    The effects of the thermally-induced cracking and subsequent relocation of UO2 fuel pellets on the thermal and mechanical behavior of light-water reactor fuel rods during irradiation are quantified in this report. Data from the Nuclear Regulatory Commission/Pacific Northwest Laboratory Halden experiments on instrumented fuel assemblies (IFA) IFA-431, IFA-432, and IFA-513 are analyzed. Beginning-of-life in-reactor measurements of fuel center temperatures, linear heat ratings, and cladding axial elongations are used in a new model to solve for the effective thermal conductivity and elastic moduli of the cracked fuel column. The primary assumptions of the new model are that (1) the cracked fuel is in a hydrostatic state of stress in the (r,theta) plane, and that (2) there is no axial slipping between fuel and cladding. Three basic parameters are used to describe the cracked fuel: (1) the crack pattern, (2) the crack roughness, and (3) the fuel surface (gap) roughness. Recommendations are made on refining the model

    1998-10-01

    Modern PWR cladding materials are being tested in two joint programme tests; the cladding corrosion test IFA-638 and in the creep test IFA-617. The materials for the two tests, have been provided by four organisations: ABB-Atom, ENUSA, Framatome and Mitsubishi Heavy Industries. This report gives an overview of the different materials being tested as fuelled test rods and unfuelled cladding coupons in IFA-638. For IFA-638, cladding has been used for fabrication of both fresh and pre-irradiated test rods. The coupon materials, all in the unirradiated condition, comprise a range of alloys of different chemical composition, heat treatment, pre-filming and /or pre-hydriding treatment. Four pre-irradiated cladding materials of the same type of those used in IFA-638, have also been used to prepare the four fuelled subsegments that are being studied in the creep rig IFA-617. All currently available information related to the IFA-638 and IFA-617 material characterisation and properties are summarised in this report. (author)

  6. Gas Flow Measurements On IFA-504 And IFA-6 10.1

    1997-12-01

    This report covers the recent axial gas flow measurements performed in the Halden reactor on IFA-504 and IFA-610.1. The measurements are performed during hot standby and at power. Gas flow measurements have been performed at regular intervals on the three rods with solid pellets in IFA-504, which has reached a burnup of about 68 MWd/kgUO 2 . The measurements show, as earlier, a decrease in the hydraulic diameters, where rod number 2 has a smaller hydraulic diameter than rod number 1 and 3. Rod 1, 2 and 3 have, at the end of -97, hydraulic diameters of 9, 2.5 and 9.5 jim respectively at full power (15 kW/m). IFA-610.1 was loaded into the core in July-97 with a pre-irradiated segment, and has as of December -97 a burnup of 54 MWd/kgUO 2 . The primary objective of this rig was to perform a 'lift off' experiment where internal pressurisation of the test rod should provoke cladding creep out which would also cause an increase in the flow area. The fuel rod was pressurised to 300 bar overpressure, by steps of 50 bar. The results show an increase in the pellet-clad hydraulic diameter of 4-5 mm that occurred upon pressurisation from 0 to 200 bar overpressure. There was no sign of any further increase in the hydraulic diameter after pressurisation to 300 bar for one week. The operation with 300 bar overpressure will be continued. (author)

  8. Post-irradiation examination of the vipac fuel assemblies IFA-104 and IFA-203, irradiated in the Halden boiling water reactor

    Two seven pin assemblies, IFA-104 and IFA-203, have been irradiated in the Halding Boiling Water Reactor. The Zircaloy clad pins contained vibrationally compacted, sharp edged UO 2 particles with smear densities of 84-88% theoretical density and a fuel stack length of about 1520 mm. The IFA-104 pins operated satisfactorily during approximately 240 effective full power days at an average linear heat rating of about 340 W/cm, and a peak rating of about 480 W/cm. Ingress of water via a pressure transducer into one of the IFA-203 pins necessitated the premature termination of the irradiation after approximately 30 effective full power days at an average rating of about 460 W/cm, and a peak rating of about 550 W/cm. One IFA-104 pin and two IFA-203 pins failed early. The primary cause of these failures has been sought in the oxidation reaction of the tantalum tube which protected the W/Re thermocouples with the surrounding UO 2 or with moisture in the fuel at temperatures in excess of approximately 1700degC. The fuel centre temperature and the internal gas pressure measurements during the beginning of lifetime and the results of the post-irradiation chemical and microscopic analysis on fuel pin cross-sections have been correlated with corresponding data calculated on a Gapcon-Thermal computer programme written for pellet fuel pins. Fairly good agreement could be achieved between the measured data on the vipac pins and the calculated data of a pellet pin. During the corrosion of the Zircaloy-2 cladding of the IFA-104 pins which were autoclaved in 400degC steam prior to the irradiation, relatively large amounts of H 2 entered the cladding from the D 2 O coolant side. With 0.66 mole% H 2 O in the D 2 O the calculated hydrogen uptake preference ratio was 33

    1997-01-01

    Description: After twelve years irradiation in the Halden Boiling Water Reactor two fuel rods (Rod 807 and Rod 808) were re-instrumented with fuel centre thermocouples and reloaded into the reactor in order to investigate the fuel thermal behaviour at high burnup. The fuel rods were pre-irradiated with four other rods in the upper cluster of IFA-409 (IFA=Instrumented Fuel Assembly) from May 1973 to June 1985. After base irradiation the four neighbouring rods were re-instrumented with pressure transducers and ramp tested in IFA-535.5 and IFA-535.6 providing useful data about fission gas release (FGR) presented in the Fuel Performance Database as well (Ref. 1). The two rods re-instrumented with fuel centre thermocouples have been irradiated as IFA-533.2 from April 1992. As the irradiation history of IFA-533.2 in the first months was very similar to the history of the ramp tests, the fuel temperature and FGR data measured in the different IFAs can complement each other, although the fuel-cladding gap sizes were slightly different and due to re-instrumentation the internal gas conditions were also dissimilar

    In order to inform large scale supplementation programme design, we review and summarize the barriers and enablers for improved coverage and utilization of iron and folic acid (IFA) supplements by pregnant women in 7 countries in Africa and Asia. Mixed methods were used to analyse IFA supplementation programmes in Afghanistan, Bangladesh, Indonesia, Ethiopia, Kenya, Nigeria, and Senegal based on formative research conducted in 2012-2013. Qualitative data from focus-group discussions and interviews with women and service providers were used for content analysis to elicit common themes on barriers and enablers at internal, external, and relational levels. Anaemia symptoms in pregnancy are well known among women and health care providers in all countries, yet many women do not feel personally at risk. Broad awareness and increased coverage of facility-based antenatal care (ANC) make it an efficient delivery channel for IFA; however, first trimester access to IFA is hindered by beliefs about when to first attend ANC and preferences for disclosing pregnancy status. Variable access and poor quality ANC services, including insufficient IFA supplies and inadequate counselling to encourage consumption, are barriers to both coverage and adherence. Community-based delivery of IFA and referral to ANC provides earlier and more frequent access and opportunities for follow-up. Improving ANC access and quality is needed to facilitate IFA supplementation during pregnancy. Community-based delivery and counselling can address problems of timely and continuous access to supplements. Renewed investment in training for service providers and effective behaviour change designs are urgently needed to achieve the desired impact. © 2018 John Wiley & Sons Ltd.

    The NRC/PNL fuel assembly IFA-432 began irradiation in December 1975 and as of January 1980 had reached an assembly average burnup of 2120 GJ/kgU (24.5 GWd/MTM). The rods in this assembly are heavily instrumented and this has allowed a fairly thorough analysis of fuel behavior. The emphasis of the analysis has been to evaluate the observed changes in thermal/mechanical behavior. These changes are related to estimates of fuel density changes, fission gas release, and fuel cracking and relocation. The following conclusions have been reached concerning the irradiation of IFA-432. Based on analysis of steady-state and transient thermal data, the fuel in all rods is extensively cracked and relocated. Significant reductions in the effective fuel thermal conductivity have been deduced from the analysis of the transient thermal data

    This report presents beginning-of-life (BOL) data from the first four months of operation of the six-rod instrumented fuel assembly (IFA)-527 in the Halden Boiling Water Reactor (HBWR), Halden, Norway. This assembly is the last in a series of U.S. Nuclear Regulatory Commission (NRC)-sponsored tests to verify steady-state fuel performance computer codes. IFA-527 contains five identical rods with high-density stable fuel pellets and 0.23-mm diametral gaps and one rod with similar fuel pellets but with a 0.06-mm diametral gap. All six rods were xenon-filled to provide simulation of the effects of fission gas and to enhance the observable effects of fuel cracking and relocation on fuel temperatures. The assembly operated successfully from July 1, 1980, to August 15, 1980; and then the reactor was shut down until September 10, 1980. Sometime during the shutdown, four of the six rods suffered pressure boundary failure. The decision was made to restart the reactor to collect operating data with failed rods. This report presents both pre- and postfailure data for IFA-527.

    Few studies have evaluated the effectiveness of the Gow-Gates and Vazirani-Akinosi techniques in patients presenting with symptomatic irreversible pulpitis. Therefore, the purpose of this prospective, randomized study was to evaluate the anesthetic efficacy of the Gow-Gates and Vazirani-Akinosi techniques using 3.6 mL 2% lidocaine with 1:100,000 epinephrine in mandibular posterior teeth in patients presenting with symptomatic irreversible pulpitis. One hundred twenty-five emergency patients diagnosed with symptomatic irreversible pulpitis randomly received either a Gow-Gates or Vazirani-Akinosi injection using 3.6 mL 2% lidocaine with 1:100,000 epinephrine to block the inferior alveolar nerve before endodontic access. Subjective lip numbness was recorded. Pulpal anesthetic success of the injection was defined as no pain or mild pain upon endodontic access and instrumentation as measured on a visual analog scale. Subjective lip numbness was obtained 92% of the time with the Gow-Gates technique and 63% of the time with the Vazirani-Akinosi technique. The difference was statistically significant (P = .0001). For the patients achieving lip numbness, successful pulpal anesthesia was obtained 35% of the time with the Gow-Gates technique and 16% of the time with the Vazirani-Akinosi technique. The difference was statistically significant (P = .0381). We concluded that for patients who achieved lip numbness neither the Gow-Gates technique nor the Vazirani-Akinosi technique provided adequate pulpal anesthesia for mandibular posterior teeth in patients presenting with symptomatic irreversible pulpitis. Both injections would require supplemental anesthesia. Copyright © 2015 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

    This report includes results of the examination of the in-pile pressure data from instrumented test assemblies IFA-431 and 432. The pressure data have been used to estimate the fission gas release fraction as a function of fuel burnup. Included are comparisons of the estimated release functions and those predicted by three fission gas release models using the experimental temperature histories of the fuel rods. These comparisons show that fuel temperature is the primary factor in determining fission gas release and that burnup-enhanced fission gas release is not important in UO 2 fuels irradiated to 1700 GJ/kgU

    Objective: To evaluate the efficacy and safety of the interventional radiological techniques for management of symptomatic portal vein (PV) occlusion. Methods: Nine patients with PV trunk occlusion were treated using interventional procedures. Four patients presented with abdominal pain, distention, and malabsorption; five presented with portal hypertension and repeated bleeding from esophagogastric varices. The etiologic factors were identified in all 9 patients, including post-transplantation of the liver in 2, hepatocellular carcinoma (HCC) associated with PV tumor thrombus in 3, post abdominal operative state in 1, and PV thrombosis in 3 cases. The portal access was established via a percutaneous transhepatic route in 4, and via a transjugular intrahepatic portosystemic shunt ( TIPS) approach in 5 patients. The interventional procedures included stent placement in 4, balloon angioplasty in 6, and catheter directed pharmacologic and mechanical thrombolysis in 7 patients. Results: The technical success was achieved in all cases. No complications related to the procedure occurred. Portal flow was reestablished in all patients after the procedures. Clinical improvement was seen in 3 patients with symptomatic PV thrombosis, characterized by progressive reduction of abdominal pain, distention, and diarrhea. Follow-up time ranged from 4 to 36 months. One patient with HCC died of multiple organs metastases at 11 months after the treatment . One patient died of intraabdominal sepsis and multiple organs failure 12 days after the procedure even though the antegrade flow was re-established in the main trunk of the PV. Patency of the PV trunk was confirmed by follow-up color Doppler ultrasound scan in the rest 7 patients, without recurrence of variceal bleeding or PV thrombus. Conclusions: Interventional minimally invasive procedures, including balloon angioplasty, stent placement, catheter directed local pharmacologic and mechanical thrombolysis, are safe and effective in

    Results are presented for the post irradiation examination performed on IFA-431, which was a 6-rod test fuel assembly irradiated in Halden Reactor, Norway, under sponsorship of the Nuclear Regulatory Commission. The irradiation conditions included: peak powers of 33 kW/m; coolant pressure and temperature of 3.3 MPa and 240 0 C, respectively; and peak burnup of 4300 MWd/MTM. IFA-431 included instrumented rods of basic boiling water reactor design, with variations in fill gas composition, gap size, and UO 2 fuel type. The irradiation was designed to measure the effect of these variations upon fuel rod thermal and mechanical performance. The post irradiation examination assessed the permanent changes to the rods, including induced radioactivity, cladding deformation, fission gas release, and fuel densification

    This paper presents a new set of online catalogs of solar data products. The IfA Catalogs of Solar Data Products were developed to enhance the scientific output of coronal images acquired from ground and space, starting with the SoHO era. Image processing tools have played a significant role in the production of these catalogs [Morgan et al. 2006, 2008, Scholl and Habbal 2008]. Two catalogs are currently available at http://alshamess.ifa.hawaii.edu/ : 1) Catalog of daily coronal images: One coronal image per day from EIT, MLSO and LASCO/C2 and C3 have been processed using the Normalizing Radial-Graded-Filter (NRGF) image processing tool. These images are available individually or as composite images. 2) Catalog of LASCO data: The whole LASCO dataset has been re-processed using the same method. The user can search files by dates and instruments, and images can be retrieved as JPEG or FITS files. An option to make on-line GIF movies from selected images is also available. In addition, the LASCO data set can be searched from existing CME catalogs (CDAW and Cactus). By browsing one of the two CME catalogs, the user can refine the query and access LASCO data covering the time frame of a CME. The catalogs will be continually updated as more data become publicly available.

    The MOX fuel has been fabricated by attrition milling in cooperation with PSI. Two MOX fuels are being loaded in IFA-651 with the reference MOX fuel provided by BNFL. The MOX fuels have been irradiated in Halden reactor from June of 2000 until now and the in-pile test will be continued up to ∼ 50 MWd/kgHM for ∼ 5 calendar years. One of KAERI's MOX fuel is instrumented with ET while each of the other two rods has TF at the top end. All rods have PF at the bottom end. In addition, one KAERI's MOX fuel is instrumented with EF at the top of the fuel stack. MOX fuels have been successfully irradiated during eight cycles (2000. 6 ∼ 2005. 10), of which results have been reported already. The irradiation tests until the fourth cycle (IFA-651.1) can be summarized as follows: The densification of the MOX fuel rods shows 1∼2%, which means the densification has not been influenced by different fabrication method. On the other hand, the densification estimated by EF measurement indicates very negligible, which is much lower than values from PF. There is a fission gas release of 1 ∼ 3% during the third cycle. The fission gas release behavior at the MOX fuels is comparable to that of UO 2 fuel. The swelling estimated from PF measurement is ∼ 0.850%/10MWd/kgHM. At the end of four cycle irradiation, the IMF-2 rod was taken out for PIE. The second irradiation test of IFA-651.2 up to the eighth cycle from February 2004 to October 2005 reached the burnup of more than 40MWd/kgHM. The fuel centerline temperature was up to 1200 .deg. C. The higher linear heating rate of 250 ∼ 300 W/cm was observed due to the removing of IMF-2 rod. The fission gas release was 16% and 27% for MOX-ATT-ET and MOX-ATT-TF, respectively. The COSMOS code analyzed the in-pile data of IFA-651.1 and 2. The temperature and rod internal pressure was well simulated with the effect of thermal recovery accompanying with the significant fission gas release. Based on the irradiation test up to now, the

Darüşşifa is one of the names given to medical and educational establishments which give people health service depending on practice and observation and treated patients in Turkish and Islamic world. Turks started various reconstruction activities following their settlement in Anatolia. Within a short period, they built several types of artifacts such as; caravansaries, madrasahs, mosques, darüşşifas. In Seljukian and Ottoman darüşşifas, medical subjects were taught according to researches and scientific principals, and surgeons were educated at medical madrasahs as well. Medical health care service was provided in those places. In this study, of darüşşifas where music therapy was practised the ones surviving today and having importance have been analyzed so as to emphasize how curative power of art history and music was used by Turkish people centuries ago.

    To perform a list agreed by Argentinean experts and adapted to the local context containing potentially inappropriate (PI) medications in old people (OP) usingthe Delphi consensus technique optimized for this subject. A preliminary list of potentially inappropriate medications (PIM) was drawn up based on foreign PIM lists and a selective search in the scientific literature. The iterative Delphi process was used to submit the active pharmaceutical ingredients (APIs) of the preliminary PIM list to the panel of Argentinean experts. The analysis of theanswers to determine the arrival to the consensus was carried out applying three criteria specially defined for this purpose. After two Delphi rounds, it was not reached agreement about 12 APIs. The List of explicit criteria for PIAPIs for use in OP (IFAsPIAM List) was finally constituted by 128 APIs corresponding to 9 groups of the ATC classification system to which they were organized. In addition to each API, information justifying the unfavorable benefit/risk profile and therapeutic alternatives or recommendations/precautions was recorded. The group with the most PI APIs was N (NervousSystem) (60; 47%) followed by groups C (Cardiovascular) and M (Musculoskeletal). This study presents the first Latin American list of PIM in OP developed using an expert consensus technique. The IFAs PIAM List would contribute to the rational use of drugs in elderly population, constituting a valuable tool in Argentinean public health. Copyright © 2018. Published by Elsevier Inc.

    The indirect immunofluorescence assay (IFA) is considered the reference method for diagnosing Q fever, but serology is also performed by complement fixation assay (CFA) or enzyme-linked immunosorbent assay (ELISA). However, comparability between these assays is not clear, and therefore a quality assessment was performed. A total of 25 serum samples from negative controls, Q fever patients, and a serial diluted high-positive sample were analyzed in 10 Dutch laboratories. Six laboratories performed CFA, 5 performed IFA, and 5 performed ELISAs. Three international reference laboratories from Australia, France, and the USA also participated in this study. Qualitative values between laboratories using the same methods were within close range, and all 3 methods correctly identified acute Q fever patients. The IFA, ELISA, and CFA are all suitable serodiagnostic assays to diagnose acute Q fever, but the IFA remains an important tool in the follow-up of patients and in identifying patients at risk for developing chronic Q fever.

    The safety criteria for loss-of-coolant accidents were defined to ensure that the core would remain coolable. Since the time of the first LOCA experiments, which were largely conducted with fresh fuel, changes in fuel design, the introduction of new cladding materials and in particular the move to high burnup have generated a need to re-examine these criteria and to verify their continued validity. As part of international efforts to this end, the OECD Halden Reactor Project program implemented a LOCA test series. Based on recommendations of a group of experts from the US NRC, EPRI, EDF, IRSN, FRAMATOME-ANP and GNF, the primary objective of the experiments were defined as 1. Measure the extent of fuel (fragment) relocation into the ballooned region and evaluate its possible effect on cladding temperature and oxidation. 2. Investigate the extent (if any) of 'secondary transient hydriding' on the inner side of the cladding above and below the burst region. The fourth test of the series, IFA-650.4 conducted in April 2006, caused particular attention in the international nuclear community. The fuel used in the experiment had a high burnup, 92 MWd/kgU, and a low pre-test hydrogen content of about 50 ppm. The test aimed at and achieved a peak cladding temperature of 850 deg. C. The rod burst occurred at 790 deg. C. The burst caused a marked temperature increase at the lower end and a decrease at the upper end of the system, indicating that fuel relocation had occurred. Subsequent gamma scanning showed that approximately 19 cm of the fuel stack were missing from the upper part of the rod and that fuel had fallen to the bottom of the capsule. PIE at the IFE-Kjeller hot cells corroborated this evidence of substantial fuel relocation. The fact that fuel dispersal could occur upon ballooning and burst, i.e. at cladding temperatures as low as 800 deg. C and thus far lower than the temperature entailed by the current 1200 deg. C / 17% ECR limit, caused concern. The

    The objective of the dryout experiment with the instrumented fuel assembly IFA-613 is to provide information on the consequences induced on fuel by short terms dry outs having characteristics similar to those anticipated to occur from pump trips in a Boiling Water Reactor (BWR). For the third experiment it was planned to test one fresh and two pre-irradiated segments. Unfortunately one of the channels, Channel A developed a leakage and was not suitable for testing anymore. The rig was loaded with only two rods: one fresh PWR rod with a design similar to the fresh rod in IFA-613.1 and one pre-irradiated PWR segment (N1310 with a burn-up of 29 MWd/kgU). Both rods were equipped with a clad extensometer and two clad surface thermocouples (upper and lower position). The rig was loaded during the December 1997 shutdown and the dryout tests were performed on 16th January 1998. Both rods experienced temperature excursions with a target peak clad temperature (PCT) of 650 o C. According to the measured cladding temperatures, the time above the target temperature was about 4-5 s for both rods. The lower thermocouple did not indicate dryout at any occasion. The rig was unloaded immediately after the testing. (author)

    The release rate to birth rate ratio (R/B) results from the gas flow measurements performed during the joint programme irradiation of the IFA-633 UO 2 /MOX comparison test have been analysed using both classical and fractal methodologies. Possible calculational procedures for precursor enhancement factors and rod average diffusion coefficients were considered and suitable procedures were then implemented. The surface area to volume ratio (S/V) and recoil R/B values generated using the two methodologies have been compared to each other and to results obtained for other Halden Project gas flow rigs (IFAs 504, 558, 563, 569 and 655). The merits of the methodologies have then been discussed. It was found that the trends in the classical recoil R/B and in the fractal S/V for the shortest lived isotopes were in better agreement with the expected S/V behaviour than the trends in the classical S/V and in the fractal S/V for the longer lived isotopes. The beginning of life (BOL) S/V versus temperature behaviour for both IFA-633 and IFA-655 has been investigated and has been found to be more consistent with expectation when the fractal methodology is used. The peak fuel temperature versus rod average burnup behaviour of the IFA-633 fuel rods has been examined in order to investigate whether there is any correlation between the S/V results and the extent of periods during which the Halden (or Vitanza) threshold for significant fission gas release was exceeded. The behaviour was more consistent with the trends in the classical recoil R/B and fractal S/V for the shortest lived isotopes than with the trends in the classical S/V and the fractal S/V for the longer lived isotopes. The analysis of the through-life and BOL S/V and recoil R/B results generated using the classical and fractal methodologies has shown that the behaviour of the classical recoil R/B is difficult to explain. This is evidence that the classical recoil R/B results contain a diffusional release component

    Full Text Available An enzyme linked immunosorbent assay (ELISA was used to evaluate antibody positive titer in vaccinated and non-vaccinated cattle using schizont infected myeloid cells as an antigen. The result was compared with indirect fluorescent antibody level in the same animals. For this study 116 milking cows, 95 vaccinated and 21 non-vaccinated, were bleeded in order to prepare sera. They were tested with both ELISA and IFA tests. 94 sera had positive antibody titer and 22 sera were negative through ELISA test but, with IFA test, only 89 sera showed positive antibody titer and 27 were negative. Thereby, it was concluded that the sensitivity and specificity of ELISA test in comparison with IFA test was 95.5 % and 66.6 % respectively. This study generally indicated that ELISA could be an effective test for seroepidemiological investigations of bovine tropical theileriosis, and it is considered to be valid as an additional test to distinguish the vaccinated from the non vaccinated cattle in order to schedule vaccination programs.

    In this work, application of Idaho National Laboratory’s fuel performance code BISON to modelling of fuel rods from the Halden IFA-681 gadolinium fuel test is presented. First, an overview is given of BISON models, focusing on UO2/UO2-Gd2O3 fuel and Zircaloy cladding. Then, BISON analyses of selected fuel rods from the IFA-681 test are performed. For the first time in a BISON application to integral fuel rod simulations, the analysis is informed by detailed neutronics calculations in order to accurately capture the radial power profile throughout the fuel, which is strongly affected by the complex evolution of absorber Gd isotopes. In particular, radial power profiles calculated at IFE–Halden Reactor Project with the HELIOS code are used. The work has been carried out in the frame of the collaboration between Idaho National Laboratory and Halden Reactor Project. Some slide have been added as an Appendix to present the newly developed PolyPole-1 algorithm for modeling of intra-granular fission gas release.

    A Westinghouse Atom 8x8 fuel rod irradiated in the Ringhals 1 BWR for 12 years to a local burnup of about 67 MWd/kgU was refabricated, instrumented with centreline thermocouple and pressure transducer, and irradiated in IFA-597.2 for about 20 days and in IFA-597.3 for about four months. The rod was then sent to Kjeller for puncturing and then to the Studsvik hot cells for detailed post-irradiation examinations. The peak centreline, temperature was close to 1350 deg C. The total fission gas release (FGR) determined from the puncturing was approximately 20 %. Electron probe microanalysis on a fuel section from the central part of the rod showed that virtually 100 % Xe release had occurred in the central part of the pellet out to about half the pellet radius, and this thermal release from the central part of the fuel accounted for the measured total FGR. Optical and scanning electron microscopy of the fuel cross-section showed complete pellet-clad bonding as well as an extensive high burnup 'rim' structure extending at least 0,15 mm in from the fuel surface. The fuel microstructure was characterised at different radial positions in the pellet. This report describes modelling of the rod behaviour using the code SKIROD, in particular fuel temperature and fission gas release. The transient response of the fuel centre line temperature after a scram is also modelled using the code TOODEE2. The modelling results are compared to the experimental results

  11. From the teachers' eyes: An ethnographic-case study on developing models of Informal Formative Assessments (IFA) and understanding the challenges to effective implementation in science classrooms

    The emphasis on socio-cultural theories of learning has required the understanding of multi-dimensional, dynamic and social nature of acquiring the scientific knowledge and practices. Recent policy documents suggest a focus on formative and dynamic assessment practices that will help understand and improve the complex nature of scientific learning in classrooms. This study focuses on teachers' use of "Informal Formative Assessments (IFA)" aimed at improving students' learning and teachers' frequent recognition of students' learning process. The study was designed as an ethnographic case study of four middle school teachers and their students at a local charter school. The data of the study included (a) teachers' responses to history of teaching questionnaire (b) video and audio records of teachers' assessment practices during two different scientific projects (c) video and audio records of ethnographic interviews with teachers during their reflections on their practices, and (d) field notes taken by the researcher to understand the assessment culture of the school. The analytical tools from sociolinguistics (e.g., transcripts and event maps) were prepared and discourse analysis based in an ethnographic perspective was used to analyze the data. Moreover, Cultural-Historical Activity Theory (CHAT) was also introduced as an alternative data analysis framework for understanding the role of division of labor among the elements of the community on the challenges and the outcomes of IFA practices. The findings from the analysis of the classroom discourse showed three different types of IFA cycles: connected, non-connected, and repeating. The analysis of the teachers' reflections showed that the effectiveness of these cycles did not only depend on whether the cycles were connected, but also on other variables such as the phase of the lessons and student's identities and abilities.

    To verify the program FREG-3, we compared the calculations by FREG-3 with those by measurement in a HALDEN instrumented fuel assembly, IFA-224. FREG-3 generally gives higher pellet center temperatures than the measurement. The temperature distribution calculated by FREG-3 to estimate the stored energy in fuel rods results in safety side.

    This study compared microbial characteristics and oil sands process-affected water (OSPW) treatment performance of five types of microbial biomass (MBBR-biofilm, IFAS-biofilm, IFAS-floc, MBR-aerobic-floc, and MBR-anoxic-floc) cultivated from three types of bioreactors (MBBR, IFAS, and MBR) in batch experiments. Chemical oxygen demand (COD), ammonium, acid extractable fraction (AEF), and naphthenic acids (NAs) removals efficiencies were distinctly different between suspended and attached bacterial aggregates and between aerobic and anoxic suspended flocs. MBR-aerobic-floc and MBR-anoxic-floc demonstrated COD removal efficiencies higher than microbial aggregates obtained from MBBR and IFAS, MBBR and IFAS biofilm had higher AEF removal efficiencies than those obtained using flocs. MBBR-biofilm demonstrated the most efficient NAs removal from OSPW. NAs degradation efficiency was highly dependent on the carbon number and NA cyclization number according to UPLC/HRMS analysis. Mono- and di-oxidized NAs were the dominant oxy-NA species in OSPW samples. Microbial analysis with quantitative polymerase chain reaction (q-PCR) indicated that the bacterial 16S rRNA gene abundance was significantly higher in the batch bioreactors with suspended flocs than in those with biofilm, the NSR gene abundance in the MBR-anoxic bioreactor was significantly lower than that in aerobic batch bioreactors, and denitrifiers were more abundant in the suspended phase of the activated sludge flocs.

    Environmental water samples from the Lower Rhine area in Germany were investigated via immunofluorescence assays (IFAs), nested polymerase chain reaction (nested PCR) and loop-mediated isothermal amplification (LAMP) to detect the presence of Giardia spp. (n=185) and Cryptosporidium spp. (n=227). The samples were concentrated through filtration or flocculation, and oocysts were purified via centrifugation through a sucrose density gradient. For all samples, IFA was performed first, followed by DNA extraction for the nested PCR and LAMP assays. Giardia cysts were detected in 105 samples (56.8%) by IFA, 62 samples (33.5%) by nested PCR and 79 samples (42.7%) by LAMP. Cryptosporidium spp. were detected in 69 samples (30.4%) by IFA, 95 samples (41.9%) by nested PCR and 99 samples (43.6%) by LAMP. According to these results, the three detection methods are complementary for monitoring Giardia and Cryptosporidium in environmental waters. Copyright © 2016 Elsevier B.V. All rights reserved.

    This study tested the feasibility of plug-flow integrated fixed-film activated sludge (IFAS) reactor in applying sewage partial nitritation/anammox (PN/A) process. The IFAS reactor was fed with real pre-treated sewage (C/N ratio=1.3) and operated for 200days. High nitrogen removal efficiency of 82% was achieved with nitrogen removal rates of 0.097±0.019kgN/(m 3 ·d). Therefore, plug-flow IFAS reactor could be an alternative to applying sewage PN/A process. Besides, it was found that the stability of sewage PN/A process was significantly affected by residual ammonium. Nitrate accumulated in effluent and PN/A performance deteriorated when residual ammonium was below 1mg/L. On the contrary, long-term stable PN/A operation was achieved when residual ammonium was over 3mg/L. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available In the present study, the performance of Immunomagnetic Separation technique, coupled with Immunofluorescence (IMS-IFA, was compared with the FAUST et al. and Lutz parasitological techniques for the detection of Giardia lamblia cysts in human feces. One hundred and twenty-seven samples were evaluated by the three techniques at the same time showing a rate of cyst detection of 27.5% by IMS-IFA and 15.7% by both Faust et al. and Lutz techniques. Data analysis showed a higher sensitivity of IMS-IFA for the detection of G. lamblia cysts in comparison with the techniques of FAUST et al. and Lutz. The use of this methodology as a routine procedure enables the processing of many samples simultaneously, in order to increase recovery rate of G. lamblia cysts and reduce the time of sample storage.

    Seventeen pharmaceutically active compounds and 22 other trace organic pollutants were analysed regularly in the influent and permeate from a semi-real plant treating municipal wastewater. The plant was operated during 29 months with different configurations which basically differed in the type of biomass present in the system. These processes were the integrated fixed-film activated sludge membrane bioreactor (IFAS-MBR), which combined suspended and attached biomass, the moving bed membrane bioreactor (MBMBR) (only attached biomass) and the MBR (only suspended biomass). Moreover, removal rates were compared to those of the wastewater treatment plant (WWTP) operating nearby with conventional activated sludge treatment. Reverse osmosis (RO) was used after the pilot plant to improve removal rates. The highest elimination was found for the IFAS-MBR, especially for hormones (100% removal); this was attributed to the presence of biofilm, which may lead to different conditions (aerobic-anoxic-anaerobic) along its profile, which increases the degradation possibilities, and also to a higher sludge age of the biofilm, which allows complete acclimation to the contaminants. Operating conditions played an important role, high mixed liquor suspended solids (MLSS) and sludge retention time (SRT) being necessary to achieve these high removal rates. Although pharmaceuticals and linear alkylbenzene sulfonates showed high removal rates (65-100%), nonylphenols and phthalate could only be removed to 10-30%. RO significantly increased removal rates to 88% mean removal rate.

    1986-11-01

    The irradiation history and final postirradiation examination (PIE) results are presented for the Halden fuel assembly IFA-432. In particular, the three instrumented rods (Rods 2, 3, and 5) that continued to the highest burnup (46 MWd/kgM) are emphasized. The long survival rate of the fuel instrumentation allowed a continuous record to be kept of linear heat generation rate and fuel temperatures throughout the operating history of the asembly. Fission gas release was estimated based on a combination of gas retention and ceramographic data. The PIE data show that the postirradiation condition of the rods is qualitatively consistent with the power/temperature histories experienced. Fission gas release estimates are: Rod 2 (380 μm as-fabricated gap), 20-40%; Rod 5 (230 μm as-fabricated gap), 20-40%; and Rod 3 (76 μm as-fabricated gap), 0-20%

Peak burnups of 46 MWd/kgM were achieved. Interim destructive examination data were obtained at peak burnups of 24 and 34 MWd/kgM. This paper presents a synopsis of the irradiation histories and postirradiation examination data for the high burnup rods. The postirradiation condition of the rods correlates well with their individual design parameters and operating conditions

    There is a need to review the criteria for security relating to LOCA accidents , including the effect of different materials of pod, as well as conditions of high burned as fuel. In this work is modeled with code FRAPTRAN-1.4 the IFA-650.10 experiment executed in the experimental reactor HALDEN. It is an approximation to the thermo-hydraulic rod-refrigerant and the results are compared with experimental measurements. The thermal behavior shows good agreement with the experimental measures; mechanical parameters are observed light quality deviations in pod and very good quantitative agreement in the maximum elongation; the diameter calculated at the end of the simulation above - predicts the post-irradiation values and oxide presents a good deal.

    The objective of this study is to improve knowledge on the integrated fixed-film-activated sludge (IFAS) system designed for nitrogen removal. Biofilm growth and its contribution to nitrification were monitored under various operating conditions in a semi-industrial pilot-scale plant. Nitrification rates were observed in biofilms developed on free-floating media and in activated sludge operated under a low sludge retention time (4 days) and at an ammonia loading rate of 45-70 gNH4-N/kgMLVSS/d. Operational conditions, i.e. oxygen concentration, redox potential, suspended solids concentration, ammonium and nitrates, were monitored continuously in the reactors. High removal efficiencies were observed for carbon and ammonium at high-loading rate. The contribution of biofilm to nitrification was determined as 40-70% of total NOx-N production under the operating conditions tested. Optimal conditions to optimize process compacity were determined. The tested configuration responds especially well to winter and summer nitrification conditions. These results help provide a deeper understanding of how autotrophic biomass evolves through environmental and operational conditions in IFAS systems.

    Painful L5/S1 pseudoarthrosis has been previously managed with posterior excision and/or lumbar fusion. To our knowledge, the anterior approach for L5/S1 pseudoarthrectomy in the treatment of Bertolotti's syndrome has not been described. We present two patients with severe symptomatic L5/S1 pseudoarthroses that were successfully excised via an anterior retroperitoneal approach with 2 year clinical and radiological follow-up. The literature regarding surgical treatments for Bertolotti's syndrome is reviewed. The technique for an anterior retroperitoneal approach is described. This approach has been safe and effective in providing long term symptomatic relief to our two patients. Further studies comparing the outcomes of anterior versus posterior pseudoarthrectomy will guide the management of this condition. Copyright © 2013 Elsevier Ltd. All rights reserved.

    IFA-554/555 load-follow tests were performed in HALDEN reactor (HBWR) to study the MOX fuel behavior under the daily-load-follow operation condition in the framework of ATR-MOX fuel development in JAEA. IFA-554/555 rig had the instruments of rod inner pressure, fuel center temperature, fuel stack elongation, and cladding elongation. Although the daily-load-follow operation in nuclear power plant is one of the available options for economical improvement, the power change in a short period in this operation causes the change of thermal and mechanical irradiation conditions. In this report, FP gas release behavior of MOX fuel rod was evaluated under the daily-load-follow operation condition with the examination data from IFA-554/555 by using the computation code 'FASTGRASS'. From the computation results of FASTGRASS code which could compute the FP gas release behavior under the transient condition, it could be concluded that FP gas was released due to the relaxation of fuel pellet inner stress and pellet temperature increase, which were caused by the cyclic power change during the daily-load-follow operation. In addition, since the amount of released FP gas decreased during the steady operation after the daily-load-follow, it could be mentioned that the total of FP gas release at the end of life with the daily-load-follow is not so much different from that without the daily-load-follow.

    In the present study, a life cycle assessment (LCA) approach was used to analyse the environmental impacts associated with the construction and operational phases of an integrated fixed-film activated sludge (IFAS) reactor treating municipal wastewater. This study was conducted within the boundaries of a research project that aimed to investigate the implementation related challenges of a package type IFAS reactor from an environmental perspective. Along with the LCA results of the construction phase, a comparison of the LCA results of seven operational phases is also presented in this study. The results showed that among all the inputs, the use of stainless steel in the construction phase caused the highest impact on environment, followed by electricity consumption in raw materials production. The impact of the construction phase on toxicity impact indicators was found to be significant compared to all operational phases. Among the seven operational phases of this study, the dissolved oxygen phase III, having a concentration of ∼4.5 mg/L, showed the highest impact on abiotic depletion, acidification, global warming, ozone layer depletion, human toxicity, fresh water eco-toxicity, marine aquatic eco-toxicity, terrestrial eco-toxicity, and photochemical oxidation. However, better effluent quality in this phase reduced the eutrophication load on environment.

    Full Text Available Abstract Music therapy, one of the oldest treatment methods known, dates back to thousands of years. Turks’ using music therapy practices in hospitals -Ottoman and Seljuk hospitals- built with appropriate acoustic in the treatment of mental disorders, utilizing the books which included the researches done by scientists such as İbni Sina, Razî, Farabî, Hasan Şuurî and in Gevrekzade Hasan Efendi in music therapy and improving music therapy practices exemplarily in the period of Ottomans and Seljukians is assessed as the first serious music therapy practices. Darüşşifa is one of the names given to medical and educational establishments which give people health service depending on practice and observation and treated patients in Turkish and Islamic world. Turks started various reconstruction activities following their settlement in Anatolia. Within a short period, they built several types of artifacts such as; caravansaries, madrasahs, mosques, darüşşifas. In Seljukian and Ottoman darüşşifas, medical subjects were taught according to researches and scientific principals, and surgeons were educated at medical madrasahs as well. Medical health care service was provided in those places. In this study, of darüşşifas where music therapy was practised the ones surviving today and having importance have been analyzed so as to emphasize how curative power of art history and music was used by Turkish people centuries ago. From this point of view, Kayseri Gevher Nesibe Tıp Medresesi (Medical madrasah (1206, Divriği Ulu Camii ve Darüşşifası (Mosque and Hospital (1228, Amasya Darüşşifası (1309, Fatih Darüşşifası (1470 Edirne Sultan II.

    2006-03-01

    Plutonium-uranium mixed oxide (MOX) fuel rods of instrumental rig IFA-591 were ramped in HBWR to study the Advanced Thermal Reactor (ATR) MOX fuel behavior during transient operation and to determine a failure threshold of the MOX fuel rods. Eleven segments were base-irradiated in ATR 'FUGEN' up to 18.4 GWd/t. Zirconium liner claddings were adopted for four segments of them. As the results of non-destructive post irradiation examinations (PIEs) after the base-irradiation and before the ramp tests, no remarkable behavior affecting the integrity of fuel assembly and fuel rod was confirmed. All segments to be used for the ramp tests, which consisted of the multi-step ramp tests and the single-step ramp tests, had instrumentations for in-pile measurements of cladding elongation or plenum pressure, and heated up to the maximum linear power of 58.3-68.4 kW/m without failure. The major results of ramp tests are as follows: There is no difference in PCMI behaviors between two type rods of Zry-2 and Zirconium liner claddings from the in-pile measurements of cladding elongation and plenum pressure. The computations of cladding elongation and inner pressure gave slightly lower elongation and pressure than the in-pile measurements during the ramp-test. However, the cladding relaxation during the power hold was in good agreement, and the fission gas release behavior during cooling down could be evaluated by taking into account the relaxation of contact pressure between pellet and cladding. Although the final power during IFA-591 ramp tests reached the higher linear power than the failure threshold power of UO 2 fuel rods, no indication of fuel failure was observed during the ramp tests. The cladding relaxation due to the creep deformation of the MOX pellets at high temperature could be confirmed at the power steps during the multi-ramp test. The fission gas release due to the emancipation from PCMI stress was observed during the power decreasing. The burn-up dependence could be

  9. Results from the first cycle of the PWR crud deposition test (IFA-665.1)

    2004-03-01

    The main objective of IFA-665.1 is to deposit crud on fuel rods operating under PWR thermal-hydraulic and water chemistry conditions, and to measure the resulting power reduction due to incorporation of boron into the crud. The test has operated for 160 days at power. Water chemistry conditions were 3.15 ppm LiOH and 1400 ppm boron (pH 300 =7.0). The coolant inlet temperature was 290/294 C, with sub-cooled nucleate boiling along the upper half of the fuel bundle. This report presents the results from the first cycle of operation. Three methods have been used to attempt to accelerate crud formation: (i) injection of simulated crud particles (NiFe 2 O 4 ); (ii) pH transients (reduction of pH 300 from 7.0 to 6.0 for periods of 48 hours); and (iii) oxygen addition transients. While the pH transients resulted in movement of large amounts of corrosion products around the loop, no significant deposition onto the fuel surfaces was measured. Comparison of the heat fluxes in IFA-665 with those in previous tests in which crud deposition has occurred does not clearly identify reasons for the lack of crud formation, although it is noted that higher heat fluxes may be required. In addition, the relatively benign boiling conditions in the current test (small void fraction with no detached voidage) may partly explain the absence of crud formation. For the second cycle of the test, changes will be made to the water chemistry to attempt to increase the concentrations of dissolved and colloidal Fe and Ni in the test rig, such that a continuous (Fe + Ni) level of 100 ppb will be targeted, with short-term concentrations of colloids of up to 500 ppb.

    Conventional endovascular therapy of thoracoabdominal aortic aneurysm with involving visceral and renal arteries is limited by the absence of a landing zone for the aortic endograft. Solutions have been proposed to overcome the problem of no landing zone; however, most of them are not feasible in urgent and high-risk patients. We describe a case that was successfully treated by total endovascular technique with a two-by-two chimney-and-periscope approach in a patient with acute symptomatic type IV thoracoabdominal aortic aneurysm with supra-anastomotic aneurysm formation involving the renal and visceral arteries and a pseduaneurismatic sac localized in the left ileopsoas muscle.

    Uterine fibroids, the most common benign tumor in women of childbearing age, may cause symptoms including pelvic pain, menorrhagia, dysmenorrhea, pressure, urinary symptoms, and infertility. Various approaches are available to treat symptomatic uterine fibroids. Magnetic Resonance-guided Focused Ultrasound Surgery (MRgFUS) represents a recently introduced noninvasive safe and effective technique that can be performed without general anesthesia, in an outpatient setting. We review the principles of MRgFUS, describing patient selection criteria for the treatments performed at our center and we present a series of five selected patients with symptomatic uterine fibroids treated with this not yet widely known technique, showing its efficacy in symptom improvement and fibroid volume reduction.

  12. Inferred residual gaps for IFA-527 rods, compared to PIE measurements

    International Nuclear Information System (INIS)

    Lanning, D.D.

    1983-05-01

    The NRC-sponsored assembly IFA-527 contained six xenon-filled rods, each instrumented with fuel thermocouples at each end. Five of the six rods contained stable UO 2 fuel pellets with a fabricated diametral gap size of 230 microns. The rods were unique among instrumented test rods in that their lifetime peak powers were quite low (less than 20 kW/m). The assembly was removed at low exposure (about 2 MWd/kgM) due to pressure seal failures. The prefailure measured fuel temperatures in the five identical rods were quite similar, and indicated an effective fuel relocation of about 30 to 35 percent of the as-fabricated gap. Examination of rod cross sections in PIE, however, reveals virtually no reduction in the as-fabricated gap. In an attempt to reconcile these two observations, it is demonstrated that pellet eccentricity could account for the inferred effective relocation for these xenon-filled rods. That analysis is extended to an estimate of the proper effective relocation value for low-powered He-filled rods

    The Halden experiment IFA-560.2 was an experiment in which the corrosion behaviour of PWR fuel rodlets was investigated simultaneously under different load and cooling conditions: Permanent convective cooling at 50% power, permanent nucleate boiling at 100% power and periodic cycling between these two states. The objective was to study possible influences on the corrosion mechanism which might generically be related to the cycling operation. The oxide layer increments after 90 operations days and 60 day/night cycles were evaluated using the Siemens/KWU corrosion model regarding the special thermal hydraulic conditions of the experimental loop. The analysis proves that the layer thickness increases could be described purely following the changes in temperature caused by the power changes. No extra effect due to the frequent changes between the different cooling conditions could be observed. (orig.)

    Here, we present the clinical presentation and surgical outcomes of women with symptomatic urethral prolapse presenting to our institution over 20 years, and seek to provide treatment recommendations for management of symptomatic urethral prolapse and caruncle. A retrospective review of medical records from female patients who underwent surgery for symptomatic urethral prolapse from June 1995 to August 2015 was performed. Surgical technique consisted of a four-quadrant excisional approach for repair of urethral prolapse. A total of 26 patients were identified with a mean age of 38.8 years (range 3-81). The most common presentations were vaginal bleeding, hematuria, pain, and dysuria. All patients underwent surgical excision of urethral prolapse via a standard approach. Follow-up data was available in 24 patients. Six patients experienced temporary postoperative bleeding, and one patient required placement of a Foley catheter for tamponade. One patient experienced temporary postoperative urinary retention requiring Foley catheter placement. Three patients had visible recurrence of urethral prolapse, for which one later underwent re-excision. Surgical excision of urethral prolapse is a reasonable treatment option in patients who have tried conservative management without relief, as well as in those who present with severe symptoms. Possible complications following excision include postoperative bleeding and recurrence, and patients must be counseled accordingly. In this work, we propose a treatment algorithm for symptomatic urethral prolapse. © 2017 Wiley Periodicals, Inc.

    Seizures are believed to be common presenting symptoms in neonates and children with spontaneous intracerebral hemorrhage (ICH). However, few data are available on the epidemiology of acute symptomatic seizures or the risk for later epilepsy. To define the incidence of and explore risk factors for seizures and epilepsy in children with spontaneous ICH. Our a priori hypotheses were that younger age at presentation, cortical involvement of ICH, acute symptomatic seizures after presentation, ICH due to vascular malformation, and elevated intracranial pressure requiring urgent intervention would predict remote symptomatic seizures and epilepsy. Prospective cohort study conducted between March 1, 2007, and January 1, 2012. Three tertiary care pediatric hospitals. Seventy-three pediatric subjects with spontaneous ICH including 20 perinatal (≥37 weeks' gestation to 28 days) and 53 childhood subjects (>28 days to Acute symptomatic seizures (clinically evident and electrographic-only seizures within 7 days), remote symptomatic seizures, and epilepsy. Acute symptomatic seizures occurred in 35 subjects (48%). Acute symptomatic seizures as a presenting symptom of ICH occurred in 12 perinatal (60%) and 19 childhood (36%) subjects (P = .07). Acute symptomatic seizures after presentation occurred in 7 children. Electrographic-only seizures were present in 9 of 32 subjects (28%) with continuous electroencephalogram monitoring. One-year and 2-year remote symptomatic seizure-free survival rates were 82% (95% CI, 68-90) and 67% (95% CI, 46-82), respectively. One-year and 2-year epilepsy-free survival rates were 96% (95% CI, 83-99) and 87% (95% CI, 65-95), respectively. Elevated intracranial pressure requiring acute intervention was a risk factor for seizures after presentation (P = .01; Fisher exact test), remote symptomatic seizures, and epilepsy (P = .03, and P = .04, respectively; log-rank test). Presenting seizures are common in perinatal and childhood ICH. Continuous

    It is considered important to study the in-reactor behaviour of MOX fuel in order to enhance the database on such fuel. For this reason, IFA-597.4/.5/.6/.7 were included in the joint research programme of the Halden Project. The series of tests, containing two MIMAS-MOX fuel rods, both equipped with a fuel centre thermocouple and a pressure bellows transducer, has been irradiated in the Halden Reactor since July 1997 under HBWR conditions. The objectives of the test series were to study the thermal and fission gas release (FGR) behaviour of MOX fuel and to explore potential differences in behaviour between solid and hollow pellets. One of the rods had mainly solid pellets, while the other contained only hollow pellets. Both rods had an initial Pu-fissile enrichment of 6.07%. The cladding outside diameter was 9.50 mm, and the initial fuel-clad gap was 180 mum. In the course of the test, power upratings for FGR studies of the MOX fuel were planned at burnup intervals of about 10 MWd/kg MOX. The power uprating was successfully performed at approx10 MWd/kg MOX, where the estimated fuel peak temperature of the solid pellets exceeded the FGR threshold temperature for UO{sub 2} fuel, while that of the hollow pellets remained below the threshold. For the solid fuel, the temperature at onset of FGR was consistent with the empirical threshold temperature for UO{sub 2} fuel. For the hollow fuel, gas release was observed at temperatures below the threshold. FGRs at the end-of-life were approx17% for the solid pellet rod and approx14% for the hollow pellet rod, respectively. As a result of discussions in HPG meetings, IFA-597.7 was unloaded in January 2002. PIE was carried out to check in-pile pressure measurements and examine fuel structural characteristics. The discharge burn-up of the MOX fuel was 32 MWd/kg MOX as determined from in-pile power data. This report supersedes HWR-712 (June 2002) previously issued on in-pile data from IFA-597.4/5/6/7.

    Recently, surgical treatment of a symptomatic unicameral cyst of the proximal femur has been achieved with less invasive procedures than traditional open curettage with an autologous bone graft. In this article we introduce endoscopic surgery for a symptomatic unicameral cyst of the proximal femur. The presented technique, which includes minimally invasive endoscopic curettage of the cyst and injection of a bone substitute, not only minimizes muscle damage around the femur but also enables sufficient curettage of the fibrous membrane in the cyst wall and the bony septum through direct detailed visualization by an endoscope. Furthermore, sufficient initial strength after curettage can be obtained by injecting calcium phosphate cement as a bone substitute.

    We present a case of percutaneous treatment of symptomatic recurrent lumbar facet joint cyst resistant to all medical treatments including facet joint steroid injection. Percutaneous transfacet fixation was then performed at L4–L5 level with a cannulated screw using CT and fluoroscopy guidance. The procedure time was 30 min. Using the visual analog scale (VAS), pain decreased from 9.5, preoperatively, to 0 after the procedure. At 6-month follow-up, an asymptomatic cystic recurrence was observed, which further reduced at the 1-year follow-up. Pain remained stable (VAS at 0) during all follow-ups. CT- and fluoroscopy-guided percutaneous cyst rupture associated with facet screw fixation could be an alternative to surgery in patients suffering from a symptomatic recurrent lumbar facet joint cyst.

    Full Text Available The aim of the presented study was: a assessment of activity of microorganisms developed in form of activated sludge and biofilm, b indirect assessment of the role of analyzed biocoenoses in removal of organic compounds in hybrid reactor with moving bed. Oxygen uptake rate tests (OUR have been used, and obtained results were presented as volumetric activity (expressed in mg O2/L · h and mass activity (expressed as mg O2/g VTS · h. Tests were conducted for three different variants, in which, as the biomass: 1 biofilm was used, 2 activated sludge was used, 3 biofilm and activated sludge were used. The biomass was collected from aerobic reactor from a wastewater treatment plant working in IFAS-MBBR system. The highest volumetric activity was observed for variant with biofilm and activated sludge, and the lowest for variant with biofilm only. Nonetheless, the highest value of oxygen uptake rate related to total volatile solids was observed for variant with biofilm and the lowest for activated sludge. Obtained results suggest, that during this research, at the wastewater treatment plant, the main role in removal of organic pollutants played the biomass developed in form of activated sludge.

    The report presents the in-reactor data collected from the NRC/PNL Halden Assembly IFA-432 as a part of the program entitled ''Experimental Vertification of Steady State Fuel Codes,'' sponsored by the Fuel Behavior Research Branch of the USNRC. The purpose of this program is to reduce the uncertainties of calculating the thermal stored energy in an operating nuclear fuel rod. The report presents fuel centerline thermocouple readings, cladding elongation monitor readings, rod internal pressure readings, and neutron detector readings. The neutron detector readings were corrected to represent rod local powers at the thermocouple locations. These data are presented in the form of plots of the variables versus time during the portion of the irradiation period from December 1975 to January 1978. Also included are descriptions of the test rationale, assembly and rod designs, test facility, instrument array and calibration, and data processing methods. Topical reports discussing specific aspects and results of the data analysis are referenced. As of May 1978, the assembly burnup had reached its design goal of 20,000 MWd/MTM. However, it has been decided to leave the assembly in core to collect high burnup fission gas release data. The xenon-filled Rod 4 was replaced with the non-instrumented Rod 8 (Rod 1 design) after the first cycle. Six of the twelve original thermocouples, four of the six cladding elongation monitors, all SPND'S and all pressure transducers remain operable at this writing

    Symptomatic spondylolysis resulting from a stress fracture of the pars interarticularis is a cause of low back pain in the juvenile and adolescent patient. Treatment is conservative in the majority of cases. To analyze the outcome of patients with symptomatic isthmic spondylolysis treated nonoperatively with a custom fit thoracolumbar orthosis and activity cessation for 3 months followed by an organized physical therapy program. Retrospective case series. Four hundred thirty-six juvenile and adolescent patients with spondylolysis. Pain improvement, hamstring flexibility, range of motion, resolution of back spasms, and return to previous activities. Retrospective review of 436 juvenile and adolescent patients with symptomatic spondylolysis confirmed by single-photon emission computed tomography or computed tomography. Clinical outcomes were assessed through patient history and physical examination. Ninety-five percent of patients achieved excellent results according to a modified Odom's Criteria. The remaining 5% of patients achieved good results as they required occasional nonsteroidal anti-inflammatory drugs to relieve pain. Back spasms were resolved and hamstring tightness and range of motion returned to normal in all patients. All patients returned to their preinjury activity level. No patients went on to surgery. Symptomatic juvenile and adolescent patients with an isthmus spondylolysis may be effectively managed with a custom fit thoracolumbar orthosis brace and activity cessation for approximately 3 months followed by an organized physical therapy program.

    Symptomatic agoraphobics, recovered agoraphobics, and normal control subjects completed a series of sentence stems that had either ambiguous or unambiguous meanings, and had either a potentially threatening or a nonthreatening connotation. The written completions made by subjects to these stems were classified as indicating either a biased (i.e. threat-related) or unbiased interpretation of the meaning of the stem, and if a biased interpretation was made, whether the subject indicated efforts at adaptive coping with the perceived threat. Results indicated that symptomatic agoraphobics exhibited strong biases for interpreting information as threatening, relative to normal control subjects. Moreover, recovered agoraphobics resembled symptomatic agoraphobics more than normal control subjects, thus indicating that cognitive biases may persist following cessation of panic attacks and reductions in avoidance behavior. However, recovered agoraphobics also exhibited tendencies to cope adaptively with perceived threats whereas symptomatic agoraphobics did not.

    through several blow-downs and heat-ups and reached peak clad temperatures of more than 1000 C. In the second run, where the rod was sufficiently pre-pressurised, ballooning and burst was obtained. The first benchmark consisted of three rounds of code calculations related to IFA-650.3: 1. Pre-test calculations: Participants were provided with information regarding the setup of the Halden LOCA test facility, data from the commissioning runs, and information about the test pin and power conditions to be applied in the execution of the test. 2. Post-test calculations I: In addition to the information from the first round, participants were provided with the in-pile results from the test. 3. Post-test calculations II, unified thermal-hydraulic boundary conditions: Calculations were repeated using a cladding temperature distribution calculated with ATHLET-CD at GRS. Since the test, when executed, did not produce the expected ballooning and fuel relocation, it was decided to continue with a second benchmark using tests 650.4 and 650.5, this time as post-test calculations. The fourth test of the series, IFA-650.4 conducted in April 2006, caused particular attention in the international nuclear community. The fuel used in the experiment had a high burnup, 92 MWd/kgU, and a low pre-test hydrogen content of about 50 ppm. The cladding burst at about 790 deg. C caused a marked temperature increase at the lower end of the segment and a decrease at the upper end, indicating that fuel relocation had occurred. Subsequent gamma scanning showed that approximately 19 cm (40%) of the fuel stack were missing from the upper part of the rod. PIE at the IFE-Kjeller hot cells corroborated this evidence of substantial fuel relocation. This report presents the results of the codes which participated in the various benchmarks. The two main parts, on benchmark I and II, each start with a brief description of the most important experimental data. Then, the code calculation results follow

    Objective. To demonstrate the value of MR imaging in the diagnosis and differentiation of the various symptomatic complications of osteochondromas, providing pathological correlation with emphasis on the usefulness of MR imaging as a single imaging modality in these patients. Design. We retrospectively reviewed all MR examinations of clinically symptomatic osteochondromas (30 patients) performed at our institution between March 1990 and October 1997. Patients. Thirty patients had clinically symptomatic osteochondromas during the study period. Twenty patients were male and 10 were female. There were five cases of multiple osteochondromatosis. Pathological correlation was available in 24 patients. Results and conclusion. Symptomatic complications included fracture (7%), osseous deformity limiting range of motion (23%), vascular injury (7%), neurological compromise (10%), bursa formation (27%) and malignant transformation (27%). MR imaging was able to diagnose or suggest the etiology for the clinical symptomatology in all cases, demonstrating that it is an ideal imaging modality in the diagnostic evaluation of symptomatic complications of osteochondromas and often avoids the need for further imaging.

    Development of less invasive imaging studies, such as magnetic resonance angiography, has increased the chances that unruptured cerebral aneurysms are found. The rupture risk of 'symptomatic' aneurysms is higher than for 'asymptomatic' aneurysms; so 'symptomatic' aneurysms are more often surgically treated. Many reviews examine 'asymptomatic' unruptured cerebral aneurysms, but few evaluate 'symptomatic' aneurysms. The author has treated many patients with symptomatic unruptured cerebral aneurysms and found that improved cranial nerve signs can be expected if the surgical treatment is performed before the symptoms become irreversible; the critical period is approximately 3 months. It is important to suppress the pulsation of the aneurysms compressing the cranial nerves; both a clipping procedure and endovascular coiling are effective. Cranial nerve signs are more commonly the symptoms of unruptured cerebral aneurysms, but large to giant aneurysms can also be the causes of hemiparesis, hydrocephalus, epilepsy, or even cerebral infarction. This review summarizes the features and surgical outcome of symptomatic unruptured cerebral aneurysms. (author)

    Full Text Available After the report of a second case of canine visceral leishmaniasis (CVL in São Bento da Lagoa, Itaipuaçu, in the municipality of Maricá, Rio de Janeiro State, an epidemiological survey was carried out, through active search, totaling 145 dogs. Indirect immunofluorescence assay (IFA, enzyme-linked immunosorbent assay (ELISA, and rapid chromatographic immunoassay based on dual-path platform (DPP(r were used to perform the serological examinations. The parasitological diagnosis of cutaneous fragments was performed by parasitological culture, histopathology, and immunohistochemistry. In the serological assessment, 21 dogs were seropositive by IFA, 17 by ELISA, and 11 by DPP(r, with sensitivity of 66.7%, 66.7% and 50%, and specificity of 87.2%, 90.2% and 94%, respectively for each technique. The immunohistochemistry of bone marrow using the cell-block technique presented the best results, with six positive dogs found, three of which tested negative by the other parasitological techniques. Leishmania sp. was isolated by parasitological culture in three dogs. The detection of autochthonous Leishmania infantum in Itaipuaçu, and the high prevalence of seropositive dogs confirm the circulation of this parasite in the study area and alert for the risk of expansion in the State of Rio de Janeiro.

    Complications and failure of vertebroplasty, such as cement dislodgement, cement leakage, or spinal infection, usually result in spinal instability and neural element compression. Combined anterior and posterior approaches are the most common salvage procedure for symptomatic failed vertebroplasty. The purpose of this study is to evaluate the feasibility and efficacy of a single posterior approach technique for the treatment of patients with symptomatic failed vertebroplasty. Ten patients with symptomatic failed vertebroplasty underwent circumferential debridement and anterior reconstruction surgery through a single-stage posterior transpedicular approach (PTA) from January 2009 to December 2011 at our institution. The differences of visual analog scale (VAS), neurologic status, and vertebral body reconstruction before and after surgery were recorded. The clinical outcomes of patients were categorized as excellent, good, fair, or poor based on modified Brodsky's criteria. The symptomatic failed vertebroplasty occurred between the T11 and L3 vertebrae with one- or two-level involvement. The average VAS score was 8.3 (range, 7 to 9) before surgery, significantly decreased to 3.2 (range, 2 to 4) after surgery (p surgery was 17.3° (range, 4° to 35°) (p surgery was 1 mm (range, 0 to 2). The neurologic status of Frankel's scale significantly improved after surgery (p = 0.014) and at 1 year after surgery (p = 0.046). No one experienced severe complications such as deep wound infection or neurologic deterioration. All patients achieved good or excellent outcomes after surgery based on modified Brodsky's criteria (p surgery with circumferential debridement and anterior reconstruction technique provides good clinical outcomes and low complication rate, which can be considered as an alternative method to combined anterior and posterior approaches for patients with symptomatic failed vertebroplasty.

    Huanglongbing (HLB) is a highly destructive citrus disease which threatens citrus production worldwide and 'Candidatus Liberibacter asiaticus' (Las), a non-culturable phloem-limited bacterium, is an associated causal agent of the disease. To better understand the physiological and molecular processes involved in host responses to Las, 2-DE and mass spectrometry analyses, as well as ICP spectroscopy analysis were employed to elucidate the global protein expression profiles and nutrient concentrations in leaves of Las-infected grapefruit plants at pre-symptomatic or symptomatic stages for HLB. This study identified 123 protein spots out of 191 spots that showed significant changes in the leaves of grapefruit plants in response to Las infection and all identified spots matched to 69 unique proteins/peptides. A down-regulation of 56 proteins including those associated with photosynthesis, protein synthesis, and metabolism was correlated with significant reductions in the concentrations of Ca, Mg, Fe, Zn, Mn, and Cu in leaves of grapefruit plants in response to Las infection, particularly in symptomatic plants. Oxygen-evolving enhancer (OEE) proteins, a PSI 9 kDa protein, and a Btf3-like protein were among a small group of proteins that were down-regulated in both pre-symptomatic and symptomatic plants in response to Las infection. Furthermore, a Las-mediated up-regulation of 13 grapefruit proteins was detected, which included Cu/Zn superoxide dismutase, chitinases, lectin-related proteins, miraculin-like proteins, peroxiredoxins and a CAP 160 protein. Interestingly, a Las-mediated up-regulation of granule-bound starch synthase was correlated with an increase in the K concentrations of pre-symptomatic and symptomatic plants. This study constitutes the first attempt to characterize the interrelationships between protein expression and nutritional status of Las-infected pre-symptomatic or symptomatic grapefruit plants and sheds light on the physiological and molecular

    Full Text Available Myocardial bridging with systolic compression of the left anterior descending coronary artery (LAD may be associated with myocardial ischemia. In symptomatic myocardial bridging unresponsive to medical treatment, surgical unroofing of the left LAD can be performed. Little information is available about the long-term prognosis of patients with this coronary anomaly after the surgical unroofing, so we decided to evaluate the result of this operation. A total of 26 patients underwent surgical unroofing of myocardial bridging. Patients had a myocardial bridge of at least 3 cm in length in the middle of LAD and with more than 70% compression during systole. Unroofing was performed with cardiopulmonary bypass in 16 and with off pump technique in 10 patients. In 6 patients repeat angiographies for control of myotomy were done. In one of them a nonsignificant 20% narrowing was seen. Postoperative scintigraphic and angiographic studies demonstrated restoration of coronary flow and myocardial perfusion without residual myocardial bridges under beta-stimulation in 24 patients. Two patients had residual narrowing. With off pump technique, 1 patient had perforation of the right ventricle and 1 patient underwent reoperation because of incomplete unroofing during the first operation. None of the patients with cardiopulmonary bypass technique had residual chest pain or other complications. Surgical unroofing of myocardial bridging with the aid of cardiopulmonary bypass is a safe and easy procedure with low operative risk and with excellent functional results.

    The release of fission products from fuel pellets to the fuel-cladding gap is dependent on the fuel temperature, the power (fission rate) and the burnup (fuel structure). As part of the US Nuclear Regulatory Commission's Fuel Behavior Program, EG and G Idaho, Inc., is conducting fission product release studies in the Heavy Boiling Water Reactor in Halden, Norway. This paper presents a summary of the results up to December, 1982. The data cover fuel centerline temperatures ranging from 700 to 1500 0 C for average linear heat ratings of 16 to 35 kW/m. The measurements have been performed for the period between 4.2 and 14.8 GWd/t UO 2 of burnup of the Instrumented Fuel Assembly 430 (IFA-430). The measurement program has been directed toward quantifying the release of the short-lived radioactive noble gases and iodines

    Recently studies have indicated the existence of both posttraumatic stress disorder (PTSD) and acute stress disorder (ASD) subtypes but no studies have investigated their mutual association. Although ASD may not be a precursor of PTSD per se, there are potential benefits associated with early identification of victims at risk of developing PTSD subtypes. The present study investigates ASD and PTSD subtypes using latent class analysis (LCA) following bank robbery (N=371). Moreover, we assessed if highly symptomatic ASD and selected risk factors increased the probability of highly symptomatic PTSD. The results of LCA revealed a three class solution for ASD and a two class solution for PTSD. Negative cognitions about self (OR=1.08), neuroticism (OR=1.09) and membership of the 'High symptomatic ASD' class (OR=20.41) significantly increased the probability of 'symptomatic PTSD' class membership. Future studies are needed to investigate the existence of ASD and PTSD subtypes and their mutual relationship. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Previous studies have reported high levels of success with intraseptal injection for various dental procedures but provide limited information on the use of the injection during endodontic treatment. Therefore, the purpose of this prospective study was to determine the anesthetic efficacy of the supplemental intraseptal technique in mandibular posterior teeth diagnosed with symptomatic irreversible pulpitis when the conventional inferior alveolar nerve (IAN) block failed. One hundred patients with a diagnosis of symptomatic irreversible pulpitis in a mandibular posterior tooth were recruited. Following profound lip numbness after the administration of the conventional IAN block, endodontic treatment was initiated. Patients still experiencing moderate to severe pain during treatment were administered mesial and distal supplemental intraseptal injections using 0.7 mL 4% articaine with 1:000,000 epinephrine administered with a computer-controlled local anesthetic delivery unit. Success was defined as the ability to perform endodontic access and instrumentation with mild to no pain. Success with the IAN block was achieved in 25% of patients. Supplemental intraseptal injections provided success in 29% of patients. Supplemental intraseptal injections achieved profound pulpal anesthesia in 29% of patients when the IAN block failed. This low level of success would not provide predictable levels of anesthesia for patients requiring emergency endodontic treatment for symptomatic irreversible pulpitis in mandibular posterior teeth.

    The management of symptomatic pancreatic fistula after pancreaticoduodenectomy is complex and associated with increased morbidity and mortality. We here report continuous irrigation and drainage of the pancreatic remnant to be a feasible and safe alternative to total pancreatectomy. Between 2005 and 2011, patients were analyzed, in which pancreaticojejunal anastomosis was disconnected because of grade C fistula, and catheters for continuous irrigation and drainage were placed close to the pancreatic remnant. Clinical data were monitored and quality of life was evaluated. A total of 13 of 202 patients undergoing pancreaticoduodenectomy required reoperation due to symptomatic pancreatic fistula. Ninety-day mortality of these patients was 15.3%. Median length of stay on the intensive care unit and total length of stay was 18 d (range 3-45) and 46 d (range 33-96), respectively. Patients with early reoperation (<10 d) had significantly decreased length of stay on the intensive care unit and operation time (P < 0.05). Global health status after a median time of 22 mo (range 6-66) was nearly identical, when compared with that of a healthy control group. Mean follow-up was 44.4 mo (±27.2). Four patients (36.6 %) died during the follow-up period; two patients from tumor recurrence, one patient from pneumonia, and one patient for unknown reasons. Treatment of pancreatic fistula by continuous irrigation and drainage of the preserved pancreatic remnant is a simple and feasible alternative to total pancreatectomy. This technique maintains a sufficient endocrine function and is associated with low mortality and reasonable quality of life. Copyright © 2015 Elsevier Inc. All rights reserved.

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

    Purpose. Pelvic congestion syndrome is a common cause of chronic pelvic pain in women and its association with venous congestion has been described in the literature. We evaluated the potential benefits of lumboovarian vein embolization in the treatment of lower abdominal pain in patients presenting with pelvic varicosities. Methods. Nineteen patients were treated. There were 13 unilateral embolizations, 6 initial bilateral treatments and 5 treated recurrences (a total of 30 procedures). All embolizations were performed with either enbucrilate and/or macrocoils, and there was an average clinical and Doppler duplex follow-up of 15.4 months. Results. The initial technical success rate was 96.7%. There were no immediate or long-term complications. Variable symptomatic relief was observed in 73.7% of cases with complete responses in 57.9%. All 8 patients who had partial or no pain relief complained of dyspareunia. The direct relationship between varices and chronic pelvic pain was difficult to ascertain in a significant number of clinical failures. Conclusion. Transcatheter embolization of lumboovarian varices is a safe technique offering symptomatic relief of pelvic pain in the majority of cases. The presence of dyspareunia seemed to be a poor prognostic factor, indicating that other causes of pelvic pain may coexist with pelvic varicosities

    Idiopathic spinal cord herniation (ISCH) is an uncommon condition located predominantly in the thoracic spine and often associated with a remote history of a major traumatic injury. ISCH has an incompletely described presentation and unknown etiology. There is no consensus on the treatment algorithm and surgical technique, and there are few data on clinical outcomes. In this case series and technical report, we describe the atypical myelopathy presentation, remote history of traumatic injury, radiographic progression, treatment, and outcomes of 5 patients treated at Washington University for symptomatic ISCH. A video showing surgical repair is presented. In contrast to classic compressive myelopathy symptomatology, ISCH patients presented with an atypical myelopathy, characterized by asymmetric motor and sensory deficits and early-onset urinary incontinence. Clinical deterioration correlated with progressive spinal cord displacement and herniation observed on yearly spinal imaging in a patient imaged serially because of multiple sclerosis. Finally, compared with compressive myelopathy in the thoracic spine, surgical treatment of ISCH led to rapid improvement despite a long duration of symptoms. Symptomatic ISCH presents with atypical myelopathy and slow temporal progression and can be successfully managed with surgical repair.

    Previous small studies have shown either no difference or a lower risk of symptomatic gallstone disease in vegetarians than in non-vegetarians. This study examined the incidence of symptomatic gallstone disease in a cohort of British vegetarians and non-vegetarians, and investigated the associations between nutrient intake and risk of symptomatic gallstone disease. The data were analysed from 49 652 adults enroled in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Oxford study, one-third of whom were vegetarian. The linked databases of hospital records were used to identify incident cases. Risk by diet group was estimated using Cox proportional hazards models. Further analysis quantified risk by intakes of selected macronutrients. There were 1182 cases of symptomatic gallstone disease during 687 822 person-years of follow-up (mean=13.85 years). There was a large significant association between increasing body mass index (BMI) and risk of developing symptomatic gallstone disease (overall trend Pvegetarians had a moderately increased risk compared with non-vegetarians (HR: 1.22; 95% CI: 1.06-1.41; P=0.006). Although starch consumption was positively associated with gallstones risk (P=0.002 for trend), it did not explain the increased risk in vegetarians. There is a highly significant association of increased BMI with risk of symptomatic gallstone disease. After adjusting for BMI, there is a small but statistically significant positive association between vegetarian diet and symptomatic gallstone disease.

    Describe the clinical presentation, diagnostic evaluation, and successful treatment of a case of symptomatic unilateral lumbosacral junction pseudarticulation using a novel radiofrequency nerve ablation technique. A 56-year-old female patient who had suffered with low back and right upper buttock pain for 16 years experienced incomplete relief with L4/5 facet joint radiofrequency ablation. She was found to have an elongated right L5 transverse process that articulated with the sacral ala (Bertolotti's syndrome). Fluoroscopically guided local anesthetic/corticosteroid injection into the pseudarthrosis eliminated her residual right buttock pain for the duration of the local anesthetic only. Complete pain relief was achieved by injecting local anesthetic circumferentially around the posterior pseudarthrosis articular margin. Accordingly, bipolar radiofrequency strip thermal lesions were created at the same locations. Complete pain relief and full restoration of function was achieved for 16 months postprocedure. This case report describes a novel radiofrequency technique for treating symptomatic lumbosacral junction pseudarticulation that warrants further evaluation.

    Although stereotactic ablative body radiotherapy (SABR) is widely used therapeutic technique, predictive factors of radiation pneumonitis (RP) after SABR remain undefined. We aimed to investigate the predictive factors affecting RP in patients with primary or metastatic lung tumors who received SABR. From 2012 to 2015, we reviewed 59 patients with 72 primary or metastatic lung tumors treated with SABR, and performed analyses of clinical and dosimetric variables related to symptomatic RP. SABR was delivered as 45–60 Gy in 3–4 fractions, which were over 100 Gy in BED when the α/β value was assumed to be 10. Tumor volume and other various dose volume factors were analyzed using median value as a cutoff value. RP was graded per the Common Terminology Criteria for Adverse Events v4.03. At the median follow-up period of 11 months, symptomatic RP was observed in 13 lesions (12 patients, 18.1%), including grade 2 RP in 11 lesions and grade 3 in 2 lesions. Patients with planning target volume (PTV) of ≤14.35 mL had significantly lower rates of symptomatic RP when compared to others (8.6% vs. 27%; p = 0.048). Rates of symptomatic RP in patients with internal gross tumor volume (iGTV) >4.21 mL were higher than with ≤4.21 mL (29.7% vs. 6.1%; p = 0.017). The incidence of symptomatic RP following treatment with SABR was acceptable with grade 2 RP being observed in most patients. iGTV over 4.21 mL and PTV of over 14.35 mL were significant predictive factors related to symptomatic RP.

    Leiomyoma affects up to 50% of fertile women, leading to morbidity such as bleeding or pain. The effect of symptomatic leiomyoma on the productivity of employed women is understudied. The present study investigates productivity loss in a Swedish setting in women with symptomatic leiomyoma compared to healthy women. Women seeking care for leiomyoma and heavy menstrual bleeding (HMB) were recruited at nine Swedish sites. Healthy controls with self-perceived mild to normal menstruation were recruited at routine visits. Cases and controls were employed without option to work from home. After recruitment, all women reported the work productivity and activity impairment (WPAI) questionnaire, the pictorial blood assessment chart (PBAC) and pain on the visual analog scale (VAS). Women with symptomatic leiomyoma (n = 88) missed more working time during menses compared to asymptomatic controls (n = 34): 7.6 vs 0.2% p = 0.003. The proportion of impairment while working was also significantly higher in women with symptomatic leiomyoma (43.8 vs 12.1% p100). Symptomatic leiomyoma leads to loss of working hours as well as loss of productivity during working hours, and affects women in other daily activities. Increased awareness of the impact of leiomyomas on women's lives is needed, and timely and appropriate management of the symptomatic leiomyomas could improve work productivity and quality of life.

    The purpose of this study is to assess the MR findings of symptomatic osteochondromas. We evaluated 31 patients who between July, 1994 and May, 1997 underwent MR imaging for symptomatic osteochondroma. Fourteen were males and 17 were females, and their ages ranged from 8 to 49 (mean, 23) years. Using T1WI, T2WI and gadolinium-DTPA-enhanced T1WI, images were analysed according to signal intensity in the osseous component of the osteochondroma, thickness of the cartilage cap, and associated change in surrounding soft tissue. Clinical manifestation included a palpable mass or tendency to grow (n=22) and pain on movement (n=9). Complications were of three types : that which followed change in the osseous component of the tumor, associated change in surrounding soft tissue, and malignant transformation. In the osseous component, bone marrow edema or contusion was seen in 21 cases (67.7%), and in two (65%), fracture was observed. In surrounding soft tissue, muscle impingement was seen in 21 cases (67.7%), bursitis was in 7 cases (22.6 %), tenosynovitis in seven (22.6 %), and vascular compression in five (16.1 %). In three cases (9.7%), transformation to chondrosarcoma had occurred; two of these were derived from osteochondromatosis and one from a single osteochondroma. The thickness of the cartilage cap was as follow : 10 mm (n=3). In patients with symptomatic osteochondroma, MR imaging is useful for detecting both complications and malignant transformation.

    Gastroschisis is known to be associated with abnormal bowel rotation. Currently, the broadly accepted practice is not to perform Ladd\\'s procedure routinely at the time of closure of gastroschisis defects. However the incidence of symptomatic malrotation and volvulus post gastroschisis repair is unknown; this incidence is important in view of the current practice of bedside gastroschisis closure. This study examined the incidence of symptomatic malrotation and volvulus following gastroschisis repair.

    Objective: Stent placement for intracranial atherosclerotic stenosis has become an alternative treatment technique; however, stent placement for middle cerebral artery (MCA) stenosis remains a technical and clinical challenge. Our purpose was to assess the safety and feasibility of Wingspan stent for patients with symptomatic M1 stenosis, and its initial effect on prevention of ischemic events. Methods: Fifty-three cases with recurrent symptomatic MCA stenosis resistant to medical therapy treated by self-expanding stent were reviewed retrospectively (average 58 ± 18.5 years old, 19 women). All patients underwent angioplasty and stenting with the Gateway balloon–Wingspan stent system, and advised follow-up with DSA or TCD at 6th month. Results: Patients had an average stenosis ratio of 76.5 ± 15.4% prior to the treatment. Of the 53 patients, the technical success rate was 98.1% as a whole (52/53). The mean degree of stenosis reduced from (76.5 ± 15.4)% to (18.2 ± 11.3)%. Complications associated with the procedure include subarachnoid hemorrhage (1.89%) and occlusion (3.78%) occurred. During a follow-up of 6 months, there was no recurrence of transient ischemic attack or stroke in 52 cases with successful stenting. Cerebral hemodynamics of MCA using transcranial Doppler monitoring were at normal level (<120 cm/s) in 41 follow-up patients. The follow up angiography at 6 month post-procedure was conducted in 32 patients and showed good patency in stented vessels. Conclusions: Wingspan stent for symptomatic stenosis of middle cerebral artery is a safe and feasible procedure. It improves clinical outcome in the intermediate follow up, but its long-term effect remains to be further evaluated.

    The treatment of Tarlov cysts is challenging and difficult. The objective of our study was to describe the security and efficacy of the subcutaneous infusion port for drainage of symptomatic Tarlov cysts. The authors executed a retrospective review of data from 5 symptomatic Tarlov cysts patients who were treated using a subcutaneous infusion port from June 2014 to July 2017. Numerical Rating Scale scores and the Japanese Orthopedic Association scores of back pain were analyzed. Complications and adverse effects on postoperative days 1, 7, 14, and 28 were also analyzed. The mean follow-up was 12.6 months. Five adults (3 females and 2 males) who had been symptomatic received a subcutaneous infusion port. After treatment, all patients experienced pain relief and pain alleviation lasted from 1 day to 3 years without complications and adverse effects. A subcutaneous infusion port is a useful treatment option for symptomatic Tarlov cysts. When the patients' symptoms returned and the cysts repressurized, we quickly and simply drained the cysts by using the infusion port. Copyright © 2018 Elsevier Inc. All rights reserved.

    Apical periodontitis of endodontic origin may develop as a result of cooperative interactions among herpesviruses, specific pathogenic bacteria and tissue-destructive inflammatory mediators. This study sought to identify the presence of Epstein-Barr virus (EBV) and human cytomegalovirus (HCMV) transcripts in symptomatic and asymptomatic periapical lesions of individuals living in Iran. Fifty endodontic patients (28 with symptomatic periapical lesions and 22 with asymptomatic periapical lesions) were included in the study. In each study subject, a microbiological periapical sample was collected using a curette in conjunction with periapical surgery. A reverse transcription-polymerase chain reaction assay was used to identify transcripts of EBV and HCMV. Human cytomegalovirus transcript was detected in 15 of the 28 (53.6%) symptomatic and in six of the 22 (27.3%) asymptomatic periapical study lesions (significant difference between symptomatic and asymptomatic lesions; P = 0.03, chi-square test). Epstein-Barr virus transcript was identified in one symptomatic and in two asymptomatic periapical lesions. This study establishes that HCMV transcription is common in apical periodontitis and is most frequent in symptomatic lesions. The high frequency of active herpesvirus infections in severe apical periodontitis changes the pathogenic paradigm of the disease and may also have preventive and therapeutic implications.

    Full Text Available "nEndodontic treatment of immature permanent teeth accompanies with several issues. The primary goal when treating such teeth is to maintain pulp vitality so that root development can occur normally. Indications and requirements for vital pulp therapy include asymptomatic and reversible pulpitis. Also there are controversial opinions regarding the ultimate clinical treatment of the vital pulp therapy techniques. In this manuscript we report 3 cases of immature symptomatic permanent molars with irreversible pulpitis caused by caries exposure of the pulp that have been undergone vital pulp therapy successfully.

    The purpose of this study is to assess the MR findings of symptomatic osteochondromas. We evaluated 31 patients who between July, 1994 and May, 1997 underwent MR imaging for symptomatic osteochondroma. Fourteen were males and 17 were females, and their ages ranged from 8 to 49 (mean, 23) years. Using T1WI, T2WI and gadolinium-DTPA-enhanced T1WI, images were analysed according to signal intensity in the osseous component of the osteochondroma, thickness of the cartilage cap, and associated change in surrounding soft tissue. Clinical manifestation included a palpable mass or tendency to grow (n=22) and pain on movement (n=9). Complications were of three types : that which followed change in the osseous component of the tumor, associated change in surrounding soft tissue, and malignant transformation. In the osseous component, bone marrow edema or contusion was seen in 21 cases (67.7%), and in two (65%), fracture was observed. In surrounding soft tissue, muscle impingement was seen in 21 cases (67.7%), bursitis was in 7 cases (22.6 %), tenosynovitis in seven (22.6 %), and vascular compression in five (16.1 %). In three cases (9.7%), transformation to chondrosarcoma had occurred; two of these were derived from osteochondromatosis and one from a single osteochondroma. The thickness of the cartilage cap was as follow : < 5 mm (n=16), 5-10 mm (n=12), and > 10 mm (n=3). In patients with symptomatic osteochondroma, MR imaging is useful for detecting both complications and malignant transformation. (author). 21 refs., 1 tab., 6 figs.

    The aim of this study was to compare the morphology, radiological stage, conspicuity, and computer-assisted detection (CAD) characteristics of colorectal cancers (CRC) detected by computed tomographic colonography (CTC) in screening and symptomatic populations. Two radiologists independently analyzed CTC images from 133 patients diagnosed with CRC in (a) two randomized trials of symptomatic patients (35 patients with 36 tumours) and (b) a screening program using fecal occult blood testing (FOBt; 98 patients with 100 tumours), measuring tumour length, volume, morphology, radiological stage, and subjective conspicuity. A commercial CAD package was applied to both datasets. We compared CTC characteristics between screening and symptomatic populations with multivariable regression. Screen-detected CRC were significantly smaller (mean 3.0 vs 4.3 cm, p < 0.001), of lower volume (median 9.1 vs 23.2 cm 3 , p < 0.001) and more frequently polypoid (34/100, 34 % vs. 5/36, 13.9 %, p = 0.02) than symptomatic CRC. They were of earlier stage than symptomatic tumours (OR = 0.17, 95 %CI 0.07-0.41, p < 0.001), and were judged as significantly less conspicuous (mean conspicuity 54.1/100 vs. 72.8/100, p < 0.001). CAD detection was significantly lower for screen-detected (77.4 %; 95 %CI 67.9-84.7 %) than symptomatic CRC (96.9 %; 95 %CI 83.8-99.4 %, p = 0.02). Screen-detected CRC are significantly smaller, more frequently polypoid, subjectively less conspicuous, and less likely to be identified by CAD than those in symptomatic patients. (orig.)

    Objective: We compared the accuracy and tolerability of intravenous contrast enhanced spiral computed tomography colonography (CTC) and optical colonoscopy (OC) for the detection of colorectal neoplasia in symptomatic patients for colorectal neoplasia. Methods: A prospective study was performed in 48 patients with symptomatic patients with increased risk for colorectal cancer. Spiral CTC was performed in supine and prone positions after colonic cleansing. The axial, 2D MPR and virtual endoluminal views were analyzed. Results of spiral CTC were compared with OC which was done within 15 days. The psychometric tolerance test was asked to be performed for both CTC and colonoscopy after the procedure. Results: Ten lesions in 9 of 48 patients were found in CTC and confirmed with OC. Two masses and eight polyps, consisted of 1 tubulovillous, 1 tubular, 2 villous adenoma, 4 adenomatous polyp, 4 adenocarcinoma, were identified. Lesion prevalence was 21%. Sensitivity, specificity, accuracy, positive and negative predictive values were found 100%, 87%, 89%, 67% and 100%, respectively. Psychometric tolerance test showed that CTC significantly more comfortable comparing with OC (p = 0.00). CTC was the preferred method in 37% while OC was preferred in 6% of patients. In both techniques, the most unpleasant part was bowel cleansing. Conclusion: Contrast enhanced CTC is a highly accurate method in detecting colorectal lesions. Since the technique was found to be more comfortable and less time consuming compare to OE, it may be preferable in management of symptomatic patients with increased risk for colorectal cancer.

    Talc poudrage during thoracoscopy is considered the standard procedure for patients with symptomatic malignant pleural effusion (MPE). Until now, no alternative technique other than talc poudrage for pleurodesis during medical thoracoscopy has been proposed. Liquid sclerosants, such as mistletoe extract, have been sprayed evenly into the pleural cavity during semirigid pleuroscopy for chemical pleurodesis. We conducted a retrospective study using the database of semirigid pleuroscopy to identify the usefulness of pleurodesis using a mistletoe extract delivered via a spray catheter during semirigid pleuroscopy for symptomatic MPE. All consecutive patients with symptomatic MPE who underwent semirigid pleuroscopy from October 2015 to September 2016 were registered. The responses were evaluated using chest X- ray or computed tomography 4 weeks after pleurodesis. The study included 43 patients who underwent pleurodesis with mistletoe extract via a spray catheter during semirigid pleuroscopy. Complete and partial responses were seen in 21 (49%) and 19 (44%) patients, respectively. The median duration of chest tube placement after pleurod-esis was 7 days (range 6-8 days) in the 40 patients with complete or partial responses. No cases of severe hemorrhage, empyema formation, respiratory failure, or procedure-related mortality were observed in the subjects at 4 weeks after semirigid pleuroscopy. Pleurodesis with mistletoe extract delivered via a spray catheter during semirigid pleuroscopy is a safe and effective procedure for managing symptomatic MPE. © 2017 S. Karger AG, Basel.

    Full Text Available The quest for neuroprotective drugs to slow the progression of neurodegenerative diseases (NDDs, including Alzheimer's disease (AD, Parkinson's disease (PD, and Huntington's disease (HD, has been largely unrewarding. Preclinical evidence suggests that repurposing quetiapine, lithium, valproate, fluoxetine, donepezil, and memantine for early and pre-symptomatic disease-modification in NDDs may be promising and can spare regulatory barriers. The literature of these psychotropics in early stage and pre-symptomatic AD, PD, and HD is reviewed and propitious findings follow. Mild cognitive impairment (MCI phase of AD: salutary human randomized controlled trial findings for low-dose lithium and, in selected patients, donepezil await replication. Pre-symptomatic AD: human epidemiological data indicate that lithium reduces AD risk. Animal model studies (AMS reveal encouraging results for quetiapine, lithium, donepezil, and memantine. Early PD: valproate AMS findings show promise. Pre-symptomatic PD: lithium and valproate AMS findings are encouraging. Early HD: uncontrolled clinical data indicate non-progression with lithium, fluoxetine, donepezil, and memantine. Pre-symptomatic HD: lithium and valproate are auspicious in AMS. Many other promising findings awaiting replication (valproate in MCI; lithium, valproate, fluoxetine in pre-symptomatic AD; lithium in early PD; lithium, valproate, fluoxetine in pre-symptomatic PD; donepezil in early HD; lithium, fluoxetine, memantine in pre-symptomatic HD are reviewed. Dose- and stage-dependent effects are considered. Suggestions for signal-enhancement in human trials are provided for each NDD stage.

    Synovial cysts in an intraspinal location, associated with facet joint osteoarthritis, have been diagnosed using CT. Surgical removal of the cyst, when believed to be the cause of radiculopathy, has resulted in symptomatic relief. The authors have applied a nonoperative treatment method consisting of CT-guided needle placement in the facet joint adjacent to the cyst, followed by injection of contrast material and corticosteroids. Three patients were treated without complications and with complete relief of symptoms in two cases and partial relief in one, although no decrease in the size of the cysts was demonstrated on follow-up CT scans. The preliminary results indicate a possible role for this treatment technique in patients with intraspinal synovial cysts

    Full Text Available BACKGROUND: No reliable biomarkers are identified in KLS. However, few functional neuroimaging studies suggested hypoactivity in thalamic and hypothalamic regions during symptomatic episodes. Here, we investigated relative changes in regional brain metabolism in Kleine-Levin syndrome (KLS during symptomatic episodes and asymptomatic periods, as compared to healthy controls. METHODS: Four drug-free male patients with typical KLS and 15 healthy controls were included. 18-F-fluorodeoxy glucose positron emission tomography (PET was obtained in baseline condition in all participants, and during symptomatic episodes in KLS patients. All participants were asked to remain fully awake during the whole PET procedure. RESULTS: Between state-comparisons in KLS disclosed higher metabolism in paracentral, precentral, and postcentral areas, supplementary motor area, medial frontal gyrus, thalamus and putamen during symptomatic episodes, and decreased metabolism in occipital and temporal gyri. As compared to healthy control subjects, KLS patients in the asymptomatic phase consistently exhibited significant hypermetabolism in a wide cortical network including frontal and temporal cortices, posterior cingulate and precuneus, with no detected hypometabolism. In symptomatic KLS episodes, hypermetabolism was additionally found in orbital frontal and supplementary motor areas, insula and inferior parietal areas, and right caudate nucleus, and hypometabolism in the middle occipital gyrus and inferior parietal areas. CONCLUSION: Our results demonstrated significant hypermetabolism and few hypometabolism in specific but widespread brain regions in drug-free KLS patients at baseline and during symptomatic episodes, highlighting the behavioral state-dependent nature of changes in regional brain activity in KLS.

    Open curettage with bone graft has been the traditional surgical treatment for symptomatic unicameral calcaneal bone cyst. Endoscopic procedures have recently provided less invasive techniques with shorter postoperative morbidity. The authors' endoscopic procedure is effective for young athletes with symptomatic calcaneal bone cyst. Case series; Level of evidence, 4. Of 16 young athletes with symptomatic calcaneal bone cyst, 13 underwent endoscopic curettage and percutaneous injection of bone substitute under the new method. Three patients were excluded because of short-term follow-up, less than 24 months. For the remaining 10 patients, with a mean preoperative 3-dimensional size of 23 × 31 × 35 mm as calculated by computed tomography, clinical evaluation was made with the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale just before surgery and at the most recent follow-up (mean, 36.2 months; range, 24-51 months), and radiologic assessment was performed at the most recent follow-up, to discover any recurrence or pathologic fracture. Furthermore, the 10 patients-all of whom returned to sports activities-were asked how long it took to return to initial sports activity level after surgery. Mean ankle-hindfoot scale score improved from preoperative 78.7 ± 4.7 points (range, 74-87) to postoperative 98.0 ± 4.2 points (range, 90-100) (P < .001). Pain and functional scores significantly improved after surgery (P < .01 and P < .05, respectively). Radiologic assessment at most recent follow-up revealed no recurrence or pathologic fracture, with retention of injected calcium phosphate cement in all cases. All patients could return to their initial levels of sports activities within 8 weeks after surgery (mean period, 7.1 weeks; range, 4-8 weeks), which was quite early as compared with past reports. Endoscopic curettage and injection of bone substitute appears to be an excellent option for young athletes with symptomatic calcaneal bone cyst for early return

    The purpose of this study was to determine the prevalence of cuff tear and acromioclavicular joint (ACJ) osteoarthrosis by magnetic resonance imaging (MRI) evaluation in symptomatic shoulders. MRI was performed on 124 shoulders in 115 patients whose age ranged from 16 to 83 years (average: 58.0 years). There were 74 men (79 shoulders) and 41 women (45 shoulders). The patients were divided into three groups according to age; A group (10 shoulders: 16-29 years), B group (43 shoulders: 30-59 years), and C group (71 shoulders: 60-83 years). Rotator cuff tears and ACJ osteoarthrosis were graded on scales 0 to 3 (normal, increased signal intensity, incomplete, complete), and 1 to 4 (none, mild, moderate, severe), respectively. There was a significant difference in the severity of the cuff tears and the ACJ osteoarthrosis with respect to age. Twenty percent of the shoulders were graded incomplete or complete cuff tears in group A, 88% in group B, and 93% in group C. No shoulders were graded moderate or severe ACJ changes in group A, 63% in group B, and 93% in group C. There was a definite correlation between the cuff tears and ACJ osteoarthrosis. MRI of the symptomatic shoulders indicated well correlation between the rotator cuff tears and ACJ osteoarthrosis. (author)

    The behaviour of MOX fuel should be investigated in detail for more effective use in the future, especially concerning its thermal performance and fission gas release. IFA-597.4 and IFA-597.5, containing two MOX fuel rods each with a fuel centre thermocouple and a pressure transducer, have been irradiated in the Halden Reactor to study the temperature threshold of fission gas release for MOX fuel and to explore potential differences in the thermal and fission gas release behaviour between solid and hollow pellets. The two rods of MOX fuel with an initial Pu-fissile content of 6.07 percent have solid pellets and hollow pellets respectively, and with an active length of about 220 mm. The diameter of the pellets is 8.05 mm with 180μm of diametral gap to the cladding. For the purpose of the test, power ramp operation, in which estimated peak temperature of the MOX pellets increases and decreases above and below the threshold for fission gas release in UO 2 fuel, is planned every 10 MWd/kgMOX of burn-up. The first ramp operation has been successfully performed at 10 MWd/kgMOX. When the estimated peak temperature of the fuel gets close to but below the threshold of UO 2 , fission gas release was observed at around 28 kW/m of power. Densification of the MOX pellets could be estimated to about 1.2 percent for the solid pellets and about 2,3 percent for the hollow pellets from normalised internal rod pressure. After 13.5 MWd/kgMOX the average assembly power has been operated low enough to observe swelling rate of MOX fuel pellets and behaviour after significant fission gas release. The burn-up had reached 15.5 MWd/kgMOX as of the end of 1998. The target burn-up of this MOX test is 60 MWd/kgMOX (author) (ml)

    Many physicians remain uncertain about prescribing hormone therapy for symptomatic women at the onset of menopause. The American Society for Reproductive Medicine (ASRM) convened a multidisciplinary group of healthcare providers to discuss the efficacy and risks of hormone therapy for symptomatic women, and to determine whether it would be appropriate to treat women at the onset of menopause who were complaining of menopausal symptoms. Numerous controlled clinical trials consistently demonstrate that hormone therapy, administered via oral, transdermal, or vaginal routes, is the most effective treatment for vasomotor symptoms. Topical vaginal formulations of hormone therapy should be preferred when prescribing solely for the treatment of symptoms of vulvar and vaginal atrophy. Data from the Women's Health Initiative indicate that the overall attributable risk of invasive breast cancer in women receiving estrogen plus progestin was 8 more cases per 10,000 women-years. No increased risk for invasive breast cancer was detected for women who never used hormone therapy in the past or for those receiving estrogen only. Hormone therapy is not effective for the treatment of cardiovascular disease and that the risk of cardiovascular disease with hormone therapy is principally in older women who are considerably postmenopause. Healthy symptomatic women should be offered the option of hormone therapy for menopausal symptoms. Symptom relief with hormone therapy for many younger women (at the onset of menopause) with menopausal symptoms outweighs the risks and may provide an overall improvement in quality of life. Hormone therapy should be individualized for symptomatic women. This involves tailoring the regimen and dose to individual needs.

    Contrast-enhanced MR imaging of the spine after surgery for lumbar disk herniation almost always shows pathologic changes. To investigate to what extent these changes are correlated to patients' actual clinical symptoms, we compared the postoperative MR findings in 19 asymptomatic patients with 42 symptomatic patients (43 levels). The asymptomatic patients underwent MR examination one year after surgery. Twenty-six of the symptomatic patients underwent MR one year of less after surgery, and in 16 patients (17 levels) MR was performed more than one year after surgery. Sixteen percent of the asymptomatic and 42% of the symptomatic patients had disk herniation at the level of previous surgery. Most of the herniated disks were found in the symptomatic patients less than one year after surgery. The amount of epidural scar tissue, displacement and thickening of nerve roots, and compression of the dural sac were also studied. Disk herniation as a probable cause of recurrent sciatica was a common finding among symptomatic patients examined one year or less after surgery. In comparing asymptomatic patients and symptomatic patients with more than one year between surgery and MR examination, no significant radiologic differences, including disk herniation, were found.

    Optimization of coronary risk evaluation in stroke patients has been encouraged. The relationship between symptomatic intracranial atherosclerosis and occult coronary artery disease (CAD) has not been evaluated sufficiently. We aimed to investigate the prevalence of silent myocardial ischemia in patients with symptomatic intracranial atherosclerosis and to identify factors associated with its presence. From 186 first-ever transient ischemic attack or ischemic stroke patients with intracranial stenoses, 65 fulfilled selection criteria, including angiographic confirmation of a symptomatic atherosclerotic stenosis and absence of known CAD. All patients underwent a maximal-stress myocardial perfusion single-photon emission computed tomography (SPECT). Lipoprotein(a) [Lp(a)], C-reactive protein, and homocysteine (Hcy) levels were determined before SPECT. Stress-rest SPECT detected reversible myocardial perfusion defects in 34 (52%) patients. Vascular risk factors associated with a pathologic SPECT were hypercholesterolemia (P=0.045), presence of >2 risk factors (P=0.004) and high Lp(a) (P=0.023) and Hcy levels (P=0.018). Ninety percent of patients with high Lp(a) and Hcy levels had a positive SPECT. Existence of a stenosed intracranial internal carotid artery (ICA; odds ratio [OR], 7.22, 2.07 to 25.23; P=0.002) and location of the symptomatic stenosis in vertebrobasilar arteries (OR, 4.89, 1.19 to 20.12; P=0.027) were independently associated with silent myocardial ischemia after adjustment by age, sex, and risk factors. More than 50% of the patients with symptomatic intracranial atherosclerosis and not overt CAD show myocardial perfusion defects on stress-rest SPECT. Stenosed intracranial ICA, symptomatic vertebrobasilar stenosis and presence of high Lp(a) and Hcy levels may characterize the patients at a higher risk for occult CAD.

    The preferred method for revascularization of symptomatic infrapopliteal arterial occlusive disease (IPAD) has traditionally been open vascular bypass. Endovascular techniques have been increasingly applied to treat tibial disease with mixed results. We evaluated the short-term outcome of percutaneous infrapopliteal intervention and compared the different techniques used. A retrospective analysis of consecutive patients undergoing endovascular treatment for infrapopliteal arterial occlusive lesions between 2003 and 2007 in a tertiary teaching hospital was performed. Patient demographic data, indication for intervention, and periprocedural complications were recorded. Periprocedural and short-term outcomes were measured and compared. Forty-nine infrapopliteal arteries in 35 patients were treated. Twenty vessels (15 patients) underwent angioplasty and 29 vessels (20 patients) were treated with atherectomy. Demographic and angiographic characteristics were similar between the groups. Twenty-six patients had concurrent femoral and/or popliteal artery interventions. Overall, technical success was 90% and similar between angioplasty and atherectomy groups (85% versus 93%, p = NS). The vessel-specific complication rate was 10% and was similar between both groups (angioplasty 5% versus atherectomy 14%, p = NS). One dissection occurred in the angioplasty group; one perforation and three thromboembolic events occurred in the atherectomy group. Limb salvage and freedom from reintervention at 6 months were 81% and 68%, respectively, and were not significantly different between the angioplasty and atherectomy groups. Endovascular intervention for IPAD had acceptable periprocedural and short-term success rates in our high-risk patient population. Both atherectomy and angioplasty can be used successfully to treat symptomatic IPAD. PMID:22532766

    To determine the immediate and long-term results of endoscopic drainage and necrosectomy for symptomatic pancreatic fluid collections. The data of 80 patients with symptomatic pancreatic fluid collections (mean diameter: 11.7 cm, range 3-20; pseudocysts: 24/80, abscess: 20/80, infected walled-off necrosis: 36/80) referred for endoscopic management from October 1997 to March 2008 were analyzed retrospectively. Endoscopic drainage techniques included endoscopic ultrasound (EUS)-guided aspiration (2/80), EUS-guided transenteric drainage (70/80) and non-EUS-guided drainage across a spontaneous transenteric fistula (8/80). Endoscopic necrosectomy was carried out in 49/80 (abscesses: 14/20; infected necrosis: 35/36). Procedural complications were bleeding (12/80), perforation (7/80), portal air embolism (1/80) and Ogilvie Syndrome (1/80). Initial technical success was achieved in 78/80 (97.5%) and clinical resolution of the collections was achieved endoscopically in 67/80 (83.8%), with surgery required in 13/80 (perforation: four; endoscopically inaccessible areas: two; inadequate drainage: seven). Within 6 months five patients required surgery due to recurrent fluid collections; over a mean follow up of 31 months, surgery was required in four more patients due to recurrent collections as a consequence of underlying pancreatic duct abnormalities that could not be treated endoscopically. The long-term success of endoscopic treatment was 58/80 (72.5%). Endoscopic drainage of symptomatic pancreatic fluid collections is safe and effective, with excellent immediate and long-term results. Endoscopic necrosectomy has a risk of serious complications. The underlying pancreatic duct abnormalities must be addressed to prevent recurrence of fluid collections. © 2011 The Authors.

    This study sought to assess the success rate, effect on blood pressure, and pain of intraosseous injection (IO) and inferior alveolar nerve block (IANB) for pulpal anaesthesia of mandibular posterior teeth with symptomatic irreversible pulpitis as the primary anaesthetic technique. This randomized clinical trial (IRCT2013022712634N1) was conducted on 60 patients between 18 and 65 years suffering from symptomatic irreversible pulpitis of a mandibular posterior tooth. Patients were randomly divided into two groups. Group one received IO while group two received IANB with 3% mepivacaine. After anaesthetic injection, success rate of pulpal anaesthesia was assessed by pulp testing in the two groups. Systolic and diastolic blood pressures of patients were compared before and after the anaesthetic injections. Level of pain during injection was scored using a visual analogue scale. The data were analyzed using SPSS version 20, t-test and chi square test at p = .05 level of significance. Success rate of IO (56.7%) was significantly higher than that of IANB (23.3%) (p = .008). There was no significant difference in pain during anaesthetic injection (p = .304) or change in systolic (p = .80) and diastolic (p = .28) blood pressures following injection between the two techniques. IO had a higher success rate than IANB for pulpal anaesthesia of mandibular posterior teeth with symptomatic irreversible pulpitis. Neither technique provided profound pulpal anaesthesia.

    A nonlinear neural network that simultaneously uses pre-radiotherapy (RT) biological and physical data was developed to predict symptomatic lung injury. The input data were pre-RT pulmonary function, three-dimensional treatment plan doses and demographics. The output was a single value between 0 (asymptomatic) and 1 (symptomatic) to predict the likelihood that a particular patient would become symptomatic. The network was trained on data from 97 patients for 400 iterations with the goal to minimize the mean-squared error. Statistical analysis was performed on the resulting network to determine the model's accuracy. Results from the neural network were compared with those given by traditional linear discriminate analysis and the dose-volume histogram reduction (DVHR) scheme of Kutcher. Receiver-operator characteristic (ROC) analysis was performed on the resulting network which had Az=0.833±0.04. (Az is the area under the ROC curve.) Linear discriminate multivariate analysis yielded an Az=0.813±0.06. The DVHR method had Az=0.521±0.08. The network was also used to rank the significance of the input variables. Future studies will be conducted to improve network accuracy and to include functional imaging data. (author)

    Full Text Available Symptomatic dystonia can be the result of various metabolic, degenerative diseases, the consumption of certain medications or exposure to toxic agents. However, only symptomatic dystonia with focal structural lesion provides a significant "window" for, at least indirect, perception of aetiopa-thogenesis and pathomorphological substratum of idiopathic dystonia. Our study included 57 patients with symptomatic dystonia, which as a base had focal or multifocal lesions, of whom 7 patients had generalized dystonia, 18 hemidystonia, 6 segmental dystonia, 7 torticollis, 6 blepharospasm, 7 hand dystonia, 3 spasmodic dysphonia, and 3 had oromandibular dystonia. Stroke was highly statistically the most frequent cause of structural lesions (33/57 or 58%. Relevant pathomorphological changes were present in 50/57 (88% patients, of whom 25 (50% had lesion in the lenticular nucleus (including individual damage of the putamen and globus pallidus, 12/50 (24% had damage of the thalamus and 6/50 (12% had damage of the brainstem. Generalized dystonia was most frequently associated with bilateral lesion of the putamen, hemidystonia with lesion of contralateral putamen, torticollis with damage of the caudate nucleus, hand dystonia with lesion of the thalamus and blepharospasm with lesion of the upper brainstem.

    Symptomatic remission was defined as a score of mild or less on each of eight key schizophrenia symptoms on the Positive and Negative Syndrome Scale (PANSS-8). To evaluate the symptomatic remission criterion in clinical practice and to determine predictors for achieving symptomatic remission, a 12-week non-interventional study (NIS) with quetiapine was conducted in Germany. For the comparison of patients with and without symptomatic remission, sociodemographic and clinical variables of 693 patients were analyzed by logistic regression for their predictive value to achieve remission. Four hundred and four patients (58.3%) achieved symptomatic remission after 12 weeks' treatment with quetiapine. Remission was significantly predicted by a low degree of PANSS-8 total score, PANSS single items blunted affect (N1), social withdrawal (N4), lack of spontaneity (N6), mannerism and posturing (G5), and low disease severity (CGI-S) at baseline. Predictors of non-remission were older age, diagnosis of schizophrenic residuum, multiple previous episodes, longer duration of current episode, presence of concomitant diseases, and alcohol abuse. This study demonstrated that the majority of schizophrenia out-patients achieved symptomatic remission after 12 weeks treatment and confirms the importance of managing negative symptoms in order to achieve disease remission.

    The concept of symptomatic epilepsy and the difficulties in assigning cause in epilepsy are described. A historical review is given, emphasizing aspects of the history which are relevant today. The historical review is divided into three approximately semicentenial periods (1860-1910, 1910-1960, 1960-present). A definition of symptomatic epilepsy and this is followed by listing of causes of symptomatic epilepsy. The fact that not all the causes of idiopathic epilepsy are genetic is discussed. A category of provoked epilepsy is proposed. The complexities in assigning cause include the following: the multifactorial nature of epilepsy, the distinction between remote and proximate causes, the role of nongenetic factors in idiopathic epilepsy, the role of investigation in determining the range of causes, the fact that not all symptomatic epilepsy is acquired, the nosological position of provoked epilepsy and the view of epilepsy as a process, and the differentiation of new-onset and established epilepsy. The newly proposed ILAE classification of epilepsy and its changes in terminologies and the difficulties in the concept of acute symptomatic epilepsy are discussed, including the inconsistencies and gray areas and the distinction between idiopathic, symptomatic, and provoked epilepsies. Points to be considered in future work are listed. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Exposure to influenza viruses is necessary, but not sufficient, for healthy human hosts to develop symptomatic illness. The host response is an important determinant of disease progression. In order to delineate host molecular responses that differentiate symptomatic and asymptomatic Influenza A infection, we inoculated 17 healthy adults with live influenza (H3N2/Wisconsin and examined changes in host peripheral blood gene expression at 16 timepoints over 132 hours. Here we present distinct transcriptional dynamics of host responses unique to asymptomatic and symptomatic infections. We show that symptomatic hosts invoke, simultaneously, multiple pattern recognition receptors-mediated antiviral and inflammatory responses that may relate to virus-induced oxidative stress. In contrast, asymptomatic subjects tightly regulate these responses and exhibit elevated expression of genes that function in antioxidant responses and cell-mediated responses. We reveal an ab initio molecular signature that strongly correlates to symptomatic clinical disease and biomarkers whose expression patterns best discriminate early from late phases of infection. Our results establish a temporal pattern of host molecular responses that differentiates symptomatic from asymptomatic infections and reveals an asymptomatic host-unique non-passive response signature, suggesting novel putative molecular targets for both prognostic assessment and ameliorative therapeutic intervention in seasonal and pandemic influenza.

    Fuel assembly IFA-204 consisted of four pins filled with a blend of three sizes of UO 2 spheres. This blend was compacted in the zircaloy-4 cladding tube by vibration to achieve a 87-88% T.D. smear density of the 1500 mm long sphere-pac fuel column. IFA-204 was irradiated during 597 days, equivalent to 436 full power days, in the Halden BWR from November 1971 to April 1974 when the achieved assembly average burnup amounted to 13.7 MWd/kg UO 2 . Two of the four pins were equipped with fuel column length and pin length extensometers. The measurements showed that at average pin powers less than about 25 kW.m -1 only fuel-clad-thermal-interaction, FCTI, occurred. The clad thermal expansion coefficient was 4.8 ppm/kW.m -1 . For calculations of the irradiation behaviour of sphere-pac LWR pins, filled with 0.1 MPa helium, with the Gapcon-Thermal-2 code a new thermal conductivity-temperature relationship has been developed. The calculated data agreed reasonably well with the measured data when taking into account a restructured fuel density of 90% T.D., a fuel surface roughness of 1 μm, the absence of a fuel-cladding gap and an effective full power fuel restructuring time of 40 days. It is concluded that the porous structure of the sphere-pac fuel column, whether restructured or not, has the inherent disadvantage of a high mobility of gaseous fission products and the inherent advantage of a practically stress free operation of the cladding

    The concept of symptomatic and functional remission represents an important challenge in the care of the mentally ill, particularly in patients with schizophrenia. Operational criteria for symptomatic remission in schizophrenia have been proposed by Andreasen et al. (2005). Over the last decade, these criteria have been widely validated; however few studies have been conducted outside developed countries. Moreover, the association of symptomatic remission with functional outcome has not yet been established in developing countries including Tunisia, as there may be variability in the social and familial environment. To determine the frequency and associated factors of symptomatic remission in a sample of Tunisian out-patients with schizophrenia and to explore the relationship between symptomatic remission and some indicators of social functioning. A cross-sectional study was carried-out on 115 out-patients with schizophrenia (87 males, 28 females, mean age=37.56±10.2 years) in the psychiatry department of the university hospital in Monastir (Tunisia). Nearly all of the patients (98.26%) had been hospitalized at least once in a psychiatric unit. The last hospitalization dated back to 39 months on average (range=6 months to 16 years). Symptomatic remission was assessed by the eight core items of the positive and negative syndrome scale (PANSS). These are the items P1 "Delusions"; P3 "Hallucinatory behavior" and G9 "Unusual thought content" for the positive dimension, the items P2 "Conceptual disorganization" and G5 "Mannerism and disorders of posture" for the disorganization dimension and the items N1 "Blunted affect", N4 "Social withdrawal" and N6 "Lack of spontaneity and flow of conversation" for the negative dimension. A score of mild or less on all eight-core symptoms constitutes symptomatic remission. This symptom level should have been maintained for six months. The social functioning was assessed by the Social and Occupational Functioning Assessment Scale

    We analyzed clinical factors related to uptake on a Tc-99 m HDP bone scan of the accessory navicular (AN). We retrospectively reviewed patients who had been examined by an orthopedic surgeon and underwent bone scan due to suspected symptomatic AN. A three-point grading system was used to evaluate uptake on bone scan. Relationships between grade, symptoms, age, gender, symptom duration, and bone size were analyzed. In total, 73 ANs (30 asymptomatic, 43 symptomatic) were enrolled. The majority of asymptomatic ANs had no uptake but some had grade 1 (n = 8) or 2 (n = 2) uptake. All asymptomatic ANs with uptake remained asymptomatic during follow-up. For the asymptomatic ANs, larger bones showed a higher grade. With a cut-off value of size ≤6.8 mm, there is no chance of uptake. All symptomatic ANs showed uptake on bone scan. For symptomatic ANs, larger size and shorter pain duration were related to a higher grade. Age, gender, and left-/right-sideness were not related to grade. Multiple regressions revealed that only uptake grade, not size or symptom duration, was the significant risk factor for a symptomatic AN. With a cut-off value of grade <1, a symptomatic AN could be ruled out with a negative predictive value of 100 %. Bone scanning is useful for symptomatic ANs with a high negative predictive value. Higher grade is related to larger size and shorter pain duration. For asymptomatic ANs, grade was related to size but did not predict symptom development

    We quantitatively evaluated the effects of landscape factors on the distribution of symptomatic raccoon dogs with sarcoptic mange along an urban gradient. We used 246 camera traps (182 traps from April 2005 to December 2006; 64 traps from September 2009 to October 2010) to record the occurrence of asymptomatic and symptomatic raccoon dogs at 21 survey sites along an urban-rural gradient in the Tama Hills area of Tokyo. Each occurrence was explained in terms of the surrounding forest, agricultural, and grassland areas and additional factors (i.e., seasonal variations and survey methods) at various spatial scales using a generalized additive mixed model (GAMM). In our analysis, a 1000-m radius was identified as the important spatial scale for asymptomatic and symptomatic raccoon dog occurrence. The peak of the predicted occurrence probability of asymptomatic raccoon dogs appeared in the intermediate forest landscape as opposed to non-forest and forest landscapes. However, a high occurrence probability of symptomatic raccoon dogs was detected in non-forest and intermediate forest landscapes (i.e., urban and suburban) as opposed to a forest landscape, presumably because of animals occurring at much higher densities in more urbanized areas. Therefore, our results suggest that human-modified landscapes play an important role in the high occurrence of sarcoptic mange in raccoon dogs.

    Despite the upsurge of research regarding cognitive impairment in schizophrenia we still lack adequate understanding of the executive functioning of patients in symptomatic remission. Moreover, the cognitive functioning of patients in partial remission has not been studied previously although they comprise a significant proportion of schizophrenia patients. The current study therefore examined the executive functioning of patients in full symptomatic remission and for the first time assessed two sub-groups of patients in partial remission. Executive functioning of five groups was compared; symptomatic patients, patients in positive symptomatic remission, negative symptomatic remission, full symptomatic remission (SP, PSR, NSR, and FSR; N=101) and healthy controls (N=37). A graded cognitive profile was evident between the groups. SP patients exhibited widespread executive dysfunction while the performance of FSR patients was comparable to that of the healthy controls. Both PSR and NSR patients had working memory deficits, with PSR patients showing additional deficits in cognitive planning. The findings are encouraging, tentatively suggesting intact executive functioning among patients in full symptomatic remission. The graded cognitive profile of the patient groups strengthens earlier findings indicating the significant role of negative symptoms in determining executive dysfunction in schizophrenia. The findings point toward potential targets for therapeutic efforts and emphasize the need for further research of sub-groups of schizophrenia patients in partial remission.

    Full Text Available Cytomegalovirus (CMV is the most frequent congenital virus infection worldwide. The risk of congenital CMV (cCMV transmission is highest in seronegative women who acquire primary CMV infection during pregnancy. A growing body of evidence indicates that secondary CMV infections in pregnant women with preconceptual immunity (either through reactivation of latent virus or re-infection with a new strain of CMV contribute to a much greater proportion of symptomatic cCMV than was previously thought. Here, we describe a case of symptomatic cCMV infection in the newborn of a woman with proven immunity prior to pregnancy. Diagnosis was confirmed by CMV PCR from amniotic fluid and fetal MR imaging. The newborn presented with typical cCMV symptoms including jaundice, hepatosplenomegaly, cholestasis, petechiae, small head circumference, and sensorineural hearing loss, the most common neurologic sequela. CMV was detected in infant blood and urine by PCR, and intravenous ganciclovir was initiated and continued orally for 6 weeks totally. Apart from persisting right-sided deafness, the child exhibited normal neurological development up through the last follow-up at 4.5 years. To date, the most effective strategy to prevent vertical CMV transmission is hygiene counseling for women of childbearing age, which, in our case, and in concordance with recent literature, applies to seronegative, as well as seropositive, women. Once an expecting mother shows seroconversion or signs of an active CMV infection, there are no established procedures to reduce the risk of transmission, or therapeutic options for the fetus with signs of infection. After birth, symptomatic infants can be treated with ganciclovir to inhibit viral replication and improve hearing ability and neurodevelopmental outcome. A comprehensive review of the literature, including our case study, reveals the most current and significant diagnostic and treatment options available. In conclusion, the triad

    The outcome evaluation for the revascularization of intracranial vascular stenoses has not been fully described due to the highly technical nature of the procedure. We report here on the early and late clinical outcome of angioplasty and/or stenting of symptomatic severe intracranial vascular stenoses at a single institute. Since 1995, we have treated 35 patients with symptomatic intracranial vascular stenosis (more than 70% stenosis, mean stenosis: 78.6% {+-} 6.2%). Angioplasty (n = 19) was performed for the horizontal segment of the middle cerebral artery (M1) (n = 16) and the basilar artery (BA) (n = 1), the intradural vertebral artery (VA) (n = 1), and the cavernous internal carotid artery (ICA) (n = 1). Stenting (n = 16) was performed for the cavernous or petrous ICAs (n = 9), the intradural VA (n = 3), BA (n = 2), and M1 (n = 2) artery. We assessed the angiographic success (defined as residual stenosis < 50%) rate, the periprocedural complications during the 30-day periprocedural period, the symptomatic recurrence and restenosis during a mean 22-month follow-up (FU) period. The Kaplan-Meier estimate of the cumulative even-free rate of the major cerebrovascular events, i.e. death, stroke or restenosis, was also done. Angiographic success was achieved in 97% of our patients (34/35). There were four procedure-related complications (11%) including a death and a minor stroke. During the mean 22-month FU, the asymptomatic restenosis rate was 9% and the symptomatic restenosis rate was 6% in the target lesion and 9% in all the vascular territories. The Kaplan-Meier estimate was 70.6% (95% confidence interval = 46.5-94.7) after 33 month of FU. In addition to a high angiographic success rate and an acceptable periprocedural complication rate, intracranial angioplasty and/or stenting revealed a relatively low symptomatic recurrence rate. Hemorrhage is a rare, but the physician must aware that potentially fatal periprocedural complications can occur.

    The ability of alliance to predict outcome has been widely demonstrated, but less is known about the effect of the level of congruence between patient and therapist alliance ratings on outcome. In the current study we examined whether the degree of congruence between patient and therapist alliance ratings can predict symptomatic levels 1 month later in treatment. The sample consisted of 127 patient-therapist dyads. Patients and therapists reported on their alliance levels, and patients reported their symptomatic levels 1 month later. Polynomial regression and response surface analysis were used to examine congruence. Findings suggest that when the congruence level of patient and therapist alliance ratings was not taken into account, only the therapist's alliance served as a significant predictor of symptomatic levels. But when the degree of congruence between patient and therapist alliance ratings was considered, the degree of congruence was a significant predictor of symptomatic levels 1 month later in treatment. Findings support the importance of the level of congruence between patient and therapist alliance ratings in predicting patient's symptomatic levels.

    The aim of this study is to assess the levels and diagnostic accuracy of a set of bone resorption biomarkers, including TRAP-5, RANKL, and OPG in symptomatic and asymptomatic apical lesions and controls. Apical tissues from symptomatic and asymptomatic apical periodontitis patients and periodontal ligaments from healthy teeth extracted for orthodontic reasons were processed for tissue homogenization and the levels of TRAP-5, RANKL, and OPG were determined by multiplex assay. Marker levels were analyzed by Kruskal Wallis test, and diagnostic accuracy was analyzed with ROC curves. Higher levels of RANKL, OPG, and RANKL/OPG ratio were determined in both types of apical lesions compared to healthy periodontal ligament, whereas higher TRAP-5 levels were found only in symptomatic apical lesions (p apical lesions versus healthy controls (AUC = 0.69, p asymptomatic apical periodontitis (AUC = 0.71, p Apical lesions showed higher RANKL and OPG levels than healthy tissues. TRAP-5 levels were the highest in symptomatic apical lesions, suggesting that these represent a progressive state, and showed diagnostic potential. Clinically symptomatic apical periodontitis might represent biologically progressive apical lesions based on TRAP5 levels. TRAP5 has diagnostic potential to identify these lesions, representing a candidate prognostic biomarker.

    A series of fuel rod irradiation experiments were performed in the Halden Heavy Boiling Water Reactor in Norway. These were designed to provide a range of fuel property data as a function of burn-up. One of these experiments was the IFA-429. This was designed to study the absorption of helium filling gas by the UO 2 fuel pellets, steady state and transient fission gas release and fuel thermal behaviour to high burn-up. This data was to be obtained as a function of fuel density, fuel grain size, initial fuel/cladding gap, average linear heat rating, burn-up and overpower transients. All the fuel is in the form of pressed and sintered UO 2 pellets enriched to 13 weight percent 235 U. All the rods were clad in Zircaloy 4 tube. The details of the experiment are given. The post irradiation examination included: visual examination, neutron radiography, dimensional measurements, gamma scanning, measurement of gases in fuel rods and internal free volume, burn-up analysis, metallographic examination, measurement of retained gas in UO 2 pellets, measurement of bulk density of UO 2 . The results are given and discussed. (U.K.)

    To test the hypothesis that a common iliac vein (CIV) stenosis may impair embolization of a large deep venous thrombosis (DVT) to the lungs, decreasing the incidence of a symptomatic pulmonary embolism (PE). Between January 2002 and August 2007, 75 patients diagnosed with unilateral DVT were included in a single-institution case-control study. Minimum CIV diameters were measured 1 cm below the inferior vena cava (IVC) bifurcation on computed tomography (CT) images. A significant stenosis in the CIV ipsilateral to the DVT was defined as having either a diameter 4 mm or less or a greater than 70% reduction in lumen diameter. A symptomatic PE was defined as having symptoms and imaging findings consistent with a PE. The odds of symptomatic PE versus CIV stenosis were assessed using logistic regression models. The associations between thrombus location, stenosis, and symptomatic PE were assessed using a stratified analysis. Of 75 subjects, 49 (65%) presented with symptomatic PE. There were 17 (23%) subjects with a venous lumen 4 mm or less and 12 (16%) subjects with a greater than 70% stenosis. CIV stenosis of 4 mm or less resulted in a decreased odds of a symptomatic PE compared with a lumen greater than 4 mm (odds ratio [OR] 0.17, P = .011), whereas a greater than 70% stenosis increased the odds of DVT involving the CIV (OR 7.1, P = .047). Among patients with unilateral DVT, those with an ipsilateral CIV lumen of 4 mm or less have an 83% lower risk of developing symptomatic PE compared with patients with a CIV lumen greater than 4 mm.

    Hemorrhoids are the most common anorectal complaint, and approximately 10 to 20 percent of patients with symptomatic hemorrhoids require surgery. Symptoms of hemorrhoids, such as painless rectal bleeding, tissue protrusion and mucous discharge, vary. The traditional therapeutic strategies of medicine include surgical, as well as non-surgical, treatment. To alleviate symptoms caused by hemorrhoids, oral treatments, such as fiber, suppositories and Sitz baths have been applied to patients. Othe...

    Objective: To differentiate MR imaging characteristics of symptomatic as compared with asymptomatic Achilles tendons.Design: 1.5 T MR images of 94 feet (88 patients) with ''abnormal'' MR examinations were retrospectively evaluated and clinically correlated. Two masked, independent observers systematically evaluated for intratendon T2 signal, tendon thickness, presence of peritendonitis, retrocalcaneal bursal fluid volume, pre-Achilles edema, bone marrow edema at the Achilles insertion, and tears (interstitial, partial, complete). These findings were correlated with symptoms (onset and duration) and physical examination results (tenderness, palpable defects, increased angle of resting dorsiflexion).Results: Of the 94 ankles, 64 ankles (32 females, 29 males) were clinically symptomatic. No relationship between Achilles tendon disorders and age or gender was identified. Asymptomatic Achilles tendons frequently demonstrated mild increased intratendon signal (21/30), 0.747 cm average tendon thickness, peritendonitis (11/30), pre-Achilles edema (12/30), and 0.104 ml average retrocalcaneal bursal fluid volume. Symptomatic patients had thicker tendons (0.877 cm), greater retrocalcaneal fluid volume (0.278 ml), more frequent tears (23/64), a similar frequency of peritendonitis (22/64) but less frequent pre-Achilles edema (18/64). Sixty-four percent of the Achilles tendon tears were interstitial. Except for two interstitial tears in control patients, the majority of Achilles tears were in symptomatic patients (14/16). Only symptomatic tendons demonstrated partial or complete tendon tears. In addition, calcaneal edema was found almost exclusively in actively symptomatic patients. Thicker tendons were associated more often with chronic symptoms and with tears. When present in symptomatic patients, peritendonitis was usually associated with acute symptoms. The presence of pre-Achilles edema, however, did not distinguish acute from chronic disorders.Conclusion: There is

    This study was performed to determine the prevalence of bifid mandibular condyles (BMCs) in asymptomatic and symptomatic temporomandibular joint (TMJ) subjects with no traumatic history, and to assess their impact on clinical and radiographic manifestations of TMJ. A total of 3,046 asymptomatic and 4,378 symptomatic patients were included in the study. Cone-beam computed tomography (CBCT) images were reviewed for bifid condyles. T-tests were used to compare the frequency of BMCs when stratified by symptom, gender, and side. In BMC patients, the clinical features of pain and noise, osseous changes, and parasagittal positioning of the condyles were compared between the normally shaped condyle side and the BMC side using chi-squared tests. Fifteen (0.49%) asymptomatic and 22 (0.50%) symptomatic patients were found to have BMCs. Among the bilateral cases, the number of condyles were 19 (0.31%) and 25 (0.29%), respectively. No statistically significant differences were found between asymptomatic and symptomatic patients, between female and male patients, or between the right and left sides (p>0.05). Compared with the normally shaped condyle side, the BMC side showed no statistically significant differences in the distribution of pain and noise, parasagittal condylar position, or condylar osseous changes, with the exception of osteophytes. In the symptomatic group, osteophytes were found more frequently on the normally shaped condyle side than the BMC side (p<0.05). BMCs tended to be identified as an incidental finding. The presence of BMC would not lead to any TMJ symptoms or cause osseous changes.

    We report on a 33-year-old man with symptomatic heterotopic suprarenal splenic tissue. Heterotopic splenic tissue can often be found after posttraumatic splenectomy. It is a result of autotransplantation induced by trauma (splenosis). Additionally it can grow during embryogenic development. Such an accessory spleen is found in 10-44% of all autopsies. In this case report the patient was treated by resection due to increasing flank pain and suspected neoplasm. (orig.) [de

    In order to improve the accident tolerance of light water reactor (LWR) fuel, alternative cladding materials have been proposed to replace the currently used zirconium (Zr)-based alloys. Of these materials, there is a particular focus on iron-chromiumaluminum (FeCrAl) alloys because they exhibit slower oxidation kinetics in high-temperature steam than Zr-alloys. This should decrease the energy release due to oxidation and slow cladding consumption in the presence of high temperature steam. These alloys should also exhibit increased “coping time” in the event of an accident scenario by improving the mechanical performance at high temperatures, allowing greater flexibility to achieve core cooling. As a continuation of the development of these alloys, in-reactor irradiation testing of FeCrAl cladded fuel rods has started. In order to provide insight on the possible behavior of these fuel rods as they undergo irradiation in the Halden Boiling Water Reactor, engineering analysis has been performed using FeCrAl material models implemented into the BISON fuel performance code. This milestone report provides an update on the ongoing development of modeling capability to predict FeCrAl cladding fuel performance and to provide an early look at the possible behavior of planned in-reactor FeCrAl cladding experiments. In particular, this report consists of two separate analyses. The first analysis consists of fuel performance simulations of IFA-796 rod 4 and two segments of rod 3. These simulations utilize previously implemented material models for the C35M FeCrAl alloy and UO2 to provide a bounding behavior analysis corresponding to variation of the initial fuel cladding gap thickness within the fuel rod. The second analysis is an assessment of the fuel and cladding stress states after modification of the fuel creep model that is currently implemented in the BISON fuel performance code. Effects from modifying the fuel creep model were identified for the BISON simulations

    Current management of renal angiomyolipomas (AMLs) include observation, transcatheter embolization and partial or total nephrectomy. Patients symptoms and size of the lesion are the determinants for the choice of the treatment. In general symptomatic or greater than 8 cm masses require intervention. A retrospective study of five patients presented with symptomatic lesions and treated with selective transcatheter embolization, over a 3 year period was performed in our hospital. A total of eight embolizations were performed, all on an emergency basis due to retroperitoneal bleeding or significant hematuria. Surgical intervention was necessary in one case, due to massive rebleeding on the fourth post-procedural day. Two patients rebled within 6 months and 2 years respectively, and were managed successfully with additional embolization. The remaining two patients are still asymptomatic 26 and 18 months after the successful initial result. Experience with this procedure is reported on with emphasis to the clinical outcome. It is believed that selective arterial embolization should be the standard initial therapy for symptomatic renal AMLs.

    The occurrence of human herpesvirus (HHV) 6 subtypes A and B in apical periodontitis was determined. The relationship of HHV-6 subtypes to other disease associated herpesviruses, i.e., Epstein-Barr virus (EBV) and human cytomegalovirus, was also investigated. Forty apical periodontitis samples (17 symptomatic and 23 asymptomatic) and 40 healthy pulp control samples were collected. Nested polymerase chain reaction was used to detect HHV-6 DNA. HHV-6 DNA was observed in significantly higher frequencies in apical periodontitis samples than in control samples (20% vs. 2.5%; P = .03). Further classification of apical lesions revealed that subtype B of HHV-6 was significantly associated with large-sized and symptomatic lesions (P apical lesions (77%) harbored ≥1 of the tested herpesviruses: EBV was the most frequent herpesvirus (72.5%) in apical periodontitis, followed by HHV-6 (20%). Our findings suggest that EBV and HHV-6B infections can be associated with symptomatic apical periodontitis. Copyright © 2011 Mosby, Inc. All rights reserved.

    One hundred eleven patients with symptomatic prosthetic joints (86 hips, 23 knees, and two shoulders) were evaluated for prosthetic loosening and infection by combined technetium-99m-MDP/gallium-67 digital subtraction imaging. Clinical correlation was based on the assessment of loosening and bacterial cultures obtained at the time of surgery in 54 patients, joint aspiration cultures obtained in 37 patients, and long-term clinical follow-up for greater than 1.5 years in an additional 15 patients. Results revealed an 80-90% predictive value of a positive test for loosening, and a 95% predictive value of a negative test for infection. However, because of the low sensitivities and specificities observed, this approach to the evaluation of symptomatic prosthetic joints does not seem cost effective

    Objective: To explore the causes and preventive measures of symptomatic intracranial hemorrhage in 217 patients with acute cerebral ischemic stroke treated with local intra-arterial urokinase. Methods: From February 1999 to June 2004, 217 patients were treated for acute ischemic stroke with local intra-arterial urokinase in our hospital. Factors associated with symptomatic intracranial hemorrhage of intra-arterial thrombolysis were analyzed by Stepwise logistic regression to identify some factors relating the prediction symptomatic intracranial hemorrhage. Results: Symptomatic intracranial hemorrhage occurred in 8 cases (3.7%). Predictors of the symptomatic intracranial hemorrhage were the elevated systolic blood pressure before therapy (odds ratio, 1.096; 95% CI, 1.006 to 1.194) and urokinase (UK) treatment (odds ratio, 1.068 ; 95% CL, 1.053 to 1.247). Risk of secondary symptomatic intracranial hemorrhage was increased with elevated systolic blood pressure. Other factors like age, initial treating time, NIHSS, diabetes and collateral circulation did not predict the symptomatic intracranial hemorrhage respectively. Conclusions: Predictors of symptomatic intracranial hemorrhage after local intra-arterial infusion of urokinase for acute ischemic stroke were the elevated systolic blood pressure before therapy and urokinase (UK) treatment.

    Bovine neosporosis is caused by the protozoan Neospora caninum and is one of the major causes of abortion in cows. Cattle are intermediate hosts of this parasite and may have asymptomatic or symptomatic infections. Therefore, the aim of this study was to evaluate oxidative stress marker reactive oxygen species (ROS), thiobarbituric reactive acid substances (TBARS) levels, glutathione S-transferase (GST), adenosine deaminase (ADA), and butyrylcholinesterase (BChE) activities in dairy cows seropositives for N. caninum (asymptomatic or symptomatic). Dairy cows (n=90) were tested by immunofluorescent antibody assay (IFA) for N. caninum and divided accordingly into three groups: the group A (seronegatives, n=30), the group B (seropositives and asymptomatic, n=30), and the group C (seropositives and symptomatic, n=30). It was observed increased levels of TBARS and reduced (Pcows (the group C) compared to seronegatives dairy cows (the group A). Based on these results, it was observed that seropositive animals showed cell damage associated with oxidative stress and inflammation, mainly in those with symptomatic infections. Increased seric ROS levels and BChE activity may have influenced N. caninum pathogenesis in symptomatic animals due to increased cell damage and exacerbated inflammatory response, leading to the development of clinical signs.

    Full Text Available AIM: To evaluate the effectiveness of the Crawford tube in treating symptomatic epiphora without nasolacrimal obstruction. METHODS: A protocol was adopted for the management of symptomatic epiphora without nasolacrimal obstruction. Patients who suffered symptomatic epiphora without nasolacrimal obstruction in both eyes were included in the study. One eye was treated with Crawford tube intubation and the other eye was treated with medication therapy. Degree of watering, patient satisfaction, and symptomatic improvement were carefully evaluated by one of the authors at the end of the follow-up period, after Crawford tube removal, to ascertain functional results. RESULTS: Thirty-seven adult patients (37 eyes underwent Crawford tube intubation for functional epiphora. The mean follow-up time after removal of the tube was 14.8±4.8mo. The procedure was an overall success in 28 eyes (75.7%, with symptoms improving significantly. Two eyes (5.4% were relieved of indoor epiphora, two (5.4% had minimal epiphora outdoors, but only with wind or cold, and five (13.5% continued to experience tearing both indoors and outdoors. Thirty of the patients (81% expressed satisfaction with the procedure. CONCLUSION: Crawford tube insertion is an effective, safe, simple, and relatively noninvasive treatment strategy for functional lacrimal system obstruction.

    To identify differences in health factors, neuromuscular attributes, and performance-based mobility among community-dwelling older adults with symptomatic lumbar spinal stenosis; and to determine which neuromuscular attributes are associated with performance-based measures of mobility. Cross-sectional; secondary data analysis of a cohort study. Outpatient rehabilitation center. Community-dwelling adults aged ≥65 years with self-reported mobility limitations and symptomatic lumbar spinal stenosis (N=54). Not applicable. Short Physical Performance Battery score, habitual gait speed, and chair stand test. Symptomatic lumbar spinal stenosis was classified using self-reported symptoms of neurogenic claudication and imaging. Among 430 community-dwelling older adults, 54 (13%) met criteria for symptomatic lumbar spinal stenosis. Compared with participants without symptomatic lumbar spinal stenosis, those with symptomatic lumbar spinal stenosis had more comorbidities, higher body mass index, greater pain, and less balance confidence. Participants with symptomatic lumbar spinal stenosis had greater impairment in trunk extensor muscle endurance, leg strength, leg strength asymmetry, knee flexion range of motion (ROM), knee extension ROM, and ankle ROM compared with participants without symptomatic lumbar spinal stenosis. Five neuromuscular attributes were associated with performance-based mobility among participants with symptomatic lumbar spinal stenosis: trunk extensor muscle endurance, leg strength, leg strength asymmetry, knee flexion ROM, and knee extension ROM asymmetry. Community-dwelling older adults with self-reported mobility limitations and symptomatic lumbar spinal stenosis exhibit poorer health characteristics, greater neuromuscular impairment, and worse mobility when compared with those without symptomatic lumbar spinal stenosis. Poorer trunk extensor muscle endurance, leg strength, leg strength asymmetry, knee flexion ROM, and knee extension ROM asymmetry

    The aim of the present study was to investigate the nitrous oxide (N 2 O) emissions from a moving bed based Integrated Fixed Film Activated Sludge (IFAS) - membrane bioreactor (MBR) pilot plant, designed according to the University of Cape Town (UCT) layout. The experimental campaign had a duration of 110 days and was characterized by three different sludge retention time (SRT) values (∞, 30 d and 15 d). Results highlighted that N 2 O concentrations decreased when the biofilm concentrations increased within the aerobic reactor. Results have shown an increase of N 2 O with the decrease of SRT. Specifically, an increase of N 2 O-N emission factor occurred with the decrease of the SRT (0.13%, 0.21% and 0.76% of influent nitrogen for SRT = ∞, SRT = 30 d and SRT = 15 d, respectively). Moreover, the MBR tank resulted the key emission source (up to 70% of the total N 2 O emission during SRT = ∞ period) whereas the highest N 2 O production occurred in the anoxic reactor. Moreover, N 2 O concentrations measured in the permeate flow were not negligible, thus highlighting its potential detrimental contribution for the receiving water body. The role of each plant reactor as N 2 O-N producer/consumer varies with the SRT variation, indeed the aerobic reactor was a N 2 O consumer at SRT = ∞ and a producer at SRT = 30 d.

    Symptomatic splenic hamartomas are rare in the pediatric age group, with only four previous reports in the literature. Splenic hamartoma has been reported as a solid homogeneous mass without calcification on CT and ultrasound (US), and only one previous report of the findings on MRI has been published. We report a case of a large symptomatic splenic hamartoma in a 14-year-old girl who presented with splenomegaly, pancytopenia and growth retardation. A solid mass with multiple punctate foci resembling calcifications was seen on US. The mass was heterogeneous and better demarcated on enhanced CT. Radiocolloid scintigraphy demonstrated uptake within the lesion, but less than that of normal spleen. The mass was isointense relative to normal splenic tissue on T1-weighted MRI (0.5 T) and of increased intensity with T2 weighting. At splenectomy, a red pulp hamartoma was identified, which contained nodules of hyalinization and necrosis thought to account for the punctate foci seen on US. (orig.). With 4 figs

    Full Text Available AimDefinitive surgery of ectopic ureter in infants is challenging. We propose an endoscopic urinary diversion (EUD as a novel surgical technique in the initial management of symptomatic obstructive ectopic ureter.Patients and methodsSixteen obstructive ectopic ureters (14 patients were initially treated by EUD between 2006 and 2015. All patients had urinary tract dilatation worsening at preoperative US scans and at least two febrile urinary tract infection (UTI or urinary sepsis despite antibiotic prophylaxis. Ectopic ureter was confirmed by cystoscopy. When ectopic meatus was not found, EUD consisted in the creation of a transurethral neo-orifice (TUNO performed by needle puncturing of the ureterovesical wall, under fluoroscopic and ultrasound control. If ectopic meatus was identified in the posterior urethra, “intravesicalization procedure” was done opening the urethral–ureteral wall to create a new ureteral outlet into the bladder.ResultsEUD was done at a median age of 3.5 months (0.5–7 with median follow-up of 48 months (24–136. TUNO was performed in six patients and “intravesicalization” in eight patients. Significant differences were observed in ureteral diameter and anteroposterior pelvis diameter before and after endoscopic treatment (p < 0.005. Initial renal function was preserved in all cases. Postoperative complications were UTI in four patients and TUNO stenosis in one patient, treated by endoscopic balloon dilation. Definitive treatment was further individualized in each patient after 1 year of life.ConclusionEUD is a feasible and safe less-invasive technique in the initial management of symptomatic obstructive ectopic ureter. It allows an adequate ureteral drainage preserving renal function until definitive repair if necessary and does not invalidate other surgical options in case of failure or future definitive treatments.

    Full Text Available OBJECTIVE: To compare the success, efficacy and complications of ureteroscopy (URS and extra corporeal shock wave lithotripsy (ESWL for the treatment of symptomatic small non obstructing lower ureteric calculi. SUBJECTS AND METHODS: This prospective non-randomised study was conducted simultaneously at two urological referral centres, included 280 patients with symptomatic small (4-10 mm lower ureteric calculi (situated below the sacroiliac joint, with good renal function on intravenous urography. Patients were offered both the treatment options. One hundred and sixty patients chose ureteroscopy, whereas 120 patients were treated by ESWL. Standard techniques of ureteroscopy and ESWL were employed. Patients were followed-up to assess the success rates and complications of the two procedures. RESULTS: Ureteroscopy achieved complete stone clearance in one session in 95% of patients. In six patients ureteroscopy had failed initially and was later accomplished in second session improving the success rate to 98.7%. Two patients had a proximal migration of calculus that needed ESWL. Of the 120 patients treated by ESWL, 90% achieved stone free status at three months. Ureteroscopy was needed for twelve patients (10% where ESWL failed to achieve stone clearance. There were no significant ESWL related complications. ESWL was administered on outpatient basis, while patients needed hospitalisation and anaesthesia for ureteroscopy. CONCLUSION: ESWL can be the primary mode of treatment for symptomatic small non-obstructing lower ureteric calculi as it is minimally invasive and safe. Ureteroscopy can be offered to patients who demand immediate relief or when ESWL fails.

    1998-02-01

    Fission gas pressure (FGR) and cladding elongation (PCMI) data of four high burnup PWR fuel rods with different grain size (8.5 and 22.1 μm) have been analysed and compared in the IFA-534.13 experiment. The fission gas release is low for both fuel types. During the first part of the irradiation there is no significant difference between the normal grain size fuel and the large grain size fuel. During the second part of the experiment , the FGR appears to be higher in the large grain size fuel. However, this result should be taken with some reservation since the bellows pressure transducer showed signs of irregular behaviour during this period. The FGR at end-of-life in the large grain size fuel is #approx=#2.1 %. The FGR at end-of-life in the normal grain size fuel is #approx=#1.5 %. The degree of PCMI is higher in the large grain size fuel during the first part of the irradiation. During the second period the difference is very small. The point of interaction for PCMI during power ramps has shifted to lower power between beginning and end of irradiation. The two fuel types exhibit very similar behaviour during power ramps. There is no clear indication of relaxation during the irradiation. (author)

    This was a phase I-II nonrandomized study that explored the toxicity and response of fractionated half-body irradiation (F-HBI) in patients with multiple symptomatic osseous metastases. The patients had no premedication and received 10 Gy in 5 fractions with a dose rate of 15 cGy/min. At the Cancer Institute Hospital, 9 patients were treated by this technique (1 upper and lower F-HBI, 6 upper F-HBI, 2 lower F-HBI). All patients were female and had adenocarcinomas (8 breast and 1 lung). Adverse effects were myelosuppression, vomiting and partial alopecia. But hematologic toxicity was treated with blood transfusion or G-CSF. All toxicity was transient, and no pneumonitis nor radiation-related deaths occurred. When given as palliation, F-HBI was found to relieve pain in 80% of the patients. In 10% of the patients the pain relief was complete. The mean time to achieve pain relief in responders after F-HBI was 9 days. The pain relief was long-lasting and continued without need of reirradiation for 40% of the remaining patient's life. This treatment modality appears to be well tolerated and effective in patients with multiple symptomatic osseous metastases. The optimal indications, dose and fractionation for F-HBI should be further explored in randomized trials. (author).

  7. Factors that influence therapeutic outcomes in symptomatic gastroesophageal reflux disease.

    LENUS (Irish Health Repository)

    Quigley, Eamonn M M

    2012-02-03

    The term "symptomatic gastroesophageal reflux disease" (GERD) refers to those patients who present with the typical GERD symptoms of heartburn and regurgitation, yet do not have endoscopic evidence of esophagitis. The primary goals of managing symptomatic GERD are to control symptoms and improve quality of life. A clinical assessment of the GERD patient can identify important clinical features, such as atypical and extraesophageal symptoms for which acid-suppressive agents tend to be less effective. Performing an endoscopy can further identify the patient as having nonerosive reflux disease, erosive esophagitis, or Barrett\\'s esophagus-diagnoses which can help determine treatment but may not prove predictive of therapeutic response. Determining acid exposure through pH testing can predict therapeutic response, with those revealing an abnormal acid exposure time being more responsive to acid-suppressive therapy. However, the performance of an endoscopy and pH testing on each patient is clearly not practical. Whereas the natural history of symptomatic GERD is still largely undefined, acid-suppressive therapy appears to be the best approach available for both the short-term and long-term management of this disease.

    To investigate the magnetic resonance (MR) enhancement patterns of symptomatic osteoporotic vertebral compression fracture (VCF) according to the fracture age, based on the successful single-level percutaneous vertebroplasty (PVP) cases. The study included 135 patients who underwent contrast-enhanced MR imaging and successful PVP from 2005 to 2010 due to a single- level osteoporotic VCF. Two radiologists blinded to the fracture age evaluated the MR enhancement patterns in consensus. The MR enhancement patterns were classified according to the enhancing proportion to the vertebral height and the presence or extent of a non-enhancing cleft within the enhancing area on sagittal plane. The Fisher' exact test, Kruskal-Wallis test and Mann-Whitney U test were performed to assess the differences in the MR enhancement patterns according to the fracture age. Symptomatic VCFs show variable MR enhancement patterns in all fracture ages. A diffuse enhancing area can be seen in not only the hyperacute and acute VCFs but also the chronic symptomatic VCFs. Symptomatic VCFs having a segmental enhancing area were all included in the hyperacute or acute stage. Most symptomatic osteoporotic VCFs had a non-enhancing cleft in the enhanced vertebral body (128/135, 94.8%). There was no statistical difference of the enhancement pattern according to the fracture age. Symptomatic VCFs show variable MR enhancement patterns in all fracture ages. The most common pattern is a non-enhancing cleft within a diffuse enhanced vertebra.

    BACKGROUND--Autonomic neuropathy provides a mechanism for the absence of symptoms in silent myocardial ischaemia, but characterisation of the type of neuropathy is lacking. AIM--To characterise and compare autonomic nerve function in patients with silent and symptomatic myocardial ischaemia. METHODS AND RESULTS--The Valsalva manoeuvre, heart rate variation (HRV) in response to deep breathing and standing, lower body negative pressure, isometric handgrip, and the cold pressor test were performed by patients with silent (n = 25) and symptomatic (n = 25) ambulatory ischaemia and by controls (n = 21). No difference in parasympathetic efferent function between patients with silent and symptomatic ischaemia was recorded, but both had significantly less HRV in response to standing than the controls (p < 0.005 for silent and p < 0.01 for symptomatic). Patients with silent ischaemia showed an increased propensity for peripheral vasodilatation compared with symptomatic patients (p < 0.02) and controls (p < 0.04). Impaired sympathetic function was found in patients with pure silent ischaemia (n = 4) compared with the remaining patients with silent ischaemia whose pain pathways were presumed to be intact. CONCLUSIONS--Patients with silent ischaemia and pain pathways presumed to be intact have an enhanced peripheral vasodilator response, and if this applied to the coronary vasculature it could provide a mechanism for limiting ischaemia to below the pain threshold. Patients with pure silent ischaemia have evidence of sympathetic autonomic dysfunction. Images PMID:8297687

    Women with symptomatic uterine fibroids can report a myriad of symptoms, including pain, bleeding, infertility, and psychosocial sequelae. Optimizing fibroid research requires the ability to enroll populations of women with image-confirmed symptomatic uterine fibroids. Our objective was to develop an electronic health record-based algorithm to identify women with symptomatic uterine fibroids for a comparative effectiveness study of medical or surgical treatments on quality-of-life measures. Using an iterative process and text-mining techniques, an effective computable phenotype algorithm, composed of demographics, and clinical and laboratory characteristics, was developed with reasonable performance. Such algorithms provide a feasible, efficient way to identify populations of women with symptomatic uterine fibroids for the conduct of large traditional or pragmatic trials and observational comparative effectiveness studies. Symptomatic uterine fibroids, due to menorrhagia, pelvic pain, bulk symptoms, or infertility, are a source of substantial morbidity for reproductive-age women. Comparing Treatment Options for Uterine Fibroids is a multisite registry study to compare the effectiveness of hormonal or surgical fibroid treatments on women's perceptions of their quality of life. Electronic health record-based algorithms are able to identify large numbers of women with fibroids, but additional work is needed to develop electronic health record algorithms that can identify women with symptomatic fibroids to optimize fibroid research. We sought to develop an efficient electronic health record-based algorithm that can identify women with symptomatic uterine fibroids in a large health care system for recruitment into large-scale observational and interventional research in fibroid management. We developed and assessed the accuracy of 3 algorithms to identify patients with symptomatic fibroids using an iterative approach. The data source was the Carolina Data Warehouse for

    IFA-S36 is irradiated with the main objective of extending the database on the performance of UO{sub 2}Gd{sub 2}O{sub 2} fuel (with 8% absorbing gadolinia isotopes) compared with commercial UO{sub 2}. The rig carries 6 rods in the lower cluster (including three Gd-doped fuel rods) and 3 rods in the upper cluster (one rod with Gd-doped fuel). The rods are instrumented with expansion thermometers (ETs), fuel and cladding elongation detectors (EFs and ECs) and pressure transducers (PFs). Repeated calorimetric power measurements, physics calculations by the HELIOS code and gamma scans of selected rods in both clusters enabled the power and burnup determination to be qualified and corrected. The data suggest that as of May 2004 the power ratings in both fuels are much alike and burnups are about 30 and 34 MW/kgUO{sub 2} in the Gd-doped and ordinary UO{sub 2} rods respectively. Analysis of in-pile measurements compared with calculations shows that neutron absorption affects fuel temperature, power and burnup radial distributions in Gd-doped fuel at BOL compared with UO{sub 2} fuel. Sensitivity analyses performed with the HELIOS and FTEMP3 codes show that fuel centreline temperature in Gd-doped fuel is influenced by radial power depression, depletion of fissile materials and absorbing Gd isotopes as well as thermal conductivity of the fuel matrix and its degradation during irradiation. Analysis of the fuel dimension changes revealed densification only in the UO{sub 2} fuel whereas fuel elongation measurements in the Gd-doped fuel rods indicated essentially constant swelling with burnup. At burnups above 5 MWd/kgUO{sub 2} the swelling rate was about 0.5-O.fi % DELTAV/V per 10 MWd/kgUO{sub 2} for both fuel types. Internal pressure measured in the Gd-doped rod at BOL showed slight fuel densification and possibly He gas absorption, whereas derived swelling rate was somewhat Iarger than values obtained from the fuel elongation measurements.

    Full Text Available Multiple sclerosis (MS is the commonest cause of disability in young adults. While there is increasing choice and better treatments available for delaying disease progression, there are still, very few, effective symptomatic treatments. For many patients such as those with primary progressive MS (PPMS and those that inevitably become secondary progressive, symptom management is the only treatment available. MS related symptoms are complex, interrelated, and can be interdependent. It requires good understanding of the condition, a holistic multidisciplinary approach, and above all, patient education and empowerment.

    2012-10-01

    Full Text Available Abstract Background Between 8% and 22% of female carriers of DMD mutations exhibit clinical symptoms of variable severity. Development of symptoms in DMD mutation carriers without chromosomal rearrangements has been attributed to skewed X-chromosome inactivation (XCI favouring predominant expression of the DMD mutant allele. However the prognostic use of XCI analysis is controversial. We aimed to evaluate the correlation between X-chromosome inactivation and development of clinical symptoms in a series of symptomatic female carriers of dystrophinopathy. Methods We reviewed the clinical, pathological and genetic features of twenty-four symptomatic carriers covering a wide spectrum of clinical phenotypes. DMD gene analysis was performed using MLPA and whole gene sequencing in blood DNA and muscle cDNA. Blood and muscle DNA was used for X-chromosome inactivation (XCI analysis thought the AR methylation assay in symptomatic carriers and their female relatives, asymptomatic carriers as well as non-carrier females. Results Symptomatic carriers exhibited 49.2% more skewed XCI profiles than asymptomatic carriers. The extent of XCI skewing in blood tended to increase in line with the severity of muscle symptoms. Skewed XCI patterns were found in at least one first-degree female relative in 78.6% of symptomatic carrier families. No mutations altering XCI in the XIST gene promoter were found. Conclusions Skewed XCI is in many cases familial inherited. The extent of XCI skewing is related to phenotype severity. However, the assessment of XCI by means of the AR methylation assay has a poor prognostic value, probably because the methylation status of the AR gene in muscle may not reflect in all cases the methylation status of the DMD gene.

    To examine the frequency and risk factors for symptomatic avascular necrosis (AVN) in childhood-onset systemic lupus erythematosus (cSLE). A single-center, nested, matched, case-control design was used. There were 617 patients with cSLE followed at the Hospital for Sick Children (SickKids) Lupus Clinic between July 1982 and June 2013 included in the study. The AVN cohort consisted of 37 patients identified with clinical findings of symptomatic AVN and diagnosis was confirmed by 1 or more imaging modalities. Three controls were matched to each patient with AVN by date and age at diagnosis. Baseline clinical, laboratory, and treatment characteristics were compared between patients with AVN and controls by univariable analyses and if statistically significant, were included in a multivariable logistic regression model. A total of 37/617 patients (6%) developed symptomatic AVN in 91 joints during followup at SickKids. The mean duration to disease was 2.3 years. The hip was the most commonly involved joint (26/37, 70%). Compared with the matched non-AVN cohort, patients with AVN had a higher incidence of central nervous system (CNS) involvement and nephritis, required greater cumulative prednisone (PRED) from cSLE diagnosis to AVN, received a greater maximal daily PRED dose, and had more frequent use of pulse methylprednisolone therapy. Multivariable regression analysis confirmed major organ involvement (CNS disease and/or nephritis) and maximal daily PRED dose as significant predictors of symptomatic AVN development. Patients with cSLE with severe organ involvement including nephritis and CNS disease and higher maximal daily dose of PRED are more likely to develop symptomatic AVN.

    Full Text Available Purpose. The recurrence of CBD stone is still observed in a considerable number of patients. The study was to evaluate the risk factors for recurrence of symptomatic CBD stone in patients who underwent cholecystectomy after the removal of CBD stone. Methods. The medical records of patients who underwent removal of CBD stone with subsequent cholecystectomy were reviewed. The risk factors for the recurrence of symptomatic CBD stone were compared between the recurrence and the nonrecurrence group. Results. The mean follow-up period was 40.6 months. The recurrence of symptomatic CBD stones was defined as the detection of bile duct stones no sooner than 6 months after complete clearance of CBD stones, based on symptoms or signs of biliary complication. 144 patients (68 males, 47.2% were finally enrolled and their mean age was 59.8 (range: 26~86 years. The recurrence of CBD stone occurred in 15 patients (10.4%. The mean period until first recurrence was 25.9 months. The presence of type 1 or 2 periampullary diverticulum and multiple CBD stones were the independent risk factors. Conclusion. For the patients with type 1 or 2 periampullary diverticulum or multiple CBD stones, careful followup is needed for the risk in recurrence of symptomatic CBD stone.

    Full Text Available Titanium craniofacial hardware has become commonplace for reconstruction and bone flap fixation following craniotomy. Complications of titanium hardware include palpability, visibility, infection, exposure, pain, and hardware malfunction, which can necessitate hardware removal. We describe three patients who underwent craniofacial reconstruction following craniotomies for trauma with post-operative courses complicated by medically intractable facial pain. All three patients subsequently underwent removal of the symptomatic craniofacial titanium hardware and experienced rapid resolution of their painful parasthesias. Symptomatic plates were found in the region of the frontozygomatic suture or MacCarty keyhole, or in close proximity with the supraorbital nerve. Titanium plates, though relatively safe and low profile, can cause local nerve irritation or neuropathy. Surgeons should be cognizant of the potential complications of titanium craniofacial hardware and locations that are at higher risk for becoming symptomatic necessitating a second surgery for removal.

    The aim of this study was to assess the efficacy and safety following endoscopic management of Zenker's diverticulum (ZD) using a needle-knife technique. A systematic search of PubMed, Embase and Cochrane library databases was performed. All original studies reporting efficacy and safety of needle-knife technique for treatment of ZD were included. Pooled event rates across studies were expressed with summative statistics. Main outcomes, such as rates of immediate symptomatic response (ISR), adverse events and recurrence, were extracted, pooled and analyzed. Heterogeneity among studies was assessed using the R statistic. The random effects model was used and results were expressed with forest plots and summative statistics. Thirteen studies included 589 patients were enrolled. Pooled event rates for ISR, overall complication, bleeding and perforation were 88% (95% confidence interval [CI] 79-94%), 13% (95% CI 8-22%), 5% (95% CI 3-10%) and 7% (95% CI 4-12%), respectively. The pooled data demonstrated an overall recurrence rate of 14% (95% CI 9-21%). Diverticulum size of at least 4 cm and less than 4 cm demonstrated pooled adverse event rates of 17% (95% CI 10-27%) and 7% (95% CI 2-18%), respectively. When using diverticuloscope as an accessory, pooled ISR and adverse events rates were 84% (95% CI 58-95%) and 10% (95% CI 3-26%), respectively. Flexible endoscopic procedures using needle-knife offers a relatively safe and effective treatment of symptomatic ZD, especially for ZD of <4 cm in diameter. © 2018 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    To determine an association between sonographically determined contractility with the symptomatic or silent nature of gallstone. Adult gallstone patients without (group I) and with biliary symptoms (group II) were compared with age and gender-matched controls. Demographic data, body mass index, risk factors, size, number and mobility of gallstone, gallbladder wall thickness (GBWT), volume and Ejection Fraction (EF) were determined on ultrasound before and after a standardized fatty meal (BFM and AFM). Demographic data, risk factors and gallstone characteristics were analyzed by Pearson Chi-square test and the gallbladder characteristics were analyzed by One-way ANOVA and Post Hoc tests by multiple comparisons on SPSS 11 with significance p=0.05. The gallbladder contractility as measured by changes in wall thickness and volume changes BFM and AFM, and ejection fraction was similar in controls and asymptomatic cholelithiasis groups and significantly reduced in symptomatic patients (p<.001). Multiparity (p=0.002), female gender (p=0.018), age less than 50 years (0.05), impacted calculi (p=0.001), multiple calculi (<.001) and calculi 5 mm (p<0.001) were associated with pain. A sluggishly emptying gallbladder was more significantly associated with symptomatic cholelithiasis compared to controls and asymptomatic cholelithiasis state in this series. Consideration of age, gender, impaction of calculi, number and size of calculi is important in causing symptom state and management options. (author)

    An association between aggrecan gene variable number of tandem repeats polymorphism (VNTR) and symptomatic lumbar disc herniation (LDH) has been reported in Chinese Han of Northern China, and obesity had previously been suspected of causing severe LDH. However, the interaction between aggrecan VNTR and obesity in symptomatic LDH has not been well studied. To examine the interaction between aggrecan VNTR and obesity in the susceptibility of symptomatic LDH, 259 participants participated in this study and donated a blood sample. The disease group comprised 61 patients already diagnosed with symptomatic LDH. The control group consisted of 198 healthy blood donors without symptoms of LDH who were not diagnosed with LDH. The aggrecan gene VNTR region was analyzed using polymerase chain reaction. The data indicated that between the two groups, participants carrying one or two alleles ≤25 repeats who were non-obese people showed a 1.057-fold increase in risk for symptomatic LDH (p = 0.895, changing the number of repeat alleles to 25 repeats who were obese people showed an 1.061-fold higher risk (p = 0.885, adding obesity to the mix alone did not demonstrably increase the risk of LDH), while participants carrying one or two alleles ≤25 repeats who were obese people showed a 4.667-fold increase in risk for symptomatic LDH (p = 0.0003, adding obesity plus changing the repeat allele number significantly increased the risk of LDH by 4.667). Overall, the findings suggest an underlying interaction between aggrecan VNTR and obesity in symptomatic LDH.

    Breast cancer is the most common female malignancy worldwide. Pakistan has the highest incidence rate of breast cancer than any other Asian population. The purpose of the study was to evaluate the worth of sono-mammography in diagnosis of symptomatic breast diseases by comparing it with mammogram. Methods: In this cross-sectional validation study, 45 subjects with mean age of 45+-12.07 were included. Majority of the patients presented with complaint of breast lump. After complete history and clinical examination, all the patients had high resolution ultrasound of bilateral breasts and axilla followed by bilateral mammography. Histopathology was taken as gold standard in this study. The exclusion criteria were pregnancy and patients having direct clinical signs of breast malignancy. Results: Based on histopathology, out of 45 patients with breast symptoms, 12 patients had benign lesions, whereas 32 patients were diagnosed as the cases of breast cancers. Finally one patient did not have biopsy proven final diagnosis. Sensitivity and specificity of ultrasound were calculated to be 100% and 67% as compared to sensitivity and specificity of 90.6% and 91.7% for that of mammography. Conclusions: Ultrasound is a useful complementary tool to mammography in assessment of symptomatic breast diseases since it helps in characterization and localization of breast lesions seen on mammogram and it is not limited by dense breasts. Also it should be the considered as initial imaging technique for assessment of palpable breast lumps. (author)

    Chondromalacia patella is a distinct clinical entity of abnormal softening of the articular cartilage of the patella, which results in chronic retropatellar pain. Its aetiology is still unclear but the process is thought to be a due to trauma to superficial chondrocytes resulting in a proteolytic enzymic breakdown of the matrix. Our aim was to assess the effectiveness of autologous chondrocyte implantation on patients with a proven symptomatic retropatellar lesion who had at least one failed conventional marrow-stimulating therapy. We performed chondrocyte implantation on 48 patients: 25 received autologous chondrocyte implantation with a type I/III membrane (ACI-C) method (Geistlich Biomaterials, Wolhusen, Switzerland), and 23 received the Matrix-assisted Chondrocyte Implantation (MACI) technique (Genzyme, Kastrup, Denmark). Over a mean follow-up period of 40.3 months, there was a statistically significant improvement in subjective pain scoring using the visual analogue scale (VAS) and objective functional scores using the Modified Cincinnati Rating System (MCS) in both groups. Chondromalacia patellae lesions responded well to chondrocyte implantation. Better results occurred with MACI than with ACI-C. Excellent and good results were achieved in 40% of ACI-C patients and 57% of MACI patients, but success of chondrocyte implantation was greater with medial/odd-facet lesions. Given that the MACI procedure is technically easier and less time consuming, we consider it to be useful for treating patients with symptomatic chondral defects secondary to chondromalacia patellae.

    Carotid revascularization may be considered for severe stenosis, but its use for symptomatic mild stenosis (<50%) with vulnerable plaque or ulcer remains uncertain. The characteristics of patients with symptomatic mild stenosis who underwent revascularization are reviewed. The subjects of this study were 18 patients with symptomatic mild stenosis (<50%) on angiography from among 175 patients who underwent revascularization in our department. The plaques were evaluated by black-blood magnetic resonance imaging (BB-MRI) and ultrasonography (US) and classified into 2 types: type 1 (n = 15), a lesion with an ulcer or mobile plaque or thrombosis on angiography or US; and type 2 (n = 3), a lesion without any of the above. Fourteen patients underwent carotid endarterectomy (CEA), and 4 patients underwent carotid artery stenting. The stenosis on angiography was 27.2% ± 10.7 (5%-41%), and the area carotid artery stenosis rate on US was 69.8 ± 14.5% (44.5%-97%). The stenosis rate of these 2 methods was not at all correlated. In type 1 plaque that underwent CEA, 10 of 11 patients had vulnerable plaque by histopathology, and 1 patient had thrombus on the plaque by operative findings. In type 2 plaque that underwent CEA, all patients had vulnerable plaque by histopathology. During the follow-up period, none of the patients had restenosis or stroke. The findings of US and BB-MRI in patients with symptomatic mild stenosis (<50%) on angiography are important for determining treatment. If BB-MRI or US shows the findings of vulnerable plaque in mild stenosis, surgical treatment may be considered for these patients. Copyright © 2018 National Stroke Association.

    As prostate artery embolisation (PAE) becomes an established treatment for benign prostatic obstruction, factors predicting good symptomatic outcome remain unclear. Pre-embolisation prostate size as a predictor is controversial with a handful of papers coming to conflicting conclusions. We aimed to investigate if an association existed in our patient cohort between prostate size and clinical benefit, in addition to evaluating percentage volume reduction as a predictor of symptomatic outcome following PAE. Prospective follow-up of 86 PAE patients at a single institution between June 2012 and January 2016 was conducted (mean age 64.9 years, range 54-80 years). Multiple linear regression analysis was performed to assess strength of association between clinical improvement (change in IPSS) and other variables, of any statistical correlation, through Pearson's bivariate analysis. No major procedural complications were identified and clinical success was achieved in 72.1% (n = 62) at 12 months. Initial prostate size and percentage reduction were found to have a significant association with clinical improvement. Multiple linear regression analysis (r 2  = 0.48) demonstrated that percentage volume reduction at 3 months (r = 0.68, p < 0.001) had the strongest correlation with good symptomatic improvement at 12 months after adjusting for confounding factors. Both the initial prostate size and percentage volume reduction at 3 months predict good symptomatic outcome at 12 months. These findings therefore aid patient selection and counselling to achieve optimal outcomes for men undergoing prostate artery embolisation.

    Unilateral vocal fold paralysis (UVFP) is a complication associated with cardiothoracic procedures that presents clinically as dysphonia and/or dysphagia with or without aspiration. The literature lacks both data on recovery of mobility and consensus on best management. Herein, our goals are to 1) Identify cardiothoracic procedures associated with symptomatic UVFP at our institution; 2) Review timing and nature of laryngology diagnosis and management; 3) Report spontaneous recovery rate of vocal fold mobility. Retrospective case series at single tertiary referral center between 2002 and 2015. 141 patients were included who underwent laryngology interventions (micronized acellular dermis injection laryngoplasty and/or type 1 thyroplasty) to treat symptomatic UVFP diagnosed subsequent to cardiothoracic surgery. Pulmonary procedures were most often associated with UVFP (n=50/141; 35.5%). 87.2% had left-sided paralysis (n=123/141). Median time to diagnosis was 42days (x¯=114±348). Over time, UVFP was diagnosed progressively earlier after cardiothoracic surgery. 63.4% of patients (n=95/141) underwent injection laryngoplasty as their initial intervention with median time from diagnosis to injection of 11days (x¯=29.6±54). 41.1% (n=58/141) ultimately underwent type 1 thyroplasty at a median of 232.5days (x¯=367±510.2) after cardiothoracic surgery. 10.2% (n=9/88) of those with adequate follow-up recovered full vocal fold mobility. Many cardiothoracic procedures are associated with symptomatic UVFP, predominantly left-sided. Our data showed poor recovery of vocal fold mobility relative to other studies. Early diagnosis and potential surgical medialization is important in the care of these patients. Copyright © 2017 Elsevier Inc. All rights reserved.

    To perform high-resolution magnetic resonance imaging (HRMRI) and determine clinical features of patients with acute symptomatic middle cerebral artery (MCA) dissection. Thirteen patients with acute symptomatic MCA dissection underwent HRMRI within 3 days after initial clinical onset. They also underwent routine brain MR imaging. HRMRI examinations included time-of-flight MR angiography (MRA), T2-weighted, T1-weighted, proton-density-weighted, and three-dimensional magnetization-prepared rapid acquisition gradient-echo (MPRAGE) sequences. Conventional angiography and MRA were used as reference standard to establish the diagnosis of MCA dissection. The angiographic findings and HRMRI findings such as intimal flap, double lumen, and intramural hematoma were analyzed in this study. All patients presented cerebral ischemia (median National Institutes of Health Stroke Scale score = 4, range = 0-18). String sign was seen on MRA in seven patients. However, double lumen was seen in all patients on HRMRI by intimal flap. High signal lesion on MPRAGE sequences around the dissection lumen due to intramural hematoma was seen in three patients. HRMRI can be used to easily detect the wall structure of MCA such as the intimal flap and double lumen in patients with acute symptomatic MCA dissection. MPRAGE can detect hemorrhage in false lumen of MCA dissection.

    The pathogenesis and drug resistance of symptomatic CLL patients involves genetic changes associated with the CLL clone as well as changes within the microenvironment. To further understand these processes, we compared early stage CLL to symptomatic late stage using gene expression and serum cytokine profiling to gain insight of the genetic and microenvironment changes associated with the most severe form of the disease. Patients were classified into low stage (Rai stage 0/I/II) and high stage (Rai stage III/IV). Gene expression profiles were obtained on pretreatment samples using the HG-U133A 2.0 Affymetrix platform. A comparison of low versus high stage CLL revealed a set of 21 genes differentially expressed genes. 15 genes were up regulated in the high stage compared to low stage while 6 genes were down regulated. Analysis of GO molecular function revealed 9 of 21 genes were involved in transcription factor activity. Serum cytokine profiles showed six cytokines to be significantly different in high stage patients. Two chemokines, SDF-1/CXCL12 and uPAR known to be involved in stem cell mobilization and homing were increased in serum of high stage patients. This study has identified therapeutic targets for symptomatic CLL patients. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The relationship between on-treatment platelet reactivity and cerebral micro-embolic signals (MES) is unknown, and has not been previously simultaneously assessed in asymptomatic and symptomatic carotid stenosis patients. Consecutive eligible patients with ≥50% asymptomatic or recently symptomatic carotid stenosis (≤4weeks following TIA/ischaemic stroke) were recruited to this pilot study. Symptomatic patients were followed up to the 'late' phase (≥3months) following symptom onset or carotid intervention; longitudinal data were analysed from symptomatic patients with data available at both time-points. Platelet function/reactivity was assessed with the PFA-100® to measure collagen-ADP (C-ADP) and collagen-epinephrine (C-EPI) closure times in citrate-anticoagulated whole blood. Bilateral simultaneous 1-hour transcranial Doppler ultrasound (TCD) monitoring of the middle cerebral arteries was performed to classify patients as MES +ve or MES -ve. 31 patients with ≥50% asymptomatic and 46 with early symptomatic carotid stenosis or occlusion were included. 35 symptomatic patients were followed up to the late phase (23 following carotid intervention). Prevalence of 'high on-treatment platelet reactivity' (HTPR) on the C-EPI cartridge did not differ between asymptomatic and symptomatic patients overall, but was lower in 'symptomatic post-intervention' than asymptomatic patients on aspirin monotherapy (10% vs. 50%; p=0.03). The prevalence of HTPR on the C-EPI cartridge decreased between the early and late phases in symptomatic patients (63% vs. 34%; p=0.017), including those on aspirin monotherapy (p=0.016). There were no significant differences in HTPR status between asymptomatic vs. early or late symptomatic MES +ve or MES -ve patients. Carotid interventional treatment, presumably in combination with resolution of the acute phase response, may decrease the prevalence of HTPR in patients with recently symptomatic carotid stenosis over time.

    The primary purpose of this retrospective study was to evaluate the differences of bone tracer uptake (BTU) in symptomatic and asymptomatic knees after bilateral total knee arthroplasty (TKA) and identify typical BTU patterns with regards to TKA component position and alignment. A consecutive number of 37 patients after bilateral TKA were retrospectively included. The knees were grouped into symptomatic (group A) and asymptomatic (group B) knees. All patients underwent 99m-Tc-HDP-SPECT/CT. Coronal, rotational, and sagittal TKA component position was analysed in 3D reconstructed CT. BTU was anatomically localised and quantified using a validated standardized localization scheme. Maximum BTU values for each area were recorded and normalized values calculated. Signed log-rank test, chi-square test, paired t-tests, and Pearson correlations were used (p <0.05). Symptomatic TKAs were significantly more flexed and had a tendency to be more internally rotated when compared to asymptomatic ones (p < 0.05). In all regions, the mean BTU in asymptomatic knees was lower than in symptomatic knees. In both groups the highest mean BTU was found around the tibial stem (symptomatic 7.30; asymptomatic 6.30, p = 0.061) and at the tip of the tibial stem (symptomatic 5.49; asymptomatic 4.74, p = 0.062). Superior patellar regions showed higher BTU than inferior regions. The highest patellar BTU was found in the superior medial patella (symptomatic 4.99; asymptomatic 3.98, p = 0.048). The lowest BTU was found in the posterior femoral regions (flatsp, flatip, fmedsp, fmedip) (Table 3). Tibial and patellar areas showed twice as high mean BTUs than femoral areas (Fig. 3). A significant correlation of TKA component position and BTU was demonstrated. Distribution and intensity of BTU in SPECT/CT depends on TKA component position and alignment. In addition, typical BTU patterns in symptomatic and asymptomatic knees were identified. A profound knowledge of BTU pattern, TKA component position

    Dental instrumentation has long provided insight into the mechanism of musculo-skeletal function of the gnathic system. While large population studies associate dental arch displacement (DAD), especially laterally, with symptoms, mandibular condyle displacement (CD) resulting from DAD has not been targeted as possibly etiologic in the production of common muscle contraction headache (CMCH) and temporo-mandibular dysfunction (TMD). The objective was to evaluate the three-dimensional nature of DAD and CD between the seated condylar position (SCP) and the intercuspal position (ICP) and to compare results derived from large deprogrammed asymptomatic and symptomatic populations. A total of 1 192 sets of dental casts collected from asymptomatic and symptomatic populations were articulated in the SCP. The initial occlusal contact, DAD, and condylar displacement were evaluated for frequency, direction, and magnitude of displacement between the SCP and ICP. The data revealed significant displacement between the SCP and ICP of the condyles (displaced most frequently inferior (down) and posterior (distal)) and substantially increased frequency and magnitude of displacement of the dental arches (with posterior premature occlusal contacts, increased overjet, decreased overbite, midline differences, and occlusal classification changes) in symptomatic subjects. These discrepancies were statistically significant and clinically significant. The data support the concept of increased DAD and CD with dysfunction. Transverse condylar displacement, commonly presenting with dental cross bite, may be associated with CMCH and TMD. Displacement of the mandibular condyle may be an etiologic factor in CMCH and dysfunction of the temporo-mandibular joint. PMID:27357324

    The comparative WWER/PWR test in IFA-503.1 was commenced in July 1995 and successfully finished at the end of November 1998. The main objective of the test was generation of representative and comparative data of standard WWER-440 fuel fabricated at the 'MSZ' Electrostal (Russia) and PWR type fuel manufactured at IFE Kjeller (Norway). The test assembly comprised two clusters, each with 3 WWER rods and 3 PWR type rods. Eight rods with two types of fuel were instrumented with expansion thermometers, four rods were equipped with both fuel stack elongation detectors and pressure transducers. All sensors worked satisfactorily during the test. The average burnups achieved in the lower and upper clusters were around 25 and 20 MWd/kgUO{sub 2}, respectively. Some difference in densification of the two types of fuel was revealed during the first irradiation period. However, the fuel temperatures and commencement of fuel stack swelling were similar despite this fact. At the end of the test the rig was moved to a higher flux position in the HBWR core with the aim of promoting FGR and to compare the behaviour of the two types of fuel under higher power. Pressure measurements indicated a comparable low FGR (around 1 percent) in both types of rods. The centreline temperatures measured in the PWR rods were very close to the Halden FGR threshold whilst the WWER fuel temperatures were slightly lower. Despite the differences found in the behaviour of the two types of fuel during the test, the analysis of the in-pile data showed that these differences would not affect the fuel efficiency, at least, up to the burnup achieved in the test. It is supposed that these differences can be related to the fuel microstructure, in particular to the fuel grain and pore sizes (author) (ml)

    The comparative WWER/PWR test in IFA-503.1 was commenced in July 1995 and successfully finished at the end of November 1998. The main objective of the test was generation of representative and comparative data of standard WWER-440 fuel fabricated at the 'MSZ' Electrostal (Russia) and PWR type fuel manufactured at IFE Kjeller (Norway). The test assembly comprised two clusters, each with 3 WWER rods and 3 PWR type rods. Eight rods with two types of fuel were instrumented with expansion thermometers, four rods were equipped with both fuel stack elongation detectors and pressure transducers. All sensors worked satisfactorily during the test. The average burnups achieved in the lower and upper clusters were around 25 and 20 MWd/kgUO{sub 2}, respectively. Some difference in densification of the two types of fuel was revealed during the first irradiation period. However, the fuel temperatures and commencement of fuel stack swelling were similar despite this fact. At the end of the test the rig was moved to a higher flux position in the HBWR core with the aim of promoting FGR and to compare the behaviour of the two types of fuel under higher power. Pressure measurements indicated a comparable low FGR (around 1 percent) in both types of rods. The centreline temperatures measured in the PWR rods were very close to the Halden FGR threshold whilst the WWER fuel temperatures were slightly lower. Despite the differences found in the behaviour of the two types of fuel during the test, the analysis of the in-pile data showed that these differences would not affect the fuel efficiency, at least, up to the burnup achieved in the test. It is supposed that these differences can be related to the fuel microstructure, in particular to the fuel grain and pore sizes (author) (ml)

    To assess the work impact of symptomatic uterine fibroids (UFs). A cohort study compared 58 employed women with symptomatic UFs to 56 healthy controls. Data sources included a self-administered mail questionnaire and medical charts. At-work performance limitations and productivity loss were measured with the Work Limitations Questionnaire. Univariate and multivariate case-control group differences were tested. Based on adjusted mean scores, the UF group had significantly more at-work limitations and productivity loss than controls, while absence rates were similar. The UF group's performance was impaired 18% of the time on average versus 8% for controls (P-values, 0.005-0.040). At-work limitations were explained by depression symptoms, Non-White race/ethnicity, and poorer health-related quality of life. Fibroids and related symptoms impose a burden on the working lives' of women, their employers, and the economy.

    Introduction: Open cholecystectomy (OC) has gradually been superseded by laparoscopic cholecystectomy (LC) for the treatment of cholelithiasis. Laparoscopic cholecystectomy is associated with fewer complications than open cholecystectomy when performed in experienced hands. The study was conducted to compare the two techniques for management of symptomatic gall stones. Objective: Our objective was to compare the management outcomes of laparoscopic cholecystectomy with those of open holecystectomy in the treatment of symptomatic cholelithiasis. Study Design: Quasi experimental study. Settings: It was carried out at Surgical Unit - I of Holy Family Hospital, Rawalpindi. Subjects and Methods: Eighty consecutive patients with symptomatic cholelithiasis confirmed on ultrasonography from September 2007 to March 2008 were included in the study. They were randomly allocated to LC or OC and were eventually operated. Results: Mean operating time of LC was 64 minutes (30-90) (SD=13.4) where as in OC it was 37.12 minutes (25-70) (SD-9.6). Return of bowel sounds postoperatively was within 12 hours (9-18) (SD=3.25) in LC while it was 16 hours (9-30) in OC group (SD=4.75). Postoperative hospital stay was 1.5 days mean (1-4 days) (SD=0.71). In LC while it was 2.9 days (2-5) in OC group (SD=0.84). The duration of injectable analgesia requirement was 1.3 days (1-3) (SD=0.51) and 1.8 days (1-3) (SD=0.7) in LC and OC patients respectively. The gall bladder perforation was 22.5% in OC and 15% in LC. The common bile duct injury occurred in 2% of patients with LC while none with OC. The conversion rate was 5%. Conclusion: Laparoscopic cholecystectomy is safe treatment of cholelithiasis with short duration of postoperative hospital stay, lesser post operative pain, early return of normal bowel activity as compared to the open cholecystectomy.

    The aim of this work is to use quantitative magnetic resonance imaging (MRI) to identify patients at risk for symptomatic osteoarthritis (OA) progression. We hypothesized that classification of signal variation on T2 maps might predict symptomatic OA progression. Patients were selected from the Osteoarthritis Initiative (OAI), a prospective cohort. Two groups were identified: a symptomatic OA progression group and a control group. At baseline, both groups were asymptomatic (Western Ontario and McMaster Universities Arthritis [WOMAC] pain score total <10) with no radiographic evidence of OA (Kellgren-Lawrence [KL] score ≤ 1). The OA progression group (n = 103) had a change in total WOMAC score greater than 10 by the 3-year follow-up. The control group (n = 79) remained asymptomatic, with a change in total WOMAC score less than 10 at the 3-year follow-up. A classifier was designed to predict OA progression in an independent population based on T2 map cartilage signal variation. The classifier was designed using a nearest neighbor classification based on a Gaussian Mixture Model log-likelihood fit of T2 map cartilage voxel intensities. The use of T2 map signal variation to predict symptomatic OA progression in asymptomatic individuals achieved a specificity of 89.3 %, a sensitivity of 77.2 %, and an overall accuracy rate of 84.2 %. T2 map signal variation can predict symptomatic knee OA progression in asymptomatic individuals, serving as a possible early OA imaging biomarker. (orig.)

    To estimate the prevalence and risk factors of symptomatic dry eye disease (DED) among undergraduate students in a Ghanaian university. This cross-sectional study included 700 undergraduate students of the University of Cape Coast, aged 18 to 34 years. Participants completed questionnaires delivered directly to randomly and systematically selected subjects to detect symptomatic dry eye and its predictive factors. Symptomatic dry eye was defined as any reported symptom on the Standard Patient Evaluation Eye Dryness (SPEED) questionnaire reported as often or constant or if any symptom on the Ocular Surface Disease Index (OSDI) was reported as most of the time or all of the time. Furthermore, OSDI ≥13 and SPEED ≥6 were used to defined symptomatic dry eye and prevalence were also estimated with these criteria as secondary measures. Current symptoms of dry eye and possible risk factors such as age, gender, current alcohol drinking, use of oral contraceptives, use of computer more than an hour daily, environmental conditions, allergies, and self-medication with over-the-counter eye drops were the main outcome measures. We used logistic regression analysis to examine the associations between dry eye and its predictive factors. Of the 700 participants, 650 completed the questionnaire. The prevalence of symptomatic dry eye was 44.3% (95% confidence interval [CI], 40.6%-48.2%). There was a significant association between symptomatic dry eye and discomfort with eyes in windy conditions (χ=110.1; df=4; Peye drops (OR 4.20; 95% CI, 2.61-6.74; Pdry eye. Sex was predictive in univariate analysis but was not significantly associated in multivariate analysis. The prevalence of symptomatic dry eye among undergraduate students in Ghana is high and it is associated with self-medication with over-the-counter eye drops, allergies, use of oral contraceptive, windy conditions, very low humid areas, air-conditioned rooms, and sex. Relevant input directed against modifiable risks

    Gastroesophageal reflux (GER) is very common in pre-term infants. The diagnosis based on symptoms is always questionable. The incidence of GER in symptomatic babies varies from 22% to 85%, but literature regarding the incidence of reflux in asymptomatic pre-term infants is lacking. We used radionuclide scintigraphy to evaluate the incidence of GER in symptomatic as well as asymptomatic pre-term neonates and to assess whether symptoms have any relation with positive scintigraphy. We studied 106 pre-term infants (52 symptomatic, 54 asymptomatic) of less than 34 weeks of gestation, who fulfilled the eligibility criteria. Babies were considered symptomatic in the presence of vomiting, regurgitation, apnea, de-saturations, unexplained bradycardia and recurrent lung collapses. Radionuclide scintigraphy was conducted at post-conceptional age of 32-34 weeks when they were clinically stable for 72 h. Feeding was avoided for 2 h preceding the study. {sup 99m}Tc sulphur colloid was administered in a dose of 1.85 MBq (0.05 mCi) in 1 ml, followed by milk (full feed) through an orogastric tube, prior to imaging under a gamma camera. Reflux was graded as low or high, and reflux episodes during the study were counted. The incidence of GER in the symptomatic group was 71.2% and in asymptomatic babies 61.1% (p=0.275). High-grade reflux was more common (71.4%) than low-grade (28.6%) in both groups (p=0.449). Mean number of reflux episodes in 20 min was 4.4{+-}2.4 in symptomatic babies and 4.9 {+-}2.2 in asymptomatic babies (p=0.321). Babies with positive scintigraphy were similar in birth weight, gestation, time to achieve full feeds, weight and age at discharge to those with negative scintigraphy. GER is common in pre-term infants of less than 34 weeks gestation. The incidence of positive scintigraphy and grade of reflux is not significantly different in symptomatic vs. asymptomatic babies. Though radionuclide scintigraphy is a simple, quick and non-invasive investigation in

    Medical expulsive therapy represents an effective adjunctive treatment for nonpregnant patients with symptomatic urolithiasis. Tamsulosin is classified by the FDA (Food and Drug Administration) as a category B medication. However, to our knowledge no published data exist for human pregnancy. We explored the safety and efficacy of tamsulosin therapy for symptomatic urolithiasis occurring during pregnancy. We retrospectively identified patients treated with tamsulosin for stone disease during pregnancy at the Mayo Clinic during 2000 to 2014. This medical expulsive therapy cohort was matched 2:1 to pregnant women with symptomatic urolithiasis during pregnancy who did not receive medical expulsive therapy. Groups were compared using linear mixed models for continuous variables and exact conditional logistic regression models for nominal variables to take into account correlation due to matching. A total of 27 patients receiving medical expulsive therapy comprised the study cohort. Median duration of antepartum tamsulosin exposure was 3 days (range 1 to 110), occurring during the first, second and third trimester in 3 (11%), 11 (40.7%) and 18 (67%) patients, respectively. Mean gestational age at delivery was 38.1 weeks (SD 2.4) and 6 (22%) infants were born preterm. All infant birthweights were considered appropriate for gestational age, and no cases of spontaneous abortion, intrauterine demise or neonatal congenital anomalies were encountered. Comparison between the medical expulsive therapy and control groups demonstrated no significant differences in maternal or infant outcomes for any of the examined variables. Tamsulosin medical expulsive therapy does not appear to be associated with adverse maternal or fetal outcomes and may be considered as adjunctive therapy for urolithiasis during pregnancy.

    Full Text Available Introduction: Gastric volvulus is a surgical condition that should be recognised promptly to prevent life-threatening gastric ischaemia and perforation in acute setting. There are two peak age group of incidence with children less than one year old and at fifth decade.1 The mortality rates for acute gastric volvulus remain high with reported range from 30% to 50% signifying the need of early diagnosis and treatment.2 These case series reported modified minimal invasive approach for symptomatic chronic gastric volvulus in a tertiary upper gastrointestinal unit in Singapore. Methods: Retrospective case series reviewed in single centre from 1st May 2016 to 1st May 2017 of clinical outcomes of modified minimally invasive approach and de-rotation of symptomatic chronic gastric volvulus. Results: Three symptomatic patients with evidence of gastric volvulus on CT-scan underwent minimally invasive repair with the aids of GastriSail™ Gastric positioning system. GastriSail™ was used for gastric volvulus de-rotation prior to repair definitely. Two patients had fundoplication done and one patient had gastropexy performed successfully. All patients started on blended diet post-operative day 1 and discharged well. Patient remained asymptomatic and nil recurrence at 3 months follow-up post-operation. Conclusion: Based on our experience, we advocate modified minimally invasive repair of chronic gastric volvulus as an alternative to traditional open surgical technique with acceptable good clinical outcomes.

    Background West Nile virus (WNV) infection is mostly asymptomatic but 20% of subjects report WNV fever and 1% of patients experience neurological diseases with higher rates in elderly and immunosuppressed persons. With no treatment and no vaccine to prevent the development of symptomatic infections, it is essential to understand prognostic factors influencing symptomatic disease outcome. Host genetic background has been linked to the development of WNV neuroinvasive disease. The present study investigates the association between the ABO and Rh(D) blood group status and WNV disease outcome. Study Design and Methods The distribution of blood groups was investigated within a cohort of 374 WNV+ blood donors including 244 asymptomatic (AS) and 130 symptomatic (S) WNV+ blood donors. Logistic regression analyses were used to examine associations between A, B, O and Rh(D) blood groups and WNV clinical disease outcome. Results Symptomatic WNV+ donors exhibited increased frequencies of blood group A (S 47.6% AS 36.8%, P=0.04, OR [95%CI] 1.56 [1.01–2.40]) and Rh(D)-negative individuals (S 21.5% AS 13.1%, P=0.03, OR [95%CI] 1.82 [1.04–3.18]). Conclusion The findings suggest a genetic susceptibility placing blood group A and Rh(D)-negative individuals at risk for the development of symptomatic disease outcome after WNV infection.

    Background Recent evidence suggests that less than one-quarter of patients with symptomatic nosocomial Clostridium difficile infections (CDI) are linked to other in-patients. However, this evidence was limited to one geographic area. We aimed to investigate the level of symptomatic CDI transmission in hospitals located across England from 2008 to 2012. Methods A generalized additive mixed-effects Poisson model was fitted to English hospital-surveillance data. After adjusting for seasonal fluctuations and between-hospital variation in reported CDI over time, possible clustering (transmission between symptomatic in-patients) of CDI cases was identified. We hypothesised that a temporal proximity would be reflected in the degree of correlation between in-hospital CDI cases per week. This correlation was modelled through a latent autoregressive structure of order 1 (AR(1)). Findings Forty-six hospitals (33 general, seven specialist, and six teaching hospitals) located in all English regions met our criteria. In total, 12,717 CDI cases were identified; seventy-five per cent of these occurred >48 hours after admission. There were slight increases in reports during winter months. We found a low, but statistically significant, correlation between successive weekly CDI case incidences (phi = 0.029, 95%CI: 0.009–0.049). This correlation was five times stronger in a subgroup analysis restricted to teaching hospitals (phi = 0.104, 95%CI: 0.048–0.159). Conclusions The results suggest that symptomatic patient-to-patient transmission has been a source of CDI-acquisition in English hospitals in recent years, and that this might be a more important transmission route in teaching hospitals. Nonetheless, the weak correlation indicates that, in line with recent evidence, symptomatic cases might not be the primary source of nosocomial CDI in England. PMID:24932484

    Objective To investigate the risk factors of symptomatic bradyarrhythmias in relation to β-blockers use. Methods A hospital-based case-control study [228 patients: 108 with symptomatic bradyarrhythmias (cases) and 120 controls] was conducted in Sultanah Aminah Hospital, Malaysia between January 2011 and January 2014. Results The mean age was 61.1 ± 13.3 years with a majority of men (68.9%). Cases were likely than control to be older, hypertensive, lower body mass index and concomitant use of rate-controlling drugs (such as digoxin, verapamil, diltiazem, ivabradine or amiodarone). Significantly higher level of serum potassium, urea, creatinine and lower level of estimated glomerular filtration rate (eGFR) were observed among cases as compared to controls. On univariate analysis among patients on β-blockers, older age (crude OR: 1.07; 95% CI: 1.03–1.11, P = 0.000), hypertension (crude OR: 5.6; 95% CI: 1.51–20.72, P = 0.010), lower sodium (crude OR: 0.04; 95% CI: 0.81–0.99, P = 0.036), higher potassium (crude OR: 2.36; 95% CI: 1.31–4.26, P = 0.004) and higher urea (crude OR: 1.23; 95% CI: 1.11–1.38, P = 0.000) were associated with increased risk of symptomatic bradyarrhythmias; eGFR was inversely and significantly associated with symptomatic bradyarrhythmias in both ‘β-blockers’ (crude OR: 0.97; 95% CI: 0.96–0.98, P = 0.000) and ‘non-β-blockers’ (crude OR: 0.99; 95% CI: 0.97–0.99, P = 0.023) arms. However, eGFR was not significantly associated with symptomatic bradyarrhythmias in the final model of both ‘β-blockers’ (adjusted OR: 0.98; 95% CI: 0.96–0.98, P = 0.103) and ‘non-β-blockers’ (adjusted OR: 0.99; 95% CI: 0.97–1.01, P = 0.328) arms. Importantly, older age was a significant predictor of symptomatic bradyarrhythmias in the ‘β-blockers’ as compared to the ‘non-β-blockers’ arms (adjusted OR: 1.09; 95% CI: 1.03–1.15, P = 0.003 vs. adjusted OR: 1.03; 95% CI: 0.98–1.09, P = 0.232, respectively).

    Moderate-severe obstructive sleep apnoea (OSA) has been associated with several pro-atherogenic mechanisms and increased cardiovascular risk, but it is not known if minimally symptomatic OSA has similar effects. Circulating cell-derived microparticles have been shown to have pro-inflammatory, pro-coagulant and endothelial function-impairing effects, as well as to predict subclinical atherosclerosis and cardiovascular risk. In 57 patients with minimally symptomatic OSA, and 15 closely matched control subjects without OSA, AnnexinV-positive, platelet-, leukocyte- and endothelial cell-derived microparticles were measured by flow cytometry. In patients with OSA, median (interquartile range) levels of AnnexinV-positive microparticles were significantly elevated compared with control subjects: 2,586 (1,566-3,964) microL(-1) versus 1,206 (474-2,501) microL(-1), respectively. Levels of platelet-derived and leukocyte-derived microparticles were also significantly higher in patients with OSA (2,267 (1,102-3,592) microL(-1) and 20 (14-31) microL(-1), respectively) compared with control subjects (925 (328-2,068) microL(-1) and 15 (5-23) microL(-1), respectively). Endothelial cell-derived microparticle levels were similar in patients with OSA compared with control subjects (13 (8-25) microL(-1) versus 11 (6-17) microL(-1)). In patients with minimally symptomatic obstructive sleep apnoea, levels of AnnexinV-positive, platelet- and leukocyte-derived microparticles are elevated when compared with closely matched control subjects without obstructive sleep apnoea. These findings suggest that these patients may be at increased cardiovascular risk, despite being minimally symptomatic.

    Schnarr, J; Smaill, F

    2008-10-01

    Symptomatic and asymptomatic bacteriuria is common in pregnant women. A history of previous urinary tract infections and low socioeconomic status are risk factors for bacteriuria in pregnancy. Escherichia coli is the most common aetiologic agent in both symptomatic and asymptomatic infection and quantitative culture is the gold standard for diagnosis. Treatment of asymptomatic bacteriuria has been shown to reduce the rate of pyelonephritis in pregnancy and therefore screening for and treatment of asymptomatic bacteriuria has become a standard of obstetrical care. Antibiotic treatment of asymptomatic bacteriuria is associated with a decrease in the incidence of low birth weight, but the methodological quality of the studies limits the strength of the conclusions that can be drawn. Debate exists in the literature as to whether treated pyelonephritis is associated with adverse fetal outcomes. There is no clear consensus in the literature on antibiotic choice or duration of therapy for infection. With increasing antibiotic resistance, consideration of local resistance rates is necessary when choosing therapy.

    Gastroesophageal reflux (GER) is very common in pre-term infants. The diagnosis based on symptoms is always questionable. The incidence of GER in symptomatic babies varies from 22% to 85%, but literature regarding the incidence of reflux in asymptomatic pre-term infants is lacking. We used radionuclide scintigraphy to evaluate the incidence of GER in symptomatic as well as asymptomatic pre-term neonates and to assess whether symptoms have any relation with positive scintigraphy. We studied 106 pre-term infants (52 symptomatic, 54 asymptomatic) of less than 34 weeks of gestation, who fulfilled the eligibility criteria. Babies were considered symptomatic in the presence of vomiting, regurgitation, apnea, de-saturations, unexplained bradycardia and recurrent lung collapses. Radionuclide scintigraphy was conducted at post-conceptional age of 32-34 weeks when they were clinically stable for 72 h. Feeding was avoided for 2 h preceding the study. 99m Tc sulphur colloid was administered in a dose of 1.85 MBq (0.05 mCi) in 1 ml, followed by milk (full feed) through an orogastric tube, prior to imaging under a gamma camera. Reflux was graded as low or high, and reflux episodes during the study were counted. The incidence of GER in the symptomatic group was 71.2% and in asymptomatic babies 61.1% (p=0.275). High-grade reflux was more common (71.4%) than low-grade (28.6%) in both groups (p=0.449). Mean number of reflux episodes in 20 min was 4.4±2.4 in symptomatic babies and 4.9 ±2.2 in asymptomatic babies (p=0.321). Babies with positive scintigraphy were similar in birth weight, gestation, time to achieve full feeds, weight and age at discharge to those with negative scintigraphy. GER is common in pre-term infants of less than 34 weeks gestation. The incidence of positive scintigraphy and grade of reflux is not significantly different in symptomatic vs. asymptomatic babies. Though radionuclide scintigraphy is a simple, quick and non-invasive investigation in suspected cases

    This study aimed to evaluate antenatal risk factors associated with symptomatic congenital cytomegalovirus (CMV) disease, following in utero vertical infection. This study included a retrospective cohort of 155 neonates with congenital CMV infection, following primary maternal CMV infection during pregnancy, and were divided to symptomatic (n=95) and asymptomatic (n=60) newborns. Young maternal age (29.1±5.12 vs. 31.6±5.36 years, P=0.005), high risk occupation for viral exposure (20.0% vs. 11.7%, P=0.04), CMV IgG seroconversion at diagnosis (83.1% vs. 63.3%, P=0.005) and abnormal fetal MRI (11.6% vs. 0%, P=0.003) were found to be prognostic risk factors associated with symptomatic CMV disease of the newborn. Maternal febrile illness at diagnosis, IgG avidity, US findings and the timing of maternal infection were not associated with the occurrence of neonatal symptoms. Knowledge of the reported risk factors may assist in counseling parents with intra uterine CMV infection.

    To evaluate retrospectively whether symptomatic acromioclavicular joints can be differentiated from asymptomatic acromioclavicular joints on 3-T MR imaging. This study included 146 patients who underwent physical examination of acromioclavicular joints and 3-T MR imaging of the shoulder. Among them, 67 patients showing positive results on physical examination were assigned to the symptomatic group, whereas 79 showing negative results were assigned to the asymptomatic group. The following MR findings were compared between the symptomatic and asymptomatic groups: presence of osteophytes, articular surface irregularity, subchondral cysts, acromioclavicular joint fluid, subacromial fluid, subacromial bony spurs, joint capsular distension, bone edema, intraarticular enhancement, periarticular enhancement, superior and inferior joint capsular distension degree, and joint capsular thickness. The patients were subsequently divided into groups based on age (younger, older) and the method of MR arthrography (direct MR arthrography, indirect MR arthrography), and all the MR findings in each subgroup were reanalyzed. The meaningful cutoff value of each significant continuous variable was calculated using receiver operating characteristic analysis. The degree of superior capsular distension was the only significant MR finding of symptomatic acromioclavicular joints and its meaningful cutoff value was 2.1mm. After subgroup analyses, this variable was significant in the older age group and indirect MR arthrography group. On 3-T MR imaging, the degree of superior joint capsular distension might be a predictable MR finding in the diagnosis of symptomatic acromioclavicular joints. Copyright © 2012 Elsevier Ireland Ltd.

    Full Text Available Ectopic salivary gland tissue in sellar turcica is frequently observed in microscopic examination at autopsy. This tissue is considered clinically silent. Only 2 symptomatic cases have been previously reported. Here we report a 28-year-old woman presenting with galactorrhea and hyperprolactinemia. Magnetic resonance imaging revealed a 6×5-mm nodule in the posterior aspect of the pituitary gland. This nodule showed isointensity on T1- and T2-weighted images and less enhancement on post-contrast T1-weighted images. Transsphenoidal exploration revealed a cystic lesion within the pituitary gland, which consisted of a grayish gelatinous content. The pathologic examination confirmed the diagnosis of salivary gland rest.

    Hemorrhoids are the most common anorectal complaint, and approximately 10 to 20 percent of patients with symptomatic hemorrhoids require surgery. Symptoms of hemorrhoids, such as painless rectal bleeding, tissue protrusion and mucous discharge, vary. The traditional therapeutic strategies of medicine include surgical, as well as non-surgical, treatment. To alleviate symptoms caused by hemorrhoids, oral treatments, such as fiber, suppositories and Sitz baths have been applied to patients. Other non-surgical treatments, such as infrared photocoagulation, injection sclerotherapy and rubber band ligation have been used to fixate the hemorrhoid's cushion. If non-surgical treatment has no effect, surgical treatments, such as a hemorrhoidectomy, procedure for prolapsed hemorrhoids, and transanal hemorrhoidal dearterialization are used. PMID:22259741

    Biomechanical stresses play an important role in determining plaque stability. Quantification of these simulated stresses can be potentially used to assess plaque vulnerability and differentiate different patient groups. 54 asymptomatic and 45 acutely symptomatic patients underwent in vivo multicontrast magnetic resonance imaging (MRI) of the carotid arteries. Plaque geometry used for finite element analysis was derived from in vivo MRI at the sites of maximum and minimum plaque burden. In total, 198 slices were used for the computational simulations. A pre-shrink technique was used to refine the simulation. Maximum principle stress at the vulnerable plaque sites (id est (ie), critical stress) was extracted for the selected slices and a comparison was performed between the 2 groups. Critical stress in the slice with maximum plaque burden is significantly higher in acutely symptomatic patients as compared to asymptomatic patients (median, inter quartile range: 198.0 kPa (119.8-359.0 kPa) vs 138.4 kPa (83.8-242.6 kPa), P=0.04). No significant difference was found in the slice with minimum plaque burden between the 2 groups (196.7 kPa (133.3-282.7 kPa) vs 182.4 kPa (117.2-310.6 kPa), P=0.82). Acutely symptomatic carotid plaques have significantly high biomechanical stresses than asymptomatic plaques. This might be potentially useful for establishing a biomechanical risk stratification criteria based on plaque burden in future studies. (author)

    Current studies reporting on the risk of smoking and development of symptomatic diverticular disease have reported conflicting results. The aim of this study was to investigate the association between smoking and symptomatic diverticular disease. This is a cohort study : Information was derived from the Swedish Construction Workers Cohort 1971-1993. Patients were selected from construction workers in Sweden. The primary outcome measured was the development of symptomatic diverticular disease and complicated diverticular disease (abscess and perforation) as identified in the Swedish Hospital Discharge Register. Adjusted relative risks of symptomatic diverticular disease according to smoking status were estimated by using negative binomial regression analysis. In total, the study included 232,685 men and 14,592 women. During follow-up, 3891 men and 318 women had a diagnosis of later symptomatic diverticular disease. In men, heavy smokers (≥15 cigarettes a day) had a 1.6-fold increased risk of developing symptomatic diverticular disease compared with nonsmokers (adjusted relative risk, 1.56; 95% CI, 1.42-1.72). There was evidence of a dose-response relationship, because moderate and ex-smokers had a 1.4- and 1.2-fold increased risk compared with nonsmokers (adjusted relative risk, 1.39; 95% CI, 1.27-1.52 and adjusted relative risk, 1.14; 95% CI, 1.04-1.27). These relationships were similar in women, but the risk estimates were less precise owing to smaller numbers. Male ever-smokers had a 2.7-fold increased risk of developing complicated diverticular disease (perforation/abscess) compared with nonsmokers (adjusted relative risks, 2.73; 95% CI, 1.69-4.41). We were unable to account for other confounding variables such as comorbidity, prescription medication, or lifestyle factors. Smoking is associated with symptomatic diverticular disease in both men and women and with an increased risk of developing complicated diverticular disease.

    Newborn screening for urinary cytomegalovirus (CMV) and early introduction of antiviral treatment are expected to improve neurological outcomes in symptomatic congenital CMV-infected infants. This cohort study prospectively evaluated neurological outcomes in symptomatic congenital CMV-infected infants following the introduction of hospital-based newborn urinary CMV screening and antiviral treatment. Following institutional review board approval and written informed consent from their parents, newborns were prospectively screened from 2009 to 2014 for urinary CMV-DNA by PCR within 1 week after birth at Kobe University Hospital and affiliated hospitals. CMV-positive newborns were further examined at Kobe University Hospital, and those diagnosed as symptomatic were treated with valganciclovir for 6 weeks plus immunoglobulin. Clinical neurological outcomes were evaluated at age ⩾12 months and categorized by the presence and severity of neurologic sequelae. Urine samples of 6348 newborns were screened, with 32 (0.50%) positive for CMV. Of these, 16 were diagnosed with symptomatic infection and 12 received antiviral treatment. Four infants developed severe impairment (33%), three developed mild impairment (25%), and five developed normally (42%). This is the first Japanese report of neurological assessments in infants with symptomatic congenital CMV infection who received early diagnosis and antiviral treatment. Urinary screening, resulting in early diagnosis and treatment, may yield better neurological outcomes in symptomatic congenital CMV-infected infants.

  10. Subsyndromal symptomatic depression: a new concept.

    2000-01-01

    Although DSM-IV acknowledged the clinical significance of some subthreshold forms of unipolar depression, such as minor depression (MinD) and recurrent brief depression (RBD), clinicians continued to struggle with the concept of "subthreshold" depression. A substantial number of patients continued to present with depressive symptoms that still did not satisfy any DSM-IV diagnosis. Generally, these patients failed to complain of anhedonia and depressed mood, a criterion that DSM-IV mandates for any diagnosis of depression. Therefore, researchers reexamined the question of whether this cluster of depressive symptoms, in the absence of anhedonia and depressed mood, was clinically significant. Some researchers labeled this cluster of symptoms, "subsyndromal symptomatic depression" (SSD). Specifically, SSD is defined as a depressive state having two or more symptoms of depression of the same quality as in major depression (MD), excluding depressed mood and anhedonia. The symptoms must be present for more than 2 weeks and be associated with social dysfunction. Using Medline Search, the authors reviewed the literature on the epidemiology, demographics, clinical characteristics, and psychosocial impairment of SSD. SSD is found to be comparable in demographics and clinical characteristics to MD, MinD, and dysthymia. SSD is also associated with significant psychosocial dysfunction as compared with healthy subjects. Further; it has significant risk for suicide and future MD. Few studies have been conducted on the treatment of SSD. The high prevalence of SSD, the significant psychosocial impairment associated with it, and the chronicity of its course make subsyndromal symptomatic depression a matter for serious consideration by clinicians and researchers.

    Bone matastases are one of the most common and serious conditions requiring radiotherapy, but there is still a considerable lack of agreement on optimal radiation schedule. We analyzed patients with symptomatic osseous matastases from lung (72 patients) and breast (63 patients) carcinoma treated by palliative radiotherapy between 1983 and 1992. In this series, the incidences of symptomatic bone metastases appearing within 2 years after the first diagnosis of the primary lesion were 96% and 36% for lung and breast carcinomas, respectively. Thirty percent of bone metastases from breast carcinoma were diagnosed more than 5 years after the first diagnosis. Thus careful follow-up must be carried out for a prolonged period. Pain relief was achieved at almost the same rate for bone metastases from lung and breast carcinomas (81% and 85%, respectively), an the rapid onset of pain relief (15 Gy or less) was obtained in about half the patients for both diseases. The rapid onset of pain relief and the lack of association between the onset of pain relief and primary tumor argued against the conventional theory that tumor shrinkage is a component of the initial response. In contrast to the fact that almost all lung carcinoma patients had very poor prognoses, one third of the breast carcinoma patients were alive more than 2 years after palliative radiotherapy. Thust, the late effects of radiation, such as radiation myelopathy, must be always considered especially in breast carcinoma patients even when it is 'just' palliative radiotherapy for bone metastases.

    To determine the microbiology of the bile culture and antimicrobial susceptibility in patients with symptomatic gallstone disease in our setup. Study Design: A descriptive study. Place and Duration of Study: Surgical Department Combined Military Hospital (CMH) Kharian from Oct, 2010 to Jun, 2011. Patients and Methods: A total of 106 patients underwent cholecystectomy due to symptomatic gallstones and their bile was cultured for aerobic and anaerobic bacteria and culture sensitivity was performed. Data was analysed by using statistical package for social sciences (SPSS) version 13. Results: Bile culture was negative in 81 patients (76.4%) and was positive in only 25 patients (23.6%). Escheria Coli was the most common cultured organism in 10 (40%) patients, Klebsiella in 5 (20%) patients, Pseudomonas in 5 (20%) patients, Proteus in 2 (8%) patients, Staphlococcus aureus in 2 (8%) patients and mixed organisms were cultured in 1 patient (4%). Cefoperazone with sulbactum and Amikacin were the most effective prophylactic antibiotics. Conclusion: Bile in majority of patients with symtomatic uncomplicated gallstone disease is sterile. E. coli is the most commonly cultured organism and cefoperazone with sulbactum and amikacin are the most appropriate antibiotics in our setup. (author)

    The aim of this study was to evaluate the feasibility of intraoperative endoscopic ultrasound guidance for excision of symptomatic deep intramural myomas that are not otherwise visible at laparoscopy. Seventeen patients with symptomatic deep intramural myomas who underwent laparoscopic myomectomy with intraoperative endoscopic ultrasound guidance were followed up and reported. All myomas were removed successfully. The endometrium was breached in one patient. All patients were relieved of their symptoms and three patients presenting with infertility conceived. There were no short- or long-term complications associated with the procedure. One patient who had multiple myomas necessitated intravenous iron treatment prior to discharge. Laparoscopic removal of small symptomatic deep intramural myomas is facilitated by the use of intraoperative endoscopic ultrasound that enables exact localisation and correct placement of the serosal incision. Impact statement What is already known on this subject: When the myoma is symptomatic, compressing the endometrium, does not show serosal protrusion and is not amenable to hysteroscopic resection, laparoscopic surgery may become challenging. What do the results of this study add: The use of intraoperative endoscopic ultrasound under these circumstances may facilitate the procedure by accurate identification of the myoma and correct placement of the serosal incision. What are the implications of these findings for clinical practice and/or further research: Intraoperative ultrasound should be more oftenly used to accurately locate deep intramural myomas to the end of making laparoscopy feasible and possibly decreasing recurrence by facilitating removal of otherwise unidentifiable disease.

    In response to a resurgence of symptomatic cases of vitamin D deficiency in a high-risk predominantly ethnic minority population, a programme of universal rather than targeted vitamin D supplementation was begun with a public awareness campaign about the importance of vitamin D. To evaluate the effectiveness of this programme in reducing case numbers. Cases of symptomatic vitamin D deficiency in children under 5 years resident in a primary care trust catchment area presenting at local hospitals were identified through laboratory records of low vitamin D levels which were cross-checked against medical records to confirm the diagnosis. Comparisons were made of the case incidence rate, level of public knowledge and vitamin supplement uptake rate at the onset of the programme in 2005 and 4 years later. The number of cases of symptomatic vitamin D deficiency in those under 5 years fell by 59% (case incidence rate falling from 120/100 000 to 49/100 000) despite the supplement uptake rate rising only to 17%. Public awareness of vitamin D deficiency rose to near universal levels. A programme of universal rather than targeted Healthy Start vitamin D supplementation for pregnant and lactating women and young children has led to a substantial decrease in cases of symptomatic vitamin D deficiency in a high-risk population. Supplementation was also started at a younger age than in the national programme. This approach has implications for the delivery of vitamin D supplementation programmes in similar populations.

    The purpose of the present study was to investigate the correlation between the composition of the bacterial flora isolated from infected root canals of teeth with apical periodontitis with the presence of clinical signs and symptoms, and to test the antibiotic susceptibility of five anaerobic bacteria mostly commonly found in the root canals of symptomatic teeth against various substances using the E-test. Microbial samples were taken from 48 root canals, 29 symptomatic and 19 asymptomatic, using adequate techniques. A total of 218 cultivable isolates were recovered from 48 different microbial species and 19 different genera. Root canals from symptomatic teeth harbored more obligate anaerobes and a bigger number of bacterial species than the asymptomatic teeth. More than 70% of the bacterial isolates were strict anaerobes. Statistical analysis used a Pearson Chi-squared test or a one-sided Fisher's Exact test as appropriate. Suggested relationships were found between specific microorganisms, especially gram-negative anaerobes, and the presence of spontaneous or previous pain, tenderness to percussion, pain on palpation and swelling amoxicillin, amoxicillin + clavulanate and cephaclor were effective against all the strains tested. The lowest susceptibility rate was presented by Prevotella intermedia/nigrescens against Penicillin G. Our results suggested that specific bacteria are associated with endodontic symptoms of infected teeth with periapical periodontitis and the majority of the anaerobic bacterial species tested were susceptible to all antibiotics studied.

    Psychosocial functioning in patients with schizophrenia attended in daily practice is an understudied aspect. The aim of this study was to assess the relationship between symptomatic and psychosocial remission and adherence to treatment in schizophrenia. This cross-sectional, non-interventional, and multicenter study assessed symptomatic and psychosocial remission and community integration of 1,787 outpatients with schizophrenia attended in Spanish mental health services. Adherence to antipsychotic medication in the previous year was categorized as≥80% vs.<80%. Symptomatic remission was achieved in 28.5% of patients, and psychosocial remission in 26.1%. A total of 60.5% of patients were classified as adherent to antipsychotic treatment and 41% as adherent to non-pharmacological treatment. During the index visit, treatment was changed in 28.4% of patients, in 31.1% of them because of low adherence (8.8% of the total population). Adherent patients showed higher percentages of symptomatic and psychosocial remission than non-adherent patients (30.5 vs. 25.4%, P<.05; and 32 vs. 17%, P<.001, respectively). Only 3.5% of the patients showed an adequate level of community integration, which was also higher among adherent patients (73.0 vs. 60.1%, P<.05). Adherence to antipsychotic medication was associated with symptomatic and psychosocial remission as well as with community integration. Copyright © 2016 SEP y SEPB.

  17. Progesterone for Symptomatic Perimenopause Treatment - Progesterone politics, physiology and potential for perimenopause.

    Prior, J C

    2011-01-01

    Perimenopause, women's normal midlife reproductive transition, is highly symptomatic for about 20% of women who are currently inaccurately counseled and inappropriately treated with oral contraceptives, menopausal hormone therapy or hysterectomy. About 80% of perimenopausal women experience vasomotor symptoms (VMS), 25% have menorrhagia, and about 10% experience mastalgia. The majority of women describe varying intensities of sleep, -coping or mood difficulties. Women are more symptomatic because common knowledge inaccurately says that estradiol (E2) levels are dropping/deficient. Evidence shows that with disturbed brain-ovary feedbacks, E2 levels average 26% higher and soar erratically - some women describe feeling pregnant! Also, ovulation and progesterone (P4) levels become insufficient or absent. The most symptomatic women have higher E2 and lower P4 levels. Because P4 and E2 complement/counterbalance each other's tissue effects, oral micronized P4 (OMP4 300 mg at -bedtime) is a physiological therapy for treatment-seeking, symptomatic perimenopausal women. Given cyclically (cycle d 14-27, or 14 on/off) in menstruating midlife women, OMP4 decreases cyclic VMS, improves sleep and premenstrual mastalgia. Menorrhagia is treated with ibuprofen 200mg/6h plus OMP4 cycle d 4-28. For insulin resistance, metformin plus cyclic or daily OMP4 decreases insulin resistance and weight gain. Non-responsive migraines need daily OMP4 plus usual therapies. VMS and insomnia in late perimenopause respond to daily OMP4. In summary, OMP4 is a physiology-based therapy that improves sleep, treats VMS, does not increase breast proliferation or cancer risk, increases bone formation and has beneficial cardiovascular effects. A controlled trial is testing OMP4 for perimenopausal VMS - more evidence-based data are needed.

  18. Immediate versus delayed treatment for recently symptomatic carotid artery stenosis

    Full Text Available ABSTRACT BACKGROUND: The timing of surgery for recently symptomatic carotid artery stenosis remains controversial. Early cerebral revascularization may prevent a disabling or fatal ischemic recurrence, but it may also increase the risk of hemorrhagic transformation, or of dislodging a thrombus. This review examined the randomized controlled evidence that addressed whether the increased risk of recurrent events outweighed the increased benefit of an earlier intervention. OBJECTIVES: To assess the risks and benefits of performing very early cerebral revascularization (within two days compared with delayed treatment (after two days for people with recently symptomatic carotid artery stenosis. METHODS: Search methods: We searched the Cochrane Stroke Group Trials Register in January 2016, the Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library 2016, issue 1, MEDLINE (1948 to 26 January 2016, EMBASE (1974 to 26 January 2016, LILACS (1982 to 26 January 2016, and trial registers (from inception to 26 January 2016. We also handsearched conference proceedings and journals, and searched reference lists. There were no language restrictions. We contacted colleagues and pharmaceutical companies to identify further studies and unpublished trials Selection criteria: All completed, truly randomized trials (RCT that compared very early cerebral revascularization (within two days with delayed treatment (after two days for people with recently symptomatic carotid artery stenosis. Data collection and analysis: We independently selected trials for inclusion according to the above criteria, assessed risk of bias for each trial, and performed data extraction. We utilized an intention-to-treat analysis strategy. MAIN RESULTS: We identified one RCT that involved 40 participants, and addressed the timing of surgery for people with recently symptomatic carotid artery stenosis. It compared very early surgery with surgery performed after 14 days of

    Full Text Available Abstract Background Previous studies have described an increased risk of developing tibio-femoral osteoarthritis (TF OA, meniscal tears and bursitis among those with a trade as floor layers. The purpose of this study was to analyse symptomatic knee disorders among floor layers that were highly exposed to kneeling work tasks compared to graphic designers without knee-demanding work tasks. Methods Data on the Knee injury and Osteoarthritis Outcome Score (KOOS were collected by questionnaires. In total 134 floor layers and 120 graphic designers had a bilateral radiographic knee examination to detect TF OA and patella-femoral (PF OA. A random sample of 92 floor layers and 49 graphic designers had Magnetic Resonance Imaging (MRI of both knees to examine meniscal tears. Means of the subscales of KOOS were compared by analysis of variance. The risk ratio of symptomatic knee disorders defined as a combination of radiological detected knee OA or MRI-detected meniscal tears combined with a low KOOS score was estimated by logistic regression in floor layers with 95% confidence interval (CI and adjusted for age, body mass index, traumas, and knee-straining sports activities. Symptomatic knee OA or meniscal tears were defined as a combination of low KOOS-scores and radiographic or MRI pathology. Results Symptomatic TF and medial meniscal tears were found in floor layers compared to graphic designers with odds ratios 2.6 (95%CI 0.99-6.9 and 2.04 (95% CI 0.77-5.5, respectively. There were no differences in PF OA. Floor layers scored significantly lower on all KOOS subscales compared to graphic designers. Significantly lower scores on the KOOS subscales were also found for radiographic TF and PF OA regardless of trade but not for meniscal tears. Conclusions The study showed an overall increased risk of developing symptomatic TF OA in a group of floor layers with a substantial amount of kneeling work positions. Prevention would be appropriate to reduce the

    To clarify the impact of endoscopic incision (EI) for ureterocele as an initial procedure, by performing a retrospective chart review, focusing on the prevalence of and risk factors for symptomatic urinary tract infection (UTI) after EI. In the present study we included children with ureterocele, managed between September 1994 and April 2016, who were observed conservatively without additional surgical management after EI. Ureterocele was categorized as intravesical or ectopic. Symptomatic UTI was defined as either recurrent non-febrile or febrile UTI. The prevalence of and risk factors for symptomatic UTI were analysed using Cox proportional hazard models or Kaplan-Meier curves, and the log-rank test. A total of 36 children met the inclusion criteria. The median age of the participants at EI was 8.9 months. Eleven children had symptomatic UTIs (febrile, n = 9; recurrent non-febrile, n = 2) during the median follow-up of 75.5 months. Initial symptomatic UTI in each child occurred UTI-free rate after EI was 65.6%. The risk factors for symptomatic UTI were female gender, duplex system, ectopic ureterocele, and unchanged hydronephrosis after EI. The present study determined the critical period and risk factors for symptomatic UTI after EI for the treatment of ureterocele. The results suggest that when conservative management is indicated after EI, patients, especially those with risk factors, should be followed carefully at least for 25 months after EI for symptomatic UTI. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

    Description: The fuel segments for the high burn-up integral rod behaviour test IFA-597 were taken from fuel rod 33-25065, which was irradiated in the Ringhals 1 BWR for approximately 12 years. The irradiation of this rod and its sibling rod 33-25046 was performed in two stages. During the first irradiation, 1980 to 1986, the rods were part of Ringhals assembly 6477 and an approximate rod averaged burn-up of 31 MWd/kg UO 2 was reached. The rods were then placed into fuel assembly 9902 for a second period of irradiation from 1986 to 1992. The location of the fuel rods 33-25065 and 33-25046 in this assembly were in positions 9902/D and 9902/E4 respectively. A final rod averaged burn-up of 52 MWd/kg UO 2 was achieved. The burn-up at the location of the Halden segments was estimated as 59 MWd/kg UO 2 , well beyond the formation of High Burn-up Structure (Hobs) formation at the pellet rim. At the rim, the burn-up was estimated as 130 MWd/kg UO 2 . After commercial irradiation, PIE was performed at Studsvik. Inner and outer clad oxide thickness measurements were 42 and 5 microns respectively. The measured cold rod diameter varied between 12.20 and 12.25 mm, thus only a small amount of creep-down had occurred from the original diameter of 12.25 mm. Cold gap measurements were taken by diametral compression of the clad onto the fuel. The stiffness changes twice during these measurements, the first (relocated gap) associated with the onset of pellet fragment movement, the second (compressed gap) when the fragments are together and the pellet is compressed. For these rods, the compressed diametral gap was measured as 30 microns. This is in agreement with the pellet and cladding being in contact during the final irradiation cycle, i.e., at ∼12 kW/m. FGR measurements were made after puncturing and values of 2.5%-3.3% were calculated from the extracted gas. The uncertainty is due to different methods of calculation. Ceramography showed a normal crack pattern and no evidence of

    The aim of this study was to investigate whether there are differences in technique between young adults with and without musculoskeletal symptoms when using a mobile phone for texting and whether there are differences in muscle activity and kinematics between different texting techniques. A total of 56 young adults performed a standardised texting task on a mobile phone. Their texting techniques were registered using an observation protocol. The muscular activity in six muscles in the right forearm/hand and both shoulders were registered by surface electromyography and the thumb abduction/adduction and flexion/extension were registered using a biaxial electrogoniometer. Differences in texting techniques were found between the symptomatic and the asymptomatic group, with a higher proportion of sitting with back support and forearm support and with a neutral head position in the asymptomatic group. Differences in muscle activity and kinematics were also found between different texting techniques. The differences in texting technique between symptomatic and asymptomatic subjects cannot be explained by them having symptoms but may be a possible contribution to their symptoms. STATEMENT OF RELEVANCE: There has been a dramatically increased use of mobile phones for texting especially among young people during the last years. A better understanding of the physical exposure associated with the intensive use is important in order to prevent the development of musculoskeletal disorders and decreased work ability related to this use.

    Full Text Available Toxoplasmosis in sheep is a disease of great importance in veterinary medicine, which causes economic losses in livestock and has a great impact on human health, since consumption of infected meat facilitates transmission of zoonotic infections. Blood samples from sheep (n = 360 were collected from 13 farm properties in the municipality of Lages, Santa Catarina, to estimate the prevalence of toxoplasmosis and identify risk factors associated with Toxoplasma gondii infection. T. gondii, antibodies were investigated by means of the indirect immunofluorescence assay (IFA and enzyme-linked immunosorbent assay (ELISA. Animals infected with T. gondii were found on 100% of the farms. IFA detected 56.9% (205/360 and ELISA 42.5% of the infected sheep. Breed was the only risk factor associated with the presence of T. gondii antibodies. ELISA showed sensitivity of 61%, specificity of 82% and kappa of 0.41, which was considered moderate. This allows use of ELISA as an alternative technique for diagnosing T. gondii in sheep.A toxoplasmose ovina é uma doença parasitária de elevada importância em medicina veterinária e em saúde pública, acarretando prejuízos na produção animal, gerados pelas perdas reprodutivas e econômicas, além de sua implicação na saúde humana, já que o consumo de carne infectada facilita a transmissão zoonótica. Para determinar a prevalência e identificar fatores de risco para a infecção por T. gondii em ovinos de Lages, Santa Catarina, amostras de sangue (n = 360 foram coletadas em 13 propriedades. Cada criador respondeu a um questionário para permitir a identificação dos fatores de risco da infecção. A pesquisa de anticorpos foi realizada por meio da Reação de Imunofluorescência Indireta (RIFI > 64 e do Ensaio Imunoenzimático Indireto (ELISA. Em 100% das propriedades foram encontrados animais positivos. Pela RIFI, 205 (56,94% ovinos apresentaram anticorpos contra T. gondii e pelo ELISA, 153 (42

    This work summarizes the efficacy of pharmacotherapy in the chronic course of schizophrenia and unipolar depresion. It is aimed to answer three questions: does it cure these diseases? Does it exert any significant effect on the symptomatic presentation of the disorders? Which is its action on the social dysfunction provoked by schizophrenia or depression? A conceptual analysis of available bibliography was performed. It could be concluded that antypsychotics improve the symptomatic course of schizophrenia, although their efficacy is limited, and that these drugs does not act on the social dysfunction provoked by the disease. With respect to depression, it could be concluded that a significant proportion of patients remain symptomatic despite receiveng adequate treatments. No data about efficacy of pharmacotherapy on the dysfunction resultant from unipolar depression is available.

    Molecular epidemiological studies on circulating strains of CMV in cogenital/perinatal infections have not been done earlier in this region. To study the glycoprotein B genotypes in babies with symptomatic congenital/perinatal CMV infection and to assess the possible influence of genotype on the outcome of the infection. Clinical samples (blood and urine) of symptomatic babies are sent to the Virology Department of NCDC, Delhi for the diagnosis of congenital infections. 375 clinical samples of infants (newborn - 6 months old) were included for the study. Serum samples were subjected to ELISA for detection of IgM antibodies against CMV. DNA isolation and amplification of CMV genomic DNA targeting gB gene fragment by nested PCR, was carried out in the samples. The amplified fragment including the cleavage site was subjected to RFLP using restriction enzymes Rsal and Hinf1. They were also verified by sequencing using Big Dye Terminator chemistry. 75 samples out of 375 tested were confirmed positive for CMV infection by serology and PCR. Both RFLP and sequencing of gB gene fragment showed that gB 1, 2 and 3 genotypes were in circulation. gB 3 was the most prevalent genotype in symptomatic infants. Hepatosplenomegaly was the most common feature in gB-3 genotype of CMV. gB2 congenital CMV infection was more commonly associated with long term sequelae.

    Textbooks and reviews do not mention the association of symptomatic primary Epstein-Barr virus infectious mononucleosis with acute kidney injury in subjects without immunodeficiency or autoimmunity. Stimulated by our experience with two cases, we performed a review of the literature. The literature documents 38 cases (26 male and 12 female individuals ranging in age from 0.3 to 51, median 18 years) of symptomatic primary Epstein-Barr virus infectious mononucleosis complicated by acute kidney injury: 27 acute interstitial nephritides, 1 jaundice-associated nephropathy, 7 myositides and 3 hemolytic uremic syndromes. Acute kidney injury requiring renal replacement therapy was observed in 18 (47%) cases. Acute kidney injury did not resolve in one patient with acute interstitial nephritis. Two patients died because of systemic complications. The remaining 35 cases fully recovered. In individuals with acute symptomatic Epstein-Barr virus infectious mononucleosis, a relevant kidney injury is rare but the outcome potentially fatal. It results from interstitial nephritis, myositis-associated acute kidney injury, hemolytic uremic syndrome or jaundice-associated nephropathy. Copyright © 2017 Elsevier B.V. All rights reserved.

    Gingivitis in traditional national dentistry referred to independent diseases or symptomatic condition in periodontitis and classified morphologically. The diagnostic features of the diseases are characteristic, but the clinical presentation of symptomatic gingivitis and patterns of bone destructions may vary between patients. Successful treatment of the disease depends from proper diagnosis and advanced disease stages, but for symptomatic gingivitis that accompanying chronic periodontitis, protocols include surgical excision. Despite of the high prevalence of chronic generalized periodontitis, its active treatment often start in severe destruction and bone loss (2-3 stage severity). Today etiotropic antimicrobial therapy is real way to control microbial biofilm and has solid evidence base. Applying of etiotropic antimicrobial therapy as systemic azithromycin with timely treatment of mild to moderate periodontal and bone destruction may reduce severe periodontitis incidence of and treatment-related complications in the future. This paper attempts to describe the clinical diagnostic features and the current treatment options along with a suggested protocol for comprehensive management of chronic generalized periodontitis and hypertrophic gingivitis patient with case reports and a brief review.

    Certain patients with coronary artery disease (CAD) may have neither ST depression nor chest pain during exercise despite the presence of myocardial ischemia. The frequency and characteristics of such electrocardiographically and symptomatically silent ischemia were studied in 171 patients with both angiographically documented CAD and scintigraphically documented ischemia. Fifty-six (33%) of 171 patients had neither ST depression nor chest pain (Group N), and 115 (67%) had ST depression and/or chest pain (Group P). The two groups were similar with respect to age, gender, the prevalence of prior infarction, and peak systolic blood pressure. Group N patients, however, had a higher mean peak heart rate and rate-pressure product, less severe scintigraphic ischemia, a lower lung thallium-201 uptake, and a smaller number of diseased vessels. Stepwise discriminant analysis showed a history of effort angina, lung thallium-201 uptake, and scintigraphic severity of ischemia to be significant discriminators between Groups N and P. In conclusion, electrocardiographically and symptomatically silent ischemia may be common during exercise in patients with CAD, and less severe ischemia may be one of important determinants.

    2009-01-01

    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.

    Recent studies have investigated the occurrence of human cytomegalovirus and Epstein-Barr Virus in samples from apical periodontitis lesions and a role in the pathogenesis of this disease has been suggested. Because genotype distribution and seroprevalence of EBV and HCMV differ among populations, it is important to determine the presence of these viruses in endodontic periapical lesions of different populations. The aims of this study were to determine the presence of HCMV and EBV DNAs in samples from Turkish patients with symptomatic and asymptomatic apical periodontitis lesions using real-time polymerase chain reaction method and to evaluate their presence in both symptomatic and asymptomatic apical periodontitis lesions. Periapical samples were collected from 12 asymptomatic and 16 symptomatic periapical lesions in conjunction with apicectomy. HCMV and EBV DNAs were identified in the samples by real-time PCR. The chi-squared test with Yates's correction or the Fisher's exact test was used to analyse the significance of differences. HCMV DNA was detected in 10 of the 16 (62.5%) symptomatic and in five of the 12 (41.7 %) asymptomatic periapical study lesions. The EBV DNA was identified in seven of the 16 (43.7 %) symptomatic and three of the 12 (25 %) asymptomatic periapical lesions. The difference in occurrence of HCMV and EBV DNA between symptomatic and asymptomatic periapical lesions was not statistically significant. (All comparisons have p > 0.05). Our findings suggest that HCMV and EBV is a frequent inhabitant of both symptomatic and asymptomatic apical periodontitis lesions of endodontic origin in Turkish population.

    Objective: To assess the safety, feasibility, short- and mid-term efficacy of wingspan stent for treating patients with symptomatic intracranial artery stenosis. Methods: A total of 113 patients with severe symptomatic intracranial stenosis were enrolled and Gateway-wingspan stenting were performed on all patients. The technical success, the pre- and post-stenting stenosis, perioperative complications, clinical outcome and restenosis rates were recorded, and chi-square test was used for analysis of complication rate by comparing our results with the results of Warfarin-Aspirin Symptomatic Intracranial Disease (WASID) study and NIH multi-center Wingspan stenting trial. Results: The technical success rate was 99.1% (112/ 113). The mean pre and post-stent stenoses were (80.7±9.3)% and (27.7±9.7)% (χ 2 =9.397, P<0.05). The total complication rate was 4.4% (5/113) during the follow-up (mean 14.5 months, range 1-28 months), and the frequency of' restenosis was 12.5% (5/40) at 6 months. The primary endpoint events, ischemic stroke, and lesion-related ischemic stroke were lower in our study (4.5%, 3.5%, 3.5%) compared with the results of WASID trial (21.1%, 20.4%, 15.0%, P<0.05). For those with poor outcome in the three high-risk sub-groups which were with more than 70% stenosis, or last event from the treatment was less than 17 days, or NIHSS was above 1, a better outcome was observed in our group (4.5%, 4.7% and 2.0% in our study, 19.0%, 17.0% and 19.6% in previous study, P<0.05). The medium-term efficacy in this group (4.5%) significantly improved compared with NIH study (14.0%, P< 0.05). Conclusions: Wingspan stenting for symptomatic intracranial arterial stenosis is with good safety, feasibility and low perioperative stroke rate and mortality. The incidence of primary endpoint events and the ischemic events are lower than those of medication group, and the efficacy of stenting is significantly better than medication even in high-risk population.

    The objective of this study was to present our experience with laparoscopic management of symptomatic simple renal cysts. From April 2004 to November 2006, 21 patients (10 men; 11 women) underwent laparoscopic decortication for simple renal cysts at our department and were included in the analysis. All procedures were carried out by one surgeon using a transperitoneal approach. Patients underwent radiological follow-up with computerized tomography and/or ultrasonography. Procedural success was defined as no recurrence of the cyst and complete pain relief. Symptomatic success was defined as a significant pain decrease. All 21 procedures were completed laparoscopically, without major complications or conversion to open surgery. Estimated mean blood loss during surgery was about 50 mL. Patients were hospitalized for a mean of 1.9±1.1 (range: 1-5) days. Age of the patients and size and location of the cysts, had no relationship with the duration of operation as well as the length of hospital stay (P>0.05). Patients who experienced complete pain relief had significantly larger cyst sizes compared with patients with a partial pain decrease (7.3±1.1 vs 9.1±2.0, respectively; P=0.023, F=0.606). All patients had negative cytological and pathological findings for malignancy or any other abnormalities. At 16.6 months of mean follow up, none of the patients reported symptomatic and/or radiologic failure. Laparoscopic transperitoneal decortication represents an effective and safe treatment option in the management of symptomatic renal cysts. (author)

    BACKGROUND: Cerebral microembolic signals (MES) may predict increased stroke risk in carotid stenosis. However, the relationship between platelet counts or platelet activation status and MES in symptomatic versus asymptomatic carotid stenosis has not been comprehensively assessed. SETTING: University teaching hospitals. METHODS: This prospective, pilot observational study assessed platelet counts and platelet activation status, and the relationship between platelet activation and MES in asymptomatic versus early (≤4 weeks after TIA\\/stroke) and late phase (≥3 months) symptomatic moderate or severe (≥50%) carotid stenosis patients. Full blood count measurements were performed, and whole blood flow cytometry was used to quantify platelet surface activation marker expression (CD62P and CD63) and circulating leucocyte-platelet complexes. Bilateral simultaneous transcranial Doppler ultrasound monitoring of the middle cerebral arteries was performed for 1 hour to classify patients as MES-positive or MES-negative. RESULTS: Data from 31 asymptomatic patients were compared with 46 symptomatic patients in the early phase, and 35 of these patients followed up to the late phase after symptom onset. The median platelet count (211 vs. 200 x 10(9) \\/L; p=0.03) and the median% lymphocyte-platelet complexes were higher in early symptomatic than asymptomatic patients (2.8 vs. 2.4%, p=0.001). The% lymphocyte-platelet complexes was higher in early symptomatic than asymptomatic patients with ≥70% carotid stenosis (p=0.0005), and in symptomatic patients recruited within 7 days of symptom onset (p=0.028). Complete TCD data were available in 25 asymptomatic and 31 early phase symptomatic, and 27 late phase symptomatic patients. 12% of asymptomatic versus 32% of early phase symptomatic (p=0.02) and 19% of late phase symptomatic patients (p=0.2) were MES-positive. Early symptomatic MES-negative patients had a higher% lymphocyte-platelet complexes than asymptomatic MES

  15. Dynamic Computational Model of Symptomatic Bacteremia to Inform Bacterial Separation Treatment Requirements.

    Directory of Open Access Journals (Sweden)

    Sinead E Miller

    Full Text Available The rise of multi-drug resistance has decreased the effectiveness of antibiotics, which has led to increased mortality rates associated with symptomatic bacteremia, or bacterial sepsis. To combat decreasing antibiotic effectiveness, extracorporeal bacterial separation approaches have been proposed to capture and separate bacteria from blood. However, bacteremia is dynamic and involves host-pathogen interactions across various anatomical sites. We developed a mathematical model that quantitatively describes the kinetics of pathogenesis and progression of symptomatic bacteremia under various conditions, including bacterial separation therapy, to better understand disease mechanisms and quantitatively assess the biological impact of bacterial separation therapy. Model validity was tested against experimental data from published studies. This is the first multi-compartment model of symptomatic bacteremia in mammals that includes extracorporeal bacterial separation and antibiotic treatment, separately and in combination. The addition of an extracorporeal bacterial separation circuit reduced the predicted time of total bacteria clearance from the blood of an immunocompromised rodent by 49%, compared to antibiotic treatment alone. Implementation of bacterial separation therapy resulted in predicted multi-drug resistant bacterial clearance from the blood of a human in 97% less time than antibiotic treatment alone. The model also proposes a quantitative correlation between time-dependent bacterial load among tissues and bacteremia severity, analogous to the well-known 'area under the curve' for characterization of drug efficacy. The engineering-based mathematical model developed may be useful for informing the design of extracorporeal bacterial separation devices. This work enables the quantitative identification of the characteristics required of an extracorporeal bacteria separation device to provide biological benefit. These devices will potentially

    To evaluate the clinical outcomes of symptomatic bone lesions in patients with multiple myeloma (MM) who received local radiotherapy (LRT). Fifty-one patients with 87 symptomatic bone lesions treated via LRT were analyzed. LRT was delivered at a median total dose of 21 Gy (range, 12 to 40 Gy) in a median of 7 fractions (range, 4 to 20 fractions). The clinical outcomes of LRT and the factors affecting treatment response were assessed. After a median follow-up time of 66.7 weeks, symptom relief was achieved for 85 of 87 lesions (97.7%). The median time to symptom relief was 7 days from the start of LRT (range, 1 to 67 days). The duration of in-field failure-free survival ranged from 1.1 to 450.9 weeks (median, 66.7 weeks). The radiation dose or use of previous and concurrent chemotherapy was not significantly associated with in-field failure for LRT (p = 0.354, 0.758, and 0.758, respectively). Symptomatic bone lesions in patients with MM can be successfully treated with LRT. A higher radiation dose or the use of concurrent chemotherapy may not influence the in-field disease control. A relatively low radiation dose could achieve remission of symptoms in patients with MM

    2018-02-02

    To evaluate the incidence of acute symptomatic urolithiasis in the Auckland region. Associated epidemiological factors and stone characteristics were also studied and compared to previous research conducted in order to analyse trends. All patients that presented acutely with symptomatic urolithiasis to the Auckland District Health Board (AHDB) between July 2014 and June 2015 were studied. Clinical data was obtained from medical records and population data was based on estimates provided by the Ministry of Health. Two-tailed tests and the Pearson Chi-Square tests were used for analysis. Overall, 1,125 patients (1,328 events) presented with an incidence of 85 per 100,000 per year, which was lower than that reported in 2006. The highest incidence was found among the Middle Eastern ethnic subgroup (0.130 %), followed by Māori (0.102%), Asian (0.087%), European (0.084%) and Pacific (0.041%) ethnicity. Males were more likely to be affected than females. Urolithiasis was most common in the fifth decade of life (25%). Forty-seven percent of the study population presented with multiple stones and 64% had recurrent urolithiasis or were 'high risk' stone formers. Distal ureteric stones Auckland. This deviation could be attributed to the large influx of Asian immigrants observed in this period of time. A caucasian male, between 40-49 years, with a calculus <5mm in the distal ureter with a history of a previous urolithiasis has the highest chance to present with renal colic.

  2. Acute symptomatic neonatal seizures in preterm neonates: etiologies and treatments.

    Acute symptomatic neonatal seizures in preterm newborns are a relevant clinical challenge due to the presence of many knowledge gaps. Etiology-wise, acute symptomatic seizures have an age-specific epidemiology, with intraventricular hemorrhage and its complications representing the first cause in extremely and very preterm neonates, whereas other etiologies have similar occurrence rates as in full-term infants. Specific treatment strategies for the premature neonates are not yet available. Studies suggest a similarly low response rate with even more unfavorable prognosis than in full-term infants. Pharmacodynamic and pharmacokinetic changes are likely under way during the preterm period, with the potential to affect both effectiveness and safety of antiepileptic drugs in these patients. However, due to the lack of clear evidence to guide prioritization of second-line drugs, off-label medications are frequently indicated by review papers and flow-charts, and are prescribed in clinical practice. We therefore conclude by exploring potential future lines of research. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Gastric lipomas are rare tumors, accounting for 2%-3% of all benign gastric tumors. They are of submucosal or extremely rare subserosal origin. Although most gastric lipomas are usually detected incidentally, they can cause abdominal pain, dyspeptic disorders, obstruction, invagination, and hemorrhages. Subserosal gastric lipomas are rarely symptomatic. There is no report on treatment of subserosal gastric lipomas in the English literature. We present a case of a 50-year-old male with symptom...

    Full Text Available End-of-life patients present a variety of symptoms that cause suffering for them and their respective families. Health professionals throughout their university, internship and medical careers are ill-prepared to manage and improve the quality of life of these patients. This article aims to provide basic skills in the symptomatic management of end-of-life patients, focusing in particular on the control of pain, dyspnoea, fatigue, nausea, vomiting and anorexia. It also aims to draw attention to basic concepts of control concerning refractory symptoms and palliative sedation.

    Panayiotopoulos syndrome (PS) is an age-related seizure susceptibility syndrome that affects the central autonomic system. Although the majority of the few ictal recordings obtained so far suggest an occipital origin, semiological and interictal EEG data appear to favour more extensive involvement. In this study, the characteristics (including those based on semiology and EEG) of children with Panayiotopoulos syndrome (n=24) and those with lesion-related, symptomatic occipital lobe epilepsy (SOLE) (n=23) were compared. Detailed semiological information and EEG parameters including the localisation, distribution, density (n/sec), reactivity, and morphological characteristics of spike-wave foci and their relationship with different states of vigilance were compared between the two groups. The age at seizure onset was significantly younger in patients with symptomatic occipital lobe epilepsy than in those with PS (mean age at onset: 3.4 versus 5.6 years, respectively; p=0.044). Autonomic seizures (p=0.001) and ictal syncope (p=0.055) were more frequent in PS than in symptomatic occipital lobe epilepsy (87.5% and 37.5% versus 43.5% and 13%, respectively). The interictal spike-wave activity increased significantly during non-rapid eye movement (non-REM) sleep in both groups. The spike waves in non-REM seen in PS tended to spread mainly to central and centro-temporal regions. The results indicate that although common features do exist, Panayiotopoulos syndrome differs from symptomatic occipital lobe epilepsy and has a unique low epileptogenic threshold related to particular brain circuits.

  7. Mapping of quantitative adult plant field resistance to leaf rust and stripe rust in two European winter wheat populations reveals co-location of three QTL conferring resistance to both rust pathogens.

    We detected several, most likely novel QTL for adult plant resistance to rusts. Notably three QTL improved resistance to leaf rust and stripe rust simultaneously indicating broad spectrum resistance QTL. The rusts of wheat (Puccinia spp.) are destructive fungal wheat diseases. The deployment of resistant cultivars plays a central role in integrated rust disease management. Durability of resistance would be preferred, but is difficult to analyse. The Austrian winter wheat cultivar Capo was released in the 1989 and grown on a large acreage during more than two decades and maintained a good level of quantitative leaf rust and stripe rust resistance. Two bi-parental mapping populations: Capo × Arina and Capo × Furore were tested in multiple environments for severity of leaf rust and stripe rust at the adult plant stage in replicated field experiments. Quantitative trait loci associated with leaf rust and stripe rust severity were mapped using DArT and SSR markers. Five QTL were detected in multiple environments associated with resistance to leaf rust designated as QLr.ifa-2AL, QLr.ifa-2BL, QLr.ifa-2BS, QLr.ifa-3BS, and QLr.ifa-5BL, and five for resistance to stripe rust QYr.ifa-2AL, QYr.ifa-2BL, QYr.ifa-3AS, QYr.ifa-3BS, and QYr.ifa-5A. For all QTL apart from two (QYr.ifa-3AS, QLr.ifa-5BL) Capo contributed the resistance improving allele. The leaf rust and stripe rust resistance QTL on 2AL, 2BL and 3BS mapped to the same chromosome positions, indicating either closely linked genes or pleiotropic gene action. These three multiple disease resistance QTL (QLr.ifa-2AL/QYr.ifa-2AL, QLr.ifa.2BL/QYr.ifa-2BL, QLr.ifa-3BS/QYr.ifa.3BS) potentially contribute novel resistance sources for stripe rust and leaf rust. The long-lasting resistance of Capo apparently rests upon a combination of several genes. The described germplasm, QTL and markers are applicable for simultaneous resistance improvement against leaf rust and stripe rust.

    Functional deficits are commonly observed in bipolar disorder after symptomatic remission. Social cognition deficits have also been reported, which could contribute to dysfunction in patients with bipolar disorder in remission. Twelve bipolar disorder patients in symptomatic remission (7 patients with bipolar disorder type I and 5 with bipolar disorder type II) and 12 healthy controls completed the Reading the Mind in the Eyes Test and the Faux Pas Test to evaluate theory of mind (ToM). Both groups also completed the Functional Assessment Short Test (FAST). The performance of the bipolar patients in the cognitive component of ToM was below normal, although the difference between the control group was not statistically significant (P=.078), with a trend to a worse performance associated with a higher number of depressive episodes (P=.082). There were no statistically significant differences between groups for the emotional component of ToM. Global functionality was significantly lower in bipolar patients compared to the control group (P=.001). Significant differences were also observed between both groups in five of the six dimensions of functionality assessed. No significant correlation was found between functionality and theory of mind. Bipolar patients in symptomatic remission exhibit impairments in several areas of functioning. Cognitive ToM appears more affected than emotional ToM. Deficits in ToM were not related to functional impairment. Copyright © 2012 SEP y SEPB. Published by Elsevier Espana. All rights reserved.

    To explore the psychological consequences of experiencing symptomatic pulmonary embolism (PE). Qualitative interview-based study using interpretative phenomenological analysis. Outpatients who attended an anticoagulation clinic in a district general hospital. Patients attending an anticoagulation clinic following hospital admission for symptomatic PE were approached to participate. A total of 9 (4 women, 5 men) of 11 patients approached agreed to be interviewed. Participants were aged between 26 and 72 years and had previously experienced a PE between 9 and 60 months (median=26 months, mean=24 months). Audiotaped semistructured qualitative interviews were undertaken to explore participants experiences of having a PE and how it had affected their lives since. Data were transcribed and analysed using interpretative phenomenological analysis to identify emergent themes. Three major themes with associated subthemes were identified. Participants described having a PE as a life-changing experience comprising initial shock, followed by feeling of loss of self, life-changing decisions and behaviour modification. Features of post-traumatic stress disorder (PTSD) were described with flashbacks, hypervigilance and intrusive thoughts being most prevalent. Participants identified several areas of support needed for such patients including easier access to support through information giving and emotional support. Long-term consequences of venous thromboembolism go beyond the physical alone. Patients describe experiencing symptomatic PE to be a life-changing distressing event leading to behaviour modification and in some PTSD. It is likely that earlier psychological intervention may reduce such long-term sequelae.

    To study the possibility of application of nootropics and antioxidants in the complex antiepileptic therapy, we examined 75 patients with symptomatic focal posttraumatic epilepsy. A statistically significant reduction in the number of epileptic seizures, improvement of cognitive function and quality of life of the patients as well as a decrease in the severity of depression and epileptic changes in the EEG were identified. The potentiation of antiepileptic activity of basic drugs, normalization of brain's electrical activity and reduction in EEG epileptiform activity, in particular coherent indicators of slow-wave activity, were noted after treatment with the antioxidant mexidol. A trend towards the improvement of neuropsychological performance and quality of life was observed. There was a lack of seizure aggravation typical of many nootropic drugs. Thus, phenotropil and mexidol can be recommended for complex treatment of symptomatic posttraumatic epilepsy.

    Symptomatic calcific discitis has been reported in the paediatric population but is a rare entity in adults with only eight cases reported in the English literature. We present a case of adult calcific discitis presenting with acute onset back pain. Radiographs and CT demonstrated central T11-T12 disc calcification with diffuse marrow oedema on subsequent MRI. The patient was referred to our spinal oncology unit due to the extensive marrow oedema as a possible underlying primary bone tumour. Review of the CT confirmed an end-plate defect with herniated calcific nucleus pulposus with no underlying bone lesion. Features were in keeping with acute calcific discitis. The patient was treated symptomatically and made an uneventful recovery. We discuss the characteristic imaging features seen on radiograph, CT and MRI and review the current literature. Calcific discitis is a self-limiting pathology requiring symptomatic management only. Radiologists need to be aware of this rare entity as it can occur in adults and may be mistaken for a more sinister pathology such as infective discitis or a bone tumour and lead to further unnecessary imaging or invasive procedures.

    Hydronephrosis in pregnancy is common in the second and third trimester. Only a few cases are symptomatic, caused by a ureteric stone or by the pregnancy itself. The clinical dilemma is when to treat and when not to treat. We propose a multidisciplinary management based on renal ultrasonography to verify hydronephrosis and renography to diagnose obstructive hydronephrosis. Obstruction with a high intra-renal pressure must be treated to avoid kidney dysfunction. Patients with pyonephrosis need immediate treatment.

  16. Indications for Laparoscopic Cholecystectomy or Oral Dissolution Therapy with Ursodeoxycholic Acid in Symptomatic Gallstone Disease

    A large Danish study has shown that high bilirubin plasma levels and the genetic variant rs6742078 TT of the enzyme bilirubin glucuronidase UGT1A1 are associated with an increased risk of developing symptomatic gallstone disease. Recent reports regarding the significant association between bilirubin levels and symptomatic gallstone disease open a new chapter about the indication and exclusion criteria for oral dissolution therapy of symptomatic gallstone disease. A highly select subgroup of patients with small, single, radiolucent cholesterol gallstones who received oral dissolution therapy with ursodeoxycholic acid (UDCA had a reported recurrence of symptomatic gallstone disease of 50% over five years. This is probably related to the persistence of other causal risk factors for gallstones in addition to that of cholesterol suprasaturation. A subgroup of patients with high plasma bilirubin levels and the UGT1A1 genetic variant rs6742078 have a greater risk of recurrence. In conclusion, oral dissolution therapy with UDCA might still be appropriate for patients that refuse laparoscopic cholecystectomy provided they have small (< 0.5 cm, radiolucent cholesterol gallstones and a functioning gallbladder, and have mean plasma bilirubin levels below 1.33 mg/dL and are not homozygous for the UGT1A1 rs6742078 TT genotype.

    Lumbosacral transitional vertebrae (LSTV) are increasingly recognized as a common anatomical variant associated with altered patterns of degenerative spine changes. This review will focus on the clinical significance of LSTV, disruptions in normal spine biomechanics, imaging techniques, diagnosis, and treatment. A Pubmed search using the specific key words "LSTV," "lumbosacral transitional vertebrae," and "Bertolotti's Syndrome" was performed. The resulting group of manuscripts from our search was evaluated. LSTV are associated with alterations in biomechanics and anatomy of spinal and paraspinal structures, which have important implications on surgical approaches and techniques. LSTV are often inaccurately detected and classified on standard AP radiographs and MRI. The use of whole-spine images as well as geometric relationships between the sacrum and lumbar vertebra increase accuracy. Uncertainty regarding the cause, clinical significance, and treatment of LSTV persists. Some authors suggest an association between LSTV types II and IV and low back pain. Pseudoarticulation between the transverse process and the sacrum creates a "false joint" susceptible to arthritic changes and osteophyte formation potentially leading to nerve root entrapment. The diagnosis of symptomatic LSTV is considered with appropriate patient history, imaging studies, and diagnostic injections. A positive radionuclide study along with a positive effect from a local injection helps distinguish the transitional vertebra as a significant pain source. Surgical resection is reserved for a subgroup of LSTV patients who fail conservative treatment and whose pain is definitively attributed to the anomalous pseudoarticulation. Due to the common finding of low back pain and the wide prevalence of LSTV in the general population, it is essential to differentiate between symptoms originating from an anomalous psuedoarticulation from other potential sources of low back pain.

    Dental pain can have a considerable detrimental effect on an individual's quality of life. Symptomatic apical periodontitis and acute apical abscess are common causes of dental pain and arise from an inflamed or necrotic dental pulp, or infection of the pulpless root canal system. Clinical guidelines recommend that the first-line treatment for teeth with symptomatic apical periodontitis or an acute apical abscess should be removal of the source of inflammation or infection by local, operative measures, and that systemic antibiotics are currently only recommended for situations where there is evidence of spreading infection (cellulitis, lymph node involvement, diffuse swelling) or systemic involvement (fever, malaise). Despite this, there is evidence that dentists continue to prescribe antibiotics for these conditions. There is concern that this could contribute to the development of antibiotic-resistant bacterial colonies both within the individual and within the community as a whole. To evaluate the effects of systemic antibiotics provided with or without surgical intervention (such as extraction, incision and drainage of a swelling or endodontic treatment), with or without analgesics, for symptomatic apical periodontitis or acute apical abscess in adults. We searched the following electronic databases: Cochrane Oral Health Group's Trials Register (to 1 October 2013); Cochrane Central Register of Controlled Trials (The Cochrane Library 2013, Issue 9); MEDLINE via OVID (1946 to 1 October 2013); EMBASE via OVID (1980 to 1 October 2013) and CINAHL via EBSCO (1980 to 1 October 2013). We searched the World Health Organization (WHO) International Trials Registry Platform and the US National Institutes of Health Trials Registry (ClinicalTrials.gov) on 1 October 2013 to identify ongoing trials. We searched for grey literature using OpenGrey (to 1 October 2013) and ZETOC Conference Proceedings (1993 to 1 October 2013). We placed no restrictions on the language or date of

    2011-09-01

    Objective: To assess the long-term improvement in symptoms after magnetic resonance-guided focused ultrasound surgery (MRgFUS) for uterine myomas. Methods: Japanese women with symptomatic myomas underwent MRgFUS using the ExAblate 2000 system. The symptom severity score (SSS) was examined before and after the treatment at 3, 6, 12, 24, and 48 months. Simultaneously, we asked the patients' satisfaction level regarding the overall change of subjective symptoms: symptom free, improved a great deal, improved to some extent, no change, or worsened. The myoma volumes were measured at 6, 12, 24, 36 and 48 months after MRgFUS. Results: No severe adverse event occurred with any of the patients. The mean SSS value before treatment was 38.3±21.5 (n = 106), which diminished significantly during follow-up for 3-48 months after treatment. Patients' satisfaction level was favorable, although the response rate was low. Over 80% of the patients replied that their symptoms were improved to at least some extent, and over 50% of the patients replied that their symptoms were improved a great deal. This trend continued throughout this follow up period. The mean myoma volume was also decreased from the pretreatment volume in this follow up period. Conclusion: MRgFUS is an effective and safe method for treating symptomatic uterine myomas. Long-term symptomatic improvement is promising.

    Clinicians generally agree on the association between depression and hypertension. Less clear is if the nature of the link is direct or indirect and if this should be considered confined only to syndromal forms or if it concerns also subsyndromal affective presentations. This study investigated the nature of the association between hypertension and subsyndromal depression in hospitalized hypertensive patients. 196 hypertensive and 96 non hypertensive inpatients underwent a SCID interview, to exclude patients positive for any Axis I or Axis II diagnosis. Symptomatic Subsyndromal Depression (SSD) was identified according to criteria proposed by Judd. Psychopathological assessment was performed with Anxiety Sensitivity Index (ASI) and Hopkins Symptom Checklist-90 (SCL-90). Clinical assessments included blood pressure measurement, evaluation of general health conditions and screening cardiovascular risk factors (smoke, alcohol, body weight, sedentary life style). Hypertensives met more frequently criteria for SSD. They also scored higher on ASI and SCL-90. However, those with more severe physical conditions, if compared with more healthy patients, did not show increased psychopathological severity. Similarly, psychopathological symptom severity did not differ among hypertensives positive for other cardiovascular risk factors, commonly more frequent among depressed subjects. Further analyses are needed to explore the potential advantage obtained on blood pressure control by treating SSD. Hospitalized hypertensives, more frequently satisfied criteria for Symptomatic Subsyndromal Depression. These milder affective forms are probably directly linked to the presence of hypertension, rather than being indirectly associated to physical impairment or to higher prevalence of other cardiovascular risk factors.

Materials and methods. Patients with symptomatic oral lichen planus referring to the Department of Oral Medicine, Faculty of Dentistry at Shahid Beheshti University of Medical Sciences were asked to participate in the study. Twenty-eight patients who were histopathologically diagnosed with lichen planus were divided into two groups (15 in the case and 13 in the control groups. The subjects were randomly assigned to either topical gel of EA or placebo in a double-blind manner. They were then instructed to apply the medication on dried lesions three times daily. Pain and size of the lesions were evaluated after 2 weeks. Data were analyzed by SPSS 12.0 software, using t-test, paired t-test, Fisher’s exact test and chi-square test. Results. Twenty-eight patients (m/f: 7/21 with symptomatic oral lichen planus participated in the study. Fifteen patients (m/f: 4/11 received E A gel and 13 patients (m/f: 3/10 received placebo. There was a 75% decrease in pain (33.3% in the case and 7.7% in the control groups, and a decrease of 50% in size (33.3% in the case group and 75% only in 7.6% of the case group. Conclusion. The results suggest that 19% EA gel is efficient in the treatment of symptomatic oral lichen planus, with antiinflammatory and analgesic effects, as well.

    Previous studies reported inconsistent findings regarding the association of interpersonal problems with therapy outcome. The current study investigates if interpersonal problems predict process and outcome of three different treatments for depression. The data originate from a randomized clinical trial comparing supportive-expressive psychotherapy, antidepressant medication and pill-placebo for treatment of depression. Interpersonal problems were used as predictors of alliance, symptomatic improvement and premature termination of treatment. Interpersonal problems related to communion predicted better alliances, but slower symptomatic improvement. Low agency predicted slower symptomatic improvement in supportive-expressive psychotherapy, but not in the medication or placebo condition. Lower interpersonal distress was associated with an increased likelihood to terminate treatment prematurely. The sample size did not allow the detection of small effects within the treatment groups. Interpersonal problems are influential for the treatment of depression, but parts of their effects depend on the type of treatment. © 2013 Elsevier B.V. All rights reserved.

    Rationale of prostatic artery embolization (PAE) in the treatment of symptomatic benign prostatic hyperplasia is conventionally believed to include two parts: shrinkage of the enlarged prostate gland as a result of PAE-induced ischemic infarction and potential effects to relax the increased prostatic smooth muscle tone by reducing the number and density of α{sub 1}-adrenergic receptor in the prostate stroma. This review describes new insights into the likely mechanisms behind PAE, such as ischemia-induced apoptosis, apoptosis enhanced by blockage of androgens circulation to the embolized prostate, secondary denervation following PAE, and potential effect of nitric oxide pathway immediately after embolization. Studies on therapeutic mechanisms in PAE may shed light on potentially new treatment strategies and development of novel techniques.

    Full Text Available Cytomegalovirus (CMV is the most common cause of congenital infection, and is a major cause of sensorineural hearing loss and neurological disabilities. Evaluating the risk for a CMV infected fetus to develop severe clinical symptoms after birth is crucial to provide appropriate guidance to pregnant women who might have to consider termination of pregnancy or experimental prenatal medical therapies. However, establishing the prognosis before birth remains a challenge. This evaluation is currently based upon fetal imaging and fetal biological parameters, but the positive and negative predictive values of these parameters are not optimal, leaving room for the development of new prognostic factors. Here, we compared the amniotic fluid peptidome between asymptomatic fetuses who were born as asymptomatic neonates and symptomatic fetuses who were either terminated in view of severe cerebral lesions or born as severely symptomatic neonates. This comparison allowed us to identify a 34-peptide classifier in a discovery cohort of 13 symptomatic and 13 asymptomatic neonates. This classifier further yielded 89% sensitivity, 75% specificity and an area under the curve of 0.90 to segregate 9 severely symptomatic from 12 asymptomatic neonates in a validation cohort, showing an overall better performance than that of classical fetal laboratory parameters. Pathway analysis of the 34 peptides underlined the role of viral entry in fetuses with severe brain disease as well as the potential importance of both beta-2-microglobulin and adiponectin to protect the injured fetal brain infected with CMV. The results also suggested the mechanistic implication of the T calcium channel alpha-1G (CACNA1G protein in the development of seizures in severely CMV infected children. These results open a new field for potential therapeutic options. In conclusion, this study demonstrates that amniotic fluid peptidome analysis can effectively predict the severity of congenital CMV

    Aim: To evaluate the prevalence of coronary artery disease (CAD) in relation to risk of coronary heart disease (CHD) and assess plaque characteristics from coronary computed tomography (CT) angiography in asymptomatic and symptomatic patients. Materials and methods: Three hundred and ninety consecutive patients [asymptomatic group, n = 138; symptomatic group (atypical or non-anginal chest pain), n = 252] were retrospectively enrolled. They were subsequently classified into three CHD risk categories, based on the National Cholesterol Education Program guidelines, and 10 year risks of coronary events were calculated using Framingham risk score. CT was evaluated for stenosis, plaque composition, and coronary calcium scores. Results: CAD was observed in 42% of the asymptomatic group and 62% of the symptomatic group. In the former, the prevalence of CAD in low-, moderate- and high-risk subgroups was 21.4, 47.4 and 65%, respectively, and was 33.3, 74.4, and 72.4% in the symptomatic group. Framingham 10-year risks of coronary events were significantly higher in patients with CAD than in normal participants, and receiver operating characteristics curves showed that discriminatory power was poor in the asymptomatic group and symptomatic men, and good in symptomatic women. Of the participants in the asymptomatic group, 12% exhibited only non-calcified plaques and of the symptomatic group, 7% exhibited only non-calcified plaques. The coronary calcium score was significantly higher for significant stenosis than for non-significant stenosis in both groups. Conclusions: The prevalence of CAD was not negligible even in subgroups with low-to-moderate CHD risk. Additionally, the Framingham risk score was effective for predicting CAD only in symptomatic women. Coronary calcium scores correlated with significant stenosis; however, a sizeable percentage of both groups had only non-calcified plaques.

    Whether cerebral artery endothelial dysfunction is a key factor of symptomatic lacunar stroke and cerebral small vessel disease remains unclear. Cerebral and extracerebral vasoreactivity were measured in 81 patients with recent symptomatic lacunar stroke and in 81 control subjects matched for main vascular risk factors. Cerebral vasoreactivity and carotid endothelial-dependent vasodilation were measured after five-minutes of carbon dioxide-induced hypercapnia. Brachial endothelial-dependent vasodilation was assessed after hyperemia induced by deflating a cuff around the forearm previously inflated to 200 mmHg for four-minutes. Carotid and brachial endothelial-independent vasodilation were measured five-minutes after administration of sublingual nitroglycerin 300 μg. Brain magnetic resonance imaging were analyzed in lacunar stroke patients. One-month after stroke onset, patients had more severely impaired cerebral vasoreactivitys than matched controls (mean ± standard deviation, 14·4 ± 12·1% vs. 19·4 ± 17·4%; P = 0·049). Severe alterations of both carotid and brachial endothelial-dependent and at a lesser degree of carotid and brachial endothelial-independent vasodilation were observed in both groups. After adjustment for confounders, subjects with a cerebral vasoreactivity value in the two lower tertiles (≤19·6%) were more likely to have had a symptomatic lacunar stroke (adjusted odds ratio, 3·78; 95% confidence interval, 1·42 to 10·08; P = 0·008). Only alteration of brachial endothelial-independent vasodilation correlated with parenchymal abnormalities, namely microbleeds and leukoaraiosis. While abnormalities in extracerebral vasoreactivity seem related to vascular risk factors, the severity of endothelial dysfunction in cerebral arteries may be determinant in the occurrence of symptomatic lacunar stroke in patients with small vessel disease. © 2012 The Authors.

    Symptomatic extramedullary hematopoiesis (EH) is a rare but potentially severe phenomenon which occurs in β-thalassemia. There are no treatment guidelines. Retrospective single centre study including the cases of symptomatic EH encountered between 1997 and 2014 in a unit specialised in red blood cell genetic disorders. Description of clinical, biological and radiological characteristics of the patients, treatments received, and outcomes. Among 182 β-thalassemia patients followed during the study period, 7 cases of symptomatic EH were diagnosed. They were 5 men and 2 women, and their mean age was 37 years. Four patients were splenectomised, two patients were regularly transfused, and four patients had already received erythropoietin. EH was localised in intravertebral areas and responsible for dorsal spinal cord compression in 5 patients, in paravertebral dorsal area in 1 patient, and in presacral area in 1 patient. The mean hemoglobin level at diagnosis was 7.9 g/dL. Treatment administered included: red cell transfusion in 6 cases, associated with hydroxyurea in 5 cases and/or radiotherapy in 3 patients. One patient was treated with surgery and HU. After a median follow-up of 41 months, clinical recovery was complete in 2 patients and partial in 5 patients. EH must be suspected in β-thalassemia in patients presenting clinical signs of organ compression, and a typical radiological aspect. The functional prognosis depends on the rapidity of treatment, which includes red blood cell transfusion, hydroxyurea, radiotherapy, and rarely surgery. Long-term outcome is uncertain.

    Full Text Available Background: There is a scarcity of data on asthenopia and accommodative disorders in children in Ghana as optometrists sometimes fail to carry out comprehensive assessments because of the lack of appropriate instruments. Aim: To establish the prevalence of asthenopic symptoms and symptomatic accommodative disorders among Junior High School children in Cape Coast metropolis (in their habitual vision state and to investigate if there are any associations between asthenopic symptoms and the disorders. Method: A prospective cross-sectional school-based study using a multistage sample of 627 participants aged 12–17 years from Junior High Schools in Cape Coast metropolis, Ghana, was conducted. Participants completed a reliable asthenopic symptoms questionnaire (Cronbach’s α = 0.866, and 220 participants who expressed two or more severe or very severe symptoms were selected for comprehensive accommodative system assessment over their habitual vision state. Results: The prevalence of symptoms of asthenopia (two or more severe or very severe and symptomatic accommodative disorders were 35.1% and 17.4% respectively. For specific symptomatic accommodative disorders, the prevalence was as follows: 7.7% accommodative insufficiency, 4.5% accommodative infacility, 1.4% accommodative excess and 3.8% accommodative fatigue. There were significant associations between some specific accommodative disorders and some specific asthenopic symptoms even though these asthenopic symptoms overlapped in other accommodative disorders. Conclusion: Specific asthenopic symptoms do not discriminate between the presences of specific types of accommodative disorders. A comprehensive accommodative system assessment with appropriate instruments is relevant to the diagnosis and management of accommodative disorders to relieve asthenopic symptoms.

    To determine the prevalence of acute symptomatic seizures in infants with supratentorial intracranial hemorrhage, to identify potential risk factors, and to determine the effect of acute seizures on long-term morbidity and mortality. Children less than 24 months with intracranial hemorrhage were identified from a neurocritical care database. All patients who received seizure prophylaxis beginning at admission were included in the study. Risk factors studied were gender, etiology, location of hemorrhage, seizure(s) on presentation, and the presence of parenchymal injury. Acute clinical and electrographic seizures were identified from hospital medical records. Subsequent development of late seizures was determined based on clinical information from patients' latest follow-up. Patients with idiopathic neonatal intracranial hemorrhage, premature infants, and those with prior history of seizures were excluded from analysis. Seventy-two infants met inclusion criteria. None. Forty percent of infants had acute symptomatic seizures. The prevalence was similar regardless of whether etiology of hemorrhage was traumatic or nontraumatic. Seizures on presentation and parenchymal injury were independent risk factors of acute seizures (p = 0.001 and p = 0.006, respectively). Younger children and women were also at higher risk (p Acute seizures were not predictive of mortality, but nearly twice as many patients with acute seizures developed late seizures when compared with those without. Electrographic seizures and parenchymal injury were also predictive of development of late seizures (p hemorrhage are at high risk for acute symptomatic seizures. This is regardless of the etiology of hemorrhage. Younger patients, women, patients with parenchymal injury, and patients presenting with seizure are most likely to develop acute seizures. Although the benefits of seizure prophylaxis have not been studied in this specific population, these results suggest that it is an important component

    Full Text Available Simple renal cysts, although common in adults, are rare in children. They are usually discovered incidentally in the course of the study of other urinary tract symptoms, although they are not always asymptomatic. Renal cysts can be classified as being either simple or complex. The purpose of this review is to present our case series of simple symptomatic renal cysts treated with laparoscopy. Nineteen patients with symptomatic renal cysts (6 to 13.5 cm were referred to our institution between January 2006 and January 2017. They comprised 12 (40.5% females and seven (59.5% males, aged 8 to 15, with a mean age of 12.2 years. Of these patients, nine had previously been treated unsuccessfully by ultrasound-guided aspiration/alcoholization with 95%-ethanol, between 9 and 13 months prior to the laparoscopy. Five patients had undergone one treatment and four had undergone two treatments. All of the patients were treated by laparoscopic threetrocar deroofing. The cysts were opened and the wall excised using scissors and a monopolar hook. In most cases, to better handle the edges of the cyst and obtain a better grip, a needle was used to aspirate a small amount of fluid (used for cytological examination. The wall of the cyst was excised, the cyst edges were sealed, and the perirenal fat was placed on the bottom of the cyst (wadding technique. The mean operating time was 95 minutes (range 50- 150. The postoperative course was uneventful for all of the patients. The hospital stay ranged from one to three days. All of the patients were asymptomatic following the treatment. At a mean follow-up time of 3.6 years, none of the patients had experienced a recurrence. Renal function, as assessed by a MAG3 renal scintigraphy scan, was well-preserved in all of the patients, and all of them undergo an annual ultrasound scan.

    Computed tomographic colonography (CTC) is a minimally invasive technique for imaging the entire colon. Based on a helical thin-section CT of the cleansed and air-distended colon, two-dimensional and three-dimensional projections are used for image interpretation. Several clinical improvements in patient preparation, technical advances in CT, and new developments in evaluation software have allowed CTC to develop into a powerful diagnostic tool. It is already well established as a reliable diagnostic tool in symptomatic patients. Many experts currently consider CTC a comparable alternative to conventional colonoscopy, although there is still debate about its sensitivity for the detection of colonic polyps in a screening population. This article summarizes the main indications, the current techniques in patient preparation, data acquisition and data analysis as well as imaging features for common benign and malignant colorectal lesions

    Disc prolapse presenting with sciatica may be associated with enhancement of the symptomatic nerve root following magnetic resonance imaging (MRI) with intravenous gadolinium (Gd)-DTPA. Previous studies have shown, however, that this does not occur in all cases. The aim of this study was to assess the incidence of nerve root enhancement in patients with sciatica and disc prolapse and to try to identify any specific features that might be associated with the phenomenon. A total of 227 patients presenting with low back pain and/or sciatica underwent a MRI study of the lumbar spine with intravenous contrast enhancement. Nineteen of 81 (23.5 %) patients with disc prolapse demonstrated nerve root enhancement. Nerve root enhancement had a highly significant association with sequestrated disc lesions (13/19, 68 %; P < 0.0005), and was primarily seen in the symptomatic ipsilateral nerve root (16/19, 84 %). The sensitivity of nerve root enhancement associated with disc prolapse was 23.5 % with a specificity of 95.9 %, a positive predictive value of 76 % and a negative predictive value of 69.3 %. Nerve root enhancement may be indicative of the symptomatic level but its poor sensitivity negates the routine use of Gd-DTPA in MRI for sciatica. (orig.) With 4 figs., 1 tab., 37 refs.

    No previous studies have reported the radiological features of patients requiring surgery in symptomatic lumbar foraminal stenosis (LFS). This study aims to investigate the diagnostic accuracy of a novel technique, foraminal stenotic ratio (FSR), using three-dimensional magnetic resonance imaging for LFS at L5-S by comparing patients requiring surgery, patients with successful conservative treatment, and asymptomatic patients. This is a retrospective radiological comparative study. We assessed the magnetic resonance imaging (MRI) results of 84 patients (168 L5-S foramina) aged ≥40 years without L4-L5 lumbar spinal stenosis. The foramina were divided into three groups following standardized treatment: stenosis requiring surgery (20 foramina), stenosis with successful conservative treatment (26 foramina), and asymptomatic stenotic foramen (122 foramina). Foraminal stenotic ratio was defined as the ratio of the length of the stenosis to the length of the foramen on the reconstructed oblique coronal image, referring to perineural fat obliterations in whole oblique sagittal images. We also evaluated the foraminal nerve angle and the minimum nerve diameter on reconstructed images, and the Lee classification on conventional T1 images. The differences in each MRI parameter between the groups were investigated. To predict which patients require surgery, receiver operating characteristic (ROC) curves were plotted after calculating the area under the ROC curve. The FSR showed a stepwise increase when comparing asymptomatic, conservative, and surgical groups (mean, 8.6%, 38.5%, 54.9%, respectively). Only FSR was significantly different between the surgical and conservative groups (p=.002), whereas all parameters were significantly different comparing the symptomatic and asymptomatic groups. The ROC curve showed that the area under the curve for FSR was 0.742, and the optimal cutoff value for FSR for predicting a surgical requirement in symptomatic patients was 50

    Aggressive risk factor modification, change of eating habits, exercise programs, and forceful antiplatelet therapy are the most important tools for the treatment of PAOD in symptomatic patients suffering from intermittent claudication. There are however no guidelines for revascularization at this stage. Endovascular treatment has been increasingly utilized over the last decade and increasingly displaced vascular surgery. Amongst numerous endovascular techniques beside PTA, stents meanwhile play the most important role due to constant technical progress. Results regarding the rate of restenosis or patency rates still remain worse compared to other vascular beds. This paper gives a review over recent results, currently available stent techniques, and possible indications for the endovascular therapy of an artery, which has turned out to be the biggest ordeal for material and construction of stents.

    The cladding corrosion test (IFA-638) is being performed to investigate the corrosion properties of different modern PWR cladding materials. The experimental results are evaluated by the corrosion models EPRI/KWU/CE, ESCORE, NEPLC, and COCHISE. When comparing the measured and the predicted oxide thickness, the following conclusions can be drawn: 1. Considering the fresh material parts (lower parts) of each rod, the oxide thickness calculations of all models under-predicted the measured values by up to 50% after 118 days of exposure. The NEPLC model, however, showed good agreement for 263 days of exposure, while the COCHISE and EPRI/KWU/CE-ESCORE models over-predicted (about +50%) and under-predicted (about -42%), respectively. 2. The oxide layer thickness on the pre-irradiated parts (upper parts) of each rod is well predicted by the COCHISE model after 118 days of exposure, but the other models over-predicted the thickness. All the models over-predicted the oxide thickness after 263 days of exposure, and the divergency between the measured and calculated oxide thickness became larger. 3. The differences in the calculated oxide thickness between the models at low burnup (fresh parts) are attributed to the different transition point determinations of the models. 4. Comparing the measurements with the calculations from the pre-irradiated parts of each rod, the overall over-prediction could be accounted for by the fact that the post-transition regime of all four models was calibrated for standard Zircaloy-4 materials. The differences between the models were attributed to empirical variables such as the frequency factor (k 2 , B) and the activation energy (Q 2 ) in Tables I, II, and III, which were calibrated with other experimental/plant data.

    A survey was carried out on respiratory symptoms and skin prick response to common allergens, storage mite and occupational allergens. Among 178 symptomatics bakers and pastry workers from small businesses in western France, only 65 people underwent skin prick and specific-IgE. 12 (18%) workers were skin positive to at least one common or occupational allergens. The more often skin positive were D. Ptero. mite 36 (57%); Alpha amylase 23 (35%); wheat flour 17 (26%); saccharomyces cerevisiae 16 (25%); Ephestia 15 (24%). The sensitivity of skin test was better than specific IgE for D. Ptero. Mite 36 (57%); and Alpha amylase 23 (35%). The sensitivity of specific IgE was better than skin test for wheat flour 26 (45%) and rye flour 23 (40%). Occurrence of skin positive to occupational allergen among symptomatics with rhinitis and asthma is much more frequent in workers with skin positive to common allergens (40/36) than in workers with skin negative (8/20). Atopy must be regarded as an important predisposing factor for skin sensitisation to occupational allergens. We conclude in the necessity of a standardised allergologic exploration to be done in symptomatics bakers.

    Objective: To investigate the safety and feasibility of endovascular stent angioplasty in treating symptomatic stenosis of middle cerebral artery. Methods: Endovascular angioplasty with coronary stents was performed in 27 patients with symptomatic stenosis of middle cerebral artery. The clinical results were reviewed and analyzed. Results: Of the total 27 patients, successful placement of the coronary stents was achieved in 24. Angiography immediately after the procedure showed that the stenotic degree of the diseased artery was markedly decreased from preoperative (80 ± 19)% to postoperative (8 ±4)%, the improvement was very obvious. Percutaneous transcatheter angioplasty had to be employed in two cases because of the failure of stent placement. A mean follow-up period of 18 months was carried out. During the following up period no transient cerebral ischemia attack occurred in 25 patients and no newly-developed cerebral infarction in region fed by the responsible vessels occurred either.Re-irrigation cerebral hemorrhage was seen in one patient, which occurred three hours after the placement of the stent. In one case the placed stent fell off and immigrated into the siphon of internal carotid artery, and the displaced stent was took out later with a catching apparatus. In another case re-stenosis occurred six months after the stenting. Conclusion: Percutaneous endovascular stent angioplasty is a safe and effective treatment for symptomatic stenosis of middle cerebral artery, although its long-term results need to be further evaluated.

    Full Text Available In Bihar, India, high maternal anemia prevalence and low iron and folic acid supplement (IFA receipt and consumption have continued over time despite universal IFA distribution and counseling during pregnancy.To examine individual and facility-level determinants of IFA receipt and consumption among pregnant women in rural Bihar, India.Using District Level Household Survey (2007-08 data, multilevel modeling was conducted to examine the determinants of two outcomes: IFA receipt (any IFA receipt vs. none and IFA consumption (≥90 days vs. <90 days. Individual-level and facility-level factors were included. Factor analysis was utilized to construct antenatal care (ANC quality and health sub-center (HSC capacity variables.Overall, 37% of women received any IFA during their last pregnancy. Of those, 24% consumed IFA for 90 or more days. Women were more likely to receive any IFA when they received additional ANC services and counseling, and attended ANC earlier and more frequently. Significant interactions were found between ANC quality factors (odds ratio (OR: 0.37, 95% confidence interval (CI: 0.25, 0.56 and between ANC services and ANC timing and frequency (OR: 0.68, 95% CI: 0.56, 0.82. No HSC factors were significantly associated with IFA receipt. Women were more likely to consume IFA for ≥90 days if they attended at least 4 ANC check-ups and received more ANC services. IFA supply at the HSC (OR: 1.37, 95% CI: 1.04, 1.82 was also significantly associated with IFA consumption.Our findings indicate that individual and ANC factors (timing, frequency, and quality play a key role in facilitating IFA receipt and consumption. Although HSC capacity factors were not found to influence our outcomes, significant variation at the facility level indicates unmeasured factors that could be important to address in future interventions.

    Urinary tract infections, including pyelonephritis, are serious complications that may lead to significant maternal and neonatal morbidity and mortality. There is a large number of drugs, and combination of them, available to treat urinary tract infections, most of them tested in non-pregnant women. Attempts to define the optimal antibiotic regimen for pregnancy have, therefore, been problematic. The objective of this review was to determine, from the best available evidence from randomised controlled trials, which agent is the most effective for the treatment of symptomatic urinary tract infections during pregnancy in terms of cure rates, recurrent infection, incidence of preterm delivery and premature rupture of membranes, admission to neonatal intensive care unit, need for change of antibiotic, and incidence of prolonged pyrexia. We searched the Cochrane Pregnancy and Childbirth Group Trials Register (November 2009) and reference lists of articles. We considered all trials where the intention was to allocate participants randomly to one of at least two alternative treatments for any symptomatic urinary tract infection. Both review authors assessed trial quality and extracted data. We included 10 studies, recruiting a total of 1125 pregnant women. In most of the comparisons there were no significant differences between the treatments under study with regard to cure rates, recurrent infection, incidence of preterm delivery, admission to neonatal intensive care unit, need for change of antibiotic and incidence of prolonged pyrexia. When cefuroxime and cephradine were compared, there were better cure rates (29/49 versus 41/52) and fewer recurrences (20/49 versus 11/52) in the cefuroxime group. There was only one other statistically significant difference when comparing outpatient versus inpatient treatment. Gestational age at birth was greater in women from the outpatient group (38.86 versus 37.21), while birthweight was on average greater in the inpatient group

However, the role of symptomatic menopausal transition in diagnostic conversion from major depression to bipolar disorder was still unknown. Using the Taiwan National Health Insurance Research Database, 50,273 midlife women aged between 40 and 60 years in 2002∼2008 with major depression were enrolled in our study and divided into two subgroups based on the presence (n = 21,120) or absence (n = 29,153) of symptomatic menopausal transition. Subjects who had subsequent bipolar disorder during the follow-up were identified. Midlife women with major depression and symptomatic menopausal transition had a higher incidence of the diagnostic conversion to bipolar disorder (7.3 vs. 6.6%, p = 0.003) than those with major depression alone. Cox regression analysis after adjusting for demographic data and psychiatric comorbidities further showed that symptomatic menopausal transition was associated with an increased risk of developing bipolar disorder (HR 1.14, 95% CI 1.07∼1.23) among midlife women with major depression. Sensitivity test after excluding the 1-year and 3-year observation exhibited the consistent findings (HR 1.18, 95% CI 1.09∼1.28; HR 1.20, 95% CI 1.08∼1.34). Midlife women with the dual diagnoses of major depression and symptomatic menopausal transition had an increased risk of the diagnostic conversion to bipolar disorder compared to those with major depression alone. Further studies may be required to investigate the underlying mechanisms among menopausal transition and the diagnostic conversion from major depression to bipolar disorder.

    The pathogenesis and symptomatics of the acute radiation syndrome are discussed. Diagnosis and therapy would be impossible without detailed knowledge in these fields. The concept of acute radiation syndrome is explained, and a pathophysiological analysis of the various forms of radiation syndrome - haematological, intestinal and affecting the central nervous system is attempted. The developments in the diagnosis and therapy of acute radiation syndrome since its first description - 35 years ago - are reviewed. Today, whole-body doses of 100 rd and more can be treated by radiotherapy. (orig./MG) [de

    Background: During 2001 to 2005, 1-year breast cancer survival was low in ethnically diverse East London. We hypothesised that this was due to low breast cancer awareness and barriers to symptomatic presentation, leading to late stage at diagnosis in women from ethnic minorities. We examined ethnic differences in breast cancer awareness and barriers to symptomatic presentation in East London. Methods: We carried out a population-based survey of 1515 women aged 30+ using the Cancer Research UK Breast Cancer Awareness Measure. We analysed the data using logistic regression adjusting for age group and level of deprivation. Results: South Asian and black women had lower breast cancer awareness than white women. South Asian women, but not black women, reported more emotional barriers to seeking medical help than white women. White women were more likely than non-white women to report worry about wasting the doctor's time as a barrier to symptomatic presentation. Conclusion: Interventions to promote early presentation of breast cancer for South Asian and black women should promote knowledge of symptoms and skills to detect changes, and tackle emotional barriers to symptomatic presentation and for white women tackle the idea that going to the doctor to discuss a breast symptom will waste the doctor's time.

    Introduction. Transmission of cytomegalovirus (CMV) via breast milk can lead to severe acute illness in very low-birth-weight (VLBW) preterm infants. Although the majority of CMV-seropositive women shed CMV in milk, symptomatic postnatal infection of VLBW infants occurs infrequently, suggesting that virologic or immunologic factors in milk may be associated with the risk and severity of postnatal CMV infection. Methods. We investigated the magnitude of CMV-specific cellular and humoral immune responses in milk of 30 seropositive mothers of VLWB preterm infants and assessed their relationship to milk CMV load and symptomatic CMV transmission. Results. Milk immunoglobulin G (IgG) avidity was inversely correlated to milk CMV load (r = −0.47; P = .009). However, milk CMV load and CMV-specific cellular and humoral immune responses were similar in mothers of VLBW infants with and those without symptomatic postnatal CMV infection. Conclusions. Similar immunologic parameters in milk of CMV-seropositive mothers of VLBW infants with and without symptomatic postnatal CMV infection indicate that screening milk by these parameters may not predict disease risk. However, the inverse correlation between milk CMV IgG avidity and CMV load may suggest that enhancement of maternal CMV-specific IgG responses could aid in reduction of CMV shedding into breast milk.

    Context Since HSV-2 antibody tests have become commercially available, an increasing number of persons learn that they have genital herpes through serologic testing. The course of natural history of HSV-2 in asymptomatic, seropositive persons is uncertain. Objective To evaluate the virologic and clinical course of HSV genital shedding among participants with symptomatic and asymptomatic HSV-2 infection. Design, Setting and Participants Cohort of 498 immunocompetent HSV-2 seropositive persons enrolled in prospective studies of genital HSV shedding at the University of Washington Virology Research Clinic, Seattle, Washington, and Westover Heights Clinic in Portland, Oregon, between 1992 and 2008. Each participant obtained daily self-collected swabs of genital secretions for ≥ 30 days. Main Outcome Measurement The rate of viral shedding measured by quantitative real-time fluorescence polymerase chain reaction (PCR) for HSV DNA from genital swabs. Results HSV was detected on 4,753 of 23,683 days (20.1%; 95% CI, 18.3 to 22.0) in persons with symptomatic genital HSV-2 infection compared with 519 of 5,070 days (10.2%; 95% CI, 7.7 to 13.6) in persons with asymptomatic infection, pgenital viral shedding among persons with symptomatic genital HSV-2 infection compared with 85 of 519 days (16.4%; 95% CI, 11.2 to 23.9) among persons with asymptomatic infection, pgenital tract less frequently than persons with symptomatic infection, but much of the difference is attributable to less frequent genital lesions, as lesions are accompanied by frequent viral shedding.

Higher BTU levels significantly correlated with symptoms, but a normal BTU could not exclude a specific pathology after THA. A threshold of BTU in SPECT/CT was identified to distinguish between symptomatic and asymptomatic patients after THA. (orig.)

    To evaluate the efficacy of a collagen-fibrin patch for the prevention of symptomatic lymphoceles after pelvic lymphadenectomy in women with gynecologic malignancies. In a multicenter, randomized, clinical trial, 164 women with pelvic lymphadenectomy were allocated either to bilateral pelvic application of two collagen-fibrin patches or no intervention. Main outcome was efficacy, defined as reduction of symptomatic lymphocele rate diagnosed within four weeks after surgery. Secondary outcomes were asymptomatic lymphoceles and subsequent interventions. Sample size was based on the assumption that application of a collagen-fibrin patch reduces the prevalence of symptomatic lymphoceles by at least 66%. The study was single-blinded, i.e., patients and primary outcome assessors, but not surgeons, were blinded to the treatment allocation. A total of 75 women were randomized to the intervention and 89 to the control group. All women received the allocated intervention. In total, 42 (27.4%) lymphoceles and 8 (5.2%) symptomatic lymphoceles were observed. Symptomatic lymphoceles were observed in 5/68 (7.4%) women in the intervention group and 3/85 (3.5%) women in the control group (p = 0.47). Asymptomatic lymphoceles were observed in 16 (23.5%) women in the intervention group compared to 18 (21.2%) in the control group (p = 0.85). In a multivariate logistic regression model, no independent risk factor for the development of a symptomatic lymphocele was ascertained. Intraoperative application of collagen-fibrin patches to the pelvic side walls does not reduce the incidence of symptomatic lymphoceles in women with gynecologic malignancies undergoing pelvic lymphadenectomy.

    Neuropsychological deficits and severity of initial psychopathology have been repeatedly associated with poor symptomatic outcomes in schizophrenia. The role of higher-order cognitive biases on symptomatic outcomes of the disorder has not yet been investigated. The present study aimed to assess the contribution of cognitive biases, psychopathology and neuropsychological deficits on the probability of achieving early symptomatic remission after a psychotic episode in patients with schizophrenia. Participants were 79 patients with a DSM-IV diagnosis of schizophrenia or schizoaffective disorder undergoing an acute psychotic episode, and 25 healthy controls. According to psychopathology assessments, patients were split into those who had achieved remission after an average follow-up interval of 7 months, and those who had not (NR). Patients who achieved remission exhibited higher premorbid IQ and better performance on the TMT-B, as well as lower baseline positive, disorganized and distress symptoms than NR patients. TMT-B performance and positive symptoms at baseline were the best predictors of remission. Cognitive biases and negative symptoms were not associated with later remission. The findings highlight the significance of initial symptom severity for at least short-term symptomatic outcomes and, thus, the importance of adequate symptomatic treatment and prevention of psychotic outbreaks in patients. © 2013 Elsevier Ireland Ltd.

    The World Health Organization recommends iron and folic acid (IFA) supplementation for pregnant women. The high prevalence of anaemia among pregnant women in Niger warrants better understanding of the utilization of antenatal care (ANC) and IFA. We aimed to assess the prevalence of and factors associated with ANC coverage and adherence to IFA recommendation among pregnant women. Pregnant women (n = 923) from 64 randomly selected villages within the catchment area of 12 health centres were interviewed during a baseline household survey in Zinder, Niger. ANC and IFA coverage were 60.1% and 43.6%, respectively. Only 71.7% of women who attended ANC received IFA. Of the 401 women who reportedly received any IFA supplements, 99.3% had attended any ANC during their current pregnancy and 68.6% reported adherence to recommended IFA supplementation (i.e., consumed IFA every day in the previous week). Women with gestational age ≥27 weeks were more likely to have attended ANC than women with gestational age ANC were more likely to attend ANC (OR: 1.48, 95% CI [1.03, 2.11]) and adhere to IFA recommendations (OR: 1.80, 95% CI [1.04, 3.13]) compared to those who did not receive any advice. ANC attendance is crucial to ensure distribution of IFA supplementation among pregnant women in Zinder. Interventions to improve ANC and IFA adherence will require promotion of early ANC, ensure availability of IFA at ANC, and involve husbands in ANC. © 2018 John Wiley & Sons Ltd.

    Rotator cuff tears are a common cause of shoulder pain. There is an absence of information about symptomatic rotator cuffs from the patients' perspective; this limits the information clinicians can share with patients and the information that patients can access via sources such as the internet. This study describes the experiences of people with a symptomatic rotator cuff, their symptoms, the impact upon their daily lives and the coping strategies utilised by study participants. An interpretive phenomenological analysis approach was used. 20 participants of the UKUFF trial (The United Kingdom Rotator Cuff Surgery Trial) agreed to participate in in-depth semi-structured interviews about their experiences about living with a symptomatic rotator cuff tear. Interviews were digitally recorded and fully transcribed. Field notes, memos and a reflexive diary were used. Data was coded in accordance with interpretive phenomenological analysis. Peer review, code-recode audits and constant comparison of data, codes and categories occurred throughout. The majority of patients described intense pain and severely disturbed sleep. Limited movement and reduced muscle strength were described by some participants. The predominantly adverse impact that a symptomatic rotator cuff tear had upon activities of daily living, leisure activities and occupation was described. The emotional and financial impact and impact upon caring roles were detailed. Coping strategies included attempting to carry on as normally as possible, accepting their condition, using their other arm, using analgesics, aids and adaptions. Clinicians need to appreciate and understand the intensity and shocking nature of pain that may be experienced by participants with known rotator cuff tears and understand the detrimental impact tears can have upon all areas of patient's lives. Clinicians also need to be aware of the potential emotional impact caused by cuff tears and to ensure that patients needing help for

    In spite of a few shortcomings such as over diagnosis and over treatment, syndromic management is a recommended practice in India for sexually transmitted infections (STIs). This study tries to find out the efficacy of syndromic management measured as symptomatic improvement in females with vaginal discharge syndrome. The objective of the study is to find out the effectiveness of syndromic management in terms of symptomatic improvement among females with vaginal discharge syndrome. A longitudinal study was conducted in Gynecology Department of Tertiary Care Hospital including 180 symptomatic females having vaginal discharge syndrome. Demographic profile, presenting complaints, menstrual history, obstetric history, partner history, and contraceptive history were noted. This was followed by clinical examination and specimen collection for laboratory tests and blood tests to find out type of STI including viral STI such as human immunodeficiency virus (HIV), herpes simplex virus (HSV), and hepatitis B surface antigen (HBsAg). Treatment was given according to syndromic management on the same day. All the participants were asked to come for follow-up after 15 days and their improvement in symptoms was noted as complete improvement, some improvement or no improvement on a five point scale. 63.9% cases showed complete improvement, while 36.1% showed some improvement. None of the patients was without any improvement. Vaginal discharge syndrome was most common between 20 and 30 years (43.4%), and 67.8% of symptomatic females with vaginal discharge syndrome belonged to the lower socioeconomic group. HSV infection was the most common (15%) associated viral infection with vaginal discharge syndrome, while hepatitis B infection was the least common (0.5%). HIV was reactive in 2.8% cases only. Syndromic management was found to be effective in relieving symptoms in most of the cases of vaginal discharge syndrome.

    Background The risk of recurrent stroke among patients with symptomatic carotid near-occlusion is not well established, and management of the condition remains controversial. Symptomatic carotid near-occlusion with full collapse has been identified as a strong predictor of early recurrence. We aimed to analyze the 90-day risk of recurrent ipsilateral ischemic stroke in medically treated patients with symptomatic carotid near-occlusion. Methods We performed a multicenter, nationwide, prospective study from January 2010 to May 2016. Patients with angiography-confirmed symptomatic carotid near-occlusion were included. The primary endpoint was ipsilateral ischemic stroke or transient ischemic attack (TIA) within 90 days after the presenting event. For this analysis, patients who underwent revascularization within 90 days after stroke were excluded. Results The study population comprised 141 patients from 17 Spanish centers; 83 patients were treated medically. Primary endpoint occurred in eight patients, resulting in a cumulative rate of 10.6% (95% CI, 3.7-17.5). Previous history of stroke or transient ischemic attack was identified as an independent predictor for recurrence in the multivariate Cox regression analysis (HR, 4.37 [95% CI, 1.05-18.18]; p = 0.043), while the presence of full collapse was not associated with an increased risk (HR, 0.81 [95% CI, 0.17-3.92]; p = 0.793). The risk of recurrence was also not affected by the presence of significant stenosis or occlusion of the contralateral carotid artery, or by the collateral circulation. Conclusions Patients with symptomatic carotid near-occlusion seem to have an increased risk of early ipsilateral recurrent stroke. Our results contrast with the low risk of symptomatic carotid near-occlusion reported to date. Full collapse did not increase the risk of recurrent stroke in our study.

    Background: Both primary angioplasty alone and angioplasty with a self-expanding stent have been compared in non-randomized concurrent clinical studies that suggest equivalent results. However, there is no randomized trial that has compared the two procedures in patients with symptomatic high grade intracranial stenosis. Objective: The primary aim of the randomized trial was to compare the clinical and angiographic efficacy of primary angioplasty and angioplasty followed by stent placement in preventing restenosis, stroke, requirement for second treatment, and death in patients with symptomatic intracranial stenosis. Methods: The study prospectively evaluated efficacy and safety of the two existing neurointerventional techniques for treatment of moderate intracranial stenosis (stenosis ≥ 50%) with documented failure of medical treatment or severe stenosis (≥70%) with or without failure of medical treatment. Results: A total of 18 patients were recruited in the study (mean age [±SD] was 64.7 ± 15.1 years); out of these, 12 were men. Of these 18, 10 were treated with primary angioplasty and 8 were treated with angioplasty followed by self-expanding stent. The technical success rates of intracranial angioplasty and stent placements defined as ability to achieve <30% residual stenosis when assessed by immediate post-procedure angiography was 5 of 10 and 5 of 8 patients, respectively. The total fluoroscopic time (mean [±SD]) was lower in patients undergoing primary angioplasty 37 [±11] min versus those undergoing angioplasty followed by self-expanding stent 42 [±15] min, P = 0.4321. The stroke and death rate within 1 month was very low in both patient groups (1 of 10 versus 0 of 8 patients). One patient randomized to stent placement continued to have recurrent ischemic symptoms requiring another angioplasty in the vertebral artery on post-procedure Day 2. Conclusions: The trial suggests that a randomized trial comparing primary angioplasty to angioplasty

    The aim of this study is to analyse the symptomatic response of elderly people to heat burden and indoor air quality exposure, and to create an index, the basis on which healthcare workers could react and prevent heat-related illnesses when the first symptoms appear. The impact of the indoor thermal environment was studied with regards to Humidex and indoor air quality by CO2 concentrations on elderly people's symptomatic response. It was a natural experiment in which two different groups of elderly people (>65 years) were observed: the first group had a diagnosed cardiovascular disease, and the second group did not have the disease. The results show that the expression and aggravation of symptoms are related to an increase of heat burden and low indoor air quality. The symptoms under analysis do not have the same frequency distribution of intensity and, therefore, cannot be interpreted as a single universal symptom index. Instead, two indices must be created separately for both general and specific symptoms. Healthcare workers should be educated about the interactive influences of the thermal environment and the air quality on health. Unsuitable conditions could be ascertained by the nursing home occupants' symptomatic response. Copyright© by the National Institute of Public Health, Prague 2017

    To analyze the immediate and midterm success of stenting of mesenteric arteries by a monorail technique in patients with chronic mesenteric ischemia. In this prospective case series, 19 patients (11 male, 8 female; mean age, 62.9 +/- 10.4 y; range, 36-82 y) with 23 symptomatic stenoses of mesenteric arteries were treated with stent placement by a monorail technique in a radiologic intervention center over a period of 4.5 years. Clinical examinations and duplex sonography were used to evaluate the stents' patency and clinical success. Kaplan-Meier graphs were calculated to analyze the patency and freedom-from-symptom rate. Initial technical success rate was 22/23 (96%). Mean follow-up was 17 months (range, 1-58 mo). Primary patency and primary clinical success rates were 82% and 78%, respectively. According to Kaplan-Meier tables, the patency rates were 96%, 87%, 76%, and 61% at 0, 1, 15, and 24 months, respectively, and the freedom-from-symptom rates were 95%, 90%, 72%, and 54% at 0, 1, 24, and 30 months, respectively. No peri-interventional complications occurred. Two patients died of cardiac failure in the hospital within 30 days after intervention; deaths were not related to the intervention. Stent placement by a monorail technique in mesenteric arteries is an effective and safe treatment for symptomatic stenoses in patients with chronic mesenteric ischemia after a mean follow-up of 17 months.

    Infantile flexible flatfoot does not require treatment in most cases. Symptomatic flexible flat feet are treated orthopaedically and surgery is only indicated when orthosis fails. Cases who underwent surgical treatment with the stop screw technique at the 12 de Octubre Hospital between 1995 and 2002 are reported. Patient progress is also analysed. Six angles are measured on the x-ray prior to surgery and those same x-ray angles are measured again before material extraction. They are then compared to see if the correction achieved is statistically significant. A more reduced sample is currently being assessed with the same radiological measurements and two clinical assessment scales: Lickert, and Smith and Millar. The latest x-rays are analysed by two radiologists to determine if there is subtalar arthrosis. In the short term, statistically significant differences are observed in all angles. The comparison between the post-surgery angles and the current angles does not show differences, except for the Giannestras angle, which has statistically significantly worsened. Clinical results and patient satisfaction is good. Incipient subtalar arthrosis is present in 68.5% of current patient x-rays. Stop screw method is a cheap, simple and effective technique to correct symptomatic flexible flatfoot that has not improved with conservative treatment. This technique provides short-term foot correction which can be maintained over time. Copyright © 2015 SECOT. Published by Elsevier Espana. All rights reserved.

    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.

    To report the outcomes of rib reconstruction after painful nonunion. Retrospective case series. Level I trauma center. Between November 2007 and May 2013, 10 patients who presented with 16 rib nonunions and disabling pain were treated with reconstruction of their nonunited rib fractures. Rib nonunion reconstruction predominately with iliac crest bone graft and a tension band plate with a locked precontoured plating system for ribs. Demographic data, mechanism of injury, and number of rib nonunions were recorded. Operative procedure, length of follow-up, complications, Short Form Survey 36, and a patient questionnaire were also captured and documented. Eight of the 10 patients sustained their original fractures from a fall. Outcomes were available for the 10 patients at a mean follow-up of up of 18.6 months (range, 3-46 months). All 16 ribs went on to union with a mean time from reconstruction to union of 14.7 weeks (range, 12-24 weeks). At final follow-up, the mean mental and physical component Short Form Survey 36 scores were 54.4 and 43.5, respectively. Eight of the 10 patients were able to return to work and/or previous activities without limitations. Complications included 1 wound infection that resolved after irrigation and debridement with adjunctive antibiotics. One symptomatic implant was removed. Ten patients with 16 symptomatic rib nonunions were reconstructed using autologous bone graft and implant/mesh fixation manifesting in successful union with improved patient function and a low rate of complications.

    Full Text Available Sensitivity of field tests (AgriStrip  and Immunochromato, DAS-ELISA, two step RT-PCR and real-time RT-PCR for Plum pox virus (PPV detection was tested in various tissues of apricot, peach, plum and damson plum trees infected with isolates belonging to PPV-D, PPV-M or PPV-Rec, the three strains present in Slovenia. Flowers of apricot and plum in full bloom proved to be a very good source for detection of PPV. PPV could be detected with all tested techniques in symptomatic parts of leaves in May and with one exception even in the beginning of August, but it was not detected in asymptomatic leaves using field tests, DAS-ELISA and partly also molecular techniques. PPV was detected only in some of the samples of asymptomatic parts of the leaves with symptoms and of stalks by field tests and DAS-ELISA. Infections were not detected in buds in August using field tests or DAS-ELISA. Field tests are useful for confirmation of the PPV infection in symptomatic leaves, but in tissues without symptoms DAS-ELISA should be combined or replaced by molecular techniques.

Objectives: To study the â€"Coverage level for immunization, antenatal care and IFA tablets â€"Relationship of caste and education with the coverage levels. â€"Place and persons conducting deliveries. Study design: Cross-sectional. Setting: Both in rural and urban areas of Bihar. Participants: 375 mothers having children up to one year of age selected by a stratified random sampling technique developed by IRMS Delhi. Study variables: Immunisation status, antenatal care, Use of IFA tabs, Education of the female, Education of husband, place and person conducting the delivery. Statistical analysis: Proportions. Results: Overall immunization coverage was 42% for pregnant females. Coverage was high (60% in urban areas compared to rural areas (40%. Coverage was low among females from SC/ST category, also when females and their husbands were illiterates. Similar trend was observed for antenatal care and IFA tabs. 90% deliveries took place at home and were mainly attended by village dais. Majority of mothers received immunization from some. Govt. agency lack of, awareness and lack of motivation were more commonly found as reasons for non-immunisation among SC/ST as compared to others. Lack of awareness was also found as a common reason for non-immunisation among illiterate females.

    Renal oncocytomas are benign tumours, often asymptomatic, and picked incidentally on radiological imaging. We present a case report of a symptomatic giant renal oncocytoma in a 61-year old man having lower back\\/right flank pain. A large right renal mass was identified on abdominal CT scan. Radiological features were not sufficient to differentiate this lesion from renal cancer. Right radical nephrectomy was performed. Typical features of oncocytoma, without evidence of malignancy, were seen on histological examination of the specimen. In this report, we discuss literature review of radiological, genetic, and pathological characteristics of renal oncocytoma.

    The intestinal endometriosis in need of treatment is a rare case in the surgical department. Preoperative diagnosis is very difficult and in any case must be based on histologic findings; endoscopy-guided biopsy very frequently yields negative results. Dual-contrast scanning of the colon still is a major examination method, but the findings make it difficult to rule out malignomas. Cyclic, recurrent abdominal complaints reported in the case history strongly indicate the possibility of endometriosis. Typing can be done in general only after surgery. The article reports the clinical and diagnostic parameters of a symptomatic endometriosis of the colon. (orig.) [de

    2008-08-05

    Pulmonary siderosis secondary to the inhalation of iron compounds is a rare condition which, despite striking radiological and histopathological features, has not traditionally been associated with symptoms or functional impairment. Although not the first of its kind, we present an unusual case of pulmonary siderosis with symptomatic respiratory disease, most likely secondary to associated fibrosis. A 66-year-old Caucasian man was referred to the outpatient clinic with a 2-year history of exertional breathlessness. He had worked as an engineer for 20 years where he did a significant amount of welding but always wore a face shield. Clinical, radiological and histological features were consistent with a diagnosis of pulmonary siderosis, with associated fibrosis, most likely related to his occupational welding history. Our report illustrates that symptomatic respiratory disease due to mild peribronchiolar fibrosis can occur with pulmonary siderosis despite wearing a mask. Furthermore, it reinforces the need for all clinicians to compile a detailed occupational history in individuals presenting with breathlessness.

    Background: To evaluate the safety and efficacy of stent angioplasty in the treatment of symptomatic arteriosclerotic stenoses of the proximal vertebral artery (VA). Methods: Thirty-eight symptomatic stenoses of the vertebral origin were treated with flexible balloon-expandable coronary stents. Angiographic and clinical follow-up examinations were obtained in 26 patients at a mean of 11 months. Results: The immediate post-procedural angiographic results showed no residual stenosis in 33 vessels and mild residual stenoses in five vessels. Periprocedurally, there were two asymptomatic technical complications and one TIA. During follow-up re-stenosis could be detected in 10 cases (36%), and vessel occlusions in two patients. Two stents were broken. One of the restenosis caused a TIA within the follow-up period. Conclusions: Flexible balloon-expandable coronary stents proved to be save and effective in preventing vertebrobasilar stroke but were incapable to preserve the proximal vertebral artery lumen. For the VA origine an adequate stent, self-expanding, bioresorbable, or drug-eluting has to be found.

    Previous studies have quantified bacterial loads of Neisseria gonorrhoeae in the pharynx and rectum of men but not the urethra. We quantified the bacterial load of N. gonorrhoeae in men with symptomatic and asymptomatic urethral gonorrhoea infections. Consecutive men diagnosed with urethral gonorrhoea by Aptima Combo 2 testing of urine at the Melbourne Sexual Health Centre between March and July 2016 were eligible for the study: symptomatic men with purulent urethral discharge and asymptomatic men with no urethral symptoms. The gonococcal bacterial load in both groups was measured by urethral swab using a standardised collection method and real-time quantitative PCR targeting the opa gene. Twenty men were recruited into the study: 16 had purulent urethral discharge and 4 had asymptomatic urethral gonorrhoea. The median gonococcal bacterial load was significantly higher among symptomatic men (3.7×10 6 copies per swab, IQR 2.5×10 6 -4.7×10 6 ) compared with asymptomatic men (2.0×10 5 copies per swab, IQR 2.7×10 4 -4.5×10 5 ) (p=0.002). Gonococcal loads in men with urethral discharge were higher than loads seen with asymptomatic urethral gonorrhoea and loads seen in asymptomatic pharyngeal and rectal gonorrhoea infections in previous studies.

    Uncomplicated urinary tract infections (UTIs) are the most common bacterial infections among women presenting to primary care causing rapidly increasing strains of resistant bacteria to the growing antibiotic industry. Restricting antibiotics to necessary indications is the only solution. The objectives of the study were to compare the efficacy of symptomatic treatment vs antibiotic in patients with uncomplicated UTI, in terms of individual symptom score, i.e., frequency, urgency, dysuria, supra pubic pain scores and total symptoms scores. Methods: A randomized control trial (RCT) in 100 women (15-50 years) with symptoms of urinary frequency, urgency, dysuria and pain supra pubic region, associated with uncomplicated UTI, at Urology department, AMI, Abbottabad. Two treatment strategies were compared in uncomplicated UTI patient). Patients were randomized to antibiotic or symptomatic treatment groups on consecutive non-probability basis (50 in each group) given for 05 days. Efficacy of medications was assessed by comparing pre and post treatment symptom scores along with the post treatment scores of both groups compared to see statistical significance of difference by independent samples t-test. Results: There was a statistically significant difference in symptoms improvement in both treatment arms of all scores, i.e., p-value=0.000. Whereas only dysuria score was able to show a statistically significance of difference in post Rx scores comparison of both groups, p-value=0.004. Conclusions: Symptomatic treatment is not inferior to antibiotic treatment when proper patient selection is undertaken, resulting in decreased need for unnecessary antibiotics use. (author)

    Wingspan stenting for the treatment of complex intracranial atherosclerotic stenosis (ICAS), i.e., that involving tortuous vascular pathways, long (>15 mm) lesions or arterial bifurcations, has a relatively high risk of complications. This retrospective study assessed the safety and efficacy of undersized balloon angioplasty followed by deployment of the more flexible Enterprise stent for the treatment of complex symptomatic ICAS. Forty-four patients on combined antiplatelet therapy and intensive risk factor management and a symptomatic 70-99% stenosis of a major intracranial artery in complex settings that was treated with balloon angioplasty and Enterprise stent deployment between July 2009 and August 2013 were enrolled. Primary outcome was occurrence of ischemic or hemorrhagic stroke or death within 30 days after intervention. Secondary outcomes included procedural success (defined as achievement of 50% in-stent restenosis after mean 22 months follow-up. In this retrospective, single-center experience, undersized balloon angioplasty followed by Enterprise stent deployment appears technically feasible with a relatively low rate of complications for the treatment of complex symptomatic ICAS. Prospective, multicenter, randomized controlled trials against optimal medical management are warranted.

    Simple liver cysts are congenital with a prevalence of 2.5%-4.25%. Imaging, whether by US, CT or MRI,is accurate in distinguishing simple cysts from other etiologies, including parasitic, neoplastic, duct-related,and traumatic cysts. Symptomatic simple liver cysts are rare, and the true frequency of symptoms is not known.Symptomatic simple liver cysts are predominantly large (> 4 cm), right-sided, and more common in women and older patients. The vast majority of simple hepatic cysts require no treatment or follow-up, though large cysts (> 4 cm) may be followed initially with serial imaging to ensure stability. Attribution of symptoms to a large simple cyst should be undertaken with caution, after alternative diagnoses have been excluded. Aspiration may be performed to test whether symptoms are due to the cyst; however, cyst recurrence should be expected.Limited experience with both laparoscopic deroofing and aspiration, followed by instillation of a sclerosing agent has demonstrated promising results for the treatment of symptomatic cysts. Here, we describe a patient with a large, symptomatic, simple liver cyst who experienced complete resolution of symptoms following cyst drainage and alcohol ablation, and we present a comprehensive review of the literature.

    Flatfoot deformity is a lever arm disease that incurs kinetic inefficiency during gait. The purpose of this study was to measure the degree of kinetic inefficiency by comparing the gait analysis data of a flatfoot group with a normal control group. The patient group consisted of 26 children (21 males and 5 females) with symptomatic flatfoot. They were examined with gait analysis between May 2005 and February 2014. Exclusion criteria were patients with secondary flatfoot caused by neuromuscular disorders, tarsal coalition, vertical talus, or others. Patients' mean age was 9.5 years (range, 7 to 13 years). The gait analysis data of the study group and the normal control group were compared. The mean vertical ground reaction force (GRF) in the push-off phase was 0.99 for the patient group and 1.15 for the control group ( p push-off phase was 0.89 for the patient group and 1.27 for the control group ( p push-off phase was 1.38 for the patient group and 2.52 for the control group ( p push-off phase during gait. Symptomatic flatfeet had a moment inefficiency of 30% and power inefficiency of 45% during gait compared to feet with preserved medial longitudinal arches.

    In 19 cases with newly diagnosed symptomatic West syndrome, we assessed interictal regional cerebral blood flow (rCBF) before ACTH therapy with single photon emission computed tomography (SPECT). Based on the SPECT findings, we divided these cases into 3 groups: normal rCBF (Group A, 7 cases), abnormal rCBF corresponding to cerebral lesions on MRI and CT (Group B, 6 cases), and abnormal rCBF in areas different from lesions on MRI and CT (Group C, 6 cases). We compared clinical features, response to initial treatment, and short-term outcome among these 3 groups. No significant differences were found in clinical characteristics (sex, age of onset, prior seizures before onset of spasms, EEG findings). Four cases in Group B (67%) and 5 in Group C (83%) showed complete cessation of spasms after initial treatment (high dose vitamin B{sub 6}{yields}zonisamide{yields}ACTH therapy), while in Group A only 2 patients (29%, p>0.05; compared to Group B or Group C) responded. Although not statistically significant, short-term prognosis (both seizures and development) after a mean follow-up of 2 years and 8 months was also worst in Group A. Our results suggest that normal SPECT findings may be predictive of unfavorable prognosis in infants with symptomatic West syndrome. (author)

    Management of symptomatic pancreatic anastomotic insufficiency after pancreas head resection remains controversial. Completion pancreatectomy as one frequently performed option is associated with poor prognosis. During a 4-year period, a two-step strategy was applied in four consecutive patients suffering from pancreatic anastomotic insufficiency refractory to conservative management after a pancreas head resection. In the first step, sepsis was overbridged by meticulous debridement and resection of the pancreaticojejunostomy, leaving the biliary anastomosis untouched, and selective drainage of the pancreatic duct as well as the peripancreatic area. In the second step, after recovery, the procedure was completed with a novel pancreaticojejunostomy. The surgical procedure was completed in three patients after a mean of 164 (range: 112-213) days. One patient died from cardiac arrest 54 days after the reoperation with resolved abdominal sepsis. No pancreatic anastomotic insufficiency occurred after the new pancreaticojejunostomy had been performed. Three patients are alive and tumor-free with normal exocrine and endocrine pancreatic function after a mean follow-up of 20.3 (3-38) months following the definitive reconstruction. The two-step pancreas-preserving strategy can be used as an alternative to completion pancreatectomy for patients suffering from severe pancreatic anastomotic insufficiency.

    Data on image quality, compression and radiation dose were collected from symptomatic breast units within the Republic of Ireland. Quantitative and qualitative data were analysed using SPSS. Recommendations of mean glandular dose (MGD) diagnostic reference levels were made at various levels for film-screen and full field digital mammography units to match levels published worldwide. MGDs received by symptomatic breast patients within Ireland are higher than those received in the all-digital Irish Breast Screening service; 55-65 mm breast: 1.75 mGy (screening) vs. 2.4 mGy (symptomatic) at the 95. percentile; various reasons are proposed for the differences. MGDs achieved in the screening service may be lower because of the exacting requirements for radiographer training, characteristics of the patients and equipment quality assurance levels. More precise imaging guidelines, standards and training of symptomatic radiographers performing mammography are suggested to remediate MGDs delivered to the breasts of Irish women attending the symptomatic breast services.

    Symptomatic vaginal discharge is the most frequent symptom in women of reproductive age group. Owing to social stigma majority of affected women hesitate to seek medical consultation. Therefore the actual incidence of vaginal discharge is much more than what is reported. The aim of the study is to determine the microbiological profile of symptomatic vaginal discharge in rural area and its utility in the management of genital tract infection. This was a descriptive type of observational study, conducted in sexually active women of reproductive age group (18-45 years) attending the OPD/IPD of Obstetrics and Gynaecology Department of National Institute of Medical Sciences, Shobhanagar, Jaipur (Rajasthan), over a period of 18 months from June 2012 to December 2013. Hundred sexually active non pregnant women of reproductive age group (18-45 years) were included in the study. After taking consent general physical examination along with pelvic examination was performed. Two high vaginal swabs and blood sample were collected for various tests. Hanging drop preparation was immediately made. This was followed by gram staining and culture. Chlamydia trachomatis IgM antibody was detected by ELISA method. Out of 100 women with symptomatic vaginal discharge, specific diagnosis was obtained in 89% of cases whereas no specific aetiology was found in 11% cases. Mean age was 32.60 years. Fifty-three percent patient had Bacterial vaginosis, candidiasis was found in 14% cases, 16% had Chlamydia trachomatis infection while Trichomonas vaginalis infection was detected in 6% cases. Homogenous discharge was most prevalent (52%), followed by mucopurulant discharge in 23% of women. Patient with symptomatic vaginal discharge need to be actively managed with appropriate antimicrobial agents. Judicious management may be helpful in prevention of HIV, HPV, CIN and post infection sequelae.

    PurposeThe purpose of this study was to determine the feasibility, safety, and early effectiveness of percutaneous image-guided ablation as second-line treatment for symptomatic soft-tissue vascular anomalies (VA).Materials and MethodsAn IRB-approved retrospective review was undertaken of all patients who underwent percutaneous image-guided ablation as second-line therapy for treatment of symptomatic soft-tissue VA during the period from 1/1/2008 to 5/20/2014. US/CT- or MRI-guided and monitored cryoablation or MRI-guided and monitored laser ablation was performed. Clinical follow-up began at one-month post-ablation.ResultsEight patients with nine torso or lower extremity VA were treated with US/CT (N = 4) or MRI-guided (N = 2) cryoablation or MRI-guided laser ablation (N = 5) for moderate to severe pain (N = 7) or diffuse bleeding secondary to hemangioma–thrombocytopenia syndrome (N = 1). The median maximal diameter was 9.0 cm (6.5–11.1 cm) and 2.5 cm (2.3–5.3 cm) for VA undergoing cryoablation and laser ablation, respectively. Seven VA were ablated in one session, one VA initially treated with MRI-guided cryoablation for severe pain was re-treated with MRI-guided laser ablation due to persistent moderate pain, and one VA was treated in a planned two-stage session due to large VA size. At an average follow-up of 19.8 months (range 2–62 months), 7 of 7 patients with painful VA reported symptomatic pain relief. There was no recurrence of bleeding at five-year post-ablation in the patient with hemangioma–thrombocytopenia syndrome. There were two minor complications and no major complications.ConclusionImage-guided percutaneous ablation is a feasible, safe, and effective second-line treatment option for symptomatic VA

There was no recurrence of bleeding at five-year post-ablation in the patient with hemangioma–thrombocytopenia syndrome. There were two minor complications and no major complications.ConclusionImage-guided percutaneous ablation is a feasible, safe, and effective second-line treatment option for symptomatic VA.

    Maternal anaemia prevalence in Bihar, India remains high despite government mandated iron supplementation targeting pregnant women. Inadequate supply has been identified as a potential barrier to iron and folic acid (IFA) receipt. Our study objective was to examine the government health system's IFA supply and distribution system and identify bottlenecks contributing to insufficient IFA supply. Primary data collection was conducted in November 2011 and July 2012 across 8 districts in Bihar, India. A cross-sectional, observational, mixed methods approach was utilized. Auxiliary Nurse Midwives were surveyed on current IFA supply and practices. In-depth interviews (n = 59) were conducted with health workers at state, district, block, health sub-centre, and village levels. Overall, 44% of Auxiliary Nurse Midwives were out of IFA stock. Stock levels and supply chain practices varied greatly across districts. Qualitative data revealed specific bottlenecks impacting IFA forecasting, procurement, storage, disposal, lack of personnel, and few training opportunities for key players in the supply chain. Inadequate IFA supply is a major constraint to the IFA supplementation program, the extent of which varies widely across districts. Improvements at all levels of infrastructure, practices, and effective monitoring will be critical to strengthen the IFA supply chain in Bihar.

    Background Anemia affects over 500 million women, and in pregnancy is associated with impaired maternal and infant outcomes. Intermittent antenatal iron supplementation is an attractive alternative to daily dosing; however, the impact of this strategy on infant outcomes remains unclear. We compared the effect of intermittent antenatal iron supplementation with daily iron supplementation on maternal and infant outcomes in rural Viet Nam. Methods and Findings This cluster randomised trial was conducted in Ha Nam province, Viet Nam. 1,258 pregnant women (<16 wk gestation) in 104 communes were assigned to daily iron–folic acid (IFA), twice weekly IFA, or twice weekly multiple micronutrient (MMN) supplementation. Primary outcome was birth weight. Mean birth weight was 3,148 g (standard deviation 416). There was no difference in the birth weights of infants of women receiving twice weekly IFA compared to daily IFA (mean difference [MD] 28 g; 95% CI −22 to 78), or twice weekly MMN compared to daily IFA (MD −36.8 g; 95% CI −82 to 8.2). At 32 wk gestation, maternal ferritin was lower in women receiving twice weekly IFA compared to daily IFA (geometric mean ratio 0.73; 95% CI 0.67 to 0.80), and in women receiving twice weekly MMN compared to daily IFA (geometric mean ratio 0.62; 95% CI 0.57 to 0.68), but there was no difference in hemoglobin levels. Infants of mothers who received twice weekly IFA had higher cognitive scores at 6 mo of age compared to those who received daily IFA (MD 1.89; 95% CI 0.23 to 3.56). Conclusions Twice weekly antenatal IFA or MMN did not produce a clinically important difference in birth weight, when compared to daily IFA supplementation. The significant improvement in infant cognitive outcomes at 6 mo of age following twice weekly antenatal IFA requires further exploration, and provides additional support for the use of intermittent, rather than daily, antenatal IFA in populations with low rates of iron deficiency.

    Differences in muscle activity patterns between patients with symptomatic and asymptomatic full-thickness rotator cuff tears have not yet been fully clarified. The purpose of this study was to investigate the muscle activity pattern by use of positron emission tomography (PET) in patients with symptomatic and asymptomatic rotator cuff tears. Ten shoulders of 9 patients with full-thickness rotator cuff tears were divided into 2 groups by a numerical pain rating scale (0-10), symptomatic (≥2) and asymptomatic (0 or 1), with 5 shoulders each. Scaption exercise of bilateral arms (200 repetitions in 10 minutes) with a weight of 0.25 kg each was performed before and after injection of fluorodeoxyglucose. After PET examination, the standardized uptake value of each muscle was calculated to quantify its activity and compared between the two groups. The activity of the anterior and middle deltoid was significantly decreased in the symptomatic group compared with the asymptomatic group (anterior deltoid, P = .02; middle deltoid, P = .03). In contrast, the activity of the superior trapezius was significantly increased in the symptomatic group compared with the asymptomatic group (P = .02). In patients with a symptomatic tear, the deltoid activity was decreased and the trapezius activity was increased. It is likely that they might have moved the painful glenohumeral joint less and instead moved the painless scapulothoracic joint more during the prescribed exercise. We conclude that patients with painful rotator cuff tears use the parascapular muscles more than those without pain do during arm elevation.

    Background Pancreatico-jejunostomy strictures (PJS) after pancreatiocoduodenectomy (PD) are poorly understood. Methods Patients treated for PJS were identified from all PDs (n =357) performed for all indications in our practice (2002 to 2009). Technical aspects of the original operation, as well as the presentation, management and outcomes of the resultant stricture were assessed. Results Seven patients developed a symptomatic PJS for an incidence of 2%. ‘Soft’ glands and small ducts (≤3 mm) were each present in 3/7 of the original anastomoses. Pancreatic fistula occurred in 6/7. The latency period to stricture presentation averaged 41 months. Diagnosis of PJS was confirmed by secretin magnetic resonance cholangio-pancreatography (MRCP). Therapeutic endoscopic retrograde cholangiopancreatography (ERCP) was attempted – each unsuccessfully – in four patients. All patients required operative correction of their PJS by takedown/revision of the original pancreatico-jejunal anastomoses (PJA) (n =4) ± a modified Puestow (n =2). One patient's PJS was completely inaccessible due to dense adhesions. Another patient's stricture recurred and was successfully revised with a stricturoplasty. At a mean follow-up of 25 months, all are alive, but only 4/7 are pain free. Conclusion A symptomatic PJS appears to be independent of original pathological, glandular or technical features but pancreatic fistulae may contribute. Secretin MRCP is diagnostically useful, whereas ERCP has been proven to be therapeutically ineffective. Durable resolution of symptoms after surgical revision is unpredictable. PMID:20815857

    Full Text Available Abstract Background Geminiviruses are a large and important family of plant viruses that infect a wide range of crops throughout the world. The Begomovirus genus contains species that are transmitted by whiteflies and are distributed worldwide causing disease on an array of horticultural crops. Symptom remission, in which newly developed leaves of systemically infected plants exhibit a reduction in symptom severity (recovery, has been observed on pepper (Capsicum annuum plants infected with Pepper golden mosaic virus (PepGMV. Previous studies have shown that transcriptional and post-transcriptional gene silencing mechanisms are involved in the reduction of viral nucleic acid concentration in recovered tissue. In this study, we employed deep transcriptome sequencing methods to assess transcriptional variation in healthy (mock, symptomatic, and recovered pepper leaves following PepGMV infection. Results Differential expression analyses of the pepper leaf transcriptome from symptomatic and recovered stages revealed a total of 309 differentially expressed genes between healthy (mock and symptomatic or recovered tissues. Computational prediction of differential expression was validated using quantitative reverse-transcription PCR confirming the robustness of our bioinformatic methods. Within the set of differentially expressed genes associated with the recovery process were genes involved in defense responses including pathogenesis-related proteins, reactive oxygen species, systemic acquired resistance, jasmonic acid biosynthesis, and ethylene signaling. No major differences were found when compared the differentially expressed genes in symptomatic and recovered tissues.

    2011-08-01

    Intracranial arterial stenosis (IAS) is the cause of about 10% of all ischemic strokes in the United States, but may account for about 40% of strokes in some populations. After a stroke or transient ischemic attack due to IAS, patients face a 12% annual risk of recurrent stroke on medical therapy, with most strokes occurring in the first year. Warfarin is no better than aspirin in preventing recurrent strokes but poses a higher risk of serious bleeding and death. Groups with the highest risk of recurrent stroke are those with high-grade (≥ 70%) stenosis, those with recent symptom onset, those with symptoms precipitated by hemodynamic maneuvers, and women. Endovascular treatment of IAS is a rapidly evolving therapeutic option. Antiplatelet agents are currently recommended as the primary treatment for symptomatic IAS, with endovascular therapy reserved for appropriate high-risk cases refractory to medical therapy.

    Headache, a nearly universal experience, remains costly, disabling, and often suboptimally managed. The most common presentations in the United States are migraine, tension-type headache (TTH) and "sinus" headache, but their extensive symptomatic overlap suggests that these conditions can be approached as variations in the same underlying pathology and managed accordingly. We use case studies of patients with varying prior diagnoses (none, migraine, TTH, and sinus headache), as well as a 4-question diagnostic screening tool, to illustrate how pharmacists can use this conceptual framework to simplify identification, management, and referral of patients with primary headache conditions of uncertain etiology. © The Author(s) 2014.

    Background Symptomatic hypocalcemia after thyroidectomy is a barrier to same day surgery, and the cause of ER visits. A standard protocol of calcium and vitamin D supplementation, dependent on intact parathyroid hormone (iPTH) levels, can address this issue. How effective is it? When does it fail? Methods We performed a retrospective review of the prospective Thyroid Database from January 2006 to December 2010. 620 patients underwent completion (CT) or total thyroidectomy (TT), and followed our post-operative protocol of calcium carbonate administration for iPTH levels ≥10pg/ml and calcium carbonate and 0.25μg calcitriol BID for iPTH hypocalcemia. The symptomatic (SX) and asymptomatic (ASX) groups were similar with regard to gender, cancer diagnosis, and pre-operative calcium and iPTH. The symptomatic group was significantly younger (39.6 ± 2.8 vs. 49 ± 0.6 years, p=0.01), with lower post-operative iPTH levels. 33% (n=8) of SX patients had an iPTH ≤5 pg/ml vs. only 6% (n=37) of ASX patients. While the majority of patients with a PTH hypocalcemia after thyroidectomy. An iPTH ≤ 5pg/ml may warrant higher initial doses of calcitriol in order to prevent symptoms. PMID:24144426

    Helicobacter pylori is a highly genetically diverse bacterial species, which can persist in the gastric environment for decades. Recent studies have shown that single infections predominate in developed countries, whereas mixed infections are more prevalent in developing countries. Mixed infections of this bacterium may be important for adaptation to the hostile gastric environment and may facilitate dyspeptic symptoms. To calculate the prevalence of mixed infections in symptomatic and asymptomatic subjects, 2010 H. pylori isolates collected from 83 symptomatic and 91 asymptomatic subjects from Dhaka, Bangladesh, were analyzed by (i) random amplified polymorphic DNA fingerprinting (RAPD) and (ii) multiplex PCR amplification for cagA and vacA virulence gene alleles. The overall prevalence of mixed H. pylori infection was 60.15% (77/128), indicating substantial co-colonization in this population. We additionally found that symptomatic subjects (53%) had a significantly higher rate of mixed infection than asymptomatic individuals (36.3%) (p = .016) and that the prevalence of the cagA and vacA and vacA m1/s1 and vacA m2/s1 alleles were higher in subjects with mixed infection. Our findings suggest that an increased diversity of the H. pylori strains in the gastric environment may contribute to the development of disease symptoms. © 2015 John Wiley & Sons Ltd.

    Respiratory sinus arrhythmia (RSA) reactivity, an index of cardiac vagal tone, has been linked to self-regulation and the severity and course of depression (Rottenberg, 2007). Although initial data supports the proposition that RSA withdrawal during a sad film is a specific predictor of depression course (Fraguas, 2007; Rottenberg, 2005), the robustness and specificity of this finding are unclear. To provide a stronger test, RSA reactivity to three emotion films (happy, sad, fear) and to a more robust stressor, a speech task, were examined in currently depressed individuals (n=37), who were assessed for their degree of symptomatic improvement over 30weeks. Robust RSA reactivity to the sad film uniquely predicted overall symptom improvement over 30weeks. RSA reactivity to both sad and stressful stimuli predicted the speed and maintenance of symptomatic improvement. The current analyses provide the most robust support to date that RSA withdrawal to sad stimuli (but not stressful) has specificity in predicting the overall symptomatic improvement. In contrast, RSA reactivity to negative stimuli (both sad and stressful) predicted the trajectory of depression course. Patients' engagement with sad stimuli may be an important sign to attend to in therapeutic settings. Copyright © 2015 Elsevier B.V. All rights reserved.

    Quality of life (QoL) is becoming a major issue in the evaluation of any therapeutic intervention. To assess the QoL in patients with uncomplicated symptomatic diverticular disease (DD) and to elucidate the influence of two different treatments either on symptoms or QoL. 58 outpatients affected by uncomplicated symptomatic DD, admitted in our Gastroenterological Unit from October 2003 to March 2004, were enrolled. Patients were randomly assigned to two different treatments consisting of rifaximin or mesalazine for 10 days every month for a period of 6 months. QoL was evaluated by means of an SF-36 questionnaire and clinical evaluation was registered by means of a global symptomatic score (GSS) at baseline and after 6 months. At baseline, lower values in all SF-36 domains were confirmed in patients with DD. Both rifaximin and mesalazine groups showed a significant reduction of their mean GSS (p < 0.01 and p < 0.001, respectively) and improvement of SF-36 mean scores after therapy, even though treatment with mesalazine showed better results. DD has a negative impact on QoL. Cyclic treatment with poorly absorbable antibiotics or anti-inflammatory drugs relieves symptoms and improves QoL. 2007 S. Karger AG, Basel

    To find vertebral metastases with high risk of symptomatic malignant spinal cord compression (MSCC), features of vertebral metastases caused motor deficits of the lower extremities were examined. From 2004 through 2006, 78 patients with metastases of the thoracic and/or the cervical spine were treated with radiation therapy (RT). Of these, 86 irradiated lesions in 73 patients were evaluable by magnetic resonance imaging and/or computed tomography at the initiation of RT and were reviewed retrospectively in this study. Twenty-eight patients (38%) had motor deficits at the initiation of RT. Assessed factors were age, sex, primary disease (lung, breast, digestive system and other cancer), lamina involvement, main level of tumor location and vertebral-body involvement. Incidence of motor deficits at the initiation of RT was 55% for lesions with lamina involvement and 5% for lesions without lamina involvement (P 0.9999, P=0.7798, P=0.1702 and P=0.366, respectively). Vertebral metastases with lamina involvement tended to cause symptomatic MSCC. Latent development of MSCC occurred more frequently in the MTS compared with other levels of the thoracic and the cervical spine. (author)

    External beam radiotherapy (EBRT) is the treatment of choice for irresectable meningioma. Due to the strong expression of somatostatin receptors, peptide receptor radionuclide therapy (PRRT) has been used in advanced cases. We assessed the feasibility and tolerability of a combination of both treatment modalities in advanced symptomatic meningioma. 10 patients with irresectable meningioma were treated with PRRT ( 177 Lu-DOTA0,Tyr3 octreotate or - DOTA0,Tyr3 octreotide) followed by external beam radiotherapy (EBRT). EBRT performed after PRRT was continued over 5–6 weeks in IMRT technique (median dose: 53.0 Gy). All patients were assessed morphologically and by positron emission tomography (PET) before therapy and were restaged after 3–6 months. Side effects were evaluated according to CTCAE 4.0. Median tumor dose achieved by PRRT was 7.2 Gy. During PRRT and EBRT, no side effects > CTCAE grade 2 were noted. All patients reported stabilization or improvement of tumor-associated symptoms, no morphologic tumor progression was observed in MR-imaging (median follow-up: 13.4 months). The median pre-therapeutic SUV max in the meningiomas was 14.2 (range: 4.3–68.7). All patients with a second PET after combined PRRT + EBRT showed an increase in SUV max (median: 37%; range: 15%–46%) to a median value of 23.7 (range: 8.0–119.0; 7 patients) while PET-estimated volume generally decreased to 81 ± 21% of the initial volume. The combination of PRRT and EBRT is feasible and well tolerated. This approach represents an attractive strategy for the treatment of recurring or progressive symptomatic meningioma, which should be further evaluated

    Hypoglycemia is common in type 1 diabetes mellitus (T1DM). We aimed to update the incidence of severe and symptomatic hypoglycemia and investigate several correlated factors. In this multicenter, observational retrospective study, the data of 206 T1DM patients from a sample of 2,229 consecutive patients seen at 18 diabetes clinics were analyzed. Sociodemographic and clinical characteristics, severe hypoglycemia in the past 12 months, and symptomatic hypoglycemia in the past 4 weeks were recorded with a self-report questionnaire and a clinical form during a routine visit. Poisson multivariate models were applied. A minority of patients accounted for the majority of both severe and symptomatic episodes. The incidence rate (IR) of severe hypoglycemia was 0.49 (0.40-0.60) events/person-years. The incidence rate ratio (IRR) was higher in patients with previous severe hypoglycemia (3.71; 2.28-6.04), neuropathy (4.16; 2.14-8.05), long duration (>20 years, 2.96; 1.60-5.45), and on polypharmacy (1.24; 1.13-1.36), but it was lower when a complication was present. The IR of symptomatic hypoglycemia was 53.3 events/person-years, with an IRR significantly higher among women or patients with better education, or shorter duration or on pumps. The IRR was lower in patients with higher BMI or neuropathy or aged more than 50 years. Fewer than 20 % of T1DM patients are free from hypoglycemia, with one in six having experienced at least one severe episode in the last year. The distribution is uneven, with a tendency of episodes to cluster in some patients. Severe and symptomatic episodes have different correlates and reflect different conditions.

    Because of the large amount of information to process and the limited time of a clinical consult, choosing between carotid endarterectomy (CEA) and carotid angioplasty with stenting (CAS) can be confusing for patients with severe symptomatic internal carotid stenosis (ICA). We aim to develop a visual aid tool to help clinicians and patients in the decision-making process of selecting between CEA and CAS. Based on pooled analysis from randomized controlled trials including patients with symptomatic and severe ICA (SSICA), we generated visual plots comparing CEA with CAS for 3 prespecified postprocedural time points: (1) any stroke or death at 4 months, and (2) any stroke or death in the first 30 days and ipsilateral stroke thereafter at 5 years and (3) at 10 years. A total of 4574 participants (2393 assigned to CAS, and 2361 to CEA) were included in the analyses. For every 100 patients with SSICA, 6 would develop any stroke or death in the CEA group compared with 9 undergoing CAS at 4 months (hazard ratio [HR] 1.53; 95%CI 1.20-1.95). At 5 years, 7 patients in the CEA group would develop any periprocedural stroke or death and ipsilateral stroke thereafter versus 12 undergoing CAS (HR 1.72; 95%CI 1.24-2.39), compared with 10 patients in the CEA and 13 in the CAS groups at 10 years (HR 1.17; 95%CI 0.82-1.66). Visual aids presented in this study could potentially help patients with severe symptomatic internal carotid stenosis to better weigh the risks and benefits of CEA versus CAS as a function of time, allowing for the prioritization of personal preferences, and should be prospectively assessed.

    Full Text Available Evidence for minimally symptomatic Ebola virus (EBOV infection is limited. During the 2013-16 outbreak in West Africa, it was not considered epidemiologically relevant to published models or projections of intervention effects. In order to improve our understanding of the transmission dynamics of EBOV in humans, we investigated the occurrence of minimally symptomatic EBOV infection in quarantined contacts of reported Ebola virus disease cases in a recognized 'hotspot.'We conducted a cross-sectional serosurvey in Sukudu, Kono District, Sierra Leone, from October 2015 to January 2016. A blood sample was collected from 187 study participants, 132 negative controls (individuals with a low likelihood of previous exposure to Ebola virus, and 30 positive controls (Ebola virus disease survivors. IgG responses to Ebola glycoprotein and nucleoprotein were measured using Alpha Diagnostic International ELISA kits with plasma diluted at 1:200. Optical density was read at 450 nm (subtracting OD at 630nm to normalize well background on a ChroMate 4300 microplate reader. A cutoff of 4.7 U/mL for the anti-GP ELISA yielded 96.7% sensitivity and 97.7% specificity in distinguishing positive and negative controls. We identified 14 seropositive individuals not known to have had Ebola virus disease. Two of the 14 seropositive individuals reported only fever during quarantine while the remaining 12 denied any signs or symptoms during quarantine.By using ELISA to measure Zaire Ebola virus antibody concentrations, we identified a significant number of individuals with previously undetected EBOV infection in a 'hotspot' village in Sierra Leone, approximately one year after the village outbreak. The findings provide further evidence that Ebola, like many other viral infections, presents with a spectrum of clinical manifestations, including minimally symptomatic infection. These data also suggest that a significant portion of Ebola transmission events may have gone

    Full Text Available Background Carotid endarterectomy (CEA is currently the preferred treatment for severe carotid kinking and stenosis. Kinking is generally believed to be a relative contraindication for endovascular stent placement. This article aims to study the necessity, feasibility and security of carotid angioplasty and stenting (CAS for symptomatic carotid kinking combined with stenosis, and summarize clinical experience of this disease according to therapeutic results. Methods Twenty-two cases with symptomatic carotid kinking and high-grade stenosis demonstrated by digital subtraction angiography (DSA were performed CAS. Their clinical manifestations, imaging features, procedure safety and follow-up data were collected and retrospectively analyzed. All patients understood CEA and voluntarily received CAS. Results Twenty-two cases with carotid kinking and stenosis were all successfully performed CAS (the success rate was 100% without stent-related disability or mortality. Twenty-four self-expandable stents were implanted. The mean degree of stenosis was reduced from 85.63%before stenting to 11.25% after stenting and the angles of kinking were improved from 120° (Metz' category. During the period of hospitalization, no transient ischemic attack (TIA or cerebral infarction occurred, and the clinical symptoms and signs of ischemia, such as dizziness and headache, were improved or disappeared. Besides, no permenant complications or deaths happened. All cases were followed up from 6 to 72 months, among whom 1 patient experienced contralateral carotid TIA, and 2 patients experienced ipsilateral carotid TIA (one indicated aspirin resistance in platelet aggregation test and the other showed restenosis in DSA.

    The dorsal patellar defect is a relatively rare entity that involves the superolateral quadrant of the patella. It is usually considered to represent a delayed ossification process, although its exact origin remains unclear. Because of its usually innocuous nature and clinical course, invasive interventions are generally deemed unnecessary, although curretage has been successfully performed on symptomatic cases. This case report presents a rather unusual case of symptomatic bilateral dorsal patellar defects with cartilage involvement and widespread surrounding bone marrow edema as demonstrated by magnetic resonance imaging (MRI). Both cartilage involvement and bone marrow edema should be considered part of the spectrum of associated MRI findings that can be encountered in this entity. Furthermore, the presented case shows that symptomatic dorsal patellar defects can be treated conservatively with success and that (decrease of) pain symptoms are likely related to (decrease of) bone marrow edema.

    Full Text Available Abstract Introduction Pulmonary siderosis secondary to the inhalation of iron compounds is a rare condition which, despite striking radiological and histopathological features, has not traditionally been associated with symptoms or functional impairment. Although not the first of its kind, we present an unusual case of pulmonary siderosis with symptomatic respiratory disease, most likely secondary to associated fibrosis. Case presentation A 66-year-old Caucasian man was referred to the outpatient clinic with a 2-year history of exertional breathlessness. He had worked as an engineer for 20 years where he did a significant amount of welding but always wore a face shield. Clinical, radiological and histological features were consistent with a diagnosis of pulmonary siderosis, with associated fibrosis, most likely related to his occupational welding history. Conclusion Our report illustrates that symptomatic respiratory disease due to mild peribronchiolar fibrosis can occur with pulmonary siderosis despite wearing a mask. Furthermore, it reinforces the need for all clinicians to compile a detailed occupational history in individuals presenting with breathlessness.

    Full Text Available Intravenous bisphosphonates are widely used in the management of solid tumors, metastatic bone disease, metabolic bone diseases and hypercalcemia of malignancies. Recently, yearly intravenous injections of zoledronic acid, one of the potent nitrogen-containing bisphosphonates, have also been approved for the prevention and treatment of osteoporosis. Although infrequently observed, asymptomatic hypocalcemia mainly due to intravenous bisphosphonates has been documented. Here we report a female patient who exhibited profound symptomatic hypocalcemia after receiving intravenous zoledronic acid as treatment of postmenopausal osteoporosis. The patient was not assessed for calcium status prior to the intravenous bisphosphonate therapy, and she was later found to have severe vitamin D deficiency. To our knowledge, this is the first patient with symptomatic hypocalcemia to be reported after zoledronic acid was approved for the management of osteoporosis. We highlight the importance of evaluating calcium and vitamin D levels before initiating intravenous bisphosphonate treatment, particularly in the presence of widespread vitamin D deficiency and the likelihood of future increases in the prescription of intravenous bisphosphonates.

    Full Text Available External focus of attention (EFA and internal focus of attention (IFA represent commonly used strategies to instruct subjects during exercise. Several studies showed EFA to be more effective than IFA to improve motor performance and learning. To date the role of these strategies on motor performance during finger movement was less studied. The objective of the study was to investigate motor performance, patient’s preference induced by IFA and EFA, and the focus during control condition. Ten healthy right-handed participants performed a finger movement task in control, EFA, and IFA conditions (counterbalanced. Errors, patient’s preference, and type of attentional focus spontaneously adopted during the control condition were recorded. EFA determined less error (p<0.01 compared to control and IFA. Participants preferred EFA against IFA and control condition. In the control group 10% of subjects adopted a purely EFA, 70% of subjects adopted a purely IFA, and 20% of subjects adopted a mixture of the two foci. Our results confirm that EFA is more effective than IFA and control in finger movement task. Due its clinical relevance, the interaction between attention and finger movement should be further investigated.

  10. Advantages and limits of hemorrhoidal dearterialization in the treatment of symptomatic hemorrhoids.

    Giamundo, Paolo

    2016-01-27

    In the last two decades, hemorrhoidal dearterialization has become universally accepted as a treatment option for symptomatic hemorrhoids. The rationale for this procedure is based on the assumption that arterial blood overflow is mainly responsible for dilatation of the hemorrhoidal plexus due to the absence of capillary interposition between the arterial and venous systems within the anal canal. Dearterialization, with either suture ligation (Doppler-guided hemorrhoid artery ligation/transanal hemorrhoidal dearterialization) or laser (hemorrhoidal laser procedure), may be successfully performed alone or with mucopexy. Although the added value of Doppler-guidance in association with dearterialization has recently been challenged, this imaging method still plays an important role in localizing hemorrhoidal arteries and, therefore, minimizing the effect of anatomic variation among patients. However, it is important to employ the correct Doppler transducer. Some Doppler transducers may not easily detect superficial arteries due to inadequate frequency settings. All techniques of dearterialization have the advantage of preserving the anatomy and physiology of the anal canal, when compared to other surgical treatments for hemorrhoids. This advantage cannot be underestimated as impaired anal function, including fecal incontinence and other defecation disorders, may occur following surgical treatment for hemorrhoids. Furthermore, this potentially devastating problem can occur in patients of all ages, including younger patients.

    Objective: To describe the experience with liver irradiation in advanced cases of myelofibrosis with myeloid metaplasia (MMM). Methods: Over a 20-yr period, 14 patients with MMM were treated with a total of 25 courses of liver, abdominal, or abdominal and pelvic irradiation for symptomatic hepatomegaly with (5 patients) or without (9 patients) ascites. All 14 patients had advanced disease and 11 (79%) had previous splenectomy. The median radiation therapy (RT) dose per course was 150 cGy (range 50-1000) administered at a median of six fractions. Four patients received two to six courses. Results. Twelve of the 14 patients (86%) had a transient (median 3 months) subjective response from RT. However, in only 35% of these was there a transient (median 3 months) decrease in palpable liver size. Four of the five patients with ascites experienced a short-term response from RT. Eight of the 13 patients suitable for evaluation (62%) had treatment-associated cytopenia, often in the form of anemia and/or thrombocytopenia. At last follow-up, 10 patients (71%) had died after a median of 7 months (range 0.1-23) and 4 were alive at 3, 20, 33, and 57 months after RT. Conclusions: Low-dose abdominal RT for symptomatic hepatomegaly or ascites associated with advanced-stage MMM is myelosuppressive and provides only temporary and mainly subjective and short-lived relief.

    The immunoregulatory molecules programmed death 1 (PD-1) and cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) are associated with the dysfunction of antiviral effector T-cells, which leads to T-cell exhaustion and persistent viral infection in patients with chronic hepatitis C and chronic hepatitis B. Little is known about the role of PD-1 and CTLA-4 in patients with symptomatic acute hepatitis A (AHA). Peripheral blood mononuclear cells were isolated from seven patients with AHA and from six patients with nonviral acute toxic hepatitis (ATH) during the symptomatic and convalescent phases of the respective diseases; five healthy subjects acted as controls. The expression of PD-1 and CTLA-4 on T-cells was measured by flow cytometry. PD-1 and CTLA-4 expression during the symptomatic phase was significantly higher in the T-cells of AHA patients than in those of ATH patients or healthy controls (PD-1 18.3% vs 3.7% vs 1.6%, respectively, p<0.05; CTLA-4 23.5% vs 6.1% vs 5.9%, respectively, p<0.05). The levels of both molecules decreased dramatically during the convalescent phase of AHA, whereas a similar pattern was not seen in ATH. Our findings are consistent with a viral-protective effect of PD-1 and CTLA-4 as inhibitory molecules that suppress cytotoxic T-cells and thereby prevent the destruction of virus-infected hepatocytes in AHA.

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

    Lumbar spondylolysis, a stress fracture of the pars interarticularis, is prevalent in adolescent athletes. Recent advances in diagnostic tools and techniques enable early diagnosis before these fractures progress to complete fractures through the pars. However, because patients often consult family physicians for primary care of low back pain and these physicians may not have access to diagnostic modalities such as magnetic resonance imaging (MRI) and computed tomography, stress fractures can be missed. This study surveyed the prevalence of symptomatic spondylolysis in pediatric patients who consulted an orthopedic clinic for primary care and investigated whether such acute stress fractures may be overlooked without MRI. The prospective study investigated 264 patients who were younger than 19 years and had low back pain. Of the 153 patients (58.0%) with low back pain persisting for longer than 2 weeks, 136 who agreed to undergo MRI were included in the study. This group included 11 elementary school students, 71 junior high school students, and 54 high school students. The overall prevalence of lumbar spondylolysis was 39.7% (54 of 136) and was 9.3% in elementary school students (5 of 11, 45.5%), 59.3% in junior high school students (32 of 71, 45.1%), and 31.5% in high school students (17 of 54, 31.5%). All 54 patients with spondylolysis had a history of athletic activity. Primary care physicians should recognize that approximately 40% of pediatric patients presenting with low back pain persisting for longer than 2 weeks may have spondylolysis and should consider MRI in those with a history of athletic activity. Because the spine is immature in this age group, almost half of affected elementary school and junior high school students may have lumbar spondylolysis. [Orthopedics. 2016; 39(3):e434-e437.].

    Purpose To compare long-term outcome in a population-based group of children with cryptogenic vs symptomatic focal epilepsy diagnosed from 1980–2004 and to define the course of epilepsy in the cryptogenic group. Methods We identified all children residing in Olmsted County, MN, 1 month through 17 years with newly diagnosed, non-idiopathic focal epilepsy from 1980–2004. Children with idiopathic partial epilepsy syndromes were excluded. Medical records were reviewed to determine etiology, results of imaging and EEG studies, treatments used, and long-term outcome. Children were defined as having symptomatic epilepsy if they had a known genetic or structural/metabolic etiology, and as cryptogenic if they did not. Key Findings Of 359 children with newly-diagnosed epilepsy, 215 (60%) had non-idiopathic focal epilepsy. Of these, 206 (96%) were followed for more than 12 months. Ninety five children (46%) were classified as symptomatic. Median follow-up from diagnosis was similar in both groups, being 157 months (25%ile, 75%ile 89, 233) in the cryptogenic group vs 134 months (25%ile, 75%ile 78, 220) in the symptomatic group (p=0.26). Of 111 cryptogenic cases, 66% had normal cognition. Long-term outcome was significantly better in those with cryptogenic vs symptomatic etiology (intractable epilepsy at last follow-up, 7% vs 40%, p<0.001; seizure-freedom at last follow-up, 81% vs 55%, p<0.001). Of those who achieved seizure-freedom at final follow-up, 68% of the cryptogenic group versus only 46% of the symptomatic group were off antiepileptic medications (p=0.01). One third of the cryptogenic group had a remarkably benign disorder, with no seizures seen after initiation of medication, or in those who were untreated, after the second afebrile seizure. A further 5% had seizures within the first year but remained seizure-free thereafter. With the exception of perinatal complications, which predicted against seizure remission, no other factors were found to significantly

    Ipilimumab (a monoclonal antibody against CTLA-4) and nivolumab (a humanized antibody against PD-1) target these immune checkpoint pathways and are used for treatment of melanoma and an increasing number of other cancers. However, they may cause immune-related adverse effects (IRAEs). Although many endocrinopathies are known to be IRAEs, primary hypoparathyroidism with severe hypocalcemia has never been reported. This is the first case of hypoparathyroidism as an IRAE presenting to an Emergency Department with acute hypocalcemia. A 73-year-old man with metastatic melanoma presented to the Emergency Department for the chief complaints of imbalance, general muscle weakness, abdominal pain and tingling in extremities. He had wide spread metastasis, and begun immunotherapy with concurrent ipilimumab and nivolumab 1.5months ago. At presentation, he had ataxia, paresthesia in the hands and feet, and abdominal cramping. Magnetic resonance imaging of the brain was unremarkable. He was found to be hypocalcemic with undetectable plasma parathyroid hormone. He was admitted for treatment of symptomatic hypocalcemia and was diagnosed with primary hypoparathyroidism. Shortly afterwards, he had thyrotoxicosis manifesting as tachycardia and anxiety, followed by development of primary hypothyroidism. At 4months after the Emergency Department visit, his parathyroid function and thyroid function had not recovered, and required continued thyroid hormone replacement and calcium and vitamin D treatment for hypocalcemia. Primary hypoparathyroidism caused by ipilimumab and nivolumab may acute manifest with severe symptomatic hypocalcemia. Emergency care providers should be aware of hypoparathyroidism as a new IRAE in this new era of immuno-oncology. Copyright © 2017 Elsevier Inc. All rights reserved.

    In light of recent controversy about the safety and efficacy of intracranial stenting, we sought to evaluate our experience with primary balloon angioplasty for symptomatic, high-grade intracranial stenosis. All intracranial angioplasty cases performed at Vanderbilt University Medical Center from 2006 to 2011 were retrospectively reviewed for degree of stenosis pre- and post-procedure. Immediate peri-procedural complications were evaluated as well as one-month and long-term outcomes. A total of 26 patients were included in the study with a mean age of 63.0 years and a mean follow-up of 350.2 days. The average pre-procedure stenosis was 71.2%. The immediate, average post-procedure stenosis was 46.6%, and the average post-procedure stenosis at last angiographic follow-up was 44.5%. Retreatment was required in only 3.8% of patients. The primary end-point of major stroke or death at 30 days was observed in 11.5%, and the overall intra-procedural complication rate was 7.7%. The incidence of stroke or death at last follow-up was 15.4%, which is comparable to the one-year stroke or death rate in the medical arm of the SAMPRISS trial. In this retrospective series, primary balloon angioplasty was found to be effective as a treatment option for symptomatic intracranial stenosis with the risk of stroke or death at 30 days higher than the medical arm of SAMPRIS but lower than the stenting arm. The one-year risk of stroke was comparable to that reported for the one-year outcomes in the SAMPRISS medical arm.

    Even if usually asymptomatic, uterine myomas have been associated with a number of clinical issues such as abnormal uterine bleeding (AUB), heavy menstrual bleeding (HMB), infertility, recurrent pregnancy loss, especially when these masses are submucous. Golden standard treatment for symptomatic submucous fibroids has long been considered their laparotomic removal or a total hysterectomy. The development of endoscopy has made these fibroids accessible and removable from the inner surface of uterus. Hysteroscopy arose as a diagnostic technique, but then it also became an alternative surgical technique for many diseases, offering therapeutic and irreplaceable possibilities of treatment, avoiding major surgery on the one hand, and allowing the correction of pathologies specifically related to female fertility, on the other hand. Excision by slicing has been described as traditional resectoscopic submucosal myomectomy, but today there are new procedures among which the operator can choose, that allow overcoming the initial limitations of the traditional resectoscopic myomectomy in clinical practice.

    The development of minimally invasive techniques allowed access to the necrotic cavity through transperitoneal, retroperitoneal, transmural and transpapillary routes. The choice of access to walled-off pancreatic necrosis (WOPN) should depend not only on the spread of necrosis, but also on the experience of the clinical center. Herein we describe treatment of a patient with multilocular symptomatic walled-off pancreatic necrosis using minimally invasive techniques. The single transmural access (single transluminal gateway technique - SGT) to the necrotic collection of the patient was ineffective. The second gastrocystostomy was performed using the same minimally invasive technique as an extra way of access to the necrosis (multiple transluminal gateway technique - MTGT). In the described case the performance of the new technique consisting in endoscopic multiplexing transmural access (MTGT) was effective enough and led to complete recovery of the patient.

It is usually considered to represent a delayed ossification process, although its exact origin remains unclear. Because of its usually innocuous nature and clinical course, invasive interventions are generally deemed unnecessary, although curretage has been successfully performed on symptomatic cases. This case report presents a rather unusual case of symptomatic bilateral dorsal patellar defects with cartilage involvement and widespread surrounding bone marrow edema as demonstrated by magnetic resonance imaging (MRI). Both cartilage involvement and bone marrow edema should be considered part of the spectrum of associated MRI findings that can be encountered in this entity.

    There is growing evidence for the efficacy and effectiveness of psychotherapy in patients with personality disorder (PD), but very little is known about the factors underlying these effects. Two-polarities models of personality development provide an empirically supported approach to studying therapeutic change. Briefly, these models argue that personality pathology is characterized by an imbalance between development of the capacity for self-definition and for relatedness, with an exaggerated emphasis on issues regarding self-definition and relatedness being expressed in high levels of self-critical perfectionism (SCP) and dependency, respectively. This study used data from a study of 111 patients with PD who received long-term hospitalization-based psychodynamic treatment to investigate whether (a) treatment was related to changes in SCP, dependency, and symptomatic distress; (b) these changes could be explained by pretreatment levels of SCP, dependency, and/or symptomatic distress; and (c) changes in these personality dimensions over time were associated with symptomatic improvement. SCP, dependency, and symptomatic distress were assessed at admission (baseline), at 12 and 24 weeks into treatment, and at discharge. Parallel process multilevel growth modeling showed that (a) treatment was associated with a significant decrease in levels of SCP, dependency, and symptomatic distress, whereas (b) pretreatment levels of each of these three factors did not predict the decreases observed, and (c) changes in SCP, but not dependency, were associated with the rate of decrease in symptomatic distress over time. Implications of these findings for our understanding of therapeutic change in the treatment of PD are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    This study investigated isometric and isokinetic hip strength in individuals with and without symptomatic femoroacetabular impingement (FAI). The specific aims were to: (i) determine whether differences exist in isometric and isokinetic hip strength measures between groups; (ii) compare hip strength agonist/antagonist ratios between groups; and (iii) examine relationships between hip strength and self-reported measures of either hip pain or function in those with FAI. Cross-sectional. Fifteen individuals (11 males; 25±5 years) with symptomatic FAI (clinical examination and imaging (alpha angle >55° (cam FAI), and lateral centre edge angle >39° and/or positive crossover sign (combined FAI))) and 14 age- and sex-matched disease-free controls (no morphological FAI on magnetic resonance imaging) underwent strength testing. Maximal voluntary isometric contraction strength of hip muscle groups and isokinetic hip internal (IR) and external rotation (ER) strength (20°/s) were measured. Groups were compared with independent t-tests and Mann-Whitney U tests. Participants with FAI had 20% lower isometric abduction strength than controls (p=0.04). There were no significant differences in isometric strength for other muscle groups or peak isokinetic ER or IR strength. The ratio of isometric, but not isokinetic, ER/IR strength was significantly higher in the FAI group (p=0.01). There were no differences in ratios for other muscle groups. Angle of peak IR torque was the only feature correlated with symptoms. Individuals with symptomatic FAI demonstrate isometric hip abductor muscle weakness and strength imbalance in the hip rotators. Strength measurement, including agonist/antagonist ratios, may be relevant for clinical management of FAI. Copyright © 2015 Sports Medicine Australia. Published by Elsevier Ltd. All rights reserved.

    The objective of this study was to make an assessment of the utility of fine needle aspiration cytology (FNAC), in a "one-stop" symptomatic breast triple assessment clinic. Controversy surrounds the optimal tissue biopsy methodology in the diagnosis of symptomatic breast cancer and the identification of benign disease. FNAC in the context of a Rapid Assessment Breast Clinic (RABC) allows the same day diagnosis and early treatment of breast cancer, with the immediate reassurance and discharge of those with benign disease. We analyzed prospective data accrued at a RABC, over a 4-year period from 2004 to 2007. All patients were triple assessed, with FNACs performed on site by two consultant cytopathologists. Investigations were reported immediately, and clinical data were captured via a database using compulsory data field entry. There were 4487 attendances at our RABC, with 1572 FNACs were performed. The positive predictive value of FNAC with a C5 cancer diagnosis was 100%, 95.6% for a C4 report, with a complete sensitivity of 94%. The full specificity of correctly identified benign lesions was 77.4%, with a false negative rate of 3.85%. This enabled 66% of patients attending the RABC to receive a same day diagnosis of benign disease and discharge. FNAC is highly accurate in the diagnosis of symptomatic breast cancer in an RABC. FNAC allows accurate diagnosis of benign disease and immediate discharge of the majority of patients. In this era, when a large majority of patients have benign disease, we believe that FNAC provides an equivalent, if not better, method of evaluation of patients in a triple assessment RABC.

    Purpose To determine the short-term and long-term adherence rates with continuous positive airway pressure (CPAP) therapy in sleep apnea patients with benign prostatic hyperplasia (BPH) compared to matched controls. Methods A case-control retrospective analysis was performed in a veterans affairs hospital. All symptomatic patients with BPH (n = 107) ever started on CPAP therapy between 2006 and 2012 were compared with controls matched for severity of sleep apnea (AHI). Adherence measures were obtained at the third and twelfth month visits. The cases included symptomatic BPH patients on active medical therapy. Diuretic use among cases and controls, and severity of nocturia among the cases were also analyzed. Results The mean AHI among cases and controls was 35.6 ± 27.3 and 35.5 ± 31 (p = 0.96). The population was male and predominantly Caucasian. There was no statistically significant difference in percent days CPAP device use ≥4 h. between symptomatic BPH patients and controls at 3-month (51.6 ± 38 vs. 47.2 ± 36; p = 0.43) and 1-year (64 ± 40.5 vs. 64.7 ± 31.3; p = 0.90) visits. The use of diuretics in the cases and controls, and the severity of nocturia in the cases did not influence adherence with CPAP therapy. Conclusions BPH or diuretic use did not affect adherence with CPAP therapy in obstructive sleep apnea. Severity of nocturia did not have any influence on adherence among the cases. BPH, regardless of the severity of nocturia, and diuretic use does not influence CPAP adherence in patients with OSA.

    Purpose: To investigate predictive factors in the development of symptomatic radiation injury after treatment with linear accelerator–based stereotactic radiosurgery for intracerebral arteriovenous malformations and relate the findings to the conclusions drawn by Quantitative Analysis of Normal Tissue Effects in the Clinic (QUANTEC). Methods and Materials: Archived plans for 73 patients who were treated at the British Columbia Cancer Agency were studied. Actuarial estimates of freedom from radiation injury were calculated using the Kaplan-Meier method. Univariate and multivariate Cox proportional hazards models were used for analysis of incidence of radiation injury. Log–rank test was used to search for dosimetric parameters associated with freedom from radiation injury. Results: Symptomatic radiation injury was exhibited by 14 of 73 patients (19.2%). Actuarial rate of symptomatic radiation injury was 23.0% at 4 years. Most patients (78.5%) had mild to moderate deficits according to Common Terminology Criteria for Adverse Events, version 4.0. On univariate analysis, lesion volume and diameter, dose to isocenter, and a V x for doses ≥8 Gy showed statistical significance. Only lesion diameter showed statistical significance (p 5 cm 3 and diameters >30 mm were significantly associated with the risk of radiation injury (p 12 also showed strong association with the incidence of radiation injury. Actuarial incidence of radiation injury was 16.8% if V 12 was 3 and 53.2% if >28 cm 3 (log–rank test, p = 0.001). Conclusions: This study confirms that the risk of developing symptomatic radiation injury after radiosurgery is related to lesion diameter and volume and irradiated volume. Results suggest a higher tolerance than proposed by QUANTEC. The widely differing findings reported in the literature, however, raise considerable uncertainties.

    PurposeTo describe a modified endovascular technique for complete revascularization of visceral and renal arteries in symptomatic pararenal aortic aneurysm (PRAA).TechniqueArterial access was surgically established in both common femoral arteries (CFAs) and the left subclavian artery (LSA). Revascularization of the left renal artery, the celiac trunk, and the superior mesenteric artery was performed through one single sheath via the LSA. Suitable covered stents were put in the aortic branches but not deployed. The right renal artery was accessed over the left CFA. Due to the longitudinal extension of the presented aneurysm two stent-grafts were introduced via the right CFA. After deploying the aortic stent-grafts, all covered stents in the side branches were deployed consecutively with a minimum overlap of 5 mm over the cranial and caudal stent-graft edges. Simultaneous ballooning was performed to fully expand all stent-grafts and warranty patency. Conclusion: This is the first report in the literature of chimney grafting in PRAA for complete revascularization of visceral and renal branches by using more than two covered stents introduced from one side through one single sheath. However this technique is modified, it should be used only in bailout situations when branched stent-grafts are not available and/or surgery is not suitable.

    Intracranial developmental venous anomalies (DVAs) are considered benign vascular dispositions; they are asymptomatic in the vast majority of cases. They represent extreme variations of the venous drainage and may rarely be responsible for focal venous ischemia leading to neurological dysfunction. The aim of the study is to analyze a group of patients with symptomatic DVAs with capillary stain at angiography. We retrospectively reviewed the clinical and radiological features of patients in which a DVA was considered the cause of a neurological event. In all the patients, the DVA was suspected by angio-CT or MRI and conventional angiography was performed to detail the angioarchitecture of the DVA. A total of 7 patients and 11 DVAs were identified; three patients had multiple DVAs. Three DVAs were frontal, two were parietal, two were thalamic, one was in the midbrain, and three were cerebellar. Patients presented with progressive neurological deficits, seizures, or cerebral hemorrhage. All these DVAs were associated with a peculiar capillary stain at angiography. Although being normal anatomical variations, DVAs may create, because of hemodynamic unbalance, venous ischemia that induces angiogenic phenomena. MRI shows the suffering of the brain and angiography witnesses this angiogenesis under the form of capillary stain. Conventional angiography can thus provide useful information to recognize ''atypical'' symptomatic DVAs. (orig.)

    Mediastinal aortic vascular anomalies are relatively common causes of extrinsic central airway narrowing in infants with respiratory symptoms. Surgical correction of mediastinal aortic vascular anomalies alone might not adequately treat airway symptoms if extrinsic narrowing is accompanied by intrinsic tracheomalacia (TM), a condition that escapes detection on routine end-inspiratory imaging. Paired inspiratory-expiratory multidetector CT (MDCT) has the potential to facilitate early diagnosis and timely management of TM in symptomatic infants with mediastinal aortic vascular anomalies. To assess the technical feasibility of paired inspiratory-expiratory MDCT for evaluating TM among symptomatic infants with mediastinal aortic vascular anomalies. The study group consisted of five consecutive symptomatic infants (four male, one female; mean age 4.1 months, age range 2 weeks to 6 months) with mediastinal aortic vascular anomalies who were referred for paired inspiratory-expiratory MDCT during a 22-month period. CT angiography was concurrently performed during the end-inspiration phase of the study. Two pediatric radiologists in consensus reviewed all CT images in a randomized and blinded fashion. The end-inspiration and end-expiration CT images were reviewed for the presence and severity of tracheal narrowing. TM was defined as ≥50% reduction in tracheal cross-sectional luminal area between end-inspiration and end-expiration. The presence of TM was compared to the bronchoscopy results when available (n = 4). Paired inspiratory-expiratory MDCT was technically successful in all five patients. Mediastinal aortic vascular anomalies included a right aortic arch with an aberrant left subclavian artery (n = 2), innominate artery compression (n = 2), and a left aortic arch with an aberrant right subclavian artery (n 1). Three (60%) of the five patients demonstrated focal TM at the level of mediastinal aortic vascular anomalies. The CT results were concordant with the results

    Background and purpose: Inflammation is a risk factor the vulnerable atheromatous plaque. This can be detected in vivo on high-resolution magnetic resonance (MR) imaging using a contrast agent, Sinerem TM , an ultra-small super-paramagnetic iron oxide (USPIO). The aim of this study was to explore whether there is a difference in the degree of MR defined inflammation using USPIO particles, between symptomatic and asymptomatic carotid plaques. We report further on its T 1 effect of enhancing the fibrous cap, which may allow dual contrast resolution of carotid atheroma. Methods: Twenty patients with carotid stenosis (10 symptomatic and 10 asymptomatic) underwent multi-sequence MR imaging before and 36 h post-USPIO infusion. Images were manually segmented into quadrants and signal change in each quadrant was calculated following USPIO administration. Mean signal change across all quadrants were compared between the two groups. Results: Symptomatic patients had significantly more quadrants with a signal drop than asymptomatic individuals (75% vs. 32%, p < 0.01). Asymptomatic plaques had more quadrants with signal enhancement than symptomatic ones (68% vs. 25%, p < 0.05); their mean signal change was also higher (46% vs. 15%, p < 0.01) and this appeared to correlate with a thicker fibrous cap on histology. Conclusions: Symptomatic patients had more quadrants with signal drop suggesting larger inflammatory infiltrates. Asymptomatic individuals showed significantly more enhancement possibly suggesting greater stability as a result of thicker fibrous caps. However, some asymptomatic plaques also had focal areas of signal drop, suggesting an occult macrophage burden. If validated by larger studies, USPIO may be a useful dual contrast agent able to improve risk stratification of patients with carotid stenosis and inform selection for intervention.

    Full Text Available The skin has an important role in the transmission of visceral leishmaniasis (VL as the infection pathway in dogs. To better characterize the inflammatory response of intact skin in VL, sixty infected dogs (30 symptomatic and 30 asymptomatic and six non-infected controls were studied. Diagnosis of visceral leishmaniasis was confirmed by RIFI and ELISA; direct visualization of the parasite in bone marrow aspirate; imprints of popliteal lymph nodes, spleen, liver and skin; culture in NNN-phase liquid Schneider's medium; and PCR (performed only in the ear skin. Amastigote forms of the parasite in intact skin were found only in symptomatic dogs. Inflammatory infiltrates were observed in all groups, varying from intense and/or moderate in symptomatic to discrete and/or negligible in asymptomatic and control animals. Parasite load was associated with the intensity of the inflammatory response and with clinical manifestations in canine visceral leishmaniasis. AgNOr as active transcription markers were expressed in inflammatory cells and within apoptotic bodies in all groups, including controls, with no statistical difference. Therefore, cell activation and transcription do occur in both symptomatic and asymptomatic canine visceral leishmaniasis and may result in more necrosis and inflammation or in apoptosis and less symptoms, depending on the parasite load.

  13. Pre-symptomatic activation of antioxidant responses and alterations in glucose and pyruvate metabolism in Niemann-Pick Type C1-deficient murine brain.

    Full Text Available Niemann-Pick Type C (NPC disease is an autosomal recessive neurodegenerative disorder caused in most cases by mutations in the NPC1 gene. NPC1-deficiency is characterized by late endosomal accumulation of cholesterol, impaired cholesterol homeostasis, and a broad range of other cellular abnormalities. Although neuronal abnormalities and glial activation are observed in nearly all areas of the brain, the most severe consequence of NPC1-deficiency is a near complete loss of Purkinje neurons in the cerebellum. The link between cholesterol trafficking and NPC pathogenesis is not yet clear; however, increased oxidative stress in symptomatic NPC disease, increases in mitochondrial cholesterol, and alterations in autophagy/mitophagy suggest that mitochondria play a role in NPC disease pathology. Alterations in mitochondrial function affect energy and neurotransmitter metabolism, and are particularly harmful to the central nervous system. To investigate early metabolic alterations that could affect NPC disease progression, we performed metabolomics analyses of different brain regions from age-matched wildtype and Npc1 (-/- mice at pre-symptomatic, early symptomatic and late stage disease by (1H-NMR spectroscopy. Metabolic profiling revealed markedly increased lactate and decreased acetate/acetyl-CoA levels in Npc1 (-/- cerebellum and cerebral cortex at all ages. Protein and gene expression analyses indicated a pre-symptomatic deficiency in the oxidative decarboxylation of pyruvate to acetyl-CoA, and an upregulation of glycolytic gene expression at the early symptomatic stage. We also observed a pre-symptomatic increase in several indicators of oxidative stress and antioxidant response systems in Npc1 (-/- cerebellum. Our findings suggest that energy metabolism and oxidative stress may present additional therapeutic targets in NPC disease, especially if intervention can be started at an early stage of the disease.

    A rotavirus VP4 gene P[6] allele has been documented in a number of countries to be characteristically associated with an endemic predominantly asymptomatic infection in neonates in maternity hospital nurseries. The mechanisms underlying the endemicity and asymptomatic nature of such neonatal infections remain unknown. Rotavirus strains sharing this same P genotype, however, have more recently been recovered from an increasing number of symptomatic diarrheal episodes in infants and young children in various parts of the world. Previously, we have shown that an asymptomatic P[6] rotavirus neonatal infection is not associated with a unique VP7 (G) serotype but may occur in conjunction with various G types. Although amino acid sequence comparisons of the VP4 gene between selected 'asymptomatic' and 'symptomatic' P[6] rotavirus strains have been reported and yielded information concerning their VP4 genotypes, serotypic comparisons of the outer capsid spike protein VP4 of such viruses have not been studied systematically by two-way cross-neutralizations. We determined the VP4 neutralization specificities of four asymptomatic and four symptomatic P[6] strains: two each of asymptomatic and symptomatic strains by two-way tests, and two each of additional asymptomatic and symptomatic strains by one-way tests. Both asymptomatic and symptomatic P[6] strains were shown to bear similar, if not identical, VP4 neutralization specificities. Thus, P[6] rotavirus strains causing asymptomatic or symptomatic infections did not appear to belong to unique P (VP4) serotypes. In addition, a close VP4 serotypic relationship between human P[6] rotavirus strains and the porcine P[6] rotavirus Gottfried strain was confirmed

    Meckel's diverticulum (MD) is the most prevalent congenital anomaly of the gastrointestinal tract and often presents a diagnostic challenge. Patients with trisomy 18 frequently have MD, but the poor prognosis and lack of consensus regarding management for neonates has meant that precise information on the clinical manifestations in infants and children with MD is lacking. We describe the cases of three children with trisomy 18 who developed symptomatic MD. Intussusception was diagnosed in Patient 1, intestinal volvulus in Patient 2, and gastrointestinal bleeding in Patient 3. All three patients underwent surgical treatment and only the Patient 1 died due to pulmonary hypertensive crisis. The other two patients experienced no further episodes of abdominal symptoms. In patients with trisomy 18, although consideration of postoperative complications and prognosis after surgical treatment is necessary, symptomatic MD should carry a high index of suspicion in patients presenting with acute abdomen. © 2015 Wiley Periodicals, Inc.

  16. Factors Associated with Tuberculosis and Rifampicin-Resistant Tuberculosis amongst Symptomatic Patients in India: A Retrospective Analysis.

    Full Text Available Tuberculosis remains a major public health challenge for India. Various studies have documented different levels of TB and multi-drug resistant (MDR TB among diverse groups of the population. In view of renewed targets set under the End TB strategy by 2035, there is an urgent need for TB diagnosis to be strengthened. Drawing on data from a recent, multisite study, we address key questions for TB diagnosis amongst symptomatics presenting for care: are there subgroups of patients that are more likely than others, to be positive for TB? In turn, amongst these positive cases, are there factors-apart from treatment history-that may be predictive for multi-drug resistance?We used data from a multi-centric prospective demonstration study, conducted from March 2012 to December 2013 in 18 sub-district level TB programme units (TUs in India and covering a population of 8.8 million. In place of standard diagnostic tests, upfront Xpert MTB/RIF testing was offered to all presumptive TB symptomatics. Here, using data from this study, we used logistic regression to identify association between risk factors and TB and Rifampicin-Resistant TB among symptomatics enrolled in the study.We find that male gender; history of TB treatment; and adult age compared with either children or the elderly are risk factors associated with high TB detection amongst symptomatics, across the TUs. While treatment history is found be a significant risk factor for rifampicin-resistant TB, elderly (65+ yrs people have significantly lower risk than other age groups. However, pediatric TB cases have no less risk of rifampicin resistance as compared with adults (OR 1.23 (95% C.I. 0.85-1.76. Similarly, risk of rifampicin resistance among both the genders was the same. These patterns applied across the study sites involved. Notably in Mumbai, amongst those patients with microbiological confirmation of TB, female patients showed a higher risk of having MDR-TB than male patients.Our results

    Epilepsy can be one of symptoms of the damage to CNS in children with neurodevelopmental deficits, it is more difficult however to diagnose seizures if they are the first symptom of severe brain damage. This retrospective research was conducted to study causes of symptomatic epilepsy in children aged 3-18 year hospitalized between 2006 and 2007 year in the Department of Pediatric Neurology. 156 children with symptomatic epilepsy occurred after 2 years of life were included. The diagnosis of symptomatic epilepsy was established including clinical picture, neuro-radiological tests and EEG. The information from parents was helpful to analyze the type of seizures. The clinical state of children was analyzed, especially psychomotor development, focal deficits, as well as results of CT and/or MRI, in some children psychological testing was performed, molecular or serological. 156 children with epilepsy were hospitalized, within encephalopathy was diagnosed in 61 children. In 42 children static encephalopathy was associated with birth trauma, in 7 progressive encephalopathy was diagnosed, in 1 child CO intoxication caused encephalopathy, and in 11 cases the cause was not identified. Malformations of nervous system were associated with epilepsy in 37 children, geneticaly determined syndromes in 6, and the head trauma in other 6 children. Disorders of vascular origin caused epilepsy in 16 children, and neuroinfections in 9 children. In 2 children epilepsy was associated with ADEM, and in 11 children nonspecific de/dysmyelination was detected. The brain tumor was detected in 6 children with symptomatic epilepsy. The most common disorder leading to epilepsy in children aged 3-18 years was encephalopathy, within hypoxic-ischemic encephalopathy. The other in sequence were malformations of nervous system and vascular diseases.

    Full Text Available Schistosomiasis constitutes a major public health problem, with an estimated 200 million people infected worldwide. Many areas of Brazil show low endemicity of schistosomiasis, and the current standard parasitological techniques are not sufficiently sensitive to detect the low-level helminth infections common in areas of low endemicity (ALEs. This study compared the Kato-Katz (KK; Hoffman, Pons, and Janer (HH; enzyme-linked immunosorbent assay- (ELISA- IgG and ELISA-IgM; indirect immunofluorescence technique (IFT-IgM; and qPCR techniques for schistosomiasis detection in serum and fecal samples, using the circumoval precipitin test (COPT as reference. An epidemiological survey was conducted in a randomized sample of residents from five neighborhoods of Barra Mansa, RJ, with 610 fecal and 612 serum samples. ELISA-IgM (21.4% showed the highest positivity and HH and KK techniques were the least sensitive (0.8%. All techniques except qPCR-serum showed high accuracy (82–95.5%, differed significantly from COPT in positivity P<0.05, and showed poor agreement with COPT. Medium agreement was seen with ELISA-IgG (Kappa = 0.377 and IFA (Kappa = 0.347. Parasitological techniques showed much lower positivity rates than those by other techniques. We suggest the possibility of using a combination of laboratory tools for the diagnosis of schistosomiasis in ALEs.

    Fusiform dilation of the internal carotid artery (FDICA) is an infrequent vascular complication following resection of suprasellar lesions in the pediatric population, and its course appears to be benign without apparent clinical symptoms. However, data correlating symptomatic FDICA with bypass surgery are scarce. The authors here report 2 symptomatic cases that were treated using internal maxillary artery bypass more than 5 years after total removal of a craniopharyngioma at an outside institution. Both cases of FDICA were resected to relieve the mass effect and to expose the craniopharyngioma. The postoperative course was uneventful, and radiological imaging revealed graft conduit patency. To the authors' knowledge, this is the first reported use of extracranial to intracranial bypass to treat FDICA following removal of a suprasellar lesion. Their findings suggest that bypass surgery is a useful therapeutic approach for symptomatic cases of FDICA and total removal of recurrent craniopharyngioma. Moreover, the indications for surgical intervention and treatment modalities are discussed in the context of previous relevant cases.

    We tested the effects of a saw palmetto herbal blend in men with symptomatic benign prostatic hyperplasia (BPH) via a randomized, placebo controlled trial. We randomized 44 men 45 to 80 years old with symptomatic BPH into a trial of a saw palmetto herbal blend versus placebo. End points included routine clinical measures (symptom score, uroflowmetry and post-void residual urine volume), blood chemistry studies (prostate specific antigen, sex hormones and multiphasic analysis), prostate volumetrics by magnetic resonance imaging, and prostate biopsy for zonal tissue morphometry and semiquantitative histology studies. Saw palmetto herbal blend and placebo groups had improved clinical parameters with a slight advantage in the saw palmetto group (not statistically significant). Neither prostate specific antigen nor prostate volume changed from baseline. Prostate epithelial contraction was noted, especially in the transition zone, where percent epithelium decreased from 17.8% at baseline to 10.7% after 6 months of saw palmetto herbal blend (p saw palmetto herbal blend (p saw palmetto herbal blend. When the study was no longer blinded, 41 men elected to continue therapy in an open label extension. Saw palmetto herbal blend appears to be a safe, highly desirable option for men with moderately symptomatic BPH. The secondary outcome measures of clinical effect in our study were only slightly better for saw palmetto herbal blend than placebo (not statistically significant). However, saw palmetto herbal blend therapy was associated with epithelial contraction, especially in the transition zone (p <0.01), indicating a possible mechanism of action underlying the clinical significance detected in other studies.

    There is a growing interest in the objective assessment of health related outcomes using technology providing quality measurements to be applied not only in daily clinical practice, but also in scientific research. Differences in the understandings of the condition and the terminology used between people with Parkinson's (PwPs), clinicians and technical developers may influence the progress of a participatory design process. This paper reports on a participatory design process to achieve a consensus among PwPs, clinicians and technologists over the selection of a set of symptomatic domains to be continuously assessed, in order to provide results relevant to both PwPs and clinicians. The methods used were a Web based user survey, end-user focus groups, ranking by combined methods, a Delphi process performed among clinicians and scientists, and prioritization of the results in a concertation workshop for PwPs, clinicians and technologists. The following symptomatic domains were commonly agreed by PwPs and clinicians to be of central importance in a system of continuous assessment: hypokinesia/bradykinesia, tremor, sway, gait, sleep and cognition. This list satisfied both the needs of the PwPs and the concerns of the clinicians regarding the means of advancing new strategies in assessment and interventions in PD. A participatory design strategy allowed the definition of a consensual list of symptomatic domains. Both the strategy and the achieved results may be of relevance for similar interdisciplinary approaches in the field of PD using a participatory design involving patients, clinicians and technologists.

    Purpose: To compare perioperative and follow-up outcomes of symptomatic versus asymptomatic patients following endovascular repair of anastomotic pseudoaneurysms (APAs) of the abdominal aorta and iliac arteries. Methods: We retrospectively evaluated 17 patients (two women), with a mean age of 66.2 years (range 30–83 years). Endovascular treatment was performed in ten symptomatic, and seven asymptomatic patients electively. Data included technical success, perioperative (within 30 days) mortality and morbidity, as well as stent graft-related complications, reinterventions, and survival in follow-up. Results: Bifurcated (n = 13), aortomonoiliac (n = 3) endoprosthesis and one aortic cuff were implanted with a primary technical success rate of 100%. The overall in-hospital mortality and morbidity rate was 11.8% and 35.3%. The mean survival was 36.5 (range 0–111) months. There was a clear trend toward a lower overall survival within hospital and at one and three years for symptomatic patients compared to asymptomatic patients. (47.7 (CI: 0–138.8) versus 52.6 (CI: 28.5–76.8) months (p = 0.274)). During follow-up, late stent graft related complications were observed in six patients (35.3%) necessitating eight endovascular reinterventions. Additional three patients with primary fistulas between the APA and the intestine were treated by late surgical revision. Conclusion: Endovascular therapy of APAs represents a considerable alternative to open surgical repair. Short proximal anchoring zones still pose a risk for endoleaks and unintentional overstenting of side branches with commercially available devices, but this might be overcome by use of fenestrated and branched stent grafts in elective cases.

    The aim of this study was to evaluate whether mobile kidney pain provocation ultrasonography together with intravenous pyelography in supine and standing positions and a full medical history can confirm the diagnosis of the clinical condition of symptomatic mobile kidney and aid the selection of patients for surgical treatment. In a consecutive study, 43 patients with the clinical picture of symptomatic mobile kidney, a positive mobile kidney pain provocation ultrasonography and a renal descent of at least 2 lumbar vertebral heights on intravenous pyelography in the standing position, were operated on with nephropexy. Patients' pain relief after nephropexy was evaluated by clinical follow-up, a questionnaire and visual analogue scale (VAS) scoring. Reduction of pain after nephropexy was associated with a significant decrease in VAS scoring from a median of 8 (range 4-10) preoperatively to a median of 0 (range 0-7) postoperatively (p mobile kidney pain provocation ultrasonography and intravenous pyelography in supine and standing positions can verify the diagnosis of symptomatic mobile kidney and aid the selection of patients who will benefit from nephropexy.

    Full Text Available Abstract Background A recent study of adults aged ≥50 years reporting knee pain found an excess of radiographic knee osteoarthritis (knee ROA in symptomatic males compared to females. This was independent of age, BMI and other clinical signs and symptoms. Since this finding contradicts many previous studies, our objective was to explore four possible explanations for this gender difference: X-ray views, selection, occupation and non-articular conditions. Methods A community-based prospective study. 819 adults aged ≥50 years reporting knee pain in the previous 12 months were recruited by postal questionnaires to a research clinic involving plain radiography (weight-bearing posteroanterior semiflexed, supine skyline and lateral views, clinical interview and physical examination. Any knee ROA, ROA severity, tibiofemoral joint osteoarthritis (TJOA and patellofemoral joint osteoarthritis (PJOA were defined using all three radiographic views. Occupational class was derived from current or last job title. Proportions of each gender with symptomatic knee ROA were expressed as percentages, stratified by age; differences between genders were expressed as percentage differences with 95% confidence intervals. Results 745 symptomatic participants were eligible and had complete X-ray data. Males had a higher occurrence (77% of any knee ROA than females (61%. In 50–64 year olds, the excess in men was mild knee OA (particularly PJOA; in ≥65 year olds, the excess was both mild and moderate/severe knee OA (particularly combined TJOA/PJOA. This male excess persisted when using the posteroanterior view only (64% vs. 52%. The lowest level of participation in the clinic was symptomatic females aged 65+. Within each occupational class there were more males with symptomatic knee ROA than females. In those aged 50–64 years, non-articular conditions were equally common in both genders although, in those aged 65+, they occurred more frequently in symptomatic

    To report on long-term clinical course in patients with symptomatic occipital lobe epilepsy secondary to neonatal hypoglycemia. Six patients with neonatal hypoglycemia and symptomatic occipital lobe epilepsy were studied in our hospital through reviewing their medical records retrospectively. The median onset age of epilepsy was 2 years 8 months and median follow-up period was 12 years and 4 months. Initial seizure types were generalized convulsions in 4 patients, hemiconvulsion in 1, and infantile spasms in 1. Ictal manifestations of main seizures were identical to occipital lobe seizures, such as eye deviation, eye blinking, ictal vomiting, and visual hallucination. Seizure frequency was maximum during infancy and early childhood and decreased thereafter with no seizure in 2 patients, a few seizures a year in 3, and once a month in 1. All patients had status epilepticus in the early course of epilepsy. EEGs showed parieto-occipital spikes in all patients. MRI revealed cortical atrophy and T2 prolongation parieto-occipitally in 4 patients, hippocampal atrophy in 1, and unremarkable in 1. This study indicates that epilepsy secondary to neonatal hypoglycemia is intractable during infancy and early childhood with frequent status epilepticus but tends to decrease in older age.

    To assess the bleeding risk profile using the HAS-BLED score in patients with symptomatic peripheral artery disease (PAD). A post hoc analysis was performed using data from a series of 115 consecutive patients (mean age 72.4±11.4 years; 68 men) with symptomatic PAD undergoing endovascular revascularization. The endpoint of the study was to assess bleeding risk using the 9-point HAS-BLED score, which was previously validated in cohorts of patients with and without atrial fibrillation. For the purpose of this study, the low (0-1), intermediate (2), and high-risk (≥3) scores were stratified as low/intermediate risk (HAS-BLED risk (HAS-BLED ≥3). The mean HAS-BLED score was 2.76±1.16; 64 (56%) patients had a HAS-BLED score ≥3.0. Patients with PAD Rutherford category 5/6 ischemia had an even higher mean HAS-BLED score (3.20±1.12). Logistic regression analysis revealed aortoiliac or femoropopliteal segment involvement, chronic kidney disease, as well as Rutherford category 5/6, to be independent risk factors associated with a HAS-BLED score ≥3. Patients with PAD, especially those presenting with Rutherford category 5/6 ischemic symptoms, have high HAS-BLED scores, suggesting increased risk for major bleeding. Prospective clinical validation of the HAS-BLED score in patients with PAD may help with the risk-benefit assessment when prescribing antithrombotic therapy. © The Author(s) 2016.

    Management of congestive heart failure is a serious public health problem. The use of implantable hemodynamic monitors (IHMs) may assist in this management by providing continuous ambulatory filling pressure status for optimal volume management. The Chronicle system includes an implanted monitor, a pressure sensor lead with passive fixation, an external pressure reference (EPR), and data retrieval and viewing components. The tip of the lead is placed near the right ventricular outflow tract to minimize risk of sensor tissue encapsulation. Implant technique and lead placement is similar to that of a permanent pacemaker. After the system had been successfully implanted in 148 patients, the type and frequency of implant-related adverse events were similar to a single-chamber pacemaker implant. R-wave amplitude was 15.2 +/- 6.7 mV and the pressure waveform signal was acceptable in all but two patients in whom presence of artifacts required lead repositioning. Implant procedure time was not influenced by experience, remaining constant throughout the study. Based on this evaluation, permanent placement of an IHM in symptomatic heart failure patients is technically feasible. Further investigation is warranted to evaluate the use of the continuous hemodynamic data in management of heart failure patients.

    Spinal stenosis can be a very disabling condition. Surgical decompression carries a risk of dural tear and neural injury, which is increased in patients with severe stenosis or an atypical anatomy. We present an unusual case of symptomatic stenosis secondary to achondroplasia presenting in a paediatric patient, and highlight a new surgical technique used to minimise the risk of dural and neural injury during decompression.

    Purpose: To determine factors associated with symptomatic cardiac toxicity in patients with esophageal cancer treated with chemoradiotherapy. Material and methods: We retrospectively evaluated 102 patients treated with chemoradiotherapy for locally advanced esophageal cancer. Our primary endpoint was symptomatic cardiac toxicity. Radiation dosimetry, patient demographic factors, and myocardial changes seen on 18 F-FDG PET were correlated with subsequent cardiac toxicity. Cardiac toxicity measured by RTOG and CTCAE v3.0 criteria was identified by chart review. Results: During the follow up period, 12 patients were identified with treatment related cardiac toxicity, 6 of which were symptomatic. The mean heart V20 (79.7% vs. 67.2%, p = 0.05), V30 (75.8% vs. 61.9%, p = 0.04), and V40 (69.2% vs. 53.8%, p = 0.03) were significantly higher in patients with symptomatic cardiac toxicity than those without. We found the threshold for symptomatic cardiac toxicity to be a V20, V30 and V40 above 70%, 65% and 60%, respectively. There was no correlation between change myocardial SUV on PET and cardiac toxicity, however, a greater proportion of women suffered symptomatic cardiac toxicity compared to men (p = 0.005). Conclusions: A correlation did not exist between percent change in myocardial SUV and cardiac toxicity. Patients with symptomatic cardiac toxicity received significantly greater mean V20, 30 and 40 values to the heart compared to asymptomatic patients. These data need validation in a larger independent data set.

    Mammography screening reduces breast cancer mortality by up to 32%. However, some recent studies have questioned the impact of non-palpable breast cancer detection on mortality reduction. The aim of this study was to analyse the clinicopathological and long-term follow-up data of early stage screened and symptomatic breast cancer patients. The institutional prospectively led database was systematically analysed for breast cancer cases diagnosed via the mammography screening program from 2002 to 2009. As a control group, symptomatic early stage breast cancer patients were collected randomly from the same database and matched for age and follow-up period. All medical records were reviewed retrospectively. Data from 298 breast cancer patients were collected from 47,718 mammography screenings. In addition, 331 symptomatic breast cancer patients were randomly selected. The screened group presented a significantly lower median tumour size (P screened group (P screened group did not exhibit better overall (P = 0.717) or disease-free survival (P = 0.081) compared to the symptomatic group. Our results do not suggest that mammography screening does not reduce breast cancer mortality but the mammography screening did not bring any significant improvement in patient overall or disease-free survival for the early stage breast cancer patients compared to the symptomatic group. The drawback of symptomatic early stage tumours compared to non-palpable tumours could be equalized by modern multimodality oncology treatments.

    Full Text Available Abstract Background To evaluate the palliative role of radiotherapy (RT and define the effectiveness of chemotherapy combined with palliative RT (CCRT in patients with a symptomatic pelvic mass of metastatic colorectal cancer. Methods From August 1995 to December 2007, 80 patients with a symptomatic pelvic mass of metastatic colorectal cancer were treated with palliative RT at Samsung Medical Center. Initial presenting symptoms were pain (68 cases, bleeding (18 cases, and obstruction (nine cases. The pelvic mass originated from rectal cancer in 58 patients (73% and from colon cancer in 22 patients (27%. Initially 72 patients (90% were treated with surgery, including 64 complete local excisions; 77% in colon cancer and 81% in rectal cancer. The total RT dose ranged 8-60 Gy (median: 36 Gy with 1.8-8 Gy per fraction. When the α/β for the tumor was assumed to be 10 Gy for the biologically equivalent dose (BED, the median RT dose was 46.8 Gy10 (14.4-78. Twenty one patients (26% were treated with CCRT. Symptom palliation was assessed one month after the completion of RT. Results Symptom palliation was achieved in 80% of the cases. During the median follow-up period of five months (1-44 months, 45% of the cases experienced reappearance of symptoms; the median symptom control duration was five months. Median survival after RT was six months. On univariate analysis, the only significant prognostic factor for symptom control duration was BED ≥40 Gy10 (p Conclusions RT was an effective palliation method in patients with a symptomatic pelvic mass of metastatic colorectal cancer. For improvement of symptom control rate and duration, a BED ≥ 40 Gy10 is recommended when possible. Considering the low morbidity and improved symptom palliation, CCRT might be considered in patients with good performance status.

    Full Text Available BACKGROUND/OBJECTIVES: Chronic heart failure (CHF is one of the most important public health concerns in the industrialized world having increasing incidence and prevalence. Although there are several studies describing the prevalence of heart failure with reduced ejection fraction (HFREF and heart failure with normal ejection fraction (HFNEF in selected populations, there are few data regarding the prevalence and the determinants of symptomatic heart failure in the general population. METHODS: Cross-sectional data of a population-based German sample (1,779 subjects aged 45-83 years were analyzed to determine the prevalence and determinants of chronic SHF and HFNEF defined according to the European Society of Cardiology using symptoms, echocardiography and serum NT-proBNP. Prevalence was age-standardized to the German population as of December 31st, 2005. RESULTS: The overall age-standardized prevalence of symptomatic CHF was 7.7% (95%CI 6.0-9.8 for men and 9.0% (95%CI 7.0-11.5 for women. The prevalence of CHF strongly increased with age from 3.0% among 45-54- year-old subjects to 22.0% among 75-83- year-old subjects. Symptomatic HFREF could be shown in 48% (n = 78, symptomatic HFNEF in 52% (n = 85 of subjects with CHF. The age-standardized prevalence of HFREF was 3.8 % (95%CI 2.4-5.8 for women and 4.6 % (95%CI 3.6-6.3 for men. The age-standardized prevalence of HFNEF for women and men was 5.1 % (95%CI 3.8-7.0 and 3.0 % (95%CI 2.1-4.5, respectively. Persons with CHF were more likely to have hypertension (PR = 3.4; 95%CI 1.6-7.3 or to have had a previous myocardial infarction (PR = 2.5, 95%CI 1.8-3.5. CONCLUSION: The prevalence of symptomatic CHF appears high in this population compared with other studies. While more women were affected by HFNEF than men, more male subjects suffered from HFREF. The high prevalence of symptomatic CHF seems likely to be mainly due to the high prevalence of cardiovascular risk factors in this population.

Symptomatic severe hyponatremia induced by low-dose cyclophosphamide is very uncommon worldwide. We report a case of severe symptomatic hyponatremia that developed in a female breast cancer patient following the first cycle of chemotherapy containing low-dose cyclophosphamide. Her laboratory test showed serum Na of 112 mmol/L. Her hyponatremia was initially treated with sodium bicarbonate. She completely recovered without neurological deficits after slow correction of the serum Na concentration. Although hyponatremia is a rare toxicity it should always be considered during the usage of cyclophosphamide, even if the dosage is low, especially with concurrent use of other medications that impair water excretion, like chlorthalidone. This report describes the first reported case of cyclophosphamide-induced hyponatremia in Qatar.Keywords: AC protocol, adjuvant chemotherapy, breast cancer, cyclophosphamide, hyponatremia, thiazides

    Full Text Available Dengue is a mosquito-borne disease that is common in many tropical and subtropical areas. Dengue infections can occur at any age and time in the lifespan, including during pregnancy. Few large scale studies have been conducted to determine the risk of preterm birth (PTB and low birthweight (LBW for infants born to women who had symptomatic dengue infection during pregnancy.This study is a retrospective cohort study using medical records from 1992-2010 from pregnant women who attended a public regional referral hospital in western French Guiana. Exposed pregnancies were those with laboratory confirmed cases of dengue fever during pregnancy. Each of the 86 exposed infants was matched to the three unexposed births that immediately followed them to form a stratum. Conditional logistic regression was used to analyze these matched strata. Three groups were examined: all infants regardless of gestational age, only infants> = 17 weeks of gestational age and their strata, and only infants> = 22 weeks of age and their strata. Odds ratios were adjusted (aOR for maternal age, maternal ethnicity, maternal gravidity, interpregnancy interval and maternal anemia. There was an increased risk of PTB among women with symptomatic dengue; (aOR all infants: 3.34 (1.13, 9.89, aOR 17 weeks: 1.89 (0.61, 5.87, aOR 22 weeks: 1.41 (0.39, 5.20 but this risk was only statistically significant when all infants were examined (p value = 0.03. Adjusted results for LBW were similar, with an increased risk in the exposed group (aOR All infants: 2.23 (1.01, 4.90, aOR 17 weeks: 1.67 (0.71, 3.93, aOR 22 weeks: 1.43 (0.56, 3.70 which was only statistically significant when all infants were examined (p value = 0.05.Symptomatic dengue infection during pregnancy may increase the risk of PTB and LBW for infants. More research is needed to confirm these results and to examine the role of dengue fever in miscarriage.

    In the UK, despite its low sensitivity, wet mount microscopy is often the only method of detecting Trichomonas vaginalis infection. A study was conducted in symptomatic women to compare the performance of five methods for detecting T. vaginalis: an in-house polymerase chain reaction (PCR); Aptima T. vaginalis kit; OSOM ®Trichomonas Rapid Test; culture and microscopy. Symptomatic women underwent routine testing; microscopy and further swabs were taken for molecular testing, OSOM and culture. A true positive was defined as a sample that was positive for T. vaginalis by two or more different methods. Two hundred and forty-six women were recruited: 24 patients were positive for T. vaginalis by two or more different methods. Of these 24 patients, 21 patients were detected by real-time PCR (sensitivity 88%); 22 patients were detected by the Aptima T. vaginalis kit (sensitivity 92%); 22 patients were detected by OSOM (sensitivity 92%); nine were detected by wet mount microscopy (sensitivity 38%); and 21 were detected by culture (sensitivity 88%). Two patients were positive by just one method and were not considered true positives. All the other detection methods had a sensitivity to detect T. vaginalis that was significantly greater than wet mount microscopy, highlighting the number of cases that are routinely missed even in symptomatic women if microscopy is the only diagnostic method available. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    The usefulness of magnetic resonance (MR) angiography using the three-dimensional time-of-flight method for the characterization of symptomatic middle cerebral artery (MCA) occlusive lesions was evaluated in 10 patients with MCA occlusion and 10 with MCA stenosis. All lesions were symptomatic and documented by conventional angiography. There was no false-negative MR angiogram that failed to demonstrate the MCA occlusive lesion. MR angiography correctly evaluated the location of lesions and the difference between stenosis and occlusion. Stenosis appeared as a focal signal loss (<1.0cm) of the MCA at the site of stenosis, and occlusion as a complete signal loss of the MCA distal to the site of occlusion. However, MR angiography could not distinguish diffuse stenosis and one point stenosis demonstrated by conventional angiography. MR angiography is a useful noninvasive diagnostic method for evaluating occlusive lesions of the MCA in symptomatic patients. (author).

    Full Text Available Abstract Background Symptomatic Acromioclavicular (AC dislocations have historically been surgically treated with Coracoclavicular (CC ligament reconstruction with transfer of the Coracoacromial (CA ligament. Tensioning the CA ligament is the key to success. Methods Seventeen patients with chronic, symptomatic Type III AC joint or acute Type IV and V injuries were treated surgically. The distal clavicle was resected and stabilized with CC ligament reconstruction using the CA ligament. The CA ligament was passed into the medullary canal and tensioned, using a modified 'docking' technique. Average follow-up was 29 months (range 12–57. Results Postoperative ASES and pain significantly improved in all patients (p = 0.001. Radiographically, 16 (94% maintained reduction, and only 1 (6% had a recurrent dislocation when he returned to karate 3 months postoperatively. His ultimate clinical outcome was excellent. Conclusion The docking procedure allows for tensioning of the transferred CA ligament and healing of the ligament in an intramedullary bone tunnel. Excellent clinical results were achieved, decreasing the risk of recurrent distal clavicle instability.

    Background and purpose: Inflammation is a risk factor the vulnerable atheromatous plaque. This can be detected in vivo on high-resolution magnetic resonance (MR) imaging using a contrast agent, Sinerem{sup TM}, an ultra-small super-paramagnetic iron oxide (USPIO). The aim of this study was to explore whether there is a difference in the degree of MR defined inflammation using USPIO particles, between symptomatic and asymptomatic carotid plaques. We report further on its T{sub 1} effect of enhancing the fibrous cap, which may allow dual contrast resolution of carotid atheroma. Methods: Twenty patients with carotid stenosis (10 symptomatic and 10 asymptomatic) underwent multi-sequence MR imaging before and 36 h post-USPIO infusion. Images were manually segmented into quadrants and signal change in each quadrant was calculated following USPIO administration. Mean signal change across all quadrants were compared between the two groups. Results: Symptomatic patients had significantly more quadrants with a signal drop than asymptomatic individuals (75% vs. 32%, p < 0.01). Asymptomatic plaques had more quadrants with signal enhancement than symptomatic ones (68% vs. 25%, p < 0.05); their mean signal change was also higher (46% vs. 15%, p < 0.01) and this appeared to correlate with a thicker fibrous cap on histology. Conclusions: Symptomatic patients had more quadrants with signal drop suggesting larger inflammatory infiltrates. Asymptomatic individuals showed significantly more enhancement possibly suggesting greater stability as a result of thicker fibrous caps. However, some asymptomatic plaques also had focal areas of signal drop, suggesting an occult macrophage burden. If validated by larger studies, USPIO may be a useful dual contrast agent able to improve risk stratification of patients with carotid stenosis and inform selection for intervention.

    To perform a systematic review and meta-analysis on the association between knee extensor strength and the risk of structural, symptomatic, or functional deterioration in individuals with or at risk of knee osteoarthritis (KOA). We systematically identified and methodologically appraised all longitudinal studies (≥1-year followup) reporting an association between knee extensor strength and structural (tibiofemoral, patellofemoral), symptomatic (self-reported, knee replacement), or functional (subjective, objective) decline in individuals with or at risk of radiographic or symptomatic KOA. Results were pooled for each of the above associations using meta-analysis, or if necessary, summarized according to a best-evidence synthesis. Fifteen studies were included, evaluating >8,000 participants (51% female), with a followup time between 1.5 and 8 years. Meta-analysis revealed that lower knee extensor strength was associated with an increased risk of symptomatic (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC] pain: odds ratio [OR] 1.35, 95% confidence interval [95% CI] 1.10-1.67) and functional decline (WOMAC function: OR 1.38, 95% CI 1.00-1.89, and chair-stand task: OR 1.03, 95% CI 1.03-1.04), but not increased risk of radiographic tibiofemoral joint space narrowing (JSN) (OR 1.15, 95% CI 0.84-1.56). No trend in risk was observed for KOA status (present versus absent). Best-evidence synthesis showed inconclusive evidence for lower knee extensor strength being associated with increased risk of patellofemoral deterioration. Meta-analysis showed that lower knee extensor strength is associated with an increased risk of symptomatic and functional deterioration, but not tibiofemoral JSN. The risk of patellofemoral deterioration in the presence of knee extensor strength deficits is inconclusive. © 2016, American College of Rheumatology.

    Cross-reacting antibodies enhanced dengue infection in humans and antibody dependent enhancement (ADE) have been proposed as early mechanisms underlying DHF/DSS. However, the duration of dengue IgG antibodies in the body as well as factors associated with said duration remain unclear. Blood samples from 59 dengue symptomatic persons and 48 asymptomatic individuals were collected. Study participant demographic information (including age in 2009, gender, and place of residence) were also collected. Serum samples were tested for dengue specific IgG by Panbio dengue IgG indirect enzyme-linked immunosorbent assay (ELISA). Chi-square tests and logistic regression analysis of dengue IgG antibodies seroprevalence divided by gender, age groups, and symptomatic or asymptomatic infection were conducted using the Statistical Package for the Social Sciences. Overall, 70 (65.42%) blood samples were seropositive for dengue IgG antibodies with similar seroprevalences found when dividing by gender and different age groups. However, seroprevalence of dengue IgG antibodies in samples from dengue symptomatic persons was significantly higher than that in samples from asymptomatic individuals (96.61% vs 27.08%) according to multivariable logistic regression analysis, the odds ratio (OR) of the factor was 76.731. Dengue IgG antibodies were detectable in samples from most individuals three years after infection. Dengue symptomatic persons had a higher dengue IgG prevalence compared to asymptomatic individuals.

    The aim of this study was to evaluate the use of Doppler ultrasonography (DUS) and semi-rigid ureteroscopy (URS) for managing symptomatic persistent hydronephrosis during pregnancy. The study included 19 pregnant patients with unilateral symptomatic persistent hydronephrosis. All pregnant patients were assessed with conventional ultrasonography (US) followed by DUS for both kidneys. The mean patient age was 26 years (range 19-40), and the gestational period was 24 weeks (range 16-33). There was a significantly higher mean resistive index in the kidneys with ureteral obstruction than in the contralateral normal kidneys. Spinal anesthesia was performed on 18 patients, while general anesthesia was performed on 1 patient. Endoscopically stones were found in 17 patients (89.5%), while no stone was found in 2 patients (10.5%). The stones were fragmented by holmium laser and retracted with forceps. After lithotripsy, a ureteral JJ stent was inserted in 8 of 17 (47%) patients with ureteral stones. Intraoperatively, there were no obstetric complications, while ureteral perforation was seen in one patient. Two patients are still pregnant at the time of this writing, and 17 babies were born normally. Both RI and ΔRI increase in unilateral symptomatic persistent hydronephrosis during pregnancy. Semi-rigid URS can be used successfully for diagnosis and treatment in these patients. Copyright © 2012 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

    The authors evaluated long-term postoperative visual outcomes and recurrence rates following surgery for symptomatic epiretinal membrane (ERM) ± internal limiting membrane (ILM) peeling. This was a retrospective, consecutive case series of 78 patients undergoing vitrectomy for symptomatic ERM between 1/2010 and 4/2012 with follow-up through at least postoperative year 5 (POY5). Outcomes included visual acuity (VA) (Snellen VA converted to logMAR), central retinal thickness (CRT; μm), and ERM recurrence. Subgroup analysis evaluated outcomes related to ILM peeling. Subgroup analysis based on ILM peeling did not find VA (20/50 [0.430 logMAR ± 0.061 logMAR; mean ± SD] vs. 20/60 [0.518 logMAR ± 0.128 logMAR] for ILM vs. non-ILM peeling respectively; P = .513) nor macular thickness (355 μm ± 13 μm vs. 360 μm ± 42 μm; P = .410) to be significantly different at POY5. Recurrence requiring surgery with and without ILM peeling was not statistically significantly different at POY5 (1.6% and 11.8%; P = .118). Vitrectomy for symptomatic ERM led to improved visual and anatomic outcomes with sustained benefit through 5 years. ILM peeling was was associated with reduced ERM recurrence, but this benefit was not statistically significant at POY5. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:296-302.].

    Intracranial developmental venous anomalies (DVAs) are considered benign vascular dispositions; they are asymptomatic in the vast majority of cases. They represent extreme variations of the venous drainage and may rarely be responsible for focal venous ischemia leading to neurological dysfunction. The aim of the study is to analyze a group of patients with symptomatic DVAs with capillary stain at angiography. We retrospectively reviewed the clinical and radiological features of patients in which a DVA was considered the cause of a neurological event. In all the patients, the DVA was suspected by angio-CT or MRI and conventional angiography was performed to detail the angioarchitecture of the DVA. A total of 7 patients and 11 DVAs were identified; three patients had multiple DVAs. Three DVAs were frontal, two were parietal, two were thalamic, one was in the midbrain, and three were cerebellar. Patients presented with progressive neurological deficits, seizures, or cerebral hemorrhage. All these DVAs were associated with a peculiar capillary stain at angiography. Although being normal anatomical variations, DVAs may create, because of hemodynamic unbalance, venous ischemia that induces angiogenic phenomena. MRI shows the suffering of the brain and angiography witnesses this angiogenesis under the form of capillary stain. Conventional angiography can thus provide useful information to recognize ''atypical'' symptomatic DVAs. (orig.)

    Improvements in liver surgery have led to decreased mortality rates. Symptomatic perihepatic collections (SPHCs) requiring percutaneous drainage remain a significant source of morbidity. A single institution's prospectively maintained hepatic resection database was reviewed to identify patients who underwent hepatectomy between January 2004 and February 2012. Data from 2173 hepatectomies performed in 2040 patients were reviewed. Overall, 200 (9%) patients developed an SPHC, the majority non-bilious (75.5%) and infected (54%). Major hepatic resections, larger than median blood loss (≥360 ml), use of surgical drains, and simultaneous performance of a colorectal procedure were associated with an SPHC on multivariate analysis. Non-bilious, non-infected (NBNI) collections were associated with lower white blood cell (WBC) counts, absence of a bilio-enteric anastomosis, use of hepatic arterial infusion pump (HAIP), and presence of metastatic disease, and resolved more frequently with a single interventional radiology (IR) procedure (85 vs. 46.5%, p < 0.001) more quickly (15 vs. 30 days, p = 0.001). SPHCs developed in 9% of patients in a modern series of hepatic resections, and in one third were non-bilious and non-infected. In the era of modern interventional radiology, the need for re-operation for SPHC is exceedingly rare. A significant proportion of minimally symptomatic SPHC patients may not require drainage, and strategies to avoid unnecessary drainage are warranted.

    To analyze symptomatic treatment in patients with multiple sclerosis (MS). Multiple sclerosis is a chronic inflammatory disease of the central nervous system, with accumulating disability symptoms like spasticity, voiding disorders, depression, and pain might occur. The nationwide German MS registry was initiated 2001 under guidance of the German MS society (Deutsche MS Gesellschaft). This study was performed as an interim analysis to lay foundation for future work on this topic. A subcohort of 5113 patients was assessed for this interim analysis. The mean age of the patients was 45.3 years; mean EDSS was 4.2. More than two-third of the enrolled patients were females (70.9%). Most frequent symptoms were fatigue (60%), followed by spasticity (52.5%) and voiding disorders (51.7%). The likelihood of treatment was highest for epileptic disorders (68.8%), spasticity (68.5%), pain (60.7%), and depression (58.9%). Multivariate regression analysis showed that retirement was the strongest factor predictive for antispastic treatment (β=.061, P=.005). Almost all patients in this analysis suffer from symptoms due to advanced MS. Treatment for the various symptoms differed tremendously. The likelihood of treatment correlated with the availability of effective therapeutic agents. Clinicians should put more awareness on MS symptoms. Symptomatic treatment may improve quality of life. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Symptomatic Rathke cleft cysts (RCCs) are rarely detected in neuroradiological screening and are less commonly found in children than in adults. However, when RCCs are observed in children, it is important to carefully distinguish a RCC from a cystic craniopharyngioma (CP) even if surgically treated or conservatively followed up. We conducted a retrospective review of clinical data from 11 patients with symptomatic RCCs whose ages were under 18 years and compared the data with data from 15 age- and sex-matched patients with cystic CP who were treated at our institute. The mean age of the patients with RCCs was 12.2 years (range, 6-18). There were six males and five females. As initial symptoms, nine patients presented with headache, while two each had impaired visual function, diabetes insipidus, and activity loss. The 14 patients with CP suffered from impaired visual function. Magnetic resonance imaging (MRI) mainly showed hyperintensity on T1-weighted images (WIs) and hypointensity on T2-WI in patients with RCC. However, patients with CP had characteristic hyperintensity on T2-WI. The average maximum diameter of the RCCs was 19.0 mm on average (range, 8-33 mm). The RCCs were thus significantly smaller than CPs (34.9 mm; range, 21-54 mm). The RCCs were usually oval or dumbbell-shaped and regular in appearance, while the larger CPs were lobular and irregular. A preoperative endocrinological evaluation revealed insufficiencies in four axes in five patients with RCC. Postoperative endocrinological status improved in three patients, remained unchanged in three, and worsened in one. The gonadotropin axis was damaged in a majority (nine) of the patients with CP preoperatively. Postoperative evaluation revealed deficits in five axes in 14 patients with CP, which is a significantly different trend than observed in patients with RCC. Eight patients underwent surgical procedures (transsphenoidal surgery (TSS) in four, craniotomy in four). Two of these patients

    Developmental symptomatic C1 canal stenosis is very rare. We describe the computed tomography (CT) and magnetic resonance imaging (MRI) appearances in a 8-year-old child who presented with progressive upper and lower limb neurological symptoms and in whom imaging revealed the medial posterior hemiarches of a bifid C1 to be inturned and compressing the cervical cord. This particular configuration of the posterior arch of atlas is frequently associated with other craniocervical bony anomalies and presents with neurological symptoms early in life. Early CT or MRI examination of patients with symptomatic posterior arch of C1 defects is necessary, in order to detect such an appearance, since surgical treatment may prevent neurological deterioration.

    In the last two decades, hemorrhoidal dearterialization has become universally accepted as a treatment option for symptomatic hemorrhoids. The rationale for this procedure is based on the assumption that arterial blood overflow is mainly responsible for dilatation of the hemorrhoidal plexus due to the absence of capillary interposition between the arterial and venous systems within the anal canal. Dearterialization, with either suture ligation (Doppler-guided hemorrhoid artery ligation/transa...

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

    Anterior cruciate ligament (ACL) tears are associated with the development of knee osteoarthritis despite ACL reconstruction surgery. However, little evidence is available to determine which patients will develop symptomatic knee osteoarthritis. To determine if preoperative outcome measures-KOOS (Knee injury and Osteoarthritis Outcome Score) and SF-36 (36-item Short Form Health Survey)-were associated with the development of a symptomatic knee 7 years after ACL reconstruction. A secondary goal was to examine the relationship between imaging evidence of knee osteoarthritis and development of knee pain. Case-control study; Level of evidence, 3. Prospectively collected data from 72 patients were reviewed with 7-year follow-up after unilateral ACL reconstruction. Patients were divided into symptomatic and asymptomatic groups based on the previously defined KOOS pain ≤72. Demographic variables and preoperative KOOS and SF-36 scores were compared between groups. Radiographic and magnetic resonance imaging data were used to evaluate differences in joint space width, Osteoarthritis Research Society International radiographic score, and the Whole-Organ Magnetic Resonance Imaging Score between groups. Univariate and multivariate analyses were performed to identify potential predictors of pain at 7-year follow-up. Wilcoxon sum rank and t tests were used to compare imaging findings between the symptomatic and asymptomatic patients at 7 years. According to KOOS pain, 7 of the 72 patients available at 7-year follow-up formed the symptomatic group. No differences were found between groups in regard to demographic variables or intraoperative findings. In multivariate analysis, lower preoperative scores for KOOS sports/recreation ( P = .005) and SF-36 mental health ( P = .025) were associated with a painful knee at 7 years, with increased odds of 82% and 68% per 10-unit decrease, respectively. The Whole-Organ Magnetic Resonance Imaging Score at 7 years showed evidence of

    Mycoplasma contamination in cell culture is a serious setback for the cell-culturist. The experiments undertaken using contaminated cell cultures are known to yield unreliable or false results due to various morphological, biochemical and genetic effects. Earlier surveys revealed incidences of mycoplasma contamination in cell cultures to range from 15 to 80%. Out of a vast array of methods for detecting mycoplasma in cell culture, the cytological methods directly demonstrate the contaminating organism present in association with the cultured cells. In this investigation, we report the adoption of a cytological immunofluorescence assay (IFA), in an attempt to obtain a semi-automated relative quantification of contamination by employing the user-friendly Photoshop-based image analysis. The study performed on 77 cell cultures randomly collected from various laboratories revealed mycoplasma contamination in 18 cell cultures simultaneously by IFA and Hoechst DNA fluorochrome staining methods. It was observed that the Photoshop-based image analysis on IFA stained slides was very valuable as a sensitive tool in providing quantitative assessment on the extent of contamination both per se and in comparison to cellularity of cell cultures. The technique could be useful in estimating the efficacy of anti-mycoplasma agents during decontaminating measures.

    Purpose: This paper presents a modification of the known method for percutaneous treatment of hydatid cyst, the PAIR technique. It aimed to achieve safe aspiration of large symptomatic cysts and cysts with a danger of impending rupture. Methods: We designed a coaxial catheter system to achieve concomitant evacuation of cyst contents while infusing scolicidal agent. Hypertonic saline is used to wash out cyst contents and to kill protoscolices. This was followed by injection of a sclerosant (ethyl alcohol 95%) into the residual cyst cavity to prevent formation of a cyst collection after the procedure. Seventeen cysts in 14 patients were successfully aspirated. Follow-up plain radiographs, ultrasonography and CT were performed weekly in the first 4 weeks and then at 3, 6 and 12 months for all patients. Seven patients (9 drained cysts) were followed up for 2 years and 1 patient for 3 years. Results: All cysts were successfully aspirated. The following morphologic changes were noticed: a gradual decrease in cyst size (17 cysts, 100%), thickening and irregularity of the cyst wall due to separation of endocyst from pericyst (7 cysts, 41%), development of a heterogeneous appearance of the cyst components (8 cysts, 47%) and development of pseudotumor (2 cysts, 12%). None of the treated cysts disappeared completely. No significant procedure-related complications were encountered. Conclusion: This modified PAIR technique is a reliable method for percutaneous treatment of risky and symptomatic hydatid cysts.

    Symptomatic cerebral vasospasm following an aneurysmal subarachnoid hemorrhage (SAH) is one of the major factors which cause morbidity and mortality of patients. The purpose of this study was to evaluate the effectiveness of intra-arterial nimodipine (IAN) infusion therapy in patients with symptomatic cerebral vasospasm. Between February 2005 and April 2011, fifty patients with symptomatic cerebral vasospasm following an aneurysmal SAH were treated with IAN infusion. After selective arterial catheterization, nimodipine was infused at a rate of 0.1 mg/min and a total of 2-3 mg per vessel was infused. We retrospectively reviewed the immediate angiographic results and clinical outcome at discharge. A grade of 5 and 4 in the Glasgow Outcome Scale (GOS) were considered favorable outcomes. In 50 patients, 117 procedures of IAN infusion (1-7; mean, 2.3)were done. After the treatment, immediate angiographic improvement was achieved in 113 (96.6%) of 117 procedures. No major complications occurred. At discharge, 38 (76%) patients showed a favorable clinical outcome in the GOS. IAN infusion therapy is safe and effective for the treatment of cerebral vasospasm following an aneurysmal SAH. However, the limitation is that repeated treatment is needed

    BACKGROUND AND AIMS: The influence of gender and age on risk factor prediction of coronary artery calcification (CAC) in symptomatic patients is unclear. METHODS: From the European Calcific Coronary Artery Disease (EURO-CCAD) cohort, we retrospectively investigated 6309 symptomatic patients, 62......, diabetes and smoking were independently predictive of CAC presence in both genders. In addition to a progressive increase in CAC with age, the most important predictors of CAC presence were dyslipidaemia and diabetes (β = 0.64 and 0.63, respectively) in males and diabetes (β = 1.08) followed by smoking (β...... = 0.68) in females; these same risk factors were also important in predicting increasing CAC scores. There was no difference in the predictive ability of diabetes, hypertension and dyslipidaemia in either gender for CAC presence in patients aged 70, only...

    Full Text Available Abstract Background Recently a new automatic device that measures brachial-ankle pulse wave velocity using an oscillometric method has been developed. However, the practical significance of brachial-ankle pulse wave velocity measurement remains uncertain. The purpose of this study was to examine the association between brachial-ankle pulse wave velocity and symptomatic cerebral infarction in patients with type 2 diabetes. Methods One thousand sixty six patients with type 2 diabetes were studied cross-sectionally. Measurements of brachial-ankle pulse wave velocity were made using the automatic device. Logistic regression analysis was used to calculate the odds ratio for cerebral infarction. Results The presence of symptomatic cerebral infarction was confirmed in 86 patients. In these patients brachial-ankle pulse wave velocity was found to be significantly higher than in patients without cerebral infarction (18.94 ± 4.95 versus 16.46 ± 3.62 m/s, p Conclusion Overall, we conclude that an increase in brachial-ankle pulse wave velocity is associated with symptomatic cerebral infarction in patients with type 2 diabetes.

    New media technologies (computers, mobile phones and the internet) have the potential to transform the healthcare information needs of patients with breast disease (Ferlay et al. in Eur J Cancer 49:1374-1403, 2013). However, patients' current level of use and their willingness to accept new media for education and communication remain unknown. This was a single-centre clinic-based prospective cross-sectional study. A previously developed instrument was modified, validated and tested on patients attending a symptomatic breast clinic. The instrument was evaluated on 200 symptomatic breast patients. The commonest outlets for education were staff (95 %), leaflets (69 %) and websites (59 %). Websites are more likely to be consulted by younger patients (higher education were more likely to favour apps, websites and email (p technology use among breast patients is expanding as expected along generational trends. As such its' further integration into healthcare systems can potentially ameliorate patient education and communication.

    The operation for isolated, stenotic, and symptomatic kinking of the internal carotid artery is safe and effective in preventing stroke and relieving the symptoms of cerebral ischemia. A consecutive sample clinical study with a mean follow-up of 44 months. The surgical department of an academic tertiary care center and an affiliated secondary care center. Fifty-four patients with a mean age of 67 years underwent 55 revascularizations of the internal carotid artery. The surgical procedures consisted of the following: shortening and reimplantation in the common carotid artery in 36 cases, bypass grafting in 15 cases, and transposition into the external carotid artery in 4 cases. Cumulative survival, primary patency, and stroke-free and neurologic symptom-free rates expressed by standard life-table analysis. No patients died in the postoperative period. The postoperative stroke rate was 1.8%. The cumulative rates (SEs) at 5 years were as follows: survival, 70% (10.2%); primary patency, 89% (7.8%); overall stroke free, 92% (6.8%); ipsilateral stroke free, 96% (5.3%); neurologic symptom free, 90% (7.5%); and ipsilateral symptom free, 93% (6.5%). Revascularization of the internal carotid artery for the treatment of isolated, stenotic, and symptomatic kinking is safe and effective in preventing stroke and relieving symptoms of cerebrovascular insufficiency.

    A subpopulation of patients with pancreas divisum experience symptomatic events such as recurrent acute pancreatitis and chronic pancreatitis. Minor papilla sphincterotomy has been reported as being an effective treatment. The aim of this study was to evaluate the safety and efficacy of endoscopic balloon dilation for the minor papilla. Between 2000 and 2012, 16 patients were retrospectively included in this study. After endoscopic balloon dilation for the minor papilla was received, a pancreatic stent or a nasal pancreatic drainage catheter was placed for 1 week. If a stricture or obstruction was evident, it was treated with balloon dilation followed by long-term stent placement (1 year). When an outflow of pancreatic juice was disturbed by a pancreatic stone, endoscopic stone extraction was performed. Balloon dilation and stent placement were achieved and were successful in all the cases (16/16; 100%). Clinical improvement was achieved in 7 (84.7%) of the 9 patients with recurrent acute pancreatitis and in 6 (85.7%) of the 7 patients with chronic pancreatitis. Early complications were observed in 1 (6.3%) patient. Pancreatitis or bleeding related to balloon dilation was not observed. Endoscopic balloon dilation for the minor papilla is feasible for the management of symptomatic pancreas divisum.

    Babesia microti, an intraerythrocytic parasite, has been implicated in transfusion transmission. B. microti seroprevalence in Connecticut (CT) blood donors is approximately 1%; however, it is not known what percentage of donors is parasitemic and poses a risk for transmitting infection. Therefore, we determined the prevalence of demonstrable B. microti DNA in donors from a highly endemic area of CT and compared observed rates with concurrent immunofluorescence assay (IFA) testing results. Blood samples from consenting donors in southeastern CT were collected from mid-August through early October 2009 and tested by IFA for immunoglobulin G antibodies and real-time polymerase chain reaction (PCR) for B. microti DNA. IFA specificity was determined using blood donor samples collected in northwestern Vermont (VT), an area nonendemic for Babesia. Of 1002 CT donors, 25 (2.5%) were IFA positive and three (0.3%) were real-time PCR positive. Among the three real-time PCR-positive donors, two were also IFA positive, while one was IFA negative and may represent a window period infection. The two IFA- and real-time PCR-positive donors appeared to subsequently clear infection. The other real-time PCR-positive donor did not provide follow-up samples. Of 1015 VT donors tested by IFA, only one (0.1%) was positive, but may have acquired infection during travel to an endemic area. We prospectively identified several real-time PCR-positive blood donors, including an IFA-negative real-time PCR-positive donor, in an area highly endemic for B. microti. These results suggest the need to include nucleic acid testing in planned mitigation strategies for B. microti. © 2013 American Association of Blood Banks.

    This study was designed to investigate the responsible region and the symptomatic flow and metabolism threshold for Broca's aphasia. Regional cerebral blood flow (CBF) and oxygen metabolism (CMRO 2 ) were measured by positron emission tomography (PET) using 15 O steady state method in eight patients with Broca's aphasia due to cerebral infarction and thirty patients without aphasia. During scanning, patients closed their eyes and were kept free from any stimuration. X-CT scan revealed abnormal low density in Broca's area which includes cortex and subcortex in the anterior region to Sylvian fissure in three patients with aphasia. In the other five patients with aphasia X-CT scan showed no abnormal low density in Broca's area, showed it in basal ganglionic region and subcortex. PET study revealed reduction of CBF and CMRO 2 in Broca's area in all cases with Broca's aphasia. CBF and CMRO 2 of Broca's area of aphasic patients were compared to those of non aphasic patients to obtain the symptomatic threshold in CBF and CMRO 2 . The values of symptomatic threshold were 20 - 27 ml/100 g/min in CBF and 2.0 ml/100 g/min in CMRO 2 . The symptomatic threshold differed from the threshold for development of abnormal low density on X-CT, therefore the measurement of CBF and CMRO 2 were useful in studying the responsible region for aphasia.

    Endophytes colonize an ecological niche similar to that of phytopathogens, which make them candidate for disease suppression. Anthracnose is a disease caused by Colletotrichum spp., a phytopathogen that can infect guarana (Paullinia cupana), an important commercial crop in the Brazilian Amazon. We investigated the diversity of endophytic bacteria inhabiting the phyllosphere of asymptomatic and symptomatic anthracnose guarana plants. The PCR-denaturation gradient gel electrophoresis (PCR-DGGE) fingerprints revealed differences in the structure of the evaluated communities. Detailed analysis of endophytic bacteria composition using culture-dependent and 16S rRNA clone libraries revealed the presence of Firmicutes, Proteobacteria, Actinobacteria, Bacteroidetes, and Acidobacteria phyla. Firmicutes comprised the majority of isolates in asymptomatic plants (2.40E(-4)). However, cloning and sequencing of 16S rRNA revealed differences at the genus level for Neisseria (1.4E(-4)), Haemophilus (2.1E(-3)) and Arsenophonus (3.6E(-5)) in asymptomatic plants, Aquicella (3.5E(-3)) in symptomatic anthracnose plants, and Pseudomonas (1.1E(-3)), which was mainly identified in asymptomatic plants. In cross-comparisons of the endophytic bacterial communities as a whole, symptomatic anthracnose plants contained higher diversity, as reflected in the Shannon-Weaver and Simpson indices estimation (P anthracnose can restructure endophytic bacterial communities by selecting certain strains in the phyllosphere of P. cupana. The understanding of these interactions is important for the development of strategies of biocontrol for Colletotrichum.

    Full Text Available Stressors can trigger binge-eating but researchers have yet to consider their effects on both neural responses to food cues and food consumption among those at risk. In this experiment, we examined the impact of acute stressors on neural activation to food images and subsequent food consumption within binge-eating disorder (BED and non-eating disordered control groups. Eighteen women meeting DSM-IV BED criteria and 26 women serving as non-eating disordered controls were randomly assigned to unpleasant stressor (painful cold pressor test followed by negative performance feedback or less unpleasant stressor (non-painful sensory discrimination task followed by positive performance feedback conditions. Subsequently, they were scanned with functional magnetic resonance imaging (fMRI while viewing food and neutral images. After the scans, participants completed a self-report battery in an environment conducive to snacking. During exposure to food images, BED-symptomatic women in the unpleasant stressor condition reported more liking of high calorie food images and showed less activation in one inhibitory area, the hippocampus, compared to controls in this condition. BED-symptomatic women exposed to unpleasant stressors also consumed more chocolate than any other group during the post-scan questionnaire completion. Crucially, reduced hippocampal activation to high calorie food images predicted more chocolate consumption following fMRI scans within the entire sample. This experiment provides initial evidence suggesting unpleasant acute stressors contribute to reduced inhibitory region responsiveness in relation to external food cues and later food consumption among BED-symptomatic women.

  14. The MOX Fuel Behaviour Test IFA-597.4: Temperature And Pressure Data To A Burn-Up Of 5.4 MWd/kg MOX

    1998-02-01

    Characterising the behaviour of MOX fuel is becoming increasingly important as many commercial reactors are or will be operating with this type of fuel. With this as a driving force, a new joint programme experiment, IFA-597.4, has been loaded into the reactor at Halden for the purpose of establishing the fission gas release behaviour of MOX fuel. Both annular and solid pellet fuel is being utilised and the irradiation is being conducted such that the fuel is initially operated below the onset of fission gas release. The fuel will later be subjected to small power up ratings which will be held for short periods of time. These are designed to bring the fuel to just above the temperature threshold for fission gas release thus allowing the FGR behaviour of both solid and annular MOX fuel to be established. The rig contains two fuel rods of active length 220 mm and diameter 8.05 mm. Both fuel rods contain MOX fuel with an initial Pu-fissile content of 6.07% and both are instrumented with a fuel centre thermocouple and a pressure transducer. The test is being performed under HBWR conditions and at the time of the reactor shutdown at the end of 1997 a mean burn-up of 5.4 MWd/kg MOX had been achieved with the rods at an average rating of 30 kW/m. The rod pressure data show that no fission gas had been released up to the shutdown. The fuel centre temperatures of both rods exhibit an initial increase concurrent with a fall in the monitored rod internal pressures as a result of fuel densification. It was estimated that about 1-1.4% fuel densification by volume had occurred in the two rods by a burn-up of about 3 MWd/kg MOX. (author)

    Peripheral artery disease (PAD), a diffuse manifestation of atherothrombosis, is a major cardiovascular threat. Although platelets are primary mediators of atherothrombosis, their role in the pathogenesis of PAD remains unclear. The authors sought to investigate the role of platelets in a cohort of symptomatic PAD. The authors profiled platelet activity, mRNA, and effector roles in patients with symptomatic PAD and in healthy controls. Patients with PAD and carotid artery stenosis were recruited into ongoing studies (NCT02106429 and NCT01897103) investigating platelet activity, platelet RNA, and cardiovascular disease. Platelet RNA sequence profiling mapped a robust up-regulation of myeloid-related protein (MRP)-14 mRNA, a potent calcium binding protein heterodimer, in PAD. Circulating activated platelets were enriched with MRP-14 protein, which augmented the expression of the adhesion mediator, P-selectin, thereby promoting monocyte-platelet aggregates. Electron microscopy confirmed the firm interaction of platelets with monocytes in vitro and colocalization of macrophages with MRP-14 confirmed their cross talk in atherosclerotic manifestations of PAD in vivo. Platelet-derived MRP-14 was channeled to monocytes, thereby fueling their expression of key PAD lesional hallmarks and increasing their directed locomotion, which were both suppressed in the presence of antibody-mediated blockade. Circulating MRP-14 was heightened in the setting of PAD, significantly correlated with PAD severity, and was associated with incident limb events. The authors identified a heightened platelet activity profile and unraveled a novel immunomodulatory effector role of platelet-derived MRP-14 in reprograming monocyte activation in symptomatic PAD.

    To report the long-term multicenter experience with retrograde intrarenal holmium-laser incision (RIR-HoLI) in the management of symptomatic renal sinus cysts (RSCs). In the literature, RIR-HoLI has been shown to be a safe and effective treatment, but there are only a few reports regarding long-term results and reproducibility of this procedure. From June 2010 to June 2015, 14 patients with symptomatic RSCs underwent RIR-HoLI. The mean age was 52.1 ± 11.28 years (range 28-77) and the mean cyst size was 53.2 ± 14.23 mm (range 35-90). In all cases, contrast-enhanced computer tomography (CT) showed compression of the renal pelvis by the cyst (no malignancy). Surgical outcome was assessed in terms of symptoms improvement (measured by Visual Analogue Scale [VAS] for pain) and renal ultrasound findings at 3-6-12 months postoperatively and then yearly. CT scan was carried out at 12 months follow-up. RIR-HoLI was successful in all patients. The mean operative time was 47.8 ± 13.54 min (range 30-80) and mean hospital stay was 3.5 days (range 2-5). There were 2 Clavien grade II complications (flank pain and urgency delaying discharge). After surgery, all patients -became asymptomatic (VAS score change, p = 0.0001). One patient had persistence of a small cyst (10 mm). Mean follow-up is 44 ± 17.24 months (range 24-84); all patients remained asymptomatic, with no signs of recurrence. RIR-HoLI proved to be a safe and effective treatment for symptomatic RSCs. In our experience, it provided excellent long-term results and was reproducible at 4 different -institutions. © 2018 S.

    Objectives Symptomatic neurological complications (NC) are a major cause of mortality in infective endocarditis (IE) but the impact of asymptomatic complications is unknown. We aimed to assess the impact of asymptomatic NC (AsNC) on the management and prognosis of IE. Methods From the database of cases collected for a population-based study on IE, we selected 283 patients with definite left-sided IE who had undergone at least one neuroimaging procedure (cerebral CT scan and/or MRI) performed as part of initial evaluation. Results Among those 283 patients, 100 had symptomatic neurological complications (SNC) prior to the investigation, 35 had an asymptomatic neurological complications (AsNC), and 148 had a normal cerebral imaging (NoNC). The rate of valve surgery was 43% in the 100 patients with SNC, 77% in the 35 with AsNC, and 54% in the 148 with NoNC (p<0.001). In-hospital mortality was 42% in patients with SNC, 8.6% in patients with AsNC, and 16.9% in patients with NoNC (p<0.001). Among the 135 patients with NC, 95 had an indication for valve surgery (71%), which was performed in 70 of them (mortality 20%) and not performed in 25 (mortality 68%). In a multivariate adjusted analysis of the 135 patients with NC, age, renal failure, septic shock, and IE caused by S. aureus were independently associated with in-hospital and 1-year mortality. In addition SNC was an independent predictor of 1-year mortality. Conclusions The presence of NC was associated with a poorer prognosis when symptomatic. Patients with AsNC had the highest rate of valve surgery and the lowest mortality rate, which suggests a protective role of surgery guided by systematic neuroimaging results. PMID:27400273

    We reviewed cases of osteosynthesis for symptomatic ulnar styloid nonunion. Since 1998, 13 cases of ulnar styloid nonunion have been treated by osteosynthesis. The patients were 10 men and 3 women, with a mean age of 27 years (range 11-65). The nonunion site was located in the middle in one case, in the base in 8 cases, and in the epiphyseal region in 4 cases. Osteosynthesis was performed with tension band wiring in all cases, and cancellous bone graft was performed in 12 of 13 cases. Distal radioulnar joint (DRUJ) instability was found by radiograph or CT in four cases; in two of these, osteosynthesis alone did not improve DRUJ instability and additional DRUJ stabilization was performed. One patient whose treatment failed to correct nonunion did not seek further treatment. In another case, an additional surgery was performed 1 week after the initial surgery to correct displacement of the fragment. The mean follow-up period was 15 months (range 8-45 months). According to Hauck's criteria, final pain was evaluated as excellent in nine cases, good in three cases, including the case resulting in nonunion, and fair in one case. (author)

    The aim of this study is to perform imaging of irises of different colors using spectral domain anterior segment optical coherence tomography angiography (AS-OCTA) and iris fluorescein angiography (IFA) and compare their effectiveness in examining iris vasculature. This is a cross-sectional observational clinical study. Patients with no vascular iris alterations and different pigmentation levels were recruited. Participants were imaged using OCTA adapted with an anterior segment lens and IFA with a confocal scanning laser ophthalmoscope (cSLO) adapted with an anterior segment lens. AS-OCTA and IFA images were then compared. Two blinded readers classified iris pigmentation and compared the percentage of visible vessels between OCTA and IFA images. Twenty eyes of 10 patients with different degrees of iris pigmentation were imaged using AS-OCTA and IFA. Significantly more visible iris vessels were observed using OCTA than using FA (W = 5.22; p Iris pigmentation was negatively correlated to the percentage of visible vessels in both imaging methods (OCTA, rho = - 0.73, p iris vasculature. In both AS-OCTA and IFA, iris pigmentation caused vasculature imaging blockage, but AS-OCTA provided more detailed iris vasculature images than IFA. Additional studies including different iris pathologies are needed to determine the most optimal scanning parameters in OCTA of the anterior segment.

    To assess the diagnostic accuracy of contrast-enhanced spectral mammography (CESM), and gauge its "added value" in the symptomatic setting. A retrospective multi-reader review of 100 consecutive CESM examinations was performed. Anonymised low-energy (LE) images were reviewed and given a score for malignancy. At least 3 weeks later, the entire examination (LE and recombined images) was reviewed. Histopathology data were obtained for all cases. Differences in performance were assessed using receiver operator characteristic (ROC) analysis. Sensitivity, specificity, and lesion size (versus MRI or histopathology) differences were calculated. Seventy-three percent of cases were malignant at final histology, 27% were benign following standard triple assessment. ROC analysis showed improved overall performance of CESM over LE alone, with area under the curve of 0.93 versus 0.83 (p<0.025). CESM showed increased sensitivity (95% versus 84%, p<0.025) and specificity (81% versus 63%, p<0.025) compared to LE alone, with all five readers showing improved accuracy. Tumour size estimation at CESM was significantly more accurate than LE alone, the latter tending to undersize lesions. In 75% of cases, CESM was deemed a useful or significant aid to diagnosis. CESM provides immediately available, clinically useful information in the symptomatic clinic in patients with suspicious palpable abnormalities. Radiologist sensitivity, specificity, and size accuracy for breast cancer detection and staging are all improved using CESM as the primary mammographic investigation.

    To evaluate patient-perceived benefits from receiving Reiki at a cancer infusion center. During a 6-month period, adults at a university hospital receiving Reiki through volunteer services were invited to complete a survey asking about perceived changes after Reiki. Changes in pain, mood, distress, sleep, and appetite were rated on a 5-point scale from no benefit to great benefit. Surveys were distributed after completing treatment and were returned in postage-paid envelops. A total of 145 surveys were completed (34.5% response rate), with 47 participants seen in the cancer infusion center and 98 in other areas of the hospital. Reiki was rated as a positive experience by 94% at the cancer center and 93% of others, with 92% at the cancer center and 86% of others interested in receiving additional Reiki sessions. Symptomatic improvement was similar for people at the cancer center and others, respectively, with much to great improvement for 89% and 86% for relaxation, 75% and 75% for anxiety/worry, 81% and 78% for improved mood, 43% and 35% for improved sleep, 45% and 49% for reduced pain, 38% and 43% for reduced isolation/loneliness, 75% and 63% for improved attitude, and 30% and 30% for improved appetite. Response was unaffected by previous exposure to Reiki, massage, or other touch therapy. Reiki results in a broad range of symptomatic benefits, including improvements in common cancer-related symptoms.

    2016-03-01

    The aim of the present study was to document the role of ultrasound in the diagnosis and management of symptomatic hydronephrosis during pregnancy. In this study, we reviewed 36 consecutive cases of pregnant women whose pregnancy was complicated by symptomatic hydronephrosis. In all patients, management was initially conservative (analgesics and fluids) after hospitalization. The following criteria were used to indicate double-J stent placement under US guidance rather than a conservative treatment: persistent pain with no improvement after conservative treatment, progressive hydronephrosis (>2 cm dilatation of the renal pelvis) or presence of uterine contractions. The mean patient's age was 25 years (17-35) and gestational age at clinical presentation was 24 weeks (13-37). 81 % of cases had a renal pelvis dilatation >2 cm, while in only 19 % of cases there was a hydronephrosis between 1 and 2 cm in diameter; however, calculi were confirmed only in 25 patients. 28 patients required an invasive management with double-J stent insertion under US guidance. The sensitivity and specificity of US in the etiological diagnosis of hydronephrosis during pregnancy was 83 and 91 %, respectively. Conservative management with medical therapy and observation should be the first-line treatment approach. In our opinion a rapid ureteral decompression with the insertion of a ureteral double-J stent, under US visualization, is the safest method in the treatment of pregnant women with obstructed renal systems.

    The purposes of this study were to compare the quality of life (QOL) of subjects who had untreated symptomatic hallux valgus with the QOL of the general population and to investigate factors associated with the QOL of the subjects. One hundred sixteen subjects with previously untreated and symptomatic hallux valgus were surveyed. QOL was assessed using the 36-item Short Form Health Survey (SF-36). Additionally, clinical evaluations (the visual analog scale for pain, Japanese Society for Surgery of the Foot Scale, lesser toe pain, and pain in other parts of the body) and radiographic evaluations (hallux valgus angle, intermetatarsal angle between the first and second metatarsals, and dislocation of the second metatarsophalangeal joint) were performed. Differences in the SF-36 between the subjects and the general population were tested using independent t tests. Correlations between the QOL measurements, clinical evaluations, and radiographic evaluations were assessed using Spearman rank correlation coefficient. All SF-36 subscales and physical component summary scores for the subjects were significantly lower than those of the general population. Notably, the standardized physical function subscale (38.2 ± 15.8, P hallux valgus subjects was lower than that of the general population. All QOL and clinical evaluation parameters were not significantly or negligibly correlated with the severity of toe deformities. Surgical decision making should not be based on the severity of the deformity alone, but rather patient QOL should also be carefully assessed. Level III, comparative series. © The Author(s) 2016.

    To investigate the impact of endoscope-assisted microsurgical fenestration on temporal arachnoid cysts, and to determine the advantages and limitations of the technique. Twenty-five children with symptomatic temporal arachnoid cysts were operated via eyebrow supraorbital keyhole microsurgical fenestration targeting the medial cyst wall. Preoperative magnetic resonance imaging (MRI) of the brain was done for all patients. Preoperative clinical presentation of the patients included headache (80%), nausea & vomiting (64%), drug resistant epilepsy (52%), macrocephaly (12%) papilledema (28%), motor weakness in the form of right-sided hemiparesis (12%) and cranial nerve palsy. Postoperative complete subsidence of headache was noted in 50%, while 20% remained unchanged. Drug resistant epilepsy improved in 69% of the patients. Postoperative MRI showed initial decrease in cyst volume as early as 3 months, only in a range of 5-12% volume reduction, and the late follow-up done at 6 and 18 months continued to show further reduction reported to be significant (p CSF) collection was the most common complication (20%). Only 1 patient experienced CSF leak mandating cysto-peritoneal shunting. Conclusıon: Eyebrow supraorbital keyhole microsurgical fenestration for temporal arachnoid cysts can be performed with a fairly low risk of complications and yields a favorable improvement in clinical and neuroimaging outcomes.

    Helicobacter pylori is a principal cause of chronic gastritis (CG), gastric and duodenal ulcers and a major risk factor for gastric cancer in humans. The objective of this study was to determine and compare the prevalence of H. pylori by different detection methods in symptomatic patients of Karachi. A total of 227 biopsy samples were collected from patients having complaints of peptic ulcer disease (PUD), chronic gastritis and/or abdominal discomfort (AD) from three different health providing institutions of Karachi during 2004- 2006 and analyzed for the presence of H. pylori. Comparative evaluation of three different conventional diagnostic techniques with that of a highly specific PCR amplification of ureC gene were carried out and found H. pylori in 62.5%, 64.7%. 68.7% and 59% by PCR, histology, rapid urease test and culture respectively. Out of 227 biopsy samples collected, 120 (52.8%) were H. pylori positive by all methods comprising 62 male patients and 58 female patients. A significant association between H. pylori infection and gastro duodenal diseases was observed. Among 120 H. pylori infected patients 56 were comprised of PUD, 37 with CG, 19 with AD and 8 with Gastric cancer (GCa). The epidemiology of H. p)1/ori infection is also discussed. (author)

    Hypotension occurs in 20% of hemodialysis procedures. To study the effects of midodrine on hypotension during hemodialysis. Ten patients on chronic hemodialysis and with a history of hypotension during the procedure, were studied. They received midodrine 10 mg per os or placebo during 5 dialytic procedures each, in a double blind cross over design. Blood pressure levels prior to dialysis were similar during the midodrine or placebo administration periods. During dialysis, systolic blood pressure fell 19.3 +/- 28 mmHg with midodrine and 23.4 +/- 28 mmHg with placebo. Diastolic blood pressure fell 7.3 +/- 11.5 mmHg with midodrine and 11.1 +/- 12 mmHg with placebo. The reduction in median arterial pressure was also less pronounced with midodrine. Midodrine lessens the fall in arterial pressure during hemodialysis, in patients with symptomatic hypotension.

    Full Text Available Our aim is to describe a case of acromegaly that was associated with symptomatic Rathke′s cyst. We describe a young male student without any significant family history who presented with clinical and biochemical features consistent with growth hormone excess, which was confirmed with dynamic testing. He also described a persistent headache predating symptoms of growth hormone excess by 4 years. Magnetic resonance imaging (MRI of the pituitary showed a large sellar mass which was thought to be a somatotroph adenoma. Trans-sphenoidal surgery was performed; however, a colloid lesion was identified by the neurosurgeon that proved to be a Rathke′s cyst. The association of acromegaly with Rathke′s cyst is very rare, with less than 10 cases found to be reported on review of literature. This is the first report from India.

    To evaluate the palliative role of radiotherapy (RT) and define the effectiveness of chemotherapy combined with palliative RT (CCRT) in patients with a symptomatic pelvic mass of metastatic colorectal cancer. From August 1995 to December 2007, 80 patients with a symptomatic pelvic mass of metastatic colorectal cancer were treated with palliative RT at Samsung Medical Center. Initial presenting symptoms were pain (68 cases), bleeding (18 cases), and obstruction (nine cases). The pelvic mass originated from rectal cancer in 58 patients (73%) and from colon cancer in 22 patients (27%). Initially 72 patients (90%) were treated with surgery, including 64 complete local excisions; 77% in colon cancer and 81% in rectal cancer. The total RT dose ranged 8-60 Gy (median: 36 Gy) with 1.8-8 Gy per fraction. When the α/β for the tumor was assumed to be 10 Gy for the biologically equivalent dose (BED), the median RT dose was 46.8 Gy 10 (14.4-78). Twenty one patients (26%) were treated with CCRT. Symptom palliation was assessed one month after the completion of RT. Symptom palliation was achieved in 80% of the cases. During the median follow-up period of five months (1-44 months), 45% of the cases experienced reappearance of symptoms; the median symptom control duration was five months. Median survival after RT was six months. On univariate analysis, the only significant prognostic factor for symptom control duration was BED ≥40 Gy 10 (p < 0.05), and CCRT was a marginally significant factor (p = 0.0644). On multivariate analysis, BED and CCRT were significant prognostic factors for symptom control duration (p < 0.05). RT was an effective palliation method in patients with a symptomatic pelvic mass of metastatic colorectal cancer. For improvement of symptom control rate and duration, a BED ≥ 40 Gy 10 is recommended when possible. Considering the low morbidity and improved symptom palliation, CCRT might be considered in patients with good performance status

    Calcium and phosphorus regulatory hormones may contribute to the pathogenesis of calcium nephrolithiasis. However, there has been no prospective study to date of plasma hormone levels and risk of kidney stones. This study aimed to examine independent associations between plasma levels of 1,25-dihydroxyvitamin D (1,25[OH]2D), 25-hydroxyvitamin D, 24,25-dihydroxyvitamin D, fibroblast growth factor 23 (FGF23), parathyroid hormone, calcium, phosphate, and creatinine and the subsequent risk of incident kidney stones. This study was a prospective, nested case-control study of men in the Health Professionals Follow-Up Study who were free of diagnosed nephrolithiasis at blood draw. During 12 years of follow-up, 356 men developed an incident symptomatic kidney stone. Using risk set sampling, controls were selected in a 2:1 ratio (n=712 controls) and matched for age, race, and year, month, and time of day of blood collection. Baseline plasma levels of 25-hydroxyvitamin D, 24,25-dihydroxyvitamin D, parathyroid hormone, calcium, phosphate, and creatinine were similar in cases and controls. Mean 1,25(OH)2D and median FGF23 levels were higher in cases than controls but differences were small and statistically nonsignificant (45.7 versus 44.2 pg/ml, P=0.07 for 1,25[OH]2D; 47.6 versus 45.1 pg/ml, P=0.08 for FGF23). However, after adjusting for body mass index, diet, plasma factors, and other covariates, the odds ratios of incident symptomatic kidney stones in the highest compared with lowest quartiles were 1.73 (95% confidence interval, 1.11 to 2.71; P for trend 0.01) for 1,25(OH)2D and 1.45 (95% confidence interval, 0.96 to 2.19; P for trend 0.03) for FGF23. There were no significant associations between other plasma factors and kidney stone risk. Higher plasma 1,25(OH)2D, even in ranges considered normal, is independently associated with higher risk of symptomatic kidney stones. Although of borderline statistical significance, these findings also suggest that higher FGF23 may be

    To (1) determine the incidence of symptomatic venous thromboembolic events (VTEs) after knee arthroscopy and arthroscopy-assisted procedures at a single institution and (2) determine associated risk factors for VTEs in these patients. The records of patients who underwent knee arthroscopy at a single institution between 1988 and 2008 were reviewed. Chemoprophylaxis was not routinely used. Confirmed VTEs occurring within 4 weeks after the index arthroscopy procedure were included. A 2:1 matched control group was generated to include patients in whom knee arthroscopy was performed by the same surgeon either on the same day or immediately before each case resulting in a VTE. Preoperative and perioperative data were collected with respect to demographic data, medical history, medications, and surgical and anesthesia data. Univariate and multivariate analyses were performed. During the study period, 12,595 patients underwent knee arthroscopy. Among these patients, 43 cases of VTEs (35 deep venous thromboses [DVTs], 5 pulmonary embolisms [PEs], and 3 DVTs that progressed to PEs) occurred, resulting in an incidence of 0.30% (95% confidence interval [CI], 0.22% to 0.41%) for DVT, 0.06% (95% CI, 0.03% to 0.12%) for PE, and 0.34% (95% CI, 0.25% to 0.46%) for VTEs overall. Factors associated with an elevated risk of symptomatic postoperative VTEs included a history of malignancy (P = .01; odds ratio [OR], 6.3), a history of VTEs (P = .02; OR, 5.2), or the presence of more than 2 classic risk factors for VTEs (P = .01; OR, 13.6). In this study, symptomatic VTEs were rare and occurred infrequently, with an incidence of 0.34% (95% CI, 0.25% to 0.46%), after knee arthroscopy and arthroscopy-assisted cases in the absence of routine chemoprophylaxis. Patients with a history of VTEs, a history of malignancy, or 2 or more classic risk factors are at increased risk of VTEs after knee arthroscopy, and chemoprophylaxis should be considered in these select patients.

    Primary closure after carotid endarterectomy (CEA) has been much maligned as an inferior technique with worse outcomes than in patch closure. Our purpose was to compare perioperative and long-term results of different CEA closure techniques in a large institutional experience. A consecutive cohort of CEAs between January 1, 2000, and December 31, 2010, was retrospectively analyzed. Closure technique was used to divide patients into three groups: primary longitudinal arteriotomy closure (PRC), patch closure (PAC), and eversion closure (EVC). End points were perioperative events, long-term strokes, and restenosis ≥70%. Multivariate regression models were used to assess the effect of baseline predictors. There were 1737 CEA cases (bilateral, 143; mean age, 71.4 ± 9.3 years; 56.2% men; 35.3% symptomatic) performed during the study period with a mean clinical follow-up of 49.8 ± 36.4 months (range, 0-155 months). More men had primary closure, but other demographic and baseline symptoms were similar between groups. Half the patients had PAC, with the rest evenly distributed between PRC and EVC. The rate of nerve injury was 2.7%, the rate of reintervention for hematoma was 1.5%, and the length of hospital stay was 2.4 ± 3.0 days, with no significant differences among groups. The combined stroke and death rate was 2.5% overall and 3.9% and 1.7% in the symptomatic and asymptomatic cohort, respectively. Stroke and death rates were similar between groups: PRC, 11 (2.7%); PAC, 19 (2.2%); EVC, 13 (2.9%). Multivariate analysis showed baseline symptomatic disease (odds ratio, 2.4; P = .007) and heart failure (odds ratio, 3.1; P = .003) as predictors of perioperative stroke and death, but not the type of closure. Cox regression analysis demonstrated, among other risk factors, no statin use (hazard ratio, 2.1; P = .008) as a predictor of ipsilateral stroke and severe (glomerular filtration rate <30 mL/min/1.73 m(2)) renal insufficiency (hazard ratio, 2.6; P

    The aims of this study were to evaluate the immunomodulatory role of TGF-beta1, IL-10, and INF-gamma in spleen and liver extracts and supernatant cultures of white spleen cells from male symptomatic and asymptomatic dogs, naturally infected by Leishmania (Leishmania) chagasi. Thirty dogs from Araçatuba, São Paulo, Brazil, an endemic leishmaniosis area, were selected by positive ELISA serological reaction for Leishmania sp. and divided into two groups: asymptomatic (n=15) and symptomatic (n=15) consisting of animals with at least three characteristic signs (fever, dermatitis, lymphoadenopathy, onychogryphosis, weight loss, cachexia, locomotion problems, conjunctivitis, epistaxis, hepatosplenomegaly, edema, and apathy). After euthanasia, spleen and liver fragments were collected for ex vivo quantification of TGF-beta1, IL-10, and INF-gamma. Naturally active in vitro produced TGF-beta1 was also evaluated in spleen cell culture supernatant. Spleen and liver extract of asymptomatic dogs had higher mean TGF-beta1 levels than symptomatic dogs. High concentrations of IL-10 were found in spleen, and mainly in liver extract of both groups. Higher INF-gamma concentrations were found in spleen extracts of symptomatic dogs, and in liver extracts of asymptomatic dogs. Extract of this cytokine was lower in spleen extract. Although INF-gamma is being produced in canine infection, mean levels of TGF-beta1 and IL-10 from spleen and liver extracts were quantitatively much higher; suggesting that immune response in both asymptomatic and symptomatic dogs was predominantly type Th2.

    Full Text Available A 27-year-old previously healthy woman was admitted to the hospital with recurrent seizures. Status epilepticus developed that became refractory to third-line therapy with propofol and barbiturates. The patient had a very extensive diagnostic workup including autoimmune, viral and genetic investigations. A tentative immune therapy was proposed with high doses of steroids and plasma exchanges. Our patient had an inherited heterozygous single nucleotide variant in the sequence c.1280A>G [p.Lys427Arg] of the SMC3 gene that was insufficient to explain the seizures. Surprisingly, IgM antibodies against Japanese encephalitis virus were positive on the serum drawn 11 days after symptom onset, as detected by ELISA and the immunofluorescence antibody (IFA technique. IgG antibodies were also positive using the IFA technique, but not with ELISA. The same investigations as well as the detection of the viral genome by the q-RT-PCR technique were negative on cerebrospinal fluid. Despite the suspicion of a viral infection, we concluded that our patient had a new-onset refractory status epilepticus of cryptogenic origin. Termination of the status epilepticus was obtained after 47 days, with a possible benefit from the introduction of ketamine.

    We report a case of symptomatic hydronephrosis caused by transcaval penetration of a Bird's Nest filter. Perforation of the wall of the inferior vena cava (IVC) following insertion of a caval filter is a well-recognized complication. Whilst two cases of hydronephrosis have been described with Greenfield filters, no case involving a Bird's Nest filter has been reported previously

    When symptomatic gastroenterology patients have an indication for colonic imaging, clinicians have a choice between optical colonoscopy (OC) and computerized tomography colonography with three-dimensional reconstruction (3-D CTC). 3-D CTC provides a minimally invasive and rapid evaluation of the entire colon, and it can be an efficient modality for diagnosing symptoms. It allows for a more targeted use of OC, which is associated with a higher risk of major adverse events and higher procedural costs. A case can be made for 3-D CTC as a primary test for colonic imaging followed if necessary by targeted therapeutic OC; however, the relative long-term costs and benefits of introducing 3-D CTC as a first-line investigation are unknown. The aim of this study was to assess the cost effectiveness of 3-D CTC versus OC for colonic imaging of symptomatic gastroenterology patients in the UK NHS. We used a Markov model to follow a cohort of 100,000 symptomatic gastroenterology patients, aged 50 years or older, and estimate the expected lifetime outcomes, life years (LYs) and quality-adjusted life years (QALYs), and costs (£, 2010-2011) associated with 3-D CTC and OC. Sensitivity analyses were performed to assess the robustness of the base-case cost-effectiveness results to variation in input parameters and methodological assumptions. 3D-CTC provided a similar number of LYs (7.737 vs 7.739) and QALYs (7.013 vs 7.018) per individual compared with OC, and it was associated with substantially lower mean costs per patient (£467 vs £583), leading to a positive incremental net benefit. After accounting for the overall uncertainty, the probability of 3-D CTC being cost effective was around 60 %, at typical willingness-to-pay values of £20,000-£30,000 per QALY gained. 3-D CTC is a cost-saving and cost-effective option for colonic imaging of symptomatic gastroenterology patients compared with OC.

    Segmental instability represents one of several different factors that may cause or contribute to the failed back surgery syndrome after lumbar microdiscectomy. As segmental lumbar instability poses diagnostic problems by lack of clear radiological and clinical criteria, only little is known about the occurrence of this phenomenon following primary microdiscectomy. Retrospectively, the records of 2,353 patients were reviewed according to postoperative symptomatic segmental single-level instability after lumbar microdiscectomy between 1989 and 1997. Progressive neurological deficits increased (mean of 24 months; SD: 12, range 1-70) after the initial surgical procedure in 12 patients. The mean age of the four men and eight women was 43 years (SD: 6, range 40-77). The main symptoms and signs of secondary neurological deterioration were radicular pain in 9 of 12 patients, increased motor weakness in 6 of 12 patients and sensory deficits in 4 of 12 patients. All 12 symptomatic patients had radiological evidence of segmental changes correlating with the clinical symptoms and signs. All but one patient showed a decrease in the disc height greater than 30% at the time of posterior spondylodesis compared with the preoperative images before lumbar microdiscectomy. All patients underwent secondary laminectomy and posterior lumbar sponylodesis. Postoperatively, pain improved in 8 of 9 patients, motor weakness in 3 of 6 patients, and sensory deficits in 2 of 4 patients. During the follow-up period of 72+/-7 months, one patient required a third operation to alleviate spinal stenosis at the upper end of the laminectomy. Patients with secondary segmental instability following microdiscectomy were mainly in their 40s. Postoperative narrowing of the intervertebral space following lumbar microdiscectomy is correlated to the degree of intervertebral disc resection. It can therefore be concluded that (1) patients in their 40s are prone to postoperative narrowing of the intervertebral

    Full Text Available Neuronal circuit disturbances that lead to hyperexcitability in the cortico-hippocampal network are one of the landmarks of temporal lobe epilepsy. The dentate gyrus (DG network plays an important role in regulating the excitability of the entire hippocampus by filtering and integrating information received via the perforant path. Here, we investigated possible epileptogenic abnormalities in the function of the DG neuronal network in the Synapsin II (Syn II knockout mouse (Syn II-/-, a genetic mouse model of epilepsy. Syn II is a presynaptic protein whose deletion in mice reproducibly leads to generalized seizures starting at the age of two months. We made use of a high-resolution microelectrode array (4096 electrodes and patch-clamp recordings, and found that in acute hippocampal slices of young pre-symptomatic (3-6 weeks-old Syn II-/- mice excitatory synaptic output of the mossy fibers is reduced. Moreover, we showed that the main excitatory neurons present in the polymorphic layer of the DG, hilar mossy cells, display a reduced excitability. We also provide evidence of a predominantly inhibitory regulatory output from mossy cells to granule cells, through feed-forward inhibition, and show that the excitatory-inhibitory ratio is increased in both pre-symptomatic and symptomatic Syn II-/- mice. These results support the key role of the hilar mossy neurons in maintaining the normal excitability of the hippocampal network and show that the late epileptic phenotype of the Syn II-/- mice is preceded by neuronal circuitry dysfunctions. Our data provide new insights into the mechanisms of epileptogenesis in the Syn II-/- mice and open the possibility for early diagnosis and therapeutic interventions.

The authors enrolled 252 patients, who underwent CT colonogprahy.128 extra colonic findings was identified in 80 patients (31.74%). The average age was 65.62 years (SD = 12.7, min. age was 29, max. age. 85 years). According the clinical significance the extra colonic findings have been divided into three groups – low, moderate and very important extra colonic findings. Low significant findings were 68 (53.12%), moderate 26 (20.31%) and very important extra colonic findings were 34 (26.56%), of which 30 were malignant nature. (author)

  2. The Relationship Between Traumatic Brain Injury and Rates of Chronic Symptomatic Illness in 202 Gulf War Veterans.

    Although not a "signature injury" of Operation Desert Shield/Desert Storm (i.e., Gulf War, GW), some GW veterans have a history traumatic brain injury (TBI). For example, a previous study found that 12.2% of the GW veterans from the Fort Devens Cohort Study had self-reported TBIs. The present study sought to build upon this finding by examining the relationship between TBI and chronic symptomatic illness in a different sample of GW veterans. Participants were 202 GW veterans recruited from 2014 to 2018 at the San Francisco Veterans Affairs Medical Center as part of a VA-funded study on the effects of predicted exposure to low levels of sarin and cyclosarin on brain structure and function. The Ohio State University TBI identification method was used to determine lifetime history of TBI. The Kansas Gulf War Military History and Health Questionnaire was used to assess symptoms and to determine cases of Kansas Gulf War Illness (GWI) and Centers for Disease Control and Prevention (CDC) Chronic Multisymptom Illness (CMI). Nearly half (47%) the sample had a history of TBI, but only 7% of the TBIs were sustained in injuries that occurred during the GW. Most of the TBIs were sustained in injuries that occurred prior to (73%) or after (34%) the GW. History of TBI was not associated with higher rates of symptomatic illness when it was narrowly defined (i.e., Kansas GWI cases or cases of severe CMI). History of TBI was only associated with higher rates of symptomatic illness when it is broadly defined (i.e., CDC CMI or mild-moderate CMI). There was suggestive evidence that veterans who sustained TBIs during the GW (only seven in the present sample) have poorer functional outcomes compared with GW veterans with non-GW related TBIs. While TBIs were uncommon during the GW, many GW veterans sustained TBIs prior or after the GW. Because TBI and GWI/CMI share some overlapping symptoms, history of TBI may appear to be associated with increased rates of chronic symptomatic illness in

    Encephalocele is a rare condition that consists of herniation of cerebral matter through openings of dura and skull. A majority of encephaloceles are congenital and manifest in childhood. We present a case of a 45-year-old man presenting with contralateral hemiparesis and found to have an extremely rare phenomenon of a symptomatic posttraumatic parietal intradiploic encephalocele (IE) manifesting 36 years following pediatric traumatic head injury. Computed tomography and magnetic resonance imaging confirmed herniation of brain tissue into the intradiploic space. Surgical treatment with reduction of the encephalocele achieved near resolution of preoperative hemiparesis on follow-up. The pathogenesis and a literature review of IE are discussed. PMID:28316901

    The present literature review aimed to review the evidence for community-based distribution (CBD) of iron-folic acid (IFA) supplementation as a feasible approach to improve anaemia rates in low- and middle-income countries. The literature review included peer-reviewed studies and grey literature from PubMed, Cochrane Library, LILAC and Scopus databases. Low- and middle-income countries. Non-pregnant women, pregnant women, and girls. CBD programmes had moderate success with midwives and community health workers (CHW) who counselled on health benefits and compliance with IFA supplementation. CHW were more likely to identify and reach a greater number of women earlier in pregnancy, as women tended to present late to antenatal care. CBD channels had greater consistency in terms of adequate supplies of IFA in comparison to clinics and vendors, who faced stock outages. Targeting women of reproductive age through school and community settings showed high compliance and demonstrated reductions in anaemia. CBD of IFA supplementation can be a valuable platform for improving knowledge about anaemia, addressing compliance and temporary side-effects of IFA supplements, and increasing access and coverage of IFA supplementation. Programmatic efforts focusing on community-based platforms should complement services and information provided at the health facility level. Provision of training and supportive supervision for CHW on how to counsel women on benefits, side-effects, and when, why, and how to take IFA supplements, as part of behaviour change communication, can be strengthened, alongside logistics and supply systems to ensure consistent supplies of IFA tablets at both the facility and community levels.

    Fluid in the subacromial bursa (SAB) is a common finding on magnetic resonance (MR) images of the shoulder, and the implications of this finding have not been clarified. We retrospectively reviewed and correlated the MR features with arthroscopic findings in 21 symptomatic patients who had fluid in the SAB on MR imaging without demonstrable rotator cuff tear. Rotator cuff impingement was the most frequent surgical finding (42.9%). Other frequent surgical observations were glenbid labrum abnormality (28.6%), bursitis (19%), and supraspinatus tendinitis (14.3%). Distribution of acromial types was similar to that reported by Bigliani et al., and impingement was evenly distributed among acromial types in our study population. We conclude that in our patient population group the MR finding of isolated SAB fluid in symptomatic patients is highly likely to be associated with the finding of other abnormalities in the shoulder joint at surgery.

    Annual incidence of symptomatic adjacent level disease (ALD) following lumbar fusion surgery ranges from 0.6% to 3.9% per year. Sagittal malalignment may contribute to the development of ALD. To describe the relationship between pelvic incidence-lumbar lordosis (PI-LL) mismatch and the development of symptomatic ALD requiring revision surgery following single-level transforaminal lumbar interbody fusion for degenerative lumbar spondylosis and/or low-grade spondylolisthesis. All patients who underwent a single-level transforaminal lumbar interbody fusion at either L4/5 or L5/S1 between July 2006 and December 2012 were analyzed for pre- and postoperative spinopelvic parameters. Using univariate and logistic regression analysis, we compared the spinopelvic parameters of those patients who required revision surgery against those patients who did not develop symptomatic ALD. We calculated the predictive value of PI-LL mismatch. One hundred fifty-nine patients met the inclusion criteria. The results noted that, for a 1° increase in PI-LL mismatch (preop and postop), the odds of developing ALD requiring surgery increased by 1.3 and 1.4 fold, respectively, which were statistically significant increases. Based on our analysis, a PI-LL mismatch of >11° had a positive predictive value of 75% for the development of symptomatic ALD requiring revision surgery. A high PI-LL mismatch is strongly associated with the development of symptomatic ALD requiring revision lumbar spine surgery. The development of ALD may represent a global disease process as opposed to a focal condition. Spine surgeons may wish to consider assessment of spinopelvic parameters in the evaluation of degenerative lumbar spine pathology. Copyright © 2017 by the Congress of Neurological Surgeons

    Endoscopic ultrasonography-guided (EUS)-guided pancreatic interventions have gained increasing attention. Here we review EUS-guided pancreatic duct (PD) access techniques and outcomes. EUS-guided PD intervention is divided into two types, antegrade and rendezvous techniques, following EUS-guided pancreatography. In the antegrade technique, pancreaticoenterostomy is carried out by stent placement between the PD and the stomach, duodenum, or jejunum. Transenteric antegrade PD stenting is conducted by stent placement, advancing anteriorly into the PD through the pancreatic tract. The rendezvous technique is carried out by using a guidewire through the papilla or anastomotic site for retrograde stent insertion. In terms of EUS-guided PD stenting, 11 case reports totaling 75 patients (35 normal anatomy, 40 altered anatomy) have been published. The technical success rate was greater than 70%. Early adverse events, including severe hematoma and severe pancreatitis,occurred in seven (63.6%) of 11 reports. Regarding the rendezvous technique, 12 case reports totaling 52 patients (22 normal anatomy, 30 altered anatomy) have been published. The technical success rate ranged from 25% to 100%. It was 48% in one report that involved more than 20 cases. Once stents were placed, all patients became free of symptoms. Early mild adverse events occurred in four (36.4%) of 11 reports. In conclusion, although it can be risky because of possible serious or even fatal adverse events, including pancreatic juice leakage, perforation and severe acute pancreatitis, EUS-PD access seems to be promising for treating symptomatic pancreatic diseases caused by PD stricture and pancreaticoenterostomy stricture. © 2013 The Authors.

    The molecular pathways involved in the progression of intracranial large artery atherosclerosis (ILA) are largely unknown. Our objective was to prospectively study the relationship between circulating levels of inflammatory markers and fibrinolysis inhibitors, and the risk of progression of symptomatic ILA. Seventy-five consecutive patients with first-ever symptomatic intracranial atherostenosis were studied. Blood levels of C-reactive protein (CRP), E-selectin, monocyte chemoattractant protein-1, intercellular adhesion molecule-1, matrix metalloproteinases 1, 2, 3, 8, 9, 10, and 13, plasminogen activator inhibitor-1 (PAI-1), and lipoprotein(a) were measured 3 months after the qualifying stroke or transient ischemic attack. Thereafter, patients underwent long-term transcranial Doppler follow-up to detect progression of ILA. During a median follow-up time of 23 months, 25 (33%) patients showed ILA progression. Multivariable adjusted Cox regression models and Kaplan-Meier curves showed that high baseline level of CRP, E-selectin, intercellular adhesion molecule-1, matrix metalloproteinase 9, PAI-1, and lipoprotein(a) predicted ILA progression independently of vascular risk factors. Of them, only CRP (CRP>5.5 mg/L; HR, 5.4 [2.3 to 12.7]; P=0.0001) and PAI-1 (PAI-1>23.1 ng/mL; HR, 2.4 [1.0 to 5.8]; P=0.05) predicted ILA progression also independently of the other studied molecules. Progression of symptomatic ILA is associated with a proinflammatory state, as reflected by high levels of inflammatory markers, and with defective fibrinolysis, as indicated by raised concentrations of endogenous fibrinolysis inhibitors.

    Ranolazine is an antianginal agent that was approved in the EU in 2008 as an add-on therapy for symptomatic chronic angina pectoris treatment in patients who are inadequately controlled by, or are intolerant to, first-line antianginal therapies. These patients' quality of life is significantly affected by more frequent angina events, which increase the risk of revascularization. To assess the cost-utility of ranolazine versus placebo as an add-on therapy for the symptomatic treatment of patients with chronic angina pectoris in Spain. A decision tree model with 1-year time horizon was designed. Transition probabilities and utility values for different angina frequencies were obtained from the literature. Costs were obtained from Spanish official DRGs for patients with chronic angina pectoris. We calculated the incremental cost-utility ratio of using ranolazine compared with a placebo. Sensitivity analyses, by means of Monte Carlo simulations, were performed. Acceptability curves and expected value of perfect information were calculated. The incremental cost-utility ratio was €8,455 per quality-adjusted life-year (QALY) per patient in Spain. Sensitivity analyses showed that if the decision makers' willingness to pay is €15,000 per QALY, the treatment with ranolazine will be cost effective at a 95 % level of confidence. The incremental cost-utility ratio is particularly sensitive to changes in utility values of those non-hospitalized patients with mild or moderate angina frequency. Ranolazine is a highly efficient add-on therapy for the symptomatic treatment of chronic angina pectoris in patients who are inadequately controlled by, or intolerant to, first-line antianginal therapies in Spain.

    We developed MOX Fuel Database, which included valuable data from several irradiation tests in FUGEN and Halden reactor, for help of LWR MOX use. This database includes the data of fabrication and irradiation, and the results of post-irradiation examinations for seven fuel assemblies, i.e. P06, P2R, E03, E06, E07, E08 and E09, irradiated in FUGEN. The highest pellet peak burn-up reached ∼48GWd/t in MOX fuels, of which the maximum plutonium content was ∼6 wt%, irradiated in E09 fuel assembly without any failure. Also the data from the instrumented MOX fuels irradiated in HBWR to study the irradiation behavior of BWR MOX fuels under the steady state condition (IFA-514/565 and IFA-529), under the load-follow operation condition (IFA-554/555) and under the transit condition (IFA-591) are included in this database. The highest assembly burn-up reached ∼56 GWd/t in IFA-565 steady state irradiation test, and the maximum linear power of MOX fuel rods was 58.3-68.4 kW/m without any failure in IFA-591 ramp test. In addition, valuable instrument data, i.e. cladding elongation, fuel stack elongation, fuel center temperature and rod inner pressure were obtained from IFA-554/555 load-follow test. (author)

    Full Text Available The aim of the study was to investigate the effect of antenatal iron-folic acid (IFA supplementation on child stunting in Nepalese children age <2 years. A retrospective cohort study design was used, in which a pooled cohort of 5235 most recent live births 2 years prior to interview from three Nepal Demographic and Health Surveys (2001, 2006 and 2011 was analysed. The primary outcome was stunting in children age <2 years. The main exposure variable was antenatal IFA supplementation. Multivariate Poisson regression analysis was performed. In our sample, 31% and 10% of Nepalese children age <2 years were stunted and severely stunted, respectively. The adjusted relative risk of being stunted was 14% lower in children whose mothers used IFA supplements compared to those whose mothers did not use (aRR = 0.86, 95% CI = 0.77–0.97. Additionally, the adjusted relative risk of being stunted was significantly reduced by 23% when antenatal IFA supplementation was started ≤6 months with ≥90 IFA supplements used during pregnancy (aRR = 0.77, 95% CI = 0.64–0.92. Antenatal IFA supplementation significantly reduced the risk of stunting in Nepalese children age <2 years. The greatest impact on the risk reduction of child stunting was when IFA supplements were started ≤6 months with ≥90 supplements were used.

    We analysed the effect of irradiation of an enlarged spleen in some hematologic diseases: chronic myelaemia, osteomyelophybrosis and chronic lymphadenosis, where splenectomy had been contraindicated and where pain has been a leading symptom and also the discomfort because of an enlarged spleen. For 20 years in the Clinic of Radiotherapy have been treated 23 patients with the above mentioned diseases. We have irradiated all patients using X-ray and later- Co-60. To reach a palliative effect we have irradiated patients with single doses from 50 cGy to 100 cGy with an interval of 2-3 days between each fraction, but the total doses have been different- from 400 cGy to 1500 cGy. The enlarged spleen has reached the pelvis in 3 cm to 17 cm below the costal margin, and in some patients has crossed the median line of the body going in some centimetres on the other side. The reduction of splenic size and volume is as follows: full reduction in 6 patients (26.1%) and partial in 17 (73.9%). All patients resulted in decreases in pain and tension in abdomen and the total discomfort. No serious side haematologic effects were encountered. Our experience indicates that cautious splenic irradiation can be a safe and useful therapeutic alternative. The symptomatic palliation in patients, where splenectomy is not an option, is effective and is an additional alternative for an improvement of their general condition

    The functional imaging techniques of positron emission tomography (PET) and single photon emission tomography (SPET) have been used to study regional brain function in Huntington's disease (HD) in vivo. Reduced striatal glucose metabolism and dopamine receptor binding are evident in all symptomatic HD patients and in ∼50% of asymptomatic adult mutation carriers. These characteristics correlate with clinical measures of disease severity. Reduced cortical glucose metabolism and dopamine receptor binding, together with reduced striatal and cortical opioid receptor binding, have also been demonstrated in symptomatic patients with HD. Repeat PET measures of striatal function have been used to monitor the progression of this disease objectively. In the future, functional imaging will provide a valuable way of assessing the efficacy of both fetal striatal cell implants and putative neuroprotective agents, such as nerve growth factors.

    Acute symptomatic hyponatremia after thiazide diuretic initiation is a medical emergency. Here we describe the case of a flight attendant who developed acute hyponatremia during a flight and the potential risk factors for developing this condition. A 57-year-old flight attendant with history of essential hypertension was recently started on a thiazide diuretic. As she did routinely when working, she increased her water intake during a flight from London to Mexico City. She complained of nausea and headache during the flight. Upon arrival, she developed severe disorientation and presented to the hospital emergency room (ER) with a Glasgow scale of 12, hypoxia, and a generalized tonic clonic seizure. Her laboratory results on arrival were consistent with severe hyponatremia (serum Na 116 mEql/L) and severe cerebral edema by CT scan. She was treated with hypertonic saline, with complete resolution of the neurologic symptoms. We describe high water intake and hypoxia related to decreased partial pressure of oxygen in the cabin as the two main risk factors for thiazide-induced acute hyponatremia in this case.

    Full Text Available This study was carried out to evaluate the use of acridine orange fluorescence technique on blood slides as a rapid diagnostic test for tropical theileriosis in comparison with the Giemsa-stained thin blood film technique. Also the indirect fluorescent antibody test has been employed for the serodiagnosis of tropical theileriosis. The study was carried out on 62 young and 48 adult Friesian cattle suffering from clinical tropical theileriosis in Qassim Region, Central Saudi Arabia, during the period from August 2006 to July 2008. For control, blood samples were also obtained from 25 young and 25 adult, clinically healthy, Friesian cattle, selected at random from different dairy farms in Qassim Region. Thin blood films were fixed with methanol and stained with Giemsa and acridine orange and were examined by two independent microbiologists. There was 100% correlation in the interpretation of slides stained with Giemsa and acridine orange both with respect to positivity and negativity, between the two microbiologists. It is concluded that if facilities are available acridine orange is a valuable alternative for screening tropical theileriosis. The method may also have potential value in the diagnosis of Theileria parva, which causes East Coast fever, and also other Theileria species. Results of the present study also showed that IFA test was not found sufficiently sensitive and specific as has been reported earlier. [Vet. World 2011; 4(8.000: 341-344
