    Uterine myoma is one of the most commonly encountered gynecologic problem in daily ultrasonographic practice, and is one of the few conditions with which specific histologic diagnosis is possible by ultrasonography in selected patients as well. We recently analysed ultrasonograms of 132 cases of uterine myoma and 31 cases that showed similar ultrasonographic findings of myoma, histopathologically verified in both cases. The results were as follows. 1. The diagnostic accuracy by ultrasonography was 93%. 2. The most common ultrasonographic findings of uterine myoma were nodular enlargement of uterus and irregular internal echo texture changes. 3. It was not possible to differentiate the various kinds of secondary degeneration by ultrasonography, except for calcification and cystic change. 4. It was usually unable to differentiate solitary from multiple myoma, and subserosal, interstitial and submucosal types from each other by ultrasonographic findings alone, except for the usual cases of exophytically growing subserosal mass. 5. The most frequent disease that is hard to differentiate from small uterine myoma was adenomyosis, and therefore it is considered necessary to include the adenomyosis in differential diagnosis in the diagnosis of myoma causing moderately enlarged uterus.

    Myomas represent a large part of benign gynecological pathology, widely spread in fertile female population. First step to diagnose fibroids is ultrasound (US) that can be 2-dimensional (2D), 3-dimensional (3D), Color Doppler (CD) and sonohysterography (SHG). This review develops according to MUSA's sonographic features (Morphological Uterus Sonographic Assessment). One of the main topic of interest for ultrasonographer today is endo/myometrial junctional zone (JZ), because it may be useful to discern a diagnosis of myoma and adenomyosis. Another important aspect of ultrasound is the analysis of vascularization in front of a uterine lesion. Indeed, vascular pattern can be used to make differential diagnosis between myoma-adenomyosis and leiomyosarcomas. Myomas should be described accurately according to sonographic guidelines. Sonographic features correlated with symptoms should guide an appropriate surgical or medical treatment. PMID:27014801

    Uterine myoma and adenomyosis are the two most likely diagnoses in women with hypermenorrhea, dysmenorrhea, and an enlarged uterus, but it is often not possible to make a distinction between them preoperatively. But their treatments can differ : myoma can be treated through myomectomy whereas adenomyosis require hysterectomy. In order to establish the characteristic and differential findings of myoma and adenomyosis sonographically, sonographic findings of 125 cases of pathologically proven myoma and adenomyosis were reviewed retrospectively. Histologic diagnosis were myoma in 94 patients and adenomyosis in 31 patients. The results were as follows : 1. The common sonographic findings of uterine myoma were globular enlargement or bulging contour of uterus 77.8%, loss of central endometrial echoes 66.0%, and homogeneous decreased internal echoes 35.1% or heterogeneous internal echoes 44.7%. 2. The common sonographic findings of adenomyosis were diffuse enlargement without contour change 80.6%, homogeneous hypoechoic or isoechoic internal textures 96.8%, preserved central endometrial echoes 80.6%, and thickening of posterior uterine wall 64.5%. 3. Adenomyosis was highly suggested if the uterus showed diffuse enlargement without contour change or visible nodule, homogeneous hypoechoic textures, and especially thickened posterior wall with anteriorly displaced central endometrial echoes. 4. Adenomyosis could be excluded if the patient was under 30 or above 50 years old, and especially had no previous obstetric history.

    We sought to evaluate the clinical feasibility and mid- to long-term effects of laparoscopic uterine artery occlusion before myomectomy in the treatment of uterine myomas. A total of 566 patients with uterine myoma were treated by laparoscopic uterine artery occlusion before myomectomy from October 2001 through July 2007. Mean blood loss was 88.2 +/- 52.7 mL (95% CI 82.7-93.8). The highest postoperative temperature was 37.8 +/- 0.3 degrees C, and the postoperative morbidity was 5.7% (32/566). Number of days to the return of bowel movement was 1.9 +/- 0.5d and in hospital stay after surgery was 7.7 +/- 2.5d. Complications included 2 instances of subcutaneous emphysema, 1 of vaginal bleeding, and 3 of mild intestinal obstruction. At a median of 26.3 months (range 6-69 months) of follow-up, the rate of myoma recurrence was 3.0% (15/517), uterus volume reduction was 48.9%, and correction of menstruation abnormality was 97.1% (502/517). Laparoscopic uterine artery occlusion before myomectomy can expand myomectomy indications with better results. PMID:18439509

    Twenty-two samples, taken from eight pathological proved uterine myoma patients, were embedded in paraffin and cut into slices of identical thickness (4.0 μm). After deparaffinization, washing and drying, the slices of myomal tissue and their neighboring myometrial tissue were bombarded by 2.0 MeV proton beams from a 3 MV Van de Graaff accelerator. The induced characteristic X-rays were then detected and analyzed using a HPGe detector system. The absolute concentrations of trace elements contained in tumors and normal tissues of human myomal uterus were determined, in reference to a known concentration of doped yttrium. Significant correlations between the concentration of elements, both in tumors and in normal tissues, were found.

    Eighteen patients with endometriosis or uterine myoma underwent MRI before and after conservative treatment with Danazol (400 mg/day) or Buserelin (900 {mu}g/day) to examine pathological changes. Of 8 patients with endometrial chocolate cyst, 7 patients were given Dazazol for 3 to 7 months, in whom high signal intensity indicative of mass tended to decrease after chemotherapy especially on T2-weighted images. In addition, the area of cyst was reduced by 31% to 100%. In the remaining one patient receiving Buserelin for 8 months, the reduction rate of cyst was 31%. Ten patients with adenomyosis were classified into the group given Danazol for 5 to 15 months (n=4) and the group given Buserelin for 3 to 8 months (n=6). Low intensity area was decreased by 9% to 25% in the Danazol group and by 20% to 69% in the Buserelin group. Uterine area was reduced by 10% to 32% in the Danazol group and by 4.5% to 51% in the Buserelin group. MRI was helpful in the management of these diseases during conservative treatment. (N.K.).

  11. Uterine myomas in pregnancy, childbirth and puerperium

    Full Text Available Fibroids are the most common benign tumors of the genital organs of women in reproductive age. Achieving reproductive function later in life, with more frequent use of assisted reproductive technologies, leads to an increased number of pregnancies complicated with fibroids. Their size may change during pregnancy, but the changes are mostly individual. Most fibroids stop growing or decline during the puerperium. The effect of fibroids on pregnancy depends on their number, size and location. The mechanisms bringing about perinatal complications are not fully understood. Fibroids during pregnancy can cause many perinatal complications, such as bleeding in pregnancy, miscarriage, pain due to red degeneration, malpresentation, preterm labor, premature rupture of membranes, placental abruption and obstruction of delivery and are associated with higher incidence of cesarean section, operative vaginal delivery, uterine atony and postpartum hemorrhage. Postpartum hysterectomy in these women is also more likely than in general population. Postpartum infections are more common in patients with fibroids, and myomas may also cause retained placenta. The most common cause of neonatal morbidity is prematurity, due to pregnancy ending in an earlier gestational age. Monitoring of pregnancies complicated with fibroids is essentially indistinguishable from monitoring normal pregnancies. Therapy includes only bed rest and observation, symptomatic therapy in case of pain and intensive fetal surveillance, and surgery in the acute situations.

    Myomas are the most common benign tumors of the genital organs in women of childbearing age, causing significant morbidity and impairing their quality of life. In our investigation, we have reviewed the epidemiological data related to the development of myomas in order to homogenize the current data. Therefore, a MEDLINE and PubMed search, for the years 1990-2013, was conducted using a combination of keywords, such as "myoma," "leiomyoma," "fibroids," "myomectomy," "lifestyle," "cigarette," "alcohol," "vitamins," "diet," and "hysterectomy". Randomized controlled studies were selected based upon the authors' estimation. Peer-reviewed articles examining myomas were sorted by their relevance and included in this research. Additional articles were also identified from the references of the retrieved papers and included according to authors' estimation. Many epidemiologic factors are linked to the development of myomas; however, many are not yet fully understood. These factors include age, race, heritage, reproductive factors, sex hormones, obesity, lifestyle (diet, caffeine and alcohol consumption, smoking, physical activity and stress), environmental and other influences, such as hypertension and infection. Some of the epidemiological data is conflicting. Thus, more research is needed to understand all the risk factors that contribute to myoma formation and how they exactly influence their onset and growth. PMID:26985330

    2014-03-01

    Full Text Available Background. Uterine leiomyoma and endometrial hyperplasia are commonly found disorders because of quite similar pathogenic pathways associated with action of sex steroids such as estradiol and progesterone. The gold standard of treatment of combination of uterine leiomyoma and endometrial hyperplasia is myomectomy with further prescription of gestagens. Objective. Histological and immunohistochemical evaluation of leiomyoma and endometrial tissue in patients with uterine leiomyoma and endometrial hyperplasia. Methods. In this study histological and immunohistochemical analysis of leiomyoma and endometrium samples were conducted in 30 patients with uterine leiomyoma and endometrial hyperplasia. Further evaluation with transvaginal ultrasound end endometrial biopsy was conducted in 6 and 12 months after surgery. Results. In women with combined endometrial hyperplasia and uterine leiomyoma there is an increased risk of myoma relapse (23.3% and treatment failure of endometrial hyperplasia (36.7% after traditional treatment with gestagens. Among 7 patients with leiomyoma recurrence there was persistence of endometrial hyperplasia what was associated with increased proliferation, angiogenesis and decreased apoptosis. Conclusion. During a comprehensive immunohistochemical study of endometrial biopsies and uterine leiomyoma in women with histologically verified uterine leiomyoma and endometrial hyperplasia common immunohistochemical features had been identified such as increased expression of ki-67 and VEGF and bcl-2. It was proposed that traditional scheme using derivatives of progesterone should be avoided in such patients. In order to optimize treatment outcomes in women with such findings proposed treatment of choice should be drugs with severe suppressive action on proliferation, angiogenesis with simultaneous stimulating action on apoptosis. Drug of choice in such case should be GnRH agonist what should be assessed in future research. Citation

  15. Uterine development and endometrial programming.

    Bartol, F F; Wiley, A A; Bagnell, C A

    2006-01-01

    Structural patterning and functional programming of uterine tissues are mechanistically coupled. These processes ensure anteroposterior differentiation of uterine tissues from adjacent segments of the developing female reproductive tract (FRT) and radial patterning that establishes uterine-specific histoarchitecture and functionality. Uterine organogenesis begins prenatally and is completed postnatally. Genes required for FRT development include Pax2, Lim1 and Emx2, genes in the abdominal-B Hoxa cluster, and members of both Wnt and Hedgehog (Hh) gene families. Disruption of morphoregulatory gene expression patterns can prevent FRT development entirely or compromise uterine organogenesis specifically. Oestrogen receptor-alpha (ER) -dependent events associated with development of the neonatal porcine uterus can be altered by administration of oestrogen (E) or relaxin (RLX). Expression of the RLX receptor is detectable in porcine endometrium at birth, before onset of ER expression and uterine gland genesis. Uterotrophic effects of both E and RLX can be inhibited with the ER antagonist ICl 182,780, indicating that RLX may act via crosstalk with the ER system in neonatal tissues. Exposure of neonatal gilts to E alters temporospatial patterns of Hh, Wnt and Hoxa expression in the uterine wall. Oestrogen given for two weeks from birth produced hypoplastic adult porcine uteri that were less responsive to periattachment conceptus signals as reflected by reduced growth response and luminal fluid protein accumulation, altered endometrial gene expression, and reduced capacity for conceptus support. Data reinforce the concept that factors affecting signalling events in uterine tissues that produce changes in morphoregulatory gene expression patterns during critical organisational periods can alter the developmental trajectory of the uterus with lasting consequences. Thus, uterine tissues can be programmed epigenetically for success or failure during perinatal life. PMID

  16. Deep venous thrombosis due to massive compression by uterine myoma

    Aleksandra Brucka

    2010-10-01

    Full Text Available A 42-year-old woman, gravida 3, para 3 was admitted to hospital because of painful oedema of her right lower extremity. Initial physical examination revealed a gross, firm tumour filling the entire peritoneal cavity. Doppler ultrasound scan revealed a thrombus in the right common iliac vein, extending to the right femur and popliteal veins, and partially into the calf deep vein. Computed tomography confirmed the existence of an abdominal tumour probably deriving from the genital organs and the presence of a thrombus in the said veins.The patient underwent hysterectomy where a myomatous uterine was removed. She was put on subcutaneous enoxaparine and compressive therapy of the lower extremities. Such symptoms as pain and oedema receded. Control Doppler scan showed fibrinolysis, partial organization of the thrombus and final vein recanalisation. After exclusion of other risk factors of deep vein thrombosis apart from stasis, we conclude that the described pathology was the effect of compression of regional pelvic structures by a uterine myoma.

  17. Non-puerperal uterine inversion due to submucous myoma in a young woman: a case report

    Perquin Denise

    2010-01-01

    Full Text Available Abstract Introduction Inversion of the uterus is an uncommon complication of the puerperium and it is an even rarer complication of the non-puerperal period. A submucous myoma is mostly the cause of the non-puerperal inversion but diagnosis can be difficult. In young women, non-puerperal uterine inversion is likely associated with a malignancy. Case presentation A 19-year-old nulliparous woman presented with abnormal vaginal bleeding, dysmenorrhoea, and a large mass protruding from her cervix. The mass was interpreted as a prolapsed pedunculated submucosal myoma. After extirpation of the mass by clamping and twisting its pedicle, a laparotomy was required under suspicion of a uterine rupture. The diagnosis was confirmed and the patient's uterus could be preserved. Pathological examination revealed a submucous myoma. The uterine inversion happened when the uterus retracted to expel the submucous myoma with fundal attachment. By extirpating the stalk the fundus was also resected, causing a uterine rupture. Conclusion We report a case of non-puerperal uterine inversion associated with a benign submucous myoma. Non-puerperal uterine inversion is very uncommon in women of reproductive age and is usually caused by a malignant tumour. However, uterine-sparing surgery should be attempted in young women until the final pathology is known.

  18. Body weight gain during adulthood and uterine myomas: Pró-Saúde Study

    2015-01-01

    Full Text Available This study intended to investigate whether body weight gain during adulthood is associated with uterine myomas. 1,560 subjects were evaluated in a Pró-Saúde Study. Weight gain was evaluated in a continuous fashion and also in quintiles. Odds ratios and 95% confidence intervals were estimated through logistic regression models that were adjusted for education levels, color/race, body mass indices at age 20, age of menarche, parity, use of oral contraceptive methods, smoking, health insurance, and the Papanicolaou tests. No relevant differences were observed regarding the presence of uterine myomas among weight gain quintiles in that studied population.

  19. Receptors of Hypothalamic-Pituitary-Ovarian-Axis Hormone in Uterine Myomas

    2014-01-01

    Full Text Available In this study the expression of GnRH, FSH, LH, ER-α, ER-β, and PR receptors was examined in uterine myomas of women in reproductive and perimenopausal age. In cases of GnRH and tropic hormones a membranous and cytoplasmic immunohistochemical reaction was detected, in cases of ER-α and PR the reaction was located in cell nucleus, and in the case of ER-β it manifested also a cytoplasmic location. In some of the examined cases the expression was detected in endometrium, myocytes, and endothelium of blood vessels, in uterine glands and myoma cells. In myometrium the level of GnRH and LH receptors increases with age, whereas the level of progesterone and both estrogen receptors decreases. In myomas of women in reproductive age, independently of their size, expression of GnRH, FSH, and LH receptors was more pronounced than in myometrium. In women of perimenopausal age, independently of myoma size, expression of LH and estrogen α receptors was higher while expression of GnRH receptors was lower than in myometrium. FSH receptor expression was not observed. Expression of estrogen receptor β was not affected by age of the woman or size of myoma. Analysis of obtained results indicates on existing in small myomas local feedback axis between GnRH-LH-progesterone.

  20. Prevalence of uterine myoma detected by ultrasound examination in the atomic bomb survivors

    Benign tumors of several organs have been demonstrated to occur as late effects of atomic bomb exposure, and a recent addition to the list of affected organs in the uterus. The increased incidence of uterine myoma noted in Radiation Effects Research Foundation (REFR) Adult Health Study Report 7, however, was based on self-reported information, optional gynecological examination and patient-requested ultrasound examination. Thus the possibility of dose-related bias in case detection was a serious concern. Therefore, the relationship between the prevalence of uterine myoma and dose to the uterus was examined after excluding as much bias as possible by asking all women who had undergone biennial examinations from December 1991 through December 1993 to undergo ultrasound examinations. Among 2506 female participants in Hiroshima, the uterus was visualized by ultrasound examination in 1190, and 238 were found to have uterine nodules. Multiple logistic analysis using Dosimetry System 1986 uterine doses revealed a significant dose response for the prevalence of uterine nodules. The odds ratio at 1 Gy was 1.61 (95% confidence interval: 1.12-2.31). It is unlikely that the observed relationship after adjusting for bladder filling, volume of the uterus, age and menopause status was the result of dose-related bias. These results support previous findings at RERF and provide further evidence that radiation exposure is one of the factors associated with uterine myoma. 28 refs., 3 figs., 4 tabs

  1. Evaluation on the safety of transcatheter uterine artery embolization for uterine myoma

    Objective: To observe complications of transcatheter uterine artery embolization (TUAE) for uterine fibroids and to evaluate its long-term safety. Methods: One hundred and ninety-eight women with uterine fibroids were treated by TUAE. The bilateral TUAE were performed using lipiodol-pingyangmycineemulsion (LPE) and gelatin sponge particles in 186 women. Among them, 138 patients were followed up for 1 to 3 year and complications were observed. Results: Complications included ecchymosis and ulceration on buttock (n=1); ulcer of labia minora (n=1); urinary retention (n=12); urinary tract infection (n=1); expelling of necrotic fibroids via vagina (n=5); secondary infection of chocolate cyst of ovary (n=1); increasing in endometrial thickness and calcification (n=1) and amenorrhea (n=2). Conclusion: TUAE is a treatment with long-term safety, while severe complications or sequelae may occur to a few patients, so strict indication should be insisted in patient selection. (authors)

    2015-09-01

    Full Text Available Background. Uterine leiomyoma is one of the most common benign tumors of the female genital organs. The main conservative treatment of leiomyoma is progesterone receptor blockers that suppress myoma growth and may lead to its regression. Objective. To study the immunohistochemical features of myoma tissue in patients with uterine leiomyoma after treatment with selective progesterone modulator - ulipristal acetate. Methods. Leiomyoma tissue obtained from 9 patients after ulipristal acetate treatment were investigated. Group for comparison - leiomyoma from patients without hormonal therapy. Immunohistochemical study of progesterone and estrogen receptors, proliferative activity marker Ki-67 and inhibitor of apoptosis Bcl-2 was performed. Results. In the group of patients without preoperative hormonal treatment progesterone receptors were expressed in 76,4±6,8% of the nuclei, estrogen receptors - in 32,8±2,6%. In the group of patients after treatment with ulipristal acetate there was a significant decrease of progesterone receptor expression – 36,8±1,28% (p 0,05 . Bcl-2 in the control group was found in 65,4±7,2% cells, in leiomyoma after treatment there was a significant decrease of bcl-2 – 42,6±3,2% (p <0, 05. In leiomyomas without hormonal treatment Ki-67 was determined in 11,8% of the nuclei of smooth muscle cells, and in leiomyomas after ulipristal acetate – in 7,2% leiomyoma cells. Conclusions. In patients after three months of ulipristal acetate treatment there was a significant decrease of expression of progesterone receptor, bcl-2, and Ki-67. Taken together these data evidence reduced action of progesterone on leiomyoma cells, induction of apoptosis and decreased proliferation processes that may cause involution of fibroids.

  5. Focused ultrasound for treatment of uterine myoma: From experimental model to clinical practice

    Terzić Milan

    2008-01-01

    Full Text Available It is well known that focused ultrasound has a biologic effect on tissue. High intensity focused ultrasound (HIFU on a small target area raises the temperature of the tissue enough to denaturate proteins and cause irreversible cell damage. The tight focus of the ultrasound energy allows delivery of the intended dose to a very precise location. The resulting coagulation necrosis is relatively painless. The application of this method in the human clinical setting has required pilot studies on an animal model. Although the treatment had a high success rate, there was a significant percentage of complications, mainly attributed to the technical drawbacks of the procedure. Therefore, this method has been modified for use in humans, and the HIFU is now guided, monitored and controlled by magnetic resonance imaging (MRI. In October 2004, Food and Drug Adiministration (FDA approved MRI guided focused ultrasound treatment of uterine fibroids in humans. Since then, successful treatment of uterine myomas by HIFU has been performed in thousands of women.

  7. Magnetic Resonance-Guided High-Intensity Focused Ultrasound (MR-HIFU) in Treatment of Symptomatic Uterine Myomas

    Magnetic Resonance-guided High-Intensity Focused Ultrasound (MR-HIFU) is a noninvasive technique for ablation therapy for uterine myomas, where focused ultrasound energy beam generates localized high temperature in the selected area and coagulates chosen tissue, leaving the skin and tissues in between unharmed. Magnetic resonance imaging enables accurate targeting for HIFU as well as temperature monitoring during treatment. MR guidance with 3D anatomical imaging provides reference data for treatment planning, while real-time temperature monitoring aids in controlling ablation process. This review provides basic information regarding methodology, clinical indications for this kind of treatment, expected outcome and patient management during MR-HIFU procedure. The aim of this work is to introduce a new, noninvasive treatment method for uterine leiomyomas and to present a comparison with other currently used methods

    Myomas are the most common disorder of the female genital organs, occurring more frequently throughout women's reproductive years. Myomas are a major health issue all over the world. They develop as a monoclonal tumor from cells influenced by ovarian steroids, and mediated by surrounding myometrial cells by paracrine mechanisms. During its growth, a myoma compresses the surrounding tissue, causing the formation of a pseudocapsule, encapsulating the myoma. The mechanical properties of myomas are a key factor which can contribute to their growth. While myomas are essentially rigid, their pseudocapsule is more elastic, and this allows uterine adaptation to the growing myoma. Hence, the pseudocapsule induces displacement on the myometrium, which is not destructive since the integrity and contractility of uterine structure is maintained. Extensive research conducted on the myoma and its pseudocapsule has produced important data. Scientific research is still trying to clarify some of the evidence regarding the influence of myomas on infertility, especially in the case of intramural myomas. During fertility-sparing myoma surgery, data suggest that during myoma removal the pseudocapsule should be preserved. However, unsolved issues still exist on the cesarean myomectomy technique, since the age of pregnancy has been increasing in the new millennium, so patients present with myomas which should be removed before and during the cesarean section, or prior to applying for medically-assisted reproduction.

  9. Pathologies of the uterine endometrial cavity: usual and unusual manifestations and pitfalls on magnetic resonance imaging

    The endometrial cavity may demonstrate various imaging manifestations such as normal, reactive, inflammatory, and benign and malignant neoplasms. We evaluated usual and unusual magnetic resonance imaging (MRI) findings of the uterine endometrial cavity, and described the diagnostic clues to differential diagnoses. Surgically proven pathologies of the uterine endometrial cavity were evaluated retrospectively with pathologic correlation. The pathologies included benign endometrial neoplasms such as endometrial hyperplasia and polyp, malignant endometrial neoplasms such as endometrial carcinoma and carcinosarcoma, endometrial-myometrial neoplasm such as endometrial stromal sarcoma, pregnancy-related lesions in the endometrial cavity such as gestational trophoblastic diseases (hydatidiform mole, invasive mole and choriocarcinoma) and placental polyp, myometrial lesions simulating endometrial lesions such as submucosal leiomyoma and some adenomyosis, endometrial neoplasms simulating myometrial lesions such as adenomyomatous polyp and endometrial lesions arising in the hemicavity of a septate/bicornate uterus, and fluid collections in the uterine cavity (hydro/hemato/pyometra). It is important to recognize various imaging findings in these diseases, in order to make a correct preoperative diagnosis. (orig.)

  11. The impact of low-volume uterine lavage on endometrial biopsy classification.

    Linton, J K; Sertich, P L

    2016-09-01

    In the mare, the low-volume uterine lavage technique allows for bacterial sampling of the entire uterine lumen and is usually performed after obtaining the traditional double-guarded endometrial swab for aerobic culture and cytology and before procurement of an endometrial biopsy sample during a breeding soundness examination. The purpose of this study was to explore the potential effects of the low-volume lavage on the endometrial biopsy classification and polymorphonuclear cell (PMNs) infiltration in the context of a breeding soundness examination. Fourteen light horse mares of mixed breed, age 7 to 21 years, with known reproductive history, were included in the study, matched by age and reproductive history, and then divided into treatment and control groups. Transrectal palpation and ultrasonography, endometrial swabbing, and the first endometrial biopsy were performed in all mares. Low-volume uterine lavage was performed in the treatment group but not the control group. After either the lavage or a 15-minute rest, a second endometrial biopsy was obtained from both the control and treatment groups. Endometrial swabs and effluent from the low-volume lavages were submitted for aerobic culture and sensitivity. Biopsy samples were fixed in Bouin's solution for 24 hours, processed, stained with hematoxylin and eosin, and then viewed under bright light microscopy. Additional staining with anti-neutrophil elastase antibody (ab68672) was performed for indirect immunohistochemistry. All samples were interpreted by a blinded observer. When the first (pre-uterine lavage) and second (post-uterine lavage) biopsies were compared using a mixed-effects logistic regression, there was no difference in endometrial biopsy classification (P = 0.74), presence of PMNs in blood vessels (P = 0.728), or infiltration of PMNs in the tissue (P = 0.934) between the treatment and control groups. In this study, the low-volume uterine lavage did not affect the endometrial biopsy

  12. Parasitic myoma after supracervical laparoscopic histerectomy

    Maurício Paulo Angelo Mieli

    2013-06-01

    Full Text Available Parasitic myoma is a condition defined as a myoma of extrauterine nourishing. It may occur spontaneously or as a consequence of surgical iatrogeny, after myomectomy or videolaparoscopic supracervical hysterectomy, due to remaining residues of uterine tissue fragments in the pelvic cavity after morcellation. The authors describe two cases in which the patients were submitted to videolaparoscopic supracervical hysterectomy and uterine body removal through morcellation. The sites of development of the parasitic myomas were next to the cervix stump in Case 1, and next to the right round ligament in Case 2. These parasitic myomas were removed by videolaparoscopy. After myomectomies or videolaparoscopic supracervical hysterectomies followed by uterine fragments removal from the pelvic cavity through morcellation, meticulous searching for residues or fragments of uterine tissue is mandatory to prevent the occurrence of parasitic myomas.

    To evaluate the effectiveness of an additional transdermal fentanyl patch compared to intravenous analgesics in pain control during the 24-hour period following uterine artery embolization (UAE) for myoma and adenomyosis. Between September 2009 and August 2010, 42 patients underwent UAE for myoma or adenomyosis. Of these, 21 received an intravenous opioid (pethidine) and a nonsteroidal anti-inflammatory drug (group A), and 21 received an additional transdermal fentanyl patch (group B). Pain perception levels were established verbally on a 0-10 scale during the 24-hour period following UAE. Differences in pain trends, mean dose of intravenous pethidine, and adverse effects were compared between the two groups. Pain perception was most severe at 6 hours after UAE and the mean pain level of group B at that time was 6.3 {+-} 0.7, which was significantly lower than that of group A, 8.2 {+-} 0.7 (p<0.05). The mean dose of intravenous pethidine was 114.3 {+-} 59.5 mg in group A and 90.5 {+-} 49.0 mg in group B, while the incidence of nausea was 67% in group A and 77% in group B. In both cases, the differences were not significantly different (p>0.05), and no evidence of respiratory distress was demonstrated. The addition of a transdermal fentanyl patch to intravenous analgesics is effective in reducing post-embolization pain during the 24-hour period after UAE.

The addition of a transdermal fentanyl patch to intravenous analgesics is effective in reducing post-embolization pain during the 24-hour period after UAE.

  16. Uterine epithelial cell proliferation and endometrial hyperplasia: evidence from a mouse model.

    Gao, Yang; Li, Shu; Li, Qinglei

    2014-08-01

    In the uterus, epithelial cell proliferation changes during the estrous cycle and pregnancy. Uncontrolled epithelial cell proliferation results in implantation failure and/or cancer development. Transforming growth factor-β (TGF-β) signaling is a fundamental regulator of diverse biological processes and is indispensable for multiple reproductive functions. However, the in vivo role of TGF-β signaling in uterine epithelial cells remains poorly defined. We have shown that in the uterus, conditional deletion of the Type 1 receptor for TGF-β (Tgfbr1) using anti-Müllerian hormone receptor type 2 (Amhr2) Cre leads to myometrial defects. Here, we describe enhanced epithelial cell proliferation by immunostaining of Ki67 in the uteri of these mice. The aberration culminated in endometrial hyperplasia in aged females. To exclude the potential influence of ovarian steroid hormones, the proliferative status of uterine epithelial cells was assessed following ovariectomy. Increased uterine epithelial cell proliferation was also revealed in ovariectomized Tgfbr1 Amhr2-Cre conditional knockout mice. We further demonstrated that transcript levels for fibroblast growth factor 10 (Fgf10) were markedly up-regulated in Tgfbr1 Amhr2-Cre conditional knockout uteri. Consistently, treatment of primary uterine stromal cells with TGF-β1 significantly reduced Fgf10 mRNA expression. Thus, our findings suggest a potential involvement of TGFBR1-mediated signaling in the regulation of uterine epithelial cell proliferation, and provide genetic evidence supporting the role of uterine epithelial cell proliferation in the pathogenesis of endometrial hyperplasia.

  17. Study of the Impact of Uterine Artery Embolization (UAE) on Endometrial Microvessel Density (MVD) and Angiogenesis

    PurposeTo investigate the influence of uterine artery embolization (UAE) on endometrial microvessel density (MVD) and angiogenesis.MethodsSixty female guinea pigs were divided into two groups, the control group (n = 15) and the UAE treatment group (n = 45). In the UAE group, tris–acryl gelatin microspheres were used to generate embolization. Animals were further divided into three subgroups, A1, A2, and A3 (n = 15 for each subgroup), with uterine specimens collected at 7–15, 16–30, and 31–45 days after UAE, respectively. Immunostaining for factor VIII and CD105 was performed to identify total endometrial MVD (MVDFVIII) and CD105-positive angiogenesis (MVDCD105) at the indicated time points after UAE.ResultsQuantitative analysis revealed that MVDFVIII significantly decreased in the A1 (11.40 ± 2.76, p CD105-positive angiogenesis in the A1 group (9.33 ± 2.37, p CD105 value returned to normal in the A3 group (8.07 ± 1.97).ConclusionUAE caused a temporal decrease in endometrial MVD that reversed over time as a result of the increase of CD105-positive angiogenesis. Although the UAE-induced reduction of endometrial MVD was reversible, its long-term effect on endometrial receptivity still needs further study

    1999-12-01

    We investigated 258 cases of uterine endometrial cancer diagnosed and treated from 1980 through 1997 at our institution. Disease outcome, adjuvant therapies, and histologic features were analyzed. Patients' ages ranged from 20 to 90 years (mean, 57.0{+-}10.8 years). The 5-year survival rates were 97.5% for stage I disease, 81.7% for stage II disease, 69.8% for stage III disease, and 0% for stage IV disease. Patients with stage III disease who received both chemotherapy and radiation therapy as adjuvant therapies survive slightly, but not significantly, longer than did patients who received chemotherapy alone or radiation alone or no adjuvant therapy. The 136 patients (59.9%) with well-differentiated (G1) endometrioid carcinomas were significantly younger (mean age, 55.9{+-}10.3 years) than the 58 (25.6%) patients with moderately differentiated carcinomas (G2, 59.9{+-}10.4 years, p=0.01) and the 33 patients (14.5%) with poorly differentiated (G3, 59.9{+-}8.2 years, p=0.04) endometrioid carcinomas. The 60 cases of endometrial carcinoma from 1994 through 1997 were examined to determine whether endometrial hyperplasia and adenocarcinoma coexist. Endometrial hyperplasia was present in 23 (38%) of the 60 cases. The patients with both endometrial hyperplasia and adenocarcinoma were significantly younger (mean age, 47.7{+-}10.9 years) than the patients with endometrial adenocarcinoma alone (mean age, 59.5{+-}9.5 years, p<0.001).

    After parturition, the uterus undergoes marked remodelling during involution; however, little is known of the hormonal, cellular and molecular mechanisms that regulate this process. The working hypothesis used in this study is that return of the ovine uterus to a non-pregnant state involves termination of a hormonal servomechanism that regulates endometrial gland morphogenesis and function during pregnancy. Suffolk ewes were ovariohysterectomized on postpartum days 1, 7, 14 or 28. Serum concentrations of oestradiol were high at parturition, declined to postpartum day 4, peaked on postpartum day 6, and then declined and remained low thereafter. Progesterone was undetectable in plasma from ewes post partum. Uterine wet mass and horn length decreased after postpartum day 1, but ovarian mass did not change. Residual placental cotyledons were present in the maternal caruncles on postpartum days 1 and 7 and were extruded by postpartum day 14 as plaques that were resorbed by postpartum day 28. The width of the total endometrium, stratum compactum, stratum spongiosum and myometrium, as well as endometrial gland density, decreased after parturition. Most apoptotic cells in the involuting uterus were large, vacuolated and located between the endometrial glandular epithelial cells on postpartum days 1 and 7. Immunofluorescence analyses identified both T and B cells within the glandular epithelium on postpartum day 1. Cell proliferation was detected in the luminal epithelium and glandular epithelium on postpartum days 1 and 7. On postpartum day 1, expression of oestrogen receptor alpha (ERalpha) was not detected in luminal epithelium and was low in glandular epithelium, but ERalpha was present in epithelia thereafter. Progesterone receptor (PR) protein was not detected in endometrial epithelia on postpartum day 1, but was detected in the glandular epithelium thereafter. Between postpartum days 1 and 7, ERalpha and PR protein increased substantially in the endometrial glandular

    2015-06-01

    Full Text Available Background: Abnormal Uterine Bleeding (AUB is referred as bleeding outside of normal menstruation pattern and it is the most common gynecological problem for women of all ages. This study was evaluated the correlation of menstrual bleeding patterns and endometrial histopathological findings in perimenopausal women. Methods: This study was done on perimenopausal aged women presented with AUB for the last 6 months at a gynecology clinic of a tertiary medical center. Only the patients with isolated endometrial causes of AUB were selected for study. A total of 313 cases were included in the study. Abnormal bleeding patterns of the patients were recorded and endometrial sampling was performed to all women. AUB was classified as menorrhagia, metrorrhagia, menometrorrhagia, polymenorrhea, intermenstrual bleeding, and histopathological findings were classified as Proliferative Endometrium (PE, Secretory Endometrium (SE, Disordered Proliferative Pattern (DPP, Endometrial Polyp (EP, Chronic Endometritis (CE, Endometrial Hyperplasia (EH, and Endometrial Adenocarcinoma (CA. Results: The most common bleeding pattern was menorrhagia (45.0% and the most common histopathological finding was PE+SE (52.0% in our study. PE+SE and endometrial hyperplasia without atypia were found more common in menorrhagia group. The most histopathological findings were found PE+SE in menometrorrhagia and polymenorrhea group (P 0.05. Conclusions: We concluded that although menometrorrhagia and polymenorrhea were significantly more associated with PE+SE, intermenstrual bleeding was significantly more associated with EP and CE. It is noteworthy that endometrial hyperplasia without atypia is significantly higher in patients with menorrhagia which is the most common abnormal bleeding pattern in perimenopausal aged women.

    2006-06-01

    Full Text Available Today, there still exists a controversial issue, as to the high incidence of early embryonic death in mares, mated on the first post partum oestrus. The purpose of this study was first, to determine the post partum period of uterine involution in fine pace Colombian mares using endometrial cytology and ultra sonograph. Secondly, to determine the relation between the neutrophil percentages found in cytology and the echogenicity of accumulated intrauterine fluid during the first 30 post partum days. Twenty (n=20 mares were examined beginning on the 6th post partum day and on alternate days, up to the 30th day. All subjects were grazing Kikuyo grass (Pennisetum clandestinum at la Sabana de Bogotá, 2.600 meters over sea level, 4 º north latitude and with an average temperature of 13 º C. From the 3rd postpartum day, all 20 mares were exposed to 2 healthy stallions, to establish their heat behaviour. Ten of them, following complete randomization, were inseminated on the first postpartum heat, while the others were inseminated on the second post partum heat. Genital examination was carried out by a technician, who did not know the reproductive history of any of the experimental mares. Examinations included rectal palpation, ultra sonograph (Pie Medical 480, linear array, 5 MHz, vaginal swabs and endometrial cytology. Uterine dimension was recorded by rectal palpation and ultra sonograph, it was included the uterine horn dimensions (tip, middle, and corporo-cornual junction of previously gravid and non gravid uterus. Intrauterine fluid detection was performed by the use of an echogenicity scale. Ovaric structures were recorded (preovulatory follicles and ovulation. Pregnancy diagnosis was performed on day 15 post ovulation and then confirmed on day 40. Endometrial cytology samples were taken from uterus after the perineal area was disinfected using non covered isopos with a Pollanski speculum. Smears specimens were fixed with metil alcohol for 15

  2. Current approaches to the treatment of endometrial hyperplasia in women with uterine leiomyoma

    Potapov V.A.

    2014-09-01

    Full Text Available The study involved 155 women, of which 30 healthy women were in the control group. 125 women with uterine leiomyomas and endometrial hyperplasia constituted the main groups. In all women with uterine leiomyoma myomectomy was performed. Further treatment included randomized study of a new regimen of GnRH agonists together with COCs after myomectomy using comparison techniques: monotherapy with a-GnRH, progestins (dydrogesterone or COCs. The treatment using different medication regimens of endometrial hyperplasia after myomectomy convincingly demonstrated significantly greater efficacy of GnRH-a and COCs com¬bination in reducing frequency of symptoms of these diseases, volume of menstrual blood loss and improvement quality of life through the entire observation period. Greater efficacy of COCs and a-GnRH combination, to our opinion, is associated with a greater degree of suppression of cell proliferation and angiogenesis as a result of local (COCs, and systemic effects (a-GnRH.Thus, the proposed method of adjuvant therapy after myomectomy for women with associated endometrial hyperplasia has significant clinical benefits with minimal impact on bone mineral density and other menopausal signs caused by a-GnRH monotherapy.

    Doppler ultrasound is a useful diagnosis tool to evaluate uterine blood flow in different canine reproductive states. The aim of this study was to describe and compare uterine blood flow in bitches suffering from cystic endometrial hyperplasia (CEH) and CEH-pyometra complex (CEH-P). Ninety diestrous bitches were clinically, hematologically, and ultrasonographically classified into four groups: (1) clinical signs, leukocytosis, CEH, and uterine luminal contents (CEH-P, n = 31); (2) asymptomatic bitches with CEH and uterine contents (CEH-C, n = 15); (3) asymptomatic bitches with CEH without uterine contents (CEH, n = 16); and (4) normal diestrous bitches (ND, n = 28). The widest cross-sectional diameter and uterine wall thickness (W) of uterine horns were measured using two-dimensional ultrasound. Peak systolic velocity and end diastolic velocity of uterine arteries were measured by Doppler ultrasound in all the bitches. Peak systolic velocity and end diastolic velocity were higher in CEH-P than in CEH-C, CEH, and ND (P  0.1). Conversely, resistance index (RI) reported lower values in CEH-P than that in the other three groups (P  0.1). When all the bitches were considered, correlation between RI and cross-sectional diameter was r = -0.69 (P  0.1). It is concluded that the uterine artery blood flow velocity of bitches suffering from pyometra was higher, not only from normal bitches, but also from females with endometrial hyperplasia. Furthermore, endometrial hyperplasia, accompanied or not by luminal contents, had a higher blood flow velocity than normal uterus. Hemodynamic parameters appear as useful markers to differentiate uterine pathologic conditions. PMID:26810829

    2016-05-01

    Uterine papillary serous carcinoma (UPSC) represents 10% of endometrial carcinomas. Significant number of patients initially present with extrauterine disease. The role of adjuvant treatment in low stage, especially polyp-confined UPSC is controversial. This multi-institutional study evaluated the significance of positive pelvic washing (PW) and adjuvant treatment on disease recurrence in a setting of endometrial polyp-confined UPSC. Surgical pathology files from 3 institutions were searched for cases of endometrial polyp-confined UPSC. Following histologic review, cases were clinically staged as Stage I, without myoinvasion or lymphovascular invasion. Clinicopathologic characteristics, results of PW, and type of adjuvant therapy were recorded. Statistical analysis using the Kaplan-Meier method for survival and Fisher exact test were performed. Thirty-three patients were included in the study. All patients were diagnosed with polyp-confined UPSC. The size of the polyp ranged from 0.3 to 4.3 cm. PW was positive for tumor cells in 8/33 (24%) patients. Twenty-two patients (66.6%) received some type of adjuvant treatment. Six patients (18%) developed recurrent disease. There was no significant difference in disease-free survival in the patients receiving adjuvant treatment versus not (P=0.375). However, there was significant association (P=0.0013) between positive PW and disease recurrence. Data are conflicting whether positive PW affects prognosis in low-stage endometrial carcinomas. Our study showed that in UPSC, malignant cells can be present in PW without lymphovascular invasion or myoinvasion and may have negative prognostic implication. Our data also reflect the controversies in the role of adjuvant treatment in endometrium-confined UPSC. PMID:26535985

  9. Nursing for 48 hours from birth supports porcine uterine gland development and endometrial cell compartment-specific gene expression.

    Miller, Dori J; Wiley, Anne A; Chen, Joseph C; Bagnell, Carol A; Bartol, Frank F

    2013-01-01

    The first 2 wk of neonatal life constitute a critical period for estrogen receptor alpha (ESR1)-dependent uterine adenogenesis in the pig. A relaxin receptor (RXFP1)-mediated, lactocrine-driven mechanism was proposed to explain how nursing could regulate endometrial ESR1 and related gene expression events associated with adenogenesis in the porcine neonate during this period. To determine effects of nursing on endometrial morphogenesis and cell compartment-specific gene expression, gilts (n = 6-8/group) were assigned at birth to be either 1) nursed ad libitum for 48 h, 2) gavage fed milk replacer for 48 h, 3) nursed ad libitum to Postnatal Day (PND) 14, or 4) gavage fed milk replacer for 48 h followed by ad libitum nursing to PND 14. Uteri were collected on PND 2 or PND 14. Endometrial histoarchitecture and both ESR1 and proliferating cell nuclear antigen (PCNA) labeling indexes (LIs) were evaluated. Laser microdissection was used to capture epithelium and stroma to evaluate treatment effects on cell compartment-specific ESR1, VEGFA, and RXFP1 expression. Imposition of a lactocrine-null state by milk replacer feeding for 48 h from birth retarded endometrial development and adenogenesis. Effects of replacer feeding, evident by PND 2, were marked by PND 14 when endometrial thickness, glandularity, and gland depth were reduced. Consistently, in lactocrine-null gilts, PCNA LI was reduced in glandular epithelium (GE) and stroma on PND 14, when epithelial ESR1 expression and ESR1 LI in GE were reduced and stromal VEGFA and RXFP1 expression increased. Results establish that lactocrine signaling effects morphogenetic changes in developing uterine tissues that may determine reproductive capacity later in life. PMID:23136302

  10. Cystic adenomyosis spreading into subserosal-peduncolated myoma: How to explain it?

    2015-01-01

    Conclusions: In this case, the peculiar growth pattern of cystic adenomyosis in a myoma represents a singular condition rarely reported in the medical literature. We therefore support the pathogenetic theory that the disease might have been caused by direct proliferation of endometrial cells within a peduncolated- subserosal myoma.

    Uterine secretions have a dominant impact on the environment in which embryo development takes place. The uterine serpins (SERPINA14, previously known as UTMP) are found most abundantly during pregnancy in the uterus of ruminants. Although progesterone is currently assumed to be the major regulator of SERPINA14 expression, our recent study of transcriptome changes in bovine endometrium during the estrous cycle unexpectedly detected a marked upregulation of SERPINA14 mRNA levels at estrus. The present study describes the full-length mRNA sequence, genomic organization, and putative promoter elements of the SERPINA14 gene. The SERPINA14 mRNA abundance was quantified by real-time RT-PCR in intercaruncular endometrium at several time points during the estrous cycle and early pregnancy. Highest levels were found at estrus, followed by a dramatic decrease and a moderate expression during the luteal phase. Transcript levels were higher in pregnant endometrium compared with controls at Day 18. At estrus, immunoreactive protein was localized in deep glandular epithelium, and Western blotting concomitantly showed the 52-kDa form in uterine flushings. SERPINA14 mRNA was significantly upregulated in glandular endometrial cells in vitro after stimulation with estradiol-17beta and progesterone, but not after interferon-tau treatment. Our results clearly demonstrate that SERPINA14 appears distinctly in bovine endometrium during the estrus phase. A supporting role toward providing a well-prepared endometrial environment for passing gametes, especially sperm, is assumed. PMID:19494250

    Full Text Available Laparoscopic minilaparotomy in 6 patients using the Maher abdominal elevator facilitated both quicker enucleation and morcellation of the myoma and suture of the myoma cavity. Myoma reduction in 12 patients by electrosurgery resulted in a 60% reduction in myoma diameter with failure in 2 patients. This technique may avoid myomectomy and be particularly useful in patients with infertility or near menopause.

  16. Differences in progesterone concentrations and mRNA expressions of progesterone receptors in bovine endometrial tissue between the uterine horns ipsilateral and contralateral to the corpus luteum.

    Takahashi, Hiroto; Haneda, Shingo; Kayano, Mitsunori; Matsui, Motozumi

    2016-05-01

    Because the establishment of pregnancy begins at the uterine horn ipsilateral to the corpus luteum (ipsi-horn) in cattle, levels of progesterone (P4) and receptor expression in the endometrial tissue, which regulate the intrauterine environment for embryo development, may differ between the ipsi-horn and the uterine horn contralateral to corpus luteum (contra-horn). The aim of the present study was to determine the endometrial tissue P4 concentrations and nuclear progesterone receptor (PGR), progesterone receptor membrane component 1 (PGRMC1) and PGRMC2 mRNA expressions in the cranial and middle parts of the uterine horns during the luteal phase. The results showed higher endometrial tissue P4 concentrations in the cranial part of the ipsi-horn than in that of the contra-horn (Pmiddle part, there were no changes in the endometrial tissue P4 concentrations and P4 receptor expressions during the luteal phase. In conclusion, the differences in dynamics of endometrial tissue P4 concentrations and P4 receptor expressions between the uterine horns ipsilateral and contralateral to the ovary containing a corpus luteum may cause differences in the intrauterine environment for both the ipsi- and contra-horns.

  19. Microscopic endometrial perivascular epithelioid cell nodules: a case report with the earliest presentation of a uterine perivascular epithelioid cell tumor

    Fang Chia-Lang

    2012-09-01

    Full Text Available Abstract Perivascular epithelioid cell (PEC tumors (PEComas are a family of related mesenchymal tumors composed of PECs which co-express melanocytic and smooth muscle markers. Although their distinctive histologic, immunohistochemical, ultrastructural, and genetic features have been clearly demonstrated, their histogenesis and normal counterpart remain largely unknown. Precursor lesions of PEComas have rarely been reported. We herein describe a tuberous sclerosis patient with microscopic PEC nodules in the endometrium of adenomyosis, pelvic endometriosis, an ovarian endometriotic cyst, and the endometrium of the uterine cavity. The nodules showed a mixture of spindle-shaped and epithelioid cells concentrically arranged around small arteries. The cells exhibited uniform nuclei, light eosinophilic cytoplasm, and immunoreactivity with HMB-45 and CD10. Some nodules revealed continuity with a PEComa in the myometrium. These findings support microscopic endometrial PEC nodules possibly being precursor lesions of uterine PEComas. The wide distribution of the nodules in the pelvis may be related to the multicentricity of PEComas in tuberous sclerosis patients. Owing to the immunoreactivity with CD10, microscopic endometrial PEC nodules may be misinterpreted as endothelial stromal cells unless melanocytic markers are stained. To the best of our knowledge, this is a case with the earliest manifestation of PEC lesions occurring in the endometrium.

  20. Laser-induced interstitial thermotherapy (LITT) for treatment of uterine leiomyomas: 750 myomas were treated by LITT and the results over a five-year period are analyzed

    Chapman, Roxana

    1997-05-01

    Approximately 750 leiomyomas of 250 symptomatic patients were treated by LITT over a five-year period. Only 12% were lost to follow-up. Most were treated by a combination of the KTP/YAG laser, rarely by one or the other alone, and a few with the diode laser. The fiber optic was inserted 2 cm apart and, depending on the size of the tumor, 480 - 20,000 Joules were required. Most were treated laparoscopically but very large myomas were treated percutaneously under ultrasound control. Symptoms were nearly always relieved and the six failures were found to be due to unrecognized adenomyosis and other associated pathology. Half the patients complaining of infertility became pregnant and, in those whose only pathology had been leiomyomas it approached 90%. Vaginal delivery was not found to be contraindicated. Finally, oestrogen receptors and epidermal growth factor were found to be destroyed. It is concluded that LITT enables leiomyomas of all sizes and locations to be treated by a minimally invasive method with preservation of the uterus.

    Metritis and endometritis commonly occur in dairy cows after calving. Although numerous studies have been performed to identify the causative pathogens, a complete overview has not been done. Metagenomic studies have analyzed the bacterial populations of uterine flush samples from postpartum (pp) dairy cows, but the microbiota in the uterine luminal fluid may differ from the microbiota of the endometrium itself, and important putative pathogens may have been overlooked. In the present study, we compared the microbiota of the uterine lumen and the endometrium of healthy, metritic, and endometritic cows. Samples were collected from 68 Holstein dairy cows at 1, 4, and 7 weeks pp, and the data were analyzed by deep sequencing of the V1 and V2 hypervariable regions of the 16S ribosomal RNA gene. The results showed that Porphyromonadaceae, Fusobacteriaceae, Leptotrichiaceae, and Mycoplasmataceae may be associated with uterine disease. The microbiota of the uterine flush samples and the endometrial biopsies were correlated, but the microbiota of the biopsies was more diverse. Fusobacteriaceae and Leptotrichiaceae were not observed in the biopsies at week 7, whereas they accounted for 20% and 13%, respectively, of the bacterial populations in the flush samples. The Mycoplasmataceae family was observed in much higher quantity in the flush samples than in the biopsies of the endometritis groups at weeks 4 and 7. Our findings support the observations of previous metagenomic studies and illustrate the importance of including endometrial biopsies to obtain more detailed knowledge of the pp uterine microbiota.

    2015-06-01

    Full Text Available Background: Submucous myomas may be associated with menorrhagia, infertility and dysmenorrhea. Objective: The aim of this study was to determine the long term effects of submucousal myoma resection on menorrhagia and infertility; also to detect whether the type, size, and location of myoma affect the surgical success. Materials and Methods: .Totally 98 women referred to hysteroscopy for symptomatic submucousal fibroids (menorrhagia (n=51 and infertility (n=47 between 2005- 2010 were enrolled in this historical cohort study Pregnancy rates and menstrual improvement rates were compared according to myoma characteristics (size, type and location. Results: After a mean postoperative period of 23±10 months in 51 patients with excessive bleeding, 13 had recurrent menorrhagia (25%. In Other 38 patients excessive bleeding was improved (75%. The improvement rates by location and myoma type: lower segment 100%, fundus 92%, and corpus 63%; type 0 70%, type 1 78%, type 2 80%. The mean sizes of myoma in recurred and improved patients were 23.33 mm and 29.88 mm respectively. 28 of 47 infertile women spontaneously experienced thirty pregnancies (60%. Pregnancy rates according to myoma location and type: lower segment 50%, fundus 57%, and corpus 80%; type 0 75%, type 1 62%, type 2 50%. The mean myoma size in patients who became pregnant was 30.38 mm; in patients who did not conceive was 29.95 mm. Conclusion: The myoma characetesitics do not affect improvement rates after hysteroscopic myomectomy in patients with unexplained infertility or excessive uterine bleeding.

Conclusion: Endometrial pathologies are associated significantly with endometrial spiral artery Doppler changes.Key words: Spiral artery, Doppler ultrasonography, endometrium

  4. Body diffusion-weighted MR imaging of uterine endometrial cancer: Is it helpful in the detection of cancer in nonenhanced MR imaging?

    Objective: In this study, the authors discussed the feasibility and value of diffusion-weighted (DW) MR imaging in the detection of uterine endometrial cancer in addition to conventional nonenhanced MR images. Methods and materials: DW images of endometrial cancer in 23 patients were examined by using a 1.5-T MR scanner. This study investigated whether or not DW images offer additional incremental value to conventional nonenhanced MR imaging in comparison with histopathological results. Moreover, the apparent diffusion coefficient (ADC) values were measured in the regions of interest within the endometrial cancer and compared with those of normal endometrium and myometrium in 31 volunteers, leiomyoma in 14 patients and adenomyosis in 10 patients. The Wilcoxon rank sum test was used, with a p -3 mm2/s, which was significantly lower than those of the normal endometrium, myometrium, leiomyoma and adenomyosis (p < 0.05). Conclusion: DW imaging can be helpful in the detection of uterine endometrial cancer in nonenhanced MR imaging.

The Wilcoxon rank sum test was used, with a p < 0.05 considered statistically significant. Results: In 19 of 23 patients, endometrial cancers were detected only on T2-weighted images. In the remaining 4 patients, of whom two had coexisting leiomyoma, no cancer was detected on T2-weighted images. This corresponds to an 83% detection sensitivity for the carcinomas. When DW images and fused DW images/T2-weighted images were used in addition to the T2-weighted images, cancers were identified in 3 of the remaining 4 patients in addition to the 19 patients (overall detection sensitivity of 96%). The mean ADC value of endometrial cancer (n = 22) was (0.97 {+-} 0.19) x 10{sup -3} mm{sup 2}/s, which was significantly lower than those of the normal endometrium, myometrium, leiomyoma and adenomyosis (p < 0.05). Conclusion: DW imaging can be helpful in the detection of uterine endometrial cancer in nonenhanced MR imaging.

  9. Relationship between uterine expression of matrix metalloproteinases and their inhibitors and endometrial receptivity

    高飞; 魏鹏; 陈鑫磊; 张志宏; 刘以训

    2002-01-01

    In order to investigate the relationship between the endometrial receptivity and matrix metalloproteinase-2 (MMP-2) and tissue inhibitor of metalloproteinase-1,-3 (TIMP-1,-3) in the endometrium, we used early pregnant mice as the animal model and studied the expression of MMP-2, TIMP-1,-3 in the endometrium in relation to the number of implantation sites after RU486 treatment. The results indicated that RU486 could significantly inhibit embryo implantation and change the expression of MMP-2 and TIMP-1,-3 in a dose-dependent pattern. When the mice were treated with 12 mg/kg RU486, there were a few embryos implanted as compared with the control. The expression of matrix metalloproteinase MMP-2 was low during the period of "implantation window", while the tissue inhibitor of metalloproteinase in the endometrial cells was high, suggesting that the activity of the proteolytic enzyme was strictly controlled by its inhibitors. After RU486 treatment, the generation of TIMP-1,3 was decreased while the MMP-2 was significantly increased, indicating that the normal balance between the activators and their inhibitors in the tissue was broken and the extracellular matrix was excessively degraded, subsequently the embryo implantation was inhibited. Therefore, it is suggested that the anti-implantation effect of RU486 may be mediated by MMPs and their inhibitors TIMPs.

    2011-05-01

    Full Text Available Objective. To evaluate accuracy of transvaginal sonography (TVS and hysteroscopy in detection of intrauterine pathology in infertile women. Subjects and methods. This retrospective study was conducted in 56 infertile women with abnormal transvaginal ultrasound findings of the uterine cavity which was performed during the midfollicular phase as a part of routine infertility workup. Hysteroscopy was performed between 6th and 10th day of cycle. Results. The mean age of the subjects was 31.9±4.0. The most frequent ultrasound finding was endometrial polyp in 34 (60.7% patients, septate uterus in 8 (14.3% patients, submucosal myoma in 7 (12.5% patients, endometrial hyperplasia in 5 (8.9% patients and Syndroma Ascherman in 2 (3.6% patients. Hysteroscopy confirmed 20 (35.7% polyps, the same number of myomas, septate uterus and Syndroma Ascherman as detected by ultrasound, (7 (12.5%, 8 (14.3% and 2 (3.6%, respectively and 19 (33.9% endometrial hyperplasia. In 46 women with histological excamination, the sensitivity of TVS and hysteroscopy in the diagnosis of endometrial polyps were identical - 100%, while the specificity was higher in hysteroscopy than in TVS (92.3% versus 56.4%, p<0.001. The sensitivity of TVS in the diagnosis of endometrial hyperplasia was higher than that of hysteroscopy (86.4% versus 22.7%, p<0.001, while specificity was identical, of 100%. Accordance between hysteroscopy and histology was good (k=0.79, between ultrasound and histology was moderete (k=0.59. Conclusion. Hysteroscopy appeared to be more reliable in diagnosis than TVS. The use of a high frequency ultrasound probe leads us to a lack of diagnostic clarity between endometrial polyps and hyperplasia.

In eight surgically proven cases of solid ovarian tumor and in ten uterine subserosal myoma patients, contrast-enhanced CT images were obtained. Two genitourinary radiologists reviewed the findings with regard to degree of enhancement of the mass as compared with enhancement of uterine myometrium, thickening of round ligaments, visualization of normal ovaries, contour of the mass, and the presence of ascites in the pelvic cavity. Six of eight ovarian tumors but only two of ten uterine myomas were less enhanced than normal uterine myometrium (p0.05). The contour of the mass was lobulated in two of eight ovarian tumor patients, but in five of ten uterine myoma patients (p>0.05). CT findings suggestive of solid ovarian tumor were less contrast enhancement of the mass than of normal uterine myometrium, pelvic ascites, and nonvisualization of normal ovary

    To correlate transvaginal sonographic findings with histopathology in diffuse uterine adenomyosis. We prospectively analyzed the transvaginal sonographic findings of 15 patients undergoing hysterectomy for adenomyosis. Diffuse adenomyosis was diagnosed when an abnormal echotexture (heterogenous echogenicity, decreased echogenicity, increased echogenicity, cystic lesion) was present in myometrium of enlarged uterus. We evaluate the size of the uterus, abnormal echotexture in myometrium and anterior and posterior myometrial wall thickness'. Transvaginal sonographic findings of diffuse adenomyosis are enlarged uterus (n=15), heterogenous and increased echogenicity in myometrium (n=10), heterogenous echogenicity in myometrium (n=4), heterogenous and increased echogenicity with cystic lesion lesion in myometrium (n=1). The posterior myometrial wall is equal to anterior wall (n=7), thicker than anterior wall (n=4), thinner than anterior wall (n=4). The histopathologic findings including ectopic endometrial gland (n=14), muscular hypertrophy (n=15), myoma (n=4). Diffuse adenomyosis was confirmed except one case that proved myoma. Transvaginal sonographic findings of enlarged uterus with heterogenous and increased echotexture in myometrium of adenomyosis is correlated with ectopic endometrial gland with secondary muscular hypertrophy.

    Productivity rates directly depend on the fertility of a herd, which in turn can be influenced by many factors. Semen deposited in the female reproductive tract is foreign to the body and, in response to this invasion, produces an inflammatory reaction, which is characterized by rapid infusion of polymorphonuclear (PMN) cells. Techniques to obtain an endometrial sample are usually invasive and can mask the true inflammatory response. Ultrasound is a noninvasive technique and can contribute to the diagnosis of postartificial insemination (AI) inflammatory response in cattle. The present study was divided into two experiments. The aim of experiment 1 was to compare two methods of endometrial cytology collection, uterine cytobrush (UC) and uterine lavage (UL), and their effects on uterine hemodynamics that provide information about blood flow. The two methods were evaluated by Doppler ultrasound using the spectral and color modes. For that purpose, 19 Nellore cows were synchronized for timed AI and subjected to UC (n = 9) or UL (n = 10). The techniques were performed 4 hours after AI. The results showed that both techniques allow collection of a good quality sample and with enough PMN cells to perform counting. More PMN cells were obtained by UL than UC. There was no difference in uterine blood flow between the UC and UL groups in any of the periods evaluated (34 hours before and 4, 24, and 48 hours after collection of uterine sample). On the basis of results of experiment 1, the effect of UL on fertility was studied in experiment 2. A total of 128 Nellore cows were synchronized for TAI; 35 cows were subjected to endometrial cytology by UL 4 hours after AI, and 93 were not submitted to any procedure (control). Pregnancy diagnosis was performed by transrectal ultrasound 30 days after AI. Pregnancy rates did not differ between UL (54.29%) and control (56.99%) groups. The results of this study showed that UL allows the collection of more representative cells of

    Full Text Available   "nAbnormal uterine bleeding, whether in peri menopausal or postmenopausal patients, is an important clinical concern and results in much medical intervention. When bleeding occurs in women over 40 years of age as well as any postmenopausal women, endometrial assessment is mandatory. In the past and present, many clinicians prefer to begin such assessment with blind endometrial sampling. However, when an ultrasound-based approach to such patients is present, a thin distinct endometrial echo excludes significant pathology, assuming it is performed at an appropriate time if the patient is, in fact, cycling. When a thin distinct endometrial echo is not visualized (inadequate visualization or presence of thickened echo then saline infusion sonohysterography can help to triage patients to no anatomic pathology, globally thickened anatomic pathology that may then be evaluated with blind endometrial sampling, and focal abnormalities that must be evaluated under direct vision. Such an ultrasound-based approach will not only help to exclude endometrial carcinoma, but also to identify the source of any bleeding for better clinical management. MRI has no role as a screening technique for endometrial carcinoma however the accuracy of MRI in differentiating non invasive from invasive carcinoma is high.   

  19. Optimal uterine anatomy and physiology necessary for normal implantation and placentation.

    2016-04-01

    The authors review aberrations of uterine anatomy and physiology affecting pregnancy outcomes with IVF. In the case of endometriosis and hydrosalpinx, pathologies outside of the uterus alter the uterine endometrium. In the case of endometriosis, Dominique de Ziegler outlines the numerous changes in gene expression and the central role of inflammation in causing progesterone resistance. With endometriosis, the absence of ovarian function inherent in deferred transfer, with or without a more lengthy suppression of ovarian function, appears to be sufficient to restore normal function of eutopic endometrium. Because laparoscopy is no longer routine in the evaluation of infertility, unrecognized endometriosis then becomes irrelevant in the context of assisted reproductive technology. With hydrosalpinx and submucus myomas, the implantation factor HOXA-10 is suppressed in the endometrium and, with myomas, even in areas of the uterus not directly affected. Daniela Galliano reviews various uterine pathologies, the most enigmatic being adenomyosis, where the endometrium also manifests many of the changes seen in endometriosis and deferred transfer with extended suppression appears to provide the best outcomes. Ettore Cicinelli's group has extensively studied the diagnosis and treatment of endometritis, and although more definitive diagnosis and care of this covert disorder may await techniques such as sequencing of the endometrial microbiome, it undoubtedly is an important factor in implantation failure, deserving our attention and treatment.

  20. Progestins Upregulate FKBP51 Expression in Human Endometrial Stromal Cells to Induce Functional Progesterone and Glucocorticoid Withdrawal: Implications for Contraceptive- Associated Abnormal Uterine Bleeding.

    Ozlem Guzeloglu Kayisli

    Full Text Available Use of long-acting progestin only contraceptives (LAPCs offers a discrete and highly effective family planning method. Abnormal uterine bleeding (AUB is the major side effect of, and cause for, discontinuation of LAPCs. The endometria of LAPC-treated women display abnormally enlarged, fragile blood vessels, decreased endometrial blood flow and oxidative stress. To understanding to mechanisms underlying AUB, we propose to identify LAPC-modulated unique gene cluster(s in human endometrial stromal cells (HESCs. Protein and RNA isolated from cultured HESCs treated 7 days with estradiol (E2 or E2+ medroxyprogesterone acetate (MPA or E2+ etonogestrel (ETO or E2+ progesterone (P4 were analyzed by quantitative Real-time (q-PCR and immunoblotting. HSCORES were determined for immunostained-paired endometria of pre-and 3 months post-Depot MPA (DMPA treated women and ovariectomized guinea pigs (GPs treated with placebo or E2 or MPA or E2+MPA for 21 days. In HESCs, whole genome analysis identified a 67 gene group regulated by all three progestins, whereas a 235 gene group was regulated by E2+ETO and E2+MPA, but not E2+P4. Ingenuity pathway analysis identified glucocorticoid receptor (GR activation as one of upstream regulators of the 235 MPA and ETO-specific genes. Among these, microarray results demonstrated significant enhancement of FKBP51, a repressor of PR/GR transcriptional activity, by both MPA and ETO. q-PCR and immunoblot analysis confirmed the microarray results. In endometria of post-DMPA versus pre-DMPA administered women, FKBP51 expression was significantly increased in endometrial stromal and glandular cells. In GPs, E2+MPA or MPA significantly increased FKBP51 immunoreactivity in endometrial stromal and glandular cells versus placebo- and E2-administered groups. MPA or ETO administration activates GR signaling and increases endometrial FKBP51 expression, which could be one of the mechanisms causing AUB by inhibiting PR and GR

  3. Role of transvaginal sonography and hysteroscopy in abnormal uterine bleeding: does the diagnostic yield increase by combining transvaginal sonography, hysteroscopy and biopsy?

    Nivedita Krishnamoorthy

    2014-08-01

    Methods: This was a descriptive cross sectional study between January 2013 to June2014 in Sri Manakula Vinayagar medical college and hospital. After obtaining ethics committee approval, 100 consecutive patients with abnormal uterine bleeding between the age group of 35 and 55 years, who consented to participate in the study, were subjected to transvaginal sonography followed by diagnostic hysteroscopy combined with a directed biopsy. TVS and hysteroscopy was performed by two different investigators. The endometrial curettings and any intracavitary lesion were subjected to histopathological examination. Results tabulated and analysed using MS EXCEL and cross tabulation using Epi-info. Sensitivity, specificity, PPV, NPV for each pathology by TVS and hysteroscopy with HPE as the gold standard was calculated. Also the pathology causing abnormal uterine bleeding was computed by taking into account the endometrial characteristics and the associated lesions diagnosed by TVS, hysteroscopy and histopathological examination report. Results: 61 patients had only single lesions in the form of normal endometrium, atrophic endometrium, endometrial hyperplasia, endometrial polyp, malignancy and IU synechiae whereas 39 patients had lesions like intramural fibroids, adenomyosis, submucus myoma and polyps associated with different types of endometrium. The diagnostic accuracy of TVS and hysteroscopy were comparable for normal endometrium whereas hysteroscopy was found to be more accurate for endometrial polyps, endometrial hyperplasia and atrophic endometrium. Conclusions: The combination of transvaginal sonography, hysteroscopy and directed biopsy was found to increase the diagnostic yield in patients with abnormal uterine bleeding. As the diagnostic accuracy increased by combining the three modalities, an effective and appropriate management can be planned. [Int J Reprod Contracept Obstet Gynecol 2014; 3(4.000: 919-923

    Full Text Available Approximately 24 million European and more than 20 million North American women between the ages of 35 and 55 are suffering from uterine fibroids, i.e. 40% of all women in this age group are affected. The symptoms are excessive uterine bleeding, anaemia, pain and infertility. Many women find their quality of life severely compromised, and this leads to hysterectomy in many cases. So far there has been no effective and well-tolerated drug. The only approved drugs for the treatment of symptomatic uterine fibroids are GnRH agonists, but their use is relatively limited because of severe side effects due to the resulting low levels of estrogen causing hot flushes, depression, mood swings, loss of libido, vaginitis and loss of bone mineral density. As fibroid growth is dependent on progesterone, progesterone receptor modulators have proven effective in pilot studies. Two randomised double-blind studies have shown the effectiveness of the progesterone receptor modulator ulipristal acetate in the preoperative treatment of leiomyomas and the control of concomitant menorrhagia. No significant side effects have occurred under a dosage of 5 and 10 mg UPA over 3 months. A cessation of menorrhagia was observed after only 7 days, and a volume reduction of the uterine fibroids by 40% was achieved within 3 months and seemed to persist even 6 months after discontinuing the drug. A preparation with a dosage of 5 mg ulipristal acetate is available as Esmya® from the spring of 2012 for the preoperative treatment of leiomyomas.

  5. Dysfunctional uterine bleeding (DUB).

    1994-09-30

    Cyclic or irregular uterine bleeding is common in perimenarchal and perimenopausal women with or without endometrial hyperplasia. The disturbance often requires surgical treatment because of its negative effects on both blood loss and abnormal endometrial growth including the development of endometrial cancer. The endometrium is often overstimulated during the perimenopausal period when estrogen/progesterone production is unbalanced. A therapeutical approach with gonadotropin-releasing hormone agonist (GnRHa) was proposed in a depot formulation (Zoladex) that induces a sustained and reversible ovarian suppression. To avoid the risk of osteoporosis and to obtain adequate endometrial proliferation and differentiation during ovarian suppression, transdermal 17-beta-estradiol and oral progestin were administered. Results of 20 cases versus 20 controls showed a reduction of metrorrhagia, a normalization of hemoglobin plasma concentration, and an adequate proliferation and secretory differentiation of the endometrium of patients with abnormal endometrial growth. Abnormal uterine bleeding is mainly due to uterine fibrosis and an inadequate estrogen and/or progesterone production or to a disordered estrogen transport from blood into the endometrium. In premenopausal women, endometrial hyperplasia may be part of a continuum that is ultimately manifested in the histological and biological pattern of endometrial carcinoma. The regression of endometrial hyperplasia obtained by using the therapeutic regimen mentioned above represents a preventive measure for endometrial cancer. Finally the normalization of blood loss offers a good medical alternative to surgery for patients with DUB. PMID:7978956

    Cathepsins (CTSB and CTSL1) and their inhibitor, cystatin C (CST3), remodel uterine endometrium and placenta for transport of gases, micronutrients, and macromolecules essential for development and growth of the conceptus (embryo/fetus and placental membranes). We examined the temporal/spatial control of expression for CTSB, CTSL1, and CST3 mRNAs in endometria and placentae of pigs using three developmental models: 1) pigs were hysterectomized during the estrous cycle or pregnancy; 2) cyclic pigs were injected with estrogen to induce pseudopregnancy and were hysterectomized; and 3) pigs were ovariectomized, injected with progesterone, and hysterectomized. The abundance of CTSB, CTSL1, and CST3 mRNAs increased in endometrial epithelia during pregnancy and in response to exogenous progesterone but not estrogen. CST3 was also expressed in cells scattered within the stratum compactum stroma. Progesterone decreased epithelial but increased stromal compartment expression of CST3. CTSB increased in all chorionic epithelia, but CTSL1 was limited to chorionic epithelia that form areolae to absorb secretions from uterine glands. Based on the placental and endometrial distribution of CTSL1, we examined expression in the neonatal enterocytes known to transport immunoglobulins from colostrum. CTSL1 was also expressed in enterocytes of intestine from neonatal piglets. Therefore, CTSL1 is expressed by endometrial epithelia, placental areolae, and neonatal intestine, and it may function in the transport of macromolecules across these epithelia. Our results support the idea that reciprocal interactions between CSTL1, CTSB, and CST3 may be required to remodel endometrial and placental tissues for close apposition between maternal and fetal vasculatures and to facilitate transplacental transport of gases, micronutrients (amino acids, glucose), and macromolecules (proteins). Cysteine proteases and their inhibitors may also specifically modify proteins for successful utilization and

  10. Cost-Effectiveness of Global Endometrial Ablation vs. Hysterectomy for Treatment of Abnormal Uterine Bleeding: US Commercial and Medicaid Payer Perspectives

    Lenhart, Gregory M.; Bonafede, Machaon M.; Lukes, Andrea S.; Laughlin-Tommaso, Shannon K.

    2015-01-01

    Abstract Cost-effectiveness modeling studies of global endometrial ablation (GEA) for treatment of abnormal uterine bleeding (AUB) from a US perspective are lacking. The objective of this study was to model the cost-effectiveness of GEA vs. hysterectomy for treatment of AUB in the United States from both commercial and Medicaid payer perspectives. The study team developed a 1-, 3-, and 5-year semi-Markov decision-analytic model to simulate 2 hypothetical patient cohorts of women with AUB—1 treated with GEA and the other with hysterectomy. Clinical and economic data (including treatment patterns, health care resource utilization, direct costs, and productivity costs) came from analyses of commercial and Medicaid claims databases. Analysis results show that cost savings with simultaneous reduction in treatment complications and fewer days lost from work are achieved with GEA versus hysterectomy over almost all time horizons and under both the commercial payer and Medicaid perspectives. Cost-effectiveness metrics also favor GEA over hysterectomy from both the commercial payer and Medicaid payer perspectives—evidence strongly supporting the clinical-economic value about GEA versus hysterectomy. Results will interest clinicians, health care payers, and self-insured employers striving for cost-effective AUB treatments. (Population Health Management 2015;18:373–382) PMID:25714906

    2015-02-01

    Full Text Available Torsion of ovary especially dermoid is very common but torsion of uterus is a rare phenomenon. Torsion of gravid uterus has been reported in many journals but torsion of non - gravid uterus is rarest of the rare. Causes usually associated are big myomas inv olving uterine body and sparing cervix , and sometimes uterine anomalies and adnexal masses. Preoperative diagnosis is very difficult and usually diagnosis is made during laparotomy. Here we are going to discuss a case of non - gravid uterine torsion in a 47 year old lady due to big intramural fibroid involving uterine body but sparing the cervix. Cervix became thin , elongated and acted like a pedicle/pivot around which torsion took place. The patient was admitted with acute abdominal pain and shock.

  14. Enzymes of the AKR1B and AKR1C subfamilies and uterine diseases

    Tea eLanisnik Rizner

    2012-03-01

    Full Text Available Endometrial and cervical cancers, uterine myoma, and endometriosis are very common uterine diseases. Worldwide, more than 800,000 women are affected annually by gynecological cancers, as a result of which, more than 360,000 die. During their reproductive age, about 70% of women develop uterine myomas, 10% to 15% suffer from endometriosis, and 35% to 50% from infertility associated with endometriosis. Uterine diseases are associated with aberrant inflammatory responses and concomitant increased production of prostaglandins (PG. They are also related to decreased differentiation, due to low levels of protective progesterone and retinoic acid, and to enhanced proliferation, due to high local concentrations of estrogens. The pathogenesis of these diseases can thus be attributed to disturbed PG, estrogen and retinoid metabolism and actions. Five human members of the aldo-keto reductase 1B (AKR1B and 1C (AKR1C superfamilies, i.e., AKR1B1, AKR1B10, AKR1C1, AKR1C2 and AKR1C3, have roles in these processes and can thus be implicated in uterine diseases. AKR1B1 and AKR1C3 catalyze the formation of PGF2alpha which stimulates cell proliferation. AKR1C3 converts PGD2 to 9alpha,11beta-PGF2, and thus counteracts the formation of 15deoxy-PGJ2, which can activate pro-apoptotic peroxisome-proliferator-activated receptor beta. AKR1B10 catalyzes the reduction of retinal to retinol, and in thus lessens the formation of retinoic acid, with potential pro-differentiating actions. The AKR1C1-AKR1C3 enzymes also act as 17-keto- and 20-ketosteroid reductases to varying extents, and are implicated in increased estradiol and decreased progesterone levels. This review comprises a short introduction to uterine diseases, followed by an overview of the current literature on the AKR1B and AKR1C expression in the uterus and in uterine diseases. The potential implications of the AKR1B and AKR1C enzymes and their pathophysiologies are then discussed, followed by conclusions and

  15. Early ultrasonographic findings after a uterine fibroid embolization: the value of differentiate from procedure-related uterine infection

    To evaluate the early ultrasonographic (US) findings from the uterus and myoma after a uterine fibroid embolization (UFE). From March 2004 to January 2006, eleven patients (27-48 years, mean:37 years) with UFE to treat symptomatic uterine myoma, were retrospectively reviewed. A serial follow up gray-scale and color Doppler US were performed from one day to two weeks following a UFE. The US findings were evaluated for the presence and distribution pattern of air, time of air loss, and presence of fluid collection in the uterine cavity and color Doppler (SD Comment: Doppler is name. Should perhaps be upper case) signal. Numerous high echoes with reverberation artifacts (which suggest air), were observed within the myoma (in all cases), one day after UFE. A branching linear echo pattern was observed in 4 cases (36%), whereas scattered echoes were observed in 7 cases (64%). Progressive loss of air, within 7 days of a UFE, was observed in 9 cases (82%), whereas 2 cases (12%) were observed within 14 days of a UFE. Abnormal fluid collection in the uterine cavity and a color Doppler signal within the myoma was not observed for all cases. Branching or scattered echoes (suggesting air), are normally found within the myoma after a UFE, but these echoes disappeared within 2 weeks. These early US findings can be useful in differentiating from myoma infections after a UFE

    The puerperal uterine inversion is a rare and severe complication occurring in the third stage of labour. The mechanisms are not completely known. However, extrinsic factors such as oxytocic arrests after a prolonged labour, umbilical cord traction or abdominal expression are pointed. Other intrinsic factors such as primiparity, uterine hypotonia, various placental localizations, fundic myoma or short umbilical cord were also reported. The diagnosis of the uterine inversion is mainly supported by clinical symptoms. It is based on three elements: haemorrhage, shock and a strong pelvic pain. The immediate treatment of the uterine inversion is required. It is based on a medical reanimation associated with firstly a manual reduction then surgical treatment using various techniques. We report an observation of a 25 years old grand multiparous patient with a subacute uterine inversion after delivery at home. PMID:21516244

    Jeong, Kyungah; Lee, Sa Ra; Park, Sanghui

    2016-03-01

    A 50-year-old peri-menopausal woman presented with hard palpable mass on her lower abdomen and anemia from heavy menstrual bleeding. Ultrasonography showed a 13×12 cm sized hypoechoic solid mass in pelvis and a 2.5×2 cm hypoechoic cystic mass in uterine endometrium. Abdomino-pelvic computed tomography revealed a hypodense pelvic mass without enhancement, suggesting a leiomyoma of intraligamentary type or sex cord tumor of right ovary with submucosal myoma of uterus. Laparoscopy revealed a large Sertoli-Leydig cell tumor of right ovary with a very rare entity of intra-endometrial uterine leiomyoma accompanied by adenomyosis. The final diagnosis of ovarian sex-cord tumor (Sertoli-Leydig cell), stage Ia with intra-endometrial leiomyoma with adenomyosis, was made. Considering the large size of the tumor and poorly differentiated nature, 6 cycles of chemotherapy with Taxol and Carboplatin regimen were administered. There is neither evidence of major complications nor recurrence during 20 months' follow-up. PMID:26847310

    Uterine papillary serous carcinoma (UPSC) is a histologic variant of endometrial cancer that accounts for only 10% of new cases of uterine cancer but is responsible for 40% of deaths from the disease. UPSC is an aggressive tumor with a predilection for early spread beyond the uterus. Treatment for UPSC typically entails surgery and in most women is followed by multimodality adjuvant therapy. In this review, we describe the epidemiology, natural history, treatment, and outcome of UPSC. PMID:21508697

  2. Uterine Fibroid Embolization Can Still Be Improved: Observations on Post-Procedure Magnetic Resonance Imaging

    PURPOSE: To evaluate the efficacy and completeness of uterine fibroid embolization (UFE) measured by changes in volume and signal intensity at magnetic resonance imaging (MRI), and to compare with clinical outcome. MATERIAL AND METHODS: 40 women with symptomatic uterine fibroids underwent bilateral uterine artery embolization. At MRI studies, including post-contrast sequences before and repeatedly after treatment, the uterus and dominant fibroids were evaluated for volume, location, and contrast enhancement. Prior to treatment, all myomas showed significant contrast enhancement. The mean uterine volume was 929 ml. Clinical examinations with emphasis on menorrhagia, pelvic pain, and urinary dysfunction were performed before and 6 and 12 months after treatment. RESULTS: UFE was bilaterally successful in 38 patients. After UFE, MRI showed no enhancement of myomas in 30 patients. In 8 patients, post-procedural MRI revealed partially remaining vascularization of fibroids despite angiographically complete embolization of the uterine arteries. On average, uterine volume decreased by 46.2% at 12 months. There was significant improvement of symptoms in the majority of patients, but slightly less improvement in patients with partially remaining vascularization of myomas. CONCLUSION: UFE causes significant volume reduction of myomas and clinical improvement. MRI can reveal remaining vascularization in myomas despite angiographically complete embolization of uterine arteries

    the menacme or postmenopause period. All patients underwent a sonohysterography, and later a hysteroscopy and/or a hysterectomy. The sonohysterographies were evaluated by two different physicians, and the diagnoses were compared. Results: the sonohysterography method showed high sensitivity and specificity for the diagnosis of benign pathologies in the uterine cavity. First, in the presence of polyps the sensitivity and specificity rates were 100 and 97%, respectively, second, in the presence of submucous myoma, they were 83 and 100%, and finally, concerning endometrial hyperplasia and normal endometrium, they were 100%. We diagnosed thirty-three cases of polyps, thirteen cases of submucous myoma, four cases of endometrial hyperplasia and three normal cases. The correlation between the diagnoses provided by the two physicians was high. Conclusions: sonohysterography is a safe and fast method which is very well tolerated by the patient, and has low levels of complications. Its high sensitivity and specificity allow this method to be used for routine diagnosis concerning benign pathologies in the uterine cavity of patients presenting abnormal uterine bleeding.

    2004-12-01

    endometrial abnormalities based upon transvaginal ultrasonography were studied. Hysterosonography, diagnostic hysteroscopy and oriented biopsy were performed and the Kia was used to compare results. RESULTS: The most frequent abnormalities were polyps (58%, synechiae (20%, submucous myoma (12% and endometrial thickening (6%. The uterine cavity was considered normal in 4% of the evaluations by hysteroscopy. The sensitivity of hysterosonography to diagnose polyps was of 89.7%, the specificity of 81.0% and the KIA of 71.1%. For synechia sensitivity of hysterosonography was of 80%, specificity of 100% and the KIA of 86.5%; for submucous myoma sensitivity was of 83.3%; specificity of 97.7% and the KIA of 81.1%, and for endometrial thickening, sensitivity was of 33.3%, specificity of 89.4% and the KIA of 15.5%. CONCLUSION: Hysterosonography showed very good agreement with hysteroscopy for the diagnosis of synechiae and submucous myomas; good agreement for polyps and poor agreement for endometrial thickening. Based upon this data hysterosonography may be deemed a simple, efficient, and accurate method for the evaluation of the uterine cavity in the postmenopausal period.

  9. Usefulness of Sonohysterography in the Differentiation of Endometrial and EndometriaI Cavity Abnormalities :Comparison with TransvaginaI Sonography

    The purpose of this study was to evaluate the diagnostic accuracy and usefulness odsonohysterography(SH) in the diagnosis of endometrial and endometrial cavity abnormalities. 51 patients with suspected endometrial abnormalities were examined with both transvaginal sonography(TVS) and SH. The results of both techniques were correlated with pathologic findings obtained by surgical procedures and the accuracies of the techniques were compared. Of 55 histologically proven lesions, there were endometrialhyperplasia(n=4), endometrial polyp(n=30), endometrial polyp with hyperplasia(n=2), placental polyp(n=3), submucosal myoma(n=10) and synechia(n=6). The diagnostic accuracy in differentiation of endometrial and endometrial cavity abnormalities was increased from 79% in conventional TVS to 95% in SH(p<0.001). SH was a simple and well-tolerated technique to perform, favorably depicting the endometrial and endometrial cavity abnormalities that were equivocal on TVS

The uterine inversion was likely due to a leiomyoma. Th...

  13. Preliminary Experience with Locoregional Intraarterial Chemotherapy of Uterine Cervical or Endometrial Cancer Using the Peripheral Implantable Port System (PIPSTM): A Feasibility Study

    The purpose of this study was to assess the suitability of a percutaneously implantable catheter port system (PIPS)for repeated intraarterial locoregional chemotherapy (ILC) for cervical and endometrial carcinoma. In 30 patients with advanced, recurrent, or high-risk cervical (n 23) or endometrial(n = 7) carcinoma, PIPS for ILC was implanted via a femoral access, the catheter localized in the infrarenal abdominal aorta. Chemotherapy was performed adjuvantly after surgery(n = 14) or neo-adjuvantly to enable surgery, or for palliation (n = 16). Port implantation, catheter placement, and repeated port puncture was uneventful in all patients.Complications included catheter dislocation (n = 1),catheter thrombosis (n = 2), subcutaneous infection(n = 1), port-bed skin atrophy (n = 1),requiring port explantation in 3 patients. At 2 years follow-up,complete remission was observed in 7/14 patients with adjuvant chemotherapy, partial remission in 3/14. Successful down-staging could be achieved in 4/8 patients with neo-adjuvant chemotherapy. The PIPS is suitable for repeated ILC which may be a valuable method for pre- and post-surgical therapy of advanced or high-risk cervical and endometrial cancer, for adjuvant chemotherapy as well as neo-adjuvantly for down-staging, or for palliation

Hysterectomy, the most common surgical treatment of AUB, has significant morbidity, low mortality, long recovery, and high associated health care costs. Global endometrial ablation (GEA provides a surgical alternative with reduced morbidity, cost, and recovery time. The NovaSure® system utilizes unique radiofrequency impedance-based GEA technology. This study evaluated cost effectiveness of AUB treatment with NovaSure ablation versus other GEA modalities and versus hysterectomy from the US commercial and Medicaid payer perspectives. Methods: A health state transition (semi-Markov model was developed using epidemiologic, clinical, and economic data from commercial and Medicaid claims database analyses, supplemented by published literature. Three hypothetical cohorts of women receiving AUB interventions were simulated over 1-, 3-, and 5-year horizons to evaluate clinical and economic outcomes for NovaSure, other GEA modalities, and hysterectomy. Results: Model analyses show lower costs for NovaSure-treated patients than for those treated with other GEA modalities or hysterectomy over all time frames under commercial payer and Medicaid perspectives. By Year 3, cost savings versus other GEA were $930 (commercial and $3,000 (Medicaid; cost savings versus hysterectomy were $6,500 (commercial and $8,900 (Medicaid. Coinciding with a 43%–71% reduction in need for re-ablation, there were 69%–88% fewer intervention/reintervention complications for NovaSure-treated patients versus other GEA modalities

  15. Evaluation of uterine adenomyosis by magnetic resonance imaging

    To assess the capability of magnetic resonance imaging (MR imaging) to enable the detection of the characteristic findings of uterine adenomyosis, 50 pathologically proved adenomyosis lesions (27 cases accompanied with uterine myoma) were chosen and their MRI findings were reviewed. MR imaging was performed with a superconducting magnet, Magnex 150/HP ( 1.5 Tesla), 100 ( 1.0 Tesla) and α (0.5 Tesla). When both T1-weighted images and T2-weighted images were analyzed, the detection rate of adenomyosis was 82%. In 9 cases (18%), adenomyosis was not detected, due to motion artifact in 2 cases, diffuse hypointensity of the myometrium in 3 cases and distortion of the endometrium by myoma node in 4 cases. On the T1-weighted image, adenomyosis was detected as an enlarged uterus with a smooth external configuration in 20%, within half of which high signal intensity spots representing islands of menstrual hemorrhagic areas were seen. A specific diagnosis of adenomyosis could be made in those cases. On the T2-weighted image, high signal intensity spots (thought to represent heterotopic endometrium) were seen in 46%. On the T2-weighted image, adenomyosis was demonstrated as thickening of the junctional zone (JZ) extending through the myometrium in 80%. Dynamic enhanced MR imaging was performed in 5 cases, 4 of which were accompanied with uterine myoma. Adenomyosis showed sparse contrast enhancement in the early phase, while uterine myoma had no morked enhancement in the early phase but became gradually enhanced in the late phase. In conclusion, MR imaging is useful for detection of adenomyosis. However, when it is difficult to detect adenomyosis or to distinguish it from uterine myoma, dynamic enhanced MR imagings may provide more useful information. (author)

  17. Uterine arterial embolization for uterine leiomyoma: efficacy and clinical outcome

    To determine the efficacy and clinical outcome of uterine arterial embolization as a new approach to the management of uterine leiomyomas. Uterine arterial embolization was performed in 21 patients aged 26-62(mean, 42) years. Twenty of these had menorrhagia, dysmenorrhea, and mass-related symptoms (low abdominal discomfort, backache, urinary frequency, etc.) and one was diagnosed incidentally. Bilateral uterine arteries were selected individually and polyvinyl alcohol and/or gelfoam was used as an embolic material. Nineteen patients were followed up after embolization. Seventeen (89.5 %)reported satisfactory improvement of symptoms and follow-up sonography three months later showed a 58.5 % reduction in mean myoma volume. In 17 patients (89.5 %), the menstrual cycle returned to normal. All patients experienced pain after the procedure and other complications were vaginal bleeding (26.3 %) and fever (23.8 %).

The aim of this study was to assess the possible association between menstrual cycle pattern and occurrence of surgically treated myomas and also to check if depo-medroxyprogesterone acetate (DMPA injection earlier in reproductive life can affect the later occurrence of myomas needing surgical treatment.Methods: In a case–control study in Ardabil, 85 women with definite diagnosis of surgically treated uterine leiomyoma and 154 community controls were enrolled. Possible predictors of myoma including menstrual cycle and menstrual bleeding patterns were assessed. Data were analyzed using SPSS software (SPSS, IBM, Somers, NY. Odds ratios were used as the main statistic in assessing the strength of observed associations.Results: Mean age of the participants was 41.8 ± 8.5 years. Length of menstrual cycle was associated with myoma and a higher likelihood of myoma was observed among those having shorter menstrual cycles (P < 0.05. Number of menstrual bleeding days was also associated with surgically treated myoma and longer bleeding periods increased the likelihood of myoma (P < 0.05. Only one of the eight women who had a history of depo-medroxyprogesterone acetate injections had developed surgically treated uterine leiomyoma and the others belonged to the control group without a history of surgical treatment for uterine leiomyoma.Conclusion: Menstrual cycle pattern is associated with developing leiomyomas requiring surgical treatment

    The purpose of this study was to compare the expression of 3β-hydroxystreroid dehydrogenase (3β-HSD) in the uterus and ovary of healthy dogs and those with cystic endometrial hyperplasia and/or pyometra complex (CEH-pyometra). Eighteen female dogs were included in the study. Eleven bitches with open cervix CEH-pyometra were included in the CEH-pyometra group and seven diestrus bitches in the control group. For immunostaining a rabbit polyclonal, one raised against recombinant human type 2 (adrenal/gonadal) 3β-HSD was used. Progesterone (P4) concentrations were not statistically different between the groups. Strongly stained large interstitial cell groups in the ovarian medulla were observed particularly in CEH-pyometra group although these cells in the control group were weakly or moderately stained and existed singly or paired. The expressions of 3β-HSD in luminal epithelium (42.40 ± 22.40% vs. 18.42 ± 13.15%, P pyometra group than those in the control group. The expression of 3β-HSD in CL was higher (29.38 ± 9.58% vs. 22.94 ± 4.97%) in CEH-pyometra group than that of control group although the differences were not significant (P > 0.05). Similarly, the significant increase in the expression of 3β-HSD in ovarian interstitial cells (33.86 ± 29.44 vs. 1.13 ± 2.97, P pyometra group compared to the control group. The study revealed that 3β-HSD expression in the endometrium of canine CEH-pyometra was significantly high. PMID:27020880

  11. Ultrasonographic findings of Myoma, H-mole and Missed abortion

    Ultrasonography is very important in the diagnosis of various kinds of diseases in Obsterics and Gynecology. It has high diagnostic accuracy in the diagnosis of pelvic masses and widely used for the detection of normal orpathologic pregnancy. But still it is difficult to differentiate degenerated myoma, H-mole and missed abortion by ultrasonography. So the authors analyzed the ultrasonographic findings of 81 patients with myoma(29 cases), H-mole(23 cases), and missed abortion(29 cases) and the results are as follows; 1. Diagnostic accuracy was 8.6% in myoma, 87% in H-mole and 89% in missed abortion. 2. The most typical ultrasonographic finding of myoma was obulated mass contour with nonhomogenous internal echo. 3. The most characteristic finding of H-mole was fine vesicular pattern internal echo with globular enlargement of uterus. 4. The most frequent finding of missed abortion was deformed gestational sac with or without remained fetal echo. 5. Clinical correlation was very important for accurate diagnosis, especially when differential diagnosis was very difficult between myoma with marked cystic degeneration, missed abortion with large distorted gestational sac and H-mole with severe degeneration

    Yoshida, Midori; Inoue, Kaoru; Takahashi, Miwa

    2015-01-01

    Endometrial adenocarcinoma in the uterine corpus is a malignant cancer that occurs in menopausal women and aged rodents. Because of the similarities in pathogenesis and morphology of endometrial adenocarcinoma in rodents and humans, prediction of the modes of action (MOA) in uterine carcinogenesis is important for extrapolation of rodent data to humans. Three MOAs have been accepted as major pathways for uterine carcinogenesis in rodents: 1) estrogenic activity, 2) increased serum 17beta-estr...

  14. Endometrial stromal polyps in rodents: biology, etiology, and relevance to disease in women.

    Davis, Barbara

    2012-04-01

    Endometrial stromal polyps (ESP) are a common spontaneous reproductive tract lesion in the female rat. However, there is limited information concerning the etiology, biology, and significance of these polyps as an end point in toxicology and carcinogenicity studies. This paper reviews relevant literature to address these aspects of ESP with respect to potential relevance to human uterine tumors. Endometrial stromal polyps in rodents appear as age-related lesions. There are only a few chemicals tested for carcinogenicity in rat and mouse cancer bioassays associated with increased incidence of ESP with no common characteristics or mechanism of action. Uterine endometrial polyps that occur in women and the uterine stromal polyps that occur in rodents have distinct characteristics, although both types of uterine lesions are common, benign, and noncancerous. Human endometrial polyps develop from both endometrial and stromal components, whereas rodent polyps develop from the stromal component of the uterus. Endometrial polyps in women are hormone sensitive, but there is no scientific or experimental evidence to date that suggests that uterine stromal polyps in rodents are hormone sensitive. Therefore, based on differences in their etiology and biology, endometrial stromal polyps observed in rodent toxicity and carcinogenicity studies appear to have limited relevance to human endometrial polyps occurring in women.

    2016-03-01

    Endometrial cancer is the third most common gynecologic cancer in the Korea and occurs mainly in menopausal women. Although it can develop in young premenopausal women cancer as well, an attack in the adolescent girl is very rare. A 13-year-old girl visited gynecology department with the complaint of abnormal uterine bleeding. An endometrial biopsy revealed FIGO (International Federation of Gynecology and Obstetrics) grade II endometrial adenocarcinoma. In the treatment of endometrial cancer, conservative management should be considered if the patient is nulliparous or wants the fertility preservation. Therefore, we decided to perform a hormonal therapy and a follow-up endometrial biopsy after progestin administration for eight months revealed no residual tumor. We report a case of endometrial cancer occurred in a 13-year-old girl with a brief review of the literature. PMID:27004208

  16. Torsion of the uterus with myomas in a postmenopausal woman – case study and review of the literature

    Dobrosława Sikora-Szczęśniak

    2014-05-01

    Full Text Available Introduction : Torsion of the uterus is defined as a rotation of more than 45° around the long axis of the uterus; 2/3 of cases are dextrorotations. The extent of rotation usually ranges from 45° to 180°. Objective: The purpose of the article was to present a case study of a postmenopausal woman with uterine torsion and myomas and to review the articles discussing the problem of rotated non-pregnant uterus. Material and methods : The article analyses the course of an extremely uncommon pathology, i.e. uterine torsion in a 67-year-old patient. Laparotomy exposed the uterus with myomas and numerous hemorrhages, rotated by 180° to the right side, size of 350 × 300 × 200 mm and bilateral necrosis of the ovaries. Moreover, we present a review of articles discussing surgical management in case of rotated non-pregnant uterus. Results and discussion: The patient was operated on by a team of gynecologists and surgeons. The uterus was derotated and total hysterectomy with salpingoophorectomy was performed. A fragment of the hepatic oval ligament was excised and periumbilical hernioplasty was performed. The patient was released home on the 10th day following the operation. Conclusions : If women complain of pain located within the small pelvis and abdominal cavity it is necessary to remember that it might result from the torsion of reproductive organs which is an uncommon condition but poses a health or life threat to patients. Surgical treatment of uterine torsion is successful if promptly implemented; in certain cases it is even possible to spare the patient’s fertility.

  19. Spontaneous Uterine Rupture in a Twine Pregnancy at 25-26 Weeks Gestation in a Woman with Previous History of Laparoscopy Myomectomy

    N. Soofizadeh

    2009-07-01

    Full Text Available Introduction: Uterine rupture in pregnancy is rare and often catastrophic with high incidence of fetal and maternal morbidity and mortality. The most common cause of uterine rupture is separation of previous cesarean hysterotomy scar. Other common predisposing factors to uterine rupture are previous traumatizing operations or manipulations such as curettage, perforation, myomectomy and excessive or inappropriate uterine stimulation with oxytocin.Case Report: In this case, spontaneous rupture of uterine at 25-26 weeks gestation (twin pregnancy in a 36 year old woman has been reported(G5P2A2L1. She was hospitalized so that preeclampsia can be rule out for her. She underwent laparoscopic removal of myoma and 3 months later IVF was done for her because of secondary infertility. During hospitalization, suddenly she had mild vaginal bleeding and decreased fetal movement. Emergency sonography reported that the two fetuses died and severe oligohydramnius and myomatosis uterine with the biggest size was 90mm.Conclusion: Try of labor was done for her but she didn't respond to induction and the patient was qualified for cesarean section. During the operation, the rupture of the uterine wall was seen in the site of the previous myomectomy and the two dead fetuses were observed in the abdomen without myoma in the uterin. The myoma that was reported by the sonologist was hematoma and omentoma. Uterine wall was repaired.

  20. Superoxide dismutase and lipid hydroperoxides in blood and endometrial tissue of patients with benign, hyperplastic and malignant endometrium

    Snežana Pejić

    2008-09-01

    Full Text Available Epidemiological and experimental data point to involvement of oxygen derived radicals in the pathogenesis of gynecological disorders, as well as in cancer development. The objective of the present study was to examine changes in activities and levels of copper/zinc superoxide dismutase (CuZnSOD and lipid hydroperoxides (LOOH in blood and endometrial tissue of patients diagnosed with uterine myoma, endometrial polypus, hyperplasia simplex, hyperplasia complex and adenocarcinoma endometrii. The results of our study have shown decreased SOD activities and unchanged SOD protein level in blood of all examined patients in comparison to healthy subjects. Decrease of both SOD activity and level was found in endometrium of patients with hyperplasia simplex, hyperplasia complex and adenocarcinoma in comparison to women with polypus or myoma. LOOH level was elevated in both tissues of patients with hyperplasiaor adenocarcinoma in comparison to healthy subjects or patients with benign diagnosis. Our findings suggest that the decrease in SOD activity and level, as well as the increase in LOOH level, in patients with gynecological disorders, render these patients more susceptible to oxidative damage caused by reactive oxygen species (ROS. An imbalance in ROS formation and SOD level may be important in the pathogenesis and/or perpetuation of tissue damage in gynecological patients. Since evidence suggests that SOD may be a therapy target for cancer treatment, our findings provide a basis for further research and options for clinical applications.Resultados epidemiológicos e experimentais apontam para o envolvimento dos radicais derivados do oxigênio na patogênese das moléstias ginecológicas, assim como no desenvolvimento do câncer.

  2. Postpartum Prolapsed Leiomyoma with Uterine Inversion Managed by Vaginal Hysterectomy

    Kelly L. Pieh-Holder

    2014-01-01

    Full Text Available Background. Uterine inversion is a rare, but life threatening, obstetrical emergency which occurs when the uterine fundus collapses into the endometrial cavity. Various conservative and surgical therapies have been outlined in the literature for the management of uterine inversions. Case. We present a case of a chronic, recurrent uterine inversion, which was diagnosed following spontaneous vaginal delivery and recurred seven weeks later. The uterine inversion was likely due to a leiomyoma. This late-presenting, chronic, recurring uterine inversion was treated with a vaginal hysterectomy. Conclusion. Uterine inversions can occur in both acute and chronic phases. Persistent vaginal bleeding with the appearance of a prolapsing fibroid should prompt further investigation for uterine inversion and may require surgical therapy. A vaginal hysterectomy may be an appropriate management option in select populations and may be considered in women who do not desire to maintain reproductive function.

  3. [Changes in the phosphoinositide metabolism in the blood and tissues of benign and malignant uterine tumors].

    Damirov, M M; Sliusar', N N; Kulakov, V I; Bakuleva, I P; Matruk, T A

    1995-01-01

    Measurements of phosphoinositide levels in the blood, immunocompetent cells, and tumors of 105 patients with uterine myomas, 24 patients with cancer of the corpus uteri, and 17 ones with uterine sarcoma showed that the parameters of phosphoinositide metabolism in the blood of patients with tumors of the uterus reliably differed from those in healthy women. The content of phosphatidylinosites and other phosphoinositide fractions in patients with uterine myomas reliably differed from those in patients with malignant tumors of the uterus, this permitting the use of such measurements in the differential diagnosis. Phosphoinositide mechanism of development of tumors of the uterus is discussed, which is related to the "new" phosphoinositides and secondary messengers directly participating in transfer of cell growth signals.

    In the Western World, endometrial cancer is the most common malignancy of the female genital tract. Endometrioid endometrial carcinoma (EEC or Type I tumour), accounts for approximately 75% of cases. Type II tumours, of which uterine papillary serous carcinoma (UPSC) is the most common subtype, are less common. Since classification as EEC or UPSC has therapeutic and prognostic implications, it is important to make the proper diagnosis. UPSC share their aggressive clinical behaviour and their ...

  5. Uterine stem cells: what is the evidence?

    Gargett, C E

    2007-01-01

    The mucosal lining (endometrium) of the human uterus undergoes cyclical processes of regeneration, differentiation and shedding as part of the menstrual cycle. Endometrial regeneration also follows parturition, almost complete resection and in post-menopausal women taking estrogen replacement therapy. In non-menstruating species, there are cycles of endometrial growth and apoptosis rather than physical shedding. The concept that endometrial stem/progenitor cells are responsible for the remarkable regenerative capacity of endometrium was proposed many years ago. However, attempts to isolate, characterize and locate endometrial stem cells have only been undertaken in the last few years as experimental approaches to identify adult stem/progenitor cells in other tissues have been developed. Adult stem cells are defined by their functional properties rather than by marker expression. Evidence for the existence of adult stem/progenitor cells in human and mouse endometrium is now emerging because functional stem cell assays are being applied to uterine cells and tissues. These fundamental studies on endometrial stem/progenitor cells will provide new insights into the pathophysiology of various gynaecological disorders associated with abnormal endometrial proliferation, including endometrial cancer, endometrial hyperplasia, endometriosis and adenomyosis.

  9. Conventional ultrasonography and color Doppler velocimetry of uterine leiomyomas.

    Caruso, A; Caforio, L; Testa, A C; Pomini, F; Ciampelli, M; Mancuso, S

    1998-01-01

    The role of uterine leiomyomas as causative factor of sterility is controversial. Submucosal myomas, in particular, can interfere with fertility and be associated to obstetric complications as abruption of placenta, post-partum metrorrhagia and puerperal sepsis. With ultrasonography, immediate and long-term information can be drawn on changes in the features of myomas. However, to-date, there are no reliable noninvasive exams to assess the nature and growth pattern of myomas. With Doppler velocimetry in ovarian malignancies a vascularization significantly different from that observed in benign tumors, is detected. It has been hypothesized that within benign tumors, as myomatous masses, tissues with different cell proliferation rates could be characterized by different vascular patterns. In a group of myomas shown to have central arterial vessels at Doppler examination, significant correlations were assessed between resistance indices of analyzed vessels and percentage of cell in the proliferative phase evaluated with cytofluorimetry. The myomatous tissue with high cell proliferation rate seems to have higher vascular resistances. PMID:10191660

  10. Endometrial intraepithelial carcinoma: A case report and brief review

    Ram Manisha

    2008-10-01

    Full Text Available This case report describes the precursor lesion of uterine papillary serous carcinoma (UPSC. A 65-year-old post-menopausal female presented with prolapse and vaginal discharge and underwent a hysterectomy revealing an atrophic endometrium, highly atypical endometrial glands, the lining cells of which showed pseudostratification, hobnailing, a high nuclear to cytoplasmic ratio, and prominent nucleoli. A p53 immunoreactivity score of 8 and a MIB-1 index of 80% was obtained leading to a diagnosis of endometrial intraepithelial carcinoma (EIC. Since serous EIC is commonly associated with extra-uterine serous carcinoma, it is a uniquely aggressive precursor lesion. Molecular studies support the hypothesis that EIC is a precursor of both uterine and extra-uterine invasive serous carcinomas. This is why the treatment protocol for EIC cases is total abdominal hysterectomy (TAH, accompanied by a staging procedure. In our patient, EIC was limited to the endometrium; associated with an excellent clinical outcome.

  11. MRI appearances of benign uterine disease

    Benign uterine disease is a common entity affecting women of all ages. Ultrasound has historically been the predominant imaging method used in the evaluation of benign gynaecological disease, magnetic resonance imaging (MRI) being reserved for use in the staging of malignant uterine and cervical disease. MRI is now increasingly used in the diagnosis of benign uterine disease as well as a tool for problem-solving in cases of diagnostic dilemma. It allows detailed assessment of benign conditions, such as endometrial lesions, leiomyomas, and adenomyosis, and can be helpful in the stratification of patients to different treatment modalities, including surgical resection, uterine artery embolization, and medical therapies. In this article, we review the MRI findings in the common benign uterine diseases

  12. Ultrasonography of Uterine Leiomyomas

    Sabrina Q. Rashid

    2016-03-01

    Full Text Available Leiomyomas or myomas of the uterus, also known as a fibroid uterus, are the most common tumors of the uterus. They are benign neoplasms of smooth muscle origin with various degrees of fibrous connective tissue. These tumors can develop in any part of the female genital tract where there is smooth muscle or fibrous tissue, even in the ovary, broad ligament, and vagina. They need to be differentiated from adenomyosis and intracavitary polyps. They mostly remain asymptomatic but sometimes they cause significant morbidity. In such situations, hysterectomy or other surgical intervention is indicated. On ultrasonography, most uterine leiomyomas typically appear as well-defined, solid masses. Their echogenicity is usually similar to that of the myometrium, but sometimes they are hypoechoic. They often show some posterior acoustic shadowing. Variants of leiomyomas occur when they undergo cystic degeneration, hyalinization, or calcification. In such situations, determining a diagnosis is sometimes difficult. Magnetic resonance imaging can be used in this situation for an accurate diagnosis.

  13. Genetic susceptibility to breast and endometrial cancer

    Wedrén, Sara

    2004-01-01

    Hormones are central in the carcinogenic process in the breast and in the uterine epithelium. Individual genetically determined variation in the response to hormonal influence may alter susceptibility to breast and endometrial cancers. Many small studies of this hypothesis have generated inconclusive results. Since the effect of any genetic variant is expected to be modest, large studies are needed to draw reliable conclusions. Also, there may be interaction between genetic ...

  14. MACROGLOBULIN PROTEINS IN ADENOMYOSIS AND UTERINE LEIOMYOMA

    V. N. Zorina

    2015-06-01

    Full Text Available We studied blood contents of alpha-2-macroglobulin (α2-MG, pregnancy-associated alpha2-glycoprotein (PAG, and their immune complexes with IgG in healthy female controls, as well as in women with adenomyosis, females with uterine myoma (with or without proliferation, and in cases of a leiomyoma combined with adenomyosis. We found that the most pronounced reduction in α2-MG concentrations was observed in leiomyoma, but they were not decreased in a combination of myoma/ adenomyosis. The PAG levels, a known proliferation marker, have been shown to be increased only in the combined disorder. The amounts of immune complexes (α2-MG/IgG and PAG-IgG were more significantly increased in leiomyoma complicated by adenomyosis. Correlative interrelationships between the studied parameters differed between normal and pathological conditions. Given that α2-MG and PAG are immunoregulatory proteins being actively involved in proliferative and inflammatory processes, we may assume that they participate in pathogenesis of immune-related uterine diseases, and, especially, in combined disorders.

  15. Morphometric evaluation of endometrial blood vessels

    Makhija Divya

    2008-07-01

    Full Text Available Five hundred endometrial specimens were studied to document the changes in blood vessels in various phases of menstrual cycle, menstrual disturbances and in unexplained infertility. Sixty-three cases were taken as control and 437 cases as study group which included cases of dysfunctional uterine bleeding (DUB, endometrial polyps, fibroids, adenomyosis, infertility and atrophic endometrium. Using light microscopy, the vascular morphology was studied. The blood vessels were concentrated more in basal layer in the proliferative phase and in functional layer in the secretory phase. Cases of complex hyperplasia and pill endometrium had significantly higher vessel concentration. Congestion and dilatation of blood vessels were significantly higher in cases of DUB. The present study showed a positive correlation between endometrial angiogenesis and menstrual disorders. The alteration in blood vessel morphology has significant role in prognosis and in various anti-angiogenic therapies.

    Full Text Available Endometrial stromal nodule (ESN is the least common of the endometrial stromal tumors. They are rare neoplasms which are diagnosed in most instances by light microscopy. Although such nodules are benign, hysterectomy has been considered the treatment of choice to determine the margins of the tumor required for diagnosis and to differentiate it from invasive stromal sarcoma Whose prognosis is totally different. We report a case of a 45 years old woman, with presurgical diagnosis of adnexal mass or uterine tumor. She underwent a total abdominal hysterectomy. Pathologic examination revealed an endometrial stromal nodule. Through this observation, we insist on the fact that the ESNs are rare and benign entities which must be differentiated from the other invasive malignant stromal tumors; this can change the final prognosis.

  18. Diffusion-Weighted Magnetic Resonance Imaging of Endometrial Cancer: Differentiation from Benign Endometrial Lesions and Preoperative Assessment of Myometrial Invasion

    Takeuchi, M.; Matsuzaki, K.; Nishitani, H. (Dept. of Radiology, Univ. of Tokushima, Tokushima (Japan))

    2009-10-15

    Background: Uterine endometrial cancer is the most common gynecologic malignancy, and benign endometrial hyperplasia or polyps should be differentiated from endometrial cancer. In evaluating endometrial cancer on magnetic resonance imaging (MRI), the assessment of the depth of myometrial invasion is important because it closely correlates with the patient's prognosis. Purpose: To verify the feasibility of diffusion-weighted magnetic resonance imaging (DWI) to distinguish benign and malignant endometrial lesions, and to evaluate myometrial invasion of endometrial cancer. Material and Methods: Sixty-seven endometrial lesions including 45 cancers and 22 benign lesions (hyperplasia and polyps) were evaluated by DWI with apparent diffusion coefficient (ADC) measurement. The staging accuracies of DWI and gadolinium-enhanced T1-weighted images in the assessment of myometrial invasion were evaluated in 33 patients with endometrial cancer. Results: The ADC values (x10-3 mm2/s) in cancer and benign lesions were 0.84+-0.19 and 1.58+-0.36, respectively (P<0.01). The staging accuracy (superficial or deep myometrial invasion) was 94% for DWI and 88% for gadolinium-enhanced T1-weighted images. Coexisting adenomyosis and infiltrative myometrial invasion caused staging errors on gadolinium-enhanced T1-weighted images, whereas DWI could demonstrate the tumor extent correctly. Conclusion: DWI provides helpful information in evaluating benign and malignant endometrial lesions.

The staging accuracies of DWI and gadolinium-enhanced T1-weighted images in the assessment of myometrial invasion were evaluated in 33 patients with endometrial cancer. Results: The ADC values (x10-3 mm2/s) in cancer and benign lesions were 0.84±0.19 and 1.58±0.36, respectively (P<0.01). The staging accuracy (superficial or deep myometrial invasion) was 94% for DWI and 88% for gadolinium-enhanced T1-weighted images. Coexisting adenomyosis and infiltrative myometrial invasion caused staging errors on gadolinium-enhanced T1-weighted images, whereas DWI could demonstrate the tumor extent correctly. Conclusion: DWI provides helpful information in evaluating benign and malignant endometrial lesions

    Cases of gynecological tumor mainly uterine benign and malignant tumors were evaluated using /sup 201/Thallium-Chloride (/sup 201/Tl-Cl) after intravenous injection. The positive scans of 100% in 42 cases of uterine myoma including 29 cases of leiomyoma, 8 cases of adenomyosis and 5 cases of combined type myoma, also 100% in 8 cases of body cancer indicating adenocarcinoma and 25% in 12 cases of cervical cancer indicating squamous cell carcinoma were observed. The smallest focal lesion for the positive scans was needed approximately more 5 cm in diameter in the cases of leiomyoma. The most accumulation of activities was shown in adenomyosis or adenocarcinoma with much adenoid structure in the pathological study. Accumulation of /sup 201/Tl in uterine benign and malignant tumors was suggested the analog of potassium. The mechanism of tumor affinity was correlated to perfusion volume and the acceleration of the potassium metabolism in a tumor. On the other hand, we suggested the diagnosis of the malignant uterine tumor should be attended due to /sup 201/Tl accumulation also in the benign uterine tumor. The uterine scanning using /sup 201/Tl-Cl was acknowledged to be very useful and safe indicating early detection at 20 minutes after the injection, (non-traumatic procedure and non-visualized bone tissues). In conclusion, this radioisotopical procedure was indicated to be a high value screening examination in the diagnosis of uterine tumor.

  2. Development of uterine neoplasms following radiotherapy for carcinoma of uterine cervix: a clinical evaluation of 47 patients

    Objective: To analysis the characteristics and clinical features of uterine neoplasms developed after radiation therapy for cervical carcinoma. Methods: The clinical data of 47 patients of uterine neoplasm developed following radiotherapy for uterine cervical carcinoma were retrospectively reviewed. Results: The median age on diagnosis of uterine neoplasms was 62 years (range 38-77), and the median latency from the initial therapy to the development of uterine neoplasm was 14 years (range 5-35). Thirty of 47 patients had endometrial carcinoma, of which 3 were uterine papillary serous carcinoma(UPSC). Seventeen of 47 patients had uterine sarcoma, all of which were carcinosarcoma. The distribution by stage, grade, and histology of 30 patients with endometrial carcinoma was: stage Ib, 1 patient; stage Ic, 2 patients; stage II, 6; stage III a, 4; stage III b, 2; stage III c, 11; stage IV, 4; grade 1, 2 patients; grade 2, 9; grade 3 (include 3 UPSC patients), 17; unknown grade, 2; endometriod, 27; UPSC, 3. Seven of 30 patients with en- dometrial carcinoma deleloped recurrence, at median time of 24 months. Their median survival time was 26 m. The overall 3- and 5-year survival rate was 60% and 38%, respectively. Of the 17 patients with uterine sarcoma, the median survival was 10 months. Six patients developed recurrence, at a median time of 9 months, and their median survival was 6 months. The overall 3- and 5-year survival rate was 12% and 0, respectively. Conclnsions: The main uterine neoplasm developed after radiotherapy for uterine cervical carcinoma is endometrial carcinoma, of which there is a preponderance of high-risk histological subtype and poor prognosis. Most of the uterine sarcoma which occur following radiation therapy for uterine cervical carcinoma is carcinosarcoma and its prognosis is very poor. (authors)

    Implantation failure is considered as a major cause of infertility in women with recurrent pregnancy loss (RPL) and in otherwise healthy women with unexplained infertility. Preliminary data in primates suggested that relaxin (RLX) is involved in endometrial preparation for implantation. In a prospective observational study, the endometrial RLX receptor (LGR7) expression was assessed in three groups of patients with regular ovulatory cycle and normal uterine cavity: 23 with RPL (Group A), 23 with unexplained infertility undergone at least three cycles of failed in vitro fertilization (IVF) reporting good oocyte and embryo quality (Group B), 23 with proven fertility (Group C). Assessment of LGR7 expression was performed with both polymerase chain reaction (PCR) analysis and immunohistochemistry on endometrial samples obtained with hysteroscopic biopsy performed in the secretory phase of the menstrual cycle. Endometrial LGR7 was less expressed in group A and B versus C, both by PCR analysis (p = 0.024) and immunohistochemistry. The decreased expression of the endometrial RLX receptor in women with implantation failures, both in vitro fertilization failure and recurrent pregnancy loss, suggests that RLX may play a crucial role in the structural and functional changes of the endometrium during the window of implantation.

    2013-01-01

    Abnormal Uterine Bleeding (AUB) is one of the most common health problems encountered by women. It affects about 20% women of reproductive age, and accounts for almost two thirds of all hysterectomies. Gynaecologists are often unable to identify the cause of abnormal bleeding even after a thorough history and physical examination. Diagnostic evaluations and treatment modalities have been evolving over time. The onus in AUB management is to exclude complex endometrial hyperplasia and endometri...

    Bovine postpartum uterine disease, metritis, affects about 40% of animals and is widely considered to have a bacterial aetiology. Although the gamma herpesvirus BoHV-4 has been isolated from several outbreaks of metritis or abortion, the role of viruses in endometrial pathology and the mechanisms of viral infection of uterine cells are often ignored. The objectives of the present study were to explore the interaction, tropism and outcomes of BoHV-4 challenge of endometrial stromal and epithel...

  7. Endometrial aspiration biopsy: a non-invasive method of obtaining functional lymphoid progenitor cells and mature natural killer cells.

    McMenamin, Moya

    2012-09-01

    The aim of this study was to compare the efficacy of endometrial aspiration biopsy (EAB) with the more traditional dilatation and curettage (D&C) for the procurement of lymphoid progenitor cells and uterine natural killer (NK) populations in endometrial tissue. This prospective observational study conducted in a tertiary referral university hospital examined endometrium obtained from 32 women admitted for laparoscopic gynaecological procedures. Each participant had endometrium sampled using both EAB and D&C. Both methods were assessed as a source of uterine NK and lymphoid progenitor cells. Similar proportions of mature CD45+CD56+ NK cells (range 25.4-36.2%) and CD45+CD34+ lymphoid progenitors (range 1.2-2.0%) were found in tissue obtained using both EAB and D&C. These cells were adequate for flow cytometric analysis, magnetic bead separation and culture. Colony formation by the CD34+ population demonstrated maturational potential. Tissues obtained via endometrial biopsy and D&C are equivalent, by analysis of uterine NK and lymphoid progenitor cells. The aim of this study was to compare two methods of endometrial sampling - endometrial aspiration biopsy and traditional dilatation and curettage - for the procurement of haematopoietic stem cells and uterine natural killer (NK) populations in endometrial tissue. Thirty-two women who had gynaecological procedures in a tertiary referral hospital participated in this study and had endometrial tissue collected via both methods. Similar populations of mature NK cells and haematopoietic stem cells were found in tissue obtained using both endometrial aspiration biopsy and dilatation and curettage. Tissue obtained via endometrial aspiration biopsy was adequate for the culture and growth of haematopoietic stem cells. We conclude that tissue obtained via endometrial biopsy and dilatation and curettage is equivalent, by analysis of uterine NK and haematopoietic stem cells using flow cytometry. This has implications for further

    Full Text Available Background: Abnormal uterine bleeding is one of the commonest complaints in women and when it occurs without organic lesions like tumor, inflammation, it is called as dysfunctional uterine bleeding. Aim of current study was to find out the histopathological pattern of endometrium in Abnormal Uterine Bleeding (AUB also to study organic causes of AUB. Methods: Specimens received as endometrial curettage and hysterectomy specimens were studied followed by correlation of histopathology with age and clinical presentation. Results: The patients were mainly from the age group of 30-49 years (74.24%. The most common menstrual disorder was menorrhagia (46.86%. In dysfunctional uterine bleeding the most common histological pattern of endometrium includes proliferative endometrium (22.8% followed by endometrial hyperplasia (19.40%, atrophic endometrium (7.16%, secretory endometrium (5.97%, irregular shedding [1.80%], irregular ripening (1.20% and anovulatory endometrium (0.59%. Organic lesions encountered in AUB cases were leiomyoma (17.92%, endometrial polyp (1.79%, endometrial carcinoma (1.50%, endometriosis (0.59% and choriocarcinoma (0.29%. Conclusion: It is important to know the histological pattern of the endometrium like proliferative endometrium, endometrial hyperplasia, atrophic endometrium, secretory endometrium, irregular ripening and shredding and organic lesions in patients diagnosed as AUB in different age groups since recognition of these conditions will help and will avoid further complications.

  9. Achados histeroscópicos em mulheres na pós-menopausa com diagnóstico de espessamento endometrial por ultra-sonografia transvaginal Hysteroscopic findings in postmenopausal women with endometrial thickening diagnosed by transvaginal ultrasound

    Adriana Bittencourt Campaner

    2004-02-01

    with hysteroscopic evaluation was performed in 121 postmenopausal women, with endometrial thickening diagnosed through transvaginal ultrasonography. In 98 women there was no history of hormonal replacement therapy, while the remaining 23 received different types of hormone; 55 patients complained of vaginal bleeding and the remaining did not present this condition. The endoscopic examinations were performed in the outpatient clinic, using a 4 mm rigid hysteroscope. For uterine cavity distention carbon dioxide (CO2 was used. Biopsy was performed in all patients, with a 3 mm Novak type curette, and the collected material was submitted to a histopathological study. RESULTS: endometrial thickening varied from 6 to 38 mm, with a mean of 10.7 ± 5.3 mm. The hysteroscopic findings were: polypoid lesion in 51 patients (42.1%; atrophic endometrium in 15 patients (12.4%; senile synechia in 15 patients (12.4%, focal thickening in 13 patients (10.7%; cerebroid lesion in 6 patients (5.0%; proliferative endometrium in 5 patients (4.1%; mucus in 5 patients (4.1%; myoma in 4 patients (3.3%; secreting endometrium in 3 patients (2.5%; endometrial hyperplasia in 3 patients (2.5%; and cystic atrophy in 1 patient (0.8%. Correlation between hysteroscopic findings and cytopathology was observed in 30 of 51 cases of polypoid lesion, in 12 of 15 cases of atrophic endometrium and in all cases in which the diagnosis of endometrial hyperplasia or adenocarcinoma was suspected. CONCLUSION: in the majority of the patients, the hysteroscopic examinations revealed that there was no genuine endometrial thickening but rather other types of lesion in the uterine cavity.

    Background. Polycystic ovary syndrome (PCOS) is associated with chronic oligo-anovulation and high circulating sex hormone levels. Women with PCOS have an increased risk of developing endometrial cancer. In anovulatory women with PCOS a positive relationship between endometrial thickness and endometrial hyperplasia has been observed. Uterine peristalsis, which has been suggested to be of importance for female fertility, has not previously been studied in PCOS. Purpose. To assess whether women with PCOS have altered endometrial thickness, uterine wall morphology, and peristalsis. Material and Methods. In this prospective case-control study 55 women with PCOS (mean age, 29.5 years {+-} 4.5 SD) and 28 controls (27.6 {+-} 3.2) were examined using magnetic resonance imaging (MRI), assessing thickness of endometrium, junctional zone (JZ), and myometrium, and evaluating the occurrence, frequency (waves/min), strength (amplitude), pattern, and direction of peristalsis. Uterine morphology was also assessed by transvaginal ultrasonography (TVUS). Results. The endometrium was thinner in PCOS with oligo-amenorrhea compared to controls, also after adjustments for age and BMI (adjusted P = 0.043). There was no difference in thickness of the JZ or the myometrium in cases versus controls. Uterine peristalsis was less commonly observed in women with PCOS than in controls (adjusted P = 0.014). Conclusion. There were no differences in myometrial morphology between PCOS and controls, but the endometrium was thinner in PCOS with oligo-amenorrhea. Based on cine MRI, uterine peristalsis was less common in PCOS than in controls.

    Background Ultrasound (US) is a popular method in the diagnosis and treatment of uterine leiomyomas, but the lack of accuracy greatly limits its application. Recently, microbubble enhancement technique affords direct depiction of tumor neovascularity and establishes a more precise vascular map of the tumor. This study was undertaken to describe the distribution patterns of SonoVue, a second-generation contrast agent, in the micrecirculation of uterine leiomyomas, and to investigate the potential use of contrast-enhanced ultrasound (CEUS) in the characterization and treatment of uterine leiomyomas.Methods Ninety-six patients with uterine leiomyomas were enrolled in this study. The CEUS was performed using cadence pulse sequencing technique (CPS) and SonoVue. Enhancement patterns of different lesions were observed.The diagnostic accuracy of CEUS was compared with that of conventional ultrasound.Results After contrast injection, vessels of macro- and micro-circulation of the myoma first appeared, followed by the normal myometrium and finally the endometrium. During the washout phase, the myoma exhibited homogeneous enhancement followed by apparent hypoenhancement. The margin of the tumor was depicted clearly. There was no agent perfusion in the benign degenerative or necrotic area. However in sarcomas degeneration, the feeding vessels appeared markedly earlier than those in myometrium. In addition, the tumor exhibited heterogeneous hyperenhancment with no agent perfusion in the center and no membraniform sign was observed in the late phase. In subserous andsubmucous leiomyomas, the feeding arteries in the pedicle arising from the uterine could be seen. In this study, the diagnostic accuracy of CEUS and conventional US for uterine leiomyomas was 96.7% (160/165) and 82.4% (136/165)respectively.Conclusions CEUS can provide a precise description of the leiomyomas vascularization. The specific enhancement pattern may be helpful for the characterization, treatment choice

    2013-01-01

    Embryo implantation is a critical step of human reproduction,which depends on the synchronization between embryo development and establishment of endometrial receptivity. Endometrial receptivity refers to the ability of the uterine lining to accept and accommodate a nascent embryo. A related concept regarding a "window of implantation" that means a period of receptivity when endometrium-embryo interactions occur,which also focuses our collective understanding of pregnancy loss and infertility. Complex mechanism is involved in the regulation of endometrial receptivity. We have learned some anatomical and functional markers of endometrial receptivity by using morphology, secretomics and endometrial biopsy study. The changes of endometrial morphology include the changes of morphocytology, histomorphology and sonomorphology. Timely regulation of the expression of a number of complex molecules, such as hormones, cytokines and growth factors,also reflect the state of endometrium. So, proper assessment of endometrial receptivity could instruct our early intervention in assisted reproduction technology(ART). There are several intervening measures such as endometrial scratch, immunoglobulin or husband blood lymphocyte antibodies injection, uterine perfusion and so on. Some researches found that uterine perfusion with HCG 500 IU/ml or granulocyte colony-stimulating factor(G-CSF)300 μg/ml could be a new and potential intervention for improving the endometrial receptivity,but it still needs lots of clinical trials to prove out.

    The pathogenesis of early-onset endometriosis has recently been revisited, sparked by the discovery of endometrial stem/progenitor cells and their possible role in endometriosis, and because maternal pregnancy hormone withdrawal following delivery induces uterine bleeding in the neonate. The neonatal uterus has a large cervix to corpus ratio which is functionally blocked with mucous, supporting the concept of retrograde shedding of neonatal endometrium. Only 5% show overt bleeding. Furthermore, the presence of endometriosis in pre-menarcheal girls and even in severe stage in adolescents supports the theory that early-onset endometriosis may originate from retrograde uterine bleeding soon after birth. Endometrial stem/progenitor cells have been identified in menstrual blood suggesting that they may also be shed during neonatal uterine bleeding. Thus, we hypothesized that stem/progenitor cells present in shedding endometrium may have a role in the pathogenesis of early-onset endometriosis through retrograde neonatal uterine bleeding. During the neonatal and pre-pubertal period, shed endometrial stem/progenitor cells are postulated to survive in the pelvic cavity in the absence of circulating estrogens supported by niche cells also shed during neonatal uterine bleeding. According to this hypothesis, during thelarche, under the influence of rising estrogen levels, endometrial stem/progenitor cells proliferate and establish ectopic endometrial lesions characteristic of endometriosis. This New Research Horizon review builds on recent discussions on the pathogenesis of early-onset endometriosis and raises new avenues for research into this costly condition. PMID:24674992

  1. Uterine contractions evaluated on cine MR imaging in patients with uterine leiomyomas

    Purpose: Submucosal leiomyoma is one of the most recognized causes of infertility and habitual abortion. The purpose of this study is to evaluate uterine peristalsis, a cycle-related inherent contractility of uterus probably responsible for sperm transport and conservation of pregnancy, in patients with uterine leiomyomas using cine magnetic resonance (MR) imaging. Materials and methods: Study population consisted of 26 female patients (age range: 19-51 years, mean: 41 years), in which 16 patients had submucosal leiomyomas and 10 patients had intramural or subserosal leiomyomas. We prospectively performed MR imaging of the midsagittal plane of uterus using 1.5 T magnet (Symphony, Siemens Medical Systems) with a body array coil, and obtained 60 half-Fourier acquisition single shot turbo spin echo (HASTE) images (Echo time=80 ms, FOV=300 mm, slice thickness 5 mm, matrix 256x256) within 2 min, and displayed them on cine mode at 12x faster than real speed. Evaluated were peristaltic movements at the endometral-myometrial junction and focal myometrial movements, adjacent to leiomyomas, regarding presence, direction, frequency, and conduction. Results: The peristaltic movements were identified in 12/16 patients with submucosal lesions and 10/10 with other leiomyomas. The frequency and direction were cycle-related. Loss of peristalsis was noted adjacent to submucosal myomas in 4/12 patients, but was not in others. Focal myometrial movements were noted in 9/16 patients with submucosal myomas, but not in others. Conclusions: Uterine peristaltic movements were partly interrupted by submucosal leiomoymas, but not by myometrial or subserosal leiomyomas. Loss of peristalsis and focal myometrial movements was noted only adjacent to submucosal leiomyomas.

    Purpose: Submucosal leiomyoma is one of the most recognized causes of infertility and habitual abortion. The purpose of this study is to evaluate uterine peristalsis, a cycle-related inherent contractility of uterus probably responsible for sperm transport and conservation of pregnancy, in patients with uterine leiomyomas using cine magnetic resonance (MR) imaging. Materials and methods: Study population consisted of 26 female patients (age range: 19-51 years, mean: 41 years), in which 16 patients had submucosal leiomyomas and 10 patients had intramural or subserosal leiomyomas. We prospectively performed MR imaging of the midsagittal plane of uterus using 1.5 T magnet (Symphony, Siemens Medical Systems) with a body array coil, and obtained 60 half-Fourier acquisition single shot turbo spin echo (HASTE) images (Echo time=80 ms, FOV=300 mm, slice thickness 5 mm, matrix 256x256) within 2 min, and displayed them on cine mode at 12x faster than real speed. Evaluated were peristaltic movements at the endometral-myometrial junction and focal myometrial movements, adjacent to leiomyomas, regarding presence, direction, frequency, and conduction. Results: The peristaltic movements were identified in 12/16 patients with submucosal lesions and 10/10 with other leiomyomas. The frequency and direction were cycle-related. Loss of peristalsis was noted adjacent to submucosal myomas in 4/12 patients, but was not in others. Focal myometrial movements were noted in 9/16 patients with submucosal myomas, but not in others. Conclusions: Uterine peristaltic movements were partly interrupted by submucosal leiomoymas, but not by myometrial or subserosal leiomyomas. Loss of peristalsis and focal myometrial movements was noted only adjacent to submucosal leiomyomas. These findings are considered to represent dysfunctional contractility, and may be related with pregnancy loss.

    Magnetic resonance imaging (MRI) is the method of choice in staging endometrial cancer. Using MRI early tumor invasion (stage IA) can be differentiated from a deep tumor growth (stage IB) of the myometrium with reported sensitivities of 85-95%.Tumor invasion of the uterine cervix can be depicted with a sensitivity of 80% and specificity of 96%. In demonstrating lymph node metastases MRI shows a sensitivity of 50%, a specificity of 95% and and accuracy of 90%. These diagnostic criteria are decisive for the choice of therapy procedures. So a simple hysterectomy will be performed in early stage IA disease while an extended surgical procedure with pelvic lymphadenectomy and radiotherapy will be considered in advanced stages IB and II disease. Vaginal ultrasound shows lower values in tumor staging with accuracies of 73-95%. Staging accuracies of computed tomography also show lower results with 61-76%. For planning radiotherapy and detection of cancer recurrence MRI is the most valuable tool. (orig.) [German] Fuer die Stadieneinteilung des Endometriumkarzinoms ist die Magnetresonanztomographie Methode der Wahl. Die Sensitivitaeten zur Differenzierung einer oberflaechlichen (Stadium IA) von einer tiefen myometrialen Invasion des Tumors (Stadium IB) liegen bei 85-95%, bei Spezifitaeten von 80-85%. Eine Infiltration der Zervix (Stadium II) kann mit Sensitivitaeten von 80% und Spezifitaeten von 96% nachgewiesen werden. Bei der Detektion von Lymphknotenmetastasen liegen die Sensitivitaeten der MRT bei 50%, bei Spezifitaeten von 95% und Treffsicherheiten von 90%. Die genannten diagnostischen Kriterien bestimmen das therapeutische Vorgehen. Werden fruehe Stadien mit einfacher Hysterektomie behandelt, erfordern die Stadien IB und II kombinierte erweiterte chirurgische Techniken und eine Radiotherapie. Die Treffsicherheiten des vaginalen Ultraschalls (73-93%) und der Computertomographie (61-76%) fuer die Stadieneinteilung des Tumors liegen deutlich niedriger als die Werte fuer

    Full Text Available Angioleiomyomas are relatively common neoplasms in s kin and superficial planes of extremities (89%, head (48% and trunk (14%. Thes e tumours are extremely rare in uterus with very few cases described in the literature. Th ese cases have been described with varied names like angiomyoma, angioleiomyoma, or vascular leiomyoma. There is no description of angioleiomyoma as an entity or as a variant of leio myoma in the latest WHO classification of uterine tumours. There is a mention of vascular lei omyoma as a differential diagnosis of hemangioma under rare mesenchymal tumors but no des cription provided. A proposal has been made by Glenn Mc Cluggage et.al that angioleiomyoma should be included among the b enign leiomyoma variants in the next WHO classification.

  5. Ultrasound in assisted reproduction: a call to fill the endometrial gap.

    Hershko-Klement, Anat; Tepper, Ronnie

    2016-06-01

    Ultrasound offers essential details and an overall view of the anatomic features of the reproductive organs, as well as physiologic assessment. There is still a great gap, however, in our understanding and interpretation of endometrial sonographic findings. Endometrial thickness, growth, and sonographic patterns have been repeatedly tested and compared with pregnancy rates in IVF cycles, yielding conflicting results. Generally, the data accrued so far suggest refraining from clinical decisions based solely on endometrial thickness. The three-layer ultrasound pattern reflects normal follicular/proliferative dynamics, and its presence in the pre-hCG period was reported to carry a better outcome: Significantly higher clinical pregnancy rates were found in patients with this pattern on the day of hCG administration among IVF cohorts. Subendometrial contractility (endometrial "waves") offers a tool that can be used in cases of repeated implantation failure in patients reporting cramps around the planned time of embryo transfer, or as a reassuring modality to assess uterine quiescence during preparations for embryo transfer. We support the creation of an integrated endometrial score incorporating conservative endometrial measurements, endometrial-myometrial junction studies, and endometrial contractility, as well as new concepts that remain to be tested, such as endometrial surface area. Such scores may enable us to improve the effectiveness of endometrial ultrasound imaging in the clinical setting. PMID:27140291

    New diagnostic approaches are required to recognize early canine hypofertility or infertility. We suggest that the identification of different cytologic types, cellular aspects, and nuclear features of the endometrial epithelial cells may be suitable for this purpose. This study was performed on the bitch (Canis familiaris) during the physiologic reproductive cycle and in uterine diseases. We also applied computerized cytomorphometry to evaluate nuclear area, perimeter, diameter, density, aspect, and roundness of endometrial epithelial cells in healthy dogs (N=35) at different stages of the reproductive cycle (before puberty, during proestrus, estrus, diestrus, and anestrus) and in bitches affected by uterine disorders (N=10). The stage of the estrous cycle was determined by vaginal cytology and progesterone evaluation and also confirmed by clinical and histologic observations. Samples for endometrial cytology were collected in vivo by uterine flushing with transcervical uterine cannulation. After uterine sampling, each dog underwent OHE or uterine stump revision. Cytologic analyses were compared with histologic examinations to verify the uterine condition. The uterine cellular population was represented by endometrial epithelial cells, erythrocytes, neutrophils, lymphocytes, eosinophils, macrophages, plasma cells, and cervical or incidental vaginal cells. Bacteria and amorphous material were observed. The proportion of different cells and nuclear features in the cytologic samples varied throughout the stages of the reproductive cycle and between normal and pathologic uterine conditions. The computer-assisted nuclear morphometry, performed in cytologic specimens by means of the six nuclear parameters chosen to evaluate the endometrial epithelial cell population, proved to be useful for determining the stage of the reproductive cycle. Furthermore, this system was demonstrated to be a valid support to diagnose and distinguish uterine disorders. PMID:20116837

    The aim of this study was to evaluate endometrial echotexture changes on ultrasonographic digital images during subclinical endometritis using a computer-assisted image analysis program. Endometrial samples were collected from 140 Brown Swiss cows (days in milk = 35 ± 3) using a cytobrush method and classified as having a non-inflamed uterus (n = 66) and uterus with acute (n = 42), subacute (n = 21), and chronic (n = 11) inflammations. The mean cellular infiltration density was 0%, 31 ± 5%, 37 ± 6%, and 16 ± 8% for cows with non-inflamed uterus and cows with acute, subacute, and chronic uterine inflammations (P endometritis in cows.

  8. Uterine stem cells--promise and possibilities.

    Pal, Lubna

    2015-11-01

    A fraction of cells residing in the uterine endometrium exhibit functional pluripotent potential, allowing them to be classified as adult stem cells. While the physiological relevance of this cell population is mostly conjectural at this juncture, uterine endometrial stem cells (UESC's) may underline pathogenesis of certain common gynecological disorders, such as endometriosis and adenomyosis. The ease of access and harvesting of UESC's and the diverse differentiation potential of this cell population has identified the uterine endometrium as a valuable source of autologous stem cells that can be harnessed through judicious application of principals of regenerative medicine. This mini review offers a glimpse into the journey, and an introduction to the spectrum of disorders that UESC's have the potential of impacting. PMID:26297687

    2016-03-01

    Carcinosarcoma arising from uterine adenomyosis is extremely rare. We encountered such a patient and herein provide a review of the literature. A 56-year-old woman was referred for a huge pelvic tumor, suspected to be an advanced uterine leiomyosarcoma. Intraoperative inspection revealed a mass, mainly located in the uterine myometrium, invading the uterine serosa. The tumor had previously spontaneously ruptured and disseminated to the pelvic cavity. Pathological and immunohistochemical examination revealed an infiltrative pattern of biphasic tumor cells composed of endometrioid adenocarcinoma and a nonepithelial component with rhabdomyosarcomatous differentiation. Benign endometrial glands with stromal cells were found adjacent to the area of the carcinosarcoma. The endometrium and both ovaries and fallopian tubes were microscopically free of tumor cells. The final diagnosis was heterologous type carcinosarcoma with rhabdomyosarcomatous differentiation, originating from uterine adenomyosis. PMID:26663238

  10. Persistence of endometrial activity after radiation therapy for cervical carcinoma

    Radiation therapy is a proved treatment for cervical carcinoma; however, it destroys ovarian function and has been thought to ablate the endometrium. Estrogen replacement therapy is often prescribed for patients with cervical carcinoma after radiation therapy. A review of records of six teaching hospitals revealed 16 patients who had endometrial sampling for uterine bleeding after standard radiation therapy for cervical carcinoma. Fifteen patients underwent dilatation and curettage, and one patient underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy when a dilatation and curettage was unsuccessful. Six patients had fibrosis and inflammation of the endometrial cavity, seven had proliferative endometrium, one had cystic hyperplasia, one had atypical adenomatous hyperplasia, and one had adenocarcinoma. Although the number of patients who have an active endometrium after radiation therapy for cervical carcinoma is not known, this report demonstrates that proliferative endometrium may persist, and these patients may develop endometrial hyperplasia or adenocarcinoma. Studies have indicated that patients with normal endometrial glands have an increased risk of developing endometrial adenocarcinoma if they are treated with unopposed estrogen. Patients who have had radiation therapy for cervical carcinoma should be treated with estrogen and a progestational agent to avoid endometrial stimulation from unopposed estrogen therapy

    2014-07-01

    Full Text Available Background: Small intrauterine lesions such as septum, adhesion, polyp, and submucous myoma may be of greater significance in causing implantation failure, poor reproductive performance and abnormal uterine bleeding. We studied effectiveness of therapeutic intervention through operative hysteroscopy in improvement of pregnancy outcome and cessation of abnormal uterine bleeding (AUB in women with pregnancy and fertility problems. Materials and Methods: This prospective cohort study was performed between 2003- 2009 on 65 patients with primary or secondary infertility, recurrent abortion and structural uterine lesions reported in sonography or hysterosalpingography. After hysteroscopic metroplasty, myomectomy, adhesiolysis and polypectomy under laparoscopic guide, we evaluated reproductive outcome, early and late complications, one year after surgery. Results: Among all patients with recurrent abortion, 6 patients (75% complete their pregnancy successfully. Our results showed that pregnancy rate after metroplasty was 58%. Reproductive outcome was poor after myomectomy and adhesiolysis. Abnormal uterine bleeding was improved in 62% of patients. Conclusion: Structural uterine lesions has been assumed to cause infertility, while several studies have shown very poor reproductive performance with high miscarriage and low term delivery rates when malformation is not treated. We show improvement in conceptional outcome and in patient’s chief complaints after hysteroscopy surgery of these anomalies.

    Full Text Available Approximately 24 million women in Europe and more than 20 million women in North America mainly between the ages of 35 and 55 years suffer from uterine myomas; this is 40% of all women in this age group. Myoma-derived symptoms manifest themselves by strong uterine bleeding, anaemia, pain and infertility. Thereby, the quality of life of many women is impaired to a high extent and in many cases this ultimately leads to hysterectomy.br Two randomised double-blind studies published in 2012 demonstrated the efficacy of the progesterone receptor modulator ulipristal acetate in the treatment of uterine myomas in women who were eligible for surgery in order to control their hypermenorrhoea. Considerable side effects did not occur over the course of 3 months with dosages of 5 as well as 10 mg of UPA. A reduction of the uterine bleeding was already observed after 7 days, along with a volume reduction by 40% in the uterine myomas within 3 months, which also appeared to be sustained for 6 months after the end of treatment. Esmya®, a tablet with 5 mg ulipristal acetate, was approved by the EMA for the preoperative treatment of symptomatic leiomyoma in spring 2012.br The PEARL-III study examined the control of bleeding, volume reduction in myoma, quality of life and pain in symptomatic myoma patients after four 3-month courses of UPA treatment cycles (10 mg/day. Each 3-month treatment cycle was followed by 10 days of double-blind treatment with either 10 mg norethisterone acetate (NETA or Placebo and a treatment-free period of two menstrual cycles. The follow-up period was three months after the end of the fourth treatment course. The NETA therapy had no effect on the primary and main secondary study parameters. During the study, a control of the bleeding could be achieved in 94% of the patients, and 90% were seen to develop amenorrhea. The total volume reduction (median of the three largest myomas after 4 treatment cycles was about 72% and 82% of the

    Objective:To study the role of diabetes, hypertension and obesity in etiology of endometrial polyps. Methods: A total of 250 patients with endometrial polyp and 256 patients normal endometrial cavity were included, who applied to our outpatient clinic. We recorded the age, fertility state, body mass index, number of polyps, hypertension and diabetes status of the patients by using SPSS Windows 16.0. All patients in polyp group were verified by post-operative pathology report. Results:No significant difference was found in patients with diabetes and obesity, but hypertension was a significant factor in patients who had endometrial polyp comparing to total patient population (n=526). Conclusions:This finding may alert the physician to consider the endometrial cavity in hypertensive patients who applied with abnormal uterine bleeding.

    Full Text Available Aim: To investigate endocrinologic and endometrial factors in cases of recurrent abortions. Material and Method: In cases of recurrent abortions, clinical and ultrasonographic features, genetic, anatomic and immunologic factors, hormonal profiles and endometrial samplings were assessed. Chromosomal abnormalities and uterine anomalies were excluded. Results: In 8 (14% of 57 cases with recurrent abortions, there were low progesterone levels. In 1 (1.75% case there was a high androgen level. In 2 (3.5% cases there was hyperprolactinemia and in another 2 (3.5% cases there were high insulin levels. In 4 (7% cases two scores of OGTT were high. In 51 cases where endometrial sampling was performed, only one (1.75% case had delayed endometrial development. Discussion: We conclude that recurrent abortions have a complex etiology related to endocrinologic and endometrial factors.

For this, Holstein Frisian cows at 42–60 days postpartum were classified as heal...

  16. Asymptomatic uterine fibroids.

    Divakar, Hema

    2008-08-01

    It is estimated that at least 50% of fibroids are asymptomatic, but this figure is likely to be an underestimate as it is based on women in whom fibroids are found incidentally during another procedure (e.g. cervical screening), and there is little, if any, data from population studies on the true incidence of fibroids. If a prevalence of 50% by 50 years of age is accepted, a large number of women have asymptomatic fibroids. Working on the cliché, 'if it ain't broken, don't fix it', it may seem surprising that there should be a chapter dedicated to the issue of asymptomatic fibroids, since the simplistic approach might be to leave the asymptomatic fibroids well alone. However, asymptomatic fibroids may become symptomatic in the future, so it may be wiser to treat fibroids before they grow to a size when they become symptomatic, or treatment becomes more challenging, especially in young women who may desire fertility at a later stage, and in view of the fact that many women are starting their families in their mid-thirties when they have a 30% chance of having a fibroid(s). Despite their common occurrence, fibroids are still poorly understood. It is not known why they form in the first place, what determines their number and ultimate size, the best treatment approaches, or the factors that determine which women develop symptoms. Even when women present with disorders such as infertility, pelvic pain and abnormal bleeding, it is not always possible to be certain that a given myoma is not simply an innocent bystander rather than the cause of the symptom. This chapter addresses the challenging issue of what to do when fibroids are diagnosed incidentally. Firstly, there is the need to ascertain that the pelvic mass palpated is indeed a fibroid, and not an early, more sinister tumour, especially if conservative management is adopted. In addition, there is the issue of size, position and potential for becoming symptomatic at a later date. With the availability of uterine

  18. Adenovirus mediated homozygous endometrial epithelial Pten deletion results in aggressive endometrial carcinoma

    Pten is the most frequently mutated gene in uterine endometriod carcinoma (UEC) and its precursor complex atypical hyperplasia (CAH). Because the mutation frequency is similar in CAH and UEC, Pten mutations are thought to occur relatively early in endometrial tumorigenesis. Previous work from our laboratory using the Pten+/- mouse model has demonstrated somatic inactivation of the wild type allele of Pten in both CAH and UEC. In the present study, we injected adenoviruses expressing Cre into the uterine lumen of adult Pten floxed mice in an attempt to somatically delete both alleles of Pten specifically in the endometrium. Our results demonstrate that biallelic inactivation of Pten results in an increased incidence of carcinoma as compared to the Pten+/- mouse model. In addition, the carcinomas were more aggressive with extension beyond the uterus into adjacent tissues and were associated with decreased expression of nuclear ERα as compared to associated CAH. Primary cultures of epithelial and stromal cells were prepared from uteri of Pten floxed mice and Pten was deleted in vitro using Cre expressing adenovirus. Pten deletion was evident in both the epithelial and stromal cells and the treatment of the primary cultures with estrogen had different effects on Akt activation as well as Cyclin D3 expression in the two purified components. This study demonstrates that somatic biallelic inactivation of Pten in endometrial epithelium in vivo results in an increased incidence and aggressiveness of endometrial carcinoma compared to mice carrying a germline deletion of one allele and provides an important in vivo and in vitro model system for understanding the genetic underpinnings of endometrial carcinoma.

There were statistically signiifcant differences between the RI of benign lesions and patients with endometrial carcinoma (P<0.05). In contrast with the pathologically-conifrmed results, the accurate diagnostic rate of TVCDS in endometrial polyps, submucous myoma, endometrial hyperplasia and endometrial carcinoma were 91.3%, 95.1%, 96.9% and 92.0% respectively.ConclusionTVCDS demonstrated itself as a diagnostic method with the high detection rate of endometrial lesions and minimal damage to patients’ uteruses, which deserved wider clinical promotion.

  1. Endometrial carcinoma in elderly women.

    1995-08-01

    Endometrial carcinoma remains the most common invasive gynecologic malignancy. Increased longevity is associated with an increased incidence of endometrial carcinoma (EC) in elderly women. While recent studies have looked at aging and its relation to ovarian, breast, and cervical cancer, few have focused on EC in the growing elderly population. This study analyzed 35 histologic specimens of EC in women 75-92 years of age. Findings revealed that only 23% of the tumors were Stage I, G1. The majority (77%) were deeply invasive or of advanced stage (IC-IV). These were G2, G3, or "virulent" types of nonendometrioid EC (undifferentiated, clear cell, uterine serous papillary, and squamous cell carcinoma). Fifty-seven percent of tumors were endometrioid, of which 9% were mixed, including a rare case of nongestational choriocarcinoma. The nonendometrioid tumors, compared to the endometrioid types, were more often high-stage tumors with vascular invasion. They were also more often associated with atrophic (vs hyperplastic) uninvolved endometrium. Clinical risk factors (nulliparity, obesity, estrogen replacement therapy) were assessed and correlated with the histologic findings. It was shown that tumors in the elderly were less likely to be estrogen-related. It was concluded that EC in this age group is more aggressive, histologically less differentiated, and often nonendometrioid compared with EC in the general population. The increased virulence of EC in the elderly may be related to the tumor's independence from hormonal factors, to the poorly understood but well-known diminished immunologic defense against cancer in general in elderly patients, and/or to the belated diagnosis of the disease in this population.

  3. Therapeutic management of uterine fibroid tumors.

    Puchar, Anne; Feyeux, Cécile; Luton, Dominique; Koskas, Martin

    2016-08-01

    Fibroids, which are benign smooth-muscle tumors of clonal origin, are the most common gynecologic tumors occurring in about 20 to 25 % of women over 30 years of age. The most frequent symptoms are pelvic pain and heavy menstrual bleeding resulting in anemia. The role of fibroids in infertility remains debated but probably mostly related to submucosal location due to implantation impairment. Although most women are asymptomatic (80%), fibroids can have a considerable impact on quality of life. Considering this impact and the cost associated with their management, treatment of fibroids is a public health concern. Treatment options for symptomatic fibroids include medical, surgical and alternatives techniques. Medical management is mainly based on the use of progestogens, antifibrinolytics agents, non-steroidal anti-inflammatory drugs, Gonadotropin-releasing hormone analogs selective progesterone receptor modulators. Surgical management includes myomectomy (hysteroscopic, laparoscopic, minilaparoscopic or laparotomic) and hysterectomy. The choice of surgery depends on several factors: the number, topography and size of myomas, the age of the patient and her desire for fertility, treatment history and her desire to keep the uterus. Alternatives techniques to surgery are mainly based on the uterine artery embolization. The aim of this article is to provide evidence based recommendations for the management of uterine fibroids.

  4. Clinical evaluation of high-intensity focused ultrasound in treating uterus myomas

    Objective: To explore the safety and efficacy of high-intensity focused ultrasound (HIFU) for the treatment of uterus myomas. Methods: HIFU was performed in 47 patients with symptomatic hysteromyoma, who had a childbearing history and were 26-59 years old. Postoperative follow-up was carried out. Clinical symptoms and the tumor's size were observed before and after the HIFU treatment. The results were compared with each other. Results: After HIFU treatment, the symptoms such as dysmenorrhea and hypermenorrhea were markedly improved. Some patients developed hematuria or lower limb pain, which was relieved after symptomatic management. The average volume of myoma before the treatment was (47.6 ± 24.1) cm3 and it was reduced to (17.7 ± 13.1) cm3 at 6 months after the treatment, the difference was statistically significant (P < 0.05). Conclusion: HIFU is a safe and effective treatment for uterus myomas. (authors)

    Tamoxifen has been a very effective treatment for breast cancer for several decades, however, at the same time increases the risk of endometrial cancer, especially after prolonged exposure. In addition, tamoxifen has been associated with a higher proportion of unfavorable uterine tumor subtypes (car

    The aim of this study was to determine the frequency of abnormal cervical cytology in preoperative cervical cytology of patients diagnosed with uterine papillary serous carcinoma (UPSC) and endometrioid endometrial carcinoma (EEC). In addition, associations between abnormal cervical cytology and clinicopathologic factors were evaluated. In this multicentre study, EEC patients diagnosed at two hospitals from 1999 to 2009 and UPSC patients diagnosed at five hospitals from 1992 to 2009, were included. Revision of the histologic slides was performed systematically and independently by 3 gynecopathologists. Cervical cytology within six months before histopathologic diagnosis of endometrial carcinoma was available for 267 EEC and 80 UPSC patients. Cervical cytology with atypical, malignant, or normal endometrial cells in postmenopausal women was considered as abnormal cytology, specific for endometrial pathology. Abnormal cervical cytology was found in 87.5% of UPSC patients, compared with 37.8% in EEC patients. In UPSC, abnormal cytology was associated with extrauterine spread of disease (P=0.043). In EEC, abnormal cytology was associated with cervical involvement (P=0.034). In both EEC and UPSC patients, abnormal cervical cytology was not associated with survival. In conclusion, abnormal cervical cytology was more frequently found in UPSC patients. It was associated with extrauterine disease in UPSC patients, and with cervical involvement in EEC patients. More prospective research should be performed to assess the true clinical value of preoperative cervical cytology in endometrial cancer patients. PMID:23722512

    To elucidate the roles of human herpesvirus (HHV)-6 primary unexplained infertile women, a prospective randomized study was conducted on a cohort of primary unexplained infertile women and a cohort of control women, with at least one successful pregnancy. HHV-6 DNA was analyzed and the percentage and immune-phenotype of resident endometrial Natural Killer (NK) cells, as the first line of defense towards viral infections, was evaluated in endometrial biopsies. Cytokine levels in uterine flushing samples were analyzed. HHV-6A DNA was found in 43% of endometrial biopsies from primary unexplained infertile women, but not in control women. On the contrary, HHV-6B DNA was absent in endometrial biopsies, but present in PBMCs of both cohorts. Endometrial NK cells presented a different distribution in infertile women with HHV6-A infection compared with infertile women without HHV6-A infection. Notably, we observed a lower percentage of endometrial specific CD56brightCD16- NK cells. We observed an enhanced HHV-6A-specific endometrial NK cell response in HHV-6A positive infertile women, with a marked increase in the number of endometrial NK cells activating towards HHV-6A infected cells. The analysis of uterine flushing samples showed an increase in IL-10 levels and a decrease of IFN-gamma concentrations in infertile women with HHV6-A infection. Our study indicates, for the first time, that HHV-6A infection might be an important factor in female unexplained infertility development, with a possible role in modifying endometrial NK cells immune profile and ability to sustain a successful pregnancy.

  10. Uterine horn aplasia with complications in two mixed-breed bitches : case report

    M.L. Schulman

    1997-07-01

    Full Text Available Unilateral segmental uterine horn aplasia was found in 2 mixed-breed bitches. The 1st bitch was presented with clinical signs of acute abdominal pain, and pyometra was suspected. Pyometra was confirmed surgically with rupture of a blind-ending cranial portion of the anomalous right uterine horn, which had resulted in peritonitis. The 2nd bitch was presented for routine ovariohysterectomy. The right uterine horn was affected by segmental aplasia, with mucometra of the cranial portion of the affected horn. Histopathology demonstrated both uteri to have diffuse cystic endometrial hyperplasia. It is postulated that cystic endometrial hyperplasia, together with the congenital anomaly, resulted in pyometra in one case and in mucometra in the other case. This is believed to be the 1st report of uterine horn aplasia in the bitch in association with clinical signs and lesions other than infertility.

    2016-02-01

    Endometrial cancer (EC) is the commonest gynaecological cancer in the Western World with an alarmingly increasing incidence related to longevity and obesity. Ovarian hormones regulate normal human endometrial cell proliferation, regeneration and function therefore are implicated in endometrial carcinogenesis directly or via influencing other hormones and metabolic pathways. Although the role of unopposed oestrogen in the pathogenesis of EC has received considerable attention, the emerging role of other hormones in this process, such as androgens and gonadotropin-releasing hormones (GnRH) is less well recognised. This review aims to consolidate the current knowledge of the involvement of the three main endogenous ovarian hormones (oestrogens, progesterone and androgens) as well as the other hormones in endometrial carcinogenesis, to identify important avenues for future research.

    Uterine papillary serous carcinoma (UPSC) is an aggressive variant of endometrial cancer. Owing to its rarity, most clinicians are unfamiliar with the clinical aspects and management of UPSC. Furthermore, little prospective evidence exists regarding how best to treat this subset of patients. In anticipation of prospective clinical trials, this article summarizes the latest results of various clinical management options in the different substages of UPSC, with a special focus on the effects of cytoreductive surgery, comprehensive surgical staging and different adjuvant treatment options in relation to recurrence rate and survival outcome.

  16. Interdisciplinary stratification of patients with myoma-related symptoms

    With the establishment of uterine artery embolization (UAE), the individualization of treatment of the symptomatic myomatous uterus showed a general progression. The concrete therapy decision is made in an interactive process between doctor and patient. A series of factors influence the choice of a suitable, operative or non-operative, therapeutic procedure. In the weighting of therapeutic options between surgery or UAE, in addition to current results of studies which compare both techniques,recommendations made by expert committees and guidelines are helpful for a competent counseling of patients and additionally supportive in decision processes such as interdisciplinary stratification.

  17. Uterine fibroids: clinical manifestations and contemporary management.

    Doherty, Leo; Mutlu, Levent; Sinclair, Donna; Taylor, Hugh

    2014-09-01

    Uterine fibroids (leiomyomata) are extremely common lesions that are associated with detrimental effects including infertility and abnormal uterine bleeding. Fibroids cause molecular changes at the level of endometrium. Abnormal regulation of growth factors and cytokines in fibroid cells may contribute to negative endometrial effects. Understanding of fibroid biology has greatly increased over the last decade. Although the current armamentarium of Food and Drug Administration-approved medical therapies is limited, there are medications approved for use in heavy menstrual bleeding that can be used for the medical management of fibroids. Emergence of the role of growth factors in pathophysiology of fibroids has led researchers to develop novel therapeutics. Despite advances in medical therapies, surgical management remains a mainstay of fibroid treatment. Destruction of fibroids by interventional radiological procedures provides other effective treatments. Further experimental studies and clinical trials are required to determine which therapies will provide the greatest benefits to patients with fibroids. PMID:24819877

  18. Isolated Uterine Metastasis of Invasive Ductal Carcinoma

    2013-01-01

    Full Text Available Introduction. Most common metastasis sites of breast cancer are the lungs, bones, liver, and brain, whereas uterine involvement by metastatic breast disease is rare. Metastatic carcinoma of the uterus usually originates from other genital sites, most commonly being from the ovaries. Invasive lobular carcinoma spreads to gynecologic organs more frequently than invasive ductal carcinoma. Case Report. A 57-year-old postmenopausal woman was diagnosed with breast carcinoma 2 years ago and modified radical mastectomy was performed. Pathological examination of tumor revealed invasive ductal carcinoma, stage IIIc. She presented with abdominal pain and distension. Diagnostic workup and gynecologic examination revealed lesions that caused diffuse thickening of the uterus wall. Endometrial sampling was performed for confirmation of the diagnosis. She underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. Breast carcinoma metastases in endometrium and myometrium were confirmed histopathologically and immunohistochemically. Conclusion. We herein report the first case of isolated uterine patient who had invasive ductal carcinoma of breast.

  19. T2-weighted sequences in the MR study of endometrial carcinoma and their histological correlation

    The degree of myometrial involvement is one of the factors that most markedly affect the prognosis and mode of treatment of endometrial carcinoma in its early stages. Our objective is to assess the value of MR in detecting the degree of myometrial invasion in patients with low-grade endometrial carcinoma and correlated some features of the MR images with the histological findings. We performed a prospective study in 25 postmenopausal patients diagnosed as having endometrial carcinoma on the basis of Pap smear. Using a 0.5 Tesla MR, T1-weighted, T2-weigheted and PD axial, coronal and sagittal prohections were done in the uterus. Shortly afterwards, radical hysterectomy and pelvic lymphadenectomy were carried out and the MR findings were compared with the results of the histological study of the resected tissue. The following parameters were recorded at MR for the evaluation of the endometrial carcinoma: size of the uterus, endometrial thickness, presence or absence of a mas, cervical involvement, lymph node involvement and degree of myometrial invasion (more or less than 50% of the tickness): in the latter case, the junction was assessed when visible and the tumor-myometrium interface when it was not. The overall validity of MR in the detection of deep invasion was 80%, with a sensitivity of 80% and a specificity of 80%. The major errors invlved four cases of overstimation of the depth of the invasion. In two of them, the surgical specimens presented polypoid masses that distended the uterus, stretching out the myometrium, in another, the histological study disclosed a myoma accompanied by sites of adenomyomatosis; and the fourth case presented senile myometrial atrophy. MR is useful in the preoperative staging of endometrial carcinoma as it is capable of predicting the degree of myometrial invasion, upon which the lymphatic dissemination depends directly. This information is the basis for chroosing a more or less aggressive surgical approach and for deciding on the

    The appropriate surgical technique to treat patients with uterine fibroids is still a matter of debate as is the potential risk of incorrect treatment if histological examination detects a uterine sarcoma instead of uterine fibroids. The published epidemiology for uterine sarcoma is set against the incidence of accidental findings during surgery for uterine fibroids. International comments on this topic are discussed and are incorporated into the assessment by the German Society for Gynecology and Obstetrics (DGGG). The ICD-O-3 version of 2003 was used for the anatomical and topographical coding of uterine sarcomas, and the “Operations- und Prozedurenschlüssel” (OPS) 2014, the German standard for process codes and interventions, was used to determine surgical extirpation methods. Categorical qualifiers were defined to analyze the data provided by the Robert Koch Institute (RKI), the German Federal Bureau of Statistics (DESTATIS; Hospital and Causes of Death Statistics), the population-based Cancer Register of Bavaria. A systematic search was done of the MEDLINE database and the Cochrane collaboration, covering the period from 1966 until November 2014. The incidence of uterine sarcoma and uterine fibroids in uterine surgery was compared to the literature and with the different registries. The incidence of uterine sarcoma in 2010, standardized for age, was 1.53 for Bavaria, or 1.30 for every 100 000 women, respectively, averaged for the years 2002–2011, and 1.30 for every 100 000 women in Germany. The mean incidence collated from various surveys was 2.02 for every 100 000 women (0.35–7.02; standard deviation 2.01). The numbers of inpatient surgical procedures such as myoma enucleation, morcellation, hysterectomy or cervical stump removal to treat the indication “uterine myoma” have steadily declined in Germany across all age groups (an absolute decrease of 17 % in 2012 compared to 2007). There has been a shift in the preferred method of surgical

    HSoG for anormal, sugerimos confirmar o exame pela histeroscopia diagnóstica. Pelo fato de a HSoG apresentar boa especificidade e bom valor preditivo negativo, poderíamos sugerir que diante de HSoG normal não há necessidade de indicação de se avaliar a cavidade uterina pela histeroscopia diagnóstica antes de realizar a fertilização in vitro. Concluímos que a histero-sonografia é bom método para rastreamento de lesões polipóides da cavidade uterina que possam responder pela falha de implantação nas técnicas de fertilização in vitro.PURPOSE: to analyze the accuracy of sonohysterography for the evaluation of the uterine cavity in patients with an implantation failure, at the first attempt of an in vitro fertilization cycle. METHODS: in a prospective double blind study, the authors analyzed patients previously submitted to at least one embryo transfer, who presented implantation failures. The patients were submitted to a sonohysterographic examination followed by a diagnostic hysteroscopic examination, carried out by different professionals each of whom was not aware of the results of the other. The results were recorded and only interpreted after the end of the trial. Sonohysterography was performed by the introduction of a urethral catheter 8 into the uterine cervix followed by infusion of physiological saline. The anechoic interface shown by the physiological saline can reveal abnormalities, like uterine polyps or submucosal myomas. Hysteroscopy was performed with a Karl Storz equipment, 4 mm 30º rigid telescope, and infusion of physiological saline for uterine cavity distention. RESULTS: twenty-eight of the 33 originally selected patients for this study were analyzed. Sonohysterography detected abnormalities in 8 patients, five with endometrial polyps (62.5%, two with endocervical polyps (25.0%, and one with submucosal myoma (12.5%. Hysteroscopy (gold standard detected abnormalities in 7 patients, two with endometrial polyps (28.6%, two with

  7. Relaxation time of magnetic resonance imaging on the uterine diseases

    Magnetic Resonance Imaging (MRI) has been developed by use of the theory based on MR-phenomena. In the present paper, diagnostic analysis was performed on the various disorders of the uterus by use of MRI. 30 selected patients were subjected, they are one case of diagnosed hydatidiform mole, 11 cases of myoma uteri, 1 case of adenomyosis, 3 cases of ca. corporis uteri, and 14 cases of ca. colli uteri. MRI facility used was Magnetom M5, Siemens Co. with 0.5 Tesla superconducting magnet. As for tissue parameter of these lesions, both T1 and T2 values were measured. The features of hydatidiform mole showed dense granular pattern according to small cystic vesicles. Myoma nodule without degeneration showed low intensity, clear image of nodule and the shortest T1 and T2 values (T1/T2 values:635.2/43.9 msec). In case of their degeneration, increased intensity and larger T1 and T2 values (T1/T2 values:1219.3/112.7 msec) were shown. Adenomyosis showed widely, diffuse low intensity area within high intensity spots (T1/T2 values:561.7/51.6 msec). Both malignant lesions of uterine body and cervix showed as high intensity on the T2 weighed SE image and similar T1 and T2 value (T1/T2 values:774.4/72.8 and 789.4/74.4 msec) respectively. But their values were lower than normal tissue. It is suggested that MRI has good advantage for differential diagnosis of the uterine diseases. (author)

  9. NMU signaling promotes endometrial cancer cell progression by modulating adhesion signaling.

    Lin, Ting-Yu; Wu, Fang-Ju; Chang, Chia-Lin; Li, Zhongyou; Luo, Ching-Wei

    2016-03-01

    Neuromedin U (NMU) was originally named based on its strong uterine contractile activity, but little is known regarding its signaling/functions in utero. We identified that NMU and one of its receptors, NMUR2, are not only present in normal uterine endometrium but also co-expressed in endometrial cancer tissues, where the NMU level is correlated with the malignant grades and survival of patients. Cell-based assays further confirmed that NMU signaling can promote cell motility and proliferation of endometrial cancer cells derived from grade II tumors. Activation of NMU pathway in these endometrial cancer cells is required in order to sustain expression of various adhesion molecules, such as CD44 and integrin alpha1, as well as production of their corresponding extracellular matrix ligands, hyaluronan and collagen IV; it also increased the activity of SRC and its downstream proteins RHOA and RAC1. Thus, it is concluded that NMU pathway positively controls the adhesion signaling-SRC-Rho GTPase axis in the tested endometrial cancer cells and that changes in cell motility and proliferation can occur when there is manipulation of NMU signaling in these cells either in vitro or in vivo. Intriguingly, this novel mechanism also explains how NMU signaling promotes the EGFR-driven and TGFβ receptor-driven mesenchymal transitions. Through the above axis, NMU signaling not only can promote malignancy of the tested endometrial cancer cells directly, but also helps these cells to become more sensitive to niche growth factors in their microenvironment.

  10. Long-term survival in uterine clear cell carcinoma and uterine papillary serous carcinoma.

    Lindahl, Bengt; Persson, Jan; Ranstam, Jonas; Willén, Roger

    2010-09-01

    Uterine clear cell carcinoma (UCC) and uterine papillary serous carcinoma (UPSC) are rare entities that differ in clinical behavior from endometrial adenocarcinoma. Compared with endometrioid adenocarcinoma, they more often metastasize early and more commonly in the upper abdomen including the omentum. Treatment programs of UCC and UPSC at different stages vary and range from no adjuvant therapy in stage Ia to a wide variety of chemotherapies and radiotherapies in more advanced stages. This study presents the outcome of 109 patients with UCC or UPSC treated according to essentially the same treatment program from May 1993 to December 2004. Most patients were treated with a simple hysterectomy with no further adjuvant treatment. In stage Ia, 2/46 patients died of their disease and amongst all the stages, 30/109 patients died of their disease. These survival outcomes are comparable to or better than those presented previously. PMID:20944161

  11. Apparent diffusion coefficient of diffusion weighted MRI in endometrial carcinoma—Relationship with local invasiveness

    Objective: To evaluate the relationship between apparent diffusion coefficient (ADC) value and the local invasiveness of endometrial carcinoma. Methods and materials: The MR imaging of seventy-three patients with endometrial carcinoma proved by post-operative pathology and sixty-four patients with healthy uteri were retrospectively reviewed. All MR examinations included axial T2WI and T1WI, sagittal T2WI and diffusion-weighted sequences (b = 0 and b = 1000 s/mm2). Tumor size, mean ADC value (ADCm) and quartile ADC (ADCq) were acquired on post-processing workstation using voxel-analysis software. Differences between the ADC values among three layers of normal uterine body and endometrial carcinomas were compared by ANOVA test. Groups were divided according to pathologic type, histologic grade, depth of myometrial infiltration, presence of cervical invasion and lymphovascular space invasion, and lymph node metastasis. Tumor size and ADC values were compared and analyzed. Results: ADC values were different in three zones of uterine body (P −3 mm2/s] and highest in outer myometrium [(1.496 ± 0.196) × 10−3 mm2/s]. Mean ADC value of endometrial carcinomas [(1.011 ± 0.121) × 10−3 mm2/s] was lower than the normal uterine body. Quartile ADC and tumor size were greater in groups with more invasive pathologic factors (P < 0.05). Deep myometrial infiltration, cervical invasion, lymphovascular space invasion and lymph node metastasis were more common as quartile ADC values and tumor sizes increased. Conclusion: Mean ADC value was lower in endometrial carcinoma was lower than the normal uterus. Quartile ADC, representing the intra-tumor heterogeneity of water movement, had a profound relationship with invasiveness of endometrial carcinomas, while mean ADC value did not. ADC values may serve as a quantitative indicator to complement routine sequences.

  12. Uterine Artery Embolization Versus Laparoscopic Uterine Artery Occlusion: The Outcomes of a Prospective, Nonrandomized Clinical Trial

    Purpose: To compare outcomes of two different types of occlusive therapy of uterine fibroids. Methods: Women with fibroid(s) unsuitable for laparoscopic myomectomy (LM) were treated with uterine artery embolization (UAE) or laparoscopic uterine artery occlusion (LUAO). Results: Before the procedure, patients treated with UAE (n = 100) had a dominant fibroid greater in size (68 vs. 48 mm) and a mean age lower (33.1 vs. 34.9 years) than surgically treated patients (n = 100). After 6 months, mean shrinkage of fibroid volume was 53 % after UAE and 39 % after LUAO (p = 0.063); 82 % of women after UAE, but only 23 % after LUAO, had complete myoma infarction (p = 0.001). Women treated with UAE had more complications (31 vs. 11 cases, p = 0.006) and greater incidence of hysteroscopically verified intrauterine necrosis (31 vs. 3 %, p = 0.001). Both groups were comparable in markers of ovarian functions and number of nonelective reinterventions. The groups did not differ in pregnancy (69 % after UAE vs. 67 % after LUAO), delivery (50 vs. 46 %), or abortion (34 vs. 33 %) rates. The mean birth weight of neonates was greater (3270 vs. 2768 g, p = 0.013) and the incidence of intrauterine growth restriction lower (13 vs. 38 %, p = 0.046) in post-UAE patients. Conclusion: Both methods are effective in the treatment of women with future reproductive plans and fibroids not suitable for LM. UAE is more effective in causing complete ischemia of fibroids, but it is associated with greater risk of intrauterine necrosis. Both methods have low rate of serious complications (except for a high abortion rate).

    Purpose: To compare outcomes of two different types of occlusive therapy of uterine fibroids. Methods: Women with fibroid(s) unsuitable for laparoscopic myomectomy (LM) were treated with uterine artery embolization (UAE) or laparoscopic uterine artery occlusion (LUAO). Results: Before the procedure, patients treated with UAE (n = 100) had a dominant fibroid greater in size (68 vs. 48 mm) and a mean age lower (33.1 vs. 34.9 years) than surgically treated patients (n = 100).

    Full Text Available Os tumores mistos de células musculares lisas e do estroma endometrial uterino, caracterizados pela presença de componentes de ambas as linhagens, coexistindo em proporções quase equivalentes, são neoplasmas raros. Possuem potencial biológico incerto e se comportam de acordo com o componente estromal. A imuno-histoquímica é uma grande aliada no diagnóstico microscópico, pois a clínica e os exames de imagem não ajudam a diferenciá-los de outras doenças uterinas. Descrevemos o caso de uma paciente cuja hipótese diagnóstica era de leiomioma uterino e que, após cirurgia, foi diagnosticada pelo estudo anatomopatológico como tumor misto de células musculares lisas e do estroma endometrial uterino.Mixed tumors of uterine smooth muscle and endometrial stromal cells, which are characterized by the presence of components from both cell lineages with similar proportions, are rare neoplasms. Their biological potential is uncertain, and they behave according to the stromal component. Immunohistochemistry is an important ally in microscopic diagnosis, because symptoms and imaging exams do not help in the differentiation from other uterine diseases. We describe a case of a patient who had been previously diagnosed with uterine leiomyoma, and after surgery, the anatomopathological study revealed a mixed tumor of uterine smooth muscle and endometrial stromal cells.

  15. Uterine papillary serous carcinoma:Its clinical and fundamental study

    2000-01-01

    Uterine papillary serous carcinoma (UPSC) was established as a distinct type of endometrial carcinoma by Lauchlan in 1981 and Hendrickson et al in 1982, and accounted for 1% ~ 10% of endometrial cancers. Theoccurencer of papillary patterns of endometrial adenocarcincma had been reportedly recognized since 1900, while until the late 1970s several authors have had described a variant of papillary endometrial cancer. UPSC is a morphologically unique variant of endometrial carcinoma that is pathologically defined by the presence of high nuclear grade, distinct papillary architechtural changes, psammoma bodies, and extensive lymph- vascular space invasion. CA125 is often mentioned a usefultumor marker either for diagnosis before starting treatment or in monitoring recurrence. The ptimal treatment of UPSC is controversial and appears to be dependent upon the stage of the disease. Primary surgery comprised of TAH/BSO and complete staging is the mainstay of treatment. The patients with recurrent UPSC in many studies were treated with various combinations of surgery, radiation therapy, and chemotherapy. The molecular basis for the general poor response of UPSC to adjuvant chemotherapy and radiotherapy is not well understood. UPSC tumors are more often aneuploid and contain overexpressed mutant p53 protein as compared to encdometrioid adenocarcinoma. Unlike patients with adenocarcinoma of the endomeutrium, women with UPSC were less likely to be obese, hypertensive, or diabetic.

  16. Diagnostic application of KRAS mutation testing in uterine microglandular proliferations.

    Hong, Wei; Abi-Raad, Rita; Alomari, Ahmed K; Hui, Pei; Buza, Natalia

    2015-07-01

    Microglandular proliferations often pose a diagnostic challenge in small endocervical and endometrial biopsies. Microglandular hyperplasia (MGH) is one of the most common pseudoneoplastic glandular proliferations of uterine cervix, which can closely mimic endometrial adenocarcinomas (EAC) with a microglandular pattern (microglandular EAC). Although MGH is typically characterized by relatively uniform nuclei and rare to absent mitoses, atypical forms with architectural and/or cytologic deviation from the usual morphology have been previously described. Recently, a series of MGH with high mitotic activity has also been documented. Although careful morphological assessment and immunohistochemical workup can resolve the diagnostic dilemma in some cases, additional differential diagnostic tools are needed to separate both the common and atypical variants of MGH from EAC with microglandular pattern. Frequent KRAS mutation has been previously reported in endometrial complex mucinous lesions and endometrial mucinous carcinomas. However, the diagnostic utility of KRAS mutation analysis has not yet been explored in the context of cervical and endometrial microglandular lesions. Twelve mitotically active MGH cases and 15 cases of EAC with microglandular growth pattern were selected for the study. KRAS mutation analysis was performed in all cases by highly sensitive single-strand conformation polymorphism analysis. Clinical history and follow-up data were retrieved from electronic medical records. KRAS mutation was absent in all MGH cases, whereas 9 (60%) of 15 microglandular EAC cases tested positive for KRAS mutation. Our data indicate that KRAS mutation analysis may offer additional discriminatory power in separating benign MGH from EAC with microglandular pattern. PMID:25997988

  17. Surgical and medical management of a uterine spindle cell tumor in an African hedgehog (Atelerix albiventris).

    Done, Lisa B; Deem, Sharon L; Fiorello, Christine V

    2007-12-01

    A 5-yr-old female African hedgehog (Ateleris albiventris) presented with hematuria. Vulvar culture results revealed a 4+ growth of Enterococcus sp. and gamma-Streptococcus sp. susceptible to trimethoprim sulfa and enrofloxacin. Ultrasound evaluation of the abdomen revealed an unidentifiable tubular structure in the region of the reproductive tract. An exploratory laparotomy and ovariohysterectomy were performed. Pathologic studies of the uterus showed a uterine spindle cell tumor, uterine endometrial polyp, uterine adenomyosis, and a possible acute infarct resulting in uterine wall necrosis. Hematuria did not reoccur, and the hedgehog lived for another 19 mo until she died from an oral squamous cell carcinoma. To date, this is the first report of a uterine spindle cell tumor in an African hedgehog. PMID:18229871

  18. Estrogen disruption of neonatal ovine uterine development: effects on gene expression assessed by suppression subtraction hybridization.

    Hayashi, Kanako; Spencer, Thomas E

    2005-10-01

    Inappropriate exposure of neonatal sheep to estrogen during critical developmental periods inhibits or retards endometrial gland morphogenesis and reduces uterine growth. Studies were conducted to identify mechanisms mediating estrogen disruption of neonatal ovine uterine development by analysis of candidate growth factor systems and using suppression subtraction hybridization (SSH). In study 1, sheep were exposed either to corn oil as a control or to estradiol valerate (EV) from birth to Postnatal Day (PND) 14, which ablated endometrial gland development. Estradiol valerate decreased uterine FGF7 (fibroblast growth factor 7) and MET (hepatocyte growth factor receptor) expression and increased INHBA (inhibin betaA). The SSH identified a number of genes responsive to EV, which included GSTM3 (glutathione S-transferase), IDH1 (cytosolic NADP-isocitrate dehydrogenase), PECI (peroxisomal D(3),D(2)-enoyl-coenzyme A isomerase), OAS1 (2',5'-oligoadenylate 40/46-kDa synthetase), IGFBP3 (insulin-like growth factor-binding protein-3), TEGT (testis-enhanced gene transcript), CXCL10 (interferon-gamma-inducible protein 10), and IGLV (immunoglobulin V). These mRNAs were expressed predominantly in the endometrial epithelia (GSTM3, IDH1, PEC1, OAS1, and TEGT), stroma (IGFBP3), or immune cells (CXCL10 and IGLV). In study 2, effects of estrogen exposure on uterine gene expression were determined during three different critical developmental periods (PNDs 0-14, 14- 28, and 42-56). Estrogen exposure decreased expression of the SSH-identified genes, particularly those from PNDs 0-14. These studies suggest that estrogen disruption of postnatal uterine development involves period-specific effects on expression of genes predominantly in the endometrial epithelium. The SSH-identified, estrogen-disrupted genes represent new candidate regulators of postnatal endometrial adenogenesis. PMID:15972882

  1. Accuracy of doppler ultrasound in diagnosis of endometrial carcinoma

    Objective: To determine the accuracy of Doppler ultrasound in the diagnosis of endometrial carcinoma in patients presenting with post-menopausal bleeding while taking histopathological findings as the gold standard. Methods: The cross-sectional study was done at the Department of Radiology, Bahawal Victoria Hospital, Bahawalpur, from April 1 to September 30, 2009, and comprised 128 patients above 50 years of age having history of post-menopausal bleeding and who were referred to the department. Name, age and hospital registration number were recorded on a proforma. Doppler ultrasound was performed and endometrial thickness and uterine artery resistive index were recorded on transabdominal ultrasonography. Patients with endometrial thickness of more than 5mm and uterine artery resistive index of less than 0.7 were considered to be having endometrial carcinoma. Histopathology findings were also recorded using the hospital registration number of the patient. The findings of Doppler ultrasound scan were validated with the findings of histopathology. Results: Of the 128 patients, 48 (37.5%) were between the ages of 51 and 55 years; 46 (35.93%) were in the 56-60 age group; and 34 (26.57%) were over 65 years. On the basis of Doppler ultrasound findings, 106 (82.8%) patients were diagnosed as having endometrial carcinoma, while 22 (17.19%) were declared negative. Ultrasonography results were compared with histopathology findings. The percentages of true positive, true negative, false positive and false negative were calculated. There were 103 (80.47%) true positive; 12 (9.37%) false positive; 10 (7.81%) true negative; and 3 (2.35%) false negative. Specificity, sensitivity, positive predictive value and negative predictive value were found to be 97.16%, 76%, 89.56% and 76.92% respectively. Conclusion: The use of Doppler ultrasonography in non-invasive diagnosis of endometrial carcinoma in patients presenting with post-menopausal bleeding was quite useful with good

  3. Oxytocin stimulated release of PGF2α and its inhibition by a cyclooxygenase inhibitor and an oxytocin receptor antagonist from equine endometrial cultures.

    Penrod, Leah V; Allen, Ronald E; Rhoads, Michelle L; Limesand, Sean W; Arns, Mark J

    2013-06-01

    Uterine inflammation results in a poor uterine environment and early embryonic loss in the mare due to an inhibition of maternal recognition of pregnancy caused from increased prostaglandin F2α (PGF2α). Oxytocin binds to endometrial cell receptors to activate prostaglandin synthesis. An oxytocin receptor antagonist (Atosiban) and a cyclooxygenase inhibitor (indomethacin) both decrease PGF2α production. The aim of this study was to evaluate the in vitro effects of Atosiban and indomethacin on equine uterine prostaglandin secretion. Equine endometrial explants were harvested on day two of behavioral estrus. Endometrial explant cultures were challenged with oxytocin (250nM) and PGF2α concentrations were measured over time. Explants were also cultured with Atosiban and indomethacin for 6h to determine the influence on PGF2α secretion. When endometrial explants were challenged with oxytocin, PGF2α concentrations were greater (PAtosiban or indomethacin. These findings show equine endometrial explants can be stimulated with oxytocin to increase secretion of PGF2α and this secretion can be inhibited through an oxytocin receptor antagonist and a Cox inhibitor, suggesting that this response to oxytocin involves an oxytocin receptor mediated event that activates the prostaglandin synthesis cascade through cyclooxygenase. Furthermore, this data suggests a role for the use of these inhibitors in vivo to decrease uterine PGF2α secretion and prevent early luteal regression and embryonic loss. PMID:23664650

    2014-01-01

    Objective. Effect of isopropanolic Cimicifuga racemosa extract (iCR) on uterine fibroid size compared with tibolone. Method. The randomized, double-blind, controlled study in China enrolled 244 patients aged 40-60 years with menopausal symptoms (Kupperman Menopause Index ≥ 15). The participants were treated with either iCR of 40 mg crude drug/day (N = 122) or tibolone 2.5 mg/day (N = 122) orally for 3 months in 2004. Now, we investigated the subset of all women (N = 62) with at least one uterine fibroid at onset of treatment for the effect of iCR (N = 34) on fibroid size compared with tibolone (N = 28) by transvaginal ultrasonography. Results. The median myoma volume decreased upon iCR by as much as -30% (P = 0.016) but increased upon tibolone by +4.7%. The percentage of volume change, mean diameter change and geometric mean diameter change of the iCR group compared to tibolone were statistically significant (P = 0.016, 0.021, 0.016 respectively). Conclusion. Our results suggest that iCR (Remifemin) is a valid herbal medicinal product in patients with uterine myomas as it provides adequate relief from menopausal symptoms and inhibits growth of the myomas in contrast to tibolone.

    2016-06-01

    Sulpiride and ethylene glycol monomethyl ether (EGME) are known ovarian toxicants that stimulate prolactin (PRL) secretion, resulting in hypertrophy of the corpora lutea and increased progesterone (P4) production. The purpose of the present study was to investigate how the PRL stimulatory agents affected uterine carcinogenesis and to clarify the effects of PRL on endometrial adenocarcinoma progression in rats. Ten-week-old female Donryu rats were treated once with N-ethyl-N'-nitro-N-nitrosoguanidine (20 mg kg(-1) ), followed by treatment with sulpiride (200 ppm) or EGME (1250 ppm) from 11 weeks of age to 12 months of age. Sulpiride treatment inhibited the incidence of uterine adenocarcinoma and precancerous lesions of atypical endometrial hyperplasia, whereas EGME had no effect on uterine carcinogenesis. Sulpiride markedly prevented the onset of persistent estrus throughout the study period, and EGME delayed and inhibited the onset of persistent estrus. Moreover, sulpiride-treated animals showed high PRL and P4 serum levels without changes in the levels of estradiol-17β, low uterine weights and histological luteal cell hypertrophy. EGME did not affect serum PRL and P4 levels. These results suggest that the prolonged low estradiol-17β to P4 ratio accompanied by persistent estrous cycle abnormalities secondary to the luteal stimulatory effects of PRL may explain the inhibitory effects of sulpiride on uterine carcinogenesis in rats.

    Uterine growth and endometrial gland formation (adenogenesis) and function, are essential for fertility and are controlled by estrogens and other regulators, whose nature and physiological relevance are yet to be elucidated. Kisspeptin, which signals via Kiss1r, is essential for fertility, primarily through its central control of the hypothalamic-pituitary-ovarian axis, but also likely through peripheral actions. Using genetically modified mice, we addressed the contributions of central and peripheral kisspeptin signaling in regulating uterine growth and adenogenesis. Global ablation of Kiss1 or Kiss1r dramatically suppressed uterine growth and almost fully prevented adenogenesis. However, while uterine growth was fully rescued by E2 treatment of Kiss1(-/-) mice and by genetic restoration of kisspeptin signaling in GnRH neurons in Kiss1r(-/-) mice, functional adenogenesis was only marginally restored. Thus, while uterine growth is largely dependent on ovarian E2-output via central kisspeptin signaling, peripheral kisspeptin signaling is indispensable for endometrial adenogenesis and function, essential aspects of reproductive competence.

  9. Endometrial carcinoma stage I.

    Baram, A; Ron, I; Kupferminc, M; Inbar, M

    1997-01-01

    Standard staging and therapeutic approach to endometrial cancer involves lymph node sampling (LNS) at the time of total abdominal hysterectomy (TAH) and bilateral salpingo-oophorectomy (BSO). Lymphadenectomy prolongs time of surgery and increases the risk of morbidity; where other predictors are available, it may not contribute important supplementary information. 185/247 women with stage I endometrial carcinoma underwent the standard surgery while 62 underwent TAH+BSO. Recurrence and survival were monitored for a mean of 6.5 years and retrospectively reviewed: the rates for groups with and without known lymph node status were alike [13.5% (25/185) recurrence for the former and 12.9% (8/62) for the latter, and 5-year survival rates of 75.7% (140/185) for the former and 74.2 (46/62) for the latter]. Myometrial invasion and histological grade appeared to have been highly accurate predictors without lymph node information. Because information on histological grade is available early and is highly predictive, its use could be incorporated into a revised management algorithm for stage I endometrial cancer which would depend upon ensuring lymphadenectomy for women with low grade histopathology and omitting it for those with high grades on the grounds that no further information is necessary to act appropriately.

  10. Should all patients with serous and clear cell endometrial carcinoma receive adjuvant chemotherapy?

    Boren, Todd P; Miller, David S

    2010-11-01

    Uterine papillary serous carcinoma (UPSC) and uterine clear cell carcinoma (UCCC) represent two rare subtypes that have an increased risk of recurrence and worse overall survival compared with the more common endometrioid endometrial cancers. Meaningful data in the form of prospective randomized trials is lacking for both advanced and early-stage UPSC and UCCC. Data extrapolated from prospective trials in advanced endometrioid endometrial cancer and retrospective trials on early-stage UPSC suggest that adjuvant platinum and taxane-based chemotherapy may provide a survival benefit for these patients. Future trials specifically examining UPSC and UCCC are needed to elucidate the optimal treatment regimen for these patients. Given the current data, the option of chemotherapy should be considered in treatment-planning discussions for all patients with UPSC and UCCC. PMID:21118038

  11. Pitfalls in staging uterine neoplasm with imaging: a review.

    Kinkel, K

    2006-01-01

    This review analyzes current pitfalls in pretreatment staging of endometrial and cervical carcinoma with magnetic resonance imaging (MRI) based on a critical review of the literature. Technical, patient, and tumor-related characteristics were analyzed to improve further staging of uterine neoplasm with MRI. For endometrial carcinoma staging, contrast-enhanced dynamic imaging appears essential to avoid false-positive findings for deep myometrial invasion by better delineating tumor from normal myometrium. However, leiomyomas, adenomyosis, and grade 3 tumors provide difficulties in staging for pathologists and radiologists. Slice orientation perpendicular to the long axis of the cervical channel might improve false-negative findings for deep stromal invasion on T2-weighted images in endometrial and cervical cancer. Contrast-enhanced sequences do not improve diagnosis of parametrial or vaginal invasion in cervical cancer. Assessment of lymph node invasion by any imaging modality has limited sensitivity in detecting lymph node metastasis smaller than 5 mm. Knowledge of diagnostic criteria is critical to avoid false-negative findings for bladder wall invasion. Higher spatial resolution with dedicated multichannel pelvic phase array coils, smaller fields of view and section thickness, and careful comparison of T2-weighted and contrast-enhanced sequences are strategies that might avoid misinterpretation of pelvic MRI in staging uterine neoplasm.

  12. Conditional deletion of Sox17 reveals complex effects on uterine adenogenesis and function.

    Guimarães-Young, Amy; Neff, Traci; Dupuy, Adam J; Goodheart, Michael J

    2016-06-15

    The importance of canonical Wnt signaling to murine uterine development is well established. Mouse models in which uterine-specific Wnt ligands, β-catenin, or Lef1 are disrupted result in failure of postnatal endometrial gland development. Sox17 is a transcription factor characterized in numerous tissues as an antagonist of Wnt signaling. Thus, we hypothesized that conditional ablation of Sox17 would lead to hyperproliferation of endometrial glands in mice. Contrary to our prediction, disruption of Sox17 in epithelial and stromal compartments led to inhibition of endometrial adenogenesis and a loss of reproductive capacity. Epithelium-specific Sox17 disruption resulted in normal adenogenesis although reproductive capacity remained impaired. These findings suggest that non-epithelial, Sox17-positive cells are necessary for adenogenesis and that glands require Sox17 to properly function. To our knowledge, these findings are the first to implicate Sox17 in endometrial gland formation and reproductive success. The data presented herein underscore the importance of studying Sox17 in uterine homeostasis and function. PMID:27102016

    Endometriosis is one of the most important causes of infertility; however the precise mechanism by which it affects female fertility is unclear. The objective of this study was to study the functional aspects of the uterus by evaluating uterine contractility in patients with endometrial cysts of the ovary. The study population was recruited from two institutes and consisted of 26 women (periovulatory (10), luteal (13), and menstrual phase (3); age range: 19-51 years) with untreated endometriosis; the control group consisted of 12 healthy women (age range: 22-41 years). Cine MR imaging obtained by a 1.5T magnet was visually evaluated at 12 x faster than real speed, focusing on the presence of uterine peristalsis, the direction and frequency of peristalsis, and the presence of sustained uterine contractions. Uterine peristalsis was identifiable in 3/10, 3/13, and 3/3 of the endometriosis patients in each menstrual cycle, respectively, and in 11/12, 3/12, and 5/12 of their control subjects. Peristaltic detection rate and frequency were significantly less for the endometriosis group than for the controls in the periovulatory phase only (p<0.05). Sustained contractions were recognized in 19/36 control subjects and in 13/26 endometriosis patients, but the difference was not significant. Uterine peristalsis appears to be suppressed during the periovulatory phase in patients with endometriosis, which may have an adverse effect on sperm transport. (orig.)

  1. Diagnostic and prognostic markers for uterine diseases in dogs.

    Hagman, R

    2014-06-01

    Common uterine diseases in female dogs include cystic endometrial hyperplasia (CEH), mucometra, hydrometra and pyometra. It is important in clinical practice to recognize pyometra because it is potentially life-threatening due to the systemic illness induced by bacterial infection of the uterus. In contrast, the uterine content is sterile in CEH and mucometra/hydrometra, and clinical signs are mostly mild or absent. Optimal treatment depends on the type of uterine disease and its severity, but diagnosis and prognosis determination may be challenging and the diseases difficult to separate clinically. Diagnostic findings or biomarkers that may aid in the differentiation of the diseases are valuable, especially when several bitches are admitted with a fluid-filled uterus during night-time, and it has to be decided which patient to operate on first. Additionally, some variables may indicate outcome as measured by mortality or morbidity. If the uterus is not enlarged or fluid-filled, detection of uterine disease can be even more difficult. In this study, clinically useful variables with possible diagnostic or prognostic value for uterine diseases in dogs are discussed. PMID:24947856

    In mares, mating-induced persistent endometritis contributes to low fertility. The condition is in part related to delayed clearance of mucus accumulated within the uterine lumen. The objective of this study was to investigate the endometrial response of healthy mares to intrauterine (i.u.) treatment with N-acetylcysteine (NAC). Oestrous mares (n = 12) were randomly assigned to a treatment (TM) or control (C) group and received an i.u. infusion of 5% NAC and saline (total volume 140 ml), respectively. Endometrial biopsies were collected in five of the mares 24 h after treatment, in the remaining seven mares 72 h after treatment. Endometrial biopsies were evaluated for integrity of the luminal epithelium, number of polymorphonuclear neutrophils (PMN), staining for cyclooxygenase 2 (COX2), staining with Kiel 67 antigen (Ki-67), lectins and periodic acid-Schiff (PAS). The integrity of endometrial epithelial cells was not affected by treatment (no statistical differences between groups or times). At 24 h after treatment, the mean number of PMN in endometrial biopsies from NAC- and C-mares did not differ, but at 72 h after treatment, number of PMN was significantly higher (p NAC-treated mares (2.3 ± 0.2 PMN/field). At 72 h after treatment, the intensity of staining for COX2 was significantly higher after saline than after NAC treatment (p NAC-treated mares than in C-mares 72 h after treatment (p mucus in deep uterine glands differed significantly between groups at 24 h after treatment (p NAC does not adversely affect the endometrial function. Moreover, an anti-inflammatory effect on the equine endometrium was observed. PMID:23186260

  4. Pregnancy Following Uterine Artery Embolization with Polyvinyl Alcohol Particles for Patients with Uterine Fibroid or Adenomyosis

    Purpose:To determine whether uterine fibroid embolization (UFE) with polyvinyl alcohol (PVA) particles affects fertility in women desiring future pregnancy.Methods:Of 288 patients managed with UFE with PVA particles for uterine myoma or adenomyosis between 1998 and 2001, 94 patients were enrolled in this study. The age range of participants was 20-40 years. The data were collected through review of medical records and telephone interviews. Mean duration of follow-up duration was 35 months (range 22-60 months). Patients using contraception and single women were excluded, and the chance of infertility caused by possible spousal infertility or other factors was disregarded. Contrast-enhanced magnetic resonance imaging was performed in all patients before and after UFE, and the size of PVA particles used was 255-700 μm.Results:Among 94 patients who underwent UFE with PVA, 74 were on contraceptives, 6 had been single until the point of interview, and 8 were lost to follow-up. Of the remaining 6 patients who desired future pregnancy, 5 (83%) succeeded in becoming pregnant (1 patient became pregnant twice). Of a total of 8 pregnancies, 6 were planned pregnancies and 2 occurred after contraception failed. Five deliveries were vaginal, and 2 were by elective cesarean. Artificial abortion was performed in 1 case of unplanned pregnancy. There was 1 case of premature rupture of membrane (PROM) followed by preterm labor and delivery of an infant who was small-for-gestational-age. After UFE, mean volume reduction rates of the uterus and fibroid were 36.6% (range 0 to 62.6%) and 69.3% (range 36.3% to 93.3%), respectively.Conclusion:Although the absolute number of cases was small, UFE with PVA particles ultimately did not affect fertility in the women who underwent the procedure

  5. Laparoscopic hysterectomy in the treatment of endometrial cancer: NCI experience

    The standard treatment for women with endometrial cancer is total abdominal hysterectomy and pelvic lymphadenectomy for surgical staging. Total laparoscopic radical hysterectomy (TLH) is an alternative approach providing surgical and patient related advantages to laparoscopy. Methods: Twenty female patients with early stage endometrial cancer were operated upon by TLH and pelvic lymphadenectomy, aiming to assess the safety and efficacy of TLH. Results: The mean operative time was 296.8 min conversion to laparotomy was done in one patient due to bleeding from the uterine vessels. The mean blood loss was 517.5 cc. The uterus was removed transvaginally in 18 patients (90%) and via a small Pfannenstiel incision in two patients (10%). The mean number of pelvic lymph nodes retrieval was 21.2. Postoperative bleeding occurred in one patient (5%) which necessitated exploration. One patient (5%) suffered a pulmonary embolism. Four patients (20%) developed pyrexia, and one patient (5%) suffered from a chest infection. One patient (5%) had wound infection. The mean hospital stay was 4.5 days (range 3-10). Conclusion: TLH with pelvic lymphadenectomy is a safe and effective approach in the treatment of early endometrial carcinoma.

    Background: HOXA11 and HOXA10 are expressed in endometrium throughout the menstrual cycle and show a dramatic increase during the mid-luteal phase at the time of implantation. The expression of these genes is decreased in women with myomas. Objective: To determine whether myomectomy would reverse HOXA11 and HOXA10 expression, we evaluated the transcript levels of these genes in the endometria of patients before and after myomectomy. Materials and Methods: Expression of HOXA11 and HOXA10 were examined prospectively during the midluteal phase in endometrium obtained from infertile women (n=12) with myoma before and three months after myomectomy. Endometrial HOXA11 and HOXA10 expression were evaluated using quantitative real-time reverse transcriptase-polymerase chain reaction (RT-PCR). Results: Endometrial HOXA11 and HOXA10 mRNAs expression levels (normalized to 18SrRNA) were increased insignificantly in endometrium of patients after myomectomy (p=0.7 and p=0.15 respectively). Conclusion: The results suggest that the alteration in expression pattern of these genes could not account for some aspects of fertility after myomectomy. This article extracted from M.Sc. thesis.

  7. Adrenal Metastasis from Uterine Papillary Serous Carcinoma.

    Singh Lubana, Sandeep; Singh, Navdeep; Tuli, Sandeep S; Seligman, Barbara

    2016-01-01

    BACKGROUND Uterine papillary serous carcinoma (UPSC) is a highly malignant form of endometrial cancer with a high propensity for metastases and recurrences even when there is minimal or no myometrial invasion. It usually metastasizes to the pelvis, retroperitoneal lymph nodes, upper abdomen, and peritoneum. However, adrenal metastases from UPSC is extremely rare. Here, we present a case of UPSC with adrenal metastasis that occurred 6 years after the initial diagnosis. CASE REPORT A 60-year-old woman previously diagnosed with uterine papillary serous carcinoma at an outside facility presented in September of 2006 with postmenopausal bleeding. She underwent comprehensive surgical staging with FIGO (International Federation of Gynecology and Obstetrics) stage 2. Post-operatively, the patient was treated with radiation and chemotherapy. The treatment was completed in April of 2007. The patient had no evidence of disease until July 2009 when she was found to have a mass highly suspicious for malignancy. Subsequently, she underwent right upper lobectomy. The morphology of the carcinoma was consistent with UPSC. She refused chemotherapy due to a previous history of chemotherapy-induced neuropathy. The patient was followed up with regular computed tomography (CT) scans. In October 2012 a new right adrenal nodule was seen on CT, which showed intense metabolic uptake on positron emission tomography (PET)/CT scan. The patient underwent right adrenalectomy. Pathology of the surgical specimen was consistent with UPSC. CONCLUSIONS UPSC is an aggressive variant of endometrial cancer associated with high recurrence rate and poor prognoses. Long-term follow-up is needed because there is a possibility of late metastases, as in this case. PMID:27117594

    RF治疗后又改子宫切除者。结论RF治疗功血安全、有效和微创;对病变内膜的直接热凝固使内膜失活和纤维化,是RF治疗功血远期有效和防止复发的重要机制。%Objective To investigate long-term effect on radiofrequency heat-coagulation (RF)endometrial ablation in treatment of anovulatory dysfunctional uterine bleeding (DUB). Methods From Jul.2001 to Nov. 2009, 1 196 patients with DUB who were failed by medical treatment( including 127 patients with dysmenorrheal) were enrolled into this study in Jinan Millitary General HospitaL Those patients were divided into two groups according to age:427 patients at age of or more than 45 years (average age 48 years) in Group A who were treated by RF procedure for amenorrhea;769 patients at age of less than 45 years old (average 37 years) in group B were treated by RF for controlling excessive menstrual bleeding. All the patients had the results of menstrual score (pictorial blood loss assessment chart, PBAC), hemoglobin (Hb) ,endometrial curettage pathology and hysteroscopy examination immediately after RF procedure; Some patients still had another endometrial curettage pathology and clinical results in 6 months after RF. The mean follow-up time was 72 months ( range:6 to 100 months). The evaluation criterion for RF treatment was to use optimal and significant effect measurements. For group A, the optimal treatment effect (cure) was defined as bleeding cessation and achieving amenorrhea that continued for more than 12 months after treatment. For group B, the optimal treatment effect (cure) was also defined as bleeding cessation and resuming normal menstruation which continued for more than 12 months after treatment. Significant treatment effect was defined as irregular, minor bleeding, but PBAC score less than 100 within 12 months. If patient symptoms and PBAC scores did not change compared with those before treatment, the treatment was defined as failure. For dysmenorrhea, the

  9. Molecular characterisation of the uterine microbiome of dairy cows suffering from endometritis, metritis, and pyometra

    Knudsen, Lif Rødtness Vesterby

    Postpartum uterine disease is a problem in dairy herds. Approximately 90% of dairy cows experience postpartum bacterial contamination of the uterus. Most of the cows are able to clear the infection within 8 weeks in the process of involution, but up to 20% of the cows develop metritis, which is...... infection throughout the uterine wall; and in some herds, 30-50% of cows develop endometritis, which is infection in the inner lining of the uterus. Pyometra is a related postpartum uterine disease, which is thought to occur when a cow with endometritis ovulates, and the cervix closes. The diseases are...... the mucosal layer of the uterus, the endometrium. It was hypothesised that pathogenic bacteria in the uterus initially adhere to the endometrium to cause disease, and that the chance of identifying pathogens is higher in examinations of endometrial biopsies than in uterine flush samples. In order to...

  10. Uterine Balloon Tamponade in Combination with Topical Administration of Tranexamic Acid for Management of Postpartum Hemorrhage

    Masato Kinugasa

    2015-01-01

    Full Text Available While uterine balloon tamponade is an effective modality for control of postpartum hemorrhage, the reported success rates have ranged from the level of 60% to the level of 80%. In unsuccessful cases, more invasive interventions are needed, including hysterectomy as a last resort. We developed a modified tamponade method and applied it to two cases of refractory postpartum hemorrhage after vaginal delivery. The first case was accompanied by uterine myoma and low-lying placenta. After an induced delivery, the patient had excessive hemorrhage due to uterine atony. Despite oxytocin infusion and bimanual uterine compression, the total blood loss was estimated at 2,800 mL or more. The second case was diagnosed as placental abruption complicated by fetal death and severe disseminated intravascular coagulation, subsequently. A profuse hemorrhage continued despite administration of uterotonics, fluid, and blood transfusion. The total blood loss was more than 5,000 mL. In each case, an intrauterine balloon catheter was wrapped in gauze impregnated with tranexamic acid, inserted into the uterus, and inflated sufficiently with sterile water. In this way, mechanical compression by a balloon and a topical antifibrinolytic agent were combined together. This method brought complete hemostasis and no further treatments were needed. Both the women left hospital in stable condition.

    Women with metabolic disorders, including obesity and diabetes, have an increased risk of developing endometrial cancer. However, the metabolism of endometrial tumors themselves has been largely understudied. Comparing human endometrial tumors and cells with their nonmalignant counterparts, we found that upregulation of the glucose transporter GLUT6 was more closely associated with the cancer phenotype than other hallmark cancer genes, including hexokinase 2 and pyruvate kinase M2. Importantly, suppression of GLUT6 expression inhibited glycolysis and survival of endometrial cancer cells. Glycolysis and lipogenesis were also highly coupled with the cancer phenotype in patient samples and cells. To test whether targeting endometrial cancer metabolism could be exploited as a therapeutic strategy, we screened a panel of compounds known to target diverse metabolic pathways in endometrial cells. We identified that the glycolytic inhibitor, 3-bromopyruvate, is a powerful antagonist of lipogenesis through pyruvylation of CoA. We also provide evidence that 3-bromopyruvate promotes cell death via a necrotic mechanism that does not involve reactive oxygen species and that 3-bromopyruvate impaired the growth of endometrial cancer xenografts.

  15. Endometrial Histology of Depomedroxyprogesterone Acetate Users: A Pilot Study

    2006-01-01

    Full Text Available Objective. To obtain pilot data on the endometrial histology of Depomedroxyprogesterone acetate (Depo-Provera, DMPA users experiencing breakthrough bleeding (BTB versus users with amenorrhea. To compare the endometrial histology of patients who used DMPA continuously for 3–12 months versus those who used it for 13 months or more. Methods. Cross-sectional study. Endometrial biopsy was obtained from all consenting patients who used DMPA for at least 3 months. Patients were divided into those with BTB in the last 3 months versus those with amenorrhea for at least 3 months. Histology results and duration of therapy were compared. Results. The proportion of women with chronic endometritis, uterine polyps, atrophic, proliferative, or progesterone-dominant endometrium did not differ between those DMPA users with BTB versus those with amenorrhea. Duration of therapy did not correlate with symptoms of BTB or endometrial histology. Chronic endometritis was the most common histologic finding (10/40, 25% and occurred more often in women experiencing BTB (35% versus 15% (RR 1.62 CI 0.91–2.87. Moreover, 45% of women with BTB had received DMPA for more than 12 months. Conclusions. BTB was more common than previously reported in women using DMPA for more than 12 months. Chronic endometritis, which may indicate an underlying infectious or intracavitary anatomic etiology, has not been previously reported as a frequent finding in DMPA users, and may be related to ethnic or other sociodemographic characteristics of our patient population. Further study to elucidate the etiology of chronic endometritis in these patients is warranted.

  16. ANTEMORTEM DIAGNOSIS OF CYSTIC ENDOMETRIAL HYPERPLASIA AND SUCCESSFUL OVARIOHYSTERECTOMY IN AN AFRICAN WARTHOG (PHACOCHOERUS AFRICANUS).

    Thompson, Kimberly A; Niehaus, Andrew; Shellabarger, Wynona; Depenbrock, Sarah; Agnew, Dalen

    2015-12-01

    During a routine geriatric examination on a 9-yr-old, nulliparous female African warthog (Phacochoerus africanus), a severely enlarged, mixed echogenicity uterus was discovered during transabdominal ultrasound. Ovariohysterectomy (OVH) was elected and performed due to concern for a potential neoplastic condition. Postoperatively, the warthog was treated prophylactically with metoclopramide and ranitidine to promote gastrointestinal motility and prevent postoperative ileus. The gross appearance and histopathology confirmed the presence of extensive widely disseminated cystic changes consistent with cystic endometrial hyperplasia (CEH) and multiple para-ovarian cysts. Uterine pathology, including CEH, is a common condition in domestic potbellied pigs (Sus scrofa), and as a result, it is recommended to perform an OVH at an early age. The advanced uterine changes may have accounted for this animal's history of infertility. This case provides evidence that nulliparity may be associated with the development of uterine pathology in warthogs. Increased knowledge of reproductive pathology will aid in improved management strategies for breeding nondomestic suids. PMID:26667548

    2016-03-01

    The aim of this study was to evaluate the uterine blood supply and endometrial vessel architecture, during the equine estrous cycle. Narrow Band Imaging (NBI) hysteroscopy was used for evaluating changes in the endometrial vasculature during the estrous cycle [six mares, d 0 (representing the day of ovulation), d 6 and 11 in four locations]. In addition, endometrial biopsy samples were used for immunodetection of markers for angiogenesis (Vascular Endothelial Growth Factor A, its receptor 2, as well as angiopoietin-2 and its receptor-tyrosine-kinase Tie2) during the estrous cycle (three mares, d 0, 5 and 10; one biopsy per mare). Detailed analysis of hysteroscopic images revealed an increase in the vascular density from estrus towards diestrus. In contrast, microscopic specimens prepared from biopsies revealed no evidence for changes in the endometrial vessel number during the estrous cycle. Studies on expression of angiogenesis markers indicated that cyclic changes in the endometrial vascular density observed by NBI-hysteroscopy were not due to formation of new vessels. It is concluded that vessels are involved in blood supply of a smaller area during diestrus, facilitating better distribution of nutrients during this phase. PMID:26791330

The aim of this study was to identify the preoperative, intraoperative, and postoperative characteristics of women undergoing vaginal hysterectomy in the absence of uterine prolapse.Methods: A prospective, descriptive, quantitative, noncomparative study was conducted in 117 women between August 2009 and February 2011 in Petropolis, Rio de Janeiro, Brazil. The women included had a uterine indication for hysterectomy, their surgeries were performed by the same team, and they were followed up for 12 months. An adapted Pelvic Organ Prolapse Quantification system was used to check for uterine prolapse.Results: The age range of the women was 33–59 years, uterine volume was 300–900 mL, and 73.50% has undergone prior cesarean section. The main indication for hysterectomy was uterine myoma (64.95%, with a surgery time of 30–60 minutes in 55 (59.82% and 19 (15.98% cases, respectively. Uterine volume reduction was performed in 41 (35.05% cases, salpingectomy was the most common associated surgery (81.19%, and anesthesia was subdural (68.37%. Common intraoperative complications included bladder lesions (8.54%, with conversion to the abdominal route being necessary in one case (1.28%, and the most common postoperative complication being vaginal

    Full Text Available Uterine leiomyoma is the most common benign tumor of genital tract. The etiology of myomasis unknown. Leiomyoma shows a broad spectrum of radiographic appearances depending on thenumber, size, and location of the tumor. The diagnostic method for uterine leiomyomas is basedprimarily on the clinical situation. Despite of the varied diagnostic options such as; transvaginalsonography, sonohysterography, hysteroscopy, laparoscopy and MRI; hysterosalpingography isstill one of the valuable imaging methods for identification of uterine leiomyoma.The various features of the proved leiomyoma are illustrated in this pictorial review. The incidence,risk factors and clinical features will also be discussed briefly.

    2015-02-01

    Full Text Available Background: Objectives of current study were to diagnose causes of Abnormal Uterine Bleeding (AUB in postmenopausal women (PMW and to correlate it with curettage and histopathological findings, hysteroscopy and thereby minimizing unnecessary interventions in the form of operations and hysteroscopy where sonography depicts normal findings. Methods: After obtaining ethical clearance present prospective observational study was conducted from November 2010 to November 2012, to evaluate the endometrium in 50 postmenopausal women (PMW with bleeding per vagina referred to the department of Radio diagnosis by the department of gynaecology in Bangalore medical college and research institute. After applying inclusion and exclusion criterias the cases were evaluated with ultrasonography both transabdominal (TAS and transvaginal scan (TVS where ever necessary. Histopathological and hysteroscopic correlation was done in all cases. Results: 58% of the PMW with bleed were in the age group of 51-60 years. Most common cause of PMB was atrophic endometrium (44%, endometrial polyp (22%, followed by malignancy (14%, and hyperplastic endometrium (6%. At Endometrium thickness less than 4 mm there were nil chances of carcinoma. Conclusions: In women with AUB in postmenopausal age ultrasonography (USG can be considered as an initial imaging modality for diagnosing endometrial diseases. The sensitivity and specificity of USG for Atrophic endometrium is 100% and 84% respectively with accuracy of 100%, endometrial polyp the specificity is 100% with accuracy of 88%. For malignancy USG showed 100% specificity and accuracy of 100%. Hence USG is highly accurate for evaluating endometrial pathologies. Being noninvasive, less costly and good patient compliance USG should be considered as an initial imaging modality over invasive investigations like D and C, hysteroscopy in evaluating endometrial disorders.

  19. Differentiation of the various lesions causing an abnormality of the endometrial cavity using MR imaging: emphasis on enhancement patterns on dynamic studies and late contrast-enhanced T1-weighted images

    The objectives of this study were to determine the usefulness of magnetic resonance (MR) imaging in the differentiation of various lesions causing an abnormality of the endometrial cavity by evaluating the imaging features on dynamic contrast-enhanced study and late contrast-enhanced T1-weighted images (T1WI). Contrast-enhanced MR imaging of 59 pathologically proven lesions that showed an abnormality of the endometrial cavity, including 32 endometrial cancers, five sarcomas, nine hyperplastic polyps, nine submucosal myomas, three hyperplasia, and one adenomyoma, were retrospectively reviewed. The enhancement degree and patterns on dynamic contrast-enhanced study and late contrast-enhanced T1WI were compared among different pathologies. On dynamic contrast-enhanced study, 72% (23/32) of endometrial cancers showed early peak enhancement to be reached within 1 min following intravenous administration of contrast material. On late-contrast-enhanced T1WI, lesions showed weak enhancement with gradual washout. Ninety-five percent (21/22) of benign lesions and 100% (5/5) of sarcomas showed late peak enhancement to be reached in 2-3 min following intravenous administration of contrast material. On late contrast-enhanced T1WI, both of these lesions showed persistent strong enhancement. Different enhancement patterns on dynamic contrast-enhanced MR imaging and late contrast-enhanced T1WI can provide a useful clue in the differentiation of various lesions causing an abnormality of the endometrial cavity.

    2016-01-01

    Uterine tumors with sex-cord-like differentiation are extremely rare types of uterine stromal neoplasm. These tumors were classified into two groups with considerable practical relevance because clinical behaviour of uterine tumor resembling ovarian sex cord tumor (UTROSCT) differs widely from its closely related endometrial stromal tumors with sex-cord-like elements (ESTSCLE). Treatment and prognosis of these tumors are unresolved issues because of the exiguous number of reported cases. We describe a rare case of endometrial stromal tumor with sex-cord-like differentiation successfully treated by resectoscopic surgery and conservation of the uterus, in an infertile patient affected by metrorrhagia. This procedure resulted in a pregnancy immediately after treatment and in a successful delivery. During 60 months of follow-up no evidence of recurrence was observed. PMID:27213063

  2. Percutaneous laser-induced interstitial thermotherapy (LITT) for the treatment of very large uterine leiomyomas

    Chapman, Roxana

    1997-05-01

    The success of treating tumors of the liver under local anaesthesia and ultrasound and computered tomography control by mens of the diode laser of 810 nm wavelength with fiber splitter and multiple fibers suggested this form of LITT might be suitable for the treatment of very large leiomyomas where laparoscopy was not possible. The immediate effect of LITT was to produce a large volume of coagulation within the myomas, to destroy the oestrogen receptors and to coagulate the surrounding blood vessels. After one month the coagulated volume had been converted into a jelly-like substance and the zone surrounding this had started to degenerate because of the destruction of its blood vessels which had resulted in local tissue anoxia. Three months later the central coagulum and surrounding zone had been partially absorbed and the whole volume of myoma treated had shrunk to a quarter of the original size. It has thus been shown that a minimally invasive method for the destruction of very large uterine leiomyomas can be safely performed, but further research is required before its general adoption.

    2016-01-01

    Background Extensive uterine adaptations, including angiogenesis, occur prior to implantation in early pregnancy and are potentially regulated by the peptide hormone relaxin. This was investigated in two studies. First, we took a microarray approach using human endometrial stromal (HES) cells treated with relaxin in vitro to screen for target genes. Then we aimed to investigate whether or not relaxin deficiency in mice affected uterine expression of representative genes associated with angiog...

  6. Studies on the diagnosis of uterine body cancer using S Tl-chloride

    Watanabe, Hiraku

    1985-03-01

    S Tl scintigraphy was performed in 18 patients with cancer of uterine body, and the results were compared with histopathological findings. With six patients, S Tl distribution in the pelvic cavity was registered in the minicomputer, and the time activity curve was plotted. Analysis of S Tl distribution using ROI revealed that the radioactivity in the uterus was approximately 1.47 times as high as that in background. In the removed uterus, the radioactivity in the cancer was calculated to be approximately 1.9 times as high as that in the myometrium. In all 13 patients with Stage Ib or higher cancer, obvious activity in the uterus coinciding with the lesion was obtained shortly after the intravenous administration of S Tl-Cl. Though accumulation of activity in the uterus was obtained in three of five patients with Stage Ia cancer, it was interpreted as false-positive, because myoma or adenomyosis was present in addition to cancer in these three patients, and such a complication seemed responsible for the positive result. The sensitivity, specificity and accuracy of S Tl scintigraphy in diagnosing cancer of the uterine body were 86.7, 0 and 72.2%, respectively. These results suggest that S Tl scintigraphy is a promising diagnostic aid for cancer of the uterine body.

  8. Acute puerperal uterine inversion

    Objective: To determine the frequency, causes, clinical presentations, management and maternal mortality associated with acute puerperal inversion of the uterus. Materials and Methods: All the patients who developed acute puerperal inversion of the uterus either in or outside the JPMC were included in the study. Patients of chronic uterine inversion were not included in the present study. Abdominal and vaginal examination was done to confirm and classify inversion into first, second or third degrees. Results: 57036 deliveries and 36 acute uterine inversions occurred during the study period, so the frequency of uterine inversion was 1 in 1584 deliveries. Mismanagement of third stage of labour was responsible for uterine inversion in 75% of patients. Majority of the patients presented with shock, either hypovolemic (69%) or neurogenic (13%) in origin. Manual replacement of the uterus under general anaesthesia with 2% halothane was successfully done in 35 patients (97.5%). Abdominal hysterectomy was done in only one patient. There were three maternal deaths due to inversion. Conclusion: Proper education and training regarding placental delivery, diagnosis and management of uterine inversion must be imparted to the maternity care providers especially to traditional birth attendants and family physicians to prevent this potentially life-threatening condition.

  9. Rac1 Regulates Endometrial Secretory Function to Control Placental Development.

    Juanmahel Davila

    2015-08-01

    Full Text Available During placenta development, a succession of complex molecular and cellular interactions between the maternal endometrium and the developing embryo ensures reproductive success. The precise mechanisms regulating this maternal-fetal crosstalk remain unknown. Our study revealed that the expression of Rac1, a member of the Rho family of GTPases, is markedly elevated in mouse decidua on days 7 and 8 of gestation. To investigate its function in the uterus, we created mice bearing a conditional deletion of the Rac1 gene in uterine stromal cells. Ablation of Rac1 did not affect the formation of the decidua but led to fetal loss in mid gestation accompanied by extensive hemorrhage. To gain insights into the molecular pathways affected by the loss of Rac1, we performed gene expression profiling which revealed that Rac1 signaling regulates the expression of Rab27b, another GTPase that plays a key role in targeting vesicular trafficking. Consequently, the Rac1-null decidual cells failed to secrete vascular endothelial growth factor A, which is a critical regulator of decidual angiogenesis, and insulin-like growth factor binding protein 4, which regulates the bioavailability of insulin-like growth factors that promote proliferation and differentiation of trophoblast cell lineages in the ectoplacental cone. The lack of secretion of these key factors by Rac1-null decidua gave rise to impaired angiogenesis and dysregulated proliferation of trophoblast cells, which in turn results in overexpansion of the trophoblast giant cell lineage and disorganized placenta development. Further experiments revealed that RAC1, the human ortholog of Rac1, regulates the secretory activity of human endometrial stromal cells during decidualization, supporting the concept that this signaling G protein plays a central and conserved role in controlling endometrial secretory function. This study provides unique insights into the molecular mechanisms regulating endometrial secretions

  11. BVDV alters uterine prostaglandin production during pregnancy recognition in cows.

    Embryonic mortality in cows is at least in part caused by failure of pregnancy recognition (PR). Evidence has shown that bovine viral diarrhoea virus (BVDV) infection can disrupt pregnancy. Prostaglandins (PG) play important roles in many reproductive processes, such as implantation. The aim of this study was to investigate the effect of BVDV infection on uterine PG production and PR using an in vitro PR model. Bovine uterine endometrial cells isolated from ten BVDV-free cows were cultured and treated with 0 or 100ng/mL interferon-τ (IFNT) in the absence or presence of non-cytopathic BVDV (ncpBVDV). PGF2α and PGE2 concentrations in the spent medium were measured using radioimmunoassays, and in the treated cells expression of the genes associated with PG production and signalling was quantified using qPCR. The results showed that the IFNT challenge significantly stimulated PTGS1 and PTGER3 mRNA expression and PGE2 production; however, these stimulatory effects were neutralised in the presence of ncpBVDV infection. ncpBVDV infection significantly increased PTGS1 and mPGES1 mRNA expression and decreased AKR1B1 expression, leading to increased PGE2 and decreased PGF2α concentrations and an increased PGE2:PGF2α ratio. The other tested genes, including PGR, ESR1, OXTR, PTGS2, PTGER2 and PTGFR, were not significantly altered by IFNT, ncpBVDV or their combination. Our study suggests that BVDV infection may impair PR by (1) inhibiting the effect of IFNT on uterine PG production and (2) inducing an endocrine switch of PG production from PGF2α to PGE2 to decrease uterine immunity, thereby predisposing the animals to uterine disease.

  12. Peritoneal dissemination complicating morcellation of uterine mesenchymal neoplasms.

    Michael A Seidman

    Full Text Available BACKGROUND: Power morcellation has become a common technique for the minimally invasive resection of uterine leiomyomas. This technique is associated with dissemination of cellular material throughout the peritoneum. When morcellated uterine tumors are unexpectedly found to be leiomyosarcomas or tumors with atypical features (atypical leiomyoma, smooth muscle tumor of uncertain malignant potential, there may be significant clinical consequences. This study was undertaken to determine the frequency and clinical consequence of intraperitoneal dissemination of these neoplasms. METHODOLOGY/PRINCIPAL FINDINGS: From 2005-2010, 1091 instances of uterine morcellation were identified at BWH. Unexpected diagnoses of leiomyoma variants or atypical and malignant smooth muscle tumors occurred in 1.2% of cases using power morcellation for uterine masses clinically presumed to be "fibroids" over this period, including one endometrial stromal sarcoma (ESS, one cellular leiomyoma (CL, six atypical leiomyomas (AL, three smooth muscle tumor of uncertain malignant potential (STUMPs, and one leiomyosarcoma (LMS. The rate of unexpected sarcoma after the laparoscopic morcellation procedure was 0.09%, 9-fold higher than the rate currently quoted to patients during pre-procedure briefing, and this rate may increase over time as diagnostically challenging or under-sampled tumors manifest their biological potential. Furthermore, when examining follow-up laparoscopies, both from in-house and consultation cases, disseminated disease occurred in 64.3% of all tumors (zero of one ESS, one of one CL, zero of one AL, four of four STUMPs, and four of seven LMS. Only disseminated leiomyosarcoma, however, was associated with mortality. Procedures are proposed for pathologic evaluation of morcellation specimens and associated follow-up specimens. CONCLUSIONS/SIGNIFICANCE: While additional study is warranted, these data suggest uterine morcellation carries a risk of disseminating

Genome-wide imputation and meta-analysis identified five new risk loci of genome-wide significance at likely regulatory regions on chromosomes 13q22.1 (rs11841589, near KLF5), 6q22.31 (rs13328298, in LOC643623 and near HEY2 and NCOA7), 8q24.21 (rs4733613, telomeric to MYC), 15q15.1 (rs937213, in EIF2AK4, near BMF) and 14q32.33 (rs2498796, in AKT1, near SIVA1). We also found a second independent 8q24.21 signal (rs17232730). Functional studies of the 13q22.1 locus showed that rs9600103 (pairwise r(2) = 0.98 with rs11841589) is located in a region of active chromatin that interacts with the KLF5 promoter region. The rs9600103[T] allele that is protective in endometrial cancer suppressed gene expression in vitro, suggesting that regulation of the expression of KLF5, a gene linked to uterine development, is implicated in tumorigenesis. These findings provide enhanced insight into the genetic and biological basis of endometrial cancer. PMID:27135401

    Alexander Swidsinski

    Full Text Available OBJECTIVE: To assess whether the bacterial vaginosis biofilm extends into the upper female genital tract. STUDY DESIGN: Endometrial samples obtained during curettage and fallopian tube samples obtained during salpingectomy were collected. Endometrial and fallopian tube samples were analyzed for the presence of bacteria with fluorescence-in-situ-hybridisation (FISH analysis with probes targeting bacterial vaginosis-associated and other bacteria. RESULTS: A structured polymicrobial Gardnerella vaginalis biofilm could be detected in part of the endometrial and fallopian tube specimens. Women with bacterial vaginosis had a 50.0% (95% CI 24.0-76.0 risk of presenting with an endometrial Gardnerella vaginalis biofilm. Pregnancy (AOR  = 41.5, 95% CI 5.0-341.9, p<0.001 and the presence of bacterial vaginosis (AOR  = 23.2, 95% CI 2.6-205.9, p<0.001 were highly predictive of the presence of uterine or fallopian bacterial colonisation when compared to non-pregnant women without bacterial vaginosis. CONCLUSION: Bacterial vaginosis is frequently associated with the presence of a structured polymicrobial Gardnerella vaginalis biofilm attached to the endometrium. This may have major implications for our understanding of the pathogenesis of adverse pregnancy outcome in association with bacterial vaginosis.

    Yoshida, Midori; Inoue, Kaoru; Takahashi, Miwa

    2015-10-01

    Endometrial adenocarcinoma in the uterine corpus is a malignant cancer that occurs in menopausal women and aged rodents. Because of the similarities in pathogenesis and morphology of endometrial adenocarcinoma in rodents and humans, prediction of the modes of action (MOA) in uterine carcinogenesis is important for extrapolation of rodent data to humans. Three MOAs have been accepted as major pathways for uterine carcinogenesis in rodents: 1) estrogenic activity, 2) increased serum 17beta-estradiiol (E2) to progesterone (P4) ratio and 3) modulation of estrogen metabolism to produce 4-hydroxyestradiol via P450 induction. Inhibition of estrogen excretion and increased aromatase in situ in the tumor are also a potential pathway. Here, chemicals showing uterine carcinogenicity were chosen from approximately 300 pesticides evaluated in Japan within the past decade, and their mechanisms were predicted using parameters from mechanistic and toxicity studies. Seven pesticides increased uterine tumor formation in rats, and the pathways of 4 pesticides could be predicted based on various mechanistic studies. The MOAs of cyenopyrafen and benthiavalicarb-isopropyl were predicted to be modulation of estrogen metabolism, while those of pyriminobac-methyl and spirodiclofen were predicted to be increased E2 to P4 ratio. The driven pathways of metazosulfuron and isopyrazam could not be predicted using several mechanistic studies. No mechanistic studies have been reported for sedaxane, which has a chemical structure and toxicological profile similar to isopyrazam. Our results indicated that appropriate mechanistic studies are useful for mechanism prediction in risk assessment. From this analysis, a flowchart showing a decision tree for predictive MOAs in uterine carcinogenesis was proposed. PMID:26538810

  16. Endometrial Cholesterol Granuloma Associated with Prolapsed Uterus- A Rare Case Report with Unusual Clinical Presentation.

    Sumathi, S

    2016-03-01

    Cholesterol granuloma is a chronic inflammatory reaction to cholesterol deposition. It may develop in variety of sites including middle ear, mastoid process, para nasal sinuses, mediastinum, breast, testis and kidney. But endometrial cholesterol granuloma is a rarely reported case and is usually presented clinically as pyometra. This article reports a case of cholesterol granuloma in the endometrium associated with prolapsed uterus. In this case the patient clinically presented with urinary retention and overflow incontinence of urine. The reason of acute urinary retention in this case was pelvic fibrosis and adhesion secondary to this chronic inflammatory reaction. This was supported by the presence of pus like yellowish material over the uterine surface and pelvic adhesion, noted during surgery. Endometrial biopsy revealed cholesterol granuloma that confirmed the source of chronic inflammatory reaction and pelvic fibrosis. PMID:27134881

    The objective of this study was to investigate the effect of time of first postpartum ovulation on endometrial inflammation in dairy cows with and without uterine disease during the early puerperal period. Transvaginal follicular puncture (FP) was carried out to suppress postpartum ovulation and formation of a CL until Day 42. Fifty-three lactating Holstein Friesian cows were divided into four groups on the basis of presence (UD+) or absence (UD-) of uterine disease, which was defined as retained fetal membranes and/or metritis, and whether FP had (FP+) or had not been (FP-) carried out. This resulted in the following groups: UD-FP- (n = 15), UD-FP+ (n = 13), UD+FP- (n = 13), and UD+FP+ (n = 12). Cloprostenol was given on Days 55 to 60 postpartum, and GnRH was administered 2 days later for synchronization of ovulation. In the FP- groups, endometrial swab and biopsy samples were collected during the second estrus (approximately Day 40) and during the estrus after synchronization. In the FP+ groups, the same samples were collected during the first estrus (approximately Day 49) and during the estrus after synchronization. The prevalence of positive bacteriologic cultures of the endometrium was not affected by FP (P > 0.05). Histologic signs of endometritis were more severe in UD+FP- cows at second sampling than in UD+FP+ cows (P ≤ 0.05). Endometrial expression of IL1α (in UD- after first sampling and in UD+ after second sampling) and IL1β (in UD- and UD+ after first sampling) was higher (P ≤ 0.05) in FP- cows than in FP+ cows. Regardless of group, cows with histopathologic evidence of endometritis had higher expression (P ≤ 0.05) of IL1α, IL1β, IL6, and TNFα than cows without endometritis. In conclusion, suppression of early ovulation by transvaginal FP enhances clearance of uterine inflammation in postpartum cows. PMID:25841545

  1. Risk groups in pathologic stage III endometrial carcinoma

    Purpose: Pathologic stage III (pIII) endometrial carcinoma is a heterogeneous group ranging from patients (pts) with positive washings alone to those with involved lymph nodes and multiple extra-uterine disease sites. Patients are traditionally grouped into two subsets (A and C). This approach, however, may fail to differentiate between pt groups with markedly different prognoses. Our goal was to stratify pIII pts into prognostic groups based on sites of extrauterine disease and pathologic features in the surgical specimen. Methods/Materials: Seventy-six pIII (46 IIIA, 30 IIIC) endometrial carcinoma pts were treated between (6(80)) and (6(95)). Median age was 65 years (range, 25-83). Stage IIIA subsets included isolated washings, serosal or adnexal involvement in 14, 11 and 11 pts, respectively. Ten had multiple extrau-terine sites without nodal involvement. Most tumors were adenocarcinomas (ACA) (59%), were grades II-III (87%) and had deep myometrial invasion (71%). Patients underwent TAH-BSO with lymph node sampling (in 79%) and evaluation of washings (in 78%). Sixty-one (79%) received radiation therapy (RT), predominantly pelvic +/- para-aortic/intracavitary RT. Chemo- and hormonal therapy were given in 22% and 21%, respectively. After first stratifying pts into 3 prognostic groups (Low, Intermediate and High risk) based on sites of extrauterine disease (washings, adnexa, serosal involvement and lymph nodes), we evaluated the prognostic impact of pathologic features (grade, histology, cervical involvement, myometrial and lymphovascular invasion) within each risk group. Median followup (surviving pts) was 50 months (range, 5-157). Results: The 5-year actuarial disease-free (DFS) and cause-specific (CSS) survivals of the entire group were 49.1% and 62.3%, respectively. Low risk pts were identified to have either positive washings alone or adnexal involvement alone. Intermediate risk pts had either serosal involvement alone or synchronous positive washings and

  2. Uterine sarcomas-Recent progress and future challenges

    Seddon, Beatrice M., E-mail: beatrice.seddon@uclh.nhs.uk [London Sarcoma Service, Department of Oncology, University College Hospital, 1st Floor Central, 250 Euston Road, London, NW1 2PG (United Kingdom); Davda, Reena [London Sarcoma Service, Department of Oncology, University College Hospital, 1st Floor Central, 250 Euston Road, London, NW1 2PG (United Kingdom)

    Uterine sarcomas are a group of rare tumours that provide considerable challenges in their treatment. Radiological diagnosis prior to hysterectomy is difficult, with the diagnosis frequently made post-operatively. Current staging systems have been unsatisfactory, although a new FIGO staging system specifically for uterine sarcomas has now been introduced, and may allow better grouping of patients according to expected prognosis. While the mainstay of treatment of early disease is a total abdominal hysterectomy, it is less clear whether routine oophorectomy or lymphadenectomy is necessary. Adjuvant pelvic radiotherapy may improve local tumour control in high risk patients, but is not associated with an overall survival benefit. Similarly there is no good evidence for the routine use of adjuvant chemotherapy. For advanced leiomyosarcoma, newer chemotherapy agents including gemcitabine and docetaxel, and trabectedin, offer some promise, while hormonal therapies appear to be more useful in endometrial stromal sarcoma. Novel targeted agents are now being introduced for sarcomas, and uterine sarcomas, and show some indications of activity. Non-pharmacological treatments, including surgical metastatectomy, radiofrequency ablation, and CyberKnife radiotherapy, are important additions to systemic therapy for advanced metastatic disease.

  3. Naproxen sodium decreases prostaglandins secretion from cultured human endometrial stromal cells modulating metabolizing enzymes mRNA expression.

    2016-04-01

    Dysmenorrhea, defined as painful cramps occurring immediately before or during the menstrual period, is a common symptom of different gynecological diseases. An acute uterine inflammatory response driven by prostaglandins (PGs) is responsible for painful symptoms. Progesterone withdrawal is responsible for activation of cyclooxygenase (COX-2) enzyme and decrease of hydroxyprostaglandin dehydrogenase (HPDG) with consequent increased secretion of PGs secretion, inducing uterine contractility and pain. The most widely used drugs for the treatment of pelvic pain associated with menstrual cycle are non steroidal anti-inflammatory drugs (NSAIDs). The uterine site of action of these drugs is still not defined and the present study evaluated the effect of naproxen sodium in cultured human endometrial stromal cells (HESC) collected from healthy women. PGE2 release was measured by ELISA; COX-2 and HPDG mRNA expression were assessed by qRT-PCR. Naproxen sodium did not affect HESC vitality. Naproxen sodium significantly decreased PGE2 secretion (p dysmenorrhea. PMID:26634864

  4. Association Between Single Nucleotide Polymorphism +276G > T (rs1501299) in ADIPOQ and Endometrial Cancer.

    2016-01-01

    Current literature gives evidence of an indisputable role adiponectin plays in adipose tissue metabolism and obesity-related diseases. Moreover, latest research efforts focus on linking genetic markers of this adipocytokine's gene (ADIPOQ) with cancer. Aim of this study was to determine the genotype distribution of single nucleotide polymorphism +276G > T (rs1501299) in ADIPOQ and an attempt to identify the impact this polymorphism exerts on endometrial cancer risk in obese females. The test group comprised 90 women treated surgically for endometrial cancer between 2000 and 2012 in the Department of Surgical & Endoscopic Gynecology and Gynecologic Oncology, Polish Mothers' Memorial Hospital - Research Institute, Lodz, Poland. 90 individuals treated in the parallel period for uterine fibroids constituted the control group. Patients within both groups were stratified according to BMI into: lean, overweight and obese subjects. Statistical analysis was performed between two major groups and, furthermore, within the abovementioned subgroups. The analysis revealed that allele G of the investigated polymorphism in obese women with endometrial cancer is significantly more frequent, and allele T is significantly less frequent than in lean controls. However, no significant correlation was observed between the polymorphism and endometrial cancer in lean and overweight females. Single nucleotide polymorphism +276G > T (rs1501299) in ADIPOQ may be considered to be a risk factor of endometrial cancer. Further research on SNP in EC is warranted to obtain more conclusive outcomes. PMID:26386690

  6. Microarray Analysis on Gene Regulation by Estrogen, Progesterone and Tamoxifen in Human Endometrial Stromal Cells

    Chun-E Ren

    2015-03-01

    Full Text Available Epithelial stromal cells represent a major cellular component of human uterine endometrium that is subject to tight hormonal regulation. Through cell-cell contacts and/or paracrine mechanisms, stromal cells play a significant role in the malignant transformation of epithelial cells. We isolated stromal cells from normal human endometrium and investigated the morphological and transcriptional changes induced by estrogen, progesterone and tamoxifen. We demonstrated that stromal cells express appreciable levels of estrogen and progesterone receptors and undergo different morphological changes upon hormonal stimulation. Microarray analysis indicated that both estrogen and progesterone induced dramatic alterations in a variety of genes associated with cell structure, transcription, cell cycle, and signaling. However, divergent patterns of changes, and in some genes opposite effects, were observed for the two hormones. A large number of genes are identified as novel targets for hormonal regulation. These hormone-responsive genes may be involved in normal uterine function and the development of endometrial malignancies.

  7. Quantitative light microscopic autoradiographic study on [3H]leukotriene C4 binding to nonpregnant bovine uterine tissue

    Mammalian uteri contain both lipoxygenase and cyclooxygenase pathways of arachidonic acid metabolism. Sulfidopeptidyl leukotrienes formed by the lipoxygenase pathway can stimulate uterine contractions and play a role in uterine preparation for implantation. These actions of leukotrienes are perhaps mediated by binding to specific receptors. To understand the cellular basis of leukotriene C4 action, the present quantitative light microscopic autoradiographic study was undertaken on nonpregnant bovine uterine tissue. The results demonstrated that the circular and elongated myometrial smooth muscle, uterine vascular smooth muscle, stromal cells of endometrium, and fibroblasts of perimetrium, but not the endometrial glands, vascular endothelium, and erythrocytes in lumen of arterioles, contained specific silver grains after incubation with [3H]leukotriene C4. The number of grains per 100-micron2 areas were similar in circular and elongated myometrial smooth muscle (P greater than 0.05), which was higher than in other uterine cells (P less than 0.05-0.01). The grains in all cells were greatly reduced after coincubation with excess unlabeled leukotriene C4, but not with leukotriene A4, leukotriene B4, leukotriene D4, leukotriene E4, prostaglandin E2, prostaglandin F2 alpha, or prostacyclin. In conclusion, leukotriene C4 may regulate both uterine cells and uterine vasculature and exert contractile and noncontractile actions via the specific leukotriene C4-binding sites present in different cell types

    Full Text Available Objective To observe the effect of anti-adhesion membrane made of oxidized regenerated cellulose (Interceed on endometrial receptivity in New Zealand white rabbits with intrauterine adhesion (IUA. Methods Forty-eight female rabbits were randomly divided into 4 groups (12 each: normal control group (group A, Interceed control group (group B, untreated model group (group C, and Inte rceed therapy group (group D. Rabbits in group A received sham operation and underwent no modeling. The Interceed was placed into the normal rabbits' uteruses in group B. The IUA rabbit models were reproduced in group C and group D by both mechanical injury and infection. Rabbits in group C were not treated, and in group D Interceed was put into their uteruses 7 days after modeling. Four rabbits in each group were sacrificed on the 28th day, the uterine tissues were collected. The endometrial glands count was performed after HE staining, and the degree of endometrial fibrosis was assessed after Masson staining. For the remaining animals in each group, ovulation was induced by stimulating the vagina in estrus, and they were sacrificed and the uterine tissue was collected on the 7th day after pseudopregnancy. The expression of pinopodes in endometrium was observed by scanning electron microscopy, and that of integrin αvβ3 protein was determined by immunohistochemistry. Results The expression of glands and the degree of fibrosis in endometrium was obviously improved in group D as compared with that of group C (P<0.05, but no significant difference was found among the groups A, B and D. In group A, and developed pinopodes were abundantly expressed in endometrial surface, and similar changes were found in group B. The expression of pinopodes in group C was scarce, and the development was not synchronized. More pinopodes, with irregular shape and synchronized development, were expressed in group D than in group C. The expression of integrin αvβ3 protein was

    Persistent endometritis in the mare is associated with hypersecretion of mucus by endometrial epithelium and migration of neutrophils into the uterine lumen. This study examines the relationships between N-acetylcysteine (NAC), a mucolytic agent with anti-inflammatory properties, and endometrial architecture, serum neutrophil function, post-breeding therapy, and reproductive performance of NAC-treated mares in a clinical setting. In study 1, endometrial biopsies from mares receiving intrauterine saline (fertile-control, n = 6) or 3.3% NAC (fertile-treatment, n = 6; barren-treatment, n = 10) were evaluated by histology and image analysis. In study 2, phagocytic activity of serum-derived neutrophils was measured after adding 0.5% or 3% NAC. In study 3, pregnancy rates of repeat breeders (n = 44) receiving an intrauterine infusion of 3.3% NAC 24-36 hours before mating (group 1) was recorded, as was first cycle of the season pregnancy rates of reproductively normal mares (group 2, n = 85), and mares treated for bacterial endometritis the cycle before mating (group 3, n = 25). Intrauterine NAC did not adversely affect endometrial histology. Extracellular mucus thickness and staining intensity were reduced in fertile-treatment mares (P NAC solution, but not by 0.5% NAC (P NAC was not irritating and inhibited the oxidative burst of neutrophils. Repeat breeder mares, with evidence of mucus hypersecretion, but no uterine pathogens, when treated with NAC followed by post-mating uterine lavage and oxytocin (and in some cases intrauterine antibiotics), achieved a pregnancy rate of 77%.

  15. Mesonephric Adenocarcinoma of the Uterine Corpus: A Case Report and Diagnostic Pitfall.

    Kim, Sung Sun; Nam, Jong Hee; Kim, Ga-Eon; Choi, Yoo Duk; Choi, Chan; Park, Chang Soo

    2016-04-01

    Mesonephric adenocarcinoma is a rare tumor type that is usually found in areas where the Wolffian duct was present during the fetal period. We report a case of mesonephric adenocarcinoma of the uterine corpus in a 66-year-old woman who presented with vaginal bleeding. Pelvic magnetic resonance imaging revealed a 2.7-cm-sized irregular thickening and enhancement of the uterine body. The diagnosis following endometrial curettage biopsy was endometrioid adenocarcinoma, and the patient underwent a total hysterectomy with bilateral salpingo-oophorectomy. The tumor was composed of small tubular and ductal components, and a retiform appearance was also observed in the deeper areas. The tumor cells were immunopositive for cytokeratin, vimentin, CD10 with a luminal staining pattern, PAX2, and PAX8, and immunonegative for estrogen receptor and progesterone receptor, which was consistent with tumor of mesonephric origin. Mesonephric neoplasms reveal relatively low-grade nuclear feature, characteristic immunoprofiles (immunonegative for ER and PR, and immunopositive for CD10, PAX2, PAX8, and GATA3), and unique tumor location (myometrium), whereas Müllerian neoplasms such as endometrial adenocarcinoma show various morphology, immunopositivity for ER and PR, and primarily endometrial location. As described above, an integration of the clinical features, morphologic characteristics, and immunohistochemical profiles is needed to make a diagnosis. PMID:26510860

  16. Endometrial aspiration cytology in gynecological disorders

    2016-01-01

    Full Text Available Context: Endometrial aspiration is not a popular modality for the study of the endometrium despite its simplicity and potential utility. Aim: The present study was aimed at evaluating the utility of endometrial aspiration in various gynecological disorders. Materials and Methods: In this diagnostic accuracy study, 55 prospectively registered women with various gynecological disorders were evaluated clinically and subjected to endometrial aspiration cytology and study of endometrial histology. Endometrial aspiration was performed by infant feeding tube in 10 cases and intra cath cannula in 45 cases. The slides were stained with rapid Papanicolaou (PAP stain and Leishman stain. Results: Endometrial aspiration cytology showed 90% and 94.6% sampling adequacy with infant feeding tube and intra cath cannula, respectively. Intra cath cannula was very convenient to handle and superior to infant feeding tube in aspirating the endometrium. Of the two stains used, rapid PAP stain was less time-consuming and superior to Leishman stain in studying the nuclear details. Leishman stain was helpful in detecting cytoplasmic vacuoles of secretory endometrium. Overall diagnostic accuracy of endometrial cytology was 90.4% while that for morphological hormonal evaluation was 97.6%. It enjoyed a sensitivity of 91.66%, a specificity of 88.23%, positive predictive value of 94.28%, and negative predictive value of 83.33%. Conclusion: Intra cath cannula emerged as an inexpensive, effective, and convenient device for endometrial aspiration. Endometrial aspiration proved to be a fairly effective, simple, and informative diagnostic modality.

  17. Endometrial biopsy findings in postmenopausal bleeding

    To study endometrial histopathology in women presenting with postmenopausal bleeding. A two-year study from January 2003 to December 2004 of 100 cases of postmenopausal bleeding was conducted at Combined Military Hospital, Sialkot. The histopathology of endometrial biopsy specimens was done to find out the causes of postmenopausal bleeding in these ladies. All these 100 patients had confirmed menopause and the average age was 55 years and above. The most common histopathological diagnosis was senile endometrial atrophy (27%), followed by simple cystic hyperplasia in (17%). Three cases of simple cystic hyperplasia had coexistent ovarian tumors. Glandular hyperplasia without atypia was seen in 6% and with atypia in 4%. Other causes were endometritis (13%), endometrial polyps (8%), proliferative phase endometrium (6%) and secretary phase endometrium (5%). Endometrial carcinoma was seen in (6%) cases, (8%) biopsy specimens were non-representative. Although senile endometrial atrophy was most commonly found in these ladies but a significant percentage of endometrial hyperplasia and endometrial cancer implies the need for investigating all cases of postmenopausal bleeding. Bimanual examination and pelvic ultrasonography should be combined with endometrial sampling so that rare pelvic pathologies may not be missed. (author)

  19. Persisting cyclical uterine bleeding in patients treated with radical radiation therapy and hormonal replacement for carcinoma of the cervix

    Radical radiation therapy used for carcinoma of the cervix will ablate ovarian function. Since January 1986, our policy has been to administer oral combination oestrogen-progesterone replacement hormonal therapy to all premenopausal patients undergoing radical radiation with or without synchronous chemotherapy, for invasive cervix cancer. Five out of 22 (23%) such patients unexpectedly experienced between one and four episodes of cyclical per vaginal bleeding after the completion of radiation therapy. Bleeding episodes occurred in the absence of persistent tumor or radiation reaction, and suggest persisting endometrial response to exogenous hormonal stimulation. Uterine activity was temporarily retained in these five patients despite a minimal endometrial surface dose of between 4800 and 6490 cGy. The limited number of cycles before bleeding spontaneously ceased may represent the slow death of endometrial cells subsequent to radiation or radiochemotherapy treatment, and has not previously been described. In view of the paucity of data on the radiosensitivity of normal endometrium, we have carefully examined these patients who appear to have retained endometrial sensitivity to hormonal stimuli after radical radiation-chemotherapy for uterine cervix cancer

    2014-01-01

    Carcinogenesis is a multistage process, during which the activity of signalling pathways responsible for cell cycle regulation and division is disrupted which leads to inhibition of apoptosis and enhanced proliferation. Improper activation of Wnt/β-catenin and PI3K. Akt pathways play essential role in endometrial cancers (EC), mainly type I. Mutations in APC, axin or CTNBB1 may lead to β-catenin overactivation leading to excessive gene expression. PTEN inactivation, mutations in the PIK3CA or...

    Human implantation is a complex process requiring synchrony between a healthy embryo and a functionally competent or receptive endometrium. Diagnosis of endometrial receptivity (ER) has posed a challenge and so far most available tests have been subjective and lack accuracy and a predictive value. Microarray technology has allowed identification of the transcriptomic signature of the window of receptivity window of implantation (WOI). This technology has led to the development of a molecular ...

    Full Text Available Problem statement: Hysteroscopy is a procedure in which the endometrial cavity is observable and subject of manipulation via transcervical route. Hysteroscopy is a minimally invasive process in diagnosis and treatment of many intrauterine and endocervical conditions. Polypectomy, myomectomy and endometrial ablation could be easily manageable by this procedure. According to safety and high efficiency of hysteroscopy, this method is changing to a widespread procedure in dealing with many gynecologic and obstetrical conditions. This study aimed at evaluating the diagnostic and therapeutical efficiency of hysteroscopy in managing of common conditions including abnormal uterine bleeding and abortion. Approach: In a descriptive cross-sectional setting, 243 women underwent hysteroscopy were evaluated in two groups: with uterine bleeding 236 cases and with recurrent abortions 7 cases. This study was conducted in Tabriz Alzahra Educational Center during a 15-month period. The main causes of the complaints were determined in each group. Six months after treatment, the overall success rate was recorded. Results: Hysteroscopy was the sole diagnostic procedure in 16.5 and 14.3% of the patients in groups with abnormal uterine bleeding and abortion, respectively. In the group with abnormal uterine bleeding, curettage, myomectomy, polypectomy, hysterectomy, laparoscopy and laparotomy were the main diagnostic-therapeutical approaches along with the hysteroscopy in descending order. In the group with recurrent abortion, laparoscopy, curettage and myomectomy were the main diagnostic-therapeutical approaches along with the hysteroscopy in descending. There was not any major complication. The diagnostic-therapeutical measures accompanying with the laparoscopy were successful in 73.5% of the bleeding group in follow-up period. Conclusion: Based on our results, hysteroscopy is a safe, accurate and highly-efficient procedure in managing women with abnormal uterine

    The effects of pregnancy and undernutrition on endometrial gene expression were investigated in ewes fed all or half their maintenance requirements and killed on Day 14 of pregnancy or of the oestrous cycle. The endometrial expression of progesterone, oestrogen, oxytocin and interferon receptors (PR, ERalpha, OXTR and IFNAR, respectively), cyclo-oxygenase (COX)-2, proliferating cell nuclear antigen (PCNA), insulin-like growth factors (IGF)-I and -II, and IGF-1 receptor (IGF-1R) was studied by immunohistochemistry or real-time reverse transcription-polymerase chain reaction. The luminal epithelium of cyclic control ewes was devoid of PR staining and had relatively high levels of ERalpha, OXTR, COX-2 and IFNAR2. The presence of a conceptus decreased the in vitro uterine secretion of prostaglandin (PG) F(2alpha) and the expression of IFNAR2 in most cell types, and increased the gene expression of IGF-I and IGF-II. Undernutrition tended to increase ERalpha protein and gene, but decreased in vitro uterine secretion of PGE(2) and the gene expression of IFNAR2 in cyclic ewes. There was no effect of undernutrition on pregnancy rates or the number of conceptuses recovered. Consistent with this, undernutrition of pregnant ewes did not have any effect on uterine gene expression. Moreover, in cases where changes were observed in cyclic ewes, these changes were negated when a conceptus was present. PMID:19698291

    Leiomyomas and other mesenchymally derived tumors are the most common neoplasms of the female reproductive tract. Presently, very little is known about the etiology and progression of these tumors, which are the primary indication for hysterectomies. Dysregulated WNT signaling through beta-catenin is a well-established mechanism for tumorigenesis. We have developed a mouse model that expresses constitutively activated beta-catenin in uterine mesenchyme driven by the expression of Cre recombinase knocked into the Müllerian-inhibiting substance type II receptor promoter locus to investigate its effects on uterine endometrial stroma and myometrium. These mice show myometrial hyperplasia and develop mesenchymal tumors with 100% penetrance that exhibit histological and molecular characteristics of human leiomyomas and endometrial stromal sarcomas. By immunohistochemistry, we also show that both transforming growth factor beta and the mammalian target of rapamycin are induced by constitutive activation of beta-catenin. The prevalence of the tumors was greater in multiparous mice, suggesting that their development may be a hormonally driven process or that changes in uterine morphology during pregnancy and after parturition induce injury and repair mechanisms that stimulate tumorigenesis from stem/progenitor cells, which normally do not express constitutively activated beta-catenin. Additionally, adenomyosis and endometrial gland hyperplasia were occasionally observed in some mice. These results show evidence suggesting that dysregulated, stromal, and myometrial WNT/beta-catenin signaling has pleiotropic effects on uterine function and tumorigenesis. PMID:19403928

  8. Patterns of bone morphogenetic protein-2 expression in smooth muscle tumors of the uterine corpus and other uterine tissues.

    2011-07-01

    Bone morphogenetic proteins (BMPs) are extracellular, multifunctional growth factors that constitute the largest subset of the transforming growth factor β superfamily. BMP2 is involved in cardiovascular embryogenesis, in addition to a variety of other postnatal functions, such as neovascularization, osteoinduction, tumor signaling, and in the uterus, stromal decidualization at the implantation site. Estrogen receptor signaling is common in smooth muscle tumors of the uterus, and preclinical models suggest significant interactions between BMP2 and estrogen receptor-mediated signaling. The purpose of this study is to define the patterns of BMP2 expression, as assessed by immunohistochemistry, in smooth muscle tumors and other tissues of the uterine corpus, and to establish whether BMP2 expression has any prognostic significance in uterine leiomyosarcomas. BMP2 was positive (cytoplasmic pattern, typically focal) in 24% of leiomyosarcomas and 20.7% of leiomyomata, but was either infrequently expressed or not expressed in all other tissues evaluated, including normal myometrium and endometrium, endometrial stromal tumors, typical adenomyoma, adenomyosis, and serosal endometriosis. The endothelial cells of small, thin-walled vessels were frequently, but not invariably immunoreactive for BMP2. There was no significant difference between BMP2⁺ and BMP⁻ leiomyosarcomas regarding average tumor size, average patient age, microvessel density, and proportions with high tumor grade, advanced stage and frequency of death from disease on follow-up. Two (29%) of 7 BMP2⁺ leiomyosarcomas were estrogen receptor+, compared with 5 (50%) of 10 BMP2⁻ leiomyosarcomas, a statistically insignificant difference (P=0.62). It is concluded that BMP2 is only expressed in a minority of smooth muscle tumors of the uterine corpus, and lacks prognostic significance in leiomyosarcomas. BMP2 is rarely expressed in the other nonendothelial tissues of the human uterine corpus that were

  9. Two different embolic agents in the treatment of uterine arterial embolization for symptomatic fibroids

    Objective: To compare the efficacy and safety of dextran microspheres and polyvinyl alcohol particles in the uterine arterial embolization (UAE)for symptomatic uterine leiomyomata. Methods: Forty women (mean aged 38.5 years, ranged 28-44 years)with symptomatic myomas were randomly divided into two groups with 20 patients in each, PVA (polyvinyl alcohol particles, 355-500 μm)was used as embolic agents in group A and dextran microspheres(Sephadex G-50, 100-300 μm)in group B. The mean diameter of fibroids was 6.5 cm (range, 3-12 cm)with symptoms of menorrahgia, bulk-related symptoms, dysmenorrhea and infertility. Analgesics, anti-infection and rehydration treatments were used after the procedure. The hospital stay, post-embolization syndromes, follow-up materials were reviewed and compared. Results: The hospital stay and the post embolization pain showed no obvious difference between the two groups, simultaneously with no serious complications. The average follow-up duration was 9 months (range, 6-24 months). The average volumes of uterus and fibroid in group A and B decreased gradually during follow-up: 53.4%, 55% and 48.6%, 40.9%, respectively. Conclusion: Dextran microspheres is as the same effective and safe as PVA particles for UAE, but rather cheaper than latter. Further prospective study is warranted. (authors)

    Full Text Available ABSTRACT: INTRODUCTION: Abnormal uterine bleeding is a common complai nt for which many patients in the perimenopausal age group un dergo hysterectomy. The objective of this study is to analyze the causes of AU B in subjects who had hysterectomy. MATERIAL AND METHODS: The pathological specimens from 100 patients who had hysterectomy for AUB between January 2012 and January 2013 we re studied based on the gross and microscopic appearance. RESULTS: Leiomyoma alone was the most common cause of AUB (54% in patients who had hysterectomy. Leiomy oma was associated with adenomyosis in 20% cases and adenomyosis alone was seen in 10%. Endometrial cancer was found in 2% of patients. CONCLUSION: Leiomyoma is the most common indication for hysterectomy in women with AUB between 40 and 50 years. It may occur alone or may be associated with conditions like adenomyosis or endometria l polyps

    Successful implantation occurred after embryo transfer in the presence of an extensive endometrial defect after hysteroscopic resection of residual trophoblastic tissue 15 months after cesarean section. At the end of hysteroscopic surgery the anterior uterine wall seemed smooth, although ultimately no endometrium was left in that part and in parts of the fundus. Thus implantation is possible even with extensive endometrial defects. Interesting facts in this case were, first, the long symptom-free period with residual trophoblastic tissue in the uterus, and, second, successful implantation, pregnancy, and delivery despite at least 30% of endometrial surface being irreversibly destroyed. We suggest hysteroscopic resection as the method of choice for exact and minimally traumatic removal of especially older residual trophoblastic tissue. PMID:12386371

  12. Diagnosis and Management of Endometrial Cancer.

    2016-03-15

    Endometrial cancer is the most common gynecologic malignancy. It is the fourth most common cancer in women in the United States after breast, lung, and colorectal cancers. Risk factors are related to excessive unopposed exposure of the endometrium to estrogen, including unopposed estrogen therapy, early menarche, late menopause, tamoxifen therapy, nulliparity, infertility or failure to ovulate, and polycystic ovary syndrome. Additional risk factors are increasing age, obesity, hypertension, diabetes mellitus, and hereditary nonpolyposis colorectal cancer. The most common presentation for endometrial cancer is postmenopausal bleeding. The American Cancer Society recommends that all women older than 65 years be informed of the risks and symptoms of endometrial cancer and advised to seek evaluation if symptoms occur. There is no evidence to support endometrial cancer screening in asymptomatic women. Evaluation of a patient with suspected disease should include a pregnancy test in women of childbearing age, complete blood count, and prothrombin time and partial thromboplastin time if bleeding is heavy. Most guidelines recommend either transvaginal ultrasonography or endometrial biopsy as the initial study. The mainstay of treatment for endometrial cancer is total hysterectomy with bilateral salpingo-oophorectomy. Radiation and chemotherapy can also play a role in treatment. Low- to medium-risk endometrial hyperplasia can be treated with nonsurgical options. Survival is generally defined by the stage of the disease and histology, with most patients at stage I and II having a favorable prognosis. Controlling risk factors such as obesity, diabetes, and hypertension could play a role in the prevention of endometrial cancer. PMID:26977831

  14. COUP-TFII mediates progesterone regulation of uterine implantation by controlling ER activity.

    Isao Kurihara

    2007-06-01

    Full Text Available Progesterone and estrogen are critical regulators of uterine receptivity. To facilitate uterine remodeling for embryo attachment, estrogen activity in the uterine epithelia is attenuated by progesterone; however, the molecular mechanism by which this occurs is poorly defined. COUP-TFII (chicken ovalbumin upstream promoter transcription factor II; also known as NR2F2, a member of the nuclear receptor superfamily, is highly expressed in the uterine stroma and its expression is regulated by the progesterone-Indian hedgehog-Patched signaling axis that emanates from the epithelium. To further assess COUP-TFII uterine function, a conditional COUP-TFII knockout mouse was generated. This mutant mouse is infertile due to implantation failure, in which both embryo attachment and uterine decidualization are impaired. Using this animal model, we have identified a novel genetic pathway in which BMP2 lies downstream of COUP-TFII. Epithelial progesterone-induced Indian hedgehog regulates stromal COUP-TFII, which in turn controls BMP2 to allow decidualization to manifest in vivo. Interestingly, enhanced epithelial estrogen activity, which impedes maturation of the receptive uterus, was clearly observed in the absence of stromal-derived COUP-TFII. This finding is consistent with the notion that progesterone exerts its control of implantation through uterine epithelial-stromal cross-talk and reveals that stromal-derived COUP-TFII is an essential mediator of this complex cross-communication pathway. This finding also provides a new signaling paradigm for steroid hormone regulation in female reproductive biology, with attendant implications for furthering our understanding of the molecular mechanisms that underlie dysregulation of hormonal signaling in such human reproductive disorders as endometriosis and endometrial cancer.

    Endometrial cancer represents the most frequent gynecological malignant affection in the developed countries, in which the incidence of cervical cancer has significantly decreased due to the rigorous application of screening methods and prophylaxis. According to its frequency, endometrial cancer is situated on the fourth place in the category of women's genital-mammary malignant diseases, after breast, cervical and ovarian cancer in Romania. The incidence and mortality rates due to endometrial cancer have registered an increasing trend worldwide and also in Romania, a significant decrease of the age of appearance for the entire endometrial pathology sphere being noticed. At the national level, the maximum incidence is situated between 60 and 64 years old, the mortality rate of the women under 65 years old being high in Romania. The study evaluates endometrial cancer, from an epidemiologic point of view, at the national level compared to the international statistic data. PMID:25866582

    2005-01-01

    Objective: To study the clinical pathological characteristics of ovarian metastasis of endometrial carcinoma and the factors affecting prognosis. Methods: Retrospective analysis was made to the clinical pathological outcome of endometrial carcinoma patients receiving surgical treatment in our hospital from January 1990 to December 2002. Results:Among the 191 cases of endometrial carcinoma patients, 17 cases (8.9%) had ovarian metastasis and young patients were more likely to have ovarian metastasis. The multiple factor analysis showed that the independent risk factors of ovarian metastasis in endometrial carcinoma included the depth of myometrial invasion, lymph node metastasis and pathological types. Conclusion: Ovarian metastasis in patients with endometrial carcinoma is associated with poor prognosis, the depth of myometrial invasion, lymph node metastasis and histologic types are independent risk factors affecting the prognosis. For young patients at early stage of the disease, it should be prudent as to whether to retain the ovary.

  18. Chorionic gonadotropin and uterine dialogue in the primate

    Strakova Zuzana

    2004-07-01

    Full Text Available Abstract Implantation is a complex spatio-temporal interaction between the growing embryo and the mother, where both players need to be highly synchronized to be able to establish an effective communication to ensure a successful pregnancy. Using our in vivo baboon model we have shown that Chorionic Gonadotropin (CG, as the major trophoblast derived signal, not only rescues the corpus luteum but also modulates the uterine environment in preparation for implantation. This response is characterized by an alteration in both the morphological and biochemical activity in the three major cell types: luminal and glandular epithelium and stromal fibroblasts. Furthermore, CG and factors from the ovary have a synergistic effect on the receptive endometrium. Novel local effects of CG which influence the immune system to permit the survival of the fetal allograft and prevent endometrial cell death are also discussed in this review. An alternate extracellular signal-regulated kinase (ERK activation pathway observed in epithelial endometrial cells and the possibility of differential expression of the CG/LH-R isoforms during gestation, open many questions regarding the mechanism of action of CG and its signal transduction pathway within the primate endometrium.

    The purpose of this study was to define guidelines for endometrial cancer staging with MRI. The technique included critical review and expert consensus of MRI protocols by the female imaging subcommittee of the European Society of Urogenital Radiology, from ten European institutions, and published literature between 1999 and 2008. The results indicated that high field MRI should include at least two T2-weighted sequences in sagittal, axial oblique or coronal oblique orientation (short and long axis of the uterine body) of the pelvic content. High-resolution post-contrast images acquired at 2 min {+-} 30 s after intravenous contrast injection are suggested to be optimal for the diagnosis of myometrial invasion. If cervical invasion is suspected, additional slice orientation perpendicular to the axis of the endocervical channel is recommended. Due to the limited sensitivity of MRI to detect lymph node metastasis without lymph node-specific contrast agents, retroperitoneal lymph node screening with pre-contrast sequences up to the level of the kidneys is optional. The likelihood of lymph node invasion and the need for staging lymphadenectomy are also indicated by high-grade histology at endometrial tissue sampling and by deep myometrial or cervical invasion detected by MRI. In conclusion, expert consensus and literature review lead to an optimized MRI protocol to stage endometrial cancer. (orig.)

  20. Radical radiotherapy for endometrial cancer and clinical evaluation of radiation dose for reference points

    Fifteen patients with endometrial cancer (Stage I [5], Stage II [4], Stage III [4], Stage IVa [2]) were treated by radiation therapy alone at Tokyo Women's Medical College during the 23-year period from 1969 to 1991. All patients were considered medically inoperable due to advanced age, hypertension, cardiovascular disease, diabetes mellitus, etc. Patient ages ranged from 46 to 82 years with a mean of 63 years (62.5±12.0). An external beam with a 10 MeV linear accelerator and low dose-rate intracavitary radiotherapy using a TAO applicator were administered to the patients with a total dose of 87.2±19.5 Gy at point A for cervical cancer. The complete response rate was 66.7% by clinical examination after treatment. Intrapelvic recurrence was seen in 1 patient and distant metastasis in 3. The 5-year cumulative survival rate for all patients was 59.3% and 100% for Stage I and II, respectively. Rectal complications were found in 4 cases, bladder in 2. In order to standardize the dose value for radiotherapy for endometrial cancer, we established three reference points (point I: fundus of the uterus, point II: bilateral uterotubal ostium, point III: bilateral mid portion of the lateral wall of the uterine body). These points were determined by measuring myometrial thickness of the uterine body by CT image at the time of treatment planning in each case. We make practical application of these points in radiation treatment and have found them to be useful for standardization and dose specification of intracavitary radiotherapy for endometrial cancer.

  1. INFLUENCE OF NEOADJUVANT INTRAARTERIAL INFUSION CHEMOTHERAPY ON APOPTOSIS AND MULTIDRUG RESISTANCE ASSOCIATED GENES OF ENDOMETRIAL CANCER

    朱雪琼; 岳天孚; 张颖; 惠京; 王德华

    2002-01-01

    Objective: Through investigating the influence of neoadjuvant intraarterial infusion chemotherapy (NIAC) on the timing changes of apoptosis, PCNA and multiple drug resistance associated genes of endometrial cancer, to study the mechanism of chemotherapy and to define the best operation time. Methods: Twenty patients were subjected to neoadjuvant consecutive uterine arterial infusion with CDDP 100 mg and ADM 50 mg. The biopsy of endometrial tumor tissues was performed before, immediate after and 1, 2-2+3 w, 3+3-4 w after chemotherapy. Apoptosis index (AI) was estimated by a combination of histologic and TUNEL assays. Proliferative index (PI) was examined by SABC immunohistochemical staining. Expressions of multidrug resistance 1 (MDR1), multidrug resistance-associated protein (MRP) and lung resistance protein (LRP) were detected by reverse transcription polymerase chain reaction (RT-PCR). Results: The AI of endometrial cancer cells immediate after and 1, 2-2+3 w, after chemotherapy were 3.03%, 3.47% and 5.04%, respectively, much higher than that before chemotherapy which was 2.31%. After chemotherapy, AI/PI gradually increased. It was highest in 2-2+3 w, while 3+3-4 w after chemotherapy the AI and AI/PI were both significantly lower than that before chemotherapy. The expression of MDR1, MRP and LRP all decreased temporarily after chemotherapy, while 3+3-4 w after chemotherapy they all increased to levels higher than that before chemotherapy, but the difference were not significant (P>0.05). Conclusion: Neoadjuvant consecutive intra-arterial infusion chemotherapy via uterine artery can inhibit tumor cells proliferation and induce apoptosis effectively. To evaluate the response of intra-arterial chemotherapy the change of apoptosis index and cell proliferation should be analyzed. The most suitable time for the operation is 3 weeks after intra-arterial infusion chemotherapy.

  2. Ultrasonographic findings of uterine polypoid adenomyomas

    To characterize the ultrasonographic findings of polypoid adenomyoma of the uterus. Ultrasonographic findings of twenty seven patients with histologically confirmed polypoid adenomyoma were retrospectively reviewed. Ultrasonography (US) was performed in all patients while sonohysterography (SH) in fifteen patients and color Doppler sonography (CDS) in thirteen patients were additionally performed. Location, size, growth pattern, surface, margin from the endometrim and underlying myometrium, echogenecity and echotexture, presence and patterns of cystic areas, hemorrhage, and posterior shadowing of the endometrial or submucosal mass on US and SH were evaluated. The presence of blood flow and resistive index (RI) on CDS were also evaluated. On US and SH, the tumor location was the corpus in sixteen cases, fundus in eight, and isthmus in three cases, and the tumor size ranged from 0.5 to 6 cm (mean 3.5 cm). The tumors were polypoid in eighteen cases, sessile in four cases, and pedunculated in five cases, and three of them protruded into endocervical canal while two cases prolapsed through externals os. The surface was smooth in twenty six cases, lobulated in four and irregular in one. Nineteen cases had ill defined margin while eight cases, a well circumscribed margin. The mass was inhomogeneously isoechoic in twelve cases, homogeneously isoechoic in seven cases, homogeneously and inhomogeneously hyperechoic in four cases each, respectively. Cystic areas were seen in twenty cases, and there were three patterns of cystic areas: all solid mass (pattern 1, n=7), solid mass with cystic areas (pattern 2, n=18) and predominantly cystic mass (pattern 3, n=2). Eight cases had hemorrhage and seven had posterior shadowing. CDS showed a blood flow with range of RI from 0.19 to 0.74 (mean 0.47). Other findings included adenomyosis in sixteen cases, leiomyoma in three, and endometrial thickening and mass in one each, respectively. Polypoid adenomyoma can be characterized as a

The surface was smooth in twenty six cases, lobulated in four and irregular in one. Nineteen cases had ill defined margin while eight cases, a well circumscribed margin. The mass was inhomogeneously isoechoic in twelve cases, homogeneously isoechoic in seven cases, homogeneously and inhomogeneously hyperechoic in four cases each, respectively. Cystic areas were seen in twenty cases, and there were three patterns of cystic areas: all solid mass (pattern 1, n=7), solid mass with cystic areas (pattern 2, n=18) and predominantly cystic mass (pattern 3, n=2). Eight cases had hemorrhage and seven had posterior shadowing. CDS showed a blood flow with range of RI from 0.19 to 0.74 (mean 0.47). Other findings included adenomyosis in sixteen cases, leiomyoma in three, and endometrial thickening and mass in one each, respectively. Polypoid adenomyoma can be characterized as a

    The aim of this study was to investigate the effect of puerperal uterine disease on histopathologic findings and gene expression of proinflammatory cytokines in the endometrium of postpuerperal dairy cows; 49 lactating Holstein-Friesian cows were divided into two groups, one without (UD-; n = 29) and one with uterine disease (UD+; n = 21), defined as retained fetal membranes and/or clinical metritis. General clinical examination, vaginoscopy, transrectal palpation, and transrectal B-mode sonography were conducted on days 8, 11, 18, and 25 and then every 10 days until Day 65 (Day 0 = day of calving). The first endometrial sampling (ES1; swab and biopsy) was done during estrus around Day 42 and the second endometrial sampling (ES2) during the estrus after synchronization (cloprostenol between days 55 and 60 and GnRH 2 days later). The prevalence of histopathologic evidence of endometritis, according to the categories used here, and positive bacteriologic cultures was not affected by group (P > 0.05), but cows with uterine disease had a higher prevalence of chronic purulent endometritis (ES1; P = 0.07) and angiosclerosis (ES2; P ≤ 0.05) than healthy cows. Endometrial gene expression of IL1α (ES2), IL1β (ES2), and TNFα (ES1 and ES2) was higher (P ≤ 0.05) in the UD+ group than in the UD- group. In conclusion, puerperal uterine disease had an effect on histopathologic parameters and on gene expression of proinflammatory cytokines in the endometrium of postpuerperal cows, indicating impaired clearance of uterine inflammation in cows with puerperal uterine disease.

    Full Text Available Objective. Evaluate if different bleeding patterns associated with the use of the levonorgestrel intrauterine system (LNG-IUS are associated with different uterine and endometrial vascularization patterns, as evidenced by ultrasound power Doppler analysis. Methodology. A longitudinal study, with each subject acting as its own control was conducted between January 2010 and December 2012. Healthy volunteers with a history of heavy but cyclic and regular menstrual cycles were enrolled in the study. Ultrasonographic examination was performed before and after six months of LNG-IUS placement: uterine volume, endometrial thickness, and subendometrial and myometrial Doppler blood flow patterns have been evaluated. Results. A total of 32 women were enrolled out of 186 initially screened. At six months of follow-up, all subjects showed a reduction in menstrual blood loss; for analysis, they were retrospectively divided into 3 groups: normal cycling women (Group I, amenorrheic women (Group II, and women with prolonged bleedings (Group III. Intergroup analysis documented a statistically significant difference in endometrial thickness among the three groups; in addition, mean pulsatility index (PI and resistance index (RI in the spiral arteries were significantly lower in Group I and Group III compared to Group II. This difference persisted also when comparing—within subjects of Group III—mean PI and RI mean values before and after insertion. Conclusions. The LNG-IUS not only altered endometrial thickness, but—in women with prolonged bleedings—also significantly changed uterine artery blood flow. Further studies are needed to confirm these results and enable gynecologists to properly counsel women, improving initial continuation rates.

    Building a training system for medical personnel to properly interpret fetal heart rate tracing requires developing accurate models that can relate various signal patterns to certain pathologies. In addition to modeling the fetal heart rate signal itself, the change of uterine pressure that bears strong relation to fetal heart rate and provides indications of maternal and fetal status should also be considered. In this work, we have developed a group of parametric models to simulate uterine contractions during labor and delivery. Through analysis of real patient records, we propose to model uterine contraction signals by three major components: regular contractions, impulsive noise caused by fetal movements, and low amplitude noise invoked by maternal breathing and measuring apparatus. The regular contractions are modeled by an asymmetric generalized Gaussian function and least squares estimation is used to compute the parameter values of the asymmetric generalized Gaussian function based on uterine contractions of real patients. Regular contractions are detected based on thresholding and derivative analysis of uterine contractions. Impulsive noise caused by fetal movements and low amplitude noise by maternal breathing and measuring apparatus are modeled by rational polynomial functions and Perlin noise, respectively. Experiment results show the synthesized uterine contractions can mimic the real uterine contractions realistically, demonstrating the effectiveness of the proposed algorithm.

    Integrated positron emission tomography/computed tomography (PET/CT) with 2-[{sup 18}F]fluoro-2-deoxy-D-glucose (FDG) is a useful technique to acquire both glucose metabolic and anatomic imaging data using a single device in a single diagnostic session and has opened a new field in clinical oncologic imaging. FDG-PET/CT has been used successfully for the staging, optimization of treatment, re-staging, therapy monitoring, and prognostic prediction of uterine cervical cancer and endometrial cancer as well as various malignant tumours. The present review discusses the current role of FDG-PET/CT in the management of uterine cancer, discussing its usefulness and limitations in the imaging of these patients.

    Postpartum uterine inflammation (endometritis) in the dairy cow is associated with lower fertility at both the time of infection and after the inflammation has resolved. We hypothesized that aberrant DNA methylation may be involved in the subfertility associated with uterine inflammation. The objective of this study was to characterize genome-wide DNA methylation and gene expression in the endometrium of dairy cows with subclinical endometritis (SCE). Endometrial tissues were obtained at 29 days postpartum (n = 12), and microarrays were used to characterize transcription and DNA methylation. Analyses revealed 1,856 probes differentially expressed in animals with SCE (n = 6) compared with controls (CON, n = 6, P cows, with the majority related to the immune response. Furthermore, the top ontology terms enriched in genes that had expression data correlated to bacteriology score were: Defense response, inflammatory response, and innate immune response. Gene expression profiles in cows with subclinical endometritis in this study indicate that the immune response is activated, potentially resulting in a local proinflammatory environment in the uterus. If this period of inflammation is prolonged it could result in tissue damage or failure to complete involution of the uterus, which may create a suboptimal environment for future pregnancy.

  9. Radiological appearances of uterine fibroids

    Uterine fibroids, also known as leiomyomas, are the commonest uterine neoplasms. Although benign, they can be associated with significant morbidity and are the commonest indication for hysterectomy. They are often discovered incidentally when performing imaging for other reasons. Usually first identified with USG, they can be further characterized with MRI. They are usually easily recognizable, but degenerate fibroids can have unusual appearances. In this article, we describe the appearances of typical and atypical uterine fibroids, unusual fibroid variants and fibroid mimics on different imaging modalities. Knowledge of the different appearances of fibroids on imaging is important as it enables prompt diagnosis and thereby guides treatment

  10. MR staging of endometrial carcinoma

    Biopsy is the technique of choice for the definitive diagnosis of endometrial carcinoma. Since lymphatic tumor spread has been demonstrated to depend on the degree of myometrial involvement, the definition of the latter with imaging techniques may significantly affect both pfognosis and therapy. We investigated, by means of MR imaging at 0.5 T, 14 patients with endometrial carcinoma, to assess both tumor stage and myometrial involvement. FIGO staging system was employed, and M parameter evaluated (M0= no myometrial involvement; M1involvement confined to the inner third; M2= Involvement confined to the middle third; M3= involvement of the whole myometrium). Another parameter was the characteristic high signal of the tumor on PD and T2W images. The patients were then operated and MR information was correlated with surgical findings. Overall diagnostic accuracy of MR imaging was 85.7% in tumor staging, and 92.2% in defining M parameter. Tumor spread into adnexa and into cervical canal was poorly demonstrated by MR imaging

  13. Mucin 1 and cytokines mRNA in endometrium of dairy cows with postpartum uterine disease or repeat breeding.

    Kasimanickam, R; Kasimanickam, V; Kastelic, J P

    2014-04-15

    Mucin (MUC) 1 is an inducible innate immune effector, an important component of defense against bacterial invasion, and is linked with infertility in humans. The objectives were to evaluate messenger RNA (mRNA) expression of MUC1 and cytokine genes in the endometrium of cows with various postpartum uterine inflammatory conditions or with a history of repeat breeding. Endometrial samples were collected from lactating dairy cows diagnosed with metritis (n = 4), endometritis (n = 4), subclinical endometritis (n = 4), or no uterine pathology (normal; n = 4). In addition, endometrial samples were collected from repeat breeder cows with (n = 4) or without (n = 4) subclinical endometritis, and unaffected cows (n = 4). Quantitative polymerase chain reaction was used to determine mRNA abundances of MUC1, Toll-like receptor (TLR) 4, interleukin (IL) 1β, IL6, IL8, tumor necrosis factor (TNF) α, insulin-like growth factor (IGF) 1, and IGF-binding protein (BP) 2. The mRNA expressions were significantly greater for cows with metritis and clinical endometritis compared with cows with no uterine inflammation, except for IL6. However, mRNA expressions for these target genes were not different for cows with subclinical endometritis, compared with cows without uterine inflammation, except for IL1β and TNFα mRNA (P cows with subclinical endometritis compared with normal cows. However, in repeat breeder cows without subclinical endometritis, only expressions of MUC1, IGF1, and IGF BP2 were greater compared with normal cows (P cows. Perhaps, these altered gene expressions contribute to endometrial insufficiency and consequently pregnancy wastage. PMID:24576715

    Objective:To explore the clinical efficacy of small-dose mifepristone in combined with Gongxuening capsule in the treatment of perimenopasual dysfunctional uterine bleeding and their effects on sex hormone levels. Methods: The perimenopasual women with dysfunctional uterine bleeding who were admitted in our hospital from October, 2014 to October, 2015 and received small-dose mifepristone in combined with Gongxuening capsule were served as the observation group. They were orally administered with mifepristone, 6.25 mg/time, 1 time/d, taken before bedtime, and Gongxuening capsule, 2 pills/time, 3 times/d, for 7 d after each menstruation, and continuously for 3 months. The perimenopasual women with dysfunctional uterine bleeding who were received mifepristone were served as the control group. They were orally administered with mifepristone, 12.5 mg/time, 1 time/d, taken before bedtime, and continuously for 3 months. The HGB level and endometrial thickness before and after treatment were detected. The bleeding control time, total blood stopping time, and adverse reactions in the two groups were compared. The levels of FSH, E2, P, and LH before and after treatment in the two groups were determined. Results:After treatment, HGB level in the observation group was elevated, and the altered degree of endometrial thickness was significantly superior to that in the control group (P0.05). Conclusions: Small-dose mifepristone in combined with Gongxuening capsule in the treatment of perimenopasual dysfunctional uterine bleeding can effectively improve the endometrial thickness, timely control bleeding, and improve the serum sex hormone levels, with a satisfactory effect;therefore, it deserves to be widely recommended in the clinic.

    Hexachlorobenzene (HCB) is an organochlorine pesticide that induces toxic reproductive effects in laboratory animals. It is a dioxin-like compound and a weak ligand of the aryl hydrocarbon receptor (AhR). Endometriosis is characterized by the presence of functional endometrial tissues outside the uterine cavity. Experimental studies indicate that exposure to organochlorines can interfere with both hormonal regulation and immune function to promote endometriosis. Altered expression of metalloproteinases (MMPs) in patients with endometriosis, suggests that MMPs may play a critical role. In the endometriotic lesions, prostaglandin E2 (PGE2) produced by cyclooxygenase-2 (COX-2), binds to its EP4 receptor (EP4), and via c-Src kinase induces MMPs activation, promoting endometriosis. We examined the HCB action on MMP-2 and MMP-9 activities and expression, COX-2 levels, PGE2 signaling, and the AhR involvement in HCB-induced effects. We have used different in vitro models: (1) human endometrial stromal cell line T-HESC, (2) primary cultures of Human Uterine Fibroblast (HUF), and (3) primary cultures of endometrial stromal cells from eutopic endometrium of control (CESC) and subjects with endometriosis (EESC). Our results show that HCB enhances MMP-2 and MMP-9 activities in T-HESC, HUF and ESC cells. The MMP-9 levels were elevated in all models, while the MMP-2 expression only increased in ESC cells. HCB enhanced COX-2 and EP4 expression, PGE2 secretion and the c-Src kinase activation in T-HESC. Besides, we observed that AhR is implicated in these HCB-induced effects. In conclusion, our results show that HCB exposure could contribute to endometriosis development, affecting inflammation and invasion parameters of human endometrial cells. PMID:27038655

    Environmental and occupational exposure to bisphenol A (BPA), a chemical widely used in polycarbonate plastics and epoxy resins, has received much attention in female reproductive health due to its widespread toxic effects. Although BPA has been linked to infertility and recurrent miscarriage in women, the impact of its exposure on uterine function during early pregnancy remains unclear. In this study, we addressed the effect of prolonged exposure to an environmental relevant dose of BPA on embryo implantation and establishment of pregnancy. Our studies revealed that treatment of mice with BPA led to improper endometrial epithelial and stromal functions thus affecting embryo implantation and establishment of pregnancy. Upon further analyses, we found that the expression of progesterone receptor (PGR) and its downstream target gene, HAND2 (heart and neural crest derivatives expressed 2), was markedly suppressed in BPA-exposed uterine tissues. Previous studies have shown that HAND2 controls embryo implantation by repressing fibroblast growth factor and the MAPK signaling pathways and inhibiting epithelial proliferation. Interestingly, we observed that down-regulation of PGR and HAND2 expression in uterine stroma upon BPA exposure was associated with enhanced activation of fibroblast growth factor and MAPK signaling in the epithelium, thus contributing to aberrant proliferation and lack of uterine receptivity. Further, the differentiation of endometrial stromal cells to decidual cells, an event critical for the establishment and maintenance of pregnancy, was severely compromised in response to BPA. In summary, our studies revealed that chronic exposure to BPA impairs PGR-HAND2 pathway and adversely affects implantation and the establishment of pregnancy. PMID:27022677

    2012-09-01

    Full Text Available Abstract Background All cows experience bacterial contamination and tissue injury in the uterus postpartum, instigating a local inflammatory immune response. However mechanisms that control inflammation and achieve a physiologically functioning endometrium, while avoiding disease in the postpartum cow are not succinctly defined. This study aimed to identify novel candidate genes indicative of inflammation resolution during involution in healthy beef cows. Previous histological analysis of the endometrium revealed elevated inflammation 15 days postpartum (DPP which was significantly decreased by 30 DPP. The current study generated a genome-wide transcriptomic profile of endometrial biopsies from these cows at both time points using mRNA-Seq. The pathway analysis tool GoSeq identified KEGG pathways enriched by significantly differentially expressed genes at both time points. Novel candidate genes associated with inflammatory resolution were subsequently validated in additional postpartum animals using quantitative real-time PCR (qRT-PCR. Results mRNA-Seq revealed 1,107 significantly differentially expressed genes, 73 of which were increased 15 DPP and 1,034 were increased 30 DPP. Early postpartum, enriched immune pathways (adjusted P P SAA1/2, GATA2, IGF1, SHC2, and SERPINA14 genes were significantly elevated 30 DPP and are functionally associated with tissue repair and the restoration of uterine homeostasis postpartum. Conclusions The results of this study reveal an early activation of the immune response which undergoes a temporal functional change toward tissue proliferation and regeneration during endometrial involution in healthy postpartum cows. These molecular changes mirror the activation and resolution of endometrial inflammation during involution previously classified by the degree of neutrophil infiltration. SAA1/2, GATA2, IGF1, SHC2, and SERPINA14 genes may become potential markers for resolution of endometrial inflammation in

    Full Text Available Background: A good blood supply towards the endometrium is usually considered to be an essential requirement for implantation. Evaluating the role of endometrial and sub-endometrial blood flows detected by color Doppler sonography at the day of embryo transfer, as a predictor of pregnancy rate during IVF/ICSI programs was our main goal in this study.Materials and Methods: Seventy three infertile patients aged <38 years with basal serum FSH level<12 mIU/ml who had less than two failed attempts of ART cycles were prospectively evaluated. The cases with more than two failed IVF cycle and uterine disorders were excluded. All procedures were performed by one expert and two good quality embryos were transferred. Vaginal power color Doppler sonography was performed at the day of embryo transfer and endometrial characteristics including endometrial vascularization, area of vascularization distribution and pulsatility index were registered. Then pregnant and non-pregnant groups were compared for ultrasonographic parameters of endometrium.Results: Pregnancy occurred in 28 patients. Mean age, duration and etiology of infertility, baseline mean FSH and estradiol level at the day of Human chorionic gonadotropin (HCG injection, amount of drug administered, number of retrieved oocytes and embryos, also number and quality of transferred embryos in the pregnant and non-pregnant groups showed no statistically significant difference .On the other hand, none of the sonographic parameters reported in two groups indicated a statistically significant difference.Conclusion: Doppler ultrasonographic indices at the day of embryo transfer are not considered appropriate criteria for prediction of success rate or failure of embryo implantation.

  19. Markers of the uterine innate immune response of the mare.

    2010-05-01

    Reproductive efficiency in mares is low and persistent mating-induced endometritis (PMIE) is an important cause of subfertility. Mating-induced endometritis (MIE) an obligate precursor to PMIE, is a ubiquitous, transient inflammatory response to the presence of sperm, seminal components and pathogens. However, the specific inflammatory pathways that derive from MIE and that may also be precursors to PMIE are not clear. The ability to identify and measure robust, repeatable markers of inflammation integral to MIE may be key to understanding the progression to PMIE. The aim of the study was to (i) refine a protocol for inducing MIE and in doing so test a range of cellular and molecular parameters as valid markers of MIE to facilitate future studies of mares susceptible to PMIE (ii) concurrently identify those parameters with potential as inflammatory indicators during MIE to inform and enhance early treatment regimens in practice. Mating-induced endometritis was induced in pony mares using a stringent protocol; mares were treated intrauterine with frozen/thawed semen (n = 5; FTS) or frozen/thawed extender (n = 6: FTEx). The parameters tested were measured before treatment were compared to samples collected at strategic time points after treatment: uterine cytology using cytological (at 8, 16, 24, 48 and 72 h after treatment) or histological analysis (at 24 and 72 h); uterine bacteriology (at 24 and 72 h); secretion of prostaglandin F(2alpha) (PGF(2alpha); at 8, 16, 24, 48 and 72 h); peripheral concentrations of serum amyloid A (SAA; at 24h); endometrial mRNA gene expression, focussing upon IL8 and TLR4, as examples of genes pertinent to inflammation (at 24 h). Uterine neutrophil cell numbers in both treatment groups increased at 8 (P range of parameters tested, neutrophil cell numbers by cytological analysis and PGF(2alpha) were regarded as the most accurate markers of inflammation during MIE and important for use in practice.

    Adenofibroma is an extremely rare benign m'ullerian mixed tumor composed of epithelium and mesenchymal cells. Most uterine adenofibromas occur in the endometrium, but they rarely protrude into the vagina. To date, only a few such cases with the imaging findings have been reported. Therefore, we report here on the sonographic and magnetic resonance (MR) imaging findings of a case of endometrial adenofibroma protruding into the vaginal cavity in a 28-year-old woman. The uterine adenofibroma appeared as a large intracavitary echogenic mass containing multiple small internal cysts, and it was distending the vaginal cavity on transrectal sonography. T2- weighted MR images showed a large intracavitary mass with heterogeneous high signal intensity protruding into the vaginal cavity. On gadolinium-enhanced T1-weighted MR images, heterogeneous septa-like enhancement was noted in the mass. Although uterine adenofibroma is extremely rare, adenofibroma can be suggested as a possible diagnosis when an intracavitary uterine mass, with multiple internal small cystic components and enhancing septa-like structures, is protruding into the vaginal cavity on imaging

  1. Utility of the broccoli sign in the distinction of prolapsed uterine tumor from cervical tumor

    Objective: To describe the utility, histopathological basis, and clinical correlates of the broccoli sign. Methods: The committee on human research approved this HIPAA compliant study and waived written informed consent. Based on the records of the senior author and our multidisciplinary Gynecologic Oncology Tumor Board, we retrospectively identified thirteen women (mean age of 48.8 years; range, 34–74) with a cervical mass seen at MR imaging (n = 13) or CT (n = 5) that demonstrated the previously reported broccoli sign (i.e., a soft tissue stalk connecting the cervical mass to the uterine cavity) on one or other modality. All available clinical, imaging, and histopathological records were reviewed, with particular emphasis on initially suspected diagnosis, final proven diagnosis, and outcome. Results: Cervical cancer was the initial clinically suspected diagnosis in 6 of 13 patients. Surgical resection demonstrated prolapsed uterine tumor in all patients, consisting of endometrioid adenocarcinoma (n = 7), carcinosarcoma (n = 2), adenosarcoma (n = 1), and leiomyoma (n = 3). Excluding the three patients with leiomyomas, currently, 7 patients with malignant tumors are disease free after a mean interval of 15 months (range, 3–45) and 3 patients have been lost to follow-up. Conclusion: A stalk connecting an apparent cervical mass seen at CT or MR imaging to the endometrial cavity (“broccoli sign”) favors the diagnosis of a prolapsed uterine tumor; these prolapsed uterine tumors can often be malignant but appear to have a good prognosis.

    This study was conducted to evaluate the effects of induced endometritis on uterine blood flow in cows. Transrectal Doppler sonography was performed on uterine arteries of six cyclic cows before and for 4 days after inducing acute endometritis by intrauterine infusion of 720 mg of policresulen, and for 4 days of the following estrous cycle. Time-averaged maximum velocity (TAMV) increased (p 0.05) in the next 4 days of the same cycle. TAMV and PI values in the subsequent cycle did not differ (p > 0.05) from the values measured before infusion and showed no changes (p > 0.05) within the cycle. Blood flow parameters were not related (p > 0.05) to plasma concentrations of progesterone and estrogen. All cows showed an acute endometritis determined by histopathological findings of biopsy samples taken 1 day after infusion and fibrotic endometrial alterations detected in the subsequent cycle. No relationships were observed between fibrotic changes of the endometrium and uterine blood flow during either cycle. In conclusion, acute inflammation is accompanied by a rise in uterine blood flow, but fibrotic alterations do not seem to be related to Doppler sonographic findings. PMID:26645345

  3. Granulocytes and vascularization regulate uterine bleeding and tissue remodeling in a mouse menstruation model.

    Astrid Menning

    Full Text Available Menstruation-associated disorders negatively interfere with the quality of life of many women. However, mechanisms underlying pathogenesis of menstrual disorders remain poorly investigated up to date. Among others, this is based on a lack of appropriate pre-clinical animal models. We here employ a mouse menstruation model induced by priming mice with gonadal hormones and application of a physical stimulus into the uterus followed by progesterone removal. As in women, these events are accompanied by menstrual-like bleeding and tissue remodeling processes, i.e. disintegration of decidualized endometrium, as well as subsequent repair. We demonstrate that the onset of bleeding coincides with strong upregulation of inflammatory mediators and massive granulocyte influx into the uterus. Uterine granulocytes play a central role in regulating local tissue remodeling since depletion of these cells results in dysregulated expression of matrix modifying enzymes. As described here for the first time, uterine blood loss can be quantified by help of tampon-like cotton pads. Using this novel technique, we reveal that blood loss is strongly reduced upon inhibition of endometrial vascularization and thus, is a key regulator of menstrual bleeding. Taken together, we here identify angiogenesis and infiltrating granulocytes as critical determinants of uterine bleeding and tissue remodeling in a mouse menstruation model. Importantly, our study provides a technical and scientific basis allowing quantification of uterine blood loss in mice and thus, assessment of therapeutic intervention, proving great potential for future use in basic research and drug discovery.

    Objective: To describe the utility, histopathological basis, and clinical correlates of the broccoli sign. Methods: The committee on human research approved this HIPAA compliant study and waived written informed consent. Based on the records of the senior author and our multidisciplinary Gynecologic Oncology Tumor Board, we retrospectively identified thirteen women (mean age of 48.8 years; range, 34-74) with a cervical mass seen at MR imaging (n = 13) or CT (n = 5) that demonstrated the previously reported broccoli sign (i.e., a soft tissue stalk connecting the cervical mass to the uterine cavity) on one or other modality. All available clinical, imaging, and histopathological records were reviewed, with particular emphasis on initially suspected diagnosis, final proven diagnosis, and outcome. Results: Cervical cancer was the initial clinically suspected diagnosis in 6 of 13 patients. Surgical resection demonstrated prolapsed uterine tumor in all patients, consisting of endometrioid adenocarcinoma (n = 7), carcinosarcoma (n = 2), adenosarcoma (n = 1), and leiomyoma (n = 3). Excluding the three patients with leiomyomas, currently, 7 patients with malignant tumors are disease free after a mean interval of 15 months (range, 3-45) and 3 patients have been lost to follow-up. Conclusion: A stalk connecting an apparent cervical mass seen at CT or MR imaging to the endometrial cavity ('broccoli sign') favors the diagnosis of a prolapsed uterine tumor; these prolapsed uterine tumors can often be malignant but appear to have a good prognosis.

  6. Carcinoma of the uterine cervix

    There are few reports on uterine cancer in relation to radiation. This chapter discusses uterine cancer in A-bomb survivors, with special reference to the mortality rate, in a review of the literature. The Atomic Bomb Casualty Commission has first discovered 28 cases of uterine cancer among A-bomb survivors during the period 1953-1957. Since 1970, mortality rate from uterine cancer has been investigated statistically according to the T65D system. The Radiation Effect Research Foundation (RERF) has revealed 282 death cases from uterine cancer during the period 1950-1974. The RERF's data up to 1982 has revealed no radiation-dependent mortality from uterine cancer. More recent data (1950-1985) has revealed that mortality rate was increased by 22% in A-bomb survivors exposed to 1 Gy or more. When mortality of uterine cancer was investigated statistically using the 1968-1982 data for the population of the Research Institute for Nuclear Medicine and Biology, Hiroshima University, it was 1.2 times higher in the entire exposed group and 1.4 times higher in the group of proximally exposed A-bomb survivors (within 2 km from the hypocenter) than the non-exposed group, with statistically significant difference. It tended to be high in the group of distally exposed A-bomb survivors (who entered the city within 3 days after A-bombing) than the non-exposed group. When comparing the group of Hiroshima City with the group of Hiroshima Prefecture, mortality from uterine cancer was 1.3 times higher in the municipal group for proximally exposed A-bomb survivors and 1.3 times higher in the prefectural group for distally exposed A-bomb survivors and the others. Mortality rate was highest within one year after the acquisition of health handbook in the exposed group. (N.K.)

  8. Bovine endometrial stromal cells display osteogenic properties

    Cavirani Sandro

    2008-12-01

    Full Text Available Abstract The endometrium is central to mammalian fertility. The endometrial stromal cells are very dynamic, growing and differentiating throughout the estrous cycle and pregnancy. In humans, stromal cells appear to have progenitor or stem cell capabilities and the cells can even differentiate into bone. It is not clear whether bovine endometrial stromal cells exhibit a similar phenotypic plasticity. So, the present study tested the hypothesis that bovine endometrial stromal cells could be differentiated along an osteogenic lineage. Pure populations of bovine stromal cells were isolated from the endometrium. The endometrial stromal cell phenotype was confirmed by morphology, prostaglandin secretion, and susceptibility to viral infection. However, cultivation of the cells in standard endometrial cell culture medium lead to a mesenchymal phenotype similar to that of bovine bone marrow cells. Furthermore, the endometrial stromal cells developed signs of osteogenesis, such as alizarin positive nodules. When the stromal cells were cultured in a specific osteogenic medium the cells rapidly developed the characteristics of mineralized bone. In conclusion, the present study has identified that stromal cells from the bovine endometrium show a capability for phenotype plasticity similar to mesenchymal progenitor cells. These observations pave the way for further investigation of the mechanisms of stroma cell differentiation in the bovine reproductive tract.

    After parturition, uterine bacterial infections lead to inflammatory processes such as subclinical/clinical endometritis with high prevalence in dairy cows. Endometrial epithelial cells participate in this immune response with the production of pro-inflammatory factors. The objective of the present study was to evaluate the endometrial mRNA expression pattern of pro-inflammatory factors during a selected postpartum (pp) period. Dairy cows with three different uterine health conditions on days 24-30 pp (healthy: n = 11, subclinical endometritis: n = 10, clinical endometritis: n = 10) were sampled using the cytobrush technique. Subsequently, each cow was sampled 3 more times in weekly intervals (days 31-37 pp; days 38-44 pp; days 45-51 pp). Samples were subjected to mRNA analysis performed by RT-qPCR. Additionally, an analysis of cultivable bacteria was performed at the early/late stage of the selected puerperal period. mRNA expression of 16 candidate genes was analyzed by using two different approaches. The first approach referred to the initial grouping on days 24-30 pp to reveal long-term effects of the uterine health on the subsequent puerperal period. The second approach considered the current uterine health status at each sampling to elucidate the impact of different points in time. Long-term effects seem to appear for chemokines, prostacyclin synthase and prostaglandin D2 synthase. If related to the current uterine health, the majority of candidate genes were significantly higher expressed in endometritic cows on days 45-51 pp in contrast to earlier stages of the puerperium. Microbiological analysis revealed the significantly higher prevalence of Trueperella pyogenes findings in cows with clinical endometritis on days 24-30 pp, but no correlations were found on days 45-51 pp. In conclusion, a strong immune response to subclinical/clinical endometritis in the late puerperium may be related to the negative impact of these conditions on reproductive performance

  11. MR imaging of bladder endometriosis and its relationship with the anterior uterine wall: Experience in a tertiary referral centre

    Objective: Both the intraperitoneal seeding and the uterine-vesical extension theory have been proposed to explain the pathogenesis of bladder endometriosis. The aim of this study was to describe MR imaging findings of bladder endometriosis and involvement of the anterior uterine wall in a tertiary referral centre for endometriosis in a effort to improve diagnosis and help clarify the pathogenesis. Methods: In a single-centre, retrospective study (2004–2009), 463 consecutive patients analysed for deep infiltrating endometriosis (DIE) were studied independently by two experienced readers for the presence of bladder endometriosis. MR studies revealing bladder endometriosis were then analysed in consensus for: location, size, signal intensity characteristics, uterine involvement, continuity with adenomyosis and presence of cysts. There was histopathologic correlation in 9 patients who had undergone partial bladder resection. Results: Bladder endometriosis was diagnosed in 32 patients on MR imaging (k = 0.85). Most lesions showed heterogeneous isointensity compared to that of muscle on T2-weighed imaging, containing foci of high signal intensity, suggesting cystic ectopic endometrial glands. On T1-weighted imaging lesions showed heterogeneous isointensity with foci or small cysts, demonstrating high signal intensity, indicating hemorrhage, was observed. Uterine involvement was found in 94% of the lesions, with either “continuous” or “hourglass” configurations. Presence of contiguous adenomyosis was found in only 4 lesions. Conclusions: With MR imaging, uterine involvement in bladder endometriosis is frequently found and in most cases located subserosally, suggesting extensive DIE, favouring the intraperitoneal seeding theory

    Carbon disulfide (CS{sub 2}) may lead to spontaneous abortion and very early pregnancy loss in women exposed in the workplace, but the mechanism remains unclear. We designed an animal model in which gestating Kunming strain mice were exposed to CS{sub 2} via i.p. on gestational day 4 (GD4). We found that the number of implanted blastocysts on GD8 was significantly reduced by each dose of 0.1 LD{sub 50} (157.85 mg/kg), 0.2 LD{sub 50} (315.7 mg/kg) and 0.4 LD{sub 50} (631.4 mg/kg). In addition, both the level of DNA damage and apoptosis rates of endometrial cells on GD4.5 were increased, showed definite dose–response relationships, and inversely related to the number of implanted blastocysts. The expressions of mRNA and protein for the Bax and caspase-3 genes in the uterine tissues on GD4.5 were up-regulated, while the expressions of mRNA and protein for the Bcl-2 gene were dose-dependently down-regulated. Our results indicated that DNA damage and apoptosis of endometrial cells were important reasons for the loss of implanted blastocysts induced by CS{sub 2}. - Highlights: • We built an animal model of CS2 exposure during blastocyst implantation. • Endometrial cells were used in the comet assay to detect DNA damage. • CS2 exposure caused DNA damage and endometrial cell apoptosis. • DNA damage and endometrial cell apoptosis were responsible for embryo loss.

    2012-01-01

    Early stage endometrial cancer is generally curable. However, progress in the treatment of advanced and recurrent endometrial cancer has been limited. This has led to a shift from the use of traditional chemotherapeutic agents and radiotherapy regimens to the promising area of targeted therapy, given the large number of druggable molecular alterations found in endometrial cancer. To maximize the effects of directed targeted therapy, careful molecular characterization of the endometrial tumor ...

    During neonatal and juvenile life, mammalian uteri undergo extensive structural and functional changes, including uterine gland differentiation and development. In sheep and mice, inhibition of neonatal uterine gland development induced by progestin treatment led to a permanent aglandular uterine phenotype and adult infertility, suggesting that this strategy might be useful for sterilizing dogs and other companion animals. The goal of this study was to define temporal patterns of adenogenesis (gland development), cell proliferation, and progesterone and estrogen receptor expression in uteri of neonatal and juvenile dogs as a first step toward determining whether neonatal progestin treatments might be a feasible contraceptive approach in this species. Uteri obtained from puppies at postnatal wk 1, 2, 4, 6, or 8 were evaluated histologically and immunostained for MKI67, a marker of cell proliferation, estrogen receptor-1, and progesterone receptor. Adenogenesis was under way at 1 wk of age, as indicated by the presence of nascent glands beginning to bud from the luminal epithelium, and rapid proliferation of both luminal epithelial and stromal cells. By Week 2, glands were clearly identifiable and proliferation of luminal, glandular, and stromal cells was pronounced. At Week 4, increased numbers of endometrial glands were evident penetrating uterine stroma, even as proliferative activity decreased in all cell compartments as compared with Week 2. Whereas gland development was most advanced at Weeks 6 to 8, luminal, glandular, and stromal proliferation was minimal, indicating that the uterus was nearly mitotically quiescent at this age. Both estrogen receptor-1 and progesterone receptor were expressed consistently in uterine stromal and epithelial cells at all ages examined. In summary, canine uterine adenogenesis was underway by 1 wk of age and prepubertal glandular proliferation was essentially complete by Week 6. These results provided information necessary to

    Women experience menopause later in life. Menopause is characterized by dramatically decreased circulating estrogen level secondary to loss of ovarian function and atrophic state of genital organs. However, the molecular mechanisms for this process are not fully understood. In this study, we aimed to investigate the potential molecular mechanisms that underlie menopause-induced uterine endometrial atrophy. Our data showed that autophagy was activated in the uterine epithelial cells of both ovariectomized rats and peri-menopausal females. Endoplasmic reticulum (ER) stress occurred even prior to autophagy induction. Integrated bioinformatics analysis revealed that ER stress induced downstream decreased release of arachidonic acid (AA) and downregulation of AA/prostaglandin E2 (PGE2) axis, which led to Akt/mTOR signaling pathway inactivation. Consequently, autophagosomes were recruited and LC3-dependent autophagy was induced in uterine epithelial cells. Treatment with exogenous E2, PGE2, salubrinal or RNAi-mediated silencing of key autophagy genes could effectively counteract estrogen depletion-induced autophagy. Collectively, autophagy is a critical regulator of the uterine epithelium that accounts for endometrial atrophy after menopause. PMID:27506466

  20. Uterine fibroids associated with infertility.

    Van Heertum, Kristin; Barmat, Larry

    2014-11-01

    In recent years, there has been an increasing focus on the contributory role of uterine fibroids to infertility. The prevalence of these tumors increases with age, which becomes significant as more women are delaying childbearing. Therefore, fibroids and infertility frequently occur together. Treatment varies with fibroid location and size. The various methods of treatment include open myomectomy, laparoscopic or robot-assisted myomectomy, medical treatment, uterine artery embolization and magnetic resonance guided focused ultrasound surgery. While there is a general consensus on the treatment of submucosal fibroids, the management of intramural fibroids in the infertility patient remains controversial. This paper aims to review and summarize the current literature in regards to the approach to uterine fibroids in the infertile patient. PMID:25482490

    In a prospective open study the sterility of the uterine cavity was evaluated in 99 women admitted for hysterectomy. The indications for hysterectomy were in most cases persistent irregular vaginal bleeding and fibromyomas of the uterus. Samples for both aerobic and anaerobic bacteria, Chlamydia...... trachomatis, yeasts and viruses were taken preoperatively from the apex of the vagina and cervical os. Immediately after hysterectomy the uterus was opened under sterile conditions and samples obtained from the isthmus and fundus of the uterine cavity for microbiological examination. Wet smears were taken...

  2. Uterine and ovarian disorders in old cats: A study by ultrasonography and radiography

    Aim of this study was to examine disorders of ovaries and uteri in old domestic cats, using ultrasonography and radiography. Six intact female domestic cats, 6-9 years old that had never received any hormonal contraception were used in the study. Serum samples were taken on days 2, 4 and 6 of oestrus and analysed for oestradiol-17 beta and progesterone concentrations. On day 4 of oestrus, ovarian and uterine appearance and diameters was determined, using ultrasonography. Hysterography was performed using an infusion of a contrast medium into the cranial vagina. The measurement of uterine diameter was done using the ultrasound and the hysterogram. Cystic endometrial hyperplasia (CEH) and cystic ovaries were common abnormal features. Ultrasound showed an ovarian diameter of 1.24+-0.48 cm and a follicle diameter of 0.3-0.4 cm at mid-oestrus. Cysts in the ovaries were observed with a diameter of 0.98-2.04 (3/6). Multiple cystic structures of 0.1-0.2 cm were found in the hyperplastic endometrium (5/6). Hysterography provided an overview of the uterine appearance, hyperplasia and the cystic changes in the endometrium. The diameter of the uterine horns, measured using the ultrasound and hysterogram, was 0.66+-0.22 and 0.68+-0.18 cm, respectively (p LT 0.05). The increase and the decline of oestradiol-17 beta, and the basal level of progesterone concentration, during oestrus, indicated that the cystic ovaries did not produce these hormones. The study demonstrated the abnormal changes in the ovaries and uteri of old cats, which is likely to be the cause infertility which is particularly important in endangered wild felids. It is valuable that ultrasound and hysterogram can now be used for diagnosing the pathology of ovaries and uterine disease in cats

    Subclinical endometritis affects approximately 30% of lactating dairy cows, causing significant economic losses to the dairy industry. Yet, there is no efficient treatment available for this condition. The present study examines the effect of uterine lavage in clinically normal cows with sterile saline solution at 30 days in milk (DIM) on the percentage of polymorphonuclear cells (PMNs) detected with endometrial cytology as an indicator of subclinical endometritis. It was hypothesized uterine lavage would be a technique to reduce the number of PMNs in the uterus, and hence be beneficial for cows affected by subclinical endometritis. Cytology samples were taken by low-volume flushing from 50 Holstein Friesian cows on 30 and 40 DIM. On Day 30, cows were clinically examined and randomly assigned into a treatment and control group. In the treatment group, the cytology sampling on Day 30 was immediately followed by uterine lavage with 500-600 mL of sterile physiological saline (35-40°C). Cytology sampling was repeated in all cows at 40 DIM. Lactation numbers >2, peripheral progesterone concentrations >1 ng/mL and uterine lavage at 30 DIM all were significantly associated with lesser PMN percentages at 40 DIM (P=0.0041; 0.0187 and 0.0043, respectively). Uterine lavage might, therefore, be a useful and practical method to decrease the number of PMNs in the uterus of cattle. Results from the current study can be used as preliminary data for designing in depth therapeutic protocols for treatment of subclinical endometritis in cattle. PMID:25956200

    A 49-year-old woman, who had undergone hysterectomy for low-grade endometrial stromal sarcoma (ESS) 3 years ago, presented with a 2-wk history of lower abdominal pain. Barium enema and sigmoidoscopy disclosed a polypoid submucosal tumor. Histopathologic features of biopsy specimens from the lesion were similar to those of the resected uterine ESS. Under the diagnosis of metastatic ESS of the sigmoid colon, sigmoidectomy was performed. Microscopic examination demonstrated dense proliferation of spindle cells with little nuclear atypia, which were sometimes arranged in whorled pattern around abundant arterioles. Mitotic count is below 1 in 10 highpower fields. Immunohi-stochemically, the neoplastic cells were strongly positive for vimentin, estrogen receptor and progesterone receptor but negative for α-smooth muscle actin, S-100 protein and CD34. Thus, a final diagnosis of low-grade ESS metastasis to the sigmoid colon was made.Her postoperative course was uneventful and hormonal therapy with progestational agents is entertained.

  5. Prognostic factors in endometrial carcinoma

    The results of the combined use of surgery and radiation therapy in the treatment of endometrial carcinoma are reported. From January '74 to December '89, 89 cases were treated by means of abdominal hysterectomy followed by external radiation therapy. Actuarial survival at 5 years is 100% for stage I, 75% for stage II, and 42.86% for stage III; stage IV patients could not be evaluated. Prognostic factors were statistically significant. In stages II and III survival rates were directly related to histological grading (G1: 90.91%; G2:81.82%; G3: 25%) and to myometrial infiltration (M1: 85.71%; M2: 81.82%; M3: 70%). Generally, survival was related to age, and prognosis was better in younger patients (under 55) and depended on lymph nodal involvement (N-:88.24%, versus N+: 25%). Vaginal and pelvic recurrences were 8 (10.1%), and deaths were 13. The identification of high-risk patients will make it possible to select an even more adequate treatment

  6. Signalling pathways in endometrial cancer.

    Markowska, Anna; Pawałowska, Monika; Lubin, Jolanta; Markowska, Janina

    2014-01-01

    Carcinogenesis is a multistage process, during which the activity of signalling pathways responsible for cell cycle regulation and division is disrupted which leads to inhibition of apoptosis and enhanced proliferation. Improper activation of Wnt/β-catenin and PI3K. Akt pathways play essential role in endometrial cancers (EC), mainly type I. Mutations in APC, axin or CTNBB1 may lead to β-catenin overactivation leading to excessive gene expression. PTEN inactivation, mutations in the PIK3CA or Akt result in increased transmission in the PI3K/Akt pathway, apoptosis inhibition, intensive cell division, mTOR excitation. In non-endometrioid cancers, key mutations include suppressor gene TP53 responsible for repairing damaged DNA or apoptosis initiation. Irregularities in gene P16, encoding a protein forming the p16-cyclinD/CDK-pRb have also been described.

    Background: The sensitivity of cervical cytology for detection of glandular lesions is reported to be low. We conducted this study to assess the diagnostic accuracy of cervical Papanicolaou (Pap) smears for uterine glandular lesions and to compare the diagnostic utility of conventional and liquid-based cytology (LBC) smears for glandular lesions. Materials and Methods: Archived histopathology records of all cases reported as endocervical and endometrial adenocarcinoma in the study period were identified and the available corresponding Pap smears (in preceding 1 year) were retrieved. In addition, the Pap smears reported as glandular cell abnormalities (GCA) during the same study period were retrieved. The overall prevalence of GCA, sensitivity, and specificity of Pap smears for the detection of GCA was calculated. The diagnostic accuracy of conventional and LBC smears for the diagnosis of GCA was also compared. Results: The prevalence of GCA in our study was 0.32%. The overall specificity of Pap smears for the diagnosis of GCA was 60.8%, this was not significantly different between conventional and LBC smears (P = 0.4). The overall sensitivity of Pap smears for the detection of GCA was 41.8%; LBC smears had significantly better sensitivity as compared to conventional smears for the detection of endometrial as compared to endocervical adenocarcinoma (P Pap smears is low. The specificity of Pap smears, for diagnosis of GCA, was found to be moderate. However, the overall sensitivity of Pap smears for the detection of GCA was low, though better for LBC as compared to conventional smears. PMID:27014363

    In mammals, embryonic diapause, or suspension of embryonic development, occurs when embryos at the blastocyst stage are arrested in growth and metabolism. In the tammar wallaby (Macropus eugenii), there are two separate uteri, only one of which becomes gravid with the single conceptus at a post-partum oestrus, so changes during pregnancy can be compared between the gravid and non-gravid uterus within the same individual. Maintenance of the viable blastocyst and inhibition of further conceptus growth during diapause in the tammar is completely dependent on the uterine environment. Although the specific endocrine and seasonal signals are well established, much less is known about the cellular changes required to create this environment. Here we present the first detailed study of uterine morphology during diapause and early pregnancy of the tammar wallaby. We combined transmission electron microscopy and light microscopy to describe the histological and ultrastructural changes to luminal and glandular epithelial cells. At entry into diapause after the post-partum oestrus and formation of the new conceptus, there was an increase in abundance of organelles associated with respiration in the endometrial cells of the newly gravid uterus, particularly in the endoplasmic reticulum and mitochondria, as well as an increase in secretory activity. Organelle changes and active secretion then ceased in these cells as they became quiescent and remained so for the duration of diapause. In contrast, cells of the non-gravid, post-partum, contralateral uterus underwent sloughing and remodelling during this time and some organelle changes in glandular epithelial cells continued throughout diapause, suggesting these cells are not completely quiescent during diapause, although no active secretion occurred. These findings demonstrate that diapause, like pregnancy, is under unilateral endocrine control in the tammar, and that preparation for and maintenance of diapause requires

    Full Text Available The aim of this study was to evaluate the use of endometrial cytology and metabolic profiles for selection of donor cows in embryo transfer programmes. For this purpose, 69 clinically healthy Holstein cows were enrolled in the study. At the start of the superovulation procedure (Day 0, blood and endometrial samples were obtained to determine metabolic and uterine status, respectively. The cows were then subjected to porcine follicle stimulating hormone (pFSH superovulation treatment, and embryos were recovered after 7 days. The mean number of embryos obtained per flush was 9.89±8.21 (4.63±5.34 viable embryos, 0.82±2.01 degenerated embryos and 4.57±6.44 unfertilized ova. The following statistically significant variables were entered in a regression model: beta-hydroxybutyrate, serum cholesterol, body condition, number of calvings and percentage of neutrophils. In almost all cases, the model explained some percentage of the variance: total number of embryos, 4.8% (p<0.05; number of degenerate embryos, 4.2% (p=0.051; and number of unfertilized ova, 14.2% (p<0.01. Statistical models for the percentage of viable embryos and unfertilized ova accounted for 24.0% and 29.4% of the variance, respectively, and both were statistically significant (p<0.01. The model for the percentage of degenerated embryos was statistically significant (p<0.05 and explained 4.4% of the variance. In conclusion, we have demonstrated that positive energy balance and healthy uterus can improve ovarian response and the proportion of viable embryos in cows. Efficient tools for monitoring the metabolic and uterine status should therefore be used in bovine embryo transfer programmes.

  10. Endometrial caspase 1 and interleukin-18 expression during the estrous cycle and peri-implantation period of porcine pregnancy and response to early exogenous estrogen administration

    Full Text Available Abstract Background The role for endometrial secretion of cytokines during the establishment of pregnancy in a number of mammals is well established. The current study determined endometrial expression of caspase 1 (CASP1 and interleukin-18 (IL18 during the estrous cycle and early pregnancy, and following early estrogen administration, which induces conceptus loss during early development in pigs. Methods Gilts were hysterectomized on either D 0, 5, 10, 12, 15 and 18 of the estrous cycle, or D 10, 12, 15 or 18 of pregnancy. The abundance of endometrial CASP1 mRNA was unaffected by day of the estrous cycle, however there was a 6 and 10-fold increase in expression on D 15 and 18 of pregnancy. Endometrial expression of IL18 mRNA increased 5-fold between D 10 to 18 in cyclic and pregnant gilts. Total recoverable IL18 in uterine flushings was greater in pregnant compared to cyclic gilts on D 15 and 18. In the second experiment, mated gilts were treated with either corn oil (CO or estrogen (E on D 9 and 10 and hysterectomized on either D 10, 12, 13, 15 or 17 of pregnancy. The current study localizes the presence of CASP1 to the epithelial layer of the endometrium for the first time. Further, a day × treatment interaction was detected for endometrial CASP1 mRNA and protein abundance as E stimulated an earlier increase on D 13 compared to CO gilts. Although IL18 mRNA expression remained unaltered from the E treatment, protein abundance was significantly attenuated on D 15 and 18 in response to E treatment. Conclusions Endometrial expression of CASP1 and IL18 is associated with establishment of pregnancy in pigs. Alteration of CASP1 and IL18 following premature exposure of the uterus to estrogen during early pregnancy may contribute to conceptus loss between Days 15 to 18 of pregnancy.

    Full Text Available Abstract Background Intrauterine infusions have been widely used for the treatment of endometritis in the mare. Nevertheless, their consequences on endocrine and endometrial molecular aspects are unknown. We studied the effect of a 1% povidone-iodine solution intrauterine infusion on progesterone levels, endometrial histology and estrogen (ERα and progesterone (PR receptor distribution by immunohistochemistry. Methods Fourteen healthy mares were used in this study. Estruses were synchronized and seven mares were treated with intrauterine infusions at days 0 and 2 post ovulation of two consecutive estrous cycles. Uterine biopsy samples were taken on days 6 and 15 post ovulation. Results The treatment did not induce an inflammatory response indicating endometritis, neither affected the ERα. However, it reduced the percentage of PR positive cells (PPC on day 6 (deep glandular epithelium, control: 95.7 vs. infused: 61.5, P P = 0.07, and higher levels on day 15 compared with controls (4.4 ng/ml vs. 1.3 ng/ml, P = 0.07. Conclusion a 1% povidone-iodine infusion during days 0 and 2 post ovulation in healthy mares did not induce histological changes indicating endometritis, but altered progesterone concentrations and reduced the expression of endometrial PR at day 6 without affecting the ERα. These changes could reduce embryo survival.

    Background Epidemiologic studies are consistent in finding that women who have had at least one birth are less likely to develop endometrial cancer. Less clear is whether timing of pregnancies during reproductive life influences risk, and the degree to which incomplete pregnancies are associated with a reduced risk. Methods We evaluated pregnancy history in relation to endometrial cancer risk using data from a series of four population-based endometrial cancer case-control studies of women 45–74 years of age (1,712 cases and 2,134 controls) during 1985–2005 in western Washington State. Pregnancy history and information on other potential risk factors were collected by in-person interviews. Results Older age at first birth was associated with a reduced risk of endometrial cancer after adjustment for number of births and age at last birth (test for trend P = 0.004). The odds ratio comparing women at least 35 years of age at their first birth with those younger than 20 years was 0.34 (95% confidence interval = 0.14–0.84). Age at last birth was not associated with risk after adjustment for number of births and age at first birth (test for trend P = 0.830). Overall, a history of incomplete pregnancies was not associated with endometrial cancer risk to any appreciable degree. Conclusions In this study, older age at first birth was more strongly associated with endometrial cancer risk than was older age at last birth. To date, there remains some uncertainty in the literature on this issue. PMID:21691206

  15. Genomic instability influences the transcriptome and proteome in endometrial cancer subtypes

    Habermann Jens K

    2011-10-01

    Full Text Available Abstract Background In addition to clinical characteristics, DNA aneuploidy has been identified as a prognostic factor in epithelial malignancies in general and in endometrial cancers in particular. We mapped ploidy-associated chromosomal aberrations and identified corresponding gene and protein expression changes in endometrial cancers of different prognostic subgroups. Methods DNA image cytometry classified 25 endometrioid cancers to be either diploid (n = 16 or aneuploid (n = 9, and all uterine papillary serous cancers (UPSC to be aneuploid (n = 8. All samples were subjected to comparative genomic hybridization and gene expression profiling. Identified genes were subjected to Ingenuity pathway analysis (IPA and were correlated to protein expression changes. Results Comparative genomic hybridization revealed ploidy-associated specific, recurrent genomic imbalances. Gene expression analysis identified 54 genes between diploid and aneuploid endometrioid carcinomas, 39 genes between aneuploid endometrioid cancer and UPSC, and 76 genes between diploid endometrioid and aneuploid UPSC to be differentially expressed. Protein profiling identified AKR7A2 and ANXA2 to show translational alterations consistent with the transcriptional changes. The majority of differentially expressed genes and proteins belonged to identical molecular functions, foremost Cancer, Cell Death, and Cellular Assembly and Organization. Conclusions We conclude that the grade of genomic instability rather than the histopathological subtype correlates with specific gene and protein expression changes. The identified genes and proteins might be useful as molecular targets for improved diagnostic and therapeutic intervention and merit prospective validation.

    Farzaneh Chobsaz

    2011-01-01

    Full Text Available Background: Sildenafil is a selective inhibitor of cyclic-guanosine monphosphat-specificphosphodiesterase type 5. It increases intracellular nitric oxide (NO production in some cells.There are reports on its positive effect on uterine circulation, endometrial thickness, and infertilityimprovement. Endometrial epithelial cells (EEC play an important role in embryo attachment andimplantation. The present work investigates the effect of sildenafil on human EEC and their NOsecretion in vitro.Materials and Methods: In this experimental in vitro study, endometrial biopsies (n=10 werewashed in a phosphate buffered solution (PBS and digested with collagenase I (2 mg/ml in DMEM/F12 medium at 37°C for 90 minutes. Epithelial glands were collected by sequential filtrationthrough nylon meshes (70 and 40 μm pores, respectively. Epithelial glands were then treated withtrypsin to obtain individual cells. The cells were counted and divided into four groups: control and1, 10, and 20 μM sildenafil concentrations. Cells were cultured for 15 days at 37ºC and 5% CO2; themedia were changed every 3 days, and their supernatants were collected for the NO assay. NO wasmeasured by standard Greiss methods. Data were analyzed by one way ANOVA.Results: There was no significant difference between groups in cell count and NO secretion, but thelevel of NO increased slightly in the experimental groups. The 10 μM dose showed the highest cellcount. EEC morphology changed into long spindle cells in the case groups.Conclusion: Sildenafil (1, 10, and 20 μM showed a mild proliferative effect on human EECnumbers, but no significant change was seen in NO production.

    Background. It is widely assumed that the uterine cavity in non-pregnant women is physiologically sterile, also as a premise to the long-held view that human infants develop in a sterile uterine environment, though likely reflecting under-appraisal of the extent of the human bacterial metacommunity. In an exploratory study, we aimed to investigate the putative presence of a uterine microbiome in a selected series of non-pregnant women through deep sequencing of the V1-2 hypervariable region of the 16S ribosomal RNA (rRNA) gene. Methods. Nineteen women with various reproductive conditions, including subfertility, scheduled for hysteroscopy and not showing uterine anomalies were recruited. Subjects were highly diverse with regard to demographic and medical history and included nulliparous and parous women. Endometrial tissue and mucus harvesting was performed by use of a transcervical device designed to obtain endometrial biopsy, while avoiding cervicovaginal contamination. Bacteria were targeted by use of a barcoded Illumina MiSeq paired-end sequencing method targeting the 16S rRNA gene V1-2 region, yielding an average of 41,194 reads per sample after quality filtering. Taxonomic annotation was pursued by comparison with sequences available through the Ribosomal Database Project and the NCBI database. Results. Out of 183 unique 16S rRNA gene amplicon sequences, 15 phylotypes were present in all samples. In some 90% of the women included, community architecture was fairly similar inasmuch B. xylanisolvens, B. thetaiotaomicron, B. fragilis and an undetermined Pelomonas taxon constituted over one third of the endometrial bacterial community. On the singular phylotype level, six women showed predominance of L. crispatus or L. iners in the presence of the Bacteroides core. Two endometrial communities were highly dissimilar, largely lacking the Bacteroides core, one dominated by L. crispatus and another consisting of a highly diverse community, including Prevotella spp

    Purpose: To evaluate the efficacy of pre-myomectomy uterine artery embolization with gelatin sponge particles to reduce operative blood loss and facilitate removal of fibroids. Materials and methods: This retrospective study included 33 women (mean age, 36 years; range, 24-45 years), of whom at least 18 wished to preserve fertility. They presented with at least one large myoma (mean diameter, 90 mm; range, 50-150 mm) and had undergone preoperative uterine artery embolization with resorbable gelatin sponge by unilateral femoral approach between December 2001 and November 2008. Clinical, radiological and surgical data were available for all patients. Mean haemoglobin levels before and after surgery were compared with Student's t-test. Results: No complication or technical failure of embolization occurred. The myomectomies were performed during laparotomy (25 cases) or laparoscopy (8 cases). Dissection of fibroids was easier (mean, 3 per patient; range, 1-11), with a mean operating time of 108 {+-} 50 min (range, 30-260 min). Bloodless surgery was the rule with a mean estimated peroperative blood loss of 147 {+-} 249 mL (range, 0-800 mL). Mean pre-(12.9 {+-} 1.3 g/dL) and post-therapeutic (11.4 {+-} 1.2 g/dL) haemoglobin levels were not statistically different (p > 0.05). There was no need for blood transfusion. None of the patients required hysterectomy. The mean duration of hospital stay was 7.5 {+-} 1.3 days (range, 3-12 days). Conclusion: Preoperative uterine artery embolization is effective in reducing intraoperative blood loss and improves the chances of performing conservative surgery. It should be considered a useful adjunct to myomectomy in women at high hemorrhagic risk or who refuse blood transfusion.

  20. Radiation therapy for endometrial carcinoma

    Although pelvic irradiation has traditionally been employed as an adjunct to surgery, the role of radiation therapy as a definitive therapeutic modality continues to be controversial. One-hundred and twenty-one patients were treated for endometrial carcinoma between 1978 and 1985 at the Medical College of Virginia Hospital. These patients were divided into three groups with respect to their treatment. Group 1 consisted of 16 patients who had preoperative radiation therapy, group 2 consisted of 77 patients who had postoperative radiation therapy, and group 3 consisted of 28 patients who had radiation therapy alone. Ninety-three percent of the patients in groups 1 and 2 and 68% of patients in group 3 had stages I and II disease. In group 3, 32% of the patients had stages III and IV disease. Two-thirds of the patients in groups 1 and 2 had moderately differentiated tumor. One-third of patients in group 3 had poorly differentiated tumor. Sixty percent of the study's population in group 2 had deep myometrial invasion. The treatment doses utilized and local failures will be presented. All of the patients have been followed for a minimum period of 2 years. The observed actuarial 5-year survival was 85%, 80%, and 53%, respectively, for groups 1, 2, and 3. The overall survival of the entire patient population was 77%. There was 1 fatality secondary to small bowel complication in group 2 and another serious complication of rectovaginal fistula in group 1 requiring colostomy. Other side effects were skin reaction, diarrhea, and cystitis, which were treated symptomatically. Analysis of the authors' institution experience with adenocarcinoma of the endometrium and its management with radiation therapy is presented. Survival is correlated with stage, grade, and depth of myometrial invasion

    Full Text Available Background: Objective of current study was to assess the effect of GnRH antagonist on follicular development, premature luteinization, uterine biophysical profile and pregnancy rate in controlled ovarian stimulation with clomiphene and gonadotropins for intrauterine insemination in women with unexplained infertility. Methods: Randomised controlled trial. Minimal stimulation protocol with or without GnRH antagonist was compared. Setting: Infertility clinic, PGIMER, Chandigarh. Patients: Couples with unexplained infertility, age of female partner between 20-39 years. Intervention: GnRH antagonist 0.25 mg since follicle size 14 mm till hCG administration. Main outcome measures: Follicle characteristics, premature luteinisation, uterine biophysical profile and pregnancy rate. Results: The mean number of follicles recruited in group A was 2.32 +/- 1.01 while that in group B (receiving GnRH antagonist it was 4.10 +/- 1.69. Statistically significant increase in total biophysical profile score was observed in periovulatory phase in the antagonist group. 40% women in group A had premature luteinization whereas only 4% women in group B suffered from premature luteinization. 20% women who received GnRH antagonist conceived against only 6% in group A, this difference however was not statistically significant Conclusions: GnRH antagonist has a role in increasing the number of follicles recruited. Furthermore, GnRH antagonist can improve the total uterine biophysical profile score by improving the endometrial thickness, endometrial pattern, blood flow and decreasing the impedance to the blood flow in uterine artery. The drug can potentially help in improving pregnancy rates by decreasing the rate of premature luteinisation. [Int J Reprod Contracept Obstet Gynecol 2015; 4(1.000: 157-163

  5. Effects of adipocyte-secreted factors on decidualized endometrial cells: modulation of endometrial receptivity in vitro.

    Gamundi-Segura, Silvia; Serna, Jose; Oehninger, Sergio; Horcajadas, Jose A; Arbones-Mainar, Jose M

    2015-09-01

    Obesity is defined as an excessive accumulation of adipose tissue that may lead to health complications. Mounting evidence indicates that obesity has a negative impact on fertility. Yet, the link between adipose tissue biology and infertility remains unclear. We aimed to investigate the communication between the adipose tissue and the reproductive system and the importance of this cross talk for the development of a receptive endometrium. To that end, we generated an in vitro model with endometrial and adipocyte cell lines. Sexual hormones, progesterone and estradiol, were used to decidualize endometrial cells and sensitize adipocytes. Decidualization produced a simultaneous increase of adipokine receptors in endometrial cells paralleling changes in their receptivity status. Furthermore, sensitization of 3T3-L1 adipocytes increased mRNA levels of leptin and resistin and decreased the expression of adiponectin and chemerin levels. This was accompanied by increased isoproterenol-induced lipolysis and reduced insulin-stimulated glucose uptake. Lastly, conditioned culture medium of those sensitized adipocytes was used to feed endometrial cells. This treatment resulted in (i) upregulation of genes previously identified as positive regulators of endometrial receptivity, such as leukemia inhibitory factor and glutathione peroxidase 3, and (ii) downregulation of interleukin-15 and mucin1, both genes negatively related with endometrial receptivity. Our results indicate that the endocrine communication between adipose tissue and the reproductive system is bidirectional and stress the importance of the adipose tissue to modulate the reproductive fitness.

    Background: Magnetic resonance (MR) imaging has been established as the best imaging modality for the detection, localization, and staging of uterine cancers. Recently, the usefulness of diffusion-weighted imaging (DWI) in the diagnosis of cancers has been reported in several studies. Purpose: To calculate the apparent diffusion coefficient (ADC) values of normal uterine zones as well as benign and malignant uterine diseases, and to determine a cut-off ADC value for the quantitative detection of uterine malignancies with DWI. Material and Methods: Eighty-seven patients (mean age 53 years) with 107 benign and malignant uterine pathologies and 50 healthy controls (mean age 38 years) were enrolled in the study. DWI was performed with b factors of 0, 500, and 1000 s/mm2. Results: The ADC values of benign and malignant lesions were compared using Student's t test. The mean and the standard deviation of the ADC values of the control group were as follows: myometrium 1.76+-0.19x10-3 mm2/s, junctional zone 0.99+-0.18x10-3 mm2/s, endometrium 1.65+-0.33x10-3 mm2/s, and cervix 1.71+-0.17x10-3 mm2/s. There was a statistically significant difference among the ADC values of normal myometrium and leiomyomas (1.47+-0.36x10-3 mm2/s; P<0.009), endometrium and endometrial carcinomas (0.86+-0.13x10-3 mm2/s; P<0.001), myometrium-junctional zone and adenomyosis (1.24+-0.20x10-3mm2/s; P<0.001), and cervix and cervical carcinomas (0.91+-0.14x10-3 mm2/s; P<0.001). The ADC values differed significantly between malignant (0.88+-0.11) and benign lesions (1.55+-0.33; P<0.01). A cut-off value for malignant lesions of 1.05x10-3 mm2/s yielded a sensitivity, specificity, and accuracy of 95.83%, 94.55%, and 94.94%, respectively. Conclusion: The present study shows that ADC measurements have the potential to quantitatively differentiate between normal and cancerous tissues of the uterine zones. We propose adding DWI as an adjunct sequence in the MR protocol for the assessment of uterine lesions.

  7. The genomics and genetics of endometrial cancer

    2012-03-01

    Full Text Available Andrea J O’Hara,  Daphne W Bell National Human Genome Research Institute, Cancer Genetics Branch, National Institutes of Health, Bethesda, MD, USAAbstract: Most sporadic endometrial cancers (ECs can be histologically classified as endometrioid, serous, or clear cell. Each histotype has a distinct natural history, clinical behavior, and genetic etiology. Endometrioid ECs have an overall favorable prognosis. They are typified by high frequency genomic alterations affecting PIK3CA, PIK3R1, PTEN, KRAS, FGFR2, ARID1A (BAF250a, and CTNNB1 (β-catenin, as well as epigenetic silencing of MLH1 resulting in microsatellite instability. Serous and clear cell ECs are clinically aggressive tumors that are rare at presentation but account for a disproportionate fraction of all endometrial cancer deaths. Serous ECs tend to be aneuploid and are typified by frequent genomic alterations affecting TP53 (p53, PPP2R1A, HER-2/ERBB2, PIK3CA, and PTEN; additionally, they display dysregulation of E-cadherin, p16, cyclin E, and BAF250a. The genetic etiology of clear cell ECs resembles that of serous ECs, but it remains relatively poorly defined. A detailed discussion of the characteristic patterns of genomic alterations that distinguish the three major histotypes of endometrial cancer is reviewed herein.Keywords: endometrial, cancer, genomics, genetics, sporadic

    2015-08-01

    Full Text Available We are reporting 3 cases of the uterine corpus with collision of endometrioid adenocarcinoma (EAC with endometrial stromal sarcoma (ESS. The patients' ages ranged from 36 to 59 years old. The major clinical presentation was abnormal uterine bleeding. Microscopically, all 3 cases presented with 2 separate components, EAC Grade 1 and ESS (one low grade and two high grades. The EAC component ranged from 10% to 70%, and the ESS component ranged from 30% to 70% of total tumor volume. The EAC component was stage 1A in two cases and stage II in one case. The ESS component was stages IA, IIB, and IIIB. Adjuvant hormonal therapy was administrated to one patient while a second patient was treated with chemo/radiation therapy. Two patients were still alive with no evidence of disease at 4 years post-therapy. One patient was lost for follow-up. Collision tumor should be distinguished from carcinosarcoma due to its different treatment modality, outcome and, prognosis.

    2016-04-15

    There are concerns regarding reproductive toxicity from consumption of soy foods, including an increased risk of endometriosis and endometrial cancer, as a result of phytoestrogen consumption. In this study, female rats were fed AIN-93G diets made with casein (CAS) or soy protein isolate (SPI) from postnatal day (PND) 30, ovariectomized on PND 50 and infused with 5 μg/kg/d 17β-estradiol (E2) or vehicle. E2 increased uterine wet weight (Pestrogen receptor (ER)α to the promoters of ER-responsive genes after SPI feeding. The major E2 up-regulated uterine pathways were carcinogenesis and extracellular matrix organization, whereas SPI feeding up-regulated uterine peroxisome proliferator activated receptor (PPAR) signaling and fatty acid metabolism. The combination of E2 and SPI resulted in significant regulation of 504 fewer genes relative to E2 alone. The ability of E2 to induce uterine proliferation in response to the carcinogen dimethybenz(a)anthracene (DMBA) as measured by expression of PCNA and Ki67 mRNA was suppressed by feeding SPI (Pselective estrogen receptor modulator (SERM) interacting with a small sub-set of E2-regulated genes and is anti-estrogenic in the presence of endogenous estrogens.

    2009-06-01

    Full Text Available Background : Office hysteroscopy with endometrial biopsy is usually the first investigation for abnormal uterine bleeding and other uterine diseases. Aims: To evaluate the effect of oral drotaverine with mefenamic acid on pain perception during hysteroscopy and endometrial biopsy and to compare it with that of paracervical block using 1% lignocaine and with that of intravenous sedation using diazepam with pentazocine. Settings and Design : Outpatient gynecological department and open randomized trial. Materials and Methods : One hundred twenty women undergoing hysteroscopy and endometrial biopsy were randomized into 3 groups. Group I received tablet containing drotaverine hydrochloride (80 mg + mefenamic acid (250 mg, group II received lignocaine paracervically and group III received intravenous diazepam. The intensity of pain during the procedure, 30 and 60 minutes later on visual analog scale (VAS was assessed. Statistical Analysis : Statistical analysis was performed using Kruskal-Wallis test, with the Bonferroni correction, the t test, and the χ2 test. Results: Groups were similar in age, parity, vaginal birth or relevant medical history. A statistically significant difference in pain scores was noted among the 3 groups during the procedure (group I, 4.13± 1.28; group II, 5.93± 1.26; group III, 5.58± 1.51, (P< 0.001; as well as 30 minutes later (group I, 1.78± 0.89; group II, 2.53± 0.81; group III, 2.23± 0.94, (P< 0.001 and 60 minutes later (group I, 1.2± 0.46; group II, 1.98± 0.83; group III, 1.68± 0.75, (P< 0.001. VAS at different time intervals among the groups was also statistically significant. No adverse effects were observed. Conclusions : Oral drotaverine with mefenamic acid is effective in women undergoing hysteroscopy and endometrial biopsy.

  11. Oral contraception and risk of endometrial cancer

    2011-10-01

    Full Text Available Alfred O Mueck1, Harald Seeger1, Xiangyan Ruan2 1Department of Endocrinology and Menopause, University Women's Hospital of Tuebingen, Tuebingen, Germany; 2Department of Gynecological Endocrinology, Beijing Obstetrics and Gynecology Hospital, Capital Medical University, Beijing, China Abstract: No placebo-controlled studies concerning hormonal contraception in general have been published, and only investigations on biological mechanisms and observational clinical studies are available. Thus, associations can be described but not their causality. Experimental studies strongly suggest protective effects of the progestagen component of hormonal contraception against development of estrogen-related (type 1 endometrial cancer. In light of this research, it seems biologically plausible that, in more than 20 published studies, a reduction in endometrial cancer risk was achieved in up to 50% of users of combined oral contraceptives (COC, compared with nonusers. Few data exist for progestin-only oral preparations. However, in view of the mechanisms involved, a reduction in cancer risk should also be expected. Whereas hormonal dose-dependency has been investigated in only a few studies, which showed a stronger risk reduction with increasing progestagenic potency, a decreased risk dependent on duration of use has been clearly demonstrated, and after stopping COC this effect has persisted for up to 20 years. Possible confounders, including family history, parity, and smoking, have been investigated in a few studies, with only a minor impact on hormonal effect of endometrial cancer risk, with the exception of obesity, which was a strong risk factor in most but not all studies. There are obvious differences in the incidence of endometrial cancer in women using COC when evaluated in absolute numbers for Western and Asian countries, being about 3–5-fold higher in the US than in Asia. Further research should include the noncontraceptive benefit of COC

    2010-04-01

    Full Text Available Abstract Background Irregular uterine bleeding is the major side effect of, and cause for, discontinuation of long-term progestin-only contraceptives (LTPOCs. The endometria of LTPOC-treated women display abnormally enlarged, fragile blood vessels (BV, decreased endometrial blood flow and oxidative stress. However, obtaining sufficient, good quality tissues have precluded elucidation of the mechanisms underlying these morphological and functional vascular changes. Methods The current study assessed the suitability of the guinea pig (GP as a model for evaluating the uterine effects of LTPOC administration. Thus GPs were treated with a transdermal pellet for 21 days and examined for endometrial histology, angiogenic markers as well as markers of oxidative stress and apoptosis. Results and Discussion We now demonstrate that GP uteri were enlarged by both estradiol (E2 and medroxyprogesterone acetate (MPA (p Conclusions LTPOC exposure alters endometrial vascular and tissue morphology consistent with oxidative stress and apoptosis in a complex interplay with endogenous estrogens. These findings are remarkably similar to in vivo change observed in the human uterus following LTPOC administration. Hence, the GP is an excellent model for the study of LTPOC effects on the uterus and will be extremely useful in determining the mechanistic pathways involved in this process which cannot be conducted on humans.

  14. Insights into endometrial serous carcinogenesis and progression.

    Fadare, Oluwole; Zheng, Wenxin

    2009-01-01

    Endometrial serous carcinomas (ESC) constitute only approximately 10% of endometrial cancers, but have a substantially higher case-fatality rate than their more common endometrioid counterparts. The precise composite of factors driving endometrial serous carcinogenesis and progression remain largely unknown, but we attempt to review the current state of knowledge in this report. ESC probably do not evolve through a single pathway, and their underlying molecular events probably occur early in their evolution. TP53 gene mutations occur in 22.7 to 96% of cases, and p53 protein overexpression is seen in approximately 76%. By gene expression profiling, p16 is upregulated in ESC significantly above both normal endometrial cells and endometrioid carcinomas, and 92-100% of cases display diffuse expression of the p16 protein by immunohistochemistry (IHC). Together, these findings suggest dysregulation of both the p16(INKA)/Cyclin D-CDK/pRb-E2F and the ARF-MDM2-p53 cell cycle pathways in ESC. By IHC, HER2/neu is overexpressed (2+ or 3+) in approximately 32.1% of ESC, and approximately 54.5% of cases scored as 2+ or 3+ by IHC display c-erbB2 gene amplification as assessed by fluorescent in situ hybridization. Genetic instability, typically manifested as loss of heterozygosity in multiple chromosomes, is a common feature of ESC, and one study found loss of heterozygosity at 1p32-33 in 63% of cases. A subset of ESC display protein expression patterns that are characteristic of high grade endometrial carcinomas, including loss of the metastasis suppressor CD82 (KAI-1) and epithelial-to-mesenchymal transformation, the latter manifested as E-cadherin downregulation, P-cadherin upregulation, and expression of epithelial-to-mesenchymal transformation-related molecules such as zinc-finger E-box-binding homeobox 1 (ZEB1) and focal adhesion kinase. Preliminary data suggests differential patterns of expression in ESC of some isoforms of claudins, proteases, the tumor invasiveness and

  15. Comparative analysis of P16 and P53 expression in uterine malignant mixed mullerian tumors.

    Recent studies have shown that, in addition to cervical carcinomas, a substantial proportion of endometrial adenocarcinomas are also immunoreactive with p16. The expression of p16 in uterine malignant mixed mullerian tumors (MMMTs), in contrast, has not yet been analyzed in a large series. To our knowledge, we present the first study assessing p16 expression in both components of MMMTs. We performed p16 and p53 immunostains on 30 cases of uterine MMMTs. Both the epithelial and mesenchymal components were subclassified; p16 and p53 immunoreactions were assessed using a semiquantitative scoring system. p16 overexpression was noted in the carcinomatous component in 96.7% (29/30), and in the sarcomatous component in 86.7% (26/30) of cases. In comparison, p53 immunoreactivity was present in the carcinomatous component in 76.7% (23/30), and in the sarcomatous component in 83.3% (25/30) of cases. p16 immunoreactivity was more intense and diffuse than p53 in 40% of type I, 30% of type II carcinomas, and 27% of sarcomatous components. There was no significant difference in p16 or p53 immunoreactivity between the homologous and heterologous sarcomas. The concordance rates for p16 and p53 immunoreactivity between the 2 components were 83% and 90%, respectively. We conclude that p16 immunostain is positive in the vast majority of uterine MMMTs with no significant difference in staining between the 2 components. Compared with p53, p16 immunoreactivity is significantly more intense and diffuse in both components. Our findings indicate that alterations in the p16-Rb pathway play an important role in the pathogenesis of uterine MMMTs. PMID:19851197

  16. Endometrial carcinoma occuring from polycystic ovary disease : A case report

    Endometrial carcinoma usually occurs in postmenopausal women ; less than 5% occurs in women under the age of 40. Up to one quarter of endometrial carcinoma patients below this age have PCO(polycystic ovary disease, Stein-Leventhal syndrome). The increased incidence of endometrial carcinoma in patients with PCO is related to chronic estrogenic stimulation. We report MR imaging in one case of endometrial carcinoma occuring in a 23 year old woman with PCO and had complained of hypermenorrhea for about three years. On T2-weighted MR image the endometrial cavity was seen to be distended with protruded endometrial masses of intermediate signal intensity, and the junctional zone was disrupted beneath the masses. Both ovaries were best seen on T2-weighted MR imaging and showed multiple small peripheral cysts and low signal-intensity central stroma

    Full Text Available Abstract. Uterine leiomyoma (UL is a hormone-dependent benign tumor of uterus. Social significance of UL is stipulated by its high rate among fertile females. Scarce data exist about the impact of cytokines in UL progression. Th1/Th2 paradigm is one of crucial points in modern immunology. Evaluation of cytokines involved into either type of immune response is of special significance for studying the diseases accompanied by the changes of extracellular matrix, e.g., leiomyomas. In present study, we analyzed peritoneal fluids from UL patients, with multiplex detection of IL-2, IL-4, IL-5, IL-10, IL-12, IL-13, GM-CSF, IFN-γ and TNF-α (Th1/Th2 panel, by means of a Bio-Plex® instrument (Bio-Rad, USA. Twenty-seven patients were observed in our study (20 patients with UL, and 7 myoma-free women (a group of comparison. The mean age of the patients was 43.5±0.6 years. The duration of UL ranged from 0 to 18 years. As a result, the levels of IL-10, GM-CSF, IFN-γ and TNF-α in patients with long-existing UL (over 5 years were significantly higher (p<0,05 than in group with a disease story of <5 years. IFN-γ values in peritoneal fluid patients with UL did inversely correlate with uterine size. Moreover, the levels of IFN-γ in patients with smaller uterine volume (<8 weeks of pregnancy were increased in relation to the group with larger tumor size. IL-10 contents were increased in the patients with adenomyosis, rapid and slow growth of UL, and in both types of tumor (simple and proliferative. Increased IL-5 levels were observed in the patients with single tumor nodules (as related to the patients bearing multiple nodes, and comparison group. Furthermore, intramural and subserosal location of nodes was characterized by increased levels of IL-5. In the patients free of adenomyosis, IL-5 value was increased against the comparison group. The changes in IL-2, IL-4, IL-12 and IL-13 levels in patients with UL were not statistically significant.

  18. Large cell neuroendocrine carcinoma originating from the uterine endometrium: a report on magnetic resonance features of 2 cases with very rare and aggressive tumor

    2012-06-01

    Full Text Available Neuroendocrine carcinomas (NEC of the female genital tract are aggressive and uncommon tumors, which usually involve the uterine cervix and ovary, and are seen very rarely in the endometrium. Only less than 10 cases of large cell NEC (LCNEC of the endometrium have been reported in the literature and their radiological findings are not well described. We report here two cases of pathologically proven LCNEC of the uterine endometrium. In both cases, the uterine body was enlarged and the tumor occupied part of the uterine cavity. Endometrial mass exhibited heterogeneous high intensity on T2-weighted magnetic resonance (MR images, and diffusion-weighted MR images revealed high intensity throughout the tumor, consistent with malignancy. LCNEC is a highly malignant neoplasm without particular findings in terms of diagnostic imaging and pathology, so its preoperative definitive diagnosis is very difficult. However, when laboratory test, pathologic diagnosis and MR imaging suggest a poorly differentiated uterine malignancy, positron emission tomography-computed tomography scan should be performed as a general assessment to help with diagnosis.

    Phosphatase and tensin homolog (PTEN) is a protein that acts as a tumor suppressor by dephosphorylating the lipid second messenger phosphatidylinositol 3,4,5-trisphosphate. Loss of PTEN function has been implicated in the pathogenesis of a number of different tumors, particularly endometrial carcinoma (ECa). ECa is the most common neoplasia of the female genital tract. Our study evaluates an association between the morphological appearance of endometrial hyperplasia and endometrial carcinoma and the degree of PTEN alterations. A total of 45 endometrial biopsies from Slovak women were included in present study. Formalin-fixed and paraffin-embedded tissue samples with simple hyperplasia (3), complex hyperplasia (5), atypical complex hyperplasia (7), endometrioid carcinomas G1 (20) and G3 (5), and serous carcinoma (5) were evaluated for the presence of mutations in coding regions of PTEN gene, the most frequently mutated tumor suppressor gene in endometrial carcinoma. 75% of the detected mutations were clustered in exons 5 and 8. Out of the 39 mutations detected in 24 cases, 20 were frameshifts and 19 were nonsense, missense, or silent mutations. Some specimens harboured more than one mutation. The results of current study on Slovak women were compared to a previous study performed on Polish population. The two sets of results were similar. PMID:26114084

    Persistent breeding-induced endometritis is ranked as the third most common medical problem in the adult mare and leads to enormous economic loss in horse breeding. In mares suffering from persistent breeding-induced endometritis, increased amounts of intrauterine (i.u.) fluid or viscous mucus in estrus or after breeding may act as a barrier for sperm and can contribute to low fertility. Current therapies of these mares aim to eliminate i.u. fluid and mucus by uterine lavage and/or administration of ecbolic drugs. Recently, i.u. administration of N-acetylcysteine (NAC) has been shown to support therapy in mares with endometritis. It was the objective of the present study to investigate effects of an oral administration of NAC on the viscosity of i.u. fluid in estrous mares. It was hypothesized that oral treatment with NAC reduces the viscosity of i.u. fluid and has a positive effect on the inflammatory response of the endometrium. Mares (n = 12) were included in the study as soon as estrus was detected (ovarian follicle >3.0 cm and endometrial edema), which was defined as Day 1. They were randomly assigned to a treatment (10 mg/kg NAC on Days 1-4) or a control group (no treatment). On days 1 and 5 i.u. mucus was collected and its rheologic properties were accessed. On Day 5, endometrial biopsies were obtained and evaluated for integrity of the luminal epithelium, number of polymorphonuclear neutrophils (PMN), staining for cyclooxygenase 2 (COX2), staining with Kiel 67 antigen (Ki-67), lectins and periodic acid Schiff (PAS). In the treatment group, viscosity of i.u. mucus increased significantly between Days 1 and 5 (P NAC treatment the mean number of PMN in endometrial biopsies was significantly lower compared to mares of the control group (1.9 ± 0.3 vs. 4.8 ± 0.4; P NAC treatment compared to control mares (P mucus in deep uterine glands differed significantly between groups (both P NAC treatment does not reduce viscosity of uterine mucus but has an

    Infectious infertility in the mare is clinically well described, little is however known about the systemic acute phase reaction (APR) and local immunological responses accompanying equine endometritis. The aim of this study was to monitor selected markers of the APR in the systemic circulation and to correlate them to the local innate immune response in the uterus during infectious endometritis. Six adult standard bred mares received an intrauterine infusion of 10(9)CFU Escherichia coli. Blood samples were obtained before (0 h) and 3, 6, 12, 24, 36, 48, 72, 96 and 120 h post inoculation (pi), and endometrial biopsies were sampled before, and 3, 12, 24, 48 and 72 h pi. The infectious endometritis elicited a systemic APR with significantly increased concentrations of the acute phase proteins (APPs) serum amyloid A (SAA) and fibrinogen. Relative gene expression analyses were performed on extracted RNA from endometrial biopsies using quantitative real-time PCR and specific primers for SAA and pro- and anti-inflammatory cytokines. Expression of SAA was significantly up-regulated at 3 and 12h pi, and a significant up-regulated expression of IL-1β, TNFα, IL-8 and IL-10 was observed at 3h pi. Plasma concentration of SAA was significantly correlated to endometrial SAA expression. The results of the present study demonstrate that endometritis gives rise to a systemic APR and an up-regulated endometrial gene expression of SAA and several pro-and anti-inflammatory cytokines. Understanding endometrial expression of acute phase proteins and selected cytokines contributing to uterine immunity in equine endometritis could improve understanding of events leading to infertility in the mare and help identify candidate genes of mediators/markers for diagnostic use.

    2015-01-01

    Embryo implantation requires a reciprocal interaction between the blastocyst and endometrium and is associated with complex regulatory mechanisms. Since their discovery, microRNAs became prominent candidates providing missing links for many biological pathways. In recent years, microRNAs were implicated as one of the important players in regulation of various biological and physiological endometrial related processes. This chapter aims to present recent knowledge pertaining to the diverse aspects of microRNAs in the embryo-endometrial relationship. We will focus on the role of microRNAs in decidualization and their part in natural and stimulated cycles. Next, we will present recent studies deliberating the role of microRNAs in recurrent pregnancy loss and in the important phenomenon of recurrent implantation failure.

    Cystic fibrosis transmembrane conductance regulator (CFFR)is a cAMP-activated chloride channel expressed in a wide variety of epithelial cells,mutations of which are responsible for the hallmark defective chloride secretion observed in cystic fibrosis(CF).Although CFTR has been implicated in bicarbonate secretion,its ability to directly mediate bicarbonate secretion of any physiological significance has not been shown.We demonstrate here that endometriaI epithelial ceils possess a CFTR-mediated bicarbonate transport mechanism.Co-culture of sperm with endometrial ceils treated with antisense oligonucleotide against CFTR,or with bicarbonate secretion-defective CF epithelial cells,resulted in lower sperm capacitation and egg-fertilizing ability.These results are consistent with a critical role of CFTR in controlling uterine bicarbonate secretion and the fertilizing capacity of sperm,providing a link between defective CFTR and lower female fertility in CF.

  8. Uterine sarcoma incidental in infertile women: experience in a tropical hospital

    Uterine sarcoma is an uncommon gynaecological malignancy. Diagnosis in its early stage and management is challenging especially in a resource poor setting. The objective of the study is to evaluate the clinico-pathologic presentation of uterine sarcoma in 9 subfertile patients that underwent surgery for seemingly benign uterine diseases. Nine consecutive infertile women with intra-operative diagnosis of uterine sarcoma were reviewed over a period of 5.5 years. The nine patients were pre-operatively misdiagnosed with uterine fibroid in 7 (77.8%) patients and adenomyosis uteri in 2 (22.2%) patients. The patients mean age was 39.2 years with a range of 36 to 47 years. Parity ranged from para 0 to para 3. Of the nine patients, 7 (77.8%) presented with secondary infertility and two (22.2%) patients with primary infertility. Clinical presentations were mainly abdomino - pelvic mass (100%), pelvic pain (77.8%) and abnormal uterine bleeding in (77.8%) of patients. Three (33.3%) of the 9 patients had history of myomectomy. Pre-operative hysterosalpingogram revealed that six (66.7%) patients had bilateral tubal blockage, two (22.2%) patients had unilateral tubal blockage and one (11.1%) patient had bilateral patent fallopian tubes. Six (66.7%) patients had hydrosalpinges. Clinical staging of malignancy was stage Ic in seven patients, stage IIa and IIb in the remaining two patients. Histologic classifications were leiomyosarcoma in six patients and endometrial stromal sarcoma in three patients. Treatments offered were surgery alone in six (66.7%) patients, surgery with adjuvant chemotherapy for 2 (22.2%) patients and one (11.1%) patient had surgery with adjuvant radiotherapy. Case fatality was 77.8% with a year of diagnosis. In a resource constrained setting, due to limitations in making diagnosis in the early stage of the disease, a high index of suspicion is needed in all elderly infertile women presenting with seemingly benign abdomino pelvic mass.

    Dinkelspiel, Helen E.; Wright, Jason D.; Lewin, Sharyn N.; Herzog, Thomas J.

    2013-01-01

    Although the contemporary management of endometrial cancer is straightforward in many ways, novel data has emerged over the past decade that has altered the clinical standards of care while generating new controversies that will require further investigation. Fortunately most cases are diagnosed at early stages, but high-risk histologies and poorly differentiated tumors have high metastatic potential with a significantly worse prognosis. Initial management typically requires surgery, but the ...

    2013-01-01

    Full Text Available Although clinical trials of molecular therapies targeting critical biomarkers (mTOR, epidermal growth factor receptor/epidermal growth factor receptor 2, and vascular endothelial growth factor in endometrial cancer show modest effects, there are still challenges that might remain regarding primary/acquired drug resistance and unexpected side effects on normal tissues. New studies that aim to target both genetic and epigenetic alterations (noncoding microRNA underlying malignant properties of tumor cells and to specifically attack tumor cells using cell surface markers overexpressed in tumor tissue are emerging. More importantly, strategies that disrupt the cancer stem cell/epithelial-mesenchymal transition-dependent signals and reactivate antitumor immune responses would bring new hope for complete elimination of all cell compartments in endometrial cancer. We briefly review the current status of molecular therapies tested in clinical trials and mainly discuss the potential therapeutic candidates that are possibly used to develop more effective and specific therapies against endometrial cancer progression and metastasis.

    2013-04-01

    Full Text Available Background: Dysfunctional Uterine Bleeding (DUB is the most common cause of abnormal uterine bleeding and is a major indication for referral to gynecological clinics. There are very few studies comparing the effect of ormeloxifene and progesterone in DUB. The objective of the study was to assess the efficacy and safety of Ormeloxifene in DUB and compare it with Norethisterone. Methods: Hundred women presenting with DUB were randomly allocated to 2 equal groups, Group-A, which received 60mg ormeloxifene twice a week for 12 weeks followed by 60mg once a week for next 12 weeks and Group-B, which received 5mg norethisterone twice daily for 21 days for 6 cycles. The primary outcomes were reduction in menstrual blood loss [measured by fall in PBAC (Pictorial Blood loss Assessment Chart score and subjective assessment], rise in hemoglobin level and decrease in endometrial thickness. Results: The reduction in mean PBAC score with ormeloxifene (216 to 88 was significantly more than with norethisterone (262 to 162 at 3 months (p<0.01. The rise in hemoglobin concentration and fall in endometrial thickness were also significantly more with ormeloxifene than norethisterone (7.52g% to 9.2g% vs. 7.48g% to 8.4g%, p<0.05, and 12.12mm to 9.46mm vs. 12.05mm to 10.7mm, p<0.05, respectively. Further improvement at 6 months was much more with ormeloxifene. No major side effects were reported in any group. Conclusions: Both drugs are effective in treating DUB, but ormeloxifene is superior to norethisterone in reducing menstrual blood loss. [Int J Reprod Contracept Obstet Gynecol 2013; 2(2.000: 194-198

    The prognosis of endometrial cancer is strongly associated with stage at diagnosis, suggesting that early detection may reduce mortality. Women who are diagnosed with endometrial carcinoma often have a lengthy history of vaginal bleeding, which offers an opportunity for early diagnosis and curative treatment. We performed DNA methylation profiling on population-based endometrial cancers to identify early detection biomarkers and replicated top candidates in two independent studies. We compared DNA methylation values of 1,500 probes representing 807 genes in 148 population-based endometrial carcinoma samples and 23 benign endometrial tissues. Markers were replicated in another set of 69 carcinomas and 40 benign tissues profiled on the same platform. Further replication was conducted in The Cancer Genome Atlas and in prospectively collected endometrial brushings from women with and without endometrial carcinomas. We identified 114 CpG sites showing methylation differences with p values of ≤ 10(-7) between endometrial carcinoma and normal endometrium. Eight genes (ADCYAP1, ASCL2, HS3ST2, HTR1B, MME, NPY and SOX1) were selected for further replication. Age-adjusted odds ratios for endometrial cancer ranged from 3.44 (95%-CI: 1.33-8.91) for ASCL2 to 18.61 (95%-CI: 5.50-62.97) for HTR1B. An area under the curve (AUC) of 0.93 was achieved for discriminating carcinoma from benign endometrium. Replication in The Cancer Genome Atlas and in endometrial brushings from an independent study confirmed the candidate markers. This study demonstrates that methylation markers may be used to evaluate women with abnormal vaginal bleeding to distinguish women with endometrial carcinoma from the majority of women without malignancy.

    In mice and sheep, neonatal administration of progesterone or progestins inhibited development of uterine glands. The aims of the present study were (1) to describe uterine gland development on postnatal Days 6 to 8 and (2) to evaluate the effects of a single postnatal administration of a progestin on reproduction and adult uterine glands morphology and function in domestic cats. Necropsy was performed on three 1-week-old female cats which had died unrelated to this study. Ten female kittens were randomly assigned within the first 24 hours of birth to: medroxyprogesterone acetate 10 mg/animal subcutaneously (MPA; n = 6) or placebo (PLC; n = 4) and followed up until puberty when they were mated. Twenty-four days after the end of estrus, ovulation and pregnancy were diagnosed by serum progesterone measurement and ultrasonography, respectively. Then, all the cats were ovariohysterectomized. After necropsy or surgery, the excised organs were histologically evaluated. Seven queens ovulated (4 of 6 MPA and 3 of 4 PLC; P > 0.1) and were pregnant (P > 0.1). Four MPA cats presented endometrial hyperplasia and one of them developed a pyometra. The 1-week-old females presented uterine glands in the stage of budding and incipient penetration of the glandular epithelium into the underlying stroma. The MPA-treated queens revealed that the area occupied by uterine glands per square-micrometer (0.55 ± 0.2 vs. 0.49 ± 0.2; P > 0.1) and the height of the glandular epithelium (μm; 24.5 ± 6.7 vs. 24.4 ± 7.2; P > 0.1) did not differ from those of the PLC group. Neither significant gross nor microscopical differences were also found for ovaries (P > 0.1). It is concluded that 1-week-old kittens had an incipient stage of uterine gland development and that a single postnatal supraphysiological dose of MPA did not alter uterine adenogenesis in this species. Furthermore, this treatment seemed to predispose to uterine disease without prevention of fertility. PMID:26534826

    Uterine fibroid is the most common tumor of female reproductive organs. The role of relaxin signaling in leiomyoma development was analyzed. We used 23 matched pairs of leiomyoma and normal myometrium samples to compare the expression of relaxin family peptide receptors RXFP1, RXFP2, caveolin 1, desmin, steroid receptors and their co-factors NCOR1 and NCOR2. The expression of RXFP1 evaluated by quantitative RT-PCR was down-regulated in fibroid tissues. Relaxin or INSL3 treatment suppressed TG...

  16. Treatment and clinical behavior of endometrial endometrioid adenocarcinoma

    Cases of endometrial carcinoma treated in a university hospital between 1986 and 1998 were analyzed. More specifically, cases of endometrial carcinoma treated at Kumamoto University Hospital during the past 13 years were analyzed in terms of additional treatment given as adjuvant therapy after surgery. Among the total of 175 cases of endometrial carcinoma, surgery was the primary treatment modality in 173 (98.9%) and the other 2 (1.1%) were treated by chemotherapy and/or radiotherapy without surgery. Of the 173 surgical cases, 158 (91.4%) were cases of endometrioid adenocarcinoma, and after excluding the cases of double cancer, the remaining 147 cases were included in the analysis. At Kumamoto University hospital, radical hysterectomy and pelvic lymphadenectomy have been performed in cases in which cervical invasion is indicated by hysteroscopy and/or MRI, invasion of the muscle coat of the uterus appears on MRI images, and in which carcinoma with specific histology (e.g., serous adenocarcinoma) or anaplastic endometrioid adenocarcinoma is seen. Semi-radical hysterectomy and pelvic lymphadenectomy have been considered to be indicated in all other cases. Adjuvant chemotherapy and radiotherapy after surgery has been indicated for cases in which invasion of the muscle coat of the uterus is to a depth of more than half its thickness, stromal invasion of the cervix is seen, or invasion of the serosa or metastasis to the uterine adnexae or lymph nodes is seen. Patients were externally irradiated with a dose of 50 Gy to the whole pelvis as adjuvant radiotherapy. The follow-up period ranged from 4 to 148 months. Of the 147 cases, 105 (71.4%) were treated by hysterectomy alone and the other 42 received adjuvant therapy (chemotherapy in 27 cases, radiotherapy in 15 cases). All stage Ia patients (16 cases) survived, and none were given additional therapy. Only 4.8% of the stage Ib cases (62) and 7.1% of the stage 2a cases (14) received adjuvant therapy, and no recurrences

    To describe the sonohysterographic findings of endometrial abnormalities, and to determine the usefulness of sonohysterography (SH) for predicting endometrial abnormalities in women with polycystic ovarian disease(PCOD). 82 patients with PCOD who had vaginal bleeding or endometrial thickening and lesion mass on baseline transvaginal sonography were prospectively examined with SH. The SH findings were evaluated for endometrial thickness, the presence of endometrial thickening and lesion mass, echogenicity and surface contour, distensibility of the endometrial cavity, and disruption of endometrial-myometrial interface. These findings were compared with the pathologic findings and the diagnostic accuracy of SH for predicting endometrial abnormalities was assessed. Endometrial abnormalities were identified in 47 (57.3%) of 82 PCOD patients, and their pathologic diagnosis included endometrial carcinoma in 7 cases, hyperplasia in 19 cases (atypical hyperplasia, n=5), and polyp in 21 cases. Of the 35 patients who did not have endometrial abnormalities, there was disordered proliferative endometrium in 18 cases and normal proliferative or secretory endometrium in 17 cases. The SH findings of endometrial carcinoma were endometrial thickening in 5 cases, endometrial thickening and lesion mass in 2 cases, and the endometrial thickness ranged from 6 mm to 15 mm (mean 9.5 mm). They were characterized as a diffuse polyploid endometrial thickening or a sessile endometrial mass with irregular surface, homogeneous hyperechogenicity, and obliteration of the endometrial cavity. Endometrial hyperplasia appeared as endometrial thickening in 14 cases, endometrial lesion mass in 3 cases, and endometrial thickening and lesion mass in 2 cases, and the endometrial thickness was between 6.5-10.7 mm (mean 8.2 mm). They showed a diffuse uniform endometrial thickening or a polyploid endometrial lesion mass with homogeneous hyperechogenicity and a regular surface. Endometrial polyps appeared as

  19. Mechanisms of trophoblast migration, endometrial angiogenesis in preeclampsia: The role of decorin.

    Lala, Peeyush K; Nandi, Pinki

    2016-03-01

    The objective of the present review is to synthesize the information on the cellular and molecular players responsible for maintaining a homeostatic balance between a naturally invasive human placenta and the maternal uterus in pregnancy; to review the roles of decorin (DCN) as a molecular player in this homeostasis; to list the common maladies associated with a break-down in this homeostasis, resulting from a hypo-invasive or hyper-invasive placenta, and their underlying mechanisms. We show that both the fetal components of the placenta, represented primarily by the extravillous trophoblast, and the maternal component represented primarily by the decidual tissue and the endometrial arterioles, participate actively in this balance. We discuss the process of uterine angiogenesis in the context of uterine arterial changes during normal pregnancy and preeclampsia. We compare and contrast trophoblast growth and invasion with the processes involved in tumorigenesis with special emphasis on the roles of DCN and raise important questions that remain to be addressed. Decorin (DCN) is a small leucine-rich proteoglycan produced by stromal cells, including dermal fibroblasts, chondrocytes, chorionic villus mesenchymal cells and decidual cells of the pregnant endometrium. It contains a 40 kDa protein core having 10 leucine-rich repeats covalently linked with a glycosaminoglycan chain. Biological functions of DCN include: collagen assembly, myogenesis, tissue repair and regulation of cell adhesion and migration by binding to ECM molecules or antagonising multiple tyrosine kinase receptors (TKR) including EGFR, IGF-IR, HGFR and VEGFR-2. DCN restrains angiogenesis by binding to thrombospondin-1, TGFβ, VEGFR-2 and possibly IGF-IR. DCN can halt tumor growth by antagonising oncogenic TKRs and restraining angiogenesis. DCN actions at the fetal-maternal interface include restraint of trophoblast migration, invasion and uterine angiogenesis. We demonstrate that DCN overexpression in

    2010-02-15

    Objective: The aim of the present study is to determine long-term clinical efficacy of uterine fibroid embolization (UFE) for symptomatic fibroids in conjunction with MR evaluation. Materials and methods: Sixteen patients with a follow-up period of 4 years or longer were analyzed retrospectively. Ages ranged from 27 to 45 (mean 39.5) years. Mean follow-up periods were 5.8 years (range: 4.1-6.9 years). The symptom changes, in terms of menorrhagia and dysmenorrhea and bulk-related symptoms, were assessed. The primary embolic agent was polyvinyl alcohol particle (250-710 {mu}m). All patients underwent preprocedural and long-term follow up MR imaging. Uterine volumes were calculated using MRI. Results: Symptom improvements were reported for menorrhagia (8/9, 88.9%), dysmenorrhea (5/5, 100%), and bulk-related symptoms (7/9, 77.8%) at long-term follow up. Two patients (12.5%) had symptom recurrences at long-term follow-up. Tumor regrowth from incomplete infarction was a cause of recurrence in one patient and newly developed leiomyomas in the other one. One patient underwent hysterectomy because endometriosis developed 4 years after UFE. Of the 14 necrotic myomas on short-term follow up MR after UFE, eight (57.1%) demonstrated maintaining necrosis with further shrinkage and six (42.9%) were no longer visualized on long-term follow up MR images. Overall, the mean volume reduction rates of the predominant fibroid and uterus were 80.5%, 36.7% at long-term follow up, respectively. Conclusion: UFE is an effective treatment for symptomatic fibroids with an acceptable long-term success rate. Long-term MR imaging after UFE revealed persistent necrotic fibroid, non-visualization of fibroids and tumor regrowth when incompletely infarcted.

    Secretory leukocyte protease inhibitor (SLPI) is a serine protease inhibitor that diminishes tissue destruction during inflammation. A recent report revealed high levels of SLPI expression in the oral carcinoma cell. In addition, overexpression of SLPI up-regulates metastasis in lung carcinoma cells. On the other hand, matrix metalloproteinases (MMPs) are proteinases that participate in extracellular matrix degradation. SLPI and MMPs are involved as accelerators of the tumor invasion process; however, their exact roles are not fully understood. Understanding the mechanism of tumor invasion requires models that take the effect of microenvironmental factors into account. In one such in vitro model, different carcinoma cells have been shown to invade myoma tissue in highly distinct patterns. We have used this myoma model, as it provides a more natural stroma-like environment, to investigate the role of SLPI in tumor invasion. Our results indicate that the model provides a relevant matrix for tumor invasion studies, and that SLPI is important for the invasion of oral carcinoma Ca9-22 cells in conjunction with MMPs. Furthermore, using bioinformatics analysis, we have identified candidates as key molecules involved in SLPI-mediated tumor invasion. PMID:27238568

  10. Uterine transplantation: a promising surrogate to surrogacy?

    Grynberg, Michael; Ayoubi, Jean-Marc; Bulletti, Carlo; Frydman, Rene; Fanchin, Renato

    2011-03-01

    Infertility due to the inability of the uterus to carry a pregnancy ranks among the most unresolved issues in reproductive medicine. It affects millions of women worldwide who have congenital or acquired uterine affections, often requiring hysterectomy, and potentially represents a considerable fraction of the general infertile population. Patients suffering from severe uterine infertility are currently compelled to go through gestational surrogacy or adoption; both approaches, unfortunately, deprive them of the maternal experience of pregnancy and birth. Uterine transplantation represents an outstanding, yet complex, perspective to alleviating definitive uterine infertility. In the past decades, a number of scientific experiments conducted both in animals and women, focusing on uterine transplantation, have led to promising results. Collectively, these findings undoubtedly constitute a sound basis to clinically apply uterine transplantation in the near future. This paper is, however, an overview not only of the extent and limitations of accumulated scientific knowledge on uterine transplantation, but also its ethical implications, in an effort to define the actual place of such an approach among the therapeutic arsenal for alleviating infertility.

    2013-10-01

    Endometritis is an important cause of sub-fertility in mares. The critical indicator of reproductive success and financial return for commercial studs is live foaling rate. Endometrial bacteriology and/or cytology are used to diagnose endometritis and thus identify mares at risk of early embryonic death. However, mares with endometritis may conceive but then abort in late gestation. The aims of this study were to establish, as part of a standard breeding examination (1) whether a threshold percentage of uterine polymorphonuclear neutrophils (PMNs) exists above which a significant reduction in live foaling rate is evident; (2) the relationship of a positive bacteriology result to live foaling rate, and (3) the relationship of a combination of positive cytology and bacteriology result to live foaling rate. Guarded endometrial swabs (n=2660) were collected from 1621 Thoroughbred mares on 17 commercial stud farms by five veterinarians during a single breeding season. All mares were included regardless of age, history or parity. Cytological and bacteriological analyses were performed on each swab and subsequent live foaling rates recoded. Data were analysed by comparing 0%, ≥ 1%, ≥ 2%, ≥ 5% or ≥ 25% PMNs of total cells counted, or categories of bacterial growth to live foaling rates, using Pearson's chi-squared test. A threshold value of ≥ 1% PMNs, culture of a single bacterial isolate and a combination of both these parameters were associated with significantly reduced live foaling rates. Positive cytology alone, positive bacterial culture alone, or combined positive cytology and bacteriology were equally indicative of the likelihood of a mare producing a live foal. PMID:24035467

  13. Hypoxia Promotes Invasion of Endometrial Stromal Cells via Hypoxia-Inducible Factor 1α Upregulation-Mediated β-Catenin Activation in Endometriosis.

    Endometriosis is a common benign gynecological disease defined as the presence of endometrial tissue outside the uterine cavity. The aim of this study was to identify the molecular mechanism underlying hypoxia-induced increases in invasive ability of human endometrial stromal cells (HESCs). Herein, we show that the expression levels of hypoxia-inducible factor lα (HIF-1α) and β-catenin were greater in ectopic endometriotic tissue compared with eutopic tissue from controls. Exposure of eutopic endometrial stromal cells under hypoxic conditions or treated with desferrioxamine (DFO, chemical hypoxia) resulted in a time-dependent increase in β-catenin expression and its dephosphorylation. Hypoxia/HIF-1α also activated the β-catenin/T-cell factor (TCF) signaling pathway and the expression of target genes, vascular endothelial growth factor and matrix metalloproteinase 9, and knockdown of HIF-1α or β-catenin abrogated hypoxia-induced increases in HESC invasiveness. These results suggest that HIF-1α interacting with β-catenin/TCF signaling pathway, which is activated by hypoxia, may provide new insights into the etiology of endometriosis. PMID:26482209

  14. Ancient Transposable Elements Transformed the Uterine Regulatory Landscape and Transcriptome during the Evolution of Mammalian Pregnancy

    2015-02-01

    Full Text Available A major challenge in biology is determining how evolutionarily novel characters originate; however, mechanistic explanations for the origin of new characters are almost completely unknown. The evolution of pregnancy is an excellent system in which to study the origin of novelties because mammals preserve stages in the transition from egg laying to live birth. To determine the molecular bases of this transition, we characterized the pregnant/gravid uterine transcriptome from tetrapods to trace the evolutionary history of uterine gene expression. We show that thousands of genes evolved endometrial expression during the origins of mammalian pregnancy, including genes that mediate maternal-fetal communication and immunotolerance. Furthermore, thousands of cis-regulatory elements that mediate decidualization and cell-type identity in decidualized stromal cells are derived from ancient mammalian transposable elements (TEs. Our results indicate that one of the defining mammalian novelties evolved from DNA sequences derived from ancient mammalian TEs co-opted into hormone-responsive regulatory elements distributed throughout the genome.

  15. Risk factors of distant metastasis in patients with squamous cell carcinoma of the uterine cervix treated with postoperative irradiation

    This paper reports the results of a study of risk factors for recurrence in non-irradiated sites in patients with squamous cell carcinoma of the uterine cervix who received postoperative irradiation. It also discusses clinical experience with such patients, particularly those with a poor prognosis, based on a review of the literature. The study was conducted at the National Shikoku Cancer Center in 62 patients with squamous cell carcinoma of the uterine cervix (mean age=50.5, range=30-66) who received 10 MeV postoperative irradiation with a Linac between 1981 and 1990. An analysis was performed in terms of sites and times of recurrence, risk factors for distant metastasis, and groups at high risk for distant metastasis. Based on the results of the study as well as the review of the literature, it was concluded that squamous cell carcinoma of the uterine cervix is sensitive to radiation therapy and that the clinical outcome of local treatment is satisfactory. However, systemic chemotherapy should be considered for patients who are suspected of having minute distant metastasis at the time of surgical operation, i.e., those with moderate to severe vascular space invasion, multiple lymph node metastasis, parametrium infiltration, and/or endometrial infiltration.

    Childbearing at an older age has been associated with a lower risk of endometrial cancer, but whether the association is independent of the number of births or other factors remains unclear. Individual-level data from 4 cohort and 13 case-control studies in the Epidemiology of Endometrial Cancer Consortium were pooled. A total of 8,671 cases of endometrial cancer and 16,562 controls were included in the analysis. After adjustment for known risk factors, endometrial cancer risk declined with increasing age at last birth (P(trend) late age at last birth was independently associated with a reduced risk of endometrial cancer, and the reduced risk persisted for many years.

    Uterine fibroids are the most common benign female tumours during reproductive age. The traditional treatment for this condition is typically hysterectomy. However, there are new technologies on the rise, such as Uterine Artery Embolisation and Magnetic Resonance-guided Focused Ultrasound which are directed towards a minimally invasive or even noninvasive treatment of uterine fibroids. These modern procedures allow for a fast recovery and preservation of fertility. In this work, we presented these alternative procedures and highlighted their and limitations. (authors)

    Chemokines play a central role in cellular communication in response to bacterial infection. However, the knowledge of the chemokine responses to bacterial infections in dogs remains limited. Uterine bacterial infection (pyometra) is one of the most common bacterial diseases in dogs and causes sepsis in most of the cases. We have shown previously that dogs with pyometra have higher messenger RNA (mRNA) levels of chemokines in uterus. To assess whether the stromal part of the endometrium expresses chemokines in response to bacterial infection, we cultured endometrial stromal cells isolated from healthy dogs and exposed them to either live pathogenic Escherichia coli, isolated from the uterus of a dog with pyometra, or lipopolysaccharide. Changes in the mRNA expression of ELR(+) CXC chemokines, IL-8, CXCL5, CXCL7, and ELR(-) CXC chemokine, CXCL10, were measured after 24 hours using quantitative real-time polymerase chain reaction. Levels of IL-8, CXCL5, and CXCL10 were upregulated in endometrial stromal cells exposed to E coli and lipopolysaccharide, whereas the level of CXCL7 was decreased or unaffected. In addition, levels of IL-8 and CXCL5, but not CXCL7 or CXCL10, were significantly higher in dogs with pyometra than those in healthy dogs. Our findings show that pathogenic uterine-derived E coli induces a CXC chemokine response both in cultured endometrial stromal cells within 24 hours and in pyometra-affected uteri from dogs. Stromal cells could therefore play an important role in early neutrophil and T cell recruitment to the site of inflammation during gram-negative bacterial infection of the uterus. Further studies are needed to clarify the role of chemokines in host response to bacterial infection in dogs and the possibility of using chemokines as diagnostic parameters for bacterial infection in this species.

    2015-12-01

    Interactions between the highly invasive trophoblasts and the maternal uterine decidual extracellular matrix (ECM) are crucial in the determination of a successful pregnancy. Fibulin-5 (FBLN5) is a member of the fibulin family that alters cell adhesive and invasive properties and is expressed in human villous cytotrophoblasts. We aimed to determine the expression and immunolocalization of FBLN5 in human first trimester decidua and examine the effect of FBLN5 in trophoblast invasion in vitro using a first trimester placental villous outgrowth assay. We demonstrated that FBLN5 mRNA expression is upregulated in response to cAMP-mediated decidualization of primary human endometrial stromal cells, although FBLN5 itself does not enhance decidualization. We reported for the first time, FBLN5 protein production in first trimester decidual cells and also co-localization to HLAG-positive EVTs in first trimester decidua. Consequently, we investigated the effects of exogenous FBLN5 on placental villous outgrowth in vitro and demonstrated that FBLN5 promotes EVT migration/invasion. This is the first study to identify FBLN5 in decidualized human endometrial stromal cells, first trimester decidua and EVT and determine a functional role for FBLN5 in human EVTs, suggesting that decidual and or EVT-derived FBLN5 regulates EVT invasion and placentation in women.

    From 1991 to 1995, 71 patients with endometrial cancer at Okayama University Medical School underwent transvaginal ultrasonography with a 6.5-MHz transducer, MRI at 1.5 T, and hysteroscopy using a rigid hysteroscope. The findings of these examinations were compared against pathologic results. The sensitivity/specificity/accuracy were 0.73/0.89/0.86 for transvaginal ultrasonography, 0.73/0.88/0.85 for MRI, and 0.73/0.80/0.79 for hysteroscopy. The coefficient values for transvaginal ultrasonography/MRI/hysteroscopy were 0.69/0.62/-0.21 and 1.99/1.89/0.79 in quantification theory second family analysis and logistic regression, respectively. Misdiagnosed cases had the following factors: large tumor volume; tumor near the internal os; tumor descending from the uterine cavity; polypoid tumor in the endocervix; artifacts due to the use of a cervix dilator made from stems of the seaweed Laminaria japonica; endocervical glandular involvement only; and atypical signals on MRI. For the preoperative assessment of cervical invasion, transvaginal ultrasonography and MRI were the most reliable. Hysteroscopy was least reliable, because of a large number of false-positive results. The use of these examinations in combination, especially transvaginal ultrasonography and MRI, would be of great value in surgical planning for endometrial cancer, considering the factors responsible for misdiagnosis.

    Mitogen inducible gene 6 (Mig-6) is an important mediator of progesterone (P4) signaling to inhibit estrogen (E2) signaling in the uterus. Ablation of Mig-6 in the murine uterus leads to the development of endometrial hyperplasia and E2-induced endometrial cancer. To identify the molecular pathways regulated by Mig-6, we performed microarray analysis on the uterus of ovariectomized Mig-6{sup f/f} and PGR{sup cre/+}Mig-6{sup f/f} (Mig-6{sup d/d}) mice treated with vehicle or P4 for 6 h. The results revealed that 772 transcripts were significantly regulated in the Mig-6{sup d/d} uterus treated with vehicle as compared with Mig-6{sup f/f} mice. The pathway analysis showed that Mig-6 suppressed the expression of gene-related cell cycle regulation in the absence of ovarian steroid hormone. The epithelium of Mig-6{sup d/d} mice showed a significant increase in the number of proliferative cells compared to Mig-6{sup f/f} mice. This microarray analysis also revealed that 324 genes are regulated by P4 as well as Mig-6. Cited2, the developmentally important transcription factor, was identified as being regulated by the P4-Mig-6 axis. To determine the role of Cited2 in the uterus, we used the mice with Cited2 that were conditionally ablated in progesterone receptor-positive cells (PGR{sup cre/+}Cited2{sup f/f}; Cited2{sup d/d}). Ablation of Cited2 in the uterus resulted in a significant reduction in the ability of the uterus to undergo a hormonally induced decidual reaction. Identification and analysis of these responsive genes will help define the role of P4 as well as Mig-6 in regulating uterine biology. - Highlights: • We identify Mig-6- and P4-regulated uterine genes by microarray analysis. • Mig-6 suppresses cell cycle progression and epithelial cell proliferation in uterus. • We identify the Mig-6 dependent induced genes by P4. • Cited2 plays an important role for decidualization as a P4 and Mig-6 target gene.

    Normal pregnancy involves dramatic remodeling of the uterine vasculature, with abnormal vascular adaptations contributing to pregnancy diseases such as preeclampsia. The peptide hormone relaxin is important for the renal and systemic hemodynamic adaptations to pregnancy, and has been shown to increase arterial compliance and outward hypertrophic remodeling. Therefore, we investigated the possibility that relaxin acts on its receptor, RXFP1, to mediate uterine artery compliance in late pregnancy and increase uterine blood flow velocity in rats. RXFP1 was predominantly localized to the tunica media vascular smooth muscle cells in the uterine artery, although receptors were also detected in endothelial cells. Highest expression of Rxfp1 in the uterine artery occurred in estrus and early pregnancy. Isolated uterine arteries from late pregnant rats treated with a monoclonal antibody against circulating relaxin (MCA1) had significantly increased vessel wall stiffness compared with controls, with no reduction in wall thickness. Chronic infusion of relaxin (4 μg/h, osmotic minipump) for 5 d in nonpregnant rats significantly increased uterine artery blood flow velocity. Overall, these data demonstrate a functional role for relaxin in mediating uterine artery compliance in pregnant rats, which may be necessary to maintain adequate uterine blood flow to the uterus and placenta.

    To evaluate the usefulness of three dimensional sonohysterography (3D SHG) in the evaluation of uterine endometrial and submucosal lesions in comparison with conventional two-dimensional sonohysterography (2D SHG). Our series consisted of 26 patients (mean aged 41 years) who complained of uterine bleeding, menorrhagia, or dysmenorrhea. 2D SHG was performed, and then 3D SHG was done after the volume mode was switched on. Simultaneous display of three perpendicular two-dimensional planes and surface rendering of findings on particular section were obtained. We analyzed whether the endometrium was thickened or not, and the location, size, shape, echogenicity, posterior shadowing, and echogenic rim of the focal lesion. The results were compared with the pathologic findings or MRI. There were submucosal myomas (n=12), intramural myomas (n=2), endometrial polyps (n=7), placental polyp (n=1), and normal endometrial cavities (n=4) on SHG. Nineteen cases were confirmed by pathologic findings or MRI. The results were correlated in 89% (17/19) of the cases. We misdiagnosed 2 cases: focal endometrial hyperplasia and choriocarcinoma were misdiagnosed as endometrial polyp and placental polyp, respectively. Imaging diagnoses were same in the techniques. Comparing with 2D SHG, 3D SHG provided a subjective display of pathologic findings and an additional information about spatial relationship between focal lesion and surroundings.

  8. High dose rate brachytherapy for medically inoperable stage I endometrial cancer

    Purpose/Objective: To determine the efficacy of high dose rate (HDR) brachytherapy in patients with medically inoperable endometrial cancer clinically confined to the corpus. Materials and Methods: Forty-two patients with endometrial cancer and an intact uterus have been treated since 1989 with HDR brachytherapy. Twenty-six patients with medically inoperable Stage I disease were treated with radiation alone and form the basis of this study. Obesity was assessed using the body mass index (BMI kg/m2) scale. Patients with a BMI above 28 were considered obese and those above 35 morbidly obese, per standard anesthesia guidelines. Brachytherapy was delivered in 5 HDR insertions, 1 week apart, without any external beam radiation. The following doses were delivered per insertion: 5.7 Gy to point S, 7.0 Gy to point W, 8.2 Gy to the vaginal surface and 9.2 Gy to point M. Point M represents the conventional point A dose, while points S and W are myometrial points. A single tandem with either ovoids or cylinders was placed, unless the uterine cavity would accommodate 2 tandems. All treatments were outpatient using intravenous fentanyl and midazolam for sedation. Pelvic ultrasound was commonly used at the time of brachytherapy to verify tandem placement. Three year clinical endpoints were calculated using the Kaplan Meier method. Results: The median follow-up for the study cohort was 21 months with follow-up greater than 36 months in 11 patients. Seventeen of the 26 patients were inoperable due to morbid obesity (median weight and BMI; 316 lbs and 55 kg/m2, respectively); the other patients had poor cardiopulmonary reserve ± obesity. The median age, KPS (Karnofsky Performance Status), weight, ASA (American Society of Anesthesiologists' Physical Class System) and BMI were 63 yrs, 80%, 285 lbs, 3 and 49 kg/m2, respectively. Two patients with an ASA of 3 and 4 died from acute cardio-pulmonary events within 30 days of the last insertion, emphasizing the need for accurate pre

    Sub-endometrial junctional zone peristalsis is increased by ovarian stimulation and traumatic embryo transfer, and is linked with decreased implantation and pregnancy rates in assisted reproduction treatments. Various agents have been used to inhibit uterine hyper-peristalsis at the time of embryo transfer with conflicting results. This systematic review aimed to identify if uterine relaxants administered in the peri-implantation period during assisted reproduction treatments could improve pregnancy outcomes through literature search with no language restrictions. The review reports on 3546 patients in 17 randomized controlled trials published between 1993 and 2014. Women undergoing assisted reproduction techniques who either received a uterine relaxant agent in the peri-implantation period versus placebo or no treatment were included. Primary outcome was live birth rate. The meta-analyses did not show statistically significant benefit of any uterine relaxing agents on live birth rate. Other meta-analyses did not show a significant effect on the clinical pregnancy, spontaneous abortion, ectopic pregnancy and multiple pregnancy rate. Most of the included studies were of low quality and lacked significant power to detect minimally important effect. Evidence is insufficient to recommend using these agents in routine practice. Further methodologically robust randomized controlled trials with more refined selection criteria might reveal a beneficial effect. PMID:26936145

  11. Uterine Healing after Therapeutic Intrauterine Administration of TachoSil (Hemostatic Fleece in Cesarean Section with Postpartum Hemorrhage Caused by Placenta Previa

    2012-01-01

    Full Text Available Background. Application of hemostatic fleece (TachoSil directly onto the bleeding surfaces of the lower uterine segment has been used to obtain hemostasis during cesarean section caused by placenta previa. Methods. Eleven of 15 patients treated with TachoSil for excessive postpartum haemorrhage due to placenta previa were enrolled. An evaluation of the cesarean section scar by transvaginal ultrasound, the uterine cavity and endometrium by hysteroscopy, and the endometrium by biopsy were made. The main outcome measures were intrauterine adhesions, recovery of endometrium at the site of TachoSil application, visible remnants of TachoSil, and scar healing. Results. Eight patients had small remnants of TachoSil in the uterine cavity together with signs of resorption. All had a normal endometrial mucosa, and none had adhesions in the uterine cavity. All cesarean section scars were healed without defects. Conclusion. TachoSil did not seem to impair healing of the endometrium or scar formation in the uterus after intrauterine application. Resorption of TachoSil seems to progress individually. Intrauterine treatment with TachoSil is a valuable supplement to the traditional treatment of post partum haemorrhage and may help retain reproductive capability. This is a small study, and it will require more studies to confirm the reproducibility.

    Results of this study showed that the bacterial composition in vagina (V) greatly differed from intrauterine microbiome (I). Microbiomes were present in all intrauterine samples of healthy women (Group H (I)) and patients with endometrial polyps (EP) (including Group EP (I) and Group EP/chronic endometritis (CE) (I)). Indeed, the intrauterine bacteria population in Group EP/CE (I) were more diverse than those in Groups EP (I) and H (I). The result also confirmed the bacterial composition differences between vagina and uterus as well as the intrauterine microbiome alteration in the patients, compared to the healthy. Although bacteria of Proteobacteria, Firmicutes and Actinobacteria, dominated the intrauterine microbiome in all samples, however, proportions of Firmicutes from Group EP/CE (I) and Group EP (I) were much higher than that from Group H (I), in contrast, the proportions of Proteobacteria were far lower than the healthy. At the genus level, compared to Group H (I), it is found that proportions of Lactobacillus, Gardnerella, Bifidobacterium, Streptococcus, and Alteromonas were significantly higher, and that of Pseudomonas were significantly lower in Group EP/CE (I) or Group EP (I). In addition, lower proportions of Enterobacter and Sphingomonas and a higher proportion of Prevotella were also observed in Group EP/CE (I). In conclusion, uterine microbiomes between patients with EP and the healthy are significantly different and all the potentially important variation of uterine microbes may cause EP, but not definitively related to CE. Further experiments should be performed to test these relationships to endometritis occurrence. PMID:27186283

  13. Differential analysis of ovarian and endometrial cancers identifies a methylator phenotype.

    Diana L Kolbe

    Full Text Available Despite improved outcomes in the past 30 years, less than half of all women diagnosed with epithelial ovarian cancer live five years beyond their diagnosis. Although typically treated as a single disease, epithelial ovarian cancer includes several distinct histological subtypes, such as papillary serous and endometrioid carcinomas. To address whether the morphological differences seen in these carcinomas represent distinct characteristics at the molecular level we analyzed DNA methylation patterns in 11 papillary serous tumors, 9 endometrioid ovarian tumors, 4 normal fallopian tube samples and 6 normal endometrial tissues, plus 8 normal fallopian tube and 4 serous samples from TCGA. For comparison within the endometrioid subtype we added 6 primary uterine endometrioid tumors and 5 endometrioid metastases from uterus to ovary. Data was obtained from 27,578 CpG dinucleotides occurring in or near promoter regions of 14,495 genes. We identified 36 locations with significant increases or decreases in methylation in comparisons of serous tumors and normal fallopian tube samples. Moreover, unsupervised clustering techniques applied to all samples showed three major profiles comprising mostly normal samples, serous tumors, and endometrioid tumors including ovarian, uterine and metastatic origins. The clustering analysis identified 60 differentially methylated sites between the serous group and the normal group. An unrelated set of 25 serous tumors validated the reproducibility of the methylation patterns. In contrast, >1,000 genes were differentially methylated between endometrioid tumors and normal samples. This finding is consistent with a generalized regulatory disruption caused by a methylator phenotype. Through DNA methylation analyses we have identified genes with known roles in ovarian carcinoma etiology, whereas pathway analyses provided biological insight to the role of novel genes. Our finding of differences between serous and endometrioid

    Squamous cell carcinoma (SCC) of the endometrium, whether primary or secondary to cervical cancer, is a rare entity. Primary endometrial squamous cell carcinoma in situ is even more uncommon; it usually occurs in postmenopausal women and has a strong association with pyometra. We report a 60-year-old multiparous postmenopausal woman who presented to the Hakeem Abdul Hameed Centenary Hospital, New Delhi, India, in May 2014 with a lower abdominal swelling corresponding in size to a pregnancy of 26 gestational weeks and vaginal discharge of one year’s duration. A total abdominal hysterectomy with a bilateral salpingooophorectomy was performed, which revealed an enlarged uterus with pyometra. Histopathology showed that the entire endometrial lining had been replaced with malignant squamous cells without invasion of the myometrium. Immunohistochemistry revealed that the tumour cells were positive for p63 with a high Ki-67 labelling index. No adjuvant therapy was required and the patient was disease-free at a seven-month follow-up. PMID:26629388

    Full Text Available Abstract Background The endometrium is a dynamic tissue whose changes are driven by the ovarian steroidal hormones. Its main function is to provide an adequate substrate for embryo implantation. Using microarray technology, several reports have provided the gene expression patterns of human endometrial tissue during the window of implantation. However it is required that biological connections be made across these genomic datasets to take full advantage of them. The objective of this work was to perform a research synthesis of available gene expression profiles related to acquisition of endometrial receptivity for embryo implantation, in order to gain insights into its molecular basis and regulation. Methods Gene expression datasets were intersected to determine a consensus endometrial receptivity transcript list (CERTL. For this cluster of genes we determined their functional annotations using available web-based databases. In addition, promoter sequences were analyzed to identify putative transcription factor binding sites using bioinformatics tools and determined over-represented features. Results We found 40 up- and 21 down-regulated transcripts in the CERTL. Those more consistently increased were C4BPA, SPP1, APOD, CD55, CFD, CLDN4, DKK1, ID4, IL15 and MAP3K5 whereas the more consistently decreased were OLFM1, CCNB1, CRABP2, EDN3, FGFR1, MSX1 and MSX2. Functional annotation of CERTL showed it was enriched with transcripts related to the immune response, complement activation and cell cycle regulation. Promoter sequence analysis of genes revealed that DNA binding sites for E47, E2F1 and SREBP1 transcription factors were the most consistently over-represented and in both up- and down-regulated genes during the window of implantation. Conclusions Our research synthesis allowed organizing and mining high throughput data to explore endometrial receptivity and focus future research efforts on specific genes and pathways.

    Conclusions: Postmenopausal bleeding, should always be taken seriously, no matter how minimal or nonpersistent it is, because though majority of causes underlying postmenopausal bleeding are benign, endometrial carcinoma may be seen in around 10% cases. So, patients with PMB must undergo thorough evaluation by endometrial sampling which cannot be replaced by transvaginal sonography which though has more sensitivity to detect endometrial thickening, at the same time, has low specificity for detection of malignancy.

  19. Uterine Artery Embolization to Treat Uterine Adenomyosis with or without Uterine Leiomyomata: Results of Symptom Control and Health-Related Quality of Life 40 Months after Treatment

    Purpose: To evaluate the clinical outcome for uterine adenomyosis with or without uterine leiomyomata 40 months after uterine artery embolization (UAE). Methods: Forty women aged 39–56 years (median 46 years) with symptomatic uterine adenomyosis and magnetic resonance imaging findings of uterine adenomyosis with or without combined uterine leiomyomata underwent UAE. Self-perceived changes in clinical symptoms were assessed, and residual symptom severity and health-related quality of life (HRQOL) after UAE were evaluated. Clinical failure was defined as no symptomatic improvement or second invasive therapy after UAE. Results were stratified by the extent of uterine adenomyosis at baseline magnetic resonance imaging. Results: Patients were followed for a median of 40 months (range 5–102 months). UAE led to symptomatic control after UAE in 29 (72.5%) of 40 patients while 11 women underwent hysterectomy (n = 10) or dilatation and curettage (n = 1) for therapy failure. No significant difference between women with pure uterine adenoymosis and women with uterine adenomyosis combined with uterine leiomyomata was observed. Best results were shown for UAE in uterine adenomyosis with uterine leiomyomata predominance as opposed to predominant uterine adenomyosis with minor fibroid disease (clinical failure 0% vs. 31.5%, P = 0.058). Throughout the study group, HRQOL score values increased and symptom severity scores decreased after UAE. Least improvement was noted for women with pure adenomyosis. Conclusions: UAE is clinically effective in the long term in most women with uterine adenomyosis. Symptomatic control and HRQOL were highest in patients with combined disease of uterine adenomyosis but leiomyomata predominance.

    Embryo implantation is an essential step for the establishment of pregnancy and dynamically regulated by estrogen and progesterone. NDRG4 (N-myc down-regulated gene 4) is a tumor suppressor that participates in cell survival, tumor invasion and angiogenesis. The objective of this study was to preliminarily explore the role of NDRG4 in embryo implantation. By immunohistochemistry (IHC) and quantitive RT-PCR (qRT-PCR), we found that uterine expression of NDRG4 was increased along with puberal development, and its expression in adult females reached the peak at the estrus stage during the estrus cycle. Furthermore, uterine NDRG4 expression was significantly induced by the treatment of estradiol (E2) both in pre-puberty females and ovariectomized adult females. Uterine expression pattern of NDRG4 during the peri-implantation period in mice was determined by IHC, qRT-PCR and Western blot. It was observed that NDRG4 expression was up-regulated during the implantation process, and its expression level at the implantation sites was significantly higher than that at the inter-implantation sites. Meanwhile, an increased expression in NDRG4 was associated with artificial decidualization as well as the activation of delayed implantation. By qRT-PCR and Western blot, we found that the in vitro decidualization of endometrial stromal cells (ESCs) was accompanied by up-regulation of NDRG4 expression, whereas knockdown of its expression in these cells by siRNA inhibited the decidualization process. In addition, Western blot analysis showed that NDRG4 protein expression was decreased in human villus tissues of recurrent miscarriage (RM) patients compared to normal pregnant women. Collectively, these data suggested that uterine NDRG4 expression could be induced by estrogen, and NDRG4 might play an important role during early pregnancy. PMID:27175791
