    Demersal Seining is an active fishing method applying two long seine ropes and a seine net. Demersal seining relies on fish responding to the seine rope as it moves during the fishing process. The seine ropes and net are deployed in a specific pattern encircling an area on the seabed. In some variants of demersal seining the haul-in procedure includes a towing phase where the fishing vessel moves forward before starting to winch in the seine ropes. The initial seine rope encircled area, the gradual change in it during the haul-in process and the fish's reaction to the moving seine ropes play an important role in the catch performance of demersal seine fishing. The current study investigates this subject by applying computer simulation models for demersal seine fishing. The demersal seine fishing is dynamic in nature and therefore a dynamic model, SeineSolver is applied for simulating the physical behaviour of the seine ropes during the fishing process. Information about the seine rope behaviour is used as input to another simulation tool, SeineFish that predicts the catch performance of the demersal seine fishing process. SeineFish implements a simple model for how fish at the seabed reacts to an approaching seine rope. Here, the SeineSolver and SeineFish tools are applied to investigate catching performance for a Norwegian demersal seine fishery targeting cod (Gadus morhua) in the coastal zone. The effect of seine rope layout pattern and the duration of the towing phase are investigated. Among the four different layout patterns investigated, the square layout pattern was predicted to perform best; catching 69%-86% more fish than would be obtained with the rectangular layout pattern. Inclusion of a towing phase in the fishing process was found to increase the catch performance for all layout patterns. For the square layout pattern, inclusion of a towing phase of 15 or 35 minutes increased the catch performance by respectively 37% and 48% compared to fishing without

    The nodal status is the strongest prognostic factor in early stage cancers. The sentinel-lymph node (S.L.N.) is defined as the first draining lymph node of an organ; the lymph node status is determined by the histological results of S.L.N.. The lymphadenectomy, with high morbidity, is realised only in case of metastatic S.L.N.. The S.L.N. identification, in most of cases, is performed using the combination of blue dye and radiocolloid {sup 99m}Tc injections. The purpose of this article is to give some practical details about the S.L.N. isotopic procedure in breast cancer, vulva and penile cancer, uterine cervix and prostate cancer. (author)

    Osteogenesis imperfecta (OI) is a rare bone disorder. In 90% of cases, OI is caused by mutations in the COL1A1/2 genes, which code procollagen α1 and α2 chains. The main aim of the current research was to identify the mutational spectrum of COL1A1/2 genes in Estonian patients. The small population size of Estonia provides a unique chance to explore the collagen I mutational profile of 100% of OI families in the country. We performed mutational analysis of peripheral blood gDNA of 30 unrelated Estonian OI patients using Sanger sequencing of COL1A1 and COL1A2 genes, including all intron-exon junctions and 5'UTR and 3'UTR regions, to identify causative OI mutations. We identified COL1A1/2 mutations in 86.67% of patients (26/30). 76.92% of discovered mutations were located in the COL1A1 (n = 20) and 23.08% in the COL1A2 (n = 6) gene. Half of the COL1A1/2 mutations appeared to be novel. The percentage of quantitative COL1A1/2 mutations was 69.23%. Glycine substitution with serine was the most prevalent among missense mutations. All qualitative mutations were situated in the chain domain of pro-α1/2 chains. Our study shows that among the Estonian OI population, the range of collagen I mutations is quite high, which agrees with other described OI cohorts of Northern Europe. The Estonian OI cohort differs due to the high number of quantitative variants and simple missense variants, which are mostly Gly to Ser substitutions and do not extend the chain domain of COL1A1/2 products.

    Aim: To analyze COL1A1/2 mutations in prenatal-onset OI for determine the proportion of mutations in type I collagen genes among prenatal onset OI and to provide additional data for genotype-phenotype analyses. Material and Methods: Ten cases of severe fetal short-limb dwarfism detected by antenatal ultrasonography were referred to our center. Before the termination of pregnancy, cordocentesis was performed for fetal karyotype and COL1A1/2 gene sequencing analysis. Postmortem radiographic examination was performed at all instances for definitive diagnosis. Results: COL1A1 and COL1A2 SNP and mutations were identified in all the cases. Among these, one synonymous SNP and four synonymous SNPs were recognized in COL1A1/2, respectively, seven cases have distinct heterozygous mutations and six new COL1A1/2 gene mutations were identified. Conclusion: There has been substantial progress in the identification of the molecular defects responsible for skeletal dysplasias. With the constant increase in the number of identified mutations in COL1A1 and COL1A2, genotype-phenotype correlation is becoming increasingly pertinent. © 2015 S. Karger AG, Basel.

    The first reported application of uterine artery embolization, in 1979, was to treat life-threatening hemorrhage after a failed hysterectomy. Since then, uterine artery embolization has been used very successfully to control acute or delayed post-partum hemorrhage, post-surgical hemorrhage and hemorrhage from ectopic pregnancy, to treat uterine arteriovenous malformations and as prophylaxis before high-risk surgery, such as cesarean delivery in women with placenta previa. In contrast to these proven but underutilized applications, uterine embolization for fibroids has, in a short time, achieved significant notice in the lay press and is being widely offered. Ravina and colleagues, first reported uterine fibroid shrinkage after embolization for the treatment of acute bleeding. Since then, his group has performed over 100 procedures with up to a 6-year follow-up. The cumulative clinical success rate for the treatment of abnormal uterine bleeding due to fibroids is reported to be approximately 85% and for treatment of pain or pressure symptoms, about 75%. Six-month follow-up sonography reveals an average reduction of fibroid size of approximately 40%. However, to date, no studies have compared patients who undergo embolization with a nontreatment cohort or with surgical intervention. (author)

    The genetics of osteogenesis imperfecta (OI) have not been studied in a Vietnamese population before. We performed mutational analysis of the COL1A1 and COL1A2 genes in 91 unrelated OI patients of Vietnamese origin. We then systematically characterized the mutation profiles of these two genes which are most commonly related to OI. Genomic DNA was extracted from EDTA-preserved blood according to standard high-salt extraction methods. Sequence analysis and pathogenic variant identification was performed with Mutation Surveyor DNA variant analysis software. Prediction of the pathogenicity of mutations was conducted using Alamut Visual software. The presence of variants was checked against Dalgleish's osteogenesis imperfecta mutation database. The sample consisted of 91 unrelated osteogenesis imperfecta patients. We identified 54 patients with COL1A1/2 pathogenic variants; 33 with COL1A1 and 21 with COL1A2. Two patients had multiple pathogenic variants. Seventeen novel COL1A1 and 10 novel COL1A2 variants were identified. The majority of identified COL1A1/2 pathogenic variants occurred in a glycine substitution (36/56, 64.3 %), usually serine (23/36, 63.9 %). We found two pathogenic variants of the COL1A1 gene c.2461G > A (p.Gly821Ser) in four unrelated patients and one, c.2005G > A (p.Ala669Thr), in two unrelated patients. Our data showed a lower number of collagen OI pathogenic variants in Vietnamese patients compared to reported rates for Asian populations. The OI mutational profile of the Vietnamese population is unique and related to the presence of a high number of recessive mutations in non-collagenous OI genes. Further analysis of OI patients negative for collagen mutations, is required.

    Full Text Available Purpose. Justification and calculation of a new methodological approach to the construction of a standard beach seine (502 / 302 х 3.75 with the use of the properties of mirror netting ensuring the saving of the netting material, reduction of weight, price and drag resistance. Methodology. The carp age group selectivity of the constructed seine was assessed within fish fauna monitoring based on the catch analysis of monitoring gill nets with mesh sizes of 30-130 mm according to generally accepted methods [9, 10]. Calculation of netting materials and ropes was carried out according to generally accepted methods [12-14]. Seine resistance was calculated according to N. T. Senin formula for different netting materials and the angles of the movement of different seine parts in water [2]. The gear reliability and data processing were carried out according to standard methods [11, 14, 15]. Findings. A variant of the construction of the maximum lightweight beach lake seines made of mirror pattern netting taking into account the properties of the mirror pattern netting material, reduction of weight, price and drag resistance has been proposed. The provided recalculation of the properties of a serial seine made of rhombic mesh for the mirror netting seine taking into account netting properties allowed: 1 reducing the seine drag resistance value by 1,4 times; 2 reducing the weight of netting materials by 16.3% compared to the prototype; 3 increasing the seine selectivity when fishing older age groups of carp in non-drainable ponds. Originality. We presented the method of the calculation and construction of lake beach seines made of mirror netting, analyzed the technological stages of the construction of mirror netting, determined main qualitative and technological parameters, which had effect on the conditions of the construction and reliability of such fishing gears. A new method of the use of an insert of the combined netting material cutting ensuring

    Introduction Le cancer du sein représente un problème de santé publique au Maroc. L’objectif de ce travail était d’estimer le taux de survie au cancer du sein chez les patientes habitant la ville de Rabat. Méthodes Etude pronostique réalisée chez les patientes diagnostiquées pour cancer du sein de 2005 à 2008, habitant la ville de Rabat et enregistrées au registre des cancers de Rabat. La date d’inclusion dans l’étude correspondait à la date de confirmation histologique du cancer. L’estimation de la survie a été réalisée par la méthode de Kaplan Meier, et la comparaison entre les différentes classes d’une variable a été réalisée par le test de log rank. L’étude des facteurs associés à la survie a été effectuée par le modèle de Cox. Résultats Durant la période d’étude 628 cas de cancer du sein ont été collectés. Le pourcentage de décès était de 19,9%. La survie globale à un an était de 97,1%, elle était de 89,2% à 3 ans et de 80,6 % à 5 ans. En analyse multivariée la survie au cancer du sein était statistiquement moins bonne chez les patientes âgées de plus de 70 ans (p<0,001), ayantune grande taille de tumeur (p<0,001), un stade avancé d’adénopathies (p=0,007), présentant des métastases (p<0,001) et non traitées par hormonothérapie (p=0,002). Conclusion Une grande taille de la tumeur et la présence de métastases sont des facteurs de mauvais pronostic du cancer du sein d’où la nécessité de renforcer les programmes de dépistage.

    To categorize the anatomic variants of uterine arteries, and determine the incidence of menopausal symptoms where the tubo-ovarian branches were seen prior to embolization. Between July 1997 and June 2000, 257 (n = 257) uterine fibroid embolizations were performed at our institution. Arteriograms were retrospectively evaluated. Uterine arteries were classified into groups: type I (the uterine artery as first branch of the inferior gluteal artery), type II (the uterine artery as second or third branch of the inferior gluteal artery), type III (the uterine artery, the inferior gluteal and the superior gluteal arteries arising as a trifurcation), type IV (the uterine artery as first branch of the hypogastric artery), inconclusive, or not studied. Tubo-ovarian branches were recorded if visualized prior to and/or after embolization. Menopausal symptoms were recorded (n = 175 at 3 months, n = 139 at 6 months, n = 98 at 1 year, n = 22 at 2 years) using written questionnaires. Five hundred and fourteen uterine arteries (n = 514) were evaluated. There were 38% classifiable types, 23% inconclusive, and 39% not studied. Classification was as follows: type I, 45%; type II, 6%; type III, 43%; type IV, 6%. Among 256 patients, tubo-ovarian arteries were seen in 36 prior to embolization, but not afterwards. In this group, 25 patients reported transient menopausal symptoms (hot flashes, amenorrhea). Five patients did not report any menopausal symptoms. Six patients did not answer the questionnaires. Type I is the most common type of anatomy, followed by type III. The tubo-ovarian arteries may be visualized prior to and/or after embolization. The embolization was monitored to avoid embolization of the tubo-ovarian branches. Menopausal symptoms were transient all patients when the tubo-ovarian branches were seen prior to embolization

Methods: Uterine arterial embolization with PLE was performed in 25 patients. The improvement of symptoms and uterine size changes were followed up in 3-18 months(mean 6 months) after the procedure. Results: All but 2 cases were successfully treated bilaterally. Super-selective angiography showed enlargement of uterine artery, accompanied by tortuous branches. The uterine size was increased. The uterus itself was significantly stained and emptied slowly. Coagulation necrosis was found in resected fibroids after embolization in 3 patients. One month after the procedure, a mean 40% reduction of uterine volume was obtained in 18 followed-up cases. The clinical symptoms were relieved significantly. The main side effects were hypogastric pain(13/25),which was intense in 6 cases. Conclusion: Uterine arterial embolization with PLE is a good non-surgical therapy in symptomatic uterine fibroids with mild side effects

    Objective: To evaluate uterine artery embolization in treating uterine scar pregnancy. Methods: During the period from November 2007 to February 2010, 11 patients with uterine scar pregnancy were encountered in authors' hospital. All the patients had a history of lower uterine segment cesarean section. Four patients had to receive an emergency uterine artery embolization due to acute massive vaginal bleeding. The other 7 patients received intravenous chemotherapy with MTX (0.4 mg/kg/day, every 5 days as a treatment course). Emergency uterine artery embolization had to be carried out in three patients as they developed acute massive vaginal bleeding (blood loss ≥ 100 ml/hour) during the course of chemotherapy, while subsequent uterine artery embolization was performed in the remaining 4 patients after they had completed two courses of treatment when their blood HCG showed no significant decrease. The clinical results were analyzed. Results: Remarkable decrease in serum HCG was seen in all 11 patients after interventional management. The vaginal bleeding in 7 patients was significantly reduced within half an hour after uterine artery embolization. The uterus together with intact fertility was successfully preserved in all 11 patients. Conclusion: For the treatment of uterine scar pregnancy complicated by massive vaginal bleeding (blood loss ≥ 500 ml/24 h) and/or abnormal elevation of serum HCG (blood β-HCG ≥ 20000 IU/L), ectopic pregnancy with the mass diameter ≥ 5 cm, uterine artery embolization treatment is very safe and effective. This technique can well preserve female patient's uterus and fertility ability. It is of value to employ this treatment in clinical practice. (authors)

    Objective: To discuss the feasibility and safety of uterine artery embolization(UAE) for the treatment of symptomatic uterine leiomyomas. Methods: During the period of Jan. 2005-June 2009, UAE was performed in 85 patients with uterine leiomyomas in the authors' hospital. The main symptoms included hypermenorrhea, delayed menstruation and pelvic pressure symptoms. The bilateral uterine arteries were embolized with polyvinyl alcohol particles (diameter 500-710 μm) and Gelfoam. The technical success rate and the clinical results were observed. The patients were followed up for 6-36 months. Results: The technical success rate of bilateral uterine artery embolization was 100%. No serious complications occurred. During the follow-up period, menses returned to regular cycle in all patients and the hemoglobin concentration rose up to normal level in patients with anemia. The sizes of uterine leiomyomas were decreased by 57.5% after 6 months of the procedure. Conclusion: UAE is an effective and less-invasive treatment for symptomatic uterine leiomyomas with reliable results and fewer complications. This technique can greatly avoid unnecessary uterectomy and, thus, preserve the fertility of the female patients.(authors)

    To demonstrate surgical techniques utilized during uterine-sparing laparoscopic resections of accessory cavitated uterine masses (ACUMs). ACUMs represent a rare uterine entity observed in premenopausal women suffering from dysmenorrhea and recurrent pelvic pain. The diagnosis is made when an isolated extra-cavitated uterine mass is resected from an otherwise normal appearing uterus with unremarkable endometrial lumen and adnexal structures. Pathologic confirmation requires an accessory cavity lined with endometrial epithelium (and corresponding glands and stroma) filled with chocolate-brown fluid. Adenomyosis must be absent. Although the origin of ACUMs is currently unknown, the most common presentation is a 2-4 cm lateral uterine wall mass at the level of the insertion of the round ligament. Hence it has been hypothesized that gubernaculum dysfunction may be responsible for duplication or persistence of paramesonephric tissue leading to ACUM formation as a new Müllerian anomaly. A stepwise surgical tutorial describing 2 laparoscopic ACUM resections using a narrated video (Canadian Task Force classification III). An academic tertiary care hospital. In this video, we present 2 patients who underwent uterine-sparing laparoscopic resections of their ACUM in order to preserve fertility (Case 1) or avoid the complications and surgical recovery time of a total laparoscopic hysterectomy (Case 2). Case 1 is a 19-year-old, gravida 0, para 0 woman with dysmenorrhea and recurrent pelvic pain who presented for multiple emergency room and outpatient evaluations. Transvaginal ultrasonography was unremarkable except for a 28×30×26mm left lateral uterine mass with peripheral vascular flow that was initially felt to be a leiomyoma or rudimentary uterine horn. MRI imaging, however, demonstrated this mass to be more consistent with an ACUM. This was based on the lack of communication between the lesion and the main uterine cavity exhibited by high T2 signal (compatible with

    Full Text Available Introduction. Uterine artery embolization (UAE is a minimally invasive intervention that is used in the treatment of fibroids. UAE can lead to complications including postembolization syndrome, postprocedure pain, infection, endometrial atrophy leading to secondary amenorrhea, and uterine necrosis. Uterine necrosis after UAE is very rare and hence poses a clinical dilemma for any clinician in its identification and management. We document a case of uterine necrosis after UAE and conduct a literature review on its causation, clinical features, and management principles. Case. A patient presented one month after UAE with abdominal pain and abdominal vaginal discharge. Her work-up revealed features of possible uterine necrosis with sepsis and she was scheduled for a laparotomy and a subtotal hysterectomy was performed. She was subsequently managed with broad spectrum antibiotic and recovered well. Conclusion. Uterine necrosis after UAE is a rare occurrence and we hope the documentation of this case will add to the body of knowledge around it. Theories that explain its occurrence include the use of small particles at embolization, the use of Contour-SE a spherical poly-vinyl alcohol, and lack of collateral supply to the uterus. Its symptoms may be nonspecific but unremitting abdominal pain is invariably present. Finally although conservative management may be successful at times, surgical management with hysterectomy will be required in some cases. The prognosis is good after diagnosis and surgical management.

    2008-01-01

    Objective: To study the efficacy of treating different types of uterine adenomyosis with transcatheter local infusion of methotrexate (MTX) combined with uterine arterial embolization under guidance of digital subtraction angiography (DSA). Methods: 33 cases were primarily screened out according to clinical symptoms and color Doppler and then further diagnosis as diffuse or local adenomyosis were undertaken with super selective uterine arterial angiography. The patients were then treated with uterine arterial local infusion (50 mg MTX)and embolization with PVA microsphere (diameter 450-650 μm), individually. Finally, the comparison between the preoperative and postoperative menstruation volumes, the degrees of dysmenorrheal, uterine sizes and the levels of sexual hormones of diffuse and local adenomyosis was carried out. Results: The uterine arterial local infusion of MTX combined with embolization showed no chemotherapeutic side effects. In all cases, there were decrease of menstruation amount, alleviated dysmenorrhea, reduction of uterine size, and the efficacy was more evident in diffuse adenomyosis (P<0.05). Conclusions: Micro-invasive interventional technique combined with drug therapy is promising for diffuse and local adenomyosis especially for the former. (authors)

    2012-01-01

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

    We aimed to evaluate the performance of a non-invasive EMG electrical uterine monitor (EUM) versus tocodynamometry (TOCO) by comparing both to internal uterine pressure catheter (IUPC). Prospective observational trial. Uterine activity was recorded continuously and simultaneously, in women during active term labor, with TOCO, EUM and IUPC. Uterine activity tracings were analyzed by three blinded physicians. Overall, 385 tracings from 43 women were analyzed. A similar rate of interpretable tracings between physicians was demonstrated for EUM (87%; 95% CI 80.9-92.7%) and IUPC (94.8%; 95% CI 83.4-96.3%), with a significantly lower rate for TOCO (67.5%; 95% CI 59.4-76.8%, p TOCO versus IUPC (-3.34 ± 4.97). There is a high variability between the timing of TOCO contractions as compared to IUPC (4.74 ± 10.03 seconds), while a gap of 8.46 ± 4.24 seconds was detected for EUM. The sensitivity, positive predictive value and false positive rate for individual contraction identification by TOCO and EUM are 54.0%, 84.4%, 15.6% and 94.2%, 87.6%, 12.4%, respectively. EUM is efficient as IUPC for uterine activity assessment and both techniques are superior in comparison to external tocodynamometry. Our results support the use of non-invasive EMG technology to monitor uterine activity.

    Cultural heritage parchments made from the reticular dermis of animals have been subject to studies of deterioration and conservation by amino acid analysis. The reticular dermis contains a varying mixture of collagen I and III (COL I and III). When dealing with the results of the amino acid...... analyses, till now the COL III content has not been taken into account. Based on the available amino acid sequences we present a method for determining the amount of COL III in the reticular dermis of new and historical parchments calculated from the ratio of Ile/Val. We find COL III contents between 7...... and 32 % in new parchments and between 0.2 and 40 % in the historical parchments. This is consistent with results in the literature. The varying content of COL III has a significant influence on the uncertainty of the amino acid analysis. Although we have not found a simple correlation between the COL...

    Taylor, Jesse; Unsoeld, Thomas; Hutter, Harald

    2018-06-01

    We have identified the transmembrane collagen, COL-99, in a genetic screen for novel genes involved in axon guidance in the nematode C. elegans. COL-99 is similar to transmembrane collagens type XIII, XXIII and XXV in vertebrates. col-99 mutants exhibit guidance defects in axons extending along the major longitudinal axon tracts, most prominently the left ventral nerve cord (VNC). COL-99 is expressed in the hypodermis during the time of axon outgrowth. We provide evidence that a furin cleavage site in COL-99 is essential for function, suggesting that COL-99 is released from the cells producing it. Vertebrate homologs of COL-99 have been shown to be expressed in mammalian nervous systems and linked to various neurological disease but have not been associated with guidance of extending neurons. col-99 acts genetically with the discoidin domain receptors ddr-1 and ddr-2, which are expressed by neurons affected in col-99 mutants. Discoidin domain receptors are activated by collagens in vertebrates. DDR-1 and DDR-2 may function as receptors for COL-99. Our results establish a novel role for a transmembrane collagen in axonal guidance and asymmetry establishment of the VNC. Copyright © 2018 Elsevier Inc. All rights reserved.

    Fibrillar collagens are well known for their links to human diseases, with which all have been associated except for the two most recently identified fibrillar collagens, type XXIV collagen and type XXVII collagen. To assess functions and potential disease phenotypes of type XXVII collagen, we examined its roles in zebrafish embryonic and post-embryonic development. We identified two type XXVII collagen genes in zebrafish, col27a1a and col27a1b. Both col27a1a and col27a1b were expressed in notochord and cartilage in the embryo and early larva. To determine sites of type XXVII collagen function, col27a1a and col27a1b were knocked down using morpholino antisense oligonucleotides. Knockdown of col27a1a singly or in conjunction with col27a1b resulted in curvature of the notochord at early stages and formation of scoliotic curves as well as dysmorphic vertebrae at later stages. These defects were accompanied by abnormal distributions of cells and protein localization in the notochord, as visualized by transmission electron microscopy, as well as delayed vertebral mineralization as detected histologically. Together, our findings indicate a key role for type XXVII collagen in notochord morphogenesis and axial skeletogenesis and suggest a possible human disease phenotype.

    Mutations in collagen, type IV, alpha 1 (COL4A1), a major component of basement membranes, cause multisystem disorders in humans and mice. In the eye, these include anterior segment dysgenesis, optic nerve hypoplasia and retinal vascular tortuosity. Here we investigate the retinal pathology in mice carrying dominant-negative Col4a1 mutations. To this end, we examined retinas longitudinally in vivo using fluorescein angiography, funduscopy and optical coherence tomography. We assessed retinal function by electroretinography and studied the retinal ultrastructural pathology. Retinal examinations revealed serous chorioretinopathy, retinal hemorrhages, fibrosis or signs of pathogenic angiogenesis with chorioretinal anastomosis in up to approximately 90% of Col4a1 mutant eyes depending on age and the specific mutation. To identify the cell-type responsible for pathogenesis we generated a conditional Col4a1 mutation and determined that primary vascular defects underlie Col4a1-associated retinopathy. We also found focal activation of Müller cells and increased expression of pro-angiogenic factors in retinas from Col4a1(+/Δex41)mice. Together, our findings suggest that patients with COL4A1 and COL4A2 mutations may be at elevated risk of retinal hemorrhages and that retinal examinations may be useful for identifying patients with COL4A1 and COL4A2 mutations who are also at elevated risk of hemorrhagic strokes.

    Uterine rupture is a potential life-threatening complication during a trial of labor after cesarean delivery. Single-layer closure of the uterus at cesarean delivery has been associated with an increased risk of uterine rupture compared with double-layer closure. Lower uterine segment thickness measurement by ultrasound has been used to evaluate the quality of the uterine scar after cesarean delivery and is associated with the risk of uterine rupture. To estimate the impact of previous uterine closure on lower uterine segment thickness. Women with a previous single low-transverse cesarean delivery were recruited at 34-38 weeks' gestation. Transabdominal and transvaginal ultrasound evaluation of the lower uterine segment thickness was performed by a sonographer blinded to clinical data. Previous operative reports were reviewed to obtain the type of previous uterine closure. Third-trimester lower uterine segment thickness at the next pregnancy was compared according to the number of layers sutured and according to the type of thread for uterine closure, using weighted mean differences and multivariate logistic regression analyses. Of 1613 women recruited, with operative reports available, 495 (31%) had a single-layer and 1118 (69%) had a double-layer closure. The mean third-trimester lower uterine segment thickness was 3.3 ± 1.3 mm and the proportion with lower uterine segment thickness cesarean delivery is associated with a thicker third-trimester lower uterine segment and a reduced risk of lower uterine segment thickness <2.0 mm in the next pregnancy. The type of thread for uterine closure has no significant impact on lower uterine segment thickness. Copyright © 2017 Elsevier Inc. All rights reserved.

  1. Uterine sarcoma Part I—Uterine leiomyosarcoma: The Topic Advisory Group systematic review

    2016-08-01

    Full Text Available Uterine sarcomas account for 3–7% of all uterine cancers. Because of their rarity, unknown etiology, and highly divergent genetic aberration, there is a lack of consensus on risk factors for occurrence and predictive poor outcomes as well as optimal therapeutic choices. Tumor types according to the World Health Organization classification include leiomyosarcoma, endometrial stroma sarcoma, and undifferentiated sarcoma. Staging is done using the 2014 Federation International Gynecology and Obstetrics and 2010 American Joint Committee on Cancer tumor, lymph node, and metastases systems. Tumor grade can be classified based on the French Federation of Cancer Centers Sarcoma Group system or the Broder’s system that incorporates tumor differentiation, mitotic count, and tumor necrosis. This review is a series of articles discussing uterine sarcoma, and this is Part I, which focuses on one of the subtypes of uterine sarcomas—uterine leiomyosarcoma. The clinical characteristics, diagnosis, outcome, and recent advances are summarized in this article.

  3. Primary uterine inertia in four labrador bitches.

    Davidson, Autumn P

    2011-01-01

    Uterine inertia is a common cause of dystocia in the bitch and is designated as primary (i.e., uterine contractions fail to ever be initiated) or secondary (i.e., uterine contractions cease after a period of time but before labor is completed). The etiology of primary uterine inertia is not well understood. The accurate diagnosis of primary uterine inertia requires the use of tocodynamometry (uterine monitoring). Primary uterine inertia has been postulated to result from a failure of luteolysis resulting in persistently elevated progesterone concentrations. In this study, primary uterine inertia was diagnosed in a series of four bitches in which luteolysis was documented suggesting some other etiopathogenesis for primary uterine inertia.

  4. Precision and relative effectiveness of a purse seine for sampling age-0 river herring in lakes

    Stock assessments for anadromous river herring, collectively Alewife Alosa pseudoharengus and Blueback Herring A. aestivalis, lack adequate demographic information, particularly with respect to early life stages. Although sampling adult river herring is increasingly common throughout their range, currently no standardized, field‐based, analytical methods exist for estimating juvenile abundance in freshwater lakes. The objective of this research was to evaluate the relative effectiveness and sampling precision of a purse seine for estimating densities of age‐0 river herring in freshwater lakes. We used a purse seine to sample age‐0 river herring in June–September 2015 and June–July 2016 in 16 coastal freshwater lakes in the northeastern USA. Sampling effort varied from two seine hauls to more than 50 seine hauls per lake. Catch rates were highest in June and July, and sampling precision was maximized in July. Sampling at night (versus day) in open water (versus littoral areas) was most effective for capturing newly hatched larvae and juveniles up to ca. 100 mm TL. Bootstrap simulation results indicated that sampling precision of CPUE estimates increased with sampling effort, and there was a clear threshold beyond which increased effort resulted in negligible increases in precision. The effort required to produce precise CPUE estimates, as determined by the CV, was dependent on lake size; river herring densities could be estimated with up to 10 purse‐seine hauls (one‐two nights) in a small lake (50 ha). Fish collection techniques using a purse seine as described in this paper are likely to be effective for estimating recruit abundance of river herring in freshwater lakes across their range.

    Objective: To prospectively investigate the clinical application of bilateral uterine arterial embolization with dextran microspheres in treating uterine leiomyomas. Methods: A total of 60 patients with uterine leiomyomas, encountered in the authors' hospital during the period from Jan. 2003 to Dec. 2010, were enrolled in this study. The patients were randomly divided into study group and control group with 30 cases in each group. Patients in the study group received bilateral uterine artery embolization by using dextran microspheres (Sephadex, g-50, 100-300 μm) as embolic agents, while patients in control group received bilateral uterine artery embolization by using KMG (500-700 μm) as embolic agents. Before and after the treatment, all patients were kept under observation for the menstrual flow, the size of the uterine and the leiomyoma and the changes in sex hormone level. The hospitalization costs were recorded. The results were compared between the two groups. Results: The technical success rate of catheterization and embolization procedure was 100% in both groups. After the therapy, the volumes of both the uterine and the leiomyoma were significantly decreased, but no significant difference in the size reduction existed between the two groups (both P.0.05). The clinical symptoms were markedly improved in all patients. The sex hormone level showed no obvious changes. No serious complications occurred. The hospitalization cost of the study group was significantly lower than that of the control group (P<0.05). Conclusion: For the treatment of uterine leiomyomas, uterine artery embolization with dextran microspheres is very effective and safe. Moreover, the hospitalization cost is lower. Therefore, it is of value to use this technique in clinical practice. (authors)

    This study aimed to determine the expression of lactate dehydrogenase (LDH)-A and LDH-D in patients with uterine myoma, cellular leiomyoma (CLM), and uterine sarcoma and to evaluate their prognostic significance. Protein expression levels of LDH-A and LDH-D were determined in tissue samples from 86 patients (26 uterine myoma, 10 CLM, 50 uterine sarcoma) by immunohistochemistry and their associations with clinicopathologic parameters and outcomes were analyzed in patients with uterine sarcoma. The positivity rates for LDH-A and LDH-D were significantly higher in patients with uterine sarcoma compared with those with uterine myoma or CLM (P sarcoma were classified as having uterine leiomyosarcoma (LMS), malignant endometrial stromal sarcoma, and malignant mixed Mullerian tumor, with 5-year overall survival rates of 59%, 71%, and 29%, respectively (P sarcoma. Furthermore, the overexpressions of LDH-A and LDH-D in uterine sarcoma patients may contribute to further understanding of the mechanism of LDH in tumor metabolism in uterine sarcoma. Positive expression of LDH-A in patients with LMS may act as a potential prognostic biomarker in these patients.

    The Seine river watershed (France) is a deeply anthropogenically impacted area, due to the high population density, intense industrial activities and intensive agriculture. The water quality and ecological functioning of the different rivers of the Seine drainage network have been extensively studied during the last fifteen years within the framework of a large French multidisciplinary scientific program (PIREN Seine program). This paper presents a synthesis of the main data gained in the scope of this program concerning the microbiological water contamination of the rivers of the Seine drainage network. The more common indicator of fecal contamination (fecal coliforms) was mainly used; some complementary works used E. coli and intestinal enterococci as alternative fecal indicators. Point sources (outfall of wastewater treatment plants) and non point sources (surface runoff and soil leaching) of fecal pollution to the rivers of the watershed were quantified. Results showed that, at the scale of a large urbanised watershed as the Seine basin, the input of fecal micro-organisms by non-point sources is much lower than the inputs by point sources. However, the local impact of diffuse non-human sources (especially surface runoff of pastured fields) can be of major importance on the microbiological quality of small headwater rivers. Fecal contamination of the main rivers of the Seine watershed (Seine, Marne, Oise rivers) was studied showing high level of microbiological pollution when compared to European guidelines for bathing waters. The strong negative impact of treated wastewater effluents outfall on the microbiological quality of receiving rivers was observed in different areas of the watershed. Once released in rivers, culturable fecal bacteria disappeared relatively rapidly due to mortality (protozoan grazing, lysis) or loss of culturability induced by stress conditions (sunlight effect, nutrient concentration, temperature). Mortality rates of E. coli were studied

    Objective: To evaluate the mid-long term effects of uterine fibroids embolization. Methods: Uterine artery embolization (UAE) was performed in 110 patients with uterine fibroids with follow up of 48-72 months. All the patients were examined with transvaginal color ultrasound. 51 cases were embolized with mixed liquor of lipiodol and pingyangmycin and another 59 cases with polyvinyl alcohol particles (350-700 μm, in diameter). The mid-long term clinical effects, complications, change of serum sexual hormone, pregnancy and delivery after UAE were observed. Results; Bilateral uterine artery embolization was performed in 110 cases with following outcomes in improvements of menorrhagia in 93/94 (98.9%) and the bulked-related symptoms in 26/26 (100%), decrease of the volumes of uterus 51.5% ± 3.1% (t value 2.861, P<0.01) and fibroids 64.2% ± 6.6% (t value 2.664, P<0.01). No statistical differences in serum levels of luteinizing, follicle stimulating hormone and estradiol before and after the uterine artery embolization were found. All events included abdominal pain in 6/110 (5.5%), fever in 90/110 (81.8%), colporrhagia in 95/110 (86.4%), haematuria in 11/110 (10.0%), non-targeted embolization of bladder in 1/110 (0.9%), transient amenorrhea in 3/110 (2.7%), permanent amenorrhea due to ovarian failure in 3/110 (2.7%), failure of embolization in 1/110 (0.9%) and recurrence after uterine fibroids embolization in 4/110 (3.6%). There were 7 times of pregnancies in 5 patients, including 4 times of deliveries in 4 patients, and one patient accepted artificial abortion 3 times, but with no fibroids recurrences or enlargement under ultrasound follow up. Conclusion: The mid-long term effects of uterine fibroids embolization are positive, stable and safe, but with a low recurrence rate slight ovarian functional change and still safe for pregnancy and delivery.

    To determine whether a history of cesarean section was a risk factor for abnormal uterine bleeding in patients with uterine leiomyomas, and to identify other risk factors for this symptom. We analyzed retrospectively, the medical records of patients who underwent hysterectomies due to the presence of uterine leiomyomas during a 6-year period (2009 and 2014) at Etlik Zubeyde Hanim Women's Health Training and Research Hospital, Ankara, Turkey. Uterine leiomyoma was diagnosed based on histopathological examination of hysterectomy specimens. Demographic characteristics, and laboratory and histopathological findings were compared between patients with uterine leiomyoma with and without abnormal uterine bleeding. In total, 501 (57.9%) patients had abnormal uterine bleeding and 364 (42.1%) patients had other symptoms. A history of cesarean section was more common in patients with abnormal uterine bleeding than in those with other symptoms (17.6% versus 9.3%, p=0.001; odds ratio [OR]: 2.1; 95% confidence interval [CI]: 1.4-3.3). The presence of a submucosal leiomyoma (OR: 2.1; 95% CI: 1.5-3.1) and coexistent adenomyosis (OR: 1.6; 95% CI: 1.1-2.4) were also associated with abnormal uterine bleeding. A history of cesarean section was an independent risk factor for abnormal uterine bleeding in patients with uterine leiomyomas; submucosal leiomyoma and coexisting adenomyosis were also independent risk factors.

  11. Geochemistry of dissolved and suspended loads of the Seine River, France: anthropogenic impact, carbonate and silicate weathering

    This study focuses on the chemistry of the Seine river system, one of the major rivers in Europe, and constitutes the first geochemical investigation of both suspended and dissolved loads of this river. The Seine river drains a typical Mesozoic-Cenozoic sedimentary basin: the Paris basin, constituted of limestones mixed or interbedded with terrigenous sediments derived from the paleoreliefs bordering the Mesozoic and Cenozoic seas. In the context of quantifying the global influence of carbonate and silicate weathering on atmospheric CO 2 consumption, the Seine river offers the possibility of examining weathering rates in a flat sedimentary environment, under temperate climatic conditions. One of the major problems associated with the Seine river, as with many temperate rivers, is pollution. We propose, in this paper, 2 approaches in order to correct the dissolved load of the Seine river for anthropogenic inputs and to calculate weathering rates of carbonates and silicates. The first uses the dissolved load of rivers and tries to allocate the different solutes to different sources. A mixing model, based on elemental ratios, is established and solved by an inversion technique. The second approach consists in using the suspended load geochemistry. Under steady state conditions, we show that the geochemistry of suspended sediments makes it possible to estimate the amount of solutes released during the chemical weathering of silicates, and thus to calculate weathering rates of silicates. The total dissolved load of the Seine river at Paris can be decomposed into 2% of solutes derived from natural atmospheric sources, 7% derived from anthropogenic atmospheric sources, 6% derived from agriculture, 3% derived from communal inputs, and 82% of solutes derived from rock weathering. During high floods, the contribution of atmospheric and agriculture inputs predominates. The weathering rate of carbonates is estimated to be 48 t/km 2/yr (25 mm/1000 yr). Only 10% of carbonates

    Full Text Available The purpose of this study was to investigate the effect of dietary lecithin on skeletal muscle gene expression of collagen precursors and enzymes involved in collagen synthesis and degradation. Finisher gilts with an average start weight of 55.9 ± 2.22 kg were fed diets containing either 0, 4, 20 or 80 g/kg soybean lecithin prior to harvest for six weeks and the rectus abdominis muscle gene expression profile was analyzed by quantitative real-time PCR. Lecithin treatment down-regulated Type I (α1 procollagen (COL1A1 and Type III (α1 procollagen (COL3A1 mRNA expression ( p < 0.05, respectively, indicating a decrease in the precursors for collagen synthesis. The α-subunit of prolyl 4-hydroxylase (P4H mRNA expression also tended to be down-regulated ( p = 0.056, indicating a decrease in collagen synthesis. Decreased matrix metalloproteinase-1 (MMP-1 mRNA expression may reflect a positive regulatory response to the reduced collagen synthesis in muscle from the pigs fed lecithin ( p = 0.035. Lecithin had no effect on tissue inhibitor metalloproteinase-1 (TIMP-1, matrix metalloproteinase-13 (MMP-13 and lysyl oxidase mRNA expression. In conclusion, lecithin down-regulated COL1A1 and COL3A1 as well as tended to down-regulate α-subunit P4H expression. However, determination of muscle collagen content and solubility are required to support the gene functions.

    2013-01-01

    Vascular lesions of the uterus are rare; most reported in the literature are arteriovenous malformations (AVMs). Uterine AVMs can be congenital or acquired. In recent years, there has been an increasing number of reports of acquired vascular lesions of the uterus following pregnancy, abortion, cesarean delivery, and curettage. It can be seen from these reports that there is confusion concerning the terminology of uterine vascular lesions. There is also a lack of diagnostic criteria and management guidelines, which has led to an increased number of unnecessary invasive procedures (eg, angiography, uterine artery embolization, hysterectomy for abnormal vaginal bleeding). This article familiarizes readers with various vascular lesions of the uterus and their management. PMID:24340126

    The 2p-COL problem introduced by Walsh, smoothly interpolates between P and NP by mixing together the polynornial 2-coloring problem and the NP complete 3-coloring problem. A natural upper bound on the non colorability of the 2+p-COL problem in min {r-bar 2 /(1 - p)r-bar 3 }, where r-bar 2 and r-bar 3 are the upper bounds on 2-COL and 3-COL thresholds respectively. In this paper we improve this upper-bound for each 0.73 ≤ p 1. This means that for p ≥ 0.73 the 2+p-COL problem does not behave like the 2-COL problem. We use the method developed by Kaporis et al., which combines the concept of legal rigid colorings introduced by Achlioptas and Molloy with the occupancy problem for random allocations of balls into bins.

    Purpose: We have observed significant rates of uterine artery patency after uterine artery embolization (UAE) with nonspherical polyvinyl alcohol (nsPVA) on 6 month follow-up MR scanning. The study aim was to quantitatively assess uterine artery patency after UAE with nsPVA and to assess the effect of continued uterine artery patency on outcomes. Methods: A single centre, retrospective study of 50 patients undergoing bilateral UAE for uterine leiomyomata was undertaken. Pelvic MRI was performed before and 6 months after UAE. All embolizations were performed with nsPVA. Outcome measures included uterine artery patency, uterine and dominant fibroid volume, dominant fibroid percentage infarction, presence of ovarian arterial collaterals, and symptom scores assessed by the Uterine Fibroid Symptom and Quality of Life questionnaire (UFS-QOL). Results: Magnetic resonance angiographic evidence of uterine artery recanalization was demonstrated in 90 % of the patients (64 % bilateral, 26 % unilateral) at 6 months. Eighty percent of all dominant fibroids demonstrated >90 % infarction. The mean percentage reduction in dominant fibroid volume was 35 %. No significant difference was identified between nonpatent, unilateral, and bilateral recanalization of the uterine arteries with regard to percentage dominant fibroid infarction or dominant fibroid volume reduction. The presence of bilaterally or unilaterally patent uterine arteries was not associated with inferior clinical outcomes (symptom score or UFS-QOL scores) at 6 months. Conclusion: The high rates of uterine artery patency challenge the current paradigm that nsPVA is a permanent embolic agent and that permanent uterine artery occlusion is necessary to optimally treat uterine fibroids. Despite high rates of uterine artery recanalization in this cohort, satisfactory fibroid infarction rates and UFS-QOL scores were achieved

    Full Text Available Abstract Collagen VI myopathies, caused by mutations in the genes encoding collagen type VI (ColVI, represent a clinical continuum with Ullrich congenital muscular dystrophy (UCMD and Bethlem myopathy (BM at each end of the spectrum, and less well-defined intermediate phenotypes in between. ColVI myopathies also share common features with other disorders associated with prominent muscle contractures, making differential diagnosis difficult. This group of disorders, under-recognized for a long time, has aroused much interest over the past decade, with important advances made in understanding its molecular pathogenesis. Indeed, numerous mutations have now been reported in the COL6A1, COL6A2 and COL6A3 genes, a large proportion of which are de novo and exert dominant-negative effects. Genotype-phenotype correlations have also started to emerge, which reflect the various pathogenic mechanisms at play in these disorders: dominant de novo exon splicing that enables the synthesis and secretion of mutant tetramers and homozygous nonsense mutations that lead to premature termination of translation and complete loss of function are associated with early-onset, severe phenotypes. In this review, we present the current state of diagnosis and research in the field of ColVI myopathies. The past decade has provided significant advances, with the identification of altered cellular functions in animal models of ColVI myopathies and in patient samples. In particular, mitochondrial dysfunction and a defect in the autophagic clearance system of skeletal muscle have recently been reported, thereby opening potential therapeutic avenues.

    Four women with symptomatic uterine fibroids were treated by uterine artery embolization (UAE). In all cases both uterine arteries were embolized via a single femoral puncture with polyvinyl alcohol using a selective catheter technique. In three cases, the ovarian artery was not visible on the initial angiogram before embolization, but appeared after the second uterine artery had been treated. In one case of clinical failure following UAE, a repeat angiogram demonstrated filling of the fibroids from the ovarian artery. Anastomoses between uterine and ovarian arteries may cause problems for radiologists performing UAE and are a potential cause of treatment failure

    Species detection error (i.e., imperfect and variable detection probability) is an essential consideration when investigators map distributions and interpret habitat associations. When fish detection error that is due to highly variable instream environments needs to be addressed, sand‐bed streams of the Great Plains represent a unique challenge. We quantified seining detection probability for diminutive Great Plains fishes across a range of sampling conditions in two sand‐bed rivers in Oklahoma. Imperfect detection resulted in underestimates of species occurrence using naïve estimates, particularly for less common fishes. Seining detection probability also varied among fishes and across sampling conditions. We observed a quadratic relationship between water depth and detection probability, in which the exact nature of the relationship was species‐specific and dependent on water clarity. Similarly, the direction of the relationship between water clarity and detection probability was species‐specific and dependent on differences in water depth. The relationship between water temperature and detection probability was also species dependent, where both the magnitude and direction of the relationship varied among fishes. We showed how ignoring detection error confounded an underlying relationship between species occurrence and water depth. Despite imperfect and heterogeneous detection, our results support that determining species absence can be accomplished with two to six spatially replicated seine hauls per 200‐m reach under average sampling conditions; however, required effort would be higher under certain conditions. Detection probability was low for the Arkansas River Shiner Notropis girardi, which is federally listed as threatened, and more than 10 seine hauls per 200‐m reach would be required to assess presence across sampling conditions. Our model allows scientists to estimate sampling effort to confidently assess species occurrence, which

    2014-01-01

    Martin Heidegger’s Sein und Zeit presents one of the most striking reflexions on human facticity, i.e. the fact that Dasein fundamentally exists in a world letting Dasein and world be co-extensive. By quoting two central personages in theology, Pascal and Augustine, Heidegger refers to a concept...... of love that is constitutive for Dasein’s facticity to truth and to knowledge. By investigating the claim that love is as good as absent from Sein und Zeit, the article intends to show that the scanty references to love nevertheless have a central role in Heidegger’s early work and, furthermore, why...... Heidegger returns to it in his later thinking. Interesting in this regard is the connection between the theological concept of love and Heidegger’s concept of ‘world’. The article places Heidegger’s Destruktion of the metaphysical tradition in the realms of his Dasein analysis focussing on facticity. Taking...

    Full Text Available Endometrial stromal tumors are rare uterine tumors (<1%. Four main categories include endometrial stromal nodule, low-grade endometrial stromal sarcoma (LG-ESS, high-grade endometrial stromal sarcoma (HG-ESS, and uterine undifferentiated sarcoma (UUS. This review is a series of articles discussing the uterine sarcomas. LG-ESS, a hormone-dependent tumor harboring chromosomal rearrangement, is an indolent tumor with a favorable prognosis, but characterized by late recurrences even in patients with Stage I disease, suggesting the requirement of a long-term follow-up. Patients with HG-ESS, based on the identification of YWHAE-NUTM2A/B (YWHAE-FAM22A/B gene fusion, typically present with advanced stage diseases and frequently have recurrences, usually within a few years after initial surgery. UUS is, a high-grade sarcoma, extremely rare, lacking a specific line of differentiation, which is a diagnosis of exclusion (the wastebasket category, which fails to fulfill the morphological and immunohistochemical criteria of translocation-positive ESS. Surgery is the main strategy in the management of uterine sarcoma. Due to rarity, complex biological characteristics, and unknown etiology and risk factors of uterine sarcomas, the role of adjuvant therapy is not clear. Only LG-ESS might respond to progestins or aromatase inhibitors.

    Hybrid ColE1 plasmids called ColE1-cos lambda-guaA or ColE1-cos lambda-gal can be efficiently transduced into various E.coli K-12 cells through packaging into lambda phage particles. Using these plasmids, repair of ultraviolet-light (UV) damaged ColE1 DNAs was studied in various UV sensitive E.coli K-12 mutants. The host mutations uvrA and uvrB markedly reduced host-cell reactivation of UV-irradiated ColE1-cos lambda-guaA. Pre-existing hybrid ColE1 plasmids had no effect on the frequency of lambda phage-mediated transduction of another differentially marked hybrid ColE1 DNAs. ColE1-cos lambda-guaA and ColE1-cos lambda-gal DNAs could temporarily but not stably co-exist in E.coli K-12 recA cells. The presence of ColE1-cos lambda-gal in uvrB cells promoted the repair of super-infected UV-irradiated ColE1-cos lambda-guaA about 7-fold. The same ColE1-cos lambda-gal plasmid in a uvrB recA double mutant did not have this promoting effect. These results indicate that the effect of resident hybrid ColE1 plasmids is manifested by the host recA + gene function(s) and suggest that ColE1 plasmit itself provides no recA + -like functions.

    Dani Ejzenberg

    Full Text Available Up to 15% of the reproductive population is infertile, and 3 to 5% of these cases are caused by uterine dysfunction. This abnormality generally leads women to consider surrogacy or adoption. Uterine transplantation, although still experimental, may be an option in these cases. This systematic review will outline the recommendations, surgical aspects, immunosuppressive drugs and reproductive aspects related to experimental uterine transplantation in women.

  10. The transcription factor Lc-Maf participates in Col27a1 regulation during chondrocyte maturation

    The transcription factor Lc-Maf, which is a splice variant of c-Maf, is expressed in cartilage undergoing endochondral ossification and participates in the regulation of type II collagen through a cartilage-specific Col2a1 enhancer element. Type XXVII and type XI collagens are also expressed in cartilage during endochondral ossification, and so enhancer/reporter assays were used to determine whether Lc-Maf could regulate cartilage-specific enhancers from the Col27a1 and Col11a2 genes. The Col27a1 enhancer was upregulated over 4-fold by Lc-Maf, while the Col11a2 enhancer was downregulated slightly. To confirm the results of these reporter assays, rat chondrosarcoma (RCS) cells were transiently transfected with an Lc-Maf expression plasmid, and quantitative RT-PCR was performed to measure the expression of endogenous Col27a1 and Col11a2 genes. Endogenous Col27a1 was upregulated 6-fold by Lc-Maf overexpression, while endogenous Col11a2 was unchanged. Finally, in situ hybridization and immunohistochemistry were performed in the radius and ulna of embryonic day 17 mouse forelimbs undergoing endochondral ossification. Results demonstrated that Lc-Maf and Col27a1 mRNAs are coexpressed in proliferating and prehypertrophic regions, as would be predicted if Lc-Maf regulates Col27a1 expression. Type XXVII collagen protein was also most abundant in prehypertrophic and proliferating chondrocytes. Others have shown that mice that are null for Lc-Maf and c-Maf have expanded hypertrophic regions with reduced ossification and delayed vascularization. Separate studies have indicated that Col27a1 may serve as a scaffold for ossification and vascularization. The work presented here suggests that Lc-Maf may affect the process of endochondral ossification by participating in the regulation of Col27a1 expression.

  11. The ColM Family, Polymorphic Toxins Breaching the Bacterial Cell Wall

    Directory of Open Access Journals (Sweden)

    2018-02-01

    Full Text Available Bacteria host an arsenal of antagonism-mediating molecules to combat for ecologic space. Bacteriocins represent a pivotal group of secreted antibacterial peptides and proteins assisting in this fight, mainly eliminating relatives. Colicin M, a model for peptidoglycan-interfering bacteriocins in Gram-negative bacteria, appears to be part of a set of polymorphic toxins equipped with such a catalytic domain (ColM targeting lipid II. Diversifying recombination has enabled parasitism of different receptors and has also given rise to hybrid bacteriocins in which ColM is associated with another toxin module. Remarkably, ColM toxins have recruited a diverse array of immunity partners, comprising cytoplasmic membrane-associated proteins with different topologies. Together, these findings suggest that different immunity mechanisms have evolved for ColM, in contrast to bacteriocins with nuclease activities.

    1992-01-01

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

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

    Objective: To investigate the causes of amenorrhea after transcatheter uterine artery embolization (TUAE) for uterine fibroids. Methods: Two hundreds thirty-one cases of uterine fibroids with the range of age from 29 to 51 years (mean, 39.5 years) underwent TUAE between April 1999 and May 2004. TUAE was performed by injecting lipiodol-pingyangmycine emulsion (LPE) into bilateral uterine arteries, followed by administration of gelatin sponge particles in 186 of 231 patients. LPE was prepared with pingyangmycine 8-16 mg and ultra fluid lipiodol 6-20 ml. Results: Amenorrhea occurred in 2 of 231 (0.87%) patients respectively at 3 and 4 months after TUAE. Premature ovarian failure was proved to be etiology of amenorrhea in one patient because her serum estradiol (E 2 ) became decreased and serum follicle-stimulating hormone (FSH) level increased. This woman had normal amenorrhea later after receiving estrogen-progestogen sepuential therapy for 12 months. Another patient's amenorrhea was proved to be associated with endometrial atrophy after TUAE by hysteroscope. Conclusion: Amenorrhea caused by premature ovarian failure and endometrial atrophy may occur in a tiny minority of women undergoing TUAE. (authors)

    The aim of our study is to present our experience with uterine restoration after repeated sloughing of uterine fibroids or transvaginal expulsion following uterine artery embolization (UAE) and to determine its safety and outcome. One hundred and twenty-four women (mean age, 40.3 years; age range, 29-52 years) with symptomatic uterine fibroids were included in this retrospective study. We performed arterial embolization with poly(vinyl alcohol) particles (250-710 {mu}m). Clinical symptoms and follow-up information for each patient were obtained through medical records. At an average of 3.5 months (range, 1-8 months) after embolization, magnetic resonance imaging examinations with T1- and T2-weighted and gadolinium-enhanced T1-weighted images were obtained for all patients. The mean follow-up duration was 120 days (90-240 days). Eight (6.5%) patients experienced uterine restoration after repeated sloughing of uterine fibroids or spontaneous transvaginal expulsion. The locations of the leiomyomas were submucosal (n=5), intramural (n=2) and transmural (n=1). The maximum diameter of the fibroids ranged from 3.5 to 18.0 cm, with a mean of 8.4 cm. The time interval from embolization to the uterine restoration was 7-150 days (mean 70.5 days). The clinical symptoms before and during vaginal sloughing or expulsion were lower abdominal pain (n=4), vaginal discharges (n=3), infection of necrotic myomas (n=2) and cramping abdominal pain (n=1). Gentle abdominal compression (n=1) and hysteroscopic assistance (n=1) were required to remove the whole fibroid. No other clinical sequelae, either early or delayed, were documented. Magnetic resonance images revealed the disappearance of leiomyomas, intracavitary rupture resulting in transformation of intramural or transmural myomas into submucosal myomas and localized uterine wall defects. Although the small size of this study precludes a strict conclusion, there appear to be few serious complications directly related to vaginal

    Ana Paula P. Velosa

    2003-06-01

    Full Text Available A cartilagem articular é um tecido altamente especializado, composto por células, os condrócitos, e um conjunto de macromoléculas, como o colágeno e os proteoglicanos. O colágeno é uma proteína fibrilar que garante resistência ao tecido, enquanto os proteoglicanos têm a função de mola biológica, sendo responsáveis pela compressibilidade da cartilagem. A complexa interação entre estas duas proteínas garante a elasticidade. Estas características específicas da cartilagem são essenciais para amortecer as grandes forças de impacto a que as articulações diartrodiais estão submetidas, sem muito gasto de energia, visto tratar-se de um tecido avascular. Em processos artrósicos ocorre um desequilíbrio entre a produção de componentes da matriz extracelular e destruição pelas metaloproteases, levando à degradação e perda do tecido cartilaginoso. A fase inicial da osteoartrose é marcada por perda de fragmentos de proteoglicanos para o líquido sinovial, aumento dos colágenos tipo II e tipo VI, aparecimento dos colágenos I e III, não típicos da cartilagem, e diminuição do colágeno tipo IX, que é importante para manter a integridade da matriz extracelular, além do entumescimento da cartilagem. Como conseqüência, a cartilagem perde suas características específicas, levando a alterações na função articular. A evolução da doença promove diminuição significativa das proteínas, até mesmo do colágeno tipo XI, que tem localização mais interna na estrutura da fibrila heterotípica, e, portanto levando até a exposição do osso. Até o momento, o tratamento da osteoartrose está baseado principalmente no controle da dor e/ou inflamação, não diminuindo ou impedindo a degradação da cartilagem articular. Neste aspecto a perspectiva de tratamento futuro da osteoartrose estaria na utilização de inibidores das metaloproteases associadas a condroprotetores interferindo no "turnover" da cartilagem e

    Uterine polyps can cause abnormal bleeding in women. Conventional practise is to remove them under general anaesthesia but advances in technology have made it possible to perform polypectomy in the office setting. We conducted a patient-preference study to explore women's preferences for treatment setting and to evaluate the effectiveness and treatment experience of women undergoing uterine polypectomy. Three hundred ninety-nine women with abnormal uterine bleeding who were found to have uterine polyps at diagnostic hysteroscopy were recruited. Office polypectomies were performed in office hysteroscopy clinics, and inpatient procedures were undertaken in operating theatres. Three hundred twenty-four of 399 (81 %) expressed a preference for office treatment. There was no difference found between office treatment and inpatient treatment in terms of alleviating abnormal uterine bleeding as assessed by patients and in improving disease-specific quality of life. Acceptability was lower and patient pain scores were significantly higher in the office group. When offered a choice of treatment setting for uterine polypectomy, patients have a preference for office over inpatient treatment. Ambulatory gynaecology services should be available within healthcare systems to meet patient demand.

  3. Abortive phage-infection and UV-protection markers on ColI plasmids from epidemic strains of Salmonella

    Barker, R.M.

    1988-01-01

    Cultures of Escherichia coli carrying ColI plasmids received in conjugation from strains of Salmonella typhimurium and S. agona were examined for abortive infection (Abi) of phage BF23 and for enhanced resistance to the lethal action of UV-irradiation (Uvr). The Abi character of stored cultures of E. coli was also compared with the reaction of the same stock culture tested 5 years before. Seven of the eight potential types differentiated by three characters were represented among 160 ColI plasmids: ColIa Abi + Uvr + (3 plasmids), ColIa Abi - Uvr + (1), ColIa Abi - Uvr-> (2), ColIb Abi + Uvr + (85), ColIb Abi + Uvr - (5), ColIb Abi - Uvr + (4), ColIb Abi-? Uvr - (60). Recognition that different plasmid types could be carried by strains of a clone proved useful in the interpretation of the epidemic spread of strains of S. typhimurium of phage type/biotype 141/9f in Scotland and in tracing the ancestry of a recently emerged rhamnose non-fermenting mutant strain of S. agona.

    Décrire les caractéristiques épidémiologiques et histo-pathologiques des tumeurs malignes du sein au Cameroun. Il s'agissait d'une étude rétrospective descriptive portant sur les tumeurs malignes du sein, colligées, dans les registres des différents laboratoires d'Anatomie Pathologique publiques et privés repartis dans cinq régions (centre, littoral, Ouest, Nord-ouest, Sud-ouest), pendant une période de 10 ans (2004-2013). Les paramètres étudiés étaient la fréquence, l’âge, le sexe, la localisation, le type et le grade histologique, et les récepteurs hormonaux. Un total de 3044 cas de cancers du sein a été recensé, soit une fréquence annuelle de 304,4 cas en moyenne. Le sexe féminin était le plus représenté avec 2971 cas (97,60%) et les hommes avec 73 cas (2,40%), soit un sexe ratio (H/F) de 0,02. L’âge moyen des patients était de 46±15,87 ans, avec des extrêmes de 13 et 95 ans. Selon la localisation, le sein gauche était atteint dans 1244 cas (52%) et le sein droit dans 1115 cas (47%). Au plan histologique, on retrouvait essentiellement des carcinomes avec 96,50% des cas, des sarcomes 1,39%, des lymphomes 1,07% et la maladie de Paget du mamelon, 1,03%. Les tumeurs épithéliales étaient infiltrantes dans 2049 cas (84,46%), avec une prédominance du carcinome canalaire infiltrant (1870 cas) et non infiltrantes dans 377 cas (15,54%). Le grade histo-pronostic de SBR avait révélé une prédominance du grade II dans 66% des cas.

      The aim of this study was to evaluate the efficacy and safety of polypropylene mesh for uterine preservation during pelvic reconstruction in patients with severe uterine prolapse. The study included 67 women with severe uterine prolapse (pelvic organ prolapse quantification stage III/IV) who received transvaginal mesh reconstruction with uterine preservation. Surgery combined with a transobturator membrane sling procedure (tension-free vaginal tape-transobturator route) was performed in 54 patients. Among them, 18 had urodynamic stress incontinence, 30 had occult stress urinary incontinence, and six had mixed urinary incontinence. Objective assessments were carried out with the pelvic organ prolapse quantification staging system, urodynamic examination, and 1-h pad test. Evaluation of urinary and prolapse symptoms comprised the subjective assessment. The mean follow-up interval was 19.6 months (12-40 months). The objective cure rate for the treatment of uterine prolapse was 89.5%, and the objective cure rate for the treatment of urinary incontinence was more than 90%. Uterine preservation in pelvic reconstruction is technically feasible and the subjective and objective assessments imply that uterine preservation in pelvic reconstruction is an alternative option for indicated patients. © 2011 The Authors.

    Uterine leiomyomas are the most common benign tumors of the female urogenital tract. Beside the classic surgical treatment options the minimal-invasive embolization therapy of the leiomyomas increasingly gains importance world-wide. Technique, complications, and results of uterine leiomyoma embolization will be presented. After careful evaluation of indications for embolization the procedure is mostly performed under conscious sedation. A single-sided femoral access route together with cross-over technique generally allows for a flow-directed embolization via both uterine arteries. After embolizing the vessels supplying the tumor, the uterine arteries should be still patent. The success rate of embolization of uterine leiomyomas ranges between 85 and 100%, whereas a reduction in size of the tumors in 42 to 83% and a relief of symptoms in up to 96% can be achieved. The total complication rate is about 10% with mainly ''minor complications''. Worldwide only three deaths following embolization of uterine leiomyomas were reported. The high technical and clinical success rate together with a low complication rate make the embolization of uterine leiomyomas a minimally-invasive alternative to the classic treatment. As long term results are not available indication to embolization of uterine leiomyomas must be carefully established in consensus with gynecologists. (orig.) [de

    Infertility due to the inability of the uterus to carry a pregnancy ranks among the most unresolved issues in reproductive medicine. It affects millions of women worldwide who have congenital or acquired uterine affections, often requiring hysterectomy, and potentially represents a considerable fraction of the general infertile population. Patients suffering from severe uterine infertility are currently compelled to go through gestational surrogacy or adoption; both approaches, unfortunately, deprive them of the maternal experience of pregnancy and birth. Uterine transplantation represents an outstanding, yet complex, perspective to alleviating definitive uterine infertility. In the past decades, a number of scientific experiments conducted both in animals and women, focusing on uterine transplantation, have led to promising results. Collectively, these findings undoubtedly constitute a sound basis to clinically apply uterine transplantation in the near future. This paper is, however, an overview not only of the extent and limitations of accumulated scientific knowledge on uterine transplantation, but also its ethical implications, in an effort to define the actual place of such an approach among the therapeutic arsenal for alleviating infertility. © 2011 New York Academy of Sciences.

    We previously reported that the α-1 chain of type 11 collagen (COL11A1), not normally expressed in the colon, was up-regulated in stromal fibroblasts in most sporadic colorectal carcinomas. Patients with germline mutations in the APC gene show, besides colonic polyposis, symptoms of stromal fibroblast involvement, which could be related to COL11A1 expression. Most colorectal carcinomas are suggested to be a result of an activated Wnt- pathway, most often involving an inactivation of the APC gene or activation of β-catenin. We used normal and polyp tissue samples from one FAP patient and a set of 37 sporadic colorectal carcinomas to find out if the up-regulation of COL11A1 was associated with an active APC/β-catenin pathway. In this study we found a statistically significant difference in COL11A1 expression between normal tissue and adenomas from one FAP patient, and all adenomas gave evidence for an active APC/β-catenin pathway. An active Wnt pathway has been suggested to involve stromal expression of WISP-1. We found a strong correlation between WISP-1 and COL11A1 expression in sporadic carcinomas. Our results suggest that expression of COL11A1 in colorectal tumors could be associated with the APC/β-catenin pathway in FAP and sporadic colorectal cancer

    To assess uterine contractions in early pregnancies using transvaginal color Doppler sonography (TVCDS) and to determine the role of uterine contractions in the diagnosis of early pregnancy failure. 76 patients with abnormal pregnancy diagnosed by sonography or histopathology up to 10 weeks of gestation and 38 normal pregnant women as the control group were examines with TVCDS. The presence of uterine contractions was determined by complete or partial disappearance of the color flow signals of vessels within myometrium, and the direction, amplitude (grade 1-3), and interval of uterine contractions were also evaluated. Uterine contractions were identified in 42 (55.3%) of 76 patients with abnormal pregnancy, whereas they were detected only in 2 (5.3%) of 38 normal pregnant women who had initial grade 1 contraction but disappeared in the follow-up study. In 26 patients with blighted ovum or missed abortion, 15 patients (57.7%),showed uterine contraction of grade 1 in 3 cases, grade 2 in 8 cases, and grade 3 in 4 cases and interval from 45 seconds to 5 minutes. In 30 patients with inevitable or incomplete abortion, 23 patients (76.6%) showed uterine contraction of grade 1 in 2 cases, grade 2 in 9 cases, and grade 3 in 12 cases and interval from 1 to 5 minutes. 4 (20%) of 20 patients with threatened abortion had uterine contraction of grade 2 and interval from 2 to 4 minutes. The presence of uterine contractions was significantly different in abnormal pregnancies compared with that of normal and also among the tree different groups of abnormal pregnancies, but the amplitude did not differ.

    A technique for collecting uterine samples from bitches without the need for surgery was developed. This technique involved visualizing the cervix with a rigid endoscope and passing a catheter through the cervix into the uterus. Samples for microbiology and cytology were obtained by the infusion and aspiration of sterile normal saline. This technique allowed uterine microbiology and cytology of the normal bitch throughout the reproductive cycle. Microorganisms were frequently recovered from the uterus during pro-oestrus and oestrus, but rarely at other stages of the reproductive cycle. The uterine microflora often reflected the vaginal microflora during pro-oestrus and oestrus. The cells found in uterine cytology samples from normal bitches included endometrial epithelial cells, leukocytes, erythrocytes, cervical cells, spermatozoa and bacteria. The types, proportions, morphology and numbers of cells varied throughout the reproductive cycle. The endoscope could be passed into the uterus and the endometrium examined from parturition until day 23 post partum. These procedures and contrast hysterography were used to investigate the reproductive tract of bitches. The above techniques have facilitated the diagnosis of postpartum metritis (n = 3), pyometra (n = 2), endometritis (n = 1), abortion (n = 1), retained placenta (n = 1), postpartum uterine rupture (n = 1), endometrial subinvolution (n = 1) and misalliance (n = 1) in 21 bitches investigated.

    Bisphosphonates are widely used to treat children with osteogenesis imperfecta (OI), a bone fragility disorder that is most often caused by mutations in COL1A1 or COL1A2. However, it is unclear whether this treatment decreases the risk of developing scoliosis. We retrospectively evaluated spine radiographs and charts of 437 patients (227 female) with OI caused by mutations in COL1A1 or COL1A2 and compared the relationship between scoliosis, genotype and bisphosphonate treatment history. At the last follow-up (mean age 11.9 [SD: 5.9] years), 242 (55%) patients had scoliosis. The prevalence of scoliosis was highest in OI type III (89%), followed by OI type IV (61%) and OI type I (36%). Moderate to severe scoliosis (Cobb angle ≥25°) was rare in individuals with COL1A1 haploinsufficiency mutations but was present in about two fifth of patients with triple helical glycine substitutions or C-propeptide mutations. During the first 2 to 4years of bisphosphonate therapy, patients with OI type III had lower Cobb angle progression rates than before bisphosphonate treatment, whereas in OI types I and IV bisphosphonate treatment was not associated with a change in Cobb angle progression rates. At skeletal maturity, the prevalence of scoliosis (Cobb angle >10°) was similar in patients who had started bisphosphonate treatment early in life (before 5.0years of age) and in patients who had started therapy later (after the age of 10.0years) or had never received bisphosphonate therapy. Bisphosphonate treatment decreased progression rate of scoliosis in OI type III but there was no evidence of a positive effect on scoliosis in OI types I and IV. The prevalence of scoliosis at maturity was not influenced by the bisphosphonate treatment history in any OI type. Copyright © 2016 Elsevier Inc. All rights reserved.

    Purpose: In patients with uterine cervical cancer, pretreatment recognition of uterine extension is crucial in treatment decision-making for fertility-sparing surgery and for target delineation in radiotherapy. Although MRI is generally considered the most reliable method, its value for detecting involvement of the uterine internal os is unclear. Methods: Medline, Embase and Cochrane databases were systematically searched (January 1997–December 2012) for MRI studies that measured the accuracy of involvement of the uterine internal os compared to histopathology as reference standard in patients with uterine cervical cancer. Data were assessed using the QUADAS tool. Accuracy concerned either involvement (yes/no) of the uterine internal os, or measuring invasion distance toward the uterine corpus. Results: Two retrospective and two prospective studies described 366 patients diagnosed with uterine cervical cancer FIGO stage IIB or below, in whom 64 (17%) had uterine internal os involvement. For three studies the summary estimates of specificity, sensitivity, negative predictive value (NPV), positive predictive value (PPV), and accuracy were 91%, 97%, 99%, 79% and 95%, respectively; one study had an area under the curve (AUC) of 0.8. Conclusion: MRI has a high level of accuracy; however, data are limited and for validation a large prospective study is needed that compares actual measurements on MRI with histopathological examination.

    1998-12-31

    Excess dissolved plutonium has been measured in the coastal waters of the Channel, from Granville to Boulogne, probably due to sorption-desorption processus. In the Seine estuary, in situ measurements and experimental studies showed that the plutonium desorbs himself from particles in low salinity waters. The desorbed plutonium originates in marine and/or fluvial dissolved Pu. Marine dissolved Pu(V), originating from La Hague plant discharges and from atlantic waters, is reduced and sorbed when the salinity decreases onto estuarial particles: Isotopic Activity Ration {sup 238}Pu/{sup 239}, Pu(IR) of marine dissolved Pu(V) is about 0.7. Fluvial dissolved plutonium originates from atmospheric fallout and from an internal river source: fallout plutonium (IR=0.05) is unreactive with salinity while 45% of river plutonium (IR>1.7) flocculates at 0.5 g l{sup -1}. Desorbed plutonium may have various origins, depending on the Seine liquid discharges and on the tidal coefficient. When the marine waters do not migrate upstream, the low salinity waters encounters particles marked essentially with marine plutonium and the IR of desorbed Pu is about 0.7. The activities of desorbed plutonium are too low to have any influence on the distribution of plutonium in the coastal waters on the Seine Bay. When the marine waters migrate upstream, the low salinity waters meet particles marked essentially with river plutonium (IR>1.7) and desorbed plutonium has a very high IR. These estuarine conditions are encountered five to seven month a year and implicate an increase of the IR of 0.1 of the plutonium present in the coastal waters of the Seine bay (1.2.-1.3.).

    2012-01-01

    Uterine leiomyomas (also called myomata or fibroids) are the most common gynecologic tumors in the United States. The prevalence of leiomyomas is at least 3 to 4 times higher among African American women than in white women. Pathologically, uterine leiomyomas are benign tumors that arise in any part of the uterus under the influence of local growth factors and sex hormones, such as estrogen and progesterone. These common tumors cause significant morbidity for women and they are considered to be the most common indication for hysterectomy in the world; they are also associated with a substantial economic impact on health care systems that amounts to approximately $2.2 billion/year in the United States alone. Uterine myomas cause several reproductive problems such as heavy or abnormal uterine bleeding, pelvic pressure, infertility, and several obstetrical complications including miscarriage and preterm labor. Surgery has traditionally been the gold standard for the treatment of uterine leiomyomas and has typically consisted of either hysterectomy or myomectomy. In recent years, a few clinical trials have evaluated the efficacy of orally administered medications for the management of leiomyoma-related symptoms. In the present review, we will discuss these promising medical treatments in further detail. PMID:22378865

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

    2008-03-01

    Full Text Available Uterine myomas are the most common benign tumors in the female reproductive tract. Most women with myomas are asymptomatic. Therefore, expectant observation and follow-up are often recommended for these myoma patients. However, myomas may cause menstrual symptoms, pelvic pain, pressure complaints, subfer-tility or pregnancy-related complications, with resultant requests for a definitive treatment. The management of myomas has become multidisciplinary in the past 20 years. Basically, the choice of treatment depends on the patient's age, the reason for treatment, the issue of fertility preservation, and the patient's preference. The treatment spectrum includes an expectant management, medical therapy, surgical intervention, uterine artery embolization or ablative techniques. Medical therapy is an option for women with symptomatic myomas who prefer non-surgical treatment, consider fertility preservation, or expect a less aggressive operation after shrinkage of the uterine volume. This review will summarize the recent well-documented drugs for the management of uterine myomas.

    Full Text Available The Seine river watershed is characterized by a high population density and intense agricultural activities. Data show low microbiological water quality in the main rivers (Seine, Marne, Oise of the watershed. Today, there is an increasing pressure from different social groups to restore microbiological water quality in order to both increase the safety of drinking water production and to restore the possible use of these rivers for bathing and rowing activities, as they were in the past. A model, appended to the hydro-ecological SENEQUE/Riverstrahler model describing the functioning of large river systems, was developed to describe the dynamics of faecal coliforms (FC, the most usual faecal contamination indicator. The model is able to calculate the distribution of FC concentrations in the whole drainage network resulting from land use and wastewater management in the watershed. The model was validated by comparing calculated FC concentrations with available field data for some well-documented situations in different river stretches of the Seine drainage network. Once validated, the model was used to test various predictive scenarios, as, for example, the impact of the modifications in wastewater treatment planned at the 2012 horizon in the Seine watershed in the scope of the implementation of the european water framework directive. The model was also used to investigate past situations. In particular, the variations of the microbiological water quality in the Parisian area due to population increase and modifications in wastewater management were estimated over the last century. It was shown that the present standards for bathing and other aquatic recreational activities are not met in the large tributaries upstream from Paris since the middle of the 1950's, and at least since the middle of the XIXth century in the main branch of the Seine river downstream from Paris.

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

    Current status, questions and challenges of transcatheter uterine artery embolization (UAE) in the treatment of uterine fibroids were summarized and analysed. It has been proved that UAE presents a good effectiveness in controlling the symptoms and shrinkage of fibroid and uterine volumes during follow-up of 4 to 6.9 years domestically and abroad, but relapse of the fibroid may however occur in 2 years or longer after UAE. Generally speaking, UAE is safe in the treatment of uterine fibroids but has a possibility of serious complications. UAE has no damage on normal uterine tissues but may affect pregnancy and delivery of patients significantly later on the cause of hypoxia and inertia of uterus. UAE may cause amenorrhea in the minority of women with ovarian failure and endometrium atrophy. The current questions are how to improve long-term efficiency to reduce relapse of tumor and to insure the safety of UAE. It is our further task to exploit more new effective and safe embolic agents by using animal and clinical study on the basic knowledge of pathology, pharmacology, biochemistry, endocrinology and molecular biology.

It shows that the frameshift mutation (D281fs) in the COL9A2 gene is not associated with high myopia in the Han Chinese population, and the two novel variants(c.143G>C and c.884G>A) may contribute to the development of high myopia.

    The aim of this guideline is to provide clinicians with an understanding of the pathophysiology, prevalence, and clinical significance of myomata and the best evidence available on treatment modalities. The areas of clinical practice considered in formulating this guideline were assessment, medical treatments, conservative treatments of myolysis, selective uterine artery occlusion, and surgical alternatives including myomectomy and hysterectomy. The risk-to-benefit ratio must be examined individually by the woman and her health care provider. Implementation of this guideline should optimize the decision-making process of women and their health care providers in proceeding with further investigation or therapy for uterine leiomyomas, having considered the disease process and available treatment options, and reviewed the risks and anticipated benefits. Published literature was retrieved through searches of PubMed, CINAHL, and Cochrane Systematic Reviews in February 2013, using appropriate controlled vocabulary (uterine fibroids, myoma, leiomyoma, myomectomy, myolysis, heavy menstrual bleeding, and menorrhagia) and key words (myoma, leiomyoma, fibroid, myomectomy, uterine artery embolization, hysterectomy, heavy menstrual bleeding, menorrhagia). The reference lists of articles identified were also searched for other relevant publications. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. There were no date limits but results were limited to English or French language materials. Searches were updated on a regular basis and incorporated in the guideline to January 2014. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, and national and international medical specialty societies. The majority of fibroids are asymptomatic and require no intervention or further

    The purpose of this study was to determine whether there is a correlation between large uterine fibroid diameter, uterine volume, number of vials of embolic agent used and risk of complications from uterine artery embolisation (UAE). This was a prospective study involving 121 patients undergoing UAE embolisation for symptomatic uterine fibroids at a single institution. Patients were grouped according to diameter of largest fibroid and uterine volume. Results were also stratified according to the number of vials of embolic agent used and rate of complications. No statistical difference in complication rate was demonstrated between the two groups according to diameter of the largest fibroid (large fibroids were classified as ≥10 cm; Fisher's exact test P = 1.00), and no statistical difference in complication rate was demonstrated according to uterine volume (large uterine volume was defined as ≥750 cm 3 ; Fisher's exact test P = 0.70). 84 of the 121 patients had documentation of the number of vials used during the procedure. Patients were divided into two groups, with ≥4 used defined as a large number of embolic agent. There was no statistical difference between these two groups and no associated increased risk of developing complications. This study showed no increased incidence of complications in women with large-diameter fibroids or uterine volumes as defined. In addition, there was no evidence of increased complications according to quantity of embolic material used. Therefore, UAE should be offered to women with large fibroids and uterine volumes.

    Postpartum haemorrhage (PPH) (bleeding from the genital tract after childbirth) is a major cause of maternal mortality and disability, particularly in under-resourced areas. In these settings, uterotonics are often not accessible. There is a need for simple, inexpensive techniques which can be applied in low-resourced settings to prevent and treat PPH. Uterine massage is recommended as part of the routine active management of the third stage of labour. However, it is not known whether it is effective. If shown to be effective, uterine massage would represent a simple intervention with the potential to have a major effect on PPH and maternal mortality in under-resourced settings. To determine the effectiveness of uterine massage after birth and before or after delivery of the placenta, or both, to reduce postpartum blood loss and associated morbidity and mortality. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 April 2013). All published, unpublished and ongoing randomised controlled trials comparing uterine massage alone or in addition to uterotonics before or after delivery of the placenta, or both, with non-massage. Two researchers independently considered trials for eligibility, assessed risk of bias and extracted the data using the agreed form. Data were checked for accuracy. The effect of uterine massage commenced before or after placental delivery were first assessed separately, and then the combined for an overall result. This review included two randomised controlled trials. The first trial included 200 women who were randomised to receive uterine massage or no massage following delivery of the placenta, after active management of the third stage of labour including use of oxytocin. The numbers of women with blood loss more than 500 mL was small, with no statistically significant difference (risk ratio (RR) 0.52, 95% confidence interval (CI) 0.16 to 1.67). There were no cases of retained placenta in either group. The mean

    DNA fragments obtained from EcoRI endonuclease digestion of bacteriophage ϕ80pt190 (trp+) and the plasmid ColE1 were covalently joined with polynucleotide ligase. Transformation of Escherichia coli trp- strains to tryptophan independence with the recombined DNA selected for reconstituted ColE1 plasmids containing the tryptophan operon and the ϕ80 immunity region. Similarly, an EcoRI endonuclease generated fragment of plasmid pSC105 DNA containing the genetic determinant of kanamycin resistance was inserted into the ColE1 plasmid and recovered in E. coli. The plasmids containing the trp operon (ColE1-trp) and the kanamycin resistance gene were maintained under logarithmic growth conditions at a level of 25-30 copies per cell and accumulate to the extent of several hundred copies per cell in the presence of chloramphenicol. Cells carrying the ColE1-trp plasmid determined the production of highly elevated levels of trp operon-specific mRNA and tryptophan biosynthetic enzymes. Images PMID:4610576

    In this paper, a technique for evaluating uterine peristalsis obtained by magnetic resonance images is proposed. Uterine peristalsis is the wavelike movement of uterine muscle contractions with rhythm and direction. Correlation between direction of uterine peristalsis and menstrual cycle has been reported, which is supposed to help sperm transpotation and implantation. While evaluation of uterine peristalsis has been done, they are very subjective and no quantitative evaluation has been established. In the proposed method the peristalsis area and their contraction intensity were calculated. The points of uterine peristalsis was estimated by the spatio-temporal map, which reflect the time series behavior of the intensities around points set on uterine endometrial boundaries. Then peristalsis area was decided as the estimated points. The contraction intensity was defined as the ratio of the signal intensity change in the peristalsis area. (author)

    To evaluate the effectiveness of the hysteroscopic polypectomy in terms of the decrease of the abnormal uterine bleeding. A cross-sectional and analytical study was done with patients to whom a hysteroscopic polypectomy was done for treating the abnormal uterine bleeding, between January 2009 and December 2013. The response to the treatment was evaluated via a survey given to the patients about the behavior of the abnormal uterine bleeding after the procedure and about overall satisfaction. The results were obtained after a hysteroscopic polypectomy done to 128 patients and were as follows. The average time from the polypectomy applied until the survey was 30.5 months, with a standard deviation of 18 months. 67.2% of the patients reported decreased abnormal uterine bleeding and the 32.8% reported a persistence of symptoms. On average 82.8% of the. patients were satisfied with the treatment. Bivariate and multivariate analysis showed no association between the variables studied and no improvement of abnormal uterine bleeding after surgery (polypectomy). There were no complications. Hysteroscopic polypectomy is a safe surgical treatment, which decreases on two of three patients the abnormal uterine bleeding in the presence of endometrial polyps, with an acceptable level of satisfaction.

    Full text: Introduction: Congenital uterine anomalies are common and usually asymptomatic. The agenesis, malfusion or deficient resorption of the Mullerian canals during embryogenesis may lead to these anomalies. Although ultrasonography (US) is the first step imaging technique in assessment of the uterine pathologies, it can be insufficient in differentiation of them. Magnetic resonance (MR) imaging is an adequate imaging technique in depicting pelvic anatomy and different types of uterine anomalies. Objectives and tasks: In this article, we aimed to present imaging features of the uterine anomalies. Material and methods: Pelvic MR scans of the cases who were referred to our radiology department for suspicious uterine anomaly were evaluated retrospectively. Results: We determined uniconuate uterus (type II), uterus didelphys (type III), bicornuate uterus (type IV), uterine septum (type V) and arcuate uterus (type VI) anomalies according to ASRM (American Society of Reproductive Medicine) classification. Conclusion: In cases with such pathologies leading to obstruction, dysmenorrhea or palpable pelvic mass in the puberty are the main clinical presentations. In cases without obstruction, infertility or multiple abortions can be encountered in reproductive ages. The identification of the subtype of the uterine anomalies is important for the preoperative planning of the management. MR that has multiplanar imaging capability and high soft tissue resolution is a non-invasive and the most important imaging modality for the detection and classification of the uterine anomalies

    Introduction Pancreatic ductal adenocarcinoma (PDA) is a highly lethal disease in which a prominent desmoplastic reaction is a defining characteristic. Fibrillar collagens, such as collagen I and to a lesser extent, collagen III and V comprise the majority of this stromal fibrosis. Type VI collagen (COL6) forms a microfibrillar network associated with type I collagen fibrils. The expression of COL6 has been linked to inflammation and survival. Importantly, tumor-specific alternative splicing in COL6A3 has been identified in several cancers by genome exon arrays. We evaluated the expression and localization of COL6A3 in PDA and premalignant lesions and explored the presence of alternative splicing events. Methods We analyzed paired PDA-normal (n=18), IPMN (n=5), pancreatic cystadenoma (n=5), and eight PDA cell lines with RT-PCR, using unique primers that identify total COL6A3 gene and alternative splicing sites in several of its exons. Western blot analysis and immunohistochemistry were used to analyze the expression levels and localization of COL6A3 protein in the different lesions, and in two animal models of PDA. Results COL6A3 protein levels were significantly upregulated in 77% of the paired PDA-adjacent tissue examined. COL6A3 was mainly present in the desmoplastic stroma of PDA, with high deposition around the malignant ducts and in between the sites of stromal fatty infiltration. Analysis of the COL6A3 splice variants showed tumor-specific consistent inclusion of exons 3 and 6 in 17 of the 18 (94%) paired PDA-adjacent tissues. Inclusion of exon 4 was exclusively tumor-specific, with barely detectable expression in the adjacent tissues. IPMN and pancreatic cystadenomas showed no expression of any of the examined exons. Total COL6A3 mRNA and exon 6 were identified in six PDA cell lines, but only two cell lines (MIA PACA-2 and ASPC-1) expressed exons 3 and 4. In both the xenograft and transgenic models of PDA, COL6A3 immunoreactivity was present in the stroma

    Full Text Available Uterine mesenchymal tumors are a heterogeneous group of neoplasms that can frequently be diagnostically challenging. Differentiation between the benign and malignant counterparts of mesenchymal tumors is significant due to differences in clinical outcome, and the role of the surgical pathologist in making this distinction (especially in the difficult cases cannot be underestimated. Although immunohistochemical stains are supportive toward establishing a final diagnosis, the morphologic features trump all the other ancillary techniques for this group of neoplasms. This review therefore emphasizes the key morphologic features required to diagnose and distinguish uterine mesenchymal tumors from their mimics, with a brief description of the relevant immunohistochemical features.

    Excess dissolved plutonium has been measured in the coastal waters of the Channel, from Granville to Boulogne, probably due to sorption-desorption processus. In the Seine estuary, in situ measurements and experimental studies showed that the plutonium desorbs himself from particles in low salinity waters. The desorbed plutonium originates in marine and/or fluvial dissolved Pu. Marine dissolved Pu(V), originating from La Hague plant discharges and from atlantic waters, is reduced and sorbed when the salinity decreases onto estuarial particles: Isotopic Activity Ration 238 Pu/ 239 , Pu(IR) of marine dissolved Pu(V) is about 0.7. Fluvial dissolved plutonium originates from atmospheric fallout and from an internal river source: fallout plutonium (IR=0.05) is unreactive with salinity while 45% of river plutonium (IR>1.7) flocculates at 0.5 g l -1 . Desorbed plutonium may have various origins, depending on the Seine liquid discharges and on the tidal coefficient. When the marine waters do not migrate upstream, the low salinity waters encounters particles marked essentially with marine plutonium and the IR of desorbed Pu is about 0.7. The activities of desorbed plutonium are too low to have any influence on the distribution of plutonium in the coastal waters on the Seine Bay. When the marine waters migrate upstream, the low salinity waters meet particles marked essentially with river plutonium (IR>1.7) and desorbed plutonium has a very high IR. These estuarine conditions are encountered five to seven month a year and implicate an increase of the IR of 0.1 of the plutonium present in the coastal waters of the Seine bay (1.2.-1.3.). (author)

    Background: Accumulation of 18 F-fluorodeoxyglucose ( 18 F-FDG) in the uterine endometrium and uterine motility are dependent on menstrual cycle. However, the relationship between them remains unknown. Purpose: To investigate the relationship between radiometabolic activity of 18 F-FDG in the uterus and uterine motility observed by cine magnetic resonance imaging (MRI). Material and Methods: The study population consisted of 65 healthy, fertile women, selected from 229 women who underwent positron emission tomography (PET), computed tomography (CT), and MRI for cancer screening at our facility. They were divided into three groups according to their menstrual cycle phases: menstrual, follicular-periovulatory, and luteal. Regions of interest (ROIs) were placed over the endometrium and myometrium to calculate the standardized uptake value (SUV). Uterine peristalsis and contraction shown by cine MR imaging were evaluated visually, and the correlation between FDG uptake and uterine movements was assessed. Results: After excluding nine patients due to inadequate images, 56 patients (19 follicular-periovulatory, 27 luteal, and 10 menstrual) were analyzed. FDG uptake of the endometrium, frequency of peristalsis, and the presence of sustained contraction varied according to the menstruation cycle, with a tendency toward greater uptake in the menstrual phase, but there was little relationship between the frequency of uterine peristalsis and FDG accumulation in the uterus. Significantly higher FDG accumulation in the endometrium was observed in patients with sustained contractions (3.32±1.47) than in those without contractions (2.45±0.66). Conclusion: Our preliminary data suggest that FDG accumulation in the endometrium tends to be higher in patients with uterine contraction, although there was no significant correlation between uterine peristalsis and FDG uptake in the uterine myometrium or endometrium

    Alport syndrome (AS) is a genetically heterogeneous disorder that is characterized by hematuria, progressive renal failure typically resulting in end-stage renal disease, sensorineural hearing loss, and variable ocular abnormalities. Only 15% of cases with AS are autosomal recessive and are caused by mutations in the COL4A3 or COL4A4 genes, encoding type IV collagen. Clinical data in a large consanguineous family with four affected members were reviewed, and genomic DNA was extracted. For mapping, 15 microsatellite markers flanking COL4A3, COL4A4, and COL4A5 in 16 family members were typed. For mutation screening, all coding exons of COL4A3 were polymerase chain reaction- amplified and Sanger-sequenced from genomic DNA. The disease locus was mapped to chromosome 2q36.3, where COL4A3 and COL4A4 reside. Sanger sequencing revealed a novel mis-sense mutation (c.2T>C; p.M1T) in exon 1 of COL4A3. The identified nucleotide change was not found in 100 healthy ethnicity-matched controls via Sanger sequencing. We present a large consanguineous Turkish family with AS that was found to have a COL4A3 mutation as the cause of the disease. Although the relationship between the various genotypes and phenotypes in AS has not been fully elucidated, detailed clinical and molecular analyses are helpful for providing data to be used in genetic counseling. It is important to identify new mutations to clarify their clinical importance, to assess the prognosis of the disease, and to avoid renal biopsy for final diagnosis.

    Full Text Available Percutaneous vascular embolization plays an important role in the management of various gynecologic and obstetric abnormalities. Transcatheter embolization is a minimally invasive alternative procedure to surgery with reduced morbidity and mortality, and preserves the patient's future fertility potential. The clinical indications for transcatheter embolization are much broader and include many benign gynecologic conditions, such as fibroid, adenomyosis, and arteriovenous malformations (AVMs, as well as intractable bleeding due to inoperable advanced-stage malignancies. The most well-known and well-studied indication is uterine fibroid embolization. Uterine artery embolization (UAE may be performed to prevent or treat bleeding associated with various obstetric conditions, including postpartum hemorrhage (PPH, placental implantation abnormality, and ectopic pregnancy. Embolization of the uterine artery or the internal iliac artery also may be performed to control pelvic bleeding due to coagulopathy or iatrogenic injury. This article discusses these gynecologic and obstetric indications for transcatheter embolization and reviews procedural techniques and outcomes.

    Uterine sarcomas comprise a group of rare tumors with differing tumor biology, natural history and response to treatment. Diagnosis is often made following surgery for presumed benign disease. Currently, preoperative imaging does not reliably distinguish between benign leiomyomas and other malignant pathology. Uterine leiomyosarcoma is the most common sarcoma, but other subtypes include endometrial stromal sarcoma (low grade and high grade), undifferentiated uterine sarcoma and adenosarcoma. Clinical trials have shown no definite survival benefit of adjuvant radiotherapy or chemotherapy and have been hampered by the rarity and heterogeneity of these disease types. There is a role of adjuvant treatment in carefully selected cases following multidisciplinary discussion at sarcoma reference centers. In patients with metastatic disease, systemic chemotherapy can then be considered. There is activity of a number of agents, including doxorubicin, trabectedin, gemcitabine-based chemotherapy, eribulin and pazopanib. Patients should be considered for clinical trial entry where possible. Close international collaboration is important to allow progress in this group of diseases.

    Osteogenesis imperfecta (OI) is a heterogeneous group of disorders of connective tissue, caused mainly by mutations in the collagen I genes (COL1A1 and COL1A2). Dentinogenesis imperfecta (DGI) and other dental aberrations are common features of OI. We investigated the association between collagen I mutations and DGI, taurodontism, and retention of permanent second molars in a retrospective cohort of 152 unrelated children and adolescents with OI. The clinical examination included radiographic evaluations. Teeth from 81 individuals were available for histopathological evaluation. COL1A1/2 mutations were found in 104 individuals by nucleotide sequencing. DGI was diagnosed clinically and radiographically in 29% of the individuals (44/152) and through isolated histological findings in another 19% (29/152). In the individuals with a COL1A1 mutation, 70% (7/10) of those with a glycine substitution located C-terminal of p.Gly305 exhibited DGI in both dentitions while no individual (0/7) with a mutation N-terminal of this point exhibited DGI in either dentition (p = 0.01). In the individuals with a COL1A2 mutation, 80% (8/10) of those with a glycine substitution located C terminal of p.Gly211 exhibited DGI in both dentitions while no individual (0/5) with a mutation N-terminal of this point (p = 0.007) exhibited DGI in either dentition. DGI was restricted to the deciduous dentition in 20 individuals. Seventeen had missense mutations where glycine to serine was the most prevalent substitution (53%). Taurodontism occurred in 18% and retention of permanent second molars in 31% of the adolescents. Dental aberrations are strongly associated with qualitatively changed collagen I. The varying expressivity of DGI is related to the location of the collagen I mutation. Genotype information may be helpful in identifying individuals with OI who have an increased risk of dental aberrations. PMID:28498836

    An experiment was conducted to determine whether the uterotonic effects of oxytocin, a drug used to treat mares that have a delay in uterine clearance were affected by the sedative detomidine (an alpha2-agonist), a drug used to treat fractious mares. An additional objective was to identify propagation patterns of uterine contractions and determine whether these patterns differed between normal mares and mares with delayed uterine clearance (DUC). Intrauterine pressure was measured in five reproductively normal mares and four mares with DUC during estrus using an 8-F Milar catheter with two discrete pressure sensors. Mares received one of three treatments in random order: detomidine (0.001 mg/kg; i.v.); detomidine followed in 10 min by oxytocin (10 IU; i.v.); and saline (0.9% NaCl 0.5 ml; i.v.) followed in 10 min by oxytocin. All treatments induced waves of contractions; however, only three mares with DUC exhibited contractions after administration of detomidine. Normal mares experienced more uterine contractions (P detomidine before oxytocin increased the number of contractions (P Detomidine had no effect in mares with delayed clearance. All mares had more propagating than non-propagating uterine contractions (74 +/- 8 versus 25 +/- 8%, respectively). Normal mares exhibited a normal propagation pattern more frequently (P detomidine increased the number (P detomidine augmented the uterotonic effect of oxytocin in normal mares but not in mares with DUC. Data suggest that mares with DUC have a defect in myoelectrical signaling and a decrease in the contractile strength of the uterine muscle.

    Full Text Available Multiple anomalies including micromelia, poor mineralization of the vertebrae, and a persistent notochord were identified on second trimester ultrasound in a fetus with a COL2A1 mutation. To our knowledge, this represents the first case of a persistent notochord associated with a COL2A1 mutation in humans. In this case report, we describe ultrasound and postmortem findings and review the pathogenesis associated with a persistent notochord.

    Full Text Available Confined to parks and forests, nature in French urban areas has been used as an instrument for urban planners and developers. Recent urban projects have sought to give natural systems a fuller role in territorial development. This new function can be considered a radically new approach. At the same time, current redevelopment projects must also integrate existing facilities. The redevelopment of the banks of the Seine by the Hauts-de-Seine council is a good example of this new role that nature can play in urban revitalisation. Maps show the constraints and issues that must be taken into account.

    On the basis of CT findings, to differentiate between solid ovarian tumor and uterine subserosal myoma. In eight surgically proven cases of solid ovarian tumor and in ten uterine subserosal myoma patients, contrast-enhanced CT images were obtained. Two genitourinary radiologists reviewed the findings with regard to degree of enhancement of the mass as compared with enhancement of uterine myometrium, thickening of round ligaments, visualization of normal ovaries, contour of the mass, and the presence of ascites in the pelvic cavity. Six of eight ovarian tumors but only two of ten uterine myomas were less enhanced than normal uterine myometrium (p<0.05). Pelvic ascites were seen in six of eight ovarian tumors, but in only one of ten uterine myomas (P<0.05). Three of 16 ovaries in ovarian tumor patients, but 12 of 20 ovaries in uterine myoma patients, were normal (p<0.05). Six of 16 round ligaments of the uterus in ovarian tumor patients, were thichened but 11 of 20 round ligaments in uterine myoma patients, were thickened (p>0.05). The contour of the mass was lobulated in two of eight ovarian tumor patients, but in five of ten uterine myoma patients (p>0.05). CT findings suggestive of solid ovarian tumor were less contrast enhancement of the mass than of normal uterine myometrium, pelvic ascites, and nonvisualization of normal ovary.

    Full Text Available BACKGROUND: The collagen11A1 (COL11A1 gene is overexpressed in pancreatic cancer. The expression of COL11A1 protein could be involved in desmoplastic events in pancreatic cancer, but an antibody that specifically stains the COL11A1 protein is not currently available. METHODS AND FINDINGS: A total of 54 pancreatic ductal adenocarcinomas (PDAC, 23 chronic pancreatitis (CP samples, and cultured peritumoral stromal cells of PDAC (passages 3-6 were studied. Normal human pancreas tissue samples were obtained through a cadaveric organ donation program. 1 Validation of COL11A1 gene overexpression by q-RT-PCR. FINDINGS: the expression of COL11A1 gene is significantly increased in PDAC samples vs. normal and CP samples. 2 Analysis of COL11A1 by immunohistochemistry using highly specific anti-proCOL11A1 antibodies. FINDINGS: anti-proCOL11A1 stains stromal cells/cancer-associated fibroblasts (CAFs of PDAC but it does not stain chronic benign condition (chronic pancreatitis stromal cells, epithelial cells, or normal fibroblasts. 3 Evaluation of the discrimination ability of the antibody. FINDINGS: anti-proCOL11A1 immunostaining accurately discriminates between PDAC and CP (AUC 0.936, 95% CI 0.851, 0.981. 4 Phenotypic characterization of proCOL11A1+ stromal cells co-staining with mesenchymal, epithelial and stellate cell markers on pancreatic tissue samples and cultured peritumoral pancreatic cancer stromal cells. FINDINGS: ProCOL11A1+ cells present co-staining with mesenchymal, stellate and epithelial markers (EMT phenotype in different proportions. CONCLUSIONS/SIGNIFICANCE: Detection of proCOL11A1 through immunostaining with this newly-developed antibody allows for a highly accurate distinction between PDAC and CP. Unlike other available antibodies commonly used to detect CAFs, anti-proCOL11A1 is negative in stromal cells of the normal pancreas and almost absent in benign inflammation. These results strongly suggest that proCOL11A1 is a specific marker for

    Full Text Available Osteogenesis imperfecta (OI is a heterogeneous group of disorders of connective tissue, caused mainly by mutations in the collagen I genes (COL1A1 and COL1A2. Dentinogenesis imperfecta (DGI and other dental aberrations are common features of OI. We investigated the association between collagen I mutations and DGI, taurodontism, and retention of permanent second molars in a retrospective cohort of 152 unrelated children and adolescents with OI. The clinical examination included radiographic evaluations. Teeth from 81 individuals were available for histopathological evaluation. COL1A1/2 mutations were found in 104 individuals by nucleotide sequencing. DGI was diagnosed clinically and radiographically in 29% of the individuals (44/152 and through isolated histological findings in another 19% (29/152. In the individuals with a COL1A1 mutation, 70% (7/10 of those with a glycine substitution located C-terminal of p.Gly305 exhibited DGI in both dentitions while no individual (0/7 with a mutation N-terminal of this point exhibited DGI in either dentition (p = 0.01. In the individuals with a COL1A2 mutation, 80% (8/10 of those with a glycine substitution located C terminal of p.Gly211 exhibited DGI in both dentitions while no individual (0/5 with a mutation N-terminal of this point (p = 0.007 exhibited DGI in either dentition. DGI was restricted to the deciduous dentition in 20 individuals. Seventeen had missense mutations where glycine to serine was the most prevalent substitution (53%. Taurodontism occurred in 18% and retention of permanent second molars in 31% of the adolescents. Dental aberrations are strongly associated with qualitatively changed collagen I. The varying expressivity of DGI is related to the location of the collagen I mutation. Genotype information may be helpful in identifying individuals with OI who have an increased risk of dental aberrations.

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

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

    We describe a mild form of disproportionate dwarfism in Labrador Retrievers, which is not associated with any obvious health problems such as secondary arthrosis. We designate this phenotype as skeletal dysplasia 2 (SD2). It is inherited as a monogenic autosomal recessive trait with incomplete penetrance primarily in working lines of the Labrador Retriever breed. Using 23 cases and 37 controls we mapped the causative mutation by genome-wide association and homozygosity mapping to a 4.44 Mb interval on chromosome 12. We re-sequenced the genome of one affected dog at 30x coverage and detected 92 non-synonymous variants in the critical interval. Only two of these variants, located in the lymphotoxin A (LTA) and collagen alpha-2(XI) chain gene (COL11A2), respectively, were perfectly associated with the trait. Previously described COL11A2 variants in humans or mice lead to skeletal dysplasias and/or deafness. The dog variant associated with disproportionate dwarfism, COL11A2:c.143G>C or p.R48P, probably has only a minor effect on collagen XI function, which might explain the comparatively mild phenotype seen in our study. The identification of this candidate causative mutation thus widens the known phenotypic spectrum of COL11A2 mutations. We speculate that non-pathogenic COL11A2 variants might even contribute to the heritable variation in height.

    Full Text Available Charlotte Benson,1 Aisha B Miah1,2 1Sarcoma Unit, Royal Marsden Hospital, 2Department of Radiotherapy and Imaging, The Institute of Cancer Research, London, UK Abstract: Uterine sarcomas comprise a group of rare tumors with differing tumor biology, natural history and response to treatment. Diagnosis is often made following surgery for presumed benign disease. Currently, preoperative imaging does not reliably distinguish between benign leiomyomas and other malignant pathology. Uterine leiomyosarcoma is the most common sarcoma, but other subtypes include endometrial stromal sarcoma (low grade and high grade, undifferentiated uterine sarcoma and adenosarcoma. Clinical trials have shown no definite survival benefit of adjuvant radiotherapy or chemotherapy and have been hampered by the rarity and heterogeneity of these disease types. There is a role of adjuvant treatment in carefully selected cases following multidisciplinary discussion at sarcoma reference centers. In patients with metastatic disease, systemic chemotherapy can then be considered. There is activity of a number of agents, including doxorubicin, trabectedin, gemcitabine-based chemotherapy, eribulin and pazopanib. Patients should be considered for clinical trial entry where possible. Close international collaboration is important to allow progress in this group of diseases.

    This study presents an original work on measurements of stable and radioactive iodinated species in the Seine estuary (France), with estimates fluxes of volatile gaseous species from water to the atmosphere. Various iodinated compounds were identified in water and air in particular 131 I in water, what is unusual. Concentrations and behaviour of iodinated elements in the Seine estuary seem similar to what has been observed in other European estuaries. MeI (Methyl Iodide) and Total Volatile Iodine (TVI) fluxes from water to air vary between 392 and 13949 pmol m -2 d -1 and between 1279 and 16484 pmol m -2 d -1 , respectively. Water to air flux of TVI for the Seine river was estimated in the range 4-46 kg y -1 . Measurements of 131 I in water varying between 0.4 and 11.9 Bq m -3 . Fluxes of 131 I from water to atmosphere are in the range 2.4 x 10 5 -1.3 x 10 7 Bq y -1 , close to an annual discharge of 131 I by a nuclear reactor

    A combined license (COL) application is required by the Nuclear Regulatory Commission (NRC) for all proposed nuclear plants. The information requirements for a COL application are set forth in 10 CFR 52.79, “Contents of Applications; Technical Information in Final Safety Analysis Report.” An applicant for a modular high temperature gas-cooled reactor (HTGR) must develop and submit for NRC review and approval a COL application which conforms to these requirements. The technical information necessary to allow NRC staff to evaluate a COL application and resolve all safety issues related to a proposed nuclear plant is detailed and comprehensive. To this, Regulatory Guide (RG) 1.206, “Combined License Applications for Nuclear Power Plants” (LWR Edition), was developed to assist light water reactor (LWR) applicants in incorporating and effectively formatting required information for COL application review (Ref. 1). However, the guidance prescribed in RG 1.206 presumes a LWR design proposal consistent with the systems and functions associated with large LWR power plants currently operating under NRC license.

    Full Text Available Since a certain time, it is observed, in the spring, in Low Seine, that Salmonidae are coming together. These concentrations concern yearling subjects. Besides, a certain number of adult fisches, marked in Ile de France in 1961-1962-1963, have been captured downstream very far from their introduction point. Because of the investments supported by fishmen for restocking the rivers as well with immediately catchable trouts than with fry and young trouts, it became necessary to try to understand the reasons of the runnings down that has been recorded and to calculate their importance. These investigations have been carried out by a systematic marking of the fishes organized on the whole of the four great hydrographic Regions of the River Seine : — Bassin of the Upper Marne ; — Bassins of the Upper Seine and Upper Aube ; — Bassin of the Upper Aisne. On the 31th October 1967, on 30.030 marked subjects, 3.138 have been caught and recorded. On these 3.138 subjects, 3.049 had not left the Bassin into which they had been introduced. The general mark-returns percentage, reaches 10,15% and the percentage of the distant returns is 3,06‰ The highest returns percentage is this of the Upper Bassin of the River Aisne, where, locally, 34,80% of the marked fishes have been captured. But it can be noted a running down rate in Lower Seine and in the sea of 2,94‰ for the Upper Marne; 2,20‰ for the River Aube and the Upper Seine and 4,71‰ for the Ile de France. The highest removing is this of a trout introduced in Ardennes Country and which has been caught at Dunkerque Harbourgh after a travel of 805 kilometers, 530 of wihch made in fresh water. Investigations by marking have been completed by biometrical studies carried out on samples drawn of Lower Seine, at the time of the big concentrations of the winter end. A certain number of constatations derives from it : — There are groups of fishes which are inclined to run down-stream, more than the others

    The aim of our study was to compare the stage and severity of endometriosis in fertile and infertile women with congenital uterine malformations. We performed an observational study from September 2007 to December 2015 in a tertiary care university hospital and assisted reproductive technology center. A total of 52 patients with surgically proven uterine malformations were included. We compared 41 infertile patients with uterine malformations with 11 fertile patients with uterine malformation. The main outcome was the stage, score and type of endometriosis in regard to infertility and class of uterine malformation. The rate of endometriosis did not differ between the two groups (43.9 vs. 36.4%). The mean revised American Fertility Society score was higher in infertile patients with uterine malformations (19.02 vs. 6, p endometriosis (43.9 vs. 37.5%). Endometrioma and deep infiltrating endometriosis were associated with uterine malformations in infertile women, respectively 14.6 and 0%. No difference in the characteristics of endometriosis was found regarding the class of malformation. The association of uterine malformations and infertility may increase the severity of endometriosis and raise the issue of their diagnosis and management. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

  11. Estimating juvenile Chinook salmon (Oncorhynchus tshawytscha) abundance from beach seine data collected in the Sacramento–San Joaquin Delta and San Francisco Bay, California

    Resource managers rely on abundance or density metrics derived from beach seine surveys to make vital decisions that affect fish population dynamics and assemblage structure. However, abundance and density metrics may be biased by imperfect capture and lack of geographic closure during sampling. Currently, there is considerable uncertainty about the capture efficiency of juvenile Chinook salmon (Oncorhynchus tshawytscha) by beach seines. Heterogeneity in capture can occur through unrealistic assumptions of closure and from variation in the probability of capture caused by environmental conditions. We evaluated the assumptions of closure and the influence of environmental conditions on capture efficiency and abundance estimates of Chinook salmon from beach seining within the Sacramento–San Joaquin Delta and the San Francisco Bay. Beach seine capture efficiency was measured using a stratified random sampling design combined with open and closed replicate depletion sampling. A total of 56 samples were collected during the spring of 2014. To assess variability in capture probability and the absolute abundance of juvenile Chinook salmon, beach seine capture efficiency data were fitted to the paired depletion design using modified N-mixture models. These models allowed us to explicitly test the closure assumption and estimate environmental effects on the probability of capture. We determined that our updated method allowing for lack of closure between depletion samples drastically outperformed traditional data analysis that assumes closure among replicate samples. The best-fit model (lowest-valued Akaike Information Criterion model) included the probability of fish being available for capture (relaxed closure assumption), capture probability modeled as a function of water velocity and percent coverage of fine sediment, and abundance modeled as a function of sample area, temperature, and water velocity. Given that beach seining is a ubiquitous sampling technique for

    L'objectif était de déterminer la prévalence de l'infection à VIH chez les patientes atteintes de cancer du sein et de comparer les caractéristiques anatomocliques et thérapeutiques de ces cancers du sein par rapports aux patientes non infectées par le VIH. Il s'agissait d'une étude rétrospective et analytique comparant les dossiers de patientes atteintes de cancers du sein histologiquement confirmés, infectées ou non par le VIH à l'unité de chirurgie oncologique de Donka, CHU de Conakry, de 2007 à 2012. Nous avons colligé 278 patientes présentant un cancer du sein dont 14 (5,0%) infectées par le VIH et 264 (95,0%) non infectées par le VIH. Les différences observées entre ces deux groupes de patientes étaient respectivement: âge médian (36,8 vs 49,0 ans), la ménopause (21,4% vs 53,4%), le nombre des patientes traitées (50,0% contre 77,1%) et la survenue de décès (78,6% vs 50,8%). Aucune différence n'a été notée dans la présentation clinique, histologique et le retard de consultation. Dans notre étude, la prévalence de l'infection à VIH chez les patients atteints de cancer du sein est élevée. L’âge jeune des patients, la faible accessibilité au traitement et la mortalité élevée doivent être confirmés par une étude sur un échantillon plus large. PMID:26523196

    2018-05-01

    Full Text Available Incidence of post- partum uterine disease is an important concern in dairy cattle, because it affects its reproduction. Therefore, the objective of this review of literature was to generate a multifactorial overview about uterine diseases, and the reproductive performance of dairy cows, from a zootechnical approach. Dairy cows face multiple challenges around parturition. Immune suppression around calving, exposition to trauma and uterine bacterial contamination, metabolic diseases, lactation, and changes in management make dairy cows susceptible to uterine diseases. Most cows are able to eliminate uterine infection after calving, however, some cows keep uterine disease. Uterine disease may show clinical signs, but also silent signs that affect fertility as well. Poor reproductive performance is not caused by those signs by themselves, but due to alterations in ovarian and uterine function. Also, the problem of this silent signs is that farmers become aware of the disease when it has already caused negative effects on the reproductiveperformance. Sometimes, uterine disease is still present at the moment of the first service after calving. Uterine diseasemake it harder for cows to get pregnant because it affects the establishment and maintenance of pregnancy, being another cause for infertility, increasing the cull rate and decreasing incomes from the dairy industry.

    Full Text Available OBJECTIVES To evaluate whether saline contrast sonohysterography (SCSH improved the diagnostic accuracy of transvaginal sonography (TVS for predicting endometrial abnormality in premenopausal patients with abnormal uterine bleeding. PATIENTS AND METHODS The uterine cavity was evaluated with TVS and SCSH in 60 premenopausal patients with abnormal uterine bleeding. All 58 patients underwent operative hysteroscopy or hysterectomy within 4 months which provided a detailed description of the uterine cavity and was used as the true value for exclusion of polyps and submucous myomas. RESULT Out of 60 patients, 45 had uterine abnormalities on TVS and SCSH and rest of the patients who appeared normal but had other abnormalities such as ovarian haemorrhagic cyst. Out of the 45 patients, 9 patients had submucous myomas and 9 were diagnosed as endometrial polyp. The findings were confirmed using hysterectomy/hysteroscopy/endometrial sampling. CONCLUSION The use of TVS without saline contrast left nine submucosal fibroids and five in nine of the polyps undiagnosed in referred patients with complaints of abnormal bleeding. It also helps in reducing the rate of more invasive procedures such as hysteroscopy. However, studies carried out for longer duration and large study population are required to validate our findings

    Uterine lipoleiomyoma is a rare and specific type of leiomyoma. A 60-year-old postmenopausal woman presented with abdominal pain. Her pelvic ultrasound demonstrated a normal- sized uterus with a well- circumscribed, heterogeneous mass located in the anterior corpus. A pelvic MRI revealed a mass including hyperintense areas on T1-weighted images and hypointense on fat-suppressed T1-weighted images, compatible with lipoleiomyoma. Uterine lipoleiomyomas are often misdiagnosed pre-operatively and it is important to distinguish leiomyomas from other tumors for prevention from supererogatory surgery. Imaging plays an important role for the exact differentiation

    The etiology and pathophysiology of uterine leiomyomas, benign smooth muscle tumors of the uterus, are not well understood. To evaluate the role of mitochondria in uterine leiomyoma, we compared electron transport gene expressions of uterine leiomyoma tissue with myometrium tissue in six uterine leiomyoma patients by RT-PCR array. Our results showed an average of 1.562 (±0.445) fold increase in nuclear-encoded electron transport genes. These results might suggest an increase in size, number, or activity of mitochondria in uterine leiomyoma that, to our knowledge, has not been previously reported. © 2014 by the Association of Clinical Scientists, Inc.

  18. Uterine biology in pigs and sheep

    Full Text Available Abstract There is a dialogue between the developing conceptus (embryo-fetus and associated placental membranes and maternal uterus which must be established during the peri-implantation period for pregnancy recognition signaling, implantation, regulation of gene expression by uterine epithelial and stromal cells, placentation and exchange of nutrients and gases. The uterus provide a microenvironment in which molecules secreted by uterine epithelia or transported into the uterine lumen represent histotroph required for growth and development of the conceptus and receptivity of the uterus to implantation. Pregnancy recognition signaling mechanisms sustain the functional lifespan of the corpora lutea (CL which produce progesterone, the hormone of pregnancy essential for uterine functions that support implantation and placentation required for a successful outcome of pregnancy. It is within the peri-implantation period that most embryonic deaths occur due to deficiencies attributed to uterine functions or failure of the conceptus to develop appropriately, signal pregnancy recognition and/or undergo implantation and placentation. With proper placentation, the fetal fluids and fetal membranes each have unique functions to ensure hematotrophic and histotrophic nutrition in support of growth and development of the fetus. The endocrine status of the pregnant female and her nutritional status are critical for successful establishment and maintenance of pregnancy. This review addresses the complexity of key mechanisms that are characteristic of successful reproduction in sheep and pigs and gaps in knowledge that must be the subject of research in order to enhance fertility and reproductive health of livestock species.

    2003-01-01

    To evaluate the current situation and implementation of embolization of uterine leiomyomas into the treatment concept in women with symptomatic uterine leiomyomas in Germany. A questionnaire addressing the clinical background of uterine myomas, recommended treatment concepts, preclinical evaluation, technical approach and complications was sent to 164 departments of gynecology and radiology in Germany. 33 radiological departments and 19 gynecological departments submitted a completed questionnaire. Only 7 departments of radiology reported to have own experience with embolization of uterine leiomyomas, while only 2 departments of gynecology considered embolization as an alternative treatment option in patients with symptomatic leiomyomas. 18/33 radiological departments offer this treatment option but get no patient referrals. Agreement was found concerning the indications for treatment, preclinical evaluation by ultrasound and MRI, preferable location of treatable fibroids, technical approach and pain management. The embolization of uterine leiomyomas in patients with symptomatic myomas is regardless of the well documented high efficacy and low complication rate not yet an established treatment option in Germany. Interventional radiologists and gynecologists have to evaluate the indications for the embolization of uterine leiomyomas together before the procedure is advised to the patient, because it seems mandatory to add this procedure to the standard armamentarium of treatment options in uterine myomas.

  20. A COL11A2 mutation in Labrador retrievers with mild disproportionate dwarfism.

    Full Text Available We describe a mild form of disproportionate dwarfism in Labrador Retrievers, which is not associated with any obvious health problems such as secondary arthrosis. We designate this phenotype as skeletal dysplasia 2 (SD2. It is inherited as a monogenic autosomal recessive trait with incomplete penetrance primarily in working lines of the Labrador Retriever breed. Using 23 cases and 37 controls we mapped the causative mutation by genome-wide association and homozygosity mapping to a 4.44 Mb interval on chromosome 12. We re-sequenced the genome of one affected dog at 30x coverage and detected 92 non-synonymous variants in the critical interval. Only two of these variants, located in the lymphotoxin A (LTA and collagen alpha-2(XI chain gene (COL11A2, respectively, were perfectly associated with the trait. Previously described COL11A2 variants in humans or mice lead to skeletal dysplasias and/or deafness. The dog variant associated with disproportionate dwarfism, COL11A2:c.143G>C or p.R48P, probably has only a minor effect on collagen XI function, which might explain the comparatively mild phenotype seen in our study. The identification of this candidate causative mutation thus widens the known phenotypic spectrum of COL11A2 mutations. We speculate that non-pathogenic COL11A2 variants might even contribute to the heritable variation in height.

    Objective: To assess the clinical value of uterine arterial embolization (UAE) in treating uterine scar pregnancy after cesarean section. Methods: A total of' 35 cases with cesarean scar pregnancy, admitted to authors' hospital during the period from Jan. 2007 to June 2011, were divided into two groups: embolization group (n=21) and non-embolization group (n=14). By using Seldinger technique, UAE was performed via the right femoral access and gelatin sponge particle was used as embolization agent to occlude the uterine artery. In embolization group, sixteen patients received uterine cavity curettage one or two days after UAE, while five patients received laparotomy or perineotomy surgery to remove the lesions after UAE. In non-embolization group, uterine cavity curettage was performed directly in 8 patients, local injection of' methotrexate followed by uterine cavity curettage was carried out in 3 patients, and direct laparotomy to remove the lesions was adopted in the remaining 3 patients. The blood loss during the procedure, the hospitalization days and the time for β-HCG levels falling to normal were documented. The results were compared between the two groups. Results: UAE was successfully accomplished in all the 21 patients of embolization group and the uterus was preserved in all patients. For the embolization group, the mean hospitalization time was (11.5±3.6) days, and the time for β-HCG levels falling to normal was (18.6±4.9) days. For the non-embolization group, the mean hospitalization time was(20.4±5.2)days, and the time for β-HCG levels falling to normal was (28.7±5.6)days. Hysterectomy had to be carried out in two patients of non-embolization group due to the massive bleeding occurred in therapeutic procedures. Conclusion: For the treatment of cesarean scar pregnancy, UAE is very effective and mini-invasive with high success rate. UAE can preserve the patient's reproductive function, and it also plays a significant role in preventing hemorrhage

    Serial images of uterine leiomyoma in gradient-echo, echo-planar, magnetic resonance imaging were taken to draw a {delta}R2{sup *} curve after intravenous bolus injection of Gd-DTPA. The {delta}R2{sup *} integral was calculated from a {delta}R2{sup *} curve to have relative perfusion of uterine leiomyoma. We then, evaluated the amount of perfusion correlated with MR findings, size and number of leiomyoma or the clinical symptoms and established that perfusion was correlated positively with the findings of T2 weighted images and clinical symptoms but not with other MR findings or size and number of leiomyoma. In conclusion, we presumed that the clinical symptoms could be reduced by decreasing of an amount of perfusion of uterine leiomyoma in some means. However, it remained uncertain why severe clinical symptoms were associated with a high amount of perfusion in uterine leiomyomas. (author)

    A Pseudomonas fluorescens isolate (PF-1) resistant to carbapenems was recovered during an environmental survey performed with water from the Seine River (Paris). It expressed a novel Ambler class A carbapenemase, BIC-1, sharing 68 and 59% amino acid identities with beta-lactamases SFC-1 from Serratia fonticola and the plasmid-encoded KPC-2, respectively. beta-Lactamase BIC-1 hydrolyzed penicillins, carbapenems, and cephalosporins except ceftazidime and monobactams. The bla(BIC-1) gene was chromosomally located and was also identified in two other P. fluorescens strains isolated from the Seine River 3 months later.

    Purpose:To evaluate in a prospective study the use of a 4F Rosch inferior mesenteric (RIM) catheter for uterine artery embolisation (UAE). UAE was performed in 72 women over a 37-month period. A 4F RIM braided J-curve 65-cm catheter was used in combination with an angled hydrophilic 150 cm, 0.035'' flexible tip guide-wire to catheterise the horizontal portion of both uterine arteries (UA) from a right common femoral artery (CFA) approach. Technical success was defined as successful catheterisation and embolisation of both uterine arteries. Fluoroscopic and procedure times were recorded. Mean subject age=43.7 years (range=25-57 years). Technical success was 98.6% (n=71/72). A single approach via the right CFA was used in 88.9% (n=64/72) and a bilateral CFA approach in 11.1% (n=8/72). Bilateral uterine artery catheterisation using a single 4F RIM catheter via the right CFA approach was successful in 79.2% (n=57/72). Microcatheters were used in 2.8% of patients (n=2/72). Mean fluoroscopic time=13.6±5.3 min (mean±SD). Mean procedure time=44.2±16.5 min. High technical success rate for UAE is possible using a single 4F RIM catheter via a unilateral right CFA approach, which obviates the need for Waltman loop formation, reversed curve catheters and complex suture-catheter arrangements.

    Full text: Introduction: Today, after numerous lengthy randomized trials embolization of uterine fibroids has become a standard treatment. Percutaneous embolization of myomas is a micro - invasive surgery, which can be regarded as an alternative to traditional surgery. Although these data 2/3 of the patients were not informed about this treatment option. What you will learn: The uterine embolization is minimal invasive non-surgical procedure. It is an alternative treatment to surgery. Under local anesthesia in the femoral artery puncture reaches the internal iliac artery and uterine arteries. Reached selectively by the catheter and chemicals, which causes clogging, are injected into them. In the vessels that feed fibroids occur a process like an attack, the feeding stops, it starts to shrink and it is replaced by fibrous tissue. The blood vessels of the healthy tissue are different in size and have a plurality of collateral connections as opposed to those of the myoma and thus the blood supply to the normal tissue of the uterus is not distorted. Discussion: Nowadays there are more well- calibrated materials for embolization and those with a particle size of about 700µ are proven as the most successful. The procedure is well tolerated, but after a pain occurs, which has to be covered with anesthetics. Usually pain and metrorrhagia disappear immediately. The fibroids themselves shrink to varying degrees. Hospital stay was significantly shorter than that after surgery, and remained fertile power. Complications are few and rare require further treatment. Multiple nodes are problematic and it is difficult to detect the primary one. A three and six months tracking by MRI is desirable. Conclusion: Embolization of uterine myoma is an established method of treatment primarily on clinical symptoms resulting therefrom. In all patients rapidly disappear metrorrhagia symptoms and morbidity, the volume of the assembly decrease, which together with shorter hospital stays and

    Résumé Objectif Résumer les meilleures données portant sur les stratégies d’identification et de prise en charge des femmes qui présentent des antécédents familiaux de cancer du sein. Sources d’information Une recherche a été effectuée sur PubMed à l’aide des mots-clés anglais suivants : breast cancer, guidelines, risk, family history, management et magnetic resonance imaging screening, entre 2000 et 2016. La plupart des données sont de niveau II. Message principal Une bonne anamnèse familiale est essentielle lors de l’évaluation du risque de cancer du sein afin d’identifier les femmes qui sont candidates à une recommandation en counseling génétique pour un éventuel test génétique. On peut sauver des vies en offrant aux femmes porteuses d’une mutation au gène BRCA des interventions chirurgicales de réduction des risques (mastectomie bilatérale prophylactique, salpingo-ovariectomie bilatérale). Il faut encourager toutes les femmes qui présentent des antécédents familiaux de cancer du sein à demeurer actives et à limiter leur consommation d’alcool à moins de 1 verre par jour; certaines femmes sont admissibles à la chimioprévention. Il faut offrir aux femmes dont le risque à vie de cancer du sein est de 20 à 25 % ou plus un dépistage poussé par imagerie par résonance magnétique en plus d’une mammographie. Conclusion Une vie saine et la chimioprévention (chez les candidates) pourraient réduire l’incidence du cancer du sein; le dépistage poussé pourrait entraîner une détection plus précoce. Le fait d’aiguiller des femmes porteuses d’une mutation au BRCA vers la chirurgie de réduction des risques sauve des vies. PMID:27737991

  9. Modelling the spatial behaviour of a tropical tuna purse seine fleet.

    Full Text Available Industrial tuna fisheries operate in the Indian, Atlantic and Pacific Oceans, but concerns over sustainability and environmental impacts of these fisheries have resulted in increased scrutiny of how they are managed. An important but often overlooked factor in the success or failure of tuna fisheries management is the behaviour of fishers and fishing fleets. Uncertainty in how a fishing fleet will respond to management or other influences can be reduced by anticipating fleet behaviour, although to date there has been little research directed at understanding and anticipating the human dimension of tuna fisheries. The aim of this study was to address gaps in knowledge of the behaviour of tuna fleets, using the Indian Ocean tropical tuna purse seine fishery as a case study. We use statistical modelling to examine the factors that influence the spatial behaviour of the purse seine fleet at broad spatiotemporal scales. This analysis reveals very high consistency between years in the use of seasonal fishing grounds by the fleet, as well as a forcing influence of biophysical ocean conditions on the distribution of fishing effort. These findings suggest strong inertia in the spatial behaviour of the fleet, which has important implications for predicting the response of the fleet to natural events or management measures (e.g., spatial closures.

    Uterine leiomyomas are the most common benign uterine neoplasms. Undegenerated uterine leiomyomas are easily recognizable by the typical imaging findings on radiologic studies. However, degenerated fibroids can have unusual and variable appearances. The atypical appearances due to degenerative changes may cause confusion in diagnosis of leiomyomas. In this article, we report a case of a patient with extensive cystic and myxoid degeneration of uterine leiomyoma, mimicking malignant bilateral ovarian surface epithelial tumors.

    By means of re-irradiation using pepleomycin suppository in uterine cavity, we attained local control for one patient who had local recurrence in uterine cavity and suffered from uterine fluor in which viable cancer cells were confirmed. We were enlightened by this therapeutic experience, so we attempted combination therapy using pepleomycin suppositories to supplement intra-cavitary irradiation, for the 11 selected patients who were suffering from uterine fluor. We investigated the treatment results in 7 patients of stage III out of 11 patients (of all stages), in comparison with 13 patients of stage III who were treated by irradiation alone. Consequently, these treatment results were approximately equivalent, and the incidence of sigmoid complications could be decreased. Side effects which were followed by the combination therapy were not serious, and so we believe that pepleomycin suppository is a simple method and valuable to supplement radiation therapy of uterine cervical cancer.

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

    To test whether variations in apparent diffusion coefficient (ADC) values of uterine leiomyomas after uterine artery embolization (UAE) may correlate with outcome and assess the effects of UAE on leiomyomas and normal myometrium with magnetic resonance imaging (MRI). Data of 49 women who underwent pelvic MRI before and after UAE were retrospectively reviewed. Uterine and leiomyoma volumes, ADC values of leiomyomas, and normal myometrium were calculated before and after UAE. By comparison with baseline ADC values, a significant drop in leiomyoma ADC was found at 6-month post-UAE (1.096 x 10"-"3 mm"2/s vs. 0.712 x 10"-"3 mm"2/s, respectively; p < 0.0001), but not at 48-h post-UAE. Leiomyoma devascularization was complete in 40/49 women (82 %) at 48 h and in 37/49 women (76 %) at 6 months. Volume reduction and leiomyoma ADC values at 6 months correlated with the degree of devascularization. There was a significant drop in myometrium ADC after UAE. Perfusion defect of the myometrium was observed at 48 h in 14/49 women (28.5 %) in association with higher degrees of leiomyoma devascularization. Six months after UAE, drop in leiomyoma ADC values and volume reduction correlate with the degree of leiomyoma devascularization. UAE affects the myometrium as evidenced by a drop in ADC values and initial myometrial perfusion defect. (orig.)

    Our studies showed that an apple B-box protein, MdCOL11, the homolog of AtBBX22, is involved in UV-B- and temperature-induced anthocyanin biosynthesis in apple peel. Anthocyanin is responsible for the red pigmentation in apple peel and a R2R3 MYB gene, MdMYBA/1/10, a homolog of MdMYBA, controls its accumulation. Arabidopsis PAP1 is under the control of a series of upstream factors involved in light signal transduction and photomorphogenesis, such as ELONGATED HYPOCOTYL 5 (HY5) and B-box family (BBX) proteins. In this study, we identified and characterized the homolog of Arabidopsis BBX22 in apple, designated as MdCOL11. Overexpression of MdCOL11 in Arabidopsis enhanced the accumulation of anthocyanin. In apples, MdCOL11 was differentially expressed in all tissues, with the highest expression in petals and the lowest expression in the xylem. Transcripts of MdCOL11 noticeably accumulated at the ripening stage, concomitant with increases in the expressions of anthocyanin biosynthesis-related genes. In an in vitro treatment experiment, MdCOL11 was upregulated in an ultra-violet (UV)-B- and temperature-dependent manner, together with the inductions of anthocyanin biosynthesis-related genes and anthocyanin accumulation in apple peel. Furthermore, a dual-luciferase assay indicated that (1) MdCOL11 regulated the expression of MdMYBA and (2) MdCOL11 was a target of MdHY5. Taken together, our results suggest that MdCOL11 is involved in MdHY5-mediated signal transduction and regulates anthocyanin accumulation in apple peel, which sheds new light on anthocyanin accumulation in apples.

    Uterine electrical activity is correlated to the appearance of uterine contractions. forceful contractions appear at the end of term. Therefore, understanding the genesis and the propagation of uterine electrical activity may provide an efficient tool to diagnose preterm labor. Moreover, the control of uterine excitability seems to have important consequences in the control of preterm labor. Modeling the electrical activity in uterine tissue is thus an important step in understanding physiological uterine contractile mechanisms and to permit uterine EMG simulation. Our model presented in this paper, incorporates ion channel models at the cell level, the reaction diffusion equations at the tissue level and the spatiotemporal integration at the uterine EMG reconstructed level. This model validates some key physiological observation hypotheses concerning uterine excitability and propagation.

    Uterine sarcomas comprise a group of rare tumors with differing tumor biology, natural history and response to treatment. Diagnosis is often made following surgery for presumed benign disease. Currently, preoperative imaging does not reliably distinguish between benign leiomyomas and other malignant pathology. Uterine leiomyosarcoma is the most common sarcoma, but other subtypes include endometrial stromal sarcoma (low grade and high grade), undifferentiated uterine sarcoma and adenosarcoma. Clinical trials have shown no definite survival benefit of adjuvant radiotherapy or chemotherapy and have been hampered by the rarity and heterogeneity of these disease types. There is a role of adjuvant treatment in carefully selected cases following multidisciplinary discussion at sarcoma reference centers. In patients with metastatic disease, systemic chemotherapy can then be considered. There is activity of a number of agents, including doxorubicin, trabectedin, gemcitabine-based chemotherapy, eribulin and pazopanib. Patients should be considered for clinical trial entry where possible. Close international collaboration is important to allow progress in this group of diseases. PMID:28919822

    Uterine fibroids, also known as uterine leiomyomas, are a benign tumor of the human uterus and the commonest estrogen-dependent benign tumor found in women. Myocardin is an important transcriptional regulator in smooth and cardiac muscle development. The role of myocardin and its relationship with ERα in uterine fibroids have barely been addressed. We noticed that the expression of myocardin was markedly reduced in human uterine fibroid tissue compared with corresponding normal or adjacent myometrium tissue. Here we reported that myocardin induced the transcription and expression of differentiation markers SM22α and alpha smooth muscle actin (α-SMA) in rat primary uterine smooth muscle cells (USMCs) and this effect was inhibited by ERα. Notably, we showed that, ERα induced expression of proliferation markers PCNA and ki-67 in rat primary USMCs. We also found ERα interacted with myocardin and formed complex to bind to CArG box and inhibit the SM22α promoter activity. Furthermore, ERα inhibited the transcription and expression of myocardin, and reduced the levels of transcription and expression of downstream target SM22α, a SMC differentiation marker. Our data thus provided important and novel insights into how ERα and myocardin interact to control the cell differentiation and proliferation of USMCs. Thus, it may provide potential therapeutic target for uterine fibroids.

    Objective: Aim of the study was to control life threatening post partum haemorrhage (PPH) in women till blood and blood products were made available or the women transferred to a better equipped centre. Study Design: A prospective interventional consecutive case series. Place and Duration of Study: It was conducted in three hospitals; Heavy Industries Taxila (HIT) hospital Apr 2005 to Sep 2010, Pakistan Ordinance Factories (POF) hospital Wah cantt Oct 2011 to Dec 2014 and Combined Military Hospital (CMH) Tarbela Dec 2014 to Dec 2015. Material and Methods: Abdominal binder was used in 22 consecutive women, having moderate to severe primary PPH due to uterine atony, where despite uterotonics (i.v oxytocin, rectal misoprostol) and bimanual compression, uterine tamponade was performed but complete control of haemorrhage was not achieved. Protocols for the treatment of obstetric haemorrhage and hypotensive shock were observed, including administration of intravenous crystalloid fluids and blood transfusion. If required, surgery was performed in the form of uterine arteries ligation or B-Lynch sutures. Obstetric hysterectomy was performed to save the woman's life if conservative procedures failed. Results: Bleeding and hypotension were controlled successfully in 19 (86.4%) of these women. In 03 (14.6%) women, bleeding persisted and so hysterectomy had to be resorted to. There was no maternal mortality. At 06 weeks postnatal follow up, none of the patients were found to suffer from long term debility; physical or psychological. Conclusion: Abdominal binder was found to be very effective in controlling bleeding and hypotensive crisis due to significant PPH due to uterine atony, as an adjunct to uterine tamponade. (author)

  3. Case of Small Vessel Disease Associated with COL4A1 Mutations following Trauma

    Full Text Available With this case report, we would like to heighten the awareness of clinicians about COL4A1 as a single-gene disorder causing cerebral small vessel disease and describe a previously unreported pathogenic missense substitution in COL4A1 (p.Gly990Val and a new clinical presentation. We identified a heterozygous putatively pathogenic mutation of COL4A1 in a 50-year-old female with a history of congenital cataracts and glaucoma who presented with multiple diffusion-positive infarcts and areas of contrast enhancement following mild head trauma. We believe that this presentation of multiple areas of acute brain and vascular injury in the setting of mild head trauma is a new manifestation of this genetic disorder. Imaging findings of multiple acute infarcts and regions of contrast enhancement with associated asymptomatic old deep microhemorrhages and leukomalacia in adults after head trauma should raise a high suspicion for a COL4A1 genetic disorder. Radiographic patterns of significant leukoaraiosis and deep microhemorrhages can also be seen in patients with long-standing vasculopathy associated with hypertension, which our patient lacked. Our findings demonstrate the utility of genetic screening for COL4A1 mutations in young patients who have small vessel vasculopathy on brain imaging but who do not have significant cardiovascular risk factors.

    In the recent years, angiogenetic inhibitors have emerged for the treatment of several malignancies. In particular, bevacizumab has proved to be effective in many types of cancers (including sarcoma), but the limitations of antiangiogenic therapy have been shown in practice. Here, we sought to review the current evidence on the role and efficacy of bevacizumab in patients affected by uterine leiomyosarcoma. On April 2017, Literature was searched in order to identify studies reporting outcomes of patients affected either by early stage or advanced/recurred uterine leiomyosarcoma undergoing treatment with bevacizumab, alone or in combination with other chemotherapeutic regimens. Searching the literature data of 69 patients affected by metastatic, unresectable uterine leiomyosarcoma were retrieved; on the contrary, no data regarding the use of bevacizumab in patients with early-stage uterine leiomyosarcoma was published. Current evidence suggested that the addiction of bevacizumab to standard treatment modality does not increase grade 3 or worse toxicity (assessed by CTCAE). Pooled data regarding response rate suggested that 35%, 28%, 26% and 11% of patients experienced objective cure (complete + partial response), stable disease, progressive disease and unknown response, respectively. Data from the only one randomized controlled trial suggested that objective cure rate does not differ from standard chemotherapy treatment, thus limiting the indication to add bevacizumab in patients affected by metastatic, unresectable uterine leiomyosarcoma. The current evidence does not justify the use of bevacizumab into clinical practice. Further randomized studies testing the role of bevacizumab are warranted. Copyright © 2018 Elsevier B.V.

    Full Text Available Marine mammal interactions with Portuguese purse-seine fisheries operating in four different ports (Figueira da Foz, Sesimbra, Setúbal, Sines were studied (July-October 2003. Observers accompanied commercial fishing vessels and monitored 48 fishing trips. An interview survey of skippers was also carried out (n = 36. Three species of marine mammals were observed in 31 sightings during the commercials trips but only the species Delphinus delphis and the category Delphinidae were observed to interact with fishing activities. Small cetaceans were observed to sink, gather or disperse school fishes and damage gear. Mean CPUE and fishing effort values did not change significantly in the presence of dolphins (H = 0.06 and H = 0, both p>0.05. Results from Figueira da Foz indicate that cetaceans are attracted to fishing grounds with a high abundance of their prey-species. Fishermen reported three by-catch events off Figueira da Foz. Compared with other fisheries, purse-seine fishing does not seem to be among the most damaging to marine mammals.

    The uterus is a physiological system consisting of a large number of interacting smooth muscle cells. The uterine excitability changes remarkably with time, generally quiescent during pregnancy, the uterus exhibits forceful synchronized contractions at term leading to fetus expulsion. These changes characterize thus a dynamical system susceptible of being studied through formal mathematical tools. Multiple physiological factors are involved in the regulation process of this complex system. Our aim is to relate the physiological factors to the uterine cell dynamic behaviors. Taking into account a previous work presented, in which the electrical activity of a uterine cell is described by a set of ordinary differential equations, we analyze the impact of physiological parameters on the response of the model, and identify the main subsystems generating the complex uterine electrical activity, with respect to physiological data.

    2017-08-01

    Full Text Available Background: Although leiomyomas are the most common gynecologic disorders, non-puerperal uterine inversion due to leiomyoma is considered as a rare clinical problem. This condition can occur as a complication of a large sub-mucous leiomyoma that leads to dilate cervix and protrude into vagina. The patient may have several symptoms such as heavy vaginal bleeding, pelvic pain and intermittent acute urinary retention. Case: We presented a 32-year-old nulliparous woman with 17 years of unexplained infertility and diagnosis of a large vaginal prolapsed non-pedunculated leiomyoma. Conclusion: Haultain’s procedure was used to reposition uterine inversion and remove leiomyoma through a posterior incision, using laparotomy

    Résumé Objectif Offrir aux médecins de famille un résumé des recommandations fondées sur les données probantes pour guider les soins aux survivantes traitées pour le cancer du sein. Qualité des données Une recherche documentaire a été effectuée dans MEDLINE entre 2000 et 2016 à l’aide des mots-clés anglais suivants : breast cancer, survivorship, follow-up care, aftercare, guidelines et survivorship care plans, en se concentrant sur la revue des lignes directrices publiées récemment par les organismes nationaux de cancérologie. Les données étaient de niveaux I à III. Message principal Les soins aux survivantes comportent 4 facettes : surveillance et dépistage, prise en charge des effets à long terme, promotion de la santé et coordination des soins. La surveillance des récidives ne se traduit que par une mammographie annuelle, et le dépistage d’autres cancers doit suivre les lignes directrices basées sur la population. La prise en charge des effets à long terme du cancer et de son traitement aborde des problèmes courants tels la douleur, la fatigue, le lymphœdème, la détresse et les effets indésirables des médicaments, de même que les préoccupations à long terme comme la santé du cœur et des os. La promotion de la santé met en relief les bienfaits de l’activité chez les survivantes du cancer, avec l’accent mis sur l’activité physique. Les soins aux survivantes sont de meilleure qualité lorsque divers services et professionnels de la santé participent aux soins, et le médecin de famille joue un rôle important dans la coordination des soins. Conclusion Les médecins de famille sont de plus en plus souvent les principaux fournisseurs de soins de suivi après le traitement du cancer du sein. Le cancer du sein doit être considéré comme une affection médicale chronique, même chez les femmes en rémission, et les patientes profitent de la même approche que celle utilisée pour les autres affections chroniques en

    Seine river region is an extremely important logistic and economic junction for France and Europe. The hydraulic protection of most part of the region relies on four controlled reservoirs, managed by EPTB Seine-Grands Lacs. Presently, reservoirs operation is not centrally coordinated, and release rules are based on empirical filling curves. In this study, we analyze how a centralized release policy can face flood and drought risks, optimizing water system efficiency. The optimal and centralized decisional problem is solved by Stochastic Dual Dynamic Programming (SDDP) method, minimizing an operational indicator for each planning objective. SDDP allows us to include into the system: 1) the hydrological discharge, specifically a stochastic semi-distributed auto-regressive model, 2) the hydraulic transfer model, represented by a linear lag and route model, and 3) reservoirs and diversions. The novelty of this study lies on the combination of reservoir and hydraulic models in SDDP for flood and drought protection problems. The study case covers the Seine basin until the confluence with Aube River: this system includes two reservoirs, the city of Troyes, and the Nuclear power plant of Nogent-Sur-Seine. The conflict between the interests of flood protection, drought protection, water use and ecology leads to analyze the environmental system in a Multi-Objective perspective.

    In this article, we present the views on uterine cancer of the ancient Greek physicians. We emphasize on uterine's cancer aetiology according to the dominant in antiquity humoural theory, on its surgical treatment suggested by Soranus of Ephesus, and in the vivid description provided by Aretaeus of Cappadocia. During that period, uterine cancer was considered as an incurable and painful malignancy and its approach was mainly palliative.

    Full Text Available Wan-Cheng Zhao,1 Fang-Fang Bi,1 Da Li,2 Qing Yang11Department of Obstetrics and Gynecology, 2Center of Reproductive Medicine, Shengjing Hospital of China Medical University, Shenyang, People’s Republic of ChinaBackground: Uterine fibroids often require a hysterectomy or myomectomy via laparotomy or laparoscopy. Morcellation is often necessary to perform a laparoscopic surgery. The objective of this study is to determine the incidence of unexpected uterine sarcomas (UUSs after hysterectomy and myomectomy for uterine fibroids and to reduce the occurrence and avoid the morcellation of UUSs by analyzing their characteristics.Methods: Women who had a hysterectomy or myomectomy for uterine fibroids in Shengjing Hospital of China Medical University between November 2008 and November 2014 were selected for the study, and their clinical characteristics were analyzed.Results: During the period, 48 UUSs were found in 10,248 cases, and the overall incidence was 0.47%. There was no statistical difference (P=0.449 regarding the incidence (0.50% vs 0.33% between 42 UUSs in 8,456 cases undergoing laparotomy and six UUSs in 1,792 cases undergoing laparoscopy. Most of the UUSs were stage I (89.58%, which occurred more commonly (56.25% in women aged 40–49. Abnormal uterine bleeding (39.58% was the main clinical manifestation. Rapidly growing pelvic masses (12.5%, rich blood flow signals (18.75%, and degeneration of uterine fibroids (18.75% prompted by ultrasonography may suggest the possibility of UUSs. The margins of most UUSs (93.75% were regular, which may cause UUSs to be misdiagnosed as uterine fibroids. Fifteen cases underwent magnetic resonance imaging examinations. Approximately 73.33% showed heterogeneous and hypointense signal intensity on T1-weighted images, and 80% showed intermediate-to-high signal intensity on T2-weighted images, with necrosis and hemorrhage in 40% of cases. After contrast administration, 80% presented early heterogeneous

    We report our experience with a preterm infant with severe hemolytic jaundice who required exchange transfusion just after birth. The patient was negative for alloimmune hemolysis as a result of maternal-fetal blood type incompatibility, and tests for inherited defects in erythrocyte metabolism, membrane function, and hemoglobin synthesis were normal. We also performed a bone marrow examination, but could not identify the cause of hemolysis. The patient had several other complications, including porencephaly, epilepsy, elevated serum levels of creatine kinase, and persistent microscopic hematuria. Later, we detected a genetic mutation in COL4A1, which was recently found to be associated with hemolytic anemia. We therefore believe that all of the patient's clinical features, including hemolytic anemia, were due to the mutation in COL4A1. Genetic testing for COL4A1 mutations is recommended in neonates who exhibit hemolytic disease of unknown etiology, especially when other complications compatible with COL4A1-related disorders are present.

    Rawan Abdulhameed Edan

    Full Text Available Microglia activation results in release of proinflammatory molecules including cytokines, which contribute to neuronal damage in the central nervous system (CNS if not controlled. Tetracycline antibiotics such as minocycline inhibit microglial activation and cytokine expression during CNS inflammation. In the present study we found that administration of chemically modified tetracycline-3 (COL-3, inhibits lipopolysaccharide (LPS-induced microglial and p38 MAPK activation, as well as the increase in TNF-α, but not IL-1β expression, in the brains of BALB/c mice. COL-3 has been described to have no antibacterial activity. We observed that COL-3 had no activity against a Gram-negative bacteria, Escherichia coli; however surprisingly, COL-3 had antibacterial activity against a Gram-positive bacteria Staphylococcus aureus, with a minimum inhibitory concentration of 1 mg/ml. Our data show that COL-3 has some antibacterial activity against S. aureus, inhibits LPS-induced neuroinflammation, and displays potential as a therapeutic agent for treatment of conditions involving CNS inflammation.

    Three ColV virulence plasmids carrying antibiotic resistance genes were assembled from draft genome sequences of commensal ST95, ST131, and ST2705 Escherichia coli isolates from healthy Australians. Plasmids pCERC4, pCERC5, and pCERC9 include almost identical backbones containing FII-2 and FIB-1 replicons and the conserved ColV virulence region with an additional ColIa determinant. Only pCERC5 includes a complete, uninterrupted F-like transfer region and was able to conjugate. pCERC5 and pCERC9 contain Tn1721, carrying the tet(A) tetracycline resistance determinant in the same location, with Tn2 (bla TEM ; ampicillin resistance) interrupting the Tn1721 in pCERC5. pCERC4 has a Tn1721/Tn21 hybrid transposon carrying dfrA5 (trimethoprim resistance) and sul1 (sulfamethoxazole resistance) in a class 1 integron. Four FII-2:FIB-1 ColV-ColIa plasmids in the GenBank nucleotide database have a related transposon in the same position, but an IS26 has reshaped the resistance gene region, deleting 2,069 bp of the integron 3'-CS, including sul1, and serving as a target for IS26 translocatable units containing bla TEM , sul2 and strAB (streptomycin resistance), or aphA1 (kanamycin/neomycin resistance). Another ColV-ColIa plasmid containing a related resistance gene region has lost the FII replicon and acquired a unique transfer region via recombination within the resistance region and at oriT. Eighteen further complete ColV plasmid sequences in GenBank contained FIB-1, but the FII replicons were of three types, FII-24, FII-18, and a variant of FII-36.

    Postpartum changes in uterine shape, architecture, echogenicity and diameter were determined during the serial examinations of five beagle bitches. During postpartum Week 1, the uterine horns were tubular structures composed of multiple layers of various echogenicity and had multiple, discrete enlargements with hypoechoic centers at placental sites. Diameters ranged from 1.1 to 3.8 cm at placental site enlargements, and 0.5 to 1.4 cm between enlargements. Uterine involution appeared to be completed by 15 wk post partum. At 15 weeks the uterine horns of each dog were uniform hypoechoic, tubular structures without enlargements and had a reduced diameter of 0.3 to 0.6 cm. These ultrasonographic findings are similar to previously reported gross and light microscopic descriptions of canine uterine involution.

    Uterine arteriovenous malformation (AVM) is a rare cause of vaginal bleeding and miscarriage. We report two cases of uterine AVMs in patients with a history of complex congenital heart disease, an association that has not been previously described. Both patients were treated by selective uterine artery embolization, a minimally invasive therapy that has revolutionized the management of uterine AVMs, thus offering an alternative to conventional hysterectomy.

    The Col1a2(+/G610C) knock-in mouse, models osteogenesis imperfecta in a large old order Amish family (OOA) with type IV OI, caused by a G-to-T transversion at nucleotide 2098, which alters the gly-610 codon in the triple-helical domain of the α2(I) chain of type I collagen. Mineral and matrix properties of the long bones and vertebrae of male Col1a2(+/G610C) and their wild-type controls (Col1a2(+/+)), were characterized to gain insight into the role of α2-chain collagen mutations in mineralization. Additionally, we examined the rescuability of the composition by sclerostin inhibition initiated by crossing Col1a2(+/G610C) with an LRP(+/A214V) high bone mass allele. At age 10-days, vertebrae and tibia showed few alterations by micro-CT or Fourier transform infrared imaging (FTIRI). At 2-months-of-age, Col1a2(+/G610C) tibias had 13% fewer secondary trabeculae than Col1a2(+/+), these were thinner (11%) and more widely spaced (20%) than those of Col1a2(+/+) mice. Vertebrae of Col1a2(+/G610C) mice at 2-months also had lower bone volume fraction (38%), trabecular number (13%), thickness (13%) and connectivity density (32%) compared to Col1(a2+/+). The cortical bone of Col1a2(+/G610C) tibias at 2-months had 3% higher tissue mineral density compared to Col1a2(+/+); Col1a2(+/G610C) vertebrae had lower cortical thickness (29%), bone area (37%) and polar moment of inertia (38%) relative to Col1a2(+/+). FTIRI analysis, which provides information on bone chemical composition at ~7μm-spatial resolution, showed tibias at 10-days did not differ between genotypes. Comparing identical bone types in Col1a2(+/G610C) to Col1a2(+/+) at 2-months-of-age, tibias showed higher mineral-to-matrix ratio in trabeculae (17%) and cortices (31%). and in vertebral cortices (28%). Collagen maturity was 42% higher at 10-days-of-age in Col1a2(+/G610C) vertebral trabeculae and in 2-month tibial cortices (12%), vertebral trabeculae (42%) and vertebral cortices (12%).

    Variations in uterine bleeding, termed abnormal uterine bleeding, occur commonly among women and often are physiologic in nature with no significant consequences. However, abnormal uterine bleeding can cause significant distress to women or may signify an underlying pathologic condition. Most women experience variations in menstrual and perimenstrual bleeding in their lifetimes; therefore, the ability of the midwife to differentiate between normal and abnormal bleeding is a key diagnostic skill. A comprehensive history and use of the PALM-COEIN classification system will provide clear guidelines for clinical management, evidence-based treatment, and an individualized plan of care. The purpose of this Clinical Bulletin is to define and describe classifications of abnormal uterine bleeding, review updated terminology, and identify methods of assessment and treatment using a woman-centered approach. © 2016 by the American College of Nurse-Midwives.

  2. Uterine fibroid management: from the present to the future

    2016-01-01

    Abstract Uterine fibroids (also known as leiomyomas or myomas) are the most common form of benign uterine tumors. Clinical presentations include abnormal bleeding, pelvic masses, pelvic pain, infertility, bulk symptoms and obstetric complications. Almost a third of women with leiomyomas will request treatment due to symptoms. Current management strategies mainly involve surgical interventions, but the choice of treatment is guided by patient's age and desire to preserve fertility or avoid ‘radical’ surgery such as hysterectomy. The management of uterine fibroids also depends on the number, size and location of the fibroids. Other surgical and non-surgical approaches include myomectomy by hysteroscopy, myomectomy by laparotomy or laparoscopy, uterine artery embolization and interventions performed under radiologic or ultrasound guidance to induce thermal ablation of the uterine fibroids. There are only a few randomized trials comparing various therapies for fibroids. Further investigations are required as there is a lack of concrete evidence of effectiveness and areas of uncertainty surrounding correct management according to symptoms. The economic impact of uterine fibroid management is significant and it is imperative that new treatments be developed to provide alternatives to surgical intervention. There is growing evidence of the crucial role of progesterone pathways in the pathophysiology of uterine fibroids due to the use of selective progesterone receptor modulators (SPRMs) such as ulipristal acetate (UPA). The efficacy of long-term intermittent use of UPA was recently demonstrated by randomized controlled studies. The need for alternatives to surgical intervention is very real, especially for women seeking to preserve their fertility. These options now exist, with SPRMs which are proven to treat fibroid symptoms effectively. Gynecologists now have new tools in their armamentarium, opening up novel strategies for the management of uterine fibroids. PMID

    2013-01-01

    Objective: To evaluate the results of uterine fibroid embolisation as a treatment option for symptomatic uterine fibroids in the local population. Methods: The retrospective study was done at the Department of Diagnostic and Interventional Radiology, Shifa International Hospital, Islamabad, and comprised records of 12 patients with symptomatic uterine fibroids who had undergone uterine fibroid embolisation with the use of polyvinyl alcohol between May 2008 and July 2012. All of these patients had been assessed by a gynaecologist. Pre-embolisation workup was done by pelvic Magnetic Resonance Imaging. A detailed questionnaire was prepared to assess clinical improvement and interval change in fibroid size on follow-up imaging. Results: A technically successful embolisation was done in all patients. All patients experienced immediate post-procedure pain, but responded to conservative treatment. Clinical follow-up showed a significant reduction in symptoms within six months of the procedure, with 88% improvement in menorrhagia and 100% improvement in pain. Follow-up imaging showed reduction in fibroid sizes ranging from 17-63%. Two patients developed infection, which is a known complication of this procedure. Conclusion: Uterine fibroid embolisation is a well-recognised treatment option for symptomatic uterine fibroids. Ascertaining its long-term results in our local population will, however, require additional studies with larger patient populations. (author)

    Objective: to observe the origin site, anatomic features of uterine artery with 3D DSA and to discuss the optimal projection position in order to improve the success rate of super-selective catheterization of uterine artery. Methods: Prospective pelvic angiography was performed in 42 adult females (a total of 84 uterine arteries). 3D DSA was carried out with 206 ° rotation. 3D reconstruction of the obtained images was performed and the angiographic manifestations of the uterine artery were analyzed. The optimal projection position for the displaying of uterine artery was discussed. The quality of images obtained with the projection angle of 15 °-25 °, 25 °-35 ° and 35 °-45 ° was determined and the results were compared with each other. Results: The orifices of all 84 uterine arteries could be well demonstrated on 3D DSA images. The uterine artery was originated from the anterior trunk of internal iliac artery (n=58, 69%), from main stem of internal iliac artery (n=16, 19.1%), from internal pudenda artery (n=8, 9.5%) and from inferior gluteal artery (n=2, 2.4%). The best projection position to show the opening and route of the uterine artery was contralateral oblique view of 25-35 degrees (P<0.05). Conclusion: 3D DSA can clearly display the anatomy of the uterine artery, which is very helpful for the management of super-selective catheterization of uterine artery. The optimal projection position for uterine artery is contralateral oblique view of 25-35 degrees. (authors)

    Full Text Available Background. Uterine leiomyosarcoma is a rare and aggressive gynecologic malignancy with an overall poor prognosis. Lungs, bones, and brain are common sites of metastases of uterine leiomyosarcoma. Metastases of uterine leiomyosarcoma to the small bowel are extremely rare, and only four case reports have been published to date. Case presentation. A 55-year-old Saudi woman diagnosed with a case of uterine leiomyosarcoma treated with total abdominal hysterectomy (TAH and bilateral salpingooophorectomy (BSO presented in emergency room after sixteen months with acute abdomen. Subsequent work-up showed a jejunal mass for which resection and end-to-end anastomosis were performed. Biopsy confirmed the diagnosis of small bowel metastasis from uterine leiomyosarcoma. Further staging work-up showed wide spread metastasis in lungs and brain. After palliative cranial irradiation, systemic chemotherapy based on single agent doxorubicin was started. Conclusion. Metastatic leiomyosarcoma of small bowel from uterine leiomyosarcoma is a rare entity and is sign of advanced disease. It should be differentiated from primary leiomyosarcoma of small bowel as both are treated with different systemic chemotherapeutic agents.

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

    Full Text Available Introduction: Abnormal uterine bleeding is a common condition affecting women of reproductive age that has significant social and economic impact. Dysfunctional uterine bleeding (DUB is defined as abnormal uterine bleeding in the absence of organic disease. Dysfunctional uterine bleeding is one of the most commonly encountered gynaecological problems. Objectives: This study is done to evaluate the histopathological pattern of the endometrial biopsies of patients with dysfunctional uterine bleeding and its correlation with clinical data. Methods: The present prospective study included evaluation of 208 cases of dysfunctional uterine bleeding in the Department of Pathology, B. J. Medical College, Ahmedabad over a period of 10 months, from January 2017 to October 2017. Women presenting with abnormal uterine bleeding were included in the study. Those women in which bleeding is secondary to systemic causes, organic causes and due to cervical and vaginal causes were excluded. The specimens were processed, embedded and cut into sections of 3-4 microns. The histopathological patterns were studied. Results: Age distribution varied from 18 years to 70 years, majority of the patients were between 21 to 30 years. Among the cases of DUB, proliferative phase accounted for 66.3% and secretory phase accounted for 21.3%. 18 cases (8.6% of atrophic endometrium, four cases (1.9% of irregular shedding and two cases of luteal phase insufficiency were received. Conclusion: Dysfunctional uterine bleeding is a common and debilitating condition in women of reproductive age. Endometrial biopsy could be effectively used as the first diagnostic step in DUB and thus ensures correct management.

  12. Variação do volume de gotas de colírios lubrificantes disponíveis no mercado brasileiro

    Vitorugo Silvestre Nascimento

    Full Text Available RESUMO Objetivo: Avaliar a variação intra e interexaminadores do volume de gotas dispensados de frascos de colírios lubrificantes disponíveis no mercado. Métodos: Foram estudados cinco frascos de colírios lubrificantes e dezenove voluntários participaram deste estudo. A massa média de gotas de 20µl dos colírios foi obtida utilizando micropipeta e balança de precisão e como padrão para comparação com a massa das gotas obtidas pelos voluntários. Cinco gotas de cada frasco foram pesadas individualmente com o tubo de colírio perpendicular à balança, usando o primeiro e segundo dedos da mão direita, de forma que a pressão fosse aplicada somente no meio do frasco. Os experimentos foram realizados em uma sala climatizada a temperatura ambiente (21±1°C. Resultados: Todos os frascos de colírios apresentaram variação estatisticamente significante das massas das gotas obtidas pelos examinadores quando comparadas com a massa média padrão de 0,0182±0,0014g, com exceção da comparação entre os dados do colírio A com o colírio D, que não apresentou variação estatisticamente significante. Conclusão: O presente estudo demonstra a ausência de uniformidade das gotas dispensadas pelos frascos de colírios disponíveis no mercado e a sua inadequação à real necessidade, uma vez que as gotas dispensadas são maiores do que o indicado. Esse fato torna-se um problema quando se trata de período de tratamento prolongado, especialmente com colírios dispendiosos como os indicados para a terapêutica do glaucoma. Nesse sentido, a padronização das gotas de colírios se faz necessária.

    Uterine fibroids are common tumors of the female pelvis. Uterine artery embolization (UAE) is an effective treatment of symptomatic uterine leiomyoma in the appropriate candidates, reducing or eliminating leiomyoma-related symptoms of bleeding, bulk, and/or pain. Magnetic resonance imaging (MRI) can be used to assess women with symptoms potentially attributable to uterine leiomyomas, and help to determine who is an appropriate candidate for UAE. Because of soft tissue characterization, multiplanar imaging capabilities, and enhancement, MR imaging not only accurately detects and characterizes uterine leiomyomas but also may predict who will benefit from the embolization. MRI ability to detect coexistent uterine or pelvic pathology may change the diagnosis and treatment management of patients being evaluated for UAE

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

    2015-12-01

    An ongoing debate over the last two decades has focused on whether fertility treatment in women may lead to an increased risk of developing uterine cancer over a period of time. Uterine cancer (including mainly endometrial carcinoma and the less common uterine sarcoma) is the commonest reproductive tract cancer and the fourth commonest cancer in women in the UK. Our objective was to assess the association between fertility drugs used in the treatment of female infertility (both as an independent therapy and during in vitro fertilization cycles) and the development of uterine cancer. A literature search was performed using Medline, Embase, Cochrane Library and Google Scholar databases for comparative studies until December 2014 to investigate a clinical significance of fertility treatment on the incidence of developing uterine cancer. General and MESH search headings, as well as the 'related articles' function were applied. All comparative studies of 'fertility treatment' versus 'non-fertility treatment' reporting the incidence of uterine cancer as an outcome were included. Uterine cancer incorporated the following terms: uterine cancer, uterine body tumours, uterine sarcomas and endometrial cancers. The primary outcome of interest was the uterine cancer incidence in all 'fertility treatment' versus 'non-fertility treatment' patient groups. Secondary outcomes of interest were: (a) uterine cancer incidence in 'IVF' versus 'non-IVF' patient groups; and (b) uterine cancer incidence according to type of fertility drug used. Odds ratio was the summary statistic. Random-effects modelling, graphical exploration and sensitivity analysis were used to evaluate the consistency of the calculated treatment effect. We included six studies in our final analysis, which comprised 776,224 patients in total. Of these, 103,758 had undergone fertility treatment and 672,466 had not. There was 100% agreement between the two reviewers regarding the data extraction. All the studies

    2007-01-01

    We studied the human melanoma black-45 (HMB-45) reactivity in 25 uterine leiomyosarcomas including 23 conventional and 2 myxoid variants. Eleven tumors were poorly differentiated, and 14 were well to moderately differentiated. Nine uterine leiomyosarcomas labeled with HMB-45 in 10% or less of the tumor cells. Six were poorly differentiated and 3 were well differentiated. Our study indicates that 36% of conventional leiomyosarcomas focally express HMB-45. HMB-45 reactivity was more common in the poorly differentiated than in the well-differentiated group of leiomyosarcomas. In light of our findings and of those recently reported in the literature, we believe that the term PEComa should not be used for uterine leiomyosarcomas with clear cells or for conventional leiomyosarcomas that stain positively with HMB-45.

  3. Imaging before and after uterine artery embolization

    2008-01-01

    Percutaneous catheter-based embolization treatment of symptomatic uterine fibroids has evolved into the most widely used alternative therapeutic approach to surgical treatment worldwide. Uterine artery embolization (UAE) induces infarction of leiomyomas, resulting in ischemic necrosis, hyaline degeneration, and size reduction with resolution of associated symptoms. Published experience suggests that UAE is an effective and reliable option for treating uterine fibroids with high patient satisfaction. Magnetic resonance imaging (MRI) is superior to ultrasonography for determining the site, size and number of fibroids, which is important for establishing the indication for UAE. Other potential advantages of MRI include the option of performing MR angiography (MRA) and obtaining contrast-enhanced images for monitoring the outcome of UAE and assessing possible complications after UAE.

    Congenital uterine anomalies are associated with the highest incidence of reproductive failure and obstetric complications. This study aimed to summarize the clinical characteristics and prenatal outcome of pregnancy in women with congenital uterine malformations. This retrospective study evaluated the fertility and obstetric outcome of 116 inpatients with uterine malformations with pregnancy in Peking University Third Hospital from June 1998 to June 2009. A total of 270 randomly selected pregnant women with a previously confirmed normally shaped uterus as a control group. Student's t test and analysis of variance (ANOVA) were used to compare means for normally distributed variables. The analysis was carried out using the SPSS. Among 21 961 deliveries in Peking University Third Hospital, 116 (0.45%) were in women with uterine anomalies. A septate uterus was present in 43 (37.1%) and the uterus didelphys in 28 (24.2%) of the 116 women identified. Bicornuate uterus, arcuate and unicomate uterus were observed in 12 (10.3%), 18 (15.5%) and 15 (12.9%) patients, respectively. Patients with uterine anomalies had significantly higher rates of malpresentation (38.8%), preterm delivery (19.8%), and cesarean section (78.5%) compared with the group of women with a normal uterus. Patients with uterine anomalies had significantly lower mean birth-weight neonates and a significantly higher incidence of small for gestationalage (SGA) neonates; women with uterus didelphys more frequently required infertility treatment than patients with other uterine anomalies (P unicorns (P < 0.05). Women with congenital uterinemal formation usually have higher incidence of complications during pregnancy and delivery. A septate uterus appears to be associated with poorer obstetric outcomes.

    Even if the Sein Island emits less CO 2 emissions than 700 vehicles, the Government set an objective of 50 per cent for renewable energy production within its multi-year energy planning (PPE). The objectives of the authors is herein to analyse the credibility of these PPE objectives, more particularly as far as electric power autonomy is concerned. They used available and precise data related to the island's energy consumption. They show that this 50 per cent coverage can indeed be reached, but with investments which are not justified when the population size and current resulting pollution are considered. They also outline that diesel engines will still be used from time to time, and that their emissions will not even be reduced as diesel units will not operate in optimal regime. Therefore, they regret that such objectives have been imposed to the island without any detailed preliminary study

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

    We present the case of a 37-year-old nulliparous woman in whom acute massive uterine bleeding during dienogest therapy was successfully treated using intrauterine balloon tamponade. Abnormal uterine bleeding and several cases of profuse bleeding causing severe anemia in association with dienogest therapy have been reported, but this is the first reported case involving hypovolemic shock. While successful control of postpartum hemorrhage with intrauterine balloon tamponade has been well described, applications for non-obstetric bleeding, particularly in the presence of underlying diseases, such as adenomyosis, have only rarely been reported. This procedure can be easily, promptly, and safely implemented without analgesia, anesthesia, or laparotomy; it can be used with a minimally dilated external cervical os or narrow uterine cavity; and it can preserve fertility. © 2012 The Authors.

    Full Text Available RNA trans-splicing represents an auspicious option for the correction of genetic mutations at RNA level. Mutations within COL7A1 causing strong reduction or absence of type VII collagen are associated with the severe skin blistering disease dystrophic epidermolysis bullosa. The human COL7A1 mRNA constitutes a suitable target for this RNA therapy approach, as only a portion of the almost 9 kb transcript has to be delivered into the target cells. Here, we have proven the feasibility of 5′ trans-splicing into the Col7a1 mRNA in vitro and in vivo. We designed a 5′ RNA trans-splicing molecule, capable of replacing Col7a1 exons 1–15 and verified it in a fluorescence-based trans-splicing model system. Specific and efficient Col7a1 trans-splicing was confirmed in murine keratinocytes. To analyze trans-splicing in vivo, we used gene gun delivery of a minicircle expressing a FLAG-tagged 5′ RNA trans-splicing molecule into the skin of wild-type mice. Histological and immunofluorescence analysis of bombarded skin sections revealed vector delivery and expression within dermis and epidermis. Furthermore, we have detected trans-spliced type VII collagen protein using FLAG-tag antibodies. In conclusion, we describe a novel in vivo nonviral RNA therapy approach to restore type VII collagen expression for causative treatment of dystrophic epidermolysis bullosa.

  11. Impact of boat generated waves over an estuarine intertidal zone of the Seine estuary (France)

    Water movements in macrotidal estuaries are controlled by the tidal regime modulated seasonally by the fluvial discharge. Wind effect on hydrodynamics and sediment transport is also reported at the mouth. Besides estuaries are frequently man altered our knowledge on the human impact on hydrodynamics and sediment transport is less extended. As an example on the Seine estuary (France) port authorities have put emphasis on facilitating economic exchanges by means of embankment building and increased dredging activity over the last century. These developments led to secure sea vessel traffic in the Seine estuary but they also resulted in a change of estuarine hydrodynamics and sediment transport features. Consequences of boat generated waves are varied: increased water turbidity and sediment transfer, release of nutrient and contaminants in the water column, harmful to users, ecosystems and infrastructures generating important maintenance spending. The aim of this study is to analyse the impact of boat generated waves on sediment transport over an intertidal area. The studied site is located on the left bank in the fluvial part of the Seine estuary. On this site the maximum tidal range ranges between 1.25 and 3.5m respectively during neap and spring tide. The sampling strategy is based on continuous ADV acquisition at 4Hz coupled with turbidimeter and altimeter measurements (1 measurement every minute) in order to decipher sediment dynamics during one year. Our results indicate that sediment dynamics are controlled by river flow while medium term scale evolution is dependent on tidal range and short term dynamics on sea-vessels waves. 64% of boat passages generated significant sediment reworking (from few mm.min-1 to 3cm.min-1). This reworking rate is mainly controlled by two parameters: (i) water height on the site and (ii) vessels characteristics; in particular the distance between seabed and keel that generate a Bernoulli wave (with maximum amplitude of 0.6m

    Uterine fibroids, also known as leiomyomas, are the most common uterine neoplasms. Although benign, they can be associated with significant morbidity and are the commonest indication for hysterectomy. They are often discovered incidentally when performing imaging for other reasons. Usually first identified with US, they can be further characterized with MRI. They are usually easily recognizable, but degenerate fibroids can have unusual appearances. Knowledge of the different appearances of fibroids on imaging is important as it enables prompt diagnosis and thereby guides treatment. (authors)

    Uterine transplantation (UTn) has been proposed as a treatment option for women diagnosed with absolute uterine factor infertility (AUFI) and who are willing to bear their own child. AUFI renders a woman 'unconditionally infertile'. For AUFI women in general, UTn may offer a way to re-discover their own femininity through the restoration of fertility. Thus, when faced with a patient who may undergo UTn, the 'holistic approach' takes on an extra meaning. This is because the psychological element is two-sided for these patients. On one side lies the psychology of infertility, and on the other and equally important, is the substantially higher prevalence of psychiatric disorders in transplant candidates and recipients than in the general population. However, the psychology of a potential recipient of a uterine graft in order to bring about fertility has not been adequately explored or reviewed scientifically. We have presented here an outline of the areas which should be included in a psychological assessment for patients wishing to undergo UTn.

    2011-01-01

    Purpose: To investigate the value of diffusion-weighted MR imaging (DWI), especially apparent diffusion coefficient (ADC) in the differentiation of uterine adenomyosis and leiomyoma. Materials and methods: 17 patients with uterine leiomyoma and 22 patients with uterine adenomyosis underwent diffusion-weighted imaging (DWI) in addition to routine MR imaging. The ADC values, as well as ADC D-value (defined as the ADC value of high signal intensive foci minus the ADC value of lesion tissues the difference in value), were measured and compared to investigate whether they could help in the differentiation of uterine adenomyosis and leiomyoma. Histopathologic examination was conducted as the golden standard. Results: For high signal intensive foci within the lesions, uterine adenomyosis demonstrated significantly lower mean ADC value than uterine leiomyoma (1.582 vs. 2.122 x 10 -3 mm 2 /s, P = 0.001). For lesion tissues, uterine adenomyosis demonstrated significantly higher mean ADC value than uterine leiomyoma (1.214 vs. 0.967 x 10 -3 mm 2 /s, P = 0.001). However, there was overlap between uterine adenomyosis and leiomyoma in both measurements. Mean ADC D-value was significantly lower in uterine adenomyosis than in uterine leiomyoma (0.369 vs. 1.096 x 10 -3 mm 2 /s, P = 0.000). ADC D-value had no overlap between uterine adenomyosis and leiomyoma. Conclusion: DWI can be applied for the further differentiation of uterine adenomyosis and leiomyoma, in addition to routine MR imaging. ADC D-value may be a more useful tool than ADC value in the differentiation.

    The aim of this study is to define a new method of manipulating the uterus during laparoscopic hysterectomy. A total laparoscopic hysterectomy (TLH) with the newly defined technique was performed in 29 patients between July 2016 and July 2017. In this new technique, the uterus was bound from uterine corpus and fundus like a bridle with polyester tape, to allow abdominal manipulation. The technique was successfully performed at the first attempt in 93.1% of cases. It was repeated in two cases (6.9%) since the polyester tape departed away from the uterus at the first attempt. The mean application time was 11.2 min. The vaginal manipulator was not required in any of the cases. There were no intraoperative complications. In conclusion, this method has the advantages of not requiring any vaginal manipulator, reducing the number of people required during operation, permitting a near maximum manipulation of the uterus in all three dimensions, and giving the control of these manipulations directly to the surgeon. On the other hand, the technique also has some inadequacies which should be discussed and improved on in the future. Impact of statement What is already known on this subject? In a laparoscopic hysterectomy, manipulation of the uterus is essential for anatomical dissection of the regions and completion of the operation without complications. An ideal uterine manipulator is defined as inexpensive, as convenient, fast and suitable for injecting solutions, removing the need for an assistant and most importantly offering the most suitable range of motion. In this study, we describe a new and different technique (rein technique) allowing the abdominal manipulation of the uterus in a laparoscopic hysterectomy and discuss the advantages and disadvantages of this method. What do the results of this study add? The procedure was easily accomplished in most patients. We did not need to use an extra uterine manipulator in any of the cases. What are the implications of these

    Abnormal uterine bleeding is a common presenting complaint in gyanecology out patient department. Histopathological evaluation of the endometrial samples plays a significant role in the diagnosis of abnormal uterine bleeding. This study was carried out to determine the histopathological pattern of the endometrium in women of various age groups presenting with abnormal uterine bleeding. Endometrial biopsies and curettings of patients presenting with abnormal uterine bleeding was retrospectively studied. A total of 403 endometrial biopsies and curettings were analyzed. The age of the patients ranged from 18 to 70 years. Normal cyclical endometrium was seen in 165 (40.94%) cases, followed by 54 (13.40%) cases of disordered proliferative endometrium and 44 (10.92%) cases of hyperplasia. Malignancy was seen in 10 (2.48%) cases. Hyperplasia and malignancy were more common in the perimenopausal and postmenopausal age groups. Histopathological examination of endometrial biopsies and curettings in patients presenting with abnormal uterine bleeding showed a wide spectrum of changes ranging from normal endometrium to malignancy. Endometrial evaluation is specially recommended in women of perimenopausal and postmenopausal age groups presenting with AUB, to rule out a possibility of any preneoplastic condition or malignancy.

    Full Text Available Catch biomass and time-trend perception of Beach seine fishery were studied during 2015, from four different sites in East Java: Padikde Madura, Santan Island Banyuwangi, Prigi Beach Trenggalek, and Dangkal Beach Pacitan. The study aimed to assess the impact of recently Ministerial Decree (No. 2/2015 on this particular fishery. Catch biomass was analyzed based on swept area method. Time trend perception was traced back from fishermen in relation to reduced catch biomass, catch size, habitat degradation, and income contribution from the fishery. The results showed that Beach Seines in East Java are considerably subsistence. It swept fixed-bottom habitats of 1–9 ha. Average catch biomass for all sites was 15±19.4 kg trip-1. With low price of fish catch, fishermen cannot place down their family income solely from this livelihood. Beach seine is more as to maintain tradition of subsistence. Fishermen clearly observed the reduced in catch biomass and catch size compared to what it used to be (±30 years ago. With very low contribution to total catch in the region, negligible impact to habitat degradation, and consumed no fuel subsidy, it is no real reason to include this gear in general ban through Ministerial Decree of Marine Affairs and Fisheries.

    Full Text Available 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 A 45-year-old premenopausal woman was referred to our clinic due to recurring symptoms of uterine fibroids, nine years after a uterine artery embolization (UAE. At the time of screening, the patient presented with bilateral impairment and narrowing of the uterine arteries, which increased the risk of arterial perforation during repeated UAE procedures. The patient was subsequently referred for magnetic resonance imaging-guided focused ultrasound surgery (MRgFUS treatment. Following the treatment, the patient experienced a significant improvement in symptoms (symptom severity score was reduced from 47 to 12 by 1 year post-treatment. MR images at 3 months showed a 49% decrease in fibroid volume. There were no adverse events during the treatment or the follow-up period. This case suggests that MRgFUS can be an effective treatment option for patients with recurrent fibroids following previous UAE treatment.

    Objective: To investigate the long-term efficiency and safety of trans-catheter uterine artery embolization using lipiodol-pingyingmycin emulsion (LPE-TUAE) for uterine fibroids. Methods: Two hundred and forty-three patients with uterine fibroids were treated by LPE-TUAE. Fourteen of them underwent hysterectomy or myomectomy 3 days to 6 months after LPE-TUAE. The specimens were studied pathologically. Another 229 patients were followed up for 1 to 4 years to observe the long-term outcomes. Results: Menorrhagia became normal or improved markedly in 96.0% (193/201). Lumbago and lower abdominal pain disappeared or relieved markedly in 949% (94/99). Bulk-related symptoms disappeared or lessened markedly in 96.0% (48/50). Ultrasound revealed that the average decreased rate in the largest fibroid volume were 60.7% at 1 year, 63.3% at 2 year, 65.6% at 3 year and 67.4% at 4 year after embolization, and the average decreased rate in the largest uterine volume were 49.6% at 1 year, 54.3% at 2 year, 55.2% at 3 year and 57.1% at 4 year after embolization. Reoccurrence rate of myoma was 10.8% 3-4 year after embolization. No significant difference was found in hormone level between pre- and post-embolization. Pathological studies of specimens showed that lipiodol was only accumulated in fibroids and was not seen in myometrium. Spotty necrosis 2 weeks after embolization and extensive patchy necrosis 3 weeks after embolization were occurred in fibroids. Necrosis was not showed in myometrium. No serious complications occurred. Conclusion: LPE-TUAE possesses a good long-term effectiveness for uterine fibroids, which doesn't cause the damage on ovarian function and normal myometrium or serious complications. (authors)

    Uterine rupture is an obstetric calamity with surgery as its management mainstay. Uterine repair without tubal ligation leaves a uterus that is more prone to repeat rupture while uterine repair with bilateral tubal ligation (BTL) or (sub)total hysterectomy predispose survivors to psychosocial problems like marital disharmony. This study aims to evaluate obstetricians' perspectives on surgical decision making in managing uterine rupture. A questionnaire-based cross-sectional study of obstetricians at the 46th annual scientific conference of Society of Gynaecology and Obstetrics of Nigeria in 2012. Data was analysed by descriptive and inferential statistics. Seventy-nine out of 110 obstetricians (71.8%) responded to the survey, of which 42 (53.2%) were consultants, 60 (75.9%) practised in government hospitals and 67 (84.8%) in urban hospitals, and all respondents managed women with uterine rupture. Previous cesarean scars and injudicious use of oxytocic are the commonest predisposing causes, and uterine rupture carries very high incidences of maternal and perinatal mortality and morbidity. Uterine repair only was commonly performed by 38 (48.1%) and uterine repair with BTL or (sub) total hysterectomy by 41 (51.9%) respondents. Surgical management is guided mainly by patients' conditions and obstetricians' surgical skills. Obstetricians' distribution in Nigeria leaves rural settings starved of specialist for obstetric emergencies. Caesarean scars are now a rising cause of ruptures. The surgical management of uterine rupture and obstetricians' surgical preferences vary and are case scenario-dependent. Equitable redistribution of obstetricians and deployment of medical doctors to secondary hospitals in rural settings will make obstetric care more readily available and may reduce the prevalence and improve the outcome of uterine rupture. Obstetrician's surgical decision-making should be guided by the prevailing case scenario and the ultimate aim should be to avert

    The uterine electrical activity is an efficient parameter to study the uterine contractility. In order to understand the ionic mechanisms responsible for its generation, we aimed at building a mathematical model of the uterine cell electrical activity based upon the physiological mechanisms. First, based on the voltage clamp experiments found in the literature, we focus on the principal ionic channels and their cognate currents involved in the generation of this electrical activity. Second, we provide the methodology of formulations of uterine ionic currents derived from a wide range of electrophysiological data. The model is validated step by step by comparing simulated voltage-clamp results with the experimental ones. The model reproduces successfully the generation of single spikes or trains of action potentials that fit with the experimental data. It allows analyzing ionic channels implications. Likewise, the calcium-dependent conductance influences significantly the cellular oscillatory behavior.

    Endometrial remodeling is a physiological process involved in the gynecological disease, endometriosis. Tissue remodeling is directed by uterine fibroblast production of matrix metalloproteinases (MMPs). Several MMPs are regulated directly by the protein extracellular matrix metalloproteinase inducer (EMMPRIN) and also by proinflammatory cytokines such as interleukin (IL)1-α/β. We hypothesized that human uterine epithelial cells (HESs) secrete intact EMMPRIN to stimulate MMPs. Microvesicles from HES cell-conditioned medium (CM) expressed intact EMMPRIN protein. Treatment of HES cells with estradiol or phorbyl 12-myristate-13-acetate increased the release of EMMPRIN-containing microvesicles. The HES CM stimulated MMP-1, -2, and -3 messenger RNA levels in human uterine fibroblasts (HUFs) and EMMPRIN immunodepletion from HES-cell concentrated CM reduced MMP stimulation (P EMMPRIN, in response to ovarian hormones, proinflammatory cytokines as well as activation of protein kinase C.

    Objective: To evaluate the quality of life in women with uterine leiomyoma after treatment by uterine arterial embolization. Methodes: 118 patients of uterine leiomyoma were treated by uterine arterial embolization (UAE) from January 2003 to March 2005. The quality of life was measured by a fibroid specific symptom and HRQOL questionnaire pre-and post-embolization. Patients satisfaction was surveyed together with decrease of fibroids' mass measurement. Results: The decrease of fibroid size and uterine volume were 49.6% and 45.2% at 6 months after embolization with simultaneously obvious improvement of clinical symptoms. The scores of quality of life obviously improved in all follow-up subscales (P<0.001). No amenorrhea occurred during the period of observation with more than 60% of respondents acknowledging the positive improvement in fibroid-related symptoms though UAE; and 80% would probably or definitely take UAE as the first choice of treatment again. Conclusion: The treatment of symptomatic leiomyomas by UAE can improve the quality of life dramatically with a promising satisfaction. (authors)

    Objective: To discuss the feasibility and safety of uterine artery chemoembolization in treating cesarean section scar pregnancy. Methods: During the period of Jun. 2005-Jun. 2010, uterine artery chemoembolization was performed in 130 patients with cesarean section scar pregnancy in authors' hospital. Via bilateral uterine arteries 100-150 mg MTX and 80 000 u Gentamycin were infused separately, which was followed by the embolization of bilateral uterine arteries with Gelfoam. Of the total 130 patients,coexisted leiomyoma was found in 23 and embolization therapy with PVA microspheres was employed. Curettage of uterus was carried out within 24-72 hours after the procedure. Results: The success rate of bilateral uterine artery chemoembolization was 100%. The blood loss during curettage procedure was 12-110 ml (mean 28.5 ml). No serious complications occurred. Conclusion: The uterine artery chemoembolization is an effective and safe treatment for cesarean section scar pregnancy. This technique can greatly avoid unnecessary uterectomy and, thus, preserve the fertility of the female patients. (authors)

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

    2006-01-01

    Uterine artery embolization (UAE) is a safe and effective method for uterine leiomyomas but its long and middle term effects are definite. Furthermore it bears some exquisite comparison with the conventional therapy but not as a radical one, with a tendency. However, to develop new leiomyomas and recurrence after UAE, there for all patients should be monitored with clinical and imaging examinations for more than 2 years after the procedure. At present, a few literatures involving the factors that could influence the effects of UAE have been issued. It is necessary to carry on large-scale clinical research of the related factors influencing the results of UAE in order to guide clinical practice correctly and swiftly. (authors)

    The purpose of this retrospective study is to assess the radiological and clinical outcome of transcatheter embolization of acquired uterine vascular malformations in patients presenting with secondary postpartum or postabortion vaginal hemorrhage. In a cohort of 17 patients (mean age: 29.7 years; standard deviation: 4.23; range: 25-38 years) 18 embolization procedures were performed. Angiography demonstrated a uterine parenchymal hyperemia with normal drainage into the large pelvic veins (''low-flow uterine vascular malformation'') in 83% (n=15) or a direct arteriovenous fistula (''high-flow uterine vascular malformation'') in 17% (n=3). Clinically, in all patients the bleeding stopped after embolization but in 1 patient early recurrence of hemorrhage occurred and was treated by hysterectomy. Pathological analysis revealed a choriocarcinoma. During follow-up (mean time period: 18.8 months; range: 1-36 months) 6 patients became pregnant and delivered a healthy child. Transcatheter embolization of the uterine arteries, using microparticles, is safe and highly effective in the treatment of a bleeding acquired uterine vascular malformation. In case of clinical failure, an underlying neoplastic disease should be considered. Future pregnancy is still possible after embolization. (orig.)

    The gene for the [alpha]1(III) chain of type III collagen, COL3A1, has been previously mapped to human chromosome 2q24.3-q31 by in situ hybridization. Physical mapping by pulsed-field gel electrophoresis has demonstrated that COL3A1 lies within 35 kb of COL5A2. The authors genotyped the CEPH families at the COL3A2 locus using a pentanucleotide repeat polymorphism within intron 25. They demonstrated significant linkage to 18 anonymous markers as well as the gene for carbamyl phosphate synthetase (CPSI), which had been previously mapped to this region. No recombination was seen between COL3A1 and COL5A2 (Z = 9.93 at [theta] = 0) or D2S24 (Z = 10.55 at [theta] = 0). The locus order is (D2S32-D2S138-D2S148)-(D2S24-COL5A2-COL3A1)-(D2S118-D2S161), with odds of 1:2300 for the next most likely order. These relationships are consistent with the physical mapping of COL3A1 to the distal portion of 2q and place it proximal to CPSI by means of multipoint analysis. These linkage relationships should prove useful in further studies of Ehlers-Danlos syndrome type IV and carbamyl phosphate synthetase I deficiency and provide an additional framework for localizing other genes in this region. 13 refs., 2 figs., 1 tab.

    2016-05-01

    Approximately 30% of women will experience abnormal uterine bleeding (AUB) during their life time. Previous terms defining AUB have been confusing and imprecisely applied. As a consequence, both clinical management and research on this common problem have been negatively impacted. In 2011, the International Federation of Gynecology and Obstetrics (FIGO) Menstrual Disorders Group (FMDG) published PALM-COEIN, a new classification system for abnormal bleeding in the reproductive years. Terms such as menorrhagia, menometrorrhagia, metrorrhagia, dysfunctional uterine bleeding, polymenorrhea, oligomenorrhea, and uterine hemorrhage are no longer recommended. The PALM-COEIN system was developed to standardize nomenclature to describe the etiology and severity of AUB. A brief description of the PALM-COEIN nomenclature is presented as well as treatment options for each etiology. Clinicians will frequently encounter women with AUB and should report findings utilizing the PALM-COEIN system. © 2016 by the American College of Nurse-Midwives.

    The COL4A1 gene encodes the α1-chain of type IV collagen, which is ubiquitously expressed in basement membranes. Mutations in COL4A1 have been reported in autosomal-dominant porencephaly and in patients with symptomatic small vessel brain disease, inconstantly associated with eye defects. We have previously reported three COL4A1 mutations associated with a systemic phenotype that we called HANAC (Hereditary Angiopathy, Nephropathy, Aneurysms, and Cramps). We carried out a clinical and genetic study of three families presenting with characteristic features of HANAC syndrome. Common systemic signs included arterial retinal tortuosity and muscle cramps, with a variable combination of small vessel brain disease, Raynaud phenomena, and kidney defects. Three novel COL4A1 missense substitutions are described, which affect highly conserved glycine residues within the collagenous domain of the protein. All six known mutations associated with the HANAC phenotype are localized within the CB3[IV] fragment of COL4A1, which encompasses major integrin-binding sites. Our results confirm that HANAC syndrome is a distinct clinical entity within the COL4A1-related disorders, which is characterized by systemic involvement and usually asymptomatic brain disease. The restricted distribution of COL4A1 mutations within the CB3[IV] region is a characteristic of the reports of patients with HANAC, which suggests that abnormal cell-type IV collagen interactions may underlie the systemic defects observed in this syndrome.

    Type I collagen is the predominant protein of connective tissues such as skin and bone. Mutations in the type I collagen genes (COL1A1 and COL1A2) mainly cause osteogenesis imperfecta (OI). We describe a patient with clinical signs of Ehlers-Danlos syndrome (EDS), including fragile skin, easy bruising, recurrent luxations, and fractures resembling mild OI. Biochemical collagen analysis of the patients' dermal fibroblasts showed faint overmodification of the type I collagen bands, a finding specific for structural defects in type I collagen. Bidirectional Sanger sequencing detected an in-frame deletion in exon 44 of COL1A1 (c.3150_3158del), resulting in the deletion of three amino acids (p.Ala1053_Gly1055del) in the collagen triple helix. This COL1A1 mutation was hitherto identified in four probands with lethal OI, and never in EDS patients. As the peaks on the electropherogram corresponding to the mutant allele were decreased in intensity, we performed next generation sequencing of COL1A1 to study mosaicism in skin and blood. While approximately 9% of the reads originating from fibroblast gDNA harbored the COL1A1 deletion, the deletion was not detected in gDNA from blood. Most likely, the mild clinical symptoms observed in our patient can be explained by the mosaic state of the mutation. © 2017 Wiley Periodicals, Inc.

    2015-07-17

    The effects of a malfunctional column on the performance of a simulated moving bed (SMB) process were studied experimentally and theoretically. The experimental results of conventional four-zone SMB (2-2-2-2 configuration) and FeedCol operation (2-2-2-2 configuration with one feed column) with one malfunctional column were compared with simulation results of the corresponding SMB processes with a normal column configuration. The malfunctional column in SMB processes significantly deteriorated raffinate purity. However, the extract purity was equivalent or slightly improved compared with the corresponding normal SMB operation because the complete separation zone of the malfunctional column moved to a lower flow rate range in zones II and III. With the malfunctional column configuration, FeedCol operation gave better experimental performance (up to 7%) than conventional SMB operation because controlling product purity with FeedCol operation was more flexible through the use of two additional operating variables, injection time and injection length. Thus, compared with conventional SMB separation, extract with equivalent or slightly better purity could be produced from FeedCol operation even with a malfunctional column, while minimizing the decrease in raffinate purity (less than 2%).

    This report is concerned with multiple primary cancers developing in invasive uterine cancer. Second primary tumors were recorded 27 women with a total of 30 non-uterine cancer (exception of radiation-induced cancer). 17 patients of radiation-induced neoplasm were observed (Rectal cancer 4, soft part sarcoma 4, cancer of urinary bladder 3, bone tumor 3, uterin cancer 2 and cancer of Vulva 1). One case is 4 legions (corpus, sigma, thymoma and stomach), 2 cases are 3 lesions (uterine cervix, stomach and maxillay siuis: uterine cervix, thyroidal gland and radiation-induced soft part sarcoma). Only 5 of these 17 patients were known irradiated dose (50 Gy--55 Gy), however others unknown. The mean latent periods of 17 cases of radiation induced neoplasms are 19.4 years. 16 patients of late second cancers of the cervix appearing from 11 to 36 years (average 19.5 years) after initial radiotherapy were recorded.

    Uterine myoma is the most common benign uterine neoplasm, and associated with numerous gynecologic and obsteric complication. Preoperative acurrate analysis of the number, location and type of the myoma is important, especially in reproductive women. We analyze the MR findings of uterine myoma for evaluation of the role of MR in diagnosis of uterine myoma. We analyze MR findings of 76 myomas in 40 patients, and 34 myomas in 17 patients of them were confirmed by surgery. With 2.0T Spectro-20000(Gold-star, Korea), T1WI axial images and T2WI axial and sagittal images were obtained. Locations were classified into fundus, anterior body, posterior body, right body, left body, and cervix. Types were classified into submucosal, intramural, and subserosal. Associated findings were analyzed also. The most common location and type were posterior body and intramural type, respectively. Ten myomas were confirmed on surgery only, and the causes were as follows: first, all 10 myomas were less than 2 cm in size; second, 1 subserosal myoma was abutted to a large ovarian mass; third, small myomas were abutted to each other, or small one was adjacent to larger one and considered as one large myoma. Degenerative change was noted in 50% of histologically confirmed cases. High signal halo on T2WI was noted in 14%. MR is excellent in detection and localization of uterine leiomyoma larger than 2cm, and may be a preoperative diagnostic method of choice in patient who need myomectomy for preservation of childbearing function.

    Stickler syndrome (STL) is an autosomal, dominantly inherited, clinically variable and genetically heterogeneous connective tissue disorder characterized by ocular, auditory, orofacial and skeletal abnormalities. We conducted targeted resequencing using a next-generation sequencer for molecular diagnosis of a 2-year-old girl who was clinically suspected of having STL with Pierre Robin sequence. We detected a novel heterozygous missense mutation, NM_001854.3:n.4838G>A [NM_001854.3 (COL11A1_v001):c.4520G>A], in COL11A1, resulting in a Gly to Asp substitution at position 1507 [NM_001854.3(COL11A1_i001)] within one of the collagen-like domains of the triple helical region. The same mutation was detected in her 4-year-old brother with cleft palate and high-frequency sensorineural hearing loss.

    EuroCirCol is a conceptual design study for a post-LHC research infrastructure based on an energy-frontier 100 TeV circular hadron collider. ​The award of the 2013 Nobel Prize for Physics acknowledged the leading role of Europe in particle physics, which has a global community of over 10'000 scientists. To reinforce its pole position throughout the 21st century, Europe must be ready to propose an ambitious post-LHC accelerator project by 2018/19. This is one of the main recommendations of the updated European Strategy for Particle Physics, adopted by the CERN Council in May 2013. The EuroCirCol conceptual design study is a direct response to this recommendation, carried out through a collaboration of institutes and universities worldwide. A new research infrastructure of such scale depends on the feasibility of key technologies pushed beyond current state of the art. Innovative designs for accelerator magnets to achieve high-quality fields up to 16 T and for a cryogenic beam vacuum system to cope with unpre...

    Objectives: To evaluate the efficacy of superselective uterine artery embolization for treatment and prevention of obstetric hemorrhage. Methods: Between April 2004 and December 2007, 47 consecutive patients underwent uterine artery embolization to control or prevent hemorrhage, including 20 patients for preventing hemorrhage before abortion and 27 for controlling obstetric hemorrhage. Results: Bilateral uterine artery embolization was performed in all cases except one for abnormal vascular anatomy receiving unilateral approach. Within 10 days after embolization, curettage abortion or uterine-incision delivery was done without hysterectomy, and hemorrhage during abortion was less with average of 54 ml. Conclusions: The high success rate, effectiveness and possibility of preserving reproductive function have made uterine artery embolization the technique of choice to control obstetric hemorrhage, and prophylactic embolization, can prevent hemorrhage before abortion.

    Ehlers-Danlos syndrome classical type is a connective tissue disorder characterized by skin hyperextensibility, atrophic scarring, and joint hypermobility. The condition typically results from mutations in COL5A1 or COL5A2 leading to the functional haploinsufficiency. Here, we report of a 24-year-old male with mild intellectual disability, dysmorphic features, and a phenotype consistent with Ehlers-Danlos syndrome classical type. A copy number variant-calling algorithm from panel sequencing data identified the deletions exons 2-11 and duplications of exons 12-67 within COL5A1. Array comparative genomic hybridization confirmed a 94 kb deletion at 9q34.3 involving exons 2-11 of COL5A1, and a 3.4 Mb duplication at 9q34.3 involving exons 12-67 of COL5A1. © 2018 Japanese Teratology Society.

    The overall aim of this study was to describe uterine bacterial flora during the postpartum period in Danish Holstein cows using the Terminal Restriction Fragment Length Polymorphism (T-RFLP) method. This method produces a pattern of nucleic acid fragments from the microorganisms present, reflecting the "fingerprint" of the actual microbial flora. As well as characterizing changes in flora with time from calving and between herds, data were examined for strong relations between uterine bacterial flora, calving management and uterine condition. In total 125 Holstein cows from five herds were included, and for each cow calving management was recorded. Cows were clinically examined on average 8 (range 0-19) and 28 (range 22-38) days after calving, and a uterine sample was taken for bacterial identification using T-RFLP. Milk samples were taken weekly for progesterone analysis. Bacteria were found in all cows at both examinations, and the flora was composed of many species, including species not traditionally reported to be present in the bovine uterus. The bacterial composition differed according to days from calving and herd. In all five herds Fusobacterium necrophorum, Pseudomonas/Acinetobacter and Bacteroides/Sphingobacterium/Prevotellaceae were among the most common at both examinations. In four herds there was a percentage decrease of F. necrophorum from first to second examination, and in all herds there was a percentage increase of Pseudomonas/Acinetobacter from first to second examination. No differences in bacterial flora were found between cows with different uterine scores, which were influenced by herd, calving difficulty and retained placenta. Copyright © 2013 Elsevier B.V.

    Non-invasive recording of uterine myoelectric activity (electrohysterogram, EHG) could provide an alternative to monitoring uterine dynamics by systems based on tocodynamometers (TOCO). Laplacian recording of bioelectric signals has been shown to give better spatial resolution and less interference than mono- and bipolar surface recordings. The aim of this work was to study the signal quality obtained from monopolar, bipolar and Laplacian techniques in EHG recordings, as well as to assess their ability to detect uterine contractions. Twenty-two recording sessions were carried out on singleton pregnant women during the active phase of labour. In each session the following simultaneous recordings were obtained: internal uterine pressure (IUP), external tension of abdominal wall (TOCO) and EHG signals (5 monopolar and 4 bipolar recordings, 1 discrete approximation to the Laplacian of the potential and 2 estimates of the Laplacian from two active annular electrodes). The results obtained show that EHG is able to detect a higher number of uterine contractions than TOCO. Laplacian recordings give improved signal quality over monopolar and bipolar techniques, reduce maternal cardiac interference and improve the signal-to-noise ratio. The optimal position for recording EHG was found to be the uterine median axis and the lower centre-right umbilical zone. Copyright © 2013 IPEM. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Carcinosarcoma of the uterus is a rare gynaecological neoplasm, which is also known as malignant mixed mesodermal tumor. Traditionally this tumour has been regarded as a subtype of uterine sarcoma, and its origin remains controversial. The exact nature and prognosis was not clear in the past. It is believed that uterine carcinosarcoma have a Mullerian duct origin and have a capacity to differentiate into various mesenchymal and epithelial components. Regarding the histogensis, various theories have been given; of which ′conversion theory′ was broadly accepted. Carcinosarcoma are mostly of monoclonal origin with the carcinomatous component being the driving force. This type of tumor is broadly divided into two groups, homologous and heterologous, depending on the characteristics of the stroma or mesenchymal components of endometrial tissue. It is more frequent in black women and postmenopausal women. Radiation is a possible etiological factor but the exact etiology is not known yet. However, tamoxifen may induce carcinogenesis in some patients. Its clinical feature is very similar to endometrial carcinoma i.e. postmenopausal vaginal bleeding, have a very aggressive behavior and a poor prognosis. This pelvic malignancy is treated by multimodality therapy including surgery, chemotherapy and radiotherapy. Here we are reviewing old concepts about the disease and modern understandings of the origin, classification, pathogenesis and recent advances in the treatment of the uterine carcinosarcoma.

  1. Abnormal uterine bleeding in perimenopause.

    Abnormal uterine bleeding is one of the commonest presenting complaints encountered in a gynecologist's office or primary-care setting. The wider availability of diagnostic tools has allowed prompt diagnosis and treatment of an increasing number of menstrual disorders in an office setting. This White Paper reviews the advantages and disadvantages of transvaginal ultrasound, blind endometrial sampling and diagnostic hysteroscopy. Once a proper diagnosis has been established, appropriate therapy may be embarked upon. Fortunately, only a minority of such patients will have premalignant or malignant disease. When bleeding is sufficient to cause severe anemia or even hypovolemia, prompt intervention is called for. In most of the cases, however, the abnormal uterine bleeding will be disquieting to the patient and significantly affect her 'quality of life'. Sometimes, reassurance and expectant management will be sufficient in such patients. Overall, however, in cases of benign disease, some intervention will be required. The use of oral contraceptive pills especially those with a short hormone-free interval, the insertion of the levonorgestrel intrauterine system, the incorporation of newer medical therapies including antifibrinolytic drugs and selective progesterone receptor modulators and minimally invasive treatments have made outpatient therapy increasingly effective. For others, operative hysteroscopy and endometrial ablation are proven therapeutic tools to provide both long- and short-term relief of abnormal uterine bleeding, thus avoiding, or deferring, hysterectomy.

    Uterine sarcoma is a tumor accounting for only 1% of female genital tract malignancies and between 3% and 7% of uterine tumors. Although a high percentage of patients are diagnosed in the early stages, the survival rates are low. The patients usually present with abnormal vaginal bleeding, abdominal discomfort and pelvic masses. Uterine sarcomas are rapidly progressive tumors. Regional recurrence and distant metastasis are high. About 34-64% patients were reported with relapses. The majority...

  3. Reconstruction of the historical inputs of radionuclides and metal contaminants in the fluvial part of the Seine estuary through the analysis of their sedimentary records

    The Seine estuary is the outlet of a highly anthropogenized catchment area. Marginal areas of the river have trapped fine-grained sediment particles which a number of contaminants are bound to; they give access to the sedimentary records of the past decades. Corings were carried out in three areas: the Seine River, the upper Seine estuary, and at the river mouth. After dating, these cores have led to reconstruct the history of the inputs particulate elements in each of these areas. The comparison of the time series of elemental concentrations between (i) suspended matter during the last decades and (ii) dated sediments along the cores shows that the latter are representative of the former. Particulate fluxes of 55 stable elements and 18 radionuclides were estimated, from 1960 to 2002. Comparison of data acquired in the Seine River and in the upper estuary led to distinguish and quantify the intra-estuarine sources of contaminants that are dominated by phosphogypsum discharges during the 1970's in the Rouen harbour area (upper estuary). The intensity of tidal pumping up to the upper estuary was quantified using transuranics activity ratios. Based on the atmospheric 137 Cs activities over the last decades and core derived 137 Cs activities, a transfer model from the watershed to the river, based on a solid wash-off transfer function by runoff and erosion, is then proposed.

    Full Text Available It has recently been discovered that Collagen III, the encoded protein of the type IV Ehlers-Danlos Syndrome (EDS gene, is one of the major constituents of the pial basement membrane (BM and serves as the ligand for GPR56. Mutations in GPR56 cause a severe human brain malformation called bilateral frontoparietal polymicrogyria, in which neurons transmigrate through the BM causing severe mental retardation and frequent seizures. To further characterize the brain phenotype of Col3a1 knockout mice, we performed a detailed histological analysis. We observed a cobblestone-like cortical malformation, with BM breakdown and marginal zone heterotopias in Col3a1⁻/⁻ mouse brains. Surprisingly, the pial BM appeared intact at early stages of development but starting as early as embryonic day (E 11.5, prominent BM defects were observed and accompanied by neuronal overmigration. Although collagen III is expressed in meningeal fibroblasts (MFs, Col3a1⁻/⁻ MFs present no obvious defects. Furthermore, the expression and posttranslational modification of α-dystroglycan was undisturbed in Col3a1⁻/⁻ mice. Based on the previous finding that mutations in COL3A1 cause type IV EDS, our study indicates a possible common pathological pathway linking connective tissue diseases and brain malformations.

    Episodes of acute abnormal uterine bleeding related to uterine fibroids can cause significant morbidity. Traditional management with high-dose hormonal regimens may not be as effective when used in women with fibroids. A 32-year-old woman with a 12 cm uterine fibroid presented with an episode of acute abnormal uterine bleeding requiring blood transfusion. In lieu of using a hormonal maintenance regimen after the bleeding had stabilized, the patient was treated with ulipristal acetate 5 mg daily for three months. Amenorrhea was induced rapidly and the patient had no further episodes of acute excessive uterine bleeding. She subsequently underwent a laparoscopic myomectomy with a satisfactory outcome. Ulipristal acetate has been shown to induce amenorrhea rapidly in women with uterine fibroids, and it can be a useful treatment in the emergency management of fibroid-related acute abnormal uterine bleeding.

    Full Text Available Uterine sarcoma is a very aggressive and highly lethal disease. Even after a comprehensive staging surgery or en block cytoreduction surgery followed by multimodality therapy (often chemotherapy and/or radiation therapy, many patients relapse or present with distant metastases, and finally die of diseases. The worst outcome of uterine sarcomas is partly because of their rarity, unknown etiology, and highly divergent genetic aberration. Uterine sarcomas are often classified into four distinct subtypes, including uterine leiomyosarcoma, low-grade uterine endometrial stromal sarcoma, high-grade uterine endometrial stromal sarcoma, and undifferentiated uterine sarcoma. Currently, evidence from tumor biology found that these tumors showed alternation and/or mutation of genomes and the intracellular signal pathway. In addition, some preclinical studies showed promising results for targeting receptor tyrosine kinase signaling, phosphatidylinositol 3-kinase/AKT/mammalian target of rapamycin pathway, various kinds of growth factor pathways, Wnt/beta-catenin signaling pathway, transforming growth factor β/bone morphogenetic protein signal pathway, aurora kinase A, MDM2 proto-oncogene, histone deacetylases, sex hormone receptors, certain types of oncoproteins, and/or loss of tumor suppressor genes. The current review is attempted to summarize the recurrent advance of targeted therapy for uterine sarcomas.

    Fisheries observer data recorded between 2003 and 2015 on-board purse seine and longline vessels operating in the Western and Central Pacific Ocean reported more than 10 000 pollution incidents within the exclusive economic zones (EEZs) of 25 Pacific countries and territories, and in international waters. A majority of the reported purse seine pollution incidents related to dumping of plastics waste. Other common pollution incidents related to oil spillages and to abandoned, lost or dumped fishing gear. Data analysis highlighted the need for increased monitoring, reporting, and enforcement of pollution violations by all types of fishing vessels operating in the Pacific region; a regional outreach and compliance assistance programme on marine pollution prevention and improvements in Pacific port waste reception facilities.

    Full Text Available Background: Preterm premature rupture of membranes (PPROM occurs in 17% of pregnancies, which leads to 20% of perinatal death. According to previous studies uterine anomalies are one of the risk factors for preterm birth, PPROM and pregnancies complications. The aim of this study was to evaluate the relationship between PPROM and rupture of membrane (ROM with uterine cavity anomalies based on hysteroscopic findings. Methods: This cross-sectional study was conducted in Imam Khomeini Hospital, Ahvaz, Iran, from May 2011 to May 2012. After conducting a pilot study, 66 nulliparous pregnant women at 14-37 weeks of pregnancy with PPROM and ROM were selected randomly. Then the women were evaluated by hysteroscopy at least six weeks after delivery or miscarriage. The control group includes 66 women with at least one normal pregnancy (without history of PPROM, secondary infertility or recurrent abortion, who underwent diagnostic or therapeutic hysteroscopy for other reasons than PPROM. The hysteroscope instrument specifications were KARL STORZ model (KARL STORZ GmbH & Co. KG, Tuttlingen, Germany, inner sheet 26153 BI, outer sheet 26153 BO, and BA lens with 30 degree. Normal saline solution (Sodium Chloride 0.9% also was applied as distention medium. The study was approved by Ethic Committee of Ahvaz Jundihspur University of Medical Sciences. Informed consent was obtained for all participants. Results: Overall, the frequency of uterine anomalies in case and control groups was 12.12% and 3%, respectively (P<0.05 based on Chi-square test. Possibility of uterine cavity anomalies in the women with preterm premature rupture of membranes (PPROM was significantly higher than the women with normal pregnancy (OR=4.41, CI 95%: 0.9-21/63. About 3% of patients in the case group had undefined uterine anomalies. This anomaly was not in mentioned uterine anomalies classification of American fertility association.

    Full Text Available We present a rare case with gossypiboma following cesarean section which led to uterine wound dehiscence. A 30-year-old woman had been submitted to an emergency cesarean section 4 months previously at another hospital. Clinical and ultrasound findings revealed a large intra-abdominal mass and diffuse peritonitis. At laparotomy, a gossypiboma causing an abscess and uterine wound dehiscence with necrosis of the margins was detected. We performed repetitive wound debridements under broad-spectrum antibiotic cover and eventually resutured the incision. Although hysterectomy has so far been the choice of treatment in the literature once a uterine wound dehiscence had occurred, it was possible in this case to preserve the uterus.

    In the recent decades, laparoscopy has replaced open abdominal procedures in the setting of gynecologic surgery. Extraction of large specimens (e.g., large uteri or myomas) following operative laparoscopy is technically challenging. Technological attempts allow the removal of large and solid pelvic masses via small abdominal incisions (using instruments called morcellators), thus reducing unnecessary laparotomies and improving short-term patients' outcomes. However, morcellation of undiagnosed uterine malignancies may lead to worse survival outcomes. Therefore, the Food and Drug Administration (FDA) warns about the use of power morcellators, thus causing ongoing concerns on the applicability of minimally invasive approaches for myomectomy and the removal of large uteri. In the present review, we sought to assess pro and cons regarding minimally invasive morcellation. This review will discuss the effects of morcellation of undiagnosed uterine malignancies, focusing on possible techniques for preoperative detection of uterine sarcoma and for avoiding intra-abdominal dissemination of potentially malignant tissues. Further efforts are necessary in order to identify tools to make a more accurate and reliable preoperative diagnosis of uterine masses. However, on the light of the current evidence, intra-abdominal morcellation should be banned from clinical practice. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    A technique for transcervical cannulation of the uterus of the bitch for the collection of samples for cytology and microbiology was developed. This technique involved passing a cannula into the uterus with the aid of an endoscope. The uterus was cannulated successfully in mature bitches (over 10 kg) 110 times in 144 attempts. Success of cannulation was influenced by the experience of the operator and ease of cannulation by the stage of the reproductive cycle, the size of the bitch and the type of cannula. Complications associated with the procedure were endometritis, vaginitis and vaginal tears. Uterine cannulation was generally possible in all bitches studied at all stages of the reproductive cycle. Techniques for the collection of samples from the uterus for cytology and microbiology and for the processing of samples for uterine cytology are outlined. Hysteroscopy was performed on seven occasions in post partum bitches and was found to be possible at least until day 17 after whelping.

    Some epidemiological studies have found that uterine leiomyoma can increase the risk of placenta abruption. To date, the meta-analysis has not been performed for assessing the relationship between uterine leiomyoma and placenta abruption. This meta-analysis was conducted to estimate the association between uterine leiomyoma and the risk of placenta abruption. A literature search was conducted out in major databases PubMed, Web of Science, and Scopus from the earliest possible year to October 2016. The heterogeneity across studies was explored by Q-test and I 2 statistic. The publication bias was assessed by Begg's and Egger's tests. The results were showed using odds ratio (OR) estimate with its 95% confidence intervals (CI) using a random-effects model. The literature search included 953 articles until October 2016 with 232,024 participants. Based on OR estimates obtained from case-control and cohort studies, there was significant association between uterine leiomyoma and placenta abruption (2.63; 95% CI: 1.38, 3.88). We showed based on reports in observational studies that uterine leiomyoma is a risk factor for placenta abruption.

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

    Full Text Available Cornual pregnancy is a diagnostic and therapeutic challenge with potential severe consequences if uterine rupture occurs with following massive intraabdominal bleeding. We report a case of a misdiagnosed ruptured cornual pregnancy occurring at 21 weeks of gestation. Ultrasound examination and computer tomography revealed no sign of abnormal pregnancy. The correct diagnosis was first made at emergency laparotomy. Uterine rupture should be considered in pregnant women presenting with abdominal pain and haemodynamic instability.

    Full Text Available INTRODUÇÃO: A doença cística das vias biliares é anomalia congênita que pode acometer as vias biliares intra e/ou extra-hepáticas. A extra-hepática inclui os cistos de colédoco e a intra-hepática é conhecida por Doença de Caroli. Os cistos de colédoco de tamanho gigante são muito raros. OBJETIVO: Relatar o caso de um cisto de colédoco de tamanho gigante em uma paciente feminina. RELATO DE CASO: Mulher de 19 anos foi admitida com história de icterícia e acolia fecal há sete dias. Referia dor epigástrica associada com ingestão de dieta rica em gordura. Nos antecedentes pessoais relatou dois episódios de icterícia, aos 8 e 14 anos, que progrediram espontaneamente. No exame físico apresentava icterícia (+3/+4 e uma massa palpável indolor em mesogástrio foram os únicos achados. A ultrassonografia demonstrou grande formação cística de paredes finas adjacente ao hepatocolédoco, pâncreas e rim direito que media 18,5 x 10,2 cm. A colangioressonância confirmou o grande cisto de colédoco e hepatojejunoanastomose em "Y" de Roux após excisão do cisto e colecistectomia foi realizada. A formação cística media 20 x 15,5 x 12,5 cm e com um volume médio de 1000 mL. A paciente encontra-se em acompanhamento ambulatorial sem alterações hepatobiliares após o sétimo mês da operação. CONCLUSÃO: O cisto de colédoco deve fazer parte do diagnóstico diferencial em pacientes adultos jovens com icterícia e massa palpável; no entanto, a diferenciação entre ele e neoplasia maligna deve ser pesquisada.BACKGROUND: Choledochal cyst represents a rare congenital anomaly, eventually associated with intra and extrahepatic biliary tract disorders.

    The authors have recently reported that the anti-androgen hydroxyflutamide causes delayed implantation and exhibits antideciduogenic activity in the rat. The present experiments were conducted to examine whether hydroxyflutamide binds to the uterine progesterone receptors and/or alters the progesterone binding sites in the uterus. Cytosol and nuclear fractions from decidualized rat uterus were incubated with [3H]-R5020 without or with increasing concentrations of radioinert R5020, RU486, dihydrotestosterone, or hydroxyflutamide. From the log-dose inhibition curves, the relative binding affinity of both hydroxyflutamide and dihydrotestosterone was less than 0.1% and 2%, compared with R5020 (100%) for displacing [3H]-R5020 bound to uterine cytosol and nuclear fractions, respectively. Injection of estradiol-17 beta (1 microgram/rat) to ovariectomized prepubertal rats induced a 1.85-fold increase in uterine weight by 24 h. Hydroxyflutamide at 2.5 or 5.0 mg did not significantly alter the estrogen-induced increase in uterine weight. Compared to vehicle alone, estrogen induced an approximately 5-fold increase in uterine cytosolic progesterone binding sites. Hydroxyflutamide at both 2.5- and 5.0-mg doses significantly attenuated the estrogen-induced elevation in uterine progesterone binding sites. These studies demonstrate that hydroxyflutamide does not bind with high affinity to progesterone receptors, but suppresses the estrogen-induced elevation in progesterone receptor levels in the uterus

    To determine the frequency and to analyze the predisposing factors, maternal and fetal outcome of uterine rupture. All cases of ruptured uterus, who were either admitted with or who developed this complication in the hospital, were included in the study. Demographic data, details regarding the most probable predisposing factor, type of rupture, the management and maternal and fetal outcome were taken into consideration for analysis.During three years, total number of deliveries was 18668, and there were 103 cases of uterine rupture (0.55%).Out of these, only 13 (12.62%) patients were booked. Most of the patients presented between the ages of 26-30 years (42.71%). Majority of ruptures occurred in para 2-4 (44.66%). Fifty five cases (53.39%) had a previous caesarean section scar. In 68 (66.01%) cases, the tear was located in lower uterine segment. In 93 (90.29%) cases, anterior uterine wall was involved. Rupture was complete in 79 (76.69%)cases. Repair of uterus was done in 79 (76.69%) cases. Hysterectomy was performed in 24 (23.30%) cases. There were 8 (7.76% or 77.66/1000) maternal deaths and 85 (81.73% or 825 / 1000) perinatal deaths.This study confirms high frequency of such serious preventable obstetrical problem which can lead to high fetomaternal mortality. Rupture of caesarean section scar was the most common cause of uterine rupture found in this series. (author)

    Li Wei

    Full Text Available OBJECTIVE: To develop an orthotopic, allogeneic, uterine transplantation technique and an effective immunosuppressive protocol in the sheep model. METHODS: In this pilot study, 10 sexually mature ewes were subjected to laparotomy and total abdominal hysterectomy with oophorectomy to procure uterus allografts. The cold ischemic time was 60 min. End-to-end vascular anastomosis was performed using continuous, non-interlocking sutures. Complete tissue reperfusion was achieved in all animals within 30 s after the vascular re-anastomosis, without any evidence of arterial or venous thrombosis. The immunosuppressive protocol consisted of tacrolimus, mycophenolate mofetil and methylprednisolone tablets. Graft viability was assessed by transrectal ultrasonography and second-look laparotomy at 2 and 4 weeks, respectively. RESULTS: Viable uterine tissue and vascular patency were observed on transrectal ultrasonography and second-look laparotomy. Histological analysis of the graft tissue (performed in one ewe revealed normal tissue architecture with a very subtle inflammatory reaction but no edema or stasis. CONCLUSION: We have developed a modified procedure that allowed us to successfully perform orthotopic, allogeneic, uterine transplantation in sheep, whose uterine and vascular anatomy (apart from the bicornuate uterus is similar to the human anatomy, making the ovine model excellent for human uterine transplant research.

    2012-06-01

    We describe a method for modelling the relative effects of seine net biases and for deriving equivalence factors to standardize fish abundance data sets collected using multiple sampling gears. Nearshore fish communities were sampled from 10 sites in each of the basin and riverine portions of the Swan-Canning Estuary, Western Australia, using beach seine nets of three different lengths (21.5, 41.5 and 133 m). The resulting data were subjected to generalized linear modelling to derive equivalence factors relating catches from the two larger net types to those from the 21.5 m net. Equivalence factors were derived on the basis of functional habitat guilds of fish (small benthic, small pelagic, demersal, pelagic). Prior to standardization, catches from the 41.5 and 133 m nets consistently underestimated fish densities relative to those from the 21.5 m net. Following standardization, the degree to which fish densities were underestimated by the two larger nets was reduced and/or eliminated for most guilds, and particularly in the case of the 133 m net. For both of the larger nets, standardized estimates of total fish density across all species were far closer to those recorded using the 21.5 m seine, thus indicating that standardization of the fish abundance data had greatly reduced the overall effects of the biases introduced by the different net types. This approach could be applied to other systems and sampling methods, to facilitate more robust comparisons of fish abundances between studies with divergent sampling methodologies.

    Over the past 20 years, rules concerning wastewater treatment and quality of water discharged into the environment have changed considerably. Huge investments have been made in Paris conurbation to improve waste water treatment processes in accordance with the European Water Framework Directive. The interdepartmental association for sewage disposal in Paris conurbation (SIAAP) carried out a monitoring of both fish assemblages and water quality in the Seine River around the Paris conurbation (France) since the early 90's. The main goal of this study was to estimate the influence of the water quality improvement on fish. On one hand, the study confirmed the improvement of the water quality (dissolved oxygen, ammonia nitrogen, organic matter) in the Seine River, mostly focused downstream of Paris conurbation. On the other hand, an increase of the number of species occurred from 1990 (14) to 2013 (21). Moreover, changes in the river Seine assemblages happened over that 23-year period with emergence of sensitive species (ruffe, scalpin and pike-perch). The improvement of the water quality was also reported with respect to the Index of Biotic Integrity (IBI). However, no variation of pollutant concentrations in roach, eel and chub muscles has been observed. An exceedance of the environmental quality standards have even been reported all over this period as regards mercury and organochlorine.

    1994-01-01

    Escherichia coli F-18, a normal human fecal isolate, is an excellent colonizer of the streptomycin-treated mouse large intestine. E. coli F-18Col-, a derivative of E. coli F-18 which no longer makes the E. coli F-18 colicin, colonizes the large intestine as well as E. coli F-18 when fed to mice...... alone but is eliminated when fed together with E. coli F-18. Recently we randomly cloned E. coli F-18 DNA into E. coli F-18Col- and let the mouse intestine select the best colonizer. In this way, we isolated a 6.5-kb E. coli F-18 DNA sequence that simultaneously stimulated synthesis of type 1 fimbriae...... and enhanced E. coli F-18Col- colonizing ability. In the present investigation we show that the gene responsible for stimulation of type 1 fimbriae synthesis appears to be leuX, which encodes a tRNA specific for the rare leucine codon UUG. Moreover, it appears that expression of leuX may be regulated by two...

  13. Atypical olfactory groove meningioma associated with uterine fibromatosis; case report

    2016-11-01

    Full Text Available The concomitant presence of the olfactory groove meningioma with uterine fibrosis is very rare. Our report presents the case of a giant olfactory groove meningioma revealed after a uterine fibroma resection in a 44 years-old female, due to a generalized seizure 10 days after operation. Cranial CT-scan identified the tumor as an olfactory groove meningioma. The tumor was operated with a macroscopically complete resection; the endothermal coagulation of the dura attachment was performed (Simpson II with a good postoperative evolution. Laboratory results showed the presence of receptors for steroid hormones both in meningioma and uterine tumor, and the histopathological examination revealed an atypical meningioma with 17% proliferation markers. Our findings suggest that even though meningiomas are benign tumors and a complete resection usually indicates a good prognosis, the association with uterine fibromatosis and the presence of high percentage of steroid receptors creates a higher risk to relapse, imposing therefore a good monitoring.

  14. Wound healing genes and susceptibility to cutaneous leishmaniasis in Brazil: Role of COL1A1

    2015-01-01

    Previous studies have demonstrated a role for wound healing genes in resolution of cutaneous lesions caused by Leishmania spp. in both mice and humans, including the gene FLI1 encoding Friend leukaemia virus integration 1. Reduction of Fli1 expression in mice has been shown to result in up-regulation of collagen type I alpha 1 (Col1a1) and alpha 2 (Col1a2) genes and, conversely, in down-regulation of the matrix metalloproteinase 1 (Mmp1) gene, suggesting that Fli1 suppression is involved in activation of the profibrotic gene program. Here we examined single nucleotide polymorphisms (SNPs) in these genes as risk factors for cutaneous (CL) and mucosal leishmaniasis (ML), and leishmaniasis per se, caused by L. braziliensis in humans. SNPs were genotyped in 168 nuclear families (250 CL; 87 ML cases) and replicated in 157 families (402 CL; 39 ML cases). Family-based association tests (FBAT) showed the strongest association between SNPs rs1061237 (combined P=0.002) and rs2586488 (combined P=0.027) at COL1A1 and CL disease. This contributes to our further understanding of the role of wound healing in the resolution of CL disease, providing potential for therapies modulating COL1A1 via drugs acting on FLI1.

    2012-04-01

    Women who wish to conceive are nowadays more likely to present with uterine fibroids, mainly because of the delay in childbearing in our society. The relationship between uterine fibroids and human reproduction is still controversial and counselling patients might sometimes be challenging. This paper is to assist those involved in the management of patients of reproductive age presenting with uterine fibroids. The interference of fibroids on fertility largely depends on their location. Submucous fibroids interfere with fertility and should be removed in infertile patients, regardless of the size or the presence of symptoms. Intramural fibroids distorting the cavity reduce the chances of conception, while investigations on intramural fibroids not distorting the cavity have so far given controversial results. No evidence supports the systematic removal of subserosal fibroids in asymptomatic, infertile patients. Myomectomy is still the 'gold standard' in fibroid treatment for fertility-wishing patients. In experienced hands, hysteroscopic myomectomy is minimally invasive, safe, and effective. Abdominal and laparoscopic myomectomy might be challenging, but potential risks could be reduced by new strategies and techniques.

    Brain metastasis from uterine cervical cancer is rare, with an incidence of 0.5%, and usually occurs late in the course of the disease. We report a case of uterine cervical cancer with brain metastasis as the initial site of presentation. A 50-year-old woman with headache, vertigo, amnesia and loss of appetite was admitted for persistent vomiting. Contrast enhanced computed tomography showed a solitary right frontal cerebral lesion with ring enhancement and uterine cervical tumor. She was diagnosed with uterine cervical squamous cell carcinoma with parametrium invasion and no other distant affected organs were detected. The cerebral lesion was surgically removed and pathologically proved to be metastasis of uterine cervical squamous cell carcinoma. The patient underwent concurrent chemoradiotherapy, followed by cerebral radiation therapy, but multiple metastases to the liver and lung developed and the patient died 7 months after diagnosis of brain metastasis. © 2015 The Authors.

    The objective of this study was to investigate the effect of time of first postpartum ovulation after calving on uterine involution in dairy cows with and without uterine puerperal disease. Transvaginal follicular puncture (FP) of follicles >6 mm suppressed ovulation and development of a CL until Day 42 after calving. Fifty-three lactating Holstein Friesian cows (3.4 ± 1.2 years old, parity 2.5 ± 1.0 [median ± mean absolute deviation]) were divided into groups on the basis of the presence (UD+) or absence (UD-) of uterine disease and whether FP was carried out (FP+) or not (FP-). Uterine disease was defined as the occurrence of retained fetal membranes and/or metritis. This resulted in the following groups: UD-FP- (n = 15), UD-FP+ (n = 13), UD+FP- (n = 13), and UD+FP+ (n = 12). A general examination, vaginoscopy, transrectal palpation, and transrectal B-mode sonography of the reproductive organs were conducted on Days 8, 11, 18, and 25 and then every 10 days until Day 65 after calving. After hormonal synchronization of ovulation (cloprostenol between Days 55 and 60 postpartum and GnRH 2 days later), cows were inseminated in the next spontaneous estrus. On average, the cows ovulated on Day 21.0 ± 6.0 (UD-FP-), 50.0 ± 4.0 (UD-FP+), 16.0 ± 3.0 (UD+FP-), and 48.0 ± 2.0 (UD+FP+) postpartum. Calving-to-conception interval and first-service conception rates were not affected by FP (P > 0.05). Healthy cows with FP had smaller (P uterine horn and cervical diameters assessed sonographically than cows without FP. FP reduced the prevalence of purulent vaginal discharge and uterine size assessed transrectally in UD+ cows (P uterine involution in cows with and without uterine disease.

  2. Peritoneal dissemination complicating morcellation of uterine mesenchymal neoplasms.

    Directory of Open Access Journals (Sweden)

    Michael A Seidman

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

    To analyze gray-scale US, color and duplex Doppler US, and angiographic findings in patients with acquired uterine arteriovenous malformations (AVMs), and to evaluate the usefulness of these modalities in the diagnosis of this disease and the effect of transcatheter arterial embolization in its treatment. During a recent seven-year period, we diagnosed 21 cases of acquired uterine AVM. Nineteen of these patients had a history of causative D and C (between one and seven D and C procedures per patient), one had a history of causative cesarean section, and one had cervical conization. All patients underwent transabdominal and endovaginal gray-scale, color Doppler, and duplex Doppler US and angiography, with therapeutic embolization of bilateral uterine arteries. The majority underwent follow-up Doppler US after embolization. The gray-scale US morphology of uterine AVMs included subtle myometrial inhomogeneity and multiple distinct, small anechoic spaces in the thickened myometrium or endometrium. Color Doppler US showed a tangle of tortuous vessels with multidirectional, high-velocity arterial flow, which was focally or asymmetrically distributed. Duplex Doppler US depicted a waveform of fast arterial flow with low resistance, while angiography demonstrated a complex tangle of vessels supplied by enlarged uterine arteries, in association with early venous drainage during the arterial phase, and staiss of contrast medium within abnormal vasculature. Where AVMs were combined with a pseudoaneurysm, this finding was observed. Transcatheter arterial embolization provided a complete cure, without recurrence. Color and duplex Doppler US in an appropriate modality for the detection and diagnosis of uterine AVMs and for follow-up after embolization.

Color Doppler US showed a tangle of tortuous vessels with multidirectional, high-velocity arterial flow, which was focally or asymmetrically distributed. Duplex Doppler US depicted a waveform of fast arterial flow with low resistance, while angiography demonstrated a complex tangle of vessels supplied by enlarged uterine arteries, in association with early venous drainage during the arterial phase, and staiss of contrast medium within abnormal vasculature. Where AVMs were combined with a pseudoaneurysm, this finding was observed. Transcatheter arterial embolization provided a complete cure, without recurrence. Color and duplex Doppler US in an appropriate modality for the detection and diagnosis of uterine AVMs and for follow-up after embolization. Transcatheter arterial embolization is a safe and effective method of treating this disease.

    Objective The objective of this study was to evaluate the association between labor dystocia and uterine rupture. Methods We performed a secondary analysis of a multicenter case-control study that included women with single, prior, low-transverse cesarean section who experienced complete uterine rupture during a trial of labor (TOL). For each case, three women who underwent a TOL without uterine rupture were selected as controls. Data were collected on cervical dilatations from admission to delivery. We evaluated the relationship between uterine rupture and labor dystocia according to several criteria, including the World Health Organization's (WHO's) partogram. Results Data were available for 90 cases and 260 controls. Compared with the controls, uterine rupture was associated with less cervical dilatation on admission, slower cervical dilatation in the first stage of labor and longer second stage of labor (all with p dystocia is a significant risk factor for uterine rupture. Labor progression should be assessed regularly in women with prior cesarean. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

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

    Purpose: To compare the rate of reintervention and midterm changes in symptom severity (SS) and Total health-related quality of life (HRQoL) scores after uterine artery embolization (UAE) and magnetic resonance-guided high-intensity focused ultrasound (MR-g HIFU) for symptomatic uterine fibroids. Methods: Eighty women (median age 38.3 years), equally eligible for MR-g HIFU and UAE who underwent one of both treatments between 2002 and 2009 at our institution, were included. The primary end point of the study was defined as the rate of reintervention after both therapies. The secondary outcome was defined as changes in SS and Total HRQoL scores after treatment. SS and Total HRQoL scores before treatment and at midterm follow-up (median 13.3 months) were assessed by the uterine fibroid symptom and quality-of-life questionnaire (UFS-QoL) and compared. Results: The rate of reintervention was significantly lower after UAE than after MR-g HIFU (p = 0.002). After both treatments, SS and Total HRQoL scores improved significantly from baseline to follow-up (UAE: p < 0.001, p < 0.001; MR-g HIFU: p = 0.002, p < 0.001). Total HRQoL scores were significantly higher after UAE than after MR-g HIFU (p = 0.032). Changes in the SS scores did not differ significantly for both treatments (p = 0.061). Conclusion: UAE and MR-g HIFU significantly improved the health-related quality of life of women with symptomatic uterine fibroids. After UAE, the change in Total HRQoL score improvement was significantly better, and a significantly lower rate of reintervention was observed.

    Objective To identify risk factors for uterine atony or hemorrhage. Study Design Secondary analysis of a 3-arm double-blind randomized trial of different dose-regimens of oxytocin to prevent uterine atony after vaginal delivery. The primary outcome was uterine atony or hemorrhage requiring treatment. Twenty-one potential risk factors were evaluated. Logistic regression was used to identify independent risk factors using 2 complementary pre-defined model selection strategies. Results Among 1798 women randomized to 10, 40 or 80U prophylactic oxytocin after vaginal delivery, treated uterine atony occurred in 7%. Hispanic (OR 2.1; 95% CI 1.3–3.4) and non-Hispanic whites (OR 1.6; 95% CI 1.0–2.5), preeclampsia (OR 3.2; 95% CI 2.0–4.9) and chorioamnionitis (OR 2.8; 95% CI 1.6–5.0) were consistent independent risk factors. Other risk factors based on the specified selection strategies were obesity, induction/augmentation of labor, twins, hydramnios, anemia, and arrest of descent. Amnioinfusion appeared to be protective against uterine atony (OR 0.53; 95% CI 0.29–0.98). Conclusion Independent risk factors for uterine atony requiring treatment include Hispanic and non-Hispanic white ethnicity, preeclampsia and chorioamnionitis. PMID:23507549

    Full Text Available Background & aim: Various uterine disorders lead to infertility in women of reproductive ages. This study was performed to describe the common uterine causes of infertility and sonographic evaluation of these causes for midwives. Methods: This literature review was conducted on the manuscripts published at such databases as Elsevier, PubMed, Google Scholar, and SID as well as the original text books between 1985 and 2015. The search was performed using the following keywords: infertility, uterus, ultrasound scan, transvaginal sonography, endometrial polyp, fibroma, leiomyoma, endometrial hyperplasia, intrauterine adhesion, Asherman’s syndrome, uterine synechiae, adenomyosis, congenital uterine anomalies, and congenital uterine malformations. Results: Atotal of approximately 180 publications were retrieved from the respective databases out of which 44 articles were more related to our topic and studied as suitable references. In addition, 11 published books on ultrasonography and infertility were evaluated to provide more precise knowledge on the mentioned areas. According to the literature, ultrasonography has a crucial role in the investigation and differentiation of uterine disorders in females with infertility. However, the diagnosis depends on the day of menstruation, clinical prese-ntations, and the suspected uterine disorder. In this review, we provided the key notes about proper timing of the ultrasound examination. Conclusion: Ultrasonography is the first step imaging tool in the investigation of female infertility, which provides information for the diagnosis of uterine disorders. However, the accurate diagnosis depends on the “time of evaluation”. Therefore, every midwife needs to learn about the “optimum timing” for ultrasound evaluation based on each patient.

    To characterize the efficacy of mifepristone treatment on extracellular matrix (ECM) production in leiomyomas. Laboratory study. University research laboratory. None. Treatment of human immortalized two-dimensional (2D) and three-dimensional (3D) leiomyoma and myometrial cells with mifepristone and the progestin promegestone (R5020). Expression of COL1A1, fibronectin, versican variant V0, and dermatopontin in treated leiomyoma cells by Western blot analysis and confirmatory immunohistochemistry staining of treated 3D cultures. Treatment with progestin stimulated production of COL1A1, fibronectin, versican, and dermatopontin. Mifepristone treatment inhibited protein production of these genes, most notably with versican expression. Combination treatment with both the agonist and antagonist further inhibited protein expression of these genes. Immunohistochemistry performed on 3D cultures demonstrated generalized inhibition of ECM protein concentration. Our study demonstrated that the progesterone agonist R5020 directly stimulated extracellular matrix components COL1A1, fibronectin, versican, and dermatopontin production in human leiomyoma cells. Progesterone antagonist mifepristone decreased protein production of these genes to levels comparable with untreated leiomyoma cells. Published by Elsevier Inc.

    Uterine leiomyomas are extremely common, benign, smooth muscle tumors that represent a significant public health problem. Although there have been few molecular studies of uterine leiomyomas, most of them have reported a very low frequency of loss of heterozygosity (LOH) in different regions...... of the genome. The detection of LOH has been used to identify genomic regions that harbor tumor suppressor genes and to characterize different tumor types. We have used a set of 15 microsatellite polymorphism markers to examine the frequency of allele loss in a panel of 64 human uterine leiomyomas matched...... to normal DNAs. The markers were chosen from regions involved in losses identified by comparative genomic hybridization in a subset of uterine leiomyomas described in a previous report. DNA from tumors and normal tissue was amplified by the polymerase chain reaction and subsequently analyzed using an ABI...

    Full Text Available ColE1 plasmids are important vehicles for the spread of antibiotic resistance in the Enterobacteriaceae and Pasteurellaceae families of bacteria. Their monitoring is essential, as they harbor important resistant determinants in humans, animals and the environment. In this work, we have analyzed ColE1 replicons using bioinformatic and experimental approaches. First, we carried out a computational study examining the structure of different ColE1 plasmids deposited in databases. Bioinformatic analysis of these ColE1 replicons revealed a mosaic genetic structure consisting of a host-adapted conserved region responsible for the housekeeping functions of the plasmid, and a variable region encoding a wide variety of genes, including multiple antibiotic resistance determinants. From this exhaustive computational analysis we developed a new PCR-based technique, targeting a specific sequence in the conserved region, for the screening, capture and sequencing of these small plasmids, either specific for Enterobacteriaceae or specific for Pasteurellaceae. To validate this PCR-based system, we tested various collections of isolates from both bacterial families, finding that ColE1 replicons were not only highly prevalent in antibiotic-resistant isolates, but also present in susceptible bacteria. In Pasteurellaceae, ColE1 plasmids carried almost exclusively antibiotic resistance genes. In Enterobacteriaceae, these plasmids encoded a large range of traits, including not only antibiotic resistance determinants, but also a wide variety of genes, showing the huge genetic plasticity of these small replicons. Finally, we also used a metagenomic approach in order to validate this technique, performing this PCR system using total DNA extractions from fecal samples from poultry, turkeys, pigs and humans. Using Illumina sequencing of the PCR products we identified a great diversity of genes encoded by ColE1 replicons, including different antibiotic resistance

    Purpose. To evaluate the mid-term clinical results and patient satisfaction following uterine artery embolization (UAE) in women with symptomatic fibroids. Methods. Between August 1998 and December 2002, 135 patients had UAE for symptomatic uterine fibroids. All patients were asked to fill in a questionnaire. Questions were aimed at changes in bleeding, pain, and bulk-related symptoms. Symptoms after UAE were scored as disappeared, improved, unchanged or worsened. Adverse events were noted, such as vaginal dryness and discharge, menopausal complaints or fibroid expulsion. Patient satisfaction after UAE was assessed. Patient satisfaction of women embolized with polyvinyl alcohol (PVA) particles was compared with satisfaction of women embolized with calibrated microspheres. Results. The questionnaire was returned by 110 of 135 women (81%) at a median time interval of 14 months following UAE. In 10 women additional embolization or hysterectomy had been performed. Of the 110 responders, 86 (78%) were satisfied with the result of UAE. The proportion of satisfied women was higher in the group embolized with calibrated microspheres than in women embolized with PVA, although this difference was not statistically significant (p = 0.053). Conclusion. UAE in women with symptomatic uterine fibroids leads to improvement of symptoms and patient satisfaction is good in the vast majority after a median follow-up period of 14 months

    Osteogenesis imperfecta (OI) is a family of genetic disorders associated with bone loss and fragility. Mutations associated with OI have been found in genes encoding the type I collagen chains. People with OI type I often produce insufficient α1-chain type I collagen because of frameshift, nonsense, or splice site mutations in COL1A1 or COL1A2. This report is of a Chinese daughter and mother who had both experienced two bone fractures. Because skeletal fragility is predominantly inherited, we focused on identifying mutations in COL1A1 and COL1A2 genes. A novel mutation in COL1A1, c.700delG, was detected by genomic DNA sequencing in the mother and daughter, but not in their relatives. The identification of this mutation led to the conclusion that they were affected by mild OI type I. Open reading frame analysis indicated that this frameshift mutation would truncate α1-chain type I collagen at residue p263 (p.E234KfsX264), while the wild-type protein would contain 1,464 residues. The clinical data were consistent with the patients’ diagnosis of mild OI type I caused by haploinsufficiency of α1-chain type I collagen. Combined with previous reports, identification of the novel mutation COL1A1-c.700delG in these patients suggests that additional genetic and environmental factors may influence the severity of OI.

    Uterine fibroid is a benign tumour of uterine smooth muscle. The purpose of this review is to bring to light the current spectra of presentation and management status of this benign and very important cause of menstrual and fertility disturbance in African women and the Black race in general. This is especially so with the trivialization of its aetological factors and treatment by claims from alternative medical practitioners. This review, therefore sought to document what is currently known about the condition and what could possibly be done to achieve better results in its management. Literature on the subject above was reviewed using manual library search, electronic books such as CD-ROMS and journals articles published by various local and international authors on the subject; it also included internet search on relevant aspects of the topic. Fibroid is the commonest benign tumour of the female genital tract, it contributes about 70 to 80% of new growths in the female genital tracts, it is a cause of significant morbidity in women of reproductive age group and when complicated could be a significant cause of mortality. Spectrum of presentation mainly involves disturbance of menstruation, reduction in fertility, pressure and obstructive symptoms and rarely malignant presentations. When recognized early effective conservative and definitive therapies are available to offer relief for women and to make their menstrual and reproductive life more meaningful. From the literature reviewed, it was obvious that the subject of uterine fibroid is still not fully exhausted and there were a lot of research questions waiting to be answered on the aetiopathogenesis of the disease. There is also the need to fashion out better treatment alternatives that will reduce morbidity in the process of managing the patient as well as those that will further enhance reproductive potentials after treatment.

    Uterine tumor resembling ovarian sex-cord tumor is a very rare uterine neoplasm that was first described by Clement and Scully in 1976. Since then, approximately 70 cases have been reported. However, these case reports have mainly described and discussed the pathologic and clinical features, and few radiologic findings have been presented. We experienced a case of a uterine tumor resembling ovarian sex-cord tumor, which was considered a uterine leiomyoma or leiomyosarcoma upon initial impression at preoperative evaluation including transvaginal ultrasonography and pelvic magnetic resonance imaging. Its diagnosis was pathologically confirmed after total abdominal hysterectomy.

    Collagen XVII expression has recently been demonstrated to be correlated with the tumor malignance. While Collagen XVII is known to be widely distributed in neurons of the human brain, its precise role in pathogenesis of glioblastoma multiforme (GBM) is unknown. In this study, we identified and characterized a new PTEN-COL17A1 fusion gene in GMB using transcriptome sequencing. Although fusion gene did not result in measurable fusion protein production, its presence is accompanied with high levels of COL17A1 expression, revealed a novel regulatory mechanism of Collagen XVII expression by PTEN-COL17A1 gene fusion. Knocked down Collagen XVII expression in glioma cell lines resulted in decreased tumor invasiveness, along with significant reduction of MMP9 expression, while increased Collagen XVII expression promotes invasive activities of glioma cells and associated with GBM recurrences. Together, our results uncovered a new PTEN-COL17A1 fusion gene and its novel regulatory role in Collagen XVII expression and GBM malignance, and demonstrated that COL17A1 could serve as a useful prognostic biomarker and therapeutic targets for GBM.

    We report a case in which an intramural uterine Ieiomyoma was transvaginally expelled after uterine arterial embolization (UAE). A 29-year-old unmarried female presented with vaginal bleeding, and at pre-treatment MRI an intramural leiomyoma was diagnosed. UAE was performed and after 13 days the tumor was transvaginally expelled. Follow-up MRI performed seven days later depicted a large myometrial defect in the anterior uterine wall; subsequent follow-up MRI showed that the defect became gradually smaller, and the size and configuration of the uterus progressively normalized.

    Objective: To evaluate the therapeutic effect of intra-arterial chemotherapy with Ddp and 5-Fu via bilateral uterine arteries for advanced uterine cervical cancer. Methods: During the period of Jan. 2006-Jan. 2009, initial intra-arterial chemotherapy by using a combination of Ddp and 5-Fu via bilateral uterine arteries was performed in 72 patients (mean age 42.9 years) with advanced uterine cervical caner. Of 72 patients, stage I b2 cervical cancer was confirmed in 28, stage II a in 12 and stage II b in 32. Pathologically, cervical squamous cell carcinoma was seen in 56 and cervical adenocarcinoma in 16 patients. Ultrasonography and physical examination were conducted both before and after intra-arterial chemotherapy. The therapeutic results,complications,the surgical resection rate and the pathologic findings were observed and statistically analyzed. Results: Fifty-four patients received one treatment course and 18 patients received two treatment courses. The over all response rate was 77.8%. The response rates of patients with I b2, II a and II b cervical cancer were 92.9%, 83.3% and 62.5% respectively, the difference between three groups was statistically significant (P < 0.05). And the response rates of patients with squamous cell carcinoma and adenocarcinoma were 85.7% and 50.0% respectively, the difference between the two was statistically significant (P < 0.05). The most common side-effects included gastrointestinal symptoms and bone marrow suppression. Thirty-four patients received radical hysterectomy,among them, 22 (78.6%) had stage I b2, 8 (66.7%) had stage II a and 4 (12.5%) had stage II b cervical cancer (P < 0.05). Pathologic exam found no vaginal invasion and ovarian metastasis in all 34 patients. The occurrence of metastasis to lymph nodes and para uterine infiltration were 17.6% and 11.8% respectively. Conclusion: Intra-arterial chemotherapy with a combination of DDP and 5-Fu via bilateral uterine arteries can safely and effectively reduce the

    Immunoperoxidase staining was used to investigate the origin of human alpha-uterine protein (AUP). Specific staining was observed in the glandular epithelium of the endometrium during the secretory phase of the menstrual cycle and during pregnancy, and in a patient on an oestrogen-progestagen contraceptive pill. The pattern of staining strongly suggests that AUP is secreted into the uterine lumen. The location and concentration of AUP in the uterus may explain the relative concentrations of AUP in amniotic fluid and maternal serum.

    To evaluate the safety and clinical efficacy of transcatheter uterine artery embolization (UAE) for post-myomectomy hemorrhage. We identified eight female patients (age ranged from 29 to 51 years and with a median age of 37) in two regional hospitals who suffered from post-myomectomy hemorrhage requiring UAE during the time period from 2004 to 2012. A retrospective review of the patients' clinical data, uterine artery angiographic findings, embolization details, and clinical outcomes was conducted. The pelvic angiography findings were as follows: hypervascular staining without bleeding focus (n = 5); active contrast extravasation from the uterine artery (n = 2); and pseudoaneurysm in the uterus (n = 1). Gelatin sponge particle was used in bilateral uterine arteries of all eight patients, acting as an empirical or therapeutic embolization agent for the various angiographic findings. N-butyl-2-cyanoacrylate was administered to the target bleeding uterine arteries in the two patients with active contrast extravasation. Technical and clinical success were achieved in all patients (100%) with bleeding cessation and no further related surgical intervention or embolization procedure was required for hemorrhage control. Uterine artery dissection occurred in one patient as a minor complication. Normal menstrual cycles were restored in all patients. Uterine artery embolization is a safe, minimally invasive, and effective management option for controlling post-myomectomy hemorrhage without the need for hysterectomy.

    BACKGROUND This study examined the effect of kaempferol on uterine fibroids in vitro and the underlying mechanism, and investigated the potential of kaempferol as a clinical drug for the treatment of uterine fibroids. MATERIAL AND METHODS Uterine fibroid tissue and surrounding smooth muscle tissue were collected for primary culture. Different concentrations of kaempferol (12 μM, 24 μM, and 48 μM) were used to treat the cells for 24, 48, and 72 hours. Ethanol was used in the control group. A CCK-8 colorimetric assay was used to detect cell proliferation. Real-time PCR and immunoblot were used to detect estrogen receptor (ER), insulin-like growth factor-1 (IGF-1), and vascular endothelial growth factor (VEGF) levels in mRNA and protein. RESULTS The differences in proliferation at different time points and concentrations of kaempferol were statistically significant. The inhibitory effect of kaempferol on mRNA levels of ER and IGF, and protein levels of ER, VEGF, and IGF-1 were positively correlated with kaempferol concentration. Changes in kaempferol concentration showed no effect on VEGF mRNA expression. Treatment with kaempferol significantly lowered myocardin levels in uterine fibroid tissue compared to normal uterine smooth muscle (PKaempferol might be used for clinical treatment of uterine fibroids due to its inhibitory effect on the proliferation of uterine fibroids cells.

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

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

    Uterine myomas and adenomyosis are common findings, in particular in patients with symptoms of abdominal enlargement, pelvic pressure, abnormal uterine bleeding, dysmenorrhea, and dyspareunia. Diagnosis and differentiation between the 2 entities are critical in establishing treatment options and the operative approach for surgical management. Herein are reviewed diagnostic options, their relative accuracy, and the effect of accurate diagnosis on treatment. A review was performed using PubMed, MdConsult, OVID, and reviews including cross-referenced articles and prospective and retrospective studies published from 1980 to 2013. Also reviewed are use of ultrasound with its various methods, magnetic resonance imaging, computed tomography, and positron emission tomography in the diagnosis, pretreatment evaluation, and differentiation of myomas and adenomyosis.

    Deep veins (DVs) can be compressed by a uterus enlarged with fibroids. The purpose of this study was to assess the degree of luminal narrowing of DVs caused by a myomatous uterus, and the change in DV narrowing in women with symptomatic fibroids after embolization using time-of-flight (TOF)-magnetic resonance venography (MRV). Twenty-nine consecutive women with symptomatic uterine fibroids underwent TOF-MRV and pelvic MRI before and 4 months after embolization. Based on the TOF-MRV, we evaluated the luminal narrowing of three DVs, including the inferior vena cava, and the bilateral common and external iliac veins, and divided the findings into three grades. The scores for each DV were added for each patient (lowest, 0; highest, 6). DV scores and symptom severity (SS) scores were compared between the baseline and 4 months after embolization using the paired t-test. The relationship between DV scores and uterine volume was investigated using Pearson's test. DV scores decreased significantly, from 1.52 ± 1.70 at baseline to 0.93 ± 1.56 at 4 months after embolization (p = 0.004). The uterine volume decreased from 948 ± 647 mL at baseline to 617 ± 417 mL at 4 months after embolization (p < 0.001). DV score correlated with uterine volume (r = 0.856, p < 0.001). SS scores decreased from 54.5 ± 14.6 at baseline to 26.8 ± 15.4 at 4 months after embolization (p < 0.001). In conclusion, the degree of luminal narrowing of DVs caused by a uterus with fibroids is correlated with the uterine volume. Uterine artery embolization may induce an improvement of luminal narrowing of DVs due to a reduction of the myomatous uterus volume.

    Objective: To investigate the impact of uterine artery embolization (UAE) for leiomyomas of uterus on serum level of sex hormones. Methods: UAE were performed on 31 patients with leiomyomas of uterus. Changes of menses were followed up within 3-6 months after UAE. Serum levels of sex hormones, including FSH, LH, Prog, E2 were tested before and 3 months or 6 months after UAE; and simultaneously with recording the tumor size and the changes of blood dynamics by color Doppler. Results: Twenty-five patients (80.6%)with menorrhagia resumed normal after UAE, and a transient menstrual disorder occurred in 4 patients (12.9%). Only 2 patients (0.06%)aged 45 years and 49 years became menopausal following the procedure. Serum levels of sex hormones showed no significant difference before and 3 months or 6 months after UAE (P>0.05)in 31 patients. Conclusion: UAE is an effective treatment for uterine leiomyomas and possesses no influence on serum levels of sex hormones. However, for patients aged 45 or older, there is possibility of menopause.

    Full Text Available OBJECTIVE: This study reports the first four cases of a uterine transplant procedure conducted in sheep in Latin America. The aim of this study was to evaluate the success of uterine transplantation in sheep. METHOD: The study was conducted at Laboratory of Medical Investigation 37 (LIM 37 at the University of São Paulo School of Medicine. Four healthy mature ewes weighing 40-60 kg were used as both the donor and recipient for a transplant within the same animal (auto-transplant. Institutional guidelines for the care of experimental animals were followed. RESULTS: The first two cases of auto-transplant were performed to standardize the technique. After complete uterine mobilization and isolation of the blood supply, the unilateral vascular pedicle was sectioned and anastomosed on the external iliac vessels. After standardization, the protocol was implemented. Procurement surgery was performed without complications or bleeding. After isolation of uterine arteries and veins as well as full mobilization of the uterus, ligation of the distal portion of the internal iliac vessels was performed with subsequent division and end-to-side anastomosis of the external iliac vessels. After vaginal anastomosis, the final case presented with arterial thrombosis in the left uterine artery. The left uterine artery anastomosis was re-opened and flushed with saline solution to remove the clot from the artery lumen. Anastomosis was repeated with restoration of blood flow for a few minutes before another uterine artery thrombosis appeared on the same side. All four animals were alive after the surgical procedure and were euthanized after the experimental period. CONCLUSION: We describe the success of four uterine auto-transplants in sheep models.

    Recent advances in assisted reproductive technology (ART) have made it possible to circumvent many causes of male and female infertility. The right to have a child by ART has been respected for infertile couples. However, there are currently no legal regulations concerning ART in Japan, and this has resulted in social and ethical problems. Surrogacy involves particularly complex medical, ethical, social, and legal issues, and is frequently focused on as a major social concern. Uterine transplantation (UTx) is a potential alternative for young women with uterine factor infertility due to hysterectomy for treatment of a malignant uterine tumor or massive blood loss after delivery, or because of a congenital disease such as Mayer-Rokitansky-Küster syndrome. UTx has been examined in experimental animals as a basis for establishment of fecundity for young women with uterine factor infertility. In this review, we focus on surrogacy in Japan and UTx research, and discuss the current status and concerns in this field. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    To evaluate the significance of vaginal air seen on CT scan in preoperative staging of uterine cervical carcinoma. A comparison was made between CT findings of vaginal fir and true vaginal involvement status in 85 patients with uterine cervical carcinoma. CT findings were analyzed in terms of the presence or absence of vaginal air, number of CT slices in which vaginal air was seen, shape of vaginal air, and relation of vaginal air to cervical mass. Vaginal air was present in 35 patients and was absent in 50. Although the mere presence of vaginal air or multiplicity of CT slices showing vaginal air did not signify the presence of vaginal involvement, vaginal air with irregular margin or vaginal air adjacent to uterine cervical mass was suggestive of vaginal involvement. These observation of vaginal air in interpreting CT may be helpful in the preoperative staging of uterine cervical carcinoma

    Full Text Available Induced pluripotent stem cells (iPSC are a promising cell source for cartilage regenerative medicine; however, the methods for chondrocyte induction from iPSC are currently developing and not yet sufficient for clinical application. Here, we report the establishment of a fluorescent indicator system for monitoring chondrogenic differentiation from iPSC to simplify screening for effective factors that induce chondrocytes from iPSC. We generated iPSC from embryonic fibroblasts of Col2a1-EGFP transgenic mice by retroviral transduction of Oct4, Sox2, Klf4, and c-Myc. Among the 30 clones of Col2a1-EGFP iPSC we established, two clones showed high expression levels of embryonic stem cell (ESC marker genes, similar to control ESC. A teratoma formation assay showed that the two clones were pluripotent and differentiated into cell types from all three germ layers. The fluorescent signal was observed during chondrogenic differentiation of the two clones concomitant with the increase in chondrocyte marker expression. In conclusion, Col2a1-EGFP iPSC are useful for monitoring chondrogenic differentiation and will contribute to research in cartilage regenerative medicine.

  16. SEX STEROIDS MODULATE UTERINE-PLACENTAL VASCULATURE: IMPLICATIONS FOR OBSTETRICS AND NEONATAL OUTCOMES

    Directory of Open Access Journals (Sweden)

    Manuel eMaliqueo

    2016-04-01

    Full Text Available Adequate blood supply to the uterine-placental region is crucial to ensure the transport of oxygen and nutrients to the growing fetus. Multiple factors intervene to achieve appropriate uterine blood flow and the structuring of the placental vasculature during the early stages of pregnancy. Among these factors, oxygen concentrations, growth factors, cytokines and steroid hormones are the most important. Sex steroids are present in extremely high concentrations in the maternal circulation and are important paracrine and autocrine regulators of a wide range of maternal and placental functions. In this regard, progesterone and estrogens act as modulators of uterine vessels and decrease the resistance of the spiral uterine arteries. On the other hand, androgens have the opposite effect, increasing the vascular resistance of the uterus. Moreover, progesterone and estrogens modulate the synthesis and release of angiogenic factors by placental cells, which regulates trophoblastic invasion and uterine artery remodeling. In this scenario, it is not surprising that women with pregnancy-related pathologies, such as early miscarriages, preterm delivery, preeclampsia and fetal growth restriction, exhibit altered sex steroid concentrations.

    1985-01-01

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

    Full Text Available Background. Diverticulum, one of the long-term sequelae of cesarean section, can cause abnormal uterine bleeding and increase the risk of uterine scar rupture. In this study, we aimed to evaluate the efficacy of combined laparoscopic and hysteroscopic repair, a newly occurring method, treating post-cesarean section uterine scar diverticulum. Methods. Data relating to 40 patients with post-cesarean section uterine diverticulum who underwent combined laparoscopic and hysteroscopic repair were retrospectively analyzed. Preoperative clinical manifestations, size of uterine defects, thickness of the lower uterine segment (LUS, and duration of menstruation were compared with follow-up findings at 1, 3, and 6 months after surgery. Results. The average preoperative length and width of uterine diverticula and thickness of the lower uterine segment were recorded and analyzed. The average durations of menstruations at 1, 3, and 6 months after surgery were significantly shorter than the preoperative one (p<0.05, respectively. At 6 months after surgery, the overall success improvement rate of surgery was 90% (36/40. Three patients (3/40 = 7.5% developed partial improvement, and 1/40 (2.5% was lost to follow-up. Conclusions. Our findings showed that combined treatment with laparoscopy and hysteroscopy was an effective method for the repair of post-cesarean section uterine diverticulum.

    Objective: To discuss the method of constructing digital 3D arterial vascular network of uterine leiomyomas based on the CTA data, by which to lay the fundamental work for the observation of the origin and distribution of hysteromyoma blood supply. Methods: A total of 64 cases of uterine leiomyomas were enrolled in this study. Dual-source CT angiography was performed in all the patients, and the CTA original images were obtained. By using Mimics 10.01 software the digital 3D arterial vascular network of uterine was reconstructed. The reconstructed models were analyzed. Results: (1) The constructing process of arterial vascular network was successfully accomplished in all 64 patients. The pelvic main arteries, the uterine arteries and tumor-feeding arteries as well as the blood distribution type were clearly demonstrated on the reconstructed images. (2) The origins of hysteromyoma blood supply included uterine artery (81.25%), uterine artery and unilateral ovarian artery (10.94%), uterine artery and bilateral ovarian artery (4.69%) and ovarian artery (3.12%). (3) Distribution pattern of blood supply of uterine leiomyomas could be divided into 4 types: (1) Type Ⅰ. The unilateral arterial blood supply dominant type (unilateral uterine artery with or without ipsilateral ovarian arterial, providing more than 1/2 blood supply of hysteromyoma), which accounted for 35.94% of all patients (23/26); (2) Type Ⅱ. The bilateral arterial blood supply balanced type (bilateral uterine artery with or without ipsilateral ovarian artery, providing about 1/2 blood supply of hysteromyoma), which accounted for 53.13% of all patients (34/64); (3) Type Ⅲ. The unilateral uterine artery was the main blood supply of uterine leiomyomas, which accounted for 7.81% of all patients (5/64); (4) Type Ⅳ. The ovarian artery was the main blood supply of uterine leiomyomas, which accounted for 3.13% of all patients (3/64). Conclusion: Based on CTA data and with the help of reconstruction

  1. Uterine sarcomas-Recent progress and future challenges

    International Nuclear Information System (INIS)

    Seddon, Beatrice M.; Davda, Reena

    2011-01-01

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

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

    Directory of Open Access Journals (Sweden)

    Isao Kurihara

    2007-06-01

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

    Recent genomic studies have identified subtypes of uterine leiomyoma (LM) with distinctive genetic alterations. Here, we report the elucidation of the biological characteristics of the two most prevalent uterine leiomyoma subtypes, MED12-mutant (MED12-LM) and HMGA2-overexpressing (HMGA2-LM) uterine leiomyomas. Because each tumor carries only one genetic alteration, both subtypes are considered to be monoclonal. Approximately 90% of cells in HMGA2-uterine leiomyoma were smooth muscle cells (SMC) with HMGA2 overexpression. In contrast, MED12-LM consisted of similar numbers of SMC and non-SMC, which were mostly tumor-associated fibroblasts (TAF). Paradoxically, TAF carried no mutations in MED12, suggesting an interaction between SMC and TAF to coordinate their growth. The higher amount of extracellular matrix in MED12-LM than HMGA2-LM was partially due to the high concentration of collagen-producing TAF. SMC growth in a xenograft assay was driven by progesterone in both uterine leiomyoma subtypes. In contrast, TAF in MED12-LM proliferated in response to estradiol, whereas progesterone had no effect. The high concentration of estrogen-responsive TAF in MED12-LM explains the inconsistent discoveries between in vivo and in vitro studies on the mitogenic effect of estrogen and raises questions regarding the accuracy of previous studies utilizing MED12-LM cell culture. In addition, the differential effects of estradiol and progesterone on these uterine leiomyoma subtypes emphasize the importance of subtypes and genotypes in designing nonsurgical therapeutic strategies for uterine leiomyoma.

    To evaluate the usefulness of 'bridging vascular sign' in the diagnosis of a subserosal/exophytic uterine leiomyoma and the helpfulness of this sign in the differentiation of a uterine leiomyoma from adnexal masses on pelovic magnetic resonance (MR) imaging. Of 20 women with a solitiary pelvic mass in whom pelvic MR imaging was performed during recent three years to differentiate a uterine leiomyoma from an adnexal mass, 12 with surgicopathologically proven subserosal/exophytic uterine leiomymas were included in this study. The other eight women were proved to have tubo-ovarian abscess (n=3D3), ovarian endometrioma (n=3D2), ruptured corpus luteum cyst (n=3D2), and ovarian fibroma (n=3D1). A 1.5 T unit was used to obtain axial/saittal T1- and T2-weighted and gadolinum-enhanced sagittal T1-weighted images. Positive 'bridging vascular sign' was defined through the retrospective review and analysis of MR findings as the presence of intervening curvilinear or tortuous signal-void vascular structures crossing the uterus and the pelvic mass. Using this sign in the diagnosis and differentiation of a uterine leiomyoma from adnexal masses, statistical significance was evaluated. 'Bridging vascular sign' was present in eight of 12 leiomyomas, but no in adnexal masses. Using this sign in the diagnosis and differentiation of a uterine leiomyoma from adnexal masses, sensitivity was 66.7%, specificity 100%, positive predictive value 100%, negative predictive value 66.7%, and accuracy 80%. 'Vascular bridging sign' on MR imaging may be a useful radiologic sign in the diagnosis and differentiation of a subserosal/exophytic uterine leiomyoma from adnexal masses.=20

    Full Text Available The aim of this study was to compare clinical and laboratory findings of women with or without uterine leiomyoma.Study group consisted of 82 women with uterine leiomyoma and the control group comprised 42 healthy women. Women’s age, gravity, parity, blood groups, pattern of menstrual cycles, complaints at presentation, fertility, ultrasonographical findings, surgical operations and thyroid function tests were evaluated.There were no significant differences in blood group distribution, gravity, parity and thyroid function test results between the patients and the control subjects (P>0.05. A significant difference was found in the complaints at presentation between two groups (P<0.001. Mentrual cycles irregularity was more frequently found in the patients compared with the controls (57.3% vs. 42.9%, respectively, P=0.009. Although no infertile woman was found in the control group, 8.5% of patients were found to have infertility. The sensitivity of ultrasonography was found to be 97.6%. Except for the existence of higher infertility rate and the menstrual cycles irregularities, no significant difference was found in the clinical and laboratory findings between women with or without uterine leiomyoma. Therefore, physical examination and imaging methods are remained as the most important diagnostic tools for uterine leiomyoma.

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

    Platelet-derived growth factor receptor α (PDGFRα) expression is frequently observed in many kinds of cancer and is a candidate for therapeutic targeting. This preclinical study evaluated the biologic significance of PDGFRα and PDGFRα blockade (using a fully humanized monoclonal antibody, 3G3) in uterine cancer. Expression of PDGFRα was examined in uterine cancer clinical samples and cell lines, and biologic effects of PDGFRα inhibition were evaluated using in vitro (cell viability, apoptosis, and invasion) and in vivo (orthotopic) models of uterine cancer. PDGFRα was highly expressed and activated in uterine cancer samples and cell lines. Treatment with 3G3 resulted in substantial inhibition of PDGFRα phosphorylation and of downstream signaling molecules AKT and mitogen-activated protein kinase (MAPK). Cell viability and invasive potential of uterine cancer cells were also inhibited by 3G3 treatment. In orthotopic mouse models of uterine cancer, 3G3 monotherapy had significant antitumor effects in the PDGFRα-positive models (Hec-1A, Ishikawa, Spec-2) but not in the PDGFRα-negative model (OVCA432). Greater therapeutic effects were observed for 3G3 in combination with chemotherapy than for either drug alone in the PDGFRα-positive models. The antitumor effects of therapy were related to increased apoptosis and decreased proliferation and angiogenesis. These findings identify PDGFRα as an attractive target for therapeutic development in uterine cancer. ©2014 American Association for Cancer Research.

    To assess placental perfusion during spontaneous or induced uterine contraction in labor at term using placental vascular sonobiopsy (PVS) by 3D power Doppler ultrasound with the VOCAL imaging analysis program. PVS was performed in 50 normal pregnancies (32 in spontaneous labor group [SLG], and 18 in induced labor group with oxytocin or prostaglandin F2α [ILG]) at 37-41 weeks of gestation to assess placental perfusion during uterine contraction in labor. Only pregnancies with an entirely visualized anterior placenta were included in the study. Data acquisition was performed before, during (at the peak of contraction), and after uterine contraction. 3D power Doppler indices such as the vascularization index (VI), flow index (FI), and vascularization flow index (VFI) were calculated in each placenta. There were no abnormal fetal heart rate tracings during contraction in either group. VI and VFI values were significantly reduced during uterine contraction in both groups (SLG, -33.4% [-97.0-15.2%], and ILG, -49.6% [-78.2--4.0%]), respectively (P power Doppler indices (VI, FI, and VFI) during uterine contraction (at the peak of contraction) showed a correlation greater than 0.7, with good intra- and inter-observer agreements. Our findings suggest that uterine contraction in both spontaneous and induced labors causes a significant reduction in placental perfusion. Reduced placental blood flow in induced uterine contraction has a tendency to be marked compared with that in spontaneous uterine contraction. To the best of our knowledge, this is the first study on the non-invasive assessment of placental perfusion during uterine contraction in labor using 3D power Doppler ultrasound. However, the data and their interpretation in the present study should be taken with some degree of caution because of the small number of subjects studied. Further studies involving a larger sample size are needed to assess placental perfusion and vascularity using PVS during normal and

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

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

    The aim of the study was to assess the clinical outcomes of surgical repair of uterine cesarean scar defects with sonography (US). Seven nonpregnant women with history of cesarean section and a large uterine scar defect were enrolled. The surgical repair was performed by minilaparotomy. The US assessment of the uterine scar was performed using a standardized approach at baseline, then at a first visit 2-3 days following the surgical intervention (V1) and at a follow-up visit 3 months later (V2). Residual myometrial thickness (RMT), width, and depth of the scar defect were measured. The mean RMT increased significantly from 1.9 mm at baseline to 8.8 mm at V1 and 8.0 mm at V2. No intraoperative complications were observed. Postmenstrual spotting and abdominal pain reported preoperatively resolved after the operation. A surgical repair procedure for an incompletely healed uterine cesarean scar is effective in increasing RMT thickness, decreasing the depth of the scar, and reducing symptoms related to the cesarean section scar defect. Further studies on post-repair pregnancy outcomes are required to evaluate whether the procedure affects the rate of cesarean scar pregnancy, morbidly adherent placenta, and/or uterine scar dehiscence and rupture. The repair of a cesarean scar defect is recommended only for symptomatic women. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 45:455-460, 2017. © 2017 Wiley Periodicals, Inc.

    Race, specifically African ancestry, and obesity are important risk factors for uterine fibroids, and likely interact to provide the right conditions for fibroid growth. However, existing studies largely focus on the main-effects rather than their interaction. Here, we firstly provide evidence for interaction between categories of body mass index (BMI) and reported-race in relation to uterine fibroids. We then investigate whether the association between inferred local European ancestry and fibroid risk is modified by BMI in African American (AA) women in the Vanderbilt University Medical Center bio-repository (BioVU) (539 cases and 794 controls) and the Coronary Artery Risk Development in Young Adults study (CARDIA, 264 cases and 173 controls). We used multiple logistic regression to evaluate interactions between local European ancestry and BMI in relation to fibroid risk, then performed fixed effects meta-analysis. Statistical significance threshold for local-ancestry and BMI interactions was empirically estimated with 10,000 permutations (p-value = 1.18x10-4). Admixture mapping detected an association between European ancestry and fibroid risk which was modified by BMI (continuous-interaction p-value = 3.75x10-5) around ADTRP (chromosome 6p24); the strongest association was found in the obese category (ancestry odds ratio (AOR) = 0.51, p-value = 2.23x10-5). Evaluation of interaction between genotyped/imputed variants and BMI in this targeted region suggested race-specific interaction, present in AAs only; strongest evidence was found for insertion/deletion variant (6:11946435), again in the obese category (OR = 1.66, p-value = 1.72x10-6). We found nominal evidence for interaction between local ancestry and BMI at a previously reported region in chromosome 2q31-32, which includes COL5A2, and TFPI, an immediate downstream target of ADTRP. Interactions between BMI and SNPs (single nucleotide polymorphisms) found in this region in AA women were also detected in an

    Uterine receptivity to embryo implantation depends on appropriate progesterone (P4) and estrogen stimulation. P4 rapidly stimulates production of the morphogen Indian hedgehog (IHH) in murine uterine epithelium as well as downstream molecules in the hedgehog pathway such as Patched homolog 1 (PTCH1) and nuclear receptor subfamily 2, group F, member 2 (NR2F2) in uterine stroma. Studies using IHH-null mice indicate that IHH is obligatory for the normal P4 response in the uterus. To determine whether IHH induction in uterine epithelium is mediated through P4 receptor (PR) in epithelium (E) and/or stroma (S), we produced tissue recombinants using uteri from neonatal PR knockout (ko) mice and wild-type (wt) mice containing PR in S and/or E or lacking PR altogether using a tissue recombinant methodology and assessed their response to P4. In tissue recombinants containing wt-S (wt-S + wt-E and wt-S + ko-E), P4 induced Ihh mRNA expression at 6 h that was 6-fold greater than in oil-treated controls (P Ihh mRNA expression was unaffected by P4 in ko-S + ko-E and ko-S + wt-E grafts despite epithelial PR expression in the latter. Nr2f2 and Ptch1 mRNA expression was similar in that it was stimulated by P4 only in recombinants containing stromal PR. These results indicate that stromal PR is both necessary and sufficient for P4 stimulation of epithelial IHH as well as downstream events such as PTCH1 and NR2F2 increases in stroma.

    Obstetrical emergencies are problem in veterinary clinics and hospital. So, the aim of this report is to describe the clinical-surgical aspect of one of them, the uterine prolapse. Complete protrusion and retroflexion of uterus had been diagnosed in a queen and female dog, respectively. After the stabilization of the animals and reduction of the prolapses followed by ovary-hysterectomy, one of the animals came to death due to septicemia and hypovolemic shock. Rapid assessment and intensive treatments are required to sustain the life of the animal.

    KEY WORDS: Cat, dog, uterine prolapse, uterine retroflexion.

    Emergências obstétricas, como o prolapso uterino, constituem um problema em clínicas e hospitais veterinários. Neste relato descreve-se o aspecto clínico-cirúrgico do prolapso uterino. Diagnosticaram-se, em uma gata e em uma cadela, protrusão completa e retroflexão uterina, respectivamente. Após a estabilização dos animais e redução dos prolapsos seguidos de ovário-histerectomia, um dos animais veio a óbito, em decorrência de septicemia e choque hipovolêmico. Portanto, a rápida avaliação e tratamentos intensivos são requeridos para assegurar a vida do animal.

    Full Text Available Uterine prolapse is extremely rare during pregnancy. Prolapse etiology depends on many factors, such as advanced age, multiparity, difficult vaginal delivery and increased body mass index. This condition may be complicated by cervical desiccation and ulceration, preterm labor, obstructive labor and even maternal death. We report a case of uterine prolapse which developed during pregnancy. A 40-year-old woman gravida 5 para 4 with stage 3 uterine prolapse was admitted to hospital with pelvic pain and urinary tract infection at 35th week of the gestation. A cesarean section was performed at 38th week of the gestation because of profound cervical bleeding due to the edematous, ulcerated, desiccated cervix. Postnatally, the uterine prolapse spontaneously recovered. Uterine prolapse that occurs during the pregnancy should be managed using a conservative approach. It seems that severely desiccated cervix cause profound bleeding and cesarean delivery should be preferred.

    Full Text Available The current study aims to evaluate histopathological and digital morphometrical aspects associated with uterine leiomyomas in one hundred and fifty (150 patients diagnosed with leiomyoma. Uterine tissues were subjected to the histopathological and digital morphometric analyses of the interstitial collagen distribution. The analysis of medical records indicates that most of the women diagnosed with uterine leiomyomas (68.7% are between 37 and 48 years old. As for the anatomic location of the tumors, approximately 61.4% of the patients had intramural and subserosal lesions. In 50% of the studied cases, the patients developed uterine leiomyomatosis (with more than eight tumors. As for the morphometric study, the average size of the interstitial collagen distribution held approximately 28.53% of the capture area, whereas it was of 7.43% in the normal tissue adjacent to the tumor. Another important aspect observed in the current study was the high rate of young women subjected to total hysterectomy, a fact that resulted in early and definitive sterility.

    Objective: To evaluate super-selective uterine arterial chemoembolization therapy in the treatment of cervical cancer. Methods: Bilateral uterine arterial infusion with DDP, EADM or THP, MMC and 5-Fu was performed in 56 patients with pathologically-proved cervical cancer, which was followed by embolization of uterine arteries with iodine emulsion and Gelfoam particles. Radical hysterectomy was performed in 6 patients after interventional treatment. Results: Embolization of bilateral uterine arteries were successfully carried out in all cases. The angiography conducted during the procedure revealed markedly dilated uterine arteries, spiral tumor-feeding arteries and obvious tumor staining. The total effective rate was up to 94.6%. Six patients received radical hysterectomy 2 weeks after arterial chemoembolization, and the blood loss during the operation was much less than usual and the surgery procedure took shorter time. Ovarian necrosis was found in 1 case. The main adverse effects included leukocytopenia, nausea, vomiting and abdominal pain. Conclusion: Super-selective uterine arterial chemoembolization is a safe and effective supplementary therapy for cervical carcinoma with fewer complications. (authors)

  5. 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.

    The objectives were to: (1) describe the chronology of early embryonic development from ovulation to entry into the uterus; and (2) to determine the timing of embryo migration to the left uterine horn when ovulation occurred from the right ovary. The experiment was conducted in Peru. Females (n = 132) were randomly assigned to 15 experimental groups. All females were mated to an intact male, given 50 μg GnRH im (Cystorelin) and ovulation time determined by transrectal ultrasonography, conducted every 6 hours, starting 24 hours postmating. Animals were slaughtered at a specific intervals postovulation and reproductive tracts were recovered and subjected to oviductal and uterine flushing for females slaughtered between 1 and 6 days postovulation (dpo; Day 0 = ovulation) and uterine flushing for females slaughtered from 7 to 15 dpo for recovery of oocytes/embryos. Season of mating did not influence the interval from mating to ovulation (winter: 29 ± 6 hours vs. summer: 30 ± 6 hours; P = 0.49). Ovulation rates for females mated during winter and summer were 92% versus 100%, respectively (P = 0.05). Fertilization rates for winter and summer mated females were 72% and 82% (P = 0.29). Unfertilized ova were not retained in the uterine tube. All embryos collected were in the uterine tube ipsilateral to the side of ovulation between 1 and 5 dpo. Embryos reached the uterus on 6 dpo. Embryos began to elongate on 9 dpo; at this time, 83% of embryos derived from right-ovary ovulations were collected from the left uterine horn. Embryos occupied the entire uterine cavity by 10 dpo. In conclusion, we characterized early embryo development and location of embryo during its early developmental stages in alpaca. This was apparently the first report regarding chronology of embryo development and migration to the left horn in alpaca which merits further investigation regarding its role in maternal recognition of pregnancy.

    Abnormal uterine bleeding is the direct cause of a significant health care burden for women, their families, and society as a whole. Up to 30% of women will seek medical assistance for this problem during their reproductive years. This guideline replaces previous clinical guidelines on the topic and is aimed to enable health care providers with the tools to provide the latest evidence-based care in the diagnosis and the medical and surgical management of this common problem. To provide current evidence-based guidelines for the diagnosis and management of abnormal uterine bleeding (AUB) among women of reproductive age. Outcomes evaluated include the impact of AUB on quality of life and the results of interventions including medical and surgical management of AUB. Members of the guideline committee were selected on the basis of individual expertise to represent a range of practical and academic experience in terms of location in Canada, type of practice, subspecialty expertise, and general gynaecology background. The committee reviewed relevant evidence in the English medical literature including published guidelines. Recommendations were established as consensus statements. The final document was reviewed and approved by the Executive and Council of the SOGC. This document provides a summary of up-to-date evidence regarding diagnosis, investigations, and medical and surgical management of AUB. The resulting recommendations may be adapted by individual health care workers when serving women with this condition. Abnormal uterine bleeding is a common and sometimes debilitating condition in women of reproductive age. Standardization of related terminology, a systematic approach to diagnosis and investigation, and a step-wise approach to intervention is necessary. Treatment commencing with medical therapeutic modalities followed by the least invasive surgical modalities achieving results satisfactory to the patient is the ultimate goal of all therapeutic interventions

    Full Text Available OBJECTIVE: Minimally invasive methods are used as alternatives to treat leiomyomas and include uterine artery embolization, which has emerged as a safe, effective method. This study aims to evaluate the magnetic resonance imaging predictors for a reduction in leiomyoma volume in patients undergoing uterine artery embolization. METHODS: This prospective longitudinal study was performed at a university hospital. We followed 50 symptomatic premenopausal women with uterine leiomyomas who underwent uterine artery embolization. We examined 179 leiomyomas among these patients. Magnetic resonance imaging was performed one month before and six months after uterine artery embolization. Two radiologists who specialized in abdominal imaging independently interpreted the images. Main Outcome Measures: The magnetic resonance imaging parameters were the uterus and leiomyomas volumes, their localizations, contrast perfusion pattern and node-to-muscle ratio. RESULTS: Six months after treatment, the average uterine volume reduction was 38.91%, and the leiomyomas were reduced by 55.23%. When the leiomyomas were submucosal and/or had a higher node-to-muscle ratio in the T2 images, the volume reduction was even greater (greater than 50%. Other parameters showed no association. CONCLUSIONS: We conclude that symptomatic uterine leiomyomas in patients undergoing uterine artery embolization exhibit volume reductions greater than 50% by magnetic resonance imaging when the leiomyomas are submucosal and/or had a high node-to-muscle ratio in the T2 images.

    Full Text Available Introduction. Uterine fibroid tumors (uterine leiomyomas are the most common benign uterine tumors. The incidence of uterine fibroid tumors increases in older women and may occur in more than 30% of women aged 40 to 60. Many uterine fibroid tumors are asymptomatic and are diagnosed incidentally. Case Presentation. A 44-year-old woman was admitted to our hospital with general weakness, dyspepsia, abdominal distension, and a palpable abdominal mass. An abdominal computed tomography scan showed a huge tumor mass in the abdomen which was compressing the intestine and urinary bladder. Gastroduodenal endoscopic and biopsy results showed a Borrmann type IV gastric adenocarcinoma. The patient was diagnosed with gastric cancer with disseminated peritoneal carcinomatosis. She underwent a hysterectomy with both salphingo-oophorectomy and bypass gastrojejunostomy. Simultaneous uterine fibroid tumor with other malignancies is generally observed without resection. But in this case, a surgical resection was required to resolve an intestinal obstruction and to exclude the possibility of a metastatic tumor. Conclusion. When a large pelvic or ovarian mass is detected in gastrointestinal malignancy patients, physicians try to exclude the presence of a Krukenberg tumor. If the tumors cause certain symptoms, surgical resection is recommended to resolve symptoms and to exclude a metastatic tumor.

    To determine the expression of miR-29c and its target genes in leiomyoma and the role of NF-κB, specific protein 1 (SP1), and DNA methylation in its regulation. Experimental study. Academic research laboratory. Women undergoing hysterectomy for leiomyoma. Over- and underexpression of miR-29c; blockade of transcription factors. MiR-29c and its target gene levels in leiomyoma and the effects of blockade of transcription factors on miR-29c expression. Leiomyoma as compared with myometrium expressed significantly lower levels of miR-29c, with an inverse relationship with expression of its targets, COL3A1 and DNMT3A. Gain of function of miR-29c inhibited the expression of COL3A1 and DNMT3A at protein and mRNA levels, secreted COL3A1, and rate of cell proliferation. Loss of function of miR-29c had the opposite effect. E2, P, and their combination inhibited miR-29c in leiomyoma smooth muscle cells (LSMC). Phosphorylated NF-κB (p65) and SP1 protein expression were significantly increased in leiomyoma. SiRNA knockdown of SP1 and DNMT3A or their specific inhibitors significantly increased the expression of miR-29c, accompanied by the inhibition of cellular and secreted COL3A1 in siRNA-treated cells. Knockdown of p65 also induced miR-29c expression but had no effect on COL3A1 expression. MiR-29c expression is suppressed in leiomyoma, resulting in an increase in expression of its targets COL3A1 and DNMT3A. The suppression of miR-29c in LSMC is primarily mediated by SP1, NF-κB signaling, and epigenetic modification. Collectively, these results indicate a significant role for miR-29c in leiomyoma pathogenesis. Copyright © 2016 American Society for Reproductive Medicine. Published by Elsevier Inc.

    Full Text Available Dysfunctional uterine bleeding is a common presentation of women in the emergency department. We describe the case of a 33-year-old female who presented with intermittent spotting due to an acquired uterine AVF. The patient underwent a transvaginal pelvic ultrasound as well as a CT angiogram. The patient was treated conservatively and elected to undergo uterine artery embolization in an effort to preserve fertility. She successfully delivered a healthy baby boy at 39-week gestation via an emergent caesarian section due to a prolapsed umbilical cord 17 months after undergoing the uterine artery embolization.

    Female pigs were assigned to three groups at 94 days of age: a control group (CTR), a group undergoing the ligation and severing of the left oviduct (LIG), and a group undergoing right hysteroovariectomy (HHO). They were inseminated at 307 days of age. At 35 days of pregnancy, an ultrasonic transit time flow probe was implanted around the middle artery of one uterine horn in 33 sows and uterine blood flow was measured during thirteen 24-h periods between 44 and 111 days. Despite large differences in ovulation rate per uterine horn (4.8, 8.3 and 16.9 in the LIG, CTR and HHO groups, respectively), variation of litter size was considerably reduced with advancement of pregnancy (3.0, 6.6 and 10.8 foetuses per uterine horn at 35 days, and 3.0, 5.8 and 4.9 at 112 days (slaughter), respectively). Uterine blood flow increased linearly during pregnancy. It was lower in the LIG sows (0.82 to 1.74 L x min(-1) x horn(-1) from 44 to 111 days) than in the CTR and HHO sows (1.22 to 2.84 and 1.09 to 2.63 L x min(-1) x horn(1), respectively). It was more closely related to litter weight than to litter size and amounted to 0.42 L x min(-1) x kg foetus(-1) at 111 days. Uterine blood flow per foetus decreased when litter size increased. It increased from 0.31 to 0.72, 0.26 to 0.60 and 0.20 to 0.43 L x min(-1) x foetus(-1) from 44 to 111 days when there were 2 to 3, 4 to 5, and 6 to 8 foetuses in the uterine horn, respectively. This explains why piglets from large litters are lighter at birth.

    Proper functioning of the meniscus depends on the composition and organization of its fibrocartilaginous extracellular matrix. We previously demonstrated that the avascular inner meniscus has a more chondrocytic phenotype compared with the outer meniscus. Inhibition of the Rho family GTPase ROCK, the major regulator of the actin cytoskeleton, stimulates the chondrogenic transcription factor Sry-type HMG box (SOX) 9-dependent α1(II) collagen (COL2A1) expression in inner meniscus cells. However, the crosstalk between ROCK inhibition, SOX9, and other transcription modulators on COL2A1 upregulation remains unclear in meniscus cells. The aim of this study was to investigate the role of SOX9-related transcriptional complex on COL2A1 expression under the inhibition of ROCK in human meniscus cells. Human inner and outer meniscus cells were prepared from macroscopically intact lateral menisci. Cells were cultured in the presence or absence of ROCK inhibitor (ROCKi, Y27632). Gene expression, collagen synthesis, and nuclear translocation of SOX9 and Smad2/3 were analyzed. Treatment of ROCKi increased the ratio of type I/II collagen double positive cells derived from the inner meniscus. In real-time PCR analyses, expression of SOX9 and COL2A1 genes was stimulated by ROCKi treatment in inner meniscus cells. ROCKi treatment also induced nuclear translocation of SOX9 and phosphorylated Smad2/3 in immunohistological analyses. Complex formation between SOX9 and Smad3 was increased by ROCKi treatment in inner meniscus cells. Chromatin immunoprecipitation analyses revealed that association between SOX9/Smad3 transcriptional complex with the COL2A1 enhancer region was increased by ROCKi treatment. This study demonstrated that ROCK inhibition stimulated SOX9/Smad3-dependent COL2A1 expression through the immediate nuclear translocation of Smad3 in inner meniscus cells. Our results suggest that ROCK inhibition can stimulates type II collagen synthesis through the cooperative activation

    Full Text Available Purpose. Uterine artery embolization is a minimally invasive technique. It applies the principle of targeted anatomical structure devascularisation with utility in fibroid conservative therapy, including for future fertility preserving status. The objective of our paper represents a description and evaluation of angiography utility as a predictive method for fertility maintenance. Material and Methods. The angiography and ultrasound aspects obtained from a prospective study in which selected patients have undergone uterine artery embolization for fertility preservation are detailed. Results. The following angiography aspects have been detected: left- right shunt and utero-ovarian collaterals; these have been compared with the ultrasound aspects related to the fibroid evolution form a volumetric and Doppler ultrasound point of view. The angiographical description predicts the impact on post embolization fibroid evolution and upon fertility. An analysis is made in order to assess the way in which angiography can contribute to fertility alteration. Conclusions. The angiography aspects during embolization and the following ultrasound aspects can represent predictive factors as to fertility evolution after uterine artery embolization.

  1. Target Therapies for Uterine Carcinosarcomas: Current Evidence and Future Perspectives

    Full Text Available Carcinosarcomas (CS in gynecology are very infrequent and represent only 2–5% of uterine cancers. Despite surgical cytoreduction and subsequent chemotherapy being the primary treatment for uterine CS, the overall five-year survival rate is 30 ± 9% and recurrence is extremely common (50–80%. Due to the poor prognosis of CS, new strategies have been developed in the last few decades, targeting known dysfunctional molecular pathways for immunotherapy. In this paper, we aimed to gather the available evidence on the latest therapies for the treatment of CS. We performed a systematic review using the terms “uterine carcinosarcoma”, “uterine Malignant Mixed Müllerian Tumors”, “target therapies”, “angiogenesis therapy”, “cancer stem cell therapy”, “prognostic biomarker”, and “novel antibody-drug”. Based on our results, the differential expression and accessibility of epithelial cell adhesion molecule-1 on metastatic/chemotherapy-resistant CS cells in comparison to normal tissues and Human Epidermal Growth Factor Receptor 2 (HER2 open up new possibilities in the field of target therapy. Nevertheless, future investigations are needed to clarify the impact of these new therapies on survival rate and medium-/long-term outcomes.

    The association of uterine leiomyoma with increased risk of breast cancer is controversial. Therefore, we used the National Health Insurance Research Database of Taiwan to examine breast cancer incidence and mortality among Asian patients with and without uterine leiomyoma. We compared breast cancer incidence and mortality between 22,001 newly diagnosed uterine leiomyoma patients and 85,356 individuals without uterine leiomyoma matched by age and date of diagnosis. Adjusted hazard ratios for breast cancer were estimated using the Cox model. The incidence of breast cancer was 35% higher in the uterine leiomyoma group than the leiomyoma-free group (1.65 vs. 1.22 per 1,000 individuals, p leiomyoma group (mean followed time, 3.59 ± 2.70 years) than the leiomyoma-free group (8.78%; mean followed time, 3.54 ± 2.67 years) at the endpoint of the study (p leiomyoma than in those without it, but overall mortality from breast cancer was lower in the patients with uterine leiomyoma.

    Abnormal uterine bleeding (AUB) is the major complaint in approximately one-third of gynecological visits in premenopausal women, and in >70% of appointments of perimenopausal and postmenopausal women. Uterine myoma is one of the main causes of AUB during menacme, especially when it is submucosal. The association of myoma and AUB may be related to several factors, from local alterations of angiogenic and vasoactive substances to changes in uterine contractility. The objective of this paper is to show the different associations of myoma and AUB. Copyright © 2016. Published by Elsevier Ltd.

    2016-01-01

    In the treatment of women with abnormal uterine bleeding, once a thorough history, physical examination, and indicated imaging studies are performed and all significant structural causes are excluded, medical management is the first-line approach. Determining the acuity of the bleeding, the patient's medical history, assessing risk factors, and establishing a diagnosis will individualize their medical regimen. In acute abnormal uterine bleeding with a normal uterus, parenteral estrogen, a multidose combined oral contraceptive regimen, a multidose progestin-only regimen, and tranexamic acid are all viable options, given the appropriate clinical scenario. Heavy menstrual bleeding can be treated with a levonorgestrel-releasing intrauterine system, combined oral contraceptives, continuous oral progestins, and tranexamic acid with high efficacy. Nonsteroidal antiinflammatory drugs may be utilized with hormonal methods and tranexamic acid to decrease menstrual bleeding. Gonadotropin-releasing hormone agonists are indicated in patients with leiomyoma and abnormal uterine bleeding in preparation for surgical interventions. In women with inherited bleeding disorders all hormonal methods as well as tranexamic acid can be used to treat abnormal uterine bleeding. Women on anticoagulation therapy should consider using progestin-only methods as well as a gonadotropin-releasing hormone agonist to treat their heavy menstrual bleeding. Given these myriad options for medical treatment of abnormal uterine bleeding, many patients may avoid surgical intervention. Copyright © 2016 Elsevier Inc. All rights reserved.

    Ehlers-Danlos syndrome (EDS) is a group of inherited connective tissue disorders characterized by hyperextensible skin, joint hypermobility and soft tissue fragility. For molecular diagnosis, targeted exome sequencing was performed on a 9-year-old male patient who was clinically suspected to have EDS. The patient presented with progressive kyphoscoliosis, joint hypermobility and hyperextensible skin without scars. Ultimately, classical EDS was diagnosed by identifying a novel, mono-allelic mutation in COL5A2 [NM_000393.3(COL5A2_v001):c.682G>A, p.Gly228Arg].

  11. ER stress and basement membrane defects combine to cause glomerular and tubular renal disease resulting from Col4a1 mutations in mice

    Directory of Open Access Journals (Sweden)

    Frances E. Jones

    2016-02-01

    Full Text Available Collagen IV is a major component of basement membranes, and mutations in COL4A1, which encodes collagen IV alpha chain 1, cause a multisystemic disease encompassing cerebrovascular, eye and kidney defects. However, COL4A1 renal disease remains poorly characterized and its pathomolecular mechanisms are unknown. We show that Col4a1 mutations in mice cause hypotension and renal disease, including proteinuria and defects in Bowman's capsule and the glomerular basement membrane, indicating a role for Col4a1 in glomerular filtration. Impaired sodium reabsorption in the loop of Henle and distal nephron despite elevated aldosterone levels indicates that tubular defects contribute to the hypotension, highlighting a novel role for the basement membrane in vascular homeostasis by modulation of the tubular response to aldosterone. Col4a1 mutations also cause diabetes insipidus, whereby the tubular defects lead to polyuria associated with medullary atrophy and a subsequent reduction in the ability to upregulate aquaporin 2 and concentrate urine. Moreover, haematuria, haemorrhage and vascular basement membrane defects confirm an important vascular component. Interestingly, although structural and compositional basement membrane defects occurred in the glomerulus and Bowman's capsule, no tubular basement membrane defects were detected. By contrast, medullary atrophy was associated with chronic ER stress, providing evidence for cell-type-dependent molecular mechanisms of Col4a1 mutations. These data show that both basement membrane defects and ER stress contribute to Col4a1 renal disease, which has important implications for the development of treatment strategies for collagenopathies.

    The aim of this study was to determine the potential usefulness of uterine artery embolization (UAE) for the management of uterine leiomyoma. Sixty nine patients (mean age; 40.3 years, age range; 31-52 years) who underwent UAE for symptomatic fibroids (with menorrhagia, dysmenorrhoea and bulk-related symptoms) from January 2000 to December 2000 were retrospectively analyzed. The mean follow-up period was 3.5 months (range: 1-8 months). The fibroids ranged in size from 2.0 cm to 13.2 cm with a mean size of 5.8 cm. We performed embolization using polyvinyl alcohol particles (250-710 {mu} m). The improvement of the clinical symptoms was analyzed. Reduction of the uterine and predominant fibroid volumes was assessed using MRI. Symptom improvement for the menorrhagia (87.5%), dysmenorrhoea (83.3%) and the bulk-related symptoms (79.2%) was reported. Complications includes ovarian failure in four patients (5.8% of the total patients, mean age: 43.3 yrs) and infection in three patients (4.3% of the total patients) who underwent conservative management with intravenous antibiotics and analgesics. The volume reduction rate of the uterus and the predominant fibroids after uterine artery embolization were 36.3% and 56.6%, respectively. UAE is a promising new treatment for symptomatic fibroids and may be a valuable alternative to hysterectomy.

    A 56 year old nulliparous female Asian elephant (Elephas maximus) living at the zoological garden of Naples (Italy), with a clinical history of recurrent colic, was found in agonal state and humane euthanasia was elected. At necropsy the uterine body was moderately increased in size and the lumen was reduced due to a poorly demarcated and infiltrative neoplasm. Furthermore, multiple, whitish, firm nodules were present in both lungs. Histological examination of the uterine mass revealed epithelial cells arranged in tubular or solid pattern infiltrating the endometrium and the muscular layer. Immunohistochemical examination showed immunoreactivity of neoplastic cells to estrogen receptors antibody. Pulmonary lesions were histologically and immunohistochemically superimposable to the epithelial uterine neoplasm. A definitive diagnosis of uterine adenocarcinoma with pulmonary metastases was made.

    Objective: to analyze the causes of uterine hemorrhage occurred after cesarean section and to investigate the value of angiography and transcatheter artery embolization (TAE) in the diagnosis and treatment of postpartum hemorrhage after cesarean section. Methods: During the period from Jan. 2001 to Dec. 2011, a total of 65 cases suffering from uterine bleeding after cesarean section had underwent uterine arteriography to clarify the diagnosis, which was followed by transcatheter uterine artery embolization (TUAE). The clinical data, the causes of bleeding and the angiographic features were retrospectively analyzed. Results: The causes of uterine bleeding after cesarean section included uterine artery pseudoaneurysm (n=26), uterine atony (n=18), placental factors (n=11), gestational hypertension (n=8), coexisting uterine fibroids (n=1) and uterine bleeding of unknown reason (n=1). Uterine artery angiography revealed contrast extravasation in all patients except one patient. The angiographic findings confirmed the diagnosis of uterine artery bleeding after cesarean section. The bleeding stopped after TUAE, and the patients were in stable condition. No serious complications occurred. Conclusion: Pseudoaneurysm is the primary cause of postpartum uterine hemorrhage after cesarean section. Transcatheter uterine artery angiography can promptly and reliably determine the causes of bleeding, and, at the same time, embolization therapy can be carried out to effectively stop the bleeding.

    Solitary uterine metastases from extragenital cancers are very rare. Breast cancer is the most frequent primary site of metastasis to the uterine corpus, with invasive lobular carcinoma more likely to spread to gynecologic organs than invasive ductal carcinoma. A 62-year-old postmenopausal Japanese woman was diagnosed with uterine leiomyomata more than 20 years ago and had been managed conservatively until menopause. Seven years prior to her presentation, she was diagnosed with breast cancer and underwent a partial resection of her right breast for stage IIA invasive lobular carcinoma. She underwent adjuvant chemotherapy, radiotherapy, and five years of anastrozole hormonal therapy. She presented with a growing uterine mass. Her tumor marker levels were markedly increased over the course of her follow-up, but a systemic examination revealed only a solitary uterine tumor. She underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy. A histopathological examination, including detailed immunohistochemistry, confirmed metastatic invasive lobular carcinoma, infiltrating both her uterine myometrium and fibroid tissue. We report a very rare metastatic pattern of invasive lobular carcinoma and demonstrate that gross cystic disease fluid protein-15 and mammaglobin are useful in the diagnosis of metastatic breast cancer.

    Nikkanen, V.; Salmi, T.; Groenroos, M.

    1980-01-01

    The effectiveness of low-dose intrauterine irradiation for benign diseases and its possible carcinogenic effect on the uterus was studied in 190 patients who were treated during the years 1952-1974. The indications for irradiation were premenopausal functional bleeding, leukemia, hemophilia, fibroids, endometriosis or other benign reason. Radiation was also performed on patients with severe neurologic diseases that contraindicated surgery and on some mentally retarded patients whose restlessness and epileptic seizures were aggravated premenstrually and during menstruation. The mean follow-up period was 15 years. Uterine bleeding recurred in 21 percent of the patients. No cases of uterine malignant degeneration were found. (author)

  19. Unexpected uterine leiomyosarcoma during laparoscopic hysterectomy

    2016-01-01

    Background: Uterine leiomyosarcomas (LMS) have been the subject of much discussion because of cases in which suspected benign leiomyomas have been power morcellated and subsequently have proven to be LMS. Some of these cases have received public attention and have led to the U.S. Food and Drug...... Administration (FDA) issuing a warning against uncontained power morcellation. Case: A 45-year-old woman had a symptomatic uterine fibroid with heavy menstrual bleeding, and incontinence caused by pressure from the fibroid. She had previously received 6 months of treatment with Esmya® (Gedeon Richter, Budapest......, Hungary; ulipristal acetate; UPA), and her symptoms were reduced. However, subsequently in September 2015, she was then admitted to the gynecologic department of a hospital because she had increased pain. A high level of C-reactive protein was found, and necrosis of the fibroid was assumed...

    Lee, Jung Hyung; Kim, Jung Sik

    1994-01-01

    We analyzed the sonograms of 6 cases with uterine synechiae in pregnancy. The diagnosis was based on the clinical and sonographic findings. Previous curret age during the artificial abortion and/or after the spontaneous abortion had been done in 5 cases (83.3%). In all cases, uterine synechia in pregnancy was recognized asintra-amniotic sheet containing hypoechoic central zone and an hyperechoic outer layers. Y-shaped splitting of thehyperechoic outer layers was seen against the uterine wall. The placenta extended along the sheet in 4 cases. Uterine synechiae in pregnancy should be distinguished from amniotic band syndrome by the characteristic snographic findings, and unwarranted abortion of normal fetus should be avoided

    Full Text Available Resumo Os portadores da doença celíaca, uma enteropatia, apresentam intolerância ao glúten e a restrição de alimentos que o contenham mostra-se eficaz na normalização da função intestinal e das manifestações clínicas. O objetivo do presente estudo foi avaliar o efeito da adição de colágeno em pó e em fibra nas características estruturais, tecnológicas e sensoriais de pães sem glúten, elaborados com farinha de arroz. Primeiramente, foram realizadas adições de 2%, 4%, 6% e 8% de colágeno, sob as formas em pó e em fibra, em pães elaborados com farinha de arroz, sendo estes avaliados quanto às suas características tecnológicas: volume específico, firmeza do miolo e cor da crosta e do miolo. O pão que apresentou as melhores características tecnológicas foi caracterizado quanto à sua composição química (proteínas, lipídios, cinzas, umidade e carboidratos, avaliado quanto às perdas decorrentes da cocção e submetido à análise sensorial. As massas cruas dos pães adicionados com o colágeno em fibra, assim como a massa do pão padrão (sem adição de colágeno, foram avaliadas através de reologia e microscopia eletrônica de varredura. A adição de colágeno aos pães elaborados com farinha de arroz não colaborou para a formação de uma rede semelhante à formada pelo glúten. O pão da formulação com 4% de colágeno em fibra apresentou as características tecnológicas mais próximas ao esperado, não diferindo significativamente quanto à composição química, do pão padrão. Por meio da análise sensorial, constatou-se que os pães sem glúten (padrão e com 4% de colágeno em fibra obtiveram aceitação sensorial superior a 75%. Conclui-se, com o estudo, que é possível adicionar colágeno em pães sem glúten, sendo que o pão adicionado de 4% de colágeno em fibra apresentou características mais próximas às do pão padrão testado.

    2008-01-01

    Background and purpose: Uterine carcinosarcoma is an aggressive neoplasm and the benefit of adjuvant radiation therapy (RT) is unclear. This retrospective study analyzes the influence of RT on survival using a large population database. Materials and methods: Data were obtained from the Surveillance, Epidemiology, and End Results (SEER) program of the US National Cancer Institute. Women with uterine carcinosarcoma who underwent primary surgery were eligible. Survival rates and multivariate analyses were performed by standard methods. Results: Of the 2461 women in the analysis, 890 received adjuvant RT. Five-year rates of overall survival were 41.5% and 33.2% (P < 0.001) and uterine-specific survival were 56.0% and 50.8% (P = 0.005), for women receiving RT compared to those who did not. Women with stages I-III disease experienced a benefit in overall survival (HR 0.87, P = 0.03) while women with stage IV disease experienced benefits in overall (HR 0.63, P < 0.001) and uterine-specific survival (HR 0.63, P = 0.004) with RT. Conclusions: RT predicted for improved overall and disease specific survival in women with uterine carcinosarcoma within the SEER database. The benefit in disease specific survival was restricted to stage IV disease. These benefits may indicate a role for adjuvant RT in future prospective trials in the treatment of uterine carcinosarcoma

    During the surgical procedure, endometrial cells can be seeded into the wound edge of the uterine wall, developing into scar endometriosis. Due to the extremely low incidence, estimation of its prevalence is still unavailable. Even rarer might be the scar endometriosis in uterine cavity, to our best knowledge, a situation has not been reported yet. A 37-year-old woman complained of heavier and prolonged menstruation as well as pelvic pain during menses for more than 4 months. An endometrial cyst in diameter of 6 cm in uterine cavity was revealed by transvaginal ultrasound. Her surgical history was significant for 1 caesarean section and 1 abdominal myomectomy through transverse incision of lower uterine segment. Space-occupying lesions in uterine cavity, moderate anemia and scar uterus. The hysteroscopy was performed and a multilocular cyst full of chocolate-like fluid was removed. Pathological examination confirmed endometrial glands in the removed cyst tissue. During the follow-up visits at 1 and 6 months after surgery, the patient denied any special discomfort. Her postoperative transvaginal ultrasound showed an enlarged uterus with no lesion in uterine cavity. To achieve a better surveillance, a 3-year period of follow-up after surgery at a 6-month interval was suggested. Intrauterine endometriosis should be considered in patients of pelvic surgery history with pelvic pain, menstrual disorder, and intrauterine cystic mass.

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

    2010-01-01

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

    Uterine rupture is a preventable condition which has persistently remained in our environment. The aim of this study therefore is to ascertain the incidence of uterine rupture, examine the predisposing factors and maternal and fetal outcome of patients managed of uterine rupture in a tertiary hospital. This descriptive case series was conducted at the department of Obstetrics and Gynaecology, Nnamdi Azikiwe, University Teaching Hospital Nnewi from March 2004 to February 2009. The incidence of uterine rupture was 6.2 per 1000 deliveries. The commonest age range of occurrence was 30-34 years. Uterine rupture occurred predominantly among women of low parity. Previous caesarean section with concurrent use of oxytocics was the commonest risk factor documented.The maternal and perinatal mortality ratio was 94 per 100,000 deliveries and 6 per 1000 births respectively. Surgery was the main stay of treatment and the commonest procedure carried out was uterine repair only. Rupture of the gravid uterus is still a significant cause of maternal mortality and morbidity in our environment. The causes are commonly preventable. The provision of maternal care by skilled personnel, proper antenatal care, update training programmes for health care providers and appropriate legislation on maternal care will significantly reduce the incidence of uterine rupture and improve its prognosis.

  7. The Ultrasound and MRI Findings of Uterine Adenofibroma: A Case Report

    2011-01-01

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

    The most abundant of the collagen protein family, type I collagen is encoded by the COL1A2 gene. The COL1A2 restriction fragment length polymorphisms (RFLPs) EcoRI, RsaI and MspI in samples from several different central-eastern Mediterranean populations were analysed and found to be potentially informative anthropogenetic markers. The objective was to define the genetic variability of COL1A2 in the central-eastern Mediterranean and to shed light on its genetic distribution in human groups over a wide geographic area. PCR-RFLP analysis of EcoRI, RsaI and MspI polymorphisms of the COL1A2 gene was performed on oral swab and blood samples from 308 individuals from the central-eastern Mediterranean Basin. The genetic similarities among these groups and other populations described in the literature were investigated through correspondence analysis. Single-marker data and haplotype frequencies seemed to suggest a genetic homogeneity within the European populations, whereas a certain degree of differentiation was noted for the Egyptians and the Turks. The genetic variability in the central-eastern Mediterranean area is probably a result of the geographical barrier of the Mediterranean Sea, which separated European and African populations over time.

    1986-01-01

    Vaginal suppositories of Adriamycin (ADM, 5 mg), for reducing the capacity for repair from sublethal damage of X-ray-irradiated cells, were prepared using Wipepsol S-55 as the vehicle, and were intravaginally administered to patients with advanced uterine cervical cancer, and their pharmacokinetics and clinical effects were studied. The ADM concentration in the uterine cervical cancer tissues indicated high levels (17 to 566 μg/g), and migration into the cardinal ligament and regional lymph nodes was noted. However, little ADM was detected in serum (0 to 0.14 μg/g), probably because of its molecular weight and excellent tissue absorbance, and no side effects, such as cardiotoxicity and myelosuppression due to consecutive administration were detected. Histologically, the effect obtained when administered alone was limited, administration in combination with radiotherapy being more effective. Accordingly, radiotherapy of advanced uterine cervical cancer with concomitant administration of ADM vaginal suppositories seems to bring about a more powerful antitumoral effect with fewer systemic side effects.

    Highlights: • Change in ADC and contrast enhancement of uterine fibroids following UFE was studied. • ADC of fibroids rises post-UFE. Previous studies assessing this change have conflicting results. • ADC rise post-UFE is associated with degree of loss of contrast enhancement. • ADC measurement using DWI is not yet a proven replacement for GBCA-enhanced MRI. - Abstract: Objective: To determine the change in apparent diffusion coefficient (ADC) of uterine fibroids following uterine fibroid embolisation (UFE), and if the ADC change correlates with either volume loss or degree of contrast enhancement post-UFE. Materials and methods: This study was approved by our institutional review board with waiver of consent. The pelvic MRI examinations, including diffusion-weighted MRI (DWI) using 4 b-values, of 50 consecutive patients prior to and 6 months post-UFE were analyzed. The volume, ADC and amount of enhancement were calculated for each fibroid both pre- and post-UFE. The percent residual enhancement for each fibroid was categorized as either: no (0–1%) residual enhancement or residual (>1%) enhancement. Statistical analysis compared ADC, enhancement and volume for each fibroid pre- and post-UFE using paired t-tests and Pearson correlation coefficients. Results: The mean ADC of all (n = 88) fibroids pre-UFE was 1.30 ± 0.20 × 10{sup −3} mm{sup 2}/s, and increased to 1.68 ± 0.24 × 10{sup −3} mm{sup 2}/s post-UFE (p < 0.0001). Lower pre-UFE ADC correlated with greater ADC change post-UFE (r = −0.50; p < 0.0001). There was no correlation between ADC change and volume change post-UFE (r = 0.07; p = 0.59). However, fibroids with no residual enhancement post-UFE had larger ADC change than those with residual enhancement (p = 0.003). Conclusion: The ADC of fibroids rises post-UFE. ADC change post-UFE is associated with the degree of loss of enhancement and may therefore be valuable in predicting response to treatment in pre-procedural counseling.

    Full Text Available A matriz extracelular no carcinoma epidermóide da cavidade oral sofre modificações qualitativas e quantitativas durante a sua progressão. Estas alterações parecem possibilitar os processos de invasão e metástase que caracterizam as neoplasias malignas e são mais evidentes na interface tumor-hospedeiro. No nosso estudo, 23 biópsias incisionais de carcinomas epidermóides de diversas localizações da cavidade oral foram classificadas segundo o sistema de graduação histológica preconizado por Anneroth et al.¹ (1987. Foram utilizadas as colorações pela H. E. e a do tipo picrosirius, específica para colágeno. A expressão imuno-histoquímica do colágeno tipo I foi analisada em lesões com diferentes escores histológicos de malignidade. Pôde-se concluir que o colágeno apresenta diferentes padrões morfológicos, histoquímicos e imuno-histoquímicos em lesões com altos e baixos escores de malignidade.

    Hereditary arthro-ophtalmopathy (AO) or Stickler Syndrome (MIM No. 10830) is a dominantly inherited disorder characterized by vitro-retinal degeneration and other connective tissue disturbances. Mutations in the COL2A1 gene, coding for type II collagen chains, have been described in a few patients. The wide spectrum of clinical manifestations is presumably due to genetic heterogeneity, since only about 50% of the Stickler families so far studied show cosegregation of the disease with the COL2A1 locus. We have investigated a large pedigree (19 individuals of whom 9 are affected) in which severe myopia with vitro-retinal degeneration consegregated with joint laxity, recurrent inguinal hernias, and degenerative changes of the hip and the knee. The 3{prime} end COL2A1 VNTR polymorphism was utilized for linkage analysis. In order to get the maximum informativity, we have analyzed the allelic microheterogeneity of this VNTR, due to the repeat sequence variation, by means of a single strand polymorphism. Mendelian inheritance of the different single strands was observed as expected. Discordance of segregation between the disease and the COL2A1 locus was thus established inequivocally in this family.

  15. Maternal uterine artery VEGF gene therapy for treatment of intrauterine growth restriction.

    2017-11-01

    Intrauterine growth restriction (IUGR) is a serious pregnancy complication affecting approximately 8% of all pregnancies. The aetiology is believed to be insufficient maternal uteroplacental perfusion which prevents adequate nutrient and oxygen availability for the fetus. There is no treatment that can improve uteroplacental perfusion and thereby increase fetal growth in the uterus. Maternal uterine artery gene therapy presents a promising treatment strategy for IUGR, with the use of adenoviral vectors encoding for proteins such as Vascular Endothelial Growth Factor (VEGF) demonstrating improvements in fetal growth and neonatal outcome in preclinical studies. Mechanistically, maternal VEGF gene therapy delivered to the uterine arteries increases uterine blood flow and enhances vascular relaxation short term, while reducing vascular contractility long term. It also leads to vascular remodeling with increased endothelial cell proliferation in the perivascular adventitia of uterine arteries. Safety assessments suggest no vector spread to the fetus and no adverse risk to the mother or fetus; a clinical trial is in development. This article assesses research into VEGF maternal uterine artery directed gene therapy for IUGR, investigating the use of transgenes and vectors, their route of administration in obstetrics, and the steps that will be needed to take this treatment modality into the clinic.

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

    In the past, total uterine prolapse in the sow has been regarded as a grave condition because manipulative reposition through the vulva and vagina is extremely difficult, if not impossible, and amputation is merely a salvage procedure with a mortality rate approaching 100 percent. Laparotomy as a means of facilitating reduction of the prolapse in the sow appears to have been overlooked although it is a standard procedure in dogs and cats. This report describes a case of uterine prolapse in a sow successfully treated by laparotomy.

    Objective: To investigate the efficiency and safety of transcatheter uterine artery embolization (TUAE) as well as the pathological changes and it's significance after embolization. Methods: 44 cases of uterine fibroids were treated by TUAE using lipiodol-pingyangmycin emulsion (LPE) and Gelfoam sponge particle. Seven of 44 cases underwent hysterectomy or myomectomy from 1 to 6 weeks after TUAE. The specimens were studied to observe pathological changes of fibroids and myometrium. 37 of 44 patients were followed up for 1 to 6 months to observe the changes of fibroid size and uterine volume. The changes of ovarian function and myometrium after TUAE were found out by observation on mensis, test of ovarian hormone, premenstrual diagnostic curettage and pathology of the resected specimens. Results: Total improvement of symptoms occurred in 91.9%(34/37), including control of menorrhagia in 91.4%(32/35), disappearance of lumbago and lower abdominal pain in 85.3% (29/34), relief of frequency and urgency of micturition in 50.0%(7/14). Average decrease of fibroid and uterine volume at 6 months after TUAE was 61.3% and 50.6% respectively. No amenorrhea happened. Premenstrual diagnostic curettage showed secretory endometrium. There was no significant difference in ovarian hormone level before and after embolization. Pathological study showed that lipiodol was found to deposit in fibroids and was no seen in myometrium. Spotty necrosis 2 weeks occurred in fibroid and extensive patchy necrosis 3 weeks after embolization. The necrotic area became larger with elapse of time postoperative. Necrosis was not seen in myometrium. Conclusion: TUAE is a new, and effective procedure for uterine fibroid and LPE as an embolizing agent is safe without damage on myometrium

    Objective: To find the accuracy of uterine artery diastolic notching during the second trimester of pregnancy in predicting pre-eclampsia in primigravida patients. Study Design: Descriptive cross sectional study. Place and Duration of Study: Armed Forces Institute of Radiology and Imaging (AFIRI) Rawalpindi; six months duration from 30 Nov 2012 to 31 May 2013. Material and Methods: This study included 199 primigravida women with singleton pregnancy having diastolic notch in uterine arteries between 20 to 23 weeks of gestation. All patients were examined by both grey scale and doppler ultrasonography. Uterine arteries were evaluated with doppler near the point where they crossed the external iliac arteries. The patient was included in study if the presence of diastolic notch was demonstrated. Clinical follow up in gynae and obs department continued throughout the pregnancy to see if they developed preeclampsia. The data were recorded on a previously prepared proforma and analyzed with SPSS 21. Results: The accuracy of uterine artery doppler ultrasound in identifying women who later developed preeclampsia was 48.24 percent. The frequency of pre-eclampsia with bilateral notch was significantly high in the primigravid of younger age as compare to the primigravid of the older group (p=0.001). The difference in frequency of developing pre-eclampsia with bilateral notch when compared among 20 to 21 week gestational age and 22 to 23 weeks gestational age was statistically insignificant. Conclusion: Uterine artery diastolic notching between 20 and 23 weeks of gestation is an important risk factor for developing pre-eclampsia. This doppler parameter should, therefore, be included in the risk evaluation for gestational hypertension. (author)

    High-intensity focused ultrasound (HIFU) is a highly precise medical procedure used locally to heat and destroy diseased tissue through ablation. This study intended to review HIFU in uterine fibroid therapy, to evaluate the role of HIFU in the therapy of leiomyomas as well as to review the actual clinical activities in this field including efficacy and safety measures beside the published clinical literature. An inclusive literature review was carried out in order to review the scientific foundation, and how it resulted in the development of extracorporeal distinct devices. Studies addressing HIFU in leiomyomas were identified from a search of the Internet scientific databases. The analysis of literature was limited to journal articles written in English and published between 2000 and 2013. In current gynecologic oncology, HIFU is used clinically in the treatment of leiomyomas. Clinical research on HIFU therapy for leiomyomas began in the 1990s, and the majority of patients with leiomyomas were treated predominantly with HIFUNIT 9000 and prototype single focus ultrasound devices. HIFU is a non-invasive and highly effective standard treatment with a large indication range for all sizes of leiomyomas, associated with high efficacy, low operative morbidity and no systemic side effects. Uterine fibroid treatment using HIFU was effective and safe in treating symptomatic uterine fibroids. Few studies are available in the literature regarding uterine artery embolization (UAE). HIFU provides an excellent option to treat uterine fibroids

    Full Text Available Neonatal or infantile uterine prolapse is a quite rare condition and is usually managed with conservative treatment. There is no standard surgical treatment for infantile uterine prolapse, and to the best of our knowledge, only 2 out of 30 patients suffering from it have been reported to undergo surgical repair in English literature since 1961. We here report the first successful case of laparoscopic repair for uterine prolapse in an infant. The patient was a 2-month old girl who had sacral myelomeningocele and Chiari type 2 malformation. She had undergone closure of myelomeningocele and ventriculoperitoneal shunting within 6 weeks after birth. At 7 weeks of age, the rectum and the uterus prolapsed, and the prolapse gradually deteriorated. Conservative treatments including repeated digital reduction, use of ointment and glycerin enema, and placement of a Foley catheter into the vagina were not effective. At the age of 100 days, she underwent laparoscopic hysteropexy and rectopexy. Three ports were placed on the umbilicus and the bilateral abdomen, and the bilateral mesovaria were sutured to the anterior abdominal wall to improve the visualization of the pelvis. The rectum and the uterine body were directly sutured to the sacral promontory with 2 non-absorbable braided sutures each, not using mesh prosthesis. The postoperative course was uneventful and neither uterine nor rectal prolapse has recurred for 2.5 years. We plan to follow up the patient for a long period since the long-term prognosis is not known.

    This case report presents a clinical pregnancy after ulipristal acetate (UA) to decrease uterine fibroid size. A 37-year-old patient, gravida 1, abortus 1, with uterine fibroids was treated with 5 mg of UA daily for 13 weeks starting eight months after a multiple laparotomic myomectomy. Fibroid shrinkage and restoration of the morphology of endometrial cavity were evaluated in order to allow a subsequent pregnancy. A decrease of the uterine fibroids and a normal morphology of the endometrial cavity were noted by transvaginal ultrasound after treatment. An endometrial biopsy excluded histologic endometrial changes. Three months after the end of UA the patient reported amenorrhea for 5 weeks and a clinical pregnancy was confirmed with transvaginal ultrasound. She underwent a subsequent uneventful pregnancy. Thus, the spontaneous pregnancy after UA to reduce fibroid size may support the potential clinical utility of this selective progesterone receptor modulator in the management of women with pregnancy desire and uterine fibroids after a prior myomectomy. Patients who refuse a new surgical procedure and/or those who are going to undergo assisted reproductive techniques would benefit from UA. It effectively shrinks fibroids, avoids risks of a new surgical procedure, and allows an immediate attempt at conception after the end of treatment.

    Peroxidase activity in the uterine luminal fluid of mice treated with diethylstilbestrol was measured by the guaiacol assay and also by the formation of 3H2O from [2-3H]estradiol. In the radiometric assay, the generation of 3H2O and 3H-labeled water-soluble products was dependent on H2O2 (25 to 100 microM), with higher concentrations being inhibitory. Tyrosine or 2,4-dichlorophenol strongly enhanced the reaction catalyzed either by the luminal fluid peroxidase or the enzyme in the CaCl2 extract of the uterus, but decreased the formation of 3H2O from [2-3H]estradiol by lactoperoxidase in the presence of H2O2 (80 microM). NADPH, ascorbate, and cytochrome c inhibited both luminal fluid and uterine tissue peroxidase activity to the same extent, while superoxide dismutase showed a marginal activating effect. Lactoferrin, a major protein component of uterine luminal fluid, was shown not to contribute to its peroxidative activity, and such an effect by prostaglandin synthase was also ruled out. However, it was not possible to exclude eosinophil peroxidase, brought to the uterus after estrogen stimulation, as being the source of peroxidase activity in uterine luminal fluid

    Interstitial pregnancy is defined as any gestation that develops in the uterine portion of the fallopian tubes lateral to the round ligament. Interstitial pregnancies account for 2-4% of all ectopic pregnancies and have been reported to have an associated 2% to 2.5% maternal mortality rate. The traditional treatment for interstitial pregnancy using surgical cornual resection may cause infertility or uterine rupture in subsequent pregnancies. Recently, the early identification of intact interstitial pregnancy has been made possible in many cases with high resolution transvaginal ultrasound as well as more sensitive assays for betahuman chorionic gonadotropin (β-hCG). The treatment includes: hysteroscopic transcervical currettage, local and systemic methotrexate (MTX) therapy and prostaglandin or potassium chloride injection of the ectopic mass under sonographic guidance. We describe a case of successful treatment of interstitial pregnancy using uterine artery embolization, after failure of methotrexate treatment

    Three experiments were conducted on the metabolism of stallion sperm. In experiment 1, whole and washed sperm were incubated under aerobic and anaerobic enviroments and analyzed before and after controlled incubation for motility, pH, lactic acid, glucose, fructose, and O2 comsumption. In experiment 2, whole and washed sperm were incubated aerobically and anaerobically with and without uterine tubal fluids. Experiment 3 was the same as experiment 2, except added substrates of glucose and lactic acid were studied. The same examinations were made in experiments 2 and 3 as for experiment 1. Motility decreased significantly during incubation for all treatments, with the greatest decrease occurring for whole semen where only trace amounts of substrate (fructose) were present. Exogenous glucose plus uterine tubal fluid maintained sperm motility better than did added lactate. However, sperm respiration rates were highest when exogenous lactate was the only substrate in the incubation medium. The mean pH values for gel-free stallion semen at the start of controlled aerobic and anaerobic incubation were 7.08 and 7.34. Lactic acid accummulation for 1 hour increased from 0.05 mg to 0.09 mg/10(9) sperm when uterine tubal fluid was added to the incubation medium. Washed spermatozoa incubated in 0.03 M glucose plus uterine tubal fluid utilized less glucose than did sperm incubated in the glucose medium. These results, along with the increased oxygen utilization (ZO2) values produced by adding uterine tubal fluid to the incubation mediums, might indicate utilization of a uterine tubal substrate. Added uterine tubal fluid resulted in increased ZO2 values (expressed in mul of O2 utilized by 10(8) sperm in 1 hour at 37 C) for whole semen from 10.45 to 12.63. Washed spermatozoa also respired at a significantly greater rate than whole sperm. Respiration rates were greater for sperm incubated with 0.01 M lactic acid than for any other substrate or experiment.

    2013-01-01

    The gynecologic sequelae due to deficient uterine scar healing after cesarean section are only recently being identified and described. These include conditions such as abnormal bleeding, pelvic pain, infertility, and cesarean scar ectopic pregnancy, as well as a potentially higher risk of complications and difficulties during gynecologic procedures such as uterine evacuation, hysterectomy, endometrial ablation, and insertion of an intrauterine device. The proposed mechanism of abnormal uterine bleeding is a pouch or "isthmocele" in the lower uterine segment that causes delayed menstrual bleeding. The prevalence of symptomatic or clinically relevant cesarean scar defects (CSDs) ranges from 19.4% to 88%. Possible risk factors for CSD include number of cesarean sections, uterine position, labor before cesarean section, and surgical technique used to close the uterine incision. There are no accepted guidelines for the diagnostic criteria of CSD. We propose that a CSD be defined on transvaginal ultrasound or saline infusion sonohysterography as a triangular hypoechoic defect in the myometrium at the site of the previous hysterotomy. We also propose a classification system to aid in standardized classification for future research. Surgical techniques for repair of CSD include laparoscopic excision, resectoscopic treatment, vaginal revision, and endometrial ablation. Copyright © 2013 AAGL. Published by Elsevier Inc.

    Objective: To evaluate the clinical outcomes of bilateral uterine artery chemoembolization (UACE) followed by uterine dilation and curettage in treating cesarean scar pregnancy. Methods: A total of 104 patients with cesarean scar pregnancy, admitted to hospital during the period from Jan. 2005 to Jan. 2009, were enrolled in the study. The patients were divided into group A (control group, n=49) and group B (study group, n=55). Patients in group A received uterine dilation and curettage only, and patients in group B received additional UACE, which was performed 24-72 hours before uterine dilation and curettage was carried out. The blood loss during the operation, the time for β-human chorionic gonadotrophin (β-hCG) level going down to normal, the success rate of operation, the hospitalization days, the occurrence of complications and the menstrual situation after operation were documented. The results were analyzed and compared between the two groups. Results: In group A, 4 patients had to receive hysterectomy due to massive hemorrhage or inadequate curettage. None of the patients in group B needed to have a hysterectomy. the technical success rates of curettage for group A and group B were 91.84% and 100%, respectively. The mean blood loss in group B was (54.36±38.09) ml, which was significantly lower than that of (54.36±38.09) ml in group A (P 0.05], while between those patients who had pregnancy time > 10 weeks, the blood loss in group B was much less than that of group A [(101.33±39.43) ml vs. (457.14±97.59) ml, P 0.05]. The difference in hospitalization days between the patients with pregnancy time ≤ 10 weeks in two groups [(11.21±3.24) days vs. (12.68±34.56) days] was not significant (P>0.05). But for patients with pregnancy time > 10 weeks, the hospitalization days of group B was significantly shorter than that of group A (13.46±4.87 days vs. 19.34±5.72 days, P<0.01), Except for 4 patients who had received hysterectomy, all patients regained

    Uterine gas gangrene caused by Clostridium perfringens is a serious, often life-threatening infection that is rarely encountered in the practice of gynecologic oncology. However, the hypoxic nature of gynecologic cancers due to necrosis and/or prior radiation therapy creates a microenvironment optimal for proliferation of anaerobic bacteria such as the Clostridium species. Early recognition and aggressive treatment with IV antibiotics and surgical debridement remain the cornerstones of management in order to decrease morbidity and mortality. Here we present the case of a 52 year-old woman with a remote history of cervical cancer who was previously treated at our institution with primary chemotherapy and radiation and was then admitted decades later with Clostridium perfringens bacteremia and CT evidence of intrauterine abscess. The patient received a prolonged course of IV antibiotic therapy and subsequently underwent definitive surgical management with a total abdominal hysterectomy, bilateral salpingo-oophorectomy, small bowel resection with anastomosis for a utero-ileal fistula identified intraoperatively. Pathology from the uterine specimen demonstrated a primary poorly differentiated uterine adenocarcinoma. The patient recovered fully from her Clostridium perfringens infection and was discharged from the hospital shortly after surgical intervention.

    Full Text Available Synchronous gynecological cancers are rarely described. Those cases account for approximately up to 6% of female genital tract malignancies. The presence of synchronous endometrial adenocarcinoma and gynecological tract neoplasia is rare – the most commonly described is synchronous adenocarcinoma and endometrial ovarian cancer (accounting for 15-20% of ovarian neoplasia and 5% of endometrial cancers. Concomitant uterine carcinosarcoma and ovarian cancer, or endometrial adenocarcinoma are extremely rare. Up till now, only 3 cases of synchronous adenocarcinoma and leiomyosarcoma were described. In the present study a case of 60-year-old woman diagnosed with synchronous endometrial adenocarcinoma and leiomyosarcoma uteri is described. As the preoperative evaluation revealed endometrial adenocarcinoma G2 with intermediate-risk of lymph node metastasis and synchronous leiomyosarcoma G3, total hysterectomy with bilateral salpingo-oophorectomy and systemic lymphadenectomy was performed showing no lymphatic involvement. In the postoperative evaluation the patient was qualified to adenocarcinoma low recurrence-risk group (adenocarcinoma G1 with no LVSI, FIGO IA – no further radiotherapy was required. However, as synchronous leiomyosarcoma G3 was diagnosed, we decided to refer the patient for adjuvant chemotherapy. Contemporary recommendation on the diagnosis and treatment of uterine carcinomas, especially uterine leiomyosarcomas, is also described in this paper. The presented case showed that diagnosis and treatment of women with uterine tumors should be individualized as in the same case an extremely rare cancer type can be present which, consequently, changes the treatment regimen and prognosis.

    Objective: To discuss the therapeutic effect of uterine arterial embolization in treating adenomyosis. Methods: Uterine arterial embolization was performed in 80 patients with adenomyosis. The patients were followed up for 3, 6, 12 and 24 months after the operation. After the treatment the degree of dysmenorrhea, the menstrual flow and the uterine volume were observed and were compared with those before the treatment. Results: After uterine arterial embolization the clinical symptoms were relieved in all 80 patients. The menstrual flow was markedly decreased, the anemia was obviously improved and the uterine volume was significantly reduced, while the ovary functioning was not apparently affected. The symptom of dysmenorrhea completely disappeared one month after the therapy in 76 cases and four months after the therapy in the remaining 4 cases. Conclusion: Uterine arterial embolization is a mini-invasive and safe therapy with remarkable therapeutic results and few side-effects. Therefore, this treatment can significantly improve the patient's living quality. (authors)

    Total uterine blood flow was measured with a tritiated water (TOH) diffusion method and with radioactive microspheres in six, conscious, pregnant ewes. With continuous infusion of TOH, equilibrium between the TOH concentration in utero-ovarian venous blood and arterial blood was attained within 50 min of the start of the infusion. The concentration of TOH in uterine and foetal tissue and in foetal blood water was the same as that in uterine venous water by 40 min; at this time, the concentration of TOH in the water of amniotic and allantoic fluids was 96% of that in uterine venous blood water. Estimates of total uterine blood flow obtained using TOH were highly correlated with those obtained with microspheres and the corresponding mean flow values obtained with the two techniques did not significantly differ. The percentage of the total uterine blood flow passing through arteriovenous anastomoses ranged from 1.4 to 3.3%

    To assess the prevalence of congenital uterine anomalies, including arcuate uterus, and their effect on reproductive outcome in subfertile women undergoing assisted reproduction. Consecutive women referred for subfertility between May 2009 and November 2015 who underwent assisted reproduction were included in the study. As part of the initial assessment, each woman underwent three-dimensional transvaginal sonography. Uterine morphology was classified using the modified American Fertility Society (AFS) classification of congenital uterine anomalies proposed by Salim et al. If the external contour of the uterus was uniformly convex or had an indentation of Reproductive outcomes, including live birth, clinical pregnancy and preterm birth, were compared between women with a normal uterus and those with a congenital uterine anomaly. Subgroup analysis by type of uterine morphology and logistic regression analysis adjusted for age, body mass index, levels of anti-Müllerian hormone, antral follicle count and number and day of embryo transfer were performed. A total of 2375 women were included in the study, of whom 1943 (81.8%) had a normal uterus and 432 (18.2%) had a congenital uterine anomaly. The most common anomalies were arcuate (n = 387 (16.3%)) and subseptate (n = 16 (0.7%)) uterus. The rate of live birth was similar between women with a uterine anomaly and those with a normal uterus (35% vs 37%; P = 0.47). The rates of clinical pregnancy, mode of delivery and sex of the newborn were also similar between the two groups. Preterm birth before 37 weeks' gestation was more common in women with uterine anomalies than in controls (22% vs 14%, respectively; P = 0.03). Subgroup analysis by type of anomaly showed no difference in the incidence of live birth and clinical pregnancy for women with an arcuate uterus, but indicated worse pregnancy outcome in women with other major anomalies (P = 0.042 and 0.048, respectively). Congenital uterine anomalies as a whole, when

    Dysregulated cyclin-dependent kinases (CDKs) are considered a potential target for cancer therapy. Flavopiridol is a potent CDK inhibitor. In this study, the antiproliferative effect of the flavonoid compound flavopiridol and its mechanism in human uterine leiomyoma cells were investigated. The present study focused on the effect of flavopiridol in cell proliferation and cell cycle progression in primary cultured human uterine leiomyoma cells. Cell viability and cell proliferation assays were conducted. Flow cytometry was performed to determine the effect of flavopiridol on cell cycle. The expression of cell cycle regulatory-related proteins was evaluated by Western blotting. Cell viability and proliferation of uterine leiomyoma cells were significantly reduced by flavopiridol treatment in a dose-dependent manner. Flow cytometry results showed that flavopiridol induced G1 phase arrest. Flavopiridol-induced growth inhibition in uterine leiomyoma cells was associated with increased expression of p21cip/wafl and p27kip1 in a dose-dependent manner. Downregulation of CDK2/4 and Cyclin A with a concomitant increase in dephosphorylation of retinoblastoma was observed. This study demonstrates that flavopiridol inhibits cell proliferation by initiating G1 cell cycle arrest in human uterine leiomyoma. We also found that flavopiridol is effective in inhibiting xenografted human uterine leiomyoma growth. These results indicate that flavopiridol could prove to be a promising chemopreventive and therapeutic agent for human uterine leiomyoma. PMID:24572052

    2017-03-01

    Full Text Available Introduction: Uterine leiomyomas arise from the proliferation of smooth muscle cells. ACE gene encodes a convertase enzyme mainly secreted in vascular endothelial cells which is involved in the renin–angiotensin system and blood pressure controlling. This gene has an insertion/deletion (I/D polymorphism correlates to serum and tissue ACE levels. The aim of this study is to elucidate the relationship between ACE gene variation and the development of myom. Methods: The samples of 55 uterine leiomyoma patients and 78 healthy women were studied. After obtaining informed consent, blood samples were collected and DNA extraction was performed by Salting-out method. Genotyping was performed using PCR reaction. The amplified products were two bands of 190 and 490 bp, which represents D allele and I allele, respectively. Statistical analysis was done using Chi-square test. Results: The D allele frequency was 0.55 in the patient group and 0.51 in the control group. The I allele frequencies in the two groups were 0.45 and 0.49, respectively. The results showed that taking the II genotype into account as reference genotype; homozygous DD individuals were at increased risk of uterine myoma (Odds ratio: 1.37. However, heterozygous ID showed a similar risk with the II genotype as the reference group. Conclusion: High blood pressure is significantly associated with uterine fibroids. It has been shown that atherosclerotic damage of uterine blood vessels and the inflammatory process caused by it may play an important role in the development of uterine myoma. This study indicates a positive relationship between the ACE (I/D polymorphism and the risk of uterine myoma. This finding is evidence of the important role of the renin–angiotensin system in the pathogenesis of myoma

    Full Text Available Uterine leiomyosarcoma (Ut-LMS develops more frequently in the myometrium of the uterine body than in the uterine cervix. Although the development of gynecological tumors is often correlated with the secretion of female hormones that of Ut-LMS does not, and its risk factor(s remain unknown. Importantly, a diagnostic biomarker that can distinguish malignant tumor Ut-LMS from benign tumor leiomyoma (LMA, has yet to be established. Therefore, the risk factor(s associated with Ut-LMS need to be examined in order to establish a diagnosis and clinical treatment method. Mice with a homozygous deficiency for the proteasome b-ring subunit, low-molecular mass polypeptide (LMP2/b1i spontaneously develop Ut-LMS, with a disease prevalence of ~40% by 14 months of age. In recent studies, we showed that LMP2/b1i expression was absent in human Ut-LMS, but present in other human uterine mesenchymal tumors including uterine LMA. Moreover, LMP2/b1i is also known to negatively regulate human Ut-LMS tumorigenesis. Additional experiments furthermore revealed the differential expression of cyclin E and calponin h1 in human uterine mesenchymal tumors. Therefore, LMP2/b1i is a potential diagnostic biomarker when combined with the candidate molecules, cyclin E and calponin h1 for human Ut-LMS, and may be a targeted molecule for a new therapeutic approach.---------------------------------------------Cite this article as: Hayashi T, Horiuchi A Aburatani H, Ishiko O, Yaegashi N, Kanai Y, Zharhary D, Tonegawa S, Konishi I.

    A deep vein thrombosis was rarely associated with uterine myomas. Hereby, it is presented the case of a 40-year-old woman in which the clinical manifestation of the deep vein thrombosis revealed the further diagnosis of a large uterine myoma. The diagnosis, management and clinical outcome of the patient are emphasized and discussed. The management of a patient with a uterine myoma and deep vein thrombosis is challenging and implies a multidisciplinary team.

    Full Text Available Aim - immunohistochemical detection of structural features of the uterine tubes of fetuses with signs of intrauterine infection.Methods: anthropometric, macroscopic, organometric, histological, immunohistochemical, statistical.Object of research - the uterine tubes of antenatal dead fetuses. The control group consisted of 25 fetuses of healthy mothers; the comparison group is 15 fetuses with signs of intrauterine infection. Fetal infection confirmed by laboratory methods; the presence of TORCH infections, cytomegalovirus, herpes infection and chlamydial infection is determined.Results: indicators of weight and body length of the fetus of the comparison group were significantly reduced. Unidirectional changes are established in the definition of the mass and the length of the uterine tubes of fetuses with signs of intrauterine infection. Massive growth of connective tissue in the mucosa, the mucous membrane and muscle membrane of wall of the uterine tube of fetus in the comparison group is shown by histological methods. Violation of collagen formation in the connective tissue in the uterine tubes of fetuses with signs of intrauterine infection is found by immunohistochemistry method.Conclusions: The reduction of anthropometric and organometric indicators in fetuses of comparison group is shown. Sclerosis and atrophy, as well as violations of collagen-synthesizing function are predominated in the main structural components of the wall of the uterine tube of fetuses in the comparison group. The revealed changes in the future ontogenesis may lead to the development of primary infertility

    Recently, a genome-wide association study has indicated associations between single nucleotide polymorphisms in the Collagen Type XXVII Alpha 1 gene (COL27A1) and Tourette syndrome in several ethnic populations. To clarify the global relevance of the previously identified SNPs in the development of Tourette syndrome, the associations between polymorphisms in COL27A1 and Tourette syndrome were assessed in Chinese trios. PCR-directed sequencing was used to evaluate the genetic contributions of three SNPs in COL27A1(rs4979356, rs4979357 and rs7868992) using haplotype relative risk (HRR) and transmission disequilibrium tests (TDT) with a total of 260 Tourette syndrome trios. The family-based association was significant between Tourette syndrome and rs4979356 (TDT: χ2 = 4.804, P = 0.033; HRR = 1.75, P = 0.002; HHRR = 1.32, P = 0.027), and transmission disequilibrium was suspected for rs4979357 (TDT: χ2 = 3.969, P = 0.053; HRR = 1.84, P = 0.001; HHRR = 1.29, P = 0.044). No statistically significant allele transfer was found for rs7868992 (TDT: χ2 = 2.177, P = 0.158). Although the TDT results did not remain significant after applying the conservative Bonferroni correction (p = 0.005), the significant positive HRR analysis confirmed the possibility of showing transmission disequilibrium, which provides evidence for an involvement of COL27A1in the development of TS. However, these results need to be verified with larger datasets from different populations.

    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. © The Author 2014.

    Specimens of endometrial biopsies can sometimes present with an artifact within blood, composed of optically clear vacuoles mimicking adipose tissue, pseudolipomatosis. This artifact can be mistaken for adipose tissue and lead to an overdiagnosis of uterine perforation. We describe the case of pseudolipomatosis seen within the evacuated products of conception from a missed abortion. Areas of vacuolization in the blood clot mimicked adipose tissue. However, the vacuoles varied in size and did not contain adipocytes. Familiarity with this artifact will lead to avoidance of overdiagnosis of adipose tissue and uterine perforation in curettage specimens.

    Transvaginal ultrasound is the first-line imaging test for the evaluation of abnormal uterine bleeding in both premenopausal and postmenopausal women. Transvaginal ultrasound can be used to diagnose structural causes of abnormal bleeding such as polyps, adenomyosis, leiomyomas, hyperplasia, and malignancy, and can also be beneficial in making the diagnosis of ovulatory dysfunction. Traditional 2-dimensional imaging is often enhanced by the addition of 3-dimension imaging with coronal reconstruction and saline infusion sonohysterography. In this article we discuss specific ultrasound findings and technical considerations useful in the diagnosis of abnormal uterine bleeding.

    PurposeWe evaluated the location of porous gelatin particles (GP; Gelpart; Nippon Kayaku/Astellas, Tokyo, Japan) within the arterial vasculature and their acute effects on uterine necrosis and inflammation after uterine artery embolization (UAE) in swine.Materials and MethodsAdult nonpregnant pigs (n = 6) were allocated to either 1- (n = 3) or 2-mm GP (n = 3). Superselective and bilateral embolization of the uterine arteries was performed. All animals were killed 1 week after UAE. Macroscopic and microscopic findings, including the level of arterial occlusion and their effect on uterine necrosis and inflammation, were analyzed.ResultsAll UAE procedures were completed without severe complications. The macroscopic necrosis was seen in two animals in the 2-mm group with an extent of <50%. The location of the occluded arteries did not differ significantly between groups. The median diameters of the occluded arteries were 449 μm (95% confidence interval [CI] 417-538 μm) in the 1-mm GP group and 484 μm (95% CI 370-560 μm) in the 2-mm GP group. As for microscopic necrosis, no statistically significant difference was observed. The qualitative inflammatory reaction was significantly greater in the 2-mm GP group than in the 1-mm group (p < 0.001).ConclusionsBoth 1- and 2-mm GP occluded the arteries relevant to the target diameter for UAE in porcine uterus, presumably due to the plastic deformity. Both sizes of GP were associated with limited areas of necrosis; however, evaluation of inflammatory reaction was preliminary. Further study with adequate evaluation of inflammatory reactions is suggested.

    Full Text Available Retrospective data of treatment results of 109 patients with rarely observed stage II uterine cancer, admitted to N.N. Blokhin Russian Cancer Research Center from 1980 to 2000 is analyzed. Correlation of overall 5-year survival rates of stage IIA and IIB uterine can- cer patients with a number of tumor morphologic features is studied. The influence of some non-elucidated morphologic features of stage IIA and IIB uterine cancer such as the degree of cellular anaplasia, the depth of tumor invasion into the uterine neck, lymho- vascular invasion into the myometrium and uterine neck, microscopic vessels density in the area of the most extensive invasion, the presence of necrotic areas in the tumor tissue on long-term treatment results are analyzed.

  9. Urban metabolism and river systems: an historical perspective – Paris and the Seine, 1790–1970

    Full Text Available The aim of this paper is to analyse metabolic interaction between Paris and the Seine during the industrial era, 1790–1970, a period marked by strong population growth, technological changes, and the absence of specific legislation on environmental issues. The viewpoint focuses on exchanges of waters and wastes between city and river, quantifying them and tracing their evolution in the light of the strategies implemented by the stakeholders in charge. The study combines industrial ecology, local history and the history of technology. From 1790 to 1850, waste matters, and especially excreta, were considered as raw materials, not refuse: they generated real profits. The removal of human excreta aimed not only at improving urban hygiene, but at producing the fertilizers needed in rural areas. Discharging them into the river was out of the question. But after the 1860s, several factors upset this exploitation, notably domestic water supply: night soil became more and more liquid, difficult to handle and to turn into fertilizer; once utilised, the water had to be removed from the house; at the same time, the sewerage system developed and had negative impacts on the river. Even so, Parisian engineers continued to process sewage using techniques that would not only ensure hygiene but also conciliate economic and agricultural interests: combined sewerage system and sewage farms. Both of these early periods are thus noteworthy for a relative limitation of the river's deterioration by urban wastes. Not until the 1920s, when domestic water supply had become the standard and excreta came to be considered as worthless waste, was the principle of valorisation abandoned. This led to important and long-lasting pollution of the Seine (despite the construction of a treatment plant, aggravating the industrial pollution that had been in evidence since the 1840s. Analysing the priorities that led to the adoption of one principle or another in matters of urban

    Uterine leiomyomas are the most common benign tumors of the female urogenital tract. Beside the classic surgical treatment options the minimal-invasive embolization therapy of the leiomyomas increasingly gains importance world-wide. Technique, complications, and results of uterine leiomyoma embolization will be presented. After careful evaluation of indications for embolization the procedure is mostly performed under conscious sedation. A single-sided femoral access route together with cross-over technique generally allows for a flow-directed embolization via both uterine arteries. After embolizing the vessels supplying the tumor, the uterine arteries should be still patent. The success rate of embolization of uterine leiomyomas ranges between 85 and 100%, whereas a reduction in size of the tumors in 42 to 83% and a relief of symptoms in up to 96% can be achieved. The total complication rate is about 10% with mainly ''minor complications''. Worldwide only three deaths following embolization of uterine leiomyomas were reported. The high technical and clinical success rate together with a low complication rate make the embolization of uterine leiomyomas a minimally-invasive alternative to the classic treatment. As long term results are not available indication to embolization of uterine leiomyomas must be carefully established in consensus with gynecologists. (orig.)

    Endometrial biopsies are undertaken in premenopausal women with abnormal uterine bleeding but the risk of endometrial cancer or atypical hyperplasia is unclear. To conduct a systematic literature review to establish the risk of endometrial cancer and atypical hyperplasia in premenopausal women with abnormal uterine bleeding. Search of PubMed, Embase and the Cochrane Library from database inception to August 2015. Studies reporting rates of endometrial cancer and/or atypical hyperplasia in women with premenopausal abnormal uterine bleeding. Data were independently extracted by two reviewers and cross-checked. For each outcome, the risk and a 95% CI were estimated using logistic regression with robust standard errors to account for clustering by study. Sixty-five articles contributed to the analysis. Risk of endometrial cancer was 0.33% (95% CI 0.23-0.48%, n = 29 059; 97 cases) and risk of endometrial cancer or atypical hyperplasia was 1.31% (95% CI 0.96-1.80, n = 15 772; 207 cases). Risk of endometrial cancer was lower in women with heavy menstrual bleeding (HMB) (0.11%, 95% CI 0.04-0.32%, n = 8352; 9 cases) compared with inter-menstrual bleeding (IMB) (0.52%, 95% CI 0.23-1.16%, n = 3109; 14 cases). Of five studies reporting the rate of atypical hyperplasia in women with HMB, none identified any cases. The risk of endometrial cancer or atypical hyperplasia in premenopausal women with abnormal uterine bleeding is low. Premenopausal women with abnormal uterine bleeding should first undergo conventional medical management. Where this fails, the presence of IMB and older age may be indicators for further investigation. Further research into the risks associated with age and the cumulative risk of co-morbidities is needed. Contrary to practice, premenopausal women with heavy periods or inter-menstrual bleeding rarely require biopsy. © 2016 The Authors BJOG An International Journal of Obstetrics and Gynaecology published by John Wiley & Sons Ltd on behalf of Royal

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

    To evaluate whether xenografts derived from hysterectomized patients would implant successfully and lead to uterine leiomyoma in Wistar rats. This experimental study examined six female Wistar rats implanted with uterine leiomyoma obtained from patients who underwent hysterectomies at the gynecological surgery service of the HUUFMA. The rats were divided into two groups. Group I consisted of three rats in which the uterine leiomyoma had been implanted in the parietal peritoneum, and group II consisted of three rats in which the uterine leiomyoma was implanted in the subcutaneous tissue. The immunosuppressant mycophenolate mofetil (MMF) was administered orally by gavage (at a dose of 40 mg/kg of body weight) to prevent transplant rejection starting 15 days before the transplant and continuing throughout the entire experiment. After four weeks, necrosis and neovascularization were evaluated histologically in both groups and were classified as either absent or present. Lymphocytic inflammatory infiltration was also examined and classified as mild, moderate or intense (by hematoxylin and eosin staining), and fibrosis was classified as grade I-III (by Masson's trichrome staining). Necrosis was absent from all three rats in group I and was observed in only one rat from group II. Neovascularization was present in two rats from group I and in only one rat from group II. The lymphocytic inflammatory infiltrate was mild in two rats and moderate in one rat from group I, and it was moderate in two rats and intense in one rat from group II. Two rats from group 1 exhibited grade III fibrosis, and one rat presented grade I fibrosis. In group II, two rats presented grade I fibrosis and one rat had grade II fibrosis. When necrosis and neovascularization were evaluated as variables, group I demonstrated greater evidence of successful implantation when compared to group II, indicating that the peritoneal implantation technique produces better results than the subcutaneous approach (p

    Full Text Available Aim: The present study was conducted on advanced pregnant buffaloes suffering from uterine torsion to assess the status of fetus and uterus by transabdominal ultrasonography, and the findings were compared with normal advanced pregnant buffaloes. Materials and Methods: The study was conducted on 20 clinical cases of uterine torsion and 20 normal advanced pregnant buffaloes (control group. The lower ventral area just lateral to linea alba (on both sides of the udder in standing animals was scanned transabdominally by the two-dimensional convex transducer for various ultrasonographic findings. The data collected were statistically analyzed by “one-way ANOVA” and “independent sample t-test” using computerized SPSS 16.0 software program. Results: Transabdominal ultrasonography revealed dead fetus in 95% uterine torsion cases and proved useful in imaging internal structures of fetuses while no dead fetus was reported in the control group. Size of umbilicus was found significantly decreased (p0.05 in uterine torsion group. Average thickness of the uterine wall and mean pixel values of fetal fluids (echogenicity were found significantly increased (p<0.05 in uterine torsion affected buffaloes in comparison to control group. Conclusion: Status of fetus (whether live or dead, internal status of uterus, and its contents could be determined by transabdominal ultrasonography in uterine torsion cases and thus determining the prognosis of the uterine torsion cases before going for further manipulations. This will also help in taking all the precautions to avoid death of the fetus.

  16. Reducing blood loss during laparoscopic myomectomy by temporary uterine artery clamping using bulldog clamp

    Full Text Available Uterine myoma is the most common benign gynecologic tumor worldwide. Mini-invasive surgery has become popular for myomectomy, with advantages over laparotomy. However, reducing blood loss during laparoscopic myomectomy is a major concern for the surgeon because of the limitation in making a quick control bleeding during the operation. Several methods have proved to decrease blood flow, but are not always effective or available. We present a case of uterine myoma with the uterine arteries clamped by bulldog clamps during laparoscopic myomectomy. The myoma was removed successfully with minimal blood loss (<50 ml during the operation. This is an effective, safe, and reliable method for reducing bleeding during laparoscopic myomectomy that does not require ligation of the uterine artery.

    What is the central question of this study? Does fetal hypothyroidism in rats alter uterine contractions and structure in the adult offspring? What is the main finding and its importance? Our study indicated that maternal hypothyroidism during pregnancy increased gestational length and decreased litter size. In addition, maternal hypothyroidism caused delayed puberty onset, irregular uterine contractions and histological changes in the uterus in the female offspring. This model might contribute to a better understanding of the cellular and molecular mechanisms involved in uterine contractions in fetal hypothyroidism, studies which are not possible in humans, and might help to establish therapeutic methods for these disorders observed in uterine contractions. Thyroid hormones play an essential role in fetal growth. Hypothyroidism impairs reproductive function in both humans and animals. The aim of this study was to assess the effects of fetal hypothyroidism on uterine smooth muscle contraction and structure in the adult offspring. The control group of female Wistar rats consumed tap water, whereas the hypothyroid group received water containing 0.025% of 6-propyl-2-thiouracial throughout gestation from mating until delivery. Isometric contractility and histological changes in uterine tissue were evaluated in the adult female offspring. We tested the effects of carbachol (10 -10 -10 -3  m) and oxytocin (10 -13 -10 -8  m) on uterine smooth muscle contraction in the fetal hypothyroid (FH) and control groups. Compared with control uteri, carbachol induced contractions with lower amplitude in the FH group (area under the curve: 1820.0 ± 250.0 versus 1370.0 ± 125.0 a.u., control versus FH group, respectively, P muscle layer and the cross-sectional area of the uterus were also significantly lower in the FH group. Gestational length was longer and litter size smaller in FH rats compared with control animals; FH offspring also had delayed puberty. In conclusion

    A uterine arteriovenous malformation (AVM) is a rare cause of uterine bleeding. It may have varied presentations ranging from being completely asymptomatic; to features of congestive heart failure to vaginal bleeding which may at times life be threatening. Clinical findings in such cases are often un-reliable; requiring a high index of suspicion to make the diagnosis. Sonographic gray scale features are non-specific requiring confirmation with colour and spectral Doppler. We report a case of a 46-year-old lady who presented with heavy vaginal bleeding and ultrasound/colour Doppler evidence of uterine AVM managed by abdominal hysterectomy, describing the imaging features on ultrasound and Doppler. We also discuss in brief about this uncommon but serious condition which the radiologist/gynaecologist may encounter in thier practise. Uterine AV Malformation is a rare but potentially life-threatening cause of menorrhagia which must be kept in the differential diagnosis of sudden and massive vaginal bleeding. Ultrasound remains the modality of choice in diagnosing the condition which requires a high index of clinical suspicion. Color and spectral Doppler ultrasound should be used to supplement the findings and to confirm the diagnosis

    The cornerstone of concerns over trial of labor after cesarean (TOLAC) is the risk of uterine rupture. The purpose of this study was to document the rate of uterine rupture during TOLAC and to delineate its severity and consequences. We retrospectively collected the data on vaginal and cesarean deliveries after a previous cesarean section with specific emphasis on uterine rupture and dehiscence in our center from 2006 through 2013. 22,670 deliveries were registered, with 18.2% rate of cesarean section. 2890 women had a single cesarean scar; of them 1206 delivered vaginally and 194 were re-operated during unsuccessful TOLAC. Seven cases of uterine rupture and 16 cases of dehiscence were recorded. There were no maternal, intrapartum or neonatal deaths, and no cesarean hysterectomy. There was one re-laparotomy, one ICU admission, and one blood transfusion; one neonate was admitted to NICU. TOLAC was successful in 86.1% of cases. Cautious selection and close monitoring of candidates are the cornerstones of successful management of TOLAC. Readily available facilities for emergency cesarean delivery and concerted obstetrical team can save the mother and child from catastrophic complications.

    Flowering time is an important ecological trait that determines the transition from vegetative to reproductive growth. Flowering time in cotton is controlled by short-day photoperiods, with strict photoperiod sensitivity. As the CO-FT (CONSTANS-FLOWER LOCUS T) module regulates photoperiodic flowering in several plants, we selected eight CONSTANS genes (COL) in group I to detect their expression patterns in long-day and short-day conditions. Further, we individually cloned and sequenced their homologs from 25 different cotton accessions and one outgroup. Finally, we studied their structures, phylogenetic relationship, and molecular evolution in both coding region and three characteristic domains. All the eight COLs in group I show diurnal expression. In the orthologous and homeologous loci, each gene structure in different cotton species is highly conserved, while length variation has occurred due to insertions/deletions in intron and/or exon regions. Six genes, COL2 to COL5, COL7 and COL8, exhibit higher nucleotide diversity in the D-subgenome than in the A-subgenome. The Ks values of 98.37% in all allotetraploid cotton species examined were higher in the A-D and At-Dt comparison than in the A-At and D-Dt comparisons, and the Pearson’s correlation coefficient (r) of Ks between A vs. D and At vs. Dt also showed positive, high correlations, with a correlation coefficient of at least 0.797. The nucleotide polymorphism in wild species is significantly higher compared to G. hirsutum and G. barbadense, indicating a genetic bottleneck associated with the domesticated cotton species. Three characteristic domains in eight COLs exhibit different evolutionary rates, with the CCT domain highly conserved, while the B-box and Var domain much more variable in allotetraploid species. Taken together, COL1, COL2 and COL8 endured greater selective pressures during the domestication process. The study improves our understanding of the domestication-related genes/traits during cotton
