    An 18 year old single Jewish woman with the Waardenburg syndrome and absence of a vagina and right sided adnexa uteri is reported. Other congenital malformations associated with the Waardenburg syndrome are mentioned and it is postulated that they may be the result of an altered invasion of neurones or altered neurones in certain organ systems early in embryogenesis.

    of five patients was either constant or decreased a maximum of one line on Snellen's Chart. CONCLUSION: RT is effective in treatment of MALT lymphomas of the ocular adnexa. Rituximab showed an excellent result in one patient with recurrent disease. However, latent infections such as hepatitis B virus......-alpha have shown promising results. MATERIAL AND METHODS: During the 2001-2006 period, nine patients with MALT lymphoma of the ocular adnexa were treated with RT at the Copenhagen University Hospital, Denmark. The visual acuity of six of the nine patients was evaluated before and after receiving RT. RESULTS......: All nine patients achieved complete remission after a total RT dose of 26 Gy. One patient relapsed after 26 months and was then successfully treated with rituximab. Furthermore, one patient experienced a striking improvement of vision after RT: from 2/60 to 6/6 in the affected eye. The visual acuity...

    The present study was conducted with an objective of isolation, in vitro expansion, growth kinetics, molecular characterization and in vitro differentiation of fetal adnexa derived caprine mesenchymal stem cells. Mid-gestation gravid caprine uteri (2–3 months) were collected from abattoir to derive mesenchymal stem cells (MSCs) from fetal adnexa {amniotic fluid (cAF), amniotic sac (cAS), Wharton’s jelly (cWJ) and cord blood (cCB)} and expanded in vitro. These cultured MSCs were used at the 3rd passage (P3) to study growth kinetics, localization as well as molecular expression of specific surface antigens, pluripotency markers and mesenchymal tri-lineage differentiation. In comparison to cAF and cAS MSCs, cWJ and cCB MSCs showed significantly (P<0.05) higher clonogenic potency, faster growth rate and low population doubling (PDT) time. All the four types of MSCs were positive for alkaline phosphatase (AP) and differentiated into chondrogenic, osteogenic, and adipogenic lineages. These stem cells expressed MSC surface antigens (CD73, CD90 and CD105) and pluripotency markers (Oct4, Sox2, Nanog, KLF, cMyc, FoxD3) but did not express CD34, a hematopoietic stem cell marker (HSC) as confirmed by RT-PCR, immunocytochemistry and flow cytometric analysis. The relative mRNA expression of MSC surface antigens (CD73, CD90 and CD105) was significantly (P<0.05) higher in cWJ MSCs compared to the other cell lines. The mRNA expression of Oct4 was significantly (P<0.05) higher in cWJ, whereas mRNA expression of KLF and cMyc was significantly (P<0.05) higher in cWJ and cAF than that of cAS and cCB. The comparative assessment revealed that cWJ MSCs outperformed MSCs from other sources of fetal adnexa in terms of growth kinetics, relative mRNA expression of surface antigens, pluripotency markers and tri-lineage differentiation potential, hence, these MSCs could be used as a preferred source for regenerative medicine.

  9. Sexual dysfunction after radiotherapy for cancer of the cervix uteri

    International Nuclear Information System (INIS)

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

    Full Text Available Background: tumors of the ocular adnexa are a common cause of patient visits to the Ophthalmology consultation. An adequate clinical-pathological relationship is important for prognosis. Objective: to describe the correspondence between clinical and histopathological diagnosis of tumors of the ocular adnexa. Methods: a case series study was conducted in patients who underwent a histopathological study due to suspicion of malignancy treated at the Oculoplastic Service of the Ophthalmology Center of the Dr. Gustavo Aldereguía University General Hospital, from January 2014 to the same month of 2015. The variables analyzed were: age, skin color, type of tumor, correspondence between clinical and histopathological diagnosis and safety margin. Results: correspondence between clinical and histopathological diagnosis was 79.1 %. The 40-59 age group was the most affected, with a higher incidence in females. The most common location was the eyelid region in white patients. Benign lesions of the eyelid and conjunctiva predominated. Conjunctival carcinoma and basal cell carcinoma were the most common malignancies; the safety margin was 2.19 %. Conclusions: an adequate correspondence between presumptive and histopathological diagnosis was observed. The safety margin achieved was satisfactory.

    Full Text Available Abstract Ocular adnexa MALT-lymphomas represent approximatively 5-15% of all extranodal lymphomas. Almost 75% of OAMLs are localized in orbital fat, while 25% of cases involves conjunctive. MALT-lymphomas often recognize specific environmental factors responsible of lymphoma development and progression. In particular as Helicobacter pylori in gastric MALT lymphomas, other bacterial infections have been recognized related to MALT lymphomas in specific site. Recently Chlamydia psittaci has been identified in Ocular Adnexa MALT lymphomas, with variable frequence dependently from geographic areas. Thus bacterial infection is responsible of clonal selection on induced MALT with subsequent lymphoma development. Moreover Chlamydia psittaci could promote chromosomal aberration either through genetic instability as a consequence of induced proliferation and probably through DNA oxidative damage. The most common translocation described in MALT lymphomas affects NF-kB pathway with a substantial antiapoptotic effect. Several therapeutic approaches are now available, but the use of antibiotic-therapy in specific cases, although with conflicting results, could improve the treatment of ocular adnexa MALT lymphomas. In this review we analyse the most relevant features of Ocular adnexa MALT lymphomas, underlining specific biological characteristics mainly related to the potential role of Chlamydia psittaci in lymphomagenesis.

Majority of the patients are in fifth and sixth decades of life with male preponderance. We report here a case of primary extraskeletal myxoid chondrosarcoma of the uterine adnexa involving the broad ligament and fallopian tube synchronously without any evidence of uterine/ovarian involvement in a young multiparous female of 27 years. After the histopathological diagnosis, re-excision of the tumor bed with wide local margins was recommended. Since the tumor has an aggressive course, with propensity for late recurrence and metastases to lungs, the patient must be considered for long-term follow-up.

    Over the past decade, stem cell research has emerged as an area of major interest for its potential in regenerative medicine applications. This is in constant need of new cell sources to conceive regenerative medicine approaches for diseases that are still without therapy. Scientists drew the attention towards alternative sources such as foetal adnexa and fluid, as these sources possess many advantages: first of all, cells can be extracted from discarded foetal material and it is non-invasive and inexpensive for the patient; secondly, abundant stem cells can be obtained; and finally, these stem cell sources are free from ethical considerations. Cells derived from foetal adnexa and fluid preserve some of the characteristics of the primitive embryonic layers from which they originate. Many studies have demonstrated the differentiation potential in vitro and in vivo towards mesenchymal and non-mesenchymal cell types; in addition, the immune-modulatory properties make these cells a good candidate for allo- and xenotransplantation. Naturally occurring diseases in domestic animals can be more ideal as disease model of human genetic and acquired diseases and could help to define the potential therapeutic use efficiency and safety of stem cells therapies. This review offers an update on the state of the art of characterization of domestic animals' MSCs derived from foetal adnexa and fluid and on the latest findings in pre-clinical or clinical setting of the stem cell populations isolated from these sources.

  3. Prognostic implication of apoptosis and angiogenesis in cervical uteri cancer

    International Nuclear Information System (INIS)

    Purpose: A retrospective study was performed to investigate the relationship between spontaneous apoptosis and angiogenesis uterine cervix squamous cell carcinoma patients. The prognostic value of each (and both) of these biologic parameters was also tested. Methods and Materials: The pathologic materials of 40 cervical uteri squamous cell carcinoma patients were examined and immunohistochemically stained to determine the tumor angiogenesis (tumor microvascular score), using factor VIII-related antigen, and their tumor apoptotic index (AI), using the TdT-mediated dUTP nick end-labeling (TUNEL) method. Three patients were Stage I, 18 were Stage II, 15 were Stage III, and 4 were Stage IV (FIGO classification). All patients were treated with radical radiotherapy and all had follow-up for more than 2 years. Results: The mean AI was 15.1 ± 12.8, with a median of 8.3. The mean tumor microvascular score was 3 9.7 ± 14.4, with a median of 3 8. The patients' age and tumor grade did not seem to significantly affect the prognosis. On the other hand, AI and angiogenesis (tumor microvascular score) were of high prognostic significance. The 3-year disease-free survival (DFS) rate for the patients having AI above the median was 78% (confidence interval [CI] 69-87%), compared to 32% (CI 22-42%) for those having AI below the median. The DFS was 18% (CI 9-27%) for patients having an angiogenesis score above the median, while it was 86% (CI 78-94%) for those patients having a score below the median. Conclusion: Determination of both tumor microvascular score and AI can identify patients with the best prognosis of 100% DFS (with low angiogenesis score and high AI). Women with a high score and low AI had the worst prognosis (DFS = 3%, CI 1-5%). Moreover, high AI can compensate partially for the aggressive behavior of tumors showing a high rate of angiogenesis.

    Quantitative analysis of protein phosphorylation provides important insights into molecular signaling mechanisms and a better understanding of many cellular processes. In this study, we coupled stable isotope dimethyl labeling with immobilized metal affinity chromatography (IMAC) enrichment to quantify protein phosphorylation at MS-determined phosphorylation sites. The proposed method was first characterized using alpha- and beta-casein as two model phosphoproteins, and further applied to the analysis of pregnant rat uteri with and without treatment with 8-bromo-cGMP. Dimethyl labeling has several significant advantages: global, fast (within 5 min) and complete (near 100%). Our results indicate that the labeling has no adverse effect on the IMAC enrichment for tryptic peptides having single and multiple phosphorylation sites. Moreover, the enhanced a1 signal and the complete reaction by dimethyl labeling provide unequivocal identification of both the N-terminal amino acid and the number of the labeling site. Using these two criteria in data validation, which is particularly important for identifying phosphoproteins, we found that the confidence in interpreting dimethyl-labeled peptides had greatly increased. In the analysis of late gestation rat uteri, the abundance ratio between treated and un-treated phosphopeptide signals ranged from 0.51 to 1.69 with an average of around 1.01 +/- 0.25. The obtained ratio of the phosphorylation levels at Ser 15 of HSP27 was further confirmed by the consistent results obtained from Western blot analyses. Based on the analysis of the results, it is interesting to note that the activated cGMP dependent protein kinase G (PKG) seems to affect the phosphorylation of proteins associated with the inhibition of cell migration and proliferation, redistribution of actin-associated proteins, and the increase of protein synthesis in late-gestation uteri. These observations provide important evidence suggesting that activated PKG may play a

Three- and five-year overall and relapse-free survival rates have been obtained for stages: 82.5 and 82.5%; 78.4 and 78.4% for Stage IIb; 57 and 52.3%; 41.6 and 41.6 for IIIb; 53.3 and 47.3%; 42.4 and 37.7% for IVb, respectively.

  9. Local use of metronidazole in dimethylsulfoxide in radiotherapy of cervix uteri cancer patients

    International Nuclear Information System (INIS)

    A method of the local use of metronidazole dissolved in dimethylsulfoxide (DMSO) for cervix uteri cancer patients was worked out. Applications of 1-2 g of metronidazole were well tolerated by the patients. Metronidazole concentrations in cervical tumors were high (about 1000 μg/g), in the blood they did not exceed 16 μg/ml. Experiments showed that metronidazole in DMSO diffused in the tissue, its concentrations at a distance of 2-3 cm from the surface were 180-260 μg/g. The local use of metronidazole in DMSO caused an increase in the rate of tumor radiation regression

    A new experimental system was designed to study human uterine activities based on the extra-corporeal perfusion of isolated human uteri. Electromechanical activities in the uterine wall were recorded using bipolar silver-silver electrodes, endoluminal pressure catheters and a dedicated acquisition, storage and analytical system. The electrical signals recorded were isolated spikes and rhythmic activities; the last being primarily associated with organized mechanical events. Perfusion media containing 17 beta-oestradiol alone or with progesterone were used for those uteri obtained during proliferative (n = 5) or secretory (n = 5) phases of the menstrual cycle, respectively. Progesterone caused a reduction of frequency (P < 0.001) and duration (P < 0.001) of the rhythmic electrical activity, and decreased the endoluminal pressure at both detection sites (P < 0.01). 17 beta-Oestradiol increased both frequency (P < 0.001) and duration (P < 0.001) of the rhythmic electrical activity as well as the endoluminal pressure at two different detection sites (3 and 5 cm from the fundus) (P < 0.05). Significant differences between the fundus and cervix sites in the uterine wall were detected. In conclusion, uterine perfusion would be useful to examine the effects of uterotonic and tocolytic drugs before administration to humans, at no risk to the patients. Oestrogens increase and progesterone decreases both electrical and mechanical uterine activities. PMID:8300807

    In this review, we assessed the feasibility of total laparoscopic hysterectomy (TLH) in cases of very large uteri weighting more than 500 grams. We compared surgical outcomes and short term follow-up in 149 patients with the uterus weighing less than 350 g (group A: 40-350 g) and 100 patients with the uterus weighing more than 500 g (group B: 500-1550 g). We discovered no statistical difference between the 2 groups in terms of intraoperative complications (group A: 0%; group B: 2%) and postoperative stay (group A: 3.05 +/- 1.89 days; group B: 3.2 +/- 1.28 days). There were statistically significant differences between the 2 groups in terms of operative time (group A: 101.3 +/- 34.3 min; group B: 149.1 +/- 57.2 min.; p <.0001) and postoperative hospital stay length (group A: 2.8 +/- 0.7 days; group B: 3.5 +/- 1.7 days; p <.0001). No major complications occurred in either group. Postoperative minor complications were more frequent in group B (group A: 8.7%; group B: 18%; p = .03). Median time to well-being was comparable in both groups. In conclusion, TLH is a feasible surgical technique also in cases of very large uteri. An increase in operative time, intraoperative blood loss, hospital stay length, and postoperative minor complications can be expected as the uterine weight increases. PMID:17848315

  12. Estrogen influences dolichyl phosphate distribution among glycolipid pools in mouse uteri

    International Nuclear Information System (INIS)

    To determine the role that dolichyl phosphate availability plays in this induction, the authors studied the effects of estrogen priming on the content of dolichyl phosphate and the distribution of dolichyl phosphate among various glycolipids in uteri. Dolichol-linked saccharides were metabolically labeled to equilibrium with either [3H]glucosamine or [3H]mannose and extracted from primary explants of uterine tissue. The amount of dolichol-linked saccharide was calculated from the specific radioactivity determined for the corresponding sugar nucleotides extracted from the tissues. The major dolichol-linked saccharides identified were mannosylphosphoryldolichol (MPD), oligosaccharylpyrophosphorydolichol (OSL), and N,N'-diacetylchitobiosylpyrophosphoryldolichol (CBL). Estrogen increased the levels of MPD and OSL 4-fold; however, CBL levels did not change. After 3 days of treatment, the levels of these glycolipids were very similar to those in uteri from pregnant mice. The specific activity of GPD synthase was similar under all conditions studied. These studies provide the first determination of the levels of dolichol-linked saccharides in tissues and how these levels change during hormonal induction of glycoprotein assembly. Coupled with earlier studies, the present work demonstrates that among a number of key points of N-linked oligosaccharide assembly and transfer only synthesis of MPD increases coordinately with the increase observed in lipid- and protein-linked oligosaccharide assembly that occurs in vivo in response to estrogen. They suggest that control of MPD levels is an important regulatory aspect of N-linked glycoprotein assembly in this system

    Pyometra, which is accompanied by bacterial contamination of the uterus, is defined as a complex disease associated with the activation of several systems, including the immune system. The objective of the study was to evaluate the gene expression profile in dogs with pyometra compared with those that were clinically normal. The study included uteri from 43 mongrel bitches (23 with pyometra, 20 clinically healthy). RNA used for the microarray study was pooled to four separated vials for control and pyometra. A total of 17,138 different transcripts were analyzed on the uteri of female dogs with pyometra and of healthy controls. From 264 inflammatory response-related transcripts, we found 23 transcripts that revealed a 10- to 77-fold increased expression. Thereby, the expression of interleukin 8 (IL8), interleukin-1-beta (IL1B), interleukin 18 receptor (IL18RAP), interleukin 1-alpha (IL1A), interleukin receptor antagonist (IL1RN) and interleukin 6 (IL6) increased 77-, 20-, 17-, 13-, 13- and 11-fold, respectively. Furthermore, the expression of the calcium binding proteins S100A8 was 44-fold higher, and that of S100A12 and S100A9 37-fold, respectively, in the uteri of canines with pyometra compared with that of the controls. Moreover, the expression of the transcripts of toll-like receptors (TLR8 and TLR2), integrin beta 2 (ITGB2), chemokine ligand 3 (CCL3), semaphorin 7A (SEMA7A), CD14 and prostaglandin-endoperoxide synthase 2 (PTGS2) was increased between 10- and 18-fold. Furthermore, after using RT-qPCR we found an increased expression of AOAH, IL1A, IL8, CCL3, IL1RN and SERPINE 1 mRNAs which can be served also as markers of the occurrence of pyometra in domestic bitches. In summary, it is concluded that up-regulation of interleukins may be used as a marker of the inflammatory response in dogs with pyometra. Moreover, all of the 23 up-regulated transcripts may be novel molecular markers of the pathogenesis of canine pyometra. Several proteins--–products of these

  14. The role of anaemia in the effectivity of radiation treatment of cancer of the collum uteri

    International Nuclear Information System (INIS)

    The role of anaemia is studied in 129 patients with cancer of the collum uteri subjected to combined radiation treatment by comparing data on anaemia and five years survival rates. Since prognosis as well as incidence of anaemia depend on the extend of the disorder the comparison is done for each clinical stage separately. Only in patients found in clinical III b statistical verification (p<0.001) is present witnessing that survival of anaemia patients is shorter than in the rest of the patients. Factors contributing to these differences being discussed a conclusion is drawn that it may be due to a lowered effectivity of the radiation treatment induced by the existing hypoxy. With this regard the relationship is discussed between oxygen tissue diffusion, cellular proliferation of tumors and the effect of ionizing radiation. (author)

    Besides the information regarding his/her disease, each hospitalized cancer patient also provides the variety of data regarding his/her psychological, cultural, social, economical, genetic, constitutional and medical background. The aim of this study was to introduce a holistic approach to analysis of medical data, in this case clinical data regarding cancer of the corpus uteri. Such approach requires the collection of data regarding different aspects of the cancer patient, and after the satisfactory sample size is obtained (which should be at least five times greater than the number of examined patient characteristics), the performance of factor analysis. In this study, the authors have processed the data regarding 25 characteristics of 928 corpus uteri cancer patients treated between 1980 and 1990 at the Department for Gynecological Oncology of the University Hospital for Gynecology and Obstetrics, Zagreb, Croatia. In factor analysis, the principal components were rotated after the initial extraction (the authors recommended the use of oblimin rotation) in order to obtain better ground for interpretation of the obtained results. The next step in this approach was the stepwise exclusion of characteristics with smallest communalities according to Kaiser-Meyer-Olkin criteria, and retaining the characteristics and components with the most significant impact on the explained system variance. When the number of principal components and initial analyzed characteristics was reduced to 3-4 and 7-10, respectively, the ultimate interpretations and conclusions were made. This approach outlined some clusters of correlations between medical data which are difficult to identify using other statistical procedures, primarily the impacts of various socioeconomic and hereditary-constitutional variables on overall survival.

    Full Text Available The objective of the research is to study the possibilities of ozone- and bacteriophage treatment (OBPT in correction of endotoxicosis and immunological disorders in patients of chronic inflammatory diseases of uterine adnexa (CIDUA. Materials and Methods. There have been examined 100 patients with CIDUA, 50 of them have received OBPT, and 50 — traditional treatment. Some parameters of systemic and tissue immunity have been studied. Results and Discussion. The analysis of dynamics of clinical and immune values against the background of the two methods of treatment has revealed that the response to provocation of inflammatory process complication by administration of saturating ozone concentration (5000 mkg/l and Prodigiosan is the increase of intoxication, CIC, IL-6. Henceforth, the compared methods of treatment have showed significant difference. So, OBPT has caused the normalization of the changed acute-phase values, immunological parameters including local ones. The patients’ follow-up within a year has revealed lower recurrence rate of CIDUA complications after OBPT. It makes it possible to consider the method of ozone- and bacteriophage treatment to be pathogenetically reasonable component of complex treatment of chronic inflammatory diseases of uterine adnexa.

    Experimental infection models for Ascaridia galli rely on the use of eggs isolated either directly from worm uteri or from host faeces. We investigated whether A. galli eggs isolated from the two sources differ in their embryonation ability. A. galli eggs originating from 12 worm infrapopulations were isolated both from faeces of the living host (faecal eggs) and directly from worm uteri after host necropsy (uterine eggs). The isolated eggs from each infrapopulation and source were incubated in Petri dishes (n=24) containing a potassium-dichromate (0.1%) medium for 28 days (d) at room temperature. Starting from the day of egg isolation (d0), in ovo larval development was evaluated every second day by examining morphological characteristics of 200 eggs/petri dish. A total of 72,000 eggs were classified into undeveloped, early development, vermiform or fully embryonated stages. Isolation procedures caused similar damage to uterine and faecal eggs (2.2% and 0.5%, respectively; P=0.180). The first sign of in ovo embryonic development in faecal eggs (7%) was observed during the 24-h period when faeces were collected. On d28, a higher percentage of uterine eggs remained undeveloped when compared with faecal eggs (58.6% vs 11.0%; P<0.001). Although a higher (P<0.001) percentage of faecal eggs entered both the early developmental and vermiform stages, which took place primarily within the first two weeks of incubation, there was no time-shift between the development of faecal and uterine eggs. Starting from day 10, higher (P<0.05) percentages of faecal eggs completed embryonation compared with uterine equivalents. Eggs from both sources reached a plateau of embryonation by the end of 2nd week of incubation, with faecal eggs having a greater than two-fold higher embryonation ability. Cumulative mortality was higher in uterine eggs (14.3%) than in faecal eggs (0.2%). We conclude that faecal eggs have a higher embryonation ability than uterine eggs possibly due to maturation

    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 stretched open to a diameter that is more than a tenfold larger than before. During gyneacological interventions, such as artificial inseminations in several animal species, or in women it would be...

  1. Effects of radiotherapy on immunity in patients with localized carcinoma of the cervix uteri

    International Nuclear Information System (INIS)

    To assess the effects of radiotherapy on immune status, a wide range of assessments have been performed on patients with localized carcinoma of the cervix uteri undergoing and initially responding clinically to radical pelvic radiotherapy. neutrophil function was essentially unchanged by treatment. Absolute neutrophil and lymphocyte counts fell after treatment and remained depressed 3 and 12 months following treatment. The proportions of T and B cells dropped with treatment but recovered to near-presentation levels during the follow-up period even though absolute counts remained depressed. In vitro tests of cellular immunity were depressed by treatment and remained so 3 and 12 months following treatment whereas skin test responses remained normal throughout the assessments. Inhibitory plasma effects were observed in photohaemagglutinin lymphocyte transformation studies on 4 untreated patients; at follow-up these effects were not evident. A variable response in immune indices has therefore been observed in patients in remission after treatment of localized carcinoma cervix stressing the importance of assessing several aspects of immune function and implying that persistent depression of certain indices does not adversely affect the host tumor response. In two patients relapsing after apparently good initial response, all aspects of immunological assessment (except serum immunoglobulin levels and neutrophil function) deteriorated

    2014-02-01

    Full Text Available OBJECTIVE: High genistein doses have been reported to induce fluid accumulation in the uteri of ovariectomised rats, although the mechanism underlying this effect remains unknown. Because genistein binds to the oestrogen receptor and the cystic fibrosis transmembrane regulator mediates uterine fluid secretion, we hypothesised that this genistein effect involves both the oestrogen receptor and cystic fibrosis transmembrane regulator. METHODS: Ovariectomised adult female Sprague-Dawley rats were treated with 25, 50, or 100 mg/kg/day genistein for three consecutive days with and without the ER antagonist ICI 182780. One day after the final drug injection, the animals were humanely sacrificed, and the uteri were removed for histology and cystic fibrosis transmembrane regulator mRNA and protein expression analysis using real-time polymerase chain reaction and Western blotting, respectively. The cystic fibrosis transmembrane regulator protein distribution was analysed visually by immunohistochemistry. RESULTS: The histological analysis revealed an increase in the circumference of the uterine lumen with increasing doses of genistein, which was suggestive of fluid accumulation. Moreover, genistein stimulated a dose-dependent increase in the expression of cystic fibrosis transmembrane regulator protein and mRNA, and high-intensity cystic fibrosis transmembrane regulator immunostaining was observed at the apical membrane of the luminal epithelium following 50 and 100 mg/kg/day genistein treatment. The genistein-induced increase in uterine luminal circumference and cystic fibrosis transmembrane regulator expression was antagonised by treatment with ICI 182780. CONCLUSION: Genistein-induced luminal fluid accumulation in ovariectomised rats' uteri involves the oestrogen receptor and up-regulation of cystic fibrosis transmembrane regulator expression, and these findings reveal the mechanism underlying the effect of this compound on changes in fluid volume in

  7. Expression of LIF, VEGF,CD57 and CD68 after the transfer of rat embryos to mouse uteri

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    The high failure rate of interspecific pregnancy is a major obstacle to the successful interspecific cloning of mammals. To investigate the reasons for the failure of interspecfic pregnancy between rats and mice, we transferred rat blastocysts into mouse uteri on the third day of pseudopregnancy (D3). Our previous study showed that intact rat embryos could still be observed in mouse uteri on D9. In the present study, we found that expression of CD57 and CD68 increased significantly at the maternal-fetal interface following the transfer of rat embryos. Similarly, Leukaemia inhibitory factor (LIF) expression increased, but vascular endothelial growth factor (VEGF) expession decreased. In a co-culture system, the percentage of rat ectoplacental cones (EPCs) with adhesion and outgrowth and outgrowth area on mouse uterine decidual cells were less than that of mouse EPCs. These results indicate that an increase in the immunological rejection response and a decrease in the invasiveness of rat embryos may be important reasons for the failure of interspecific pregnancy between rat and mouse.

    The report discusses early-onset radiation injuries in the urinary bladder of more than 1000 patients with cancer of the cervix and corpus uteri. Clinical symptoms of such injuries were observed in 487 patients (44.3%). In 47 (10%), the lesions were pronounced. The degree of radiation-induced cystitis was evaluated on a 6-point scale used by WHO classification (1982). Said lesions mainly occurred at stage III of tumor and predominantly in cases of cancer of the corpus uteri. Complications development was stimulated by vascular lesions, diabetes mellitus and inflammatiry processes in pelvic organs. Radiation injuries were treated by standard procedures as well as with immobilised trypsin administered in a cellulose powder vehicle. this method proved the immobilised trypsin adminstered in a cellulose powder vehicle. This method proved the most effective. Since patients suffering early-onset radiation-induced destructive injuries are at high risk of further exacerbation at later stages, they should be followed-up closely

  11. Preparation of a gap junction fraction from uteri of pregnant rats: the 28-kD polypeptides of uterus, liver, and heart gap junctions are homologous

    OpenAIRE

    1985-01-01

    A procedure for the preparation of a gap junction fraction from the uteri of pregnant rats is described. The uterine gap junctions, when examined by electron microscopy of thin sections and in negatively stained preparations, were similar to gap junctions isolated from heart and liver. Major proteins of similar apparent molecular weight (Mr 28,000) were found in gap junction fractions isolated from the uterus, heart, and liver, and were shown to have highly homologous structures by two-dimens...

  12. In-Vitro effect of Ficus deltoidea on the contraction of isolated rat’s uteri is mediated via multiple receptors binding and is dependent on extracellular calcium

    Science.gov (United States)

    2013-01-01

    Background Ficus deltoidea, is a perennial herb that is used to assist labor, firm the uterus post-delivery and to prevent postpartum bleeding. In view of its claimed uterotonic action, the mechanisms underlying plant’s effect on uterine contraction were investigated. Methods Adult female SD rats were injected with 2 mg/kg 17β-oestradiol (E2) to synchronize their oestrous cycle. A day after injection, uteri were removed for in-vitro contraction studies. The dose dependent effect of Ficus deltoidea aqeous extract (FDA) on the tension produced by the isolated rat’s uteri was determined. The effects of atropine (2×10-8 M), atosiban (0.5 IU), THG113.31 (10 μM), oxodipine (0.25 mM), EDTA (1 mM), 2-amino-ethoxy-diphenylborate (2-APB) (40 mM) and thapsigargin (1 mM) on the maximum force of contraction (Emax) achieved following 2 mg/ml FDA administration were also investigated. Results FDA induced in-vitro contraction of the isolated rat’s uteri in a dose-dependent manner. Administration of atropine, atosiban and THG113.31 reduced the Emax with atosiban having the greatest effect. The Emax was also reduced following oxodipine and EDTA administration. There was no significant change observed following 2-APB administration. Thapsigargin, however, augmented Emax. Conclusions FDA-induced contraction of the isolated rat’s uteri is mediated via multiple uterotonin receptors (muscarinic, oxytocin and prostaglandin F2α) and was dependent on the extracellular Ca2+. Contraction, however, was not dependent on the Ca2+ release from the internal stores. This in-vitro study provides the first scientific evidence on the claimed effect of Ficus Deltoidea on uterine contraction. PMID:24330515

    Pyometra is recognized as one of the main causes of disease and death in the bitch, and Escherichia coli is the major pathogen associated with this disease. In this study, 70 E. coli isolates from the uteri horn, mouth, and rectum of bitches suffering from the disease and 43 E. coli isolates from the rectum of clinically healthy bitches were examined for the presence of uropathogenic virulence genes and susceptibility to antimicrobial drugs. DNA profiles of isolates from uteri horn and mouth in bitches with pyometra were compared by REP, ERIC, and BOX-PCR. Virulence gene frequencies detected in isolates from canine pyometra were as follows: 95.7% fim, 27.1% iss, 25.7% hly, 18.5% iuc, and 17.1% usp. Predominant resistance was determined for cephalothin, ampicillin, and nalidixic acid among the isolates from all sites examined. Multidrug resistance was found on ∼ 50% pyometra isolates. Using the genotypic methods some isolates from uteri, pus, and saliva of the same bitch proved to have identical DNA profiles which is a reason for concern due to the close relationship between household pets and humans.

    Full Text Available Human papillomavirus (HPV that is a main cause of cancer of the cervix uteri (CCU has immunogenic properties, i.e. an abilityto activate antiviral immunity responses as adaptive HPV-specific and innate ones. For this reason, despite multiple mechanisms generated by HPV to avoid immunity responses, the human body can eliminate the infection in most cases. At the same time, CCU results from the combined influence of many factors of different nature, among which the factors that impair the normal course of an immune response are of vital importance.This review describes the major factors and mechanisms, which promote the establishment of persistent HPV infection and the progression of dysplasia to cancer, on the one hand, and allow the tumor cells in CCU to restrict the body’s immune reactions, on the other Immune disorders induced by the virus and/or tumor cells are considered at both local and systemic levels. Particular emphasis is placed on the molecular mechanisms that can change the population composition and functional activity of leukocytes and the cytokine profile of cells and can form the tumor suppressor microenvironment.

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

    International Nuclear Information System (INIS)

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

    Full Text Available Today, the common term metabolic syndrome encompasses visceral (abdominal obesity, glucose intolerance, type 2 diabetes mellitus (DM, hypertension, and dyslipidemia. In Europe, the rate of obesity mong the women ranges from 6 to 36 %. In the USA, 65 % of the adult population is overweight and 30 % is obese. High estrogen production in adipose tissue in patients with obesity has been established to increase the risk of cancer of the corpus uteri (CCU by 4 times as compared to that in normal weight female patients. Furthermore, obese patients are at increased risk for DM that is also a risk factor for CCU. A rise in the number of obese patients leads to the population redistribution of gynecological cancer. The increasing number of patients with gynecological cancer is overweight. This patient group has an increased risk from surgery and anesthesia, a higher incidence of postoperative complications, and delayed recovery. Laparotomy increases the duration of hospital stay and the rate of wound complications. The frequency of urologic injuries in obese patients varies between 2 and 4 %. In this patient category, the rate of damage to the large vessels or bowels has also statistically significant differences. The literature highlights a number of complications specific to patients with obesity: trocar damage to anterior abdominal wall vessels, particularly to the inferior epigastric artery, urinary bladder, as well as trocar site hernia. The authors describe their experience in treating CCU patients with metabolic syndrome at the Department of Surgery for Female Reproductive System Tumors, N. N. Blokhin Russian Cancer Research Center. They demonstrate that laparoscopic extirpation of the uterus and its appendages can be performed in patients with third-degree obesity (weighing 174 kg in Stage I CCU. It should be noted that this weight was previously regarded as an absolute contraindication to surgical treatment.

    2008-02-01

    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

    Full Text Available Abstract Introduction Persistent Mullerian duct syndrome is a rare form of male pseudo-hermaphroditism characterized by the presence of Mullerian duct structures in an otherwise phenotypically, as well as genotypically, normal man; only a few cases have been reported in the worldwide literature. We report the case of a 30-year-old man with unilateral cryptorchidism on the right side and a left-sided obstructed inguinal hernia containing a uterus and fallopian tube (that is, hernia uteri inguinalis; type I male form of persistent Mullerian duct syndrome coincidentally detected during an operation for an obstructed left inguinal hernia. Case presentation A 30-year-old South Indian man was admitted to our facility with a left-sided obstructed inguinal hernia of one day's duration. He had a 12-year history of inguinal swelling and an absence of the right testis since birth. Our patient had well developed masculine features. Local physical examination revealed a left-sided obstructed inguinal hernia with an absence of the right testis in the scrotum. Exploration of the inguinal canal revealed an indirect inguinal hernia containing omentum, the left corner of the uterus and a left fallopian tube. Extension of the incision revealed a well formed uterus, cervix and upper part of the vagina attached to the prostate by a thick fibrosed band. Total excision of the uterus, bilateral fallopian tubes and right testis was performed. A biopsy was taken from the left testis. The operation was completed by left inguinal herniorraphy. Histopathological examination of the hernial contents was consistent with that of a uterus and fallopian tubes without ovaries. Both testes were atrophied, with complete arrest of spermatogenesis. Post-operative karyotype analyses were negative for 46,XY and Barr bodies on buccal smear. A semen examination revealed azoospermia with a low serum testosterone level. Conclusions In cases of unilateral or bilateral cryptorchidism

We hypothesize that P inhibits uterine fluid secretion and HCO3- transport. Aim. to investigate the expression of Cystic Fibrosis Transmembrane Regulator (CFTR and Cl−/HCO3- exchanger (SLC26A6 under P effect. Method. Uteri from ovariectomized steroid replaced and intact rats at different stages of oestrous cycle were analyzed for changes in protein and mRNA expressions. Results. P inhibits CFTR and SLC26A6 proteins and mRNA expression while oestrogen (E causes vice versa. E treatment followed by P causes a reduction in these transporters’ mRNA and protein. Similar changes occur throughout the oestrous cycle; that is, CFTR mRNA expression was high at proestrus while SLC26A6 mRNA and protein expressions were increased at proestrus and estrus. At diestrus, however, the expression of these transporters’ protein and mRNA was reduced. Conclusion. Inhibition of CFTR and SLC26A6 expressions may explain the reduced fluid volume and pH under P-mediated effect.

  4. Using the Computed Tomography in Comparison to the Orthogonal Radiography Based Treatment Planning in High dose Rate (HDR) Brachytherapy in Cervical Uteri Cancer Patients; A Single Institution Feasibility Study

    International Nuclear Information System (INIS)

    Brachytherapy is an integral part in the treatment of cervical uteri cancer patients. Orthogonal treatment planning is the standard mode of calculation based on reference points. Introduction of the innovative 3-D computer based treatment planning allows accurate calculation based on volumetric information as regards the target volume and organs at risk (OAR). Also provide dose volume histogram (DVH) for proper estimation of the dose in relation to the volume. Aim: To correlate and compare the information obtained from the two approaches for high dose rate brachytherapy of cervical uteri cancer; the orthogonal conventional method and the computerized tomography (CT) three dimensions (3D) based calculation method in relation to the target and organ at risk (OAR). Methods: From 6 patients of cervical uteri cancer, 21 applications with orthogonal planning using the Brachy Vision treatment planning system version 7.3.10 were performed. In 10 applications; comparison between orthogonal and CT based planning was done. In orthogonal planning; the dose to point A, rectum and bladder were defined according to the American Brachytherapy Society (ABS) recommendation. From the CT based planning the target volume and dose volume histogram (DVH) were calculated for the clinical target volume (CTV), rectum and bladder. From these two sets, information was obtained and compared and mean values were derived. Results: For dose prescription at point A, an average of 63.5% of CTV received the prescribed dose. The mean ICRU dose to the bladder point is 2.9 Gy±l .2 SD (Standard Deviation) and 17% of the bladder volume derived from CT was encompassed by 2.9 Gy isodose line. The mean ICRU dose at the rectum point is 3.4 Gy±1.2 SD and 21% of the rectum volume from CT was encompassed by 3.4 Gy isodose line. The maximum dose to the rectum and the bladder derived from the CT and compared to the maximal dose at ICRU is 1.7 and 2.8 times higher than the orthogonal reference points; with the

    2012-01-01

    Conclusions: The umbrella cells may be mistaken for dysplastic cells originating in low grade squamous intraepithelial lesions lesions (LSILs due to their nuclear and cytoplasm sizes. Therefore, it is important to know the possibility of their appearance in the cervical smears, especially in post menopausal patients in order to avoid a false diagnosis of an intraepithelial lesion. It is unlikely that deeper cells of urothelium would be confused with high grade squamous intraepithelial lesion (HSIL cells. However, their presence might be a reason of mistake in the diagnosis. TCM is an under-recognized metaplastic phenomenon of the cervix and vagina, which is a mimicker of high-grade squamous intraepithelial lesion. The differential characteristic between umbrella cells, cells from TCM and the deeper urothelial cells, and LSIL and HSIL are detailed in the present paper.

  9. Errors in the imaging diagnosis of septate versus bicornuate uteri

    International Nuclear Information System (INIS)

    Until recently the accuracy of the preoperative diagnosis of a uterine anomaly was not critical because both the septate uterus and the bicornuate uterus were corrected by transabdominal procedures. However, the preoperative distinction between these two congenital Mullerian defects is now critical since the uterine septum can be incised successfully with hysteroscopic metroplasty. Unfortunately, the appearance of the abnormal uterine configuration on hysterosalpingography is often reported as bicornuate uterus even though only the internal configuration of the uterus has been imaged and the external confirguration is undetermined. Frequently the abnormality is actually a septate uterus. The authors present a diagnostic protocol for working up Mulllerian defects seen on hysterosalpingograms. Seven examples are used to illustrate the key role in US in accurately elucidating the full extent of the congenital lesion, with follow-up hysterosalpingography after hysteroscopic metroplasty used to demonstrate the appearance of the uterus after this therapy

    Full Text Available Carotenoids and retinyl esters are the source of vitamin A in the human body and its natural derivatives takes part in the regulation of cell replication and differentiation in the human endometrium, may induce the leiomyoma growth and has a role in differentiation of endometrial adenocarcinoma. The aim of the study was to demonstrate the presence of carotenoids in tissues from the normal uterus and from various tumors of the uterine corpus, as well as to compare the total content, major carotenoids and % of carotenoids belonging to the provitamin A group between the tissues examined. Using three independent methods of chromatography (CC, TLC, HPLC we analysed 140 human samples. We identified 13 carotenoids belonging to the eg. provitamin A group and epoxy carotenoids. In all the samples beta-carotene, beta-cryptoxanthin, lutein, neoxanthin, violaxanthin and mutatoxanthin were isolated. In normal tissues, the mean carotenoid content was the highest in the follicular phase endometrium (9.9 microg/g, while the highest percentage of carotenoids belonging to provitamin A group was found in the luteal phase (18.2%. In the pathological group, the highest mean values were demonstrated for epithelial lesions (8.0 microg/g, and within this group - in endometrioid adenocarcinoma (10.8 microg/g. In both groups, violaxanthin, beta-cryptoxanthin, lutein epoxide and mutatoxanthin were the predominant carotenoids. We have demonstrated that all uterine tissues show a concentration of beta-carotene and beta-cryptoxanthin, being the source of vitamin A. The highest total values of carotenoids obtained in the group of endometrioid adenocarcinoma seem to confirm certain enzymatic defects in carotenoid metabolism in the course of the neoplastic process or some metabolic modifications. The finding of astaxanthin - the major antioxidant among carotenoids - in 63% of tissues examined is also significant.

    that 8-Cl-cAMP diminished uterus weight but did not modify significantly its histopathology or the estral cycle; Tam diminished uterus weight showing cystic hyperplasia and estral cycle arrested at diestrus; MPA treatment produced the increase of uteri weight, caused an endometrium edematization and a pseudopregnancy estral cycle. When combined with 8-Cl-cAMP, Tam or MPA always had the predominant effect. The importance studying the effect of the combination of antineoplastic drugs on non-transformed target-tissues, is highlighted even if transductional pathways of action are different.

The cutaneous changes, such as allergic dermatitis, are well reported, but the ocular changes associated with eye cosmetic use are less so. Some pigmented cosmetic products may accumulate within the lacrimal system and conjunctivae over many years of use, but immediate reports of eye discomfort after application are most common. Changes to the tear film and its stability may occur shortly after application, and contact lens wearers can also be affected by lens spoliation from cosmetic products. Additionally, creams used in the prevention of skin aging are often applied around the eyes, and retinoids present in these formulations can have negative effects on meibomian gland function and may be a contributing factor to dry eye disease. The aim of this review is to summarize current knowledge regarding the impact of cosmetic products on the eye, ocular surface, and tear film. PMID:26398576

    Inherited mutations in BRCA1 and BRCA2 increase significantly the risk of developing breast and ovarian cancers, and they have been associated with increased risks of developing other types of cancer. Although screening programs have been implemented in order to detect cancers at the early stage, they resulted ineffective. To date, risk-reducing bilateral salpingo-oophorectomy represents the only procedure allowing reducing the incidence of ovarian cancer and increasing survival among BRCA1 and -2 mutation carriers. In the present review we will discuss the advantages and disadvantages related to the execution of prophylactic surgery, thus underlying possible beneficial and detrimental effects of this kind of surgery in premenopausal women. Additionally, we will investigate further therapeutic strategies aimed to reduce the risk of developing ovarian cancer, without affected patients' hormonal status. PMID:26844708

Methods From September 2011 to November 2012, 59 uterine myometrial specimens were obtained from 59 cases underwent hysterectomy, including 28 adenomyosis patients as adenomyosis (ADS) group and 31 patients with cervical intraepithelial neoplasia Ⅲ as control group. EMI smooth muscle cells were cultured and loaded with calcium ion fluorescent probe fluo-4/AM. After treated with trisphosphate (IP3) receptor antagonist, blocker of sarcoplasmic reticulum calcium-adenosine triphosphate (ATP), depleted agent of the ryanodine receptor-operated Ca2+, inhibitor of L-type calcium channel, inhibitor of Na+-Ca2+exchanger, the labeled cells were stimulated with estrogen. The changes of intracellular Ca2+fluorescence intensity were detected by laser scanning microscopy. The changes of intracellular Ca2+concentration was indicated byΔF[Ca2+]i. Results (1) Under normal calcium conditions, after the stimulation of estrogen, intracellular Ca2+fluorescence intensity in ADS group and control group both increased than those without estrogen. TheΔF[Ca2+]i in ADS group was 384±26, and in the control groupΔF[Ca2+]i was 235±20. TheΔF[Ca2+]i in ADS group was higher than that in the control (P0.05). But, the ΔF[Ca2 +]i in ADS group was significantly reduced after treatment compared to before treatment, (211 ± 19 vs 384 ± 28; P=0.001). The increase in control group was almost the same with before (203±16 vs 234±22, P=0.141). (4) After treated with inhibitor of Na+-Ca2+exchanger, theΔF[Ca2+]i in ADS group was 357 ± 24 and in the controlΔF[Ca2+]i was 209±19. The increase in ADS group was significant higher than that in the control (P=0.000). Compared withΔF[Ca2+]i on the condition without treating with

    The report presents results of investigation of the neck of the womb (cervix) of 64 women aged from 19 to 70, that formed 4 clinical groups (1st group: 15 women without any pathology of the cervix, 2nd group: 27 women with the erosion, 3rd group: 11 women with dysplasia, 4th group: 11 women with cancer of the cervix). The aim of this research is to assess the capabilities of electrical impedance tomography in the diagnostics of the cervix diseases. The methods of the research were: visual examination with the speculum, colposcopy, and biopsy of the cervix. Also the new method of visualization of the cervix was used - electrical impedance tomography with the help of gynecological impedance tomograph (GIT). The following results were obtained. The electrical conductivity of the cervix in norm and in different pathology has different indices, which allow differential diagnostics of benign and malignant diseases. Summary: the method of electrical impedance tomography allows not only visually estimate portio vaginalis, but receive indices of electrical conductivity of the cervix on the depth up to 0.8 cm and thereby reveal pathological changes in epithelium without invasive and operative intervention.

    Full Text Available Uterine artery embolization (UAE is minimally invasive, less complicated and uterine-preserve procedure when compared to traditional surgical options. Magnetic resonance imaging (MRI is the preferred modality in gynecologic pathology visualization. MRI is more accurate than transvaginal ultrasound in evaluating number, size and structure of the fibroids as well as their vascularization (by means of contrast enhancement on pre-UAE uterus. On post-UAE contrast enhanced MRI, performed in 1, 6 and 12 month after the procedure, shrinkage of fibroids as well as the absence of their enhancement can be registered, showing the success or the manipulation. In case when leiomyoma is accompanied with adenomyosis, poor response of UAE can be noted by means of enhanced MRI revealing revascularization of fibroids. Thus, enhanced MRI is essential in UAE efficiency assessment, predicting treatment response and it’s complications.

  1. Adenomyosis uteri in infertile women: experience in a tropical community teaching hospital

    International Nuclear Information System (INIS)

    To determine the demographic pattern and clinical presentation of 23 infertile women with intraoperative diagnosis of adenomyosis followed by histopathologic confirmation. A review of 23 consecutive infertile women that underwent surgery due to preoperative misdiagnosis for uterine fibroids over a period of 5 years. The patients mean age was 37.3 years with age range of 26 to 47 years. Only five patients (21.7%) had delivered before. Eighteen patients (78.3%) had had abortion(s) in the past. Secondary infertility accounted for 78.3% and 21.7% had primary infertility. Past gynaecological procedures included dilatation and curettage or manual vacuum aspiration in 17 (73.9%) patients, previous adhesiolysis for uterine synaechiae in 3 (13.1%) patients and past history of myomectomy in 5 (21.7%) patients. Preoperative hysterosalpingogram showed only 2 patients (8.7%) with bilateral tubal patency and 17 patients (73.9%) had bilateral tubal blockage. Unilateral patency of the fallopian tube was observed in 4 (17.4%) patients. Amongst patients with bilateral tubal blockage, cornual blockages were mostly encountered in 15 (88.2%) of the 17 patients. The modes of clinical presentation were abdominopelvic mass 100%, dymenorrhoea 82.6%, menorrhagia 60.9%, dyspareunia 47.8% and metrorrhagia in 34.8% of cases. Intraoperatively adenomyosis encountered were diffuse adenomyosis in 13 (56.5%) patients, multiple focal adenomyosis in 7 (30.4%) patients and unifocal adenomyosis in 3 (13.1%) patients. Co-existing uterine fibroid were found in 17 (73.9%) of the 23 patients. Two patients (8.7%) had coexisting endometriosis. At surgery, significant pelvic adhesion was encountered in 7 (30.4%) patients. In infertile women, adenomyosis is significantly associated with proximal tubal occlusion and tends to co-exist with insignificant uterine fibroids. (author)

    The causes of precancerous and cancerous diseases of the cervix are disputed. In women with menstrual disorders usually benign cervical disease is 5 times higher. In the 1960s the theory of hormonal genesis of cervical disease was advanced as similar pathogenetic processes in the cervix, endometrium, myometrium, and breasts resulted in hyperplastic changes in these organs. Ectopia can occur during sexual maturation under the influence of sex hormones. The maximum frequency (65.5%) of ectopia occurred up to age 20. Cervical ectopia can occur under use of oral contraceptives (OCs) for 6-12 months but it vanishes after discontinuation. In a study of 17,942 women aged 18-58 increased risk of preinvasive carcinoma of the cervix was found under longterm use of OCs. Increased frequency of cervical intraepithelial neoplasm from .9/10,000 women/year to 2.2/10,000 women/year was found only under longterm (up to 8 years) of OC use. An epidemiological investigation of 47,000 women using OCs for up to 10 years concluded that there was significant increase of frequency of cervical cancer compared with nonusers. It was 4 times higher in those taking OCs for over 10 years, although longterm use reduced uterine and ovarian cancer. Adenomatous hyperplasia of the endocervix was 14 times more frequent in OC users. In a sample of 128 women, 44% of whom were OC users, 24% had microglandular hyperplasia. Under the use of the 3-phase preparation Trisiston for 6 months-1 year ectopia was diagnosed in 13.6% of women that disappeared after cessation of use. Early cancer and dysplasia disappeared in 1/3 of women taking Enovid for 6-30 months after diagnosis. OCs promote the prophylaxis against genital cancer because women taking OCs undergo gynecological and cytological examinations more often, thus precancerous changes can be diagnosed early. The optimal and the safest method of contraception has to be chosen to minimize the effect on the cervix. PMID:1789353

    Full Text Available Background: To estimate the efficacy of daily administration of 25 mg mifepristone for the treatment of uterine leiomyoma. Materials and Methods: A total of 30 women were to receive 25 mg mifepristone daily for a period of 6 months. Abdominal ultrasonography was performed before treatment, at 3 months and after 6 months, to evaluate the leiomyoma size and uterine volume. Endometrial biopsy was done after the treatment. Efficacy was estimated by the reduction in leiomyoma size, uterine volume, and improvement in quality of life. Results: After 180 days of treatment, there was a 47% decrease in the leiomyoma volume and a 53% decrease in the uterine volume. Symptomatic improvement was noted. Twenty-three of 30 women (75.7% became amenorrheic after the treatment. Endometrial biopsy after treatment revealed simple hyperplasia in two of 30 women. Conclusion: 25 mg mifepristone produces reduction in leiomyoma size and uterine volume and produces symptomatic improvement in women with fibroids.

  5. Effects of radiotherapy on immunity in patients with cured localized carcinoma of the cervix uteri

    International Nuclear Information System (INIS)

    The effects of radiotherapy on immune status in patients with localized carcinoma of the cervix have been assessed serially up to 5 years remission by a wide range of methods. Neutrophil function and serum immunoglobulins were essentially normal throughout. Peripheral blood neutrophil and lymphocyte counts and the proportions of T and B-cells fell with treatment but were all normal at 5 years, with the exception of B-cell proportions which remained significantly low. Marked deterioration was seen in in vivo cellular immune responses and this persisted even at 5 years remission. Reduced in vitro immunoreactivity is not therefore a reliable marker of disease recurrence and persisting defects in cellular immunity after radiotherapy do not seem to adversely affect the host tumor response. However, in three of the six patients who subsequently relapsed after therapy, subnormal PHA lymphocyte transformation responses were observed at presentation; all patients achieving sustained remission had normal pretreatment responses

  6. A Systematic Overview of Radiation Therapy Effects in Cervical Cancer (Cervix Uteri)

    International Nuclear Information System (INIS)

    A systematic review of radiation therapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately. This synthesis of the literature on radiation therapy for cervical cancer is based on data from 1 meta-analysis and 34 randomized trials. In total, 35 scientific articles are included, involving 7,952 patients. The results were compared with those of a similar overview from 1996 including 34,024 patients. The conclusions reached can be summarized in these points: There are limited scientific data supporting that postoperative pelvic radiotherapy improves disease-free survival in early cervical cancer. No firm conclusion can be drawn. There is moderate scientific evidence that external beam radiotherapy combined with brachytherapy gives a similar disease-free and overall survival rate as radical hysterectomy in early cervical cancer. There is strong scientific evidence that concomitant radiochemotherapy improves disease-free and overall survival compared to radiotherapy alone in early cervical cancer. The NCI has recently published an announcement stating that cisplantin-based chemotherapy should be used concomitantly with radiotherapy in cervical cancer. No solid documentation for this statement can be found concerning locally advanced stages (>IIB). There is a strong scientific evidence that cisplatin-based chemotherapy given concomitantly with radiotherapy is superior to concomitant chemotherapy with hydroxyurea. There is no scientific evidence to show that neoadjuvant chemotherapy followed by radiotherapy improves disease-free or overall survival compared to radiotherapy alone in patients with localized cervical cancer. There is moderate scientific evidence that high-dose-rate brachytherapy gives the same local control rate as low-dose-rate brachytherapy but with fewer rectal complications

    Full Text Available Cervical cancer (CC morbidity is analyzed on the basis of the data of the Karelian cancer register over the period 1998-2007. During this period, 816 cases of CC were registered and 126 were found at an antenatal clinic (AC. Its early detection rate was ascertained to be 96% during screening at the AC. A comprehensive examination was made in 1742 women with various cervical diseases, of them 37.5% were infected with human papillomavirus (HPV. High-grade dysplasia and carcinoma in situ were diagnosed in 6.6% of the HPV-infected patients. Large-scale screening for HPV infection and pretumor disorders with their further treatment will aid in reduc- ing CC morbidity and mortality rates.

    Full Text Available Orbital marginal zone B-cell lymphoma (OAML constitutes for the most frequent diagnosis in orbital lymphoma. Relatively little data, however, have been reported in larger cohorts of patients staged in a uniform way and no therapy standard exists to date.We have retrospectively analyzed 60 patients diagnosed and treated at our institution 1999-2012. Median age at diagnosis was 64 years (IQR 51-75 and follow-up time 43 months (IQR 16-92. All patients had undergone uniform extensive staging and histological diagnosis was made by a reference pathologist according to the WHO classification.The majority of patients presented with stage IE (n = 40/60, 67%, three had IIE/IIIE and the remaining 17 stage IVE. Seven patients with IVE had bilateral orbital disease whereas the others showed involvement of further organs. Treatment data were available in 58 patients. Local treatment with radiotherapy (14/58, 24% or surgery (3/58, 5% resulted in response in 82% of patients. A total of 26 patients (45% received systemic treatment with a response rate of 85%. Nine patients received antibiotics as initial therapy; response rate was 38%. Watchful-waiting was the initial approach in 6/58 patients. In total 28/58 patients (48% progressed and were given further therapy. Median time-to-progression in this cohort was 20 months (IQR 9-39. There was no difference in time-to-progression after first-line therapy between the different therapy arms (p = 0.14. Elevated beta-2-microglobulin, plasmacytic differentiation, autoimmune disorder and site of lymphoma were not associated with a higher risk for progress.Our data underscore the excellent prognosis of OAML irrespective of initial therapy, as there was no significant difference in time-to-progression and response between local or systemic therapy. In the absence of randomized trials, the least toxic individual approach should be chosen for OAML.

    Clinical endometritis is an important disease of dairy cattle and results in decreased reproductive performance. This disease is caused by contamination of the uterus with a broad spectrum of microorganisms after calving. In this study, staphylococcal isolates from the uterus of dairy cows with clinical endometritis were tested for their distribution of superantigen (SAg) genes and antimicrobial resistance. Between the 127 staphylococcal isolates collected in this study, 10 species were identified. The predominant strain identified was Staphylococcus aureus (n=53), followed by Staphylococcus saprophyticus (n=38) and Staphylococcus chromogenes (n=22). PCR analysis demonstrated that most isolates (63.0 per cent) harboured at least one SAg gene. The most commonly observed SAg gene and genotype was selj (38.6 per cent) and sec-selj-seln (24.0 per cent), respectively. Most isolates were resistant to penicillin (79.5 per cent), ampicillin (71.7 per cent), erythromycin (56.7 per cent), and tetracycline (52.0 per cent). PCR analysis demonstrated that the antimicrobial resistance determinants ermA, ermB, ermC, tetK, tetM and blaZ were detected in 0 per cent, 44.4 per cent, 51.4 per cent, 68.2 per cent, 13.6 per cent and 86.1 per cent of the erythromycin, tetracycline and β-lactam resistant isolates, respectively. There were 22 (17.3 per cent of all isolates) coagulase-negative staphylococci shown to be methicillin resistant. In the methicillin-resistant isolates, significant resistances to ampicillin, erythromycin and penicillin were observed (P<0.01). The results of this study demonstrate that staphylococci recovered from dairy cows with clinical endometritis contain an extensive and complex prevalence of SAg genes. Significant resistances to antibiotics were also seen, highlighting the need for the rational appliance of antibiotics in veterinary medicine. PMID:24989035

    Full Text Available Trial of labor after cesarean section can be a choice on maternity with cesarean history. The successful trial of labor is then called vaginal birth after a cesarean (VBAC. The failure on VBAC is often caused by hypotonic uterine inertia. Oxytocin infusion augmentation is not a contraindication; it is a solution for increasing success on VBAC with requisite continuing observation. The aim of this research was to determine the successful differences of VBAC on hypotonic uterine inertia with and without oxytocin augmentation. This research was an experimental study on randomized clinical trial, using 40 patients with history of cesarean section at Dr. Hasan Sadikin Hospital and two satellite hospitals (Sumedang and Astana Anyar during March–May 2009 which fulfilled inclusion criteria divided into two groups; the group using oxytocin infusion and the group without oxytocin infusion. The patients’ characteristic, the success on VBAC and the maternal complication also neonatal condition were noted as encode. Chi-square test was used for statistical analysis. There was no statistical significant difference of success between the group used oxytocin infusion (80% and the group without using oxytocin infusion (60% with p>0.05 (p=0.168, but using confidence interval 95% showed the successful on VBAC with oxytocin infusion was greater 1.71 (0.72–4.06. The maternity and neonatal complication on two groups did not indicate a significant difference. In conclusion, using oxytocin infusion on hypotonic uterine inertia can increase the success on VBAC

    Purpose: To validate a Monte Carlo model and evaluate the dosimetric capabilities of a novel commercial CT/MR compatible Fletcher applicator for cervical cancer brachytherapy. Methods: MCNPX 2.7.0 was used to model the Fletcher CT/MR shielded applicator (FA) and 192Ir HDR source. Energy deposition was calculated with a track length estimator modified by an energy-dependent heating function. A high density polystyrene phantom was constructed with three film pockets for validation of the MCNPX model. Three planes of data were calculated with the MCNPX model corresponding to the three film planes in phantom. The planes were located 1 cm from the most anterior, posterior, and medial extents of the FA right ovoid. Unshielded distributions were calculated by modeling the shielded cells as air instead of the tungsten alloy. A third order polynomial fit to the OD to dose curve was used to convert OD of the three film planes to dose. Each film and MCNPX plane dose distribution was normalized to a point 2 cm from the center of the film plane and in a region of low dose gradient. MCNPX and film were overlaid and compared with a distance-to-agreement criterion of (±2%/±2mm). Shielded and unshielded distributions were overlaid and a percent shielded plot was created. Results: 85.2%, 97.1%, and 96.6% of the MCNPX points passed the (±2%/±2mm) criterion respectively for the anterior, lateral, and posterior film comparison planes. A majority of the points in the anterior plane that exceeded the DTA criterion were either along edges of where the film was cut or near the terminal edges of the film. The percent shielded matrices indicated that the maximum % shielding was 50%. Conclusion: These data confirm the validity of the FA Monte Carlo model. The FA ovoid can shield up to 50% of the dose in the anteroposterior direction.

The adenomyoses were classified as superficial and deep. The morphology, staining and vascularization of the corpus luteum and the presence or not of larger ovarian follicles than 8mm helped to estimate tthe estrus cycle. The cows in anestrus (n=11 showed the least occurrence of adenomyosis (8.2% and the animals in the medium luteal phase (n=21 the largest one(31,0%. In the initial luteal phase (n=13 and the follicular phase (n=16 the occurrences of adenomyosis were similar and equals to 18.0 and 22.9%, respectively.

    Purpose: To assess survival, disease-specific survival, acute and late toxicity and quality of life in patients with curable endometrial carcinoma treated with adjuvant or primary radiotherapy at the age {>=}75 years. Patients and methods: In a prospective study, outcome was regularly assessed in 49 patients treated between 1991 and 1995 at a median age of 78.4 years. Radiotherapy was applied using the same concept as in younger patients. Thirty-eight patients received postoperative adjuvant radiotherapy (vaginal insertions only: n=18; external and vaginal insertions: n=17; external radiotherapy only: n=3), 8 patients were treated for a vaginal recurrence. Three patients received primary radiotherapy. Median pelvic dose was 39.6 Gy (ICRU) with 1.8 Gy per fraction (4 fields). Vaginal HDR radiotherapy consisted of 5 times 5 Gy at 0.5 cm depth in cases with no external radiotherapy, and of 3 times 5 Gy in addition to pelvic radiotherapy, respectively. Median follow-up was 3.2 years. The EORTC QLQ-C30 was used for self-assessment of quality of life. Results: Survival and disease-specific survival at 5 years was 64% and 84%, respectively. There was no pelvic or vaginal recurrence in patients with Stage IA to IIB. Patients with positive adnexa and those treated for vaginal recurrence relapsed in 50%. Two patients (4%) did not complete radiotherapy because of severe diarrhea. Grade 4 late complications were observed in 1/38 patients following adjuvant radiotherapy and in 2/8 patients treated for a recurrence. The actuarial rate of Grade 3 to 4 complications was 7% at 3 years. Quality of life was good in most cases and remained constant over time. (orig.)

  1. Imaging methods for ovarian tumours

    International Nuclear Information System (INIS)

    The present paper compares the results of MRT with sonography in 64 patients with tumours of the adnexa in 35 patients examined by CT. There was no difference between these three imaging methods as regards lateralisation of the lesion. MRT provided better differentiation because of the excellent demonstration of the uterus and of tumours of the adnexa. Detailed tissue characterisation, particularly as regards cystic lesions, provides improved diagnostic information. MRT has problems, however, because of its low spatial resolution and the difficulty in differentiation from bowel loops. At present sonography and CT is better at establishing a differential diagnosis. CT remains the method of choice for tumour staging. (orig.)

    2006-08-01

    Full Text Available Reports of uterine cancer deaths that do not specify the subsite of the tumor threaten the quality of the epidemiologic appraisal of corpus and cervix uteri cancer mortality. The present study assessed the impact of correcting the estimated corpus and cervix uteri cancer mortality in the city of São Paulo, Brazil. The epidemiologic assessment of death rates comprised the estimation of magnitudes, trends (1980-2003, and area-level distribution based on three strategies: i using uncorrected death certificate information; ii correcting estimates of corpus and cervix uteri mortality by fully reallocating unspecified deaths to either one of these categories, and iii partially correcting specified estimates by maintaining as unspecified a fraction of deaths certified as due to cancer of "uterus not otherwise specified". The proportion of uterine cancer deaths without subsite specification decreased from 42.9% in 1984 to 20.8% in 2003. Partial and full corrections resulted in considerable increases of cervix (31.3 and 48.8%, respectively and corpus uteri (34.4 and 55.2% cancer mortality. Partial correction did not change trends for subsite-specific uterine cancer mortality, whereas full correction did, thus representing an early indication of decrease for cervical neoplasms and stability for tumors of the corpus uteri in this population. Ecologic correlations between mortality and socioeconomic indices were unchanged for both strategies of correcting estimates. Reallocating unspecified uterine cancer mortality in contexts with a high proportion of these deaths has a considerable impact on the epidemiologic profile of mortality and provides more reliable estimates of cervix and corpus uteri cancer death rates and trends.

  8. Imaging diagnosis of enlarged uterus

    International Nuclear Information System (INIS)

    We evaluated ultrasonographic and MRI findings of 24 histologically proven cases of enlarged uterus, which consisted of 19 cases of myoma uteri and 7 cases of adenomyosis. Preoperative diagnostic accuracy was 70% for ultrasonography , and 96% for MR imaging. In this retrospective study comparing with macroscopic specimens, there was no significant difference between myoma uteri and adenomyosis on sonographic appearances, while significant differences were observed on MRI in regard to the margin of the lesions, myometrial contour, and presence of internal high intensity spots. Furthermore, MR imaging reflected macroscopic appearance of specimens more accurately. However, there were some diagnostic pitfalls even on MR imaging. (author)

Ophthalmomyiasis externa is a limited superficial infestation of external ocular structures such as conjunctiva and adnexae. A case of follicular carcinoma thyroid with orbital metastasis presenting as ophthalmomyiasis externa is reported. The patient presented with foul smelling ulcers of the medial and lateral orbital walls of the right eye extending into the lids and nose, teeming with maggots. Computerized Tomography (CT) showed widespread bone destruction with extension into surrounding sinuses. Over 200 maggots were manually removed after immobilisation with turpentine oil instillation. Entomological examination showed it to be a case of accidental myiasis caused by the common housefly Musca domestica. The patient was managed conservatively and the ulcer cavities filled up with healthy granulation tissue. This case is presented on account of its rarity. PMID:24145557

    Full Text Available Background: The aim of this study was to report our results on premenarchal girls with adnexal torsion who were treated with different approaches. Materials and Methods: Twenty-six adnexal torsions in children were analysed retrospectively. Group 1 included cases of oophorectomy for the twisted adnexa. Group 2 contained the patients with adnexal torsion who untwisted either with a laparoscopic or open approach. Postoperative restoration of ovarian function was evaluated by Doppler ultrasound at the 6 th month. All oophorectomy and biopsy specimens were also evaluated. Results: Group 1 consisted of eleven cases that underwent oophorectomy due to gangrenous change and haemorrhagic infarction. Histology was of a mature teratoma in two cases and haemorrhagic necrosis due to torsion in seven. Group 2 consisted of 15 patients. In 10 out of 15 patients, preoperative biopsy is performed in which their histology revealed haemorrhagic necrosis in eight cases, and simple cyst with a benign nature in two cases. In all of the 10 untwisted adnexas, postoperative radiological imaging showed complete recovery with normal follicular development. No malignancy or increased tumour markers were noted in both groups. Conclusion: Adnexas can be left in place regardless of the preoperative degree of necrosis. Biopsy can be added to the procedure to rule out malignancy.

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the feasibility of three-dimensional dynamic MR hysterosalpingography (3D MR HSG) for visualization of the cavum uteri and demonstration of bilateral fallopian tube patency as an alternative to conventional hysterosalpingography. Five infertile female patients underwent 3D dynamic MR HSG prior to conventional hysterosalpingography. The MR protocol consisted of axial T1-weighted spin-echo (SE), axial/coronal T2-weighted fast SE (FSE), and 3D MR angiography sequences before, during, and after injection of a diluted gadolinium solution into the cavum uteri via a balloon catheter. Positioning of the catheter was feasible in all patients. In one patient the catheter slipped out during MRI and in one patient the catheter was placed far in the cavum uteri. In three patients catheter position was optimal at the level of the cervical canal. Evaluation of pelvic anatomy, myometrium, and ovaries was possible in all patients on the basis of T1-weighted SE and T2-weighted FSE. Three-dimensional visualization of the dilated cavum uteri was possible in four patients. In these four patients 3D MR HSG also proved bilateral fallopian tube patency which was confirmed in each patient by conventional hysterosalpingography. Three-dimensional MR HSG is feasible and further research should be done to determine if this technique can evolve into an alternative technique to conventional hysterosalpingography with the advantages of no radiation and additional visualization of the uterus wall and ovaries.

More than 50% of the 5-year RSR were achieved in cancers of the eye, skin, larynx and tongue treated by radical R. There were no cases cured by palliative R. The cases treated by preoperative R, combined with ST, were those of the cervix uteri; and those by postoperative R alone were cancers of the larynx, skin, cervix uteri, eye, breast and thyroid. A remarkable improvement of the 5-year RSR in R was seen in cases of surgical R using an electron beam on bladder cancer, and also in those of electron external R on cancers of the skin, lymph nodes and reticulm cell sarcoma. The high energy X-ray beam was usefull for retinoblastoma, cancers of the cervix uteri, larynx and pharynx. Although there was an increase in the number of long term survivors, this success was offset by a decline in the rate of rehabilitation to society due to radiation injury and an occurence of R-induced cancer and leukemia.

    Full Text Available Abstract Background The aim of this retrospective study was to describe the spectrum of genital and associated malformations in women with Mayer-Rokitansky-Küster-Hauser syndrome using evaluated diagnostic procedures and the Vagina Cervix Uterus Adnex – associated Malformation classification system (VCUAM. Methods 290 women with MRKH syndrome were clinically evaluated with using clinical examinations, abdominal and perineal/rectal ultrasound, MRI, and laparoscopy. Results Classification of female genital malformation according to the Vagina Cervix Uterus Adnex – associated Malformation classification system was possible in 284 women (97.9%. Complete atresia of Vagina (V5b and bilateral atresia of Cervix (C2b were found in 284 patients (100%. Uterus: bilateral rudimentary or a plastic uterine horns were found in 239 women (84.2%. Adnexa: normal Adnexa were found in 248 women (87.3%. Malformations: associated malformations were found in 126 of 282 evaluable women (44.7%, 84 women (29.6% had malformations of the renal system. Of 284 women with Mayer-Rokitansky-Küster-Hauser syndrome 212 women (74.7% could be classified as V5bC2bU4bA0. The most frequent classification was V5bC2bU4bA0M0 (46.8% diagnosed in 133 of 284 women. Conclusions Complete atresia of vagina and cervix were found in all patients, variable malformations were found with uterus and adnexa. A variety of associated malformations were present, predominantly of the renal system. It is therefore recommended that all patients with genital malformations should be evaluated for renal abnormalities.

    Full Text Available Laparoscopic management of most of the adnexal masses has become feasible in the present era of advancing endoscopic techniques. A postmenopausal lady presented with lump in the abdomen, appeared to be a solid ovarian mass on ultrasound, and magnetic resonance imaging. On laparoscopy, both the ovaries were normal and the mass was not connected to uterus or adnexa. The mass was removed and histopathology confirmed it to be ovarian tissue thus confirming it to be a tumor in a supernumerary ovary. Examples of supernumerary ovary are among the rarest of gynecological abnormalities.

    Erlotinib is a tyrosine kinase inhibitor of the epidermal growth factor receptor. Since there is a wide expression of the epidermal growth factor receptors in the epithelial tissues of ocular surface and adnexa, ocular adverse reactions may happen during systemic administration of erlotinib. Previously reported ocular adverse reactions of erlotinib include trichomegaly, periorbital rash, ectropion, blepharitis, persistent corneal epithelial defect, corneal ulcer and perforation. We report the first case of erlotinib-related keratopathy in a patient who had received laser in situ keratomileusis. The patient presented a special picture of flap striae related to erlotinib. Improvement of keratopathy after cessation of erlotinib was demonstrated. PMID:26340340

    Horner's syndrome is characterized by a combination of ipsilateral miosis, blepharoptosis, enophthalmos, facial anhidrosis, and iris heterochromia in existence of congenital lesions. The syndrome results from a disruption of the ipsilateral sympathetic innervation of the eye and ocular adnexa at different levels. Though rare, thyroid and neck surgery could be considered as possible causes of this clinical entity. We present a case of Horner's syndrome in a patient after total thyroidectomy and neck dissection for medullary thyroid cancer with neck nodal disease and attempt a brief review of the relevant literature.

    Full Text Available Keratoconjunctivitis sicca, or dry eye, is a common ocular disease prompting millions of individuals to seek ophthalmological care. Regardless of the underlying etiology, dry eye has been shown to be associated with abnormalities in the pre-corneal tear film and subsequent inflammatory changes in the entire ocular surface including the adnexa, conjunctiva and cornea. Since the recognition of the role of inflammation in dry eye, a number of novel treatments have been investigated designed to inhibit various inflammatory pathways. Current medications that are used, including cyclosporine A, corticosteroids, tacrolimus, tetracycline derivatives and autologous serum, have been effective for management of dry eye and lead to measurable clinical improvement.

    During mouse pregnancy, uterine stromal cells transform into morphologically distinct decidual cells under the influence of the implanting embryo and a proper hormonal environment. Mechanical stimulation of hormonally primed uterine stromal cells leads to the same morphologic alterations. The....... Mouse decidual cells isolated from 6- to 7-day pregnant uteri explanted in vitro continue to synthesize basement-membrane-like extracellular matrix. Using immunohistochemistry and metabolic labeling followed by immunoprecipitation, SDS-PAGE, and fluorography, it was shown that the decidual cells...... undergo pseudodecidualization. We thus showed that stromal cells from pregnant and nonpregnant mouse uteri synthesize significant amounts of basement-membrane components in vitro, and hence could serve as a good model for the study of normal basement-membrane components....

    International Nuclear Information System (INIS)

    Objective: To discuss the feasibility and safety of uterine artery chemoembolization in the treatment of cervical pregnancy. Methods: During the period of Sep. 2005-Dec. 2007, uterine artery chemoemboliztion was performed in 12 patients with cervical pregnancy in the authors' hospital. Via bilateral uterine arteries 100 mg MTX and 80,000 U Gentamycin were infused separately, after that the bilateral uterine arteries were embolized with gelfoam. Cleaning of the uterus and the cervix uteri was carried out in 24 -72 h after the procedure. Results: The technical success rate of bilateral uterine artery chemoembolization was 100%. The blood loss was 50-100 ml (mean 65 ml) during the procedure of cleaning the uterus and the cervix uteri. No serious complications occurred. Conclusion: Uterine artery chemoembolization is an effective and safe treatment for cervical pregnancy, which can greatly avoid unnecessary uterectomy and preserve fertility function. (authors)

    International Nuclear Information System (INIS)

    Using a radioimmunoassay of hormones, disorders in the system of hormonal relations were revealed in 210 patients with malignant ovarian and sorpus uteri tumors and correlated with a clinical course of disease. The recovery of the hormonal balance can serve an objective criterion for the evaluation of therapeuti efficacy and for a search for new antitumor drugs and means of correction of the disturbed feedback between hypophyseal and ovarian functions as one of the main factors of the pathogenesis of malignant ovarian and corpus uteri tumors. The author describes the importance of radionuclide methods in vitro for an all-round control over changes in the respective components of the neuroendocrine system in treatment of dyshormonal tumors and possibilities of their use in screenings of the hormonal status

    S100A10 belongs to the S100 calcium binding protein superfamily, and functions as one of the mediators of calcium-dependent signaling pathway. Recently, S100A10 gene was proved to be significantly up-regulated at the implantation site. In the present study, semi-quantitative reverse transcriptase-polymerase chain reaction and in situ hybridization are used to investigate the tissue-specificity of S100A10 expression and the expression pattern of S100A10 in the uteri during the estrous cycle and pregnancy. Meanwhile, the regulation of S100A10 expression by sex steroid hormones is studied in ovariectomized mice. The results show that S100A10 could be detected in various kinds of tissues, with relatively high expression in reproductive tracts including ovary, uterus, testis and epididymis.During pregnancy, the expression of S100A10 in the uteri is significantly up-regulated on the 4th day. The transcript is strongly detected in endometrial stromal cells and weakly in luminal epithelium cells at the implantation site, but almost not at the inter-implantation site.From gestational day 5 till labor, S100A10 mRNA maintains a certain level in both uteri and placentae. During the estrous cycle, expression of S100A10 is up-regulated in the uteri at proestrus and estrus. Estradiol significantly induces the expression of S100A10, while progesterone can abolish the effect of estradiol. The data suggests that S100A10 may be involved in preventing luminal epithelial cells from over-apoptosis, inducing proliferation and decidualization of stromal cells during implantation, and responding to reproductive stress triggered by copulation.

  18. Basic studies on the human uterus by magnetic resonance imaging

    International Nuclear Information System (INIS)

    This study was designed to analyze characteristic features of the human uterus by using a 0.5 Tesla super-conducting magnet. Relative square ratios of the endometrium and the junctional zone to the uterine body were measured during menstrual cycle with a computed image analyser. Nine healthy volunteers aged 21 to 30 years underwent magnetic resonance imaging (MRI) in the proliferative, secretory, and menstrual phases. Relaxation times of the endometrium, junctional zone, and myometrium were determined. The relative ratio of the endometrium to the uterine body was 13.8% in the proliferative phase, 17.9% in the secretory phase, and 8.0% in the menstrual phase. The ratio of the junctional zone decreased from 26.6% in the proliferative phase to 23.4% in the secretory phase, and increased to 35.0% in the menstrual phase. Relaxation times of the endometrium and junctional zone were the shortest in the menstrual phase. For the myometrium, T1 values showed the same tendency. T2 values were the shortest in the proliferative phase. MRI was also performed in 39 patients with hydatidiform (one), myoma uteri (11), adenomyosis uteri (one), carcinoma of the uterine body (3), and carcinoma of the uterine cervix (23). Myoma nodule without degeneration appeared at low intensity, and had the shortest T1 and T2 values. Myoma uteri with degeneration had an increased intensity and larger T1 and T2 values. Adenomyosis uteri showed a diffuse low intensity with high intensity spots. Malignant lesions of both the uterine body and cervix showed a high intensity on T2-weighted image and similar T1 and T2 values. These T1 and T2 values were, however, shorter than tissue of unmarried normal women. MRI was considered useful for the observation of menstrual cyclic and quantitative change in the human physiologic uterus, as well as for the differentiation of malignant from benign uterine diseases.

    Two patients with radiation ulcers of the lower abdomen which had occurred after radiotherapy for cancer of the cervix uteri and was repaired with groin flap were reported. Effects of flaps in plastic and reconstructive surgery were also referred to. Besides defects in the lower abdomen, defects in the vulva, the perineum, and the upper region of the femur were probably reconstructed effectively with groin flaps.

    Full Text Available Of the approximately 80,000 new cases of all cancers detected every year in India, 10-15% are gynecological malignancies. As per population-based registries under the National Cancer Registry Program, the leading sites of cancer among women are the cervix uteri, breast, and oral cavity. About 50-60% of all cancers among women in India are mainly of the following four organs: cervix uteri, breast, corpus uteri, and ovaries. Over 70% of these women report for diagnostic and treatment services at an advanced stage of disease, resulting in poor survival and high mortality rates. Among all gynecological cancers, ovarian cancer is the deadliest one and, in 2/3 rd of the cases, is detected in an advanced stage. But, in India and in other developing countries, due to inadequate screening facilities for the preventable cancer cervix, this kills more women than any other cancer in females. Gynecology Oncologist as a sub-specialist has an immensely important role in curtailing the menace of gynecological malignancies by providing comprehensive preventive, curative, palliative and follow-up services, with the aim of assuring a good quality of life to women as a cornerstone of cancer management.

    Mouse and vole embryos were allogeneically and xenogeneically transferred into pseudopregnant CD.1 and immunodeficient (seid)female mice,and we investigated the distribution of uterine leucocytes cells in the implantation sites on days 5,6,and 7 of pregnancy. Maerophages were evenly distributed in the endometrium on days 5-7.Neutrophils were rarely seen on days 5-7,but lymphocytes were found throughout the endometrium,often in groups associated with glands or the luminal epithelium.The number of uNK cells increased markedly at the mesometrial uriangle and the outer decidual area in the CD-1 uteri containing vole embryos;by contrast,seid uteri having vole embryos showed almost the same number as those having mouse embryos.Mast cells were present in large numbers at the myometrium,but rarely in the decidua in all types of pregnant uteri.Cells at the myometrium were more numerous in xenogeneic than in allogeneic transfer.Maay mast cells appeared in the inner decidua where xenogeneically transferred vole embryos were dead and aborted.These results suggest the possibility that uterine leucocytes mediate various immunological events in the mouse-vole interspesific pregnancies.

    Full Text Available Introduction. Pediatric surgeons often practice pediatric gynecology. The single-incision single-instrument (SISI technique used for appendectomy is applicable in gynecologic surgery. Methods. We retrospectively analyzed the records of patients undergoing pelvic surgery from 2008 to 2013. SISI utilized a 12 mm transumbilical trocar and an operating endoscope. The adnexa can be detorsed intracorporeally or extracorporealized via the umbilicus for lesion removal. Results. We performed 271 ovarian or paraovarian surgeries in 258 patients. In 147 (54%, the initial approach was SISI; 75 cases (51% were completed in patients aged from 1 day to 19.9 years and weighing 4.7 to 117 kg. Conversion to standard laparoscopy was due to contralateral oophoropexy, solid mass, inability to mobilize the adnexa, large mass, bleeding, adhesions, or better visualization. When SISI surgery was converted to Pfannenstiel, the principal reason was a solid mass. SISI surgery was significantly shorter than standard laparoscopy. There were no major complications and the overall cohort had an 11% minor complication rate. Conclusion. SISI adnexal surgery is safe, quick, inexpensive, and effective in pediatric patients. SISI was successful in over half the patients in whom it was attempted and offers a scarless result. If unsuccessful, the majority of cases can be completed with standard multiport laparoscopy.

    Full Text Available The trigeminal nerve carries the sensory innervation of the eye and adnexa in three divisions: ophthalmic, maxillary, and mandibular. The sensory fibres of the eye and adnexa are found in the ophthalmic division – with the exception of a portion of the sensory input from the lower lid, which is carried by the maxillary division. Blocking the sensory fibres provides anaesthesia so that no pain is felt.The motor supply of the extraocular muscles and levator palpebrae superioris is carried by the oculomotor (III, trochlear (IV, and abducens (VI nerves. Paralysing these muscles by blocking their motor supply provides akinesia so that the eye does not move during surgery.The motor supply of the orbicularis oculi, which is responsible for the gentle and forcible closure of the eye, is carried by the facial nerve (VII. Blocking these fibres will provide better surgical exposure. It also reduces the risk of forcing out the ocular contents if the patient tries to close his eyelids forcibly after the surgeon opens the globe.

    To evaluate the CT findings of ruptured corpus luteal cysts. Six patients with a surgically proven ruptured corpus luteal cyst were included in this series. The prospective CT findings were retrospectively analyzed in terms of the size and shape of the cyst, the thickness and enhancement pattern of its wall, the attenuation of its contents, and peritoneal fluid. The mean diameter of the cysts was 2.8 (range, 1.5-4.8) cm; three were round and three were oval. The mean thickness of the cyst wall was 4.7 (range, 1-10) mm; in all six cases it showed strong enhancement, and in three was discontinuous. In five of six cases, the cystic contents showed high attenuation. Peritoneal fluid was present in all cases, and its attenuation was higher, especially around the uterus and adnexa, than that of urine present in the bladder. In a woman in whom CT reveals the presence of an ovarian cyst with an enhancing rim and highly attenuated contents, as well as highly attenuated peritoneal fluid, a ruptured corpus luteal cyst should be suspected. Other possible evidence of this is focal interruption of the cyst wall and the presence of peritoneal fluid around the adnexa.

    Type II endometrial carcinomas (ECs) are estrogen independent, poorly differentiated tumors that behave in an aggressive manner. As TP53 mutation and CDH1 inactivation occur in 80% of human endometrial type II carcinomas, we hypothesized that mouse uteri lacking both Trp53 and Cdh1 would exhibit a phenotype indicative of neoplastic transformation. Mice with conditional ablation of Cdh1 and Trp53 (Cdh1(d/d)Trp53(d/d)) clearly demonstrate architectural features characteristic of type II ECs, including focal areas of papillary differentiation, protruding cytoplasm into the lumen (hobnailing) and severe nuclear atypia at 6 months of age. Further, Cdh1(d/d)Trp53(d/d) tumors in 12-month-old mice were highly aggressive, and metastasized to nearby and distant organs within the peritoneal cavity, such as abdominal lymph nodes, mesentery and peri-intestinal adipose tissues, demonstrating that tumorigenesis in this model proceeds through the universally recognized morphological intermediates associated with type II endometrial neoplasia. We also observed abundant cell proliferation and complex angiogenesis in the uteri of Cdh1(d/d)Trp53(d/d) mice. Our microarray analysis found that most of the genes differentially regulated in the uteri of Cdh1(d/d)Trp53(d/d) mice were involved in inflammatory responses. CD163 and Arg1, markers for tumor-associated macrophages, were also detected and increased in the uteri of Cdh1(d/d)Trp53(d/d) mice, suggesting that an inflammatory tumor microenvironment with immune cell recruitment is augmenting tumor development in Cdh1(d/d)Trp53(d/d) uteri. Further, inflammatory mediators secreted from CDH1-negative, TP53 mutant endometrial cancer cells induced normal macrophages to express inflammatory-related genes through activation of nuclear factor-κB signaling. These results indicate that absence of CDH1 and TP53 in endometrial cells initiates chronic inflammation, promotes tumor microenvironment development following the recruitment of macrophages

    ABSTRACT Purpose: To assess the effect of patient education on videotaped topical instillation of artificial tear drops on subsequent topical instillation. Materials and methods: Forty-five patients, who had been using glaucoma drops for at least 6 months and with a best-corrected visual acuity of 20/100 or better, were studied. The patients were asked to instill an artificial tear drop using their accustomed technique while being video recorded. The patients viewed the recordings, and the errors in their drop instillation method were pointed out. This was followed by an educational session on proper drop instillation technique. After 30 minutes, patients were videotaped instilling drops to ascertain the effect of the educational session. The variables compared were: number of drops instilled, number of drops reaching the ocular surface, and the number of times the tip of the medication bottle touched the eye or ocular adnexa. Results: Before the instruction session, patients squeezed an average of 1.5 ± 0.9 drops from the bottle, and the average number of drops reaching the conjunctival fornix was 0.9 ± 0.7. The tip of the bottle touched the ocular adnexa in 29/45 (64.4%) patients. After the education session, the patients squeezed an average of 1.2 ± 0.5 drops and an average of 1.2 ± 0.4 drops reached the conjunctival fornix. The tip of the bottle touched the ocular adnexa in 13/45 (28.9%) patients. With proper instructions, the percentage of patients that instilled just one drop on the eye increased from 66 to 82%. Conclusion: A single educational session on the proper use of topical drops improves the successful instillation of eye drops. However, it was not determined whether the patients will retain the improved instillation technique for long-term or if the intervention results in only a short-term improvement.

    Full Text Available Introduction: Bilateral adnexectomy is a surgical procedure that is frequently associated with total hysterectomy performed for benign uterine conditions. Given the relatively wide range of indications for the aforementioned type of salpingo-ooforectomy which in it self is not devoid of potential risks the patients' and physicians' decision-making should take into account several parameters (most helpful to individualize treatment such as published ratio of removal versus conservation of uterine adnexae, patients' age, pre/postmenopausal status at the time of surgery, relevant family and personal history including current use of hormonal replacement therapy. Material and Method: This retrospective cohort study was conducted among 457 women aged 18 years or older who underwent abdominal total hysterectomies for benign uterine conditions between 2000 and 2011. The study patients were stratified by age for better characterization and according to recent publications. Results: Uni- or bilateral oophorectomy was performed in 50% of the subgroup of hysterectomized women younger than 35 years old whereas in the other half of the same age category of patients the uterine adnexas were conserved. Among the study patients aged between 35 and 45 years in 50.5% of the cases the unilateral type of oophorectomy was undertaken while for the other 49.5% of women the bilateral adnexectomy was the rule. Finally, in all patients older than age 45 years the bilateral salpingo-oophorectomy was the procedure of choice. Moreover, out of the 55 study patients in which at least one ovary was preserved, 30.9% of cases underwent the removal of the remaining adnexa when affected de novo by malignant (n=3 or benign (n=14 pathology. Last but not least, in order to reduce both cancer risks and early menopause hazards, our analysis based on recent literature attempted to identify patient characteristics (relevant factors associated with or without bilateral oophorectomy at the

  2. Study on nucleodiagnosis of uterine tumors with 201thallium chloride

    International Nuclear Information System (INIS)

    A total of 50 cases, including 29 of myoma uteri, 8 of adenomyosis, 7 complicated with both of the diseases and 6 of carcinoma corporis uteri, were given 201thallium chloride (201Tl-Cl) intravenously, and were scanned by a gamma-camera 20 min later. The positive image of 201Tl-Cl accumulations was obtained in all cases. The minimal detectable size of the myoma nodules found in our studies was greater than 5 cm. The cases of adenomyosis and carcinoma corporis uteri had generally a slightly stronger accumulation of 201Tl+ than did the myoma. However, the objective diagnostic criteria for each tumor could not be established in the course of this study from the scanning images exclusively. The uterus was 1.7 to 1.9 times more radioactive than the background in the image analysis by the RI-minicomputer, and in the study of extirpated specimens, the myomatous lesion was 1.8 to 1.85 times more radioactive than the myometrium. The distribution of 201Tl+ was almost uniform in the myoma nodules. The accumulation of 201Tl+ was extremely rapid in tumors, and reached to saturation within 15 min after the intravenous administration. Tl+ as a K+ analog was thought to be incorporated by the tumor cells which were already in an advanced K+-metabolic state. Tumor scanning with 201Tl-Cl is useful for RI diagnosis in the gynecological field because it is a quick and safe method, and yields a relatively clear image. (author)

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

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

    Highlights: •We first examined the expression of Cxcl14 in MLAp and DB of uterus. •We found the uNK cells in MLAp and decidua express Cxcl14. •In Cxcl14{sup −/−} placenta, we found significantly decreased uNK cells. •We first performed microarray to compare the gene expression in MLAp and DB. -- Abstract: The uterine natural killer cells (uNK cells) are the major immune cells in pregnant uterus and the number of uNK cells is dramatically increased during placentation and embryo development. The uNK cells are necessary for the immune tolerance, cytokine secretion and angiogenesis of placenta. Former studies indicated that the population expansion of uNK cells was accomplished through recruitment of NK cell precursors from the spleen and bone marrow, but not proliferation of NK cells. However, the necessary molecules within this process were little understood. Here in our study, we found the co-localized expression of Cxcl14 protein with uNK cells in E13.5 pregnant uterus. Moreover, we used Cxcl14 knockout mice to examine uNK cells in mesometrial lymphoid aggregate of pregnancy (MLAp) and decidua basalis (DB) of E13.5 pregnant uterus and found significantly decreased uNK cells in Cxcl14{sup −/−} pregnant uteri compared with Cxcl14{sup +/−} pregnant uteri. To further explorer the molecular change in MLAp and DB after Cxcl14 knockout, we isolated the MLAp and DB from Cxcl14{sup +/+} and Cxcl14{sup −/−} pregnant uteri and performed microarray analysis. We found many genes were up and down regulated after Cxcl14 knockout. In conclusion, our results suggested the important function of Cxcl14 in uNK cells and the proper level of Cxcl14 protein were required to recruit NK cells to pregnant uterus.

    Full Text Available Background: There is limited information on population-based cancer survival data in Latin America.Objetive: To obtain estimates of survival for some cancers recognized as a public health priority in Colombia using data from the Cancer Registry of Cali for 1995-2004.Methods: All cancer cases for residents of Cali were included for the following sites: breast (3,984, cervix uteri (2,469, prostate (3,999, stomach (3,442 and lung (2,170.  Five-year relative survival estimates were calculated using the approach described by Estève.Results: Five-year relative survival was 79% in patients with prostate cancer and 68% and 60% in women with breast or cervix uteri cancer, respectively. The cure fraction was 6% in subjects with lung cancer and 15% in those with stomach cancer. The probability of dying from breast or prostate cancer in people in the lower socio-economic strata (SES was 1.8 and  2.6  times greater,  respectively,  when compared to  upper SES, p <0.001. Excess mortality associated with cancer was independent of age in prostate or breast cancer.  After adjusting for age, sex and SES, the risk of dying from breast, cervix uteri, prostate and lung cancer during the 2000-2004 period decreased 19%, 13%, 48% and 16%, respectively, when compared with the period of 1995-1999. There was no change in the prognosis for patients with stomach cancer.Conclusions: Survival for some kinds of cancer improved through the 1995-2004 period, however health care programs for cancer patients in Cali are inequitable. People from lower SES are the most vulnerable and the least likely to survive.

    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.

    Background: Uterine synechiae or Asherman's syndrome is a condition that can cause infertility. The present experimental study was designed to establish the rabbit as an animal model for human Asherman's syndrome using the endometrial curettage. Methods: In an experimental study, female adult rabbits (n=18) were randomly divided into intact and ovariectomized groups. One third of caudal part of both uteri was submitted to traumatic endometrial curettage. One group was simultaneously ovariectomized. The intact rabbits were artificially induced ovulation during 10 days after surgery. One third of cranial part of both uteri was selected as the control. Synechiae occurring, luminal area/total area (LA/TA), endometrial area/total area (EA/TA), myometrial and perimetrial area/total area (MPA/TA), endometrial area/uterine wall area (EA/UWA), and myometrial and perimetrial area/uterine wall area (MPA/UWA) ratios of both uteri in six subdivided groups (n=6) were analysed in curetted and intact control parts. On days 15, 30 and 45 following surgery by two-way ANOVA and LSD test (p<0.05). Results: Histopathologic findings showed significant epithelial damage together with significant inflammatory reaction in the intact curettage group. The LA/TA ratios of the intact curettage group on days 15 and 45 were more than the intact control group on day 15. The EA/TA ratio of the intact curettage group on day 30 was less than the intact control group on day 30. Conclusion: Uterine fibrosis was observed in intact curettage group, and this modified animal model showed a pathogenesis condition similar to intrauterine adhesions observed in human. PMID:26962478

  10. Formation of chambers in the bovine uterus during early pregnancy. A comparison between morphological, ultrasonic and nuclear magnetic resonance findings

    International Nuclear Information System (INIS)

    Formation of chambers in the bovine uterus during early pregnancy A comparison between morphological, ultrasonic and nuclear magnetic resonance findings In the bovine, the uterus shows prominent circular folds during early pregnancy. These folds protrude into the lumen nearly at right angles to the uterine wall and, reaching a height of about 2–3 cm in some cases, often reach the center of the uterine lumen. Thus the uterus becomes apparently divided into a number of pocket-like chambers. Endometrial folds are usually found in the pregnant as well as the contralateral uterine horn. Intra-uterine features can be well demonstrated on exenterated bovine uteri without injuring the organ by means of nuclear magnetic resonance imaging with a high resolutive performance. This technique was used to examine the uteri of 4 heifers on day 26, 28, 32 and 55 of pregnancy, respectively. The 3-dimensional imaging of these uteri demonstrated the presence of crescent-shaped folds usually at right angles to the long axis of the uterine horn. These endometrial folds explain why the allantochorionic vesicle cannot be demonstrated in toto by transrectal sonography during early pregnancy, apparently being subdivided by the protrusions from the uterine wall. It has been found that the uterus is characterized by 2–3 echo-weak compartments around day 25 of pregnancy and by about 4–6 by day 30. The number may yet increase with progressing pregnancy. Histological sections out of the wall of the pregnant and the contralateral uterine horn have revealed that the folds are composed mainly of the endometrium (Tunica mucosa) and the circular muscle (Stratum circulare)

  11. Genetic deletion of Cxcl14 in mice alters uterine NK cells

    International Nuclear Information System (INIS)

    Highlights: •We first examined the expression of Cxcl14 in MLAp and DB of uterus. •We found the uNK cells in MLAp and decidua express Cxcl14. •In Cxcl14−/− placenta, we found significantly decreased uNK cells. •We first performed microarray to compare the gene expression in MLAp and DB. -- Abstract: The uterine natural killer cells (uNK cells) are the major immune cells in pregnant uterus and the number of uNK cells is dramatically increased during placentation and embryo development. The uNK cells are necessary for the immune tolerance, cytokine secretion and angiogenesis of placenta. Former studies indicated that the population expansion of uNK cells was accomplished through recruitment of NK cell precursors from the spleen and bone marrow, but not proliferation of NK cells. However, the necessary molecules within this process were little understood. Here in our study, we found the co-localized expression of Cxcl14 protein with uNK cells in E13.5 pregnant uterus. Moreover, we used Cxcl14 knockout mice to examine uNK cells in mesometrial lymphoid aggregate of pregnancy (MLAp) and decidua basalis (DB) of E13.5 pregnant uterus and found significantly decreased uNK cells in Cxcl14−/− pregnant uteri compared with Cxcl14+/− pregnant uteri. To further explorer the molecular change in MLAp and DB after Cxcl14 knockout, we isolated the MLAp and DB from Cxcl14+/+ and Cxcl14−/− pregnant uteri and performed microarray analysis. We found many genes were up and down regulated after Cxcl14 knockout. In conclusion, our results suggested the important function of Cxcl14 in uNK cells and the proper level of Cxcl14 protein were required to recruit NK cells to pregnant uterus

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

    Full Text Available Ovarian hemangiomas are rare tumors. Most of them are asymptomatic and of the cavernous type. The ovaries have a rich vascular supply and the rarity of vascular tumors in the ovary is therefore surprising. Although often found incidentally during the surgery, these lesions may rarely be associated with systemic manifestations. Here, we report two cases of cavernous ovarian hemangiomas. One was accompanied by with an endometrial carcinoma in a patient who presented with postmenopausal bleeding, and the other was found incidentally during the histopathological examination of the hysterectomy and bilateral salphingo-oophorectomy specimen that was performed for leiomyoma uteri.

    AIM:To study the effects of low doses of hydrochloride tetracycline (Tc) on bone metabolism and uterus in the ovariectomized (Ova) rats. METHODS:Forty 3-month-old rats were randomly divided into 5 groups: sham group, Ova group, Tc1 group (1.2mg·kg-1·d-1), Tc2 group (4.8mg·kg-1·d-1), and estrone group (1.48 mg·kg-1·d-1),oral fed for 3 months. The proximal tibia metaphyses were processed undecalcified for quantitative bone histomorphometry and the soft tissues were processed in paraffin for pathological observation. RESULTS: Placebo-treated (lactose) Ova rats were characterized by trabecular area (TA) decreasing and their architecture worsening compared with sham controls, and bone resorption was over formation with high bone turnover. The uteri were atrophy. (2)In estrone-treated group, TA and trabecular numbers were significantly increased and the trabecular separation decreased vs Ova group. Estrone slowed down Ova-inducing bone high turnover. But the size, weight, and the endometrium of the uteri in this group were increased vs Ova group. (3) TA was increased in both Tc1 and Tc2 groups compared with Ova rats. Tc maintained bone formation indices almost at Ova level, and only decreased mineral apposition rate (MAR) in Tc1 group, and declined bone resorption perimeter. The uteri and the cell of liver and kidney almost maintained at Ova level; Tc2 decreased labeling perimeter and increased MAR in comparison with Tc1 group. The uteri were atrophy, whose size maintained at Ova level; yellow labeling was not found in bone with these doses of Tc, while yellow labeling could be seen with the doses of 30mg·kg-1·d-1 of Tc for bone marker. CONCLUSION:The two doses of Tc have similar effects on preventing bone loss in Ova rats while the bone formation and uterus are not affected. However, Tc2 does not have more effects on increasing bone mass, Tc2 causes less mild damages to the liver and kidneys.

    Pyometra, the purulent inflammation of the uterus, is a common uterine disease of bitches that has potentially life-threatening consequences. The opportunistic bacterial infection of the uterus often progresses into the serious systemic inflammatory response syndrome. In a previous study, we characterized epithelial foam cells in the canine endometrial surface occurring in metestrus, and we regularly observed pronounced epithelial foam-cell formations in pyometra-affected uteri. Therefore, it was assumed that the mechanism behind lipid droplet accumulation in surface epithelial cells might even increase bacterial binding capacity and promote pyometra development. Lipid droplet accumulation in epithelial cells is accomplished via specialized lipid receptors called scavenger receptors (SR). Scavenger receptor class B type 1 (SR-B1) is an important receptor for lipid accumulation in diverse cell types, but it is also a strong binding partner for bacteria, and thereby enhances bacterial adhesion and clinical signs of systemic inflammatory response syndrome. In the present study, after the isolation of metestrous surface epithelial cells from canine uteri by laser capture microdissection, SR-B1 was identified at the messenger RNA (mRNA) level by quantitative real time polymerase chain reaction and also at the protein level by means of immunohistochemistry. In pyometra-affected uteri, SR-B1 mRNA expression was higher than that in the healthy control samples, and SR-B1 protein was expressed in the surface and crypt epithelial cells. Furthermore, to understand the physiological role of SR-B1 expression in the metestrus surface epithelial cells, we investigated its expression in the epithelial cells of the glandular chambers of canine placenta in different stages of gestation because these cells are also characterized by lipid droplet accumulation. SR-B1 was present in the placental epithelial cells of the glandular chambers from 25 to 30 and 45 to 50 days of gestation

    Full Text Available Background. Complete androgen insensitivity syndrome is a rare syndrome in which the uterus is absent and testes rather than ovaries are present. Patients usually visit a gynecologist due to primary amenorrhea. Case. A forty-eight-year-old woman with lower abdominal pain and anamnesis of uterus agenesis was operated on due to bilateral cystic masses. A 5 × 3 × 1.2 cm left adnexal cyst revealed the presence of a serous cyst with a hypoplastic ductus deferens. A smaller cyst of the right adnexa revealed immature testis tissue with Leydig-cell hyperplasia. After karyotype and hormonal examinations, laparoscopic gonadectomy was performed. Conclusion. Attention should be paid in all cyst-removing operations in cases of uterus agenesis, due to the high incidence of malignancy. Not of less importance is the issue of informing the patient in the most appropriate way.

    Mucoepidermoid carcinoma is a malignant epithelial neoplasm comprising mucous, intermediate and epidermoid cells, arising mainly in salivary gland. It is extremely uncommon in ocular region, where it can arise in conjunctiva, lacrimal gland or lacrimal sac. The index case is being presented for its rarity and for highlighting the importance of meticulous sampling for correct diagnosis. A 68-year-old female presented with complaints of ulceration over right lower eyelid for 3 years. She underwent a local surgical excision 2 years ago after which she was asymptomatic for the following 1 year. Histopathological examination of excised specimen showed features of mucoepidermoid carcinoma. Mucoepidermoid carcinoma in ocular adnexa may be difficult to differentiate from its close mimickers like basal, squamous, sebaceous cell carcinoma and apocrine carcinoma. Meticulous sampling, judicious use of special stains and immunohistochemistry are pivotal in establishing the diagnosis. PMID:26881601

    Eye and adnexal involvement in epidermolysis bullosa can range from symptoms of mild irritation resulting from conjunctival involvement to severe cicatrization of the ocular surface and adnexa. We describe a unique case of granulation tissue in the eyelid margin and conjunctiva in a patient with junctional epidermolysis bullosa. The eyelid granulation tissue resembled granulomas that seen in laryngo-onycho-cutaneous syndrome, which is caused by a mutation in an isoform of the LAMA3 gene, LAMA3a. On investigation, our patient had a combination of a unique mutation in LAMA3 and the mutation I17N in LAMA3a, providing further evidence that laryngo-onycho-cutaneous syndrome is a variant of junctional EB.

    Full Text Available Thelaziasis is an Arthropod-born disease of the eye and adnexa caused by Thelazia callipaeda, a nematode parasite transmitted by drosophilid flies to carnivores and humans. Because of its distribution mainly confined to South Asian countries and Russia, it is commonly known as Oriental Eye worm. It is often under-reported and not been given its due clinical importance. We report first case of human Thelaziasis from Hassan District, Karnataka. Five creamy-white, translucent worms were removed from the conjunctival sac of a 74-year-old male patient. Based on morphological characters, the worms were identified as nematodes belonging to the genus Thelazia and speciation was confirmed by CDC, Atlanta as callipaeda. Rarity of the disease and its ability to cause both extra and intraocular manifestations leading to ocular morbidity is the reason for presenting this case. From the available data, this is the first case report from Karnataka, India.

Ophthalmomyiasis varies in severity, ranging from simple irritation to complete destruction of the orbit. The condition is often misdiagnosed as an acute conjunctivitis. Globally, so far, most cases have been reported from rural areas. Here, we present 2 case reports. Both patients belonged to an urban area. The larvae were successfully removed, and both cases are being followed. These cases show that this infection is probably more common in urban areas than reported.

    Full Text Available Purpose. External ophthalmomyiasis (EO is caused by infesting larvae belonging to various species of flies. Most documented cases result from sheep (Oestrus ovis and Russian (Rhinoestrus purpureus botfly larvae, but we recently discovered a rare case of EO caused by flesh fly (Sarcophaga argyrostoma larvae. Here, we report the case of a patient with EO who had been hospitalized and sedated for 1 week because of unrelated pneumonia. Methods. Case report. Results. A total of 32 larvae were removed from the adnexae of both eyes. Larvae identification was confirmed through DNA analysis. Treatment with topical tobramycin resulted in complete resolution of EO. Conclusion. EO can be caused by S. argyrostoma, and the elderly and debilitated may require extra ocular protection against flies during sedation.

    Full Text Available A 16-year-old girl presented with primary amenorrhea and excess hair growth on her body and face for the last three years, along with pain and a mass in her lower abdomen for last one year. Examination revealed hirsutism and other virilizing features, with an irregular mass in the lower abdomen corresponding to 16 weeks′gestation. Serum testosterone was 320 ng / dl and ultrasonogram of the pelvis revealed a solid mass of 5 × 4 cm in the left adnexa. Suspecting it to be a virilizing tumor of the left ovary, the patient was subjected to staging laparotomy, which revealed stage 1a ovarian involvement amenable to surgical resection alone. Histopathological examination confirmed the diagnosis of granulosa cell tumor of the ovary. Postoperatively the serum testosterone returned to 40 ng / dl and her menstrual cycle started after two months of surgery.

    Full Text Available Malignant transformation of endometriosis has been extensively described in the literature. However, extragonadal endometrioid adenocarcinoma, either de novo or arising from malignant transformation of endometriosis, is rare. The present case report describes a patient with endometrioid adenocarcinoma on the serous surface of the small intestine. A 25- year-old female with no history of endometriosis was referred to our hospital with an intrapelvic tumor. An internal examination, ultrasound, and magnetic resonance imaging revealed a round mass approximately 80 mm in diameter; however, identification of the affected organ was difficult. Because we could not rule out malignancy based on the non-specific radiologic findings, laparotomy was performed. A mass with ileal adhesions was detected intraoperatively. In addition, the uterus and bilateral adnexa appeared normal. The tumor was resected with part of the ileum. Histopathology confirmed a diagnosis of endometrioid adenocarcinoma originating from the serous surface of the small intestine.

    Clinical presentations associated with vitamin A deficiency persist in poor regions globally with the same clinical features as those described centuries ago. However, new forms of vitamin A deficiency affecting the eyes, which have become widespread, as a result of modern societal habits are of increasing concern. Ophthalmic conditions related to vitamin A deficiency require the combined attention of ophthalmologists, pediatricians, internists, dermatologists, and nutritionists due to their potential severity and the diversity of causes. As the eyes and their adnexa are particularly sensitive to vitamin A deficiency and excess, ocular disturbances are often early indicators of vitamin A imbalance. The present review describes the clinical manifestations of hypovitaminosis A with an emphasis on so-called modern dietary disorders and multidisciplinary treatment approaches. The present review also discusses the relationship between retinoic acid therapy and dry eye disease. PMID:26840172

  1. Ruptured Heterotopic Tubal Pregnancy for a Patient with a History of Segmental Salpingectomy from Ectopic Pregnancy: A Case Report

    International Nuclear Information System (INIS)

    Heterotopic pregnancy refers to the simultaneous development of an intrauterine pregnancy and an extrauterine pregnancy. We experienced a case of a ruptured heterotopic pregnancy for a patient with a history of a right segmental salpingectomy from an ectopic pregnancy. The 30-year-old patient with amenorrhea for six weeks complained of lower abdominal pain with hypovolemic shock. Transabdominal ultrasonography showed diffuse hemoperitoneum with a structure similar to an ectatic tube or a deformed cyst with no echogenic double ring or peripheral hypervascularity in the right adnexa and an intrauterine gestational sac. We considered a ruptured corpus luteum cyst as an ultrasonographic finding and found a ruptured tubal mass in the right salpinx and hemoperitoneum through an emergency laparotomy. We performed a right salpingectomy, and the histopathologic report confirmed ectopic pregnancy.

    BACKGROUND Struma ovarii is a rare ovarian teratoma with non-specific clinical presentation that can mimic malignancy, especially when combined with the presence of ascites. Since the surgical procedures performed for benign and malignant tumors are quite different, pre-operative differential diagnosis is key. In this case report we compare the levels of biomarkers CA 125 and HE4 in the differential diagnosis of a suspicious ovarian tumor. CASE REPORT A 75-year-old woman with a palpable mass at the left adnexa, ascites, and high levels of CA 125, underwent a subtotal abdominal hysterectomy and bilateral salpingo-oophorectomy. Histology reported benign struma ovarii. CONCLUSIONS Even though transvaginal ultrasound and CA 125 levels suggested malignancy, HE4 measurements correctly diagnosed benignity. PMID:27381498

    Full Text Available A post menopausal lady presented with lump lower abdomen and bleeding per vaginum. USG revealed diffuse enlargement of the uterus. On hysterectomy, a grossly enlarged uterus with cystic left ovary were found. Hysterectomy was done and uterus with bilateral adnexa submitted for histopathological examination. Microscopic examination of the body of uterus revealed sheets of small lymphoid cells were found to replace the endo- and myo-metrium. These cells have small nuclei with clumped chromatin, and no prominence of nucleoli. They are not forming lymphoid follicles or germinal centers. Similar lymphoid cells were also found in the left ovary admixed with ovarian stroma. On IHC these cells were found to be CD45, CD20, CD23 positive, and negative for CD3 , CK and SMA. The case is diagnosed as a primary small lymphocytic lymphoma of uterus with left ovarian spread.

    Full Text Available Expectant management for tubal heterotopic pregnancy could be considered as a successful option in a symptom-free patient where the ectopic embryo has a limited craniocaudal length with no cardiac activity. We report the obstetric outcome after expectant management for a right tubal heterotopic pregnancy. Heterotopic pregnancy was first recognized at 6 weeks gestation in a 32-year-old salpingectomized woman with an 8-year history of subfertility who conceived after in utero transfer of three embryos obtained by in vitro fertilization. Expectant management and close ultrasonographic and clinical monitoring were done. The intrauterine pregnancy proceeded unremarkably. A cesarean section was performed for breech presentation, and it allowed the delivery of a healthy 2260-g male infant. The examination of the adnexa showed a pre-rupture of the right fallopian tube.

    Full Text Available Rhabdomyomatous mesenchymal hamartoma (RMH is a rare congenital lesion of the dermis and soft tissue, first described in 1986 as a striated muscle hamartoma. It has been reported under various names: striated muscle hamartoma, congenital midline hamartoma, hamartoma of cutaneous adnexa and mesenchyme. Etiology of this lesion is unknown; it has been hypothesized that be due to an abnormal migration of mesodermal stem cells during embryiogenesis or to right genetic defects. Patients with RMH occasionally have other congenital defects. RMH usually presents as a polypoid or papular cutaneous lesion that ranges in size from a few millimeters to 1-2 cm and occurs in areas where there is a superficial striated muscle, as the nose, chin, periorbital and anterior neck areas. Here we report a case of RMH in a 2-year-old child presenting with a congenital polypoid mass on the nasal skin.

    2014-04-01

    Full Text Available Sporotrichosis associated with exposure to domestic cats is hyperendemic in Rio de Janeiro, Brazil. A review of the clinical records at our institute revealed four patients with clinical signs of dacryocystitis and a positive conjunctival culture for Sporothrix who were diagnosed with Sporothrix dacryocystitis. Three patients were children (< 13 years of age and one patient was an adult. Two patients reported contact with a cat that had sporotrichosis. Dacryocystitis was associated with nodular, ulcerated lesions on the face of one patient and with granulomatous conjunctivitis in two patients; however, this condition manifested as an isolated disease in another patient. All of the patients were cured of the fungal infections, but three patients had chronic dacryocystitis and one patient developed a cutaneous fistula. Sporotrichosis is usually a benign disease, but may cause severe complications when the eye and the adnexa are affected. Physicians, especially ophthalmologists in endemic areas, should be aware of the ophthalmological manifestations and complications of sporotrichosis.

    Objective: To collect, preserve and document primary ethnopharmacological information on common natural remedies (NRs) used by the Chinese community to treat and/or manage common diseases in Mauritius, a tropical multicultural island in the Indian Ocean. Methods: Face-to-face interviews were carried out with 52 key Chinese informants using a semi-structured questionnaire. Quantitative ethnobotanical indices, namely, the informant consensus factor (FIC), the use value, the fidelity level, the index of agreement on remedies and the relative importance were calculated.Results:constituted the exploited flora and fauna by the Chinese community. Based on the FIC the main categories of plants used were employed against injury and poisons due to external causes (FIC=0.97), diseases of the respiratory system (FIC=0.96), diseases of the eye and adnexa (FIC=0.95), undefined pains or illness (FIC=0.95), diseases during the postpartum period, diseases of the digestive system and diseases of the skin and subcutaneous tissue (FIC=0.94 each). For zootherapy, diseases of the circulatory system, diseases of the eye and adnexa, diseases of the skin and subcutaneous tissue and endocrine, nutritional and metabolic diseases had total consensus Plants (61) and animal species (17), belonging to 43 and 9 families respectively, (FIC=1.00). Conclusions: It was found that the Chinese community of Mauritius still relies, to a great extent, on NRs which need to be preserved and used sustainably. Nonetheless, further research is needed to probe the possible active constituents that could be the basis of an evidence-based investigation to discover new drugs.

    Purpose: Low-dose radiation has become increasingly used in the management of indolent non-Hodgkin lymphoma (NHL), but has not been studied specifically for cases of ocular adnexal involvement. The objective of this study is to investigate the effectiveness of low-dose radiation in the treatment of NHL of the ocular adnexa. Methods and Materials: We reviewed the records of 20 NHL patients with 27 sites of ocular adnexal involvement treated with low-dose radiation consisting of 2 successive fractions of 2 Gy at our institution between 2005 and 2011. The primary endpoint of this study is freedom from local relapse (FFLR). Results: At a median follow-up time of 26 months (range 7-92), the overall response rate for the 27 treated sites was 96%, with a complete response (CR) rate of 85% (n=23) and a partial response rate of 11% (n=3). Among all treated sites with CR, the 2-year FFLR was 100%, with no in-treatment field relapses. The 2-year freedom from regional relapse rate was 96% with 1 case of relapse within the ipsilateral orbit (outside of the treatment field). This patient underwent additional treatment with low-dose radiation of 4 Gy to the area of relapse achieving a CR and no evidence of disease at an additional 42 months of follow-up. Orbital radiation was well tolerated with only mild acute side effects (dry eye, conjunctivitis, transient periorbital edema) in 30% of treated sites without any reports of long-term toxicity. Conclusions: Low-dose radiation with 2 Gy × 2 is effective and well tolerated in the treatment of indolent NHL of the ocular adnexa with high response rates and durable local control with the option of reirradiation in the case of locoregional relapse.

    Purpose: To define a male and female pelvic normal tissue contouring atlas for Radiation Therapy Oncology Group (RTOG) trials. Methods and Materials: One male pelvis computed tomography (CT) data set and one female pelvis CT data set were shared via the Image-Guided Therapy QA Center. A total of 16 radiation oncologists participated. The following organs at risk were contoured in both CT sets: anus, anorectum, rectum (gastrointestinal and genitourinary definitions), bowel NOS (not otherwise specified), small bowel, large bowel, and proximal femurs. The following were contoured in the male set only: bladder, prostate, seminal vesicles, and penile bulb. The following were contoured in the female set only: uterus, cervix, and ovaries. A computer program used the binomial distribution to generate 95% group consensus contours. These contours and definitions were then reviewed by the group and modified. Results: The panel achieved consensus definitions for pelvic normal tissue contouring in RTOG trials with these standardized names: Rectum, AnoRectum, SmallBowel, Colon, BowelBag, Bladder, UteroCervix, Adnexa{sub R}, Adnexa{sub L}, Prostate, SeminalVesc, PenileBulb, Femur{sub R}, and Femur{sub L}. Two additional normal structures whose purpose is to serve as targets in anal and rectal cancer were defined: AnoRectumSig and Mesorectum. Detailed target volume contouring guidelines and images are discussed. Conclusions: Consensus guidelines for pelvic normal tissue contouring were reached and are available as a CT image atlas on the RTOG Web site. This will allow uniformity in defining normal tissues for clinical trials delivering pelvic radiation and will facilitate future normal tissue complication research.

    Full Text Available Aim: To evaluate the clinical profile and management of 46 XX Congenital Adrenal Hyperplasia (CAH patients presenting with severe virilization and assigned a male gender. Materials and Methods: Of 173 children diagnosed with CAH at the Pediatric Intersex Clinic since 1980, seven children with CAH presented late with severe virilization and were reared as males. All of them were assigned the male sex with removal of the female adnexa. Six were treated with male genitoplasty. Appropriate hormonal supplementation was offered after puberty. Results: The mean age at presentation was 14.2 years (7 - 21. Six patients had presented after puberty, only one at seven years of age. Staged male genitoplasty comprising of chordee correction, male urethroplasty, and bilateral testicular prosthesis was performed. The female adnexa (uterus, ovaries, most of the upper vagina, and the fallopian tubes were removed. The mental makeup was masculine in six and bigender in one. Bilateral mastectomy was performed at puberty in all. Hormonal treatment comprised of glucocorticoids and testosterone. Six patients were comfortable with the outcome of the masculinizing genitoplasty. One had a short-sized phallus. One had repeated attacks of urinary tract infection arising from the retained lower vaginal pouch. Social adjustments were good in all, except in one who had a bigender mental makeup. Conclusion: CAH patients with severe virilization presenting late and reared as males are extremely rare. However, the assigned gender can be retained adequately as males, meeting the socioeconomic compulsions of the society. The results are satisfactory following appropriate surgical procedures and hormonal supplementation.

    Mesenchymal stem cells (MSCs) offer promise as therapeutic aid in the repair of tendon and ligament injuries in race horses. Fetal adnexa is considered as an ideal source of MSCs due to many advantages, including non-invasive nature of isolation procedures and availability of large tissue mass for harvesting the cells. However, MSCs isolated from equine fetal adnexa have not been fully characterized due to lack of species-specific markers. Therefore, this study was carried out to isolate MSCs from equine umbilical cord blood (UCB) and characterize them using cross-reactive markers. The plastic-adherent cells could be isolated from 13 out of 20 (65 %) UCB samples. The UCB derived cells proliferated till passage 20 with average cell doubling time of 46.40 ± 2.86 h. These cells expressed mesenchymal surface markers but did not express haematopoietic/leucocytic markers by RT-PCR and immunocytochemistry. The phenotypic expression of CD29, CD44, CD73 and CD90 was shown by 96.36 ± 1.28, 93.40 ± 0.70, 73.23 ± 1.29 and 46.75 ± 3.95 % cells, respectively in flow cytometry, whereas, reactivity against the haematopoietic antigens CD34 and CD45 was observed only in 2.4 ± 0.20 and 0.1 ± 0.0 % of cells, respectively. Osteogenic and chondrogenic differentiation could be achieved using established methods, whereas the optimum adipogenic differentiation was achieved after supplementing media with 15 % rabbit serum and 20 ng/ml of recombinant human insulin. In this study, we optimized methodology for isolation, cultural characterization, differentiation and immunophenotyping of MSCs from equine UCB. Protocols and markers used in this study can be employed for unequivocal characterization of equine MSCs. PMID:25487085

    Ectopic pregnancy after hysterectomy is a rare but potentially life-threatening condition requiring prompt diagnosis to prevent the increased mortality associated with rupture. Twenty-seven cases of late post-hysterectomy ectopic pregnancy reported in the English literature since 1918 were reviewed and analysed for presenting symptoms, missed diagnosis rate at initial presentation, location of ectopic and rupture rate at diagnosis. The presenting symptoms were found to be non-specific. The diagnosis in this population is twice more likely to be missed than in women with intact uteri. The rupture rate is 63%, compared with 37% in women with intact uteri. The majority of late post-hysterectomy ectopic pregnancies (62%) were located in the fallopian tubes. Because of the potential risk of mortality, emergency physicians should always consider the possibility of ectopic pregnancy in childbearing women whose surgical history includes hysterectomy without oophorectomy. Evaluation of abdominal pain in this population should include a pregnancy test to ensure prompt diagnosis when the possibility of pregnancy exists clinically. PMID:22672163

  16. Autoradiographic localization of epidermal growth factor receptors to all major uterine cell types

    International Nuclear Information System (INIS)

    We have recently studied the structure and function of the uterine epidermal growth factor (EGF) receptor, its hormonal regulation, and its possible role in estrogen-induced uterine DNA synthesis. Since the uterus is composed of multiple cell types, we sought, in the work reported here, to localize EGF binding in this organ by autoradiography. Prior to the actual autoradiography, we performed a companion series of experiments to insure that EGF binding to uterine tissue in situ represented a true receptor interaction. Uteri from immature female rats were incubated in vitro with 125I-EGF at 25 degrees C. Tissue binding was maximal within 120 min and remained constant for at least an additional 120 min. This binding of labeled EGF was largely abolished by excess unlabeled EGF but not by other growth factors, indicating that binding was to specific receptors. The binding of 125I-EGF was saturable and reached a plateau at 4-8 nM; specific binding was half-maximal at 1-2 nM EGF. In situ cross-linking studies revealed that 125I-EGF was bound predominantly to a 170,000 MW EGF receptor similar to that seen in isolated uterine membranes. Incubation of uteri with 125I-EGF followed by autoradiography revealed binding to epithelial cells, stroma, and myometrium. These results provide evidence for the presence of specific EGF receptors in all major uterine cell types of the immature rat

    Six pregnant Standardbred mares aged between 6 and 14 years were gavaged with 50 g or 100 g of suspended emulsified whole Processionary caterpillars (Ochrogaster lunifer) for 5 days during 2 experiments undertaken to study the etiology of equine amnionitis and fetal loss (EAFL). The 6 treated mares and 1 untreated mare were between 128 and 252 days gestation. Mare 1 (untreated) was euthanized on day 5 of the treatment period, while the treated mares were euthanized on days 2, 4, 8, 10, 12, and 24 days from their first treatment. Caterpillar setae were not found in the untreated mare. Setal fragments were present in all regions of the gastrointestinal tracts in all treated mares, the uteri and mesenteric lymph nodes of 5 mares, and the liver of 4 mares. Acute gastroenteritis of varying severity was present in all treated mares, and 5 of 6 mares had acute colitis and endometritis. Focal hyperplastic serositis was found in the duodenum, cecum, dorsal colon, and uteri of various mares occasionally with embedded setal fragments. Setal invasion of the mucosa evoked a range of lesions including superficial erosion to deep ulceration. Inflammation in deeper tissues ranged from unapparent to neutrophilic (microabscesses), eosinophilic, or mononuclear (microgranulomas). The finding of setal fragments within the uterus of experimental mares suggests that direct migration of setal fragments acting as a bacterial vector is a likely mechanism for the bacterial abortions that characterize equine amnionitis and fetal loss.

    An oncopathological state assessment was conducted among adults, children and teenagers in Aktobe region for 2004-2013. Overall the burden of mortality was in the range of 94.8-100.2 per 100,000 population, without any obvious trend over time. Ranking by pathology, the highest incidences among women were registered for breast cancer (5.8-8.4), cervix uteri (2.9-4.6), ovary (2.4-3.6) and corpus uteri, stomach, esophagus, without any marked change over time except for a slight rise in cervical cancer rates. In males, the first place in rank was trachea, bronchus and lung, followed by stomach and esophagus, which are followed by bladder, lymphoid and hematopoietic tissues pathology. Agian no clear trends were apparent over time. In children, main localizations in cancer incidence blood (acute lymphocytic leukemia, lymphosarcoma, acute myeloid leukemia, Hodgkin's disease), brain and central nervous system, bones and articular cartilages, kidneys, and eye and it's appendages, in both sexes. Similarly, in young adults, the major percentage was in blood and lymphatic tissues (acute myeloid leukemia, acute lymphocytic leukemia, Hodgkin's disease) a significant percentage accruing to lymphosarcoma, lymphoma, other myeloid leukemia and hematological malignancies as well as tumors of brain and central nervous system, bones and articular cartilages. This initial survey provides the basis for more detailed investigation of cancer epidemiology in Aktobe, Kazakhstan. PMID:26745053

  19. Clinical study on hysteromyoma treated with uterine artery embolization

    International Nuclear Information System (INIS)

    Objective: To study the therapeutic effect, side-effect and safety of uterine artery embolization of hysteromyoma with pinyangmycin and lipiodol emulsion. Methods: Embolization carried out selectively through uterine artery with pinyangmycin and lipiodol emulsion of 158 hysteromyoma was followed up for 3-18 months with observation of the size of hysteromyoma, the change of corpus uteri and the degree of reactions. Results: All cases were embolized successfully including 150 cases of bilateral and 8 cases of unilateral uterine arterial embolization. The appearance of uterine arteries showed obvious arterial enlargement with spiral hypervasculature, tumor staining and prolonged opacification. Six patients underwent hysteroectomy 1 week after the embolization. The specimens demonstrated flaky necrosis with small bloody specks under pathologic examination. The alleviation rate of symptoms were 90.5% with recovery of normal menstrual cycle as 89.4%. The compressive symptoms of hypogastric pain and abdominal distention disappeared in 91.3%. The reduction in size of hysteromyoma and corpus uteri were 80% and 48% on average respectively. Conclusion: The primary results demonstrates that uterine artery embolization of hysteromyoma is safe and effective, with low complication rate and more advantage over surgical approach. (authors)

    rates of the Danish population were used for calculation of standardized incidence ratios (SIRs). Time at risk was from diagnosis of breast cancer+1 year until death or through 2002. Risk for all second primary cancers combined was increased, SIR=1.04 (95% confidence interval 0.99-1.08). Sites with...... significantly elevated risks included corpus uteri (SIR=1.23), ovary (1.39), soft tissues (2.24), acute leukaemia (2.02), and sites potentially inducible by breast cancer radiotherapy combined (1.11). For irradiated patients compared to non-irradiated the risk was increased for all sited combined, radiotherapy......-related sites, colon and soft tissues. Tamoxifen treated had, compared to non-treated, elevated risk for cancer of corpus uteri (SIR=1.83 vs 1.04).

    1979-01-01

    The morphology of the pars intramuralis of the fallopian tube has been histological examined in 500 uteri which were exstirpated in the Department of Gynaecology and Obstetrics of the University of Kiel in the years of 1972 to 1973. It was found that the interstitial pars of the endometrium changes regularly during the menstrual cycle. In the same way the endometrium in the interstitial part of the tubal canal suffers from an atrophy if patients were treated with gestagens. The adenomatous hyperplasie or the polypes of the endometrium which are often found near the utero-tubal junction are to be considered as the matrix of the carcinoma of the endometrium; continuous changes between the adenomatous hyperplasie and the carcinoma of the endometrium can be observed. The frequency of precancers near the utero-tubal junction underlines the demand for an accurate curettage in this region of the cavum uteri. The histological examination of the region of the utero-tubal junction after the extirpation of the uterus is absolutely necessary and has to be generally to be asked for. PMID:433496

    Full Text Available Aim of the study was to estimate the incidence of unexpected premalignant gynecological lesions in women undergoing vaginal hysterectomy for utero-vaginal prolapse. Material and methods : Eighty women with asymptomatic utero-vaginal prolapse were included in this prospective study for vaginal hysterectomy after preoperative preparation and after written informed consent. Women included in this study were screened preoperatively by high vaginal swab, Pap smear, endometrial biopsy and trans-vaginal ultrasound. Surgically removed uteri and ovaries were sent for histopathological examination. Results of histopathological examination as gold standard were compared with conventional gynecological screening methods. Results : Histopathological examination of surgically removed uteri and ovaries after vaginal hysterectomy for uterovaginal prolapse showed abnormal findings in 61.25% (49/80 of studied cases (10 chronic cervicitis; 20 cervical intra-epithelial neoplasia-1 [CIN-1]; 5 CIN-2; 2 CIN-3; 10 simple endometrial hyperplasia without atypia and 2 simple serous ovarian cyst. Also, histopathological examination showed premalignant changes in 33.75% (27/80 of studied cases (20 CIN-1; 5 CIN-2 and 2 CIN-3, which mean 50% sensitivity of pre-operative Pap smear to detect premalignant cervical changes. Conclusions : Asymptomatic women with utero-vaginal prolapse may have associated premalignant lesions which may not be detected by conventional screening methods, and this should be explained preoperatively for women undergoing surgery, especially if conservative management was considered.

  3. Computer simulation of fractionated radiotherapy: Further results and their relevance to percutaneous irradiation and brachytherapy

    International Nuclear Information System (INIS)

    Basing on previous papers, the present communication considers the simulation of the radiotherapeutic treatments of glioblastoma multiforme, rectum adenocarcinoma, and gynaecological tumors of cervix uteri (squamous and adenocarcinoma) in spheroid culture. Starting with a single tumor cell in a nutrient medium and after the corresponding growth of the tumor spheroids, varying irradiation schemes are applied to the carcinoma and are compared with regard to tumor kill effectivity using the LQ-model. The two first-mentioned carcinoma are exposed to the dose fractionation schemes standard-, super-, hyperfractionation, and weekly high single dose. The result is that hyperfractionation (3x1.5 Gy/day) and weekly high single dose (1x6 Gy/week) yield the most effective tumor cell kill. The weekly high single dose may be realized by some different irradiation techniques, e.g. stereotactic irradiation or interstitial high dose rate brachytherapy. The treatment of the cervix uteri tumors is performed by a combined therapy form (high dose rate brachytherapy and percutaneous irradition). A comparing simulation of two typical regimens yield a nearly equivalent tumor kill effectivity. By the integration of in vitro tumor growth and clinical treatment schemes in a computer model, the possibility is made available to test the effectivity of variable regimens with the help of computer experiments.

  4. Formation of autohemolysins in radiotherapy of oncologic patients

    International Nuclear Information System (INIS)

    Formation of autohemolysins before and after radiotherapy in 51 patients with mammary gland cancer and 70 patients with cervix uteri carcinoma has been studied. Telegammatherapy of different dose rates has been used: ''ROCUS'' installation - 113.6 R/min, GUT-Co-400M-19.1 R/min. Besides the patients were subjected to X-ray therapy at 59.2 R/min dose rate at a RUM-17 installation. In 33 patients with mammary gland cancer and 47 patients with cervix utery carcinoma after the above radiotherapy the number of plaque-forming cells has increased as compared with the initial data. The reaction for detecting plaque-forming cells in blood of oncologic patients in the dynamics of radiotherapy can be recommended as a test determining the organism response to radiation effect. The appearance of the large number of autohemolysins at a certain stage of radiotherapy can be an indication for patient prescription of drugs reducing its organism autosensibilization

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

    Late radiation injuries of the intestine are frequent after radiation therapy of malignant tumors of female genitalia and some other tumors in which the intestine gets into the irradiation field. On the basis of the analysis of 80 patients with late radiation injuries of intestine which developed at remote terms after radiation therapy of cervix uteri cancer and corpus uteri (65 patients) and other tumors, peculiarities of the clinical course and treatment of radiation enterocolitis, rectosigmoidites, and rectites are discussed. In 39 patients, these injuries were concomitant with late radiation injuries of the skin and subcutaneous soft tissues. The clinical course of radiation injuries of the intestine was defined by the character of the pathological process in the intestine and was more sharply marked in patients suffering from radiation enterocolites. It was established that one of the pathogenetic mechanisms of late radiation injuries of the intestine was a disorder of the absorption function of the intestine. Local treatment of radiation injuries of the intestine should be combined with a general one the important component of which is a parenteral diet.

    Endometritis constitutes a major problem in managing broodmares. The histological occurrence of polymorphonuclear neutrophils (PMNs) in the stratum compactum of the endometrium is accepted as the reference standard to diagnose endometritis in mares. The objective of this study was to determine the distribution of PMNs within different sampling locations of the uterus by cytological examinations and to compare it with PMN numbers in endometrial biopsies of the corresponding location. Cytological and endometrial samples were obtained from 37 uteri within 2 ± 1 hours after slaughter through small incisions from five different, predefined locations of each uterus. The cytological samples were smeared on microscopic slides, stained, and classified as negative (endometritis. Histologically, the numbers of PMNs were counted in three high power fields by an experienced pathologist and classified as positive for this type of endometritis if ≥5 PMNs occurred in three high power fields (×40 magnification). The biopsies were also evaluated for lymphoplasmacellular endometritis, periglandular fibrosis (endometrosis), and angiosclerosis. The prevalence of positive cytological and histological samples was 14.6% and 17.8%, respectively. A fair agreement between the two diagnostic methods could be detected (k = 0.29; P < 0.01). The numbers of PMNs differed between the sampling locations, resulting in positive and negative locations within a positive scored uterus, in both cytologically positive scored uteri (8/10) and histologically positive scored uteri (13/14). No significant differences were found in PMN numbers in the different locations, either the cytological (P = 0.78) or histological (P = 0.79) examination. Additionally, no significant differences were observed in the assessment of endometrosis (P = 0.96) and angiosclerosis (P = 0.67) within the locations. In conclusion, PMN numbers of a cytological examination of the endometrium showed fair agreement to the occurrence

    Organotins (OTs) are environmental contaminants used as biocides in antifouling paints that have been shown to be endocrine disrupters. However, studies evaluating the effects of OTs accumulated in seafood (LNI) on reproductive health are particularly sparse. This study demonstrates that LNI leads to impairment in the reproductive tract of female rats, as the estrous cycle development, as well as for ovary and uterus morphology. Rats were treated with LNI, and their reproductive morphophysiology was assessed. Morphophysiological abnormalities, such as irregular estrous cycles, abnormal ovarian follicular development and ovarian collagen deposition, were observed in LNI rats. An increase in luminal epithelia and ERα expression was observed in the LNI uteri. Together, these data provide in vivo evidence that LNI are toxic for reproductive morphophysiology, which may be associated with risks to reproductive function. PMID:26050607

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

    The mortality caused by malignant tumors in the town of Chapaevsk, characterized by increased level of dioxins in the environment, is statistically higher than the expected values. For men the relative risk of general morbidity is 1.9 and mortality, 1.8; for lung cancer: morbidity, 3.3 and mortality 3.1; for urogenital cancer: morbidity, 3.6 and mortality, 2.6; for gastric cancer: morbidity 1.9 and mortality, 1.7. In women the morbidity and mortality due to breast cancer (relative risks 1.9 and 2.1, respectively) and cancer of the cervix uteri (relative risks 2.1 and 1.8, respectively) are increased. Changes in the reproductive health of residents of this town are as follows: high incidence of spontaneous abortions, appearance of small-for-date babies, and genital disorders in body (cryptorchidism, phimosis, hypospadia, delayed sexual development).

    Full Text Available Morphometric studies of uteri, ovary weights, and follicle diameters were carried out to investigate possible methodological applications. Size and anatomical appearance of the uterus varied with age and phase in the estrous cycle, both in parous and nulliparous females. The uterus thus may provide valuable information on reproductive status for known-aged animals. Weight of ovaries increased in young, but declined in old females, showing significant covariance with body weight in young and prime ages. Ovary weights increased from low levels shortly after parturition to a maximum towards the end of the gestation period. Ovaries containing a corpus luteum were heavier than those without. Compared to ovary weights, mean diameter of largest ovarian follicle varied in an opposite pattern during the yearly cycle. Maximum follicle diameter was largest in non-ovulated females. Weight of ovaries and follicle size appear to be of limited value as criteria in analysis of reproductive status and performance.

    Full Text Available Adenomyotic cysts of the uterus are extremely rare and this case report is to document an adenomyotic cyst of the uterus associated with pelvic pain. A 27-year old nulliparous patient admitted to the hospital with the complaint of dysmenorrhea, dyspareunia and pain in the right pelvic region for the last 3 months. Transvaginal ultrasonographic examination revealed a 50 × 36 mm intramural cystic lesion on the right region of the corpus uteri. Hysteroscopic examination showed that it did not deteriorate the endometrial cavity. During laparatomy dissection of the uterine wall revealed 5 cm cystic lesion that was excised circumferentially protecting the surrounding myometrial tissue. The definitive pathology report came out as adenomyotic tissue. Imaging techniques are critical in differential diagnosis of adenomyotic cysts and to choose the appropriate intervention. Medical therapy or surgical intervention like excision of the cyst or hysterectomy may be the choices of treatment. J Clin Exp Invest 2014; 5 (1: 100-102

  15. The molecular mechanisms of offspring effects from obese pregnancy.

    2013-01-01

    The incidence of obesity, increased weight gain and the popularity of high-fat \\/ high-sugar diets are seriously impacting upon the global population. Billions of individuals are affected, and although diet and lifestyle are of paramount importance to the development of adult obesity, compelling evidence is emerging which suggests that maternal obesity and related disorders may be passed on to the next generation by non-genetic means. The processes acting within the uteri of obese mothers may permanently predispose offspring to a diverse plethora of diseases ranging from obesity and diabetes to psychiatric disorders. This review aims to summarise some of the molecular mechanisms and active processes currently known about maternal obesity and its effect on foetal and neonatal physiology and metabolism. Complex and multifactorial networks of molecules are intertwined and culminate in a pathologically synergistic manner to cause disruption and disorganisation of foetal physiology. This altered phenotype may potentiate the cycle of intergenerational transmission of obesity and related disorders.

    The increasing use of nanomaterials has raised concerns about their potential risks to human health. Recent studies have shown that nanoparticles can cross the placenta barrier in pregnant mice and cause neurotoxicity in their offspring, but a more detailed understanding of the effects of nanoparticles on pregnant animals remains elusive. Here, we show that silica and titanium dioxide nanoparticles with diameters of 70 nm and 35 nm, respectively, can cause pregnancy complications when injected intravenously into pregnant mice. The silica and titanium dioxide nanoparticles were found in the placenta, fetal liver and fetal brain. Mice treated with these nanoparticles had smaller uteri and smaller fetuses than untreated controls. Fullerene molecules and larger (300 and 1,000 nm) silica particles did not induce these complications. These detrimental effects are linked to structural and functional abnormalities in the placenta on the maternal side, and are abolished when the surfaces of the silica nanoparticles are modified with carboxyl and amine groups.

  19. The role of the environment in Ukraine after Chernobyl accident and the genetic component in cancer development in female reproductive system

    International Nuclear Information System (INIS)

    An increase in breast cancer and tumors of reproductive organs was revealed both in a group of women from the regions which are subject to radiation control after the Chernobyl NPP accident and a wider group of Ukrainian female population non-restricted to the above region. Geographical distribution of morbidity is demonstrated. Both genetic and environmental factors are proved to play a part in the susceptibility to development of breast and corpus uteri cancers. The contribution of each of the above factors is assessed.Chromosomal instability was revealed in endometrium cancer patients, even more pronounced in the individuals with a tumor development history aggregated in families. The need for further investigation of development of cancer against genetic background is underlined

    To determine the effect of abdominal and/or pelvic irradiation for gynecological malignancies on the later development of hyperthyroidism, 1,884 medical records of the patients diagnoses as carcinomas of cervix and corpus uteri, and of ovary were reviewed. Among 1,269 patients with radiation therapy, 5 patients developed hyperthyroidism after irradiation to the abdomen and/or pelvis. This is a statistically significant increase when compared with an epidemiological study. Radiation dose to the thyroid was estimated to be 30 to 200 rads. Two other patients who were irradiated to the nose or supraclavicular region in addition to the abdomen also developed hyperthyroidism. However, none of 581 patients without radiation therapy became hyperthyroid. The results indicate that radiation therapy for treatment of gynecological malignancy gives a significant radiation exposure with an increase in the incidence of subsequent hyperthyroidism.

  1. Peculiarities of disorders in reproductive system and hormonal sensitivity of tumor associated with neoplasm,s which correspond to the syndrome of hormone-related cancers

    International Nuclear Information System (INIS)

    Blood-serum levels of gonadotrophins and estradiol were assayed alongside with those of estradiol and progesterone receptors in the tissue of tumors of the breast, uterus, ovary and large bowel to establish general regularities of reproductive homeostasis in patients. The study was based on the assumption that risk of secondary tumor development is considerable in a patient who bears one of said malignancies. The effect of estrogen hormones was shown to be one of general causes of tumorigenesis. This is corroborated by enhanced hyperestrinism observed in cases of carcinoma of the corpus uteri as well as by certain data pointing to a reliable correlation between estrogen-stimulated synthesis of progesterone receptors and prognosis in patients with tumors of the breast, uterus and ovary. No estrogen dependence, however, was registered in patients with tumors of the bowel. Pathogenetic features shared by tumors of the large bowel and those of the reproductive system should probably be accounted for by disorders in metabolism

  2. Killing of preimplantation mouse embryos by main ingredients of cleansers AS and LAS

    International Nuclear Information System (INIS)

    When main ingredients of cleansers, alcohol sulfate (AS) and linear alkylbenzene sulfonate (LAS), were applied to the dorsal skin of pregnant JCL:ICR mice during preimplantation period, significant numbers of embryos collected from the oviducts and uteri on day 3 showed severe deformity or remained at the morula stage. Most of abnormal embryos were fragmented or remained at the 1-8 cell stages, and they were either dead or dying. Similar results were observed with commercially obtained kitchen detergent and hair shampoo. Fertilized eggs may be specifically sensitive to synthetic detergents. Very low doses of X-rays also induced significant yields of abnormal embryos. Major difference between X-rays and detergents was that X-ray-induced abnormality appeared at the morula or blastocyst stage, while detergent-induced one did at the earlier stages. (Auth.)

    The effects of whole-body inhalation exposures to 1,3-butadiene on the reproductive system was evaluated. The results of dominant lethality in CD-1 male mice that were exposed to 1,3-butadiene are described. Subsequent to exposure, males were mated with two unexposed females. Mating was continued for 8 weeks with replacement of two females each week. Gravid uteri were removed, and the total number, position and status of implantations were determined. The mice were weighed prior to exposure and at 0, 1, 2, 3, 4, 5, 6, 7, and 8 weeks after exposure and at sacrifice. The animals were observed for mortality, morbidity and signs of toxicity throughout the study. 19 refs., 5 figs., 9 tabs.

There are excep- tional difficulties of making the diagnosis of epithelial damages due to the incomplete reproducibility of cytological abnormal ities and the low informative value of a histological study of scrapes from the cervical canal. To avoid hypodiagnosis, it is justifiable to prefer human papillomavirus testing (Hybrid Capture 2 (HC2 to repeat smears for the choice of a management tactic.

    Full Text Available This paper describes a case of an unusual recovery of adult Ascaridia galli in hen’s egg. Several data are available on this occurrence but it appears to be the first case described in Italy. The worm was identified as an adult female, 6.8 cm in length, with three trilobed lips, cervical narrow alae, oesophagus club-shaped without posterior bulb, vulva near the middle of body, with gravid uteri containing a large number of eggs. The presence of Ascaridia galli in hen’s eggs cannot be considered as hazard for public health but may be cause of a potential consumer complaint. Moreover it is a sign of presence of ascaridiosis, parasitosis that still produces economic losses in modern poultry production system.

    The prevalence of müllerian malformations is 1 in 200, or 0.5%. A third of the anomalies are septate, a third bicornuate uteri, 10% arcuate uterus, 10% didelphis and unicornuate uterus, and pregnancy rates. In contrast, surgical repair of a bicornuate uterus requires an abdominal metroplasty. This should only be performed if the patient has recurrent fetal loss due to the uterine structural defect. In a unicornuate uterus it is most important to determine if there is a second uterine horn that can cause cyclic pain if it has functioning endometrium. The only surgical option in these cases is to remove the rudimentary uterus with endometrium and hematometra, respectively. PMID:21437824

    Recent years’ advance in sequencing technology has resulted in extensive new knowledge of the microbial ecology of different environments. We used the technology to investigate the causality of endometritis, which is an inflammation in the inner lining of the uterus affecting up to 20% of dairy...... cows in Denmark post partum. Endometritis is linked to reduced reproductive performance, which is costly for the farmer and often leads to culling of the affected cows. With incomplete knowledge of the bacteria involved, treatment is performed without an option for choosing the best suited...... antimicrobial agent, which may lead to unnecessary antibiotic resistance development. Slaughterhouse samples were analysed in order to obtain information on the uterine microbiota from both cows with endometritis and seemingly healthy cows from a variety of herds.

    The aim of this study was to determine the effectiveness of hyaluronic acid solution in preventing intraperitoneal (IP) adhesions. The study design was prospective, randomized and blinded and involved 83 rats. Measured serosal injury was inflicted using a CO2 laser on the right uterine horn of the rat. Animals randomized to groups 1 and 2 received either 0.4% hyaluronic acid or its diluent phosphate-buffered saline (PBS) intraperitoneally before and after the injury. In groups 3 and 4, the same solutions were used only after the injury. Postoperative adhesions were assessed at second-look laparotomy. Histologic assessment of the fresh laser injury was carried out on uteri pretreated with hyaluronic acid, PBS, or nothing. Pretreatment with hyaluronic acid was associated with a significant reduction in postoperative adhesions and a significantly decreased crater depth. Hyaluronic acid appears to reduce postoperative IP adhesion formation by coating the serosal surfaces and decreasing the extent of initial tissue injury.

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

    M.L. Schulman

    1997-07-01

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

    1990-08-01

    Five N'Dama heifers were superovulated with follicle stimulating hormone (FSH-P or Folltropin) a total of six times each. The superovulations were carried out between ongoing experimental Trypanosoma congolense infections. Twenty-four (80%) of the 30 superovulations had a good ovarian response with 21 (70%) producing an average of 2.7 +/- 0.4 (mean +/- s.e.m.) embryos. The highest embryo production was achieved at the third and fourth superovulation, after which both the number of embryos and their quality declined. The overall pregnancy rate after transfer into Boran (Bos indicus) cow recipients was 50.9%. The uteri of the heifers increased considerably in size throughout the six superovulations which made it difficult to flush some of the animals after the third superovulation. Embryo transfer technology is a useful breeding tool in N'Dama heifers and multiple superovulations can be carried out with success. PMID:2120824

    2006-01-01

    Full Text Available Abstract. The article presents the results of intraperitoneal administration of recombinant rat interferon-α to twenty Wistar rats with experimentally induced endometriosis. The following criteria of treatment efficiency were applied: presence of ectopic endometrium in transplanted segments of cornu uteri, proliferative activity of endometrioid cells, features of vascularization and leucocyte infiltration within endometrial foci. It was shown that local application of interferon-α caused regression of endometrioid epithelial heterotopias in 50 per cent of the cases. If endometrioid epithelium was retained, its proliferative activity did significantly drop under interferon-α application. In all transplants derived from rats treated with interferon-α, the degree of vascularization is reduced, accompanied by increased leucocytic infiltration (due to lymphocytes, along with decreased contents of macrophages within leucocytic infiltrates.

  14. Labeling of receptor ligands with bromine radionuclides. Progress report, March 1, 1981-February 28, 1982

    International Nuclear Information System (INIS)

    In recent years there has been an interest in the use of various radioisotopes of bromine as labels for radiopharmaceuticals. Although radioisotopes of iodine have been used extensively as radiopharmaceutical labels, there are several advantages associated with the use of radiobromine as a label, due primarily to increased stability of bonds to the radiohalide and smaller steric perturbation resulting from substitution of the radiohalide. Methods of attaching radiobromine to receptor ligands with the potential of mapping estrogen receptors in mammary tumors and uteri were studied. Two ligands were studied extensively in vitro and in animal models; preliminary studies were also carried out in humans. To date, the only radioisotope of bromine used was bromine-77. In addition, a series of model compounds were labeled with bromine-77 using a recently described method for rapid bromination; the scope and limitations of this new rapid radiobromination technique were evaluated

    Neuroendocrine tumors (neuroendokrine Tumoren) are rare entities. They can be found in all organs and show substantial biologic heterogeneity depending on involved organ, clinical symptoms and histopathologic morphology. Involvement of organs like larynx, cervix uteri, ovary, gallbladder, liver or kidney is extensively rare. The majority of neuroendokrine Tumoren are found in gastrointestinal tract and lung and are classified as neuroendokrine Tumoren of foregut (stomach, duodenum, pancreas, lung), midgut (jejunum, ileum, appendix, right side of the colon) and hindgut (left side of the colon, rectum). The role of imaging is to localize and delineate the primary tumor and to detect metastases. In the diagnosis of neuroendokrine Tumoren radiologic techniques like computed tomography (CT) and magnetic resonance imaging (MRI) are applied. In certain cases nuclear medicine techniques like somatostatin receptor scintigraphy (SRS) and positron emission tomography (PET) using radioactively labelled somatostatin analogues are used. The present article reviews characteristic imaging findings of neuroendokrine Tumoren of the gastrointestinal tract. (orig.)

    Anetoderma is a cutaneous disorder characterized by loss of dermal elastic tissue resulting in papules from herniation of subcutaneous tissue or circumscribed areas of atrophic, wrinkled skin. Familial leiomyomatosis cutis et uteri (Reed syndrome) is an autosomal dominant disorder characterized by cutaneous and uterine leiomyomas. We report a 23-year-old male with Reed syndrome who presented with asymptomatic pearly white, atrophic, flaccid papules on the upper back and shoulder that depressed when palpated. Pathologic examination showed an unremarkable epidermis and central loss of dermal elastin, bordered by clumped elastin, as revealed with an elastin stain. The correlation of clinical and pathologic findings indicated a diagnosis of anetoderma arising in a patient with Reed syndrome. PMID:25950901

    Objective: To make interaction between morphine and naloxone in the rat model of PCOS, we evidenced the opioid receptors involvement in this efficacy. Methods:A total of 48 female animals (Wistar rats weighing 200-250 g) were kept diestrous before experimental procedure began. They were grouped in single L-arginine (50 mg/kg, i.p., once a day for 9 days), naloxone (0.4 mg/kg, i.p., once daily for 9 days), morphine (5 mg/kg, i.p., once a day for 9 days), and naloxone (0.4 mg/kg) pre-treated to L-arginine (50 mg/kg), morphine (5 mg/kg) pre-treated to L-arginine, morphine pre-treated to the collective naloxone-L-arginine. Control group solely received saline (1 mL/kg, once daily for 9 days). At the end of the treatment period all animals were surgically studied. The rats’ ovaries and uteri were examined both biometrically and pathologically. Results:The ovaries of rats treated with L-arginine showed polycystic characteristics and their uteri illustrated inflammation changes to the controls. The samples obtained from rats pre-treated with naloxone revealed a decrease in sign of inflammation compaired with L-arginine received speciments, the signs got worse in the presence of the morphine. Conclusion:Aspect of rat reproductive system may be linked with the cystic characteristic of ovary. This study involves opioid receptors in the naloxone efficacy on reproductive agents of rat with polycystic aspect.

    Common congenital embryonic remnants of the canine female genital tract are Gartner cysts originating from mesonephric duct remnants. They can increase in size and lead to adverse effects in fertility and health. In the present study, three cases of mesonephric remnants in bitches were analysed. The mesonephric remnants featured an inner lining endometrium comprising surface epithelium, glands and stroma. This ectopic endometrium was further characterized by immunohistochemistry (oestrogen and progesterone receptors, proliferation activity, cytokeratin, alpha smooth muscle actin, and vimentin) and lectin histochemistry compared with normal uterine endometrium. Furthermore, hypertrophic cells at the serosal site of the uteri were detected and analysed in the same way compared with normal serosa. The ectopic endometrium of case no. 2 mesonephric remnant was comparable with normal endometrium whereas in nos 1 and 3 uteri the ectopic endometrium was reduced in thickness. In all mesonephric remnants, surface and glandular epithelial cells of the ectopic endometrium gave positive immunoreactions for cytokeratin, oestrogen and progesterone receptors and showed lectin-binding patterns comparable with normal endometrium. Some of the stromal cells of the ectopic endometria were smooth muscle actin and vimentin positive. Mitotic activity of the ectopic endometria was comparable with normal endometria. Hypertrophic epithelial cells of the serosal side showed positive reactions to anti-oestrogen receptor and anti-cytokeratin immunohistochemistry as well as lectin binding patterns and mitotic activity comparable with the normal canine serosa. The present study is the first considerable immunohistochemical characterization of canine mesonephric remnants and discusses the appearance of ectopic endometrium in mesonephric remnants.

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

    International Nuclear Information System (INIS)

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

  1. Canine uterine bacterial infection induces upregulation of proteolysis-related genes and downregulation of homeobox and zinc finger factors.

    Directory of Open Access Journals (Sweden)

    Ragnvi Hagman

    Full Text Available BACKGROUND: Bacterial infection with the severe complication of sepsis is a frequent and serious condition, being a major cause of death worldwide. To cope with the plethora of occurring bacterial infections there is therefore an urgent need to identify molecular mechanisms operating during the host response, in order both to identify potential targets for therapeutic intervention and to identify biomarkers for disease. Here we addressed this issue by studying global gene expression in uteri from female dogs suffering from spontaneously occurring uterine bacterial infection. PRINCIPAL FINDINGS: The analysis showed that almost 800 genes were significantly (p2-fold in the uteri of diseased animals. Among these were numerous chemokine and cytokine genes, as well as genes associated with inflammatory cell extravasation, anti-bacterial action, the complement system and innate immune responses, as well as proteoglycan-associated genes. There was also a striking representation of genes associated with proteolysis. Robust upregulation of immunoglobulin components and genes involved in antigen presentation was also evident, indicating elaboration of a strong adaptive immune response. The bacterial infection was also associated with a significant downregulation of almost 700 genes, of which various homeobox and zinc finger transcription factors were highly represented. CONCLUSIONS/SIGNIFICANCE: Together, these finding outline the molecular patterns involved in bacterial infection of the uterus. The study identified altered expression of numerous genes not previously implicated in bacterial disease, and several of these may be evaluated for potential as biomarkers of disease or as therapeutic targets. Importantly, since humans and dogs show genetic similarity and develop diseases that share many characteristics, the molecular events identified here are likely to reflect the corresponding situation in humans afflicted by similar disease.

    The use of a combined therapy with low doses of estrogens plus antidepressants to treat depression associated to perimenopause could be advantageous. However the use of these combinations is controversial due to several factors, including the time of intervention in relation to menopause onset. This paper analyzes whether time post-OVX influences the antidepressant-like action of a combination of ethynyl-estradiol (EE₂) and citalopram (CIT) in the forced swim test (FST). Middle-aged (15 months old) female Wistar rats were ovariectomized and after one or three weeks treated with EE₂ (1.25, 2.5 or 5.0 µg/rat, s.c.; -48 h) or CIT (1.25, 2.5, 5.0 or 10 mg/kg, i.p./3 injections in 24 h) and tested in the FST. In a second experiment, after one or three weeks of OVX, rats received a combination of an ineffective dose of EE₂ (1.25 µg/rat, s.c., -48 h) plus CIT (2.5 mg/kg, i.p./3 injections in 24 h) and subjected to the FST. Finally, the uteri were removed and weighted to obtain an index of the peripheral effects of EE₂ administration. EE₂ (2.5 or 5.0 µg/rat) reduced immobility after one but not three weeks of OVX. In contrast, no CIT dose reduced immobility at one or three weeks after OVX. When EE₂ (1.25 µg/rat) was combined with CIT (2.5 mg/kg) an antidepressant-like effect was observed at one but not three weeks post-OVX. The weight of the uteri augmented when EE₂ was administrated three weeks after OVX. The data suggest that the time post-OVX is a crucial factor that contributes to observe the antidepressant-like effect of EE₂ alone or in combination with CIT. PMID:27153072

    There is a controversy regarding the effects of the analogues of the gonadotrophin-releasing hormone (GnRH) in radiotherapy. This has led us to study the possible radio-protection of the ovarian function of a GnRH agonist analogue (GnRHa), triptorelin, in adult, female rats (Rattus norvegicus sp.). The effects of the X-irradiation on the oocytes of ovarian primordial follicles, with and without GnRHa treatment, were compared, directly in the female rats (F{sub 0}) with reproductive parameters, and in the somatic cells of the resulting foetuses (F{sub 1}) with cytogenetical parameters. In order to do this, the ovaries and uteri from 82 females were extracted for the reproductive analysis and 236 foetuses were obtained for cytogenetical analysis. The cytogenetical study was based on the data from 22,151 metaphases analysed. The cytogenetical parameters analysed to assess the existence of chromosomal instability were the number of aberrant metaphases (2234) and the number (2854) and type of structural chromosomal aberrations, including gaps and breaks. Concerning the reproductive analysis of the ovaries and the uteri, the parameters analysed were the number of corpora lutea, implantations, implantation losses and foetuses. Triptorelin confers radio-protection of the ovaries in front of chromosomal instability, which is different, with respect to the single and fractioned dose. The cytogenetical analysis shows a general decrease in most of the parameters of the triptorelin-treated groups, with respect to their controls, and some of these differences were considered to be statistically significant. The reproductive analysis indicates that there is also radio-protection by the agonist, although minor to the cytogenetical one. Only some of the analysed parameters show a statistically significant decrease in the triptorelin-treated groups.

  4. Adult health study report 7. noncancer disease incidence in the atomic-bomb survivors, 1958-86 (examination cycles 1-14)

    International Nuclear Information System (INIS)

    Using the longitudinal data of the Adult Health Study (AHS) cohort collected during 1958-86, we examined for the first time the relationship between exposure to ionizing radiation and the incidence of 19 selected nonmalignant disorders. Diagnoses of the diseases were based on general laboratory tests, physical examinations, and histories taken during the biennial AHS examinations. The outcomes were encoded as three-digit International Classification of Diseases codes in the AHS data base, which served as the basis for case ascertainment. Statistically significant excess risk was detected for myoma uteri, chronic hepatitis and liver cirrhosis, and thyroid disease, defined broadly as the presence of one or more of certain noncancerous thyroid conditions. The finding for myoma uteri might be additional evidence indicating that benign tumor growths are possible effects of radiation exposure. An age-at-exposure effect was detected in nonmalignant thyroid disease, with increased risk for those exposed at ages ≤ 20 yr, but not for older persons. Thus, the AHS data also suggest that the thyroid gland in young persons is more radiosensitive not only to the development of thyroid malignancies, as shown in the most recent LSS report on cancer incidence, but also possibly to the development of nonmalignant disorders. Our findings hold independent of the dose effects observed for thyroid malignancies. No significant dose-response relationships were detected in any of our cardiovascular disease endpoints. Our analysis also suggests that new occurrences of lens opacity during 1958-86 are not increased with radiation dose among the AHS participants. Our results emphasize the utility and importance of the AHS in searching for the effects of acute exposure to ionizing radiation in noncancer diseases. (J.P.N.)

    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.

    To evaluate the efficacy and safety of nafarelin before hysterectomy in a prospective placebo-controlled trial, we randomized 188 pre-menopausal women with uterine fibroids (n = 111), menometrorrhagia (n = 58) or pelvic pain (n = 19) to receive either nafarelin (200 micrograms twice daily as a nasal spray) or a placebo for 3 months before abdominal hysterectomy. The data analysis could be performed in 166 women, of whom 107 received nafarelin and 59 a placebo. Nafarelin led to a rise in blood haemoglobin (5.5 g/l) and to a decrease in uterine volume (23.7%). This, however, gave no objective benefit during surgery (similar operative durations and blood losses). The uteri from patients treated with nafarelin (255.5 +/- 12.6 g, mean +/- SD) were significantly lighter (P = 0.029) than those from patients treated with a placebo (346.2 +/- 35.7 g). Histological examination of the fibroids or uteri revealed changes typical for hypo-oestrogenism, but no specific histological pattern could be established. The endometrium was proliferative in 56% and showed mild hyperplastic features in 10% of patients given nafarelin, whereas the respective figures for the placebo group were 41 and 0%. Hot flushes were the most common side-effects, being reported by 61% in the nafarelin group and 35% in the placebo group. Nafarelin can be useful as a pre-surgical adjunct in a patient scheduled for abdominal hysterectomy if there is a need to raise the haemoglobin concentration or to reduce the size of the uterus.

    Full Text Available Tumor benigno de tecido muscular, o piloleiomioma tem origem no músculo eretor do pelo, atingindo ambos os sexos geralmente na terceira década de vida. Apresenta-se como nódulo-pápulas assimétricas nas extremidades, de cor eritêmato-acastanhada e de consistência firme. As lesões, quando múltiplas, podem ser sensíveis ou dolorosas. Sua associação com miomas uterinos, denominada de síndrome de Reed ou leiomiomatose cutis et uteri, é apresentação rara, podendo estar associada a carcinoma de células renais. A abordagem é cirúrgica em casos isolados e medicamentosa se houver sintomas. Relatamos um caso de síndrome de Reed em que se optou por acompanhamento pela ausência de sintomatologia.Piloleiomyoma, a benign smooth-muscle tumor arising from the arrectores pilorum muscles of the skin, affects males and females in the third decade of life. It presents as asymmetrical, reddish-brown nodules or papules with a firm consistency, predominantly located on the limbs. When multiple lesions are present, they may be tender or painful. Their association with uterine fibroids, referred to as Reed syndrome or familial leiomyomatosis cutis et uteri, is rare and may be associated with renal cell carcinoma. The approach consists of surgical excision in cases presenting few lesions and pharmacological treatment if symptomatic. The present paper describes a case of Reed syndrome in which a decision was made to monitor the patient in view of the absence of symptoms.

  8. The GnRH analogue triptorelin confers ovarian radio-protection to adult female rats

    International Nuclear Information System (INIS)

    There is a controversy regarding the effects of the analogues of the gonadotrophin-releasing hormone (GnRH) in radiotherapy. This has led us to study the possible radio-protection of the ovarian function of a GnRH agonist analogue (GnRHa), triptorelin, in adult, female rats (Rattus norvegicus sp.). The effects of the X-irradiation on the oocytes of ovarian primordial follicles, with and without GnRHa treatment, were compared, directly in the female rats (F0) with reproductive parameters, and in the somatic cells of the resulting foetuses (F1) with cytogenetical parameters. In order to do this, the ovaries and uteri from 82 females were extracted for the reproductive analysis and 236 foetuses were obtained for cytogenetical analysis. The cytogenetical study was based on the data from 22,151 metaphases analysed. The cytogenetical parameters analysed to assess the existence of chromosomal instability were the number of aberrant metaphases (2234) and the number (2854) and type of structural chromosomal aberrations, including gaps and breaks. Concerning the reproductive analysis of the ovaries and the uteri, the parameters analysed were the number of corpora lutea, implantations, implantation losses and foetuses. Triptorelin confers radio-protection of the ovaries in front of chromosomal instability, which is different, with respect to the single and fractioned dose. The cytogenetical analysis shows a general decrease in most of the parameters of the triptorelin-treated groups, with respect to their controls, and some of these differences were considered to be statistically significant. The reproductive analysis indicates that there is also radio-protection by the agonist, although minor to the cytogenetical one. Only some of the analysed parameters show a statistically significant decrease in the triptorelin-treated groups.

  9. Molecular Pathogenesis of MALT Lymphoma

    2015-01-01

    Full Text Available Approximately 8% of all non-Hodgkin lymphomas are extranodal marginal zone B cell lymphoma of mucosa associated lymphoid tissue (MALT, also known as MALT lymphoma, which was first described in 1983 by Isaacson and Wright. MALT lymphomas arise at a wide range of different extranodal sites, with the highest frequency in the stomach, followed by lung, ocular adnexa, and thyroid, and with a low percentage in the small intestine. Interestingly, at least 3 different, apparently site-specific, chromosomal translocations and missense and frameshift mutations, all pathway-related genes affecting the NF-κB signal, have been implicated in the development and progression of MALT lymphoma. However, these genetic abnormalities alone are not sufficient for malignant transformation. There is now increasing evidence suggesting that the oncogenic product of translocation cooperates with immunological stimulation in oncogenesis, that is, the association with chronic bacterial infection or autoaggressive process. This review mainly discusses MALT lymphomas in terms of their genetic aberration and association with chronic infections and summarizes recent advances in their molecular pathogenesis.

    Full Text Available Objective. Imperforate hymen represents the extreme in the spectrum of hymenal embryological variations. The archetypal presentation in the adolescent patient is that of cyclical abdominopelvic pain in the presence of amenorrhoea. We reported a rare event of imperforate hymen presenting as a cause of tuboovarian abscess (TOA. Case Study. A 14-year-old girl presented to the emergency department complaining of severe left iliac fossa pain. It was her first episode of heavy bleeding per vagina, and she had a history of cyclical pelvic pain. She was clinically unwell, and an external genital examination demonstrated a partially perforated hymen. A transabdominal ultrasound showed grossly dilated serpiginous fallopian tubes. The upper part of the vagina was filled with homogeneous echogenic substance. Magnetic resonance imaging (MRI demonstrated complex right adnexa mass with bilateral pyo-haemato-salpinges, haematometra, and haematocolpos. In theatre, the imperforate hymen was opened via cruciate incision and blood was drained from the vagina. At laparoscopy, dense purulent material was evacuated prior to an incision and drainage of the persistent right TOA. Conclusion. Ideally identification of imperforate hymen should occur during neonatal examination to prevent symptomatic presentation. Our case highlights the risks of late recognition resulting in the development of sepsis and TOA.

    The comprehensive "one-stop shop" ultrasound evaluation of an infertile woman, performed around cycle days 5 to 9, will reveal abundant information about the anatomy and morphology of the pelvic organs and thereby avoid costly radiation and iodinated contrast exposure. We propose a two-dimensional and three-dimensional ultrasound to examine the appearance and shape of the endometrium, endometrial cavity, myometrium, and junctional zone, to assess for müllerian duct anomalies fibroids, adenomyosis, and polyps. We then evaluate the adnexa with grayscale ultrasound and Doppler, looking for ovarian masses or cysts, and signs of tubal disease. The cul-de-sac is imaged to look for masses, endometriosis, and free fluid. We then push gently on the uterus and ovaries to assess mobility. Lack of free movement of the organs would suggest adhesions or endometriosis. The sonohysterogram then allows for more detailed evaluation of the endometrial cavity, endometrial lining, and any intracavitary lesions. Tubal patency is then assessed during the sonohysterogram in real time by introducing air and saline or contrast and imaging the tubes (HyCoSy). With this single comprehensive ultrasound examination, patients can obtain a reliable, time-efficient, minimally invasive infertility evaluation in their own clinician's office at significantly less cost and without radiation.

    With the increasing popularity of assisted reproductive technology (ART), radiologists are more likely to encounter associated complications, especially in an emergency setting. These complications include ovarian hyperstimulation syndrome (OHSS), ovarian torsion, and ectopic and heterotopic pregnancy. OHSS occurs following ovulation induction or ovarian stimulation and manifests with bilateral ovarian enlargement by multiple cysts, third-spacing of fluids, and clinical findings ranging from gastrointestinal discomfort to life-threatening renal failure and coagulopathy. Enlarged hyperstimulated ovaries are at risk for torsion. Clinical symptoms are often nonspecific, and ovarian torsion should be suspected and excluded in any female patient undergoing infertility treatment who presents with severe abdominal pain. The most consistent imaging finding is asymmetric enlargement of the twisted ovary. There is also an increased risk for ectopic pregnancy following ART, with a relative increased risk for rarer and more lethal forms, including interstitial and cervical ectopic pregnancies. Heterotopic pregnancy refers to simultaneous intrauterine and ectopic pregnancies and has an incidence of 1%-3% in ART patients. Careful evaluation of the adnexa is critical in this patient population, even when an intrauterine pregnancy has been confirmed. Ultrasonography is the first-line imaging modality for the evaluation of complications of ART, although nonspecific symptoms may sometimes lead to cross-sectional imaging being performed. Familiarity with the multimodality imaging appearance of these entities will allow accurate and timely diagnosis and help avert potentially fatal consequences. PMID:23322839

    Full Text Available Parag Suresh Mahajan, Nazeer Ahamad, Sheik Akbar Hussain Department of Radiology, Al-Khor Hospital, Hamad Medical Corporation, Doha, Qatar Abstract: An autoamputated wandering calcified ovary (AWCO is an extremely rare cause of abdominal calcification in the pediatric population. We present the magnetic resonance imaging (MRI features of AWCO in a child. To our knowledge, the MRI features of AWCO have not been previously described in the published literature. Our case report indicates that the MRI findings are characteristic in the diagnosis of an AWCO and can completely obviate the need for invasive procedures in this mostly benign disease. An AWCO should be considered in all cases of mobile calcific opacities on radiographs in female patients. We advise that MRI be conducted in all suspected cases of AWCO for accurate and noninvasive diagnosis, and regular follow-up should be performed with ultrasound. The findings in our case report have the potential to change the course of investigations and management in suspected cases.

    Full Text Available Struma ovarii, which is classified as benign or malignant, is a mature ovarian teratoma consisting mainly of the thyroid tissue. Here, we present the case of malign struma ovarii in a patient with right adnexal mass. In a 53-year-old female, who was referred to our hospital with pelvic pain, abdominopelvic imaging revealed a cystic lesion measuring 15x14 cm in diameter in the right adnexa. Total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed. Microscopic evaluation revealed a 1.5x1x0.5 cm papillary carcinoma focus in frozen sections of the mural nodule which was observed inside the cyst. Following the surgical procedure, the patient’s TSH levels were kept low by thyroxine treatment, and it was decided to follow the patient by annual measurement of thyroglobulin levels and pelvic imaging. There is not a common consensus on optimal treatment of malignant struma ovarii. Treatment options depend on cases or case series. Turk Jem 2015; 19: 112-114

    Full Text Available Background: Vitiligo is a common depigmented skin disorder that is caused by selective destruction of melanocytes. It is generally accepted that the main function of melanin resides in the protection of skin cells against the deleterious effect of ultraviolet rays (UVRs. Association of vitiligo and skin cancer has been a subject of controversy. Occurrence of skin cancer in long-lasting vitiligo is rare despite multiple evidences of DNA damage in vitiliginous skin. Aim: To detect the expression of P53 and Mdm2 proteins in both depigmented and normally pigmented skin of vitiligo patients and to compare it to control subjects suffering from nonmelanoma skin cancer (NMSC. Materials and Methods: Thirty-four patients with vitiligo and 30 age and sex-matched patients with nodulo-ulcerative basal cell carcinoma (BCC as a control group were selected. Both patients and control subjects had outdoor occupations. Skin biopsies were taken from each case and control subjects. Histopathological examination of Hematoxylin and eosin-stained sections was done. Expression of P53 and Mdm2 proteins were examined immunohistochemically. Results: Both P53 and Mdm2 were strongly expressed in depigmented as well as normally pigmented skin of vitiligo patients. This expression involved the epidermis, skin adnexa and blood vessels with significant differences between cases and controls. Conclusions: The overexpression of P53 and Mdm2 proteins in both normally pigmented and depigmented skin of patients with vitiligo could contribute to the decreased occurrence of actinic damage and NMSC in these patients.

    Full Text Available Eye diseases in childhood are important causes of medical consultation and it affects learning ability, adjustment in school and personality. To determine the pattern of ocular morbidity a cross-sectional observational study was conducted among 714 children, attending Ophthalmology department at a tertiary eye care center in Kolkata, West Bengal. All the children less than 15 years of age, attending in Unit II outpatient department were selected by complete enumeration method for duration of one year (January-December 2010. Distribution of association was analyzed by Chi-square test and difference between two proportions was calculated by z test for proportions. The common ocular morbidity were refractive errors (23.67% followed by allergic conjunctivitis (17.23%, infection of the eye and adnexa (15.13%, ocular trauma (12.74%, and congenital eye diseases (13.59%. Majority of ocular morbidity is treatable and need early attention through eye screening cum intervention program beginning right from the childhood.

    Full Text Available Actinomycotic infection of the female genital tract is rare. Actinomycosis is a chronic suppurative granulomatous infection that is characterized by formation of abscesses, multiple draining sinuses and appearance of tangled mycelial masses or granules in the discharges and tissue sections. 2 cases of tubo-ovarian actinomycosis are reported. The 1st case presented clinical with gastrointestinal symptoms and a ventral scar hernia following an operation for a non-healing abdominal wound 6 months earlier. The 2nd case sought medical attention for backache and leucorrhea of 4 years′ duration. Exploratory laparotomy in the 1st case revealed tubo-ovarian masses; the vermiform appendix was not traceable. The uterine cavity in the 2nd case harbored a wooden stick. Direct extension from established ileocacal actinomycosis was believed to involve the female genital adnexae in the past. Association of tubo-ovarian actinomycosis with the presence of a foreign body in the female genital tract has been reported sporadically in the literature, yet an increase in the incidence may be expected because of the frequent use of intrauterine contraceptive devices in recent times. It is suggested that in women presenting clinically with vague abdominal symptoms, backache and discharge, actinomycosis should be considered and ruled out with the help of cytologic and proper microbial culture methods. Once the diagnosis is established, the infection can be treated with good results with penicillin.

    2016-07-01

    Lymphomas of the ocular adnexa and intraocular tissue include a wide range of lymphoproliferative neoplastic disorders. They are predominantly extranodal non-Hodgkin lymphomas (NHL). The World Health Organization (WHO) classification of lymphoid neoplasm and individual morphological, immunophenotypical, and molecular genetic features, indicate that they may be divided into B-cell (approximately 80 % of all NHL) and T-cell lymphomas (approximately 10-20 % of all NHL). The most common forms of ocular NHL are extranodal marginal zone lymphoma (EMZL) of the mucosa-associated lymphoid tissue (MALT-type), follicular lymphoma (FL), diffuse large B-cell lymphoma, and mantel cell lymphoma. The clinical signs and symptoms are usually very unspecific and depend on the location, size, and extent of the underlying lymphoma subtype. Typical low grade lymphomas have an indolent clinical course and often remain unrecognized for many years. On the other hand, high grade NHLs, such as DLBCL or MCL, are frequently aggressive, with rapid tumour growth and poor prognosis, despite early detection. Histopathology is still the gold standard in the diagnosis of ocular lymphomas. Basic understanding of the principal pathophysiological and clinical aspects of the development and progression of orbital and ocular lymphomas seems to be mandatory for optimal diagnosis and treatment and for improving survival and prognosis. Both residents in training and board certified ophthalmologists should be aware of these problems. PMID:27468099

    We conducted this prospective cohort study to standardize our laparoscopic technique of excision of posterior deep infiltrating endometriosis (DIE) nodules, according to their size, location, and geometry, including 36 patients who were grouped, according to principal pelvic expansion of the nodule, into groups with central (group 1) and lateral (group 2) lesions, and according to nodule size, into ≤2 cm (group A) and >2 cm (group B) lesions, respectively. In cases of group 1 the following operative steps were more frequently performed compared to those of group 2: suspension of the rectosigmoid, colpectomy, and placement of bowel wall reinforcement sutures. The opposite was true regarding suspension of the adnexa, systematic ureteric dissection, and removal of the diseased pelvic peritoneum. When grouping patients according to nodule size, almost all of the examined parameters were more frequently applied to patients of group B: adnexal suspension, suspension of the rectosigmoid, systematic ureteric dissection, division of uterine vein, colpectomy, and placement of bowel wall reinforcement sutures. Nodule size was the single most important determinant of duration of surgery. In conclusion, during the building-up of one's learning curve of laparoscopic excision of posterior DIE nodules, technique standardization is very important to avoid complications. PMID:24579050

    Canine aural cholesteatoma is an epidermoid cyst that forms in the middle ear cavity as a rare complication of otitis media but the aetiopathogenesis remains controversial. In the present study, 13 cases of canine aural cholesteatoma were investigated histologically and immunohistochemically and compared with cases of chronic otitis. The immunohistochemical investigation was performed using the following monoclonal antibodies: anti-cytokeratins (CK) 14, 16, 8/18, and 19, and anti-Ki67. The proliferative indexes (PIs) of cholesteatomata and otitis epithelium were calculated as the percentage of Ki67 positive nuclei/total nuclei. Histologically, the cholesteatomata were composed of a hyperplastic, hyperkeratotic epithelium (matrix) resting on a fibrous perimatrix, infiltrated by inflammatory cells and devoid of cutaneous adnexa. Immunohistochemically, the cholesteatoma epithelium was CK14- and CK16-positive, and CK8/18- and CK19-negative. A similar pattern of CK expression was found in otitis externa. In otitis media, ciliated epithelium stained CK8/18- and CK19-positive in all layers, CK14-positive in the basal layers, and CK16-negative. The mean PIs in cholesteatomata and otitides were 18.8 and 17.8, respectively. The immunohistochemical pattern of CK expression in cholesteatomata, when compared with chronic otitis, was suggestive of hyperproliferative epithelium, but its origin could not be demonstrated. Comparable PI values were obtained in cholesteatoma and in chronic otitis, which confirmed that Ki67 is a valuable indicator of a hyperproliferative state, but not a predictor of aggressiveness.

    Couceiro, Rita

    2015-06-01

    Full Text Available Objective: To report an unusual case of systemic non-Hodgkin lymphoma (NHL with repeated relapse in the lacrimal glands, in spite of complete remission for several years after treatment.Methods: A 78-year-old male with small lymphocytic B cell NHL, stage IV disease (lung invasion, was submitted to surgery and chemotherapy in 2001, with complete remission of the disease. In 2003 he developed a nodular lesion in the right lacrimal fossa. Pathology results revealed a local relapse of NHL. Radiation and chemotherapy were initiated and complete remission was again achieved. In 2012 the patient developed a new nodular lesion located in the left lacrimal fossa, resulting in diplopia, ptosis and proptosis of the left eye. Orbital computerized tomography (CT, ocular ultrasound and incisional biopsy were performed.Results: Orbital CT revealed a lesion infiltrating the left lacrimal gland and encircling the globe. Biopsy results confirmed a local relapse of B cell NHL. The patient was submitted to local radiation therapy with progressive resolution of ptosis, proptosis and diplopia. Response to treatment was monitored with ocular ultrasound. Conclusions: Patients with NHL diagnosis should be immediately investigated if ophthalmic or orbital symptoms develop. NHL extension to the orbit and adnexa is infrequent (5% of NHL cases but may occur at any stage of the disease, including as a relapse site. In such cases, radiation and chemotherapy achieve good results, inducing long periods of remission.

    We report the case of a patient with unresectable progressive advanced rectal cancer, who has been able to maintain a good quality of life because of combination therapy, including chemoradiotherapy. A 52-year-old woman was diagnosed with progressive locally advanced rectal cancer and invasion of the adnexa of the uterus and the left ureter. No distant metastasis was detected. Colostomy was performed, followed by chemoradiotherapy combined with S-1; then, mFOLFOX6 +bevacizumab (BV) therapy was administered. Aggravation of bilateral hydronephrosis was detected upon completion of 2 courses of treatment, and therefore, percutaneous nephrostomy of the right kidney was performed. After the patient underwent 20 courses of treatment, imaging showed a reduction in the size of the lesion, and the CEA level returned to normal. Later, remission was sustained by sLV5FU2+BV therapy and oral administration of S-1. As a result, we were able to remove the nephrostomy tube from the right kidney in February 2011. Four years after initiation of the treatment, the patient has shown no indication of recurrence. PMID:23267933

    Full Text Available Abstract Malignant mixed Müllerian tumor is a rare malignancy of the genital tract and extremely uncommon in extragenital sites. This report describes a case of malignant mixed Müllerian tumor arising in the lower peritoneum of a 72-year-old female patient. The patient presented with ascites, lower abdominal mass and pleural effusion. The serum level of CA125 was elevated. At operation a diffuse carcinosis associated with tumor mass measuring 20 × 15 × 10 cm in the vesicouterine and Duglas' pouch were found. The uterus and the adnexa were unremarkable. Histopathology revealed a typical malignant mixed Müllerian tumor, heterologous type. The epithelial component was positive for cytokeratin 7 and vimentin whereas the mesenchymal component was positive for Vimentin, S100 and focally for CK7. The histogenesis of this tumor arising from the peritoneum is still speculative. Based on the previous reports and the immunohistochemical analysis of our case, we believe that this is a monoclonal tumor with carcinoma being the "precursor" element. Nevertheless, further molecular and genetic evidence is needed to support such a conclusion.

    Full Text Available OBJECTIVE: We report on a series of female patients with transitional cell carcinoma of the bladder who underwent extraperitoneal retrograde radical cystectomy sparing the female reproductive organs with neobladder creation. MATERIALS AND METHODS: 14 female patients between the ages of 45 and 72 years who underwent gynecologic-tract sparing cystectomy (GTSC with neobladder between 1997 and 2002 were retrospectively reviewed. Our surgical technique is also described. Radical cystectomy is accomplished by a retrograde method sparing the uterus, adnexa, vagina and distal urethra. An orthotopic neobladder was constructed using small bowel or sigmoid colon, brought extraperitoneally, and anastomosed to the distal urethra. RESULTS: Operating time ranged from 4.5 to six hours with a mean of 5.3 hours. Ten patients were able to void satisfactorily while four required self-catheterization for complete emptying of the bladder. Seven patients were continent day and night and another 7 reported varying degrees of daytime and nighttime incontinence. One patient died of metastases and another of pelvic recurrence. There were no urethral recurrences. Patient satisfaction with the procedure was high. CONCLUSIONS: Gynecologic-tract sparing cystectomy with orthotopic neobladder is a viable alternative in female patients with muscle invasive traditional cell carcinoma of the bladder, providing oncological safety with improved quality of life. Our extraperitoneal technique, which is an extension of our successful experience with retrograde extraperitoneal radical cystectomy in men, minimizes intraoperative complications and simplifies the management of post-operative morbidity with the neobladder.

    Full Text Available Mirza Asif Baig Shri BM Patil Medical College Hospital and Research Centre, Bijapur Liberal District Education (BLDE University, Bijapur, Karnataka, India Background: Persistent Müllerian duct syndrome (PMDS is a rare autosomal recessive inherited disorder. It is a type of internal male pseudo-hermaphroditism in which Müllerian duct derivatives persist in the phenotypically and karyotypically normal male. The exact incidence is unknown, but to date, approximately 400 cases have been reported. PMDS is caused either by insufficient amount of Müllerian inhibiting factor or insensitivity of the target organs to Müllerian inhibiting factor. The case presented in this report discusses mixed gonadal dysgenesis, a condition that refers to individuals who usually have a differentiated gonad on one side and a streak gonad or testis on the other side. Case summary: A 27-year-old male patient presented with cryptorchidism and a left inguinal hernia. On exploratory laparotomy, a uterus with bilateral adnexa was noted, and histopathology revealed the features of mixed gonadal dysgenesis associated with PMDS. The closest differential diagnosis for this condition is true hermaphroditism. Conclusion: PMDS is a rare disorder, and is important to diagnose this condition early because 30% of the cases progress to gonadoblastomas like dysgerminoma, yolk sac tumor, and embryonal carcinoma, and hence gonadectomy is necessary. The very rare nature of this condition and grave prognosis merits its reporting.

    The incidence of hydatidiform moles is 1 per 1,000 pregnancies. Ectopic pregnancy occurs in 20 per 1,000 pregnancies. Thus, the incidence of the ectopic molar gestation is very rare. We report a case of tubal molar pregnancy diagnosed at the systematic histology exam of an ectopic pregnancy. We report the case of 32 years old nulliparus women who presented a vaginal bleeding, lower abdominal pain and 6 weeks amenorrhea corresponding to the last menstrual period. At the clinical examination, the arterial pressure was 100/60 mmHG. The gynecological examination was difficult because of lower abdominal pain. Serum gonadotropin activity was 3454 ui/l. Pelvic ultrasound revealed an irregular echogenic mass in the left adnexa. Diagnostic laparoscopy revealed a left-sided unruptured ampullary ectopic pregnancy. A left laparoscopic salpingectomy was performed. The systematic histologic test identified an ectopic partial molar pregnancy, which was confirmed by DNA ploidy image analysis. The patient was followed with weekly quantitative B-hCG titers until three successive B-hCG levels were negative. It is pertinent that clinicians take routine histological examination of tubal specimens in ectopic pregnancy very seriously in order to diagnose cases of ectopic molar gestations early and mount appropriate post treatment surveillance.

  7. Obstetrical US: What is expected of us

    International Nuclear Information System (INIS)

    Obstetric US in 1987 has become extremely sophisticated, and the American College of Radiology and the AIUM have published guidelines for a standard antepartum obstetric US examination. These guidelines are reviewed and examples of the measurements necessary for gestational dating are given. It is recommended that all US procedures be documented with a written report for medical records and a permanent record of the image. In the first trimester it is important to locate the gestational sac and identify an embryo. The crown-rump length is used for gestational dating, and fetal life is usually detectable after 7 menstrual weeks. The uterus, cervix, and adnexa should also be examined. In the second and third trimesters, US should be used to determine the presence of fetal life, number of concepti, and presentation. The amount of amniotic fluid should be noted. Placental location should be determined and the relationship of the cervix to the tip of the placenta noted. Assessment of gestational age should include at least two of the following: biparietal diameter, head circumference, abdominal circumference, and femur length. A careful evaluation of fetal anatomy should include the following six regions: cerebral ventricles, spine, stomach, urinary bladder, cord insertion site in the abdominal wall, and renal region. Examples of fetal anomalies detected in these six anatomic regions are reviewed

    Full Text Available Torsion of ovary is an infrequent cause of surgical emergency in pregnancy. Most frequently ovarian torsion occurs in first trimester, occasionally in second and rarely in the third trimester. Diagnosis of ovarian torsion is challenging due to non-specific clinical features. We report here a case of dermoid cyst causing ovarian torsion in second trimester and imaging modalities for its diagnosis and management. A case of 19 year old primi at 24 weeks of gestational age came with complaints of pain in right iliac fossa for 2 days. USG done showed non vascular heterogeneous hyper echoic lesion in right adnexa, suggestive of torsion of right ovary with viable intrauterine fetus. She underwent emergency laparotomy, during which we removed necrotic and gangrenous right ovary and fallopian tube. Ovarian torsion is an infrequent cause of abdominal pain in pregnancy. Though it occurs most frequently in first trimester, it may occur in second trimester also. USG is an accurate tool in diagnosing torsion. Early surgical management is associated with favorable maternal and fetal outcome. [Int J Reprod Contracept Obstet Gynecol 2014; 3(4.000: 1134-1137

    2015-08-01

    The head and neck region is a common site for extranodal lymphomas, second only to the gastrointestinal tract; and 12% to 15% of all head and neck tumors are lymphomas. Non-Hodgkin lymphomas are most common, and Hodgkin lymphoma occurs rarely at extranodal sites in the head and neck. Most non-Hodgkin lymphomas of the head and neck region are of B-cell lineage, and the Waldeyer ring is the most common site. Head and neck lymphomas have distinctive epidemiological and clinicopathologic features, including an association with immunosuppression, infectious organisms, or autoimmune disorders; site-specific differences (eg, thyroid gland versus ocular adnexa) for common lymphomas, such as extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue; and genetic differences that provide insights into etiology. Furthermore, the diagnosis of non-Hodgkin lymphomas at extranodal sites implies differences in prognosis and therapeutic implications with lymphomas at nodal sites. In this review, we discuss various types of non-Hodgkin lymphomas and Hodgkin lymphoma, focusing on unique aspects related to the head and neck region. We also discuss a number of newer entities that are clinically indolent as well as mimics of lymphoma that can occur in the head and neck region, including infectious mononucleosis, Kikuchi-Fujimoto disease, Kimura disease, Castleman disease, and immunoglobulin G4-related disease.

    2016-01-01

    Full Text Available Ovarian torsion in the third trimester of pregnancy leading to a midline laparotomy and caesarean section for the delivery of a preterm baby is an uncommon event. As the woman is likely to present with nonspecific symptoms of lower abdominal pain, nausea, and vomiting, ovarian torsion can often be misdiagnosed as appendicitis or preterm labour. Treatment and the opportunity to preserve the tube and ovary may consequently be delayed. We report the case of a multiparous woman who had undergone two previous caesarean sections at term, presenting at 35 weeks of gestation with a presumptive diagnosis of acute appendicitis. Ultrasonography described a cystic lesion 6 × 3 cm in the right adnexa, potentially a degenerating fibroid or a torted right ovary. MRI of the pelvis was unable to provide further clarity. The patient was managed by midline laparotomy and simultaneous detorsion of the ovarian pedicle and ovarian cystectomy together with caesarean section of a preterm infant. This report describes that prompt recognition and ensuring intraoperative access can achieve a successful maternal and fetal outcome in this rare and difficult scenario. Furthermore, we would like to emphasise that the risk for a pregnant woman and her newborn could be reduced by earlier diagnosis and management of ovarian masses (Krishnan et al., 2011.

  11. MR staging of endometrial carcinoma

    International Nuclear Information System (INIS)

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

    Besnoitia caprae is a tissue cyst-forming protozoan that infects goats and has considerable economic importance in certain regions of Asia and Africa. Murine macrophage J774 cell line was inoculated with tachyzoites of Besnoitia caprae (BC-Pars isolate) collected from mice. A significant growth of tachyzoites was observed in J774. Mice were inoculated with tachyzoites harvested from J774 cell culture. Skin samples from the mice infected with tachyzoites of BC-Pars were PCR positive. One mouse showed alopecia and skin lesions on 45 DPI. Dermal lesions started from around right eye and gradually developed more and more. After euthanasia on 60 DPI, histopathological evaluation of skins around the eye showed necrosis of the epidermis and follicular adnexa with chronic inflammatory cell infiltration. Histopathological sections of their skin showed the presence of necrosis and mononuclear cell infiltration. To the authors' knowledge, this is the first report of successful production of Besnoitia caprae tachyzoites was achieved in vitro by suspension culture technique. Another interesting finding is the report of the alopecia and skin lesions around the eye in mouse that quite similar to lesions of goats due to infection of Besnoitia caprae. PMID:26688623

  13. Other Gynecologic Cancers: endometrial, ovarian, vulvar and vaginal cancers.

    2004-08-25

    HEALTH ISSUE: In Canada, cancers of the endometrium, ovaries, vulva, vagina, placenta and adnexa account for 11% of all malignant neoplasms in women and 81% of all genital cancers. Although the incidence and mortality from vulvar and vaginal cancers are very low, endometrium and ovarian cancer are important public health problems. KEY FINDINGS: In Canada, there has been no appreciable improvement in survival for women with advanced endometrial (EC) or ovarian cancer (OC) over the past 30 years. The prognosis of EC is good for most patients because diagnosis is made at early stages. However, survival of OC is poor; more than 70% of cases are diagnosed at late stages. Up to 10% of OCs is linked to familial aggregation. Cancers of the vulva and of the vagina are very rare. The survival experience for women with the latter is worse than for those with the former. Both share many risk factors with cervical cancer and the recent developments in the study of HPV infection should be applicable to these diseases as well. Of particular interest will be the advent of vaccines for the primary prevention of HPV infection. DATA GAPS AND RECOMMENDATIONS: At present, the best available means to diagnose gynecologic malignancies is a detailed clinical examination, considering the totality of information on potential and proven risk factors, such as age, reproductive health, sexual practices, use unopposed estrogens or of oral contraceptives or tubal ligation, obesity, diet, smoking, and the familial clustering of some of these cancers.

  14. Value of dynamic contrast-enhanced MRI for tissue characterization of ovarian teratomas: Correlation with histopathology

    International Nuclear Information System (INIS)

    Aim: To analyse the value of double contrast-enhanced (DCE) magnetic resonance imaging (MRI) in addition to conventional MRI to characterize ovarian teratomas subtypes with histological correlation. Materials and methods: From January 2005 to December 2008, 38 women undergoing MRI and subsequent resection of ovarian teratomas were identified [40 mature cystic teratomas (MCT), two struma ovarii, three immature teratomas]. MRI images were analysed blindly by two radiologists according to morphological and vascular abnormalities. An experienced histopathologist reviewed all slides to determine the presence and histological composition of Rokitansky protuberances. Results: Thirty-one MCT (77%) had at least one small, regular Rokitansky protuberance presenting at an acute angle with the cyst wall. Ten out of 31 MCT did not display any enhancement on contrast-enhanced MRI related to sebaceous glands, adipose lobules, keratin, and pilosebaceous adnexa at histology. Three different time–intensity curve (TIC), types 1, 2, and 3, were related to presence of smooth muscular cells and fibrous, neuroglial, or thyroid tissue, respectively, found at histology of MCT. Type 3 TIC was also present in one struma ovarii and two immature teratomas. Conclusion: TIC types are related to the specific content of the solid tissue of ovarian teratomas but cannot be used to differentiate benign and malignant ovarian teratomas

    Full Text Available Rupture uterus in first and second trimester in a non-scarred uterus is generally seen with associated mullerian anomalies. A 22 year old primigravida with 16 weeks gestational age presented with pain in abdomen since 6 hours prior to admission and hypovolemic shock. Though she had taken regular antenatal visits and a transabdominal scan at 14-16wks with the report opining a normal study, the diagnosis of the fetus in the rudimentary horn was missed. A provisional diagnosis of rupture of right rudimentary horn of a bicornuate uterus was made afet clinical examination and the TVS showing the cervix continuing into a normal uterus with no fetus within it and a vague right adnexal mass. Transabdominal scan also showed vague hypoechoic mass in the right adnexa with a fetus of 16-17 weeks above the mass with absent cardiac activity. Emergency laparotomy with resuscitation and excision of the ruptured horn and blood transfusion saved the life of the patient. [Int J Reprod Contracept Obstet Gynecol 2014; 3(1.000: 248-250

    Full Text Available A unicornuate uterus with a rudimentary horn is a rare mullerian abnormality which may cause many gynaecological and obstetrical complications like infertility, endometriosis, hematometra, abortions, and preterm deliveries; and is usually associated with urinary tract anomalies. Pregnancy in a non-communicating rudimentary horn is very difficult to diagnose before it ruptures, leading to life -threatening intraperitoneal hemorrhage, which usually presents in the second or third trimester. A 23 year old G2P1L1 in lactational amenorrhea was admitted to the labour room with haemorrhagic shock. Provisionally diagnosed as ruptured ectopic pregnancy, patient was taken for laparotomy after resuscitation. Intraoperative findings were: haemoperitoneum of 3 liters, unicornuate uterus with a ruptured left rudimentary non-communicating horn containing products of conception, and macroscopically normal fallopian tubes and ovaries. The left adnexa were attached to the rudimentary horn. Excision of the rudimentary horn was done. The fetus, weighing about 250 grams, was recovered en-sac from the peritoneal cavity. There is a need for an increased awareness of rudimentary horn pregnancy especially in developing countries where the possibility of detection before pregnancy or before the rupture is unlikely, and precious time is lost in shifting these women to the referral hospital.

    Sijmons, Rolf H; Hofstra, Robert M W

    2016-02-01

    Inherited mutations of the DNA Mismatch repair genes MLH1, MSH2, MSH6 and PMS2 can result in two hereditary tumor syndromes: the adult-onset autosomal dominant Lynch syndrome, previously referred to as Hereditary Non-Polyposis Colorectal Cancer (HNPCC) and the childhood-onset autosomal recessive Constitutional Mismatch Repair Deficiency syndrome. Both conditions are important to recognize clinically as their identification has direct consequences for clinical management and allows targeted preventive actions in mutation carriers. Lynch syndrome is one of the more common adult-onset hereditary tumor syndromes, with thousands of patients reported to date. Its tumor spectrum is well established and includes colorectal cancer, endometrial cancer and a range of other cancer types. However, surveillance for cancers other than colorectal cancer is still of uncertain value. Prophylactic surgery, especially for the uterus and its adnexa is an option in female mutation carriers. Chemoprevention of colorectal cancer with aspirin is actively being investigated in this syndrome and shows promising results. In contrast, the Constitutional Mismatch Repair Deficiency syndrome is rare, features a wide spectrum of childhood onset cancers, many of which are brain tumors with high mortality rates. Future studies are very much needed to improve the care for patients with this severe disorder. PMID:26746812

    Full Text Available Background: Tubal sterilization is the permanent and effective contraception method. This can be performed at any time, but at least half are performed in conjunction with cesarean or vaginal delivery and are termed puerperal. The most complication after tubal ligation is ectopic pregnancy. Ectopic pregnancy is the leading cause of maternal death in first trimester.Case presentation: We present a 33 years old woman gravida5, para4, all normal vaginal delivery, presented with complaints of delayed menstrual period, pelvic pain and spotting. She underwent tubal ligation for two times. For the first time she had puerperal Pomeroy tubal sterilization after third child delivery. Intra uterine pregnancy occurred three years later. One day after vaginal delivery of fourth child, she underwent post partum tubal ligation with the Parkland method. Tubal pregnancy occurred nine months later. Physical examination identified acute abdomen. Pelvic ultrasound showed no gestational sac in uterine cavity. The sac with fetal pole was in right adnexa. Beta-HCG was 2840mIU/ml. She underwent laparotomy. Surgical management included salpingectomy with cornual resection in both sides. The surgery identified Ectopic pregnancy.Conclusion: Any symptoms of pregnancy in a woman after tubal ligation must be investigated; an ectopic pregnancy should be excluded. Ectopic pregnancy must be considered, in any woman with lower abdominal pain, missed period and vaginal bleed-ing. Conception after tubal sterilization can be explained by fistula formation and re-canalization of fallopian tube.

  19. Contrast-enhanced ultrasound and computed tomography findings of recurrent ovarian steroid cell tumor presenting with peritoneal seeding: A case report

    International Nuclear Information System (INIS)

    We present ultrasonography and computed tomography (CT) findings of a case of recurrent ovarian steroid cell tumor presenting with peritoneal seeding in a 45-year-old woman. On abdominal ultrasonography, there were multiple hypoechoic round masses in the peritoneal cavity including the perihepatic area. Contrast-enhanced ultrasonography showed intense homogenous enhancement on the arterial phase and delayed prolonged enhancement of the masses. CT revealed multiple peritoneal solid masses with strong enhancement. Five years ago, the patient had been diagnosed with a steroid cell tumor of the left ovary. At that time, the CT showed a well-enhancing, lobulating, large solid mass at the left adnexa. Imaging findings of the peritoneal masses suggested peritoneal seeding from the preexisting ovarian steroid cell tumor. For treatment of the metastatic lesions in the perihepatic area, ultrasonography-guided radiofrequency ablation (RFA) was performed, and debulking surgery for the peritoneal masses was done. Six months later, complete ablation of the perihepatic metastases by RFA and a marked decrease in the peritoneal metastases by surgery were found on the follow-up CT.

  20. A probable radiation-induced epidermal carcinoma in a sheep

    International Nuclear Information System (INIS)

    The sheep discussed in this report was one of 12 wether lambs given daily doses of 144Ce-144Pr to investigate the effect of radionuclides on the alimentary tract. The sheep received 20 mCi daily over a 16 day period when treatment was discontinued due to the development of sever diarrhea and later anorexia. Changes in the sheep reported (alopecia, ulceration, disappearance of adnexa, and fibrous replacement of the dermal collagen) indicate a radiation dose in excess of that used in previous experiments. About 4.5 yr after dosing, a firm enlargement was noticed in the right ventrolateral coccygeal region. As the enlargement increased in size, ulceration and bacterial infection occurred. The sheep was killed 59 months after initial treatment and a necropsy performed. The findings were consistent with the diagnosis of locally invasive squamouscell carcinoma. The authors feel that the relative rarity of epidermal carcinomas in sheep, exposure of the coccygeal area to large doses of irradiation, and the carcinogenic effect of radiation indicates a probable cause-and-effect relationship of radiation and tumour development.

    Full Text Available Ocular complications are known to occur as a result of human immunodeficiency virus (HIV disease. They can be severe leading to ocular morbidity and visual handicap. Cytomegalovirus (CMV retinitis is the commonest ocular opportunistic infection seen in acquired immune deficiency syndrome (AIDS. Though posterior segment lesions can be more vision-threatening, there are varied anterior segment manifestations which can also lead to ocular morbidity and more so can affect the quality of life of a HIV-positive person. Effective antiretroviral therapy and improved prophylaxis and treatment of opportunistic infections have led to an increase in the survival of an individual afflicted with AIDS. This in turn has led to an increase in the prevalence of anterior segment and adnexal disorders. Common lesions include relatively benign conditions such as blepharitis and dry eye, to infections such as herpes zoster ophthalmicus and molluscum contagiosum and malignancies such as squamous cell carcinoma and Kaposi′s sarcoma. With the advent of highly active antiretroviral therapy, a new phenomenon known as immune recovery uveitis which presents with increased inflammation, has been noted to be on the rise. Several drugs used in the management of AIDS such as nevirapine or indinavir can themselves lead to severe inflammation in the anterior segment and adnexa of the eye. This article is a comprehensive update of the important anterior segment and adnexal manifestations in HIV-positive patients with special reference to their prevalence in the Indian population.

    To determine the radiologic features of primary malignant tumors of the fallopian tube. By observing six computed tomograms and one MR image, we determined the radiologic features of seven pathologically proven primary malignant tumors of the fallopian tube. The location, size, internal appearances (cystic/mixed/solid) of the tumor were analysed, and the presence or absence of ipsilateral ovary, hydrosalpinx, intrauterine fluid collection, pelvic ascites and lymphadenopathy were determined. All seven tumors were located in unilateral adnexa. Their mean diameter was 3.5 (range, 1.5-6) cm, and their morphological appearance was solid in five cases and mixed in two. In no case were ipsilateral ovaries identified. Hydrosalpinx was noted in four cases (57%) and intrauterine fluid collection in five (71%). Pelvic ascites and lymphadenopathy were each observed in one case (14%). Although it is difficult to differentiate between primary malignant tumors of the fallopian tube and other adnexal tumors, a pelvic mass with hydrosalpinx and intrauterine fluid collection suggests a primary malignant tumor of the fallopian tube.

    Abdominal pregnancy is a very rare form of ectopic pregnancy, associated with high morbidity and mortality for both fetus and mother. It is, and often, seen in poor resource nations, where early diagnosis is often a major challenge due to poor prenatal care and lack of medical resources. An advanced abdominal pregnancy with a good fetal and maternal outcome is therefore a more extraordinary occurrence in the modern developed world. We present a case of an abdominal pregnancy at 33.4 weeks in an individual with no documented prenatal care, who arrived in a hospital in the Bronx, in June 25th 2014, with symptoms of generalized, severe lower abdominal pain. Upon examination it was found that due to category III fetal tracing an emergent cesarean section was performed. At the time of laparotomy the fetus was located in the pelvis covered by the uterine serosa, with distortion of the entire right adnexa and invasion to the right parametrium. The placenta invaded the pouch of Douglas and the lower part of the sigmoid colon. A massive hemorrhage followed, followed by a supracervical hysterectomy. A viable infant was delivered and mother discharged on postoperative day 4. PMID:25544940

    Full Text Available Pilomatricoma (PMC is a relatively uncommon benign skin neoplasm arising from the skin adnexa. Since the first description of PMC in 1880, there has been a gradual increase in understanding of the morphologic features and clinical presentation of this tumor. However, difficulties still persist in making clinical and cytologic diagnosis. We report the clinical and histopathological findings of two cases of pilomatricoma. In case 1, a 10-year-old girl presented with a right upper back mass. In case 2, a nine-year-old girl presented with a left ear lobe mass. The clinical findings in both the cases were suggestive of epidermoid/dermoid cyst. However, subsequent histopathologic examination confirmed these cases as pilomatricoma. This report reveals that pilomatricoma is a frequently misdiagnosed entity in clinical practice. The purpose of this article is to create awareness among clinicians on the possibility of pilomatricoma as a cause of solitary skin nodules, especially those on the head, neck or upper extremities.

  6. Distinct spatiotemporal expression of serine proteases Prss23 and Prss35 in periimplantation mouse uterus and dispensable function of Prss35 in fertility.

    Directory of Open Access Journals (Sweden)

    Honglu Diao

    Full Text Available PRSS23 and PRSS35 are homologous proteases originally identified in mouse ovaries. In the periimplantation mouse uterus, Prss23 was highly expressed in the preimplantation gestation day 3.5 (D3.5 uterine luminal epithelium (LE. It disappeared from the postimplantation LE and reappeared in the stromal compartment next to the myometrium on D6.5. It was undetectable in the embryo from D4.5 to D6.5 but highly expressed in the embryo on D7.5. Prss35 became detectable in the uterine stromal compartment surrounding the embryo on D4.5 and shifted towards the mesometrial side of the stromal compartment next to the embryo from D5.5 to D7.5. In the ovariectomized uterus, Prss23 was moderately and Prss35 was dramatically downregulated by progesterone and 17β-estradiol. Based on the expression of Prss35 in granulosa cells and corpus luteum of the ovary and the early pregnant uterus, we hypothesized that PRSS35 might play a role in female reproduction, especially in oocyte development, ovulation, implantation, and decidualization. This hypothesis was tested in Prss35((-/- mice, which proved otherwise. Between wild type (WT and Prss35((-/- mice, superovulation of immature females produced comparable numbers of cumulus-oocyte complexes; there were comparable numbers of implantation sites detected on D4.5 and D7.5; there were no obvious differences in the expression of implantation and decidualization marker genes in D4.5 or D7.5 uteri. Comparable mRNA expression levels of a few known protease-related genes in the WT and Prss35((-/- D4.5 uteri indicated no compensatory upregulation. Comparable litter sizes from WT × WT and Prss35((-/-× Prss35((-/- crosses suggested that Prss35 gene was unessential for fertility and embryo development. Prss35 gene has been linked to cleft lip/palate in humans. However, no obvious such defects were observed in Prss35((-/- mice. This study demonstrates the distinct expression of Prss23 and Prss35 in the periimplantation uterus

    The use of a combined therapy with low doses of estrogens plus antidepressants to treat depression associated to perimenopause could be advantageous. However the use of these combinations is controversial due to several factors, including the time of intervention in relation to menopause onset. This paper analyzes whether time post-OVX influences the antidepressant-like action of a combination of ethynyl-estradiol (EE2) and citalopram (CIT) in the forced swim test (FST). Middle-aged (15 months old) female Wistar rats were ovariectomized and after one or three weeks treated with EE2 (1.25, 2.5 or 5.0 µg/rat, s.c.; −48 h) or CIT (1.25, 2.5, 5.0 or 10 mg/kg, i.p./3 injections in 24 h) and tested in the FST. In a second experiment, after one or three weeks of OVX, rats received a combination of an ineffective dose of EE2 (1.25 µg/rat, s.c., −48 h) plus CIT (2.5 mg/kg, i.p./3 injections in 24 h) and subjected to the FST. Finally, the uteri were removed and weighted to obtain an index of the peripheral effects of EE2 administration. EE2 (2.5 or 5.0 µg/rat) reduced immobility after one but not three weeks of OVX. In contrast, no CIT dose reduced immobility at one or three weeks after OVX. When EE2 (1.25 µg/rat) was combined with CIT (2.5 mg/kg) an antidepressant-like effect was observed at one but not three weeks post-OVX. The weight of the uteri augmented when EE2 was administrated three weeks after OVX. The data suggest that the time post-OVX is a crucial factor that contributes to observe the antidepressant-like effect of EE2 alone or in combination with CIT. PMID:27153072

    Full Text Available Abstract Background Preterm birth is the leading cause of all infant mortality. In 2004, 12.5% of all births were preterm. In order to understand preterm labor, we must first understand normal labor. Since many of the myometrial changes that occur during pregnancy are similar in mice and humans and mouse gestation is short, we have studied the uterine genes that change in the mouse during pregnancy. Here, we used microarray analysis to identify uterine genes in the gravid mouse that are differentially regulated in the cyclooxygenase-1 knockout mouse model of delayed parturition. Methods Gestational d18.0 uteri (n = 4 were collected from pregnant wild-type and cyclooxygenase-1 knockout mice. Part of the uterus was used for frozen sections and RNA was isolated from the remainder. Microarray analysis was performed at the Indiana University School of Medicine Genomic Core and analyzed using the Microarray Data Portal. Northern analysis was performed to confirm microarray data and the genes localized in the gravid uterus by in situ hybridization. Results We identified 277 genes that are abnormally expressed in the gravid d18.0 cyclooxygenase-1 knockout mouse. Nine of these genes are also regulated in the normal murine uterus during the last half of gestation. Many of these genes are involved in the immune response, consistent with an important role of the immune system in parturition. Expression of 4 of these genes; arginase I, IgJ, Tnfrsf9 and troponin; was confirmed by Northern analysis to be mis-regulated during pregnancy in the knockout mouse. In situ hybridization of these genes demonstrated a similar location in the gravid wild-type and Cox-1 knockout mouse uteri. Conclusion To our knowledge, this is the first work to demonstrate the uterine location of these 4 genes in the mouse during late pregnancy. There are several putative transcription factor binding sites that are shared by many of the 9 genes identified here including; estrogen and

    Full Text Available Lediglich Fachärzte für Gynäkologie und Geburtshilfe dürfen laut österreichischem Fortpflanzungsmedizingesetz intrauterine Inseminationen durchführen. Nach Vorlage eines Notariatsakts ist es auch unverheirateten Paaren gestattet, diesen Eingriff vornehmen zu lassen. In Österreich ist die Durchführung einer heterologen Insemination (Samen von Dritten in dafür zugelassenen Krankenanstalten erlaubt. Die häufigste Indikation für eine IUI ist die idiopathische Infertilität, aber auch bei Ejakulationsproblemen und bei Pathologien an der Portio und der Cervix uteri sowie bei immunologischen Erkrankungen findet die IUI ihre Anwendung. Grundsätzlich ist bei Frauen mit einem regelmäßigen Zyklus eine hormonelle Stimulation nicht vonnöten. Zu beachten ist, dass eine hormonelle Stimulation zwar zur Steigerung der Erfolgschancen führt, jedoch häufig auch mit Komplikationen, wie beispielsweise Mehrlingsschwangerschaften oder einer Überstimulation, verbunden ist. Wichtig bei der Samenaufbereitung für eine IUI ist die Trennung der Spermien von Seminalflüssigkeit, Bakterien, Leukozyten und Zelldebris sowie die Gewinnung von 2–5 Millionen gut beweglichen Spermien. Es gibt unterschiedliche Aufbereitungsmethoden wie die Swim-up-Technik oder die Dichte-Gradienten-Zentrifugation, welche jedoch für die Aufreinigung der Spermien Zentrifugationsschritte benötigen, was eine mechanische Belastung für die Spermien darstellt. Eine neue, sehr einfache, schonende und kostengünstige Methode bietet der Zech-Selector®, welcher als einzige Methode in der Lage ist, auf einfache Weise nahezu alle Spermien mit DNAStrangbrüchen zu eliminieren. Ein weiterer wichtiger Bestandteil für eine erfolgreiche IUI ist die Wahl des Katheters. Dieser muss für die IUI zugelassen sein und darf beim Einführen keine Schleimhautverletzungen herbeiführen. Des Weiteren sollten nicht mehr als 0,5 ml Flüssigkeit in das Cavum uteri eingespritzt werden. Optimal ist es, die

    Full Text Available Abstract Background The possibility for isolating bovine mesenchymal multipotent cells (MSCs from fetal adnexa is an interesting prospect because of the potential for these cells to be used for biotechnological applications. Bone marrow and adipose tissue are the most common sources of MSCs derived from adult animals. However, little knowledge exists about the characteristics of these progenitors cells in the bovine species. Traditionally most cell cultures are developed in two dimensional (2D environments. In mammalian tissue, cells connect not only to each other, but also support structures called the extracellular matrix (ECM. The three-dimensional (3D cultures may play a potential role in cell biotechnology, especially in tissue therapy. In this study, bovine-derived umbilical cord Wharton’s jelly (UC-WJ cells were isolated, characterized and maintained under 3D-free serum condition as an alternative of stem cell source for future cell banking. Results Bovine-derived UC-WJ cells, collected individually from 5 different umbilical cords sources, were successfully cultured under serum-free conditions and were capable to support 60 consecutive passages using commercial Stemline® mesenchymal stem cells expansion medium. Moreover, the UC-WJ cells were differentiated into osteocytes, chondrocytes, adipocytes and neural-like cells and cultured separately. Additionally, the genes that are considered important embryonic, POU5F1 and ITSN1, and mesenchymal cell markers, CD105+, CD29+, CD73+ and CD90+ in MSCs were also expressed in five bovine-derived UC-WJ cultures. Morphology of proliferating cells typically appeared fibroblast-like spindle shape presenting the same viability and number. These characteristics were not affected during passages. There were 60 chromosomes at the metaphase, with acrocentric morphology and intense telomerase activity. Moreover, the proliferative capacity of T cells in response to a mitogen stimulus was suppressed when

  12. Is there a role for radiation therapists within veterinary oncology?

    International Nuclear Information System (INIS)

    Role expansion recognises enlargement of existing scope of practice within radiation therapy (RT). Over the past decade, there has been increasing involvement and movement towards advanced practice in the form of role extension in specialised areas of practice including brachytherapy, image fusion and quality assurance. It is also recognised that radiation therapy expert practitioners exist in the areas of imaging immobilisation, treatment, education and research. The acquisition of additional skills has hastened the need for autonomy within the RT profession and with this comes the responsibility to share our knowledge and specialist abilities with the wider community. Radiation therapy is a highly specialised profession working to treat a commonly encountered ailment like cancer and we should ask ourselves what other community members could benefit from our knowledge and skills. Cancer is not limited to the human population but affects animals as readily and severely. Particular types of cancers have been identified as being comparable with that of humans; one such tumour is squamous cell carcinoma (SCC). Squamous cell carcinoma is the most commonly found tumour of the eye and adnexa in horses. Comparatively, SCC in humans is the most common cancer in Australia. Whilst human treatment is well established with surgery and radiation therapy offering comparable control rates, the treatment within Australia's Veterinary Oncology field is currently at a standstill. It is reported, however, that the use of interstitial brachytherapy has been shown to be highly effective and thoroughly practiced and established within the United States of America (USA). This paper reviews current literature in readiness for the potential for radiation therapy cross-over into the veterinary sphere with regard to the implementation of treatment and radiation safety protocols for the use of interstitial brachytherapy in horses.

  13. Life span study report 10 - 1

    International Nuclear Information System (INIS)

    The present study extends the previous report on cancer mortality among atomic bomb survivors by adding data from four additional years of follow-up (1979 - 82) and by expanding the cohort (now designated LSS-E85) to include 11,393 Nagasaki survivors located between 2,500 - 9,999 m from the hypocenter at the time of the bombing (ATB). Significant dose responses were observed for leukemia, for cancers of the lung, female breast, stomach, colon, esophagus, and urinary bladder, and for multiple myeloma. Four new categories of cancer were also investigated: the results for cancers of the liver and intrahepatic bile ducts and of the ovary and other uterine adnexa were suggestive of significant radiation effects, but the positive dose responses for cancers of the gallbladder and prostate were not significant. Due to diagnostic difficulties and the lack of evidence for radiogenic effects at these sites, the results for liver and ovarian cancers do not provide convincing evidence for radiogenic effects. With the exception of multiple myeloma, the relative risk (RR) of radiation-induced cancer mortality was greater for women than for men, for each nonleukemic cancer with a significant overall dose response. These differences can be attributed in large measure to differences in the background cancer mortality rates, which are generally much higher for men than women. For leukemia there was no significant sex difference in the RR, while for multiple myeloma women had a slightly, though nonsignificantly, lower RR than males. A statistically significant interaction (p = .008) between the effects of age ATB and attained age on radiation-related mortality was also observed for cancers other than leukemia. In particular, the initially large RRs seen in those who were young ATB have decreased with time, while the smaller RRs for those who were older ATB tended to increase. (author)

    The objective of this study was to evaluate the role of the fimbriated end and nonfimbriated epithelium of fallopian tubes with regard to p53 signature, tubal intraepithelial lesions in transition (TILT), and serous tubal in-situ carcinoma (STIC) in cases of different kinds of serous pelvic cancer. This study immunohistochemically evaluated (by Ki-67 and p53 staining) the presence of p53 signature, TILT lesions, and STIC in 14 consecutive cases of prophylactic salpingo-oophorectomy in women with BRCA-1/2 mutation (bilateral salpingo-oophorectomy), 11 cases of macroscopically inconspicuous adnexae of patients with primary contralateral tubal cancer (TC), 9 cases of primary peritoneal cancer (PPC), and 10 cases of serous ovarian borderline tumors, evaluating the fallopian tubes (using the Sectioning and Extensively Examining the FIMbria protocol), ovarian surface epithelium, and ovarian cortical inclusion cysts. The frequencies of p53 signature, TILT, and STIC were 35.7%, 7.1%, and 0% in cases of prophylactic surgery, 18.2%, 9.1%, and 18.2% in TC, and 11.1%, 0%, and 33.3% in PPC. These precursor lesions were missed during the initial routine screening and were found in the fimbriated end of the fallopian tubes in 94%. In 1 case of PPC, staining for p53 was negative in STIC. The studied adnexal tissue of serous ovarian borderline tumor and ovarian cortical inclusion cysts of all cases showed no alterations according to p53 signature, TILT, or STIC. STIC and p53 signature as precursor lesions of pelvic serous cancer were seen in macroscopically inconspicuous contralateral fallopian tubes in unilateral TC, in patients with elective bilateral salpingo-oophorectomy, and in patients affected by PPC. Therefore, we propose the complete processing of adnexal tissue and the use of step sectioning to establish the correct diagnosis. Immunohistochemistry for p53 and ki-67 may aid in the diagnosis, but is not necessary for routine investigation. PMID:21804388

    We present a patient with persistent bilateral megalocystic ovaries following in vitro fertilization which was detected during cesarean section. A 24 year-old primigravida presented to our clinic at the 36(th) week of a twin pregnancy with labour pain and cervical dilatation. On ultrasound examination, 2 masses of 90×60 and 60×70 mm were seen in the right and left adnexal regions respectively. Her history showed that she had unexplained infertility for 4 years and had undergone IVF with gonadotropin releasing hormone (GnRH)-agonist stimulation. Two embryos were transferred. Twin pregnancy was detected on ultrasound examination. The patient was delivered by emergency caesarean section due to transverse presentations at 36(th) weeks of gestation. During the operation, both adnexae were markedly enlarged, the right ovary measuring about 15×18 cm and the left about 16×18 cm. There was minimal ascites in the abdominal cavity. Ovarian biopsy was performed and the final pathology report showed bilateral follicle cysts. The patient was discharged on the postoperative 4(th) day. The patient was seen 4 weeks later. She had no complaints and ultrasound follow-up revealed a normal size uterus and ovaries. We should keep in mind that hyperstimulated, enlarged ovaries and its complication may be seen in the late weeks of pregnancy, even at term, in cases of in vitro fertilization cases. Therefore, close follow-up of pregnant IVF patints is recommended whether they had OHSS or not, because ovarian torsion caused by hyperstimulated ovaries may be difficult to diagnose during pregnancy.

    To evaluate the phenotype of macrophages in the cornea and conjunctiva of C57BL/6 mice with induced experimental dry eye. C57BL/6 mice exposed to desiccating stress (DS) were evaluated at 1, 5, and 10 days and C57BL/6 mice maintained in non-stressed environment were used as controls. Whole eyes and adnexa were excised for histology or used for gene expression analysis. Location and phenotype of macrophages infiltrating the cornea and conjunctiva was evaluated by immunofluorescence analysis. Quantitative polymerase chain reaction evaluated macrophage markers and T cell-related and inflammatory cytokine expression in cornea and conjunctiva. Immunofluorescence staining demonstrated that macrophages reside in the conjunctiva of control and dry eye mice and their number did not change with DS. Real-time RT-PCR demonstrated that the level of M1 macrophage marker, iNOS, increased prominently in the conjunctiva at DS 10 days. In contrast, there was a non-significant decrease of the M2 marker Arg1 with DS. The levels of inflammatory cytokine, IL-12a mRNA transcript in the conjunctiva increased significantly at DS1 and decreased at DS5, while levels of IL-18 were significantly increased at DS 10. Macrophages reside in the ocular surface tissues of C57BL/6 mice. Although the number of macrophages in the conjunctiva does not change, evidence of inflammatory M1 activation after desiccating stress was observed. Better understanding of phagocyte diversity and activation in dry eye disease provide a basis for the development of phagocyte-targeted therapeutic strategies. PMID:25772203

    Full Text Available Objective: Epithelioid hemangioendothelioma is a rare member of vascular tumors of intermediate malignancy. Recently, presence of t(1;3 translocation and WWTR1/CAMTA1 gene fusion, which enhances CAMTA1 expression, are found to be specific to this tumor. We investigated the CAMTA1 immune expression profile of epithelioid hemangioendothelioma and its potential mimickers using a commercially available CAMTA1 antibody. Material and Method: Standard whole sections from the formalin fixed, paraffin embedded blocks of 12 epithelioid hemangioendotheliomas, 10 angiosarcomas, 9 epithelioid sarcomas, 8 malignant melanomas, 8 signet ring carcinomas, 7 lobular carcinomas of breast, 2 epithelioid mesotheliomas, 2 rhabdoid tumors and 12 miscellaneous hemangiomas were immunostained for anti-CAMTA1 (ab64119, 1:200; Abcam after pretreatment with citrate pH 6.0 for 20 minutes using Leica Bond detection kit with DAB chromogen. Strong nuclear CAMTA1 expression was scored for its extent as ‘negative’ (50% positive. Results: In 60 out of 70 cases (86% either 2+ or 3+ strong nuclear staining was seen. Eighty-three % of epithelioid hemangioendotheliomas, 100% of angiosarcomas, 89% of epithelioid sarcomas, 89% of malignant melanomas, 63% of signet ring carcinomas, 71% of lobular carcinomas of breast, 100% of epithelioid mesotheliomas, 50% of rhabdoid tumors and 100% of hemangiomas were stained. Besides neurons, CAMTA1 expression was also observed in squamous epithelium, skin adnexa, breast lobules, prostate glands, bile ducts, colonic mucosa and gastric pits. Conclusion: Epithelioid hemangioendothelioma, its potential morphological mimickers and other benign or malignant vascular tumors showed strong and diffuse CAMTA1 expression, nullifying the potential use of CAMTA1 immunohistochemistry as an adjunct in the differential diagnosis.

    Full Text Available BACKGROUND: Eye diseases are important cause of medical consultation in children, with the spectrum varying in different localities. This study aimed to determine the spectrum of childhood eye diseases in a tertiary hospital serving rural and semi-rural communities. METHODS: We conducted a retrospective review of all patients less than 15 years old who presented to the eye clinic of Wesley Guild Hospital Ilesa, Nigeria between January 2001 and December 2006. Data on age at presentation, age at onset of disease, sex and diagnosis were collected and analyzed using SPSS. A p value less than 0.05 was considered statistically significant. RESULTS: We evaluated the reports of 286 children, with a male:female ratio of 1:1.1. Children aged 11-15 years made up the largest group (p=0.013. Ocular trauma (21.7%, allergic conjunctivitis (17.8%, infections of the eye and its adnexa (15.4% and refractive errors (14.3% were the most common conditions. Ocular injury was more common in males (p=0.002 and children aged 6-10 years, and 87.1% of these cases were a closed globe injury. Infections were seen more commonly among females and children aged 0-5 years, with keratitis representing 40.9% of these cases. Congenital eye disease represented 13.3% of childhood eye diseases. CONCLUSION: The prevalent childhood eye diseases recorded here can lead to absenteeism from school and are potentially blinding. Health education aimed at the prevention of ocular trauma and prompt presentation for the management of other eye diseases should be encouraged.

    Pelvic carcinosarcomas (PCSs) are rare aggressive biphasic tumors that localize in the ovary, fallopian tube, or peritoneum and present frequently as bilateral disease. We undertook a morphological, p53 immunohistochemical and TP53 gene mutational analysis study in a single institution cohort of 16 PCSs in order to investigate the nature of bilateral tumors and to shed light on their origin and pathogenesis. Of the 16 patients, 10 presented with bilateral disease, 6 with a carcinosarcoma in both adnexa, and the remaining cases with a carcinosarcoma in one adnexum and a carcinoma in the opposite. The carcinoma component showed high-grade serous features in 13/16 of cases (81 %). In 10 patients (63 %), a serous tubal intraepithelial carcinoma (STIC) was found, in one case bilateral, making a total of 11 STICs. STIC was found only in cases with a carcinoma component with high-grade serous features. All 10 bilateral tumors and all 11 PCS-associated STICs showed a similar p53 immunostaining pattern. At mutation analysis of the TP53 gene, all five bilateral PCS contained an identical mutation in both localizations. Furthermore, a TP53 mutation was found in 8 of 10 STICs, with an identical mutation in the associated PCS. The finding of similar p53 immunostaining in all bilateral cases and identical TP53 mutations in most PCS-associated STIC provides evidence for a clonal relation between these neoplastic lesions, supporting a metastatic nature of bilateral PCS and suggesting that they have an extraovarian origin in a STIC.

    Given exogenously, ALA defeats intrinsic regulatory feedback mechanisms allowing intracellular accumulation of protoporphyrin IX (PpIX), a highly efficient photosensitizer. In vivo, PpIX synthesis in neoplastic mammary tissues averages 20-fold higher than in normal mammary tissues. PpIX is retained intracellularly, unlike perivascular localization of other photosensitizers, and it is then cleared quickly from the body. In vitro, ALA induced PpIX production in our laboratory in 6 cell lines tested, including an established feline kidney cell line and dermal fibroblasts from primary skin biopsy explant, resulting in photosensitization. Fluorescent microscopy confirmed PpIX production in skin adnexae following ALA administration in a normal cat. To evaluate toxicity, three cats were treated with a single i.v. dose of ALA (either 100, 200, of 400 mg/kg) and followed for 7 days. Cats receiving 100 or 200 mg/kg ALA i.v. had elevated liver enzymes and bilirubin within 24 hours. Histopathology revealed hydropic changes in the liver and renal fibrosis. The cat receiving 400 mg/kg ALA intravenously had cutaneous flush, bradycardia and apnea associated with ALA administration; within 24 hours the cat was lethargic, anorectic and icteric. ALT, AST and bilirubin concentrations had increased significantly. At necropsy the liver had a prominent lobular pattern; histopathology revealed severe periportal hepatitis and splenic necrosis. Systemically administered ALA induces PpIX production, but toxicity may preclude its clinical application in the cat. PpIX levels seem to be more time dependent than those dependent at these three ALA doses and they are well beyond the saturation point for adequate PpIX conversion. The literature is scant regarding toxicity associated with parenteral administration of ALA.

Certain patterns have been revealed at the distribution by ages of 21-30 years, 12 people (26%), from 31-40 years old, 7 patients (15,2%), from 41 to 50 years, 18 men (39,1%), from 51-60 years, 8 persons (17,4%), more than 60 years, 1 person (2,1%). There are 58 people who contact with the hazards of uranium production are in the main production facilities, and 9 people who do not contact with harmful factors are in the additional production facilities. The most common pathology is pathology of vision: 68,6 per 100 employees. 3% of 100 workers have pathology of respiratory diseases. Prevalence of the circulatory system - 22,3%, nervous system diseases - 8,95%, 7,46% of the digestive system, diseases of the blood-7,46%, and other -5,97%. Health status of the working group was estimated by the index of health, i.e. on the basis of the percentage of healthy workers. The index of health among workers at a uranium production is 83,2% of persons per 100 workers. 41 patients-89% of workers were revealed with diseases of the eye and adnexa, 5 of them (10,86%) have an experience more than 5 years in secondary production facilities. With an experience more than 5 years hyperopia increases.

  3. Curative radio therapy in elderly patients with endometrial cancer. Patterns of relapse, toxicity and quality of life

    International Nuclear Information System (INIS)

    Purpose: To assess survival, disease-specific survival, acute and late toxicity and quality of life in patients with curable endometrial carcinoma treated with adjuvant or primary radiotherapy at the age ≥75 years. Patients and methods: In a prospective study, outcome was regularly assessed in 49 patients treated between 1991 and 1995 at a median age of 78.4 years. Radiotherapy was applied using the same concept as in younger patients. Thirty-eight patients received postoperative adjuvant radiotherapy (vaginal insertions only: n=18; external and vaginal insertions: n=17; external radiotherapy only: n=3), 8 patients were treated for a vaginal recurrence. Three patients received primary radiotherapy. Median pelvic dose was 39.6 Gy (ICRU) with 1.8 Gy per fraction (4 fields). Vaginal HDR radiotherapy consisted of 5 times 5 Gy at 0.5 cm depth in cases with no external radiotherapy, and of 3 times 5 Gy in addition to pelvic radiotherapy, respectively. Median follow-up was 3.2 years. The EORTC QLQ-C30 was used for self-assessment of quality of life. Results: Survival and disease-specific survival at 5 years was 64% and 84%, respectively. There was no pelvic or vaginal recurrence in patients with Stage IA to IIB. Patients with positive adnexa and those treated for vaginal recurrence relapsed in 50%. Two patients (4%) did not complete radiotherapy because of severe diarrhea. Grade 4 late complications were observed in 1/38 patients following adjuvant radiotherapy and in 2/8 patients treated for a recurrence. The actuarial rate of Grade 3 to 4 complications was 7% at 3 years. Quality of life was good in most cases and remained constant over time. (orig.)

    Skin and skin adnexa toxicities are the most common side effects associated with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) and occur in most patients receiving this therapy. The majority of these cutaneous side effects are transient, reversible, and dose dependent. Although these symptoms are in general not severe, they significantly affect quality of life and can have a serious effect on treatment compliance as well as the treatment regimen. The most common early symptoms present as papulopustules on an erythematous base, usually localized in seborrheic areas. This clinical presentation is commonly described as "acneiform", although these adverse reactions have clinical presentations, such as rosacea-like and seborrheic-like dermatitis. In this context, we report a case of a 77-year-old man with a medical history of planocellular lung cancer with ipsilateral pulmonary metastasis and mediastinum infiltration who received erlotinib as a third-line therapy, presenting with centrofacial rosaceiform rash as a side effect associated with the use of EGFR-TKIs. The patient had a negative previous history of rosacea. Therefore, symptoms probably occurred as an adverse reaction due to the oncological therapy. Current terminology of early cutaneous adverse reactions caused by EGFR-TKIs refers to "acneiform" or "papulopustular" lesions, excluding less common side effects such as rosacea-like dermatitis so these symptoms might be overlooked and misdiagnosed. Thus, we would like to emphasize the importance of developing a more accurate classification of terms in order to provide early detection of all possible cutaneous side effects, including less common ones, providing specific and timely treatment, and allowing continuation of drug therapy.

    Full Text Available Abdominal tuberculosis (TB can be of various forms including peritoneal TB, tuberculous lymphadenopathy, gastrointestinal TB and visceral TB. The potential pathway includes direct spread to the peritoneum from infected adjacent foci, including the fallopian tubes or adnexa, or psoas abscess, secondary to tuberculous spondylitis. The exact stimulus for the inflammatory reaction is not known, but some suggest that it may arise due to a subclinical primary viral peritonitis, as an immunological reaction to gynaecological infections, or due to retrograde menstruation. The diagnosis of extra pulmonary TB can be difficult as it presents with nonspecific clinical and radiological features and requires high degree of suspicion for diagnosis. The abdominal TB, which is not so commonly seen as pulmonary TB, can be a source of significant morbidity and mortality and is usually diagnosed late due to its nonspecific clinical presentation. Approximately 15%-25% of cases with abdominal TB have concomitant pulmonary TB. Hence, it is quite important in identifying these lesions with high index of suspicion especially in endemic areas. Post and ndash; operative period in such patients is not smooth. They include prolonged hospital stay, enterocutaneous fistulae requiring re-operation upon failed conservative management, mortality associated with re-exploration, late complication being incisional hernia. Here we report a case of large incisional hernia following a laparotomy performed for non-resolving sub-acute intestinal obstruction which turned out to have tubercular origin later. The present case was managed by meshplasty using component separation technique (CST. [Int J Reprod Contracept Obstet Gynecol 2015; 4(5.000: 1666-1668

  6. Skin lesions in European hibernating bats associated with Geomyces destructans, the etiologic agent of white-nose syndrome.

    Full Text Available White-nose syndrome (WNS has claimed the lives of millions of hibernating insectivorous bats in North America. Its etiologic agent, the psychrophilic fungus Geomyces destructans, causes skin lesions that are the hallmark of the disease. The fungal infection is characterized by a white powdery growth on muzzle, ears and wing membranes. While WNS may threaten some species of North American bats with regional extinction, infection in hibernating bats in Europe seems not to be associated with significant mortality. We performed histopathological investigations on biopsy samples of 11 hibernating European bats, originating from 4 different countries, colonized by G. destructans. One additional bat was euthanized to allow thorough examination of multiple strips of its wing membranes. Molecular analyses of touch imprints, swabs and skin samples confirmed that fungal structures were G. destructans. Additionally, archived field notes on hibernacula monitoring data in the Harz Mountains, Germany, over an 11-year period (2000-2011 revealed multiple capture-recapture events of 8 banded bats repeatedly displaying characteristic fungal colonization. Skin lesions of G. destructans-affected hibernating European bats are intriguingly similar to the epidermal lesions described in North American bats. Nevertheless, deep invasion of fungal hyphae into the dermal connective tissue with resulting ulceration like in North American bats was not observed in the biopsy samples of European bats; all lesions found were restricted to the layers of the epidermis and its adnexae. Two bats had mild epidermal cupping erosions as described for North American bats. The possible mechanisms for any difference in outcomes of G. destructans infection in European and North American bats still need to be elucidated.

    Full Text Available Leprosy (Hansen’s disease is a chronic granulomatous infectious disease that primarily affects the peripheral nerves, skin, upper respiratory tract mucosa, eyes and certain other tissues. It is diagnosable and curable if recognized early and treated adequately. A twenty nine-year-old male from Jessore, Bangladesh reported in Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh with the complaints of multiple erythematous, large, raised and circumscribed lesions with loss of sensations on different parts of the body, especially distal portions of all four limbs for last eight months. Subsequently he developed ulcers on the anesthetic fingers due to smoking and few ulcerative lesions on both feet. Skin examination revealed multiple erythematous, large nodular lesions on both sides of the cheek and forehead, multiple erythematous, indurated, large plaques with raised margin and central clearing on the trunk, waist and all four limbs, few satellite lesions around the large plaques on the trunk, few hypopigmented patches and plaques on buttock and lower limbs, multiple painless ulcers on dorsal surface of fingers of both hands, both lateral malleoluses and right sole. On examination of peripheral nerves, left great auricular nerve, both ulnar nerves and both common peroneal nerves were moderately enlarged and tender. Slit skin smear for AFB (modified Z-N stain was done and revealed that there were large number of acid and alcohol-fast bacilli arranged in straight and curved parallel bundles with globular masses (cigar-bundle appearance, morphologically resembling Mycobacterium leprae. Skin biopsy for histopathological examination revealed extensive infiltration of macrophages in the dermis, separated from epidermis by narrow grenz zone, with destruction of skin adnexa. Few foci of poorly defined granuloma in dermis were also noted. The patient was managed with rifampicin, clofazimine, dapsone, prednisolone and omeprazole.

    Chikungunya virus (CHIKV) is transmitted when infected mosquito probes the host skin. While probing, mosquito saliva is expectorated into host skin along with virus which contains cocktail of molecules having anti-hemostatic and immunomodulatory properties. As mosquito saliva is a critical factor during natural arboviral infection, therefore we investigated mosquito saliva induced cutaneous events that modulate CHIKV infection. The effect of mosquito saliva on CHIKV infection was examined through inoculation of suckling mice subcutaneously with either CHIKV alone or uninfected mosquito bite followed by CHIKV. Histopathological evaluation of skin revealed infiltration of transmigrated inflammatory cells. Dermal blood vessels were hyperemic and adnexa showed degenerating lesions. Severe hemorrhage was observed in dermis and hypodermis in mosquito bite+CHIKV group compared to CHIKV group. Analysis of cytokines in skin showed significant downregulation of inflammatory genes like TLR-3, IL-2, IFN-γ, TNF-α and IFN-β in mosquito bite+CHIKV group compared to CHIKV group. In contrast, significant upregulation of anti-inflammatory genes like IL-4 and IL-10 was observed. These early events might have been responsible for increased dissemination of CHIKV to serum and peripheral organs as demonstrated through >10-fold higher viremia, antigen localization, cellular infiltration and degenerative changes. Thus mosquito saliva induced early cellular infiltration and associated cytokines augment CHIKV pathogenesis in a mouse model. This mosquito improved CHIKV mouse model simulates the realistic conditions that occur naturally during infected mosquito bite to a host. It will lead to better understanding of CHIKV pathobiology and promote the evaluation of novel medical countermeasures against emerging CHIKV. PMID:26925703

    Full Text Available Abstract Background The Danish Veterinary Cancer Registry (DVCR was established in May 2005 to gather information about neoplasms in the Danish dog and cat populations. Practitioners from more than 60 clinics throughout Denmark have submitted data on these species. The objectives of the current study were, with a special focus on mast cell tumours (MCT to investigate the occurrence, gender distribution, biological behaviour, locations, types, the diagnostic method used and treatment of skin neoplasms in dogs based on information reported to the DVCR. Methods From May 15th 2005 through February 29th 2008, reports on a total of 1,768 canine cases of neoplasia in the skin, subcutis or adnexa were submitted. Of these, 765 cases (43% were confirmed by cytology or histopathology. Results The majority of dogs had a benign neoplasm (66% while 21% were cases of malignant neoplasia. The most commonly encountered malignant neoplasms were MCT and soft tissue sarcomas and for benign neoplasms, lipomas and histiocytomas were the most common. The location of the neoplasms were primarily in the cutis, subcutis or in the perianal region. The occurrence, gender distribution, biological behaviour and location of canine skin neoplasias in Denmark were similar to earlier reports, although some national variations occurred. A correlation between grade of MCT and the proportion of cases treated surgically was observed. Conclusions Population based cancer registries like the DVCR are of importance in the collection of non-selected primary information about occurrence and distribution of neoplasms. The DVCR provides detailed information on cases of skin neoplasms in dogs and may serve as a platform for the study of sub-sets of neoplastic diseases (e.g. MCT or subgroups of the canine population (e.g. a specific breed.

  10. An Umbilical/Paraumbilical Hernia as a Sign of an Intraabdominal Malignancy in the Elderly

    Full Text Available The umbilical area can present with a variety of signs associated with an intra abdominal malignancy. An umbilical/paraumbilical hernia might itself be a sign of an internal malignancy. The correlation between the presence of an umbilical/paraumbilical hernia and an intra abdominal malignancy has been previously based only on case reports. The aim of the study was to evaluate the significance of an umbilical/paraumbilical hernia as a symptom of an intraabdominal malignancy. Material and methods. A retrospective analysis was performed; review of the medical records of 145 patients (113 female and 32 male; mean age 66.4±11.9 with an umbilical/paraumbilical hernia treated during the period of 2005-2013. Twenty-three patients (15.9% were diagnosed with an intra abdominal malignancy; 34% were in the age group over 75 years of age. Results. The most common malignancies were: colorectal cancer, followed by pancreatic cancer, and cancers of the adnexa and kidneys. The patients with a concomitant malignancy identified were significantly older than those without a malignancy. In 65% of patients, the diagnosis was made postoperatively. Logistic regression analysis demonstrated that age, the presence of preoperative symptoms, anemia, and weight loss were independent risk factors for concomitant abdominal cancer. Conclusion. The findings of this study support intensive preoperative diagnostic evaluation of elderly patients that are qualified for surgery for an umbilical/paraumbilical hernia. This is particularly important because most of these patients had a small/medium hernia orifice, which did not allow for accurate manual abdominal exploration. Currently, the routine preoperative diagnostic evaluation is often insufficient for an accurate diagnosis

The differential diagnosis is difficult and occasionally definite diagnosis cannot be established even after clinical and histopathological findings are taken together. We describe a case of a middle-aged man who presented with a 10-year history of voluminous eyelid swelling with concomitant late-onset atopic manifestations, namely bronchial asthma and allergic rhinitis with nasal polyps. After thorough clinical and laboratory investigation, including a biopsy of the eyelid, we classified the patient’s disease to a rare entity that has been relatively recently described: periocular xanthogranuloma associated with adult-onset asthma. In a review of the literature, no prospective trials concerning the treatment of this disease were found. The literature mainly contained case reports and case series in which corticosteroids and chemotherapy with alkylating agents have been reported to be beneficial. We treated our patient with a combination of oral corticosteroids and cyclophosphamide pulses and we observed substantial regression of the eyelid masses together with a normalization of systemic immunologic abnormalities.Keywords: periocular xanthogranuloma, adult-onset asthma, non-Langerhans histiocytoses, cyclophosphamide, methylprednisolone

    White-nose syndrome (WNS) is a cutaneous fungal disease of hibernating bats associated with a novel Geomyces sp. fungus. Currently, confirmation of WNS requires histopathologic examination. Invasion of living tissue distinguishes this fungal infection from those caused by conventional transmissible dermatophytes. Although fungal hyphae penetrate the connective tissue of glabrous skin and muzzle, there is typically no cellular inflammatory response in hibernating bats. Preferred tissue samples to diagnose this fungal infection are rostral muzzle with nose and wing membrane fixed in 10% neutral buffered formalin. To optimize detection, the muzzle is trimmed longitudinally, the wing membrane is rolled, and multiple cross-sections are embedded to increase the surface area examined. Periodic acid-Schiff stain is essential to discriminate the nonpigmented fungal hyphae and conidia. Fungal hyphae form cup-like epidermal erosions and ulcers in the wing membrane and pinna with involvement of underlying connective tissue. In addition, fungal hyphae are present in hair follicles and in sebaceous and apocrine glands of the muzzle with invasion of tissue surrounding adnexa. Fungal hyphae in tissues are branching and septate, but the diameter and shape of the hyphae may vary from parallel walls measuring 2 ??m in diameter to irregular walls measuring 3-5 ??m in diameter. When present on short aerial hyphae, curved conidia are approximately 2.5 ??m wide and 7.5 ??m in curved length. Conidia have a more deeply basophilic center, and one or both ends are usually blunt. Although WNS is a disease of hibernating bats, severe wing damage due to fungal hyphae may be seen in bats that have recently emerged from hibernation. These recently emerged bats also have a robust suppurative inflammatory response.

  13. Fullerenol C60(OH)24 nanoparticles decrease relaxing effects of dimethyl sulfoxide on rat uterus spontaneous contraction

    International Nuclear Information System (INIS)

    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.

  15. The local origin of decidual cells in pregnant mice

    International Nuclear Information System (INIS)

    In order to evaluate the participation of extrauterine cells in the formation of mouse antimesometrial decidua, [3H]-thymidine was administered ip on days 1, 5 and 6 of pregnancy and the animals were killed 1 h afterwards. A second group of mice received four ip injections of [3H]-thymidine at 6-h intervals on the 1st day of pregnancy and were killed on the 2nd, 5th or 6th day of pregnancy. A third group of virgin mice in estrus received [3H]-thymidine ip four times at 6-h intervals and was killed 96 h after the first injection. Radioautographs of the uteri showed that few endometrial stomal cells were labelled on the 1st and 2nd day of pregnancy. Although many decidual cells incorporated thymidine on the 5th and 6th day of pregnancy in pulse-labelled animals, only few labelled decidual cells were found on the 5th and 6th day of pregnancy in animals that received several injections of thymidine on the 1st and 2nd day of pregnancy. These results indicate that the antimesometrial decidual cells that develop at the beginning of pregnancy are mostly of local origin. The short-term migration of extraneous cells into the uterus to participate in decidualization is not supported by these data. (author)

  16. Provision of a simplified methodology for determining estradiol and progesterone receptors in human breast tumours. Internal and external quality control

    International Nuclear Information System (INIS)

    A simplified assay for the detection of progesterone receptors (PR) in human breast tissue is described. Tissue storage is at -20 deg. C rather than -70 deg. C and a centrifugation speed of 20,000 rpm avoids requirement of an ultracentrifuge. Cytosol preparations obtained from homogenized oestradiol benzoate primed wistar rat uteri performed satisfactorily as positive controls with stability of two months in liquid nitrogen. The use of iodinated tracer (progesterone 11 alpha glucuronide 125 I iodotyramine) proved disappointing in the progesterone receptor assay in contrast to 125I oestradiol which worked well in a oestrogen receptor assay, previously developed. Hydroxyl-apatite was a better separating agent than dextran coated charcoal in both assays and yielded better sensitivity, particularly when protein concentrations were low. Five breast cancer specimens assayed yielded, by Scatchard analysis, Kd values between 12 to 22x10-9 m|h, comparable to the positive controls. However, two of these had binding site capacity of less than 5 fmol/mg cytosol as compared to the three others and the positive controls where values ranged from 47-196 fmol/mg cytosol. 28 refs, 6 figs, 14 tabs

  18. Should Deceased Donation be Morally Preferred in Uterine Transplantation Trials?

    In recent years much research has been undertaken regarding the feasibility of the human uterine transplant (UTx) as a treatment for absolute uterine factor infertility (AUFI). Should it reach clinical application this procedure would allow such individuals what is often a much-desired opportunity to become not only social mothers (via adoption or traditional surrogacy arrangements), or genetic and social mothers (through gestational surrogacy) but mothers in a social, genetic and gestational sense. Like many experimental transplantation procedures such as face, hand, corneal and larynx transplants, UTx as a therapeutic option falls firmly into the camp of the quality of life (QOL) transplant, undertaken with the aim, not to save a life, but to enrich one. However, unlike most of these novel procedures - where one would be unlikely to find a willing living donor or an ethics committee that would sanction such a donation - the organs to be transplanted in UTx are potentially available from both living and deceased donors. In this article, in the light of the recent nine-case research trial in Sweden which used uteri obtained from living donors, and the assertions on the part of a number of other research teams currently preparing trials that they will only be using deceased donors, I explore the question of whether, in the case of UTx, there exist compelling moral reasons to prefer the use of deceased donors despite the benefits that may be associated with the use of organs obtained from the living.

    Sand tiger sharks (Carcharias taurus) have an unusual mode of reproduction, whereby the first embryos in each of the paired uteri to reach a certain size ('hatchlings') consume all of their smaller siblings during gestation ('embryonic cannibalism' or EC). If females commonly mate with multiple males ('behavioural polyandry') then litters could initially have multiple sires. It is possible, however, that EC could exclude of all but one of these sires from producing offspring thus influencing the species genetic mating system ('genetic monogamy'). Here, we use microsatellite DNA profiling of mothers and their litters (n = 15, from two to nine embryos per litter) to quantify the frequency of behavioural and genetic polyandry in this system. We conservatively estimate that nine of the females we examined (60%) were behaviourally polyandrous. The genetic mating system was characterized by assessing sibling relationships between hatchlings and revealed only 40 per cent genetic polyandry (i.e. hatchlings were full siblings in 60% of litters). The discrepancy stemmed from three females that were initially fertilized by multiple males but only produced hatchlings with one of them. This reveals that males can be excluded even after fertilizing ova and that some instances of genetic monogamy in this population arise from the reduction in litter size by EC. More research is needed on how cryptic post-copulatory and post-zygotic processes contribute to determining paternity and bridging the behavioural and genetic mating systems of viviparous species.

    All the major components of the WNT signalling pathway are expressed in female germ cells and embryos. However, their functional relevance in oocyte biology is currently unclear. We examined ovaries collected from TCFGFP mice, a well-known Wnt reporter mouse model, and found dynamic changes in the Wnt/βcatenin signalling activity during different stages of oocyte development and maturation. To understand the functional importance of Wnt signalling in oocytes, we developed a mouse model with the germ cell-specific constitutive activation of βcatenin using cre recombinase driven by the DEAD (Asp-Glu-Ala-Asp) box protein 4 (Ddx4) gene promoter. Histopathological and functional analysis of ovaries from these mutant mice (Ctnnb1ex3cko) showed no defects in ovarian functions, oocytes, ovulation and early embryonic development. However, breeding of the Ctnnb1ex3cko female mice with males of known fertility never resulted in birth of mutant pups. Examination of uteri from time pregnant mutant females revealed defects in ectoderm differentiation leading to abnormal foetal development and premature death. Collectively, our work has established the role of active WNT/βcatenin signalling in oocyte biology and foetal development, and provides novel insights into the possible mechanisms of complications in human pregnancy such as repeated spontaneous abortion, sudden intrauterine unexpected foetal death syndrome and stillbirth.

    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 The most commonly reported mullerian duct anomalies are septate, arcuate, didelphys, unicornuate or hypoplastic uteri. Here we describe a presentation of unusual mullerian anomaly. We report a case of 31 year old nulliparous woman with primary infertility married since 5 years with history of excision of longitudinal vaginal septum 2 years back. Clinical examination revealed two cervix. On ultrasound, she was diagnosed with single fundus with 2 uterine cavities and double cervix with complete septum within. Diagnosis was confirmed with hysterosalpingogram and MRI showing no communication between the two uterine cavities. On combined laproscopy and hysteroscopy, the septum was excised above the level of cervix transforming into a single cavity uterus with free bilateral spillage of fallopian tubes, keeping the two cervix intact. This anomaly is inconsistent with generally accepted understanding of mullerian development but fits within alternative hypothesis. Establishing an accurate diagnosis is essential for planning treatment and management strategies. [Int J Reprod Contracept Obstet Gynecol 2015; 4(6.000: 2065-2068

  3. Concomitant chemobrachyradiotherapy with ifosfamide and cisplatin followed by consolidation chemotherapy in locally advanced squamous cell carcinoma of the uterine cervix: Results of a phase II study

    International Nuclear Information System (INIS)

    Purpose: To evaluate the efficacy and toxicity of ifosfamide and cisplatin administered concomitantly with low-dose-rate brachytherapy followed by consolidation chemotherapy in the treatment of locally advanced squamous cell cervical carcinoma (LASCC). Methods and materials: Forty-four patients with biopsy-proven LASCC were enrolled. FIGO Stages IB2 bulky to IVA were entered into this study. Patients were assigned to receive external radiotherapy (50 Gy in 25 fractions); then ifosfamide 2 g/m2 plus cisplatin 75 mg/m2 was applied during two low-dose-rate brachytherapy applications, and 4 cycles of consolidation chemotherapy with the same drug combination were given after completion of radiotherapy. The planned dose to point A was 85 Gy. Results: All patients received both courses of concomitant chemobrachytherapy and at least 1 cycle of consolidation chemotherapy. The average duration of radiation was 45.1 days. The clinical complete response rate was 100%. Grade 3 and 4 leukopenia occurred in 25% and 11% of the cycles, respectively. After a median follow-up of 34 months (range, 20-54 months), the recurrence-free and the overall survival rates were 84% and 91%, respectively. Major delayed local complications occurred in 7 cases (16%). Conclusions: These results indicate that concomitant chemobrachyradiotherapy with ifosfamide and cisplatin is a feasible combination for patients with LASCC of the cervix uteri. A randomized trial is planned

  4. Hypointensity on postcontrast MR imaging from compression of the sacral promontory in enlarged uterus with huge leiomyoma and adenomyosis

    International Nuclear Information System (INIS)

    In patients with huge leiomyoma and with adenomyosis of the uterus, a peculiar area of hypointensity was occasionally observed on postcontrast magnetic resonance (MR) imaging in the dorsal portion of the enlarged uterus near the sacral promontory. We describe the imaging characteristics of these MR findings and correlate them with histopathological findings to examine whether the areas represent specific pathological changes. Ten patients with huge leiomyomas and two with huge adenomyotic lesions whose imaging revealed the hypointensity were enrolled. All had enlarged uteri that extended beyond the sacral promontory. MR findings of the hypointense areas were evaluated and correlated with histopathological findings in 5 patients with leiomyoma and two with adenomyosis who had hysterectomy. The ten patients with leiomyoma showed flare-shaped hypointensity arising from the dorsal surface of the uterine body that extended deep into the tumor. The base of the hypointense areas was narrow in 5 patients with intramural leiomyoma and broad in five with subserosal leiomyoma. Two patients with adenomyosis showed nodular-shaped areas of hypointensity in front of the sacral promontory. Precontrast T1- and T2-weighted MR images showed no signal abnormalities in the portions corresponding to the hypointensity in any of the 12 patients. Pathological examinations showed no specific findings in the portions corresponding to the hypointensity in the 7 patients who had hysterectomy. The areas of hypointensity may represent functional changes, such as decreased localized blood flow caused by compression of the sacral promontory. (author)

    AIM: To evaluate the potential usefulness of transcatheter uterine artery embolization as a treatment for symptomatic adenomyosis in patients without uterine fibroids. MATERIALS AND METHODS: Uterine artery embolization using polyvinyl alcohol particles sized 250-710 mm was performed in 43 patients (mean; 40.3 years, range; 31-52 years) with dysmenorrhoea, menorrhagia, or bulk-related symptoms (pelvic heaviness, urinary frequency) due to adenomyosis without fibroids. All patients underwent pre-procedural and 3.5 months (range 1-8 months) follow-up magnetic resonance imaging (MRI) with contrast enhancement. Clinical symptoms were also assessed at the time of MRI before and after embolization. RESULTS: Significant improvement of dysmenorrhoea (95.2%) and menorrhagia (95.0%) was reported in most patients. Contrast-enhanced MRI revealed non-enhancing areas suggesting coagulation necrosis of adenomyosis in 31 patients (72.1%), decreased size without necrosis in 11 patients (25.6%), and no change in one patient (2.3%). The mean volume reduction of the uteri after uterine artery embolization was 32.5% (from 321.7{+-}142.9 to 216.7{+-}130.1 cm{sup 3}). CONCLUSION: Transcatheter uterine artery embolization is an effective therapy for the treatment of symptomatic pure adenomyosis, and may be a valuable alternative to hysterectomy.

    The endometrial-myometrial interface (EMI) is a specific functional region of uterus. However, our knowledge on EMI ultrastructure both in normal uterus and adenomyosis is far from enough to understand its pathology. In this study, used the samples of EMI and outer myometrium (OM) from the adenomyosis hysterectomy specimens and the subjects from the control uteri, we prospectively compared the ultrastructure of myocytes from EMI and OM, the ultrastructural changes of EMI between the proliferative and secretory phases, and the ultrastructural difference of EMI between adenomyosis and the control group. In both adenomyosis and control group, there were differences in ultrastructure between myocytes from EMI and OM. Specifically, the myocytes from EMI were rich in organelles. In contrast, the myocytes from OM had abundant contractile structural components. In the proliferative phase, the myocytes from EMI in adenomyosis had significantly smaller cell and nucleus diameter than those from the control group, but in the secretory phase, the difference was not significant. In the control group, the various ultrastructural features of myocytes from EMI including the mean diameter of cell and nuclei and the myofilaments/cytoplasm ratio exhibited cyclical changes, but in adenomyosis, the normal cyclical changes were absent. In conclusions, there are significant ultrastructural differences between the myocytes from EMI and OM. The myocytes in women with adenomyosis were significantly different to the control subjects, primarily because the normal cyclical changes were absent. PMID:24817942

    Background. High prevalence of autoantibodies to the calcium-binding, endoplasmic reticulum chaperone protein calreticulin has been reported in various autoimmune and parasitic diseases. It has been reported that adenomyosis is associated with the presence of autoantibodies, in particular to phospholipids; however, it is not known whether it is associated with autoimmunity to calreticulin. Results. A 35-year-old gravida 4 para 4 woman presented with a history of many years of intractable menorrhagia. Histopathological examination of a subsequent hysterectomy specimen revealed a bulky uterus, a poorly developed secretory endometrium with decidualization of the stroma and chronic endometritis, as well as the presence of adenomyosis uteri. IgG autoantibodies to calreticulin were measured in the plasma of this and 234 other patients. Nine (3.8%) patients tested positive. The titer of anticalreticulin IgG autoantibody in the sole case with adenomyosis was approximately 8 times the average of other positive-testing samples. Conclusions. The etiology of adenomyosis is unclear. The presence of a high titer, blocking anticalreticulin autoantibody may directly increase the risk that adenomyosis might develop. It is also possible that the expansion of endometrial glandular tissue, as well as elevated estrogens, during adenomyosis may lead to elevated calreticulin, which induces an autoimmune reaction to it. Further study is required to determine whether there is a significant association between adenomyosis and the prevalence of calreticulin autoantibodies. PMID:26425587

  9. Arterial Distribution of Calibrated Tris-Acryl Gelatin and Polyvinyl Alcohol Embolization Microspheres in Sheep Uterus

    International Nuclear Information System (INIS)

    The purpose of this study was to compare, after embolization, the distribution in the uterine arterial vasculature of tris-acryl gelatin microspheres (TGMS) and polyvinyl alcohol microspheres (PVAMS). A limited bilateral uterine artery embolization was performed in six adult sheep under fluoroscopic control by injecting in each uterine artery 0.25 ml of 500- to 700-μm TGMS of PVAMS suspended in 50/50 saline/contrast medium. Sacrifices were performed 1 week after embolization and uteri were analyzed histologically. The number and size of microspheres and vessels were measured, as well as the histological location according to a classification in four zones of the uterus. One hundred sixty-five vessels (69 vessels occluded with TGMS and 96 vessels occluded with PVAMS) were measured. The size of the occluded vessels decreased significantly from proximal to distal zones of the uterine vasculature (P < 0.0001). The location of TGMS and PVAMS within the vasculature was significantly different (P < 0.0001) since PVAMS blocked significantly more distally than TGMS. Deformation of the microspheres within the tissue was greater for PVAMS (18.0% ± 12.3%) than for TGMS (8.7% ± 9.2%) (P < 0.0001). In conclusion, PVAMS have a more distal distribution in the sheep uterine vasculature, compared to TGMS. Such differences in partition, already described in the kidney embolization model, can ultimately explain the different clinical outcome reported with these two types of microspheres in uterine fibroid embolization.

    Full Text Available Objective: Investigation of unpredictable risks due to abnormal uterine pathology after the choice of uterus-preserving reconstructive surgical procedure for women who have uterine prolapse and no other complaints was aimed. Methods: The data of 121 women (105 postmenopausal and 16 premenopausal who underwent vaginal hysterectomy due to pelvic organ prolapse was examined and the post-hysterectomy histopathology results were evaluated. Results: Senile cystic atrophy was the most common endometrial pathology result among postmenopausal women (63.5%. However, proliferative and secretory endometrium was the most common endometrial pathology finding among premenopausal women (81.3%. There were statistically significant differences between postmenopausal and perimenopausal women in terms of these pathology results (p0.05, myoma uteri was significantly more common in patients with perimenopause (p=0.01. Conclusion: The uterus must be evaluated in terms of endometrial pathologies in asymptomatic women with pelvic organ prolapse before uterus-preserving reconstructive surgical procedure, especially in postmenopausal period.

    2013-01-01

    Full Text Available Objectives. This study observes therapeutic efficacy of uterine artery embolization combined with MTX infusion which terminates cesarean scar pregnancy (CSP and induces three factors which probably relate to failure. Methods. Twenty-three CSP patients were treated with combined uterine artery MTX infusion and embolization. Among them six patients with severe hemorrhage were immediately treated with interventional operation. Clinical effects were estimated by symptoms, serum -hCG, ultrasound, and MR. Results. Interventional treatments were technologically successful in 22 patients except one. Immediate hemostasis was achieved in all 6 patients with massive colporrhagia. No occurrence of infection and uterine necrosis was observed, but 12 women suffered abdominal pains. Nineteen patients’ uteri were preserved, whereas four underwent hysterectomy eventually. Conclusions. Transcatheter arterial chemoembolization is effective to treat high-risk CSP in preference to hysterectomy. To achieve more successful outcomes, three factors should be highlighted: adequate MTX dosage, appropriate embolic material, and complete embolization of target arteries that supply blood to embryo in the scar.

  12. Further studies on the effect of radiation during the storage of frozen 8-cell mouse embryos at -196 deg C

    International Nuclear Information System (INIS)

    Frozen 8-cell mouse embryos were treated with radiation doses of 0, 10, 50, 100 or 200 cGy γ-rays at a dose rate of approx. 5 cGy/day. After thawing the embryos were scored for normal morphological appearance and for development to morulae and blastocysts after 24 h in culture. Embryos from each treatment were then separately transferred to the uteri of pseudopregnant foster mothers which were killed at Day 14 of pregnancy. There was no effect of radiation on morphological appearance, development to morulae and blastocysts, implantation rate, or on the ratio of live fetuses to the number of transferred embryos. As there appeared to be no detrimental effect of up to 200 cGy on frozen 8-cell mouse embryos and, as this is the equivalent of approx. 2000 years of background radiation, it is concluded that normal levels of background radiation would not be a hazard to the long-term storage of mammalian embryos.

  13. Pain management in cancer cervix

    2005-01-01

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

    Full Text Available Abstract Background The objective of this study was to assess trends in cancer mortality by educational level in Barcelona from 1992 to 2003. Methods The study population comprised Barcelona inhabitants aged 20 years or older. Data on cancer deaths were supplied by the system of information on mortality. Educational level was obtained from the municipal census. Age-standardized rates by educational level were calculated. We also fitted Poisson regression models to estimate the relative index of inequality (RII and the Slope Index of Inequalities (SII. All were calculated for each sex and period (1992–1994, 1995–1997, 1998–2000, and 2001–2003. Results Cancer mortality was higher in men and women with lower educational level throughout the study period. Less-schooled men had higher mortality by stomach, mouth and pharynx, oesophagus, larynx and lung cancer. In women, there were educational inequalities for cervix uteri, liver and colon cancer. Inequalities of overall and specific types of cancer mortality remained stable in Barcelona; although a slight reduction was observed for some cancers. Conclusion This study has identified those cancer types presenting the greatest inequalities between men and women in recent years and shown that in Barcelona there is a stable trend in inequalities in the burden of cancer.

  15. Free-living nematode species (Nematoda) dwelling in hydrothermal sites of the North Mid-Atlantic Ridge

    2015-12-01

    Morphological descriptions of seven free-living nematode species from hydrothermal sites of the Mid-Atlantic Ridge are presented. Four of them are new for science: Paracanthonchus olgae sp. n. (Chromadorida, Cyatholaimidae), Prochromadora helenae sp. n. (Chromadorida, Chromadoridae), Prochaetosoma ventriverruca sp. n. (Desmodorida, Draconematidae) and Leptolaimus hydrothermalis sp. n. (Plectida, Leptolaimidae). Two species have been previously recorded in hydrothermal habitats, and one species is recorded for the first time in such an environment. Oncholaimus scanicus (Enoplida, Oncholaimidae) was formerly known from only the type locality in non-hydrothermal shallow milieu of the Norway Sea. O. scanicus is a very abundant species in Menez Gwen, Lucky Strike and Lost City hydrothermal sites, and population of the last locality differs from other two in some morphometric characteristics. Desmodora marci (Desmodorida, Desmodoridae) was previously known from other remote deep-sea hydrothermal localities in south-western and north-eastern Pacific. Halomonhystera vandoverae (Monhysterida, Monhysteridae) was described and repeatedly found in mass in Snake Pit hydrothermal site. The whole hydrothermal nematode assemblages are featured by low diversity in comparison with either shelf or deep-sea non-hydrothermal communities. The nematode species list of the Atlantic hydrothermal vents consists of representatives of common shallow-water genera; the new species are also related to some shelf species. On the average, the hydrothermal species differ from those of slope and abyssal plains of comparable depths by larger sizes, diversity of buccal structures, presence of food content in the gut and ripe eggs in uteri.

  16. Leakage of caesium braquitherapy sources

    International Nuclear Information System (INIS)

    In several Venezuelan public hospitals where cervix uteri tumours are treated by intracavitary radiotherapy, that use manual after loading Fletcher method, with Caesium 137 sources, the use of improper source holders, locally manufactured from pieces of drainage plastic tubing, which deteriorated and created a corrosive environment all around the sources, omission of manufacturer's recommendations regarding corrosion information, source storage, inspection and testing, violation of International Atomic Energy Agency Radiation Protection Procedures, and lack of proper regulatory control, resulted integrity damage to about sixty special form sources (ISO2919 C 63322), leakage of Cs-137 from a supposed insoluble refractory active content (caesium silicoaluminate), and contamination of applicators, floors and bedding. When the situation was detected by means removal contamination tests, after routine inspections, the sources were removed from the hospitals, decontaminated by means of immersion in 3% EDTA solution in ultrasonic bath, subjected to leaking assessment tests, and the ones that passed were placed in low cost stainless steel source holders, designed and built by the instituto Venezolano de Investigaciones Cientificas (IVIC) returned to the hospitals. The leaking sources were removed from use and considered radioactive waste. In order to avoid the occurrence of similar situations, all the importers of such sources are now required to send them to IVIC for testing and placement in proper source holders, before they are shipped to the hospitals.

  17. Radiation-induced uterine changes: MR imaging

    International Nuclear Information System (INIS)

    To assess the capability of magnetic resonance (MR) imaging to demonstrate postirradiation changes in the uterus, MR studies of 23 patients who had undergone radiation therapy were retrospectively examined and compared with those of 30 patients who had not undergone radiation therapy. MR findings were correlated with posthysterectomy histologic findings. In premenopausal women, radiation therapy induced (a) a decrease in uterine size demonstrable as early as 3 months after therapy ended; (b) a decrease in signal intensity of the myometrium on T2-predominant MR images, reflecting a significant decrease in T2 relaxation time, demonstrable as early as 1 month after therapy; (c) a decrease in thickness and signal intensity of the endometrium demonstrable on T2-predominant images 6 months after therapy; and (d) loss of uterine zonal anatomy as early as 3 months after therapy. In postmenopausal women, irradiation did not significantly alter the MR imaging appearance of the uterus. These postirradiation MR changes in both the premenopausal and postmenopausal uteri appeared similar to the changes ordinarily seen on MR images of the nonirradiated postmenopausal uterus

    Implantation is a crucial step in human reproduction. Disturbances of this process are responsible for pregnancy failure after both in vivo and in vitro fertilization. The endometrium provides the implanting embryo with a unique substratum where the embryo communicates with biochemical signals, attaches itself, penetrates and grows without blood circulation. The highly proliferative phase of the cytotrophoblast, during early human embryogenesis, may be due to endogenous production of growth factors that may establish autocrine/short range paracrine stimulator loops which explain the tumor-like properties of these tissues. Endometrial BM penetration and stroma invasion may be due to the proteolytic capability of the human embryo. It is suggested that collagenase and the urokinase-like plasminogen activator are responsible for this activity. To clarify the molecular mechanisms involved in human embryo implantation several models are suggested: culture of blastocysts, culture of endometrial cells, and endometrial explant co-culture. Human blastocysts cultured with whole perfused human uteri make it possible to recognize some aspects of the entire implantation process and give us the possibility of improving the benefits provided by new technologies in reproductive medicine and reducing embryonic loss at an early stage.

METHODS: Forty 3-month-old rats were randomly divided into 5 groups: sham group,Ova group, Tcl group (1.2 mg@kg-1@d-1), Tc2 group (4.8 mg@kg-1@d-1), and estrone group (1.48 mg@kg-1@d-1), oral fedfor 3 months. The proximal tibia metaphyses were processed undecalcified for quantitative bone histomorphometryand the soft tissues were processed in paraffin for pathological observation. RESULTS: Placebo-treated (lactose)Ova rats were characterized by trabecular area (TA) decreasing and their architecture worsening compared withsham controls, and bone resorption was over formation with high bone turnover. The uteri were atrophy. (2) Inestrone-treated group, TA and trabecular numbers were significantly increased and the trabecular separation de-creased vs Ova group. Estrone slowed down Ova-inducing bone high turnover. But the size, weight, and theendometrium of the uteri in this group were increased vs Ova group. (3) TA was increased in both Tcl and Tc

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

    International Nuclear Information System (INIS)

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

    1979-06-01

    Blastocysts which developed from two-cell mouse embryos in culture tubes containing an atmosphere with 20% oxygen had approximately 20% fewer blastomeres than blastocysts which developed under an oxygen concentration of 5%. When these smaller blastocysts were transferred to the uteri of pseudopregnant foster mothers, the foetuses developing were as viable as those developing from blastocysts cultured under 5% oxygen, indicating their ability to regulate for a lower blastomere number by at least day 17 of development. The transfer operation itself had no adverse effect on foetal or placental growth. However, culture of blastocysts in vitro did depress foetal though not placental growth, suggesting that the inner cell mass is more susceptible than the trophectoderm to culture in vitro. Foetal but not placental growth was lower following the transfer of blastocysts to a day-3 rather than a day-4 uterus. Four cases of placental fusion were found. In one case, the foetuses were contained within the same embryonic sac and may have been twins. PMID:508209

    Ionizing radiations severely interfere with normal embryonic or fetal development, although period of late fetal development in mammals is considered to be the somewhat radioresistant. Here, an attempt is made to check the radiation induced developmental anomalies by vitamins during fetal development period. For this purpose, pregnant Swiss albino mice were exposed to 0.50 Gy gamma radiation during fetal growth period (day 14.25 post-coitus) in the presence (experimental) or absence (control) of vitamin B complex (20 mg/kg b.w.) till term. All dams were sacrificed on day 18 post-coitus and their uteri were examined to study reproductive status and anatomical abnormalities of each conceptus. About 48% pregnant females of the control group showed a complete embryonic resorption while in the experimental group the number of females showing resorption was only 33%. Resorption of embryos, fetal mortality and reduction in placental weight were significantly increased in mice irradiated in the absence of vitamin B complex. Various gross malformations including skeletal anomalies were significantly reduced in 18 days old fetuses given vitamin B complex therapy. Further, such fetuses had better ossification of skull and vertebrae. Sex-ratio of the fetuses, however, remained unaltered in both groups as compared to normal. (orig.)

    Paget's disease, described by Sir James Paget in 1874, is classified as mammary and extramammary. The mammary type is rare and often associated with intraductal cancer (93-100% of cases). It is more prevalent in postmenopausal women and it appears as an eczematoid, erythematous, moist or crusted lesion, with or without fine scaling, infiltration and inversion of the nipple. It must be distinguished from erosive adenomatosis of the nipple, cutaneous extension of breast carcinoma, psoriasis, atopic dermatitis, contact dermatitis, chronic eczema, lactiferous ducts ectasia, Bowen's disease, basal cell carcinoma, melanoma and intraductal papilloma. Diagnosis is histological and prognosis and treatment depend on the type of underlying breast cancer. Extramammary Paget's disease is considered an adenocarcinoma originating from the skin or skin appendages in areas with apocrine glands. The primary location is the vulvar area, followed by the perianal region, scrotum, penis and axillae. It starts as an erythematous plaque of indolent growth, with well-defined edges, fine scaling, excoriations, exulcerations and lichenification. In most cases it is not associated with cancer, although there are publications linking it to tumors of the vulva, vagina, cervix and corpus uteri, bladder, ovary, gallbladder, liver, breast, colon and rectum. Differential diagnoses are candidiasis, psoriasis and chronic lichen simplex. Histopathology confirms the diagnosis. Before treatment begins, associated malignancies should be investigated. Surgical excision and micrographic surgery are the best treatment options, although recurrences are frequent. PMID:25830993

    Full Text Available The ovine cervix is irregularly shaped, making it a challenge to pass through it during artificial insemination. Thus, the aim of this study was to describe the morphological characteristics of the cervix of Santa Ines breed, comparing the phases of the estrous cycle. A total of 112 uteri were collected from non-pregnant ewes and silicone was injected into the lumen of the cervix in order to obtain a cast of the cervical canal. Mean length of the cervix was 41.33 ± 16.38 mm and the most frequent cervical ostium type found was the duck-beak (46%. Two rings were the minimum and seven were the maximum found in the cervix, with means of 4.70 ± 1.05 rings. Morphometric data from each cervical ring indicates that the inner circumference tapers in the middle portion and then becomes to enlarge again. No significant difference (p> 0.05 was found when comparing the luteal and follicular phases, or the types of cervix regarding to the values of the diameter of the folds, height, inside circumference, midpoint between the folds and distance from the opening to the folds. Under the studied conditions, we concluded that the development of semen applicator should take into account the morphometric limits found, although the morphology and morphometry of the ovine cervix is quite varied, with no standard patterns for the species, even when comparing the luteal and follicular phases.

    Four young Nile crocodiles (Crocodylus niloticus) were infected with infective pentastome larvae obtained from naturally infected Mozambique bream, Oreochromis mossambicus, and red-breasted bream, Tilapia rendalli swierstrai in the Kruger National Park. At day 95 post infection one of the crocodiles died and three female and four male S. wedli were recovered from its lungs. One pair was found in copula but the uteri of the females were not yet developed. Males and females were of about equal size. After 226 d post infection the three remaining crocodiles were sacrificed. Two of these harboured no pentastomes but eight were taken from the lungs of the third. The sex ratio had shifted in favour of the females, seven females and one male being present. One of the females recovered from the crocodiles was placed in saline and produced 3,400 eggs. These were used to infect eight guppies, Poecilia reticulata. Within 31 d two infective stages of S. wedli had developed in one of the guppies thus completing the life-cycle of the pentastome. S. wedli recovered from experimentally infected final hosts were slightly smaller than those recovered from a wild-caught final host. PMID:10192834

    A 9-month-old Yorkshire terrier was admitted to the clinic because of abnormal sexual behaviour and clitoral hypertrophy. External examination confirmed standard development of caudal genital organs: vagina, vulva and cervix uteri. Serum profile of gonadotropin hormones 17 β-estradiol (system. Gonads resembling testicles, structures indicating epididymis and rudimentary deferent ducts were resected, along with adherent part of the uterus. Cytogenetic analysis showed a male chromosomal complement 78, XY in all metaphases of the studied Yorkshire terrier dog. The chromosomal constitution was confirmed by fluorescence in situ hybridisation (FISH) with whole-chromosome painting probes specific for chromosomes X and Y, as well as by polymerase chain reaction (PCR) amplification of the 271-bp Y-linked fragment of SRY (the sex-determining region on the Y chromosome) gene. Sequencing of the dog's SRY gene coding region did not reveal any mutation. To search for potential mutation in the SOX9 gene (Sry-box containing gene 9), which is considered to be one of the key genes involved in the sex determination process, the PCR fragments of exons 1, 2 and 3 originating from the canine patient were sequenced in order to compare with both male and female healthy control dogs. In the analysed regions of the SOX9 gene, no mutation was found. PMID:23378246

    Neorickettsiaspp. are bacterial endosymbionts of parasitic flukes (Digenea) that also have the potential to infect and cause disease (e.g., Sennetsu fever) in the vertebrate hosts of the fluke. One of the largest gaps in our knowledge ofNeorickettsiabiology is the very limited information available regarding the localization of the bacterial endosymbiont within its digenean host. In this study, we used indirect immunofluorescence microscopy to visualizeNeorickettsiasp. within several life cycle stages of the digeneanPlagiorchis elegans Individual sporocysts, cercariae, metacercariae, and adults ofP. elegansnaturally infected withNeorickettsiasp. were obtained from our laboratory-maintained life cycle, embedded, sectioned, and prepared for indirect immunofluorescence microscopy using anti-Neorickettsiaristiciihorse serum as the primary antibody.Neorickettsiasp. was found within the tegument of sporocysts, throughout cercarial embryos (germ balls) and fully formed cercariae (within the sporocysts), throughout metacercariae, and within the tegument, parenchyma, vitellaria, uteri, testes, cirrus sacs, and eggs of adults. Interestingly,Neorickettsiasp. was not found within the ovarian tissue. This suggests that vertical transmission ofNeorickettsiawithin adult digeneans occurs via the incorporation of infected vitelline cells into the egg rather than direct infection of the ooplasm of the oocyte, as has been described for other bacterial endosymbionts of invertebrates (e.g.,RickettsiaandWolbachia).

    Polyamines are key regulators in cell growth and differentiation. It has been shown that ornithine decarboxylase (Odc) was essential for post-implantation embryo development, and overexpression of spermidine/spermine N1-acetyltransferase will lead to ovarian hypofunction and hypoplastic uteri. However, the expression and function of polyamine-related genes in mouse uterus during early pregnancy are still unknown. In this study we investigated the expression, regulation, and function of polyamine-related genes in mouse uterus during the peri-implantation period. Odc expression was strongly detected at implantation sites and stimulated by estrogen treatment. The expression of Odc antizyme 1 and spermidine/spermine N1-acetyltransferase was also highly shown at implantation sites and regulated by Odc or polyamine level in uterine cells. Embryo implantation was significantly inhibited by alpha-difluoromethylornithine, an Odc inhibitor. Moreover, the reduction of Odc activity caused by alpha-difluoromethylornithine treatment was compensated by the up-regulation of S-adenosylmethionine decarboxylase gene expression. Collectively, our results indicated that the coordinated expression of uterine polyamine-related genes may be important for embryo implantation. PMID:18202119

    Mating-induced endometritis (MIE) is ubiquitous in the horse after natural mating and artificial insemination with frozen/thawed semen causing the most aggressive response. The majority of mares eliminate MIE 24-48 h after insemination. An endometrial explant culture was tested as a potential in vitro exemplar for sperm-induced MIE. Endometrial prostaglandin F(2alpha) (PGF(2alpha)) secretion and expression of interleukin-8 (IL-8) were used as markers of inflammation. Endometrial explants were cultured from uteri collected from follicular phase mares. Explants were challenged with 1 or 10 x 10(6) sperm/ml frozen/thawed semen, chilled semen, washed sperm or seminal plasma. Medium was collected 24 and 72 h after challenge and assayed for PGF(2alpha) by radioimmunoassay. Treatment of endometrial explants with frozen/thawed, chilled semen or washed sperm did not change the secretion of PGF(2alpha) compared with untreated controls. However, 24 h after challenge cultured explants expressed IL-8. The in vitro endometrial explant system did not represent the in vivo response to semen when PGF(2alpha) was used as a marker of inflammation, yet the use of gene expression as an inflammatory marker warrants further investigation.

    The Notch signaling pathway is critical for the differentiation of many tissues and organs in the embryo. To study the consequences of Notch1 gain-of-function signaling on female reproductive tract development, we used a cre-loxP strategy andAmhr2-cretransgene to generate mice with conditionally activated Notch1 (Rosa(Notch1)). TheAmhr2-cretransgene is expressed in the mesenchyme of developing female reproductive tract and in granulosa cells in the ovary. Double transgenicAmhr2-cre, Rosa(Notch1)females were infertile, whereas controlRosa(Notch1)mice had normal fertility. All female reproductive organs in mutants showed hemorrhaging of blood vessels progressing with age. The mutant oviducts did not develop coiling, and were instead looped around the ovary. There were multiple blockages in the lumen along the oviduct length, creating a barrier for sperm or oocyte passage. Mutant females demonstrated inflamed uteri with increased vascularization and an influx of inflammatory cells. Additionally, older females developed ovarian, oviductal, and uterine cysts. The significant change in gene expression was detected in the mutant oviduct expression ofWnt4, essential for female reproductive tract development. Similar oviductal phenotypes have been detected previously in mice with activatedSmoand inbeta-catenin,Wnt4,Wnt7a, andDicerconditional knockouts, indicating a common regulatory pathway disrupted by these genetic abnormalities.

Estrogenic effects of aqueous extracts of leaves of Holarrhena fl oribunda have been evaluated by uterotrophic assay. Ovariectomized mice were used and treated subcutaneously during seven days with 50, 100, 200 mg.kg-1 doses of Holarrhena fl oribunda and with 100, 200 mg.kg-1 doses of Holarrhena fl oribunda plus 25 mg.kg-1 of oestradiol 17-β. Estrogenic activity was analysed by uterine dry and wet weight, surrenal gland wet weight, vaginal opening, protein and cholesterol level in uteri horn. Administration of extracts to the doses of 100 and 200 mg.kg-1 exhibits increase of uterine dry and wet weight, surrenal gland wet weight, vaginal opening, protein levels and decrease of level of cholesterol in uterine horn. The results suggest that, aqueous extracts of Holarrhena fl oribunda possesses estrogenic type effect. But when 100 and 200 mg.kg-1 of Holarrhena fl oribunda were given alone with 25 mg.kg-1 of estradiol 17-β, the estrogenic effect was slight. These results supposed that H. fl oribunda is a weak phytoestrogen and the aqueous extracts of the leaves behad as partial agonistic

    The success of embryo implantation is a critical step towards further embryo development and pregnancy outcome.The observations and investigations on embryo implantation have been over a century.A huge body of knowledge has been accumulated in anatomy,histology,ultrastructure and hormonal regulation; as well as recently in depth information about molecular signaling pathways got from studies of genomic wide gene screening and specific gene deletion.The knowledge from basic research has also substantially helped to initiate and improve the Artificial Reproductive Technology (ART) in clinical applications.Now we've known that the normal embryo implantation involves the embryo's development into an implantation-competent blastocyst and the synchronized transformation of uteri into a receptive stage.The interdependent relationship between the blastocyst and uterus involves complicated hormonal regulation and local paracrine,juxtacrine interactions.In this paper,we review some important historical findings regarding uterine receptivity and blastocyst activation,as well as some less discussed topics such as embryo spacing,embryo orientation.Further understandings on detailed mechanisms during the process of embryo implantation will help cure women infertility as well as develop new generation of non-steroids contraceptives.

    The oviducts of superovulated Kunming white females were flushed 44-46 hours after treatment with human chorionic gonadotropin to collect 1074 late two-cell-stage embryos.The embryos were placed twenty at a time between two platinum electrodes laid 1 mm apart in 0.3M mannitol in the electrode chamber.The blastomeres were fused by a short electric pulse(80V for 50μsec) applied by a pulse generator.Fusion of blastomeres was usually completed in 20-60minutes.After 25 hours of culture,most of the tetraploid embryos developed to the four-cell stage.Zonae pellucidae of 387 four-cell-stage tetraploid embryos were removed by treatment with acid Tyrode's buffer.The embryos were plated on an ES cell layer,After 40 hours of coculture,248 embryos aggregated with ES cells were collected and transferred into the uteri of twenty four 2.5-day pseudopregnant recipinets.Ten recipients were pregnant.but no live fetuses were born.Three pregnant recipients were routinely subject to a Caesarean section on day 18 of pregnancy and seven abnormal fetuses were obtained.The results demonstrate that ES cells derived from C57BL/6 mice are pluripotential to a certain extent.

    Uterine vascular changes, critical for pregnancy success, occur at each implant site during endometrial decidualization. Mesometrial decidualization recruits high numbers of angiogenic, uterine Natural Killer (uNK) cells that trigger midpregnancy spiral arterial remodeling. We postulated that uNK cells contribute to early decidual angiogenesis as endothelial-cell extrinsic sources of Delta-like ligand 1 (DLL1), a molecule that induces endothelial tip cell differentiation and orthogonal vascular growth in other tissues. Virgin uteri expressed Dll1 mesometrially and anti-mesometrially and relative expression increased in both anatomic regions as pregnancy progressed. Analyses of transcripts from gd10.5 uNK cells flow sorted on the basis of expression of Dolichos biflorus agglutinin (DBA) lectin revealed that DBA+ but not DBA- uNK cells expressed Dll1. Immunostaining at gd4.5 found DLL1-expressing cells rare. At gd6.5, DBA+ uNK cells at all stages of maturation expressed DLL1. By gd10.5, DLL1 immunoreactivity was strongly expressed by some but not all DBA+ uNK cells and more weakly by DBA- cells. DLL1+ cells were mesometrially stratified and concentrated within central decidua basalis. Our data suggest that uNK cells have the potential to induce endothelial tip cell differentiation and to promote non-planar vascular growth within early decidua basalis. PMID:23284862

    The most significant increase in metabolic syndrome over the previous decade occurred in women of reproductive age, which is alarming given that metabolic syndrome is associated with reproductive problems including subfertility and early pregnancy loss. Individuals with metabolic syndrome often consume excess fructose, and several studies have concluded that excess fructose intake contributes to metabolic syndrome development. Here, we examined the effects of increased fructose consumption on pregnancy outcomes in mice. Female mice fed a high-fructose diet (HFrD) for 6 weeks developed glucose intolerance and mild fatty liver but did not develop other prominent features of metabolic syndrome such as weight gain, hyperglycemia, and hyperinsulinemia. Upon mating, HFrD-exposed mice had lower pregnancy rates and smaller litters at midgestation than chow-fed controls. To explain this phenomenon, we performed artificial decidualization experiments and found that HFrD consumption impaired decidualization. This appeared to be due to decreased circulating progesterone as exogenous progesterone administration rescued decidualization. Furthermore, HFrD intake was associated with decreased bone morphogenetic protein 2 expression and signaling, both of which were restored by exogenous progesterone. Finally, expression of forkhead box O1 and superoxide dismutase 2 [Mn] proteins were decreased in the uteri of HFrD-fed mice, suggesting that HFrD consumption promotes a prooxidative environment in the endometrium. In summary, these data suggest that excess fructose consumption impairs murine fertility by decreasing steroid hormone synthesis and promoting an adverse uterine environment. PMID:26677880

  17. Combination of irradiation, carcinostatics, and urokinase for the treatment of uterine cervical carcinoma

    International Nuclear Information System (INIS)

    In the treatment of carcinoma of the cervix uteri, histological changes were studied by dividing patients into 2 groups. One group was treated with radio-therapy and the other was treated with radiotherapy combined with chemotherapy, using antineoplastic agents which were used alone or in combination with urokinase. In regard to radiotherapy alone, Linac 10 MeV x-ray, 60Co-teletherapy, and radium contiguous irradiation were evaluated, and marked changes in cancerous parenchyma were seen with irradiation over 3000 rad. Irradiation of 3000 rad caused destruction of cancer cells, separation of the cells, inclusion of the focus, necrosis of hyalinization, and infiltration of neutrophils and lymphocytes. Approximately 4000 rad caused hyperplasia of the interstitial connective tissues, in addition to the above-mentioned changes. Approximately 5000 rad caused destruction and disappearance of cancer tissues, and approximately 6000 rad caused disappearance of the cancer cells which were then only connective or necrostic tissues. When radiotherapy was combined with BLM and FAMT therapies, degenerative changes were observed in many cases with irradiation of 1200 - 2400 mgh of radium or 1000 - 3000 rad of Linac or 60Co. The addition of urokinase tended to further accelerate the degeneration begun by BLM therapy. (Tsunoda, M.)

    Germline SMARCB1 mutations predispose in schwannomatosis patients to the development of multiple benign schwannomas and, in some cases, meningiomas. Here, we report on a 34-year-old female patient who developed multiple schwannomas at various locations and in addition a leiomyoma of the cervix uteri. She carried a c.362+1G>A mutation that inactivates the donor splice site of exon 3. This mutation caused the schwannomatosis phenotype in this patient and was also demonstrated to be present in her affected mother. The leiomyoma displayed the genetic features that are characteristic for germline SMARCB1 mutation-associated tumors. The mutant allele retained in the tumor, whereas the wild-type allele was lost by loss of heterozygosity. Furthermore, the loss of heterozygosity involved net loss of chromosome 22. An NF2 mutation was not found. However, quantitative polymerase chain reaction suggested that both NF2 copies were lost in the tumor. Immunostaining with a SMARCB1 antibody revealed the mosaic expression pattern that is typical for schwannomatosis-associated tumors. To our knowledge, this is the first reported case of leiomyoma associated with a germline SMARCB1 mutation. As such, it widens the spectrum of benign tumors associated with a germline SMARCB1 mutation. PMID:24525513

    Full Text Available Isoflavones are soy phytoestrogens that potentially exert various favorable effects in postmenopausal women, for example, alleviating vasomotor episodes, attenuating bone loss, and stimulating vaginal epithelial maturation. There has, however, been lack of consensus regarding those therapeutic effects. Most clinical studies of isoflavones have been conducted with women who had undergone natural menopause, but not those who had undergone surgical menopause. This study reports on a 51-year-old woman who presented with severe vasomotor episodes after undergoing a hysterectomy and a bilateral oophorectomy due to hypermenorrhea secondary to myoma uteri. She refused hormone therapy due to fear of adverse drug reactions so was treated with oral soy isoflavones (two capsules twice daily, equivalent to at least 100 mg daily dose for 8 weeks. The number and severity of hot flushes and her menopause-specific quality of life dramatically improved from baseline values. The serum bone resorption marker (beta C-telopeptide decreased markedly, while vaginal epithelial maturation improved slightly, suggesting the potential of isoflavones in attenuating bone loss and stimulating vaginal maturation. The intervention did not adversely affect the hormonal profile (FSH, LH, and estradiol and liver or renal functions. Thus, isoflavones could be an option for women experiencing severe vasomotor episodes after surgical menopause.

    Despite dramatic progress in infertility treatments and assisted reproduction, no effective therapies exist for complete loss of uterine structure and/or function. For such patients, genetic motherhood is possible only through gestational surrogacy or uterine transplantation. However, many ethical, social, technical and safety challenges accompany such approaches. A theoretical alternative is to generate a bioartificial uterus, which requires engineering of uterine architecture and appropriate cellular constituents. Here, rat uteri decellularization by aortic perfusion with detergents produced an underlying extracellular matrix together with an acellular, perfusable vascular architecture. Uterine-like tissues were then regenerated and maintained in vitro for up to 10 d through decellularized uterine matrix (DUM) reseeding with adult and neonatal rat uterine cells and rat mesenchymal stem cells followed by aortic perfusion in a bioreactor. Furthermore, DUM placement onto a partially excised uterus yielded recellularization and regeneration of uterine tissues and achievement of pregnancy nearly comparable to the intact uterus. These results suggest that DUM could be used for uterine regeneration, and provides insights into treatments for uterine factor infertility. PMID:25043501

    Numerous antinuclear demonstrations reveal that the public is anxious about the potential health effects caused by nuclear power plants. The purpose of this study is to address the question "Is there a higher cancer incidence rate in the vicinity of nuclear power plants in Taiwan?" The Taiwan Cancer Registry database from 1979 to 2003 was used to compare the standardized incidence rate of the top four cancers with strong evidence for radiation risks between the "plant-vicinity" with those "non-plant-vicinity" groups. All cancer sites, five-leading cancers in Taiwan, and gender-specific cancers were also studied. We also adopted different observation time to compare the incidence rate of cancers between two groups to explore the impact of the observation period. The incidences of leukemia, thyroid, lung, and breast cancer were not significantly different between two groups, but cervix uteri cancer showed higher incidence rates in the plant-vicinity group. The incidence of cervical cancer was not consistently associated with the duration of plant operation, according to a multiyear period comparison. Although there was higher incidence in cervix cancer in the plant-vicinity group, our findings did not provide the crucial evidence that nuclear power plants were the causal factor for some cancers with strong evidence for radiation risks.

  4. Evaluation of emergency transcatheter arterial embolization in intractable postpartum hemorrhage

    International Nuclear Information System (INIS)

    Objective: To assess the efficacy and safety of emergency transcatheter arterial embolization in the management of intractable postpartum hemorrhage. Methods: Twenty-five patients with intractable postpartum hemorrhage were undertaken superselective catheterization into the bilateral internal iliac arteries or uterial arteries to find the causes and sites of bleeding through DSA and then followed by arterial embolization with gelfoam particles. Result: All of the 25 patients with obstetrical bleeding were successfully controlled by TAE, the procedure lasted for 25-60 min, (mean 42.5 ± 4.6 min); with both catheterization and bleeding halt successful rates of 100%. Comparison of hemoglobin and heartbeat before and after the procedure showed significance (t=29.49, P<0.01; t=16.51, P<0.01). The uterus showed reintegration on time and menstruation resumed in all patients. Conclusions: Emergency arterial embolization is a safe and effective means for control of intractable postpartum hemorrhage, providing less trauma and no severe complications, especially as an unique management for fetal postpartum hemorrhage.

    In Nepal, while no population based cancer registry program exists to assess the incidence, prevalence, morbidity and mortality of cancer, at the national level a number of hospital based cancer registries are cooperating to provide relevant data. Seven major cancer diagnosis and treatment hospitals are involved, including the BP Koirala Memorial Cancer hospital, supported by WHO-Nepal since 2003. The present retrospective analysis of cancer patients of all age groups was conducted to assess the frequencies of different types of cancer presenting from January 1st to December 31st 2012. A total of 7,212 cancer cases were registered, the mean age of the patients being 51.9 years. The most prevalent age group in males was 60-64 yrs (13.6%), while in females it was 50-54 yrs (12.8%). The commonest forms of cancer in males were bronchus and lung (17.6%) followed by stomach (7.3%), larynx (5.2%) and non Hodgkins lymphoma (4.5%). In females, cervix uteri (19.1%) and breast (16.3%), were the top ranking cancer sites followed by bronchus and lung (10.2%), ovary (6.1%) and stomach (3.8%). The present data provide an update of the cancer burden in Nepal and highlight the relatively young age of breast and cervical cancer patients. PMID:26745133

  6. Classification of the 16,471 patients treated by radiation therapy from 1962 to 1986, and crude five-year survival rates of patients in each category of radiotherapy treatment from 1962 to 1978 in the National Cancer Center Hospital

    International Nuclear Information System (INIS)

    The summation and classification of patients registered for planned radiation therapy in the 24-year period from 1962 to 1986, in the Department of Radiation Therapy, National Cancer Center Hospital, are reported. Patients numbered 16,471, and total sessions of treatment were 26,175. The ratio of the two figures, 1.58, is the average number of treatment sessions per patient. Peak age was 61 - 65 years' old and 56 - 60 years old, respectively for males and females. The most frequent primary site of disease for radiation therapy was the head and neck, followed by trachea, bronchus and lung, crevix uteri, breast, and esophagus. Frequency of squamous cell carcinoma was 38.0 %; that of adenocarcinoma was 20.9 %. Radical treatment was performed in 32.0 % of patients in the first session, but this figure decreased to 24.7 % for all sessions. There were many cases of secondary and primary palliative treatment, i.e., 31.8 %. Radiotherapy was done in 70 % of patients by megavoltage X-ray, with 9.4 % treated by electron beam. Crude 5-year survival rates for each classification of malignant disease respective to the category of treatment policy from 1962 to 1978 were obtained. Among the radical treatment group, head and neck tumors, skin cancer, and Hodgkin's disease showed 5-year survival rates greater than 50 %. (author)

    Iron oxide nanoparticles (NPs) are commonly utilized for biomedical, industrial, and commercial applications due to their unique properties and potential biocompatibility. However, little is known about how exposure to iron oxide NPs may affect susceptible populations such as pregnant women and developing fetuses. To examine the influence of NP surface-charge and dose on the developmental toxicity of iron oxide NPs, Crl:CD1(ICR) (CD-1) mice were exposed to a single, low (10 mg/kg) or high (100 mg/kg) dose of positively-charged polyethyleneimine-Fe₂O₃-NPs (PEI-NPs), or negatively-charged poly(acrylic acid)-Fe₂O₃-NPs (PAA-NPs) during critical windows of organogenesis (gestation day (GD) 8, 9, or 10). A low dose of NPs, regardless of charge, did not induce toxicity. However, a high exposure led to charge-dependent fetal loss as well as morphological alterations of the uteri (both charges) and testes (positive only) of surviving offspring. Positively-charged PEI-NPs given later in organogenesis resulted in a combination of short-term fetal loss (42%) and long-term alterations in reproduction, including increased fetal loss for second generation matings (mice exposed in utero). Alternatively, negatively-charged PAA-NPs induced fetal loss (22%) earlier in organogenesis to a lesser degree than PEI-NPs with only mild alterations in offspring uterine histology observed in the long-term.

    Bovine tritrichomonosis is a sexually transmitted disease caused by the protozoon Tritrichomonas foetus and characterised by embryonic-death and abortion. During pregnancy, the processes of cell proliferation and death play a crucial role for blastocyst implantation and the subsequent maintenance of early pregnancy, and their misbalance may lead to the abortion. In this study, we aimed to investigate whether cell proliferation and death may be altered during tritrichomonosis. For this purpose, we used pregnant BALB/c mice as an alternative experimental animal model that has successfully reproduced the infection. We analysed the immunohistochemical expression of active caspase-3 and proliferating cell nuclear (PCNA) antigens in the endometrium of infected mice. We found an increase in the number of caspase-3 positive cells in infected mice that were not pregnant at the necropsy. Besides, the number of positive proliferating cells increased in the uterine luminal epithelium of infected animals killed at 5-7 days post coitum (dpc). Pregnant infected mice killed at 8-11 dpc showed higher proliferation than control animals. We suggest that the cytopathic effect induced by T. foetus in the uteri of infected mice may induce the apoptosis of the epithelial cells and, as a result, promote a compensatory proliferative response. The information described here will be helpful to further study the pathogenesis of the bovine tritrichomonosis. PMID:26028409

    Equine herpesvirus (EHV)-1 induces respiratory infection, neurological disorders and abortion in horses. Most of the currently available attenuated or inactivated vaccines against this infection are administered intramuscularly and only provide partial protection against the respiratory disease. The present study examines the effect of intranasal immunization with purified EHV-1 recombinant glycoprotein D (gD) in BALB/c mice followed by challenge with three different EHV-1 strains during early to mid-pregnancy. The induced viral infection was evaluated by virus isolation, DNA detection by polymerase chain reaction, histopathology and immunohistochemical localization of antigen in the lung, placenta and uterus. Non-immunized mice showed clinical signs of infection, positive virus isolation from lungs and uteri, and abortion induced by one of the virus strains. Endometrial lesions developed in some of these animals that have been described previously only in horses. Immunized mice and their offspring had no viral infection or typical lesions. Intranasally administered gD therefore induced partial or complete protection against three different EHV-1 strains in BALB/c mice. PMID:25124330

  10. An overview of exposure to, and effects of, petroleum oil and organochlorine pollution in Grey seals (Halichoerus grypus)

    International Nuclear Information System (INIS)

    Most incidences involving oil pollution of grey seals (Halichoerus grypus) seem to have occurred at the breeding sites. Because of the high concentration of animals at this time, even small oil spills will pollute many animals. As a result of chronic low-level pollution from coastal ship traffic and discharges from offshore petroleum activity in the North Sea, 50% of the grey seal pups at the largest breeding colony in Norway are polluted each year by oil. This oil pollution, as well as other cases of spills at breeding colonies, shows that oil produced little visible disturbance to the seals' behaviour and there is little mortality. The effects and mortality may, however, be more serious following a spill of crude oil, where animals may be affected by inhalation of toxic volatile compounds. High body burdens of PCBs and DDTs seem to have caused skull-bone lesions and occlusions of the uteri in grey seals in the Baltic Sea. Exposure to these persistent compounds has also been suspected to be the cause of reduction in the population of Baltic grey seals. There are indications that thyroid hormone and vitamin A status of grey seal pups are affected by the low exposure concentrations experienced at the Norwegian coast (1/20 of the concentration detected in grey seal pups from the Baltic Sea). This gives serious cause for concern about the effects that chronic low-level exposure to persistent organochlorine pollutants may have on individuals and on populations of grey seals

    Full Text Available Abstract Background The aim of this study was to identify factors associated with cancer screening practices and with general attitudes toward cancer screening in a general population. Methods Mailed survey of 30–60 year old residents of Geneva, Switzerland, that included questions about screening for five cancers (breast, cervix uteri, prostate, colon, skin in the past 3 years, attitudes toward screening, health care use, preventive behaviours and socio-demographic characteristics. Cancer screening practice was dichotomised as having done at least one screening test in the past 3 years versus none. Results The survey response rate was 49.3% (2301/4670. More women than men had had at least one cancer screening test in the past 3 years (83.2% vs 34.5%, p Conclusion Attitudes play an important role in cancer screening practices among middle-aged adults in the general population, independent of demographic variables (age and sex that determine in part screening recommendations. Negative attitudes were the most frequent among men and the most socio-economically disadvantaged. The moderate participation rate raises the possibility of selection bias.

    Full Text Available The basic component of Silastic® glue (Dow Corning used to prepare Silastic® pellets is polydimethylsiloxane. This compound is also present in other commercial adhesives such as FASTIX® (Akapol SA that are available in any store for that category. In the present study we developed low cost, easy to prepare handmade steroid pellets (HMSP by mixing 17β-estradiol, progesterone or other synthetic steroids with FASTIX® adhesive. We assessed serum levels of 17β-estradiol, progesterone, prolactin and luteinizing hormone in ovariectomized mice treated for 24 and 48 h or 7, 14 and 28 days with 20 µg or 5 mg of 17β-estradiol or 5 mg progesterone HMSP. We found a time dependent and significant increase in the levels of both natural hormones, and a downregulation of serum luteinizing hormone levels, while both 17β-estradiol doses increased serum prolactin. Uterine weights at sacrifice and histological examination of the uteri and the mammary glands correlated with estrogen or progestin action. Finally, we evaluated the biological effects of HMSP compared to commercial pellets or daily injections in the stimulation or inhibition of hormone dependent mammary tumor growth, and found that HMSP were as effective as the other methods of hormone administration. These data show that HMSP represent a useful, low cost, easily accessible method for administering steroids to mice.

    Ichthyocephalus anadenoboli n. sp. ( Rhigonematidae ; Nematoda) from Anadenobolus politus ( Porat ) ( Rhinocricidae ; Diplopoda ) from Guadeloupe is described. The new species most closely resembles I. egleri since both sexes are of approximately the same size and the spicules are markedly unequal; it is distinguished in having a much longer right spicule, by the form of the extremity of the left spicule and by the presence of a vaginal sac opening into the vagina at its junction with the uteri. In addition certain aspects of spermiogenesis in the new species are studied. Maturation of spermatids occurs in two phases, one in the testis and seminal receptacle of males, the second in the vaginal sac in females. The second phase involves profound changes in form as well as nuclear transformation. It is suggested that the vaginal sac observed in certain species of Rhigonema as well as the " bourse copulatrice " of certain Tetrameres spp. and Maupasina weissi , like that of Ichthyocephalus anadenoboli , are specialized to accommodate the final stages of spermiogenesis.

    Full Text Available INTRODUCTION: Cancer of the cervix uteri is the second most common cancer among women worldwide. The association of human papillomavirus (HPV infection with cervical carcinogenesis is well documented. This is a pilot study aiming to studying the prevalence and the pattern of Human Papilloma Virus Type 16 (HPV16 by immunostaining in the tissues of cervical carcinomas of Ethiopian women. METHODS: 20 specimens of uterine cervical carcinomas were studied histopathologically and immunohistochemically for HPV16. RESULTS: Histologically the specimens were classified as: Ten cases were Non Keratinized Squamous cell carcinoma (NKSCC, six cases were Keratinized Squamous Cell Carcinoma (KSCC and four cases were Adenocarcinoma (ADC. Immunohistochemistry study showed positivity in eleven cases (55%; seven cases (35% were non-keratinized squamous cell carcinoma; three cases (15% were keratinized squamous cell carcinoma and one case (5% belonged to the adenocarcinomas. CONCLUSION: This study reveals a significant detection of HPV in Ethiopian women by the use of advanced techniques such as Immunohistochemistry (IHC. The data of this study suggested that the marked expression of the HPV 16 was in the less differentiated uterine cervix carcinomas

    Data from 20 years of cancer registration in Harare (Zimbabwe) are used to investigate the risk of cancer in the white population of the city (of European origin), relative to that in blacks (of African origin). In the absence of information on the respective populations-at-risk, we calculated odds of each major cancer among all cancers, and took the odds ratios of whites to blacks. Some major differences reflect obvious phenotypic differences (the very high incidence of skin cancer-melanoma and nonmelanoma--in the white population), whereas others (high rates of liver cancer, Kaposi sarcoma and conjunctival cancers in blacks) are the result of differences in exposure to infectious agents. Of particular interest are cancers related to lifestyle factors, and how the differences in risk are changing over time, as a result of evolving lifestyles. Thus, the high risk of cancers of the esophagus and cervix uteri in blacks (relative to whites) and colorectal cancers in whites show little change over time. Conversely, the odds of breast cancer, on average four times higher in whites than blacks, has shown a significant decrease in the differential over time. Cancer of the prostate, with the odds initially (1991-1997) 15% higher in whites had become 33% higher in blacks by 2004-2010. PMID:26437451

  16. Value Of Three Dimensional Power Doppler Ultrasound In Prediction Of Endometrial Carcinoma In Patients With Postmenopausal Bleeding

    International Nuclear Information System (INIS)

    Objective: to determine whether endometrial volume or power Doppler indices as measured by 3D ultrasound imaging can discriminate between benign and malignant endometrium in women with postmenopausal bleeding and endometrial thickness > 5 mm. Study design: Eighty-four patients with postmenopausal bleeding and endometrial thickness > 5 mm underwent 3D power Doppler ultrasound examination of the corpus uteri. The endometrial volume was calculated, along with the vascularisation index (VI), flow index and vascularisation flow index (VFI) in the endometrium. The gold standard was the histological diagnosis of the endometrium. Results: There were 56 benign and 28 malignant endometrial. Endometrial thickness and volume were significantly larger in malignant than in benign endometrial, and flow indices in the endometrium were Significantly higher. The area under the ROC curve (AUC) of endometrial thickness was 0.83, that of endometrial volume 0.73, and that of the best power Doppler variable FI 0.93. The best logistic regression model for predicting malignancy contained the variables endometrial thickness and FI. Its AUC was 0.93. Conclusion: the diagnostic performance of endometrial volume measured by 3d imaging with regard to discriminating between benign and malignant endometrium was not superior to that of endometrial thickness measured by 2D ultrasound examination, but 3D power Doppler flow indices are good diagnostic tool in predicting endometrial carcinoma

  17. A case of adenocarcinoma occurred at site of radiated double-barrel sigmoid colostomy

    International Nuclear Information System (INIS)

    A 60-year-old female developed an adenocarcinoma at the site of double-barrel sigmoid colostomy. She underwent a total hysterectomy and the subsequent radiation therapy due to carcinoma uteri when she was 34 years old. She had rectal stenosis one year later and underwent sigmoid colostomy. She had been healthy thereafter, however, when she was 58 years old, she noticed an elevated lesion at the site of colostomy. Biopsy revealed well-differentiated adenocarcinoma, so surgery was recommended but she refused it. Two years later, the entire stoma became a carcinoma, which directly invaded the abdominal wall on MRI images. A bow-shaped skin incision was made and en bloc resection of the tumor, colostomy and the surrounding tissues was performed. Finally, descending colostomy in the left upper quadrant of the abdomen was reconstructed. Primary adenocarcinoma occurring at a double-barrel colostomy is very rare, and such a case may never have been reported, although there were some reports of carcinoma occurring at an end colostomy. Since the site of the present carcinoma was radiated, the radiation may contribute to this carcinogenesis, suspecting its late effect. Our surgical procedure enabled simultaneously operation of combined resection and intraabdominal manipulation, and the reconstruction site of the stoma was easily selected. (author)

    Full Text Available An unusual cause of vaginal beeding after total abdominal hysterectomy is being reported. Histopathology revealed adenomyosis uteri and bilateral ovarian cyst. On examination there was a single lump in the hypogastrium and left iliac fossa. Auscultation revealed a faint continuous hum. On digital rectal examination, a bulge was felt, while per vaginum examination revealed mucosal congestion and bulging of mucosa. Ultrasound revealed a mass posterior to the urinary bladder. Duplex study demonstrated the yin-yang sign suggestive of a pseudo-aneurysm .CT Angiography was confirmatory and demonstrated a pseudoaneurysm arising from the left internal iliac artery. Patient underwent surgery.Postoperative period was uneventful . The commonest cause of IIA aneurysm is atherosclerosis. Other causes are arteritis ,collagen vascular disease, infection, trauma. An important subgroup is young females, who have undergone difficult delivery, forceps delivery or caesarian section or abdominal hysterectomy IIA aneurysms are usually discovered incidentally on pelvic imaging for any other indication. Surgery is the mainstay of treatment but endovascular procedures are gaining ground . [Natl J Med Res 2014; 4(2.000: 181-182

  19. Effects of X-irradiation and serotonin treatment of Porton mice on the first day of pregnancy

    International Nuclear Information System (INIS)

    Porton mice were whole-body-X-irradiated with a dose of 500 R and/or serotonin-creatinine sulphate was applied in a dose of 40 mg/kg of body weight on the first day of pregnancy. On the nineteenth day of gestation,taking into consideration females in whose uteri live foetuses were observed, the increase in their body weight throughout pregnancy, the number of foetuses in the uterus, the body weight of foetuses and the placental weight were determined. As compared with controls, in X-irradiated mice there was a significantly smaller increase in body weight during gestation and number of foetuses in the uterus and their body weight was also smaller with the exception of the body weight of female foetuses. In females treated with serotonin both the body weight of foetuses and the placental weight were significantly lower. In females injected with serotonin prior to X-irradiation, in relation to those X-irradiated only, a significantly greater body weight of foetuses was observed. (author)

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

  1. Radiosensitizing effect of medroxyprogesterone acetate on endometrial cancer cells in vitro

    1984-09-15

    From clinical experience it is known that medroxyprogesterone acetate (MPA) can increase the radiosensitivity of adenocarcinomas of the corpus uteri. This study investigates this phenomenon in vitro. Primary explants of highly differentiated adenocarcinomas were irradiated with or without pretreatment with MPA and compared with an untreated control group and to a group treated with MPA only. Cell culture itself was performed on an agarose medium in order to prevent overgrowth by fibroblasts. Untreated samples formed 43 +/- 5 clones, explants treated with MPA only produced 39 +/- 5 clones, a difference which was not statistically different; samples irradiated without pretreatment produced 16 +/- 8 and samples after combined treatment 9 +/- 3 clones (all values means +/- SD). This numeric reduction of cell growth through preirradiation treatment with MPA was statistically significant. The effect of MPA as a radiosensitizer may be due to its potential to prolong the radiosensitive G2 phase of the cell cycle. This effect of MPA may be useful also in other hormone-dependent tumors.

    The fate of human tumor cells deposited in rat uteri was investigated by light microscopy of histological sections, immunohistochemistry, and scanning electron microscopy of microvascular corrosion casts. The human colonic tumor cell line LS 174 T was used as graft since it can be detected by CEA immunohistochemistry, and spayed nude rats (PVG rnu/rnu) were used as hosts, subjected to different hormonal regimens (no exogenous hormones, medroxyprogesterone acetate, 17-beta-estradiol, or the last two regimens in combination). Intrauterine deposition of a suspension of 2 x 10(6) tumor cells resulted in tumor take in 72% (21/29) of the nude rats. Endometrial growth was verified in only three animals (14%, 3/21). Extraendometrial growth, however, was found in all animals with tumor take. These observations suggest that the endometrium is comparatively resistant to growth of xenografted human colonic tumor cells. The tumor microcirculation consisted of new vessels, giving morphological evidence that tumor growth is dependent on angiogenesis and not on invasion of preexisting vessels. PMID:9236867

  3. Uterine artery embolization for the management of secondary postpartum haemorrhage associated with placenta accreta

    International Nuclear Information System (INIS)

    Aim: To evaluate the efficacy and safety of uterine artery embolization for the management of secondary postpartum haemorrhage associated with placenta accreta. Materials and methods: Between January 2005 and August 2011, 45 women with placenta accreta, which was discovered during delivery, were managed conservatively in Peking Union Medical College Hospital. They did not experience severe bleeding during delivery. Ten patients (mean age 31 ± 6.4 years) developed secondary postpartum haemorrhage and underwent uterine artery embolization. The complications, control of haemorrhage, and outcome of the placenta left inside the uterus were retrospectively reviewed. Results: All patients underwent transcatheter embolization of bilateral uterine arteries. The median time between delivery and uterine artery embolization was 11 days (range 3–76 days). The technical success rate of embolization was 100%. Bleeding was controlled in all patients during follow-up (11 ± 6.9 months; range 3–24 months), and no further bleeding occurred. One patient developed lower-extremity deep venous thrombosis after uterine artery embolization, and no other major complications occurred. The placentae that were left inside the uteri gradually decreased in size during follow-up, except in one case. Nine patients resumed normal menstruation. One patient subsequently became pregnant and had an uneventful intrauterine pregnancy carried to term. Conclusion: Uterine artery embolization is safe and effective for the management of secondary postpartum haemorrhage associated with placenta accreta.

  4. The influence of pelvic irradiation on the formation and function of the human corpus luteum

    International Nuclear Information System (INIS)

    Hormonal changes (oestradiol, progesterone, luteinizing hormone LH and follicle stimulating hormone FSH) were monitored by radioimmuno-assay techniques in a 29-year-old patient undergoing 60Co radiotherapy for cancer of the cervix uteri, stage III (total dose 6000 rad over 35 days). Ovulation occurred after 1100 rad on day 7 of the study period and was followed by the formation of a normal mature corpus luteum despite continued irradiation. The hormone levels indicated that the process of luteinization of granulosa- and theca-cells was not affected by radiation doses of at least 3000 rad, which were sufficient to eliminate permanently the oestradiol secretion of ovarian follicles. Ovarian steroids were still measurable after the patient had received almost the entire dose of 6000 rad. The secretion of ovarian steroids, although comparable to that of a normal luteal phase, did not depress pituitary function (FSH and LH). This radioresistance of corpora lutea is of little importance, since they will eventually disappear through lack of maturing follicles. However, the observation of persisting secretion of gonadotrophins in young women undergoing pelvic irradiation may sometimes raise the impression that the radiotherapeutic regimen was inadequate.

  5. Human chorionic ganodotropin binding sites in the human endometrium

    International Nuclear Information System (INIS)

    The existence of high-affinity and low-capacity specific binding sites for luteinizing hormone/human chorionic gonadotropin (hCG) has been reported in porcine, rabbit and rat uteri. The authors have identified the hCG binding sites in the human endometrium collected from 35-42-year-old ovulatory and anovulatory women. The binding characteristics of hCG to endometrial tissue preparations from ovulatory and anovulatory women showed saturability with high affinity and low capacity. Scatchard plot analysis showed the dissociation constant of specific binding sites in the ovulatory women to be 3.5x10-10 mol/l and in anovulatory women to be 3.1x10-10 mol/l. The maximum binding capacity varied considerably between ovulatory and anovulatory endometrium. Among the divalent metal ions tested Zn2+ effected a remarkable increase in [125I]hCG binding to the endometrium, whereas Mn2+ showed a marginal increase and other metal ions did not have any effect. Data obtained with human endometrium indicate an influence of the functional state of the ovary on [125I]hCG binding to endometrium. 14 refs., 3 figs

  6. The calculation of dose from photon exposures using reference human phantoms and Monte Carlo methods. Pt. 5

    International Nuclear Information System (INIS)

    There has been some evidence that cervical cancer patients who were treated by radiotherapy, had an increased incidence of second primary cancers noticeable 15 years or more after the radiotherapy. The data suggested that high dose pelvic irradiation was associated with increase in cancers of the bladder, kidneys, rectum, ovaries, corpus uteri, and non-Hodgkin's lymphoma but not leukemia (Kleinerman et al., 1982, Morton 1973). The aim of the present work is to estimate the absorbed dose, due to radiotherapy treatment for cervival cancer, to various organs and tissues in the body. Monte Carlo calculations were performed to calculate the organ absorbed doses resulting from intracavitary sources such as ovoids and applicators filled or loaded with radium, Co-60 and Cs-137. For that purpose a routine which simulates an internal source was constructed and added to the existing Monte Carlo code (GSF-Bericht S-885, Kramer et al.). Calculations were also made for external beam therapy. Various anterior, posterior and lateral fields were applied, resulting from megavoltage, Co-60 and Cs-137 therapy machines. The calculated organ doses are tabulated in three different ways: as organ dose per air Kerma in the reference field, according to the recommendations of the International Commission on Radiation Units and Measurements (ICRU Report No 38, 1985); as organ dose per surface dose and as organ dose per tissue dose at Point B.

    Full Text Available In the main experiment the total daily protein intake and quality (essential amino-acids was varied in 4 groups of mares. The incidence of oestrus in mares during the transitional period was unaffected by protein nutrition. Ovarian activity, as evaluated by follicular development and size of the ovaries, was affected. Mares that received low-quality protein (Groups 1 and 2 had a higher number of smaller follicles (<10 mm that developed during the transitional period compared to mares on a high-quality protein intake (Groups 3 and 4. The mares that received the high quality protein ovulated 2-3 weeks earlier in the breeding season in a synchronised period of 4-5 weeks compared to a period of 6-8 weeks in Groups 1 and 2. The duration of the subsequent oestrous cycles was not affected. There was no difference in the diameter of the largest follicle of mares between groups on the day before ovulation. In a separate experiment, 5 maiden Anglo-Arab mares, 4-5 years of age, were slaughtered at different stages during the anovulatory, transitional and ovulatory periods of the breeding cycle. The morphology of the ovaries and uteri of these mares was described and photographed for use as guidelines when comparing ovarian changes and follicular activity of mares.

    Full Text Available This study was aimed to establish a nomogram for uterine roundness index (UTRI for a Nigerian population. Seven hundred Nigerian girls and women in the premenarche, nulliparous, multiparous and postmenopausal groups with normal uteri were evaluated by pelvic ultrasound. The length, anteroposterior and transverse diameters of the uterus were measured and the UTRI calculated as the ratio of anteroposterior diameter to the length. The age, height, and parity of the subject were recorded. The mean UTRI +SD were 0.44457+0.0629 for premenarche, 0.5880+0.1118 for nulliparous, 0.6005+0.1046 for multiparous and 0.5269+0.1037 for postmenopausal. Pearson’s correlation analysis showed significant correlation between UTRI and age, height and weight in premenarche group and weight in the nulliparous, multiparous and postmenopausal groups (p< 0.05. Significant negative correlation between UTRI and age occurred only in the postmenopausal group (p< 0.05. The study has established a nomogram for UTRI in a Nigeria population which will be of gynaecological importance to sonographers and referring clinicians in assessing the normality of uterine shapes and contour.

    Full Text Available Fluoxetine is antidepressant drug which widely known as Prozac®, is a fluorinated methyl phenoxy derivative of phenylpropylamine. Fluoxetine is a bicyclic antidepressant that differs structurally and pharmacologically from other currently available antidepressant agents. 80 pregnant mice were administrated oral doses of Fluoxetine (0.052, 0.104 & 0.208 mg/mouse /day From 6th up to both 15th and 19th days of gestation. The pregnant mice treated with Fluoxetine HCl showed states of instability, nervousness, twitching of head, agitation, hazy movement and marked reduction in food intake as well as reduction in the body weight. The results of uteri examination of pregnant mice groups on both 15th and 19th days of gestation showed remarkable reduction in their size, dismorphology, length and number of implantation sites as well as large reduction in the number of still live embryos. Increase in the number of dead and resorbed mouse embryos was dose dependant. Also, the results showed reduction in both body weight and crown rump of mouse embryos. The treated mouse foetuses showed several malformations as diminution in size, exenocephalia and skeletal malformations.

    Paget's disease, described by Sir James Paget in 1874, is classified as mammary and extramammary. The mammary type is rare and often associated with intraductal cancer (93-100% of cases). It is more prevalent in postmenopausal women and it appears as an eczematoid, erythematous, moist or crusted lesion, with or without fine scaling, infiltration and inversion of the nipple. It must be distinguished from erosive adenomatosis of the nipple, cutaneous extension of breast carcinoma, psoriasis, atopic dermatitis, contact dermatitis, chronic eczema, lactiferous ducts ectasia, Bowen's disease, basal cell carcinoma, melanoma and intraductal papilloma. Diagnosis is histological and prognosis and treatment depend on the type of underlying breast cancer. Extramammary Paget's disease is considered an adenocarcinoma originating from the skin or skin appendages in areas with apocrine glands. The primary location is the vulvar area, followed by the perianal region, scrotum, penis and axillae. It starts as an erythematous plaque of indolent growth, with well-defined edges, fine scaling, excoriations, exulcerations and lichenification. In most cases it is not associated with cancer, although there are publications linking it to tumors of the vulva, vagina, cervix and corpus uteri, bladder, ovary, gallbladder, liver, breast, colon and rectum. Differential diagnoses are candidiasis, psoriasis and chronic lichen simplex. Histopathology confirms the diagnosis. Before treatment begins, associated malignancies should be investigated. Surgical excision and micrographic surgery are the best treatment options, although recurrences are frequent. PMID:25830993

    Uterine receptivity to embryo implantation depends on appropriate progesterone (P4) and estrogen stimulation. P4 rapidly stimulates production of the morphogen Indian hedgehog (IHH) in murine uterine epithelium as well as downstream molecules in the hedgehog pathway such as Patched homolog 1 (PTCH1) and nuclear receptor subfamily 2, group F, member 2 (NR2F2) in uterine stroma. Studies using IHH-null mice indicate that IHH is obligatory for the normal P4 response in the uterus. To determine whether IHH induction in uterine epithelium is mediated through P4 receptor (PR) in epithelium (E) and/or stroma (S), we produced tissue recombinants using uteri from neonatal PR knockout (ko) mice and wild-type (wt) mice containing PR in S and/or E or lacking PR altogether using a tissue recombinant methodology and assessed their response to P4. In tissue recombinants containing wt-S (wt-S + wt-E and wt-S + ko-E), P4 induced Ihh mRNA expression at 6 h that was 6-fold greater than in oil-treated controls (P stimulated by P4 only in recombinants containing stromal PR. These results indicate that stromal PR is both necessary and sufficient for P4 stimulation of epithelial IHH as well as downstream events such as PTCH1 and NR2F2 increases in stroma. PMID:19372202

    The objective of this work was to collect and summarize relevant literature on the anatomy, histology, and imaging of apical support of the upper vagina and the uterus provided by the cardinal (CL) and uterosacral (USL) ligaments. A literature search in English, French, and German languages was carried out with the keywords apical support, cardinal ligament, transverse cervical ligament, Mackenrodt ligament, parametrium, paracervix, retinaculum uteri, web, uterosacral ligament, and sacrouterine ligament in the PubMed database. Other relevant journal and textbook articles were sought by retrieving references cited in previous PubMed articles. Fifty references were examined in peer-reviewed journals and textbooks. The USL extends from the S2 to the S4 vertebra region to the dorsal margin of the uterine cervix and/or to the upper third of the posterior vaginal wall. It has a superficial and deep component. Autonomous nerve fibers are a major constituent of the deep USL. CL is defined as a perivascular sheath with a proximal insertion around the origin of the internal iliac artery and a distal insertion on the cervix and/or vagina. It is divided into a cranial (vascular) and a caudal (neural) portions. Histologically, it contains mainly vessels, with no distinct band of connective tissue. Both the deep USL and the caudal CL are closely related to the inferior hypogastric plexus. USL and CL are visceral ligaments, with mesentery-like structures containing vessels, nerves, connective tissue, and adipose tissue. PMID:22618209

  13. Embryotoxic effect of gamma radiation in mice and their modulation by vitamins

    International Nuclear Information System (INIS)

    Ionizing radiations severely interfere with normal embryonic or fetal development, although period of late fetal development in mammals is considered to be the somewhat radioresistant. Here, an attempt is made to check the radiation induced developmental anomalies by vitamins during fetal development period. For this purpose, pregnant Swiss albino mice were exposed to 0.50 Gy gamma radiation during fetal growth period (day 14.25 post-coitus) in the presence (experimental) or absence (control) of vitamin B complex (20 mg/kg b.w.) till term. All dams were sacrificed on day 18 post-coitus and their uteri were examined to study reproductive status and anatomical abnormalities of each conceptus. About 48% pregnant females of the control group showed a complete embryonic resorption while in the experimental group the number of females showing resorption was only 33%. Resorption of embryos, fetal mortality and reduction in placental weight were significantly increased in mice irradiated in the absence of vitamin B complex. Various gross malformations including skeletal anomalies were significantly reduced in 18 days old fetuses given vitamin B complex therapy. Further, such fetuses had better ossification of skull and vertebrae. Sex-ratio of the fetuses, however, remained unaltered in both groups as compared to normal. (orig.)

  14. An experimental study on effect of radiation in palate development of rat embryo

    International Nuclear Information System (INIS)

    The author observed morphological change in palate development of rat embryo after irradiation of x-ray on the one side of the duplex uterus. The time matings occurred between 6 p.m. and 8 a.m. and all female with copulation plugs at 8 a.m. were isolated and properly marked for evidence of copulation. The lower left abdomen of mothers were exposed to x-radiation on the 7 1/2th, 9 1/2th, 11 1/2th day of gestation, respectively 150, 250, 350, 500 rads. At 18 1/2th day of post-conception, the pregnant female were dissected and the contents of the two uteri examined. The translucent sample by Alizarin red S stain were prepared. The results were as follows; 1. The result that groups irradiated by 250 rads and 350 rads made marked difference in comparison with the control group suggests the x-ray to be an inducing factor of cleft palate. 2. At 11 1/2th day of gestation, incidence of cleft palate induced by x-irradiation was highest. 3. Mortality showed the highest frequency at 7 1/2th day of gestation, and tended to decrease according to increasing of age. 4. Morphology of cleft palate induced by x-irradiation showed similarity in comparison with those induced by other factors having been reported ever.

    Preterm premature rupture of membranes causes 40% of all preterm births, affecting 150000 women each year in the United States. Prenatal diagnostic procedures and surgical interventions increase incidence of adverse events, leading to iatrogenic membrane rupture after a fetoscopic procedure in 45% of cases. We propose an ultrathin, self-adherent, poly-L-lactic acid patch ("nanofilm") as a reparative wound closure after endoscopic/fetoscopic procedures. These nanofilms are compatible with application in wet conditions and with minimally invasive instrumentation. Ex vivo studies to evaluate the nanofilm were conducted using human chorion-amnion (CA) membranes. A custom-built inflation device was used for mechanical characterization of CA membranes and for assessment of nanofilm adhesion and sealing of membrane defects up to 3 mm in size. These ex vivo tests demonstrated the ability of the nanofilm to seal human CA defects ranging in size from 1 to 3 mm in diameter. In vivo survival studies were conducted in 25 mid-gestational rabbits, defects were created by perforating the uterus and the CA membranes and subsequently using the nanofilm to seal these wounds. These in vivo studies confirmed the successful sealing of defects smaller than 3 mm observed ex vivo. Histological analysis of whole harvested uteri 7 days after surgery showed intact uterine walls in 59% of the nanofilm repaired fetuses, along with increased uterine size and intrauterine development in 63% of the cases. In summary, we have developed an ultrathin, self-adhesive nanofilm for repair of uterine membrane defects. PMID:25549772

  16. Mortality from cancers of major sites in female radium dial workers

    International Nuclear Information System (INIS)

    The female radium dial workers have now experienced significant mortality from cancers other than the bone sarcomas and head carcinomas long known to be radium induced. The relationships of radium exposure to mortality from cancers of the stomach, pancreas, colon, rectum, liver, lung, breast, cervix, and corpus uteri, and from leukemia were studied in 1,285 pre-1930 dial workers. Mortality was compared with that expected from rates for US white females, with and without adjustment for local area mortality rates, and with mortality in dial workers exposed from 1930 to 1949. For the 693 cases whose body content of radium has been measured since 1955, dose-response relationships of cancer to systemic intake of radium and duration of employment were examined. Liver, pancreatic, cervical, and uterine cancers were clearly unrelated to radium exposure. Other cancers of the digestive tract appeared to be indirectly, if at all, associated with work in radium facilities. Lung cancer requires further investigation; inhalation exposures of the dial workers were reviewed. Analyses of the breast cancer data uncovered several observations inconsistent with the previously suggested causal association with radium exposure. Multiple myeloma was also reviewed. A threefold excess risk of death due to multiple myeloma has occurred, but is more closely correlated with duration of employment (a surrogate for external gamma radiation) than with radium intake

  17. Radiotherapy for the primary ocular adnexal lymphoma

    International Nuclear Information System (INIS)

    Objective: To study the pathological and clinical characteristics of primary lymphoma of ocular adnexae, analyze the treatment results and discuss the methods to prevent radiation complications. Methods: From Feb. 1995 to Feb. 2004, 25 patients with primary ocular adnexal lymphoma were treated in the second hospital and the forth hospital of Xuzhou, including 11 males and 14 females. The diagnosis was confirmed pathologically by biopsy in 19 patients and lumpectomy in 6 patients, including 22 mucosa-associated lymphoid tissue (MALT) lymphoma and 3 non-MALT lymphoma. According to the Ann Arbor Staging System, there were 21 patients with tumor in stage I E, 3 in stage II E and 1 in stage III E. The primary tumor was found in the eyelid or conjunctiva in 19 eyes and orbit in 9 eyes. Radiotherapy were given to 22 patients (25 eyes) by deep X-rays, 60Co γ-rays or mixed beams. The total irradiation dose ranged from 30.0 to 57.6 Gy. Kaplan-Meier method was used to calculate the survival rate and Logrank test was used to detect the difference between the different groups. Results: The 5-, 10-year accumulated survival rates (SR) of the whole group were 90% and 82%. The 10-year SR of patients with primary, eyelid or conjunctiva tumor and orbit tumor were 100% and 58% (P=0.032). The local control rates of the radiotherapy group and non-radiotherapy group were 92% and 33 % (P=0.006). The 10-year SR of patients with tumor completely removed and those with residues were 83% and 82% (P=0.907). The 10-year SR of MALT lymphoma and non-MALT lymphoma were 90.0% and 33.3% (P=0.009). After radiotherapy, 8 eyes (36%) had cataract formation and 7 eyes (28%) had xerophalmic symptoms. Conclusions: The results of radiothera- py for the primary ocular adnexal lymphoma are satisactory. The prognosis of patients with primary, eyelid or conjunctiva tumor is better than those with orbit tumor. The vast majority of the primary ocular adnexal lymphomas are MALT lymphomas. The survival rate of

    BRCA mutation carriers are at high risk of developing ovarian cancer. Ovarian malignancies are usually identified at an advanced stage with poor prognosis, attributed to inadequate options of early detection. Because of its risk-reducing effect of nearly 96%, prophylactic salpingo-oophorectomy is still the leading option for risk-reduction in women with a positive BRCA mutation status. The presence of ovarian cancer precursor lesions, such as epithelial inclusion cysts (EICs) or cortical invaginations (CIs), has previously been discussed in several studies with diverse conclusions. We retrospectively investigated a large and consistent population (n=94) of BRCA mutation carriers for the presence of potential preneoplastic and neoplastic changes. We also examined the role of specific lifestyle factors. Ninety-four women with disease-associated germline BRCA1 or BRCA2 mutations were included in this retrospective study. All women had undergone genetic counseling and prophylactic salpingo-oophorectomy, which was performed at a mean age of 43.33 years (range 27-66). Histological slides of both ovaries were reviewed by an independent pathologist. Data concerning lifestyle factors were collected from medical files and questionnaires. Two malignant lesions (2.1%), one bilateral serous papillary adenocarcinoma of the epithelial surface and one adenocarcinoma of the peritoneum with involvement of the left adnexa, and one lesion (1.1%) with obvious malignant potential, one mucinous borderline tumor of the right ovary, have been identified. We registered a high prevalence of CIs (30; 31.9%) and EICs (44; 46.8%) in prophylactically removed ovaries of BRCA mutation carriers. A significant correlation (P=0.002) was found with regard to the presence of EICs in women with increased BMI. Concerning the regular consumption of alcohol as a risk factor for premalignant lesions, in particular CIs, a statistically insignificant trend (P=0.083) was noted. Overweight women seem to be at

  19. Risk groups in pathologic stage III endometrial carcinoma

    International Nuclear Information System (INIS)

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

    Full Text Available BACKGROUND: Ovarian torsion presents as acute abdominal pain and early surgical management is required to prevent further adnexal damage. It accounts for 3% of all cases of acute abdominal pain in adult women. As signs and symptoms can mimic other acute abdominal conditions, the preoperative diagnosis often remains a challenge for primary care physicians. AIMS AND OBJECTIVES: To study the characteristics of adnexal torsion and factors influencing adnexal preservation. MATERIAL AND METHODS: All 14 patients were admitted in a tertiary endoscopic surgical unit with the complaints of pain in abdomen, nausea and vomiting of varying duration. The minimum duration of symptoms was 3 days and a maximum of 1 year. All patients were evaluated by ultrasound examination preoperatively. The time interval between the onset of symptoms and definitive surgery varied from 3 days to one year. Laparoscopic approach was offered to all patients except one where the patient was antenatal at 10 weeks of gestation. RESULTS: Out of 14 patients the youngest patient was a neonate 28 days old and oldest was 68 years of age. Most patients (n=9 were between 10 to 30 years of age. Intra operatively complete torsion (torsion of both ovary and fallopian tube was found in 9 cases, 3 were torsion of hydrosalpinx and one case was torsion of a paraovarian cyst. One case was torsion of the adnexa in antenatal period. Adnexal congestion and edema was the most common finding (n=6 simulating hemorrhagic cyst. One patient the oldest in series age 68 years had torsion of an ovarian mass which was histologically confirmed as mucinous cystadenoma. Two patients had ovarian dermoid where ovary was salvaged in one by doing cystectomy and in the other a salpingoophorectomy was performed. In one patient it was torsion of parovarian cyst where cyst wall excision was performed. In antenatal at 11 weeks gestation a mini laparotomy was performed under epidural analgesia and detorsion was performed

    OBJECTIVE Ovarian dysgerminoma is an uncommon ovarian malignancy. Its clinical features are special and there are many factors affecting its prognosis. If treated properly, the patient can be cured. Otherwise it may endanger the patient's life. The aim of this study is to investigate the clinical features and factors related to prognosis of ovarian dysgerminoma. METHODS Data from 57 patients with pure ovarian dysgerminoma were analyzed retrospectively. The patients were admitted to the Cancer Center, Sun Yat-sen University from January 1,1964 to December 31,2000. RESULTS The main clinical features were abdominal mass (56.1%), abdominal pain (21.1%), abdominal swelling (17.5%), vaginal bleeding (5.3%)and genital tract abnormalities (5.3%). Twenty-six patients had stage Ⅰ diseases,8 stage Ⅱ,9 stage Ⅲ,1 stage Ⅳ and 13 recurrent and persistent diseases. The uterus was involved in 41.2% of patients with stage Ⅱ-Ⅲ diseases. Combined modality was given to 52 cases and a singlemethod treatment to 5 cases. The total overall 5 and 10-year survival rates for stages Ⅰ-Ⅳ was 80.1% and 70.0% respectively. The 5-year survival rate for stage Ⅰ was 100%, stage Ⅱ 55.2% ,stage Ⅲ 55.6% and stage Ⅳ 0% ; for recurrent and persistent diseases, 72.7%. The stage I group of 12 patients received adnexectomy and 14 patients underwent hysterectomy and adnexa removal. There was no significant difference between the 5 and 10-year survival rates (all 100%). Of the 23 patients in the stage Ⅰ group to whomonly chemotherapy was given after operation, 19 cases received 3 or morecourses and were well without recurrence; 4 patients received only onecourse and one of them recurred 21 months after the operation. In the group of stages Ⅱ and Ⅲ cases, the 5-year survival rate was 86.7% for those whose chemotherapy courses were t> 4 and 25.0% for patients who received less than 4 courses of chemotherapy (P<0.05). CONCLUSIONS The prognosis of ovarian dysgerminoma is closely

  2. The cervical cap. An alternate barrier contraceptive method.

    The cervical cap is examined as an acceptable addition to barrier method technology. Attention is directed to its history, methodology, contradindications and side effects, effectiveness, and areas of current research. Invention of the modern cervical cap occurred in the mid-1800s. Finch reports that the 1st cervical cap was described in 1838 by Frederick Adolphe Wilde, a German gynecologist. He called it a Cautchuk Pessarium, and each cap was custom made from a wax impression of the woman's cervix. No matter who is credited with the invention of the cap, it remained a widely used method of contraception for the next century although principally employed in Europe. Currently, cervical caps are widely used in England and Central Europe. Use of the cap in the U.S. has been limited by the small amount of data on its demonstrated effectiveness as well as most clinican's belief that the method is too complicated for the "average woman." There are 2 primary types of cervical caps: firm and soft rubber. For the cap to be effective, it must be fitted by trained medical personnel. For maximum effectiveness, it is essential that the cervical cap user master the techniques of self insertion and removal. Most sources recommend that prior to insertion, the cap be approximately 1/3 filled with spermicidal cream or jelly. Whether or not a spermicide is used, the woman assumes a semi-reclining or squatting position. Removal of the cap is facilitated by inserting the index and middle fingers into the vagina and tiling the rim of the cap away from the cervix, thus breaking the suction. The cap can then be easily removed via the inserted fingers. The following conditions contraindicate the use of the cervical cap: cervical erosion or laceration; cervical malformation; Nabothian cysts; inflammation of the adnexa or inability of the woman to place and remove the cap correctly. The only reported side effect of the cap is the presence of a malodorous secretion if the cap is left in place

    Non-Hodgkin lymphoma of the orbit and ocular adnexa is the most common primary orbital malignancy. Treatments for low- (extra-nodal marginal zone and follicular lymphomas) and high-grade (diffuse large B-cell lymphoma) are associated with local and vision-threatening toxicities. High-grade lymphomas relapse frequently and exhibit poor survival rates. Despite advances in genomic profiling and precision medicine, orbital and ocular adnexal lymphomas remain poorly characterized molecularly. We performed targeted next-generation sequencing (NGS) profiling of 38 formalin-fixed, paraffin-embedded orbital and ocular adnexal lymphomas obtained from a single-center using a panel targeting near-term, clinically relevant genes. Potentially actionable mutations and copy number alterations were prioritized based on gain- and loss-of-function analyses, and catalogued, approved, and investigational therapies. Of 36 informative samples, including marginal zone lymphomas (n=20), follicular lymphomas (n=9), and diffuse large B-cell lymphomas (n=7), 53% harbored a prioritized alteration (median=1, range 0-5/sample). MYD88 was the most frequently altered gene in our cohort, with potentially clinically relevant hotspot gain-of-function mutations identified in 71% of diffuse large B-cell lymphomas and 25% of marginal zone lymphomas. Prioritized alterations in epigenetic modulators were common and included gain-of-function EZH2 and loss-of-function ARID1A mutations (14% of diffuse large B-cell lymphomas and 22% of follicular lymphomas contained alterations in each of these two genes). Single prioritized alterations were also identified in the histone methyltransferases KMT2B (follicular lymphoma) and KMT3B (diffuse large B-cell lymphoma). Loss-of-function mutations and copy number alterations in the tumor suppressors TP53 (diffuse large B-cell and follicular lymphoma), CDKN2A (diffuse large B-cell and marginal zone lymphoma), PTEN (diffuse large B-cell lymphoma), ATM (diffuse large B

The aim of this study was to test the efficacy of the Difoprev® system, consisting in a sock functioning as a vehicle for microcapsules containing moisturizing agents (Pseudoalteromonas ferment extract, a glycoprotein synthesized by the bacterium, Pseudoalteromonas antarctica NF3. The system is already widely used for cutaneous treatment in cases of neuropathic diabetic foot, and in prevention/treatment of dryness and hyperkeratosis of the skin of the lower extremities in elderly persons (shin/foot.Methodology: Sixteen patients aged >70 years (group A were treated with the Difoprev® system for 8 weeks. This group was compared with 8 patients of the same age (group B who wore the same type of sock without microcapsules. Following initial assessment at the time of recruitment, the patients underwent controls at 15, 30, and 60 days to assess the degree of hydration of the skin derived from an objective evaluation of degree of keratosis according to an arbitrary scale of seriousness ranging from 1 (absent to 4 (marked. The changes were rated according to a scale ranging from 1 (no improvement to 5 (marked improvement. A comparative study of all cases was conducted by means of photographs taken as the treatment commenced and on termination of treatment.Results: Most patients treated with Difoprev® presented a reduction in the degree of keratosis of the skin (90%, of whom 15% had marked improvement, compared to the patients who wore only the sock with no microcapsules (10% with slight improvement.

    International Nuclear Information System (INIS)

    Purpose: Mucosa-associated lymphoid tissue (MALT) lymphoma commonly presents in the gastrointestinal (GI) tract. Supradiaphragmatic MALT lymphoma is less common and its natural history is not well defined. This study was conducted to understand the natural history, to determine the frequency of synchronous disease in the GI tract, and to understand the patterns of disease progression after treatment for supradiaphragmatic MALT lymphoma. Patients and Methods: We retrospectively reviewed the medical records of 39 patients who presented with supradiaphragmatic MALT lymphoma between 1991 and 1997. Results: The median age of patients was 58 years (range, 25-90 years) with 16 male and 23 female patients. The most common primary site was salivary gland followed by ocular adnexa, lung, oral cavity, and others. Sixteen patients underwent esophagogastroduodenoscopy and biopsy (EGD + Bx) and 4 were found to have gastric involvement. Ann Arbor stages were the following: IEA, 17; IIEA, 5, IIEB, 1; and IVA, 16. The initial treatments were: involved field radiation therapy (n = 10), chemotherapy (n = 14), combination of radiation therapy and chemotherapy (n = 9), observation after biopsy (n = 4), antibiotics only (n = 1), and patient refusal of further intervention (n = 1). Seven patients received antibiotics as a part of the initial treatment. Every patient except for 1 was alive at a median follow-up of 39.5 months (range, 3-83 months). Thirty-six patients achieved complete response (CR) to the initial treatment. The actuarial 5-year progression-free survival rate was 83%. Progression of the disease occurred in 4 patients, with 2 in the stomach. Salvage attempts were made to 4 and were successful in 3. Of the 2 patients who relapsed in the stomach, 1 had negative EGD + Bx at the time of initial diagnosis. An EGD + Bx was not done in the second patient. Conclusion: Supradiaphragmatic MALT lymphoma appears to have a favorable prognosis. However, routine evaluation of the stomach

  7. The Clinical and Ultrasonic Study of Clinically Suspected Ectopic Pregnancy: Laying Emphasis on 15 proven Ectopic Pregnancies

    International Nuclear Information System (INIS)

    Ectopic preganacies are unsuccessful pregnancies that result from implantation of fertilized ovum occurring in an aberrant area. Aside from an emergency case, the early diagnosis of ectopic pregnancy is very difficult particularly in a case with insidious onset and mild clinical manifestations. Early diagnosis not only reduces the danger, but also simplifies the management of ectopic pregnancy. Ultrasonography has been an indispensable diagnostic tool in Obstetrics and Gynecology. In the authors' experience, clinical suspected ectopic pregnancy was one of the common indications for performing ultrasonography. Since Kobayashi at al. reported the appearances of ectopic pregnancy utilizing bistable B-scan ultrasonography, the ultrasonic findings of ectopic pregnancy have been reported by many authors. But, its accuracy and reliability in the diagnosis of ectopic pregnancy are still open to controversy. The authors studied 65 cases of clinically suspected ectopic pregnancy with Picker 80 L gray scale ultrasonography from Aug. 1982 to June. 1983. There were 29 confirmed cases, of which 15 were proved to have ectopic pregnancy and 14 were proved to have diseases other than ectopic pregnancy by surgical and histopathological study or by laparoscopy and follow up study. 29 confirmed cases were reviewed. The results were as follows: 1. Among 15 ectopic pregnancies, there were 12 ampullary pregnancies, 2 isthmic pregnancies and 1 interstitial pregnancy. Among 14 cases of no ectopic pregnancy, there were 5 intrauterine pregnancies, 3 myoma uteri, 2 P.I.D., and 1 case of dermoid cyst, cystic teratoma, H-mole and tubal hematoma due to previous tuball ligation, respectively. 2. The age distribution of ectopic pregnancy was from 22 to 41 years. The common clinical manifestations of ectopic pregnancy were lower abdominal pain (73.3%), vaginal spotting or bleeding (73.3%) and amenorrhea (66.7%). 3. Positive result of urine immunologic pregnancy test was 28.6% in ectopic pregnancy

Methods The mice were intraperitoneally injected with beta-estradiol 17 valerate which was suspended in sesame oil and then inoculated with different doses of P. bivia strains at the logarithmic phase. Samples of vaginal flushing fluid were collected at different time points after inoculation and used for the isolation of P. bivia strains and the detection of sialidase activities. Altogether 30 mice treated with estrogen and high dose of P. bivia were killed on days 2, 7 and 21 (n=10). Samples of cornua uteri, bladder and kidney were collected from those mice for P. bivia strains isolation. Re-sults Injection the estrogen-treated mice with P. bivia via vagina could cause the P. bivia infection for more than 14 days. The numbers of P. bivia strains isolated on day 21 decreased significantly. Enhanced sialidase activities and clue cells were observed in vaginal secretions of mice with P. bivia infection. Injection of mice with the high dose of P. bivia could spread the infection to cornua uteri. Conclusion Estrogen-treated mice could be

    The incidence of human papillomavirus (HPV) associated oropharyngeal squamous cell cancer (OSCC) is on the rise. With the HPV-positive uterine cervix as a reservoir, HPV-positive OSCC is discussed as a sexually transmitted disease. Mechanisms of HPV transmission to the oral cavity are poorly understood. To gain more insight into HPV-transmission routes, cervically HPV-positive women and their sexual partners are screened for oral HPV infection. Women with cervical dysplasia underwent HPV testing of the uterine cervix and tonsillar region via brush test. In addition, sexual partners received oral HPV testing. Tonsillar brush tests of patients admitted for routine surgery served as the control group. The HPV-PCR (Roche Linear Array Kit) was used to differentiate 37 HPV types. All participants completed a risk-factor questionnaire focusing on sexual habits. 101 women were tested HPV-positive at the cervix. Only 3/101 (3 %) were tested HPV-positive in the oropharynx. In 60/101 (60 %) women the sexual partner could be tested for oral HPV infection: testing was positive in 3/60 (5 %). No oral HPV was detected in the control group. The risk-factor questionnaire revealed significant differences between the female study- and control group in terms of age at first sexual intercourse and smoking habits. The limited data suggest that among sexual partners in Germany, HPV transmission to the oropharynx by oral-genital sex or by autoinoculation is a rare and unlikely event with low HPV concordance. Another explanation for the low oral prevalence could be an independent clearance of HPV from the oropharyngeal site compared to cervix uteri or at different time intervals. PMID:26961518

    Endosurgical correction of the uterus was carried out in 57 patients. Indications for surgery were improper positions of the uterus-retroversio, retrodeviatio uteri, excessive mobility of the uterus, and complaints of heaviness at the bottom of the abdomen, leukorrhea, pain of different type in the lower portions of the abdomen, profuse and long menses, dyspareunic pain upon deep penetration, reduced libido, a sensation of a foreign body in the vaginal cleft, urine incontinence upon strain. The mean age of the patients was 35 +/- 3 years. The disease duration varied from 1 to 8-9 years. In 9 women endosurgical correction of the uterus was combined with other interventions on the pelvic organs: colpoperine-orrhaphy with levator plasty was carried out in 5, laparoscopic myomectomy in 2, and dissection of intraperitoneal adhesions in 2 patients. In addition, surgical sterilization was carried out in 54 patients. After surgery the patients were administered only nonnarcotic analgetics. All the patients were discharged on days 2-3, those subjected to combined treatment on days 8-9. The patients were followed up for up to 2 years. The general and psychoemotional status of the majority of patients improved, and the incidence of such symptoms as leukorrhea, pain at the bottom of the abdomen, profuse and long menses was 4, 6, and 5 times reduced, respectively. Endosurgical correction of the uterus in women of a reproductive age should be a method of choice; it can be carried out separately or in combination with plasty of the vaginal walls. PMID:8779353

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

    Melanoma is one of the most aggressive human malignant tumors. Its incidence and mortality are growing steadily. Ultraviolet irradiation is the main risk factor for melanoma involved in melanomagenesis. The probability of viral etiology of melanoma has been discussed. Human papillomaviruses (HPV) have been mentioned among candidates for its etiologic agents because some HPV types are the powerful carcinogens causing cervical cancer and other cancers. The review analyses the literature data on the association of melanoma with HPV Several groupsfound HPVin skin melanomas as well as in mucosa; viruses of high oncogenic risk were detected in some cases. For some organs the etiological role of high-risk HPV as inducers of invasive carcinomas is confirmed. These organs require special mention: cervix uteri, vulva, vagina, penis, anal region, and oral cavity. However in the majority of the studies in which viral DNA-positive melanomas were found, testing for viral genome expression was not done while this is the fact of primary importance. HPVare found in normal skin and mucous membranes thus creating justifiable threat of tumor specimen contamination with viral DNA in vivo. There are limited data on aggravation of the disease prognosis in papillomavirus-positive melanomas. However, any systematic observation of a sizeable patient group distinguished by that tumor type has not been performed yet. Viral E6 and E7 oncogenes of high-risk papillomaviruses were shown to be able to transform normal human melanocytes in vitro experiments. Thus, we can assume the presence of the association of melanoma with oncogenic HPV. The clinical significance of this problem is indisputable under the conditions of the steady increase in melanoma incidence and mortality rates in Russia and abroad. The problem requires further study. PMID:27522713

    Objective: To examine the potential of pre-gestational intake of Laportea interrupta L. (L. interrupta) leaf decoction as an aid for fetal-maternal health by determining its influence on embryonic implantation and growth, placental labyrinth vasculo-angiogenesis, and junctional zone morphology. Methods: Eight-week-old female mice were divided into groups and fed daily with 3.5 g food/mouse. The control was given drinking water, the treatment groups, low (LC), medium (MC), and high (HC) concentrations, were given 25%, 50%, and 100% v/v stock solution, respectively for 14 days, prior to mating. Pregnant mice were sacrificed at 14.5 days post-coitus. The uteri and placentae were collected and weighed; implantation sites were counted as either viable or resorbing. The estimated weight (g)/ embryo, as a function of the number of implantation sites, was evaluated. The histology of placental labyrinth angiogenesis and junctional zone morphology was examined. Results: The viable site ratios increased as leaf decoction concentration increased. This was most significant in the HC group (P<0.05). The HC group exhibited increase in the estimated embryo weight and implantation sites, and placental labyrinth with very prominent blood vessels. There was lesser depletion of junctional zone in all treatment groups with large blood vessels and glycogen cells that were more apparent in MC and HC group than those of the control and LC groups. Conclusion: Pre-gestational consumption of L. interrupta leaf decoction in high concentrations demonstrated its potential to support fetal-maternal health.

  17. CRISPLD2 is a target of progesterone receptor and its expression is decreased in women with endometriosis.

    Full Text Available Endometriosis, defined as the presence of endometrial cells outside of the uterine cavity, is a major cause of infertility and pelvic pain, afflicting more than 10% of reproductive age women. Endometriosis is a chronic inflammatory disease and lipopolysaccharide promotes the proliferation and invasion of endometriotic stromal cells. Cysteine-rich secretory protein LCCL domain-containing 2 (CRISPLD2 has high affinity for lipopolysaccharide and plays a critical role in defense against endotoxin shock. However, the function of CRISPLD2 has not been studied in endometriosis and uterine biology. Herein, we examined the expression of CRISPLD2 in endometrium from patients with and without endometriosis using immunohistochemistry. The expression of CRISPLD2 was higher in the secretory phase in human menstrual cycle compared to proliferative phase. The expression of CRISPLD2 was significantly decreased in the endometrium of women with endometriosis in the early secretory phase compared to women without endometriosis. The increase of CRISPLD2 expression at the early secretory and dysregulation of its expression in endometriosis suggest progesterone (P4 regulation of CRISPLD2. To investigate whether CRISPLD2 is regulated by P4, we examined the expression of the CRISPLD2 in the uteri of wild-type and progesterone receptor knock out (PRKO mice. The expression of CRISPLD2 was significantly increased after P4 treatment in the wild-type mice. However, CRISPLD2 expression was significantly decreased in the (PRKO mice treated with P4. During early pregnancy, the expression of CRISPLD2 was increased in decidua of implantation and post-implantation stages. CRISPLD2 levels were also increased in cultured human endometrial stromal cells during in vitro decidualization. These results suggest that the CRISPLD2 is a target of the progesterone receptor and may play an important role in pathogenesis of endometriosis.

    Full Text Available Abstract Background Adenomyosis is a common gynecological disease, which is accompanied by a series of immunological and neuroendocrinological changes. Nerve growth factor (NGF plays a critical role in producing pain, neural plasticity, immunocyte aggregation and release of inflammatory factors. This study aimed to investigate the expression of NGF and its two receptors in uteri and dorsal root ganglia (DRG in an adenomyosis mouse model, as well as their relationship with the severity of adenomyosis. Methods Forty newborn ICR mice were randomly divided into the adenomyosis model group and control group (n = 20 in each group. Mice in the adenomyosis model group were orally dosed with 2.7 μmol/kg tamoxifen on days 2-5 after birth. Experiments were conducted to identify the expression of NGF- beta and its receptors, tyrosine kinase receptor (trkA and p75 neurotrophin receptor (p75NTR, in the uterus and DRG in four age groups (90+/-5 d, 140+/-5 d, 190+/-5 d and 240+/-5 d; n = 5 mice in each group by western bolt, immunochemistry and real time reverse transcription-polymerase chain reaction. Results Adenomyosis, which became more serious as age increased, was successfully induced in dosed ICR mice. NGF-beta, trkA and p75NTR protein levels in the uterus and trkA mRNA levels in DRG were higher in the older aged adenomyosis model group than those in controls (190+/-5 d and 240+/-5 d groups, P Conclusions NGF- beta can be used as an indicator for the severity of adenomyosis. The gradually increasing level of NGF- beta and its receptors while the disease becomes more severe suggests an effect of NGF- beta on pathogenic mechanisms of adenomyosis.

    Adenomyosis is defined by the presence of endometrial glands and stroma within the myometrium. Despite its frequent occurrence, the precise aetiology and physiopathology of adenomyosis is still unknown. WNT/β-catenin signalling molecules are important and should be tightly regulated for uterine function. To investigate the role of β-catenin signalling in adenomyosis, the expression of β-catenin was examined. Nuclear and cytoplasmic β-catenin expression was significantly higher in epithelial cells of human adenomyosis compared to control endometrium. To determine whether constitutive activation of β-catenin in the murine uterus leads to development of adenomyosis, mice that expressed a dominant stabilized β-catenin in the uterus were used by crossing PR-Cre mice with Ctnnb1(f(ex3)/+) mice. Uteri of PR(cre) (/+) Ctnnb1(f(ex3)/+) mice displayed an abnormal irregular structure and highly active proliferation in the myometrium, and subsequently developed adenomyosis. Interestingly, the expression of E-cadherin was repressed in epithelial cells of PR(cre) (/+) Ctnnb1(f(ex3)/+) mice compared to control mice. Repression of E-cadherin is one of the hallmarks of epithelial-mesenchymal transition (EMT). The expression of SNAIL and ZEB1 was observed in some epithelial cells of the uterus in PR(cre) (/+) Ctnnb1(f(ex3)/+) mice but not in control mice. Vimentin and COUP-TFII, mesenchymal cell markers, were expressed in some epithelial cells of PR(cre) (/+) Ctnnb1(f(ex3)/+) mice. In human adenomyosis, the expression of E-cadherin was decreased in epithelial cells compared to control endometrium, while CD10, an endometrial stromal marker, was expressed in some epithelial cells of human adenomyosis. These results suggest that abnormal activation of β-catenin contributes to adenomyosis development through the induction of EMT. PMID:23784889

    Background and purpose. Many observations on potential inadequate coverage of tumour volume at risk in advanced cervical cancer (CC) when conventional radiation fields are used, have further substantiated by investigators using MRI, CT or lymph-angiographic imaging. This work tries to obtain three dimensional margins by observing enlarged nodes in CT scans in order to improve pelvic nodal chains clinical target volumes (CTVs) drawing, and by looking for corroborative evidence in the literature for a better delineation of tumour CTV. Method. Eleven consecutive patients (seven males, four females, mean age 62 years, range 43 8) with CT diagnosis of nodal involvement caused by pathologically proved carcinoma of the cervix (n = 2), carcinoma of the rectum (n = 2), carcinoma of the prostate (n = 2), non-Hodgkin lymphoma (n 2), Hodgkin lymphoma (n = 1), carcinoma of the penis (n = 1) and carcinoma of the corpus uteri (n = 1) were retrospectively reviewed. Sixty CT scans with 67 enlarged pelvic nodes were reviewed in order to record the more proximal structures (muscle, bone, vessels, cutis or sub-cutis and other organs) to each enlarged node or group of nodes according to the four surfaces (anterior, lateral, posterior and medial) in a clockwise direction. Results. summary of the observations of each nodal chain and the number of occurrences of every marginal structure on axial CT slices is presented. Finally, simple guidelines are proposed. Conclusions. Tumour CTV should be based on individual tumour anatomy mainly for lateral beams as it results from sagittal T2 weighted MRI images. Boundaries of pelvic nodes CTVs can be derived from observations of enlarged lymph nodes in CT scans. (author)

  1. MR imaging findings in cesarean scar pregnancy

    International Nuclear Information System (INIS)

    Objective: To analyze MRI findings of cesarean scar pregnancy (CSP). Methods: The MR findings in 18 patients who were diagnosed as CSP by surgery from March 2010 to November 2011 were retrospectively analyzed, and comparison was made between the MRI findings and surgical results. Results: All Gestational sacs (18) were clearly detected by MRI. Among the 18 cases,gestational sac presented as cystic mass with smooth margin located within the scar of uterine wall at the lower anterior uterus in 16 cases. In 2 of the 16 cases, gestational sac was found within the myometrium, whereas in the remaining 14 cases, gestational sac was found partially within the myometrium with extension into the uterine cavity. The anterior wall of isthmus uteri became thinner. In the remaining 2 of the 18 cases, gestational sac presented as irregular, multilobolated mass, growing deep into the myometrium as well as into the uterine cavity. On T2WI, the mass showed heterogeneous signal intensity. A small amount of hemorrhage within the mass and uterine cavity could be seen on T1WI. An enhancing solid component with a heterogeneous mass could be seen. All gestational sacs in 18 cases were located at or adjacent to the previous cesarean scar. In the area of cesarean scar,the signal of the uterine wall was disconnected, with focal indentation or thinning and the previous cesarean scar exhibited hypointensity on both T1WI and T2WI. Conclusion: CSP has its unique findings on MRI, these specific features can provide useful information in the management of CSP. (authors)

  2. Clinical trial of carbon ion radiotherapy for gynecological melanoma

    International Nuclear Information System (INIS)

    Carbon ion radiotherapy (C-ion RT) is an advanced modality for treating malignant melanoma. After we treated our first case of gynecological melanoma using C-ion RT in November 2004, we decided to conduct a clinical trial to evaluate its usefulness for the treatment of gynecological melanoma. The eligibility criteria for enrollment in this study were histologically proven malignant melanoma of the gynecological regions with lymph node metastasis remaining in the inguinal and pelvic regions. The small pelvic space, including the GTV and the metastatic lymph node, was irradiated with up to a total dose of 36 GyE followed by a GTV boost of up to a total dose of 57.6 GyE or 64 GyE in 16 fractions. A series of 23 patients were treated between November 2004 and October 2012. Patient age ranged from 51-80 with a median of 71. Of the tumor sites, 14 were located in the vagina, 6 in the vulva, and 3 in the cervix uteri. Of the 23 patients, 22 were irradiated with up to a total dose of 57.6 GyE, and 1 patient was irradiated with up to a total dose of 64 GyE. Chemotherapy and interferon-β were also used to treat 11 of the patients. Acute and late toxicities of Grade 3 or higher were observed in 1 patient treated with concurrent interferon-β. The median follow-up time was 17 months (range, 6-53 months). There was recurrence in 14 patients, and the 3-year local control and overall survival rates were 49.9% and 53.0%, respectively. C-ion RT may become a non-invasive treatment option for gynecological melanoma. (author)

    Purpose This study was conducted to investigate the incidence and survival outcomes of second primary cancers after the diagnosis of cervical cancer. Materials and Methods Data from the Korea Central Cancer Registry between 1993 and 2010 were reviewed and analyzed. Standardized incidence ratios (SIRs) of second primary cancers among women with cervical cancer were analyzed. Kaplan-Meier survival curves were constructed for cervical cancer patients with or without a second primary cancer. Results Among 72,805 women with cervical cancer, 2,678 (3.68%) developed a second primary cancer within a mean follow-up period of 7.34 years. The overall SIR for a second cancer was 1.08 (95% confidence interval, 1.04 to 1.12). The most frequent sites of second primary cancers were the vagina, bone and joints, vulva, anus, bladder, lung and bronchus, corpus uteri, and esophagus. However, the incidence rates of four second primary cancers (breast, rectum, liver, and brain) were decreased. The 5-year and 10-year overall survival rates were 78.3% and 72.7% in all women with cervical cancer, and for women with a second primary cancer, these rates were 83.2% and 65.5% from the onset of cervical cancer and 54.9% and 46.7% from the onset of the second primary cancer, respectively. Conclusion The incidence rates of second primary cancers were increased in women with cervical cancer compared to the general population, with the exception of four decreasing cancers. The 10-year overall survival rates were decreased in cervical cancer patients with a second primary cancer. PMID:26194366

    Dirofilaria scapiceps was found between the synovial sheath and tendons, i.e., within the tendon sheath, in the ankle region of eastern cottontail rabbits (Sylvilagus floridanus) and snowshoe hares (Lepus americanus). In cottontail rabbits, tendons and sheaths appeared normal and all worms were adults. Only one (4%) of 24 infected rabbits contained dead worms. All female worms were gravid in rabbits killed in late winter or early spring. Microfilaremias in rabbits were high (approximately 30-100 microfilariae/60 microliter blood) and of long duration (at least 8-28 mo), and rabbits were considered normal hosts of D. scapiceps. In some snowshoe hares, tendons and sheaths also appeared normal; however, in other hares a chronic proliferative tenosynovitis, characterized by fibrinous exudate, hyperplasia and hypertrophy of the intima and inflammatory cell (predominantly lymphocytes and plasma cells) infiltration of the intimal and fibrous layers of the synovial sheath led to encapsulation of worms. Dead subadult, dead adult, and live adult worms were found in the ankles of hares; 86 (46%) of 186 infected hares contained some or only dead worms. Fibrosis commonly occurred around dead worms. Dead subadults were also found in subcutaneous connective tissues over the trunk of the body. Degenerate embryos and amorphous material were observed in uteri of some female worms in hares killed in late winter or early spring. Few (1-5 microfilariae/60 microliter blood) or no microfilariae were observed in the peripheral blood of hares and microfilaremias were of short duration (less than 8 mo). Microfilariae in hares are probably trapped and destroyed in the chronic inflammatory lesions in the tendon sheaths since normal, degenerate, and calcified microfilariae were observed in the capsules around adult worms. Some microfilariae might also be destroyed in lymph nodes. Although D. scapiceps can be maintained within snowshoe hare populations, hares are considered abnormal hosts of D

    Purpose: To evaluate the association between magnetic resonance imaging (MRI) derived uterine and leiomyoma characteristics and symptoms demanding treatment. Materials and methods: Consecutive patients (n = 122; mean age, 47.5 years) with symptomatic leiomyomas participated in a prospective study. The leiomyoma/endometrium relationship, sizes of leiomyomas and uteri, and number and enhancement of leiomyomas were determined by MRI. Submucosal leiomyomas were classified as protruding either {>=}50% or <50% into the uterine cavity. Results: Sixty-nine patients (57%) had menorrhagia and pressure symptoms, while 26 (21%) had only menorrhagia and 27 (22%) pressure symptoms alone. Leiomyomas with {>=}50% protrusion into the uterine cavity were detected more often in patients with both symptoms or just menorrhagia than in those with pressure symptoms only (18/69 [26%] versus 1/27 [4%], P = 0.013; 10/26 [39%] versus 1/27 [4%], P = 0.002, respectively). The degree of enhancement of leiomyomas was higher (P = 0.005) and leiomyomas were smaller (P = 0.002) in patients with menorrhagia than in those with pressure symptoms. Large uterine and leiomyoma measures were associated with increased urinary frequency (P values 0.002-0.032). Urinary stress incontinence, abdominal pain, and pressure on the back were not associated with MRI findings. Conclusion: In comparison with pressure symptoms, menorrhagia is associated with smaller uterine and leiomyoma size and with more intense enhancement. While a submucosal leiomyoma largely protruding into the cavity contributes to menorrhagia, significance of a minor submucosal component seems to be unclear. The large leiomyoma and uterine volumes contribute to increased urinary frequency, whereas other mechanisms for urinary stress incontinence and pain symptoms should be considered.

    Two trials were conducted in which Angus x Hereford first-calf cows were assigned randomly at calving to one of two treatments: exposure to mature penile-blocked bulls (BE) or isolation from bulls (NE). In Trial 1 (BE, n = 38; NE, n = 37), cow to bull ratio increased from 12:1 to 19:1 over a 14-d period; in Trial 2 (BE, n = 25; NE, n = 24), this ratio was maintained at 13:1. In both trials, blood samples were collected weekly for progesterone and ovaries and uteri of cows were examined rectally. Cows were observed for estrus twice daily (am:pm) beginning 10 d after calving. In Trial 2, intensive blood sampling for LH began 10 d after calving (eight cows per treatment) and continued at weekly intervals until estrus or the end of the trial. Postpartum weight change, condition score change and time to uterine involution did not differ (P greater than .10) between treatments in either trial. Interval to estrus was shorter (P less than .05) for BE cows than for NE cows in both trials. A greater proportion (P less than .05) of BE cows exhibited estrus by 60 and 90 d after calving and showed an increase in progesterone before first estrus. Mean and baseline LH concentrations and amplitude, frequency and duration of LH pulses were not altered (P greater than .10) by bull exposure. In conclusion, exposing first-calf suckled beef cows to bulls after calving hastened resumption of estrous cycles. Bull exposure did not alter patterns of LH concentrations but did increase proportions of cows that showed increased progesterone before first estrus. PMID:2365649

    Full Text Available Abstract Background Nomegestrol acetate (NOMAC, a synthetic progestogen derived from 19-nor-progesterone, recently completed clinical trials for use with 17beta-estradiol in a new monophasic combined oral contraceptive. In this review, published as well as previously unpublished preclinical studies that detail the effects of NOMAC on estrogenic, progestogenic, and androgenic systems, as well as mineralocorticoid, glucocorticoid, bone, and metabolic indices are described. Methods In vitro assays to determine NOMAC structure-activity relationships used tissue derived from rat uteri. Transactivation profiles were performed using Chinese hamster ovary (CHO cells transfected with cDNAs encoding human steroid receptors. Estrogenic and anti-estrogenic activities were monitored in vivo in rats as well as in vitro in human breast cancer cells. Standard in vivo techniques were used in rats to determine progestational activity; antigonadotropic, androgenic, mineralocorticoid, and glucocorticoid activities; as well as effects on bone and other metabolic indices. Ovulation inhibition was monitored in rats and primates. NOMAC’s effects on cardiovascular systems were determined in dogs and primates. Results NOMAC was without significant agonistic or antagonistic activity for estrogen receptor alpha or beta in vitro, and inhibited ovulation in rats and monkeys (2.5 mg/kg and 1 mg/kg, respectively. NOMAC lacked androgenic, antimineralocorticoid, glucocorticoid, and metabolic activity and exhibited moderate anti-androgenic activity in rats. NOMAC did not affect bone mineral density (BMD in rats or hemodynamic and electrophysiologic parameters in dogs and primates. Conclusions NOMAC is a selective progestogen structurally similar to progesterone that has modest anti-androgenic activity and does not affect lipid or carbohydrate metabolism, BMD, or many cardiovascular parameters in selected animal models.

    Of the 2,635,000 new cancer cases (excluding non-melanoma skin cancers) occurring in the European Union (EU) in 2012, it is estimated that approximately 185,000 are related to infection with human papillomaviruses (HPVs), hepatitis B and C viruses (HBV and HCV), and Helicobacter pylori (H. pylori). Chronic infection with these agents can lead to cancers of the cervix uteri, liver, and stomach, respectively. Chronic infection with HCV can also lead to B-cell non-Hodgkin lymphoma. Human immunodeficiency virus (HIV) infection continues to be of major public health importance in several EU countries and increases cancer risk via HIV-induced immunosuppression. The fourth edition of the European Code Against Cancer presents recommendations on effective and safe preventive interventions in order to reduce the risk of infection-related cancers in EU citizens. Based on current available evidence, the fourth edition recommends that parents ensure the participation of their children in vaccination programs against HBV (for newborns) and HPV (for girls). In the 'Questions and Answers' (Q&As) section about vaccination and infections in the website for the European Code Against Cancer, individuals who are at risk of chronic HBV or HCV are advised to seek medical advice about testing and obtaining treatment when appropriate. Individuals most at risk of HIV are advised to consult their doctor or healthcare provider to access counselling and, if needed, testing and treatment without delay. Information about H. pylori testing and treatment is also provided as testing might currently be offered in some high-risk areas in Europe. The rationale and supporting evidence for the recommendations on vaccination in the European Code Against Cancer, and for the main recommendations on vaccination and infection in the Q&As, are explained in the present review.

    Women with endometriosis can suffer from decreased fecundity or complete infertility via abnormal oocyte function or impaired placental-uterine interactions required for normal pregnancy establishment and maintenance. Although AT-rich interactive domain 1A (SWI-like) (ARID1A) is a putative tumor suppressor in human endometrial cancers and endometriosis-associated ovarian cancers, little is known about its role in normal uterine function. To study the potential function of ARID1A in the female reproductive tract, we generated mice with a conditional knockout of Arid1a using anti-Müllerian hormone receptor 2-Cre Female Arid1a conditional knockout mice exhibited a progressive decrease in number of pups per litter, with a precipitous decline after the second litter. We observed no tumors in virgin mice, although one knockout mouse developed a uterine tumor after pregnancy. Unstimulated virgin female knockout mice showed normal oviductal, ovarian, and uterine histology. Uteri of Arid1a knockout mice showed a normal decidualization response and appropriate responses to estradiol and progesterone stimulation. In vitro studies using primary cultures of human endometrial stromal fibroblasts revealed that small interfering RNA knockdown of ARID1A did not affect decidualization in vitro. Timed pregnancy studies revealed the significant resorption of embryos at Embryonic Day 16.5 in knockout mice in the third pregnancy. In addition to evidence of implantation site hemorrhage, pregnant Arid1a knockout mice showed abnormal placental morphology. These results suggest that Arid1a supports successful pregnancy through its role in placental function. PMID:26962117

    Tobacco use is a well-established risk factor for many types of cancers. Recent data on selected cancer incidence and mortality related to smoking in the Indonesian population are provided in this study. Morbidity and mortality data were derived from GLOBOCAN 2012 and the population attributable fraction (PAF) was estimated using the standard methodology developed by the World Health Organization. Using these data, we calculated disability adjusted life year (DALY) values for smoking-related cancer. The DALY was estimated by summation of the years lived with disability (YLD) and years life lost due to premature death (YLL). The cancer cases related to smoking in Indonesia numbered 45,132, accounting for 35,580 cancer deaths. The morbidity and mortality of lung cancer can be considered as the highest priority in both men and women. Furthermore the greatest YLD due to smoking in Indonesian men and women were from pancreas and lung cancers. For YLL among men, the highest years lost were from lung and liver cancers. On the other hand, among women lung oral cavity and lip were most important. Based on the DALY indicator, burden priorities for Indonesian men were lung cancer (298,980), liver cancer (60,367), and nasopharynx (46,185), while among Indonesian women they were lung cancer (34,119), cervix uteri (9,213) and pancreas cancer (5,433). In total, Indonesian burden of cancers attributed to smoking was 638,682 DALY. This study provides evidence about the burden of cancers caused by smoking as a rational basis for initiating national tobacco control policies in Indonesia. PMID:27039808

  11. A Pilot Study of Uterine Artery Embolization with Tris-Acryl Gelatin Microspheres in Guinea Pigs

    International Nuclear Information System (INIS)

    Objective: This study was designed to establish guinea pigs as an animal model for uterine artery embolization (UAE) with tris-acryl gelatin microspheres (TAGM). Methods: Twenty-five female adult guinea pigs were randomly divided into two groups, including a uterine artery casting mould group (n = 10) and a UAE group (n = 15). Pelvic angiography and vascular casting mould were performed in the first group. The anatomical characters of the pelvic cavity in guinea pigs were described. In the second group, the technical feasibility of performing UAE with TAGM in guinea pigs was investigated. The histopathological slides of the uterus of guinea pigs after UAE were examined to inspect the outcomes of UAE. Results: The uterine artery springs from the internal iliac artery, ascends tortuously along the cervix, and gives off vertically 8–10 branches to the cervix uteri and uterine horns. The diameters of the trunk of the uterine artery and its first branch were 0.32 ± 0.027 mm and 0.14 ± 0.01 mm, respectively. For UAE animals, the dosages of 40–120 and 100–300 μm TAGM were 0.033 ± 0.003 ml and 0.015 ± 0.002 ml, respectively. On histopathological slides, embosphere particles were found in the first branches of the uterine artery, the subserous arteries, and the intramural arteries. Inflammatory reactions in the uterus were common in guinea pigs after UAE. Local or dispersed areas of necrosis in uterus also were observed in a few guinea pigs. Conclusions: Guinea pigs are an appropriate and feasible model for UAE with TAGM.

  12. Reproductive biology of Onchocerca ochengi, a nodule forming filarial nematode in zebu cattle.

    Onchocerca ochengi is a nodule-forming filarial nematode parasite of cattle in tropical Africa and closely related to the human pathogen Onchocerca volvulus. The adult worms reside in intradermal nodules. While females are sedentary, males may move between nodules. The first stage larvae (microfilariae) disperse in the skin of the host waiting to be taken up by the intermediate host. The density of microfilariae in the skin is largely independent of the number of adult worms present indicating some form of density dependent control. Recently, Onchocerca sp. Siisa, a form of Onchocerca distinguishable from O. ochengi by mitochondrial DNA sequences but not by morphology, was described to occur in cattle. This raised the question if Onchocerca sp. Siisa represents a different mitochondrial clade of O. ochengi or a new species. In order to study the reproductive biology and to understand this self-control of the off-spring population we systematically analyzed all Onchocerca nodules from the skin of one zebu cow and we examined a sample of microfilariae from a skin biopsy. We identified 87 O. ochengi females and 146 males. 56 (64.4%) of the females contained developing embryos. In order to assign the progeny to their respective parents we determined the genotypes at six nuclear and two mitochondrial molecular genetic markers in the adult worms, in a fraction of the progeny present in the uteri of the females and in the skin microfilariae. The 121 skin microfilariae we analyzed originated from at least 17 different mothers, which contributed rather differently to the total. Forty-five larvae (37.2%) were the progeny of a single female. Of the adult worms 16.7% were of the type Onchocerca sp. Siisa. These worms appeared to interbreed freely with the rest of the O. ochengi population and therefore belong to the same species.

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

    International Nuclear Information System (INIS)

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

  14. Uterine dysfunction in biglycan and decorin deficient mice leads to dystocia during parturition.

    Directory of Open Access Journals (Sweden)

    Zhiping Wu

    Full Text Available Cesarean birth rates are rising. Uterine dysfunction, the exact mechanism of which is unknown, is a common indication for Cesarean delivery. Biglycan and decorin are two small leucine-rich proteoglycans expressed in the extracellular matrix of reproductive tissues and muscle. Mice deficient in biglycan display a mild muscular dystrophy, and, along with mice deficient in decorin, are models of Ehlers-Danlos Syndrome, a connective tissue anomaly associated with uterine rupture. As a variant of Ehlers-Danlos Syndrome is caused by a genetic mutation resulting in abnormal biglycan and decorin secretion, we hypothesized that biglycan and decorin play a role in uterine function. Thus, we assessed wild-type, biglycan, decorin and double knockout pregnancies for timing of birth and uterine function. Uteri were harvested at embryonic days 12, 15 and 18. Nonpregnant uterine samples of the same genotypes were assessed for tissue failure rate and spontaneous and oxytocin-induced contractility. We discovered that biglycan/decorin mixed double-knockout dams displayed dystocia, were at increased risk of delayed labor onset, and showed increased tissue failure in a predominantly decorin-dependent manner. In vitro spontaneous uterine contractile amplitude and oxytocin-induced contractile force were decreased in all biglycan and decorin knockout genotypes compared to wild-type. Notably, we found no significant compensation between biglycan and decorin using quantitative real time PCR or immunohistochemistry. We conclude that the biglycan/decorin mixed double knockout mouse is a model of dystocia and delayed labor onset. Moreover, decorin is necessary for uterine function in a dose-dependent manner, while biglycan exhibits partial compensatory mechanisms in vivo. Thus, this model is poised for use as a model for testing novel targets for preventive or therapeutic manipulation of uterine dysfunction.

    Decidualization is crucial for successful pregnancy in mice and humans. Although many essential molecular modulators have been identified during decidualization, the precise molecular mechanism of uterine decidualization remains largely unknown. Our previous research indicates that luman recruiting factor (LRF) is strongly expressed in decidual uteri of mice on days 6-8 of pregnancy. In this study, our aim is to determine the biological functions of LRF during decidualization in mice. We used the shLRF lentivirus to attenuate the expression of LRF, which significantly reduced the weight and size of implantation sites on days 7-8 of pregnancy. In a stromal cell culture model, LRF mRNA and protein levels increased significantly during stromal cell decidualization induced by estrogen and progesterone. LRF silencing resulted in the decidual markers decidual prolactin-related protein, insulin-like growth factor-binding protein 1 and progesterone receptor being dramatically reduced, and the decidual process was significantly inhibited. Cell-cycle analysis and cell apoptosis analysis revealed that, although no obvious apoptosis occurred in shLRF-lentivirus-infected stromal cells during decidualization, proliferation was inhibited via S-phase cell-cycle arrest, and the mitotic activity of uterine stromal cells was inhibited. An examination of cell-cycle regulatory factors indicated that the mRNA expression levels of cyclin A and cyclin B1 were significantly down-regulated after treatment with shLRF lentivirus. Thus, LRF seems to be involved in the regulation of decidualization during pregnancy by modulating the expression of the key cell-cycle regulatory factors cyclin A and cyclin B1. PMID:27053244

    In this study, endometrosis and angiosclerosis in mares were studied. Endometrosis is a severe, progressive, and irreversible fibrotic condition that affects the endometrium, whereas angiosclerosis refers to thickening of vessel walls due to degenerative changes leading to reduced elasticity of the walls and lower perfusion. Histologic evaluations were performed on biopsies and compared with vascular features of the endometrial surface obtained via narrow-band imaging (NBI) hysteroscopy. First, it was determined if hysteroscopic evaluation of the endometrium using NBI resulted in a better visualization of the vascular pattern (i.e., vessel-versus-background contrast was increased) compared with using white light. This was found to be the case for examinations in vivo (n = 10), but not when using abattoir uteri (n = 3). In the second part of this study, it was determined if vascular densities and sizes as derived from NBI images could be used as indicators for the degree of degenerative changes of the equine endometrium and its vessels. Narrow-band imaging hysteroscopic evaluations were performed (n = 10), and endometrial biopsies (n = 32) were collected. Histologic specimens were evaluated for degree of endometrosis and angiosclerosis, and they were classified in Kenney categories. Narrow-band imaging images were analyzed for vascular pattern. Samples classified to Kenney category I, or without signs of vessel degeneration, had significantly higher vascular densities than samples from Kenney category IIa or with angiosclerosis. In conclusion, narrow-band imaging facilitates enhanced visualization of the vasculature of the equine endometrium during hysteroscopies, which has applications in detection of endometrosis and angiosclerosis.

  17. CT manifestation of the carcinoma of ovary: diagnosis and differential diagnosis

    International Nuclear Information System (INIS)

    Objective: To study the CT manifestations of carcinoma of ovary and the CT findings that mimic the carcinoma of ovary. Methods: CT findings were retrospectively studied in 47 cases of pelvic masses including 42 cases of carcinoma of ovary and 5 misdiagnosed as carcinoma of ovary. Misdiagnosis was made in 8 of the 42 cases of carcinoma of ovary. Non-contrast and enhanced CT scan were performed in all cases. Results: Pelvic or abdominal-pelvic masses were demonstrated in 92.4% cases. The lesions were parenchymatous, cystic, or cystic-parenchymatous masses, in which the parenchyma and septum were remarkably enhanced after the contrast agent was given intravenously. No mass was found in 7.6% cases, in which the ascites and thickening of the omentum were noted on CT images. Ascites was shown in 57.2% cases. Calicification was manifested in 19.0% cases. Abscess or tuberculosis located in pelvis could have the similar CT findings with cystic carcinoma of ovary, while these infectious lesions presented with regular or smooth wall and septum, instead of mural nodule. Another characteristic sign of abscess or tuberculosis was air density identified within the cavity of the cysts. Chocolate cysts with recent hemorrhage or subserous leiomyoma uteri with cystic degeneration were cystic-parenchymatous mass during the non-contrast enhanced scan. No enhancement could be revealed in parenchyma of the former and slight enhancement could be identified in the parenchymatous component of the latter. Conclusion: Contrast enhanced CT scan can demonstrate the structure of the mass and the adjacent organs, and reveal the enhancement of the lesions, which plays a valuable role in diagnosis or differential diagnosis of carcinoma of ovary with atypical CT findings.

    Trypanosoma brucei gambiense, transmitted by the tsetse fly, is the main causative agent of Human African trypanosomosis in West Africa and poses a significant health risk to 70 million people. Disease progression varies depending on host immunity, but usually begins with a haemo-lymphatic phase, followed by parasite invasion of the central nervous system. In the current study, the tropism of T. b. gambiense 1135, causing a low level chronic 'silent' infection, was monitored in a murine model using bioluminescence imaging and PCR. A tropism to the reproductive organs, in addition to the central nervous system, after 12-18 months of infection was observed. Bioluminescent analysis of healthy females crossed with infected males showed that 50%, 62.5% and 37.5% of the female mice were subsequently positive for parasites in their ovaries, uteri and brain respectively. Although PCR confirmed the presence of parasites in the uterus of one of these mice, the blood of all mice was negative by PCR and LAMP. Subsequently, bioluminescent imaging of the offspring of infected female mice crossed with healthy males indicated parasites were present in the reproductive organs of both male (80%) and female (60%) offspring. These findings imply that transmission of T. b. gambiense 1135 occurs horizontally, most probably via sexual contact, and vertically in a murine model, which raises the possibility of a similar transmission in humans. This has wide reaching implications. Firstly, the observations made in this study are likely to be valid for wild animals acting as a reservoir for T. b. gambiense. Also, the reproductive organs may act as a refuge for parasites during drug treatment in a similar manner to the central nervous system. This could leave patients at risk of a relapse, ultimately allowing them to act as a reservoir for subsequent transmission by tsetse and possibly, horizontally and vertically. PMID:26735855

    Aquaporins (AQPs) are integral membrane channels responsible for the transport of water across a cell membrane. Based on reports that AQPs are present and accumulate in the female reproductive tract late in pregnancy, our aim was to study the expression of AQP isoforms (AQP1, 2, 3, 5, 8, and 9) at the end of pregnancy in rat in order to determine if they play a role in parturition. Reverse-transcriptase PCR revealed that specific Aqp mRNAs were detectable in the myometrium of non-pregnant and late-pregnancy (Days 18, 20, 21, and 22 of pregnancy) rat uteri. The expression of Aqp5 mRNA and protein were most pronounced on Days 18-21, and were dramatically decreased on Day 22 of pregnancy. In contrast, a significant increase was found in the level of Aqp5 transcript in whole-blood samples on the last day of pregnancy. The effect of oxytocin on myometrial Aqp5 expression in an organ bath was also investigated. The level of Aqp5 mRNA significantly decreased 5 min after oxytocin (10(-8) M) administration, similarly to its profile on the day of delivery; this effect was sensitive to the oxytocin antagonist atosiban. The vasopressin analog desmopressin (3.7 × 10(-8) M), on the other hand, did not alter the expression of Aqp5, but did increased the amount of Aqp2 mRNA, an effect that was atosiban-resistant. These results lead us to propose that oxytocin selectively influences the expression of Aqp5 at the end of pregnancy, and may participate in events that lead to parturition in the rat. The sudden increase of AQP5 in the blood on the last day of pregnancy may serve as a marker that indicates the initiation of delivery. PMID:24644013

    Aim: Sulfotransferase-catalyzed sulfation is the most important pathway for inactivating estrogens. Thus, activation of estrogen sulfotransferase (EST) may be an alternative approach for the treatment of estrogen-dependent breast cancer. In this study we investigated the involvement of EST in anti-breast cancer effects of the dithiocarbamate derivative TM208 in vitro and in vivo. Methods: The viability of human breast cancer MCF-7 cells was determined using a SBB assay. Nude mice bearing MCF-7 cells were orally administered TM208 (50 and 150 mg·kg−1·d−1) for 18 days. The xenograft tumors and uteri were collected. The mRNA expression of EST was examined with real-time PCR. EST protein was detected with Western blot, ELISA or immunohistochemical staining assays. A radioactive assay was used to measure the EST activity. Uterotropic bioassay was used to examine the uterine estrogen responses. Results: Treatment with TM208 (10, 15 and 20 μmol/L) concentration-dependently increased EST expression in MCF-7 cells in vitro. Co-treatment with triclosan, an inhibitor of sulfonation, abolished TM208-induced cytotoxicity in MCF-7 cells. TM208 exhibited an apparent anti-estrogenic property: it exerted more potent cytotoxicity in E2-treated MCF-7 cells. In the nude mice bearing MCF-7 cells, TM208 administration time-dependently increased the expression and activity of EST, and blocked the gradual increase of E2 concentration in the xenograft tumors. Furthermore, TM208 administration blocked the estrogens-stimulated uterine enlargement. Tamoxifen, a positive control drug, produced similar effects on the expression and activity of EST in vitro and in vivo. Conclusion: The induction of EST and reduction of estrogen concentration contribute to the anti-breast cancer action of TM208 and tamoxifen. TM208 may be developed as anticancer drug for the treatment of estrogen receptor-positive breast cancer. PMID:25937633

    Full Text Available BACKGROUND: The Gambia Hepatitis Intervention Study (GHIS was designed as a randomised control trial of infant hepatitis B vaccination applied to public health policy, with the main goal of preventing primary liver cancer later in adult life in The Gambia. To that effect, the National Cancer Registry of The Gambia (NCR, a population-based cancer registry (PBCR, was established in 1986 to actively collect data on all cancer diagnosis nation-wide. We extracted 20-years (1990-2009 of data to assess for the first time, the evolution of the most common cancers, also describe and demonstrate the role of the PBCR in a hepatitis B and liver cancer prevention programme in this population. METHODS AND FINDINGS: We estimated Age-Standardised Incidence Rates (ASR (W of the most common cancers registered during the period by gender. The registration period was divided into four 5-year intervals and incidence rates were estimated for each interval. The most common cancers in males were liver, prostate, lung plus bronchus, non-Hodgkin lymphoma (NHL and stomach, accounting for 60%, 5%, 4%, 5% and 3%, respectively. Similarly, cancers of the cervix uteri, liver, breast and NHL, were the most common in females, accounting for 33%, 24%, 11% and 4% of the female cancers, respectively. CONCLUSIONS: Cancer incidence has remained relatively stable over time, but as shown elsewhere in sub-Saharan Africa the disease is a threat in The Gambia. The infection related cancers which are mostly preventable (HBV in men and HPV/HIV in women were the most common. At the moment the data is not enough to detect an effect of hepatitis B vaccination on liver cancer incidence in The Gambia. However, we observed that monitoring case occurrence through PBCR is a key public health pre-requisite for rational planning and implementation of targeted interventions for improving the health of the population.

    Marsupials differ from eutherian mammals in their reproductive strategy of delivering a highly altricial young after a short gestation. The young, with its undeveloped organ systems completes its development post-natally, usually within a pouch. The young is dependent on milk with a composition that varies through lactation to support its growth and changing needs as it matures over a lengthy period. Gonadal differentiation occurs after birth, providing a unique opportunity to examine the effects of hormonal manipulations on its sexual differentiation of the highly accessible young. In marsupials a difference in the migration of the urinary ducts around the genital ducts from eutherian mammals results in the unique tammar reproductive tract which has three vaginae and two cervices, and two distinctly separate uteri. In the tammar wallaby, a small member of the kangaroo family, we showed that virilisation of the Wolffian duct, prostate and phallus depends on an alternate androgen pathway, which has now been shown to be important for virilisation in humans. Through hormonal manipulations over differing time periods we have achieved sex reversal of both ovaries and testes, germ cells, genital ducts, prostate and phallus. Whilst we understand many of the mechanisms behind sexual differentiation there are still many lessons to be learned from understanding how sex reversal is achieved by using a model such as the tammar wallaby. This will help guide investigations into the major questions of how and why sex determination is achieved in other species. This review discusses the control and development of the marsupial urogenital system, largely drawn from our studies in the tammar wallaby and our ability to manipulate this system to induce sex reversal.

    This study investigated the changes in establishment rates during the time course of a 6 week trickle infection of chickens with Ascaridia galli at two different dose levels, using a molecular marker. To differentiate early and late infection, two different egg cohorts (haplotype a and haplotype b, genetically identified using PCR-linked restriction fragment length polymorphism on the cox1 gene of the mitochondrial DNA) were used. Cohort-specific egg batches were produced by harvesting eggs from the uteri of female worms of the specific cohort. Fifty-six 8 week old Lohmann Brown Lite chickens were divided into seven groups and the infectivity of the egg batches was compared between two groups of chickens (P=0.6). The remaining chickens were allocated to four infection regimes and one control group. Group ab100 was trickle infected for 3 weeks with 100 eggs of haplotype a (twice weekly) followed by the same dose of eggs of haplotype b for another 3 weeks. Group ba100 was treated similarly but in the opposite order (haplotype b preceding a). A similar infection regime was applied for groups ab25 and ba25 but with a lower inoculation dose (25 eggs). All of the birds in these five groups (four infected and one control) were euthanased 2 weeks after the last inoculation. It was found that in the low-dose groups both the early and late infections established equally well, whereas in the high-dose groups the early infection was recovered in a significantly (P<0.001) higher proportion of chickens than the late infection, irrespective of genetic cohorts. Moreover, relatively higher proportions of the larvae from both the early and late infections were found in the posterior section of the small intestine. This result indicates the presence of dose-dependent resistance against reinfection and this resistance seems to act by reducing the establishment of late infection and by relocating the larvae from early infection.

  4. The value of prognostic factors for uterine cervical cancer patients treated with irradiation alone

    International Nuclear Information System (INIS)

    The aim of our study was to investigate and evaluate the prognostic value of and correlations between preclinical and clinical factors such as the stage of the disease, blood Hb level before treatment, size of cervix and lymph nodes evaluated by CT, age, dose of irradiation and duration of radiotherapy related to overall survival, disease-free survival, local control and metastases-free survival in cervical cancer patients receiving radiotherapy alone. 162 patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIA-IIIB cervical carcinoma treated with irradiation were analysed. Univariate and multivariate analyses using the Cox regression model were performed to determine statistical significance of some tumor-related factors. The Hb level before treatment showed significant influence on overall survival (p = 0.001), desease free survival (p = 0.040) and local control (p = 0.038). The lymph node status (>10 mm) assessed on CT had impact on overall survival (p = 0,030) and local control (p = 0,036). The dose at point A had impact on disease free survival (p = 0,028) and local control (p = 0,021) and the radiotherapy duration had showed significant influence on overall survival (p = 0,045), disease free survival (p = 0,006) and local control (p = 0,033). Anemia is a significant and independent prognostic factor of overall survival, disease-free survival and local control in cervical cancer patients treated with irradiation. The size of lymph nodes in CT is an independent prognostic factor for overall survival and local control in cervical cancer patients. The size of cervix uteri evaluated by CT has no prognostic significance in cervical cancer patients treated with radiotherapy. The prognostic value of FIGO stage of cervical cancer is influenced by other factors, analyzed in this study and is not an independent prognostic factor

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

    The objective of our study was to evaluate surgical outcome of minimally invasive vaginal hysterectomy (MIVH), using the bipolar vessel sealing system (BVSS; BiClamp®). The design was a retrospective analysis (Canadian Task-force Classification II-3). The setting was a secondary care hospital. Records of patients who underwent vaginal hysterectomy for benign indications in our centre between November 2005 and March 2011 were reviewed. The demographic patients' data, indications for surgery, patient history with regard to previous surgery, duration of surgery, blood loss (postoperative hemoglobin drop '∆Hb'), perioperative complications, and length of inpatient stay were collected from the medical records. The intervention was vaginal hysterectomy using BVSS (BiClamp®). Results showed that the mean duration of surgery was 48.9 ± 15.3 min (95% CI, 49.2-52.5). The mean duration of hospital stay was 3.2 ± 1.2 days (95% CI, 2.8-3.2). The mean ∆Hb was 1.4 ± 1.8 g/dl. Overall, conversion to laparotomy was required in three cases (0.6%). Only one haemoperitoneum occurred (0.2%) and this is the only case who required blood transfusion. The main indication for VH was uterine prolapse in 52.0% (n = 260) of cases; uterine fibroids in 37.4% (n = 187); adenomyosis uteri in 4.2% (n = 21); cervical dysplasia in 22 patients (4.4%) and in 2% (n = 10) of patients, endometrial hyperplasia and other pathologies were the indications for VH. It was concluded that electrosurgical bipolar vessel sealing by (BiClamp®) can provide a safe and feasible alternative to sutures in vaginal hysterectomy, resulting in reduced operative time and blood loss, with acceptable surgical outcomes.

    Full Text Available Es ist allgemein bekannt, daß die weltweit erste Schwangerschaft nach In-Vitro-Fertilisation (IVF in einer Eileiterschwangerschaft endete [1]. Seit damals wurde in zahlreichen Arbeiten die Problematik der Extrauterinschwangerschaft im Rahmen der Reproduktionsmedizin beschrieben. Die Inzidenz schwankt je nach Arbeit zwischen 2 und 11 %. Teilweise konnte man keine Risikofaktoren entdecken, andere Autoren beschreiben erhöhte Inzidenzen bei kleineren Cavi uteri. Manchmal wurden beschädigte Tuben insbesondere für ektope Schwangerschaften als Risiko erwähnt. Das Ziel einer eigenen Untersuchung und einer Literaturanalyse war, die Inzidenz der ektopen Schwangerschaft, insbesondere der heterotopen Schwangerschaft (gleichzeitig intrauteriner und extrauteriner Sitz und deren Besonderheiten im Rahmen eines IVF/ICSI-Programms herauszuarbeiten. Die Untersuchung von 19 ektopen Schwangerschaften nach IVF aus dem eigenen Klientel und der Vergleich mit der Literatur hat ergeben, daß diese nach reproduktionsmedizinischen Eingriffen gehäuft vorkommen, wobei insbesondere tubare Faktoren mit nachfolgender IVF und weniger ICSI dafür verantwortlich sind. Von besonderer Wichtigkeit ist, daß zwar die Progesteronwerte im Vergleich zu spontan entstandenen Schwangerschaften erhöht sind, nicht jedoch β -hCG-Werte bzw. deren Anstieg. Weiters ist darauf zu achten, daß heterotope Schwangerschaften, also die Kombination von intra- und extrauterinen Graviditäten, ungleich häufiger vorkommen und in die diagnostischen Überlegungen unbedingt miteinbezogen werden müssen. Leider ist die Existenz einer derartigen heterotopen Schwangerschaft mit gleichzeitigem Vorkommen einer Überstimulation vor Eintritt einer Ruptur gelegentlich undiagnostizierbar.

    Objective: The aim of the study was to investigate the cancer incidence and mortality in Huai'an area, China, from 2009 to 2011. Methods: The data about cancer incidence and mortality were provided by Huai'an Cancer Registry, China. Incidence and mortality rates, and standardized rates were calculated by age, gender, areas (urban and rural areas of Huai'an)and cancer sites. Results: The crude incidence rate for all cancer sites was 205.60/105 and the standardized incidence rate was 166.22/105. Both the crude and standardized rates were higher in urban area than in rural area for both sexes. The incidence rates increased in people aged 40 and over, and the peak ages of incidence were between 70-75 in both males and females. The crude mortality rate for all cancer sites was 153.88/105 and the standardized mortality rate was 122.14/105. Both the crude and standardized rates were similar in urban and rural areas for both men and women. The mortality rates were at low level under the age 50 in both sexes, but increased after the age 50, reaching the peak at the ages of 80-85 in both males and females. The top 10 most common cancer sites in rank were esophagus, stomach, lung, liver, colon-rectum, breast,pancreas, cervix uteri, brain and central nervous system, and leukemia, accounting for 87.56% of all cancers. The top 10 most leading causes of cancer death in order were cancers of esophagus, lung, liver, stomach, colon-rectum, pancreas, brain and central nervous system, leukemia, breast and lymphoma, accounting for 90.53% of all cancer deaths. Conclusion: Cancer is one kind of major diseases threatening people's health in Huai'an area, China. Cancer prevention and control should be enhanced, especially for esophageal cancer.

    Full Text Available INTRODUCTION. The incidence of cancer among residents in sites contaminated by pollutants with a possible health impact is not adequately studied. In Italy, SENTIERI Project (Epidemiological study of residents in National Priority Contaminated Sites, NPCSs was implemented to study major health outcomes for residents in 44 NPCSs. METHODS. The Italian Association of Cancer Registries (AIRTUM records cancer incidence in 23 NPCSs. For each NPCSs, the incidence of all malignant cancers combined and 35 cancer sites (coded according to ICD-10, was analysed (1996-2005. The observed cases were compared to the expected based on age (5-year period,18 classes, gender, calendar period (1996-2000; 2001-2005, geographical area (North-Centre and Centre-South and cancer sites specific rates. Standardized Incidence Ratios (SIR with 90% Confidence Intervals were computed. RESULTS. In both genders an excess was observed for overall cancer incidence (9% in men and 7% in women as well as for specific cancer sites (colon and rectum, liver, gallbladder, pancreas, lung, skin melanoma, bladder and Non Hodgkin lymphoma. Deficits were observed for gastric cancer in both genders, chronic lymphoid leukemia (men, malignant thyroid neoplasms, corpus uteri and connective and soft-tissue tumours and sarcomas (women. DISCUSSION. This report is, to our knowledge, the first one on cancer risk of residents in NPCSs. The study, although not aiming to estimate the cancer burden attributable to the environment as compared to occupation or life-style, supports the credibility of an etiologic role of environmental exposures in contaminated sites. Ongoing analyses focus on the interpretation of risk factors for excesses of specific cancer types overall and in specific NPCSs in relation to the presence of carcinogenic pollutants.

    Compared with lymphoid tissues, the immune cell compartment at mucosal sites is enriched with T cells bearing the γδ T-cell receptor (TCR). The female reproductive tract, along with the placenta and uterine decidua during pregnancy, are populated by γδ T cells predominantly expressing the invariant Vγ6(+)Vδ1(+) receptor. Surprisingly little is understood about the function of these cells. We found that the majority of γδ T cells in the non-pregnant uterus, pregnant uterus, decidua and placenta of mice express the transcription factor RORγt and produce interleukin-17 (IL-17). In contrast, IFNγ-producing γδ T cells were markedly reduced in gestational tissues compared with uterine-draining lymph nodes and spleen. Both uterine-resident invariant Vγ6(+) and Vγ4(+) γδ T cells which are more typically found in lymphoid tissues and circulating blood, were found to express IL-17. Vγ4(+) γδ T cells were particularly enriched in the placenta, suggesting a pregnancy-specific recruitment or expansion of these cells. A small increase in IL-17-producing γδ T cells was observed in allogeneic compared with syngeneic pregnancy, suggesting a contribution to regulating the maternal response to paternally-derived alloantigens. However, their high proportions also in non-pregnant uteri and gestational tissues of syngeneic pregnancy imply a role in the prevention of intrauterine infection or quality control of fetal development. These data suggest the need for a more rigorous evaluation of the role of IL-17 in sustaining normal pregnancy, particularly as emerging data points to a pathogenic role for IL-17 in pre-eclampsia, pre-term birth, miscarriage and maternal immune activation-induced behavioral abnormalities in offspring.

    The pattern of changes in the trypsin inhibition activities (TIA) of blood plasma, cervical mucus and the morphological structure of the cervix was studied in ewes exposed to 60Co radiation for seven and five days, the radiation doses being 6.7 Gy and 4.8 Gy, respectively. During exposure, the group of ewes irradaited with 4.8 Gy was given the Roboran vitamin addition and following irradiation ampicillin (5250 mg). TIA was determined from retardation of the hydrolysis of the synthetic substrate N-alpha-tosyl-p-nitroanilide by bovine trypsin; the TIA was expressed as the percentage of inhibited trypsin. Almost all the studied TIA values of blood plasma and cervical mucus were increased in the irradiated animals, the range being from 103.1 to 155.0% of the levels for non-irradiated ewes. A reduction was recorded only in the total TIA of blood plasma in the group irradiated with a dose of 6.7 Gy (83.1% of the values for non-irradiated animals). In the group of animals irradiated with 4.8 Gy and non Roboran administered, the TIA of cervical mucus was observed to decrease to 92.4%. It was found during the study of changes in the proportion of glands in the stroma and changes in epithelium thickness in the mucous membrane of the cervix uteri that the irradiated ewes had the epithelium thickness reduced to 95.3% to 65.5% and that their stromal gland number decreased to 75.4% to 79.7% of that recorded in non-irradiated animals. It was only in the group given the Roboran supplement that an increase to 123.7% of the gland number for untreated ewes was recorded on the tenth day after termination of the irradiation

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

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

    Full Text Available Background: The anatomical variations of uterus particularly those concerning the body of uterus are well known in medical literature. Knowledge of these variations is important in reproductive periods of life, as well as in deciding the surgical procedures involving caesarean section delivery. However there are some exceptional variations in the body of uterus that may puzzle the obstetrician and gynaecologist dealing with gynaecological patients. Normal development of the female reproductive tract requires a complex series of events. Failure of any part of this process can result in congenital anomaly. Careful sonography and an awareness of the sonographic findings of early pregnancy in anomalous uteri should improve the detection of these anomalies. Recognition of such anomalies will also allow differentiation of those patients requiring repeat dilatation and curettage from those requiring laparotomy, as in the presence of a blind uterine horn or ectopic gestation. 3D ultrasonography permits the obtaining of planar reformatted sections through the uterus, which allow precise evaluation of fundal indentation & length of the septum. Aim This study was undertaken to assess the morphology of uterus and evaluate the anomalies. Materials: 1500 subjects within the age of 15-45 were assessed using ultrasound scan and the anomalies were analyzed. Results: 5-7% cases involving the variations of morphology of the uterus were reported in this study, that 3DUS has recently become the only mandatory step in the initial investigation. Conclusion: With timely and accurate diagnosis, appropriate management is likely to provide the best possible outcome for all such patients.

    Full Text Available Toxoplasmosis is a major cause of foodborne disease, congenital complication and morbidity. There is an urgent need for safe and effective therapies to encounter congenital and persisting toxoplasmosis. The hypothesis was: Combination Diclazuril plus Atovaquone to exert a novel therapeutic synergy to prevent toxoplasmosis syndromes. Methods. Pregnant dams were treated with Diclazuril and Atovaquone monotherapy or combination therapy and infected intraperitoneally with Toxoplasma tachyzoites (600. Results. Infected dams developed severe toxoplasmosis associated syndrome with increases in the abdominal adiposity surrounding uteri, gansterointestinal and other internal organs and excessive weight gain. Numerous organisms along with infiltration of inflammatory cells were detected scattered into adipose tissues. Combination therapy (p< 0.01 and to a lesser extent Diclazuril (p< 0.05 protected dams from inflammatory fat and excess weight gains. This was consistent with pancreatitis development in infected dams (versus normal p< 0.05 with infiltration of inflammatory cells, degeneration and necrosis of pancreatic cells followed by the degeneration and loss of islets. Combination and monotherapy protected dams from these inflammatory and pathological aspects of pancreatitis. Infected dams exhibited severe colitis, and colonic tissues significantly shortened in length. Brush border epithelial cells were replaced with infiltration of lymphocytes, granulocytes, and microabscess formations into cryptic microstructures. Combination therapy synergistically preserved colonic structure and normalized pathological damages (p< 0.001 and to a lesser degree Diclazuril monotherapy protected dams from colitis (p< 0.05 and gastrointestinal toxoplasmosis. Other complications included severe splenitis (p<0.001 and hepatitis (p<0.001 which were normalized with combination therapy. Conclusions. Combination Diclazuril plus Atovaquone was safe and with a novel therapeutic

  16. Sex-dependent response of some rat biochemical, histological and embryological features to Squalene administration or/ and gamma radiation exposure

    Squalene, an intermediate of cholesterol biosynthesis, is known to possess potent antioxidant properties. The objective of the current study was to evaluate the influence of Squalene on some radiation-induced biochemical, histological and embryological changes in Sprague Dawley rats. Squalene was orally administered to rats (5 ml/kg/day) throughout 60 days before whole body gamma irradiation with 4 Gy. In adult male and female rats, the results revealed that Squalene has modulated the radiation produced abrupt elevation of total cholesterol (TC), triglycerides (TG) and and low density lipoprotein-cholesterol (LDL-C) levels and reduction of high density lipoprotein-cholesterol (HDL-C) ones in both male and female serum and male liver samples whereas it could not control the abrupt increase of HDL-C and decline of LDL-C in female liver values. Also Squalene has modified the histopathological acquired radiation lesions of both male and female colonic and hepatic tissues yet the female tested colonic sections showed moderate regeneration of crypts and villi layers whereas the hepatic sections yet displayed apparent hemorrhage and fatty liver infiltration of inflammatory cells. However, in the mated male rats and their pregnant counterparts, Squalene considerably restored the radiation induced male and female sex hormonal abrupt changes especially in female rats. Squalene administration to pergnant rats before irradiation at gestational day 17 improved the fetal survival ability as identified by the disappearance of resorption sites in the tested maternal uteri. Hence, it could be concluded that Squalene radioprotective capability surpassed the adult male rats than the female ones though it specified the pregnant females by protecting their growing embryos against radiation induced intrauterine fatal effect

    This study aimed to determine the mechanism by which H9N2 avian influenza virus (AIV) affects eggshell quality. Thirty-week-old specific pathogen free egg-laying hens were inoculated with the chicken-origin H9N2 AIV strain (A/Chicken/shaanxi/01/2011) or with inoculating media without virus by combined intraocular and intranasal routes. The time course for the appearance of viral antigen and tissue lesions in the oviduct was coincident with the adverse changes in egg production in the infected hens. The viral loads of AIV have a close correlation with the changes in the uterus CaBP-D28k mRNA expression as well as the Ca concentrations in the eggshells in the infected hens from 1 to 7 days post inoculation (dpi). Ultrastructural examination of eggshells showed significantly decreased shell thickness in the infected hens from 1 to 5 dpi (P shell surface and shell membrane were detected in the infected hens from 1 to 5 dpi as compared with the control hens. In conclusion, this study confirmed that H9N2 AIV strain (A/Chicken/shaanxi/01/2011) infection is associated with severe lesions of the uterus and abnormal expression of CaBP-D28k mRNA in the uteri of the infected hens. The change of CaBP-D28k mRNA expression may contribute to the deterioration of the eggshell quality of the laying hens infected with AIV. It is noteworthy that the pathogenicity of H9N2 AIV strains may vary depending on the virus strain and host preference. PMID:26915662

  18. Malformations Induced in Pregnant Rats and their Fetuses Treated with Fluconazole and / or Gamma Radiation

    International Nuclear Information System (INIS)

    The purpose of the present work is to study the synergistic effect of antifungal (fluconazole) treatment and / or g-radiation stress on pregnant mothers and their developing embryos by evaluating the maternal biochemical changes, embryological and histopathological lesions. Fluconazole is a broad-spectrum azole antifungal medication used for the treatment of several types of fungal infections including common forms such as vaginal candidiasis. Fluconazole (50 mg/kg b.wt.) was daily administered by oral gavage to pregnant rats from the 4th to the 13th gestational days during which they were subjected to g-radiation at a dose level of 1 Gy given at the 6th day (post implantation period) and 1 Gy on the 12th day (organogenesis period) of gestation. The animals were dissected and examined on the 20th day of gestation (one day prior to praturation). Fluconazole and radiation dual treatment resulted in increased maternal serum of lactate dehydrogenase (LDH), creatine phosphokinase (CPK), aspartate transaminase (AST) activities and sodium (Na+) level accompanied with a decline in potassium (K+) concentration. The results showed that there was an elevation in the lipid peroxidation end product malondialdehyde (MDA) as well as nitric oxide (NO) in the brain and heart tissues of pregnant rats. Meantime, the developing embryos in the uteri showed various teratological, skeletal and histological impairments. Moreover, the fluconazole treatment and / or g-radiation harm effects were detected as growth retardation, malformations, intrauterine death and embryonic resorption. The examination of the endoskeletal system of fetuses showed retardation in the ossification of the skull bones and lack of ossification at the center of vertebrae and appendages. In addition, the embryonic histological examinations revealed heart loss of normal architecture, the interstitial tissues were oedematous and containing necrotic cellular debris together with fibrosis of nerve cells in the brain of

    There is growing evidence that early life exposure to endocrine disrupting chemicals might increase the risk for certain adult onset diseases, in particular reproductive health problems and hormone dependent cancers. Studies in rodents suggest that perinatal exposure to even low doses of estrogenic substances can cause adverse effects, including epigenetic reprogramming of the prostate and increased formation of precancerous lesions. We analyzed the effects of an in utero exposure to the strongest natural estrogen, estradiol-17β, in a pig model. Two different low and one high dose of estradiol-17β (0.05, 10 and 1000 μg/kg body weight/day) were orally applied to gilts during pregnancy and potential effects on the reproductive system of the offspring were analyzed. No significant effects on sperm vitality parameters and testes size were observed in adult boars. However, prenatal exposure to the high dose decreased absolute, but not relative weight of the testes in prepubertal piglets. RNA sequencing revealed significantly regulated genes of the prepubertal prostate, while testes and uteri were not affected. Notably, we found an increased prostate expression of CCDC80 and a decreased ADH1C expression in the low dose treatment groups. BGN and SPARC, two genes associated with prostate tumor progression, were as well more abundant in exposed animals. Strikingly, the gene body DNA methylation level of BGN was accordingly increased in the high dose group. Thus, while only prenatal exposure to a high dose of estrogen altered testes development and local DNA methylation of the prostate, even low dose exposure had significant effects on gene expression in the prostate of prepubertal piglet offspring. The relevance of these distinct, but subtle transcriptional changes following low dose treatment lacking a clear phenotype calls for further long-term investigations. An epigenetic reprogramming of the pig prostate due to prenatal estrogen cannot be neglected. PMID:27062901

    Full Text Available Bacterial infections and inflammation of the uterus are common in dairy cattle after parturition. In particular, pathogenic bacteria that cause endometritis have been the focus of research in cattle reproduction in the last ten years. The aim of the present study was to identify commensal lactobacilli in the bovine uterus and to examine their influence on the synthesis of pro-inflammatory factors in bovine endometrial epithelial cells in vitro. Lactobacillus species were isolated from healthy bovine uteri and further characterised. Bovine endometrial epithelial cells in the second passage (n = 5 animals were co-cultured with the autochthonous isolates L. buchneri, L. ruminis and L. amylovorus as well as with a commercially available L. vaginalis in different multiplicities of infection (MOI = 1, 5 and 10, respectively. Endometrial epithelial cells cultured without bacteria served as controls. At distinct points in time (2, 4 and 6 h total RNA was extracted from co-cultured epithelial cells and subjected to reverse transcription quantitative PCR of pro-inflammatory factors. Furthermore, the release of such factors by co-cultured epithelial cells was measured by ELISA or EIA after 24 and 48 h. L. ruminis and L. amylovorus induced increased interleukin (IL IL1A, IL6, IL8 and prostaglandin-endoperoxide synthase 2 mRNA levels and the release of IL8 and prostaglandin F(2α in endometrial epithelial cells compared with control cells. In contrast, L. buchneri did not significantly influence the expression and release of these factors. Toll-like receptors 2 and 6 transcripts were found unchanged in co-cultured and untreated epithelial cells in vitro. However, endometrial epithelial cells of each animal showed individual differences in the response to bacterial load. These results suggest that Lactobacillus species are present in the bovine uterus, revealing immunomodulatory properties.
