    Tissue strips from the ovary, (uterine tube), and oviduct, and uterus of pregnant and nonpregnant cows were tested for their contractile response to prostaglandin F2 alpha (PGF2 alpha). When 2.1 x 10(-6)M PGF2 alpha was added to the uterine strips, tension of tissues from pregnant cows increased sharply; however, tension in tissues from nonpregnant cows only increased moderately. Similar concentrations failed to elicit any response from oviductal tissues of either group. Unlike the uterus and the oviduct, the ovaries contracted slowly and irregularly. They responded with varying degrees of stimulation; ovaries from pregnant cows with brief and mild stimulation and ovaries from nonpregnant cows with slower and relatively stronger stimulation. Results indicate that the bovine ovary contracts rhythmically and that its sensitivity to PGF2 alpha decreases during pregnancy in contrast to the bovine uterus which becomes increasingly sensitive during pregnancy.

    Metritis is a uterine disease that affects 10 to 30% of all lactating dairy cows and has detrimental effects on reproductive performance, milk production, and survival. Data regarding the identity and abundance of bacterial genes governing traits such as virulence, antibiotic resistance, and stress responses could enable identification of previously unknown agents that play a role in metritis pathogenesis. Moreover, such knowledge could lead to the development of improved treatments or preventive methods. Therefore, the objectives of this study were to characterize the uterine microbial population and to differentiate, for the first time, the microbial functional diversity in cows with metritis versus healthy cows. In addition, we aimed to identify relationships between microbial genes and postpartum uterine health. Uterine swabs were collected from 24 cows within 3 to 12 d in milk; 12 cows were diagnosed with metritis and the other 12 were healthy. Metritis was defined as a watery, reddish or brownish uterine discharge having a fetid smell, and rectal temperature greater than 39.5°C. Cows with a clear and viscous uterine discharge, not fetid or mucopurulent, were classified as healthy. Microbial metagenomic DNA from uterine swab samples was subjected to whole-genome shotgun sequencing on the Illumina MiSeq platform (Illumina Inc., San Diego, CA). The MG-RAST server (metagenomic rapid annotations using subsystems technology; http://metagenomics.anl.gov/) and STAMP software (http://kiwi.cs.dal.ca/Software/STAMP) were used to detect statistically significant differences in the abundance of taxonomic and functional features between the uterine microbial metagenomes of metritic and healthy cows. Our results showed an increased abundance of Fusobacteria and Bacteroidetes in metritic cows, confirming the potential role of those 2 taxa in the pathogenesis of metritis. The MG-RAST analysis revealed a significantly higher abundance of genes for protein transport across the

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

    Previous research has reported that diets high in protein and sulfur decreased uterine pH in cattle. The objective of this study was to determine the effect of high N and high S intake on uterine pH. Holstein (n = 15) and Angus-cross (n = 5) heifers (337.5 ± 8.4 kg of BW) were randomly assigned to 1 of 4 diets: control (CON; 13.4% CP and 0.17% S); high nitrogen (HN; CON plus urea supplement); high sulfur (HS; CON plus calcium sulfate); or both high nitrogen and sulfur (HNS). Diets were individually fed at 2.6% of BW on a DM basis using Calan gates and estrus was synchronized to occur on d 13 (d 0 = start of dietary treatment). Blood samples were collected on d -2 and daily (d 1 to 28) at 1400 h to determine concentrations of plasma urea nitrogen (PUN), sulfate (d 1, 4, 8, 12, 16, 20, 24, and 28), and progesterone. Uterine pH was measured on d 16, 20, 24, and 28 (d 3, 7, 11, and 15 of the estrous cycle). There was a treatment, time, and treatment by time interaction (P 0.11). There was no effect of time (P = 0.26) or treatment by time interaction (P = 0.71) on uterine pH. In summary, uterine pH was increased in HN and HNS compared with CON, whereas HS was intermediate and was associated with increased concentrations of PUN.

    The objective of this study was to investigate the direct effects of feed supplements niacin and betaine on the heat shock responses of in vitro cultured cells derived from bovine mammary and uterine tissues. First, we determined the mRNA expression profiles of the niacin receptor (GPR109A) in bovine tissues (liver, skin, uterus, udder, and ovary) and in cells derived from bovine mammary epithelium (mammary alveolar cells, MAC-T; bovine mammary epithelial cells, BMEC) and endometrium (bovine endometrial cells, BEND). We found that GPR109A was distributed in all examined tissues and cells, and the highest expression was in cells from skin and udder. Second, we evaluated the effects of niacin treatment on the mRNA abundance of heat shock proteins 70 and 27 (HSP70 and HSP27) in MAC-T, BMEC, and BEND under thermoneutral conditions and heat stress, and whether these effects were associated with alterations in the mRNA expression of prostaglandin E2 synthesis-related genes, including cyclooxygenase 1 and 2 (COX-1 and COX-2) and microsomal prostaglandin E synthase 1 and 2 (mPGES-1 and mPGES-2). Quantitative PCR data indicated that niacin suppressed HSP70 mRNA expression in BMEC and both HSP70 and HSP27 in BEND under thermoneutral conditions. Only COX-2 expression was downregulated by niacin in BMEC; other prostaglandin E2 synthesis-related genes stayed unaltered in BMEC and BEND. The mRNA abundance of HSP70, COX-1, COX-2, and mPGES-1 were elevated in niacin-treated MAC-T. During heat stress, niacin increased mRNA levels of HSP70 and HSP27 in MAC-T and HSP27 in BEND, but decreased HSP70 in BMEC. Although mPGES-2 was stimulated by niacin in BEND, the mRNA expression of prostaglandin E2 synthesis-related genes were consistent with neither HSP70 nor HSP27 expression patterns in niacin-treated BMEC and MAC-T. These data suggest that the effects of niacin on heat shock protein expression and prostaglandin E2 synthesis were not well coupled in these cells. Finally, we tested the

    We investigated the concentration of the bacterial endotoxin lipopolysaccharide (LPS) in the blood, ovarian follicular fluid and uterine fluid of a clinical case of bovine metritis. A 2-year-old lactating Holstein cow exhibited continuous fever >39.5°C for more than 2 weeks after normal calving. The cow produced a fetid, watery, red-brown uterine discharge from the vagina and was diagnosed with metritis. The LPS concentrations in plasma and uterine fluid were 0.94 and 6.34 endotoxin units (EU)/ml, respectively. One of seven follicles showed an extremely high level of LPS (12.40 EU/ml) compared to the other follicles (0.62–0.97 EU/ml). These results might suggest the presence of high concentration of LPS in follicles in cows with postpartum metritis. PMID:25223344

    Full Text Available The use of PGF2 α is based on its luteolytic effect causing regression of corpus luteum and allows development of dominant follicle on the ovary that result in estrus and ovulation in 72 to 96 hours after its administration. Moreover, the PGF2 α also causes relaxation of cervix and smooth muscle contractions of uterus. The use of PGF2 α may provide microbial resistance in uterine environment, on one hand and can favour and enhance body defense mechanism / phagocytic activity on the other hand. PGF2 α is widely used to get rid of from the conditions like luteal cystic ovarian disease, persistent corpus luteum, endometritis, abnormal pregnancy, pyometra, retention of placenta and mummification. It has been now in vogue to administer PGF2 α or its analogue in early postpartum cows and buffaloes in order to hasten early resumption of cyclic ovarian activity and thereby to increase the reproductive efficiency.

    Uterine biopsies were collected at cycle days 1 (oestrous), 8, 15 and 19 in six cows. Unfixed cryostat sections were used to immunolocalise collagen types I, III, IV and VI by an indirect FITC method. Collagen I was sparsely found in the endometrium where it formed a fine meshwork of thin fibres directly below the surface epithelium, clearly visible only at cycle days 8 and 15. Collagen III formed the bulk of connective tissue fibres and was arranged in fine aggregates within the superficial endometrial stroma, while in the deeper areas it consisted of many thick fibre bundles. Collagen IV was found in basement membranes underlying all endometrial epithelia. Furthermore, it surrounded smooth muscle cells of blood vessels. A few single fibrils also stained positively within the endometrial stroma, more numerous at cycle days 1 and 19 as compared to days 8 and 15. Collagen VI formed a mesh of fine and pericellularly situated fibrils within the endometrial stroma. The contribution of the collagen types studied to the connective tissue of caruncles, blood vessels, lymph follicles, and myometrium is also reported. The results of the present study indicate that the connective tissue of the bovine uterine wall is composed of different collagen types, which exhibit a characteristic distribution pattern each. The day of cycle may influence amounts and organisation of collagen types I and IV as demonstrated here at the light-microscopical level. Copyright 2000 S. Karger AG, Basel

    Acidified extracts of pregnant bovine uterus were found to contain a heparin-affinity polypeptide(s). The eluted peak was assayed in the Chandler loop method for whole blood and fibrin thrombus generation. Significant differences in the mean weight and size of whole blood thrombi (243.5 +/- 50 mg and 3.5 cm +/- 0.6 cm) occurred with 1 microgram of purified polypeptide when compared to control samples containing albumin (47.87 +/- .30 g and 0.8 cm +/- 0.3 cm). This activity was detected by the Chandler loop method with 100 ng to 10 micrograms of protein when analyzed in a dose-response fashion. When tested for fibrin thrombus formation this activity persisted. Experiments with 125I fibrinogen revealed no net increase or decrease of uptake into whole blood thrombi when purified polypeptide was added. The heparin-affinity polypeptide(s) possessed a molecular weight of approximately 6-4 kDa when examined by SDS-PAGE. We have therefore designated this polypeptide as low molecular weight-uterine derived factor (LMW-UDF).

    Full Text Available Reproductive performance of dairy cows has a direct impact on herd productivity. Infectious agents, such as Bluetongue Virus (BTV and Bovine Leukemia Virus (BLV, are associated with reproductive failure. However, it remains unknown if these viruses are present in the uterus and cause gestational loss. This study used molecular methods to assess if BTV and BLV can be detected in the uterus of serologically positive dairy cows with a record of abortions, stillbirths and repeat breeding (n=23 and without a record of reproductive problems (n =23. The cows came from three dairy herds of the state of Minas Gerais, Brazil. BTV was not detected in any of the uterine biopsies. Proviral DNA of BLV was detected in 54.5 % of the seropositive cows, but positivity for BLV in the uterus was not associated with the existence of reproductive problems. In conclusion, this study shows that BLV, but not BTV, is present in the uterus of seropositive cows, regardless of reproductive performance.

    Full Text Available The aim of the study was to evaluate the effect of temperature on apoptosis of bovine blood eosinophil granulocytes in vitro. Heparinised bovine blood was incubated for 1, 4 and 24 h under following temperatures: 4, 23 and 37 °C. UV irradiation was used as positive control of apoptosis. Eosinophil granu­locytes apoptosis was detected by flow cytometry after simultaneous staining with Annexin-V and propidium iodide. From selected temperatures, 4 °C induced the eosinophil granulocytes apoptosis least. The proportion of apoptotic eosinophil granulocytes amounted to (mean ± SD 1.65 ± 0.46%; 1.76 ± 0.36%; 4.78 ± 1.70% after 1, 4 and 24 h incubation, respectively.

    Full Text Available ABSTRACT The medium for storing biological tissues is of great importance for their optimal use in surgery. Glycerin has been proven efficient for storing diverse tissues for prolonged time, but the preservation of the bovine amniotic membrane in glycerin 99% at room temperature has never been evaluated to be used safely in surgical procedures. This study evaluated the preservation of 80 bovine amniotic membrane samples stored in glycerin 99% at room temperature. The samples were randomly divided evenly into four groups. Samples were microbiologically tested after 1, 6, 12 and 48 months of storage. The presence of bacteria and fungi in the samples was evaluated by inoculation on blood agar and incubation at 37 ºC for 48 hours and on Sabouraud agar at 25 ºC for 5 to 10 days. No fungal or bacterial growth was detected in any of the samples. It was concluded that glycerin is an efficient medium, regarding microbiology, for preserving pre-prepared bovine amniotic membrane, keeping the tissue free of microorganisms that grow in the media up to 48 months at room temperature.

    In this study, we have implemented T2-based monitoring of near-field heating in patients undergoing HIFU ablation of uterine fibroids using Insightec ExAblate system. In certain areas, near-field heating can reach 18°C and the tissue may experience sustained heating of more than 10°C for the period of 2 hours or more. This indicates a cumulative thermal dose that may cause necrosis. Our results show the feasibility and importance of measuring near-field heating in subcutaneous fat.

    Uterine anomalies are one of the most common parental causes of recurrent pregnancy loss, occurring in about 19% of patients. Congenital uterine anomalies are most likely caused by HOX gene mutations, although the mechanism is probably polygenic. There are no known environmental causes other than estrogenic endocrine disruptors such as diethylstilbestrol. Acquired uterine anomalies may result from uterine trauma (adhesions) or benign growths of the myometrium (fibroids) or endometrium (polyps). Although randomized controlled trials are lacking, surgical treatment is recommended for repair of uterine septa, and for removal of severe adhesions and submucosal fibroids, especially if no other causes are identified.

    Full Text Available Abstract Herein we firstly reported a simple, environment-friendly, controllable synthetic method of CuSe nanosnakes at room temperature using copper salts and sodium selenosulfate as the reactants, and bovine serum albumin (BSA as foaming agent. As the amounts of selenide ions (Se2− released from Na2SeSO3 in the solution increased, the cubic and snake-like CuSe nanostructures were formed gradually, the cubic nanostructures were captured by the CuSe nanosnakes, the CuSe nanosnakes grew wider and longer as the reaction time increased. Finally, the cubic CuSe nanostructures were completely replaced by BSA–CuSe nanosnakes. The prepared BSA–CuSe nanosnakes exhibited enhanced biocompatibility than the CuSe nanocrystals, which highly suggest that as-prepared BSA–CuSe nanosnakes have great potentials in applications such as biomedical engineering.

    This work presents both analytical and experimental results of the effect of unfiltered natural solar radiation on the thermal and dynamic mechanical properties of Boran bovine leather at both pickling and tanning stages of preparation. Samples cut from both pickled and tanned pieces of leather of appropriate dimensions were exposed to unfiltered natural solar radiation for time intervals ranging from 0 h (non-irradiated) to 24 h. The temperature of the dynamic mechanical analyzer was equilibrated at 30°C and increased to 240°C at a heating rate of 5°C \\cdot Min^{-1}, while its oscillation frequency varied from 0.1 Hz to 100 Hz. With the help of thermal analysis (TA) control software which analyzes and generates parameter means/averages at temperature/frequency range, the graphs were created by Microsoft Excel 2013 from the means. The viscoelastic properties showed linear frequency dependence within 0.1 Hz to 30 Hz followed by negligible frequency dependence above 30 Hz. Storage modulus (E') and shear stress (σ ) increased with frequency, while loss modulus (E''), complex viscosity (η ^{*}) and dynamic shear viscosity (η) decreased linearly with frequency. The effect of solar radiation was evident as the properties increased initially from 0 h to 6 h of irradiation followed by a steady decline to a minimum at 18 h before a drastic increase to a maximum at 24 h. Hence, tanning industry can consider the time duration of 24 h for sun-drying of leather to enhance the mechanical properties and hence the quality of the leather. At frequencies higher than 30 Hz, the dynamic mechanical properties are independent of the frequency. The frequency of 30 Hz was observed to be a critical value in the behavior in the mechanical properties of bovine hide.

    There has been increasing interest to measure core-body temperature in cattle using internal probes. This study examined the placement of HOBO water temperature probe with an anchor, referred to as the "sensor pack" (Hillman et al. Appl Eng Agric ASAE 25(2):291-296, 2009) in the vagina of multiparous Holstein cows under grazing conditions. Two types of anchors were used: (a) long "fingers" (4.5-6 cm), and (b) short "fingers" (3.5 cm). The long-finger anchors stayed in one position while the short-finger anchors were not stable in one position (rotate) within the vagina canal and in some cases came out. Vaginal temperatures were recorded every minute and the data collected were then analyzed using exponential mixed model regression for non-linear data. The results showed that the core-body temperatures for the short-finger anchors were lower than the long-finger anchors. This implied that the placement of the temperature sensor within the vagina cavity may affect the data collected.

    2014-09-01

    Full Text Available The purpose of this study was to assess whether reducing environmental temperature will lead to increased chondrocyte viability following injury from a single-dose of local anesthetic treatment. Bovine articular chondrocytes from weight bearing portions of femoral condyles were harvested and cultured. 96-well plates were seeded with 15,000 chondrocytes per well. Chondrocytes were treated with one of the following conditions: ITS Media, 1x PBS, 2% lidocaine, 0.5% bupivacaine, or 0.5% ropivacaine. Each plate was then incubated at 37°C, 23°C, or 4°C for one hour and then returned to media at 37°C. Chondrocyte viability was assessed 24 hours after treatment. Chondrocyte viability is presented as a ratio of the fluorescence of the treatment group over the average of the media group at that temperature (ratio ± SEM. At 37°C, lidocaine (0.35 ± 0.04 and bupivacaine (0.30 ± 0.05 treated chondrocytes show low cell viability when compared to the media (1.00 ± 0.03 control group (p < 0.001. Lidocaine treated chondrocytes were significantly more viable at 23°C (0.84 ± 0.08 and 4°C (0.86±0.085 than at 37°C (p < 0.001. Bupivacaine treated chondrocytes were significantly more viable at 4°C (0.660 ± 0.073 than at 37°C or 23°C (0.330 ± 0.069 (p < 0.001 and p = 0.002 respectively. Reducing the temperature from 37°C to 23°C during treatment with lidocaine increases chondrocyte viability following injury. Chondrocytes treated with bupivacaine can be rescued by reducing the temperature to 4°C.

    Full Text Available Overheating is constantly mentioned as a risk factor for bone necrosis that could compromise the dental implant primary stability. Uncontrolled thermal injury can result in a fibrous tissue, interpositioned at the implant-bone interface, compromising the long-term prognosis. The methods used to record temperature rise include either direct recording by thermocouple instruments or indirect estimating by infrared thermography. This preliminary study was carried out using bovine bone and a different method of temperatures rising estimation is presented. Two different types of drills were tested using fluoroptic thermometer and the effectiveness of this alternative temperature recording method was evaluated.

    The objective of these experiments was to identify the cellular mechanisms by which oxytocin stimulates prostaglandin (PG) F2 alpha synthesis in bovine endometrial tissue. Uteri were collected on the day after spontaneous luteal regression. Caruncular endometrial explants were dissected and incubated in vitro to assess PGF2 alpha release or phospholipase (PL) C activity. Oxytocin (10(-6) M) stimulated PGF2 alpha release and PLC activity within 30 min of incubation (P PGF2 alpha release was not detected until 10(-8) M (P PGF2 alpha release at 10(-6) M and higher doses (P PGF2 alpha release at 10(-5) M and higher doses (P PGF2 alpha release induced by A1F4-, a nonspecific stimulator of G protein (10(-5) M) and melittin (10(-4) M; P 0.10). By comparing the time course of stimulation and dose-response relationships between PGF2 alpha and PLC activity, it appears that oxytocin may stimulate PGF2 alpha secretion by activating PLC. The effects of melittin and aristolochic acid indicate that PLA2 may play a role in mediating the stimulatory effect of oxytocin on PGF2 alpha secretion, as well.

    A fast and simple flow-through optosensor was designed and characterized for the direct screening of four tetracycline (TCC) antibiotics (tetracycline, oxytetracycline, chlortetracycline and doxycycline) in water and bovine milk samples. The proposed optosensor provides rapid binary yes/no overall responses, being appropriate for the screening of this family of antibiotics above or below a pre-set concentration threshold. The experimental set-up is based on a flow-injection manifold coupled on-line to a phosphorescence detector. Aliquots of the samples are pretreated with Eu(III) to form room temperature phosphorescent metal chelates and injected in the flow manifold. Those chelates are then on-line retained on a conventional flow-cell (packed with polymeric Amberlite XAD-4 particles) which is placed inside the cell holder of the phosphorimeter. After the emission is registered, the antibiotic-metal complexes are eluted from the packed resin with 1 M HCl (for milk samples a second regeneration step, using methanol, should be performed). A sample throughput of about 20 samples per hour was obtained. Optimum experimental conditions include a pH 9, a Eu(III) concentration of 2 x 10{sup -4} M and 8 mM sodium sulphite as chemical deoxygenant. The phosphorescence emitted by the europium-TCC complexes was measured at 394 and 617 nm for excitation and emission wavelengths, respectively. The unreliability region, given by the probability of false positives and false negatives, respectively (set at 5% in both cases) was in the range between 0.2 and 11.6 nM for detection of tetracyclines in water samples (at a cut-off level of 4 nM) and in the range between 165 and 238 nM for detection of tetracyclines in milk (cut-off level fixed at the normative EU level of 200 nM). Finally, the applicability of the proposed screening optosensor was tested for the reliable control of tetracyclines in contaminated and uncontaminated water and milk samples.

    The subject of present work was to predict internal temperature gradients developed during freezing of bovine sperm diluted in extender, packaged in 0.5 ml French plastic straws and suspended in static liquid nitrogen vapor at -100 degree C. For this purpose, a mathematical heat transfer model previously developed to predict freezing times (phase change was considered) of semen/extender packaged in straw was extended to predict internal temperature gradients during the cooling/freezing process. Results showed maximum temperature differences between the centre and the periphery of semen/extender "liquid" column was 1.5 degree C for an external heat transfer coefficient, h = 15 W per (m(2) K), and only 0.5 degree C for h = 5 W per (m(2) K). It is concluded that if a thermocouple wire were inserted in a 0.5 ml plastic straw to monitor the freezing process in nitrogen vapor, its radial position would have little importance since expected internal gradients may be safely neglected. This finding facilitates the interpretation of freezing rates in 0.5 ml plastic straws immersed in nitrogen vapor over liquid nitrogen, a widely used method for cryopreservation of bovine spermatozoa.

    Full Text Available The objective of this study was to evaluate the effect of storage under various conditions on the concentrations of major bovine acute phase protein—serum amyloid A, and its mammary isoform. Blood samples were taken from seven clinically healthy calves, and milk samples from six clinically healthy dairy cows. The harvested blood serum and the milk samples were fractioned into aliquots. One aliquot was analyzed on the day of collection without storage. The second aliquots were stored at 4°C for 1 day, the remaining aliquots were kept frozen at −18°C for 2, 7, 14, and 21 days, and then analyzed. Blood serum was analyzed for serum amyloid A (SAA. The concentrations of mammary isoform of SAA (M-SAA were measured in milk samples. Over time, the concentrations of SAA in serum showed a tendency of significant decrease during storage at −18°C (P<0.01. Similarly, the values of M-SAA decreased significantly in samples maintained at freezer temperatures (P<0.001. In the refrigerated samples, we found non-significantly lower values of SAA, as well as M-SAA. Presented results indicate that the storage temperature and duration may markedly affect the concentrations of bovine SAA and M-SAA.

    Full Text Available Teratomas are the most commonly diagnosed germ cell tumors and occur primarily in testes and ovaries. Platinum-based therapy followed by surgical resection of the residual lesion is generally the recommended treatment. In contrast, immature uterine teratomas are rare, with few cases reported in the literature. Moreover, there is no standard treatment for these tumors. Non-puerperal uterine inversion is also rare in women younger than 45 years of age, and neoplastic lesions are responsible for this condition. Here, we report a case of an immature uterine teratoma associated with uterine inversion. The patient underwent surgery followed by adjuvant chemotherapy and continues to be monitored.

    The recently introduced Open Pulled Straw (OPS) vitrification technique has successfully been used for cryopreserving porcine embryos as well as for bovine embryos and oocytes. The aim of this work is to investigate several factors on the in vitro survival of bovine blastocysts. In 5 experiments, a total of 862 in vitro produced blastocysts and expanded blastocysts was vitrified and warmed using the OPS technology, then cultured in vitro for an additional 3 days. The culture medium in Experiments 1 to 4 was SOFaa with supplements and 5% calf serum (CS). In Experiment 1, the replacement of TCM-199 + 20% CS with PBS + 20% CS in the holding medium during vitrification and warming did not result in significant differences in the re-expansion (92 vs 95%) and hatching rates (79 vs 72%). In Experiment 2, the PBS holding medium was supplemented with either 20% CS, 5 mg/mL bovine serum albumin (BSA) or 3 mg/mL polyvinylalcohol (PVA). Although the re-expansion rates did not differ (98, 95 and 93%, respectively), there was a decrease in the hatching rate after vitrification with PVA (77 and 78 vs 51%, respectively). In Experiment 3, the influence of temperature of equilibration media prior to and rehydration media after the vitrification was investigated. When the temperature of these media was adjusted to 20 degrees C instead of the standard 35 degrees C, both the re-expansion and the hatching rates decreased markedly. However, increasing the time of equilibration with the diluted cryoprotectant solution at 20 degrees C eliminated these differences. In Experiment 4, the ethylene-glycol and dimethyl sulfoxide cryoprotectant mixture was replaced with ethylene glycol-ficoll-trehalose solution. No difference in the re-expansion (89 vs 96%, respectively) or hatching rate (79 vs 84%, respectively) was detected. In Experiment 5, the vitrified-warmed blastocysts were cultured in SOFaa medium supplemented with 5% CS or 5 mg/mL BSA. Although the re-expansion rates were identical in

    Full Text Available Luminescent quantum dots (QDs with unique optical properties have potential applications in bio-imaging. The interaction between QDs and bio-molecules is important to the biological effect of QDs in vivo. In this paper, we have employed fluorescence correlation spectroscopy (FCS to probe the temperature- and pH-dependent interactions between CdSe QDs with carboxyl (QDs-COOH and bovine serum albumin (BSA in buffer solutions. The results have shown that microscopic dissociation constant K′D is in the range of (1.5 ± 0.2 × 10−5 to (8.6 ± 0.1 × 10−7 M, the Hill coefficient n is from 0.4 to 2.3, and the protein corona thickness is from 3.0 to 9.4 nm. Variable-temperature measurements have shown both negative values of ∆H and ∆S for BSA adsorption on QDs-COOH, while pH has a profound effect on the adsorption. Additional, FCS measurement QDs-COOH and proteins in whole mice serum and plasma samples has also been conducted. Finally, simulation results have shown four favored QD binding sites in BSA.

    Bio-decontamination of surfaces by means of atmospheric pressure plasma is nowadays extensively studied as it represents promising alternative to commonly used sterilization/decontamination techniques. The non-equilibrium atmospheric pressure plasmas were already reported to be highly effective in removal of a wide range of biological residual from surfaces. Nevertheless the kinetics of removal of biological contamination from surfaces is still not well understood as the majority of performed studies were based on ex-situ evaluation of etching rates, which did not allow investigating details of plasma action on biomolecules. This study therefore presents a real-time, in-situ ellipsometric characterization of removal of bovine serum albumin (BSA) from surfaces by low-temperature atmospheric plasma jet operated in argon. Non-linear and at shorter distances between treated samples and nozzle of the plasma jet also non-monotonic dependence of the removal rate on the treatment duration was observed. According to additional measurements focused on the determination of chemical changes of treated BSA as well as temperature measurements, the observed behavior is most likely connected with two opposing effects: the formation of a thin layer on the top of BSA deposit enriched in inorganic compounds, whose presence causes a gradual decrease of removal efficiency, and slight heating of BSA that facilitates its degradation and volatilization induced by chemically active radicals produced by the plasma.

    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)

    Synchronous and continuous measurement of body (BT) and scrotal temperature (ST) without adverse welfare or behavioural interference is essential for understanding thermoregulation of the bull testis. This study compared three technologies for their efficacy for long-term measurement of the relationship between BT and ST by means of (1) temperature sensitive radio transmitters (RT), (2) data loggers (DL) and (3) infrared imaging (IRI). After an initial pilot study on two bulls to establish a surgical protocol, RTs and DLs were implanted into the flank and mid-scrotum of six Wagyu bulls for between 29 and 49 days. RT frequencies were scanned every 15 min, whilst DLs logged every 30 min. Infrared imaging of the body (flank) and scrotum of each bull was recorded hourly for one 24-h period and compared to RT and DL data. After a series of subsequent heat stress studies, bulls were castrated and testicular tissue samples processed for evidence of histopathology. Radio transmitters were less reliable than DLs; RTs lost >11 % of data, whilst 11 of the 12 DLs had 0 % data loss. IRI was only interpretable in 35.8 % of images recorded. Pearson correlations between DL and RT were strong for both BT ( r > 0.94, P 0.80, P surgical sutured sites when bulls were castrated, there was no evidence of testicular adhesion and normal active spermatogenesis was observed in six of the eight implanted testicles. There was no significant correlation of IRI with either DL or RT. We conclude that DLs provided to be a reliable continuous source of data for synchronous measurement of BT and ST.

    Normal non-pigmented bovine eyelids in two Hereford cows under general anesthesia were treated with diode laser (805 nm) in a power range of 3 - 6.5 watts. Tissue temperatures were measured in areas infiltrated with 0.25% indocyanine green (ICG) solution and in non-infiltrated areas. Targeted tissue was laser treated at post-injection time intervals of 1 to 60 minutes. Temperatures were measured with a computerized temperature sensing program using hypodermic needle thermistors. Trial objectives were to establish power/chromophore concentration/time parameters to create tumor and peri-tumor tissue temperatures of 50 degrees Celsius without causing epidermal vaporization. Tissue temperature of 50 degrees Celsius has been established as the temperature producing coagulative necrosis of squamous cell carcinoma tumor tissue in 30 seconds. This temperature was produced in chromophore-enhanced tissue bit without repeatable confidence. Bovine ocular squamous cell carcinoma (BOSCC)-affected eyes and eyelids have been successfully treated with carbon dioxide focused and defocused laser with and without chromophore enhanced diode laser (805 nm) energy. The need for tumor staging and procedure standardization requires further investigation to determine laser power/chromophore concentration, and issue exposure times.

This video uses an animation and footage from a uterine transplantation procedure to review the steps and techniques involved in performing a uterine transplant. Academic, multisite medical center. A reproductive-age patient with Mayer-Rokitansky-Kuster-Hauser syndrome. Transplantation of a viable uterus from a deceased donor. Assessment of posttransplantation uterine graft viability. This video article describes the essential steps in the uterine transplant process, including selecting an appropriate donor with no history of infertility or uterine malformations. Furthermore, a deceased donor should exhibit brain death but not cardiac death. We also review our inclusion criteria for suitable recipients. In this video we outline the key steps in a uterine transplantation procedure and demonstrate footage from an actual transplant procedure. These steps include establishing bilateral end-to-side vascular anastomoses between the donor uterine artery and vein and the recipient's external iliac vessels. Once this has been completed and reperfusion noted of the donor uterus, connection to the recipient vaginal cuff is then performed. Uterine transplantation, although currently experimental, has gained the potential to become the first true treatment for uterine factor infertility. This procedure can become a promising option for the approximately 1.5 million women worldwide for whom pregnancy is not possible because of the absence of the uterus or presence of a nonfunctional uterus. Deceased donor uterine transplantation will further serve to broaden accessibility for this procedure. Copyright © 2016 American Society for Reproductive Medicine. Published by Elsevier Inc.

    2007-03-01

    Full Text Available Bovine pericardium bioprosthesis has become a commonly accepted device for heart valve replacement. Present practice relies on the measurement of shrinkage temperature, observed as a dramatic shortening of tissue length. Several reports in the last decade have utilized differential scanning calorimetry (DSC as an alternative method to determine the shrinkage temperature, which is accompanied by the absorption of heat, giving rise to an endothermic peak over the shrinkage temperature range of biological tissues. Usually, freeze-drying microscope is used to determine collapse temperature during the lyophilization of solutions. On this experiment we used this technique to study the shrinkage event. The aim of this work was to compare the results of shrinkage temperature obtained by DSC with the results obtained by freeze-drying microscopy. The results showed that both techniques provided excellent sensitivity and reproducibility, and gave information on the thermal shrinkage transition via the thermodynamical parameters inherent of each method.

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

    Uterine arteriovenous malformations (AVM) may be responsible for vaginal bleeding potentially life-threatening. They are most often acquired following uterine trauma (curettage, cesarean section, artificial delivery/uterus examination) in association with pregnancy or gestational trophoblastic disease. We report three cases of patients having uterine AVM after curettage. The diagnostic management is important to avoid differential diagnoses (intra-uterine retention, hemangioma, gestational trophoblastic disease). It is based on serum hCG measurement and Doppler ultrasound, then confirmed on dynamic angio-MRI, which tends to replace angiography as first-line. The therapeutic management in cases of symptomatic AVMs is mostly embolization which offers the possibility for childbearing. Current data on subsequent pregnancies is reassuring even if they remain limited. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

    To evaluate the effect of multiple refreshment/activation cycles and temperature on the reaction rate of sodium hypochlorite (NaOCl) with bovine dentine during ultrasonic activated irrigation (UAI) under laboratory conditions. The root canal walls of 24 standardized root canals in bovine incisors were exposed to a standardized volume of NaOCl at different temperatures (24 °C and 38 °C) and exposure times (20, 60 and 180 s). The irrigant was refreshed and ultrasonically activated four times for 20 s followed by a 40 s rest interval, with no refreshment and no activation as the controls. The reaction rate was determined by measuring the amount of active chlorine in the NaOCl solution before and after being exposed to dentine during the specific experimental conditions. Calorimetry was used to measure the electrical-to-sonochemical conversion efficiency during ultrasonic activation. Refreshment, activation and exposure time all increased the reaction rate of NaOCl (P reaction rate of NaOCl (P > 0.125). The reaction rate of NaOCl with dentine is enhanced by refreshment, ultrasonic activation and exposure time. Temperature rise of irrigant during ultrasonic activation was not sufficient to alter the reaction rate. © 2013 International Endodontic Journal. Published by John Wiley & Sons Ltd.

    2013-11-01

    Full Text Available Uterine health condition plays a very important role in evoking cattle fertility or infertility. The major prerequisites to enhance and achieve postpartum bovine fertility are a normal physiological uterine involution and re-establishment of ovarian cyclicity. Uterine function is usually compromised in cattle by bacterial contamination of the uterine lumen after parturition, and pathogenic bacteria often persist, causing uterine disease, a key cause of infertility in cattle. The causes of uterine diseases are complex and multifactorial; therefore, a broad approach must be taken when trying to identify the causes or prevent them. The dairy cow undergoes a state of negative energy during the transition into lactation, which leads to immunosuppression and increased susceptibility to disease. The main risk factors for uterine diseases are dystocia, stillbirth, abortion, prolapsed uterus, retained placenta. Uterine diseases are associated with lower conception rates, increased intervals from calving to first service or conception, and more cattle culled for failure to conceive. Health and management strategies should be applied to avoid the various risk factors that may affect cattle around parturition and postpartum. This review article will through light on conditions associated with uterine health and disorders and their significance on future fertility of parturient dairy cows.

    2017-02-01

    Full Text Available A uterine artery pseudoaneurysm (UAP can occur after a traumatic event to the uterus, and cause massive bleeding. A uterine manipulator has been widely used for gynecologic laparoscopic surgery as basically an atraumatic instrument. We describe here a woman with a UAP caused by a uterine manipulator. She underwent laparoscopic ovarian cystectomy with a uterine manipulator due to torsion of a left ovarian cyst. Eleven days later, she came to our hospital with massive vaginal bleeding. Transvaginal Color Doppler ultrasound showed an intrauterine cystic mass with swirling blood flow, and three-dimensional arterial imaging from computed tomography revealed a UAP on the left side. Selective uterine artery angiography demonstrated a pseudoaneurysm in the distal portion of the left uterine artery, and embolization was performed successfully. A UAP should be taken into consideration in uterine bleeding after the use of a uterine manipulator.

    The objective of this study was to determine the effect of storage temperature during ovary transport on the developmental competence of bovine oocytes for use in somatic cell nuclear transfer (SCNT). Ovaries obtained from a slaughterhouse were stored in physiological saline for 3-4h at one of the three temperatures: 15 °C, 25 °C, or 35 °C. The developmental competence of oocytes used for SCNT was ascertained by cleavage and blastocyst formation rate, total cell number, apoptosis index, and the relative abundance of Bax and Hsp70.1 in day 7 blastocysts. Ovaries stored at 35 °C for 3-4h reduced the recovery rate of grade I and II oocytes compared with those stored at 25 °C or 15 °C (45.1±0.7% vs. 76.7±1.2% or 74.8±2.0%, Pstorage temperature of 15 °C for a 3-4h period had a significant beneficial effect on the quality and developmental competence of oocytes used for SCNT due to the alleviation of stresses on the oocytes compared with those subjected to storage temperatures of 25 °C or 35 °C.

    Bovine beta-lactoglobulin was hydrolyzed with trypsin or chymotrypsin in the course of heat treatment at 55, 60 and 65 C at neutral pH. At these temperatures beta-lactoglobulin undergoes significant but reversible structural changes. In the conditions used in the present study, beta...... formed in the early steps of hydrolysis indicated that both enzymes effectively hydrolyzed some regions of beta-lactoglobulin that were transiently exposed during the physical treatments and that were not accessible in the native protein.

    Passive local immunization against dental caries is a promising approach to its prevention, as clinical evidence of active oral or nasal immunization is still limited and controversial. By means of systemic immunization of pregnant cows with a multivalent vaccine, high titres of IgG antibodies against human cariogenic bacteria, Streptococcus mutans and Streptococcus sobrinus, were produced in bovine colostrum. The purified immune product (IP) of this preparation has a number of anticariogenic properties, such as inhibition of streptococcal adherence to saliva-coated hydroxyapatite and inhibition of glucosyltransferase enzymes. This study investigated whether IP antibodies remained active and functional when added to ultra-high temperature (UHT)-treated milk or to Lactobacillus rhamnosus GG (LGG)-fermented milk stored for an extended time. LGG was chosen because of its widely known health benefits in humans and animals. A commercial UHT toddler's milk was supplemented with IP and stored for 2 months at 5, 21 and 30 degrees C. The antistreptococcal titres in UHT milk did not decline at any temperature during storage, and UHT-IP inhibited the adherence of S. mutans for up to 2 months. This was not the case with UHT toddler's milk without IgG antibodies. Milk was fermented with live LGG cells in the presence or absence of 5% IP. The antistreptococcal titres declined to about 30% of the original titres after storage. Fresh milk alone slightly enhanced streptococcal adhesion but fresh milk with IP inhibited the adherence of S. mutans by over 50%. LGG-positive fermented milk without antibodies also inhibited (P UHT immune milk, the activity of antibodies against cariogenic streptococci was maintained during the expected shelf-life of these products. From the anticariogenic point of view it may be beneficial to add bovine-specific antibodies against mutans streptococci to probiotic LGG-containing milk products.

    Embolization has become a first-line treatment for symptomatic uterine fibroid tumors. Selective catheterization and embolization of both uterine arteries, which are the predominant source of blood flow to fibroid tumors in most cases, is the cornerstone of treatment. Although embolization for treatment of uterine fibroid tumors is widely accepted, great familiarity with the normal and variant pelvic arterial anatomy is needed to ensure the safety and success of the procedure. The uterine artery classically arises as a first or second branch of the anterior division of the internal iliac artery and is usually dilated in the presence of a uterine fibroid tumor. Angiography is used for comprehensive pretreatment assessment of the pelvic arterial anatomy; for noninvasive evaluation, Doppler ultrasonography, contrast material-enhanced magnetic resonance (MR) imaging, and MR angiography also may be used. After the uterine artery is identified, selective catheterization should be performed distal to its cervicovaginal branch. For targeted embolization of the perifibroid arterial plexus, injection of particles with diameters larger than 500 mum is generally recommended. Excessive embolization may injure normal myometrium, ovaries, or fallopian tubes and lead to uterine necrosis or infection or to ovarian failure. Incomplete treatment or additional blood supply to the tumor (eg, via an ovarian artery) may result in clinical failure. The common postembolization angiographic end point is occlusion of the uterine arterial branches to the fibroid tumor while antegrade flow is maintained in the main uterine artery.

    Arteriovenous malformation (AVM) can arise in various organs, particularly the brain, but it is rare in the uterus. Uterine AVM is potentially lethal and is generally associated with uterine trauma, such as dilatation and curettage, therapeutic abortion or uterine surgery. On the other hand, uterine myoma is the most common benign gynecological tumor, but uterine cervical myoma is rare and grows in the extraperitoneal space, with development of complex capillary networks within the tumor. Cervical myoma surgery is therefore a difficult operation with a risk of massive bleeding. We report herein a patient with uterine AVM formed within a large cervical myoma in a postmenopausal woman. The patient was a 55-year-old Japanese woman who complained of lower abdominal distension. Ultrasonography, computed tomography and magnetic resonance imaging showed an 18 × 20-cm uterine cervical tumor with dilatation of numerous vessels. Pelvic angiography was scheduled to provide accurate diagnosis and to minimize intraoperative blood loss. In fact, preoperative pelvic angiography allowed us to identify the true feeding artery and drainage veins. Occlusion of the feeding artery with a balloon device is effective in decreasing intraoperative bleeding. Abdominal total hysterectomy was performed as the surgical management of this uterine AVM. Prophylactic endovascular balloon occlusion of the ipsilateral internal iliac artery reduced the amount of hemorrhage during surgery, although blood transfusion was needed in our patient. In conclusion, preoperative embolosclerotherapy should be considered as a treatment option in patients with AVM present in a large uterine cervical myoma.

    After characterizing 2 types of patients presenting with tubal infertility (1 that is "as a rule overweight (the uterus is fixed (and there is easily palpable tubo-uterine pathology," and 1 that is "slim, young, intelligent and often beautiful", 12 1-sentence suggestions are made to increase the success of tubo-uterine implantations in the second type of presenting patient (because the first group has, in the author's mind, disappointing prognosis). Figures are the bulk of the document, with 3 figures demonstrating the type of operation, 3 showing the scheme of the operation, 1 figure showing a posterior view of the implanted tube in utero with a polyethylene prosthesis in situ down to the cervix, and 1 figure showing the instruments used in the operation. A few points of experience the author shares are: 1) operate immediately after a menstrual period; 2) give antibiotics prophylactically and after the procedure; 3) use a Bonney Myomectomy Clamp to elevate the uterus; 4) never use a knife or bistoury at the cornua; 5) use polyethylene rods, when available; and 6) caesarean section is the indicated delivery route after tubo-uterine implantation. Out of 38 patients with the requisite history and findings who have been operated on by this author, 14 have gone to full-term, i.e., 36.1%; 2 have aborted, giving a pregnancy rate of 42.2%, and there was 1 ectopic pregnancy.

    On 80 bovine hindclaws from slaughtered cows a correct functional claw trimming (sole horn thickness 5 mm; group 1) and on further 80 hindclaws a standardised, incorrect claw trimming (sole horn thickness 2 mm; group 2) was performed using 4 different disks (one cutting, three grinding disks). Two thermocouples were inserted into the solar corium and the heat production on the corium was measured during claw trimming. During correct functional claw trimming with each of the 4 disks a temperature increase in the corium with a median of < or = 0.3 degrees C was calculated. During incorrect claw trimming (2 mm sole horn thickness) a temperature increase with a median of < or = 0.3 degrees C for the first three disks was determined. During claw trimming using the abrasive semiflexible plastic disk a median of 1.3 degrees C temperature increase was calculated. Comparison of the temperatures measured in the claws from group 1 and 2 showed a statistically significant difference between all four disks. Comparison of the temperature increase within each group (group 1 and 2) revealed a statistically significant difference between the cutting disk with steel blades and the abrasive, semiflexible plastic disk in both groups. The highest temperatures measured were 41.5 degrees C in group 1 using the disk with 70% amount of fitted hard metal granulate, and 42.2 degrees C in group 2 (temperature increase of 10.6 degrees C) using the abrasive semiflexible plastic disk. Under the experimental conditions of this study, only a very slight thermogenesis was found when a functional and correct claw trimming using the 4 tested disks was performed. This slight thermogenesis should not be able to cause thermic injury of the corium. By trimming the sole horn incorrectly (2 mm) the measured heat generation in the corium was minor, without danger of thermic insult, excepted for using the disk with a 70% amount of fitted hard metal granulate and the abrasive semiflexible plastic disk.

    Bovine in vitro embryo production (IVP) following Ovum Pick Up (OPU) is all too often hampered by a large time gap between the harvest of oocytes of the first and last OPU session of the day. Immediately after retrieval, oocyte maturation is initiated, resulting in oocytes maturing at different time points which necessitates laborious scheduling of the IVP process. In this study, the potential of a commercial embryo holding medium (EHM; Syngro, Bioniche Inc.) to hold immature bovine oocytes was validated. We assessed the effect of holding time and temperature on (1) oocytes' maturation; (2) blastocyst development and quality at day 8 post insemination; and (3) blastocyst yield in small groups of oocytes/zygotes simulating OPU settings. Oocytes, harvested from slaughterhouse ovaries, were held for 6 h (either at 4 °C, room temperature [RT; 22-25 °C], or 38.5 °C), for 10 h (at 4 °C or RT), and for 14 h (only at RT) in 1 mL sterile glass osmometer tubes filled with EHM prior to standard maturation (22 h at 38.5 °C) and subsequent IVP. Results were compared with controls in which no prior holding was applied. Differences between the treated and control groups were assessed by generalized mixed-effects models and considered significant at P h in EHM at different temperatures remained at the germinal vesicle stage. Holding immature oocytes in EHM for 6 h at 38.5 °C and for 10 h at 4 °C significantly decreased maturation (57.1 ± 4.1% VS 80.9 ± 3.2% and 68.6 ± 3.5% VS 80.7 ± 2.9%; respectively), and development (11.0 ± 1.8% VS 36.2 ± 2.8% and 20.1 ± 3.3% VS 40.6 ± 4.6%) (P h at RT, did not affect the maturation rates (83.2 ± 2.9% and 78.9 ± 3.2%) nor day 8 blastocyst rates (35.2 ± 2.7% and 40.2 ± 4.5%). Prolonging holding time to 14 h in RT decreased maturation and day 8 blastocyst yield (71.9 ± 3.5% VS 84.5 ± 2.7% and 25.7 ± 2.5% VS 39.5 ± 2.8%, respectively) (P h at RT. When subsequently

Calves were randomly allocated to 4 treatment groups (housed outdoors during high ambient temperature with [HAT; n = 10] or without [HAC; 4] vaccination or housed indoors in a moderate ambient temperature with [MAT; 10] or without [MAC; 4] vaccination). Rectal and nasal mucosal temperatures were recorded every 2 hours from 8 AM to 8 PM on days 0 (vaccination) and 1. Nasal swab specimens were obtained on days 0 through 7 for virus isolation. Serum samples were collected on days 0, 7, 14, and 28 for determination of antibody titers. Mean rectal temperature did not differ among the treatment groups. Mean nasal temperature for the HAT group was significantly higher than that for the MAT group at 6, 24, 30, 32, and 38 hours after vaccination. Viable IBR virus was isolated from all vaccinated calves on days 1 through 6. Two weeks after vaccination, vaccinated calves had anti-IBR antibody titers that were significantly greater than those for unvaccinated calves. Mean anti-IBR antibody titers did not differ significantly between the HAT and MAT groups. Results indicated that, following vaccination with an intranasal modified-live IBR-PI3 virus vaccine, IBR viral replication and serum antibody titers did not differ significantly between calves housed in high- and moderate-ambient temperature environments.

    Uterine arteriovenous malformation (AVM) is a rare cause of massive uterine bleeding, with 70 cases reported in the English literature. Although uterine AVM is a rare cause of menorrhagia or postmenopausal bleeding, it is important to consider in the assessment of a patient with abnormal (especially heavy) uterine bleeding because accurate diagnosis can allow appropriate treatment to be planned and avoid hysterectomy in women who wish to retain their reproductive capacity. Until relatively recently this condition was difficult to diagnose and management almost always required hysterectomy. Special investigations (hysteroscopy, Doppler flow ultrasound and pelvic angiography) are important for diagnosis and assessment. Transcatheter embolization has replaced hysterectomy as the treatment of choice in women who wish to retain their fertility. Curettage may precipitate life-threatening haemorrhage and is therefore contraindicated when uterine AVM is suspected.

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

    No quantitative or qualitative Doppler velocimetry classification of vascular flow resistance covering all stages of forward and reversed flows exists. The objective of this study was to characterize uterine artery (UtA) flow velocity waveforms (FVWs) obtained during an oxytocin challenge test (OCT) and compare them to FVWs in spontaneous normal labor. Uterine artery Doppler velocimetry was performed during and between uterine contractions in 61 high-risk pregnancies subjected to an OCT and in 20 normal pregnancies undergoing spontaneous labor. FVWs were classified relative to the presence of forward/absent/reversed flow during systole and diastole, and the time-averaged flow velocity over the heart cycle. Eleven different FVW classes were identified. No relationship between FVWs recorded during uterine inertia and contractions was found (P >/= 0.2). In both groups, only forward FVWs were recorded between contractions, whereas during contractions flow reversal was more common in the OCT group (P uterine contractions were not predicted by flow patterns recorded during uterine inertia. Reversal of flow direction was more common during oxytocin-induced uterine contractions than during spontaneous contractions. In cases of predominantly reversed flow, domains of the uterus may be supplied by blood from the contralateral UtA. These observations give new insights into the circulatory dynamics of the uterus during labor, and also point to a possible vasoconstrictory effect in the UtAs of oxytocin at high concentrations.

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

    Full Text Available Among the various systemic reactions against infection or injury, the acute phase response is the cascade of reaction and mostly coordinated by cytokines-mediated acute phase proteins (APPs production. Since APPs are sensitive innate immune molecules, they are useful for early detection of inflammation in bovines and believed to be better discriminators than routine hematological parameters. Therefore, the possibility of using APPs as a diagnostic and prognostic marker of inflammation in major bovine health disorders including postpartum uterine infection has been explored by many workers. In this review, we discussed specifically importance of postpartum uterine infection, the role of energy balance in uterine infections and potential of APPs as a predictor of postpartum uterine infections during the transition period and its regulatory mechanism in dairy cattle.

    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.

    Ulipristal acetate, a selective progesterone-receptor modulator, inhibits the proliferation and induces apoptosis of leiomyoma cells in vitro. It also modulates the expression of vascular endothelial growth factors and hormone receptors and modulates extracellular matrix breakdown in leiomyoma cells but not in myometrial cells. In two randomized, double-blind, multinational phase III trials of 13 weeks' duration in women aged 18-50 years with uterine fibroids, a once-daily regimen of oral ulipristal acetate 5 mg/day controlled excessive uterine bleeding (primary endpoint) in ≥90% of patients. Ulipristal acetate 5 mg/day was more effective than placebo and was shown to be noninferior to intramuscular leuprolide acetate 3.75 mg once monthly in controlling uterine bleeding. Uterine bleeding was rapidly controlled by ulipristal acetate. Approximately half of recipients of ulipristal acetate 5 mg/day became amenorrhoeic within the first 10 days of treatment. Furthermore, uterine bleeding was controlled significantly more rapidly for recipients of ulipristal acetate than recipients of leuprolide acetate. A significantly greater median reduction from baseline in total fibroid volume was observed for recipients of ulipristal acetate 5 mg once daily than recipients of placebo following 13 weeks' treatment (coprimary endpoint). For patients who did not undergo surgery, the volume reduction was maintained for at least 6 months after discontinuing treatment. Ulipristal acetate was generally well tolerated in women with uterine fibroids. The incidence of hot flush occurred with a significantly lower frequency for recipients of ulipristal acetate than for recipients of leuprolide acetate.

    Whitaker, Lucy; Critchley, Hilary O D

    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 OBJECTIVE: To evaluate pregnancy outcomes, complications and neonatal outcomes in women who had previously undergone uterine arterial embolization. METHODS: A retrospective study of 187 patients treated with uterine arterial embolization for symptomatic uterine fibroids between 2005-2008 was performed. Uterine arterial embolization was performed using polyvinyl alcohol particles (500-900 mm in diameter. Pregnancies were identified using screening questionnaires and the study database. RESULTS: There were 15 spontaneous pregnancies. Of these, 12.5% were miscarriages (n = 2, and 87.5% were successful live births (n = 14. The gestation time for the pregnancies with successful live births ranged from 36 to 39.2 weeks. The mean time between embolization and conception was 23.8 months (range, 5-54. One of the pregnancies resulted in twins. The newborn weights (n = 14 ranged from 2.260 to 3.605 kg (mean, 3.072 kg. One (7.1% was considered to have a low birth weight (2.260 kg. There were two cases of placenta accreta (12.5%, treated with hysterectomy in one case [6.3%], one case of premature rupture of the membranes (PRM (6.3%, and one case of preeclampsia (6.3%. All of the patients were delivered via Cesarean section. CONCLUSION: In this study, there was an increased risk of Cesarean delivery. There were no other major obstetric risks, suggesting that pregnancy after uterine arterial embolization is possible without significant morbidity or mortality.

    Background Uterine fibroids are the most common non-malignant growths in women of childbearing age. They are associated with heavy menstrual bleeding and subfertility. Herbal preparations are commonly used as alternatives to surgical procedures. Objectives To assess the benefits and risks of herbal preparations for uterine fibroids. Search strategy Authors searched following electronic databases: the Trials Registers of the Cochrane Menstrual Disorders and Subfertility Group and the Cochrane Complementary Medicine Field, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2008, Issue 3), MEDLINE, EMBASE, the Chinese Biomedical Database, the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS), AMED, and LILACS. The searches ended on 31st December 2008. Selection criteria Randomised controlled trials comparing herbal preparations with no intervention, placebo, medical treatment or surgical procedures in women with uterine fibroids. We also included trials of herbal preparations with or without conventional therapy. Data collection and analysis Two review authors collected data independently. We assessed trial risk of bias according to our methodological criteria. We presented dichotomous data as risk ratios (RR) and continuous outcomes as mean difference (MD), both with 95% confidence intervals (CI). Main results We included two randomised trials (involved 150 women) with clear description of randomisation methods. The methodological risk of bias of the trials varied. There were variations in the tested herbal preparations, and the treatment duration was six months. The outcomes available were not the primary outcomes selected for this review, such as symptom relief or the need for surgical treatment; trials mainly reported outcomes in terms of shrinkage of the fibroids. Compared with mifepristone, Huoxue Sanjie decoction showed no significant difference in the disappearance of uterine fibroids, number of

    2017-06-01

    Full Text Available Reproductive inefficiency in cattle has major impacts on overall productivity of cattle operations, increasing cost of production, and impacting the sustainability of the cattle enterprise. Decreased reproductive success and associated disease states have been correlated with the presence of specific microbes and microbial community profiles, yet details of the relationship between microbial communities and host physiology are not well known. The present study profiles and compares the microbial communities in the bovine uterus and vagina using 16S rRNA sequencing of the V1–V3 hypervariable region at the time of artificial insemination. Significant differences (p < 0.05 between the vaginal and uterine communities were observed at the level of α-diversity metrics, including Chao1, Shannon’s Diversity Index, and observed OTU. Greater clustering of vaginal OTU was apparent in principal coordinate analysis compared to uterine OTU, despite greater diversity in the vaginal community in both weighted and unweighted UniFrac distance matrices (p < 0.05. There was a significantly greater relative abundance of unassigned taxa in the uterus (p = 0.008, otherwise there were few differences between the overall community profiles. Both vaginal and uterine communities were dominated by Firmicutes, although the relative abundance of rRNA sequences corresponding to species in this phylum was significantly (p = 0.007 lower in the uterine community. Additional differences were observed at the genus level, specifically in abundances within Clostridium (p = 0.009, Anaerofustis (p = 0.018, Atopobium (p = 0.035, Oscillospira (p = 0.035, 5-7N15 (p = 0.035, Mycoplasma (p = 0.035, Odoribacter (p = 0.042, and within the families Clostridiaceae (p = 0.006, Alcaligenaceae (p = 0.021, and Ruminococcaceae (p = 0.021.

    Uterine cancer is the most common pelvic gynecological malignancy. Uterine sarcomas and relapsed uterine carcinomas have limited treatment options. The search for new therapies is urgent. Dendritic cell (DC) immunotherapy holds much promise, though has been poorly explored in uterine cancer. This commentary gives an insight in existing DC immunotherapy studies in uterine cancer and summarizes the possibilities and the importance of the loading of tumor antigens onto DC and their subsequent maturation. However, the sole application of DC immunotherapy to target uterine cancer will be insufficient because of tumor-induced immunosuppression, which will hamper the establishment of an effective anti-tumor immune response. The authors give an overview on the limited existing immunosuppressive data and propose a novel approach on DC immunotherapy in uterine cancer.

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

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

    2016-02-01

    Full Text Available With the development of gynecologic laparoscopy technology in recent years, uterine artery occlusion by laparoscopy (UAOL has become a primary treatment for symptomatic uterine fibroids. Uterine artery occlusion by laparoscopy to treat uterine fibroids has favorable clinical outcomes such as relieving menometrorrhagia, decreasing uterine volume, and reducing the recurrence rate of fibroids. However, the therapeutic mechanism of UAOL remains unclear. It may be that the mechanism of UAOL is mostly associated with the uterine blood supply and uterine intramural arterial paths and with the difference between the uterine myometrium and fibroid tissues in the coagulation–fibrinolysis system. Therefore, this study reviewed and generalized many documents on the clinical effects and therapeutic mechanism of UAOL.

    Feline endometrial adenocarcinomas are uncommon malignant neoplasms that have been poorly characterized to date. In this study, we describe a uterine adenocarcinoma in a Persian cat with feline leukemia virus infection. At the time of presentation, the cat, a female Persian chinchilla, was 2 years old. The cat underwent surgical ovariohystectomy. A cross-section of the uterine wall revealed a thickened uterine horn. The cat tested positive for feline leukemia virus as detected by polymerase chain reaction. Histopathological examination revealed uterine adenocarcinoma that had metastasized to the omentum, resulting in thickening and the formation of inflammatory lesions. Based on the histopathological findings, this case was diagnosed as a uterine adenocarcinoma with abdominal metastasis. To the best of our knowledge, this is the first report of a uterine adenocarcinoma with feline leukemia virus infection.

    Full Text Available Uterine fibroids (leiomyoma, the benign tumors of the uterine wall, are very common cause of morbidity in reproductive age women usually in the form of excessive vaginal bleeding, chronic pelvic pain, miscarriage and infertility. These tumors are the leading indication for hysterectomy in the United States. Uterine fibroids are about 4 times higher in blacks compared to whites and constitute a major health disparity challenge. The estimated cost of uterine fibroids is up to $34.4 billion annually. Additionally, women who suffer from this disease and desire to maintain their future fertility have very limited treatment choices. Currently, there is no effective long-term medicinal treatment for uterine fibroids. While surgery has traditionally been the gold standard for the treatment of uterine fibroids, there is growing interest towards orally administered medications for the management of leiomyoma-related symptoms. In this paper, we will discuss these promising innovative oral medical treatments in detail.

    The etiology of uterine leiomyoma (or fibroids) is poorly understood. Sex steroid hormones and growth factors have been hypothesized to play a role in their development, and anthropometric characteristics may influence uterine leiomyoma risk. We analyzed prospectively-collected data from the Nurses' Health Study II, a cohort of 116,609 female registered nurses age 25 to 42 years at baseline. Incidence of uterine leiomyoma and anthropometric characteristics were assessed every 2 years. We calculated hazard ratios and 95% confidence intervals adjusted for known and suspected risk factors for uterine leiomyoma. Uterine leiomyomas were associated with current body mass index, change in weight since age 18, and waist-to-hip ratio. However, there was little evidence of their association with body mass index at age 18, childhood or adolescent body size, or adult height. Body mass and weight gain in adulthood may increase the risk of uterine leiomyoma, but body mass in early life does not.

    Full Text Available Uterine leiomyosarcomas (LMS are rare tumors typically presenting rapid growth and unfavorable outcome. Nowadays the results of uterine LMS treatment do not meet expectations. Angiogenesis is one of processes investigated to be target for future treatment. The aim of the research was to assess microvessels density (MVD in tumor samples collected from 50 patients with histological confirmed uterine leiomyosarcoma and to investigate statistical relations between MVD, patients survival, and FIGO stage of tumor. The assessment was carried out using immunohistochemistry methods with anti-CD34 antibody. No significant difference in MVD between FIGO stages was observed. Furthermore, contrary to many other malignancies, we found no significant relation between MVD and patients overall and 2-year survival. Results obtained in the study suggest that processes on vascular mimicry and mesenchymal to epithelial transition (MET may play important role in development of LMS. No statistical relation between MVD and survival leads to conclusion that not only angiogenesis but other mechanisms as well should be taken into consideration in planning future research.

    Emilio A Martinez

    Full Text Available Excellent fertility and prolificacy have been reported after non-surgical deep uterine transfers of fresh in vivo-derived porcine embryos. Unfortunately, when this technology is used with vitrified embryos, the reproductive performance of recipients is low. For this reason and because the embryos must be stored until they are transferred to the recipient farms, we evaluated the potential application of non-surgical deep uterine transfers with in vivo-derived morulae cultured for 24 h in liquid stage. In Experiment 1, two temperatures (25 °C and 37 °C and two media (one fully defined and one semi-defined were assessed. Morulae cultured in culture medium supplemented with bovine serum albumin and fetal calf serum at 38.5 °C in 5% CO2 in air were used as controls. Irrespective of medium, the embryo viability after 24 h of culture was negatively affected (P<0.05 at 25 °C but not at 37 °C compared with the controls. Embryo development was delayed in all experimental groups compared with the control group (P<0.001. Most of the embryos (95.7% cultured at 37 °C achieved the full or expanded blastocyst stage, and unlike the controls, none of them hatched at the end of culture. In Experiment 2, 785 morulae were cultured in the defined medium at 37 °C for 24 h, and the resulting blastocysts were transferred to the recipients (n = 24. Uncultured embryos collected at the blastocyst stage (n = 750 were directly transferred to the recipients and used as controls (n = 25. No differences in farrowing rates (91.7% and 92.0% or litter sizes (9.0 ± 0.6 and 9.4 ± 0.8 were observed between the groups. This study demonstrated, for the first time, that high reproductive performance can be achieved after non-surgical deep uterine transfers with short-term cultured morulae in a defined medium, which opens new possibilities for the sanitary, safe national and international trade of porcine embryos and the commercial use of embryo transfer in pigs.

    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.

    Acute and chronic renal failure secondary to bilateral severe hydroureteronephrosis is a rare sequela of uterine prolapse. We report a case of neglected complete uterine prolapse in a 72-year-old patient resulting in bilateral hydroureter, hydronephrosis, and chronic renal failure. In an attempt to diminish the ureteral obstruction a vaginal pessary was used to reduce the uterine prolapse. Finally, surgical repair of prolapse by means of a vaginal hysterectomy was performed. In conclusion, all patients presenting with complete uterine prolapse should be screened to exclude urinary tract obstruction. If present, obstructive uropathy should be relieved by the reduction or repair of the prolapse before irreversible renal damage occurs.

    Two experimental parainfluenza type 3 virus (PI3V) challenge studies were undertaken to evaluate the efficacy of a single intranasal dose of an attenuated live vaccine containing modified live bovine respiratory syncytial virus (BRSV) and temperature-sensitive PI3V in 3-week-old calves. In the first study, vaccine efficacy was evaluated in colostrum deprived calves. Nasal shedding of PI3V was highly significantly reduced in vaccinated calves challenged 10 days or 21 days after vaccination. In the second study, vaccine efficacy was assessed in calves with maternal antibodies against PI3V by challenge 66 days post-vaccination. Vaccination also significantly reduced PI3V excretion after challenge in this study. In both studies, clinical signs after challenge were very mild and were not different between vaccinated and control calves.

    The incidence of uterine arteriovenous malformation (AVM) is rare. However, it is clinically significant in that it can cause life-threatening vaginal bleeding. We report a case of a large uterine AVM with positive serum beta-human chorionic gonadotropin. A presumptive diagnosis was made; a uterine AVM accompanied by, early pregnancy or retained product of conception. Because this uterine AVM was extensive, transcatheter arterial embolization of both uterine arteries and extra-uterine feeding arteries was performed. Three months after undergoing transcatheter arterial embolization, complete resolution of the uterine AVM was confirmed without major complication.

    Uterine arteriovenous malformation (AVM) is generally associated with uterine trauma such as dilatation and curettage, therapeutic abortion, uterine surgery and uterine malignant tumors(1)). Uterine artery embolization (UAE) is performed on patients with uterine AVM who have desire for future pregnancy(2)). Some successful pregnancies were reported after UAE for uterine AVM(5,6)), however complication during pregnancy has not been described clearly. We herein for the first time report two cases of successful pregnancy and spontaneous delivery after UAE for uterine AVM who had placenta accreta and placental abruption respectively. Although successful pregnancy is possible after UAE for AVM, placenta abnormalities have to be considered during pregnancy and after delivery.

    The aim is to evaluate the efficacy of poloxamer/alginate/CaCl 2 mixture (PACM) solution/gel and hyaluronic acid/carboxymethylcellulose (HA-CMC) solution for reducing pelvic adhesion in a rat uterine horn model. A total of 48 females, Sprague Dawley rats, were divided into three groups according to the applied materials. A uterine horn adhesion model was created. The control group (group CO; n = 16) received no special materials except saline infusion. The experimental groups were treated with 1.0 mL HA-CMC solution (group HA-CMC; n = 16) or 1.0 mL PACM solution/gel (group PACM; n = 16). Adhesion scores were evaluated with macroscopic, microscopic, and immunohistochemistry grading 14 days postoperatively. Macroscopic adhesion scores, including extent, severity, and total scores in group HA-CMC and group PACM, were significantly lower than those in group CO (P < .001). Among these three categories of scoring, group PACM had a significantly lower score than did group HA-CMC in adhesion severity (P = .025). In the microscopic adhesion score analysis, the fibrosis scores in group HA-CMC and group PACM were also significantly lower than that of group CO. In group PACM, the fibrosis score was significantly lower than that of group HA-CMC. There were no statistical differences across all three groups in the microscopic inflammation and immunohistochemistry staining. Both HA-CMC solution and PACM solution/gel effectively reduced adhesion formation. PACM solution/gel was superior to HA-CMC solution in preventing pelvic adhesion, especially in adhesion severity and microscopic fibrosis.

    2007-09-01

    Uterine arteriovenous malformation (AVM) is a rare but potentially life-threatening source of bleeding. A high index of suspicion and accurate diagnosis of the condition in a timely manor are essential because instrumentation that is often used for other sources of uterine bleeding can lead to massive hemorrhage. Although angiography remains the gold standard for diagnosis, ultrasound (US) and magnetic resonance imaging (MRI) are the modalities of choice for the evaluation of a suspected AVM. US and MRI cannot only accurately define a uterine AVM, but they also have the ability to assess the extent of pelvic involvement noninvasively. The definitive treatment of uterine AVM is hysterectomy. However, most women diagnosed with the condition are of childbearing age. Transcatheter uterine artery embolization offers a safe and effective alternative to surgery, with the major advantage of retaining childbearing capacity.

    2014-01-01

    To obtain quantitative data on uterine contractility postpartum and compare the response of intramuscular oxytocin to carbetocin. A prospective study using an intrauterine pressure transducer (IUPT) to measure frequency, amplitude, and duration of contractions following the administration of either oxytocin (10 U) or carbetocin (30 microg). The IUPT was tolerated by all subjects and generated useful data 90% of the time in most subjects (12/16). Both drugs generated hypertonic uterine activity with contractions of similar duration. However, carbetocin resulted in contractions of sustained higher amplitude and frequency and therefore higher uterine performance as expressed by Montevideo units. This uterotonic effect of carbetocin lasted for 3 hours. IUPT monitoring generated quantitative data on postpartum uterine activity. When compared to high-dose oxytocin, a low dose of carbetocin has a more prolonged effect on uterine activity both in terms of a higher amplitude and frequency of contractions.

  7. Clinical assessment of uterine contractions.

    Science.gov (United States)

    Cohen, Wayne R

    2017-11-01

    The assessment of uterine contractions is important in clinical decision-making, but the precise role for appraising contractions remains controversial. Four clinical approaches to assessing contractions are available: manual palpation; intrauterine pressure determination; external tocodynamometry; and electrohysterography. Palpation is inexpensive and harmless but requires the constant bedside presence of a trained observer. Intrauterine pressure measurement is considered the most sensitive and specific technique, and has become the standard by which other methods are judged; however, its quantitative measurements are not always precise or reproducible. Moreover, the availability of intrauterine pressure measurements does not seem to improve maternal or neonatal outcomes in most situations. External tocodynamometry is the most widely used technique. It is easy to apply and provides reasonably accurate information about the frequency and duration of contractions, but not their amplitude. It can require frequent adjustment during labor and might not work well in patients who are obese. Electrohysterography is a recently available noninvasive technology that detects uterine electrical activity using electrodes placed on the mother's abdominal wall. This approach is at least as reliable and accurate as tocodynamometry. © 2017 International Federation of Gynecology and Obstetrics.

    Endometrial ablation has gained significant clinical acceptance over the last decade as a minimally invasive treatment for abnormal uterine bleeding. To improve upon current thermal injury modeling, it is important to better characterize the myometrium's thermotolerance. The extent of myometrial thermal injury was determined across a spectrum of thermal histories/doses (time-temperature combinations). Fresh extirpated human myometrium was obtained from 13 subjects who underwent a previous scheduled benign hysterectomy. Within two hours of hysterectomy, the unfixed myometrium was treated in a stabilized saline bath with temperatures ranging from 45-70 °C and time intervals from 30- 150 seconds. The time-temperature combinations were selected to simulate treatment times under 2.5 minutes. A total of six such thermal matrices, each comprised of 45 time-temperature combinations, were prepared for evaluation. The treated myometrium was cryosectioned for nitro blue tetrazolium (NBT) staining to assess for thermal respiratory enzyme inactivation. Image analysis was subsequently used to quantitatively assess the stained myometrium's capacity to metabolize the tetrazolium at each time-temperature combination. This colorimetric data was then used as marker of cellular viability and determine survival parameters with implications for developing minimally invasive uterine therapies.

    Leiomyomas are the most common benign uterine tumor; however, this entity is relatively uncommon in the pediatric population. Although leiomyomas most commonly present as solitary uterine masses, unusual patterns of growth have been described including diffuse leiomyomatosis. In this condition, the myometrium of the uterus is symmetrically expanded by innumerable confluent leiomyomas; this pattern of growth is quite uncommon and has never been reported in a pediatric patient. This case report illustrates the imaging appearance of diffuse uterine leiomyomatosis in an otherwise healthy 16-year-old girl. (orig.)

    A rare case of giant uterine lymphangioma was experienced. A 44-year-old female noted a rapidly grown abdominal tumor and its accompanied symptoms, progressive abdominal distension, lumbago, and developed leg edema. Ultrasonography made a possible diagnosis of a huge ovarian tumor; postoperative diagnosis was cavernous lymphangioma arising from the uterus. According to the literature, lymphangioma itself is a rare tumor, and giant lymphangioma arising from uterine corpus is extremely rare. We experienced an extremely rare case of uterine lymphangioma and ultrasound tomography better imaged the tumor inside.

    To evaluate the success rate and possible complications of the B-Lynch uterine compression sutures in women who suffered from postpartum uterine atony unresponsive to medical treatment. A total of 36 women who were managed with the B-Lynch suture, with or without additional surgical procedures following uterine atony unresponsive to medical treatment, were evaluated retrospectively. Sixteen women were primarily managed with the B-Lynch compression sutures, and 11 women had the B-Lynch compression sutures following failure of achievement of hemostasis by ligation of uterine artery alone (n = 4), or uterine artery plus uterine branch of ovarian artery (n = 7). Eight women had bilateral internal iliac artery ligation (BIIAL) following failure of achievement of hemostasis by the B-Lynch compression sutures. Two women (5.5%) underwent post-cesarean hysterectomy. The overall success rate of B-Lynch was 75% (27/36), and the overall success rate of B-Lynch plus BIIAL was 94.4% (34/36). Three women were admitted to the intensive care unit. There was no death related to the hemorrhage in our series. No short-term complications such as uterine necrosis, hematometra, pyometra, or uterine erosion related to the uterine compression suture were observed. Overall success rate of the B-Lynch sutures and B-Lynch sutures plus BIIAL was 75 and 94.4%, respectively. The B-Lynch technique does not necessarily require specific suture material. Uterine devascularization or BIIAL did not increase the risk of the possible short-term complications such as uterine necrosis. In case of failure of the B-Lynch uterine compression sutures, BIIAL may be beneficial to save the uterus.

    Uterine arteriovenous malformation (AVM) is a rare and potentially life-threatening disease. The present report describes a postmenopausal patient with uterine AVM manifesting recurrent, massive genital bleeding. Uterine artery embolization (UAE) was scheduled before hysterectomy, but UAE was unsuccessful due to the dilated, tortuous internal iliac arteries, and extremely rapid arterial blood flow. Hysterectomy appeared to carry a potential risk of massive blood loss due to multiple dilated vessels around the uterine corpus and cervix. Therefore, six arteries feeding the uterus were surgically ligated. At 10 months after the operation there have been no episodes of atypical genital bleeding.

    The prevalence of obstructive uropathy linked to uterine prolapse ranges between 4% and 80%, depending on the series, probably due to the varying degree of severity of the prolapses under consideration. Renal failure or anuria is an unusual complication. Several etiopathogenic theories regarding obstructive uropathy secondary to prolapse have been put forward: ureteral compression by the uterine vessels, severe urethral angulation, ureteral compression against levator ani muscles and the elongation and narrowing of the distal ureter. The major radiological exploration used in studying the urinary tract of these patients is intravenous urography in bipedestation. Emergency treatment for obstructive anuria resulting from a uterine prolapse consists of manually replacement of the prolapse. Surgery is considered to be the definitive ideal treatment, although in the case of surgical or anaesthetic high risk patients, inserting a permanent pessary may constitute a satisfactory solution. We present a case of obstructive anuria resulting from uterine prolapse, which was successfully treated with the insertion of a ring pessary.

    Uterine arteriovenous malformation (AVM) is an infrequently described cause of severe genital tract bleeding. This is an important diagnostic consideration as therapeutic options differ significantly from those utilized with alternate etiologies of genital tract bleeding. A 30-year-old multiparous female presented initially with vaginal bleeding, and subsequently with intra-abdominal hemorrhage. She was diagnosed with uterine AVM, and was managed with uterine artery embolization followed by eventual hysterectomy. AVMs, both congenital and acquired, are diagnosed utilizing a range of radiographic tools. Management modalities include embolization and hysterectomy. Our patient presented uniquely with intra-abdominal hemorrhage. Previously managed with uterine artery embolization, hysterectomy became necessary because of her clinical presentation.

    Transarterial embolization is an established treatment for uterine arteriovenous malformation (AVM); however, in some cases, transarterial embolization is difficult. We present balloon-occluded retrograde transvenous obliteration as an alternative endovascular treatment for uterine AVM. A 24-year-old woman was diagnosed with uterine AVM. Her medical treatments were ineffective, and selective embolization was abandoned because of the extremely tortuous feeders. We used balloon-occluded retrograde transvenous obliteration, in which balloon catheters were inserted into the draining vein to stop the outflow. Then, a sclerosant was retrogradely injected through the catheter into the nidus. The abnormal vessels were fully obliterated, and there was no recurrence after the treatment. Balloon-occluded retrograde transvenous obliteration may be an alternative treatment for uterine AVMs with adequate vascular structures.

    The present study demonstrates the presence of the endogenous opioid peptides beta-endorphin (beta-EP) and methionine-enkephalin (MET-ENK), in the uterine fluid of fertile women and normally cycling and superovulated cows. The two peptides are undetectable in the uterine fluid of untreated postmenopausal women, whereas they are present following estrogen-progesterone treatment. Immunoreactive (IR) MET-ENK concentrations were higher in the secretory than in the proliferative phase of the menstrual cycle. IR beta-EP and IR MET-ENK are present also in the follicular, oviductal, and uterine fluid of cows, and in the uterine fluid, concentrations of IR MET-ENK are higher in the superovulated than in the control animals. Because opioids play important roles on endocrine and immune functions, the present data support the potential physiologic role of endometrial secretions.

    The objective of the study was to review all patient records discharged with codes for uterine rupture in 2006 in Hospital Corporation of America hospitals. All patient charts were distributed to a committee of perinatologists and general obstetricians. Case report forms were analyzed for variables of interest to determine validity of coding and quality of care. Of 69 cases identified, only 41 were true ruptures. Twenty patients had previous cesareans, and in 9 of these patients, concurrent use of oxytocics was documented. Among the 21 patients without previous cesareans, 7 had previous uterine surgery, and oxytocics were documented in 12 of the remaining 14 patients. Standard of care violations were identified in 10 of 41 true rupture cases. Epidemiological data on uterine rupture based on hospital discharge codes without concurrent chart review may be invalid. Patients with previous cesareans represent only half of true uterine ruptures in contemporary practice.

    Full Text Available Background: Dysfunctional uterine bleeding is a form of abnormal uterine bleeding when there is absence of organic disease of the genital tract. The objective of this study was to find out the clinical and pathological aspect of women presenting with dysfunctional uterine bleeding.Materials and Methods: A descriptive study was conducted over a period of one year from April 14th 2010 to April 13th 2011 in the Department of Obstetrics and Gynaecology and Department of Pathology, Tribhuvan University Teaching Hospital, Kathmandu, Nepal. A complete history, clinical examination, pelvic scan, hormonal status if required and endometrial biopsy were done to diagnose dysfunctional uterine bleeding.Results: A total of 120 cases were included. The age of the patients diagnosed dysfunctional uterine bleeding were ranging from 24 -63 years. Dysfunctional uterine bleeding was most common in the age group 40-44 yrs (30% followed by 45-49 yrs (27.5%. Menorrhagia (41.7% was the most common presenting sign. Majority histopathology of endometrium revealed anovulatory pattern (61.7% followed by ovulatory (38.3%. Of the cases with an anovulatory pattern 48.6% was proliferative endometrium, 33.8% disordered proliferative endometrium, 6.8%atrophic, 5.4% weakly proliferative and 2.7% each of simple hyperplasia without atypia and complex hyperplasia with atypia. All cases with ovulatory pattern showed secretory endometrium.Conclusion: Dysfunctional uterine bleeding was the most common in the perimenopausal age group and chiefly in the form of an anovulatory endometrium. . Histopathological evaluation of endometrium helps exclude the local causes and establishes the diagnosis of dysfunctional uterine bleeding, its types, and clinical correlation to histopathological findings and finally helps to determine the mode of management.DOI: http://dx.doi.org/10.3126/jpn.v4i8.11500 Journal of Pathology of Nepal; Vol.4,No. 8 (2014 635-638

    Although the incidence of uterine disorders in pet rabbits is high there are only a few retrospective studies and case reports on genital tract disease in female rabbits. Uterine disorders were assessed in 50 pet rabbits. In 31 pet rabbits with suspected clinical uterine disease, medical records were further reviewed regarding clinical signs, diagnostic workup, treatment as well as the outcome itself. Uterine adenocarcinoma (54%) was most frequently diagnosed, followed by endometrial hyperplasia (26%). Serosanguineous vaginal discharge was the predominant clinical sign observed by the rabbit owners. In approximately 50% of the rabbits with suspected uterine disorders, abdominal palpation revealed enlarged and/or irregular masses in the caudoventral abdomen indicating uterine lesions. Out of 23 rabbits undergoing ovariohysterectomy, four were either euthanized or died shortly after surgery because they were clinically unstable. Overall, 80% of the ovariohysterectomized animals were still alive 6 mo after surgery. In female pet rabbits that are not breeding, either ovariohysterectomy should be performed at an early age or routine checks including ultrasonography of the abdomen are recommended on a regular basis.

    Liquid nitrogen preservation in remote farms is a limitation. The goal of this study was to determine optimum temperature above freezing point for bovine spermatozoa preservation using bovine serum albumin (BSA) as a supplementation. Pooled semen sample from three ejaculates was subjected to various BSA concentration (1, 4, 8 and 12 mg ml(-1)), before incubation in different above freezing point temperatures (4, 25 and 37 °C). Viability assessment was carried out against time from day 0 (fresh sample) until all spermatozoa become nonviable. Optimal condition for bovine spermatozoa storage was at 4 °C with 1 mg ml(-1) BSA for almost 7 days. BSA improved bovine spermatozoa viability declining rate to 44.28% at day 4 and 57.59% at day 7 compared to control, with 80.54% and 98.57% at day 4 and 7 respectively. Increase in BSA concentration did not improve sperm viability. Our results also confirmed that there was a strong negative correlation between media osmolarity and bovine spermatozoa survival rate with r = 0.885, P freezing point. © 2011 Blackwell Verlag GmbH.

    The maintaining of the epididymis at lower temperatures during storage and transport improves sperm quality. Our study aimed to test whether epididymis storage temperature (post-mortem) and sperm cryopreservation affect sperm kinetics, membrane integrity, mitochondrial potential and fertility capacity. Thirty-six epididymides were collected from 18 bulls after slaughter and divided into two groups: at 4 or 34°C for 2-3 hr. The sperm was collected from the epididymis cauda. The evaluation consisted of computer-assisted sperm analysis (CASA), SYBR14/PI/JC1 to evaluate membrane integrity, mitochondrial membrane potential (MMP) and measurement of lipid peroxidation (TBARS). The sperm was then frozen using an automatic device. After thawing, sperm samples were evaluated by the same variables and further in vitro fertilization rates. Cryopreservation negatively affected sperm motility in samples stored at 4 and 34°C. Nevertheless, the 4°C samples yielded higher rates of blastocyst formation. Pre-freeze sperm motility, progressive motility and velocity were higher in sperm from epididymis stored at 4°C while post-thaw sperm motility, progressive motility and velocity remained the same among samples from epididymis stored at 4 or 34°C. However, with regard to the kinetic patterns, samples collected from epididymis stored at 34°C had lower values when compared to those stored at 4°C prior the cryopreservation process. Our results indicate that epididymis handling conditions after cryopreservation may affect sperm quality after thawing, especially due to compromised MMP in sperm collected from epididymis stored at higher temperatures. © 2016 Blackwell Verlag GmbH.

    A 7-yr-old African wild dog (Lycaon pictus) multiparous bitch experienced severe dystocia and death one day after the onset of parturition. Necropsy revealed three placental attachments in the right uterine horn and one in the left. A full-thickness rupture of the right horn at the middle placental attachment and an autolysed fetus free in the abdomen were present. Death was attributed to hypovolemic and endotoxemic shock after uterine rupture. Myometrium adjacent to the rupture and in the left uterine horn was subdivided into irregular pseudolobules by fibrous connective tissue tracts containing small endometrial glandular acini suggestive of adenomyosis, which may have facilitated uterine rupture. This is the first reported case of dystocia-induced uterine rupture and of adenomyosis in a wild dog.

    2016-08-01

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

    Do the amino acid levels of human uterine fluid vary with age, BMI, phase of menstrual cycle, benign pathology or diet? The levels of 18 amino acids in human uterine fluid were shown to be affected only by maternal diet. Murine, bovine and ovine uterine amino acid content has been reported, but no reliable data on the human exist. Murine studies have demonstrated that the intrauterine periconceptional nutritional environment is affected by maternal diet. Uterine secretions were aspirated from 56 women aged 18-45 years. The women were recruited preoperatively from gynaecological theatre operating schedules or hysterosalpingo-contrast-sonography (HyCoSy) lists. A proportion of these women had proven fertility; however, the majority were being investigated for subfertility. The BMI, gynaecological history and dietary pattern of these women were also assessed. Reverse phase high performance liquid chromatography was used to analyse the concentrations of 18 amino acids within the uterine fluid and blood serum. The results were analysed against the women's stage of cycle, age, BMI and diet. The profile of 18 amino acids in uterine fluid was described. In total, human uterine fluid was observed to contain an amino acid concentration of 3.54 mM (interquartile range: 2.27-6.24 mM). The relative concentrations of 18 amino acids were not significantly altered by age, BMI, cycle phase or the presence of specific benign gynaecological pathologies. However, a diet identified by a validated scoring system as being less healthy was associated with higher concentrations of asparagine (P = 0.018), histidine (P = 0.011), serine (P = 0.033), glutamine (P = 0.049), valine (P = 0.025), phenylalanine (P = 0.019), isoleucine (P = 0.025) and leucine (P = 0.043) in the uterine fluid compared with a healthier diet, defined as one with a higher intake of fresh vegetables, fruit, whole-grain products and fish and a low intake of red and processed meat and high fat dairy products.

    The lack of uniformity in the nomenclature of the uterine sarcomas, it have contributed to a variety and variability of classifications. Fortunately the sarcomas of uterus are rare. The incidence of this tumor is of 3-5% of all the uterine cancers or of 1.7/100,000 women of 20 years or more. The clinical presentation of these tumors is diverse could come bleed uterine abnormal, abdominal pain, pelvic mass, discharge or cervix prominent mass. Clinical discoveries associated with exist the sarcomas how they are the obesity and high blood pressure in a 30% of the patients it are also observed antecedents of pelvic radiation in a 5-10% of the cases. The genomic alterations that is reported the chromosomes in the literature is associated with 1, 7 11 playing an important paper in the initiation or progression of the sarcomas. We was carried out a retrospective analysis of 37 cases of uterine sarcoma managed in the National Institute of Cancerology at one time of 5 years. Being that the leiomiosarcomas comes in the 51.3% of the cases, followed by the stromal sarcoma, bleed uterine abnormal it was the clinical fact of high importance, detecting these patients in Ia and IIa stadiums predominantly. We observed an increment in the incidence of the uterine sarcoma in patients of 40 years or more. 17 patients were managed exclusively with surgery, 17 patients with surgery and radiotherapy and 5 patients with surgery and chemotherapy (2 patients were managed with surgery + radiotherapy + chemotherapy). The index of failure was from the 45.1% to two years in general form, coming metastasic illness in lung, liver and breast mainly. In conclusion, the adjuvant radiotherapy and chemotherapy to the hysterectomy doesn't increase the index of survivor in the several subtype of uterine sarcomas.

  15. Enzootic bovine leucosis.

    Tyler, L

    1978-09-02

    Enzootic bovine leucosis is associated with infection by bovine leucosis virus. The incubation period is measured in years and a minority of infected animals develop clinical signs. The disease is widespread in Europe and elsewhere and can cause significant economic loss. The epidemiology is incompletely understood and findings from one cattle production system may not be directly applicable to another. Major control programmes exist in Denmark and West Germany and control schemes are being developed elsewhere. Eradication of enzootic bovine leucosis has been established as a goal in the EEC and research is revealing the ways in which this goal may be attained. To be effective, control and epidemiological monitoring must be interactive. Recently introduced serological tests, of improved sensitivity, provide a valuable tool.

    The purpose of this study was to describe the sonographic features of uterine arteriovenous malformations (AVMs) and to describe the role and clinical outcome after transcatheter arterial embolization of symptomatic uterine AVMs. In our institution, over a 4-year period, symptomatic uterine AVMs were diagnosed in 21 women. Endovaginal sonography with gray scale, color, and spectral Doppler imaging was performed on all patients. Fourteen patients required therapeutic angiography/embolization to control bleeding. These 14 patients had follow-up endovaginal sonography 24 hours after the procedure. The sonographic gray scale findings of uterine AVMs were nonspecific. The most common finding was subtle myometrial heterogeneity (n = 14), whereas other patients had small anechoic spaces in the myometrium (n = 7). Color Doppler sonography showed a tangle of vessels with multidirectional high-velocity flow that produced a "color mosaic" pattern. Spectral Doppler analysis showed arteriovenous shunting with high-velocity, low-resistance flow. Fourteen patients required transcatheter arterial embolization to control bleeding. Thirteen of 14 patients had no sonographic evidence of a residual AVM 24 hours after the procedure. One of 14 patients had a residual AVM requiring additional embolization. One patient had recurrent bleeding at 4 months and required further embolization. The remaining 7 patients were treated conservatively. Endovaginal sonography is the imaging modality of choice in patients with abnormal uterine bleeding. Routine use of color and spectral Doppler sonography allows one to confidently make the correct diagnosis. Transcatheter arterial embolization is an excellent treatment option. Endovaginal sonography should be used to monitor postembolization outcomes.

  17. Uterine biology in pigs and sheep

    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.

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

  19. Postpartum Prolapsed Leiomyoma with Uterine Inversion Managed by Vaginal Hysterectomy

    2014-01-01

    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.

    We aimed to evaluate the performance of a non-invasive EMG electrical uterine monitor (EUM) versus tocodynamometry (TOCO) by comparing both to internal uterine pressure catheter (IUPC). Prospective observational trial. Uterine activity was recorded continuously and simultaneously, in women during active term labor, with TOCO, EUM and IUPC. Uterine activity tracings were analyzed by three blinded physicians. Overall, 385 tracings from 43 women were analyzed. A similar rate of interpretable tracings between physicians was demonstrated for EUM (87%; 95% CI 80.9-92.7%) and IUPC (94.8%; 95% CI 83.4-96.3%), with a significantly lower rate for TOCO (67.5%; 95% CI 59.4-76.8%, p contraction frequency for EUM versus IUPC (0.77 ± 2.3) compared to TOCO versus IUPC (-3.34 ± 4.97). There is a high variability between the timing of TOCO contractions as compared to IUPC (4.74 ± 10.03 seconds), while a gap of 8.46 ± 4.24 seconds was detected for EUM. The sensitivity, positive predictive value and false positive rate for individual contraction identification by TOCO and EUM are 54.0%, 84.4%, 15.6% and 94.2%, 87.6%, 12.4%, respectively. EUM is efficient as IUPC for uterine activity assessment and both techniques are superior in comparison to external tocodynamometry. Our results support the use of non-invasive EMG technology to monitor uterine activity.

    In rodent models of experimentally induced fever, the important role of interleukin-6 (IL-6) as a circulating endogenous pyrogen is well established. Studies employing larger animal species and real infections are scarce. Therefore, we assessed bioactive IL-6 in peripheral blood and in broncho-alveolar lavage fluid (BALF) of calves after intra-bronchial inoculation with vital Chlamydia psittaci (Cp), with inactivated Cp, or with BGM cells. Only calves inoculated with vital Cp developed fever (peak at 2-3 days after challenge) and significantly increased IL-6 activity. Controls inoculated with either inactivated Cp or BGM cells also expressed increased bioactive IL-6, but no fever developed. Activity of IL-6 in BALF was significantly higher compared to blood serum. This experimental model of Cp infection revealed no apparent relation between IL-6 in blood and body temperature, but did reveal a relation between IL-6 and other markers of inflammation in BALF. We conclude that a local inflammatory response in the lungs of infected calves caused fever, which developed by mechanisms including other mediators besides IL-6.

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

    Full Text Available To prevent excessive bacterial growth in raw milk, the FAO recommends two options: either cold storage or activation of the lactoperoxidase system (LPs/ HT in milk with the addition of two chemical preservatives, hydrogen peroxide (H and thiocyanate (T. N2 gas flushing of raw milk has shown great potential to control bacterial growth in a temperature range of 6 to 12°C without promoting undesired side effects. Here, the effect of N2 gas (N was tested as a single treatment and in combination with the lactoperoxidase system (NHT on seven raw milk samples stored at 15 or 25°C. For the ratio defined as bacterial counts from a certain treatment/counts on the corresponding control, a classical Analyse of Variance (ANOVA was performed, followed by mean comparison with the Ryan-Einot-Gabriel-Welsch multiple range test (REGWQ. Altogether, the growth inhibition was slightly but significantly higher at 25°C than at 15°C. Except for one sample, all ratios were lower for HT than for N alone; however, these differences were not judged to be significant for five samples by the REGWQ test; in the remaining two samples, N was more effective than HT in one case and less effective in the other case. This study shows that N2 gas flushing, which inhibited bacterial growth in raw milk at 15 and 25°C for 24 and 12 h, respectively, could constitute an alternative to LPs where no cold storage facilities exist, especially as a replacement for adulterating substances.

    1984-05-01

    The relative contrast enhancement of normal myometrium and small or medium size uterine fibroids and clinical stage I endometrial carcinomas were correlated to their microangiographically demonstrable vascularity. In four cases small uterine fibroids showed contrast enhancement equal to normal myometrium, independent of their vascularity in microangiography. In five, endometrial carcinomas contrast enhancement was always below that of the surrounding myometrium in CT. Intratumour vasculature showed great variability in microangiography. No correlation between the topographic variations in the arrangement or density of tumour blood vessels and the degree of contrast enhancement was found. Contrast enhancement of small uterine fibroids was greater than that of small adenocarcinomas. More contrast material accumulates into the extravascular space of the smooth muscle tissue of the fibroid than into the extravascular space of endometrial carcinoma.

Ischemic necrosis and rupture of the uterus is a theoretical concern of this procedure. Rupture of the uterus from any cause is a very serious gynecologic complication requiring immediate surgical intervention to prevent death. Ischemic necrosis and rupture of the uterus can occur months after UAE. In our patient they occurred 3 months after UAE for treatment of symptomatic uterine myomas, and required hysterectomy. To our knowledge, this is the first report of ischemic uterine rupture after UAE in the United States.

    Postpartum uterine diseases of dairy cows compromise animal welfare and may result in early removal from the herd or impaired reproductive performance. The relationship between poor immune status around calving and uterine diseases is well established; however, that between natural antibodies (NAb) and uterine health has not yet been studied. The objective of this study was to evaluate the association of circulating NAb levels around parturition with puerperal metritis, clinical endometritis, and the intrauterine presence of the Escherichia coli virulence factor FimH. One hundred six pregnant heifers were enrolled; NAb in serum samples collected at 30 ± 3 d prepartum and at 2 ± 1 and 35 ± 3 d in milk (DIM) were measured by ELISA. Puerperal metritis was defined as the presence of fetid, watery, red-brown uterine discharge and rectal temperature >39.5°C at 6 ± 1 DIM. Clinical endometritis was defined as presence of pus in the uterine lavage sample collected at 35 ± 3 DIM. The intrauterine presence of the fimH gene at 2 ± 1 DIM was evaluated by PCR. The overall optical density (wavelength of 650 nm) of ELISA-detected serum NAb was lower for cows diagnosed with puerperal metritis than for cows that did not have puerperal metritis. Additionally, cows diagnosed with clinical endometritis tended to have lower levels of NAb than did cows without clinical endometritis. Finally, FimH-positive cows had lower overall levels of serum NAb compared with FimH-negative cows. In conclusion, NAb detected in serum around parturition was associated with uterine health of dairy cows. Copyright © 2014 American Dairy Science Association. Published by Elsevier Inc.

    In late pregnancy three different dinks of uterine activity can be observed by external tocography: Alvarez-waves, Braxton-Hicks-contractions and phases of inactivity equivalent to the intervals of labour. Contractions and phases of inactivity increases on to delivery, while the portion of Alvarez-waves decreases. Braxton-Hicks-contractions and phases of inactivity are opposed to the uncoordinated Alvarex-waves as coordinated activity. Accordingly these changes are explained as a process of increasing coordination of uterine activity, which finally ends in delivery.

    2015-09-01

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

    To evaluate the technical feasibility and clinical outcome of bilateral uterine artery embolization (UAE) as a first-line therapeutic option for bleeding uterine arteriovenous malformation (AVM). Between 2002 and 2012, 19 patients were diagnosed with acquired uterine AVM clinically and through imaging studies. The clinical characteristics, angiographic features, technical success rate of embolization, procedure-related complications, imaging, and clinical follow-up data were assessed. Clinical success was defined as immediate symptomatic resolution with disappearance of vascular abnormality on subsequent imaging studies. A total of 20 bilateral UAE, with or without embolization of extra-uterine feeders, were performed as the first-line treatment. Technical and clinical success rate was 90.0% (18/20) and 89.5% (17/19), respectively. Embolization was incomplete in two patients who had residual extra-uterine fine feeders to the AVM or a procedure- related complication (ruptured uterine artery); the former showed slow regression of the vascular malformation during the observation period, while the latter underwent a successful second bilateral UAE. Immediate clinical success was achieved in the remaining 17 patients after a single session and no recurrence of bleeding was found. Recovery to normal menstrual cycle was seen in all 17 patients with clinical success within one or two months, two of whom subsequently had uneventful intrauterine pregnancies carried to term. Bilateral UAE is a safe and effective first-line therapeutic option for the management of bleeding uterine AVMs. However, incomplete embolization due to unembolizable feeders or difficult access into the uterine artery may lead to suboptimal treatment.

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

    Full Text Available Uterine septum is associated with an increased rate of recurrent miscarriages which can be reduced significantly by performing endoscopic resection. Perinatal outcome improvement due to resection is favorable but still remains controversial. Uterine rupture is a late complication of hysteroscopic surgery that may be a life-threatening condition in terms of perinatal and maternal morbidity–mortality. This article presents the first case of the related literature dealing with the successful management of the third recurrent uterine rupture in the 31st week of pregnancy subsequent to the hysteroscopic resection of uterine septum. The patient observed in this article had experienced uterine rupture twice; firstly, in the 27th week of pregnancy resulted with postpartum exitus and secondly, in the 29th week of pregnancy that ended with stillbirth while her last pregnancy eventuated in a live healthy birth. Surgeons who accomplish these hysteroscopic procedures must weigh out pros and cons; and must also acquaint their patients with the probable risk of recurrent and multiple uterine ruptures during the subsequent pregnancy.

    Cervical incompetence is basically a cervix that is too weak to stay closed during a pregnancy. It is generally categorized as premature opening of the cervix without labor or contractions. To estimate the incidence of incompetence of the uterine cervix at patients with congenital uterine malformations. Our study was a retrospective and prospective one between 2002 and 2009. We evaluate the length of the cervix by transvaginal ultrasonography during the second trimester of pregnancy. We had 316 cases with congenital uterine malformations. From these we found 49 (15.3%) women with incompetence of the cervix: 8 (2.5%) with unicornuate uterus, 11 (3.4%) with bicornuate uterus and 30 (9.5%) cases uterus with septum. For all these wad made cerclage when we found funneling of the cervix or the cervix was open less than 4 cm. The use of ultrasonography has been very helpful with the diagnosis, and is made when the cervical os (opening) is greater than 2.5 cm, or the length has shortened to less than 20 mm. All patients had preterm delivery. When we have cases with congenital uterine malformations we must think that incompetence of the cervix could be associated, so we must assess the status of the cervix for these patients by serial ultrasound examinations starting between 16 and 20 weeks of gestation. Our patients had preterm delivery caused not only the incompetent cervix, but the malformation of the uterus is implicated also.

    Ellis, John A

    2010-11-01

    Bovine parainfluenza-3 virus (bPI(3)V) is a long-recognized, currently underappreciated, endemic infection in cattle populations. Clinical disease is most common in calves with poor passive transfer or decayed maternal antibodies. It is usually mild, consisting of fever, nasal discharge, and dry cough. Caused at least partly by local immunosuppressive effects, bPI(3)V infection is often complicated by coinfection with other respiratory viruses and bacteria, and is therefore an important component of enzootic pneumonia in calves and bovine respiratory disease complex in feedlot cattle. Active infection can be diagnosed by virus isolation from nasal swabs, or IF testing on smears made from nasal swabs. Timing of sampling is critical in obtaining definitive diagnostic test results. Parenteral and intranasal modified live vaccine combination vaccines are available. Priming early in calfhood with intranasal vaccine, followed by boosting with parenteral vaccine, may be the best immunoprophylactic approach. Copyright © 2010 Elsevier Inc. All rights reserved.

Histopathological sections showed abundant hyaline and pigmented extra and intracellular fungal structures together with a polymorphic cellular granuloma formed by neutrophils, lymphocytes, plasmocytes, histiocytes and giant cells of the Langhans type. It is the first case of mycotic bovine nasal granuloma recognized in Uruguay although this disease seems to be frequent according to the opinion of veterinarian specialists. Another similar clinical case also in a Jersey cow from the same dairy house with an intense cellular infiltrate rich in eosinophils without granulomatous image, together with extracellular hyaline and fuliginous fungal forms, is also referred for comparative purposes. Geotrichum sp. was isolated. The need of an early diagnosis and treatment of the disease is stressed.

    Full Text Available The aim of the study was to evaluate the influence of sildenafil citrate administrated intravaginaly on the blood flow in the bovine uterus during dioestrus. Uterine blood flow was examined in six healthy adult cows. Sildenafil was administrated intravaginaly to each co w between the 6th and 8th d of the ovarian cycle, in the form of vaginal suppositories containing 100 mg of active substance at a dose of 100, 200, or 300 mg per animal. Uterine perfusion was estimated by the colour Doppler examination, and obtained results were analysed with the Pixel Flux Software (Chameleon, Germany. Moreover, cardiovascular parameters were also evaluated. Animals were examined before and five times after drug application (two times at 15 min intervals, and three times at 2 h intervals. A placebo suppository was also given to the cows. The analysis of the intensity and velocity of blood flow in the uterus proved that sildenafil administrated intravaginaly significantly increased blood flow in the uterus and the effect of increased perfusion was observed for 4 h and 30 min after administration. The effect of increased uterine perfusion was observed after low as well as high doses of sildenafil. Significant changes in the cardio-vascular parameters were not detected. There were no changes in the uterine perfusion as well as in cardiovascular parameters after placebo administration.

    2002-08-02

    This review deals with the role of viruses in the aetiology of bovine mastitis. Bovine herpesvirus 1, bovine herpesvirus 4, foot-and-mouth disease virus, and parainfluenza 3 virus have been isolated from milk from cows with clinical mastitis. Intramammary inoculations of bovine herpesvirus 1 or parainfluenza 3 virus-induced clinical mastitis, while an intramammary inoculation of foot-and-mouth disease virus resulted in necrosis of the mammary gland. Subclinical mastitis has been induced after a simultaneous intramammary and intranasal inoculation of lactating cows with bovine herpesvirus 4. Bovine leukaemia virus has been detected in mammary tissue of cows with subclinical mastitis, but whether this virus was able to induce bovine mastitis has not been reported. Bovine herpesvirus 2, vaccinia, cowpox, pseudocowpox, vesicular stomatitis, foot-and-mouth disease viruses, and bovine papillomaviruses can play an indirect role in the aetiology of bovine mastitis. These viruses can induce teat lesions, for instance in the ductus papillaris, which result in a reduction of the natural defence mechanisms of the udder and indirectly in bovine mastitis due to bacterial pathogens. Bovine herpesvirus 1, bovine viral diarrhoea virus, bovine immunodeficiency virus, and bovine leukaemia virus infections may play an indirect role in bovine mastitis, due to their immunosuppressive properties. But, more research is warranted to underline their indirect role in bovine mastitis. We conclude that viral infections can play a direct or indirect role in the aetiology of bovine mastitis; therefore, their importance in the aetiology of bovine mastitis and their economical impact needs further attention.

    2012-01-01

    We used immunofluorescent confocal microscopy and scanning electron microscopy to quantify uterine vascularity and to describe uterine surface morphology during gestation in pregnant females of the lecithotrophic lizard Niveoscincus coventryi. As uterine angiogenesis and epithelial cell morphology are thought to be under progesterone control, we studied the effect of a progesterone receptor antagonist (mifepristone) on uterine and chorioallantoic microvasculature and features of the uterine epithelial surfaces. Although intussuceptive angiogenesis was observed in both, uterine and chorioallantoic, vascular beds during gestation, the only significant increases were in the diameters of the uterine vessels. An ellipsoid vessel-dense area grows in the mesometrial hemisphere of the developing conceptus, which parallels the expansion of the allantois to form the chorioallantoic placenta. Uterine surface topography changed during gestation. In particular, uterine blood vessels bulge over the luminal surface to form marked ridges on the uterine embryonic hemisphere, especially during the last stage of pregnancy, and ciliated cells are maintained in the embryonic and abembryonic hemispheres but disappear in both the mesometrial and antimesometrial poles. This distinct regionalization of uterine ridges and ciliated cells in the uterine surface and in the shape of the epithelial component of the chorion might be related to the function of both chorioallantoic and yolk sac placentae during gestation. There was no significant difference between females treated with or without mifepristone, which may be related to the partial function of mifepristone as a progestin antagonist and/or with the function and time of action of progesterone in the uterus during gestation in N. coventryi. Differences in the pattern of angiogenesis and uterine surface morphology during gestation among squamates may be related to the functional diversity of the uterine component of the different

    Although a radiographic unit is not standard equipment for bovine practitioners in hospital or field situations, ultrasound machines with 7.5-MHz linear transducers have been used in bovine reproduction for many years, and are eminently suitable for evaluation of orthopedic disorders. The goal of this article is to encourage veterinarians to use radiology and ultrasonography for the evaluation of bovine orthopedic disorders. These diagnostic imaging techniques improve the likelihood of a definitive diagnosis in every bovine patient but especially in highly valuable cattle, whose owners demand increasingly more diagnostic and surgical interventions that require high-level specialized techniques.

    D-cloprostenol is a synthetic PGF2α, commonly used in bovine reproduction, that increases myometral contractility. However, little is known regarding its contractile behaviour and how it depends on the reproductive state and uterine topography (regions and muscular layers). These aspects would affect the action of d-cloprostenol on the uterus. Therefore, we hypothesize a possible use of this drug at the time of artificial insemination, to improve conception rates and, in the post-partum, in order to accelerate uterine involution in dairy cattle. The purpose of the present study was to investigates the modulatory effect of d-cloprostenol on contractility of the bovine uterine region (horn and corpus) and their muscle layers (circular and longitudinal), in follicular and luteal phases. To our knowledge, motility effects of d-cloprostenol on different regions from healthy bovine uterus have not been described up to now. Uterine specimens were collected from uterine body and horn of cattle in the follicular (n = 28) and luteal phase (n = 32) of the estrous cycle at slaughter. Two strips were prepared from each regions corresponding to the circular and the longitudinal muscular layers, respectively. Samples were cultured in an organ bath, exposed to synthetic prostaglandin (1 μM d-cloprostenol) and their contractile activity was monitored for 10 min. The functionality of the strip throughout the experiment was tested by a dose of carbachol (10-5 M). The mean basal amplitude of contractions was higher in the follicular compared to the luteal phase in uterine horn samples, but not in muscles collected from the uterine body. The amplitude of contractions increased after d-cloprostenol administration in all tissues with a greater increase in samples from cattle in the follicular phase. The frequency of contractions increased after d-cloprostenol administration in longitudinal but not in circular fibrees. The contractile responses to d-cloprostenol in both horn and

    To describe the outcome of patients with uterine arteriovenous malformations (AVMs) after uterine artery embolization (UAE). Retrospective case series. Tertiary center of a university hospital. Thirteen patients were referred to a tertiary medical center from primary care facilities with profuse uterine bleeding. Uterine artery embolization. Thirteen patients underwent UAE. Eleven patients had no additional vaginal bleeding, whereas two patients underwent hysterectomy after embolization. Twelve patients developed AVMs after induced abortions. One patient had a congenital uterine AVM. Based on the transfer notes, eight cases had incomplete abortions, three cases had dysfunctional uterine bleeding, one case had a molar pregnancy, and one case had a uterine AVM. Two cases underwent hysterectomy after UAE. One patient delivered a healthy baby after bilateral UAE. Uterine AVMs should be suspected in patients with abrupt, profuse vaginal bleeding and a medical history of an induced abortion. Primary physicians should consider uterine AVMs with such a medical history. A prompt diagnosis and therapy are essential for favorable outcomes in patients with uterine AVMs. Crown Copyright © 2010.

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

    Full Text Available Objective: To investigate the effect of uterine artery embolization (UAE in the treatment of symptomatic uterine fibroids and the effect on ovarian function. Methods: Clinical data of 20 UAE cases admitted from August 2014 to August 2015 were retrospectively analyzed. They had uterine leiomyoma, and received UAE after menstruation 3-7 d. Seldinger technology was used to puncture the right femoral artery, microspheres was alginated or polyvinyl alcohol particles were injected into the target vessel embolism vascular leiomyoma. Broken Gelfoam embolization of uterine artery was used to stop fibroids blood supply; imaging examination of symptomatic uterine fibroids was performed before and 3 months, 6 months, 12 months after UAE. The volume of uterus myoma volume changes was observed; luteinizing hormone (LH, prolactin (PRL, follicle stimulating hormone (FSH, progesterone (PROG, estradiol (E2 changes were detected before and 3 months, 6 months, 12 months after UAE. Results: Three months, 6 months, 12 months after UAE surgery, all patients were followed up for 3 months. The volume of uterus and tumor volume were significantly reduced, and the degree of reduction was moresignificant (P0.05. Conclusions: UAE has definite efficacy, and it has little effect on ovarian function.

    In many species a transient uterine inflammatory response follows mating and is proposed to remove excess spermatozoa, bacteria, and other contaminants from the uterus. Similar events have been documented in the bitch involving increased uterine contractions, polymorphonuclear neutrophil influx and uterine artery vasodilation. Some healthy bitches with endometrial hyperplasia have increased numbers of uterine luminal polymorphonuclear neutrophils after mating and reduced fertility; it is purported that this represents a presumed postmating endometritis. This study used B-mode and Doppler ultrasonography at the time of mating to measure uterine contractions, clearance of ejaculated fluid, and uterine artery velocity in normal bitches and those with endometrial hyperplasia. Mating resulted in an increase in the number of uterine contractions, although fewer mating-induced contractions were noted in bitches with endometrial hyperplasia. Interestingly, uterine fluid cleared significantly more slowly after mating from the bitches with endometrial hyperplasia than the normal bitches (P = 0.01). In a further study, Doppler ultrasonography showed that in normal bitches there was a significant increase in uterine artery blood velocity (P = 0.04) and a decrease in the resistance index after mating (P = 0.04), indicating vasodilation. In bitches with endometrial hyperplasia the baseline resistance index was significantly higher than normal bitches (P = 0.05), and furthermore, although there was a significant decrease in resistance index after mating, in the bitches with endometrial hyperplasia this was of a smaller magnitude that in normal bitches. These findings indicate lower baseline uterine perfusion, and a blunted vasodilation response to mating in bitches with endometrial hyperplasia. Short-duration postmating administration of systemic antibiotic increased pregnancy rates in bitches with endometrial hyperplasia (P uterine vasodilatory response to mating and delaying

    We performed genomic, epigenomic, transcriptomic, and proteomic characterizations of uterine carcinosarcomas (UCSs). Cohort samples had extensive copy-number alterations and highly recurrent somatic mutations. Frequent mutations were found in TP53, PTEN, PIK3CA, PPP2R1A, FBXW7, and KRAS, similar to endometrioid and serous uterine carcinomas. Transcriptome sequencing identified a strong epithelial-to-mesenchymal transition (EMT) gene signature in a subset of cases that was attributable to epigenetic alterations at microRNA promoters. The range of EMT scores in UCS was the largest among all tumor types studied via The Cancer Genome Atlas. UCSs shared proteomic features with gynecologic carcinomas and sarcomas with intermediate EMT features. Multiple somatic mutations and copy-number alterations in genes that are therapeutic targets were identified. Copyright © 2017 Elsevier Inc. All rights reserved.

    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.

    In order to determine the morphology and the normal values of uterine contractility during the puerperium, 26 patients with the following characteristics were studied: multiparous during puerperium, without recent episiotomy, with healthy cervix, absence of genital septic focus, uterine tumours or malformations; all of them breast feeding. In the hypothesis it was considered that the endogenous oxytocin increases and stimulates the mammary myoepithelium and uterine contractility. For recording uterine contractility, the technique of Jaumandreu and Hendricks was used. The recordings were made during the 24 hours postpartum, at 5, 10, 20, 30 and 40 days with a duration of 2 to 3 hours. All the studies were longitudinal. The change of human uterine contractility during normal puerperium were estimated. The range of the tonus was 22--41 mmHg, the intensity 5--18 mmHg, the frequency 17--23 contractions in 10 minutes, and the uterine activity 102--223 Montevideo Units.

    To report a placenta percreta in a 7-week gestational rudimentary noncommunicating uterine horn pregnancy. A 28-year-old woman with no complaints presented with a rudimentary uterine horn pregnancy at 7-weeks gestation. The diagnosis was suspected by ultrasonography and diagnosed by laparoscopy. Laparoscopic excision of the rudimentary uterine horn and ipsilateral salpingectomy were performed, as well as biopsy of several peritoneal endometriosis lesions. A 7-week gestation pregnancy with placenta percreta was identified in the rudimentary uterine horn. No communication was found with the right unicornuate uterus. Endometriosis was confirmed. Clinical outcome was favorable. Placenta percreta may occur in rudimentary uterine horn pregnancies, but accidents may be avoided by an early diagnosis and surgical management. However, in young women who desire pregnancy, planned laparoscopic resection of a rudimentary uterine horn revealed accidentally should be discussed.

    Correct uterine contraction activity during labour determines physiological fetal delivery and ensures its satisfactory outcome. Contraction activity monitoring may be accomplished by either recording of the mechanical properties of the uterine muscle and/or by measurement of the action potentials produced by the uterus during contraction. In the following paper, the current state of knowledge concerning the methods for assessment and monitoring of the uterine contraction activity was evaluated. The electrophysiological properties of the uterus were given. The mechanical methods of uterine activity monitoring: internal and external tocography were described. The development of the electrohysterography as the method providing the signal comprising complete information on bioelectrical properties of the uterine muscle was presented. The conclusion was that the analysis of the electrohysterogram enables a description of the source of the uterine contraction activity, whereas currently applied mechanical methods merely record the results of this activity.

    Sclerocarya birrea (Anacardiaceae), popularly known as "marula", is used as a traditional remedy for allegedly treating dysmenorrhoea and a host of other ailments such as malaria, fever, diarrhoea, dysentery, stomach disorders, headaches and to facilitate childbirth. This study investigated the pharmacological effects of S. birrea extract (SBE) on isolated, spontaneously-contracting uterine horns of healthy, young adult, female Wistar rats. One kilogramme of S. birrea fresh stem bark was identified and authenticated. The bark was air-dried at room temperature (26 ± 1°C) for two weeks. The dried stem bark was milled and macerated in 2.5l of distilled water for 48 h and filtered. A rotary evaporator was used to concentrate the aqueous extract by drying it at 60 ± 1°C. Freeze-drying gave 61.3g/kg (i.e., 6.13% yield) of a dark-brown, powdery, crude extract. Rat isolated uterine horns were mounted in 25-ml Iworx tissue organ-baths containing De Jalon׳s physiological solution, and exposed to graded concentrations of SBE (25, 50, 100, 200, 300, 400mg/ml/kg). The effects of SBE and atropine, oxytocin, verapamil, indomethacin, acetylcholine, serotonin, cimetidine and histamine on the isolated uterine muscles, were recorded using LabScribe2 software. The aqueous stem bark extract of S. birrea produced significant (pcontractions of the uterine horn muscle preparation reaching a maximum at the 300 mg/ml dose. SBE mimicked and potentiated uterine muscle contractile effects of oxytocin (0.5-5 µU/ml) and acetylcholine (0.1-3 µg/ml). Pre-incubation of tissues with atropine (1-3 µg/ml), non-significantly (p>0.05) inhibited SBE-induced contractions on uterine muscles. Verapamil (2 µg/ml), indomethacin and -p-tosyl-l-phenylalanine-chloromethyl-ketone (TPCK) inhibited the contractile effects of SBE (25-400mg/ml/kg), suggesting possible calcium-mediated mechanism of action for SBE and possible COX-enzyme inhibition.

    Uterine arteriovenous malformation (AVM) is characterized by shunts between the myometrial arteries and veins. Treatment is based on the severity of uterine bleeding and ranges from conservative medical approaches to embolization of affected arteries. The aim of study was to evaluate the feasibility and safety of hysteroscopy for management of uterine AVM. This was a retrospective study of a cohort of 11 cases occurring between March 2012 and December 2015 in our Regional Center of Excellence in Hysteroscopy, University of Florence. The diagnosis of AVM was made by transvaginal ultrasonography with high-definition flow in patients with mild to moderate symptoms. In all cases, we used the hysteroscopic platform Gynecare VersaPoint II (Ethicon, Somerville, New Jersey, USA), equipped with a 4-mm electrosurgical loop and associated with the SPIES (Storz Professional Image Enhancement System) system (Karl Storz, Tuttlingen, Germany). All patients were successfully treated with operative hysteroscopy with no reported complications. No patient had residual disease detected by ultrasonography performed after a month. At this writing, of the 11 patients treated with operative hysteroscopy, 4 had achieved a pregnancy that carried to term, 1 was pregnant at 20 wk, and 1 had a miscarriage in the first trimester. Hysteroscopy is a feasible and safe alternative treatment modality for AVM. Patients treated with surgical hysteroscopy have high fertility outcomes, a 100% success rate after the first treatment, no complications related to the surgical procedure, and a short hospital stay.

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

    Full Text Available Uterine rupture and fetal maceration in an 11 year old mongrel bitch was diagnosed via lateral abdominal radiography and ventral midline laparotomy. The treatment of choice in cases of uterine rupture and fetal maceration is bilateral ovariohysterectomy along with plenty of intravenous fluid therapy and broad spectrum antibiotics. Incidences of uterine rupture and fetal maceration can be prevented by timely recognition of early signs of obstetrical-related complications and use of proper obstetrical techniques.

    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.

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

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

    Dubey, J P; Buxton, D; Wouda, W

    2006-05-01

    The protozoan parasite Neospora caninum is a major pathogen of cattle and dogs, being a significant cause of abortion in cattle in many countries. It is one of the most efficiently transmitted parasites, with up to 90% of cattle infected in some herds. The pathogenesis of abortion due to Neospora is complex and only partially understood. Losses occur after a primary infection during pregnancy but more commonly as the result of recrudescence of a persistent infection during pregnancy. Parasitaemia is followed by invasion of the placenta and fetus. It is suggested that abortion occurs when primary parasite-induced placental damage jeopardises fetal survival directly or causes release of maternal prostaglandins that in turn cause luteolysis and abortion. Fetal damage may also occur due to primary tissue damage caused by the multiplication of N. caninum in the fetus or due to insufficient oxygen/nutrition, secondary to placental damage. In addition, maternal immune expulsion of the fetus may occur associated with maternal placental inflammation and the release of maternal pro-inflammatory cytokines in the placenta. Thus N. caninum is a primary pathogen capable of causing abortion either through maternal placental inflammation, maternal and fetal placental necrosis, fetal damage, or a combination of all three. The question of how N. caninum kills the fetus exposes the complex and finely balanced biological processes that have evolved to permit bovine and other mammalian pregnancies to occur. Defining these immunological mechanisms will shed light on potential methods of control of bovine neosporosis and enrich our understanding of the continuity of mammalian and protozoal survival.

    2015-02-01

    Understanding the variability caused by uterine position effects in polytocus species, such as rats, may enhance prenatal animal models for the study of drug and environmental agents. The primiparous litters of 42 intact female Sprague-Dawley rats were studied. Uterine position, fetal body weight, and fetal brain (wet) weight were recorded on gestation day (GD) 20 (GD 0=sperm positive). Uterine position effect for brain and body weight varied depending upon horn size. Furthermore, an inverse relationship between horn size (and, to a lesser extent, litter size) and fetal weight applied to both body and brain weight measures. There were no statistical differences in brain and body weights between the left and right uterine horns. The position of the uterine horn (left vs. right) and litter size did not influence the uterine position effect in the rat. Collectively, the present data suggest the presence of a significant uterine position effect. Prenatal differences based on uterine position provide an untapped opportunity to increase our understanding of developmental neurotoxicological and teratological studies that employ a polytocus species as an animal model.

The prevalences were examined in three age groups: 35-39 yrs, 40-44 yrs and ≥ 45 yrs. The significance of both diagnoses on fertility was assessed using logistic regression analysis. Results :Uterine fibroids were detected in 25.8% (47/182 of patients with endometriosis. Endometriosis was detected in 19.6% (47/240 of patients with uterine fibroids. 5.5% (10/183 women undergoing sterilization had endometriosis and 19.3% (17/183 had uterine fibroids. Both uterine fibroids and endometriosis were, independently of each other, related to subfertility (OR, 95% CI: 3.8, 2.3-6.5; 6.8, 4.0-11.6, respectively. Conclusions : The results suggest that symptomatic endometriosis appears together with symptomatic uterine fibroids. Both diseases seem to decrease female fertility independently of each other.

Nowadays, the management of UF pathology is undergoing an important evolution, with the patient’s quality of life being the most important aspect to consider. Accordingly, surgical techniques and aggressive treatments are reserved for only those cases with heavy symptomatology, while the clinical diagnostic based on size and number of UFs remains in a second plane in these situations. Moreover, the development of several noninvasive surgical techniques, especially the appearance of ulipristal acetate as a medical etiological treatment, has substantially changed the clinical indications. As a consequence, after almost 2 decades without relevant updates, it has been necessary to update the protocols for the management of UFs in the Spanish Society of Gynecology and Obstetrics twice. Accordingly, we believe that it is necessary to translate our experience to protocolize the medical care for patients with UFs, incorporating these new therapeutic options, and selecting the best treatment for them. We highlight the importance of achieving the patient’s goals and decisions by improving the clinical diagnosis for these type of pathologies, allowing enhanced personalized treatments, as well as the reduction of potential risks

    The immunogenicity of an intranasally-administered modified-live virus (MLV) vaccine in 3-8 day old calves was evaluated against bovine viral diarrhea virus (BVDV) types 1 and 2, infectious bovine rhinotracheitis (IBR) virus, parainfluenza-3 (PI-3) virus and bovine respiratory syncytial virus (BRSV). Calves were intranasally vaccinated with a single dose of a multivalent MLV vaccine and were challenged with one of the respective viruses three to four weeks post-vaccination in five separate studies. There was significant sparing of diseases in calves intranasally vaccinated with the MLV vaccine, as indicated by significantly fewer clinical signs, lower rectal temperatures, reduced viral shedding, greater white blood cell and platelet counts, and less severe pulmonary lesions than control animals. This was the first MLV combination vaccine to demonstrate efficacy against BVDV types 1 and 2, IBR, PI-3 and BRSV in calves 3-8 days of age. Copyright 2010 Elsevier Ltd. All rights reserved.

    Postpartum haemorrhage (PPH) is a major cause of worldwide maternal mortality and is still associated with significant morbidity. After the B-Lynch suture was reported in 1997, several different uterine compression sutures were found to be successful in controlling PPH. In this paper, we describe another simple variation of the uterine compression suture technique, which was performed without an incision in the uterine wall, without entering the uterine cavity and without suturing the anterior and posterior walls of the uterus together, so minimising the trauma to the uterus. This new uterine compression suture is an effective and safe surgical treatment for PPH caused by atony. It has the potential to apply to intractable PPH after vaginal delivery.

    Full Text Available Abstract Introduction Uterine rupture is an obstetric complication associated with significant maternal and fetal morbidity and mortality. This disorder usually occurs with a scarred uterus, especially in a uterus with prior Cesarean section. Uterine sacculation or diverticulum may also lead to a thin uterine wall during pregnancy. Case presentation A 27-year-old Japanese primigravid woman was admitted to our hospital due to weak, irregular uterine contractions in her 38th week of gestation. She had no past history of uterine surgery or known diseases. A hard mass was palpable in her abdomen. An ultrasound revealed that the anterior uterine wall was thin and bulging, with a fetal minor part beneath it which corresponded to the palpated mass. A Cesarean section was performed which revealed a thin anterior uterine wall with incomplete uterine rupture. The woman and baby were healthy. Conclusions Although extremely rare, an unscarred primigravid uterus can undergo incomplete rupture even without discernable risk factors or labor pains. Abdominal palpation and ultrasound may be useful in detecting this condition.

    Full Text Available Bovine Herpesvirus 4 (BoHV-4 is a member of Gammaherpesvirinaesub-family and belongs to genus Rhadinovirus. This virus has been associated with different clinical manifestations and research activity has put forward a strong correlation among virus infection, postpartum metritis, and abortion. The goal of this work was to characterize a virus strain isolate from a cow’s uterine outflow. From swabs drawn of uterine secretion, a virus strain was isolated and characterized by its cytopathology, morphology, and molecular biology approaches. In culture there was CPE development, characterized mainly by long strands with several small balloons along them, radiated from infected cells. Electron microscopy analysis revealed virus particles that had icosahedrical capsid symmetry surrounded by a loose envelope, typical of a herpesvirus. A 2,571 bp PCR product after HindIII digestion generated four fragments, whose base pair composition were 403, 420, 535, and 1,125 bp. Restriction enzymes HindIII and BamHI generated the expected diagnostic bands as well as a 2,350 bp hypermolar fragment as a result of BamHI treatment to demonstrate that agent was a bovine herpesvirus 4, appertaining to DN-599 group.

    In more than 10 Spanish dairy cows, a bovine herpesvirus 4 (BHV4) associated postpartum metritis was confirmed by virus isolation, BHV4-glycoprotein B (gB) PCR and/or serology. In this study, 12 cows with, and, at the time of sampling, 3 cows without clinical signs of acute postpartum metritis from one large dairy herd in Spain were examined for bacterial and viral infections. Blood, placenta/caruncles and uterine contents were collected between day 1 and day 20 post-calving, and examined for the presence of bacteria and for viruses by virus isolation, BHV4 DNA by BHV4-gB PCR and/or BHV4 antibody titres. Bovine herpesvirus 4 was detected in 83% of the cases with clinical signs of acute postpartum metritis by virus isolation and/or BHV4-gB PCR. An increase of BHV4 antibodies was detected in all examined postpartum metritis cows and in the 3 cows without clinical metritis. Two of these 3 cows developed severe metritis a few dayss after collecting the first blood sample. A concurrent infections of BHV4 and bacteria, mainly Arcanobacterium pyogenes and Streptococcus sp., were detected in 73% of the examined uterine contents collected from postpartum metritis affected cows. This case-report study showed a clear association between BHV4 infections and acute postpartum metritis in dairy cows. In addition, the BHV4-associated postpartum metritis appeared to be an emerging syndrome in this Spanish herd.

    This in vitro study investigates the modulatory effect of three antibiotics (amoxicillin, enrofloxacin, and rifaximin) on contractility of the bovine uterine tissue in follicular and luteal phases. The effects of these antibiotics at three single doses (10(-6), 10(-5), and 10(-4) M) on their basal contractility were evaluated in isolated organ bath. The functionality of the strip throughout the experiment was evaluated by a dose of carbachol (10(-5) M); the obtained effect had to be repeatable (difference of ≤20%) that is comparable to that induced by the previous administration of the same substance. The results demonstrate the different modulatory activities of these antibiotics on uterine contractility in follicular and luteal phases. The effects induced by amoxicillin and enrofloxacin are opposite: the first relaxes and the second increases the uterine contractility in both cycle phases. Instead, the activity of rifaximin varies depending on the phase of estrous cycle: it increases in the follicular phase and relaxes in the luteal phase. The obtained data provide the hypothesis of possible implications of these drugs in the pharmacologic modulation of uterine contractions. Their action at this level, associated with their specific antimicrobial effects, could suggest using these antibiotics for the treatment of diseases related to postpartum or infections that may occur in pregnant cattle, by virtue of their effects on myometrial contractility too.

    Full Text Available Purpose. To examine the uterine involution period after uncomplicated delivery in primiparous and multiparous women. Methods. Longitudinal prospective study. Repeated parameters were measured and endometrial contents and diastolic notch were observed. Measurements of primiparous and multiparous women were carried out after labour on the 1st, 3rd, 10th, 30th, 42nd, and 60th postpartum days. The analysis was performed using SPSS version 21. Results. The median uterus parameters are bigger in multiparous group in physiological puerperium, but the decreasing trend is the same. The endometrial cavity on the 10th day was significantly wider in multiparous women and mainly echo-negative view of the uterine cavity was observed. The evaluation of the uterine angle deviation changes from an extremely retroverted position to a more anteverted position. RI of the uterine artery in both groups was low immediately after labour and significantly increased one month postpartum. Notching of the uterine artery undergoes changes, but diastolic notch does not appear in all postpartum women even after two months following labour. Conclusions. The puerperium period after normal vaginal delivery depends on parity. The trend of involution in primiparous and multiparous women follows a similar pattern, yet, it lasts longer in the multiparous women. Ultrasound of uterine is certainly a useful tool after labour and may be important in facilitating an early detection of postpartum uterine complications.

    2011-04-01

    Full Text Available Uterine torsion is a twisting of the uterus or uterine horn perpendicular to its long axis.We report a case of uterine torsion in an adult breeding Sprague Dawley rat. The rat died a month after her last recorded delivery. Post mortem examination of the rat revealed 270° torsion of the right uterine horn. The uterus contained a single foetus. The liver was pale and enlarged. The rest of the viscera appeared normal. Histopathological examination showed acute hepatic necrosis and pulmonary congestion with mild lymphocytic infiltrates peribronchially. The acute hepatic necrosis may have been associated with septicaemia due to compromised blood vessels following the uterine torsion. The presence of a single foetus could have resulted in foeto-maternal disproportion with resultant uterine torsion. Torsion of the uterus can be accompanied by haemostatic and metabolic complications, which could have caused the death of the rat. Although uterine torsion is a rare condition in rats, it should be considered as a potential complication of gestation in animal breeding units.

    The relationship between abortion and uterine fibroids has received little attention. The aim of the present study was to explore the association between number of induced and spontaneous abortions and the risk of uterine fibroids in middle-aged and older Chinese women. A total of 14,595 retired female employees from the Dongfeng-Tongji cohort study were included in our analysis. Information on induced and spontaneous abortions was collected by trained interviewers through face-to-face interviews. Diagnosis of uterine fibroids was based on ultrasound or self-reported physician diagnosis of uterine fibroids. Logistic regression models were used to explore the associations between number of induced and spontaneous abortions and the risk of uterine fibroids. The prevalence of uterine fibroids was 15.1% among all participants. Higher number of induced abortions was associated with an increased risk of uterine fibroids (1 induced abortion: odds ratios [ORs] = 1.32, 95% confidence interval [CI] 1.18-1.48; 2 induced abortions: OR = 1.45, 95% CI 1.28-1.64; and ≥3 induced abortions: OR = 1.62, 95% CI 1.39-1.90). Compared with women without induced abortion, ORs for women with 1, 2, and ≥3 were 1.17 (95% CI 1.03-1.32), 1.21 (95% CI 1.06-1.39), and 1.36 (95% CI 1.15-1.61), respectively, after adjustment for potential confounders. No association was observed between the number of spontaneous abortions and the risk of uterine fibroids. The findings of this study showed that induced abortion may be an independent risk factor for uterine fibroids in middle-aged and older Chinese women.

    Uterine leiomyosarcomas are rare tumours, and secondary cardiac metastases are even rarer. We present the case of a 56-year-old ethnic Chinese woman who was being treated with adjuvant pelvic radiation for uterine leiomyosarcoma when she presented with signs of right heart failure and shock. She was rapidly diagnosed with a solid mass attached to the tricuspid valve. Subsequent surgical resection revealed leiomyosarcoma metastasis. Metastases of uterine leiomyosarcoma to the heart are extremely rare, but clinicians should be aware of this phenomenon. Surgical resection, when feasible, can be associated with longer survival.

    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.

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

    To investigate the incidence, etiology, diagnosis, treatment and outcome of uterus rupture. From January 1999 to May 2013, clinical data of 67 cases with uterine rupture in Woman's Hospital, School of Medicine, Zhejiang University were studied retrospectively. A total of 67 cases of uterine rupture with 21(+2)-39(+2) gestational weeks out of 128 599 deliveries were recorded giving an incidence of uterine rupture was 0.052 1% (67/128 599) . Cesarean scar rupture were found in 59 cases (88%, 59/67) and noncesarean scar rupture were found in 8 cases (12%, 8/67). The causes of uterine rupture include 60 cases of scar uterus (59 cesarean scar cases and 1 myomyectomy scar case), 2 cases of assisted delivery operation trauma, 2 cases of malformed uterus, 3 cases of unknown causes (all with artificial abortion history).Non obstructive dystocia and improper oxytocin use were found to be related with uterine rupture.Fifty-two cases of cesarean scar spontaneous incomplete rupture were found and repaired during repeated cesarean delivery without maternal and fetal complications. The remaining 15 cases need emergency rescue operation for fetal distress or dead fetus, severe acute abdomen, prepartum or postpartum vaginal bleeding even maternal hypovolemia; 6/15 uterine rupture cases were diagnosed with the history, clinical symptoms and signs, 3/15 cases with ultrasonic found dead fetus in the peritoneal cavity before exploratory laparotomy and 6 cases were diagnosed just during laparotomy.Hysterectomy was done in 10/15 cases and uterine repair in 5/15 cases; there was no maternal death and 12 perinatal fetal death (5 cases of mid-late pregnancy termination for deformed fetus) of the 15 uterine rupture cases.One case with hysterectomy was complicated with stress pancreatitis and dysfunction of liver and kidney and discharged 20 days after operation, the remaining 14 cases were discharged 5-7 days postpartum.One case with repaired malformed uterus got pregnancy 4 years later and

    Uterine arteriovenous malformations (AVM) are rare and can be classified as either congenital or acquired. Acquired AVMs may result from trauma, uterine instrumentation, infection or gestational trophoblastic disease. The majority of acquired AVMs are encountered in women of reproductive age with a history of at least one pregnancy. Traditional therapies of AVMs include medical management of symptomatic bleeding, blood transfusions, uterine artery embolization (UAE) or hysterectomy. In this retrospective case series, we report our experience with AVM and UAE in five symptomatic women of reproductive age who wished to preserve fertility. Patients were 18-32 years old, and had 1-3 previous pregnancies prior to initial presentation. All patients were followed until their deliveries. All five patients delivered live births. Three of the five patients required two embolization procedures and one of these women required a subsequent hysterectomy. Two deliveries were at term and had normal weight babies and normal placenta. One woman had cerclage placed and developed chorioamnionitis at 34 weeks but had a normal placenta. Two pregnancies were induced AVM as previously thought and should be questioned as an initial therapy in symptomatic women of reproductive age desiring fertility preservation. © The Author 2015.

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

    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.

    To analyze the prognostic factors for survivals and to evaluate the impact of postoperative whole pelvic radiotherapy (WPRT) on pelvic failure in patients with uterine sarcoma treated with radical surgery. We retrospectively analyzed 75 patients with uterine sarcoma who underwent radical surgery with (n = 22) or without (n = 53) radiotherapy between 1990 and 2010. There were 23 and 52 patients with carcinosarcoma and non-carcinosarcoma (leiomyosarcoma, 22; endometrial stromal sarcoma, 25; others, 5), respectively. The median follow-up period was 64 months (range, 17 to 269 months). The 5-year overall survival (OS) and pelvic failure-free survival (PFFS) of total patients was 64.2% and 83.4%, respectively. Multivariate analysis revealed that mitotic count (p = 0.006) was a significant predictor of OS. However, factors were not found to be associated with PFFS. On analyzing each of the histologic subtypes separately, postoperative WPRT significantly reduced pelvic failure in patients with carcinosarcoma (10.0% vs. 53.7%; p = 0.046), but not in patients with non-carcinosarcoma (12.5% vs. 9.9%; p = 0.866). Among the patients with carcinosarcoma, 4 patients (17%) had recurrence within the pelvis and 3 patients (13%) had recurrence in other sites as an initial failure, whereas among the patients with non-carcinosarcoma, 3 patients (6%) experienced pelvic failure and 13 patients (25%) experienced distant failure. The most significant predictor of OS was mitotic count. Based on the improved PFFS after postoperative WPRT only in patients with carcinosarcoma and the difference in patterns of failure between histologic subtypes, optimal adjuvant treatment options should be offered to patients based on the risk of recurrence patterns.

    Uterine arteriovenous malformation (AVM) is a potentially life-threatening condition characterized by abrupt and profuse uterine bleeding from abnormal connections between arteries and veins in the myometrium. It is commonly associated with prior pregnancy or uterine trauma. We present a case of severe uterine AVM treated with danazol and transarterial embolization (TAE). A 38-year-old patient with a history of two abortions and a myomectomy was referred to our hospital for intermittent massi...

    Uterine arteriovenous malformations (AVMs) are extremely rare and can result in severe complications. Experience with diagnosis and management of these vascular malformations is very limited. We report on a patient with a history of nonmetastatic gestational trophoblastic disease. The patient developed a concomitant 4.4-cm intrauterine mass, suggestive of a molar pregnancy, during her second pregnancy. Despite suction and sharp curettage, the mass and menorrhagia persisted. After complex diagnostic imaging, the diagnosis of a uterine AVM was made. Subsequently, the patient underwent uterine arterial embolization and laparoscopic surgery to resect the mass. Because uterine AVMs are infrequently encountered, they initially may not be included in the differential diagnosis. The use of contemporary imaging, interventional radiology, and surgery can optimize patient outcome.

    To describe childbearing prognosis following embolization therapy for uterine arteriovenous malformation (AVM). Case report and review. University hospital. Thirteen patients, including our case, who underwent pregnancy after embolization therapy for arteriovenous malformation. Two successive embolization procedures. Childbearing prognosis following embolization therapy for uterine AVM. Bilateral embolization was performed in seven patients. In four cases, including ours, two successive embolization procedures were required to treat the uterine AVM. The longest delay between embolization and pregnancy was 5 years and the shortest was six weeks. Two patients presented with postpartum hemorrhage which was treated medically. One neonate required resuscitation after delivery in the context of Listeria infection. Conservative management of uterine AVMs using embolization therapy is being increasingly developed. New embolization agents and hyperselective technical procedures aim at reducing morbidity related to such treatments and preserving reproductive capacity in women of childbearing age.

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

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

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

    The investigators present a novel image-guided embolization, not previously described, of a uterine arteriovenous malformation (AVM) resistant to endovascular management. The uterus was exposed surgically, and Histoacryl (Braun, Fulda, Germany) was injected directly into the nidus using ultrasound guidance and fluoroscopy. The patient had a successful full-term pregnancy after this procedure. This technique may be a useful alternative management strategy in patients with uterine AVM who fail traditional endovascular embolization and who still desire fertility.

    The present study was undertaken to explore the relationship between environmental exposure and risk of uterine leiomyoma in women using an epidemiologic survey. We conducted a case-control survey of premenopausal Han women aged 30-50 years in Nanjing. The subjects included 600 patients with uterine leiomyoma confirmed at the Affiliated Zhongda Hospital of Southeast University between February 2010 and June 2012 and 600 patients with non-uterine leiomyoma or healthy volunteers who presented to the above mentioned hospital for physical examination during the same period. We entered the results into a database and explored the relationship between risk factors and prevalence of uterine leiomyoma using univariate or multivariate non-conditional logistic regression analysis. The results showed that patients aged 40-45 years had a high prevalence of uterine leiomyoma. The prevalence of uterine leiomyoma in subjects with an education beyond high school was higher than in those with a high school education or less. Exposure to plastic products (odds ratio [OR]: 1.481; 95% confidence interval [CI]: 1.046-2.097); exposure to cosmetics and other chemicals (OR: 1.954; 95% CI: 1.479-2.582); and consumption of soybean milk (OR: 2.518; 95% CI: 1.894-3.347), food additives, sweeteners, and preserved food (OR: 3.166, 95% CI: 2.247-4.461) had a significant effect on the occurrence of uterine leiomyoma (p cosmetics, and other chemicals as well as intake of soybean milk, food additives, sweetener, and preserved foods may be risk factors for uterine leiomyoma.

    Uterine fibroids (also known as leiomyomas or myomas) are the most common form of benign uterine tumors. Clinical presentations include abnormal bleeding, pelvic masses, pelvic pain, infertility, bulk symptoms and obstetric complications.Almost a third of women with leiomyomas will request treatment due to symptoms. Current management strategies mainly involve surgical interventions, but the choice of treatment is guided by patient's age and desire to preserve fertility or avoid 'radical' surgery such as hysterectomy. The management of uterine fibroids also depends on the number, size and location of the fibroids. Other surgical and non-surgical approaches include myomectomy by hysteroscopy, myomectomy by laparotomy or laparoscopy, uterine artery embolization and interventions performed under radiologic or ultrasound guidance to induce thermal ablation of the uterine fibroids.There are only a few randomized trials comparing various therapies for fibroids. Further investigations are required as there is a lack of concrete evidence of effectiveness and areas of uncertainty surrounding correct management according to symptoms. The economic impact of uterine fibroid management is significant and it is imperative that new treatments be developed to provide alternatives to surgical intervention.There is growing evidence of the crucial role of progesterone pathways in the pathophysiology of uterine fibroids due to the use of selective progesterone receptor modulators (SPRMs) such as ulipristal acetate (UPA). The efficacy of long-term intermittent use of UPA was recently demonstrated by randomized controlled studies.The need for alternatives to surgical intervention is very real, especially for women seeking to preserve their fertility. These options now exist, with SPRMs which are proven to treat fibroid symptoms effectively. Gynecologists now have new tools in their armamentarium, opening up novel strategies for the management of uterine fibroids. © The Author 2016

    Garnock-Jones, Karly P; Duggan, Sean T

    2017-10-01

    Oral ulipristal acetate (Esmya®; Fibristal®), a synthetic selective progesterone receptor modulator, is the first selective progesterone modulator to be approved for the treatment of uterine fibroids. It was initially approved for the preoperative treatment of moderate to severe uterine fibroid symptoms in women of reproductive age. Recently, the indication was extended in the EU to include the intermittent treatment of moderate to severe uterine fibroid symptoms. This narrative review summarizes pharmacological, efficacy and tolerability data relevant to the preoperative and intermittent use of ulipristal acetate in patients with symptomatic uterine fibroids. Ulipristal acetate is an effective and generally well tolerated treatment for patients with symptomatic uterine fibroids, both as preoperative, single-course treatment and as intermittent, longer-term treatment. It is noninferior in efficacy to intramuscular leuprolide acetate, as a preoperative treatment, and is associated with a lower rate of hot flashes, a common adverse event with gonadotropin-releasing hormone analogues. Thus, ulipristal acetate is an effective option for both preoperative and intermittent treatment of moderate to severe, symptomatic uterine fibroids in women of reproductive age.

    Uterine arteriovenous malformation (AVM) is a rare but potentially life-threatening condition. AVMs often present with intractable bleeding and commonly are seen in association with pregnancy and uterine trauma. Ultrasound is the most common form of initial investigation, and computed tomography and magnetic resonance imaging are being used with greater frequency. Despite this, angiography remains the gold standard for diagnostic evaluation. Embolization has become a more acceptable form of treatment and allows more invasive forms of treatment, particularly hysterectomy, to be avoided. Numerous medical therapies have also been used in the management of patients with uterine AVM. Reports of successful pregnancies after diagnosis and treatment of a uterine AVM are still uncommon, but increasingly good outcomes are being reported after successful treatment of a confirmed uterine AVM. Obstetricians & Gynecologists, Family Physicians Learning Objectives: After completion of this article, the reader should be able to describe the many and varied clinical manifestations of a uterine arteriovenous malformation (AVM), summarize the best ways to manage an acute hemorrhage from an AVM, and identify the current best way to diagnose an AVM.

    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.

    Postpartum hemorrhage is the leading cause of maternal mortality worldwide. Vacuum-induced uterine tamponade is a possible alternative approach to balloon tamponade systems for the treatment of postpartum hemorrhage resulting from atony. In a prospective proof-of-concept investigation of 10 women with vaginal deliveries in a hospital setting who failed first-line therapies for postpartum hemorrhage, tamponade was used. Vacuum-induced uterine tamponade was created through a device inserted transvaginally into the uterine cavity. An occlusion balloon built into the device shaft was inflated at the level of the external cervical os to create a uterine seal. Negative pressure was created by attaching a self-contained, mobile, electrically powered, pressure-regulated vacuum pump with a sterile graduated canister. In all 10 cases, the suction created an immediate seal at the cervical os, 50-250 mL of residual blood was evacuated from the uterine cavity, the uterus collapsed and regained tone within minutes, and hemorrhaging was controlled. The device remained in place for a minimum of 1 hour and up to 6.5 hours in one case while vaginal and perineal lacerations were easily repaired. This preliminary investigation suggests that a device designed to create vacuum-induced uterine tamponade may be a reasonable alternative to other devices used to treat atonic postpartum hemorrhage.

All patients with uterine and ovarian carcinosarcoma who underwent surgical staging at the 2 participating institutions between 1995 and 2007 were identified. The Kaplan-Meier method was used to generate overall survival (OS) data. Factors predictive of outcome were compared using the Cox proportional hazards model. Analysis of 87 women with uterine carcinosarcoma and 71 with ovarian carcinosarcoma was performed. Of those, 47% of the patients with uterine carcinosarcoma, compared to 14% of the patients with ovarian carcinosarcoma, were diagnosed with localized disease (p 65 years old (p extension (local versus regional versus distant, p Cox regression model, age > 65 years old (hazard ratio [HR] = 2.5, p extension (locoregional versus distant, HR = 3.9, p = 0.006), and uterine versus ovarian carcinosarcoma (HR = 2.2, p = 0.009) were identified as independent predictors of OS. Uterine carcinosarcoma presents at an earlier stage than does ovarian carcinosarcoma. In the multivariate analysis uterine carcinosarcoma demonstrated shorter survival than did ovarian carcinosarcoma after adjustment for extent of disease spread, age, and platinum-based chemotherapy.

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

    Full Text Available OBJECTIVES: To investigate the effect of phenolic environmental estrogens on uterine leiomyoma from the perspective of clinical epidemiology. METHODS: Urine and blood samples were collected from Han women with uterine leiomyoma and women without uterine leiomyoma, living in Nanjing, China, between September 2011 and February 2013. A total of 156 urine samples and 214 blood samples were collected from the uterine leiomyoma group and 106 urine samples and 126 blood plasma samples from the control group. Bisphenol A (BPA, nonylphenol (NP and octylphenol (OP concentrations were determined by solid-phase extraction (SPE coupled with liquid chromatography-tandem mass spectrometry (HPLC-MS/MS. RESULTS: Phenolic environmental estrogens in the uterine leiomyoma and control groups were compared based on: gravida>3 and gravida ≤ 3. In participants with gravida>3, urine OP concentration was significantly (P0.05 different between gravida>3 and gravida ≤ 3 patients. There was no significant (P>0.05 difference in plasma concentrations of BPA, OP and NP between the leiomyoma group and control group. Mean exposure concentration and range of distribution of BPA, OP and NP plasma concentration differed between the uterine leiomyoma and control group. CONCLUSION: Exposure level of phenolic environmental estrogens in human was related with leiomyoma tumorigenesis.

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

    The maternal portion of the bovine placenta receives blood mainly from the uterine arteries (AUT) and the fetal portion from the umbilical arteries (AUM). Placental perfusion is crucial for fetal development and undergoes adaptive changes during pregnancy according to the fetal requirements. One goal of this study was to investigate changes in Doppler sonographic measurements of blood vessels that supply blood to the placenta in cows during the last 4 weeks of pregnancy. Another goal was to examine how these measurements are affected by three drugs commonly used in cows at the time of parturition. Nine cows underwent Doppler sonographic examination of the AUT ipsilateral and contralateral to the pregnant horn and one AUM three times per week during the last 4 weeks of gestation. This was followed by the randomized administration of one of the three following experimental drugs per day: isoxsuprine (200 mg/cow, iv), xylazine (2 mg/100 kg, iv), and lidocaine for epidural anesthesia (100 mg/cow). Doppler sonographic examination was repeated 30 minutes after medication. Maternal pulse rate increased during the study period (P Doppler sonographic measurements of uterine and AUM change little in the last month of pregnancy in the cow. Isoxsuprine and epidural anesthesia with lidocaine have the potential to improve uterine perfusion. Copyright © 2014 Elsevier Inc. All rights reserved.

    The all-alpha helix multi-domain protein bovine serum albumin (BSA) aggregates at elevated temperatures. Here we show that these thermal aggregates have amyloid properties. They bind the fibril-specific dyes Thioflavin T and Congo Red, show elongated although somewhat worm-like morphology...... and characteristic amyloid X-ray fiber diffraction peaks. Fibrillation occurs over minutes to hours without a lag phase, is independent of seeding and shows only moderate concentration dependence, suggesting intramolecular aggregation nuclei. Nevertheless, multi-exponential increases in dye-binding signal...... and changes in morphology suggest the existence of different aggregate species. Although beta-sheet content increases from 0 to ca. 40% upon aggregation, the aggregates retain significant amounts of alpha-helix structure, and lack a protease-resistant core. Thus BSA is able to form well-ordered beta...

    To determine whether bovine tear film contains the iron-binding glycoprotein, lactoferrin. 40 Adult Hereford, Angus, and Simmental cattle. Protein analysis: pooled bovine tears were used for protein analysis (size exclusion high-performance liquid chromatography [HPLC] fractionation). HPLC was used for tear analysis. A diode array detector was used (215 and 280 microns) for chromatogram analysis and comparisons. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE): protein electrophoresis was performed, using 7.5% running gels with 4% stacking gels. Molecular weight of proteins in the unknown samples was determined as recommended by the manufacturer of the standards. Protein sequencing: amino acid sequencing, using automated Edman degradation of HPLC purified protein, was performed. The sequence obtained was compared with the known protein sequence of bovine lactoferrin. HPLC analysis of whole bovine tears resulted in a consistent chromatogram. Peak collection was performed to recover a protein from the bovine tear film with chromatogram characteristics nearly identical to purified bovine lactoferrin. Silver-stained SDS-PAGE of this peak revealed a band with molecular mass consistent with bovine lactoferrin (estimated mass of 78 kd). The first 13 amino acid residues of this protein were identical to the amino acid sequence of bovine lactoferrin. Analysis of whole bovine tears, using size exclusion HPLC, SDS-PAGE, and amino acid sequencing, provided evidence that bovine tears contain lactoferrin. Lactoferrin probably exerts a bacteriostatic effect in bovine tear film. Locally produced lactoferrin may bathe the ocular surface and sequester iron from potential pathogens.

    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).

    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.

    Uterine necrosis is a rare life-threatening condition known to be related to cesarean section, endometritis or uterine artery embolization. We present a case of uterine necrosis not preceded by common causative factors, diagnosed by computed tomography (CT) in a 64-year-old woman with myelodysplastic syndrome. A gas-filled, nonenhancing uterus was noted, diagnostic of uterine necrosis. At laparotomy, a nonvital uterus was removed. Imaging findings of uterine necrosis have sparsely been reported and mostly focus on magnetic resonance imaging technique. In this report, we describe the CT findings of uterine necrosis.

    To determine the, incidence, etiology, management, maternal, and fetal outcome and to evaluate trends in our area and recommend preventable measures. This prospective study is done between Jan 2012 and Aug 2013 in Pt. J.N.M. Medical College Raipur. All the women who had ruptured uterus were included. Relevant history was taken, women were assessed, adequate intervention done, and were followed up till 6 months after discharge. A total number of deliveries were 11,323. Out of 11,323 deliveries, 9,844 women were without prior LSCS, 1,479 women were with prior LSCS. A total of 40 cases of rupture uterus were there 25 in women with prior LSCS and 15 in women without LSCS. Thus, incidence among women with prior LSCS was 1.69 % and for women without LSCS was 0.152 %. Overall incidence of uterine rupture was 0.35 %. Major risk factors found were unbooked status (92.5 %), injudicious use of oxytocin (52.5 %), and unjustified VBAC trial (44 %). Bladder injury was found in 20 %. Extension to cervix was found commonly in uterus with no previous section (46.66 %). Blood transfusion was required in 92.5 %. Perinatal mortality was 85%. Only one maternal death was there (2.5%). Developed countries have incidence of uterine rupture 0.000 % in women without LSCS and 1 % in women with prior LSCS[1]. Thus, by directly comparing, our study of 20 month revealed that women stand 1,500 times higher risk for rupture even without previous cesarean section and 1.7 times in women with previous section in comparison to the developed countries. The overall burden of women with previous section being admitted for delivery is 12.28 %. 62.50 % women who had rupture uterus were those with previous section. Thus, careful selection of these women for trial of labor and a compulsory institutional delivery is recommended. We recommend use of oxytocin in titrated dose which clearly indicated by an obstetrician only, and it should be a prescription drug strictly.

    Full Text Available MicroRNAs (miRNAs are small non-coding RNAs that act as regulators of gene expression at the post-transcriptional level. They play a key role in several biological processes. Their abnormal expression may lead to malignant cell transformation. This study aimed to evaluate the expression profile of 84 miRNAs involved in tumorigenesis in immortalized cells of myometrium (MM, uterine leiomyoma (ULM, and uterine leiomyosarcoma (ULMS. Specific cell lines were cultured and qRT-PCR was performed. Thirteen miRNAs presented different expression profiles in ULM and the same thirteen in ULMS compared to MM. Eight miRNAs were overexpressed, and five were underexpressed in ULM. In ULMS cells, five miRNAs exhibited an overexpression and eight were down-regulated. Six miRNAs (miR-1-3p, miR-130b-3p, miR-140-5p, miR-202-3p, miR-205-5p, and miR-7-5p presented a similar expression pattern in cell lines compared to patient samples. Of these, only three miRNAs showed significant expression in ULM (miR-1-3p, miR-140-5p, and miR-7-5p and ULMS (miR-1-3p, miR-202-3p, and miR-7-5p. Our preliminary approach identified 24 oncomirs with an altered expression profile in ULM and ULMS cells. We identified four differentially expressed miRNAs with the same profile when compared with patients’ samples, which strongly interacted with relevant genes, including apoptosis regulator (BCL2, epidermal growth factor receptor (EGFR, vascular endothelial growth factor A (VEGFA, insulin like growth factor 1 receptor (IGF1R,serine/threonine kinase (RAF1, receptor tyrosine kinase (MET, and bHLH transcription factor (MYCN.

Although beef and dairy cattle are susceptible to BLV infection and BLV-associated lymphosarcoma, the disease is more commonly detected in dairy herds, mostly because of the management practices in dairy farms. The pathogenicity of BLV in its natural host, the bovine, depends mainly on the resistance/susceptibility genetics of the animal. The majority of infected cattle are asymptomatic, promoting the extremely high dissemination rate of BLV in many bovine populations. The important productive losses caused by the BLV, added to the health risk of maintaining populations with a high prevalence of infection with a retrovirus, generates the need to implement control measures. Different strategies to control the virus have been attempted. The most effective approach is to identify and cull the totality of infected cattle in the herd. However, this approach is not suitable for herds with high prevalence of infection. At present, no treatment or vaccine has proven effective for the control of BLV. Thus far, the genetic selection of resistant animals emerges as a natural strategy for the containment of the BLV dissemination. In natural conditions, most of the infected, resistant cattle can control the infection, and therefore do not pass the virus to other animals, gradually decreasing the prevalence of the herd.

    Full Text Available Today, there still exists a controversial issue, as to the high incidence of early embryonic death in mares, mated on the first post partum oestrus. The purpose of this study was first, to determine the post partum period of uterine involution in fine pace Colombian mares using endometrial cytology and ultra sonograph. Secondly, to determine the relation between the neutrophil percentages found in cytology and the echogenicity of accumulated intrauterine fluid during the first 30 post partum days. Twenty (n=20 mares were examined beginning on the 6th post partum day and on alternate days, up to the 30th day. All subjects were grazing Kikuyo grass (Pennisetum clandestinum at la Sabana de Bogotá, 2.600 meters over sea level, 4 º north latitude and with an average temperature of 13 º C. From the 3rd postpartum day, all 20 mares were exposed to 2 healthy stallions, to establish their heat behaviour. Ten of them, following complete randomization, were inseminated on the first postpartum heat, while the others were inseminated on the second post partum heat. Genital examination was carried out by a technician, who did not know the reproductive history of any of the experimental mares. Examinations included rectal palpation, ultra sonograph (Pie Medical 480, linear array, 5 MHz, vaginal swabs and endometrial cytology. Uterine dimension was recorded by rectal palpation and ultra sonograph, it was included the uterine horn dimensions (tip, middle, and corporo-cornual junction of previously gravid and non gravid uterus. Intrauterine fluid detection was performed by the use of an echogenicity scale. Ovaric structures were recorded (preovulatory follicles and ovulation. Pregnancy diagnosis was performed on day 15 post ovulation and then confirmed on day 40. Endometrial cytology samples were taken from uterus after the perineal area was disinfected using non covered isopos with a Pollanski speculum. Smears specimens were fixed with metil alcohol for 15

    Full Text Available Uterine arteriovenous malformation (AVM is a potentially life-threatening condition characterized by abrupt and profuse uterine bleeding from abnormal connections between arteries and veins in the myometrium. It is commonly associated with prior pregnancy or uterine trauma. We present a case of severe uterine AVM treated with danazol and transarterial embolization (TAE. A 38-year-old patient with a history of two abortions and a myomectomy was referred to our hospital for intermittent massive uterine bleeding. She was diagnosed with uterine AVM by transvaginal color Doppler ultrasonography and helical computed tomography (CT. Diagnostic three-dimensional CT (3D-CT angiography clearly demonstrated hypervascular tangles of uterine vessels, feeding arteries, remarkably dilated draining veins, as well as early filling of the internal iliac vein and the inferior vena cava, indicating massive arteriovenous shunting in the uterus. Danazol was administrated for 10 months to reduce the shunting of the uterine AVM before TAE with N-butyl-cyanoacrylate of the left ovarian artery and left uterine artery was successfully performed. After the procedure, we confirmed that shunting through the uterine AVM was markedly reduced. The patient has not experienced any severe uterine bleeding since the treatment.

    Uterine arteriovenous malformation (AVM) following gestational trophoblastic neoplasia (GTN) is a rare condition. It can be associated with chronic vaginal bleeding or life-threatening heavy bleeding, even after complete resolution of the tumor following chemotherapy. This analysis aimed to perform an extensive systematic review highlighting clinical symptoms, imaging, management and prognosis of this rare complication of GTN. We also describe an additional case of uterine AVM following GTN. We conducted a literature search using Medline, Embase and Cochrane library to analyze the clinical data of 49 published cases of uterine AVM following GTN. Median age of the women diagnosed with AVM was 29 years (range 15-49). Median gravidity was 2 (range 1-8) and 50% of women were nulligravida. Complete molar pregnancy was the most common initial gestational trophoblastic diagnosis (48%). Overall, 44 patients (88%) were symptomatic and presented with chronic or acute abnormal vaginal bleeding. Only 3 patients had an undetectable HCG level at the time of uterine AVM diagnosis. Hypo-echoic space in the myometrium is the most relevant finding on ultrasonography but the gold standard for the definitive diagnosis of AVMs is angiographic examination. Uterine artery embolization was the most common treatment option performed in 82% of the patients and was successful in controlling the bleeding in 85% of cases. We identified 20 pregnancies after successful embolization of uterine AVM following a GTN and 90% of them were successful. Because of the risk of life-threatening heavy bleeding, the diagnosis of uterine AVM should always be considered in patients with a history of recurrent unexplained vaginal bleeding after gestational trophoblastic neoplasia. Angiographic embolization is successful in the majority of cases and does not appear to compromise future pregnancy. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    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.

    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.

    To show the removal of an intramyometrial fetus after uterine curettage using laparoscopy as a safe surgical technique that offers excellent results and fewer complications than laparotomy. Presentation of the clinical case and step-by-step explanation of the technique. Uterine curettage is a frequently performed gynecologic abortion procedure. Dilatation and curettage is considered to be a safe surgical technique, with a low percentage of complications. The most common is uterine perforation, with higher risks in advanced gestational age, retroflexed uterus, or uterine leiomyomas. After institutional review board approval, we present the case of a 29-year-old women referred to our hospital from another clinic with a suspected uterine perforation after an elective curettage for a 14-week pregnancy. She presented with moderate abdominal pain. Vaginal ultrasound revealed intramyometrial fetal parts on isthmus and right parametrium and minimal free fluid in the pouch of Douglas. A laparoscopic approach was chosen. After a complete revision of the abdominal cavity, the right paravesical space was dissected, confirming no right uterine artery or ureter injury. One cavity was objectified in the posterior leaf of the broad ligament related to a uterine perforation and containing fetal bone parts, which were removed. The myometrial defect and the peritoneum were closed with intracorporeal sutures. The removal of fetal parts was done with a surgical glove thimble. After the procedure, the patient was treated with clindamycin and gentamycin, with a satisfactory recovery. The presence of an intramyometrial fetus is not a common complication of curettage. The use of laparoscopy is feasible and offers excellent results and advantages versus laparotomy regarding its treatment. Copyright © 2015 AAGL. Published by Elsevier Inc. All rights reserved.

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

    Uterine leiomyomas (fibroids) are common benign tumors which may cause heavy or painful periods, may present as a pelvic mass and are associated with infertility. Local excision of symptomatic lesions can be difficult and hazardous, and the alternative is hysterectomy. We are investigating interstitial laser photocoagulation (ILP) as a less invasive alternative. Initial experiments were undertaken on 40 fibroids after surgical removal. One or two bare tipped, precharred fibers from a 25 W semiconductor laser (805 nm) were inserted into the center of the fibroid and treatment delivered with 2 - 10 W for 100 - 1000 sec. Specimens were subsequently sectioned perpendicular to the fiber track. Fibroids are very pale and apart from occasional charred tracts there was little evidence of thermal coagulation macroscopically or after haematoxylon and eosin staining. However, using a diaphorase stain technique we were able to demonstrate ellipsoid zones of devitalized tissue up to 20 mm across (15 mm for single fibers). These results suggest that ILP is producing gentle, uniform coagulation which could lead to resorption of treated areas. With appropriate numbers of treatment sites, this could permit minimally invasive management of clinically significant lesions. Clinical studies have commenced treating fibroids with ILP at the time of surgical excision by myomectomy or hysterectomy.

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

    Intra-uterine device (IUD) is one of the birth control methods, which is available for nulliparous women, even though misconceptions still remain in medical or popular opinion. Only 1.3 % of nulliparous have a IUD as contraception in France while it is the second methods used by all women, after pill. The best contraception is the one chosen by women; however, the choice for a nulliparous of an IUD may be really difficult, despite the increasing number of women wishing to use it. Long-acting reversible contraceptives utilization, including IUD, is probably one of the issues to decrease the unintended pregnancies. An exhaustive and clear information about IUD is necessary to allow an informed and real choice. This prescription must consider contraindications and medical conditions for safe insertion, especially to avoid infection by screening STD (Chlamydia trachomatis and Nesseria gonorrhoeae) in nulliparous women<25 years old. Insertion must be effected with usual precautions and short or SL IUD preferred. Even if side effects such as expulsion, pelvic pains or dysmenorrhea are more frequent by nulliparous, IUD is a first intention choice for contraception to be consider, that women could obtain easily, including in emergency contraception situation.

    Full Text Available The aim of our study was to develop a vitrification carrier for bovine oocyte cryopreservation. The carrier was to be cheap enough, elementary in its construction and meet contemporary requirements for a safe closed system. In a closed system, a cell is prevented from direct exposure to liquid nitrogen, thus minimizing the risk of cross-contamination. Furthermore, two questions regarding the proper vitrification technique were resolved: if it is necessary to partially denude the oocytes before the vitrification process or whether intact cumulus oocyte complexes should be frozen; and if it is more advantageous to preheat the vitrification solutions to female body temperature (39 °C or to keep them at room temperature. Our results show that it is better to partially denude the oocytes prior to vitrification because cryopreserved intact cumulus oocyte complexes often proved dark, non-homogeneous or fragmented cytoplasm after warming, with many of them having visibly widened perivitelline spaces or fractured zonae pellucidae as a result of extensive damage during vitrification. Consequently, intact cumulus oocyte complexes showed significantly lower numbers of cleavage stage embryos on Day 3 compared to partially denuded oocytes (7.4% and 26%, respectively. On the other hand, the survival rate and following development of fertilized oocytes in preheated vitrification solution were equal to results reached at room temperature conditions. In conclusion, results achieved with the newly developed carrier were comparable to previously published studies and therefore they could be recommended for common use.

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

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

    A 5-year-old intact female Maine Coon cat presented with a 2 day history of lethargy, anorexia and anaemia. The cat had bred 60 days previously and jumped from a height 3 days earlier, which was followed by a worsening of its condition. Ultrasonography revealed that two fetuses had died and one remained alive. Urgent surgical intervention was deemed necessary, and the cat underwent a blood transfusion and laparotomy. The right uterine horn was dark red in appearance and had rotated 360° in the clockwise direction at its base. Subsequently, an ovariohysterectomy and caesarean section were performed, and the fetus in the left uterine horn initially survived. Although the cat appeared to recover from anaemia and physical injury, the kitten died on postoperative day 1. In cases involving only one twisted uterine horn, the fetuses located in the contralateral horn could potentially survive; however, many such fetuses do not survive, and only a few reports have described fetal survival in a pregnant cat with uterine torsion. In the present case, early surgical intervention and blood transfusion allowed us to save the cat. Our findings demonstrate the life-saving abilities of initial support treatment and early surgical intervention for both the pregnant cat and fetuses in cases of acute abdomen caused by uterine torsion.

    To evaluate maternal outcomes following uterine balloon tamponade in the management of postpartum hemorrhage. Retrospective case-series. Two French hospitals, a level 3 university referral center and a level 2 private hospital. All women who underwent balloon tamponade treatment for primary postpartum hemorrhage. Uterine tamponade was used after standard treatment of postpartum hemorrhage had failed. The study population was divided into two groups, successful cases where the bleeding stopped after the balloon tamponade, and failures requiring subsequent surgery or embolization. Success rates. Uterine tamponade was used in 49 women: 30 (61%) after vaginal delivery and 19 (39%) after cesarean section. Uterine atony was the main cause of hemorrhage (86%). The overall success rate was 65%. Of 17 failures, surgery was required in 16 cases, including hysterectomy in 11, and uterine artery embolization in one case. Demographic and obstetric characteristics did not differ significantly between the success and failure groups. No complications were directly attributed to the balloon tamponade in the postpartum period. Two women had a subsequent full-term pregnancy without recurrence of postpartum hemorrhage. Balloon tamponade is an effective, safe and readily available method for treating primary postpartum hemorrhage and could reduce the need for invasive procedures. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

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

    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.

    To evaluate the frequency of uterine rupture following induction of labor in women with a previous cesarean section. Misoprostol was compared to other methods of induction. A retrospective cohort study of 208 women attempting induction of labor after one previous cesarean section. Delivery data were collected retrospectively and compared. Group 1(2009-2010) was compared with Group 2 (2012-2013). In Group 1, the main method of induction was vaginal PGE2 (prostaglandin-E2), amniotomy, oxytocin or a balloon catheter. In Group 2, the dominant method of induction was an oral solution of misoprostol. frequency of uterine rupture in the two groups. Nine cases (4.3%) of uterine rupture occurred. There was no significant difference in the frequency of uterine rupture following the change of method of induction from PGE2, amniotomy, oxytocin or mechanical dilatation with a balloon catheter to orally administered misoprostol (4.1 versus 4.6%, p = 0.9). All ruptures occurred in women with no prior vaginal delivery. The shift to oral misoprostol as the primary method of induction in women with a previous cesarean section did not increase the frequency of uterine rupture in the cohort studied.

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

    Full Text Available The taeniasis-cysticercosis complex is a long known zoonotic parasitosis characteristic of underdeveloped countries. In addition to its public health significance, this parasitosis is cause of economic losses to the beef production chain, and synonymous of technical inadequacy in relation to the adoption of Good Agricultural Practices. The occurrences of both human teniasis and bovine cysticercosis could and should be controlled with basic sanitary measures. However, there is much variation in the occurrence of the disease in cattle, characterizing a low rate of technical development as well as problems related to the adoption of basic sanitation measures. This review describes, in details, the causative agent and its epidemiological chain, besides raising current information about the occurrence of bovine cysticercosis in different regions of Brazil, aiming at the adoption of prophylactic measures by different segments responsible.

    Congenital uterine abnormalities are common and may be associated with developmental renal abnormalities. Mutations of the hepatocyte nuclear factor-1β (HNF1B) gene are associated with renal and uterine abnormalities. We aimed to study the role of HNF1B mutations in a cohort with congenital uterine abnormalities. We tested 108 probands with uterine abnormalities for HNF1B mutations. We collected clinical information from patient records. Nine of 108 women (8%) had a mutation or deletion in the HNF1B gene. Abnormal HNF1B was found in 18% of the 50 probands who had both uterine and renal abnormalities but in none of the 58 women with isolated uterine abnormalities. Mutations of the HNF1B gene are found in women with both uterine and renal abnormalities but are rare in isolated uterine abnormalities. We suggest that HNF1B testing should be performed in patients with both renal and uterine abnormalities, but not in patients with isolated uterine abnormalities. Copyright © 2010 Mosby, Inc.

    Uterine arteriovenous malformation (AVM) is a rare disease. Percutaneous transcatheter uterine arterial embolization (UAE) has been performed in patients who wish to preserve their ability to conceive. UAE is considered to be a safe and effective procedure, but its long-term effect on fertility has not been fully elucidated. We present a case of ectopic tubal pregnancy after conservative treatment with UAE for uterine AVM. A 30-year-old Japanese woman was admitted for the treatment of unruptured right tubal pregnancy at 6 weeks of gestation. She had conceived spontaneously and delivered a healthy baby at term, 3 years previously. Subsequently, she was successfully treated with UAE for a large congenital uterine AVM. Transvaginal color Doppler ultrasonography revealed no evidence of residual AVM vessels. After the diagnosis of ectopic pregnancy, the patient underwent right tubectomy. At laparotomy, there were no adhesions or structural anomalies in the pelvic cavity that might affect tubal function. The patient's postoperative course was uneventful, and she is now healthy without conception 24 months after surgery. Prior uterine arterial embolization may have affected the tubal function in the present case, allowing tubal pregnancy to occur.

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

    Uterine fibroids are the most common benign uterine tumors in women of reproductive age. Although most women are asymptomatic (80%), fibroids, according to their type and location, can cause several symptoms and impact quality of life. To date, no medical treatment is able to eliminate fibroids. Ulipristal acetate (UPA) is an orally active synthetic selective progesterone receptor modulator (SPRM) characterized by a tissue-specific progesterone antagonist effect that reduces the proliferation of leiomyoma cells and induces apoptosis. It was licensed in Europe for preoperative fibroid treatment in 2012. Its pharmacological and pharmacodynamic characteristics, its efficacy and good tolerance make UPA a new important tool in the management of uterine fibroids.

    Uterine arteriovenous malformation (AVM) is a rare condition and can be life-threatening if not managed properly. We report a case that was diagnosed by typical ultrasound imaging and treated successfully with uterine arterial embolization. A 28-year-old female, gravida 4, para 3, abortus 1, presented with massive vaginal bleeding 19 days after a termination of pregnancy due to fetal anomaly. After a dilatation and curettage 3 years previously, typical ultrasound image findings and a declining pattern of serum beta-hCG (human chorionic gonadotrophin), acquired AVM was highly suspected. The patient underwent bilateral uterine arterial embolization. Four weeks later, there was nearly complete resolution of the AVM and the patient's menstrual cycle was restored 6 weeks after embolization. AVM can be diagnosed at an early stage with the aid of history taking and ultrasound. Percutaneous embolotherapy is a safe and effective treatment for AVM, especially when fertility preservation is desired.

    Uterine arteriovenous malformation (AVM) is a rare disease. Percutaneous arterial embolization has been performed for patients who wish to preserve their ability to conceive. A 27-year-old primigravida was admitted for treatment of threatened premature labor at 21 weeks of gestation. She had been diagnosed with asymptomatic uterine AVM 2 years previously. She had not received any treatment before conception. At 41 weeks of gestation she spontaneously delivered a healthy infant weighting 3,154 g. and the Excessive bleeding (1,600 mL) occurred, probably due to eruption of the AVM vessel at the time of parturition. At 3 months postpartum, the patient underwent arterial embolization of AVM. The management of uterine AVM should be individualized, taking into account the patient's desire to maintain her fertility and the symptoms.

    Uterine leiomyosarcoma (uLMS) is a rare mesenchymal tumor of the gynecologic tract. Although diagnosed in only 1-3% of patients with uterine cancer, uLMS accounts for the majority of uterine cancer-related deaths. The standard of care for patients with uLMS includes total hysterectomy and bilateral salpingo-oophorectomy (BSO). There are no standard recommendations regarding adjuvant or palliative therapy. Many cytotoxic and targeted agents have been studied in clinical trials in an effort to identify an effective therapy that may alter the natural history of this disease. Unfortunately, as of now, there are no adjuvant therapy regimens that improve overall survival in this patient population. There is, therefore, an unmet need to identify a novel therapy that will improve the survival of women diagnosed with this aggressive disease. Here we summarize the existing literature on adjuvant therapy in uLMS, specifically highlighting advances made in the last 5 years.

    Current methodologies to assess the process of labor, such as tocodynamometry or intrauterine pressure catheters, fetal fibronectin, cervical length measurement and digital cervical examination, have several major drawbacks. They only measure the onset of labor indirectly and do not detect cellular changes characteristic of true labor. Consequently, their predictive values for term or preterm delivery are poor. Uterine contractions are a result of the electrical activity within the myometrium. Measurement of uterine electromyography (EMG) has been shown to detect contractions as accurately as the currently used methods. In addition, changes in cell excitability and coupling required for effective contractions that lead to delivery are reflected in changes of several EMG parameters. Use of uterine EMG can help to identify patients in true labor better than any other method presently employed in the clinic. PMID:21241260

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

  18. The Hilbert Transform in Analysis of Uterine Contraction Activity

    2015-12-01

    Full Text Available Prevention and early diagnosis of forthcoming preterm labor is of vital importance in preventing child mortality. To date, our understanding of the coordination of uterine contractions is incomplete. Among the many methods of recording uterine contractility, electrohysterography (EHG – the recording of changes in electrical potential associated with contraction of the uterine muscle, seems to be the most important from a diagnostic point of view. There is some controversy regarding whether EHG may identify patients with a high risk of preterm delivery. There is a need to check various digital signal processing techniques to describe the recorded signals. The study of synchronization of multivariate signals is important from both a theoretical and a practical point of view. Application of the Hilbert transformation seems very promising.

    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.

    Vaginal septa and associated mullerian anomalies can be difficult to diagnose and manage. This case series intends to educate the readers about the benefits and limitations of radiologic techniques both for the investigation as well as for the surgical management of these cases. It also seeks to inform them about a unique combination of vaginal and uterine anomalies known as Herlyn-Werner-Wunderlich syndrome. Three cases were discussed, each with a different presentation. All of the cases included obstructed right hemivagina and right renal agenesis. One case was associated with uterine septum and the other 2 cases were associated with uterus didelphys. The correct diagnosis of associated uterine anomalies in patients presenting with vaginal septa can be challenging. Diagnosis solely based on imaging should be cautioned because of its limitations. Use of ultrasound in the operating room can be a valuable tool.

    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.

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

    Over the past decade an increasing demand for uterine-sparing treatment to manage symptomatic uterine myomas has become apparent in women's health care. A preliminary report showed that radiofrequency ablation (RFA) of uterine fibroids under laparoscopic guidance was a safe and effective minimally invasive approach with encouraging short-term results. The purpose of this study was to evaluate the midterm outcomes of radiofrequency ablation (RFA) of uterine myomas in terms of durability of symptom control and level of health-related quality of life. Consecutive women with symptomatic uterine myomas, no plans for future pregnancy, and who declined hysterectomy were offered RFA ablation of uterine fibroids under laparoscopic guidance. Only 25 patients who completed at least the one-year follow-up assessment were included in the study group. Follow-up evaluations were scheduled at 1, 3, 6, 9, and 12 months and thereafter annually following the procedure. Improvement in myoma-related symptoms and impact on quality of life were assessed using a validated questionnaire (UFS-QOL). The median number of myomas treated per patient was 1 (range = 1-3). The median baseline volume of the dominant myoma was 76.8 cm3 (range = 14.8-332.8). No intraoperative or postoperative complications occurred. The median follow-up time was 24 months, with nine women completing three years of follow-up. The median reduction in myoma volume was 68.8% and 77.9% at six months and one year, respectively. No further change in fibroid size was observed at two years and three years. One year after the procedure, one woman (4%) underwent hysterectomy for recurrence of fibroid-related symptoms. Quality-of-life measures showed significant and durable improvement compared with baseline. RFA of symptomatic fibroids seems a valuable alternative to major surgery, with durable symptom relief for most patients and a low chance of recurrence at midterm.

    To facilitate the planning of future resources for cancer services in Ontario, Cancer Care Ontario commissioned an evaluation of operative services delivered for uterine cancer. Women with an incident diagnosis of a uterine malignancy were identified from 1 April 2003 to 31 March 2004 using the Ontario Cancer Registry. Record linkages were created to other provincial health databases such as the Ontario Health Insurance Plan. Uterine cancer affected 1,436 women. Disease specific rates of cancer were higher in rural areas and those from the highest income quintiles. Surgery occurred in 94.7% of women. Use of surgery did not appear to vary by SEC, urban/rural residence or LHIN. Gynecologists conducted 76.1% of the operations. Lymphadenectomy took place in 18.7% of women. Lymphadenectomy rates were highest in gynecologic oncologists (43.3%). All women were assessed by CXR. Radiation therapy consults were preformed in half of the women with uterine cancer but treatment was only delivered in half of those seen. Medical oncologists saw about 6.3% of women with uterine cancers. There appear to be variations in incidence rates of uterine cancer with disease being more frequent in those of the highest SES. In two-thirds of the population, surgery is delivered in the region where the patient lives. Subspecialty care from gynecologic oncologists was provided to one-third of women. Rates of lymphadenectomy as part of a surgical attempt to assess disease spread appear low. These pilot data would be enhanced with further information such as comorbidity, treatment intent (palliative/curative), histology, grade and stage.

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

    To evaluate the effects of sequential continuous hormone replacement therapy (HRT) on myoma size and on pulsatility index (PI) of uterine arteries and to verify the correlation between uterine artery flow impedance and the growth rate of myoma in women receiving HRT. In a prospective 1-year study 60 postmenopausal women were enrolled into three study-groups to receive continuous transdermal 17beta-oestradiol 0.05 mg/day plus nomegestrolo acetate 5 mg/day sequentially added: 20 patients (group A) unaffected by uterine myomas, 20 patients (group B) with single asymptomatic myoma 3 cm/14 cm3. The changes in myoma volume and in PI were assessed by means of transvaginal ultrasonographic scan every 3 months. The patients with myoma were divided into two subgroups: quiescent myoma (B1, C1) and growing myoma (B2, C2). No significant increase of uterine fibroids volume was found after 1-year HRT (24.14+/-20.02-->28.81+/-30.02 cm3). Six out of eight myomas growing during HRT belonged to group C. The uterine artery basal PI value of group A was significantly higher (P1.88+/-0.16) and C (1.59+/-0.28-->1.92+/-0.21). The baseline PI values in group B1 and C1 were significantly higher than the baseline values observed in group B2 and C2 (1.76+/-0.17 vs. 1.32+/-0.02, 1.76+/-0.16 vs. 1.24+/-0.08) and significantly lower than those observed in group A (2.39+/-0.47). After 3 months of HRT, the PI values were not significantly higher than the baseline values in groups B1 and C2 (1.76+/-0.17-->1.90+/-0.17; 1.24+/-0.08-->1.74+/-0.16), while they were significantly higher in group C1 (1.76+/-0.16-->2.01+/-0.17). Sequential continuous HRT does not increase the volume of the uterine myoma. The findings of very low resistance index in the uterine arteries of women with growing myoma may indicate the risk of growth of the neoplasia during HRT. The assessment of PI in the uterine arteries could be helpful in predicting the growth rate of the myomas before starting HRT.

    A 21-year-old woman with history of presacral ganglioneuroblastoma underwent I-MIBG scan for restaging. Planar images revealed increased MIBG activity in the upper pelvis, suggestive of disease recurrence. Complementary SPECT/CT images, however, localized the activity to the uterine cervix. Upon further questioning, it has been established that the patient was menstruating. Subsequent follow-up scans proved normal, confirming the benign etiology of these findings. The case shows that radioactive blood accumulation in the uterine cervix can interfere with MIBG scan interpretation in menstruating patients.

    Abnormal uterine bleeding (AUB) is one of the commonest health problems encountered by women and a frequent phenomenon during menopausal transition. The clinical management of AUB must follow a standardized classification system to obtain the better diagnostic pathway and the optimal therapy. The PALM-COEIN classification system has been approved by the International Federation of Gynecology and Obstetrics (FIGO); it recognizes structural causes of AUB, which can be measured visually with imaging techniques or histopathology, and non-structural entities such as coagulopathies, ovulatory dysfunctions, endometrial and iatrogenic causes and disorders not yet classified. In this review we aim to evaluate the management of nonstructural causes of AUB during the menopausal transition, when commonly women experience changes in menstrual bleeding patterns and unexpected bleedings which affect their quality of life.

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

Large, in-depth survey investigating patients' motivations, aims, and beliefs on UTx. Imperial College London. Women diagnosed with absolute uterine factor infertility (AUFI) who were seeking information on UTx and had already volunteered to participate in the study. A semistructured interview involving a brief baseline questionnaire before a Q&A session and a 20-minute video exploring the main risks and benefits for UTx. Attitudes of self-referred patients with AUFI toward UTx before and after education focusing on UTx. Rank order of importance of key UTx-related issues. Forty women were interviewed. Following the video presentation and Q&A session, 97.5% (n = 39) would undergo UTx ahead of surrogacy and adoption in full knowledge that the latter 2 options would be ultimately safer for their own well-being and the fact that the graft could fail even prior to conception. All felt that UTx should take place, and 92.5% saw UTx as achievable. The study demonstrates a keen interest in UTx, partly because other options seem difficult to access. It is worth noting that people appear to be distancing themselves from the risk. This requires careful assessment in any clinical program. This study is the first to demonstrate a qualitative relationship between patients with AUFI and their curiosity and desire for UTx. It paves the way for forming the introduction into the psychological assessment of a potential patient. © 2016, NATCO.

    2008-01-01

    Full Text Available It is well known that focused ultrasound has a biologic effect on tissue. High intensity focused ultrasound (HIFU on a small target area raises the temperature of the tissue enough to denaturate proteins and cause irreversible cell damage. The tight focus of the ultrasound energy allows delivery of the intended dose to a very precise location. The resulting coagulation necrosis is relatively painless. The application of this method in the human clinical setting has required pilot studies on an animal model. Although the treatment had a high success rate, there was a significant percentage of complications, mainly attributed to the technical drawbacks of the procedure. Therefore, this method has been modified for use in humans, and the HIFU is now guided, monitored and controlled by magnetic resonance imaging (MRI. In October 2004, Food and Drug Adiministration (FDA approved MRI guided focused ultrasound treatment of uterine fibroids in humans. Since then, successful treatment of uterine myomas by HIFU has been performed in thousands of women.

    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. Published by Elsevier Inc.

    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.

    To record and characterize electromyography (EMG) from the uterus and abdominal muscles during the nonlabor to first and second stages of labor and to define relationships to contractions. Nulliparous patients without any treatments were used (n = 12 nonlabor stage, 48 during first stage and 33 during second stage). Electromyography of both uterine and abdominal muscles was simultaneously recorded from electrodes placed on patients' abdominal surface using filters to separate uterine and abdominal EMG. Contractions of muscles were also recorded using tocodynamometry. Electromyography was characterized by analysis of various parameters. During the first stage of labor, when abdominal EMG is absent, uterine EMG bursts temporally correspond to contractions. In the second stage, uterine EMG bursts usually occur at same frequency as groups of abdominal bursts and precede abdominal bursts, whereas abdominal EMG bursts correspond to contractions and are accompanied by feelings of "urge to push." Uterine EMG increases progressively from nonlabor to second stage of labor. (1) Uterine EMG activity can be separated from abdominal EMG events by filtering. (2) Uterine EMG gradually evolves from the antepartum stage to the first and second stages of labor. (3) Uterine and abdominal EMG reflect electrical activity of the muscles during labor and are valuable to assess uterine and abdominal muscle events that control labor. (4) During the first stage of labor uterine, EMG is responsible for contractions, and during the second stage, both uterine and abdominal muscle participate in labor.

    2016-01-01

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

    2006-09-01

    The effect of gonadotropin-releasing hormone agonist (GnRHa) on uterine arteriovenous malformations (AVM) is not well known. A 37-year-old woman with a previous cesarean was diagnosed as having a uterine AVM after a spontaneous abortion with massive vaginal bleeding. The AVM decreased in size from 5.1 x 3.8 cm to 1.4 x 1.0 cm after 6 months of therapy with a GnRHa. Uterine artery embolization conducted after the GnRH therapy resulted in complete disappearance of the AVM. The patient's menstrual cycles and ovulation resumed 3 months after uterine artery embolization. Gonadotropin-releasing hormone agonist therapy reduced the size of the uterine AVM. Thus, GnRHa therapy may be useful for uterine AVM in situations where uterine artery embolization must be postponed.

    2017-01-01

    Full Text Available Background: to assess the efficiency of uterine compression sutures in treatment of severe postpartum hemorrhage. Materials and methods: 55 patients who had been performed cesarean section from 2013 to 2015 were examined. The basic group included 25 patients with uterine compression sutures that had been performed to stop severe postpartum hemorrhage, the control group – 30 patients without severe postpartum hemorrhage. The main outcome measures were the ability to stop hemorrhage, complications of postpartum period and the assessment of the uterine cavity by hysteroscopy. Results: uterine compression sutures stopped postpartum hemorrhage in 19 of 25 cases (76%. None of the women developed postpartum period complications related to the procedure. Ten women underwent hysteroscopy after uterine compression sutures. Two women (20% had ligature in the uterine cavity. Conclusion: Our results suggest that uterine compression sutures is an effective and safe treatment for postpartum haemorrhage.

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

  12. Diagnosis of Acquired Uterine Arteriovenous Malformation by Doppler Ultrasound.

    Scribner, Drew; Fraser, Robert

    2016-08-01

    Acquired uterine arteriovenous malformation (AVM) is a rare cause of postpartum vaginal bleeding and can often be confused with retained products of conception (RPOC). Certain findings on ultrasound (US) increase the likelihood for AVM, such as hypoechoic areas in the myometrium and high velocity, multidirectional blood flow. Recognizing these changes on bedside US can cue the physician to send the patient for further studying and lead to the correct diagnosis. A 31-year-old, multigravida, multiparous female presented 5 weeks post-cesarean section with heavy, intermittent vaginal bleeding. Patient had multiple previous visits for similar bleeding, including an evaluation for RPOC. Upon current presentation, the patient underwent an US in the emergency department with color and pulse wave Doppler. US revealed a hypoechoic area within the myometrium, with high velocity, bidirectional blood flow, raising the clinical suspicion for uterine AVM. Following confirmatory studies, the patient underwent successful embolization of the AVM. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The proper diagnosis of AVM is crucial, because the primary treatment modality for the alternative diagnosis of RPOC (i.e., dilation and curettage) can worsen vaginal bleeding and lead to shock or death, and is therefore contraindicated for uterine AVM. US is a quick bedside tool that can be used for rapid diagnosis of uterine AVM. Copyright © 2016 Elsevier Inc. All rights reserved.

  13. Maternal obesity drives functional alterations in uterine NK cells.

    Over one-fifth of North American women of childbearing age are obese, putting these women at risk for a variety of detrimental chronic diseases. In addition, obesity increases the risk for developing major complications during pregnancy. The mechanisms by which obesity contributes to pregnancy complications and loss remain unknown. Increasing evidence indicates that obesity results in major changes to adipose tissue immune cell composition and function; whether or not obesity also affects immune function in the uterus has not been explored. Here we investigated the effect of obesity on uterine natural killer (uNK) cells, which are essential for uterine artery remodeling and placental development. Using a cohort of obese or lean women, we found that obesity led to a significant reduction in uNK cell numbers accompanied with impaired uterine artery remodeling. uNK cells isolated from obese women had altered expression of genes and pathways associated with extracellular matrix remodeling and growth factor signaling. Specifically, uNK cells were hyper-responsive to PDGF, resulting in overexpression of decorin. Functionally, decorin strongly inhibited placental development by limiting trophoblast survival. Together, these findings establish a potentially new link between obesity and poor pregnancy outcomes, and indicate that obesity-driven changes to uterine-resident immune cells critically impair placental development.

    Background: Mediator complex participates in transcriptional regulation by connecting regulatory DNA sequences to the RNA polymerase II initiation complex. Recently, we discovered through exome sequencing that as many as 70% of uterine leiomyomas harbour specific mutations in exon 2 of mediator complex subunit 12 (MED12). In this work, we examined the role of MED12 exon 2 mutations in other tumour types. Methods: The frequency of MED12 exon 2 mutations was analysed in altogether 1158 tumours by direct sequencing. The tumour spectrum included mesenchymal tumours (extrauterine leiomyomas, endometrial polyps, lipomas, uterine leiomyosarcomas, other sarcomas, gastro-intestinal stromal tumours), hormone-dependent tumours (breast and ovarian cancers), haematological malignancies (acute myeloid leukaemias, acute lymphoid leukaemias, myeloproliferative neoplasms), and tumours associated with abnormal Wnt-signalling (colorectal cancers (CRC)). Results: Five somatic alterations were observed: three in uterine leiomyosarcomas (3/41, 7% Gly44Ser, Ala38_Leu39ins7, Glu35_Leu36delinsVal), and two in CRC (2/392, 0.5% Gly44Cys, Ala67Val). Conclusion: Somatic MED12 exon 2 mutations were observed in uterine leiomyosarcomas, suggesting that a subgroup of these malignant tumours may develop from a leiomyoma precursor. Mutations in CRC samples indicate that MED12 may, albeit rarely, contribute to CRC tumorigenesis. PMID:23132392

    2017-07-01

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

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

    Directory of Open Access Journals (Sweden)

    Salvatore Giovanni Vitale

    2017-05-01

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

    2017-04-01

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

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

    The aim of the study is to analyze the use of vertical incision of the lower uterine segment when performing Caesarean section (CS). The study includes 89 pregnant women who delivered by CS. The main group includes 40 cases with vertical incision in lower uterine segment (preliminary intention, but final decision made during surgery) and controls--49 cases with transversal incision of lower uterus segment with difficulties/complications of fetus extraction (30 with uterine lacerations and 19 with T-form incision). The mean gestational age in the main group is 32 g.w. (range 26-39) vs. 31 in control group (27-39). RESULTS. Vertical incision of the uterus is performed in 57.5% due to prematurity and lack of enough space for transversal incision (lower uterine segment not yet formed), in 25 % the cause is situs transverses of the foetus and the rest of the cases are related with technical difficulties in isthmicotransversal approach (myoma praevia, anomalies of the uterus, adhesions of the omentum). C.S. is performed for mean 66 min. in the main group vs. 74 min. with controls (p uterus. Blood loss in main group is 664 ml, vs. 884 ml in control group (p trauma with better final outcome for the newborn.

    Frequency and strength of the uterine contractions monitoring enables to control the labour progress and also, although in a restricted way, to determine the beginning of labour, as long as it is not preterm. Mechanical approach provides only the low frequency signal, which describes the contractions more or less accurately, depending on whether an intrauterine pressure measurement is used in the former case or whether an external stress measurement is applied in the latter case. This signal does not comprise information on contractions characteristics and enables only to estimate their basic timing parameters. Description of the electrophysiological properties may be obtained only by means of the uterine electrical signals measurement. In the following paper, the classical interpretation of the uterine contraction activity which relies upon its mechanical and electrical activity was presented. Additionally, the frequency parameters provided exclusively by the electrical signal were proposed. The possibility of the electrohysterogram analysis may provide more complete information on uterine muscle functioning. Results of the research studies show that further development of electrohysterography will enable its wider application in pregnancy and labour diagnostics.

    This hermeneutical inquiry was aimed at understanding the experience of women with advanced uterine cancer and providing sociocultural data on hospice nursing for these Korean women. We adopted hermeneutic phenomenological approach of van Manen. The research question was "What do women with advanced uterine cancer experience in their life?". The data for this paper came from interviews with 11 participants between February, 2000 and May, 2001 and reviews of secondary text of essay and drama, poet, memorandum. Each informant was interviewed three or more times for 30 min.-2 hours. In the process of analysis we did reflective thinking and used line-by-line and highlighting analysis techniques. The substantial themes of illness experience of women in advanced uterine cancer were 'Endless suffering', 'In the midst of chaos and darkness,' 'on the wish of new possibility', 'finding new transformed self. Women with Advanced uterine cancer suffer with complex problems and wonder in the midst of chaos and darkness, but they find a new transformed self by the wish of new possibility and experience human becoming.

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

    2015-03-01

    Bovine Babesiosis in cattle is caused by the transmission of protozoa of Babesia spp. by ticks as vectors. Juvenile cattle (Bovine Babesiosis, rarely show symptoms, and acquire immunity upon recovery. Susceptibility to the disease varies between breeds of cattle. Models of the dynamics of Bovine Babesiosis transmitted by the cattle tick that include these factors are formulated as systems of ordinary differential equations. Basic reproduction numbers are calculated, and it is proved that if these numbers are below the threshold value of one, then Bovine Babesiosis dies out. However, above the threshold number of one, the disease may approach an endemic state. In this case, control measures are suggested by determining target reproduction numbers. The percentage of a particular population (for example, the adult bovine population) needed to be controlled to eradicate the disease is evaluated numerically using Columbia data from the literature.

    The purpose of this study was to describe patient preferences for uterine preservation and hysterectomy in women with pelvic organ prolapse symptoms and to describe predictors of preference for uterine preservation. This multicenter, cross-sectional study evaluated patient preferences for uterine preservation vs hysterectomy in women with prolapse symptoms who were being examined for initial urogynecologic evaluation. Before meeting the physician, the women completed a questionnaire that asked them to indicate their prolapse treatment preference (uterine preservation vs hysterectomy) for scenarios in which the efficacy of treatment varied. Patient characteristics that were associated with preferences were determined, and predictors for uterine preservation preference were identified with multivariable logistic regression. Two hundred thirteen women participated. Assuming outcomes were equal between hysterectomy and uterine preservation, 36% of the women preferred uterine preservation; 20% of the women preferred hysterectomy, and 44% of the women had no strong preference. If uterine preservation was superior, 46% of the women preferred uterine preservation, and 11% of the women preferred hysterectomy. If hysterectomy was superior, 21% of the women still preferred uterine preservation, despite inferior efficacy. On multivariable logistic regression, women in the South had decreased odds of preferring uterine preservation compared with women in the Northeast (odds ratio [OR], 0.17; 95% CI, 0.05-0.66). Women with at least some college education (OR, 2.87; 95% CI, 1.08-7.62) and those who believed that the uterus is important for their sense of self (OR, 28.2; 95% CI, 5.00-158.7) had increased odds for preferring uterine preservation. A higher proportion of women with prolapse symptoms who were examined for urogynecologic evaluation preferred uterine preservation, compared with hysterectomy.

    Leiomyosarcoma (LMS) is the most common uterine sarcoma. Although the disease is relatively rare, it is responsible for considerable mortality due to frequent metastasis and chemoresistance. The molecular events related to LMS metastasis are unknown to date. The present study compared the global gene expression patterns of primary uterine LMSs and LMS metastases. Gene expression profiles of 13 primary and 15 metastatic uterine LMSs were analyzed using the HumanRef-8 BeadChip from Illumina. Differentially expressed candidate genes were validated using quantitative real-time polymerase chain reaction (PCR) and immunohistochemistry. To identify differently expressed genes between primary and metastatic tumors, we performed one-way analysis of variance with Benjamini-Hochberg correction. This led to identification of 203 unique probes that were significantly differentially expressed in the 2 tumor groups by greater than 1.58-fold with P < .01, of which 94 and 109 were overexpressed in primary and metastatic LMSs, respectively. Genes overexpressed in primary uterine LMSs included OSTN, NLGN4X, NLGN1, SLITRK4, MASP1, XRN2, ASS1, RORB, HRASLS, and TSPAN7. Genes overexpressed in LMS metastases included TNNT1, FOLR3, TDO2, CRYM, GJA1, TSPAN10, THBS1, SGK1, SHMT1, EGR2, and AGT. Quantitative real-time PCR confirmed significant anatomical site-related differences in FOLR3, OSTN, and NLGN4X levels; and immunohistochemistry showed significant differences in TDO2 expression. Gene expression profiling differentiates primary uterine LMSs from LMS metastases. The molecular signatures unique to primary and metastatic LMSs may aid in understanding tumor progression in this cancer and in providing a molecular basis for prognostic studies and therapeutic target discovery.

    To study the aetiopathogenics, diagnostic and therapeutic aspects of this pathology. The authors report a series of 10 vesico-uterine fistulas observed over à 10 years period. The mean age was 32 years(30-40). The fistulas were secondary to cesarian section in 6 cases and to abnormal delivery in 4 cases. The symptomatology was an urinary leakage from the vagina in 6 cases, an isolated cyclic hematuria in 3 cases and the association of the two signs in one case. The diagnostic was established on clinical examination in 8 cases. Intraveinous urography was performed in all the patients and visualised the uterine cavity in only 8 cases. In the 2 remaining cases a retrograd cystography was performed and demonstrated the opacification of the uterine cavity. The treatment was surgical in 9 cases. One patient who had a menuria has refused the operation. The diagnostic of the vesico-uterine fistulas is often based on clinic examination but often necessitate recourse to complementary examinations mostly in the menouria forms. The intraveinous urography does not establish the diagnostic in all the cases but is an indispensable complementary investigation because it permits searching for an associated ureteral injury. With a mean recoil of one year the results judged on the disappearance of the clinic signs was good in all the patients. The vesico-uterine fistulas are often secondary to cesarian section or abnormal delivery. Their treatment is surgical but is above all preventive by the improvement of the obstetric taking care and avoiding the vesical injuries in the course of the cesarian section.

  19. Peritoneal dissemination complicating morcellation of uterine mesenchymal neoplasms.

    Directory of Open Access Journals (Sweden)

    Michael A Seidman

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

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

    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. © 2011 The Authors.

    The purpose of this study was to establish optimal conditions for the hydrolysis of bovine plasma protein. Response surface methodology was used to model and optimize responses [degree of hydrolysis (DH), 2,2-diphenyl-1-picrydrazyl (DPPH) radical-scavenging activity and Fe(2+)-chelating activity]. Hydrolysis conditions, such as hydrolysis temperature (46.6-63.4 °C), hydrolysis time (98-502 min), and hydrolysis pH (6.32-9.68) were selected as the main processing conditions in the hydrolysis of bovine plasma protein. Optimal conditions for maximum DH (%), DPPH radical-scavenging activity (%) and Fe(2+)-chelating activity (%) of the hydrolyzed bovine plasma protein, were respectively established. We discovered the following three conditions for optimal hydrolysis of bovine plasma: pH of 7.82-8.32, temperature of 54.1 °C, and time of 338.4-398.4 min. We consequently succeeded in hydrolyzing bovine plasma protein under these conditions and confirmed the various desirable properties of optimal hydrolysis. Copyright © 2015 Elsevier Ltd.

    Full Text Available In the fields of Medicine and bovine production, there is a wide variety of diseases affecting reproduction, in relation to the number of live births, the interval between births and open days, among others. Some of these diseases produce abortions and embryonic death, which explain the alteration of reproductive parameters. Many of these diseases have an infectious origin, such as parasites, bacteria, viruses and fungi, which are transmitted among animals. Besides, some of them have zoonotic features that generate problems to human health. Among these agents, the Neospora caninum, protozoan stands out. Its life cycle is fulfilled in several species of animals like the dog and the coyote. These two act as its definitive hosts and the cattle as its intermediary host. The Neospora caninum causes in the infected animals, reproductive disorders, clinical manifestations and decreased production which affects productivity of small, medium and large producers. Because of this, diagnostic techniques that allow understanding the epidemiological behavior of this disease have been developed. However in spite of being a major agent in the bovine reproductive health, few studies have been undertaken to determine the prevalence of this agent around the world. Therefore, the objective of this review was to collect updated information on the behavior of this parasite, targeting its epidemiology, its symptoms, its impact on production and the methods of its control and prevention.

    The bovine papillomavirus (BPV) is the etiological agent of bovine papillomatosis, which causes significant economic losses to livestock, characterized by the presence of papillomas that regress spontaneously or persist and progress to malignancy. Currently, there are 13 types of BPVs described in the literature as well as 32 putative new types. This study aimed to isolate viral particles of BPV from skin papillomas, using a novel viral isolation method. The virus types were previously identified with new primers designed. 77 cutaneous papilloma samples of 27 animals, Simmental breed, were surgically removed. The DNA was extracted and subjected to PCR using Delta-Epsilon and Xi primers. The bands were purified and sequenced. The sequences were analyzed using software and compared to the GenBank database, by BLAST tool. The viral typing showed a prevalence of BPV-2 in 81.81% of samples. It was also detected the presence of the putative new virus type BR/UEL2 in one sample. Virus isolation was performed by ultracentrifugation in a single density of cesium chloride. The method of virus isolation is less laborious than those previously described, allowing the isolation of complete virus particles of BPV-2. Copyright © 2014 Elsevier B.V. All rights reserved.

  4. Regulation of DNA synthesis and the cell cycle in human prostate cancer cells and lymphocytes by ovine uterine serpin

    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.

  5. Uterine and eggshell structure and histochemistry in a lizard with prolonged uterine egg retention (Lacertilia, Scincidae, Saiphos).

    The eggshell of lizards is a complex structure composed of organic and inorganic molecules secreted by the oviduct, which protects the embryo by providing a barrier to the external environment and also allows the exchange of respiratory gases and water for life support. Calcium deposited on the surface of the eggshell provides an important nutrient source for the embryo. Variation in physical conditions encountered by eggs results in a tradeoff among these functions and influences eggshell structure. Evolution of prolonged uterine egg retention results in a significant change in the incubation environment, notably reduction in efficiency of gas exchange, and selection should favor a concomitant reduction in eggshell thickness. This model is supported by studies that demonstrate an inverse correlation between eggshell thickness and length of uterine egg retention. One mechanism leading to thinning of the eggshell is reduction in size of uterine shell glands. Saiphos equalis is an Australian scincid lizard with an unusual pattern of geographic variation in reproductive mode. All populations retain eggs in the uterus beyond the embryonic stage at oviposition typical for lizards, and some are viviparous. We compared structure and histochemistry of the uterus and eggshell of two populations of S. equalis, prolonged egg retention, and viviparous to test the hypotheses: 1) eggshell thickness is inversely correlated with length of egg retention and 2) eggshell thickness is positively correlated with size of shell glands. We found support for the first hypothesis but also found that eggshells of both populations are surprisingly thick compared with other lizards. Our histochemical data support prior conclusions that uterine shell glands are the source of protein fiber matrix of the eggshell, but we did not find a correlation between size of shell glands and eggshell thickness. Eggshell thickness is likely determined by density of uterine shell glands in this species.

    To assess the feasibility of computed tomography (CT) based thermometry during interstitial laser heating in the bovine liver. Four freshly exercised cylindrical blocks of bovine tissue were heated using a continuous laser of Nd:YAG (wavelength: 1064 nm, active length: 30 mm, power: 10-30 W). All tissues were imaged at least once before and 7 times during laser heating using CT and temperatures were simultaneously measured with 5 calibrated thermal sensors. The dependency of the average CT numbers as a function of temperature was analysed with regression analysis and a CT thermal sensitivity was derived. During laser heating, the growing hypodense area was observed around the laser source and that area showed an increase as a function of time. The formation of hypodense area was caused by declining in CT numbers at increasing temperatures. The regression analysis showed an inverse linear dependency between temperature and average CT number with -0.65 {+-} 0.048 HU/ C (R{sup 2} = 0.75) for the range of 18-85 C in bovine liver. The non-invasive CT based thermometry during interstitial laser heating is feasible in the bovine liver. CT based thermometry could be further developed and may be of potential use during clinical LITT of the liver. (orig.)

    2012-12-01

    Three samples of 250ml at home temperature of 20°C were obtained from whole, low fat and fat free bovine UHT milk. They were analysed by measuring both impedance spectra and dc conductivity in order to establish the relationship between samples related to fat content. An impedance measuring system was developed, which is based on digital oscilloscope, a current source and a FPGA. Data was measured by the oscilloscope in the frequency 1 kHz to 100 kHz. It was showed that there is approximately 7.9% difference in the conductivity between whole and low fat milk whereas 15.9% between low fat and free fat one. The change of fatness in the milk can be significantly sensed by both impedance spectra measurements and dc conductivity. This result might be useful for detecting fat content of milk in a very simple way and also may help the development of sensors for measuring milk quality, as for example the detection of mastitis.

  11. Expression of Heparin-Binding EGF-Like Growth Factor (HB-EGF) in Bovine Endometrium: Effects of HB-EGF and Interferon-τ on Prostaglandin Production.

    2015-06-01

    Heparin-binding EGF-like growth factor (HB-EGF) regulates several cell functions by binding to its membrane receptor (ErbB1 and ErbB4). Experimental evidences suggest that HB-EGF, prostaglandins (PGs) and interferon-τ (IFN-τ) regulate uterine function for pregnancy establishment in ruminants. In this study, the mRNA expressions of HB-EGF, ErbB1 and ErbB4 in bovine endometrium and the effects of HB-EGF and IFN-τ on PGE2 and PGF2-α production by endometrial cells were investigated. RT-PCR analysis revealed that HB-EGF mRNA was greater at the mid-luteal stage than at the early and regressed luteal stages (p HB-EGF, ErbB1 and ErbB4 mRNA in epithelial cells (p HB-EGF did not affect PGF2-α or PGE2 production by bovine endometrial epithelial cells, but increased PGF2-α and PGE2 production by bovine endometrial stromal cells (p HB-EGF-stimulated PGF2-α (p  0.05) production by stromal cells. These results indicate that HB-EGF and its receptors expression changed in bovine endometrium throughout the oestrous cycle. IFN-τ increased their expression in cultured endometrial cells. HB-EGF and IFN-τ have the ability to regulate PGs production by stromal cells and therefore may play a role in the local regulation of uterine function at the time of implantation in cattle. © 2015 Blackwell Verlag GmbH.

    2015-01-01

    There is concern that morcellation of occult leiomyosarcomas during surgery to treat presumed myomas may substantially worsen patient outcome. We reviewed the existing medical literature to better understand whether such a risk was demonstrable and, if so, what the magnitude of that risk might be. We identified 4864 articles initially, of which 60 were evaluated in full. Seventeen were found to have outcomes information and are included in this review. Six studies addressed the question of whether morcellation of occult leiomyosarcomas resulted in inferior outcomes as compared with en bloc uterine and tumor removal. In these 6 studies, results suggested that en bloc removal may result in improved survival and less recurrence; however, the data are highly biased and of poor quality. There is no reliable evidence that morcellation, power or otherwise, substantially results in tumor upstaging. There is no evidence from these 17 studies that power morcellation differs in any way from other types of morcellation or even simple myomectomy insofar as patient outcome. Whether electromechanical morcellation poses a unique danger to the patient with occult leiomyosarcoma is an unanswered question and one clearly in need of more extensive investigation before conclusions are drawn and policies created.

    What is the effect of uterine peristalsis on fluid migration after mock embryo transfer? Uterine peristaltic wave frequency was positively correlated with the distance that fluid moved after it was deposited in the uterine cavity. Embryos have been found outside the uterine cavity after embryo transfer. It has been suggested that uterine contractions expelled these embryos. A prospective cohort study of a total of 112 infertile women was conducted between March 2013 and May 2013. Uterine peristaltic activity was assessed before and after a mock embryo transfer, in which 20 µl of ultrasound contrast agent was placed in the uterine lumen 3 days after ovulation in a natural cycle. The movement of this fluid was measured by ultrasound at 0, 15 and 30 min after placement. The uterine peristaltic wave frequency was significantly higher after than before mock transfer (3.06 ± 0.99 versus 2.24 ± 0.74, P uterine peristaltic wave frequencies before (r = 0.518, P uterine peristaltic wave frequency was significantly higher both before and after embryo transfer in cases where the fluid was extruded. Mock embryo transfer was performed in the luteal phase of a natural cycle instead of a controlled ovarian stimulation cycle. The endometrial environment and uterine peristalsis may be different in a stimulated cycle. Uterine peristalsis exerts control over embryo migration and could adversely affect the chances of pregnancy if the wave frequency is too high. It could be used as a predictor of uterine irritability before embryo transfer. The authors declare that they have not received any particular study funding and do not have competing interests in this study.

    To determine an alternative to the uterine vein, considering the utero-ovarian vein (UOV) for venous drainage in human uterine transplantation. A case series of 10 total laparoscopic hysterectomies was conducted for benign indications and a vascular study was performed ex vivo on the surgical specimen, demonstrating ipsilateral and contralateral flow between the uterine artery (UA) and UOV visualizing anastomoses between these vessels. The flow pattern was documented using heparinized saline and illustrated through fluoroscopy using Isovue-300 dye. Successful cannulation of UA was accomplished in all 10 cases. Ipsilateral flow between the UA and UOV was demonstrated in all except one case, and contralateral flow was observed. Due to the long interval between the time of specimen retrieval and vascular study, the time to cannulation limited the ability to demonstrate ipsilateral and contralateral flow in 2 cases. Uterine transplantation has become a viable option for women with absolute uterine factor infertility. However, this surgery requires extensive surgical dissection, and the surgical retrieval of the uterine vein proposes a challenge. We present a potential option for venous drainage in uterine transplant surgery, considering the UOV for venous drainage as an alternative to the uterine vein and a possibility for minimally invasive approach. © 2016 S.

    Full Text Available To investigate the IgG content and its variations in uterine fluid (UF during the estrous cycle of the cow and to compare them with those of the blood serum (S, six pairs of serum and UF samples for each phase of the cycle selected out of 240 bovine genital tracts and blood samples were collected from Urmia abattoir. The UF samples were collected by gentle scraping of the endometrium using a curette after uterine incision and their IgG content and those of the serum were measured by single radial immuno-diffusion (SRID assay. Serum IgG values (Mean ± SEM were generally higher than the UF values throughout the cycle except for di-estrus (S: 38.50 ± 0.90, UF: 51.60 ± 2.10 mg mL-1, in which the highest values were observed in UF samples. In met-estrus the difference was not significant (S: 34.80 ± 1.80mg mL-1, UF: 30.80 ± 5.20 mg mL-1, however, in estrus the mean UF IgG value (12.50 ± 1.10 mg mL-1 was lower than that of the serum (31.30 ± 1.20 mg mL-1. In pro-estrus, the lowest values (S: 27.80 ± 1.30 mg mL-1, UF: 9.10 ± 1.50 mg mL-1 were obtained. The results showed a lower IgG values in the bovine UF than those of the serum in the follicular phase of the cycle, while in di-estrus the UF IgG content was the highest, suggesting some IgG production in the uterus at this phase.

    2010-01-01

    Full Text Available Bovine Respiratory Syndrome (BRS is a multifactorial disease caused by the interaction of infective agents, the environment and the individual immunological response of animals in the herd. Despite five decades of research on BRS, no clear understanding of how environmental factors influence pathogenic outcomes of the disease has been defined. As such, the development of immunoprophylaxis and vaccine programmes to prevent outbreaks of BRS in cattle has not been successful. The current paper discusses vaccination programmes for all categories of cattle and presents a review of existing vaccines being used for immunoprophylaxis of respiratory syndrome in cattle and discusses the advantages and disadvantages of the currently used vaccines and vaccination programmes. Lastly, a discussion detailing the design of future perfect vaccines is presented.

    2014-10-01

    Full Text Available Mastitis is one of the most prevalent and costly diseases in the dairy industry with losses attributable to reduced milk production, discarded milk, early culling, veterinary services, and labor costs. Typically, mastitis is an inflammation of the mammary gland most often, but not limited to, bacterial infection, and is characterized by the movement of leukocytes and serum proteins from the blood to the site of infection. It contributes to compromised milk quality and the potential spread of antimicrobial resistance if antibiotic treatment is not astutely applied. Despite the implementation of management practises and genetic selection approaches, bovine mastitis control continues to be inadequate. However, some novel genetic strategies have recently been demonstrated to reduce mastitis incidence by taking advantage of a cow’s natural ability to make appropriate immune responses against invading pathogens. Specifically, dairy cattle with enhanced and balanced immune responses have a lower occurrence of disease, including mastitis, and they can be identified and selected for using the High Immune Response (HIR technology. Enhanced immune responsiveness is also associated with improved response to vaccination, increased milk and colostrum quality. Since immunity is an important fitness trait, beneficial associations with longevity and reproduction are also often noted. This review highlights the genetic regulation of the bovine immune system and its vital contributions to disease resistance. Genetic selection approaches currently used in the dairy industry to reduce the incidence of disease are reviewed, including the HIR technology, genomics to improve disease resistance or immune response, as well as the Immunity+TM sire line.

    Uterine arteriovenous malformation (AVM) can cause massive hemorrhage and is often treated with uterine artery embolization (UAE), which may lead to ovarian insufficiency. Thus, avoiding UAE should be considered, particularly in women undergoing fertility treatments. We present three women diagnosed with postmiscarriage AVM on color Doppler by transvaginal ultrasound imaging. They had no genital bleeding and a small mass, measuring 16-22 mm. If estradiol was >300 pg/mL when AVM was diagnosed, then a gonadotropin-releasing hormone agonist was administered. All three women underwent follow-up observation, revealing spontaneous mass disappearance. To avoid ovarian insufficiency risk with UAE, conservative management and close follow-up observation should be considered in patients with AVM without bleeding, particularly during the fertility treatment.

    2011-01-01

    SURGICAL FINDINGS: an adenocarcinoma of the uterine stump with abdominal metastases is described in a 12.5-year-old incompletely ovariohysterectomised domestic shorthair cat. At the time of presentation, the adenocarcinoma had metastasised to the right perirenal lymph node, the abdominal aorta and the right ureter, resulting in the formation of a large cystic structure. This had compressed and displaced surrounding structures, including the abdominal vena cava and the right kidney, and formed multiple adhesions to the body wall and adjacent abdominal structures. Metastatic extension to the aorta had resulted in its regression into a 2 mm diameter non-pulsatile vessel. only one case of uterine adenocarcinoma has previously been reported in an ovariohysterectomised cat. As such, this represents a very unusual and severe complication following an incomplete ovariohysterectomy. Invasion of the tumour tissue into surrounding structures created further complications.

    2014-10-01

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

    Full Text Available Cutaneous leiomyomas are rare benign tumors arising from smooth muscle cells. The combination of cutaneous leiomyomatosis, uterine leiomyomatosis and renal cell cancer is referred to as ‘‘multiple cutaneous and uterine leiomyomatosis syndrome (Reed’s Syndrome’’. A forty-five-year-old female patient was admitted to our clinic with multiple painful bumps on the body. Diabetes mellitus and hysterectomy operation due to leiomyoma were present in her past medical history. Dermatologic examination revealed multiple, painful, skin coloured-red papulonodules forming clusters on the bilateral lomber area and a few lesions on right arm and back. Histopathological examination of the biopsy diagnosed as leiomyoma. The patient was treated with gabapentin which she had relief from pain at the end of 1 month.

    2009-01-31

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

  5. Spontaneous Hemoperitoneum in Pregnancy from a Ruptured Superficial Uterine Vessel

    Cheng-Yu Wu

    2007-03-01

    Full Text Available A 31-year-old multipara woman pregnant at gestational age 32+ weeks with twins encountered hemoperitoneum resulting from superficial uterine vessel rupture during tocolytic course. The initial presentations were unspecific and sonographic examination was negative. Later the aggravated symptoms led to an impression of abruptio placentae and emergent cesarean section was performed. A superficial venous bleeder was located on the posterior uterine wall and the internal bleeding was up to 3 L. Maternal and fetal outcome were good. Hemoperitoneum during pregnancy is rare but life-threatening to both mother and fetus, and it mimics placenta abruption in many ways. However, by careful investigations with cardiotocogram and bedside echo, they are quite distinguishable. Aggressive fluid replacement and immediate surgical intervention after rapid diagnosis provides the best prognosis.

    Adenoid cystic carcinoma (ACC) of the uterine cervix is a rare primary neoplasm of the uterus that occurs in post-menopausal women; its radiological findings have not been described previously. We present the MR findings of a case of ACC. The mass exhibited homogeneous low-signal intensity on T1-weighted images. On T2-weighted images, the mass showed high-signal intensity with a lobulated contour and multiple septum-like internal architectures. It also contained spots of very high-signal intensity, which would represent the mucin in the glandular lumen. The multiple septum-like internal architectures probably represented interglandular fibrous stroma. These MRI findings may be helpful for future diagnoses of ACC of the uterine cervix. (orig.)

    Purpose: To evaluate the radiation dose to the skin, uterus, and ovaries during uterine artery embolization. Material and Methods: Guided uterine artery embolization for leiomyomata and two types of X-ray equipment with different dose levels were utilized during fluoroscopy in 20 women (ages ranging from 32 to 52 years, body weights from 55 to 68 kg). The first 13 women were treated using a non-pulsed system A, with 3.3 mm Al filtering and, for simplicity, a fixed peak voltage 80 kV. During treatment of the other 7 women, a pulsed system B with 5.4 mm Al filtering and an identical fixed voltage was used. The dose area product (DAP) was recorded. The vaginal dose of the first 13 patients and the peak skin dose of all patients were measured with thermoluminescent dosimeters (TLDs). TLDs were placed in the posterior vaginal fornix and on the skin at the beam entrance site. The uterine and ovarian doses were estimated based on the measured skin doses, normalized depth dose, and organ depth values. The effective dose (D eff ) was estimated based on the observed DAP values. The measured vaginal doses and the corresponding estimated uterine doses were compared statistically, as were the DAP values from systems A and B. Results: For system A, the mean fluoroscopic time was 20.9 min (range 12.7-31.1), and for system B 35.9 min (range 16.4-55.4). The mean numbers of angiographic exposures for systems A and B were 82 (range 30-164) and 37 (range 20-72), respectively. The mean peak skin dose for system A was 601.5 mGy (range 279-1030) and for system B 453 mGy (range 257-875). The mean DAP for system A was 88.6 Gy cm{sup 2} (range 41.4-161.0) and for system B 52.5 Gy cm{sup 2} (range 20.1-107.9). Statistical analysis showed a significant difference between the DAP values, the DAP for system B being the lower one. The mean estimated effective doses from systems A and B were 32 mSv (range 15.1-58.4) and 22 mSv (range 9-46), respectively. The mean estimated maximum uterine and

    Uterine arteriovenous malformations (AVMs) are rare entities that have been documented in a wide age range. Several treatment modalities have been highlighted in the literature. Uterine artery embolization appears to be effective therapy for select cases. Embolization provides an alternative to hysterectomy and the potential for future fertility. To our knowledge, only 1 other case report describes an AVM existing within a bicornuate uterus. A 31-year-old, married, Caucasian woman with a history of infertility presented with intermittent uterine hemorrhage resulting in symptomatic anemia. The patient was diagnosed with a uterine AVM existing within the left horn of a bicornuate uterus. The patient underwent uterine artery embolization, with resolution of the vascular mass and resumption of regular menstrual flow. AVM in a bicornuate uterus is rarely reported. Selective uterine artery embolization offers an effective modality of treatment.

    Full Text Available Context - Uterine scar defects or scar niche are relatively common after cesarean delivery. An association has been observed between the severity of scar defect, also known as isthmocele, some gynecologic symptoms, and the risk of uterine scar dehiscence at the next delivery. It has been suggested that surgical repair of scar defect could improve the gynecological symptoms, but it remains unclear whether such surgery mends the uterine scar itself. Case Report - We report the case of a woman with uterine scar defect in whom laparoscopic repair significantly improved the gynecological symptoms without affecting the uterine scar, evaluated by hysterosonography. Conclusion - This case highlights the significant dearth of knowledge surrounding the diagnosis, consequences, and benefits of surgical repair of uterine scar defect after cesarean.

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

    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.

    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 efficacy and side-effect profile of ulipristal acetate as compared with those of leuprolide acetate for the treatment of symptomatic uterine fibroids before surgery are unclear. In this double-blind noninferiority trial, we randomly assigned 307 patients with symptomatic fibroids and excessive uterine bleeding to receive 3 months of daily therapy with oral ulipristal acetate (at a dose of either 5 mg or 10 mg) or once-monthly intramuscular injections of leuprolide acetate (at a dose of 3.75 mg). The primary outcome was the proportion of patients with controlled bleeding at week 13, with a prespecified noninferiority margin of -20%. Uterine bleeding was controlled in 90% of patients receiving 5 mg of ulipristal acetate, in 98% of those receiving 10 mg of ulipristal acetate, and in 89% of those receiving leuprolide acetate, for differences (as compared with leuprolide acetate) of 1.2 percentage points (95% confidence interval [CI], -9.3 to 11.8) for 5 mg of ulipristal acetate and 8.8 percentage points (95% CI, 0.4 to 18.3) for 10 mg of ulipristal acetate. Median times to amenorrhea were 7 days for patients receiving 5 mg of ulipristal acetate, 5 days for those receiving 10 mg of ulipristal acetate, and 21 days for those receiving leuprolide acetate. Moderate-to-severe hot flashes were reported for 11% of patients receiving 5 mg of ulipristal acetate, for 10% of those receiving 10 mg of ulipristal acetate, and for 40% of those receiving leuprolide acetate (Pulipristal acetate vs. leuprolide acetate). Both the 5-mg and 10-mg daily doses of ulipristal acetate were noninferior to once-monthly leuprolide acetate in controlling uterine bleeding and were significantly less likely to cause hot flashes.

    To evaluate the Cesarean uterine scar by the grey-level histogram (GLH) in women with a previous Cesarean section, performed either during labor or before labor (elective Cesarean). A prospective study was conducted with 40 women between 11 and 14 weeks of gestation, who were allocated to three groups: 15 pregnant women with a previous elective Cesarean (group A); 9 with a previous Cesarean section performed during labor (group B); and 16 with a single previous vaginal delivery (group C). The pregnant women were examined by transvaginal ultrasound, to obtain an image corresponding to the 'shadow' formed by the uterine scar in groups A and B. In group C GLH was accomplished in the region of the uterine isthmus. After capture of the image, the region-of-interest (ROI) was delimited and the option 'histogram' was activated, to automatically obtain graphic representation. The mean, median and standard deviation (SD) were calculated. for each group under study Mean values of the control group histograms were used as the normality parameter for comparison with the other groups. To compare averages of the three groups, the ANOVA test was used. A (p) value of < 0.05 was considered statistically significant. GLH in group A varied from 7.0 to 40.5 (mean: 24.9 and DP: 11.2), in group B from 23,1 to 47.2 (mean: 34,. and DP: 9.6) and in group C from 21.6 to 58.8 (mean: 40.3 and DP: 11.3). There was a significant difference of GLH in the region of the uterine scar of previous Cesareans, when it was elective and when performed during labor, suggesting a larger tissue change in the elective Cesarean.

    Full Text Available Various studies show that more than 600,000 women in Nepal are suffering from prolapsed uterus and that 200,000 of those needed immediate surgery. Many of the women with prolapse could recall the exact moment they first felt the prolapse and found difficulty to share the problems due to fear of stigma. Stories ranged from seven days immediately after the first delivery to after the birth of the fifth or sixth child; during cooking rice to sneezing and long coughing; fetching water in a big bucket to working in the field. If detected at an early stage, uterine prolapse (UP can be controlled by pelvic exercises. For severe cases, the remedy is to insert a ring pessary to stop it from descending which has to be changed every four months. In extreme cases, uterine tissue protrudes from the vagina causing extreme discomfort. The only remedy is hysterectomy in which the uterus is surgically removed. The operation costs are about NRs 20,000. The Government of Nepal and other donor organizations have allocated funds to provide services to about 10,000 to 12,000 women suffering from uterine prolapse as humanitarian support each year and services are likely to be expanded in future. Women suffering from UP have not been able to get benefit from such assistance due to deep rooted socio-cultural perceptions and practices. The number of suffering women, on the other hand, would not decrease from existing curative management policy without hammering the root causes of UP. Moreover, a clear vision and strategy is needed to shift from humanitarian aid to a more sustainable public health intervention.Keywords: Camp Approach; Humanitarian Aid; Socio-cultural Practices; Sustainable Policy; Uterine Prolapse DOI: 10.3126/dsaj.v4i0.4511 Dhaulagiri Journal of Sociology and Anthropology Vol.4 2010 pp.21-40

    Using viral metagenomics we analyzed four bovine serum pools assembled from 715 calves in the United States. Two parvoviruses, bovine parvovirus 2 (BPV2) and a previously uncharacterized parvovirus designated as bosavirus (BosaV), were detected in 3 and 4 pools respectively and their complete coding sequences generated. Based on NS1 protein identity, bosavirus qualifies as a member of a new species in the copiparvovirus genus. Also detected were low number of reads matching ungulate tetraparvovirus 2, bovine hepacivirus, and several papillomaviruses. This study further characterizes the diversity of viruses in calf serum with the potential to infect fetuses and through fetal bovine serum contaminate cell cultures.

    Full Text Available Myoma is the most common benign neoplasm that can occur in the female reproductive system, most frequently seen in women in their 50s. Although the majority of myomas are asymptomatic, some patients have symptoms and/or signs of varying degrees. Typical myoma-related symptoms or signs include: (1 menstrual disturbances like menorrhagia, dysmenorrhea and intermenstrual bleeding, (2 pelvic pain unrelated to menstruation, (3 compression symptoms, similar to a sensation of bloatedness, urinary frequency and constipation, (4 subfertility status such as recurrent abortion, preterm labor, dystocia with an increased incidence of Cesarean section, and postpartum hemorrhage, and (5 cosmetic problems due to increased abdominal girth However, there are undoubtedly some clinical presentations secondary to uterine myomas are not so specific, such as: (1 uncommon compression-related symptoms, (2 cardiac symptom and atypical symptoms secondary to vascular involvement or dissemination, (3 abdominal symptoms mimicking pelvic carcinomatosis, (4 dyspnea, (5 pruritus, (6 hiccup or internal bleeding, and (7 vaginal protruding mass or uterine inversion. Familiarization with these symptoms and awareness of other unusual or atypical presentations of uterine myomas will remind clinical practitioners of their significance, and of the necessity of follow-up examinations and individualized management to fit the needs and childbirth desires of the patients.

    Uterine fibroids are the most common benign tumors in women of reproductive age. Evidence suggest that ovarian steroid hormones, in particular, progesterone play a major role in promoting leiomyoma development and growth. For the last years there was an extensive research on selective progesterone receptor modulators and their use in therapy. Ulipristal acetate (UPA) is one of these modulators. The aim of this paper is to evaluate efficacy and safety of oral ulipristal acetate for the treatment in women with symptomatic uterine fibroids. The study group comprised five patients with uterine fibroids. All patients received 5 mg of ulipristal acetate per day for three months. The total volume of fibroids decreased by 33-68%. In all patients during the administration of UPA significant reduction of menstrual bleeding was observed. Increase of endometrial thickness without clinical significance was observed in two patients. No significant side-effects were observed during the treatment period. 1) The volume offibroids decreased from 33 to 68%. 2) The UPA administration effectively controlled excessive bleeding. 3) Treatment with UPA may modify the scope of the surgery. 4) UPA is a well-tolerated drug.

    Objective Power spectrum (PS) of uterine electromyography (EMG) can identify true labor. EMG propagation velocity (PV) to diagnose labor has not been reported. The objective was to compare uterine EMG against current methods to predict preterm delivery. Study design EMG was recorded in 116 patients (preterm labor, n=20; preterm non-labor, n=68; term labor, n=22; term non-labor, n=6). Student’s t-test was used to compare EMG values for labor vs. non-labor (P<0.05 significant). Predictive values of EMG, Bishop-score, contractions on tocogram, and transvaginal cervical length were calculated using receiver-operator-characteristics analysis. Results PV was higher in preterm and term labor compared with non-labor (P<0.001). Combined PV and PS peak frequency predicted preterm delivery within 7 days with area-under-the-curve (AUC) = 0.96. Bishop score, contractions, and cervical length had AUC of 0.72, 0.67, and 0.54. Conclusions Uterine EMG PV and PS peak frequency more accurately identify true preterm labor than clinical methods.

    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.

    The uterus is the major female sex organ and is essential for pregnancy. The organ is located in the pelvic cavity. It is usually fist-sized with its volume changing from 75 to 200 cc depending on the menstrual cycle. There are various diseases associated with the uterus, including malignancy, uterine myoma, postpartum hemorrhage, and vascular malformation. The conventional surgical treatment for these diseases is hysterectomy. However, hysterectomy has some risk, and there may be complications associated with the surgery and anesthesia. In addition, hysterectomy results in loss of fertility and loss of female characteristics, both of which may lead to emotional problems. After uterine artery embolization (UAE) was performed for post-partum bleeding in 1979 and for uterine myoma in 1995, interventional treatment of UAE replaced the existing surgical treatment of hysterectomy. UAE is performed widely as a minimally invasive treatment modality that can preserve the uterus, make pregnancy and childbirth possible and resolve emotional problems. The interventional treatment has become increasingly popular to treat various female genital diseases.

  8. Fetal Arthrogryposis Secondary to a Giant Maternal Uterine Leiomyoma

    José María Vila-Vives

    2012-01-01

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

  9. Treatment of early uterine sarcomas: disentangling adjuvant modalities

    Directory of Open Access Journals (Sweden)

    Kouloulias Vassilios

    2009-04-01

    Full Text Available Abstract Uterine sarcomas are a rare group of neoplasms with aggressive clinical course and poor prognosis. They are classified into four main histological subtypes in order of decreasing incidence: carcinosarcomas, leiomyosarcomas, endometrial stromal sarcomas and "other" sarcomas. The pathological subtype demands a tailored approach. Surgical resection is regarded as the mainstay of treatment. Total abdominal hysterectomy and bilateral salpingo-oophorectomy represents the standard treatment of uterine sarcomas. Pelvic and para-aortic lymph node dissection in carcinosarcomas is recommended, given their high incidence of lymph node metastases, and may have a role in endometrial stromal sarcomas. Adjuvant radiation therapy has historically been of little survival value, but it appears to improve local control and may delay recurrence. Regarding adjuvant chemotherapy, there is little evidence in the literature supporting its use except for carcinosarcomas. However, more trials are needed to address these issues, especially, their sequential application. Patients with uterine sarcomas should be referred to large academic centers for participation in clinical trials.

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

    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.

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

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

    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.

    Uterine transplantation may be a possible treatment option in the future for absolute uterine infertility. We describe three important areas of research that we feel are important in order to move closer to a successful and, crucially, safe transplant in the human setting. With closer collaboration among the various international teams working on this project, the first human uterine transplant should be possible in the next few years.

    Destruction of the endometrium due to trauma to the basal layer of endometrium may cause intra uterine adhesions, known as Asherman's syndrome (AS). There are various types of imaging method for diagnosis of the intra uterine adhesion such as hysterosalpingography, sonohysterography, ultrasonography, and hysteroscopy which is considered as the gold standard approach. Hysterosalpingogram may suggest the presence of intrauterine adhesions, and may reveal the extent of the scar formation. Knowing different images in each technique is helpful in detection of intra uterine adhesion.

    Pseudoaneurysm of uterine artery during pregnancy is a very rare disease. It is mostly associated with uterine artery injury, usually occurring after proceeding conditions such as history of gynecologic operation and infection. However, the best treatment modality has not been established yet. Herein, we reported a case of spontaneous formation of uterine artery pseudoaneurysm during pregnancy treated by direct thrombin injection without any complication or recurrence.

  19. Storage and Release of Spermatozoa from the Pre-Uterine Tube Reservoir

    2013-01-01

    In mammals, after coitus a small number of spermatozoa enter the uterine tube and following attachment to uterine tube epithelium are arrested in a non-capacitated state until peri-ovulatory signalling induces their detachment. Whilst awaiting release low numbers of spermatozoa continually detach from the epithelium and the uterine tube reservoir risks depletion. There is evidence of attachment of spermatozoa to uterine epithelium in several species which might form a potential pre-uterine tube reservoir. In this study we demonstrate that: (1) dog spermatozoa attach to uterine epithelium and maintain flagellar activity, (2) in non-capacitating conditions spermatozoa progressively detach with a variety of motility characteristics, (3) attachment is not influenced by epithelial changes occurring around ovulation, (4) attachment to uterine epithelium slows capacitation, (5) capacitated spermatozoa have reduced ability to attach to uterine epithelium, (6) under capacitating conditions increased numbers of spermatozoa detach and exhibit transitional and hyperactive motility which differ to those seen in non-capacitating conditions, (7) detachment of spermatozoa and motility changes can be induced by post-ovulation but not pre-ovulation uterine tube flush fluid and by components of follicular fluid and solubilised zona pellucida, (8) prolonged culture does not change the nature of the progressive detachment seen in non-capacitating conditions nor the potential for increased detachment in capacitating conditions. We postulate that in some species binding of spermatozoa to uterine epithelium is an important component of the transport of spermatozoa. Before ovulation low numbers of spermatozoa continually detach, including those which are non-capacitated with fast forward progressive motility allowing the re-population of the uterine tube, whilst around the time of ovulation, signalling from as-yet unknown factors associated with follicular fluid, oocytes and uterine tube

    2016-09-01

    Brucellosis is a globally important zoonotic infectious disease caused by gram negative bacteria of the genus Brucella. While many species of Brucella exist, Brucella melitensis, Brucella abortus, and Brucella suis are the most common pathogens of humans and livestock. The virulence of Brucella is largely influenced by its ability to evade host factors, including phagocytic killing mechanisms, which are critical for the host response to infection. The aim of this study was to characterize the bovine neutrophil response to virulent Brucella spp. Here, we found that virulent strains of smooth B. abortus, B. melitensis, B. suis, and virulent, rough, strains of Brucella canis possess similar abilities to resist killing by resting, or IFN-γ-activated, bovine neutrophils. Bovine neutrophils responded to infection with a time-dependent oxidative burst that varied little between Brucella spp. Inhibition of TAK1, or SYK kinase blunted the oxidative burst of neutrophils in response to Brucella infection. Interestingly, Brucella spp. did not induce robust death of bovine neutrophils. These results indicate that bovine neutrophils respond similarly to virulent Brucella spp. In addition, virulent Brucella spp., including naturally rough strains of B. canis, have a conserved ability to resist killing by bovine neutrophils.

    A Great Dane bitch was treated for presumed primary uterine inertia with repeated doses of oxytocin and manually assisted whelping. She was diagnosed with uterine rupture and septic peritonitis the following day. The uterine rupture is hypothesized to have occurred as a result of the management strategy used to treat dystocia. The dog underwent ovariohysterectomy, and the septic peritonitis was managed with open peritoneal drainage. The dog recovered well and was discharged 5 days later. No previous reports of canine uterine rupture associated with manual intervention appear to have been published. This report highlights the potential dangers involved in such an approach.

    Uterine arteriovenous malformation (AVM) is considered a rare condition. Diagnosis is critical because patients are at risk of significant vaginal hemorrhage that has been traditionally managed with surgery. We report 2 cases of uterine AVM after gestational trophoblastic disease in young women who were treated with uterine artery embolization, allowing preservation of reproductive capability. Embolization addresses both the preservation of future reproductive function and the prevention of major surgery and anesthesia. Success rates have been quoted as > 90% with minimal complications after uterine artery embolization.

    Uterine arteriovenous malformation is abnormal and nonfunctional connections between the uterine arteries and veins. Patients typically present with vaginal bleeding which may be life-threatening. Treatment depends on the symptoms, age, desire for future fertility, localization and size of the lesion. Embolization of the uterine artery is the first choice in symptomatic AVM in patients in the reproductive age. We report a case of acquired AVM with an extensive lesion on ultrasound and MRI, which was successfully treated with uterine artery embolization for severe bleeding (UAE).

    The objective of this study was to evaluate the progression of the uterine microbiota from calving until establishment of metritis. Uterine swabs (n = 72) collected at 0, 2, and 6 ± 2 days postpartum (dpp) from 12 metritic and 12 healthy cows were used for metagenomic sequencing of the 16S rRNA gene on the Illumina MiSeq platform. A heat map showed that uterine microbiota was established at calving. The microbiota changed rapidly from 0 to 6 ± 2 dpp, with a decrease in the abundance of Proteobacteria and an increase in the abundance of Bacteroidetes and Fusobacteria, which were dominant in metritic cows. Uterine microbiota composition was shared; however, metritic and healthy cows could be discriminated using relative abundance of bacterial genera at 0, 2, and 6 ± 2 dpp. Bacteroides was the main genus associated with metritis because it was the only genus that showed significantly greater abundance in cows with metritis. As the abundance of Bacteroides organisms increased, the uterine discharge score, a measure of uterine health, worsened. Fusobacterium was also an important genus associated with metritis because Fusobacterium abundance increased as Bacteroides abundance increased and the uterine discharge score worsened as the abundance increased. The correlation with uterine discharge score and the correlation with Bacteroides or Fusobacterium showed that other bacteria, such as Helcoccocus, Filifactor, and Porphyromonas, were also associated with metritis. There were also bacteria associated with uterine health, such as "Candidatus Blochmannia," Escherichia, Sneathia, and Pedobacter. Copyright © 2015, American Society for Microbiology.

    Effects of the sublingual administration of four beta-adrenoceptor drugs on the uterine motility in 40 normal menstruating women were studied. The drugs and total doses tested were: orciprenaline (40 mg), Partusisten (10 mg), salbutamol (8 mg) and isoxsuprine (40 mg). The uterine and antidiuretic activities were studied before and after administration of each one. All those drugs employed reduced greatly the uterine contractions in all the patients. The cardiovascular side-effects were minimal and well tolerated. It suggested that the adrenergic system has an important role in the control of uterine motility during human menstruation.

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

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

    Uterine receptivity to embryo implantation depends on appropriate progesterone (P4) and estrogen stimulation. P4 rapidly stimulates production of the morphogen Indian hedgehog (IHH) in murine uterine epithelium as well as downstream molecules in the hedgehog pathway such as Patched homolog 1 (PTCH1) and nuclear receptor subfamily 2, group F, member 2 (NR2F2) in uterine stroma. Studies using IHH-null mice indicate that IHH is obligatory for the normal P4 response in the uterus. To determine whether IHH induction in uterine epithelium is mediated through P4 receptor (PR) in epithelium (E) and/or stroma (S), we produced tissue recombinants using uteri from neonatal PR knockout (ko) mice and wild-type (wt) mice containing PR in S and/or E or lacking PR altogether using a tissue recombinant methodology and assessed their response to P4. In tissue recombinants containing wt-S (wt-S + wt-E and wt-S + ko-E), P4 induced Ihh mRNA expression at 6 h that was 6-fold greater than in oil-treated controls (P < 0.05; n = 6) in both types of tissue recombinants despite the absence of epithelial PR in wt-S + ko-E grafts. Conversely, Ihh mRNA expression was unaffected by P4 in ko-S + ko-E and ko-S + wt-E grafts despite epithelial PR expression in the latter. Nr2f2 and Ptch1 mRNA expression was similar in that it was stimulated by P4 only in recombinants containing stromal PR. These results indicate that stromal PR is both necessary and sufficient for P4 stimulation of epithelial IHH as well as downstream events such as PTCH1 and NR2F2 increases in stroma. PMID:19372202

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

    Blockade of immunoinhibitory molecules, such as programmed death-1 (PD-1)/PD-ligand 1 (PD-L1), is a promising strategy for reinvigorating exhausted T cells and preventing disease progression in a variety of chronic infections. Application of this therapeutic strategy to cattle requires bovinized chimeric antibody targeting immunoinhibitory molecules. In this study, anti-bovine PD-1 rat-bovine chimeric monoclonal antibody 5D2 (Boch5D2) was constructed with mammalian expression systems, and its biochemical function and antiviral effect were characterized in vitro and in vivo using cattle infected with bovine leukemia virus (BLV). Purified Boch5D2 was capable of detecting bovine PD-1 molecules expressed on cell membranes in flow cytometric analysis. In particular, Biacore analysis determined that the binding affinity of Boch5D2 to bovine PD-1 protein was similar to that of the original anti-bovine PD-1 rat monoclonal antibody 5D2. Boch5D2 was also capable of blocking PD-1/PD-L1 binding at the same level as 5D2. The immunomodulatory and therapeutic effects of Boch5D2 were evaluated by in vivo administration of the antibody to a BLV-infected calf. Inoculated Boch5D2 was sustained in the serum for a longer period. Boch5D2 inoculation resulted in activation of the proliferation of BLV-specific CD4+ T cells and decrease in the proviral load of BLV in the peripheral blood. This study demonstrates that Boch5D2 retains an equivalent biochemical function to that of the original antibody 5D2 and is a candidate therapeutic agent for regulating antiviral immune response in vivo. Clinical efficacy of PD-1/PD-L1 blockade awaits further experimentation with a large number of animals.

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