    Objective: To analyse the clinical characteristics of patients with uterus effusion after irradiation for carcinoma of the cervix. Methods: 151 patients with uterus effusion after irradiation for carcinoma of the cervix were retrospectively analyzed. Results: All these 151 patients who had been treated by radiotherapy had FIGO stage IIB or IIIB lesions including 32 adenocarcinomas. The most common symptom was irregular vaginal discharge or drainage (65 patients), followed by irregular vaginal bleeding (32 patients), and abdominal or pelvic mass (27 patients). Twenty-seven patients were entirely asymptomatic. The positive rate of uterus effusion found by B-ultrasound scan was 100%. When uterus effusion was found, 87 patients (57.6%) had malignant tumor, including 62 with residual or recurrent cervical carcinoma and 25 with secondary primary malignant uterus tumor. Sixty-four patients had uterus effusion alone including 8 with pyometra. Of these 64 patients, 17 underwent abdominal hysterectomy with bilateral salpingo-oophorectomy (BSOH), the others were treated with drainage till the fluid disappeared. Of the 62 patients with residual or recurrent cervical carcinoma, 19 underwent BSOH and 43 were treated by palliative irradiation or chemotherapy. Twenty-five patients who had secondary primary malignant uterus tumor were treated by BSOH. The 5-year survival rate of patients with uterus effusion alone, with residual tumor (with recurrent tumor), or with secondary primary malignancy were 54.8%, 0%, 28.7% and 47.5%, respectively. The prognosis of the patients with uterus effusion alone was better than those with secondary primary malignant uterus tumor. Patients with residual or recurrent cervical cancer had the worst prognosis. Conclusions: Patients with uterus effusion after irradiation for carcinoma of the cervix often have tumor including secondary primary, malignant uterus tumor. The prognosis is different, which depends on if the patient has tumor or not. (authors)

    Relaxin is a member of the insulin family of polypeptide hormones and is known to exert its biological effects on various parts of the mammalian reproductive system. Biologically active human relaxin has been chemically synthesized based on the nucleotide sequence obtained from an ovarian cDNA clone. In the present study synthetic human relaxin was radiolabled by phosphorylation with cAMP-dependent protein kinase and [gamma-32P]ATP to a specific activity of 5000 Ci/mmol. The phosphorylated relaxin was purified on cation exchange high performance liquid chromatography and was shown to co-migrate with relaxin on sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Mass spectrometry revealed a single phosphorylated site on the B chain of relaxin. The 32P-relaxin was able to bind to a goat anti-relaxin antibody, and this binding could be displaced by unlabeled relaxin in a concentration-dependent manner. A comparison of the concentration responses of cellular cAMP production stimulated by relaxin and phosphorylated relaxin in a primary human uterine cell line showed that phosphorylation did not affect the in vitro biological efficacy of relaxin. This made it suitable for in situ autoradiographic localization of relaxin binding sites in rat uterine, cervical, and brain tissue sections. Displacement of the binding of 100 pM 32P-relaxin by 100, 10, and 3 nM unlabeled relaxin, but not by 100 nM insulin, insulin-like growth factor-I, and an insulin-like growth factor-I analog, demonstrated the high affinity and specificity of such binding. We conclude that 32P-labeled human relaxin is biologically and immunologically active and that this novel probe binds reversibly and with high affinity to classical (e.g. uterus) and unpredicted (e.g. brain) tissues

    The purpose of this study was to establish normal values for the volume of the uterus and cervix in MRI based on age and the menstrual cycle phase. We performed MRI of the pelvis in 100 healthy women. For the uterus, they were further divided into two groups: one with myomas and/or adenomyosis and one without either. The volume of the uterus and cervix and thickness of the uterine wall layers were analysed by age and the menstrual cycle phase. The mean volume of the uterus in both groups and the cervix significantly increased with age to reach its peak at 41-50 years, and then dropped. Likewise, the thickness of the endometrium and the junctional zone, but not the myometrium, significantly increased until 41-50 years, and then decreased. When we compared the volume of the uterus and cervix and the thickness of the uterine wall layers between the two phases of the menstrual cycle, we found no significant differences. The volume of the uterus and cervix and the thickness of the endometrium and junctional zone differ significantly with age, but not between the two phases of the menstrual cycle. Knowledge of MRI-related normal values can be expected to aid the early identification of uterine pathologies. (orig.)

    The methods of the uterus cervix cancer proton-and-gamma treatment for the first time were elaborated in the CRC RAMS and ITEP in Moscow and then developed for the JINR proton beam in Dubna. The results of the clinical probation of the methods for the uterus cervix cancer treatment have confirmed the advantage of the proton irradiation. The most important advantage of the proton beam treatment is absence of postradiation reactions and complications in the critical organs (bladder and rectum). Up to now 31 patients with the uterus cervix cancer have been treated at the JINR phasotron. 6 of them had proton-and-gamma treatment combined with surgical operation and 22 patients received a radical proton-and-gamma treatment (without surgery). The clinical results are in good agreement with the preceding results of the ITEP group. After receiving proton-and-gamma radiotherapy of the uterus cervix, 83% of the patients are alive without recurrences, metastases and complications. 10 refs., 4 figs., 2 tabs

    This report describes a girl with congenital pouch colon (CPC), uterus didelphys with septate vagina, and a cloacal anomaly. The girl underwent cloacal reconstruction at the age of 15 months. Subsequently, at puberty, the child had primary amenorrhea with severe cyclic abdominal pain due to endometriosis of both the uteruses and adnexal cysts with hematometra and hematosalpinx. Laparotomy with removal of both uteri and the left fallopian tube was performed. Both uteri had atresia of the cervix uteri. This report emphasizes the need for comprehensive evaluation and a long-term management strategy for associated gynecologic anomalies in girls with CPC, especially with regard to patency of the outflow tract.

    While the function of progesterone receptor (PR) has been studied in the mouse vagina and uterus, its regulation and function in the cervix has not been described. We selectively deleted epithelial PR in the female reproductive tracts using the Cre/LoxP recombination system. We found that epithelial PR was required for induction of apoptosis and suppression of cell proliferation by progesterone (P4) in the cervical and vaginal epithelium. We also found that epithelial PR was dispensable for P4 to suppress apoptosis and proliferation in the uterine epithelium. PR is encoded by the Pgr gene, which is regulated by estrogen receptor α (ERα) in the female reproductive tracts. Using knock-in mouse models expressing ERα mutants, we determined that the DNA-binding domain (DBD) and AF2 domain of ERα were required for upregulation of Pgr in the cervix and vagina as well as the uterine stroma. The ERα AF1 domain was required for upregulation of Pgr in the vaginal stroma and epithelium and cervical epithelium, but not in the uterine and cervical stroma. ERα DBD, AF1, and AF2 were required for suppression of Pgr in the uterine epithelium, which was mediated by stromal ERα. Epithelial ERα was responsible for upregulation of epithelial Pgr in the cervix and vagina. Our results indicate that regulation and functions of epithelial PR are different in the cervix, vagina, and uterus.

    Key points Older pregnant women have a greater risk of operative delivery, still birth and post‐term induction.This suggests that maternal age can influence the timing of birth and processes of parturition.We have found that increasing maternal age in C57BL/6J mice is associated with prolongation of gestation and length of labour.Older pregnant mice also had delayed progesterone withdrawal and impaired myometrial function.Uterine ageing and labour dysfunction should be investigated further in older primigravid women. Abstract Advanced maternal age (≥35 years) is associated with increased rates of operative delivery, stillbirth and post‐term labour induction. The physiological causes remain uncertain, although impaired myometrial function has been implicated. To investigate the hypothesis that maternal age directly influences successful parturition, we assessed the timing of birth and fetal outcome in pregnant C57BL/6J mice at 3 months (young) and 5 months (intermediate) vs. 8 months (older) of age using infrared video recording. Serum progesterone profiles, myometrium and cervix function, and mitochondrial electron transport chain complex enzymatic activities were also examined. Older pregnant mice had a longer mean gestation and labour duration (P mice. Older mice did not exhibit the same decline in serum progesterone concentrations as younger mice. Cervical tissues from older mice were more distensible than younger mice (P mice (P mice, although there were no age‐induced changes to the enzymatic activities of the mitochondrial electron transport chain complexes. In conclusion, 8‐month‐old mice provide a useful model of reproductive ageing. The present study has identified potential causes of labour dysfunction amenable to investigation in older primigravid women. PMID:28083928

    A relation between apparent diffusion coefficient (ADC) values and tumor cellular density has been reported. The purpose of this study was to measure the ADC values of cervical cancers in the uterus and compare them with those of normal cervical tissues, and to test whether ADC could differentiate between normal and malignant cervical tissues in the uterus. Twelve consecutive female patients with cervical cancer of the uterus and ten female patients with other pelvic abnormalities were included in this study. ADC was measured at 1.5 T with b-factors of 0, 300 and 600 s/mm 2 using single-shot echo-planar diffusion-weighted imaging and a parallel imaging technique. The mean ADC value of cervical cancer lesions was 1.09±0.20 x 10 -3 mm 2 /s, and that of normal cervix tissue was 1.79±0.24 x 10 -3 mm 2 /s (P<0.0001). In nine patients treated by chemotherapy and/or radiation therapy, the mean ADC value of the cervical cancer lesion increased significantly after therapy (P<0.001). The present study showed, with a small number of patients, that ADC measurement has a potential ability to differentiate between normal and cancerous tissue in the uterine cervix. Further study is necessary to determine the accuracy of ADC measurement in monitoring the treatment response. (orig.)

    Purpose: To compare measurements of the uterus and cervix obtained with magnetic resonance imaging (MRI) and transabdominal ultrasound to determine whether ultrasound can identify the brachytherapy target and be used to guide conformal brachytherapy planning and treatment for cervix cancer. Methods and Materials: Consecutive patients undergoing curative treatment with radiation therapy between January 2007 and March 2012 were included in the study. Intrauterine applicators were inserted into the uterine canal while patients were anesthetized. Images were obtained by MRI and transabdominal ultrasound in the longitudinal axis of the uterus with the applicator in treatment position. Measurements were taken at the anterior and posterior surface of the uterus at 2.0-cm intervals along the applicator, from the external os to the tip of the applicator. Data were analyzed using Bland Altman plots examining bias and 95% limits of agreement. Results: A total of 192 patients contributed 1668 measurements of the cervix and uterus. Mean (±SD) differences of measurements between imaging modalities at the anterior and posterior uterine surface ranged from 1.5 (±3.353) mm to 3.7 (±3.856) mm, and −1.46 (±3.308) mm to 0.47 (±3.502) mm, respectively. The mean differences were less than 3 mm in the cervix. The mean differences were less than 1.5 mm at all measurement points on the posterior surface. Conclusion: Differences in the measurements of the cervix and uterus obtained by MRI and ultrasound were within clinically acceptable limits. Transabdominal ultrasound can be substituted for MRI in defining the target volume for conformal brachytherapy treatment of cervix cancer

    Maldevelopment of the Müllerian duct system may result in various urogenital anomalies including didelphic uterus with a hypoplastic cervix and obstructed hemi-vagina. We report a patient with this anomaly who was treated by laparoscopic hemi-hysterectomy and hysteroscopic resection of hemi-vagina. A 16-year-old patient who had complained of vaginal pus-like discharge on and off for 1 year was diagnosed by MRI to have a double uterus with obstructed right hemi-vagina and ipsilateral renal agenesis. After hysteroscopic identification of hypoplasia of the right uterine cervix, laparoscopic resection of the right uterus and right fallopian tube and hysteroscopic assisted resection of the vaginal septa were performed successfully. We think that combined laparoscopy and hysteroscopy may be an effective alternative in the management and diagnosis of Mullerian anomalies.

    A controversy exists as to whether functional smooth muscle exists in the cervix before and during pregnancy, potentially continuous with the uterus. We hypothesized that cervical smooth muscle persists through pregnancy and is functional. Uteri and cervices were taken from female virgin, 11 day, and 20 day (near labor) pregnant rats. All experiments used the uterus as a positive control. Three different smooth muscle proteins (smooth muscle α-actin, SM-22α, and calponin-1) allowed immunohistochemical detection of the continuous nature of the smooth muscle from the vagina, cervix, and uterus. Tissues were also hung in isolated tissue baths for the measurement of isometric smooth muscle contraction. Uterine and cervical homogenates were also used in Western analyses to measure protein expression. Immunohistochemistry revealed there to be smooth muscle as validated by an expression of all 3 markers in the cervix. This smooth muscle was continuous with that of the vagina and uterus. Smooth muscle α-actin was detected in virgin tissue (291.3 ± 32.2 arbitrary densitometry units/β-actin), day 11 (416.8 ± 19.5), and day 20 pregnant tissue (293.0 ± 34.4). The virgin, day 11, and day 20 cervices contracted 2.18 ± 0.24 g, 1.46 ± 0.08 g, and 3.88 ± 0.49 g (respectively) to depolarizing KCl. Cervices contracted at day 20 to the cholinergic muscarinic agonist carbamylcholine (maximum, 133% ± 18.2% KCl contraction, n = 4). These findings strongly support that smooth muscle is present in the cervix through pregnancy and continuous with the uterus. Copyright © 2015 Elsevier Inc. All rights reserved.

    Background and Purpose: To design and evaluate a 3D patient-specific model to predict the cervix-uterus shape and position. Methods and Materials: For 13 patients lying in prone position, 10 variable bladder filling CT-scans were acquired, 5 at planning and 5 after 40 Gy. The delineated cervix-uterus volumes in 2-5 pre-treatment CT-scans were used to generate patient-specific models that predict the cervix-uterus geometry by bladder volume. Model predictions were compared to delineations, excluding those used for model construction. The prediction error was quantified by the margin required around the predicted volumes to accommodate 95% of the delineated volume and by the predicted-to-delineated surface distance. Results: The prediction margin was significantly smaller (average 50%) than the margin encompassing the cervix-uterus motion. The prediction margin could be decreased (from 7 to 5 mm at planning and from 10 to 8 mm after 40 Gy) by increasing (from 2 to 5) the number of CT-scans used for the model construction. Conclusion: For most patients, even with a model based on only two CT-scans, the prediction error was well below the margin encompassing the cervix-uterus motion. The described approach could be used to create prior to treatment, an individualized treatment strategy.

    Full Text Available Uterine anomalies involving a double uterus, double cervix, also known as didelphys uterus, and complete septate vagina are rarely seen and have an associated fertility problem. However, artificial reproductive technology with embryo transfers can help solve this fertility challenge. Conception in the uterus in just one side is commonly seen for embryos, which are always transferred through the usually used (dilated vagina. We here present a patient with the above uterine anomaly who conceived with the aid of in vitro fertilization and embryo transfer to both uterine cavities under general anesthesia, which resulted in successful double singleton pregnancies with one fetus in each uterus. With intensive prenatal care, the pregnancy course for each fetus was rather uneventful. Although both fetuses were in cephalic presentation, cesarean section was performed at the 39th week of gestation with good outcomes in order to preclude anticipated difficulties if the baby had been delivered through the rarely dilated vagina. However, order of birth between the two fetuses was a crucial decision during the operation.

    Advantages of new flexible intracervical applicators treating cervical cancer with high dose rate afterloading brachytherapy are reported: The insertion of the flexible applicator is usually possible without anesthesia and dilatation of the cervix. Therefore the treatment can be performed on an outpatient basis. The risks of perforation and infection are minimal. Dosimetry and documentation of the applicator geometry are possible, if the planning system allows the definition of individual curves of an individual applicator. We now prefer flexible applicators instead of rigid steel applicators treating cervix carcinoma. (orig.) [de

  17. Effect of a copper intrauterine contraceptive device of estrogen and progesterone uptake by the Rabbit uterus and cervix

    1976-01-01

    The uptake of labelled estrogen 17β-6,7- 3 H and progesterone 1,2- 3 H by the uterus and cervix of rabbit fitted with inert (nylon) and active (copper wire) IUCD was studied by the in vitro method. The estrogen uptake was significantly high in IUCD fitted horn as compared to its contralateral control with both types of devices. The contralateral control-horn of copper treated animals showed significantly high estrogen uptake than that of intact control horn. This may be due to the bilateral effect of active (copper) IUCD. Similar offsets were not observed with nylon device. Estrogen uptake in the cervix was higher due to either of the devices used compared to that of intact control. The progesterone uptake was not modified in the IUCD horn by copper wire but there was an increase when a nylon suture was used. It appears that the mechanism of action of 'active' IUCDs may be different from that of 'inert' devices. (author)

    To validate interoperator reliability of brachytherapy radiation therapists (RTs) in obtaining an ultrasound image and measuring the cervix and uterine dimensions using transabdominal ultrasound. Patients who underwent MRI with applicators in situ after the first insertion were included in the study. Imaging was performed by three RTs (RT1, RT2, and RT3) with varying degrees of ultrasound experience. All RTs were required to obtain a longitudinal planning image depicting the applicator in the uterine canal and measure the cervix and uterus. The MRI scan, taken 1 hour after the ultrasound, was used as the reference standard against which all measurements were compared. Measurements were analyzed with intraclass correlation coefficient and Bland-Altman plots. All RTs were able to obtain a suitable longitudinal image for each patient in the study. Mean differences (SD) between MRI and ultrasound measurements obtained by RTs ranged from 3.5 (3.6) to 4.4 (4.23) mm and 0 (3.0) to 0.9 (2.5) mm on the anterior and posterior surface of the cervix, respectively. Intraclass correlation coefficient for absolute agreement between MRI and RTs was >0.9 for all posterior measurement points in the cervix and ranged from 0.41 to 0.92 on the anterior surface. Measurements were not statistically different between RTs at any measurement point. RTs with variable training attained high levels of interoperator reliability when using transabdominal ultrasound to obtain images and measurements of the uterus and cervix with brachytherapy applicators in situ. Access to training and use of a well-defined protocol assist in achieving these high levels of reliability. Copyright © 2016 American Brachytherapy Society. Published by Elsevier Inc.

    We undertook the present study to investigate the echographic characteristics of the uterus and cervix of female bonnet monkeys (Macaca radiata) during the proliferative and secretory phases of the menstrual cycle. The cervix was tortuous in shape and measured 2.74 ± 0.30 cm (mean ± SD) in width by 3.10 ± 0.32 cm in length. The cervical lumen contained 2 or 3 colliculi, which projected from the cervical canal. The echogenicity of cervix varied during proliferative and secretory phases. The uterus was pyriform in shape (2.46 ± 0.28 cm × 1.45 ± 0.19 cm) and consisted of serosa, myometrium, and endometrium. The endometrium generated a triple-line pattern; the outer and central lines were hyperechogenic, whereas the inner line was hypoechogenic. The endometrium was significantly thicker during the secretory phase (0.69 ± 0.12 cm) than during the proliferative phase (0.43 ± 0.15 cm). Knowledge of the echogenic changes in the female reproductive organs of bonnet monkeys during a regular menstrual cycle may facilitate understanding of other physiologic and pathophysiologic changes.

    For online adaptive radiotherapy of cervical cancer, fast and accurate image segmentation is required to facilitate daily treatment adaptation. Our aim was twofold: (1) to test and compare three intra-patient automated segmentation methods for the cervix-uterus structure in CT-images and (2) to improve the segmentation accuracy by including prior knowledge on the daily bladder volume or on the daily coordinates of implanted fiducial markers. The tested methods were: shape deformation (SD) and atlas-based segmentation (ABAS) using two non-rigid registration methods: demons and a hierarchical algorithm. Tests on 102 CT-scans of 13 patients demonstrated that the segmentation accuracy significantly increased by including the bladder volume predicted with a simple 1D model based on a manually defined bladder top. Moreover, manually identified implanted fiducial markers significantly improved the accuracy of the SD method. For patients with large cervix-uterus volume regression, the use of CT-data acquired toward the end of the treatment was required to improve segmentation accuracy. Including prior knowledge, the segmentation results of SD (Dice similarity coefficient 85 ± 6%, error margin 2.2 ± 2.3 mm, average time around 1 min) and of ABAS using hierarchical non-rigid registration (Dice 82 ± 10%, error margin 3.1 ± 2.3 mm, average time around 30 s) support their use for image guided online adaptive radiotherapy of cervical cancer.

    This study aimed to analyze the effects of nandrolone decanoate on the ovaries and uterus of adult females rats. This drug was administered intraperitoneally, at one, two and three doses of 3 mg nandrolone decanoate/kg of body weight, respectively, in the first, second and third week of treatment. The females of the control group received a physiological solution. The rats treated with nandrolone decanoate showed estral acyclicity and there was destruction of follicular units and an absence of corpus luteum in the ovaries. In the uterus, the drug promoted morphological alterations, characterized by vacuolated epithelium and endometrial stroma fibrosis. Ovary, uterus and pituitary weights were not affected by the steroid treatment. Nandrolone decanoate affects the sexual cycle and promotes histological alterations in the ovaries and uterus of adult female rats.

    The role of interleukin-1 (IL-1), a pro-inflammatory cytokine, in parturition is typically noted by changes in its concentrations. Studying the expression of its receptor family, IL-1 receptor (IL-1R) 1, IL-1R2, IL-1R accessory protein (IL-1RAcP), and its predominantly brain isoform, IL-1RAcPb, during late gestation in the uterus in the Long-Evans rat is another. We assessed changes in their mRNA and protein relative abundance in the uterus and compared IL-1RAcP and IL-1RAcPb mRNA abundance in uterus, cervix, ovaries, placenta, and whole blood of Long-Evans rats during late gestation or in RU486 and progesterone-treated dams using quantitative real-time PCR and western immunoblotting. IL-1R1, IL-1RAcP, and IL-1RAcPb mRNA abundance significantly increased in the uterus at delivery whereas IL-1R2 mRNA abundance significantly decreased. IL-1R1 protein increased at term and IL-1R2 protein decreased at term compared to nonpregnant uteri. IL1-RAcPb mRNA abundance was less than IL-1RAcP, but in the lower uterine segment it was the highest of all tissues examined. RU486 stimulated preterm delivery and an increase in IL-1R1 mRNA abundance whereas progesterone administration extended pregnancy and suppressed the increase in IL-1R1. These data suggest that changes in uterine sensitivity to IL-1 occur during late gestation and suggest another level of regulation for the control of delivery. The roles for IL-1RAcP and IL-1RAcPb need to be determined, but may relate to different intracellular signaling pathways. © 2016 The Authors.

    Estrogen-mediated uterus endometrium instability is considered as one of the etiological factors in dysfunctional uterine bleeding (DUB) and uterine cancer. Saraca asoca (Family: Fabaceae) and its fermented preparation, Asokarishta, are extensively used as uterine tonic to treat gynecological disorders in Ayurveda. The present study evaluated the effect of S. asoca (Asoka) on estrogen-induced endometrial thickening of rat uterus. Endometrial thickening was induced by intraperitoneal injection of estradiol (20 μg/kg b.wt) to 8-day-old immature rats for alternate 5 days. Methanolic extract (200 mg/kg b. wt) from S. asoca bark was given orally along with estradiol. Uterus endometrial thickening was analyzed histopathologically and serum estrogen level by radioimmunoassay (RIA). Cyclooxygenase (COX-2) expression in rat uterus was also estimated by Western blot. Anti-inflammatory activity of the extract was analyzed by formalin- and carrageenan-elicited paw edema models in mouse. Uterus endometrium proliferation and keratinized metaplasia with seven to eight stratified epithelial layers on day 16 was observed in rats administered with estradiol. Treatment with S. asoca reduced the thickening to two to four layers and the serum estrogen level diminished significantly to 82.9±12.87 pg/mL compared to rats administered with estrogen alone (111.2±10.68 pg/mL). A reduction of formalin- and carrageenan-induced paw edema in mouse by S. asoca extract was observed. Lower level of lipopolysaccharides (LPS)-induced COX-2 enzyme in rat uterus by the extract further confirms its anti-inflammatory activity. Present study reveals the antiproliferative and antikeratinizing effects of S. asoca in uterus endometrium possibly through its anti-estrogenic and anti-inflammatory properties.

    The durational effects of chronic stress on the Fallopian tubes and uterus were studied by exposing rats to stressors in the form of restraint (1h) and forced swimming (15min) daily for 4, 8 or 12 weeks. One group of stressed rats from each time period was then maintained without exposure to stressors for a further 4 weeks to assess their ability to recover from stress. All time periods of stress exposure resulted in decreased weight of the body and Fallopian tubes; however, the relative weight of the uterus and serum concentrations of oestradiol and insulin increased significantly. The antioxidant potential was decreased with increased malondialdehyde concentrations in the Fallopian tubes following all durations of exposure and after 4 and 8 weeks of stress exposure in the uterus. Interestingly, rats stressed for 12 weeks showed an increase in serum testosterone concentration and antioxidant enzyme activities with a decrease in malondialdehyde concentration in the uterus. The antioxidant enzyme activities and malondialdehyde concentration in the Fallopian tubes of all recovery group rats were similar to stressed rats. However, in the uterus these parameters were similar to controls in recovery group rats after 4 weeks or 8 weeks of exposure, but after 12 weeks of stress exposure these parameters did not return to control levels following the recovery period. These results reveal, for the first time, that chronic stress elicits an irreversible decrease in antioxidant defence in the Fallopian tubes irrespective of exposure duration, whereas the uterus develops reversible oxidative stress under short-term exposure but increased antioxidant potential with endometrial proliferation following long-term exposure.

    Full Text Available The pollution of endocrine disruptors and its impact on human reproductive system have attracted much attention. Di-(2-ethylhexyl phthalate (DEHP, an environmental endocrine disruptor, is widely used in food packages, containers, medical supplies and children’s toys. It can cause diseases such as infertility, sexual precocity and uterine bleeding and thus arouse concerns from the society and scholars. The effect of DEHP on pubertal female reproductive system is still not well-studied. This study was to investigate the effects of DEHP on the hypothalamus–uterus in pubertal female rats, reveal the reproductive toxicity of DEHP on pubertal female rats and its mechanism, and provide scientific evidence for the evaluation of toxicity and toxic mechanism of DEHP on reproductive system. Forty-eight pubertal female rats were randomly divided into four groups and respectively administered via oral gavage 0, 250, 500, or 1000 mg/kg/d DEHP in 0.1 mL corn oil/20 g body weight for up to four weeks. Compared with control rats, the DEHP-treated rats showed: (1 higher gonadotropin-releasing hormone (GnRH level in the hypothalamus; (2 higher protein levels of GnRH in the hypothalamus; and (3 higher mRNA and protein levels of GnRH receptor (GnRHR in the uterus. Our data reveal that DEHP exposure may lead to a disruption in pubertal female rats and an imbalance of hypothalamus–uterus. Meanwhile, DEHP may, through the GnRH in the hypothalamus and its receptor on the uterus, lead to diseases of the uterus. DEHP may impose a negative influence on the development and functioning of the reproductive system in pubertal female rats.

    The aim of this study was to investigate the immunolocalization and the existence of thyroid hormone receptors (THR) (alpha1/alpha2) in rat uterus and oviduct. For this purpose 6 female Wistar albino rats found in estrous period were used. Tissue samples fixed in 10% neutral formalin were examined immunohistochemically. Sections were incubated with primary mouse-monoclonal THR (alpha1/alpha2) antibody. In uterus, THR (alpha1/alpha2) immunoreacted strongly with uterine luminal epithelium, endometrial gland epithelium and endometrial stromal cells and, moderately with myometrial smooth muscle. In oviduct, they were observed moderately in the epithelium of the tube and the smooth muscle cells of the muscular layer. In conclusion, the presence of THR in uterus and oviduct suggests that these organs are an active site of thyroid hormones

    Melatonin has been described as a protective agent against cell death and oxidative stress in different tissues, including in the reproductive system. However, the information on the action of this hormone in rat uterine apoptosis is low. Our objective was to evaluate the effects of melatonin on mechanisms of cell death in uterus of rats exposed to continuous light stress. Twenty adult Wistar rats were divided into two groups: GContr (vehicle control) and GExp which were treated with melatonin (0.4 mg/mL), both were exposed to continuous light for 90 days. The uterus was removed and processed for quantitative real time PCR (qRT-PCR), using PCR-array plates of the apoptosis pathway; for immunohistochemistry and TUNEL. The results of qRT-PCR of GEXP group showed up-regulation of 13 and 7, pro-apoptotic and anti-apoptotic genes, respectively, compared to GContr group. No difference in pro-apoptotic proteins (Bax, Fas and Faslg) expression was observed by immunohistochemistry, although the number of TUNEL-positive cells was lower in the group treated with melatonin compared to the group not treated with this hormone. Our data suggest that melatonin influences the mechanism and decreases the apoptosis in uterus of rats exposed to continuous light.

    Metabolites of [ 3 H]progesterone were quantitated from incubations of hypothalamus, pituitary, and uterus of rats during different stages of pregnancy. The hypothalamus, anterior pituitary, and a section of uterus from five rats on Days 1, 8, 15, and 21 of pregnancy were incubated individually with [3H]progesterone and analyzed for metabolite formation by reverse isotopic dilution analysis. The radioactive metabolites present were 5 alpha-pregnane-3,20-dione (5 alpha-DHP), 3 alpha-hydroxy-5 alpha-pregnan-20-one, 20 alpha-hydroxy-4-pregnen-3-one, 20 alpha-hydroxy-5 alpha-pregnan-3-one, and 5 alpha-pregnane-3 alpha, 20 alpha-diol. The major metabolite formed by the hypothalamus and pituitary was 5 alpha-DHP. In the pituitary samples, formation of 5 alpha-DHP was decreased on Days 15 and 21 of pregnancy compared to Day 1, and formation of 20 alpha-hydroxy-5 alpha-pregnan-3-one was decreased on Day 21 compared to Day 1. In the uterine samples, 3 alpha-hydroxy-5 alpha-pregnan-20-one was the major metabolite formed at all stages of pregnancy. The formation of all metabolic products of progesterone by the uterus was increased on Day 21 compared to Days 1, 8, and 15 of pregnancy. No changes in the formation of progesterone metabolites were observed in the hypothalamic samples during pregnancy. It is concluded that there are different profiles in the in vitro metabolism of [3H]progesterone by the hypothalamus, pituitary, and uterus of the rat during the course of pregnancy

    As the critical gatekeeper for birth, prepartum remodeling of the cervix is associated with increased resident macrophages (Mφ), proinflammatory processes, and extracellular matrix degradation. This study tested the hypothesis that expression of genes unique to Mφs characterizes the prepartum from unremodeled nonpregnant cervix. Perfused cervix from prepartum day 21 postbreeding (D21) or nonpregnant (NP) rats, with or without Mφs, had RNA extracted and whole genome microarray analysis performed. By subtractive analyses, expression of 194 and 120 genes related to Mφs in the cervix from D21 rats were increased and decreased, respectively. In both D21 and NP groups, 158 and 57 Mφ genes were also more or less up- or down-regulated, respectively. Mφ gene expression patterns were most strongly correlated within groups and in 5 major clustering patterns. In the cervix from D21 rats, functional categories and canonical pathways of increased expression by Mφ gene related to extracellular matrix, cell proliferation, differentiation, as well as cell signaling. Pathways were characteristic of inflammation and wound healing, e.g., CD163, CD206, and CCR2. Signatures of only inflammation pathways, e.g., CSF1R, EMR1, and MMP12 were common to both D21 and NP groups. Thus, a novel and complex balance of Mφ genes and clusters differentiated the degraded extracellular matrix and cellular genomic activities in the cervix before birth from the unremodeled state. Predicted Mφ activities, pathways, and networks raise the possibility that expression patterns of specific genes characterize and promote prepartum remodeling of the cervix for parturition at term and with preterm labor.

    Binding of ovine LH to uterine tissue preparation from intact and ovariectomised rat clearly indicates that uterus possesses specific binding sites for LH. Binding characteristics of LH to uterine tissue preparation from intact rat showed saturability with high affinity and low capacity. Scatchard plot analysis showed dissociation constant of the specific binding site to be 0.12 x 10 -9 mol/l and the number of binding sites was 2.31±0.05 fmol/mg protein. Ovariectomy did not change the binding affinity but effected a decrease in the number of binding sites (1.7 ± 0.08 f mol/mg protein). LH treatment of ovariectomized (ovx) rat had no effect on binding affinity but significantly increased the number of binding sites (3.23 ± 0.1 f mol/mg protein). Reduction of uterine weight due to ovariectomy and marked increase of ovx rat uterine weight by LH administration indicate a source of estrogen in ovx rat. An in vitro uterine tissue slice (from intact and ovx rat) incubation showed depletion of 17 β-estradiol (E 2 ) content in ovx rat which significantly elevated on LH addition. Data suggest the LH binding to rat uterine tissue has biological relevance. (author). 16 refs., 4 figs. 1 tab

    Full Text Available Abstract Background Heat shock proteins (Hsps are a set of highly conserved proteins, Hsp105, has been suggested to play a role in reproduction. Methods Spatio-temporal expression of Hsp105 in rat uterus during peri-implantation period was examined by immunohistochemistry and Western blot, pseudopregnant uterus was used as control. Injection of antisense oligodeoxynucleotides to Hsp105 into pregnant rat uteri was carried out to look at effect of Hsp105 on embryo implantation. Results Expression of Hsp105 was mainly in the luminal epithelium on day 1 of pregnancy, and reached a peak level on day 5, whereas in stroma cells, adjacent to the implanting embryo, the strongest expression of Hsp105 was observed on day 6. The immunostaining profile in the uterus was consistent with that obtained by Western blot in the early pregnancy. In contrast, no obvious peak level of Hsp105 was observed in the uterus of pseudopregnant rat on day 5 or day 6. Furthermore, injection of antisense oligodeoxynucleotides to Hsp105 into the rat uterine horn on day 3 of pregnancy obviously suppressed the protein expression as expected and reduced number of the implanted embryos as compared with the control. Conclusion Temporal and spatial changes in Hsp105 expression in pregnant rat uterus may play a physiological role in regulating embryo implantation.

    Peripheral insulin resistance and hyperandrogenism are the primary features of polycystic ovary syndrome (PCOS). However, how insulin resistance and hyperandrogenism affect uterine function and contribute to the pathogenesis of PCOS are open questions. We treated rats with insulin alone or in combination with human chorionic gonadotropin (hCG) and showed that peripheral insulin resistance and hyperandrogenism alter uterine morphology, cell phenotype, and cell function, especially in glandular epithelial cells. These defects are associated with an aberration in the PI3K/Akt signaling pathway that is used as an indicator for the onset of insulin resistance in classical metabolic tissues. Concomitantly, increased GSK3β (Ser-9) phosphorylation and decreased ERK1/2 phosphorylation in rats treated with insulin and hCG were also observed. We also profiled the expression of glucose transporter (Glut) isoform genes in the uterus under conditions of insulin resistance and/or hyperandrogenism. Finally, we determined the expression pattern of glycolytic enzymes and intermediates during insulin resistance and hyperandrogenism in the uterus. These findings suggest that the PI3K/Akt and MAPK/ERK signaling pathways play a role in the onset of uterine insulin resistance, and they also suggest that changes in specific Glut isoform expression and alterations to glycolytic metabolism contribute to the endometrial dysfunction observed in PCOS patients.

    Ovarian steroid hormones, progesterone (P4), and estradiol (E2) strictly regulate the endometrial tissue remodeling required for successful embryo implantation. Indian hedgehog (Ihh) is up-regulated by P4 and critically mediates uterine receptivity in the mouse. However, the regulation of Ihh expression during the implantation period still remains unclear. The present study was conducted to elucidate the mechanism of the steroidal regulation in the expression of Ihh and Gli1, the mediator of the Ihh pathway. Ihh mRNA was expressed in the rat uterus on 3.5-5.5 days post-coitus (dpc), while Gli1 expression transiently increased at 3.5 dpc but decreased significantly on 5.5 dpc (P Ihh was induced by the implantation-induced E2 treatment in the primed rat uterus. In contrast, expression of Gli1 was significantly decreased by E2 treatment (P = 0.016). In the case of ICI182.780 (ICI) treatment, Ihh expression was eliminated by ICI, whilst Gli1 expression increased. These results suggest that Ihh expression is maintained at a high level until the initiation of implantation, while the expression of Gli1 is decreased just prior to the initiation of implantation depending on the E2 action. This observation aids in the understanding of the Ihh signaling pathway mediating uterine remodeling for implantation.

    The reproductive transition of women through peri- to postmenopause is characterized by changes in steroid hormone levels due to the cessation of the ovarian function. Beside several complaints associated with these hormonal changes, the deterioration of the trabecular bone micro-architecture and the loss of skeletal mass can cause osteoporosis. At this life stage, women often have a reproductive history of one to several pregnancies. The ovariectomized skeletally mature rat (>10 months old) is one of the most commonly used animal models for postmenopausal osteoporosis research. Despite the fact that mammals can undergo up to several reproductive cycles (primi-/pluriparous), nulliparous animals are often used and the question whether changes in the hormonal milieu subsequently affect the skeleton and influence the outcome of intervention studies is often neglected in study designs. Therefore, the aim of the present study was to compare the estrogen responsiveness of nulliparous and pluriparous rats. For this purpose, one year old virgin or retired breeder Lewis rats were either sham operated or ovariectomized, whereas half of the ovariectomized animals received subcutaneous 17β-estradiol pellets eight weeks after surgery. After another four weeks, the effects on the uterus were determined by expression analysis of estrogen-dependently regulated steroid receptor genes and well-established marker genes. Moreover, trabecular bone parameters in the tibia were analyzed by micro-computed tomography (μCT). Parity-dependency in estrogen responsiveness was observed with respect to the achieved serum E2 levels in response to similar E2 treatment. This led to differences both on the uterus wet weight and on the expression level of uterine target genes. In addition, a reversal of the ovariectomy-induced changes of the bone architecture after 17β-estradiol substitution was only observed among the nulliparous. In conclusion, the observations of this study support parity

    OBJECTIVE: To analyze the amount of glycosaminoglycans in the uterine cervix during each phase of the rat estrous cycle. DESIGN: Based on vaginal smears, forty female, regularly cycling rats were divided into four groups (n = 10 for each group): GI – proestrous, GII – estrous, GIII – metaestrous and GIV – diestrous. Animals were sacrificed at each phase of the cycle, and the cervix was immediately removed and submitted to biochemical extraction and determination of sulfated glycosaminoglycans and hyaluronic acid. The results were analyzed by ANOVA followed by the Bonferroni post-hoc test. RESULTS: The uterine cervix had the highest amount of total sulfated glycosaminoglycans and dermatan sulfate during the estrous phase (8.90 ± 0.55 mg/g of cetonic extract, phyaluronic acid in the uterine cervix during the estrous cycle. CONCLUSION: Our data suggest that the amount of total sulfated glycosaminoglycans may be influenced by hormonal fluctuations related to the estrous cycle, with dermatan sulfate and heparan sulfate being the glycosaminoglycans most sensitive to hormonal change.

    Polycystic ovary syndrome (PCOS) causes female subfertility with ovarian disorders and may be associated with increased rate of early-pregnancy failure. Rat PCOS models were established using letrozole to understand the uterine pathogenesis of PCOS. The differential expression of microRNAs (miRNAs) was observed in rat uterus with PCOS. After estrous cycles were disrupted, significantly abnormal ovarian morphology and hormone level were observed in rats with PCOS. A total of 148 miRNAs differentially expressed were identified in the uterus from the letrozole-induced rat model compared with the control. These miRNAs included 111 upregulated miRNAs and 37 downregulated miRNAs. The differential expression of miR-484, miR-375-3p, miR-324-5p, and miR-223-3p was further confirmed by quantitative reverse transcription polymerase chain reaction. Bioinformatic analysis showed that these four miRNAs were predicted to regulate a large number of genes with different functions. Pathway analysis supported that target genes of miRNAs were involved in insulin secretion and signaling pathways, such as wnt, AMPK, PI3K-Akt, and Ras. These data indicated that miRNAs differentially expressed in rat uterus with PCOS may be associated with PCOS pathogenesis in the uterus. Our findings can help clarify the mechanism of uterine defects in PCOS. Copyright © 2016. Published by Elsevier B.V.

  20. Antispasmodic effects of Pycnocycla spinosa seed and aerial part extracts on rat ileum and uterus smooth muscle contractions

    2008-08-01

    Full Text Available Background and the purpose of study: Hydroalcoholic extract of Pycnocycla spinosa has a relaxant effect on ileum and inhibits castor oil induced diarrhoea in mice. However, effects of P. spinosa seed extracts on ileum and uterus hasn't been investigated.  The aim of this study was to investigate effect of P. spinosa seed and extracts of the aerial part on rat ileum and uterus smooth muscle contraction. Methods: A 70% ethanol extract of seed and aerial parts of P. spinosa was prepared by a percolation method. Uterine horns or ileum were dissected from non-pregnant female Wistar rats (200-230g and cut into longitudinal strips and mounted for isotonic recording under 1g tension in Tyrode's solution. Effects of the extracts were examined on tonic contractions induced by KCl (80mM on both tissues and on phasic spasm induced by oxytocin (0.002iu/ml on the uterus. Results: The aerial part extract inhibited rat ileum contractions induced by 80mM KCl (IC50=42±3.4mg/ml in a concentration dependent manner and it also inhibited rat uterus contraction induced by 80 mM KCl. However, its inhibitory effects were observed with higher concentration of the extract (IC50=420±90mg/ml and at concentration of 1.28mg/ml of the extract in the bath the response was 19±7%.  The aerial part extract (40-640mg/ml also reduced the evoked phasic response of uterus by oxytocin (IC50=71±17.3mg/ml. The seed extract reduced the uterus response to oxytocin in a concentration-dependent manner, and inhibited tissue response completely at 160mg/ml (IC50=27±4mg/ml.  Major conclusion: From this study it was concluded that the seed extract of P. spinosa have similar inhibitory properties on rat isolated uterus and ileum contractions, while the extract of the aerial part of P. spinosa is more selective inhibitor of ileum contraction, and at higher concentrations it also inhibits uterus spasm.

    Purpose: To more accurately define clinical target volume for cervical cancer radiation treatment planning by evaluating tumor microscopic extension toward the uterus body (METU) in International Federation of Gynecology and Obstetrics stage Ib-IIa squamous cell carcinoma of the cervix (SCCC). Patients and Methods: In this multicenter study, surgical resection specimens from 318 cases of stage Ib-IIa SCCC that underwent radical hysterectomy were included. Patients who had undergone preoperative chemotherapy, radiation, or both were excluded from this study. Microscopic extension of primary tumor toward the uterus body was measured. The association between other pathologic factors and METU was analyzed. Results: Microscopic extension toward the uterus body was not common, with only 12.3% of patients (39 of 318) demonstrating METU. The mean (±SD) distance of METU was 0.32 ± 1.079 mm (range, 0-10 mm). Lymphovascular space invasion was associated with METU distance and occurrence rate. A margin of 5 mm added to gross tumor would adequately cover 99.4% and 99% of the METU in the whole group and in patients with lymphovascular space invasion, respectively. Conclusion: According to our analysis of 318 SCCC specimens for METU, using a 5-mm gross tumor volume to clinical target volume margin in the direction of the uterus should be adequate for International Federation of Gynecology and Obstetrics stage Ib-IIa SCCC. Considering the discrepancy between imaging and pathologic methods in determining gross tumor volume extent, we recommend a safer 10-mm margin in the uterine direction as the standard for clinical practice when using MRI for contouring tumor volume.

    We present the application of Fourier transform-second-harmonic generation (FT-SHG) imaging to evaluate the arrangement of collagen fibers in five nonpregnant rat cervices. Tissue slices from the mid-cervix and near the external orifice of the cervix were analyzed in both two-dimensions (2D) and three-dimensions (3D). We validate that the cervical microstructure can be quantitatively assessed in three dimensions using FT-SHG imaging and observe collagen fibers oriented both in and out-of-plane in the outermost and the innermost layers, which cannot be observed using 2D FT-SHG analysis alone. This approach has the potential to be a clinically applicable method for measuring progressive changes in collagen organization during cervical remodeling in humans. © 2013 The Authors Journal of Microscopy © 2013 Royal Microscopical Society.

    Full Text Available Exposure to estrogenic compounds during critical periods of fetal development could result in adverse effects on the development of reproductive organs that are not apparent until later in life. Bisphenol A (BPA, which is employed in the manufacture of a wide range of consumer products, is a prime candidate for endocrine disruption. We examined BPA to address the question of whether in utero exposure affects the uterus of the offspring and studied the expression and distribution of the estrogen receptors alpha (ERβ and beta (ERα, because estrogens influence the development, growth, and function of the uterus through both receptors. Gravid Sprague-Dawley dams were administered by gavage either 0.1 or 50 mg/kg per day BPA or 0.2 mg/kg per day 17α-ethinyl estradiol (EE2 as reference dose on gestation days 6 through 21. Female offspring were killed in estrus. Uterine morphologic changes as well as ERα and ERβ distribution and expression were measured by immunohistochemistry and Western blot analysis. Striking morphologic changes were observed in the uterine epithelium of postpubertal offspring during estrus of the in utero BPA-treated animals (the thickness of the total epithelium was significantly reduced. ERβ expression was increased in the 50-mg BPA and EE2-treated group. In contrast, we observed significantly decreased ERβ expression in all BPA- and EE2-treated animals when compared with the control. In summary, these results clearly indicate that in utero exposure of rats to BPA promotes uterine disruption in offspring. We hypothesize that the uterine disruption could possibly be provoked by a dysregulation of ERα and ERβ.

    16 alpha-[77Br]bromoestradiol-17 beta (Compound 1) has been synthesized by radiobromination of estrone enoldiacetate. Tissue uptake studies performed 1 h after administration of Compound 1 to immature or mature female rats showed uterus-to-blood ratios of 13, with nontarget issue-to-blood ratios ranging from 0.6 to 2. Co-administration of unlabelled estradiol caused a selective depression in the uterine uptake with no effect on nontarget tissue uptake. In adult animals bearing adenocarcinomas induced by DMBA (7,12-dimethylbenz(a)anthracene), tumor-to-blood ratios of 6.3 were obtained, this uptake also being depressed in animals treated with unlabeled estradiol. The studies demonstrate that Compound 1 has suitable binding properties and sufficiently high specific activity so that its uptake in estrogen target tissues in vivo is mediated primarily by the estrogen receptor. Furthermore, they suggest that this compound may be suitable for imaging human breast tumors that contain estrogen receptors

    Highlights: • Neonatal exposure to GBH lead to endometrial hyperplasia and increase proliferation. • GBH disrupts proteins involved in uterine organogenetic differentiation. • GBH exposure induced persistent increase of PR and Hoxa10 proteins. - Abstract: Glyphosate-based herbicides (GBHs) are extensively used to control weeds on both cropland and non-cropland areas. No reports are available regarding the effects of GBHs exposure on uterine development. We evaluated if neonatal exposure to a GBH affects uterine morphology, proliferation and expression of proteins that regulate uterine organogenetic differentiation in rats. Female Wistar pups received saline solution (control, C) or a commercial formulation of glyphosate (GBH, 2 mg/kg) by sc injection every 48 h from postnatal day (PND) 1 to PND7. Rats were sacrificed on PND8 (neonatal period) and PND21 (prepubertal period) to evaluate acute and short-term effects, respectively. The uterine morphology was evaluated in hematoxylin and eosin stained sections. The epithelial and stromal immunophenotypes were established by assessing the expression of luminal epithelial protein (cytokeratin 8; CK8), basal epithelial proteins (p63 and pan cytokeratin CK1, 5, 10 and 14); and vimentin by immunohistochemistry (IHC). To investigate changes on proteins that regulate uterine organogenetic differentiation we evaluated the expression of estrogen receptor alpha (ERα), progesterone receptor (PR), Hoxa10 and Wnt7a by IHC. The GBH-exposed uteri showed morphological changes, characterized by an increase in the incidence of luminal epithelial hyperplasia (LEH) and an increase in the stromal and myometrial thickness. The epithelial cells showed a positive immunostaining for CK8, while the stromal cells for vimentin. GBH treatment increased cell proliferation in the luminal and stromal compartment on PND8, without changes on PND21. GBH treatment also altered the expression of proteins involved in uterine organogenetic

    Two hundred and twelve Holstein and Jersey cows were in a study to determine factors that affected reproductive traits. First ovulation occurred about 3 wk postpartum, and interval to first ovulation was greater in cows that had clinical abnormalities postpartum than in normal cows. Jerseys producing more milk ovulated sooner postpartum than lower producing herdmates. Involution of cervix and uterus occurred later postpartum in cows that had clinical problems postpartum. Involution of genital tract occurred later postpartum in older cows and sooner postpartum in cows that had higher milk yields. Duration of first postpartum estrous cycle was 4 days less than for second postpartum cycle. Percentages of estrous cycles detected by standing estrus were 43 and 73% for Holsteins and Jerseys. Estrous detection rates were highest for cows that produced slightly above the mean milk yield and did not differ between cows in highest and lowest milk production quartiles. First detected estrus and days to first insemination occurred later postpartum in Holsteins as milk yield deviation from herdmates increased, regardless of sign. In Jerseys, days to first insemination and days open increased linearly as milk yield increased. Days to first insemination and conception were greater in cows with postpartum clinical problems. Conception rate at first insemination postpartum increased in proportion to concentration of progesterone in blood samples collected during 12 days before first insemination. Overall, clinical problems at parturition and postpartum lowered reproductive performance in both breeds. There was a slight antagonism between milk yield and reproductive performance (days open) in Jerseys but not in Holsteins.

    Restoring the pH of cervicovaginal fluid is important for the cervicovaginal health after menopause. Genistein, which is a widely consumed dietary health supplement to overcome the post-menopausal complications could help to restore the cervicovaginal fluid pH. We hypothesized that genistien effect involves changes in expression of NHE-1, 2 and 4 proteins and mRNAs in the cervix. This study investigated effect of genistein on NHE-1, 2 and 4 protein and mRNA expression in the cervix in order to elucidate the mechanisms underlying possible effect of this compound on cervicovaginal fluid pH after menopause. Ovariectomised adult female rats received 25, 50 and 100 mg/kg/day genistein for seven consecutive days. At the end of the treatment, animals were sacrificed and cervix was harvested. Expression of Nhe-1, 2 and 4 mRNA were analyzed by Real-time PCR while distribution of NHE-1, 2 and 4 protein were observed by immunohistochemistry. Treatment with 50 and 100 mg/kg/day genistein caused marked increase in the levels of expression and distribution of NHE-1, 2 and 4 proteins in the endocervical epithelia. Levels of Nhe-1, 2 and 4 mRNA in the cervix were also increased. Coadministration of ICI 182 780 and genistein reduced the expression levels of NHE-1, 2 and 4 proteins and mRNAs in the cervix. Enhanced expression of NHE-1, 2 and 4 proteins and mRNAs expression in cervix under genistein influence could help to restore the cervicovaginal fluid pH that might help to prevent cervicovaginal complications related to menopause.

    The cervix uteri is a rigid tube which connects the uterus with the vagina and during most of the time it is firmly closed. During oestrus, late pregnancy and parturition, the morphological appearance in the cervix changes markedly, resulting in a softer cervix, which during parturition can even be

    Full Text Available PURPOSE: To verify if uterine cerclage can induce craniosynostosis or any cranial deformity in new born Wistar rats. METHODS: One pregnant female Wistar rat underwent laparotomy on day 18 of gestation and the uterus cervix was closed with a 3-0 nylon suture to avoid delivery, that occurs normally on the 21 day. The suture was released after 48 hours beyond the normal gestation period. The female rat delivered 11 pups. Six surviving rats from the delivery (group A - constrained group. Two rats were born from another mother and in the same age were used as control group (group B - 2 nonconstrained controls were allowed to grow. They were sacrificed 1.2 years after their birth all the eight animals. Linear measurement, routine histology and computed tomography of the skull were performed at the time of their death to evaluate the cranial asymmetries by mesurements of the anatomical landmarks of the craniofacial skeleton of the rats on the two groups and compared then. RESULTS: We did not observe statistically significant differences in any of the compared measurements (p>0.05 obtained through the morphologic and radiologic methods. Histologic examinations did not reveal any sign of premature fusion or suture imbrications. Critical decrease in longitudinal body size was noticed as the limbs too in all the animals of group A. CONCLUSION: Constriction of uterine cervix leads to fetus suffering, even death for a few animals, associated to small body size, but not to craniosynostosis.OBJETIVO: Verificar se a cerclagem intra-uterina pode induzir, ao nascimento de ratos Wistar, craniossinostose ou qualquer outra deformidade craniana.

    the expression of SK3 in the uterus of rats stimulated with 17β-estradiol and progesterone in order to get an in depth understanding of the rat uterine SK3. Using immunohistochemistry SK3 was localized to the glandular and luminal endometrial lamina epitheliali. Furthermore, a weak signal was observed...... in the myometrium. Using Western blot the protein level of SK3 was found to increase in uteri from animals treated with 17β-estradiol, an effect that was not reflected at the mRNA level. The levels of mRNA for SK3 were significantly lower in the uterus of 17β-estradiol-treated animals than in the uterus...... of ovariectomized animals. We conclude that the SK channels are present in the endometrial epithelium, and possibly also in the myometrium of the rat uterus. Furthermore, the hormonal effect on SK3 caused by 17β-estradiol includes divergent regulation at mRNA and protein levels....

    The increase in /sup 65/Zn uptake was observed in mitochondrial, microsomal and soluble fraction of IUD-fitted horn compared to contralateral control horn and that of intact control animals. The nuclear fraction also showed higher /sup 65/Zn uptake in IUD-horn and contralateral control horn from that of intact control rats, but the contralateral control horn had higher values than sutured side. The above findings reveal that the /sup 65/Zn uptake increases in the mitochondrial, microsomal and soluble fractions due to the effect of an IUD.

    The aim of the present study was to evaluate the role of Echinacea and parsley oil some biochemical, histological and bone marrow abnormalities, induced by g-irradiation exposure. Echinacea and parsley oil were orally administrated to female rats (50 mg /100 g b.wt./ day and 0.2 ml/100g b.wt./day, respectively) 7 days before and during exposure to radiation for 3 weeks since female rats were submitted to fractionated whole body gamma-radiation 1 Gy every week up to 3 Gy total dose. The results obtained revealed that treatment with Echinacea and parsley oil induced significant amelioration to the harmful effect of radiation on red blood corpuscles (RBCs), white blood corpuscles (WBCs), haemoglobin concentration (Hb), calcium level (Ca), in addition to estradiol (E2) and progesterone (p4) hormones in serum. Moreover, the treatment with Echinacea and parsley oil diminished the increase in urea, uric acid, creatinine and alkaline phosphatase (ALP) levels recorded in the serum of irradiated rats. Our findings demonstrated that exposure to g-radiation caused an increase in the apoptotic cells, while the treatment with Echinacea and parsley oil decreased the apoptotic cells and increased the alive cells in the bone marrow of female rats. Histological observations of the ovary and uterus sections showed that radiation induced deformation in the follicular tissue, dis organization of granulosa cells, abnormal Graafian follicle which appeared without ova, haemorrhage, dilated blood vessels and vacuolation ovarian tissue. Also, the uterus of female rats showed increase in endometrium thickness, decreased muscularis thickness and muscle fibres appeared with pyknotic nuclei. All these changes were obviously improved in animals supplied with echinacea and parsley oil. It could be concluded that Echinacea and parsley oil could be useful and adjunct for maintaining the integrity of biochemical changes, restored the original histological architecture of the ovary and uterus and

    A small dermatan sulphate proteoglycan (DSPG) was extracted from rat cervices and was purified by using DEAE-Sephacel ion-exchange chromatography, gel filtration on Sepharose CL-2B and CsCl-density-gradient centrifugation. Sedimentation-equilibrium centrifugation gave a weight-average Mr of 95,000. Amino acid analysis showed a high content of aspartic acid, glutamic acid, glycine and leucine. The glycosaminoglycan chains had Mr 50,000 as determined by gel filtration. Chondroitin AC lyase and chondroitin ABC lyase digestions of these chains showed that they were composed of 75% dermatan sulphate and 25% chondroitin sulphate. Chondroitin ABC lyase digestion produced a core protein of Mr 45,000. The core protein, after treatment with HF, had Mr 37,000. Amino acid sequences of the N-terminus and a CNBr-cleavage peptide showed similarity to the sequences of core proteins of small proteoglycans of bovine and human origin, but the N-terminal glycosaminoglycan-attachment site (Ser-Gly-Ile-Ile) differed from the consensus sequence (Ser-Gly-Xaa-Gly) [Bourdon, Krusius, Campbell, Schwartz & Ruoslahti (1987) Proc. Natl. Acad. Sci. U.S.A. 84, 3194-3198]. A polyclonal antibody against the rat cervical DSPG reacted with small proteoglycans from cervices of human, mouse, dog, cow and sheep. DSPG is the major proteoglycan species present in the cervix. The amount of DSPG per cervix increases 4-fold during pregnancy, then falls precipitously within 1 day post partum. A role in cervical dilatation is postulated for this proteoglycan.

    Chlorpyrifos (CPF) is an organophosphorus pesticide widely used in agricultural applications and household environments. 6-Gingerol-rich fraction from Zingiber officinale (Ginger, 6-GRF) has been reported to possess potent anti-oxidative, anti-inflammatory and anti-apoptotic properties. Here, we investigated the protective properties of 6-GRF on CPF-induced oxidative damage and inflammation in the brain, ovary and uterus of rats. Five groups of rats containing 14 rats/group received corn oil (control), CPF (5 mg/kg), 6-GRF (100 mg/kg), CPF (5 mg/kg) + 6-GRF (50 mg/kg) and CPF (5 mg/kg) + 6-GRF (100 mg/kg) through gavage once per day for 35 days respectively. The results showed that 6-GRF protected against CPF-induced increases in oxidative stress ((hydrogen peroxide (H 2 O 2 ) and malondialdehyde (MDA)), inflammatory (myeloperoxidase (MPO), nitric oxide (NO) and tumour necrosis factor-α (TNF- α)), and apoptotic (caspase-3) markers. Also, 6-GRF improved the activities of antioxidant enzymes catalase, superoxide dismutase (SOD), glutathione peroxidase (GPx), and glutathione S-transferase (GST) as well as glutathione (GSH) level in the brain, ovary and uterus of rats exposed to CPF (p < 0.05). Overall, the protective effects of 6-GRF on CPF-induced toxicity in the brain and reproductive organs of rats may be due to its potent antioxidative, anti-inflammatory and antiapoptotic properties.

    A case of inversion of the uterus following abortion is reported. The 35-year old patient, admitted October 10, 1978 to the Medical College and Hospitals in Calcutta, India was referred by a private practitioner with a history of amenorrhea for 16 weeks, bleeding for 3 days, expulsion of the fetus 3 days earlier, and something coming down per vaginum for 2 days. The patient was para 4+0 (all full term normal deliveries) and home delivery for the last child 1 1/2 years earlier. She had a history of regular menstrual periods. Her general condition was poor. The examination revealed a gangrenous mass coming out of the vulva with a very offensive smell. There was a raw surface on which placenta like tissue was attached. No active bleeding was seen. Fundus and cervix of the uterus could not be felt. On rectal examination the uterus could not be felt, a cup-like depression was felt at the site of the uterus. The provision diagnosis was inversion of uterus following abortion. Treatment was started with sedatives and antibiotics, and arrangements were made for a blood transfusion. The vaginal mass was covered with glycerine and acriflavine gauze, and a hysterectomy was decided upon after improvement of her general condition and control of the infection. On October 14th, the patient was placed in knee chest position and posterior vaginal wall was retracted with Sims' speculum when the inverted lump was spontaneously reduced within the vagina. The inverted uterus was felt in the region of the vaginal vault. Glycerine acriflavine pack was given which was taken out and repack was given daily until the operation. The hysterectomy was performed on October 23rd. The abdomen was opened up by a transverse incision and the pelvis was explored. In the region of the uterus a cup-shaped depression was noted. Tubes and ovaries of both sides were seen hanging laterally from the cupped area. The left tube was found congested and thickened. Reduction of uterus was done by making a vertical

    Liarozole fumarate (liarozole – R85246) is a novel compound with characteristics of both aromatase inhibitor (AI) and a retinoic acid metabolism blocking agent (RAMBA). Our objective was to determine the effects of liarozole alone or in combination with tamoxifen on the N-methyl-N-nitrosourea (MNU)-induced rat mammary carcinoma model, as well as on the uterus in ovariectomized immature rats. (1) Tumor burden experiments: Animals bearing one or more tumors greater than 10 mm in diameter were treated for 56 consecutive days with 20 mg/kg or 80 mg/kg of liarozole by oral gavage, tamoxifen 100 μg/kg by subcutaneous injection, or a combination of liarozole and tamoxifen. At the end of the treatment period, total cumulative tumor volume as well as retinoic acid levels were measured. (2) Uterotrophic assay and proliferation experiments: 21-day-old ovariectomized (OVX) Sprague-Dawley rats were treated with 20 mg/kg or 80 mg/kg of liarozole by oral gavage, tamoxifen 1 mg/kg by subcutaneous injection, and combination of both for 4 consecutive days. At the end of the treatment period, uterine weight, epithelial lining cell height and indices of proliferation cell nuclear antigen (PCNA) were measured. The tumor burden experiments in rats bearing estrogen receptor (ER) positive mammary tumours showed that liarozole has a marked anti-tumour effect. In combination with tamoxifen, liarozole had neither an additive nor an antagonistic effect. However, liarozole markedly reduced the uterotrophic effects induced by tamoxifen. Liarozole's antitumor effects on ER positive mammary tumors and its protective effect on the uterus merit further studies to confirm its clinical value in combination with tamoxifen in ER positive postmenopausal breast cancer. Liarozole and other retinomimetics might also be suitable chemoprevention drugs in combination with tamoxifen because of their favorable toxicity profile

    Since its introduction in clinical practice in the 1990 s, positron emission tomography (PET), usually with {sup 18}F-fluoro-2-deoxy-D-glucose ({sup 18}F-F.D.G.), has become an important imaging modality in patients with cancer. For cervix carcinoma, F.D.G.-PET is significantly more accurate than computed tomography (CT) and is recommended for loco-regional lymph node and extra pelvic staging. The metabolic dimension of the technique provides additional prognostic information. Ongoing studies now concentrate on more advanced clinical applications, such as the planning of radiotherapy, the response evaluation after the induction of therapy, the early detection of recurrence. Technical innovations, such as PET cameras with better spatial resolution and hybrid positron emission tomography/computed tomography (PET-CT), available now on the whole territory, provide both anatomic and metabolic information in the same procedure. From the point of view of biological metabolism, new radiopharmaceutical probes are being developed. Those hold promise for future refinements in this field. This article reviews the current applications of F.D.G.-PET in patients with cervix cancer. (authors)

A 14-year-old girl with two hemiuteri lacking any communication with a single normal midline cervix and vagina. Diagnostic laparoscopy with chromopertubation to identify the anomaly and subsequent bilateral supracervical hemihysterectomies. Incidence, pathogenesis, fertility implications, and treatment options for patients with congenital defects in the upper vagina, cervix, and uterus. Based on classic embryology, the lower vagina forms from the urogenital sinus while the upper vagina, cervix, and uterus form from the müllerian ducts. If a cervix is present, then the upper vagina and uterus are also usually present and should communicate. This anomaly cannot be fully explained by traditional embryologic developmental theory. It is likely that an insult occurred between 9 weeks, when the uterovaginal canal is formed, and 12 weeks, when the müllerian ducts fuse. Copyright © 2011 American Society for Reproductive Medicine.

    Cervix cancers declined in most developed countries in recent years, but remain, the third worldwide leading cause of cancer death in women. A precise staging, based on clinical exam, an abdominal and pelvic MRI, a possible PET-CT and a possible lymph node sampling is necessary to adapt the best therapeutic strategy. In France, the treatments of tumors of less than 4 cm without nodal involvement are often based on radiotherapy followed by surgery and, whereas tumors larger than 4 cm and involved nodes are treated with concurrent chemoradiotherapy. Based on an illustrated clinical case, indications, delineation, dosimetry and complications expected with radiotherapy are demonstrated. (authors)

    The objective of this study was to investigate the effects of estrogen receptor (ER) agonists and an ER antagonist on the expression of Hedgehog genes (Indian hedgehog: Ihh; Desert hedgehog: Dhh) and Hedgehog target genes (Patched 1: Ptc1; glioma-associated oncogene homolog 1: Gli1; chicken ovalbumin upstream promoter transcription factor II: Coup-TfII) in the rat uterus. Immature female rats were administered once with 17alpha-ethynyl estradiol (EE, an ER agonist), propyl pyrazole triole (PPT, an ERalpha-selective agonist), diarylpropionitrile (DPN, an ERbeta-selective agonist), or ICI 182,780 (an ER antagonist). Expression of mRNA for Ihh, Dhh, and Ptc1 was dose-dependently downregulated by EE in the uterus of immature rats, mediated by ER as confirmed by coadministration of ICI 182,780. The mRNA expression levels of Ptc1, Gli1, and Coup-TfII were simultaneously downregulated during the period in which the mRNA expression levels of Ihh and Dhh were downregulated in the uterus after administration of EE. PPT downregulated the transcription of Ihh, Dhh, Ptc1, Gli1, and Coup-TfII, indicating that expression of these genes was regulated by the ERalpha-dependent pathway. DPN also downregulated the transcription of Ihh and Dhh, although the effect was weaker than that of PPT, indicating that the regulation of uterine Ihh and Dhh transcription was also affected by the ERbeta-dependent pathway. These results suggest that the expression of Hedgehog genes (Ihh, Dhh) and Hedgehog target genes (Ptc1, Gli1, Coup-TfII) is affected by estrogenic stimuli in the uterus of immature female rats.

    16α-[ 77 Br]bromoestradiol-17β (compound 1) has been synthesized by radiobromination of estrone enoldiacetate. Tissue uptake studies performed 1 hr after administration of compound 1 to immature or mature female rats showed uterus-to-blood ratios of 13, with nontarget tissue-to-blood ratios ranging from 0.6 to 2. Co-administration of unlabeled estradiol caused a selective depression in the uterine uptake with no effect on nontarget tissue uptake. In adult animals bearing adenocarcinomas induced by DMBA (7,12-dimethylbenz(a)anthracene), tumor-to-blood ratios of 6.3 were obtained, this uptake also being depressed in animals treated with unlabeled estradiol. The studies demonstrate that compound 1 has suitable binding properties and sufficiently high specific activity so that its uptake in estrogen target tissues in vivo is mediated primarily by the estrogen receptor. Furthermore, they suggest that this compound may be suitable for imaging human breast tumors that contain estrogen receptors

    Full Text Available Dysregulation of uterine fluid environment could impair successful reproduction and this could be due to the effect of environmental estrogens. Therefore, in this study, effect of quercetin, an environmental estrogen on uterine fluid and electrolytes concentrations were investigated under sex-steroid influence. Ovariectomised adult female Sprague-Dawley rats were given 10, 50 or 100mg/kg/day quercetin subcutaneously with 17-β estradiol (E for seven days or three days E, then three days E plus progesterone (P (E+P treatment. Uterine fluid secretion rate, Na+, Cl- and HCO3- concentrations were determined by in-vivo perfusion. Following sacrifice, uteri were harvested and levels of the proteins of interest were identified by Western blotting and Realtime PCR. Distribution of these proteins in the uterus was observed by immunofluorescence. Levels of uterine cAMP were measured by enzyme-linked immunoassay (EIA. Administration of quercetin at increasing doses increased uterine fluid secretion rate, Na+, Cl- and HCO3- concentrations, but to the levels lesser than that of E. In concordant, levels of CFTR, SLC4A4, ENaC (α, β and γ, Na+/K+-ATPase, GPα/β, AC and cAMP in the uterus increased following increased in the doses of quercetin. Co-administration of quercetin with E caused uterine fluid secretion rate, Na+, Cl- and HCO3- concentrations to decrease. In concordant, uterine CFTR, SLC26A6, SLC4A4, ENaC (α, β and γ, Na+/K+-ATPase, GPα/β, AC and cAMP decreased. Greatest effects were observed following co-administration of 10mg/kg/day quercetin with E. Co-administration of quercetin with E+P caused uterine fluid Na+ and HCO3- concentrations to increase but no changes in fluid secretion rate and Cl- concentration were observed. Co-administration of high dose quercetin (100 mg/kg/day with E+P caused uterine CFTR, SLC26A6, AC, GPα/β and ENaC (α, β and γ to increase.

    The insecticide dichlorodiphenyltrichloroethane (DDT) is a nonmutagenic xenobiotic compound able to exert estrogen-like effects resulting in activation of estrogen receptor-α (ERα) followed by changed expression of its downstream target genes. In addition, studies performed over recent years suggest that DDT may also influence expression of microRNAs. However, an impact of DDT on expression of ER, microRNAs, and related target genes has not been fully elucidated. Here, using real-time PCR, we assessed changes in expression of key genes involved in hormonal carcinogenesis as well as potentially related regulatory oncogenic/tumor suppressor microRNAs and their target genes in the uterus and ovaries of female Wistar rats during single and chronic multiple-dose DDT exposure. We found that applying DDT results in altered expression of microRNAs-221, -222, -205, -126a, and -429, their target genes (Pten, Dicer1), as well as genes involved in hormonal carcinogenesis (Esr1, Pgr, Ccnd1, Cyp19a1). Notably, Cyp19a1 expression seems to be also regulated by microRNAs-221, -222, and -205. The data suggest that epigenetic effects induced by DDT as a potential carcinogen may be based on at least two mechanisms: (i) activation of ERα followed by altered expression of the target genes encoding receptor Pgr and Ccnd1 as well as impaired expression of Cyp19a1, affecting, thereby, cell hormone balance; and (ii) changed expression of microRNAs resulting in impaired expression of related target genes including reduced level of Cyp19a1 mRNA.

    Several key predictions of a recently developed model for functional antagonism (Mackay, 1981) were experimentally tested using the rat isolated costo-uterine preparation. In the presence of the functional antagonist fenoterol (Fen), the functional constants (KAF) for carbachol and oxotremorine (Oxo) were respectively 9.9 and 3.4 fold greater than their corresponding affinity constants (KA). According to Mackay's model for functional antagonism, the higher KAF/KA ratio for carbachol indicates that this cholinoceptor agonist has a greater efficacy than Oxo. This was confirmed by using conventional pharmacological methods. As predicted from the model of functional antagonism, the plot of KAF/KA-1 against the fraction of cholinoceptors not irreversibly blocked by phenoxybenzamine (Pbz) was linear for both carbachol and Oxo and the lines of best fit crossed the axes at a point not significantly different from the origin. The value of 4.6 for the relative efficacy of carbachol to Oxo estimated from functional antagonism studies was comparable to the value of 5.6 calculated using the method of irreversible antagonism proposed by Furchgott (1966).

    What are the anatomic variants (and their frequencies) of double uterus, obstructed hemivagina and ipsilateral renal agenesis? Most cases examined (72.4%) were of the classic anatomic variant of the Herlyn-Werner-Wunderlich syndrome (with didelphys uterus, obstructed hemivagina and ipsilateral renal agenesis) but the 27.6% of cases are of a rare variant of the syndrome (with uterus septum or cervical agenesis), showing relevant clinical and surgical implications. The extreme variability of anatomic structures involved in this syndrome (both uterus, cervico-vaginal and renal anomalies) is well known, even if a complete and uniform analysis of all its heterogeneous presentations in a large series is lacking. This is a retrospective study with 87 patients referred to our third level referral center between 1981 and 2011. We analyzed the laparoscopic and chart records of 87 women, who referred to our institute with double uterus, unilateral cervico-vaginal obstruction and ipsilateral renal anomalies. Sixty-three of 87 patients had the more classic variant of didelphys uterus with obstructed hemivagina; 10/87 patients had septate bicollis uterus with obstructed hemivagina; 9/87 patients had bicornuate bicollis uterus with obstructed hemivagina; 4/87 patients had didelphys uterus with unilateral cervical atresia; 1/87 patients had bicornuate uterus with one septate cervix and unilateral obstructed hemivagina. This is a retrospective study with a long enrolling period (30 years). New insights in the anatomic variants of this rare syndrome with their relevant surgical implications.

    Torsion of a nongravid uterus is rare, as most cases of uterine torsion occur during pregnancy. We report a case of a large ovarian cyst causing uterine torsion, infarction, and rupture. A 57-year-old woman presented with acute-onset abdominal pain and increasing abdominal girth over the past year. Contrast-enhanced computed tomography (CT) demonstrated axial rotation and swirling of the uterus and the mesenteric fat, leading to a preoperative diagnosis of uterine torsion. Laparotomy confirmed that the uterine corpus had undergone a 180-degree axial rotation, and further revealed uterine wall infarction and rupture into the endometrium as well as partial decapitation of the uterus from the cervix. The swirled appearance of the uterus, radiologically similar to the "whirlpool sign" seen in bowel volvulus, is an important CT finding to recognize, especially in view of the risk of irreversible ischemic complications this uncommon entity may inflict on the uterus.

    The combinatorial effects of genistein and estrogen (E) or estrogen plus progesterone (E+P) on CFTR, AC and cAMP levels in cervix were investigated. Ovariectomised adult female rats received 50 or 100mg/kg/day genistein with E or E followed by E+P [E+(E+P)] for seven consecutive days. Cervixes were harvested and analyzed for CFTR mRNA levels by Real-time PCR. Distribution of AC and CFTR proteins in endocervix were observed by immunohistochemistry. Levels of cAMP were measured by enzyme-immunoassay. Molecular docking predicted interaction between genistein and AC. Our results indicate that levels of CFTR, AC and cAMP in cervix of rats receiving genistein plus E were higher than E-only treatment (pcervix of E and E+(E+P)-treated rats by genistein could affect the cervical secretory function which could influence the female reproductive processes.

    Preterm birth is the major cause of neonatal mortality and morbidity, and bacterial infections that ascend from the lower female reproductive tract (FRT) are the most common route of uterine infection leading to preterm birth. The uterus and growing fetus are protected from ascending infection by the cervix, which controls and limits microbial access by the production of mucus, cytokines and anti-microbial peptides (AMPs). If this barrier is compromised, bacteria may enter the uterine cavity leading to preterm birth. Using a mouse model, we demonstrate, for the first time, that viral infection of the cervix, during pregnancy, reduces the capacity of the FRT to prevent bacterial infection of the uterus. This is due to differences in susceptibility of the cervix to infection by virus during pregnancy and the associated changes in TLR and AMP expression and function. We suggest that preterm labor is a polymicrobial disease, which requires a multifactorial approach for its prevention and treatment. PMID:23752614

    Full Text Available El D-004 consiste en una mezcla de ácidos grasos que inhibe significativamente la hiperplasia prostática inducida por testosterona en roedores. El objetivo del presente estudio fue evidenciar los posibles efectos adversos sobre el ciclo estral de hembras F1 expuestas in útero al D-004. Se utilizaron ratas Sprague Dawley, distribuidas aleatoriamente en 4 grupos: un control y 3 tratados con D-004 a las dosis de 500, 750 y 1 000 mg/kg; las hembras recibieron la administración de la dosis por vía oral desde 15 días antes del apareo y hasta el fin de la lactancia. A una hembra por camada de la generación F1 se le estudió la citología vaginal y se calculó la longitud aproximada del ciclo, la cual no se vio afectada ya que no existieron diferencias significativas (p= 0,1537 entre los grupos tratados y el control. Estos resultados indican que el D-004 no reveló alteraciones del ciclo estral de las crías hembras expuestas in útero.D-004 is a mix of fatty acids inhibiting significantly Testosterone- induced prostatic hyperplasia in rodents. The aim of present paper was to demonstrate the potential side effects on estrus cycle of F1 female rats exposed in uterus to D-004. We used Sprague Dawley rats, distributed randomly in 4 groups: a control one and another three treated with D-004 at a dosage of 500, 750 and 1 000 mg/kg; in the female rats we administered the dose by mouth from the 15 days before mating, and up to breast feeding termination. In each female rat by litter of F1 generation, the vaginal cytology was studied, and we estimated the approximate length of cycle, remained un-affected since there were not significant differences (p= 0,1537 among treatment groups and the control one. These results show that D-004 fails to reveals alterations in the estrum cycle of female litters exposed in uterus.

    This paper is the report of 9 cases of anal and low rectal cancer following pelvic irradiation for cancer of uterus or cervix. This second cancer appears between the 10th and 20th year after radiotherapy, with a mean of 18,2 years. Its treatment can still be conservative for anal cancer but for low rectal tumor, abdominal resection is necessary. A statistical study has concluded that there is an excess risk for this group of patients, only for patients treated by radiotherapy for uterus cervix cancer. Those patients justify, endoscopic follow-up, especially after the 10th year with anterior rectal wall biopsies. With this attitude, these late complications should not offset the benefit of pelvic irradiation in the treatment of cancer of the uterus [fr

    Since the introduction of the Papanicolaou smear and colposcopy, cervical cancers can be diagnosed and treated easily in their preinvasive state. Although theoretically cancer of the cervix should be detected and treated before becoming invasive disease, there are still too many women who develop invasive cancer of the cervix and require radical surgery and/or radiation therapy. The management of patients with recurrent or advanced disease is difficult and challenging.36 references

    Chronic oral treatment of tetrabromobisphenol A (TBBPA) to female Wistar Han rats resulted in increased incidence of cell proliferation at 250 mg/kg and tumor formation in the uterus at higher doses. The present study was designed to test the hypothesis that disruption of estrogen homeostasis was a major mode-of-action for the observed effects. Biological changes were assessed in serum, liver, and the proximal (nearest the cervix) and distal (nearest the ovaries) sections of the uterine horn of Wistar Han rats 24 h following administration of the last of five daily oral doses of 250 mg/kg. Expression of genes associated with receptors, biosynthesis, and metabolism of estrogen was altered in the liver and uterus. TBBPA treatment also resulted in changes in expression of genes associated with cell division and growth. Changes were also observed in the concentration of thyroxine in serum and in expression of genes in the liver and uterus associated with thyroid hormone receptors. Differential expression of some genes was tissue-dependent or specific to tissue location in the uterus. The biological responses observed in the present study support the hypothesis that perturbation of estrogen homeostasis is a major mode-of-action for TBBPA-mediated cell proliferation and tumorigenesis previously observed in the uterus of TBBPA-treated Wistar Han rats. - Highlights: • Perturbation of estrogen homeostasis in TBBPA-treated female rats was investigated. • Gene expression changes were observed in the liver and uterus of these rats. • Genes associated with estrogen biosynthesis and metabolism were affected. • Genes associated with thyroid homeostasis and cell division/growth were affected. • A mechanism of uterine toxicity via endocrine disruption was indicated.

    A functioning uterus may be present in 5 to 10 % of the patients with congenital absence of the vagina. The proper treatment for these patients depends on accurate pre-operative diagnosis on whether or not a cervix is present, because the mode of operation should be selected according to the type of abnormality. Ultrasonography or X-ray CT scan will not always be useful to answer this question. We encountered a 15-year-old female with cyclic lower abdominal pain and the failure of onset of menstruation. The external genitalia were normal except for the absence of the vaginal opening. Ultrasonography and X-ray CT scan revealed the presence of both uterine corpus and hematocolpos, but no definite findings were obtained on the integrity of the cervix. By using NMR-CT scan, we found a hematocolpos, properly developed uterine cervix and corpus above it. We treated the patient by preserving the uterine function and the potential for pregnancy in the future. NMR-CT scan seems more useful in some cases for diagnosis of pelvic mass than ultrasonography and X-ray CT scan. (author)

    Preterm birth is a strong contributor to perinatal mortality, and preterm infants that survive are at risk for long-term morbidities. During most of pregnancy appropriate mechanical function of the cervix is required to maintain the developing fetus in utero. Premature cervical softening and subsequent cervical shortening are hypothesized to cause preterm birth. Presently, there is a lack of understanding of the structural and material factors that influence the mechanical function of the cervix during pregnancy. In this study we build finite element (FE) models of the pregnant uterus, cervix, and fetal membrane based on magnetic resonance imagining (MRI) data in order to examine the mechanical function of the cervix under the physiologic loading conditions of pregnancy. We calculate the mechanical loading state of the cervix for two pregnant patients: 22 weeks gestational age with a normal cervical length and 28 weeks with a short cervix. We investigate the influence of 1) anatomical geometry 2) cervical material properties, and 3) fetal membrane material properties, including its adhesion properties, on the mechanical loading state of the cervix under physiologically relevant intrauterine pressures. Our study demonstrates that membrane-uterus interaction, cervical material modeling, and membrane mechanical properties are factors that must be deliberately and carefully handled in order to construct a high quality mechanical simulation of pregnancy.

    Congenital abnormalities of the uterus and the cervix are rare in horses, often associated with infertility, despite normal ovarian activity and sexual behaviour. An abnormality of the cervix in a 5-year-old jennet with a history of infertility was described. Clinical and ultrasound examination of the genital tract showed a normal development of the uterus with regular cyclic activity in both the ovaries. Vaginoscopy revealed a normal development of the vagina and a cervix deviated on the left side of the vagina by a thick dorsoventral fold. The lateral deviation was permanent in any stage of oestrus cycle. Furthermore, the cervical os was narrow and digital penetration was not realizable. Using a 5-mm catheter, the full penetration was not possible even during oestrus; moreover, the inoculation of fluid could be revealed in uterus by ultrasound (fluid was not present before inoculation), demonstrating a minimal patency. An abnormal and permanent lateral displacement of a stenotic cervix was suspected as the primary cause of infertility in the jennet. © 2015 Blackwell Verlag GmbH.

    Torsion of a nongravid uterus is extremely rare. Most cases of uterine torsion occur during pregnancy. Here we report a case of nongravid uterus torsion with a large adnexal mass. A 73-year-old woman presented at the emergency room with acute abdominal pain. A preoperative diagnosis of torsion of an ovarian cyst was made and laparotomy was performed. The left ovary was twisted 360 degrees in a clockwise rotation, and the uterine corpus had also undergone a 360 degrees rotation. Total abdominal hysterectomy and bilateral salpingo-oophorectomy were carried out. Although a preoperative diagnosis of uterine torsion was not possible, it is noteworthy that in the contrast-enhanced magnetic resonance images the uterine cervix was intensely enhanced, while the uterine corpus was not. This is the first report to show the magnetic resonance imaging findings of a twisted uterus. Copyright (c) 2007 S. Karger AG, Basel.

    Pyometra, a life-threatening bacterial infection of the uterus, is classified as open or closed depending on the functional patency of the cervix i.e. presence or absence of vaginal discharge. In closed cervix pyometra, pus and bacterial products accumulate in the uterus, which is thought to induce a more severe illness. The aim of this study was to investigate whether disease severity or outcome differed in dogs with open or closed cervix pyometra. Prospectively collected data from 111 female dogs diagnosed with pyometra at the University Animal Hospital, Swedish University of Agricultural Sciences, Uppsala, intermittently during 2005-2012 was analyzed. Seventy-two dogs (65%) had open cervix, whereas 39 dogs (35%) had closed cervix. Differences between the two groups were explored by Wilcoxon Two Sample Test for continuous variables and Chi-square or Fisher's exact test for categorical variables. P cervix the median age was 9.0 years and the median weight 26.0 kg. In dogs with closed cervix the median age was 9.6 years and the median weight 25.0 kg, with no significant differences between the groups (p = 0.69 and 0.24, respectively). Five dogs (4.5%) died, all with open cervix, and 16 dogs (14%) had complications. The general physical condition was moderately or severely depressed in 30% (21/71) of dogs with open cervix (severely depressed in 4 dogs, moderately depressed in 17 dogs) and in 56% (22/39) of dogs with closed cervix (severely depressed in 3 dogs, moderately depressed in 19 dogs). The general physical condition was mildly depressed in 41 dogs with open cervix and 16 dogs with closed cervix, whereas it was normal in nine dogs with open cervix and one dog with closed cervix. None of the included dogs had very severely depressed general physical condition or were non-responsive. Leukocytosis, neutrophilia, monocytosis and moderately to severely depressed general condition was more commonly found in dogs with closed cervix (p = 0.003, p

    The objective of the study was to investigate the angioarchitectonics and the functional morphology of the vessels of the cervix and to clarify the role of structural features of these vessels in preventing hemorrhaging in parturition during cervical dilatation. Cervixes uteri were obtained from corpses of 30 women of various ages and 5 ablated at labor. Series of histotopographical specimens of the cervixes were processed using histological and histochemical methods. Peculiar features of the angioarchitectonics, histotopography and structure of cervical vessels were encountered. Arteries penetrating the cervix are surrounded by tight muffs of anastomizing veins that are closely adjacent to the arteries. In other cases, the arteries are located within the lumen of veins--"vessels within vessels". Cervical arteries make up subendocervical convolutions. During pregnancy, smooth muscle "cushions" develop in the vessels. The cervix is pierced by a network of veins that divide the cervical tissue into separate stromal "lobules". This peculiar vascular architecture might be important structural basis of the vascular hemostatic mechanism in the neck of the uterus triggered by labor. It prevents vessel rupture, hemorrhaging and amniotic fluid and air embolism during cervical dilatation. The venous network that passes through the cervix makes it easy for the separate stromal "lobules" of the cervix to move relative to each other during cervical dilatation.

    Full Text Available Adenoid cystic carcinoma of uterine cervix is a rare tumor. Its origin is debatable. It has a high incidence in postmenopausal women but rarely can develop in patients under 40. An association with squamous cell carcinoma has been described. We report a case of adenoid cystic carcinoma of the endocervical canal with foci of squamous cell carcinoma in a 34-year-old suffering from menorrhagia associated with blood-stained vaginal discharge. Per vaginum and per speculum examination revealed a growth. Cervical biopsy showed bits of tissue, suggesting adenoid cystic carcinoma. Patient was operated upon and uterus with cervix sent for histopathological examination. We report this case because of its rarity, particularly in young patients, with description of illustrative pathology and discussion on the histological diagnosis.

    Arterial venous malformations (AVM) of the uterus are uncommon entities and should be considered in patients who present with profuse genital bleeding. There are two types of uterine AVM: acquired and congenital. Acquired uterine AVMs are conformed by communications between the uterine arteries and the myometrial veins, and are caused by an iatrogenic event or a pathological condition. Congenital AVMs are the result of abnormal development of primitive vessels that result in connections between pelvic arteries and veins in the uterus without an interconnecting capillary bed. Ultrasonography is a noninvasive diagnostic method able to demonstrate and characterize AVMs of the uterus. AVM in the pelvis may be noted incidentally by computed tomography (CT) of the pelvis, and magnetic resonance imaging (MRI) is frequently used to confirm and further characterize the sonographic findings of uterine AVM. Catheter angiography and embolization are very effective in defining the vascular anatomy and treating uterine vascular abnormalities.

    This study was designed to analyze characteristic features of the human uterus by using a 0.5 Tesla super-conducting magnet. Relative square ratios of the endometrium and the junctional zone to the uterine body were measured during menstrual cycle with a computed image analyser. Nine healthy volunteers aged 21 to 30 years underwent magnetic resonance imaging (MRI) in the proliferative, secretory, and menstrual phases. Relaxation times of the endometrium, junctional zone, and myometrium were determined. The relative ratio of the endometrium to the uterine body was 13.8% in the proliferative phase, 17.9% in the secretory phase, and 8.0% in the menstrual phase. The ratio of the junctional zone decreased from 26.6% in the proliferative phase to 23.4% in the secretory phase, and increased to 35.0% in the menstrual phase. Relaxation times of the endometrium and junctional zone were the shortest in the menstrual phase. For the myometrium, T 1 values showed the same tendency. T 2 values were the shortest in the proliferative phase. MRI was also performed in 39 patients with hydatidiform (one), myoma uteri (11), adenomyosis uteri (one), carcinoma of the uterine body (3), and carcinoma of the uterine cervix (23). Myoma nodule without degeneration appeared at low intensity, and had the shortest T 1 and T 2 values. Myoma uteri with degeneration had an increased intensity and larger T 1 and T 2 values. Adenomyosis uteri showed a diffuse low intensity with high intensity spots. Malignant lesions of both the uterine body and cervix showed a high intensity on T 2 -weighted image and similar T 1 and T 2 values. These T 1 and T 2 values were, however, shorter than tissue of unmarried normal women. MRI was considered useful for the observation of menstrual cyclic and quantitative change in the human physiologic uterus, as well as for the differentiation of malignant from benign uterine diseases.

    Dimethyl sulfoxide (DMSO) is a widely used solvent and cryoprotectant that can cause impaired blood flow, reduction in intracranial pressure, tissue edema, inflammatory reactions, inhibition of vascular smooth muscle cell migration and proliferation, processes which can lead to atherosclerosis of the coronary, peripheral and cerebral circulation. Although the adverse effects are rare when DMSO is administered in clinically established concentrations, there is no safe antagonist for an overdose. In this work, we treated isolated spontaneous and calcium-induced contractile active rat uteri (Wistar, virgo intacta), with DMSO and fullerenol C{sub 60}(OH){sub 24} nanoparticle (FNP) in DMSO. FNP is a water-soluble derivative of fullerene C{sub 60}. Its size is a 1.1 nm in diameter and is a very promising candidate for a drug carrier in nanomedicine. FNP also displays free radical scavenging activity. DMSO decreased both spontaneous and calcium-induced contractions. In contrast, FNP only decreased spontaneous contraction. FNP decreased copper-zinc superoxide dismutase activity and prevented the DMSO-induced increase in glutathione reductase activity. Atomic force microscopy detected that FNP aggregated with calcium ions. Our results indicate that FNP has properties that make it a good candidate to be a modulator of DMSO activity which could minimize side effects of the latter.

    Malignant mixed Mullerian tumour is a rare gynaecological tumour commonly presenting with vaginal bleeding, abdominal pain or mass in the uterine cavity, cervix or vagina. The neoplasms are commonly seen in postmenopausal women although it has been observed in younger women. Ovaries and the corpus of the uterus are commonly involved, whereas involvement of the cervix and vagina is rare. A 37 year-old Tanzania lady para 7 with a previous history of two genital polypectomies presented with history of recurrent vaginal mass which was associated with abnormal vaginal bleeding and foul smelling discharge. Vaginal examination revealed a prolapsed uterus with giant fungating cervical mass which was ulcerated, friable, and bled easily on touch. Impression was grade three uterine prolapse with infected cervical polyp/cervical sarcoma. Excision of the tumour through trans-vaginal hysterectomy was performed, no lymphadenopathy was found, no adnexa abnormalities, and no involvement of the vaginal wall. Histological diagnosis of Malignant mixed Mullerian tumour of the cervix was made. Patient recovery was unremarkable; however she was lost to follow up. The patient's mass was initially suspected to be prolapsed uterus with decubitus ulcer but the histological results were of a malignant condition. Lack of clear management guidelines for some rare mixed tumours remains a challenge for clinicians in low resource settings.

    Preterm birth is a strong contributor to perinatal mortality, and preterm infants that survive are at risk for long-term morbidities. During most of pregnancy, appropriate mechanical function of the cervix is required to maintain the developing fetus in utero. Premature cervical softening and subsequent cervical shortening are hypothesized to cause preterm birth. Presently, there is a lack of understanding of the structural and material factors that influence the mechanical function of the cervix during pregnancy. In this study we build finite element models of the pregnant uterus, cervix, and fetal membrane based on magnetic resonance imagining data in order to examine the mechanical function of the cervix under the physiologic loading conditions of pregnancy. We calculate the mechanical loading state of the cervix for two pregnant patients: 22 weeks gestational age with a normal cervical length and 28 weeks with a short cervix. We investigate the influence of (1) anatomical geometry, (2) cervical material properties, and (3) fetal membrane material properties, including its adhesion properties, on the mechanical loading state of the cervix under physiologically relevant intrauterine pressures. Our study demonstrates that membrane-uterus interaction, cervical material modeling, and membrane mechanical properties are factors that must be deliberately and carefully handled in order to construct a high quality mechanical simulation of pregnancy.

    The 'Standards, Options and Recommendations'(SOR) project, started in 1993, is a collaboration between the National Federation of the French Cancer Centres (FNCLCC), the 20 French Cancer Centres (CRLCC) and specialists from French public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health and outcome for cancer patients. The methodology is based on literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. To update, according to the methodology of SOR, the Standards, Options and Recommendations for the management of patients with cancer of the cervix, and in particular, the place of concomitant radio-chemotherapy. Data have been identified by a literature search using Medline (to April 1999) and the personal reference lists of experts. Once the guidelines were defined, the document was submitted for review to independent national and international reviewers and to the medical committees of the CRCC. The principle recommendations concerning the place of radio-chemotherapy in the treatment of cancer of the cervix are 1) the available data shows a significant increase in local control (level of evidence A) and of overall survival (level of evidence B1)following concomitant radio-chemotherapy as compared to radiotherapy alone or the combination of radiotherapy-hydroxyurea. For stages IB, IIA, proximal IIB with bad prognostic factors (tumour size greater than 4 cm and/or invasion of pelvic nodes and/or microscopic invasion of the parametrium) and without lumbo-aortic nodal invasion, concomitant radio-chemotherapy can be considered as standard treatment. This benefit is less clear for stages distal IIB, III and IVA without para-aortic nodal invasion (level of evidence C) and must be confirmed (expert agreement). 2) the toxicity of radio-chemotherapy is essentially hematologic and

    Although cervical pregnancy and placenta previa, in which the embryo and placenta embed in or adjacent to the cervix, are life-threatening complications that result in massive bleeding and poor pregnancy outcomes in women, the incidence of these aberrant conditions is uncommon. We hypothesized that a local molecular mechanism is normally in place to prevent embryo implantation in the cervix. The ovarian hormones progesterone (P(4)) and estrogen differentially direct differentiation and proliferation of endometrial cells, which confers the receptive state for implantation: P(4) dominance causes differentiation of the luminal epithelium but increases stromal cell proliferation in preparation of the uterus for implantation. In search for the cause of cervical nonresponsiveness to implantation, we found that the statuses of cell proliferation and differentiation between the uterus and cervix during early pregnancy are remarkably disparate under identical endocrine milieu in both mice and humans. We also found that cervical levels of progesterone receptor (PR) protein are low compared with uterine levels during this period, and the low PR protein levels are attributed to elevated levels of microRNA(miR)-200a in the cervix. These changes were associated with up-regulation of the P(4)-metabolizing enzyme 20α-hydroxysteroid dehydrogenase (200α-HSD) and down-regulation of its transcriptional repressor signal transducer and activator of transcription 5 in the cervix. The results provide evidence that elevated levels of miR-200a lead to down-regulation of P(4)-PR signaling and up-regulation of (200α-HSD) in the cervix, rendering it nonresponsive to implantation. These findings may point toward not only the physiological but also the pathological basis of the cervical milieu in embryo implantation.

    Purpose: To discuss a variety of technical and clinical issues concerning the management of carcinoma of the uterine cervix. Radiation therapy plays a central role in the management of patients with invasive carcinoma of the uterine cervix. Although survival rates are high for patients with small volume disease, clinicians continue to search for approaches that might improve treatment results for patients who have bulky central disease, evidence of regional dissemination or other factors associated with a high rate of disease recurrence. New technical approaches have contributed to controversy about the best means of optimizing therapeutic ratio. This course will review current approaches to the management of cervical cancer. Technical aspects of intracavitary and external beam treatment will be emphasized. Problems with brachytherapy dose specification will be discussed as will technical factors that may influence the incidence of treatment-related complications. Current understanding of the natural history of disease and of clinical factors that influence the rate of disease recurrence will be reviewed, including the importance of tumor volume, lymph node involvement, and histologic type on natural history and prognosis. The possible role of controversial methods of clinical evaluation such as lymphangiography and surgical staging will be discussed. Some of the more controversial aspects of treatment including the indications of radiation therapy vs. surgical therapy for stage IB disease, the role of extended field therapy, postoperative therapy, adjuvant hysterectomy, and neoadjuvant or concurrent chemotherapy will be discussed. Conclusions from the recent NCI consensus conference on cervical cancer will be reviewed

    Full Text Available Malignant mixed Mullerian tumors are composed of a mixture of sarcoma and carcinoma. The carcinomatous element is usually glandular, whereas the sarcomatous element may resemble normal endometrial stroma (homologous or so-called carcinosarcoma. Here, we present a homologous type of malignant mixed Mullerian tumor of the uterus that presented as a cervical mass. We describe a 55-year-old patient who had a cervical mass arising from the uterus. We performed total abdominal hysterectomy and bilateral salpingo-oophorectomy and surgical staging (including (peritoneal washings, suspicious areas or peritoneal surfaces sampled, infracolic omental sampling, pelvic and paraaortic lymph node sampling, and appendectomy. Carcinosarcomas of the uterine cervix are extremely rare, and when a post-menopausal woman with a cervical mass is admitted to the gynecology clinic, the physician should keep in mind that the mass might be a carcinosarcoma.

    From May 1991 through September 1992, a total of 17 previously untreated patients with invasive uterine cervix cancer and with intact uterus were treated with mid-dose rate intracavitary therapy administered with a Selectron. Early primary tumor responses for all patients were complete. No acute or subacute radiation injury was observed except one patient with aplastic anemia who developed rectal ulcer. Two patients of Stage IIIb died from tumor because of local, paraaortic lymph node and distant metastases. Our early experience concluded that Selectron MDR can be used for cervix cancer patients as safely and effectively as our previously used high-dose rate machine. (author).

    Lipoleiomyomas of the uterus are extremely rare benign neoplasm that can be difficult to differentiate from benign cystic ovarian teratomas. Only a few pure lipomas of the uterus have been documented. We presented a case of lipoleiomyoma of the uterus, in which sonography and computed tomography were performed, but because of its rarity, and confusion with more common uterine leiomyoma and ovarian dermoid tumor, preoperative diagnosis was not suggested. To our best knowledge, this is the first case of uterine lipoleiomyoma in Korea

    Human uterus transplantation (UTx) is currently under investigation as a treatment for uterine infertility. Without a uterus transplant, the options available to women with uterine infertility are adoption or surrogacy; only the latter has the potential for a genetically related child. UTx will offer recipients the chance of having their own pregnancy. This procedure occurs at the intersection of two ethically contentious areas: assisted reproductive technologies (ART) and organ transplantation. In relation to organ transplantation, UTx lies with composite tissue transplants such as face and limb grafts, and shares some of the ethical concerns raised by these non-life saving procedures. In relation to ART, UTx represents one more avenue by which a woman may seek to meet her reproductive goals, and as with other ART procedures, raises questions about the limits of reproductive autonomy. This paper explores the ethical issues raised by UTx with a focus on the potential gap between women's desires and aspirations about pregnancy and the likely functional outcomes of successful UTx. © 2011 Blackwell Publishing Ltd.

    We tested the hypothesis that the uterus of virgin heifers and pregnant cows possessed a resident microbiome by 16S rRNA gene sequencing of the virgin and pregnant bovine uterus. The endometrium of 10 virgin heifers in estrus and the amniotic fluid, placentome, intercotyledonary placenta, cervical lumen, and external cervix surface (control) of 5 pregnant cows were sampled using aseptic techniques. The DNA was extracted, the V4 hypervariable region of the 16S rRNA gene was amplified, and amplicons were sequenced using Illumina MiSeq technology (Illumina Inc., San Diego, CA). Operational taxonomic units (OTU) were generated from the sequences using Qiime v1.8 software, and taxonomy was assigned using the Greengenes database. The effect of tissue on the microbial composition within the pregnant uterus was tested using univariate (mixed model) and multivariate (permutational multivariate ANOVA) procedures. Amplicons of 16S rRNA gene were generated in all samples, supporting the contention that the uterus of virgin heifers and pregnant cows contained a microbiome. On average, 53, 199, 380, 382, 525, and 13,589 reads annotated as 16, 35, 43, 63, 48, and 176 OTU in the placentome, virgin endometrium, amniotic fluid, cervical lumen, intercotyledonary placenta, and external surface of the cervix, respectively, were generated. The 3 most abundant phyla in the uterus of the virgin heifers and pregnant cows were Firmicutes, Bacteroidetes, and Proteobacteria, and they accounted for approximately 40, 35, and 10% of the sequences, respectively. Phyla abundance was similar between the tissues of the pregnant uterus. Principal component analysis, one-way PERMANOVA analysis of the Bray-Curtis similarity index, and mixed model analysis of the Shannon diversity index and Chao1 index demonstrated that the microbiome of the control tissue (external surface of the cervix) was significantly different from that of the amniotic fluid, intercotyledonary placenta, and placentome tissues

    Imaging of uterine cervix carcinoma has evolved during the last decade. Recent developments in magnetic resonance imaging have expanded the role of MRI in evaluating the pathology of uterine cervix carcinoma. MRI is now the modality of choice for tumor staging, evaluating tumor response to treatment, diagnosing recurrences and for evaluating pregnant patients. MRI images will soon be used to calculate dosimetry for brachytherapy with matching and fusion software. (author)

    The World Health Organization (WHO) defines PEComas as mesenchymal tumors composed of histologically and immunohistochemically distinctive perivascular cells. Uterus is the most common site of a subgroup of PEComas not otherwise specified(NOS). PEComas of the uterine cervix are extremely rare, and only thirteen cases have been described in the English literature to date. In this review, we summarize the available data concerning diagnostics, immunohistochemical analysis, genetics and treatment of cervical PEComas. Radical hysterectomy with bilateral salpingooophorectomy is the best surgical approach available. Adjuvant therapy in its present form is not efficient. Therefore, further studies are needed to evaluate the newest treatment strategies. Copyright © 2016 Elsevier GmbH. All rights reserved.

    Background: There is growing interest in diffusion weighted magnetic resonance imaging (MRI) of cervical carcinoma but normal uterine appearances and effects of the oral contraceptive pill (OCP) have not been described. Purpose: To establish apparent diffusion coefficient (ADC) values for normal regions of uterus, determine the effect of the OCP on these values, and compare them with ADCs from cervical cancer. Material and Methods: Twenty-seven premenopausal women (19 taking the OCP) with cervical intraepithelial neoplasia (CIN) were studied with T2W and diffusion weighted MRI (DW-MRI). Regions of interest were drawn on ADC maps by visual matching with T2W images on different zones of the uterus and values compared between women not taking and taking the OCp.A further group of 25 women with clinically obvious tumors of the cervix were also studied with T2W and DW-MRI and ADC values of tumor were compared with ADC values of cervical epithelium and stroma. Results: The ADC values of adjacent zones of the uterus and cervix were significantly different from one another (P<0.001). The junctional zone was seen as a band of restricted diffusion between endometrium and outer myometrium. The ADC value of the junctional zone of the uterus was significantly greater (P<0.001) in patients taking the OCP than those patients not taking the OCp.There was no significant affect of the OCP on the ADC values of other uterine zones. Conclusion: The zonal anatomy of the uterus is well demonstrated by DW-MRI with hormonal effects secondary to the OCP affecting junctional zone alone. ADC of cervical tumor is significantly different to cervical epithelium and stroma indicating a role in cervical cancer detection and local staging

    2006-01-01

    Background: Simultaneous platinum-based radiochemotherapy is the standard of care for patients with advanced or node-positive cancer of the uterine cervix. A large body of literature concerning therapy-related acute and late morbidity is available. Chemoradiation-associated necrosis of the uterus has not been described so far. Case Report: Two patients are reported who were treated by combine chemoradiation between 2004 and 2005 for histologically confirmed cervical cancer following laparoscopic staging. Both patients were diagnosed with squamous cell cancer of the cervix FIGO stage IIB (T2b pN1 pM1 LYM G2) and FIGO IIIA (T3a pN1 MO G2), respectively. External-beam radiotherapy was applied in a 3-D-planned four-field technique, covering pelvic lymph nodes and primary tumor. Simultaneously, cisplatin was given to both patients. Following chemoradiation, both patientsdeveloped pelvic pain and an elevation of C-reactive protein (CRP) in the presence of a normal leukocyte count. Both patients underwent relaparoscopy, and necrosis of the uterus combined with partial necrosis of the bladder was diagnosed in patient 1. Patient 1 underwent total supralevatoric exenteration and patient 2 laparoscopically assisted hysterectomy withbilateral salpingo-oophorectomy. Conclusion: In patients with persisting or incident pelvic pain, questionable findings in imaging techniques and/or elevated inflammation parameters following completion of chemoradiation for cervical cancer, differential diagnosis should include radiogenic necrosis of the uterus and other pelvic organs. Laparoscopy is an ideal technique to exclude or confirm this diagnosis. (orig.)

O útero e as tubas uterinas foram colhidos para avaliação histomorfométrica e histoquímica. A altura do epitélio da ampola, tanto no proestro-estro quanto no metaestro-diestro, elevou-se com a administração de tiroxina, tornando-se semelhante à do istmo. O hipertireoidismo aumentou a secreção PAS positiva e de mucossubstâncias ácidas do infundíbulo na fase estrogênica, igualando-a à do istmo. A parede uterina apresentou-se mais espessa na fase estrogênica, resultado da ação conjunta da tiroxina no endométrio e no miométrio.

    Full Text Available Abstract Background Alterations in the normal sequence of development of müllerian ducts lead to a wide spectrum of reproductive tract abnormalities. A rare form of lack of development, regarding a short tract of the müllerian ducts, leads to the isolated agenesis of the uterine cervix. Anomalies identified among patients with müllerian agenesis include skeletal deformities (i.e., scoliosis of the spine and Klippel-Feil anomaly. Case presentation A 46 years old woman presenting cyphoscoliosis and very low stature (120 cm – 3,93 feet, came to our observation for acute pelvic pain; she also reported primary amenorrhoea associated with cyclic pelvic pain. Clinical and imaging evaluation, evidenced a blind vaginal duct of normal length, left cystic adnexal mass, and enlarged uterus with hematometra. FSH, LH, 17β estradiol and CA-125, karyotype and radiographic study of limbs and vertebral column were also evaluated. At laparotomy, a left ovarian cyst was found. Uterus ended at the isthmus; under this level a thin fibrous tissue band was found, joining the uterus to the vagina. Uterine cervix was replaced by fibrous tissue containing some dilated glands lined with müllerian epithelium. Karyotype resulted 46, XX. The described skeletal deformity, were consistent with Klippel-Feil syndrome. Conclusion We report a case of congenital scoliosis associated with müllerian agenesis limited to uterine cervix, association thus far seen only among patients with Mayer-Rokitansky-Kuster-Hauser syndrome (utero-vaginal agenesis. This case report supports the necessity to evaluate, for accompanying müllerian anomalies, all cases of congenital structural scoliosis in view of the possibility for many müllerian development abnormalities, if timely diagnosed, to be surgically corrected.

    The choice of treatment in carcinoma of the cervix is best decided after careful individual appraisal has been carried out. For best results, a long-term view must be agreed upon initially and careful followup by the same team is obligatory. At present, surgery, radiation therapy, and a combination of these two modalities have been employed successfully to manage carcinoma of the cervix. To a great extent, the facilities, the experience, and the interest of the personnel involved influence the type of therapy that will be employed. Generally speaking, the choice of treatment is determined primarily by the stage of the disease process. Radical surgery in the management of patients with Stage I and Stage II-A carcinoma of the cervix must be planned to include within the en bloc dissection the uterus, tubes, ovaries, and regional lymph node drainage from those organs. Therefore, a radical lymphadnectomy is an integral and important part of the overall management program when radical surgery is performed. In most institutions, radiation therapy is used most frequently to treat carcinoma of the cervix in Stages I and II-A. The data from various institutions indicate significant survival potential from radiation therapy treatment programs that are appropriately devised. In Stages I and II-A the complications are minimal in character (primarily proctitis and cystitis); generally, they involve a potential incidence of about six percent

    Full Text Available Liza Johannesson, Stina Järvholm Department of Obstetrics and Gynecology, Sahlgrenska Academy, University of Gothenburg, Sahlgrenska University Hospital, Gothenburg, Sweden Abstract: Even if reproductive medicine has been remarkably successful during the past few decades, with the introduction of in vitro fertilization in the late 1970s and intracytoplasmic sperm injection in the early 1990s, it has been repeatedly mocked by infertility due to an absolute uterine factor. No treatment has been available for the women suffering from an absent or dysfunctional uterus, in terms of carrying a pregnancy. Approximately one in 500 women suffer from absolute uterine infertility, and the option so far to become a mother has been to either adopt or utilize gestational surrogacy. As of today, a total of eleven cases of human uterus transplantations have been reported worldwide, conducted in three different countries. The results of these initial experimental cases far exceed what might be expected of a novel surgical method. Many more uterus transplantations are to be expected in the near future, as other research teams’ preparations are being ready to be put into clinical practice. In this review, we summarize the current worldwide experience of uterus transplantation as a treatment of absolute uterine factor infertility and the future prospects of human uterus transplantation.

    To apply 3D multifrequency MR elastography (3DMMRE) to the uterus and analyse the viscoelasticity of the uterine tissue in healthy volunteers considering individual variations and variations over the menstrual cycle. Sixteen healthy volunteers participated in the study, one of whom was examined 12 times over two menstrual cycles. Pelvic 3DMMRE was performed on a 1.5-T scanner with seven vibration frequencies (30-60 Hz) using a piezoelectric driver. Two mechanical parameter maps were obtained corresponding to the magnitude (vertical stroke G* vertical stroke) and the phase angle (φ) of the complex shear modulus.

    To apply 3D multifrequency MR elastography (3DMMRE) to the uterus and analyse the viscoelasticity of the uterine tissue in healthy volunteers considering individual variations and variations over the menstrual cycle. Sixteen healthy volunteers participated in the study, one of whom was examined 12 times over two menstrual cycles. Pelvic 3DMMRE was performed on a 1.5-T scanner with seven vibration frequencies (30-60 Hz) using a piezoelectric driver. Two mechanical parameter maps were obtained corresponding to the magnitude (vertical stroke G* vertical stroke) and the phase angle (φ) of the complex shear modulus. On average, the uterine corpus had higher elasticity, but similar viscosity compared with the cervix, reflected by vertical stroke G* vertical stroke {sub uterine} {sub corpus} = 2.58 ± 0.52 kPa vs. vertical stroke G* vertical stroke {sub cervix} = 2.00 ± 0.34 kPa (p < 0.0001) and φ {sub uterine} {sub corpus} = 0.54 ± 0.08, φ {sub cervix} = 0.57 ± 0.12 (p = 0.428).

    reduction in cervical cancer mortality is the ultimate goal of the screening. Quality of death certificate reports has been improved over time, but they are still inaccurate, making it difficult to assess time trends in mortality. to evaluate the accuracy of the topographic coding of causes of death and to estimate the mortality time trend for cervical cancer through the method of incidence-based mortality (IBM) using cancer registry (CR) data. from the mortality registry (MR), we extracted data on deaths for cervix uteri cancer, corpus uteri cancer, and uterus cancer not otherwise specified (NOS) referred to residents in Reggio Emilia (Emilia-Romagna Region, Northern Italy) from 1997 to 2013. Deaths were checked with the CR to verify the topographical site of the primary tumour. Furthermore, by using CR data, we constructed a cohort of incident cervical cancer cases diagnosed between 1997 and 2009 with a 5-year follow-up. We calculated cause-specific IBM (excluding ovary) and IBM for all cause, crude and standardized, and annual percentage change (APC). out of 369 deaths for uterine cancer, 269 were reported in the RT: 32 for cervix uteri cancer, 76 for corpus uteri cancer, 161 for uterus cancer NOS. 28 of the 32 persons who died for cervical cancer were incidents for cervix uteri cancer. 63 of the 76 who died for corpus uteri cancer were incidents for corpus uteri cancer. Of the 161 who died of uterus cancer NOS, 80 were incidents for corpus uteri cancer, 45 for cervix uteri cancer, 28 for uterus cancer NOS, 5 for vagina cancer, and 3 for cancer of other non-specified organs. Applying these proportions of misclassification, we can estimate that the real number of cervical cancer deaths is 2.4 folds the number of cases reported in the MR as cervical cancer. IBM for all causes decreased significantly over the years (APC: -9.5; 95%CI -17.1;-1.1); cause-specific IBM decreases, but not significantly (APC: -5.1; 95%IC -16.1;+7.3). There is no improvement in survival (r

    Cf-252 is an isotope that can easily be afterloaded into available gynecological applicators and used for bulky cervix, uterus or vaginal cancer therapy. It is economical, time and cost effective in use, and can be applied to the therapy of many patients throughout the world. It is more effective for neutron therapy than machine fast neutron therapy and is the only form of neutron therapy producing consistent complication-free 5-year cure of advanced cancers currently available. Cf-252 is an isotope for modern gynecological tumor therapy for the future. Isodose curves for Cf-252 implants revealed dose distributions conforming well to tumor. (orig.) [de

    Anemia is very commonly seen in most of the malignancies including cancer cervix. Anemia has long been reported to adversely affect the efficacy of radiation treatment in cervical cancer. At our center, carcinoma cervix accounts for approximately 8-10% of all malignancies. The objective of this study is to see the impact of anemia in the treatment of cancer cervix. In the present study, we collected data of treatment results of FIGO stage II and III cancer cervix patients retrospectively treated in years of 2009-10. We have tried to assess the outcome of results in patients whom haemoglobin (Hb) level < 10 gm/dl and e''10 gm/dl. Out of 200 patients of disease with baseline Hb less than 10 gm/dl, 80(40%) patients had residual disease after 4 weeks of completion of treatment. Out of 168 patients with baseline Hb more than 10 gm/dl, 42(25%) had residual disease (p-0.0012 i.e highly significant). Our study shows that there is a good disease control at local site in patients with higher pretreatment Hb level. Effect of pretreatment Hb on treatment outcome in terms of overall survival, disease free survival, and local relapse free survival along with effect on corrective measures should be studied in detail.

  14. Development of Transvaginal Uterus Amputation Device for Laparoscopic Hysterectomies in Gynecologic Surgeries

    2015-01-01

    Full Text Available Hysterectomy, that is removal of uterus, is one of the most common major operations in gynecologic surgeries. Laparoscopy technique is preferred in hysterectomy because of its advantages such as lower intra-operative blood loss, decreased surrounding tissue/organ damage, less operating time, lower postoperative infection and frequency of fever, shorter duration of hospitalization and post-operative returning time to normal activity. During total laparoscopic hysterectomy, first uterine vessels and ligaments are cauterized respectively, and then cervicovaginal connections are cauterized and coagulated to remove uterus completely. Uterine manipulators are used during laparoscopy to maximize the endoscopic vision of surgeons by moving related organs. However, conventional uterine manipulators have important drawbacks particularly to move uterus in three dimensions and to show cervicovaginal landmark during laparoscopic circular cauterization and amputation of the uterine cervix. A new transvaginal uterine manipulator may overcome these two important drawbacks of these currently available devices. For this reason, a3D scanned technique was used to get uterus sizes and computer aided design software is used in designing of the new manipulator and then 3D printer was used in prototyping. Special light emitting diodes (LEDs were mounted on the cervical cap of the manipulator to guide light beams from inside of cervicovaginal tissue to abdominal cavity to facilitate the visualization of tissue landmarks. Moreover, performances of different caps and LED systems will be evaluated. Furthermore, after integration of self-cutting and self-suturing mechanisms into our system, final prototype will be produced by using titanium which is biologically and mechanically appropriate. Therefore, aim of this study was to design and produce a new uterine manipulator with three dimensional movements, LED illumination, self-cutting and self-suturing systems to facilitate

    Magnetic Resonance Imaging (MRI), a non invasive procedure, is taking a place of growing importance as a means of radiological exploration. Its use in uterine pathologies has shown considerable developments. This requires an excellent knowledge of the normal and pathological aspects of the uterus. In fact it exists a zonal anatomy of the uterus which varies according to hormonal impregnation and this is very well seen by MRI. MRI gives excellent results in the diagnosis and study of different uterine pathologies. The radiological appearance of leiomyomas differs depending on the presence or not of degenerative changes within them. Uterine adenomyosis is also well studied by MRI. Lastly different studies in the literature have shown MRI to be a reliable method of exploration with a high degree of fiability, specificity and sensibility to study the local spread of malignant uterine diseases. The authors report their experience and also that present in the literature concerning the study of the uterus by MRI [fr

    2014-06-01

    Moving forward rapidly in the clinical research phase, uterus transplantation may be a future treatment option for women with uterine factor infertility, which accounts for three per cent of all infertility in women. This new method of treatment would allow women, who currently rely on gestational surrogacy or adoption, to gestate and birth their own genetic offspring. Since uterus transplantation carries significant risk when compared with surrogacy and adoption as well as when compared with other organ transplants, it requires greater justification because its goals are quality of life, not life-saving, in their scope. It is important to address questions regarding the physical, psychosocial and ethical risks and benefits of uterus transplantation for all three parties involved--the patient, the donor and the potential child--as well as discuss the regulatory implications as research on uterus transplantations moves forward.

  20. Loss of Progesterone Receptor-Mediated Actions Induce Preterm Cellular and Structural Remodeling of the Cervix and Premature Birth

    A decline in serum progesterone or antagonism of progesterone receptor function results in preterm labor and birth. Whether characteristics of premature remodeling of the cervix after antiprogestins or ovariectomy are similar to that at term was the focus of the present study. Groups of pregnant rats were treated with vehicle, a progesterone receptor antagonist (onapristone or mifepristone), or ovariectomized on day 17 postbreeding. As expected, controls given vehicle delivered at term while rats delivered preterm after progesterone receptor antagonist treatment or ovariectomy. Similar to the cervix before term, the preterm cervix of progesterone receptor antagonist-treated rats was characterized by reduced cell nuclei density, decreased collagen content and structure, as well as a greater presence of macrophages per unit area. Thus, loss of nuclear progesterone receptor-mediated actions promoted structural remodeling of the cervix, increased census of resident macrophages, and preterm birth much like that found in the cervix at term. In contrast to the progesterone receptor antagonist-induced advance in characteristics associated with remodeling, ovariectomy-induced loss of systemic progesterone did not affect hypertrophy, extracellular collagen, or macrophage numbers in the cervix. Thus, the structure and macrophage census in the cervix appear sufficient for premature ripening and birth to occur well before term. With progesterone receptors predominantly localized on cells other than macrophages, the findings suggest that interactions between cells may facilitate the loss of progesterone receptor-mediated actions as part of a final common mechanism that remodels the cervix in certain etiologies of preterm and with parturition at term.

    Full Text Available Bicornuate uterus is class IV and septate uterus is class Vin uterine anomaly classification.Bicornuate uterus is almost always treated by laparotomy and metroplasty. But the treatment of choice for septate uterus is hysteroscopic metroplasty. Bicornuate- septate uterus which is described in this paper is a new class of uterine anomaly(between class IV & V. The advantages of hysteroscopic metroplasty to laparotomy and metroplasty have been proven previously.It is important to know if the uterine anomaly is pure bicornuate or bicornuate-septate. In the latter case, we suggest the first line of operation should be hysteroscopic metroplasty.

    Full Text Available The reproductive form of Haemophilic infection caused by a microorganism Histophilus somni (Haemophilus somnus is in our conditions practically unknown and undiscovered disease of cow reproductive organs. The aim of this work was based on experimental work to provide a comprehensive view on the patho-histological and submicroscopic changes in the uterus of 60 cows, serological positive, crossbreeds Slovenske strakate x Holstein, aged 3.5 . 4.5 years, serological positive, which were up to 90 days after the parturition sterile. After the hormonal control of the oestrus cycle (PGF2ƒż-Oestrophan SPOFA the cows were inseminated and the non-gravid cows later killed. The reproductive organs of killed animals were pathologically . anatomically dissected with following histological and sub-microscopic study of uterus and cervix tissue. At the beginning of the experiment no clinical changes of the reproductive organs of group 1 animals with the titer of antibodies 1:25-100 were diagnosed and in group 3 with the titer 1:25. At an examination before killing were examined endometritis (EM of grade II. and vaginitis with vestibulitis in these groups. At the rest of animals appeared in every level of the titer of antibodies of EM II. and EM III. EM I. were not clinically diagnosed. Dissecting examination determined EM catarrhalis and cervicis catarrhalis in all groups. The histological examination pointed to EM catarrhalis chronica, EM interstitialis chronica, EM fibrousis and cervicis catarrhalis chronica. The leucocytes gained from a uterus lavage were in a comparison with stroma leucocytes mostly polynuclear (neutrophils and in smaller amount small forms of lymfocytes. At long-term sterility of cows, because of possible H. somnus infection, we regard as priority the serodiagnostics at which is taken into consideration any level of the titer of antibodies.

    Full Text Available A case of a uterine fibro-osteochondroma in a 61-year-old woman with postmenopausal bleeding was presented. Ultrasound revealed a calcified lesion in the posterior wall of the uterus and a hysterectomy was performed. Histopathologic examination showed a well-circumscribed triphasic tumor composed of peripheral lobules of mature hyaline cartilage and foci of trabecular bone with a core of loosely arranged fibroblast-like, spindle cells. This is the second reported case of fibro-osteochondroma, which has been described only in the uterus. Diagnosis requires thorough histopathologic examination to exclude metaplasia within a leiomyoma or uterine sarcoma. It is histologically benign and complete excision should be curative.

    This system is based on a principle of direct proportionality between the dimensions of the uterine cervix and the length of the vaginal sources. The system defines a reference isodose of fixed value encompassing a target volume of constant anatomic structures. The target volume always contains the same anatomic structures, independent of the tumor extent. The technique for doing the application is based upon certain practical principles: - the use of a cervical-vaginal plastic mould with a semi-rigid uterine tandem; - the use of 192 Ir wires; - the same uniform linear exposure rate for each source used in the application; - a single application for each patient; - the source in the uterus and the sources in the vagina are left in place for the same time. The maximum total dose is 60 Gy, calculated at the reference isodose of 4 Gy/day, assuming a linear nominal exposure rate of 1 mR x h -1 x m 2 x cm -1 . This corresponds to an effective dose rate which varies between 8 and 16 Gy/day, when the actual linear exposure rate of the 192 Ir wires is taken into account. The cervical dose, calculated at the level of the mucosa, is approximately twice the reference dose. It depends upon the size of the cervix, being 2.1 times the reference dose when the cervix is greater than 4 cm in diameter and 2.6 times when the cervix is less than 2.5 cm in diameter. The vaginal dose, calculated at the ''Cap Sassal point'', on the anterior part of the rectum, is always less than the reference dose [fr

    2012-01-01

    Purpose: Trans-abdominal ultrasonography (US) is capable of determining size, shape, thickness, and diameter of uterus, cervix and disease at cervix or parametria. To assess the potential value of US for image-guided cervical cancer brachytherapy, we compared US-findings relevant for brachytherapy to the corresponding findings obtained from MR imaging. Materials and methods: Twenty patients with biopsy proven cervical cancer undergoing definitive radiotherapy with/without concomitant Cisplatin chemotherapy and suitable for brachytherapy were invited to participate in this study. US and MR were performed in a similar reproducible patient positioning after intracavitary application. US mid-sagittal and axial image at the level of external cervical os was acquired. Reference points D1 to D9 and distances were identified with respect to central tandem and flange, to delineate cervix, central disease, and external surface of the uterus. Results: Thirty-two applications using CT/MR compatible applicators were evaluable. The D1 and D3 reference distances which represent anterior surface had a strong correlation with R = 0.92 and 0.94 (p < 0.01). The D2 and D4 reference distances in contrast, which represent the posterior surface had a moderate (D2) and a strong (D4) correlation with R = 0.63 and 0.82 (p < 0.01). Of all, D2 reference distance showed the least correlation of MR and US. The D5 reference distance representing the fundal thickness from tandem tip had a correlation of 0.98. The reference distances for D6, D7, D8, and D9 had a correlation of 0.94, 0.82, 0.96, and 0.93, respectively. Conclusions: Our study evaluating the use of US, suggests a reasonably strong correlation with MR in delineating uterus, cervix, and central disease for 3D conformal intracavitary brachytherapy planning.

    Full Text Available Uterus transplantation has been considered as an alternative management modality in the last few years for adoption or gestational surrogacy for women with absence of uterus due to congenital or acquired reasons. Surrogacy is legal in only a few countries because of ethical, social and legal issues. Up to date, a total of 11 uterus transplantation cases have been reported in which uteri were harvested from ten live donors and one donor with brain death. After unsuccessful attempt of first uterus transplantation, many studies have been conducted in animals and these experimental models enabled our knowledge to increase on this topic. First experimental studies were performed in rodents; later uterus transplantation was accomplished in sheep, pigs and rabbits. Recently, researches in non-human primates have led the experience regarding transplantation technique and success to improve. In this review, we reviewed the experimental animal researches in the area of uterus transplantation and recent experience in humans.

    Eighty-nine patients with previously untreated invasive carcinoma of the cervical stump were seen at Yale-New Haven Hospital from 1953 through 1977. This represented 9.4% of the carcinomas of the cervix seen during this time period. Eighty-five of the 89 patients (95.5%) had ''true'' cancers of the cervical stump diagnosed 2 years or more after subtotal hysterectomy, while 4 of the 89 patients (4.5%) had ''coincident'' cancers diagnosed within 2 years of the subtotal hysterectomy. All cervical cancers were staged by the F.I.G.O. classification. Patient characteristics, methods of management, failure sites and survival of patients with carcinoma of the cervical stump were compared to those patients with carcinoma in the intact uterus. Patients with cervical stump cancers were treated in a similar manner to those with carcinomas of the intact uterus, using a combination of external beam irradiation and intracavitary radium. The stump cancer patients had a similar stage distribution to the patients with cancers of the intact uterus but, on the average, they were older and received less irradiation. The patterns of failure were similar on a stage for stage basis, but the survival and disease-free survival for stump cancer patients were superior to those of the patients with carcinoma of the intact uterus

    INTRODUCTION. In the medical literature is quoted the nulliparity, the existence of previous operations and the uterus size as exclusion factors to choice the hysterectomy technique. The aim of present research was to determine the effectiveness and feasibility of vaginal hysterectomy by Heaney's technique, carried out in patients without uterus prolapse even in presence of the above mentioned factors. METHODS. A multivariate, descriptive and observational study was conducted in a sample including 1 000 patients operated on in the General Surgery service of the 'Martin Chang Puga' University Hospital in Nuevitas municipality (Camaguey province, between May, 1994 and December, 2006. A database was designed in Excel transferred to SPSS professional statistical package to carry out univaried, bivaried and multivariate analyses, which finally were represented in frequency and percentages tables. A significance of p= 0.05 was used. RESULTS. The 6 % of patients were nulliparous and the 23,5 % had previous surgeries of pelvis. A 82,6 % of patients had uteri with no more than an approximate value of 12 weeks of pregnancy and the uterine fibroma was the leading cause (88,5 %) of intervention. Only a 4,1 % of patients need blood transfusion. The perioperative and postoperative complications accounted for the 1,7 % and the 19,3 %, respectively. The 97,2 % of patients stayed less than 48 hours in the hospital and the 99,4 % go back to normal life. CONCLUSIONS. The nulliparity, the uterus size and the previous operations were not considered like isolated and excluding factors for the vaginal route. However, the type of hysterectomy will depends of the decision of the attending physician and the patient, according the costs and benefits involved in each case. (author)

    Five patient with a hysterosalpingographic diagnosis of unicornuate uterus underwent resonance imaging (MRI) and subsequently laparoscopy/laparotomy to evaluate the ability of MRI to identify the various subclasses of this malformation. The method was demonstrated to be valid, since in all 5 cases (one subclass A1b, two subclass B) were correctly diagnosed. Compared with laparoscopy, MRI is less expensive, less invasive, and can be performed in women in whom laparoscopic examination is risky. However, unlike laparoscopy, MRI can not detect the presence of minimal and mild endometriosis and does not allow assessment of the tubal conditions. (au).

    Full Text Available OBJETIVO: estudar as alterações histoquímicas relacionadas às glicosaminoglicanas da cérvice uterina da rata albina, após ministração local de hialuronidase no final da prenhez. MÉTODOS: dez ratas com teste de prenhez positivo foram distribuídas aleatoriamente em dois grupos, numericamente iguais. O Grupo Controle (Gc foi constituído pelas ratas que receberam 1 mL de água destilada, dose única, no 18º dia da prenhez, sob anestesia, ministrado na cérvice uterina. O Grupo Experimental (Gex constou de ratas que receberam, sob as mesmas condições do Gc, 0,02 mL de hialuronidase, diluído em 0,98 mL de água destilada (total de 1 mL. No 20º dia de prenhez, as ratas foram novamente anestesiadas e submetidas à dissecção, preparando-se a cérvice uterina para estudo histoquímico com coloração de alcian blue e seus bloqueios (pH=0,5, pH=2,5, metilação e saponificação. RESULTADOS: verificou-se na lâmina própria no Gc, reação fortemente positiva (+3 e, no Gex, reação negativa, na coloração de alcian blue no pH=0,5. Em pH=2,5 a coloração também se apresentou fortemente positiva (+4 no Gc e fracamente positiva (+1 no Gex. Após metilação, tanto o Gc quanto o Gex mostraram reação negativa após coloração de alcian blue no pH=2,5. Com a reação de metilação seguida de saponificação e na digestão enzimática em lâmina, a coloração da lâmina própria se mostrou negativa em ambos os grupos. CONCLUSÕES: há uma nítida predominância de glicosaminoglicanas sulfatadas no Gc em relação ao Gex e uma tênue quantidade de glicosaminoglicanas carboxiladas identificadas no Gex. As modificações evidenciadas na matriz extracelular sugerem que a hialuronidase injetada localmente na cérvix uterina promoveu alterações bioquímicas compatíveis com maturação cervical.PURPOSE: to study the histochemical changes related to the uterine cervix glycosaminoglycan of the albino female rat, after local ministration of

    This study reports on 5 years experience of the treatment of carcinoma of the cervix and poor-risk carcinoma of the body of the uterus using a combination of external beam radiotherapy and high-dose-rate intracavitary 60Co-brachytherapy using the Cathetron since 1979 at the Middlesex Hospital, London. Despite a reduction in external beam dose of 20% since 1979, survival rates for both diseases remain unchanged and also compare favourably with those of other centres; they are 70.02% for carcinoma of the cervix of all stages except Ia, and 81.17% for 'poor-risk' carcinoma of body of uterus of all stages. The complication rates were acceptable. Analysis of the results of treatment by stage of disease in those patients with carcinoma of the cervix revealed that, except for Stage I cases, the results were comparable with those reported in the literature. The reason for the poor results in Stage I was found to be due to the high proportion of patients of 35 years of age and under with Stage I disease who fared significantly worse than older patients.

  1. Pain management in cancer cervix

    Full Text Available Cancer of the cervix uteri is a common cause of pain among women. On the physical realm, the cancer may cause somatic [soft tissue and bone], visceral and neuropathic pain [lumbosacral plexopathy]. Radiotherapy and chemotherapy may cause neuropathy too. Psychological, social and cultural factors modify the pain. Evaluation of the individual type of pain and a patient-centred approach are fundamental requirements for rational management. Disease modifying treatment like radiotherapy and chemotherapy must be considered when applicable. Pain control is usually achieved by the use of WHO three-step ladder, remembering that possible association of renal dysfunction would necessitate caution in the use of NSAIDs and opioids. Side effects must be anticipated, prevented when possible, and aggressively treated; nausea and vomiting may already be present, and constipation can worsen pain when there is a pelvic mass. Pain emergencies can be treated by quick titration with intravenous morphine bolus doses. Neuropathic pain may warrant the use of usual adjuvants, with particular reference to cortico-steroids and the NMDA antagonist, ketamine. In intractable pain, many neurolytic procedures are tried, but a solid evidence base to justify their use is lacking. Continuous epidural analgesia with local anaesthetic and opioid may be needed when drug therapy fails, and desperate situations may warrant interventions such as neurolysis. Such physical measures for pain relief must be combined with psychosocial support and adequate explanations to the patient and the family.

    Survival data, prognostic factors, and patterns of failure were retrospectively analyzed for a total of 76 patients with adenocarcinoma of the uterine cervix treated between January 1981 and December 1987, which represents 4.1% of all primary cervical carcinomas treated, at Department of Radiation Oncology, Yensei Cancer Center, Yonsei University College of Medicine. The mean age of the patients was 49years(range, 27-79years) and the peak incidence was in the group 50 to 59years of age. More half of the patients were postmenopausal (46/76=60.5%). Most patients(76%)had abnormal vaginal bleeding either alone or in combination with other symptoms. The proportion of stage Iib was 43.4%. There were 4 major histologic subtypes: pure adenocarcinoma(48/76=63.2%), adenosquamous carcinoma(20/76=26.3%), papillary (5/76=6.6%) and clear cell carcinoma(3/76=3.9%). Of the many clinicopathologic variables evaluated for prognosis, the most significant prognostic factors were stage of disease and the size of tumor. The overall 5-year survival rate was 68%, and the 5-year survival rates for stage Ib, II and III were 90%, 66% and 54%, respectively. Control of pelvic tumors was achieved in 938%, 90.2% and 50.0% of cases of stage Ib, II and III disease, respectively.

    To demonstrate an approach to the hysteroscopic management of a stenotic cervix. Step-by-step explanation of the techniques using video and animation (educational video). Academic tertiary level referral center. Patients with cervical stenosis, inclusive of both reproductive age and postmenopausal women. Gynecologists require intrauterine access for many procedures, but a stenotic cervix can obstruct surgery. Blind dilation of a stenotic cervix can lead to a cervical laceration or uterine perforation, with concomitant complications. The hysteroscopic management of a stenotic cervix includes optimizing the surgical environment, performing vaginoscopy and "no-touch" hysteroscopy, and revision of the cervical canal. Revision can be performed using microscissors, micrograspers, or a cutting loop electrode. Partial cervical canal excision to aid in hysteroscopy access should be reserved in women who are not interested in future pregnancy or those who are postmenopausal. Outpatient hysteroscopy uses smaller instruments and shows operative success with patient satisfaction. Although these techniques are demonstrated in an outpatient hysteroscopy setting, they can be adapted for use in an operating theater. The individual steps and approach are emphasized. Intrauterine access can be achieved with various techniques. The "see-and-treat" approach demonstrated in this video can allow access into the uterine cavity despite a stenotic cervix.

    Accurate staging as well as diagnosis of cervix carcinoma is of paramount importance in planning treatment. Cervical smear cytologic studies have increased the detection rate of cervix carcinoma, but current radiologic techniques are limited in staging cervix carcinoma and precise visualization of lymphnodal metastasis. The CT scan can display the precise transaxial anatomical structures, permitting us not only to know the tumor size, shape and its extent but also lymphnodal enlargement in the pelvic cavity and around the abdominal aorta and secondary changes of the kidney. The authors have tested the usefulness of CT in staging cervix carcinoma and detecting lymphatic involvement by analysis of 24 cases diagnosed by CT and confirmed histologically at St. Mary's hospital during the period from October 1982 to May 1984. The conclusions are as follows: 1. The accuracy of CT in staging of cervix carcinoma was 79%. 2. The accuracy of CT diagnosis of lymphatic involvement was 87.5%, sensitivity was 85.7%, and specificity was 88.2%

    The birth of a child after uterus transplant from a living donor in Sweden in October, 2013 has spurred reproductive and transplant physicians in Europe and North America to investigate whether uterus transplants, from living or cadaveric donors, will be a safe and effective therapy for women with uterine insufficiency. While progress with uterus transplant depends on medical factors, there are also important ethical and legal concerns. Uterus transplant is essential for women without access to surrogacy. It may also be sought by infertile women who dislike surrogacy. This article examines medical, ethical, legal, and policy issues that arise with womb transplant, including the role of surrogacy policies that make them necessary. The conclusion is that there is a clear ethical path for either surrogacy or uterus transplant to be used by women with uterine insufficiency. PMID:27774233

    A vulvovaginal discharge following parturition in a bitch is often a cause of concern to owners and clinicians, especially if whelping was complicated in any way. Ultrasonography could potentially distinguish between normal and abnormal postpartum uterine states because the uterine wall and luminal contents can be imaged in detail. Five normal bitches were examined to determine the normal ultrasonographic appearance of the postpartum uterus and the sensitivity of ultrasonography in detecting the involuting uterus, comparing this sensitivity with that of radiography. Ultrasonography was done at 1, 4, 8, 12, 18 and 24 days postpartum, radiography at 1, 4, 8, 12 and 18 days postpartum. By 12 days postpartum, the uterus could not be seen on radiographs, while at 24 days postpartum the uterus was still sonographically identifiable. The ultrasonographic characteristics of the involuting uterus are described

    The clinical symptoms of pathologies of the uterus and ovaries are relatively unspecific. Their presentation includes absence of symptoms, abdominal pain and acute abdomen - but also developmental alterations during puberty and problems with menstruation and conception. Ultrasound can reliably diagnose most of these diseases. MRI is being a second line of diagnostics especially in cases of malformation and possible tumors. It is decisive for a valid interpretation of results to be aware of age-dependent normal findings and to have a working knowledge of embryologic processes, especially to understand how deformities take shape. This article is presenting normal findings and many pathologies of the female inner genital in childhood and puberty. By using exemplary images we will cover their differential diagnoses, pitfalls and typical presentations.

    In a 58-year-old postmenopausal woman blood flow and blood pool images of bone scintigraphy showed a focus of increased activity in the right pelvic region. Computed tomography and ultrasound exhibited no abnormalities in the abdomen; especially the uterus and ovaries were normal. Careful anamnestic evaluation revealed that the patient received a long-term peroral estrogen/gestagen replacement therapy for the prevention of osteoporosis, but did not have menstruation-like bleedings for the last twelve months of therapy. At time of admission, the patient was on day 25 of hormone replacement therapy, and the uterus wash, therefore, in a premenstrual stage. Hence, despite cessation of bleedings in postmenopausal women, one should think of hormone replacement therapy as an explanation for vascular pelvic tumors seen by the first two phases of bone scintigraphy, before further diagnostic steps are undertaken.

    Epithelioid sarcoma is a rare malignant mesenchymal neoplasm (less than 1% of all sarcomas) with epithelioid morphology. Among the 2 subtypes, proximal represents only one-third of cases and commonly involves deep tissues of pelvic region, including the perineum, genital area, and groin, and occurs more frequently in older patients who present a more aggressive course. In the female genital tract, proximal-type epithelioid sarcoma (PES) mainly affects the vulva and is extremely uncommon in the uterus. To our knowledge, only a few cases of PES involving the cervix and uterine body have been previously reported in the literature. We report a 23-year-old woman who presented with abnormal vaginal bleeding. She was found to have a cervical mass, which was resected and diagnosed as a hemangioendothelioma. However, 2 months later, the mass recurred and the histopathological analysis at our institution demonstrated a PES confined to the uterine cervix. It is important to include this neoplasm in the differential diagnosis of epithelioid tumors that can involve the female genital tract because it has a significant impact on prognosis and treatment.

    The results of radiotherapy of 374 cases of cancer of the cervix uteri, 163 cases of carcinoma of the endometrium, 24 cases of cancer of the cervival stump and 16 cases of sarkoma of the uterus carried out during the years 1967 to 1972 are shown. The absolute 5-year cure rates in our case material were 60,4 % for cancer of the cervix uteri and 73,0 % for carcinoma of the endometrium. In comparison with the treatment results reported in the years 1962 to 1966 an increase in radiotherapeutical efficiency was found, amounting to 8,8 % in case of cancer of the cervix uteri and 13,2 % in case of carcinoma of the endometrium. We also compared and analysed the different cure rates in case of primary irradiation (52,6 % resp. 55,8 %) as opposed to postoperative radiotherapy '76,9 % resp. 81,1 % cure rates). The frequency of radiation injuries and the rate of recurrence or metastases, as well as the incidence of concomitant diseases and complications have been reported and compared with those of other clinics.

    Congenital uterine anomalies like bicornis or bicornuate uterus are relatively rare in sub-Saharan Africa. They are associated with an increased rate of spontaneous abortion, preterm delivery, and infertility. The occurrence of bicornis bicollis uterus with unilateral cervical atresia is exceptional and its management is controversial. We hereby report a rare cause of chronic pelvic pain in a Cameroonian teenager due to unilateral obstructive hematometra and hematosalpinx in the non-communicating horn of a bicornis bicollis uterus. A 13-year-old premenarchal non-virgin female presented with chronic and severe cyclical crampy pelvic pain. On clinical examination, she had a perforated hymen, a single vagina, and one uterine cervix. A two-dimensional pelvic ultrasonography revealed hematometra but missed out the underlying anomaly. Failure to drain the hematometra by serial cervical dilatations prompted an exploratory laparotomy which revealed: bicornis bicollis uterus with a right rudimentary uterine horn communicating with the vagina and a left non-communicating uterine horn distended by hematometra due to a homolateral cervical atresia. She underwent utero-vaginal canalization and a left hemi-hysterotomy with drainage of the hematometra. The postoperative period was uneventful. Regular cyclic menses occurred thereafter beginning at the first postoperative month. She had complete resolution of symptoms without recurrence after six months. Due to the risk of compromised fertility from bicornis uterus and the diagnostic challenges akin to resource-limited settings, we highlight the need for a high index of suspicion by healthcare providers when faced with chronic pelvic pain in premenarchal adolescents.

    Full Text Available Smoking is associated with higher infertility risk. The aim of this study was to evaluate protective effects of melatonin on the uterus and oviduct in mice exposed to nicotine. Adult female mice (n=32 were divided into four groups. Group A: control animals received normal saline, Group B: injected with nicotine 40 μg/kg, Group C: injected with melatonin 10 μg, Group D: injected with nicotine 40 μg/kg and melatonin 10 μg. All animals were treated over 15 days intraperitoneally. On the 16th day, animals in the estrus phase were dissected and their uterus and oviducts were removed. Immunohistochemistry was recruited for studying apoptosis and for detection of estrogen receptor (ER alpha in luminal epithelium of the uterus and oviduct. Enzyme-linked immunosorbent assay was used for serum estradiol level determination. Nicotine in group B decreased estradiol level and ERalpha numbers both in the uterus and oviduct (p<0.05. Co-administration of melatonin-nicotine in Group D ameliorated the histology of the uterus and oviduct, increased ERalpha numbers and reduced apoptosis in the uterus and oviduct compared with the nicotine Group B (p<0.05. This study indicates that nicotine impairs the histology of the uterus and oviduct and co-administration of melatonin-nicotine ameliorates these findings, partly through alteration in ERalpha numbers and reduction of apoptosis

    Full Text Available This paper works at segmentation of lesion observed in cervical cancer, which is the second most common cancer among women worldwide. The purpose of segmentation is to determine the location for a biopsy to be taken for diagnosis. Cervix cancer is a disease in which cancer cells are found in the tissues of the cervix. The acetowhite region is a major indicator of abnormality in the cervix image. This project addresses the problem of segmenting uterine cervix image into different regions. We analyze two algorithms namely Watershed, K-means clustering algorithm, Expectation Maximization (EM Image Segmentation algorithm. These segmentations methods are carried over for the colposcopic uterine cervix image.

    Purpose: Accurate target definition is vitally important for definitive treatment of cervix cancer with intensity-modulated radiotherapy (IMRT), yet a definition of clinical target volume (CTV) remains variable within the literature. The aim of this study was to develop a consensus CTV definition in preparation for a Phase 2 clinical trial being planned by the Radiation Therapy Oncology Group. Methods and Materials: A guidelines consensus working group meeting was convened in June 2008 for the purposes of developing target definition guidelines for IMRT for the intact cervix. A draft document of recommendations for CTV definition was created and used to aid in contouring a clinical case. The clinical case was then analyzed for consistency and clarity of target delineation using an expectation maximization algorithm for simultaneous truth and performance level estimation (STAPLE), with kappa statistics as a measure of agreement between participants. Results: Nineteen experts in gynecological radiation oncology generated contours on axial magnetic resonance images of the pelvis. Substantial STAPLE agreement sensitivity and specificity values were seen for gross tumor volume (GTV) delineation (0.84 and 0.96, respectively) with a kappa statistic of 0.68 (p < 0.0001). Agreement for delineation of cervix, uterus, vagina, and parametria was moderate. Conclusions: This report provides guidelines for CTV definition in the definitive cervix cancer setting for the purposes of IMRT, building on previously published guidelines for IMRT in the postoperative setting.

    The distribution and effects of the two neuropeptides, vasoactive intestinal polypeptide (VIP) and peptide histidine isoleucine amide (PHI), on vascular and nonvascular smooth muscle in the urogenital tract of nonpregnant rabbit female, were investigated. Immunoreactive VIP and PHI were present in all regions except the ovary with the highest concentration in the uterin cervix. By using in vitro tension recordings of myometrial specimens, it was demonstrated that both peptides displayed a dose-dependent inhibition of the mechanical activity. The dose-response curves of VIP and PHI were superimposable with and ID 50 of 3 x 10 -8 mol/l, and their combined effect was additive. In addition, the influence of the two peptides on myometrial blood flow (MBF) was investigated by the xenon-133 washout technique. Both peptides were found to increase MBF with the same potency and efficacy. Their combined effect was additive. In conclusion VIP and PHI are present in the rabbit urogenital tract, and the two peptides are equipotent inhibitors of mechanical nonvascular and vascular smooth muscle activity in the uterus

    Full Text Available Mullerian adenosarcoma following tamoxifen therapy is a rare condition. Our aim was to report the youngest patient in the literature with uterine mullerian adenosarcoma who was undergoing tamoxifen therapy for breast cancer. A premenopausal woman aged 38 years who was undergoing tamoxifen therapy for breast cancer, was admitted with symptoms of lower abdominal pain and irregular vaginal bleeding and malodorous vaginal discharge that had continued for at least 6 months. A pelvic examination revealed a large and malodorous polypoid mass protruding through the cervix and an enlarged uterus. A biopsy from the protruding polypoid mass was reported as a large area of necrosis with neoplastic mesenchymal cells. The patient underwent a total abdominal hysterectomy, bilateral salpingo-oopherectomy, pelvic-paraaortic lymph node dissection, and omentectomie. The histologic diagnosis was Mullerian adenosarcoma. As a result, she was discharged to the oncology department. The woman is alive and her chemoradiotherapy treatment is ongoing. The role of tamoxifen therapy in the development of endometrial neoplasms remains unclear, but all cases of endometrial thickening and vaginal bleeding must be investigated for Mullerian adenosarcoma in tamoxifen users.

    Full Text Available In November 2013, a woman with Herlyn-Werner-Wunderlich (HWW syndrome was diagnosed with a locally advanced left cervical adenocarcinoma. The patient’s malformation consisted of two uteri with two cervixes, a obstructed vagina, and a left renal agenesis. Classification FIGO: stage IIIa because of infiltration of the inferior third of the vagina wall. Locoregional management comprised an infrarenal lateral aortic lymphadenectomy followed by concomitant radio-chemotherapy to the pelvic (inguinal, pelvic, and infrarenal para aortic nodes volumes. A total of 50.4 Gy were delivered (1.8 Gy/fraction/day to the node (inguinal, pelvic, and aortic infrarenal and pelvic volume; a concomitant boost to the primary cervical tumor and macroscopic nodes to 59.92 Gy (2.14 Gy/fraction/day was performed. 20 Gy were delivered with intracavitary brachytherapy boost with mold technique and a pulsed-dose-rate technique due to the rarity of this uterine malformation. After 30 months of follow-up, there was no evidence of locoregional or distant recurrence.

    To define the appearence of the uterus and the uterine cavity, as revealed by the ultrasound in normal women following a vaginal delivery. This prospective, longitudinal study took place at the Prince Hashem and the Prince Ali Military Hospitals, Amman Jordan from December 2002 to March 2003. Fifty four women were scanned on postpartum days 1, 7, 14, 28 and 56. Ultrasound operation was performed transabdominally for all women. The involution process of the uterus was assessed by measuring the anteroposterior diameter and uterine cavity. The appearence of the uterine cavity content was documented. Factors related to the involution process: parity, breast-feeding, smoking and infant's birth weight were also evaluated. The maximum anteroposterior diameter of the uterus diminished substantially and progressively from 93mm on day one postpartum to 38.5 mm on day 56. The maximum anteroposterior diameter of the uterine cavity diminished from15.2 mm on day one to 4.0 mm on day 56. The position of the uterus, its shape and the appearence of its cavity during the normal puerperium was observed. The uterus was most often retroverted and empty in the early puerperium. Fluid and debris in the whole cavity were seen in mid puerperium, the cavity was empty and appeared as a thin white line. No correlation was found between the involution of the uterus and parity, breast-feeding and infant's birth weight. Transabdominal sonography is suitable for examination of the uterus during the early puerperium period. The uterine body and position, as well as the cavity, are easy to examine by ultrasound. Accumulation of fluid and debris in the uterine cavity is a common and insignificant finding of the invluting uterus. (author)

    Hysteroscopy is an operation in which the gynaecologist examines the uterine cavity using a small telescopic instrument (hysteroscope) inserted via the vagina and the cervix. Almost 50% of hysteroscopic complications are related to difficulty with cervical entry. Potential complications include cervical tears, creation of a false passage, perforation, bleeding, or simply difficulty in entering the internal os (between the cervix and the uterus) with the hysteroscope. These complications may possibly be reduced with adequate preparation of the cervix (cervical ripening) prior to hysteroscopy. Cervical ripening agents include oral or vaginal prostaglandin, which can be synthetic (e.g misoprostol) or natural (e.g. dinoprostone) and vaginal osmotic dilators, which can be naturally occurring (e.g. laminaria) or synthetic. To determine whether preoperative cervical preparation facilitates cervical dilatation and reduces the complications of operative hysteroscopy in women undergoing the procedure for any condition. In August 2014 we searched sources including the Menstrual Disorders and Subfertility Group (MDSG) Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, PsycINFO, CINAHL, ClinicalTrials.gov and reference lists of relevant articles. We searched for published and unpublished studies in any language. Two review authors independently selected randomised controlled trials (RCTs) of cervical ripening agents used before operative hysteroscopy in pre- and postmenopausal women. Cervical ripening agents could be compared to each other, placebo or no treatment. Data extraction and quality assessment were conducted independently by two review authors. The primary review outcomes were effectiveness of cervical dilatation (defined as the proportion of women requiring mechanical cervical dilatation) and intraoperative complications. Secondary outcomes were mean time required to dilate the cervix, preoperative pain, cervical width

    Full Text Available BACKGROUND Cancer cervix is the second most commonly-diagnosed cancer among women worldwide. The aim of the study is to evaluate the histopathological diagnosis of cancer cervix and to determine the incidence of the various types of cancerous lesions. MATERIALS AND METHODS It was a prospective study in the Department of Pathology, Andhra Medical College/King George Hospital over a period of one year. 152 women with carcinoma cervix were included in the study. RESULTS 152 cases of carcinoma of cervix were in the age group of 28-76 years. The mean age of the patients with carcinoma cervix is 52.97. Histologically, Large Cell Non-Keratinising Squamous Cell Carcinoma (LCNKSCC constituted the majority of carcinoma cervix cases, i.e. 134 cases (88.15%. 3 (1.97% cases of adenocarcinoma of cervix were diagnosed in the present study. Majority of cases of carcinoma cervix were in stage III, i.e. 64 cases (64%, followed by stage II in 24 cases (24% and stage IB in 8 cases (8%. CONCLUSION Large Cell Non-Keratinising Squamous Cell Carcinoma (LCNKSCC is the most common histological type of carcinoma cervix. A relatively large proportion of patients presented in stages IIIA and IIIB. There is a need to reinforce the early detection of carcinoma cervix and its precursor lesions, especially in developing countries.

    Radiotherapy is the most efficient method of treatment of the carcinoma of the cervix. It is usually accepted also that the incidence of some sequels is justifiable as soon as it be kept in the lowest level possible. Trying to find out if this has correlation with the incidence of hypogastrium subcutaneous fibrosis in the cervix carcinoma treatment, 96 patients treated at Instituto de Radioterapia Osvaldo Cruz were analysed. The incidence of fibrosis was related to treatment techniques, tumor dose and TDF factor. The results indicated that TDF factor is the only one that can be directly related to the incidence of this sequel. The critical value for TDF factor was fixed at 110, and any increase on it elevates the fibrosis incidence by a factor of 5. Finally it is recommended that the TDF calculation should be utilized as the main factor in the selection of the several parameters involved in this kind of treatment. (F.R.) [pt

    A selected group of 136 patients with Stage I squamous cell carcinoma of the cervix was treated in six naval hospitals during the period 1957--1965 using a three-stage combined radiation therapy and surgery protocol. Treatment consisted of two radium applications to the cervix, followed in 6 weeks by extraperitoneal lymphadenectomy. If the lymph nodes were tumor-negative, simple hysterectomy in 3 to 6 months completed the protocol. If the nodes were tumor-positive, a course of external pelvic irradiation was given with midline shielding. The incidence of positive nodes was 9.6 percent. Actuarial survival for all patients was 89.4 percent, comparable to the rate obtained by radical surgery or radiation alone. Postoperative and postradiation complications were minimal, with no urinary or bowel fistulas. There was no operative mortality

    In the mammalian cell nucleus, splicing factors are distributed in nuclear domains known as speckles or splicing factor compartments (SFCs). In cultured cells, these domains are dynamic and reflect transcriptional and splicing activities. We used immunofluorescence and confocal microscopy to monitor whether splicing factors in differentiated cells display similar features. Speckled patterns are observed in rat hepatocytes, beta-cells, bronchial and intestine epithelia and also in three cell types of the uterus. Moreover, the number, distribution and sizes of the speckles vary among them. In addition, we studied variations in the circular form (shape) of speckles in uterine cells that are transcriptionally modified by a hormone action. During proestrus of the estral cycle, speckles are irregular in shape while in diestrus I they are circular. Experimentally, in castrated rats luminal epithelial cells show a pattern where speckles are dramatically rounded, but they recover their irregular shape rapidly after an injection of estradiol. The same results were observed in muscle and gland epithelial cells of the uterus. We concluded that different speckled patterns are present in various cells types in differentiated tissues and that these patterns change in the uterus depending upon the presence or absence of hormones such as estradiol.

    Purpose : This study was done to analyze survivals, patterns of failure, and complications of early uterine cervix cancer after curative radiotherapy. Methods and Materials : Eighty patients with uterine cervix cancer FIGO Stage IB (48 cases) and Stage IIA (32 cases) treated with radiotherapy were analyzed retrospectively. Patients were treated from November 1985 to May 1993, and minimum follow up period was 24 months. and 6 cases were lost to follow up. All of them were treated with external radiotherapy and different fractions of high dose rate intracavitary radiotherapy. Survival rates, failure patterns, complication rates and degrees of severity were analyzed according to several factors. Results : Overall 5 year survival rate and relapse free survival rate were 72.3%, and 72.8% respectively. Prognostic factors were stage, size, pathology, RT response and there was no significant survival difference among the reasons of radiotherapy choice. There were 19 cases of treatment failure, another 3 cases were not tumor related death, and most of treatment related failure occurred within 24 months. Late complication rate of bladder and rectum were 8.8%, 15% respectively, frequency and severity of complication were correlated with ICR fractionation dose and total dose. Conclusion : These results showed that survival rates of early stage radiation treated cervix cancer patients were comparable to surgical series, but more aggressive treatment methods needed for stage IIA poor prognostic patients, To decrease late complication, choice of proper ICR dose and meticulous vaginal packing is needed

    Full Text Available Case series summary A queen, tom and four 1-year-old female offspring presented for routine neuter. Two of the littermates (cats 1 and 2 were diagnosed with a uterine abnormality during surgery. The left uterine horn of both cats appeared as a thin, solid, cord-like structure, whereas the right uterine horn of both cats appeared to have intermittent bulges consistent with pregnancy. The two other littermates, queen and tom were reproductively normal. The uteruses of the affected cats were nearly identical with a gross and histopathologic diagnosis of uterus unicornis with concurrent pregnancy. Ovaries were present, bilaterally. An oviduct was present only on the single normally developed and pregnant uterine horn in both cats. At a postoperative follow-up evaluation, abdominal ultrasound was performed on the two cats with uterine abnormalities. Cat 1 was ultrasonographically within normal limits. Cat 2 was diagnosed with ipsilateral renal agenesis on the same side as the absent uterine horn. Relevance and novel information The complexity of uterus unicornis and renal aplasia is demonstrated by this unique presentation of five related cats for ovariohysterectomy. This report raises questions regarding the genetic, environmental, hormonal or other underlying causes of this anatomic abnormality in cats that may spur additional research. This is the first publication describing uterus unicornis in gravid feline littermates, with one of the cats having ipsilateral renal agenesis. This is also the first publication to describe oviduct agenesis on the affected uterine horn in feline uterus unicornis.

    2017-07-01

    The recent successful births following live donor uterus transplantation are proof-of-concept that absolute uterine factor infertility is a treatable condition which affects several hundred thousand infertile women world-wide due to a dysfunctional uterus. This strategy also provides an alternative to gestational surrogate motherhood which is not practiced in most countries due to ethical, religious or legal reasons. The live donor surgery involved in uterus transplantation takes more than 10 h and is then followed by years of immunosuppressive medication to prevent uterine rejection. Immunosuppression is associated with significant adverse side effects, including nephrotoxicity, increased risk of serious infections, and diabetes. Thus, the development of alternative approaches to treat absolute uterine factor infertility would be desirable. This review discusses tissue engineering principles in general, but also details strategies on how to create a bioengineered uterus that could be used for transplantation, without risky donor surgery and any need for immunosuppression. We discuss scaffolds derived from decellularized organs/tissues which may be recellularized using various types of autologous somatic/stem cells, in particular for uterine tissue engineering. It further highlights the hurdles that lay ahead in developing an alternative to an allogeneic source for uterus transplantation.

    Full Text Available Background. Mullerian duct anomalies (MDAs are congenital defects of the female genital system that arise from abnormal embryological development of the Mullerian ducts. A didelphys uterus, also known as a “double uterus,” is one of the least common amongst MDAs. This report discusses a case of didelphys uterus that successfully conceived, carried her pregnancy to term, and delivered vaginally without any significant complications. Case. Patient is a 29-year-old G2P0010 from Bangladesh, initially came a year prior in her first pregnancy, with spontaneous abortion (SAB. Pelvic Sonogram at that time showed a diagnosis of bicornuate versus didelphys uterus. There were no renal anomalies on subsequent abdominal CT scan. Patient presented with the second pregnancy and had uncomplicated prenatal care and did not have signs of preterm labor; fetus showed appropriate growth and the pregnancy was carried in the left uterus. Patient presented at 38 4/7 wks with Premature Rupture of Membrane and underwent induction of labor with Cytotec. Antibiotics were started for chorioamnionitis. Patient had a vaginal delivery with left mediolateral episiotomy and complete tear of vaginal septum. Third stage of labor was complicated with retained placenta, which was removed manually in the operating room with total EBL of 600 cc.

    Cervix uteri and Corpus uteri were amongst the first sites to be classified by the TNM system. The ''League of Nations'' Stages for carcinoma of the cervix have been used with minor modifications for nearly fifty years and because these are accepted by the Federation Internationale de Gynecologie et d'Obstetrique (FIGO), the TNM categories have been defined to correspond to the FIGO stages. Some amendments have been made in collaboration with FIGO and the classifications now published will remain unchanged until at least 1986

    2007-06-01

    Full Text Available Abstract Cotyledonoid dissecting leiomyoma of the uterus is a recently described rare variant of benign uterine leiomyoma. We report a case of cotyledonoid dissecting leiomyoma in a 52 year old woman who presented with menorrhagia and abdominal pain. An ultrasound scan showed a bulky uterus and a cystic heterogenous mass near the left ovary. At hysterectomy, the left broad ligament mass was removed. This was continuous with an ill-defined nodular area in the myometrial fundus. Microscopy revealed a benign smooth muscle proliferation in the myometrium that extended beyond the uterus and into the broad ligament. The lesion appeared to be dissecting the myometrial fibres and showed areas of oedema, hyalinisation and perinodular hydropic change. Cellular atypia, mitoses and coagulative necrosis were absent. The patient is alive and well 18 months after surgery. It is important to recognize this benign and unusual appearing variant of leiomyoma in order to prevent inappropriate treatment.

    Background. While fungal infections of the bovine uterus are well-known diseases in pregnant cattle, very limited knowledge exists on the presence and significance of fungi in the uterus of non-pregnant cows. Presence of fungi in the uterine lumen of postpartum (pp) cows has been reported......, but little attention has been paid to this as most studies of the bovine pp uterus have focused on bacteria. Case presentation. Microscopy of uterine lavage cytology slides of three cows from one herd revealed the presence of numerous yeast-like organisms, which were located either free in the fluid...... pregnant and delivered a normal calf at term, while the two others were not bred. Conclusions. Candida kefyr is commonly isolated from milk of cows with mastitis, but has not been reported in association with other diseases of cattle. The infection was present as a monoculture in all three cows...

    331 patients of stage IIb uterine cervix cancer treated by radiation alone at Kosin Medical Center between June 1980 and Dec. 1985 were analysed to determine parameters of radiotherapy associated to disease states. Survival rate was highest among the reported (82.8% for crude and 82.4% for disease free survival). Pelvic control rate in 6 weeks after the end of radiotherapy was 93.6% in the patients treated with ICR following total pelvic radiation and 71.6% with small field additional external irradiation. 5 year survival rate in those who achieved pelvic control was 98. 9% and 12.9% in those who had pelvic failure and/or metastasis after radiation. The survival rate figured maximal 88.5% with dosage of 7500-8500 cGy to point A with acceptable incidence of complications (4.9%) but without increasing survival above it and minimal 74.1% with dosage of less than 6500 cGy. The treatment failure was counted 18.7% (62 of 331 patients): Local failure 72. 6% ( 45 of 62 patients), locoregional failure 3.2% (2 of 62 patients) and distant failure 24% (15 of 62 patients). Late complications were found In 50 patients (15.1%) and 42% of them was rectal bleeding and stenosis. The dose of 8500 cGy to point A was found to be critical for complication and 70% of complications occurred above it and was more serious one such as fistula. Rectal complications were developed above rectal dose 6500 cGy and bladder complication above bladder dose 7500 cGy. Major cause of death was cachexia due to locoregional failure (73.7% of death), next was due to metastasis to lung, liver and bone, and only 3 patients died of complication of intestinal perforations and obstruction. In conclusion higher external radiation dose for a bulky uterine cervix and barrel shaped uterus was essential for local control.

    Purpose: The aim of this study was to investigate the potential dose reduction in the uterus as a result of lead apron protection during thoracic CT scans. Moreover, the distribution of the radiation dose in the uterus was determined in order to obtain information about the ratio of internally and externally scattered radiation. Materials and Methods: The uterus doses during thoracic CT were determined by measuring organ doses using an Alderson-RANDO registered -Phantom and thermoluminescent dosimeters. A 0.25 mm lead equivalent protective apron was used to shield the abdominal area. Three measurement conditions were evaluated: without lead apron, covered with lead apron and wrapped with lead apron. The uterus dose with and without shielding describes the mean value and standard deviation of all examinations and all measurement points in the organ. Results: The uterus dose by thoracic CT was measured to be approximately 66.5 ± 3.1 μGy. If the abdomen is covered with a 0.25 mm Pb equivalent lead apron in the front area and on both sides, the uterus dose is reduced to 49.4 ± 2.8 μGy (26 % reduction, p < 0.001). If a lead apron is wrapped around the abdomen, providing 0.50 mm Pb shielding in the anterior section due to overlap, and 0.25 mm Pb in the posterior section and on both sides, the uterus dose is reduced even more to 43.8 ± 2.5 μGy (34 % reduction, p < 0.001). The dose distribution when the lead apron covers the abdomen shows that the shielding is effective for the scatter radiation that comes from the anterior part. Moreover, the wrapped apron protects the uterus from all directions and is even more effective for dose reduction than the covering apron. Conclusion: Our findings demonstrate that protective aprons are an effective dose reduction technique without additional costs and little effect on patient examination time. (orig.)

    Full Text Available Uterus didelphys is one of the congenital uterine anomalies due to defective medial fusion of mullerian ducts. This anomaly is known to have poor reproductive outcome and women with this condition often have to be treated for infertility. Multiple gestation is rare with this condition. An 18 years old primigravida presenting with threatened abortion at eight weeks, was found to have uterus didelphys. She was managed conservatively, aborted one of the fetuses at 16weeks of gestation, and went till term to deliver a healthy baby by cesarean section.

    The success of radiotherapy in dealing with cancer of the cervix lies in the understanding of its natural history and staging as well as the major forms of treatment. It is, therefore, imperative that all gynecological and radiation oncologists have at their command a thorough understanding of carcinoma of the cervix

    To assess whether cesarean delivery changes the natural position of the uterus. In this retrospective Institutional Review Board-approved cohort study, we conducted a search of our university gynecologic ultrasonography (US) database. Patients with transvaginal US images before and after either vaginal or cesarean delivery between 2012 and 2015 were included. Women with prior cesarean delivery were excluded. Two readers independently measured antepartum and postpartum flexion angles between the longitudinal axis of the uterine body and the cervix. We calculated intraclass correlation coefficients to measure inter-reader agreement. Antepartum and postpartum uterine flexion angles were compared between patients with vaginal and cesarean delivery. We included 173 patients (107 vaginal and 66 cesarean delivery). The mean interval between scans ± SD was 18 ± 10 months. Inter-reader agreement for flexion angles was almost perfect (intraclass correlation coefficients: antepartum, 0.939; postpartum, 0.969; both P cesarean delivery (154.8° ± 45.7°) versus vaginal delivery (145.8° ± 43.7°; P = .216). Mean postpartum flexion angles were higher after cesarean delivery (180.4° ± 51.2°) versus vaginal delivery (152.8° ± 47.7°; P = .001. Differences in antepartum and postpartum flexion angles between cesarean and vaginal delivery were statistically significant (25.6° versus 7.0°; P = .027). Cesarean delivery can change the uterine flexion angle to a more retroflexed position. Therefore, all women with a history of cesarean delivery should undergo a transvaginal US examination before any gynecologic surgery or intrauterine device placement to reduce the possibility of surgical complications. © 2017 by the American Institute of Ultrasound in Medicine.

    Cervix-cancer is the third most common female cancer worldwide. It is the leading cancer among Indian females with more than million new diagnosed cases and 50% mortality, annually. The high mortality rates can be attributed to late diagnosis. Efficacy of Raman spectroscopy in classification of normal and pathological conditions in cervix cancers on diverse populations has already been demonstrated. Our earlier ex vivo studies have shown the feasibility of classifying normal and cancer cervix tissues as well as responders/non-responders to Concurrent chemoradiotherapy (CCRT). The present study was carried out to explore feasibility of in vivo Raman spectroscopic methods in classifying normal and cancerous conditions in Indian population. A total of 182 normal and 132 tumor in vivo Raman spectra, from 63 subjects, were recorded using a fiberoptic probe coupled HE-785 spectrometer, under clinical supervision. Spectra were acquired for 5 s and averaged over 3 times at 80 mW laser power. Spectra of normal conditions suggest strong collagenous features and abundance of non-collagenous proteins and DNA in case of tumors. Preprocessed spectra were subjected to Principal Component-Linear Discrimination Analysis (PCLDA) followed by leave-one-out-cross-validation. Classification efficiency of ~96.7% and 100% for normal and cancerous conditions respectively, were observed. Findings of the study corroborates earlier studies and suggest applicability of Raman spectroscopic methods in combination with appropriate multivariate tool for objective, noninvasive and rapid diagnosis of cervical cancers in Indian population. In view of encouraging results, extensive validation studies will be undertaken to confirm the findings.

    Objectives: To establish the cytological criteria to identify the urothelial cells in cervical smears in order to avoid mistakes in the cytological diagnosis. Materials and Methods: Cervical smears from 34 post menopausal women with vesicovaginal fistulas, advanced bladder prolapse and genital erosive lichen planes (vulvar kraurosis) (Group 1) and transitional cell metaplasia of the cervix (TCM, Group 2) were stained with Papanicolaou technique. The cervical samples were taken during the routine annual examination for prevention of the uterine cancer. Results: The smears of cervix from Group 1 showed urothelial cells from the three layers of the transitional epithelium. The umbrella cells are the bigger ones with relatively large nuclei. Frequently, they are multinucleated with single or multiple nucleoli and a typical “frothy” cytoplasm (cytoplasmic vacuoles). The cells of the Group 2 showed nuclei with oval to spindled shapes, some tapered ends, less cytoplasm than squamous metaplastic cells, powdery chromatin, small nucleoli and nuclear grooves. Conclusions: The umbrella cells may be mistaken for dysplastic cells originating in low grade squamous intraepithelial lesions lesions (LSILs) due to their nuclear and cytoplasm sizes. Therefore, it is important to know the possibility of their appearance in the cervical smears, especially in post menopausal patients in order to avoid a false diagnosis of an intraepithelial lesion. It is unlikely that deeper cells of urothelium would be confused with high grade squamous intraepithelial lesion (HSIL) cells. However, their presence might be a reason of mistake in the diagnosis. TCM is an under-recognized metaplastic phenomenon of the cervix and vagina, which is a mimicker of high-grade squamous intraepithelial lesion. The differential characteristic between umbrella cells, cells from TCM and the deeper urothelial cells, and LSIL and HSIL are detailed in the present paper. PMID:22438615

    Disclosed is an apparatus for treating carcinoma of the uterine cervix by judiciously applying radioactive material immediately adjacent the uterine cervix for an extended period of time empirically determined by the radiologist. The novel apparatus comprises three radioactively chargeable components including a central tubular tandem vaginally insertable longitudinally into the uterine cervix and two non-lineal tubular ovoidal assemblies longitudinally locatable at the cervix and positioned laterally between the respective vaginal walls and the uterine cervix. The ovoidal assemblies are conveniently removably and pivotably connected to the central tandem component externally of the vaginal along the sagittal plane through a novel adapter member whereby the radioactively chargeable ovoidal assemblies tend to remain within a laterally extending plane located substantially midway the transversely separated vasicovaginal and rectovaginal septa, even though the patient periodically shifts her reclining posture during the extended treatment by said vaginally protruding apparatus

    Cervix cancers declined in most developed countries in recent years, but remain, the third worldwide leading cause of cancer death in women. A precise staging, based on clinical exam, an abdominal and pelvic MRI, a possible PET-CT and a possible lymph node sampling is necessary to adapt the best therapeutic strategy. In France, the treatments of tumors of less than 4 cm without nodal involvement are often based on radiotherapy followed by surgery and, whereas tumors larger than 4 cm and involved nodes are treated with concurrent chemoradiotherapy. Based on an illustrated clinical case, indications, delineation, dosimetry and complications expected with radiotherapy are demonstrated. (authors)

    Primary primitive neuroectodermal tumors (PNETs) are rare and high-grade malignant tumors that mostly occur in children and young adults. The most common sites are the trunk, limbs, and retroperitoneum. Herein, we present a case of a PNET involving the cervix uteri in a 27-year-old woman. The lesion showed characteristic histologic features of a PNET and was positive for the immunohistochemical markers cluster of differentiation (CD) 99, vimentin, neuron-specific enolase, neural cell adhesion molecule 1 (CD56), and CD117 (c-kit), further defining the tumor while helping to confirm PNET. The clinical Stage IIIB tumor was treated with chemotherapy and radiotherapy. PMID:23836982

    The effect of ionizing radiation on the reproductive organs of sheep was studied after a single local irradiation of ovaries with different X-ray doses. 22 sheep of the Slovak Merino breed, two years old, weighing an average of 30 kg, divided into four groups were irradiated as follows: group I n=6, 4.78 Gy (500 R), group II n=6, 9.67 Gy (1000 R), group III n=6, 19.14 Gy (2000 R). The sheep in the fourth (control) group were not irradiated but underwent laparotomy. Trypsin inhibition activity of the blood plasma and of the cervical mucus was determined from the decreased rate of hydrolysis of the low-molecular substrate (TAPA); the thickness of the epithelium of the cervix and body of the uterus was measured microscopically following fixation and colouring. The dynamics of TIA changes in the cervical mucus differed in the individual groups in the course of days 10, 30 and 100. The dynamics of changes in the thickness of the epithelium of the endometrium, the cervix and the uterus horns had a different character. On day 100 after irradiation the values differed only very little. The dynamics of TIA of the blood plasma (total and low-molecular fraction) differed between the groups and on day 100 of the experiment the values were significantly lower than on day 1. A comparison of the values in irradiated and control sheep showed that the values of TIA of the cervical mucus increased between days 10 and 30 while the values of low-molecular TIA of the plasma decreased.

    Purpose: Substantial organ motion and tumor shrinkage occur during radiotherapy for cervix cancer. IMRT planning studies have shown that the quality of radiation delivery is influenced by these anatomical changes, therefore the adaptation of treatment plans may be warranted. Image guidance with off-line replanning, i.e. hybrid-adaptation, is recognized as one of the most practical adaptation strategies. In this study, we investigated the effects of soft tissue image guidance using on-line MR while varying the frequency of off-line replanning on the adaptation of cervix IMRT. Materials and method: 33 cervical cancer patients underwent planning and weekly pelvic MRI scans during radiotherapy. 5 patients of 33 were identified in a previous retrospective adaptive planning study, in which the coverage of gross tumor volume/clinical target volume (GTV/CTV) was not acceptable given single off-line IMRT replan using a 3 mm PTV margin with bone matching. These 5 patients and a randomly selected 10 patients from the remaining 28 patients, a total of 15 patients of 33, were considered in this study. Two matching methods for image guidance (bone to bone and soft tissue to dose matrix) and three frequencies of off-line replanning (none, single, and weekly) were simulated and compared with respect to target coverage (cervix, GTV, lower uterus, parametrium, upper vagina, tumor related CTV and elective lymph node CTV) and OAR sparing (bladder, bowel, rectum, and sigmoid). Cost (total process time) and benefit (target coverage) were analyzed for comparison. Results: Hybrid adaptation (image guidance with off-line replanning) significantly enhanced target coverage for both 5 difficult and 10 standard cases. Concerning image guidance, bone matching was short of delivering enough doses for 5 difficult cases even with a weekly off-line replan. Soft tissue image guidance proved successful for all cases except one when single or more frequent replans were utilized in the difficult cases

  19. A simplified cervix model in response to induction balloon in pre-labour

    Science.gov (United States)

    2013-01-01

    Background Induction of labour is poorly understood even though it is performed in 20% of births in the United States. One method of induction, the balloon dilator applied with traction to the interior os of the cervix, engages a softening process, permitting dilation and effacement to proceed until the beginning of active labour. The purpose of this work is to develop a simple model capable of reproducing the dilation and effacement effect in the presence of a balloon. Methods The cervix, anchored by the uterus and the endopelvic fascia was modelled in pre-labour. The spring-loaded, double sliding-joint, double pin-joint mechanism model was developed with a Modelica-compatible system, MapleSoft MapleSim 6.1, with a stiff Rosenbrock solver and 1E-4 absolute and relative tolerances. Total simulation time for pre-labour was seven hours and simulations ended at 4.50 cm dilation diameter and 2.25 cm effacement. Results Three spring configurations were tested: one pin joint, one sliding joint and combined pin-joint-sliding-joint. Feedback, based on dilation speed modulated the spring values, permitting controlled dilation. Dilation diameter speed was maintained at 0.692 cm·hr-1 over the majority of the simulation time. In the sliding-joint-only mode the maximum spring constant value was 23800 N·m-1. In pin-joint-only the maximum spring constant value was 0.41 N·m·rad-1. With a sliding-joint-pin-joint pair the maximum spring constants are 2000 N·m-1 and 0.41 N·m·rad-1, respectively. Conclusions The model, a simplified one-quarter version of the cervix, is capable of maintaining near-constant dilation rates, similar to published clinical observations for pre-labour. Lowest spring constant values are achieved when two springs are used, but nearly identical tracking of dilation speed can be achieved with only a pin joint spring. Initial and final values for effacement and dilation also match published clinical observations. These results provide a framework for

    This is a retrospective analysis of the results of 24 patients with bulky stage 2 carcinoma of the cervix treated with full course irradiation followed by adjunctive surgery between 1975 and 1980. A review of the surgical specimens following irradiation showed that 12 patients had no residual cancer, five had only microscopic foci of cancer, and five had extensive residual cancer. Two patients had unresectable persistent cancer. Six patients had histological evidence of lymph node metastases prior to irradiation. The surgical-pathological findings following irradiation had important prognostic implications. All five patients with extensive residual cancer in the surgical specimen recurred, 2 of 5 patients with only microscopic foci of residual cancer and, none of the 12 patients with no residual cancer in the resected specimens developed a recurrence. Lymph node involvement was not associated with an increased incidence of recurrence. Most patients with residual cancer following full course irradiation recurred locally. Thus the addition of adjunctive surgery following full course irradiation did not significantly improve the treatment results of patients with bulky stage 2 carcinoma of the cervix.

    Rhabdomyosarcoma has known as a highly malignant soft tissue sarcoma. It has been the most common soft tissue sarcoma in childhood, accounting for about 3 to 4 % of all cases of childhood cancer. Rhabdomyosarcoma was rare in adults, accounting for 3% of all soft-tissue sarcomas. embryonal rhabdomyosarcoma of female genital tract including uterine cervix in an adult was rare. This study has reported a 33-year-old woman presented with abnormal vaginal discharge. Gynecologic examination revealed a cervical mass with grape- like feature protruding into vagina with posterior- superior vaginal wall involvement. Biopsy has performed and pathologic examination was consistent with embryonal botryoid type rhabdomyosarcoma. She has undergone the staging work up measurements including thoracic computed tomography (CT) scan, abdominopelvic magnetic resonance imaging (MRI), bone scan and bone marrow examination. In exception of abdominopelvic MRI, with 2 suspicious pelvic lymph nodes in addition of cervical mass, all others were normal. Radical hysterectomy with lymph node debulking and ovarian preservation has performed. Final results have shown embryonal botryoid type rhabdomyosarcoma of cervix. ovaries, endometrium, parametrium, and follopian tubes were unremarkable. Pelvic lymph nodes pathology and intraabdominal fluid cytology were negative for malignancy. Lymphovascular invasion was identified. She has advised for adjuvant chemotherapy. This case has reminded that embryonal rhabdomyosarcoma could occur in uncommon site and older female. Longer follow up of these cases has required due to lack of survival data for embryonal rhabdomyosarcoma of this site and age group.

    2014-01-01

    Full Text Available Background: Carcinoma of cervix is the most common malignancy in female and a major public health problem worldwide. It is the leading cause of death from cancer among women in low resource settings. In Bangladesh, mortality rate is high as most of the cases with cervical cancer are diagnosed in advanced stage. World Health Organization considers cervical cancer as a preventable disease as it can be identified in preinvasive stage. Considerable efforts have been given in detection and treatment of the condition all over the world. A number of cervical cancer screening tests are available. Among them, visual inspection of cervix with acetic acid is rational and can be competently performed by physicians with proper training. Objective: To find out the feasibility of the visual inspection of cervix with acetic acid for the detection of the precancerous lesions of the cervix in our country. Materials and Methods: This cross sectional, analytical study was carried out among the patients attending the outpatient department of Bangabandhu Sheikh Mujib Medical University (BSMMU who were VIA positive and sent for colposcopy in the colposcopy clinic in the department of Obstetrics and Gynecology in BSMMU from June to December 2004. Two hundred samples were considered for this study. Results: Out of 200 cases, colposcopically 85% had CIN and invasive lesions, 4% had inflammatory lesions while 11% had normal findings. Colposcopy directed punch biopsy revealed positive lesions in 81%, 4% had inflammatory lesions while 15% had normal findings. Conclusion: The study concluded that VIA and colposcopy are the important methods in the evaluation of cervical premalignancy. VIA may be an important tool for screening of cervical cancer in low resource settings as it is simple, easy to perform and cost-effective. After screening, VIA positive cases must be referred for colposcopic evaluation. We can screen cervical cancer by VIA all over the country and thus reduce

    A study was undertaken to know better the effects of venlafaxine hydrochloride on the responses of isolated rat vas deferens to noradrenaline and dopamine, those of isolated rat uterus to serotonin and histamine, and those of isolated guinea-pig ileum to acetylcholine and histamine. Venlafaxine hydrochloride increased the response of rat vas deferens to noradrenaline but not to dopamine. Venlafaxine did not alter the response of rat isolated uterus to serotonin. In rat uterus, venlafaxine did not modify the response to histamine but was able to increase it in guinea-pig ileum. An anticholinergic effect was observed with the lowest concentration tested. Although venlafaxine is a selective serotonine reuptake inhibitor in the central nervous system, serotonin uptake was not seen in the rat uterus. The anticholinergic effects observed in the present study might be consistent with some of the side-effects associated with venlafaxine.

    Using MR imaging with a body coil parametrial invasion was determined prospectively in 169 consecutive patients considered on the basis of clinical examination to have carcinoma confined to the cervix. After radical hysterectomy correlation with histologic examination was performed for the left and right parametrium separately. The criterion for parametrial invasion was a high-signal-intensity lesion with disruption of the full thickness of the cervical stroma combined with areas of abnormal signal intensity within the parametrial region on T2-weighted images. Histologic examination showed that 18 parametria in 13 patients were invaded by tumor. MR had an overall accuracy of 93%, a sensitivity of 89%, and a specificity of 93% in demonstrating parametrial involvement. Positive and negative predictive values were 43% and 99%. The main weakness of MR was 21 false-positive tests. This represents a limitation when MR is performed with a body coil. (orig.)

    Full Text Available Round ligament of uterus leiomyoma is a rare, benign tumor of the vulva. Its incidence is not known exactly, and the mean age ranges from 13 to 70. Although clinical properties of benign and malignant diseases in the vulvar area are frequently similar, early diagnosis and treatment are essential. Local excision is recommended as definitive therapy. We present an 28-year-old female without any birth with a mass in anterior vaginal wall diagnosed as vulvar leiomyoma. In conclusion, a brief review of relevant literature emphasizes that leiomyomas are quite rare outside of the uterus but they might occur in any tissue or organ containing smooth muscle, spontaneously or parasitically after the spreading effect of an accident or surgical trauma. Clinicians should be alert especially for the diagnosis in a tissue with smooth muscle content.

    Full Text Available Uterine torsion during pregnancy is only sporadically reported in the literature. Here we present a case of leiomyoma causing uterine torsion in pregnancy and review the literature on etiology, diagnosis, and management. A 25-years-old primigravida with leiomyoma complicating pregnancy was admitted in our hospital with abdominal pain and uterine tenderness. She underwent emergency LSCS (lower segment cesarean section for fetal bradycardia. Intraoperatively, the uterus was rotated 180 degrees left to right. Inadvertent incision on the posterior wall was avoided by proper delineation of anatomy. Torsion was corrected by exteriorization of leiomyoma and uterus, and lower segment cesarean was carried out safely. Prompt recognition and management of this condition is necessary for better maternal and fetal outcome.

    A prospective study to investigate a group of Iraqi woman with proved genital vulval warts, to seek evidence of human papillomavirus infection in apparently normal looking cervixes and to investigate the natural history of infection. From December 1997 to August 1998, 20 women with vulval warts were enrolled along with 20 aged-matched control cases without warts. Their ages ranged between 19-48 years with a mean of 30.4 years, (+/- standard deviation = 2.3) for patients and 18-48 years with a mean of 29.7 (+/- standard deviation = 2.7) for the control group. General and gynecological examinations were carried out. Cervical swabs for associated genital infection, papilloma smears, speculoscopy and directed punch biopsies were carried out to detect subclinical human papillomavirus infections of the cervix and associated intraepithelial neoplasm. Cytology results showed that 11 (55%) of patients had evidence of cervical infection by human papillomavirus, 6 (30%) showed mild dysplastic changes, 3 (15%) showed moderate dysplastic changes, whilst 2 (10%) showed no dysplastic changes. Speculoscopy and acetowhitening was positive in 11 (55%) and collated histological results showed evidence of human papillomavirus infection in 9 patients (45%). As for the control group one case (5%) had evidence of human papillomavirus infection. Subclinical human papillomavirus infection is more common than was previously thought among Iraqi women. It may appear alone or in association with vulval or exophytic cervical warts, or both, and may be more common than the clinically obvious disease. Speculoscopy as an adjunctive method to colposcopy was found to be a simple and an easy to perform technique. Its combination with cytology gave relatively good results when it was used as a triage instrument, and may have a more promising performance in the future. (author)

    Virtual reality models of human organs are needed in surgery simulators which are developed for educational and training purposes. A simulation can only be useful, however, if the mechanical performance of the system in terms of force-feedback for the user as well as the visual representation is realistic. We therefore aim at developing a mechanical computer model of the organ in question which yields realistic force-deformation behavior under virtual instrument-tissue interactions and which, in particular, runs in real time. The modeling of the human uterus is described as it is to be implemented in a simulator for minimally invasive gynecological procedures. To this end, anatomical information which was obtained from specially designed computed tomography and magnetic resonance imaging procedures as well as constitutive tissue properties recorded from mechanical testing were used. In order to achieve real-time performance, the combination of mechanically realistic numerical uterus models of various levels of complexity with a statistical deformation approach is suggested. In view of mechanical accuracy of such models, anatomical characteristics including the fiber architecture along with the mechanical deformation properties are outlined. In addition, an approach to make this numerical representation potentially usable in an interactive simulation is discussed. The numerical simulation of hydrometra is shown in this communication. The results were validated experimentally. In order to meet the real-time requirements and to accommodate the large biological variability associated with the uterus, a statistical modeling approach is demonstrated to be useful.

    Full Text Available Uterus transplantation (UTx is the only available treatment for absolute uterine factor infertility (AUFI, which is caused by either absence (congenital or after hysterectomy or presence of a non-functioning uterus. Uterus transplantation became a clinical reality after more than 10 years of structured animal-based research. Aside from gestational surrogacy, this procedure is the only alternative for women with AUFI to attain genetic motherhood. In the Middle East, North Africa and Turkey (MENAT region, out of a population of around 470 million, more than 100,000 women of fertile age are estimated to suffer from AUFI. Introduction of UTx as an infertility treatment in this region will certainly differ in specific countries from ethical, religious and legal standpoints depending on culture and religion. The MENAT region is the cradle of three religions and the geographic area encompasses a variety of cultures and religions with different views on assisted reproduction. In light of these issues, the aim of this article is to give an overview of the research-based development of UTx and its clinical results up until today as well as to explore how UTx would fit into current infertility treatments in the MENAT region, with its existing multifaceted religious perspectives.

    A case of postirradiation sarcoma is described. The tumor, a malignant fibrous histiocytoma, occurred in the radiation field 11 years following postoperative external beam radiation therapy (7,000 rad) for carcinoma of the cervix. Reports of postirradiation malignant fibrous histiocytoma are rare, and the occurrence of this neoplasm following treatment for cervix cancer has not previously been described. The literature concerning postirradiation bone and soft tissue sarcomas is briefly reviewed, with special attention to malignant fibrous histiocytomas. (author)

    Carcinoma of cervix is the most common cancer found among the women of India. Though cervical cytology screening was effective in preventing carcinoma of cervix in developed nations, it is considered unsuitable in developing countries. Recent research has established an etiological link between human papillomavirus infection and carcinoma of cervix. In this review, an attempt is made to answer the question, 'whether carcinoma of cervix can be prevented with human papillomavirus vaccine?' Literature search using Pubmed and Medline was carried out and relevant articles were reviewed. There is ample experimental evidence to show that DNA of human papillomavirus integrates with cervical cell genome. Viral genes E6 and E7 of HPV type 16 and 18 inactivate p53 function and Rb gene, thus immortalize the cervical epithelial cells. Recombinant vaccines blocked the function of E6 and E7 genes preventing development of papillomas in animals. Vaccination with HPV-VLPs encoding for genes of E6 and E7 neutralizes HPV integrated genome of malignant cells of uterine cervix. Based on experimental evidence, it is possible to prevent carcinoma of cervix with human papillomavirus vaccine, Further research is necessary to identify a effective and safe HPV vaccine, routes of administration and characteristics of potential beneficiaries.

    Cadmium (Cd) and arsenic (iAs) are toxic metals ubiquitously present in the environment. Both pollutants exert nonmonotonic dose responses, being mostly cytotoxic at high concentrations but mimicking estrogen (E2) effects at low doses. Xenoestrogenic activity of Cd and iAs has been demonstrated in different hormone-dependent tumor cell lines; however, their actions in vivo remain largely unknown. Here, we investigated whether in vivo administration of low doses of Cd and iAs through drinking water would display xenoestrogenic effects in the anterior pituitary gland and uterus of ovariectomized rats. Cd (1ppm) and iAs (0.1ppm) exposure increased the wet weight of anterior pituitary gland and uterus and induced proestrus- and estrus-like vaginal smears. Both metals stimulate cell proliferation of these tissues as they increased the expression of proliferation markers. More importantly, they augmented soluble guanylyl cyclase α1 subunit expression, which has been linked to hormone-dependent tumor progression. Also, Cd and iAs modified protein levels of full-length estrogen receptor α and its truncated variants in an E2-like manner. Anterior pituitary hormone secretion was differentially affected by both metals. Luteinizing hormone synthesis and release were strongly diminished after Cd exposure and only mildly reduced by iAs. Both metals were able to increase prolactin synthesis, although only iAs augmented serum prolactin levels. This study shows for the first time that Cd and iAs exert strong xenoestrogenic effects on anterior pituitary gland at low doses. The differences between Cd and iAs E2-like behavior indicate that other Cd- and iAs-specific mechanisms could be involved. Altogether, these results contribute to the knowledge of reproductive disorders associated with Cd and iAs environmental contamination. © 2016 Society for Reproduction and Fertility.

    Can surgical reconstruction of the cervix and vagina in patients be achieved using an acellular porcine small intestinal submucosa (SIS) graft? Our experiences of combined laparoscopic and vaginal cervicovaginal reconstruction using an SIS graft in eight patients were positive, with successful reconstruction and no complications, cervical stenosis or vaginal stenosis. In patients with agenesis and dysgenesis of the uterine cervix and vagina, surgical reconstruction of the internal genitalia is a challenging problem for gynecologists. Hysterectomy with the creation of an artificial vagina was the treatment of choice in the 1990s. Recently, conservative management has been gradually adopted to avoid extirpation of the uterus, including the canalization techniques, the uterovaginal anastomosis and the reconstruction of cervical and vaginal agenesis with some autologous tissues. This prospective observational study from January 2012 to March 2013 included 8 patients aged 10-18 years with malformation of the cervix (1 with cervical agenesis, 1 with a cervical body consisting of a fibrous band and 6 with obstruction of the cervical os) and vagina (4 with complete vaginal aplasia and 4 with a 1-3 cm long vaginal pouch) diagnosed by physical examination and magnetic resonance imaging. Eight patients underwent combined laparoscopic and vaginal cervicovaginal reconstruction using an SIS graft during the end of menstruation. A T-shaped intrauterine device connected with a 14-French Foley catheter was inserted into the uterine cavity to keep the newly created cervix patent, and then a permanent lower uterine cerclage was placed. Patients were assessed post-operatively at 1, 2, 4, 6, 12 and 15 months, and data on menstruation and the morphology of the neovagina and cervix were recorded. The mean ± SD age of the patients was 14.5 ± 2.8 (10-18) years. All patients had a history of cyclic abdominal pain, and the average delay in diagnosis was 4.5 ± 4.0 (0-12) months. One

    Full Text Available Introduction. The advantages of laparoscopic removal of a myoma over classical surgical technique are shorter hospital stay, rapid recovery and less pain after surgery, as well as a lower frequency of ileus and thromboembolic complications. The surgical technique of laparoscopic removal of myoma involves four basic stages: incision on the wall of the uterus, separation of the myoma from the healthy uterine tissue, to stop bleeding and removal of the myoma from the abdomen. Apart from these four basic stages, it is also necessary to establish a new integrity of the uterine wall, especially in women planning pregnancy. Objective. The aim of the paper is to present the procedures used in the treatment of uterine wall defect during the laparoscopic removal of the myoma. Methods. We analyzed 96 patients who were indicated for laparoscopic myomectomy. All patients were divided into four groups according to the type of the technique of haemostasis and treatment of the defect on the uterine wall: electrocoagulation, electrocoagulation with application of argon plasma, a single suture and extended suture. Results. In order to stop bleeding, we most often used electrocoagulation by monopolar electricity, i.e. in 39.6% of the patients. To stop bleeding and treat the defect of the uterine wall, we used a single suture in 21.9% and in 11.4% patients we used the extended suture. The manner of uterine wall treatment did not have a statistically significant influence on the results of haematological parameters (p>0.05, consumption of carbon dioxide (p>0.05 and the duration of surgical procedure (p>0.05. The increased use of antibiotics (p<0.05 in the group of patients in whom we treated the defect by sutures on the uterus, the length of postsurgical hospitalization and absence from work (p<0.01 was statistically significant. Conclusion. To achieve a better reconstruction of the uterus, it is recommended to use sutures with laparoscopic removal of myoma.

    Technical improvements in transducer design permit a direct coronal view of the uterus (''hysterographic view'') to be obtained with the bladder empty as a valuable complement to the usual US study of the pelvis with the bladder distended. Good visualization of the uterine cavity and wall is possible in 95% of cases. More than 50 cases of endometrial and myometrial pathology (polyps, cancers, submucous fibroids) with abnormalities inapparent on standard US scans have hysterographic and/or pathologic proof confirming the empty-bladder US-based diagnosis. If tubal visualization is not necessary, empty-bladder US may often avoid hysterography. It is also the best way to demonstrate IUD position

    In our department external irradiation is given priority over intracavitary (radium) therapy for the treatment of carcinoma of the cervix uteri. Our policy is to irradiate the volume containing the primary lesion, parametrium and pelvic lymph nodes to a dose of 40.0 Gy in about 4 weeks for stages I and IIa, or 50.0 Gy over 5 weeks for stages IIb and III. For stages I and IIa, intracavitary radium therapy is additionally given to a dose of 28.0-30.0 Gy at ''point A'', 7-10 days after the external irradiation, by means of two fractions with an interval of 7-10 days. For stages IIb and III, further external irradiation is carried out to give an additional dose of 20.0 to 25.0 Gy to the cervix and parametrium over 2 weeks by means of radiation fields of reduced size. If the size of the tumour in stages IIb and III is considerably reduced after the initial dose of 50.0 Gy, and the dose to point A is 40.0 Gy, intracavitary therapy is carried out without the additional small field irradiation. The intracavitary therapy is given twice with an interval of 8 days. For stage IV without distant metastases the treatment policy is the same as that in stage III; for stage IV with distant metastases, only whole pelvis irradiation is performed, to a dose of 50.0 Gy over 5 weeks

    The uterus is the most recent addition to the list of organs that can be successfully transplanted in humans. This article analyzes living donor uterus transplantation according to the ethical principle of equipoise. A comparison is made between living donor uterus transplantation and gestational surrogate motherhood. Both are solutions to absolute uterine infertility that allow the transfer of genetic material from intended parents to a child. The analysis concludes that living donor uterus transplantation does not violate the ethical principle of equipoise and should be considered an ethically acceptable solution to absolute uterine infertility. © 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

    To explore spatial variability within the cervix and the sensitivity of shear wave speed (SWS) to assess softness/stiffness differences in ripened (softened) vs unripened tissue. We obtained SWS estimates from hysterectomy specimens (n = 22), a subset of which were ripened (n = 13). Multiple measurements were made longitudinally along the cervical canal on both the anterior and posterior sides of the cervix. Statistical tests of differences in the proximal vs distal, anterior vs posterior and ripened vs unripened cervix were performed with individual two-sample t-tests and a linear mixed model. Estimates of SWS increase monotonically from distal to proximal longitudinally along the cervix, they vary in the anterior compared to the posterior cervix and they are significantly different in ripened vs unripened cervical tissue. Specifically, the mid position SWS estimates for the unripened group were 3.45 ± 0.95 m/s (anterior; mean ± SD) and 3.56 ± 0.92 m/s (posterior), and 2.11 ± 0.45 m/s (anterior) and 2.68 ± 0.57 m/s (posterior) for the ripened group (P < 0.001). We propose that SWS estimation may be a valuable research and, ultimately, diagnostic tool for objective quantification of cervical stiffness/softness. Copyright © 2013 ISUOG.

    Uterine cervix carcinomas spread by direct local extension, lymphatic permeation and hematogenous dissemination. Their metastatic foci are closely related to iliopsoas compartment anatomically no matter what the pattern of spread is. Therefore, iliopsoas involvement in uterine cervix cancer may occur frequently. The authors reviewed pelvis CT of 218 cervix cancer patients for recent one year from March 1986 to February 1987 at Seoul National University Hospital. Among them, 10 cases showed iliopsoas involvement. Pattern of iliopsoas involvement was classified into four types: infiltrative type (three cases), localized mass type (three cases), mass with bone destruction type (two cases), paraaortic lymphadenopathy type (two cases). In all cases except 3 cases of infiltrative type, lymphadenopathy or bone metastasis adjacent to iliopsoas lesion was identified. And this finding suggested that the route of iliopsoas involvement in cervix cancer would be secondary infiltration from metastatic focus of adjacent lymph node or bone. Recognition of iliopsoas involvement of cervix caner may prevent misdiagnosis and predict the degree of disease dissemination

    Purpose: To review the radiation therapy 'box' technique for cancer of the cervix by means of magnetic resonance imaging (MRI), lymphangiography, and anatomic studies on cadavers. Methods and Materials: From 1993 to 1996, the anatomic borders of the 'box' technique used at our Radiation Oncology Department--the superior border of the AP-PA fields at the inferior edge of L4; the inferior border at the inferior edge of the ischium; the lateral borders placed 2.5 cm outside of the bony pelvis rim; the anterior border of the lateral fields over the anterior edge of the pubic symphysis; and the posterior at the S2-S3 interspace - were reviewed in 35 sagittal MRI and 10 lymphangiographies of patients with FIGO IB (6), IIA (6), IIB (19), IIIB (3), and IVA (1). An anatomic revision was conducted on 30 cadavers to identify aortic bifurcation, lymphatic nodes, and uterus flexion. Results: In 50% of the patients with FIGO IB, the posterior border of the lateral field was inadequate to encompass the planning target volume (PTV), and in 67% with Stage IIA. In IIB, the anterior border was inadequate in 1 patient, and the posterior in 8 (42%). In IIB and IVA patients, the PTV was not encompassed. When correlating the anterior and posterior borders of the lateral field and the treatment volume in the 35 sagittal MRIs, the posterior border of the lateral field was inadequate in 49%, and the anterior border in 9% of the cases. According to the lymphangiography, the portals encompassed the external iliac nodes. Dissected female pelvises revealed that the aortic bifurcation occurred at the level of the inferior L4 edge in 80% of the cadavers. There was no correlation between uterus flexion in MRIs and in cadavers. Conclusion: The design of the lateral fields of the four-field technique for the irradiation of the uterine cervix based on anatomic bone references failed to encompass the planning-target volume in a significant number of patients

    Full Text Available Forty eight gilts with average body weight of 107.83 ± 5.08 kg were used in experiments to study the use of pregnant mare serum gonadotrophin (PMSG and human chorionic gonadotrophin (hCG as superovulation agent in gilts to increase piglet production. Four groups of twelve gilts were injected with PMSG dan hCG dose levels of 0, 600, 1200, and 1800 IU/gilt. Injections were conducted three days before estrus. During gestation, gilts were placed in colony pigpens. On days 15, 35, and 70 of gestation, gilts were slaughtered in order to measure the number of corpus luteum, growth and development of the uterus and placenta. Blood samples were collected to determine progesterone and estradiol concentrations. The resuts showed that superovulation dose levels of 600 to 1200 IU/gilt increased progesterone and estradiol secretions, growth and development of the uterus and placenta in gestation ages of 15, 35, and 70 days. It is concluded that superovulation with dose of 600 to 1200 IU can improve the gilts reproduction.

    Full Text Available Background and objectives: Over the centuries, herbal drugs have been used as major sources of medicine for the prevention and treatment of diseases. In recent years, there has been an exponential growth in the field of herbal medicines and these drugs are gaining popularity both in developing and developed countries because of their natural origin and less side effects. The present research has been undertaken to formulate and evaluate an herbal gel for uterus flux based on Iranian traditional medicine references. Methods: An aqueous extracts of fruit peels of Punica granatum and leaves of Myrtus communis, ethanol extract of oleo gum resins of Boswellia carterii and hydro-alcoholic extract of Carum carvi fruits were obtained. The gel was prepared by using the plants extract, carbopol 940, propylene glycol, tri-ethanolamine and distilled water. Further, the prepared gel was evaluated for physicochemical and microbial characteristics. Moreover, accelerated laboratory stability tests were performed. Results: The results showed good appearance and homogeneity of the gel. It was yellow-brown in color with acceptable physicochemical characteristics. Besides, the gel was stable towards physical changes and successfully passed microbiological tests. Conclusion: The prepared gel contained tannins which are astringent agents; therefore, this product could be an appropriate candidate for disorders like uterus flux with respect to its traditional use.

    The study was carried out in 70 cases of carcinoma cervix uteri, showing varying degree of proctitis following radiotherapy treatment for cervical cancer. Grossly, the rectal mucosa showed oedema, congestion, granular proctitis, ulceration, and microscopically stromal connective tissue as well as epithelial changes. The stromal changes have been emphasised as useful diagnostic criteria of radiation reaction. The familarity of these changes is considered necessary because it is imperative to know categorically that a given lesion is entirely or in part due to radiation or due to extension of adjacent tumour in the cervix. Further, this issue is very important in management of cases of cancer cervix. The criteria of distinguishing the lesions in the rectal tissue have been laid down. (auth.)

    On the basis of investigating the peripheral blood lymphocytes the immunologic state in 81 patients with uterine cervix carcinoma is estimated. It is established that there is a considerable decrease of indices in the T-immune system in patients with uterine cervix carcinoma. The detection of reductions in the immunogram indices in the initial stage plays a definte diagnostic role in the detection of metastases, permits to forecast the process generalization, and consequently, to determine the treatment tactics. It is established that under the effect of combined radiation treatment the T-system is mostly injured. Consequently, pronounced postradiation depression is prognostically unfavourable. The examination of another group of patients has shown that the probability of development of lymphogenic metastases in uterine cervix carcinoma is mainly determined by immuno-morphological peculiarities of regional lymph nodes [ru

    A group of patients with uterine cervix carcinoma with metastatic indices in regional lymphatic vessels detected on lymphograms is studied. It is established that after radiation treatment the relative resistance of lymphogenic metastases to the ionizing radiation is found in 14.9% patients. Extraperitoneal removal of regional lymphatic collectors after a complete course of combined radiation therapy in patients with uterine cervix carcinoma with histologically proved metastases improves 3-year results of survival up to 40%. In the case of multiple and bilateral metastatic injury of regional lymph nodes the therapeutic value of extraperitoneal lymphadenectomy reduces sharply. The diagnostic value of X-ray contrast lymphography not only for defining regional metastases, but for planning and carrying out the treatment of patients with uterine cervix carcinoma is pointed out [ru

  6. Human cathelicidin production by the cervix.

    Directory of Open Access Journals (Sweden)

    Lorraine Frew

    Full Text Available hCAP18/LL-37 is the sole human cathelicidin; a family of host defence peptides with key roles in innate host defence. hCAP18/LL-37 is expressed primarily by neutrophils and epithelial cells, but its production and function in the lower genital tract is largely uncharacterised. Despite the significant roles for cathelicidin in multiple organs and inflammatory processes, its impact on infections that could compromise fertility and pregnancy is unknown. The aim of this study was to investigate cathelicidin production, regulation and function in the cervix. hCAP18/LL-37 was found to be present in cervicovaginal secretions collected from women in the first trimester of pregnancy and to be expressed at significantly higher levels in samples from women with alterations in vaginal bacterial flora characteristic of bacterial vaginosis. In endocervical epithelial cell lines, expression of the gene encoding hCAP18/LL-37 (CAMP was not affected by TLR agonists, but was found to be up-regulated by both 1, 25 hydroxyvitamin D3 and 25 hydroxyvitamin D3. However, no association was found between serum levels of vitamin D and hCAP18/LL-37 concentrations in cervicovaginal secretions (n = 116. Exposure to synthetic LL-37 had a pro-inflammatory effect on endocervical epithelial cell lines, increasing secretion of inflammatory cytokine IL-8. Together these data demonstrate inducible expression of hCAP18/LL-37 in the female lower reproductive tract in vivo and suggest the capacity for this peptide to modulate host defence to infection in this system. Further investigation will elucidate the effects of hCAP18/LL-37 on the physiology and pathophysiology of labour, and may lead to strategies for the prevention of infection-associated preterm birth.

    Low-stage uterine cervix carcinoma can be treated by either surgery, radiation therapy or combined treatments with high cure rates ranging from 90 to 95 % for stage IB1 tumors. However, the standard treatment, combining external beam plus intracavitary radiation, fails to control the progression of the disease in 35 to 90 % of patients with locally advanced cervical cancer. No substantial improvements have been made in the treatment of these tumors in the past two decades. The addition of concurrent 5-FU in a phase III study failed to improve the results in the overall patient population, but the five-year DFS was significantly better in a subset of patients (tumor > 5 cm and IB/IIA or medial parametrial IIB disease). Concurrent chemo-radiation and adjuvant chemotherapy with epirubicin showed, in a phase III study, a significant longer DFS in patients treated with chemotherapy despite the same long-term local tumor control. After many phase II studies, five phase III studies have recently demonstrated a 40 to 60 % reduction in the relative risk of recurrence with cisplatin containing chemo-radiation. Across these studies, the risk of death was reduced by 30 to 50 %. The benefit was less clear in patients with stages III-IV tumors than in patients with lower stages associated with poor prognostic factors. Hematologic and gastrointestinal toxicity of chemo-radiation was greater than that of radiotherapy alone. However, late side effects were similar in the different treatment groups. These results must be confirmed with a longer follow-up. The importance of concurrent chemotherapy during the brachytherapy procedure should be analyzed. It has yet to be determined which chemotherapy regimen achieves the most favorable therapeutic ratio. (authors)

    Full Text Available Cervical sarcomas are extremely rare tumors associated with a poor prognosis. We report the case of a 63-year-old woman who was admitted to our institution due to abnormal vaginal bleeding and abdominal pain. Physical examination revealed a large cervical mass that was biopsied. Pathological features were compatible with a leiomyosarcoma of the uterine cervix. The patient underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy. All histological and Immunohistochemical findings confirmed the diagnosis of leiomyosarcoma of the cervix. Adjuvant chemotherapy was started but unfortunately the disease progressed and 1 year after completion of the chemotherapy the patient developed lung metastases and eventually died.

Clinical examination revealed longitudinal vaginal septum. Ultrasound scan revealed two endometrial cavities with a single cervix. Hysterosalpingogram revealed septum which had separated the endometrial cavity with no free spillage of contrast media on both fallopian tubes. Ultrasound KUB and intravenous urethrography did not reveal any abnormality in the urinary system. Resection of vaginal septum, hysteroscopic septoplasty and diagnostic laparoscopy were performed. Three months after the surgery, she was relieved from the symptoms. However, no comments on fertility issue can be made at the moment as the couple is practicing contraceptive methods.

    2002-12-25

    The current study examines 1) the sensitivity of detection and 2) sampling and screening/diagnostic error in the cytologic diagnosis of adenocarcinoma in situ (AIS) of the cervix. The data were taken from public and private sector screening laboratories reporting 25,000 and 80,000 smears, respectively, each year. The study group was comprised of women with a biopsy diagnosis of AIS or AIS combined with a high-grade squamous intraepithelial lesion (HSIL) who were accessioned by the Western Australian Cervical Cytology Registry (WACCR) between 1993-1998. Cervical smears reported by the Western Australia Centre for Pathology and Medical Research (PathCentre) or Western Diagnostic Pathology (WDP) in the 36 months before the index biopsy was obtained were retrieved. A true measure of the sensitivity of detection could not be determined because to the authors' knowledge the exact prevalence of disease is unknown at present. For the current study, sensitivity was defined as the percentage of smears reported as demonstrating a possible or definite high-grade epithelial abnormality (HGEA), either glandular or squamous. Sampling error was defined as the percentage of smears found to have no HGEA on review. Screening/diagnostic error was defined as the percentage of smears in which HGEA was not diagnosed initially but review demonstrated possible or definite HGEA. Sensitivity also was calculated for a randomly selected control group of biopsy proven cases of Grade 3 cervical intraepithelial neoplasia (CIN 3) accessioned at the WACCR in 1999. For biopsy findings of AIS alone, the diagnostic "sensitivity" of a single smear was 47.6% for the PathCentre and 54.3% for WDP. Nearly all the abnormalities were reported as glandular. The sampling and screening/diagnostic errors were 47.6% and 4.8%, respectively, for the PathCentre and 33.3% and 12.3%, respectively, for WDP. The results from the PathCentre were better for AIS plus HSIL than for AIS alone, but the results from WDP were

    Radiographic, historical, clinical signs, and surgical and histopathologic findings of six dogs with diagnosed cystic uterus masculinus are given. The condition was seen in aged dogs between 4 and 15 years (mean of 8.8 years). There was no breed predisposition, although the larger breeds were involved in this study. The predominant clinical signs were constipation, dysuria and anuria. Lateral survey recumbent abdominal radiographs coupled with negative-or positive-contrast cystography were useful in delineating the bladder and the urethra, thus revealing the smooth-contoured, asymmetrical fluid-filled viscus in the caudal abdomen. The bi-horned cysts were connected to the dorsal urethra through a short blind-ending pedicle. The nonseptic, aspermic, cystic fluid averaged 146.7 ml (range of 100–200 ml). The predominant epithelial lining cells seen were simple columnar to pseudostratified columnar

    Appropriate mechanical function of the uterine cervix is critical for maintaining a pregnancy to term so that the fetus can develop fully. At the end of pregnancy, however, the cervix must allow delivery, which requires it to markedly soften, shorten and dilate. There are multiple pathways to spontaneous preterm birth, the leading global cause of death in children less than 5 years old, but all culminate in premature cervical change, because that is the last step in the final common pathway to delivery. The mechanisms underlying premature cervical change in pregnancy are poorly understood, and therefore current clinical protocols to assess preterm birth risk are limited to surrogate markers of mechanical function, such as sonographically measured cervical length. This is what motivates us to study the cervix, for which we propose investigating clinical cervical function in parallel with a quantitative engineering evaluation of its structural function. We aspire to develop a common translational language, as well as generate a rigorous integrated clinical-engineering framework for assessing cervical mechanical function at the cellular to organ level. In this review, we embark on that challenge by describing the current landscape of clinical, biochemical, and engineering concepts associated with the mechanical function of the cervix during pregnancy. Our goal is to use this common platform to inspire novel approaches to delineation of normal and abnormal cervical function in pregnancy. PMID:25841293

    2013-01-01

    Background: Hypoxia can promote tumor metastasis by mechanisms that are believed to result from changes in gene expression. The current study examined the role of putative metastatic genes regulated by cyclic hypoxia in relation to metastasis formation in orthotopic models of cervix cancer. Methods: Orthotopic tumors derived from ME180 human cervix cancer cells or from early generation human cervix cancer xenografts were exposed to cyclic hypoxic conditions during growth in vivo and tumor growth and lymphnode metastases were monitored. Expression of the chemokine receptor CXCR4 and various genes in the Hedgehog (Hh) pathway were inhibited using genetic (inducible shRNA vs CXCR4) small molecule (AMD3100) or antibody (5E1) treatment (CXCR4 and Hh genes, respectively) during tumor growth. Results: As reported previously, exposure of tumor bearing mice to cyclic hypoxia caused a reduction of tumor growth but a large increase in metastasis. Inhibition of CXCR4 or Hh gene activity during tumor growth further reduced primary tumor size and reduced lymphatic metastasis to levels below those seen in control mice exposed to normoxic conditions. Conclusion: Blocking CXCR4 or Hh gene expression are potential therapeutic pathways for improving cervix cancer treatment

  13. Protease and protease inhibitory activity in pregnant and postpartum involuting uterus

    International Nuclear Information System (INIS)

    Milwidsky, A.; Beller, U.; Palti, Z.; Mayer, M.

    1982-01-01

    The presence of two distinct proteolytic activities in the rat uterus was confirmed with 14 C-labeled globin used as a sensitive protein substrate and following release of label into the trichloroacetic acid-soluble supernatant fraction. Protease I is a cytoplasmic acid protease while protease II is associated with the pellet fraction, can be extracted by 0.6 M sodium chloride, and is active at pH 7.0. Protease I activity is low during pregnancy and markedly increases at term achieving maximal activity at day 3 post partum with a subsequent decline to preterm activity values. Lactation did not affect the uterine protease I activity. Protease II activity is not significantly different during pregnancy, at term, and post partum. The presence of an inhibitor of protease I was suggested by a decrease in enzyme activity with an increased cytosolic protein concentration. The inhibitor also lessened bovine trypsin activity but had no effect on protease II. Although its inhibitory potency on trypsin fluctuated during the various uterine physiologic stages, these changes appeared to be statistically insignificant. Human uterine samples were also found to contain the two protease activities with similar changes in protease I post partum. It is suggested that, both in the rat and in man, uterine involution post partum is associated with a marked increase in activity of acid cytosolic protease, while a particulate neutral protease and a soluble inhibitor of trypsin, which are also present in uterine cells, do not appear to play a significant role in the dissolution of uterine tissues after parturition

  15. Value and importance of intracavitary therapy in uterine cervix carcinoma

    International Nuclear Information System (INIS)

    Frischkorn, R.

    1986-01-01

    The guiding topic of this report was 'the value and importance of intracavitary therapy in uterine cervix carcinoma'. This implies first of all the task to assess the importance of contact therapy within the scope of all therapeutic measures taken in case of uterine cervix carcinoma. Furthermore it was necessary to compare the importance of the different methods of contact therapy: conventional radium therapy as well as low dose rate and high dose rate afterloading techniques. As to surgical intervention, it is clear that only favorable stages can be taken into consideration for this treatment. It is shown by means of data taken from the Annual Report, Vol. 18, that a considerable number of patients with uterine cervix carcinoma I are irradiated even in hospitals whose field of activity lies preponderantly in surgery, and that by far most of the patients cured from uterine cervix cancer owe their recovery to contact therapy. The consideration of contact therapy methods show clearly that radium should no longer be used in clinical practice. Psychological doubts often hinder the decision if long-term or short-term afterloading therapy is to be applied. It is therefore shown that the very different forms of radium therapy with their chronological and spatial dose distribution were due to the characteristics of radium (e.g. little specific activity) or to other compelling features and that they were not based on radiobiological aspects. The radium dose values obtained by empirical research and the resulting spatial and chronological dose distribution are therefore not imperative. So it is not inevitable to choose the low dose rate afterloading method. On the contrary, the high dose rate technique with an adequate fractionation is very probably the method of choice. To sum up it can be said that contact therapy is still the most important therapeutic method in uterine cervix cancer. (orig.) [de

    The purpose of this study was to investigate the clinical findings, treatment, and outcome of patients with glassy cell carcinoma of cervix. We reviewed all cases of glassy cell carcinoma of the uterine cervix confirmed and treated at the Dongsan Medical Center, Keimyung University, between January 1993 and December 2005. There were 7 cases with histopathologically confirmed gassy cell carcinoma. A tumor was diagnosed as glassy cell carcinoma if over 50% of the tumor cell type displayed glassy cell features. Six patients with stage IB had radical hysterectomy and bilateral pelvic node dissection, and 2 of them received adjuvant external pelvic irradiation with concurrent chemotherapy. Remaining one patient with stage IIA had curative concurrent chemoradiotherapy with external pelvic irradiation and brachytherapy. There were 7 patients diagnosed as glassy cell carcinoma among the 3,745 (0.2%) patients of carcinoma of uterine cervix. The mean age of 7 patients was 44 years with range of 35 to 53 years of age. The most frequent symptom was vaginal bleeding (86%). By the punch biopsy undertaken before treatment of 7 cases, 2 only cases could diagnose as glassy cell carcinoma of uterine cervix, but remaining of them confirmed by surgical pathological examination. The mean follow up duration was 73 months with range of 13 to 150 months. All 7 patients were alive without disease after treatment. Glassy cell carcinoma of the uterine cervix is a distinct clinicopathologic entity that demonstrates an aggressive biologic behavior. However for early-stage disease, we may have more favorable clinical outcome with radical surgery followed by chemoradiotherapy

However, the mechanisms of the oncogenesis and development process of cervix carcinoma are not yet fully understood. Long non-coding RNAs (lncRNAs) have been proved to play key roles in various biological processes, especially development of cancer. The function and mechanism of lncRNAs on cervix carcinoma is still rarely reported. We selected 3 cervix cancer and normal cervix tissues separately, then performed lncRNA microarray to detect the differentially expressed lncRNAs. Subsequently, we explored the potential function of these dysregulated lncRNAs through online bioinformatics databases. Finally, quantity real-time PCR was carried out to confirm the expression levels of these dysregulated lncRNAs in cervix cancer and normal tissues. We uncovered the profiles of differentially expressed lncRNAs between normal and cervix carcinoma tissues by using the microarray techniques, and found 1622 upregulated and 3026 downregulated lncRNAs (fold-change>2.0) in cervix carcinoma compared to the normal cervical tissue. Furthermore, we found HOXA11-AS might participate in cervix carcinogenesis by regulating HOXA11, which is involved in regulating biological processes of cervix cancer. This study afforded expression profiles of lncRNAs between cervix carcinoma tissue and normal cervical tissue, which could provide database for further research about the function and mechanism of key-lncRNAs in cervix carcinoma, and might be helpful to explore potential diagnosis factors and therapeutic targets for cervix carcinoma.

    Purpose: To evaluate magnetic resonance imaging (MRI) in the planning of radiation therapy for patients with carcinoma of the cervix treated with a four-field technique. Methods and Materials: Between May 1994 and February 1995, 18 patients with carcinoma of the cervix were entered in the study (1 T1 N-; 2 T2a N-; 1 T2b NO; 10 T2b N-; 2 T2b N+; 2 T3b N+). Node status was assessed by a laparoscopic pelvic lymphadenectomy. During the first step, all the patients were simulated with an isocentric four-field pelvic technique. In one group (11 patients) simulation was done based on clinical examination, computed tomography (CT), and standard guidelines. In the second group (seven patients) simulation was based on clinical examination, CT, and with the help of diagnostic MRI, which was available at that time. During the second step, MRI in treatment position with skin markings of the isocenter of the radiation fields was then performed in every patient. During the third step, in each patient, the simulated radiation fields were correlated with the MRI defined target volume by superimposing them on midsagittal and midcoronal MR images. The adequacy of the margins was arbitrarly defined as 1 cm around the MRI defined target volume (tumor of the cervix and its extension, and uterus). Results: In the first group (11 patients), MRI in treatment position led to a change in 7 patients: six inadequate margins in the lateral fields and one in the anterior and lateral field. In almost all the cases, the adjustments were of an increase of 10 mm, equally matched between the anterior and posterior borders of the lateral fields. In the second group (seven patients), MRI in treatment position has led to a change in lateral fields in five patients. The mean adjustment was 10 mm: four increases (two anterior border, one posterior border, one anterior and posterior border), and one decrease of the posterior border. In the two groups, modifications of the anterior border of the lateral

    Body weight, ovary and uterus weight, the nature of estral cycles, and hypothalamus dopamine and noradrenaline levels and plasma testosterone levels were studied in female GC rats, bred for increased catatonic reactivity, at different stages of the estral cycle (estrus, proestrus). The outbred Wistar strain served as controls. On the background of decreased body weight, GC females showed impairments to the morphological cyclical changes in the ovaries and uterus, with a reduction in ovary weight in diestrus (p rats showed higher levels of these monoamines in estrus and lower levels in diestrus. Plasma testosterone levels in female GC rats were higher in diestrus than in estrus and in Wistar rats.

    Full Text Available Placenta membranacea is a rare anomaly characterized by failure of villous atrophy during early gestation, and 30% of cases involve some form of placental adherence. Placenta percreta is infrequent, but life-threatening condition. Antenatal diagnosis of these placental anomalies is very difficult, but essential for reduction of the number and extent of possible complications. A 19-year-old primigravida was referred to us with 31- week pregnancy complicated by preeclampsia. Upon admission, ultrasound scan revealed eutrophic fetus in breech presentation, without any signs of retroplacental clot. At laparotomy, hemoperitoneum without any trophoblastic tissue emerging to the peritoneal cavity was found and placental abruption with uteroplacental apoplexy was suspected. In addition, unicervical symmetric bicornuate uterus with pregnancy in the left uterine horn was found. The lower segment uterine section was performed and 1800 grams live baby was delivered. Delivery of the placenta was unusually difficult. It was very large and densely adherent to the posterior uterine wall, which appeared to be composed of serosa in that area only. After removal of placenta, the hemorrhage could not be controlled, and resection of the left uterine horn was performed. Placenta accreta, increta and percreta ought to be considered in all cases of uterine anomalies in pregnancy and in cases of prenatal diagnosis of placenta membranacea.

    During a period 1984-1991, 18 patients were diagnosed as developing osteonecrosis after radiation therapy for uterine cervical cancer. The patients had Stage I-III. Acute pain occurred in the lumbar spine, pelvis, and/or limbs. There was no correlation between osteonecrosis and either clinical staging or the associated surgery. The most common site of osteonecrosis was lumbar spine (n=13), followed by sacroiliacal joint and head and neck of femur (5 each) and pubic bone (3). The duration from radiation therapy to occurrence of osteonecrosis varied from one to 8 years: the latency period tended to be longer for younger patients. There was correlation between radiation doses and site of osteonecrosis: 60 Gy caused more extensive osteonecrosis, involving the pelvis and head of femur, although 40 Gy confined it to the lumbo-sacral region. Osteonecrosis was sometimes difficult to diagnose: needle biopsy, in addition to imaging modalities, was necessary in 4 patients. It is recommended that patients with uterus cervical cancer treated with radiation be followed up carefully. (N.K.).

    Since 10 years, the combination of chemoradiotherapy has become a standard of treatment of the advanced localized cervical cancer. Two systematic reviews of the literature (including the results of the different clinical trials) have already been published. The aim of this article is to present the results of the recent meta-analysis based on individual patient data and to discuss the perspectives. This meta-analysis was rigorously designed: trials selected had the same control arm with the same radiotherapy without concomitant chemotherapy, the definition of the primary outcome (overall survival) was homogeneous and analysis was made in intent to treat. The results confirm the advantage in overall survival in favor of the chemoradiotherapy with an absolute 5-year overall survival benefit of 6% (60-66%) and 8% of 5-year disease-free survival (50-58%). Interestingly, even if cisplatin seems to be the most active drug, a significant advantage is also observed with no platinum chemotherapy. A polychemotherapy is not more active than a mono chemotherapy and there was a suggestion of a difference in the size of the survival benefit with tumor stage. Larger benefits were seen for the few trials in which additional chemotherapy was administered after chemoradiotherapy, but results have to be confirmed by other clinical trials. Late toxicity was not well evaluated and a long-term follow-up of the patients is important to assess the real incidence of long-term side effects of the chemoradiotherapy and the impact on quality of life. New strategies combining new chemotherapy protocols or targeted therapy with radiation are promising but have to be evaluated in comparative clinical trials before use in routine. (authors)

    Full Text Available The presence of cervicovaginal agenesis with unicornuate uterus is a very rare mullerian anomaly. Its true incidence is still unknown. The presence of functioning unicornuate uterus poses a great challenge for a gynecologist because a successful repair could restore normal menses and may preserve a patient′s fertility. Hence, we report a case of 16-year-old unmarried female who presented with chief complaints of primary amenorrhea with cyclical lower abdominal pain. On clinical and radiological evaluation, she was diagnosed with complete cervicovaginal agenesis with right unicornuate uterus (hematometra and hematosalpinx. She underwent vaginoplasty (McIndoes method along with uterovaginal anastomosis by neocervix formation, in order to preserve her uterus. On follow-up, her vagina was completely healed, and she was menstruating normally.

    Physical simulation systems are commonly used in training of midwifery and obstetrics students, but none of these systems offers a dynamic compliance aspect that would make them more truly representative of cervix ripening. In this study, we introduce a unique soft robot phantom that simulates the cervix softening during the latent labor phase of birth. This proof-of-concept robotic phantom can be dilated by 1 cm and effaced by 35% through the application of a Foley catheter-like loading mechanism. Furthermore, psychophysics trials demonstrate how untrained subjects can identify hard and soft states of the phantom with specificities of 91% and 87%, respectively. Both results indicated the appropriateness for application of this soft robot technology to birth training simulators.

    Full Text Available Cancer is an important health problem due to the high morbidity and mortality which it produces. The first cause of women death between 30 and 44 years old in Cuba is cervix carcinoma. This is a case of a 39 year old woman who presented to the secondary health care level with a stage IV cervix tumor where it was diagnosed, it simulated an anaemic syndrome due to another cause. The histological and imaging studies were concluding. Primary prevention of this kind cancer by means of health education and searching in the risk population are paramount. The program of early detection still has difficulties. The presentation of this case is aimed at teaching so as documentary exposition for professionals of primary health care attention, gyneco-obstetricians, internists and any other clinical specialty derived.

  6. Cervix carcinomas: place of intensity-modulated radiotherapy

    2009-01-01

    While indications of modulated intensity radiation therapy (I.M.R.T.) are perfectly defined in head and neck and prostate cancer patients, this technique remains under evaluation for gynecologic tumours. The implementation of conformal three dimensional radiotherapy in the late 1990 has been the first important step for optimisation of treatment of cervix carcinomas, as it permitted a better target coverage with a significant reduction of the bladder dose. However, this technique often leads to an irradiation of a larger volume of rectum in locally advanced stages and could only spare a limited amount of intestine. I.R.M.T. is one of the optimisation methods potentially efficient for a better sparing of digestive tract during irradiation of cervix carcinomas. The aim of this literature review is to provide the arguments supporting this hypothesis, and to define the place of this technique for dose escalation. (authors)

    Full Text Available Abstract Introduction Peripheral primitive neuroectodermal tumor of the cervix uteri is extremely rare. Between 1987 and 2010, there were only nine cases reported in the English literature, with considerably different management policies. Case presentation A 45-year-old Iranian woman presented to our facility with a primitive neuroectodermal tumor of the cervix uteri. Her clinical stage IB2 tumor was treated successfully with chemotherapy. Our patient underwent radical hysterectomy. There was no trace of the tumor after four years of follow-up. Conclusions According to current knowledge, primitive neuroectodermal tumors belong to the Ewing's sarcoma family, and the improvement of treatment outcome in our patient was due to dose-intensive neoadjuvant chemotherapy, surgery and consolidation chemotherapy in accordance with the protocol for bony Ewing's sarcoma.

    Lymphoma of the cervix is a rare disease. About 1.0% to 1.5% of extranodal lymphomas originates in the female genital tract. The clinical presentation of this condition is nonspecific and magnetic resonance imaging is important for diagnostic elucidation. The present report describes the case of a 80-year-old patient with lumbar pain, whose magnetic resonance imaging showed a large uterine mass. The final diagnosis was lymphoma. (author)

    Visual inspection followed by biopsy is the standard procedure for cancer diagnosis. Due to invasive nature of the current diagnostic methods, patients are often non-compliant. Hence, it is necessary to explore less invasive and rapid methods for early detection. Exfoliative cytology is a simple, rapid, and less invasive technique. It is thus well accepted by patients and is suitable for routine applications in population screening programs. Raman spectroscopy (RS) has been increasingly explored for disease diagnosis in the recent past. In vivo RS has previously shown promise in management of both oral and cervix cancers. In vivo applications require on-site instrumentation and stringent experimental conditions. Hence, RS of less invasive samples like exfoliated cells has been explored, as this facilitates collection at multiple screening centers followed by analysis at a centralized facility. In the present study, efficacy of Raman spectroscopy in classification of 15 normal and 29 abnormal oral exfoliated cells specimens and 28 normal and 38 abnormal cervix specimens were explored. Spectra were acquired by Raman microprobe (HE 785, Horiba-Jobin-Yvon, France) from several areas to span the pellet. Spectral acquisition parameters were: microscopic objective: 40X, power: 40 mW, acquisition time: 15 s and average: 3. PCA and PC-LDA of pre-processed spectra was carried out on a 4-model system of normal and tumor of both cervix and oral specimens. Leave-one-out-cross-validation findings indicate 73 % correct classification. Findings suggest RS of exfoliated cells may serve as a patient-friendly, non-invasive, rapid and objective method for management of cervix and oral cancers.

    The pregnant uterus was found to exert pressure upon the lumbar region with a maximum over the midline of the lordosis and diminishing laterally. Those parts of the arterial system formed by the aorta and its dorsal branches and displaceable at autopsy, were accordingly dislodged by the uterus, whereas the fixed parts were compressed. The pressure effects extended cranially during pregnancy. Symptoms of compression can be relieved by avoiding supine and prone positions.

    Hemangioma is the most common soft tissue tumor in the body. Though it may occur anywhere in the body, hemangioma of the uterus is a very rare tumor. Hemangioma is almost asymptomatic, but it is sometimes clinically important because it can cause massive hemorrhage and this is a life-threatening condition. We report here on the magnetic resonance imaging and pathologic findings of cavernous hemangioma of the uterus in a 32-year-woman with menorrhagia.

    Full Text Available Adenocarcinoma in situ is one of the premalignant lesions of the cervix and its incidence is believed to be increasing while the pathogenesis of the disease is not clearly understood. Management of Adenocarcinoma in situ (AIS unlike carcinoma in situ (CIS has not been clearly described in the current literature. Here we describe conservative management and serial colposcopy of two pregnant women with adenocarcinoma in situ of the cervix. Both of the cases were diagnosed initially with abnormal Pap smears and were confirmed by colposcopic directed biopsy. None of the patients agreed with any invasive procedure during pregnancy and both of them were followed with serial colposcopy. None of the lesions showed any evidence of progression. All cases underwent cold knife cone biopsies in their postpartum period. Hysterectomy as the final treatment has been done in both cases with no evidence of progression of the disease during pregnancy. We concluded that adenocarcinoma in situ of the cervix during pregnancy could be managed conservatively with definite treatment postponed till after delivery.

    Cancer of cervix is the second most common cancer worldwide among women. Several treatments related protocols of radiotherapy have been followed over few decades in its treatment for evaluating the response. These physical doses varying on the basics of fractionation size, dose rate and total dose needed to be indicated as biological effective dose (BED) to rationalize these treatments. The curative potential of radiation therapy in the management of carcinoma of the cervix is greatly enhanced by the use of intracavitary brachytherapy. Successful brachytherapy requires the high radiation dose to be delivered to the tumor where as minimum radiation dose reach to surrounding normal tissue. Present study is aimed to evaluate biologically effective dose in patients receiving high dose-rate brachytherapy plus external beam radiotherapy based on tumor cell proliferation values in cancer of the cervix patients. The study includes 30 patients' data as a retrospective analysis. In addition determine extent of a dose-response relationship existing between the biological effective dose at Point A and the bladder and rectum and the clinical outcomes

    In addition to numerical changes of lymphocytes and monocytes of patients with cancer of the cervix uteri and patients treated with radiation therapy for cancer of the cervix uteri, PHA, PPD, and intractaneous reaction of Candida antigen of them were discussed. The subjects were 31 cases of normal group, 158 cases of cancer of the cervix uteri, and 35 cases which received radiation therapy with a dose of 6,000 R. The number of leukocyte significantly decreased after irradiation with 1,000 R as compared with that before irradiation, but marked decrease was not recognized irrespective of an increase of irradiation dose thereafter. The ratio of lymphocyte to leukocyte significantly decrease after irradiation with 2,000 R, and there were many cases with the ratio of under 20%. The number of lymphocyte significantly decreases after irradiation with 1,000 R, but the decrease was not recognized after irradiation with 2,000 R. The ratio of monocyte to leukocyte significantly increased in the irradiated group with 2,000 R and 3,000 R. With respect to intracutaneous reaction, a lowering of the reaction was recognized in general, and the reaction to non-specific antigen remained strongly. (Tsunoda, M.)

    Full Text Available BACKGROUND Disease of the cervix is a common clinical condition in females, worldwide and especially in a developing country like India. The study was undertaken in Guwahati Medical College to see the age related changes in the morphology of the cervix. AIM The study was done to observe the age related changes in the cervix and compare the same with the different studies done by the previous workers around the world so as to help clinicians to diagnose the pathologies of this part of the female reproductive system better. MATERIALS AND METHOD The specimens were divided into three groups viz. pre-reproductive, reproductive and post-menopausal. Twenty specimens were collected of each group. The results were statistically analysed and ‘t’ test was employed to find out the significant difference between the mean value. SUMMARY A study of the 60 specimens collected were done to find the morphological parameters of each group viz. pre-reproductive, reproductive and post-menopausal and the findings of each group were compared to one another and were related to the finding of previous workers. CONCLUSION The study showed that there were certain differences in the morphology of the three groups and these differences tallied with that of the previous workers.

    The many-year experience with the treatment of the cervix uteri cancer has indicated that a combined method in case of the appropriate indications provides for high and persistant delayed results. The five-year recovery of patients at all stages was noted in 78.7% (1 stage-87.3%; 2 stage-71.6 %, 3 stage-41.7%). Improvement of therapeutic and diagnostic methods, strict adherence to the principles of a differential approach to selecting the type of therapy enabled increasing the per cent of a five-year cure from 68.9%' (1945-46) to 91.8% in 1965-69. The clinical features of microinvasive cervix uteri canner (stage 1a) made it possible to reduce the extent of the treatment applied on account of excluding a radiation component and lessening the extent of surgical intervention. A five-year cure by the surgical method in patients with cancer of stage 1a made up 97%. The results of the combined therapy in patients cervix uteri with stage 1b within the same period yielded 94%

    The addition of screens in the vaginal source holders of a cervix applicator for intracavitary brachytherapy reduces the dose to rectum and bladder and therefore diminishes the number of rectal and vesical complications. Shielding properties of tungsten rectal and bladder screens of a Selectron cervix applicator, loaded with spherical cesium sources, were determined for verification of dose calculations. The accuracy of the new screen correction algorithm of the Selectron Planning System was assessed by comparing measured and calculated dose rates and was found to be better than +-4%. The correction algorithm provides a method to analyse the efficacy of screens in the ovoids for various segment geometries and orientations without extensive phantom measurements. Isotransmission and isodose calculations were made for a typical clinical applicator set-up and source distribution. The dose reduction to rectum and bladder, near the bottom and top of the ovoids was analysed in detail. Shielding properties of a Selectron cervix applicator, provided with screens, were compared with those of some Fletcher-type applicators. Significant differences between the transmission ratios and shielded areas of the screens of both systems near rectum and bladder were observed. (Auth.)

    Full Text Available We aimed to perform a chemical analysis of both Alibernet red wine and an alcohol-free Alibernet red wine extract (AWE and to investigate the effects of AWE on nitric oxide and reactive oxygen species production as well as blood pressure development in normotensive Wistar Kyoto (WKY and spontaneously hypertensive rats (SHRs. Total antioxidant capacity together with total phenolic and selected mineral content was measured in wine and AWE. Young 6-week-old male WKY and SHR were treated with AWE (24,2 mg/kg/day for 3 weeks. Total NOS and SOD activities, eNOS and SOD1 protein expressions, and superoxide production were determined in the tissues. Both antioxidant capacity and phenolic content were significantly higher in AWE compared to wine. The AWE increased NOS activity in the left ventricle, aorta, and kidney of SHR, while it did not change NOS activity in WKY rats. Similarly, increased SOD activity in the plasma and left ventricle was observed in SHR only. There were no changes in eNOS and SOD1 expressions. In conclusion, phenolics and minerals included in AWE may contribute directly to increased NOS and SOD activities of SHR. Nevertheless, 3 weeks of AWE treatment failed to affect blood pressure of SHR.

    Background: Leiomyoma, myoma, leiomyoma or fibroids are synonymous terms. They may be present in as many as 1 in 5 women over age 35 years. If pregnancy is associated with fibroids, it leads to multiple complications. Objectives of this study were to evaluate the maternal and foetal outcome in women having pregnancy with fibroids in uterus and the complications associated with fibroids during the pregnancy. Methods: This descriptive study was conducted in the Department of Obstetrics and Gynaecology, Ayub Teaching Hospital Abbottabad from March 2009 to March 2010. Data were collected on proforma regarding demographic variables, obstetrical history, mode of delivery, maternal outcome, maternal complications, and foetal outcome. Mean and standard deviation was calculated for age, period of gestation, and obstetrical history. Frequency and percentages was calculated for booking status, maternal outcome, maternal complications and foetal outcome. Results: Thirty patients were included in this study who had pregnancy with fibroid. Normal delivery was achieved in 14 (46.66%) patients. Eight (26.67%) patients had caesarean section and eight (26.67%) had miscarriages. Seven (23.33%) patients had no complications while 8 (26.67%) had miscarriages, 8 (26.67%) had postpartum haemorrhage, 10 (33.33%) had preterm delivery, and 3 patients had ante-partum haemorrhage. Two (10%) patients had premature rupture off membranes and 1 patient (3.33%) had pain abdomen and technical difficulty during caesarean section. There were 12 (40%) healthy babies. Five (16.67%) babies delivered with morbidity but recovered. There were 4 (13.33%) intrauterine deaths and one early neonatal death. Conclusion: Fibroid in pregnancy, especially multiple intramural fibroids and fibroids larger than 10 Cm, cause miscarriage and preterm labour. (author)

    Full Text Available Uterine angioleiomyoma is rare. A 40-year-old nulliparous woman presented with heavy menstrual bleeding (HMB for the past 2 years and mass per abdomen with severe dysmenorrhea for three cycles. She had received 8 units of packed cell transfusion outside. Clinical examination revealed a huge 32-week-sized abdominopelvic mass with irregular margins. Ultrasonography (USG of the abdomen and pelvis showed a large solid cystic mass on the right side of the abdomen with a well-defined hypoechoeic rounded lesion of size 5.7 cm × 5.0 cm, in the right lobe of the liver, with ovaries not being imaged separately. On color Doppler USG, there was moderate vascularity throughout. A provisional diagnosis of malignant ovarian tumor with hepatic metastasis was made. Her hemoglobin was 5.7 g/dl, and she had repeated episodes of HMB upon admission. She was transfused with 5 units of packed cells. Computed tomography (CT showed a large fundal subserosal uterine fibroid on the right side, with a solid ovarian tumor measuring 5.0 cm × 4.5 cm on the left side, with ascitis, right-sided hydronephrosis, and a well-defined hypoechoeic lesion in the right lobe of the liver, suggestive of hepatic hemangioma. Tumor markers were within normal limits. In view of discrepancy in clinical findings, ultrasound, and CT report, CT-guided biopsy of the huge mass was done which revealed leiomyoma, with no evidence of mitosis, pleomorphism, or malignancy. Laparotomy with total abdominal hysterectomy and bilateral salpingo-oophorectomy was done. Histopathology revealed an angioleiomyoma uterus. At 1-year follow-up, she was asymptomatic, and the liver mass was stable.

    Purpose: To evaluate the impact of inadequate margins on pelvic control using the conventional four-field pelvic portals without computed tomography (CT)-treatment planning. Methods and Materials: Between 1986 and 1991, 34 patients with invasive cancer of the cervix were eligible for outcome study of conventional four-field radiation therapy (10 Stage I, 16 Stage II, 8 Stage III). The eligibility for this study includes four-field pelvic technique, definitive radiation therapy, and diagnostic CT scan of the pelvis. For this study, an inadequate margin is arbitrarily defined as ≤ 1.0 cm of normal tissue around the CT-defined tumor volume. Results: All 34 patients had adequate margins for anterio-posterior/posterio-anterior portals. However, 19 patients had an inadequate margin at the posterior border (S2-S3 interspace) and/or custom-shaped rectal block for lateral pelvic portals. Two patients had inadequate margins at the anterior border (level of symphysis pubis) due to an enlarged uterus. With a median follow-up of 36 months, pelvic control for adequate margins and inadequate margins was 100% and 71% for Stage IB disease and 88% and 50% for Stage IIB disease, respectively. However, pelvic control for Stage IIIB disease was 50% for both groups. There was no difference in total dose to point A or point B between the two groups. Conclusion: Our preliminary data show higher local failure in patients with an inadequate margin. For four-field pelvic radiation therapy, we strongly recommend CT-treatment planning. Otherwise, anterio-posterior/posterio-anterior pelvic therapy is the most reliable treatment for cancer of the uterine cervix

    A case of polypoid endocervical adenomyoma in the uterine cervix was encountered in a 56-year-old woman. A well-circumscribed polypoid tumour was observed protruding from the uterine cervix. Based on the findings of MR imaging, the patient was assumed to have an adenoma malignum in the uterine cervix. The tumour was composed of a mixture of endocervical type proliferating glands and fascicles of smooth muscle. No distinct nuclear anaplasia, architectural abnormality, or evidence of destructive stromal invasion was observed. In our case, the tumour was a well-circumscribed polypoid lesion, with no cytologic abnormality, thus suggesting polypoid endocervical adenomyoma. The result of ancillary diagnostic modalities should be interpreted with caution and combined with gross and light microscopic findings.

    Investigations of sexual consciousness and sexual dysfunction after radiotherapy for cancer of the cervix uteri were performed on patients of middle and old ages by questionnaires and questionning by doctors, and the following results were obtained. 1. Before radiotherapy, sexual activity was most prominent in their twenties and thirties. However, patients who were in fifties when this study was performed had most active sexual lives during the ages from 35 to 50 years. 2. Frequencies of sexual intercourse decreased markedly just before radiotherapy, and many patients received radiotherapy when sexual activity fell. 3. 32% of the patients have not experienced sexual intercourse after radiotherapy. 4. Decreases in the sex urge, sexuality, vaginal dicharge, and frequency of sexual intercourse after radiotherapy were recognized in 77%, 77%, 70%, and 93% respectively. 5. Patients who became unwilling to maintain sexual lives after radiotherapy because of fear about recurrence or aggravation of cancer were 38% by questionnaires and 49% by questionning by doctors. 6. Pains on sexual intercourse were found in 69% by questionnaires and 49% by questionning by doctors. Most pains occurred at pennis insertion and was thought to be due to atrophy and inflammation of vagina and external genitalia in most cases. 7. Both vaginal damages and sexual dysfunction in patients with radiotherapy following surgery for cancer of the cervix uteri, in patients with radiotherapy alone for cancer of the cervix uteri, and in patients with radiotherapy following surgery for cancer of the ovary and corpus uteri were marked, modest and mild, respectively. 8. Vaginal damage score was higher in patients treated more than 5 years before than those less than 2 years ago, but there were no differences in sexual dysfunction score between both groups.

    The course and outcome of pregnancy is closely correlated to change of biomechanical properties of the uterine cervix. The aim of this study was to build a non-linear, fiber reinforced mechanical model of the cervix for estimation of mechanical characteristics of the cervix in early- and term-pregnant women based on recordings of in vivo pressure and diameter by means of the Functional Luminal Imaging Probe (FLIP) technology. Five early- and six term-pregnant women were examined with a FLIP probe. The bag on the probe was inserted into the cervical canal for concomitant measurement of diameters at 16 serial locations along the canal and the bag pressure. The bag was inflated to a maximum volume of 50 ml. A three-fiber-families model including isotropic elastin-dominated matrix and anisotropic collagen was introduced to describe the mechanical behavior of the cervical canal. The unknown geometric and mechanical parameters were calculated on the basis of the mid-cervical diameters and the intraluminal pressures during the inflation. The wall thickness in the unloaded state (zero pressure applied) and mechanical properties of the matrix material (c) and collagens (c1, c2) were estimated with good fits of the calculated intraluminal pressures to the FLIP recordings during the cervical canal distension. No significant difference in the wall thickness was found between the early- and term-pregnant women (10.3 ± 0.8mm vs. 11.7 ± 2.2mm, p=0.30). The cervical matrix material and the collagen in the early-pregnant women were much stiffer than that in the term-pregnant women (pcervix wall were remodeled during pregnancy. The mechanical model can be applied to other tubular visceral organs where concomitant measures of pressure and diameter can be obtained for better understanding diseases and their evolution or treatment.

    Yang, Mi Gyoung

    1994-01-01

    Purpose: The role of radiotherapy in the management of patients with locoregional recurrent cervix cancer after radical surgery were retrospectively analyzed. Methods and materials: Twenty-eight patients treated with radiotherapy for locoregional recurrence after primary surgery for carcinoma of the cervix between 1989 and 1993 were analyzed. The median follow-up of survivors was 15 months (ranged 7-43 months). Eight patients had their disease confined to the vagina and 19 patients(68%) had pelvic mass as part of their locoregional recurrent disease. Within 24 months after the initial surgery, 82% of recurrences manifested themselves. All patients had whole pelvic irradiation with or without intracavitary radiotherapy(ICR). Results: Complete response(CR) was achieved in 18 patients(64%). Five of eighteen patients(28%) with initial CR developed second locoregional recurrence. Response to radiotherapy correlated strongly with tumor volume, site of recurrence and total radiation dose. The overall 2 year survival rate was 43% and the disease free survival was 31%. Survival rate was significantly influenced by the factors of interval from operation to recurrence, size and site of recurrent tumor, radiation dose, response of radiotherapy, lymph node status as initial presentation. The principal cause of death was lung metastasis(36%). Conclusion: Radiotherapy is an excellent modality for control of locoregional recurrent cervix cancer. To improve local control and survival rate, whole pelvic external radiotherapy in addition to ICR with more than 75.0Gy at the depth of 1.0cm from vaginal mucosa is needed and frequent follow up and early detection of recurrence is suggested as well

    1995-01-01

    Purpose: Radiation therapy alone for adenocarcinoma of the cervix is currently evaluated by the accumulation of long-term results because of the low incidence of this disease. Materials and Methods: Fifty-eight patients with adenocarcinoma of the cervix treated with radiation therapy alone between 1961 and 1988 were studied. The radiation therapy consisted of a combination of intracavitary and external pelvis irradiation. Intracavitary treatment was performed with low dose rate and/or high dose rate sources. Results: The 5-year survival rates for Stages I, II, III, and IV were 85.7%, 66.7%, 32.3%, and 9.1%, respectively, and the 10-year survival rates were 85.7%, 60.0%, 27.6%, and 9.1%, respectively. The local control rate with high dose rate treatment was 45.5%, significantly lower than 85.7% and 72.7% with low and mixed dose rate treatments, respectively. Five-year survival and local control rates by tumor volume were 68.6% and 80.0% for small tumors, 63.6% and 66.0% for medium tumors, and 14.4% and 18.2% for large tumors, respectively. The survival rate and local control rate for large tumors were significantly lower than those for small and medium tumors. Multiple regression analysis indicated that stage and tumor volume were independent variables for survival and local control, respectively. Isoeffective dose expressed by time dose fractionation (TDF) was not associated with local control. Radiation complications developed in 10 patients (17.2%), most of which were of moderate degree. Conclusion: Radiation therapy alone for adenocarcinoma of the cervix was regarded to be an effective treatment, comparable to combination therapy of surgery and radiation therapy

    To determine whether women with sonographically identified uterine fibroids are at higher risk for a short cervix. This retrospective cohort study evaluated all women with singleton gestations who had a routine second-trimester ultrasound at 17-23 weeks gestational age from 2010 to 2013. When fibroids were noted, their presence, number, location and size were recorded. Exclusion criteria included a history of cervical conization or loop electrosurgical excision procedure (LEEP), uterine anomalies, maternal age greater than 40 years, and a previously placed cerclage. The primary variable of interest was short cervix (cervix was increased in women with fibroids (OR 2.29, 95% CI: 1.40, 3.74). The number of fibroids did not affect the frequency of short cervix. Fibroids were significantly associated with preterm delivery (cervix. Fibroids are also associated with several adverse obstetric and neonatal outcomes.

    Forty MR imaging examinations in 38 patients with newly diagnosed or recurrent squamous cell carcinoma of the cervix were retrospectively evaluated and compared with clinical and surgical findings for staging. There was poor correlation between loss of fat planes and extension of tumor into the rectum or bladder, and it was impossible to differentiate bladder edema from direct invasion. MR imaging underestimated parametrial and pelvic sidewall extension when compared with physical exam under anesthesia. MR imaging was useful in the direct demonstration of a cervical mass and in detecting enlarged pelvic nodes

    Full Text Available Carcinoma of cervix is the most common cancer in developing countries. Majority of them present in locally advanced stages. A 36-year-old lady presented with bleeding and white discharge per vagina since four months, vomiting and reduced urine output since two weeks. Patient had an exophytic cervical growth. Investigation revealed elevated serum creatinine. Patient received single fraction radiation and underwent percutaneous nephrostomy. At one month follow-up, serum creatinine returned to almost normal level. Patient underwent bilateral ante grade stenting and completed concurrent chemoradiotherapy. In selected subsets of patients, aggressive management offered longer palliation and good quality of life.

    Following irradiation of a carcinoma of the cervix, the vagina is frequently narrowed or sometimes obliterated. This article considers the sexual functioning of women following such treatment. They noticed changes in their emotions and felt alterations in their function as a woman. They were less happy with cohabitation and found it more difficult to experience an orgasm. Their frequency of lovemaking diminished as did the occurrence of sexual dreams. A treatment scheme for helping such women with their sexual problems is outlined. (C.F.)

    Vascular complications after this treatment are rare. Artery stenosis or occlusions, more often iliac, are well recognized complications of postoperative radiotherapy. These segmental lesions, sometimes, are pathological lesions similar to arteriosclerotic changes. These lesions may be corrected later on after the treatment of carcinoma of the cervix. The venous complications often present later and tall within the context of post thrombotic syndrome. Conservative treatment is indicated alone. A well recognized complication, lymphedema is usually mild; a superimposed iliofemoral thrombophlebitis often may be suspected [fr

    Whereas the local effect of radiotherapy in the postoperative treatment of uterine cervix cancer developing lymphogenic metastases may be regarded as clearly demonstrated, there is no evidence of its effect on the survival of patients. A definite answer to this question is only possible on the basis of prospective studies. In primary radiotherapy, more importance than in former days is given to percutaneous irradiation which allows a more homogeneous dose to the small pelvis. According to the present state of knowledge it is not justified to do without contact therapy except in cases of a very advanced disease. (orig.) [de

    Results: The median age of the patients in this group was 47.5 years, with a range of 30–80 years. The major histological type of carcinoma among 40 cases is squamous cell carcinoma (SCC (in 90% of cases, and 10% had adenocarcinoma. Pathological staging of the carcinoma cervix showed stage Ib, IIa, IIb, and IVa (35%, 20%, 40%, and 5%. Tumor volume estimated on pathological specimens of 40 cases ranged from 230 cumm to 49,760 cumm with a mean of 14,844 cumm. 12 (30% cases had tumor volume more than 15,000 cumm, 12 (30% cases had tumor volume <5000 cumm and 16 (40% cases had tumor volume between 5000 and 15,000 cumm. 17% of the tumors with tumor volume <5000 cumm showed lymph node metastases, whereas 67% (out of 12cases of cases with tumor volume more than 15,000 cumm showed lymph node metastases. 67% of the tumors with tumor volume <5000 cumm showed 0/4 organs involvement, whereas all cases with tumor volume more than 15,000 cumm showed more than one organ involvement among vagina, uterus, parametrium or bladder/rectum. Fibronectin positivity was seen in 22 out of 44 cases (55%. Macrophages were seen surrounding the group of tumor cells by LN5 immunostaining. Conclusion: Tumor volume can be considered as an independent prognostic factor to assess the spread of the tumor. Cases with tumor volume <5000 cumm show low risk in terms of parametrial involvement and lymph node metastasis and those with tumor volume more than 15,000 cumm showed more organ spread. Fibronectin positivity carries some importance in low-risk cases. For macrophages, further detailed study needs to be carried out.

  6. Radiation injuries of the pelvis and proximal parts of the femur after irradiation of carcinoma of the cervix uteri

    Shimanovskaya, K.; Shiman, A.D.

    1983-01-01

    Data relating to 244 patients with carcinoma of the cervix uteri treated by intensive radiotherapy are given. Radiation injury of bone was diagnosed in 12 cases (4.9 +/- 1.4 percent). After x-ray therapy alone they were found in five of 59 patients treated (8.5 +/- 3.6 percent), and after γ-ray therapy in one of 171 cases (0.6 +/- 0.6 percent). The minimal focal dose of x-ray therapy causing radiation injury to bone was 5,000 rads. With an increase in dose, the frequency of injuries also increased. Radiation injury was found after γ-ray therapy with an absorbed dose of 7,000 rads. The radiological features of radiation injury of bones after irradiation of malignant tumors of the pelvis are increasing osteoporosis and the appearance of foci of sclerosis and osteolysis. Necrotic areas of various sizes may be formed. A fracture of the neck of the femur may be prevented in some cases by taking precautionary measures. Healing of an injured part depends on the size of the dose given. Large doses completely suppressed the reparative powers of the bone. Unlike changes that are traumatic in nature, radiation fractures of the pelvic bones and the proximal part of the femur have a mild clinical course; sometimes the patients continue to use the lower limb, simply complaining of pain that may vary in severity. Metastasization of tumors of the uterus to the pelvic bones is possible but infrequent. Metastases are usually associated with increasing pain

    Full Text Available A complete hydatidiform mole with a viable coexisting fetus (CMCF is a rare occurrence. Similarly, Mullerian anomalies such as a bicornuate uterus are uncommon variants of normal anatomy. We report a case of a 40-year-old female with a known bicornuate uterus presenting at 13 weeks gestation with vaginal bleeding. Ultrasound findings showed a healthy viable pregnancy in the right horn with complete molar pregnancy in the left horn. After extensive counseling, the patient desired conservative management, however, was unable to continue due to profuse vaginal bleeding. The patient underwent suction dilation and curettage under general anesthesia and evacuation of the uterine horns. Postoperatively, the patient was followed until serum beta-human chorionic gonadotropin (β-hCG level dropped to <5 mU. This is the first case of a CMCF reported in a bicornuate uterus, diagnosed with the use of ultrasound imaging.

    2013-01-01

    Full Text Available The isolated, complete, transverse vaginal septum is one of the most infrequent anomalies of the female genital tract, and when it coexists with a septate uterus, it is even rarer. This report describes a case of transverse vaginal septum with septate uterus. A 12-year-old girl sought medical assessment because of severe cyclic lower abdominal cramping and pelvic pain. Local examination revealed a blind vaginal pouch of 2 cm and on rectal examination a tender pelvic mass was noted. Radiological examination showed transverse vaginal septum in the lower vagina with bicornuate uterus. Surgical resection of the vaginal septum was done under laparoscopic guidance. Hysteroscopy revealed presence of uterine septum which was resected by a resectoscope. Post-operative dilatation of vagina was done to prevent restenosis. Laparoscopic guided abdominoperineal approach is better in such a case as multiple mullerian anomalies may coexist with each other.

  9. A Rare Case of Second Trimester Uterine Rupture in Unscarred Uterus

    Directory of Open Access Journals (Sweden)

    2017-11-01

    Full Text Available Second trimester uterine rupture is rare and presents with life threatening emergency. Few cases have been reported in literature. Most of the cases which have been reported are with the use of labor-induction agents in late termination of pregnancy. Others are involving any surgical procedures in placenta percreta or scarred uterus. The main contributory factors were scarred uterus and abnormal placentation. In this study, uterine rupture had occurred in unscarred uterus in non-laboring women in second trimester without any intervention which is very rare to found. The lack of index of high suspicion diverts attention to search for other non-gynecological causes. Our aim is to create awareness through this case study to avoid delay in diagnosis and timely management of such cases.

    invasive routes taken by EVT cells at the fetal-maternal interface that could displace them into the reproductive tract. Since the 1970s, investigators have attempted to recover trophoblast cells from the uterus or cervix for prenatal diagnostics. Trophoblast cells from Pap smears obtained at 5-20 weeks of gestation have been purified (>95% β-hCG positive) by immunomagnetic isolation with nanoparticles linked to anti-HLA-G (TRIC). The isolated cells contain the fetal genome, and have an EVT-like expression profile. Similar EVT-like cells appear in the lumen of uterine glands and can be observed entering the uterine cavity along the margins of the placenta, suggesting that they are the primary source of cervical trophoblast cells. Cells isolated by TRIC can be used to accurately genotype the embryo/fetus by targeted next-generation sequencing. Biomarker protein expression quantified in cervical trophoblast cells after TRIC correlates with subsequent pregnancy loss, pre-eclampsia and fetal growth restriction. A key remaining question is the degree to which EVT cells in the cervix might differ from those in the basal plate and placental bed. TRIC could one day provide a method of risk assessment for maternal and fetal disease, and reveal molecular pathways disrupted during the first trimester in EVT cells associated with placental maldevelopment. As perinatal interventions emerge for pregnancy disorders and inherited congenital disorders, TRIC could provide a key diagnostic tool for personalized precision medicine in obstetrics.

    The causal lesions by VPH in the cervix, are associated to cancer. Currently 56 different subtypes have been isolated, from which, the 16, 18, 31, 33, 35 and 39 are more frequently related with the cervical intraepithelial neoplasia; from here derives the importance of opportune treatment. The objective of this paper is to evaluate VPH of the cervix opportune treatment with cryosurgery. Seventy five patients were analyzed, from April 1988 to May 1990 with diagnosis of cervical VPH, by cytology, colposcopy and histopathology; in whom cryosurgery with double freezing technique, was practiced; and were evaluated ever six months, during two years with cytology and colposcopy. Whenever there was persistence or recurrence, cryosurgery was used again; doing this even three times, previously discarding intraepithelial cancer. Seventy seven per cent of the patients received only one session; 16% two, and 7% three. At the six months review, it was found that 92% of the cases were negative, and 8% with persistence; at 12 months, 89% negative and 11% with recurrences; at 18 months, 93% negative, 3% with persistence and 4% with recurrence; at 24 months, 96% negative and 4% with recurrence. It is concluded that cryosurgery is efficacious in the treatment of these lesions, easy to use, well tolerated, with minimal side effects, it does not require anesthesia and is of a low cost.

    To estimate determinants of and outcomes associated with activity restriction among women with a short cervix. This was a secondary analysis of a randomized trial of 17-α hydroxyprogesterone caproate for prevention of preterm birth among nulliparous women with singleton gestations and cervices less than 30 mm by midtrimester ultrasonography. Women were asked weekly whether they had been placed on pelvic, work, or nonwork rest. "Any activity restriction" was defined as being placed on any type of rest. Factors associated with any activity restriction were determined and the association between preterm birth and activity restriction was estimated with multivariable logistic regression. Of the 657 women in the trial, 646 (98%) responded to questions regarding activity restriction. Two hundred fifty-two (39.0%) were placed on any activity restriction at a median of 23.9 weeks (interquartile range 22.6-27.9 weeks). Women on activity restriction were older, more likely to have private insurance, less likely to be Hispanic, had a shorter cervical length, and were more likely to have funneling and intra-amniotic debris. Preterm birth at less than 37 weeks of gestation was more common among women placed on activity restriction (37% compared with 17%, Prestriction (adjusted odds ratio 2.37, 95% confidence interval 1.60-3.53). Results were similar for preterm birth at less than 34 weeks of gestation. Activity restriction did not reduce the rate of preterm birth in asymptomatic nulliparous women with a short cervix.

    Since its introduction in clinical practice in the 1990 s, positron emission tomography (PET), usually with 18 F-fluoro-2-deoxy-D-glucose ( 18 F-F.D.G.), has become an important imaging modality in patients with cancer. For cervix carcinoma, F.D.G.-PET is significantly more accurate than computed tomography (CT) and is recommended for loco-regional lymph node and extra pelvic staging. The metabolic dimension of the technique provides additional prognostic information. Ongoing studies now concentrate on more advanced clinical applications, such as the planning of radiotherapy, the response evaluation after the induction of therapy, the early detection of recurrence. Technical innovations, such as PET cameras with better spatial resolution and hybrid positron emission tomography/computed tomography (PET-CT), available now on the whole territory, provide both anatomic and metabolic information in the same procedure. From the point of view of biological metabolism, new radiopharmaceutical probes are being developed. Those hold promise for future refinements in this field. This article reviews the current applications of F.D.G.-PET in patients with cervix cancer. (authors)

    The Cervical Cancer gene DataBase (CCDB, http://crdd.osdd.net/raghava/ccdb) is a manually curated catalog of experimentally validated genes that are thought, or are known to be involved in the different stages of cervical carcinogenesis. In spite of the large women population that is presently affected from this malignancy still at present, no database exists that catalogs information on genes associated with cervical cancer. Therefore, we have compiled 537 genes in CCDB that are linked with cervical cancer causation processes such as methylation, gene amplification, mutation, polymorphism and change in expression level, as evident from published literature. Each record contains details related to gene like architecture (exon-intron structure), location, function, sequences (mRNA/CDS/protein), ontology, interacting partners, homology to other eukaryotic genomes, structure and links to other public databases, thus augmenting CCDB with external data. Also, manually curated literature references have been provided to support the inclusion of the gene in the database and establish its association with cervix cancer. In addition, CCDB provides information on microRNA altered in cervical cancer as well as search facility for querying, several browse options and an online tool for sequence similarity search, thereby providing researchers with easy access to the latest information on genes involved in cervix cancer.

    High dose rate intracavitary irradiation for cancer of the uterine cervix was examined. The 5-year survival rate of this method showed no significant difference from that of the low dose rate intracavitary irradiation, nor did the onset of regional injury show any difference. The optimal dose for stage 1 and 2 was 2900 +- 300 rad, which was approx. 60% of that of the low dose rate method. Elevation of ESR affected the survival rate only in stage 3 and 4 cases. The 5-year survival rate of cases with normal kidney function was twice that of abnormal cases. Radiotherapy of cancer of uterine cervix produced a 5-year survival rate of 58.8% and a cancer morbidity rate of 33.1%; patients with metastasis cannot be cured. The basic form of dose distribution by intracavitary irradiation was tumbler of Manchester's technique. The radiation source was placed in accordance with the conditions established by this technique, and the dose distribution was corrected with a computer. (Chiba, N.)

    Cancers of the uterine cervix were classified for prediction of radiosensitivity. They were classified into two types: radioresistant type (R-type), in which the cancer was predominated by the properties of adenocarcinoma and was radioresistant, and radiosensitive type (S-type) in all others. In preoperatively irradiated cases of stage IIb cancer of uterine cervix, 84% of R-type cases showed viable cancer cells, and 84% of S-type cases showed tumor disappearance. In cases of radiotherapy in a period 1965 - 70, 69% of stage II cases and 70% of stage III cases of R-type showed disease progress; for S-type, 88% of stage II and 77% of stage III cases had tumor control. In stage III cases given radiotherapy alone in 1971 and 1972 after the histological features were examined, 82% of R-type cases showed tumor recurrence and 77% of S-type cases had disease control. Problems in the classification and assessment were discussed. (Chiba, N.)

    Cervical cancer has a major impact on the lives of Indian women with an estimated 122, 844 new cases of cervical cancer in the year 2012. About 80% of these cases present in a locally advanced stage leading to high morbidity and mortality. Because of lack of public awareness and infrastructure for screening and early detection in developing countries, this late presentation is likely to continue in the coming years. Radiation therapy has been the treatment of choice for patients with locally advanced cancer cervix. Many clinical trials and meta-analyses have shown a significant improvement in overall and progression-free survival with decreased local and distant recurrences with the use of concurrent chemotherapy with radiation. Most of these trials have been done in women from developed countries where the patient and disease profile are entirely different from ours. Recently, few trials from India have also shown promising results in locally advanced cancer cervix with concurrent chemoradiotherapy but toxicities remain a major concern. Further exploration is required for the use of concurrent chemo radiation prior to incorporating it into routine clinical practice.

    The relationship among the incidence, the time of occurrence, and radiation dose was studied in regard to hemorrhagic cystitis after radiotherapy for carcinoma of the cervix uteri. Of 1004 patients with carcinoma of the cervix uteri observed between 1961 and 1974, 28 (2.8%) had bladder hemorrhage seemingly due to radiation injury (0.7% were serious). Incidences varied every year. The radiation dose was increased from 4000 to 6000 rad after 1971. In addition to this external dose, because the depth-dose has also increased, the rate of bladder hemorrhage has become high. Seven patients with serious bladder hemorrhage were exposed to more than 5000 rad of 60 Co. Bladder hemorrhage occurred comparatively frequently in patients in whom two hila were irradiated. It usually occurred a few years after irradiation (about 1 year after initial rectal hemorrhage). It continued for approximately 1 year in 21 patients, for approximately 3 years in 4 patients, and for approximately 4 years in 3 patients. Adrenochrome (a hemostatic agent) and antiplasmin were used as therapeutic agents. Serious patients improved remarkably when a large amount of diluted formaline solution or conjugated estrogen was administered intravenously. (Namekawa, K.)

    A group of women with carcinoma of the cervix was studied by renography and i.v. pyelography. The incidence of renal and urinary tract disorders detected by these tests increased as did the stage of the disease, being 17.1% with Stage I carcinoma of the cervix, 27.8% with Stage II carcinoma of the cervix, 47% with Stage III carcinoma of the cervix, and 83.3% in Stage IV carcinoma of the cervix. In patients with Stage I and Stage II carcinoma of the cervix, those selected for radiotherapy had twice the incidence of abnormal renograms as those selected for surgery. This difference probably reflected a higher incidence of medical disorders affecting renal and urinary tract function in those considered unfit for surgery. We believe that renograms should be used routinely as a screening test in patients with carcinoma of the cervix. (orig.) [de

    Computed tomography(X-CT) of squamous cell carcinoma of the uterine cervix was done before and after radiotherapy in forty cases. Changes on X-CT images and its relationship to local control are discussed. Volume of the cervix measured by X-CT is turned out to be a very important factor in radiotherapy of carcinoma of the uterine cervix. 2 cases whose volumes of the cervix exceed 100 cc before radiotherapy failed to obtain local control (p 0.005). After radiotherapy in 6 cases whose volumes of the cervix were more than 20 cc, 5 cases of all failed in local and in 33 cases whose volumes of the cervix were less than 20 cc, 32 cases of all obtained 1 year local control (p < 0.001). In about half cases in which contrast medium was administered low density areas in cervix were observed, in most of all this low density area disappeared after radiotherapy. In the cases in which this low density remained, 3 out of 4 cases failed locally. (author)

    The adult uterine cervix may exhibit a wide variety of pathologic conditions that include benign entities (eg, cervicitis, hyperplasia, nabothian cysts, cervical polyps, leiomyomas, endometriosis, and congenital abnormalities) as well as malignant lesions, particularly cervical carcinoma. In addition, lesions that arise in the uterine body may secondarily involve the cervix, such as endometrial carcinoma and prolapsed intracavitary masses. Many of these conditions can be identified and characterized at ultrasonography (US), which is considered the first-line imaging examination for the female pelvis. However, examination of the cervix is often cursory during pelvic US, such that cervical disease may be overlooked or misdiagnosed. Transabdominal US of the cervix may not afford sufficient spatial resolution to depict cervical disease in many patients; therefore, endovaginal US is considered the optimal technique. Use of supplemental imaging techniques, particularly the application of transducer pressure on the cervix, may be helpful. This review describes the normal appearance of the cervix at US, the appearance of cervical lesions and conditions that mimic abnormalities at US, and optimal US techniques for evaluation of the cervix. This information will help radiologists detect and diagnose cervical abnormalities more confidently at pelvic US. Online supplemental material is available for this article. (©)RSNA, 2016.

    Initial experiments in the present study investigated the effects of epidermal growth factor (EGF), interleukin 1beta (IL-1beta) and sodium nitroprusside (a nitric oxide donor) on the output of prostaglandins from guinea-pig uterus on day 7 of the oestrous cycle. Superfusion of day 7 guinea-pig uterus in vitro with either EGF or sodium nitroprusside increased the output of PGF(2alpha) and 6-keto-PGF(1alpha), but not of PGE(2). IL-1beta had no effect on the output of these three prostaglandins. EGF still increased the output of PGF(2alpha), but did not increase the output of 6-keto-PGF(1alpha) in a calcium-depleted superfusate. Subsequent experiments investigated the effect of sodium nitroprusside on contractile activity of day 7 guinea-pig uterus. Basal spontaneous activity of both the intact uterus and isolated myometrium superfused in vitro was low. Sodium nitroprusside increased the contractile activity of these tissues two- to fourfold. EGF did not affect the contractile activity of the uterus, indicating that sodium nitroprusside-induced contractions are not due to increased prostaglandin production. Overall, the findings indicate that EGF and nitric oxide may act as mediators in the mechanism by which oestradiol acting on a progesterone-primed uterus stimulates the increase in PGF(2alpha) production by the guinea-pig uterus necessary for luteolysis. Nitric oxide may increase the spontaneous activity of the uterus when this activity is low.

    Purpose: To evaluate the magnitude of cervix regression and motion during external beam chemoradiation for cervical cancer. Methods and Materials: Sixteen patients with cervical cancer underwent computed tomography scanning before, weekly during, and after conventional chemoradiation. Cervix volumes were calculated to determine the extent of cervix regression. Changes in the center of mass and perimeter of the cervix between scans were used to determine the magnitude of cervix motion. Maximum cervix position changes were calculated for each patient, and mean maximum changes were calculated for the group. Results: Mean cervical volumes before and after 45 Gy of external beam irradiation were 97.0 and 31.9 cc, respectively; mean volume reduction was 62.3%. Mean maximum changes in the center of mass of the cervix were 2.1, 1.6, and 0.82 cm in the superior-inferior, anterior-posterior, and right-left lateral dimensions, respectively. Mean maximum changes in the perimeter of the cervix were 2.3 and 1.3 cm in the superior and inferior, 1.7 and 1.8 cm in the anterior and posterior, and 0.76 and 0.94 cm in the right and left lateral directions, respectively. Conclusions: Cervix regression and internal organ motion contribute to marked interfraction variations in the intrapelvic position of the cervical target in patients receiving chemoradiation for cervical cancer. Failure to take these variations into account during the application of highly conformal external beam radiation techniques poses a theoretical risk of underdosing the target or overdosing adjacent critical structures

    2011-11-01

    Full Text Available  Uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis (OHVIRA Syndrome is a rare congenital anomaly of the female genital tract. Uterus didelphys occurs when the midline fusion of the mullerian ducts is arrested, either completely or incompletely. Women with didelphic uterus may be asymptomatic and unaware of having a double uterus. They may present with complaints of dysmenorrhoea and dyspareunia. A 25 year old woman attending the infertility clinic at Nizwa regional referral hospital presented with history of dysmenorrhoea and foul vaginal discharge with right cystic pelvic mass. She was diagnosed as a case of double uterus with obstructed right hemivagina and right pyocolpos with ipsilateral renal agenesis after routine ultrasonography in the clinic followed by MRI. Excision of the right vaginal septum with drainage of 200 ml of purulent discharge was performed. She was relieved of her symptoms and conceived promptly after the surgical excision of the partial vaginal septum.

    Twenty-four patients with carcinoma of the cervix were examined preoperatively by MR imaging and CT. In all patients histopathologic confirmation was available for specimens obtained either by radical hysterectomy or at staging laparotomy. MR imaging was equivalent to contrast CT in the detection and evaluation of tumor extension in the cervix. Tumor extension to the parametria and pelvic wall was difficult to evaluate on both modalities, as neither had a higher accuracy than pelvic examination conducted under anesthesia. Nodal staging was nearly equivalent on MR imaging and CT. In the detection and staging of carcinoma of the cervix, MR imaged proved to be as good as CT with contrast agent enhancement

    A method is suggested that permits specifying the primary tumor size on the basis of clinical examination of patients with cervix uteri carcinoma. The values of tumor size have been correlated with long-term results of concomitant radiotherapy in 1358 patients with cervix uteri carcinoma. The data obtained have shown that the primary tumor size is a factor that determines to a large extent radiotherapeutic results in patients with cervix uteri carcinoma. The specification of tumor size values makes it possible to considerably lessen prognostic uncertainty of present-day staging classifications. The structure of radiotherapeutic failures also turned out to be closely associated with the primary tumor size

    Successful implantation requires intimate interactions between a competent blastocyst and a receptive uterus. We recently demonstrated that the aberrant activation of opioid signaling by exogenous ligands adversely affects preimplantation embryonic development and subsequent implantation in mice. However, the underlying machinery governing the dynamic homeostasis of the endogenous opioid system in the uterus during early pregnancy remains elusive. We now show that all three major endogenous opioid precursors are spatiotemporally expressed in the uterus during early pregnancy. Moreover, we observe the well-coordinated expression of the synthetic enzyme prohormone convertases 1/3 (PC1/3) at lower levels and of its inhibitor proprotein convertase subtilisin/kexin type 1 inhibitor (Pcsk1n) and the degrading enzyme membrane metallo-endopeptidase (MME) at higher levels in the receptive uterus. Both estrogen and progestin tend to reduce the uterine levels of opioid ligand precursors in the ovariectomized mouse model. This tight regulation of the endogenous opioid system by PC1/3, Pcsk1n and MME has been further confirmed in physiologically related pseudopregnancy and delayed implantation mouse models. The coordinated regulation of opioid precursor biosynthesis and metabolism helps to create appropriate opioid signaling ensuring uterine receptivity for implantation. Thus, endogenous uterine opioid levels are primarily determined by the coordinated expressions of PC1/3, Pcsk1n and MME under the influence of ovarian progestin and estrogen. Our findings raise an additional cautionary note regarding the effects of opioid abuse on early pregnancy events.

    Science.gov (United States)

    Murphy, Bridget F; Parker, Scott L; Murphy, Christopher R; Thompson, Michael B

    2010-10-01

    We have discovered a modification of the uterus that appears to facilitate maternal-fetal communication during pregnancy in the scincid lizard Eulamprus quoyii. A vessel-dense elliptical area (VDE) on the mesometrial side of the uterus expands as the embryo grows, providing a large vascular area for physiological exchange between mother and embryo. The VDE is already developed in females with newly ovulated eggs, and is situated directly adjacent to the chorioallantois of the embryo when it develops. It is likely that signals from the early developing embryo determine the position of the VDE, as the VDE is off-centre in cases where the embryo sits obliquely in the uterus. The VDE is not a modification of the uterus over the entire chorioallantoic placenta, as the VDE is smaller than the chorioallantois after embryonic stage 33, but expansion of the VDE and growth of the chorioallantois during pregnancy are strongly correlated. The expansion of the VDE is also strongly correlated with embryonic growth and increasing embryonic oxygen demand (Vo2). We propose that angiogenic stimuli are exchanged between the VDE and the chorioallantois in E. quoyii, allowing the simultaneous growth of both tissues.

    Kang Sunghyun

    2011-07-01

    Full Text Available Abstract Many important molecular events associated with implantation and development occur within the female reproductive tract, especially within the uterus endometrium, during pregnancy periods. The endometrium includes the mucosal lining of the uterus, which provides a suitable site for implantation and development of a fertilized egg and fetus. To date, the molecular cascades in the uterus endometrium during pregnancy periods in pigs have not been elucidated fully. In this study, we compared the functional regulated proteins in the endometrium during pregnancy periods with those in non-pregnant conditions and investigated changes in expression patterns during pregnancy (days 40, 70, and 93 using two-dimensional gel electrophoresis (2-DE and western blotting. The functional regulated proteins were identified and discovered from differentially expressed proteins in the uterus endometrium during pregnancy. We discovered 820 protein spots in a proteomic analysis of uterus endometrium tissues with 2-DE gels. We identified 63 of the 98 proteins regulated differentially among non-pregnant and pregnant tissues (matched and unmatched spots. Interestingly, 10 of these 63 proteins are development-, cytoskeleton- and chaperon-related proteins such as transferrin, protein DJ-1, transgelin, galectin-1, septin 2, stathmin 1, cofilin 1, fascin 1, heat shock protein (HSP 90β and HSP 27. The specific expression patterns of these proteins in the endometrium during pregnancy were confirmed by western blotting. Our results suggest that the expressions of these genes involved in endometrium function and endometrium development from early to late gestation are associated with the regulation of endometrium development for maintaining pregnancy.

    A project on the use of computerize planning and dosimetry for brachytherapy in carcinoma of cervix was started at NORI (Nuclear Medicine, Oncology and Radiotherapy Institute, Islamabad) in september 1990. A total number of 182 patients were included in the study over a period of three years. The treatment of all these patients was done by external radiation as well as the intracavitary therapy. Planning and dosimetry was done according to ICRU 38 recommendations. 70 patients were planned with two computers TP-II (Dr. J. Cunningham's software) and PC based system (Dr. Kallinger's software, BTI system). From the results of the two computers TP-II and PC, it can be seen that the difference in a absorbed dose for all recommended points in not going to harm the patient. The dose to the bladder and the rectum in our studies is quite low because of the low activity in the ovoid sources. (author)

    Between April 1968 and December 1980, 61 patients with phase III cancer of the cervix were treated. Fifty-six of them were squamous-cell carcinomas and five adenocarcinomas. The treatment consisted of a combination of external irradiation at doses varying between 4,000 and 7,000 rads and intracavitary radiotherapy with doses of 4.000 to 6.000 MHz, according to the schemes of the D.M. Anderson of Houston. The results obtained as far as survival is concerned and calculated by the actuarial method were 40% after five and ten years. The local control rate reached was 74%. The severe complications caused by the treatment reached 8.1%.

    The population selected for this study was a group of 410 Stage IIB and III squamous cell Ca cervix patients treated at the Radiumhemmet between the years 1958-1966. A total of 48 of these patients developed moderate-to-severe rectal and/or bladder complications. Of these, 33 were evaluable with respect to dose-dependence of complications, that is, complete intracavitary dose measurements and external beam dose calculations, no chemotherapy or electrocautery, and complete clinical radiotherapy records. A group of 57 randomly selected uninjured patients were used as controls. Results show good correlation between dose, expressed in TDF units, and complication rates for both rectal and bladder injuries. Severity of rectal injury was observed to increase with increase in dose, although no such correlation was observed for bladder injuries. Mean delays in the expression of symptoms of injury were 10 months for the rectum and 22 months for the bladder

    Remodeling of the cervix occurs in advance of labor both at term and at preterm birth. Morphological characteristics associated with remodeling in rodents were assessed in cervix biopsies from women at term (39 weeks' gestation) and preterm (cervix biopsies from women in labor at term and preterm compared to that in the cervix from nonlaboring women. Extracellular collagen was more degraded in sections of cervix from women at term, based on optical density of picrosirius red stain, versus that in biopsies from nonpregnant women. However, collagen structure was unchanged in the cervix from women at preterm labor versus the nonpregnant group. As an indication of inflammation, cell nuclei density was decreased in cervix biopsies from pregnant women irrespective of labor compared to the nonpregnant group. Moreover, CD68-stained macrophages increased to an equivalent extent in cervix subepithelium and stroma from groups in labor, both at term and preterm, as well as in women not in labor at term. Evidence for a similar inflammatory process in the remodeled cervix of women at term and preterm birth parallels results in rodent models. Thus, a conserved final common mechanism involving macrophages and inflammation may characterize the transition to a ripe cervix before birth at term and in advance of premature birth. © The Author(s) 2015.

    Purpose : Patients with cervical cancer who have positive resection margins after radical hysterectomy are at increased risk for local recurrence. The results of postoperative pelvic radiotherapy for cervix cancer with positive resection margins were analyzed to evaluated the role of radiotherapy. Materials and Methods : Between 1979 and 1992, 60 patients of cervix carcinoma were treated with postoperative radiotherapy after radical hysterectomy because of positive vaginal(48 patients) or parametrial resection margins(12 patients). Patients were treated with external beam radiation therapy(EBRT) alone (12 patients) or EBRT plus vaginal ovoid irradiation (VOI) (48 patients). The median follow-up period was 5 months. Results : The 5-year actuarial disease free and overall survival rates for all patients were 75.2%, 84.1%, respectively. The overall recurrence rate was 23%(14/60). In 48 patients with positive vaginal resection margins, the pelvic recurrence was 8%(4/48). Distant metastasis was 15%(7/48). Of the 43 patients with positive vaginal resection margins treated with EBRT and VOI, recurrence rate was 21%(9/43), while recurrence rate was 40%(2/5) in the EBRT only treated group. In 12 patients with positive parametrial margins, three patients (25%) had distant metastases. The most significant prognostic factor was lymph node metastasis. Complications resulting from radiotherapy occurred at a rate of 32%(19/60) and grade III complications occurred in three patients (5%). Conclusion : Postoperative radiotherapy can produce excellent pelvic control rates in patients with positive resection margins. In patients with positive vaginal margins, whole pelvic EBRT and BOI is recommended

    The aim of this study was to evaluate brachytherapy as the only treatment modality in inoperable early cervix carcinoma patients (carcinoma in situ, IA and IBocc). In a retrospective analysis 36 patients were treated with intracavitary irradiation between 1984 and 1988 in the Radiotherapy Department of the National Institute of Neoplasmic Diseases. Distribution by stage was; carcinoma in situ: one patient (2,47%), IA: six patients (16,6%), IBooc: twenty-nine patients (80,7%). Histology revealed epidermoid carcinoma in all cases. Mean age 55 years (range: 32-78). Treatment consisted in: two intracavitary applications of Radium, for 120 hours each, with a month interval, in 30 patients (carcinoma in situ: one, IA: four, IBocc: twenty-five patients), two applications of 72 hours each, with 15 days interval in four patients (IA: one, IBocc: 3) and one single intracavitary radium application in two patients (IA and IBocc). Local control was complete in all carcinoma in situ and IA patients. Only 1 of 29 patients with IBocc stage failed to respond, in spite of having received two applications, this shows that local response is independent of the number of insertions. Incidence of complications was low, and resolved with medical treatment. One patient had rectal adenocarcinoma 3 years after treatment -it was considered as radio induced neoplasm, since time of appearance was more than two years and localization was within irradiated area. Two patients died form intercurrent diseases, one (IBocc) from persistent diseases. Two patients were lost to follow-up. Three years survival was: 100% for carcinoma in situ and IA 86,2% for IBocc. Five years survival was 80% for IA and IBocc. Brachytherapy as unique modality of treatment is highly effective in initial cervix carcinoma stages. (author). 41 refs., 14 tabs., 2 figs., 1 ill

    To assess the efficacy of the use of accelerated hyperfractionated radiotherapy (AHRT) for locally advanced uterine cervix cancers. Between May 2000 and September 2002, 179 patients were identified with FIGO stage IIB, IIIB, and IVA cancers. Of the 179 patients, 45 patients were treated with AHRT (AHRT group) and 134 patients were treated with conventional radiotherapy (CRT group), respectively. Patients undergoing the AHRT regimen received a dose of 30 Gy in 20 fractions (1.5 Gyx2 fractions/day) to the whole pelvis. Subsequently, with a midline block, we administered a parametrial boost with a dose of 20 Gy using 2 Gy fractions. Patients also received two courses of low-dose-rate brachytherapy, up to a total dose of 85∼90 Gy to point A. In the CRT group of patients, the total dose to point A was 85∼90 Gy. The overall treatment duration was a median of 37 and 66 days for patients that received AHRT and CRT, respectively. Statistical analysis was calculated by use of the Kaplan-Meier method, the log-rank test, and Chi-squared test. For patients that received cisplatin-based concurrent chemotherapy and radiotherapy, the local control rate at 5 years was 100% and 79.2% for the AHRT and CRT group of patients, respectively (p=0.028). The 5-year survival rate for patients with a stage IIB bulky tumor was 82.6% and 62.1% for the AHRT group and CRT group, respectively (p=0.040). There was no statistically significant difference for severe late toxicity between the two groups (p=0.561). In this study, we observed that treatment with AHRT with concurrent chemotherapy allows a significant advantage of local control and survival for locally advanced uterine cervix cancers

    To determine the risk of cesarean delivery associated with postdates induction (≥41 weeks) compared to term induction (37-40w6d) among women with an unfavorable cervix, and to examine the risk factors associated with cesarean among women undergoing postdates induction. A planned secondary analysis of a large prospective cohort study on induction (n = 854) was performed. Women with a singleton gestation, intact membranes, and an unfavorable cervix (Bishop score of ≤6 and dilation ≤2 cm) who were undergoing a term (≥37 weeks) induction for any indication were included. Women with a prior cesarean were excluded. The primary outcome was cesarean delivery. Relative risk of cesarean was estimated using a modified Poisson's regression model. There was a significantly increased risk of cesarean for women undergoing postdates induction (n = 154) compared to women 37-40w6d (n = 700), (46.8 versus 26.0%, p cesarean remained after adjustment for race, parity, and pregnancy-related hypertension (aRR 1.70 [1.39-2.09], p cesarean among women ≥41 weeks included nulliparity (aRR 3.38 95%CI (2.42-4.74)), BMI ≥30 (aRR 1.72 95%CI (1.34-2.21)), and starting cervical dilation cesarean compared to women 37-40w6d, with nulliparity, obesity, and cervical dilation <1 cm being independent risk factors. These data can be used to augment patient counseling and support the ongoing discussion regarding the risk of post dates induction.

    Adolescence and pregnancy are considered to be risk factors for human papillomavirus (HPV) infection. The relationship between this infection in the uterine cervix and oral HPV infection is controversial. This report describes a case of a pregnant 16-year-old adolescent who presented HPV infection in the uterine cervix and the mouth. Smears were collected from the cervix and the tongue/palate. Dental biofilm samples were also collected. The microarray technique was used to detect HPV. The HPV 56 subtype was observed in the cervical smear and HPV 6 in dental biofilm. In this pregnant adolescent, HPV infection was present in both the cervix and the mouth, but the HPV subtypes infecting these two areas were different.

    Full Text Available The p53 codon 72 polymorphism seems to be associated with HPV-carcinogenesis, although controversial data have been reported. A series of Brazilian women with cervix carcinomas were analyzed. Ninety-nine (67% of 148 women were found to be homozygous (arg/arg for the arginine polymorphism, and 49 (33% were heterozygous (arg/pro. This polymorphism may be an important determinant of the risk for cervix cancer, but does not seem to be sufficient for carcinogenesis.

    Cervical softness is a critical parameter in pregnancy. Clinically, preterm birth is associated with premature cervical softening and post-dates birth is associated with delayed cervical softening. In practice, the assessment of softness is subjective, based on digital examination. Fortunately, objective, quantitative techniques to assess softness and other parameters associated with microstructural cervical change are emerging. One of these is shear wave speed (SWS) estimation. In principle, this allows objective characterization of stiffness because waves travel more slowly in softer tissue. We are studying SWS in humans and rhesus macaques, the latter in order to accelerate translation from bench to bedside. For the current study, we estimated SWS in ex vivo cervices of rhesus macaques, n=24 nulliparous (never given birth) and n=9 multiparous (delivered at least 1 baby). Misoprostol (a prostaglandin used to soften human cervices prior to gynecological procedures) was administered to 13 macaques prior to necropsy (nulliparous: 7, multiparous: 6). SWS measurements were made at predetermined locations from the distal to proximal end of the cervix on both the anterior and posterior cervix, with 5 repeat measures at each location. The intent was to explore macaque cervical microstructure, including biological and spatial variability, to elucidate the similarities and differences between the macaque and the human cervix in order to facilitate future in vivo studies. We found that SWS is dependent on location in the normal nonpregnant macaque cervix, as in the human cervix. Unlike the human cervix, we detected no difference between ripened and unripened rhesus macaque cervix samples, nor nulliparous versus multiparous samples, although we observed a trend toward stiffer tissue in nulliparous samples. We found rhesus macaque cervix to be much stiffer than human, which is important for technique refinement. These findings are useful for guiding study of cervical

    Compared to controls, diabetes results in higher plasma, liver and kidney Cu concentrations. Since alterations in Cu metabolism may be associated with diabetic pathology, the authors investigated how Cu metabolism is affected by diabetes and dietary Cu intake. Nondiabetic and STZ diabetic rats were fed Cu suppl. or Cu def. diets for 5 wks. Rats were intubated with 28 μCi 67 Cu and killed after 8, 16, 24, 32, 64, or 128 h. There were marked effects of both diet and diabetes on 67 Cu metabolism. Independent of diabetes, deficient rats had a higher % of retained 67 Cu, in liver, plasma, RBC, muscle, spleen, brain, lung, uterus, and intestine than adequate Cu rats. Independent of dietary Cu, diabetic rats had a lower % of retained 67 Cu in liver, plasma, RBC, muscle, spleen, lung, bone, pancreas, skin, uterus and heart than controls. Differential effects were noted for kidney; adequate Cu diabetic rats had a higher % of retained 67 Cu than all other groups. Marked effects of both diet and diabetes were evident when tissue Cu turnover was examined. Compared to Cu suppl. rats, Cu def. rats had a slower turnover of 67 Cu, in liver, plasma, intestine, pancreas, eye, brain, muscle, spleen, lung and heart. Diabetic rats had a slower turnover of 67 Cu than nondiabetic rats in liver, plasma, intestine, pancreas, eye, kidney, RBC and uterus. The data imply that a focus on Cu metabolism with regard to cellular Cu trafficking and pathology may be warranted

    ABSTRACT The extracellular matrix of the cervix that comprises collagen, elastin, proteoglycans and glycosaminoglycans (GAGs) is thought to have an essential role in cervical relaxation. This study investigated the proportion of collagen and smooth muscle as well as the GAGs in cervices obtained from healthy bitches at different stages of the estrous cycle and bitches with open- and closed-cervix pyometra. Cervices were collected after ovariohysterectomy. The proportion of collagen to smooth muscle was determined using Masson’s trichrome staining. Alcian blue staining was used to evaluate the relative distribution of cervical GAGs. The proportion of cervical collagen relative to smooth muscle was higher at estrus compared to anestrus (P≤0.05). It was also higher (P≤0.05) in bitches with open- compared to those with closed-cervix pyometra. Overall, hyaluronan (HA) was the predominant GAG in the canine cervix. In the luminal epithelium, the staining intensity for HA was stronger in estrus than in anestrus (P≤0.05), but not in diestrus (P>0.05). On the contrary, the intensity for the combined keratan sulfate (KS) and heparan sulfate (HS) was stronger in anestrus than in estrus and diestrus (P≤0.05). In bitches with pyometra, the staining intensity of the stroma for KS and HS was weaker in open- compared to closed-cervix pyometra (P≤0.05). Collectively, the different profiles of collagen and GAG suggest that the metabolism of both collagen and GAGs in the canine cervix is associated with hormonal statuses during the estrous cycle and cervical patency of bitches with pathological uterine conditions, such as pyometra.

    Radiotherapy for cervix cancer is challenging in patients exhibiting large daily changes in the pelvic anatomy, therefore adaptive treatments (ART) have been proposed. The aim of this study was the clinical implementation and subsequent evaluation of plan-of-the-day (POTD)-ART for cervix cancer in supine positioning. The described workflow was based on standard commercial equipment and current quality assurance (QA) methods. A POTD strategy, which employs a VMAT plan library consisting of an empty bladder plan, a full bladder plan and a motion robust backup plan, was developed. Daily adaption was guided by cone beam computed tomography (CBCT) imaging after which the best plan from the library was selected. Sixteen patients were recruited in a clinical study on ART, for nine POTD was applied due to their large organ motion derived from two computed tomography (CT) scans with variable bladder filling. All patients were treated to 45Gy in 25 fractions. Plan selection frequencies over the treatment course were analyzed. Daily doses in the rectum, bladder and cervix-uterus target (CTV-T) were derived and compared to a simulated non-adapted treatment (non-ART), which employed the robust plan for each fraction. Additionally, the adaption consistency was determined by repeating the plan selection procedure one month after treatment by a group of experts. ART-specific QA methods are presented. 225 ART fractions with CBCTs were analyzed. The empty bladder plan was delivered in 49% of the fractions in the first treatment week and this number increased to 78% in the fifth week. The daily coverage of the CTV-T was equivalent between ART and the non-ART simulation, while the daily total irradiated volume V42.75Gy (95% of prescription dose) was reduced by a median of 87cm 3 . The median delivered V42.75Gy was 1782cm 3 . Daily delivered doses (V42.75Gy, V40Gy, V30G) to the organs at risk were statistically significantly reduced by ART, with a median difference in daily V42.75Gy in

    Objective: Small cell carcinoma of the uterine cervix is a rare and aggressive tumor. This tumor is similar to small cell carcinoma of the lung with a tendency to metastasize early. While there has been an increasing interest in the use of chemotherapy regimens similar to those used for small cell carcinoma of the lung, the optimum local therapy for small cell carcinoma of the cervix remains unknown. We reviewed the treatment outcome of patients with small cell carcinoma of the cervix diagnosed in our cancer center with an emphasis on the local/regional disease control. Material and Methods: Between 1983 and 1993, medical records of patients diagnosed with carcinoma of the uterine cervix were reviewed. There were 281 patients with carcinoma of the uterine cervix referred to our department for radiation treatment. Seven patients had pathologic diagnosis of either small cell or neuroendocrine histology. Details of the treatments and follow-up information of these patients were reviewed with a medium follow-up period of three years (range - 1 to 4 years). Results: Five patients had pure small cell histology. Two patients had mixed histology: one with mixed small cell anaplastic neuroendocrine cells and a small foci of adenocarcinoma, the other had mixed small cell and squamous cell histology. Four patients had clinical stage IB disease. The others had IIA, IIB, and IIIB disease, respectively. All patients received either irradiation (XRT) alone or as part of the local therapy. Three patients received XRT alone, one received surgery followed by XRT, one received XRT followed by surgery, and the remaining two had triple modality treatment (chemotherapy, surgery, and XRT). Three patients were alive without evidence of disease recurrence at the last follow-up. Two of these received adjuvant chemotherapy in addition to local therapy. The third patient, whose tumor was smaller than one cm at the time of diagnosis, received XRT alone. Four patients died with disease

    This study was conducted to evaluate the treatment results, prognostic factors, and complication rates after high dose rate (HDR) brachytherapy in patients with uterine cervix cancer who were treated with curative aim. Of 269 cervix cancer patients treated at the department of radiation oncology, Samsung Medical Center from September 1994 to July 1998, the 106 who were treated with radical radiotherapy were analyzed. The median age was 61 years (range 22 to 89). All patients except 4 with carcinoma in situ (CIS) were given external beam radiotherapy (range 30.6 {approx} 50.4 Gy to whole pelvis) and HDR brachytherapy. The common regimens of HDR brachytherapy were a total dose of 24 {approx} 28 Gy with 6 {approx} 7 fractions to point A at two fractions per week. The median overall treatment time was 55 days (range 44 to 104) in patients given both external beam radiotherapy and HDR brachytherapy. Early response of radiotherapy were evaluated by gynecologic examination and follow-up MRI 1 month after radiotherapy. Treatment responses were complete remission in 72 patients, partial response in 33 and no response in 1. The overall survival (OS) rate of all patients was 82%, and 73%, and the disease free survival (DFS) rate was 72%, and 69%, at 3, and 5 years, respectively. The pelvic control rate (PCR) was 79% at both 3 and 5 years. According to the FIGO stage, 3 and 5 year OS were 100% and 50% in CIS/IA, 100% in 100% in IB, 83% and 69% in IIA, 87% and 80% in IIB, and 62% and 62% in III, respectively. The 3 year OS in 4 patients with stage IVA was 100%. Three-year DFS were 80% in CIS/IA, 88% in IB, 100% in IIA, 64% in IIB, 58% in III, and 75% in IVA. Three-year PCR were 100% in CIS/IA, 94% in IB, 100% in IIA, 84% in IIB, 69% in III, and 50% in IVA. By univariate analysis, FIGO stage and treatment response were significant factors for OS. The significant factors for DFS were age, FIGO stage, treatment response and overall treatment time (OTT). For pelvic control rate

    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) cm 3 and it was reduced to (17.7 ± 13.1) cm 3 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)

    To describe the histologic distribution of elastin in the nonpregnant human uterus, uterine leiomyomas, adenomyosis and adenomyomas. Uteri were obtained from women undergoing hysterectomy for benign conditions, including 26 cases of uterine leiomyomas, 24 cases of adenomyosis, 18 adenomyomas and 6 cases of autopsy specimens. Specific histochemical staining techniques were employed in order to demonstrate the distribution of elastin. The distribution of elastin components in the uterus was markedly uneven and showed a decreasing gradient from outer to inner myometrium. No elastin was present within leiomyomas, adenomyomas or adenomyosis. The distribution of elastin may help explain the normal function of the myometrium in labor. It implies that the uneven distribution of elastin components and absence of elastin within leiomyomas, adenomyomas and adenomyosis could be of some clinical significance. The altered elastin distribution in disease states may help explain such symptoms as dysmenorrhea in uterine endometriosis.

    Young women with breast cancer face contraceptive challenges. Data are limited and conflicting on the use of the levonorgestrel intrauterine device (LNG-IUD) in this patient population. A 32-year-old nulligravid woman with a history of breast cancer on tamoxifen presented with new-onset vaginal bleeding. Further workup revealed a previously undiagnosed bicornuate uterus. She underwent hysteroscopy, dilation and curettage, and LNG-IUD placement in each uterine horn. Postoperative follow-up confirmed retention and proper placement of both IUDs. Pathology from the dilation and curettage was benign, and the abnormal uterine bleeding abated. LNG-IUD placement in a young patient with a personal history of breast cancer on tamoxifen and a bicornuate uterus is a safe and feasible alternative for contraception. Copyright © 2016 AAGL.

    Imaging in the major planes (horizontal, coronal, and sagittal) of the uterus is important for determining anatomy and allowing the findings to be standardized, and for evaluating and diagnosing different pathological conditions in clinical practice. Examination of the coronal plane is an important step in identifying uterine pathologies and their relationships to the endometrial canal. Three-dimensional (3D) ultrasound reveals the normal anatomy better and improves the depiction of abnormal anatomy, as the coronal plane of the uterus can easily be obtained using 3D reconstruction techniques. Our pictorial essay demonstrates that adding 3D ultrasound to a routine gynecological workup can be beneficial for clinicians, enabling a precise diagnosis to be made. In addition, the volumes obtained and stored by 3D ultrasound can allow students or residents to become more familiar with normal and abnormal pelvic structures. Clin.

    We present a case of a patient with Uterus bicornis bicollis, imperforate hemivagina and ipsilateral renal agenesis. This group of congenital malformations is often asymptomatic until puberty, when it presents as cyclic dysmenorrhoea, leucorrhoea or a pelvic mass. Magnetic resonance imaging is becoming the preferred modality for delineation of uterine malformations. When congenital abnormalities of the reproductive tract are encountered, a search should also be made for renal anomalies. Patients with Uterus bicornis bicollis and unilateral imperforate vagina are often seen with pain severe enough to mimic an acute abdomen. It is important to keep this unusual congenital malformation in mind in the differential diagnosis of vaginal discharge, pelvic mass and/or abdominopelvic pain in young women so as to avoid inappropriate surgical procedures.

    Full Text Available Primary malignant lymphomas in the female genital tract are rare. Most cases are non-Hodgkin lymphomas of which diffuse large B-cell lymphomas are most commonly seen. Symptoms are associated with other, more common diseases; therefore, a doctors’ delay can be expected. In this case a woman presented with complaints of urinary obstruction due to a large tumour in the pelvic area. A laparotomy was performed. A very large tumour of the uterus was found with adherence to the pelvic wall and urinary bladder. Diagnostic histological examination showed a diffuse large B-cell lymphoma. Treatment with R-CHOP chemotherapy was started shortly after the operation. The treatment of patients with a primary malignant lymphoma of the uterus should be individualized with the following options: surgery, radiotherapy and/or chemotherapy.

    Full Text Available INTRODUCTION Radiotherapy is the standard treatment in locally advanced (IIB-IVA and early inoperable cases. The current standard of practice with curable intent is concurrent chemoradiation in which intracavitary brachytherapy is an integral component of radiotherapy. This study aims at assessing the efficacy of HDR ICBT (High-dose rate intracavitary brachytherapy in terms local response, normal tissue reactions, and feasibility. METHODS AND MATERIALS A total of 20 patients of stage IIIB cancer of the uterine cervix were enrolled in the study and were planned to receive concurrent chemotherapy weekly along with EBRT (external beam radiotherapy to a dose of 50 Gy/25 Fr. Suitability for ICBT was assessed at 40 Gy/20 Fr. 6/20 patients were suitable at 40 Gy and received HDR ICBT with a dose of 5.5 Gy to point A in 4 sessions (5.5 Gy/4 Fr. The remaining 14/20 patients completed 50 Gy and received HDR ICBT with a dose of 6 Gy to point A in 3 sessions (6 Gy/3 Fr. RESULTS A total of 66 intracavitary applications were done and only one application required dose modification due to high bladder dose, the pelvic control rate was 85% (17/20. 10% (2/20 had stable disease and 5% (1/20 had progressive disease at one year of follow up. When toxicity was considered only 15% developed grade I and grade II rectal complications. Patient compliance and acceptability was 100%. Patients were very comfortable with the short treatment time as compared with patients on LDR ICBT (low-dose rate intracavitary brachytherapy treatment interviewed during the same period. CONCLUSION This study proves that HDR brachytherapy is efficacious and feasible in carcinoma of cervix stage IIIB. It also proves that good dose distribution can be achieved with HDR intracavitary facility by the use of dose optimization. The short treatment time in HDR ICBT makes it possible to maintain this optimised dose distribution throughout the treatment providing a gain in the therapeutic ratio and

    Full Text Available The aim of the study was to evaluate the influence of sildenafil citrate administrated intravaginaly on the blood flow in the bovine uterus during dioestrus. Uterine blood flow was examined in six healthy adult cows. Sildenafil was administrated intravaginaly to each co w between the 6th and 8th d of the ovarian cycle, in the form of vaginal suppositories containing 100 mg of active substance at a dose of 100, 200, or 300 mg per animal. Uterine perfusion was estimated by the colour Doppler examination, and obtained results were analysed with the Pixel Flux Software (Chameleon, Germany. Moreover, cardiovascular parameters were also evaluated. Animals were examined before and five times after drug application (two times at 15 min intervals, and three times at 2 h intervals. A placebo suppository was also given to the cows. The analysis of the intensity and velocity of blood flow in the uterus proved that sildenafil administrated intravaginaly significantly increased blood flow in the uterus and the effect of increased perfusion was observed for 4 h and 30 min after administration. The effect of increased uterine perfusion was observed after low as well as high doses of sildenafil. Significant changes in the cardio-vascular parameters were not detected. There were no changes in the uterine perfusion as well as in cardiovascular parameters after placebo administration.

    1985-01-01

    The anatomical pattern of nuclear binding of 2-OH[6,9- 3 H]estradiol ([ 3 H]2-OHE 2 ) in brain, pituitary and uterus have been studied autoradiographically. Autoradiograms of forebrain, pituitary and uterus show nuclear concentrations of radioactivity in certain cells. This nuclear concentration is abolished when unlabelled 2-OHE 2 or E 2 was injected prior to the injection of [ 3 H]2-OHE 2 . In the brain nuclear labelling is observed in the septal-preoptic region, in the anterior hypothalamic area, and in the central hypothalamic area. Some estrogen-sensitive nuclear groups, such as lateral septum and hippocampus, do not show accumulation of radioactivity. In the uterus, luminal and glandular epithelium, stromal cell and muscle cells are labelled. A comparison of the quantitative nuclear uptake of radioactivity and of the different time intervals after the injection of different doses shows similar uptake of nuclear radioactivity. This is comparable to data obtained after [6,7- 3 H]estradiol ([ 3 H]E 2 ) injection. The results provide clear evidence for nuclear binding of catechol estrogens of the same magnitude as [ 3 H]E 2 after in vivo treatment. (Auth.).0

    The reproductive tracts of 50 bitches were ultrasonically imaged to evaluate the appearance of the uterus and ovaries at different stages of the oestrous cycle. Ovarian follicular growth was observed throughout the oestrous period. Follicles increased in size slowly until 7 days after the onset of pro-oestrus. Thereafter there was a rapid increase in diameter, indicating impending ovulation. The maximum recorded follicular diameter was 13 mm. It was not possible to observe ovulation since in the bitch follicles do not collapse as rapidly as in other species. During the post-ovulatory period there was a gradual loss of follicle shape and an increase in wall thickness. It was not possible to image the uterus of prepubertal bitches or young nulliparous bitches in anoestrus. During pro-oestrus and oestrus the uterus became increasingly hypoechoic with central regions of hyperechogenicity, which may represent uterine oedema. Uterine involution was observed in 5 bitches, and a rapid change in uterine diameter occurred over the first 3 days post partum. The ultrasonographic appearance was characteristic at this time.

    Background Despite similar frequencies of exposure, the low prevalence of certain sexually transmitted infections such as Chlamydia, HPV and HIV-1 in the oral cavity relative to the cervix is poorly understood. This could be explained in part by differences in host immune microenvironments between these two anatomic sites. Objective We compared the concentration and correlation of 27 different immune markers in paired secretion specimens collected from the oral and cervical mucosa of healthy women. Methods Paired oral and cervical secretion specimens were collected from thirty-nine women. The concentration of twenty-seven different immune markers was estimated using a Luminex multiplex assay. Marker concentration was normalized to total protein present in the specimen. Median immune marker concentrations were compared across anatomic sites. Unsupervised hierarchical clustering analysis was utilized to identify groups of markers that shared similar patterns of relative concentrations across anatomic sites. Results The oral cavity had significantly higher concentrations of eotaxin, IFN-γ, IL-2, IL-4, IL-5, IL-7, IL-9, IL-13, IL-15, PDGF-BB, TNF-α, (p < 0.01 for each) while the cervix had higher concentrations of proinflammatory markers such as FGF-basic, IL-1ra, IL-1β, IL-6, IL-8, IP-10, G-CSF, GM-CSF, MCP-1, MIP-1β, VEGF (p < 0.01 for each). Hierarchical cluster analysis identified two groups of immune markers comprised of T-cell related immune markers with significantly higher concentrations in the oral cavity relative to the cervix, and a third cluster consisting of mostly inflammatory immune markers which were higher concentrations in the cervix. The oral cavity had a larger number of significant inter-marker correlations as compared to the cervix. Conclusions The oral cavity and cervix have significantly different immune marker profiles, which may in part explain the significantly lower burden of sexually transmitted infections such as Chlamydia, HPV, and

    To investigate the distribution of lymphatic tissues and nerves in the supporting ligaments around the cervix uteri for their tomographical relationship, 9 adult female cadavers were used in this study. Following the incision of all supporting ligaments around the cervix, hematoxylin and esosin (H&E) and immunohistochemical staining of various sections of these ligaments was performed to enable the distribution of lymph tissues and autonomic nerves to be observed. Four lymph nodes were identified in three cadaver specimens. Three lymph nodes were present at a distance of 2.0 cm from the cervix in the cranial side of the cardinal ligaments (CLs), and one lymph node was located at a distance of 4.0 cm from the cervix in the cranial side of the uterosacral ligament (USL). The lymphatic vessels were dispersed in the CLs, scattered in the cervical side of the USLs, and occasionally distributed in the vesicouterine ligaments (VULs). In the CLs, parasympathetic nerves were located at the pelvic lateral wall and went downwards and medially into the cervix, while sympathetic fibers were located in the middle and lower parts of the ligaments. In the USLs, the autonomic nerves, which consisted primarily of sympathetic fibers, went downwards and laterally from the pelvic wall to the cervix. In the VULs, parasympathetic and sympathetic nerves were located in the inner sides of the vesical veins in the deep layers of the ligaments. It is concluded that there are few lymphatic tissues in the supporting ligaments around the cervix uteri, and that nerve‑sparing radical hysterectomy (NSRH) may be a safe method for the treatment of early‑stage cervical cancer.

    Okabayashi's extensive panhysterectomy is used for cancer of uterine cervix in Japan, and the rate of its practice was 45.6% at the National Cancer Center (1962 - 73, stage 1 - 4 cases). Cancer death within 5 years occurred in 92.3% of the total deaths, and the total surgical deaths did not exceed 1%. Postoperative irradiation was performed in cases with lymph node metastasis, those with parametrial invasion and those with deep primary lesions. Intravaginal irradiation was sometimes performed in cases of insufficient vaginal excision. Therefore, the 5-year survival rate of postoperatively irradiated cases was 71.4%, and that of non-irradiated cases 93.7%. The 5-year survival rate of all cases of adenocarcinoma including irradiated cases was 44.7%. Since the effect of irradiation was not so promising, postoperative irradiation with fast neutrons is performed in adenocarcinoma cases with metastasis and/or infiltration. Effect of combination with chemotherapy has been poor. The indication of less surgery for early cases is under examination. (Chiba, N.)

    From March 1986 to June 1988, 60 patients with carcinoma of the uterine cervix were treated by radiotherapy alone or combined radiotherapy and surgery at the only radiotherapy-oncology department of Madagascar in Antananarivo. There were 20 stage IB, 28 stage II, 5 stage III and 7 cases where initial stage before surgery was unknown. After a limited pre-therapeutic investigation, treatment for stage IB consisted of utero-vaginal brachytherapy followed by a colpo-hysterectomy and external iliac lymphadenectomy. Others received combined external radiotherapy and brachytherapy according to the Fletcher guidelines, although 30 patients also received surgery. An obsolete and inefficient cobalt unit with lack of computerized dosimetry made the management of therapeutic schemas difficult. Nineteen patients (31.6%) were not available for follow-up immediately after the end of the treatment and one patient died from intestinal occlusion during brachytherapy. The overall rate of severe complications was 4.8%. There were 12 recurrences which occurred in stage II or in patients with unknown initial staging. At the time of analysis, 25 patients were alive: 15 stage I and 10 stage II. In this country, cervical carcinomas are the most frequent tumors: only the rehabilitation of radiotherapy facilities will allow results to be improved

    Human Papilloma Virus infection is very frequent in humans and is mainly transmitted sexually. The majority of infections are transient and asymptomatic, however, if the infection persists, it can occur with a variety of injuries to skin and mucous membranes, depending on the type of HPV involved. Some types of HPV are classified as high oncogenic risk as associated with the onset of cancer. The tumors most commonly associated with HPV are cervical and oropharyngeal cancer, epigenetic mechanisms related to HPV infection include methylation changes to host and viral DNA and chromatin modification in host species. This review is focused about epigenethic mechanism, such as MiRNAs expression, related to cervix and oral cancer. Specifically it discuss about molecular markers associated to a more aggressive phenotype. In this way we will analyze genes involved in meiotic sinaptonemal complex, transcriptional factors, of orthokeratins, sinaptogirin, they are all expressed in cancer in a way not more dependent on cell differentiation but HPV-dependent.

    47 out of 56 cases of intact uterine cervix cancer treated by radiation at the Hanyang University Hospital were followed 18 months or more after treatment. (7 patients died before 18 months, 2 cases lost to follow-up). Age distribution reveal 5 cases in 30's, 18 cases in 40's, 17 cases in 50's, 7 cases in 60's. Histologically, all cases were squamous cell type except one case of adenocarcinoma. 1. 45 cases were treated by combined external Co-60 irradiation and intracavitary irradiation by Cs-137 small sources. 1 case was treated by external irradiation only, and 1 case by intracavitary only. 2. Rectal injuries were observed in 13 cased (27.6%), 4 cases in Grade 1, 8 cased in Grade 2 and 1 cases in Grade 3 which needed surgical management. 3. Average intervals of rectal injury and point A dose reveal 6 cases between 7000-7999 rad and 6 cases between 8000-8999 rad and 1 case above 9000 rad. Even though there is no direct relation between point A dose and rectal injury, it is expected that rectal injury increases as point A dose increase. 4. In the normal condition, rectal injury can't be attributed to one major cause. Radiation dose, small source distribution, general condition of patients, local anatomy of the individual patient, history of PID and previous surgery, all play complex roles

The effect of the side of the uterus/oviduct regarding the ovary bearing a corpus luteum (CL (ipsi vs. contralateral was also analyzed. Fourteen oestrous synchronized ewes were fed either 1.5 (C, n=7 or 0.5 (L, n=7 times their maintenance requirements from the onset of the hormonal treatment (day -14, till slaughter on day 5 post-oestrus. Oviducts and samples of uterus were collected and their gene expression studied by real time RT-PCR. Undernourished ewes had greater PGR expression in the oviduct than control ewes, but lower expression of IGF1 in uterus and of IGF2 in oviducts. The ipsilateral oviduct presented lower expression of PGR, ESR1 and IGF2 mRNA than the contralateral one, but this did not occur in the uterus. In conclusion, there is an effect of undernutrition on gene expression that is transcript and organ dependent (uterus/oviduct. This work reports for the first time that growth factors and sex steroid receptor expression on day 5 after oestrus vary depending on the side of the CL-bearing ovary and the region of the reproductive tract.

    The ultrastructure of the ovary of Fasciola hepatica collected from field-infected sheep, was compared with that of flukes from laboratory-infected rats harbouring the Oberon or the Cullompton fluke isolate. At the periphery of the ovarian tubules, in all flukes, interstitial tissue was identified that appears to provide physical support and facilitate the metabolism of the germinal-line cells. Oogonia undergo mitotic division to maintain the cell population and to produce oocytes. Early oocytes feature conspicuous synaptonemal complexes in the nucleoplasm, and these become less evident as the oocytes grow in size, move towards the core of the ovarian tubule, and synthesise osmiophilic bodies. The latter may represent cortical granules, and serve to block polyspermy. The identity of the synaptonemal complexes was confirmed by immunocytochemical labelling of synaptonemal proteins. The occurrence of synaptonemal complexes in the oocytes of all fluke types examined indicates that pairing of bivalent chromosomes, with the potential for genetic recombination and chiasmata formation, is a feature of the triploid aspermic parthenogenetic Cullompton flukes, as well as of the wild-type out-breeding field-derived and Oberon isolate flukes. In oocytes within shelled eggs in the proximal uterus of all flukes, condensed chromosomes align at meiotic metaphase plates. Following the reduction division, two equal pronuclei appear in each oocyte in the distal uterus. On the basis of these observations, a mechanism of facultative parthenogenesis for F. hepatica is proposed that accommodates the survival and clonal expansion of triploid aspermic isolates.

    Full Text Available Background: Caregivers of individuals suffering from cancer illnesses are at risk of having subjected to mental health consequences. There is a paucity of data comparing the caregiver burden of cancer breast and cancer cervix patients. Aim: The aim of the present study is to compare the caregiver burden of cancer breast and cancer cervix patients. To study the association of caregiver burden with demographic factors like age, gender, duration of caregiving etc. Materials & Methods: This Cross sectional study is performed on the key relatives of patients of 31 cancer cervix and 31 cancer breast patients. Burden assessment schedule was used. Results: Our findings suggest burden is more in male caregivers of breast cancer patients. It is not so in caregivers of cancer cervix patients. Whenever the caregiver is closely related to the patients the burden is high in both groups. Whenever the burden scores were high the depression scores were also high. Treatment modalities as a whole correlates with burden scores in caregivers of breast cancer patients but not in cancer cervix patients. Conclusion: Caregivers with breast and cervical cancer patients are vulnerable if the caregiver is male, from low socioeconomical background, more closely related and when the patients received poor treatment modalities.

Vaginal examination revealed a fragile lesion of size 1×1 cm invading left posterior vaginal fornice and parametrium. Biopsy showed the presence of papillae containing fibrovascular cores lined by multilayered atypical epithelial cells resembling squamous and transitional cell epithelium, confirming the diagnosis of PSTCC of the uterine cervix. After staging work-up she was staged according to the International Federation of Gynecology and Obstetrics (FIGO staging system 2009 as FIGO IIB, and she was started on extended field concurrent chemoradiation. Discussion. PSTCC of the uterine cervix is an extremely rare and aggressive entity. PSTCC is often characterized by the presence of papillary structures with prominent fibrovascular cores. PSTCC of the uterine cervix should be differentiated from transitional cell carcinoma, squamous papilloma, papillary adenocarcinoma, and cervical intraepithelial neoplasia with papillary features. Conclusion. PSTCC of the uterine cervix is a diagnostic challenge; further studies regarding the mechanism underlying the development of PSCC are warranted.

    We sought to determine whether cervical dysplasia in the absence of an excisional procedure is associated with an increased risk of preterm birth (PTB) and whether that risk is independent of the presence of a short cervix. This is a cohort study including women with a singleton pregnancy who underwent routine cervical length assessment between 18-23 6/7 weeks of gestation, stratified by cervical dysplasia (ie, no prior dysplasia, prior dysplasia but no excisional procedure, or prior excisional procedure). The frequency of a short cervix (≤2.5 cm) and PTB were compared between groups and multivariable analyses were performed to identify whether: (1) dysplasia alone or a prior excisional procedure was associated with PTB; and (2) whether these factors remained independently associated with PTB after adjusting for the presence of a short cervix. Of the 18,528 women who met inclusion criteria, 3023 (16.3%) had prior dysplasia alone and 1356 (7.3%) had a prior excisional procedure. The frequency of a short cervix for women without dysplasia, with prior dysplasia alone, or with a prior excisional procedure was 0.8%, 1.0%, and 2.2%, respectively (P cervix.

    Zymbal gland in two males. Body Weights and Survival in the Twenty-One-Month Studies: The average amount of 3,3'-dimethoxybenzidine dihydrochloride consumed per day was approximately 6, 12, or 21 mg/kg for low, mid, or high dose male rats and 7, 14, or 23 mg/kg for low, mid, or high dose female rats. Mean body weights of male and female rats began to decrease relative to those of controls after about 1 year of exposure at 170 or 330 ppm and were 6%-22% lower for males and 7%-17% lower for females. Survival of rats exposed to 3,3'-dimethoxybenzidine dihydrochloride was reduced because animals were dying with neoplasms or being killed in a moribund condition (survival at 21 months--male: control, 44/60, 73%; low dose, 8/45, 18%; mid dose, 0/75; high dose, 0/60; female: 45/60, 75%; 15/45, 33%; 6/75, 8%; 0/60). Because of these early compound-related deaths, the studies were terminated at 21 months. Nonneoplastic and Neoplastic Effects in the Twenty-One-Month Studies: Increased incidences of several nonneoplastic lesions were observed in exposed rats, including hematopoietic cell proliferation in the spleen and cystic and centrilobular degeneration and necrosis of the liver. Neoplasms attributed to 3,3'-dimethoxybenzidine dihydrochloride exposure were observed in rats at many tissue sites, including the skin, Zymbal gland, preputial and clitoral glands, oral cavity, small and large intestines, liver, brain, mesothelium, mammary gland, and uterus/cervix. The incidences of these neoplasms in male and female rats are given in the abstract summary table (see page 5 of the Technical Report). Genetic Toxicology: 3,3'-Dimethoxybenzidine was mutagenic in S. typhimurium strain TA100 with exogenous metabolic activation and in strain TA98 without activation; a weakly positive response was observed in strain TA1535 with metabolic activation. 3,3'-Dimethoxybenzidine induced sister chromatid exchanges and chromosomal aberrations in CHO cells with and without exogenous metabolic activation

    a tendency of increasing incidence of the cervix uteri precancer and cancer in women of reproductive age is noticed recently being related to the growth of number of the sexually-transmitted infections. The cervix uteri pathology incidence in women of fertile age is 20-25%. to study the specific features of the cytological and colposcopical pattern in pregnant patients with benign cervix uteri pathology in the anamnesis and the character of its change post partum. we have examined 195 women during their pregnancy and 3-5 months post partum. All pregnant women, alongside with generally accepted clinical and laboratory examinations, were subjected to the simple and extended colposcopy, cytology of the targeted smears and, according to indications, the histological studies of bioptate. according to the results of the colcoscopical studies and the signs of the cervix uteri pathology found, the patients were divided into several groups. A control group included 49 pregnant women. The clinical and instrumental examination of 146 women with cervix uteri pathology has been carried out both during pregnancy and post partum. the structure of the clinical forms of benign and premalignant changes in the cervix uteri epithelium in pregnant patients has been found. Specific features of the cytological and colposcopical pattern in pregnant patients with benign cervix uteri pathology in anamnesis have been studied. The relationship between the parity of pregnancy, delivery, route of delivery and regress of both benign and premalignant changes in the cervix uteri epithelium 3-5 months post partum has been determined.

    We performed 17 intraarterial scintigraphies in six patients with recurrent cervix cancer. With Seldinger method, the agent (four different radiopharmaceuticals) was perfused at the same speed of infusion of anticancer drugs (25 cc/hour) through internal iliac artery. There were four different radiopharmaceuticals; 131 I-Lipiodol, 99m Tc(Technetium)-HSA (Human Serum Albumin), 99m Tc-Sucralfate and 99m Tc-MAA (Macroaggregated Albumin). We evaluate the distribution pattern of radioactivity by the use of ratio of Tumor/Extratumor uptake (T/ET ratio). Our results reveals that 99m Tc-MAA scan showed the highest T/ET ratio and the other were not ideal agents for intraarterial therapy of recurrent cervix cancer. In conclusion, an ideal radioisotope and tracer which can block capillary, for example MAA, should be re-evaluated or produced in order to treat the patient with recurrent cervix cancer.

  12. Coexisting Malignant Melanoma and Blue Nevus of the Uterine Cervix: An Unusual Combination

    2012-01-01

    Full Text Available Malignant melanoma (MM and blue nevi of the uterine cervix are an extremely rare neoplasm, probably derived from embryologic migration of melanocytes from the neural crest. MM displays aggressive behavior with a poor prognosis. We report the case of a 76-year-old postmenopausal woman abnormal vaginal bleeding. She underwent a hysterectomy and bilateral salpingo-oophorectomy with paraaortic-iliac lymphadenectomy. Histopathological and immunohistochemical studies were consistent with the diagnosis of MM and blue nevi in the uterine cervix. Although it is extremely rare, this case suggests that MM of the uterine cervix should be considered in the differential diagnosis of undifferentiated neoplasm. Early diagnosis is essential in order to warrant a better prognosis, although there are no cases of cure described.

    Full Text Available Isolated skeletal metastasis to the bony calvarium is extremely rare in patients with squamous cell carcinoma of the uterine cervix. We describe the clinical and imaging findings in a case of squamous cell carcinoma of the uterine cervix with metastases tothe bony calvarium as the sole site of metastasis. The patient was a 65-year-old woman with squamous cell carcinoma of the uterine cervix, FIGO stage IIIb, whose initial treatement was chemoradiation therapy. After 22 sessions of external-beam radiation,she developed headaches. On physical examination she had skull bone tenderness. On plain skull X-ray, there were osteolytic bony lesions. Brain MRI showed multiple enhancing skull bone metatstses. Eventually, a whole body bone scintigraphy revealed isolated diffuse increased activity in the bony calvarium. In the literature review, wefound only three similar cases of cervical cancer with scalp metastases and involvement of the bony calvarium.

    Treatment results for uterine cervix cancer were evaluated using a new concept named ''Effective Survival Rate''. This rate was calculated by subtracting the weighted sum of incidence rates of various complications from the 5-year survival rate. The numerical values for various complications were assigned as follows: surgical death, 1.0; severe complications, such as fistula ureterovaginalis and ileus, 0.5; mild complications, such as rectum and urinary bladder complications, 0.3 and 0.2. These values were determined with reference to the Karnofsky index of performance status. The effective survival rate was calculated for patients with satage 2 and 3 uterine cervix cancer treated by radiation therapy and surgery, and compared as a function of age between 30 and 70 years. We concluded that the effective survival rate was comparable for radiation therapy and surgery for stage 2 uterine cervix cancer. However, in patients with stage 3, radiation therapy was superior.

    It is unknown how initial cervix location and cervical support resistance to traction, which we term "apical support stiffness," compare in women with different patterns of pelvic organ support. Defining a normal range of apical support stiffness is important to better understand the pathophysiology of apical support loss. The aims of our study were to determine whether: (1) women with normal apical support on clinic Pelvic Organ Prolapse Quantification, but with vaginal wall prolapse (cystocele and/or rectocele), have the same intraoperative cervix location and apical support stiffness as women with normal pelvic support; and (2) all women with apical prolapse have abnormal intraoperative cervix location and apical support stiffness. A third objective was to identify clinical and biomechanical factors independently associated with clinic Pelvic Organ Prolapse Quantification point C. We conducted an observational study of women with a full spectrum of pelvic organ support scheduled to undergo gynecologic surgery. All women underwent a preoperative clinic examination, including Pelvic Organ Prolapse Quantification. Cervix starting location and the resistance (stiffness) of its supports to being moved steadily in the direction of a traction force that increased from 0-18 N was measured intraoperatively using a computer-controlled servoactuator device. Women were divided into 3 groups for analysis according to their pelvic support as classified using the clinic Pelvic Organ Prolapse Quantification: (1) "normal/normal" was women with normal apical (C -5 cm and Ba and/or Bp ≥ 0 cm). Demographics, intraoperative cervix locations, and apical support stiffness values were then compared. Normal range of cervix location during clinic examination and operative testing was defined by the total range of values observed in the normal/normal group. The proportion of women in each group with cervix locations within and outside the normal range was determined. Linear regression

    Ninety-one patients with carcinoma of the cervix received radical radiation therapy from May 1981 through August 1983 at NIRS hospital. The correlation between eight CT findings and the prognosis was analysed in 75 patients, performed CT scan within 15 days form the admision. Among these CT findings, area of uterine cervix correlates well with recurrence, and enlargement of para-aortic lymph nodes showed the strong correlation between metastasis. We also analized these data by a multivariate analytical method (quantification method II). There exists a correlation between the prognosis and the score of quantification method II, and this score will be a good index of the prognosis of patients with carcinoma of the cervix. (author)

    Elimination of types 16 and 18 human papilloma virus from the surface of cervix uteri for secondary prevention of cervical cancer was evaluated. The method is protected by patent of invention of the Russian Federation. Infrared laser therapy of cervix uteri was carried out in patients with precancer diseases of cervix uteri at Department of Gynecology of Municipal Clinical Hospital No. 52 (Moscow). Papillomavirus infection was eliminated using a Russian diode laser (lambda=1.06 μ, radiation power 10 W) with a collimating headpiece using carbon die at a distance of 10-12 cm from the exposed surface. The treatment resulted in a high percentage of elimination of types 16 and 18 oncogenic virus 4-6 weeks and during delayed periods after exposure.

    Malignant mixed mullerian tumors (MMMTs) are a rare uterine tumor and contribute to approximately 1-3% of all corpus malignant tumors. MMMTs are usually in the uterine corpus, but can also arise from the uterine cervix, vagina, ovaries and fallofian tubes. MMMTs of the uterine cervix are extremely rare. MMMTs are highly malignant and tend to maintain a rapid growth and exhibit a high rate of recurrence. Therefore, the prognosis of patients diagnosed with these types of tumors is extremely poor. We report a rare case of a malignant mixed mullerian tumor arising from the uterine cervix and introduce CT and MRI findings. CT and magnetic resonance findings of the uterine cervical MMMT in our case show highly aggressive features, such as parametrial involvement, pelvic and paraaortic lymphadenopathy, and distant metastasis and high enhancement

  19. Locally advanced cervix carcinoma - innovation in combined modality therapy

    Swift, Patrick S.

    1996-01-01

    Locally advanced cervical carcinoma continues to be a challenge to the clinician due to local failure as well as systemic metastases. Standard intracavitary and external beam techniques result in local control rates of only 35-65%, with long term survival rates of 25-60% in patients with state IIIA-IVA disease, indicating the need to identify new treatment strategies. Optimization programs for remote-afterloading interstitial brachytherapy allow the delivery of higher local doses of radiation to volumes that more closely approximate tumor target volumes as identified on MR scans, leading to improved therapeutic ratios. Identification of subsets of patients more likely to fail standard therapy, either locally or systemically, may be possible through such techniques as in vivo measurements of hypoxia with Eppendorf oxygen electrodes, interstitial fluid pressure measurements, the Comet assay, and nitroimidazole binding methods. Traditional chemotherapies, administered in either a neoadjuvant role or concomitantly with radiation have been disappointing in prospective trials. A variety of new agents are being investigated to determine if they can increase the frequency or duration of complete response. The taxanes, with response rates of 17-23% by themselves, are being assessed as potential radiosensitizers. The camptotheicin CRT-11 (Irinotecan) has demonstrated activity in platinum resistant cervix cancer, with response rates of 24%. Bioradiotherapeutic approaches, using 13-cis-retinoic acid and interferon-2a, are undergoing phase II studies. Neoangiogenesis inhibitors and vaccines against HPV are also being examined. The aggressive pursuit of techniques that help identify those patients most likely to fail, that allow the delivery of higher radiation doses more safely to the target volume, and that incorporate the use of more effective systemic therapies is necessary to improve the outcome for this disease

    This study evaluated early bowel complications in cervix cancer patients, following external radiotherapy (ERT) and high dose rate intracavitary radiation (HDR ICR). Factors affecting the risk of developing early bowel complications and its incidence are analyzed and discussed. The study is the retrospective review of 66 patients who received radiotherapy at Chungbuk National University Hospital from April 1994 to December 1998. The patients underwent 41.4 or 50.4 Gy ERT according to FIGO stage and tumor size, then A point dose was boosted to 71.4 or 74.4 Gy using a remotely controlled after loading Buchler HDR ICR. The EORTC/RTOG morbidity criteria were used to grade early bowel complications, which are valid from day 1, the commencement of therapy, through day 90. The actuarial incidence, severity of complications were investigated and clinical pretreatment factors relevant to complications were found through univariate (Wilcoxon) and multivariate (Cox proportional hazard model) analysis. Of the 66 patients, 30 patients (46%) developed early bowel complications; 25 patients (38%) with grade 1 or 2, 4 patients (6%) with grade 3 and 1 patient (2%) with grade 4. The complications usually began to occur 3 weeks after the commencement of radiotherapy. The actuarial incidence of early bowel complications was 41% at 10 weeks. The early bowel complications were associated significantly with an old age and a history of previous abdomino-pelvic surgery. All three patients who had a protracted overall treatment time (about 2 weeks) due to severe bowel complication, suffered from pelvic recurrences. Forty six percent of patients experienced early bowel complications, most of which were grade 1 or 2 and relieved spontaneously or by medication. The patients with an old age or a previous surgery have a high probability of early complications and they may be less compliant with planned radiotherapy. So more careful precaution is necessary for these patients

    Troglitazone (TRO) is a peroxisome proliferator-activated receptor γ (PPARγ ) agonist. TRO has antiproliferative activity on many kinds of cancer cells via G1 arrest. TRO also increases Cu 2+ /Zn 2+ -superoxide dismutase (CuZnSOD) and catalase. Cell cycle, and SOD and catalase may affect on radiation sensitivity. We investigated the effect of TRO on radiation sensitivity in cancer cells in vitro. Three human cervix cancer cell lines (HeLa, Me180, and SiHa) were used. The protein expressions of SOD and catalase, and catalase activities were measured at 2-10 μM of TRO for 24 hours. Cell cycle was evaluated with flow cytometry. Reactive oxygen species (ROS) was measured using 2',7'-dichlorofluorescin diacetate. Cell survival by radiation was measured with clonogenic assay. By 5 μM TRO for 24 hours, the mRNA, protein expression and activity of catalase were increased in all three cell lines. G0- G1 phase cells were increased in HeLa and Me180 by 5 μM TRO for 24 hours, but those were not increased in SiHa. By pretreatment with 5 μM TRO radiation sensitivity was increased in HeLa and Me180, but it was decreased in SiHa. In Me180, with 2 μM TRO which increased catalase but not increased G0-G1 cells, radiosensitization was not observed. ROS produced by radiation was decreased with TRO. TRO increases radiation sensitivity through G0-G1 arrest or decreases radiation sensitivity through catalasemediated ROS scavenging according to TRO dose or cell types. The change of radiation sensitivity by combined with TRO is not dependent on the PPAR γ expression level.

    Full Text Available BACKGROUND Neoplastic lesions of uterine cervix is one of the most common malignant neoplasms in women. The tremendous success in giving a confirmed diagnosis of the disease by doing histopathological examination is of prime importance in giving the most appropriate treatment and to understand the prognosis. The aim of the study is to study the incidence and age-wise distribution of the neoplastic lesions of the uterine cervix in peri and postmenopausal women by doing histopathological examination of neoplastic lesions and by doing correlation of clinical findings with histopathological examination. MATERIALS AND METHODS The study included 803 cases of total cervical specimens, out of which 180 cases of neoplastic cervical lesions were found, out of which 150 cases were found in the peri and postmenopausal age groups, i.e. above 40 years of age. The study was done in Gauhati Medical College and Hospital, Guwahati, from the period 1 st June, 2013, to 1 st June, 2014. The specimens that were included in the study were punch biopsies, hysterectomies and polypectomies and cervical specimens were studied by doing histopathological examinations. RESULTS Out of the 150 cases of neoplastic lesions in the peri and postmenopausal women, the most common neoplastic lesion was cervical intraepithelial neoplasia, i.e. CIN (8.3% of the cervix, followed by malignant (5.6% and benign (4.7% lesions of the cervix in this study group of patients. CONCLUSION Histopathological examination of the cervix is an effective method of giving a confirmed diagnosis of all the noncancerous, precancerous and cancerous lesions of uterine cervix, which helps in giving the most appropriate treatment and also helps in understanding the prognosis.

    the paper presents a rare case of metachronous gastric metastasis of uterine cervix cancer, clinically manifested through severe pyloric stenosis. 49-year-old patient, operated on in January 2009, with uterine cervix cancer (Squamous cell carcinoma T2bN1M0), is hospitalized in August 2011 with pyloric stenosis: epigastric pains, abundant, stasis, late postprandial emesis, significant weight loss, stomach form visible upon abdomen inspection. Endoscopy: antral stenosis with intact gastric mucosa, and CT-scan: circumferential intramural gastric tumor, stomach dilated in the upper part, lack of cleavage between the tumor and the liver bed of the gall bladder. CEA increased to 13,78 (below 5), CA 19-9 slightly increased 29.9 (below 27). The case is considered as a second neoplasia and a D2 subtotal gastrectomy was performed, with 1 positive ganglion out of 27 on block with atypical hepatectomy of segments 4-5 for liver invasion, the final mounting being Y Roux. The histopathological examination shows a gastric metastasis of squamous carcinoma, of uterine cervix origin, the invaded perigastric ganglion having the same aspect of uterine cervix carcinoma. The post-surgery evolution was favorable, under chemo radiotherapy the patient being alive without relapse at 9 months post-surgery. In the literature there are 2 more cases of gastric metastasis of uterine cervix carcinoma, and 4 of uterine carcinoma without topographic indication, but without the histological documentation of the tumor filiation, without data related to resecability or follow-up, the case at hand being, from this perspective, the first documented resectable metachronous gastric metastasis from a cervix uteri carcinoma.

    Preterm birth is the legal first global cause of neonatal death. The cervix has two roles: it has to stay closed to allow the fetus to undergo a normal development during gestation, and at term, the cervix has to dilate under the pressure of uterine contractions to allow the delivery. The purpose of this article is to establish if the ultrasound measured length of the cervix and its appearance are predictive for the spontaneous preterm birth. Cervical insufficiency can be described by painless cervical dilatation leading to pregnancy losses/ births, with no other risk factors present. During gestation, the physiological softening of the cervix is determined by the extracellular matrix components, particular decorin, and thrombospondin 2. The direction of the collagen fibers remains the same - circumferential direction, but the collagen solubility increases. Therefore, during pregnancy, the cervical tissue is more hydrated and has higher collagen extractability than non-pregnant tissue. Women with cervical incompetence have increased levels of smooth muscle cells than normal pregnant women, the number of elastic fibers is low, and also the concentration of hydroxyproline is decreased. Transvaginal ultrasound is the suitable gold standard exam that can offer essential information about the cervical length and state of the internal os in early asymptomatic stage of cervical insufficiency for predicting and preventing preterm birth. In our experience, a transvaginal ultrasound screening for the measurement of the cervix is required. We consider that the proper gestational age for the prediction of a preterm birth is at 18-22 weeks of gestation for the general population and earlier for patients with a history of preterm birth. Just from an observational point of view, we concluded with the fact that the cerclage of the cervix is unnecessary if the cervical length is above 2 cm and if the internal cervical os is closed. In the absence of funneling, the probability of

    ABSTRACT Remodeling of the cervix is a critical early component of parturition and resembles an inflammatory process. Infiltration and activation of myeloid immune cells along with production of proinflammatory mediators and proteolytic enzymes are hypothesized to regulate cervical remodeling as pregnancy nears term. The present study standardized an approach to assess resident populations of immune cells and phenotypic markers of functional activities related to the mechanism of extracellular matrix degradation in the cervix in preparation for birth. Analysis of cells from the dispersed cervix of mice that were nonpregnant or pregnant (Days 15 and 18 postbreeding) by multicolor flow cytometry indicated increased total cell numbers with pregnancy as well as increased numbers of macrophages, the predominant myeloid cell, by Day 18, the day before birth. The number of activated macrophages involved in matrix metalloproteinase induction (CD147) and signaling for matrix adhesion (CD169) significantly increased by the day before birth. Expression of the adhesion markers CD54 and CD11b by macrophages decreased in the cervix by Day 18 versus that on Day 15 or in nonpregnant mice. The census of cells that expressed the migration marker CD62L was unaffected by pregnancy. The data suggest that remodeling of the cervix at term in mice is associated with recruitment and selective activation of macrophages that promote extracellular matrix degradation. Indices of immigration and activities by macrophages may thus serve as markers for local immune cell activity that is critical for ripening of the cervix in the final common mechanism for parturition at term.

    Cervical cancer is rare in the pediatric population. In cases of cervical cancer, adenocarcinoma is predominantly reported. Clear cell adenocarcinoma (CCAC) of the uterine cervix is a very rare tumor and accounts for only 4% of all adenocarcinomas of the uterine cervix. Risk factors and pathogenesis of this disease are not exactly revealed. The intrauterine exposure to diethylstilbestrol (DES) and associated non-steroidal estrogen during pregnancy before 18 weeks is the only known risk factor. This study reports the imaging finding of primary uterine cervical tumor in a 15-year-old girl, who was finally diagnosed with CCAC, with no maternal history of DES exposure in utero.

This study reports the imaging finding of primary uterine cervical tumor in a 15-year-old girl, who was finally diagnosed with CCAC, with no maternal history of DES exposure in utero.

    External irradiation and brachytherapy are curative in the treatment of carcinoma of the cervix. The aim of radiotherapy is to optimize the irradiation of the target volume and to optimize the irradiation of the target volume and to reduce the dose to critical organs. The use of imaging (computed tomography and magnetic resonance imaging (computed tomography and magnetic resonance imaging added to clinical findings and standard guidelines) are studied in the treatment planning of external irradiation and brachytherapy in carcinoma of the cervix. Imaging allows an individualized and conformal treatment planning. (author)

    The aim of this pictorial review was to illustrate the normal cervix appearance on T2-weighted images, and give a review of common or less common disorders of the uterine cervix that appear as high signal intensity lesions on T2-weighted sequences. Numerous aetiologies dominated by cervical cancer are reviewed and discussed. This gamut is obviously incomplete; however, radiologists who perform MR women's imaging should perform T2-weighted sequences in the sagittal plane regardless of the indication for pelvic MR. Those sequences will diagnose some previously unknown cervical cancers as well as many other unknown cervical or uterine lesions. (orig.)

    One of the most important prognostic features of early cervix cancer is the involvement of regional lymph nodes (LN). Although not fully studied, the sentinel node (SN) strategy has the potential of preventing unnecessary extensive LN dissections in these patients. The aim of this study was to determine the feasibility of SN identification by means of preoperative lymphoscintigraphy (PL) and intraoperative gamma probe detection (IGPD) in patients undergoing radical hysterectomy and pelvic/para-aortic lymphadenectomy for the treatment of early cervix carcinoma.

    We sought to evaluate a recently proposed protocol whereby transabdominal ultrasound of the cervix might be used as a prescreen to select women to undergo or to forgo measurement of cervical length via transvaginal ultrasound (CLvag). This was a prospective cohort study. Measurements of cervical length via transabdominal ultrasound (CLabd) and CLvag were made in women with singleton pregnancy during routine obstetrical ultrasound examination at 18(0/7) to 23(6/7) weeks of gestation. The transabdominal screen was considered positive if CLabd was ≤36 mm with the maternal bladder full or ≤35 mm with the bladder empty, or adequate imaging of the cervix could not be obtained. Sensitivity, specificity, predictive values, and likelihood ratios of a positive screen to detect a short cervix (CLvag ≤25 mm) were calculated. An interim analysis identified several technical problems with CLabd measurements, so the protocol was extensively revised. Under the revised protocol, 1580 women were included. Adequate views of the cervix were obtained via transabdominal imaging in 46% of subjects with the bladder empty and 56% with the bladder full. The correlation between CLabd and CLvag was poor (r = 0.38). Of the 17 patients with a short cervix, 15 had suboptimal transabdominal exams (screen positive) and 2 had CLabd ≤35 mm with bladder empty (screen positive). Sensitivity of the screen was 100% (95% confidence interval, 80.5-100%) but specificity was only 32.2% (95% confidence interval, 29.9-34.6%) and screen positive rate was 66.3%. Several technical problems and limitations of transabdominal imaging of the cervix are shown. Using modern, high-resolution ultrasound equipment, we were unable to adequately image the cervix via transabdominal ultrasound in half the cases. Although we confirmed that a CLabd cutoff value of 35-36 mm is appropriate for detection of short cervix, the technique for measuring CLabd is fraught with technical problems.

    Full Text Available Abstract Background In the mouse uterus, pregnancy is accompanied by changes in tachykinin and tachykinin receptor gene expression and in the uterotonic effects of endogenous tachykinins. In this study we have investigated whether changes in tachykinin expression and responses are a result of changes in ovarian steroid levels. Methods We quantified the mRNAs of tachykinins and tachykinin receptors in uteri from ovariectomized mice and studied their regulation in response to estrogen and progesterone using real-time quantitative RT-PCR. Early (3 h and late (24 h responses to estrogen were evaluated and the participation of the estrogen receptors (ER, ERalpha and ERbeta, was analyzed by treating mice with propylpyrazole triol, a selective ERalpha agonist, or diarylpropionitrile, a selective agonist of ERbeta. Results All genes encoding tachykinins (Tac1, Tac2 and Tac4 and tachykinin receptors (Tacr1, Tacr2 and Tacr3 were expressed in uteri from ovariectomized mice. Estrogen increased Tac1 and Tacr1 mRNA after 3 h and decreased Tac1 and Tac4 expression after 24 h. Tac2 and Tacr3 mRNA levels were decreased by estrogen at both 3 and 24 h. Most effects of estrogen were also observed in animals treated with propylpyrazole triol. Progesterone treatment increased the levels of Tac2. Conclusion These results show that the expression of tachykinins and their receptors in the mouse uterus is tightly and differentially regulated by ovarian steroids. Estrogen effects are mainly mediated by ERalpha supporting an essential role for this estrogen receptor in the regulation of the tachykinergic system in the mouse uterus.

    Good knowledge of physiological 18 F-fluorodeoxglucose ( 18 F-FDG) uptake in the healthy population is of great importance for the correct interpretation of 18 F-FDG positron emission tomography (PET) images of pathological processes. The purpose of this study was to investigate the physiological 18 F-FDG uptake in the ovaries and uterus of healthy female volunteers. One hundred and 33 healthy females, 78 of whom were premenopausal (age 37.2±6.9 years) and 55 postmenopausal (age 55.0±2.7 years), were examined using whole-body 18 F-FDG PET and pelvic magnetic resonance (MR) imaging. Focal 18 F-FDG uptake in the ovaries and uterus was evaluated visually and using standardised uptake value (SUVs). Anatomical and morphological information was obtained from MR images. Distinct ovarian 18 F-FDG uptake with an SUV of 3.9±0.7 was observed in 26 premenopausal women out of 32 examined during the late follicular to early luteal phase of the menstrual cycle. Eighteen of the 32 women also showed focal 18 F-FDG uptake in the endometrium, with an SUV of 3.3±0.3. On the other hand, all nine women in the first 3 days of the menstrual cycle demonstrated intense 18 F-FDG uptake in the endometrium, with an SUV of 4.6±1.0. No physiological 18 F-FDG uptake was observed in the ovaries or uterus of any postmenopausal women. In women of reproductive age, 18 F-FDG imaging should preferably be done within a week before or a few days after the menstrual flow phase to avoid any misinterpretation of pelvic 18 F-FDG PET images.

    ABSTRACT E-cadherin (CDH1) is a cell adhesion molecule that coordinates key morphogenetic processes regulating cell growth, cell proliferation, and apoptosis. Loss of CDH1 is a trademark of the cellular event epithelial to mesenchymal transition, which increases the metastatic potential of malignant cells. PTEN is a tumor-suppressor gene commonly mutated in many human cancers, including endometrial cancer. In the mouse uterus, ablation of Pten induces epithelial hyperplasia, leading to endometrial carcinomas. However, loss of Pten alone does not affect longevity until around 5 mo. Similarly, conditional ablation of Cdh1 alone does not predispose mice to cancer. In this study, we characterized the impact of dual Cdh1 and Pten ablation (Cdh1d/d Ptend/d) in the mouse uterus. We observed that Cdh1d/d Ptend/d mice died at Postnatal Days 15–19 with massive blood loss. Their uteri were abnormally structured with curly horns, disorganized epithelial structure, and increased cell proliferation. Co-immunostaining of KRT8 and ACTA2 showed invasion of epithelial cells into the myometrium. Further, the uteri of Cdh1d/d Ptend/d mice had prevalent vascularization in both the endometrium and myometrium. We also observed reduced expression of estrogen and progesterone receptors, loss of cell adherens, and tight junction molecules (CTNNB1 and claudin), as well as activation of AKT in the uteri of Cdh1d/d Ptend/d mice. However, complex hyperplasia was not found in the uteri of Cdh1d/d Ptend/d mice. Collectively, these findings suggest that ablation of Pten with Cdh1 in the uterus accelerates cellular invasiveness and angiogenesis and causes early death. PMID:23740945

    The objective was to elucidate gene expression differences in uterus, caruncle, and cotyledon of ewes with subclinical pregnancy toxemia (SCPT) and healthy ewes, and to identify associated biological functions and pathways involved in pregnancy toxemia. On Day 136 (±1 day) post-breeding, ewes (n = 18) had body condition score (BCS; 1-5; 1, emaciated; 5, obese) assessed, and blood samples were collected for plasma glucose and β-hydroxybutyrate (BHBA) analyses. The ewes were euthanized, and tissue samples were collected from the gravid uterus and placentomes. Based on BCS (2.0 ± 0.02), glucose (2.4 ± 0.33), and BHBA (0.97 ± 0.06) concentrations, ewes (n = 10) were grouped as healthy (n = 5) and subclinical SCPT (n = 5) ewes. The mRNA expressions were determined by quantitative PCR method, and prediction of miRNA partners and target genes for the predicted miRNA were identified using miRDB (http://mirdb.org/miRDB/). Top ranked target genes were used to identify associated biological functions and pathways in response to SPCT using PANTHER. The angiogenesis genes VEGF and PlGF, and AdipoQ, AdipoR2, PPARG, LEP, IGF1, IGF2, IL1b, and TNFα mRNA expressions were lower in abundances, whereas hypoxia genes eNOS, HIF1a, and HIF 2a, and sFlt1 and KDR mRNA expressions were greater in abundances in uterus and placenta of SCPT ewes compared to healthy ewes (P influence placental vascular development and angiogenesis as noted in this study set the course for hemodynamic changes and hence have a major impact on the rate of transplacental nutrient exchange, fetal growth, and health of the dam.

    Autoradiographic studies of labeled steroid uptake in mouse uterine tissue indicated that labeled estradiol was predominantly sequestered in the nuclei of stromal and glandular epithelial cells at 1 h. Luminal epithelial cells did not show appreciable nuclear accumulation of labeled estradiol until 7-8 h after hormone injection. Studies using non-target tissues and unlabeled steroids indicated that the nuclear uptake events were tissue and estrogen steroid specific. The temporal pattern of steroid hormone uptake in the uterus would suggest that an initial interaction in stromal and glandular epithelial cells may be required prior to nuclear stimulation in the luminal epithelial target cell

    An LiF dosimeter placed inside the uterus will only give an approximate value of the dose delivered to gonads during therapy by iodine-131. But it was easily demonstrated that the dose measured by LTD dosimeter does not significantly differ for uterus and for ovaries, because of the similar position of the source organs. Consequently a LiF dosimeter was placed in volunteer patients inside the uterus. Experimental results were compared to the dose calculated by Robertson and Gorman (J. Nucl. Med. 17, 826, (1976)) method for ovaries and for uterus. (author)

    The purpose of this study is to examine the morphological and kinematical changes of the uterus induced by electrical stimulation applied to the skin just above the second and fourth posterior sacral foramens (sacral surface electrical stimulation [ssES]) in 26 healthy subjects. Out of them, eight subjects who had severe pain subjectively during every menstruation received ssES just in menstruation. Morphological and functional changes of the uterus were examined by using T2-weighted magnetic resonance (MR) imaging and T1-weighted MR cinematography, respectively. Cyclic electrical stimulation for 15 min with 5 sec ON and 5 sec OFF was applied just before MR scanning. A decrease in thickness of the muscular layer of the uterus was observed in every subject after ssES for 15 min and was significant as compared with the thickness before ssES. Periodic uterine movement during menstruation was observed in the subjects with severe menstrual pain in MR cine and the power spectrum analysis of the movement showed a marked decrease in peak power and frequency after ssES treatment. We conclude that ssES causes a reduction of static muscle tension of the uterus in all menstrual cycle periods and suppression of uterine peristalsis during menstruation in the subjects with severe menstrual pain. Possible neural mechanisms for these static and dynamic effects of ssES on the uterus at spinal level are discussed. (author)

    The sine oculis homeobox 1 (SIX1) is a member of the Six gene family. SIX1 is involved in tissue development by regulating proliferation, apoptosis, and differentiation. However, function of SIX1 in the uterus remains unknown. Here, we found that Six1 expression is regulated along the estrous cycle in mouse uterus. Six1 expression was significantly increased at estrus stage and decreased at the rest of stages. SIX1 is detected in the luminal and glandular epithelium of uterine endometrium at the estrus stage. Estrogen injection increased Six1 expression in the ovariectomized mouse uterus, whereas progesterone had no effect on its expression. Estrogen receptor antagonist inhibited estrogen-induced Six1 expression. Our findings imply that SIX1 may play a role as an important regulator to orchestrate the dynamic of uterine endometrium in response to estrogen level during the estrous cycle. These results will give us a better understanding of uterine biology. - Highlights: • Six1 expression is regulated during the estrous cycle in mouse uterus. • Six1 is highly expressed at the estrus stage of estrous cycle. • SIX1 is detected in luminal/glandular epithelium of the uterus at the estrus stage. • Estrogen stimulates Six1 expression in an estrogen receptor-dependent manner.

    Two groups of uterus tumors (benign and malignant) postmenopausal patients were used to investigate the presence of prostate specific antigen (PSA). Preliminary experiments were performed to follow the binding of '1 25 I-anti total PSA antibody with PSA in uterus tissues homogenates of the two groups with their corresponding antigen and found to be (8.8,7.1%) for benign and malignant tumors, respectively. An Immuno Radio Metric Assay (IRMA) procedure was developed for measuring PSA in benign and malignant uterus tumors homogenates. The optimum conditions of the binding of 125 I-anti total PSA antibody with PSA were as follows: PSA concentration (150,200 μg protein),tracer antibody concentration (125,250 μg protein), p H (7.6,7.2), temp (15,25?C) and time (1.5 hrs) for postmenopausal benign and malignant uterus tumors tissue homogenates, respectively. The use of different concentrations of Na + and Mg 2+ ions were shown to cause an increase in the binding at concentration of (125,75 mΜ) of Na 1+ ions (75,225 mΜ) of Mg 2+ ions for benign and malignant uterus tumors homogenates, respectively, while the use of different concentrations of urea and polyethylene glycol (PEG) Caused a decrease in the binding with the increase in the concentration of each of urea and PEG in the both cases

    To observe the effect of Cuichan Zhusheng Decoction (CZD) on cervical maturation factors. Ninety women with full-term pregnancy and indication for labor inducing were assigned to three groups equally. The treated group was treated by water decoction of CZD, one dose (300 mL) daily, taken orally in the morning 30 min before breakfast, for successive 3 days, the administration would be discontinued if uterine contraction occurred for over 3 times/hour in the course. The control group was treated with pitocin by adding 1 U into 500 mL 5% glucose for intravenous dripping in 6 h, once every day for 3 successive days. The blank group was treated by placebo of CZD, administrated in same way as that in the treated group. The length and width of cervix and diameter of neck tube in all the women were measured on the very day of medication and 72 h later or parturient time by vaginal B-ultrasonography, and the cervical maturation degree was scored referring to the clinical Bishop scale. In the experimental study, the cervical tension of pregnant rats was measured with an in vitro cervical tension-meter, rats' cervical tissues were taken for pathologic examination to observe its morphological change. The total effective rate for promoting cervical maturation was 96.67% in the treated group and 83.33% in the control group. It was significantly superior in the treated group to that in the control group and the blank group (Pcongestion with massive amount of inflammatory cells infiltration, increased matrix components, and many leucocyte and fibroblast in the stroma could be seen. CZD can change the morphorlogic structure of cervical tissue, decrease cervical tension, so as to promote the cervical maturation and induce labor.

    This study was undertaken to evaluate the efficacy of postoperative radiotherapy, and to investigate the prognostic factors for FIGO stages IB-IIB cervical cancer patients who were treated with simple hysterectomy, or who had high-risk factors following radical hysterectomy and pelvic lymph node dissection. Between March 1986 and December 1998, 58 patients, with FIGO stages IB-IIB cervical cancer were included in this study, The indications for postoperative radiation therapy were based on the pathological findings, including lymph node metastasis, positive surgical margin, parametrial extension, Iymphovascular invasion, invasion of more than half the cervical stroma, uterine extension and the incidental finding of cervix cancer following simple hysterectomy. All patients received external pelvic radiotherapy, and 5 patients, received an additional intracavitary radiation therapy. The radiation dose from the external beam to the whole pelvis was 45 - 50 Gy. Vagina cuff irradiation was performed, after completion of the external beam irradiation, al a low-dose rate of CS-137, with the total dose of 4488-4932 chy (median: 4500 chy) at 5 mm depth from the vagina surface. The median follow-up period was 44 months (15-108 months), The 5-yr actuarial local control rate, distant free survival and disease-free survival rate were 98%, 95% and 94%, respectively. A univariate analysis of the clinical and pathological parameters revealed that the clinical stage (p=0.0145), status of vaginal resection margin (p=0.0002) and parametrial extension (p=0.0001) affected the disease-free survival. From a multivariate analysis, only a parametrial extension independently influenced the disease-free survival. Five patients (9%) experienced Grade 2 late treatment-related complications, such as radiation proctitis (1 patient), cystitis (3 patients) and lymphedema of the leg (1 patient). No patient had grade 3 or 4 complications. Our results indicate that postoperative radiation therapy can

    Embryonic diapause is a reproductive strategy widespread in the animal kingdom. This phenomenon is defined by a temporary arrest in blastocyst growth and metabolic activity within a quiescent uterus without implantation until the environmental and maternal milieu become favorable for pregnancy to progress. We found that uterine Msx expression persists during diapause across species; their inactivation in the mouse uterus results in termination of diapause with the development of implantation-like responses (“pseudoimplantation”) that ultimately succumbed to resorption. To understand the cause of this failure, we compared proteome profiles between floxed and Msx-deleted uteri. In deleted uteri, several functional networks, including transcription/translation, ubiquitin-proteasome, inflammation, and endoplasmic reticulum stress, were dysregulated. Computational modeling predicted intersection of these pathways on an enhanced inflammatory signature. Further studies showed that this signature was reflected in increased phosphorylated IκB levels and nuclear NFκB in deleted uteri. This was associated with enhanced proteasome activity and endoplasmic reticulum stress. Interestingly, treatment with anti-inflammatory glucocorticoid (dexamethasone) reduced the inflammatory signature with improvement of the diapause phenotype. These findings highlight an unexpected role of uterine Msx in limiting aberrant inflammatory responses to maintain embryonic diapause. PMID:25931120

    Cellular senescence, defined as an irreversible cell cycle arrest, exacerbates the tissue microenvironment. Our previous study demonstrated that mouse uterine senescent cells were physiologically increased according to gestational days and that their abnormal accumulation was linked to the onset of preterm delivery. We hypothesized that there is a mechanism for removal of senescent cells after parturition to maintain uterine function. In the current study, we noted abundant uterine senescent cells and their gradual disappearance in wild-type postpartum mice. F4/80+ macrophages were present specifically around the area rich in senescent cells. Depletion of macrophages in the postpartum mice using anti-F4/80 antibody enlarged the area of senescent cells in the uterus. We also found excessive uterine senescent cells and decreased second pregnancy success rate in a preterm birth model using uterine p53-deleted mice. Furthermore, a decrease in F4/80+ cells and an increase in CD11b+ cells with a senescence-associated inflammatory microenvironment were observed in the p53-deleted uterus, suggesting that uterine p53 deficiency affects distribution of the macrophage subpopulation, interferes with senescence clearance, and promotes senescence-induced inflammation. These findings indicate that the macrophage is a key player in the clearance of uterine senescent cells to maintain postpartum uterine function. Copyright © 2017 Endocrine Society.

    A survey of past case reports on radiation-induced cancer of the uterus was carried out with the main object of finding the lowest irradiation dose. Search of literature published since 1912 revealed 548 cases of radiation-induced cancer of the uterus. All of these cases of radiation-induced cancer had received radiation for the treatment of non-malignant disease. The primary gynecological conditions which were the object of radiation therapy were functional bleeding, endometrial hyperplasia, myoma, endometritis, and polyps. The lowest irradiation dose was estimated at 1000-1450 rad in the case of external X-ray irradiation, and 100 mg.hr for intrauterine radium therapy, which corresponds to 100-1000 rad. It was noted that were more cases of corpus cancer than cervical cancer. Histopathological findings of radiation-induced uterine cancer were carcinoma, sarcoma, and mixed mesodermal tumors. The latent period was distributed in the range of 1 to 40 years, with the average of 10.1 years. (auth.)

    Full Text Available Placenta accrete refers to an abnormality of placental implantation in which the anchoring placental villi attached to myometrium rather than decidua resulting in a morbidity adherent placenta. Placenta increta (chorionic villi penetrate into the myometrium and placenta percreta (chorionic villi penetrate through the myometrium to the uterine serosa or adjacent organs are related, but more severe, abnormalities of placental implantation. The pathogenesis is primarily attributed to defective decasualization of the implantation site. Placenta accreta has been recognized mostly in the third trimester however may also present in second trimester. It has very heavy, life-threatening hemorrhage to both the mother and fetus. The authors’ report a patient with two previous cesarean deliveries, who had been referred for pregnancy termination from Iranian legal medicine organization with 15 weeks of gestational age and placenta acctera. In this patient, uterus preservation and hysterectomy abortion was performed. The case totally lost 1500 cc blood and she was discharged from hospital two days later, with feeling of well- being. We have examined this patient after 1.5 months, she wasn’t vaginal bleeding and the uterus was in the pelvic and serum BHCG (with titer was negative.

    2014-03-01

    Full Text Available Deletion of the Heme Oxygenase-1 (Hmox1 locus in mice results in intrauterine lethality. The expression of the heme catabolyzing enzyme encoded by this gene, namely HO 1, is required to successfully support reproductive events. We have previously observed that HO-1 acts at several key events in reproduction ensuring pregnancy. HO-1 defines ovulation, positively influences implantation and placentation and ensures fetal growth and survival. Here, we embarked on a study aimed to determine whether hormonal changes during the estrous cycle in the mouse define HO-1 expression, thus influencing receptivity. We analyzed the serum levels of progesterone and estrogen by ELISA and HO-1 mRNA expression in uterus by real time RT-PCR at the metestrus, proestrus, estrus and diestrus phases of the estrous cycle. Further, we studied the HO-1 protein expression by Western Blot upon hormone addition to cultured uterine AN3 cells. We observed that HO-1 variations in uterine tissue correlated to changes in hormonal levels at different phases of the estrus cycle. In vitro, HO-1 protein levels in AN3 cells augmented after the addition of physiological concentrations of progesterone and estradiol, which confirmed our in vivo observations. Our data suggest an important role for hormones in HO-1 regulation in uterus that has a significant impact in receptivity and later on blastocyst implantation.

  13. Angiotensin peptides in the non-gravid uterus: Paracrine actions beyond circulation.

    The renin-angiotensin system (RAS) involves a complex network of precursors, peptides, enzymes and receptors comprising a systemic (endocrine) and a local (paracrine/autocrine) system. The local RAS plays important roles in tissue modulation and may operate independently of or in close interaction with the circulatory RAS, acting in a complementary fashion. Angiotensin (Ang) II, its receptor AT 1 and Ang-(1-7) expression in the endometrium vary with menstrual cycle, and stromal cell decidualization in vitro is accompanied by local synthesis of angiotensinogen and prorenin. Mas receptor is unlikely to undergo marked changes accompanying the cyclic ovarian steroid hormone fluctuations. Studies investigating the functional relevance of the RAS in the non-gravid uterus show a number of paracrine effects beyond circulation and suggest that RAS peptides may be involved in the pathophysiology of proliferative and fibrotic diseases. Endometrial cancer is associated with increased expression of Ang II, Ang-converting enzyme 1 and AT 1 in the tumoral tissue compared to neighboring non-neoplastic endometrium, and also with a gene polymorphism that enhances AT 1 signal. Ang II induces human endometrial cells to transdifferentiate into cells with myofibroblast phenotype and to synthetize extracellular matrix components that might contribute to endometrial fibrosis. Altogether, these findings point to a fully operating RAS within the uterus, but since many concepts rely on preliminary evidence further studies are needed to clarify the role of the local RAS in uterine physiology and pathophysiology.

    Full Text Available Primary malignant melanomas of uterine cervix are quite rarely seen neoplasms, and long-life prognosis of patients with this disease is poor. Immunohistochemical methods and exclusion of other primary melanoma sites are used to confirm the diagnosis. As with other melanomas, cervix malignant melanomas may also cause cardiac metastases. Cardiac metastases are among rarely seen but more commonly encountered cases, compared to primary cardiac tumors. Here, we present a case of biatrial cardiac metastases in a 73-year-old patient with uterine cervix malignant melanomas. The patient underwent echocardiography, cardiac magnetic resonance imaging, and computed tomography. Our report shows the importance of advanced diagnostic techniques, such as cardiac magnetic resonance, not only for the detection of cardiac masses, but for a better anatomic definition and tissue characterization. Although the cases of malignant melanomas leading to multiple cardiac metastasis were reported in literature, the metastatic concurrence of malignant melanomas in both right and left atriums is quite rarely encountered as metastatic malignant melanomas. Also, another intriguing point in our case is that the primary lesion of our case was stemmed from uterine cervix, but not skin.

    Purpose of the radio-therapy is maximize the radiation dose to the tumor while minimizing the dose to the critical organ. Carcinoma of the uterine cervix treatment are external irradiation or an interstitial brachytherapy make use of isotope. Brachytherapy is a method of radiotherapy in advantage to achieve better local control with minimum radiation toxicity in comparison with external irradiation because radiation dose is distributed according to the inverse square low of gamma-ray emitted from the implanted sources. Authors make use of the patients data which 192 Ir gives medical treatment intracavity. Intracavitary radiation of the uterine cervix cancer, critical organ take 20% below than exposure dose of A point in the ICRU report. None the less of the advice, Radiation proctitis and radiation cystitis are frequent and problematic early complications in patients treated with radiation for the uterine cervix cancer. In brachytherapy of uterine cervical cancer using a high dose rate remote afterloading system, it is of prime importance to deliver a accurate dose in each fractionated treatment by minimizing the difference between the pre-treatment planned and post-treatment calculated doses. Use of packing to reduce late complications intracavitary radiation of the uterine cervix cancer. Bladder and rectum changes exposure dose rate by radiotherapy make use of packing.

    Cervix cancer (UCC) is considered a sexually transmitted disease due to factors involved in its appearance and development and this infection is recognized as the main etiological agent of this entity. In Cuba this type of tumor is placed in 2nd category in incidence and in 4th place in mortality among the malignant disease affecting the female sex. The objective of present study is to determine the types of human virus papilloma (HVP) present in samples of cervix tumors in Cuban women, as well as to describe the behavior of different risk factors associated with this disease. Forty five samples of cervix cancer were analyzed and the presence of 20 types of HVP was determined by polymerase chain reaction with specific primers founding in them a 91,1% of positivity. Genotype 16 was the more prevalent, followed by the 18, 45, 31, 39, 51, 56, 59, PAP23A. The low risk type 6 and 11 weren't founded in samples. Promiscuity was the more interesting risk factor in our study. Knowledge of the viral types present in cervix cancer in our patients is very important when we approach the development and the use of prophylactic and therapeutical vaccines

  9. Clinical significance of shape of isodosecurves in intracavitary radiation therapy in carcinoma of the uterine cervix

    Higuchi, Tatsuo

    1985-01-01

    In intracavitary radiation therapy of carcinoma of the uterine cervix, deviated position of microsources in the uterine and vaginal cavities from standard position was classified as follows: (1) Slipped position of a whole system of microsources. (2) Slipped position of the uterine tandem. (3) Slipped position of the colpostat. (4) Anteversion-flexion position of the uterine tandem. (a) Anterior displacement of the vaginal colpostat. (b) Posterior displacement of the vaginal colpostat. (5) Retroversion-flexion position of the uterine tandem. (a) Posterior displacement of the vaginal colpostat. (b) Retroposed position of the uterine tandem. (6) Side inclination of the uterine tandem. In every position, dose distribution around microsources was calculated by computers and isodosecurves in the vicinity of the cervix were constructed in three dimensions. Advantage and disadvantage of shape of these isodosecurves were discussed clinically with special reference to dosage of the lesions, rectum and bladder which was delivered from microsources. Besides these studies we clarified the reason why adequate cancerocidal dosage of carcinoma of the uterine cervix in the aged was much less than in the younger on the basis of anatomical and tumor size difference between two groups. The similar difference could be found between Japanese and Westerns in radiation therapy of carcinoma of the uterine cervix. (author)

    2014-01-01

    Full Text Available Non-Hodgkin’s lymphoma of the cervix is an extremely uncommon entity, with no standard established treatment protocol. A 43-year-old asymptomatic female with a history of dual hit blastic B-cell lymphoma/leukemia in complete remission presented with an incidental cervical mass, which was initially felt to represent a cervical fibroid on computed tomography (CT. It was further evaluated with ultrasound, biopsy, and positron emission tomography-computed tomography (PET-CT, which demonstrated a growing biopsy-proven lymphomatous mass and new humeral head lesion. The patient was started on chemotherapy to control the newly diagnosed humeral head lesion, which then regressed. She then underwent radiation to the cervix with significant improvement in the cervical lymphoma. A review of cross-sectional imaging findings of lymphoma of the cervix is provided, including how to differentiate it from other more common diseases of the cervix. Clinical awareness of rare cervical masses such as lymphoma is very important in order to achieve timely diagnosis and appropriate treatment.

    Brachytherapy in the form of High Dose Rate (HDR) intracavitary radiotherapy (ICRT) along with external beam radiotherapy(EBRT) is the main treatment in cancer cervix. Of late, some large centres have started practicing template based transperineal interstitial brachytherapy (TIB) for advanced/ bulky cancer cervix. Usually, TIB is given for patients with advanced disease/ distorted anatomy or recurrent disease for better lateral target coverage. CT/MRI/USG based planning has made volumetric dosimetry possible for the target and the organs at risk (OARs). This has resulted in better correlation between dose received and treatment outcome in terms of tumour control and late toxicities as against the point dosimetry system. It has been shown by many studies that ICRU based point dose reporting may not represent the actual doses received by the OARs. Though it is expected that TIB gives better target coverage and OAR sparing in advanced/ bulky cancer cervix cases as compared to ICRT, detailed patient studies on the subject have not been reported. We have carried out dosimetric comparison between ICRT and TIB for cancer cervix patients undergoing treatment at our centre in terms of treated volume and doses to OARs

    Purpose: To assess the predictive value of pretreatment proliferative activity of epidermoid cervix carcinoma cells with respect to short- and long-term results of radiotherapy. Methods and Materials: The proliferative activity of 25 epidermoid cervix carcinomas was evaluated as the immunofluorescent labelling index (LI) by rabbit antithymidine antibodies reacting specifically with single-stranded DNA of replication forks in S-phase cells. The short-term clinical outcome was estimated at 3-6 months after treatment by visual and palpatory examination. Three-year follow-up data were obtained through hospital charts and correspondence with referring physicians for only 19 patients. Results: There was no statistically significant association between LI and such conventional prognostic factors as clinical stage. The LI value of cervix carcinomas was significantly associated with complete regression at 3-6 months after radiotherapy and 3-year disease-free survival. Complete regression at 3-6 months was observed in 87.5% patients with fast proliferating tumors (LI > 7.0%), and only in 41.2% patients with slowly proliferating tumors (p = 0.03). Probability of 3-year disease-free survival was 85.7% in patients with fast proliferating tumors and 50.0% in those with slowly proliferating tumors (p = 0.05). Conclusions: The immunofluorescent LI of epidermoid cervix carcinoma is able to provide prognostic information on short-term tumor response to radiotherapy and disease-free survival

    Martyn, F; McAuliffe, F M; Wingfield, M

    2014-10-10

    Knowledge regarding the role of the cervix in fertility has expanded considerably over the past 20 years and in this article, we propose that it is now time for its function to be reappraised. First, we review the anatomy of the cervix and the vaginal ecosystem that it inhabits. Then, we examine the physiology and the role of the cervical mucus. The ongoing mystery of the exact mechanism of the sperm-cervical mucus interaction is reviewed and the key players that may unlock this mystery in the future are discussed. The soluble and cellular biomarkers of the lower female genital tract which are slowly being defined by contemporary research are reviewed. Attempts to standardize these markers, in this milieu, are hindered by the changes that may be attributed to endogenous or exogenous factors such as: age, hormonal changes during the menstrual cycle, ectropion, infection, smoking and exposure to semen during sexual intercourse. We review what is known about the immunology of the cervix. With the widespread use of large loop excision of the transformation zone (LLETZ) for treatment of cervical intraepithelial neoplasia, the anatomy of the cervix is changing for many women. While LLETZ surgery has had very positive effects in the fight against cervical cancer, we debate the impact it could have on a woman's fertility. © The Author 2014.

    Preterm birth is the leading cause of perinatal morbidity and mortality worldwide, and is the most important challenge to modern obstetrics. A major obstacle has been that preterm birth is treated (implicitly or explicitly) as a single condition. Two-thirds of preterm births occur after the spontaneous onset of labor, and the remaining one-third after “indicated” preterm birth; however, the causes of spontaneous preterm labor and “indicated” preterm birth are different. Spontaneous preterm birth is a syndrome caused by multiple etiologies, one of which is a decline in progesterone action, which induces cervical ripening. A sonographic short cervix (identified in the midtrimester) is a powerful predictor of spontaneous preterm delivery. Randomized clinical trials and individual patient meta-analyses have shown that vaginal progesterone reduces the rate of preterm delivery at cervix, and therefore, the compound of choice is natural progesterone (not the synthetic progestin). Routine assessment of the risk of preterm birth with cervical ultrasound coupled with vaginal progesterone for women with a short cervix is cost-effective, and implementation of such a policy is urgently needed. Vaginal progesterone is as effective as cervical cerclage in reducing the rate of preterm delivery in women with a singleton gestation, history of preterm birth, and a short cervix (<25mm).

    Tritiated 17α-methylestradiol was synthesized to investigate the potential of the carbon-11-labeled analog as an estrogen-receptor-binding radiopharmaceutical. In vitro, 17α-methylestradiol is bound with high affinity to the cytoplasmic estrogen receptor from rabbit uterus (K/sub d/ = 1.96 x 10 -10 M), and it sediments as an 8S hormone-receptor complex in sucrose gradients. The compound shows specific uptake in the uterus of the adult rat, within 1 h after injection. In female rats bearing DMBA-induced tumors, specific uterine and tumor uptakes were observed, although at 30 min the tumor uptake was only 23 to 30% of the uptake in the uterus. Tritiated 17α-methylestradiol with a specific activity of 6 Ci/mmole showed a similar tissue distribution. Our results indicate that a 17 α-methylestradiol is promising as an estrogen-receptor-binding radiopharmaceutical

    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.

    We studied on scintigraphy for demonstration of primary site and infiltrating area of carcinoma of uterine cervix by using 111 In-BLM, which is drawing attention as one of the tumor-imaging agents. In 17 cases (77%) out of 22 cases of the carcinoma of uterine cervix, this scintigraphy demonstrated the primary site and the extent of infiltration into parametrium with distinctive positive images. Thus, this radiopharmaceutical was found to be of great use for determining the treatment of the carcinoma of uterine cervix. (author)
