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

    Real-time quantitative polymerase chain reaction (RT-qPCR) is usually employed in gene expression studies in veterinary research, including in studies on canine pyometra. Canine pyometra is a common clinical disease in bitches. When using RT-qPCR, internal standards, such as reference genes, are necessary to investigate relative gene expression by quantitative measurements of mRNA levels. The aim of this study was to evaluate the stability of reference genes and select reference genes suitable for canine pyometra studies. We collected 24 bitch uterine tissue samples, including five healthy and 19 pyometra infected samples. These were used to screen the best reference genes of seven candidate genes (18SrRNA, ACTB, B2M, GAPDH, HPRT, RPL13A, and YWHAZ). The method of KH Sadek and the GeNorm, Normfinder, BestKeeper, and RefFinder software were used to evaluate the stability of gene expression in both pyometra and healthy uterine samples. The results showed that the expression stability of the candidate gene in pyometra and healthy tissues differed. We showed that YWHAZ was the best reference gene, which could be used as an accurate internal control gene in canine pyometra studies. To further validate this recommendation, the expression profile of a target gene insulin-like growth factor 1 receptor gene (IGF1R) was investigated. We found that the expression of IGF1R was significantly altered when different reference genes were used. All reference genes identified in the present study will enable more accurate normalization of gene expression data in both pyometra infected and healthy uterine tissues. PMID:27323194

    Newborn viability evaluation and early detection of fetal distress could contribute to reducing mortality at birth in canine species. High neonatal mortality rate in dogs is reported subsequent to complicated or uncomplicated whelping. Umbilical vein lactate and tocodynamometry could provide valuable clinical information to the obstetricians so that appropriate medical and surgical treatments or oxygen and warm administration can be properly and timely applied to mother and newborn pup. In humans, the fetal lactate level represents an objective indicator of fetal distress and a valid predictor of babies' survival. Fetal acidosis recognition by umbilical lactate (UL) measurement, APGAR score classification, and uterine activity monitoring during labour, can represent an advanced system in the evaluation of the canine newborn patient. The purpose of this study was to correlate UL levels with canine neonatal morbidity and mortality within 48 h of birth. We evaluated the relationship among neonatal parameters at birth (mucous membrane color, heart and respiratory rate, reflex irritability, mobility, suckling and vocalization, UL, weight, and temperature) with labour characteristics (uterine contractions recorded by the tocodynamometric system of Whelpwise ™ Veterinary Perinatal Specialties ®, delivery time, and pup presentation), in view to predict pup viability. We considered also vaginal parturition versus elective and emergency Caesarean section, and uterotonic drugs influence on delivery. Umbilical lactate concentration proved to be useful to predict canine neonatal mortality within 48 h of birth (P pups. Higher values of UL were related with distressed pups, whereas lower values characterized vigorous pups. Lactate concentrations lower than 5 mmol/L and APGAR scores higher than 9, related to mean delivery time of 105 min with effective uterine contractions (10 mm of Hg of strength or more, frequency from 4 to 12 contractions per hour, and 2-5 min in duration

  9. Steroidal regulation of uterine resistance to bacterial infection in livestock

    Full Text Available Abstract Postpartum uterine infections reduce reproductive efficiency and have significant animal welfare and economic consequences. Postpartum uterine infections are classified as nonspecific, but Arcanobacterium pyogenes and Escherichia coli are usually associated with them in cattle and sheep. Pyometra is the most common type of uterine infection in dairy cattle, and it is detected almost exclusively in cows with active corpora lutea. Luteal progesterone typically down-regulates uterine immune functions and prevents the uterus from resisting infections. Progesterone also can down-regulate uterine eicosanoid synthesis. This seems to be a critical event in the onset of uterine infections, because eicosanoids can up-regulate immune cell functions in vitro. In addition, exogenous prostaglandin F2 alpha stimulates uterine secretion of prostaglandin F2 alpha and enhances immune functions in vivo. Thus, one may hypothesize that eicosanoids can override the negative effects of progesterone and that the up-regulatory effects of exogenous prostaglandin F2 alpha allow the uterus to resolve an infection, regardless of progesterone concentrations. Based on the results of studies to test that hypothesis, cows, sheep, and pigs in various physiological statuses are resistant to intrauterine infusions of Arcanobacterium pyogenes and Escherichia coli, unless progesterone concentrations are increased. In sheep and pigs, exogenous prostaglandin F2 alpha stimulates uterine production of prostaglandin F2 alpha and allows the uterus to resolve Arcanobacterium pyogenes-Escherichia coli-induced infections, even when progesterone is maintained at luteal phase concentrations before and after treatment. Prostaglandin F2 alpha is a proinflammatory molecule that stimulates the production of various proinflammatory cytokines, and it may enhance uterine production of leukotriene B4. Proinflammatory cytokines and leukotriene B4 enhance phagocytosis and lymphocyte functions

    Full Text Available The diversity of the uterine bacterial composition in dairy cows is still poorly understood, although the emerging picture has shown to be increasingly complex. Understanding the complexity and ecology of microorganisms in the uterus of postpartum dairy cows is critical for developing strategies to block their action in reproductive disorders, such as metritis/endometritis. Here, we used PCR-Denaturing Gradient Gel Electrophoresis (DGGE and DNA pyrosequencing to provide a comprehensive description of the uterine bacterial diversity and compare its succession in healthy, metritic and endometritic Holstein dairy cows at three intervals following calving. Samples were collected from 16 dairy cows housed in a dairy farm located in upstate New York. PCR-DGGE revealed a complex profile with extensive differences in the community structure. With few exceptions, clustering analysis grouped samples from cows presenting the same health status. Analysis of >65,000 high-quality 16S rRNA gene sequences showed that the uterine bacterial consortia, regardless of the health status, is mainly composed of members of the phyla Bacteroidetes, Fusobacteria, Firmicutes, Proteobacteria, and Tenericutes. In addition to these co-dominant phyla, sequences from Spirochaetes, Synergistetes, and Actinobacteria appear less frequently. It is possible that some sequences detected in the uterine fluid resulted from the presence of fecal or vaginal contaminants. Overall, the bacterial core community was different in uterine fluid of healthy cows, when compared to cows suffering from postpartum diseases, and the phylogenetic diversity in all the combined samples changed gradually over time. Particularly at the 34-36 days postpartum (DPP, the core community seemed to be specific for each health status. Our finding reveals that the uterine microbiota in dairy cows varies according with health status and DPP. Also, it adds further support to the hypothesis that there is uterine

    Canine herpesvirus (CHV) is an attractive candidate not only for use as a recombinant vaccine to protect dogs from a variety of canine pathogens but also as a viral vector for gene therapy in domestic animals. However, developments in this area have been impeded by the complicated techniques used for eukaryotic homologous recombination. To overcome these problems, we used bacterial artificial chromosomes (BACs) to generate infectious BACs. Our findings may be summarized as follows: (i) the CHV genome (pCHV/BAC), in which a BAC flanked by loxP sites was inserted into the thymidine kinase gene, was maintained in Escherichia coli; (ii) transfection of pCHV/BAC into A-72 cells resulted in the production of infectious virus; (iii) the BAC vector sequence was almost perfectly excisable from the genome of the reconstituted virus CHV/BAC by co-infection with CHV/BAC and a recombinant adenovirus that expressed the Cre recombinase; and (iv) a recombinant virus in which the glycoprotein C gene was deleted was generated by lambda recombination followed by Flp recombination, which resulted in a reduction in viral titer compared with that of the wild-type virus. The infectious clone pCHV/BAC is useful for the modification of the CHV genome using bacterial genetics, and CHV/BAC should have multiple applications in the rapid generation of genetically engineered CHV recombinants and the development of CHV vectors for vaccination and gene therapy in domestic animals.

Blood samples were collected at weeks 3, 5 and 7 pp to determine plasma progesterone concentrations to monitor ovarian activity. According to the bacteriological examination, cows were classified into four groups. The first group (n = 32; 49%) comprised cows negative for bacteria at weeks 5 and 7 pp. The second group (n = 11; 17%) comprised cows with bacterial infections at week 5 pp but that were clear of infection at week 7 pp. The third group (n = 12; 19%) comprised cows without bacteria at week 5 pp but that acquired an infection by week 7 pp. The fourth group (n = 10; 15%) comprised cows with bacterial infections at weeks 5 and 7 pp (persistence of infection).

    Clinical diagnostic criteria for sepsis (systemic inflammatory response syndrome caused by infection) are unspecific and, therefore, biomarkers for sepsis diagnosis are needed for appropriate treatment and patient survival. Pyometra, a common disease caused by bacterial infection of the uterus, results in sepsis in nearly 60% of cases in dogs. We used dogs with pyometra as a natural model for sepsis and collected serum samples from 39 dogs, of which 22 with pyometra and 17 healthy controls. Dogs with pyometra were further grouped into dogs with sepsis (n=18) and without sepsis (n=4). Serum concentrations of a panel of cytokines, including keratinocyte-derived chemokine (KC)-like, granulocyte-macrophages colony stimulating factor (GM-CSF), interleukin (IL)-2, IL-4, IL-6, IL-7, IL-8, IL-10, IL-15, IL-18, chemokine C-X-C motif ligand (CXCL)10 and tumor necrosis factor (TNF)-α, were measured using multiplex analyses. Serum C-reactive protein (CRP) levels were determined using an automated immunoturbidimetric assay. In addition to physical examination hematological and serum biochemical analyses were performed to evaluate the overall status of the dogs. Significantly higher concentrations of KC-like (757 vs 304 pg/ml) were detected in dogs with pyometra as compared to healthy dogs. Within the pyometra group, dogs with sepsis compared to dogs without sepsis had a higher KC-like concentration (873 vs 300 pg/ml). Hemoglobin levels were significantly lower in dogs with pyometra compared to healthy dogs, regardless of the presence or absence of sepsis, and correlated negatively with KC-like. KC-like concentrations correlated positively with CRP, number of hospitalization days, number of monocytes, concentrations of IL-8, and percentage band neutrophils. Our data suggest that bacterial infection triggers the expression of KC-like and further studies are warranted of KC-like as a possible biomarker for diagnosing sepsis and uterine bacterial infection in dogs.

    Pyometra, a prevalent infectious uterine disease that affects intact middle-aged bitches, is typically associated with Escherichia coli. Our hypotheses were (i) that bacterial adhesion to canine endometrium differs between different stages of the oestrous cycle and (ii) that the adhesin FimH facilitates this adhesion. Twelve post-pubertal, ovariectomized greyhound bitches were treated with exogenous hormones to simulate different stages of the oestrous cycle. Tissue samples from each uterus were incubated with a pathogenic E. coli strain carrying the fimH gene, but no other adhesin genes (P4-wt)--or an E. coli strain in which fimH was insertionally inactivated (P4-∆fimH::kan)--or with phosphate-buffered saline as a negative control. After washing, tissue samples were homogenized for quantification of adherent bacteria. The differences in binding to canine endometrium at different stages of the oestrous cycle were not significant. However, the mean difference in binding of the P4-wt and the P4-∆fimH::kan across all stages of the simulated oestrous cycle was significant (p < 0.001 by paired t-test on geometric means). Individual differences in numbers of P4-wt bacteria bound between dogs might suggest genetic variations or epigenetic differences in FimH receptor expression by the endometrium, unrelated to the stage of the oestrous cycle.

    In this study, 908 bacterial pathogens from defined infections of dogs and cats were tested for their susceptibility to the novel fluoroquinolone pradofloxacin, which was approved in 2011 for use in cats and dogs. Most of the bacteria tested (Staphylococcus aureus, Staphylococcus pseudintermedius, Escherichia coli, β-haemolytic streptococci, Pasteurella multocida and Bordetella bronchiseptica) exhibited low pradofloxacin MIC(90) values of ≤ 0.25 μg/ml. Solely Proteus spp. and Pseudomonas aeruginosa had higher MIC(90) values of ≥ 4 μg/ml. Only six (3.4%) of 177 S. pseudintermedius and 12 (5.3%) of 227 E. coli isolates showed pradofloxacin MICs of ≥ 2 μg/ml. Analysis of the quinolone resistance determining regions of the target genes identified double mutations in GyrA that resulted in amino acid exchanges S83L+D87N or S83L+D87Y and single or double mutations in ParC that resulted in amino acid exchanges S80I or S80I+E84G in all 12 E. coli isolates. The six S. pseudintermedius isolates exhibited amino acid exchanges S84L or E88K in GyrA and S80I in GrlA. Comparative analysis of the MICs of pradofloxacin and the MICs determined for enrofloxacin and its main metabolite ciprofloxacin, but also marbofloxacin, orbifloxacin, difloxacin and ibafloxacin was conducted for the target pathogens S. pseudintermedius, E. coli and P. multocida. This comparison confirmed that pradofloxacin MICs were significantly lower than those of the other tested fluoroquinolones. PMID:22939523

    Septic peritonitis occurs relatively commonly in dogs. Secondary septic peritonitis is usually associated with perforation of intestines or infected viscera, such as the uterus in pyometra cases. The aim of this study was to evaluate the bacterial flora in the ovarian bursae of intact bitches as a potential source of contamination. One hundred forty dogs, clinically suspected of pyometra, were prospectively enrolled. The control group consisted of 26 dogs that underwent elective ovariohysterectomies and 18 dogs with mammary gland tumors that were neutered at the time of mastectomy. Bacteriology samples were taken aseptically at the time of surgery from the bursae and the uterus in all dogs. Twenty-two dogs that were clinically suspected of pyometra had sterile uterine content ("mucometra" cases); the remaining 118 had positive uterine cultures ("pyometra" cases) and septic peritoneal fluid was present in 10% of these cases. Of the 118 pyometra cases, 9 had unilateral and 15 had bilateral bacterial colonization of their ovarian bursae. However, the bacteria from the ovarian bursa were similar to those recovered from the uterine pus in only half of the cases. Furthermore, positive bursae were also seen in one mucometra dog (unilateral) and in four control dogs (two unilateral and two bilateral). The data illustrate that the canine ovarian bursa can harbor bacteria. The biological importance of these isolations remains unclear. PMID:25127745

    Escherichia coli uterine infection originates different clinical outcomes in the canine and bovine species. Here, E. coli strains isolated from bovine clinical metritis and canine pyometra cases were analyzed by PFGE, screened for 33 virulence factor (VF) genes and for phylogenetic grouping. Bovine and canine E. coli isolates presented a low degree of genetic similarity. Canine E. coli strains belonged to phylogenetic group B2 and presented a high number of VF genes, whereas bovine E. coli strains belonged to phylogenetic groups B1 and A and had a low number of VF genes. In conclusion, E. coli strains isolated from cow clinical metritis had a low potential of virulence. In contrast, bitch pyometra E. coli isolates had a high virulence potential, which might be relevant in the pathogenesis of pyometra. These differences between canine and bovine E. coli isolates may partially explain the different outcomes of the uterine infection in the two species. PMID:24598134

  9. Acute puerperal uterine inversion

    International Nuclear Information System (INIS)

    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.

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

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

    The objective of this study was to evaluate the progression of the uterine microbiota from calving until establishment of metritis. Uterine swabs (n = 72) collected at 0, 2, and 6 ± 2 days postpartum (dpp) from 12 metritic and 12 healthy cows were used for metagenomic sequencing of the 16S rRNA gene on the Illumina MiSeq platform. A heat map showed that uterine microbiota was established at calving. The microbiota changed rapidly from 0 to 6 ± 2 dpp, with a decrease in the abundance of Proteobacteria and an increase in the abundance of Bacteroidetes and Fusobacteria, which were dominant in metritic cows. Uterine microbiota composition was shared; however, metritic and healthy cows could be discriminated using relative abundance of bacterial genera at 0, 2, and 6 ± 2 dpp. Bacteroides was the main genus associated with metritis because it was the only genus that showed significantly greater abundance in cows with metritis. As the abundance of Bacteroides organisms increased, the uterine discharge score, a measure of uterine health, worsened. Fusobacterium was also an important genus associated with metritis because Fusobacterium abundance increased as Bacteroides abundance increased and the uterine discharge score worsened as the abundance increased. The correlation with uterine discharge score and the correlation with Bacteroides or Fusobacterium showed that other bacteria, such as Helcoccocus, Filifactor, and Porphyromonas, were also associated with metritis. There were also bacteria associated with uterine health, such as “Candidatus Blochmannia,” Escherichia, Sneathia, and Pedobacter. PMID:26150453

    Cyclic or irregular uterine bleeding is common in perimenarchal and perimenopausal women with or without endometrial hyperplasia. The disturbance often requires surgical treatment because of its negative effects on both blood loss and abnormal endometrial growth including the development of endometrial cancer. The endometrium is often overstimulated during the perimenopausal period when estrogen/progesterone production is unbalanced. A therapeutical approach with gonadotropin-releasing hormone agonist (GnRHa) was proposed in a depot formulation (Zoladex) that induces a sustained and reversible ovarian suppression. To avoid the risk of osteoporosis and to obtain adequate endometrial proliferation and differentiation during ovarian suppression, transdermal 17-beta-estradiol and oral progestin were administered. Results of 20 cases versus 20 controls showed a reduction of metrorrhagia, a normalization of hemoglobin plasma concentration, and an adequate proliferation and secretory differentiation of the endometrium of patients with abnormal endometrial growth. Abnormal uterine bleeding is mainly due to uterine fibrosis and an inadequate estrogen and/or progesterone production or to a disordered estrogen transport from blood into the endometrium. In premenopausal women, endometrial hyperplasia may be part of a continuum that is ultimately manifested in the histological and biological pattern of endometrial carcinoma. The regression of endometrial hyperplasia obtained by using the therapeutic regimen mentioned above represents a preventive measure for endometrial cancer. Finally the normalization of blood loss offers a good medical alternative to surgery for patients with DUB. PMID:7978956

  18. Diagnostic and prognostic markers for uterine diseases in dogs.

    Hagman, R

    2014-06-01

    Common uterine diseases in female dogs include cystic endometrial hyperplasia (CEH), mucometra, hydrometra and pyometra. It is important in clinical practice to recognize pyometra because it is potentially life-threatening due to the systemic illness induced by bacterial infection of the uterus. In contrast, the uterine content is sterile in CEH and mucometra/hydrometra, and clinical signs are mostly mild or absent. Optimal treatment depends on the type of uterine disease and its severity, but diagnosis and prognosis determination may be challenging and the diseases difficult to separate clinically. Diagnostic findings or biomarkers that may aid in the differentiation of the diseases are valuable, especially when several bitches are admitted with a fluid-filled uterus during night-time, and it has to be decided which patient to operate on first. Additionally, some variables may indicate outcome as measured by mortality or morbidity. If the uterus is not enlarged or fluid-filled, detection of uterine disease can be even more difficult. In this study, clinically useful variables with possible diagnostic or prognostic value for uterine diseases in dogs are discussed. PMID:24947856

    Full Text Available The pyometra is a disease that affects middle age and elderly female dogs during diestrus. Hormonal, microbiological, biochemical and hematological aspects are well described. However, few studies have evaluated the role of each in the prognosis of canine pyometra. The aim of this study was to identify markers associated with clinical worsening of dogs with pyometra. We prospectively evaluated 80 dogs with pyometra treated surgically. Group 1 consisted of dogs that were discharged within 48 hours after surgery and Group 2 consisted of those who required prolonged hospitalization or died. The findings of hematological, biochemical and blood lactate levels were compared between groups and variables such as bacterial multidrug resistance, systemic inflammatory response syndrome (SIRS, hyperlactatemia and increased creatinine were analyzed through the dispersion of frequencies between groups. Among the variables studied, the presence of SIRS and elevated serum creatinine >2.5mg/mL were effective in predicting the worsening of the disease and can be used as prognostic markers of canine pyometra.

Other intrinsic factors such as primiparity, uterine hypotonia, various placental localizations, fundic myoma or short umbilical cord were also reported. The diagnosis of the uterine inversion is mainly supported by clinical symptoms. It is based on three elements: haemorrhage, shock and a strong pelvic pain. The immediate treatment of the uterine inversion is required. It is based on a medical reanimation associated with firstly a manual reduction then surgical treatment using various techniques. We report an observation of a 25 years old grand multiparous patient with a subacute uterine inversion after delivery at home. PMID:21516244

    Doppler ultrasound is a useful diagnosis tool to evaluate uterine blood flow in different canine reproductive states. The aim of this study was to describe and compare uterine blood flow in bitches suffering from cystic endometrial hyperplasia (CEH) and CEH-pyometra complex (CEH-P). Ninety diestrous bitches were clinically, hematologically, and ultrasonographically classified into four groups: (1) clinical signs, leukocytosis, CEH, and uterine luminal contents (CEH-P, n = 31); (2) asymptomatic bitches with CEH and uterine contents (CEH-C, n = 15); (3) asymptomatic bitches with CEH without uterine contents (CEH, n = 16); and (4) normal diestrous bitches (ND, n = 28). The widest cross-sectional diameter and uterine wall thickness (W) of uterine horns were measured using two-dimensional ultrasound. Peak systolic velocity and end diastolic velocity of uterine arteries were measured by Doppler ultrasound in all the bitches. Peak systolic velocity and end diastolic velocity were higher in CEH-P than in CEH-C, CEH, and ND (P  0.1). Conversely, resistance index (RI) reported lower values in CEH-P than that in the other three groups (P  0.1). When all the bitches were considered, correlation between RI and cross-sectional diameter was r = -0.69 (P  0.1). It is concluded that the uterine artery blood flow velocity of bitches suffering from pyometra was higher, not only from normal bitches, but also from females with endometrial hyperplasia. Furthermore, endometrial hyperplasia, accompanied or not by luminal contents, had a higher blood flow velocity than normal uterus. Hemodynamic parameters appear as useful markers to differentiate uterine pathologic conditions. PMID:26810829

    Building a training system for medical personnel to properly interpret fetal heart rate tracing requires developing accurate models that can relate various signal patterns to certain pathologies. In addition to modeling the fetal heart rate signal itself, the change of uterine pressure that bears strong relation to fetal heart rate and provides indications of maternal and fetal status should also be considered. In this work, we have developed a group of parametric models to simulate uterine contractions during labor and delivery. Through analysis of real patient records, we propose to model uterine contraction signals by three major components: regular contractions, impulsive noise caused by fetal movements, and low amplitude noise invoked by maternal breathing and measuring apparatus. The regular contractions are modeled by an asymmetric generalized Gaussian function and least squares estimation is used to compute the parameter values of the asymmetric generalized Gaussian function based on uterine contractions of real patients. Regular contractions are detected based on thresholding and derivative analysis of uterine contractions. Impulsive noise caused by fetal movements and low amplitude noise by maternal breathing and measuring apparatus are modeled by rational polynomial functions and Perlin noise, respectively. Experiment results show the synthesized uterine contractions can mimic the real uterine contractions realistically, demonstrating the effectiveness of the proposed algorithm.

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

  5. Radiological appearances of uterine fibroids

    International Nuclear Information System (INIS)

    Uterine fibroids, also known as leiomyomas, are the commonest 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 USG, they can be further characterized with MRI. They are usually easily recognizable, but degenerate fibroids can have unusual appearances. In this article, we describe the appearances of typical and atypical uterine fibroids, unusual fibroid variants and fibroid mimics on different imaging modalities. Knowledge of the different appearances of fibroids on imaging is important as it enables prompt diagnosis and thereby guides treatment

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

  7. Uterine arterial embolization for uterine leiomyoma: efficacy and clinical outcome

    International Nuclear Information System (INIS)

    To determine the efficacy and clinical outcome of uterine arterial embolization as a new approach to the management of uterine leiomyomas. Uterine arterial embolization was performed in 21 patients aged 26-62(mean, 42) years. Twenty of these had menorrhagia, dysmenorrhea, and mass-related symptoms (low abdominal discomfort, backache, urinary frequency, etc.) and one was diagnosed incidentally.

    To determine the efficacy and clinical outcome of uterine arterial embolization as a new approach to the management of uterine leiomyomas. Uterine arterial embolization was performed in 21 patients aged 26-62(mean, 42) years. Twenty of these had menorrhagia, dysmenorrhea, and mass-related symptoms (low abdominal discomfort, backache, urinary frequency, etc.) and one was diagnosed incidentally. Bilateral uterine arteries were selected individually and polyvinyl alcohol and/or gelfoam was used as an embolic material. Nineteen patients were followed up after embolization. Seventeen (89.5 %)reported satisfactory improvement of symptoms and follow-up sonography three months later showed a 58.5 % reduction in mean myoma volume.

  9. Carcinoma of the uterine cervix

    International Nuclear Information System (INIS)

    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.)

  10. Molecular characterisation of the uterine microbiome of dairy cows suffering from endometritis, metritis, and pyometra

    DEFF Research Database (Denmark)

    Knudsen, Lif Rødtness Vesterby

    Postpartum uterine disease is a problem in dairy herds. Approximately 90% of dairy cows experience postpartum bacterial contamination of the uterus. Most of the cows are able to clear the infection within 8 weeks in the process of involution, but up to 20% of the cows develop metritis, which is...... infection throughout the uterine wall; and in some herds, 30-50% of cows develop endometritis, which is infection in the inner lining of the uterus. Pyometra is a related postpartum uterine disease, which is thought to occur when a cow with endometritis ovulates, and the cervix closes. The diseases are...... the mucosal layer of the uterus, the endometrium. It was hypothesised that pathogenic bacteria in the uterus initially adhere to the endometrium to cause disease, and that the chance of identifying pathogens is higher in examinations of endometrial biopsies than in uterine flush samples. In order to...

    The diagnostic workup for canine claw disease consists of a good history and complete clinical examination which may provide clues for a possible underlying disorder. In dogs with claw disease but no other clinical or historical signs, further recommended diagnostic procedures include cytological evaluation of impression smears or discharge from the claw fold, bacterial culture and sensitivity testing, biopsy of the claw matrix, and an elimination diet for 6 to 8 weeks. If no underlying disease can be identified, trial treatment with essential fatty acid supplementation, vitamin E, or a combination of doxycycline hydrochloride and niacinamide may be useful. In some patients, onychectomy of all claws may be considered. PMID:10563005

    Full Text Available Leishmania infantum is the obligatory intracellular parasite of mammalian macrophages and causes zoonotic visceral leishmaniasis (ZVL. The presence of infected dogs as the main reservoir host of ZVL is regarded as the most important potential risk for human infection. Thus the prevention of canine visceral leishmaniasis (CVL is essential to stop the current increase of the Mediterranean visceral leishmaniasis. Recently considerable advances in achieving protective immunization of dogs and several important attempts for achieving an effective vaccine against CVL lead to attracting the scientists trust in its important role for eradication of ZVL. This paper highlights the recent advances in vaccination against canine visceral leishmaniasis from 2007 until now.

    We sought to evaluate the clinical feasibility and mid- to long-term effects of laparoscopic uterine artery occlusion before myomectomy in the treatment of uterine myomas. A total of 566 patients with uterine myoma were treated by laparoscopic uterine artery occlusion before myomectomy from October 2001 through July 2007. Mean blood loss was 88.2 +/- 52.7 mL (95% CI 82.7-93.8). The highest postoperative temperature was 37.8 +/- 0.3 degrees C, and the postoperative morbidity was 5.7% (32/566). Number of days to the return of bowel movement was 1.9 +/- 0.5d and in hospital stay after surgery was 7.7 +/- 2.5d. Complications included 2 instances of subcutaneous emphysema, 1 of vaginal bleeding, and 3 of mild intestinal obstruction. At a median of 26.3 months (range 6-69 months) of follow-up, the rate of myoma recurrence was 3.0% (15/517), uterus volume reduction was 48.9%, and correction of menstruation abnormality was 97.1% (502/517). Laparoscopic uterine artery occlusion before myomectomy can expand myomectomy indications with better results. PMID:18439509

    2016-03-01

    Full Text Available Leiomyomas or myomas of the uterus, also known as a fibroid uterus, are the most common tumors of the uterus. They are benign neoplasms of smooth muscle origin with various degrees of fibrous connective tissue. These tumors can develop in any part of the female genital tract where there is smooth muscle or fibrous tissue, even in the ovary, broad ligament, and vagina. They need to be differentiated from adenomyosis and intracavitary polyps. They mostly remain asymptomatic but sometimes they cause significant morbidity. In such situations, hysterectomy or other surgical intervention is indicated. On ultrasonography, most uterine leiomyomas typically appear as well-defined, solid masses. Their echogenicity is usually similar to that of the myometrium, but sometimes they are hypoechoic. They often show some posterior acoustic shadowing. Variants of leiomyomas occur when they undergo cystic degeneration, hyalinization, or calcification. In such situations, determining a diagnosis is sometimes difficult. Magnetic resonance imaging can be used in this situation for an accurate diagnosis.

    Van Heertum, Kristin; Barmat, Larry

    2014-11-01

    In recent years, there has been an increasing focus on the contributory role of uterine fibroids to infertility. The prevalence of these tumors increases with age, which becomes significant as more women are delaying childbearing. Therefore, fibroids and infertility frequently occur together. Treatment varies with fibroid location and size. The various methods of treatment include open myomectomy, laparoscopic or robot-assisted myomectomy, medical treatment, uterine artery embolization and magnetic resonance guided focused ultrasound surgery. While there is a general consensus on the treatment of submucosal fibroids, the management of intramural fibroids in the infertility patient remains controversial. This paper aims to review and summarize the current literature in regards to the approach to uterine fibroids in the infertile patient. PMID:25482490

The canine (Canis familiaris) CD1 locus was previously found to contain three functional CD1A genes: canCD1A2, canCD1A6, and canCD1A8, where two variants of canCD1A8, canCD1A8.1 and canCD1A8.2, were assumed to be allelic variants. However, we hypothesized that these rather represented two...... separate genes. Sequencing of three overlapping bacterial artificial chromosomes (BACs) spanning the entire canine CD1 locus revealed canCD1A8.2 and canCD1A8.1 to be located in tandem between canCD1A7 and canCD1C, and canCD1A8.1 was consequently renamed canCD1A9. Green fluorescent protein (GFP......)-fused canine CD1 transcripts were recombinantly expressed in 293T cells. All proteins showed a highly positive GFP expression except for canine CD1d and a splice variant of canine CD1a8 lacking exon 3.

  20. Asymptomatic uterine fibroids.

    Science.gov (United States)

    Divakar, Hema

    2008-08-01

    It is estimated that at least 50% of fibroids are asymptomatic, but this figure is likely to be an underestimate as it is based on women in whom fibroids are found incidentally during another procedure (e.g. cervical screening), and there is little, if any, data from population studies on the true incidence of fibroids. If a prevalence of 50% by 50 years of age is accepted, a large number of women have asymptomatic fibroids. Working on the cliché, 'if it ain't broken, don't fix it', it may seem surprising that there should be a chapter dedicated to the issue of asymptomatic fibroids, since the simplistic approach might be to leave the asymptomatic fibroids well alone. However, asymptomatic fibroids may become symptomatic in the future, so it may be wiser to treat fibroids before they grow to a size when they become symptomatic, or treatment becomes more challenging, especially in young women who may desire fertility at a later stage, and in view of the fact that many women are starting their families in their mid-thirties when they have a 30% chance of having a fibroid(s). Despite their common occurrence, fibroids are still poorly understood. It is not known why they form in the first place, what determines their number and ultimate size, the best treatment approaches, or the factors that determine which women develop symptoms. Even when women present with disorders such as infertility, pelvic pain and abnormal bleeding, it is not always possible to be certain that a given myoma is not simply an innocent bystander rather than the cause of the symptom. This chapter addresses the challenging issue of what to do when fibroids are diagnosed incidentally. Firstly, there is the need to ascertain that the pelvic mass palpated is indeed a fibroid, and not an early, more sinister tumour, especially if conservative management is adopted. In addition, there is the issue of size, position and potential for becoming symptomatic at a later date. With the availability of uterine

    Uterine myoma is one of the most commonly encountered gynecologic problem in daily ultrasonographic practice, and is one of the few conditions with which specific histologic diagnosis is possible by ultrasonography in selected patients as well. We recently analysed ultrasonograms of 132 cases of uterine myoma and 31 cases that showed similar ultrasonographic findings of myoma, histopathologically verified in both cases. The results were as follows. 1. The diagnostic accuracy by ultrasonography was 93%. 2. The most common ultrasonographic findings of uterine myoma were nodular enlargement of uterus and irregular internal echo texture changes. 3. It was not possible to differentiate the various kinds of secondary degeneration by ultrasonography, except for calcification and cystic change. 4. It was usually unable to differentiate solitary from multiple myoma, and subserosal, interstitial and submucosal types from each other by ultrasonographic findings alone, except for the usual cases of exophytically growing subserosal mass. 5. The most frequent disease that is hard to differentiate from small uterine myoma was adenomyosis, and therefore it is considered necessary to include the adenomyosis in differential diagnosis in the diagnosis of myoma causing moderately enlarged uterus.

    Gastrointestinal (GI) microbes have important roles in the nutritional, immunological, and physiologic processes of the host. Traditional cultivation techniques have revealed bacterial density ranges from 10(4) to 10(5) colony forming units (CFU)/g in the stomach, from 10(5) to 10(7) CFU/g in the small intestine, and from 10(9) to 10(11) CFU/g in the colon of healthy dogs. As a small number of bacterial species can be grown and studied in culture, however, progress was limited until the recent emergence of DNA-based techniques. In recent years, DNA sequencing technology and bioinformatics have allowed for better phylogenetic and functional/metabolic characterization of the canine gut microbiome. Predominant phyla include Firmicutes, Bacteroidetes, Fusobacteria, Proteobacteria, and Actinobacteria. Studies using 16S ribosomal RNA (rRNA) gene pyrosequencing have demonstrated spatial differences along the GI tract and among microbes adhered to the GI mucosa compared to those in intestinal contents or feces. Similar to humans, GI microbiome dysbiosis is common in canine GI diseases such as chronic diarrhea and inflammatory bowel diseases. DNA-based assays have also identified key pathogens contributing to such conditions, including various Clostridium, Campylobacter, Salmonella, and Escherichia spp. Moreover, nutritionists have applied DNA-based techniques to study the effects of dietary interventions such as dietary fiber, prebiotics, and probiotics on the canine GI microbiome and associated health indices. Despite recent advances in the field, the canine GI microbiome is far from being fully characterized and a deeper characterization of the phylogenetic and functional/metabolic capacity of the GI microbiome in health and disease is needed. This paper provides an overview of recent studies performed to characterize the canine GI microbiome. PMID:22647637

    2012-08-15

    The potentially fatal hemostatic disorder of disseminated intravascular coagulation (DIC) is initiated in bacterial sepsis by lipopolysaccharide (LPS)-induced tissue factor (TF) expression on monocytes. Interleukin-10 (IL-10) is a potent inhibitory cytokine that downregulates monocyte inflammatory and procoagulant responses. We hypothesized that canine recombinant IL-10 (rIL-10) would inhibit LPS-induced TF upregulation on canine monocytes in a dose-dependent manner. Canine peripheral blood mononuclear cells (PBMC), obtained by double-density gradient centrifugation, and monocytes, purified from PBMC by immunomagnetic bead separation with an anti-canine CD14 antibody (Ab), were stimulated in suspension with LPS (0.1-1000 ng/mL) for various times. Recombinant IL-10 (10-5000 pg/mL) was added with LPS or up to 2h later. Tissue factor procoagulant activity was measured by cleavage of a chromogenic substrate by activated Factor X generated by the TF-factor VII complex. We found that rIL-10, when given concurrently or 1h after LPS, strongly inhibited LPS-induced TF procoagulant activity in canine PBMC and monocytes. This inhibition was dose-dependent and blocked by an anti-canine IL-10 Ab. Our results indicate that rIL-10 effectively inhibits LPS-induced TF upregulation in canine monocytes and could potentially be useful in limiting the development of DIC in dogs with endotoxemia.

    Despite the fact that the mast cell tumor is a common neoplasm of the dog, we still have only a meager understanding of its etiology and biologic behavior. Many of the published recommendations for treatment are based on opinion rather than facts derived from careful studies and should be viewed with some skepticism. Because of the infrequent occurrence of this tumor in man, only a limited amount of help can be expected from human oncologists; therefore, burden of responsibility for progress in predicting behavior and developing treatment effective for canine mast cell tumors must fall on the shoulders of the veterinary profession.

    Benign uterine disease is a common entity affecting women of all ages. Ultrasound has historically been the predominant imaging method used in the evaluation of benign gynaecological disease, magnetic resonance imaging (MRI) being reserved for use in the staging of malignant uterine and cervical disease. MRI is now increasingly used in the diagnosis of benign uterine disease as well as a tool for problem-solving in cases of diagnostic dilemma. It allows detailed assessment of benign conditions, such as endometrial lesions, leiomyomas, and adenomyosis, and can be helpful in the stratification of patients to different treatment modalities, including surgical resection, uterine artery embolization, and medical therapies. In this article, we review the MRI findings in the common benign uterine diseases

    2011-07-01

    Full Text Available Abstract Background Contamination from fecal bacteria in recreational waters is a major health concern since bacteria capable of causing human disease can be found in animal feces. The Dog Beach area of Ocean Beach in San Diego, California is a beach prone to closures due to high levels of fecal indicator bacteria (FIB. A potential source of these FIB could be the canine feces left behind by owners who do not clean up after their pets. We tested this hypothesis by screening the DNA isolated from canine feces for the bacteriophage-encoded stx gene normally found in the virulent strains of the fecal bacterium Escherichia coli. Results Twenty canine fecal samples were collected, processed for total and bacterial fraction DNA, and screened by PCR for the stx gene. The stx gene was detected in the total and bacterial fraction DNA of one fecal sample. Bacterial isolates were then cultivated from the stx-positive fecal sample. Eighty nine of these canine fecal bacterial isolates were screened by PCR for the stx gene. The stx gene was detected in five of these isolates. Sequencing and phylogenetic analyses of 16S rRNA gene PCR products from the canine fecal bacterial isolates indicated that they were Enterococcus and not E. coli. Conclusions The bacteriophage-encoded stx gene was found in multiple species of bacteria cultivated from canine fecal samples gathered at the shoreline of the Dog Beach area of Ocean Beach in San Diego, California. The canine fecal bacteria carrying the stx gene were not the typical E. coli host and were instead identified through phylogenetic analyses as Enterococcus. This suggests a large degree of horizontal gene transfer of exotoxin genes in recreational waters.

    2011-03-01

    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.

    In the mare, the low-volume uterine lavage technique allows for bacterial sampling of the entire uterine lumen and is usually performed after obtaining the traditional double-guarded endometrial swab for aerobic culture and cytology and before procurement of an endometrial biopsy sample during a breeding soundness examination. The purpose of this study was to explore the potential effects of the low-volume lavage on the endometrial biopsy classification and polymorphonuclear cell (PMNs) infiltration in the context of a breeding soundness examination. Fourteen light horse mares of mixed breed, age 7 to 21 years, with known reproductive history, were included in the study, matched by age and reproductive history, and then divided into treatment and control groups. Transrectal palpation and ultrasonography, endometrial swabbing, and the first endometrial biopsy were performed in all mares. Low-volume uterine lavage was performed in the treatment group but not the control group. After either the lavage or a 15-minute rest, a second endometrial biopsy was obtained from both the control and treatment groups. Endometrial swabs and effluent from the low-volume lavages were submitted for aerobic culture and sensitivity. Biopsy samples were fixed in Bouin's solution for 24 hours, processed, stained with hematoxylin and eosin, and then viewed under bright light microscopy. Additional staining with anti-neutrophil elastase antibody (ab68672) was performed for indirect immunohistochemistry. All samples were interpreted by a blinded observer. When the first (pre-uterine lavage) and second (post-uterine lavage) biopsies were compared using a mixed-effects logistic regression, there was no difference in endometrial biopsy classification (P = 0.74), presence of PMNs in blood vessels (P = 0.728), or infiltration of PMNs in the tissue (P = 0.934) between the treatment and control groups. In this study, the low-volume uterine lavage did not affect the endometrial biopsy

    Normal pregnancy involves dramatic remodeling of the uterine vasculature, with abnormal vascular adaptations contributing to pregnancy diseases such as preeclampsia. The peptide hormone relaxin is important for the renal and systemic hemodynamic adaptations to pregnancy, and has been shown to increase arterial compliance and outward hypertrophic remodeling. Therefore, we investigated the possibility that relaxin acts on its receptor, RXFP1, to mediate uterine artery compliance in late pregnancy and increase uterine blood flow velocity in rats. RXFP1 was predominantly localized to the tunica media vascular smooth muscle cells in the uterine artery, although receptors were also detected in endothelial cells. Highest expression of Rxfp1 in the uterine artery occurred in estrus and early pregnancy. Isolated uterine arteries from late pregnant rats treated with a monoclonal antibody against circulating relaxin (MCA1) had significantly increased vessel wall stiffness compared with controls, with no reduction in wall thickness. Chronic infusion of relaxin (4 μg/h, osmotic minipump) for 5 d in nonpregnant rats significantly increased uterine artery blood flow velocity. Overall, these data demonstrate a functional role for relaxin in mediating uterine artery compliance in pregnant rats, which may be necessary to maintain adequate uterine blood flow to the uterus and placenta.

    Myomas represent a large part of benign gynecological pathology, widely spread in fertile female population. First step to diagnose fibroids is ultrasound (US) that can be 2-dimensional (2D), 3-dimensional (3D), Color Doppler (CD) and sonohysterography (SHG). This review develops according to MUSA's sonographic features (Morphological Uterus Sonographic Assessment). One of the main topic of interest for ultrasonographer today is endo/myometrial junctional zone (JZ), because it may be useful to discern a diagnosis of myoma and adenomyosis. Another important aspect of ultrasound is the analysis of vascularization in front of a uterine lesion. Indeed, vascular pattern can be used to make differential diagnosis between myoma-adenomyosis and leiomyosarcomas. Myomas should be described accurately according to sonographic guidelines. Sonographic features correlated with symptoms should guide an appropriate surgical or medical treatment. PMID:27014801

    Metritis and endometritis commonly occur in dairy cows after calving. Although numerous studies have been performed to identify the causative pathogens, a complete overview has not been done. Metagenomic studies have analyzed the bacterial populations of uterine flush samples from postpartum (pp) dairy cows, but the microbiota in the uterine luminal fluid may differ from the microbiota of the endometrium itself, and important putative pathogens may have been overlooked. In the present study, we compared the microbiota of the uterine lumen and the endometrium of healthy, metritic, and endometritic cows. Samples were collected from 68 Holstein dairy cows at 1, 4, and 7 weeks pp, and the data were analyzed by deep sequencing of the V1 and V2 hypervariable regions of the 16S ribosomal RNA gene. The results showed that Porphyromonadaceae, Fusobacteriaceae, Leptotrichiaceae, and Mycoplasmataceae may be associated with uterine disease. The microbiota of the uterine flush samples and the endometrial biopsies were correlated, but the microbiota of the biopsies was more diverse. Fusobacteriaceae and Leptotrichiaceae were not observed in the biopsies at week 7, whereas they accounted for 20% and 13%, respectively, of the bacterial populations in the flush samples. The Mycoplasmataceae family was observed in much higher quantity in the flush samples than in the biopsies of the endometritis groups at weeks 4 and 7. Our findings support the observations of previous metagenomic studies and illustrate the importance of including endometrial biopsies to obtain more detailed knowledge of the pp uterine microbiota.

  13. Uterine Artery Embolization to Treat Uterine Adenomyosis with or without Uterine Leiomyomata: Results of Symptom Control and Health-Related Quality of Life 40 Months after Treatment

    International Nuclear Information System (INIS)

    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.

  16. Clinical application of uterine artery embolization in treating uterine scar pregnancy

    International Nuclear Information System (INIS)

    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)

    Uterine vascular elastosis in mares is characterized by degeneration of uterine vasculature through thickening of the elastin layers. Factors commonly associated with this degeneration include age, parity, and chronic uterine endometritis. Affected mares have also been shown to exhibit decreases in uterine blood flow and perfusion of the uterus. Due to the increased thickness of the elastin layers, we hypothesize that vasodilatation of the uterine vasculature is also impaired. To test the functionality of these vessels, we evaluated the vasodilatory effects of estradiol on the uterine vascular bed in mares with normal vasculature and mares with severe elastosis. Both groups were tested in estrus and diestrus. Fluorescent microspheres were used to determine basal blood perfusion, followed by the intravenous administration of 1.0 μg/kg of 17β-estradiol. After 90 min, perfusion was measured once again to determine the vascular response to estradiol. Control mares in estrus displayed a significant increase in total uterine blood flow after the administration of estradiol when compared to baseline levels. No other group had a significant increase in total blood flow and perfusion after estradiol administration. The administration of estradiol in control mares induced regional increases in perfusion in the uterine horns and uterine body during estrus and only in the uterine horns during diestrus. Mares affected by elastosis exhibited no regional differences in perfusion levels post-estradiol administration. The difference in the vasodilatory response induced by estradiol between reproductively healthy mares and mares affected with elastosis indicates that the functionality of the affected vessels is compromised.

    Ultrasonography is a safe and efficient technique for monitoring fetal development and viability. One of the most important and widely used parameters to verify fetal viability is the fetal heart rate (HR). In human medicine, the fetal HR normally oscillates during labor in transient accelerations and decelerations associated with uterine contractions. The present study investigated whether these variations also occur in canine fetuses and its relationship to parturition. A cohort study was conducted in 15 pregnant bitches undergoing two-dimensional high-resolution ultrasonographic examination during the 8th and 9th week of gestation. Fetal HR was assessed in M-mode for 5 minutes in each fetus in all bitches. In addition, the bitches were monitored for clinical signs of imminent parturition. Associations between the HR, antepartum time, and delivery characteristics were evaluated with a Poisson regression model. Fetal HR acceleration and deceleration occurred in canine fetuses and predicted the optimal time of parturition. These findings can help veterinarians and sonographers better understand this phenomenon in canine fetuses. PMID:24888684

Various conservative and surgical therapies have been outlined in the literature for the management of uterine inversions. Case. We present a case of a chronic, recurrent uterine inversion, which was diagnosed following spontaneous vaginal delivery and recurred seven weeks later. The uterine inversion was likely due to a leiomyoma. This late-presenting, chronic, recurring uterine inversion was treated with a vaginal hysterectomy. Conclusion. Uterine inversions can occur in both acute and chronic phases. Persistent vaginal bleeding with the appearance of a prolapsing fibroid should prompt further investigation for uterine inversion and may require surgical therapy. A vaginal hysterectomy may be an appropriate management option in select populations and may be considered in women who do not desire to maintain reproductive function.

    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.

    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.

    Host-microbe interactions may play a fundamental role in the pathogenesis of atopic dermatitis, a chronic relapsing inflammatory skin disorder characterized by universal colonization with Staphylococcus species. To examine the relationship between epidermal barrier function and the cutaneous microbiota in atopic dermatitis, this study used a spontaneous model of canine atopic dermatitis. In a cohort of 14 dogs with canine atopic dermatitis, the skin microbiota were longitudinally evaluated with parallel assessment of skin barrier function at disease flare, during antimicrobial therapy, and post-therapy. Sequencing of the bacterial 16S ribosomal RNA gene showed decreased bacterial diversity and increased proportions of Staphylococcus (S. pseudintermedius in particular) and Corynebacterium species compared with a cohort of healthy control dogs (n = 16). Treatment restored bacterial diversity with decreased proportions of Staphylococcus species, concurrent with decreased canine atopic dermatitis severity. Skin barrier function, as measured by corneometry, pH, and transepidermal water loss also normalized with treatment. Bacterial diversity correlated with transepidermal water loss and pH level but not with corneometry results. These findings provide insights into the relationship between the cutaneous microbiome and skin barrier function in atopic dermatitis, show the impact of antimicrobial therapy on the skin microbiome, and highlight the utility of canine atopic dermatitis as a spontaneous nonrodent model of atopic dermatitis.

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)

    Background. It is widely assumed that the uterine cavity in non-pregnant women is physiologically sterile, also as a premise to the long-held view that human infants develop in a sterile uterine environment, though likely reflecting under-appraisal of the extent of the human bacterial metacommunity. In an exploratory study, we aimed to investigate the putative presence of a uterine microbiome in a selected series of non-pregnant women through deep sequencing of the V1-2 hypervariable region o...

    A fraction of cells residing in the uterine endometrium exhibit functional pluripotent potential, allowing them to be classified as adult stem cells. While the physiological relevance of this cell population is mostly conjectural at this juncture, uterine endometrial stem cells (UESC's) may underline pathogenesis of certain common gynecological disorders, such as endometriosis and adenomyosis. The ease of access and harvesting of UESC's and the diverse differentiation potential of this cell population has identified the uterine endometrium as a valuable source of autologous stem cells that can be harnessed through judicious application of principals of regenerative medicine. This mini review offers a glimpse into the journey, and an introduction to the spectrum of disorders that UESC's have the potential of impacting. PMID:26297687

  11. Exploring preterm birth as a polymicrobial disease: An overview of the uterine microbiome.

    2014-11-01

    Full Text Available Infection is the leading cause of preterm birth. A focus of many studies over the past decade has been to characterise microorganisms present in the uterine cavity and document any association with negative pregnancy outcome. A range of techniques have been used to achieve this, including microbiological culture and targeted polymerase chain reaction assays, and more recently, microbiome-level analyses involving either conserved, phylogenetically informative genes such as the bacterial 16S rRNA gene or whole shotgun metagenomic sequencing. These studies have contributed vast amounts of data towards characterisation of the uterine microbiome, specifically that present in the amniotic fluid, fetal membranes and placenta. However, an overwhelming emphasis has been placed on the bacterial microbiome, with far less data produced on the viral and fungal/yeast microbiomes. With numerous studies now referring to preterm birth as a polymicrobial condition, there is the need to investigate the role of viruses and fungi in more detail and in particular, look for associations between colonisation with these microorganisms and bacteria in the same samples. Although the major pathway by which microorganisms are believed to colonise the uterine cavity is vertical ascension from the vagina, numerous studies are now emerging suggesting haematogenous transfer of oral microbiota to the uterine cavity. Evidence of this has been produced in mouse models and although DNA-based evidence in humans appears convincing in some aspects, use of methodologies that only detect viable cells as opposed to lysed cells and extracellular DNA are needed to clarify this. Such techniques as RNA analyses and viability PCR are likely to play key roles in the clinical translation of future microbiome-based data, particularly in confined environments such as the uterus, as detection of viable cells plays a key role in diagnosis and treatment of infection.

    CT findings in 37 cases with pathological diagnosis of uterine adenomyosis were reviewed retrospectively. The attenuation coefficient of adenomyosis is almost the same as normal parenchyma on both plain and enhanced CT. The margin was obscure except for one case. In focal type, deviation of the endometrium and deformity of the uterus may be a clue to the detection of adenomyosis. But differential diagnosis of adenomyosis from leiomyoma with ill-defined margin was very difficult. In diffuse type, the uterine body is swollen without deviation of the endometrium. This type can be diagnosed if the endometrium is identified clearly. (author)

    Obstructive jaundice as an initial manifestation of uterine cancer is extremely rare. We present a case of a 72-year-old female who presented with obstructive jaundice, supposedly for pancreatic cancer. After detailed diagnostic investigation, the cause of the jaundice was attributed to a metastatic compression of the common bile duct, from the primary neoplasm of the uterus. This case highlights the importance of including uterine cancer in the differential diagnosis of woman presenting with obstructive jaundice, even though it is very rare. PMID:27462179

    Adenovirus based vectors are very attractive candidates for vaccination purposes as they induce in mammalian hosts potent humoral, mucosal and cellular immune responses to antigens encoded by the inserted genes. We have generated E1-deleted and replication-competent recombinant canine type-2 adenoviruses expressing the rabies virus glycoprotein (G). The effectiveness of both vectors to express a native G protein has been characterized in vitro in permissive cell lines. We compared the humoral and cellular immune responses induced in mice by intramuscular injection of the recombinant canine adenovirus vectors with those induced by a human (Ad5) E1-deleted virus expressing the same rabies G protein. Humoral responses specific to the adenoviruses or the rabies glycoprotein antigens were studied. The influence of the mouse strain was observed using replication-competent canine adenovirus. A high level of rabies neutralizing antibody was observed upon i.m. inoculation, and 100% of mice survived lethal challenge. These results are very promising in the perspective of oral vaccine for dog rabies control. PMID:18634509

    2015-09-01

    Full Text Available Uterine leiomyoma (UL is common benign tumor of female genitals. Uterine artery embolization (UAE is widely used method of organ-sparing UL treatment. Safe ty of this procedure for future fertility and labor is controversial. We present a case of pregnancy in woman who previously underwent uterine artery embolization. During 12-months’ follow-up period patient periodically noted vaginal di¬scharge. No signs of UL have been found on ultrasound in 12 months of follow-up. Normal pregnancy occurred 1.5 years after UAE procedure which ended in normal labor without complications. Most authors report increased risk of pregnancy complications such as postpartum hemorrhage, preterm delivery, malpresentation after UAE. Our point of view is that a lot of pregnancy complications are possibly associated with persistence of necrotic leiomyoma tissue in uterine wall after UAE. Presented case allowed to draw preliminary conclusions that complete disappearance of UL nodule after UAE could improve pregnancy outcomes.

    International Nuclear Information System (INIS)

    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 (p0.05). 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

  8. MR Reproducibility in the Assessment of Uterine Fibroids for Patients Scheduled for Uterine Artery Embolization

    International Nuclear Information System (INIS)

    Magnetic resonance imaging (MRI) is increasingly applied in the evaluation of uterine fibroids. However, little is known about the reproducibility of MRI in the assessment of uterine fibroids. This study evaluates the inter- and intraobserver variation in the assessment of the uterine fibroids and concomitant adenomyosis in women scheduled for uterine artery embolization (UAE). Forty patients (mean age: 44.5 years) with symptomatic uterine fibroids who were scheduled for UAE underwent T1- and T2-weighted MRI. To study inter- and intraobserver agreement 40 MR images were evaluated independently by two observers and reevaluated by both observers 4 months later. Inter- and intraobserver agreement was calculated using Cohen's κ statistic and intraclass correlation coefficient for categorical and continuous variables, respectively. Inter-observer agreement for uterine volumes (κ = 0.99, p 1- and T2-weighted signal intensity of the dominant fibroid there was good agreement between the observers (87%; 95% CI, 71.9%-95.6%) and the intraobserver agreement was good for observer A (95%; 95% CI, 83.1%-99.4%) and moderate for observer B (κ = 0.47). The interobserver agreement with respect to the presence of adenomyosis was good (κ = 0.73, p < 0.0001), while both intraobserver agreements were fair to moderate (observer A, κ = 0.55, p = 0.0003; and observer B, κ = 0.66, p < 0.0001). In conclusion, MRI criteria used for the selection of suitable UAE patients show good inter- and intraobserver reproducibility

    Full Text Available Uterine neoplasms composed of an admixture of smooth muscle and adipose tissue are rare and have been designated as lipoleiomyomas. The origin of this tumor is stil controversial and it has not been sufficiently studied. The aim of our study was to investigate the immunohistochemical phenotype of fat cells in uterine lipoleiomyomas so as to clarify their origin. Archived tissue samples of 10 uterine lipoleiomyomas were selected and analyzed immunohistochemically for vimentin, desmin, and HMB-45 expression. The patients ranged from 31 to 63 years of age (mean age 53.5±9.9. Seven tumors which affected the uterine corpus, showed intramural location; while two cases were subserosal, and one was in the cervix. All tumors were constituted by irregular bundles of smooth cells and mature large adipose cells. The amount of adipose component varied from 5 to 95% of the tumor mass. Cytological atypia and necrosis were not seen. Immunohistochemical investigations revealed obvious reactivity to vimentin and desmin in perivascular immature mesencyhmal cells and tumoral smooth muscle cells. Adipose cells in the tumors demonstrated uniform vimentin expression and inconsistent desmin immunoreactivity. All adipose cells were negative for HMB-45 antigen. However, HMB-45 antigen was weakly positive in spindle shaped tumor cells of two cases. In our study, the immunohistochemical findings suggest a complex histogenesis for these tumors, which may arise from perivascular immature mesencyhmal cells or direct transformation of smooth muscle cells into adipocytes by means of progressive intracellular storage of lipids.

    Campylobacter jejuni is the most important cause of bacterial gastroenteritis in humans. It is a commensal in many wild and domestic animals, including dogs. Whereas genotypes of human and chicken C. jejuni isolates have been described in some detail, only little information on canine C. jejuni genotypes is available. To gain more information on genotypes of canine C. jejuni and their zoonotic potential, isolates from routine diagnostics of diarrheic dogs as well as isolates of a prevalence study in non-diarrheic dogs were analyzed. Prevalence of thermophilic Campylobacter among non-diarrheic dogs was 6.3% for C. jejuni, 5.9% for Campylobacter upsaliensis and 0.7% for Campylobacter coli. The C. jejuni isolates were genotyped by multi locus sequence typing (MLST) and flaB typing. Resistance to macrolides and quinolones was genetically determined in parallel. Within the 134 genotyped C. jejuni isolates 57 different sequence types (ST) were found. Five STs were previously unrecognized. The most common STs were ST-48 (11.2%), ST-45 (10.5%) and ST-21 (6.0%). Whereas no macrolide resistance was found, 28 isolates (20.9%) were resistant to quinolones. ST-45 was significantly more prevalent in diarrheic than in non-diarrheic dogs. Within the common time frame of isolation 94% of the canine isolates had a ST that was also found in human clinical isolates. In conclusion, prevalence of C. jejuni in Swiss dogs is low but there is a large genetic overlap between dog and human isolates. Given the close contact between human and dogs, the latter should not be ignored as a potential source of human campylobacteriosis. PMID:24210812

Uterine swab samples were collected with double guarded swabs and transported overnight before being cultured. The Minimum Inhibitory Concentrations (MIC was determined for a panel of antimicrobials. From 152 of the 239 mares at least one bacterial species was isolated, most frequently E. coli (104 isolates, β-haemolytic streptococci (31 and fungi (16. β-haemolytic streptococci were more frequently (p E. coli (p β-haemolytic streptococcal isolates some resistance was noted for 4 of 11 tested antibiotics, however, all isolates were susceptible to the widely used penicillin G. Among E. coli isolates enrofloxacin was the only of the 10 tested antibiotics for which no resistance was noted. Resistance was most commonly noted to cephalothin (39% of the isolates, streptomycin (22%, trimethoprim/sulphamethoxazole (15% and ampicillin (11%. In conclusion, we show that both E. coli and β-haemolytic streptococci are frequently associated with fertility problems in mares and that antimicrobial resistance is a common feature of E. coli but also recognised for β-haemolytic streptococcal uterine isolates.

    Full Text Available Systemic and local factors can modify the eruption time of teeth. Generalized eruption time changes could be due to some systemic diseases like hyperthyroidism, hypophosphatasia, precocious puberty, Proteus syndrome, etc. Localized early eruption of permanent teeth could be due to early extraction of deciduous teeth. Presented here is an extremely rare case of early eruption of permanent canines in a 7-year old female child. Though the number of such cases is very limited, the clinician should poses adequate knowledge and keeps an open eye to identify such cases.

  18. Alpha-1-antitrypsin studies: canine serum and canine surfactant protein

    International Nuclear Information System (INIS)

    Canine serum alpha-1-antitrypsin was isolated by gel filtration and affinity chromatography and characterized by polyacrylamide gel electrophoresis and immunoelectrophoresis. Measurement of the trypsin inhibitory capacity of the separated protein indicated a ninefold concentration of functional trypsin inhibitor during the isolation procedure. Electrophoresis demonstrated the presence of a single protein with alpha-globulin mobility and a molecular weight near that of human alpha-1-antitrypsin. The trypsin inhibitory capacity of pulmonary surfactant protein from five Beagle dogs was measured, related to total surfactant protein concentration, and compared with similar measurements on whole serum from the same animals. Results indicated a variable concentration of trypsin inhibitor in the canine pulmonary surfactant protein. However, the concentration in the surfactant protein was always significantly higher than that in the corresponding serum sample. Preliminary experiments designed to separate the trypsin inhibitory fraction(s) from the other surfactant proteins by gel filtration chromatography indicated that the trypsin inhibitor was probably a single protein with a molecular weight near that of alpha-1-antitrypsin.

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.

    Uterine contamination with bacteria is ubiquitous in the postpartum dairy cow. Nearly one-half of all postpartum dairy cows develop clinical disease resulting in metritis and endometritis, which cause depressed milk production and infertility. The causative links between uterine infection and infertility include a hostile uterine environment, disrupted endocrine signaling, and perturbations in ovarian function and oocyte development. In this review we consider the various mechanisms linking uterine infection with infertility in the dairy cow, specifically 1) innate immune signaling in the endometrium, 2) alteration in endocrine signaling in response to infectious agents, and 3) impacts of infection on ovarian function, oocyte development, and follicular development. Normal ovarian follicular and oocyte development requires a series of temporally and spatially orchestrated events; however, several of the cellular pathways required for ovarian function are also used during the innate immune response to bacterial pathogens. We propose that activation of cellular pathways during this immune response has a negative impact on ovarian physiology, which is manifest as infertility detected after the clearance of the bacteria. This review highlights how new insights into infection and immunity in cattle are linked to infertility. PMID:26020298

    Full Text Available Ureaplasma diversum is an opportunistic pathogen associated with uterine inflammation, impaired embryo implantation, infertility, abortions, premature birth of calves and neonatal pneumonia in cattle. It has been suggested that the intra-uterine infection by Ureaplasma diversum can cause vascular changes that hinder the success of pregnancy. Thus, the aim of this study was to evaluate the changes of intrauterine site of A/J mice in estrus or proestrus phase inoculated with Ureaplasma diversum. The infection was monitored at 24, 48 and 72 hours by the PCR methodology to detect the Ureaplasma in the inoculation site and the profile of circulating blood cells. Morphological changes, intensity of inflammation and the production of cytokines were compared. The infected mice showed local inflammation through the production of IFN-γ and TNF-α. Ureaplasma diversum infections in the reproductive tract of studied mice seemed to be associated with the production of pro-inflammatory cytokines in uterine parenchyma. The levels of TNF-α of infected mice were dependent on the bacterial load of inoculated Ureaplasma. Uterine experimental infections by Ureaplasma diversum have not been mentioned yet and herein we presented the first report of an intrauterine infection model in mice.

  3. Uterine artery chemoembolization: its application in treating cervical pregnancy

    International Nuclear Information System (INIS)

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

  4. The Epidemiology and Genetics of Uterine Leiomyoma.

    2016-07-01

    Uterine leiomyomas (fibroids) are the most common benign neoplasms in premenopausal women, which confer significant morbidity during the reproductive years and represent a significant public health issue. The incidence of fibroids has been associated with African-American race, early onset of menarche, early parity, and environmental/dietary exposures. These sex steroid-responsive uterine tumors are characterized by de novo transformation of the myometrium into fibroids via excessive formation of the extracellular matrix (ECM). Cytogenic anomalies, mutations in mediator complex subunit 12 (MED 12), and aberrant DNA methylation/demethylation have been observed, but have not been reported as direct mediators of fibroid development. Recent advances in epigenetics have implied a functional role of G protein-coupled receptor 10 (GPR10) overexpression and irregular microRNA expression in the pathobiology of fibroids that require future investigation. Herein, the impact of epidemiologic and genetic factors on the incidence and development of fibroids is reviewed. PMID:26725703

  5. Hormones and pathogenesis of uterine fibroids.

    Science.gov (United States)

    Reis, Fernando M; Bloise, Enrrico; Ortiga-Carvalho, Tânia M

    2016-07-01

    The role of ovarian steroid hormones in the pathogenesis of uterine fibroids is supported by epidemiological, clinical, and experimental evidence. Estradiol and progesterone induce mature leiomyoma cells to release mitogenic stimuli to adjacent immature cells, thereby providing uterine leiomyoma with undifferentiated cells that are likely to support tumor growth. Progesterone action is required for the complete development and proliferation of leiomyoma cells, while estradiol predominantly increases tissue sensitivity to progesterone by increasing the availability of progesterone receptors (PRs). The selective estrogen receptor modulator (SERM) raloxifene and the selective PR modulators (SPRMs) mifepristone, asoprisnil, and ulipristal acetate have been shown in clinical trials to inhibit fibroid growth. The role of sex steroids is critical for leiomyoma development and maintenance, but a number of autocrine and paracrine messengers are involved in this process; hence, numerous pathways remain to be explored in therapeutic innovations for treating this common disease.

    2014-09-01

    Uterine fibroids (leiomyomata) are extremely common lesions that are associated with detrimental effects including infertility and abnormal uterine bleeding. Fibroids cause molecular changes at the level of endometrium. Abnormal regulation of growth factors and cytokines in fibroid cells may contribute to negative endometrial effects. Understanding of fibroid biology has greatly increased over the last decade. Although the current armamentarium of Food and Drug Administration-approved medical therapies is limited, there are medications approved for use in heavy menstrual bleeding that can be used for the medical management of fibroids. Emergence of the role of growth factors in pathophysiology of fibroids has led researchers to develop novel therapeutics. Despite advances in medical therapies, surgical management remains a mainstay of fibroid treatment. Destruction of fibroids by interventional radiological procedures provides other effective treatments. Further experimental studies and clinical trials are required to determine which therapies will provide the greatest benefits to patients with fibroids. PMID:24819877

    Full Text Available Introduction. Most common metastasis sites of breast cancer are the lungs, bones, liver, and brain, whereas uterine involvement by metastatic breast disease is rare. Metastatic carcinoma of the uterus usually originates from other genital sites, most commonly being from the ovaries. Invasive lobular carcinoma spreads to gynecologic organs more frequently than invasive ductal carcinoma. Case Report. A 57-year-old postmenopausal woman was diagnosed with breast carcinoma 2 years ago and modified radical mastectomy was performed. Pathological examination of tumor revealed invasive ductal carcinoma, stage IIIc. She presented with abdominal pain and distension. Diagnostic workup and gynecologic examination revealed lesions that caused diffuse thickening of the uterus wall. Endometrial sampling was performed for confirmation of the diagnosis. She underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. Breast carcinoma metastases in endometrium and myometrium were confirmed histopathologically and immunohistochemically. Conclusion. We herein report the first case of isolated uterine patient who had invasive ductal carcinoma of breast.

    2004-01-01

    This review begins with a brief commentary on the diversity of placentation mechanisms, and then goes on to examine the extensive alterations which occur in the plasma membrane of uterine epithelial cells during early pregnancy across species. Ultrastructural, biochemical and more general morphological data reveal that strikingly common phenomena occur in this plasma membrane during early pregnancy despite the diversity of placental types-from epitheliochorial to hemochorial, which ultimately form in different species. To encapsulate the concept that common morphological and molecular alterations occur across species, that they are found basolaterally as well as apically, and that moreover they are an ongoing process during much of early pregnancy, not just an event at the time attachment,brane during early pregnancy are key to uterine receptivity.

    In addition to surgical methods of treating uterine fibroids, numerous non-invasive treatments have been developed. Many of these involve the use of hyperthermia, the heating of tissue by a variety of methods. These include the use of lasers, radiofrequency, microwave energy and high intensity focused ultrasound, guided by both ultrasound and magnetic resonance imaging. In this review we examine the technology behind these treatment modalities and review the current evidence for their use. PMID:25815582

    2009-07-01

    Canine tooth size reduction and the associated reduction in canine dimorphism is a basal hominin character that also provides important evidence for models of behavioral evolution. Two specimens of Australopithecus anamensis (KNM-KP 29287 and KNM-KP 29283) that do not preserve the canine crown, but do preserve the root or alveolus, appear to suggest that canine size variation and canine dimorphism in this species may have been greater than in other hominins. We evaluate canine root and crown dimensions in a series of extant hominoids, and estimate canine crown height in Australopithecus afarensis and A. anamensis. Our results demonstrate that it is possible to generate estimates of canine crown height from basal canine crown and root dimensions with a moderate degree of accuracy. Estimates of maxillary canine crown size for A. anamensis are slightly larger than those of A. afarensis, and are approximately the same size as canines of modern female chimpanzees. Estimated mandibular canine crown height is very similar in the two species. Variation within the A. anamensis sample of estimated canine crown heights is similar to that of modern humans, suggesting a low degree of sexual dimorphism. Inclusion of estimates for KNM-KP 29287 and KNM-KP 29283 does not substantially increase either the estimate of overall canine size or variation for A. anamensis. PMID:19482334

    International Nuclear Information System (INIS)

    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)

    International Nuclear Information System (INIS)

    Objective: To analysis the characteristics and clinical features of uterine neoplasms developed after radiation therapy for cervical carcinoma. Methods: The clinical data of 47 patients of uterine neoplasm developed following radiotherapy for uterine cervical carcinoma were retrospectively reviewed. Results: The median age on diagnosis of uterine neoplasms was 62 years (range 38-77), and the median latency from the initial therapy to the development of uterine neoplasm was 14 years (range 5-35). Thirty of 47 patients had endometrial carcinoma, of which 3 were uterine papillary serous carcinoma(UPSC). Seventeen of 47 patients had uterine sarcoma, all of which were carcinosarcoma. The distribution by stage, grade, and histology of 30 patients with endometrial carcinoma was: stage Ib, 1 patient; stage Ic, 2 patients; stage II, 6; stage III a, 4; stage III b, 2; stage III c, 11; stage IV, 4; grade 1, 2 patients; grade 2, 9; grade 3 (include 3 UPSC patients), 17; unknown grade, 2; endometriod, 27; UPSC, 3. Seven of 30 patients with en- dometrial carcinoma deleloped recurrence, at median time of 24 months. Their median survival time was 26 m. The overall 3- and 5-year survival rate was 60% and 38%, respectively. Of the 17 patients with uterine sarcoma, the median survival was 10 months. Six patients developed recurrence, at a median time of 9 months, and their median survival was 6 months. The overall 3- and 5-year survival rate was 12% and 0, respectively. Conclnsions: The main uterine neoplasm developed after radiotherapy for uterine cervical carcinoma is endometrial carcinoma, of which there is a preponderance of high-risk histological subtype and poor prognosis. Most of the uterine sarcoma which occur following radiation therapy for uterine cervical carcinoma is carcinosarcoma and its prognosis is very poor. (authors)

    2009-12-01

    To explore the potential mechanism of how uterine innervations would affect the uterine mast cell (MC) population and functions during the periimplantation. We herein first examined the consequence of uterine neurectomy on embryo implantation events. We observed that amputation of autonomic nerves innervating the uterus led to on-time implantation failure in rats. Exploiting MC culture and ELISA approaches, we then further analyzed the effect of neurectomy on cellular histamine levels and its release from uterine MCs, to elucidate the relation of the autonomic nerves and local cellular immunity in the uterine during early pregnancy. We observed that disconnection of autonomic nerve innervation significantly increased the population of uterine MCs. Most interestingly, these increased number of uterine MCs in neuroectomized rats contained a much reduced cellular level of histamine. Our subsequent challenge experiments revealed that uterine MCs in nerve amputated rats exhibited enhanced histamine releasing rate in response to substance P and antiIgE, suggesting loss of nerve innervation in the uterus not only increases the population of uterine MCs, but also facilitates the release of histamine from MCs, thus subsequently interfere with the normal implantation process. Collectively, our findings provide a new line of evidence supporting the concept that immune-neuro-endocrine network plays important role during pregnancy establishment and maintenance.

    Full Text Available Aim: The aim of this study was to perform a clinical and statistical research on permanent impacted canine patients among those with dental impaction referred to and treated at the Oral and Maxillo-Facial Surgery Clinic of Tîrgu Mureș, over a four years period (2009-2012. Materials and methods: The study included 858 patients having dental impaction, and upon clinical records, different parameters, like frequency, gender, age, quadrant involvement, patient residence, associated complications, referring specialist and type of treatment, related to canine impaction, were assessed. Results: The study revealed: about 10% frequency of canine impaction among dental impactions; more frequent in women, in the first quadrant (tooth 13; most cases diagnosed between the age of 10-19 years; patients under 20 were referred by an orthodontist, those over 20 by a dentist; surgical exposure was more often performed than odontectomy. Conclusions: Canine impaction is the second-most frequent dental impaction in dental arch after third molars; it occurs especially in women. Due to its important role, canine recovery within dental arch is a goal to be achieved, whenever possible. Therefore, diagnose and treatment of canine impaction requires an interdisciplinary approach (surgical and orthodontic

    Intestinal nematodes affecting dogs, i.e. roundworms, hookworms and whipworms, have a relevant health-risk impact for animals and, for most of them, for human beings. Both dogs and humans are typically infected by ingesting infective stages, (i.e. larvated eggs or larvae) present in the environment. The existence of a high rate of soil and grass contamination with infective parasitic elements has been demonstrated worldwide in leisure, recreational, public and urban areas, i.e. parks, green areas, bicycle paths, city squares, playgrounds, sandpits, beaches. This review discusses the epidemiological and sanitary importance of faecal pollution with canine intestinal parasites in urban environments and the integrated approaches useful to minimize the risk of infection in different settings.

    Neya Systems, LLC competed in the CANINE program sponsored by the U.S. Army Tank Automotive Research Development and Engineering Center (TARDEC) which culminated in a competition held at Fort Benning as part of the 2012 Robotics Rodeo. As part of this program, we developed a robot with the capability to learn and recognize the appearance of target objects, conduct an area search amid distractor objects and obstacles, and relocate the target object in the same way that Mine dogs and Sentry dogs are used within military contexts for exploration and threat detection. Neya teamed with the Robotics Institute at Carnegie Mellon University to develop vision-based solutions for probabilistic target learning and recognition. In addition, we used a Mission Planning and Management System (MPMS) to orchestrate complex search and retrieval tasks using a general set of modular autonomous services relating to robot mobility, perception and grasping.

    Full Text Available The oral microbiome, which is closely associated with many diseases, and the resident pathogenic oral bacteria, which can be transferred by close physical contact, are important public health considerations. Although the dog is the most common companion animal, the composition of the canine oral microbiome, which may include human pathogenic bacteria, and its relationship with that of their owners are unclear. In this study, 16S rDNA pyrosequencing was used to compare the oral microbiomes of 10 dogs and their owners and to identify zoonotic pathogens. Pyrosequencing revealed 246 operational taxonomic units in the 10 samples, representing 57 genera from eight bacterial phyla. Firmicutes (57.6%, Proteobacteria (21.6%, Bacteroidetes (9.8%, Actinobacteria (7.1%, and Fusobacteria (3.9% were the predominant phyla in the human oral samples, whereas Proteobacteria (25.7%, Actinobacteria (21%, Bacteroidetes (19.7%, Firmicutes (19.3%, and Fusobacteria (12.3% were predominant in the canine oral samples. The predominant genera in the human samples were Streptococcus (43.9%, Neisseria (10.3%, Haemophilus (9.6%, Prevotella (8.4%, and Veillonella (8.1%, whereas the predominant genera in the canine samples were Actinomyces (17.2%, Unknown (16.8, Porphyromonas (14.8, Fusobacterium (11.8, and Neisseria (7.2%. The oral microbiomes of dogs and their owners were appreciably different, and similarity in the microbiomes of canines and their owners was not correlated with residing in the same household. Oral-to-oral transfer of Neisseria shayeganii, Porphyromonas canigingivalis, Tannerella forsythia, and Streptococcus minor from dogs to humans was suspected. The finding of potentially zoonotic and periodontopathic bacteria in the canine oral microbiome may be a public health concern.

    After parturition, uterine bacterial infections lead to inflammatory processes such as subclinical/clinical endometritis with high prevalence in dairy cows. Endometrial epithelial cells participate in this immune response with the production of pro-inflammatory factors. The objective of the present study was to evaluate the endometrial mRNA expression pattern of pro-inflammatory factors during a selected postpartum (pp) period. Dairy cows with three different uterine health conditions on days 24-30 pp (healthy: n = 11, subclinical endometritis: n = 10, clinical endometritis: n = 10) were sampled using the cytobrush technique. Subsequently, each cow was sampled 3 more times in weekly intervals (days 31-37 pp; days 38-44 pp; days 45-51 pp). Samples were subjected to mRNA analysis performed by RT-qPCR. Additionally, an analysis of cultivable bacteria was performed at the early/late stage of the selected puerperal period. mRNA expression of 16 candidate genes was analyzed by using two different approaches. The first approach referred to the initial grouping on days 24-30 pp to reveal long-term effects of the uterine health on the subsequent puerperal period. The second approach considered the current uterine health status at each sampling to elucidate the impact of different points in time. Long-term effects seem to appear for chemokines, prostacyclin synthase and prostaglandin D2 synthase. If related to the current uterine health, the majority of candidate genes were significantly higher expressed in endometritic cows on days 45-51 pp in contrast to earlier stages of the puerperium. Microbiological analysis revealed the significantly higher prevalence of Trueperella pyogenes findings in cows with clinical endometritis on days 24-30 pp, but no correlations were found on days 45-51 pp. In conclusion, a strong immune response to subclinical/clinical endometritis in the late puerperium may be related to the negative impact of these conditions on reproductive performance

  3. MR imaging features of the congenital uterine anomalies

    International Nuclear Information System (INIS)

    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

    Full Text Available Objectives : Endometriosis and uterine fibroids are common gynecological disorders in fertile women. It has been suggested that these two disorders may be associated with each other. In this study, we tested whether this connection exists. In addition, we wanted to evaluate whether they both affect fertility independently of each other. Materials and Methods : The prevalence of endometriosis and uterine fibroids was investigated in three groups of patients: Symptomatic patients requiring surgery either for endometriosis (n=182, or for uterine fibroids (n=240 and asymptomatic patients undergoing laparoscopic sterilization (n=183. The prevalences were examined in three age groups: 35-39 yrs, 40-44 yrs and ≥ 45 yrs. The significance of both diagnoses on fertility was assessed using logistic regression analysis. Results :Uterine fibroids were detected in 25.8% (47/182 of patients with endometriosis. Endometriosis was detected in 19.6% (47/240 of patients with uterine fibroids. 5.5% (10/183 women undergoing sterilization had endometriosis and 19.3% (17/183 had uterine fibroids. Both uterine fibroids and endometriosis were, independently of each other, related to subfertility (OR, 95% CI: 3.8, 2.3-6.5; 6.8, 4.0-11.6, respectively. Conclusions : The results suggest that symptomatic endometriosis appears together with symptomatic uterine fibroids. Both diseases seem to decrease female fertility independently of each other.

  7. Uterine arterial embolization for the treatment of adenomyosis

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical value of treatment by uterine arterial embolization on adenomyosis. Methods: Fifteen cases of adenomyosis were treated by uterine arterial embolization. The 3.0 F or 4.0 F Cobra catheter was placed separately into the both uterine arteries with polyvinyl alcohol foam particles (PVA) as the embolic agent. The patients were followed-up at 1, 3, 6 and 12 months postoperatively. Results: The menorrhagia was controlled and the symptoms of anemia were relieved in all the patients. The blood flow within the uterine foci decreased immediately after embolization shown on color Doppler flow imagings. Conclusions: Uterine arterial embolization is an effective and less invasive way to treat adenomyosis

    Carcinosarcoma arising from uterine adenomyosis is extremely rare. We encountered such a patient and herein provide a review of the literature. A 56-year-old woman was referred for a huge pelvic tumor, suspected to be an advanced uterine leiomyosarcoma. Intraoperative inspection revealed a mass, mainly located in the uterine myometrium, invading the uterine serosa. The tumor had previously spontaneously ruptured and disseminated to the pelvic cavity. Pathological and immunohistochemical examination revealed an infiltrative pattern of biphasic tumor cells composed of endometrioid adenocarcinoma and a nonepithelial component with rhabdomyosarcomatous differentiation. Benign endometrial glands with stromal cells were found adjacent to the area of the carcinosarcoma. The endometrium and both ovaries and fallopian tubes were microscopically free of tumor cells. The final diagnosis was heterologous type carcinosarcoma with rhabdomyosarcomatous differentiation, originating from uterine adenomyosis. PMID:26663238

    Uterine papillary serous carcinoma (UPSC) is an aggressive variant of endometrial cancer. Owing to its rarity, most clinicians are unfamiliar with the clinical aspects and management of UPSC. Furthermore, little prospective evidence exists regarding how best to treat this subset of patients. In anticipation of prospective clinical trials, this article summarizes the latest results of various clinical management options in the different substages of UPSC, with a special focus on the effects of cytoreductive surgery, comprehensive surgical staging and different adjuvant treatment options in relation to recurrence rate and survival outcome.

    2014-02-01

    Full Text Available Domestic dogs are common amongst communities in sub-Saharan Africa and may serve as important reservoirs for infectious agents that may cause diseases in wildlife. Two agents of concern are canine parvovirus (CPV and canine distemper virus (CDV, which may infect and cause disease in large carnivore species such as African wild dogs and African lions, respectively. The impact of domestic dogs and their diseases on wildlife conservation is increasing in Zimbabwe, necessitating thorough assessment and implementation of control measures. In this study, domestic dogs in north-western Zimbabwe were evaluated for antibodies to CDV, CPV, and canine adenovirus (CAV. These dogs were communal and had no vaccination history. Two hundred and twenty-five blood samples were collected and tested using a commercial enzyme-linked immunosorbent assay (ELISA for antibodies to CPV, CDV, and CAV. Of these dogs, 75 (34% had detectable antibodies to CDV, whilst 191 (84% had antibodies to CPV. Antibodies to canine adenovirus were present in 28 (13% dogs. Canine parvovirus had high prevalence in all six geographic areas tested. These results indicate that CPV is circulating widely amongst domestic dogs in the region. In addition, CDV is present at high levels. Both pathogens can infect wildlife species. Efforts for conservation of large carnivores in Zimbabwe must address the role of domestic dogs in disease transmission.

  19. Development of the canine tooth in the beagle

    International Nuclear Information System (INIS)

    The growth of the crown and root in the canine tooth of beagle dogs were observed macroscopically and radiographically, and changes of occlusion with age were investigated. Completion of growth in the crown of the canine tooth was observed in both mandible and maxilla, and its eruption was accompanied by development of the dental root. The permanent canine erupted on the lingual side of deciduous canine in the mandible, and on the mesial side of the deciduous canine in the maxilla. Movement of the permanent canine to normal occlusal position(buccal direction in mandibular canine, and distal direction in maxillary canine)was followed by the loss of the deciduous canine. Coexistence of the permanent and deciduous canines occurred for about 2.4 weeks in the maxilla and about 1.4 weeks in the mandible, on average. Macroscopically, the growth of the permanent canine was completed by 33 weeks of age in the mandible and about 34 weeks of age in the maxilla. The mature root of the permanent canine was recognized radiographically at about 43 weeks of age in the mandible and 47 weeks of age in the maxilla

    Full Text Available Abstract Background Myocardial injury may contribute to unexpected deaths due to pyometra. To detect myocardial damage, measurement of cardiac troponin I (cTnI is currently the most sensitive and specific method. The aims of the present study were to evaluate presence of myocardial damage in canine pyometra by analysis of cTnI, to explore whether myocardial injury was associated with systemic inflammatory response syndrome (SIRS and to evaluate whether other clinical or laboratory parameters were associated with cTnI increase. Methods Preoperative plasma levels of cTnI were investigated in 58 female dogs with pyometra and 9 controls. The value of physical examination findings, haematological, serum biochemical and pro-inflammatory (CRP and TNF-α parameters as possible predictors of increased cTnI levels was also evaluated. Results Seven dogs with pyometra (12% and one control dog (11% had increased levels of cTnI. In the pyometra group, the levels ranged between 0.3–0.9 μg l-1 and in the control dog the level was 0.3 μg l-1. The cTnI levels did not differ significantly between the two groups. No cardiac abnormalities were evident on preoperative physical examinations. Four of the pyometra patients died within two weeks of surgery, of which two were examined post mortem. In one of these cases (later diagnosed with myocarditis and disseminated bacterial infection the cTnI levels increased from 0.9 μg l-1 preoperatively to 180 μg l-1 the following day when also heart arrhythmia was also detected. The other patient had cTnI levels of 0.7 μg l-1 with no detectable heart pathology post mortem. CTnI increase was not associated with presence of SIRS. There was a trend for the association of cTnI increase with increased mortality. No preoperative physical examination findings and few but unspecific laboratory parameters were associated with increased cTnI levels. Conclusion Increased cTnI levels were observed in 12% of the dogs with pyometra. The

  2. Canine hypothyroidism. A diagnostic challenge?

    International Nuclear Information System (INIS)

    Hypothyroidism is one of the most common endocrinopathies in dogs. Clinical symptoms and hematological and biochemical parameters lead to a first suspicion. To confirm diagnosis can be challenging, however. Determination of total serum T4 concentration is accepted as the primary screening test for the disease, and low serum T4 concentrations are intuitively suggestive of hypothyroidism. However it is well known that low T4 concentrations are frequently encountered in euthyroid dogs with various nonthyroidal diseases and in dogs receiving certain pharmacologic agents. Since assessment of endogenous TSH (canine TSH) using current canine TSH assays shows normal values in a high percentage of hypothyroid dogs (up to 40%), its diagnostic value is only limited. The TSH-stimulation test can still be recognized as the gold standard for the diagnosis of hypothyroidism in dogs. Determination of circulating T4 concentration before and 6 hours after the administration of exogenous TSH (recombinant human TSH, Thyrogen registered) provides an assessment of the functional reserve capacity of the thyroid gland with minimal change in post-TSH T4 concentration, compared with the basal concentration, expected in dogs with hypothyroidism. Also this test can be influenced by nonthyroidal illness and by medications known to affect thyroid function. This suppressing influence seems to be less pronounced using a higher dose of TSH. Therefore, to improve the discriminatory power of the TSH stimulation test to differentiate between euthyroid-sick and primary hypothyroidism, the higher dose should be used in cases in which testing cannot be delayed. More recently, ultrasonography and scintigraphy have been used for the diagnosis of primary hypothyroidism. Using ultrasonography, a sensitivity of 98% was reported if size and echogenicity of the gland were combined. However, specificity was as low as 77%. and care must be taken when measuring the gland because of a relatively high interobserver

    V. N. Zorina

    2015-06-01

    Full Text Available We studied blood contents of alpha-2-macroglobulin (α2-MG, pregnancy-associated alpha2-glycoprotein (PAG, and their immune complexes with IgG in healthy female controls, as well as in women with adenomyosis, females with uterine myoma (with or without proliferation, and in cases of a leiomyoma combined with adenomyosis. We found that the most pronounced reduction in α2-MG concentrations was observed in leiomyoma, but they were not decreased in a combination of myoma/ adenomyosis. The PAG levels, a known proliferation marker, have been shown to be increased only in the combined disorder. The amounts of immune complexes (α2-MG/IgG and PAG-IgG were more significantly increased in leiomyoma complicated by adenomyosis. Correlative interrelationships between the studied parameters differed between normal and pathological conditions. Given that α2-MG and PAG are immunoregulatory proteins being actively involved in proliferative and inflammatory processes, we may assume that they participate in pathogenesis of immune-related uterine diseases, and, especially, in combined disorders.

  4. Radiation-induced uterine changes: MR imaging

    International Nuclear Information System (INIS)

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

    2014-01-01

    A unicornuate uterus with a rudimentary horn is a uterine anomaly resulting from the incomplete development of one of the Müllerian ducts and an incomplete fusion with the contralateral side. Pregnancy in a rudimentary horn of the uterus is a rare clinical condition with a reported incidence of 1 in 100,000 to 140,000 pregnancies. Usually the diagnosis is missed and may present as an emergency with haemoperitoneum. The standard treatment is the surgical excision of the horn. A gravida 2, para 1 patient presented at 23 weeks’ gestation with fetal demise. Repeated failed attempts at induction of labour raised the suspicion of an abnormally located pregnancy which was confirmed by magnetic resonance imaging. She underwent a laparotomy with right rudimentary horn excision. The final diagnosis of a non-communicating rudimentary horn pregnancy was made intraoperatively and was confirmed by histopathology. This case highlights the importance of an early ultrasound in detecting uterine anomalies and the need for high clinical suspicion. PMID:24516746

    Fibroids, which are benign smooth-muscle tumors of clonal origin, are the most common gynecologic tumors occurring in about 20 to 25 % of women over 30 years of age. The most frequent symptoms are pelvic pain and heavy menstrual bleeding resulting in anemia. The role of fibroids in infertility remains debated but probably mostly related to submucosal location due to implantation impairment. Although most women are asymptomatic (80%), fibroids can have a considerable impact on quality of life. Considering this impact and the cost associated with their management, treatment of fibroids is a public health concern. Treatment options for symptomatic fibroids include medical, surgical and alternatives techniques. Medical management is mainly based on the use of progestogens, antifibrinolytics agents, non-steroidal anti-inflammatory drugs, Gonadotropin-releasing hormone analogs selective progesterone receptor modulators. Surgical management includes myomectomy (hysteroscopic, laparoscopic, minilaparoscopic or laparotomic) and hysterectomy. The choice of surgery depends on several factors: the number, topography and size of myomas, the age of the patient and her desire for fertility, treatment history and her desire to keep the uterus. Alternatives techniques to surgery are mainly based on the uterine artery embolization. The aim of this article is to provide evidence based recommendations for the management of uterine fibroids.

    Uterine artery adaptations during gestation facilitate increases in uterine blood flow and fetal growth. Hypothesis: Local expression and distribution of uterine artery connexins play roles in mediating in vivo gestational eNOS activation and Nitric Oxide production. We established an ovine model restricting pregnancy to a single uterine horn and measured uterine blood flow, uterine artery shear stress, connexins 37/43 and P635eNOS protein levels in uterine artery and systemic artery [Omental...

  8. Transmigration of mandibular canine – case report

    International Nuclear Information System (INIS)

    Transmigration is a phenomenon of movement of an unerupted tooth in the bone across the midline. This anomaly is not often found. Transmigration is more prevalent in females than in males, and more often encountered in the mandible than maxilla, it affects mostly canines. The aim of this study was to present a case report of a mandibular canine transmigration in a patient aged 12. Intraoral examination determined hypodontia of right second premolar and delayed eruption of left second premolar in maxilla, as well as persistent deciduous teeth: right second molar, left canine and second molar. The patient was referred for a Cone-Beam CT examination, which allowed precise visualization of the transmigrating canine as well as ruled out resorption of roots of mandibular incisors. The treatment with a maxillary fixed orthodontic appliance was finished after obtaining a satisfactory result. Proper alignment of the incisors in the anterior-posterior plane and correct midline position were accepted by the patient. Transmigrating canine after consultation with the surgeon was designed to further radiological observation

    To investigate canine kobuvirus (CaKoV) infection, fecal samples (n = 59) were collected from dogs with or without diarrhea (n = 21 and 38, respectively) in the Republic of Korea (ROK) in 2012. CaKoV infection was detected in four diarrheic samples (19.0 %) and five non-diarrheic samples (13.2 %). All CaKoV-positive dogs with diarrhea were found to be infected in mixed infections with canine distemper virus and canine parvovirus or canine adenovirus. There was no significant difference in the prevalence of CaKoV in dogs with and without diarrhea. By phylogenetic analysis based on partial 3D genes and complete genome sequences, the Korean isolates were found to be closely related to each other regardless of whether they were associated with diarrhea, and to the canine kobuviruses identified in the USA and UK. This study supports the conclusion that CaKoVs from different countries are not restricted geographically and belong to a single lineage. PMID:24906525

  10. Uterine fibroid embolization: Is there a role?

    International Nuclear Information System (INIS)

    We present a case of uterine fibroid embolization (UFE) in Salmanya Medical Complex, Bahrain as a primary theraputic option for a selected case symptomatic fibroid uterus.Within 6 weeks of UFE, this patient developed life threatening infection due to sloughing of the fibroid through the cervix but she conceived within 11-months of the procedure and delivered normally at term. As this patient developed life threatening infection, the author is left with the predicament whether to try it again or not in the next selected case. Our patient was a 20-year-old, nulliparous girl who had fibroid uterus extending 2 fingers above the umbilicus. Ultrasound and computed tomography confirmed a large intramural posterior wall fibroid uterus measuring 17 x 15 cms Uterine fibroid embolization was carried out by single puncture using 700 polyvinyl alcohol particles lodged permanently inside both the uterine arteries to block or damp the flow of the blood through these vessels. On 6th week, she had vaginal myomectomy for sloughing of submucous fibroid through the cervix. (Figure 1) Postoperatively, she showed immediate improvement. She conceived after 11-months of treatment and pregnancy till normal delivery was uneventful. Patients who have had fibroid embolization have become pregnant as in our patient, after 11-months of embolization. Bradley et al4 described a woman who conceived immediately after the procedure. Ravina et al1 also reported a successful twin pregnancy in his patients. There have been no studies that define the incidence of pregnancy after the procedure and further studies are necessary to delineate the impact of UFE on fertility. Many gynecologists consider UFE as safe, exciting, promising, minimally invasive and highly effective non surgical primary treatment for symptomatic fibroid uterus. In spite of this, patient should me made aware of the limitations of the treatment and she should recognize that complications of the procedure may lead to hysterectomy. As

  11. The application of uterine artery embolization for the treatment of uterine scar pregnancy after cesarean section

    International Nuclear Information System (INIS)

    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

  12. Bacterial carbonatogenesis

    International Nuclear Information System (INIS)

    Several series of experiments in the laboratory as well as in natural conditions teach that the production of carbonate particles by heterotrophic bacteria follows different ways. The 'passive' carbonatogenesis is generated by modifications of the medium that lead to the accumulation of carbonate and bicarbonate ions and to the precipitation of solid particles. The 'active' carbonatogenesis is independent of the metabolic pathways. The carbonate particles are produced by ionic exchanges through the cell membrane following still poorly known mechanisms. Carbonatogenesis appears to be the response of heterotrophic bacterial communities to an enrichment of the milieu in organic matter. The active carbonatogenesis seems to start first. It is followed by the passive one which induces the growth of initially produced particles. The yield of heterotrophic bacterial carbonatogenesis and the amounts of solid carbonates production by bacteria are potentially very high as compared to autotrophic or chemical sedimentation from marine, paralic or continental waters. Furthermore, the bacterial processes are environmentally very ubiquitous; they just require organic matter enrichment. Thus, apart from purely evaporite and autotrophic ones, all Ca and/or Mg carbonates must be considered as from heterotrophic bacterial origin. By the way, the carbon of carbonates comes from primary organic matter. Such considerations ask questions about some interpretations from isotopic data on carbonates. Finally, bacterial heterotrophic carbonatogenesis appears as a fundamental phase in the relationships between atmosphere and lithosphere and in the geo-biological evolution of Earth. (author)

    Full Text Available Mammary tumours are the second most frequent neoplasia in dogs, mainly affecting older female patients. Approximately 50% of the mammary tumours are malignant with high percentage of mortality if not treated in time. The aim of this study was to analyze the data of canine patients with mammary tumours, to evaluate the type of tumours, as well as the relationship between tumour incidence and dogs’ age, reproductive cycle and sterilization. The survey was used to retrieve the information in the period of two years from the patient data base of the University Veterinary Hospital at the Faculty of Veterinary medicine in Skopje. Patients included in this survey were subjected to routine clinical investigation and additional laboratory tests (cytological examination, x-rays imaging, CBC and biochemical profile, histopathology of the tumor samples. Aged female patients (12 – 13 years are the most susceptible category for development of mammary tumours. The reproductive history showed that five of the patients with malignant mammary tumourshave never whelped and were not treated with any exogenous hormones. Malignant tumours (adenocarcinoma were diagnosed in 90% of the patients. Three patients died due to lung metastasis. Late diagnosis is one of the major problems that results in lethal outcome due to lung metastases. Since ovarian steroids play an important role in the aetiology, the most effective prevention of mammary tumoursis elective ovariectomy of the bitch at an early age.

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Objective: To evaluate the feasibility of transplanting composite mandibular allografts to repair large mandibular defects. Methods: Three composite mandibular transplantation models were established. The first model consisted of hemimandible with the attached teeth, muscle and skin, and oral mucosa. The second model was transplanted in the same way with the first one excluding oral mucosa and some teeth, and third one excluding the oral mucosa and all dental crowns. Fourteen transplanting operations were performed in canines. Cyclosporine A and methylprednisone were given for immunosuppression. Results: The composite mandibular organs had an effective and closed return circuit. Transplantation of vascularized allograft of mandibular compound organs was feasible. Two longest time survivors of 67 d and 76 d were in the third model group. Cyclosporine A was successful in suppressing rejection of transplanted composite allograft and prolonging survival time of transplantation models. Conclusions: The composite mandibular allografts were available with large block of living composite tissue,and helpful in restoration of appearance and function for severe mandibular defects.

    Cinnamon is a spice used by some populations as a traditional remedy to control blood pressure and thus hypertension. Cinnamon extract decreases contractility in some smooth muscles, but its effect on uterine smooth muscle is unknown. The aim of this study was to determine the physiological and pharmacological effects of cinnamon extract (CE) on the contractions of isolated rat uterine strips and to investigate its possible mechanism of action. Isolated longitudinal uterine strips were dissected from non-pregnant rats, mounted vertically in an organ bath chamber, and exposed to different concentrations of CE (10-20mg/mL). The effect of CE was investigated in the presence of each of the following solutions: 60mM KCl, 5nM oxytocin, and 1μM Bay K8644. CE significantly decreased the force of uterine contraction in a concentration-dependent manner and significantly attenuated the uterine contractions elicited by KCl and oxytocin. In addition, CE significantly decreased the contractile force elicited when L-type Ca(2+) channels were activated by Bay K8644. CE's major mechanism may be inhibition of L-type Ca(2+) channels, which limits calcium influx. These data demonstrate that CE can be a potent tocolytic that can decrease uterine activity regardless of how the force was produced, even when the uterus was stimulated by agonists. As a result, cinnamon may be used to alleviate menstrual pain associated with dysmenorrhoea or prevent unwanted uterine activity in early pregnancy. PMID:26952750

    Uterine clear cell carcinoma (UCC) and uterine papillary serous carcinoma (UPSC) are rare entities that differ in clinical behavior from endometrial adenocarcinoma. Compared with endometrioid adenocarcinoma, they more often metastasize early and more commonly in the upper abdomen including the omentum. Treatment programs of UCC and UPSC at different stages vary and range from no adjuvant therapy in stage Ia to a wide variety of chemotherapies and radiotherapies in more advanced stages. This study presents the outcome of 109 patients with UCC or UPSC treated according to essentially the same treatment program from May 1993 to December 2004. Most patients were treated with a simple hysterectomy with no further adjuvant treatment. In stage Ia, 2/46 patients died of their disease and amongst all the stages, 30/109 patients died of their disease. These survival outcomes are comparable to or better than those presented previously. PMID:20944161

    Full Text Available Cancer is the leading cause of disease-related death in companion animals such as dogs and cats. Despite recent progress in the diagnosis and treatment of advanced canine and feline cancer, overall patient treatment outcome has not been substantially improved. Virotherapy using oncolytic viruses is one promising new strategy for cancer therapy. Oncolytic viruses (OVs preferentially infect and lyse cancer cells, without causing excessive damage to surrounding healthy tissue, and initiate tumor-specific immunity. The current review describes the use of different oncolytic viruses for cancer therapy and their application to canine and feline cancer.

  19. Tooth fractures in canine clinical practice

    International Nuclear Information System (INIS)

    Tooth fractures constitute a considerable fraction of all tooth diseases. Out of the 5,370 dogs treated during four years, 492 were presented with dental problems and 28.3 % of the latter were treated for tooth fractures. Canines were the most frequently affected teeth (38.8 %), followed by premolars (33.1 %), incisors (25.9 %), and molars (2.2 %), 55.4 % of the patients with canine and incisor fractures being large breed dogs. Fractures of premolars (mostly of 108, 208) were divided evenly irrespective of breed or body size. Nonsurgical endodontic treatment yielded good therapeutic results in most cases, but repeated treatment was necessary in some patients

    1998-10-01

    Objective: The purpose of this study was to evaluate the enhancement characteristics of the normal uterine body and cervix using dynamic contrast-enhanced helical CT. Methods: Thirty-eight women scheduled for pelvic CT for non-gynecologic malignancies underwent dynamic contrast-enhanced helical CT of the pelvis. Data acquisition was during the arterial phase (30-45 s after the start of injection), the parenchymal phase (90-120 s after the start of injection), and delayed phase (3-9 min after the start of injection). The images were evaluated by four radiologists for the pattern of myometrial and cervical enhancement. Correlation was made with the age and menstrual status of the patients. Results: In the uterine body, three types of enhancement were observed. Type 1 enhancement, seen in 16 patients (42%), was characterized by the visualization of a subendometrial zone of enhancement, 30-120 s after the start of injection. Eight of these patients also showed an enhancing zone in the outer myometrium. Both zones were transitory, and in all cases, the uterus became homogeneous in the delayed phase. This pattern was seen predominantly in premenopausal women with a mean age of 34 years. Type 2 enhancement, seen in 17 cases (45%), was defined by the absence of subendometrial enhancement in the early phase. Enhancement was either diffuse from the outset or originated in the outer myometrium. This pattern was seen nearly equally in premenopausal and postmenopausal women with a mean age of 40 years. Type 3 enhancement was seen in five postmenopausal patients (13%) with a mean age of 53 years and was characterized by faint diffuse enhancement. In the cervix, a zonal pattern of enhancement defining inner and outer stroma was seen in 23 patients (61%). Fifteen patients were premenopausal and eight were postmenopausal. Conclusion: In this study, we have shown a transitory zonal distribution of the contrast in the myometrium and cervix using dynamic contrast-enhanced helical CT

  1. Analysis of adverse reactions and complications of transcatheter uterine artery embolization (TUAE) for uterine fibroids

    International Nuclear Information System (INIS)

    Objective: To investigate the adverse reactions and complications as well as their preventive and therapeutic measures of TUAE for uterine fibroids. Methods: One hundred and eighty-two patients with uterine fibroids were treated by TUAE. Bilateral uterine arteries were embolized using lipiodol-pingyangmycin emulsion (LPE), together with Gelfoam particles. All patients were hospitalized for 3 to 10 days after TUAE and were followed up for 1 to 24 months to observe the adverse reactions and complications. Results: Adverse reactions of TUAE included postembolization syndrome ( n 182); urinary irritation ( n = 24), and hyporrhea of vagina ( n = 25 ) . Complications of TUAE included expelling of necrotic fibroids per vagina ( n = 5 ); urinary retention ( n = 10); urinary tract infection ( n = 1 ); ulcer of labia minora ( n = 1 ); ecchymosis and ulceration on buttock ( n = 1), and secondary infection of chocolate cyst of ovary. ( n = 1 ). All the above-mentioned side effects of TUAE recovered to normal after expectant or especial treatment without any sequels left. Conclusion: The adverse reactions of TUAE are reversible and the complications of TUAE are preventable and curable

    To assess the efficacy of superselective intra-arterial chemotherapy(SSIAC) via the bilateral uterine arteries in cases of cervical carcinoma. Eighteen patients with stage 2 {sub a}(n=10), 2 {sub b}(n=7), or 3 {sub a}(n=1) cervical carcinoma underwent one(n=2) or two(n=16) courses of preoperative SSIAC with Vincristine, Cisplatin, and Mitomycin C. We estimated the extent of reduction of tumor volume and improvement of stage, comparing pre-SSIAC MRI to postoperative results. Tumor vascularity, as seen on uterine arteriography, and procedural complications, were also evaluated. A marked reduction in tumor volume was observed in all patients, an average reduction volume of 94.7%. Improvement of stage was noted in 16 patients, and in six of these, no residual viable tumor or microinvasive residual tumor was seen. On angiography, tumor hypervascularity was demonstrated in seven patients, but its degree was not substantially related to therapeutic response. In no case did significant systemic complications of result from chemotherapy; in one patient, however, we experienced a serious complication of necrotizing cystitis due to malpositioning of a catheter in the superior vesical artery. SSIAC via the bilateral uterine arteries is an effective complementary modality for the treatment of various stages of cervical carcinoma.

    2016-09-01

    Uterine fibroids occur in approximately 50% of women over the age of 40 years, and an estimated 50% of those are symptomatic. Menorrhagia is the most common symptom and the primary indication for treatment, although bulk symptoms often occur and can be treated. Pharmacotherapy is typically inadequate unless it can be expected to successfully bridge to menopause or allow for a less-invasive intervention. However, hormonal therapies have risks. Hysterectomy is still the most commonly performed procedure for symptomatic fibroids and has the lowest rate of reintervention (compared with myomectomy or uterine artery embolization [UAE]), but rates of more serious complications are higher and patient satisfaction and ability to return to normal activities may also be less favorable. Myomectomy is not necessarily less morbid than hysterectomy and may have a greater failure rate than UAE. Techniques and devices vary with little standardization, and operator experience is crucial to success. The largest studies of UAE show very low rates of serious complications and rapid recovery. UAE significantly improves symptoms related to uterine fibroids in 85%-90% of patients. Herein, this article will discuss the nature of fibroids and their diagnosis, pharmacotherapy, surgical treatment, and nonsurgical interventional treatment, including UAE and magnetic resonance-guided focused ultrasound.

    Full Text Available Ehrlichia canis is a rickettsial intracellular obligate bacterial pathogen and agent of canine monocytic ehrlichiosis. The prevalence of this disease in veterinary medicine can vary depending on the diagnostic method used and the geographic location. One hundred and fifty-two canine blood samples from six veterinary clinics and two shelters from Sinaloa State (Mexico were analyzed in this study. All animals were suspected of having Canine Monocytic Ehrlichiosis (CME. The diagnostic methods used were the ELISA (Snap4Dx, IDEXX together with blood smear and platelet count. From all dogs blood samples analyzed, 74.3% were positive to E. canis by ELISA and 40.1% were positive by blood smear. The sensitivity and specificity observed in the ELISA test were 78.8% and 86.7%. In addition, thrombocytopenia was presented in 87.6% of positive dogs. The predominant clinical manifestations observed were fever, anorexia, depression, lethargy, and petechiae. Consequently, this is the first report in which the morulae were visualized in the blood samples, and E. canis-specific antibodies were detected in dogs from Sinaloa, Northwest of Mexico.

    International Nuclear Information System (INIS)

    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.

    Pregnancy in a non-communicating rudimentary horn is an extremely rare form of ectopic gestation. The rudimentary horn may or may not communicate with the uterine cavity with the majority of cases being non-communicating. The patient exhibits features of acute abdomen and carries a high risk of maternal death. Even modern scans remain elusive whereas laparatomy remains the confirmatory procedure for the diagnosis. Because of the varied muscular constitution in the thickness and distensibility of the wall of the rudimentary horn, pregnancy is accommodated for a variable period of gestation. Here, we report three cases of pregnancy in a non-communicating rudimentary horn of the uterus in different periods of gestation, their outcome and a review of the available literature.

    Twenty-two samples, taken from eight pathological proved uterine myoma patients, were embedded in paraffin and cut into slices of identical thickness (4.0 μm). After deparaffinization, washing and drying, the slices of myomal tissue and their neighboring myometrial tissue were bombarded by 2.0 MeV proton beams from a 3 MV Van de Graaff accelerator. The induced characteristic X-rays were then detected and analyzed using a HPGe detector system. The absolute concentrations of trace elements contained in tumors and normal tissues of human myomal uterus were determined, in reference to a known concentration of doped yttrium. Significant correlations between the concentration of elements, both in tumors and in normal tissues, were found.

  13. Radiotherapy in benign uterine bleeding disorders

    International Nuclear Information System (INIS)

    Radiotherapy was earlier a method of choice for treatment of benign bleeding disorders (metropathia), especially in woman of high surgical risk. During the period 1912 to 1977 933 women with benign bleeding disorders were treated at Radiumhemmet with intracavitary brachytherapy or external irradiation or a combination of both. The result with regard to cure of the uterine bleedings was good (48%). Hormonal withdrawal symptoms after treatment were noted in 45% of the patients. In the long term follow up an increased risk of cardiovascular death was found in women treated before menopause. Malignant tumours occurred in 107 cases versus 90.2 expected. The estimated ovarian dose of ionizing radiation varied from 3.5 Gy to 6.0 Gy for the three standard techniques. Two women gave birth to a healthy child 4 and 5 years after intracavitary radium treatment. The estimated absorbed dose to the ovaries in these two women were 1 Gy and 4 Gy, respectively

    Full Text Available Uterine fatty tumors are rare variants of benign leiomyoma. Lipoleiomyoma, lipomyoma, fibromyolipoma are various synonyms for this lesion. They usually occur in the obese perimenopausal and postmenopausal females in the age group 50-70 years and 90% cases occur in patients older than 40 years. There were only few cases reported in the literature. These lesions are interesting due to the occasional diagnostic confusion with sarcomas and the curiosity regarding its histogenesis. We are presenting three cases of lipoleiomyoma whose age ranged from 40 to 50 years with clinical, radiologic and pathologic correlation. All three cases came with complaints of abnormal vaginal bleeding and found to have intramural heteroechoic nodule in the ultrasonogram.

    Full Text Available On the basis of our investigations it was possible to conclude that intrauterine treatment of sows with puerperal uterine infections with sterile YCW (Yeast Cell Wall resulted in significant clinical improvement. The percent of recidivism was the lowest (10% in groups of sows treated with 10 and 20 g of YCW. The degree of bacterial CFU (Colony Forming Units reduction in samples of sows uterine flushings following instillation of YCW (5, 10 and 20 g was wery high and ranged from 1361 to 1444 times, while in sows treated with Lotagen 2% solution (100 mL this parametar was only 32. At the moment of weaning, piglets from sows treated with 10 and 20 g of YCW were heavier when compared to the control and Lotagen group and their DBWG (Daily Body Weight Gain was higher when compared to the Lotagen and control group. Treatment of sows by IU instillation of YCW did not influence the number of piglets in the next breeding cycle.

    2016-01-01

    BACKGROUND Uterine papillary serous carcinoma (UPSC) is a highly malignant form of endometrial cancer with a high propensity for metastases and recurrences even when there is minimal or no myometrial invasion. It usually metastasizes to the pelvis, retroperitoneal lymph nodes, upper abdomen, and peritoneum. However, adrenal metastases from UPSC is extremely rare. Here, we present a case of UPSC with adrenal metastasis that occurred 6 years after the initial diagnosis. CASE REPORT A 60-year-old woman previously diagnosed with uterine papillary serous carcinoma at an outside facility presented in September of 2006 with postmenopausal bleeding. She underwent comprehensive surgical staging with FIGO (International Federation of Gynecology and Obstetrics) stage 2. Post-operatively, the patient was treated with radiation and chemotherapy. The treatment was completed in April of 2007. The patient had no evidence of disease until July 2009 when she was found to have a mass highly suspicious for malignancy. Subsequently, she underwent right upper lobectomy. The morphology of the carcinoma was consistent with UPSC. She refused chemotherapy due to a previous history of chemotherapy-induced neuropathy. The patient was followed up with regular computed tomography (CT) scans. In October 2012 a new right adrenal nodule was seen on CT, which showed intense metabolic uptake on positron emission tomography (PET)/CT scan. The patient underwent right adrenalectomy. Pathology of the surgical specimen was consistent with UPSC. CONCLUSIONS UPSC is an aggressive variant of endometrial cancer associated with high recurrence rate and poor prognoses. Long-term follow-up is needed because there is a possibility of late metastases, as in this case. PMID:27117594

    Escherichia coli is the most common bacterial agent isolated from canine pyometra. The frequencies of 24 virulence genes and pulsed field gel electrophoresis (PFGE) profiles were determined for 23 E. coli isolates from cases of canine pyometra in Brazil. The frequencies of virulence genes were 91.3% fimH, 91.3% irp-2, 82.6% fyuA, 56.5% iroN, 47.8% traT, 39.1% usp, 34.8% sfaD/E, 34.8% tsh, 30.4% papC, 30.4% hlyA, 26.1% papGIII, 26.1% cnf-1, 21.7% papE/F, 21.7% iss, 17.4% iutA, 17.4% ompT, 17.4% cvaC, 17.4% hlyF, 17.4% iucD, 13.0% iucC, 13.0% astA, 4.3% papGII, 0% afaB/C and 0% papGI. The high frequency of yersiniabactin (fyuA and irp2) and salmochelin (iroN) genes suggests that iron uptake systems might be important in the pathogenesis of canine pyometra. PFGE profiles of 19 isolates were heterogeneous, confirming that E. coli isolates from canine pyometra are unlikely to be epidemic clones. PMID:25201253

    Monoclonal antibodies are leading agents for therapeutic treatment of human diseases, but are limited in use by the paucity of clinically relevant models for validation. Sporadic canine tumours mimic the features of some human equivalents. Developing canine immunotherapeutics can be an approach for modeling human disease responses. Rituximab is a pioneering agent used to treat human hematological malignancies. Biologic mimics that target canine CD20 are just being developed by the biotechnology industry. Towards a comparative canine-human model system, we have developed a novel anti-CD20 monoclonal antibody (NCD1.2) that binds both human and canine CD20. NCD1.2 has a sub-nanomolar Kd as defined by an octet red binding assay. Using FACS, NCD1.2 binds to clinically derived canine cells including B-cells in peripheral blood and in different histotypes of B-cell lymphoma. Immunohistochemical staining of canine tissues indicates that the NCD1.2 binds to membrane localized cells in Diffuse Large B-cell lymphoma, Marginal Zone Lymphoma, and other canine B-cell lymphomas. We cloned the heavy and light chains of NCD1.2 from hybridomas to determine whether active scaffolds can be acquired as future biologics tools. The VH and VL genes from the hybridomas were cloned using degenerate primers and packaged as single chains (scFv) into a phage-display library. Surprisingly, we identified two scFv (scFv-3 and scFv-7) isolated from the hybridoma with bioactivity towards CD20. The two scFv had identical VH genes but different VL genes and identical CDR3s, indicating that at least two light chain mRNAs are encoded by NCD1.2 hybridoma cells. Both scFv-3 and scFv-7 were cloned into mammalian vectors for secretion in CHO cells and the antibodies were bioactive towards recombinant CD20 protein or peptide. The scFv-3 and scFv-7 were cloned into an ADEPT-CPG2 bioconjugate vector where bioactivity was retained when expressed in bacterial systems. These data identify a recombinant anti-CD20

    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. PMID:21632170

    A panel of anti-canine leukocyte monoclonal antibodies (MAbs) was produced by immunizing BALB/c mice with canine peripheral blood mononuclear cells (PBMC), either resting or stimulated with concanavalin A (ConA). Three out of 28 clones-IH1, AB6, and HG6-screened by ELISA and producing antibody with the highest specificity for canine cell immunostaining, were subjected to three subsequent subcloning steps by limiting dilution, and selected for further characterization. These MAbs belonged to IgG1 (HG6 and IH1) and IgG2a (AB6) isotypes. The distribution of cell populations expressing the antigen recognized by the antibodies was identified by indirect immunoflorescence on canine PBMC and on tissue sections of lymph node, spleen, liver and skin. The possible crossreactivity with human PBMC was also examined in immunocytochemistry. One of the antibodies specifically recognized macrophages. The MAbs presented here can be foreseen as possible valuable diagnostic and research tools to study immune functions in dogs. PMID:15165486

  17. Experimental Forelimb Allotransplantation in Canine Model

    2016-01-01

    As reconstructive transplantation is gaining popularity as a viable alternative for upper limb amputees, it is becoming increasingly important for plastic surgeons to renew surgical skills and knowledge of this area. Forelimb allotransplantation research has been performed previously in rodent and swine models. However, preclinical canine forelimb allotransplantation studies are lacking in the literature. The purpose of this paper is to provide an overview of the surgical skills necessary to successfully perform forelimb transplantation in canines as a means to prepare for clinical application. A total of 18 transplantation operations on canines were performed. The recipient limb was shortened at the one-third proximal forearm level. The operation was performed in the following order: bones (two reconstructive plates), muscles and tendons (separately sutured), nerves (median, ulnar, and radial nerve), arteries (two), and veins (two). The total mean time of transplantation was 5 hours ± 30 minutes. All of the animals that received transplantation were treated with FK-506 (tacrolimus, 2 mg/kg) for 7 days after surgery. Most allografts survived with perfect viability without vascular problems during the early postoperative period. The canine forelimb allotransplantation model is well qualified to be a suitable training model for standard transplantation and future research work. PMID:27597952

    Objective: To evaluate the diagnostic implications of immunohistochemical markers in uterine smooth muscle tumors. Methods: Formalin-fixed paraffin-embedded tissue blocks were selected from 17 uterine leiomyosarcomas, 40 uterine unusual leiomyomas and 25 uterine usual leiomyomas. Utilizing immunohistochemical techniques with antigen retrieval, serial sections of each tumor for immunoreactivity with myogenic markers, ovarian steroid receptors, CD44v3, proliferating cell nuclear antigen and mast cells were assessed. Results: Although the myogenic markers and CD44v3 showed less frequent positivity in uterine leiomyosarcomas than those in unusual leiomyomas, they were not reliable markers for differentiating leiomyosarcoma from leiomyoma. Uterine leiomyosarcoma tended to have lower ovarian steroid receptors immunoreactivity rates than leiomyoma. Leiomyoma tended to have a higher quantity of intratumoral mast cells than leiomyosarcoma, while the expression of proliferating cell nuclear antigen was lower in them. Conclusion: Because the estimation of mitotic count was subject to significant variation, the immunohistochemical expression of ovarian steroid receptors, mast cells and proliferating cell nuclear antigen seemed to be helpful for the discrimination of unusual leiomyoma from leiomyosarcoma.

    Absolute uterine factor infertility (UFI) refers to the refractory causes of female infertility stemming from the anatomical or physiological inability of a uterus to sustain gestation. Today, uterine factor infertility affects 3-5% of the population. Traditionally, although surrogacy and adoption have been the only viable options for females affected by this condition, the uterine transplant is currently under investigation as a potential medical alternative for women who desire to go through the experience of pregnancy. Although animal models have shown promising results, human transplantation cases have only been described in case reports and a successful transplant leading to gestation is yet to occur in humans. Notwithstanding the intricate medical and scientific complexities that a uterine transplant places on the medical minds of our time, ethical questions on this matter pose a similar, if not greater, challenge. In light of these facts, this article attempts to present the ethical issues in the context of experimentation and standard practice which surround this controversial and potentially paradigm-altering procedure; and given these, introduces "The Montreal Criteria for the Ethical Feasibility of Uterine Transplantation", a set of proposed criteria required for a woman to be ethically considered a candidate for uterine transplantation.

    Mucin (MUC) 1 is an inducible innate immune effector, an important component of defense against bacterial invasion, and is linked with infertility in humans. The objectives were to evaluate messenger RNA (mRNA) expression of MUC1 and cytokine genes in the endometrium of cows with various postpartum uterine inflammatory conditions or with a history of repeat breeding. Endometrial samples were collected from lactating dairy cows diagnosed with metritis (n = 4), endometritis (n = 4), subclinical endometritis (n = 4), or no uterine pathology (normal; n = 4). In addition, endometrial samples were collected from repeat breeder cows with (n = 4) or without (n = 4) subclinical endometritis, and unaffected cows (n = 4). Quantitative polymerase chain reaction was used to determine mRNA abundances of MUC1, Toll-like receptor (TLR) 4, interleukin (IL) 1β, IL6, IL8, tumor necrosis factor (TNF) α, insulin-like growth factor (IGF) 1, and IGF-binding protein (BP) 2. The mRNA expressions were significantly greater for cows with metritis and clinical endometritis compared with cows with no uterine inflammation, except for IL6. However, mRNA expressions for these target genes were not different for cows with subclinical endometritis, compared with cows without uterine inflammation, except for IL1β and TNFα mRNA (P cows with subclinical endometritis compared with normal cows. However, in repeat breeder cows without subclinical endometritis, only expressions of MUC1, IGF1, and IGF BP2 were greater compared with normal cows (P cows. Perhaps, these altered gene expressions contribute to endometrial insufficiency and consequently pregnancy wastage. PMID:24576715

    Bacterial vaginosis (BV) is the main cause of vaginal dysbacteriosis in the women during the reproductive age. It is an entity in which many studies have focused for years and which is still open for discussion topics. This is due to the diversity of microorganisms that cause it and therefore, its difficult treatment. Bacterial vaginosis is probably the result of vaginal colonization by complex bacterial communities, many of them non-cultivable and with interdependent metabolism where anaerobic populations most likely play an important role in its pathogenesis. The main symptoms are an increase of vaginal discharge and the unpleasant smell of it. It can lead to serious consequences for women, such as an increased risk of contracting sexually transmitted infections including human immunodeficiency virus and upper genital tract and pregnancy complications. Gram stain is the gold standard for microbiological diagnosis of BV, but can also be diagnosed using the Amsel clinical criteria. It should not be considered a sexually transmitted disease but it is highly related to sex. Recurrence is the main problem of medical treatment. Apart from BV, there are other dysbacteriosis less characterized like aerobic vaginitis of which further studies are coming slowly but are achieving more attention and consensus among specialists.

    The Sicilian province of Catania is an active foci for human visceral leishmaniasis (VL) in the Mediterranean area. Approximately 10 to 15 cases of VL are diagnosed via hospital admissions each year in this community. Recently, an increase in VL case reporting by Sicilian physicians was noted, with 38 and 37 VL cases in 1996 and 1997, respectively. Before 1995, there were no reported VL cases among U.S. military personnel or their family members living in Sicily. However, since 1996, there have been four cases referred to Walter Reed Army Medical Center for diagnosis and treatment, all involving the children of personnel assigned to Naval Air Station Sigonella. Exposure histories for all infected individuals excluded exposure to Leishmania parasites outside of Sicily. All patients lived in areas where vectoring sandflies are present. All had dogs as family pets. To evaluate the level of infection among dogs owned by Navy personnel and their families, U.S. Navy Environmental and Preventive Medicine Unit 7, in a collaborative study with the U.S. Army Veterinary Clinic, Naval Air Station Sigonella, and the Walter Reed Army Institute of Research, performed clinical evaluation and serological testing of 50 dogs residing with U.S. personnel assigned to Naval Air Station Sigonella. The data indicate a high exposure rate to Leishmania (60% of the animals tested had elevated immunoglobulin M antibody levels) in the study population, suggesting that they were infected with Leishmania infantum. Distribution of seropositive dogs by sex was equal. Most of the dogs studied appeared to be in good health. However, inapparent infection of dogs, seen by Italian veterinarians, has been observed throughout all areas of Catania. Sandflies responsible for vectoring L. infantum were trapped in the same locations as the dogs sampled in this study. The level of subclinical infection was 75% among seropositive dogs. The overall level of canine infection observed was higher than expected

    Currently, no early pregnancy marker has been identified in the bitch. However, significantly decreased concentrations of heat-shock protein (HSP) 70 and increased activity of matrix metalloproteinases (MMP) 2,9 were detected in serum from bitches during the pre-implantation period between days 5 and 13 after mating, that is, 2-3 days after ovulation as determined by the measurement of progesterone and vaginal cytology. Especially during the implantation period and thereafter (days 15-55), high serum concentrations of antibodies against desmin are present, which is believed to indicate or regulate decidualization. Pre-implantation embryos express mRNA for enzymes and cytokines, known to promote and regulate trophoblast growth, and some intrauterine changings like the increased activity of MMP 2,9 in maternal endometrium are dependant on the presence of embryos. Some mechanisms that protect canine embryos from attack by the maternal immune system can also be identified. The embryos express CD4, a receptor known to interact with immune cells. They, furthermore, do not express MHC I and II, which might prevent them from being recognized as foreign antigen. Pre-implantation embryos express FasL, which probably renders them able to destroy Fas-bearing cytotoxic T cells. Furthermore, the uterus during pre-implantation and implantation expresses cytokines that modulate the intrauterine milieu towards a predominance of Th2 cells. During pre-implantation and implantation, an increased uterine expression of platelet activating factor (PAF) and PAFR, vascular endothelial growth factor (VEGF) and EGFR2 as well as epithelial growth factor (EGF) is characteristic. Towards placentation, the upregulation of leukaemia inhibiting factor (LIF) and at placentation the expression of insulin-like growth factor(IGF)2 and granulocyte-macrophage colony-stimulating factor (GM-CSF) are striking. Progesterone receptor (PR) appears to be downregulated inside the uterus except at placentation

    Canine oocytes are ovulated at prophase of the first meiotic division and undergo maturation in the distal part of the oviduct for at least 48-72 h. Because of these differences from other domestic mammals, the efficiency of in vitro maturation (IVM) of canine oocyte is very low. The present study was conducted to evaluate the effects of canine serum on IVM of canine oocytes recovered from ovaries in various reproductive states (follicular, luteal or anestrous stages). Oocytes were recovered by mincing ovaries from bitches presented for ovariohysterectomy at various stages of the estrous cycle. Heat-inactivated canine serum was prepared with blood taken from dogs at the anestrous, estrous or diestrous stage of the estrous cycle as determined by progesterone concentration and vaginal cytology. Oocytes were cultured for 72 h in tissue culture medium (TCM)-199 supplemented with 10% canine anestrous, estrous or diestrous serum or fetal bovine serum (FBS) (experiment 1), or supplemented with 0 (control), 5%, 10% or 20% canine estrous serum (experiment 2). In experiment 1, IVM of oocytes collected at the follicular stage of the estrous cycle to metaphase II (MII) stage was higher (p < 0.05) with canine estrous serum (14.2%) than with canine anestrous (5.2%) or diestrous serum (6.3%), FBS (2.2%) or in the control (2.2%). In experiment 2, oocytes collected at the follicular stage of the estrous cycle cultured in TCM-199 with 10% canine estrous serum showed a higher maturation rate to MII stage (13.5%, p < 0.05) compared with those cultured with 5% (1.3% MII) or 20% canine estrous serum (5.1% MII) or the control (2.7% MII). In conclusion, our results demonstrate that supplementing culture medium with 10% canine estrous serum improves IVM of canine follicular stage oocytes. PMID:16261767

    Recent molecular studies have revealed a complex microbiota in the dog intestine. Convincing evidence has been reported linking changes in microbial communities to acute and chronic gastrointestinal inflammation, especially in canine inflammatory bowel disease (IBD). The most common microbial changes observed in intestinal inflammation are decreases in the bacterial phyla Firmicutes (i.e., Lachnospiraceae, Ruminococcaceae, and ) and Bacteroidetes, with concurrent increases in Proteobacteria (i.e., ). Due to the important role of microbial-derived metabolites for host health, it is important to elucidate the metabolic consequences of gastrointestinal dysbiosis and physiological pathways implicated in specific disease phenotypes. Metagenomic studies have used shotgun sequencing of DNA as well as phylogenetic investigation of communities by reconstruction of unobserved states (PICRUSt) to characterize functional changes in the bacterial metagenome in gastrointestinal disease. Furthermore, wide-scale and untargeted measurements of metabolic products derived by the host and the microbiota in intestinal samples allow a better understanding of the functional alterations that occur in gastrointestinal disease. For example, changes in bile acid metabolism and tryptophan catabolism recently have been reported in humans and dogs. Also, metabolites associated with the pentose phosphate pathway were significantly altered in chronic gastrointestinal inflammation and indicate the presence of oxidative stress in dogs with IBD. This review focuses on the advancements made in canine metagenomics and metabolomics and their implications in understanding gastrointestinal disease as well as the development of better treatment approaches.

  11. Uterine Artery Embolization Versus Laparoscopic Uterine Artery Occlusion: The Outcomes of a Prospective, Nonrandomized Clinical Trial

    International Nuclear Information System (INIS)

    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).

  12. Uterine contractions evaluated on cine MR imaging in patients with uterine leiomyomas

    International Nuclear Information System (INIS)

    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

    PCR amplification and sequencing of phylogenetic markers, primarily Small Sub-Unit ribosomal RNA (SSU rRNA) genes, has been the paradigm for defining the taxonomic composition of microbiomes. However, 'universal' SSU rRNA gene PCR primer sets are likely to miss much of the diversity therein. We sequenced a library comprising purified and reverse-transcribed SSU rRNA (RT-SSU rRNA) molecules from the canine oral microbiome and compared it to a general bacterial 16S rRNA gene PCR amplicon library generated from the same biological sample. In addition, we have developed BIONmeta, a novel, open-source, computer package for the processing and taxonomic classification of the randomly fragmented RT-SSU rRNA reads produced. Direct RT-SSU rRNA sequencing revealed that 16S rRNA molecules belonging to the bacterial phyla Actinobacteria, Bacteroidetes, Firmicutes, Proteobacteria and Spirochaetes, were most abundant in the canine oral microbiome (92.5% of total bacterial SSU rRNA). The direct rRNA sequencing approach detected greater taxonomic diversity (1 additional phylum, 2 classes, 1 order, 10 families and 61 genera) when compared with general bacterial 16S rRNA amplicons from the same sample, simultaneously provided SSU rRNA gene inventories of Bacteria, Archaea and Eukarya, and detected significant numbers of sequences not recognised by 'universal' primer sets. Proteobacteria and Spirochaetes were found to be under-represented by PCR-based analysis of the microbiome, and this was due to primer mismatches and taxon-specific variations in amplification efficiency, validated by qPCR analysis of 16S rRNA amplicons from a mock community. This demonstrated the veracity of direct RT-SSU rRNA sequencing for molecular microbial ecology. PMID:27276347

    The presence of an impacted mandibular canine is one of the most difficult challenges that an orthodontist will meet. Orthodontic treatment is planned on an individual basis after thoroughly considering the patient's overall facial and dentoskeletal characteristics; the duration, risks, and costs of treatment; patient preferences; and the orthodontist's experience. This article reports an orthodontic treatment of a boy, age 12.9 years, with an impacted mandibular canine in the permanent dentition that was successfully managed. Radiographic analysis indicated a transmigration of the mandibular right canine. The orthodontic treatment plan included extraction of the deciduous right canine followed by surgical exposure and ligation of the permanent canine. Eruption was properly guided, and the correct position of the tooth was achieved. This challenging treatment approach is described in detail, including the mechanics used to align the impacted canine. PMID:26502299

    Background 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.Methods 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.Results 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 <0.001). The rate of malpresentation was significantly higher in patients with septated uterus in comparison with patients with uterus unicorns (P <0.05).Conclusions 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.

  2. Human uterine wall tension trajectories and the onset of parturition.

    Directory of Open Access Journals (Sweden)

    Peter Sokolowski

    Full Text Available Uterine wall tension is thought to be an important determinant of the onset of labor in pregnant women. We characterize human uterine wall tension using ultrasound from the second trimester of pregnancy until parturition and compare preterm, term and twin pregnancies. A total of 320 pregnant women were followed from first antenatal visit to delivery during the period 2000-2004 at the John Hunter Hospital, NSW, Australia. The uterine wall thickness, length, anterior-posterior diameter and transverse diameter were determined by serial ultrasounds. Subjects were divided into three groups: women with singleton pregnancies and spontaneous labor onset, either preterm or term and women with twin pregnancies. Intrauterine pressure results from the literature were combined with our data to form trajectories for uterine wall thickness, volume and tension for each woman using the prolate ellipsoid method and the groups were compared at 20, 25 and 30 weeks gestation. Uterine wall tension followed an exponential curve, with results increasing throughout pregnancy with the site of maximum tension on the anterior wall. For those delivering preterm, uterine wall thickness was increased P < 0.05 compared with term. For twin pregnancies intrauterine volume was increased compared to singletons (P < 0.001, but wall thickness was not. There was no evidence for increased tension in those delivering preterm or those with twin gestations. These data are not consistent with a role for high uterine wall tension as a causal factor in preterm spontaneous labor in singleton or twin gestations. It seems likely that hormonal differences in multiple gestations are responsible for increased rates of preterm birth in this group rather than increased tension.

    The mucosal lining (endometrium) of the human uterus undergoes cyclical processes of regeneration, differentiation and shedding as part of the menstrual cycle. Endometrial regeneration also follows parturition, almost complete resection and in post-menopausal women taking estrogen replacement therapy. In non-menstruating species, there are cycles of endometrial growth and apoptosis rather than physical shedding. The concept that endometrial stem/progenitor cells are responsible for the remarkable regenerative capacity of endometrium was proposed many years ago. However, attempts to isolate, characterize and locate endometrial stem cells have only been undertaken in the last few years as experimental approaches to identify adult stem/progenitor cells in other tissues have been developed. Adult stem cells are defined by their functional properties rather than by marker expression. Evidence for the existence of adult stem/progenitor cells in human and mouse endometrium is now emerging because functional stem cell assays are being applied to uterine cells and tissues. These fundamental studies on endometrial stem/progenitor cells will provide new insights into the pathophysiology of various gynaecological disorders associated with abnormal endometrial proliferation, including endometrial cancer, endometrial hyperplasia, endometriosis and adenomyosis.

    Full Text Available Fibroids are the most common benign tumors of the genital organs of women in reproductive age. Achieving reproductive function later in life, with more frequent use of assisted reproductive technologies, leads to an increased number of pregnancies complicated with fibroids. Their size may change during pregnancy, but the changes are mostly individual. Most fibroids stop growing or decline during the puerperium. The effect of fibroids on pregnancy depends on their number, size and location. The mechanisms bringing about perinatal complications are not fully understood. Fibroids during pregnancy can cause many perinatal complications, such as bleeding in pregnancy, miscarriage, pain due to red degeneration, malpresentation, preterm labor, premature rupture of membranes, placental abruption and obstruction of delivery and are associated with higher incidence of cesarean section, operative vaginal delivery, uterine atony and postpartum hemorrhage. Postpartum hysterectomy in these women is also more likely than in general population. Postpartum infections are more common in patients with fibroids, and myomas may also cause retained placenta. The most common cause of neonatal morbidity is prematurity, due to pregnancy ending in an earlier gestational age. Monitoring of pregnancies complicated with fibroids is essentially indistinguishable from monitoring normal pregnancies. Therapy includes only bed rest and observation, symptomatic therapy in case of pain and intensive fetal surveillance, and surgery in the acute situations.

    Cervical Cancer is the second most common cancer among women worldwide and the leading cause of cancer mortality of women in developing countries. If detected early and treated adequately, cervical cancer can be virtually prevented. Cervical precursor lesions and invasive cancer exhibit certain morphologic features that can be identified during a visual inspection exam. Digital imaging technologies allow us to assist the physician with a Computer-Aided Diagnosis (CAD) system. In colposcopy, epithelium that turns white after application of acetic acid is called acetowhite epithelium. Acetowhite epithelium is one of the major diagnostic features observed in detecting cancer and pre-cancerous regions. Automatic extraction of acetowhite regions from cervical images has been a challenging task due to specular reflection, various illumination conditions, and most importantly, large intra-patient variation. This paper presents a multi-step acetowhite region detection system to analyze the acetowhite lesions in cervical images automatically. First, the system calibrates the color of the cervical images to be independent of screening devices. Second, the anatomy of the uterine cervix is analyzed in terms of cervix region, external os region, columnar region, and squamous region. Third, the squamous region is further analyzed and subregions based on three levels of acetowhite are identified. The extracted acetowhite regions are accompanied by color scores to indicate the different levels of acetowhite. The system has been evaluated by 40 human subjects' data and demonstrates high correlation with experts' annotations.

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

    International Nuclear Information System (INIS)

    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.

    2008-01-01

    Full Text Available Abstract Background Uterine serpins are members of the serine proteinase inhibitor superfamily. Like some other serpins, these proteins do not appear to be functional proteinase inhibitors. The most studied member of the group, ovine uterine serpin (OvUS, inhibits proliferation of several cell types including activated lymphocytes, bovine preimplantation embryos, and cell lines for lymphoma, canine primary osteosarcoma and human prostate cancer (PC-3 cells. The goal for the present study was to evaluate the mechanism by which OvUS inhibits cell proliferation. In particular, it was tested whether inhibition of DNA synthesis in PC-3 cells involves cytotoxic actions of OvUS or the induction of apoptosis. The effect of OvUS in the production of the autocrine and angiogenic cytokine interleukin (IL-8 by PC-3 cells was also determined. Finally, it was tested whether OvUS blocks specific steps in the cell cycle using both PC-3 cells and lymphocytes. Results Recombinant OvUS blocked proliferation of PC-3 cells at concentrations as low as 8 μg/ml as determined by measurements of [3H]thymidine incorporation or ATP content per well. Treatment of PC-3 cells with OvUS did not cause cytotoxicity or apoptosis or alter interleukin-8 secretion into medium. Results from flow cytometry experiments showed that OvUS blocked the entry of PC-3 cells into S phase and the exit from G2/M phase. In addition, OvUS blocked entry of lymphocytes into S phase following activation of proliferation with phytohemagglutinin. Conclusion Results indicate that OvUS acts to block cell proliferation through disruption of the cell cycle dynamics rather than induction of cytotoxicity or apoptosis. The finding that OvUS can regulate cell proliferation makes this one of only a few serpins that function to inhibit cell growth.

    International Nuclear Information System (INIS)

    Polish strains of canine parvovirus isolated between 1982 and 1993 were examined to determine the extent to which the virus has evolved antigenically and genetically over eleven years. Two CPV isolates obtained in Warsaw in 1982 and Pulawy in 1993, were examined using monoclonal antibody typing, restriction analysis and sequencing VP-2 protein gene. Five other isolates from Warsaw and Pulawy were tested with the panel of monoclonal antibodies specific to CPV-2, CPV-2a and common for canine parvovirus, feline panleukopenia virus and milk enteritis virus. Results of the studies demonstrated that all isolates tested represented CPV-2a antigenic type. Rapid antigenic strain replacement recorded by Parrish and Senda in the U.S.A and Japan was not confirmed in Poland. (author). 30 refs, 2 tabs

    Mammary tumours are the most common neoplasms of female dogs. Compared to mammary tumours of humans and cats, myoepithelial (ME) cell involvement is common in canine mammary tumours (CMT) of any subtype. Since ME cell involvement in CMT influences both histogenetic tumour classification and prognosis, correct identification of ME cells is important. This review describes immunohistochemical methods for identification of canine mammary ME cells used in vivo. In addition, phenotypic and genotypic methods to isolate ME cells for in vitro studies to analyse tumour-suppressor protein production and gene expression are discussed. The contribution of ME cells to both histogenetic classifications and the prognosis of CMT is compared with other species and the potential use of ME cells as a method to identify carcinoma in situ is discussed.

    Characterization of canine coronavirus (CCoV) strains currently in circulation is essential for understanding viral evolution. The aim of this study was to determine the presence of pantropic CCoV type IIa in tissue samples from five puppies that died in Southern Brazil as a result of severe gastroenteritis. Reverse-transcriptase PCR was used to generate amplicons for sequence analysis. Phylogenetic analysis of the CCoV-IIa strains indicated that they were similar to those found in other countries, suggesting a common ancestor of these Brazilian isolates. This is the first report of pantropic CCoV-II in puppies from Latin America and our findings highlight that CCoV should be included as a differential diagnosis when dogs present with clinical signs and lesions typically seen with canine parvovirus infection.

    Full Text Available Objective. To determine the influence of age and parity on the surgical management of uterine fibroids, clinical presentation, presence of pelvic adhesions, cadre of surgeons, and postoperative complications at the Aminu Kano Teaching Hospital, Kano, Nigeria. Methods. A retrospective analysis of 105 cases of uterine fibroids that were managed between 1st January 2003 and 31st December 2007. Results. The period prevalence of uterine fibroids was 24.7% of all major gynecological operations. The mean age was 35.8 ± 7.6 and mean parity 4.7 ± 2.8. Abdominal hysterectomy accounted for 58.1% of the cases and myomectomy 41.9%. The odd of using abdominal hysterectomy was about twice that of myomectomy. Pelvic adhesions were found in 67.6% of the cases. Menorrhagia (86.7% was the commonest symptom, while post operative anemia and pyrexia showed significant association with myomectomy. There was no maternal mortality. Conclusion. Surgical operations for uterine fibroids are safe and common kind of gynecological operations at the Aminu Kano Teaching Hospital. Uterine fibroid is associated more with high parity and dominance of abdominal hysterectomy over myomectomy, because early girl marriage is common in our community.

    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.)

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

    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.

    Full Text Available BACKGROUND: Uterine leiomyomas (fibroids are the most common gynaecological benign tumors in premenopausal women. Evidences support the role of oxidative stress in the development of uterine leiomyoma. We have analysed oxidative stress markers (thiols, advanced oxidized protein products (AOPP, protein carbonyls and nitrates/nitrites in preoperative sera from women with histologically proven uterine leiomyoma. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a laboratory study in a tertiary-care university hospital. Fifty-nine women with histologically proven uterine leiomyoma and ninety-two leiomyoma-free control women have been enrolled in this study. Complete surgical exploration of the abdominopelvic cavity was performed in each patient. Preoperative serum samples were obtained from all study participants to assay serum thiols, AOPP, protein carbonyls and nitrates/nitrites. Concentrations of serum protein carbonyl groups and AOPP were higher in leiomyoma patients than in the control group (p=0.005 and p<0.001, respectively. By contrast, serum thiol levels were lower in leiomyoma patients (p<0.001. We found positive correlations between serum AOPP concentrations and total fibroids weight (r=0.339; p=0.028, serum AOPP and serum protein carbonyls with duration of infertility (r=0.762; p=0.006 and r=0.683; p=0.021, respectively. CONCLUSIONS/SIGNIFICANCE: This study, for the first time, reveals a significant increase of protein oxidative stress status and reduced antioxidant capacity in sera from women with uterine leiomyoma.

    Full Text Available Background: Small intrauterine lesions such as septum, adhesion, polyp, and submucous myoma may be of greater significance in causing implantation failure, poor reproductive performance and abnormal uterine bleeding. We studied effectiveness of therapeutic intervention through operative hysteroscopy in improvement of pregnancy outcome and cessation of abnormal uterine bleeding (AUB in women with pregnancy and fertility problems. Materials and Methods: This prospective cohort study was performed between 2003- 2009 on 65 patients with primary or secondary infertility, recurrent abortion and structural uterine lesions reported in sonography or hysterosalpingography. After hysteroscopic metroplasty, myomectomy, adhesiolysis and polypectomy under laparoscopic guide, we evaluated reproductive outcome, early and late complications, one year after surgery. Results: Among all patients with recurrent abortion, 6 patients (75% complete their pregnancy successfully. Our results showed that pregnancy rate after metroplasty was 58%. Reproductive outcome was poor after myomectomy and adhesiolysis. Abnormal uterine bleeding was improved in 62% of patients. Conclusion: Structural uterine lesions has been assumed to cause infertility, while several studies have shown very poor reproductive performance with high miscarriage and low term delivery rates when malformation is not treated. We show improvement in conceptional outcome and in patient’s chief complaints after hysteroscopy surgery of these anomalies.

    There is little published information on the ultrasonographic appearance of canine renal lymphoma. The purpose of this retrospective study was to provide additional information regarding the ultrasonographic characteristics of canine renal lymphoma, suggest ultrasonographic description criteria, and evaluate the role of fine-needle aspirate cytology in the diagnosis of this disease. The ultrasonographic features of confirmed renal lymphoma were reviewed in ten dogs. Pyelectasia was found in all dogs. Other ultrasonographic findings were loss of corticomedullary distinction (9/10 dogs), renomegaly (8/10 dogs), renal deformity (6/10 dogs), hypoechoic lesion(s) (6/10 dogs), and hyperechoic lesion(s) (2/10 dogs). Hypoechoic lesions were described as masses, nodules, and indistinct areas. In 30% of the cases (3/10 dogs) ultrasound revealed only minor abnormalities, including grade 1 pyelectasia, mild renomegaly, and focal loss of corticomedullary definition. Bilateral lesions were seen in nine dogs (90%). Renal fine-needle aspirates were performed in 9/10 dogs, yielding a diagnosis in seven on first attempt (78%). Two dogs had been given a provisional cytological diagnosis of round cell neoplasia; in one dog lymphoma was confirmed by second aspirate and by tissue core biopsy in the other. In 1/10 dogs, lymphoma was found at necropsy. Findings indicated that ultrasonographic signs of canine renal lymphoma may be subtle, canine renal lymphoma should be included in the differential diagnosis when the above ultrasonographic features are observed, and fine-needle aspirate cytology is a useful method for diagnosing this disease.

    2016-01-01

    Canine Cognitive Dysfunction Syndrome (CCD) is a neurodegenerative disease affecting aging dogs. CCD is an underdiagnosed disease that involves at least 14% of geriatric dogs, but apparently less than 2% of diseased dogs are diagnosed. There are several physiopathological similarities between Alzheimer disease (AD) and CCD, developing amyloid-β deposits in brain parenchyma and blood vessels, brain atrophy and neuronal loss. The clinical signs lead to behavioural changes. They are ...

    Pregnancy in a rudimentary uterine horn is a rare event which can be revealed by uterine rupture. Following the fetal extraction, some authors recommend the ablation of the rudimentary horn, in order to limit the risk of uterine rupture in case of subsequent pregnancy in the same horn. We report the obstetrical outcome of a patient with a history of rudimentary uterine horn rupture the treatment of which was conservative. PMID:18308608

    Full Text Available Infection-related preterm birth is a leading cause of infant mortality and morbidity; knowledge of bacterial populations invading the amniotic cavity and the routes of invasion is required to make progress in the prevention of preterm birth. Significant advances have been made in understanding bacterial communities in the vagina, but much less studied are intra-uterine bacterial populations during pregnancy. A systematic review of data published on the intra-uterine microbiome was performed; molecular information and summaries of species found in healthy individuals and in women with diagnosed infections served to construct a database and to analyse results to date. Thirteen studies fulfilled the review's inclusion criteria. The data of various investigations were collated, organised and re-analysed to achieve a more comprehensive understanding of microbial populations in the intra-amniotic space. The most common intra-amniotic bacterial taxa were species that can colonise the vagina in health and disease; there were others associated with the habitats of the mouth, gastrointestinal tract and respiratory tract. The results suggest a central role for the ascending route of infections during pregnancy, and points to a possible secondary contribution via haematogenous invasion of the intra-amniotic space. The census of the intra-uterine microbiome awaits completion.

    Dogs with spontaneous diseases can exhibit a striking similarity in etiology, clinical manifestation, and disease course when compared to human patients. Therefore, dogs are intensely discussed as a translational model of human disease. In particular, genetic studies in selected dog breeds serve as an excellent tool to identify epilepsy disease genes. In addition, canine epilepsy is discussed as a translational platform for drug testing. On one hand, epileptic dogs might serve as an interesting model by allowing the evaluation of drug efficacy and potency under clinical conditions with a focus on chronic seizures resistant to standard medication, preventive strategies, or status epilepticus. On the other hand, several limitations need to be considered including owner-based seizure monitoring, species differences in pharmacokinetics and drug interactions, as well as cost-intensiveness. The review gives an overview on the current state of knowledge regarding the etiology, clinical manifestation, pathology, and drug response of canine epilepsy, also pointing out the urgent need for further research on specific aspects. Moreover, the putative advantages, the disadvantages, and limitations of antiepileptic drug testing in canine epilepsy are critically discussed. PMID:23506100

    Canine kobuviruses (CaKVs) are newly recognized picornaviruses recently detected in dogs in the US. By molecular analysis of the whole genome, CaKV that appeared genetically closest to the murine kobuvirus (MuKV) and to the human Aichi virus (AiV), may be classified in the Kobuvirus genus as new genotype (CaKV type 1) within the species Aichivirus A. To date, there are no information on the epidemiology of these novel viruses in other continents. In this study, by screening a collection of 256 dog fecal samples either from diarrhoeic or asymptomatic animals, CaKV was identified in six specimens with an overall prevalence of 2.34% (6/256). All the positive dogs presented diarrhea and were found to be infected by CaKV alone or in mixed infections with canine coronavirus (CCoV) and/or canine parvovirus type 2 (CPV-2). By molecular analysis of the partial 3D gene, all the strains detected displayed a close relatedness with the CaKVs recently identified in the US. This study provides evidence that CaKVs circulate in diarrhoeic dogs in Italy and are not geographically restricted to the North American continent, where they were first signaled. PMID:23806200

    2014-07-01

    A marked increase in canine leptospirosis was observed in Switzerland over 10 years with a peak incidence of 28.1 diagnosed cases/100,000 dogs/year in the most affected canton. With 95% affected dogs living at altitudes 90% cases being diagnosed between May and October. The increasing yearly incidence however was only weakly correlated with climatic data including number of summer (r2 0.25) or rainy days (r2 0.38). Serovars Australis and Bratislava showed the highest seropositivity rates with 70.5% and 69.1%, respectively. Main clinical manifestations included renal (99.6%), pulmonary (76.7%), hepatic (26.0%), and hemorrhagic syndromes (18.2%), leading to a high mortality rate (43.3%). Similar to the human disease, liver involvement had the strongest association with negative outcome (OR 16.3). Based on these data, canine leptospirosis presents similar features and severity as the human infection for which it therefore can be considered a model. Its re-emergence in a temperate country with very high incidence rates in canines should thus be viewed as a warning and emphasize the need for increased awareness in other species. PMID:25032740

    Malignant lymphomas are one of the most common malignant tumours occurring in dogs. The basic method of lymphoma diagnosis in human, as well as in canine oncology is histopathology supported by immunohistochemistry. It was suggested that in veterinary medicine excisional biopsy of lymph node and histopathology should be considered only where the cytologic diagnosis is equivocal or needs to be confirmed. There are at least three basic reasons for which cytological examination ought to be accepted as a sufficient and reliable diagnostic method for lymphoma in dogs. Firstly, most dog owners consider the fine-needle biopsy as an acceptable non-harmful method of sample collection. Secondly, an increasing number of studies recommend cytology as an accurate test for diagnosing and subtyping canine lymphoma. Finally, the vast majority of canine lymphoma subtypes belong to 4-5 categories characterized by a typical cytological picture. Immunocytochemical staining of cytological smears gives new diagnostic possibilities, such as detection of markers better characterizing given growth or a potential goal for target therapy in individual cases (for example inhibitors of platelet-derived growth factor).

  2. Bacterial hydrodynamics

    2015-01-01

    Bacteria predate plants and animals by billions of years. Today, they are the world's smallest cells yet they represent the bulk of the world's biomass, and the main reservoir of nutrients for higher organisms. Most bacteria can move on their own, and the majority of motile bacteria are able to swim in viscous fluids using slender helical appendages called flagella. Low-Reynolds-number hydrodynamics is at the heart of the ability of flagella to generate propulsion at the micron scale. In fact, fluid dynamic forces impact many aspects of bacteriology, ranging from the ability of cells to reorient and search their surroundings to their interactions within mechanically and chemically-complex environments. Using hydrodynamics as an organizing framework, we review the biomechanics of bacterial motility and look ahead to future challenges.

    A 31-year-old nulliparous woman with severe diffuse uterine adenomyosis, which replaced nearly the whole uterine myometrium, visited our hospital due to severe dysmenorrhea, menorrhagia, and a desire to have a baby. The patient had a history of two spontaneous abortions. Laparotomic adenomyomectomy with transient occlusion of uterine arteries (TOUA) was performed safely and the patient tried in vitro fertilization and achieved a intrauterine twin pregnancy after recovery time of the operation. At 31+6 weeks of gestation, a male neonate baby weighing 1,620 g and a male neonate baby weighing 1,480 g were born by transverse lower segment cesarean delivery. There was no complication after the operation. The babies were discharged after receiving routine neonatal intensive care for neonatal respiratory distress syndrome. Adenomyomectomy with TOUA technique would be an option for conservative surgical treatment in patients with severe diffuse whole uterine adenomyosis. This is the first report of twin pregnancy after diffuse whole uterine adenomyomectomy with TOUA. PMID:27462599

    2016-03-01

    Bacterial infections of the endometrium after parturition commonly cause metritis and endometritis in dairy cattle, and these diseases are important because they compromise animal welfare and incur economic costs, as well as delaying or preventing conception. Here we highlight that uterine infections cause infertility, discuss which bacteria cause uterine disease, and review the evidence for mechanisms of inflammation and tissue damage in the endometrium. Bacteria cultured from the uterus of diseased animals include Escherichia coli, Trueperella pyogenes, and several anaerobic species, but their causative role in disease is challenged by the discovery of many other bacteria in the uterine disease microbiome. Irrespective of the species of bacteria, endometrial cell inflammatory responses to infection initially depend on innate immunity, with Toll-like receptors binding pathogen-associated molecular patterns, such as lipopolysaccharide and bacterial lipopeptides. In addition to tissue damage associated with parturition and inflammation, endometrial cell death is caused by a cholesterol-dependent cytolysin secreted by T. pyogenes, called pyolysin, which forms pores in plasma membranes of endometrial cells. However, endometrial cells surprisingly do not sense damage-associated molecular patterns, but a combination of infections followed by cell damage leads to release of the intracellular cytokine interleukin (IL)-1 alpha from endometrial cells, which then acts to scale inflammatory responses. To develop strategies to limit the impact of uterine disease on fertility, future work should focus on determining which bacteria and virulence factors cause endometritis, and understanding how the host response to infection is regulated in the endometrium.

    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. PMID:26969858

    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 ({beta}-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.

    Uterine stromal cell decidualization is an essential part of the reproductive process. Decidual tissue development requires a highly regulated control of the extracellular tissue remodeling; however the mechanism of this regulation remains unknown. Through systematic expression studies, we detected that Cbx4/2, Rybp, and Ring1B [components of polycomb repressive complex 1 (PRC1)] are predominantly utilized in antimesometrial decidualization with polyploidy. Immunofluorescence analyses revealed that PRC1 members are co-localized with its functional histone modifier H2AK119ub1 (mono ubiquitination of histone-H2A at lysine-119) in polyploid cell. A potent small-molecule inhibitor of Ring1A/B E3-ubiquitin ligase or siRNA-mediated suppression of Cbx4 caused inhibition of H2AK119ub1, in conjunction with perturbation of decidualization and polyploidy development, suggesting a role for Cbx4/Ring1B-containing PRC1 in these processes. Analyses of genetic signatures by RNA-seq studies showed that the inhibition of PRC1 function affects 238 genes (154 up and 84 down) during decidualization. Functional enrichment analyses identified that about 38% genes primarily involved in extracellular processes are specifically targeted by PRC1. Furthermore, ~15% of upregulated genes exhibited a significant overlap with the upregulated Bmp2 null-induced genes in mice. Overall, Cbx4/Ring1B-containing PRC1 controls decidualization via regulation of extracellular gene remodeling functions and sheds new insights into underlying molecular mechanism(s) through transcriptional repression regulation.

    International Nuclear Information System (INIS)

    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 × 10−3 mm2/s, and increased to 1.68 ± 0.24 × 10−3 mm2/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

    Background Ultrasound (US) is a popular method in the diagnosis and treatment of uterine leiomyomas, but the lack of accuracy greatly limits its application. Recently, microbubble enhancement technique affords direct depiction of tumor neovascularity and establishes a more precise vascular map of the tumor. This study was undertaken to describe the distribution patterns of SonoVue, a second-generation contrast agent, in the micrecirculation of uterine leiomyomas, and to investigate the potential use of contrast-enhanced ultrasound (CEUS) in the characterization and treatment of uterine leiomyomas.Methods Ninety-six patients with uterine leiomyomas were enrolled in this study. The CEUS was performed using cadence pulse sequencing technique (CPS) and SonoVue. Enhancement patterns of different lesions were observed.The diagnostic accuracy of CEUS was compared with that of conventional ultrasound.Results After contrast injection, vessels of macro- and micro-circulation of the myoma first appeared, followed by the normal myometrium and finally the endometrium. During the washout phase, the myoma exhibited homogeneous enhancement followed by apparent hypoenhancement. The margin of the tumor was depicted clearly. There was no agent perfusion in the benign degenerative or necrotic area. However in sarcomas degeneration, the feeding vessels appeared markedly earlier than those in myometrium. In addition, the tumor exhibited heterogeneous hyperenhancment with no agent perfusion in the center and no membraniform sign was observed in the late phase. In subserous andsubmucous leiomyomas, the feeding arteries in the pedicle arising from the uterine could be seen. In this study, the diagnostic accuracy of CEUS and conventional US for uterine leiomyomas was 96.7% (160/165) and 82.4% (136/165)respectively.Conclusions CEUS can provide a precise description of the leiomyomas vascularization. The specific enhancement pattern may be helpful for the characterization, treatment choice

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.

    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. Transcatheter arterial embolization is a safe and effective method of treating this disease

    Canine Herpesvirus (CHV) is being developed as a virus vector for the vaccination of European red foxes. However, initial studies using recombinant CHV vaccines in foxes revealed viral attenuation and lack of antibody response to inserted foreign antigens. These findings were attributed both to inactivation of the thymidine kinase (TK) gene and excess foreign genetic material in the recombinant viral genome. In this study, we report an improved CHV-bacterial artificial chromosome (BAC) vector system designed to overcome attenuation in foxes. A non-essential region was identified in the CHV genome as an alternative insertion site for foreign genes. Replacement of a guanine/cytosine (GC)-rich intergenic region between UL21 and UL22 of CHV with a marker gene did not change growth behaviour in vitro, showing that this region is not essential for virus growth in cell culture. We subsequently produced a CHV-BAC vector with an intact TK gene in which the bacterial genes and the antigen expression cassette were inserted into this GC-rich locus. Unlike earlier constructs, the new CHV-BAC allowed self-excision of the bacterial genes via homologous recombination after transfection of BACs into cell culture. The BAC-CHV system was used to produce a recombinant virus that constitutively expressed porcine zona pellucida subunit C protein between the UL21 and UL22 genes of CHV. Complete self-excision of the bacterial genes from CHV was achieved within one round of replication whilst retaining antigen gene expression. PMID:17079096

    The field of reproductive medicine witnessed a breakthrough in September 2014 with the first successful live birth post uterine transplantation. This success represents the culmination of decades' worth of research on infertility and reproductive medicine. This subject of infertility gathers special attention in the Middle East, as childbearing is given paramount importance in the family unit. And as with any new medical advancement, Middle Eastern people look to their religious authorities for guidance. This paper describes the various ethical quandaries related to uterine transplantation, from a perspective of the religious and societal factors that are unique to the Middle East, and embeds them within the conversation of its alternative solutions.

    Full Text Available Abnormal uterine bleeding (AUB is a common gynaecological problem with most common causes being fibroid, polyp, endometritis, neoplasia and coagulation disorder. Presence of retained intrauterine fetal bones as a cause of AUB, is a rare but well recognized entity. Patient may present with subfertility, secondary infertility, chronic pelvic pain, vaginal discharge, pelvic inflammatory disease, abnormal uterine bleeding. Incidence reported in literature is 0.15% among patients undergoing diagnostic hysteroscopy. Calcification appears as hyperechoeic area on ultrasound. Hysteroscopy guided removal of bony fragments is the gold standard and leads to complete resolution of symptoms. [Int J Reprod Contracept Obstet Gynecol 2016; 5(6.000: 2032-2033

    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.

    The remarkable elongated upper canines of extinct sabretoothed carnivorous mammals have been the subject of considerable speculation on their adaptive function, but the absence of living analogues prevents any direct inference about their evolution. We analysed scaling relationships of the upper canines of 20 sabretoothed feliform carnivores (Nimravidae, Barbourofelidae, Machairodontinae), representing both dirk-toothed and scimitar-toothed sabretooth ecomorphs, and 33 non-sabretoothed felids in relation to body size in order to characterize and identify the evolutionary processes driving their development, using the scaling relationships of carnassial teeth in both groups as a control. Carnassials display isometric allometry in both sabretooths and non-sabretooths, supporting their close relationship with meat-slicing, whereas the upper canines of both groups display positive allometry with body size. Whereas there is no statistical difference in allometry of upper canine height between dirk-toothed and scimitar-toothed sabretooth ecomorphs, the significantly stronger positive allometry of upper canine height shown by sabretooths as a whole compared to non-sabretooths reveals that different processes drove canine evolution in these groups. Although sabretoothed canines must still have been effective for prey capture and processing by hypercarnivorous predators, canine morphology in these extinct carnivores was likely to have been driven to a greater extent by sexual selection than in non-sabretooths. Scaling relationships therefore indicate the probable importance of sexual selection in the evolution of the hypertrophied sabretooth anterior dentition. PMID:23951334

    Seroepidemiological studies on canine leishmaniasis in Bulgaria, even in areas where human leishmaniasis has been detected, are controversial. This report describes 2 clinical cases of canine visceral leishmaniasis. The disease was confirmed by microscopical, serological, and molecular methods. It is, therefore, suggested that infected dogs could constitute the reservoir for human leishmaniasis in the country.

    2013-12-01

    This clinical article reports a technique, apicotomy, for managing dilacerated or ankylosed canines. The records of 3 patients successfully treated with apicotomy are presented. Orthodontists observe clinically significant incidences of impacted maxillary canines in their daily practices. Several procedures have been described to bring an ankylosed, impacted tooth into occlusion. Luxation is the most widely used solution, but there are risks involved with that approach, and the success rate is low. Surgical repositioning has also been used, but morbidity is high, and the aggressiveness of the procedure might also contraindicate it. Ankylosis might be related to the anatomic position of the canine's root apex and its adjacent anatomic structures. Apicotomy is a guided fracture of a canine root apex, followed by its orthodontic traction. It is a conservative surgical alternative for treating impacted canines with dilacerations or apical root ankylosis. PMID:24286914

  8. Pregnancy Following Uterine Artery Embolization with Polyvinyl Alcohol Particles for Patients with Uterine Fibroid or Adenomyosis

    International Nuclear Information System (INIS)

    Purpose:To determine whether uterine fibroid embolization (UFE) with polyvinyl alcohol (PVA) particles affects fertility in women desiring future pregnancy.Methods:Of 288 patients managed with UFE with PVA particles for uterine myoma or adenomyosis between 1998 and 2001, 94 patients were enrolled in this study. The age range of participants was 20-40 years. The data were collected through review of medical records and telephone interviews. Mean duration of follow-up duration was 35 months (range 22-60 months). Patients using contraception and single women were excluded, and the chance of infertility caused by possible spousal infertility or other factors was disregarded. Contrast-enhanced magnetic resonance imaging was performed in all patients before and after UFE, and the size of PVA particles used was 255-700 μm.Results:Among 94 patients who underwent UFE with PVA, 74 were on contraceptives, 6 had been single until the point of interview, and 8 were lost to follow-up. Of the remaining 6 patients who desired future pregnancy, 5 (83%) succeeded in becoming pregnant (1 patient became pregnant twice). Of a total of 8 pregnancies, 6 were planned pregnancies and 2 occurred after contraception failed. Five deliveries were vaginal, and 2 were by elective cesarean. Artificial abortion was performed in 1 case of unplanned pregnancy. There was 1 case of premature rupture of membrane (PROM) followed by preterm labor and delivery of an infant who was small-for-gestational-age. After UFE, mean volume reduction rates of the uterus and fibroid were 36.6% (range 0 to 62.6%) and 69.3% (range 36.3% to 93.3%), respectively.Conclusion:Although the absolute number of cases was small, UFE with PVA particles ultimately did not affect fertility in the women who underwent the procedure

    Background. It is widely assumed that the uterine cavity in non-pregnant women is physiologically sterile, also as a premise to the long-held view that human infants develop in a sterile uterine environment, though likely reflecting under-appraisal of the extent of the human bacterial metacommunity. In an exploratory study, we aimed to investigate the putative presence of a uterine microbiome in a selected series of non-pregnant women through deep sequencing of the V1-2 hypervariable region of the 16S ribosomal RNA (rRNA) gene. Methods. Nineteen women with various reproductive conditions, including subfertility, scheduled for hysteroscopy and not showing uterine anomalies were recruited. Subjects were highly diverse with regard to demographic and medical history and included nulliparous and parous women. Endometrial tissue and mucus harvesting was performed by use of a transcervical device designed to obtain endometrial biopsy, while avoiding cervicovaginal contamination. Bacteria were targeted by use of a barcoded Illumina MiSeq paired-end sequencing method targeting the 16S rRNA gene V1-2 region, yielding an average of 41,194 reads per sample after quality filtering. Taxonomic annotation was pursued by comparison with sequences available through the Ribosomal Database Project and the NCBI database. Results. Out of 183 unique 16S rRNA gene amplicon sequences, 15 phylotypes were present in all samples. In some 90% of the women included, community architecture was fairly similar inasmuch B. xylanisolvens, B. thetaiotaomicron, B. fragilis and an undetermined Pelomonas taxon constituted over one third of the endometrial bacterial community. On the singular phylotype level, six women showed predominance of L. crispatus or L. iners in the presence of the Bacteroides core. Two endometrial communities were highly dissimilar, largely lacking the Bacteroides core, one dominated by L. crispatus and another consisting of a highly diverse community, including Prevotella spp

    Infectious endometritis is a major cause of infertility in the mare and inflicts major losses on the equine breeding industry. The ability of the mare to eliminate uterine infections has been studied intensively for decades; however, despite identification of several factors contributing to the multifactorial pathogenesis and improved treatment, infectious endometritis remains a significant problem in a subpopulation of broodmares. Streptococcus equi subsp. zooepidemicus (S. zooepidemicus) is one of the most commonly isolated pathogens from the uterus of mares, suffering from infectious endometritis. Its ability to cause chronic latent infection by residing deep within the endometrial tissue has previously been described. The aim of the present study was to correlate different mare risk factors to infectious endometritis and pregnancy rates in broodmares and to investigate whether clonal or genetically distinct S. zooepidemicus strains isolated from mares with endometritis were associated with mare risk factors and the outcome of insemination. Mares (N = 152) were examined after natural cover, and 20% (31 mares) had intrauterine fluid (IUF) accumulation. Fifty-five percent (16 of 29) of the mares with IUF had infectious endometritis, and S. zooepidemicus was isolated in 81% (13 of 16) of these mares. Significantly more resting mares had IUF compared with foaling mares, and the foaling mares had the highest prevalence of positive bacterial growth from the uterine swab. The per-cycle pregnancy rate for the study was 63%. Pregnancy rate was significantly negatively affected by increased age (>12 years) and increased parity (>4), and the lowest pregnancy rate was observed in resting mares compared with foaling, barren, and maiden mares. Up to four S. zooepidemicus isolates were selected from each mare with growth of S. zooepidemicus from the uterine swab sample and further characterized by pulsed-field gel electrophoresis. In total, S. zooepidemicus isolates from

  13. Role of MRI in detecting involvement of the uterine internal os in uterine cervical cancer: Systematic review of diagnostic test accuracy

    International Nuclear Information System (INIS)

    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

    Herein is presented a fertility-preserving approach in the management of a uterine arteriovenous malformation (AVM) resistant to endovascular management. The patient had a documented AVM and underwent 2 uterine artery embolization procedures, with subsequent recurrence of symptoms. Doppler ultrasound demonstrated recanalization of the AVM. Ultimately, laparoscopic resection of the AVM was performed after laparoscopic ligation of the uterine arteries. Postoperatively, the patient has remained asymptomatic. Laparoscopic resection of a uterine AVM may offer a fertility-preserving alternative to hysterectomy in patients in whom endovascular management has failed. PMID:25117839

    Full Text Available Background: Abnormal uterine bleeding is one of the commonest complaints in women and when it occurs without organic lesions like tumor, inflammation, it is called as dysfunctional uterine bleeding. Aim of current study was to find out the histopathological pattern of endometrium in Abnormal Uterine Bleeding (AUB also to study organic causes of AUB. Methods: Specimens received as endometrial curettage and hysterectomy specimens were studied followed by correlation of histopathology with age and clinical presentation. Results: The patients were mainly from the age group of 30-49 years (74.24%. The most common menstrual disorder was menorrhagia (46.86%. In dysfunctional uterine bleeding the most common histological pattern of endometrium includes proliferative endometrium (22.8% followed by endometrial hyperplasia (19.40%, atrophic endometrium (7.16%, secretory endometrium (5.97%, irregular shedding [1.80%], irregular ripening (1.20% and anovulatory endometrium (0.59%. Organic lesions encountered in AUB cases were leiomyoma (17.92%, endometrial polyp (1.79%, endometrial carcinoma (1.50%, endometriosis (0.59% and choriocarcinoma (0.29%. Conclusion: It is important to know the histological pattern of the endometrium like proliferative endometrium, endometrial hyperplasia, atrophic endometrium, secretory endometrium, irregular ripening and shredding and organic lesions in patients diagnosed as AUB in different age groups since recognition of these conditions will help and will avoid further complications.

    Objective: To approach the cause of radiation induced enterocolitis and its relationship with retropostion of the uterus in uterine cervical cancer after radiotherapy. Methods: Twenty-two patients with radiation induced enterocolitis, from 212 patients with uterine cervical cancer who had received radio-therapy during 2002-2005, were retrospectively analyzed. The incidence between patients with anteposition and patients with retroposition of uterus was compared. The distance between uterine central axis and the rectum of 15 patients with anteposition and 15 patients with retroposition of the uterus was measured, as well as the uterus retroversional flexion angle of the retropositioned uterus. Results: The incidence of radiation enterocolitis in patients with retroposition of uterus was obviously higher than that in patients with anteposition (χ2=21.10, P<0.01). The distance between point C and the rectum in patients with retroposition of uterus was shorter(t=7.33, P<0.05). The retroversional flexion angle of retropostitioned uterus were between 9-22 degree with a median angle of 17 degree. Conclusion: The incidence of radiation induced enterocolitis is higher in patients with retropostition of uterus after radiotherapy, because the distance between the uterine central axis and the rectum is shorter. The y axis and z axis often form an acute angle in the rectal direction during after-loading therapy, which would had led to an excessive dose to the rectum. (authors)

  1. Risk and complication rate of uterine fibroid embolization (UFE)

    International Nuclear Information System (INIS)

    Our goal was to evaluate risks and complication rate of uterine fibroid embolization (UFE). The most frequent complications reported in the literature are associated with angiography procedure, serious complications are extremely infrequent. The embolization of fibroids is a safe angiographic intervention. Nevertheless, the interventional radiologist must be aware of the common risks and complication and the strategies to avoid them.

    Full Text Available Uterine fibroids are common in women of reproductive age and various conservative treatments are available. In order to achieve a successful conservative treatment of fibroids, functional integrity of the uterus is as important as tumor removal or symptoms relief. In this context, intrauterine adhesions must be recognized as a possible complication of conservative management of uterine fibroids, but diagnostic pitfalls might justify an underestimation of their incidence. Hysteroscopic myomectomy can cause adhesions as a result of surgical trauma to the endometrium. The average reported incidence is around 10% at second-look hysteroscopy, but it is higher in certain conditions, such as the case of multiple, apposing fibroids. Transmural myomectomies also have the potential for adhesion, especially when combined with uterine ischemia. Uterine arteries embolization also carries a risk of intracavitary adhesions. Prevention strategies including bipolar resection, barrier gel or postoperative estradiol, might be useful, but stronger evidence is needed. In view of current knowledge, we would recommend a prevention strategy based on a combination of surgical trauma minimization and identification of high-risk cases. Early hysteroscopic diagnosis and lysis possibly represents the best means of secondary prevention and treatment of postoperative intrauterine adhesions.

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.

    Primary abdominal pregnancy is an extremely rare type of extrauterine pregnancy. It has been reported from many unusual intra-abdominal sites. We report a case of primary abdominal pregnancy following intra-uterine insemination (not reported earlier to our knowledge). Implanted on the anterior surface of the uterus possibly related to an endometriotic foci. Early diagnosis enabled laparoscopic management of this case.

  7. Extraglandular and intraglandular vascularization of canine prostate.

    The literature on the vascularization of the canine prostate is reviewed and the clinical significance of prostate morphology is described. Scanning Electron Microscopy (SEM), combined with improved corrosion casting methods, reveal new morphological details that promise better diagnostics and treatment but also require expansion of clinical nomenclature. A proposal is made for including two previously unnamed veins in Nomina Anatomica Veterinaria (NAV). The canine prostate has two lobes with independent vascularization. Each lobe is supplied through the left and right a. prostatica, respectively. The a. prostatica sprouts three small vessels (cranial, middle, and caudal) towards the prostate gland. A. prostatica is a small-size artery whose wall structure is similar to the arteries of the muscular type. V. prostatica is a small-size valved vein. The canine prostate has capsular, parenchymal, and urethral vascular zones. The surface vessels of the capsule are predominantly veins and the diameter of arterial vessels is larger than that of the veins. The trabecular vessels are of two types: direct and branched. The prostate parenchyma is supplied by branches of the trabecular vessels. The periacinary capillaries are fenestrated and form a net in a circular pattern. The processes of the myoepithelial cells embrace both the acins and the periacinar capillaries. In the prostate ductal system. there are spermatozoa. The prostatic part of the urethra is supplied by an independent branch of a. prostatica. The prostatic urethral part is drained by v. prostatica, the vein of the urethral bulb and the ventral prostate veins. M. urethralis begins as early as the urethral prostatic part. The greater part of the white muscle fibers in m. urethralis suggest an enhanced anaerobic metabolism. PMID:14988915

    This paper describes changes in spontaneous myometrial activity around estrus, factors that affect myometrial activity, and the possible role of uterine contractions in the process of (artificial) insemination, sperm transport and fertilization. Myometrial activity in the sow increases during estrus. The activity is myogenic in origin, but several factors have been shown to affect myometrial activity. Natural mating stimulates uterine contractions through several mechanisms. The presence of a boar, rather than the act of mating, induces central oxytocin release in the sow and thus increases uterine activity. Estrogens in the ejaculate of a boar can trigger prostaglandin release by the endometrium and thus increase uterine activity. Tactile stimulation of the genital tract (cervix) or tactile stimulation of the back and flanks of the sow during artificial insemination does not cause a release of oxytocin. There is hardly any evidence for the effects of these latter stimuli on uterine activity, and if they are present at all, the effects are very small. Evidence for the effects of synthetic boar odor on oxytocin release and/or uterine activity is inconsistent. The mere presence of a boar during insemination, in contrast, clearly stimulates uterine activity through the release of oxytocin. Hormonal stimulation (intrauterine) of uterine activity with estrogens, prostaglandins, or oxytocins before, during or after insemination generally improves fertilization rate, especially in situations with reduced fertility. Therefore, uterine contractions are believed to play an important role in the transport of sperm cells to the oviducts after insemination. Whether uterine contractions are absolutely necessary for sperm transport through the uterine horns, however, is not clear. Intensive stimulation of uterine contractions using hormones can also reduce the fertilization rate, probably by increasing the reflux of sperm cells during insemination. In this respect, the presence

    Glaucoma is a common ocular condition in humans and dogs leading to optic nerve degeneration and irreversible blindness. Primary glaucoma is a group of spontaneous heterogeneous diseases. Multiple factors are involved in its pathogenesis and these factors vary across human ethnic groups and canine breeds, so the clinical phenotypes are numerous and their classification can be challenging and remain superficial. Aging and oxidative stress are major triggers for the manifestation of disease. Multiple, intertwined inflammatory and biochemical cascades eventually alter cellular and extracellular physiology in the optic nerve and trabecular meshwork and lead to vision loss. PMID:26456751

    A canine model of distal limb lymphedema was established in order to study the treatment of this condition by lymph node transfer. This model was more difficult to establish than whole-limb lymphedema. Significant edema was achieved by a combination of preoperative irradiation and circumferential removal of skin from the irradiated areas followed by removal of the contents of the popliteal fossa. Despite these measures, it was not possible to produce lymphedema in every case, possibly because of the presence of lymphaticovenous shunts and panvascular compensation mechanisms.

    In this study, we provide the first comprehensive annotation of canine interferon-λ (CaIFN-λ, type III IFN). Phylogenetic analysis based on genomic sequences indicated that CaIFN-λ is located in the same branch with Swine IFN-λ1 (SwIFN-λ), Bat IFN-λ1 (BaIFN-λ), and human IFN-λ1 (HuIFN-λ1). CaIFN-λ was cloned, expressed in Escherichia coli, and purified to further investigate the biological activity in vitro. The recombinant CaIFN-λ (rCaIFN-λ) displayed potent antiviral activity on both homologous and heterologous animal cells in terms of inhibiting the replication of the New Jersey serotype of vesicular stomatitis virus (VSV), canine parvovirus, and influenza virus A/WSN/33 (H1N1), respectively. In addition, we also found that rCaIFN-λ exhibits a significant antiproliferative response against A72 canine tumor cells and MDCK cells in a dose-dependent manner. Furthermore, CaIFN-λ activated the JAK-STAT signaling pathway. To evaluate the expression of CaIFN-λ induced by virus and the expression of IFN-stimulated genes (ISGs) induced by rCaIFN-λ in the MDCK cells, we measured the relative mRNA level of CaIFN-λ and ISGs (ISG15, Mx1, and 2'5'-OAS) by quantitative real-time PCR and found that the mRNA level of CaIFN-λ and the ISGs significantly increased after treating the MDCK cells with viruses and rCaIFN-λ protein, respectively. Finally, to evaluate the binding activity of rCaIFN-λ to its receptor, we expressed the extracellular domain of the canine IFN-λ receptor 1 (CaIFN-λR1-EC) and determined the binding activity via ELISA. Our results demonstrated that rCaIFN-λ bound tightly to recombinant CaIFN-λR1-EC (rCaIFN-λR1-EC). PMID:24950142

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

    Full Text Available Abstract Background Contamination of the uterine lumen with bacteria is ubiquitous in cattle after parturition. Some animals develop endometritis and have reduced fertility but others have no uterine disease and readily conceive. The present study tested the hypothesis that postpartum cattle that develop persistent endometritis and infertility are unable to limit the inflammatory response to uterine bacterial infection. Methods Endometrial biopsies were collected several times during the postpartum period from animals that were subsequently infertile with persistent endometritis (n = 4 or had no clinical disease and conceived to first insemination (n = 4. Quantitative PCR was used to determine the expression of candidate genes in the endometrial biopsies, including the Toll-like receptor (TLR 1 to 10 family of innate immune receptors, inflammatory mediators and their cognate receptors. Selected proteins were examined by immunohistochemistry. Results The expression of genes encoding pro-inflammatory mediators such as interleukins (IL1A, IL1B and IL6, and nitric oxide synthase 2 (NOS2 were higher during the first week post partum than subsequently. During the first week post partum, there was higher gene expression in infertile than fertile animals of TLR4, the receptor for bacterial lipopolysaccharide, and the pro-inflammatory cytokines IL1A and IL1B, and their receptor IL1R2. The expression of genes encoding other Toll-like receptors, transforming growth factor beta receptor 1 (TGFBR1 or prostaglandin E2 receptors (PTGER2 and PTGER4 did not differ significantly between the animal groups. Gene expression did not differ significantly between infertile and fertile animals after the first week postpartum. However, there were higher ratios of IL1A or IL1B mRNA to the anti-inflammatory cytokine IL10, during the first week post partum in the infertile than fertile animals, and the protein products of these genes were mainly localised to the epithelium

  15. Evaluation of uterine adenomyosis by magnetic resonance imaging

    International Nuclear Information System (INIS)

    To assess the capability of magnetic resonance imaging (MR imaging) to enable the detection of the characteristic findings of uterine adenomyosis, 50 pathologically proved adenomyosis lesions (27 cases accompanied with uterine myoma) were chosen and their MRI findings were reviewed. MR imaging was performed with a superconducting magnet, Magnex 150/HP ( 1.5 Tesla), 100 ( 1.0 Tesla) and α (0.5 Tesla). When both T1-weighted images and T2-weighted images were analyzed, the detection rate of adenomyosis was 82%. In 9 cases (18%), adenomyosis was not detected, due to motion artifact in 2 cases, diffuse hypointensity of the myometrium in 3 cases and distortion of the endometrium by myoma node in 4 cases. On the T1-weighted image, adenomyosis was detected as an enlarged uterus with a smooth external configuration in 20%, within half of which high signal intensity spots representing islands of menstrual hemorrhagic areas were seen. A specific diagnosis of adenomyosis could be made in those cases. On the T2-weighted image, high signal intensity spots (thought to represent heterotopic endometrium) were seen in 46%. On the T2-weighted image, adenomyosis was demonstrated as thickening of the junctional zone (JZ) extending through the myometrium in 80%. Dynamic enhanced MR imaging was performed in 5 cases, 4 of which were accompanied with uterine myoma. Adenomyosis showed sparse contrast enhancement in the early phase, while uterine myoma had no morked enhancement in the early phase but became gradually enhanced in the late phase. In conclusion, MR imaging is useful for detection of adenomyosis. However, when it is difficult to detect adenomyosis or to distinguish it from uterine myoma, dynamic enhanced MR imagings may provide more useful information. (author)

    Foxl2 codes for a forkhead/HNF3 transcription factor essential for follicular maturation and maintenance of ovarian identity. FOXL2 mutations are associated with Blepharophimosis, Ptosis and Epicanthus inversus Syndrome (BPES) characterized by eyelid malformations (types I and II) and premature ovarian insufficiency (type I). We show that Foxl2 is not only expressed by the ovary, but also by other components of the mouse female reproductive tract, including the uterus, the cervix and the oviduct. In the uterus, Foxl2 expression is first observed in the neonatal mesenchyme and, during uterine maturation, persists in the stroma and in the deep inner myometrial layer (IML). In the adult, Foxl2 is expressed in the differentiated stromal layer, but no longer in the myometrium. Conditional deletion of Foxl2 in the postnatal (PN) uterus using Progesterone Receptor-cre (Pgr(cre/+)) mice results in infertility. During PN uterine maturation Pgr(cre/+); Foxl2(flox/flox) mice present a severely reduced thickness of the stroma layer and an hypertrophic, disorganized IML. In adult Pgr(cre/+); Foxl2(flox/flox) mice a supplementary muscular layer is present at the stroma/myometrium border and vascular smooth muscle cells fail to form a coherent layer around uterine arteries. Wnt signalling pathways play a central role in uterine maturation; in Pgr(cre/+); Foxl2(flox/flox) mice, Wnt genes are deregulated suggesting that Foxl2 acts through these signals. In humans, thickening of the IML (also called "junctional zone") is associated with reduced fertility, endometriosis and adenomyosis. Our data suggest that Foxl2 has a crucial role in PN uterine maturation and could help to understand sub-fertility predisposition in women. PMID:25687138

    Embryonic mortality in cows is at least in part caused by failure of pregnancy recognition (PR). Evidence has shown that bovine viral diarrhoea virus (BVDV) infection can disrupt pregnancy. Prostaglandins (PG) play important roles in many reproductive processes, such as implantation. The aim of this study was to investigate the effect of BVDV infection on uterine PG production and PR using an in vitro PR model. Bovine uterine endometrial cells isolated from ten BVDV-free cows were cultured and treated with 0 or 100ng/mL interferon-τ (IFNT) in the absence or presence of non-cytopathic BVDV (ncpBVDV). PGF2α and PGE2 concentrations in the spent medium were measured using radioimmunoassays, and in the treated cells expression of the genes associated with PG production and signalling was quantified using qPCR. The results showed that the IFNT challenge significantly stimulated PTGS1 and PTGER3 mRNA expression and PGE2 production; however, these stimulatory effects were neutralised in the presence of ncpBVDV infection. ncpBVDV infection significantly increased PTGS1 and mPGES1 mRNA expression and decreased AKR1B1 expression, leading to increased PGE2 and decreased PGF2α concentrations and an increased PGE2:PGF2α ratio. The other tested genes, including PGR, ESR1, OXTR, PTGS2, PTGER2 and PTGFR, were not significantly altered by IFNT, ncpBVDV or their combination. Our study suggests that BVDV infection may impair PR by (1) inhibiting the effect of IFNT on uterine PG production and (2) inducing an endocrine switch of PG production from PGF2α to PGE2 to decrease uterine immunity, thereby predisposing the animals to uterine disease.

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

    International Nuclear Information System (INIS)

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

  20. 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

    Adenovirus (Ad) derived vectors have been widely used for short or long-term gene transfer, both for gene therapy and vaccine applications. Because of the frequent pre-existing immunity against the classically used human adenovirus type 5, canine adenovirus type 2 (CAV2) has been proposed as an alternative vector for human gene transfer. The well-characterized biology of CAV2, together with its ease of genetic manipulation, offer major advantages, notably for gene transfer into the central nervous system, or for inducing a wide range of protective immune responses, from humoral to cellular immunity. Nowadays, CAV2 represents one of the most appealing nonhuman adenovirus for use as a vaccine vector. This protocol describes a simple method to construct, produce and titer recombinant CAV2 vectors. After cloning the expression cassette of the gene of interest into a shuttle plasmid, the recombinant genomic plasmid is obtained by homologous recombination in the E. coli BJ5183 bacterial strain. The resulting genomic plasmid is then transfected into canine kidney cells expressing the complementing CAV2-E1 genes (DK-E1). A viral amplification enables the production of a large viral stock, which is purified by ultracentrifugation through cesium chloride gradients and desalted by dialysis. The resulting viral suspension routinely has a titer of over 10(10) infectious particles per ml and can be directly administrated in vivo. PMID:24326926

  2. Cone beam computed tomography findings of impacted upper canines

    International Nuclear Information System (INIS)

    To describe the features of impacted upper canines and their relationship with adjacent structures through three-dimensional cone-beam computed tomography (CBCT) images. Using the CBCT scans of 79 upper impacted canines, we evaluated the following parameters: gender, unilateral/bilateral occurrence, location, presence and degree of root resorption of adjacent teeth (mild, moderate, or severe), root dilaceration, dental follicle width, and presence of other associated local conditions. Most of the impacted canines were observed in females (56 cases), unilaterally (51 cases), and at a palatine location (53 cases). Root resorption in adjacent teeth and root dilaceration were observed in 55 and 47 impacted canines, respectively. In most of the cases, the width of the dental follicle of the canine was normal; it was abnormally wide in 20 cases. A statistically significant association was observed for all variables, except for root dilaceration (p=0.115) and the side of impaction (p=0.260). Root resorption of adjacent teeth was present in most cases of canine impaction, mostly affecting adjacent lateral incisors to a mild degree.

    To describe the features of impacted upper canines and their relationship with adjacent structures through three-dimensional cone-beam computed tomography (CBCT) images. Using the CBCT scans of 79 upper impacted canines, we evaluated the following parameters: gender, unilateral/bilateral occurrence, location, presence and degree of root resorption of adjacent teeth (mild, moderate, or severe), root dilaceration, dental follicle width, and presence of other associated local conditions. Most of the impacted canines were observed in females (56 cases), unilaterally (51 cases), and at a palatine location (53 cases). Root resorption in adjacent teeth and root dilaceration were observed in 55 and 47 impacted canines, respectively. In most of the cases, the width of the dental follicle of the canine was normal; it was abnormally wide in 20 cases. A statistically significant association was observed for all variables, except for root dilaceration (p=0.115) and the side of impaction (p=0.260). Root resorption of adjacent teeth was present in most cases of canine impaction, mostly affecting adjacent lateral incisors to a mild degree. A wide dental follicle of impacted canines was not associated with a higher incidence of external root resorption of adjacent teeth.

  4. Early ultrasonographic findings after a uterine fibroid embolization: the value of differentiate from procedure-related uterine infection

    International Nuclear Information System (INIS)

    To evaluate the early ultrasonographic (US) findings from the uterus and myoma after a uterine fibroid embolization (UFE). From March 2004 to January 2006, eleven patients (27-48 years, mean:37 years) with UFE to treat symptomatic uterine myoma, were retrospectively reviewed. A serial follow up gray-scale and color Doppler US were performed from one day to two weeks following a UFE. The US findings were evaluated for the presence and distribution pattern of air, time of air loss, and presence of fluid collection in the uterine cavity and color Doppler (SD Comment: Doppler is name. Should perhaps be upper case) signal. Numerous high echoes with reverberation artifacts (which suggest air), were observed within the myoma (in all cases), one day after UFE. A branching linear echo pattern was observed in 4 cases (36%), whereas scattered echoes were observed in 7 cases (64%). Progressive loss of air, within 7 days of a UFE, was observed in 9 cases (82%), whereas 2 cases (12%) were observed within 14 days of a UFE. Abnormal fluid collection in the uterine cavity and a color Doppler signal within the myoma was not observed for all cases. Branching or scattered echoes (suggesting air), are normally found within the myoma after a UFE, but these echoes disappeared within 2 weeks. These early US findings can be useful in differentiating from myoma infections after a UFE

    Full Text Available Aim. To describe a new technique of uterine manipulation in laparoscopic management of pelvic cancers. Material and Methods. We used a novel uterine hitch technique in 23 patients from May 2008 to October 2008. These patients underwent pelvic oncologic surgery including laparoscopic radical hysterectomy (n=7, laparoscopic anterior resection (n=4, laparoscopic abdominoperineal resection (n=3, laparoscopic posterior exenteration (n=4, or laparoscopic anterior exenteration (n=5. The uterus was hitched to the anterior abdominal.wall by either a single suture in the fundus or by sutures through the round ligaments. Results. The uterine hitch technique was successfully accomplished in all procedures. It was performed in less than 5 minutes in all cases. It obviated the need for vaginal manipulation. An extra port for retraction could be avoided. There were no intraoperative complications. Conclusion. A practical, cheap and reproducible method for uterine manipulation, during pelvic oncologic surgery is described. It improves the stability of the uterus and also obviates the need for keeping an additional assistant for vaginal manipulation in any of the procedures.

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

    Objective:To establish a sensitized canine model for kidney transplantation. Methods:12 male dogs were averagely grouped as donors and recipients. A small number of donor canine lymphocytes was infused into different anatomic locations of a paired canine recipient for each time and which was repeated weekly. Specific immune sensitization was monitored by means of Complement Dependent Cytotoxicity (CDC) and Mixed Lymphocyte Culture (MLC) test. When CDC test conversed to be positive and MLC test showed a significant proliferation of reactive lymphocytes of canine recipients, the right kidneys of the paired dogs were excised and transplanted to each other concurrently. Injury of renal allograft function was scheduled determined by ECT dynamic kidney photography and pathologic investigation. Results :CDC test usually conversed to be positive and reactive lymphocytes of canine recipients were also observed to be proliferated significantly in MLC test after 3 to 4 times of canine donor lymphocyte infusions. Renal allograft function deterioration occurred 4 d post-operatively in 4 of 6 canine recipients, in contrast to none in control dogs. Pathologic changes suggested antibody-mediated rejection (delayed) or acute rejection in 3 excised renal allograft of sensitized dogs. Seven days after operation, all sensitized dogs had lost graft function, pathologic changes of which showed that the renal allografts were seriously rejected. 2 of 3 dogs in control group were also acutely rejected. Conclusion:A convenient method by means of repeated stimulation of canine lymphocyte may induce specific immune sensitization in canine recipients. Renal allografts in sensitized dogs will be earlier rejected and result in a more deteriorated graft function.

    Full Text Available Canine babesiosis is a relatively frequent disease in Croatia. Elevated body temperature, anemia and haemoglobinuria are the most common signs. Diagnosis is rapidly obtained by employing blood smears, as B. canis is present in the red blood cells of affected dogs. Treatment is favourable and without consequences. Blood work was performed initialy, prior to treatment, and on the 1st and the 7th day following treatment. Following history and examination of the dogs blood and urine samples were taken. After confirmation of B. canis in the red blood cells, alltogether 226 dogs were tretated. Out of them 80 were tretaed with Berenil® (diminazen aceturate, Hoechst, 72 were tretated with Imizol® (imidocarb dipropionate, Schering-Plough-Animal-Health and 74 with Oxopirvedin® (fenamidine dizetionate, Merial. Clinical findings, haematological analysis and urine analysis are given and statistically assesed. After tretment with Berenil®, symptoms of babesiosis regressed within 24 hours. Health improved more slowly in the group treated with Oxopirvedin® in comparioson with the group treated with Berenil®. Contrary to the above, Imizol® displayed the slowest regression of the disease and reinfestation with B. canis within 30 days was not noted. That is not the case if treatment was provided by Berenil® and Oxopirvedin®. In all 226 cases of canine babesiosis side effects were not noted, except topically inflammed tissue at the site of subcutaneous application.

A total of 209 local, cross breed and breed dogs sera from Kodya Bogor, Kabupaten Bogor, Sukabumi, and Jakarta, had been tested using Haemagglutination Inhibition Test (HI with pig red blood cells. A total of 64 breed and cross breed dogs from Sukabumi and Kodya Bogor, were used as a sentinel dogs to study the epidemiology of Canine parvovirus (CPV infection and its immunological responses caused by vaccination. The results indicated that 78% (95 breed and cross bred dogs and 59% (51 local dogs had antibody to CPV. Sentinel dogs results indicated that dogs had been vaccinated showed antibody response with the varied titre dependant upon prevaccination titre. Low prevaccinated titre gave better response than protective level titre. From 19 puppies observed, Maternal antibodi were still detected until 5 weeks old puppies. First vaccination given at less than 3 months old, should be boosted after 3 months old puppied. Antibodi titre produced by natural infection will keep untill 2 years. These data concluded that the dog condition and time of vaccination will affect the optimum antibody response.

N. caninum has a heteroxenous life cycle and affects a wide range of warm-blooded animals. The domestic and wild canids are the definitive host of the parasite. They shed oocysts after ingestion of tissue cysts from infected intermediate hosts (ovine, equine, bovine, canine, and many other species, containing bradyzoites, or oocyst-contaminated water and food. The presence of dogs in farms is considered a risk factor for production animals. A wide range of diagnostic methods are currently available, but the most used is serology, ie, indirect fluorescent antibody test specific to the antibody detection in blood serum samples. No vaccine is available, but control strategies should be focused on the vertical and horizontal transmission of the parasite, ie, avoid feeding dogs with raw or undercooked meat, and taking care with water for human and animal consumption. No medicines to control the transplacental transmission are available yet. Keywords: neosporosis, Neospora caninum, pathogenesis, management, dogs

    Full Text Available The derivation of canine embryonic stem cells and generation of canine induced pluripotent stem cells are significant achievements that have unlocked the potential for developing novel cell-based disease models, drug discovery platforms and transplantation therapies in the dog. A progression from concept to cure in this clinically relevant companion animal will not only help our canine patients but also help advance human regenerative medicine. Nevertheless, many issues remain to be resolved before pluripotent cells can be used clinically in a safe and reproducible manner.

  14. The utility of diffusion-weighted MR imaging in differentiation of uterine adenomyosis and leiomyoma

    International Nuclear Information System (INIS)

    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 mm2/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 mm2/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 mm2/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.

    2002-07-01

    Full Text Available Wild dogs Lycaon pictus (n = 8 were vaccinated 4 times against canine distemper (n = 8 (initially with inactivated and subsequently with live attenuated strains of canine distemper and canine parvovirus infection (n = 8 over a period of 360 days. Four of the wild dogs were also vaccinated 3 times against rabies using a live oral vaccine and 4 with an inactivated parenteral vaccine. Commercially-available canine distemper, canine parvovirus and parenteral rabies vaccines, intended for use in domestic dogs, were used. None of the vaccinated dogs showed any untoward clinical signs. The inactivated canine distemper vaccine did not result in seroconversion whereas the attenuated live vaccine resulted in seroconversion in all wild dogs. Presumably protective concentrations of antibodies to canine distemper virus were present in all wild dogs for at least 451 days. Canine parvovirus haemagglutination inhibition titres were present in all wild dogs prior to the administration of vaccine and protective concentrations persisted for at least 451 days. Vaccination against parvovirus infection resulted in a temporary increase in canine parvovirus haemagglutination inhibition titres in most dogs. Administration of both inactivated parenteral and live oral rabies vaccine initially resulted in seroconversion in 7 of 8 dogs. These titres, however, dropped to very low concentrations within 100 days. Booster administrations resulted in increased antibody concentrations in all dogs. It was concluded that the vaccines were safe to use in healthy subadult wild dogs and that a vaccination protocol in free-ranging wild dogs should at least incorporate booster vaccinations against rabies 3-6 months after the first inoculation.

    Objective: To update the recent knowledge of the microbiological causes of canine otitis externa in Campania Region (Italy) and the antibiotic susceptibility patterns of the iso-lated strains. Methods: A total of 122 dogs were examined by otoscopy, and auricular swab samples were collected from both ears in 74 dogs presenting clinical bilateral otitis and from single ears in 48 dogs displaying clinical unilateral otitis. Cytological examination, bacteriological analysis and antimicrobial susceptibility tests were performed. Results: Thirty-one out of 122 dogs were positive for yeast species (25.4%, 95% con-fidence interval (CI): 18.2%–34.2%) with a higher prevalence of Malassezia pachy-dermatis (21/31 isolates, 67.7%, CI: 48.5%–82.7%), and a total of 91 out of 122 dogs were positive for bacterial species (74.6%;CI:65.8%–81.8%) with a higher prevalence of Staphylococcus pseudintermedius (45/143 isolates, 31.5%, CI: 24.1%–39.8%). These results are the first description of Streptococcus agalactiae-associated otitis. The yeasts isolated showed high levels of susceptibility to all antifungal agents tested; on the con-trary all the isolated bacterial strains were highly resistant to at least four out of ten antimicrobial classes. Both Gram-positive and Gram-negative bacteria showed high resistance to amoxicillin/clavulanate and kanamycin hence they are not recommended as initial empirical therapy for the otitis treatment. Conclusions: This update illustrates an increase in antibiotic resistances providing an insight into the current knowledge of the therapeutic procedures followed on canine otitis externa in Italy. It also emphasizes the importance of considering the results of the microbiological and sensitivity tests to decide on an appropriate antibiotic therapy.

    Full Text Available Uterine infections are one of the major reproductive complications during postpartum. The antibiotics and antiseptic agents used in the treatment of postpartum infections have residues in food, induce bacterial resistance, increase the financial costs and cause failure in defense mechanism of host. On the other hand, nowadays the administration of probiotics is considered as an alternative method for the prevention and treatment of infections. Therefore, preventive treatment with probiotic product could decrease the usage of antibiotic and bring advantages in dairy farm systems. The objective of this study was screening of the antagonistic properties of isolated vaginal Lactic Acid Bacteria (LAB against the most prevalent bacteria in uterine infections in order to investigate their probiotic potentials as an alternative approach for prevention of uterine infections. LAB were isolated from sampling of cranial part of vagina during estrus phase and luteal phase of Holstein dairy cattle and pathogens bacteria were isolated from merits and endometritis specimens which referred to our veterinary laboratory. The antagonistic activity of isolated LAB against uterine pathogens was tested by Agar spot test. Antibiotic susceptibilities of pathogenic strains to commonly used antibiotics were investigated by using disc diffusion method. Inhibition zones around both the probiotic spots and the antibiotic discs were classified to weak, moderate and strong categories and their antagonistic efficacies were compared. Isolated LAB had antagonistic effects against all the pathogenic strains including both gram negative and gram positive, Arcanobacterium pyogenes and Pseudomonas aeroginosa were the most sensitive bacteria (with 12.60 and 14 mm an average inhibition zone, respectively. LAB had the least antagonistic effects on Clostridium perfringens (3.6 mm of an average inhibition zone. Comparing the antagonistic efficacies, the percentages of overall

    Understanding the role of fimbrial subunits during bacterial adherence and the host's immunological response against anchorage proteins is critical for the development of strategies to prevent pathogens from thriving. The objectives of the present study were to locate fimbria-related proteins in the genome of Trueperella pyogenes (CP007519), define their importance for bacterial adherence, and evaluate the association between serum antibodies against fimbrial subunits and uterine health in dairy cows. Using a BLASTp search through the GenBank database, 4 putative clusters for fimbrial assembly were identified in the genome of T. pyogenes, namely FimA, FimC, FimE, and the novel major fimbriae FimJ. The fimbrial proteins FimA, FimC, FimE, and surface-anchored protein (SAP) were cloned into the pET 26b (+) vector, expressed in Escherichia coli BL21, and purified using affinity chromatography. Serum antibodies against FimA, FimC, FimE, and SAP were determined by ELISA on d 260±3 of gestation and at 2±1 and 35±3 d in milk (DIM) to assess the relationship between antigenicity against fimbrial proteins and parameters of uterine health. Antibodies against FimC and FimE were greater both pre- and postpartum in cows from which T. pyogenes was recovered by uterine flushing at 35±3 DIM, whereas T. pyogenes infection was not associated with differences in serum concentrations of FimA and SAP antibodies. Likewise, concentrations of FimC antibodies were consistently greater in cows diagnosed with clinical endometritis at 35±3 DIM compared with healthy counterparts. These results suggest that fimbrial proteins evaluated in the present study, particularly FimC and FimE, are important for maintenance of T. pyogenes in the uterus postpartum and development of uterine diseases in dairy cattle. Additional research is warranted to elucidate the mechanisms by which each fimbrial subunit contributes to the establishment of uterine diseases, evaluate its effect on fertility responses

    The appropriate surgical technique to treat patients with uterine fibroids is still a matter of debate as is the potential risk of incorrect treatment if histological examination detects a uterine sarcoma instead of uterine fibroids. The published epidemiology for uterine sarcoma is set against the incidence of accidental findings during surgery for uterine fibroids. International comments on this topic are discussed and are incorporated into the assessment by the German Society for Gynecology and Obstetrics (DGGG). The ICD-O-3 version of 2003 was used for the anatomical and topographical coding of uterine sarcomas, and the “Operations- und Prozedurenschlüssel” (OPS) 2014, the German standard for process codes and interventions, was used to determine surgical extirpation methods. Categorical qualifiers were defined to analyze the data provided by the Robert Koch Institute (RKI), the German Federal Bureau of Statistics (DESTATIS; Hospital and Causes of Death Statistics), the population-based Cancer Register of Bavaria. A systematic search was done of the MEDLINE database and the Cochrane collaboration, covering the period from 1966 until November 2014. The incidence of uterine sarcoma and uterine fibroids in uterine surgery was compared to the literature and with the different registries. The incidence of uterine sarcoma in 2010, standardized for age, was 1.53 for Bavaria, or 1.30 for every 100 000 women, respectively, averaged for the years 2002–2011, and 1.30 for every 100 000 women in Germany. The mean incidence collated from various surveys was 2.02 for every 100 000 women (0.35–7.02; standard deviation 2.01). The numbers of inpatient surgical procedures such as myoma enucleation, morcellation, hysterectomy or cervical stump removal to treat the indication “uterine myoma” have steadily declined in Germany across all age groups (an absolute decrease of 17 % in 2012 compared to 2007). There has been a shift in the preferred method of surgical

    2015-12-01

    Full Text Available Teeth are most useful tools in victim identification in the living as well as the dead in the field of forensic investigations. Their ability to survive in situations like mass disasters makes them constructive devices. Many authors have measured crowns of teeth in both males and females and found certain variations. Canines, reported to survive in air crash and hurricane disasters, are perhaps the most stable teeth in the oral cavity because of the labiolingual thickness of the crown and the root anchorage in the alveolar process of jaws. Measurement of mesiodistal width of the mandibular canines and inter-canine distance of the mandible provides good evidence of sex identification due to dimorphism. This study was undertaken to evaluate the effectiveness of canine index (CI in the determination of sex.

    Full Text Available Although significant animal suffering caused by preventable diseases is frequently seen in developing countries, reports of this are scarce. This report describes avoidable animal suffering owing to a suspected canine distemper (CD outbreak in unvaccinated dogs owned by low-income families in Mozambique that killed approximately 200 animals. Affected dogs exhibited clinical signs, and gross and microscopic lesions compatible with CD. Immunohistochemical staining confirmed the presence of canine distemper virus (CDV in the kidney of one dog from the cohort. This brief communication again illustrates that large outbreaks of CDV in unvaccinated dogs occur and that large-scale avoidable suffering and threats to the health of dogs and wild canines continue. Mass vaccination supported by government and non-government organisations is recommended.Keywords: Canine distemper; dogs; outbreak; animal welfare; Mozambique

  6. Emerging perspectives on hereditary glomerulopathies in canines

    2015-04-01

    Full Text Available Meryl P LittmanDepartment of Clinical Studies – Philadelphia, University of Pennsylvania School of Veterinary Medicine, Philadelphia, PA, USAAbstract: Familial glomerulopathies have been described in more than two dozen dog breeds. These canine spontaneous cases of glomerular disease are good models for their human counterparts. The dogs present clinically with protein-losing nephropathy and variable signs of hypertension, thromboembolic events, edema/effusions/nephrotic syndrome, or eventually with signs of renal disease such as anorexia, vomiting, weight loss, and/or polyuria/polydipsia. Laboratory changes include proteinuria, hypoalbuminemia, hypercholesterolemia, and eventually azotemia, hyperphosphatemia, anemia, and isosthenuria. Renal biopsies examined with transmission electron microscopy, immunofluorescence, and thin section light microscopy may show ultrastructural glomerular basement membrane abnormalities, glomerulosclerosis, amyloidosis, non-amyloid fibrillary deposition, or breed-associated predispositions for immune-complex glomerulonephritis. Genome-wide association studies and fine sequencing of candidate genes have led to the discovery of variant alleles associated with disease in some breeds; eg, 1 glomerular basement membrane ultrastructural abnormalities due to defective collagen type IV, caused by different premature stop codons in each of four breeds; ie, in COL4A5 in Samoyeds and Navasota mix breed dogs (X-linked, and in COL4A4 in English Cocker Spaniels and English Springer Spaniels (autosomal recessive; and 2 glomerulosclerosis-related podocytopathy with slit diaphragm protein anomalies of both nephrin and Neph3/filtrin due to non-synonymous single nucleotide polymorphisms in conserved regions of their encoding genes, NPHS1 and KIRREL2, in Soft Coated Wheaten Terriers and Airedale Terriers, with a complex mode of inheritance. Age at onset and progression to end-stage renal disease vary depending on the model. Genetic

    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.

  8. Uterine arterial embolization for the treatment of adenomyosis: an analysis of therapeutic results in 80 cases

    International Nuclear Information System (INIS)

    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)

    2013-09-01

    Nutraceuticals, or nutritional supplements, have been promoted for the ancillary treatment of liver disease in dogs. However, minimal information is available in the scientific literature about commonly used nutraceuticals, such as S-adenosylmethionine, silymarin, and vitamin E. No strong clinical evidence exists regarding the efficacy of these compounds as hepatoprotectants in canine liver disease. Until this evidence exists, individual veterinarians must assume responsibility for their decision to use nutritional supplements in their canine patients with liver disease. PMID:23890245

    Full Text Available The diagnosis of intrauterine conditions that may cause infertility is generally made by hysterosalpingography (HSG. Herein, we are presenting seven hysterosalpingo¬graphically-proven patients of Developmental Uterine Cavity Defects. We believed that some of developmental defects of these uterine cavity have not been addressed in preceding medical texts. Accurate diagnosis and reports of such cases are important not only for the benefit of treatment, but also to reflect the true incidence of these anomalies and to consolidate embryologic concept."nThe presented anomalies included "flying bird" uterus, "wine-glass-shaped" uterus, "buffalo head" uterus, "heart-shaped" uterus, "phantom-shaped" uterus, "candle light" uterus, and "jackal-shaped" uterus."nThe presented cases belonged to many years before, thus they were not evaluated by recently-developed advanced diagnostic modalities.

  3. Laparoscopic Ultrasound-Guided Radiofrequency Ablation of Uterine Fibroids

    International Nuclear Information System (INIS)

    Four patients with symptomatic uterine fibroids measuring less than 6 cm underwent laparoscopic ultrasound-guided radiofrequency ablation (RFA) using multiprobe-array electrodes. Follow-up of the treated fibroids was performed with gadolinium-enhanced magnetic resonance imaging (MRI) and patients' symptoms were assessed by telephone interviews. The procedure was initially technically successful in 3 of the 4 patients and MRI studies at 1 month demonstrated complete fibroid ablation. Symptom improvement, including a decrease in menstrual bleeding and pain, was achieved in 2 patients at 3 months. At 7 months, 1 of these 2 patients experienced symptom worsening which correlated with recurrent fibroid on MRI. The third, initially technically successfully treated patient did not experience any symptom relief after the procedure and was ultimately diagnosed with adenomyosis. Our preliminary results suggest that RFA is a technically feasible treatment for symptomatic uterine fibroids in appropriately selected patients

    Full Text Available The aim of the study was to find out the relationship between the progression of endometrosis and the appearance of the structural microscopic changes in mares’ ovaries. The investigation was performed on slaughtered mares of various age and breed. Four groups each received a portion of the specimens, and designation to group was according to the stage of endometrosis determined on the basis of Kenney’s classification. Uterine and ovarian sections were stained with haematoxylin and eosin. The results of the microscopic evaluation were compared between mares classified into specific Kenney’s categories. It was shown that an increase in ovarian follicular cysts was related to mares’ ages and correlated with significant progression of the endometrosis. These observations suggest that the same aetiological factors may take part both in triggering disorders of ovarian oo/folliculogenesis and in spurring uterine endometrosis. Further more detailed methods of investigation are needed to elucidate the mechanisms of both disease processes.

    2009-01-31

    BACKGROUND: It is uncommon to encounter a breast metastasis from an extramammary malignancy and even rarer from a uterine leiomyosarcoma. AIMS: We describe the third case report in the medical literature of a breast metastasis from a uterine leiomyosarcoma. METHODS: We report the management of a 56-year-old patient who presented with a breast lump 3 years after hysterectomy for a fibroid uterus. We conducted a literature review of breast leiomyosarcomas. RESULTS: The excision of the breast mass revealed a low-grade leiomyosarcoma. Radiographic examinations demonstrated metastases to the lung, liver, pelvis and bone. Retrospective pathology review of her uterus identified a small focus of leiomyosarcoma. She received chemotherapy and palliative radiotherapy but passed away within few months. CONCLUSION: Metastasis to the breast from a non-breast primary is generally a sign of disseminated disease and; thus, a poor prognostic indicator.

In this case, the management of a 75-year-old female patient who presented at the outpatient clinic with a history of anuresis and diagnosed with total uterine prolapse, bilateral hydronephrosis, urinary infection and acute renal failure is presented. The renal failure clinical picture regressed with appropriate treatment. However, the patient refused surgery and chose to have a pessary implemented. Four months after dismissal, she was readmitted to the hospital with recurrent renal failure that required dialysis treatment. The patient did not respond to therapy and was placed on a chronic dialysis program with a diagnosis of end-stage renal disease due to posterenal causes.

    Intensive media and policy attention has been focused on the ongoing controversy surrounding uterine morcellation in gynecologic surgery. What has been missing from this impassioned discourse is an objective analysis of the ethical implications of uterine power morcellation in gynecologic surgery. This article discusses competing ethical duties of physicians, industry, the U.S. Food and Drug Administration, and the media to develop a more robust and nuanced understanding of informed consent for the use of morcellation in benign gynecologic surgery. Ultimately, as physicians, we must remain steadfast in our dedication to the use of evolving technologies to better patient health in a safe and ethical manner that is well-studied, informed, and implemented with appropriate training and precautions.

    Uterine natural killer (uNK) cells, sharing many characters with peripheral blood natural killer (pNK) cells, are a major uterine lymphocyte population at early gestational stages during normal pregnancy in placental mammals.The functions of uNK cells include cytokine production and cytotoxcity that are regulated by signals through activating and inhibitory receptors. UNK cells differ from pNK cells however and contribute to the structural changes that accompany the differentiation of the maternal-fetal interface. Immunological mechanisms must provide a balanced environment for uNK cell proliferation, differentiation and activation through intricate signaling pathways. An improved knowledge of mechanisms regulating uNK cells development and the cytokine network at the maternal-fetal interface of mice and humans might be useful to harness the power of these cells for maintenance of pregnancy.

    Background: Previous literature demonstrated that the T2 value of the uterine junctional zone was lower than that of peripheral myometrium by using BOLD MR imaging. We expect T2 mapping image may add more information to T2-weighted images of the uterine myometrium. Purpose: To evaluate whether T2 mapping software would reproduce the result of previous report, and to apply the software to benign uterine diseases. Material and Methods: Five healthy volunteers and 19 patients clinically suspected of having benign pelvic disease were imaged using a 1.5T MR system. All women were of reproductive age, and all provided informed consent. Sagittal T2 images using a multishot EPI sequence were obtained. T2 values were calculated and color T2 maps reconstructed using a T2 fitting tool. Results: The uterine zones could be identified in all 24 examinations on the T2 maps. In addition, a thin '4th zone' was seen between the endometrium and the JZ (junctional zone) in 19 of 24 examinations. The T2 value of JZ was significantly lower than that of peripheral myometrium (PM), (P < 0.001). No significant difference in the T2 value of the JZ or of PM was noted between normal uterus and uterus with leiomyomas and/or adenomyosis. Conclusion: A quantitative T2 map can easily be obtained using the PRIDE software T2 fitting tool, and the software reproduces the result from previous report. T2 value of the junctional zone was lower than that of peripheral myometrium regardless of having benign myometrial diseases.

  20. Vectorial secretion of proteoglycans by polarized rat uterine epithelial cells

    OpenAIRE

    1988-01-01

    We have studied proteoglycan secretion using a recently developed system for the preparing of polarized primary cultures of rat uterine epithelial cells. To mimic their native environment better and provide a system for discriminating apical from basolateral compartments, we cultured cells on semipermeable supports impregnated with biomatrix. Keratan sulfate proteoglycans (KSPG) as well as heparan sulfate- containing molecules (HS[PG]) were the major sulfated products synthesized and secreted...

    Fifteen years has passed since the NCI announced the clinical importance of concurrent chemoradiotherapy (CCRT) in radiotherapy for patients with locoregionally advanced uterine cervical cancer. Numerous clinical trials have been performed to further improve the outcomes of CCRT. In addition to investigations of chemotherapeutic regimens and schedules, adaptation of novel radiotherapy methods such as image-guided brachytherapy (IGBT) and intensity-modulated radiotherapy (IMRT) is encouraged in CCRT for cervical cancer.

    Endometrial adenocarcinoma in the uterine corpus is a malignant cancer that occurs in menopausal women and aged rodents. Because of the similarities in pathogenesis and morphology of endometrial adenocarcinoma in rodents and humans, prediction of the modes of action (MOA) in uterine carcinogenesis is important for extrapolation of rodent data to humans. Three MOAs have been accepted as major pathways for uterine carcinogenesis in rodents: 1) estrogenic activity, 2) increased serum 17beta-estr...

    2008-08-01

    Full Text Available Abstract Canine vector-borne diseases (CVBDs are highly prevalent in Brazil and represent a challenge to veterinarians and public health workers, since some diseases are of great zoonotic potential. Dogs are affected by many protozoa (e.g., Babesia vogeli, Leishmania infantum, and Trypanosoma cruzi, bacteria (e.g., Anaplasma platys and Ehrlichia canis, and helminths (e.g., Dirofilaria immitis and Dipylidium caninum that are transmitted by a diverse range of arthropod vectors, including ticks, fleas, lice, triatomines, mosquitoes, tabanids, and phlebotomine sand flies. This article focuses on several aspects (etiology, transmission, distribution, prevalence, risk factors, diagnosis, control, prevention, and public health significance of CVBDs in Brazil and discusses research gaps to be addressed in future studies.

    The Ethiopian wolf (Canis simensis) is the world's rarest canid; ≈500 wolves remain. The largest population is found within the Bale Mountains National Park (BMNP) in southeastern Ethiopia, where conservation efforts have demonstrated the negative effect of rabies virus on wolf populations. We describe previously unreported infections with canine distemper virus (CDV) among these wolves during 2005-2006 and 2010. Death rates ranged from 43% to 68% in affected subpopulations and were higher for subadult than adult wolves (83%-87% vs. 34%-39%). The 2010 CDV outbreak started 20 months after a rabies outbreak, before the population had fully recovered, and led to the eradication of several focal packs in BMNP's Web Valley. The combined effect of rabies and CDV increases the chance of pack extinction, exacerbating the typically slow recovery of wolf populations, and represents a key extinction threat to populations of this highly endangered carnivore.

    Highly virulent pantropic canine coronavirus (CCoV) strains belonging to subtype IIa were recently identified in dogs. To assess the distribution of such strains in Europe, tissue samples were collected from 354 dogs that had died after displaying systemic disease in France (n = 92), Hungary (n = 75), Italy (n = 69), Greece (n = 87), The Netherlands (n = 27), Belgium (n = 4), and Bulgaria (n = 1). A total of 124 animals tested positive for CCoV, with 33 of them displaying the virus in extraintestinal tissues. Twenty-four CCoV strains (19.35% of the CCoV-positive dogs) detected in internal organs were characterized as subtype IIa and consequently assumed to be pantropic CCoVs. Sequence and phylogenetic analyses of the 5' end of the spike protein gene showed that pantropic CCoV strains are closely related to each other, with the exception of two divergent French viruses that clustered with enteric strains.

    2000-01-01

    The objective of this study was to develop and describe an experimental canine model of multiple acquired portosystemic shunts (PSS) similar in nature to spontaneously occurring PSS. Sixteen dogs were used and were divided into a control (n = 6) and a diseased group (n = 10). Dogs of the diseased group were administered dimethylnitrosamine (2 mg/kg of body weight, po) twice weekly, and clinicopathologic, ultrasonographic, and hepatic scintigraphic findings were recorded during the development of hepatic disease and PSS. Surgery was then performed to permit visual verification of multiple shunts, catheter placement for portography examination, and biopsy of the liver. All diseased dogs developed severe hepatic disease and multiple PSS as documented visually at surgery and on portography. Based on this study, dimethylnitrosamine-induced portosystemic shunting appears to be an appropriate model for spontaneously occurring multiple PSS secondary to portal hypertension. PMID:10741951

  10. Canine model of contrast medium induced fibrillation

    International Nuclear Information System (INIS)

    The injection of radiocontrast media into coronary arteries will produce a low incidence of ventricular fibrillation. This study establishes the injection duration (or contact time) required to produce fibrillation during right coronary angiography in dogs using a 370 mg I/ml, meglumine/sodium diatrizoate formulation (Renografin 76, Squibb). The mean contact time required to induce fibrillation was 18.8+-5.8 seconds for 66 injections in 47 dogs. Prolonged ischemia of greater than 170 s did not produce either fibrillation or arrhythmias, therefore fibrillation is caused by properties of the media. The contact time was not significantly influenced by test injections and was not significantly different in repeated experiments. The canine contact time model of contrast media induced ventricular fibrillation is reproducible and will facilitate the study of risk factors that increase the possibility of fibrillation. (orig.)

    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.

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

    Purpose: To evaluate the role of uterine artery embolisation (UAE) in the treatment of adenomyosis. Materials and methods: 27 women with symptomatic adenomyosis diagnosed on magnetic resonance imaging (MRI) underwent UAE between 1998 and 2004. Clinical evaluation using a standardised questionnaire was made at regular intervals after embolisation to assess patient outcome. Results: The diagnosis of adenomyosis was confirmed histologically by transvaginal biopsy in 5 women. There were 14 women with associated uterine fibroids. Diffuse adenomyosis was identified in 18 women. A focal adenomyoma was present in another 8 women. In 1 patient adenomyosis was not classified. All patients except one underwent bilateral uterine artery embolisation. There was an initial favourable clinical response, with improvement of menorrhagia in 79% (13/16) of patients at 12 months. Follow-up data was available on a total of 14 patients at 2 and 3 years after embolisation. 45.5% (5/11) reported a deterioration in menorrhagia symptoms at 2 years. Conclusion: UAE for symptomatic adenomyosis is effective in the short-term but there is a high rate of recurrence of clinical symptoms 2 year following treatment.

    Uterine myoma and adenomyosis are the two most likely diagnoses in women with hypermenorrhea, dysmenorrhea, and an enlarged uterus, but it is often not possible to make a distinction between them preoperatively. But their treatments can differ : myoma can be treated through myomectomy whereas adenomyosis require hysterectomy. In order to establish the characteristic and differential findings of myoma and adenomyosis sonographically, sonographic findings of 125 cases of pathologically proven myoma and adenomyosis were reviewed retrospectively. Histologic diagnosis were myoma in 94 patients and adenomyosis in 31 patients. The results were as follows : 1. The common sonographic findings of uterine myoma were globular enlargement or bulging contour of uterus 77.8%, loss of central endometrial echoes 66.0%, and homogeneous decreased internal echoes 35.1% or heterogeneous internal echoes 44.7%. 2. The common sonographic findings of adenomyosis were diffuse enlargement without contour change 80.6%, homogeneous hypoechoic or isoechoic internal textures 96.8%, preserved central endometrial echoes 80.6%, and thickening of posterior uterine wall 64.5%. 3. Adenomyosis was highly suggested if the uterus showed diffuse enlargement without contour change or visible nodule, homogeneous hypoechoic textures, and especially thickened posterior wall with anteriorly displaced central endometrial echoes. 4. Adenomyosis could be excluded if the patient was under 30 or above 50 years old, and especially had no previous obstetric history.

  17. Radiation-induced secondary cancer in patients with uterine carcinoma

    International Nuclear Information System (INIS)

    In an effort to identify radiation-induced secondary cancer (RSC), data from 19,384 patients, which were treated for uterine carcinoma at seven institutions in Japan between 1960 and 1978, were statistically analyzed using a computer system. Treatment modalities included surgery alone (n = 6,655), radiation therapy and surgery (n = 4,310), and radiation therapy alone (n = 8,419). According to the criteria of Sakai et al., RSC was identified in 43 (0.3 %) of 12,729 patients receiving irradiation, including rectal cancer (14), leukemia (8), uterine corpus cancer (6), urinary bladder cancer (4), osteosarcoma or uterine sarcoma (3), sigmoid colon cancer or malignant fibrous histiocytoma (2), and ovarian cancer (one). When the risk of RSC for the rectum, the urinary bladder, and leukemia was analyzed using a person-years method, there was no statistically significant difference between the irradiated and non-irradiated patients. Therefore, three institutions were selected for further analysis with 2,686 patients (13,588 person-years), taking the effort and accuracy for follow-up of patients into account. The analysis showed statistically significant increase in RSC for the rectum and leukemia. It can thus be concluded that the accuracy for follow-up of patients is the most important factor in evaluating the incidence of RSC. (Namekawa, K.)

    AIM: To present the findings of uterine artery embolization (UAE) in the management of obstetric haemorrhage. MATERIALS AND METHODS: From October 1999 to February 2003, 10 women with postpartum haemorrhage (n=7) and post-abortion haemorrhage with placenta accreta (n=3), were referred to our department for pelvic angiography and possible arterial embolization. RESULTS: Angiography revealed engorged and tortuous uterine arteries in all patients; and contrast medium extravasation in three patients. Eight patients (three with and five without detectable active bleeding) then underwent bilateral UAE. Medium-sized (250-355 {mu}m) polyvinyl alcohol particles were injected via a coaxial catheter into the uterine arteries, followed by gelatin sponge pieces via a 4 F Cobra catheter. Microcoil devascularization was also performed in the two patients with visible, active bleeding. The vaginal bleeding resolved in all patients, without any ischaemic complications. At follow-up, all patients who underwent UAE had normal menstruation; three of them subsequently gave birth to full-term healthy babies. CONCLUSION: Selective UAE by the coaxial method is safe and effective to control obstetric haemorrhage, with the potential to preserve fertility.

    International Nuclear Information System (INIS)

    Objective: To study the feasibility, safety, and efficacy of the treatment for tubal pregnancy by interventional technique of transuterine arterial catheterization perfusion and embolization. Methods: Using modified Seldinger technique, 42 cases of tubal pregnancy received super-selective angiography of uterine artery, followed by perfusion of 50-100 mg methotrexate (MTX) through the catheter and embolization of uterine artery with gelatin sponge. Before and after the procedure, changes of clinical symptoms, physical signs, value of β-hCG and size of pregnancy cyst of patients were studied. Concentrations of MTX in peripheral blood were studied at 0.5, 6, 12, 24, 36, 48 hours after the procedure. Results: 38 out of 42 cases were cured with successful rate of 90.5%(38/42). The average time of β-hCG decreasing to normal was 8.26 ± 2.04 days. The concentration of MTX in peripheral blood with 50 mg or 75 mg dosage could not be detected at 36 hours after the procedure but could be detected as 0.01 μmol/L at 48 hours after the procedure with a dosage of 100 mg. Conclusions: It is simple, safe and efficient in performing trans-uterine artery chemo-embolization for therapy of fallopian tubal pregnancy, especially for those who complicated with manipules bleeding and also as the first choice for prevention of high risk massive hemorrhage.

    Arthrogryposis multiplex congenital is a rare condition defined as contractures in multiple joints at birth due to disorders starting in fetal life. Its etiology is associated with many different conditions and in many instances remains unknown. The final common pathway to all of them is decreased fetal movement (fetal akinesia) due to an abnormal intrauterine environment. Causes of decreased fetal movements may be neuropathic abnormalities, abnormalities of connective tissue or muscle, intrauterine vascular compromise, maternal diseases, and space limitations within the uterus. When the cause of arthrogryposis is space limitations in uterus, the most common etiology is oligohydramnios. The same can result from intrauterine tumours as fibroids, although to our knowledge there are only two papers reporting cases of fetal deformities related to uterine leiomyomas. We describe a well-documented exceptional case of arthrogryposis associated with the presence of a large uterine fibroid. It could illustrate the importance of a careful and appropriate assessment of uterine fibroids before and in the course of a pregnancy considering that they can cause both serious maternal and fetal complications.

    Proliferating cells exhibit accelerated rates of substrate utilization, favoring glucose over fatty acids (FA's) oxidation. Protein-mediated transport is thought to play a predominant role in facilitating either glucose or FA routing into the cells. In the present study, we examined the expression of glucose transporters (GLUT-1, GLUT-4) and fatty acids transporters (FAT/CD36, FATP-1, FATP-4) at transcript and protein levels as well as cytosolic fatty acid binding proteins (H-FABP, ACBP) in human fibroids (n=74, size up to 3cm diameter) and compared with pair-matched healthy myometrium. Additionally lipid content (diacylglycerols, triacylglycerols and ceramide) was estimated by gas liquid chromatography (GLC). Uterine fibroids displayed decreased expression of both FAT/CD36 and FATP-1 proteins along with lower diacylglycerol (DAG) and triacylglycerol (TAG) content as compared to healthy pair-matched myometrium. The expression of glucose transport proteins (GLUT-4 and GLUT-1) remained relatively constant, although the higher expression of GLUT-1 in uterine fibroids did not reach the minimum significance threshold (p=0.056). However, no change in either cytochrome c oxidase (COX IV) or hydroxyacyl-CoA dehydrogenase (HADHSC) was observed and these data confirm a possible metabolic shift favoring glucose utilization over fatty acid oxidation in human uterine fibroids.

    The purpose of this retrospective study was to evaluate the efficacy and feasibility of short-course hypofractionated radiotherapy (RT) for the palliation of uterine cervical cancer. Seventeen patients with cancer of the uterine cervix, who underwent palliative hypofractionated 3-dimensional conformal radiotherapy between January 2002 and June 2012, were retrospectively analyzed. RT was delivered to symptomatic lesions (both the primary mass and/or metastatic regional lymph nodes). The total dose was 20 to 25 Gy (median, 25 Gy) in 5 Gy daily fractions. The median follow-up duration was 12.2 months (range, 4 to 24 months). The median survival time was 7.8 months (range, 4 to 24 months). Vaginal bleeding was the most common presenting symptom followed by pelvic pain (9 patients). The overall response rates were 93.8% and 66.7% for vaginal bleeding control and pelvic pain, respectively. Nine patients did not have any acute side effects and 7 patients showed minor gastrointestinal toxicity. Only 1 patient had grade 3 diarrhea 1 week after completion of treatment, which was successfully treated conservatively. Late complications occurred in 4 patients; however, none of these were of grade 3 or higher severity. Short-course hypofractionated RT was effective and well tolerated as palliative treatment for uterine cervical cancer.

Design Two sets of dogs (6 breeds) were genotyped with dense SNPs covering the entire canine genome. The first set contained 359 dogs upon which a predictive formula for genomic breeding value (GBV) was derived by using their estimated breeding value (EBV) of the Norberg angle (a measure of CHD) and their genotypes. To investigate how well the formula would work for an individual dog with genotype only (without using EBV or phenotype), a cross validation was performed by masking the EBV of one dog at a time. The genomic data and the EBV of the remaining dogs were used to predict the GBV for the single dog that was left out. The second set of dogs included 38 new Labrador retriever dogs, which had no pedigree relationship to the dogs in the first set. Results The cross validation showed a strong correlation (r>0.7) between the EBV and the GBV. The independent validation showed a strong correlation (r=0.5) between GBV for the Norberg angle and the observed Norberg angle (no EBV was available for the new 38 dogs). Sensitivity, specificity, positive, and negative predictive value of the genomic data were all above 70%. Conclusions Prediction of CHD from genomic data is feasible, and can be applied for risk management of CHD and early selection for genetic improvement to reduce the prevalence of CHD in breeding programs. The prediction can be implemented before maturity, at which age current radiographic screening programs are traditionally applied, and as soon as DNA is available. PMID:21215318

  6. Fluorescein angiography of the canine retina

    International Nuclear Information System (INIS)

    The retinal vascular bed was examined in 37 canine eyes by studying 50 retinal fluorangiograms. All angiographic phases could distinctly be visualized by the use of a small intravenous bolus of 10 mg/kg fluorescein. The choroidal phase is characterized by spot-like and lobular filling of the choriocapillaris. By coalescence of the choroidal lobules, this uneven filling progressively disappears in the subsequent phases. The retinal arterial phase is characterized by a hyperfluorescence of the retinal arterioles at the level of the optic disc border. The time interval between the start of the choroidal phase and the retinal arterial phase is very short due to the common origin of the choroidal and retinal arteries from the choroidoretinal arteries. The retinal arterio-venous phase is characterized by a complete filling of the smaller arterioles, capillaries, and venules. During this phase the branching pattern of the retinal blood vessels at the area centralis region can be most easily studied. This also applies to the periarteriolar capillary-free zones and the radial peripapillary capillaries. The retinal early venous phase is characterized by the onset of laminar flow in the larger retinal venules. A homogeneous and complete filling of the larger venules is characteristic for the onset of the late venous phase. During the retinal venous phase the border venule can be observed just posterior to the ora ciliaris retinae. Fluorescein angiography of the canine retinal microvasculature shows that the dog is less suitable as an experimental animal model in ophthalmology, due to the presence of the choroidal tapetum which reflects fluorescent light and thus diminishes the contrast between the retinal blood vessels and the background

    IL-1 and TNF are important proinflammatory cytokines implicated in both antimicrobial host defense and pathogenesis of diseases with an immune-mediated and/or inflammatory component. Respective studies in the dog have been hampered by the unavailability of reagents allowing the specific measurement of canine cytokine proteins and the effect of canine cytokine neutralization by Ab. Starting with recombinant canine (rcan) IL-1beta and rcanTNF, four polyclonal antisera and 22 mAb specific for rcanIL-1beta and rcanTNF were generated. Their usefulness in neutralization assays was determined. Using cytokine-containing supernatants of canine cells in bioassays, polyclonal antisera neutralized either canine IL-1beta or TNF. TNF was also neutralized by three antibodies developed in this study and one commercial mAb. The usefulness of monoclonal and polyclonal Ab in canine cytokine-specific Ab capture ELISA's was assessed. This resulted in the identification of a commercial mAb combination and one pair developed in this study allowing low levels of TNF to be detected by antibody capture ELISA. The detection limit was 141 pg/ml rcanTNF for both combinations. Using rcanIL-1beta as an antigen allowed the detection of lower concentrations of rcanIL-1beta (20 pg/ml, on the average) by a pair of polyclonal antisera than when monoclonals were used. By using such IL-1beta-specific and TNF-specific ELISA's, the respective cytokines were detected in supernatants of canine PBMC stimulated with LPS or heat-killed Listeria monocytogenes and interferon-gamma combined. Thus, monoclonal and polyclonal reagents were identified allowing the quantitation of canine IL-1beta and TNF production in vitro, and the neutralization of these cytokines. PMID:15982477

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

    To assess the effects of a single supraphysiological postnatal administration of a progestogen on uterine glands in dogs, 10 females were randomly assigned to a medroxyprogesterone acetate 35 mg (MPA; n = 6) or placebo (n = 4) group within the first 24 h of birth. The safety of the treatment was also evaluated. A transient mild clitoris enlargement appeared in MPA-treated females. Microscopic postpubertal uterine assessment revealed the presence of uterine glands in all cases without significant differences in the area occupied by the glands per µm(2) of endometrium nor in the height of the uterine epithelium.

    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.

    Bone morphogenetic proteins (BMPs) are extracellular, multifunctional growth factors that constitute the largest subset of the transforming growth factor β superfamily. BMP2 is involved in cardiovascular embryogenesis, in addition to a variety of other postnatal functions, such as neovascularization, osteoinduction, tumor signaling, and in the uterus, stromal decidualization at the implantation site. Estrogen receptor signaling is common in smooth muscle tumors of the uterus, and preclinical models suggest significant interactions between BMP2 and estrogen receptor-mediated signaling. The purpose of this study is to define the patterns of BMP2 expression, as assessed by immunohistochemistry, in smooth muscle tumors and other tissues of the uterine corpus, and to establish whether BMP2 expression has any prognostic significance in uterine leiomyosarcomas. BMP2 was positive (cytoplasmic pattern, typically focal) in 24% of leiomyosarcomas and 20.7% of leiomyomata, but was either infrequently expressed or not expressed in all other tissues evaluated, including normal myometrium and endometrium, endometrial stromal tumors, typical adenomyoma, adenomyosis, and serosal endometriosis. The endothelial cells of small, thin-walled vessels were frequently, but not invariably immunoreactive for BMP2. There was no significant difference between BMP2⁺ and BMP⁻ leiomyosarcomas regarding average tumor size, average patient age, microvessel density, and proportions with high tumor grade, advanced stage and frequency of death from disease on follow-up. Two (29%) of 7 BMP2⁺ leiomyosarcomas were estrogen receptor+, compared with 5 (50%) of 10 BMP2⁻ leiomyosarcomas, a statistically insignificant difference (P=0.62). It is concluded that BMP2 is only expressed in a minority of smooth muscle tumors of the uterine corpus, and lacks prognostic significance in leiomyosarcomas. BMP2 is rarely expressed in the other nonendothelial tissues of the human uterine corpus that were

    Full Text Available Abstract Background Unlike other domestic mammals, in which metaphase-II oocytes are ovulated, canine ovulation is characterized by the release of primary oocytes, which may take 12 to up to 36 hours. Further 60 hours are needed for maturation to secondary oocytes which then remain fertile for about 48 hours. Oestrus takes 7 to 10 days on average and may start as early as a week before ovulation. This together with the prolonged process of post-ovulatory oocyte maturation requires an according longevity of spermatozoa in the female genital tract in order to provide a population of fertile sperm when oocytes have matured to fertilizability. Therefore the distribution and viability of spermatozoa in the bitch genital tract was examined during post-ovulatory oocyte maturation. Methods Thirteen beagle bitches were inseminated on the day of sonographically verified ovulation with pooled semen of two beagle dogs containing one billion progressively motile spermatozoa. Ovariohysterectomy was performed two days later (group 1, n = 6 and four days later (group 2, n = 7. The oviduct and uterine horn of one side were flushed separately and the flushing’s were checked for the presence of gametes. The oviducts including the utero-tubal junction and the uterine horns, both the flushed and unflushed, were histologically examined for sperm distribution. Results The total number of spermatozoa recovered by flushing was low and evaluation of viability was limited. Prophase-I oocytes were collected from oviduct flushing in group 1, whereas unfertilized metaphase-II oocytes were detected in group 2. From day 2 to day 4 after ovulation a significant decrease in the percentage of glands containing sperm (P Conclusions Oocyte maturation to metaphase-II stage is accompanied by a continuous sperm detachment and elimination in the uterine horns. Entrance of spermatozoa into the caudal oviduct seems to be steadily controlled by the utero-tubal junction thus

  17. Mid-term Clinical Results and Patient Satisfaction After Uterine Artery Embolization in Women with Symptomatic Uterine Fibroids

    International Nuclear Information System (INIS)

    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

    Full Text Available Cystic endometrial hyperplasia (CEH, mucometra, and pyometra are common uterine diseases in intact dogs, with pyometra being a life threatening disease. This study aimed to determine the gene expression profile of these lesions and potential biomarkers for closed-cervix pyometra, the most severe condition. Total RNA was extracted from 69 fresh endometrium samples collected from 21 healthy female dogs during diestrus, 16 CEH, 15 mucometra and 17 pyometra (eight open and nine closed-cervixes. Global gene expression was detected using the Affymetrix Canine Gene 1.0 ST Array. Unsupervised analysis revealed two clusters, one mainly composed of diestrus and CEH samples and the other by 12/15 mucometra and all pyometra samples. When comparing pyometra with other groups, 189 differentially expressed genes were detected. SLPI, PTGS2/COX2, MMP1, S100A8, S100A9 and IL8 were among the top up-regulated genes detected in pyometra, further confirmed by external expression data. Notably, a particular molecular profile in pyometra from animals previously treated with exogenous progesterone compounds was observed in comparison with pyometra from untreated dogs as well as with other groups irrespective of exogenous hormone treatment status. In addition to S100A8 and S100A9 genes, overexpression of the inflammatory cytokines IL1B, TNF and IL6 as well as LTF were detected in the pyometra from treated animals. Interestingly, closed pyometra was more frequently detected in treated dogs (64% versus 33%, with IL1B, TNF, LBP and CXCL10 among the most relevant overexpressed genes. This molecular signature associated with potential biomarkers and therapeutic targets, such as CXCL10 and COX2, should guide future clinical studies. Based on the gene expression profile we suggested that pyometra from progesterone treated dogs is a distinct molecular entity.

  20. Physiological Uptake of 18F-Fluorodeoxyglucose in Uterine Endometrium and Myometrium: Correlation with Uterine Motility Evaluated by Cine Magnetic Resonance Imaging

    International Nuclear Information System (INIS)

    Background: Accumulation of 18F-fluorodeoxyglucose (18F-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 18F-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
