Ooforosalpingitis xantogranulomatosa. Comunicación de caso

La inflamación xantogranulomatosa del tracto genital femenino es infrecuente y es aún más rara en las trompas de Falopio y ovarios. Se presenta un caso de ooforosalpingitis xantogranulomatosa en una paciente femenina de 45 años quien asistió a consulta por presentar dolor en fosa iliaca izquierda acompañado de fiebre. La exploración bimanual mostró útero ligeramente aumentado de tamaño con masa anexial izquierda firme, no dolorosa, adherida al útero y con limitada movilidad. La evaluación ecográfica transvaginal determinó tumoración ovárica izquierda, heterogénea con paredes gruesas e irregulares con múltiples septos y ecos internos sin visualizar el ovario. Durante la cirugía, se encontraron adherencias densas desde la masa hacia la pared lateral pélvica, fosa ovárica y asas intestinales. El útero estaba desplazado por tumoración anexial quística izquierda, de color blanco grisáceo y paredes gruesas que drenaba líquido purulento fétido. El diagnóstico definitivo fue ooforosalpingitis xantogranulomatosa. Esta condición es un proceso inflamatorio poco frecuente que plantea dilemas diagnósticos. Sus manifestaciones clínicas y características de estudios por imágenes pueden simular una neoplasia pélvica maligna, por lo que es necesario un alto índice de sospecha para su diagnóstico, como diagnóstico diferencial en pacientes con tumoraciones ováricas quísticas complejas. El examen histopatológico es el estándar de oro para el diagnóstico.

Xanthogranulomatous inflammation of the female genital tract is infrequent and is even rarer in fallopian tubes and ovaries. We present a case of xanthogranulomatous oophorosalpingitis in a 45-year-old female patient who consulted for left iliac fossa pain accompanied by fever. Bimanual examination revealed a slightly enlarged uterus with a firm, non-painful left adnexal mass, adherent to the uterus and with limited mobility. Transvaginal ultrasound evaluation showed a heterogeneous left ovarian tumor with thick and irregular walls, multiple septa and internal echoes without visualization of the ovary. During surgery, dense adhesions were found from the mass to the pelvic lateral wall, ovarian fossa, and bowel loops. The uterus was displaced by a thick-walled, grayish-white, cystic left adnexal tumor draining foul-smelling purulent fluid. The definitive diagnosis was xanthogranulomatous oophorosalpingitis. This condition is a rare inflammatory process that poses diagnostic dilemmas. Its clinical manifestations and imaging features may mimic a malignant pelvic neoplasm, so a high index of suspicion is necessary for its diagnosis, as a differential diagnosis in patients with complex cystic ovarian tumors. Histopathological examination is the gold standard for diagnosis.

Up-to-Date Clinical and Biochemical Workup of the Child and the Adolescent with a Suspected Disorder of Sex Development.

BACKGROUND: The suspicion of a disorder of sex development (DSD) often arises at birth, when the newborn presents with ambiguous genitalia, or even during prenatal ultrasound assessments. Less frequently, the aspect of the external genitalia is typically female or male, and the diagnosis of DSD may be delayed until a karyotype is performed for another health issue, or until pubertal age when a girl presents with absence of thelarche and/or menarche or a boy consults for gynaecomastia and/or small testes. SUMMARY: In this review, we provide a practical, updated approach to clinical and hormonal laboratory workup of the newborn, the child, and the adolescent with a suspected DSD. We focus on how to specifically address the diagnostic approach according to the age and presentation. KEY MESSAGE: We particularly highlight the importance of a detailed anatomic description of the external and internal genitalia, adequate imaging studies or surgical exploration, the assessment of reproductive hormone levels - especially testosterone, anti-Müllerian hormone, 17-hydroxyprogesterone, and gonadotropins - and karyotyping.

Hernia inguinal tubo-ovárica izquierda estrangulada

La hernia inguinal indirecta (HHI) es la anomalía congénita más frecuente en la infancia y niñez. En las niñas, las HII deslizantes contienen principalmente el ovario con o sin trompa de Falopio. Presentamos el caso de una niña de 6 meses, que acude por tumoración inguinal izquierda, irreductible, asociada a vómitos. Es intervenida de emergencia con diagnóstico de hernia inguinal indirecta izquierda complicada, conteniendo trompa de Falopio y ovario izquierdo gangrenados. Este tipo de hernia tiene una incidencia más alta en prematuros y de sexo femenino menores de un año. La ecografía preoperatoria puede ser útil para el diagnóstico. El procedimiento para la reparación es la herniorrafia clásica con ligadura alta del saco herniario, a través de un abordaje inguinal.

Indirect inguinal hernia (IHH) is the most frequent congenital anomaly in infancy and childhood. In girls, the sliding IIHs contain mainly the ovary with or without a fallopian tube. We present the case of a 6-month-old girl who was presented with an irreducible left inguinal tumor associated with vomiting. She was operated of emergency with a diagnosis of complicated left indirect inguinal hernia containing gangrenous fallopian tube and left ovary. This type of hernia has a higher incidence in prematures and females under one year of age. Preoperative ultrasound may be helpful for diagnosis. The repair procedure is the classic herniorrhaphy with high ligation of the hernia sac, through an inguinal approach.

Alteraciones genitales en la infección por leptospiras en ratas Wistar gestadas / Genital alterations in leptospiras infection in pregnant Wistar rats

RESUMEN Introducción: la leptospirosis en Cuba se presenta de forma endémica, y a veces de forma epidémica, por lo que es un problema de salud. Su efecto sobre los genitales internos, en gestantes, ha sido poco tratado por los investigadores. Objetivo: describir las principales alteraciones en los genitales internos de ratas Wistar gestadas infestadas por leptospiras. Métodos: se realizó un estudio experimental en ratas Wistar preñadas: siete grupos con tres animales cada uno: un control negativo y seis casos con dosis de una concentración bacteriana de 300 millones de Leptospiras por mL; se inocularon dos mililitros a cada animal al cuarto día de gestadas por 17 meses. Se tomaron los genitales internos de todas las ratas el día 20 de la gestación, estos fueron procesados en parafina y teñidos con hematoxilina/eosina. Resultados: se observaron alteraciones en útero, ovarios y trompas; el mayor número de lesiones se presentaron en útero mientras que en ovarios y trompas se visualizaron la misma cantidad de lesiones. Conclusiones: la leptospirosis infectó los genitales internos con la producción de quistes, necrosis, abscesos, ooforitis y microhemorragias en ovarios; congestión vascular y hemorragias en las trompas uterinas y endometritis, hemorragias, miometritis, piometristis, perimetritis y congestión vascular en el útero. Predominaron las alteraciones congestivas y hemorrágicas.

ABSTRACT Introduction: leptospirosis in Cuba occurs endemically, and sometimes epidemically, making it a health problem. Its effect on internal genitalia in pregnant women has been little treated by researchers. Objective: to describe the main alterations in the internal genitalia of pregnant Wistar rats infested by leptospiras. Methods: an experimental study was carried out in pregnant Wistar rats: 7 groups with three animals each: 1 negative control and 6 cases with doses of a bacterial concentration of 300 million Leptospira per mL; each animal was inoculated with two milliliters on the fourth day of pregnancy for 17 months. The internal genitalia of all rats were taken on day 20 of gestation, processed in kerosene and stained with hematoxylin/eosin. Results: alterations were observed in the uterus, ovaries and tubes; the greatest number of lesions was present in the uterus while the same number of lesions was visualized in the ovaries and tubes. Conclusions: leptospirosis infected the internal genitalia producing cysts, necrosis, abscesses, oophoritis and microhemorrhages in the ovaries; vascular congestion and hemorrhages in the uterine tubes and endometritis, hemorrhages, myometritis, pyometristis, perimetritis and vascular congestion in the uterus. Congestive and hemorrhagic alterations predominated.

AMH and AMHR2 Involvement in Congenital Disorders of Sex Development.

Anti-müllerian hormone (AMH) is 1 of the 2 testicular hormones involved in male development of the genitalia during fetal life. When the testes differentiate, AMH is secreted by Sertoli cells and binds to its specific receptor type II (AMHR2) on the müllerian ducts, inducing their regression. In the female fetus, the lack of AMH allows the müllerian ducts to form the fallopian tubes, the uterus, and the upper part of the vagina. The human AMH gene maps to 19p13.3 and consists of 5 exons and 4 introns spanning 2,764 bp. The AMHR2 gene maps to 12q13.13, consists of 11 exons, and is 7,817 bp long. Defects in the AMH pathway are the underlying etiology of a subgroup of disorders of sex development (DSD) in 46,XY patients. The condition is known as the persistent müllerian duct syndrome (PMDS), characterized by the existence of a uterus and fallopian tubes in a boy with normally virilized external genitalia. Approximately 200 cases of patients with PMDS have been reported to date with clinical, biochemical, and molecular genetic characterization. An updated review is provided in this paper. With highly sensitive techniques, AMH and AMHR2 expression has also been detected in other tissues, and massive sequencing technologies have unveiled variants in AMH and AMHR2 genes in hitherto unsuspected conditions.

Proportional vascularization along the fallopian tubes and ovarian fimbria: assessment by confocal microtomography.

OBJECTIVE: To evaluate and reconstruct three-dimensional images of vascularization along the fallopian tube (FT), as well as to determine its relationship with the ovary and ovarian fimbria, and to quantify the blood vessels along the FT according to its anatomical segments, using confocal microtomography (micro-CT). MATERIALS AND METHODS: Nine specimens (six FTs and three FTs with ovaries) were fixed in a solution of 10% formalin for > 24 h at room temperature. Iodine staining was performed by soaking the specimens in 10% Lugol's solution for 24 h. All specimens were evaluated using micro-CT. A morphometric analysis was performed on the reconstructed images to quantify the vascular distribution along the FT. RESULTS: In the FTs evaluated, the density of blood vessels was significantly greater in the fimbrial segments than in the isthmic segments (p < 0.05). The ovarian fimbria was clearly identified, demonstrating the important relationship between these vessels and the FT fimbriae. CONCLUSION: We believe that the vascularization in the fimbriae is greater than and disproportional that in the other segments of FT, and that the ovarian fimbria plays an important role in the development of that difference.

OBJETIVO: Avaliar e reconstruir imagens tridimensionais da vascularização ao longo da trompa de Falópio (TF) e sua relação com o ovário e fímbria do ovário, além de quantificar os vasos sanguíneos ao longo da TF de acordo com seus segmentos anatômicos usando microtomografia confocal (micro-TC). MATERIAIS E MÉTODOS: Nove espécimes (seis com TFs e três com TFs e ovários) foram fixados em solução de formol a 10% por mais de 24 h à temperatura ambiente. A coloração com iodo foi realizada usando solução de Lugol a 10% durante 24 h. Todos os espécimes foram avaliados usando micro-TC. Uma análise morfométrica foi realizada nas imagens reconstruídas para quantificar a distribuição vascular ao longo da TF. RESULTADOS: A densidade dos vasos sanguíneos nas fímbrias foi significativamente aumentada em comparação ao segmento ístmico da TF (p < 0,05). A fímbria ovariana foi claramente identificada, demonstrando importante relação entre esses vasos e as fímbrias da TF. CONCLUSÃO: Acreditamos que as fímbrias apresentam vascularização aumentada e desproporcional em comparação com os demais segmentos da TF e que a fímbria ovariana desempenha importante papel nessa diferença.

The human endosalpinx: anatomical three-dimensional study and reconstruction using confocal microtomography.

PURPOSE: To evaluate in three dimensions (3D) the human endosalpinx and reconstruct its surface along its different anatomical segments, without the injection or insertion of luminal contrasts, using confocal microtomography (micro-CT). MATERIAL AND METHODS: 15 fallopian tubes (FT) from 14 women in reproductive age from procedures for benign disease or sterilization were selected. The specimens were fixed in formalin and stained with Lugol solution. Micro-CT studies were conducted on the specimens using protocols adapted from biological studies, to acquire images to reconstruct in 3D the endosalpinx surface. RESULTS: From these specimens, 6 presented the intra-mural segment, 14 presented the isthmus and 15 presented the ampulla and fimbria segment of the FT. The specimen presented tissue definition, and contrast sufficient for FT endosalpinx morphological analysis and lumen definition. The intramural portion presented initially a mucosal projection toward the lumen, bending on its own axis, and increased numbers of projections towards the isthmic portion, where the projections become longer more numerous. The endosalpinx becomes more tortuous, the lumen diameter increases and the mucosal projections become more bulky in the ampullary portion, with the projections less present on the antimesenteric side. The infundibular portion is marked with the organized and predictable endosalpinx, the abdominal ostium is cleared demonstrated, with the reduction of the endosalpinx volume. The fimbria demonstrated a small relation between fringes and intratubal endosalpinx. CONCLUSIONS: Microscopic anatomy of different segments of the human FT mucosa can be analyzed and reconstructed in 3D with histological correlation using micro-CT.

Introduction: The paraovarian cyst represents from 10% to 20% of the adnexal masses, it generates symptoms when it causes torsion of the annexes but this is rare. The isolated torsion of the fallopian tubes has an incidence of 1 in 1.5 million women. Objective: To show a case of isolated fallopian tube torsion (IFTT) as a complication of a paraovarian cyst at the University Hospital of Santander. Clinical case: A 17-year old female patient who presents pain in lower hemi-abdomen. After performing the ultrasound, a right paraovarian cyst is found. Her symptomatology improves within 24 hours. Therefore, she is discharged after telling her some recommendations. Two months later, she returns because of pain exacerbation caused by an adnexal mass of 5 centimeters. Now, her lab tests are normal but her new ultrasound reports an enlargement in the ovary and thickened fallopian tubes, so a laparoscopy is performed. This test shows that the right fallopian tube is twisted with necrosis and a right paraovarian cyst of 6 x 5cm. Discussion: The diagnosis of paraovarian cyst is usually incidental by ultrasound; but when there is a torsion complication, pelvic abdominal pain associated with nausea and vomiting is presented. When the physical examination is performed, 42.9% of women present an adnexal mass on palpation. The patient of this clinical case shows abdominal pain, including a tangible adnexal mass, which is evidenced by the ultrasound. For this reason, a laparoscopy is performed. The treatment of the paraovarian cyst is the follow-up; however, if it increases in size or there is persistence, it should be removed surgically due to the risk of torsion of its annexes. If it presents torsion, its handling will depend on the state of the tube. So, if at the moment of performing a distortion in it the violaceous color persists, a salpingectomy and a cystectomy must be performed in this patient. Conclusions: The diagnosis of fallopian tube torsion is performed if the patient has clinical symptoms such as acute pelvic abdominal pain, nausea, vomiting and presence of adnexal mass when performing a digital vaginal examination. Laparoscopy is the treatment of choice, and its management with cystectomy and salpingectomy depends on the vascular commitment of the cyst annexes.

Neisseria gonorrhoeae Challenge Increases Matrix Metalloproteinase-8 Expression in Fallopian Tube Explants.

Background:Neisseria gonorrhoeae (Ngo) is the etiological agent of gonorrhea, a sexually transmitted infection that initially infects the female lower genital tract. In untreated women, the bacteria can ascend to the upper genital reproductive tract and infect the fallopian tube (FTs), which is associated with salpingitis and can lead to impaired FT function and infertility. The extracellular matrix (ECM) plays an important role in cell migration and differentiation in the female genital tract, and some pathogens modify the ECM to establish successful infections. The ECM is regulated by matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs), their endogenous inhibitors; MMP deregulation causes pathological conditions in a variety of tissues. Results: The aim of this work was to analyze the expression and localization of MMP-3, MMP-8, MMP-9, and TIMP-1 in FT explants during Ngo infection using real-time PCR, immunohistochemistry, zymography and ELISA. No significant variations in MMP-3, MMP-9, and TIMP-1 transcript levels were observed. In contrast, a significant increase (p < 0.05) was observed for MMP-8 expression and was accompanied by stromal immunoreactivity in infected explants. ELISA results supported these findings and showed that MMP-8 release increased upon gonococcal infection. Conclusions: Our results indicate that gonococcal infection induces increased MMP-8 expression, which might contribute to FT damage during infection.

Câncer no ovário ou do ovário? O grande dilema atual / Cancer from de ovary or into the ovary? The current dilemma

O risco de câncer de ovário varia muito de acordo com a população estudada. Apesar de não ser o tumor maligno ginecológico mais comum é o de maior letalidade. Infelizmente, a maioria dos casos de câncer de ovário é diagnosticada em estadios avançados. Isto ocorre pois até o presente momento todos os programas de rastreio falharam. Mais recentemente, foi proposto um modelo dualístico, que agrupa os cânceres epiteliais em duas grandes categorias, designados por Tipo I e Tipo II. Os do tipo II, compostos principalmente pelos carcinomas serosos de alto grau, são agressivos e geralmente diagnosticados em estadios avançados. Apesar de todos os avanços, ainda não se conseguiu detectar uma lesão precursora do câncer de ovário. Novas teorias sobre a origem do câncer do ovário têm sido descritas e investigadas e sugerem que não é no ovário que a patologia se inicia. Essas teorias trazem novas perspectivas para o diagnóstico precoce e a prevenção deste agressivo tumor.(AU)

The risk of ovarian cancer varies according to the population studied. Although ovarian cancer is not the most common gynecological malignancy, it is the most lethal. Unfortunately, most cases of ovarian cancer are diagnosed in advanced stages. It occurs because until now all screening programs have failed. Most recently, it was proposed a dualistic model, which combines several types of epithelial ovarian cancer into two broad categories, known as Type I and Type II. The Type II is mainly composed by high-grade serous carcinomas and it is aggressive, usually diagnosed in advanced stages. Despite these advances, detect a precursor lesion of ovarian cancer is still not possible. New theories about the origin of ovarian cancer have been reported and investigated, and suggest that it is not in the ovary that pathology begins. These theories provide new perspectives for early diagnosis and prevention of this aggressive tumor.(AU)

Fallopian metaplastic papillary tumour: an atypical transdifferentiation of the tubal epithelium?

A metaplastic papillary tumor of the Fallopian tube is an extremely uncommon condition, with odd and confusing features that make it difficult to categorize as benign or borderline. Here, we summarize all the published cases to date and document the case of a 41-year-old woman diagnosed with this alteration after her last childbirth and ensuing tubal ligation. One of the tubes was bulky and filled with a caramel-like substance encircling a blurry spot. Light microscopy detailed a slender stalk covered by eosinophilic, columnar plump cells, showing atypical nuclei and focal budding. Mitotic figures were absent. The immunohistochemistry panel was positive for pan-cytokeratin, epithelial membrane antigen, cyclin D1, and hormone receptors. Additionally, a proliferation index of less than 5% was rated using Ki-67. The true nature of this tumor (reactive vs neoplastic) is uncertain. Nonetheless, its association with pregnancy suggests an adaptive change, likely similar to the atypical transdifferentiation proposed for Arias-Stella reaction.

Mycoplasmateceae species are not found in fallopian tubes of women with tubo-peritoneal infertility

BACKGROUND: The role of mycoplasmas on the development and sequelae of pelvic inflammatory disease remains controversial. The objective of the present study is to correlate directly the presence of Mycoplasmateceae through polimerase chain reaction (PCR) determinations in cervix and Fallopian tubes of infertile patients with tubo-peritoneal factor diagnosed through laparoscopy. METHODS: Thirty patients with tubo-peritoneal infertility and 30 normal fertile patients were included in the study; cervical samples and tubal flushings were obtained during laparoscopy. PCR determinations for the detection of genetic material of Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma urealiticum, Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis in cervix and tubal flushings were performed. RESULTS: No Mycoplasmataceae species as "only" microorganisms were found in tubal flushings of tubo-peritoneal infertility patients, whereas three (10%) fertile patients with normal tubes were positive for mycoplasma presence. This difference was not significant (p = 0.237). Among the 30 patients suffering from tubal infertility diagnosed through laparoscopy, Mycoplasmatecae species were not detected in the Fallopian tubes by PCR determinations, while in normal tubes from fertile patients these and other microorganisms could be found without distorting tubal anatomy. CONCLUSION: Mycoplasmateceae species were not detected in Fallopian tubes of women with tubo-peritoneal infertility.

Objective. To depict typical features of virtual hysterosalpingography (VHSG) in infertile patients. Material and methods: 2500 VHSG performed using a 64-row MDCT were evaluated. Results: Cervical abnormalities visualized corresponded to parietal irregularities (21 percent); thickened folds (9 percent); polyps (11 percent); diverticula (5 percent); cervical strictures (8 percent), and synechiae (1.5 percent). At the level of uterine cavity, polyps (44 percent); submucous myomas (8 percent); intramural and subserosal fibroids (11 percent); synechiae (10 percent); malformations (10 percent); adenomyosis (4 percent), and cesarean section scar (3 percent). Unilateral hydrosalpinx (7 percent) and bilateral hydrosalpinx (2 percent). Tubal obstruction was reported in 6 percent of cases. The average radiation dose was 0.94 mSv. Eighty-four percent of the patients reported mild pain or no postoperative discomfort. Conclusions: The virtual hysterosalpingography allowed a proper assessment of the internal genital organs, providing useful diagnostic information on infertility and other gynecological disorders. It constitutes a virtually painless, low-dose radiation technique, besides being well tolerated by patients.

Objetivo. Ilustrar los hallazgos característicos de la histerosalpingografía virtual (HSG-V) en pacientes en estudio de infertilidad.

Resultados A nivel del cuello se visualizaron irregularidades parietales (21 por ciento); pliegues engrosados (9 por ciento); pólipos (11 por ciento); divertículos (5 por ciento); estrechez (8 por ciento; y sinequias (1,5 por ciento). A nivel de la cavidad: pólipos (44 por ciento); miomas submucosos (8 por ciento); intramurales y subserosos (11 por ciento); y sinequias (10 por ciento); malformaciones (10 por ciento); adenomiosis (4 por ciento); cicatriz de cesárea (3 por ciento). Hidrosalpinx unilateral (7 por ciento) y bilateral (2 por ciento); obstrucción tubaria en el 6 por ciento de los casos. La dosis de radiación promedio fue 0.94 mSv. El 84 por ciento de los pacientes refirieron disconfort leve o ausente. Conclusiones: La HSG-Virtual permitió una adecuada evaluación de los órganos genitales internos, brindando información diagnóstica útil en infertilidad y otros desórdenes ginecológicos. Es una técnica poco dolorosa, bien tolerada por las pacientes y con baja dosis de radiación.

Nitric oxide is not involved in Neisseria gonorrhoeae-induced cellular damage of human Fallopian tubes in vitro

In the present study, we investigated whether cellular damage, as demonstrated by lactate dehydrogenase (LDH) release in the human fallopian tube (FT) infected by Neisseria gonorrhoeae (Ngo), correlated with high levels of nitric oxide synthase (NOS) mRNA and enzyme activity. Infection with Ngo induced a significant increase (~35-fold) in mRNA transcripts of the inducible isoform of NOS. Paradoxically, a reduction in NOS enzyme activity was observed in infected cultures, suggesting that gonococcal infection possibly influences translation of iNOS mRNA to the enzyme. In addition, treatment with the NOS inhibitor TRIM did not prevent gonococcal-induced cellular damage. In contrast, the addition of the inhibitor L-NAME induced a 40 percent reduction in LDH release, which correlated with a ~50 percent reduction in gonococcal numbers. Moreover, treatment of normal FT explants with an exogenous NO donor, SNAP, did not induce significant cellular damage. Taken together, our data suggest that NO does not contribute to cellular damage during infection of the human FT with Neisseria gonorrhoeae.

A aplicação de adesivo de cianoacrilato por histeroscopia e os testes de perviedade na esterilização tubária de ovelhas / Patency tests on sheep uterine tube sterilization after hysteroscopic cyanoacrylate usage

OBJETIVO: avaliar, por meio de testes de prenhez e de perviedade, a eficácia da obstrução tubária de ovelhas com adesivo de cianoacrilato aplicado por via histeroscópica. MÉTODO: 12 ovelhas adultas, com uma gestação anterior, foram distribuídas em três grupos: G-PO (n=3) submetidas à laqueadura tubária tipo Pomeroy; G-SH (n=3) aplicação de solução salina no istmo tubário por histeroscopia, e G-AD (n=6) aplicação de 0,5mL de n-butil-2-cianoacrilato no interior do istmo tubário, por histeroscopia. Depois de acasaladas por 90 dias com machos de comprovada fertilidade, as ovelhas não prenhas foram submetidas à laparotomia, retiradas as tubas uterinas, medidos os seus diâmetros e preparadas para testes de perviedade pela aplicação de azul de metileno e de pressão hidráulica (80mmHg). RESULTADOS: As ovelhas de G-PO e G-AD não ficaram prenhas (0 por cento), em contraste com as SH (100 por cento). O G-PO apresentou maior concentração de aderências (66,6 por cento) e de granulomas (100 por cento) em relação ao grupo AD (0 por cento); o adesivo manteve-se íntegro no lúmen tubário. O diâmetro da tuba uterina em G-AD (0,650 ± 0,16 cm) foi significantemente maior do que o das tubas em G-PO (0,195 ± 0,04* cm) (p=0,01). Os testes de perviedade de pressão e corante foram negativos para todo o grupo PO e somente um animal em AD mostrou-se positivo para o teste de pressão. CONCLUSÃO: a aplicação histeroscópica de cianoacrilato no lúmen tubário de ovelhas impediu eficientemente a fecundação, constituindo procedimento eficaz e de boas perspectivas para aplicação futura em humanos.

BACKGROUND: To evaluate, through pregnancy and pressure burst tests, the effectiveness of sheep uterine tube sterilization through hysteroscopic insertion of cyanoacrylate adhesive. METHODS: Adult sheep (n=12), with one previous pregnancy, were distributed as follows: PO Group (n=3) submitted to laparotomy and Pomeroy surgical procedure of tubal obstruction, Group SH (n=3) submitted to hysteroscopy application of saline solution inside the tubal isthmus, and Group AD (n=6) submitted to hysteroscopy application of 0.5 mL of n-2-butil-cyanoacrylate inside the tubal isthmus. They were allowed to copulate with fertile males during ninety days. The non pregnant sheep, at the 90th day, were submitted to laparotomy, the uterine tubes were removed and their diameters analyzed. The uterine tubes were evaluated for patency with methylene blue dye injection. The overpressure burst test (80mmHg) was then applied through the uterine cervix. Data were evaluated by t Student and Fisher test. RESULTS: All sheep from groups PO and AD did not get pregnant (0 percent) in contrast with sheep from group SH (100 percent); the adhesive remained stable inside the tubal lumen. The diameter of the proximal tube in AD group (0.650 ± 0.16cm) was significantly wider than the PO group (0.195 ± 0.04* cm) (p= 0.01). The overpressure burst and dye patency tests were negative for all animals from PO group and only one animal in AD group was positive for the pressure burst test. CONCLUSION: The hysteroscopic insertion of cyanoacrylate inside the tubal lumen of the sheep was effective to obstruct the uterine tube and to promote the sterilization, and would be an option for future applying in human beings.

Utilidad de la histerosalpingografía como método diagnóstico en la infertilidad / Usefulness of hysterosalpingography in diagnosis in infertility

Objetivo: presentar una base a nuestra experiencia el estado actual de la histerosalpingografía (HSG) discutiendo las diferentes metodologías utilizadas y los hallazgos relacionados con anormalidades tanto a nivel uterino como de las trompas de Falopio. Material y Métodos: Estudiamos 256 pacientes consecutivas desde Julio de 2004 a Mayo de 2007 con edad media de 32.3 años en los días 7 a 10 del ciclo menstrual. Se colocó espéculo y luego de la higiene y antisepsia de la cavidad vaginal se utilizó pinza listerina para la fijación uterina y se administró material de contraste iodado a la cavidad uterina a través de cánula de Rubistein con oliva plástica bajo control radioscópico. Se obtuvieron incidencias radiográficas digitales en decúbito dorsal con relleno parcial, total y ambas oblicuas. Luego de las mismas se realizó la prueba de Cotte. Resultados: En 7 casos no se pudo realizar el estudio por incapacidad de canular el orificio cervical externo. En los demás estudios los resultados fueron clasificados en normales, defectos de relleno intrauterinos, adenomiosis, anomalías mûllerianas, hidrosálpinx, espasmos tubario, obstrucción tubaria, prueba de Cotte positiva o negativa uni o bilateral y sospecha de adherencias pelvianas o masas anexiales acorde a la distribución del material de contraste en la cavidad abdominal. Conclusión: La HSG sigue siendo e la actualidad el estudio de elección para la valoración de las trompas de Falopio y también de gran utilidad para la evaluación interna de la cavidad uterina. Hemos evidenciado un incremento paulatino de las pacientes que se someten a este tipo de estudio proporcional al desarrollo de nuevas metodologías terapéuticas médicas y quirúrgicas para el tratamiento de la infertilidad.

Purpose: To show our experience related to the actual state of the hysterosalpingography including techniques and findings that compromise the uterus and the Fallopian tubes. Material and Methods:We have studied 256 patients from July 2004 till May 2007 with a media of 32.3 years of age, between the days 7 and 10 of the menstrual cycle. We have used an speculum, cleaned the vaginal cavity and afteruterus fixation, the contrast material have been introduced through a Rubistein canula with a plastic olive. We have obtained radiographs in different positions such as partial and full filled endometrial cavity, both oblique incidences and post Cotte test. Results: In 7 cases we couldn´t perform the study because of tiny external cervical orifice. In the rest of the patients thefindings have been classified in normal, uterine filling defects, adenomyosis, müllerian anomalies, hydrosalpinx, tubalspasm, tubal obstruction, positive or uni o bilateral negative Cotte test, and peritoneal or anexial masses suspicion.Conclusion: The HSG is the elective study for the study of the Fallopian tube and have great utility to evaluate theendometrial cavity. We have observed an increase in the number of patients that go through this study related to thedevelopment of new therapeutical strategies (medical or surgical) for the treatment of infertility.

Hysteroscopic sterilization with occlusion of sheep uterine tube using n-butyl-2-cyanoacrylate adhesive / Esterilização histeroscópica com oclusão da tuba uterina de ovelha com adesivo de n-butil-2-cianoacrilato

PURPOSE: To evaluate the fertility and analyze the macroscopic, microscopic and morphometric aspects of sheep uterine tube sterilization with a hysteroscopically insert of n-butyl-2-cyanoacrylate adhesive. METHODS: 12 adult sheep, with one previous pregnancy, were distributed as follows: group L (n=3) subjected to laparotomy and Pomeroy uterine tube ligation, group S (n=3) subjected to hysteroscopic application of saline solution in tube isthmus and group AD(n=6), that was subjected to hysteroscopic application of 0.5 ml of n-2-butil-cyanoacrylate in tube isthmus. They were mated with fertile males for ninety days. The non pregnant sheep, at the 90th day, were subjected to laparotomy with uterus and tubes uterine resection. The fragments of uterine tubes were fixated in 10 percent formalin and processes for histology evaluated, and slices dyes for H.E. Data were evaluated by Wilcoxon and Mann-Whitney and Fisher's exact test. RESULTS: All sheep from groups L and AD did not get pregnant (0 percent) in contrast with sheep from group S (100 percent); the adhesive remained integral in the uterine tube lumen. The percentual of adherences (66.6 percent) and fibrosis responses (100 percent) was significantly higher in the group L than group AD (0 percent) (p<0.01). The diameter of the caudal tube in group AD (2652.15 ± 45.76 mm) was significantly wider than that of the group L (1868.27 ± 56.11* μm) (p < 0.05). CONCLUSION: The hysteroscopic insertion of cyanoacrylate in the uterine tube lumen of sheep was effective to obstruct the uterine tube and to promote the sterilization.(AU)

Hysteroscopy and the butyl-cyanoacrylate on experimental sterilization of rabbit uterine tubes / Butil-cianoacrilato e histeroscopia na esterilização experimental de tubas uterinas de coelhas

PURPOSE: To assess the sterilization effectiveness on uterine tube of rabbit by the cyanoacrylate adhesive. METHODS: Hysteroscopy tubal catheterization was performed randomly in 12 animals (24 uterine tubes) assigned to the sham group (GS) and 15 animals (30 uterine tubes) to the n-butyl-cyanoacrylate (GB). The female rabbits were observed during 30, 90 and 180 days and mated to fertile males. The no pregnant rabbits were submitted to in vitro burst pressure test for patency by air insufflation (40 mmHg). The microscopic assessment was performed to parameters of damages in epithelium caused by the adhesive, the degree of inflammatory process, morphometry data values of tube diameter (UT) (cm), mucosa thickness (MT) and the myosalpinx thickness (MyT) (mm). The mucosa cells densitometry (total optical density) was expressed by the amount of DNA. The significance of the differences in histological scores and in thickness measurements were made by ANOVA test (P value < 0.05). RESULTS: In all animals of GB: the adhesive was attached to the mucosa; there was no pregnancy; no records of significant degree on inflammatory process; the patency test was negative and densitometry of DNA showed similar values to the both groups independently of observation periods. The layers thickness of GB-UT(1.118±0.117), GB-MT(0.447±0.247) and GB-MyT(0.853±0.097) were larger than the GS-UT(0.666±0.409), GS-MT(0.211±0.070) and GS-MyT(0.442±0.143). CONCLUSION: This approach offers a safe and feasible method of uterine tube obstruction.(AU)

MÉTODOS: A cateterização tubária por histeroscopia foi realizada randomicamente em 12 animais (24 tubas uterinas) formando o Grupo Sham (GS) e 15 animais (30 tubas uterinas) para o grupo do n-butil-cianoacrilato (GB). As coelhas foram observadas por 30, 90 e 180 dias e acasaladas com machos férteis. As tubas uterinas das fêmeas que não ficaram grávidas foram submetidas ao teste de pressão de rompimento in vitro, com insuflação de ar (40mmHg). A microscopia óptica estudou os danos causados ao epitélio pelo adesivo, o grau de processo inflamatório, a morfometria do diâmetro tubário (UT) (cm), da mucosa (MT) e do miosalpinge (MyT) (mm). A densitometria das células da mucosa (Densidade Optica Total) foi expressa pela contagem do DNA. As significâncias dos diferentes escores histológicos e das medidas das camadas foram avaliadas pelo Teste de ANOVA (P<0,005). RESULTADOS: Em todos os animais do GB: o adesivo estava aderido na mucosa tubária, não ocorreu prenhez, não houve significância nos graus do processo inflamatório, o teste de perviedade foi negativo e a densitometria do DNA apresentou valores similares em todos os grupos, independente do período de observação. A medida das camadas do GB-UT(1.118±0.117), GB-MT(0.447±0.247) e GB-MyT (0.853±0.097) foi maior que as dos GS-UT(0.666±0.409), GS-MT(0.211±0.070) e GS-MyT(0.442±0.143).
