16-week gestation (high obstetric risk). This article aims to present the report of a patient in whom the conception of a pregnancy was achieved after performing conservative surgery on the uterus.

ABSTRACT

An adult, female, 31kg body weight, free range Myrmecophaga tridactyla was referred for medical consultation due to apathy, dehydration, intense flatulence and fetid stools. The animal was submitted to chemical restraint and physical examination, blood count, fecal analysis, and vaginal cytology and abdominal ultrasonography were performed. Good nutritional status and clinical variables within the normal range were observed at physical examination. At vaginal cytology leukocytes, spermatozoa and a large proportion of cornified cells (superficial) were observed, indicating estrus and recent copula. At ultrasound examination it was possible to locate, identify, evaluate and measure the ovaries and the uterine structures, cervix, body, lumen, myometrium and endometrium, a fact never reported in the literature for this species. These data can be used as reference for clinical evaluation of the reproductive tract in Myrmecophaga tridactyla females considered vulnerable species, for the diagnosis of reproductive pathologies, biotechnologies application or estrous cycle evaluation.(AU)


Uma fêmea, com 31kg de peso corporal, de Myrmecophaga tridactyla, de vida livre, foi apresentada para consulta médica em razão de apatia, desidratação, flatulência intensa e fezes fétidas. O animal foi submetido à contenção química e foram realizados exame físico, hemograma, análise fecal, citologia vaginal e ultrassonografia abdominal. Ao exame físico, foi determinado bom estado nutricional e variáveis clínicas dentro da faixa de normalidade. Na citologia vaginal, foram observados leucócitos, espermatozoides e uma grande proporção de células cornificadas (superficiais), indicando estro e cópula recente. No exame ultrassonográfico, foi possível localizar, identificar, avaliar e mensurar os ovários e as estruturas uterinas, o colo do útero, o corpo do útero, o lúmen, o miométrio e o endométrio, fato nunca relatado na literatura para essa espécie. Esses dados podem ser utilizados como referência para avaliação clínica do trato reprodutivo de fêmeas de Myrmecophaga tridactyla considerada espécie vulnerável, para o diagnóstico de patologias reprodutivas, aplicação de biotecnologias ou avaliação do ciclo estral.(AU)

ABSTRACT

An alternative hyper-ovulator inducer to replace clomiphene citrate (CC) is needed as it is unsuitable for women with polycystic ovarian syndrome and is associated with low pregnancy rates. Anastrozole is an effective hyper-ovulator inducer, but has not been well researched. In order to determine the effectiveness of anastrozole as a hyper-ovulator inducer and to an extent compare it with CC in similar situations, this study ascertained the effects of these drugs on the expression of the focal adhesion proteins, paxillin and FAK, which are uterine receptivity markers in the surface luminal uterine epithelial cells of day 1 and day 6 pregnant Wistar rats. The results show that paxillin is localized in focal adhesions at the base of the uterine epithelial cells at day 1 of pregnancy whereas at day 6, paxillin disassembles from the basal focal adhesions and localizes and increases its expression apically. FAK is faintly expressed at the basal aspect of the uterine epithelial cells while moderately expressed at the cell-to-cell contact at day 1 in all groups from where it disassembles and relocates apically and becomes more intensely expressed at day 6 of pregnancy in untreated and anastrozole treated rats. Although paxillin is localized apically at day 6, its expression is significantly down-regulated with CC treatment suggesting its interference with the implantation process. These findings seem to suggest that anastrozole could favor implantation.


Para reemplazar el citrato de clomifeno (CC) es necesario un inductor de hiperovulación alternativo, ya que no es adecuado para mujeres con síndrome de ovario poliquístico y está asociado con tasas bajas de embarazo. El anastrozol es un inductor eficaz del hiper-ovulador, pero no se ha investigado adecuadamente. Con el fin de determinar la efectividad del anastrozol como inductor del hiper-ovulador y, en cierta medida, compararlo con CC en situaciones similares, este estudio determinó los efectos de estos fármacos en la expresión de las proteínas de adhesión focal, paxillin y FAK, uterinas marcadores de receptividad en la superficie luminal de células uterinas epiteliales, del día 1 y día 6 en ratas Wistar preñadas. Los resultados muestran que la paxilina se localiza en adherencias focales en la base de las células epiteliales uterinas en el día 1 del embarazo, mientras que en el día 6, la paxilina se desmonta de las adherencias focales basales y localiza y aumenta su expresión apicalmente. FAK se expresa débilmente en el aspecto basal de las células epiteliales uterinas, mientras que se expresa moderadamente en el contacto de célula a célula en el día 1 en todos los grupos, donde se separa y se reubica apicalmente y se expresa con mayor intensidad el día 6 de la preñez, en pacientes no tratados y tratados. ratas tratadas con anastrozol. Aunque la paxillina se localiza apicalmente en el día 6, su expresión está significativamente disminuida con el tratamiento con CC, lo que sugiere su interferencia con el proceso de implantación. Estos hallazgos sugieren que el anastrozol podría favorecer el proceso de implantación.

ABSTRACT

Inadequate exposure of the female reproductive system to steroids in uterine developmental periods can partially inhibit the development of endometrial glands in dogs. However, the effects of steroids on the formed glands functionality remain unknown, as well as the possible occurrence of endometrial fibrosis. This study aimed to evaluate the secretory activity of endometrial glands in prebubertal female dogs submitted to a protocol of partial ablation of the uterine adenogenesis. Sixteen females of non-specific breed were distributed into two groups; MPA (n=8), females that received applications of medroxyprogesterone acetate every 3 weeks; and C (n=8) untreated control females. Ovariohysterectomy was performed in all animals at the age of 6 months and evaluated the uterine horns by histological and histochemistry exams. The secretion intensity (degrees 1-4) was evaluated using periodic acid-Schiff (PAS) and alcian blue (AB) pH 2.5. Histological evaluation was performed using Masson's trichrome and toluidine blue. Only degree 1 and 2 marks for PAS were observed in both groups, with no difference of uterine secretion intensity between the groups regarding the degrees found. However, the MPA group revealed higher intensity of uterine secretion compared to group C (p<0.05). Staining with AB pH 2.5 also revealed only degree 1 and 2 marks in both groups, with no statistically significance between them. Masson's trichrome staining revealed no marks in the periglandular region in both groups. A higher among of mast cells was observed in the myometrial region of the uterus in both groups. Prepubertal female dogs with partial ablation of the uterine adenogenesis present minimal uterine secretory activity, absence of periglandular fibrosis and increased presence of mast cells in the myometrium compared to endometrium.(AU)


A exposição inadequada do sistema reprodutor feminino a esteróides em períodos do desenvolvimento uterino pode inibir parcialmente o desenvolvimento das glândulas endometriais em cães. Entretanto, não se conhece os efeitos dos esteróides sobre a funcionalidade das glândulas formadas, bem como a possível ocorrência de fibrose endometrial. Objetivou-se avaliar a atividade secretória das glândulas endometriais de cadelas pré-púberes submetidas a protocolo de ablação parcial da adenogênese uterina. Foram utilizadas 16 fêmeas, sem-raça-definida, distribuídas nos grupos MPA (n=8), fêmeas que receberam aplicações de acetato de medroxiprogesterona a cada 3 semanas, e C (n=8), fêmeas controle não tratadas. Aos seis meses de idade, foi realizada ovariohisterectomia em todos os animais, e avaliados os cornos uterinos pelo exame histológico e de histoquímica. Para avaliar a intensidade de secreção (graus 1-4), foram utilizadas periodic acid-Schiff e alcian blue (AB) pH 2,5. Para a avaliação histológica foram utilizados tricrômico de Masson e azul de toluidina. Apenas marcações graus 1 e 2 foram observadas para PAS em ambos os grupos, sem diferença na intensidade de secreção uterina entre grupos com relação aos graus encontrados. Entretanto, o grupo MPA apresentou maior intensidade de secreção uterina em relação ao grupo C (p<0,05). Com relação ao AB pH 2,5, em ambos os grupos também foram encontradas apenas marcações de graus 1 e 2, sem diferença estatística entre grupos. Não foram observadas marcações para a coloração de tricrômico de Masson na região periglandular, em ambos os grupos. Foi observada maior quantidade de mastócitos presentes no útero na região do miométrio, em ambos os grupos. Conclui-se que cadelas pré-púberes com ablação parcial da adenogênese uterina apresentam mínima atividade secretória uterina, ausência de fibrose periglandular e maior presença de mastócitos no miométrio em relação ao endométrio.(AU)
