    In the present study, we characterized the evoked electrical activity from T(13) to S(2) dorsal roots (DRs) during glass probe-stimulation of the vagina-cervix-uterus junction (VCUJ) of female Wistar rats. The results showed that gentle stimulation of VCUJ evoked high-amplitude electrical activity in L(3) and L(6) DRs. Hypogastric or pelvic nerve transection failed to abolish this activity. L(6)-S(1) spinal trunk transection abolished the high-amplitude electrical activity evoked in L(6) DR, while transection of the lumbosacral trunk blocked the high-amplitude electrical activity evoked in L(3) DR. These data suggest that during copulation, penile intromission likely activates the low-threshold sensory receptors of the VCUJ, thereby evoking sensory neural activity that enters the spinal cord via L(3) and L(6) dorsal roots, whose axons travel through the lumbosacral trunk and pudendal nerve.

    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.)

    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.

    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. 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 contractions (P < 0.05) and an attenuated contractile response to oxytocin. Myometrial mitochondrial copy number was reduced in older 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. © 2017 The Authors.

    Alaska Native (AN) women have exhibited some of the highest incidence rates of cancer overall, and different patterns of site-specific incidence compared to other U.S. populations. This study compares incidence rates between AN and U.S. white women (USW) for cancers of the breast, uterus, ovary and cervix, and examines effects of time period and birth cohort as determinants of incidence trends among AN women. Observational, population-based study. Cancer incidence data from the Alaska Native Tumor Registry and SEERStat, 1974-2003. Age-adjusted World Standard Population rates were calculated for a current 5-year period and over time (30 years), and compared to other populations using rate ratios with 95% confidence intervals. Log-linear regression models used to assess impact on trend of age, time period and birth cohort. Compared to U.S. white women, current cancer rates among AN women are not significantly different for cancer of the breast and cervix, and significantly lower for cancers of the ovary and uterus. Trends over time over a 30-year time period also differ for these cancer sites. There were significant increases in breast and uterine cancer, and in contrast, a marked decline in cervical cancer. There was no significant change for cancer of the ovary. Changes appear to be due largely to period, not birth cohort effects. Increases in breast cancer may be due to a combination of modifiable behaviours; increased BMI and a shift to a non-traditional diet. Increases in uterine cancer could be associated with increased BMI and diabetes. Cervical cancer rates have declined to USW levels. The marked decline is likely due to enhanced screening and control efforts within the Alaska Native Women's cancers among Alaska Natives Tribal Health System (formerly Alaska Area USPHS, Indian Health Service utilizing resources available from the Centers for Disease Control tribal and state Breast and Cervical Cancer Early Detection Programs).

    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.

    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.

    The aim of this study was to improve knowledge about histamine radioprotective potential investigating its effect on reducing ionising radiation-induced injury and genotoxic damage on the rat small intestine and uterus. Forty 10-week-old male and 40 female Sprague-Dawley rats were divided into 4 groups. Histamine and histamine-5Gy groups received a daily subcutaneous histamine injection (0.1 mg/kg) starting 24 h before irradiation. Histamine-5Gy and untreated-5Gy groups were irradiated with a dose of whole-body Cesium-137 irradiation. Three days after irradiation animals were sacrificed and tissues were removed, fixed, and stained with haematoxylin and eosin, and histological characteristics were evaluated. Proliferation, apoptosis and oxidative DNA markers were studied by immunohistochemistry, while micronucleus assay was performed to evaluate chromosomal damage. Histamine treatment reduced radiation-induced mucosal atrophy, oedema and vascular damage produced by ionising radiation, increasing the number of crypts per circumference (239±12 vs 160±10; Phistamine decreased the frequency of micronuclei formation and also significantly attenuated 8-OHdG immunoreactivity, a marker of DNA oxidative damage. Furthermore, radiation induced flattening of the endometrial surface, depletion of deep glands and reduced mitosis, effects that were completely blocked by histamine treatment. The expression of a proliferation marker in uterine luminal and glandular cells was markedly stimulated in histamine treated and irradiated rats. The obtained evidences indicate that histamine is a potential candidate as a safe radio-protective agent that might increase the therapeutic index of radiotherapy for intra-abdominal and pelvic cancers. However, its efficacy needs to be carefully investigated in prospective clinical trials. PMID:23361244

    Application of focused ultrasound stimulation (FUS) to the rat cervix during pregnancy has significant physiologic effects. One-millisecond-long pulses of 680-kHz ultrasound with a repetition frequency of 25 Hz, at ISPTA (spatial-peak, temporal-average intensity) of 1, 2 and 4W/cm(2), were applied to the rat abdomen over the cervix. FUS produced a significant change in cervical elasticity known as softening, which is part of the ripening process, comparable to the degree seen just before delivery. Timed-pregnant Sprague-Dawley rats (n = 40) were used. During gestation, the FUS system was applied to the cervix for variable times up to 1 h. Daily measurements of cervix light-induced florescence were made to estimate changes in softening. In addition, cervical stretch estimates of softening were made of isolated cervices of control and FUS-treated rats to measure distensiblity. The ultrasound power with ISPPA (spatial-peak, pulse-average intensity) of 40 W/cm(2) was considered tolerable; the U.S. Food and Drug Administration regulatory limit is 190 W/cm(2) for both the body periphery and the fetus. This is the first report of alterations induced by ultrasound in the connective tissue of the cervix and suggests the therapeutic application of ultrasound for the facilitation of labor and delivery.

    The estrogenic and antiestrogenic potential of perfluorooctanoic acid (PFOA) was assessed using an immature mouse uterotrophic assay and by histologic evaluation of the uterus, cervix and vagina following treatment. Female offspring of CD-1 dams were weaned at 18 days old and assigned to groups of equal weight, and received 0, 0.01, 0.1, or 1 mg PFOA/kg BW/d by gavage with or without 17-β estradiol (E2, 500 μg/kg/d) from PND18-20 (n=8/treatment/block). At 24 hr after the third dose (PND 21), uteri were removed and weighed. Absolute and relative uterine weights were significantly increased in the 0.01 mg/kg PFOA only group. Characteristic estrogenic changes were present in all E2-treated mice; however, they were minimally visible in the 0.01 PFOA only mice. These data suggest that at a low dose PFOA produces minimal histopathologic changes in the reproductive tract of immature female mice, and does not antagonize the cellular effects of E2.

    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.

    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.

    We studied the effect of ovariectomy, estradiol (E2), and E2 + medroxyprogesterone (MPA) on the Wistar rat uterus. We used 15 adult female rats. The study was divided into the following four stages: (a) extirpation of the upper half of the left hemi-uterus (basal state) and ovariectomy; (b) animals were maintained for 15 days without treatment, performance of a new laparotomy, and extirpation of the remaining left hemi-uterus (OVX state); (c) beginning of E2 replacement therapy (ERT) (8 microg/day) for 15 days, followed by extirpation of the upper half of the right hemi-uterus (ERT state); and (d) the administration of E2 was continued, and oral treatment with MPA was begun (20 microg/day) to last for a further 15 days. At the end of the combined hormone replacement therapy (HRT) the remaining right hemi-uterus was extirpated (HRT state). At the end of each intervention, the plasma concentrations of E2 and PRG were measured. The ovariectomy significantly reduced the malonaldehyde (MDA) levels (P < 0.0008) and catalase activity (P < 0.0006). The ERT very significantly (P < 0.0033) raised the catalase and MDA levels; these significance levels were maintained after the Bonferroni method was applied (overall error 5%). The HRT reduced the levels of MDA and catalase, but not significantly after the Bonferroni test was applied.Conclusions. Uterine oxidative stress is increased by E2, resulting in a significant increase in MDA. This may be modulated in part by the catalase activity. Although it cannot be confirmed categorically, MPA seems to intervene by decreasing the said oxidative stress.

    Carica papaya L. seeds extracted with 80% ethanol (EEPS) caused concentration-dependent tocolysis of uterine strips isolated from gravid and non-gravid rats. Prostaglandin F2alpha and oxytocin-induced contractions of the isolated rat uterus were also inhibited in a concentration-dependent fashion by EEPS. Recoveries of the uterine activity after EEPS-induced uterine quiescence were very weak. Higher concentration of EEPS caused prompt uterine quiescence, which was also significantly irreversible. Pre-incubation of the rat uterus in Ringer Locke solution containing 10 mg/ml of EEPS for 1 hour prior to suspension in tissue baths led to significant depression of the spontaneous and KCl (60 mM)-induced uterine contractions relative to the solvent control (Ppapaya seeds. Using electron impact ionization methods, the presence of BITC in EEPS was also shown in this study. Mass spectra of both EEPS and standard BITC showed a base peak of benzyl/tropylium ion at m/z 91 (indicative of an aromatic compound) and the molecular ion peak of BITC (m/z 149). Our earlier studies have demonstrated BITC-induced functional and morphological derangement of isolated uterus. We thus conclude that at high concentration, EEPS is capable of causing irreversible uterine tocolysis probably due to the damaging effect of BITC (its chief phytochemical) on the myometrium.

    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.

    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.

    We hypothesized that genistein could affect the chloride (Cl(-) ) and bicarbonate (HCO3(-) ) secretory mechanisms in uterus. Ovariectomized female rats were given estradiol or estradiol plus progesterone with 25, 50, or 100 mg/kg/day genistein. Following completion of the treatment, uterine fluid Cl(-) and HCO3(-) concentrations were determined by in vivo uterine perfusion. Uteri were subjected for molecular biological analysis (Western blot, qPCR, and immunohistochemistry) to detect levels of expression of Cystic Fibrosis transmembrane regulator (CFTR), Cl(-) /HCO3(-) exchanger (SLC26a6), Na(+) /HCO3(-) cotransporter (SLC4a4), and estrogen receptor (ER)-α and β. Coadministration of genistein resulted in decrease in Cl(-) and HCO3(-) concentrations and expression of CFTR, SLC26a6, SLC4a4, and ER-α and ER-β in the uteri of estradiol-treated rats. In estradiol plus progesterone-treated rats, a significant increase in the above parameters were observed following high-dose genistein treatment except for the SLC24a4 level. In conclusion, genistein-induced changes in the uterus could affect the reproductive processes that might result in infertility. © 2016 Wiley Periodicals, Inc.

    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.

    to study the histochemical changes related to the uterine cervix glycosaminoglycan of the albino female rat, after local administration of hyaluronidases at the end of pregnancy. ten female rats with positive pregnancy tests were randomly distributed in two numerically equal groups. The control group (Cg) was built up with rats that received a single dose of 1 mL of distilled water in the uterine cervix, under anesthesia, at the 18th pregnancy day. In the experimental group (Exg), the rats received 0.02 mL of hyaluronidase, diluted in 0.98 mL of distilled water (1 mL as a total), under the same conditions as the Cg. At the 20th pregnancy day, the rats were anesthetized once again and submitted to dissection, and the cervix prepared for histochemical study with alcian blue dye and its blockades (pH=0.5, pH=2.5, methylation and saponification). strongly positive reaction in the lamina propria (+3) has been seen in the Cg, and negative reaction in the Exg, with pH=0.5 alcian blue staining. With pH=2.5, staining has also been strongly positive (+4) in the Cg, and weakly positive (+1) in the Exg slide. After methylation, both groups have shown negative reaction, with pH=2.5 alcian blue staining. The lamina propria staining became negative after methylation in both groups, followed by saponification and enzymatic digestion on slide. there is clear predominance of sulphated glycosaminoglycans in the Cg as compared to the Exg and a small amount of identified carboxylated glycosaminoglycans in the Exg. The changes evidenced in the extracellular matrix have suggested that the hyaluronidase injected in the uterine cervix has promoted biochemical changes compatible with cervix maturation.

    Full Text Available Abstract Background Arsenic, a major pollutant of water as well as soil, is a known endocrine disruptor, and shows adverse effects on the female reproductive physiology. However, the exact molecular events leading to reproductive dysfunctions as a result of arsenic exposure are yet to be ascertained. This report evaluates the effect and mode of action of chronic oral arsenic exposure on the uterine physiology of mature female albino rats. Methods The effect of chronic oral exposure to arsenic at the dose of 4 microg/ml for 28 days was evaluated on adult female albino rats. Hematoxylin-eosin double staining method evaluated the changes in the histological architecture of the uterus. Circulating levels of gonadotropins and estradiol were assayed by enzyme-linked immunosorbent assay. Expression of the estrogen receptor and estrogen-induced genes was studied at the mRNA level by RT-PCR and at the protein level by immunohistochemistry and western blot analysis. Results Sodium arsenite treatment decreased circulating levels of estradiol in a dose and time-dependent manner, along with decrease in the levels of both LH and FSH. Histological evaluation revealed degeneration of luminal epithelial cells and endometrial glands in response to arsenic treatment, along with reduction in thickness of the longitudinal muscle layer. Concomitantly, downregulation of estrogen receptor (ER alpha, the estrogen-responsive gene - vascular endothelial growth factor (VEGF, and G1 cell cycle proteins, cyclin D1 and CDK4, was also observed. Conclusion Together, the results indicate that arsenic disrupted the circulating levels of gonadotropins and estradiol, led to degeneration of luminal epithelial, stromal and myometrial cells of the rat uterus and downregulated the downstream components of the estrogen signaling pathway. Since development and functional maintenance of the uterus is under the influence of estradiol, arsenic-induced structural degeneration may be

    Oxytocin (OT) and oxytocin receptors (OTRs) play essential roles in parturition and the effect of OT on uterine contractility is greatly influenced by the expression of OTRs in myometrium. We investigated the effect of OT on uterine strips isolated from non-pregnant, late-pregnant, term-pregnant, and labouring rats and from labouring and non-labouring women. Longitudinal uterine strips (from each gestational stage) were dissected and mounted vertically in an organ bath setup system and challenged with 5 nM OT and the effect was investigated on uterine contractility. In other experiments, phospholipase C (PLC), prostaglandin H synthase-2 (PGHS-2), and calcium-activated chloride channels (CaCCs) were blocked and the effect of OT was tested in labouring rats. OT stimulated the labouring uterus with greater force compared to other gestations in rats and also augmented the uterine force in labouring women compared to the non-labouring. However, blocking the PLC, PGHS-2, and CaCCs significantly reduced the OT-induced force increase in labouring rats. These data suggest that as labour approaches, the sensitivity of the uterine tissues to OT is greatly enhanced concomitant with the increased expression of OTR to ensure strong and adequate uterine contractions essential for the normal delivery and to prevent the postpartum haemorrhage.

    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.

    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.

    Full Text Available Objective: In the industrial world, almost everyone is unavoidably exposed to ambient electromagnetic field (EMF generated from various technical and household appliances. Thus, the aim of this study was to evaluate the diminishing effects of Citrus aurantium on uterus cell injury induced by EMF. Materials and Methods: In order to examine this, 40 female Wistar rats were selected and kept for 1 week in quarantine, and then, subdivided into two groups of 20 rats and were exposed to 40 Hz of EMF (non-ionizing radiation, 0.1 tesla for 6 weeks. Group 1 received 3 cc/rat Citrus aurantium juice, and group 2 only received 3 cc Citrus aurantium. The control group only received 3 cc water using gavage method. The materials were processed and apoptosis was observed under a light microscope using TUNEL method. Results: In the experimental rats, apoptotic cells showed significant increase in the EMF groups. However, in the exposed group that received Citrus aurantium, apoptotic cells and serum malondialdehyde (MDA were decreased and superoxide dismutase (SOD was increased (P < 0.05. Conclusion: This study showed that EMF could induce cell injury on uterus tissue, and 3 cc Citrus aurantium juice has antioxidative effects on uterus tissue by reduction of apoptosis.

    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

    Intracervix injection of hyaluronidase during pregnancy has been proposed to accelerate cervix ripening. We evaluated the morphological and morphometric changes of the uterine cervix of pregnant rats, caused by the action of this enzyme. Ten female rats were equally divided between an experimental group (G II) and a control group (G I). On the 20th day of pregnancy, under light microscopy, a greater thinning of the superficial muciferous epithelium, with lamina propria rich in blood vessels and in eosinophils was found in G II. The histometric count of G II showed a smaller number of collagen fibers (average 248 vs 552 in the control group) and a greater concentration of eosinophils (average 18.20 vs 9.20 in the control group). The Student's t-test showed a significant difference in collagen fibers (p < 0.0001) and in eosinophils (p < 0.0007). The action of this enzyme caused a predominance of flaccid connective tissue, a lower concentration of collagen fibers and an increased concentration of eosinophils, confirming its utilization in cervix ripening.

    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. MÉTODOS: Uma rata Wistar prenhe foi submetida à laparotomia no 18º dia de gestação e o cérvix uterino foi suturado com 3-0 nylon, impedindo o parto normal que normalmente ocorre no 21º dia de gestação. A sutura foi liberada 48 horas após o período gestacional normal. A rata gestante deu à luz 11 animais. Seis

    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, 2mg/kg) by sc injection every 48h 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 differentiation. PR and Hoxa10 were deregulated both immediately and two weeks after the exposure. ERα was induced in the stromal compartment on PND8, and was downregulated in the luminal epithelial cells of gyphosate-exposed animals on PND21. GBH treatment also increased

    Full Text Available Resveratrol is a phytoalexin produced in a number of plant species including grapes. The benefit of resveratrol to health is widely reported. Resveratrol has been found to promote relaxation of non-pregnant and pregnant uterus, but its mechanism of action is unclear. The aims of our study were to investigate the involvement of inwardly rectifying potassium channels (Kir in inhibitory effects of resveratrol on three models of contractions of non-pregnant rat uterus: the spontaneous rhythmic contractions (SRC, oxytocin-elicited phasic contractions and tonic oxytocin-elicited contractions.Uterine strips were obtained from virgin female Wistar rats in oestrus. Strips were mounted into organ bath for recording isometric tension in Krebs-Ringer solution. Experiments followed a multiple curve design. In order to test the involvement of Kirchannels in a mechanism of action of resveratrol(1-100 μM,BaCl2 (1 mM,a antagonist of inwardly rectifying pota­ssium channels was used. Resveratrol induced a concentration-dependent relaxation of all models of contractions. BaCl2 antagonized the response to resveratrolon SRC and oxytocin-elicited phasic contractions. Relaxation achieved by resveratrolon tonic oxytocin-elicited concentrations was insensitive to BaCl2.The antagonism of resveratrol effects by inwardly rectifying potassium channels antagonist suggests that Kir channels are involved in resveratrol action on phasic contractions of rat uterus. Inhibitory effect of resveratrol on tonic contractions did not include Kir channels. [Projekat Ministartsva nauke Republike Srbije, br. TR31020

    To assess the local effect of hyaluronidase injection on the expression of glycosaminoglycans (GAGs) and proteoglycans (PGs) in the extracellular matrix of the uterine cervix from pregnant albino rats. Ten pregnant rats were divided into two groups on day 18 of pregnancy. The experimental group (Gexp) of rats received an intracervical infusion of 0.02 mL of hyaluronidase diluted to 1 mL with distilled water, whereas the control group (Gc) received 1 mL of distilled water. On day 20 of pregnancy, the pregnant rats were sacrificed and the uterine cervixes from all rats were then dissected. The qualitative expression of hyaluronic acid (HA) was assessed by immunohistochemistry and quantified by sandwich ELISA. To compare the quantitative GAG values between groups, a Student's t-test for independent samples was performed. PGs were also assessed by immunohistochemical analysis. The electrophoretic profile of newly synthesized radioactively labeled GAGs degraded by specific enzymes showed that there were two predominant GAGs in both Gc and Gexp, i.e. heparan sulfate (HS) and a mixture of hondroitin sulfate (CS) and dermatan sulfate (DS). The concentrations of GAGs showed a significant reduction of CS/DS (p < 0.004) and HS (p < 0.005) relative to Gc. HA staining was less intense in the lamina propria and area surrounding the blood vessels in Gexp compared to Gc. The HA contents were also significantly reduced (p < 0.012). Intracervical hyaluronidase infusion promoted a significant reduction in the concentration of sulfated GAGs as assessed by both qualitative (histochemical) and quantitative (fluorometric) measurements of HA.

    [corrected] Mifepristone is a synthetic antiprogestin which terminates early pregnancy. Since it interferes with the progesterone maintained decidua, we compared the effect of mifepristone on oestrogen and progesterone receptors, and on the biotransformation of these hormones in normal and deciduous uterus. Ovariectomized rats were treated with an oestrogen-progesterone hormone regimen and deciduoma was induced by trauma in one horn of the rat uterus while the other served as a control under an identical hormonal milieu. Hormone receptor and biotransformation studies were done using radiolabelled oestradiol and progesterone with high specific activity. The artificially formed decidual tissue was comparable with that of early pregnancy. Mifepristone replenished oestrogen and progesterone receptors which were suppressed by progesterone in both the normal and decidualized uterine horns. Inhibition of oestrogen receptors by progesterone correlated with decreased oestradiol levels at the site of action. Metabolism of progesterone to less potent compounds was promoted by mifepristone. The enzymatic activities of 17beta-hydroxysteroid dehydrogenase (which metabolizes oestradiol), and 20alpha-hydroxysteroid dehydrogenase and 5alpha-reductase (which metabolize progesterone) were altered by mifepristone. The effect of mifepristone in varying the hormone receptor population and the availability of different levels of active metabolites of ovarian hormones have an Important role in the antiprogestin action of mifepristone.

    Calcitonin gene-related peptide (CGRP) is a potent smooth muscle relaxant in a variety of tissues. We recently demonstrated that CGRP relaxes uterine tissue during pregnancy but not during labor. In the present study we examined whether uterine (125)I-CGRP binding and immunoreactive CGRP receptors are regulated by pregnancy and labor and by sex steroid hormones. We found that (125)I-CGRP binding to membrane preparations from uteri was elevated during pregnancy and decreased during labor and postpartum. Changes in immunoreactive CGRP receptors were similar to the changes in (125)I-CGRP binding in these tissues, suggesting pregnancy-dependent regulation of CGRP receptor protein. CGRP receptors were elevated by Day 7 of gestation, and a precipitous decrease in these receptors occurred on Day 22 of gestation prior to the onset of labor. Both (125)I-CGRP-binding and immunofluorescence studies indicated that CGRP receptors were localized to myometrial cells. Hormonal control of uterine CGRP receptors was assessed by the use of antiprogesterone RU-486, progesterone, and estradiol-17beta. RU-486 induced a decrease in uterine CGRP receptors during pregnancy (Day 19). On the other hand, progesterone prevented the fall in uterine CGRP receptors at term (Day 22). In addition, progesterone also increased uterine CGRP receptors in nonpregnant, ovariectomized rats, while estradiol had no effects. These hormone-induced changes in uterine CGRP receptors were demonstrated by (125)I-CGRP-binding, Western immunoblotting, and immunolocalization methods. These results indicate that CGRP receptors and CGRP binding in the rat uterus are increased with pregnancy and decreased at term. These receptors are localized to the myometrial cells, and progesterone is required for maintaining CGRP receptors in the rat uterus. Thus, the inhibitory effects of CGRP on uterine contractility are mediated through the changes in CGRP receptors and may play a role in uterine quiescence during pregnancy.

    The aim of this study was to evaluate the relaxant and anti-inflammatory effects of two thalidomide analogs as phosphodiesterase-4 (PDE-4) inhibitors in pregnant rat uterus. Uteri from Wistar female rats were isolated at 19 day of pregnancy. Uterine samples were used in functional studies to evaluate the inhibitory effects of the thalidomide analogs, methyl 3-(4-nitrophthalimido)-3-(3,4-dimethoxyphenyl)-propanoate (4NO2PDPMe) and methyl 3-(4-aminophthalimido)-3-(3,4-dimethoxyphenyl)-propanoate (4APDPMe), on prostaglandin-F2α (PGF2α)-induced phasic, K+-induced tonic, and Ca2+-induced contractions. Accumulation of cAMP was quantified in uterine homogenates by ELISA. Anti-inflammatory effect was assessed by using ELISA for determination of the pro-inflammatory cytokines tumor necrosis factor-α (TNFα) and interleukin (IL)-1β, and anti-inflammatory IL-10, from uterine explants stimulated with lipopolysaccharide (LPS). Nifedipine, forskolin and rolipram were used as positive controls where required. Both thalidomide analogs induced a significant inhibition of the uterine contractions induced by the pharmaco- and electro-mechanic stimuli. Nifedipine and forskolin were more potent than the analogs to inhibit the uterine contractility, but these were more potent than rolipram, and 4APDPMe was equieffective to nifedipine. Thalidomide analogs increased uterine cAMP-levels in a concentration-dependent manner. The LPS-induced TNFα and IL-1β uterine secretion was diminished in a concentration-dependent fashion by both analogs, whereas IL-10 secretion was increased significantly. The thalidomide analogs induced utero-relaxant and anti-inflammatory effects, which were associated with the increased cAMP levels as PDE-4 inhibitors in the pregnant rat uterus. Such properties place these thalidomide analogs as potentially safe and effective tocolytic agents in a field that urgently needs improved pharmacological treatments, as in cases of preterm labor.

    Eleven patients with an obstructed, fluid-filled uterus, due to carcinoma of the uterus or to its treatment by radiation therapy, were examined with computed tomography (CT) and/or ultrasound. It is important to recognize this abnormality to differentiate it from other causes of pelvic mass and to ensure prompt treatment of pyometra, should it develop. Both CT and ultrasound reliably identified this condition and differentiated it from other pelvic masses.

    High Abcg2 (ATP-Binding Cassette Transporter Subfamily G, Member-2) levels have been found in reproductive tissues, such as the placenta and uterus. The substrate specificity of Abcg2 is very wide, including uterus-relaxant agents (e.g. nifedipine and prazosine). Through the use of a potent inhibitor (KO134), intracellular accumulation of the substrate can be increased. Nifedipine, commonly used in acute tocolytic therapy, exerts a greater tocolytic effect and has fewer side-effects than β2-adrenergic receptor agonists. The aims of the present study were to investigate the expression of Abcg2 in the rat uterus during gestation and the uterus-relaxant effect of nifedipine in the presence of the Abcg2 inhibitor KO134. Real-time Polymerase Chain Reaction (PCR) and western blot analyses were performed to detect the levels of Abcg2 during gestation in the rat. The uterus-relaxant effect of nifedipine in vivo was investigated by the intra-uterine pressure measuring method, described by Csapo. Low levels of Abcg2 were found in non-pregnant animals and early-pregnancy (days 6, 8 and 10), but on day 15 of gestation, a sharp increase in Abcg2 levels was observed, which reached its maximum on day 18 and later decreased until the end of gestation. The post-partum levels were similar to those in non-pregnant rats. The in vivo contractility studies revealed that nifedipine had a strong uterus-relaxant effect on spontaneous contractions, and that this effect was significantly and dose-dependently increased by the Abcg2 blocker KO134. The administration of efflux pump inhibitors in combination with tocolytic agents may be of novel therapeutic relevance in the management of pre-term labour.

    The expression of oestrogen receptors (ERalpha and ERbeta) in the prostate and uterus tissues of Wistar rats supplied for 8 weeks with a diet rich in sesame (Sesamum indicum) pericarp (30 %) was monitored. Eight male rats, aged 6 weeks, were divided into a control group fed on a normal diet, and an experimental one, provided with the normal diet enriched with 30 % sesame pericarp. A similar experiment was performed with female rats. At the end of the experiment, the prostate and uterus tissues were surgically removed and kept at - 80 degrees C for up to 2 months. Western blotting and quantitative real-time PCR (qRT-PCR) methods were used in order to investigate the levels of receptor proteins and mRNA. Significant increase in the expression of ERbeta in prostate and uterus was evident in both methods, while the magnitude of the observed alteration depended on the applied method. No statistically significant change was observed in the expression of ERalpha in uterus. In prostate, although the increase was more evident when investigated by means of qRT-PCR, the difference in expression of ERalpha was not statistically significant. In both tissues, a shift of the ratio of ERalpha:ERbeta in favour of ERbeta was evident, indicating, according to existing literature, a beneficial effect of the diet provided upon the health status of the organisms. It is suggested that this effect is attributed to the lignans present in the pericarp which exert phyto-oestrogenic activity.

    Full Text Available The aim of present study was to determine the distributions of proliferating cell nuclear agent (PCNA and Cas-pase-3 (Cas-3 and their possible roles in implantation and decidualization during early pregnancy at immunohistochemical level. The tissue samples from pregnant animals between gestational days 1-5 were incubated by PCNA and Cas-3 antibodies and the obtained results were evaluated quantitatively. It was observed that PCNA immunoreactivity in uterine luminal epithelium and glandular epithelium reduced as from day 2 of gestation and disappeared as from day 4 of gestation. PCNA staining intensity in stromal cells and myometrium increased gradually with progressing gestation. While Cas-3 immunoreactivity was strongly detected in luminal and glandular epithelium throughout the whole gestational period, its reactivity markedly increased as from day 3 of gestation. In conclusion, it may suggest that the blastocyst implantation induces the uterine luminal epithelial cell death and stromal cell proliferation around the embryo in the uterus.

    The aim of the present study was to investigate variation in the expression pattern of ornithine decarboxylase (ODC1), spermine (SPM), spermidine (SPD) and antizyme inhibitor (AZIN1) in hypothalamus, ovary and uterus during the estrous cycle of rats. Further, to understand any correlation between polyamines and GnRH I expression in hypothalamus; effect of putrescine treatment on GnRH I expression in hypothalamus and progesterone and estradiol levels in serum were investigated. The study also aims in quantifying all the immunohistochemistry images obtained based on pixel counting algorithm to yield the relative pixel count. This algorithm uses a red green blue (RGB) colour thresholding approach to quantify the intensity of the chromogen present. The result of the present study demonstrates almost similar expression pattern of polyamine and polyamine related factors, ODC1, SPD, SPM and AZIN1, with that of hypothalamic GnRH I, all of which mainly localized in the medial preoptic area (MPA) of the hypothalamus, during the proestrus, estrus and diestrus. This suggest that hypothalamic GnRH I expression is under regulation of polyamines. The study showed significant increase in hypothalamic GnRH I expression for both the doses of putrescine treatment to adult female rats. Further, it was shown that in ovary expression pattern of ODC1, SPM, SPD and AZIN1 were similar with that of steroidogenic factor, StAR during the estrous cycle, and putrescine supplementation increased significantly estradiol and progesterone levels in serum, all suggesting ovarian polyamines are involved in regulation of ovarian steroidogenesis. Localization of these factors in the theca and granulosa cells suggest involvement of polyamines in the process of folliculogenesis and luteinization; and ODC1, SPD, SPM and AZIN1 in oocyte further suggests polyamine role in maintenance of oocyte physiology. Finally, in uterus SPM and AZIN1 were localized throughout the estrous cycle, being comparatively more

    Leonurus artemisia (Lour.) S.Y.Hu (Lamiaceae) (YiMuCao in Chinese) is a traditional Chinese medicine. Leonurus artemisia has been shown to have many pharmacological effects such as increasing uterine contraction amplitude, and tension, but the active components are still unknown. The objective of this study is to determine active components of L. Artemisia that are responsible for the biological activity using HPLC and cell membrane-based system. The whole L. artemisia ethanol extract and its eight fractions were screened using Sprague-Dawley rat uterus cell membrane chromatography (CMC) combined with the HPLC/MS system. Oxytocin was used to investigate the activity of CMC column. The effect of active components screened from L. artemisia was studied by tension measurement of isolated rat uterine strips in vitro at a dose of 10(-7)-10(-4 )mol/L with oxytocin as a control. The acetone extract showed obvious activity when compared with the eight extracts of L. artemisia. From the acetone extract, in the negative ionization mode, the active compound was identified as genkwanin, with a molecular weight of 283. In vitro pharmacological experiments proved that genkwanin promoted uterine contractions at a dose from 10(-7) to 10(-4 )mol/L. The EC50 value was 4.86 ± 4.21 μmol/L for genkwanin and 4.30 ± 3.65 μmol/L for oxytocin on the contractile amplitude of uterine strips isolated from rats. Genkwanin was identified as the active compound in L. artemisia by this method. In vitro pharmacological experiments proved that genkwanin promoted uterine contractions. Genkwanin may be used to uterine inertia and may have an effect on postpartum hemorrhage.

    The objective is to compare the prognosis value of the pre-therapy pelvis PET--T.D.M. with {sup 18}F-F.D.G. and MRI in the uterine cervix carcinoma. The conclusions: in the uterine cervix carcinomas, the existence of a pelvis ganglion injury on the pre-therapy PET-T.D.M. with {sup 18}F-F.D.G. is a prognosis factor independent of recurrence and death at one year. The MRI does not bring any additional information relative to the prognosis of the disease. (N.C.)

    The leaves of Ficus exasperata Vahl Enum. Pl. vahl (Moraceae) are used by traditional healers in Southern Nigeria and some parts of Africa to avoid preterm births. However, previous reports showed that the plant also exhibited uterine contractions at specific concentrations. This study is therefore aimed at investigating the purported uterine inhibitory aspect of the plant on the isolated rat uterus. The aqueous extract (AET) was tested on rhythmic spontaneous uterine contractions. Concentration-response relationships were obtained for oxytocin (OT), acetylcholine (ACh) and ergometrine (EGM), in the presence or absence of fixed concentrations of AET. Salbutamol (SBL) and verapamil (VER) were used as positive controls. AET, at 1.0 x 10(-2) mg/mL, significantly increased (p contractions but had no significant effect on ACh, EGM and spontaneous uterine contractions. However, SBL and VER significantly increased (p uterine contractions. The aqueous leaf extract of F. exasperata inhibits oxytocin-induced uterine contractions at the concentration shown in this study. This observation may explain its folkloric use in counteracting preterm contractions and alleviating dysmenorrhoea.

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.

    Uteri of pregnant rats on Days 6, 7 and 8 of pregnancy were studied to determine the histochemical distribution of collagen types III and V and the incorporation of [3H]glycine into fibrillar collagens during the period of embryonic implantation. Types III and V had a similar distribution in the non-decidual stromal region and muscle layers in implantation sites. They were found to have very low levels in the primary decidual tissue on Day 6 and were not detected in developing decidual tissues on Days 7 or 8. Following injection of labelled glycine, collagen was extracted and the specific activity of the collagens determined by fluorography and 3H incorporated into the collagen bands in the gels. It was found that incorporation of label into both types I and III was similar (33.4+/-12.0 and 31.8+/-18.1 cpm microg-1 collagen respectively) but 3.5 times that of type V (7.7+/-5.3 cpm microg-1). These studies suggest that although fibrillar collagens are metabolized or redistributed in the growing decidual tissue, they are incorporated rapidly into the extracellular matrix during remodelling of the outer stroma and muscle tissues.

  11. Masculinization and defeminization of female rats by males located caudally in the uterus.

    It is assumed that female rats are masculinized by the presence of males in the same uterine horn. Two hypotheses regarding the mechanism have been proposed: 1) interamniotic diffusion of androgens (contiguity hypothesis) and 2) transport of androgens via the bloodflow (caudal male hypothesis). This study was designed to test these hypotheses while taking into account two previously uncontrolled factors: hemihysterectomy of the mother during pregnancy and birth by caesarean section. Pregnant females were hemihysterectomized during pregnancy or left intact; pups were born naturally or through caesarean section. Position in utero was determined. In adulthood all females were ovariectomized and tested for mounting behavior before and during testosterone treatment and lordosis behavior during estradiol treatment. It was found that females with males located caudally in the same uterine horn were more masculinized and defeminized than females without such males. Adjacent males had no influence on the behavioral sexual differentiation of females. These results confirm the "caudal male hypothesis" rather than the "contiguity hypothesis." Hemihysterectomy during pregnancy prevented the "caudal male effect." Birth through caesarean section did not interfere with the caudal male effect.

    Biopsies from different segments of the pregnant human uterus were superfused in organ chambers and contractile activity was registered. Leukotriene C4(LTC4) caused inhibition of spontaneous but not noradrenaline induced contractile activity in strips from the cervix. This effect occurred both in early pregnancy and at term. However, the lower and the upper uterine segment of the term pregnant uterus did not respond to LTC4. The results represent a documentation of the segmental differentiation in the uterine response to eicosanoids.

    Our aims were to examine the effects of a simultaneous stimulation of β(2) -adrenergic receptors and inhibition of uterine phosphodiesterases (PDE), in the pregnant rat uterus in vivo and on human uterine tissue in vitro. We also set out to measure cAMP levels and detect the expressions of the isoenzymes PDE4B and PDE4D in human uterine tissue samples. Preterm birth was induced in Sprague-Dawley rats with bacterial lipopolysaccharide. The uterine effects of terbutaline alone or in combination with rolipram were tested in vivo. Human myometrial strips from cesarean sections at full-term pregnancy and at preterm labor were stimulated with oxytocin, and the inhibitory effects of theophylline, rolipram and terbutaline were studied. The myometrial accumulation of cAMP in the presence of rolipram and terbutaline was determined by enzyme immunoassay. The expressions of PDE4B and PDE4D proteins were detected by Western blotting. The selective PDE4 inhibitor rolipram was more effective than the non-selective PDE inhibitor theophylline in inhibiting the oxytocin-induced contractions in the human uterus. The uterus-relaxing effects of low doses of terbutaline were markedly potentiated by rolipram, both in rats and in human tissues. The changes in uterine cAMP levels correlated with these results. At preterm labor, PDE4B was the predominant form of PDE4 expressed; at full term, PDE4D was expressed more strongly. A combination of selective PDE4 inhibitors and β(2) -agonists should be considered for the treatment of preterm contractions. © 2012 The Authors.

    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

    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 (H2O2) 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.

    Abstract Sex hormone replacement therapy provides several advantages in the quality of life for climacteric women. However, estrogen-induced cell proliferation in the uterus and mammary gland increases the risk of cancer development in these organs. The lower incidence of mammary cancer in Asian women as compared with Western women has been attributed to high intake of soy isoflavones, including genistein. We have previously shown that genistein induces an estradiol-like hypertrophy of uterine cells, but does not induce cell proliferation, uterine eosinophilia, or endometrial edema. It also inhibits estradiol-induced mitosis in uterine cells and hormone-induced uterine eosinophilia and endometrial edema. Nevertheless, genistein stimulates growth of human breast cancer cells in culture; therefore, it is not an ideal estrogen for use in hormone replacement therapy (HRD). The present study investigated the effect of another soy isoflavone, daidzein (subcutaneous, 0.066 mg/kg body weight), in the same animal model, and its effect on responses induced by subsequent treatment (1 h later) with estradiol-17β (E2; subcutaneous, 0.33 mg/kg body weight). In addition, we investigated the effects of daidzein (1 μg/mL) or E2 on the growth of human breast cancer cells in culture. Results indicate that daidzein stimulates growth of breast cancer cells and potentiates estrogen-induced cell proliferation in the uterus. We suggest caution for the use of daidzein or formulas containing this compound in HRD. Future research strategies should be addressed in the search for new phytoestrogens that selectively inhibit cell proliferation in the uterus and breast. PMID:23216111

    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 pyometra (77%, 30/39 dogs) compared to open cervix pyometra (51%, 36/71 dogs) (p = 0.007). Presence of prolonged postoperative hospitalization did not differ significantly between the two groups. In dogs with closed cervix, sepsis was more common, the general physical condition more often moderately to severely depressed and leukocytosis, neutrophilia and monocytosis more frequently found. The results showed that closed cervix was associated with a more severe illness than open cervix at admission but not with poorer outcome as measured by postoperative hospitalization. These findings may be clinically valuable for optimizing monitoring and treatments in dogs with the disease.

    We studied the potential of both stereoisomers of 17alpha-[123I]iodovinyloestradiol (E- and Z-[123I]IVE) and of 11beta-methoxy-17alpha-[123I]iodovinyloestradiol (E- and Z-[123I]MIVE) as suitable radioligands for the imaging of oestrogen receptor(ER)-positive human breast tumours. The 17alpha-[123I]iodovinyloestradiols were prepared stereospecifically by oxidative radio-iododestannylation of the corresponding 17alpha-tri-n-butylstannylvinyloestradiol precursors. Competitive binding studies were performed in order to determine the relative binding affinity (RBA) of the unlabelled 17alpha-iodovinyloestradiols for the ER in both human MCF-7 breast tumour cells and rat uterine tissue, compared with that of diethylstilboestrol (DES). Target tissue uptake, retention and uptake selectivity of their 123I-labelled analogues were studied in immature female rats. All four 17alpha-iodovinyloestradiols showed high affinity for the ER in human MCF-7 cells, as well as rat uterus. Their RBA for the ER showed the following order of decreasing potency: RBA of DES >Z-IVE >Z-MIVE >E-MIVE > or =E-IVE. Neither of these 17alpha-iodovinyloestradiols showed any significant binding to the sex hormone binding globulin in human plasma. The biodistribution studies showed ER-mediated uptake in the uterus, ovaries and pituitary, that of E- and Z-[123I]MIVE being higher than that of E- and Z-[123I]IVE. High target-to-non-target tissue uptake ratios, especially at longer periods after injection (up to 24h), were exhibited by both isomers of [123I]MIVE. The uterus-to-blood uptake ratio was higher for E-[123I]MIVE. However, the uterus-to-fat uptake ratio appeared to be higher for the Z-isomer of [123I]MIVE, especially at 24h after injection. Metabolic properties and temperature effects, which play a more important role in vivo, probably cause the discrepancies seen between in vitro and in vivo binding results. On the basis of their in vitro binding properties and in vivo distribution characteristics

    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. Quercetin-induced changes in the uterine fluid secretion rate and electrolytes

    Full Text Available Background. Didelphys uterus is a noncommon finding in women. Till now, few cases with benign mesenchymal tumors in patients with didelphys uterus are described. We present a case of a patient with carcinosarcoma arising in a didelphys uterus. Case. A 73-year-old patient presented with profuse watery postmenopausal bleeding. On examination under anesthesia, left and right cervixes were identified. Tumor extended from the left cervix into the lower third of the vagina and was adherent to the right vaginal sidewall. There was no evidence of parametrial extension. Tissue was sent for biopsy which revealed high-grade uterine carcinosarcoma. Two uterine fundi and two vaginas in keeping with uterine didelphys were identified on imaging. The patient underwent vaginal excision of the protruding tumor measuring  cm with harmonic scalpel followed by total abdominal hysterectomy and bilateral salpingooophorectomy. Although a number of pelvic and paraaortic lymph nodes were also identified on imaging, she was not planned for lymphadenectomy after MDT (multidisciplinary team discussion because of her comorbidities. The final histology confirmed the diagnosis. Conclusion. According to our knowledge, this is the second case of carcinosarcoma arising in didelphys uterus in the world literature.

    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.

    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.

    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 C60(OH)24 nanoparticle (FNP) in DMSO. FNP is a water-soluble derivative of fullerene C60. 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.

    Morphological evidence for a denervation of the human myometrium during pregnancy has previously been demonstrated. In the present study the innervation of the human cervix has been investigated in nonpregnant, early pregnant and term pregnant women. An indirect immunofluorescence method, using an antiserum to the Schwann cell specific S-100 protein, was applied to document the distribution of nerve fibers in cervical tissue biopsies. In nonpregnant, as well as in pregnant women, the cervix was by far more densely innervated than the rest of the uterus. No obvious difference in nerve density was observed between nonpregnant, early pregnant and term pregnant women, and still during labor the innervation appeared morphologically preserved. It is suggested that the segmental difference in innervation of the human uterus (corpus versus cervix) may have specific importance for myometrial and cervical contractility during pregnancy and parturition.

    The uterus is one of the target organs of sexual steroids synthesized in the ovary. Estrogen is known to stimulate cell proliferation in the endometrium while progesterone has an anti-estrogenic secretory effect on this tissue. Renewed interest in the action of new anti-estrogenic agents on the uterus has arisen over the last decade, but not simply in order to achieve new therapeutic strategies for the prevention or cure of uterine tumors. New compounds were developed for their action on other tissues such as the breast, but it rapidly became clear that they were a source of uterine disease. A clear example is tamoxifen which has a powerful anti-estrogenic effect on breast tissue. It was hoped however that this compound, which behaves either like an antagonist or an agonist, depending on the target tissue, could have an anti-estrogenic effect on the uterus and on the contrary an agonistic estrogenic protective effect on bony and vascular tissue. This approach progressively led to the development of SERMs (Selective Estrogen Receptor Modulators), non-steroidal compounds modulating the action of estrogens. The first member of this new pharmaceutical class was raloxifen, marketed in France under the brand name Evista, which has an estrogenic effect on vertebral bone, warranting its authorization for use in patients with vertebral osteoporosis with or without fracture. Raloxifen thus has a beneficial estrogenic effect, at least on trabecular bone, and an anti-estrogenic effect on the uterus and breast. The goal today is to continue the development of new compounds in the SERM family with well targeted, and well understood, agonistic and/or antagonistic actions on different body tissues.

    Adenoid cystic carcinoma (ACC) of the uterine cervix is a rare primary neoplasm of the uterus that occurs in post-menopausal women; its radiological findings have not been described previously. We present the MR findings of a case of ACC. The mass exhibited homogeneous low-signal intensity on T1-weighted images. On T2-weighted images, the mass showed high-signal intensity with a lobulated contour and multiple septum-like internal architectures. It also contained spots of very high-signal intensity, which would represent the mucin in the glandular lumen. The multiple septum-like internal architectures probably represented interglandular fibrous stroma. These MRI findings may be helpful for future diagnoses of ACC of the uterine cervix. (orig.)

    Effects of endothelin on nonvascular smooth muscle have been examined using rat uterine horns and two modes of endothelin action have been revealed. Endothelin (0.3 nM) caused rhythmic contractions of isolated uterus in the presence of extracellular calcium. The rhythmic contractions were completely inhibited by calcium channel antagonists. These characteristics of endothelin-induced contractions were very similar to those induced by oxytocin. Binding assays using /sup 125/I-endothelin showed that endothelin and the calcium channel blockers did not compete for the binding sites. However, endothelin was unique in that it caused, in addition to rhythmic contractions, a slowly developing monophasic contraction that was insensitive to calcium channel blockers. This developing contraction became dominant at higher concentrations of endothelin and was also calcium dependent.

Action efficiency of sodium nitrite in a similar concentration was significantly lower than that of sodium nitroprusside. It is shown that it was sodium nitroprusside which caused a slight swelling of the mitochondria. A possible protecting role of nitric oxi­de as to mitochondria was discussed.

    Previous results in this laboratory indicate that protamine sulfate (PS) evokes dose-dependent relaxation of both spontaneous and calcium ion-induced uterus activity mediated predominantly by potassium channels and, to a small extent, via β-adrenergic receptors or nitric oxide (NO)-dependent pathways. Indometacin is a nonselective inhibitor of cyclooxygenase (COX 1 and COX 2) that has the ability to delay premature labor by reducing uterine contractions through the inhibition of prostanglandin synthesis in the uterus. This study investigates the effects of indometacin (0.1 and 1 μg/ml) pretreatment on the PS-induced relaxation of isolated uterine smooth muscle. Indometacin pretreatment per se did not change the activity of the uteri. However, indometacin significantly increased PS-induced relaxation of spontaneous uterine contractions. Indometacin pretreatment significantly decreased the magnitude and slope of PS-induced relaxation of calcium ion-induced uterine contractions. Indometacin pretreatment increased CuZnSOD activity and slightly increased GR activity during spontaneous uterine contractions when compared to PS alone. In calcium ion-induced contractions, indometacin pretreatment increased CuZnSOD, GSH-Px and GR activities. These results suggest that, in addition to its COX inhibitory effects, indometacin influences the effects of PS. Therefore, it is possible that indometacin regulates diverse cell functions via its association with lipid membranes by altering micro-environments within the membranes. The above-mentioned processes appear to be partly mediated by redox processes involving ROS, lipid peroxides and antioxidant enzymes. The extent of the PS-mediated effect as different in spontaneous versus calcium ion-induced active uteri.

    Full Text Available Lymphoma of the uterine cervix is very rare. We report a case of diffuse large B cell lymphoma (DLBCL involving the uterine cervix treated at a newly commissioned semiurban cancer centre in north India in 2015. Data for this study was obtained from the hospital electronic medical records and the patient’s case file. We also reviewed published case reports of uterine and cervical lymphoma involving forty-one patients. We treated a case of stage IV DLBCL cervix with six cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone and intrathecal methotrexate followed by consolidation with radiotherapy. The patient showed complete response to chemotherapy. We conclude that, in advanced stage lymphoma involving uterus and cervix, combination of chemotherapy and radiotherapy is effective in short term.

    The retrospective study included the total laparoscopic hysterectomy without uterus manipulator at big uterus >280 g (Group A), proceeding the same technique as known to show feasibility and safety of its technique, compared with a randomized patient group of a uterus weight below 280 g (Group B). Statistical measurement was proceeded in typical clinical parameters. No statistical differences in age, body mass index, further abdominal surgery, blood loss, and hospital stay were observed. Operating time was significantly different favouring the uterus below 280 g (111.74 min Group A/90.68 min Group B). No increase in intra- or postoperative complications in both groups was observed. Total hysterectomy at big uterus (>280 g) is safe and feasible. Statistical analysis shows a significant shorter operating time only in one parameter (Group B). The technique of hysterectomy without uterus manipulator offers a surgical advancement also at vaginal stenosis, early staged cervix, or endometrial cancer and exhibits an opportunity for laparoscopic advancement in these cases too.

    Dynamic magnetic resonance (MR) imaging was performed to evaluate eight normal uteri and 29 cervical carcinomas. After rapid injection of gadopentetate dimeglumine, dynamic images were obtained every 30 seconds with the spin-echo (SE) technique in the sagittal plane or the fast low-angle shot (FLASH) technique in the axial plane. In the normal uterus, initial slight enhancement of the junction between endometrium and myometrium was followed by enhancement of the uterine myometrium. Cervical carcinoma was readily distinguished from the cervical stroma and myometrium in the early dynamic phase (30-60 seconds). Tumor-cervix contrast in the early dynamic phase was significantly more marked with the dynamic SE technique than with T2-weighted or contrast material-enhanced T1-weighted imaging (P less than .01). For the evaluation of parametrial invasion, the dynamic FLASH study showed better contrast than did T2-weighted images. Among 18 patients who underwent surgery, accurate assessment of the degree of stromal invasion and tumor size was possible with dynamic MR images in 14 patients (78%), T2-weighted images in 11 (61%), and postcontrast T1-weighted images in seven (39%).

    Full Text Available PURPOSE: Verify the effect of oophorectomy on the evolution of the Walker 256 tumor inoculated into the vagina and cervix of female rats. METHODS: Ten Wistar, female rats were used, distributed into two groups with 05 animals each: Tumor group (TG: Rats inoculated with Walker 256 tumor; Oophorectomy group (OG: oophorectomized rats inoculated with Walker 256 tumor. The day before the tumor vaginal inoculation, acetic acid was inoculated into the vaginas of both groups of rats; the following day, the vaginal walls were scarified with an endocervix brush, and then Walker 256 tumor was inoculated. After 12 days, the tumor was removed together with the vagina and uterine horns for macro and microscopic analyses. The data were submitted to statistical analyses. RESULTS: There was no statistical difference between the two groups; however it was observed that the behavior of tumor growth on the OG group presented greater invasion, compromising the uterine horns. CONCLUSION: The results of the study on the GO group presented a macroscopic behavior different from the TG group, however, both of them presented similar development in terms of tumor mass.OBJETIVO: Verificar o efeito da ooforectomia à inoculação do tumor de Walker 256 em vagina e colo de útero de ratas.

    Full Text Available PURPOSE: To establish an inoculation model of Walker 256 carcinoma on cervix uteri and vagina of rats. METHODS: Fifteen female rats were used, and assigned to three groups each one with five rats: group A - rats with 4x10(6 cells of Walker 256 carcinoma without acid acetic inoculation; group B - rats with 2x10(6 cells of Walker 256 carcinoma with acid acetic inoculation and group C: rats with 4x10(6 cells of Walker 256 carcinoma with acid acetic inoculation. The day before tumor cells inoculation the rats from groups B and C were anaesthetized with diethylether and 0,3 ml of acetic acid was inoculated into their vaginas. Tumor cell inoculation into the vagina and cervix was done under general anesthesia with diethylether. Then a endocervical brush was used to scrape the vaginal wall and after that 0,3 ml of the liquid containing tumor cells was inoculated on the vagina and cervix. For the tumor analysis, animals were euthanized at day 12 following tumor cell implantation by an excessive inhalation of diethylether. Tumor was resected entirely and weighed and the tumors were then sectioned and counter stained with hematoxylin and eosin for histopathologic evaluation. It was also calculated the percentage of tumor equivalent to the body weight by the formula: P= tumor weight / body weight x 100. Data were analyzed by one-way analysis of variance - ANOVA.

    Uterus transplantation is an experimental treatment method with an ambition to become accepted treatment modality for women with absolute uterine factor infertility. The only legal alternative for these women to get parenthood is adoption which is accepted by most world societies and countries. Surrogate pregnancy is connected with many medical, ethical, legal, religious and social controversies in the great part of the world.Donors (in living donation), recipients, partners and also unborn children must be incorporated into the analysis of ethical risks and benefits of uterus transplantation. The main ethical risks for the recipient are surgery, immunosuppression, pregnancy and delivery. All the potential recipients have to be advised about further ethical issues like organ rejection, infection, side effects of the drugs, unsatisfactory fertilization and different complications during pregnancy.Uterus procurement in donor takes longer time than in standard hysterectomy due to preparation of uterine arteries and veins. Vessels with 2 mm diameter and their anatomical collision with ureter are connected with higher peroperative risk of uneventful surgical complications. Ethical issues might be connected with the uterus procurement in dead brain donors identically.The deliveries after uterus transplantation are fruitful but the risk of preterm delivery and immaturity of the newborns cannot be underestimated as well.

    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.

    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.

    Although uterus and cervix infiltration is a frequent finding in the later stages of lymphomatous disease, primary lymphoma of the cervix is very uncommon; however, this entity can occasionally be distinguished from cervical carcinoma by means of MRI. This is an important fact as treatment and prognosis differ between these neoplasms. We present a case of primary cervical lymphoma studied with high-field (1.5 T) MRI and we make an extensive review of the literature. The cervical mass was found in a routine pelvic examination in a patient with no previous history of gynecologic disorders. This is an uncommon way of presentation of this disease. T2-weighted turbo spin-echo (TSE) sequences in the axial, sagittal, and coronal planes, and T1-weighted SE pre- and post-contrast images, were obtained. The lack of involvement of the mucosa, as well as sparing of cervical stroma and uterine junctional zone, are the most important findings to differentiate cervical lymphoma from carcinoma, and are best evaluated with T2 TSE sequences. Post-contrast images help to delineate the extent of the disease. (orig.)

    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.

    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.

    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 human uterus has no pacemaker or motor innervation, yet develops rhythmic, powerful contractions that increase intrauterine pressure to dilate the cervix and force the fetus through the pelvis. To achieve the synchronous contractions required for labor, the muscle cells of the uterus act as independent oscillators that become increasingly coupled by gap junctions toward the end of pregnancy. The oscillations are facilitated by changes in resting membrane potential that occur as pregnancy progresses. Reductions of potassium channels in the myocyte membranes in late pregnancy prolong myocyte action potentials, further facilitating transmission of signals and recruitment of neighboring myocytes. Late in pregnancy prostaglandin production increases leading to increased myocyte excitability. Also late in pregnancy myocyte actin polymerizes allowing actin-myosin interactions that generate force, following myocyte depolarization, calcium entry, and activation of myosin kinase. Labor occurs as a consequence of the combination of increased myocyte to myocyte connectivity, increased depolarizations that last longer, and activated intracellular contractile machinery. During labor the synchronous contractions of muscle cells raise intrauterine pressure to dilate the cervix in a process distinct from peristalsis. The synchronous contractions occur in a progressively larger region of the uterine wall. As the size of the region increases with increasing connectivity, the contraction of that larger area leads to an increase in intrauterine pressure. The resulting increased wall tension causes myocyte depolarization in other parts of the uterus, generating widespread synchronous activity and increased force as more linked regions are recruited into the contraction. The emergent behavior of the uterus has parallels in the behavior of crowds at soccer matches that sing together without a conductor. This contrasts with the behavior of the heart where sequential contractions are

    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). With 2.23 ± 0.26 kPa, vertical stroke G* vertical stroke of the myometrium was lower in the secretory phase (SP) compared with that of the proliferative phase (PP, vertical stroke G* vertical stroke = 3.01 ± 0.26 kPa). For the endometrium, the value of vertical stroke G* vertical stroke in SP was 68 % lower than during PP (PP, vertical stroke G* vertical stroke = 3.34 ± 0.42 kPa; SP, vertical stroke G* vertical stroke = 1.97 ± 0.34 kPa; p = 0.0061). 3DMMRE produces high-resolution mechanical parameter maps of the uterus and cervix and shows sensitivity to structural and functional changes of the endometrium and myometrium during the menstrual cycle.

    To investigate the accuracy of three-dimensional ultrasound (3D-US) with respect to magnetic resonance imaging (MRI), and compared to clinical examination, in the assessment of cervix and vagina in women with uterine malformations. In this prospective study, 16 patients diagnosed with uterine malformation with cervical involvement underwent 3D-US examination. The acquisition of cervical volumes was transvaginal, with four cases repeated in the peri-ovulation period, while vaginal volumes were acquired by transperineal imaging following filling of the vagina with gel. MRI was performed in 13 patients using endovaginal gel. All cases underwent clinical examination, comprising bimanual gynecological examination and speculoscopy. Diagnostic concordance of each of the methods with the gold standard was calculated. 3D-US cervical examinations revealed 12 cases of duplicate cervix, two of complete septate cervix and two of incomplete septate cervix. Images of the cervical canal in the peri-ovulation period were judged subjectively to be better in quality, but did not lead us to change any diagnosis. 3D-US vaginal examinations revealed four cases with a vaginal dividing wall and two with a blind hemivagina. None of the 3D-US findings contradicted the clinical findings of the cervix; however, clinically we observed two cases with vaginal dividing wall that had not been diagnosed with 3D-US. MRI diagnosed nine cases of duplicate cervix, three of complete septate cervix, one of incomplete septate cervix, five of vaginal dividing wall and two of blind hemivagina. One case diagnosed as complete septate cervix was in fact a duplicate cervix on 3D-US and on clinical examination. Compared with the gold standard, both 3D-US and MRI were highly efficient in the diagnosis of anomalies of the cervix and vagina. The overall diagnostic concordance of 3D-US with clinical examination (kappa, 0.84; 95% CI, 0.62-1) was slightly inferior to that of MRI with clinical examination (kappa, 0

    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

    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.)

Technique and instrumentations. University-based tertiary care hospital. An 18-year-old woman with vaginal agenesis and cervical dysgenesis and a 13-year-old woman with vaginal agenesis and cervical agenesis, both patients with a functional uterus. Creation of a neovagina by vaginal procedure and laparoscopically assisted biomaterial graft for uterovaginal anastomosis was performed in all patients. All surgical findings were carefully reviewed to determine the anatomic characteristics of the malformed cervix. Subsequent follow-up was done by referring physicians. Uterovaginal continuity was established successfully in both patients, and all of the women were menstruating normally. Granulomatous polyps occurred in one patient, and this condition was successfully managed. At 6-month follow-up, mean vaginal length was 12 cm and ≥ 80% of neovaginal epithelium was iodine positive in both patients. Unimpeded menstrual flow continued after 4 years of follow-up in one patient and 5 years of follow-up in the other patient. A combined laparoscopic and vaginal procedure with biomaterial graft could be an effective alternative in selected women with atresia of cervix and vagina.

We describe a case of immature teratoma which occurred primarily in the uterus in a 56-year-old female. Treatment consisted of total simple hysterectomy. Three months after surgery, the patient relapsed with voluminous pelvic mass and was treated with bleomycin, etoposide, and cisplatin-containing chemotherapy regimen. Conclusion. In this report and according to the pertinent literature, clinical and pathological features and management of uterine immature teratomas are discussed. The mainstay of treatment is surgery. The prognosis of this unusual disease remains uncertain.

    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

    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

  13. Estradiol and progesterone regulate the migration of mast cells from the periphery to the uterus and induce their maturation and degranulation.

    Directory of Open Access Journals (Sweden)

    Federico Jensen

    Full Text Available BACKGROUND: Mast cells (MCs have long been suspected as important players for implantation based on the fact that their degranulation causes the release of pivotal factors, e.g., histamine, MMPs, tryptase and VEGF, which are known to be involved in the attachment and posterior invasion of the embryo into the uterus. Moreover, MC degranulation correlates with angiogenesis during pregnancy. The number of MCs in the uterus has been shown to fluctuate during menstrual cycle in human and estrus cycle in rat and mouse indicating a hormonal influence on their recruitment from the periphery to the uterus. However, the mechanisms behind MC migration to the uterus are still unknown. METHODOLOGY/PRINCIPAL FINDINGS: We first utilized migration assays to show that MCs are able to migrate to the uterus and to the fetal-maternal interface upon up-regulation of the expression of chemokine receptors by hormonal changes. By using a model of ovariectomized animals, we provide clear evidences that also in vivo, estradiol and progesterone attract MC to the uterus and further provoke their maturation and degranulation. CONCLUSION/SIGNIFICANCE: We propose that estradiol and progesterone modulate the migration of MCs from the periphery to the uterus and their degranulation, which may prepare the uterus for implantation.

    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.

    To study the cesarean rate between expectant management and immediate induction in the otherwise uncomplicated postterm pregnancy with favorable cervix. A total of 249 women with uncomplicated pregnancies at 41 weeks plus 3 days (290 days) with favorable cervix (Bishop score > or =6) were randomized to either expectant management (n=125) or immediate induction of labor (n=124). The women in the induction group were sent to labor ward for induction by artificial rupture of membranes (ARM) and/or oxytocin infusion. The women with expectant management had nonstress test (NST) and amniotic fluid index (AFI) performed once a week and twice a week after 43 weeks of gestation until spontaneous labor. The cesarean rate was not different between expectant management and immediate induction (21.6% versus 26.6%; P=0.36). Ninety-five percent of the expectant group delivered within 1 week after enrollment, and all of them delivered within 9 days after randomization. Maternal and fetal complications in both groups were not different. There was also no difference in the mean birth weight (P=0.24) and the frequency of macrosomia (birth weight > or = 4000 g) between the two groups (P=0.23). Cesarean section rate between expectant management and immediate induction in the otherwise uncomplicated postterm pregnancy with favorable cervix was not different. Due to the very low adverse perinatal outcome, both expectant management and immediate induction are acceptable.

    A 31-year-old woman, gravida 2 para 1, visited our clinic for routine follow-up at 20 weeks' gestation. Although she had no abdominal pain or pressure, digital vaginal examination revealed dilatation of the internal cervical os of 1.5 cm, and transvaginal sonography demonstrated dynamic changes in the shape of the cervical canal. The patient underwent Shirodkar's operation. Routine postoperative assessment of the cervix with transvaginal sonography showed dynamic dilatation of the upper cervix (above the cerclage), which was accompanied by a sensation of pelvic pressure but no apparent uterine contractions. A healthy male infant weighing 2,980 g was delivered at 38 weeks' gestation.

    Full Text Available BACKGROUND: Preterm labor, failure to progress, and postpartum hemorrhage are the common causes of maternal and neonatal mortality or morbidity. All result from defects in the complex mechanisms controlling labor, which coordinate changes in the uterine fundus, lower segment, and cervix. We aimed to assess labor-associated gene expression profiles in these functionally distinct areas of the human uterus by using microarrays. METHODS AND FINDINGS: Samples of uterine fundus, lower segment, and cervix were obtained from patients at term (mean +/- SD = 39.1 +/- 0.5 wk prior to the onset of labor (n = 6, or in active phase of labor with spontaneous onset (n = 7. Expression of 12,626 genes was evaluated using microarrays (Human Genome U95A; Affymetrix and compared between labor and non-labor samples. Genes with the largest labor-associated change and the lowest variability in expression are likely to be fundamental for parturition, so gene expression was ranked accordingly. From 500 genes with the highest rank we identified genes with similar expression profiles using two independent clustering techniques. Sets of genes with a probability of chance grouping by both techniques less than 0.01 represented 71.2%, 81.8%, and 79.8% of the 500 genes in the fundus, lower segment, and cervix, respectively. We identified 14, 14, and 12 those sets of genes in the fundus, lower segment, and cervix, respectively. This enabled networks of co-regulated and co-expressed genes to be discovered. Many genes within the same cluster shared similar functions or had functions pertinent to the process of labor. CONCLUSIONS: Our results provide support for many of the established processes of parturition and also describe novel-to-labor genes not previously associated with this process. The elucidation of these mechanisms likely to be fundamental for controlling labor is an important prerequisite to the development of effective treatments for major obstetric problems

    Full Text Available Abstract Background Cervical ripening is a prerequisite for a normal obstetrical outcome. This process, including labor, is a painful event that shares features with inflammatory reactions where peripheral nociceptive pathways are involved. The capsaicin and heat receptor TRPV1 is a key molecule in sensory nerves involved in peripheral nociception, but little is known regarding its role in the pregnant uterus. Therefore, the aim of this study was to investigate human corpus and cervix uteri during pregnancy and labor and non-pregnant controls for the presence of TRPV1. Methods We have investigated human uterine corpus and cervix biopsies at term pregnancy and parturition. Biopsies were taken from the upper edge of the hysterotomy during caesarean section at term (n = 8, in labor (n = 8 and from the corresponding area in the non-pregnant uterus after hysterectomy (n = 8. Cervical biopsies were obtained transvaginally from the anterior cervical lip. Serial frozen sections were examined immunohistochemically using specific antibodies to TRPV1 and nerve markers (neurofilaments/peripherin. Results In cervix uteri, TRPV1-immunoreactive fibers were scattered throughout the stroma and around blood vessels, and appeared more frequent in the sub-epithelium. Counts of TRPV1-immunoreactive nerve fibers were not significantly different between the three groups. In contrast, few TRPV1-immunoreactive fibers were found in nerve fascicles in the non-pregnant corpus, and none in the pregnant corpus. Conclusion In this study, TRPV1 innervation in human uterus during pregnancy and labor is shown for the first time. During pregnancy and labor there was an almost complete disappearance of TRPV1 positive nerve fibers in the corpus. However, cervical innervation remained throughout pregnancy and labor. The difference in TRPV1 innervation between the corpus and the cervix is thus very marked. Our data suggest that TRPV1 may be involved in pain mechanisms associated with

    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.

    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)

    To evaluate local control and toxicity by use of a method of adaptive cervical brachytherapy (ACB). From 1998 to 2008, we identified 65 cervical cancer patients with FIGO (International Federation of Gynecology and Obstetrics) Stage IB1-IVA disease who received definitive external beam radiation therapy and high-dose rate brachytherapy with tandem and ovoid applicators. As tumors regressed, 45 of 65 patients had the tandem source retracted from the uterine fundus at successive brachytherapy insertions, thus decreasing the number of (192)Ir dwell positions. Tests of trend and Fisher's exact test were used to identify the effect of ACB on disease control and toxicity. Kaplan-Meier analyses were performed to evaluate disease control and late complications. The median follow-up was 24.5 months. Of the patients, 92% received chemotherapy. The 3-year overall survival, 3-year disease-free survival, 3-year distant metastasis-free survival, and local control rates were 67%, 76%, 79%, and 97%, respectively. There was only 1 isolated local failure, and there were no local failures beyond 1 year. Distant failure was involved in 93% of recurrences. No significant trend was identified regarding the extent of retraction of the tandem source start position with either failure or toxicity. Acute and actuarial 3-year late Grade 3 toxicity or greater occurred in 24.6% and 17% of patients, respectively. ACB determined by clinical response yielded excellent local control rates. These data indicate that ACB may be useful in decreasing late toxicities from high-dose rate brachytherapy. With the advent of three-dimensional image-guided brachytherapy, additional methods to adapt treatment technique to changes in tumor volume warrant investigation. Copyright (c) 2010 Elsevier Inc.

    To evaluate acute toxicities in cervix cancer patients receiving intensity modulated whole pelvic radiation therapy (IM-WPRT). Between August 2004 and April 2006, 17 patients who underwent IM-WPRT were analysed. An intravenous contrast agent was used for radiotherapy planning computed tomography (CT). The central clinical target volume (CTV) included the primary tumor, uterus, vagina, and parametrium. The nodal CTV was defined as the lymph nodes larger than 1 cm seen on CT and the contrased-enhanced pelvic vessels. The planning target volume (PTV) was the 1-cm expanded volume around the central CTV, except for a 5-mm expansion from the posterior vagina, and the nodal PTV was defined as the nodal CTV plus a 1.5 cm margin. IM-WPRT was prescribed to deliver a dose of 50 Gy to more than 95% of the PTV. Acute toxicity was assessed with common toxicity criteria up to 60 days after radiotherapy. Grade 1 nausea developed in 10 (58.9%) patients, and grade 1 and 2 diarrhea developed in 11 (64.7%) and 1 (5.9%) patients, respectively. No grade 3 or higher gastrointestinal toxicity was seen. Leukopenia, anemia, and thrombocytopenia occurred in 15 (88.2%). 7 (41.2%), and 2 (11.8%) patients, respectively, as hematologic toxicities. Grade 3 leukopenia developed in 2 patients who were treated with concurrent chemoradiotherapy. IM-WPRT can be a useful treatment for cervix cancer patients with decreased severe acute toxicities and a resultant improved compliance to whole pelvic irradiation.

    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.

    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 Uterine incarceration is an uncommon but serious presentation in the emergency department that requires early recognition to improve maternal and fetal outcomes.Case: A 29-year-old female, at 12 weeks gestation, presented to the emergency department (ED with complaints of fever, sacral pain and urgency. Based on history and physical examination, she was found to have a retroverted, incarcerated uterus. After a failed attempt at reduction in the ED, her uterus was successfully reduced under general anesthesia.Discussion: Pain and urinary difficulties, such as retention and hesitancy, are frequent in pregnancy, yet incarcerated uterus is an uncommon emergency department diagnosis that often presents with these symptoms. Clues to the diagnosis include a retroverted uterus, urinary retention, and pain in a patient presenting in the third to fourth months of gestation. Treatment is by manual reduction of the uterus. Complications range from spontaneous abortion to uterine rupture.[WestJEM. 2008;9:232-234.

    A 71-year-old patient presented with very painful ulcers after uterus-resection with the da Vinci® Surgical System 3 months before. The anamnesis revealed that in the past 10 months similar wounds had appeared after osteosynthesis of a humerus fracture and after breast biopsy. The patient had been unsuccessfully treated with different antibiotics and wound dressings for several months for a suspected superinfected, postoperative disturbed wound healing. None of the wounds became smaller or healed completely. After exclusion of relevant differential diagnoses pyoderma gangrenosum (PG) could be diagnosed and systemic immunosuppressive therapy was initiated. The pain improved rapidly and complete wound healing was achieved. Pyoderma gangrenosum is a rarely diagnosed autoimmune disease which often occurs after physical trauma such as surgical interventions. Because a correct diagnose is usually made late it is important to be aware of this disease to treat it early and correctly.

    Sixty-three properly selected patients with sterility due to uterus bicornis underwent operations to restore fertility, Of these 63, 12 suffered from primary sterility and 51 from secondary sterility. The 51 patients with secondary sterility had had a total of 127 pregnancies before operation. Of these 127 pregnancies, 122 ended in early or late abortion and five in premature delivery, giving 5 live births and a fetal wastage rate of 96%. Of the 63 patients, 42 became pregnant after operation. Of these 42, 14 had more than one pregnancy. The total number of pregnancies was 59. Of these, 32 went to term, 15 ended prematurely and 12 ended in abortion. The 59 pregnancies resulted in 45 live births. Fetal wastage dropped from 96% before operation to 23.7% after operation.

    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.

    A voluntary screening of uterus cervix cancer took place in Kossodo health district from February 1st 2001 to April 30th 2002. It involved the age-group women of 25 to 59 years. This study included 239 women given a participation rate of 6.8%. We had sampled young women in three categories with average age of 38 years: a) doing a remunerated job (64.9%); b) mostly educated (85.3%); and c) married (86.2%). The visual inspection was the method used after the application of 4% acetic acid followed by that of lugol. In all 74 biopsies have been undertaken. Furthermore, we have noticed a 4.2% prevalence of pre-cancerous injuries. The cancerous lesions represented 2.5% of the sampling and the inflammatory lesions 13.4%. VPH infection was found on 2.5% samples and condylomatous injuries in 5% cases. This experience would deserve to be carried out always and a cervix cancer screening campaign held at national level.

    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 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.

  17. The structure and function of the cervix during pregnancy

    2016-03-01

    Full Text Available The structure of the cervix is integral to the maintenance of pregnancy, keeping the developing baby in utero and forming a barrier to the ascent of microorganisms from the vagina. Weakness of the cervix may lead to deficiency of this barrier and is associated with subsequent preterm birth. The underlying cause of this structural weakness is poorly understood. In this paper we review the structure and function of the cervix before and during pregnancy. The causes of mechanical failure of the cervix during pregnancy are described, with a specific focus on the internal cervical os. We highlight the role of the internal cervical os in causing preterm birth and discuss research techniques that may provide further insight into its function during pregnancy. It is hoped that clinical translation of this knowledge will enable the early and appropriate identification of women who will benefit from strategies to reinforce the internal os and so reduce the incidence of preterm birth.

    Full Text Available Adenosarcoma is a rare tumor which consists of benign glandular epithelium and malignant mesenchymal component. Here we report a case of adenosarcoma of the uterine corpus. Case Presentation. A 59-year-old woman presented with vaginal bleeding and visited a local clinic. She had a uterine tumor pointed out and was referred to our hospital. Ultrasound scans revealed a large heterogeneous mass occupying the whole uterine cavity. Cytological test of endometrium was performed but the result was negative. A fractional endometrial curettage revealed no malignancy. Magnetic resonance imaging (MRI revealed a heterogeneous solid tumor of 77 × 76 mm. Total abdominal hysterectomy with bilateral salpingo-oophorectomy and pelvic lymphadenectomy was performed. On gross examination, the tumor was arising from the uterine body and occupied the whole uterine cavity. Histopathological examination revealed phyllodes-like architecture on low magnification and periglandular cuffing of tumor cells. The lesion was confined to the uterus. Histopathological final diagnosis was adenosarcoma. Her postoperative course was uneventful and she was discharged without postoperative treatment and remains alive without disease 6 months after the surgery.

    Background The isoflavone genistein (GEN) is found in soy (Glycine max) and red clover (Trifolium pratense). The estrogenic activity of GEN is known, and it is widely advertised as a phytoestrogen useful in alleviating climacteric complaints and other postmenopausal disorders. Knowledge of effects of long-term administration of GEN in laboratory animals is scarce, and effects in the uterus and mammary gland after long-term administration have not been studied. The uterus and mammary gland are known to be negatively influenced by estrogens used in hormone therapy. Objectives We administered two doses of GEN [mean daily uptake 5.4 (low) or 54 mg/kg (high) body weight (bw)] orally over a period of 3 months to ovariectomized (ovx) rats and compared the effects with a treatment with two doses of 17β-estradiol [E2; 0.17 (low) or 0.7 mg/kg bw (high)]. Mammary glands, vaginae, and uteri were investigated morphologically and immunohistochemically. We quantified the expression of proliferating cell nuclear antigen (PCNA) and progesterone receptor (PR) in the mammary gland. Results In rats treated with either of the E2 doses or the high GEN dose, we found increased uterine weight, and histologic analysis showed estrogen-induced features in the uteri. In vaginae, either E2 dose or GEN high induced hyperplastic epithelium compared with the atrophic controls. In the mammary gland, E2 (either dose) or GEN increased proliferation and PR expression. Serum levels of luteinizing hormone were decreased by E2 (both doses) but not by GEN. Conclusions In summary, E2 and GEN share many effects in the studied organs, particularly in the vagina, uterus, and mammary gland but not in the hypothalamo/pituitary unit. PMID:18174952

    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. The uterus doses during thoracic CT were determined by measuring organ doses using an Alderson-RANDO®-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. 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 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 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. Our findings demonstrate that protective aprons are an effective dose reduction technique without additional costs and little effect on patient examination time. © Georg Thieme Verlag KG Stuttgart · New York.

  2. 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.

    Cervicography is a technique for visual screening of uterine cervix images for cervical cancer. One of our research goals is the automated detection in these images of acetowhite (AW) lesions, which are sometimes correlated with cervical cancer. These lesions are characterized by the whitening of regions along the squamocolumnar junction on the cervix when treated with 5% acetic acid. Image preprocessing is required prior to invoking AW detection algorithms on cervicographic images for two reasons: (1) to remove Specular Reflections (SR) caused by camera flash, and (2) to isolate the cervix region-of-interest (ROI) from image regions that are irrelevant to the analysis. These image regions may contain medical instruments, film markup, or other non-cervix anatomy or regions, such as vaginal walls. We have qualitatively and quantitatively evaluated the performance of alternative preprocessing algorithms on a test set of 120 images. For cervix ROI detection, all approaches use a common feature set, but with varying combinations of feature weights, normalization, and clustering methods. For SR detection, while one approach uses a Gaussian Mixture Model on an intensity/saturation feature set, a second approach uses Otsu thresholding on a top-hat transformed input image. Empirical results are analyzed to derive conclusions on the performance of each approach.

    Full Text Available A mesonephric adenocarcinoma of the cervix is a very rare tumor deriving from remnants of the mesonephric duct. Differential diagnosis from other cervical carcinomas is difficult and little is known regarding its biological behavior, prognosis, and the optimal management strategy. We present a case of a mesonephric adenocarcinoma of the cervix with a comprehensive review of the existing literature. In this case a 66-year-old woman presented with postmenopausal vaginal bleeding. She was diagnosed with a FIGO stage IIB mesonephric adenocarcinoma of the cervix and treated with neoadjuvant chemoradiotherapy and a Wertheim hysterectomy. The recovery from surgery was uneventful and the patient remains with no evidence of disease with 2 years of follow-up.

    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 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.

    2015-02-01

    A 21-year-old woman with history of presacral ganglioneuroblastoma underwent I-MIBG scan for restaging. Planar images revealed increased MIBG activity in the upper pelvis, suggestive of disease recurrence. Complementary SPECT/CT images, however, localized the activity to the uterine cervix. Upon further questioning, it has been established that the patient was menstruating. Subsequent follow-up scans proved normal, confirming the benign etiology of these findings. The case shows that radioactive blood accumulation in the uterine cervix can interfere with MIBG scan interpretation in menstruating patients.

    Uterus bicornuate unicollis is one of the various congenital abnormalities of the female genital tract caused by partial fusion of the mullerian ducts on both sides. A case of acute abdomen resulting from missed diagnosed bicornuate unicollis uterus in a 42-year infertile women was presented. The ultrasonographic diagnosis of twisted complex left adnexial cyst was made prior to exploratory laparotomy. However, findings at laparotomy revealed a non-communicating bicornuate unicollis uterus with damaged right tube (hyrosalpinx) and normal ovaries and left tube. A blind-ended rudimentary left sided uterine horn was excised with the ovary spared and the right sided hydrosalpinx disconnected using chromic 1. Patient was however counselled for in vitro fertilization.

    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.

    Rupture of a pregnant uterus occurs most often in a scarred uterus, and spontaneous rupture of a non-scarred uterus in the early second trimester is rare. A woman with two previous normal vaginal deliveries and no prior trauma to the uterus presented at 16 weeks' gestation with an acute abdomen due to intraperitoneal hemorrhage. A large rupture of the fundus of the uterus was found. A supracervical hysterectomy was carried out, with subsequent good recovery. The specimen showed placenta percreta. Spontaneous rupture of an unscarred uterus, due to placenta percreta, should be considered in cases of acute intraperitoneal hemorrhage, even in early pregnancy.

    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.

    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

    2001-01-01

    Full Text Available Objective: To assess the prognostic value of DNA‐image cytometry in cervical carcinoma of the uterus and its relation to other established prognostic factors. Study design: The study included 116 cases of cervical carcinoma FIGO stages IB and II which were treated with radical abdominal hysterectomy. The median follow‐up was 55 months (range 1–162 months. DNA image cytometry was performed on cytologic specimens prepared by enzymatic cell separation from formalin‐fixed, paraffin‐embedded tissues. DNA stemline ploidy, DNA stemline aneuploidy, 5c exceeding rate, 9c exceeding rate, 2c deviation index, and DNA malignancy grade were computed. DNA‐variables as well as various clinical and histological variables were related to survival rates. Results: In multivariate statistical analysis DNA stemline ploidy using 2.2c as a cut‐off value and FIGO stage showed to be statistically significant available presurgery predictors of survival, whereas the postsurgical parameters lymphonodal status, tumor size and parametrial involvement were significantly correlated with survival. The synopsis of all parameters in a multivariate Cox model indicated that – with declining relevance – the number of positive pelvic lymph nodes, DNA stemline ploidy using a cut‐off level at a modal value of 2.2c, largest pelvic lymph node, 5c exceeding rate, and ratio of carcinoma area to cervix area, were of predictive value for survival. Conclusions: Our results suggest that prognostic information deducted from classical staging parameters is successfully complemented by DNA image cytometry which can be applied pretherapeutically.

    The objectives of this report are, first, to describe the clinical behavior of cases of carcinoma metastatic to the uterine cervix treated at our institution in order to carry out a systematic review to establish the behavioral patterns of the most frequent metastases to the cervix and, second, to generate guidelines for their diagnosis and treatment. At the National Institute of Cancer of Mexico (INCan), we performed a review of the clinical files with a diagnosis of malignant neoplasm metastatic to the uterine cervix between 1990 and 2009. For a systematic review, we conducted a PubMed search between the years 1970 and 2009 of case reports and series of cases of patients with metastatic gastric, breast, ovarian and colorectal cancer. We analyzed each report individually and extracted the patients' clinical data from our cases and reports, including the primary tumor, cervical metastases and survival rates. There were 10 cases of tumors metastatic to the uterine cervix. Metastasis was documented in one-half of the patients during follow up, with two of these cases having the cervix as the only site. We included the following reports in the systematic review: 13 reports of gastric-associated cancer, 30 related to breast cancer, nine with ovarian-associated cancer and 10 related to colorectal cancer. Metastatic cervical activity is an infrequent event. The prognosis of survival is poor in the presence of gastric or ovarian cancer and cervical metastases. © 2012 The Authors.

    2015-01-01

    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.

  19. Hysteroscopic intervention in septate uterus and intrauterine synechiae

    2013-02-01

    Full Text Available Three-dimensional transvaginal ultrasonography was used to diagnose a septate uterus in a 24-year-old woman with infertility for 2 years. On infertility workup, semen analysis of her husband also revealed oligoasthenoteratospermia. Hysteroscopic metroplasty was performed successfully to resolve the uterine septum; however, subsequent in vitro fertilization and intracytoplasmic sperm injection yielded a blighted ovum requiring dilatation and curettage. After curettage, the patient had hypomenorrhea secondary to intrauterine synechiae and was treated with a hysteroscopic resectoscope and lysis of adhesions. Following these procedures, assisted reproductive technology was again implemented and resulted in a successful pregnancy. In our experience, three-dimensional transvaginal ultrasonography is a noninvasive, accurate, and easy method for the diagnosis of Müllerian duct anomalies, including septate uterus. Hysteroscopic metroplasty helps to normalize intrauterine cavity architecture. Additionally, it is important to repeat hysteroscopic examination when intrauterine adhesions are highly suspected.

    Full Text Available Female genital tuberculosis remains as a major cause of tubal obstruction leading to infertility, especially in developing countries. The global prevalence of genital tuberculosis has increased during the past two decades due to increasing acquired immunodeficiency syndrome. Genital tuberculosis (TB is commonly asymptomatic and it is diagnosed during infertility investigations. Despite of recent advances in imaging tools such as computed tomography (CT scan, magnetic resonance imaging (MRI and ultrasongraphy, hysterosalpingography has been considered as the standard screening test for evaluation of tubal infertility and as a valuable tool for diagnosis of female genital tuberculosis. Tuberculosis gives rise to various appearances on hysterosalpingography (HSG from non-specific changes to specific findings. The present pictorial review illustrates and describes specific and non-specific radiographic features of female genital tuberculosis in two parts. Part I presents specific findings of tuberculosis related to tubes such as "beaded tube", "golf club tube", "pipestem tube", "cobble stone tube" and the "leopard skin tube". Part II will describe adverse effects of tuberculosis on structure of endometrium and radiological specific findings, such as "T-shaped" tuberculosis uterus, "pseudo-unicornuate "uterus, "collar-stud abscess" and "dwarfed" uterus with lymphatic intravasation and occluded tubes which have not been encountered in the majority of non-tuberculosis cases.

    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.

  2. Designing artificial environments for preterm infants based on circadian studies on pregnant uterus

    Directory of Open Access Journals (Sweden)

    Shimpei eWatanabe

    2013-09-01

    Full Text Available Using uterine explants from Per1::Luc rats and in situ hybridization, we recently reported that the circadian property of the molecular clock in the uterus and placenta is stably maintained from non-pregnancy, right through to the end stage of pregnancy under regular light-dark cycles. Despite long-lasting increases in progesterone during gestation and an increase in estrogen before delivery, the uterus keeps a stable Per1::Luc rhythm throughout the pregnancy. The study suggests the importance of stable circadian environments for fetuses to achieve sound physiology and intrauterine development. This idea is also supported by epidemiological and rodent studies, in which pregnant females exposed to repeated shifting of the light-dark cycles have increased rates of reproductive abnormalities and adverse pregnancy outcomes. Leading from this, we introduced artificial circadian environments with controlled lighting conditions to human preterm infants by developing and utilizing a specific light filter which takes advantage of the unique characteristics of infants’ developing visual photoreceptors. In spite of growing evidence of the physiological benefits of nighttime exposure to darkness for infant development, many Japanese Neonatal Intensive Care Units (NICUs still prefer to maintain constant light in preparation for any possible emergencies concerning infants in incubators. To protect infants from the negative effects of constant light on their development in the NICU, we have developed a new device similar to a magic mirror, by which preterm infants can be shielded from exposure to their visible wavelengths of light even in the constant light conditions of the NICU while simultaneously allowing medical care staff to visually monitor preterm infants adequately. The device leads to significantly increased infant activity during daytime than during night time and better weight gains.

  3. Hedgehog signaling plays roles in epithelial cell proliferation in neonatal mouse uterus and vagina.

    2012-04-01

    Both the uterus and vagina develop from the Müllerian duct but are quite distinct in morphology and function. To investigate factors controlling epithelial differentiation and cell proliferation in neonatal uterus and vagina, we focused on Hedgehog (HH) signaling. In neonatal mice, Sonic hh (Shh) was localized in the vaginal epithelium and Indian hh (Ihh) was slightly expressed in the uterus and vagina, whereas all Glioma-associated oncogene homolog (Gli) genes were mainly expressed in the stroma. The expression of target genes of HH signaling was high in the neonatal vagina and in the uterus, it increased with growth. Thus, in neonatal mice, Shh in the vaginal epithelium and Ihh in the uterus and vagina activated HH signaling in the stroma. Tissue recombinants showed that vaginal Shh expression was inhibited by the vaginal stroma and uterine Ihh expression was stimulated by the uterine stroma. Addition of a HH signaling inhibitor decreased epithelial cell proliferation in organ-cultured uterus and vagina and increased stromal cell proliferation in organ-cultured uterus. However, it did not affect epithelial differentiation or the expression of growth factors in organ-cultured uterus and vagina. Thus, activated HH signaling stimulates epithelial cell proliferation in neonatal uterus and vagina but inhibits stromal cell proliferation in neonatal uterus.

    Currently, CT has been widely used for HDR planning as MRI is not widely available for tumor imaging. Conventional pear-shaped isodose distribution may not be discarded completely because of possible microscopic diseases into parametrium/uterus. For patients with small uterus, organs at risk (OARs) can fall inside 100% conventional pear-shaped isodose-line. This study compares two pear-shaped based dose optimization methods for OARs sparing. Seven cervical cancer patients with small uterus were evaluated using 2 methods. For Method A, with conventional dwell-time loading, point A lateral distance was reduced until all OARs' D2cc were within the dose limits. For Method B, a reference target volume was generated using conventional pear-shaped 100% isodose- surface. While isodose-line near the point A was adjusted for OARs sparing, isodose-line surrounding ovoids were optimized to match the reference target volume. For equivalent OAR sparing, 100% isodose-line width (lateral dimension) at 1 cm inferior to point A (-1 cm) and at across centers of ovoids (ovoid) were compared between the 2 methods. OARs fall inside conventional 100% isodose-line in all cases. Median position of hot spots was 0.2 cm (range -;1.2 to 2.9 cm) superior to point A. Using Method A, point A lateral distance was adjusted to 1.4-1.7 cm for OARs sparing. Median width of 100% isodose-line was 5.82 cm at ovoid level, and 4.50 cm at -1 cm level. At ovoid level, median width of 100% isodose-line was reduced by 9(8-13)% for Method A, and was unchanged for Method B. At -1 cm level, median width of 100% isodose-line was reduced by 19(2- 33)% for Method A, and 11(0-15)% for Method B. for patients with small uterus, OARs are often fall inside 100% pear-s haped isodose-line near point A level. OARs can be spared without dramatically compromise treatment volume coverage around cervix using Method B. © 2012 American Association of Physicists in Medicine.

    The potential utilization of plant secondary metabolites possessing estrogenic properties as alternatives to the classical hormone replacement therapy (HRT) for the relief of postmenopausal complaints asks for an evaluation regarding the safety in reproductive organs. In order to contribute to the estimation of the safety profile of the flavanones naringenin (Nar), 8‑prenylnaringenin (8PN) and 6‑(1,1‑dimethylally) naringenin (6DMAN), we investigated uterus and vagina derived from a three‑day uterotrophic assay in rats. Also, we investigated the metabolite profile resulting from the incubation of the three substances with liver microsomes. While no metabolites were detectable for naringenin, hydroxylation products were observed for 8PN and 6DMAN after incubation with human as well as rat liver microsomes. The parent compound naringenin did not evoke any estrogenic responses in the investigated parameters. A significant increase of the uterine wet weight, uterine epithelial thickness and proliferating vaginal cells was observed in response to 8PN, questioning the safety of 8PN if applied in the human situation. In contrast, no estrogenic effects on the reproductive organs were observed for 6DMAN in the conducted study, rendering it the compound with a more promising safety profile, therefore justifying further investigations into its efficacy to alleviate postmenopausal discomforts.

    Full Text Available Coriocarcinomas geralmente ocorrem no corpo uterino durante o período reprodutivo. Raramente podem acontecer alterações de localização e de idade de acometimento. Coriocarcinomas primários do colo uterino são extremamente raros, geralmente ocorrem no pós-parto de seis meses a dois anos e se apresentam com sangramento por via vaginal. Existem três teorias para o desenvolvimento dos coriocarcinomas no colo uterino: 1 a paciente ter tido uma gestação cervical que sofreu transformação maligna; 2 que o coriocarcinoma da cérvice seja uma metástase de um tumor primário do corpo que desapareceu; 3 que seu desenvolvimento seja devido ao transporte de células coriônicas da gestação precedente como êmbolos, os quais ficaram latentes e posteriormente sofreram transformação maligna. A terapêutica preconizada é a realização de histerectomia com manutenção dos anexos e posterior quimioterapia. Relatamos o caso de uma mulher de 34 anos que, seis meses após parto normal, iniciou com sangramento vaginal. O exame especular mostrou massa vegetante e hemorrágica do colo uterino e a dosagem de gonadotrofina coriônica humana fração b (b-HCG revelou altos níveis sangüíneos. O exame histopatológico mostrou uma neoplasia maligna composta por sincício e citotrofoblasto malignos comprometendo apenas o colo uterino. Nosso caso é um coriocarcinoma ectópico e acreditamos que seu desenvolvimento no colo uterino seja devido ao transporte de células coriônicas da gravidez precedente que sofreram posterior transformação maligna.Choriocarcinomas usually occur within the body of the uterus during reproductive years.

    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 questioning 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 discharge, 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 questionaires and 49% by questioning by doctors. 6. Pains on sexual intercourse were found in 69% by questionaires and 49% by questionning by doctors. Most pains occurred at penis insertion and was thought to be due to atrophy and inflammation of vagina and external genitalia in most cases. 7. Both vaginal damage 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.

    Müllerian anomalies are often associated with urinary tract anomalies. Herlyn-Werner-Wunderlich syndrome or obstructed hemivagina and ipsilateral renal anomaly are rare Müllerian anomaly comprising uterine didelphys, obstructed hemivagina, and ipsilateral renal anomaly. We report an unusual case of uterus didelphys with obstructed hemivagina and contralateral (not ipsilateral) multicystic dysplastic kidney. An early diagnosis is critical to prevent complications such as adhesions with subsequent infertility. A careful evaluation of the female reproductive tract may be necessary in children with not only renal aplasia but also lateral renal anomalies such as multicystic dysplastic kidney.

    To investigate the relationship between folate in serum, red blood cell (RBC), cervix cancerization, as well as the interaction between folate deficiency and HPV16 infection in cervix cancerization. 254 samples were selected from the patients who were newly pathologically diagnosed of having cervix inflammation (CI), low-grade cervical intraepithelial neoplasia (CIN I), high-grade cervical intraepithelial neoplasia (CIN II/III) and cervical squamous cell carcinoma (SCC). PCR and microbiological assay were adopted to detect HPV infection and folate concentration. Rates of HPV16 infection increased with the severity of cervix cancerization (tend: χ² = 34.96, P cancerization. Both serum and RBC folate deficiency could increase the risk of cervix cancerization, and folate deficiency might have a synergic action with HPV16 in this procession.

    Full Text Available Purpose : To investigate the feasibility of concurrent chemo radiation in locally advanced carcinoma cervix patients in our clinical setting. Materials and Methods : From Sept. 1 st 2005 to Aug. 31 st 2006, 102 patients of carcinoma cervix belonging to stage IIA to IV A were enrolled in the study. External beam radiation therapy was administered using Cobalt 60 teletherapy machine. Cisplatinum (40 mg/m 2 and 5 Fluorouracil (500 mg /m 2 continuous infusions with radiotherapy on D2-D5 in first and last 5 # of radiation therapy were administered. Results : Response to treatment and toxicities were monitored and analyzed in 102 patients (50 study group and 52 control group. All 102 patients completed treatment. Out of 50 patients in the study group, 30, 10 and 4 patients had complete, partial and progressive disease, respectively. While out of 52 patients in the control group, 26 had complete and 12 showed partial response. No difference in overall renal, hematological and cutaneous toxicity was seen between two groups. Conclusion : This study did not show any benefit of concurrent chemo radiation as compared to radiotherapy alone in locally advanced cervical cancer patients. This could be due to more bulk of tumor stage per stage, poor nutritional status, less number of patients in both arms, not enough to pick up statistically significant small difference in outcome.

    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 Reducing maternal mortality constitutes one of the eight Millennium Development Goals. While significant progress has been made, system issues and professional training continue to affect maternal survival, especially when unusual, but deadly, complications arise. This rare case of survival after the rupture of an unscarred uterus in a grand multiparous woman from a remote village in Ghana illustrates how systemic transportation issues and limited access to advanced medical care put women with obstetric complications at risk. The usual clinical presentation of ruptured uteri and methods to prevent this catastrophic event are discussed. This case illustrates the systemic transportation issue that often limits access to prenatal and emergency care throughout much of the developing world and demonstrates how advanced training for emergency nurses and the use of ultrasound diagnosis can expedite difficult diagnoses and lead to maternal survival, even in the most adverse circumstances

    Pelvic floor disorders cover pathologies of which physiopathology is not well understood. However cases get prevalent with an ageing population. Within the context of a project aiming at modelization of the dynamics of pelvic organs, we have developed an efficient segmentation process. It aims at alleviating the radiologist with a tedious one by one image analysis. From a first contour delineating the uterus-vagina set, the organ border is tracked along a dynamic mri sequence. The process combines movement prediction, local intensity and texture analysis and active contour geometry control. Movement prediction allows a contour intitialization for next image in the sequence. Intensity analysis provides image-based local contour detection enhanced by local binary pattern (lbp) texture descriptors. Geometry control prohibits self intersections and smoothes the contour. Results show the efficiency of the method with images produced in clinical routine.

    Microvesicles and exosomes are nanoparticles released from cells and can contain small RNAs, mRNA and proteins that affect cells at distant sites. In sheep, endogenous beta retroviruses (enJSRVs) are expressed in the endometrial epithelia of the uterus and can be transferred to the conceptus trophectoderm. One potential mechanism of enJSRVs transfer from the uterus to the conceptus is via exosomes/microvesicles. Therefore, studies were conducted to evaluate exosomes in the uterine luminal fluid (ULF) of sheep. Exosomes/microvesicles (hereafter referred to as extracellular vesicles) were isolated from the ULF of day 14 cyclic and pregnant ewes using ExoQuick-TC. Transmission electron microscopy and nanoparticle tracking analysis found the isolates contained vesicles that ranged from 50 to 200 nm in diameter. The isolated extracellular vesicles were positive for two common markers of exosomes (CD63 and HSP70) by Western blot analysis. Proteins in the extracellular vesicles were determined by mass spectrometry and Western blot analysis. Extracellular vesicle RNA was analyzed for small RNAs by sequencing and enJSRVs RNA by RT-PCR. The ULF extracellular vesicles contained a large number of small RNAs and miRNAs including 81 conserved mature miRNAs. Cyclic and pregnant ULF extracellular vesicles contained enJSRVs env and gag RNAs that could be delivered to heterologous cells in vitro. These studies support the hypothesis that ULF extracellular vesicles can deliver enJSRVs RNA to the conceptus, which is important as enJSRVs regulate conceptus trophectoderm development. Importantly, these studies support the idea that extracellular vesicles containing select miRNAs, RNAs and proteins are present in the ULF and likely have a biological role in conceptus-endometrial interactions important for the establishment and maintenance of pregnancy.

    Full Text Available Cervix is one of the most common target organ for both non neoplastic and neoplastic lesions of the female genital tract. Cervix cancer is the second most common cancer worldwide having poor prognosis. Inflammatory lesions of clinicopathological importance are acute cervicitis, chronic cervicitis and chronic granulomatous cervicitis. Carcinoma cervix is the commonest malignancy in Indian women Early sexual activity, sexually transmitted diseases, viral infections, low socioeconomic status, injury related to multiple births are the various factors contributing for the carcinoma cervix. Non-infective cervicitis often being chemical in nature that includes chemical irritations secondary to douching or local trauma produced by foreign bodies including tamponsdiaphragms, pessaries and intrauterine contraceptive devices. Studies have shown that chronic granulomatous cervicitis is mostly caused by tuberculosis. __________________________

    Yan Ji

    Full Text Available Uterus development during pre-implantation stage affects implantation process and embryo growth. Aberrant uterus development is associated with many human reproductive diseases. Among the factors regulating uterus development, vascular remodeling promoters are critical for uterus function and fertility. Vascular endothelial growth factor (VEGF, as one of the major members, has been found to be important in endothelial cell growth and blood vessel development, as well as in non-endothelial cells. VEGF mediation in reproduction has been broadly studied, but VEGF-induced transcriptional machinery during implantation window has not been systematically studied. In this study, a genetically repressed VEGF mouse model was used to analyze uterus transcriptome at gestation 2.5 (G2.5 by Solexa/Illumina's digital gene expression (DGE system. A number of 831 uterus-specific and 2398 VEGF-regulated genes were identified. Gene ontology (GO analysis indicated that genes actively involved in uterus development were members of collagen biosynthesis, cell proliferation and cell apoptosis. Uterus-specific genes were enriched in activities of phosphatidyl inositol phosphate kinase, histone H3-K36 demethylation and protein acetylation. Among VEGF-regulated genes, up-regulated were associated with RNA polymerase III activity while down-regulated were strongly related with muscle development. Comparable numbers of antisense transcripts were identified. Expression levels of the antisense transcripts were found tightly correlated with their sense expression levels, an indication of possibly non-specific transcripts generated around the active promoters and enhancers. The antisense transcripts with exceptionally high or low expression levels and the antisense transcripts under VEGF regulation were also identified. These transcripts may be important candidates in regulation of uterus development. This study provides a global survey on genes and antisense transcripts

    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.

The parameters analyzed in the MRI examinations were: precise identification of the cervix; presence of hyposignal at the internal orifice of the cervix; loss of definition of the periendocervical stromal zone (PESZ); presence of hyposignal content inside the amniotic sac (sludge sign) and anatomical and functional biometry of the cervix. Peripheral hyposignal was found in 41 (85.4%) and loss of definition of the PESZ was observed in 36 pregnant women (73.5%) with cervical insufficiency. Sludge was observed in 46 pregnant women with cervical insufficiency, and this was seen on MRI in 27 cases (58.7%). The mean anatomical and functional lengths of the cervix on MRI in the pregnant women with cervical insufficiency were 3.5 ± 0.8 cm (0.8-4.9 cm) and 28.7 ± 6.3 mm (9-41 mm). None of the normal pregnant women presented hyposignal loss of the PESZ and the sludge sign. MRI may be useful for evaluating the cervix and for early identification of signs of cervical insufficiency during pregnancy.

    Full Text Available Uterine health condition plays a very important role in evoking cattle fertility or infertility. The major prerequisites to enhance and achieve postpartum bovine fertility are a normal physiological uterine involution and re-establishment of ovarian cyclicity. Uterine function is usually compromised in cattle by bacterial contamination of the uterine lumen after parturition, and pathogenic bacteria often persist, causing uterine disease, a key cause of infertility in cattle. The causes of uterine diseases are complex and multifactorial; therefore, a broad approach must be taken when trying to identify the causes or prevent them. The dairy cow undergoes a state of negative energy during the transition into lactation, which leads to immunosuppression and increased susceptibility to disease. The main risk factors for uterine diseases are dystocia, stillbirth, abortion, prolapsed uterus, retained placenta. Uterine diseases are associated with lower conception rates, increased intervals from calving to first service or conception, and more cattle culled for failure to conceive. Health and management strategies should be applied to avoid the various risk factors that may affect cattle around parturition and postpartum. This review article will through light on conditions associated with uterine health and disorders and their significance on future fertility of parturient dairy cows.

    Pyometra is a common disease of cattle that causes infertility and thereby financial losses to the cattle industry. Bacteria involved in the development and progression of pyometra have been investigated by microbial culture but their tissue invading abilities, which is an important aspect of bacterial pathogenicity and development of lesions, have not been investigated. Bacterial invasion of the uterus and oviducts was studied in 21 cows diagnosed with pyometra at the time of slaughter by applying fluorescence in situ hybridization using probes targeting 16S ribosomal RNA of Fusobacterium necrophorum, Porphyromonas levii, Trueperella pyogenes and the overall bacterial domain Bacteria. Fusobacterium necrophorum and P. levii were found to invade the endometrium, especially if the endometrium was ulcerated, and penetrated deep into the lamina propria. These species co-localized within the tissue thus indicating a synergism. Trueperella pyogenes did not invade the uterine tissue. In addition to endometrial lesions, most cows with pyometra also had salpingitis but without significant bacterial invasion of the oviductal wall. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Thirty six Etawah-grade does (BW 20.4-44.2 kg, age 2.5-7 years were used to study the efficacy of increasing secretion of endogenous hormones of pregnancy by superovulation of does to stimulate of growth prenatal in uterus. The does were injected with pregnant mare serum gonadotrophin (PMSG, 0 IU/kg BW [grouped into nonsuperovulation-NSO] and 15 IU/kg BW [grouped into Superovulation-SO]. Intravaginal sponge (60 mg medroxyprogesterone acetate was applied for 14 days to synchronize estrus cycle. Twenty four hours prior to sponge removal, PMSG was injected to stimulate superovulation. After sponge removal, five experimental does were mixed with one buck for natural mating. Superovulation prior to mating increased number of corpora lutea, mean of maternal serum estradiol concentration, progesterone concentration, litter size, average birth weight and average milk yield, by 112, 67, 42, 27, 32, and 35%, respectively. Those were correlated with the increase of uterine, corpora lutea, and individual birth weight.

    The innervation of the uterus in the ovoviviparous urodele Salamandra salamandra was studied. In whole mount preparations of the thin-walled uterus of pregnant females, a dense adrenergic network was demonstrated using a modified glyoxylic acid fluorescence technique. Based on vesicle type and cytochemical reactivity after chromate/dichromate fixation for electron microscopy at least two types of neural process were distinguished and classified as adrenergic and cholinergic. Both types are preferentially situated above or between the smooth muscles of the uterine tissue. Adjacent to the muscles in the walls of arterioles mainly adrenergic fibers are seen. Using high performance liquid chromatography with electrochemical detection in tissue homogenates of uterus a considerable amount of noradrenaline could be identified. The significance of the dense innervation is discussed with respect to the function of the uterus during pregnancy and birth.

    Immunocytochemical localization of the basement membrane (BM) proteins laminin, type-IV collagen and fibronectin were analyzed in normal cervical epithelium, low grade squamous intraepithelial lesions (SILs), high grade SILs and invasive squamous cell carcinoma (SCC) of the uterine cervix. A regular, thick and continuous BM was present in normal cervical epithelium and low grade SIL. Interruptions and discontinuity of the BM were more evident in high grade SILs. There was a good correlation between increasing severity of the lesion and increasing number of breaks. In SCC, the distribution of laminin, collagen IV and fibronectin was related to the degree of cellular differentiation, with decreased immunoreactivity being evident in moderately and poorly differentiated tumors. As the invasive potential of the tumor increased, the fragmentation and loss of BM was more evident. Fibronectin showed only moderate to mild immunoreactivity in normal cervical epithelium and low grade SILs. However, the intensity of expression increased in high grade SILs especially in the peritumoral stroma. It may therefore be concluded from these results that snythesis and reabsorption of BM proteins may be related to shifts in cellular metabolism during tumorigenesis.

    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.

    Our previous finding of appreciable quantities of a gastrin-releasing peptide (GRP)-like immunoreactive (GRPLI) entity in ovine fetal and maternal plasma led us to examine the ovine pregnant uterus as a possible source of this material. At term, intense immunohistochemical staining for GRPLI occurred in the endometrial epithelial cells, and the term ovine uterus also contained abundant GRP messenger RNA (mRNA). In contrast, GRP mRNA was not detected in fetal membranes. GRP mRNA was present in the uterus on gestational day 63; a significant increase in GRP mRNA had occurred by day 100. Thereafter, levels remained elevated until term, but 3 months postpartum, GRP mRNA levels were greatly reduced. As previous studies suggested the GRPLI entity to be of greater molecular size than GRP-(1-27), we deduced the primary structure of ovine uterus GRP by sequencing a complementary DNA clone isolated from a complementary DNA library constructed from term ovine uterus polyadenylated RNA. Ovine uterine GRP is composed of 27 amino acid residues and has a conserved C-terminal region, similar to GRP structures in other species. We conclude that during pregnancy, the ovine uterus produces considerable quantities of GRP, which may play an important but hitherto unrecognized role in utero-placental development and possibly in fetal development after transfer to the fetus.

    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.

    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 87cm3. The median delivered V42.75Gy was 1782cm3. 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

    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.

    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.

    Full Text Available Introduction. Papillary squamotransitional cell carcinoma (PSTCC is an uncommon histopathological variant of squamous cell carcinoma (SCC of the uterine cervix, which occurs in postmenopausal women. Presentation of Case. Herein, we describe a case of a 63-year-old woman who presented with 4-month history of postmenopausal vaginal bleeding. 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.

    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.

    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.

    Optical histopathology is fast emerging as a potential tool in cancer diagnosis. Fresh tissues in saline are ideal samples for optical histopathology. However, evaluation of suitability of ex vivo handled tissues is necessitated because of severe constraints in sample procurement, handling, and other associated problems with fresh tissues. Among these methods, formalin-fixed samples are shown to be suitable for optical histopathology. However, it is necessary to further evaluate this method from the point of view discriminating tissues with minute biochemical variations. A pilot Raman and Fourier transform infrared (FTIR) microspectroscopic studies of formalin-fixed tissues normal, malignant, and after-2-fractions of radiotherapy from the same malignant cervix subjects were carried out, with an aim to explore the feasibility of discriminating these tissues, especially the tissues after-2-fractions of radiotherapy from other two groups. Raman and FTIR spectra exhibit large differences for normal and malignant tissues and subtle differences are seen between malignant and after-2-fractions of radiotherapy tissues. Spectral data were analyzed by principal component analysis (PCA) and it provided good discrimination of normal and malignant tissues. PCA of data of three tissues, normal, malignant, and 2-fractions after radiotherapy, gave two clusters corresponding to normal and malignant + after-2-fractions of radiotherapy tissues. A second step of PCA was required to achieve discrimination between malignant and after-2-fractions of radiotherapy tissues. Hence, this study not only further supports the use of formalin-fixed tissues in optical histopathology, especially from Raman spectroscopy point of view, it also indicates feasibility of discriminating tissues with minute biochemical differences such as malignant and after-2-fractions of radiotherapy. 2006 Wiley Periodicals, Inc.

    Induction of labor for medical indications has become a routine practice. To date, the Bishop score remains as the standard method to predict the duration of induced labor. Elastography is an objective method of assessing the relative consistency of tissues. Therefore, we sought to assess strain elastography of cervix to predict delay from induction to delivery in pregnant women with a low Bishop score. Ultrasound elastography was immediately performed before induction of labor for medical indications among patients with a singleton pregnancy at>36 weeks of gestation and a Bishop scorecolor map from blue (hardest tissue) to red (softest tissue) was produced. The cervical elastography was considered as positive if at least one part of its anterior wall was red. We assessed the predictive value of elastography on vaginal delivery within 24 hours. Patients delivering by cesarean section were excluded from this study. Elastography was initially performed in 48 patients. Twelve patients delivering by cesarean section after induction of labor were excluded, leading to 36 patients evaluated in this study. Among these 36 patients with elastography performed before induction of labor, 20 had a second elastography before the second dose of misoprostol. Sensibility, specificity, positive predictive value (PPV) and negative predictive value (NPV) of elastography performed before induction of labor on vaginal delivery within 24 hours were 40%, 27.3%, 55.6%, and 16.7%, respectively. Sensibility, specificity, PPV and NPV of elastography performed before the second dose of misoprostol were 64.3%, 16.7%, 64.3% and 16.7%, respectively. Among the 8 patients with red color occurring on the second cervical color map, sensibility, specificity, PPV and NPV were 83.3%, 0%, 62.5%, and 0%. Qualitative cervical elastography is a poor predictor for delay from induction to delivery in pregnant women with a low Bishop score. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Full Text Available Objective: To observe the effect of Angeng Formula on climacteric syndrome in rats. Methods: The ovaries of female SD rats were removed for the establishment of menopausal syndrome rat models. After drug delivery for 30 d, serum sex hormone levels and indexes of uterus, adrenal gland and pituitary were detected. Meanwhile, the effects of drugs on the histopathology of uterus, adrenal gland and pituitary in rats were observed. Results: Angeng prescription could increase the level of estradiol (E2 in castrated rat (P<0.01 and had a tendency to increase the level of progestin (P, lower the level of luteinizing hormone (LH and follicle-stimulating hormone (FSH as well as increase the indexes of the uterus and adrenal gland. Moreover, Angeng prescription could improve the pathologic condition of the uterus, adrenal gland and pituitary in castrated rats. Conclusion: Angeng prescription has a therapeutic effect on climacteric syndrome, the mechanism of which might be related with the function of regulating sex hormone.

    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.

    We report a case of primary malignant melanoma of cervix which is a rare malignancy with only around 60 cases being reported. This patient presented with bleeding per vaginum. A large exophytic growth from cervix with black discolouration was seen. International Federation of Gynaecology and Obsterics (FIGO) staging was stage IIa. Histoimmunocytology confirmed the diagnosis of malignant melanoma of cervix. S-100 and HMB-45 are reliable markers for cervical melanomas. We attempted Wertheim's hysterectomy; but, due to extensive disease, paravescical and pararectal fossae could not be dissected and we had to perform type I hysterectomy. The patient was started on adjuvant chemotherapy with dacarbazine. Despite counselling, she refused a complete course of chemotherapy and died after 6 months. Radical surgery, chemotherapy and immunotherapy are the therapeutic modalities used. In bulky disease, neoadjuvant chemotherapy should be considered to reduce the tumour bulk and facilitate required surgery. Prognosis is poor and unpredictable.

    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.

    The mechanism of synchronizing uterine contractions is not fully understood. We present a case of twin pregnancy in a uterus didelphys and objectively analyze the synchrony of bilateral uterine contractions. A 32-year-old woman, with a history of vaginal septal resection during her previous vaginal delivery, became pregnant with twins in a uterus didelphys in which each uterine horn had one fetus. At 37 weeks and 6 days, the first baby was delivered vaginally. The second baby was delivered by cesarean section due to recurrent late decelerations. Operative findings confirmed the didelphys uterus. We retrospectively reviewed the timing of contractions of both uteruses. The timing was determined by visual analysis as synchronous if both uteruses contracted within 5 s. Otherwise, contractions were considered solitary. Both uterine horns contracted independently in 90% of the incidence throughout labor and delivery.

    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.

    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. Practitioners must validate the

    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

    Full Text Available Cervix is an important part of the reproductive tract; in non-pregnant animals it remains closed during anestrus and diestrus and is open only during estrus. In pathological conditions like pyometra, the cervix may be open or closed but the control mechanism is not clearly known. Prostaglandin E2 (PGE2 is considered to be involved in changes of extracellular matrix via coupling to prostaglandin E receptor subtype 4 (EP4. This study investigated the expression of EP4 in the cervices of bitches during different stages of estrous cycle and those with pyometra. After ovariohysterectomy, cervices were collected from anestrus (n=6, estrus (n=12 and diestrus (n=6, open- (n=10 and closed-cervix pyometra (n=10 bitches. Cervical EP4 expression was observed at all the layers and the stages but the differences in EP4 expression either among bitches in different stages of the estrous cycle and between open- and closed-cervix pyometra were limited to only surface epithelium (SE. In cyclic bitches during estrus and in open-cervix pyometra bitches, significantly higher (P<0.05 EP4 expression was found in SE of uterine part than vaginal part. In SE of the uterine part, the expression was higher in the bitches during estrus than in anestrus and diestrus, and in the bitches affected by open-cervix than those with closed-cervix pyometra. The results suggest that regulation of cervical dilation appeared in the uterine part of the cervix. Moreover, EP4 may be involved in stimulating dilation of the cervix in both estrus and open-cervix pyometra bitches.

    A unicornuate uterus with a rudimentary horn is an anomaly caused by defective fusion of the Müllerian duct, estimated to occur in one in 76,000 pregnancies. Life threateningly heavy bleeding is a highly expected clinical consequence of such pregnancies. According to the known literature, only two living twins and few living singleton pregnancies have been reported up to now. Here we report on an incidentally diagnosed unicornuate uterus with a communicating rudimentary horn, found during a cesarean section of a gravida 3, parity 2 (G3 P2) patient. This case is rather unique since the patient has had three full term pregnancies and three cesarean sections without significant fetal compromise. This delivery and the existing literature showed us that extensive uterine correction surgeries need not be automatically proposed when a unicornuate uterus is diagnosed in the preconception period. Such deliveries indicate that women with this uterine anomaly may have the potential to carry pregnancies to full term.

    Full Text Available Although uterine leiomyomas are the most common neoplasms of the female genital tract, this is not the case when referring to women under the age of 20. Only a few cases of uterus leiomyomas have been reported in this age. Preoperative imaging evaluation is mandatory in adolescent women for the accurate detection, localization, and characterization of uterus leiomyomas. We report a case of a 16-year-old girl admitted to our hospital for pain and abdominal distention. The patient underwent multidetector CT examination of the abdomen and MR examination of the pelvis. Both imaging modalities revealed uterine enlargement and the presence of innumerable variably sized leiomyomas. Histopathologic examination following exploratory laparotomy confirmed the presence of uterus leiomyomas. The patient underwent laparoscopic myomectomy two years after the first operation, following MR examination of the pelvis.

    Uterine arteriovenous malformations (AVMs) are rare entities that have been documented in a wide age range. Several treatment modalities have been highlighted in the literature. Uterine artery embolization appears to be effective therapy for select cases. Embolization provides an alternative to hysterectomy and the potential for future fertility. To our knowledge, only 1 other case report describes an AVM existing within a bicornuate uterus. A 31-year-old, married, Caucasian woman with a history of infertility presented with intermittent uterine hemorrhage resulting in symptomatic anemia. The patient was diagnosed with a uterine AVM existing within the left horn of a bicornuate uterus. The patient underwent uterine artery embolization, with resolution of the vascular mass and resumption of regular menstrual flow. AVM in a bicornuate uterus is rarely reported. Selective uterine artery embolization offers an effective modality of treatment.

    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.

    Tissue strips from the ovary, (uterine tube), and oviduct, and uterus of pregnant and nonpregnant cows were tested for their contractile response to prostaglandin F2 alpha (PGF2 alpha). When 2.1 x 10(-6)M PGF2 alpha was added to the uterine strips, tension of tissues from pregnant cows increased sharply; however, tension in tissues from nonpregnant cows only increased moderately. Similar concentrations failed to elicit any response from oviductal tissues of either group. Unlike the uterus and the oviduct, the ovaries contracted slowly and irregularly. They responded with varying degrees of stimulation; ovaries from pregnant cows with brief and mild stimulation and ovaries from nonpregnant cows with slower and relatively stronger stimulation. Results indicate that the bovine ovary contracts rhythmically and that its sensitivity to PGF2 alpha decreases during pregnancy in contrast to the bovine uterus which becomes increasingly sensitive during pregnancy.

    The surgical treatment of complete genital prolapse must aim the restoration of the vaginal support structures. All 3 levels of the vaginal support system must be recreated. Ablation of the uterus is not useful for pelvic floor support. Sparing of the uterus offers the advantage of a reduced surgical trauma, and better pelvic floor restoration. We present the case of a 60-year old woman with complete genital prolapse where the uterus was spared, and sacrospinous fixation, anterior mesh repair,perineal body repair and suburethral sling insertion were performed. The results were very good, by means of pelvic floor statics and physiology of micturition. genital prolapse must be cured by reconstruction of the vaginal support system, not by hysterectomy.

    Torsion of the gravid human uterus is rarely encountered. Reported cases include uterine leiomyomata, ovarian tumors, uterine anomalies and fetal malpresentation as contributing factors. No case has been reported before in association with maternal trauma. A 20-year-old woman, gravida 2, para 1, presented to the emergency room at 38 1/7 weeks' gestation after being involved in an automobile collision. Two hours after admission, she experienced a severe, prolonged fetal heart rate deceleration, which was unresponsive to conservative measures. An emergency cesarean section was performed. Following delivery of the fetus, it was noted that the uterus had levorotated 180 degrees, and posterior hysterotomy was performed. Placental inspection disclosed a 30% abruption. The mother recovered uneventfully, but the infant suffered acute and long-term morbidity. Uterine torsion should be considered in cases of blunt abdominal trauma to the gravid uterus.

    Developmental anomalies of the uterus and the vagina are associated with infertility and miscarriage and are most commonly detected in the postpubertal age-group. These conditions may also present in younger patients as a mass or pain owing to obstruction of the uterus or the vagina. Associated urinary tract anomalies are common, as well. Accurate diagnosis and thorough description of these anomalies is essential for appropriate management; however, evaluation may be difficult in an immature reproductive tract. Magnetic resonance imaging technique pertinent to imaging of the pediatric female reproductive tract is presented and illustrated along with the findings associated with various anomalies.

    To develop a VX-II carcinoma model in the rabbit uterus and to describe the MR imaging findings of an experimentally induced VX-II uterine carcinoma along with the histopathologic findings. 13 New Zealand rabbits were included in this study. Two pieces of tissue suspension (1 mm{sup 3} x 2) of VX-II carcinoma were loaded in an 18 gauge disposable needle and the tissue embedded in the wall of each horn of the rabbits' uterus. We obtained the MR images at 2 weeks in group A (n = 5), or at 2 and 4 weeks in group B (n = 8). T2-weighted images were obtained using an extremity coil. On MR imaging, we measured the signal intensity of the tumor and the uterine wall. We also measured the size and shape of the tumor and we compared this with the histopathologic results. On MR images obtained 2 weeks after inoculation, all the rabbit uteruses (group A and B, n = 13) show a thick tubular wall, and the uteruses demonstrated a high signal intensity on T2-weighted images. The thickened uterine walls were measured as 3-10 mm (mean: 6.5 mm). Peritoneal nodules were observed in 3/13 rabbits (23%), the nodules measured 1.5-1.8 x 3.0 cm; uterine masses were observed in 3/13 rabbits (23%), and they measured 0.6-1.5 x 1.3-1.5 cm. On MR images obtained 4 weeks after the inoculations (group B, n = 8), rabbit uteruses that had VX-II carcinoma show thick tubular wall in all cases (n = 8, 100%) and round uterine masses (n = 6, 75%). The thickened uterine walls measured 5-14 mm (mean 7.6 mm) and uterine masses measured 1.3-3.0*1.5-6.0 cm. All the rabbit uteruses having VX-II carcinoma showed high signal-to-noise ratios along the thickened uterine walls or masses on T2WI. On the histopathologic exam after sacrificing the rabbit, a few viable tumor cells were found because of necrosis in the inner portion of the uterine tumors, and abundant viable tumor cells were found at the periphery of the uterine tumors. We can develop an animal model with uterine tumor in rabbit uterus using VX

    Müllerian malformations represent a wide spectrum of anomaly of the female reproductive tract, usually detected at birth or at puberty. The presence of uterus didelphys and obstructed hemivagina, associated with ipsilateral renal agenesis, is known as Herlyn-Werner-Wunderlich syndrome, a rare congenital anomaly. Two cases of uterus didelphic and hematometra caused by vaginal septum are reported; the girls had a delayed diagnosis due to absence of a specific clinical feature. Clinicians must be aware of the existence of these malformations. An adequate radiological study is mandatory to assess the anatomic conformation, and to optimize the therapeutic procedures.

    1989-01-01

    Tissue specimens from uterine cervix and corpus of non-pregnant and pregnant women were incubated in vitro in the presence of 3H-norepinephrine. The uptake in the cervix exceeded those of the lower and upper segments of the corpus, and this difference was most pronounced at term pregnancy. The neuronal uptake in the cervix constituted approximately 80% of the total uptake and was higher than in isthmus and fundus (50 and 20%, respectively). The results favour the notion that cervical nerves remain functionally intact throughout pregnancy and support previous histochemical studies demonstrating a segmental difference in uterine innervation and a partial denervation of the myometrium at term.

    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.

  15. Biatrial Cardiac Metastases in a Patient with Uterine Cervix Malignant Melanoma

    2015-01-01

    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.

    To assess the effects of mechanical dilatation of the cervix during cesarean section on postoperative morbidity. A total of 447 women with elective cesarean section were included in the Dondi trial (Dilatation or no dilatation of the cervix during cesarean section). The primary outcome measure of this randomized controlled trial was postpartum hemorrhage (PPH) within 6 weeks. Infectious morbidity (puerperal fever, endometritis, wound infection, and urinary tract infection), blood loss (need for blood transfusion or change in hemoglobin levels), and operating time were also evaluated. The rate of PPH within 6 weeks was not different between the two groups [dilatation group: 5 (2.4 %), no dilatation group: 3 (1.2 %), p = 0.479]. Infectious morbidity, blood loss, and operating time were not diverse as well. The only significant difference between the two groups was the rate of retained products of conception with fewer cases after cervical dilatation (0 versus 6.2 %, p Dilatation of the cervix during cesarean section compared with no dilatation of the cervix did not influence the risk of postpartum hemorrhage. However, there were fewer cases with retained products of conception after dilatation.

    Our aim was to characterize the management and outcome of women admitted to a tertiary high-risk obstetrics unit with a short cervix (≤25 mm), measured on transvaginal ultrasound (TVS), and to determine the latency period from diagnosis to delivery. A retrospective chart review of women admitted to the High Risk Obstetrics Unit at Sunnybrook Health Sciences Centre between 2005-2011 with an ultrasound-identified short cervix was done. A total of 110 women admitted for a short cervix between 2005-2011 (N = 56 singletons; N = 54 twin gestations) met the inclusion criteria. The mean latency to delivery was 62.6 days; mean GA at delivery was 33.9 weeks. Following 7 and 14 days of admission, 5.5% and 11.8% of women had delivered, respectively. Preterm birth occurred in 70% of all women. Cervical length was a significant factor in predicting latency among singletons, whereas the length of stay in hospital for activity restriction was not. Although many women with a short cervix delivered preterm, only a small proportion delivered within 2 weeks of admission. Although it is not clear whether inpatient management improves the pregnancy outcome, these findings have implications for both patient care and health resources.

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

    Radiotherapy is the main treatment modality for uterine cervix cancer. Since the rectum is in the radiation target volume, rectal bleeding is a common late side effect. The study evaluates the risk factors of radiation induced rectal bleeding and discusses its optimal management. A total of 213 patients who completed external beam radiation therapy (EBRT) and intracavitary radiation (ICR) between September 1994 and December 1999 were included in this study. No patient had undergone concurrent chemo-radiotherapy. Ninety patients received radiotherapy according to a modified hyperfractionated schedule. A midline block was placed at a pelvic dose of between 30.6 Gy to 39.6 Gy. The total parametrial dose from the EBRT was 51 to 59 Gy depending on the extent of their disease. The point A dose from the HDR brachytherapy was 28 Gy to 30 Gy (4 Gy x 7, or 5 Gy x 6). The rectal point dose was calculated either by the ICRU 38 guideline, or by anterior rectal wall point seen on radiographs, with barium contrast. Rectal bleeding was scored by the LENT/SOMA criteria. For the management of rectal bleeding, we opted for observation, sucralfate enema or coagulation based on the frequency or amount of bleeding. The median follow-up period was 39 months (12 {approx} 86 months). The incidence of rectal bleeding was 12.7% (27/213); graded as 1 in 9 patients, grade 2 in 16 and grade 3 in 2. The overall moderate and severe rectal complication rate was 8.5%. Most complications (92.6%) developed within 2 years following completion of radiotherapy (median 16 months). No patient progressed to rectal fistula or obstruction during the follow-up period. In the univariate analysis, three factors correlated with a high incidence of bleeding: an icruCRBED greater than 100 Gy (19.7% vs. 4.2%), an EBRT dose to the parametrium over 55 Gy (22.1% vs. 5.1%) and higher stages of III and IV (31.8% vs. 10.5%). In the multivariate analysis, the icruCRBED was the only significant factor ({rho} > 0.0432). The

    Uterine cervical cancer is the second most common cancer among women worldwide. Colposcopy is a diagnostic method used to detect cancer precursors and cancer of the uterine cervix, whereby a physician (colposcopist) visually inspects the metaplastic epithelium on the cervix for certain distinctly abnormal morphologic features. A contrast agent, a 3-5% acetic acid solution, is used, causing abnormal and metaplastic epithelia to turn white. The colposcopist considers diagnostic features such as the acetowhite, blood vessel structure, and lesion margin to derive a clinical diagnosis. STI Medical Systems is developing a Computer-Aided-Diagnosis (CAD) system for colposcopy -- ColpoCAD, a complex image analysis system that at its core assesses the same visual features as used by colposcopists. The acetowhite feature has been identified as one of the most important individual predictors of lesion severity. Here, we present the details and preliminary results of a multi-level acetowhite region detection algorithm for RGB color images of the cervix, including the detection of the anatomic features: cervix, os and columnar region, which are used for the acetowhite region detection. The RGB images are assumed to be glare free, either obtained by cross-polarized image acquisition or glare removal pre-processing. The basic approach of the algorithm is to extract a feature image from the RGB image that provides a good acetowhite to cervix background ratio, to segment the feature image using novel pixel grouping and multi-stage region-growing algorithms that provide region segmentations with different levels of detail, to extract the acetowhite regions from the region segmentations using a novel region selection algorithm, and then finally to extract the multi-levels from the acetowhite regions using multiple thresholds. The performance of the algorithm is demonstrated using human subject data.

    Premature rupture of membranes (PROM) occurs in 8% of term deliveries. In this situation labour induction with prostaglandins, compared with expectant management, results in a reduced risk of chorioamnionitis, neonatal antibiotic therapy, neonatal intensive care (NICU) admission, and increased maternal satisfaction. The use of prostaglandin is associated with an increased rate of diarrhoea and use of analgesia/anaesthesia. Compared with oxytocin, prostaglandin induction results in a lower rate of epidural use and internal fetal heart rate monitoring but a greater risk of chorioamnionitis, nausea, vomiting, more vaginal examinations, neonatal antibiotic therapy, NICU admission and neonatal infection. Women should be informed of the risks and benefits of each method of induction.Misoprostol is gaining increasing interest as an alternative induction agent. It appears to be an effective method of labour induction with term PROM. Further research is needed to identify the preferred dosage, route and interval of administration, and to assess uncommon maternal and neonatal outcomes. There has been limited research on the use of prostaglandins, including misoprostol, for induction of labour with a favourable cervix and intact membranes. Compared with intravenous oxytocin (with and without amniotomy), labour induction using vaginal prostaglandins in women with a favourable cervix (with and without PROM) results in a higher rate of vaginal delivery within 24 hours and increased maternal satisfaction. In women with a favourable cervix, artificial rupture of membranes followed by oral misoprostol has similar time to vaginal delivery compared with artificial rupture of membranes followed by oxytocin. Further research with prostaglandins, including misoprostol, is needed to evaluate other maternal and neonatal outcomes in women being induced with a favourable cervix. No form of prostaglandin induction in women with PROM or favourable cervix has proven clearly superior to

    The Mediterranean diet rich in fruits, vegetables and olive oil has been related to a lower osteoporosis incidence and accordingly to a reduced fracture risk. These observations might be mediated by the active constituents of extra virgin olive oil, and especially polyphenols. In the context of exploring the features of olive oil active constituents on postmenopausal osteoporosis, an extra virgin olive oil total polyphenolic fraction (TPF) was isolated and its effect on the bone loss attenuation was investigated. Female Lewis rats were ovariectomized and fed a diet enriched with a total phenolic extract of extra virgin olive oil in a concentration of 800 mg/kg diet. Oleocanthal, one compound of the polyphenolic fraction, showed a higher relative estrogen receptor binding affinity to the ERα compared to the ERβ. While the TPF only slightly induced the uterine wet weight (490.7 ± 53.7 vs. 432.7 ± 23, p = 0.058), TPF regulated estrogen response genes in the uterus (progesterone receptor, antigen identified by monoclonal antibody Ki67, complement C3). Comparing the quantified bone parameters, the oral TPF substitution did not attenuate the ovariectomy-induced bone loss. The administration of extra virgin olive oil polyphenols regulated uterine estrogen response marker genes in an E2-agonistic manner. The bone loss induced by estrogen ablation was not mitigated by treatment with the polyphenolic extract.

    Full Text Available Uterine contractions are generated by myometrial smooth muscle cells (SMCs that comprise most of the myometrial layer of the uterine wall. Aberrant uterine motility (i.e., hypo- or hyper-contractility or asynchronous contractions has been implicated in the pathogenesis of infertility due to the failure of implantation, endometriosis and abnormal estrous cycles. The mechanism whereby the non-pregnant uterus initiates spontaneous contractions remains poorly understood. The aim of the present study was to employ linear synchronization measures for analyzing the pattern of EMG signal propagation (direction and speed in smooth muscles of the non-pregnant porcine uterus in vivo using telemetry recording system. It has been revealed that the EMG signal conduction in the uterine wall of the non-pregnant sow does not occur at random but it rather exhibits specific directions and speed. All detectable EMG signals moved along the uterine horn in both cervico-tubal and tubo-cervical directions. The signal migration speed could be divided into the three main types or categories: i. slow basic migration rhythm (SBMR; ii. rapid basic migration rhythm (RBMR; and iii. rapid accessory migration rhythm (RAMR. In conclusion, the EMG signal propagation in smooth muscles of the porcine uterus in vivo can be assessed using a linear synchronization model. Physiological pattern of the uterine contractile activity determined in this study provides a basis for future investigations of normal and pathologicall myogenic function of the uterus.

    Full Text Available Focal dermal hypoplasia (FDH is a rare inherited genodermatosis with an X-linked dominant trait. FDH is associated with skin defects and other abnormalities of bone, nails, hair, limbs, teeth and eyes. We present the case of a 26-year-old female in the 27th pregnancy week and a previous history of miscarriage. After careful physical examination and dermal biopsy, histopathology revealed that the patient was a carrier of FDH. This is the first report in the literature describing that FDH is associated with uterus bicornis and renal ectopia. Our association could be attributable to early embryonic abnormalities related with FDH because both the uterus bicornis and the renal ectopia originate around the 3th–6th week of embryonic development. We are unable to confirm that the miscarriages were caused by inherited FDH or that uterus bicornis was the cause. We conducted a literature review using the following terms: FDH, Goltz syndrome, uterus bicornis, and renal ectopia.

    The lymphatic drainage of the cranial part of the uterus is described. Some of the uterine lymphatic vessels are closely associated with the ovarian arterial supply. It is proposed that the uterine lymphatics form part of the local pathway for the transfer of uterine prostaglandin F2 alpha to the ovary for luteolysis.

    Uterine rupture secondary to placenta percreta has been observed in multiparous patients. These cases are typically associated with a prior history of uterine trauma or infection: hysterotomy, myomectomy, cornual resection, dilatation and curettage, manual removal of the placenta or endometritis. Spontaneous rupture of the primigravid uterus without a history of trauma or infection is an exceedingly rare occurrence. This case represents the second reported in the medical literature and the first to result in a live-born infant. A 23-year-old, African American primigravida at 26 weeks' gestation presented with acute-onset abdominal pain, severe hypotension, tachycardia and fetal heart rate decelerations. Blood product replacement was initiated, and an emergency laparotomy was performed for a presumptive diagnosis of intraabdominal hemorrhage. A significant hemoperitoneum was encountered, with the fetus floating freely in the peritoneal cavity. The uterus had a fundal rupture with a clinically apparent placenta percreta that necessitated performing a total abdominal hysterectomy. The patient recovered uneventfully, and the infant survived without significant morbidity. Spontaneous rupture of the primigravid uterus can occur in the absence of a history of uterine trauma or infection. If a gravid woman presents with hypotension, abdominal pain and fetal distress, the differential diagnosis should include rupture of the uterus, regardless of parity or gynecologic history. Rapid diagnosis, blood product replacement and emergency laparotomy are the key steps in successful management.

    Full Text Available Haloxylon salicornicum (H. salicornicum is a plant that is frequently taken as a tea by Bedouin women in Egypt who are experiencing difficulties during pregnancy, as well as to provide relief from dysmenorrhoea. Despite its medical use, there has been no detailed evaluation of the effect of this plant on uterine tissue. Therefore, the initial aim of this study was to determine whether H. salicornicum affected the contraction of the mouse uterus in vitro. The crude aqueous extract of H. salicornicum was found to inhibit the spontaneous contractions of the uterus, with the effect being rapid in onset and completely reversible upon washout. Subsequent purification of the plant extract resulted in the identification of synephrine and N-methyltyramine, both of which were found to have inhibitory effects on the spontaneous contractions of the uterus. The EC50 for the purified constituent identified as synephrine was 0.82 ± 0.24 μg/mL. The inhibitory activity of crude H. salicornicum, as well as the isolated constituents, could be prevented by pretreatment of the uterus with the β-adrenoceptor antagonist propranolol. In conclusion, the use of H. salicornicum during preterm labour appears to be justified, and its pharmacologic effect is consistent with it acting as a β-adrenoceptor agonist.

    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.

    Women with a septate uterus are at increased risk for subfertility, recurrent miscarriage, and preterm birth. Restoration of the anatomy of the uterus by hysteroscopic septum resection is an established intervention. This treatment has been assessed mainly in retrospective cohort studies, which suggested a positive effect on pregnancy outcomes. The major flaw in these studies is the before/after design, which will always favour the tested intervention. To determine whether hysteroscopic septum resection in women of reproductive age with a septate uterus improves live birth rates and to assess the safety of this procedure. We searched the Cochrane Gynaecology and Fertility Group Specialised Register (inception to May 2016), the Cochrane Central Register of Controlled Trials (CENTRAL CRSO) (inception to May 2016), MEDLINE (1946 to May 2016), Embase (1974 to May 2016), PsycINFO (1806 to May 2016), and CINAHL database (1982 to May 2016). We also searched trial registers for ongoing and registered trials, reference lists, the Cochrane Library, unpublished dissertations and theses, conference abstracts, OpenGrey, LILACS, PubMed, and Google. We planned to include randomised controlled trials that assessed the effect on reproductive outcomes and the safety of hysteroscopic septum resection in women of reproductive age with a septate uterus. If there had been studies to include, two review authors would have independently selected studies, assessed trial risk of bias, and extracted data. They would also have contacted study authors for additional information. As in the 2011 version of this review, we identified no randomised controlled trials for inclusion in this update. Hysteroscopic septum resection in women of reproductive age with a septate uterus is performed worldwide to improve reproductive outcomes. At present, there is no evidence to support the surgical procedure in these women. Randomised controlled trials are urgently needed. Two trials are currently underway.

This study aimed to assess the association between miRNA expression in the cervix during pregnancy with lead and mercury levels. Materials & methods: We obtained cervical swabs from pregnant women (n = 60) and quantified cervical miRNA expression. Women's blood lead, bone lead and toenail mercury levels were analyzed. We performed linear regression to examine the association between metal levels and expression of 74 miRNAs adjusting for covariates. Results: Seventeen miRNAs were negatively associated with toenail mercury levels, and tibial bone lead levels were associated with decreased expression of miR-575 and miR-4286. Conclusion: The findings highlight miRNAs in the human cervix as novel responders to maternal chemical exposure during pregnancy. PMID:26418635

    Ten patients with advanced squamous cell carcinoma of the uterine cervix received induction chemotherapy with cis-platinum, mitomycin-C, vincristine, and bleomycin (BOMP) over a 5 week period, followed by radiotherapy with concomitant weekly cisplatinum. Two patients were FIGO stage I-B barrel-shaped, five were stage II-B, and three were III-B. All patients responded to induction chemotherapy with five complete and five partial responses. At the completion of radiation therapy, nine patients had negative biopsies. One patient never reached a complete response and died of distant metastasis. Another underwent total exenteration for a central recurrence and was found to have microscopic paraaortic lymph node involvement. A third recurred in the parametrium. Two patients with barrel-shaped tumors underwent extrafascial hysterectomies; both had negative specimens and tolerated surgery well. Although follow-up is short, this new approach for advanced carcinoma of the cervix yielded excellent results and was well tolerated.

    Full Text Available We report here on a case of 51-year-old woman with metastatic small cell carcinoma of the breast that came from her cancer of the uterine cervix. She underwent radical hysterectomy with bilateral salpingo-oophorectomy due to small cell carcinoma of the uterine cervix, and adjuvant radiotherapy was administered to the pelvis. Breast metastasis with a palpable mass then occurred 3 months after the primary surgery. Simple mastectomy and adjuvant chemotherapy were performed. She initially showed a good response to the therapy, yet she ultimately died of multiple metastases with a fulminating disease course. This is an extremely rare case, and only 1 similar case has been reported earlier, so we report on this case along with a review of the relevant literature.

    Contractile activity was registered isometrically in isolated strip biopsies from the uterine cervix of nonpregnant, early pregnant and term pregnant women, and the influence of electrofield stimulation (EFS) was studied. In the great majority of women an excitatory effect was observed, but occasionally an inhibitory response occurred. The excitatory effect of EFS was reduced and, in many cases, changed to inhibition during treatment with guanethidine and phenoxybenzamine. These inhibitory effects were not antagonized by treatment with propranolol, indicating that the responses were not mediated by beta-adrenoceptors. Tetrodotoxin reduced or abolished the excitatory effect of EFS. The data suggest that contractile activity of the human cervix is influenced by both adrenergic and nonadrenergic neurons, which remain intact throughout pregnancy. This innervation may be a central part of neuromuscular control systems which undergo important adaptive changes during pregnancy and in connection with parturition.

    Full Text Available A 46-year-old woman presented for a second opinion regarding a 3-4 cm mass of the uterine cervix. A prior biopsy had been interpreted as a malignant melanoma of the cervix, resulting in a radical hysterectomy with bilateral salpingo-oophorectomy. This was to be followed by external beam irradiation and immunother­apy; however, given the rarity of this diagnosis, the patient sought a second opinion at our institution. Further review of the pathological material from the hysterectomy revealed a morphologically benign perivascular epithelioid cell neoplasm rather than a malignant melanoma. Close monitoring of the patient was recommended; she is currently disease-free more than three years after her initial presentation.

    Radical hysterectomy with pelvic lymphadenectomy is the treatment of choice for early-stage cervical cancer. Wertheim's original technique has been often modified, mainly in the extent of parametrectomy. Okabayashi's technique is considered as the most radical variant regarding removal of the ventral parametrium and paracolpal tissues. Surgical outcome concerning recurrence and survival is good, but morbidity is high due to autonomic nerve damage. While the autonomic network has been studied extensively, the lymphatic system is less understood. This study describes the lymphatic drainage pathways of the cervix uteri and specifically the presence of lymphatics in the vesico-uterine ligament (VUL). A developmental series of 10 human female fetal pelves was studied. Paraffin embedded blocks were sliced in transverse sections of 8 or 10 μm. Analysis was performed by staining with antibodies against LYVE-1 (lymphatic endothelium), S100 (Schwann cells), alpha-Smooth Muscle Actin (smooth muscle cells) and CD68 (macrophages). The results were three-dimensionally represented. Two major pathways drained the cervix uteri: a supra-ureteral pathway, running in the cardinal ligament superior to the ureter, and a dorsal pathway, running in the utero-sacral ligament towards the rectal pillars. No lymph vessels draining the cervix uteri were detected in the VUL. In the paracolpal parametrium lymph vessels draining the upper vagina fused with those from the bladder. The VUL does not contain lymphatics from the cervix uteri. Hence, the favorable survival outcomes of the Okabayashi technique cannot be explained by radical removal of lymphatic pathways in the ventrocaudal parametrium. © 2013.

    Gartner duct cysts are relatively common congenital cysts in the anterolateral wall of the vagina. Most are small (less than 2 cm) and asymptomatic, but larger cysts may cause problems. We report a rare case of a giant Gartner duct cyst (7 cm) originating from the right lateral portion of the uterine cervix and adjacent myometrium. It appeared as an exophytic multiseptated cystic mass containing different density fluids on CT

    Full Text Available Introduction. Benign, especially polypoid, lesions of the cervix are common in everyday work. Rare tumors of this region are vascular ones, particularly capillary and/or cavernous hemangiomas. Cervical hemangiomas are especially rare, usually asymptomatic and only one third of the cases is clinically manifested as vaginal bleeding, polyps, etc. Case report. We reported a 54-year-old postmenopausal female patient who had undergone conization due to high-grade squamous intra-epithelial lesion (H-SIL. Microscopic analysis of slices confirmed the existence of dysplastic changes in the endocervical epithelium and in small part in the epithelium of the gland of H-SIL type. In 2 of 15 slices, within the walls of the cervix, dilated, amplified and abnormal blood vessels lined with endothelium were observed, vaguely limited by the surrounding connective tissue of lamina propria and smooth muscle wall of the cervix. According to the pathological characteristics, the change corresponded to the hemangioma. Both changes were completely removed. Conclusion. In comparison with the available literature data, the presented case is the first to describe the association of hemangioma and dysplastic changes in the endocervical epithelium. Hemangioma was incidentally discovered in the histological sections of the material after the conization in a postmenopausal women.

    Full Text Available We investigated the in vitro effect of the essential oil of Croton nepetifolius Baill., Euphorbiaceae (EOCN, on spontaneous or induced contractions of circular and longitudinal muscles from the ovine cervix during the luteal phase of the estrous cycle. The relaxant effect of EOCN was expressed as a percentage of the contraction recorded before the addition of the oil and calculated relative to the preparations exposed only to the vehicle. The IC50 (concentration of oil required to produce a 50% maximal reduction in muscle contraction for relaxation of spontaneous contractions in circular and longitudinal muscles was significantly lower than the IC50 for blockade of K+-induced contraction (27.19 µg mL-1 versus 262.72 µg mL-1 and 40.92 µg mL-1 versus 222.47 µg mL-1, respectively. Interestingly, there was a high degree of selectivity in the action of EOCN on cervix layers concerning the inhibition of acetylcholine-induced contraction in circular (IC50 277.10 µg mL-1 and longitudinal (IC50 52.56 µg mL-1 muscles. In conclusion, EOCN is able to relax ovine cervix during the luteal phase. This work opens the perspective of applying EOCN in ovine embryo transfer.

    The authors examined the interaction of exposure to various numbers of sex partners and evidence of antibodies to herpes simplex virus type 2 (HSV-2) in cervical neoplasia in 181 cases of cervical dysplasia, carcinoma in situ and cancer of the cervix and 130 control patients in Los Angeles County, California hospitals, in 1974-1979. Studies by the authors and other investigators have found that risk of cancer of the cervix was enhanced with numbers of sex partners, frequency and duration of using the vaginal douche, early age at first pregnancy, and antibodies to HSV-2 as measured by radioimmunoassay. In this study, it was found that for women with only one or no sex partner in their history, risk was elevated if evidence of antibodies to HSV-2 were present. The same was true for women with two or more sex partners. The risk associated with two or more sex partners was not higher than that for women with one sex partner among those positive for HSV-2, and among those negative for HSV-2. Thus, although this inquiry needs replication on larger numbers of women, whatever the other microorganisms or carcinogens patients were exposed to with multiple sex partners, there was no apparent effect beyond the fact that HSV-2 raises the risk of cancer of the cervix. This may strengthen credence in the hypothesis that HSV-2 is an etiologic factor in cervical cancer.

    The rate of Cesarean Section for failed induction of labor and maternal and fetal compilations are high when labor is induced in a nulliparas women with an unripe cervix by amniotomy and oxytocin infusion. Prostaglandins (PG) in different forms have been used for ripening the cervix with an aim of reducing these problems. A prospective randomized trial was performed on one hundred primigravid women between 37 and 42 weeks of gestation with singleton pregnancy, cephalic presentation and unfavorable cervix (Modified Bishop Score oxytocin infusion and artificial rupture of membrane (ARM). The Modified Bishop Score (MBS), interval between IOL and onset of labor and the duration of labor after insertion of PGE2 gel was significantly different from those of oxytocin infusion group. But the Apgar Score at 1 & 5 min had shown no statistically significant difference. Any significant difference could also not be detected in the mode of delivery between the two induction group. The proportion of emergency Cesarean Section (CS) was high in the oxytocin infusion group than that of in the prostaglandin group. There was also no significant difference regarding the acceptability of both the induction methods.

    Many women can be saved from carcinoma of cervix by detecting and treating its precancerous stage. Pap smear is cheap and easily available in majority of institutes. The objective of this study is to determine the frequency of abnormal Pap smear and role of Pap smear in detecting precancerous stage of cancer cervix in women. This is retrospective descriptive study was conducted in gynaecology outpatient department of Isra University Hospital, Hyderabad, Sind from Nov 2006 to Oct 2009. All women who presented in OPD with gynaecological complaints were included in the study. Pregnant women were excluded from the study. Smear was collected with an Aryes spatula and relevant information was obtained from the patient's record and recorded on pre-designed Performa. Slides were then sent to pathology department. Data were analysed through SPSS-15 and presented as frequency and percentage. Total 981 women underwent Pap smear screening. Majority (63.3%) of the patients belonged to age group of 31-40 years. One hundred and eighty (18.34%) smears were normal and 792 (80.7%) were abnormal. Among these abnormal smears, 739 (75.33%) smears were inflammatory while 4 (0.40%) women had Ca in situ and 4 (0.40%) had squamous cell carcinoma. CONCLUSION. Pap smear is an important screening tool to detect precancerous stage of carcinoma of cervix. It should be done periodically in all married and high risk women for early detection of a precancerous stage.

    Full Text Available Lymphoepithelioma-like carcinoma occurring in the reproductive organs is a rare variant of squamous cell carcinoma, and this tumor of the uterine cervix accounts for 0.7% of all primary cervical uterine neoplasms. Associations with Epstein-Barr virus (EBV and human papilloma virus (HPV have been demonstrated in some studies. Some investigators suggested that EBV has an important role in the initiation of lymphoepithelioma-like carcinoma in Asian women. Here we report the case of a 45-year-old Japanese woman, gravida 2 and parity 2. She was admitted due to severe atypical genital bleeding caused by uterine cervical cancer. A >60-mm tumor was detected at the uterine cervix, and no distal metastasis or swallowing of lymph nodes was revealed by magnetic resonance imaging and a computed tomography scan. The cervical cancer stage FIGO Ib2 was diagnosed, and a radical hysterectomy was performed for this malignant tumor. The in situ hybridization for EBV was negative. HVP infection was strongly suspected because the squamous cell carcinoma was observed macroscopically in the uterine cervix. The prognosis of uterine lymphoepithelioma-like carcinoma is thought to be better than those of other cervical cancer types, but careful follow-up at fixed intervals is recommended. The patient has been followed up for 4 months since her surgery, and no evidence of recurrence has been detected.

    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.

    Uterovaginal duplication with obstructed hemivagina and ipsilateral renal agenesis is referred to as the Herlyn-Werner-Wunderlich (HWW) syndrome. A 17 year old woman presented with right pelvic pain and dysmenorrhea, present since menarche at 13 and worsening over the past year. Ultrasound examination revealed a right pelvic mass (5×5 cm), double endometrial echoes, and hematocolpos. A right pelvic mass, agenesis of the right kidney, double uterus, and blind hemivagina with hematocolpos were detected by magnetic resonance imaging and intravenous pyelography. A right tubo-ovarian abscess with dense adhesions and a double uterus were observed on diagnostic laparoscopy. Adhesiolysis was carried out and purulent material irrigated. After a course of antibiotics, a vaginal septum resection was performed and the pyocolpos drained. She remained symptom free after four months of follow-up. Prompt and accurate diagnosis and treatment of this syndrome can significantly improve the lives of sufferers and prevent future complications.

    Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA), or Herlyn-Werner-Wunderlich syndrome, is a rare Mullerian duct anomaly with uterus didelphys, unilateral obstructed hemivagina, and ipsilateral renal agenesis. Patients with this anomaly usually present after menarche with pelvic pain and/or a mass and rarely, in later years, with primary infertility. Strong suspicion and knowledge of this anomaly are essential for a precise diagnosis. A 14-year-old female presented with acute retention of urine and was diagnosed as a case of OHVIRA syndrome with uterus didelphys. Acute retention of urine as the initial clinical presentation has been rarely reported in this syndrome. She was treated with hemivaginal septal resection. OHVIRA syndrome should be considered among the differential diagnoses in young females with renal anomalies presenting with pelvic mass, symptoms of acute abdomen, and acute urinary retention.

    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.

    Women with Müllerian anomalies are at increased risk of preterm labor. The analysis of parameters derived by the electrohysterogram such as its conduction velocity are promising for preterm delivery prediction. However, an electrohysterogram has never been measured in Müllerian anomalies. A multiparous woman with a unicornuate uterus presented at 28 weeks of gestation with preterm contractions. Three electrohysterogram recordings were performed between 28 and 30 weeks of gestation, 4 weeks before delivery. The conduction velocity values were in line with previous literature and differed significantly (p uterine contractions, in the case of a unicornuate uterus as well as one that is normally developed. © 2013 The Authors Acta Obstetricia et Gynecologica Scandinavica © 2013 Nordic Federation of Societies of Obstetrics and Gynecology.

    Full Text Available Abstract Background VEGF-regulated genes in the cervices of pregnant and non-pregnant rodents (rats and mice were delineated by DNA microarray and Real Time PCR, after locally altering levels of or action of VEGF using VEGF agents, namely siRNA, VEGF receptor antagonist and mouse VEGF recombinant protein. Methods Tissues were analyzed by genome-wide DNA microarray analysis, Real-time and gel-based PCR, and SEM, to decipher VEGF function during cervical remodeling. Data were analyzed by EASE score (microarray and ANOVA (Real Time PCR followed by Scheffe's F-test for multiple comparisons. Results Of the 30,000 genes analyzed, about 4,200 genes were altered in expression by VEGF, i.e., expression of about 2,400 and 1,700 genes were down- and up-regulated, respectively. Based on EASE score, i.e., grouping of genes according to their biological process, cell component and molecular functions, a number of vascular- and non-vascular-related processes were found to be regulated by VEGF in the cervix, including immune response (including inflammatory, cell proliferation, protein kinase activity, and cell adhesion molecule activity. Of interest, mRNA levels of a select group of genes, known to or with potential to influence cervical remodeling were altered. For example, real time PCR analysis showed that levels of VCAM-1, a key molecule in leukocyte recruitment, endothelial adhesion, and subsequent trans-endothelial migration, were elevated about 10 folds by VEGF. Further, VEGF agents also altered mRNA levels of decorin, which is involved in cervical collagen fibrillogenesis, and expression of eNO, PLC and PKC mRNA, critical downstream mediators of VEGF. Of note, we show that VEGF may regulate cervical epithelial proliferation, as revealed by SEM. Conclusion These data are important in that they shed new insights in VEGF's possible roles and mechanisms in cervical events near-term, including cervical remodeling.

    The microbial population represents a group of heterogeneous germs comprising several different species which live and act together in the same place. The communities of micro-organisms, as independent population groups, are better adapted for growing than a unique species. The microbial flora of the puerperal uterus differs from case to case, being represented both as bacteria admitted as pathogenic and particular tropism for the uterine morphological structures and opportunist bacteria whic...

    Myoma is one of the most common benign tumors of uterus and one of the most common causes of vaginal bleeding in women. The purpose of the present study is to evaluate the effect of dopamine receptor agonist cabergoline on the size of myoma and the amount of bleeding in the women with myoma of the uterus. The study was performed as a single blind randomized clinical trial on the women with symptomatic myoma. The women were randomly assigned in 2 groups. In the case group, 0.5mg cabergoline was prescribed weekly for three months, and in the control group, nothing was prescribed and the women only had close observation for symptoms. The reduction in symptoms including pelvic pain and duration and amount of uterine bleeding, and the size of myoma, were compared between the 2 groups. 51 women finished the study (26 women in the case group and 25 women in the control group). There was no significant difference between the 2 groups according to age, gravidity, parity, history of abortion, having living children, pretreatment hemoglobin, pain and amount of uterine bleeding, uterine size, and the size of myoma. After treatment, hemoglobin levels had dropped in the control group but not in the case group (p=0.004). On the other hand, pain had also decreased significantly in the case group in comparison with the control group (p=0.001). Also, the amount of menstrual bleeding (p=0.004), uterine size (p=0.001) and the size of the largest myoma (p=0.013) showed significant reduction in the case group. Cabergoline can decrease the amount of bleeding and pain in the cases of myomatous uterus and can be used for the symptomatic women who want to preserve uterus for a certain period of time.

    2009-05-01

    Arteriovenous malformations (AVMs) of the uterus are rare but potentially life-threatening lesions. The typical presentation includes intermittent, heavy and profuse vaginal bleeding, often refractory to medical therapy. We present the case of a 25-year-old woman presenting 18 months after a 22-week pregnancy loss complicated by a postpartum curettage for retained placenta. The patient's initial symptoms included irregular and extremely heavy vaginal bleeding. Several transfusions of packed red blood cells were required because of severe anemia. On transfer to our institution, evaluation with ultrasound and hysteroscopy revealed a large AVM in the fundus of the uterus, apparently fed by both the right and left uterine arteries. After 2 embolization procedures of the uterine arteries, the patient experienced a recurrence of her symptoms, requiring definitive treatment with a hysterectomy. AVMs of the uterus are a rare cause of vaginal bleeding. AVMs should be considered in the differential diagnosis for the patient with bleeding refractory to medical management and a history of prior uterine surgery. Although unsuccessful in our case, uterine artery embolization remains a viable treatment option, particularly in patients wishing to retain their reproductive capacity.

    Full Text Available Neuroendocrine carcinoma (NEC, also called small cell carcinoma or large cell carcinoma, is a rare and aggressive tumor that develops mainly in the lung and intestine. More rarely, NEC develops in gynecologic organs, with poor prognoses. We experienced a case of NEC in the broad ligament of the uterus. The patient was a 74-year-old woman with symptoms of abdominal distension and constipation. Ultrasound sonography detected an abdominal tumor larger than 10 cm. She was then admitted to our hospital. She underwent surgery under the diagnosis of ovarian cancer, but the bilateral ovaries and uterus were normal in appearance, and a tumor was developing instead from the broad ligament of the uterus. The patient then received a hysterectomy, salpingo- oophorectomies, and lymphadenectomy, and the peritoneal membrane was stripped around the pelvic space. Despite our suggestion, she never accepted the adjuvant treatment. She discontinued her periodic follow-up with us and was followed in another hospital. Generally, the prognosis of NEC is poor, and there is no established treatment for a tumor in a gynecologic lesion. However, we anticipate that the accumulation of experience treating such cases will eventually lead to a standard treatment for NEC.

    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.

    To evaluate the imaging findings of uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis. From March 2003 to December 2008, five patients with uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis were evaluated as part of this study. We retrospectively reviewed the CT, ultrasound, and MRI findings as well as the medical records of each patient. The patients initially underwent an imaging study for abdominal pain (n=3), recurrent vaginal bleeding (n=1), and prenatal evaluation (n=1). Of the five patients that underwent US, four had hematocolpos and two of them had hematometra. Moreover, three patients underwent a CT examination. The MR examination of four patients revealed hematocolpos (n=3), hematometra (n=1), and a tubular structure resembling an ectopic ureter (n=2). The gynecologic examination of a patient without hematocolpos revealed a pinpoint hole in the vaginal septum. Two of four patients with hematocolpos underwent a vaginal septectomy, which resulted in an improvement of the symptoms. The most common finding of patients with uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis is vaginal fluid collection. Hematometra is not a consistent finding and can be transient according to the menstrual cycle. MR is the most useful imaging modality for the diagnosis of an ectopic ureter.

    Many papers have reported that twin pregnancies with one twin demise in the uterus can cause complications in the surviving twin. We retrospectively reviewed charts from 1988 to 1997 at our hospital and found 17 of 302 twin deliveries with one twin intrauterine fetal death. The incidence of intrauterine death of a single twin was 5.7%. Six of the surviving twin (35.3%) had renal function impairment. One died due to acute renal failure. The other five patients recovered normal serum creatinine level. Five patients (29.4%) had abnormal brain imaging findings. One had multicystic encephalomalacia and microcephaly. Three of the five patients were complicated with cerebral palsy. After dividing the patients into complicated (n = 8, 47.1%) and non-complicated (n = 9, 52.9%) groups, we found that the patients with complication had lower Apgar score at 5 minutes and those with monochorionic diamniotic placenta had higher incidences of complication (62.5% vs 12.5%). We conclude that twin pregnancies with one fetal demise in the uterus do result in a higher incidence of complication in the surviving twin, especially if placentation type is monochorionic diamniotic. In managing the surviving twin of the monozygous twin pregnancies with one fetal demise in the uterus, we must be careful to monitor these patients. If complication was suspected, we should arrange the brain and kidney ultrasonography and manage these patients appropriately to decrease the complication risk.

    To clarify the current status of uterus transplantation (UT) and the medical, ethical, and social problems surrounding UT. Systematic review. Not applicable. Mainly nonhuman primates and humans. Not applicable. A systematic search of Pubmed with the terms "uterus/uterine transplantation" was performed for English-language articles to review the current status of UT and issues associated with its clinical application, with a focus on nonhuman primate and human studies on UT. The first UT procedure in humans was conducted for a patient with absolute uterine infertility in Saudi Arabia in 2000. The transplanted uterus was removed after 99 days owing to prolapse and necrosis. That attempt led to a greater focus on basic UT experiments in animal models, including nonhuman primates. The subsequent accumulation of basic data has led to performance of UT in humans by groups in Turkey and Sweden. However, there has yet to be a pregnancy or delivery after allo-UT in primates. Moreover, there are many medical, ethical, and social problems that require examination before clinical application. Clinical application of UT has just begun, but more basic data are needed and medical, ethical, and social problems require thorough discussion before clinical application.

    Cryopreservation of cells and even tissue is feasible. New exciting findings arise in the promising field of cryobiology, e.g. the cryopreservation of whole ovaries. Uterus cryopreservation would be advantageous not only for experimental biology, but also for transplantation surgery. The objective of this study was to evaluate various cryopreservation protocols as well as various storage temperatures in cryopreservation of whole swine uteri. The used freezing protocol was slow (0.2 degrees C/min) after arterial perfusion with 1%, 5% or 10% dimethyl sulfoxide (DMSO) solution for 10 min and equilibration in this solution for 30 min. Viability of the organs was tested by histological examination, biochemical parameters and by the capability of rhythmical contractions in a perfusion system. Eighty swine uteri were cryopreserved. All uteri that were frozen with 10% and 5% DMSO were viable after thawing for at least 1 h, whereas only 40% survived with the use of 1% DMSO and 0% with the use of 0.5% DMSO, respectively. There was no difference regarding the survival rates after various cryostorage periods for up to 16 weeks or after cryostorage for 2 weeks in -70 degrees C or -130 degrees C. The cryopreservation of a whole organ such as the swine uterus is a valuable method for the study of cryoprotective agents and freezing protocols. This study demonstrates clearly that the perfusion of the organ with cryoprotectants is the only factor which allows the uterus to contract.

    The ultrastructural features of the vitelline follicles, uterus and vagina of the amphilinid cestode Amphilina foliacea from the body cavity of Acipenser ruthenus of the Volga basin are described. Some new distinguishing characters are revealed, including the presence of a single type of the cellular component in the vitelline follicles with sarcoplasmic processes filling the space around and within vitellocytes. The,uterus of this species is recognized by the presence of the syncytial epithelial lining with underlying secretory perikaria and different kinds of luminal projections. The most distal part of the uterus, situated closely to the uterine pore, is characterized by nuclei occupying the syncytial uterine epithelium. Slightly further proximally, they are located basally and then transformed into sunken perikaria. The vaginal epithelium is characterized by the syncytial structure with underlying epithelial perikaria in its distal region, with intraepithelial location of the nuclei slightly further proximally and the absence of the nuclei in its proximal region (the seminal receptacle). The syncytial cytoplasm of the vagina contains numerous vesicles and possesses microvilli-like surface structures. The morphological aspects of the female reproductive system of A. foliacea are compared with those of other Cestoda and Neodermata.

    To determine whether β2 -adrenoceptor (β2 AR) genotype is associated with shortening of the cervix or with preterm birth (PTB) risk among women with a short cervix in the second trimester. A case-control ancillary study to a multicentre randomised controlled trial. Fourteen participating centres of the Maternal-Fetal Medicine Units Network of the Eunice Kennedy Shriver National Institute of Child Health and Human Development. Four hundred thirty-nine women, including 315 with short cervix and 124 with normal cervical length. Nulliparous women with cervical length genotype was determined at positions encoding for amino acid residues 16 and 27. Genotype distributions were compared between case and control groups. Within the short cervix group, pregnancy outcomes were compared by genotype, with a primary outcome of PTB Genotype data were available at position 16 for 433 women and at position 27 for 437. Using a recessive model testing for association between short cervix and genotype, and adjusted for ethnicity, there was no statistical difference between cases and controls for Arg16 homozygosity (OR 0.7, 95% CI 0.4-1.3) or Gln27 homozygosity (OR 0.9, 95% CI 0.3-2.7). Among cases, Arg16 homozygosity was not associated with protection from PTB or spontaneous PTB. Gln27 homozygosity was not associated with PTB risk, although sample size was limited. β2 AR genotype does not seem to be associated with short cervical length or with PTB following the second-trimester identification of a short cervix. Influences on PTB associated with β2 AR genotype do not appear to involve a short cervix pathway. © 2015 Royal College of Obstetricians and Gynaecologists.

  2. Uterine torsion in a Sprague Dawley rat (Rattus norvegicus

    2011-04-01

    Full Text Available Uterine torsion is a twisting of the uterus or uterine horn perpendicular to its long axis.We report a case of uterine torsion in an adult breeding Sprague Dawley rat. The rat died a month after her last recorded delivery. Post mortem examination of the rat revealed 270° torsion of the right uterine horn. The uterus contained a single foetus. The liver was pale and enlarged. The rest of the viscera appeared normal. Histopathological examination showed acute hepatic necrosis and pulmonary congestion with mild lymphocytic infiltrates peribronchially. The acute hepatic necrosis may have been associated with septicaemia due to compromised blood vessels following the uterine torsion. The presence of a single foetus could have resulted in foeto-maternal disproportion with resultant uterine torsion. Torsion of the uterus can be accompanied by haemostatic and metabolic complications, which could have caused the death of the rat. Although uterine torsion is a rare condition in rats, it should be considered as a potential complication of gestation in animal breeding units.

  3. The Dosimetric Consequences of Intensity Modulated Radiotherapy for Cervix Cancer: The Impact of Organ Motion, Deformation and Tumour Regression

    Science.gov (United States)

    Lim, Karen Siah Huey

    Hypothesis: In intensity modulated radiotherapy (IMRT) for cervix cancer, the dose received by the tumour target and surrounding normal tissues is significantly different to that indicated by a single static plan. Rationale: The optimal use of IMRT in cervix cancer requires a greater attention to clinical target volume (CTV) definition and tumour & normal organ motion to assure maximum tumour control with the fewest side effects. Research Aims: 1) Generate consensus CTV contouring guidelines for cervix cancer; 2) Evaluate intra-pelvic tumour and organ dynamics during radiotherapy; 3) Analyze the dose consequences of intra-pelvic organ dynamics on different radiotherapy strategies. Results: Consensus CTV definitions were generated using experts-in-the-field. Substantial changes in tumour volume and organ motion, resulted in significant reductions in accumulated dose to tumour targets and variability in accumulated dose to surrounding normal tissues. Significance: Formalized CTV definitions for cervix cancer is important in ensuring consistent standards of practice. Complex and unpredictable tumour and organ dynamics mandates daily soft-tissue image guidance if IMRT is used. To maximize the benefits of IMRT for cervix cancer, a strategy of adaptation is necessary.

    2003-04-01

    Full Text Available Abstract Background The CCAAT element binding protein family of transcriptional factors consists of at least six members of the basic leucine zipper DNA binding proteins that bind to the same CCAAT palindromic DNA sequence through homo- or hetero-dimerization with the same family members. C/EBP β has been shown to play an important role in mediating the effects of the LH/hCG in ovarian development. C/EBP β was also found increased in ovarian cancer and correlated to ovarian cancer progression. Design We assessed the C/EBP β expression pattern in the normal and neoplastic conditions of the female genital tract by immunostaining the normal cervix – 10 cases, squamous intraepithelial lesion (SIL-10, invasive squamous carcinomas of cervix – 10 cases, normal endometrial tissue – 10 cases, and invasive endometrial adenocarcinomas carcinomas-10 cases. The staining pattern and intensity were graded from 0 to 2+. Results were statistically analyzed utilizing JMP 4.1. Results C/EPB β expression was detected in the normal proliferative squamous, dysplastic and malignant squamous epithelial cells. There was no statistical correlation between C/EPB β staining in benign squamous, endocervical tissue, SIL, and squamous cancer, as the majority of all stained positively (91%, 79%, 71% and 89%, respectively, p = 0.3448. However, endometrial carcinoma was significantly more likely to stain positively with C/EPB β than benign endometrial glands (92% versus 3% respectively, p Conclusion C/EBP β is more likely to be preferentially expressed in endometrial adenocarcinoma as compared to benign endometrial tissue. There is no difference of C/EPB β expression in squamous neoplasia of the cervix.

    Full Text Available Purpose : To determine the feasibility and safety of outpatient combined intracavitary and interstitial brachytherapy for cervix cancer with sedation and local anesthesia. Material and methods : We included patients diagnosed with non-metastatic cervix cancer and have completed brachytherapy between December 2015 and December 2016. Moderate to deep sedation was achieved using intravenous midazolam, propofol, fentanyl, and oxycodone. Local anesthesia was achieved with 2% lignocaine gel and a paracervical block containing a mixture of 1% ropivacaine, 2% lignocaine, and 1 : 1,000 adrenaline. Ceftriaxone and ondansetron were given prophylactically. Physiologic monitoring was performed throughout and pain scores were recorded using the Numeric Rating Scale. Follow-up was conducted at 8 weeks from the last fraction of brachytherapy. The feasibility and safety endpoints were a post-anesthesia discharge score (PADS of 9 or above, and no grade 3 or above adverse events, respectively. Results : A total of thirty-five brachytherapy insertions were carried out on nine patients. The median age of the patients was 56 years (range, 40-65. Eight patients had American Society of Anesthesiologists’ physical status of I or II, and one had a status of III. The mean duration of the insertion was 39 minutes (standard deviation [SD] = 14, during which no adverse events occurred. There was no significant nausea or vomiting post-sedation. The median pain scores post-insertion and during recovery were 0 (range, 0-6 and 0 (range, 0-7, respectively. At discharge, all patients had pain scores of 0 and maximum PADS of 10. The mean time to discharge was 4.1 hours (SD = 0.95. There were no brachytherapy-related admissions or complications. Conclusions : Outpatient combined intracavitary and interstitial brachytherapy for cervix cancer with sedation and local anesthesia is feasible and safe. This could potentially lead to significant cost savings.

  6. Collagen Fiber Orientation and Dispersion in the Upper Cervix of Non-Pregnant and Pregnant Women.

    Directory of Open Access Journals (Sweden)

    Wang Yao

    Full Text Available The structural integrity of the cervix in pregnancy is necessary for carrying a pregnancy until term, and the organization of human cervical tissue collagen likely plays an important role in the tissue's structural function. Collagen fibers in the cervical extracellular matrix exhibit preferential directionality, and this collagen network ultrastructure is hypothesized to reorient and remodel during cervical softening and dilation at time of parturition. Within the cervix, the upper half is substantially loaded during pregnancy and is where the premature funneling starts to happen. To characterize the cervical collagen ultrastructure for the upper half of the human cervix, we imaged whole axial tissue slices from non-pregnant and pregnant women undergoing hysterectomy or cesarean hysterectomy respectively using optical coherence tomography (OCT and implemented a pixel-wise fiber orientation tracking method to measure the distribution of fiber orientation. The collagen fiber orientation maps show that there are two radial zones and the preferential fiber direction is circumferential in a dominant outer radial zone. The OCT data also reveal that there are two anatomic regions with distinct fiber orientation and dispersion properties. These regions are labeled: Region 1-the posterior and anterior quadrants in the outer radial zone and Region 2-the left and right quadrants in the outer radial zone and all quadrants in the inner radial zone. When comparing samples from nulliparous vs multiparous women, no differences in these fiber properties were noted. Pregnant tissue samples exhibit an overall higher fiber dispersion and more heterogeneous fiber properties within the sample than non-pregnant tissue. Collectively, these OCT data suggest that collagen fiber dispersion and directionality may play a role in cervical remodeling during pregnancy, where distinct remodeling properties exist according to anatomical quadrant.

    To evaluate the feasibility and efficiency of direct visual inspection after Lugol iodine painting in detecting cervical premalignant and malignant lesions. This study included 1,012 women recruited from gynecology outpatient clinic screened for premalignant or malignant lesions of the cervix. All women underwent cervical smear test, direct visual inspection of the cervix after painting with acetic acid (DVI-A) and after painting with Lugol iodine (DVI-LI). Abnormal test results were referred for colposcopy and biopsy. Cervical smears were abnormal in 24 women (2.4%). Direct visual inspection of the cervix after painting with acetic acid test was abnormal in 92 women (9.1%). Direct visual inspection after Lugol iodine painting test was abnormal in 93 women (9.2%). There were 106 women (10.5%) referred for colposcopy, with 88 women (8.8%) having biopsies taken. Biopsies showed premalignant and malignant lesions in 44 cases only. There were 35 low-grade squamous intraepithelial lesion, 5 high-grade squamous intraepithelial lesion, and 4 cervical cancers. Test efficiency parameters particularly sensitivity, specificity, and positive and negative predictive values of DVI-LI were 97.7%, 94.8%, 46.2%, and 99.9%, respectively; those of cytology were 22.7%, 97.6%, 41.7%, and 96.6%, respectively, and those of DVI-A were 90.9%, 94.6%, 43.5%, and 99.6%, respectively. Direct visual inspection after Lugol iodine painting is feasible and easy to perform with superior sensitivity to cervical cytology and DVI-A in detecting cervical premalignant and malignant lesions. Direct visual inspection after Lugol iodine painting can be used as an efficient primary screening tool with a satisfactory low biopsy rate in low resources settings.

  8. Inhibition of oxytocin-induced but not angiotensin-induced rat uterine contractions following exposure to sodium sulfide

    Low concentrations of sodium sulfide reversibly attenuate the contractile response of the isolate rat uterus to oxytocin without affecting angiotensin II responsiveness. These findings suggest that functionally important disulfide bonds in the rat uterine oxytocin receptor, but not the angiotensin receptor, are sensitive to hydrosulfide ion. Reduction of oxytocin receptors by hydrosulfide ion may be a mechanism by which low level of H{sub 2}S delay parturition in rats.

    The case of a patient diagnosed with uterine cervix cancer is presented as an example of the clinical application of the radiobiological compensation method implemented at Centro Estatal de Cancerologia de Durango. Radiotherapy treatment was initially modified to compensate for the chemotherapy component and, as medical complications arose during treatment delivery resulting in an 18 days gap, new compensation followed. All physical and radiobiological assumptions to calculate the Biologically Effective Dose in the external beam and brachytherapy parts of the treatment are presented. Good local control of the tumor was achieved, the theoretical tolerance limits for the organs at risk were not surpassed and the patient manifested no extensive morbidity.

    Primary fallopian tube carcinoma are extremely rare and are most commonly of serous or endometrioid type. Primary squamous cell carcinomas are exceptional with only three cases reported in the English literature. We present the case of a 43-year-old woman operated for cervical carcinoma. Histologic examination, showed a squamous cell carcinoma of cervix with post operative discovery of a concomitant microinvasive squamous carcinoma of fallopian tube developing on high grade dysplasia and in situ carcinoma lesions. Clinico-pathological features of fallopian tube carcinoma, in general, and squamous carcinoma, in particular, will be discussed.

    To investigate the suitable mode of induced termination of pregnancy at second and third trimester for women with scarred uterus. A retrospective study was performed in 90 cases of second and third trimester pregnant women with scarred uterus, who requested termination of pregnancy due to medical indications in Beijing Obstetrics and Gynecology Hospital from September 2002 to June 2009. The indications of termination of pregnancy were fetal anomaly, serious pregnant complication and intrauterine fetal deaths. 72 second trimester pregnant women and 18 third trimester pregnant women were included in this study. The interval time of previous operation to this pregnancy were recorded. And it was parity. (2) The mode of previous operation (inducing the scar of uterus), previous operation time and indication. (3) The mode of induced labor in this pregnancy, the interval time from administration to uterine contraction, delivery or not and the interval time from induction to delivery. (4) Postpartum hemorrhage, the successful rate of induce labor, placental retention ratio and rupture of uterus or not. (1) It had no significant difference between group A and group B in age, gravidity, parity and the interval time of previous operation to this pregnancy (P > 0.05). But there was significant difference between two groups in gestational weeks of induction (16 weeks vs. 25 weeks, P 0.05), but the time from induction to regular uterine contraction and delivery in group B was significant shorter than that of group A (P < 0.01). The rate of delivery with 24 hours in group B was 94%. It was significant higher than that of group A (13%, P < 0.01). (3) The rate of retained placenta in group B (31%, 11/35) was significant higher than group A (10%, 5/52), but the ratio of residual of placenta and membranes in group A was significant higher than that of group B (54% vs. 34%). It was no significant difference in total rate of postpartum complication between two groups. Further analysis

    INTRODUCTION: Preterm cervical shortening and cervical insufficiency may be caused by a constitutional weakness of the cervix. The aim of this study was to assess the cervical collagen concentration in non-pregnant women with a history of cervical insufficiency or of a short cervix in the second...... (63.5 ± 5.1%; mean ± SD) compared with controls (68.2 ± 5.4%; p = 0.0004); area under the ROC curve 0.73 (95% CI 0.62-0.84). A cut-off value at 67.6% collagen resulted in a positive likelihood ratio of 3.2, a sensitivity of 60%, and a specificity of 81%. Also, women with a short cervix in the second...

    The aim was to determine the long-term prognosis in patients with stage IIIb-IVa squamous cell carcinoma of the cervix who were treated with intra-arterial neoadjuvant chemotherapy (NAC), and to analyze factors related to prognostic value. The authors assessed the disease-free survival of 21 patients with FIGO stage IIIb-IVa squamous cell carcinoma of the cervix treated with intra-arterial NAC followed by irradiation therapy. Before chemotherapy, five factors (age, clinical stage, histologic type, parametrial involvement and serum level of SCC) were evaluated for their correlation with disease-free survival. Univariate Cox's proportional hazard model also demonstrated that age was a significant prognostic factor as a continuous variable. Intra-arterial NAC thus appeared to be effective in treating older patients with stage IIIb-IVa squamous cell carcinoma of the cervix.

    A unique case is described of a 21-year-old female with gonorrhea, condylomata acuminata of the vulva and the uterine cervix, a squamous-cell papilloma and precancerous changes in the cervix. In the observed lesion, a very gradual transition was seen from benign areas, displaying marked cytoplasmic vacuolization, to moderately dysplastic areas, with only slight vacuolization. Giant squamous cells with centrally located vesicular or hyperchromatic nuclei were a prominent feature of both the condylomatous and premalignant portions of the lesion. A geographic correlation was observed in the 18 districts of Uganda between the incidence of vulvar and vaginal condylomata acuminata and cervical cancer; the finding may include cervical warts since vulvovaginal changes often extend to the cervix uteri. In addition to the common flat condyloma, the acuminate variant may be a precursor of cervical cancer and progress to malignancy through the stage of a squamous-cell papilloma.

    Cancer of the cervix is exceedingly uncommon in the Malaysian Orang Asli (aborigine), despite the presence of factors associated with an increased risk of developing this malignancy. In only three patients was the diagnosis of carcinoma of the cervix established, out of a total of nearly 18,000 female inpatients, admitted to the Gombak Orang Asli Hospital over a 13-year period. Over this same period, 81 female patients were diagnosed as having cancer. Interviews with female Orang Asli patients show the presence of alleged risk factors for cervical cancer, including early age of first intercourse, multiparity and non-circumcision of husbands. The low incidence of cancer of the cervix in this aborigine community may be due to the strict moral code of the Orang Asli, limiting extramarital sexual activity and associated venereal infection.

    Good knowledge of physiological {sup 18}F-fluorodeoxglucose ({sup 18}F-FDG) uptake in the healthy population is of great importance for the correct interpretation of {sup 18}F-FDG positron emission tomography (PET) images of pathological processes. The purpose of this study was to investigate the physiological {sup 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 {sup 18}F-FDG PET and pelvic magnetic resonance (MR) imaging. Focal {sup 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 {sup 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 {sup 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 {sup 18}F-FDG uptake in the endometrium, with an SUV of 4.6{+-}1.0. No physiological {sup 18}F-FDG uptake was observed in the ovaries or uterus of any postmenopausal women. In women of reproductive age, {sup 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 {sup 18}F-FDG PET images.

    At the present time approximately 1 in 1000 young people aged between 16 and 35 years will have been cured of cancer in childhood and some of the treatment regimens used will have predictable effects on their future fertility prospects. In young women who have been exposed to radiotherapy below the diaphragm, the reproductive problems include the risk of ovarian failure and significantly impaired development of the uterus. The magnitude of the risk is related to the radiation field, total dose and fractionation schedule. Premature labour and low birth weight infants have been reported after flank abdominal radiotherapy. Female long-term survivors treated with total body irradiation and marrow transplantation are also at risk of ovarian follicular depletion and impaired uterine growth and blood flow, and of early pregnancy loss and premature labour if pregnancy is achieved. Despite standard oestrogen replacement, the uterus of these young girls is often reduced to 40% of normal adult size. Uterine volume correlates with the age at which radiation was received. Regrettably, it is likely that radiation damage to the uterine musculature and vasculature adversely affects prospects for pregnancy in these women. It has been demonstrated that, in women treated with total body irradiation, sex steroid replacement in physiological doses significantly increases uterine volume and endometrial thickness, as well as re-establishing uterine blood flow. However, it is not known whether standard regimens of oestrogen replacement therapy are sufficient to facilitate uterine growth in adolescent women treated with total body irradiation in childhood. Even if the uterus is able to respond to exogenous sex steroid stimulation, and appropriate assisted reproductive technologies are available, a successful pregnancy outcome is by no means ensured. The uterine factor remains a concern and women who are survivors of childhood cancer and their carers must recognize that these pregnancies

    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.

    Full Text Available In recent years, due to reduced training opportunities, the major shift in surgical training is towards the use of simulation and animal laboratories. Despite the merits of Virtual Reality Simulators, they are far from representing the real challenges encountered in theatres. We introduce the “Cattle Uterus Model” in the hope that it will be adopted in training courses as a low cost and easy-to-set-up tool. It adds new dimensions to the advanced hysteroscopic surgery training experience by providing tactile sensation and simulating intraoperative difficulties. It complements conventional surgical training, aiming to maximise clinical exposure and minimise patients’ harm.

    Full Text Available An 8-year-old, crossbred domestic queen, weighing 2.9 kg, was examined because of obvious clinical signs, including anorexia, lethargy and vomiting, with small quantities of yellow vaginal mucopurulent discharge. Palpation revealed the presence of an abdominal mass. A diagnosis of pyometra was made by radiology. After undergoing ovario-hysterectomy, the queen made a full recovery. Histopathological examination of the uterus and ovary was made. A sterilization case was included for microscopic comparison. Results showed that endometrium of the cat with pyometra presented atrophy and shedding of superficial epithelium, and there were apparent cystic follicles in ovary.

    Full Text Available Carcinoma of the cervix is the second to fourth most common malignancy in women. It metastasizes most often to the lungs, bones, and liver. Skin involvement originating from cervical cancer is rare, even in the terminal stages of the disease. Cutaneous metastasis of cervical cancer usually presents as cutaneous nodules, papules/plaques, maculopapular rash, and diffuse inflammatory rash. We report a rare case (only the second reported case to the best of our knowledge of a 50-year-old woman with cutaneous metastasis in form of fungating ulcerative growth on mons pubis as presenting feature of carcinoma cervix.

    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.

    To determine MR imaging features and staging accuracy of neuroendocrine carcinomas (NECs) of the uterine cervix with pathological correlations. Twenty-six patients with histologically proven NECs, 60 patients with squamous cell carcinomas (SCCs), and 30 patients with adenocarcinomas of the uterine cervix were included. The clinical data, pathological findings, and MRI findings were reviewed retrospectively. MRI features of cervical NECs, SCCs, and adenocarcinomas were compared, and MRI staging of cervical NECs was compared with the pathological staging. Cervical NECs showed a higher tendency toward a homogeneous signal intensity on T2-weighted imaging and a homogeneous enhancement pattern, as well as a lower ADC value of tumour and a higher incidence of lymphadenopathy, compared with SCCs and adenocarcinomas (P < 0.05). An ADC value cutoff of 0.90 x 10{sup -3} mm{sup 2}/s was robust for differentiation between cervical NECs and other cervical cancers, with a sensitivity of 63.3 % and a specificity of 95 %. In 21 patients who underwent radical hysterectomy and lymphadenectomy, the overall accuracy of tumour staging by MR imaging was 85.7 % with reference to pathology staging. Homogeneous lesion texture and low ADC value are likely suggestive features of cervical NECs and MR imaging is reliable for the staging of cervical NECs. (orig.)

    Full Text Available Background. Sarcomatoid squamous cell carcinoma is a rare and aggressive form of cervical cancer. We report a case of metastatic sarcomatoid squamous cell carcinoma (SSCC of cervix that presented with an anterior chest wall mass. Case. A 43-year-old Hispanic female presented with a two-month history of a central chest wall mass. The patient’s only past medical history was SSCC of the cervix, stage IIB, diagnosed two years priorly. She underwent neoadjuvant chemoradiation therapy (CRT with cisplatin followed by radical hysterectomy. Surgical margins were positive which led to adjuvant CRT with carboplatin and paclitaxel. PET scan 4 months after the postoperative treatment was negative for recurrence and metastatic disease. On current presentation, the CT chest revealed anterior mediastinal destructive soft tissue mass involving sternum, and the biopsy showed SSCC. The patient received palliative radiation therapy to her chest with improvement in pain and ability to swallow. After discussing the prognosis she refused further chemotherapy and decided on hospice care. Conclusion. Despite good response to first-line therapy, SSCC tends to recur early and does not respond to second-line therapy. Radiation therapy seems to be the most effective modality for treatment, but randomized controlled trials of therapy are impractical.

    Full Text Available Abstract Background Adenoid basal carcinoma of the cervix is a rare condition mostly occurring among postmenopausal women. Although it can be confused with adenoid cystic carcinoma of the cervix, adenoid basal carcinoma has several clinicopathologic features that will allow distinction from adenoid cystic carcinoma. Case presentation This is the case of a twenty-year old African-American female who initially presented with a high-grade squamous intraepithelial lesion on Pap smear, with a subsequent cervical LEEP specimen revealing adenoid basal carcinoma. The lesion showed the characteristic histologic features of adenoid basal carcinoma and was positive for the immunohistochemical marker EMA and negative for collagen IV, further defining the tumor while helping to rule out the possibility of adenoid cystic carcinoma. As far as the authors are aware, this is the youngest reported case of adenoid basal carcinoma to date. Conclusion This case shows that adenoid basal carcinoma can deviate markedly from its typical postmenopausal demographics to affect women as young as 20 years of age. In addition, adenoid basal carcinoma has several identifiable features that will differentiate it from adenoid cystic carcinoma including histologic and cellular morphologies, as well as immunohistochemistry. Treatment for most patients involves hysterectomy, LEEP, or a conization procedure which provides a favorable prognosis because of this lesion's low potential for recurrence and metastasis.

    Today around 275000 women a year in the world keep dying from the cancer of uterine cervix due to the difficulty to meet the logistic requirements of an organized screening in the developing world. Polarimetric imaging is a new promising technique with a tremendous potential for applications in biomedical diagnostics: it is sensitive to slight morphological changes in tissues, can provide wide field images for the screening and requires light sources such as a LED for example. This work intends to characterize the polarimetric response of the uterine cervix in its healthy and pathological states. An extensive series of ex-vivo measurements is in progress the Kremlin Bicêtre hospital near Paris using an imaging multispectral Mueller polarimeter in backscattering configuration. The goal of this study is to evaluate the performances of polarimetric imaging technique in terms of sensitivity and specificity for the detection of healthy epithelia (Healthy Squamous epithelium and Malpighian Metaplasia) with respect to the diagnosis provided by pathologists from histology slides as the "gold standard". We show that, at λ=550nm, performances as high as 62% sensitivity and 64% specificity are achieved by optimizing a simple threshold on the scalar retardance values.

    Primary melanomas of the uterine cervix are rare tumors with no more than 60 cases reported in the world literature. Poor prognosis is considered for the neoplasia itself as well as for diagnostic tardiness. There is no standard treatment; however, radical surgery is the treatment cornerstone. Our aim was to present the case of a 34-year-old woman with a primary malignant melanoma in the uterine cervix with affectation of the posterior face of the vagina without metastasis. Total infraelevator pelvic exenteration and adjuvant radiotherapy was performed. The patient was under surveillance for 8 years of followup without evidence of local or distant disease. The majority of case reports found suggests radical hysterectomy as the treatment indicated for these patients. Notwithstanding this, survival is very short when patients are treated in this manner. Based on our results and on those reported in the literature, we propose initial treatment with total pelvic exenteration as optimal management for this neoplasia in its initial form.

    Aims. Worldwide, cervical cancer is the fifth most deadly cancer in women, but screening prevents cancer by detecting precancerous lesions. The purpose of this study is to present the treatment profile for precancerous lesions of the uterine cervix, according to demographic data. Methods. An annual retrospective study was conducted in two public primary health care centres in Greece. The total number of Pap smears and colposcopies performed as well as the management of women with cervical intraepithelial neoplasia was collected and analysed. Results. Demographic characteristics and correlations with levels of Cervical Intraepithelial Neoplasia (CIN) and treatment path are presented. For each case, we noted the patients' age, the marital and educational status, and the professional and insurance type. From a total of 238 diagnostic procedures, 118 (49.5%) showed precancerous lesions, 83.3% of these were high grade while 16.7% were low grade. Conclusions. This study provides an estimate of the extensiveness of precancerous lesions of the uterine cervix. Management of CIN should be accounted for when balancing the benefits and unfavourable effects of this screening. PMID:21637358

    Full Text Available The connection between human papillomavirus (HPV infection and the consequent sequelae which establishes cervical neoplastic transformation and invasive cervical cancer has redefined many aspects of cervical cancer research. However there is still much that we do not know. In particular, the impact of external factors, like seminal fluid in sexually active women, on pathways that regulate cervical inflammation and tumorigenesis, have yet to be fully understood. HPV infection is regarded as the initiating noninflammatory cause of the disease; however emerging evidence points to resident HPV infections as drivers of inflammatory pathways that play important roles in tumorigenesis as well as in the susceptibility to other infections such as human immunodeficiency virus (HIV infection. Moreover there is emerging evidence to support a role for seminal fluid, in particular, the inflammatory bioactive lipids, and prostaglandins which are present in vast quantities in seminal fluid in regulating pathways that can exacerbate inflammation of the cervix, speed up tumorigenesis, and enhance susceptibility to HIV infection. This review will highlight some of our current knowledge of the role of seminal fluid as a potent driver of inflammatory and tumorigenic pathways in the cervix and will provide some evidence to propose a role for seminal plasma prostaglandins in HIV infection and AIDS-related cancer.

    Full Text Available Aim: To detect prognostic role of cervical elastosonography (ES among women with a history of idiopathic recurrent spontaneous miscarriage (IRSM in early pregnancy. Methods: There were 40 women enrolled in the study. Of the 40, 20 were women diagnosed with IRSM in the first trimester and 20 were healthy women who had at least one childbirth experience. All patients underwent ES evaluation of the cervix. Strain ratio values of certain cervical tissue were recorded for all women. Results: The results of elastosonographic measures showed that external part of the upper lip of the cervix was significantly softer than the internal part and lower lip in women with IRSM. However, for women who had not experienced miscarriage, the results were not different. There were no significant differences observed between cervical length and elasticity among either group. Conclusion: Although we found that Region A was softer than Region C and D in women with IRSM, we also found similar results for women who have not experienced miscarriage. Our results support that cervical elasticity may not play a central role in the detection of etiopathogenesis of IRSM. Further studies with larger groups are needed.

    Full Text Available Carcinoma of the cervix is the most common malignancy among women in India. Although metastatic disease is common, metastasis to breast is rare. A limited number of case reports are published in the world literature. Most of the previous reports of metastatic cervical carcinoma to breast are either autopsy series or widely disseminated disease where no treatment options were available. A rare case of cervical carcinoma presenting as metastasis in breast is reported here where palliative mastectomy improved the general condition of the patient. A female patient aged 58 years was diagnosed and treated for cervical carcinoma, FIGO stage 2B. Four months after the treatment which included both external beam and intracavitory radiotherapy, the patient presented with breast and lung metastasis. Palliative mastectomy was done which improved the general condition of the patient. Metastatic carcinoma of the cervix can present as a case of breast carcinoma. In an appropriate setting, this possibility should be kept in mind. Palliative mastectomy should be offered for patients of cervical carcinoma with metastasis to breast when needed.

Methods Using functional Magnetic Resonance Imaging (fMRI) we mapped sensory cortical responses to clitoral, vaginal, cervical, and nipple self-stimulation. For points of reference on the homunculus, we also mapped responses to the thumb and great toe (hallux) stimulation. Main Outcome Measures fMRI of brain regions activated by the various sensory stimuli. Results Clitoral, vaginal, and cervical self-stimulation activate differentiable sensory cortical regions, all clustered in the medial cortex (medial paracentral lobule). Nipple self-stimulation activated the genital sensory cortex (as well as the thoracic) region of the homuncular map. Conclusion The genital sensory cortex, identified in the classical Penfield homunculus based on electrical stimulation of the brain only in men, was confirmed for the first time in the literature by the present study in women, applying clitoral, vaginal, and cervical self-stimulation, and observing their regional brain responses using fMRI. Vaginal, clitoral, and cervical regions of activation were differentiable, consistent with innervation by different afferent nerves and different behavioral correlates. Activation of the genital sensory cortex by nipple self-stimulation was unexpected, but suggests a neurological basis for women’s reports of its erotogenic quality. PMID:21797981

    The aim of this systematic review was to evaluate and compare the pros and cons of using living donors or brain-dead donors in uterus transplantation programs, 2 years after the first worldwide live birth after uterus transplantation. The Medline database and the Central Cochrane Library were used to locate uterine transplantation studies carried out in human or nonhuman primates. All types of articles (case reports, original studies, meta-analyses, reviews) in English or French were considered for inclusion. Overall, 92 articles were screened and 44 were retained for review. Proof of concept for human uterine transplantation was demonstrated in 2014 with a living donor. Compared with a brain-dead donor strategy, a living donor strategy offers greater possibilities for planning surgery and also decreases cold ischemia time, potentially translating into a higher success rate. However, this approach poses ethical problems, given that the donor is exposed to surgery risks but does not derive any direct benefit. A brain-dead donor strategy is more acceptable from an ethical viewpoint, but its feasibility is currently unproven, potentially owing to a lack of compatible donors, and is associated with a longer cold ischemia time and a potentially higher rejection rate. The systematic review demonstrates that uterine transplantation is a major surgical innovation for the treatment of absolute uterine factor infertility. Living and brain-dead donor strategies are not mutually exclusive and, in view of the current scarcity of uterine grafts and the anticipated future rise in demand, both will probably be necessary.

    Full Text Available Background: Dysfunctional uterine bleeding (DUB is irregular uterine bleeding that occurs in the absence of recognizable pelvic pathology, general medical disease, or pregnancy. It reflects a disruption in the normal cyclic pattern of ovulatory hormonal stimulation to the endometrial lining. About 1–2% of women with improperly managed anovulatory bleeding eventually may develop endometrial cancer but determinants behind the disease are largely unknown. Objective: The present study aimed to find out the determinants of dysfunctional uterine bleeding. Materials and Methods: In this cross-sectional study 50 patients of dysfunctional uterine bleeding (DUB were recruited from different tertiary hospitals in Dhaka city. Clinical parameters have been recorded using a predesigned questionnaire and analyzed using SPSS for Windows version 16.0 and Microsoft Office Excel. Results: In the studied patients, about 38% were suffering from type 2 diabetes mellitus, 12% from obesity and 18% from hypertension. Almost all the patients (96% were suffering from anemia. Histological findings have shown that endometrium of 63% patients were in proliferative phase, about 16% were in secretory phase and 11% patients were with cystic hyperplasia. Ultrasonographic results have shown that about 72% of the patients had bulky uterus. Ninety two percent patients carried more than two pregnancies, and 40% patients carried >5 pregnancies. Conclusion: Bulky uterus and multiple pregnancies may be associated with dysfunctional uterine bleeding in Bangladeshi women.

  16. Hormonal fluctuations during the estrous cycle modulate Heme Oxygenase-1 expression in the uterus

    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.

    The vascular addressins mucosal addressin cell adhesion molecule-1, P-selectin and ICAM-1 permit alpha(4)beta(7)-integrin-expressing DC, especially those of the myeloid lineage (CD11c(+)CD11b(+) DC), to access the pregnant mouse uterus. Injection of blocking monoclonal antibodies against mucosal addressin cell adhesion molecule-1 in P-selectin(-/-) mice or experimental approaches with beta7-integrin(-/-) or ICAM-1(-/-) mice revealed that limited access or absence of CD11c(+)CD11b(+) DC at the maternal/fetal interface negatively affects the frequency, size and functional properties of uterine NK (uNK) cells. Adoptive transfer of DC obtained from WT mice into beta7-integrin(-/-) mice abrogates these effects and emphasizes the importance of DC in uNK cell differentiation. Interestingly, those implantation sites lacking CD11c(+)CD11b(+) DC are characterized by decreased IL-15 and IL-12 mRNA and/or protein levels. Chronic administration of IL-15 in these mice gives rise to uNK cell numbers and size comparable to those of WT mice, whereas additional injection of IL-12 positively affects the IFN-gamma expression of uNK cells. Real-time RT-PCR and protein arrays performed with isolated uterine DC underline the role of DC as a source of IL-15 and IL-12 in the pregnant mouse uterus.

    The aim of this video is to demonstrate the alternative technique of robot-assisted laparoscopic pectouteropexy for uterus preservation in obese patients with pelvic organ prolapse. We present the case report of a 44-year-old patient with apical pelvic organ prolapse. A pelvic examination was performed during a Valsalva maneuver in the dorsal lithotomy position and in the standing position, and the patient was diagnosed with stage III apical prolapse in accordance with the Pelvic Organ Prolapse Quantification system of the International Continence Society (POP-Q: Аа -1, Ва 0, Вр 0, С +2). We performed the procedure, which was developed as an alternative to sacrocolpopexy or sacrouteropexy, as described by Banerjee and Noé (Arch Gynecol Obstet 284:24-28, 2011). Pectouteropexy is a new method for prolapse surgery that uses the lateral parts of the iliopectineal ligament for bilateral mesh fixation of the descended structures and provides strong apical support. We believe that robot-assisted laparoscopic pectouteropexy is a valuable alternative approach for uterus-preserving pelvic organ prolapse surgery owing to its better robot maneuverability, reduced operating time, and better visualization in obese patients.

    Uterine samples were either rapidly frozen in liquid nitrogen or placed in Bouin's fixative. A commercial primary polyclonal antibody made in rabbits against human recombinant basic fibroblast growth factor (bFGF) was used. Western blot analysis indicated that the antibody was specific for bFGF and did not react with acidic FGF. The primary antibody was followed by either goat anti-rabbit immunoglobulin G (IgG) conjugated to the fluorescent phycobiliprotein tracer phycoerythrin or biotinylated goat anti-rabbit IgG and a biotin-avidin-peroxidase complex. Specificity controls using adjacent sections were carried out by (i) substituting normal rabbit sera for the primary antisera, (ii) omitting the primary antisera or (iii) extracting sections with NaCl (2 mol l-1) prior to the immunochemical procedures. No binding of the antibody was observed with any of the specificity control sections. The connective tissue stroma and the basal lamina associated with uterine glandular and surface epithelial layers were positive for bFGF. Localization was not observed within surface or glandular epithelial cells. The basal lamina and endothelial cells associated with blood vessels within the uterus and the smooth muscle cells of the myometrium were positive for bFGF. There were no differences in uterine localization patterns or intensity during the oestrous cycle or after ovariectomy and steroid hormone supplementation. These studies demonstrate the specific localization of bFGF within the mouse uterus.

    Full Text Available The presence of two genital tumors at the same time is a relatively unknown fact. They are rare and account for 0,63% of all genital malignancies. If endometrial carcinoma has affected only endometrium, then this is called stage (IA, if endometrial carcinoma has affected only one half of the miometrium, this is (IB, while (IIIA tumor spreads to serosa or adnexa. In carcinoma localized on the ovary, without rupture of the capsule, the stage is (IA, while ovary carcinoma that affected the oviduct or uterus is (IIA.A female, 55 years old, was hospitalized in the Gynecology and Obstetrics Clinic Kragujevac, Clinical Center Kragujevac because of the surgical operation, and the tumor that filled the whole of the small pelvis. Immunohistochemically, the expressions of ER, PR and HER 2 receptors were determined.Women with independent primary endometrial uterus and ovary tumors have the prognosis similar to those of women with a separate form of this disease.Risk factors and clinical indicators of results in women with synchronized tumors are different from those based on histological division. Women with synchronized tumors are mostly younger, obese, premenopausal and barren. Patients with serious endometrial carcinomas look like patients with ovary carcinomas. In the future, it will be necessary to provide better evaluation of etiology of these diseases. In addition, the molecular diagnoses of tumor in endometrium and ovary will provide us with real confirmation.

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

    Directory of Open Access Journals (Sweden)

    2014-05-01

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

    The mRNA expression patterns of activin beta(A) and follistatin in the uterus and embryo, the mRNA expression of the activin receptor II in the embryo, and the localization in the uterus of the immunoreactive activin beta(A) and the receptor II proteins in the uterus were examined at gestation days 7-12 after ovulation in pig. Activin was located predominantly at the mesometrial side of the uterus during all stages of pregnancy studied. Follistatin mRNA was absent in the uterus during these stages, suggesting that activin of uterine origin is not inhibited by intra-uterine follistatin. The receptor was localized throughout the glandular and luminal epithelium of the uterus. In the embryo, activin was expressed predominantly in the epiblast before unfolding, but after unfolding of the epiblast activin expression shifted to the trophoblast. The expression pattern of follistatin mRNA was contrarily to that of activin, i.e., before unfolding predominantly in the trophoblast (days 8-9), and shifted to the epiblast at day 10. During streak stages, follistatin was detected in the node and primitive streak. Activin receptor II mRNA was first detected at day 8 in the embryoblast. At day 11, it was expressed in trophoblast cells near the epiblast, and in the first ingressing mesoderm cells. During the streak stages, it was expressed predominantly in the trophoblast. The presence of activin and its receptor in uterine epithelium and early embryonic tissues indicate that both embryonic and uterine activin are involved in intra-uterine processes, such as attachment and early embryonic development.

    Full Text Available We report a rare case of obstructed hemivagina and ipsilateral renal agenesis (OHVIRA syndrome with a didelphic uterus. A 22-year-old female presented with infertility for one year. Imaging studies revealed an absent left kidney, massive hematometrocolpos on the left side with normal other side. She was diagnosed with OHVIRA syndrome. She underwent septostomy of the vaginal septum, drainage of hematometrocolpos and hysterolaparoscopy that showed a bicornuate uterus and hematosalpinx. Given the rarity of the syndrome it is frequently misdiagnosed. Delayed diagnosis can lead to endometriosis.

    Full Text Available Papillary serous carcinoma of the uterine cervix (PSCC is a very rare tumor, and is a recently described variant of cervical adenocarcinoma. We experienced a case of stage IV PSCC. The main tumor existed in the uterine cervix and invaded one third of the inferior part of the anterior and posterior vaginal walls. Furthermore, it had metastasized from the para-aortic lymph nodes to bilateral neck lymph nodes. Immnoreactivity for CA125 was positive, whereas the staining for p53 and WT-1 were negative in both the original tumor and the metastatic lymph nodes. We administered six courses of paclitaxel and carboplatin combination chemotherapy against this advanced PSCC. The PSCC therefore dramatically decreased in size. The main tumor of the uterine cervix showed a complete response by magnetic resonance imaging (MRI, and more than 95% of the tumor cells in the cervix had microscopically disapperared. This is the first report of PSCC in which combination chemotherapy was used and showed a remarkable response.

    Conclusion: A literature review revealed that this was a rare case of combined ABC–SCC associated with HPV 31 infection. In this case, the ABC component did not affect the tumor stage because it was confined to the cervix. However, we must avoid overestimating the clinical stage because the ABC component is thought to be a benign lesion.

However, depth of primary tumor invasion is also important in cervical cancer prognostic analysis. In this study, the objective was to determine if MLNR can be used to define a high-risk category of patients with squamous cell carcinoma of the cervix (SCC. And we combined MLNR and depth of invasion to investigate whether prognosis of SCC can be predicted better.  Patients and methods: We performed a retrospective review of patients with SCC who underwent radical hysterectomy and pelvic lymphadenectomy at QiLu Hospital of Shandong University from January 2007 to December 2009. Prognostic factors for disease-free survival (DFS and overall survival (OS were identified by univariate and multivariate analyses.  Results: One hundred and ninety-eight patients met the inclusion criteria and were included in the analysis. By cut-point survival analysis, MLNR cutoff was designed as 0.2. On multivariate analysis, an MLNR >0.2 was associated with a worse OS (hazard ratio [HR] =2.560, 95% CI 1.275–5.143, P=0.008 and DFS (HR =2.404, 95% CI 1.202–4.809, P=0.013. Depth of invasion cutoff was designed as invasion >1/2 cervix wall and was associated with a worse OS (HR =1.806, 95% CI 1.063–3.070, P=0.029 and DFS (HR =1.900, 95% CI 1.101–3.279, P=0.021. In addition, subgroup analysis revealed significant difference in OS and DFS rates between different MLNR categories within the same depth of invasion category (P<0.05, however, not between different depth of invasion categories within the same MLNR category (P>0.05.  Conclusion: MLNR may be used as the independent prognostic parameter in patients with SCC.

    Full Text Available Cervical cancer is the second most common cancer in women. Neoadjuvant chemotherapy for patients with locally advanced cervix cancer has comparable benefits to concurrent chemoradiotherapy (CCRT, but with fewer side effects. This systematic review aims to provide a comprehensive summary of the benefits of neoadjuvant chemotherapy for the management of locally advanced cervix cancer from stage IB2 (tumor >4.0 cm to IIIB (tumor extending to the pelvic wall and/or hydronephrosis. Our primary objective was to assess benefits in terms of survival. The data source included the USA national library of medicine, Medline search, and the National Cancer Institute PDQ Clinical Protocols. Inclusion criteria for consideration in the current systematic review included studies published between January 1997 and December 2012. In terms of histology, they had to be focused on squamous cell carcinoma, adenosquamous carcinoma, and/or adenocarcinoma. Patients should be either chemotherapy naïve or cervix cancer chemotherapy naïve, and have a performance status ≤2. The search in the above-mentioned scientific websites led to identify 49 publications, 19 of which were excluded, as they did not meet the inclusion criteria of this systematic review. Therefore only 30 studies were deemed eligible. Data was collected from 1760 patients enrolled in the current systematic review study. The mean age was 45.2 years. The mean tumor size was 4.7 cm. The most commonly used chemotherapies were cisplatin doublets. Paclitaxel was the most commonly used chemotherapeutic agent in the doublets. The mean chemotherapy cycles were 2.7. After chemotherapy, patients underwent surgery after a mean time of 2.5 weeks. The standard operation was radical hysterectomy with pelvic lymphadenectomy. Chemotherapy achieved an objective response rate of 84%. The 5-year progression-free survival and overall survival were 61.9% and 72.8% respectively. The treatment protocol was associated

    Full Text Available 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 to 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 subclinical pregnancy toxemia 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<0.05. The predicted miRNA and associated target genes contributed to several biological processes, including apoptosis, biological adhesion, biological regulation, cellular component biogenesis, cellular process, developmental process, immune system process, localization, metabolic process, multicellular organismal process, reproduction, and response to stimulus. The target genes were involved in several pathways including angiogenesis, cytoskeletal regulation, hypoxia response via HIF activation, interleukin signaling, ubiquitin proteasome and VEGF signaling pathway. In conclusion, genes

    Cisplatin and paclitaxel both can cause peripheral neurotoxicity as an adverse effect; however, central nervous system neurotoxicity in the form of seizures is rare. We report a case of a 36-year-old female patient of metastatic carcinoma cervix, who developed seizure shortly after cisplatin infusion. Her laboratory investigations were within normal limits. Computed tomography scan and magnetic resonance imaging of the brain did not reveal brain primary metastasis or meningeal carcinomatosis. She had no complaints of fever, no signs and symptoms of infection, and no history of seizure nor was she on any medication predisposing to such an event. Excluding several causes, seizure was thought to be most likely related to the chemotherapy and cisplatin was the more likely agent in view of observed temporal relationship with the adverse event.

    We report a case of malignant fibrous histiocytoma (MFH) following carcinoma of the cervix. A 28-year-old female received postoperative radiation of the pelvis, and five years later MFH occurred in the sacral region. After a resection of this tumor, we performed cyclic systemic chemotherapy with cisplatin and adriamycin. The patient is currently doing well. Recently, MFH has been thought to be the most frequent soft tissue tumor in elderly patients, and also occurs frequently as a radiation-induced tumor. Since MFH tends to occur more than ten years after radiation, long-term follow up is important for early detection. We considered that surgical resection was an excellent treatment, while chemotherapy mainly composed of cisplatin was also thought to be effective. (author).

    From August 1978 through December 1980, 119 patients of previously untreated carcinoma of the uterine cervix were treated using RALS, remote afterloading high dose rate intracavitary therapy at our department. The data from 92 out of 119 patients were available for analysis of rectal complication. The incidence of major rectal complications was only 2% (2/92). Uni- and multivariate analyses were used based on the external criterion variable of rectal complication which included even minor injuries. By using these methods, it was clearly indicated that these factors such as TDF of rectum, Z-coordinate of weighted geometric center (WGC-Z), the dose of whole pelvic irradiation, history of chemotherapy and Treponema pallidum hemoagglutination test (TPHA) were important for occurrence of rectal complication. According to discriminant score, 71 out of 92 cases (77%) could be correctly discriminated.

    Purpose : Radiation therapy(RT) is conventionally standard treatment for locally advanced stage for uterine cervix cancer. Recently to improve treatment results, combined chemotherapy and radiation therapy was tried. We retrospectively analysed our experience of 122 patients. Comparison of the results in 45 patients treated with RT alone and 77 patients treated with RT plus chemotherapy was made. Materials and Methods : from January 1985 to December 1991, 122 patients with cervix cancer were treated with whole pelvic external RT and ICR(34 1 ICR, 77 2 ICR, 11 high dose rate ICR) in our department. Forty five patients were treated with RT alone, and 77 patients were treated with combined plus chemotherapy. Mean age was 58 years(range:29-81). Histologic types were 111 squamous cell carcinoma, large cell carcinoma, 3 adenocarcinoma, and 2 adenosquamous cell carcinoma. According to the FIGO stage 6 had stage IA94.9%, 11 had IIA(9.0%), 37 had IIB(30.3%), 3 had IIA(2.5%), 63 had IIB(51.6%), and 2 had stage IV(1.6%). In 77 patients with RT plus chemotherapy, 36 patients were treated with VBP(vinblastin, bleoycin, cisplainum), 39 patients with cisplatinum plus 5-FU and 2 patients with 5-FU. Results : Complete response after external RT(3960cGy-5500cGy)was achieved in 61 patients(50%). He actuarial 5 year and 9 year survival rate was 57.8% and 53.9%, respectively. Five year actuarial survival rate was 63.1% with RT alone(n=45) and 55.9% with RT plus chemotherapy(n=77). Their 5 year survival rate was 35.5% for 1 course of ICR and 67% for 2 courses of ICR. There was statistically significant advantage of survival with RT alone group who were treated with 2 coursed of ICR and dose to the A point{>=}8000cGy(4/25 died). In RT plus chemotherapy group, dose response was not seen and there was no difference in 5 year survival between 1 course and 2 course of ICR(50% vs 56.8%), and dose to point A less than 8000cGy and more than 8000 cGy(55.6% vs 55.7%). There was no significant

    Celik, Suleyman Utku; Besli, Dilara; Sak, Serpil Dizbay; Genc, Volkan

    The thyroid gland is a relatively uncommon site for a metastatic disease, although it is richly supplied with blood. The metastases may originate from various primary sites, mainly kidney, lung, head and neck, and breast. Thyroid metastasis from cervical carcinomas is extremely rare; and only a few cases have been previously reported in the literature. In patient with thyroid nodules and an oncological history, the possibility of thyroid metastasis should be seriously considered. Despite the rarity of the metastasis of cervical carcinoma to the thyroid, it is difficult to say appropriate treatment approach for these lesions. When managing such patients, decision-making should balance the possibility of gaining long-term survival against estimation of the aggressiveness of the disease and its possible complications. Here, a case of thyroid metastasis from a squamous cell carcinoma of the uterine cervix presenting with cervical mass and difficulty in swallowing and its treatment is reported.

    Granulocytic sarcoma is an unusual form of tumefaction caused by acute granulocytic leukemia. On rare occasions, the lesion precedes the leukemic phase and presents as a mass with a normal peripheral white cell count. This report describes the initial manifestation of granulocytic sarcoma by vaginal cytology in a 39-year-old female with Down's syndrome. Six days after admission, the patient died of acute peritonitis following spontaneous perforation of the bowel. Autopsy revealed involvement of cervix, vagina, bowel wall and one pelvic lymph node by granulocytic sarcoma. Bone marrow examination confirmed the preleukemic stage of the disease. Cytologically, the malignant cells occurred singly. No nucleoli were seen. The differential diagnosis between malignant lymphoma and granulocytic sarcoma rests upon a positive naphtol AS-D chloroacetate esterase stain in granulocytic sarcoma. This stain may be performed on paraffin-embedded sections or on smears.

    1984-09-01

    The effects of adrenoceptor agonists and antagonists on the contractile activity of cervical strips from early pregnant and nonpregnant women were studied. Noradrenaline and the alpha-adrenoceptor agonist, phenylephrine, had a stimulatory effect on smooth muscle activity. This response could be blocked totally by the alpha-adrenoceptor antagonist, phenoxybenzamine. Isoprenaline, known to be a beta-adrenoceptor agonist with some alpha-adrenoceptor activity, had stimulatory and inhibitory effects, whereas the beta 2-adrenoceptor agonist, terbutaline, exhibited a pure inhibitory action. The inhibitory effects of isoprenaline and terbutaline were totally blocked by the beta-adrenoceptor antagonist propranolol. In pregnant patients, the sensitivity to noradrenaline was significantly higher, and the inhibitory action of terbutaline was less pronounced, which indicated the predominance of alpha-receptor activity in the uterine cervix during pregnancy.

    Chronic inflammation of the cervix can develop cervical stenosis with infertility and cervical congestion is related with the cervical cancer. We create a review of main etiological agents and methods of screening and diagnosis. We also make a brief review of modern therapeutic approach. We follow the utility of LLLT through the following aspects: evolution, indications, results of Babeş-Papanicolau screening, cytology, clinical aspects. The results of the study will allow the complex system of treatment to be used in a large category of women. We appreciate that the procedure (used in our center also) will decrease the cervical pathology, the morbidity inside the treatment, the mortality through the evolution of cervical cancer. We propose the applicability for outpatients first and then as an integrated treatment method inside hospitals for a wide access.

    AIM: The aim of this study was to quantify the impact of different types and magnitudes of dosimetric uncertainties in cervix cancer brachytherapy (BT) on tumour control probability (TCP) and normal tissue complication probability (NTCP) curves. MATERIALS AND METHODS: A dose-response simulation...... study was based on systematic and random dose uncertainties and TCP/NTCP models for CTV and rectum. Large patient cohorts were simulated assuming different levels of dosimetric uncertainties. TCP and NTCP were computed, based on the planned doses, the simulated dose uncertainty, and an underlying TCP....../NTCP model. Systematic uncertainties of 3-20% and random uncertainties with a 5-30% standard deviation per BT fraction were analysed. RESULTS: Systematic dose uncertainties of 5% lead to a 1% decrease/increase of TCP/NTCP, while random uncertainties of 10% had negligible impact on the dose-response curve...

    2008-01-01

    A noninvasive optical diagnostic system for detection of cancerous and precancerous lesions of the cervix was evaluated in vivo. The optical system included a fiber-optic probe designed to measure polarized and unpolarized light transport properties of a small volume of tissue. An algorithm for diagnosing tissue based on the optical measurements was developed that used four optical properties, three of which were related to light scattering properties and the fourth of which was related to hemoglobin concentration. A sensitivity of {approx}77% and specificities in the mid 60% range were obtained for separating high grade squamous intraepithelial lesions and cancer from other pathologies and normal tissue. The use of different cross-validation methods in algorithm development is analyzed, and the relative difficulties of diagnosing certain pathologies are assessed. Furthermore, the robustness of the optical system for use by different doctors and to changes in fiber-optic probe are also assessed, and potential improvements in the optical system are discussed.

    Granulomas of the female genital tract are rare and usually occur after operative procedures. A patient with rheumatoid arthritis presented with vaginal discharge and bleeding with ulcerative, red, friable lesions of the cervix, which extended to the bladder floor and the right upper vaginal wall. Cervical biopsy was highly suggestive of rheumatoid nodules. This prompted revision of the diagnosis of tuberculosis, which was suspected several months earlier when pulmonary and renal lesions were noted. The cervico-vaginal lesions did not respond to local steroid treatment and improved when the systemic steroid dose was increased; however, they recurred on tapering the dose. Rheumatoid nodules can occur in the genital tract, which poses diagnostic and treatment challenges.

    Background. Cervical carcinoma is the only gynecological tumor still being staged mainly by clinical examination and only a limited use of diagnostic radiology. Cross sectional imaging is increasingly used as an aid in the staging procedure. We wanted to assess the impact of magnetic resonance imaging (MRI) in addition to the clinical staging of patients with carcinoma of the uterine cervix. Material and methods. A retrospective single-centre analysis of 183 women referred to a tertiary referral centre for gynecological tumors (<= 65 years old) with cervical cancer diagnosed between January 1, 2003 and December 31, 2006 who have undergone an MRI investigation before start of treatment. Patient records were retrospectively reviewed and any change of the planned treatment after the MRI examination was noted. Results. In patients with cervical carcinoma FIGO stage Ia2-IIa treated surgically, the treatment plan was altered due to MRI results in 10/125 patients. In the smaller group of patients with clinically more advanced disease receiving radio-chemotherapy, the treatment plan was altered in 12/58 patients. Reasons for changing the treatment plan after MRI were findings indicating a higher (n = 8) or lower (n = 5) local tumor stage, findings of para aortic nodal disease (n = 4) or difficulty to clinically examine the patient due to obesity (n = 2). MRI was also an aid in deciding whether or not to offer fertility preserving treatment in three cases. Conclusion. The use of MRI affects treatment planning in patients with cancer of the uterine cervix. The impact is more obvious in more advanced stages of disease and in patients who are difficult to examine clinically due to, for example body constitution. The result of MRI is also an aid in deciding whether or not a fertility preserving operation is feasible

    Background: Adenoma malignum, also known as minimal deviation adenocarcinoma, is a subtype of mucinous adenocarcinoma of the cervix. Purpose: To evaluate the clinical, pathologic, and imaging features of the adenoma malignum of the uterine cervix. Material and Methods: We retrospectively analyzed the CT and MRI findings in 13 patients: size, endoluminal fluid, appearance of the solid and cystic component, margin, enhancement, characteristics of locules of the cystic lesion, tumor spread, and associated ovarian lesion. Clinical and pathologic features were determined in 24 patients. Results: The mean of the major tumor diameter was 4.1 cm (range, 2.2 - 6.5 cm). In the imaging features, 77% of 13 tumors demonstrated endoluminal fluid. All tumors showed enhancing solid components; 62% were multicystic and 38% had solid lesions. Most solid lesions exhibited an irregular margin (80%). The locules of the multicystic lesions tended to have smooth margins (75%), to have an average major diameter of {<=}1 cm (88%), and to be 11 - 20 in number (75%). The solid lesions were associated with invasion and metastases (60%). Clinically, 38% of 24 patients had watery discharge and 13% had Peutz-Jeghers syndrome, while pathologically, most patients were low stage (I or II) (83%). Over the 2-year follow-up of 17 patients, 82% was free from disease. The patients with more aggressive tumors or an unfavorable prognosis that manifested as tumor recurrence or metastasis tended to have invasion, watery discharges, high stages (III or IV) (100%) and solid lesions, metastases, and associated ovarian lesions (67%). Conclusion: Awareness of imaging features as well as clinicopathologic manifestations of adenoma malignum can aid in accurate diagnosis, treatment, and prediction of prognosis.

    1988-12-01

    The diagnostic value of X-ray computed tomography scan for early detection of recurrence and/or metastasis were analyzed as an index of a sensitivity, a specificity, a positive predictive value, a negative predictive value and an accuracy among one hundred and thirty-one patients with carcinoma of the cervix as part of post-treatment evaluation during a period from 1980 to 1987. The diagnostic points of CT scan was the following criteria which including (1) parametrial involvement, (2) enlargement of uterine cervix, (3) invasion to vaginal wall, (4) bladder and/or rectal invasion, (5) pyometra, (6) enlargement of pelvic and/or paraaortic lymph nodes, (7) laterality of pelvic muscle, (8) intrapelvic abnormal shadow or ascites retension, (9) hydronephrosis, and (10) distant metastasis. (1) Among the patients treated with surgery, accuracy of each diagnostic point for early detection of recurrence was as follows: (8) 73%, (6) 60%, (9) 47%, (10) 47%, (3) 40%, (1) 33%, (4) 27%, (7) 27%, respectively. (2) Among the patients reated with radiotherapy, accuracy of each diagnostic point for early detection of recurrence was as follws: (1) 65%, (8) 64%, (5) 63%, (4) 61%, (10) 58%, (6) 55%, (9) 53%, (2) 42%, (3) 41%, (7) 41%, respectively. (3) Among the patients treated with surgery and radiotherapy, accuracy of each diagnostic point for early detection of recurrence was as follows: (8) 76%, (10) 76%, (9) 57%, (6) 52%, (1) 48%, (4) 43%, (7) 33%, (3) 19%, respectively. In conclusion, CT findings such as paraaortic lymphadenopathy and invasion to vaginal wall including distant metastasis were most important for early detection of recurrence during the follow-up study.

    Full Text Available Background: Mast cells are heterogeneous group of immune cells involved in multiple biological events. The significance of mast cells in uterine tumor surveillance has been studied with conflicting results. The presence of mast cell in tumor has been described as evidence of a host immunologic anti tumor response and if they are abundant the prognosis is good. However in other studies, with the help of different granules of mast cell, it is said to be very closely related with angiogenesis and tumor invasion. The study aims to analyze the histomorphologic changes with special reference to mast cells in different neoplastic and non neoplastic disease of uterine cervix, and also the relationship of the mast cell population with degree of anaplasia and mitotic figures.Materials and methods: Cervical biopsies received in the department of Pathology for HPE were stained with H& E stain and toludine blue for the identification of mast cellResult: Out of a total of 100 cases, 82 were non neoplastic cases with the mean mast cell count of 83.73 and mean age of patient being 44.30 year. Eighteen neoplastic cases were included which had mean mast cell count of 13.5 and mean age of 49.5 year.Conclusion: Mast cell was found to be highest in non Neoplastic lesion with increase count in polypoidal cervicitis. There was a statistical significance variation between mast cell count in neoplastic and non Neoplastic disease of the cervix. However,role of age in mast cell count was least significant.DOI: http://dx.doi.org/10.3126/jpn.v4i8.11594 Journal of Pathology of Nepal; Vol.4,No. 8 (2014 658-662

    We report the MRI features of two cases of unicornuate uterus and occluded rudimentary horn. In one patient pregnancy had occurred in the occluded horn, prompting to urgent resection. The second patient illustrates more conventional findings in occluded rudimentary horn. In both cases MRI was able to correctly characterise the nature of the developmental anomaly. Furthermore, on the basis of signal intensities, differentiation between distended lumen due to blood accumulation and amniotic sac in the case of pregnancy could be made. Because of its high accuracy in determining the type of anomaly present, the lack of ionizing radiation, and the ability to evaluate, with the exception of the fallopian tubes, the entire genitourinary tract, MR imaging is essential and plays a key role in the evaluation of women who are consulting for infertility.

    Lupton, M L

    1999-01-01

    Embryo adoption is a way of having children for couples who wish to share a pregnancy experience but have neither eggs nor sperm to realise their dream. This type of situation could occur where the wife has had a hysterectomy, while her husband has an extremely low sperm count. The donors of embryos are usually couples who have completed their families. The artificial womb will duplicate the technology of a natural womb so as to enable the child to gestate and develop physically to maturity. This ability will enable the artificial womb to be used to rescue severely premature babies who would otherwise have died and allow them to develop normally to term. Legislation will be required to regulate situations where an entire pregnancy is sustained in an artificial uterus. Clarity as to parenthood in particular will need to be regulated.

    1997-12-01

    Arteriovenous malformations (AVM) are rare entities in gynecology, with only 73 cases reported in the literature. Most commonly they present with vaginal hemorrhage, but other presentations such as congestive heart failure, postmenopausal bleeding, and an asymptomatic mass have been described. These lesions may be congenital or acquired. Acquired lesions are believed to follow trauma or may arise after choriocarcinoma or other gynecologic malignancies. Diagnosis can rapidly be made with color flow Doppler ultrasound or angiography. Additionally, they have been detected using hysteroscopy, hysterosalpingogram, and computerized tomography. Acute management consists of hemodynamic stabilization and possibly placement of a Foley bulb in the uterus or methylergonovine injection. Ultimate treatment depends on the patients desire for fertility. Embolization therapy is variably successful and may allow the preservation of reproductive capacity. To date, five pregnancies after embolization have been reported with varying outcomes. If pregnancy is not desired or embolization fails, hysterectomy remains the treatment of choice.

    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.

  13. Selection of internal control genes for real-time quantitative PCR in ovary and uterus of sows across pregnancy.

    Directory of Open Access Journals (Sweden)

    María Martínez-Giner

    Full Text Available BACKGROUND: Reproductive traits play a key role in pig production in order to reduce costs and increase economic returns. Among others, gene expression analyses represent a useful approach to study genetic mechanisms underlying reproductive traits in pigs. The application of reverse-transcription quantitative PCR requires the selection of appropriate reference genes, whose expression levels should not be affected by the experimental conditions, especially when comparing gene expression across different physiological stages. RESULTS: The gene expression stability of ten potential reference genes was studied by three different methods (geNorm, NormFinder and BestKeeper in ovary and uterus collected at five different physiological time points (heat, and 15, 30, 45 and 60 days of pregnancy. Although final ranking differed, the three algorithms gave very similar results. Thus, the most stable genes across time were TBP and UBC in uterus and TBP and HPRT1 in ovary, while HMBS and ACTB showed the less stable expression in uterus and ovary, respectively. When studied as a systematic effect, the reproductive stage did not significantly affect the expression of the candidate reference genes except at 30d and 60d of pregnancy, when a general drop in expression was observed in ovary. CONCLUSIONS: Based in our results, we propose the use of TBP, UBC and SDHA in uterus and TBP, GNB2L1 and HPRT1 in ovary for normalization of longitudinal expression studies using quantitative PCR in sows.

    The aim of this study was to examine whether avian beta-defensin proteins (avbetaDs) exist in the oviduct, and whether those in the uterus are secreted to the eggshell membrane and eggshell. The oviducts of White Leghorn hens at different times of egg formation, eggshell membrane, and eggshell were used. The presence of immunoreactive (ir) avbetaD-3, -11, and -12 was examined by immunohistochemistry and western blot. Two or three types of avbetaDs were identified in the mucosal surface epithelial cells in each oviductal segment. The density of ir-avbetaD-3 and -12 in the uterus was decreased after the egg entered this segment. Western blot analysis confirmed the presence of ir-avbetaD-3, -11, and -12 in the uterus. In the eggshell membrane, only ir-avbetaD-3 was detected on the surface of fibers at the outer layer of the membrane. The ir-avbetaD-3, -11, and -12 were identified in the eggshell matrix by western blot. These results suggest that the surface epithelial cells are the major sites where avbetaDs proteins exist, and the avbetaDs secreted by the uterus cells are likely to be incorporated in the eggshell membrane and eggshell. These avbetaDs may play roles in the innate host defense of the oviduct and egg surface.

  15. Cytological evaluation of inflammation of the uterus and influence of endometritis on selected reproductive parameters in dairy cows

    Full Text Available There were two aims of this study. One was to evaluate the postpartum state of the reproductive system in cows based on ultrasonography, bacterial culture, and cytological examination of the uterus. The other was to determine whether postpartum endometritis affects the subsequent state of the endometrium, and, in consequence, selected reproductive parameters in cows. The study was conducted on 60 cows: the experimental group of 30 cows with endometritis, and 30 cows free of uterine inflammation (control. The percentage of leukocytes in both groups was similar only on day 5 of postpartum. In all subsequent tests (26, 40, 61 d postpartum, the percentage of leukocytes in the experimental group was statistically significantly higher than in the control (P < 0.001, both in samples collected with a brush and in lavage samples. Involution of the uterus in the experimental group was also slower (P < 0.001. The analysed reproductive parameters were markedly less favourable in the experimental group than in the control. The study showed that postpartum inflammation of the uterus can persist for a long time in the form of endometritis, causing substantial deterioration of reproductive parameters in cows. The authors suggest that cytological evaluation of the uterus, preferably using a brush, should be performed as soon as possible after parturition, even before day 21, up to which time puerperal metritis may still persist. Evaluation of the inflammatory process based on the number of leukocytes and the quality of endometrial cells is important.

    Full Text Available Somatovisceral reflex suggested that the somatic stimulation could affect visceral function like acupuncture which treats diseases by stimulating acupoints. The neuronal connection between somatic point and visceral organ was not clear. Uterine pain referred to the groin region has long been recognized clinically. Wesselmann, using neurogenic plasma extravasation method, showed that uterine pain was referred to the groin region through a neuronal mechanism (Wesselmann and Lai 1997. This connection could be considered through the somatovisceral reflex pathway. However, the relay center of this pathway is still not clearly identified. In the present study, bee venom was injected in the groin region to induce central Fos expression to map the sensory innervation of groin region. Pseudorabies virus (PrV, a transneuronal tracer, was injected in the uterus to identify the higher motor control of the uterus. Immunohistochemistry staining revealed the Fos expression and PrV-infected double-labeled neurons in the nucleus of solitary tract (NTS, the dorsal motor nucleus of vagus (DMX, and the paraventricular hypothalamic nucleus (PVN. These results suggest a somatoparasympathetic neuronal connection (groin-spinal dorsal horn-NTS/DMX-uterus and a somatosympathetic neuronal connection (groin-spinal dorsal horn-NTS-PVN-uterus. These two neuronal connections could be the prerequisites to the neuronal basis of the somatovisceral reflex and also the neuronal mechanism of acupuncture.

    To assess reproductive outcomes in patients after surgical correction of septate uterus. Observational retrospective study (Canadian Task Force classification II-2). Two university hospitals. One hundred twenty-eight patients with primary infertility or recurrent miscarriage with partial (American Fertility Society [AFS] class Va), complete (AFS class Vb), or fundic (AFS class VI) septate uterus. Metroplasty is the current method of choice for surgically correcting septate uterus. The procedure and its indications are a matter of debate. Metroplasty via hysteroscopy. Outcomes including the numbers of pregnancies, first live births (FLBs), and miscarriages were determined. After metroplasty, 78 women (60.9%) became pregnant, and 70 live neonates were delivered. The FLB rate in infertile women was 53.1%. Of the 25 pregnancies, 13 (52%) resulted from assisted reproductive technology. In women who experienced recurrent miscarriage, the miscarriage rate was significantly improved. Outcomes (miscarriages and FLBs) differed significantly according to anatomical type of septum after surgery. Hysteroscopic septum resection is accompanied by safe improvement in reproductive performance in patients with symptoms of AFS class V/VI septate uterus. Copyright © 2013 AAGL.

    Full Text Available In the canine species, the precise mechanisms of pregnancy maintenance and the initiation of parturition are not completely understood. The expression of genes encoding the receptors for estrogen (ERα mRNA and oxytocin (OTR mRNA was studied in the endometrium and myometrium during pregnancy and parturition in dogs. Real-time PCR was performed to quantify the levels of ERα mRNA and OTR mRNA in the uterus of bitches during early (up to 20 days of gestation, mid (20 to 40 days and late pregnancy (41 to 60 days, and parturition (first stage of labor. All tissues expressed ERα and OTR mRNA, and are thus possibly able to respond to eventual estrogen and oxytocin hormonal stimuli. No statistically significant differences in the expression of ERα mRNA were verified in the endometrium and myometrium throughout pregnancy and parturition, but expression of OTR mRNA increased at both parturition and late pregnancy. We concluded that the increase of endometrial and myometrial OTR mRNA expression in dogs is not an event dependent on estrogenic stimulation. Moreover, the contractility response of the canine uterus to oxytocin begins during pregnancy and maintains myometrial activity. The expression of OTR mRNA in canine uterine tissues varied over time, which supports an interpretation that the sensitivity and response to hormone therapy varies during the course of pregnancy and labor. Further studies are needed to elucidate the factors underlying the synthesis of uterine oxytocin receptors and the possible role of ERβ rather than ERα in the uterine tissues during pregnancy and parturition in dogs.

    The influence of stress on embryo implantation is not well understood. Prior studies have focused on later gestational stages and the long-term impact of stress on immune function. The objective of this study is to investigate the effects of restraint stress on the immune parameters and the oxidative states of the uterus during implantation. In this study, pregnant CD1 mice were subjected to restraint stress (4 h/d) on embryonic day 1 (E1) and sacrificed on E3, E5, and E7. Maternal plasma corticosterone (CORT) secretion and implantation sites in the uterus were examined. The uterine (excluding embryos) homogenate and uterine lymphocytes were collected to examine oxidative stress states and associated immune parameters. The results demonstrated that restraint stress increased maternal plasma CORT secretion and reduced the number of implantation sites by 15.3% on E5 and by 26.1% on E7. Moreover, restraint stress decreased the density of uterine natural killer (uNK) cells in the endometrium by 22.1-47.9% and increased the density of mast cells in the myometrium by 55.6-76.9%. Restraint stress remarkably decreased the CD3(+)CD4(+) T/CD3(+)CD8(+) T cell ratio (by 26.2-28.9%) and attenuated uterine lymphocyte proliferation and secretion of cytokines. In addition, restraint stress threatened the intracellular equilibrium between oxidants and antioxidants, resulting in decreased glutathione peroxidase (GSH-PX) (32.2% and 45.7%), superoxide dismutase (SOD) (15.5% and 26.1%), and total antioxidant capacity (T-AOC) (18.4% and 18.2%) activities and increased malondialdehyde (MDA) (34.4% and 43.0%) contents on E5 and E7. In conclusion, these findings demonstrate that restraint stress causes abnormal implantation and negatively impacts immune parameters in association with oxidative stress in mice.

    Full Text Available Aim: To investigate whether, intraocular pressure (IOP is affected when there is a second fetus in the uterus during pregnancy. Materials and Methods: Eighty eyes of 40 twin pregnancies (TwPs, 80 eyes of 40 singleton pregnancies (SiPs and 80 eyes of 40 non-pregnant females (NoPs were included in the study. Statistical Analysis: Repeated measurements analysis of variance with two factors, one-way analysis of variance (ANOVA and theTukey′s multiple comparison test were used. Results: The mean IOP (MIOP values in TwPs were 14.29 ± 1.28, 11.48 ± 1.20, and 9.81 ± 1.36 mmHg and the MIOP values in SiPs were 14.42 ± 0.95, 13.12 ± 0.75, and 10.97 ± 0.89 mmHg in subsequent trimesters. The MIOP values in NoPs were 14.77 ± 1.18, 14.92 ± 1.33, and 15.08 ± 0.89 mmHg in subsequent 3-month measurements. The results show that the MIOP values for the TwPs group were significantly lower than the SiPs in all trimesters. Conclusions: During pregnancy, the number of fetuses in the uterus is an indirectly important factor that influences the decrease in IOP. We hypothesize that the increased ocular hypotensive effect of TwPs is most likely related to the presence of higher levels of hormones, particularly estrogen, progesterone and relaxin compared with SiPs.

Here, we present a rare case of primary diffuse large B-cell lymphoma (DLBCL of uterus and broad ligament in a 63-year-old female. The patient presenting with lower abdominal distention was referred to our hospital. Subsequent abdominal and pelvic ultrasound revealed the presence of a large mass, which was highly suspected as subserosal uterine leiomyoma. A large tumor was found with unclear boundary with right posterior wall, broad ligament and bilateral adnexa during surgery. Her uterus and the tumor of a broad ligament and bilateral adnexa were all excised as a result. Postoperative pathological examination showed DLBCL in uterus and broad ligament. Further examinations excluded metastatic diseases, which supported the diagnosis of primary DLBCL of the uterus and broad ligament. The patient received six cycles of R-CHOP (21 days regimen. During the 8 months follow-up, no evidence of disease recurrence was identified. As the prevalence of primary extranodal lymphoma is increasing, the details of this rare case may highlight the importance and facilitate treatment of similar diseases. A summary focusing on the presentation and prognosis as well as a review of current management is also discussed.

    The purpose of this study was to evaluate the effectiveness and safety of transcervical Foley catheter with and without oxytocin versus oxytocin alone for labour induction with unfavourable cervix. This trial enrolled 108 women with singleton pregnancies presented for labour induction with unfavourable cervix. Patients were randomly assigned to receive Foley catheter alone (I), Foley catheter plus oxytocin (II) or oxytocin alone (III). Outcomes were analysed in terms of success of induction, induction delivery interval, route of delivery, dose and duration of oxytocin, and complications. Successful normal vaginal delivery was more common in group I (p = .02) compared to group III. Induction delivery time was statistically shorter in group II and group III (p oxytocin dose and duration (p oxytocin increases success rate of normal vaginal delivery; however, it has a longer induction delivery interval with similar complications.

    Different methods of treatment have been debated over the years for Stage IB carcinoma of the cervix, especially in view of the results and complications. We have reviewed the experience of the Norwegian Radium Hospital for carcinoma of the cervix, Stage IB, for the years 1968, 1969, and 1970; most of the patients receive preoperative intrauterine and intravaginal radium, followed by radical hysterectomy and pelvic lymphadenectomy; if the nodes are involved, they also receive external pelvic irradiation. During this period, 437 patients had Stage IB; the 5 year survival was 80.2 per cent (not corrected). We focused our attention on lymphedema following such a method of treatment; of 402 patients operated upon, 23.4% developed lymphedema ranging from mild to moderate to severe; 20 patients (5%) had severe lymphedema; factors involved are analyzed.

    The ability to provide safe and effective pharmacotherapy during obstetric complications, such as preterm labor or postpartum hemorrhage, is hampered by the systemic toxicity of therapeutic agents leading to adverse side effects in the mother and fetus. Development of novel strategies to target tocolytic and uterotonic agents specifically to uterine myocytes would improve therapeutic efficacy while minimizing the risk of side effects. Ligand-targeted liposomes have emerged as a reliable and versatile platform for targeted drug delivery to specific cell types, tissues or organs. Our objective was to develop a targeted drug delivery system for the uterus utilizing an immunoliposome platform targeting the oxytocin receptor. We conjugated liposomes to an antibody that recognizes an extracellular domain of the oxytocin receptor. We then examined the ability of oxytocin receptor-targeted liposomes to deliver contraction-blocking (nifedipine, salbutamol and rolipram) or contraction-enhancing (dofetilide) agents to strips of spontaneously contracting myometrial tissue in vitro (human and mouse). We evaluated the ability of oxytocin receptor-targeted liposomes to localize to uterine tissue in vivo, and assessed if targeted liposomes loaded with indomethacin were capable of preventing lipopolysaccharide-induced preterm birth in mice. Oxytocin receptor-targeted liposomes loaded with nifedipine, salbutamol or rolipram consistently abolished human myometrial contractions in vitro, while oxytocin receptor-targeted liposomes loaded with dofetilide increased contraction duration. Nontargeted control liposomes loaded with these agents had no effect. Similar results were observed in mouse uterine strips. Following in vivo administration to pregnant mice, oxytocin receptor-targeted liposomes localized specifically to the uterine horns and mammary tissue. Targeting increased localization to the uterus 7-fold. Localization was not detected in the maternal brain or fetus. Targeted

    In vivo Raman spectroscopy is being projected as a new, noninvasive method for cervical cancer diagnosis. In most of the reported studies, normal areas in the cancerous cervix were used as control. However, in the Indian subcontinent, the majority of cervical cancers are detected at advanced stages, leaving no normal sites for acquiring control spectra. Moreover, vagina and ectocervix are reported to have similar biochemical composition. Thus, in the present study, we have evaluated the feasibility of classifying normal and cancerous conditions in the Indian population and we have also explored the utility of the vagina as an internal control. A total of 228 normal and 181 tumor in vivo Raman spectra were acquired from 93 subjects under clinical supervision. The spectral features in normal conditions suggest the presence of collagen, while DNA and noncollagenous proteins were abundant in tumors. Principal-component linear discriminant analysis (PC-LDA) yielded 97% classification efficiency between normal and tumor groups. An analysis of a normal cervix and vaginal controls of cancerous and noncancerous subjects suggests similar spectral features between these groups. PC-LDA of tumor, normal cervix, and vaginal controls further support the utility of the vagina as an internal control. Overall, findings of the study corroborate with earlier studies and facilitate objective, noninvasive, and rapid Raman spectroscopic-based screening/diagnosis of cervical cancers.

    In colposcopic evaluation of the cervix, acetic acid of 3 to 5% is commonly used for identification of preneoplastic and neoplastic cells. Acetic acid is a known caustic substance and has the potential to cause irritation and chemical burns when there is sufficient concentration or duration of contact. The authors present a unique case of a woman who inadvertently received undiluted acetic acid during a routine colposcopy, resulting in significant chemical burns of the vagina, cervix, and perineum. Her burns were treated with topical estrogen cream of 1 g twice daily applied directly to the wounds. The burn wounds were fully healed within 8 weeks without complication or additional treatment. At 6 months after the injury, the patient was allowed to engage in sexual activity, and vaginal dilation and pelvic floor therapy were initiated. At 12 months postinjury, her only symptomatic scarring at the left vaginal wall continues to improve. Thus, topical estrogen treatment of 1 g applied twice daily should be continued until burn scar maturation is complete and treatment improvement plateaus in cases of burns to the vagina, cervix, and perineum. This case is further clinical evidence of estrogen's positive effect on wound healing and its potential role in burn treatment.

    Full Text Available Postmenopausal bleeding (PMB is a discharge that occurs following the firm diagnosis of menopause, which is at least six months from the end of women’s menstrual cycle but not to be confused with infrequent or irregular periods occurring around the time of menopause. It is a common problem representing 5% of all gynecology outpatient attendances which are to eliminate endometrial cancer as the cause of bleed and PMB should be reported urgently to the gynecologist. Uterine bleeding in postmenopausal women is highly indicative clinically of malignancy originating from cervix or endometrium and Human papilloma virus (HPV is one of the causative agent for carcinoma cervix. Incidence of carcinoma cervix increases with the age in mature women, however, incidence of human papillomavirus (HPV infection reduces as menopause sets in. The presence of the virus could be used as an early indication of disease potential. Because the Pap test can only detect clinical evidence of cervical disease, molecular-based diagnostic tools are being used more frequently to detect the virus before abnormal cell growth can be observed. This study was aimed to determine the status of cervical cancer and HPV 16 DNA positivity in relation to postmenopausal bleeding.

A 22-year-old woman with complete müllerian agenesis who underwent a previous surgery for vaginal reconstruction. The live uterine donor was her mother. The uterus transplantation procedure consisted of robot-assisted uterine procurement, orthotopic replacement and fixation of the retrieved uterus, revascularization, and end-to-side anastomoses of bilateral hypogastric arteries and ovarian-uterine vein to the bilateral external iliac arteries and veins. Data from preoperative investigations, surgery, and follow-up (12 months). The duration of the donor and recipient surgeries were 6 and 8 hours, 50 minutes, respectively. No immediate perioperative complications occurred in the recipient or donor. The recipient experienced menarche 40 days after transplant surgery, and she has had 12 menstrual cycles since the surgery. No rejection episodes occurred in the recipient. These results demonstrate the feasibility of live-donor uterine transplantation with a low-dose immunosuppressive protocol and the role of DaVinci robotic assistance during human uterine procurement.

    Arteriovenous malformations (AVM) of the uterus are a rare but potential cause of recurrent pregnancy loss. Only four cases of uterine AVM have resulted in a live birth after conservative management. There is no previous report in which a combination of a müllerian anomaly and an AVM existed concomitantly. A 33-year-old woman with a history of recurrent pregnancy loss was found to have a coexistent uterine AVM and a bicornuate uterus. The patient underwent arterial embolization and Strassman metroplasty and subsequently had a term pregnancy with a live birth. Management of uterine AVM should be individualized, taking into account the patient's desire for future fertility and the stability of her health at presentation.

    We present a case of vaginal ectopic ureter with ipsilateral partial duplication of the upper ureter (Y-type ureter), ipsilateral hypoplastic pelvic kidney and bicornuate uterus in a 20-year-old woman who presented with mild urinary incontinence since infancy. Ultrasonography, computed tomography and intravenous pyelography examination showed a left kidney with no evidence of a right kidney. Cystourethroscopy showed absence of the right hemitrigone. Magnetic resonance (MR) urography demonstrated the presence of a bicornuate uterus, an ectopic dysplastic right kidney in the pelvic cavity, and a right ureter that terminates in the vaginae fornix. The patient underwent right nephroureterectomy and urinary continence was restored completely. Although congenital malformations of the urinary tract are frequently associated with genital tract abnormalities, to best our knowledge, this is the first report of the coexistence of all of these anomalies in an individual. Our report also highlights the importance of MR urography in the diagnosis of such rare and complex anomalies.

    Induction of labour after a previous caesarean section is still controversial. We aim to analyse, in a population of women who have a uterine scar, the maternal, foetal and neonatal complications in relation to the mode of labour and delivery. Retrospective analysis of collected data from all the singleton deliveries of patients with a scarred uterus (N=798), admitted to the hospital between August 2006 and March 2009. maternal and perinatal complications. Among 798 singleton deliveries, 36.1% had a spontaneous labour, 12.6% a prostaglandin-induced labour and 2.9% an ocytocin-induced labour, and 48.4% had an elective caesarean section. The chance of delivering vaginally was respectively 84.4% for those who had a spontaneous labour, 75.2% for those who were induced using prostaglandin, 82.6% after induction using ocytocin. There were eight uterine ruptures, four after spontaneous labour (1.4%), two after prostaglandin induction (2%) and two at the time of an iterative caesarean section (0.5%).

    Arteriovenous malformations (AVMs) of the uterus have various clinical presentations. With the advancement of and accessibility to imaging, the diagnosis of the lesions in association with less severe clinical presentations is becoming more common. Contrary to cases with severe hemorrhage, the management of these cases is not clear. The purpose of this study was to describe our experience with diagnosis, management and long-term follow-up of cases with different clinical presentations of uterine AVMs. The clinical and sonographic presentations of 8 cases diagnosed between July 2000 and July 2003 in our medical center are described. Annual sonographic follow-up was performed for a period of at least 42 months. Only 3 of the 8 cases presented with heavy vaginal bleeding and 2 of them required selective embolization. Two patients had hysterectomy during the study period which was not related to a severe bleeding event. Long-term follow-up for all other cases was significant for sonographic resolution of the uterine AVM. Management of uterine AVMs should be influenced by the clinical and not by the sonographic findings. If clinically feasible, conservative management should be considered as the primary approach, since most of these lesions tend to spontaneously resolve. Copyright 2008 S. Karger AG, Basel.

    1987-06-01

    Sixty-one of 1418 (4.3 per cent) patients treated with radiation for carcinoma of the uterus from 1963 to 1983 had significant radiation-induced complications of the intestine develop which required a surgical opinion considering further management. Ninety-three per cent of these complications involved the rectum. Florid proctitis resolved within two years of onset in 33 per cent of the patients who were managed conservatively while 22 per cent of the patients died of disseminated disease within the same time period. Surgical treatment was eventually necessary in 39 per cent of the patients who were initially treated conservatively for radiation induced proctitis. Rectal excision with coloanal sleeve anastomosis produced a satisfactory result in eight of 11 patients with severe radiation injury involving the rectum. The incidence of radiation-induced and malignant rectovaginal fistula were similar (1 per cent), but disease-induced symptoms tended to occur earlier after primary treatment (a median of eight months) compared with radiation-induced symptoms (a median of 16 months).

  19. Dedifferentiated Leiomyosarcoma of the Uterus with Heterologous Elements: A Potential Diagnostic Pitfall

    Rawish, Kojo R.; Fadare, Oluwole

    2012-01-01

    Dedifferentiation is a phenomenon that is well characterized in a variety of tumors and is defined by the occurrence of a high-grade or undifferentiated tumor, typically unrecognizable regarding its line of differentiation, from a low-grade/borderline neoplasm. This phenomenon has previously been described in 2 uterine leiomyosarcomas, but both were devoid of heterologous elements. The authors describe herein a case of a dedifferentiated leiomyosarcoma of the uterus with osteoid heterologous elements, believed to be the first such reported case. The original tumor was a high-grade leiomyosarcoma with large low-grade and leiomyoma-like areas and whose constituent cells displayed intense nuclear immunoreactivity for both estrogen receptor (ER) and progesterone receptor (PR) in approximately 30% of cells.

    Full Text Available Dedifferentiation is a phenomenon that is well characterized in a variety of tumors and is defined by the occurrence of a high-grade or undifferentiated tumor, typically unrecognizable regarding its line of differentiation, from a low-grade/borderline neoplasm. This phenomenon has previously been described in 2 uterine leiomyosarcomas, but both were devoid of heterologous elements. The authors describe herein a case of a dedifferentiated leiomyosarcoma of the uterus with osteoid heterologous elements, believed to be the first such reported case. The original tumor was a high-grade leiomyosarcoma with large low-grade and leiomyoma-like areas and whose constituent cells displayed intense nuclear immunoreactivity for both estrogen receptor (ER and progesterone receptor (PR in approximately 30% of cells. The tumor recurred six months after its resection as an undifferentiated sarcoma that was negative for smooth muscle markers, but which remained positive for ER and PR. Osteoid production was only identified in the recurrent tumor and was significant in extent therein. This case highlights the immunophenotypic changes that may occur in dedifferentiated leiomyosarcomas, and this possibility should be a consideration when an apparently undifferentiated sarcoma is identified in a patient with a history of uterine leiomyosarcoma. In our case, the expression of ER and PR provided significant supportive evidence of the uterine origin of the recurrent tumor.

    To evaluate the feasibility and safety of office hysteroscopic metroplasty using a 980nm diode laser. 18 patients were treated for septate uterus between 2013 and 2016. The indications for hysteroscopic metroplasty were recurrent abortion in 11 of the women and primary infertility in the other seven. We used a 5mm-office hysteroscope with a diode laser fibre. After exploration of the cavity, the septum was divided with use of the laser fibre. Operating time was 13,16±1,33min. Intraoperative pain was 3,05±0,72. No intraoperative or postoperative complications were observed. Follow-up performed 2 months after the hysteroscopic metroplasty confirmed the complete removal of the septum and no evidence of intrauterine synechiae. Office hysteroscopic metroplasty with use of a diode laser is safe and feasible; we believe that vaporization of the septum with a diode laser could reduce the formation of adhesions and consequently reduce the occurrence of septum persistence.

    It has been suggested that environmental contaminants that mimic the effects of estrogen contribute to disruption of the reproductive systems of animals in the wild, and to the high incidence of hormone-related cancers and diseases in Western populations. Previous studies have shown that functionally, cadmium acts like steroidal estrogens in breast cancer cells as a result of its ability to form a high-affinity complex with the hormone binding domain of the estrogen receptor. The results of the present study show that cadmium also has potent estrogen-like activity in vivo. Exposure to cadmium increased uterine wet weight, promoted growth and development of the mammary glands and induced hormone-regulated genes in ovariectomized animals. In the uterus, the increase in wet weight was accompanied by proliferation of the endometrium and induction of progesterone receptor (PgR) and complement component C3. In the mammary gland, cadmium promoted an increase in the formation of side branches and alveolar buds and the induction of casein, whey acidic protein, PgR and C3. In utero exposure to the metal also mimicked the effects of estrogens. Female offspring experienced an earlier onset of puberty and an increase in the epithelial area and the number of terminal end buds in the mammary gland.

  3. Distribution of versican and hyaluronan in the mouse uterus during decidualization

    Full Text Available Preparation for embryo implantation requires extensive adaptation of the uterine microenvironment. This process consists of cell proliferation and cell differentiation resulting in the transformation of endometrial fibroblasts into a new type of cell called decidual cell. In the present study, we followed the space-time distribution of versican and hyaluronan (HA in different tissues of the uterus before and after embryo implantation. Fragments of mouse uteri obtained on the fourth, fifth, sixth and seventh days of pregnancy were fixed in Methacarn, embedded in Paraplast and cut into 5-µm thick sections. HA was detected using a biotinylated fragment of the proteoglycan aggrecan, which binds to this glycosaminoglycan with high affinity and specificity. Versican was detected by a polyclonal antibody. Both reactions were developed by peroxidase methods. Before embryo implantation, both HA and versican were present in the endometrial stroma. However, after embryo implantation, HA disappeared from the decidual region immediately surrounding the implantation chamber, whereas versican accumulated in the same region. The differences observed in the expression of HA and versican suggest that both molecules may participate in the process of endometrial decidualization and/or embryo implantation.

    We report a case of spontaneous intraperitoneal rupture of the bladder. A 54-year-old woman was admitted to our hospital with the chief complaints of severe lower abdominal pain, dysuria and macroscopic hematuria in October, 1985. In 1969, she had had a radical hysterectomy and postoperative irradiation for cancer of the uterus. Two years later she had undergone additional irradiation. On physical examination, the abdomen was tender with guarding and signs of peritonitis. Laboratory data revealed a blood urea nitrogen of 32.8 mg/dl and all electrolytes were normal. Excretory urogram showed normal upper urinary tract but irregularity of the bladder dome. Cystoscopy revealed acute inflammation of the bladder mucosa. Consequently, we made a presumptive diagnosis of radiation cystitis and she was treated with antibiotics and drip infusion. Within a week her general condition was improved and she had discharged. In June, 1986 she was admitted again with the same chief complaints as at her first admission. Cystoscopic findings showed a hole on the postero-superior wall and retrograde cystogram revealed an intraperitoneal rupture of the bladder. At exploration a necrotic bladder wall resected and closed in 3 layers. The post operative course was uneventful.

    Premature labour (PTL) is the single most significant factor contributing to neonatal morbidity in Europe with enormous attendant healthcare and social costs. Consequently, it remains a major challenge to alleviate the cause and impact of this condition. Our ability to improve the diagnosis and treatment of women most at risk of PTL is, however, actually hampered by an incomplete understanding of the ways in which the functions of the uterine myocyte are integrated to effect an appropriate biological response at the multicellular whole organ system. The level of organization required to co-ordinate labouring uterine contractile effort in time and space can be considered immense. There is a multitude of what might be considered mini-systems involved, each with their own regulatory feedback cycles, yet they each, in turn, will influence the behaviour of a related system. These include, but are not exclusive to, gestational-dependent regulation of transcription, translation, post-translational modifications, intracellular signaling dynamics, cell morphology, intercellular communication and tissue level morphology. We propose that in order to comprehend how these mini-systems integrate to facilitate uterine contraction during labour (preterm or term) we must, in concert with biological experimentation, construct detailed mathematical descriptions of our findings. This serves three purposes: firstly, providing a quantitative description of series of complex observations; secondly, proferring a database platform that informs further testable experimentation; thirdly, advancing towards the establishment of a virtual physiological uterus and in silico clinical diagnosis and treatment of PTL.

    Uteroferrin is a purple iron-containing acid phosphatase secreted by the porcine uterus under the influence of the hormone, progesterone. It is synthesized by the glandular epithelial cells of the uterine endometrium and during pregnancy is taken up by specialized structures (areolae) opposite each uterine gland. Uteroferrin is then released into the fetal circulation and cleared by the liver or fetal kidney. A major role in iron transport to the fetus has been proposed. Uteroferrin, as purified from uterine secretions of pigs, possesses mainly high mannose (predominantly Man5 and Man6) chains. These oligosaccharide chains of uteroferrin appear to be responsible for its binding and uptake by reticuloendothelial cells of the fetal liver which is the major site of erythropoiesis of the fetus. Uteroferrin, although implicated in transplantal iron transport, also possesses many of the properties of a lysosomal enzyme and, when newly synthesized, carries the so-called lysosomal recognition marker, mannose 6-phosphate. The phosphate group is masked by a covering N-acetylglucosamine residue, a feature which may account for its secretion rather than retention within lysosomes. Evidence is also presented that the oligosaccharide chains of newly synthesized uteroferrin are larger than those of the mature form and are trimmed after secretion. The phosphate group is also removed. It is not clear whether uteroferrin carbohydrate is implicated in the movement of the glycoprotein across the placenta as well as its uptake by the fetal liver.

    Four myxoid variant of uterine mesenchymal tumors are reported. One was a low grade stromal sarcoma with infiltrative margins and the others were well circumscribed tumors corresponding to an endometrial stromal nodule and two leiomyomas. They were hypocellular neoplasms composed of stellated cells with an abundant Alcian Blue positive myxoid matrix. The myxoid nature of the neoplasms obscured their cellular nature and made the distinction between smooth muscle and endometrial stromal tumors difficult. Endometrial stromal tumors, showed very focal areas of small basophilic cells, characteristic of endometrial stroma. The diagnosis was based on the presence of a spiral arteriolar network, a CD10 positivity as well as the absence of h-caldesmon and desmin expression. The two myxoid leiomyomas showed more spindle cells and a desmin expression while h-caldesmon was negative and CD10 focally positive in both cases. Myxoid variant of endometrial stromal tumors does not necessarily exhibit the typical morphology of endometrial stroma. They may demonstrate morphological features of smooth muscle tumors in the uterus. Also, myxoid changes in uterin smooth muscle tumors may modify the classical immunoreactivity of smooth muscle markers in these tumors and make it difficult to distinguish between benign and malignant neoplasms. An immunohistochemical panel of antibodies including CD10, h-caldesmon and desmin may help in establishing the correct diagnosis. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

    The uterus of an oviparous gecko, Hemidactylus turcicus, was analysed after ovariectomized females underwent a period of treatment (up to 14 days) with exogenous estradiol. Analysis focused on the uterine mucosa, which is made up of an epithelial layer and an underlying lamina propria containing the shell glands. These tissues are thought to be responsible for secretion of the eggshell components and were thus chosen for analysis using transmission electron microscopy. In ovariectomized females, the epithelial layer was low and cuboidal with minimal/no differentiation or secretory activity. Treatment with exogenous estradiol resulted in a significant increase in cell height associated with gradual differentiation of the epithelium. Development of non-ciliated cells included production of secretory granules (low electron density) at the apical cell surface. The shell glands showed less obvious changes over the course of treatment. Shell glands contained two cell types: dark cells with darkly staining nuclei and organelles, and light cells with very indistinct nuclei and organelles, except for prominent rough endoplasmic reticulum and free ribosomes. This study provides results consistent with published light microscopy studies for other reptiles and additionally provides ultrastructural details of reptilian uterine development not previously available.

  9. Angular ectopic pregnancy presenting as rupture of lateral wall of the uterus

    2008-01-01

    Full Text Available This is a case report of a 32-year-old woman, being treated for secondary infertility, with history of previous ectopic pregnancy, who presented to the emergency obstetrical room in a state of hypovolemic shock. A diagnosis of ruptured ectopic pregnancy was confirmed in view of history of 14 weeks amenorrhea with a positive urine pregnancy test and positive colpopunture. She was immediately shifted for an emergency exploratory laparotomy. Intraoperatively, the authors were surprised to encounter a right lateral wall rupture uterus and ~14 weeks foetus with the placenta lying freely in the peritoneal cavity. That was suggestive of a right interstitial ectopic which had grown up to 14 weeks, invaded the uterine cavity thus forming an angular ectopic, which ended up as the catastrophic event. The authors here wish to highlight that angular pregnancy is rare but it has catastrophic consequences including maternal mortality. Had the patient presented early, in view of history of previous ectopic, an ultrasonography and color Doppler would have been useful in early detection. And a fertility conserving management in the form of Methotrexate therapy or Selective Uterine artery embolization could have been done.

    Uterine quiescence at the time of embryo transfer is a prerequisite for successful in vitro fertilization (IVF). This study assessed whether prostaglandin-induced contractions in the perfused swine uterus can be reduced by progesterone. Fifty-eight non-pregnant swine uteri were perfused using an established extracorporeal perfusion model. Intrauterine pressure changes during perfusion with prostaglandin (PG) administration (PGE1, PGE2, PGF2α) and progesterone (1 pg/ml, 10 pg/ml, 25 pg/ml, 50 pg/ml) were assessed using an intrauterine double-chip microcatheter. The contraction-stimulating effect of PGs was clearly reduced by progesterone. Only PGE1 still triggered relevant contractions during continuous perfusion with progesterone solution, up to a concentration of 10 pg/ml. With PGE2 and PGF2α, a clear reduction of uterine contractility was observed even at at a progesterone concentration of 1 pg/ml. The extracorporal perfusion model of swine uteri shows that PG-induced contractions can be reduced in a dose-dependent manner by progesterone.

  14. Male Seminal Relaxin Contributes to Induction of the Post-mating Cytokine Response in the Female Mouse Uterus

    Directory of Open Access Journals (Sweden)

    Danielle J. Glynn

    2017-06-01

    Full Text Available The hormone relaxin is important in female reproduction for embryo implantation, cardiovascular function, and during labor and lactation. Relaxin is also synthesized in males by organs of the male tract. We hypothesized that relaxin might be one component of seminal plasma responsible for eliciting the female cytokine response induced in the uterus at mating. When recombinant relaxin was injected into the uterus of wild-type (Rln+/+ mice at estrus, it evoked the production of Cxcl1 mRNA and its secreted protein product CXCL1 in four of eight animals. Mating experiments were then conducted using mice with a null mutation in the relaxin gene (Rln−/− mice. qRT-PCR analysis of mRNA expression in wild-type females showed diminished uterine expression of several cytokine and chemokine genes in the absence of male relaxin. Similar differences were also noted comparing Rln−/− and Rln+/+ females mated to wild-type males. Quantification of uterine luminal fluid cytokine content confirmed that male relaxin provokes the production of CXCL10 and CSF3 in Rln+/+ females. Differences were also seen comparing Rln−/− and Rln+/+ females mated with Rln−/− males for CXCL1, CSF3, and CCL5, implying that endogenous relaxin in females might prime the uterus to respond appropriately to seminal fluid at coitus. Finally, pan-leukocyte CD45 mRNA was increased in wild-type matings compared to other combinations, implying that male and female relaxin may trigger leukocyte expansion in the uterus. We conclude that male and/or female relaxin may be important in activating the uterine cytokine/chemokine network required to initiate maternal immune adaptation to pregnancy.

  15. Role of progesterone and estrogen in the preparation of the uterus and induction of implantation in the mouse

    Huet-Hudson, Y.M.

    1989-01-01

    The implantation of the embryo into the uterine wall and subsequent decidualization of the uterine endometrium requires ovarian progesterone and estrogen. Prerequisites for implantation include (1) the preparation of the uterus for embryo implantation and (2) increase stromal capillary permeability at the site of embryo attachment. During the first three days of pregnancy, epithelial cells undergo proliferation, death and differentiation, in response to preovaluatory estrogen. These events occur in stromal cells in response to progesterone on days 4 and 5. The mechanism by which the steroid hormones modulate their functions and how estrogen initiates implantation in a progesterone-primed (P{sub 4}) uterus in not clearly understood. The author shows that 24h of P{sub 4}-priming is adequate for induction of implantation in the mouse. In addition, following this initial exposure of the uterus to P{sub 4} a long lasting effect is induced i.e. 24h of priming is no longer required for the induction of implantation. The uterine cell proliferation and differentiation that occurs in response to steroid hormones could be through their modulation of the expression of proto-oncogenes and growth factors. Results show that the proto-oncogene, c-myc and the growth factor, EGF are expressed in a cell-type specific manner in the uterus and are regulated by P{sub 4} and estrogen in a spatial and temporal manner during early pregnancy. It is apparent that c-myc protein in epithelia is primarily regulated by estrogen, while in the stroma by P{sub 4}. {sup 3}H-thymidine incorporation in specific uterine cell-types correlated with expression of the c-myc protein. On the other hand, EGF is always localized to the epithelia and is primarily regulated by estrogen.

    Willian Augusto de Melo

    Full Text Available Abstract Objectives: to identify factors associated with abnormal cytopathological test uterine cervix. Methods: it is a analytical study with the participation of 390 women who presented abnormal cytopathological from a city in the state of Paraná in 2012. They were randomly selected through sampling plan. Sociodemographic information such as age, marital status, education level and ethnicity were considered independent variables while the high or low-grade cytological lesions as dependent variable. We analyzed the data statistically by Yates Corrected test, Fisher exact test and measures of association by odds ratio. For all analyzes was considered significance level of 5% and 95% confidence interval. Results: the mean age was 38.8 years, 72.9% were married or common-law marriage, 49.7% with low education level and 87.4% race/color white. HPV contamination was detected in 49.7% of women and high-grade cytological lesions in 18.2%. The low educa-tional level (95%OR=4.07 and non-white ethnicity (95%OR=2.22 were strongly associated with the development to cervical lesions (p<0.05. Conclusions: sociodemoghaphic characteristics were crucial to high-risk lesions and development of cervical cancer, especially in women with low educational level and race/color black or brown. These results confirm the persistence of diseases related to preventable and avoidable causes in the country.

    Early detection through screening plays a major role in reducing the impact of cervical cancer on patients. When detected before the invasive stage, precancerous lesions can be eliminated with very limited surgery. Polarimetric imaging is a potential alternative to the standard screening methods currently used. In a previous proof-of-concept study, significant contrasts have been found in polarimetric images acquired for healthy and precancerous regions of excised cervical tissue. To quantify the ability of the technique to differentiate between healthy and precancerous tissue, polarimetric images of seventeen cervical conization specimens (cone-shaped or cylindrical wedges from the uterine cervix) are compared with results from histopathological diagnoses, which is considered to be the "gold standard." The sensitivity and specificity of the technique are calculated for images acquired at wavelengths of 450, 550, and 600 nm, aiming to differentiate between high-grade cervical intraepithelial neoplasia (CIN 2-3) and healthy squamous epithelium. To do so, a sliding threshold for the scalar retardance parameter was used for the sample zones, as labeled after histological diagnosis. An optimized value of ˜83% is achieved for both sensitivity and specificity for images acquired at 450 nm and for a threshold scalar retardance value of 10.6 deg. This study paves the way for an application of polarimetry in the clinic.

    The aim of this study was to quantify the impact of different types and magnitudes of dosimetric uncertainties in cervix cancer brachytherapy (BT) on tumour control probability (TCP) and normal tissue complication probability (NTCP) curves. A dose-response simulation study was based on systematic and random dose uncertainties and TCP/NTCP models for CTV and rectum. Large patient cohorts were simulated assuming different levels of dosimetric uncertainties. TCP and NTCP were computed, based on the planned doses, the simulated dose uncertainty, and an underlying TCP/NTCP model. Systematic uncertainties of 3-20% and random uncertainties with a 5-30% standard deviation per BT fraction were analysed. Systematic dose uncertainties of 5% lead to a 1% decrease/increase of TCP/NTCP, while random uncertainties of 10% had negligible impact on the dose-response curve at clinically relevant dose levels for target and OAR. Random OAR dose uncertainties of 30% resulted in an NTCP increase of 3-4% for planned doses of 70-80Gy EQD2. TCP is robust to dosimetric uncertainties when dose prescription is in the more flat region of the dose-response curve at doses >75Gy. For OARs, improved clinical outcome is expected by reduction of uncertainties via sophisticated dose delivery and treatment verification. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    2012-03-01

    Full Text Available Abstract Background Cervical uterine epithelial cells maintain a physiological and pathogen-free milieu in the female mammalian reproductive tract and are involved in sperm-epithelium interaction. Easily accessible, differentiated model systems of the cervical epithelium are not yet available to elucidate the underlying molecular mechanisms within these highly specialized cells. Therefore, the aim of the study was to establish a cell culture of the porcine cervical epithelium representing in vivo-like properties of the tissue. Results We tested different isolation methods and culture conditions and validated purity of the cultured cells by immunohistochemistry against keratins. We could reproducibly culture pure epithelial cells from cervical tissue explants. Based on a morphology score and the WST-1 Proliferation Assay, we optimized the growth medium composition. Primary porcine cervical cells performed best in conditioned Ham's F-12, containing 10% FCS, EGF and insulin. After cultivation in an air-liquid interface for three weeks, the cells showed a discontinuously multilayered phenotype. Finally, differentiation was validated via immunohistochemistry against beta catenin. Mucopolysaccharide production could be shown via alcian blue staining. Conclusions We provide the first suitable protocol to establish a differentiated porcine epithelial model of the cervix uteri, based on easily accessible cells using slaughterhouse material.

    Rationale: The tumor microenvironment (TME) is heterogeneous including both malignant and host cell components as well as regions of hypoxia, elevated interstitial fluid pressure (IFP) and poor nutrient supply. The quantitative extent to which the microenvironmental properties of primary tumors are recapitulated in xenograft models is not well characterized. Methods: Xenografts were generated by implanting tumor biopsies directly into the cervix of mice to create a panel of orthotopically-passaged xenografts (OCICx). Tumors were grown to ~1 cm (diameter) and IFP measurements recorded prior to sacrifice. Enlarged para-aortic lymph nodes (>1–2 mm) were excised for histologic confirmation of metastatic disease. Quantitative histological analysis was used to evaluate hypoxia, proliferation, lymphatic and blood vessels in the epithelial and stromal regions of the xenografts and original patient tumour. Results: IFP and nodal disease were not correlated with tumor engraftment. IFP measurements in the xenografts were generally lower than those in the patient’s tumor. Lymphatic metastasis increased with passage number as did levels of hypoxia in the epithelial component of the xenografts. The blood vessel density in the stromal component of the xenografts increased in parallel. When all the markers were compared between the biopsy and the respective 3rd generation xenograft 10 of 11 tumors showed a good correlation. Conclusions: This ongoing study provides characterization about tumoral and stromal heterogeneity in a unique orthotopic xenograft model.

    From November, 1975 to December, 1985, 170 patients with carcinoma of the uterine cervix underwent bipedal lymphography prior to treatment. Seventy one of them, who were mainly at Stage II, underwent radical hysterectomy with pelvic lymphadenectomy. In 30 of the 71 cases, lymph node metastases were detected. The main lymphographic findings of the positive cases were filling defect, stasis and oozing of the contrast medium, which were found in 53 %, 60 % and 33 % of the cases, respectively. A correlation was observed between the filling defect and stasis. No patient had matastasis and negative findings. Of the remaining 41 patients without metastasis, lymphograms were negative in 78 %. In 99 patients, who did not undergo surgery, the percentage of positive lymphographic findings increased significantly with progress of clinical stage. In Stage IV disease (29 cases), blockade of lymphatics (25 %), lymphatico-venous anastomosis, lymphocyst, collateral and reflux, as well as filling defect (48 %), stasis (31 %) and oozing (31 %), were seen. Lymphography in cervical carcinoma may be useful for examining lymph node metastasis.

    The Chilean Ministry of Health announced the incorporation of a human papillomavirus (HPV) vaccine to prevent cervix uterine cancer (CUC) into the national immunization program during year 2014 This decision was adopted despite of two opposing documents and a significant decrease in cervical cancer associated mortality due to cytological cervical screening. The burden of disease attributed to CUC has declined in Chile and current cost-effectiveness studies should be reviewed considering this decreasing trend, the progressive decrease in coverage rates observed during the past years, the potential need for aditional doses and lower vaccine costs if vaccine is acquired through the PAHO revolving fund. Moreover, serious adverse events associated with these vaccines, which in some countries are more frequent than CUC associated mortality, have not been thoroughly evaluated and are probably underreported. The decision to incorporate the vaccine occurs in a context of progressive weakening of the national cervical screening program leading to a reduced population coverage. This situation jepeordizes the achievements already obtained and poses a challenge to vaccine introduction considering that not all the high-risk viral subtypes are included and thus the risk for CUC does not disappear making cervical screening a vital component of the program that needs to be maintained. This governmental resolution requires a more solid scientific foundation and should not be implemented without resolving current cervical screening shortcomings.

    Background: Premalignant and malignant lesions are not uncommon in Pakistani women, especially in the older age-groups Aim: This study was conducted to determine the clinicopathological importance of conventional Papanicolaou (Pap) smears for the diagnosis of premalignant and malignant lesions of the cervix. Materials and Methods: Pap smears of 1000 women were examined from January 2007 to June 2009. Only cases with neoplastic cytology were included. Results: The overall frequency of normal, inadequate, neoplastic, and infective smears was 50%, 1.8%, 10.2%, and 38.3%, respectively. Most of the patients (67%) were in the postmenopausal age-group, with the mean age being 44.7±15.63 years. The commonest clinical signs/symptoms seen among the 102 patients with neoplastic gynecological lesions were vaginal discharge and abnormal bleeding (93/102;(91.2% and 62/102;60.7%). Of the 102 cases with neoplastic lesions 46 patients (45%) had low-grade squamous cell intraepithelial lesions (LSILs), 22 (21.5%) had high-grade squamous cell intraepithelial lesions (HSILs), 14 (13.7%) had squamous cell carcinoma, and 6 (5.8%) showed features of adenocarcinoma. Ten (9.8%) cases showed cytology of atypical squamous cells of undetermined significance (ASCUS) and four (3.9%) cases had atypical glandular cells of undetermined significance (AGUS). Conclusion: We conclude that cervical smear examination is well suited for diagnosing neoplastic disease. It is clear that cervical neoplastic lesions are becoming a problem in Pakistan.

    Full Text Available A study was done in 75 patients who underwent induction of labour with Prostaglandin E2 gel. All these patients had an unripe cervix. The commonest indications were post-datism, intrauterine growth retardation and pregnancy-induced hypertension. All patients were primigravidas with singleton pregnancy and beyond 35 weeks of pregnancy. The mean Bishop score at the time of instillation was less than three. The improvement of another 2-3 points within six hours and by 7-8 points within 12 hours was found after instillation of the gel. 92% of the patients went into spontaneous labour and 8% required reinstillation. The incidence of failed induction was 1.33%. The mean duration of latent phase was 10.34 hours. Induction delivery time was 16.43 hours. 68.1% patients required augmentation of labour and 31.9% did not require augmentation of labour with oxytocin drip. The incidence of vaginal delivery was 81.33% and that of caesarean section was 17.33%. The commonest indication of caesarean section was foetal distress.

    Full Text Available Cervical cancer is one of the leading gynaecological malignancies worldwide. It is an infectious disease of the cervix, associated with human papillomavirus infection (HPV, infection with bacterial agents such as Chlamydia trachomatis and Neisseria gonorrhoea as well as human immunodeficiency virus (HIV. Furthermore, it is an AIDS-defining disease with an accelerated mortality in HIV-infected women with cervical cancer. With the introduction of robust vaccination strategies against HPV in the developed world, it is anticipated that the incidence of cervical cancer will decrease in the coming years. However, vaccination has limited benefit for women already infected with high-risk HPV, and alternative therapeutic intervention strategies are needed for these women. Many pathological disorders, including cervical cancer, are characterised by the exacerbated activation and maintenance of inflammatory pathways which are considered to be regulated by infectious agents. In cervical cancer, hyperactivation of these inflammatory pathways and regulation of immune infiltrate into tissues can potentially play a role not only in tumorigenesis but also in HIV infection. In this paper we will discuss the contribution of inflammatory pathways to cervical cancer progression and HIV infection and the role of HIV in cervical cancer progression.

    Until the 1970s the irradiated region of a patient undergoing external beam radiotherapy was considered a homogeneous volume and a regular surface, with physical characteristics similar to water. With the improvement of medical imaging equipment, it has become possible to conduct planning in radiotherapy treatment that considers the heterogeneities and irregularities of a patient's anatomy. Consequently, such technological resources have brought greater accuracy to radiotherapy. In this study, we determined the variation in the average amount of absorbed dose on the target volume and at the point of prescription treatment by comparing the doses which were calculated in a planning system considering the patient both as a homogeneous, and as a heterogeneous medium. The results showed that when we take into account the volume of the upper vagina and cervix, and consider the pelvis as a heterogeneous medium, the calculated dose was under-estimated at some points in the studied volume with respect to the dose when this region was considered homogeneous.

    Full Text Available Abstract Background Septate uterus, one of the most common forms of congenital uterine malformations, negatively affects female reproductive health. Methods In a retrospective cohort study, we evaluated the reproductive outcome after hysteroscopic septoplasty in 64 women with septate uterus and primary or secondary infertility. We performed a systematic review of studies evaluating the reproductive outcome after hysteroscopic septoplasty. Results Sixty-four women underwent hysteroscopic septoplasty. In 2/64 (3% women, intraoperative uterine perforation occurred. Complete follow-up was available for 49/64 (76% patients. Mean follow-up time was 68.6 +/- 5.2 months. The overall pregnancy rate after hysteroscopic septoplasty was 69% (34/49. The overall life birth rate (LBR was 49% (24/49. The mean time interval between surgery and the first life birth was 35.8 +/- 22.5 months. Including our own data, we identified 18 studies investigating the effect of septoplasty on reproductive outcome in 1501 women. A pooled analysis demonstrated that hysteroscopic septoplasty resulted in an overall pregnancy rate of 60% (892/1501 and a LBR of 45% (686/1501. The overall rate of intra- and postoperative complications was 1.7% (23/1324 and the overall rate of re-hysteroscopy was 6% (79/1324. Conclusions In women with septate uterus and a history of infertility, hysteroscopic septoplasty is a safe and effective procedure resulting in a pregnancy rate of 60% and a LBR of 45%.

    Rhinopoma hardwickei hardwickei has an annual reproductive cycle. Although many of the females become inseminated from the latter half of February until about the middle of April, ovulation has not been recorded until the 11th of March. A single follicle reached full development and released one ovum from either of the ovaries with nearly equal frequency, and a single conceptus was carried in the ipsilateral uterine cornu during each cycle. The embryo descended into the uterus as an early morula and attained the bilaminar blastocyst stage before undergoing implantation. As the morula advanced in age, the embryonic surface of the zona became progressively more basophilic. Hence in advanced morulae, the inner surface of the zona pellucida took a dark stain with hematoxylin and appeared like a distinct thin membrane, while the rest of the thickness of the zona was eosinophilic. Although progestational changes commenced in both uterine cornua, they became augmented in the uterine cornu on the side of ovulation and blastocyst attachment. After blastocyst attachment, the contralateral cornu reverted to an anestrus condition. The progestational changes became less conspicuous from the cranial to the caudal end of the uterus. Evidently, there was a linear gradient in the progestational response of the uterus with the cranial end being most responsive and the caudal end least responsive. The precise mechanism which brings this about is not known.

    β(3)-adrenoceptor is a potential target for uterine relaxant drugs for the treatment of preterm labor. Mouse is an ideal experimental model for preterm labor. However, there is limited information on the molecular and functional characteristics of β(3)-adrenoceptors in mouse uterus. Therefore, the current study was undertaken to characterize the β(3)-adrenoceptors in late pregnant mouse uterus by molecular and functional experiments and to compare their expression and function with the β(2)-adrenoceptors. Using RT-PCR, we demonstrated the presence of β(3)-adrenoceptor mRNA in the mouse uterus. Accordingly, selective β(3)-adrenoceptor agonist SAR150640 (ethyl-4-{trans-4-[((2S)-2-hydroxy-3-{4-hydroxy-3[(methylsulfonyl)amino]-phenoxy}propyl)amino]cyclohexyl}benzoate hydrochloride) caused concentration-dependent relaxation of the isolated tissue. SR59230A (1 μM), a selective antagonist of β(3)-adrenoceptors, antagonized the relaxant response to SAR150640. Using real-time PCR we found that in comparison to β(3)-adrenoceptor mRNA, β(2)-adrenoceptor mRNA is predominantly expressed in the late pregnant mouse uterus. We then assessed the comparative efficiency of different β-adrenoceptor agonists, such as SAR150640, salbutamol and isoprenaline to relax the tissue. SAR150640 (pD(2) 6.64±0.21, E(max) 104.9±7.95), salbutamol (pD(2) 8.57±0.062, E(max) 103.1±3.22) and isoprenaline (pD(2) 9.48±0.084, E(max) 102.9±5.18) caused concentration-dependent inhibition of uterine rhythmic contractions. While the maximal relaxation to these agonists was comparable, the order of potency was isoprenaline>salbutamol>SAR. These results suggest that β(3)-adrenoceptor mRNA is present in the pregnant mouse uterus and is functionally active. The predominance of β(2)- over β(3)-adrenoceptor expression may explain variable potency amongst the β-adrenoceptor agonists. Copyright © 2012 Elsevier B.V. All rights reserved.

    Embryonic diapause (delayed implantation) is a reproductive strategy widespread in the animal kingdom. Under this condition, embryos at the blastocyst stage become dormant simultaneously with uterine quiescence until environmental or physiological conditions are favorable for the survival of the mother and newborn. Under favorable conditions, activation of the blastocyst and uterus ensues with implantation and progression of pregnancy. Although endocrine factors are known to participate in this process, the underlying molecular mechanism coordinating this phenomenon is not clearly understood. We recently found that uterine muscle segment homeobox (Msx) transcription factors are critical for the initiation and maintenance of delayed implantation in mice. To better understand why Msx genes are critical for delayed implantation, we compared uterine proteomics profiles between littermate floxed (Msx1/Msx2f/f) mice and mice with uterine deletion of Msx genes (Msx1/Msx2d/d) under delayed conditions. In Msx1/Msx2d/d uteri, pathways including protein translation, ubiquitin-proteasome system, inflammation, chaperone-mediated protein folding, and endoplasmic reticulum (ER) stress were enriched, and computational modeling showed intersection of these pathways on inflammatory responses. Indeed, increases in the ubiquitin-proteasome system and inflammation conformed to proteotoxic and ER stress in Msx1/Msx2d/d uteri under delayed conditions. Interestingly, treatment with a proteasome inhibitor bortezomib further exacerbated ER stress in Msx1/Msx2d/d uteri with aggravated inflammatory response, deteriorating rate of blastocyst recovery and failure to sustain delayed implantation. This study highlights a previously unrecognized role for Msx in preventing proteotoxic stress and inflammatory responses to coordinate embryo dormancy and uterine quiescence during embryonic diapause.

    Full Text Available The microbial population represents a group of heterogeneous germs comprising several different species which live and act together in the same place. The communities of micro-organisms, as independent population groups, are better adapted for growing than a unique species. The microbial flora of the puerperal uterus differs from case to case, being represented both as bacteria admitted as pathogenic and particular tropism for the uterine morphological structures and opportunist bacteria which are quite numerous. Here are some of the microbial identified species: Streptococcus spp., E.coli, C.pyogenes . These exercise the pathogenic action under certain circumstances such as: the existence of these germs in big quantities, virulence and the high rate of pathogenity, the low resistence of the body. The experimental and epidemiological observations have proved the fact that autochthonous microorganisms (the normal, permanent microflora, adapted to develop in certain natural habitats, exercise a barrier function which protects the animal organisms from the implantation of several microorganisms which penetrate in the outer environment. The necrotic processes at the level of the uterine mucous membrane were at different stages of evolution in all the cases in question with big or even huge differences from one geographical area to another one. In some geographical areas the alternative processes were obvious only at the surface of the mucous membrane, with the affecting of the cells and area placed close under the basic membrane, while the epithelium although it seemed obviously affected, was not detached from the basic membrane. The cells of the uterine mucous membrane seemed detached here and there either under the form of groups taking up small areas, or in big areas alternating with zones where the epithelium was still partially preserved and, eventually extensive areas, completely without mucuos membrane, where even traits of cells at the level

    We previously reported that vascular endothelial growth factor induced vascular endothelial (VE)-cadherin tyrosine phosphorylation at Y685 in a Src-dependent manner in vitro. Here, we studied the occurrence of Y685 phosphorylation in vivo in the female reproductive tract because it is a unique model of physiological vascular remodeling dependent on vascular endothelial growth factor. We first developed and characterized an anti-phospho-specific antibody against the site Y685 of VE-cadherin to monitor VE-cadherin phosphorylation along the four phases of mouse estrous cycle, termed proestrus, estrus, metestrus, and diestrus. A dynamic profile of tyrosine phosphorylated proteins was observed in both uterus and ovary throughout mouse estrous cycle, including kinase Src, which was found highly active at the estrus phase. The extent of tyrosine phosphorylated VE-cadherin was low at proestrus but strongly increased at estrus and returned to baseline at metestrus and diestrus, suggesting a potent hormonal regulation of this specific process. Indeed, C57Bl/6 female mice treatment with pregnant mare serum gonadotropin and human chorionic gonadotropin confirmed a significant increase in phosphoY685-VE-cadherin compared with that in untreated mice. These results demonstrate that VE-cadherin tyrosine phosphorylation at Y685 is a physiological and hormonally regulated process in female reproductive organs. In addition, this process was concomitant with the early steps of vascular remodeling taking place at estrus stage, suggesting that phosphoY685-VE-cadherin is a biomarker of endothelial cell activation in vivo.

    The uterine organization in Tetrabothrius erostris (Tetrabothriidea) was investigated by the methods of transmission and scanning electron microscopy. In sexually mature proglottids, the uterine wall consists of a syncytial epithelium (1.4-2.5 μm thick, except in regions containing nuclei). The ribosomes, mitochondria and numerous cisternae of granular endoplasmic reticulum with concentric or parallel profiles with electron lucent material are observed in the epithelium. The uterine wall is characterized by the abundance of lipid droplets that are localized inside the long protrusions of the uterine epithelium (called fungiform papillae) up to 15-17 μm and in the surrounding medullary parenchyma. The protrusions with lipid droplets in the proximal ends of the uterus are located closely to each other. A basal matrix (up to 0.6 μm thick) supports the uterine epithelium. The musculature consisting of 1-2 muscle layers is well developed; large myocytons are connected with the myofibrils and have a nucleus that reaches 4 μm in size. In gravid proglottids, the epithelium without nuclei is reduced to 0.2-1.6 μm thick. The number of protrusions of the uterine epithelium and lipid droplets in the epithelial layer decreases. Sparse small muscle bundles underlay the uterine wall at this stage; the basal matrix is feebly marked. The matrotrophy or the support by nutrition from the parent organism to embryos is discussed for T. erostris which belongs to oligolecital cestodes and possesses numerous lipid droplets in the uterine wall during the development of embryos.

    Purpose: The aim of the current study was to evaluate the efficacy of uterine artery embolization (UAE) in the management of diffuse uterine leiomyomatosis with mid-term follow-up. Materials and methods: All patients who underwent UAE between 2008 and 2010 for symptomatic fibroids were analyzed. Among 360 cases, a total of 7 patients with diffuse uterine leiomyomatosis diagnosed based on MRI were included in this retrospective study. Patient ages ranged from 29 to 38 (mean 32.7) years. The median follow-up period was 16 (range; 6–31) months. The embolic agent was non-spherical polyvinyl alcohol particles. All patients underwent follow-up MRI at 3 months after UAE. Uterine volumes were calculated using MRI. Menorrhagia symptom changes were assessed at mid-term follow-up. Results: There were no technical failures to catheterize the uterine artery and no adverse events requiring therapy after UAE. Contrast-enhanced MRI showed complete necrosis of the leiomyomatous nodules in 5 patients (71%) 3 months after embolization. Two patients (28%) showed mostly leiomyomatous nodules that were necrotized, some of which were still viable. All 7 patients with menorrhagia had improvement of symptoms at the mid-term follow-up. The initial mean uterine volume was 601.30 ± 533.92 cm{sup 3} and was decreased to a mean of 278.81 ± 202.70 cm{sup 3} at 3 months follow-up, for a mean uterus volume reduction rate of 50.1% (p < 0.05). One patient became pregnant 5 months after UAE treatment. Conclusion: UAE was a highly effective treatment for diffuse uterine leiomyomatosis with mid-term durability and may be a valuable alternative to hysterectomy.

    BACKGROUND AND PURPOSE Uterine spontaneous contraction and pacemaking are poorly understood. This study investigates the role of the mitochondrial Ca2+ store in uterine activity. EXPERIMENTAL APPROACH We investigated the effects of mitochondrial and sarco-endoplasmic reticulum (SER) inhibitors on contraction, membrane potential (Vm) and cytosolic Ca2+ concentration ([Ca2+]c) in longitudinal smooth muscle of the mouse uterus. KEY RESULTS The mitochondrial agents rotenone, carbonylcyanide-3-chlorophenylhydrazone (CCCP), 7-chloro-5-(2-chlorophenyl)-1,5-dihydro-4,1-benzothiazepin-2(3H)-one (CGP37157) and kaempferol decreased the force of contractions. The ATP synthase inhibitor oligomycin had no significant effect. The effects of these agents were compared with those of SER inhibitors cyclopiazonic acid (CPA), 2-amino ethoxyphenylborate (2-APB) and caffeine. All agents, except CPA and oligomycin, decreased contractile force. CPA and CCCP transiently increased contraction frequency, which returned to control levels, whereas rotenone, CGP37157, kaempferol and 2-APB decreased frequency and caffeine had no significant effect. Application of the mitochondrial agents when CPA functionally inhibited stores did not change contraction frequency but, with the exception of kaempferol, decreased force. CCCP caused depolarization and maintained increase in [Ca2+]c or depolarization/transient hyperpolarization and transient increase in [Ca2+]c for oestrus and di-oestrus tissues respectively. Rotenone caused hyperpolarization and maintained increase in [Ca2+]c. CGP37157 and kaempferol caused hyperpolarization but no measurable change in [Ca2+]c. Application of a range of K+ channel blockers indicated a role of Ca2+-activated K+ (KCa) channels in the CCCP- and CGP37157-induced actions. CONCLUSIONS AND IMPLICATIONS Mitochondria have a modulatory role on uterine contractions, with mitochondrial inhibition reducing contraction amplitude and pacemaker frequency by changes in Vm, [Ca2+]c

    This paper presents a summary of the evidence review group (ERG) report into the clinical effectiveness and cost-effectiveness of topotecan in combination with cisplatin for the treatment of recurrent and stage IVB carcinoma of the cervix, in accordance with the licensed indication, based upon the evidence submission from the manufacturer to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal (STA) process. The outcomes measured were overall survival, progression-free survival, response rates, adverse effects of treatment, health-related quality of life (HRQoL) and quality-adjusted life-years (QALYs) gained. The manufacturer stated that topotecan plus cisplatin is the only combination regimen to date to have demonstrated a statistically significant survival advantage compared to cisplatin monotherapy in the licensed population. The clinical evidence came from three clinical trials comparing topotecan plus cisplatin with cisplatin monotherapy (GOG-0179), topotecan plus cisplatin with paclitaxel plus cisplatin (GOG-0169), and four cisplatin-based combination therapies: topotecan plus cisplatin, paclitaxel plus cisplatin, gemcitabine plus cisplatin, and vinorelbine plus cisplatin (GOG-0204). Results from GOG-0179 showed greater median overall survival with topotecan plus cisplatin than with cisplatin monotherapy: 9.4 months versus 6.5 months. Similar results were also reported for median progression-free survival. Response rates also showed an advantage with topotecan plus cisplatin compared with cisplatin monotherapy. The response rates in patients receiving cisplatin monotherapy were very low, but the potential reasons for this were not discussed in the manufacturer's submission. Patients receiving topotecan plus cisplatin experienced a greater number of adverse events and the ERG was concerned with some of the assumptions related to HRQoL. In the base-case direct comparison, the incremental cost

    The infiltration of the parametrium represents one of the most important factors that determine the prediction and treatment of cervical carcinoma. Our objetive is to evaluate the utility of magnetic resonance imaging (MRI) in the staging of cervical carcinomas, to establish the reliability of this technique and to carry out a comparative study of the sequences used to demonstrate the parametrial invasion. We have carried out a retrospective study on 44 patients diagnosed with cervix neoplasia, using clinical exploration and performing a biopsy. the MRI studies have been carried out using a 1 Tesla magnet and the sequences used have been SE T1, Se proton density (PD) and T2 and dynamic GRE after administering gadolinium intravenously in the axial and sagital projections. The stages determined by MRI have been compared to the anatomopathological stages of the surgical specimens in cases where surgery was carried out and with the clinical stage in cases where no radical surgery was carried out. A diagnosis value of MRI has been determined to demonstrate the parametrial invasion, comparing the SE T2 sequence with the dynamic GE sequence with gadolinium. We calculate the volume of the tumour in the MRI studies to evaluate the difference of the volume between patients with tumoral stages that are clinically surgical and not surgical. MRI determines the invasion of the parametrium with a sensitivity of 88.8%, a specificity of 80% a positive value of 76.1%, a negative predictive value of 90.9% and a reliability of 83.7%. For the SE T2 sequences the sensitivity was 86.6%, the specifity 80%, the posistive predictive value 81.25%, the negative predictive value 85.7% and the reliability 83.3%. For the dynamic GE sequence with intravenous gadolinium the sensitivity was 86.6%, the specifity 86.6%, the posistive predictive value 86.6%, the negative predictive value 86.6% and the reliability 86.6%. The use of the dynamic GE sequence after the intravenous administration of

    Cervical incompetence it's a dilatation of the cervix during the third trimester of pregnancy that ends with the interruption of it. The incidence in Chile is about 0.1-2% of the total pregnancies and it's one of the causes of preterm birth. A 34 years old pregnant patient. Timectomized at age 18 to treat her miastenia gravis, previously trated with medication, had 4 previous preterm labours all of them under 25 weeks and vaginal births. All fetuses died postpartum. A cerclage was made during the third, fourth and fifth pregnancies. She didn't present hypertension during the gestation and no cervical diameter under 15mm. Since the fourth gestation the following tests are taken: Antifosfolipidic antibodies, APTT,PT. All the results are either normal or negative. Microbial cultures were negative. No amniocentesis was made. A McDonald cervical cerclage was made during pregnancies number 3, 4 and 5 on the 16th week to delay the labor. Also oral micronized progesterone, on a 400mg/24 hours dosis, was administered to avoid preterm birth. On the 24th week the pharmacological treatment started including Intramuscular Betamethasone, 12 mg/24 hours (2 doses), to induce lung maturity on the fetus. It is thought that the administration of progesterone could have improved the situation of the patient, because it acts as a labour repressants. The use of cerclage could have helped, but the factors that may influence the effectiveness of this method are unknown. Perhaps there is some immunologic factor associated with the miastenia gravis that alters the normal course of pregnancy.

    Prolonged pregnancies are associated with increased rate of maternal and fetal complications. Post term women could be divided into at least two subgroups, one where parturition is possible to induce by prostaglandins and one where it is not. Our aim was to study parameters in cervical biopsies in women with spontaneous delivery at term (controls) and compare to those that are successfully induced post term (responders), and those that are not induced (non-responders), by local prostaglandin treatment. Stromal parameters examined in this study were the accumulation of leukocytes (CD45, CD68), mRNAs and/or proteins for the extracellular matrix degrading enzymes (matrix metalloproteinase (MMP)-2, MMP-8 and MMP-9), their inhibitors (tissue inhibitor of MMP (TIMP)-1 and TIMP-2), interleukin-8 (IL-8), the platelet activating factor-receptor (PAF-R), syndecan-1 and estrogen binding receptors (estrogen receptor (ER)alpha, ERbeta and G-coupled protein receptor (GPR) 30) as well as the proliferation marker Ki-67. The influx of leukocytes as assessed by CD45 was strongest in the responders, thereafter in the controls and significantly lower in the non-responders. IL-8, PAF-R and MMP-9, all predominantly expressed in leukocytes, showed significantly reduced immunostaining in the group of non-responders, while ERalpha and GPR30 were more abundant in the non-responders, as compared to the controls. The impaired leukocyte influx, as reflected by the reduced number of CD45 positive cells as well as decreased immunostaining of IL-8, PAF-R and MMP-9 in the non-responders, could be one explanation of the failed ripening of the cervix in post term women. If the decreased leukocyte influx is a primary explanation to absent ripening or secondary, as a result of other factors, is yet to be established.

    Full Text Available The use of corticosteroids is one of the methods put forward for the strengthening and speeding up the process of labor. After identification of glucocorticoid receptors in human amnion, the role of corticosteroids in starting the process of labor has been studied in numerous studies. The purpose of this study was to determine the effect of intravenous Dexamethasone on preparing the cervix and on labor induction. A randomized, clinical, and double – blind trial was conducted on 172 women divided into a control and an experimental group. The inclusion criteria were that they had to be primparous, in or before the 40th week of pregnancy, and with Bishop scores (B.S.s of 4 or lower. The exclusion criteria were diabetes, preeclampsia, macrosomia, twin pregnancy, rupture of the membrane (ROM, breech, and women suffering from background diseases. The B.S.s of the women was measured in charge of the study, and each woman was intravenously injected with eight milligrams of Dexamethasone or eight milligrams of distilled water. Four hours after the injections, the B.S.s of the participants was measured, and they were put under the conditions of labor induction using oxytocin. Information was collected in checklists A and B. The patients were compared with respect to B.S., the time the induction started, the average interval between the start of induction and the beginning of the active phase of childbirth, and the average length of time between the start of the active phase and the second stage of childbirth. The first and five minutes Apgar scores of the two groups of women were compared. The frequencies, the means,  and the standard deviations were calculated using the SPSS – 16 software, and analysis of the results was performed with the Student’s t- test and the chi-square test with PPPP

    Full Text Available Abstract Background Uterine cervix carcinoma is the second most common female malignancy worldwide and a major health problem in Mexico, representing the primary cause of death among the Mexican female population. High risk human papillomavirus (HPV infection is considered to be the most important risk factor for the development of this tumor and cervical carcinoma derived cell lines are very useful models for the study of viral carcinogenesis. Comparative Genomic Hybridization (CGH experiments have detected a specific pattern of chromosomal imbalances during cervical cancer progression, indicating chromosomal regions that might contain genes that are important for cervical transformation. Methods We performed HPV detection and CGH analysis in order to initiate the genomic characterization of four recently established cervical carcinoma derived cell lines from Mexican patients. Results All the cell lines were HPV18 positive. The most prevalent imbalances in the cell lines were gains in chromosomes 1q23-q32, 3q11.2-q13.1, 3q22-q26.1, 5p15.1-p11.2, this alteration present as a high copy number amplification in three of the cell lines, 7p15-p13, 7q21, 7q31, 11q21, and 12q12, and losses in 2q35-qter, 4p16, 6q26-qter, 9q34 and 19q13.2-qter. Conclusions Analysis of our present findings and previously reported data suggest that gains at 1q31-q32 and 7p13-p14, as well as losses at 6q26-q27 are alterations that might be unique for HPV18 positive cases. These chromosomal regions, as well as regions with high copy number amplifications, coincide with known fragile sites and known HPV integration sites. The general pattern of chromosomal imbalances detected in the cells resembled that found in invasive cervical tumors, suggesting that the cells represent good models for the study of cervical carcinoma.

  7. Cytopathologic evaluation of patients submitted to radiotherapy for uterine cervix cancer

    Full Text Available Summary Cervical cancer is an important public health problem. Pap smear is the leading strategy of screening programs for cervical cancer worldwide. However, delayed diagnosis leads to more aggressive and less effective treatments. Patients with uterine cervix malignancies who are referred for radiotherapy have advanced-stage disease, which results in high rates of locoregional recurrence. The use of radiotherapy as a treatment for cervical cancer causes morphological changes in neoplastic and non-neoplastic epithelial cells, as well as in stromal cells, which make it difficult to diagnose the residual lesion, resulting in a dilemma in cytopathological routine. Based on the difficulties of cytopathologic evaluation for the follow-up of patients treated with radiotherapy for cervical cancer, our objective was to describe the actinic cytopathic effects. Our paper was based on a structured review including the period from June 2015 to April 2016, aiming at an exploratory-descriptive study. Bibliographic investigations were carried out through selection and analysis of articles, list of authors and keywords, selection of new articles focused on the analysis of bibliographic references to previously selected documents, as well as textbooks of recognized merit. The most incident actinic cytopathological alterations as described in the literature are: cellular gigantism, nuclear and cytoplasmic vacuolization, dyskeratosis, bi- and multinucleated (B/M cells, macro and multiple nucleoli, anisokaryosis, anisonucleolosis and nuclear pyknosis. To date, a protocol has not been established that can precisely differentiate the morphological characteristics between benign cells with actinic effects from recurrent malignant cells on post-radiotherapy smears.

    Aberrant activation of the Wnt/β-catenin signaling axis is a prominent oncogenic mechanism in numerous cancers including cervical cancer. Wnt inhibitory factor-1 (WIF1) is a secreted protein that binds Wnt and antagonizes Wnt activity. While the WIF1 gene is characterized as a target for epigenetic silencing in some tumor types, WIF1 expression has not been examined in human cervical tissue and cervical cancer. Here, we show that WIF1 is unmethylated and its gene product is expressed in normal cervical epithelium and some cultured cervical tumor lines. In contrast, several cervical cancer lines contained dense CpG methylation within the WIF1 gene, and expression of both WIF1 transcript and protein was restored by culturing cells in the presence of the global DNA demethylating agent 5-aza-2'-deoxycytidine. Using single-molecule MAPit methylation footprinting, we observed differences in chromatin structure within the WIF1 promoter region between cell lines that express and those that do not express WIF1, consistent with transcriptional activity and repression, respectively. The WIF1 promoter was aberrantly methylated in ∼60% (10 of 17) high-grade highly undifferentiated squamous cell cervical tumors examined, whereas paired normal tissue showed significantly lower levels of CpG methylation. WIF1 protein was not detectable by immunohistochemistry in tumors with quantitatively high levels of WIF1 methylation. Of note, WIF1 protein was not detectable in two of the seven unmethylated cervical tumors examined, suggesting other mechanisms may contribute WIF1 repression. Our findings establish the WIF1 gene as a frequent target for epigenetic silencing in squamous cell carcinoma of the cervix.

    Stratified mucin-producing intraepithelial lesion (SMILE) of the cervix is a human papilloma virus (HPV) associated high grade intraepithelial columnar cell neoplasm that is thought to arise from the reserve cells of the transformation zone. It is composed of immature stratified cells that display intracytoplasmic mucin and is commonly associated with high grade squamous intraepithelial lesion (HSIL), adenocarcinoma in situ (AIS), and invasive carcinoma. Here, we describe the cytologic features of SMILE and discuss its pitfalls in cervical cytology. A 51-year-old woman was diagnosed with SMILE on a cervical biopsy. Histologically, the dysplastic epithelium showed enlarged nuclei with increased nuclear density and presence of mucin-producing columnar cells throughout its thickness. The slides from the last two Pap tests (ThinPrep) performed on the patient were reviewed and compared with the histology. Cytologically, groups of atypical endocervical glandular cells were seen on both Pap tests. These groups showed mild nuclear crowding, slightly enlarged nuclei, nuclear hyperchromasia, and indistinct nucleoli. The borders of these cell groups were relatively smooth. Original cytologic diagnosis was atypical squamous cells of undetermined significance (ASC-US) in both instances. HPV (Hybrid Capture 2) testing was positive on both occasions. Similar to the histology, cytologic features of SMILE are subtle. The features are not typical for AIS or for HSIL and could easily be misinterpreted as reactive. This report emphasizes that careful review of crowded groups of glandular cells in HPV positive women is absolutely critical. Based on our knowledge, this is the first description of the cytologic features of these lesions. Copyright © 2013 Wiley Periodicals, Inc.

    Full Text Available Carcinoma of the cervix is the second most successive reason of female cancer which remains an imperative medical issue in women around the world. Mutations are normally dissected by tissue biopsy which is intrusive, costly and possibly subjective. However, detection of mutations from blood is a non-invasive procedure. However, detection of mutations from blood is a non-invasive procedure. It would offer several advantages, including greater speed and cheap at a cost such that the family members can likewise be screened. Repeated tests after surgery provide an early cautioning for the disease recurrence. The present work aimed to assess the frequency of PIK3CA and HRAS mutations in cervical cancer patients using peripheral blood. This study includes 210 cases presenting cervical cancer and 210 age and sex-matched healthy controls. Genomic DNA was isolated from peripheral blood. The PCR-CTPP method was performed for screening of exons 9 and 20 of PIK3CA and exon 34 HRAS mutations. Sequencing of PIK3CA and of HRAS genes was done for further confirmation. Out of eight mutations studied, no clear disease causing mutations were noticed in any of the cervical cancer patients in the present investigation. Cervical cancer harbors excessive rates of targetable oncogenic mutations. We couldn't find any changes in our investigation. If a connection amongst tissue and non-tissue mutations could be shown, the probability of a basic blood test to distinguish possibility for anticancer treatment comes a bit nearer. Repeated blood tests after surgery provide an early cautioning for disease recurrence. Therefore, in future evaluation of a larger data set and cases with progressive tumor (Stage III–IV will be required to approve these findings.

    Nontuberculous mycobacterial (NTM) infection is increasing across the world. Although the most common clinical manifestation of NTM disease is lung disease, a rare form of disseminated NTM disease has also been documented. Disseminated NTM usually develops in severely immunocompromised individuals, especially those with advanced AIDS. This manifestation is rare in non-HIV-infected hosts and is associated with immunosuppressed conditions. However, recent reports have suggested that disseminated NTM disease in immunocompetent patients without HIV infection has been increasing. Dissemination may involve any organ system, but a case in the female genital tract has never been reported. We report a case in a 67-yr-old previously healthy woman who presented with a disseminated NTM infection in the uterine cervix. The primary presentation was general fatigue and body weight loss. The patient also presented with a mass formation that mimicked cervical cancer on magnetic resonance imaging. In addition to the cervical mass, the patient presented with a mass formation in the omentum; wall thickening of the vagina, bladder, and ureter; and retention of pleural/peritoneal fluid. Vaginal cytology was negative. A diagnosis was made only after detecting acid-fast bacilli in a biopsy specimen of cervical mass, which was conducted under suspicion of cervical malignancy. Then, Mycobacterium avium was confirmed in a polymerase chain reaction test of cervical tissue. After administration of antimycobacterial therapy, the mass and other findings on magnetic resonance imaging disappeared. Infection in multiple organs leads to the diagnosis of disseminated NTM. This case indicates that, for prompt and accurate diagnosis, efforts to detect specific lesions by an imaging study and to confirm diagnosis pathologically are equally important, especially when local cytology is not convincing. The clinical course of this case may serve as a useful reference in the diagnosis and treatment of NTM.

    Tetrazepam is a benzodiazepine derivative clinically used as a muscle relaxant. The aim of the present work was to examine its effect on uterine smooth muscle of the rat in estrus. Tetrazepam required micromolar concentrations to relax contractile responses induced by KCl and acetylcholine in Ca2+ solution, but not oxytocin-induced contraction. In Ca(2+)-free solution, tetrazepam inhibited Ca(2+)-induced contractions in depolarized uterus and vanadate-induced contractions. We suggest that tetrazepam relaxes contractile responses induced by activation of voltage-sensitive calcium channels and receptor-operated calcium channels with little selectivity or that it antagonizes the effect of calcium at subsequent steps, possibly intracellular stores sensitive to vanadate but not sensitive to oxytocin. The inhibition of contraction of rat uterus is not related to high-affinity peripheral benzodiazepine binding sites.

    Full Text Available AIM: This research has aimed to determine knowledge and practice status of nurses about breast self-examination (BSE, clinical breast examination (CBE, mammography and Pap smear and about influencing status of some variables related to these examinations. METHOD: This descriptive study was conducted in an education hospital in Ankara between March 1st and May 30th, 2008. Three hundred-fifty nurses (82.7% have accepted to participate in the study. Data were collected by a questionnaire form including questions about demographics, their knowledge and practice status about BSE, CBE, mammography and Pap smear. Chi-square test, numbers and percentages were used for evaluating the data. RESULTS: Overall, 46.9% of nurses had enough knowledge about early diagnosis of breast and cervix cancer. 60.2% of them can carry BSE, 18.8% can carry out CBE and 7.3% can carry out mammography. Pap smear is carried out by 23.7% of the nurses. Negligence, fear of cancer and thought of finding them unnecessary were determined as reasons for avoidance. Their knowledge and practice were significantly different (p<0.05 according to their age and service where they work. CONCLUSION: It has been concluded that although knowledge and practices of nurses on breast and cervix cancer are at a good level, this isn’t enough when importance of early diagnosis in breast and cervix cancer are taken into consideration, which are among common cancers in women.

    To evaluate if pretreatment HPV titers in cancer cervix could predict radiation response and survival outcomes. Twenty-one patients of cancer cervix were treated by radiotherapy (RT) alone. HPV titers were estimated using DNA Hybrid Capture II test. Loco-regional response at 1 month of RT--complete or partial response (CR and PR respectively) and survival outcomes--local disease-free (LDFS), disease-free (DFS) and overall (OS) survivals were evaluated against pre- and posttreatment HPV titers. Pretreatment HPV titers ranged from 0.81 to 3966.10 RLU/cut off (mean +/- SD: 1264.39 +/- 1148.22, median: 1129.98). Of the demographic features evaluated, mean HPV titers were significantly different only for patients achieving CR or PR at completion of RT (mean +/- SD for CR vs. PR: 1616.31 +/- 1146.86 vs. 384.57 +/- 538.80, P = 0.022). HPV titers at end of RT ranged from 0.12 to 487.42 RLU/cut off (mean +/- SD: 37.31 +/- 108.60, median: 2.33). Patients with higher pretreatment HPV titers (>1000 RLU/cutoff) had a higher CR (P = 0.022) and better survival compared to those with or =99.5% fall in HPV had superior survival outcomes than those with 1000 RLU/cutoff) could be considered as a predictor of radiotherapy response and survival in cancer cervix. A reduction in these titers to 99.5% of their baseline values at end of radiotherapy is also associated with better survival outcomes.

A step-by-step explanation of the procedure using video. Congenital complete vaginal and cervical atresia is rare. Some patients have urinary system abnormality. No standardized surgical treatment guideline was available, and the performance varies for each patient. We performed a robotic-assisted reconstruction of the cervix and vagina using an SIS graft (Cook Medical, Bloomington, IN) and fusion of the hemiuterus for a 12-year-old girl from China diagnosed with congenital vaginal and cervical atresia (U4C4V4). She complained of severe abdominal periodic pain for 2 months. Mammary development and her serum sex hormone were within normal range. The patient has a single kidney. The diagnosis was made according to clinical characteristics, physical examination, and magnetic resonance imaging and classified using the European Society of Human Reproduction and Embryology /European Society for Gynaecological Endoscopy (ESHRE/ESGE) system. There was a hematometra of 7-cm diameter in her pelvis. We constructed a novel vagina by sharp and blunt separation and connected it to the uterine cavity. With the SIS graft, we reconstructed her cervix and vagina, and we fused the hemiuterus to make the uterine cavity spacious. The operating time was 260 minutes, and blood loss was 300 mL. She recovered well after the operation without any complications. After surgery, the patient has had normal menstruation without pain. She insists on wearing the vaginal mold 24 hours per day. The follow-up was 10 months. The length of the vagina was 9 cm and the width was 3 cm. Robotic-assisted reconstruction of the cervix and vagina using an SIS graft and fusion of the hemiuterus is feasible and safety. However, additional studies are required. Copyright © 2016 AAGL.

    Background and purpose: Variations in organ position, shape, and volume cause uncertainties in dose assessment for brachytherapy (BT) in cervix cancer. The purpose of this study was to evaluate uncertainties associated with bladder dose accumulation based on DVH parameter addition (previously...... called "the worst case assumption") in fractionated BT. Materials and methods: Forty-seven patients treated for locally advanced cervical cancer were included. All patients received EBRT combined with two individually planned 3D image-guided adaptive BT fractions. D2 and D0.1 were estimated by DVH...

    We present a case of spontaneous rupture of bladder diverticulum three years after postoperative whole pelvic irradiation (50.4 Gy) for carcinoma of the uterine cervix. The patient had suffered from a neurogenic bladder after hysterectomy, but excretory urography revealed no abnormalities. Bladder diverticulum was found two years later. Spontaneous rupture of the urinary bladder is one of the late complications associated with radiotherapy, although it is very rare. Postoperative neurogenic bladder may also be associated with rupture. We should be aware of this rare complication in patients who receive pelvic irradiation. (author)

  19. Radiation-induced vulvar angiokeratoma along with other late radiation toxicities after carcinoma cervix: A rare case report

    Full Text Available Angiokeratoma including vulvar angiokeratoma is a very rare complication of radiation. Exact incidence is still unknown, we report a case that developed radiation-induced angiokeratoma of skin in the vulvar region along with other late radiation sequelae in the form of bone fracture, new bone formation, bone marrow widening, muscle hypertrophy, and subcutaneous fibrosis, 18 years after radiotherapy to the pelvic region for the treatment of carcinoma cervix. All these late radiation sequel are rare to be seen in a single patient, and none of the case reports could be found in the world literature.

    A clinical treatment delivery platform has been developed and is being evaluated in a clinical pilot study for providing 3D controlled hyperthermia with catheter-based ultrasound applicators in conjunction with high dose rate (HDR) brachytherapy. Catheter-based ultrasound applicators are capable of 3D spatial control of heating in both angle and length of the devices, with enhanced radial penetration of heating compared to other hyperthermia technologies. Interstitial and endocavity ultrasound devices have been developed specifically for applying hyperthermia within HDR brachytherapy implants during radiation therapy in the treatment of cervix and prostate. A pilot study of the combination of catheter based ultrasound with HDR brachytherapy for locally advanced prostate and cervical cancer has been initiated, and preliminary results of the performance and heating distributions are reported herein. The treatment delivery platform consists of a 32 channel RF amplifier and a 48 channel thermocouple monitoring system. Controlling software can monitor and regulate frequency and power to each transducer section as required during the procedure. Interstitial applicators consist of multiple transducer sections of 2-4 cm length × 180 deg and 3-4 cm × 360 deg. heating patterns to be inserted in specific placed 13g implant catheters. The endocavity device, designed to be inserted within a 6 mm OD plastic tandem catheter within the cervix, consists of 2-3 transducers × dual 180 or 360 deg sectors. 3D temperature based treatment planning and optimization is dovetailed to the HDR optimization based planning to best configure and position the applicators within the catheters, and to determine optimal base power levels to each transducer section. To date we have treated eight cervix implants and six prostate implants. 100 % of treatments achieved a goal of >60 min duration, with therapeutic temperatures achieved in all cases.
