Downregulation of lncrna uca1 as a diagnostic and prognostic biomarker for ovarian endometriosis

SUMMARY OBJECTIVE: Ovarian endometriosis seriously affects the quality of life of females, and long non-coding RNA lncRNA urothelial carcinoma-associated 1 (UCA1) plays pivotal roles in the pathogenesis of various ovarian diseases. However, the involvement of lncRNA UCA1 in ovarian endometriosis remains unknown to date. Therefore, the present study aims to study the role of UCA1 in ovarian endometriosis. METHODS: A total of 98 patients with ovarian endometriosis and 28 healthy females were included. The expression of lncRNA UCA1 in ectopic and eutopic endometrium tissues of ovarian endometriosis patients and controls was detected using qRT-PCR. A ROC curve analysis was performed to evaluate the diagnostic values of serum lncRNA UCA1 for ovarian endometriosis. Patients were followed up for 2 years after discharge, and the recurrence of ovarian endometriosis was recorded. RESULTS: The expression level of lncRNA UCA1 was significantly higher in ectopic endometrium tissues than in paired eutopic endometrium tissues for most of the patients. The serum lncRNA UCA1 level showed no significant correlations with either patients' age or living habits. After the treatment, the serum lncRNA UCA1 level increased, and serum levels of lncRNA UCA1 on the day of discharge were significantly lower in patients with recurrence than those in patients without recurrence. Conclusion: The downregulation of lncRNA UCA1 is involved in the pathogenesis of ovarian endometriosis and may serve as a promising diagnostic and prognostic biomarker for the disease.

RESUMO OBJETIVO: A endometriose ovariana afeta seriamente a qualidade de vida das mulheres, e o carcinoma urotelial 1 de urcélio de RNA não codificador longo 1 (UCA1) desempenha um papel crucial na patogênese de várias doenças ovarianas. No entanto, o envolvimento do lncRNA UCA1 na endometriose ovariana permanece desconhecido até o momento. Portanto, o presente estudo tem como objetivo estudar o papel do UCA1 na endometriose ovariana. Métodos: Um total de 98 pacientes com endometriose ovariana e de 28 mulheres saudáveis foi incluído. A expressão de lncRNA UCA1 em tecidos de endométrio ectópico e eutópico de pacientes com endometriose ovariana e controles foi detectada por qRT-PCR. A análise da curva ROC foi realizada para avaliar os valores diagnósticos do lncRNA UCA1 sérico para endometriose ovariana. Os pacientes foram acompanhados por dois anos após a alta, e a recorrência da endometriose ovariana foi registrada. RESULTADOS: O nível de expressão do lncRNA O UCA1 foi significativamente maior nos tecidos do endométrio ectópico do que nos tecidos do endométrio eutópico pareados para a maioria dos pacientes. O nível sérico de UCA1 foi diminuído com a progressão da endometriose ovariana. O soro UCA1 pode ser usado para diagnosticar com precisão a endometriose ovariana. O nível sérico de UCA1 não apresentou correlações significativas com a idade ou com os hábitos de vida dos pacientes. Após o tratamento, o nível sérico do lncRNA UCA1 foi aumentado, e os níveis séricos de lncRNA UCA1 no dia da alta foram significativamente menores nos pacientes com recidiva do que naqueles sem recorrência. CONCLUSÃO: A regulação negativa do lncRNA UCA1 está envolvida na patogênese da endometriose ovariana e pode servir como um promissor biomarcador diagnóstico e prognóstico para a doença.

Tumores ováricos en niñas y adolescentes / Ovarían masses in infant-juvenile age

Introducción. El tratamiento quirúrgico adecuado para las pacientes pediátricas con lesiones ováricas es heterogéneo, y en las niñas es conveniente conservar los ovarios. El objetivo de este estudio es analizar los hallazgos relacionados con un grupo de pacientes a las que se operó por lesiones ováricas. Pacientes y métodos. Un estudio retrospectivo realizado durante 13 años con 56 pacientes menores de 17 años. Estas pacientes se dividieron en 3 grupos según el diagnóstico de patología ovárica: 25 tenían lesiones funcionales (quistes y torsión), 18 tenían lesiones ováricas epiteliales y 13 tenían tumores germinales. Se comparó a estos tres grupos en términos de menarquia, torsión, edad, duración, tamaño, dolor, tumor, vómitos, menstruación irregular, ubicación y tipo de operación. Resultados. Enestosgrupos,fueronmásfrecuentes los quistes foliculares, los cistoadenomas serosos y los teratomas. La media de edad de las pacientes fue de 12,18 ± 4,84 años. Los síntomas y signos más frecuentes fueron dolor (85,7%) e hinchazón (37,5%) en la región abdominopélvica. Se observó torsión en 21 pacientes (37,5%); la media del tamaño del tumor fue de 10,46 ± 6,55 cm. Se realizó una salpingoovariectomía (SO, por sus siglas en inglés) en 38 pacientes y una resección del quiste (CE, por sus siglas en inglés) en 18 pacientes. Se observaron más casos de torsión en las pacientes premenárquicas que en las menárquicas y en el grupo de lesiones funcionales. Se realizaron más resecciones quirúrgicas en el grupo de lesiones funcionales, y más SO en los grupos de lesiones epiteliales y tumores germinales. Conclusión. Se considera que la torsión y las patologías ováricas funcionales son frecuentes en la edad premenstrual, y las lesiones malignas son muy raras en todos los grupos etarios, por lo que se recomienda preservar la fertilidad en la cirugía.

Introduction. The appropraite surgical treatment to pediatric patients with ovarian lesions are heterogeneous and ovarian preservation is desirable in children. The aim of this study is to the discuss findings related to a set of patients who were operated on for ovarian lesions. Patients and methods. A retrospective study carried out in 13 years on 56 patients under the age of 17. These patients were divided into 3 groups according to ovarian pathologic diagnosis: 25 with functional (cyts and torsion), 18 with epithelial ovarian lesions and 13 with germ cell tumours. These three groups were compared in terms of menarche, torsion, age, duration, size, pain, mass, vomiting, irregular menstruation, location and operation type. Results. Follicle cysts, serous cyst adenomas and teratomas were the most common in these groups. The mean age of the patients was 12.18+4.84 years. The most common symptoms and signs were abdominal-pelvic pain (85.7%) and swelling(37.5%). Torsion was seen in 21 patients (37.5%), mean mass size was found to be 10.46+6.55 cm. A salpingo-oophorectomy (SO) was performed in 38 patients and cyst excision (CE) was performed in 18 patients. In premenarcheal cases, torsion was seen more in menarcheal cases and in the functional lesion group. CE was performed more often in the functional and t SO was performed often in the epithelial and germ cells groups. Conclusion. Torsion and functional ovarian pathologies are thought to be common in premenstrual ages and malign lesions are very rare in all age groups so we recommend ovarian protective surgery should be preferred.

Ovarian Manson's Schistosomiasis: Rare Diagnosis or Underestimated Prevalence? / Esquistossomose mansônica no ovário: diagnóstico raro ou prevalência subestimada?

Abstract The occurrence of Manson's schistosomiasis in organs of the female reproductive tract is an uncommon event, given that the etiological agent for this disease is a blood parasite that inhabits the mesenteric veins. In this case report, a 45-year-old female patient reported that her first symptoms had been strong pain in the left iliac region around two years earlier. An endovaginal pelvic ultrasonography showed that the left ovary was enlarged, and the report suggested that this finding might be correlated with clinical data and tumor markers. After being examined at several healthcare services, the patient was referred to an oncology service due to suspected neoplasia, where she underwent a left ovariectomy. The result from the histopathological examination showed the presence of granulomatous inflammatory processes surrounding both viable and calcified eggs of Schistosoma mansoni. There was no evidence of any neoplastic tissue. The patient was medicated and followed-up as an outpatient.

Resumo A ocorrência da esquistossomose mansônica em órgãos do aparelho reprodutor feminino é um evento pouco comum, tendo em vista que o agente etiológico desta doença é um parasito sanguíneo que habita as veias mesentéricas. Neste relato decaso, uma paciente de 45 anos referiu como primeira sintomatologia fortes dores na região ilíaca esquerda há cerca de 2 anos. Uma ultrassonografia pélvica endovaginal identificou aumento do ovário esquerdo, e o laudo sugeriu correlacionar tal achado com dados clínicos e marcadores tumorais. Após passar por vários serviços de saúde, a paciente foi encaminhada para um serviço de oncologia por suspeita de neoplasia, sendo submetida a uma ovariectomia à esquerda. O resultado do exame histopatológico evidenciou a presença de processos inflamatórios granulomatosos em torno de ovos viáveis e calcificados de Schistosoma mansoni. Não houve qualquer evidência de tecido neoplásico. A paciente foi medicada, e seguiu em acompanhamento ambulatorial.

Genital schistosomiasis mansoni concomitant to genital tumor in areas of low endemicity: challenging diagnosis

Genital infection by Schistosoma mansoni is usually misdiagnosed in individuals who reside in, or travel to endemic areas. We describe two cases of genital tumor associated with S. mansoni infection manifested by methrorragy. Surgical specimens revealed leiomyomas in both cases associated with S. mansoni. In one of them, granulomas were found in the ovary and in the other they were found in the uterine tube. Although none presented intestinal/hepatic disease, fecal egg excretion was detected in one. Both had elevated pretreatment antibody reactivity to S. mansoni antigen, but follow-up showed different outcomes. Schistosomiasis should be considered as a diagnosis in individuals with methrorragy residing in or having traveled to endemic areas. Since diagnosis follows genital amputation, and cure control is troublesome, improvement of diagnostic tools and follow-up markers are important priorities to decrease schistosomiasis morbidity.

Edema maciço de ovário / Massive ovarian edema

O edema maciço de ovário é uma condição benigna rara caracterizada pelo aumento tumoral símile do ovário comprometido. As doenças ovarianas de importância cirúrgica da infância não são frequentes e podem ser divididas em lesões neoplásicas, em cistos não neoplásicos e em alterações inflamatórias. Os autores descrevem um caso de edema maciço de ovário em uma paciente de treze anos que referia dor abdominal associada a uma lesão sólido-cística do ovário direito, avaliada como neoplasia pela ultrassonografia. Ao exame macroscópico, o ovário era bocelado e estava aumentado de volume, medindo 9,5×6,0×5,0 cm e apresentando uma lesão sólida com áreas císticas à superfície de corte. O aspecto microscópico fundamental desse processo era a presença de edema acentuado e difuso do estroma, envolvendo folículos, e associado a uma camada cortical com espessamento fibroso superficial. O conhecimento dessa entidade é fundamental para auxiliar no diagnóstico durante a avaliação ultrassonográfica de tumores ovarianos e prevenir tratamentos incorretos.

Massive ovarian edema is a rare benign condition characterized by similar tumor growth of the affected ovary. The ovarian disorders of surgical importance of childhood are not frequent and can be divided into neoplastic lesions, non-neoplastic cysts, and inflammatory alterations. Here the authors describe the case of a massive ovarian edema in a 13-year-old female patient who reported abdominal pain associated with a solid-cystic lesion of the right ovary evaluated as a neoplasm by ultrasonography. The macroscopic examination showed ovary with increased volume, measuring 9.5×6.0×5.0 cm, and presenting a solid lesion with cystic areas at the cutting surface. The key microscopic feature of this process was the presence of pronounced diffuse edema of the stroma, involving follicles and associated with a cortical layer with superficial fibrous thickening. Knowledge of this entity is key in aiding the diagnosis during the ultrasonographic evaluation of ovarian tumors and preventing improper treatments.

Massive ovarian edema--a diagnostic dilemma: a case report.

A case of massive ovarian edema and polycystic ovaries in a 15 years old girl is being reported for its rarity. Definitive preoperative diagnosis is often not achieved and there by the patient is at a risk of losing the ovary(ies). Thus a definitive preoperative diagnosis should be ascertained to save the organ. A review on the previously reported cases with probable etiopathogenesis and emphasis on the radiological and morphological diagnosis for appropriate management has been discussed.

unusual presentation of postpartum ovarian vein thrombosis

Ovarian vein thrombosis is a rare but potentially serious complication following childbirth. The majority of patients present during the first week postpartum, with fever and right lower quadrant abdominal pain. We report an unusual case of postpartum ovarian vein thrombosis who presented with fever, low backache, and painful thighs. A high index of suspicion is crucial to diagnose and treat this condition in order to avoid serious consequences

Acute Chylous Peritonitis Mimicking Ovarian Torsion in a Patient with Advanced Gastric Carcinoma

The extravasation of chyle into the peritoneal space usually does not accompany an abrupt onset of abdominal pain with symptoms and signs of peritonitis. The rarity of this condition fails to reach preoperative diagnosis prior to laparotomy. Here, we introduce a case of chylous ascites that presented with acute abdominal pain mimicking peritonitis caused by ovarian torsion in a 41-yr-old female patient with advanced gastric carcinoma. An emergency exploratory laparotomy was performed but revealed no evidence of ovarian torsion. Only chylous ascites was discovered in the operative field. She underwent a complete abdominal hysterectomy and salphingo-oophorectomy. Only saline irrigation and suction-up were performed for the chylous ascites. The postoperative course was uneventful. Her bowel movement was restored within 1 week. She was allowed only a fat-free diet, and no evidence of re-occurrence of ascites was noted on clinical observation. She now remains under consideration for additional chemotherapy.

young woman with endometriosis of kidney

Endometriosis of kidney is a rare manifestation of a relatively common disease. We report a case in which ovarian and renal endometriosis were diagnosed concurrently. The disease was probably silent for a long time due to coexistent thyrotoxicosis modifying estrogen metabolism. Fine needle aspiration cytology clinched the diagnosis of endometriosis and avoided unnecessary nephrectomy

Manejo laparoscópico de masas anexiales: experiencia local / Laparoscopic handling of anexial masses: local experience

Se analizaron 132 pacientes evaluando características epidemiológicas y clínicas, la correlación entre ecografía y anatomía patológica, la evolución y el uso laparoscópico en el tratamiento de masas anexiales. El diagnóstico se basó en la identificación ecográfica de una masa anexial. El rango de edad fue 16-66 años. El dolor abdominal y pélvico estuvo presente en 34 por ciento de los casos; en 45 por ciento se diagnosticó la masa anexial por examen ecográfico de rutina. En 53 por ciento de las pacientes se realizó quistectomía y en 16 por ciento ooforectomía completa. En 78 por ciento la masa correspondió a ovario y en 22 por ciento a trompa. Para las masas de origen ovárico la frecuencia mayor correspondió a tumores epiteliales (22 por ciento), seguido por quistes endometriósicos con 18 por ciento. Hubo 3 complicaciones vasculares y cambio a vía abierta en 5 casos. Solo hubo 1 tumor borderline y como hallazgo un cáncer de cuello uterino. El objetivo de este trabajo es presentar la experiencia quirúrgica en el manejo laparoscópico de los tumores anexiales.

Tumores ovarianos / Ovarian tumors

Durante o transcorrer da vida, todas as mulheres desenvolvem várias massas anexais. O ovário normal funcionante produz cistos foliculares 6 a 7 vezes por ano. Em muitos casos, são autolimitados e resolvem dentro da duração de um ciclo menstrual normal. Em raras situações, eles persistem por mais tempo tornando-se condição patológica. Em meninas com menos de nove anos de idade, 80 porcento das massas ovarianas são malignas e geralmente são tumores de células germinativas. Durante a adolescência, 50 porcento são teratomas císticos maduros. Em pacientes com menos de 30 anos, 10 porcento dos tumores ovarianos são de baixo potencial de malignidade. Trinta e três por cento são teratomas císticos maduros e 25 porcento são endometriomas. Os demais são cistoadenomas serosos ou mucinosos ou cistos funcionais. Nas mulheres na pós-menopausa, com os ovários clinicamente palpáveis, apresentam maior risco de neoplasia maligna. O câncer do ovário é a causa mais comum de óbito por câncer ginecológico nos Estados Unidos. Os sintomas da doença em fase inicial são mínimos, inespecíficos ou inexistentes. Portanto, muitas pacientes são diagnosticadas em estádio avançado. São descritos muitos tipos histológicos de tumores ovarianos. Entretanto, mais de 90 porcento dos tumores malignos são de origem epitelial. O padrão de tratamento do câncer ovariano inclui o estadiamento cirúrgico e cirurgia citorredutora

Cavernous hemangioma presenting as a right adnexal mass in a child

This is the case of an 11-year-old girl who presented with a right adnexal mass and vague abdominal symptoms since seven months prior to her hospital admission for surgery. CT-scan and sonographic images were those of a benign lesion, probably ovarian torsion or infarction. Serum tumoral markers were normal. A right salpingo-oophorectomy and appendectomy were performed. Pathology examination revealed a cavernous hemangioma of the ovary. The clinicopathologic presentation of this unusual benign ovarian tumor is discussed.

Os tumores de ovario representam 1,2 a 1,5 por cento das doencas malignas , na infancia e ate 20 por cento deles, ocorrem antes da menarca. Neste trabalho e apresentada a experiencia do setor de oncologia genital feminina do Hospital das Clinicas de Porto Alegre, no tratamento...

A case of ovarian enterobiasis

A 36-year old Korean woman consulted a clinic for a regular gynecological examination, and a mass was noticed in her pelvis. She was referred to the Asan Medical Center, Seoul where transvaginal ultrasonography confirmed a pelvic mass exceeding 10 cm in diameter. She received total abdominal hysterectomy and bilateral salpingoophorectomy, and a borderline serous neoplasm with micropapillary features involving the left ovary and right ovarian serosa was histopathologically confirmed. In addition, a section of a nematode with numerous eggs was found in the parenchyma of the left ovary. The worm had degenerated but the eggs were well-preserved and were identified as those of Enterobius vermicularis. She is an incidentally recognized case of ovarian enterobiasis.

O espectro das falências ovarianas ligadas ao cromossomo X / Ovarian failure spectrum related to X chromosome

A falência ovariana manifesta-se clinicamente por amenorréia primária ou secundária, e do ponto de vista hormonal caracteriza-se pelos níveis elevados de gonadotrofinas hipofisàrias, principalmente FSH, cuja etiologia pode ser atribuída a varias causas, como reduçäo numérica ou rearranjos do cromossomo X, entre outras. Além da síndrome de Turner (monossomia do cromossomo X, com ou sem mosaicismo cromossômico), cujo principal estigma - a baixa estatura - e o infantilismo sexual apontam o diagnóstico, rearranjos do braço longo de X (Xq), ou mutaçöes instaladas em genes mapeados neste cromossomo estäo relacionados com a falência ovariana em meninas pré-púberes e em mulheres adultas jovens, sem outros sinais clínicos. Neste cromossomo, nos segmentos da falência ovariana precoce (FOP1 e FOP2) situam-se genes já relacionados à insuficiência ovariana de instalaçäo precoce. Esta revisäo trata destas alteraçöes, algumas detectadas pelas técnicas citogenéticas convencionais, outras somente por meio de recursos de biologia molecular.

Effects of contaminated endometriotic contents on quality of oocytes.

The mechanism of infertility associated with endometriosis is poorly understood. There is evidence supporting that women with ovarian endometriosis have a lower pregnancy rate than women with peritoneal lesions only. This study aimed to evaluate the effects of endometriotic contents contamination while retrieving oocytes on oocytes' quality. Thirty-eight infertile patients with endometriotic cysts from January 1993 to June 2000 were enrolled in this study. There were no statistically significant differences among the quality of oocytes and embryos from the contaminated, non-contaminated, and control group. However, the fertilization rate and pregnancy rate were impaired by the contamination of endometriotic contents. We conclude that ovarian endometriosis should be treated before starting in vitro fertilization program in order to increase the pregnancy outcome.

Ovarian granulosa cell 'tumorlet' and mature follicles with ectopic decidua in pregnancy--a case report.

Non-neoplastic, tumor like lesions are encountered in the ovaries during pregnancy. Of these pregnancy luteoma is the most common lesion mimicking an ovarian neoplasm. Ovarian granulosa cell proliferations are also reported in the ovaries removed during pregnancy as an incidental finding. The granulosa cell proliferation occurs due to the follicular stimulating hormone (FSH) like activity of human chorionic gonadotropin (hCG). We report a case of second gravida who developed uterine atonia, necessitating emergency hysterectomy. Right ovary showed extensive ectopic decidua, numerous well-formed follicles and granulosa cell tumor-like proliferation. Usually follicles are not formed in the ovaries during pregnancy. The same FSH like activity of hCG might have been responsible for the formation and maturation of follicles in this case.
