    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.

    Trends in breast, cervix uteri, corpus uteri and ovarian cancers in six population based cancer registries (Mumbai, Bangalore, Chennai, Delhi, Bhopal, and Barshi) were evaluated over a period of the last two decades. For studying trends we used a model that fits this data is the logarithm of Y=ABx which represents a Linear Regression model. This approach showed a decreasing trend for cancer of the cervix and increasing trends for cancers of breast, ovary and corpus uteri throughout the entire period of observation in most of the registries. The four cancers, breast, cervix, corpus uteri and ovary, constitute more than 50% of total cancers in women. As all these cancers are increasing, to understand their etiology in depth, analytic epidemiology studies should be planned in a near future on a priority basis.

    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.

    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.

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

  12. Chlamydia psittaci in ocular adnexa MALT lymphoma: a possible role in lymphomagenesis and a different geographical distribution

    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.

    Full Text Available Extraskeletal myxoid chondrosarcoma is a rare soft-tissue sarcoma, mostly occurring in the proximal extremities and limb girdle. 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.

    Cancer is one of the main causes of death among young and middle-aged females. In case of some cancer sites there is a possibility of undertaking an intervention, which would diminish the risk of death--to this group belongs first of all malignant neoplasm of cervix uteri. The date of beginning first cervix uteri cancer screening in Poland is approaching, therefore presenting epidemiological opening balance and possible scenarios of changes it worthwhile. This work uses data on morbidity and mortality due to malignant neoplasm of cervix uteri cancer in Polish population. Time trends analysis was based on so-called "breakpoint" (joinpoint analysis). Cervix uteri cancer mortality trend is characterized by two breakpoints (1971 and 1993). In the period of 1963-1970 there was an increase of mortality and then after the trend reversed: percentage decline was estimated at the level of 0.8% yearly in 1971-1992 and 2.4% yearly in 1993-2002. Hypothetical scenarios of changes in cervix uteri cancer mortality show, that lack of intervention will cause mortality among Polish females at the level recorded in Finland 25 years ago. Optimistic variant would allow on diminishing mortality in Poland down to the level observed currently in Finland, in around 30 years. Implementing preventive cervix uteri cancer screening is currently the most urgent challenge of public health. If the preventive screening program will still be in the phase of plans and projects, then in 30 years time Poland will be in the point which Finland reached in the end of 1970s, and our civilizing underdevelopment will reach half a century.

    O. V. Kurmyshkina

    2011-01-01

    Full Text Available Early response genes are a group of proto-oncogenes that are the first to be activated in cell stimulation with different growth factors and to be involved in the regulation of cell proliferation and differentiation. Large amount of information supporting that altered expression of these genes is one of the central and earliest events of carcinogenesis has been accumulated. In this connection, it is promising to use early response genes as diagnostic and prognostic markers for the detection and combination therapy of cancer of the cervix uteri, one of the most common gynecological malignancies characterized by high mortality rates and difficulties in early diagnosis. The theoretical basis for these promises is the found mechanisms for the interaction of early response genes with human papillomavirus genome, the main cause of cervix uteri cancer.

    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

    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

    We investigated the function and expression of voltage-gated Na(+) channels (VGSC) in the uteri of nonpregnant rats using organ bath techniques, intracellular [Ca(2+)] fluorescence measurements, and RT-PCR. In longitudinally arranged whole-tissue uterine strips, veratridine, a VGSC activator, caused the rapid appearance of phasic contractions of irregular frequency and amplitude. After 50-60 min in the continuous presence of veratridine, rhythmic contractions of very regular frequency and slightly increasing amplitude occurred and were sustained for up to 12 h. Both the early and late components of the contractile response to veratridine were inhibited in a concentration-dependent manner by tetrodotoxin (TTX). In small strips dissected from the uterine longitudinal smooth muscle layer and loaded with Fura-2, veratridine also caused rhythmic contractions, accompanied by transient increases in [Ca(2+)](i), which were abolished by treatment with 0.1 microM TTX. Using end-point and real-time quantitative RT-PCR, we detected the presence of the VGSC alpha subunits Scn2a1, Scn3a, Scn5a, and Scn8a in the cDNA from longitudinal muscle. The mRNAs of the auxiliary beta subunits Scbn1b, Scbn2b, Scbn4b, and traces of Scn3b were also present. These data show for the first time that Scn2a1, Scn3a, Scn5a, and Scn8a, as well as all VGSC beta subunits are expressed in the longitudinal smooth muscle layer of the rat myometrium. In addition, our data show that TTX-sensitive VGSC are able to mediate phasic contractions maintained over long periods of time in the uteri of nonpregnant rats.

    Full Text Available Human papillomaviruses (HPV infection are considered as a triggering factor of cervical neoplastic events (e.g., CIN and are responsible for many cutaneous and mucosal lesions of cervix uteri. CIN commonly emerges from benign cervical tissue changes. There is clear evidence that local immune response in reproductive system plays a major role in the control and course of benign cervical tissue changes. Neutrophils play main role in encountering pathogens, primary antigen reactions and mediate powerful inflammatory effects. They are involved into development of antitumor response. The main purpose of our investigation was to study some indexes of neutrophil functional activity in women with CIN II-III associated with HPV-infection. It was shown that considerable changes in functional activity of neutrophils in mucous cervical secretions from women with CIN II-III, as compared to patients with chronic inflammation, accompanied by benign cervical changes (cervical ectopia. The alterations of neutrophil functional activity in women with CIN II-III may sustain a local chronic inflammation, associated with HPV-infection, thus increasing probability and predicting a of higher-grade tumor disease.

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

  14. 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.

    Full Text Available The experience with serial renal scintigraphy demonstrated its high informative value and safety in evaluating the severity of intrarenal urine outflow disorders; however, failure to make an objective assessment of ureteral patency considerably limits its study. The set of studies, which is given in this paper, is devoted to precisely this, highly urgent, problem. The authors describe an original procedure for diagnosing impaired urine outflow along the ureters, which has been used during serial renal scintigraphy, define the visual and digital characteristics of normal and impaired urine outflow in the supravesical segment, and denote the criteria characterizing severe impair- ments of renal urine derivation along the ureters. Risk factors for urine outflow disorders have been identified in patients with cancer of the cervix uteri, who receive various treatment modalities.

    We studied the cell-type-specific and temporal expression of c-fos and c-jun protooncogenes after 17beta-estradiol (E2) stimulation in the uteri of immature 3-week-old mice neonatally exposed to diethylstilbestrol (DES), DES-mice, and the ontogenic expression of these genes in the uteri of DES-mice using immunohistochemistry and in situ hybridization. A single E2 injection induced the transient and rapid expression of c-fos mRNA and c-Fos protein in the endometrial epithelium and endothelial cells of the blood vessels in both 3-week-old vehicle-treated controls and DES-mice; a peak of mRNA expression was 2 hours after E2 injection and that of protein expression was 2 to 3 hours after the injection. The expression of c-fos mRNA and protein after E2 stimulation was lower in the DES-mice than in the control animals. There were no significant differences in the c-jun expression patterns in both experimental groups before and after the E2 injection. The E2 injection transiently down-regulated the c-jun expression in the epithelium and up-regulated it in the stroma and myometrium. The uterine epithelium of DES-mice showed much stronger c-Jun immunostaining on days 4 and 10, compared with those of controls. Neonatal DES treatment reduced c-Jun immunoreactivity in the uterine epithelium on days 4 and 10, and increased the reaction in the stroma on day 4. These results suggested that the neonatal DES treatment induces permanent changes in the c-fos expression pattern independent of the postpuberal secretion of ovarian steroids. The changes in the expression of c-fos and c-jun protooncogenes, particularly during postnatal development, are likely to play important roles in the production of uterine abnormalities in the DES-mice.

    French uterine cancer recordings in death certificates include 60% of "uterine cancer, Not Otherwise Specified (NOS)"; this hampers the estimation of mortalities from cervix and corpus uteri cancers. The aims of this work were to study the reliability of uterine cancer recordings in death certificates using a case matching with cancer registries and estimate age-specific proportions of deaths from cervix and corpus uteri cancers among all uterine cancer deaths by a statistical approach that uses incidence and survival data. Deaths from uterine cancer between 1989 and 2001 were extracted from the French National database of causes of death and case-to-case matched to women diagnosed with uterine cancer between 1989 and 1997 in 8 cancer registries. Registry data were considered as "gold-standard". Among the 1825 matched deaths, cancer registries recorded 830 cervix and 995 corpus uteri cancers. In death certificates, 5% and 40% of "true" cervix cancers were respectively coded "corpus" and "uterus, NOS" and 5% and 59% of "true" corpus cancers respectively coded "cervix" and "uterus, NOS". Miscoding cervix cancers was more frequent at advanced ages at death and in deaths at home or in small urban areas. Miscoding corpus cancers was more frequent in deaths at home or in small urban areas. From the statistical method, the estimated proportion of deaths from cervix cancer among all uterine cancer deaths was higher than 95% in women aged 30-40 years old but declined to 35% in women older than 70 years. The study clarifies the reason for poor encoding of uterus cancer mortality and refines the estimation of mortalities from cervix and corpus uteri cancers allowing future studies on the efficacy of cervical cancer screening.

    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.

    Changes in the uterus expression of carbonic anhydrase (CA) II, III, IX, XII, and XIII were investigated under the influence of sex-steroids in order to elucidate mechanisms underlying differential effects of these hormones on uterine pH. Uteri of ovariectomised rats receiving over three days either vehicle, estrogen, or progesterone or three days estrogen followed by three days either vehicle or progesterone were harvested. Messenger RNA (mRNA) and protein levels were quantified by real-time PCR and Western blotting, respectively. The distribution of CA isoenzymes proteins were examined by immunohistochemistry. The levels of CAII, III, XII, and XIII mRNAs and proteins were elevated while levels of CAIX mRNA and protein were reduced following progesterone-only and estrogen plus progesterone treatment, compared to the control and estrogen plus vehicle, respectively. Following estrogen treatment, expression of CAII, IX, XII, and CAXIII mRNAs and proteins were reduced, but remained at a level higher than control, except for CAIX, where its level was higher than the control and following progesterone treatment. Under progesterone-only and estrogen plus progesterone influences, high levels of CAII, III, XII, and XIII were observed in uterine lumenal and glandular epithelia and myometrium. However, a high level of CAIX was observed only under the influence of estrogen at the similar locations. In conclusion, high expression of CAII, III, XII, and XIII under the influence of progesterone and estrogen plus progesterone could result in the reduction of uterine tissue and fluid pH; however, the significance of high levels of CAIX expression under the influence of estrogen remains unclear.

  6. 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

Methods: The 5-year survival rate and the factors influencing the prognosis of 512 cases of uteri were analyzed retrospectively. Results: The 5-year survival rate after radiotherapy was as follows: stage Ⅰ: 100%; stage Ⅱ: 74.5%; stage Ⅲ: 56.5%; stage Ⅳ: 28.6%. Overall 5-year survival rate was 65.4%, which was almost the same as traditional intracavitary injection (65.7%). The 5-year survival rate in cervix lesions more than 4 cm and those less than or equal to 4 cm in stage Ⅱ was 63.9% and 79.3%,respectively, with statistically significant difference (P<0.05). The 5-year survival rate of the patients with squamous carcinoma in stage Ⅱ was 77.0% and that with low differentiated squamous carcinoma was 64.0%respectively. Twenty-three (4.5%) out of 512 suffered from post-radiotherapy rectitis, 18 (3.5%) cystitis.Conclusion: the survival rate of the patients with cervix carcinoma subject to radiotherapy is stabilized to 65%. The diameter and pathological classes affect survival rate, respectively. Low radiotherapy dose decrease complications.

    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

    Full Text Available Under progesterone (P dominance, fluid loss assists uterine closure which is associated with pH reduction. 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.

    Quercetin could have profound effects on uterine morphology and proliferation, which are known to be influenced by estrogen. This study investigated the effect of quercetin on these uterine parameters in the presence and in the absence of estrogen. Ovariectomized adult female rats received peanut oil, quercetin (10, 50, and 100 mg/kg/day), estrogen, or estrogen+quercetin (10, 50, or 100 mg/kg/day) treatment for 7 consecutive days. At the end of the treatment, uteri were harvested for histological and molecular biological analyses. Distribution of proliferative cell nuclear antigen (PCNA) protein in the uterus was observed by immunohistochemistry. Levels of expression of PCNA protein and mRNA in uterine tissue homogenates were determined by Western blotting and real-time polymerase chain reaction, respectively. Our findings indicated that administration of 10 mg/kg/day of quercetin either alone or with estrogen resulted in decreased uterine expression of PCNA protein and mRNA with the percentage of PCNA-positive cells in uterine luminal and glandular epithelia markedly reduced compared with estrogen-only treatment. Changes in uterine morphology were the opposite of changes observed following estrogen treatment. Treatment with 100 mg/kg/day of quercetin either alone or with estrogen resulted in elevated PCNA protein and mRNA expression. In addition, the percentages of PCNA-positive cells in the epithelia, which line the lumen and glands, were increased with morphological features mimicking changes that occur following estrogen treatment. Following 50 mg/kg/day quercetin treatment, the changes observed were in between those changes that occur following 10 and 100 mg/kg/day quercetin treatment. In conclusion, changes in uterine morphology and proliferation following 10 mg/kg/day quercetin treatment could be attributed to quercetin's antiestrogenic properties, while changes that occur following 100 mg/kg/day quercetin treatment could be attributed to

    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.

    Post-cloacal bones of gekkotans may be present as a single (medial) pair, two pairs (medial and lateral), or may be lacking. We, herein, demonstrate that the presence of a single medial pair is the ancestral condition for the Gekkota, that the lateral pair is of sporadic occurrence within and between families, except for the Eublepharidae where it is universal, and that absence is also of sporadic occurrence except for the Sphaerodactylidae where it is the ancestral condition. Adult male Tokay geckos (Gekko gecko) possess only the medial pair of bones, and these exhibit a regionally-specific expression of woven, fibrolamellar, and lamellar bone, and an enclosed medullary cavity. Females and small juvenile males lack bony elements but exhibit a conspicuous band of dense connective tissue located about the anterior and lateral margins of the cloacal sacs. As males grow and attain sexual maturity, the medial post-cloacal bones condense in this band of dense connective tissue, and are thus shown to be dermal ossifications, similar to osteoderms but with muscular associations (although this is also known for crocodylians). Based upon ontogenetic data we set forth a scenario to explain the loss of the medial post-cloacal bones in various lineages. Differential staining of the cloacal sacs failed to reveal any specialized glandular structures. Investigation of the post-cloacal spurs shows them to be associated with cellular connective tissue of a type similar to that found in the vicinity of the medial post-cloacal bones. This suggests that the lateral post-cloacal bones may also be dermal bones, but histological evidence is needed to corroborate this.

    Despite the fact that cosmetic products undergo rigorous testing to ensure they are safe for human use, some users report mild discomfort following their application. 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

    In koilocytotic dysplasia of the uterine cervix the DNA content in squamous cells was quantitated by cytophotometry in histological preparations stained according to Feulgen. Three patterns of DNA distribution in the squamous cells were found. In type one (21.4%) the cells had DNA content in the diploid and paradiploid zone of the histogram. In type two (35.7%) cells with triploid and tetraploid DNA values were found, but with a conspicuous modal class of cells. In type three no modal class cells were found (42.9%). The quantitative DNA changes in squamous cells show that some of the HPV induced alterations may be regarded as precancerous.

    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

    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 Primary squamous cell carcinoma of the endometrium is exceedingly rare. We report a case of 52 years old postmenopausal woman who presented with pelvic pain of four months duration. Gynecologic examination revealed a normal cervix. A possibility of pyometra was considered through pelvic ultrasound. Total abdominal hysterectomy was performed and histopathologically, it was diagnosed as a case of primary in situ squamous cell carcinoma of the endometrium.

    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 (Acta Oncol 2003; 42: 357-365). 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 cisplatin-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.

    For a long time, combined external irradiation and brachytherapy has been considered as the standard treatment in patients with advanced cervical cancers. Recently, five clinical randomized trials assessing the role of cis-platin-based chemotherapy delivered concomitantly to radiotherapy have been conducted in the United States. Another clinical randomized trial assessing the role of epirubicin was conducted by the Queen Mary Hospital in Hong Kong. With more than 2,000 enrolled patients, these studies showed converging results with an overall and disease-free survival improvement in the arms combining cis-platin and epirubicin-based chemotherapy and irradiation. These combinations led to a significant decrease in loco-regional evolution or recurrence rates, or even in pulmonary metastases rates. The relative risk of recurrences was decreased by 50%. The relative risk of death was decreased by 40%. The differences, however, were less significant in patients with advanced stages III or IVA. Hematological and digestive acute toxicity was significantly higher in the radiochemotherapy groups, but long-term complications were comparable. The results of these randomized trials have led to a modification in the standard of treatment in these poor prognosis cervix cancers. Five of the randomized trials evidenced the superiority of cis-platin-based chemotherapy, but the optimal chemotherapeutic regimens remain to be defined.

    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.

    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.

    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 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.

    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

    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.

    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.

    Full Text Available Abstract Background Cervical cancer (CC, a leading cause of cancer-related deaths in women worldwide, has been causally linked to genital human papillomavirus (HPV infection. Although a host of genetic alterations have been identified, molecular basis of CC development is still poorly understood. Results We examined the role of promoter hypermethylation, an epigenetic alteration that is associated with the silencing tumor suppressor genes in human cancer, by studying 16 gene promoters in 90 CC cases. We found a high frequency of promoter methylation in CDH1, DAPK, RARB, and HIC1 genes. Correlation of promoter methylation with clinical characteristics and other genetic changes revealed the following: a overall promoter methylation was higher in more advanced stage of the disease, b promoter methylation of RARB and BRCA1 predicted worse prognosis, and c the HIC1 promoter methylation was frequently seen in association with microsatellite instability. Promoter methylation was associated with gene silencing in CC cell lines. Treatment with methylation or histone deacetylation-inhibiting agents resulted in profound reactivation of gene expression. Conclusions These results may have implications in understanding the underlying epigenetic mechanisms in CC development, provide prognostic indicators, and identify important gene targets for treatment.

    Infestation of the living tissues of the eye, ocular adnexae or orbit by larvae of flies of the order Diptera is known as ophthalmomyiasis. 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.

  11. Three-dimensional dynamic MR hysterosalpingography: a preliminary report

    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.

    Full Text Available Amostras de macrófitas aquáticas foram coletadas de março de 1992 a fevereiro de 1993, nas lagoas do Guaraná (Eichhornia azurea e dos Patos (E. crassipes e E. azurea. Na lagoa do Guaraná, a maior densidade e a maior diversidade foram registradas nas águas altas, com dominância de Telebasis e Acanthagrion, enquanto na lagoa dos Patos a maior densidade e a maior diversidade foram verificadas na fase de águas baixas. Os táxons dominantes na lagoa dos Patos foram Telebasis, Acanthagrion, Neoneura (?,Coryphaeschna adnexa, Miathyria, Diastatops intensa e Erythemis. A lagoa dos Patos diferenciou-se da lagoa do Guaraná principalmente pela alta densidade de C. adnexa, Miathyria, D. intensa e Erythemis, sugerindo que a morfologia de E. crassipes abrigue maior número de invertebrados. A variação do nível hidrométrico dos rios influenciou na concentração de oxigênio dissolvido e pH. Essa variação foi um dos fatores determinantes na flutuação mensal da densidade das larvas. A diferença entre as lagoas, mostrada na análise DCA, deveu-se, principalmente, à variação da densidade de Odonata.Samples of aquatic macrophytes were collected on Guaraná (Eichhornia azurea and Patos (E. crassipes and E. azurea Lakes from March 1992 to February 1993. On Guaraná Lake the highest density and diversity were registered during the high water phase with dominance of Telebasis and Acanthagrion, while on Patos Lake, highest density and diversity were observed during the low water phase. The dominant taxa on Patos Lake were Telebasis, Acanthagrion, Neoneura (?,Coryphaeschna adnexa, Miathyria, Diastatops intensa and Erythemis. DCA and ANOVA differentiated Patos Lake mainly, because of the high abundance of C. adnexa, Miathyria, D. intensa and Erythemis which may be due to morphology of E. crassipes that shelters larger number of invertebrates. Water level variation of rivers influenced concentration of dissolved oxygen and pH. This variation was

    A 52-year-old patient presented with a painless nodular tumor of the upper left eyelid, which was first noticed 6 months prior to the initial presentation. The histopathological and immunohistochemical examination of the excised tumor revealed a mucinous sweat gland carcinoma. This very rare neoplasm (1/150,000 skin lesions) is located within the ocular adnexa in 40 % of cases. If completely excised the prognosis is usually good; however, due to the histological similarity to metastases of an adenocarcinoma, a hitherto unknown primary tumor at another site should be excluded.

    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.

    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

    Rhinosporidiosis is a chronic localized granulomatous disease caused by Rhinosporidium seeberi, an aquatic protistan parasite belonging to a clade, Mesomycetozoea. Infestation of Rhinosporidiosis to the eye and adnexa is termed oculosporidiosis, in such cases, conjunctival mucosa is mostly involved; however in our case, it involved only the lacrimal sac and deeper periorbital tissue and presented as a case of orbital swelling. Surgical excision of the lesion was done, postoperatively dapsone therapy was given for 6 months, and the patient responded very well with no recurrence till date. PMID:27003980

Uteri from pregnant, slaughtered animals (n = 47) were sampled. The surface of the uterus was wiped with alcohol, flame sterilized, and cut open.......1% (40/47) of pregnant cows contained bacteria. In 22 cows, the bacteria were localised within the endometrial tissue, whereas in the remaining 18 cows, the bacteria were on the epithelial surface. Placental samples were obtained from 43 cows, and 76.7% (33/43) of these contained bacteria. The presence...... of bacteria in the pregnant uterus may suggest that a cow can carry a pregnancy despite the presence of few potentially pathogenic bacteria or that normal flora exist in the uterus as in, for example, the vagina. In conclusion, bacteria were present in the endometrium and placentomes of pregnant cows. Further...

I...... as the lab space is rectangular and the recreational space is spherical. Third, I argue that NEEM scientists and Sloterdijk are essentially engaged in a common project: the scientists work hard to align air bubbles in the cores with atmospheric fluctuations in the hemisphere on the evidentiary terrain of ice......, and Sloterdijk attempts to connect micro-uteri with macro-uteri in an attempt to fundamentally rethink space. Fuller’s notion of ‘Spaceship Earth’, appropriated by Sloterdijk in his thinking about anthropogenic climate change, lends itself well to capturing the scalar alignments and the isolated NEEM base...

    1975-08-01

    Copper and iron in blood of 83 women with maligne tumors of the genitalia were regulary controled before, during and till 69 weeks after therapy. The relation between the copper/iron-ratio and the expansion and histology of the tumors, the success of the therapy and the incidence of a recurrence was checked for any significancy. Our results show the improtance of the ratio in the diagnosis and differentialdiagnosis of the ovarian-cancer and the corpus-uteri-cancer, and in the success-controll during tumor-therapy. In the group of the patients with collum-uteri-cancer we found a significant difference in the copper/iron-ratio of the patients with and without a recurrence during the controllperiod after therapy, which emphasizes the importance of this copper/iron-ratio.

    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.

    2008-03-01

    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.

    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.

    The purpose of this study were to evaluate the findings of gestational trophoblastic disease(GTD) at color Doppler imaging (CDI) and to assess the role of CDI in differentiating gestational trophoblastic tumor (GTT) from hydatidiform mole (H-mole). CDI findings of 18 patients with H-mole and 52 patients with GTT were reviewed. Masswas detected in 43(82,7%) patients with GTT. Thirty seven out of 43 masses showed varying degree of intratumoral flows. mean resistive index (RI) of intratumoral flow was 0.39+0.15. H-mole manifestated as a characteristic vesicular mass in 6 patients without history of curretage, while there was no definable mass in 12 patients with history of curretage. The masses of H-mole did not show intratumoral flow. Hypervascularity of adnexae was detected in 44 (84.6%) patients with GTT, whereas only six (33.3%) patients with H-mole showed minimalhypervascularity of adnexae. Mean RI of uterine arteries was 0.69+0.13 in GTT and 0.70+0.15 in H-mole. CDI findings of mass in the uterus, hypervascularity of adnexal region and intramural vessels in patients suspected to have GTD clinically, may suggest GTT. In conclusion, CDI was helpful in the diagnosis of GTD and the differentiation between H-mole and GTT

    Melatonin has a wide variety of beneficial actions at the level of the gonads and their adnexa. Some actions are mediated via its classic membrane melatonin receptors while others seem to be receptor-independent. This review summarizes many of the published reports which confirm that melatonin, which is produced in the ovary, aids in advancing follicular maturation and preserving the integrity of the ovum prior to and at the time of ovulation. Likewise, when ova are collected for in vitro fertilization-embryo transfer, treating them with melatonin improves implantation and pregnancy rates. Melatonin synthesis as well as its receptors have also been identified in the placenta. In this organ, melatonin seems to be of particular importance for the maintenance of the optimal turnover of cells in the villous trophoblast via its ability to regulate apoptosis. For male gametes, melatonin has also proven useful in protecting them from oxidative damage and preserving their viability. Incubation of ejaculated animal sperm improves their motility and prolongs their viability. For human sperm as well, melatonin is also a valuable agent for protecting them from free radical damage. In general, the direct actions of melatonin on the gonads and adnexa of mammals indicate it is an important agent for maintaining optimal reproductive physiology. PMID:23549263

    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: 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

    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 BACKGROUND: Asymmetric Gonadal dysgenesis ( AGD very rare intersex disorder seen in less than 5% of all intersex disorders. Asymmetric gonadal dysgenesis refers to individuals who have abnormal and symmetrical gonadal development , usually a differentiated gonad on one side and a steak gonad or steak testis on other side. The importance of identifying these lesions are important because risk of development of malignancy as high as 30% , which always influenced by y - chromosome. CASE REPORT : A 21 year old male patient presented with left s ided obstructed inguinal hernia with cryptorchidism. On exploratory laparotomy , uterus with bilateral adnexa and testis are seen. Microscopy revealed features of asymmetric gonadal dysgenesis. True hermaph - roditism was the closest differential diagnosis an d was excluded by the strict histological criteria necessary for diagnosis. CONCLUSION: Asymmetric gonadal dysgenesis is a rare disorder. The rare nature of this entity and its clinical implications merits its reporting.

    Leprosy is a chronic granulomatous disease caused by the bacillus Mycobacterium leprae. It primarily affects the skin and peripheral nerves and is still endemic in various regions of the world. Clinical presentation depends on the patient's immune status at the time of infection and during the course of the disease. Leprosy is associated with disability and marginalization. Diagnosis is clinical and is made when the patient has at least 1 of the following cardinal signs specified by the World Health Organization: hypopigmented or erythematous macules with sensory loss; thickened peripheral nerves; or positive acid-fast skin smear or skin biopsy with loss of adnexa at affected sites. Leprosy is treated with a multidrug combination of rifampicin, clofazimine, and dapsone. Two main regimens are used depending on whether the patient has paucibacillary or multibacillary disease.

    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

  5. 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.

    2014-01-01

    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.

    Full Text Available Trophoblastic disease of pregnancy is also called as gestational trophoblastic disease (GTD, a rare group of tumors that involves abnormal proliferation of the trophoblastic cells. GTD is generally benign but sometimes can be malignant due to its marked penetration into and destruction of myometrium as well as its ability to metastasize hence the groups of tumors are referred to as gestational trophoblastic neoplasm (GTN. These are among the rare tumors that can be cured even in the presence of widespread dissemination. Present study is a case of intrauterine partial mole with ectopic pregnancy in the right adnexa with vesicular changes, a rare entity in obstetrics.

    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.

    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.

    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.

    2011-01-01

    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.

    2016-01-01

    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 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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    Full Text Available Background/Aim. Hyperbaric oxygenation (HBO is a medical treatment of a patient with 100% oxygen inspiration under the pressure higher than atmospheric in a special unit designed to let the whole patient's body rest in a chamber. The aim of the study was to determine the effect of the application of HBO treatment on the patient's lower extremities with chonic inoperabile occlusive disease by measning the parameters of perfusion scintigraphy (perfusion reserve, relative perfusion. Methods. This investigation included 22 patients (19 males and 3 famales. Following clinical assessment of lower extremities condition according to the skin appearance and its adnexa, claudication distance was performed. Clinical condition was graded by the use of 5-point nominal scale. In all of the patients 99mTctetraphosmine lower extremities scintigraphy was done ten days prior to the treatment start and ten days after the treatment with HBO. Lower legs were imaged from the posterior view. Prior to imaging the patients were obligatory lying approximately half an hour. Results. In 18 (86% of the patients there was an improvement manifested as better subjective condition and better skin and its adnexa appearance. Following HBO treatment there was a statistically significant change in collecting the radiopharmac at rest. This finding indicates an increased viability of muscles as well as an increased perfusion reserve. Perfusion reserve mean values increased from 39.99 to 50.86%, and from 38.46 to 49.33% for the right and the left lower leg, respectively. This parameter clearly indicates favorable effects of HBO treatment pertaining neoangiogenesis and, consequently, increased viability of the lower leg muscles. It was also obvious in visual analysis of the obtained images. Conclusion. The obtained results confirm that muscle perfusion measured by the parameters of perfusion scintigraphy using 99mTc-tetrophosmine (perfusion reserve, relative perfusion in patients with

    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

  6. 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)

    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.

    The prevalence of diabetes mellitus (DM) is about 6% across the globe. This prevalence has been reported to increase in the near future. This means that the number of women with DM who would like to get pregnant and have children will also increase. The present study is aimed at investigating the morphological changes observed in the uterus after the onset of DM. The study also examined the pattern of distribution of nociceptin (NC), a neuropeptide involved in the regulation of pain, a major physiological factor during parturition. The study shows a severe atrophy of uteri as early as 15 days post DM and continued until the termination of the eight-week study. This atrophy was confirmed by light microscopy. Electron microscopy study showed atrophy of the columnar cells of the endometrium, reduced myofibril number and destruction of smooth muscle cells in the myometrium of diabetic rats compared to control. Immunofluorescence and immunoelectron microscopy studies clearly demonstrated the presence of NC in the endometrium, myometrium and on the myofibrils of the smooth muscles of both control and diabetic rat uteri. In addition, NC-positive neurons and varicose fibres were observed in the myometrium of both normal and diabetic rats. However, the expression of NC decreased after the onset of DM. Morphometric analysis showed that the number of NC-labeled cells was significantly (p < 0.05) lower in diabetic rat uteri compared to those of control. In conclusion, DM-induced uterine atrophy is associated with a decrease in the expression of NC in cells, neurons and myofibrils of the rat uterus. PMID:26589323

    In polytocous animals, blastocysts are evenly distributed along each uterine horn and implant. The molecular mechanisms underlying these precise events remain elusive. We recently showed that lysophosphatidic acid (LPA) has critical roles in the establishment of early pregnancy by affecting embryo spacing and subsequent implantation through its receptor, LPA3. Targeted deletion of Lpa3 in mice resulted in delayed implantation and embryo crowding, which is associated with a dramatic decrease in the prostaglandins and prostaglandin-endoperoxide synthase 2 expression levels. Exogenous administration of prostaglandins rescued the delayed implantation but did not rescue the defects in embryo spacing, suggesting the role of prostaglandins in implantation downstream of LPA3 signaling. In the present study, to know how LPA3 signaling regulates the embryo spacing, we determined the time course distribution of blastocysts during the preimplantation period. In wild-type (WT) uteri, blastocysts were distributed evenly along the uterine horns at Embryonic Day 3.8 (E3.8), whereas in the Lpa3-deficient uteri, they were clustered in the vicinity of the cervix, suggesting that the mislocalization and resulting crowding of the embryos are the cause of the delayed implantation. However, embryos transferred singly into E2.5 pseudopregnant Lpa3-deficient uterine horns still showed delayed implantation but on-time implantation in WT uteri, indicating that embryo spacing and implantation timing are two segregated events. We also found that an LPA3-specific agonist induced rapid uterine contraction in WT mice but not in Lpa3-deficient mice. Because the uterine contraction is critical for embryo spacing, our results suggest that LPA3 signaling controls embryo spacing via uterine contraction around E3.5.

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.

    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.

  18. The physiological expression of scavenger receptor SR-B1 in canine endometrial and placental epithelial cells and its potential involvement in pathogenesis of pyometra.

    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

    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.

    Estradiol-17β (E2) acts through the estrogen receptor (ER) to regulate uterine growth and functional differentiation. To determine whether E2 elicits epithelial mitogenesis through epithelial ER versus indirectly via ER-positive stromal cells, uteri from adult ER-deficient ER knockout (ko) mice and neonatal ER-positive wild-type (wt) BALB/c mice were used to produce the following tissue recombinants containing ER in epithelium (E) and/or stroma (S), or lacking ER altogether: wt-S + wt-E, wt-S...

    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.

    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

    Escherichia coli (E. coli) is the most commonly isolated infectious agent causing pyometra in bitches. Many E. coli strains isolated from the uteri of infected dogs carry several adhesin genes (fimH, papGIII and sfa). The objective of this study was to investigate the role of each adhesin gene product, acting alone or expressed in combination, in the bacterial binding to canine endometrium. E. coli strain P3, which was isolated from a uterus of a bitch naturally affected with pyometra, was shown by PCR to carry all three known fimbrial adhesin genes fimH, papGIII and sfa. Knockout (KO) mutants of this wildtype (P3-wt) strain were generated using insertional inactivation. Adhesion assays on anoestrous uteri of three post-pubertal bitches were undertaken. Overall, the number of bacteria adhering to canine endometrial biopsies was comparable between strains and no significant difference in the number of bound bacteria was found between the P3-wt strain and the single or double KO-strains. However, the triple knockout strain displayed less binding to the canine endometrium compared with the P3-wt strain. This study shows that a pathogenic E. coli strain (P3) isolated from the uterus of a bitch with pyometra was able to fully compensate for the loss of two of its three known adhesin genes. It was necessary to inactivate all three known adhesin genes in order to see a significant decrease in binding to canine endometrium. PMID:23523172

    AIM:We studied the estrogen receptor (ER) and progesterone receptor (PR) isoforms expression in gastric antrum and corpus of female gerbils and their regulation by estradiol (E2) and progesterone (P4).METHODS: Ovariectomized adult female gerbils were subcutaneously treated with E2,and E2 + P4.Uteri and stomachs were removed,the latter were cut along the greater curvature,and antrum and corpus were excised.Proteins were immunoblotted using antibodies that recognize ER-alpha,ER-beta,and PR-A and PR-B receptor isoforms.Tissues from rats treated in the same way were used as controls.RESULTS: Specific bands were detected for ER-alpha (68 KDa),and PR isoforms (85 and 120 KDa for PR-A and PR-B isoforrns,respectively) in uteri,gastric antrum and corpus.We could not detect ER-beta isoform.PR isoforms were not regulated by E2 or P4 in uterus and gastric tissues of gerbils.ER-alpha isoform content was significantly down-regulated by E2 in the corpus,but not affected by hormones in uterus and gastric antrum.CONCLUSION: The presence of ER-alpha and PR isoforms in gerbils stomach suggests that E2 and P4 actions in this organ are in part mediated by their nuclear receptors.

    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.

    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.

  9. 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

    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

    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.

    Human papillomavirus (HPV) is one of the most common sexually transmitted infections worldwide. Exposure to HPV is very common, and an estimated 65%-100% of sexually active adults are exposed to HPV in their lifetime. The majority of HPV infections are asymptomatic, but there is a 10% chance that individuals will develop a persistent infection and have an increased risk of developing a carcinoma. The International Agency for Research on Cancer has found that the following cancer sites have a strong causal relationship with HPV: cervix uteri, penis, vulva, vagina, anus and oropharynx, including the base of the tongue and the tonsils. However, studies of the aetiological role of HPV in colorectal and esophageal malignancies have conflicting results. The aim of this review was to organize recent evidence and issues about the association between HPV infection and gastrointestinal tumours with a focus on esophageal, colorectal and anal cancers. The ultimate goal was to highlight possible implications for prognosis and prevention. PMID:27672265

    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.

    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.

    Paralongidorus bullatus n. sp. from groundnut soils in Sador'é Niger is described and illustrated. It is distinguishable from most species of the genus by its body and odontostyle lengths, knob-like head, and digitate ending of the protoplasmic region of the tail. Length of the female body is 4.4-5.5 mm, of the odontostyle 132-156 mum, and of the tail 32-44 mum. Tail terminus is conoid to broadly rounded. Uteri are well developed, without sperms. Males are not found. Xiphinema parasetariae Luc 1958, a species inquirenda, is validated and, based on measurements and tail structures, X. attorodorum Luc 1961 is proposed as a synonym of X. parasetariae. Additional measurements are given for its females and juveniles.

    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.

  4. 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

    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

    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.

  7. Seasonal and age related changes in size of reproductive structures of red deer hinds (Cervus elaphus

    1992-10-01

    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.

    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).

    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.

    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.)

  13. EFFICACY OF INTRAPERITONEAL INTERFERON-α ADMINISTRATION FOR TREATMENT OF ENDOMETRIOSIS IN RATS

    R. V. Pavlov

    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. 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.

    Preterm births accounts for roughly 9% of all births worldwide and can have detrimental or even lethal consequences for the infant. However to develop new treatment that will lower the rate of preterm births, more knowledge is required on the factors contributing to the contraction and relaxation...... in the myometrium. Using Western blot the protein level of SK3 was found to increase in uteri from animals treated with 17β-estradiol, an effect that was not reflected at the mRNA level. The levels of mRNA for SK3 were significantly lower in the uterus of 17β-estradiol-treated animals than in the uterus...... of ovariectomized animals. We conclude that the SK channels are present in the endometrial epithelium, and possibly also in the myometrium of the rat uterus. Furthermore, the hormonal effect on SK3 caused by 17β-estradiol includes divergent regulation at mRNA and protein levels....

    Jordt, T; Lorenzini, E

    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

    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

    Deep trophoblast invasion is usually considered to be a unique feature of human placentation as compared to other primates. Because of the occasional occurrence of preeclampsia in great apes, which in the human is associated with impaired deep invasion, this uniqueness may be questioned. The availability of two well-documented pregnant chimpanzee uteri in the Hubrecht Collection (Museum für Naturkunde, Berlin) allowed us to evaluate the extent of trophoblast invasion in this species. By adjusting currently used protocols, we obtained successful immunohistochemical staining for cytokeratin and α-actin, as well as Ulex europaeus agglutinin 1 (UEA1) lectin staining, in this archival material. In both specimens interstitial trophoblast invasion had occurred in both decidua and myometrium. Because of a lack of published data on fetal growth for this species, fetal sizes (7cm and 13cm) could not be strictly related to gestational ages and thus be compared with the time-course of human trophoblast invasion. However, since the earlier specimen did not show any endovascular trophoblast invasion in spiral arteries - in contrast to pregnant human uteri with equivalent fetal sizes - endovascular migration seems to begin at a different gestational age in the chimpanzee. In the later specimen endovascular trophoblast was associated with spiral artery remodelling in the inner myometrium, and this invasion was extended to include a radial artery, which at that stage still showed relatively intact vascular smooth muscle and elastic lamina. We conclude that invasion depth and spiral artery remodelling are basically similar in chimpanzees and humans, although the seemingly different time of onset may have implications for uteroplacental oxygen supply and fetal development.

    Transcervical endometrial biopsy is a useful tool for obtaining information about uterine health in some species. The clinical application of information gained from histopathological interpretations of endometrial biopsies in the bitch has not been validated. We hypothesized that transcervical endometrial biopsy samples would be as diagnostic as full-thickness uterine sections in identifying cystic endometrial hyperplasia (CEH), inflammation and periglandular fibrosis. Endometrial biopsies were obtained from 20 female adult dogs. Vaginal swabs, gross appearance of the vulva and vaginal tract, and serum progesterone values were used to determine the stage of the oestrous cycle at the time of sampling. The uteri were removed between 1 and 6 days after the biopsy procedure, and full-thickness sections were collected from each uterine horn and ovary and processed for histopathology. Two pathologists, blinded to the origin of each sample, compared full-thickness sections from the excised uteri to the biopsy samples collected via the transcervical technique. Pathologic features noted included: CEH, inflammation and periglandular fibrosis. Pathological diagnoses obtained from the biopsy sections were compared with those obtained from the full-thickness sections, as well as comparing diagnoses between the two pathologists, using McNemar's test. Of the 59 total biopsy samples obtained, 54 were considered diagnostic. All stages of the canine oestrous cycle were represented (anoestrus, proestrus, oestrus and dioestrus). Pyometra was not noted in any of the transcervical biopsy sections, but was noted in many of the full-thickness sections collected from dogs in dioestrus, suggesting either that biopsy is not a sensitive indicator of pyometra or that the procedure may induce pyometra in dioestrous dogs. Transcervical endometrial biopsy showed similar sensitivity as full-thickness sections in detecting CEH, inflammation and fibrosis. No differences in describing lesions were

    Of 13 cancers that tend to occur at lower rates in aboriginal Americans or in the native lands of Japanese, Chinese, and Spanish-speaking persons than in United States whites, rates for all but one (laryngeal) have increased in migrants to the United States. In addition to leukemia, these 13 cancers include neoplasms that have been related, at least in part, to a diet high in animal fats or proteins (colon and rectum cancer); reproductive and endocrinologic factors and a diet high in animal fats or protein (prostate, ovary, corpus uteri, breast, and testis cancer); chemical carcinogens (lung, larynx, bladder, and pancreas cancer); and a common infectious agent that, like polio viruses, causes clinically overt disease with a frequency directly related to age of patient at initial infection (Hodgkin's disease). Of 9 cancers that occur at higher rates in aboriginal Americans or in one or more of the native lands of migrants than in United States whites, the rates of 5 tend to decrease in migrants. These include cancers that may be related to food preservation (stomach cancer); products of microorganisms that may contaminate foods (esophagus and liver cancer); and infectious agents (nasopharynx, cervix uteri, and liver cancer). In addition, rates of cancer of the thyroid are high in aboriginal Americans; those of the gallbladder are high in individuals of native American ancestry and in Japanese; incidence of salivary gland tumors is high in Alaskan natives and Colombians; and rates of kidney cancer are high in Alaskan natives. Five types of epidemiologic studies are described that should be conducted in the migrants and in their countries of origin and adoption to elucidate further the etiology of various neoplasms.

  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.

    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.

  3. 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.

  4. Uterine Epithelial Estrogen Receptor-α Controls Decidualization via a Paracrine Mechanism.

    2015-09-01

    Steroid hormone-regulated differentiation of uterine stromal cells, known as decidualization, is essential for embryo implantation. The role of the estrogen receptor-α (ESR1) during this differentiation process is unclear. Development of conditional Esr1-null mice showed that deletion of this gene in both epithelial and stromal compartments of the uterus leads to a complete blockade of decidualization, indicating a critical role of ESR1 during this process. To further elucidate the cell type-specific function of ESR1 in the uterus, we created WE(d/d) mice in which Esr1 is ablated in uterine luminal and glandular epithelia but is retained in the stroma. Uteri of WE(d/d) mice failed to undergo decidualization, indicating that epithelial ESR1 contributes to stromal differentiation via a paracrine mechanism. We noted markedly reduced production of the leukemia inhibitory factor (LIF) in WE(d/d) uteri. Supplementation with LIF restored decidualization in WE(d/d) mice. Our study indicated that LIF acts synergistically with progesterone to induce the expression of Indian hedgehog (IHH) in uterine epithelium and its receptor patched homolog 1 in the stroma. IHH then induces the expression of chicken ovalbumin upstream promoter-transcription factor II, a transcription factor that promotes stromal differentiation. To address the mechanism by which LIF induces IHH expression, we used mice lacking uterine epithelial signal transducer and activator of transcription 3, a well-known mediator of LIF signaling. Our study revealed that LIF-mediated induction of IHH occurs without the activation of epithelial signal transducer and activator of transcription 3 but uses an alternate pathway involving the activation of the ERK1/2 kinase. Collectively our results provide unique insights into the paracrine mechanisms by which ESR1 directs epithelial-stromal dialogue during pregnancy establishment. PMID:26241389

    Dlx5 and Dlx6 are two closely associated homeobox genes which code for transcription factors involved in the control of steroidogenesis and reproduction. Inactivation of Dlx5/6 in the mouse results in a Leydig cell defect in the male and in ovarian insufficiency in the female. DLX5/6 are also strongly expressed by the human endometrium but their function in the uterus is unknown. The involvement of DLX5/6 in human uterine pathology is suggested by their strong downregulation in endometriotic lesions and upregulation in endometrioïd adenocarcinomas. We first show that Dlx5/6 expression begins in Müllerian ducts epithelia and persists then in the uterine luminal and glandular epithelia throughout post-natal maturation and in the adult. We then use a new mouse model in which Dlx5 and Dlx6 can be simultaneously inactivated in the endometrium using a Pgr(cre/+) allele. Post-natal inactivation of Dlx5/6 in the uterus results in sterility without any obvious ovarian involvement. The uteri of Pgr(cre/+); Dlx5/6(flox/flox) mice present very few uterine glands and numerous abnormally large and branched invaginations of the uterine lumen. In Dlx5/6 mutant uteri, the expression of genes involved in gland formation (Foxa2) and in epithelial remodelling during implantation (Msx1) is significantly reduced. Furthermore, we show that DLX5 is highly expressed in human endometrial glandular epithelium and that its expression is affected in endometriosis. We conclude that Dlx5 and Dlx6 expression determines uterine architecture and adenogenesis and is needed for implantation. Given their importance for female reproduction, DLX5 and DLX6 must be regarded as interesting targets for future clinical research. PMID:26512061

    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.

    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.

    Full Text Available Secondary ovarian tumors compose 3-8% of all, and 10-30% of malignant ovarian tumors. Histopathological features of SOT diagnosed in our department in 10-year period are discussed. Macroscopical, microscopical, immunohistochemical and cytopathological features of secondary ovarian tumors diagnosed between 1997- 2006 were re-evaluated. Additional histochemical and immunohistochemical studies were applied to find the primaries. Data was statistically evaluated. Totally, 44 secondary ovarian tumors had been diagnosed within this period. The mean age of the patients was 52.9 years; the mean tumor diameter was 103.7 mm.The primary was gastrointestinal system in 50% of the cases. Ten of them (22.7% were metastases of signet ring cell carcinoma of stomach (Kruckenberg tumor while 9 cases (20.5% were from colorectal and three (6.8% were from appendiceal adenocarcinomas. 27.3% of our cases were originated from genital tract. Synchronous endometrioid adenocarcinomas of corpus uteri and ovary were seen in six cases (13.6%. Ovarian involvement of serous carcinomas of corpus uteri was seen in five (11.4% cases. Ovarian metastases of breast carcinoma in four cases (9.1% were seen while the ovarian involvement of adrenal cortical and tubal carcinomas was observed in one case, each. The primary was peritoneal surface in five (11.4% of the cases. Tumors were bilateral in 65.9% of the cases, and there was statistically significant correlation between the bilaterality rate of the tumors and the primary (p=0.015.The more precise diagnosis of secondary ovarian tumors could be reached by evaluation of clinical, surgical, macroscopical, microscopical, cytopathological and immunohistochemical findings together.

    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.

  11. 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 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.

    Full Text Available OBJECTIVES: Genistein is known to influence reproductive system development through its binding affinity for estrogen receptors. The present study aimed to further explore the effect of Genistein on the development of the reproductive system of experimental rats. METHODS: Eighteen post-weaning female Sprague Dawley rats were divided into the following groups: (i a control group that received vehicle (distilled water and Tween 80; (ii a group treated with 10 mg/kg body weight (BW of Genistein (Gen 10; and (iii a group treated with a higher dose of Genistein (Gen 100. The rats were treated daily for three weeks from postnatal day 22 (P22 to P42. After the animals were sacrificed, blood samples were collected, and the uteri and ovaries were harvested and subjected to light microscopy and immunohistochemical study. RESULTS: A reduction of the mean weekly BW gain and organ weights (uteri and ovaries were observed in the Gen 10 group compared to the control group; these findings were reversed in the Gen 100 group. Follicle stimulating hormone and estrogen levels were increased in the Gen 10 group and reduced in the Gen 100 group. Luteinizing hormone was reduced in both groups of Genistein-treated animals, and there was a significant difference between the Gen 10 and control groups (p<0.05. These findings were consistent with increased atretic follicular count, a decreased number of corpus luteum and down-regulation of estrogen receptors-a in the uterine tissues of the Genistein-treated animals compared to the control animals. CONCLUSION: Post-weaning exposure to Genistein could affect the development of the reproductive system of ovarian-intact experimental rats because of its action on the hypothalamic-pituitary-gonadal axis by regulating hormones and estrogen receptors.

    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.

    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.

  16. 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 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.

    Full Text Available Envenomations caused by Loxosceles (brown spider have been reported throughout the world. Clinical signs associated to bites of these spiders involve dermonecrotic lesions and intense local inflammatory response, besides systemic manifestations such as intravascular hemolysis, thrombocytopenia, disseminated intravascular coagulation and acute renal failure. The present study aimed to report and to describe dermonecrotic lesions probably caused by a Loxosceles envenomation in a four year-old poodle female dog, treated at the Dermatology Service of the Veterinary Hospital of the Veterinary Medicine and Animal Husbandry School, São Paulo State University, Botucatu, Brazil. Initially, the animal presented two skin lesions with blackish aspect that evolved into ulcerative crusts. The owner reported the presence of a brown spider near the place where the animal spent most of the time. Histological examination of lesions revealed necrosis of the epidermis extending to adnexa and panniculi, which is compatible with Loxosceles bite reaction. The animal was treated with systemic antibiotic and local curatives. Lesions healed by second intention in two months.

    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.

  1. 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

    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.

    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.

  4. 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.

  5. Review: Clinical aspects of hereditary DNA Mismatch repair gene mutations.

    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

    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

    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.

    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.

    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

    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.

    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 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.

    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

    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.

    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.

    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.

    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

    With patients' general situation, medication use, occurrence time of adverse drug reaction/event (ADR/ADE), clinical manifestations and prognosis as reference items, a retrospective study was made for 315 cases with ADR/ADE induced by Gastrodin in Chongqing from January 2008 to June 2014, in order to analyze the characteristics of ADR/ADE and provide reference for rational clinical medication. The results showed that among the 315 cases with ADR/ADE, 143 cases (45.4%) were males and 172 cases (54.6%) were females, most of them (74.9%) were aged above 45; 60 cases (19.0%) with ADE were caused by off-label indications and 66 cases (21.0%) with ADE were caused by over dosage; ADR/ADE cases induced by intravenous drip mainly happened within 30 min (85.5%), ADR/ADE cases induced by oral administration mainly happened within 2 h (74.4%), and all of ADR/ ADE cases induced by intramuscular injection happened within 10 min. Totally 593 ADR/ADE cases were reported, which were mainly damages in gastrointestinal system, skin and its adnexa; And 61.9% of ADR/ADE cases were newly reported. It is suggested that medical workers shall learn about the regularity and characteristics of ADR/ADE induced by gastrodin, apply it in clinic with standards, pay close attention to changes of patients' situations and attach importance to the monitoring of ADR/ADE, so as to enhance the safety of medication.

    The analysis of the results of the preventive medical examination at the uranium production has been conducted by order of Ministry of Health of Kazakhstan, number 243 from 2004.03.12. 352 people have been surveyed, including 36 women, 69 people have been revealed with the pathology, 293 are healthy. Distribution by length of service up to 5 years - 93,5%, up to 8 years: 3 men (6,5%), aged on average 38,9 years. 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.

  4. 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.

    Zootherapeutic practices in ethnoveterinary medicine are important in many socio-cultural environments around the world, particularly in developing countries, and they have recently started to be inventoried and studied in Europe. In light of this, the purpose of this review is to describe the local knowledge and folk remedies based on the use of invertebrates and their derivative products in contemporary Spanish ethnoveterinary medicine. An overview in the fields of ethnozoology, ethnoveterinary medicine and folklore was made. Automated searches in the most important databases were performed. All related works were examined thoroughly and use-reports were obtained from 53 documentary sources. The traditional use of 18 invertebrate species and five ethnotaxa and a total of 86 empirical remedies based on the use of a single species was recorded. The two most relevant zoological groups were found to be insects and molluscs. A broad diversity of body parts or derivative products have been and are used to treat or prevent ca. 50 animal diseases or conditions, in particular diseases of the skin and subcutaneous tissue, different infectious livestock diseases, and disorders of the eye and adnexa. Cattle, sheep and equines form the group of domestic animals in which the greatest number of remedies are mentioned. In addition, seven magical remedies and practices are documented. In comparison with other culturally related areas, this is a rich heritage. The use-reports included here will help in the search for new and low-cost drugs for treating livestock and alternative materials for pharmaceutical purposes, future research addressing the validation of the effects and the development of organic farming.

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 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.

    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.

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

    Full Text Available Background/Aim. Lumbar syphatectomy (LS increases pheripheral blood flow primarily by the arteriolar vasodilatation within the skin vascular net. Increase in tissue nutrition takes place only in the distal blood vessels of the skin. Nevertheless, in some patients sympathectomy brings about improvement in ischemic ulcerations healing. Hyperbaric oxigenation (HBO is a medical treatment in which a patient breathes 100% oxygen under pressure higher than atmospheric implemented in special units allowing the whole body be in a chamber. The aim of the study was to determine efficacy of the applied therapies for the treatment of inoperable occlusive lower extremities (LE arteries diseases according to the obtained results. Methods. The study included 30 patients divided into two groups (15 patients each in which stenosis level of the lower extremities arteries had been determined using aortography due to further treatment with HBO and LS. All the patients were clinically examined, their objective condition evaluation based on claudication distance, pain in rest, skin and skin adnexa atrophy, and temperature and LE functionality, as well as exposed to perfusion scintigraphy prior to the treatment and within 30 days after the treatment finishing. Results. Analyzing patients' status prior to and after the treatments applied the number of patients with obvious improvement was higher in those treated by HBO than those treated by LS. Measuring claudication distance revealed significantly greater changes in patients treated by HBO (from 178.57 m to 754.76 m than in those treated by LS (from 229 m to 253 m. Other clinical symptoms, such as parasthesia, status of the skin adnexes (hair, nails, skin colour and temperature were also improved after the treatment by HBO. Conclusion. The results obatined in this study confirm the advantages of HBO over LS in therapy of inoperable occlusive LE disease, so LS could be definitely abandoned as a choice for treating such

    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.

    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.

    Aim The purpose of this study was to investigate the protective effect of honokiol on experimental ischemia/reperfusion injury of rat ovary. Materials and methods A total of 40 female Wistar albino rats were used in this study. The rats were divided into five groups as follows: sham (Group I), torsion (Group II), torsion + detorsion (Group III), torsion + detorsion + saline (Group IV), and torsion + detorsion + honokiol (Group V). Bilateral adnexa in all the rats except for those in the sham group were exposed to torsion for 3 hours. The rats in Group IV were administered saline, whereas the rats in Group V were administered honokiol by intraperitoneal route 30 minutes before detorsion. Tissue and plasma concentrations of malondialdehyde and nitric oxide were determined. Ovarian tissue was histologically evaluated. Data analyses were performed by means of Kruskal–Wallis test and Mann–Whitney U-test (Bonferroni correction) in SPSS 15.0 (Statistical Package for Social Sciences; SPSS Inc., Chicago, IL, USA). Results The torsion and detorsion groups had higher scores in vascular congestion, hemorrhage, and inflammatory cell infiltration compared with the sham group (P<0.005). In addition, total histopathological scores were significantly higher in the torsion and detorsion groups compared with the sham group (P<0.005). A significant reduction was observed in hemorrhage, inflammatory cell infiltration, and cellular degeneration scores, of all histopathological scores, in the honokiol group (P<0.005). Ovarian tissue concentrations of malondialdehyde were significantly higher in the torsion and detorsion groups compared with the sham and honokiol groups (P<0.005). Ovarian tissue concentrations of nitric oxide, on the other hand, were significantly higher in the torsion group compared with the sham, saline, and honokiol groups (P<0.005). Conclusion Honokiol has a beneficial effect on ovarian torsion-related ischemia/reperfusion injury. PMID:27022246

  14. 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)

    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

    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.

    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

  19. 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 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.

    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.

    Zootherapeutic practices in ethnoveterinary medicine are important in many socio-cultural environments around the world, particularly in developing countries, and they have recently started to be inventoried and studied in Europe. In light of this, the purpose of this review is to describe the local knowledge and folk remedies based on the use of invertebrates and their derivative products in contemporary Spanish ethnoveterinary medicine. An overview in the fields of ethnozoology, ethnoveterinary medicine and folklore was made. Automated searches in the most important databases were performed. All related works were examined thoroughly and use-reports were obtained from 53 documentary sources. The traditional use of 18 invertebrate species and five ethnotaxa and a total of 86 empirical remedies based on the use of a single species was recorded. The two most relevant zoological groups were found to be insects and molluscs. A broad diversity of body parts or derivative products have been and are used to treat or prevent ca. 50 animal diseases or conditions, in particular diseases of the skin and subcutaneous tissue, different infectious livestock diseases, and disorders of the eye and adnexa. Cattle, sheep and equines form the group of domestic animals in which the greatest number of remedies are mentioned. In addition, seven magical remedies and practices are documented.

    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

    目的 测算各种恶性肿瘤的分病程残疾权重和平均残疾权重,为山东省恶性肿瘤疾病负担研究及肿瘤防治对策制定提供参考依据.方法 在山东省2007年恶性肿瘤现患调查中对所有恶性肿瘤患者的健康状况进行调查,参考全球疾病负担研究的方法 ,利用六级社会功能分级标准对患者残疾状况进行分级和赋值,分别计算20种恶性肿瘤的分病程残疾权重和平均残疾权重及其95%CI.结果 共调查恶性肿瘤患者11757例,所有恶性肿瘤治疗期、恢复期、转移期和晚期的残疾权重分别为0.310、0.218、0.450和0.653,平均残疾权重为0.317(95%CI:0.312~0.321).不同恶性肿瘤和不同病程阶段的残疾权重差别显著,性别间差异无统计学意义.肝癌、骨癌、淋巴瘤和胰腺癌平均残疾权重较高(>0.4),乳腺癌、子宫体癌、子宫颈癌、卵巢癌、喉癌和口咽部癌症相对较低(0.4) for liver cancer, bone cancer, lymphoma and pancreas cancer. Lower DWs (<0.3) were found for breast cancer, cervix uteri, corpus uteri, ovarian cancer, larynx cancer, mouth and oropharynx cancer. Conclusion Stage-specific and average DWs for various cancers were estimated based on a large sample size survey. The average DWs of 0.317 for all cancers indicated that 1/3 healthy year lost for each survived life year of them. The difference of DWs between different cancer and stage provide scientific evidence for cancer prevention strategy development.

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

    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

    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

  9. 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.

  10. 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.)

  11. 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.

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.

    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.

    Estrogens exert beneficial effects in the bone. Their chronic use however bares several risks. Therefore intensive search for non-estrogenic, bone protective compounds is going on. We observed that an extract of Tinospora cordifolia has antiosteoporotic effects and identified 20-OH-Ecdysone (beta-Ecdysone=Ecd) as a possible candidate for this action. Ovariectomized (ovx) rats were treated orally over 3 months with no Ecd (control) or 18, 57 or 121 mg Ecd/day/animal. Estradiol-17beta benzoate (E2) 159 microg/day/animal) fed animals served as positive controls. Bone mineral density (BMD) of tibia was measured by quantitative computer tomography, serum Osteocalcin and CrossLaps were measured in a ligand binding assay. Utilizing an estrogen receptor (ER) containing cytosolic extract of porcine uteri the capability of Ecd to bind to ER was tested. Ecd did not bind to ER. BMD was reduced by more than 50% in the control. In the Ecd animals BMD was dose dependently higher. Serum CrossLaps was lower in the Ecd and E2 group while serum Osteocalcin levels were decreased in the E2 but increased in the Ecd fed animals. Ecd has an antiosteoporotic effect which does not involve activation of ER.

    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.

    2015-12-01

    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

    Full Text Available Oestrogenic effects of macerated aqueous extracts of the leaves of Holarrhena fl oribunda (G. Don Dur & Schinz on ovariectomized rat. 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

    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.

  2. 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.

    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.)

    The authors conducted a case-control study designed to evaluate the association between radiotherapy for a first primary cancer and subsequent leukemia risk. Study subjects were selected from four tumor registries (California, Connecticut, Kansas, and Massachusetts). Cases were subjects with two primary concers; the second cancer was a leukemia diagnosed one year or more after the diagnosis of the first primary cancer. Control subjects were patients with single cancers. Two control subjects were chosen for each case matched for tumor registry, site of the first primary cancer, date of diagnosis of the first primary cancer, age, sex, and duration of survival after the first primary cancer. Separate analyses were carried out for chronic lymphatic leukemia (166 cases) and all other leukemias (232 cases). The relative risk of chronic lymphatic leukemia after radiotherapy was 0.7 and did not differ significantly from unity. For all other leukemias, relative risks were 1.6 after radiotherapy for first primary cancers of all sites, 2.4 after radiotherapy to trunk sites, 2.2 after radiotherapy for breast cancer, and 10.3 after radiotherapy for cancer of the corpus uteri. These relative risks for leukemias other than chronic lymphatic leukemia all differed significantly from unity.

    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

    Amniotic fluid cells (AFCs) have been proposed as a valuable source for tissue engineering and regenerative medicine. However, before clinical implementation, rigorous evaluation of this cell source in clinically relevant animal models accepted by regulatory authorities is indispensable. Today, the ovine model represents one of the most accepted preclinical animal models, in particular for cardiovascular applications. Here, we investigate the isolation and use of autologous ovine AFCs as cell source for cardiovascular tissue engineering applications. Fetal fluids were aspirated in vivo from pregnant ewes (n = 9) and from explanted uteri post mortem at different gestational ages (n = 91). Amniotic non-allantoic fluid nature was evaluated biochemically and in vivo samples were compared with post mortem reference samples. Isolated cells revealed an immunohistochemical phenotype similar to ovine bone marrow-derived mesenchymal stem cells (MSCs) and showed expression of stem cell factors described for embryonic stem cells, such as NANOG and STAT-3. Isolated ovine amniotic fluid-derived MSCs were screened for numeric chromosomal aberrations and successfully differentiated into several mesodermal phenotypes. Myofibroblastic ovine AFC lineages were then successfully used for the in vitro fabrication of small- and large-diameter tissue-engineered vascular grafts (n = 10) and cardiovascular patches (n = 34), laying the foundation for the use of this relevant pre-clinical in vivo assessment model for future amniotic fluid cell-based therapeutic applications.

    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.

    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

    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.

    Six hundred and nine cases of invasive squamous cell carcinoma of the cervix uteri in a retrospective analysis (1953-1982) at the A.C. Camargo Hospital, Antonio Prudente Foundation, Sao Paulo, Brazil. The patients were submitted to radical surgery and radiation therapy, individually or in combination. A multivariate analysis of the different variables were performed according to the Cox`s regression method. The variables of prognosis value, in decreasing order of importance, were: the decade of patient`s admission, the modality of therapy employed, the presence of residual tumor in the surgical specimens and the clinical stage of the disease. Other variables like ethnic group, age of first menstrual flux, menopause, number of pregnancy, kind of delivery, number and kind of abortion, were found to be of no prognostic importance. The decade of admission was of independent prognostic significance. The presence of residual tumor in the surgical specimens was more important than lymph nodes spreading, but the overall survival was affected by the increase in the number of positive lymph nodes. Patient`s age was a weak prognostic factor accounting for a reduction in the survival time among cases with age upper to 45 years old. Radiation therapy sterilizes a considerable number of lymph nodes but not all of them in every patient. There are a specific group of patients where the radical surgery is necessary in order to carry a complete debulking of the disease. (author) 82 refs., 10 figs.

  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.

    The co-effect of Cordyceps sinensi (CS; caterpillar fungus) and strontium on ovariectomized osteopenic rats was studied in this paper. After the rats were treated orally with CS, strontium (SR), and CS rich in strontium (CSS), respectively, the urine calcium, plasma calcium, plasma phosphorus, bone mineral content, mechanical testing, and the mass of uterus, thymus, and body were examined. Both CSS and SR have a positive effect on mechanical strength and mineral content of ovariectomized osteopenic rats. However, femoral neck strength in the CSS-treated group was higher than those in the SR-treated groups. CSS and SR significantly decreased urinary calcium excretion and plasma total calcium and inorganic phosphate concentrations. On the contrary, CS and CSS significantly increased weights of atrophic uteri and weights of body and also decreased the thymus mass in animals, whereas SR did not exhibit any such effects. Our experiments have demonstrated that CSS possess a preferable effect against the decrease of bone strength and bone mineral mass caused by osteoporosis. It was caused by the co-effect of CS and strontium. The mechanism of it includes decreases bone resorption, increases bone formation, increases in body weight, and enhances 17β-estradiol-producing as well as enhancing the immune functions in animals. The data provide an important proof of concept that CSS might be a new potential therapy for the management of postmenopausal osteoporosis in humans.

    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.

  19. Embryonic diapause is conserved across mammals.

    Directory of Open Access Journals (Sweden)

    Grazyna E Ptak

    Full Text Available Embryonic diapause (ED is a temporary arrest of embryo development and is characterized by delayed implantation in the uterus. ED occurs in blastocysts of less than 2% of mammalian species, including the mouse (Mus musculus. If ED were an evolutionarily conserved phenomenon, then it should be inducible in blastocysts of normally non-diapausing mammals, such as domestic species. To prove this hypothesis, we examined whether blastocysts from domestic sheep (Ovis aries could enter into diapause following their transfer into mouse uteri in which diapause conditions were induced. Sheep blastocysts entered into diapause, as demonstrated by growth arrest, viability maintenance and their ED-specific pattern of gene expression. Seven days after transfer, diapausing ovine blastocysts were able to resume growth in vitro and, after transfer to surrogate ewe recipients, to develop into normal lambs. The finding that non-diapausing ovine embryos can enter into diapause implies that this phenomenon is phylogenetically conserved and not secondarily acquired by embryos of diapausing species. Our study questions the current model of independent evolution of ED in different mammalian orders.

    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.

    Thirty adult male nodule carriers from a hyperendemic onchocerciasis area in the Liberian rain forest were treated with high doses of diethylcarbamazine (30 mg/kg/d) over one week. Another ten patients received placebo tablets and served as a control. All detectable nodules were removed from half of the patients at two months and from the remaining patients at ten months after chemotherapy. The adult worms in the nodules were examined for pathological alterations by the collagenase technique including embryogram, and by histology. No macrofilaricidal effect was observed at either time, and no significant reduction of microfilariae in the uteri of the female worms or in the tissue of the nodules was seen. Two months after the therapy there was a significant increase of degenerated stretched intrauterine microfilariae but this effect was no longer observed after ten months. No pathological effect was seen on the intrauterine coiled microfilariae. On the contrary, their number had significantly increased after ten months which could mean a stimulation of the embryogenesis. No effect on spermatogenesis was observed. Both techniques, the collagenase digestion and the histological examination of the nodules, provided similar results to demonstrate that there was no marked long lasting effect on O. volvulus after a treatment with high doses of diethylcarbamazine.

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

    A reliable application of the polymerase chain reaction (PCR) for detection of the human papilloma virus (HPV) genotypes in cervical smears and biopsies was developed. Primers flanking the HPV cloning site were used to avoid detection of cloned HPV plasmids. These anticontamination primers were used for the specific detection of HPV 6, 11, 16, 18, and 33 in cervical scrapes that had been tested previously for HPV with a combined modified filter in situ hybridization (modified FISH) and dot blotting procedure. The PCR appeared to be superior. Two groups of women were screened for HPV genotypes. Group A consisted of women belonging to a regularly screened population, and group B contained women attending a gynaecological clinic. It appeared that the overall prevalence of HPV in cytologically normal scrapes in the first group was 6%, whereas in the second group 12% was found. In scrapes with cytological dysplasia, the prevalence of HPV in group A and B was approximately 40% and 60%, respectively. HPV 16 was present predominantly. In biopsies of squamous cell carcinomas of the cervix uteri, an HPV prevalence rate of 90% was found, all of which contained only HPV 16 and 18. These data indicate an important role for HPV detection in the screening of cervical scrapes to identify women with an increased risk of cervical cancer. PMID:2555442

    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.

    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.

    Serpentirhabdias atracti n. sp. is described based on specimens discovered in the lung of Atractus major Boulenger from Caxiuanã National Forest, Pará, Brazil. The new species is assigned to Serpentirhabdias Tkach, Kuzmin & Snyder, 2014 based on morphological characters (comparatively thin body cuticle without prominent inflations, arrangement of circumoral papillae in two lateral groups, pre-equatorial position of vulva, eggs in uteri at early cleavage stages), as well as because of its parasitism in snakes. The new species is most similar to S. vellardi (Pereira, 1928) due to the absence of lips and buccal capsule, similar body dimensions, and the specificity to dipsadid snakes in Brazil. The two species differ in the shape of the tail (bulbous dilatation in the posterior part followed by a thread-like tail tip present in S. atracti n. sp.), the width of the oesophagus, and the size of the excretory glands. Serpentirhabdias atracti n. sp. is the sixth species of this genus found in the Neotropical Region.

    Heavy distillate (HD), the highest-boiling coal liquid from the solvent-refined coal-II process (SRC-II), was administered by intragastric (IG) intubation to pregnant rats. Five dose levels of HD (0.09, 0.14, 0.18, 0.36 and 0.74 g kg/sup -1/), were given daily from 12 to 16 days of gestation and the rats were killed at 20 days of gestation. Maternal body weights and weights of the liver, kidneys, spleen, adrenals, thymus, ovaries and the gravid uterus were obtained. Gravid uteri were evaluated for prenatal mortality. Live fetuses were examined for malformations and weighed; fetal lungs were excised and weighed. Maternal (extragestational) weight gains and thymic weights diminished in all groups that received the SRC material. Adrenal weights were increased in all treated animals, except for those in the lowest-dose group (0.9 g kg/sup -1/). There was significant maternal mortality at 0.74 g kg/sup -1/ and increased intrauterine mortality at doses of 0.37 and 0.74 g kg/sup -1/. Placental weight was depressed, and the incidence of fetal anomalies was increased at 0.14 g kg/sup -1/ and all higher dose levels. 19 references, 1 figure, 5 tables.

    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

    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.

    Full Text Available Introduction. Gestational trophoblastic neoplasm (GTN, choriocarcinoma in coexistence with primary cervical adenocarcinoma, is a rare event not easy to diagnose. Choriocarcinoma is a malignant form of GTN but curable if metastases do not appear early and spread fast. Case report. We presented choriocarcinoma in coexistence with primary cervical adenocarcinoma in a 48-year-old patient who had radical hysterectomy because of confirmed cervical carcinoma (Dg: Carcinoma porto vaginalis uteri FIGO st I B1. Histological findings confirmed cervical choriocarcinoma with extensive vascular invasion and apoptosis but GTN choriocarcinoma was finally confirmed after immunohystochemical examinations. Preoperative serum human gonadotropine (beta hCG level stayed unknown. This patient did not have any pregnancy-like symptoms before the operation. The first beta hCG monitoring was done two months after the operation and found negative. According to the final diagnosis the decision of Consilium for Malignant Diseases was that this patient needed serum hCG monitoring as well as treatment with chemotherapy for high-risk GTN and consequent irradiation for adenocarcinoma. Conclusion. The early and proper diagnosis of nonmetastatic choriocarcinoma of nongestational origine in coexistence with cervical carcinoma is curable and can have good prognosis.

    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.

  14. 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.

    The aim of this study was to investigate the spatiotemporal expression and regulation of GRP78 in the mouse uterus during the peri-implantation period. The GRP78 protein was mainly detected in the luminal and glandular epithelia on days 1-4 of pregnancy. On day 5 of pregnancy, the GRP78 protein was more highly observed around the implanted embryo at the implantation site. There was no detectable GRP78 protein signal on day 5 of pseudopregnancy. GRP78 mRNA and protein levels gradually increased on days 6-8 of pregnancy, and the expression pattern was also expanded, coinciding with the development of decidua. Similarly, GRP78 expression was also strongly expressed in decidualised cells following artificial decidualisation. Compared with the results obtained with the delayed uterus, a high level of GRP78 expression was detected in the implantation-activated uterus. In the uteri of ovariectomised mice, GRP78 expression increased and reached its highest level after injection of oestrogen, and progesterone seemed to have an antagonistic effect on oestrogen up-regulation of GRP78 expression. Our data indicate that GRP78 might play an important role during the process of mouse embryo implantation, and GRP78 expression was mainly regulated by active blastocysts and maternal oestrogen.

    Full Text Available The implantation process is complex, requiring reciprocal interactions between implantation-competent blastocysts and the receptive uterus. There were reports to show that some microRNAs (miRNAs may play a key role during embryo implantation in mouse. However, the miR-320 expression profiles in the rat uterus during peri-implantation are unknown. In the present study, we found that the expression level of miR-320 was lower on day 5 of gestation (g.d. 5 in rats than g.d.3 and g.d.4 and restored gradually from g.d.6. MiR-320 was specifically localized in glandular and luminal epithelia and decidua. The expression of miR-320 was not significantly different in the pseudopregnant uterus and decreased in the uteri of rats subjected to activation of delayed implantation. Artificial decidualization and treatment with progesterone increased the miR-320 expression. Thus, miR-320 was differentially expressed in the rat uterus during implantation. The expression level was affected by active blastocysts and decidualization during the window of implantation. Steroid hormones, progesterone stimulated miR-320 expression.

    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

    Objective: To determine the effects of ethanolic leaf extract of Spondias mombin (S. mombin) on the histology of the anterior pituitary, ovary and uterus; and on the serum sex hormones of adult female Wistar rats. Methods: Twenty-four female Wistar rats were randomly assigned into four groups of six rats per group. The animals in the treatment groups were administered orally ethanolic extract of S. mombin leaves at the doses of 250, 350 and 500 mg/kg body weight daily for fourteen days. Rats in the control group received distilled water. The body weights of the rats were determined at the beginning and end of the experiment. Histological analysis of pituitary, ovary and uterus was carried out. Hormonal assay for estrogen, progesterone, FSH and LH were done using Enzyme-Linked Immunoabsorbent Assay (ELISA). Results: There was significant (P<0.05) decrease in relative organ weights of extract-treated rats compared to the control. Pituitary showed accumulation and aggregation of cells in experimental animals. Uteri of treated groups showed thickening of endometrial lining and presence of cysts, ovarian tissues were damaged. Furthermore, the extract caused reduction in serum concentration of sex hormones of the treated animals relative to the control. Conclusion: This study suggests that ethanolic extract of S. mombin leaf may have antifertility property, confirming its use as a local contraceptive.

    Primary retroperitoneal Müllerian adenocarcinoma (PRMA) is an extremely rare tumor and the cause remains unknown. We report a case of PRMA arising from endometriosis. A 52-year-old woman with a history of malignant lymphoma underwent a follow-up computed tomography scan, which revealed a retroperitoneal tumor. Immunohistochemical analysis of tumor resected during laparoscopic surgery showed adenocarcinoma positive for cytokeratin 7 and negative for cytokeratin 20. The patient had undergone hysterectomy and bilateral salpingo-oophorectomy 14 years ago for myoma uteri and endometrial cysts and was treated with estrogen-replacement therapy. The size of the tumor increased and laparotomy was performed. Histopathological examination showed adenocarcinoma resembling endometrial adenocarcinoma, which stained positive for cancer antigen 125, cancer antigen 19-9, estrogen receptor, and progesterone receptor immunohistochemically. The focus of the endometriosis was found at the edge of the tumor, and the stromal cells around the tumor cells were CD10 positive. The patient was diagnosed as having PRMA arising from endometriosis, and treated with adjuvant chemotherapy.

    The present study examines anatomical and histological characteristics of tubular genital organs and its relationships with the reproductive state of 24 wild adult collared peccary (Tayassu tajacu) females. The tunica mucosa of the uterine tube presents a pseudostratified, intermittently ciliated columnar epithelium. The epithelial secretory cells of pregnant females and females in the luteal phase of the oestrous cycle became taller than the ciliated cells and showed abundant apical secretory blebs, whereas secretory cells of females in the follicular phase showed abundant mucous secretory activity (periodic acid-Schiff positive cells). The uterus is composed of two narrow and convoluted uterine horns, separated by the velum uteri, a small uterine body and a long and muscular cervix. The endometrial lining of both uterine horns and body is a monostratified, columnar ciliated epithelium. Pregnant females and females in luteal phase showed a more developed hyperplasia of the endometrial simple tubular glands than females in the follicular phase. The cervix presents interdigitated rows of mucosal prominences that project into the lumen, structures similar to pulvini cervicali, occluding the cervical canal. In pregnant females, the endocervical canal was filled by a viscous cervical secretion. Females in follicular phase presented a thicker vaginal epithelium than pregnant females and females in luteal phase. The present study suggests that the collared peccary female showed different histological features of the uterine tubes, uterus and vagina in accordance with the reproductive state of the females.

    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

    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

    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.

    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.

    Mammalian parthenogenetic embryos invariably die in mid-gestation from imprinted gene defects and placental hypoplasia. Based on chimera experiments, trophoblastic proliferation is supposed to be inhibited in the absence of a male genome. Here, we show that parthenogenetic mouse embryonic cell nuclei can be reprogrammed by serial rounds of nuclear transfer without using any genetic modification. The durations of survival in uteri of cloned foetuses derived from green fluorescent protein (GFP)-labelled parthenogenetic cell nuclei were extended with repeated nuclear transfers. After five repeats, live cloned foetuses were obtained up to day 14.5 of gestation; however, they did not survive longer even when we repeated nuclear transfer up to nine times. All foetuses showed intestinal herniation and possessed well-expanded large placentas. When embryonic stem (ES) cells derived from fertilised embryos were aggregated with the cloned embryos, full-term offspring with large placentas were obtained from the chimeric embryos. Those placentas were derived from parthenogenetic cell nuclei, judging from GFP expression. The patterns of imprinted gene expression and methylation status were similar to their parthenogenetic origin, except for Peg10, which showed the same level as in the normal placenta. These results suggest that there is a limitation for foetal development in the ability to reprogramme imprinted genes by repeated rounds of nuclear transfer. However, the placentas of parthenogenetic embryos can escape epigenetic regulation when developed using nuclear transfer techniques and can support foetal development to full gestation.

    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.

  8. 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.

    30 female patients with the diagnosis of "uterus myomatosus" and a control group of also 30 women with the diagnosis "descensus uteri et vaginae" were examined by a standardized questionnaire containing socio-economic, anamnestic and psychological data. To get information about their personality the "Freiburger Persönlichkeitsinventar" (Freiburg Personality Inventory), half-form A, was administered at the end of the interview. The age limits were 35 and 55 years. The main socio-economic results are the following: during childhood and adolescence the myom-patients lived mainly near towns (p less than 0,01). The women of this group have better relationships to their husbands than the descensus-patients (p less than 0,01) and the husbands of the myom-patients are more often (p less than 0,01) of the same age or younger than their women. 18 out of the 30 women of the myom-group (i.e. more than 50%) said that their wish to become a mother has not been fulfilled while this answer was given by none of the 30 descensus-patients (p less than 0,01). The question is discussed in how far the uterus-myom can be understood as a somatic expression of the frustrated wish to get a child, as a "compensatory growth". Beside this, the authors are aware of the fact that other aspects, f.e. hormonal factors, may be important. PMID:6857159

    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.

    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

  13. Counting human somatic cell replications: methylation mirrors endometrial stem cell divisions.

    Cell proliferation may be altered in many diseases, but it is uncertain exactly how to measure total numbers of divisions. Although it is impossible to count every division directly, potentially total numbers of stem cell divisions since birth may be inferred from numbers of somatic errors. The idea is that divisions are surreptitiously recorded by random errors that occur during replication. To test this "molecular clock" hypothesis, epigenetic errors encoded in certain methylation patterns were counted in glands from 30 uteri. Endometrial divisions can differ among women because of differences in estrogen exposures or numbers of menstrual cycles. Consistent with an association between mitotic age and methylation, there was an age-related increase in methylation with stable levels after menopause, and significantly less methylation was observed in lean or older multiparous women. Methylation patterns were diverse and more consistent with niche rather than immortal stem cell lineages. There was no evidence for decreased stem cell survival with aging. An ability to count lifetime numbers of stem cell divisions covertly recorded by random replication errors provides new opportunities to link cell proliferation with aging and cancer. PMID:16314580

    Nine gilts weighing 80 kg at the beginning of the trial were fed a mycotoxin contaminated diet containing 2 mg deoxynivalenol (DON) and 0.4 mg zearalenone (ZON) per kg (Diet M). Their daily weight gain until 103 kg BW was reduced in comparison to the nine control animals fed an uncontaminated diet (Diet C) (763 vs. 912 g; p = 0.02). There was no treatment effect on the age at first observed oestrus. Seven and eight gilts receiving Diet M and C, respectively, became pregnant after being mated once or being again mated three weeks later. The examination of the uteri of gilts slaughtered 35-61 days after mating showed that the exposure to DON and ZON had no effect on the number of foetuses per gilt (p = 0.54), but increased their growth rate (p = 0.003). Thus, low dietary DON and ZON levels had no negative effects on the reproductive parameters examined. The hypothesis that the bulbourethral gland weight of barrows can be used for the bioassay of low dietary ZON levels was rejected since feeding Diet M from 80-103 kg BW did not increase the weight of that accessory sex gland (p = 0.51).

    Objective To investigate the effect of estridiol and progesterone at different levels on nuclear factor-kappa-B (NF-κB) expression in mouse endometrium Methods Ovarioectmized mice were randomly divided into 9 groups, i.e. groups of sham operation, of estridiol only, of progesterone only and of progesterone combined with estridiol. Mice in the experimental groups accepted subcutaneous injections of estridiol or progesterone at different levels for one week. Their uteri were collected to detect the expression of NF-κB by immunohistochemical assay.Results Estridiol at a daily dose of 30tg/kg and 1 00 μg/kg could significantly stimulate the expression of NF-κB in mouse endometrium(P<0. 01), but not in an obvious dose-dependent fashion (P>0. 05). Progesterone alone could inhibit the expression of NF-κB in cytoplasma (P<0.01). Combination of estridiol and progesterone could increase NF-κB expression both in cytoplasma and nuclear (P<0.01).Conclusion Eestridiol can up-regulate the expression of NF-κB in mouse endometrium,while progesterone exhibits down-regulation effect. This finding suggests that estridiol and progesterone might modulate the endometrium receptivity by affecting NF-κB pathway.

    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

  17. 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

    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.

  19. 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)

    1991-05-01

    A total of 55 puerperants+ with endometritis followed by spontaneous labours (26 females) and cesarean operation (29 females) were studied. A comprehensive study involved echography, hysteroscopy, bacteriological analysis of the uterine content, and histological examination of mucosal curettage of the corpus uteri. Three types of the clinical course of endometritis were identified: 1) in the presence of placental tissue residues; 2) with necrosis of delayed decidual tissue and lochia- or hematometra; and 3) a "pure" type of endometritis without abnormal tissues in the uterus. Uterine curettage was performed in the first type of endometritis, vacuum aspiration of its content was carried out in Type 2. The patients from Group 3 who had the most severe inflammatory process of the uterus underwent its cavity washing with large volumes of cold antiseptic solutions, took detoxifying, ++rheo-vasoactive and protein agents, received immunomodulating and uterotonic therapy. The algorithm developed for management of puerperants+ with postpartum endometritis substantially enhanced the efficiency of therapy and prevented severe septic events in time. PMID:1897670

  1. 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

    Full Text Available The present study evaluates potential hazardous of nickel (Ni+2 as NiCl2·6H2O to Swiss albino mice fetus. Ni was administered orally on body weight base from days 6 to 13 of gestation period. Based on LD50, Ni doses (46.125, 92.25, and 184.5 mg Ni/kg b.wt. were used. On day 18 of gestation, uteri of the sacrificed dams were examined. A dose-dependent decrease ( in the body weight of the pregnant females and fetuses during the gestation period was observed. Number of implant sites and placental weight at all the three dose levels was lower compared with their respective control groups. Average number of live fetuses/dams reduced significantly ( at 184.5 mg Ni/kg b.wt. with concomitant increase in the percentage of postimplantation death and percentage of resorbed, macerated, and dead fetuses, respectively. Exposure increased the fetal malformations, namely, hydrocephaly, open eyelids, microphthalmia, exophthalmia, club foot, umbilical hernia, and skeletal anomalies. Reduced ossification of nasal, frontal, parietal, intraparietal, and supraoccipital bones, absence/gap between the ribs, reduced/fused sternebrae, vertebral centra, and caudal vertebrae, reduced pelvic elements, absence of carpals, metacarpals, tarsals, metatarsals, and phalanges were distinct. This indicates vulnerability of the mice fetus to nickel during prenatal exposure.

  3. 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

    This study examines the expression of the multi-functional cytokine, vascular permeability factor/vascular endothelial growth factor (VPF/VEGF) in the rat uterus during early proestrus, proestrus, estrus and diestrus. Groups of ovariectomized or hypophysectomized rats served as endocrine controls. Expression of VPF/VEGF mRNA was 2-fold greater in uteri during proestrus and estrus than in other phases of the estrous cycle. In situ hybridization techniques indicated that VPF/VEGF mRNA expression was confined to the luminal epithelium during proestrus, but shifted to the stromal compartment during estrus. Ovariectomized, hypophysectomized or diestrus rats exhibited scattered localization of VPF/VEGF mRNA among glandular epithelium and endometrial stromal compartments. Although VPF/VEGF mRNA was expressed throughout the estrous cycle, but in different compartments of the endometrium depending on the stage of the estrous cycle, VPF/VEGF protein expression appears to be restricted to the epithelial compartment during proestrus and estrus. Results indicate that circulating levels of gonadal steroids and LH may be associated with the differential expression of VPF/VEGF mRNA and its translation activity in the endometrium during different stages of the estrous cycle.

  5. 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)

  6. Fertility Preservation for Women with Ovarian Cancer:a Minireview%卵巢恶性肿瘤患者保留生育功能的再思考

    Institute of Scientific and Technical Information of China (English)

    2014-01-01

    伴随全球晚婚和少育倾向越来越严重,卵巢癌的发病率也逐渐增高。临床工作中经常需要面对恶性卵巢肿瘤患者需要保留生育功能问题。目前Ⅰa期交界性卵巢瘤和Ⅰa期高分化型(G1)除外透明细胞癌的恶性上皮性卵巢癌是保留生育功能手术的适应证。手术以切除患侧附件、对侧卵巢活检、腹水细胞学检测和腹膜后[盆腔和(或)腹腔]淋巴结清扫或活检术为基本术式。由于医学伦理学很难对此开展随机对照研究得到结论性数据,造成各个国家或者机构卵巢癌保留生育手术的功能适应证和术式不一致。另一方面随着需要保留生育功能的恶性卵巢肿瘤患者的增加,保留生育功能手术的适应证是否有扩大的可能性值得探讨。%The fertility preservation for those patients with malignant ovarian tumors are often an important problem for clinical doctors, due to more and more late marriage and fewer births, and increasing rate of ovarian cancer. The indications of preserving fertility include Ⅰa borderline ovarian tumor and Ⅰa of G1 malignant epithelial ovarian cancer except for the clear cell carcinoma. Resection of the affected uterine adnexa, and contralateral ovarian biopsy, ascites cytology and peritoneal lymph nodes (pelvic and/or abdominal) dissection or biopsy are basic surgical technique. It is difficult to carry out the randomized controlled study to get conclusive data due to medical ethics. So, there is inconsistency in indications and surgical methods of preserving fertility for those patients with ovarian cancer. On the other hand, with the increasing patients with malignant ovarian tumors, the indication of preserving fertility might be expanded. This paper reviewed these hot issues.

  7. 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

  9. Mucosa-associated lymphoid tissue lymphoma with initial supradiaphragmatic presentation: natural history and patterns of disease progression

    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

    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

    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

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

    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

    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

    To investigate the roles ofEscherichia coli in the pathogenesis of postpartum uterine diseases in dairy cows, a total of 145E. coli isolates were recovered from 18 healthy cows (61 isolates) and 25 cows with clinical endometritis (84 isolates) at 25–35 days after parturition. Genomic characteristics including phylogenetic grouping, genetic diversity and virulence genes of E. coli isolates were screened to proifle the characteristics related to uterine infections. The susceptibility of the bacteria against 23 antibiotics was also evaluated to support prevention and treatment of clinical cases. Genetic diversity ofE. coli identiifed by random ampliifcation of polymorphic DNA (RAPD) revealed 103 clonal types, including 3 common types to unaffected cows and endometritis cows, 39 types speciifc to healthy cows and 61 types in endometritis subjects. In addition, the isolates from endometritis uteri showed more genetic variability compared with that of healthy cows. Ac-cording to the ifndings of phylogenetic grouping, theE. coli isolates were assigned to group A (35.9%), B1 (59.3%) and D (4.8%). The expression of 10 of 20 virulence gens were detected positively, and onlyifmH gene was revealed signiifcantly (P<0.05) associated with endometritis. From antimicrobial susceptibility test,E. coli was found highly resistant to tetracy-cline, ampicilin, carbenicilin and amoxicilin, but sensitive to amikacin, netilmicin, tobramycin, cefepime and ceftazidime. In conclusion,E. coliwere extensively observed in both healthy and endometritis cows, and presented a large clonal types, however, ifmH was the only gene observed associated with clinical endometritis. Our results suggest that the drugs like amikacin, netilmicin, tobramycin and cefepime could be considered for preventing and treating clinical endometritis in the practical management of dairy cow.

    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

    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

    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)

    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

    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)

    The aim of this study was to localize and evaluate the role of Toll-like receptor 2 (TLR2) in the endometrium and cervix of bitches at different stages of the oestrous cycle and in bitches with pyometra. Sixty-seven nulliparous dogs, ranging in age from 1 to 13 years, were allocated amongst five groups (pro-oestrus; n = 7, oestrus; n = 10, dioestrus; n = 16, anoestrus; n = 11, pyometra; n = 23). Blood samples were collected for the measurement of progesterone concentration. The mean progesterone concentration was analysed as a parameter for validating the stage of the oestrous cycle in bitches. Tissues collected from uterine horn and cervix were fixed in 4% paraformaldehyde for immunohistochemical examination of TLR2. The expression of TLR2 was assessed semi-quantitatively. No pathological changes were found in the uterine samples of healthy dogs. In bitches with pyometra, the glandular epithelium expressed TLR2 more intensely than the surface epithelium. The expression of TLR2 in the glandular epithelium was also significantly higher in healthy dogs at oestrus, dioestrus and dogs with pyometra compared with anoestrous dogs (p dogs at all stages. The surface epithelium of cervix in dogs with pyometra expressed TLR2 significantly more intensely than did the stoma, whereas the expression of TLR2 during oestrus and dioestrus was absent in the stroma of cervix. This study provides the first report of immunohistochemical localization of TLR2 in the canine reproductive tract. In the present study, TLR2 was expressed in endometrial epithelium but was absent in the endometrial stroma of healthy dogs at all oestrous cycle stages. These findings suggest differential expression of TLR in endometrial cells. On the other hand, the lack of TLR2 in the stroma of healthy uteri of dogs may predispose to infection from the invading pathogens once the epithelial cells have been destroyed by the pathogens, especially Gram-positive bacteria.

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

    Infertility caused by ovarian or tubal problems can be treated using In Vitro Fertilization and Embryo Transfer (IVF-ET); however, this is not possible for women with uterine loss and malformations that require uterine reconstruction for the treatment of their infertility. In this study, we are the first to report the usefulness of decellularized matrices as a scaffold for uterine reconstruction. Uterine tissues were extracted from Sprague Dawley (SD) rats and decellularized using either sodium dodecyl sulfate (SDS) or high hydrostatic pressure (HHP) at optimized conditions. Histological staining and quantitative analysis showed that both SDS and HHP methods effectively removed cells from the tissues with, specifically, a significant reduction of DNA contents for HHP constructs. HHP constructs highly retained the collagen content, the main component of extracellular matrices in uterine tissue, compared to SDS constructs and had similar content levels of collagen to the native tissue. The mechanical strength of the HHP constructs was similar to that of the native tissue, while that of the SDS constructs was significantly elevated. Transmission electron microscopy (TEM) revealed no apparent denaturation of collagen fibers in the HHP constructs compared to the SDS constructs. Transplantation of the decellularized tissues into rat uteri revealed the successful regeneration of the uterine tissues with a 3-layer structure 30 days after the transplantation. Moreover, a lot of epithelial gland tissue and Ki67 positive cells were detected. Immunohistochemical analyses showed that the regenerated tissues have a normal response to ovarian hormone for pregnancy. The subsequent pregnancy test after 30 days transplantation revealed successful pregnancy for both the SDS and HHP groups. These findings indicate that the decellularized matrix from the uterine tissue can be a potential scaffold for uterine regeneration.

    Full Text Available Context : Most in vitro fertilization (IVF programs employ embryo cryopreservation to enhance pregnancies from a single ovarian stimulation. More embryos are created, some of which are not transferred to the uterus immediately, generating a need for improved cryopreservation protocols. One protocol may involve growing embryos to a further stage of development, allowing only embryos with proven developmental capabilities to be cryopreserved. Here we examined thaw survival, implantation and live birth rates of embryos cryopreserved at different stages. Aims : We examined thaw survival, implantation and live birth rates of embryos cryopreserved at the zygote, day 3 (D3 embryos or blastocyst stage. Settings and Design : This is a retrospective study from a single academic IVF program. Patients and Methods :0 A retrospective study of all patients who had frozen embryos transferred to their uteri from year 2002 to 2008 at a single academic IVF program was conducted. Statistical Analysis Used : Analysis of variance followed by Fisher′s Exact Test was performed to compare the survival after thaw, implantation and live birth rates between the three groups. Results : One thousand nine hundred and ninety-one zygotes, 2880 D3 embryos and 503 blastocysts were frozen using a slow freeze technique, thawed and transferred. Significantly more D3 embryos and blastocysts survived the thawing process compared to zygotes and significantly higher implantation rate per number of thawed blastocysts was achieved than that for zygotes. Live birth rates were similar between the three groups. Conclusions : Growing embryos to blastocyst stage prior to cryopreservation is associated with fewer frozen embryos but does not appear compromise patients′ chance of achieving pregnancy

    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.

  8. Embryonic death, dwarfism and fetal malformations after irradiation of embryos at the zygote stage. Studies on two mouse strains

    Female mice of the BALB/c and CF1 strains were mated and irradiated with various doses of X-rays 7 h after presumed fertilization. 18 days later, females were killed and their uteri examined for prenatal mortality at the different stages of development. Living fetuses were weighed and examined for the presence of external malformations. A number of them were also examined for skeletal anomalies. Radiation induced mainly a dose-dependent increase of the preimplantation loss in the BALB/c strain and of the early postimplantation loss in the CF1 strain. Embryos of the BALB/c strain were refractory to the induction of teratogenic effects after such preimplantation irradiation. In CF1 mice, the frequency of malformed fetuses increased regularly after irradiation, the difference with controls being significant for the doses of 10, 50 and 100 cGy. Dwarfism occurrence also appeared to be increased by irradiation in this strain, although the importance of this effect varied depending on the criterion chosen for the assessment of dwarfs. With the definition proposed in the present paper, the increase in the frequency of dwarfs paralleled that of malformed fetuses, being significant after doses of 50 and 100 cGy. Irradiation did not increase the frequency of skeletal anomalies. A careful examination of the various data obtained to date led us to conclude that radiation may possibly be teratogenic in several mouse strains, when administered as early as during the one-cell stage and, to a lesser extent, during the following preimplantation stages. However, early prenatal mortality will remain by far the greatest risk associated with an exposure to radiation during this period. Moreover, the relativity of the risk of abnormality due to such irradiation should be considered in the context of the high prevalence of developmental defects spontaneously occurring during human pregnancy.

    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.

    To evaluate the evidence of effects and safety of magnesium sulfate on neuroprotection for preterm infants who had exposure in uteri. We searched electronic databases and bibliographies of relevant papers to identify studies comparing magnesium sulfate (MgSO4) with placebo or other treatments in patients at high risk of preterm labor and reporting effects and safety of MgSO4 for antenatal infants. Then, we did this meta-analysis based on PRISMA guideline. The primary outcomes included fatal death, cerebral palsy (CP), intraventricular hemorrhage, and periventricular leukomalacia. Secondary outcomes included various neonatal and maternal outcomes. Ten studies including 6 randomized controlled trials and 5 cohort studies, and involving 18,655 preterm infants were analyzed. For the rate of moderate to severe CP, MgSO4 showed the ability to reduce the risk and achieved statistically significant difference (odd ratio [OR] 0.61, 95% confidence interval [CI] 0.42-0.89, P = 0.01). The comparison of mortality rate between the MgSO4 group and the placebo group only presented small difference clinically, but reached no statistical significance (OR 0.92, 95% CI 0.77-1.11, P = 0.39). Summarily, the analysis of adverse effects on babies showed no margin (P > 0.05). Yet for mothers, MgSO4 exhibited obvious side-effects, such as respiratory depression, nausea and so forth, but there exited great heterogeneity. MgSO4 administered to women at high risk of preterm labor could reduce the risk of moderate to severe CP, without obvious adverse effects on babies. Although there exit many unfavorable effects on mothers, yet they may be lessened through reduction of the dose of MgSO4 and could be tolerable for mothers. So MgSO4 is both beneficial and safety to be used as a neuroprotective agent for premature infants before a valid alternative was discovered. PMID:26735551

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

    Pten is the most frequently mutated gene in uterine endometriod carcinoma (UEC) and its precursor complex atypical hyperplasia (CAH). Because the mutation frequency is similar in CAH and UEC, Pten mutations are thought to occur relatively early in endometrial tumorigenesis. Previous work from our laboratory using the Pten{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.

    The number of long-term cancer survivors in the general population of the UK is substantial and increasing rapidly. Many cancer survivors have been treated with radiotherapy but the likely number of radiotherapy-related second cancers has not previously been estimated. We used estimates of the numbers of cancer survivors in the UK at the beginning of 2007, in conjunction with estimates of the relative risk of a second primary cancer associated with previous radiotherapy from the United States Surveillance Epidemiology and End Results (SEER) programme, to estimate the numbers of incident cancers in the UK in 2007 that were associated with radiotherapy for a previous cancer and that may have been caused by it. We estimated that 1,346 cases of cancer, or about 0.45% of the 298,000 new cancers registered in the UK in 2007, were associated with radiotherapy for a previous cancer. The largest numbers of radiotherapy-related second cancers were lung cancer (23.7% of the total), oesophageal cancer (13.3%), and female breast cancer (10.6%); 54% of radiotherapy-related second cancers were in individuals aged 75 or over. The highest percentages of second cancers related to radiotherapy were among survivors of Hodgkin's disease and cancers of the oral cavity and pharynx and cervix uteri; over 15% of second cancers among these survivors were associated with radiotherapy for the first cancer. These calculations, which involve a number of assumptions and approximations, provide a reasonable, if conservative, estimate of the fraction of incident cancers in the UK that are attributable to past radiation therapy.

    Full Text Available This study assesses the morbidity and complications of treatment among long-term survivors of cervical cancer. Ninety-eight female patients who were diagnosed and treated from invasive carcinoma of the cervix uteri 5 years or more are included in this study. All the cases were free of disease and had survived up to December 2010. Forty-one cases were treated with radical hysterectomy with removal of the lymph nodes (Wertheim’s surgery (42%. Radical radiation therapy was given to 57 cases (58% according to our treatment protocol; weekly cisplatin was given concomitantly with radiation. Although urinary adverse effects were more prevalent among the radiation group, the difference was not statistically significant. Bowel dysfunction was more prevalent and statistically significant (p\\0.001 among the radiotherapy arm. Dysfunctions recorded included change in bowel habit, diarrhea, constipation, tenesmus, soiling of clothes and or flatulence. However, their severity was grade 1–2 only. The frequency of small intestinal obstruction was comparable in both arms. Pelvic vein thromboses had a tendency to occur among the surgical group especially in obese females (p value 0.005. The frequency of sexual dysfunction was comparable in both groups with no statistical difference. It was age related. The younger the patients’ ages, the more was the sexual complaint irrespective to the treatment modality. Sexual problems included dyspareunia from vaginal stenosis shortening or dryness, vulval soreness from itching and dryness. Bearing in mind that many patients had more than one health complaint. The remaining cases denied the presence of any complications and stated that they had a normal life style.

    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

    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

    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

    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

    Normal pregnancy is associated with uterine relaxation to accommodate the stretch imposed by the growing fetus; however, the mechanisms underlying the relationship between pregnancy-associated uterine stretch and uterine relaxation are unclear. We hypothesized that increased uterine stretch during pregnancy is associated with upregulation of matrix metalloproteinases (MMPs), which in turn cause inhibition of myometrium contraction and promote uterine relaxation. Uteri from virgin, midpregnant (day 12), and late-pregnant rats (day 19) were isolated, and myometrium strips were prepared for measurement of isometric contraction and MMP expression and activity using RT-PCR, Western blot analysis, and gelatin zymography. Oxytocin caused concentration-dependent contraction of myometrium strips that was reduced in mid- and late-pregnant rats compared with virgin rats. Pretreatment with the MMP inhibitors SB-3CT (MMP-2/MMP-9 Inhibitor IV), BB-94 (batimastat), or Ro-28-2653 (cipemastat) enhanced contraction in myometrium of pregnant rats. RT-PCR, Western blot analysis, and gelatin zymography demonstrated increased mRNA expression, protein amount, and activity of MMP-2 and MMP-9 in myometrium of late-pregnant>midpregnant>virgin rats. Prolonged stretch of myometrium strips of virgin rats under 8 g basal tension for 18 h was associated with reduced contraction and enhanced expression and activity of MMP-2 and MMP-9, which were reversed by MMP inhibitors. Concomitant treatment of stretched myometrium of virgin rats with 17β-estradiol (E2), progesterone (P4), or E2+P4 was associated with further reduction in contraction and increased MMP expression and activity. MMP-2 and MMP-9 caused significant reduction of oxytocin-induced contraction of myometrium of virgin rat. Thus, normal pregnancy is associated with reduced myometrium contraction and increased MMPs expression and activity. The results are consistent with the possibility that myometrium stretch and concomitant increase in

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

    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.

    Successful implantation depends on active dialogue between the maternal endometrium and the implanting blastocysts that is well controlled by groups of regulators at the molecular level. Dickkopf2 (Dkk2) is a member of Dickkopf family normally acting as an antagonist of canonical Wnt/beta-catenin signaling, which has been proven to participate in tumorigenesis and early embryo development. In order to explore the potential function of Dkk2 in embryo implantation, the present study investigated the uterine expression and regulation profiles of Dkk2 during periimplantation in mice. Using reverse transcription-polymerase chain reaction, immunohistochemistry and Western blotting, we showed that the mRNA and protein levels of Dkk2 began to increase in the glandular epithelium on day 4, continued to increase on day 5 and then decreased from day 6 of pregnancy. Moreover, on days 5-8 of pregnancy, Dkk2 was increasingly expressed in the deciduum of the uterus, especially around the implanting embryos. In addition, upregulation of Dkk2 was also observed in uteri treated with estrogen (estradiol-17beta) as well as in oil-induced artificial decidualization, indicating that the expression of Dkk2 could be induced by both steroid hormone (estrogen) and the process of decidualization. Furthermore, in the postimplantation uterus, the Dkk2 protein showed an inversed expression with active beta-catenin from day 6 onward, supporting the notion that Dkk2 plays an inhibitory role against canonical Wnt signaling in the context of the decidualizing stroma. Collectively, our data suggests that Dkk2 expression is associated with uterine receptivity changes as well as the process of decidualization and that it might play important roles through inhibition of canonical Wnt signaling in the periimplantation uterus.

    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.

    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.

    Full Text Available The great white shark (Carcharodon carcharias exhibits viviparous and oophagous reproduction. A 4950 mm total length (TL gravid female accidentally caught by fishermen in the Okinawa Prefecture, Southern Japan carried six embryos (543-624 mm TL, three in each uterus. Both uteri contained copious amounts of yellowish viscous uterine fluid (over 79.2 litres in the left uterus, nutrient eggs and broken egg cases. The embryos had yolk stomachs that had ruptured, the mean volume of which was approximately 197.9 ml. Embryos had about 20 rows of potentially functional teeth in the upper and lower jaws. Periodic acid Schiff (PAS-positive substances were observed on the surface and in the cytoplasm of the epithelial cells, and large, secretory, OsO4-oxidized lipid droplets of various sizes were distributed on the surface of the villous string epithelium on the uterine wall. Histological examination of the uterine wall showed it to consist of villi, similar to the trophonemata of Dasyatidae rays, suggesting that the large amount of fluid found in the uterus of the white shark was likely required for embryo nutrition. We conclude that: (1 the lipid-rich fluid is secreted from the uterine epithelium only in early gestation before the onset of oophagy, (2 the embryos probably use the abundant uterine fluid and encased nutrient eggs for nutrition at this stage of their development, and (3 the uterine fluid is the major source of embryonic nutrition before oophagy onset. This is the first record of the lipid histotrophy of reproduction among all shark species.

    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.

    Uteri of mature Egyptian buffalo cows (5-10 years old) were collected at follicular (n=12) and luteal (n=16) phases of estrous cycle to investigate the expression of calbindin-D9k (CaPB-9k) and vitamin D receptor (VDR). This study was done using avidin-biotin immunohistochemistry method. In addition, blood levels of calcium (Ca), vitamin D3 (Vit D), estrogen (E2) and progesterone (P4) were measured. The immunohistochemical findings restricted the expressions of CaBP-9k and VDR to the luminal and glandular epithelia of the endometrium implicating the importance of CaBP-9K and VDR in the function of endometrial epithelium, especially the glandular one, in order to prepare a receptive uterus. On the other hand, the myometrium did not express CaBP-9k or VDR that denies the potential role of CaBP-9k and VDR in the uterine contractility during the estrous cycle of Egyptian buffalo. All of Ca, Vit D, and P4 blood levels significantly (P<0.05) increased during luteal phase however, blood level of E2 significantly (P<0.05) increased during follicular phase. The expressions of CaBP-9k and VDR in the uterus of Egyptian buffalo were significantly (P<0.05) higher during luteal (P4 dominant) phase than during the follicular (E2 dominant) phase indicating that P4 up-regulates the expressions of CaBP-9k and VDR. In view of these observations, this study represents the first characterization of CaBP-9K and VDR expression in the uterus of Egyptian buffalo and suggests the pivotal role of CaBP-9k and VDR in the uterine receptivity. Furthermore, it demonstrates the regulatory role of P4 for expressions of CaBP-9k and VDR in buffalo uterus. PMID:27142230

    Following bidirectional communication, the conceptus and the uterine epithelium must establish a proper cell-cell interaction, resulting in the progression of implantation processes. To clarify the mechanism of conceptus attachment to the uterine endometrium, we studied whether vascular cell adhesion molecule (VCAM1) was expressed in bovine conceptuses or endometrium during the peri-attachment period. Uterine VCAM1 expression was minimal in day 17 (day 0=day of estrus) cyclic and pregnant animals, but increased between days 20 and 22 of pregnancy. In the intercaruncular regions, VCAM1 protein was localized to the luminal and glandular epithelia, whereas in the caruncular regions, VCAM1 protein was detected in the stroma and endothelia of the uterine endometrium. In cultured endometrial epithelial cells (EECs), VCAM1 expression was up-regulated when treated with uterine flushings or growth factor and further increased when EECs were cocultured with bovine trophoblast CT1 cells. VCAM1 expression in CT1 cells was also up-regulated with the use of uterine flushings, and further increased when these cells were cocultured with EECs. Expression of VCAM1 receptor, integrin α 4 (ITGA4) mRNA, increased significantly in day 22 conceptuses. In day 22 pregnant uteri, VCAM1 protein was found in both EECs and conceptuses, but ITGA4 was localized only to trophoblasts. These observations indicate that cell-cell interactions between conceptuses and uterine epithelial cells are required for sufficient VCAM1 and ITGA4 expression in the bovine species and suggest that uterine VCAM1 and conceptus ITGA4 play a role in the establishment of conceptus adhesion to the uterine endometrium.

    Full Text Available Abstract Backgroud Bone mineral density (BMD is a marker of long-term estrogen exposure. BMD measurement has been used in this context to investigate the association of estrogen with breast cancer risk in three cohorts. In order to assess further BMD as a predictor of estrogen related cancer risk, the association of BMD with colorectal and corpus uteri cancer was investigated in the NHANES I Epidemiologic Followup Study (NHEFS cohort along with breast cancer and prostate cancer. Methods Participants were members of the NHEFS cohort who had BMD measurement in 1974–1975. Age, race, and BMI adjusted rate ratios and 95% confidence intervals were calculated for incidence of cancers of the corpus uterus, breast, colorectum, prostate, and of osteoporosis and hip fracture related to baseline BMD. Results Data were available for 6046 individuals. One hundred cases of breast cancer, 94 prostate cancers, 115 colorectal cancers, 29 uterine cancers, 110 cases of hip fracture and 103 cases of osteoporosis were reported between 1974 and 1993. Hip fracture and osteoporosis were both significantly inversely associated with BMD. Uterine cancer was positively associated (p = 0.005, test for linear trend and colorectal cancer negatively associated (p = 0.03 with BMD. No association was found between elevated BMD and incidence of breast cancer (p = 0.74 or prostate cancer (p = 0.37 in the overall cohort, although a weak association was seen between BMD and subsequent breast cancer incidence when BMD was measured in post-menopausal women (p = 0.04. Conclusion The findings related to cancers of the uterus and colorectum as well as the weak association of BMD with breast cancer strengthen the use of BMD as a marker of estrogen exposure and cancer risk.

  12. 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.

    The histomorphometric and proliferative characteristics of the collared peccary (Tayassu tajacu) placenta and uterus were analyzed. The material was examined by standard histological techniques and histochemistry (PAS, Perls and Alcian Blue pH 0.5 and 2.5%) and the cellular proliferation by AgNORs and flow cytometry. All the analyzed morphometric variables differed between pregnant and non-pregnant uteri in the luteal phase using the Dunnet test. Height and gland diameter of uterine glands increased linearly during pregnancy, with an intense positive PAS and Perls reaction in all stages. The cells with more than seven AgNORs per nuclei and the cells in the G2M cell cycle phase in the maternal tissue also increased after 70 days of pregnancy. The uteroplacental ridges had a linear increase in size with two distinct areas, base and top, with uterine epithelium and trophoblastic cells changing their morphology following the placental ridge development. Flow cytometry analysis showed the percentage of cells in each cell cycle phase with a quadratic behavior for stages G2/M in the maternal tissue, suggesting an increase in proliferative capacity of maternal tissue after 65 days of pregnancy. The same quadratic effect was observed in the G0/G1 phase in both maternal and fetal tissues. Cells in apoptosis showed cubic behavior in both tissues. The morphometric and cellular dynamic aspects observed in this study have not been previously described and they extend our knowledge of functions relating to maternal-fetal dynamics in this species.

    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

  15. 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.

    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.

    The great white shark (Carcharodon carcharias) exhibits viviparous and oophagous reproduction. A 4950 mm total length (TL) gravid female accidentally caught by fishermen in the Okinawa Prefecture, Southern Japan carried six embryos (543-624 mm TL, three in each uterus). Both uteri contained copious amounts of yellowish viscous uterine fluid (over 79.2 litres in the left uterus), nutrient eggs and broken egg cases. The embryos had yolk stomachs that had ruptured, the mean volume of which was approximately 197.9 ml. Embryos had about 20 rows of potentially functional teeth in the upper and lower jaws. Periodic acid Schiff (PAS)-positive substances were observed on the surface and in the cytoplasm of the epithelial cells, and large, secretory, OsO4-oxidized lipid droplets of various sizes were distributed on the surface of the villous string epithelium on the uterine wall. Histological examination of the uterine wall showed it to consist of villi, similar to the trophonemata of Dasyatidae rays, suggesting that the large amount of fluid found in the uterus of the white shark was likely required for embryo nutrition. We conclude that: (1) the lipid-rich fluid is secreted from the uterine epithelium only in early gestation before the onset of oophagy, (2) the embryos probably use the abundant uterine fluid and encased nutrient eggs for nutrition at this stage of their development, and (3) the uterine fluid is the major source of embryonic nutrition before oophagy onset. This is the first record of the lipid histotrophy of reproduction among all shark species.

    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 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.

    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

  3. 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

    Full Text Available The transforming growth factor β (TGFβ superfamily proteins are principle regulators of numerous biological functions. Although recent studies have gained tremendous insights into this growth factor family in female reproduction, the functions of the receptors in vivo remain poorly defined. TGFβ type 1 receptor (TGFBR1, also known as activin receptor-like kinase 5, is the major type 1 receptor for TGFβ ligands. Tgfbr1 null mice die embryonically, precluding functional characterization of TGFBR1 postnatally. To study TGFBR1-mediated signaling in female reproduction, we generated a mouse model with conditional knockout (cKO of Tgfbr1 in the female reproductive tract using anti-Müllerian hormone receptor type 2 promoter-driven Cre recombinase. We found that Tgfbr1 cKO females are sterile. However, unlike its role in growth differentiation factor 9 (GDF9 signaling in vitro, TGFBR1 seems to be dispensable for GDF9 signaling in vivo. Strikingly, we discovered that the Tgfbr1 cKO females develop oviductal diverticula, which impair embryo development and transit of embryos to the uterus. Molecular analysis further demonstrated the dysregulation of several cell differentiation and migration genes (e.g., Krt12, Ace2, and MyoR that are potentially associated with female reproductive tract development. Moreover, defective smooth muscle development was also revealed in the uteri of the Tgfbr1 cKO mice. Thus, TGFBR1 is required for female reproductive tract integrity and function, and disruption of TGFBR1-mediated signaling leads to catastrophic structural and functional consequences in the oviduct and uterus.

    Cervical patency is considered to be important for uterine drainage after mating or artificial insemination (AI), and failure to relax or premature tightening of the cervix can lead to persistent endometritis. This study investigated the hypothesis that cervical occlusion after AI increases accumulation of fluid, polymorphonuclear leukocytes (PMNs), and cytokines in the uterine lumen. Endometrial swabs were obtained from 29 normal cyclic mares during the first, third, and fifth estrus and biopsies during the first and fifth estrus. All mares were inseminated during the second and fourth estrus. In either the second or fourth estrus, a clamped catheter was inserted into the uterus immediately after AI. Accumulation of intrauterine fluid was evaluated by transrectal ultrasonography at 0, 6, 25, and 48 hours. Fluid was drained from the catheter at either 25 hours (TxA) or 6 and 25 hours after AI (TxB). In the control estrus (TxC, no catheters), fluid was obtained by a tampon at 25 hours after AI. The uteri were then lavaged with Ringer's solution, after which the catheters were withdrawn. Sequences of treatments in the second and fourth estrus were A followed by C, C followed by A, B followed by C, and C followed by B in groups AC, CA, BC, and CB, respectively. Five mares lost their catheters and were excluded from the study. Scores for total inflammation, gland dilation, and lymphatic lacunae in the uterine biopsies did not differ significantly between groups or estrous periods. In contrast, periglandular fibrosis scores increased in all groups during the experiment. At 25 hours after AI in the second estrus, the mares with the catheters had larger accumulations of fluid (P insemination results in pronounced inflammation of the mare's endometrium. Furthermore, this kind of severe insult may lead to permanent pathologic changes in the endometrium, including fibrosis. PMID:26586278

    Full Text Available We have investigated the potential advantages of transcervical artificial insemination into the caudal portion of the uterus (corpus uteri, compared with conventional sperm-dose deposition into the posterior region of the cervix. Three experiments was carried out to investigate: (1 the influence of insemination-dose volume, (2 sperm number per dose and (3 type of insemination catheter on sows fertility (farrowing rate and litter size. Classic intracervical insemination was performed in the total of 50 sows (25 inseminated with 100ml doses and 25 with 50ml doses. Intrauterine insemination was performed in the total of 50 sows (25 inseminated with 100ml doses and 25 with 50ml doses. Significant greater farrowing rate (88% and live born piglet per litter (10,77 or 11,86 was found after intrauterine insemination, then after intracervical insemination (76 or 72% farrowing rate, and 10,42 or 9,89 live born piglets per litter. Classic intracervical insemination was performed in the total of 90 sows, with different catheter type. Intrauterine insemination was performed in the total of 90 sows, with 5x109,3,7x109 or 2,5x109 spermatozoa per dose. No significant differences in farrowing rate was found between intracervical and intrauterine insemination (83,3 to 86,7%. Significant greater live born piglet per litter was found after intrauterine insemination with 2,5x109 spermatozoa per dose. Obtained results suggest that intrauterine insemination can be performed by significant reduction of insemination dose volume and sperm number in dose, without decreasing sows fertility. It can result in significant increasing of boar reproductive efficiency.

    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.

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

    International Nuclear Information System (INIS)

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

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.

    Transvaginal sonography has become an important tool for assessing the gravid cervix uteri, especially in patients at risk for cervical incompetence and preterm delivery. The purpose of our prospective study was to evaluate interobserver variability in measurements of the cervical length and, as a second step, improve the reproducibility and interobserver discrepancy by the introduction of quality control standards when producing and measuring the image of the cervix. Before the introduction of these standards we obtained 46 measurements and observed a mean cervical length (internal to external os) of 33.7 mm (range 26-52 mm) and an interobserver average discrepancy of 3.04 mm (range 0-6 mm). Later, measurements were obtained only when the following conditions were assured and visualized on the screen: (1) the internal os is either flat or is an isosceles triangle; (2) the whole length of the cervical canal can be observed; (3) a symmetric image of the external os can be obtained; and (4) the distance from the surface of the posterior lip to the cervical canal is equal to the distance from the anterior lip to the cervical canal. After the implementation of these quality control standards, 70 measurements were performed obtaining a mean length of 35.3 mm (range 27-51) and an average interobserver discrepancy of 1.24 mm (range 0-4). Thus the measurement error was significantly lower following introduction of quality control standards. Furthermore, the coefficient of variation dropped from 7.1% to 3.3% after the introduction of the guidelines. We believe that these guidelines could be helpful by making the measurements of the cervical length more accurate, reducing the interobserver variability, improving the reproducibility and promoting the role of transvaginal sonography in monitoring the incompetent cervix.

    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 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

    Full Text Available Abstract Background The rising rates of primary caesarean section have resulted in a larger obstetric population with scarred uteri. Subsequent pregnancies in these women are risk-prone and may complicate. Besides ensuring standardised management, care pathways could be used to evaluate for perinatal outcomes in these high risk pregnancies. We aim to demonstrate the use of a care pathway for vaginal birth after caesarean section as a service evaluation tool to determine perinatal outcomes. Methods A retrospective service evaluation by review of delivery case notes and records was undertaken at the Aga Khan University Hospital, Nairobi, Kenya between January 2008 and December 2009 Women with ≥2 previous caesarean sections, previous classical caesarean section, multiple gestation, breech presentation, severe pre-eclampsia, transverse lie, placenta praevia, conditions requiring induction of labour and incomplete records were excluded. Outcome measures included the proportion of eligible women who opted for test of scar (ToS, success rate of vaginal birth after caesarean section (VBAC; proportion on women opting for elective repeat caesarean section (ERCS and their perinatal outcomes. Results A total of 215 women with one previous caesarean section were followed up using a standard care pathway. The median parity (minimum-maximum was 1.01234. The other demographic characteristics were comparable. Only 44.6% of eligible mothers opted to have a ToS. The success rate for VBAC was 49.4% with the commonest (31.8% reason for failure being protracted active phase of labour. Maternal morbidity was comparable for the failed and successful VBAC group. The incidence of hemorrhage was 2.3% and 4.4% for the successful and failed VBAC groups respectively. The proportion of babies with acidotic arterial PH ( Conclusions Besides ensuring standardised management, care pathways could be objective audit and service evaluation tools for determining perinatal outcomes.

    Full Text Available Signal transducers and activators of transcription 3 (Stat3 has been identified as an important signal transducer in the invasive phenotype of the trophoblasts cells in in vitro studies. However, the in situ distribution and patterns of expression of this molecule in trophoblast cells during the development of the placenta are still under-elucidated. Mice uteri of gestational ages between 7 and 14 days of pregnancy (dop were fixed in methacarn and processed with immunoperoxidase techniques for detection of Stat3 and its phosphorylation at serine (p-ser727 residues, as well as the suppressor of cytokine signaling 3 (Socs3 expression. Stat3 was observed at 7 through 9 dop in both the antimesometrial and mesometrial deciduas, while continued immunoreactivity between 10 and 13 dop was seen only in the mesometrial decidua. In the placenta, Stat3 was detected in the cytotrophoblast cells of labyrinth and giant trophoblast cells between 10 and 14 dop. Immunoreactivity for Stat3 was also seen in trophoblast cells surrounding the maternal blood vessels. On days 10 and 11 of pregnancy, p-ser727 was detectable in the mesometrial decidua and in giant trophoblasts, while during 12-14 dop in the spongiotrophoblast region. In addition, Socs3 was immunodetected in maternal and placental tissues, principally in the giant trophoblast cells during the whole period of the study. The present in situ study shows the distribution of Stat3, its serine activation and Socs3 in different maternal and fetal compartments during murine placental development, thus further supporting the idea that they play a role during physiological placentation in mice.

    Objective To investigate the genetic aberrations in extranodal marginal zone lymphoma of mueosa-associated lymphoid tissue (MALT) lymphomas from different sites of the body in Chinese patients. Methods Two hundred and seventeen paraffin-embedded MALT lymphoma specimens from 11 major sites were studied with interphase fluorescence in situ hybridization (FISH) to detect t(11; 18) (q21;q21)/API2-MALT1, t(1; 14) (p22; q32)/IGH-BCL10, (14; 18) (q32; q21)/IGH-MALT1 and BCL6 gene involved chromosome translocations. Results These translocations were mutually exclusive and detected in 21% (46/217) of the cases, including t(11;18) (q21;q21) API2-MALT1 13% (29/217), t (1;14)(p22 ;q32) IGH-BCLIO in 1% (3/217), t(14;18) (q32;q21) IGH-MALT1 1% (2/217), BCL6 involved translocation in 2% (4/217) and IGH-unknown translocation partner in 4% (8/217). t(11; 18) (q21;q21)API2-MALT1 was found with the highest frequency in MALT lymphoma from lungs (47% , 8/17) and small intestine (29%, 4/14), followed by salivary gland (17%, 1/6), stomach (14%, 12/84) and ocular adnexae (6% , 4/68). t(1 ;14) (p22;q32) was only detected in lungs (12%, 2/17) and stomach (1%, 1/84). t(14;18) (q32;q21) was mainly detected in lungs (6%, 1/17) and ocular adnexae (2%, 1/68). BCL6 gene involved translocation was detected in salivary gland (17% , 1/6) and stomach (4%, 3/84). Conclusions It is demonstrated that the four translocatidns occur with markedly variable frequencies in MALT lymphoma of different sites in Chinese patients. The distributions of these chromosome translocations in Chinese patients are slightly different from those reported in western patients.%目的 探讨中国人不同部位黏膜相关淋巴组织结外边缘区淋巴瘤(MALTL)中分子遗传学异常的发生情况.方法 应用间期荧光原位杂交(FISH)方法,检测217例不同部位MALTL的t(11;18)(q21;q21)/API2-MALT1、t(1;14)(p22;q32)/IGH-BCL10、t(14;18)(q32;q21)/IGH-MALT1和涉及BCL6基因的染色体易位.结果 染色

    Full Text Available OBJETIVO: Verificar a técnica da instilação de colírio em pacientes portadores de glaucoma crônico. MÉTODOS: Estudo prospectivo realizado em 193 pacientes glaucomatosos. Para cada participante era entregue um frasco de colírio lubrificante (Dunason®, Laboratório Alcon, São Paulo, Brasil e solicitado que realizasse uma instilação. RESULTADOS: Os participantes utilizaram, em média, 1,64 ± 1,26 gotas de colírio por instilação e 54,5% dos pacientes fizeram contato do bico do colírio com a superfície ocular. Em 3,1% das instilações nenhuma gota de medicamento atingiu o olho, com o paciente não se dando conta do fato. A oclusão do ponto lacrimal ou a manutenção do olho fechado por dois minutos após a instilação não foi realizada em 87,0% dos participantes, e 61,6% piscaram repetidas vezes imediatamente após instilar a droga. CONCLUSÕES: Verificou-se que a maior parte dos participantes deste estudo efetuou a instilação do colírio de modo incorreto. Isto significa desperdiçar grande parte do conteúdo do frasco, aumentar as possibilidades de toxicidade sistêmica, não aproveitar a plenitude do efeito hipotensor das drogas e contaminar a extremidade do frasco de colírio. Portanto, o ensino da técnica adequada da instilação de colírio é absolutamente necessária para todos os pacientes.PURPOSE: To observe eye drop instillation technique in chronic glaucoma patients.

    , etc. According to months in a year and days in a week, the injuries were almost evenly distributed. Considering the period of a day, even 77.4% of the injuries occurred during daytime, from 10 a.m. to 10 p.m. The highest percentage - 43.5% - of the injuries occurred while working something out of working place, while 24.5% of injuries were inflicted at working places. On admission, the majority of patients - 32.9% had visual acuity L+P+, but this visual acuity ranged from amaurosis to 1.0. There were 746 (45.4% contusion injuries and 870 (53.0% penetrating injuries. The rest were the injuries of other ocular adnexa. The majority of primary wound managements were performed in the first 24 hours of the injury - 67.1%. Conclusion. It may be concluded that working population and students are most commonly injured, and that men are five times more frequently injured than women; then, a piece of wood, sharp objects and glass are the most often causes of injury; the number of contusion and penetrating injuries is equal, and that required primary surgical wound management is most often performed in the first 24 hours from the injury. Further analysis of these factors suggests that many of these injuries could have been prevented, and consequently long-term treatment and treatment costs could have been evaded. Most important is that permanent disability due to visual impairment or even blindness of the injured eye could have been avoided.

The samples consisted of MALT lymphomas from stomach (53 cases, including 44 cases of low-grade MALT lymphoma and 9 cases of MALT lymphoma with diffuse large B-cell lymphoma component), ocular adnexa (50 cases), salivary gland (20 cases), lung (20 cases), intestine (17 cases), skin (17 cases), liver (8 cases), thyroid (5 cases) and other sites (2 cases from tongue, 1 ease from pancreas, 1 case from larynx, 1 case from vocal cords and 1 case from kidney). Fluorescence in-situ hybridization for API2-MALT1 fusion gene, bcl-1O, MALT1 and IgH genes was performed on paraffin sections. Results Among the 196 cases of MALT lymphoma, 25 cases (12. 8%) possessed API2-MALTI fusion gene. The positive rates in various sites were significantly different (P=0.002), as follows: 45.0% (9/20) in lung, 22. 7%(10/44) in stomach (without large cell component), 15.0%(3/20) in salivary gland, 2 of 17 cases in intestine and 2.0% (1/50) in ocular adnexa. The fusion gene was not detected in the 9 cases of gastric MALT lymphoma with large cell transformation. It was also negative in the MALT lymphomas from skin, thyroid and other sites. One of the pulmonary MALT lymphoma cases showed simultaneous aberrations of IgH and MALT1 genes, such as t(14;18)/IgH-MALT1. Two of the gastric MALT lymphoma cases without large cell transformation and one ofthe pulmonary MALT lymphoma cases showed aberrations in both IgH and bcl-10 genes,such as t(1;14)/IgH-bcl-10.Six cases of MALT lymphoma,including 2 cases from salivary gland,2 cases from liver,1 case from thyroid and 1 case from stomach(large cell transformation),showed trisomy 18.On the other hand,3 cases,including 2 cases from stomach and 1 case from intestine,showed MALT1 gene amplification.Condusions In general,specific genetic aberrations have a relatively low frequency of occurrence in MALT lymphomas.The positive rates however show a remarkable difference in tumors of different anatomic sites.This phenomenon may suggest that MALT lymphomas in

    Cervical carcinomas are second most frequent type of women cancer. Success in diagnostics of this disease is due to the use of Pap-test (cytological smear analysis). However Pap-test gives significant portion of both false-positive and false-negative conclusions. Amendments of the diagnostic procedure are desirable. Aetiological role of papillomaviruses in cervical cancer is established while the role of cellular gene alterations in the course of tumor progression is less clear. Several research groups including us have recently named the protein p16INK4a as a possible diagnostic marker of cervical cancer. To evaluate whether the specificity of p16INK4a expression in dysplastic and neoplastic cervical epithelium is sufficient for such application we undertook a broader immunochistochemical registration of this protein with a highly p16INK4a-specific monoclonal antibody. Paraffin-embedded samples of diagnostic biopsies and surgical materials were used. Control group included vaginal smears of healthy women and biopsy samples from patients with cervical ectopia. We examined 197 samples in total. Monoclonal antibody E6H4 (MTM Laboratories, Germany) was used. In control samples we did not find any p16INK4a-positive cells. Overexpression of p16INK4a was detected in samples of cervical dysplasia (CINs) and carcinomas. The portion of p16INK4a-positive samples increased in the row: CIN I – CIN II – CIN III – invasive carcinoma. For all stages the samples were found to be heterogeneous with respect to p16INK4a-expression. Every third of CINs III and one invasive squamous cell carcinoma (out of 21 analyzed) were negative. Overexpression of the protein p16INK4a is typical for dysplastic and neoplastic epithelium of cervix uteri. However p16INK4a-negative CINs and carcinomas do exist. All stages of CINs and carcinomas analyzed are heterogeneous with respect to p16INK4a expression. So p16INK4a-negativity is not a sufficient reason to exclude a patient from the high risk

At the same time.it is also an organ which is likely to suffer from malignant tumor. Each part of the uterus including cervix,corpus uteri,endometrium,myometrium is prone to malignant tumor. Cervical cancer is the most common gynecological malignancies. Persistent infection of high risk papillomavirus is the main reason of precancerous and cervical cancer. The main pathological type was squamous cell carcinoma and adenocarcinoma. Definite diagnosis can depend on cervix biopsy and histopathology. We can judge the severity from the FICO clinical staging. The treatment of early stage cervical cancer is surgery,while in treatment of the middle and advanced stage cervical cancer,radiaotherapy is the core and chemotherapy is the complement. Nowadays targeted therapy provides a new approach to local advanced,recurrent and metastasis cervical cancer. HPV vaccine has been used to prevent the cervical cancer now.

    Infertility and subfertility represent major problems in domestic animals and humans, and the majority of embryonic loss occurs during the first month of gestation that involves pregnancy recognition and conceptus implantation. The critical genes and physiological pathways in the endometrium that mediate pregnancy establishment and success are not well understood. In study one, predominantly Angus heifers were classified based on fertility using serial embryo transfer to select animals with intrinsic differences in pregnancy loss. In each of the four rounds, a single in vitro-produced, high-quality embryo was transferred into heifers on Day 7 postestrus and pregnancy was determined on Days 28 and 42 by ultrasound and then terminated. Heifers were classified based on pregnancy success as high fertile (HF), subfertile (SF), or infertile (IF). In study two, fertility-classified heifers were resynchronized and bred with semen from a single high-fertility bull. Blood samples were collected every other day from Days 0 to 36 postmating. Pregnancy rate was determined on Day 28 by ultrasound and was higher in HF (70.4%) than in heifers with low fertility (36.8%; SF and IF). Progesterone concentrations in serum during the first 20 days postestrus were not different in nonpregnant heifers and also not different in pregnant heifers among fertility groups. In study three, a single in vivo-produced embryo was transferred into fertility-classified heifers on Day 7 postestrus. The uteri were flushed on Day 14 to recover embryos, and endometrial biopsies were obtained from the ipsilateral uterine horn. Embryo recovery rate and conceptus length and area were not different among the heifer groups. RNA was sequenced from the Day 14 endometrial biopsies of pregnant HF, SF, and IF heifers (n = 5 per group) and analyzed by edgeR-robust analysis. There were 26 differentially expressed genes (DEGs) in the HF compared to SF endometrium, 12 DEGs for SF compared to IF endometrium, and three

  4. Parturition in Tsetse Flies: Endocrine Control

    International Nuclear Information System (INIS)

    A problem in tsetse mass rearing facilities is the increased incidence of abortions of underdeveloped larvae or pupariation of larvae within the mother's uterus. We analysed the problem by investigating neural, hormonal and environmental factors controlling parturition. Input from the mother's brain is essential for normal parturition, since a female whose brain is disconnected by ligation fails to deposit her larva. The expulsion of a larva is stimulated by a putative parturition hormone present within the female's uterus. The hormone also elicits abortion when injected into neck ligated females at earlier stages of pregnancy. This report describes attempts to reveal the chemical nature of this hormone by purification of extracts of uteri of Glossina females and identification of behaviourally active fractions using a MALDI-MS instrument. Genomic (BLAST) analysis of the identified sequences did not reveal a significant match with any protein with bioactive properties in other species. However, similarity with various enzymes or structural proteins (and hypothetical proteins) was detected occasionally. In the Glossina genomic and cDNA databases no nucleotide sequence corresponding to the deduced AA sequences was found. Perhaps the deduced sequences are too short to obtain more significant hits both in protein and nucleotide databases. We also made investigations to elucidate environmental influences and physiological mechanisms associated with tsetse parturition. We found that the circadian rhythm of parturition of flies kept in Bratislava (G. m. morsitans, G. f. fuscipes and G. pallidipes) is less pronounced than under natural conditions. The loss of synchrony in the laboratory may have three possible causes: (i) genetic - absence of selective pressure, (ii) environmental - low intensity or absence of an entraining light or temperature stimulus, and (iii) physiological - impaired sensitivity to olfactory stimulation by a hypothetical 'oviposition' pheromone that

    There are five population-based cancer registries in Thailand in different regions of the country. Four of them (Chiang Mai, Khon Kaen, Bangkok, and Songkhla) have been operating since 1988 and the other (Lampang) since the early 1990s. These registries have published regular 3-year cancer incidence reports since the first in 1993 for the period 1989-1991. The objective of this article is to summarize the figures of cancer incidence in Thailand during 1995-1997. The population of Thailand in 1996, at the middle of the period, was 27 million males and 27.5 million females. Information of cancer cases residing in the five provinces was collected and abstracted from different sources. Age-standardized incidence rate (ASR) of cancer in males and females was calculated for each registry and that for the whole country was estimated using the five registries as representatives for the four geographical regions of Thailand. The estimated number of new cancer cases in 1996 for the whole country was 35,539 men and 38,476 women and the ASRs were 149.2 and 125.0 per 10(5) population in men and women respectively. Cancer incidences greatly differed from region to region. Lung cancer was the commonest in Chiang Mai and Lampang in the Northern region in both sexes. The incidence of liver cancer in Khon Kaen in the Northeastern region outnumbered all the others in both sexes; cholangiocarcinoma was the major type of liver cancer. In Bangkok, lung cancer was the most important cancer in males and breast cancer was in females. Though it was lung and cervix uteri cancer that ranked the first in men and women in Songkhla, the rate of oral and pharyngeal cancer was exceptionally higher than in other registries. The geographical variability in cancer patterns in Thailand reflects exposure of the population to different risk factors unique to the different regions. In the study as a whole, there are some methodological weak points in estimating the ASRs and number of cancer cases for the

    Full Text Available Objective: The appropriate interaction between a blastocyst and the endometrium is essential for successful implantation. Numerous factors, including hormone receptors (progesterone receptor, cytokines [leukemia inhibitory factors (LIF], and adherence molecules such as E-cadherin are involved in the cross-talk that occurs between the embryo and endometrium. Studies show that a lack of these genes impact endometrial receptivity. In this study, we compare the expression levels of E-cadherin, LIF, and progesterone receptor (PgR genes in blastocysts that have been obtained from superovulated mice to those obtained from natural cycles.Materials and Methods: In this experimental study, for the experimental group, a total of 17 virgin female NMRI mice (6- 8 weeks old were injected with 7.5 IU pregnant mare serum gonadotropin (PMSG. Their blastocysts (approximately n= 120 were flushed out after 3.5 days, following administration of human chorionic gonadotropin (hCG. The control group consisted of blastocysts from 62 female mice that were mated with male mice. The natural cycle blastocysts were flushed out from the female mice uteri 3.5 days after mating. The expression levels of E-cadherin, LIF, t PgR genes were examined by quantitative real-time reverse-transcriptase polymerase chain reaction (RT-PCR. Data were analyzed by the student’s t-test (one sample t-test.Results: Expression levels of all studied genes were significantly lower in the hormone-treated group compared to the natural cycle blastocysts (p<0.05.Conclusion: Although ovarian stimulation is utilized to obtain more oocytes in ART cycles, it seems that this could disadvantageous to implantation because of the decrease in expression levels of certain genes. Because of the important roles of E-cadherin, LIF, and progesterone receptor in the implantation process, we have shown lower expression levels of these genes in mouse blastocysts obtained from ovarian-stimulated mice than those derived

    Full Text Available Abstract Background Cervical carcinomas are second most frequent type of women cancer. Success in diagnostics of this disease is due to the use of Pap-test (cytological smear analysis. However Pap-test gives significant portion of both false-positive and false-negative conclusions. Amendments of the diagnostic procedure are desirable. Aetiological role of papillomaviruses in cervical cancer is established while the role of cellular gene alterations in the course of tumor progression is less clear. Several research groups including us have recently named the protein p16INK4a as a possible diagnostic marker of cervical cancer. To evaluate whether the specificity of p16INK4a expression in dysplastic and neoplastic cervical epithelium is sufficient for such application we undertook a broader immunochistochemical registration of this protein with a highly p16INK4a-specific monoclonal antibody. Methods Paraffin-embedded samples of diagnostic biopsies and surgical materials were used. Control group included vaginal smears of healthy women and biopsy samples from patients with cervical ectopia. We examined 197 samples in total. Monoclonal antibody E6H4 (MTM Laboratories, Germany was used. Results In control samples we did not find any p16INK4a-positive cells. Overexpression of p16INK4a was detected in samples of cervical dysplasia (CINs and carcinomas. The portion of p16INK4a-positive samples increased in the row: CIN I – CIN II – CIN III – invasive carcinoma. For all stages the samples were found to be heterogeneous with respect to p16INK4a-expression. Every third of CINs III and one invasive squamous cell carcinoma (out of 21 analyzed were negative. Conclusions Overexpression of the protein p16INK4a is typical for dysplastic and neoplastic epithelium of cervix uteri. However p16INK4a-negative CINs and carcinomas do exist. All stages of CINs and carcinomas analyzed are heterogeneous with respect to p16INK4a expression. So p16INK4a-negativity is

    Full Text Available Abstract Background Selective estrogen receptor modulators (SERMs have been developed in order to create means to control estrogenic effects on different tissues. A major drawback in treatment of estrogen receptor (ER positive breast cancer with the antagonist tamoxifen (TAM is its agonistic effect in the endometrium. Raloxifene (RAL is the next generation of SERMs where the agonistic effect on the endometrium has been reduced. Methods The aim of the present study was to determine the effect of SERM treatment on the uterus, as assessed by proliferation markers and several factors involved in uterine growth. Ovariectomized (ovx rats were treated with estradiol (E2, tamoxifen (TAM, RAL, ICI182780 (ICI or vehicle (OVX-controls. We studied the effects on mRNA levels of the growth hormone (GH receptor, insulin-like growth factor-I (IGF-I, ERα and ERβ. In addition, by immunohistochemistry the proliferation markers PCNA and Ki-67, as well as ERα and ERβ, were detected. Results The uterine weight of the rats treated with E2 or TAM was increased as compared to OVX-controls. The uterine GH-receptor mRNA level was highest in the E2 treated animals. In ICI treated rats no GH-receptor mRNA could be detected. The IGF-I mRNA level increased 16-fold in uteri of the TAM treated group and 9-fold in the E2 treated rats as compared to OVX-controls. The ERα mRNA level was increased in the E2 treated rats, while the ERβ mRNA level was increased after TAM treatment. The proliferation, as assessed by PCNA, was lowest in ICI treated animals. Conclusions The uterine wet weight, the LE height and the GH-receptor mRNA levels showed similar patterns, indicating that GH is involved in the regulation of uterine weight. Tamoxifen, which has been related to increased incidence of endometrial carcinoma in women, dramatically increased IGF-I mRNA levels in rat uterus. Since proliferation was not higher in TAM and E2 treated rats than in OVX controls, this assay of simple

    Full Text Available Abstract Background Transient receptor potential channel type 6 (TRPV6 and Calbindin-D9k (CaBP-9k are involved in the active calcium (Ca2+ transport mechanism in many tissues including placenta and uterus, suggesting a role in the establishment and maintenance of pregnancy. Moreover, TRPV6 and CaBP-9k seem to support the materno-fetal Ca2+ transport that is crucial for fetal Ca2+ homeostasis, bone growth and development. However, it is unknown if these proteins are also involved in the aetiology of pathologies associated with parturition in cows, such as retained fetal membranes (RFM. The aim of the current study was to create an expression profile of uterine and placentomal TRPV6 and CaBP-9k mRNAs and proteins during pregnancy and postpartum in cows with and without fetal membrane release. Methods Uteri and placentomes of 27 cows in different stages of pregnancy and placentomes of cows with and without RFM were collected. Protein and mRNA expression of TRPV6 and CaBP-9k was investigated by real-time PCR, immunohistochemistry and Western blot. Results In the uterine endometrium, highest TRPV6 and CaBP-9k expression was found in the last trimester of pregnancy, with a particular increase of protein in the glandular epithelium. In the placentomes, a gradual increase in TRPV6 mRNA was detectable towards parturition, while protein expression did not change significantly. Placentomal CaBP-9k expression did not change significantly throughout pregnancy but immunohistochemistry revealed an increase in staining intensity in the maternal crypt epithelium. Immunohistochemical, stronger placental CaBP-9k signals were seen in animals with RFM compared to animals with an undisturbed fetal membrane release, while protein levels, measured by Western blot analyses did not change significantly. Conclusions The results of the present study demonstrate a dynamic expression of TRPV6 and CaBP-9k during pregnancy in the bovine uterine endometrium and placentomes

    The aim of the present study was to evaluate the efficacy and beta 2-adrenoceptor (AR) selectivity of KUR-1246, a new uterine relaxant. Inhibition of spontaneous or drug-induced uterine contractions by KUR-1246 was evaluated in pregnant rats and rabbits by an organ bath method or by a balloon method. The selectivity of KUR-1246 was assessed simultaneously in organs isolated from late-pregnant rats. The affinity of KUR-1246 for human beta 1-, beta 2-, and beta 3-ARs was determined using two radioligands. KUR-1246 suppressed both spontaneous and drug-induced contractions in isolated uteri, the rank order of potency being isoproterenol > KUR-1246 > terbutaline > ritodrine. ICI-118551 (selective beta 2-AR antagonist) competitively antagonized the KUR-1246-induced inhibition of spontaneous uterine contractions, but CGP-20712A (selective beta 1-AR antagonist) and SR-58894A (selective beta 3-AR antagonist) did not. All beta-AR agonists tested produced significant inhibition of spontaneous uterine contractions in vivo: ED(30) value for KUR-1246 was 0.13 microg/kg/min, a potency about 6 times and 400 times greater than that of terbutaline and ritodrine, respectively. In contrast, the positive chronotropic effect was minimal in KUR-1246-treated rats. KUR-1246 displaced radioligand binding to beta 1-, beta 2-, and beta 3-ARs, the pK(i) values being 5.75 +/- 0.03, 7.59 +/- 0.08, and 4.75 +/- 0.03 for beta 1-, beta 2-, and beta 3-ARs, respectively. For the selectivity of KUR-1246 for human beta 2-AR, we obtained values of 39.2 ([IC(50) for beta 1-AR]/[IC(50) for beta 2-AR]) and 198.2 ([IC(50) for beta 3-AR]/[IC(50) for beta 2-AR]), indicating an apparently higher affinity for human beta 2-AR than for other beta-AR subtypes. The present study clearly demonstrated that KUR-1246 is a more selective beta 2-AR agonist than the drugs presently used for relaxing uterine muscle.

    The aim of the present study was to investigate the safety and efficacy of deslorelin, a GnRH agonist, implants in suppressing estrus behavior and matings in a controlled ambient environment in feline queens in the presence of a tomcat. Local and utero-ovarian side effects of deslorelin implants were also investigated. The queens were housed in groups and assigned to one of three treatments: group 1 received 9.5 mg deslorelin implants (N = 14), group 2 received 5 mg megestrol acetate tablets and 9.5 mg deslorelin implants (N = 7), and group 3 were given placebo implants (N = 7). All implants were placed subcutaneously cranial to the interscapular region under xylazine hydrochloride sedation. Ovarian activity was monitored by fecal estradiol (E(2)) analyses. The animals were observed daily and checked individually at three-day intervals for behavioral signs of estrus. After 18.5 mo of trial, queens were ovariohysterectomized, and ovaries and uteri were weighed and evaluated histologically. E(2) levels were significantly lower in group 1 and 2 than in group 3 with an average of 128.48 ± 19.97 ng/g, 90.44 ± 7.16 ng/g and 283.26 ± 39.21 ng/g, respectively, excepting the first week of treatment. After inserting implants an initial estrus-like increase in fecal E(2) concentrations occurred in all treated queens except one female in group 2. Ovarian and uterine weights were significantly different among the groups (P < 0.01), and were lowest in groups 1 and 2. Primordial and primary follicle numbers were significantly higher in groups 1 and 2 than in group 3 (P < 0.001). Endometrial gland, antral follicle, and corpus luteum (CL) numbers were highest in group 3 (P < 0.01, 0.001, and 0.001, respectively) compared with groups 1 and 2. Deslorelin implants successfully suppressed estrus behavior and E(2) secretion in queens for 18.5 mo of the study period. Further investigations are needed to demonstrate the effects of GnRH agonists on ovarian interstitial tissue. PMID

    Between 1998-2002, 16,952 new cases of cancer were registered in Navarre. In men, the most frequently diagnosed cancers were in the following order: prostate, lung, colon and rectum, bladder and stomach, which accounted for 63.2%. In women, the sites were breast, colon and rectum, corpus uteri, stomach and ovary, which accounted for 57.6% of the cases. In the same period, 1998-2002, 4,127 men and 2,470 women died from cancer. Sixty percent of all deaths due to malign tumours in men were due to cancer of the lung, prostate, colon and rectum, stomach and bladder. In women this was due to cancers of colon and rectum, breast, stomach, pancreas and lung, which accounted for 49% of the cases. In men in Navarre there has been an increase in the incidence rates of cancer of the prostate, kidney and non-Hodgkin lymphoma. Avoidable cancers such as those related to smoking (lung, oral cavity and pharynx or pancreas) continue to rise, and represent a greater global risk of dying from cancer in the latest period studied than in the decades of the 1970s and 1980s. From 1995 up to the present, mortality due to cancer has moved from occupying the second place to become the first cause of death among men in Navarre. The global risk of death due to cancer in men is now equal to the first period studied, 1975-1977. Amongst women the global risk of death due to cancer fell by 25% between 1975 and 2002, basically at the cost of breast and stomach cancer. Tumours related to smoking increased both in mortality and in incidence and appear as a significant health problem amongst women in Navarre. Breast cancer has increased in incidence, with lower mortality figures than those of the first period 1975-1977. Invasive cancer of the cervix remains at very low rates in comparison with many European countries, including Spain. In both sexes colorectal and skin cancer has increased, while the incidence and mortality of stomach cancer continues to fall. PMID:17898820

    From 1962 to 1970 about 200 abdominal aortographies were performed in Department of Radiology of National Medical Center, Seoul, Korea, with percutaneous retrograde seldinger catheterization technique. The 200 cases of the abdominal aortography were analyzed as followings. 1) The sex ratio of all patients was 105 (52.5%) males to 95 (47.5%) females. And high incidence was noted in middle age group. (46 patients were from 30 years to 40 years of age) 2) Radiological findings were grouped as 62 (31%) vascular lesion, 113 (56.5%) visceral or other expanding lesions and 29 (14.5%) angiographically nonspecific findings. Total is over 200 due to double lesions in 4 patients. 3) The 62 vascular lesions were composed of 40 aortitis, 28 renal hypertension etc. a) The 40 aortitis was divided into 25 artherosclerotic and 15 nonspecific. The 15 nonspecific aortitis revealed segmental narrowing (2-4 cm) with collaterals. b) In 28 renal hypertension, 17 cases were combined with aortitis, but not in 11 cases (Pure renal hypertension), and 19 cases were unilateral. 4) The highest incidence in 113 (56.5%) visceral or other expanding lesions, was renal lesions (88 cases), and other lesions, such as 12 retroperitoneal masses, 9 liver and pancreatic masses were also noted. The 88 renal lesions were composed of 37 renal tbc, 17 hydronephrosis (excluding tbc hydro), Tumors, 10 cyst etc. a) The most significant findings of renal tuberculosis in renal arteriogrpahy was rarefaction of contrast staining in involved area which was noted in 32 cases (87%) out of 37 renal Tuberculosis. b) All 12 hypernephroma, 1 wilm's tumor, metastaic tumor from fibromyomata uteri revealed pathological vessels and tumor stainings, however these findings were not noted in 2 ureteral carcinoma involving renal pelvis. 5) No permanent complications arose after abdominal aortography.

    The objective of the present study was to estimate cancer risk associated with the low-level radiation exposure of an average annual effective dose of 6.4 mSv (including internal exposure) in the high background-radiation areas (HBRA) in Yangjiang, China. The mortality survey consisted of two steps, i.e., the follow-up of cohort members and the ascertainment of causes of death. The cohort members in HBRA were divided into three dose-groups on the basis of environmental dose-rates per year. The mortality experiences of those three dose groups were compared with those in the residents of control areas by means of relative risk (RR). During the period 1987-1995, we observed 926,226 person-years by following up 106,517 subjects in the cohort study, and accumulated 5,161 deaths, among which 557 were from cancers. We did not observe an increase in cancer mortality in HBRA (RR=0.96, 96% CI, 0.80 to 1.15). The combined data for the period 1979-95 included 125,079 subjects and accumulated 1,698,316 person-years, observed 10,415 total deaths and 1,003 cancer deaths. The relative risk of all cancers for whole HBRA as compared with the control area was estimated to be 0.99 (95% CI, 0.87 to 1.14). The relative risks of cancers of the stomach, colon, liver, lung, bone, female breast and thyroid within whole HBRA were less than one, while the risks for leukemia, cancers of the nasopharynx, esophagus, rectum, pancreas, skin, cervix uteri, brain and central nervous system, and malignant lymphoma were larger than one. None of them were significantly different from RR=1. Neither homogeneity tests nor trend tests revealed any statistically significant relationship between cancer risk and radiation dose. We did not find any increased cancer risk associated with the high levels of natural radiation in HBRA. On the contrary, the mortality of all cancers in HBRA was generally lower than that in the control area, but not statistically significant. (author)

    Full Text Available Abstract Background Comparing survival of patients with a single tumour and patients with multiple primaries poses different methodological problems. In population based studies, where we cannot rely on detailed clinical information, the issue is disentangling the share of survival probability from the first and second cancer, and their compounded effect. We examined three hypotheses: A the survival probability since the first tumour does not change with the occurrence of a second tumour; B the probability of surviving a tumour does not change with the presence of a previous primary; C the probabilities of surviving two subsequent primary tumours are independent (additivity hypothesis on mortality rates. Methods We studied the survival probabilities modelling mortality rates according to hypotheses A, B and C. Mortality rates were calculated using Aalen-Johansen estimators which allowed to discount for the lag-time survival before developing a second tumour. We applied this approach to a cohort of 436 women with breast cancer (BC and a subsequent tumour in the resident population of Turin, Italy, between 1985 and 2002. Results We presented our results in term of a Standardised Mortality Ratio calculated (SMRAJ after 10 years of follow-up. For hypothesis A we observed a significant excess mortality of 2.21 (95% C.I. 1.94 – 2.45. Concerning hypothesis B we found a not significant SMRAJ of 0.98 (95% C.I. 0.87 – 1.10. The additivity hypothesis (C was not confirmed as it overestimated the risk of death, in fact SMRsAJ were all below 1: 0.75 (95% C.I. 0.66 – 0.84 for BC and all subsequent cancers, 0.72 (95% C.I. 0.55 – 0.94 for BC and colon-rectum cancer, 0.76 (95% C.I. 0.48 – 1.14 for BC and corpus uteri cancer (not significant. Conclusion This method proved to be useful in disentangling the effect of different subsequent cancers on mortality. In our application it shows a worse long-term mortality for women with two cancers than that with

    Full Text Available Background: Cesarean section has come a long way from being a risky & restrictive surgery to one that is safe and quick. Due to a rise in the rates of primary caesarean section globally, repeat cesarean section has also become very common. The chief concern during labor with scarred uteri is that of scar rupture which can have devastating fetal and maternal consequences, including mortality. Several studies monitoring for the features of scar rupture like abnormal cardiotocography (CTG, severe abdominal pain persisting between contractions, acute onset scar tenderness, hematuria or abnormal vaginal bleeding, maternal tachycardia or shock, cessation of uterine activity and loss of station of the presenting part exist with the exception of scar tenderness which has not been evaluated separately in any study. The present prospective observational study was undertaken in a tertiary care hospital to evaluate the sensitivity and specificity of scar tenderness as a sign of scar complications in labor. Methods: 78 women with one previous cesarean delivery in spontaneous labor at term undergoing trial of scar were monitored for progress of labor and observed for vaginal bleeding, scar tenderness, maternal pulse and blood pressure every 30 minutes. Scar tenderness was elicited by pressing below and behind the pubic symphysis in between uterine contractions while engaging the woman in conversation and noting for a visible wince. Fetal heart rate auscultation was done as per protocol. Trial of scar was terminated for scar tenderness, unexplained maternal tachycardia, fresh vaginal bleeding, fetal heart rate abnormalities and non-progress of labor. Results: The sensitivity and specificity of scar tenderness as a predictor of scar complications was 92.3% and 3.8%, while accuracy was 33.3%. The likelihood ratio of a positive sign of scar tenderness being associated with scar complications in labour is 1.48. Maternal tachycardia was not a significant predictor

    The aim of this study was to locate the candidate tumor suppressor genes (TSGs) loci in the chromosomal 4p15-16, 4q22-23 and 4q34-35 regions associated with the development of uterine cervical carcinoma (CA-CX). Deletion mapping of the regions by microsatellite markers identified six discrete areas with high frequency of deletions, viz. 4p16.2 (D1: 40%), 4p15.31 (D2: 35-38%), 4p15.2 (D3: 37-40%), 4q22.2 (D4: 34%), 4q34.2-34.3 (D5: 37-59%) and 4q35.1 (D6: 40-50%). Significant correlation was noted among the deleted regions D1, D2 and D3. The deletions in D1, D2, D5 and D6 regions are suggested to be associated with the cervical intraepithelial neoplasia (CIN), and deletions in the D2, D3, D5 and D6 regions seems to be associated with progression of CA-CX. The deletions in the D2 and D6 regions showed significant prognostic implications (P = 0.001; 0.02). The expression of the candidate TSG SLIT2 mapped to D2 region gradually reduced from normal cervix uteri -->CIN --> CA-CX. SLIT2 promoter hypermethylation was seen in 28% CIN samples and significantly increased with tumor progression (P = 0.04). Significant correlation was seen between SLIT2 deletion and its promoter methylation (P = 0.001), indicating that both these phenomena could occur simultaneously to inactivate this gene. Immunohistochemical analysis showed reduced expression of SLIT2 in cervical lesions and CA-CX cell lines. Although no mutation was detected in the SLIT2 promoter region (-432 to + 55 bp), CC and AA haplotypes were seen in -227 and -195 positions, respectively. Thus, it indicates that inactivation of SLIT2-ROBO1 signaling pathway may have an important role in CA-CX development.

  19. Uncertainty in hyperthermia treatment planning: the need for robust system design

    Hyperthermia treatment planning (HTP) is an important tool to improve the quality of hyperthermia treatment. It is a practical way of designing new hyperthermia systems and can be used to optimize the phase and amplitude settings to achieve optimal heating. One of the main challenges to be dealt with however is the uncertainty in the modeling parameters. The role of dielectric and combined dielectric and perfusion uncertainty on optimization was investigated by means of HTP for six different systems: the 70 MHz AMC-4 (AMC: Academic Medical Center) and AMC-8 system, a 130 MHz version of the AMC-8 system, a three-ring AMC-12 system operating at 130 MHz, the BSD SigmaEye applicator and a dipole applicator with three rings each containing six dipole pairs operated at 150 MHz. For five patients with cervix uteri carcinoma, a patient model was created based on a hyperthermia planning CT. Variation of tissue parameters resulted in 16 dielectric models for every patient. In addition, four thermal models were created to study the combined effect of perfusion and dielectric uncertainty. The impact of dielectric uncertainty on optimization is found to be clearly dependent on the number of channels and increased from 0.5 °C for four channels to 1.5 °C for the 18-channel system. As a result, the potential gain relative to the AMC-4 system for the 70 MHz AMC-8 system was found to be largely compromised, while for the remaining systems a robust improvement in T90 was observed. The dipole applicator showed the best target heating for two out of five patients, while for three others heating efficacy was comparable to the 130 MHz AMC-12 system or the 130 MHz AMC-8 system (one patient). Considering the increase in complexity when the number of channels is increased from 12 to 18, the AMC-12 system is considered as a good compromise between heating efficacy and robustness while still being a manageable heating system in clinical practice.

    OBJECTIVE To evaluate the feasibility of intra-operative detection of sentinel lymph nodes (SLN) in the patient with endometrial cancer (EC).METHODS Thirty-one patients with Stage Ⅰ and Ⅱ endometrial cancer, who underwent a hysterectomy and a lymphadenectomy,were enrolled in the study. At laparotomy, methylene blue dye tracer was injected into the subserosal myometrium of corpus uteri at multiple sites, and dye uptake into the lymphatic channels was observed. The blue nodes which were identified as SLNs were traced and excised. The other nodes were then removed. All of the excised nodes were submitted for pathological hematoxylin and eosin (H&E) staining examination.RESULTS Failure of dye uptake occurred in 4 of the 31 cases (12.9%) because of spillage, and no lymphatic coloration was observed there. Lymphatic staining was clearly observable as blue dye diffused to the lymphatic channels of the uterine surface and the infundibulopelvic ligaments in 27 (87.1%) cases. Concurrent coloration in the pelvic lymphatic vessels was also observed in 22of the 27 patients. The SLNs were identified in 23 of the 27 (85.2%)cases with a lymphatic staining, with a total number of 90 SLNs,and a mean of 3.9 in each case (range, 1-10). Besides one SLN (1.1%)in the para-aortic area, the other 89 (98.9%) were in the nodes of the pelvis. The most dense locations of SLNs included obturator in 38 (42.2%) and interiliac in 19 (21.1%) cases. In our group, pelvic lymphadenectomy was conducted in 27 (87.1%) patients and pelvic nodal sampling in 4 (12.9%). Of the 31 cases, a concurrent abdominal para-aortic lymph node sampling was conducted in 7. A total of 926 nodes were harvested, with an average of 39.8 in each case (range, 14-55). Nodal metastases occurred in 3 patients (9.7%), 2 of them with SLN involvement and the other without SLN involvement. Adverse reactions or injury related to the study was not found.CONCLUSION Application of methylene blue dye is feasible in an intra
