    s challenging environmental issues. The results also brought focus to the potential contributions that DOE’s science and technology could make for solving the many difficult, multi-generational problems faced by hundreds of bi-national communities along the 2,000-mile shared border of the United States and Mexico. Efforts to address these U.S.-Mexico border issues were initially sponsored by the DOE’s Albuquerque and Carlsbad offices. In subsequent years, the U.S. Congress directed appropriations to DOE’s Carlsbad office to address public health, safety and security issues prevalent within U.S.-Mexico border communities. With ASL’s assistance, DOE’s Albuquerque office developed contacts and formed partnerships with interested U.S and Mexican government, academic, and commercial organizations. Border industries, industrial effluents, and public health conditions were evaluated and documented. Relevant technologies were then matched to environmental problem sets along the border. Several technologies that were identified and subsequently supported by this effort are now operational in a number of U.S.-Mexico border communities, several communities within Mexico’s interior states, and in other parts of Latin America. As a result, some serious public health threats within these communities caused by exposure to toxic airborne pollutants have been reduced. During this time, DOE’s Carlsbad office hosted a bilateral conference to establish a cross-border consensus on what should be done on the basis of these earlier investigative efforts. Participating border region stakeholders set an agenda for technical collaborations. This agenda was supported by several Members of Congress who provided appropriations and directed DOE’s Carlsbad office to initiate technology demonstration projects. During the following two years, more than 12 private-sector and DOE-sponsored technologies were demonstrated in partnership with numerous border community stakeholders. All technologies

  9. The Common Factor of Bilateral U.S. Exchange Rates: What is it Related to?

    OpenAIRE

    Ponomareva, Natalia; Sheen, Jeffrey; Wang, Ben

    2015-01-01

    We identify a common factor driving a panel of fifteen monthly bilateral exchange rates against the U.S. dollar. We find this factor is closely related to U.S. nominal and real macroeconomic variables, financial market variables and commodity prices. Our results suggest this common factor is broadly related to the macroeconomic fundamentals in the Taylor rule and uncovered interest parity models. However, the set of fundamentals relevant to these models changes over time.

  10. Persistent profitability of technical analysis on foreign exchange markets?

    OpenAIRE

    L. MENKHOFF; M. SCHLUMBERGER

    1995-01-01

    The effect of technical analyses on the performance of subsequent policies and actions in the foreign exchange markets is analysed using three cases. Results show that use of technical analyses is persistently profitable. Participants, however, tend to view short-term market risk as important and thus decide to forego some of the rules derived from technical analysis. This observation does not negate the theory on efficient learning.

  11. 2011 PERFORMANCE ASSESSMENT COMMUNITY OF PRACTICE TECHNICAL EXCHANGE - SUMMARY

    Energy Technology Data Exchange (ETDEWEB)

    Seitz, R.

    2011-12-30

    The Performance Assessment Community of Practice (PA CoP) was developed in 2008 to improve consistency and quality in the preparation of performance assessments (PAs) and risk assessments across the Department of Energy (DOE) Complex. The term, PA, is used to represent all of these modeling applications in this report. The PA CoP goals are to foster the exchange of information among PA practitioners and to share lessons learned from PAs conducted for DOE, commercial disposal facilities, and international entities. Technical exchanges and workshops are a cornerstone of PA CoP activities. Previous technical exchanges have addressed Engineered Barriers (2009 - http://www.cresp.org/education/workshops/pacop/), the Advanced Simulation Capability for Environmental Management and the Cementitious Barriers Partnership (2010 - http://srnl.doe.gov/copexchange/links.htm). Each technical exchange also includes summary presentations regarding activities at DOE, the Nuclear Regulatory Commission (NRC) and other organizations (e.g., International Atomic Energy Agency (IAEA)) as well as a number of presentations from selected sites to provide insight and perspective from on-going modeling activities. Through the deployment of PA Assistance Teams, the PA CoP has also been engaged in the development of new PAs across the DOE Complex. As a way of improving consistency in the preparation of new PAs, the teams provide technical advice and share experiences, noteworthy practices, and lessons learned from previous Low-Level Waste Disposal Facility Federal Review Group (LFRG) reviews. Teams have provided support for PAs at Hanford, Idaho, Paducah and Portsmouth. The third annual PA CoP Technical Exchange was held on May 25-26, 2011 in Atlanta, GA. The PA CoP Steering Committee Meeting held its first meeting on May 24 prior to the Technical Exchange. Decision making using models and software quality assurance were the topical emphasis for the exchange. A new feature at the 2011 technical

    International Nuclear Information System (INIS)

    Moak, D.J.; Wendling, M.A.

    1995-02-01

    May 15--21, 1994, the first technical conference was held at Hanford between Ukraine-Chornobyl, Westinghouse Hanford, and SAIC, to exchange technical information and experience gained in cleanup and stabilization of radioactive contamination at Hanford and Chornobyl. Protocol was signed for a second exchange and technology demonstration program in Kiev and near Chornobyl power plants. Technical Exchange No. 2 was held from August 28--September 9, 1994, with 3 focus areas: field demonstration of DOE-Hanford technologies and application to cleanup of contaminated lands resulting from 1986 Chornobyl accident; application of other US DOE-technologies; and observation/evaluation of Ukraine-developed technologies for potential application in USA. Three radiological mapping systems were demonstrated near Chornobyl: man-carried Ultrasonic Ranging and Data System, a mobile radiological data system, and NOMAD field gamma spectroscopy system. The Ukraine-Chornobyl team hosted technical presentations, discussions and field trips for 4.5 days, providing insight on the Chornobyl problem and allowing the US team to present overviews on DOE technologies that may be applicable to the Chornobyl situation. It is concluded that Ukrainian scientists have tremendous talent and expended considerable energy in attempting to tackle such a problem, but economic and cultural conditions with Ukraine have prevented them from acquiring the resources to implement basic aspects of characterization and remediation activities. Most of their publications are in Russian only. Their translation, plus resources to carry out proposals for bench scale and field demonstration projects, could benefit the DOE complex and other nuclear programs. The considerable cultural and economic change occurring in Ukraine, is providing opportunities for private industries to assist in the changes and for DOE, others to apply cleanup technologies, and it is essential that close institutional relations be established

  18. On the use of exchange rates as trading rules in a bilateral system of transferable discharge permits

    International Nuclear Information System (INIS)

    Rodriguez, F.

    2000-01-01

    The use of a system of transferable discharge permits to control the harmful effects of non-uniformly mixed pollutants requires the application of trading rules in order to prevent permit trading among sources from violating environmental standards. The elements and properties of bilateral trading rules can be analyzed more easily once formulated as exchange rates, which would convert, in a cost-effective way, the emission right potentially given up by the seller into an offsetting emission right acquired by the buyer. In this article, a new expression for such exchange rates is proposed and then analyzed to infer some unexplored properties of the system. 8 refs

    Full text: According to a memorandum of understanding between Germany and the Netherlands, the NDKK has to review the existing communication methods. Proceeding from this review proposals have to be developed to improve the bilateral communication and data exchange in case of events near the German-Dutch border and more generally for every event involving nuclear facilities. The NDKK has established a working group for reviewing and working out the proposals. Members of the working group are federal institutions resp. state institutions. Within their scope of duties are emergency management and communication, data collection and communication and expert advice to stakeholders. On the Dutch side the National Institute for Public Health and the Environment (RIVM) takes part, on the German side, the Federal Office for Radiation Protection (BfS) and the Lower Saxony State Agency for Ecology (NLOE) are involved. At international level, the ECURIE (European Community Urgent Radiological Information Exchange, system of the EU) and EMERCON (Emergency Convention, system of the IAEA) are used for early notification and subsequent messaging. The designated contact points and competent authorities are VROM (Ministry of Housing, Spatial Planning and the Environment) and BMU (German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety). According to a bilateral agreement, there is an additional direct communication for emergency notification between BMU and VROM. For the exchange of radiological measurement data the EURDEP standard (European Radiological Data Exchange Platform) is applied. In addition to the multinational procedure, it has been decided to exchange data directly in order to make the exchange faster and redundant. Presently, data are exchanged on a weekly basis by ftp, using EURDEP 2.0 format. The only NPP located near the Dutch-German border is the German NPP Emsland (KKE) close to the town of Lingen.

    Osteopetrosis is a rare inherited skeletal disorder characterized by increased density. The increased fragility of such dense bone results in a greater incidence of fractures, especially around hip and proximal femur. The surgical treatment of such fractures is difficult due to hard but brittle structure of bone. Herein we report a case of bilateral subtrochanteric fracture in an osteopetrotic patient. It was fixed using a dynamic hip screw with plate.

    2007-01-01

    An exchange rate between two currencies can be materially affected by shocks emerging from a third country. A US demand shock, for example, can affect the exchange rate between the euro and the yen. Since positive US demand shocks have a greater positive impact on Japanese interest rates than on eurozone rates, the yen appreciates against the euro in response. Using quarterly data on the U.S., the euro area and Japan from 1981 to 2006, this paper shows that the third-currency effects are sign...

    1985-07-01

    As the U. S. Department of Energy (DOE) and DOE contractors have increased the magnitude and scope of their cooperative activities with other nations in the nuclear fuel cycle and waste management field, a need has developed for ready sources of information concerning foreign waste management programs, DOE technology exchange policies, bilateral fuel cycle and waste management agreements and plans and activities to implement those agreements. The INFX (International InLormation E~change) Guide is one of a series of documents that have been prepared to provide that information. The INFX Guide has been compiled under the charter of PNL's International Support Office (IPSO) to maintain for DOE a center to collect, organize, evaluate and disseminate information on foreign and international radioactive waste management programs. Because the information in this document is constantly subject to change, the document is assembled in loose-leaf form to accommodate frequent updates.

    Mohit Sharma

    2017-01-01

    Full Text Available Introduction: This article deals with two patients who underwent bilateral hand transplantation following amputation of both upper limbs at the distal third of the foream. Materials and Methods: The first patient had a history of loss of hands in a train accident , with possiblity of a run over element during the injury. The second patient lost his both hands in a mine blast. The preoperative work up included detailed clinical and psychological evaluation. The donor retrieval was similar in both the cases and the donors were housed in our own instittution. The donor preparation, recipient preparation and the transplant procedure was similar except for the need of primary tendon transfers in the left hand of the first patient. Results: The first patient needed a free flap transfer to cover compromised skin flap on the left hand on the second day. The second hand transplant was uneventful. Both the recipients are now back to their normal daily routines. Conclusions: Hand transplantation is a potentially life altering procedure, but to optimise the results, it is imperative that there is a meticulous planning and diligent execution with utmost importance to the detail coupled with a synchronised team effort.

    1987-02-01

    The feasibility of a chemical exchange method for the separation of the isotopes of europium was demonstrated in the system EuCl 2 -EuCl 3 . The single stage separation factor, α, in this system is 1.001 or 1.0005 per mass unit. This value of α is comparable to the separation factors reported for the U 4+ - U 6 and U 3+ - Y 4+ systems. The separation of the ionic species was done by precipitation of the Eu 2+ ions or by extraction of the Eu 3+ ions with HDEHP. Conceptual schemes were developed for a countercurrent reflux cascades consisting of solvent extraction contractors. A regenerative electrocel, combining simultaneous europium reduction, europium oxidation with energy generation, and europium stripping from the organic phase is described. 32 refs., 22 figs., 6 tabs

    The United States and Russia are dismantling nuclear weapons and generating hundreds of tons of excess plutonium and high enriched uranium fissile nuclear materials that require disposition. The U.S. Department of Energy and Russian Minatom organizations.are planning and implementing safe, secure storage and disposition operations for these materials in numerous facilities. This provides a new opportunity for technical exchanges between Russian and Western scientists that can establish an improved and sustained common safety culture for handling these materials. An initiative that develops and uses personal relationships and joint projects among Russian and Western participants involved in fissile nuclear materials safety management contributes to improving nuclear materials nonproliferation and to making a safer world. Technical exchanges and workshops are being used to systematically identify opportunities in the nuclear fissile materials facilities to improve and ensure the safety of workers, the public, and the environment

    Data on plasma exchange therapy in the intensive care unit (ICU) setting are scarce. We aimed to describe the technical aspects and the adverse events associated with the procedure in critically ill patients. All adult patients treated by plasma exchange in the medical ICU of the Saint-Louis university hospital between January 1, 2013 and March 31, 2015 were prospectively included. We report on 260 plasma exchange procedures performed in 50 patients. The centrifugation technique was used for 159 (61%) procedures and the filtration technique for the other 101 (39%) procedures. Both techniques had similar efficacy to treat hyperviscosity syndrome (n = 18). Seventy (26.9%) of the 260 plasma exchange procedures were reported with at least one adverse reaction. Centrifugation and filtration techniques had similar rates of adverse reactions (23.9 vs. 31.7%, P = .19). Hypotension was the most reported (n = 21, 8%) and correlates with a low hematocrit before therapy. Most complications were related to allergic reactions to the replacement fluids. Coagulation disorders depended on the type of replacement fluid. The post-exchange fibrinogen level was decreased by 54% [48;66] with albumin 5%, and 4% [-5;17] with plasma frozen within 24 h. Twenty-three (22.8%) of the 101 filtration procedures experienced filter clotting. Filter clotting was associated with a higher volume exchange prescribed when compared to procedures without filter clotting (4600 [4000;5000] ml vs. 3900 [3600;4800] ml, P < .01). Plasma exchange is a relatively safe and generally well-tolerated procedure in the ICU setting. Most adverse events are unpredictable and related to minor allergic reactions. © 2017 Wiley Periodicals, Inc.

    During FY13, the INL developed an advanced SMR PRA framework which has been described in the report Small Modular Reactor (SMR) Probabilistic Risk Assessment (PRA) Detailed Technical Framework Specification, INL/EXT-13-28974 (April 2013). In this framework, the various areas are considered: Probabilistic models to provide information specific to advanced SMRs Representation of specific SMR design issues such as having co-located modules and passive safety features Use of modern open-source and readily available analysis methods Internal and external events resulting in impacts to safety All-hazards considerations Methods to support the identification of design vulnerabilities Mechanistic and probabilistic data needs to support modeling and tools In order to describe this framework more fully and obtain feedback on the proposed approaches, the INL hosted a technical exchange meeting during August 2013. This report describes the outcomes of that meeting.

    Although technical trading rules have been widely used by practitioners in financial markets, their profitability still remains controversial. We here investigate the profitability of moving average (MA) and trading range break (TRB) rules by using the Shanghai Stock Exchange Composite Index (SHCI) from May 21, 1992 through December 31, 2013 and Shenzhen Stock Exchange Component Index (SZCI) from April 3, 1991 through December 31, 2013. The t-test is adopted to check whether the mean returns which are conditioned on the trading signals are significantly different from unconditioned returns and whether the mean returns conditioned on the buy signals are significantly different from the mean returns conditioned on the sell signals. We find that TRB rules outperform MA rules and short-term variable moving average (VMA) rules outperform long-term VMA rules. By applying White's Reality Check test and accounting for the data snooping effects, we find that the best trading rule outperforms the buy-and-hold strategy when transaction costs are not taken into consideration. Once transaction costs are included, trading profits will be eliminated completely. Our analysis suggests that simple trading rules like MA and TRB cannot beat the standard buy-and-hold strategy for the Chinese stock exchange indexes.

    Full Text Available This study estimates the exchange rate pass-through into domestic prices in Indonesia in the two-stage approach. The study focuses on first step pass-through, i.e. ERPT into import prices and second step pass-through, i.e. into consumer prices, using cointegration and error-correction mechanism (ECM model. This research uses a Zivot-Andrews technique to test for structural breaks and Gregory-Hansen models to tests. The results show that the long run ERPT to import prices with structural breaks is relatively low compared to the results without them. The absolut error correction term values resulted from cointegration are decreased and the error-correction models need period lagged longer than one-period if the estimation included the estimated structural breaks. The main finding is that allowing for possible breaks around the crises in Indonesia, and a shift of the exchange rate management from managed to free floating in 1997 helps to restore a long run cointegration relationship estimation.

    As health care providers adopt and make “meaningful use” of health information technology (health IT), communities and delivery systems must set up the infrastructure to facilitate health information exchange (HIE) between providers and numerous other stakeholders who have a role in supporting health and care. By facilitating better communication and coordination between providers, HIE has the potential to improve clinical decision-making and continuity of care, while reducing unnecessary use of services. When implemented as part of a broader strategy for health care delivery system and payment reform, HIE capability also can enable the use of analytic tools needed for population health management, patient engagement in care, and continuous learning and improvement. The diverse experiences of seven communities that participated in the three-year federal Beacon Community Program offer practical insight into factors influencing the technical architecture of exchange infrastructure and its role in supporting improved care, reduced cost, and a healthier population. The case studies also document challenges faced by the communities, such as significant time and resources required to harmonize variations in the interpretation of data standards. Findings indicate that their progress developing community-based HIE strategies, while driven by local needs and objectives, is also influenced by broader legal, policy, and market conditions.

    ONC-approved state plans for HIE were reviewed for descriptions and depictions of statewide HIE technical architecture. Review was complicated by non-standard organizational elements and technical terminology across state plans. Findings were mapped to industry standard, referenced, and defined HIE architecture descriptions and characteristics. Results are preliminary due to the initial subset of ONC-approved plans available, the rapid pace of new ONC-plan approvals, and continuing advancements in standards and technology of HIE, etc. Review of 28 state plans shows virtually all include a direct messaging component, but for participating entities at state-specific levels of granularity (RHIO, enterprise, organization/provider). About ½ of reviewed plans describe a federated architecture, and ¼ of plans utilize a single-vendor "hybrid-federated" architecture. About 1/3 of states plan to leverage new federal and open exchange technologies (DIRECT, CONNECT, etc.). Only one plan describes a centralized architecture for statewide HIE, but others combine central and federated architectural approaches.

    Finland has made both multilateral and bilateral agreements on the exchange of information related to radiation safety. The first arrangements for international agreements and exchange of information were made after the Chernobyl accident. In 1987, Finland joined the convention on early notification of a nuclear power accident coordinated by International Atomic Energy Agency. The convention is applied to accidents that cause of may cause emissions of radioactive substances that might affect the radiation safety of another country. Besides the convention on early notification, some other individual agreements have also been made. These include the International Nuclear Event Scale (INES) system and power companies own information exchange systems. Finland has conducted bilateral agreements with the Nordic countries and the Soviet Union on the notification of accidents and exchange of nuclear power plant information. Today, Russia answers for the Soviet Union's contractual obligations. (orig.)

    Bilateral torticollis is a very rare form of a well known deformity i.e. muscular torticollis. This malformation might present a differential diagnostic problem both for orthopaedic surgeons and ophthalmologists, as well as, for neurologists. In agreement with the literature, the role of an injury during labour or defective embriogenesis is suggested to play a part.

    Ion specimens can be incorporated in glasses or natural clays by ionic exchange process with different concentrations dependent of matrix's type and of the ionic exchange parameters. In particular, the incorporation of silver ions presents high interest by its biocidal properties. A compound contending ion silver specimens presents bactericidal and fungicidal properties with effect proportional to ion concentration. This work presents results about application of the atomic absorption technical to determine the silver ion concentration incorporated in a glass matrix by ionic exchange process. The ionic exchange experiments were realized with different AgNO 3 concentration and constant temperature. After ionic exchange process, the glass samples were submitted to characterization by Energy Dispersive X-Ray Spectroscopy and Atomic Absorption Techniques. The comparative results between different techniques showed that atomic absorption technical is adequate to determine ion silver concentration incorporated in the glass matrix after ionic exchange process.

    In this article, we use the Japanese candlesticks, a method popular in the technical analysis of the Stock/Forex markets and apply it to a variable in physics-the solar activity. This method is invented and used exclusively for economic analysis and its application to a physical problem produced unexpected results. We found that the Japanese candlesticks are convenient tool in the analysis of the variables in the physics of the Sun. Based on our observations, we differentiated a new cycle in the solar activity.

    1995-01-01

    Technologies are being developed by the US Department of Energy's (DOE) Savannah River Site (SRS) in conjunction with the Electric Power Research Institute (EPRI) and the commercial sector to convert low-level radioactive ion exchange (IEX) resin wastes from the nuclear utilities to solid stabilized waste forms for permanent disposal. One of the alternative waste stabilization technologies is vitrification of the resin into glass. Wastes can be vitrified at elevated temperatures by thermal treatment. One alternative thermal treatment is conventional Joule heated melting. Vitrification of wastes into glass is an attractive option because it atomistically bonds both hazardous and radioactive species in the glass structure, and volume reduces the wastes by 70-80%. The large volume reductions allow for large associated savings in disposal and/or long term storage costs

    The geothermal heat exchanger transfers heat geothermal heat through the metal wall of the outer pipe to the circulating water. The clean water heats up on its way down and is then pumped up again through the insulated inner riser pipe. The heated water is used for district heating. Drilling started on 26 March 1994, and the system was commissioned on 10 November 1994. Today, it supplies heat and warm water to about 1100 apartments. During its first year of operation the Prenzlau geothermal heat exchanger, which is 2800 m deep, covered more than 20 % of the heat demand of the Prenzlau-West district heating grid. The seasonal performance factor in continuous operation of the 500 kW system is between 8 and 12 % of the weather-dependent peak load, with hourly peaks of more than 700 kW.

    The potential for expanded communication among researchers, scholars, and students is supported by growth in the capabilities for electronic communication as well as expanding access to various forms of electronic interchange and computing capabilities. Increased possibilities for information exchange, collegial dialogue, collaboration, and access to remote resources exist as high-speed networks, increasingly powerful workstations, and large, multi-user computational facilities are more frequently linked and more commonly available. Numerous writers speak of the telecommunications revolution and its impact on the development and dissemination of knowledge and learning. One author offers the phrase 'Scholarly skywriting' to represent a new form of scientific communication that he envisions using electronic networks. In the United States (U.S.), researchers associated with the National Science Foundation (NSF) are exploring 'nationwide collaboratories' and 'digital collaboration.' Research supported by the U.S. National Aeronautics and Space Administration (NASA) points to a future where workstations with built-in audio, video monitors, and screen sharing protocols are used to support collaborations with colleagues located throughout the world. Instruments and sensors located worldwide will produce data streams that will be brought together, analyzed, and distributed as new findings. Researchers will have access to machines that can supply domain-specific information in addition to locator and directory assistance. New forms of electronic journals will emerge and provide opportunities for researchers and scientists to exchange information electronically and interactively in a range of structures and formats. Ultimately, the wide-scale use of these technologies in the dissemination of research results and the stimulation of collegial dialogue will change the way we represent and express our knowledge of the world. A new paradigm will evolve--perhaps a truly worldwide

    Immediately after the Chernobyl accident most European countries established or enhanced their national radioactivity monitoring and information systems. The large transboundary effect of the radioactive release also triggered the need for bilateral and international agreements on the exchange of radiological information in case of a nuclear accident. Based on the experiences gained from existing bi- and multilateral data exchange the Commission of the European Communities has made provision for and is developing technical systems to exchange information of common interest. Firstly the existing national systems and systems based on bilateral agreements are summarized. The objectives and technical realizations of the EC international information exchange systems ECURIE and EURDEP, are described. The experiences gained over the past few years and the concepts for the future, in which central and eastern European countries will be included, are discussed. The benefits that would result from improving the international exchange of radiological information in the event of a future nuclear accident are further being described

    Between 1905 and 1934 over 869 farmers in Owens Valley, California sold their land and associated water rights to Los Angeles, 250 miles to the southwest. This agriculture-to-urban water transfer increased Los Angeles' water supply by over 4 times, making the subsequent dramatic growth of the semi-arid city possible, generating large economic returns. The exchange took water from a marginal agricultural area and transferred it via the Los Angeles Aqueduct. No other sources of water became ava...

    Several Member countries of the Nuclear Energy Agency of the Organisation for Economic Co-operation and Development (OECD/NEA) have established the International Common-Cause Failure Data Exchange Project (ICDE Project) to encourage multilateral co-operation in the collection and analysis of data relating to Common-Cause Failure (CCF) events. The objectives of the ICDE Project are to: a) Collect and analyse CCF events over the long term so as to better understand such events, their causes, and their prevention; b) Generate qualitative insights into the root causes of CCF events which can then be used to derive approaches or mechanisms for their prevention or for mitigating their consequences; c) Establish a mechanism for the efficient feedback of experience gained in connection with CCF phenomena, including the development of defences against their occurrence, such as indicators for risk based inspections; and d) Record event attributes to facilitate quantification of CCF frequencies when so decided by the Project Working Group. The ICDE Project is envisaged to comprise all possible events of interest, including both complete and partial ICDE events. The ICDE Project will cover the key components of the main safety systems. Presently, the components listed below are included in the ICDE Project. Data have been collected for the six first components in the list: Centrifugal pumps, Diesel generators, Motor operated valves, Safety relief valves/power operated relief valves, Check valves, Batteries, Level measurement, Breakers, Control rod drive assemblies. Others will be added to this list later on. In this component coding guidelines, explanations on the ICDE General coding format are given. The guide reflects present experience with the data format and with the collected data. Further interpretations and clarifications will be added, should they become necessary. For each component analysed in the ICDE project, separate coding guidance is provided in the appendices

    This paper shows examples of technical assistance programmes within bilateral cooperation agreements between the Federal Republic of Germany and a number of developing countries of very different characteristics and summarizes the possibilities of technical assistance granted by international organizations, such as IAEA, UNDP, etc. A basic requirement for a successful transfer of technology is a high knowledge level of the indigenous scientists and engineers. Therefore, programmes for training and education and for information exchange are presented. Based on these, the means and methods of planning, performance and quality assurance are explained by practical examples and are related to the progress achieved in the use of nuclear energy and in establishing a national industry in the developing countries.

    1981-07-01

    When enriching the light uranium isotope U-235 according to the separation nozzle method, UF 6 and light auxiliary gas (H 2 ) must be separated from each other at the head as well as at the shoulder of the cascade. After pre-separation at a special separation nozzle stage, fine separation is planned by means of a low-temperature separator made as a compact heat exchanger. This report describes first testing under process conditions of a representative section of the separator blocks intended for technical-scale operation. It is proved that the rated loading capacity is attained while the residual UF 6 concentration contained in the escaping hydrogen can be lowered down to values less than 1 ppm. It is further shown that the requirement of constant pressure drop at the separator, which is decisive for the smooth interplay of preseparator stage and low-temperature separator, can be imposed by direct control of the supply of the refrigerating medium through the variable to be kept constant. A concept of control is proposed for industrial application necessitating the operation of several low-temperature separators staggered in terms of time. This concept allows the relatively simple optimum utilization of the separator capacity even under variable operating conditions. (orig.) [de

    The classical technical analysis methods of financial time series based on the moving average and momentum is recalled. Illustrations use the IBM share price and Latin American (Argentinian MerVal, Brazilian Bovespa and Mexican IPC) market indices. We have also searched for scaling ranges and exponents in exchange rates between Latin American currencies ($ARS$, $CLP$, $MXP$) and other major currencies $DEM$, $GBP$, $JPY$, $USD$, and $SDR$s. We have sorted out correlations and anticorrelations of such exchange rates with respect to $DEM$, $GBP$, $JPY$ and $USD$. They indicate a very complex or speculative behavior.

    STUDY DESIGN.: Retrospective clinical data analysis. OBJECTIVE.: To investigate and verify our philosophy of spontaneous slip reduction following circumferential release via bilateral minimally invasive transforaminal lumbar interbody fusion (Mini-TLIF) for treatment of low-grade symptomatic isthmic spondylolisthesis. SUMMARY OF BACKGROUND DATA.: Symptomatic isthmic spondylolisthesis usually requires surgical intervention, and the most currently controversial focus is on method and degree of reduction; and Mini-TLIF is an attractive surgical procedure for isthmic spondylolisthesis. METHODS.: Between February 2004 and June 2008, 21 patients with low-grade isthmic spondylolisthesis underwent Mini-TLIF in our institute. Total resection of the scar around the pars interarticularis liberated the nerve roots, achieving posterior release as well. The disc was thoroughly resected, and the disc space was gradually distracted and thoroughly released with sequential disc shavers until rupture of anulus conjunct with anterior longitudinal ligament, accomplishing anterior release, so as to insert Cages. Because of circumferential release, the slipped vertebrae would tend to obtain spontaneous reduction, and with pedicle screw fixation, additional reduction would be achieved without any application of posterior translation force. Radiographs, Visual Analogue Scale, and Oswestry Disability Index were documented. All the cases were followed up for 10 to 26 months. RESULTS.: Slip percentage was reduced from 24.2% ± 6.9% to 10.5% ± 4.0%, and foraminal area percentage increased from 89.1% ± 3.0% to 93.6% ± 2.1%. Visual Analogue Scale and Oswestry Disability Index decreased from 7.8 ± 1.5 to 2.1 ± 1.1 and from 53.3 ± 16.2 to 17.0 ± 7.8, respectively. No neurologic complications were encountered. There were no signs of instrumentation failure. The fusion rate approached 100%. CONCLUSION.: Slip reduction is based on circumferential release. The procedure can be well performed

    Full Text Available OBJECTIVES: Technical complications are a known hazard in veno-venous extracorporeal membrane oxygenation (vvECMO. Identifying these complications and predictive factors indicating a developing system-exchange was the goal of the study. METHODS: Retrospective study on prospectively collected data of technical complications including 265 adult patients (Regensburg ECMO Registry, 2009-2013 with acute respiratory failure treated with vvECMO. Alterations in blood flow resistance, gas transfer capability, hemolysis, coagulation and hemostasis parameters were evaluated in conjunction with a system-exchange in all patients with at least one exchange (n = 83. RESULTS: Values presented as median (interquartile range. Patient age was 50(36-60 years, the SOFA score 11(8-14.3 and the Murray lung injury Score 3.33(3.3-3.7. Cumulative ECMO support time 3411 days, 9(6-15 days per patient. Mechanical failure of the blood pump (n = 5, MO (n = 2 or cannula (n = 1 accounted for 10% of the exchanges. Acute clot formation within the pump head (visible clots, increase in plasma free hemoglobin (frHb, serum lactate dehydrogenase (LDH, n = 13 and MO (increase in pressure drop across the MO, n = 16 required an urgent system-exchange, of which nearly 50% could be foreseen by measuring the parameters mentioned below. Reasons for an elective system-exchange were worsening of gas transfer capability (n = 10 and device-related coagulation disorders (n = 32, either local fibrinolysis in the MO due to clot formation (increased D-dimers [DD], decreased platelet count; n = 24, or device-induced hyperfibrinolysis (increased DD, decreased fibrinogen [FG], decreased platelet count, diffuse bleeding tendency; n = 8, which could be reversed after system-exchange. Four MOs were exchanged due to suspicion of infection. CONCLUSIONS: The majority of ECMO system-exchanges could be predicted by regular inspection of the complete ECMO circuit, evaluation of gas exchange, pressure drop

    For the promotion of research exchanges on global environmental preservation with developing countries, Ms. Malee Santikunaporn, lecturer of Faculty of Engineering, Thammasat University, Bankok, Thailand was invited. Desulfurization/denitrification facilities, which are being widely spread in developed countries, have marked effects, but high prices are an obstacle to the spread in developing countries. To make them spread in developing countries, it is needed to develop the technology which is low in price and meets the actual state in developing countries. As a technology with high viability, a system to simultaneously remove SOx and NOx was cited in which Cu is used as catalyst and adsorbent and into which the catalyst regeneration process is integrated. Considering it, technical exchanges on Cu-SiO{sub 2} catalyst as the basic theme were made during September 26 - December 23, 1999. Through visits on and exchanges with Tokyo Institute of Technology, ICEET, University of Kyoto, etc., understanding was deepened about how each country is tackling environmental problems. The theme 'Oxidative sorption of SO2 by Cu-SiO{sub 2} catalyst: characteristics of catalyst' could deepen knowledge/information of the developmental research as a system for simultaneous removal of SOx/NOx. The data obtained indicated great practicality of Cu-SiO{sub 2}. (NEDO)

    2015-03-15

    Highly tritiated water (HTW) may be generated at ITER by various processes and, due to the excessive radio toxicity, the self-radiolysis and the exceedingly corrosive property of HTW, a potential hazard is associated with its storage and process. Therefore, the capture and exchange method for HTW utilizing Molecular Sieve Beds (MSB) was investigated in view of adsorption capacity, isotopic exchange performance and process parameters. For the MSB, different types of zeolite were selected. All zeolite materials were additionally coated with platinum. The following work comprised the selection of the most efficient zeolite candidate based on detailed parametric studies during the H{sub 2}/D{sub 2}O laboratory scale exchange experiments (about 25 g zeolite per bed) at the Tritium Laboratory Karlsruhe (TLK). For the zeolite, characterization analytical techniques such as Infrared Spectroscopy, Thermogravimetry and online mass spectrometry were implemented. Followed by further investigation of the selected zeolite catalyst under full technical operation, a MSB (about 22 kg zeolite) was processed with hydrogen flow rates up to 60 mol*h{sup -1} and deuterated water loads up to 1.6 kg in view of later ITER processing of arising HTW.

    Cochlear implants (CI) are standard for the hearing rehabilitation of severe to profound deafness. Nowadays, if bilaterally indicated, bilateral implantation is usually recommended (in accordance with German guidelines). Bilateral implantation enables better speech discrimination in quiet and in noise, and restores directional and spatial hearing. Children with bilateral CI are able to undergo hearing-based hearing and speech development. Within the scope of their individual possibilities, bilaterally implanted children develop faster than children with unilateral CI and attain, e.g., a larger vocabulary within a certain time interval. Only bilateral implantation allows "binaural hearing," with all the benefits that people with normal hearing profit from, namely: better speech discrimination in quiet and in noise, as well as directional and spatial hearing. Naturally, the developments take time. Binaural CI users benefit from the same effects as normal hearing persons: head shadow effect, squelch effect, and summation and redundancy effects. Sequential CI fitting is not necessarily disadvantageous-both simultaneously and sequentially fitted patients benefit in a similar way. For children, earliest possible fitting and shortest possible interval between the two surgeries seems to positively influence the outcome if bilateral CI are indicated.

    2016-09-01

    The study addresses the effectiveness of using ion exchange substrates (IES) to optimize mineral nutrition of plants grown in the nutrient solutions containing oxidized human wastes for application in bio-technical life support systems. The study shows that the addition of IES to the root-inhabited substrate is favorable for the growth of wheat vegetative organs but causes a decrease in the grain yield. By contrast, the addition of IES to the nutrient solution does not influence the growth of vegetative organs but favors normal development of wheat reproductive organs. Thus, to choose the proper method of adjusting the solution with IES, one should take into account specific parameters of plant growth and development and the possibility of multiple recycling of IES based on the liquid products of mineralization of human wastes.

    The basic objective arising at use of mineralized human solid and liquid wastes serving as the source of mineral elements for plants cultivation in biological-technical life support systems appears to be NaCl presence in them. The given work is aimed at feasibility study of mineralized human metabolites' utilization for nutrient solutions' preparation for their further employment at a long-term cultivation of uneven-aged wheat and Salicornia europaea L. cenosis in a conveyer regime. Human solid and liquid wastes were mineralized by the "wet incineration" method developed by Yu. Kudenko. On their base the solutions were prepared which were used for cultivation of 5-aged wheat conveyer with the time step-interval of 14 days. Wheat was cultivated by hydroponics method on expanded clay aggregate. For partial demineralization of nutrient solution every two weeks after regular wheat harvesting 12 L of solution was withdrawn from the wheat irrigation tank and used for Salicornia europaea cultivation by the water culture method in a conveyer regime. The Salicornia europaea conveyer was represented by 2 ages with the time step-interval of 14 days. Resulting from repeating withdrawal of the solution used for wheat cultivation, sodium concentration in the wheat irrigation solution did not exceed 400 mg/l, and mineral elements contained in the taken solution were used for Salicornia europaea cultivation. The experiment lasted 7 months. Total wheat biomass productivity averaged 30.1 g*m-2*day-1 at harvest index equal to 36.8The work was carried out under support of SB RAS grant 132 and INTAS 05-1000008-8010

In the project on sending of engineers to China in the first term, coal mine engineers of Japan (Taiheiyo Coal Mine, Kushiro Works, Training Center) were sent to the Daitun coal-thermal power plant, Peixuan city, Jiangsu province, in September, 1997 to introduce the production control technology in Japan. They contributed to the heightening of productivity in coal mines in China. Eighteen Chinese participated in the training. Mechanization has been comparatively well in progress, and it was 83% in coal mining and 91% in drilling. The kind of coal is mostly a raw material coal. The stuff members are 30,000, and expert engineers are 4,200. The plant has an output of 130,000 kWh, owns its railroad, is run on the general multiple management, and is largely developing. The project on sending of engineers to China in the last term was carried out in February 1998 for tracing/confirming how the results of the training conducted in September are made the most of and if or not there is something bad and for obtaining the detailed data. A certain degree of promotion and effects were able to be confirmed. A project on training of the head, sub-head, etc. who were invited to Japan to lean production/management control was also carried out in November and December 1997. 1 tab.

    1974-01-01

    Bilateral renal calculi were present in 114 (10.7%) of 1,070 cases of proved urinary calculus admitted to the Urological Department of the General Hospital, Kuala Lumpur, during the period November 1968—May 1973. The management of bilateral renal calculi is discussed with reference to the first 100 cases in this series. The introduction of renography has greatly facilitated the decision as to which kidney should be operated on first. The management of patients with and without uraemia is discussed and the use of the modified V and V—Y incisions for the removal of staghorn calculi is described. Complications and results are briefly reviewed. ImagesFig. 1Fig. 4Fig. 6Fig. 7 PMID:4845653

    OBJECTIVE Bilateral chronic subdural hematoma (bCSDH) is a common neurosurgical condition frequently associated with the need for retreatment. The reason for the high rate of retreatment has not been thoroughly investigated. Thus, the authors focused on determining which independent predictors...... are associated with the retreatment of bCSDH with a focus on surgical laterality. METHODS In a national database of CSDHs (Danish Chronic Subdural Hematoma Study) the authors retrospectively identified all bCSDHs treated in the 4 Danish neurosurgical departments over the 3-year period from 2010 to 2012...... that a separated hematoma density and the absence of postoperative drainage were independent predictors of retreatment. CONCLUSIONS In bCSDHs bilateral surgical intervention significantly lowers the risk of retreatment compared with unilateral intervention and should be considered when choosing a surgical...

    Twenty children with bilateral Wilms' tumor were presented to the Children's Hospital Medical Center and Children's Cancer Research Foundation, Sidney Farber Cancer Institute, and Joint Center for Radiation Therapy (CHMC-CCRF, SFCI, JCRT) from January 1, 1956 to December 31, 1976. Of these 20, 16 had simultaneous and 4 had metachronous disease on presentation. All patients were treated with surgery, radiation and chemotherapy. Of the 16 patients with simultaneous disease, 10 (63%) are alive and free of disease 12+ to 175+ months post diagnosis and treatment, with median follow-up of 121 months. There were no long-term survivors in the metachronous group; all were dead of disease within 21 months from initial presentation of original tumor. With these data we relate prognosis to extent of disease and discuss a general approach to the management of bilateral Wilms' tumor

    Each kidney is supplied by a single renal artery, although renal artery variations are common. Variations of the renal arteryhave become important with the increasing number of renal transplantations. Numerous studies describe variations in renalartery anatomy. Especially the left renal artery is among the most critical arterial variations, because it is the referred side forresecting the donor kidney. During routine dissection in a formalin fixed male cadaver, we have found a bilateral renal...

    Dioctophyma renale is a parasite that frequently occurs in animals but rarely in humans. The present report describes the clinical observations of a D. renale infection in a 51-yr-old woman. Its clinical signs and diagnostic findings were unspecific until giant worms were observed in the urine and histological findings confirmed it was a D. renale infection. She refused treatment and died of bilateral renal function failure. This is the first confirmed report to follow the natural progression of D. renale infection in a human. Here, we discuss a conservative therapeutic approach and features associated with this parasitic infection.

    This report describes a rare case of recurrent bilateral focal myositis and its successful treatment via methotrexate. A 38-year-old man presented myalgia of the right gastrocnemius in May 2005. Magnetic resonance imaging showed very high signal intensity in the right gastrocnemius on short-tau inversion recovery images. A muscle biopsy revealed inflammatory CD4+ cell-dominant myogenic change. Focal myositis was diagnosed. The first steroid treatment was effective. Tapering of prednisolone, however, repeatedly induced myositis relapse, which progressed to multiple muscle lesions of both lower limbs. Initiation of methotrexate finally allowed successful tapering of prednisolone, with no relapse in the past 4 years.

    1993-10-01

    This article reviews 12 patients with bilateral acoustic neuromas. The sex incidence was equal and the mean age at diagnosis was 26.2 years. The family history was positive in nine of the patients. Five patients have had incomplete surgical removal of acoustic neuromas on both sides. Two of them are completely deaf and the other three have severe sensorineural hearing loss in one ear and no hearing in the other ear. In five patients the tumour on one side has been operated on and the other side is being observed with at least short-term preservation of good hearing. The remaining two patients died of intra-cranial complications, one of them post-operatively. Four patients developed facial palsy immediately following surgery and one developed facial weakness 6 months after surgery. Guidelines are discussed for the care of these patients including the timing of surgery and alternative treatment options (observation, radio-surgery and chemotherapy). This is essentially a group of young individuals who have had multiple operations for bilateral acoustic tumours and associated manifestations and for whom the disease and the sequelae of treatment can be tragic.

    2007-01-01

    Full Text Available Breast tuberculosis is a rare form of tuberculosis. Moreover the disease is often overlooked and misdiagnosed as carcinoma or pyogenic abscess. Reports on breast tuberculosis from India have been few; reported incidence of breast tuberculosis amongst the total number of mammary conditions varies between 0.64 and 3.59 per cent. Bilateral involvement is still more uncommon (3%. Most accepted view for spread of infection is centripetal lymphatic spread as axillary node involvement was shown to occur in 50 to 75 per cent of cases of tubercular mastitis. Here we re-port a case of a young female who presented with draining sinuses in the breast and no axillary lymphadenopathy. Fine needle aspiration cytology (FNAC of breast lump showed evidence of granulomatous mastitis. She was given therapeutic trial of four drug antitubercular treatment. Both the lump disappeared and sinus healed after six months of antitubercular treatment. Thus a retrospective diagnosis of tu-bercular mastitis was made.

    Knowledge of the variations of the renal artery has grown in importance with increasing numbers of renal transplants, vascular reconstructions and various surgical and radio logic techniques being performed in recent years. We report the presence of bilateral triple renal arteries, discovered on routine dissection of a male cadaver. On the right side, one additional renal artery originated from the abdominal aorta (distributed to superior pole of the kidney) and one other originated from the right common iliac artery (distributed to lower pole of the kidney). On the left side, both additional renal arteries originated from the abdominal aorta. Our observation has been compared with variations described in the literature and their clinical importance has been emphasized. (author)

    2015-01-01

    Full Text Available Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.

    Full Text Available A case of bilateral persistent hyperplastic primary vitreous (PHPV in a 3-month-old male infant, who had bilateral leukokoria, is presented. The child was referred for imaging with a clinical suspicion of retinoblastoma. Gray-scale ultrasound evaluation revealed an echogenic band in the posterior segment of both globes, extending from the posterior surface of the lens capsule to the optic disc. Doppler examination revealed the presence of arterial flow in the band in both globes. Associated echogenic hemorrhage was also seen, which was confirmed by computed tomography. Most cases of PHPV are sporadic and unilateral, and bilateral PHPV is rare. The imaging features in this case suggest the diagnosis of bilateral PHPV and differentiate it from retinoblastoma. This entity, although infrequent, should be considered in the differential diagnosis while evaluating bilateral leukokoria.

    The objectives were to develop a non-volatile tracer to use in gas exchange experiments in laterally unconfined systems and to study applications of deliberate tracers in limnology and oceanography. Progress was made on both fronts but work on the development of the non-volatile tracer proved to be more difficult and labor intensive that anticipated so no field experiments using non-volatile tracers was performed as yet. In the search for a suitable non-volatile tracer for an ocean scale gas exchange experiment a tracer was discovered which does not have the required sensitivity for a large scale experiment, but is very easy to analyze and will be well suited for smaller experiments such as gas exchange determinations on rivers and streams. Sulfur hexafluoride, SF 6 , was used successfully as a volatile tracer along with tritium as a non-volatile tracer to study gas exchange rates from a primary stream. This is the first gas exchange experiment in which gas exchange rates were determined on a head water stream where significant groundwater input occurs along the reach. In conjunction with SF 6 , Radon-222 measurements were performed on the groundwater and in the stream. The feasibility of using a combination of SF 6 and radon is being studied to determine groundwater inputs and gas exchange of rates in streams with significant groundwater input without using a non-volatile tracer

    Wilms tumor is the most common renal tumor in children Synchronous bilateral Wilms tumor (BWT) accounts for 5% of all patients registered to the National Wilms Tumor Study Group (NWSTG). A 28-year-old female patient was presented to Oncology Institute with right kidney tumor. Her left kidney was resected due to Wilms tumor in the sixth month of her life. Abdominal ultrasound was performed and demonstrated a massive right kidney tumor. Then the abdominal CT was undertaken with the use of 16-slice CT scanner, revealing rotation displacement of the right kidney, with signs of compensative overgrowth and displaced upwards. In the lower and peripheral part of the kidney a nodular mass 7 X 10 X 9 cm in size was visible. The tumor was well-demarcated, showing heterogeneous contrast enhancement, extending from the inferio-lateral renal pole.The tumor was adjacent to iliopsoas muscle and abdominal cavity walls; no infiltration of those structures was noted. Described lesion surrounded inferio-medial part of the kidney, approaching kidney pelvis without infiltrating them. Supero-anterior and medial part of the kidney showed normal structure with correct contrasted urine excretion. Lymph nodes enlargement within periaortal area was not detected. Surgical procedure was performed resulting in excision of the tumor with kidney preservation. Histopathology examination revealed nephroblastoma. The tumor was surrounded by a thin, fibrous capsule. Surrounding parenchyma and far tissue were not involved. The CT examination performed 4 months after nephron sparing surgery revealed: right kidney of 137 X 51 mm in size, normally located, with correct structure and function. Multislice abdominal CT have clearly visualized the tumor of the single kidney, showing precise localization of the mass with relation to the kidney pelvis and vessels, allowing for nephron sparing surgical excision.

    Full Text Available Laryngocele is an air-filled, abnormal dilation of the laryngeal saccule that extends upward within the false vocal fold, in communication with the laryngeal lumen. A case of 43-year-old male with bilateral internal laryngoceles, who has been treated as asthma for 4 years, is presented. The patient had dyspnea, cough, and excessive phlegm for a month and a late onset stridor. Flexible nasopharyngolaryngoscopy showed bilateral cystic enlargements of the false vocal folds and true vocal folds could not be visualized. Laryngeal CT without contrast enhancement showed bilateral internal laryngoceles. Submucosal total excision of bilateral cystic masses including parts of false vocal folds was performed. The symptoms resolved immediately after surgery. Although the incidence of internal laryngocele is rare, it should be remembered in the differential diagnosis of upper airway problems and diagnostic flexible nasopharnygolaryngoscopy is routinely indicated for airway evaluation in at-risk patients.

    Accurate appraisal of the risk of extreme floods has long been of concern to hydrologists and water resources managers in both the United States and China. In order to exchange information, assess current developments, and discuss further needs in extreme flood analysis, the U.S. Geological Survey (USGS) and the Bureau of Hydrology of the Ministry of Water Resources and Electric Power of the People's Republic of China (PRC) held the Bilateral Symposium on the Analysis of Extraordinary Flood Events, October 14-18, 1985, in Nanjing, China. Co-convenors of the symposium were Marshall E. Moss (USGS) and Hua Shiqian (Nanjing Research Institute of Hydrology). Liang Ruiju (East China Technical University of Water Resources) was executive secretary of the organizing committee. Participants included 23 U.S. delegates, 36 Chinese delegates, and five guests from other countries. Of the U.S. delegates, 13 were from federal agencies, seven were from universities, and three were private consultants. The U.S. National Science Foundation gave financial support to the nonfederal U.S. delegates. Major topics covered in the 52 papers presented included detection of historical floods and evaluation of the uncertainties in their peak discharges and times of occurrence,frequency analysis and design flood determination in the presence of extraordinary floods and historic floods, anduse of storm data in determining design storms and design floods, The symposium was followed by a 6-day study tour in central China, during which laboratories, field activities, and offices of various water resources agencies were visited and sites of documented historic floods on the Yangtze River and its tributaries were examined.

    2012-01-01

    Inverted papilloma (IP) is a benign tumor of the nasal cavity and paranasal sinuses that is unilateral in most cases. Bilateral IP, involving both sides of the nasal cavity and sinuses, is extremely rare. This paper describes a large IP that filled in both sides of the nasal cavity and sinuses, mimicking association with malignancy. The tumor was successfully treated by bilateral endoscopic medial maxillectomy (EMM). The patient is without evidence of the disease 24 months after surgery. If preoperative diagnosis does not confirm the association with malignancy in IP, endoscopic sinus surgery (ESS) should be selected, and ESS, including EMM, is a good first choice of the treatment for IP.

    2006-10-01

    Full Text Available Abstract Background The most common causes of hemotympanum are therapeutic nasal packing, epistaxis, blood disorders and blunt trauma to the head. Hemotympanum is characterized as idiopathic, when it is detected in the presence of chronic otitis media. A rare case of spontaneous bilateral hemotympanum in a patient treated with anticoagulants is presented herein. Case presentation A 72-year-old male presented with acute deterioration of hearing. In the patient's medical history aortic valve replacement 1 year before presentation was reported. Since then he had been administered regularly coumarinic anticoagulants, with INR levels maintained between 3.4 and 4.0. Otoscopy revealed the presence of bilateral hemotympanum. The audiogram showed symmetrical moderately severe mixed hearing loss bilaterally, with the conductive component predominating. Tympanograms were flat bilaterally with absent acoustic reflexes. A computerized tomography scan showed the presence of fluid in the mastoid and middle ear bilaterally. Treatment was conservative and consisted of a 10-day course of antibiotics, anticongestants and temporary interruption of the anticoagulant therapy. After 3 weeks, normal tympanic membranes were found and hearing had returned to previous levels. Conclusion Anticoagulant intake should be included in the differential diagnosis of hemotympanum, because its detection and appropriate treatment may lead to resolution of the disorder.

    Acupuncture is an ancient complementary medicine which is currently used worldwide. Many serious adverse events have been reported which include a spectrum of mild-to-fatal complications. However, the level of awareness with regard to complications is still low both to physicians and patients. We report a 63-year-old who presented with acute shortness of breath 2 hours after having had acupuncture. On examination, there was absent breath sound heard on the left lung and slightly reduced breath sound on the right lung. She had type 1 respiratory failure. Urgent chest radiograph confirmed bilateral pneumothorax which was more severe on the left with tension pneumothorax and mediastinal shift. Chest tubes were inserted bilaterally after failed needle aspiration attempts. Subsequently, the pneumothoraces resolved, and she was discharged well. The bilateral pneumothoraces caused by acupuncture were curable but could have been potentially fatal if diagnosis was delayed. This case report adds to the limited current literature on the complications of acupuncture leading to bilateral pneumothoraces. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

    In well over half of the individuals with rare disease who undergo clinical or research next-generation sequencing, the responsible gene cannot be determined. Some reasons for this relatively low yield include unappreciated phenotypic heterogeneity; locus heterogeneity; somatic and germline mosaicism; variants of uncertain functional significance; technically inaccessible areas of the genome; incorrect mode of inheritance investigated; and inadequate communication between clinicians and basic scientists with knowledge of particular genes, proteins, or biological systems. To facilitate such communication and improve the search for patients or model organisms with similar phenotypes and variants in specific candidate genes, we have developed the Matchmaker Exchange (MME). MME was created to establish a federated network connecting databases of genomic and phenotypic data using a common application programming interface (API). To date, seven databases can exchange data using the API (GeneMatcher, PhenomeCentral, DECIPHER, MyGene2, matchbox, Australian Genomics Health Alliance Patient Archive, and Monarch Initiative; the latter included for model organism matching). This article guides usage of the MME for rare disease gene discovery. © 2017 by John Wiley & Sons, Inc. Copyright © 2017 John Wiley and Sons, Inc.

    1993-11-01

    In an evaluation of the Department of Energy (DOE) Occupational Safety and Health programs for government-owned contractor-operated (GOCO) activities, the Department of Labor`s Occupational Safety and Health Administration (OSHA) recommended a technical information exchange program. The intent was to share written safety and health programs, plans, training manuals, and materials within the entire DOE community. The OSH Technical Reference (OTR) helps support the secretary`s response to the OSHA finding by providing a one-stop resource and referral for technical information that relates to safe operations and practice. It also serves as a technical information exchange tool to reference DOE-wide materials pertinent to specific safety topics and, with some modification, as a training aid. The OTR bridges the gap between general safety documents and very specific requirements documents. It is tailored to the DOE community and incorporates DOE field experience.

    Full Text Available Inverted papilloma (IP is a benign tumor of the nasal cavity and paranasal sinuses that is unilateral in most cases. Bilateral IP, involving both sides of the nasal cavity and sinuses, is extremely rare. This paper describes a large IP that filled in both sides of the nasal cavity and sinuses, mimicking association with malignancy. The tumor was successfully treated by bilateral endoscopic medial maxillectomy (EMM. The patient is without evidence of the disease 24 months after surgery. If preoperative diagnosis does not confirm the association with malignancy in IP, endoscopic sinus surgery (ESS should be selected, and ESS, including EMM, is a good first choice of the treatment for IP.

    Full Text Available OBJECTIVE: To evaluate the efficacy and safety of bilateral pallidotomies in five patients with generalized dystonia. BACKGROUND: Generalized dystonias are frequently a therapeutic challenge, with poor responses to pharmacological treatment. GPi (globus pallidus internus pallidotomies for Parkinson's disease ameliorate all kinds of dyskinesias/dystonia, and recent studies reported a marked improvement of refractory dystonias with this procedure. METHODS: Five patients with generalized dystonias refractory to medical treatment were selected; one posttraumatic and four idiopathic. The decision to perform bilateral procedures was based on the predominant axial involvement in these patients. Dystonia severity was assessed with the Burke-Fahn-Marsden Dystonia Scale (BFM. Simultaneous procedures were performed in all but one patient, who had a staged procedure. They were reevaluated with the same scale (BFM by an unblinded rater at 1, 2, 3, 30, 60, 90, 120 and 180 days post-operatively. RESULTS: The four patients with idiopathic dystonia showed a progressive improvement up to three months; the patient with posttraumatic dystonia relapsed at three months. One patient had a marked improvement, being able to discontinue all the medications. A mean decrease in the BFM scores of 52,58% was noted. One patient had a trans-operative motor seizure followed by a transient hemiparesis secondary to rack hemorrhage; other was lethargic up to three days after the procedure. CONCLUSIONS: Our results show that bilateral GPi pallidotomies may be a safe and effective approach to medically refractory generalized dystonias; it can also be speculated that the posttraumatic subgroup may not benefit with this procedure.As distonias generalizadas são freqüentemente um desafio terapêutico, com pobres respostas aos tratamentos farmacológicos.

Analysing quarterly data for the 2004-2015 period, we find the presence of a J-curve effect in the cases of Germany, Austria and Croatia. In contrast, we find that the Marshall-Lerner conditions are fulfilled in the case of bilateral trade with Austria. Finally, in our estimates the elasticity to income has a greater impact on the export and import demand functions than the elasticity to the exchange rate. JEL Classification: F14, F31, F32

  15. Bilateral Vocal Fold Medialization: A Treatment for Abductor Spasmodic Dysphonia.

    Dewan, Karuna; Berke, Gerald S

    2017-11-10

    Abductor spasmodic dysphonia, a difficult-to-treat laryngologic condition, is characterized by spasms causing the vocal folds to remain abducted despite efforts to adduct them during phonation. Traditional treatment for abductor spasmodic dysphonia-botulinum toxin injection into the posterior cricoarytenoid muscle-can be both technically challenging and uncomfortable. Due to the difficulty of needle placement, it is often unsuccessful. The purpose of this investigation is to present a previously undescribed treatment for abductor spasmodic dysphonia-bilateral vocal fold medialization. A retrospective case review of all cases of abductor spasmodic dysphonia treated in a tertiary care laryngology practice with bilateral vocal fold medialization over a 10-year period was performed. The Voice Handicap Index and the Voice-Related Quality of Life surveys were utilized to assess patient satisfaction with voice outcome. Six patients with abductor spasmodic dysphonia treated with bilateral vocal fold medialization were identified. Disease severity ranged from mild to severe. All six patients reported statistically significant improvement in nearly all Voice Handicap Index and Voice-Related Quality of Life parameters. They reported fewer voice breaks and greater ease of communication. Results were noted immediately and symptoms continue to be well controlled for many years following medialization. Bilateral vocal fold medialization is a safe and effective treatment for abductor spasmodic dysphonia. It is performed under local anesthesia and provides phonation improvement in the short and long term. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    Love, Brooke A.; Olson, M. Brady; Wuori, Tristen

    2017-05-01

    As research into the biotic effects of ocean acidification has increased, the methods for simulating these environmental changes in the laboratory have multiplied. Here we describe the atmospheric carbon control simulator (ACCS) for the maintenance of plankton under controlled pCO2 conditions, designed for species sensitive to the physical disturbance introduced by the bubbling of cultures and for studies involving trophic interaction. The system consists of gas mixing and equilibration components coupled with large-volume atmospheric simulation chambers. These chambers allow gas exchange to counteract the changes in carbonate chemistry induced by the metabolic activity of the organisms. The system is relatively low cost, very flexible, and when used in conjunction with semi-continuous culture methods, it increases the density of organisms kept under realistic conditions, increases the allowable time interval between dilutions, and/or decreases the metabolically driven change in carbonate chemistry during these intervals. It accommodates a large number of culture vessels, which facilitate multi-trophic level studies and allow the tracking of variable responses within and across plankton populations to ocean acidification. It also includes components that increase the reliability of gas mixing systems using mass flow controllers.

    Rothberg, G.M.

    1984-01-01

    Progress has been made toward developing Spin Polarized EXAFS (SPEXAFS) as a technique for studying magnetism in solids. The first observations have been made of EXAFS by means of photoemission with sufficient data to permit a traditional Fourier-transform analysis of atomic structure. Some of the advantages of photoelectron detection of EXAFS are: (1) vuv light may be used thereby extending greatly the useable range of photon energies; (2) the number of elements that may be studied for surface EXAFS is increased; (3) the possibility exists for measurements that cannot be done in other ways. In addition to its intrinsic interest, this result is crucial to the study of the spin dependence of EXAFS. These measurements were carried out on the vuv storage ring at the National Synchrotron Light Source. Data obtained on the spin dependence of EXAFS in MnF 2 at room temperature tentatively show dependence of the Mn absorber atom phase shift on the exchange interaction within the absorber atom. This effect has not been discussed theoretically. Preliminary observations have been made of the Fano resonance in Mn 3d photoemission at the 3p to 3d threshold

    With the emphasis on bilateral hearing nowadays, bilateral cochlear implantation has been tried out for bilateral aural rehabilitation. Bilateral sensorineural hearing loss caused by head trauma can get help from cochlear implantation. We present the case of a 44-year-old man with bilateral otic capsule violating temporal bone fractures due to head trauma. The patient demonstrated much improved audiometric and psychoacoustic performance after bilateral cochlear implantation. We believe bilateral cochlear implantation in such patient can be a very effective tool for rehabilitation. Copyright © 2011 Elsevier Inc. All rights reserved.

    This paper proposes a cascade control scheme for delayed bilateral teleoperation of a quadcopter. The strategy transforms a 6D real quadcopter to an easy-to-teleoperate 3D virtual quadcopter. The scheme is formed by a P+d plus PID controller for each dof. The analysis based on Lyapunov theory gets as result the way to set the control parameters depending on the magnitude of the asymmetric time delays (forward and backward delays). This technic aims to reach stability, simplicity and good performance in practice. Besides, experimental tests about delayed bilateral teleoperation of a quadcopter including the proposed control scheme are shown in order to evaluate the system performance. Copyright © 2017 ISA.

    Concerning a hydraulic bilateral construction robot, its system constitution, structures and functions of important components, and the results of some tests are explained, and the researches conducted at Gifu University are described. The construction robot in this report is a servo controlled system of a version developed from the mini-shovel now available in the market. It is equipped, in addition to an electrohydraulic servo control system, with various sensors for detecting the robot attitude, vibration, and load state, and with a camera for visualizing the surrounding landscape. It is also provided with a bilateral joy stick which is a remote control actuator capable of working sensation feedback and with a rocking unit that creates robot movements of rolling, pitching, and heaving. The construction robot discussed here, with output increased and response faster thanks to the employment of a hydraulic driving system for the aim of building a robot system superior in performance to the conventional model designed primarily for heavy duty, proves after tests to be a highly sophisticated remotely controlled robot control system.

    Full Text Available Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it′s management both at the time of cleft lip repair

    2013-01-01

    In Next Generation Microchannel Heat Exchangers, the authors’ focus on the new generation highly efficient heat exchangers and presentation of novel data and technical expertise not available in the open literature.  Next generation micro channels offer record high heat transfer coefficients with pressure drops much less than conventional micro channel heat exchangers. These inherent features promise fast penetration into many mew markets, including high heat flux cooling of electronics, waste heat recovery and energy efficiency enhancement applications, alternative energy systems, as well as applications in mass exchangers and chemical reactor systems. The combination of up to the minute research findings and technical know-how make this book very timely as the search for high performance heat and mass exchangers that can cut costs in materials consumption intensifies.

    2013-09-01

    Controversy exists on optimal endoscopic management for palliation of malignant hilar obstruction, with advocates for metal "side-by-side" (SBS) and "stent-in-stent" (SIS) techniques. We sought to evaluate the technical feasibility, efficacy, and outcomes of bilateral biliary self-expanding metal stents (SEMS) for treatment of malignant hilar obstruction using a stent with a 6Fr delivery system. This was a single-center, retrospective review of all patients who underwent bilateral placement of Zilver® biliary SEMS for malignant hilar obstruction from January 2010 to August 2012. Patients underwent endoscopic retrograde cholangiopancreatography with placement of stents using either the SIS or SBS stent techniques. Twenty-four patients (19 men, mean age 63 years) underwent bilateral stenting for malignant hilar obstruction during the study period. Seventeen and seven patients underwent the SBS and SIS technique, respectively. Cholangiocarcinoma (n=14) was the most common cause of hilar obstruction. Initial technical success was achieved in 24/24 (100%) of patients; however, 12 (50%) patients required re-intervention during the study period (median 98 days). Comparison of the SBS and SIS groups revealed no statistical difference with respect to need for re-intervention (P=0.31), successful re-intervention (P=0.60), or procedural length (P=0.89). Use of bilateral Zilver® SEMS in either the SBS or SIS configuration is safe, technically feasible, and effective for drainage of malignant hilar obstruction; however, duration of stent patency and procedure-free survival remain variable.

  12. Bilateral absence of musculocutaneous nerve

    Full Text Available Brachial plexus is an important group of spinal nerve plexus that supplies the muscles of the upper limb via the ventral rami of the Cervical 5 - Thoracic 1 fibers of the spinal nerves. It is not uncommon to notice the variations during cadaveric dissections in many regions of the body, at different levels, such as, roots, trunks, division, cords, communications, and branches as reported in the literature. Although the nerve supply of the body musculature takes place in the fetal life itself, its course, branching pattern, innervations, and communication can show variable patterns as the fetal development progresses. One such anomaly was noticed during our routine cadaveric dissection in the Department of Anatomy, Jawaharlal Nehru Medical College, Belgaum, showing bilateral absence of the musculocutaneous nerve, which obviously drew the attention of the students of medicine, physiotherapy, and learning clinicians as well.

  13. Bilateral supernumerary primary maxillary canines

    2018-01-01

    Full Text Available Supernumerary teeth are more common in the permanent than in primary dentition. In the primary dentition, the anomaly is most frequently observed in the maxillary lateral incisor region, followed by the maxillary midline where they are termed as mesiodens. Supernumerary teeth in the primary canine region are rare. This paper describes a rare case of nonsyndromic supernumerary primary maxillary canine distributed bilaterally in a 4-year-old boy. Both the supernumeraries resembled size and shape of normal primary canine. The right supplemental canine is high labially placed, whereas the left one is seen normally aligned in the dental arch distal to lateral incisor. One of the most significant sequelae of primary supernumerary teeth is their duplication in the permanent series. Radiographic examination of supernumerary primary canine did not indicate any such anomaly in the permanent dentition. The patient was kept under observation.

    Endoscopic bilateral drainage for inoperable malignant hilar biliary strictures (HBS) using metal stents is considered to be technically difficult. Furthermore, endoscopic revision of bilateral stenting after occlusion can be challenging. This study was performed to evaluate the long-term efficacy of endoscopic bilateral stent-in-stent placement of cross-wired metallic stents in high-grade malignant HBS and planned endoscopic bilateral revision. A total of 84 patients with inoperable high-grade malignant HBS were enrolled from three academic tertiary referral centers. Two cross-wired metal stents were inserted using a bilateral stent-in-stent placement method. Bilateral endoscopic revision was also performed during follow-up using either identical metal stents or plastic stents. The main outcome measurements were technical and functional success, complications, stent patency, and endoscopic revision efficacy. The technical and clinical success rates of endoscopic bilateral stent-in-stent placement of cross-wired metallic stents were 95.2% (80/84) and 92.9% (78/84), respectively. Median patency (range) and survival were 238 days (10-429) and 256 days (10-1130), respectively. Obstruction of primary bilateral stents occurred in 30.8% (24/78) of patients with functionally successful stent placement. The technical and clinical success rates of planned bilateral endoscopic revision for occluded stents were 83.3% (20/24) and 79.2% (19/24), respectively. For revision, bilateral metallic stents were placed in 11 patients (55.0%); the remaining patients received plastic stents. Palliative endoscopic bilateral stent-in-stent placement of cross-wired metallic stents was effective in patients with inoperable HBS. Revision endoscopic bilateral stenting may be feasible and successful in cases where the primary deployed metal stents are occluded. © Georg Thieme Verlag KG Stuttgart · New York.

    In the execution of its charter, the SRS Ion Exchange Technology Assessment Team has determined that ion exchange (IX) technology has evolved to the point where it should now be considered as a viable alternative to the SRS reference ITP/LW/PH process. The ion exchange media available today offer the ability to design ion exchange processing systems tailored to the unique physical and chemical properties of SRS soluble HLW's. The technical assessment of IX technology and its applicability to the processing of SRS soluble HLW has demonstrated that IX is unquestionably a viable technology. A task team was chartered to evaluate the technology of ion exchange and its potential for replacing the present In-Tank Precipitation and proposed Late Wash processes to remove Cs, Sr, and Pu from soluble salt solutions at the Savannah River Site. This report documents the ion exchange technology assessment and conclusions of the task team

    In preparation for future nuclear arms reduction treaties, including any potential successor treaties to START I and II, the authors have been examining possible methods for bilateral warhead dismantlement verification. Warhead dismantlement verification raises significant challenges in the political, legal, and technical arenas. This discussion will focus on the technical issues raised by warhead arms controls. Technical complications arise from several sources. These will be discussed under the headings of warhead authentication, chain-of-custody, dismantlement verification, non-nuclear component tracking, component monitoring, and irreversibility. The authors will discuss possible technical options to address these challenges as applied to a generic dismantlement and disposition process, in the process identifying limitations and vulnerabilities. They expect that these considerations will play a large role in any future arms reduction effort and, therefore, should be addressed in a timely fashion

    The aim of the study was to investigate whether children with bilateral conductive hearing loss benefit from their second device (i.e., the bilateral bone conduction device [BCD]). Speech recognition in noise was assessed in 10 children fitted with bilateral BCDs during childhood. Speech recognition was measured in 2 conditions with both BCDs active. Spatial resolution was tested with the Minimum Audible Angle test in the bilateral and monaural listening conditions. Children demonstrated an improvement in speech recognition when speech was presented from the front and noise was presented from the right-hand side as compared with both speech and noise being presented from the front. The minimum audible angle decreased from 57° in the best monaural condition to 13° in the bilateral condition. The audiological outcomes demonstrate the advantage of bilateral BCD fitting in children with bilateral conductive hearing loss.

    The nearly completed Defense Waste Processing Facility (DWPF) is a Department of Energy (DOE) facility at the Savannah River Site that is designed to immobilize defense high level radioactive waste (HLW) by vitrification in borosilicate glass and containment in stainless steel canisters suitable for storage in the future DOE HLW repository. The DWPF is expected to start cold operation later this year (1990), and will be the first full scale vitrification facility operating in the United States, and the largest in the world. The DOE has been coordinating technology transfer and exchange on issues relating to HLW treatment and disposal through bi-lateral agreements with several nations. For the nearly fifteen years of the vitrification program at Savannah River Laboratory, over two hundred exchanges have been conducted with a dozen international agencies involving about five-hundred foreign national specialists. These international exchanges have been beneficial to the DOE's waste management efforts through confirmation of the choice of the waste form, enhanced understanding of melter operating phenomena, support for paths forward in political/regulatory arenas, confirmation of costs for waste form compliance programs, and establishing the need for enhancements of melter facility designs. This paper will compare designs and schedules of the international vitrification programs, and will discuss technical areas where the exchanges have provided data that have confirmed and aided US research and development efforts, impacted the design of the DWPF and guided the planning for regulatory interaction and product acceptance

  15. Acute Bilateral Superior Branch Vestibular Neuropathy

    2018-05-01

    Full Text Available The rapid onset of a bilateral vestibular hypofunction (BVH is often attributed to vestibular ototoxicity. However, without any prior exposure to ototoxins, the idiopathic form of BVH is most common. Although sequential bilateral vestibular neuritis (VN is described as a cause of BVH, clinical evidence for simultaneous and acute onset bilateral VN is unknown. We describe a patient with an acute onset of severe gait ataxia and oscillopsia with features compatible with acute BVH putatively due to a bilateral VN, which we serially evaluated with clinical and laboratory vestibular function testing over the course of 1 year. Initially, bilateral superior and horizontal semicircular canals and bilateral utricles were impaired, consistent with damage to both superior branches of each vestibular nerve. Hearing was spared. Only modest results were obtained following 6 months of vestibular rehabilitation. At a 1-year follow-up, only the utricular function of one side recovered. This case is the first evidence supporting an acute presentation of bilateral VN as a cause for BVH, which would not have been observed without critical assessment of each of the 10 vestibular end organs.

    We reported a case of cryptococcal meningitis presenting with bilateral optic neuropathy in an immunocompetent patient. A 64-year-old Malay gentleman with no medical comorbidities presented with acute bilateral blurring of vision for a week, which was associated with generalised throbbing headache and low grade fever. He also had som-nolence and altered consciousness. Visual acuity in both eyes was no perception of light with poor pupillary reflexes. Extraocular muscle movements were normal. Anterior segments were unremarkable bilaterally. Fundoscopy revealed bilateral optic disc swelling. CT scan of the brain showed multifocal infarct, but no meningeal enhancement or mass. Cerebrospinal fluid opening pressure was normal, while its culture grew Cryptococcus neoformans. A diagnosis of cryptococcal meningitis with bilateral optic neuropathy was made. Patient was treated with a six-week course of intravenous flu-conazole and started concomitantly on a fortnight's course of intravenous amphotericin B. After that, his general condition improved, but there was still no improvement in his visual acuity. On reviewing at two months post-initiation of treatment, fundi showed bilateral optic atrophy. Bilateral optic neuropathy secondary to cryptococcal meningitis was rare. The prognosis was guarded due to the sequelae of optic atrophy. Anti-fungal medication alone may not be sufficient to manage this condition. However, evidence for other treatment modalities is still lacking and further clinical studies are required.

    Juvenile nasopharyngeal angiofibroma is a benign, vascular tumour that primarily occurs in adolescent males. Despite its benign nature, aggressive growth patterns can cause potential life-threatening complications. Juvenile nasopharyngeal angiofibroma is normally unilateral, originating from the sphenopalatine artery, but bilateral symptoms can occur if a large tumour extends to the contralateral side of the nasopharynx. This paper presents the first reported case of true bilateral extensive juvenile nasopharyngeal angiofibroma involving clinically challenging pre-surgical planning and surgical strategy. A 21-year-old male presented with increasing bilateral nasal obstruction and discharge. Examination revealed tumours bilaterally and imaging demonstrated non-contiguous tumours. Pre-operative angiography showed strictly ipsilateral vascular supplies requiring bilateral embolisation. Radical removal performed as one-step, computer-assisted functional endoscopic sinus surgery was performed. The follow-up period was uncomplicated. This case illustrates the importance of suspecting bilateral juvenile nasopharyngeal angiofibroma in patients presenting with bilateral symptoms. Our management, including successful pre-operative planning, enabled one-step total removal of both tumours and rapid patient recovery.

    Fibromuscular dysplasia (FMD) describes a group of conditions which cause nonatheromatous arterial stenoses, most commonly of the renal and carotid arteries, typically in young women. We report a rare case of bilateral segmental renal infarction secondary to FMD in a young male patient. His initial presentation with loin pain and pyrexia resulted in a delay in the definitive diagnosis of FMD. He was successfully treated with bilateral balloon angioplasty. The delayed diagnosis in this patient until the condition had progressed to bilateral renal infarcts highlights the need for prompt investigation and diagnosis of suspected cases of FMD.

    To study the development of the bilateral benefit in children using bilateral cochlear implants by measurements of speech recognition and sound localization. Bilateral and unilateral speech recognition in quiet, in multi-source noise, and horizontal sound localization was measured at three occasions during a two-year period, without controlling for age or implant experience. Longitudinal and cross-sectional analyses were performed. Results were compared to cross-sectional data from children with normal hearing. Seventy-eight children aged 5.1-11.9 years, with a mean bilateral cochlear implant experience of 3.3 years and a mean age of 7.8 years, at inclusion in the study. Thirty children with normal hearing aged 4.8-9.0 years provided normative data. For children with cochlear implants, bilateral and unilateral speech recognition in quiet was comparable whereas a bilateral benefit for speech recognition in noise and sound localization was found at all three test occasions. Absolute performance was lower than in children with normal hearing. Early bilateral implantation facilitated sound localization. A bilateral benefit for speech recognition in noise and sound localization continues to exist over time for children with bilateral cochlear implants, but no relative improvement is found after three years of bilateral cochlear implant experience.

    Full Text Available Bilateral tubal pregnancy is very rare and occurs in only 1 out of every 200,000 spontaneous pregnancies. In this case, a 29-year-old woman with a history of primary infertility underwent treatment with human menopausal gonadotropin (hMG-human chorionic gonadotropin (hCG, and became pregnant. A gestational sac (GS was not detected in the uterus and transvaginal ultrasonography (USG revealed GS with fetal heartbeat in the left adnexa at 7 weeks and 6 days of gestation. The patient underwent laparoscopic surgery and ultimately, bilateral tubal pregnancy was diagnosed. Consequently, bilateral fallopian tube resection was performed. Afterwards, she conceived by assisted reproductive technology (ART and delivered vaginally. This case suggests that even if a GS is found in one fallopian tube by USG, it is important to evaluate the other fallopian tube carefully.

    Nasolabial cysts are rare, nonodontogenic, soft-tissue, developmental cysts occurring inferior to the nasal alar region. They are thought to arise from remnants of the nasolacrimal ducts and they are frequently asymptomatic. We report a rare case of bilateral nasolabial cysts accompanied by bilateral chronic dacryocystitis. A 48-year-old woman suffering from bilateral chronic dacryocystitis was referred to our department for endonasal dacryocystorhinostomy. She had undergone external dacryocystorhinostomy on the left side a few years earlier. Physical examination and computed tomography scan revealed nasolabial cysts bilaterally inferior to the nasal alar region. The cysts were removed via a sublabial approach and endoscopic dacryocystorhinostomy was performed on the right side. Ten months after surgery, the patient was asymptomatic. There may be a correlation, due to embryological reasons, between the presence of nasolabial cysts and the presence of chronic dacryocystitis. Both can be corrected surgically, under the same anaesthesia, without visible scar formation.

The decrease and even the elimination of tariff and non-tariff barriers in the world trade are among the main objectives of the EU strategy for international trade. At the moment, the elusive outcome of the WTO Doha Round has led to the proliferation of bilateral trade agreements worldwide. Although the EU remains committed to further development of the multilateral trading system, however, the EU still has appealed also to the development of bilateral trade relations. The aim of this paper is to illustrate the current bilateral dimension of the common commercial policy of the EU. In conclusion, to describe this bilateral approach of the EU we are using one word, namely “diversity”.

  4. FLOWING BILATERAL FILTER: DEFINITION AND IMPLEMENTATIONS

    Full Text Available The bilateral filter plays a key role in image processing applications due to its intuitive parameterization and its high quality filter result, smoothing homogeneous regions while preserving the edges of the objects. Considering the image as a topological relief, seeing pixel intensities as peaks and valleys, we introduce a way to control the tonal weighting coefficients, the flowing bilateral filter, reducing "halo" artifacts typically produced by the regular bilateral filter around a large peak surrounded by two valleys of lower values. In this paper we propose to investigate exact and approximated versions of CPU and parallel GPU (Graphical Processing Unit based implementations of the regular and flowing bilateral filter using the NVidia CUDA API. Fast implementations of these filters are important for the processing of large 3D volumes up to several GB acquired by x-ray or electron tomography.

    Full Text Available We present a case study of a person (63 year-old man, who has been using statins for 18 years, with rhabdomyolysis of the bilateral adductor muscles associated with strenuous and prolonged eccentric exercises (hiking in a hot environment. Clinical examination showed predominantly on the right side muscle swelling and palpational pain of the bilateral adductor muscle groups and bilateral tibial edema. His serum creatine kinase (CK level was 12218 IU/L. T2-weighted magnetic resonance (MR images showed a high signal intensity in the bilateral adductor muscles of the hip. The patient did not develop complications and returned to his previous performance level in 30 days following adequate hydration and resting of the affected muscles. Strenuous eccentric exercise should be avoided during the course of statin use and clinicians should be aware of present observations when considering the significance of acute CK elevations in patients on statin treatment

    Full Text Available Spontaneous bilateral ectopic gestation is very rare. The authors report a case diagnosed and taken care of at Yalgado Ouedraogo Teaching Hospital, Ouagadougou. It was a 30-year-old patient with no known pathological history. She had presented at the obstetric emergencies with a state of hypovolemic shock by haemoperitoneum with digestive disorders, pelvic pain, vaginal bleeding, and a mention of delayed menstruation. The ultrasound coupled with the urinary immunological pregnancy test confirmed the diagnosis of ruptured ectopic pregnancy and a bilateral form was suspected. A laparotomy in emergency confirmed the diagnosis of bilateral ectopic gestation with a right ampullary unruptured pregnancy and a left isthmic ruptured gestation. A bilateral salpingectomy was performed and counseling was made for the use of medical help of procreation in case of future need of pregnancy.

    A case of bilateral calcaneal epiphysiolysis in a six-month-old female Dobermann Pinscher is described in this report. The absence of a traumatic event and the clinical, radiographic and histopathological abnormalities led us to the diagnosis of simultaneous bilateral epiphysiolysis of the calcaneus. A tension band and a type II transarticular external fixator were placed. The clinical signs were resolved only temporarily because of the gravity of the bone changes.

    Renal cell carcinoma (RCC) is a malignant lethal tumour with high potential of metastasis. However, metastasis from RCC to the skin is much less common. It is virtually a sign of poor prognosis. We represent a 42 years old man with bilateral RCC of clear cell type followed by metastasis to the scalp one month later. In this case the relatively young age of the patient, bilaterality of RCC and occurance of skin metastasis in the absence of recurrent kidney tumour are interesting.

    2018-01-01

    Full Text Available Bilateral uveal effusion syndrome associated with bilateral acute retinal necrosis is a diagnostic and therapeutic challenge. A 52 year old man presented with bilateral angle closure with choroidal detachment. With restricted fundus view, parenteral steroid was started. During close follow up bilateral discrete areas of peripheral retinitis were noted. Parenteral steroids were promptly stopped and parenteral antivirals with oral steroids were continued. It showed healing response with nil recurrences till last follow up. Aggressive treatment of bilateral uveal effusion with parenteral steroids can cause progression of bilateral acute retinal necrosis leading to phthisis bulbi. However early diagnosis, prompt intervention and close follow up are the key elements to therapeutic success even during diagnostic surprises and avoid costly mistakes.

    To present a case of a patient with simultaneous bilateral retinal detachments treated successfully with bilateral pneumatic retinopexy. Case report. This is a case of an otherwise healthy 49-year-old woman with no remarkable ocular history that presented with simultaneous phakic superior bilateral rhegmatogenous retinal detachments. Treatment on the day of presentation included laser retinopexy of the inferior lattice degeneration in the left eye and bilateral intravitreal injection of 0.4 cc of 100% C3F8 gas preceded by topical anesthesia. After 48 hours, both retinas were completely reattached, and bilateral laser retinopexy was performed to the superior tears. After a review of the literature, the authors could find only two reported cases of simultaneous bilateral retinal detachments treated successfully with pneumatic retinopexy. This is not only a cost-effective procedure but also allows treatment when there is no immediate operating room availability or a when a quick referral for surgery is not possible.

    Fouling can occur in many heat exchanger applications in a way that impedes heat transfer and fluid flow and reduces the heat transfer or performance capability of the heat exchanger. Fouling may be significant for heat exchanger surfaces and flow paths in contact with plant service water. This report presents guidelines for performance monitoring of heat exchangers subject to fouling. Guidelines include selection of heat exchangers to monitor based on system function, safety function and system configuration. Five monitoring methods are discussed: the heat transfer, temperature monitoring, temperature effectiveness, delta P and periodic maintenance methods. Guidelines are included for selecting the appropriate monitoring methods and for implementing the selected methods. The report also includes a bibliography, example calculations, and technical notes applicable to the heat transfer method

    Full Text Available We report the clinical findings of a patient with severe bilateral keratectasia 34 years after a penetrating keratoplasty (PK in both eyes. An otherwise healthy 67-year-old man complained of deterioration of the eyesight in both eyes over the last 6 months. The patient was diagnosed with bilateral keratoconus at the age of 32 years, and he underwent a bilateral PK. At presentation, visual acuity was 20/200 in the right eye and light perception in the left eye. A Pentacam pachymetric map revealed a central pachymetry of 720 µm in the right eye and of 710 µm in the left eye, as well as an average paracentral pachymetry of 436 and 270 µm in the 9-mm zone in the right and the left eye, respectively. Corneal topography revealed bilateral irregular and asymmetric bowing with generalized steepening and high corneal power. We describe a case of bilateral keratectasia 34 years after PK in a patient who was originally diagnosed with bilateral keratoconus.

    We report on a patient with a rare case of bilateral tension pneumothorax that occurred after acupuncture. A 69-year-old large-bodied man, who otherwise had no risk factors for spontaneous pneumothorax, presented with chest pressure, cold sweats and shortness of breath. Immediately after bilateral pneumothorax had been identified on a chest radiograph in the emergency room, his blood pressure and percutaneous oxygen saturation suddenly decreased to 78 mm Hg and 86%, respectively. We confirmed deterioration in his cardiopulmonary status and diagnosed bilateral tension pneumothorax. We punctured his chest bilaterally and inserted chest tubes for drainage. His vital signs promptly recovered. After the bilateral puncture and drainage, we learnt that he had been treated with acupuncture on his upper back. We finally diagnosed a bilateral tension pneumothorax based on the symptoms that appeared 8 h after the acupuncture. Because the patient had no risk factors for spontaneous pneumothorax, no alternative diagnosis was proposed. We recommend that patients receiving acupuncture around the chest wall must be adequately informed of the possibility of complications and expected symptoms, as a definitive diagnosis can be difficult without complete information.

  19. MODERN VIEWS ON BILATERAL BREAST CANCER

    Full Text Available Presented modern literature data on the features of the pathogenesis, course, clinical and morphological expression and tumor characteristics, parameters and nodal metastasis of hematogenous bilateral breast cancer. Highlight the results of domestic and foreign studies in recent years to determine the prognostic factors and recurrence of synchronous and metachronous bilateral breast cancer. It was revealed that the frequency of bilateral breast tumor lesions varies widely, ranging from 0.1 to 20%, with metachronous tumors recorded significantly higher (69.6% than the synchronous (22.7%. The probability of occurrence of metachronous breast cancer is higher in women with a family history, as well as if they have a gene mutation BRCA-1. Found that the most common histological type of breast tumor with bilateral lesions is invasive ductal. However, the incidence of invasive lobular cancer and non-invasive lobular cancer is slightly higher among synchronous bilateral cancer compared with unilateral disease. Studies have shown that in a double-sided synchronous breast cancer tumor, as a rule, has a lower degree of differentiation, and the higher the expression level of estrogen receptors and progesterone receptors. Relevance of the issue because the identification of patterns in the study of lymphatic and hematogenous features bilateral metastasis of mammary tumors provides a basis for speculation about the differences in the progression of neoplastic disease in these groups and is a cause for further detailed research in this area to identify and evaluate the prognosis and also the choice of tactics of such patients.

  2. Heat exchanger

    International Nuclear Information System (INIS)

    Leigh, D.G.

    1976-01-01

    The arrangement described relates particularly to heat exchangers for use in fast reactor power plants, in which heat is extracted from the reactor core by primary liquid metal coolant and is then transferred to secondary liquid metal coolant by means of intermediate heat exchangers. One of the main requirements of such a system, if used in a pool type fast reactor, is that the pressure drop on the primary coolant side must be kept to a minimum consistent with the maintenance of a limited dynamic head in the pool vessel. The intermediate heat exchanger must also be compact enough to be accommodated in the reactor vessel, and the heat exchanger tubes must be available for inspection and the detection and plugging of leaks. If, however, the heat exchanger is located outside the reactor vessel, as in the case of a loop system reactor, a higher pressure drop on the primary coolant side is acceptable, and space restriction is less severe. An object of the arrangement described is to provide a method of heat exchange and a heat exchanger to meet these problems. A further object is to provide a method that ensures that excessive temperature variations are not imposed on welded tube joints by sudden changes in the primary coolant flow path. Full constructional details are given. (U.K.)

    In Brazil electricity is traded through three segments: the spot market that balances offer and demand, with prices calculated by a cost-based computational model; the regulated market , where prices are settled in public auctions, and the free market for bilateral contracts. As spot and regulated market prices are public information, a seller is able to calculate his opportunity price to trade a bilateral contract in the free market by using the non-arbitrage principle. Thus, the seller searches the price of a bilateral contract in the free market that balances his/her revenues with the value expected in case it were negotiated in the regulated and the spot market. Besides the expected revenue, the seller may also consider the CVaR to measure the risk of her/his bilateral contract in the free market. So this paper develops a binomial lattice approach to price bilateral contracts in the free market, considering the seller's opportunity of negotiations in both regulated and spot markets, and measuring the contract risk directly.

    Only a few reports have discussed the detailed clinical symptoms and pathogenesis of bilateral thalamic infarction. The thalamus is composed of different functional nuclei and supplied by vessels containing several variations from the main arteries, leading to difficulty in the precise evaluation of bilateral thalamic infarction. In the present study, we assessed the prognosis of bilateral thalamic infarction based on the distribution of stroke lesions. From among the consecutive ischemic stroke patients admitted to hospital between April 2001 and March 2005, cases of acute bilateral thalamic infarction were selected for this study (n=9; 65.1±13.6 y.o.). The stroke lesions and vascular abnormalities were investigated by magnetic resonance imaging and magnetic resonance angiography on admission. Outcome was evaluated from the modified Rankin scale (mRS) at discharge. Good outcome patients (mRS 0-2; n=5) showed memory disturbance, cognitive impairment and hypersomnia. On the other hand, quadriplegia, oculomotor disturbance and bulbar palsy were observed in the poor outcome patients (mRS≥4; n=4). The critical features of a poor outcome were the age at onset (72.0±15.3 vs. 58.2±11.9 y.o.), inclusion of brainstem lesions and total occlusion of the basilar artery. In conclusion, older age at onset and/or basilar artery occlusion may be critical factors for predicting a poor outcome in bilateral thalamic infarction cases. (author)

  15. Noise reduction with complex bilateral filter.

    Science.gov (United States)

    Matsumoto, Mitsuharu

    2017-12-01

    This study introduces a noise reduction technique that uses a complex bilateral filter. A bilateral filter is a nonlinear filter originally developed for images that can reduce noise while preserving edge information. It is an attractive filter and has been used in many applications in image processing. When it is applied to an acoustical signal, small-amplitude noise is reduced while the speech signal is preserved. However, a bilateral filter cannot handle noise with relatively large amplitudes owing to its innate characteristics. In this study, the noisy signal is transformed into the time-frequency domain and the filter is improved to handle complex spectra. The high-amplitude noise is reduced in the time-frequency domain via the proposed filter. The features and the potential of the proposed filter are also confirmed through experiments.

    To study the natural history and retinal findings associated with the intraretinal and subretinal fibrovascular tissues that develop in the late phases of bilateral juxtafoveal telangiectasis. The records of 10 patients (11 eyes) with bilateral juxtafoveal telangiectasis who developed these fibrovascular tissues were examined. Throughout the follow-up period (average 44 months), only 2 eyes (18%) lost 2 or more lines of vision; the final visual acuities were similar for the eyes both with and without fibrovascular tissues. Sixty-four percent of fibrovascular tissues showed little to no growth. Eyes with fibrovascular tissue commonly had retinal pigment epithelial hyperplasia (72%), draining retinal venules (82%), and retinal vascular distortion (64%). Fibrovascular tissues of bilateral juxtafoveal telangiectasis have little proliferative potential and minimal effects on visual acuity. Nevertheless, these fibrovascular tissues do remodel over time, leading to retinal vascular distortion. Given these benign findings, the role of laser photocoagulation treatment of these tissues is questionable.

The outcome at 6 months after surgery was excellent with visual acuities of 6/6 in both eyes. Improved availability of endotamponade agents allows repair of bilateral GRTs to be done at the same time, with good surgical outcomes.

    To our knowledge, bilateral supernumerary kidney is a very rare renal abnormality and there are five cases presented in the literature. It is difficult to diagnose supernumerary kidney and clinicians have not detected most cases preoperatively. Laboratory and imaging studies were acquired and carefully examined. The normal laboratory tests were found. Emergency ultrasonography was performed and they revealed no signs of parenchymal abnormality in both kidneys. Serial imaging study including enhanced computed tomography (CT) was performed. An imaging study identified bilateral supernumerary kidney with expanded collecting systems. On each side, significant rotation anomaly was found. In addition, there were two different renal arteries originating from the aorta. This report presents radiological determinations of supernumerary kidney bilaterally in a young man. We think that CT commonly appears to be enough for the diagnosis of supernumerary kidneys

    Full Text Available Bilateral acute iris transillumination (BAIT is a recently defined disease characterized with bilateral acute, severe pigment dispersion of iris and pupil sphincter paralysis. The etiopathogenesis of the disease is unknown, but antibiotics such as moxifloxacin, clarithromycin, viral infections, and fumigation therapies were considered as probable etiologic factors. A 33-year-old female was referred to our clinic for acute iridocyclitis refractory to azathioprine, colchicum and corticosteroid treatments. Ophthalmic examination revealed bilateral pigment dispersion, significant iris transillumination, heavy pigment deposition in iridocorneal angle, and elevated intraocular pressure. Upon systemic evaluation she was found to have bacterial urinary tract infection. BAIT is an important cause of pigment dispersion and clinicians must be vigilant for this condition to avoid unnecessary diagnostic tests and treatment.

    Clear cell sarcoma of the kidney (CCSK) accounts for 2-5% of all pediatric renal malignancies, and is known for its propensity to metastasize to bone and other sites. We are reporting two cases with bilateral CCSK that were diagnosed at our institution. One patient initially presented with bilateral renal masses, as well as pulmonary, hepatic and bone metastasis; while other present only with bilateral masses with no evident distant metastasis. Both patients received aggressive neo-adjuvant chemotherapy to decrease tumor size. One patient completed his designated treatment and initially showed complete remission (CR); eventually suffering from relapse. The other patient’s tumor progressed during the course of chemotherapy. Both cases manifested brain dissemination at the time of relapse or progression. This emphasizes the importance of staging stratification in CCSK. This also illustrates CCSK’s ability to metastasize to bone and other sites including the brain (a primary relapse site in our cases)

    Currently, no consistent evidence-based guidelines for the management of synchronous bilateral breast cancer (SBBC) exist and it is uncertain how presenting with SBBC affects patients' prognosis. We conducted a review of studies analyzing the association between SBBC and prognosis. The studies...... that reported adjusted effect measures were included in meta-analyses of effect of bilaterality on breast cancer mortality. From 57 initially identified records 17 studies from 11 different countries including 8,050 SBBC patients were included. The quality of the studies varied but was generally low with small...... sample sizes, and lack of consistent, detailed histo-pathological information. When doing meta-analysis on the subgroup of studies that provided adjusted effect estimates on breast cancer mortality (nine studies including 3,631 SBBC cases), we found that bilaterality in itself had a negative impact...

    Hintze, Justin M; Gnagi, Sharon H; Lott, David G

    2018-05-01

    Bilateral true vocal fold paralysis is rarely attributable to inflammatory diseases. Sarcoidosis is a rare but important etiology of bilateral true vocal fold paralysis by compressive lymphadenopathy, granulomatous infiltration, and neural involvement. We describe the first reported case of sarcoidosis presenting as bilateral vocal fold immobility caused by direct fixation by granulomatous infiltration severe enough to necessitate tracheostomy insertion. In addition, we discuss the presentation, the pathophysiology, and the treatment of this disease with a review of the literature of previously reported cases of sarcoidosis-related vocal fold immobility. Sarcoidosis should therefore be an important consideration for the otolaryngologist's differential diagnosis of true vocal fold immobility. Copyright © 2018 The Voice Foundation.

    In evaluating patients sustaining bilateral isolated internal orbital fractures, the authors have observed both similar fracture locations and also similar expansion of orbital volumes. In this study, we aim to investigate if there is a propensity for the 2 orbits to fracture in symmetrically similar patterns when sustaining similar trauma. A retrospective chart review was performed studying all cases at our institution of bilateral isolated internal orbital fractures involving the medial wall and/or the floor at the time of presentation. The similarity of the bilateral fracture locations was evaluated using the Fisher's exact test. The bilateral expanded orbital volumes were analyzed using the Wilcoxon signed-rank test to assess for orbital volume similarity. Twenty-four patients with bilateral internal orbital fractures were analyzed for fracture location similarity. Seventeen patients (70.8%) had 100% concordance in the orbital subregion fractured, and the association between the right and the left orbital fracture subregion locations was statistically significant (P < 0.0001). Fifteen patients were analyzed for orbital volume similarity. The average orbital cavity volume was 31.2 ± 3.8 cm on the right and 32.0 ± 3.7 cm on the left. There was a statistically significant difference between right and left orbital cavity volumes (P = 0.0026). The data from this study suggest that an individual who suffers isolated bilateral internal orbital fractures has a statistically significant similarity in the location of their orbital fractures. However, there does not appear to be statistically significant similarity in the expansion of the orbital volumes in these patients.

    Outcome assessment after double level tibial lengthening in patients with dwarfism. Fourteen patients with dwarfism were analyzed after bilateral simultaneous double level tibial lengthening. Average age was 15.1 years. Average lengthening was 13.5 cm. The two levels were lengthened by an average of 7.5 cm proximally and 6.0 cm distally. Concomitant deformities were also addressed during lengthening. External fixation treatment time averaged 8.8 months. Healing index averaged 0.7 months/cm. Bilateral tibial lengthening for dwarfism is difficult, but the results are usually quite gratifying.

    Full Text Available Spontaneous tegmen tympani defects are rare with even rarer bilateral cases. The symptoms are nonspecific; hence, a high index of suspicion is required to prevent serious intracranial complications. We present a case of spontaneous bilateral tegmen tympani defects with associated meningoencephalocoeles in a 54-year-old male who presented with the signs and symptoms of severe meningitis. After careful workup which included a lumbar puncture, CT and MRI scans, both defects were repaired using a middle fossa approach. The patient made an uneventful recovery with complete cessation of otorrhoea and improvement in his hearing.

    With most Newly Independent States (NIS) of the former Soviet Union becoming parties to the Non-Proliferation Treaty as Non-Nuclear Weapon States, there has been an acute need in these states for considerable assistance for the establishment of the necessary structure and resources to ensure that their commitments to non-proliferation are fully implemented in a timely manner. A number of IAEA Member States have offered and are now providing assistance to the NIS on a bilateral level to set up an appropriate State System of Accounting and Control (SSAC) which includes Import/Export Control and Physical Protection of Nuclear Material in each state. The IAEA and these Member States established the Co-ordinated Technical Support Programme (CTSP) to ensure that the support given to the NIS was done in a co-ordinated and transparent manner and to avoid duplication of effort. The IAEA has played a coordinating role for the past 5 years by helping to identify detailed needs in individual States, by providing a platform for Member States to identify areas where they could provide the optimum support, and in developing and preparing the Co-ordinated Technical Support Plans. The IAEA organises annual meetings in Vienna attended by all donor and recipient countries to review the focus and implementation status of the co-ordinated technical support activities. A position statement is made by each donor and recipient country, and views and experiences are exchanged. The contents of the CTSPs and the role of the Agency in monitoring the progress of the individual tasks are reviewed in this paper. A summary comparing the implementation status of the Programme by each country is presented. (author)

    Hydrogen exchange (HX) monitored by mass spectrometry (MS) is a powerful analytical method for investigation of protein conformation and dynamics. HX-MS monitors isotopic exchange of hydrogen in protein backbone amides and thus serves as a sensitive method for probing protein conformation...... and dynamics along the entire protein backbone. This chapter describes the exchange of backbone amide hydrogen which is highly quenchable as it is strongly dependent on the pH and temperature. The HX rates of backbone amide hydrogen are sensitive and very useful probes of protein conformation......, as they are distributed along the polypeptide backbone and form the fundamental hydrogen-bonding networks of basic secondary structure. The effect of pressure on HX in unstructured polypeptides (poly-dl-lysine and oxidatively unfolded ribonuclease A) and native folded proteins (lysozyme and ribonuclease A) was evaluated...

    To evaluate the mammographic and clinical features of bilateral breast cancer. We retrospectively reviewed clinical records(n=23) and mammograms (n=15) of 23 patients with bilateral breast cancer. Patients' age, location of the tumor and pathologic staging were determined from clinical records. Mammographic features were classified as spiculated mass, nonspiculated mass, mass with microcalcification, microcalcification only, asymmetric density, and normal. Of the 23 cases of bilateral breast cancer, 8(34.8%) were synchronous and 15(65.2%) were metachronous. Age at diagnosis of cancer in the first breast was between 27 and 59(mean 43) years ; there was no statistically significant difference in mean age between patients with synchronous and metachronous cancer. The mean interval between the diagnosis of each lesion of the metachronous pairs was 9.1 years. In 11 of 23 cases(48%), tumors were locaated in the same quadrant, and in the other 12 cases(52%), they were in different quadrant. At mammography, five of 15 metachronous cancers(33%) were similar in appearance and 10 pairs(67%) were different. In 4 of 23 cases(17%), cancer in the first breast was at stage 0 and stage 1, and in 13 of 23(57%), cancer in the second breast was at this same stage. In bilateral breast cancer, the two breasts frequently show different mammographic features. Cancer of the second breast was at an early stage; this suggest that regular examination and mammography are important and can allow early detection of contralateral breast cancer

Departamento de Medicina e Cirurgia Veterinária, Instituto de Veterinária, Universidade Federal Rural do Rio de Janeiro, BR 465 Km 7, Seropédica RJ 23890-000, Brasil. E-mail: saulocaldas@hotmail.com A case of bilateral queilosquise in a cattle two years old was reported. Clinically, there was cachexia, difficulty in grasping food and water intake. The clinical examination revealed that the nasal orifices were discontinuous with the upper lip, which allowed communication between the nostrils and mouth in its rostral portion, crowding of incisors (tweezers, as well as exposure of medium and the 2nd corner and of the tongue. In this case, the bilateral queilosquise was the result of flaws in fusion of the maxillary process and the medial nasal process and its surroundings, probably due to mineral deficiencies of pregnant cow. This pathogenesis was suggested by excluding other possible causes, the knowledge of the existence of mineral deficiencies in the region where the event occurred and bad nutritional status of pregnant female.

    A case of bilateral fibrotic contracture of the infraspinatus muscles in a five-year-old Belgian Shepherd dog is described. The dog was presented with progressive forelimb lameness with postural and gait abnormalities three months after an episode of overexertion. When walking, the lower part of both forelimbs swung in a lateral arc causing a circumduction movement and in the standing position, the dog showed elbow adduction with external rotation of the distal part of both front limbs. Orthopaedic examination revealed bilateral atrophy of both infraspinatus and supraspinatus muscles and restriction in the range of motion of both shoulders, especially when attempting abduction and flexion. No specific findings were observed in the shoulder or elbow radiographs but hyperechogenic areas were evident in the ultrasonographic examination of both infraspinatus muscles. A diagnosis of fibrotic contracture of both infraspinatus muscles was established and bilateral tenectomy of the insertion tendons of the infraspinatus muscles was performed. Complete recovery of the animal was achieved after the surgery, which was confirmed in a long-term follow-up (10 months). In conclusion, physical examination and ultrasonography allowed a proper diagnosis of the condition, and tenectomy of the infraspinatus muscles resulted in a complete recovery of the patient even with bilateral involvement.

    Full Text Available The article deals with the author’s interpretation of the process of teaching profession specific bilateral translation to student teacher of English in the Master’s program. The goal of the model of teaching profession specific bilateral translation development is to determine the logical sequence of educational activities of the teacher as the organizer of the educational process and students as its members. English and Ukrainian texts on methods of foreign languages and cultures teaching are defined as the object of study. Learning activities aimed at the development of student teachers of English profession specific competence in bilateral translation and Translation Proficiency Language Portfolio for Student Teachers of English are suggested as teaching tools. The realization of the model of teaching profession specific bilateral translation to student teachers of English in the Master’s program is suggested within the module topics of the academic discipline «Practice of English as the first foreign language»: Globalization; Localization; Education; Work; The role of new communication technologies in personal and professional development. We believe that the amount of time needed for efficient functioning of the model is 48 academic hours, which was determined by calculating the total number of academic hours allotted for the academic discipline «Practice of English as the first foreign language» in Ukrainian universities. Peculiarities of the model realization as well as learning goals and content of class activities and home self-study work of students are outlined.

    1996-01-01

    Purpose: To assess outcome of patients with bilateral breast carcinoma treated with bilateral breast conserving surgery with radiation therapy (CS+RT) and to compare their outcome to (1) patients with unilateral disease treated with CS+RT and (2) patients of comparable stage treated with bilateral mastectomy. Methods and Materials: The charts of all patients with the diagnosis of breast cancer treated with CS+RT at our facilities prior to 1993 were reviewed to identify patients with bilateral disease. A total of 50 patients identified as having bilateral breast cancer conservatively treated(BCT) served as the index population. Out of the 50 patients, 23 presented with synchronous bilateral breast cancer and 27 presented with metachronous bilateral breast cancer. A group of 984 patients with unilateral breast cancer (UCT) treated with CS+RT during the same time interval served as the first control group. A second control group was comprised of 42 patients with early stage bilateral breast cancer presenting during the same time interval treated with bilateral mastectomy (BMAST). Patients who had locally advanced disease in either breast or those patients treated exclusively for lobular carcinoma in situ in either breast were excluded from the analysis. Of the 42 BMAST patients, 33 presented with synchronous disease and nine presented with metachronous disease. Local-regional relapse rates were calculated from the date of treatment of each breast. Overall survival and distant relapse rates were calculated from the date of treatment of the second breast cancer diagnosed. Survival curves were calculated via the life table method and statistical comparisons between curves were performed using the log rank statistic. Chi square analysis was used to detect differences between categorical variables. Results: As of December 1995, the median follow-up of the bilateral conservatively treated patient population was 9.4 years. No statistically significant differences were noted

    Full Text Available Introduction: The incidence of tumors of the upper urothelium is high in our country, apart from their relation to specific regions (BEN and PBEN and their frequent bilateralism. Bilateral forms are present in significant percentage and are followed, in most cases, by renal failure, which speaks in favor of conservative surgery, if possible. Objective: The aim of the study was to present epidemiological, pathoanatomical and clinical characteristics of bilateral tumors of the upper urothelium and evaluate the Results of their treatment. Method: Our retrospective study analyzed 12 patients with bilateral tumors of the upper urothelium who were treated in the period from 1992 to 1996, according to their epidemiological, clinical, pathoanatomical and pathohistological characteristics, type of surgical treatment and relevant success. Results: In the observed period, bilateral tumors of the upper urothelium were found in 8.2% of our patients. In the group of 12 patients, 5 females and 7 males, 11 cases were from the region of Balkan Endemic Nephropathy (BEN. Renal failure was recorded in high percentage (66%. Radical surgical treatment - total nephroureterectomy was performed in 9 kidney units, and conservative operation in 15 units. Relapse significantly depended on tumor stage and grade, not on type of surgical treatment in the majority of cases. Five-year survival was 58.33%; major cause of death was associated with further evolution of tumor, recurrence and tumor dissemination, respectively, while renal failure complications were the cause of death in one case. Conclusion: The success of treatment mainly depends on tumor stage and grade and not on type of surgical Method in conservative treatment, but renal failure and its complications are an important risk factor in these patients.

    A network of formal and informal bilateral arrangements for the exchange of nuclear safety information is being established by the U.S. Nuclear Regulatory Commission. For developing countries, such arrangements can provide ready access to the extensive, fully documented safety analyses and safety research results that NRC has accumulated. NRC has been receiving foreign visitors at a rate of about 500 per year, largely for discussions of safety and licensing questions related to light water reactors. Exchanges also are taking place on the safety of advanced reactors. A special interest of the NRC is in providing for reciprocal communicaion, at the earliest possible time, of important problems, decisions and other actions on nuclear safety matters. For example, it is essential that a newly-discovered problem in a nuclear reactor be brought immediately to the attention of other governments which are responsible for the safety of similar reactors. Definite progress has been made in the U.S. Freedom of Information Act. Certain exchanges have taken place on this basis. Experience in the establishment and operation of NRC's bilateral exchange arrangements is summarized. A typical exchange with the regulatory authority of country building its first power reactor is described

    Whether unilateral or bilateral drainage should be performed for malignant hilar biliary obstruction remains a matter of debate. Although a Y-stent with a central wide-open mesh facilitates bilateral stent placement, it has its own limitations. This study aims to evaluate the feasibility and efficacy of a newly designed Y-configured bilateral self-expanding metallic stent (SEMS) for the treatment of hilar biliary obstruction. In this retrospective study, 14 consecutive patients with unresectable malignant hilar biliary obstruction (Bismuth type II or higher), who underwent placement of a newly designed Y-configured bilateral SEMS for hilar biliary obstruction from April 2013 to March 2015, were included into this study. Data on technical success, clinical success, stent patency, complications and patient survival were collected. Technical and clinical success was 100 and 92.9 %, respectively. Mean serum bilirubin level was significantly decreased 1 month after stent placement (P hilar biliary obstruction using port docking deployment.

    2015-01-01

    Full Text Available Bilateral facial paralysis caused by bilateral temporal bone fracture is a rare clinical entity, with seven cases reported in the literature to date. In this paper, we describe a 40-year-old male patient with bilateral facial paralysis and hearing loss that developed after an occupational accident. On physical examination, House-Brackmann (HB facial paralysis of grade 6 was observed on the right side and HB grade 5 paralysis on the left. Upon temporal bone computed tomography (CT examination, a fracture line exhibiting transverse progression was observed in both petrous temporal bones. Our patient underwent transmastoid facial decompression surgery of the right ear. The patient refused a left-side operation. Such patients require extensive monitoring in intensive care units because the presence of multiple injuries means that facial functions are often very difficult to evaluate. Therefore, delays may ensue in both diagnosis and treatment of bilateral facial paralysis.

    2009-01-01

    A bilateral subtraction filter has been implemented as a hardware module in the form of a field-programmable gate array (FPGA). In general, a bilateral subtraction filter is a key subsystem of a high-quality stereoscopic machine vision system that utilizes images that are large and/or dense. Bilateral subtraction filters have been implemented in software on general-purpose computers, but the processing speeds attainable in this way even on computers containing the fastest processors are insufficient for real-time applications. The present FPGA bilateral subtraction filter is intended to accelerate processing to real-time speed and to be a prototype of a link in a stereoscopic-machine- vision processing chain, now under development, that would process large and/or dense images in real time and would be implemented in an FPGA. In terms that are necessarily oversimplified for the sake of brevity, a bilateral subtraction filter is a smoothing, edge-preserving filter for suppressing low-frequency noise. The filter operation amounts to replacing the value for each pixel with a weighted average of the values of that pixel and the neighboring pixels in a predefined neighborhood or window (e.g., a 9 9 window). The filter weights depend partly on pixel values and partly on the window size. The present FPGA implementation of a bilateral subtraction filter utilizes a 9 9 window. This implementation was designed to take advantage of the ability to do many of the component computations in parallel pipelines to enable processing of image data at the rate at which they are generated. The filter can be considered to be divided into the following parts (see figure): a) An image pixel pipeline with a 9 9- pixel window generator, b) An array of processing elements; c) An adder tree; d) A smoothing-and-delaying unit; and e) A subtraction unit. After each 9 9 window is created, the affected pixel data are fed to the processing elements. Each processing element is fed the pixel value for

    Full Text Available Bilateral PDA dependent pulmonary circulation with right and left pulmonary artery discontinuity is very rare. Limited data available for bilateral PDA stenting. Bilateral PDA stenting in nonconfluent pulmonary arteries is challenging procedure but can be considered as an option in the management of complex conditions like this. 12 days old Preterm (36 weeks gestation male baby with birth weight of 2.6 kg developed respiratory distress with severe cyanosis and desaturation upto 50%. Baby was intubated and started on Prostaglandin 0.05 mic/kg/mt. His saturation improved to 80%. Echocardiogram showed complex cyanotic heart disease, Situs ambiguous, dextrocardia, complete unbalanced AV septal defect, pulmonary atresia , nonconfluent small branch pulmonary arteries supplied by the bilateral patent ductus arteriosus (PDA from right aortic arch and all four pulmonary veins form a confluence and drain into superior vena cava(SVC through vertical vein with no obstruction. Baby was taken up for PDA stenting. descending aortogram showed right aortic arch with vertical tortuous duct to right pulmonary artery (RPA and another short duct with acute angle from left subclavian artery to left pulmonary artery (LPA . Both ducti stented with coronary stents. Vertical vein angiogram showed both lungs drain to a confluence and then to SVC via ascending vertical vein with no obstruction. After stenting lung perfusion improved and the baby was stable and maintained 80% saturation on room air. Bilateral PDA dependent pulmonary circulation with right and left pulmonary artery discontinuity is very rare. Our case is unique with Heterotaxy, TAPVC, Dextrocardia and double ducti. Eventhough bilateral ductal stenting is technically challenging it is successful through femoral artery approach.

    A heat exchanger such as forms, for example, part of a power steam boiler is made up of a number of tubes that may be arranged in many different ways, and it is necessary that the tubes be properly supported. The means by which the tubes are secured must be as simple as possible so as to facilitate construction and must be able to continue to function effectively under the varying operating conditions to which the heat exchanger is subject. The arrangement described is designed to meet these requirements, in an improved way. The tubes are secured to a member extending past several tubes and abutment means are provided. At least some of the abutment means comprise two abutment pieces and a wedge secured to the supporting member, that acts on these pieces to maintain the engagement. (U.K.)

    The exchange of tax information has received ample attention recently, due to a number of recent headlines on aggressive tax planning and tax evasion. Whilst both participating tax authorities will gain when foreign investments (FDI) are bilateral, we demonstrate that FDI receiving nations will lose in asymmetric situations. We solve a bargaining model that proves that tax information exchange will only happen voluntarily with compensation for this loss. We then present empirical evidence in ...

    Full Text Available Elastofibroma dorsi is a rare, slow-growing soſt tissue tumor of the chest wall. The tumor typically located under the lower pole of the scapula. A 57-year-old woman who had retiredas a teacher, presented with a 1-year history of pain on the back and with a 3-month history of swelling located under the leſt scapula. Computed tomography and magnetic resonance imaging showed bilateral, solid soſt tissue tumors under the scapula. She underwent total resection of the tumor on the leſt side. Tumor was diagnosed histopathologically as elastofibroma. Elastofibroma dorsi can be undetermined because of its localization. Radiological examination is important especially on diagnosis of bilateral localization.

    2003-07-01

    Incontinentia Pigmenti is an X-linked dominant neurocutaneous disorder with central nervous system manifestations in 30% of cases, including seizures and mental retardation. Ischemic or hemorrhagic cerebrovascular accidents have been reported rarely in incontinentia pigmenti. Chart review and literature search was performed following identification of the index case. We describe a patient with incontinentia pigmenti who developed bilateral cerebrovascular accidents in the neonatal period, with resultant severe neurologic sequelae. This is the second reported case of bilateral cerebrovascular accidents in a patient with incontinentia pigmenti. This finding may be secondary to cerebrovascular anomalies, similar to those observed in the retina. Recognition of cerebrovascular accidents as a complication of incontinentia pigmenti will hopefully lead to earlier recognition and treatment.

    We report the occurrence of a bilateral pneumothoraces after unilateral central venous catheterization of the right subclavian vein in a 70-year-old patient. The patient had no history of pulmonary or pleural disease and no history of cardiothoracic surgery. Two days earlier, she had a median laparotomy under general and epidural anaesthesia. Prior to the procedure, the patient was hemodynamically stable and her transcutaneous oxygen saturation was 97% in room air. We punctured the right pleural space before cannulation of the right subclavian vein. After the procedure, the patient slowly became hemodynamically instable with respiratory distress. A chest radiograph revealed a complete left-side pneumothorax and a mild right-side pneumothorax. The right-side pneumothorax became under tension after left chest tube insertion. The symptoms finally resolved after insertion of a right chest tube. After a diagnostic work-up, we suspect a congenital “Buffalo chests” explaining bilateral pneumothoraces and a secondary tension pneumothorax. PMID:19901997

    Localized primary periosteal amyloid tumors are extremely rare. A case of bilateral tibial amyloid tumor is presented. A 62-year-old woman initially presented with a painful mass in the anterior aspect of the right leg. There was no evidence of underlying systemic disease, including chronic infection or malignancy. Based on the results of resistance with Congo red staining to treatment with potassium permanganate and positivity for kappa light chain, we classified this particular case as AL-type amyloidosis. The patient noticed a swelling in the opposite leg 2 years later. The second tumor was also an AL-type amyloidoma. Amyloid tumors are generally solitary. This is the first case of bilateral periosteal amyloid tumors of the AL-type occurring in the tibiae. (orig.)

    1990-01-01

    Three patients developed bilateral breast cancer at 10 to 24 years after mantle irradiation for locally or systemically advanced Hodgkin's disease (HD). Four of the six cancers in the three patients were detected only by mammography. Pathologically, five of the cancers were intraductal carcinomas (four with an invasive component) with one being a lobular carcinoma. Five of the six lesions were Stage I pathologically without evidence of axillary nodal involvement. It is recommended that female patients with Hodgkin's disease who have received mantle irradiation as part of the therapy for their Hodgkin's disease and who are observed for 10 or more years after completion of mantle irradiation be considered at risk for the development of breast cancer. Such patients should be monitored appropriately by routine bilateral mammograms to increase the early detection of early stage lesions

    Full Text Available Xanthogranulomas (XGRs of the choroid plexus are rare, asymptomatic, and benign lesions usually found incidentally. Here, we present a case of a 47-year-old male with bilateral XGR of the choroid plexus with periventricular edema and discuss our case in relation to a review of existing literature pertaining to the radiology of XGRs. To the best of our knowledge, this is the first reported case of bilateral trigonal XGR causing brain edema without ventricular dilatation. Despite the fact that they can cause hydrocephalus, XGRs are silent and benign lesions. Although the etiopathology of XGRs remains poorly understood, enhanced imaging analyses may provide additional information regarding edema and focal white matter signal changes.

    Full Text Available Aspergillus endophthalmitis is a devastating inflammatory condition of the intraocular cavities that may result in irreparable loss of vision and rapid destruction of the eye. Almost all cases in the literature have shown an identified source causing aspergillus endophthalmitis as a result of direct extension of disease. We present a rare case of bilateral aspergillus endophthalmitis. A 72-year-old woman with a history of diabetes mellitus, congenital Hirschsprung disease, and recent culture-positive candida pyelonephritis with hydronephrosis status post-surgical stent placement presented with difficulty opening her eyes. She complained of decreased vision (20/200 with pain and redness in both eyes – right worse then left. Examination demonstrated multiple white fungal balls in both retinas consistent with bilateral fungal endophthalmitis. Bilateral vitreous taps for cultures and staining were performed. Patient was given intravitreal injections of amphotericin B, vancomycin, ceftazidime, and started on oral fluconazole. Patient was scheduled for vitrectomy to decrease organism burden and to remove loculated areas of infection that would not respond to systemic antifungal agents. Four weeks after initial presentation, the fungal cultures revealed mold growth consistent with aspergillus. Patient was subsequently started on voriconazole and fluconazole was discontinued due to poor efficacy against aspergillus. Further workup was conducted to evaluate for the source of infection and seeding. Transthoracic cardiogram was unremarkable for any vegetation or valvular abnormalities. MRI of the orbits and sinuses did not reveal any mass lesions or bony destruction. CT of the chest was unremarkable for infection. Aspergillus endophthalmitis may occur because of one of these several mechanisms: hematogenous dissemination, direct inoculation by trauma, and contamination during surgery. Our patient's cause of bilateral endophthalmitis was through an

    A paradigmatic example of an emotional bias in decision making is the framing effect, where the manner in which a choice is posed ? as a potential loss or a potential gain ? systematically biases an ensuing decision. Two fMRI studies have shown that the activation in the amygdala is modulated by the framing effect. Here, contrary to an expectation based on these studies, we show that two patients with Urbach-Wiethe (UW) disease, a rare condition associated with congenital, complete bilateral ...

    Operational Experience At the end of the first full-year running period of LHC, CMS is established as a reliable, robust and mature experiment. In particular common systems and infrastructure faults accounted for <0.6 % CMS downtime during LHC pp physics. Technical operation throughout the entire year was rather smooth, the main faults requiring UXC access being sub-detector power systems and rack-cooling turbines. All such problems were corrected during scheduled technical stops, in the shadow of tunnel access needed by the LHC, or in negotiated accesses or access extensions. Nevertheless, the number of necessary accesses to the UXC averaged more than one per week and the technical stops were inevitably packed with work packages, typically 30 being executed within a few days, placing a high load on the coordination and area management teams. It is an appropriate moment for CMS Technical Coordination to thank all those in many CERN departments and in the Collaboration, who were involved in CMS techni...

    Operational Experience Since the closure of the detector in February, the technical operation of CMS has been quite smooth and reliable. Some minor interventions in UXC were required to cure failures of power supplies, fans, readout boards and rack cooling connections, but all these failures were repaired in scheduled technical stops or parasitically during access dedicated to fixing LHC technical problems. The only occasion when CMS had to request an access between fills was to search for the source of an alarm from the leak-detection cables mounted in the DT racks. After a few minutes of diagnostic search, a leaking air-purge was found. Replacement was complete within 2 hours. This incident demonstrated once more the value of these leak detection cables; the system will be further extended (during the end of year technical stop) to cover more racks in UXC and the floor beneath the detector. The magnet has also been operating reliably and reacted correctly to the 14s power cut on 29 May (see below). In or...

    Burkitt lymphoma, is described as an aggressive form of non-Hodgkin lymphoma of B cells which occurs most often in children and young adults, ovarian lymphoma can appear as a primary lesion or more commonly referred to as a metastasis. Primary ovarian lesions are rare manifestations corresponding to 0.5% of non-Hodgkin lymphoma and 1.5% of ovarian tumors. Clinic case: 31 years old female with general weakness, march incapacity, dyspnea, hyporexia, fever, diaphoresis, weight loss of 20 kg, flat abs with abdominal pain; Ca125 610 U/ml. Abdominal computed tomography shows a solid aspect tumor which affects the right pelvic cavity. Bilateral ovarian tumors were removed. Microscopically, both lesions show a "starry sky" pattern composed by a monotonous infiltration of lymphocytes mixed with large and clear macrophages, several atypical mitoses, and necrosis and hemorrhage areas. Immunohistochemistry was positive for CD10, CD20, and negative for CD3 and high Ki67 proliferation index. Bilateral ovarian Burkitt's lymphoma was diagnosed. Bilateral ovarian Burkitt's lymphoma is a rare entity, with a variability of presentations, the abdominal pain and abdominal tumors are the most frequent. The patient's prognosis at short term is poor, therefore it's necessary to know this entity and make an early diagnosis.

    1977-01-01

    Over 300 cases of femoral neck fractures following radiotherapy for intrapelvic malignant tumor have been reported in various countries since Baensch reported this disease in 1927. In Japan, 40 cases or so have been reported, and cases of bilateral femoral neck fractures have not reached to ten cases. The authors experienced a case of 75 year-old female who received radiotherapy for cancer of the uterus, and suffered from right femoral neck fracture 3 months after and left femoral neck fracture one year and half after. As clinical symptoms, she had not previous history of trauma in bilateral femurs, but she complained of a pain in a hip joint and of gait disturbance. The pain in left femoral neck continued for about one month before fracture was recognized with roentgenogram. As histopathological findings, increase of fat marrow, decrease of bone trabeculae, and its marked degeneration were recognized. Proliferation of some blood vessels was found out, but thickness of the internal membrane and thrombogenesis were not recognized. Treatment should be performed according to degree of displacement of fractures. In this case, artificial joint replacement surgery was performed to the side of fracture of this time, because this case was bilateral femoral neck fractures and the patient had received artificial head replacement surgery in the other side of fracture formerly.

    A 66-year-old male was admitted to our neurosurgical floor because of double vision and gait disturbance. Neurological examinations revealed bilateral 6th nerve palsy with both eyes pointing toward the midline. Initially, using a tentative diagnosis of intracranial mass lesions, especially localized at the base of the skull, computerized tomography of the head, cerebral angiography, orbital venography, and metrizamide CT cisternography were performed; the findings were normal. An orbital CT scan showed an enlargement of the bilateral medial rectus muscles, and the thyroid functions of T 3 and T 4 and the T 3 uptake were all elevated, which was compatible with the diagnosis of Graves' disease. The limitations of both eyeballs were considered to be due not to the 6th nerve palsy, but to the hypertrophy of the bilateral medial rectus muscles. We neurosurgeons should recall Graves' disease as well as intracranial lesions, cerebrovascular disease, and post-traumatic sequelae when examining a patient who presents limitations of external ocular movement.

    Image smoothing is a fundamental operation in computer vision and image processing. This work has two main thrusts: (1) implementation of a bilateral filter suitable for use in smoothing, or denoising, 3D volumetric data; (2) implementation of the 3D bilateral filter in three different parallelization models, along with parallel performance studies on two modern HPC architectures. Our bilateral filter formulation is based upon the work of Tomasi [11], but extended to 3D for use on volumetric data. Our three parallel implementations use POSIX threads, the Message Passing Interface (MPI), and Unified Parallel C (UPC), a Partitioned Global Address Space (PGAS) language. Our parallel performance studies, which were conducted on a Cray XT4 supercomputer and aquad-socket, quad-core Opteron workstation, show our algorithm to have near-perfect scalability up to 120 processors. Parallel algorithms, such as the one we present here, will have an increasingly important role for use in production visual analysis systems as the underlying computational platforms transition from single- to multi-core architectures in the future.

    Patellar fractures are uncommon injuries and account for approximately 1% of all fractures. In this article, a 35-year-old male patient who sustained a collision deceleration accident with bilateral comminuted transverse patellar fractures is presented. For this patient, open reduction and internal fixation with tension band technique, using two Kirschner wires and cerclage wire was applied for both fractures. At the first postoperative day, isometric quadriceps and active range of motion exercises were begun and the patient was allowed to walk full weight bearing with two crutches while both extremities were immobilized in a hinged brace allowing maximum 30 degrees of flexion. At postoperative fourth week brace immobilization was terminated. However, the patient was advised to use crutches for two weeks more to prevent any complications that may arise during walking because of the bilaterally of the injury. At six weeks solid union was achieved. During the last visit at postoperative second year, the patient had no complaints and the range of motion was full. In this paper a case of bilateral patella fractures is presented as a consequence of a dashboard injury, and the pathomechanical and therapeutical aspects of such an injury is discussed.

    The current international energy trade governance system is fragmented and multi-layered. Streamlining it for greater legal cohesiveness and international political and economic cooperation would promote global energy security. The current article explores three levels of energy trade governance: multilateral, regional and bilateral. Most energy-rich countries are part of the multilateral trading system, which is institutionalized by the World Trade Organization (WTO). The article analyzes the multilateral energy trade governance system by focusing on the WTO and energy transportation issues. Regionally, the article focuses on five major regional agreements and their energy-related aspects and examines the various causes that explain the proliferation of regional trade agreements, their compatibility with WTO law, and then provides several examples of regional energy trade governance throughout the world. When it comes to bilateral energy trade governance, this article only addresses the European Union’s (EU) bilateral energy trade relations. The article explores ways in which gaps could be filled and overlaps eliminated whilst remaining true to the high-level normative framework, concentrating on those measures that would enhance EU energy security.

    • Gorlin syndrome (GS, also known as nevoid basal cell carcinoma syndrome (NBCCS, is a rare inherited multisystem disorder. This paper presents a 22-years-old Iranian woman with this syndrome whose past history was multiple keratocysts of maxillary bone. She was referred to gynecology clinic with the chief complaint of irregular menses and vaginal spotting. On examination, frontal bossing and hypertelorism were detected. Physical examination of genitalia disclosed bilateral adnexal masses. Pelvic ultrasound showed two solid, echogenous and calcified masses measuring 100*50*10 & 60*50*45 mm in the left and right ovaries, respectively. The patient underwent right oophorectomy and ovarian mass resection with preservation of intact ovarian tissue on the left side. On frozen and permanent histological sections, bilateral and calcified ovarian fibromas were diagnosed. Surprisingly, during the last follow-up one year after the surgery, we found that our patient was expecting a baby. It can be concluded that in the presence of bilateral and calcified ovarian fibromas, the possibility of GS should be considered. Accurate diagnosis is only possible with close attention to the familial and past medical history and physical examination. In these patients, careful follow up for detecting malignancies and other complications is highly recommended.

    The bilateral collimator has been widely adopted for obtaining two simultaneous views of the heart in nuclear cardiology. As an additional useful clinical application of the bilateral collimator, it has been used for parasternal lymphoscintigraphy. Lymphography with a contrast medium for the parasternal lymphatics is technically very difficult and the radionuclide method is adopted. Lymphoscintigraphy has been used in order to determine the existence of malignant invasion to the lymph nodes, and also to find the depth of the lymph node as a guide to operation and radiation therapy of the nodes.

    Review of a case of paraosseous extramedullary hematopoiesis (EMH) affecting the maxillary sinuses and retro-orbital spaces imitating bilateral orbital cellulitis. Maxillofacial EMH causes diagnostic/therapeutic challenges. This case report describes a 4-year-old African American male with sickle cell disease (HbSS) who presented with bilateral orbitofacial swelling. Diagnosis was made with imaging and confirmed with tissue sampling. Partial exchange transfusion was utilized to stop the progression of maxillofacial EMH and to treat the patient's chronic anemia. Follow-up MRI showed regression of orbital and retro-orbital involvement. Early treatment with conservative modalities and close observation may prevent need for more invasive treatments.

    A 57-year-old woman experienced bilateral acute ischemic optic neuropathy after spine surgery. Routine MR imaging sequence, T2-weighted image, showed subtle high signal intensity on bilateral optic nerves. A contrast-enhanced T1 weighted image showed enhancement along the bilateral optic nerve sheath. Moreover, diffusion-weighted image (DWI) and an apparent diffusion coefficient map showed markedly restricted diffusion on bilateral optic nerves. Although MR findings of T2-weighted and contrast enhanced T1-weighted images may be nonspecific, the DWI finding of cytotoxic edema of bilateral optic nerves will be helpful for the diagnosis of acute ischemic optic neuropathy after spine surgery.

    The purpose of this construction is the improvement of heat transfer in finned tube heat exchangers, and therefore the improvement of its efficiency or its output per unit volume. This is achieved by preventing the formation of flow boundary layers in gaseous fluid. This effect always occurs on flow of smooth adjacent laminae, and especially if these have pipes carrying liquid passing through them; it worsens the heat transfer of such a boundary layer considerably compared to that in the turbulent range. The fins, which have several rows of heat exchange tubes passing through them, are fixed at a small spacing on theses tubes. The fins have slots cut in them by pressing or punching, where the pressed-out material remains as a web, which runs parallel to the level of the fin and at a small distance from it. These webs and slots are arranged radially around every tube hole, e.g. 6 in number. For a suitable small tube spacing, two adjacent tubes opposite each other have one common slot. Many variants of such slot arrangements are illustrated.

    Overview From a technical perspective, CMS has been in “beam operation” state since 6th November. The detector is fully closed with all components operational and the magnetic field is normally at the nominal 3.8T. The UXC cavern is normally closed with the radiation veto set. Access to UXC is now only possible during downtimes of LHC. Such accesses must be carefully planned, documented and carried out in agreement with CMS Technical Coordination, Experimental Area Management, LHC programme coordination and the CCC. Material flow in and out of UXC is now strictly controlled. Access to USC remains possible at any time, although, for safety reasons, it is necessary to register with the shift crew in the control room before going down.It is obligatory for all material leaving UXC to pass through the underground buffer zone for RP scanning, database entry and appropriate labeling for traceability.

Overview of the extended Technical Stop  The principal objectives of the extended Technical Stop affecting the detector itself were the installation of the TOTEM T1 telescopes on both ends, the readjustment of the alignment link-disk in YE-2, the replacement of the light-guide sleeves for all PMs of both HFs, and some repairs on TOTEM T2 and CASTOR. The most significant tasks were, however, concentrated on the supporting infrastructure. A detailed line-by-line leak search was performed in the C6F14 cooling system of the Tracker, followed by the installation of variable-frequency drives on the pump motors of the SS1 and SS2 tracker cooling plants to reduce pressure transients during start-up. In the electrical system, larger harmonic filters were installed in ...

    Full Text Available Context: Anatomical localization of pituitary adenoma can be challenging in adrenocorticotropic hormone (ACTH-dependent Cushing's syndrome, and bilateral inferior petrosal sinus sampling (BIPSS is considered gold standard in this regard. Stimulation using corticotrophin-releasing hormone (CRH improves the sensitivity of BIPSS, however, same is not easily available in India. Therefore, we undertook this study of BIPPS using vasopressin as agent for stimulation owing to its ability to stimulate V3 receptors present on corticotrophs. Aims: To study the tumor localization and lateralization in difficult to localize cases of ACTH-dependent Cushing's syndrome by bilateral inferior petrosal sinus sampling using vasopressin for corticotroph stimulation. Settings and Design: Prospective observational study. Subjects and Methods: Six patients (5 females meeting inclusion criteria underwent BIPSS using vasopressin for stimulation. Results: All six patients had nonsuppressible overnight and low dose dexamethasone suppression test with elevated plasma ACTH levels suggestive of ACTH-dependent Cushing's syndrome. High dose dexamethasone suppression test showed suppressible cortisol in two cases, and microadenoma was seen in two patients on magnetic resonance imaging pituitary. Contrast enhanced computed tomography of the abdomen showed left adrenal hyperplasia in one case and anterior mediastinal mass with bilateral adrenal hyperplasia another. Using BIPSS four patients were classified as having Cushing's disease that was confirmed histopathologically following surgery. Of the remaining two, one had primary pigmented nodular adrenocortical disease, and another had thymic carcinoid with ectopic ACTH production as the cause of Cushing's syndrome. No serious adverse events were noted. Conclusions: Vasopressin may be used instead of CRH and desmopressin for stimulation in BIPSS.

  18. Idiopathic Bilateral External Jugular Vein Thrombosis.

    Science.gov (United States)

    Hindi, Zakaria; Fadhel, Ehab

    2015-08-20

    Vein thrombosis is mainly determined by 3 factors, which constitute a triad called Virchow's triad: hypercoagulability, stasis, and endothelial injury. Venous thrombosis commonly occurs in the lower extremities since most of the blood resides there and flows against gravity. The veins of the lower extremities are dependent on intact valves and fully functional leg muscles. However, in case of valvular incompetency or muscular weakness, thrombosis and blood stasis will occur as a result. In contrast, the veins of the neck, specially the jugulars, have distensible walls which allow flexibility during respiration. In addition, the blood directly flows downward towards the heart. Nevertheless, many case reports mentioned the thrombosis of internal jugular veins and external jugular veins with identified risk factors. Jugular vein thrombosis has previously been associated in the literature with a variety of medical conditions, including malignancy. This report is of a case of idiopathic bilateral external jugular vein thrombosis in a 21 year-old male construction worker of Southeast Asian origin with no previous medical history who presented with bilateral facial puffiness of gradual onset over 1 month. Doppler ultrasound and computed tomography were used in the diagnosis. Further work-up showed no evidence of infection or neoplasia. The patient was eventually discharged on warfarin. The patient was assessed after 6 months and his symptoms had resolved completely. Bilateral idiopathic external jugular veins thrombosis is extremely rare and can be an indicator of early malignancy or hidden infection. While previous reports in the literature have associated jugular vein thrombosis with malignancy, the present case shows that external jugular vein thrombosis can also be found in persons without malignancy.

    1981-01-01

    A new method for measuring the depth of the parasternal lymph node was studied. The bilateral collimator used in this study consisted of two arrays of parallel holes which were slanted at +-30 degrees, respectively, to the vertical line. When the collimator was set to image the object in both sides of the field, the object and the dual images formed a regular triangle. The distance (D) from the image (crystal) plane to the object can be expressed by the equation: D = 1/2.L.cot30 0 = 0.866.L where L is the interval between the dual images calibrated to the real length. The distance from the collimator surface to the object is obtained by subtracting the effective thickness (T) between the image plane and the collimator surface from D. T was experimentally measured by the above equation, placing point sources on the collimator surface. The principle was applied to measure the depth of the parasternal lymph node. The parasternal lymphoscintigram was obtained four hours after bilateral subcostal injection of sup(99m)Tc-sulfur colloid and the image was taken by a Searle Pho/Gamma LFOV camera equipped with the bilateral collimator. When the scintigraphic image was made, radioactive markers were placed at the body surface to measure the distance from the collimator surface to the body surface Nineteen patients were examined. As a result, the lymph nodes were found to be located in the depths ranging widely from 0.4 to 6.5 cm from the anterior surface of the chest wall. These lymph nodes were thought to contain the deeply seated mediastinal nodes, and the superficial nodes located directly beneath the skin. Model studies were also performed to estimate the accuracy of this method and satisfactory results were obtained. (author)

  20. Bilateral first rib fractures: A case report

    Full Text Available From the time first rib fractures were first described in 1869, they have been a source of anxiety to attendant trauma surgeons working in the accident and emergency department of major hospitals. First rib fractures are associated with major thoracic trauma and may involve injury to subclavian vessels, brachial plexus, and mediastinal structures. But these complications are more often seen following unilateral first rib fractures. In contrast, bilateral first rib fractures may follow insignificant trauma, suggesting a different mechanism involved. Serious vascular injuries and brachial plexus injuries are rare and angiograms for evaluation of these patients aren′t routinely warranted. The case that we report illustrates this very point.

    Full Text Available Orthodontic treatment aims to improve esthetics, function and structural balance. In some rare circumstances, the clinician may not be able to achieve the ideal treatment goals because of complex multiple orthodontic problems, which may include significant mutilation of the dentition. Brodie bite, a complete buccal posterior crossbite is a problem, which confronts clinicians with often complex variable etiology. The following case report demonstrates treatment of bilateral buccal nonocclusion that is mainly due to a maxillary dental arch issue rather than mandibular retrognathism.

    Primary amenorrhea is a common problem. Diagnosis is usually by going through systematic approach of history, examination and investigations. This case had bilateral large endometriotic cysts in the adnexal region. Uterus was normal sized with well-formed endometrium. She underwent laparotomy followed by drainage of endometriotic cysts, stripping and reconstruction of ovaries was performed. Patient was given a trial of combined oral contraceptive pills for two consecutive cycles to observe withdrawal bleeding, but it failed. Till now we are unable to find out such case in literature. Exact case of primary amenorrhea could not be found. (author)

    2011-09-01

    Acupuncture is becoming increasingly popular in the United States for a wide variety of uses, ranging from the treatment of chronic back pain to aiding in addiction therapy. As this form of complementary and alternative medicine becomes more prevalent in certain areas of the country, it is of paramount importance that the emergency physician be familiar with its methods and potential complications. In general, acupuncture is perceived as fairly safe. However, it is not without risks or side effects. In this case report, we discuss the history, methods, and common complications of acupuncture in the context of a patient who presented to the Emergency Department (ED) with bilateral pneumothoraces secondary to acupuncture therapy.

    This report describes the third case of a true bilateral Juvenile nasopharyngeal angiofibroma (JNA), i.e. two separate JNA arising from both sides simultaneously. The associated multiple recurrences in such a case have not yet been reported. A 21-year-man underwent transpalatal excision and recurred twice. The last 'neo-occurrence' encountered after 2 years was at a different site and was subsequently managed by post-embolization endoscopic resection. A complete report of its clinico-radiological features and management outcome is discussed.

    Wallis, Kate E; Blum, Nathan J; Waryasz, Stephanie A; Augustyn, Marilyn

    Sonia is a 4 years 1 month-year-old girl with Waardenburg syndrome and bilateral sensorineural hearing loss who had bilateral cochlear implants at 2 years 7 months years of age. She is referred to Developmental-Behavioral Pediatrics by her speech/language pathologist because of concerns that her language skills are not progressing as expected after the cochlear implant. At the time of the implant, she communicated using approximately 20 signs and 1 spoken word (mama). At the time of the evaluation (18 months after the implant) she had approximately 70 spoken words (English and Spanish) and innumerable signs that she used to communicate. She could follow 1-step directions in English but had more difficulty after 2-step directions.Sonia was born in Puerto Rico at 40 weeks gestation after an uncomplicated pregnancy. She failed her newborn hearing test and was given hearing aids that did not seem to help.At age 2 years, Sonia, her mother, and younger sister moved to the United States where she was diagnosed with bilateral severe-to-profound hearing loss. Genetic testing led to a diagnosis of Waardenburg syndrome (group of genetic conditions that can cause hearing loss and changes in coloring [pigmentation] of the hair, skin, and eyes). She received bilateral cochlear implants 6 months later.Sonia's mother is primarily Spanish-speaking and mostly communicates with her in Spanish or with gestures but has recently begun to learn American Sign Language (ASL). In a preschool program at a specialized school for the deaf, Sonia is learning both English and ASL. Sonia seems to prefer to use ASL to communicate.Sonia receives speech and language therapy (SLT) 3 times per week (90 minutes total) individually in school and once per week within a group. She is also receiving outpatient SLT once per week. Therapy sessions are completed in English, with the aid of an ASL interpreter. Sonia's language scores remain low, with her receptive skills in the first percentile, and her

    Asymptomatic idiopathic condylar resorption is a rare disease of difficult diagnosis and treatment. We review the literature about this rare condition and report a case of a patient, affected by Down syndrome, who underwent a complete untreated bilateral condylar resorption in adolescence and then developed pain on chewing only 20 years later. Despite a precise orthodontic and surgical therapeutic plan, treatment had to be discontinued because of patient lack of compliance. This case is the first of its kind to be reported and emphasizes the need for special attention in patients with disability.

    Full Text Available We study a mathematical problem describing the frictionless adhesive contact between a viscoelastic material with damage and a foundation. The adhesion process is modeled by a bonding field on the contact surface. The contact is bilateral and the tangential shear due to the bonding field is included. We establish a variational formulation for the problem and prove the existence and uniqueness of the solution. The existence of a unique weak solution for the problem is established using arguments of nonlinear evolution equations with monotone operators, a classical existence and uniqueness result for parabolic inequalities, and Banach's fixed point theorem.

    Full Text Available Keisho Hirota1,2, Masayuki Akimoto1,3, Toshiaki Katsura21Department of Ophthalmology, Kyoto Medical Center, National Hospital Organization, 2Internal Medicine, Kyoto Medical Center, 3Clinical Research Center, Kyoto Medical Center, Kyoto, JapanPurpose: The report of a case of bilateral acute retinal necrosis after herpetic meningitis.Case report: A 47-year-old man was admitted with the chief complaint of persistent high fever and transient loss of consciousness. Although his general condition improved after intravenous acyclovir administration, the patient presented with visual loss in both eyes 4 days after admission. Visual acuity in his right eye was 20/200 and his left eye had light perception alone. Both eyes showed panretinal arteritis diagnosed as acute retinal necrosis. Panretinal photocoagulation was performed for both eyes. Progression of retinal detachment was prevented in both eyes; however, visual acuity of the left eye was totally lost because of neovascular glaucoma. Visual acuity of the right eye recovered to 20/20.Conclusion: Although cases of bilateral acute retinal necrosis have been reported after herpetic encephalitis, this condition is rare after herpetic meningitis. Prophylactic acyclovir therapy and early panretinal photocoagulation may prevent retinal detachment and improve the prognosis. Neurologists and ophthalmologists should be aware that not only herpetic encephalitis but also herpetic meningitis can lead to acute retinal necrosis within a very short interval.Keywords: acute retinal necrosis, herpetic meningitis, herpes simplex, varicella zoster virus

    Full Text Available To present a rare complication, such as bilateral cataracts, in a man who sustained a high-voltage electrical injury. A 35- year-old man was admitted with a complaint of decrease in visual acuity. He had a history of a contact with a power line carrying 30.000 volts of electricity while working at a construction site. Examination at a burn center revealed second-degree facial, neck and left foot burns. One month later, the patient underwent amputation of fourth and fifth toes of his left foot. During the next 6 months, he noted decreasing vision in both eyes. Ocular examination 1 year after the accident revealed that the patient’s visual acuity had deteriorated to 1/10 in both eyes. The cornea on the left eye showed superficial punctate opacities. The lenses in both eyes had anterior subcapsular cortical lens opacities and posterior subcapsular opacities. Uncomplicated bilateral phacoemulsification surgery with intraocular lens implantation was performed and the patient’s visual acuity returned to 10/10 in both eyes. We noted that the fundus remained normal in both eyes. Electrical cataracts are still a serious potential complication that may occur after electrical injury. Awareness of this by burn team members is important for providing optimal treatment to those who have suffered an electrical injury. (Turk J Ophthalmol 2011; 41: 197-9

    2014-02-01

    This case report describes an unexpected event that took place as a result of using improvised equipment. The patient, a 16-year-old female undergoing complex oral surgery, suffered bilateral pneumothorax following the improper use of an airway support device. During the immediate postoperative period with the patient still intubated, oxygen tubing was attached to a right angle elbow connector with the port closed and 10 L/minute oxygen flow was administered to the patient in a manner that did not allow the patient to exhale. Within seconds, pneumothorax was apparent as the patient's vital signs deteriorated, visible swelling was noted in the shoulders and neck, and there was an absence of breath sounds on auscultation. This case study has application beyond the immediate discussion of bilateral pneumothorax, serving as a caution about the unintended consequences of equipment improvisation. In addition to highlighting the hazards of providing patient care with a non-standard device, this study also provides a powerful example of the human factors that can contribute to medical errors in the healthcare setting.

  15. Bilateral parotid gland tuberculosis: A rare occurrence

    Directory of Open Access Journals (Sweden)

    Rajendra Takhar

    2015-07-01

    Full Text Available Parotid gland tuberculosis is an extremely rare form of extrapulmonary tuberculosis, even in countries where tuberculosis is endemic like India; however, it should be included as one of the differentials of discrete parotid swelling as it generally presents as a slow-growing mass indistinguishable from a malignancy and even imaging too, can’t differentiate these clearly. The majority of the previously reported cases were mostly unilateral and diagnosed by histopathological examination of post parotidectomy specimens. Here we are describing a case of tuberculosis of both parotid glands in a 25 year-old male who was referred to us with bilateral parotid region swelling of two month duration. Tubercular parotiditis was confirmed by demonstration of epithelioid granuloma and caseous necrosis compatible with TB on fine needle aspiration cytology (FNAC. He was treated with four drug anti-TB regimen (2HERZ + 4HR leading to full recovery and complete disappearance of swelling and symptoms with no recurrence till one year of follow up. Apart from rarity due to bilateral involvement, this case report highlights the clinical presentation, ultrasonography and other imaging findings, and significance of FNAC in diagnosis of this uncommon entity reinforcing the fact that the diagnosis of parotid gland tuberculosis requires a high degree of clinical suspicion.

    Full Text Available We report the occurrence of a bilateral pneumothoraces after unilateral central venous catheterization of the right subclavian vein in a 70-year-old patient. The patient had no history of pulmonary or pleural disease and no history of cardiothoracic surgery. Two days earlier, she had a median laparotomy under general and epidural anaesthesia. Prior to the procedure, the patient was hemodynamically stable and her transcutaneous oxygen saturation was 97% in room air. We punctured the right pleural space before cannulation of the right subclavian vein. After the procedure, the patient slowly became hemodynamically instable with respiratory distress. A chest radiograph revealed a complete left-side pneumothorax and a mild right-side pneumothorax. The right-side pneumothorax became under tension after left chest tube insertion. The symptoms finally resolved after insertion of a right chest tube. After a diagnostic work-up, we suspect a congenital “Buffalo chests” explaining bilateral pneumothoraces and a secondary tension pneumothorax.

    The Bilateral filter is able to get a lower noise level while retaining the edges in images. The downside of a bilateral filter is the high order of the problem itself. While having a Volume size of N with a dimension of d and a filter window of r the problem is of size N{sup d} . r{sup d}. In the literature there are some proposals for speeding up by reducing this order by approximating a component of the filter. This leads to inaccurate results which often implies non acceptable artifacts for medical imaging. A better way for medical imaging is to speed up the filter itself while leaving the basic structure intact. This is the way our implementation uses. We solve the problem of calculating the function of e{sup -x} in an efficient way on modern architectures, and the problem of vectorizing the filtering process. As result we implemented a filter which is 2.5 times faster than the highly optimized basic approach. By comparing the basic analytical approach with the final algorithm, the differences in quality of the computing process is negligible to the human eye. We are able to process a volume with 512{sup 3} voxels with a filter of 25 x 25 x 1 in 21 s on a modern Intel Xeon platform with two X5590 processors running at 3.33 GHz. (orig.)

    Cervical spondylolysis, which is defined as a cleft between the superior and inferior articular facets of the articular pillar, is a rare condition. The sixth cervical vertebra (C6) is the level most commonly affected. Cases involving C2, C3, C4, or C5 have also been reported. However, to date, no case of C7 spondylolysis has been reported. To present a rare case of bilateral spondylolysis of the seventh cervical vertebra (C7) in a 58-year-old man. A case report. A 58-year-old man visited our hospital with chronic posterior neck pain radiating to the left upper extremity. Magnetic resonance imaging (MRI) study revealed left foraminal disc herniations at C5-C6 and C6-C7. Cervical spondylolysis involving C7 was discovered incidentally during computed tomography (CT)-guided transforaminal steroid injection. Plain radiographs, CT images, and MRIs were reviewed thoroughly once again. The patient's symptoms were relieved after he received CT-guided transforaminal steroid injections. Plain radiographs revealed a radiolucent defect in the articular pillar and cleft at the spinous process of C7. Computed tomography confirmed bilateral spondylolysis and spina bifida occulta of the C7 vertebra. Magnetic resonance imaging revealed absence of edema, which was suggestive of a chronic lesion. Involvement of C7 is not exceptional in a case of cervical spondylolysis. Copyright © 2010 Elsevier Inc. All rights reserved.

  20. Improving efficiency in bilateral emission trading

    Burtraw, D.; Harrison, K.W.; Turner, P.

    1998-01-01

    When environmental damages from emissions are spatially nonuniform, permit trading has been modeled most often as a 'pollution offset program' in which emission permits are traded between agents, subject to constraints on ambient air quality. To date the institution envisioned to implement such a program involves trading on a bilateral and sequential basis. However, simulation studies indicate that the sequence of trades may alter the outcome and undermine the cost savings from a pollution offset program. This paper identifies a design for the trading institution that tends to overcome this phenomenon and improve the efficiency of equilibria obtained in a simulation model. We model a bilateral trading process for the reduction of sulfur dioxide emissions with a stochastic description of the sequence of trades within groups of nations in Europe. When trading takes place between disaggregated, stylistic representations of economic enterprises, rather than between national governments, a significantly greater portion of potential savings is achieved. In fact, under most sets of assumptions, approximate first order stochastic dominance is achieved wherein the more decentralized the trading agents, the greater the expected savings from a trading program. 4 figs., 2 tabs., 31 refs

    Full Text Available A 48-year-old woman sustained simultaneous isolated bilateral greater trochanteric fracture, following a road traffic accident. The patient presented to us 1 month after the injury. She presented with complaints of pain in the left hip and inability to walk. Roentgenograms revealed displaced comminuted bilateral greater trochanter fractures. The fracture of the left greater trochanter was reduced and fixed internally using the tension band wiring technique. The greater trochanter fracture on the right side was asymptomatic and was managed conservatively. The patient regained full range of motion and use of her hips after a postoperative follow-up of 6 months. Isolated fractures of the greater trochanter are unusual injuries. Because of their relative rarity and the unsettled controversy regarding their etiology and pathogenesis, several methods of treatment have been advocated. Furthermore, the reports of this particular type of injury are not plentiful and the average textbook coverage afforded to this entity is limited. In our study we discuss the mechanism of injury and the various treatment options available.

    1990-01-01

    The diagnostic strategy for asymptomatic patients with persistent bilateral bilar adenopathy often involves invasive procedures. The authors used Bayesian analysis to: (1) estimate the relative prevalences of diseases causing bilateral bilar adenopathy; (2) assess changes in the prevalence of disease by race, the presence of other clinical symptoms, and geography; and (3) determine the value of relevant noninvasive tests, including the angiotensin-converting enzyme (ACE) assay, gallium scan, and purified protein derivative (PPD), in order to assess when a strategy of watchful waiting is appropriate. The analysis indicated that the ACE assay, particularly when paired with the PPD, can identify many patients who might safely be managed without immediate invasive biopsy. Patients who are ACE+ and PPD- have an estimated probability of sarcoidosis of 0.95 or greater; patients who are ACE- and PPD+ have a probability of tuberculosis of 0.86 if black, 0.79 if white. In contrast, gallium scanning has no diagnostic role in this clinical situation. Bronchoscopic or mediastinoscopic biopsy has a limited role for patients who are ACE+ PPD- or ACE- PPD+ because of limited sensitivity. Patients who are both ACE- and PPD-, particularly if white, may have a high enough risk of lymphoma to consider invasive biopsy

  3. Medical tourism: a review of the literature and analysis of a role for bi-lateral trade.

    Smith, Richard; Martínez Álvarez, Melisa; Chanda, Rupa

    2011-12-01

    With increasing globalization, many countries are considering opening their health systems to greater cross-border movement of patients. This is usually done from the viewpoint of a multi-lateral trade relationship. This paper considers the issues that arise from this debate from a bi-lateral perspective. A systematic literature review was carried out on 'Medical Tourism' from the perspective of a bi-lateral trade relationship, using the UK and India as a case study. There is a dearth of data and discussion on such bi-lateral trade. This limited evidence offers some suggestions. Exporting countries may benefit from medical tourism by generating foreign exchange and reversing the brain drain, but run the risk of creating a dual system, where the local population is crowded out. Importing countries can benefit from alleviating waiting lists and lowering healthcare costs, but may risk quality of care and legal liability. However, evidence from a bi-lateral perspective suggests that the positive aspects can be capitalised, and the negative ones reduced. The key recommendations from this paper are for more evidence to be collected at the country and international level, and for countries to consider trade in health services from a bi-lateral rather than multi-lateral perspective.

    Full Text Available Background. The risk of ovarian cancer is increased in the association of ovarian tumor, ascites, and hydrothorax with the significant elevated tumor marker CA-125. However, this association can be observed in a rare clinical and benign pathological entity, that is Demons-Meigs’ syndrome. Objective. To describe a rare case of Demons-Meigs' syndrome observed in our department. Methods. A black African woman of 35 years old, seventh gravida and fourth parous, underwent a total abdominal hysterectomy with bilateral salpingoophorectomy for large bilateral ovarian masses associated with significant ascites, bilateral pleural effusion, and particular highly elevated tumor marker CA-125 (1835 UI/mL in a pronounced general alteration condition. Results. The postoperative course was uneventful characterized by a complete remission of hydrothorax and ascites with normal level of CA-125 three months after tumor excision. Histology of both masses revealed a bilateral ovarian fibrothecoma, a benign tumor of the ovary, thus confirming the diagnosis of Demons-Meigs’ syndrome. Conclusion. The Demons-Meigs syndrome, although it strongly mimics the clinical picture of malignant metastatic ovarian cancer, remains a disease with benign prognosis after surgical tumor resection. This is a rare condition that must be known and recognized by practitioners to avoid unnecessary practices.

    2017-09-01

    Conclusion:. Surgical outcomes of bilateral reconstructions in patients with abdominal scars are generally comparable with ones in patients without prior surgery; however, some problems have been identified. These procedures might have some intraoperative considerations and often require increased operative times. Apart from the traditional preoperative computed tomography angiography, intraoperative imaging (e.g., fluorescence angiography may be advocated in patients with abdominal scars.

    For the reporting period, the CMS common systems and infrastructure worked well, without failures that caused significant data losses. One more disconnection of the magnet cold box occurred in the shadow of interruptions in data taking, caused by a series of technical faults. The recognition during 2012 that re-connection can only safely be done at around 2 T implies a minimum magnet recovery time of 12 hours and raises serious concerns about the number of ramping cycles of the magnet these incidents cause. This has triggered studies of how to make the cryo-system of the magnet more robust against failures. The proton-proton run ended just before the end-of-year CERN closure, during which CASTOR was installed on the negative end of CMS and both ZDC calorimeters were installed in TAN absorbers the LHC tunnel, in preparation for the heavy-ion run. The installation of CASTOR was an excellent “engineering test” of procedures for working in an activated environment. Despite some technical pr...

CMS is closed, in very close to the ideal low luminosity configuration, and performed well in the first tests with LHC beam. Behind this encouraging news is the story of a summer of intense commitment by many teams (from the collaboration and 3 CERN departments) working together, against the clock and despite many minor setbacks, to ensure that the experiment was ready to play a leading role in the excitement of September 10. Following beampipe bakeout and refill with pure neon, a magnificent effort by the ECAL group and the pt 5 technical crew made it possible to install and commission all 4 ECAL endcap Dees before the end of August. In the shadow of this activity, the barrel and forward pixel trackers and part of the beam monitoring were installed within the vac tank. The pt 5 technical teams then succeeded in safely removing the 20t installation tables and their support blocks from beneath the already installed ...

      Operational experience 2011 CMS is approaching the end of a very successful year of operation. Proton- proton running ended in the late afternoon of 30th October with a stunning 5.73 fb–1 delivered by LHC, of which CMS recorded 5.22 fb–1. During heavy-ion operation, which continues until 7th December, both the accelerator and the CMS detector have also performed very well. Despite the encouraging overall reliability of technical operation, several infrastructure failures which occurred since the last Bulletin are worthy of mention, with one leading for the first time to significant data-loss. On 10th July, a CERN-wide power failure brought down essentially all services including the magnet, due to an MCS setting being left in “manual” after the recent technical stop, but there was no significant damage and the detector was operational before the LHC, despite a slow and tortuous recovery (one of several indications this year that there is room for improve...

    Recurrence of hypercortisolism in patients after bilateral adrenalectomy for Cushing disease is extremely rare. We present a 27-year-old man who previously underwent bilateral adrenalectomy for Cushing disease with complete clinical resolution. Cushingoid features recurred 12 years later, with bilateral testicular enlargement. Hormonal tests confirmed adrenocorticotropic hormone (ACTH)-dependent Cushing disease. Surgical resection of the testicular tumors led to clinical and biochemical remission. Gene expression analysis of the tumor tissue by quantitative polymerase chain reaction showed high expression of all key steroidogenic enzymes. Adrenocortical-specific genes were 5.1 × 105 (CYP11B1), 1.8 × 102 (CYP11B2), and 6.3 × 104 (MC2R) times higher than nonsteroidogenic fibroblast control. This correlated with urine steroid metabolome profiling showing 2 fivefold increases in the excretion of the metabolites of 11-deoxycortisol, 21-deoxycortisol, and total glucocorticoids. Leydig-specific genes were 4.3 × 101 (LHCGR) and 9.3 × 100 (HSD17B3) times higher than control, and urinary steroid profiling showed twofold increased excretion of the major androgen metabolites androsterone and etiocholanolone. These distinctly increased steroid metabolites were suppressed by dexamethasone but unresponsive to human chorionic gonadotropin stimulation, supporting the role of ACTH, but not luteinizing hormone, in regulating tumor-specific steroid excess. We report bilateral testicular tumors occurring in a patient with recurrent Cushing disease 12 years after bilateral adrenalectomy. Using mRNA expression analysis and steroid metabolome profiling, the tumors demonstrated both adrenocortical and gonadal steroidogenic properties, similar to testicular adrenal rest tumors found in patients with congenital adrenal hyperplasia, suggesting the presence of pluripotent cells even in patients without congenital adrenal hyperplasia.

    An analysis of the present sealing system in the H 2 S compressors showed that the risk of accidental hydrogen sulfide escape into the atmosphere is high in case of a seal oil pressure loss. At the same time there exist drawbacks occurring even in normal regime of functioning among which one can mention: - relatively high losses of oil occur, part of the oil being carried away by the compressors and released into the isotopic exchange columns where the water counter current flow produces a foaming that reduces the column processing capacity; - part of the sealing oil leaks reaches the final product, the heavy water, where from it must be removed by chemical procedures; - the installations adjacent to the sealing system are relatively sophisticated and require relatively high expenses for exploitation and maintenance. The classical sealing systems using sealing rings, sleeves, labyrinths, etc, cannot be used since their safe working range is exceeded due to either driving shaft rotational speed, or to the increase of its diameter, or else to an increase of the speed of motion of moving parts relative to the fix parts. The sealing systems with magnetic liquids are rather sophisticated and expensive while in case of electric supply loss they are completely unsafe, because their sealing capacity vanishes. The materials used for sealing gaskets limit their application only to the cases when the relative motion of the moving pieces is low or vanishing what happens only at shut down or failure situations. To prevent these drawbacks of the present seal system in the H 2 S compressors of the isotopic exchange columns and having in view the limitations of the currently used sealing systems a new system of sealing was conceived and designed on the basis of the patent titled 'Sealing Installation and Procedure' recorded by OSIM under No. A/0315/10.04.2003. The new system can be built as a single or double stage each of them having in turn a dynamic and a static sub-stage. The

    Full Text Available Introduction. Pathological dislocation of the hip is one of the most severe complications of acute hematogenous osteomyelitis. The program of treatment for children with pathological hip dislocation is complex, but it has been sufficiently developed and implemented very successfully. At the same time, the available literature provides no cases of treating children with bilateral pathological hip dislocations after hematogenous osteomyelitis. There is no information on the incidence of such cases or in regards to remote functional results. Materials and methods. The results of the treatment of 18 children with bilateral pathological dislocation of the hip after hematogenous osteomyelitis are presented, which constituted 23.1% of the total number of patients (78 who underwent surgery in 2000–2016 for the diagnosis of pathological hip dislocation. Both hip joints were surgically operated on in 12 patients, while one hip joint was operated on in 6 patients. To assess the anatomical and functional state of hip joints, the clinical and roentgenological diagnostic techniques were used. Results and discussion. To stabilize and restore the function of the hip joints, 18 children underwent 30 surgical interventions: simple open hip reduction (19 and open hip reduction with hip arthroplasty with one (6 or two (5 demineralized osteochondral allogeneic grafts. The decision regarding the possibility of performing surgical intervention on the second hip joint was made only after a child's check-up examination was complete and after positive information about the anatomical and functional state of the operated hip joint was obtained. According to these criteria, 14 (77.8% children underwent surgical treatment of the second hip joint 1–1.5 years after the course of conservative measures to restore the range of motion in the previously operated hip joint. Over a period of 1–12 years, 17 patients were examined, 10 of which underwent an operation on both

    Bilateral gamma process is widely used in risk management and asset pricing. However the behavioral implications of this process remain unknown. This paper investigates this problem for the first time within the framework of Tauchen and Pitts (1983). With the assumption that there are two types of traders in the market, the optimistic and the pessimistic, we find the bilateral gamma process can be derived from Walrasian equilibrium. This finding establishes the microstructure foundations for the bilateral gamma process.

    Overview Once again, the bulk of this article reviews the intense activity of a recently completed shutdown, which, although quite unforeseeable until a few weeks before it started, proved by its success that our often advertised capability to conduct major maintenance within a two month period is real. Although safely completed, on-time to remarkable precision, the activity was not without incident, and highlighted our dependence on many experienced, specialist teams and their precise choreography. Even after the yoke was safely closed, magnet re-commissioning and beampipe pumpdown showed new and thought-provoking behaviour. The struggle to maintain adequate technical resources will be a pre-occupation over the coming months, in parallel with the start of truly sustained operation, for which various procedures are still being put in place. Planning for future shutdowns must now become a high priority, with many working groups and task forces already in existence to prepare infrastructure improvements and to...

    1978-11-01

    The memory loss associated with bilateral and nondominant unilateral ECT was assessed with verbal memory tests known to be sensitive to left temporal lobe dysfunction and with nonverbal memory tests known to be sensitive to right temporal lobe dysfunction. Bilateral ECT markedly impaired delayed retention of verbal and nonverbal material. Right unilateral ECT impaired delayed retention of nonverbal material without measurably affecting retention of verbal material. Nonverbal memory was affected less by right unilateral ECT than by bilateral ECT. These findings, taken together with a consideration of the clinical efficacy of the two types of treatment, make what appears to be a conclusive case for unilateral over bilateral ECT.

    Sildenafil citrate (Viagra) is one of the frequently prescribed drugs for men with erectile dysfunction. We describe a 52-year-old man with bilateral middle cerebral artery (MCA) territory infarction after sildenafil use. He ingested 100 mg of sildenafil and about 1 h later, he complained of chest discomfort, palpitation and dizziness followed by mental obtundation, global aphasia and left hemiparesis. Brain magnetic resonance imaging documented acute bilateral hemispheric infarction, and cerebral angiography showed occluded bilateral MCA. Despite significant bilateral MCA stenosis and cerebral infarction, systemic hypotension persisted for a day. We presume that cerebral infarction was caused by cardioembolism with sildenafil use.

Here, we report a case with bilateral MMI caused by nondominant vertebral artery occlusion confirmed by brain digital subtraction angiography and magnetic resonance imaging basi-parallel-anatomical-scanning. We highlight that anterior spinal arteries could originate from a unilateral vertebral artery (VA). Radiologists and neurologists should pay attention to the nondominant VA as bilateral MMI may be induced by occlusion of nondominant VA that supplies the bilateral anteromedial territories of the medulla.

    Full Text Available X-linked juvenile retinoschisis is a rare hereditary retinal disease characterized by a tangential splitting of the neurosensory retina which may cause early-onset visual impairment. Existence of the retinal neurosensory layer splitting on cross-sectional images of optical coherance tomography (OCT and the absence of leakage on fluorescein angiography (FA help confirming the diagnosis. Such diagnostic tests are also helpful in determining the management of the disease. However, most of the retinoschisis cavities remain stable and rarely extend to the posterior pole, many authors suggest laser prophylaxis to avoid the potential risk of retinal detachment due to holes in the outer retinal layer. Herein, we report a case with bilateral foveal retinoschisis accompanying unilateral peripheral retinoschisis who was evaluated with detailed ophthalmologic examination. Visual acuity, fundoscopy, OCT, and FA remained stable in the second year of follow-up after prophylactic argon laser treatment.

    Full Text Available Idiopathic granulomatous mastitis (IGM is an uncommon benign disorder of the breast. At clinical examination, IGM is characterized by an inflammatory process of the breast, usually unilateral. Possible clinical findings are palpable mass with erythematous skin, pain, sterile abscesses, fistula and nipple retraction. Mammography and ultrasound findings are not specific for IGM. Magnetic resonance imaging (MRI is a useful tool for the differential diagnosis; it is also necessary to delineate the exact extension of the disease and to plan the correct treatment. Final diagnosis is histological. We described an unusual case of IGM with bilateral involvement in a patient with history of pacemaker implantation and IGM typical clinical symptoms. Mammography, ultrasound, and MRI examinations were performed to identify the inflammatory disorder and to plan the correct therapy. Imaging features were correlated with final histological diagnosis of IGM.

The aim is to establish guidelines for the management of this disorder that is so rare. a 75-year-old with tumors in both breasts, which were completely resected with removal of palpable nodes. The histopathological study reported ductal carcinoma. The indicated treatment was adjuvant tamoxifen and radiotherapy. The patient is currently in a disease-free period. this is a rare disease, whose main treatment is surgery, hence the importance of early diagnosis. Most cases require adjuvant chemotherapy and radiotherapy because they are usually diagnosed at an advanced stage.

    INTRODUCTION Gorlin syndrome (GS), also known as nevoid basal cell carcinoma syndrome (NBCCS), is a rare hereditary, autosomal dominant disease that affects various systems. Its prevalence is estimated at 1/57,000 to 1/256,000 of the population. It is characterized by basal cell carcinomas, multiple odontogenic keratocysts, skeletal abnormalities and ovarian fibroma, among other disorders. PRESENTATION OF CASE To report the case of a young patient with Gorlin syndrome and bilateral ovarian fibroma. DISCUSSION A 20-year old patient with Gorlin syndrome presented with facial asymmetry, broad nasal root, dental abnormalities, micrognathism, convergent strabismus, multiple pigmented lesions on the trunk and face, pectus excavatum, kyphoscoliosis and a palpable mass in the abdomen occupying the entire pelvic region. CONCLUSION Gorlin–Goltz syndrome is a hereditary pathology that includes numerous clinical manifestations. Diagnosis is clinical and genetic confirmation is unnecessary. PMID:22771908

    Emphysematous pyelonephritis (EPN) is a serious infectious disease that occurs more frequently in diabetic patients. Radiological studies are indispensable for distinguishing between the two types since each is associated with a markedly different prognosis. We present a case of bilateral EPN diagnosed as type I on the basis of computed tomography findings, differentiating it from type II EPN, taking into account the prognostic value of this distinction. Type I EPN is characterized by the destruction of the renal parenchyma, a mottled or linear gas pattern and the absence of renal and perirenal fluid collection. Type II EPN is characterized by a loculated or bubbly gas pattern, the existence of fluid collection and less marked renal destruction. Type I is more aggressive and is associated with high rate of mortality. (Author) 7 refs

  11. Virtual water trade and bilateral conflicts

    2017-12-01

    In light of growing water scarcity, virtual water, or the water embedded in key water-intensive commodities, has been an active area of debate among practitioners and academics alike. As of yet, however, there is no consensus on whether water scarcity affects conflict behavior and we still lack empirical research intending to account for the role of virtual water in affecting the odds of militarized disputes between states. Using quantitative methods and data on virtual water trade, we find that bilateral and multilateral trade openness reduce the probability of war between any given pair of countries, which is consistent with the strategic role of this important commodity and the opportunity cost associated with the loss of trade gains. We also find that the substantive effect of virtual water trade is comparable to that of oil and gas, the archetypal natural resources, in determining interstate conflicts' probability.

  12. Bilaterally Weighted Patches for Disparity Map Computation

    Directory of Open Access Journals (Sweden)

    Laura Fernández Julià

    2015-03-01

    Full Text Available Visual correspondence is the key for 3D reconstruction in binocular stereovision. Local methods perform block-matching to compute the disparity, or apparent motion, of pixels between images. The simplest approach computes the distance of patches, usually square windows, and assumes that all pixels in the patch have the same disparity. A prominent artifact of the method is the "foreground fattening effet" near depth discontinuities. In order to find a more appropriate support, Yoon and Kweon introduced the use of weights based on color similarity and spatial distance, analogous to those used in the bilateral filter. This paper presents the theory of this method and the implementation we have developed. Moreover, some variants are discussed and improvements are used in the final implementation. Several examples and tests are presented and the parameters and performance of the method are analyzed.

There was no bleeding or nipple discharge. He was diagnosed with human immunodeficiency virus (HIV infection 16 months ago and was initiated on antiretroviral therapy (ARV, which consisted of zidovudine, lamivudine and efavirenz. As his CD4 cell count at diagnosis was less than 200 cells/mm3, he was prescribed trimethoprim-sulphamethoxazole (Bactrim for prophylaxis against pneumonia due to pneumocystis jirovecii. Physical examination was unremarkable except for bilateral breast enlargement and right-sided old shingles scar in the T4 dermatome distribution.

  14. Bilateral Trade Flows and Income Distribution Similarity

    Science.gov (United States)

    2016-01-01

    Current models of bilateral trade neglect the effects of income distribution. This paper addresses the issue by accounting for non-homothetic consumer preferences and hence investigating the role of income distribution in the context of the gravity model of trade. A theoretically justified gravity model is estimated for disaggregated trade data (Dollar volume is used as dependent variable) using a sample of 104 exporters and 108 importers for 1980–2003 to achieve two main goals. We define and calculate new measures of income distribution similarity and empirically confirm that greater similarity of income distribution between countries implies more trade. Using distribution-based measures as a proxy for demand similarities in gravity models, we find consistent and robust support for the hypothesis that countries with more similar income-distributions trade more with each other. The hypothesis is also confirmed at disaggregated level for differentiated product categories. PMID:27137462

    2010-01-01

    External beam radiotherapy (EBRT) for retinoblastoma has traditionally been done with conventional radiotherapy techniques which resulted high doses to the surrounding normal tissues. A 20 month-old girl with group D bilateral retinoblastoma underwent intensity modulated radiotherapy (IMRT) to both eyes after failing chemoreduction and focal therapies including cryotherapy and transpupillary thermotherapy. In this report, we discuss the use of IMRT as a method for reducing doses to adjacent normal tissues while delivering therapeutic doses to the tumour tissues compared with 3-dimensional conformal radiotherapy (3DCRT). At one year follow-up, the patient remained free of any obvious radiation complications. Image guided IMRT provides better dose distribution than 3DCRT in retinoblastoma eyes, delivering the therapeutic dose to the tumours and minimizing adjacent tissue damage

  16. Binaural enhancement for bilateral cochlear implant users.

    Brown, Christopher A

    2014-01-01

    Bilateral cochlear implant (BCI) users receive limited binaural cues and, thus, show little improvement to speech intelligibility from spatial cues. The feasibility of a method for enhancing the binaural cues available to BCI users is investigated. This involved extending interaural differences of levels, which typically are restricted to high frequencies, into the low-frequency region. Speech intelligibility was measured in BCI users listening over headphones and with direct stimulation, with a target talker presented to one side of the head in the presence of a masker talker on the other side. Spatial separation was achieved by applying either naturally occurring binaural cues or enhanced cues. In this listening configuration, BCI patients showed greater speech intelligibility with the enhanced binaural cues than with naturally occurring binaural cues. In some situations, it is possible for BCI users to achieve greater speech intelligibility when binaural cues are enhanced by applying interaural differences of levels in the low-frequency region.

    Full Text Available Bilateral adrenal hemorrhage (BAH is a rare complication typically seen in critically ill patients, which can lead to acute adrenal insufficiency and death unless it is recognized promptly and treated appropriately. We describe the case of a 64-year-old man with polycythemia vera found to be unresponsive with fever, hypotension, tachycardia, and hypoglycemia. Electrocardiogram showed ST-elevation with elevated troponin, hemoglobin, prothrombin time, and partial thromboplastin time. He required aggressive ventilator and vasopressor support. Despite primary coronary intervention, he remained hypotensive. Random cortisol level was low. He received stress dose hydrocortisone with immediate hemodynamic stability. BAH was highly suspected and was confirmed by non-contrast abdominal computed tomography. Prompt recognition and timely initiated treatment remain crucial to impact the mortality associated with acute adrenal insufficiency.

    2015-01-01

    Full Text Available Vernal Keratoconjunctivits (VKC is a bilateral recurrent allergic interstitial conjunctival inflammation with a periodic seasonal incidence and of self limiting nature, mainly affecting the younger population. Patients of VKC on steroid therapy are at higher risk of developing steroid induced glaucoma. Raised intraocular pressure due to steroids typically occurs within few weeks of starting steroid therapy and comes back to normal on immediate stoppage of steroids. A case of steroid induced glaucoma in a 30 years old female with vernal keratoconjunctivitis. She was on topical steroids for 3-4 years. She was incompliant with the instructions to stop steroids. She eventually developed steroid induced glaucoma and glaucomatous optic neuropathy with tunnel vision.

    Two work-horse approaches to postmastectomy breast reconstruction are the deep inferior epigastric perforator flap and the superior gluteal artery perforator (SGAP) flap [and its variation, the lateral septocutaneous superior gluteal artery perforator flap]. Our purpose was fourfold: 1) to analyze our experience with the SGAP flaps for simultaneous bilateral breast reconstruction; 2) to analyze our experience with lateral septocutaneous superior gluteal artery perforator flaps for that procedure; 3) to compare our results with those in the literature; and 4) to highlight the importance of preoperative three-dimensional computed tomographic angiography. A retrospective chart review was completed for 23 patients who underwent breast reconstruction between December 2005 and January 2010 via an SGAP flap (46 flaps). We reviewed flap weight, ischemia time, length of stay, overall flap survival, fat necrosis development, and emergency re-exploration. Mean weights were 571.2 ± 222.0 g (range 186-1,117 g) and 568.0 ± 237.5 g (range 209-1,115 g) for the left and right buttock flap, respectively. Mean ischemia time was 129.1 ± 15.7 and 177.7 ± 24.7 minutes for the first and second flap, respectively. Mean hospital stay was 5.3 ± 2.5 days. All flaps survived. Fat necrosis developed in five flaps (10.8%), and emergency re-exploration was required in three patients (three flaps). When harvesting abdominal tissue is a poor option, the SGAP flap is an efficacious procedure for patients desiring autologous breast reconstruction, and bilateral procedures can be performed simultaneously.

    Utility of visual impairment caused by amblyopia is important for the cost-effectiveness of screening for amblyopia (lazy eye, prevalence 3-3.5 %). We previously measured decrease of utility in 35-year-old persons with unilateral persistent amblyopia. The current observational case-control study aimed to measure loss of utility in patients with amblyopia with recent decrease of vision in their better eye. As these patients are rare, the sample was supplemented by patients with bilateral age-related macular degeneration with similar decrease of vision. From our out-patient department, two groups of patients with recent deterioration to bilateral visual acuity less than Snellen 0.5 (bilateral visual impairment, BVI) were recruited, with either persistent amblyopia and age-related macular degeneration (AMB + AMD), or with bilateral age-related macular degeneration (BAMD). To measure utility, the time trade-off method and the standard gamble method were applied through interviews. Correlations were sought between utility values and visual acuity, age and Visual Function Questionnaire-25 scores. Seventeen AMB + AMD patients (mean age 72.9 years), and 63 BAMD patients (mean age 79.6 years) were included in the study. Among AMB + AMD, 80 % were willing to trade lifetime in exchange for cure. The overall mean time trade-off utility was 0.925. Among BAMD, 75 % were willing to trade, utility was 0.917. Among AMB + AMD, 38 % accepted risk of death in exchange for cure, overall mean standard gamble utility was 0.999. Among BAMD, 49 % accepted risk of death, utility was 0.998. Utility was not related to visual acuity but it was to age (p = 0.02). Elderly patients with BVI, caused by persistent amblyopia and age-related macular degeneration (AMD) or by bilateral AMD, had an approximately 8 % loss of TTO utility. Notably, the 8 % loss in elderly with BVI differs little from the 3.7 % loss we found previously in 35-year-old persons with unilateral

    Full Text Available Relata-se o caso de um paciente com dispnéia intensa ao se deitar, em que foram excluídas doenças pulmonares, neuromusculares ou cardíacas, cuja investigação revelou paresia diafragmática bilateral. Um sinal chave para o diagnóstico foi a evidência de respiração paradoxal com o doente em decúbito supino. Havia piora da oxigenação e da capacidade vital forçada com a mudança da posição ortostática para supina. A fluoroscopia ortostática foi normal. A pressão inspiratória máxima estava muito reduzida. A estimulação elétrica transcutânea do diafragma foi normal, e a eletroestimulação do nervo frênico mostrou ausência de resposta, permitindo o diagnóstico de paresia bilateral do diafragma.We report the case of a patient with severe dyspnea upon reclining. Lung disease, neuromuscular disorders and heart disease were ruled out. However, during the course of the investigation, bilateral diaphragmatic paresis was discovered. A key sign leading to the diagnosis was evidence of paradoxical respiration in the dorsal decubitus position. When the patient was moved from the orthostatic position to the dorsal decubitus position, oxygenation and forced vital capacity worsened. The orthostatic fluoroscopy was normal. Maximal inspiratory pressure was severely reduced. The responses to transcutaneous electric stimulation of the diaphragm were normal. However, electric stimulation of the phrenic nerve produced no response, leading to the diagnosis of bilateral diaphragmatic paresis.

    To present an economic-analysis comparison of simultaneous and sequential bilateral cataract surgery. Helsinki University Eye Hospital, Helsinki, Finland. Economic analysis. Effects were estimated from data in a study in which patients were randomized to have bilateral cataract surgery on the same day (study group) or sequentially (control group). The main clinical outcomes were corrected distance visual acuity, refraction, complications, Visual Function Index-7 (VF-7) scores, and patient-rated satisfaction with vision. Health-care costs of surgeries and preoperative and postoperative visits were estimated, including the cost of staff, equipment, material, floor space, overhead, and complications. The data were obtained from staff measurements, questionnaires, internal hospital records, and accountancy. Non-health-care costs of travel, home care, and time were estimated based on questionnaires from a random subset of patients. The main economic outcome measures were cost per VF-7 score unit change and cost per patient in simultaneous versus sequential surgery. The study comprised 520 patients (241 patients included non-health-care and time cost analyses). Surgical outcomes and patient satisfaction were similar in both groups. Simultaneous cataract surgery saved 449 Euros (€) per patient in health-care costs and €739 when travel and paid home-care costs were included. The savings added up to €849 per patient when the cost of lost working time was included. Compared with sequential bilateral cataract surgery, simultaneous bilateral cataract surgery provided comparable clinical outcomes with substantial savings in health-care and non-health-care-related costs.

    Oversight programs are conducted by the U.S. Department of Energy to review activities carried out by field and contractor organizations. Two of these oversight programs focus on safeguards and security and on safety and health activities. These two programs are independent, but share many common objectives and review techniques. The mutual potential benefit was recognized from an exchange of information on review techniques. The first step in this exchange was the participation by an Office of Security Evaluations (OSE) staff member with the Office of Nuclear Safety (ONS) during their planning, conduct and reporting of a Technical Safety Appraisal (TSA). This paper briefly describes the OSE and ONS programs. It also identifies and analyzes the similarities and differences of the two programs. The purpose of this paper is to provide perspectives on the approach taken, the techniques used and the differences between two oversight programs conducted by the Department of Energy

      UXC + detectors As explained in detail in the November 2011 bulletin, the bellows unit at −18.5 m from the CMS interaction point was identified as a prime candidate for the regularly occurring pressure spikes which occasionally led to sustained severe background conditions in 2011, affecting dead time and data quality. Similar regions in LHC with vacuum instabilities were observed to be close to bellows, which radiography showed to have distorted RF-fingers — on removal, they proved to have been severely overheated. The plans for the Year-End Technical Stop were adapted to prioritise radiography of the bellows at 16 m to 18 m either end of CMS. Excellent work by the beam pipe, survey and heavy mechanical teams allowed the X-rays to be taken as planned on 20th December, showing that the bellow at −18.5m had an obvious non-conformity. The RF-fingers were found inside the end of the opposing flared pipe instead of outside. In addition, the overlap between fingers and...

    Juvenile nasopharyngeal angiofibroma (JNA) is the most common benign neoplasm of the nasopharynx. Almost always unilateral on diagnosis, JNAs are locally invasive and may extend across the midline, giving a false bilateral appearance; as such, true bilateral JNA is exceedingly rare. We present a recent case of true bilateral JNA. Single case report of a patient with bilateral JNA, including clinical presentation, diagnosis, and management. The patient presented with unilateral nasal obstruction and recurrent epistaxis. Computed tomography and magnetic resonance imaging demonstrated bilateral, noncontiguous masses. Angiography revealed independent vascular supplies from each respective side with no bilateral supply noted. The patient underwent preoperative embolization followed by endoscopic surgical removal of the larger mass; no complications were noted. Follow-up at 2 years demonstrated no recurrence or growth. The vast majority of JNAs are unilateral, though invasive growth to the contralateral side may appear "bilateral" in presentation. Proper identification of true bilateral JNA is helpful in guiding management, wherein excision of both tumors may not be necessary. © 2014 ARS-AAOA, LLC.

  15. Simultaneous Bilateral Transient Osteoporosis of the Hip without Pregnancy

    2016-01-01

    Full Text Available Transient osteoporosis of the hip (TOH is a rare disorder characterized by acute severe coxalgia and temporary osteopenia in the proximal femur. Although most cases were unilateral or staged bilateral TOH, some authors reported that the pregnant patients simultaneously had TOH in their bilateral hips. However, there has been no report of simultaneous bilateral TOH in the patient without pregnancy. A 25-year-old Japanese woman without pregnancy had acute simultaneous bilateral hip pain. Plain X-ray of the bilateral hips did not show a periarticular osteopenia. However, magnetic resonance image obtained one week after the onset demonstrated increased T2-weighted signal intensity and decreased T1-weighted signal intensity in the bilateral femoral heads. She was treated conservatively, and follow-up magnetic resonance image at seven weeks after the onset returned to normal bone marrow signal intensity. Her bilateral coxalgia subsided gradually. At one year after the onset, she had no sign of symptomatic flair. Our experience with this case indicates that recognizing the possibility of simultaneous bilateral TOH is important unless the patient is pregnant, and magnetic resonance image is predictable test to make a diagnosis of TOH, even in the absence of abnormal finding on plain X-ray.

    Full Text Available Background. The incidence of tubal ectopic gestation caused by schistosomiasis induced tubal pathology is undocumented in this environment, which may be due to rarity of this pathology. Bilateral tubal gestation is common in patients that have undergone in vitro fertilization. We report a hitherto undocumented case of spontaneous bilateral ectopic gestation following tubal schistosomiasis. Case Report. Mrs. OB was a 32-year-old G4P3+0 (3 alive woman who complained of abdominal pain and bleeding per vaginam of 4 and 2 days’ duration respectively following 8 weeks of amenorrhea. A clinical impression of ruptured ectopic gestation was confirmed by ultrasound scanning. She had bilateral salpingectomy with histology of specimens showing bilateral ectopic gestation with Schistosoma haematobium induced salpingitis (findings of Schistosoma haematobium ova noted on slide. Conclusion. Schistosoma induced salpingitis is a rare but possible cause of bilateral tubal gestation.

    The aim of this article is to report the MRI features of bilateral parotid haemangiomas of infancy and highlight the diagnostic and prognostic value of MRI especially with regard to those lesions that may cause respiratory compromise. Retrospective review of MRI scans in six infants with bilateral parotid haemangiomas. The bilateral haemangiomas were symmetrical in all but one patient. On T1-weighted images the masses were isointense to muscle and on T2 they were hyperintense with numerous small vessels giving a septated appearance. There was vivid enhancement with gadolinium in all cases. In three patients, deep bilateral extensions were demonstrated involving the parapharyngeal spaces resulting in respiratory compromise which required tracheostomy. Bilateral parotid haemangiomas are rare, but when present may have deep extensions, which can result in respiratory compromise requiring tracheostomy. (orig.)

    2013-01-01

    Branchial arch anomalies are one of the most common congenital anomalies that are usually unilateral and bilateral presentation is rare. The simultaneous presence of bilateral second branchial arch anomalies along with bilateral first arch anomalies is extremely rare, with only three such cases reported in the literature. We present two non-syndromic cases of coexisting bilateral first and second arch anomalies. Developmental anomalies of the branchial apparatus account for 17% of all paediatric cervical masses and are the most common type of congenital cervical mass. They usually present in the paediatric age group. About 96–97% of these anomalies are unilateral. Bilateral presentation is seen in 2–3% having a strong familial association. Congenital syndromes also have been associated with first and second branchial arch anomalies. Thorough clinical examination and investigations should be done to rule out these syndromes.

  10. Bilateral movements increase sustained extensor force in the paretic arm.

    Kang, Nyeonju; Cauraugh, James H

    2018-04-01

    Muscle weakness in the extensors poststroke is a common motor impairment. Unfortunately, research is unclear on whether bilateral movements increase extensor force production in the paretic arm. This study investigated sustained force production while stroke individuals maximally extended their wrist and fingers on their paretic arm. Specifically, we determined isometric force production in three conditions: (a) unilateral paretic arm, (b) unilateral nonparetic arm, and (c) bilateral (both arms executing the same movement simultaneously). Seventeen chronic stroke patients produced isometric sustained force by executing wrist and fingers extension in unilateral and bilateral contraction conditions. Mean force, force variability (coefficient of variation), and signal-to-noise ratio were calculated for each contraction condition. Analysis of two-way (Arm × Type of Condition: 2 × 2; Paretic or Nonparetic Arm × Unilateral or Bilateral Conditions) within-subjects ANOVAs revealed that the bilateral condition increased sustained force in the paretic arm, but reduced sustained force in the nonparetic arm. Further, although the paretic arm exhibited more force variability and less signal-to-noise ratio than the nonparetic arm during a unilateral condition, there were no differences when participants simultaneously executed isometric contractions with both arms. Our unique findings indicate that bilateral contractions transiently increased extensor force in the paretic arm. Implications for Rehabilitation Bilateral movements increased isometric wrsit extensor force in paretic arms and redcued force in nonparetic arms versus unilateral movements. Both paretic and nonparetic arms produced similar force variability and signal-to-noise ratio during bilateral movements. Increased sustained force in the paretic arm during the bilateral condition indicates that rehabilitation protocols based on bilateral movements may be beneficial for functional recovery.

  12. Bilateral maculopathy following electrical burn: case report

    Directory of Open Access Journals (Sweden)

    Leandro Dario Faustino

    Full Text Available CONTEXT: Electrical burns are an important etiology in dealing with patients suffering from burns. In situations of extensive deep lesions of multiple organs and systems affecting young and economically active people, there is a need for expensive multidisciplinary treatment, with a high socioeconomic cost for the community. Among the permanent injuries that explain this high cost, eye injuries stand out, since they are widely disabling. Although rare, lesions of the posterior segment of the eye are associated with higher incidence of major sequelae, and thus deserve special attention for dissemination and discussion of the few cases observed.CASE REPORT: The authors report the case of a patient who suffered high-voltage electrical burns and presented bilateral maculopathy, which evolved with a need for a surgical approach to repair retinal detachment and permanent low visual acuity.CONCLUSION: This report highlights the rarity of the etiology of maculopathy and the need for campaigns for prevention not only of burns in general, but also especially of electrical burns.

  13. Bilateral talipes equinovarus from Tikal, Guatemala.

    Wright, Lori E

    2011-03-01

    An incomplete skeleton recovered from a multiple, secondary burial at Tikal, Guatemala, shows malformed foot bones consistent with a diagnosis of bilateral idiopathic talipes equinovarus. Bones attributable to the skeleton include paired bowed fibulae, fragmentary calcanei, complete tali, naviculars, cuneiforms, metatarsals, and some phalanges. The tali are reduced in size, flattened, and hyperextended, with the tibia partially articulated on the calcaneus, posterior to the talus. The cuboid and cuneiforms show marked contraction of the inferior surfaces, and angulation. The metatarsals and phalanges present minor changes to the articulations, and slender shafts. Articulated, both feet show marked equinovarus deformity, with weight carried on the lateral margin and superior surface of the feet. Key conditions considered in the differential diagnosis are those producing an equinovarus or a calcaneocavovarus deformation, especially progressive neuromuscular disorders. This paper describes the nature of the bony changes, reconstructs the morphology of the feet, and offers a differential diagnosis. Scholars of the ancient Maya have identified artwork that appears to depict talipes equinovarus, although there was no osteological evidence for the condition among the Maya prior to the diagnosis of this case.

    Full Text Available Background. The challenge in managing patients undergoing renal transplantation is how to achieve optimum levels of anticoagulation to avoid both clotting and postoperative bleeding. We report a rare case of severe postoperative retroperitoneal bleeding including psoas haematomata complicating renal transplantation. Case Report. SM, a 55-year-old female, had a past history of aortic valve replacement, cerebrovascular event, and thoracic aortic aneurysm and was on long-term warfarin that was switched to enoxaparin 60 mg daily a week prior to her living donor transplantation. Postoperatively, she was started on a heparin infusion, but this was complicated by a large retroperitoneal bleed requiring surgical evacuation on the first postoperative day. Four weeks later, she developed features compatible with acute femoral neuropathy and a CT scan revealed bilateral psoas haematomata. Following conservative management, she made steady progress and was discharged home via a community hospital 94 days after transplantation. At her last visit 18 months after transplantation, she had returned to full fitness with excellent transplant function. Conclusion. Patients in established renal failure who require significant anticoagulation are at increased risk of bleeding that may involve prolonged hospitalisation and more protracted recovery and patients should be carefully counselled about this.

    A paradigmatic example of an emotional bias in decision making is the framing effect, where the manner in which a choice is posed--as a potential loss or a potential gain--systematically biases an ensuing decision. Two fMRI studies have shown that the activation in the amygdala is modulated by the framing effect. Here, contrary to an expectation based on these studies, we show that two patients with Urbach-Wiethe (UW) disease, a rare condition associated with congenital, complete bilateral amygdala degeneration, exhibit an intact framing effect. However, choice preference in these patients did show a qualitatively distinct pattern compared to controls evident in an increased propensity to gamble, indicating that loss of amygdala function does exert an overall influence on risk-taking. These findings suggest either that amygdala does contribute to decision making but does not play a causal role in framing, or that UW is not a pure lesion model of amygdala function. 2010 Elsevier Ltd.

    Pulmonary tuberculosis (TB) during pregnancy mimics some of the physiological changes that occur during pregnancy. Diagnosis is challenging, especially when the patient presents with acute respiratory distress. The incidence of pleural effusion in TB is 3-25% and in the majority of patients, is unilateral. We describe the intensive care management of a 27-year-old pregnant woman admitted to our hospital with life threatening respiratory distress and circulatory shock. She continued to have severe metabolic and respiratory acidosis with shock in spite of the resuscitative measures undertaken. At that point, a bedside lung ultrasonography showed bilateral pleural effusion which was followed with therapeutic thoracocentesis of the right side. This resulted in the stabilization of the respiratory mechanics and haemodynamics of the patient. The pleural fluid culture tested positive for acid fast bacilli after 4 weeks in the intensive care unit. Anti-TB therapy was started and she made a rapid recovery with liberation from mechanical ventilation. The early use of bedside lung ultrasonography was instrumental in the successful management of this patient.

    Endoscopic reintervention for stent occlusions following bilateral self-expandable metallic stent (SEMS) placement for malignant hilar biliary obstruction (MHBO) is challenging, and time to recurrent biliary obstruction (RBO) of the revisionary stent remains unclear. We aimed to clarify a suitable reintervention method for stent occlusions following bilateral SEMS placement for MHBO. Between 2002 and 2014, 52 consecutive patients with MHBO who underwent endoscopic reintervention for stent occlusion after bilateral SEMS placement were enrolled at two university hospitals and one tertiary care referral center. We retrospectively evaluated the technical and functional success rates of the reinterventions, and the time to RBO of the revisionary stents. Technical and functional success rates of the reinterventions were 92% (48/52) and 90% (43/48), respectively. Univariate analysis did not determine any significant predictive factors for technical and functional failures. Median time to RBO of the revisionary stents was 68 days. Median time to RBO was significantly longer for revisionary SEMS placement than for plastic stent placement (131 days vs 47 days, respectively; log-rank test, P = 0.005). Revisionary SEMS placement was the only independent factor that was significantly associated with a longer time to RBO of the revisionary stent in the multivariate Cox proportional hazards analysis (hazard ratio 0.37; 95% confidence interval 0.14-0.95; P = 0.039). Revisionary SEMS placement is a suitable endoscopic reintervention method for stent occlusion following bilateral SEMS placement from the perspective of time to RBO of the revisionary stent. © 2016 Japan Gastroenterological Endoscopy Society.

    We reported a high incidence of thrombosis, central pulmonary artery hypoplasia, and mortality for bilateral bidirectional cavopulmonary shunts. We hypothesized that technical modifications in the cavopulmonary anastomosis and anticoagulation would limit thrombus and central pulmonary artery hypoplasia, and thereby improve outcomes. Sixty-one patients (median age, 8.4 months; weight, 6.6 kg) underwent bilateral bidirectional cavopulmonary shunt from 1990 to 2007. The cohort was divided into 2 groups: 1) the conventional group (1990-1999, n = 37) and 2) the V-shaped group, with a hemi-Fontan or modification in which the cavae were anastomosed to the pulmonary artery adjacent to each other so they formed the appearance of a V (1999-2007, n = 24). Central and branch pulmonary artery growth, survival, and reinterventions were determined. The pre-Fontan study showed equivalent superior venae cavae and Nakata indices. The central pulmonary artery index and central pulmonary artery/Nakata index ratio were significantly higher in the V-shaped group (P analysis showed anastomotic strategy, low saturation, and thrombosis were predictors for death. Anastomotic strategy, lack of anticoagulation, thrombosis, and small superior venae cavae were predictors for reintervention (P strategy affected reintervention. Anastomotic strategy and postoperative thrombus affected mortality. 2010 The American Association for Thoracic Surgery. Published by Mosby, Inc. All rights reserved.

    of the patients presented with bilateral SP. Preoperative HRCT revealed that all of the patients had bilateral apical bullae. We reviewed the surgical indications, surgical procedures, and outcomes. RESULTS: All of the patients were successfully submitted to this approach for bilateral bullectomy, and there were no intraoperative complications. The median time to chest tube removal was 4.2 days, and the median length of the postoperative hospital stay was 5.2 days. The median postoperative follow-up period was 11.2 months. One patient experienced recurrence of left SP three weeks after the surgery and underwent pleural abrasion. CONCLUSIONS: Bilateral bullectomy through uniportal VATS combined with contralateral access to the anterior mediastinum is technically reliable and provides favorable surgical outcomes for patients with bilateral SP who develop bilateral apical bullae. However, among other requirements, this surgical procedure demands that surgeons be experienced in VATS and that the appropriate thoracoscopic instruments are available.

    The optimal treatment for bilateral hearing loss continues to evolve as cochlear implant (CI) and hearing aid technologies advance, as does our understanding of the central auditory system. Ongoing discussions continue on the validity and feasibility of bilateral CI in terms of performance, justification of need, medical/surgical safety concerns, and economics. The purpose of this review article is to provide an update on the advantages and disadvantages of bilateral CI and to provide a discussion on timing (simultaneous vs. sequential), technology (bimodal vs. binaural) and feasibility. Binaural advantages are found in both adult and pediatric bilateral CI recipients, the greatest being the head shadow effect and improvements in localization and loudness summation. This theoretically offers an advantage over their unilateral implanted counterparts in terms of improved sound localization and enhanced speech perception under noisy conditions. Most investigators agree that bilateral stimulation during critical periods of development is paramount for optimizing auditory functioning in children. Currently, bilateral CI is widely accepted as a safe and effective means of bilateral auditory stimulation.

    IgG4-related disease (IgG4-RD) is an idiopathic inflammatory condition that causes pseudotumor formation in single or multiple organs, including those of the head and neck. Temporal bone involvement is rare, with only 3 cases of unilateral temporal bone IgG4-RD described in the literature. We report the first known case of IgG4-RD of bilateral temporal bones and describe its clinical presentation, diagnosis, and treatment. The patient was a 52-year-old man with latent tuberculosis (TB) who presented with a 10-year history of bilateral profound hearing loss and vestibular dysfunction. Computed tomography and magnetic resonance imaging demonstrated bilateral labyrinthine destruction with invasion of the posterior fossa. Immunoglobulin level testing showed elevated total serum IgG levels with normal IgG4 levels. Bilateral mastoidectomies were performed, with biopsy samples demonstrating IgG4 staining with IgG4-positive plasma cells up to 40/HPF (high power field) on the right and 20/HPF on the left, consistent with bilateral IgG4-RD. IgG4-RD of bilateral temporal bones presents with chronic and progressive bilateral hearing loss and vestibular dysfunction. Clinical presentation and radiologic findings are nonspecific, and definitive diagnosis must be made with histopathology and immunostaining. Corticosteroids are therapeutic, but surgical resection may be necessary for temporal bone IgG4-RD to improve long-term remission.

    Full Text Available We reported a case of cryptococcal meningitis presenting with bilateral optic neuropathy in an immunocompetent patient. A 64-year-old Malay gentleman with no medical comorbidities presented with acute bilateral blurring of vision for a week, which was associated with generalised throbbing headache and low grade fever. He also had somnolence and altered consciousness. Visual acuity in both eyes was no perception of light with poor pupillary reflexes. Extraocular muscle movements were normal. Anterior segments were unremarkable bilaterally. Fundoscopy revealed bilateral optic disc swelling. CT scan of the brain showed multifocal infarct, but no meningeal enhancement or mass. Cerebrospinal fluid opening pressure was normal, while its culture grew Cryptococcus neoformans. A diagnosis of cryptococcal meningitis with bilateral optic neuropathy was made. Patient was treated with a six-week course of intravenous fluconazole and started concomitantly on a fortnight's course of intravenous amphotericin B. After that, his general condition improved, but there was still no improvement in his visual acuity. On reviewing at two months post-initiation of treatment, fundi showed bilateral optic atrophy. Bilateral optic neuropathy secondary to cryptococcal meningitis was rare. The prognosis was guarded due to the sequelae of optic atrophy. Anti-fungal medication alone may not be sufficient to manage this condition. However, evidence for other treatment modalities is still lacking and further clinical studies are required.

    Among the publications of CDC Climat Research, 'Climate Briefs' presents, in a few pages, hot topics in climate change policy. This issue addresses the following points: In order to achieve its long-term emission reduction target following the Fukushima incident, Japan would rely more heavily on international offsetting activities. Concurrent to vigorous proposals to reform the CDM, Japan is also promoting an offset crediting scheme through bilateral agreements with developing countries as a post-2012 market mechanism. Despite potential benefits, issues relating to the accounting rules, environmental integrity and implications to carbon markets warrant further consideration prior to international recognition

    Flat feet (pes planus) have been implicated in multiple musculoskeletal complaints, which are often exacerbated by lack of appropriate arch support or intense exercise. To investigate the efficacy of osteopathic manipulative treatment (OMT) on a patient (K.K.H.) with mountaineering-induced bilateral plantar paresthesia and to assess the association of pes planus with paresthesia in members of the mountaineering expedition party that accompanied the patient. A patient history and physical examination of the musculoskeletal system were performed. The hindfoot, midfoot, forefoot, big toe, and distal toes were evaluated for neurologic function, specifically pin, vibration, 10-g weight sensitivity, and 2-point discrimination during the 4-month treatment period. To determine if OMT could augment recovery, the patient volunteered to use the contralateral leg as a control, with no OMT performed on the sacrum or lower back. To determine if pes planus was associated with mountaineering-induced paresthesia, a sit-to-stand navicular drop test was performed on members of the expedition party. Osteopathic manipulative treatment improved fibular head motion and muscular flexibility and released fascial restrictions of the soleus, hamstring, popliteus, and gastrocnemius. The patient's perception of stiffness, pain, and overall well-being improved with OMT. However, OMT did not shorten the duration of paresthesia. Of the 9 expedition members, 2 experienced paresthesia. Average navicular drop on standing was 5.1 mm for participants with no paresthesia vs 8.9 mm for participants with paresthesia (t test, Pparesthesia. Early diagnosis of pes planus and treatment with orthotics (which may prevent neuropathies)--or, less ideally, OMT after extreme exercise--should be sought to relieve tension and discomfort. © 2014 The American Osteopathic Association.

    Objective: To investigate the clinical application of bilateral uterine arterial chemoembolization in treating massive hemorrhage due to uterine scar pregnancy after cesarean section. Methods: Sixteen patients with massive hemorrhage due to cesarean scar pregnancy were enrolled in the study, the mean blood loss was (2 200 ± 1 400) ml. With Seldinger technique, abdominal angiography by using a pig-tail catheter was carried out. When bilateral uterine arterial bleeding was confirmed, selective or super-selective catheterization was employed and bilateral uterine arterial chemoembolization with infusion of 5-Fu or methotrexate (MTX) together with gelatin sponge via the catheters was conducted. The clinical results were observed. Results: The technical success was achieved in all 16 patients. No recurrent bleeding occurred during a follow-up of 3-6 months. Conclusion: The emergency bilateral uterine arterial chemoembolization is a safe and effective treatment for massive hemorrhage due to cesarean scar pregnancy with no serious complications, therefore, this technique is worth being used in clinical practice.

    Full Text Available Maisonneuve fractures result from a disruption of the medial ankle structures and a proximal fibular fracture. Patient complaints can be misleading and there is a significant rate of delayed diagnosed injuries. We present a case of bilateral Maisonneuve fractures after a fall due to a syncopal collapse. A precise clinical examination led to this rare diagnosis. The injuries were treated with syndesmotic screw fixation, removal of hardware followed after 6 weeks. The patient was asymptomatic at threemonths follow up. Patients with bilateral injuries undergoing standard surgical treatment can gain full recovery, but high suspicion in clinical examination is needed to detect this uncommon bilateral injury.

    To report a phenomenon of optical nerve atrophy secondary to lateral occipital lobe infarction. Two successive patients with unilateral occipital lobe infarction who experienced bilateral optical nerve atrophy during the follow-up underwent cranial imaging, fundus photography, and campimetry. Each patient was diagnosed with occipital lobe infarction by cranial MRI. During the follow-up, a bilateral optic atrophy was revealed, and campimetry showed a right homonymous hemianopia of both eyes with concomitant macular division. Bilateral optic atrophy was related to occipital lobe infarction, and a possible explanation for the atrophy was transneuronal degeneration caused by occipital lobe infarction.

    We present a case of a patient with Anton's syndrome (i.e., visual anosognosia with confabulations), who developed bilateral occipital lobe infarct. Bilateral occipital brain damage results in blindness, and patients start to confabulate to fill in the missing sensory input. In addition, the patient occasionally becomes agitated and talks to himself, which indicates that, besides Anton's syndrome, he might have had Charles Bonnet syndrome, characterized by both visual loss and hallucinations. Anton syndrome, is not so frequent condition and is most commonly caused by ischemic stroke. In this particular case, the patient had successive bilateral occipital ischemia as a result of massive stenoses of head and neck arteries.

    Full Text Available The aim of this work is the integration of a virtual environment containing a deformable object, manipulated by an open kinematical chain virtual slave robot, to a bilateral teleoperation scheme based on a real haptic device. The virtual environment of this hybrid bilateral teleoperation system combines collision detection algorithms, dynamical, kinematical and geometrical models with a position–position and/or force–position bilateral control algorithm, to produce on the operator side the reflected forces corresponding to the virtual mechanical interactions, through a haptic device. Contact teleoperation task over the virtual environment with a flexible object is implemented and analysed.

The described abnormality in CBPS is polymicrogyria located in the frontal, parietal, and/or occipital lobes. A few syndromes or abnormalities associated with this syndrome have been documented. Pituitary abnormalities are rare disorders. Association of CBPS with pituitary abnormalities has not been reported previously. In this case, a combination of bilateral perisylvian polymicrogyria with pituitary hypoplasia and ectopic neurohypophysis, caused by a possible single common insult, is presented. (orig.)

  2. Laparoscopic Partial Adrenalectomy for Bilateral Cortisol-secreting Adenomas

    Full Text Available Bilateral cortisol-secreting adenomas are a rare cause of Cushing's syndrome. We report a case of a 35-year-old woman who presented with ACTH-independent Cushing's syndrome and bilateral adrenal adenomas. Adrenal venous sampling confirmed both adenomas to be hyper-secreting cortisol. She underwent bilateral laparoscopic adrenalectomy; total right and partial left adrenalectomies. At 2-year follow-up, she is maintained on low-dose fludrocortisone and hydrocortisone, and without recurrence of hypercorticolism. Laparoscopic partial adrenalectomy is a feasible option for this rare condition; however, long-term follow-up is needed to determine her total independence from steroid usage.

  3. Bilateral fusion of permanent mandibular incisors: A case report

    Full Text Available This case report showing a classical presentation of bilateral fusion of permanent mandibular incisors in a child patient for dental attention. Fusion defined as the merger of two adjacent tooth germs producing one tooth. These teeth may be fused by enamel, dentin, or both. The fused crown is broader than non fused adjacent teeth and thus resembles gemination. However, tooth counting reveals decreased numbers. Fused teeth are rare in the permanent dentition. The incisors are reported to be fused in primary and permanent dentition, but bilateral fusion is a rare occurrence. Hence the case report of bilateral fusion in an 11-year-old boy is presented.

    To determine if the presence of bilateral implants, in addition to other anatomic and treatment-related variables, affects coverage of the target volume and dose to the heart and lung in patients receiving postmastectomy radiation therapy (PMRT). A total of 197 consecutive women with breast cancer underwent mastectomy and immediate tissue expander (TE) placement, with or without exchange for a permanent implant (PI) before radiation therapy at our center. PMRT was delivered with 2 tangential beams + supraclavicular lymph node field (50 Gy). Patients were grouped by implant number: 51% unilateral (100) and 49% bilateral (97). The planning target volume (PTV) (defined as implant + chest wall + nodes), heart, and ipsilateral lung were contoured and the following parameters were abstracted from dose-volume histogram (DVH) data: PTV D{sub 95%} > 98%, Lung V{sub 20}Gy > 30%, and Heart V{sub 25}Gy > 5%. Univariate (UVA) and multivariate analyses (MVA) were performed to determine the association of variables with these parameters. The 2 groups were well balanced for implant type and volume, internal mammary node (IMN) treatment, and laterality. In the entire cohort, 90% had PTV D{sub 95%} > 98%, indicating excellent coverage of the chest wall. Of the patients, 27% had high lung doses (V{sub 20}Gy > 30%) and 16% had high heart doses (V{sub 25}Gy > 5%). No significant factors were associated with suboptimal PTV coverage. On MVA, IMN treatment was found to be highly associated with high lung and heart doses (both p < 0.0001), but implant number was not (p = 0.54). In patients with bilateral implants, IMN treatment was the only predictor of dose to the contralateral implant (p = 0.001). In conclusion, bilateral implants do not compromise coverage of the target volume or increase lung and heart dose in patients receiving PMRT. The most important predictor of high lung and heart doses in patients with implant-based reconstruction, whether unilateral or bilateral, is treatment of

    Full Text Available This study tests weak and semi-strong form efficiency of the foreign exchange market in Sri Lanka during the recent float using six bilateral exchange rates. Weak-form efficiency is examined using unit root tests while semi-strong form efficiency is tested using co-integration, Granger causality tests and variance decomposition analysis. Results indicate that the Sri Lankan foreign exchange market is consistent with the weak-form of the efficient market hypothesis (EMH. However, the results provide evidence against the semi-strong version of the EMH. These results have important implications for government policy makers and participants in the foreign exchange market of Sri Lanka.

    Bilateral stent-in-stent (SIS) self-expandable metal stent placement is technically challenging for palliation of unresectable malignant hilar obstruction. In the SIS technique, the uniform large cell type biliary stent facilitates contralateral stent deployment through the mesh of the first metallic stent. This study aimed to assess the technical success and clinical effectiveness of this technique with a uniform large cell type biliary stent. Thirty-one patients who underwent bilateral SIS placement using a large cell type stent were reviewed retrospectively. All patients showed malignant hilar obstruction (Bismuth types II, III, IV) with different etiologies. Sixteen (51.6%) patients were male. The mean age of the patients was 67.0+/-14.0 years. Most patients were diagnosed as having hilar cholangiocarcinoma (58.1%) and gallbladder cancer (29.0%). Technical success rate was 83.9%. Success was achieved more frequently in patients without masses obstructing the biliary confluence (MOC) than those with MOC (95.2% vs 60.0%, P=0.03). Functional success rate was 77.4%. Complications occurred in 29.0% of the patients. These tended to occur more frequently in patients with MOC (50.0% vs 19.0%, P=0.11). Median time to recurrent biliary obstruction was 188 days and median survival was 175 days. The large cell type stent can be used efficiently for bilateral SIS placement in malignant hilar obstruction. However, the risk of technical failure increases in patients with MOC, and caution is needed to prevent complications for these patients.

    This thesis consists of four papers, of which paper 1 and 4 are co-written with Mikael Bask. Paper [1] implements chartists trading in a sticky-price monetary model for determining the exchange rate. It is demonstrated that chartists cause the exchange rate to "overshoot the overshooting equilibrium" of a sticky-price monetary model. Chartists base their trading on a short-long moving average. The importance of technical trading depends inversely on the time horizon in currency trade. The exc...

    Incineration of ion-exchange resins in a fluidized bed was studied on a pilot plant scale at the Technical Research Centre of Finland. Both granular and powdered resins were incinerated in dry and slurry form. Different bed materials were used in order to trap as much cesium and cobalt (inactive tracers) as possible in the bed. Also the sintering of the bed materials was studied in the presence of sodium. When immobilized with cement the volume of ash-concrete is 4 to 22% of the concrete of equal compressive strength acquired by direct solidification. Two examples of multi-purpose equipment capable of incinerating ion-exchange resins are presented. (orig.)

    Full Text Available Bilateral spontaneous tubal ectopic pregnancy is the rarest form of extra uterine pregnancy. The diagnosis is usually made intraoperatively and levels of serum BHCG and ultrasound has not been useful in the diagnosis of bilateral tubal ectopic pregnancy. A 33-year-old woman with 8 weeks amenorrhea and sever lower abdominal pain was admitted. A transvaginal pelvic ultrasound revealed left adnexal mass and massive fluid collection in the pelvis and abdomen. The serum BHCG was 5,700 mIU/ml and in laparotomy bilateral unruptured tubal pregnancy was noted. Left salpingectomy and right salpingostomy were performed. The diagnosis of bilateral spontaneous tubal ectopic pregnancy is usually made intraoperatively. Both tubes at the time of surgery should be closely examined in order to prevent maternal morbidity and mortality.

    2006-09-01

    To report the clinical picture of the rare association of nanophthalmos and pigmentary retinal dystrophy and its cataract surgery outcome. We report a case of a 60-year-old female who presented with bilateral slowly progressive visual loss. The patient presented with bilateral light perception visual acuity, exotropia, brunescent cataract hindering fundus examination and hypodontia. Ultrasonography revealed bilateral nanophthalmos. A visual-evoked potential was also performed preoperatively. Cataract surgery with +40D IOL implantation was uneventful. Postoperative fundus examination revealed pigmentary retinal dystrophy, confirmed by electrophysiologic tests. Glycosaminoglycan urinary excretion was normal. Congenital bilateral nanophthalmos may rarely be associated with pigmentary retinal dystrophy. We suggest thorough preoperative evaluation in nanophthalmic eyes for the exclusion of significant features concerning visual prognosis.

  14. Delayed-onset bilateral abducens paresis after head trauma

    2012-01-01

    Full Text Available Bilateral sixth nerve paresis following closed head injury, though rare, is a known entity. However, delayed-onset post-traumatic bilateral abducens paresis is extremely rare. We present two cases. The first patient had onset of bilateral abducens paresis 2 weeks after closed head injury and the second patient after 3 days. The cause in the former was detected to be chronic subdural hematoma and in the latter is speculated to be edema/ischemia due to injury to soft tissue structures housing these nerves. The delayed onset of bilateral abducens paresis following head injury may vary according to the cause. There may be another mechanism of injury apart from direct trauma. Though rare, it needs to be evaluated and may have a treatable cause like elevated intracranial pressure.

    Synchronous bilateral breast cancer is extremely rare in men and has not, up to date, been reported in Korea. A 54-year-old man presented with a palpable mass in the right breast. The right nipple was retracted and bilateral axillary accessory breasts and nipples were present. On physical examination, a 2 cm-sized mass was palpated directly under the right nipple, and, with squeezing, bloody discharge developed in a single duct of the left nipple. There was no palpable mass in the left breast, and axillary lymph nodes were not palpable. Physical examination of external genitalia revealed a unilateral undescended testis on the left side. Synchronous bilateral breast cancer was diagnosed using mammography, ultrasonography, and core-needle biopsy. Histopathological examination revealed invasive ductal carcinoma in the right breast and ductal carcinoma in situ in the left breast. Bilateral total mastectomy, sentinel lymph node biopsy, and excision of accessory breasts in the axilla were performed.

    The differential diagnosis of bilateral parotid gland enlargement in children includes infectious, inflammatory, and neoplastic disorders. We present the case of a 13-year-old male who presented with a 5-week history of bilateral parotid swelling. On exam, both parotid glands were nontender, smooth, and diffusely enlarged. He had slightly elevated inflammatory markers, but other lab results were normal. A neck CT revealed symmetric enlargement of the parotid, submandibular, and sublingual glands. A chest CT revealed scattered peripheral pulmonary nodules and bilateral hilar adenopathy. A parotid gland biopsy showed multiple noncaseating granulomas with multinucleated giant cells surrounded by lymphocytes, consistent with the diagnosis of sarcoidosis. Special stains for acid-fast and fungal organisms were negative. Using this illustrative case, we discuss the differential diagnosis of bilateral salivary gland enlargement in children and review the etiology, diagnosis, clinical manifestations, and treatment of pediatric sarcoidosis.

    2017-04-01

    A 30-year-old woman presented to our outpatient department with complaints of pain and swelling in bilateral infrapatellar regions and a discharging sinus in the right knee over the duration of one year. Radiographs showed lytic regions in bilateral patellae. Samples sent from material curetted from sinus yielded no organism but histopathology reported granulomatous inflammation. Following a fresh magnetic resonance imaging (MRI) scan that revealed the infrapatellar pad of fat communicating with the patellar lesions, an exploration and evacuation was done. Material sent revealed epithelioid cell granulomas with caseous necrosis consistent with tuberculosis (TB). The patient was put on first line anti-tubercular treatment (ATT) and has responded favourably with healing of sinus and patellar lesions. Bilateral infrapatellar bursitis is not rare. However patellar TB as a cause for OMIT is not a common diagnosis. A bilateral patellar involvement has not been reported in literature to the best of our knowledge.

    Results. A patient with rheumatoid arthritis presented with bilateral PUK following a 2-month history of ocular discomfort and redness. His systemic prednisolone (PDN and methotrexate (MTX were increased and, despite an initial favorable response, bilateral recurrent corneal perforations ensued. Both eyes underwent cyanoacrylate glue repair, amniotic membrane transplantation (AMT, and penetrating keratoplasty (PKP. Recurrence of the disease and bilateral perforations of the second PKP in both eyes prompted administration of intravenous infliximab immediately after the fourth PKP. The disease activity rapidly settled in both eyes, and at eighteen-month followup, after 12 infliximab infusions, the PUK remains quiescent with no further graft thinning or perforation. Conclusion. Infliximab can be used to arrest the progression of severe bilateral rheumatoid PUK in cases that are refractory to conventional treatment.

    2016-01-01

    Immediately sequential bilateral cataract surgery (ISBCS) is currently a "hot topic" in ophthalmology. There are well-documented advantages in terms of quicker visual rehabilitation and reduced costs. The risk of bilateral simultaneous endophthalmitis and bilateral blindness is now recognized to be minuscule with the advent of intracameral antibiotics and modern management of endophthalmitis. Refractive surprises are rare for normal eyes and with the use of optical biometry. Where a general anesthetic is indicated for cataract surgery, the risk of death from a second anesthetic is much higher than the risk of blindness. A widely recognized protocol from the International Society of Bilateral Cataract Surgeons needs to be adhered to if surgeons wish to start practicing ISBCS.

Contrary to unilateral cochlear implantation, however, little is known about the effect of bilateral cochlear implantation on tinnitus. To investigate tinnitus outcomes 1 year after bilateral cochlear implantation. Secondarily, to compare tinnitus outcomes between simultaneous and sequential bilateral cochlear implantation and to investigate long-term follow-up (3 years). This study is a secondary analysis as part of a multicenter randomized controlled trial. Thirty-eight postlingually deafened adults were included in the original trial, in which the presence of tinnitus was not an inclusion criterion. All participants received cochlear implants (CIs) because of profound hearing loss. Nineteen participants received bilateral CIs simultaneously and 19 participants received bilateral CIs sequentially with an inter-implant interval of 2 years. The prevalence and severity of tinnitus before and after simultaneous and sequential bilateral cochlear implantation were measured preoperatively and each year after implantation with the Tinnitus Handicap Inventory (THI) and Tinnitus Questionnaire (TQ). The prevalence of preoperative tinnitus was 42% (16/38). One year after bilateral implantation, there was a median difference of -8 (inter-quartile range (IQR): -28 to 4) in THI score and -9 (IQR: -17 to -9) in TQ score in the participants with preoperative tinnitus. Induction of tinnitus occurred in five participants, all in the simultaneous group, in the year after bilateral implantation. Although the preoperative and also the postoperative median THI and TQ scores were higher in the simultaneous group, the median difference scores were equal in both groups. In the simultaneous group, tinnitus scores fluctuated in the 3 years after implantation. In the sequential group, four patients had an additional benefit of the second CI: a total
