    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 An 11-year-old Labrador Retriever bitch with a history of intermittent, sanguineous vaginal discharge of a six-month duration was presented. During exploratory laparotomy, two well-delineated, intramural masses were identified bilaterally in the uterine horns. Histopathologic examination of the mass on the left horn showed that it was a typical leiomyoma. However, the second mass appeared with an unusual coexistence of histological lesions, involving epithelial tissue foci, mild focal adenomyosis, and cystic endometrial hyperplasia. Interestingly, such combination was never encountered before in dogs. Although uterine leiomyoma is quite usual in the reproductive system of female dogs, this case resembled relevant cases of human uterine adenomyomas in morphology, and thus it was offered a similar tentative diagnosis.

    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

    Two antibacterial shampoos for the treatment of canine bacterial overgrowth syndrome (BOGS) were compared in a prospective controlled clinical trial. Forty dogs with clinical signs (pruritus, erythema and excoriations without pustules and/or collarettes) and cytological findings compatible with bacterial overgrowth were treated twice weekly with 3 per cent chlorhexidine shampoo (3 per cent CHX) or 2.5 per cent benzoyl peroxide shampoo (2.5 per cent BPO) and evaluated every two weeks for up to six weeks until cytological cure. Pruritus, erythema, greasy seborrhoea, malodour, excoriations, secondary hair loss, lichenification, hyperpigmentation and lesion extent were each scored on a 0 to 3 severity scale and combined to calculate an aggregate score. Among the 34 dogs with good compliance to treatment, reduction of cocci counts of at least 90 per cent was recorded in 11 of 18 dogs after 3 per cent CHX and nine of 16 dogs after 2.5 per cent BPO, with no significant difference between the two products (P=0.98). Lesion score was significantly reduced in both groups (63.48 (34.45)) per cent with 3 per cent CHX v 54.45 (33.61) per cent with 2.5 per cent BPO, P=0.36) and time to cytological cure was not significantly different between groups (P=0.13), at the end of the treatment. In the present study, 3 per cent CHX and 2.5 per cent BPO were similarly effective in the treatment of canine BOGS.

    Full Text Available Abstract Background Bacterial vaginosis (BV, an alteration of vaginal flora involving a decrease in Lactobacilli and predominance of anaerobic bacteria, is among the most common cause of vaginal complaints for women of childbearing age. It is well known that BV has an influence in acquisition of certain genital infections. However, association between BV and cervical human papillomavirus (HPV infection has been inconsistent among studies. The objective of this meta-analysis of published studies is to clarify and summarize published literature on the extent to which BV is associated with cervical HPV infection. Methods Medline and Web of Science were systematically searched for eligible publications until December 2009. Articles were selected based on inclusion and exclusion criteria. After testing heterogeneity of studies, meta-analysis was performed using random effect model. Results Twelve eligible studies were selected to review the association between BV and HPV, including a total of 6,372 women. The pooled prevalence of BV was 32%. The overall estimated odds ratio (OR showed a positive association between BV and cervical HPV infection (OR, 1.43; 95% confidence interval, 1.11-1.84. Conclusion This meta-analysis of available literature resulted in a positive association between BV and uterine cervical HPV infection.

    Dog cloning offers a substantial potential because of the advancements in assisted reproductive technology and development of the human disease model in line with the transgenic technique. However, little is known about the development of the canine cloned embryo during the preimplantation period. The aim of this study was to investigate the most efficient method and time for collecting cloned canine preimplantation embryos and to ascertain the developmental timeline of cloned canine embryos. Two hundred cloned embryos were created and transferred into 11 surrogates. The preimplantation stage cloned embryos were then collected on Days 7, 8, and 9 using an ovariohysterectomy or the Foley balloon catheter method. The recovery rate of reconstructed embryos was 63.6% and 60.6% for the ovariohysterectomy and Foley balloon catheter methods, respectively. Although significant differences were observed in the early developmental stages (one-cell and 16-cell stages), no significant difference was observed in the blastocyst stage. Significantly higher blastocyst rate was observed when the embryos were collected on Day 8 (11.4%) than on Day 7 (0.0%; P cloned embryos can develop to blastocysts by Day 8, and full-term pregnancy can be achieved after embryo transfer in canine.

    We investigated the relationship between the persistence of uterine bacterial infections with cytologically determined endometritis and ovarian function in 65 postpartum Holstein cows. Vaginal mucus discharges were collected, and endometrial smear samples (n = 130) were collected for cytological and bacteriological examinations from the cows at weeks 5 and 7 postpartum (pp). 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). A positive correlation (P < 0.001) was noted between the severity of cytologically determined endometritis, purulent vaginal discharge and the persistence of infection. Cows with persistent infections had a significantly (P < 0.01) prolonged luteal phase compared with cows without infection. In conclusion, the prevalence of cytologically determined endometritis and prolonged luteal phase were significantly increased in cows with persistent infections. PMID:25482111

    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 is a bacterial infection of the uterus that is common in dogs and is potentially life-threatening if delayed in diagnosis and/or treatment. Thymidine kinase 1 (TK1) is a cytosolic enzyme involved in DNA precursor synthesis, and it is also present in serum from patients with malignant diseases. TK1 has been used as a cell proliferation biomarker for many years in human medicine and recently in dogs. However, little is known regarding serum TK1 levels in individuals with bacterial infection. The objective of this study was to determine the activity of serum TK1 in dogs with pyometra and compare it with hematologic and biochemical parameters, e.g., acute phase proteins and inflammatory mediators such as C-reactive protein and Prostaglandin F(2α). Serum and plasma TK1 activity of 40 healthy female dogs and 54 dogs with pyometra were analyzed using an optimized [(3)H]-thymidine phosphorylation assay. TK1 activities in serum or plasma were significantly higher in dogs with pyometra as compared with healthy female dogs (mean ± SD: 4.0 ± 7.3 pmol/min/mL in the pyometra group and 1.07 ± 0.34 pmol/min/mL in healthy control group). However, there was no difference in TK1 activity between systemic inflammatory response syndrome (SIRS) positive (n = 38) and SIRS negative (n = 16) pyometra cases. Furthermore, the plasma TK1 activity decreased in six and increased in one pyometra patients (n = 10), 24 h after ovariohysterectomy. No significant correlations (P > 0.05) were found between TK1 activity and hematological or other biochemical parameters. In conclusion, the TK1 activity was significantly elevated in dogs with pyometra. Further studies are needed to evaluate the mechanism and role of serum TK1 activity in bacterial infections and its possible diagnostic or prognostic value. PMID:23102844

    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 dogs might suggest genetic variations or epigenetic differences in FimH receptor expression by the endometrium, unrelated to the stage of the oestrous cycle.

    The pathogenesis of canine pyometra is still unclear, but bacterial infection of the endometrium, mediated by bacterial lectins, is suspected to induce pyometra. The aim of this study was to investigate sugar expression in the mucosae of the uterus and vagina of healthy dogs with normal oestrous cycles and in dogs with pyometra, using a panel of lectins to investigate the pathogenesis of pyometra. In dogs with pyometra, the uterine and vaginal mucosae were positive for lectins that selectively bind to glucose or mannose, especially during days 7-10 and 30-40 of dioestrus. These results suggest that temporal changes in sugar expression in the uterus and vagina present an opportunity for pathogens to infect the endometrium, causing pyometra. PMID:22990121

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

    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

    Full Text Available Uterine fibroids are commonly asymptomatic. They often cause pelvic pain, abnormal and increased vaginal bleeding, etc. Traditional treatment of symptomatic uterine fibroids was trans-abdominal hysterectomy. Nowadays, uterine artery embolization (UAE, also called uterine fibroid embolization, is considered as a safe and highly-effective nonsurgical treatment for women with symptomatic uterine fibroid tumors. Advantages of UAE over conventional hormonal suppression and surgical procedures include avoidance of the side effects of drug therapy and surgery-related physical and psychological trauma. These patients commonly resume their normal activities within a week after the procedure; weeks earlier than that for trans-abdominal hysterectomy. Over the past 30 years, interventional radiologists have done UAE for treatment of emergency uterine bleeding. Since 1995, interventional radiologists have turned their attention to treatment of uterine fibroids with a similar procedure. The first fibroid embolization in Iran was done approximately three years ago. So far, more than 100 cases have been treated by this method and it is going to be quickly accepted as a safe alternate for surgery.

    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

    Uterine papillary serous carcinoma (UPSC) is a histologic variant of endometrial cancer that accounts for only 10% of new cases of uterine cancer but is responsible for 40% of deaths from the disease. UPSC is an aggressive tumor with a predilection for early spread beyond the uterus. Treatment for UPSC typically entails surgery and in most women is followed by multimodality adjuvant therapy. In this review, we describe the epidemiology, natural history, treatment, and outcome of UPSC. PMID:21508697

  8. 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.

    Twenty-three virgin Holstein heifers received uterine inoculations with ureaplasma and were necropsied one to thirteen days later. Three heifers inoculated intracervically were necropsied on days 3, 5 and 11.Granular vulvitis was produced on average by 3.6 days in fourteen of sixteen uterine inoculated heifers monitored for four or more days. Two cervically inoculated heifers monitored for over four days also developed granular vulvitis by the fourth day. At necropsy, ureaplasma was recovered from 94% of uterine horn cultures for the first four days postinoculation and 50% during days 5 to 7. Thereafter all uterine cultures were negative. The percentage of positive ureaplasma recoveries from uterine tube flushings was lower than for uterine horns but remained positive for a longer period. By day 7, three of four uterine tube flushings were still positive. No bacterial pathogens were isolated from the uterine horns or uterine tube flushings. On histopathology 50% of uterine inoculated heifers had endometritis up to six days postinoculation and a slightly higher percentage (58%) had salpingitis. Endometritis was not found in any heifers after day 6. Residual salpingitis was present in one heifer on day 7. Endometritis was present in cervically inoculated heifers necropsied on days 3 and 5 but not on day 11. Salpingitis was not found in any of the three cervically inoculated animals. The study concluded that some strains of ureaplasma are pathogenic for the upper reproductive tract of the cow and should be considered significant when isolated from cases of granular vulvitis, endometritis or salpingitis.

    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

    2013-01-01

    Primary lymphomas of the canine female genital tract are uncommon tumours. A 9-year-old intact female Lhasa Apso dog presenting with a closed pyometra underwent an ovariohysterectomy (OHE), and the hyperplastic uterine horn along with multiple follicular cysts on the right ovary was examined by histological analysis. Severe infiltration of medium-sized lymphocytes with strong positive immunoreactivity for CD79a and numerous anaplastic features was detected in the unilateral uterine horn, and the dog was diagnosed as having extranodal marginal zone B-cell lymphoma (MZBCL). The present case reports an extremely rare occurrence of primary lymphoma involving the uterine horn in a dog and describes histological characteristics of the tumour for definite diagnosis.

  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

    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

  3. 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

  4. 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. 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. In 17 patients (89.5 %), the menstrual cycle returned to normal. All patients experienced pain after the procedure and other complications were vaginal bleeding (26.3 %) and fever (23.8 %). Uterine arterial embolization represents a new approach to the management of uterine leiomyoma-related symptoms. Further investigations and long-term follow-up are, however, enquired

    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

    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.

  8. 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...... to 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.

    2016-07-01

    Abnormal uterine bleeding (AUB) is a common and debilitating condition with high direct and indirect costs. AUB frequently co-exists with fibroids, but the relationship between the two remains incompletely understood and in many women the identification of fibroids may be incidental to a menstrual bleeding complaint. A structured approach for establishing the cause using the Fédération International de Gynécologie et d'Obstétrique (FIGO) PALM-COEIN (Polyp, Adenomyosis, Leiomyoma, Malignancy (and hyperplasia), Coagulopathy, Ovulatory disorders, Endometrial, Iatrogenic and Not otherwise classified) classification system will facilitate accurate diagnosis and inform treatment options. Office hysteroscopy and increasing sophisticated imaging will assist provision of robust evidence for the underlying cause. Increased availability of medical options has expanded the choice for women and many will no longer need to recourse to potentially complicated surgery. Treatment must remain individualised and encompass the impact of pressure symptoms, desire for retention of fertility and contraceptive needs, as well as address the management of AUB in order to achieve improved quality of life.

    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.

    Full Text Available Aim: To analyse the microbial profile of canine persistent wound infections. Materials and Methods: The total wound samples (n=172 taken from both traumatic (140 and post-surgical (32 persistent wounds in canines were processed for routine microbial isolation and identification during a period of 15 months. Results: Staphylococcus intermedius was found to be the predominant isolate from all types of wounds under study. It was followed by Staphylococcus aureus, Pseudomonas aeruginosa, E. coli, Pasteurella spp., Corynaebacterium spp. and Bacillus spp. From different traumatic wounds of dogs, S. intermedius (92/140=65.7% and from surgical wounds, P. aeruginosa (24/32=75% were found to be the predominant isolates recovered whereas the most commonly isolated bacterial genus in both traumatic and surgical wounds of dogs was Staphylococcus spp. Conclusion: Canine wounds are polymicrobial in nature. Hence proper microbial laboratory diagnosis and presence of multiple organisms in a wound are to be taken into consideration for effective treatment of persistent wound infections in dogs.

    Uterine fibroids are the most common tumors in women and their prevalence is higher in patients with infertility. At present, they are classified according to their anatomical location, as no classification system includes additional parameters such as their size or number. There is a general agreement that submucosal fibroids negatively affect fertility, when compared to women without fibroids. Intramural fibroids above a certain size (>4 cm), even without cavity distortion, may also negatively influence fertility. However, the presence of subserosal myomas has little or no effect on fertility. Many possible theories have been proposed to explain how fibroids impair fertility: mechanisms involving alteration of local anatomical location, others involving functional changes of the myometrium and endometrium, and finally endocrine and paracrine molecular mechanisms. Nevertheless, any of the above mentioned mechanisms can cause reduced reproductive potential, thereby leading to impaired gamete transport, reduced ability for embryo implantation, and creation of a hostile environment. The published experience defines the best practice strategy, as not many large, well-designed, and properly powered studies are available. Myomectomy appears to have an effect in fertility improvement in certain cases. Excision of submucosal myomas seems to restore fertility with pregnancy rates after surgery similar to normal controls. Removal of intramural myomas affecting pregnancy outcome seems to be associated with higher pregnancy rates when compared to non-operated controls, although evidence is still nοt sufficient. Treatment of subserosal myomas of reasonable size is not necessary for fertility reasons. The results of endoscopic and open myomectomy are similar; thus, endoscopic treatment is the recommended approach due to its advantages in patient's postoperative course. PMID:26856931

    Full Text Available Leishmaniasis is the third most important vector-borne disease worldwide. Visceral leishmaniasis (VL is a severe and frequently lethal protozoan disease of increasing incidence and severity due to infected human and dog migration, new geographical distribution of the insect due to global-warming, co-infection with immunosuppressive diseases and poverty. The disease is an anthroponosis in India and Central Africa and a canid zoonosis (ZVL in the Americas, the Middle East, Central Asia, China and the Mediterranean. The ZVL epidemic has been controlled by one or more measures including the culling of infected dogs, treatment of human cases and insecticidal treatment of homes and dogs. However, the use of vaccines is considered the most cost-effective control tool for human and canine disease. Since the severity of the disease is related to the generation of T-cell immunosuppression, effective vaccines should be capable of sustaining or enhancing the T-cell immunity. In this review we summarize the clinical and parasitological characteristics of ZVL with special focus on the cellular and humoral canine immune response and review state-of-the-art vaccine development against human and canine visceral leishmaniasis. Experimental vaccination against leishmaniasis has evolved from the practice of leishmanization with living parasites to vaccination with crude lysates, native parasite extracts to recombinant and DNA vaccination. Although more than 30 defined vaccines have been studied in laboratory models no human formulation has been licensed so far; however three second-generation canine vaccines have already been registered. As expected for a zoonotic disease, the recent preventive vaccination of dogs in Brazil has led to a reduction in the incidence of canine and human disease. The recent identification of several Leishmania proteins with T-cell epitopes anticipates development of a multiprotein vaccine that will be capable of protecting both humans

  16. 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

  17. Ultrasonographic findings of uterine myoma

    International Nuclear Information System (INIS)

    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

    2009-02-01

    Sufficient uteroplacental blood flow is essential for normal pregnancy outcome and is accomplished by the coordinated growth and remodeling of the entire uterine circulation, as well as the creation of a new fetal vascular organ: the placenta. The process of remodeling involves a number of cellular processes, including hyperplasia and hypertrophy, rearrangement of existing elements, and changes in extracellular matrix. In this review, we provide information on uterine blood flow increases during pregnancy, the influence of placentation type on the distribution of uterine vascular resistance, consideration of the patterns, nature, and extent of maternal uterine vascular remodeling during pregnancy, and what is known about the underlying cellular mechanisms.

    Full Text Available Uterine sarcomas are rare tumours of mesodermal origin. Malignant change occurring in uterine fibroid is termed as leiomyosarcoma. They constitute around 2-6 % uterine malignancies and 25-36% of uterine sarcomas1. The tumour is common in women between the age group 40-50 years. It has an aggressive course and usually metastasis goes to the lungs. The prognosis for women with uterine sarcoma primarily depends on the extent of disease at the time of diagnosis and mitotic index3. Women with tumor size >5 cm in maximum diameter have poor prognosis. These tumours should be diagnosed and managed with no delay and must be followed vigilantly as the rate of recurrence and metastasis is very high.

    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.

    International Nuclear Information System (INIS)

    Uterine fibroids are the most common benign female tumours during reproductive age. The traditional treatment for this condition is typically hysterectomy. However, there are new technologies on the rise, such as Uterine Artery Embolisation and Magnetic Resonance-guided Focused Ultrasound which are directed towards a minimally invasive or even noninvasive treatment of uterine fibroids. These modern procedures allow for a fast recovery and preservation of fertility. In this work, we presented these alternative procedures and highlighted their and limitations. (authors)

    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.

    Full Text Available Cervical agenesis or dysgenesis is an extremely rare congenital anomaly. Patients with congenital absence of the cervix present with primary amenorrhea and infertility. Though it poses a diagnostic challenge to the clinician, correct diagnosis prior to surgery is possible with the help of ultrasound. Early diagnosis offers significant advantages in patient care and effective presurgical planning. This case report reviews two cases of cervical agenesis diagnosed with the help of ultrasound and later confirmed with the help of MRI. Ultrasonography is the modality of choice to define the internal genital anatomy and helps us to classify the level of obstruction or aplasia in obstructive uterine anomalies.

    Linton, J K; Sertich, P L

    2016-09-01

    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

    A seven-year-old entire female, mixed-breed dog, weighing 19 kg, was presented with a 2-day history of abdominal distension, reduced appetite and general dullness. Abdominal palpation revealed a large mass. Radiography showed a large mass occupying the left mid-abdominal area and convoluted loops of tubular fluid opacity occupying the right mid-abdominal area. Ultrasonography revealed a large heterogeneous mass with an anechoic area and some hyperechoic foci, indicative of calcification, in the mid-abdominal area. Furthermore, hypoechoic areas were found in the middle and caudal abdominal area and were presumed to be the fluid-filled uterine horns. At laparotomy, a 10·5×14·5-cm firm mass was found in the uterine body, while the uterine horns were filled with a thick red-brownish exudate; ovariohysterectomy was subsequently performed. A diagnosis of uterine leiomyosarcoma associated with pyometra was established by histopathology and immunohistochemistry. PMID:21265853

    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.

    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.

    2010-01-01

    In recent years, canine genetics had made huge progress. In 1999 the first complete karyotype and ideogram of the dog was published. Several linkage and RH maps followed. Using these maps, sets of microsatellite markers for whole genome scans were compiled. In 2003 the sequencing of the DNA of a female Boxer began. Now the second version of the dog genome assembly has been put online, and recently, a microchip SNP array became available. Parallel to these developments, some causal mutations for different traits have been identified. Most of the identified mutations were responsible for monogenic canine hereditary diseases. With the tools available now, it is possible to use the advantages of the population structure of the various dog breeds to unravel complex genetic traits. Furthermore, the dog is a suitable model for the research of a large number of human hereditary diseases and particularly for cancer genetics, heart and neurodegenerative diseases. There are some examples where it was possible to benefit from the knowledge of canine genetics for human research. The search for quantitative trait loci (QTL), the testing of candidate genes and genome-wide association studies can now be performed in dogs. QTL for skeletal size variations and for canine hip dysplasia have been already identified and for these complex traits the responsible genes and their possible interactions can now be identified.

  6. 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)

    Full Text Available Background. Uterine inversion is a rare, but life threatening, obstetrical emergency which occurs when the uterine fundus collapses into the endometrial cavity. 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.

    2012-07-01

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

    Background Uterine arterial embolization (UAE) is a safe and effective therapy for symptomatic uterine leiomyoma. This study was to assess the effectiveness and the feasibility of pingyangmycin-lipiodol emulsion (PLE) for the management of symptomatic uterine leiomyoma.Methods One hundred consecutive patients (aged 21-53 years, with 38 in average) with symptomatic uterine leiomyoma underwent superselective UAE with PLE. Clinical symptoms of the patients (including menorrhagia, bulk-related symptoms, and postprocedure-related abdominal pain) and the changes in uterine volume and tumor size after the embolization were analyzed. The patients were followed up for 8-21 months (mean, 15 months).Results Ninety-nine patients (99%, 99/100) were interviewed in their first menses circle after embolization, showing improvements in their abnormal bleeding and bulk-related symptoms to some extent. Imagiological results during follow-up showed a mean of 48% reduction in uterine volume at 6 months and a mean of 75% reduction in tumor size at 9 months. Eighty-three percent of the patients reported complete resolution of postprocedure pain within 7 days.Conclusions PLE is effective in the management of uterine leiomyoma, having superiority in alleviating postprocedure-related pain.

    International Nuclear Information System (INIS)

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

    2014-06-01

    Full Text Available Uterine vascular lesions in the form of arteriovenous malformation or pseudo aneurysm are rare but potential life-threatening source of bleeding. A high index of suspicion and accurate diagnosis of the condition in a timely manner are essential because instrumentation that is often used for other causes of uterine bleeding can lead to massive hemorrhage. We describe two cases of uterine vascular malformation, one presenting as postabortal hemorrhage and other as postpartum hemorrhage. Case one presented as postabortal hemorrhage after induced abortion following dilatation and curettage. Case two presented as delayed postpartum hemorrhage after six weeks following cesarean section. In both cases diagnosis of uterine arteriovenous malformation was made on Doppler ultrasonography which was subsequently confirmed on pelvic angiography. The embolization of affected uterine arteries was performed successfully in both cases. Uterine vascular lesion should be suspected in patient with abnormal vaginal bleeding, especially who has recent medical history of induced abortion or dilatation and curettage or cesarean section and so on. Although angiography remains the gold standard for making diagnosis, Doppler ultrasonography is also a good noninvasive technique for the same. Uterine artery embolization offers a safe and effective treatment. [Int J Reprod Contracept Obstet Gynecol 2014; 3(3.000: 749-753

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

    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

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...

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

    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.

    In this thesis some recent technological developments in human surgery are evaluated for their potential use in veterinary medicine by introducing them as surgical innovations for canine gonadectomy. Barbed sutures achieve wound apposition without surgical knot tying and thus avoid knot-associated negative consequences (lengthy placement, impaired wound healing around bulky knots, and the effect of unsightly knots on cosmetics). A study in 9 dogs found that celiotomy closure was easily achiev...

  2. Genome Sequence of Canine Herpesvirus.

    Directory of Open Access Journals (Sweden)

    Konstantinos V Papageorgiou

    Full Text Available Canine herpesvirus is a widespread alphaherpesvirus that causes a fatal haemorrhagic disease of neonatal puppies. We have used high-throughput methods to determine the genome sequences of three viral strains (0194, V777 and V1154 isolated in the United Kingdom between 1985 and 2000. The sequences are very closely related to each other. The canine herpesvirus genome is estimated to be 125 kbp in size and consists of a unique long sequence (97.5 kbp and a unique short sequence (7.7 kbp that are each flanked by terminal and internal inverted repeats (38 bp and 10.0 kbp, respectively. The overall nucleotide composition is 31.6% G+C, which is the lowest among the completely sequenced alphaherpesviruses. The genome contains 76 open reading frames predicted to encode functional proteins, all of which have counterparts in other alphaherpesviruses. The availability of the sequences will facilitate future research on the diagnosis and treatment of canine herpesvirus-associated disease.

    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.

    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.

    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.

    Full Text Available The puerperal uterine inversion is a rare and severe complication occurring in the third stage of labour. The exact mechanisms are unclear. However, extrinsic factors such as prolonged labour, umbilical cord traction, oxytocic use etc. have been mentioned. Other intrinsic factors such as primiparity, uterine hypotonia, different placental localizations, fundal location of a myoma or short umbilical cord have also been reported. The diagnosis of uterine inversion is mainly made on the basis of clinical symptoms which include haemorrhage, shock and a strong pelvic pain. The immediate treatment of the uterine inversion is required. A case of 23 years old, second gravida with one previous spontaneous first trimester abortion, who had a full term normal vaginal delivery but while trying to deliver the placenta after confirmation of placental separation clinically, uterine inversion was diagnosed immediately and manual repositioning of uterus was done under general anaesthesia. On the 6 th post natal day, during the routine postnatal rounds, uterus was not palpable per abdomen and a local examination revealed a mass at the introitus. A diagnosis of grade 3 sub-acute inversion was made and she was taken up for exploratory laparotomy. Reinsertion was done according to the Huntington technique by placing clamps on the round ligament, near its insertion on the uterus, and applying traction upwards while the assistant exerted traction on the contra lateral way through the vagina. As persistent atonicity and diffuse oozing was noted multiple Cho sutures were put over the uterus. Patient had an uneventful postnatal period. This is a rare scenario where the same patient had an acute inversion initially followed by sub-acute inversion. [Int J Reprod Contracept Obstet Gynecol 2016; 5(10.000: 3619-3621

    Full Text Available Abstract Canine and feline parasitic zoonoses have not been given high priority in China, although the role of companion animals as reservoirs for zoonotic parasitic diseases has been recognized worldwide. With an increasing number of dogs and cats under unregulated conditions in China, the canine and feline parasitic zoonoses are showing a trend towards being gradually uncontrolled. Currently, canine and feline parasitic zoonoses threaten human health, and cause death and serious diseases in China. This article comprehensively reviews the current status of major canine and feline parasitic zoonoses in mainland China, discusses the risks dogs and cats pose with regard to zoonotic transmission of canine and feline parasites, and proposes control strategies and measures.

  14. 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.

    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

    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.

    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

    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.

    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.

    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 A 36-year-old woman with 3 prior C-sections is diagnosed with a caesarean scar ectopic pregnancy. Despite receiving intramuscular and transvaginal methotrexate injection 2 months before presentation, the beta human chorionic gonadotropin was recorded to be 73 mIU/mL at the time of encounter. The patient complained of vaginal bleeding with a significant drop in hematocrit from 40% to 33%. Transvaginal ultrasound confirmed retroplacental hemorrhage and because of the patient's desire to retain fertility, interventional radiology was consulted to perform an uterine artery embolization. The uterine artery embolization was successful in achieving hemostasis and resulted in a decrease of betaHCG to 46 on postprocedure day 1 to <1 mIU/mL by postoperative week 3.

    Conclusion: Although metastasis of breast cancer to the genital organs is an uncommon event, breast carcinoma is still considered the second source of extragenital malignant metastasis to the uterus. Overall, the most popular sites for metastasis of breast carcinoma to the female reproductive system include the ovaries and the uterine cervix. The uterine corpus is the least common site involved. In this regard metastasis to a uterine leiomyoma is a rare event.

    Full Text Available A 47-year-old, single, Chinese woman presented with pain on the 1st day of menses for more than 30 years. Her dysmenorrhea worsened over years and underwent a total abdominal hysterectomy and bilateral salpingooophorectomy. The myometrium showed trabeculated appearance, and there were adhesions between ovaries and fallopian tubes. A pale solid brownish mass measuring 1.5 cm and times; 1 cm and times; 0.6 cm with fibrous whitish cut surfaces was present on the lateral wall of the uterus in the lower uterine segment. Histologically, adenomyosis and left ovarian endometriosis were confirmed. The lateral uterine wall nodule showed a tubular structure lined by ciliated pseudostratified columnar epithelium. Smooth muscle bundles were found around the entire tubular structure. Lobules of salivary type glands containing both serous and mucous cells are present. The pathological diagnosis of heterotopic respiratory mucosa (HRM was made. To our knowledge, this is the first reported case of HRM of the uterine corpus.

    2016-01-01

    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.

  17. Development of uterine neoplasms following radiotherapy for carcinoma of uterine cervix: a clinical evaluation of 47 patients

    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)

    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 The objective of this bibliographic essay, addressed both to veterinary clinicians and researchers, is to bring to mind the disease in terms of etiology, clinical manifestations and therapeutic and prophylactic management, as well as to remind the issues arising from recent researches. Depending on the virulence of the parasite species, body's immune response and therapeutic management approached, the plateau of disease evolution can be quite wide - from a favorable prognosis to a lethal outcome of the animal. The complexity of the pathogenic mechanism in babesiosis is due to soluble parasite antigens (SPA which, according to recent studies, have been obtained in vitro and then used as immunological product in disease prevention. Producing a vaccine against canine babesiosis with parasite antigens of local strains could play an important role to prevent the clinical expression of this disease in Romania.

    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.

    2013-07-01

    Canine parvovirus (CPV) enteritis has, since its emergence in 1978, remained a common and important cause of morbidity and mortality in young dogs. The continued incidence of parvoviral enteritis is partly due to the virus' capability to evolve into more virulent and resistant variants with significant local gastrointestinal and systemic inflammatory sequelae. This paper reviews current knowledge on historical-, signalment-, and clinical factors as well as several haematological-, biochemical- and endocrine parameters that can be used as diagnostic and prognostic biomarkers in CPV enteritis. These factors include season of presentation, purebred nature, bodyweight, vomiting, leukopaenia, lymphopaenia, thrombocytopaenia, hypercoagulability, hypercortisolaemia, hypothyroxinaemia, hypoalbuminaemia, elevated C-reactive protein and tumour necrosis factor, hypocholesterolaemia and hypocitrullinaemia. Factors contributing to the manifestations of CPV infection are multiple with elements of host, pathogen, secondary infections, underlying stressors and environment affecting severity and outcome. The availability of several prognosticators has made identification of patients at high risk of death and their subsequent targeted management more rewarding.

    Full Text Available Distraction osteogenesis method (Do in bone lengthening and rapid midpalatal expansion have shown the great ability of osteognic tissues for rapid bone formation under distraction force and special protocol with optimum rate of one millimeter per day. Periodontal membrane of teeth (PDM is the extension of periostium in the alveolar socked. Orthodontic force distracts PDM fibers in the tension side and then bone formation will begin.Objects: Rapid retraction of canine tooth into extraction space of first premolar by DO protocol in order to show the ability of the PDM in rapid bone formation. The other objective was reducing total orthodontic treatment time of extraction cases.Patients and Methods: Tweleve maxillary canines in six patients were retracted rapidly in three weeks by a custom-made tooth-born appliance. Radiographic records were taken to evaluate the effects of heavy applied force on canine and anchorage teeth.Results: Average retraction was 7.05 mm in three weeks (2.35 mm/week. Canines rotated distal- in by mean 3.5 degrees.Anchorage loss was from 0 to 0.8 mm with average of 0.3 mm.Root resorption of canines was negligible, and was not significant clinically. Periodontium was normal after rapid retraction. No hazard for pulp vitality was observed.Discussion: PDM responded well to heavy distraction force by Do protocol. Rapid canine retraction seems to be a safe method and can considerabely reduce orthodontic time.

    Full Text Available Maxillary canines are known as the cornerstones of mouth. They are considered to be important for esthetics and for functional occlusion. Any disturbance in the eruption process leading to an aberrant position will hamper esthetics as well as function. Orthodontic tooth movement of total buccally blocked-out canine is usually difficult as it is related with the problems of severe crowding, midline deviation, involvement of long root movement and risk of gingival recession. Such conditions can be treated orthodontically in various ways, but this clinical innovation helps to correct the buccally placed canines into the arch with a precise control of the canine in all the Three-dimensions (3D of space as well as providing maximum comfort to the patient by placing the canine loop on the palatal surface of the tooth, reducing soreness on the labial mucosa. It can be easily fabricated and activated at chairside for either simultaneous or sequential control in 3D.

  16. 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

    Intestinal obstruction is an uncommon surgical emergency during pregnancy that affects seriously the prognosis of gestation. The underlying cause can be identified in the majority of cases and usually consists of adhesions secondary to previous abdominal or pelvic surgery, followed in order of frequency by intestinal volvuli. In recent years there have been no reports in which the gravid uterus has been the cause of intestinal obstruction. We report the case of a woman in week 33 + 4 of pregnancy who developed extrinsic compression of the colon secondary to uterine rotation and pelvic impaction of the head of the fetus.

  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

    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

  4. 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

  5. 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

    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

    Estetrol is produced by the fetal liver and has been suggested to be a sensitive indicator of fetal well-being. Although the uterine vascular effects of estrogens (17 beta-estradiol, estriol, and estrone) have been extensively investigated in our laboratory and those of others, the ability of estetrol to dilate the ovine uterine vasculature is not presently known. The present experiment was designed to compare the vasoactivity of estetrol to that of a second pregnancy-associated estrogen, estriol. Five nonpregnant oophorectomized ewes were chronically instrumented with catheters in the femoral artery, femoral vein, uterine arteries, and electromagnetic flow probes on both uterine arteries. Upon recovering from operation, animals received unilateral intra-arterial (uterine) injections of either estriol (0.1, 0.3, 1, and 3 micrograms) or estetrol (1, 3, 10, and 30 micrograms). Ewes received only one dose of either estetrol or estriol daily and all doses were given in a randomized order. Uterine blood flow responses were continuously monitored and the time of onset, peak, and duration were recorded. The time of onset (38 +/- 2 minutes), time of peak response (75 +/- 1 minute), and duration (189 +/- 7 minutes) were approximately equal to those observed for estriol. On the basis of the data obtained in the present study we have determined that estetrol is 15 to 30 times less potent than estriol as a uterine vasodilator. PMID:6702941

    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

    Minimally invasive surgery, specifically robotic surgery, became a common technique used by gynecological surgeons over the last decade. The realization of the first human uterine transplantation commenced new perspectives in the treatment of uterine agenesia or infertility in women with history of hysterectomy at a young age. Robot-assisted technique may enhance the safety of the procedure by facilitating the microvascular anastomosis, vaginal anastomosis, and ligaments' fixation. This study proposes the formation of a multicenter collaboration group to organize a protocol with the aim to clarify the possible role of robotic surgery in uterine transplantation. PMID:26401113

    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 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.

  14. 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

    Aim. The purpose of this study was to investigate the prevalence of transmigrated canines in a north Indian population and association with gender, side, associated pathologies, and dental anomalies. Subjects and methods. The prospective study consisted of panoramic radiographs of 3000 patients from two dental colleges in north India. The panoramic radiographs were screened for radiographically identified position of the transmigrated tooth, retained canine, and other coexisting dental anomalies. Results. The overall prevalence of transmigrated canines (15 mandibular and 5 maxillary) was 0.66%. The prevalence of mandibular transmigrated canine was 0.5% and maxillary transmigrated canine was 0.16%. All the transmigrated canines were unilateral. The age range was 15–53 years (average age 24.1 years) and there were 12 males (60%) and 8 females (40%). Type 1 mandibular canine transmigration was the commonest type found in our study (10 cases), followed by types 2 and 4 (2 cases each) and 1 case of type 5 transmigration. Conclusion. The prevalence of transmigrated canines in the north Indian population was 0.66% and no gender predilection was evident. The transmigrated canines have a low complication rate (10.0%) and no correlation with other dental anomalies was found. Type 3 canine is the rarest form of mandibular canine transmigration.

  16. Transvaginal color Doppler imaging of uterine contractions in early pregnancies: Significance of uterine contractions in early pregnancy failure

    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.

    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.

    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.

    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

    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.

    The role of mast cells (MCs) in allergic reactions and parasitic infections is well established. Their involvement in host immune response against bacterial and viral infections is reported. In this study, investigation is made to determine if MCs are associated with Canine parvovirus-2 (CPV-2)-induced enteritis with crypt abscess (ECA). Mast cell count (MCC) was made on toluidine blue-stained intestinal sections from a total of 34 dogs. These included 16 dogs exhibiting ECA positive for CPV-2 and negative for Canine distemper virus and Canine coronavirus by immunohistochemistry and fluorescent antibody test, 12 dogs with inflammatory bowel disease (IBD), and 6 non-ECA/non-IBD (control) dogs. The average total MCC per high-power field in ECA (40.8 ± 2.2) and IBD (24.7 ± 2.1) was significantly higher (P .05), MCC was also higher in ECA than in IBD. The present study for the first time has documented significantly increased MCs in CPV-2-associated ECA as was previously reported for IBD, showing that MCs may also play an important role in CPV-2-associated ECA. Further studies involving more CPV-infected dogs are recommended to substantiate the findings.

    Full Text Available Abstract Background Teratomas are the commonest germ cell tumours and are most frequently found in the testes and ovary. Extragonadal teratomas are rare and mainly occur in midline structures. Uterine teratomas are extremely rare with only a few previous case reports, usually involving mature teratomas of the uterine cervix. Case Presentation We report an 82-year-old lady presenting with post-menopausal bleeding. Initial investigations revealed a benign teratoma of the uterus which was removed. Her symptoms persisted and a recurrent, now malignant, teratoma of the uterine corpus was resected at hysterectomy. Six months after surgery she relapsed with para-aortic lymphadenopathy and was treated with a taxane, etoposide and cisplatin-containing chemotherapy regimen followed by retroperitoneal lymph node dissection. Conclusion In this report we discuss the aetiology, diagnosis and management of uterine teratomas, and review previous case studies.

    1986-06-30

    We know close to nothing why preterm or adterm delivery in human being starts. Either it is the breakdown of mechanisms protecting the pregnancy when it is time for the baby to flee the no more adequate surrounding of the uterus, or the activation of substances starting uterine contractions. Most probable is the interaction between oxytocin and prostaglandines which leads to the onset of labour; the influence of the fetus on this procedure is discussed. Stimulation of contractions: Oxytocin given as infusion with or without foregoing priming by locally applied prostaglandines (exact supervision of uterine motility and the well-being of the fetus by CTG) and/or amniotomy. Infusions of Prostaglandines always cause uterine contractions ending with the expulsion of the fetus. Inhibition of uterine contractility: In cases of threatening premature delivery before during and after intraabdominal operations and fetal distress during term delivery nowadays Betamimetics are given. The application of alcohol is reserved for special cases.

    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

    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.

    Uterine leiomyomata (ULs) represent the most common tumor in women and can cause abnormal uterine bleeding, large pelvic masses, and recurrent pregnancy loss. Although the dependency of UL growth on ovarian steroids is well established, the relative contributions of 17β-estradiol and progesterone are yet to be clarified. Conventionally, estradiol has been considered the primary stimulus for UL growth, and studies with cell culture and animal models support this concept. In contrast, no resear...

    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

    A seroepidemiological survey of canine distemper virus (CDV) infection in Asian felids revealed that the prevalence of antibodies varied depending on region and, in some cases, exposure to dogs. The serologic pattern in cats with antibodies indicated that they had likely been exposed to field strains rather than typical CDV vaccine strains.

    Since 2006, canine distemper outbreaks have occurred in rhesus monkeys at a breeding farm in Guangxi, People’s Republic of China. Approximately 10,000 animals were infected (25%–60% disease incidence); 5%–30% of infected animals died. The epidemic was controlled by vaccination. Amino acid sequence analysis of the virus indicated a unique strain.

    Notoedric mange is a cutaneous ectoparasitic disease of cats caused by Notoedres cati, a mite belonging to the Sarcoptidae family. The disease occurs in felids, occasionally in other mammals and in humans. The canine form, even if cited by some authors, has never been documented. This report describes for the first time a case of notoedric mange in a dog.

    Several methods have been described for accomplishing distal movement of canines without losing posterior anchorage. An accepted method in canine retraction is the use of headgear with J hooks. Since it incorporates extraoral anchorage, it is most effective in maximum-anchorage cases. It was the purpose of this study to analyze the distribution of force transmitted to the alveolus and surrounding structures by means of photoelastic visualization, utilizing J hook headgear for maxillary canine retraction. A three-dimensional model representing a human skull was used. This model was constructed with different birefringent materials to simulate bone, teeth, and periodontal membranes. Three different vectors of force were applied representing high-, medium-, and low-pull headgear, which were placed at angles of 40, 20, and 0 degrees to the occlusal plane. The photoelastic analysis was made by means of a circular-transmission polariscope arrangement, and the photoelastic data were recorded photographically. The stress areas created by the three different vectors of force were associated with various degrees of canine tipping. This effect was greater with the low-pull force component than with the medium-pull traction. The high-pull headgear produced the least tipping tendency, being closer to a bodily movemment effect. Further, stresses were transmitted to deeper structures of the simulated facial bones; these regions were the frontozygomatic, zygomaticomaxillary, and zygomaticotemporal sutures.

    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.

    Full Text Available Abstract Introduction Malignant change in a leiomyoma or uterine fibroid is termed leiomyosarcoma. It arises from smooth muscle of the uterus and is a rare tumor that accounts for 2% to 5% of all uterine malignancies. Very few cases are reported in the literature. Our patient did not have any history of genital bleeding, which is the usual presentation in uterine sarcoma. We report an original case report of an unusual presentation of this rare tumor arising from the uterus. Case presentation A 40-year-old nulliparous woman of South Indian origin presented with a mass in her abdomen for one year with a rapid increase in size over the previous three months. Tumor marker CA-125 was raised, and a computed tomography scan showed a mass arising from the pelvis. An exploratory laparotomy was performed and the histopathology report confirmed the diagnosis of uterine leiomyosarcoma. Conclusion Because of their rarity, uterine sarcomas are not suitable for screening. Diagnosis is by histopathologic examination and surgery is the only treatment. The prognosis for women with uterine sarcoma primarily depends on the extent of disease at the time of diagnosis and the mitotic index.

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

    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

    2000-01-01

    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

  11. 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)

  12. 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).

  13. 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

  16. Early canine pregnancy--a battle for successful growth and angiogenesis.

    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

    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.

    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.

    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.

    This study provides the first report into immunohistochemical localization of Toll-like receptor (TLR) in the canine reproductive tract. TLR4 was investigated in endometrium during the estrous cycle and in pyometra. Pyometra is the most important pathological condition of the uterus due to bacterial infection in dogs. To protect against invading pathogens, the female reproductive tract has evolved immune mechanisms. TLRs are the cellular components of the afferent arm of the innate immune system. The expression of TLR4 was significantly higher in the endometrial stroma compared to the endometrial surface epithelium and glandular epithelium in proestrus. The glandular epithelium and stroma at the diestrous stage expressed TLR4 significantly higher than surface epithelium. Furthermore, when compared to other healthy groups, the glandular epithelium at diestrus also higher expressed TLR4 than other stages. The expression of TLR4 in the surface epithelium was higher in dogs with pyometra compared with all other groups. And, the surface epithelium of dogs suffering from pyometra also expressed TLR4 more intensely than the glandular epithelium. The innate immunity of infected canine endometrium response to bacterial infection is intensely extremely increased by the expression of TLR4. Furthermore, the different levels of TLR4 expression seems related to physiological changes in distinct cell types of endometrium, leukocytes populations, cytokines and sex hormones. PMID:21752456

    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.

    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

    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.

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.

  17. Uterine morphology and peristalsis in women with polycystic ovary syndrome

    International Nuclear Information System (INIS)

    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

    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.)

    Full Text Available We report a case of extramedullary hematopoiesis (EMH in uterine leiomyoma and associated numerous intravascular thrombi. A 29-year-old nulliparous female presented with heavy vaginal bleeding and a hematocrit of 22%. No bone marrow biopsy has been performed. She had a history of uterine leiomyomata and menorrhagia for a year. A transvaginal ultrasound confirmed the presence of a uterine leiomyoma. The patient was treated conservatively with oral contraceptive pills due to desire for fertility. However, she continued to have heavy vaginal bleeding and developed bilateral upper extremity deep vein thrombosis and multiple superficial vein thromboses after two months. An exploratory laparotomy with uterine myomectomy was performed. Gross examination of the specimen revealed a single nodular mass measuring 10.0×9.5×7.5 cm with a white-tan swirling cut surface. Microscopic examination revealed benign smooth muscle consistent with leiomyoma and numerous intravascular thrombi both with areas of EMH. Immunohistochemical stains confirmed the presence of all three benign lineages of hematopoietic cells. Occurrence of EMH in uterine leiomyoma and intravascular thrombi is very rare. It may be related to systemic hematopoietic stimulation due to severe chronic anemia and local presence of hematopoietic growth factors and/or cytokines.

    Full Text Available Fear of scar rupture is one of risks involved in a post caesarean pregnancy. This had led to an increased rate of repeat cesarean delivery in today′s times. Closure of the uterine incision is a key step in cesarean section, and it is imperative that an optimal surgical technique be employed for closing a uterine scar. This technique should be able to withstand the stress of subsequent labor. In the existing techniques of uterine closure, single or double layer, correct approximation of the cut margins, that is, decidua-to-decidua, myometrium to myometrium, serosa to serosa is not guaranteed. Also, there are high chances of inter surgeon variability. It was felt that if a suturing technique which ensures correct approximation of all the layers mentioned above with nil or minimal possibility of inter operator variability existed, there will not be any thinning of lower segment caesarean section (LSCS. Further, a scarred uterus repaired in this manner will be able to withstand the stress of labor in future. We hereby report a new technique for uterine closure devised by us, which incorporates a continuous modified mattress suture technique as a modification of the existing surgical technique of uterine closure.

  1. Physiological remodelling of the maternal uterine circulation during pregnancy.

    Science.gov (United States)

    Mandala, Maurizio; Osol, George

    2012-01-01

    Sufficient uteroplacental blood flow is essential for normal pregnancy outcome and is accomplished by the coordinated growth and remodelling of the entire maternal uterine vasculature. The main focus of this MiniReview is to provide information on upstream (pre-placental) maternal uterine vascular remodelling that facilitates gestational increases in uterine blood flow. Consideration of the three-dimensional pattern of remodelling (circumferential enlargement versus axial elongation), changes in vessel biomechanical properties, and underlying mechanisms [shear stress, nitric oxide, vascular endothelial growth factor (VEGF)/placental growth factor (PlGF), the renin-angiotensin system] and pathways (local versus systemic; venoarterial exchange) are provided using the rat as the principal animal model, although findings from other species are incorporated wherever possible to provide a comparative perspective. The process of maternal gestational uterine vascular remodelling involves a number of cellular processes and mechanisms, including trophoblast invasion, hyperplasia and hypertrophy, and changes in extracellular matrix composition. In addition, changes in cellular function, e.g. the secretory and contractile properties of smooth muscle and an up-regulation of endothelial vasodilatory influences may contribute to uteroplacental blood flow increases through changes in tone as well as in structure. Future studies aimed at better understanding the inter-relationship between changes in vessel structure (remodelling) and function (reactivity) would likely generate new mechanistic insights into the fascinating process of maternal gestational uterine vascular adaptation and provide a more physiological perspective of the underlying cellular processes involved in its regulation.

Peristaltic detection rate and frequency were significantly less for the endometriosis group than for the controls in the periovulatory phase only (p<0.05). Sustained contractions were recognized in 19/36 control subjects and in 13/26 endometriosis patients, but the difference was not significant. Uterine peristalsis appears to be suppressed during the periovulatory phase in patients with endometriosis, which may have an adverse effect on sperm transport. (orig.)

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

    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.

    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.

    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

    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).

    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

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

    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 motility was studied in the anestrous goats after a series of estradiol injections was given and after estradiol-plus-progesterone treatment was administered. Estradiol (0.1 mg/kg) given alone by intramuscular route every 6 hours for 4 continuous days produced only a moderate increase in the uterine contractions during treatment, but significantly higher amplitude and frequency of contractions occurred at 2 days after treatment was stopped. The same doses of estradiol administered for a 24-hour period and followed by 4 injections of progesterone (1.0 mg/kg) given intramuscularly once a day produced a moderate response during treatment, but depressed the amplitude and the frequency of contractions after the treatment was stopped. The results indicate that the tissues primed with estrogen produced a stimulatory effect after their estrogen contents diminished. Progesterone, likewise, produced inhibition after a decrease in the progesterone contents of the uterine tissue. PMID:944003

    2016-05-01

    Approximately 30% of women will experience abnormal uterine bleeding (AUB) during their life time. Previous terms defining AUB have been confusing and imprecisely applied. As a consequence, both clinical management and research on this common problem have been negatively impacted. In 2011, the International Federation of Gynecology and Obstetrics (FIGO) Menstrual Disorders Group (FMDG) published PALM-COEIN, a new classification system for abnormal bleeding in the reproductive years. Terms such as menorrhagia, menometrorrhagia, metrorrhagia, dysfunctional uterine bleeding, polymenorrhea, oligomenorrhea, and uterine hemorrhage are no longer recommended. The PALM-COEIN system was developed to standardize nomenclature to describe the etiology and severity of AUB. A brief description of the PALM-COEIN nomenclature is presented as well as treatment options for each etiology. Clinicians will frequently encounter women with AUB and should report findings utilizing the PALM-COEIN system. PMID:26969858

    2016-07-01

    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.

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

    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

    Full Text Available Recurrent spontaneous abortion affects 2%-5% of"ncouples. Uterine perfusion is considered as one of the"nfactors that influences the success of implantation."nDuring the normal menstrual cycle, the impedance"nto uterine artery blood flow diminishes progressively"nduring the luteal phase, reaching the lowest values"nin the period coinciding with the implantation time."nImpedance of uterine arteries is a good indicator of"nthe possibility of a subsequent pregnancy. High blood"nflow resistance is associated with a reduced conception"nrate and women with lower pulsatility index values"nhave the highest possibility of becoming pregnant. An"nimpaired uterine perfusion could play a major role in"nthe pathogenesis of recurrent spontaneous abortion. In"nthis study, we examined sixty women with recurrent"nspontaneous abortion and a control group including"nthirty normal women with at least one previous"nuncomplicated pregnancy and without history of any"nabortion.

    2016-08-01

    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.

    Two postpartum cows were used to study the ultrastructural changes of uterine endometrium by using scanning electron microscope. The results showed that the process of repair of uterine endometrium after calving was demonstrated by scanning electron microscope through a series of endometrium biopsy. Some part of the endometrium was damaged after calving and its adjacent endometrium cells became necrosis and exfoliated during the first 7 days post-partum;the cilium and microvillus of the epithelial cell in the undamaged area of the endometrium disappeared. By 26 days postpartum the damaged area reduced and the cilium and microvillus increased in their numbers. The damaged tissues were all repaired by day 60 postpartum.

    Management of Postpartal Haemorrhage (PPH) refractory to medical management continues to be a formidable condition, further compounded by unstable haemodynamic condition and associated coagulopathy, usually associated with this condition. Though surgical exploration is the usual therapeutic option for such patients, selective pelvic arterial embolisation is gaining the popularity in view of its safety and efficacy profile. Uterine preservation further adds to its advantages.We present our experience of managing 5 such patients with Uterine Artery Embolisation (UAE). The current status of UAE as therapeutic modality for management of refractory PPH is discussed.

    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

    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

    Full Text Available Background/Objectives : To evaluate the safety, efficacy an d complication rate of uterine artery embolization in symptomatic fibroid patients in Iran. Patients and Methods: A hundred and two patients aged 20-48 years (mean age: 35.7 ±6.4 years with symptomatic fibroids entered th e study from September 2001 to November 2004. The most common presenting symptom was increased menstrual bleeding, which occurred in 74.5% of all patients. Urinary symptoms occurred in 43%, and bulk-related symptoms were seen in 63.7 % of our patients. We performed bilateral UAE (uterine artery em bolization using PVA (pol yvinyl alcohol particles (500-710 micron and assessed the patients before UAE and at regular follow- ups at 1, 3, 6 and 12-month intervals by questionnaires / interviews and ultrasound. MRI without gadolinium (Gd-DTPA injection was done before emboliz ation and at 6 and 12 months after the procedure. Results: By Friedman test, sequential follow-up (up to 12 months showed that the vaginal bleeding severity significantly decreased (p <0.0001, with menorrhagia resolving in 59.4% of patients at 1 month, and in 69% at 12 months. The mean uterus volume decreased 38.5 ±30% after 12 months .The paired t-test showed that dominant fibroid volume changed from 273.7±439.2 cm3 to 112.1±141.6 cm3 at month 6 (n=58, p=0.001 and from 246.1±314.5 cm3 to 70.1±73.5 cm3 at month 12 (n=41, p<0.0001 . The initial size of the fibroids did not affect the success rate. Conclusion: The study showed the high efficacy of UAE in controlling fibroid related symptoms, with only few complications.

    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

    The aim of the study was the evaluation of morphology and immunophenotype of canine (19 cases) and feline (7 cases) extramedullary plasmacytomas. Tumours, located in skin, oral cavity and spleen were surgically excised, fixed and processed for histopathology and immunohistochemistry (CD79α, CD18, proliferating cell nuclear antigen, metallothionein). Histologically, tumours were classified into mature, cleaved, asynchronous, polymorphous blastic, hyalin, or monomorphous blastic type. All evaluated tumours showed cytoplasmic expression of CD79α antigen. The expression of CD18 was observed in canine cutaneous and splenic tumours. In canine tumours expression of metallothionein was low to moderate, while in feline plasmacytomas - absent or low. In canine tumours, the mitotic index and proliferating cell nuclear antigen index were positively correlated with the expression of metallothionein. In feline tumours no correlation between mitotic index, proliferating cell nuclear antigen and metallothionein was found. This is the first study describing expression of metallothionein in canine and feline extramedullary plasmacytoma. PMID:27487508

    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

    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.

    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

    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

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.

  10. Intrauterine Adhesions following Conservative Treatment of Uterine Fibroids

    Directory of Open Access Journals (Sweden)

    Pietro Gambadauro

    2012-01-01

    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.

    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.

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.

    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.

    Serum neutralisation test (SNT) has been established for evaluating canine distemper vaccination, but until now SNT was rarely used due to the need for continuous tissue culture facilities and requires 3 days to perform. For detecting antibody to canine distemper virus, an enzyme-linked immunosorbent assay (ELISA) is relatively simple and rapid seroassay. ELISA for canine immunoglobulin (Ig) G antibodies to canine distemper virus (CDV) was developed by using Onderstepoort strain of canine dis...

    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.

    The concentration of lactoferrin was measured in canine sera from groups of healthy male dogs as well as pregnant and non-pregnant female dogs and was compared with that of bitches with pyometra. Lactoferrin concentrations were higher in bitches with pyometra. The role of elevated lactoferrin concentrations in the suppression of lymphocyte activity was examined in sera from bitches with pyometra in a series of investigations. Although the sera from bitches with pyometra were capable of suppressing lymphocyte activity, lactoferrin was not found to be involved in this action. PMID:19754566

    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

  3. Uterine activity, sperm transport, and the role of boar stimuli around insemination in sows.

    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

    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

    Detecting preterm labor as early as possible is important because tocolytic drugs are much more likely to delay preterm delivery if administered early. Having good information on the real risk of premature labor also leads to fewer women who do not need aggressive treatment for premature labor threat. Currently, one of the most promising ways to diagnose preterm labor threat is the analysis of the electrohysterogram (EHG). Its characteristics have been related to preterm labor risk but they have not proven to be sufficiently accurate to use in clinical routine. One of the reasons for this is that the physiology of the pregnant uterus is insufficiently understood. Models already exist in literature that simulate either the electrical or the mechanical component of the uterine smooth muscle. Few include both components in a co-simulation of electrical and mechanical aspects. A model that can represent realistically both the electrical and the mechanical behavior of the uterine muscle could be useful for better understanding the EHG and therefore for preterm labor detection. Processing the EHG considers only the electrical component of the uterus but the electrical activity does not seem to explain by itself the synchronization of the uterine muscle that occurs during labor and not at other times. Recent studies have demonstrated that the mechanical behavior of the uterine muscle seems to play an important role in uterus synchronization during labor. The aim of the proposed study is to link three different models of the uterine smooth muscle behavior by using co-simulation. The models go from the electrical activity generated at the cellular level to the mechanical force generated by the muscle and from there to the deformation of the tissue. The results show the feasibility of combining these three models to model a whole uterus contraction on 3D realistic uterus model. PMID:27567400

    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.

    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.

    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 micrometer 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, I review the biomechanics of bacterial motility and look ahead to future challenges.

    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 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

    Objective:To study the canine echinococcosis by coproantigen ELISA method. Methods:During the present investigation experimental infection was established using evaginated worms of Echinococcus granulosus (E. granulosus). To check cross reactivity two pups were infected with Taenia hydatigena(T. hydatigena). In order to detect the presence of antigen, hyperimmune sera were raised against excretory-secretory products of adult worms E. chinococcus granulosus. Faecal sample collected either from experimentally infected pups or from other sources were heated at 70℃to detect heat stable soluble antigen. Results:Pups harbouring less than 104 worms showed negative results. Samples collected from 14 days onwards from experimentally infected animals harbouring more than 104 worms showed positive value. The maximum positive samples were detected in samples collected from in and around slaughter house and the least number of samples were detected positive maintained by dog squad. Conclusions:The affinity purified IgG exhibited promising results for detection of canine echinococcosis by indirect ELISA.

    Full Text Available Canine parvovirus is an acute and fatal viral disease in dogs. 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.

    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

    Full Text Available We face difficulty in individual canine retraction in the bracket system lacking power arms on the canines. When orthodontic force is applied through the center of resistance (CR, then, tooth translation ensues. Forces applied at a distance from the CR create a moment that tends to rotate and tip the tooth. The tendency of tipping is increased in the bracket system lacking power arm, since, force is applied more occlusally. Hence, we have designed a chair side custom made jig to retract the canines individually.

    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.

    The aim of this study was to verify the efficacy of color Doppler ultrasonography for diagnosis of degree and duration of uterine torsion in buffaloes. In Assiut province/Upper Egypt, 65 buffaloes (37 with uterine torsion, 28 with normal late pregnancy) were examined clinically and using Doppler ultrasonography. The Doppler indices including resistance index (RI), pulsatility index (PI), time-averaged maximum velocity (TAMV), and blood flow volume (BFV) in the arteries ipsilateral to the uterine torsion (IPUT) and in arteries contralateral to the uterine torsion (COUT) were recorded. Methods of correction were documented along with dam and calf survival. Torsion was recorded postcervically with vaginal involvement in 35/37 (94.6%) of the cases. The degrees of uterine torsion were light and high in 9/37 (24.3%) and 28/37 (75.7%) of the cases, respectively (P = 0.001). Right uterine torsion was present in 36/37 (97.3%) of the cases (P = 0.0001). Pulsatility index, RI, TAMV, and BFV in IPUT and COUT did not differ significantly (P > 0.05) in normal late pregnancy. The PI and RI in IPUT were significantly higher (P perfusion. In conclusion, depicting blood flow within the middle uterine artery using color Doppler sonography could be helpful in correct diagnosis of duration and degree of uterine torsion and concurrently predicting the viability of the fetus and dam.

    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.

    Odontogenic infection may be dangerous; especially when life-threatening complications occur. Infection spreads through the bone and periosteum toward nearby or more distant structures and spaces. Canine fossa abscess is an odontogenic infection that can lead to life-threatening complications. Successful treatment requires early recognition, determination of etiological factors, and proper medical and surgical management. The aim of this paper is to emphasize different and rare etiological fa...

    Fifty dogs with bilateral otitis externa were studied over a 10-month period. The exudates of both external ears were obtained, using sterile swabs, and microorganisms were isolated according to standard microbiological techniques. Antimicrobial susceptibility testing of Staphylococcus intermedius was done by the agar diffusion method. There was bacterial and/or fungal growth in all of the samples. These were all polymicrobial infections. Anaerobic bacteria were not isolated in any sample. The most common pathogens isolated were S. intermedius and Malassezia pachydermatis. A statistically significant difference (P intermedius strains to penicillin, ampicillin, erythromycin, tetracycline, and clindamycin were found. The results suggest that in bilateral canine otitis externa, each ear should be cultured separately and considered as separate units.

    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

    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.

    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.

  7. Periodontal ligament distraction: A simplified approach for rapid canine retraction

    2012-01-01

    Full Text Available Distraction osteogenesis is a method of inducing new bone formation by applying mechanical strains on preexisting bone. The process of osteogenesis in the periodontal ligament during orthodontic tooth movement is similar to the osteogenesis in the midpalatal suture during rapid palatal expansion. A new concept of "distracting the periodontal ligament" is proposed to elicit rapid canine retraction in two weeks. At the time of first premolar extraction, the interseptal bone distal to the canine was undermined with a bone bur, grooving vertically inside the extraction socket along the buccal and lingual sides and extending obliquely toward the socket base. Then, a tooth-borne, custom-made, intraoral distraction device was placed to distract the canine distally into the extraction space. It was activated 0.5 mm/day, immediately after the extraction. Canine was distracted 6.5 mm into the extraction space within two weeks.

    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

    2016-01-01

    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.

    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

    A rat uterine horn model of genital tract wound healing is described. Healing was reflected by acquisition of strength and elasticity, measured by burst strength (BS) and extensibility (EX), respectively. A tensiometer (Instron Corp., Canton, MA) was used to assess these characteristics in castrated and estrogen-supplemented or nonsupplemented animals. While the horn weights (HW), BS, and EX of contralateral horns were not significantly different, the intra-animal variation of HW was 7.2%, BS was 17.7% and EX was 38.2%. In a second experiment, one uterine horn was divided and anastomosed, and the animal given estrogen supplementation or a placebo pellet. Estrogen administration was found to increase BS and EX of anastomosed horns prior to 14 days, but had no beneficial effect at 21 or 42 days. The data suggest that estrogen may be required for optimal early healing of genital tract wounds.

    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.

    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.

    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.

    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.

    2016-01-01

    Objective:To compare the expression of TAK1 in normal myometrium and uterine leiomyoma tissue, and explore the relationship between these molecules and pathogenesis of uterine leiomyoma. Methods:Formaldehyde-fixed, paraffin-embedded specimen from 76 patients with uterine leiomyoma and normal myometrium adjacent were obtained from our hospital. The expression of TAK1 was detected by immunohistochemical staining and PCR analysis. Results:The expression of protein and mRNA levels TAK1 in uterine leiomyoma tissues were significantly increased when compared with normal myometrium, but not related to the number of leiomyoma. Furthermore, TAK1 expression was associated with the size of uterine leiomyoma. Conclusion:The present results suggest that the abundant expression of TAK1 protein may have a molecular basis characteristic of leiomyomas in the human uterus, and TAK1 may be a therapeutic target for the treatment of uterine leiomyoma.

  1. 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)

    2011-09-01

    Full Text Available We report two cases of women with a previous cesarean performed before active labor at 29 weeks of gestation who underwent sonographic measurement of the lower uterine segment (LUS at 36 weeks' gestation in their subsequent pregnancy. In both cases, uterine scar defect was detected on the upper part of the LUS, at ~9 to 11 cm from the cervical os, and was only visualized by the transabdominal approach. We suggest that early gestational age and the absence of labor at previous cesarean can lead to a higher uterine scar location on the LUS and, therefore, increase the risk of uterine rupture in subsequent pregnancy. The heterogeneity of uterine scar location could explain discrepancies observed in studies using the transabdominal versus the transvaginal approach or both regarding the predictive value of LUS measurements for uterine rupture.

  7. Genomic instability and telomere fusion of canine osteosarcoma cells.

    Directory of Open Access Journals (Sweden)

    Junko Maeda

    Full Text Available Canine osteosarcoma (OSA is known to present with highly variable and chaotic karyotypes, including hypodiploidy, hyperdiploidy, and increased numbers of metacentric chromosomes. The spectrum of genomic instabilities in canine OSA has significantly augmented the difficulty in clearly defining the biological and clinical significance of the observed cytogenetic abnormalities. In this study, eight canine OSA cell lines were used to investigate telomere fusions by fluorescence in situ hybridization (FISH using a peptide nucleotide acid probe. We characterized each cell line by classical cytogenetic studies and cellular phenotypes including telomere associated factors and then evaluated correlations from this data. All eight canine OSA cell lines displayed increased abnormal metacentric chromosomes and exhibited numerous telomere fusions and interstitial telomeric signals. Also, as evidence of unstable telomeres, colocalization of γ-H2AX and telomere signals in interphase cells was observed. Each cell line was characterized by a combination of data representing cellular doubling time, DNA content, chromosome number, metacentric chromosome frequency, telomere signal level, cellular radiosensitivity, and DNA-PKcs protein expression level. We have also studied primary cultures from 10 spontaneous canine OSAs. Based on the observation of telomere aberrations in those primary cell cultures, we are reasonably certain that our observations in cell lines are not an artifact of prolonged culture. A correlation between telomere fusions and the other characteristics analyzed in our study could not be identified. However, it is important to note that all of the canine OSA samples exhibiting telomere fusion utilized in our study were telomerase positive. Pending further research regarding telomerase negative canine OSA cell lines, our findings may suggest telomere fusions can potentially serve as a novel marker for canine OSA.

    Epidemiology of canine enteric infections was studied. Rectal swabs collected from 95 dogs presented at animal hospitals during a period from January to June of 2000 were examined for enteric pathogens, including viruses and Giardia lamblia (G. lamblia). Most frequently detected in both diarrheal and normal feces were canine coronavirus (55.4%) and G. lamblia (48.2%). Canine parvovirus type 2 (CPV-2) was specifically associated with diarrheal cases and CPV-2b was the predominant antigenic type. Although canine rotavirus, canine adenovirus, and canine distemper virus were also detected in a small number of diarrheal cases, no evidence for calicivirus infection was obtained. PMID:11411507

    Transmigration of canine is a rare phenomenon. The prevalence of transmigration of mandibular canine has been found to be only 0.14%-0.31%. The treatment of impacted transmigrated canine is very complicated if it is diagnosed at a later stage. We report 4 cases of transmigration of mandibular canine and review the literature regarding the etiology and treatment. Panoramic radiograph should be taken during the mixed dentition period if the mandibular canine has not erupted from more than one year from its normal chronological age of eruption as intraoral periapical radiograph examination will not always detect an impacted or transmigrated canine.

    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.

    The purpose of this study was to investigate the clinical findings, treatment, and outcome of patients with glassy cell carcinoma of cervix. We reviewed all cases of glassy cell carcinoma of the uterine cervix confirmed and treated at the Dongsan Medical Center, Keimyung University, between January 1993 and December 2005. There were 7 cases with histopathologically confirmed gassy cell carcinoma. A tumor was diagnosed as glassy cell carcinoma if over 50% of the tumor cell type displayed glassy cell features. Six patients with stage IB had radical hysterectomy and bilateral pelvic node dissection, and 2 of them received adjuvant external pelvic irradiation with concurrent chemotherapy. Remaining one patient with stage IIA had curative concurrent chemoradiotherapy with external pelvic irradiation and brachytherapy. There were 7 patients diagnosed as glassy cell carcinoma among the 3,745 (0.2%) patients of carcinoma of uterine cervix. The mean age of 7 patients was 44 years with range of 35 to 53 years of age. The most frequent symptom was vaginal bleeding (86%). By the punch biopsy undertaken before treatment of 7 cases, 2 only cases could diagnose as glassy cell carcinoma of uterine cervix, but remaining of them confirmed by surgical pathological examination. The mean follow up duration was 73 months with range of 13 to 150 months. All 7 patients were alive without disease after treatment. Glassy cell carcinoma of the uterine cervix is a distinct clinicopathologic entity that demonstrates an aggressive biologic behavior. However for early-stage disease, we may have more favorable clinical outcome with radical surgery followed by chemoradiotherapy.

    International Nuclear Information System (INIS)

    Adenomyosis is a common obstetric and gynecological disease. The main clinical symptoms include menorrhagia, menostaxis and progressive exacerbated dysmenorrhea. The main treatments currently used to deal with this disease are surgery and medication, but both have certain advantages. With the development of interventional radiology and the deepening of clinical researches concerning uterine artery embolization for adenomyosis, interventional therapy has become a major therapeutic method for adenomyosis in clinical practice.

    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.

  4. Luteal regression vs. prepartum luteolysis: regulatory mechanisms governing canine corpus luteum function.

    Science.gov (United States)

    Kowalewski, Mariusz P

    2014-04-01

    Canine reproductive physiology exhibits several unusual features. Among the most interesting of these are the lack of an acute luteolytic mechanism, coinciding with the apparent luteal independency of a uterine luteolysin in absence of pregnancy, contrasting with the acute prepartum luteolysis observed in pregnant animals. These features indicate the existence of mechanisms different from those in other species for regulating the extended luteal regression observed in non-pregnant dogs, and the actively regulated termination of luteal function observed prepartum as a prerequisite for parturition. Nevertheless, the supply of progesterone (P4) depends on corpora lutea (CL) as its primary source in both conditions, resulting in P4 levels that are similar in pregnant and non-pregnant bitches during almost the entire luteal life span prior to the prepartum luteolysis. Consequently, the duration of the prolonged luteal phase in non-pregnant bitches frequently exceeds that of pregnant ones, which is a peculiarity when compared with other domestic animal species. Both LH and prolactin (PRL) are endocrine luteotrophic factors in the dog, the latter being the predominant one. In spite of increased availability of these hormones, luteal regression/luteolysis still takes place. Recently, possible mechanisms regulating the expression and function of PRL receptor have been implicated in the local, i.e., intraluteal regulation of PRL bioavailability and thus its steroidogenic potential. Similar mechanisms may relate to the luteal LH receptor. Most recently, evidence has been provided for an autocrine/paracrine role of prostaglandin E2 (PGE2) as a luteotrophic factor in the canine CL acting at the level of steroidogenic acute regulatory (STAR)-protein mediated supply of steroidogenic substrate, without having a significant impact on the enzymatic activity of the respective steroidogenic enzymes, 3β-hydroxysteroid-dehydrogenase (3βHSD, HSD3B2) and cytochrome P450 side

    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

  9. Why segment the maxilla between laterals and canines?

    2016-02-01

    Full Text Available Introduction: Maxillary surgery on a bone segment enables movement in the sagittal and vertical planes. When performed on multiple segments, it further provides movement in the transverse plane. Typical sites for interdental osteotomies are between laterals and canines, premolars and canines, or between incisors. Additionally, osteotomies can be bilateral, unilateral or asymmetric. The ability to control intercanine width, buccolingual angulation of incisors, and correct Bolton discrepancy are some of the advantages of maxillary segmentation between laterals and canines. Objective: This article describes important features to be considered in making a clinical decision to segment the maxilla between laterals and canines when treating a dentoskeletal deformity. It further discusses the history of this surgical approach, the indications for its clinical use, the technique used to implement it, as well as its advantages, disadvantages, complications and stability. It is therefore hoped that this paper will contribute to disseminate information on this topic, which will inform the decision-making process of those professionals who wish to make use of this procedure in their clinical practice. Conclusions: Segmental maxillary osteotomy between laterals and canines is a versatile technique with several indications. Furthermore, it offers a host of advantages compared with single-piece osteotomy, or between canines and premolars.

    Full Text Available Abstract Background There are numerous reports linking Chlamydia infection to human coronary atherosclerosis. However, there is a lack of data regarding this correlation in dogs and cats, and there are no reports investigating coronary arteriosclerosis and Chlamydia in these species. The aim of the present study was to examine whether there is a correlation between canine and feline spontaneous atherosclerosis or arteriosclerosis and the presence of Chlamydia. Archived histopathological samples of dogs (n = 16 and cats (n = 13 with findings of atherosclerosis or arteriosclerosis in heart tissue were examined for the presence of Chlamydiaceae using real-time PCR, ArrayTube Microarray and immunohistochemistry. Additionally, arteriosclerotic lesions of all cases were histologically classified and graded. Results Both canine atherosclerotic cases, and all 14 canine arteriosclerotic cases were negative for Chlamydia. Only one of the 13 arteriosclerotic feline cases was positive for Chlamydia by real-time PCR, revealing C. abortus by ArrayTube Microarray. To our knowledge, this is the first description of C. abortus in a cat. Overall, the type and grade of canine and feline arteriosclerotic lesions revealed similarities, and were predominantly moderate and hyperplastic. Conclusions These findings suggest that there is no obvious correlation between canine and feline coronary arteriosclerosis and the presence of Chlamydia. In order to draw final conclusions about the correlation between Chlamydia and canine atherosclerosis, examination of more samples is required.

    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.

    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.

    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.

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

    Objective To investigate the expression of TRAIL in mouse uterine endometrium during embryo implantation and its role in the apoptosis of decidual cells.Methods Expression of TRAIL in uterine endometrium of pregnant mouse from d 1 to d 8 was detected with RT-PCR and immunohistochemistry.Results The expressed level of TRAIL mRNA in uterine endometrium of pregnant mouse from d 1 to d 8 was higher during embryo implantation than that prior to embryo implantation (P<0. 05). No expression of TRAIL protein in mouse utrine endometrium was detected through d 1 to d 3. However, TRAIL protein was found in the luminal epithelial cells to which embryos attached on d 4. Moreover, TRAIL was expressed solely in decidual cells around invadting embryos through d 5 to d 6 while in trophoblastic cells adjacent to decidua through d 7 to d 8.Conclusion Apoptosis of luminal epithelial cells of endometrium induced by TRAIL could be one of mechanisms with which embryos penertrated the epithelial barrier,and apoptosis of both decidual cells and trophoblastic cells induced by TRAIL may play an important role during accruate invasion of trophoblastic cells.

    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.

    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.

    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 8 × 6 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. PMID:23533863

  5. Chronic hypoxia during gestation enhances uterine arterial myogenic tone via heightened oxidative stress.

    Full Text Available Chronic hypoxia during gestation has profound adverse effects on the adaptation of uteroplacental circulation in pregnancy. Yet, the underlying mechanisms are not fully understood. The present study tested the hypothesis that enhanced production of reactive oxygen species (ROS in uterine arteries plays a critical role in the maladaptation of uterine circulation associated with chronic hypoxia. Uterine arteries were isolated from nonpregnant and near-term pregnant sheep maintained at sea level (~300 m or exposed to high-altitude (3801 m hypoxia for 110 days. Hypoxia significantly increased ROS production in uterine arteries of pregnant, but not nonpregnant, sheep. This was associated with a significant increase in NADPH oxidase (Nox 2, but not Nox1 or Nox4, protein abundance and total Nox activity in uterine arteries of pregnant animals. Chronic hypoxia significantly increased pressure-dependent uterine arterial myogenic tone in pregnant sheep, which was abrogated by a Nox inhibitor apocynin. Additionally, the hypoxia-induced increase in myogenic reactivity of uterine arteries to phorbol 12,13-dibutyrate in pregnant sheep was blocked by apocynin and tempol. In consistence with the myogenic responses, the hypoxia-mediated down-regulation of BKCa channel activity in uterine arteries of pregnant animals was reversed by apocynin. The findings suggest that heightened oxidative stress in uterine arteries plays a key role in suppressing the BKCa channel activity, resulting in increased myogenic reactivity and maladaptation of uteroplacental circulation caused by chronic hypoxia during gestation.

    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.

    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

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

    PAX8 is a useful immunohistochemical marker for the diagnosis of gynecologic tract malignancies. Several studies have described PAX8 expression in a wide variety of epithelial neoplasms, including ovarian and endometrial carcinomas. The goal of this study was to evaluate PAX8 expression in various types of uterine adenocarcinomas and mesonephric proliferations. Ninety-four cases of uterine adenocarcinomas (52 endometrial endometrioid carcinomas, 21 endometrial serous carcinomas, and 21 human papillomavirus-related endocervical carcinomas), 11 cases of benign mesonephric proliferations (remnants/hyperplasia), and normal endometrial and endocervical glandular epithelium in 58 cases were studied. Immunohistochemical staining was performed with the rabbit polyclonal anti-PAX8 antibody. All adenocarcinoma groups demonstrated a high frequency of PAX8 expression but with relatively high variability in the extent of staining among different subtypes. Both serous carcinomas and endometrioid carcinomas were positive in most cases (95% and 96%, respectively), but serous carcinomas displayed a significantly higher level of expression (immunohistochemical composite scores based on combined extent and intensity of expression) compared with endometrioid carcinomas (mean immunohistochemical composite scores: 8.3 vs. 5.3, respectively; Pglandular epithelia, normal endocervical glands exhibited a significantly lower level of expression compared with either normal endometrial glands or benign mesonephric proliferations (mean immunohistochemical composite scores: 2.6 vs. 6.6-11.2, respectively; P<0.0006). We conclude that PAX8 is expressed in the vast majority of uterine adenocarcinomas, including those of both endometrial and endocervical origin, and that the level of expression based on combined extent and intensity is highest in endometrial serous carcinoma and lowest in endocervical adenocarcinoma. However, the high prevalence of PAX8 expression in the various types of uterine

    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

    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. PMID:26222498

    Ultrasonographic and magnetic resonance (MR) imaging examinations of 68 women with uterine fibroids were reviewed to determine whether MR imaging may alter the therapeutic approach based on ultrasonography alone before uterine embolization. Therapeutic decisions based on ultrasonography alone were compared to those obtained after MR imaging. Discordant findings between both examinations involved 51 women (75%), and 19 (28%) had their therapeutic approaches based on ultrasonography alone altered by MR imaging. Ultrasonography and MR imaging showed concordant findings in 17 women (25%) for whom no changes in therapeutic option were made. MR imaging alters the therapeutic approach based on ultrasonography alone in 28% of candidates for uterine artery embolization. PMID:23206612

  15. A compendium of canine normal tissue gene expression.

    Full Text Available BACKGROUND: Our understanding of disease is increasingly informed by changes in gene expression between normal and abnormal tissues. The release of the canine genome sequence in 2005 provided an opportunity to better understand human health and disease using the dog as clinically relevant model. Accordingly, we now present the first genome-wide, canine normal tissue gene expression compendium with corresponding human cross-species analysis. METHODOLOGY/PRINCIPAL FINDINGS: The Affymetrix platform was utilized to catalogue gene expression signatures of 10 normal canine tissues including: liver, kidney, heart, lung, cerebrum, lymph node, spleen, jejunum, pancreas and skeletal muscle. The quality of the database was assessed in several ways. Organ defining gene sets were identified for each tissue and functional enrichment analysis revealed themes consistent with known physio-anatomic functions for each organ. In addition, a comparison of orthologous gene expression between matched canine and human normal tissues uncovered remarkable similarity. To demonstrate the utility of this dataset, novel canine gene annotations were established based on comparative analysis of dog and human tissue selective gene expression and manual curation of canine probeset mapping. Public access, using infrastructure identical to that currently in use for human normal tissues, has been established and allows for additional comparisons across species. CONCLUSIONS/SIGNIFICANCE: These data advance our understanding of the canine genome through a comprehensive analysis of gene expression in a diverse set of tissues, contributing to improved functional annotation that has been lacking. Importantly, it will be used to inform future studies of disease in the dog as a model for human translational research and provides a novel resource to the community at large.

    We investigated canine teams (dogs and their handlers) on Guam as a potential tool for finding invasive brown treesnakes (Boiga irregularis) in the wild. Canine teams searched a 40 ?? 40 m forested area for a snake that had consumed a dead mouse containing a radio-transmitter. To avoid tainting the target or target area with human scent, no snake was handled or closely approached prior to searches. Trials were conducted during the morning when these nocturnal snakes were usually hidden in refugia. A radiotracker knew the snake's location, but dog handlers and search navigators did not. Of 85 trials conducted over four months, the two canine teams had an average success rate of 35% of correctly defining an area ??? 5 ?? 5 m that contained the transmittered snake; the team with more experience prior to the trials had a success rate of 44% compared with 26% for the less experienced team. Canine teams also found 11 shed skins from wild snakes. Although dogs alerted outside the vicinity of transmittered snakes, only one wild, non-transmittered snake was found during the trials, possibly reflecting the difficulty humans have in locating non-transmittered brown treesnakes in refugia. We evaluated success at finding snakes as a function of canine team, number of prior trials (i.e. experience gained during the trials), recent canine success at finding a target snake, various environmental conditions, snake perch height, and snake characteristics (snout-vent length and sex). Success rate increased over the course of the trials. Canine team success also increased with increasing average humidity and decreased with increasing average wind speed. Our results suggest dogs could be useful at detecting brown treesnakes in refugia, particularly when compared to daytime visual searches by humans, but techniques are needed to help humans find and extract snakes once a dog has alerted. ??

    Natural killer (NK) cells play critical roles in induction of antiviral effects against various viruses of humans and animals. However, few data on NK cell activities during canine distemper virus (CDV) infections are available. Recently, we established a culture system allowing activation and expansion of canine non-B, non-T, large granular NK lymphocytes from PBMCs of normal dogs. In the present study, we explored the ability of such expanded NK cells to inhibit CDV infection in vitro. Cultured CD3-CD5-CD21- NK cells produced large amounts of IFN-γ, exhibited highly upregulated expression of mRNAs encoding NK-cell-associated receptors, and demonstrated strong natural killing activity against canine tumor cells. Although the expanded NK cells were dose-dependently cytotoxic to both normal and CDV-infected Vero cells, CDV infection rendered Vero cells more susceptible to NK cells. Pretreatment with anti-CDV serum from hyperimmunized dogs enhanced the antibody-dependent cellular cytotoxicity (ADCC) of NK cells against CDV-infected Vero cells. The culture supernatants of NK cells, added before or after infection, dose-dependently inhibited both CDV replication and development of CDV-induced cytopathic effects (CPEs) in Vero cells. Anti-IFN-γ antibody neutralized the inhibitory effects of NK cell culture supernatants on CDV replication and CPE induction in Vero cells. Such results emphasize the potential significance of NK cells in controlling CDV infection, and indicate that NK cells may play roles both during CDV infection and in combating such infections, under certain conditions.

    Conclusions: TVS is the primary investigative method for evaluating every infertile couple by means of uterine cavity and ovaries. Hysteroscopy is superior to SIS in diagnosis of intracavitatory abnormalities. However SIS has the advantage of being noninvasive, cheap, affordable, short duration and accurate method for uterine cavity evaluation.

    Full Text Available A total number of 12 postpartum (pp Nubian goats were included in the study to measure the uterine involution by ultrasonography from day 3 to 31 pp. Coinciding with ultrasonography, blood samples were collected at every 3 days to monitor the ovarian activity by measuring plasma progesterone (P4 concentration using progesterone radio-immuno-assay (RIA. Uterine diameter (UD and uterine lumen (UL were maximum on day 3, and minimum on day 31 pp. More than 50% of uterine involution occurred between day 3 and day 14 pp. The end of uterine involution was characterized by small UD and absence of lochia in the UL. The maximum (0.87±0.4 ng/mL and minimum (0.54±0.2 ng/mL plasma P4 levels were reported on day 27 and day 7 pp, respectively. Completion of uterine involution was recorded at 22±3.3 days pp. There was a negative correlation between P4 level and uterine parameters (UD and UL. It can be concluded that ultrasonography is a reliable tool to determine uterine involution in Nubian goats.

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

    2014-12-01

    Detection of low-level bed bug, Cimex lectularius L. (Hemiptera: Cimicidae), infestations is essential for early intervention, confirming eradication of infestations, and reducing the spread of bed bugs. Despite the importance of detection, few effective tools and methods exist for detecting low numbers of bed bugs. Scent dogs were developed as a tool for detecting bed bugs in recent years. However, there are no data demonstrating the reliability of trained canines under natural field conditions. We evaluated the accuracy of 11 canine detection teams in naturally infested apartments. All handlers believed their dogs could detect infestations at a very high rate (≥95%). In three separate experiments, the mean (min, max) detection rate was 44 (10-100)% and mean false-positive rate was 15 (0-57)%. The false-positive rate was positively correlated with the detection rate. The probability of a bed bug infestation being detected by trained canines was not associated with the level of bed bug infestations. Four canine detection teams evaluated on multiple days were inconsistent in their ability to detect bed bugs and exhibited significant variance in accuracy of detection between inspections on different days. There was no significant relationship between the team's experience or certification status of teams and the detection rates. These data suggest that more research is needed to understand factors affecting the accuracy of canine teams for bed bug detection in naturally infested apartments. PMID:26470083

    Uterine transplantation surgery has been proposed as a treatment for permanent absolute uterine factor infertility (AUFI) in the case of loss of the uterus. Due to the complexity of the vasculature correct reanastomosis of the blood supply during transplantation surgery is a crucial step to ensure reperfusion and viability of the organ. While techniques such as fluorescent dye imaging have been proposed to visualise perfusion there is no gold standard for intraoperative visualisation of tissue oxygenation. In this paper results from a liquid crystal tuneable filter (LCTF)-based multispectral imaging (MSI) laparoscope are described. The system was used to monitor uterine oxygen saturation (SaO2) before and after transplantation. Results from surgeries on two animal models (rabbits and sheep) are presented. A feature-based registration algorithm was used to correct for misalignment induced by breathing or peristalsis in the tissues of interest prior to analysis. An absorption spectrum was calculated at each spatial pixel location using reflectance data from a reference standard, and the relative contributions from oxy- and deoxyhaemoglobin were calculated using a least squares regression algorithm with non-negativity constraints. Results acquired during animal surgeries show that cornual oxygenation changes are consistent with those observed in point measurements taken using a pulse oximeter, showing reduced SaO2 following reanastomosis. Values obtained using the MSI laparoscope were lower than those taken with the pulse oximeter, which may be due to the latter's use of the pulsatile arterial blood signal. Future work incorporating immunological test results will help to correlate SaO2 levels with surgical outcomes.

  15. Uterine Artery Embolization for Ureteric Obstruction Secondary to Fibroids

    International Nuclear Information System (INIS)

    This case series examines the safety and efficacy of uterine artery embolization (UAE) in the treatment of obstructive nephropathy caused by large fibroids. Between 2004 and 2007, 10 patients referred with symptomatic uterine fibroids that were found to be causing either unilateral (7 patients) or bilateral (3 patients) hydronephrosis were treated by UAE. Presenting complaints included menorrhagia, dysmenorrhea, bulk symptoms, loin pain, postobstructive atrophy, and mild renal impairment. All had posterior intramural dominant fibroids >11 cm in maximum sagittal diameter and uterine volumes between 3776 and 15,625 ml. Outcome measures at between 12 and 36 months included procedural success, repeat intervention, relief of symptoms, resolution of hydronephrosis, stable renal function and size, and avoidance of hysterectomy. In all cases the cause of renal obstruction was confirmed to be a giant fibroid compressing the ureter at the pelvic brim. In all cases UAE was technically successful, though two patients required a repeat procedure. In eight patients hydronephrosis resolved and the obstruction was relieved, though two still had some bulk symptoms not requiring further treatment. Renal function improved or was stable in all cases. Renal size was stable in all cases. Where menorrhagia was part of the symptom complex it was relieved in all cases. Two patients diagnosed as having postobstructive atrophy of one kidney underwent retrograde ureteric stenting on the nonatrophied side prior to UAE. This was unsuccessful in one of the cases due to the distortion caused by the fibroid. Despite improvement in hydronephrosis this patient underwent hysterectomy at 7 months after a renogram demonstrated persistent obstruction at the pelvic brim. In the second patient a double pigtail stent was inserted with difficulty and eventually removed at 8 months. This patient has had stable renal function and size for 3 years post-UAE. We conclude that UAE is safe and effective in

    Full Text Available This paper aims to describe the uterine and ovarian ultrasonographic characteristics and Doppler velocimetric features of their arteries in bitches during the periovulatory period. Fifteen estrous cycles in 10 animals were evaluated. The ultrasonographic characteristics, resistance indices (RI and pulsatility indices (PI of the uterus and ovaries in each animal were recorded 5 days before and after ovulation (D0. The data were statistically analyzed, and the results were expressed as the mean ± standard error of mean (P<0.05. In results the ultrasonographic features of the uterus were the same on all of the cycles and evaluated days. The uterus had an average diameter of 0.85±0.02cm. An increase in the volume of the ovaries and the diameter of the ovarian follicles were measured. Ovaries had a volume of 0.64±0.06cm³, and the follicles cavities had a diameter of 0.46 ± 0.01 cm on the day of ovulation. After ovulation, it was observed that some follicles not collapse in some cycles. Two days prior to ovulation, the uterine blood perfusion decreased. This decrease remained unchanged until ovulation. Following ovulation, we measured a gradual increase in the uterine perfusion and in the ovarian artery. This artery directed blood flow to the ovaries and increased the intra-ovarian perfusion on the day after ovulation. In conclusion, specific features are observed in the uterus and ovarian ultrasound image and Doppler values of their arteries presented on the periovulatory days and when associated allow to estimate more accurately the date of ovulation.

    Helena Isabel Lopes

    2015-01-01

    Full Text Available Background. Several pregnancies have been reported after embolization of uterine artery. This procedure is an accepted nonsurgical treatment for symptomatic uterine fibroids but its safety in women desiring future childbearing is not well established. Case Report. We present a 40-year-old woman with leiomyomata who became pregnant after previously undergone uterine artery embolization for three times. The placenta was previa and the fetus was in transverse position. She had a cesarean delivery of an appropriately grown fetus at 37 weeks, which was followed by uterine atony requiring hysterectomy. Conclusion. Although pregnancy-related outcomes remain understudied, the available reports evidence that pregnancies after uterine artery embolization may be at significantly increased risk for postpartum hemorrhage, cesarean delivery, abnormal placentation, and malpresentation. In patients who are undergoing this type of treatment and contemplating pregnancy, the possibility of adverse complications should be taken in consideration and women should be appropriately advised.

  20. Superselective uterine artery embolization for the control and prevention of obstetric hemorrhage

    International Nuclear Information System (INIS)

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

    Objective To discuss the diagnosis of and conservative management for lower uterine segment pregnancy with placenta increta complicating first trimester abortion. Methods Four patients with previous caesarean section and severe hemorrhage in induced abortion during the first trimester were studied. Uterine artery embolization (UAE) was used to control bleeding and preserve the uterus. Results UAE controlled heavy uterine bleeding satisfactorily. One of the four patients asked for a hysterectomy after UAE, and her pathology report confirmed "lower uterine segment pregnancy with placenta increta". Conclusion Previous caesarean section is a risk factor for lower uterine segment pregnancy with placenta increta. UAE is one of the best conservative management methods for heavy hemorrhage, especially for women who desire future fertility.

    In radiotherapy the treatment outcome of gynecological (GYN) cancer patients is crucially related to reproducibility of the actual uterine position. The purpose of this study is to evaluate the inter-operator variability in addressing uterine position using a novel 3-D ultrasound (US) system...... significantly larger inter-fractional uterine positional displacement, in some cases up to 20 mm, which outweighs the magnitude of current inter-operator variations. Thus, the current US-phantom-study suggests that the inter-operator variability in addressing uterine position is clinically irrelevant........ The study is initiated by US-scanning of a uterine phantom (CIRS 404, Universal Medical, Norwood, USA) by seven experienced US operators. The phantom represents a female pelvic region, containing a uterus, bladder and rectal landmarks readily definable in the acquired US-scans. The organs are subjected...

Abdominal ultrasonography revealed minimum enlargement of the right uterine horn filled with anechoic fluid. On excretory urography, functionally and anatomically normal, enlarged left kidney was found, but right kidney was absent. It was preliminary diagnosed as hydrometra with right renal agenesis. Aiming at the correction of hydrometra, we performed ovariohysterectomy. During spaying, we found a missing segment of distal part of the right uterine horn and absence of ipsilateral kidney and ureter. Compressed uterine structure and segmental aplasia of right uterine horn were found in histopathological investigation. Taken together, it was diagnosed as a segmental aplasia of uterine horn with ipsilateral renal agenesis. PMID:18628611

    A 5-yr-old female African hedgehog (Ateleris albiventris) presented with hematuria. Vulvar culture results revealed a 4+ growth of Enterococcus sp. and gamma-Streptococcus sp. susceptible to trimethoprim sulfa and enrofloxacin. Ultrasound evaluation of the abdomen revealed an unidentifiable tubular structure in the region of the reproductive tract. An exploratory laparotomy and ovariohysterectomy were performed. Pathologic studies of the uterus showed a uterine spindle cell tumor, uterine endometrial polyp, uterine adenomyosis, and a possible acute infarct resulting in uterine wall necrosis. Hematuria did not reoccur, and the hedgehog lived for another 19 mo until she died from an oral squamous cell carcinoma. To date, this is the first report of a uterine spindle cell tumor in an African hedgehog. PMID:18229871

    2015-01-01

    Canine parvovirus (CPV) infection is one of the most important and common infectious diseases in dogs, in particular affecting young puppies when maternal antibodies have waned and vaccine-induced antibodies have not yet developed. The mortality rate remains high. Therefore, a rapid and safe diagnostic tool is essential to diagnose the disease to 1) provide intensive care treatment and 2) to identify virus-shedding animals and thus prevent virus spread. Whilst the detection of antibodies against CPV is considered unsuitable to diagnose the disease, there are several different methods to directly detect complete virus, virus antigen or DNA. Additionally, to test in commercial laboratories, rapid in-house tests based on ELISA are available worldwide. The specificity of the ELISA rapid in-house tests is reported to be excellent. However, results on sensitivity vary and high numbers of false-negative results are commonly reported, which potentially leads to misdiagnosis. Polymerase chain reaction (PCR) is a very sensitive and specific diagnostic tool. It also provides the opportunity to differentiate vaccine strains from natural infection when sequencing is performed after PCR.

The dog was presented with a history of ptyalism, halitosis, local pain, decreased appetite, and blood staining noted on food and water bowls. Clinical, hematologic, and biochemical examinations, abdominal ultrasonography, and 3-view chest radiographs were performed, and no metastases were found. Histopathologic examination of two 6 mm punch biopsies from the oral lesion revealed the presence of eosinophilic granulomatous lesions in the submucosa. After treatment with corticosteroids and wide spectrum antibiotics no significant changes in clinical signs and lesion size were observed. Electrochemotherapy (ECT, a novel tumor treatment routinely used for cutaneous and subcutaneous tumors in human patients in the European Union since 2006, was used to treat the eosinophilic granuloma. The procedure was performed under general anesthesia, followed by intravenous administration of bleomycin. Six weeks after treatment a complete response with disappearance of the mass and improvement of clinical signs were observed.

    Dogs are capable of detecting and discriminating a number of compounds constituting a complex odor. However, they use only a few of these to recognize a substance. The focus of this research is to determine the compounds dogs learn to use in recognizing explosives. This is accomplished by training dogs under behavioral laboratory conditions to respond differentially on separate levers to 1) blank air, 2) a target odor, such as an explosive, and 3) all other odors (non-target odors). Vapor samples are generated by a serial dilution vapor generator whose operation and output is characterized by GC/MS. Once dogs learn this three-lever discrimination, testing sessions are conducted containing a number of probe trials in which vapor from constituent compounds of the target is presented. Which lever the dogs respond to on these probe trials indicates whether they can smell the compound at all (blank lever) or whether it smells like toe target odor (e.g., the explosive) or like something else. This method was conducted using TNT, C-4, and commercial dynamite. The data show the dogs' reactions to each of the constituent compounds tested for each explosive. Analysis of these data reveal the canine detection odor signature for these explosives.

    In humans, high-grade gliomas may infiltrate across the corpus callosum resulting in bihemispheric lesions that may have symmetrical, winged-like appearances. This particular tumor manifestation has been coined a “butterfly” glioma (BG). While canine and human gliomas share many neuroradiological and pathological features, the BG morphology has not been previously reported in dogs. Here, we describe the magnetic resonance imaging (MRI) characteristics of BG in three dogs and review the potential differential diagnoses based on neuroimaging findings. All dogs presented for generalized seizures and interictal neurological deficits referable to multifocal or diffuse forebrain disease. MRI examinations revealed asymmetrical (2/3) or symmetrical (1/3), bihemispheric intra-axial mass lesions that predominantly affected the frontoparietal lobes that were associated with extensive perilesional edema, and involvement of the corpus callosum. The masses displayed heterogeneous T1, T2, and fluid-attenuated inversion recovery signal intensities, variable contrast enhancement (2/3), and mass effect. All tumors demonstrated classical histopathological features of glioblastoma multiforme (GBM), including glial cell pseudopalisading, serpentine necrosis, microvascular proliferation as well as invasion of the corpus callosum by neoplastic astrocytes. Although rare, GBM should be considered a differential diagnosis in dogs with an MRI evidence of asymmetric or symmetric bilateral, intra-axial cerebral mass lesions with signal characteristics compatible with glioma.

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

    Full Text Available Abstract Background Chromosomal translocations affecting the chromosome 2p21 cluster in a 450 kb breakpoint region are frequently observed in human benign thyroid adenomas. THADA (thyroid adenoma associated was identified as the affected gene within this breakpoint region. In contrast to man tumours of the thyroid gland of dogs (Canis lupus familiaris constitute mainly as follicular cell carcinomas, with malignant thyroid tumours being more frequent than benign thyroid adenomas. In order to elucidate if the THADA gene is also a target of chromosomal rearrangements in thyroid adenomas of the dog we have physically mapped the canine THADA gene to canine chromosome 10. A PCR was established to screen a canine genome library for a BAC clone containing the gene sequence of canine THADA. Further PCR reactions were done using the identified BAC clone as a template in order to verify the corresponding PCR product by sequencing. Canine whole blood was incubated with colcemid in order to arrest the cultured cells in metaphases. The verified BAC DNA was digoxigenin labeled and used as a probe in fluorescence in situ hybridization (FISH. Ten well spread metaphases were examined indicating a signal on canine chromosome 10 on both chromatids. A detailed fine mapping was performed indicating the canine THADA gene locus on the q-arm of chromosome 10. Results The canine THADA gene locus was mapped on chromosome 10q25. Our mapping results obtained in this study following the previously described nomenclature for the canine karyotype. Conclusion We analysed whether the THADA gene locus is a hotspot of canine chromosomal rearrangements in canine neoplastic lesions of the thyroid and in addition might play a role as a candidate gene for a possible malignant transformation of canine thyroid adenomas. Although the available cytogenetic data of canine thyroid adenomas are still insufficient the chromosomal region to which the canine THADA has been mapped seems to be no

    Full Text Available Objective: The aims of this study were to compare different surgical approaches to rapid canine retraction by designing and selecting the most effective method of reducing resistance by a three-dimensional finite element analysis. Material and Methods: Three-dimensional finite element models of different approaches to rapid canine retraction by reducing resistance and distraction were established, including maxillary teeth, periodontal ligament, and alveolar. The models were designed to dissect the periodontal ligament, root, and alveolar separately. A 1.5 N force vector was loaded bilaterally to the center of the crown between first molar and canine, to retract the canine distally. The value of total deformation was used to assess the initial displacement of the canine and molar at the beginning of force loading. Stress intensity and force distribution were analyzed and evaluated by Ansys 13.0 through comparison of equivalent (von Mises stress and maximum shear stress. Results: The maximum value of total deformation with the three kinds of models occurred in the distal part of the canine crown and gradually reduced from the crown to the apex of the canine; compared with the canines in model 3 and model 1, the canine in model 2 had the maximum value of displacement, up to 1.9812 mm. The lowest equivalent (von Mises stress and the lowest maximum shear stress were concentrated mainly on the distal side of the canine root in model 2. The distribution of equivalent (von Mises stress and maximum shear stress on the PDL of the canine in the three models was highly concentrated on the distal edge of the canine cervix. . Conclusions: Removal of the bone in the pathway of canine retraction results in low stress intensity for canine movement. Periodontal distraction aided by surgical undermining of the interseptal bone would reduce resistance and effectively accelerate the speed of canine retraction.

    In the uterus of the mare, data obtained using transrectal Doppler ultrasonography indicate that uterine blood flow (UBF) is dynamic and changes throughout the estrous cycle. Degenerative lesions in the uterus are associated with subfertility and infertility. Among these lesions, vascular elastosis has been reported in aged, multiparous, and infertile mares. Angiosis of the uterine vasculature could potentially compromise UBF. The objectives of this experiment are to determine levels of UBF and perfusion of reproductively healthy mares and compare them to levels of subfertile/infertile mares affected by uterine vascular elastosis. Twenty mares were classified on the basis of degree of vascular degeneration and stage of cycle. A fluorescent microsphere technique was used to measure reproductive organ perfusion, where microspheres were injected into the left ventricle of the heart and became trapped in capillary beds in proportion to blood flow and tissue perfusion. The reproductive tract was removed, sectioned, and the fluorescent intensity evaluated to measure blood flow and perfusion. Additionally, full-thickness samples of the uterine wall were examined postmortem to further assess the degree of vascular degeneration in all layers of uterine wall. The mean value of uterine perfusion for the control mares during estrus (n = 5) was higher (P perfusion was not different (P > 0.05) during estrus (n = 5) and diestrus (n = 5); 5.9 and 7.2 mL/min/100g, respectively. Uterine perfusion in subfertile/infertile mares affected by elastosis was lower than that of control mares during both estrus (P perfusion between the control and elastosis groups indicate that elastosis of the uterine vasculature is associated with decreased uterine perfusion during both phases of the estrous cycle. In the uterus, a compromise in UBF could have implications in endometrial glandular development, postbreeding endometritis, uterine clearance, development of the conceptus, and

    2012-01-01

    Full Text Available Canine distemper is a highly contagious viral disease caused by the canine distemper virus (CDV, which is a member of the Morbillivirus genus, Paramyxoviridae family. Animals that most commonly suffer from this disease belong to the Canidae family; however, the spectrum of natural hosts for CDV also includes several other families of the order Carnivora. The infectious disease presents worldwide distribution and maintains a high incidence and high levels of lethality, despite the availability of effective vaccines, and no specific treatment. CDV infection in dogs is characterized by the presentation of systemic and/or neurological courses, and viral persistence in some organs, including the central nervous system (CNS and lymphoid tissues. An elucidation of the pathogenic mechanisms involved in canine distemper disease will lead to a better understanding of the injuries and clinical manifestations caused by CDV. Ultimately, further insight about this disease will enable the improvement of diagnostic methods as well as therapeutic studies.

    Full Text Available A new human coronavirus responsible for severe acute respiratory syndrome (SARS was identified in 2003, which raised concern about coronaviruses as agents of serious infectious disease. Nevertheless, coronaviruses have been known for about 50 years to be major agents of respiratory, enteric, or systemic infections of domestic and companion animals. Feline and canine coronaviruses are widespread among dog and cat populations, sometimes leading to the fatal diseases known as feline infectious peritonitis (FIP and pantropic canine coronavirus infection in cats and dogs, respectively. In this paper, different aspects of the genetics, host cell tropism, and pathogenesis of the feline and canine coronaviruses (FCoV and CCoV will be discussed, with a view to illustrating how study of FCoVs and CCoVs can improve our general understanding of the pathobiology of coronaviruses.

    Canine dysautonomia is a sporadic, generally fatal disease that rarely affects groups of related animals. Four 10-week-old Havanese puppies from a litter of 5 developed clinical signs of canine dysautonomia. The 4 affected dogs were exposed to an outdoor environment, whereas the fifth littermate was not exposed to the outdoors and remained clinically healthy. Clinical signs of dysautonomia developed 10-16 days after going outside the house. An unrelated dog also developed dysautonomia after exposure to 1 of the affected Havanese littermates. All 5 dogs had morphological changes consistent with dysautonomia (widespread neuronal degeneration in autonomic ganglia, select brainstem nuclei, and ventral horn motor neurons). Differential diagnoses were excluded through negative toxicological evaluation, fecal parasite screening, negative Canine distemper virus reverse transcription polymerase chain reaction, fluorescent antibody testing, attempted virus isolation, and electron microscopy. The 5 affected dogs were in the Kansas City, Missouri area, where there is a high incidence of dysautonomia. PMID:26179098

    There is strong evidence indicating that the pancreas is under the influence of sex steroid hormones, and that it may even participate in their biosynthesis and metabolism. In the present study, (3H)testosterone was perfused into the isolated canine pancreas, and measured in the effluent with several of its metabolites (5 alpha-dihydrotestosterone, androstenedione, and estradiol). Results show that testosterone is readily transformed by the canine pancreas. The main product found in the effluent is androstenedione. The testis and spleen were also perfused with (3H)testosterone and used as controls. In both cases, this hormone appeared mostly unchanged in the effluent as compared to the pancreatic perfusion (p less than 0.0001). From our data, we conclude that the canine pancreas has the capacity to transform sex steroid hormones, and could be considered an extragonadal site of sex steroid biosynthesis.

    The distribution of amyloid-beta protein (A beta) in the canine brain was demonstrated by immunochemistry on serially sectioned tissues from 10 aged mixed breed dogs. Summation of quantitative data and relegation to anatomical sites for the 10 dogs showed A beta to be widely distributed in the cortex and hippocampus while completely absent in the brain stem and cerebellum. The highest density of A beta was in the dentate gyrus of the hippocampus. Cortical areas exhibiting the greatest A beta deposition were the posterior and medial suprasylvius gyrus and the proreus gyrus of the frontal lobe. Unlike humans the canine entorhinal cortex, amygdala, basal ganglia and olfactory bulbs were rarely affected. This suggested that the highly developed olfactory pathways of the canine are generally spared from A beta deposition. PMID:9141082

    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. PMID:27543040

    Full Text Available A 13-year-old female patient reported with the chief complaint of irregular front teeth. She had a skeletal Class III and Angle′s Class I malocclusion with hyperdivergent growth pattern and bilateral impaction of maxillary canines. Surgical exposure of the impacted teeth and orthodontic alignment was planned. The surgical exposure was done by a minimally invasive modified window technique. Orthodontic treatment of impacted canines without causing significant morbidity to the adjacent teeth and periodontium is a challenge. The bilaterally impacted maxillary canines were successfully aligned and leveled. The depth of the gingival sulcus and clinical crown heights of disimpacted teeth were normal post-treatment and after 1 year of retention.

    Full Text Available Introduction: Odontomas are malformations of the dental tissues and may interfere with the eruption of the associated tooth. The early diagnosis, followed by a proper treatment at the right time, will result in a favorable prognosis and a desirable occlusion development. Complex odontomas associated to primary teeth are rare. Case report and conclusion: This article describes a case of a complex odontoma in a four-year-old girl that prevented eruption of the left primary canine. The treatment choice was enucleation of the odontoma and the maintenance of the left primary canine.In this case, complete removal of the complex odontoma was successfully conducted, since after one year of follow-up the primary maxillary canine restarted its eruption process.

    Canine platelets have been extensively studied but little is known about specific aspects such as adhesion. Platelet adhesion is a critical step during haemostasis and thrombosis as well as during inflammatory and immunopathogenic responses. The aim of this study was to evaluate the adhesive properties of canine platelets using fibrinogen and collagen as substrates immobilized on plates. Adhesion was monitored for 120 min and the effect of adenosine 5'-diphosphate (ADP) was assayed. The results showed that canine platelets displayed good adhesion activity that was significantly time-dependent. Moreover, ADP was able to enhance platelet adhesion in a dose-dependent manner. The findings aid knowledge of the adhesion process and suggest a specific role of surface platelet receptors in mediating the interaction with extracellular matrix proteins.

    Full Text Available Canine impaction is a dental problem very often encountered in orthodontic practice. After the third molar, the canine is the most frequently impacted tooth. Bringing the impacted canine into a normal position is important for functional occlusion and the final esthetics of the orthodontic treatment. This article illustrates a peculiar case, in which all four permanent canines maintained their unerupted status at age of 16 years. All four impacted canines were surgically exposed, attachment bonded, traction given with K-9 spring and ideally positioned with fixed orthodontic mechanotherapy.

  10. Recombinant antigens from Phlebotomus perniciosus saliva as markers of canine exposure to visceral leishmaniases vector.

    Directory of Open Access Journals (Sweden)

    Jan Drahota

    Full Text Available BACKGROUND: Phlebotomus perniciosus is the main vector in the western Mediterranean area of the protozoan parasite Leishmania infantum, the causative agent of canine and human visceral leishmaniases. Infected dogs serve as a reservoir of the disease, and therefore measuring the exposure of dogs to sand fly bites is important for estimating the risk of L. infantum transmission. In bitten hosts, sand fly saliva elicits a specific antibody response that reflects the intensity of sand fly exposure. As screening of specific anti-saliva antibodies is limited by the availability of salivary gland homogenates, utilization of recombinant salivary proteins is a promising alternative. In this manuscript we show for the first time the use of recombinant salivary proteins as a functional tool for detecting P. perniciosus bites in dogs. METHODOLOGY/PRINCIPAL FINDINGS: The reactivity of six bacterially-expressed recombinant salivary proteins of P. perniciosus, yellow-related protein rSP03B, apyrases rSP01B and rSP01, antigen 5-related rSP07, ParSP25-like protein rSP08 and D7-related protein rSP04, were tested with sera of mice and dogs experimentally bitten by this sand fly using immunoblots and ELISA. In the immunoblots, both mice and canine sera gave positive reactions with yellow-related protein, both apyrases and ParSP25-like protein. A similar reaction for recombinant salivary proteins was observed by ELISA, with the reactivity of yellow-related protein and apyrases significantly correlated with the antibody response of mice and dogs against the whole salivary gland homogenate. CONCLUSIONS/SIGNIFICANCE: Three recombinant salivary antigens of P. perniciosus, yellow-related protein rSP03B and the apyrases rSP01B and rSP01, were identified as the best candidates for evaluating the exposure of mice and dogs to P. perniciosus bites. Utilization of these proteins, or their combination, would be beneficial for screening canine sera in endemic areas of visceral

    Full text: The objective of this study was to evaluate the levels of trace elements in blood sera of uterine cervix cancer patients, analyze their alteration with respect to healthy controls, ascertain the role played by them in the initiation, promotion and inhibition of cancer, and identify the best predictors amongst these for disease occurrence and progression. Moreover, the variation of trace elemental content in the sera of cervix cancer patients with the clinical stage of disease and with therapy was also studied. Particle induced X-ray emission (PIXE), a well established method for elemental analysis, was used in this work to identify and quantify trace elements in the blood sera of uterine cervix cancer subjects and healthy control subjects. The PIXE measurements were carried out using 2.5 MeV collimated proton beam from the 3 MV Tandem Pelletron Accelerator at lon Beam Laboratory, Institute of Physics, Bhubaneswar, India. Among all the trace elements identified in this work, statistically significant alterations in serum levels of copper, zinc, and selenium were observed among the various studied groups. The observed alterations are discussed with respect to the possible mechanisms by which these elements might influence the carcinogenic process. (author)

  12. The MRI diagnosis of extra-uterine pregnancy

    International Nuclear Information System (INIS)

    Objective: It's an investigation of the finding and diagnostic value of MRI in extrauterine pregnancy. Methods: A retrospective analysis of the MR images and clinical data was made in 4 cases with extra-uterine pregnancy. All cases were confirmed by surgery and pathology. Results: All lesions were found in oviducts. Un-ruptured oviductal pregnancy represented a round hypo-intense area with a lower signaled center on T1WI, and a hyper-intense area on T2WI, while higher signal of the embryo sac wall was revealed on T2WI. In the rest 2 cases, ruptured ectopic pregnancy presented with a complicated intense mass on T1WI, where hyper-intense patches were scattered within lesion. On T2WI, the ruptured oviductal pregnancy was a mixture of iso-intense or hyper-intense components. On T2WI/IR fat suppressing sequence the hyper-intense area remained high signal intensity. A ruptured oviductal pregnancy resulted in a larger mass with hemorrhage found in pelvic cavity. Conclusion: Extra-uterine pregnancy has characteristic MRI manifestations, by which an accurate diagnosis is established with clinical data

    This review analyzes current pitfalls in pretreatment staging of endometrial and cervical carcinoma with magnetic resonance imaging (MRI) based on a critical review of the literature. Technical, patient, and tumor-related characteristics were analyzed to improve further staging of uterine neoplasm with MRI. For endometrial carcinoma staging, contrast-enhanced dynamic imaging appears essential to avoid false-positive findings for deep myometrial invasion by better delineating tumor from normal myometrium. However, leiomyomas, adenomyosis, and grade 3 tumors provide difficulties in staging for pathologists and radiologists. Slice orientation perpendicular to the long axis of the cervical channel might improve false-negative findings for deep stromal invasion on T2-weighted images in endometrial and cervical cancer. Contrast-enhanced sequences do not improve diagnosis of parametrial or vaginal invasion in cervical cancer. Assessment of lymph node invasion by any imaging modality has limited sensitivity in detecting lymph node metastasis smaller than 5 mm. Knowledge of diagnostic criteria is critical to avoid false-negative findings for bladder wall invasion. Higher spatial resolution with dedicated multichannel pelvic phase array coils, smaller fields of view and section thickness, and careful comparison of T2-weighted and contrast-enhanced sequences are strategies that might avoid misinterpretation of pelvic MRI in staging uterine neoplasm.

  14. Results of radiation therapy for carcinoma of the uterine cervix

    International Nuclear Information System (INIS)

    Fifty-nine consecutive patients who were treated with radiation therapy for carcinoma of the uterine cervix between April 1982 and December 1986 were reviewed. Twelve patients were treated with low dose-rate intracavitary irradiation using radium-226, and 46 were treated with high dose-rate irradiation using a remote afterloading system combined with external irradiation, and the other one was treated with external irradiation alone. The 5-year-survival rates for stage Ib, IIa, IIb, IIIb, and IVa were 77.8, 85.7, 87.5, 45.5 and 40.0%, respectively. The 5-year-survival rates for the low and high dose-rates irradiation were 66.7 and 73.9%, respectively. The most common complication of radiation therapy was rectal bleeding, which required conservative treatment (grade 2) in 11 (18.6%). The morbidities for the low and high dose-rates irradiation were similar. The causes of death in 17 patients were local recurrence in 14, metastases in 2 and other specified in one. These findings suggest that high dose-rate intracavitary irradiation is as effective as low dose-rate irradiation for carcinoma of the uterine cervix, and that further efforts for controlling the local tumors with stage IIIb disease without an increased rate of side-effects is required.

    Full Text Available Background: In molar pregnancy, when hydatidiform changes are local and some embryonic components are observed, the term of partial mole is used. The risk of persistent trophoblastic tumor after partial mole is much lower than complete mole. In this persistent cases almost all are non metastatic. The aim of this study is to report a case of uterine rupture following incomplete molar pregnancy.Case presentation: The patient was a 26 year old woman with obstetric history of an abortion and one molar pregnancy and no child. She was referred to emergency unit in Ghaem University Hospital, Mashhad, Iran in May 2011. She had an evacuation curettage following molar pregnancy three months before and without any follow up visit. The patient was referred to emergency unit with hemorrhagic shock. She immediately underwent laparotomy. The uterine fundal rupture was repaired and evacuation curettage performed. In post operative evaluation, she had a nine millimeter metastatic nodule in base of right Lung. As a patient in low risk stage III, she received weekly intramuscular methotrexate (40mg/m2 for six courses. In follow up visit -hCG titer was negative (<10miu/ml at 5th week. Conclusion: In cases of in complete molar pregnancy risk of metastasis is very low. Serial beta-hCG titer is the most accurate method for detection of persistent gestational trophoblastic disease (GTN. In neglected cases like this case preservation of ruptured uterus in GTN is possible.

    Objective:To investigate the role of epidermal growth factor (EGF) in the pathogenesis of uterine leiomyomas.Methods: Human myometrial smooth muscle cells (HM-SMCs) and smooth muscle cells of human uterine leiomyomas (HL-SMCs) were separated from patients’ specimens and cultured. After processed by EGF or PD98059 (inhibitor of MKK/MEK) +EGF, the proliferation rate of both SMCs was detected by BrdU method and the phosphorylation level of p44/42 mitogen-activated protein kinase (MAPK) was determined by Western-blot. After different processing time by EGF, the phosphorylation levels of p44/42 MAPK and AKT and p27 expression level in both SMCs were detected by Western-blot.Results: EGF could significantly promote HL-SMCs proliferation and PD98059 could inhibit this effect (P<0.05); besides, PD98059 could inhibit the increase of the phosphorylation level of p44/42 MAPK in both SMCs induced by EGF. When the processing time by EGF was over 15min, the phosphorylation levels of p44/42 MAPK and AKT in both SMCs decreased sharply and were close to zero; p27 expression in HM-SMCs raised significantly while the upregulation in HL-SMCs was little.Conclusions: EGF could not cause activation of EGFR because of the dephosphorylation of p44/42 MAPK and AKT in HL-SMCs, which caused p27 expression insufficiently and cell cycle dysregulation.

    Full Text Available Objective. Postpartum hemorrhage (PPH is an important cause of maternal mortality (MM around the world. Seventy percent of the PPH corresponds to uterine atony. The objective of our study was to evaluate multicenter PPH cases during a 10-month period, and evaluate severe postpartum hemorrhage management. Study Design. The study population is a cohort of vaginal delivery and cesarean section patients with severe postpartum hemorrhage secondary to uterine atony. The study was designed as a descriptive, prospective, longitudinal, and multicenter study, during 10 months in 13 teaching hospitals. Results. Total live births during the study period were 124,019 with 218 patients (0.17% with severe postpartum hemorrhage (SPHH. Total maternal deaths were 8, for mortality rate of 3.6% and a MM rate of 6.45/100,000 live births (LB. Maternal deaths were associated with inadequate transfusion therapy. Conclusions. In all patients with severe hemorrhage and subsequent hypovolemic shock, the most important therapy is intravascular volume resuscitation, to reduce the possibility of target organ damage and death. Similarly, the current proposals of transfusion therapy in severe or massive hemorrhage point to early transfusion of blood products and use of fresh frozen plasma, in addition to packed red blood cells, to prevent maternal deaths.

    Full Text Available A 42-year-old woman, gravida 3, para 3 was admitted to hospital because of painful oedema of her right lower extremity. Initial physical examination revealed a gross, firm tumour filling the entire peritoneal cavity. Doppler ultrasound scan revealed a thrombus in the right common iliac vein, extending to the right femur and popliteal veins, and partially into the calf deep vein. Computed tomography confirmed the existence of an abdominal tumour probably deriving from the genital organs and the presence of a thrombus in the said veins.The patient underwent hysterectomy where a myomatous uterine was removed. She was put on subcutaneous enoxaparine and compressive therapy of the lower extremities. Such symptoms as pain and oedema receded. Control Doppler scan showed fibrinolysis, partial organization of the thrombus and final vein recanalisation. After exclusion of other risk factors of deep vein thrombosis apart from stasis, we conclude that the described pathology was the effect of compression of regional pelvic structures by a uterine myoma.

    Full Text Available The aim of this study was to examine the intra-uterine exposure to Sarcocystis spp. antigens, determining the number of foals with detectable concentrations of antibodies against these agents in the serum, before colostrum ingestion and collect data about exposure of horses to the parasite. Serum samples were collected from 195 thoroughbred mares and their newborns in two farms from southern Brazil. Parasite specific antibody responses to Sarcocystis antigens were detected using the indirect immunofluorescent antibody test (IFAT and immunoblot analysis. In 84.1% (159/189 of the pregnant mares and in 7.4% (14/189 of foals we detected antibodies anti-Sarcocystis spp. by IFAT. All samples seropositive from foals were also positive in their respective mares. Serum samples of seropositive foals by IFAT, showed no reactivity on the immunoblot, having as antigens S. neurona merozoites. In conclusion, the intra-uterine exposure to Sarcocystis spp. antigens in horses was demonstrated, with occurrence not only in mares, but also in their foals, before colostrum ingestion these occurrences were reduced.

    2011-11-01

    Canine distemper virus (CDV) causes a major disease of domestic dogs that develops as a serious systemic infection in unvaccinated or improperly vaccinated dogs. Domesticated dogs are the main reservoir of CDV, a multihost pathogen. This virus of the genus Morbillivirus in the family Paramyxoviridae occurs in other carnivorous species including all members of the Canidae and Mustelidae families and in some members of the Procyonidae, Hyaenidae, Ursidae, and Viverridae families. Canine distemper also has been reported in the Felidae family and marine mammals. The spread and incidences of CDV epidemics in dogs and wildlife here and worldwide are increasing. PMID:22041204

    Full Text Available Introduction. Full impaction of canines, in both jaws, is a rare phenomenon. It is usually coupled with the persistence of deciduous canines, or any other irregularity in the dental arch. Case report. Panoramic radiograph of a 24-year-old female patient showed bilateral canine impaction in both jaws. Due to vestibular, apical and medial position of canines in the upper jaw, the surgical approach implied the apically positioned flap technique. The position of impacted mandibular canines was vertical with more coronal position relative to the upper canines, thus requiring a closed eruption technique. Conclusion. Inadequate position of impacted canines in the bone fully justifies the use of orthodontic-surgical treatment.

    Full Text Available A genome-wide association study for canine hip dysplasia (CHD and canine elbow dysplasia (CED using the Illumina canine high density bead chip had been performed for 174 Bernese mountain dogs. General and mixed linear model analysis identified two different regions with single nucleotide polymorphisms (SNPs on dog chromosome (CFA 14 significantly associated with CHD and a further significantly CHD-associated region on CFA37. For CED, four SNPs on CFA11 and 27 were significantly associated. The identified SNPs of four associated regions included nearby candidate genes. These possible positional candidates were the genes PON2 on CFA14 and FN1 on CFA37 for CHD and the genes LMNB1 on CFA11 and WNT10B on CFA27 for CED.

An obvious target is bacterial adhesion. Bacterial adhesion to surfaces is the first step in colonization, invasion, and biofilm formation....... As such, adhesion represents the Achilles heel of crucial pathogenic functions. It follows that interference with adhesion can reduce bacterial virulence. Here, we illustrate this important topic with examples of techniques being developed that can inhibit bacterial adhesion. Some of these will become...

  7. Radiographic imaging of the canine intercondylar fossa

    International Nuclear Information System (INIS)

    The intercondylar fossa is believed to play an important role in the pathology of cranial cruciate ligament rupture and therefore has received considerable attention in the last decade. Accurate radiographic imaging of the intercondylar fossa requires that the central x-ray beam pass through the center of the intercondylar “tunnel”. The anatomy of the canine intercondylar fossa is similar to humans, however, the orientations of the intercondylar fossa's differ. Consequently, the positioning techniques described for humans are not appropriate for the dog. To pass through the center of the dog, intercondylar fossa, the central x-ray beam should be 12° (S.D. 1.7°) caudal from the femoral diaphysis in the sagittal plane and obliqued caudolateral to craniomedial 7° (S.D. 0.60°) (caudo78°proximo7° lateralcraniodistomedial oblique). Cross table positioning was used with the hip flexed and the radiograph cassette placed on the cranial surface of the stifle. However, superimposition of the tuber ischii and soft tissues caudal to the femur made 15° to 20° the best angle obtainable. There was not a significant difference (p = 0.17) in the notch width index between a 12° versus 20° angle of the central x-ray beam caudal to the femoral diaphysis, both with 7° of external rotation of the stifle. The notch width index of 0.252 obtained from radiographic measurements was not significantly different from measurements obtained grossly of 0.254 (n = 26; p = 0.69). Failure to oblique the central x-ray beam caused a significant (p = 0.0008) decrease in the apparent fossa width radiographically

  8. Myogenic potential of canine craniofacial satellite cells

    Full Text Available The skeletal fibres have different embryological origin; the extraocular and jaw-closer muscles develop from prechordal mesoderm while the limb and trunk muscles from somites. These different origins characterise also the adult muscle stem cells, known as satellite cells (SCs and responsible for the fibre growth and regeneration. The physiological properties of presomitic SCs and their epigenetics are poorly studied despite their peculiar characteristics to preserve muscle integrity during chronic muscle degeneration. Here we isolated SCs from canine somitic (SDM: vastus lateralis, rectus abdominus, gluteus superficialis, biceps femoris, psoas and presomitic (PSDM: lateral rectus, temporalis and retractor bulbi muscles as myogenic progenitor cells from young and old animals. In addition, SDM and PSDM satellite cells were obtained also from Golden retrievers affected by muscular dystrophy (GRMD. We characterised the lifespan, the myogenic potential and functions and oxidative stress of both somitic and presomitic SCs with the aim to reveal differences with ageing and between healthy and dystrophic animals. The different proliferation rate was consistent with higher telomerase activity in PSDM-SCs compared to SDM-SCs, although restricted at early passages. SDM-SCs express early (Pax7, MyoD and late (MyHC, Myogenin myogenic markers differently from PSDM-SCs resulting in a more efficient and faster cell differentiation. Taken together our results showed that PSDM-SCs elicit a stronger stem cell phenotype compared to SDM ones. Finally, myomiR expression profile reveals a unique epigenetic signature in GRMD satellite cells and miR-206, highly expressed in dystrophic SCs, seems to play a critical role in muscle degeneration. Thus, miR-206 could represent a potential target for novel therapeutic approaches.

    Full Text Available Background. Chinese medicine (CM has been used to relieve symptoms relevant to uterine fibroids. Objective. This study investigated the association between the use of CM and the incidence of uterine surgery in women with uterine fibroids. Subjects and Methods. This retrospective cohort study extracted records for 16,690 subjects diagnosed with a uterine fibroid between 2000 and 2003 from the National Health Insurance reimbursement database. The risk factors for surgery were examined via Cox proportional hazard analysis, and the difference in incidence of surgery between CM users and nonusers was compared using incidence rate ratios (IRRs derived from Poisson's models. Results. After an average follow-up period of 4.5 years, the cumulative incidence of uterine surgery was significantly lower in CM users than CM nonusers (P<0.0001. Compared to CM nonusers, CM users were more unlikely to undergo uterine surgery (adjusted hazard ratio = 0.18, 95% confidence interval (CI = 0.17, 0.19. The incidence of surgery in CM users was dramatically different from that for CM nonusers (IRR = 0.17, 95% CI = 0.16, 0.18. Conclusion. The risk of uterine surgery among fibroid patients who used CM was significantly decreased, implying an effective treatment of fibroid-related symptoms provided by CM.

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

    Canine pyometra is a dioestrus period disease in which systemic inflammatory response syndrome (SIRS) is a common outcome due to the response of the body to the bacterial infection. The purpose of this study was i) to differentiate canine pyometra and cystic endometrial hyperplasia (CEH)/mucometra by measuring serum C-reactive protein (CRP) and prostaglandin F2α metabolite (PGFM) concentrations in blood and ii) to compare serum concentrations of CRP and PGFM in bitches with a pathological uterus (pyometra or CEH/mucometra) to concentrations in bitches with a healthy uterus. Mean CRP concentrations were found significantly higher (p dogs with pyometra compared to those with CEH/mucometra or healthy uterus. However, no statistical difference could be detected between the groups for mean PGFM concentrations. Mean white blood cell count (WBC), alkaline phosphatase (ALP) and total protein concentrations were found significantly higher (p dogs with pyometra. Escherichia coli was the most frequently isolated microorganism from dogs with pyometra (64.3%). Edwardsiella spp. was detected in a single case of pyometra for the first time. In conclusion, our results demonstrate that serum CRP concentrations were increased in dogs with pyometra and thus we conclude that serum CRP concentration but not PGFM might be useful as a marker to differentiate a case of CEH/mucometra from pyometra in female dogs. To the authors' knowledge, this is the first report in which Edwardsiella spp. has been isolated in the canine uterus. PMID:24889379

    Background:Early embryonic developmental arrest is the most commonly understudied adverse outcome of pregnancy.The relevance of intrauterine infection to spontaneous embryonic death is rarely studied and remains unclear.This study aimed to investigate the relationship between intrauterine bacterial infection and early embryonic developmental arrest.Methods:Embryonic chorion tissue and uterine swabs for bacterial detection were obtained from 33 patients who underwent artificial abortion (control group) and from 45 patients who displayed early embryonic developmental arrest (trial group).Results:Intrauterine bacterial infection was discovered in both groups.The infection rate was 24.44% (11/45) in the early embryonic developmental arrest group and 9.09% (3/33) in the artificial abortion group.Classification analysis revealed that the highest detection rate for Micrococcus luteus in the early embryonic developmental arrest group was 13.33% (6/45),and none was detected in the artificial abortion group.M.luteus infection was significantly different between the groups (P < 0.05 as shown by Fisher's exact test).In addition,no correlation was found between intrauterine bacterial infection and history of early embryonic developmental arrest.Conclusions:M.luteus infection is related to early embryonic developmental arrest and might be one of its causative factors.

  17. Therapeutic analysis of bilateral uterine artery chemoembolization performed before uterine dilation and curettage for cesarean scar pregnancy

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical outcomes of bilateral uterine artery chemoembolization (UACE) followed by uterine dilation and curettage in treating cesarean scar pregnancy. Methods: A total of 104 patients with cesarean scar pregnancy, admitted to hospital during the period from Jan. 2005 to Jan. 2009, were enrolled in the study. The patients were divided into group A (control group, n=49) and group B (study group, n=55). Patients in group A received uterine dilation and curettage only, and patients in group B received additional UACE, which was performed 24-72 hours before uterine dilation and curettage was carried out. The blood loss during the operation, the time for β-human chorionic gonadotrophin (β-hCG) level going down to normal, the success rate of operation, the hospitalization days, the occurrence of complications and the menstrual situation after operation were documented. The results were analyzed and compared between the two groups. Results: In group A, 4 patients had to receive hysterectomy due to massive hemorrhage or inadequate curettage. None of the patients in group B needed to have a hysterectomy. the technical success rates of curettage for group A and group B were 91.84% and 100%, respectively. The mean blood loss in group B was (54.36±38.09) ml, which was significantly lower than that of (54.36±38.09) ml in group A (P0.05], while between those patients who had pregnancy time > 10 weeks, the blood loss in group B was much less than that of group A [(101.33±39.43) ml vs. (457.14±97.59) ml, P0.05]. The difference in hospitalization days between the patients with pregnancy time ≤ 10 weeks in two groups [(11.21±3.24) days vs. (12.68±34.56) days] was not significant (P>0.05). But for patients with pregnancy time > 10 weeks, the hospitalization days of group B was significantly shorter than that of group A (13.46±4.87 days vs. 19.34±5.72 days, P<0.01), Except for 4 patients who had received hysterectomy, all patients regained normal

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

    Objective:This comparative study was designed to assess the role of saline infusion hysterosonography in refining the diagnosis of uterine cavity abnormalities diagnosed by hysteroscopy in infertile, asymptomatic women beforein vitro fertilization/intra-cytoplasmic sperm injection (IVF/ICSI) treatment.Methods:One hundred and twenty four asymptomatic infertile women were included in this study before IVF/ICSI treatment. Hysteroscopy was done as routine procedure for uterine cavity assessment before the first attempt of IVF/ICSI treatment. Patients agreed to have an ultrasound assessment of uterine cavity with the use of saline as the contrast medium (Saline infusion hysterosonography, SIHS) beside the hysteroscopic assessment. Both hysteroscopy & SIHS procedures were scheduled post menstrual period in the early-mid follicular phase of a cycle of the same menstrual cycle, 1-3 months before starting the IVF/ICSI treatment.Results:The uterine cavity abnormalities were detected in 40.3% of the patients included in this study before IVF/ICSI treatment (17.7% endometrial polyps, 10.5% sub-mucous fibroid, 4.8% uterine septum, 3.2% uterine adhesions, 2.4% endometrial hyperplasia and 1.6% thin or atrophic endometrium). In this study, the hysteroscopy was more sensitive (98.0% versus 96.2%), more specific (100.0% versus 98.7%) and more accurate (99.2% versus 97.6%) than SIHS, and the hysteroscopy also had higher predictive values (100% versus 98% positive predictive value; 98.7% versus 97.4% negative predictive value) than SIHS during uterine cavity assessment before IVF/ICSI treatment.Conclusions: Infertile asymptomatic women should be screened for possible uterine cavity abnormalities before IVF/ICSI; SIHS is a simple, well tolerated procedure that can be used as a complementary tool to confirm the diagnosis of uterine cavity abnormalities detected by hysteroscopy.

    The current report describes an unusual presentation of uterine endometrial polyp with severe hemorrhage and cystic endometrial hyperplasia-pyometra complex in a 9.5-year-old female Doberman Pinscher. The dog presented with a 2-day history of bloody discharge from the vulva and an enlarged abdomen. The postmortem examination revealed a markedly distended right uterine horn with a large pedunculated mass (17 cm x 9 cm x 4 cm) and blood. Based on the histological findings, the diagnosis of uterine endometrial polyp was made. PMID:20453227
