    2015-01-01

    Este artículo intenta contestar tres preguntas. Sobre el pasado: ¿Por qué no existió una epidemiología precolombina? Sobre el presente: ¿Cuáles son los orígenes de la epidemiología moderna, incluyendo sus raíces sudamericanas? Y sobre el futuro, escogí un título surrealista para enfatizar el hecho que estoy consciente de que es siempre delicado hacer predicciones: ¿Por qué fenómenos complejos son los “objetos oscuros del deseo” epidemiológico?

    -ray tube current) for each individual core section accordingly in order to obtain suitable XRF spectra. As a consequence, it is necessary to harmonise the acquired element profiles when constructing composite element stratigraphies in order to avoid distinct steps in the XRF-counts of consecutive sections measured with different instrument settings. In this contribution we describe the procedures that were used to harmonise the XRF-scanning data and present first results of the resulting element stratigraphies. As a terminal lake, the sedimentary record of Laguna Potrok Aike is well suited to trace temporal changes in the hydrological cycle. Subaerial and subaquatic terraces evidence large lake level variations of +21 m to -35 m during Holocene and Late Glacial periods. Changes in lake level have been previously reconstructed by variations in the TIC percentages and the XRF Ca-counts in the sedimentary record. However, while the element profile of Ca is controlled by the proportion of authigenically precipitated calcite in the lake during Holocene and Late Glacial times this seems to be different during the earlier periods of the Pleistocene. Hence, XRF Ca-counts in this older intervall, which represents more than 80% of the sediment thickness recovered during the PASADO drilling campaign, seem to be controlled by different mechanisms.

    El incremento universal de la prevalencia de obesidad en niños y adolescentes durante las últimas décadas, junto con la evidencia creciente de que el establecimiento de obesidad en etapas precoces de la vida está asociado con un incremento de la prevalencia de comorbilidades y del riesgo de muerte prematura, con gran repercusión económica en los sistemas sanitarios de los países occidentales, ha impulsado la investigación en este área. Estos estudios han remarcado la importante actividad endocrina del tejido adiposo, ejercida por medio de la síntesis y secreción de un gran número de péptidos y citoquinas, denominados adipoquinas. En esta revisión se resume el estado actual de los conocimientos, así como los estudios más relevantes, en relación con la dinámica de secreción de las principales adipoquinas en niños, centrándose en el control de la homeostasis energética, regulación metabólica (fundamentalmente, metabolismo de los hidratos de carbono) e inflamación. Asímismo, se analizan las particularidades de la síntesis, secreción y acciones de las adipoquinas desde el nacimiento hasta la adolescencia, reseñando el efecto que, sobre ellas, ejerce la instauración de la obesidad.

    Laguna Potrok Aike, located in the South-Patagonian province of Santa Cruz (52°58'S, 70°23'W), was formed by a volcanic (maar) eruption in the late Quaternary Pali Aike Volcanic Field several hundred thousand years ago. This archive holds a unique record of paleoclimatic and paleoecological variability from a region sensitive to variations in southern hemispheric wind and pressure systems, which provide a significant cornerstone for the understanding of the entire global climate system. Moreover, Laguna Potrok Aike is close to many active volcanoes allowing a better understanding of the history of volcanism in the Pali Aike Volcanic Field as well as in the Andean mountain chain, the latter located in a distance of less than 150 km to the west. Finally, Patagonia is the source region of eolian dust blown from the South American continent into the South Atlantic and onto the Antarctic ice sheet. The currently ongoing global climate change, the thread of volcanic hazards as well as of regional dust storms are of increasing socio-economic relevance and thus challenging scientific themes that are tackled for southernmost South America with an interdisciplinary research approach in the framework of the ICDP-funded "Potrok Aike Maar Lake Sediment Archive Drilling Project" (PASADO). Using the GLAD800 drilling platform seven holes were drilled in the southern spring of 2008. A total of 510 m of lacustrine sediments were recovered by an international scientific team from the central 100 m deep basin with an excellent core recovery rate of 94.4%. The reference profile with a composite depth of 106 m consists of undisturbed laminated and sand-layered lacustrine silts with an increasing number of coarse gravel layers, turbidites and homogenites with depth. Below 80 m composite depth two mass-movement deposits (10 m and 5 m in thickness) are recorded. These deposits show tilted and distorted layers as well as nodules of fine-grained sediments and randomly distributed gravel

  14. Making your presentation fun: creative presentation techniques

    SciTech Connect

    KEENEN,MARTHA JANE

    2000-05-18

    What possesses someone to volunteer and go through hoops and red tape to make a presentation at a conference? For that matter, why does anyone ever present anything to anyone? Actually, presentations are a fact of life and there are many reasons for doing a presentation and doing it well. New and existing staff need training and orientation to the way things are done here. Handing all of them a manual and hoping they read it is pretty much a waste of paper. On the other hand, an effective, entertaining and upbeat presentation on the relevant topics is more likely to stick with those people. They will even have a name and face to remember and seek out when they have an issue on or with that topic. This can be a very effective beginning for networking with new peers. The presenter is seen as knowledgeable, as a source of information on company topics and possibly evaluated as a potential mentor or future manager. Project staff and/or peers benefit from clear, concise, presentations of topical knowledge. This is one way that a group working on various aspects of the same project or program can stay in touch and in step with each other. Most importantly, presentations may be the best or only door into the minds (and budgets) of management and customers. These presentations are a wonderful opportunity to address legal and compliance issues, budget, staffing, and services. Here is a chance, maybe the only one, to demonstrate and explain the wonderfulness of a program and the benefit they get by using the services offered most effectively. An interactive presentation on legal and compliance issues can be an effective tool in helping customers and/or management make good risk management decisions.

The presentations range from specific and general content relating to stellar evolution and variable stars to specific activities for a workshop environment. A presentation—even with a general topic—that works for high school students will not work for educators, Science Olympiad teams, or the general public. Each audience is unique and requires a different approach. The current environment necessitates presentations that are captivating for a younger generation that is embedded in a highly visual and sound-bite world of social media, twitter and U-Tube, and mobile devices. For educators, presentations and workshops for themselves and their students must support the Next Generation Science Standards (NGSS), the Common Core Content Standards, and the Science Technology, Engineering and Mathematics (STEM) initiative. Current best practices for developing relevant and engaging powerpoint presentations to deliver information to a variety of targeted audiences will be presented along with several examples.

    PubMed

    Bandyopadhyay, Mousumi Roy; Besra, Mrinal; Dutta, Somasree; Sarkar, Somnath

    2016-01-01

    Dermatofibroma is a common benign fibrohistiocytic tumor and its diagnosis is easy when it presents classical clinicopathological features. However, a dermatofibroma may show a wide variety of clinicopathological variants and, therefore, the diagnosis may be difficult. The typical dermatofibroma generally occurs as a single or multiple firm reddish-brown nodules. We report here two atypical presentations of dermatofibroma - Atrophic dermatofibroma and keloidal presentation of dermatofibroma. Clinical dermal atrophy is a common phenomenon in dermatofibromas as demonstrated by the dimpling on lateral pressure. However, this feature is exaggerated in the atrophic variant of dermatofibroma. Atrophic dermatofibroma is defined by dermal atrophy of more than 50% of the lesion apart from the usual features of common dermatofibroma. The keloidal variant of dermatofibroma should not be overlooked as a simple keloid. The findings of keloidal change in dermatofibromas may support that trauma is a possible cause of dermatofibroma.

    2015-09-01

    Preeclampsia is a pregnancy-related syndrome, which still represents one of the major causes of maternal-fetal mortality and morbidity. Diagnosis can be made difficult due to the complexity of the disorder and its wide spectrum of clinical manifestations. In order to provide an efficient diagnostic tool to the clinician, medical societies regularly rethink the definition criteria. However, there are still clinical presentations of preeclampsia that escape the frame of the definition. The present review will address atypical forms of preeclampsia, such as preeclampsia without proteinuria, normotensive preeclampsia, preeclampsia before 20 weeks of gestation and post-partum preeclampsia.

    Teratocarcinosarcoma (TCS), an aggressive and extremely rare neoplasm, usually presents as a nasal or paranasal mass. TCS can have intracranial or dural extension from a nasal mass. We found only two instances in the literature that described this lesion as primarily manifesting as an intracranial mass while arising from a primary nasal focus. We describe a patient who had a predominantly frontal-lobe TCS without any symptoms of a primary nasal mass. The gross surgical appearance was a glistening, slimy, firm white mucoid lesion, in contrast to the friable, necrotic and tan-colored lesion usually described. We report a patient with a rare intracranial TCS, and focus on the differential diagnoses of intracranial tumors. Neuropathologists and neurosurgeons should be aware of this mode of presentation for an accurate diagnosis and a well-targeted therapeutic approach.

    Hindering and obfuscating psychiatric scholarship about the father's role, whether he is present or absent, are several widespread notions and practices--including conceptual, assumptive, attitudinal, methodologic and technical matters. Discussed are eleven barriers to research: patriarchal ideology, preference for studying individual and dyad instead of family systems, preference for considering adults not children, overly rigid definition of parental roles, choosing not longitudinal but one-time cross-sectional study, reasoning about linear cause and effect, focus on attitudes not overt behavior, failure to control for adequate number of variables, neglect of adequate sampling procedures, confusing correlation with causation and an overemphasis on obvious pathology. The father, present or absent, may be salient or insignificant in the life of a child. If salient, the father's role may promote health and growth or may be largely pathogenic. The conclusion holds that an irreducible family unit may consist of only one pair: caretaker/child. PMID:6529713

    Tuberculosis (TB) is less common in developed countries; however, the incidence of TB—especially resistant strains—is on the rise worldwide. Cases of TB manifesting as urologic complications are rare in the United States. Urologists should be aware of this potential manifestation, especially in patients who have recently immigrated to the United States or have traveled abroad for prolonged periods. Two cases are presented here to illustrate this entity. PMID:27222648

    A 44-year-old woman, with a background of heart, lung and renal transplantation secondary to cystic fibrosis and type 1 diabetes, presented with tachycardia, hyperglycaemia, nausea and vomiting. She was initially managed for diabetic ketoacidosis with severe dehydration. However, persistent episodic hypertension and tachycardia led the investigating team to identify significantly raised urinary metanephrines and a left-sided adrenal mass; Iodine-123-meta-iodobenzylguanidine single photon emission computer tomography scan (MIBG SPECT/CT) showed avid uptake of tracer, confirming a left-sided phaeochromocytoma. She was started on medical management and is awaiting an elective laparoscopic procedure. This case describes the presentation of a unilateral phaeochromocytoma as ketoacidosis in a patient with type 1 diabetes with no other apparent precipitant. This highlights the metabolic counter-regulatory effect of excess catecholamines in addition to the inotropic/chronotropic effects that are associated with this adrenal tumour. Recognition of atypical signs and symptoms may point towards an atypical precipitant of diabetic ketoacidosis-a medical emergency presenting to front-line clinicians. PMID:27166010

    Many experimental issues presented here must be resolved before we can really understand unimolecular rectification. Nevertheless, at the University of Alabama six unimolecular rectifiers have been studied (Fig. 1, 1- 6). Langmuir-Blodgett (LB) or Langmuir-Schaefer (LS) monolayer films of these molecules show asymmetric electrical conductivity between Au and Al electrodes. When the films are very compact (LS of 4, LB of 5), and if there is finite intramolecular charge transfer (ICT, or intervalence transfer, IVT), then the electrical behavior persists for many cycles of measurement.

    This slide presentation reviews the projects which the author engaged in during an internship at Johnson Space Center. Project 1 was involved with Stochastic Resonance (SR). Stochastic resonance is a phenomenon in which the response of a non-linear system to a weak input signal is optimized by the presence of a particular non-zero level of noise. The goal of this project was to develop a countermeasure for sensorimotor disturbances that are experienced after long duration space flight. The second project was a pilot study that was to examine how adaptation to a novel functional task was affected by postural disturbance.

    Schools are key to achieving the goal of producing 20% of the nation's electricity demand. Most significantly, schools are training the scientists, technicians, businesspeople, decisionmakers, and teachers of the future. What students learn and believe about wind energy will impact the United States' ability to create markets and policy, develop and improve technology, finance and implement projects, and create change in all of our public and private institutions. In the nearer term, school districts have large facility costs, electrical loads, and utility costs. They are always in search of ways to reduce costs or obtain revenue to improve educational programs. Schools value teaching about the science and technology of renewable energy. They are important opinion leaders, particularly in rural communities. And their financial structures are quite different from other institutions (funding, incentives, restrictions, etc.). Learning objectives: The presentation will use case studies, project experience, and discussion with the audience to convey the current status of wind energy applications and education in U.S. schools and understanding of the elements that create a successful school wind energy project. The presentation will provide attendees with a background in the current level of knowledge and generate discussion on several themes.

    Medical practice leadership teams, often consisting primarily of physicians with limited financial backgrounds, must make important business decisions and continuously monitor practice operations. In order to competently perform this duty, they need financial reports that are relevant and easy to understand. This article explores financial reporting and decision-making in a physician practice. It discusses reports and tools, such as ratios, graphs, and comparisons, that practices typically include in their reports. Because profitability and cash flow are often the most important financial considerations for physician practices, reports should generally focus on the impact of various activities and potential decisions upon these concerns. This article also provides communication tips for both those presenting practice financial information and those making the decisions. By communicating effectively, these leaders can best use financial information to improve decision-making and maximize financial performance.

    Angiocardiography is defined as an X-ray procedure which uses an intravascularly injected contrast material for visualization of the internal anatomy of the heart and great vessels. Past and present efforts in angiocardiography technology and methodology are reviewed, with special emphasis on qualitative and quantitative measurements of heart and vessel geometry. One of the more recent applications of angiographic image analysis has been for pattern recognition of margin motions over a cardiac cycle, termed contourography. Angiocardiography will continue to serve, as it has served in the past, as the principal standard of reference for calibration and/or comparison of newer methods for determining volume or dimensional change, depending on further technologic advances in X-ray equipment and means for displaying computer-processed information.

    Apprehension about oral communication, or public speaking is rated as the number one fear among most individuals. Developing skill in, and comfort with, public speaking is important whether we are presenting oral reports and proposals, responding to questions, or training co-workers. Effective speakers are able to communicate information in a way that stimulates interest, helps the audience to understand and remember, and influences attitudes and behaviours. Many of us think that effective speakers are born rather than made. In truth most successful speakers work hard and invest a great deal of time and effort in to improving their speaking capabilities. Effective public speaking is a learned skill and activity that requires lots of practice. Like other learned skills, having a strategy with clear action steps can help you achieve your goal.

    RESRAD was one of the multimedia models selected by the US Nuclear Regulatory Commission (NRC) to include in its workshop on radiation dose modeling and demonstration of compliance with the radiological criteria for license termination. This paper is a summary of the presentation made at the workshop and focuses on the 10 questions the NRC distributed to all participants prior to the workshop. The code selection criteria, which were solicited by the NRC, for demonstrating compliance with the license termination rule are also included. Among the RESRAD family of codes, RESRAD and RESRAD-BUILD are designed for evaluating radiological contamination in soils and in buildings. Many documents have been published to support the use of these codes. This paper focuses on these two codes. The pathways considered, the databases and parameters used, quality control and quality assurance, benchmarking, verification and validation of these codes, and capabilities as well as limitations of these codes are discussed in detail.

    This image of sulfate and water ice deposits in the Olympia Undae region of Mars was taken by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) at 2213 UTC on October 2, 2006 (6:13 p.m. EDT) near 81.6 degrees north latitude, 188.9 degrees east longitude. CRISM's image was taken in 544 colors covering 0.36-3.92 micrometers, and shows features as small as 20 meters (66 feet) across.

    Olympia Undae is a large dune field that stretches some 1,100 kilometers (684 miles) across the northern polar region of Mars, just south of the ice cap. The region holds a vast expanse of complex, shifting dunes and is best described as a sand sea or erg similar to the Sahara.

    The two images above provide interesting clues into Mars' history by revealing the planet's wet past and frozen present. The left image is an infrared, false-color image that reveals dark-colored dunes overlying a lighter substrate. Spectral data from CRISM and its sister instrument OMEGA suggest similar compositions of these dunes and the dark basal, or lowermost, unit of the north polar layered deposits. HIRISE images revealed cross-bedding (crossed layers that are oriented at a different angle to the main layer) in this dark unit. On Earth, cross-bedded sediments can form in both windy and watery environments. The dark polar basal unit on Mars is interpreted as a sand sheet underlying and pre-dating the ice, and now being eroded to dunes by the Martian winds.

    The mineralogy of the Olympia Undae region holds a record of past water. CRISM spectral data (right image) shows that the darker dunes are rich in polyhydrated sulfate (sulfates with more than one water molecule incorporated into each molecule of the mineral). The mineral gypsum is a polyhydrated sulfate, and the most likely constituent in these dunes. The gypsum probably formed by evaporation of ancient, saline water or by aqueous alteration of the silicate portion of the dune material. Areas shaded in red are cover by

    This symposium was devoted to the consideration of Dr. Mary Libbey's treatment of a 22-year-old woman. The unfolding of the analysand's symbiotic attachment to her mother, the devastating sequelae of her having been the stable center of a pathological family that devoted itself to the care of a severely handicapped sibling, and her immersion in unresolved mourning form the center of this richly detailed and carefully reported case study. In addition, four verbatim sessions are reported, one from each year of the first two years of treatment, and two from the third year of treatment. Dr. Epstein's discussion, praising Dr. Libbey's therapeutic skill, makes note of the issues in the patient's family of origin that served to prepare her to feel endangered in the treatment. Dr. Epstein's view is that the analyst has created an analytic situation that, because it is minimally impinging, allows the patient to become increasingly aware of her unmet needs in a way that is tolerable and minimally "destabilizing to the symbiotically based organization of her internal self and object world." In the climate of safety created in the treatment, the patient can begin to complete the work of mourning for her sister, friend, and aunt, a process of mourning that would be impossible in the context of her nuclear family, centered as it is on a mother who cannot tolerate separation. Limit-setting in the treatment is seen to be reassuring to the patient, facilitating as it does the analyst's commitment to maintaining the integrity of the analytic situation. Dr. Schafer's discussion, while in agreement with Dr. Epstein in recognizing the excellence of the presentation and the sensitivity and hard work that had gone into both the treatment and the clinical presentation, included some specific and focused observations about the transference and countertransference situations prevailing in this treatment and also some suggestions for creating a more consistently safe analytic atmosphere for

The current life expectancy of the satellite is 10 years. Since the launch, Space Imaging Inc. (the owner of the satellite) supplied IKONOS imagery to users in many vertical markets, such as: agriculture, defense, oil & gas and telecommunications. This oral presentation will give comprehensive information about IKONOS and the future: * Block II, the successor of IKONOS. Space Imaging expects to launch in 2004 a new high-resolution satellite, ensuring both continuity and (for some years) a tandem operation with IKONOS, greatly improving the availability of imagery. * Space Imaging affiliates. IKONOS imagery collected, processed and sold by regional affiliates. These regional affiliates are strategically located around the world, like Japan Space Imaging (Tokyo), Space Imaging Middle East (Dubai) and Space Imaging Eurasia (Ankara, Turkey). * Technical briefing IKONOS. IKONOS (compared to other commercial high-resolution satellites) has superior collection capabilities. Due to, the higher orbit altitude, local reception of the imagery, bi-directional scanning and the high agility of the satellite, is the IKONOS satellite capable to collect the imagery relative quickly.

    The use of plasmonic effects over a broad range of electromagnetic spectrum has been a challenge over the first few decades of research due to limited number of available materials. Recently, the efforts in the area has been concentrated on identifying and examining new material classes as the building blocks for optical technologies over a broader electromagnetic spectrum. Transition metal nitrides attract attention as plasmonic materials in the visible and infrared spectral regions with optical properties resembling gold. As refractory materials, nitrides can withstand heat induced physical phenomena as well as aggressive chemical environment. Adjustable dielectric permittivity of plasmonic nitrides allow fine tuning of optical properties for selected applications. In addition to favorable optical, physical and chemical properties; transition metal nitrides provide CMOS- and bio-compatibility. In this talk, novel designs and concepts based on refractory plasmonic materials for infrared applications will be presented. Additionally, light confinement at the nanoscale with refractory plasmonic antennas, spectral engineering of absorption and emission with metamaterials, and the use of colloidal solutions for a variety of applications will be discussed.

  17. Presentation of hepatocellular antigens

    2016-01-01

    The liver is an organ in which antigen-specific T-cell responses manifest a bias toward immune tolerance. This is clearly seen in the rejection of allogeneic liver transplants, and multiple other phenomena suggest that this effect is more general. These include tolerance toward antigens introduced via the portal vein, immune failure to several hepatotropic viruses, the lack of natural liver-stage immunity to malaria parasites, and the frequent metastasis of cancers to the liver. Here we review the mechanisms by which T cells engage with hepatocellular antigens, the context in which such encounters occur, and the mechanisms that act to suppress a full T-cell response. While many mechanisms play a role, we will argue that two important processes are the constraints on the cross-presentation of hepatocellular antigens, and the induction of negative feedback inhibition driven by interferons. The constant exposure of the liver to microbial products from the intestine may drive innate immunity, rendering the local environment unfavorable for specific T-cell responses through this mechanism. Nevertheless, tolerance toward hepatocellular antigens is not monolithic and under specific circumstances allows both effective immunity and immunopathology. PMID:26924525

The origin and the total number of all antibiotics and applied antibiotics in the practice, as well as the bioactive microbial metabolites (antibiotics) in other therapeutical, non-antibiotic fields (including agriculture) are also reviewed. The author discusses main problems, such as increasing (poly)resistance, virulence of pathogens and the non-scientific factors (such as a decline of research efforts and their sociological, economic, financial and regulatory reasons). A short summary of the history of Hungarian antibiotic research is also provided. The author briefly discusses the prospects in the future and the general advantages of the natural products over synthetic compounds. It is concluded that new approaches for the investigation of the unlimited possibilities of the living world are necessary. The discovery of new types or simply neglected (micro)organisms and their biosynthetic capabilities, the introduction of new biotechnological and genetic methods (genomics, metagenom, genome mining) are absolutely required in the future.

    The phase-out of CFC's and other ozone depleting chemicals has prompted industries to re-evaluate their present methods of cleaning. It has become necessary to find effective substitutes for their processes as well as to meet the new cleaning challenges of improved levels of cleanliness and to satisfy concerns about environmental impact of any alternative selected. One of the most popular alternatives being selected is aqueous cleaning. This method offers an alternative for removal of flux, grease/oil, buffing compound, particulates and other soils while minimizing environmental impact. What I will show are methods that can be employed in an aqueous cleaning system that will make it environmentally friendly, relatively simple to maintain and capable of yielding an even higher quality of cleanliness than previously obtained. I will also explore several drying techniques available for these systems and other alternatives along with recent improvements made in this technology. When considering any type of cleaning system, a number of variables should be determined before selecting the basic configuration. Some of these variables are: (1) Soil or contaminants being removed from your parts; (2) The level of cleanliness required; (3) The environmental considerations of your area; (4) Maintenance requirements; and (5) Operating costs.

  20. Spectrophotometry: Past and Present

    I describe the rise of optical region spectrophotometry in the 1960's and 1970's when it achieved a status as a major tool in stellar research through its decline and near demise at present. With absolutely calibrated fluxes and Balmer profiles usually of H-gamma, astronomers used model atmospheres predictions to find both the effective temperatures and surface gravities of many stars. Spectrophotometry as I knew it was photometrically calibrated low dispersion spectroscopy with a typical resolution of order 25 A. A typical data set consists of 10 to 15 values covering most of the optical spectral region. The strengths and shortcomings of the rotating grating scanners are discussed. The accomplishments achieved using spectrophotometric data, which were obtained with instruments using photomultipliers, are reviewed. Extensions to other spectral regions are noted and attempts to use observations from space to calibrate the optical region will be discussed. There are two steps to fully calibrate flux data. The first requires the calibration of the fluxes of one or more standard stars against sources calibrated absolutely in a laboratory. The use of Vega as the primary standard has been both a blessing as it is so bright and a curse especially as modeling it correctly requires treating it as a fast rotating star seen nearly pole-on. At best its calibration has errors of about 1%. The other step is to apply extinction corrections for the Earth's atmosphere and then calibrate the fluxes using the fluxes of standard stars. Now the ASTRA Spectrophotometer promises a revitalization of the use and availability of optical flux data. Its design specifications included solutions to the problems of past optical spectrophotometric instruments.

  1. Indian aerosols: present status.

    PubMed

    Mitra, A P; Sharma, C

    2002-12-01

    This article presents the status of aerosols in India based on the research activities undertaken during last few decades in this region. Programs, like International Geophysical Year (IGY), Monsoon Experiment (MONEX), Indian Middle Atmospheric Program (IMAP) and recently conducted Indian Ocean Experiment (INDOEX), have thrown new lights on the role of aerosols in global change. INDOEX has proved that the effects of aerosols are no longer confined to the local levels but extend at regional as well as global scales due to occurrence of long range transportation of aerosols from source regions along with wind trajectories. The loading of aerosols in the atmosphere is on rising due to energy intensive activities for developmental processes and other anthropogenic activities. One of the significant observation of INDOEX is the presence of high concentrations of carbonaceous aerosols in the near persistent winter time haze layer over tropical Indian Ocean which have probably been emitted from the burning of fossil-fuels and biofuels in the source region. These have significant bearing on the radiative forcing in the region and, therefore, have potential to alter monsoon and hydrological cycles. In general, the SPM concentrations have been found to be on higher sides in ambient atmosphere in many Indian cities but the NOx concentrations have been found to be on lower side. Even in the haze layer over Indian Ocean and surrounding areas, the NOx concentrations have been reported to be low which is not conducive of O3 formation in the haze/smog layer. The acid rain problem does not seem to exist at the moment in India because of the presence of neutralizing soil dust in the atmosphere. But the high particulate concentrations in most of the cities' atmosphere in India are of concern as it can cause deteriorated health conditions. PMID:12492171

  2. Indian aerosols: present status.

    PubMed

    Mitra, A P; Sharma, C

    2002-12-01

    This article presents the status of aerosols in India based on the research activities undertaken during last few decades in this region. Programs, like International Geophysical Year (IGY), Monsoon Experiment (MONEX), Indian Middle Atmospheric Program (IMAP) and recently conducted Indian Ocean Experiment (INDOEX), have thrown new lights on the role of aerosols in global change. INDOEX has proved that the effects of aerosols are no longer confined to the local levels but extend at regional as well as global scales due to occurrence of long range transportation of aerosols from source regions along with wind trajectories. The loading of aerosols in the atmosphere is on rising due to energy intensive activities for developmental processes and other anthropogenic activities. One of the significant observation of INDOEX is the presence of high concentrations of carbonaceous aerosols in the near persistent winter time haze layer over tropical Indian Ocean which have probably been emitted from the burning of fossil-fuels and biofuels in the source region. These have significant bearing on the radiative forcing in the region and, therefore, have potential to alter monsoon and hydrological cycles. In general, the SPM concentrations have been found to be on higher sides in ambient atmosphere in many Indian cities but the NOx concentrations have been found to be on lower side. Even in the haze layer over Indian Ocean and surrounding areas, the NOx concentrations have been reported to be low which is not conducive of O3 formation in the haze/smog layer. The acid rain problem does not seem to exist at the moment in India because of the presence of neutralizing soil dust in the atmosphere. But the high particulate concentrations in most of the cities' atmosphere in India are of concern as it can cause deteriorated health conditions.

    2016-01-01

    Data visualization research focuses on data exploration and analysis, yet the vast majority of visualizations people see were created for a different purpose: presentation. Whether we are talking about charts showing data to help make a presenter's point, data visuals created to accompany a news story, or the ubiquitous infographics, many more people consume charts than make them. Traditional visualization techniques treat presentation as an afterthought, but are there techniques uniquely suited to data presentation but not necessarily ideal for exploration and analysis? This article focuses on presentation-oriented techniques, considering their usefulness for presentation first and any other purposes as secondary.

    2013-07-01

    To highlight the difference in symptoms, clinical features and management of an intralingual thyroglossal cyst from a classical thyroglossal cyst. We present here the case of a 10 year old boy, who presented to us with the chief complaint of difficulty in speech for 2 years. A marble shaped swelling was seen on the base of the tongue. It was diagnosed as an intralingual thyroglossal cyst. He underwent a Sistrunk operation and the cyst was removed from the base of the tongue. Literature search revealed the rarity of this intralingual thyroglossal cyst, its atypical presentation and difference in way of management. A case report and review of literature regarding this unusual unusual entity is presented. An intralingual thyroglossal cyst is the rarest form of a thyroglossal cyst, and differs from a classical thyroglossal cyst totally in presentation and management. PMID:24427642

    Abstract Introduction: Leiomyoma of the bladder is a rare tumor arising from the submucosa. Most patients with bladder leiomyoma may present with urinary frequency or obstructive urinary symptoms. However, there are a few cases of bladder leiomyoma coexisting with uterine leiomyoma presenting as dyspareunia. We herein report an unusual case of coexisting bladder leiomyoma and uterine leiomyoma presenting as dyspareunia. Case presentation: A 44-year-old Asian female presented to urologist and complained that she had experienced dyspareunia over the preceding several months. A pelvic ultrasonography revealed a mass lesion located in the trigone of urinary bladder. The mass lesion was confirmed on contrast-enhanced computed tomography (CT). The CT scan also revealed a lobulated and enlarged uterus consistent with uterine leiomyoma. Then, the biopsies were then taken with a transurethral resection (TUR) loop and these biopsies showed a benign proliferation of smooth muscle in a connective tissue stroma suggestive of bladder leiomyoma. An open local excision of bladder leiomyoma and hysteromyomectomy were performed successfully. Histological examination confirmed bladder leiomyoma coexisting with uterine leiomyoma. Conclusion: This case highlights a rare presentation of bladder leiomyoma, dyspareunia, as the chief symptom in a patient who had coexisting uterine leiomyoma. Bladder leiomyomas coexisting with uterine leiomyomas are rare and can present with a wide spectrum of complaints including without symptoms, irritative symptoms, obstructive symptoms, or even dyspareunia.

    SciTech Connect

    Papp, A.L. III; Blattner, M.M.

    1994-05-16

    The centralized audio presentation manager addresses the problems which occur when multiple programs running simultaneously attempt to use the audio output of a computer system. Time dependence of sound means that certain auditory messages must be scheduled simultaneously, which can lead to perceptual problems due to psychoacoustic phenomena. Furthermore, the combination of speech and nonspeech audio is examined; each presents its own problems of perceptibility in an acoustic environment composed of multiple auditory streams. The centralized audio presentation manager receives abstract parameterized message requests from the currently running programs, and attempts to create and present a sonic representation in the most perceptible manner through the use of a theoretically and empirically designed rule set.

    2014-01-01

    Acute myocardial infarction (AMI) is usually seen in the setting of atherosclerosis and its associated risk factors. Myocardial infarction in the young poses a particular challenge, as the disease is less likely, due to atherosclerosis. We report the case of a 37-year-old female patient who presented with ST segment elevation anterolateral AMI. The only abnormality on routine blood investigation was raised hemoglobin and hematocrit. After further testing, she was diagnosed according to the World Health Organization (WHO) criteria with polycythemia vera. This case illustrates the importance of recognizing polycythemia vera as an important cause of thrombosis, which can present initially as AMI, and to emphasize the early recognition of the disease in order to initiate appropriate management strategies.

    Leishmaniasis or kala-azar is a protozoan disease that can present as cutaneous, mucocutaneous, visceral, and disseminated disease. In India, it is usually localized in distinct areas of Bihar, Jharkhand, West Bengal, and parts of Eastern Uttar Pradesh. Visceral leishmaniasis (VL) involves the visceral organs, mainly the liver, the spleen and bone marrow. VL is characterized by prolonged fever, massive splenomegaly, weight loss, progressive anemia, pancytopenia, and hypergammaglobulinemia, and can be complicated by serious infections. In most of the patient the diagnosis is made on bone marrow biopsy or splenic aspirate. We hereby present an unusual case of kala-azar in a 52-year-old patient non-resident of endemic area presenting with pyrexia of unknown origin, in whom bone marrow biopsy was negative for Leishmanin Donovan (LD) bodies, and diagnosis was made by liver biopsy in which LD bodies were seen.

    Topological information has proven very valuable in the analysis of scientific data. An important challenge that remains is presenting this highly abstract information in a way that it is comprehensible even if one does not have an in-depth background in topology. Furthermore, it is often desirable to combine the structural insight gained by topological analysis with complementary information, such as geometric information. We present an overview over methods that use metaphors to make topological information more accessible to non-expert users, and we demonstrate their applicability to a range of scientific data sets. With the increasingly complex output of exascale simulations, the importance of having effective means of providing a comprehensible, abstract overview over data will grow. The techniques that we present will serve as an important foundation for this purpose.

    2015-01-01

    DRESS syndrome (Drug Rash with Eosinophilia and Systemic Symptoms) is a potentially life-threatening syndrome, which reflects a serious hypersensitivity reaction to drugs, presenting by generalized skin rash, fever, eosinophilia, atypical lymphocytosis, and internal organ involvement. Herein a 21-month old male infant with DRESS and Encephalopathy syndrome is presented who complicated after phenobarbital usage that persisted due to phenytoin cream usage. The case received phenobarbital after a seizure disorder presented as "status epilepticus". He developed drug eruption, fever, hepatosplenomegaly, increased liver enzymes, encephalopathy and progressive loss of consciousness with extensive hyperintense white matter lesions in brain MRI. After discontinuation of phenobarbital and phenytoin, all symptoms were resolved, while brain MRI became normal after two months. To our best knowledge, this is the first reported case that developed leukoencephalopathy along with DRESS syndrome. PMID:27411428

    2015-01-01

    Hemophilia A is a X-linked hereditary condition that lead to decreased factor VIII activity, occurs mainly in males. Decreased factor VIII activity leads to increased risk of bleeding events. During neonatal period, diagnosis is made after post-partum bleeding complication or unexpected bleeding after medical procedures. Subgaleal hemorrhage during neonatal period is a rare, severe extracranial bleeding with high mortality and usually related to traumatic labor or coagulation disorders. Subgaleal hemorrhage complications result from massive bleeding. We present a neonate with unremarkable family history and uneventful pregnancy with a vaginal delivery with no instrumentation, presenting with severe subgaleal bleeding at 52 hours of life. Aggressive support measures were implemented and bleeding managed. The unexpected bleeding lead to a coagulation study and the diagnosis of severe hemophilia A. There were no known sequelae. This case shows a rare hemophilia presentation reflecting the importance of coagulation studies when faced with unexplained severe bleeding. PMID:26734126

    1980-12-01

    The presence of fructose, glucose, sucrose, maltose, and isomaltose in commercial tobacco products was identified and quantitated. Gas-liquid chromatographic studies showed that these five types of sugar were present in the water-soluble extracts of pouch and plug chewing tobacco, yet only fructose and glucose were found in extracts of snuff and unprocessed natural tobaccos. The amount of sucrose present in pouch chewing tobacco was twice that in plug chewing tobacco. No detectable amount of sucrose was found in snuff or unprocessed natural tobaccos. The content of maltose and isomaltose was much less than the content of fructose, glucose, or sucrose. All unprocessed natural tobacco leaves studied as controls contained low amounts of fructose and glucose, and no detectable amounts of sucrose, maltose, or isomaltose. The larger amounts of fructose and glucose, and the additional sucrose, maltose, and isomaltose present in pouch and plug chewing tobaccos are probably added during the manufacturing process.

    Acne rosacea is one of the most common diagnoses seen in the clinical dermatologic practice. The classic presentation of rosacea, acneiform papules, and pustules on a background of telangiectasia, is often easily identified by primary care physicians, patients, or their similarly afflicted friends or family members. However, rosacea actually represents a spectrum of disease from chronic skin hypersensitivity and flushing to rhinophyma. Although the pathogenesis of rosacea remains unknown, it is important to understand its various presentations and possible etiologies prior to developing individualized treatment protocols.

    Neuroblastoma is a malignant tumor arising from nerve tissue that accounts for approximately 15 percent of pediatric cancer fatalities. Primary tumors most commonly arise in sympathetic nervous tissue of the abdomen and metastasize to the bone marrow, liver, and lymph nodes. This case report depicts a 3-year-old girl who presented with a recurring fever, runny nose, and a positive test for rhinovirus suggesting a simple case of the common cold. Further investigation, however, revealed stage 4 neuroblastoma. This patient experience emphasizes the importance of having a high level of suspicion to rule out more serious underlying pathology in a seemingly unremarkable patient presentation. PMID:27491101

    Eales, Philip; Wayne, Andrew; Tildsley, Kevin M.; Wilkinson, Tim; Prieto, Diego Fernandez

    2013-12-01

    Earth observation data are now readily available at a range of scales and becoming increasingly familiar to the general public. Observations built up over several decades enable us to show long-term change and tell increasingly complex stories about the Earth and other planets. Data visualisation and computer graphics can help present these stories to a non-specialist public audience. In addition to high visual quality and clear design, we have found it useful to present data within its geographical and scientific context, in natural colour, in a realistic and immersive environment, using familiar visual and physical metaphors. The internet increasingly allows direct communication with the public and this places renewed emphasis on basics such as good story-telling. Examples are shown of work in television, print and digital media, and from ESA's Earth observation and planetary exploration programmes.

  15. Atypical presentation of Wilson disease.

    2011-08-01

    A 15-year-old Caucasian female on human chorionic gonadotropin (HCG) diet presented with fever, cholestasis, coagulopathy, hemolytic anemia, and acute renal dysfunction. Imaging of the biliary system and liver were normal. She responded to intravenous antibiotics, vitamin K and blood transfusions but experienced relapse upon discontinuation of antibiotics. She had remission with reinstitution of antibiotics. Liver biopsy revealed pronounced bile ductular reaction, bridging fibrosis, and hepatocytic anisocytosis and anisonucleosis with degenerative enlarged eosinophilic hepatocytes, suggestive of Wilson disease. Diagnosis of Wilson disease was further established based on the low serum ceruloplasmin, increased urinary and hepatic copper and presence of Kayser-Fleischer rings. The multisystem involvement of the liver, kidney, blood, and brain are consistent with Wilson disease; however, the clinical presentation of cholangitis and reversible coagulopathy is uncommon, and may result from concurrent acute cholangitis and/or the HCG diet regimen the patient was on.

    Conjugates of biotin with the decamer of glutamic acid (glu(sub 10)) and the trimer of D,L-2-amino-5-phosphonovaleric acid (I) have been synthesized, and it has been shown that they mediate the binding of avidin to hydroxylapatite. In a similar way a conjugate of methotrexate with glu(sub 10) mediates the binding of dihydrofolate reductase to the mineral. The presentation of ligands on the hydroxylapatite component of bone may find applications in clinical medicine.

    Although wheezing is one of the most common symptoms and physical findings in asthma, other causes of wheezing should be kept in mind: vocal cord dysfunction, postnasal drip syndrome, chronic obstructive pulmonary disease, bronchiectasis, and non-pulmonary diseases, like heart failure and pulmonary edema. Here, we present a case of severe mitral stenosis with pulmonary edema treated for resistant asthma. If asthma is difficult to control, other etiologies of wheezing, including cardiac disease, should be taken into consideration during diagnosis. PMID:26999914

  2. Sound and computer information presentation

    SciTech Connect

    Bly, S

    1982-03-01

    This thesis examines the use of sound to present data. Computer graphics currently offers a vast array of techniques for communicating data to analysts. Graphics is limited, however, by the number of dimensions that can be perceived at one time, by the types of data that lend themselves to visual representation, and by the necessary eye focus on the output. Sound offers an enhancement and an alternative to graphic tools. Multivariate, logarithmic, and time-varying data provide examples for aural representation. For each of these three types of data, the thesis suggests a method of encoding the information into sound and presents various applications. Data values were mapped to sound characteristics such as pitch and volume so that information was presented as sets or sequences of notes. In all cases, the resulting sounds conveyed information in a manner consistent with prior knowledge of the data. Experiments showed that sound does convey information accurately and that sound can enhance graphic presentations. Subjects were tested on their ability to distinguish between two sources of test items. In the first phase of the experiments, subjects discriminated between two 6-dimensional data sets represented in sound. In the second phase of the experiment, 75 subjects were selected and assigned to one of three groups. The first group of 25 heard test items, the second group saw test items, and the third group both heard and saw the test items. The average percentage correct was 64.5% for the sound-only group, 62% for the graphics-only group, and 69% for the sound and graphics group. In the third phase, additional experiments focused on the mapping between data values and sound characteristics and on the training methods.

    Background Brucellosis is one of the important multi-organ zoonotic infectious diseases. The forms of the clinical course of brucellosis in humans are acute, sub-acute and chronic. Objectives The present study aimed to retrospectively analyze the clinical characteristics and complications in the clinical forms of human brucellosis in Iran. Patients and Methods The population included 957 patients admitted in the infectious diseases clinic affiliated to Babol University of Medical Sciences, Babol, Iran, within the past two decades. Data for the patients were obtained and documented in questionnaires. Patients were divided into three groups according to their history, symptoms and clinical presentation time: acute (0 - 2 months), sub-acute (3 - 12 months), and chronic (> 1 year). Results Most of the patients (73.8%) were in the acute stages of brucellosis, 22.6% had sub-acute brucellosis and 3.7% had chronic brucellosis. The most frequently observed symptoms were arthralgia (71%), sweating (66.7%), fever (57.2%) and backache (39.3%). The most common complication was arthritis (13.2%) in this study. Conclusions This infection was observed with a diversity of clinical manifestations. Therefore, diagnostic difficulty because of the various clinical presentations and the way to find undiagnosed complications should be investigated in the differential diagnosis of other diseases.

    Giving a Grand Rounds presentation provides the hospice and palliative medicine subspecialist with the occasion to participate in a time-honored and respected event. It remains an opportunity to promote the discipline, support institutional culture change, and favorably influence the attitudes, knowledge, skills, and performance of colleagues. For those pursuing academic careers, it also is a chance to establish academic currency and develop teaching and presentation skills. In most academic settings, the format of Grand Rounds has shifted over time from a patient and problem-based discussion to a didactic, topic-focused lecture. A body of literature questions the value of this shift toward a more passive learner. Limited evidence prevents a definitive answer but many advocate for the integration of more interactive methods to improve the effectiveness of Grand Rounds. This article provides a flexible framework to guide those preparing to give a Grand Rounds and those teaching and supporting others to do so. To do this well, adult learning principles must be thoughtfully incorporated into a presentation style and method appropriate to the venue. The approach emphasizes learner-centeredness, interactive strategies, and evaluation. Room for creativity exists at every step and can add enjoyment and challenge along the way. PMID:21155643

    As the demands of scientific research and application for specimens increase rapidly, biobanks in China have been springing up over the recent years. This paper summarizes Chinese biobanks through investigation and survey on operative, managerial, ethical conditions and challenges of biobanks. At present, hospitals and research institutes in China set up and operate most of the biobanks, collecting human specimens to support clinical and scientific research. With the development of bio-industry and arrival of the big data era, biobanks need not only collect and store human and non-human specimens but also to manage the big data associated with these specimens.

    Neuromodulation has wide ranging potential applications in replacing impaired neural function (prosthetics), as a novel form of medical treatment (therapy), and as a tool for investigating neurons and neural function (research). Voltage and current controlled electrical neural stimulation (ENS) are methods that have already been widely applied in both neuroscience and clinical practice for neuroprosthetics. However, there are numerous alternative methods of stimulating or inhibiting neurons. This paper reviews the state-of-the-art in ENS as well as alternative neuromodulation techniques—presenting the operational concepts, technical implementation and limitations—in order to inform system design choices.

    Background. Tetanus is an acute disease caused by a neurotoxin produced by Clostridium tetani. Tetanus immunization has been available since the late 1930s but sporadic cases still occur, usually in incompletely vaccinated or unvaccinated individuals. Case Report. An elderly previously vaccinated female contracted tetanus following foot injury. Clinically she presented with meningitis causing diagnostic and therapeutic delays. Why Should Physician Be Aware of This? Even in developed countries the differential diagnosis of meningitis, especially in the elderly, should include tetanus. Treatment in intensive care unit is required. General population might benefit from vaccine boosters and education on this potentially fatal disease. PMID:25789186

    Diabetic myonecrosis is a frequently unrecognized complication of longstanding and poorly controlled diabetes mellitus. The clinical presentation is swelling, pain, and tenderness of the involved muscle, most commonly the thigh muscles. Management consists of conservative measures including analgesia and rest. Short-term prognosis is good, but long-term prognosis is poor with most patients dying within 5 years. Failure to properly identify this condition will expose the patient to aggressive measures that could result in increased morbidity. To our knowledge this is the first case reported in which there was involvement of multiple muscle groups including upper and lower limbs. PMID:23862080

    2009-01-01

    A set of extensions of the Satellite Orbit Analysis Program (SOAP) enables simultaneous and/or sequential presentation of information from multiple sources. SOAP is used in the aerospace community as a means of collaborative visualization and analysis of data on planned spacecraft missions. The following definitions of terms also describe the display modalities of SOAP as now extended: In SOAP terminology, View signifies an animated three-dimensional (3D) scene, two-dimensional still image, plot of numerical data, or any other visible display derived from a computational simulation or other data source; a) "Viewport" signifies a rectangular portion of a computer-display window containing a view; b) "Palette" signifies a collection of one or more viewports configured for simultaneous (split-screen) display in the same window; c) "Slide" signifies a palette with a beginning and ending time and an animation time step; and d) "Presentation" signifies a prescribed sequence of slides. For example, multiple 3D views from different locations can be crafted for simultaneous display and combined with numerical plots and other representations of data for both qualitative and quantitative analysis. The resulting sets of views can be temporally sequenced to convey visual impressions of a sequence of events for a planned mission.

    Professor David Southwood (ESA Director of Science), Dr Arvind Parmar (Integral's Acting Project Scientist), and the Principal Investigators will be presenting Integral’s first ground-breaking images and results at a press conference on 18 December at ESA Headquarters in Paris, France. Since its launch on 17 October, scientists have manoeuvred Integral into its operational orbit, thoroughly tested their communications link, and verified the spacecraft's response to their commands. They have also been fine-tuning the instruments by observing the famous black hole, Cygnus X-1. "We have beautiful gamma-ray images and spectra of the sky to show", says Arvind Parmar. Astronomers use spectra to analyse the energy of the radiation that they observe. Integral's results promise to be very special because it has already captured one of the most elusive events in the cosmos - a gamma-ray burst. Gamma-ray bursts are titanic explosions of varying duration that occur about twice daily. Scientists think that collapsing stars in the very distant Universe cause these mysterious, tremendous explosions. The fascinating and thought-provoking results from this observation will be presented at the press conference. Media representatives wishing to attend are kindly requested to complete the attached accreditation form and return it, preferably by fax, to the ESA Media Relations Service in Paris (Fax : +33(0)1.53.69.7690).

    Teratology is the science that studies the causes, mechanisms, and patterns of abnormal development. The authors present an updated overview of the most important milestones and stages of the development of modern teratology. Development of knowledge and society led to the recognition that causes of congenital developmental disorders (CDDs) might be caused by various mechanical effects, foetal diseases, and retarded or arrested development of the embryo and foetus. Based on the analysis of the historical development of hypotheses and theories representing a decisive contribution to this field, we present a survey of the six Wilson's fundamental principles of teratology. The aim of observing these principles is to get insight into developmental relations and to understand mechanisms of action on the level of cell populations (elementary morphogenetic processes), tissues and organs. It is important to realise that any negative intervention into the normal course of these processes, either on genetic or non-genetic basis, inevitably leads to a sequence of subsequent changes resulting in CDDs. Moreover, the classical toxicologic monotonic dose-response paradigm recently has been challenged by the so-called "low dose-hypothesis", particularly in the case of endocrine active substances. These include some pesticides, dioxins, polychlorobiphenyls (PCBs), and bisphenol A. Despite modern approaches of molecular biology and genetics, along with top diagnostic techniques, we are still not able to identify the actual cause in more than 65 to 70% of all congenital defects classified as having an unknown etiology. Today CDDs include any birth defect, either morphological, biochemical, or behavioural.

    The Configuration Aerodynamics (CA) element of the High Speed Research (HSR) program is managed by a joint NASA and Industry team, referred to as the Technology Integration Development (ITD) team. This team is responsible for the development of a broad range of technologies for improved aerodynamic performance and stability and control characteristics at subsonic to supersonic flight conditions. These objectives are pursued through the aggressive use of advanced experimental test techniques and state of the art computational methods. As the HSR program matures and transitions into the next phase the objectives of the Configuration Aerodynamics ITD are being refined to address the drag reduction needs and stability and control requirements of High Speed Civil Transport (HSCT) aircraft. In addition, the experimental and computational tools are being refined and improved to meet these challenges. The presentation will review the work performed within the Configuration Aerodynamics element in 1994 and 1995 and then discuss the plans for the 1996-1998 time period. The final portion of the presentation will review several observations of the HSR program and the design activity within Configuration Aerodynamics.

    Background Graphical displays of results allow researchers to summarise and communicate the key findings of their study. Diagnostic information should be presented in an easily interpretable way, which conveys both test characteristics (diagnostic accuracy) and the potential for use in clinical practice (predictive value). Methods We discuss the types of graphical display commonly encountered in primary diagnostic accuracy studies and systematic reviews of such studies, and systematically review the use of graphical displays in recent diagnostic primary studies and systematic reviews. Results We identified 57 primary studies and 49 systematic reviews. Fifty-six percent of primary studies and 53% of systematic reviews used graphical displays to present results. Dot-plot or box-and- whisker plots were the most commonly used graph in primary studies and were included in 22 (39%) studies. ROC plots were the most common type of plot included in systematic reviews and were included in 22 (45%) reviews. One primary study and five systematic reviews included a probability-modifying plot. Conclusion Graphical displays are currently underused in primary diagnostic accuracy studies and systematic reviews of such studies. Diagnostic accuracy studies need to include multiple types of graphic in order to provide both a detailed overview of the results (diagnostic accuracy) and to communicate information that can be used to inform clinical practice (predictive value). Work is required to improve graphical displays, to better communicate the utility of a test in clinical practice and the implications of test results for individual patients. PMID:18405357

    Metabolic dysfunction in hypoparathyroidism is an important cause of intracranial calcifications, which cause cognitive impairment depending on the calcified areas leading to difficulties in executing activities of daily living. We report a case of a 25-year-old man who presented with gradually decreasing organisational skills, memory problems and difficulty in carrying out daily activities. CT imaging of the brain showed extensive calcification in the basal ganglia and cerebral white matter. Comprehensive health-related quality of life and cognitive assessment revealed significant affliction in his activities of daily living along with impairment in recall memory, executive functions and verbal fluency. Owing to late diagnosis, chronicity of cognitive problems could not prevent him from discontinuing his college education. PMID:23709145

    1977-01-01

    A data set comprising 110 spreading rates, 78 transform fault azimuths and 142 earthquake slip vectors was inverted to yield a new instantaneous plate motion model, designated RM2. The mean averaging interval for the relative motion data was reduced to less than 3 My. A detailed comparison of RM2 with angular velocity vectors which best fit the data along individual plate boundaries indicates that RM2 performs close to optimally in most regions, with several notable exceptions. On the other hand, a previous estimate (RM1) failed to satisfy an extensive set of new data collected in the South Atlantic Ocean. It is shown that RM1 incorrectly predicts the plate kinematics in the South Atlantic because the presently available data are inconsistent with the plate geometry assumed in deriving RM1. It is demonstrated that this inconsistency can be remedied by postulating the existence of internal deformation with the Indian plate, although alternate explanations are possible.

    Adrenomyeloneuropathy (AMN), one of the variants of X-linked adrenoleukodystrophy (ALD), is inherited peroxisomal disorder associated with the accumulation of very long chain fatty acids (VLCFA). AMN is characterized primarily by involvements of long ascending and descending tracts of the spinal cord and peripheral neuropathy, which leads to spastic paraparesis and urinary and erectile dysfunction. We experienced the AMN case of a 33-year-old man presenting bilateral progressive spastic paraparesis, impotence and urge incontinence with primary adrenal failures, as confirmed by increased serum of VLCFA concentrations. Considering that somatosensory evoked potentials in posterior tibial nerve was the only abnormal finding in electrophysiologic findings when compared with the severe spastic gait pattern shown, it is necessary to follow up with electrophysiologic studies.

    The continuous electron beam accelerator facility and associated experimental equipment at Jefferson Lab comprise a unique facility for nuclear physics research whose upgrade is presently underway, with completion expected in 2017. The upgraded facility will accelerate electron beams to 11 GeV for experiments in the existing Halls A, B and C. In addition, a 12 GeV beam can be provided to a new experimental hall, Hall D, to generate a 9 GeV tagged photon beam. This upgrade will enable a new experimental program with substantial discovery potential to address important topics in hadronic, nuclear, and electroweak physics. Further in the future, it is envisioned that the Laboratory will evolve into an electron-ion colliding beam facility.

  5. Functional membranes. Present and future

    The present situation and the future development of the functional membrane are discussed. It is expected that functional membranes will play increasingly greater roles in the chemical industry of the coming decade. These membranes are formed from polymer films, liquid membranes or bilayer membranes. The two most important technologies based on the polymeric membrane are reverse osmosis and ion exchange. The liquid membrane is used for separation of ionic species; an extension of the solvent extraction process. By using appropriate ligands and ionophores, highly selective separations are realized. The active transport is made possible if the physical and chemical potentials are applied to the transport process. More advanced functional membranes may be designed on the basis of the synthetic bilayer membrane.

    The past year has marked the most devastating Ebola outbreak the world has ever witnessed, with over 28,000 cases and over 11,000 deaths. Ebola virus (EBOV) has now been around for almost 50 years. In this review, we discuss past and present outbreaks of EBOV and how those variants evolved over time. We explore and discuss selective pressures that drive the evolution of different Ebola variants, and how they may modify the efficacy of therapeutic treatments and vaccines currently being developed. Finally, given the unprecedented size and spread of the outbreak, as well as the extended period of replication in human hosts, specific attention is given to the 2014–2015 West African outbreak variant (Makona).

    2014-01-01

    Neurocysticercosis (NCC) is the most common helminthic infestation of the central nervous system (CNS) and a leading cause of acquired epilepsy worldwide. The common manifestations of NCC are seizures and headache. The NCC as a cause of pseudobulbar palsy is very unusual and not reported yet in the literature. A pseudobulbar palsy can occur in any disorder that causes bilateral corticobulbar disease. The common etiologies of pseudobulbar palsy are vascular, demyelinative, or motor neuron disease. We report a 38-year-old female patient who presented with partial seizures and pseudobulbar palsy. The MRI brain showed multiple small cysts with scolex in both the cerebral hemispheres and a giant intraparenchymal cyst. Our patient responded well to standard treatment of neurocysticercosis and antiepileptics. PMID:24741260

    Scurvy is a well-known disease of vitamin C deficiency that still occurs in industrialized countries. The clinical manifestations of follicular hyperkeratosis, perifollicular petechiae, corkscrew hairs, and easy bruising are due to defective collagen synthesis and can be mistaken for small vessel vasculitis. Populations at risk for development of scurvy include elderly patients, alcohol and drug users, individuals who follow restrictive diets or have eating disorders, patients with malabsorption, and individuals with mental illness. We report an acute case of scurvy presenting in the inpatient/hospital setting with clinical findings initially thought to represent vasculitis. A high index of suspicion for scurvy must be kept in the appropriate clinical context, and a thorough medical history and physical examination are vital to make the diagnosis.

    An overview of psychiatry during the last three decades as practised in a general teaching hospital is presented. Psychiatry as an academic subject has matured tremendously during this period. The empirical treatments of the 1950s and the 1960s which evoke nostalgic memories, have been replaced by modern methods of treatment. However, there is a need to exercise caution against the blind acceptance of new and sophisticated research findings in biological psychiatry. Inspite of the bright future facing psychiatry, the identity of psychiatry as a medical discipline must be preserved at all cost. Psychiatrists should also realise the dangers of gradual fractionation and impersonalisation which threatens the speciality, and makes all possible efforts to prevent this. PMID:21584054

  12. Integrons: Past, Present, and Future

    PubMed Central

    2014-01-01

    SUMMARY Integrons are versatile gene acquisition systems commonly found in bacterial genomes. They are ancient elements that are a hot spot for genomic complexity, generating phenotypic diversity and shaping adaptive responses. In recent times, they have had a major role in the acquisition, expression, and dissemination of antibiotic resistance genes. Assessing the ongoing threats posed by integrons requires an understanding of their origins and evolutionary history. This review examines the functions and activities of integrons before the antibiotic era. It shows how antibiotic use selected particular integrons from among the environmental pool of these elements, such that integrons carrying resistance genes are now present in the majority of Gram-negative pathogens. Finally, it examines the potential consequences of widespread pollution with the novel integrons that have been assembled via the agency of human antibiotic use and speculates on the potential uses of integrons as platforms for biotechnology.

    How is the present represented in the brain? This review introduces several theoretical and experimental issues regarding time perception, with special focus on the human visual system. Specifically, it addresses possible ways through which visual information can be processed to allow for the conscious experience of spatio-temporal local relations, object-based temporal localization, object duration, and mental time. We begin with a brief mention of isomorphism and its limitations, and from there we proceed to discuss low-level mechanisms for timing outer events. The concept of spatiotemporal receptive fields with biphasic temporal impulse response functions is introduced. Neurons with such receptive fields are believed to extract elementary information about spatial and temporal inclinations of light intensity. These visual primitives are later reconstructed in biologically meaningful ways to create each perceptual timeline in the brain. The precise mechanism by which each perceptual timeline is created remains unknown; however, for the purpose of this paper, we refer to it as "context", relative to which novel objects are to be spatiotemporally localized by using various cues. Localization involves estimation, including prediction and "postdiction" from currently available cues. As such, many aspects of the subjective present, such as "perceived timing", "subjective duration", and "mental clock" result from estimation and are thus prone to errors, leading often to time illusion. More than one perceptual timeline can exist and serve as an inner clock for multiple objects, multiple attributes, and even for multiple sensory modalities. Calibration across timelines is also a major issue; our ability to exercise flexible recalibration with short-term training or adaptation using salient time markers is briefly argued before ending the review.

    2010-01-01

    Background and aims Bilirubin is an orange-yellow tetrapyrrole produced from the breakdown of heme by mammals and some other vertebrates. Plants, algae and cyanobacteria synthesize molecules similar to bilirubin, including the protein-bound bilins and phytochromobilin which harvest or sense light. Recently, we discovered bilirubin in the arils of Strelitzia nicolai, the White Bird of Paradise Tree, which was the first example of this molecule in a higher plant. Subsequently, we identified bilirubin in both the arils and the flowers of Strelitzia reginae, the Bird of Paradise Flower. In the arils of both species, bilirubin is present as the primary pigment, and thus functions to produce colour. Previously, no tetrapyrroles were known to generate display colour in plants. We were therefore interested in determining whether bilirubin is broadly distributed in the plant kingdom and whether it contributes to colour in other species. Methodology In this paper, we use HPLC/UV and HPLC/UV/electrospray ionization-tandem mass spectrometry (HPLC/UV/ESI-MS/MS) to search for bilirubin in 10 species across diverse angiosperm lineages. Principal results Bilirubin was present in eight species from the orders Zingiberales, Arecales and Myrtales, but only contributed to colour in species within the Strelitziaceae. Conclusions The wide distribution of bilirubin in angiosperms indicates the need to re-assess some metabolic details of an important and universal biosynthetic pathway in plants, and further explore its evolutionary history and function. Although colour production was limited to the Strelitziaceae in this study, further sampling may indicate otherwise. PMID:22476078

    ASCENDS: Past,Present and Future by Berrien Moore III (University of Oklahoma) and Ken Jucks (NASA) with The ASCENDS Science Working Group The Active Sensing of CO2 Emissions over Nights,Days,and Seasons (ASCENDS) mission was recommended by the National Research Council's Decadal Survey,and it is considered the scientific and technological next step following Japan's Greenhouse gases Observing SATellite (GOSAT) and NASA's Orbiting Carbon Observatory (OCO).Space agencies are commitment to CO2 observations:GOSAT-2:Japan is proceeding with its development;OCO-2:NASA has launched it into the A-Train;TanSat:China's CO2 mission is in development,and CarbonSat is being considered by ESA.Using a laser,ASCENDS will make uninterrupted CO2 observations in high-latitudes,nighttime observations,and measurements in partly cloud conditions.ASCENDS expands the sampling of the atmosphere and may avoid some of the potential biases of passive systems.An issue for any mission is the linkage of observations to information regarding the subject of interest—in this case,surface fluxes of CO2.ASCENDS and the other low-Earth orbiting CO2 missions are difference from most missions in which the subject of interest is directly observed.In the case of these missions,the purpose of the atmospheric measurement is to determine surface fluxes that are distant from where the atmosphere is observed.This distinction between the subject observed and the subject of interest places added importance on the mission's observational requirements that governs the specifications of the mission and instrument.We discuss the challenge of establishing these mission requirements and present quantitative information on mapping observations with their uncertainties to information regarding terrestrial and oceanic surface fluxes of CO2.Results from the ASCENDS Science Working Group that the link measurement requirements to flux determination (or flux uncertainty reductions) are highlighted.We discuss modeling

    Respiratory obstruction and stridor in infants and children are not uncommon. A rare cause of these sometimes life-threatening symptoms is the congenital saccular cyst. Objectives: We present the case of a 5-year-old girl with a cervical tumor, which appeared after a laryngeal endoscopic surgery of a saccular cyst with two relapses and a particular local evolution of its recurrence through the cricothyroid membrane. Material and method: The patient data has been reviewed over the entire follow-up period and a thorough an analysis of her investigations and surgery was performed. Results: The unusual evolution of this case was marked by an atypical exteriorization – not found in the published literature. The surgical approach was external, by paramedian thyrotomy, with no further long-term recurrence. Conclusions: An accurate diagnosis of saccular cysts can be made with the help of medical history, by an endoscopic visualization of the lesion and by the CT-scan imaging of the cervical region. Sometimes, saccular cysts can extend beyond laryngeal limits, determining fluid-filled tumors in the cervical region. PMID:27453755

    A case is presented of a premature newborn of 27 weeks gestation and weighing 420 grams who was delivered as a result of a maternal pre-eclampsia and retarded intra-uterine growth. During the 125 days of hospitalisation, an individual care plan based on the Virginia Henderson model was devised and applied to both the child and her parents using NANDA diagnostics, interventions according to the NIC classification, and the expected results according to the NOC classification. The Marjory Gordon functional patterns were used for the initial assessment. By applying the pre-term newborn (PTNB) plan, all their needs were provided and were modified throughout the hospital stay, with new needs that were added to the established ones. These required a continuous assessment with the subsequent adapting of the care plan. Likewise, the care required by the parents varied from the initial grief due to the possible loss of their child to learning the alarm signs and the home care that their child would need. The child was finally discharged weighing 2900 grams and with normal neurological and psychomotor development, although with a lower weight appropriate to her age. Currently, at 2 years old, the child has a normal neurological and psychomotor development, but with weight and size lower than the P(3) percentile. She requires speech therapy treatment due to paralysis of the right vocal cord.

    The practice of neonatology in Israel debuted in the 1970s as local enterprises by individual hospitals that needed to provide sick and preterm newly born infants with up-to-date and effective care. Descriptions of research and advances in humane and gentle treatment during neonatal care for preterm infants and their families, as well as prevention of neonatal infections, follow-up of preterm infants and care of full-term infants are presented in this issue. The Israel National Very Low Birth Weight (VLBW) Infant database provides an excellent source of knowledge, which has led to multiple scientific publications. Recent international comparisons of the outcome of preterm VLBW infants, made possible by this unique database in Israel, has provided the neonatal community and the Ministry of Health with insights as to the differences in prognosis between Israel and other countries, especially among extremely low birth weight infants. At the border of viability, mortality in Israelis significantly higher than that reported in other countries and proactive steps undertaken to examine these differences and prompt correctional action should be pursued. The Israel Ministry of Health started positive initiatives and should ensure that their steps are implemented at the preterm infant's bedside. PMID:27012065

    Before the advent of direct acting antiviral agents (DAAs) ribavirin, associated to pegylated-interferon played a crucial role in the treatment of chronic hepatitis C, preventing relapses and breakthroughs. In the present era of new potent DAAs, a place is still devoted to the drug. Ribavirin associated with sofosbuvir alone is efficient in the treatment of most cases of G2 infected patients. All options currently available for the last difficult-to-treat cirrhotic G3 patients contain ribavirin. Reducing treatment duration to 12 wk in G1 or G4 cirrhotic compensated patients is feasible thanks to ribavirin. Retreating patients with acquired anti NS5A resistance-associated variants using ribavirin-based strategies could be useful. The addition of ribavirin with DAAs combinations however, leads to more frequent but mild adverse events especially in cirrhotic patients. Preliminary data with interferon-free second generation DAAs combinations without ribavirin suggest that future of the drug is jeopardized even in difficult-to-treat patients: The optimization of ribavirin dosage according to an early monitoring of blood levels has been suggested to be relevant in double therapy with peginterferon or sofosbuvir but not with very potent combinations of more than two DAAs.

    2006-10-01

    Nuclear power plants currently generate about 20% of US and 17% of world electricity, which makes nuclear the largest non-emitting energy source in current use. Concerns about global climate change have led to a remarkable transformation of attitudes towards nuclear energy. There remain key challenges that must be faced when considering expansion of its contribution. In summary they are: Economics, Safety, Waste Disposal, and Proliferation. Electricity from legacy fission plants is highly competitive with fossil, but perceived financial risks make the large capital cost fraction a key hurdle to new-construction, and costs of 2 per installed Watt electrical are currently considered only just economically attractive. Proliferation of nuclear-weapons-enabling technology is a major concern for global stability, in which fusion may have significant technical advantages over fission. But proliferation control requires a combination of both technical and political initiatives. The feasibility of supplying process heat or hydrogen from nuclear energy inspires additional research into novel reactor concepts and associated technologies. The presentation will lay out this overall context of the nuclear energy renaissance.

    Electrical, electronic and electro-mechanical components play an essential role in the functional performance, quality, life cycle and costs of space systems. Their standardisation, product specification, development, evaluation, qualification and procurement must be based on a coherent and efficient approach, paying due attention to present and prospective European space policies and must be commensurate with user needs, market developments and technology trends. The European Space Components Coordination (ESCC) is established with the objective of harmonising the efforts concerning the various aspects of EEE space components by ESA. European national and international public space organisations, the component manufacturers and the user industries. The goal of the ESCC is to improve the availability of strategic EEE space components with the required performance and at affordable costs for institutional and commercial space programmes. It is the objective of ESCC to achieve this goal by harmonising the resources and development efforts for space components in the ESA Member States and by providing a single and unified system for the standardisation, product specification, evaluation, qualification and procurement of European EEE space components and for the certification of components and component manufacturers.

    2016-01-01

    Big bang nucleosynthesis (BBN) describes the production of the lightest nuclides via a dynamic interplay among the four fundamental forces during the first seconds of cosmic time. A brief overview of the essentials of this physics is given, and new calculations presented of light-element abundances through 6Li and 7Li, with updated nuclear reactions and uncertainties including those in the neutron lifetime. Fits are provided for these results as a function of baryon density and of the number of neutrino flavors Nν. Recent developments are reviewed in BBN, particularly new, precision Planck cosmic microwave background (CMB) measurements that now probe the baryon density, helium content, and the effective number of degrees of freedom Neff. These measurements allow for a tight test of BBN and cosmology using CMB data alone. Our likelihood analysis convolves the 2015 Planck data chains with our BBN output and observational data. Adding astronomical measurements of light elements strengthens the power of BBN. A new determination of the primordial helium abundance is included in our likelihood analysis. New D/H observations are now more precise than the corresponding theoretical predictions and are consistent with the standard model and the Planck baryon density. Moreover, D/H now provides a tight measurement of Nν when combined with the CMB baryon density and provides a 2 σ upper limit Nν<3.2 . The new precision of the CMB and D/H observations together leaves D/H predictions as the largest source of uncertainties. Future improvement in BBN calculations will therefore rely on improved nuclear cross-section data. In contrast with D/H and 4He, 7Li predictions continue to disagree with observations, perhaps pointing to new physics. This paper concludes with a look at future directions including key nuclear reactions, astronomical observations, and theoretical issues.

    In healthy adults younger than 65 years the effectiveness of influenza vaccination is up to 90% for laboratory confirmed influenza, but is far less in elderly individuals over 65 years and those with comorbidities. However the vaccination in elderly people is effective in preventing complications of influenza infection: pneumonia, hospital admission and death from influenza or pneumonia. This effect is larger for elderly individuals living in nursing homes than in those living in the community. Recommendations at present include vaccination of all people over the age of 65, of high-risk groups, and of those who can transmit influenza to high-risk individuals (healthcare workers). Since 2005 it is recommended that people with occupational contact with wild or domestic birds should be vaccinated to reduce the risk of simultaneous infection with a human and an avian influenza virus. Influenza vaccination is considered to be safe: side effects are reversible within 1-2 days, severe complications are exceedingly rare. Most frequently inactivated vaccines are used, but in the USA there is also an attenuated live vaccine available. They all contain surface antigens of two influenza A strains and one influenza B strain. The world health organization (WHO) selects every year the strains to be included in the vaccine and the viruses are then grown on embryonated chicken eggs. This process requires detailed planning up to 6 months. Because a pandemic event cannot be predicted, this period is too long and there is an urgent need to develop techniques to reduce the vaccine production time and enhance its efficacy. Additionally, several researchers are exploring the possibility of generating a universal vaccine against influenza A virus that does not require reformulation on an annual basis.

    The tragedy of disappearing of Aral Sea is well known to the World. Before and after collapse of Soviet Union, a huge quantity of scientific and popular editions described with grief the situation around the Aral Sea. After the NIS states became independent, World Bank, UNDP, UNEP in proper competition with each other had provided some assessment of the situation through presentation of some small and medium grants, but after 2000, the local population remained alone with own problems. Although on the eyes of the present generation a unique transformation of great water body into deserts took place, the global scientific community did not find forces and financing for real and detail investigation of the processes accompanying the Sea shrinking and land formation. We should acknowledge and give big respect to NATO, later to German Government that through GTZ (now GIZ) - German International Collaboration Agency - and GFZ (Potzdam) paid attention to this area of environment crisis and organized scientific and protective design in the so-called Priaralie - the territory around the drying Sea and delta of the two rivers - Amudarya and Syrdarya. Thank to this assistance, the local specialists in collaboration with limited a number of foreign scientists (N.Aladin, P.Zavialov, Joop de Schutter, Hans Wilps, Hedi Oberhansli) organized significant works for detail socioeconomic, ecological and hydrological assessment situation in Priaralie and on the Aral sea coast. On this base, Ministry of Agriculture and Water resources of Uzbekistan and State Committee of Water resources of Kazakhstan developed a plan of rehabilitation of Amudarya and Syrdarya deltas and started implementation of these projects. If Kazakh water authority moved ahead in wetland restoration faster, a forestation of delta and drying bed of Aral Sea got big success in Uzbek territory. 244 thousands hectares of saxsaul and tamarix were planted for protection of the Priaralie.

  11. Ceres: Evolution and Present State

    Castillo-Rogez, J.; McCord, T.

    2007-08-01

    Introduction:We consider Ceres as a prototype for planetary evolution [1]. From thermal modeling by McCord and Sotin [2, 3, 4], Ceres was inferred to have differentiated into a rocky core of hydrated silicates, and an icy outer shell. Thomas et al. [5] confirmed such a model from direct observation of Ceres's shape from Hubble Space Telescope observations, and pervious occultation measurements. McCord and Sotin [4] also suggest that Ceres could have preserved a deep ocean, especially if ammonia or some other ice melting point depressant, such as salts, was incorporated during accretion. We continue to develop thermal modeling of Ceres, using increasingly sophisticated models and new observational information in order to match the observed shape. . In particular, we investigate the evolution of the core. Approach: Our models require the following initial input: initial planetesimal temperature (after [6]); composition; time of formation with respect to Calcium-Aluminum Inclusions (CAIs); and an internal heat profile after initial accretion. Modeling begins with a porous Ceres (after [7, 8]). The rock phase has the composition of an ordinary chondrite (after [9]). Short-lived radiogenic isotopes, including 26Al and 60Fe, have initial concentrations as measured by [10, 11]. Conductive thermal evolution is computed for one-dimensional models following the approach of [4] and [12]. The silicate core evolves through hydration, then dehydration and melting stages. Currently, hydrothermal cooling is not included in our algorithm. Model Results: Conditions were present for full differentiation of Ceres if accretion time t0-CAIs was less than 7 My and/or if ammonia was accreted. For times of formation t0-CAIs shorter than 2 My, the boiling point of water was reached within a few My after accretion, and may have led to major water loss.Under these conditions, hydrothermal activity was inevitable, and might still be taking place inside Ceres.

    of radiooptical trigger mechanism in formation of clouds and aerosol layers is weakening that has to result in decrease in cirrus clouds which cause net warming at high altitudes. Evidently as delicate physical mechanism as governing the rated of association and dissociation of cluster ions is able to affect only newly born optically thin clouds, which are for away from the stable cyclonic and anticyclonic formations. Optically thick clouds that produce a net cooling need by far greater energy and longer time for evolution than comparatively short burst of fluxes during solar flares and geomagnetic storms. Formation of thick low clouds to a considerable extent is determined by the magnitude of GCR fluxes. Weakening of the solar activity (which we have pointed out here) have led to the GCR increase. Moreover it is shown that there is a negative correlation between long-term GCR variations and surface air temperature changes. The GCR increase causes the growth of low cloudness and therefore produce mainly cooling effect on the mean surface air temperature. But it would be difficult to separate solar, geomagnetic and GCR effects which vary in a similar way and almost simultaneously. Thus it is shown in the present paper that during last years the main factors of solar variability influence on the weather and climate changes sign of trends in the direction that leads to the decrease of global mean surface air temperature. According to the recent analysis of meteorological data (Japan Meteorological Agency, 2008) the rate of global warming in 2008 appears to be slowing in comparison with the last third of XX century.

    2011-09-01

    Central Diabetes Insipidus mostly presents with polydipsia and polyuria but may also present with confusion, psychosis, seizure or coma. We present a case of Central Diabetes Insipidus presenting with manic symptoms. A 21 year old Indian male had Central Diabetes Insipidus, which was confirmed by water deprivation test. He presented to our hospital with full blown manic symptoms meeting the ICD 10 criteria. He was managed with intranasal Desmopressin, water restriction and Olanzapine. In contrary to routine psychiatric patients which may present with psychogenic polydipsia or Central Diabetes Insipidus patients presenting in delirium or psychosis, our case presents a unique example of Central Diabetes Insipidus presenting with manic symptoms. It hints about a relationship between a common pathway for Central Diabetes Insipidus and mood disorders which needs further research. Diencephalon has already been the focus of attention for several researchers but no concrete evidence is available yet. PMID:23051126

    Alopecia can be one of the many symptoms of secondary syphilis and the clinical presentations include essential syphilitic alopecia or symptomatic syphilitic alopecia. In this report, we present a case of a patient with essential syphilitic alopecia whose sole presenting symptom of syphilis was alopecia. Despite an initial negative rapid plasma reagin (RPR) test, he was ultimately found to have syphilis on scalp biopsy. His alopecia improved following treatment with benzathine penicillin. This presentation serves as a reminder to clinicians to be cognizant of alopecia as a presenting sign of syphilis. A review of the specificity and sensitivity of the typical tests used for the diagnosis is presented.

  1. Verbal evaluative conditioning with undetected US presentations.

    PubMed

    De Houwer, J; Baeyens, F; Eelen, P

    1994-07-01

    In evaluative conditioning research it has been shown that a neutral stimulus (CS) acquires the valence of a positive or negative stimulus (US) with which it is presented contingently. An experiment is reported in which it is examined whether evaluative shifts can also be observed in the complete absence of contingency-awareness. Neutral words were either followed by a briefly presented positive or negative word. Results showed that neutral words which were presented contingently with a positive word, were afterwards liked more than words which were paired with negative words. This result was obtained despite the fact that Ss were not aware of the presentation of the briefly presented USs.

    Carcinoid tumors are rarely known to metastasise to the brain. It is even more rare for such patients to present with symptoms related to metastases as the initial and only symptom. We present a case of a 60-year-old man who presented with hemiparesis and imaging features suggestive of brain tumor. He underwent surgery and the histopathology revealed metastatic malignant lesion of neuroendocrine origin. A subsequent work up for the primary was negative. Patient was treated with adjuvant radiotherapy. We present this case to highlight the pathophysiological features, workup and treatment options of this rare disease and discuss the methods of differentiating it from more common brain tumors.

    While learning a complex skill in science using a computer-based simulation, optimal timing of information presentation facilitates learning and enhances test performance. An optimal information presentation format is proposed: supportive information is presented before practising a skill, and procedural information is presented during practice. Four information presentation formats were compared in a factorial design with the factors timing of supportive information (before or during task practice) and timing of procedural information (before or during task practice). Eighty-eight third-year high school students (37 male, 51 female; mean age = 14 years, standard deviation = 0.52) participated in the experiment. Information searching behaviour and transfer test performance were studied. The information searching behaviour confirms the hypothesis. Findings on the transfer test are less clear due to a bottom effect.

  20. Intracellular events regulating cross-presentation

    PubMed Central

    Wagner, Claudia S.; Grotzke, Jeffrey E.; Cresswell, Peter

    2012-01-01

    Cross-presentation plays a fundamental role in the induction of CD8-T cell immunity. However, although more than three decades have passed since its discovery, surprisingly little is known about the exact mechanisms involved. Here we give an overview of the components involved at different stages of this process. First, antigens must be internalized into the cross-presenting cell. The involvement of different receptors, method of antigen uptake, and nature of the antigen can influence intracellular trafficking and access to the cross-presentation pathway. Once antigens access the endocytic system, different requirements for endosomal/phagosomal processing arise, such as proteolysis and reduction of disulfide bonds. The majority of cross-presented peptides are generated by proteasomal degradation. Therefore, antigens must cross a membrane barrier in a manner analogous to the fate of misfolded proteins in the endoplasmic reticulum (ER) that are retrotranslocated into the cytosol for degradation. Indeed, some components of the ER-associated degradation machinery have been implicated in cross-presentation. Further complicating the matter, endosomal and phagosomal compartments have been suggested as alternative sites to the ER for loading of peptides on major histocompatibility complex class I molecules. Finally, the antigen presenting cells involved, particularly dendritic cell subsets and their state of maturation, influence the efficiency of cross-presentation. PMID:22675326

    Oral leprosy, a granulomatous disease is classified under the term oro-facial granulomatosis which comprises a group of diseases characterized by noncaseating granulomas affecting the soft tissues of the oral and maxillofacial region. The most common clinical presentation of oro-facial granulomatous conditions is persistent swelling of one or both lips. Due to its rare incidence and clinical findings overlapping with other granulomatous conditions such as sarcoidosis, Crohn's disease, and cheilitis granulomatosa; it is practically difficult for a dental surgeon to easily diagnose this condition. This study presents a case of leprosy causing macrocheilia as the only clinical presentation and diagnosed initially as Miescher's cheilitis based on exclusion criteria. PMID:26604590

    2008-05-01

    REM sleep behaviour disorder (RBD) is a neurological condition well known to be associated with the synucleinopathies in middle-aged patients. However, there is much less data concerning its development, evolution, and association with other disorders in younger patients. We report two patients aged less than 33 years who presented with clinical and polysomnographical features of RBD, both of whom proved to have previously undiagnosed narcolepsy. Whilst the association of narcolepsy with RBD has been previously recognised, this is the first report of narcoleptic patients presenting with RBD. Narcolepsy should be included in the differential diagnosis of young patients presenting with abnormal behaviour during sleep compatible with RBD. PMID:18343568

    2016-01-01

    Mixed adenocarcinoid tumors are not uncommon neoplasms of appendix. The clinical presentation of these tumors is often similar to that of acute appendicitis or may present as asymptomatic. These tumors are found incidentally during histopathological examination of the resected appendix following appendectomy or other abdominal procedures. Mixed adenocarcinoids usually behave as adenocarcinomas with rapid metastasis, so prognosis depends upon how aggressive the tumor behaves. The present study reports a case of a 53-year-old male who presented with abdominal pain and fever for 1 day and underwent successful appendectomy and recovered later. Subsequently, a mixed adenocarcinoma with carcinoid features of the appendix was diagnosed by histopathological examination. Follow-up examination of the patient in 3 months revealed metastasis of carcinoma to the peritoneum with adenocarcinoma features.

    Gonococcus typically affects the mucosal surfaces but in rare cases can spread to bloodstream causing disseminated gonococcal infection (DGI). The usual presentation of DGI is rash, polyarthralgia, and tenosynovitis. We present the case of a 23-year-old female who presented to our hospital with pustular rash and tenosynovitis of hand and was sent home on Augmentin. Her symptoms worsened despite treatment and she presented back to the ED. On investigation, she was found to have DGI and was appropriately treated. DGI should be kept in mind in sexually active youngsters who have only one or two features of the classic triad of rash, tenosynovitis, and arthritis. Timely management and appropriate treatment of DGI is very important to avoid complications and morbidity. PMID:27406461

    Mumtaz, Seemal; Alkhuziem, Maha; Chow, Jennifer; Yen, Andrew; Lin, Grace; Harrell, James H; Thistlethwaite, Patricia A

    2015-09-01

    Tracheobronchial fibromas are very rare, locally-invasive tumors of the airways. Fewer than 30 cases have been reported within the English-speaking literature. Historically, these neoplasms have been diagnosed as isolated endobronchial masses, with affected patients presenting with wheezing, cough, stridor, hemoptysis, dyspnea, or pneumonia. We report the case of 39-year-old man with multiple, synchronous endobronchial fibromas causing unilobar emphysema. A computed tomographic scan and bronchoscopy with biopsy were performed preoperatively to diagnose these lesions in the orifices of the anterior segment and the lingula within the left upper lobe. The patient underwent successful video-assisted left upper lobectomy, without recurrence at 3 years. This is the first report of a synchronous presentation of multiple pulmonary endobronchial fibromas within the same patient and the first report of endobronchial fibroma presenting as unilobar air trapping. Recognition of the unusual presentation of this uncommon pathology can lead to timely intervention. PMID:26354646

    Symptoms and signs of the hypothyroidism vary in relation to the magnitude and acuteness of the thyroid hormone deficiency. The usual clinical features are constipation, fatigue, cold intolerance and weight gain. Rarely it can present with neurologic problems like reversible cerebellar ataxia, dementia, peripheral neuropathy, psychosis and coma. Hypothyroidism should be suspected in all cases of ataxia, as it is easily treatable. A 40 year-old male presented with the history facial puffiness, hoarseness of voice and gait-ataxia. Investigations revealed frank primary hypothyroidism. Anti-TPO antibody was positive. Thyroxine was started and patient improved completely within eight weeks. Hypothyroidism can present with ataxia as presenting feature. Hypothyroidism should be considered in all cases of cerebellar ataxia as it is a reversible cause of ataxia. PMID:26886095

    Prior research on false memories has shown that suggestibility is often reduced when the presentation rate is slowed enough to allow monitoring. We examined whether slowing presentation speed would reduce factual errors learned from fictional stories. Would subjects use the extra time to detect the errors in the stories, reducing reproduction of these errors on a later test? Surprisingly, slowing presentation speed increased the production of story errors on a later general knowledge test. Instructing the reader to mark whether each sentence contained an error, however, did decrease suggestibility. Readers appear to passively accept information presented in stories and need a constant reminder to monitor for errors. These results highlight differences between typical episodic false memories and illusions of knowledge (such as learning from fiction). Manipulations that reduce suggestibility for episodic false memories do not always reduce suggestibility for illusions of knowledge.

    Esophageal cancer most commonly presents with upper digestive symptoms such as dysphagia. Lymph nodes are among the most common metastatic sites of this type of cancer. We report the case of a 53-year-old man presenting with unusual sole presenting features of esophageal cancer. The patient sought medical attention for abdominal pain without dysphagia, which was first investigated with an abdominal computed tomography scan. A large abdominal mass was discovered on imaging. Biopsies of this mass were in keeping with esophageal squamous cell cancer. With this finding, gastroscopy was performed, confirming the presence of primary esophageal cancer. This is a rare presentation of esophageal cancer without upper gastrointestinal symptoms. This case reinforces the value of biopsy for any neoplastic mass, especially in a context of unusual symptoms. PMID:22679417

    1975-01-01

    The effect is presented of updating past airship designs using current materials and propulsion systems to determine new airship performance and productivity capabilities. New materials and power plants permit reductions in the empty weights and increases in the useful load capabilities of past airship designs. The increased useful load capability results in increased productivity for a given range, i.e., either increased payload at the same operating speed or increased operating speed for the same payload weight or combinations of both. Estimated investment costs and operating costs are presented to indicate the significant cost parameters in estimating transportation costs of payloads in cents per ton mile. Investment costs are presented considering production lots of 1, 10 and 100 units. Operating costs are presented considering flight speeds and ranges.

    Retroperitoneal lymphocele is one of the common complications following renal transplantation, and usually present with persistent lymphatic drain in immediate post transplant period or perigraft collection in post transplant routine ultrasound. In this case report, we present a renal transplant recipient who presented with acute urinary retention and right sided lower limb swelling mimicking deep vein thrombosis (DVT), due to a large lymphocele behind the bladder compressing bladder neck and common iliac vessels, approximately 2 months after renal transplant. Though lymphocele is not uncommon post transplant complication, the presentation of lymphocele after 2 months post transplant with pressure effect of this type is uncommon. In this case, pressure on common iliac vessels mimicking DVT and on bladder neck, leading to acute retention of urine and leading to hydronephrotic graft; which occurred in CNI (Cyclosporine) based regimen is extremely rare.

    An accurate method is needed for determining cell temperature when measuring CPV modules outdoors. It has been suggested that cell temperature can be calculated though a procedure that shutters sunlight to the cells while measuring the transients in open-circuit voltage (Voc) and heat sink temperature. This presentation documents application of this shutter procedure to multiple CPV modules at NREL. The challenges and limitations are presented along with an alternate approach to measuring CPV cell operating temperature.

    The incidence of hypothyroidism presenting with sigmoid volvulus, a phenomenon known as myxedema pseudovolvulus, is exceedingly rare. A male in his late thirties presented to our institution with a chief complaint of abdominal pain. The patient underwent CT scan, which was consistent with massive colonic dilatation with sigmoid volvulus. He was taken to the operating room for exploration and was found to have sigmoid volvulus and underwent a segmental resection. Postoperatively, the patient was newly diagnosed with severe hypothyroidism. PMID:27106615

    We report a 63-year old patient who presented to our care initially with a hypernasal voice followed by ataxia, ptosis, dysphonia, and paresthesias. The patient's history, physical examination, and additional tests led to a Miller Fisher syndrome (MFS) diagnosis. Palatal paralysis as an inaugurating manifestation of MFS is quite rare and requires special attention from neurologists and otolaryngologists. Although it may present as benign as an acute change in voice, early diagnosis and prompt management may prevent further complications. PMID:27609285

    Tuberculosis is caused by the Mycobacterium tuberculosis bacterium. Tuberculosis primarily affects the lungs. Patients mainly complain of cough, sputum, night sweating, weight loss, and fever. However, there may be cases of atypical presentations. Although aphthous mouth ulcers are mostly present in the oral cavity in primary tuberculosis patients, our literature search showed only one case report of pulmonary tuberculosis with oral aphthae. Here we report a case of a patient with pulmonary tuberculosis admitted to the hospital with the complaint of oral aphthae.

    Necrotizing sialometaplasia usually presents as a painless, deeply excavating ulcer and is considered in the differential diagnosis of large palatal ulcers along with mucoepidermoid carcinoma and adenoid cystic carcinoma. This case is presented to illustrate that the early signs and symptoms of necrotizing sialometaplasia may be swelling with a purulent exudate, diffuse, vague pain, and numbness. It also demonstrates the rapidity with which initial signs of healing become apparent. This latter clinically suggests a benign process.

    Restricted and repetitive behavior (RRB) is more pervasive, prevalent, frequent, and severe in individuals with autism spectrum disorders (ASDs) than in their typical peers. One subtype of RRB is restricted interests in items or activities, which is evident in the manner in which individuals engage with items (e.g., repetitious wheel spinning), the types of items or activities they select (e.g., preoccupation with a phone book), or the range of items or activities they select (i.e., narrow range of items). We sought to describe the relation between restricted interests and teacher presentation of items. Overall, we observed 5 teachers interacting with 2 pairs of students diagnosed with an ASD. Each pair included 1 student with restricted interests. During these observations, teachers were free to present any items from an array of 4 stimuli selected by experimenters. We recorded student responses to teacher presentation of items and analyzed the data to determine the relation between teacher presentation of items and the consequences for presentation provided by the students. Teacher presentation of items corresponded with differential responses provided by students with ASD, and those with restricted preferences experienced a narrower array of items.

    This study was conducted to investigate how the mode of stimulus presentation affects recall in the classroom environment. 289 undergraduates were randomly assigned to one of 7 experimental groups. All subjects were presented the same stimuli in one of 7 possible modes: (1) Printed Word, (2) Spoken Word, (3) Picture, (4) Printed Word + Spoken Word, (5) Picture + Spoken Word, (6) Picture + Printed Word, and (7) Printed Word, Picture + Spoken Word. 30 words, 6 from each of 5 categories, were presented to each group. A new stimulus was presented every 5 sec. Subjects were to recall (in writing) as many stimuli as possible in 5 min. regardless of order. One-way between groups analyses of variance were conducted on recall and cluster index scores. A significant main effect of mode of presentation showed that recall was best for the Picture or multimodal group (Printed Word, Picture + Spoken Word). Groups receiving only the spoken or printed word showed significantly poorer recall than the multimodal groups. No statistically significant differences between groups were found on the cluster index score. It appears that the simultaneous presentation of redundant stimuli in multiple modalities does support the multiple-resource hypothesis by displaying enhanced recall when information is available from multiple attentional resources.

    2014-01-01

    Polydactyly is a prevalent birth anomaly observed in the foot, and a number of classification systems have been suggested for this condition. Postaxial (fifth or little toe) polydactyly is the most common type. We encountered an exceedingly rare presentation of foot postaxial polydactyly that, to our inspection, had neither been previously classified nor described in published studies. In the present report, we have described an otherwise healthy 2-year-old female who had presented to our clinic with an isolated, extra little toe on her left foot. Foot radiographs revealed the presence of all 5 metatarsals; however, the fifth metatarsal was blocked and did not give rise to the fifth toe. Instead, the fifth (medial normal) and sixth (lateral extra) toes had originated from a single, separate accessory bud from the fourth metatarsal, and the main fourth metatarsal had given rise to the normal fourth toe. The lateral sixth toe was excised, and a periosteal sleeve of the excised extra toe was used for reconstruction of the lateral collateral ligament. We propose that this heretofore unmentioned presentation of postaxial polydactyly be added to the existing systems of classification of pedal polydactyly. A review of the published data pertaining to pedal polydactyly has also been presented.

    A description is given of user interface research aimed at bringing together multiple input and output modes in a way that handles mixed mode input (commands, menus, forms, natural language), interacts with a diverse collection of underlying software utilities in a uniform way, and presents the results through a combination of output modes including natural language text, maps, charts and graphs. The system, Integrated Interfaces, derives much of its ability to interact uniformly with the user and the underlying services and to build its presentations, from the information present in a central knowledge base. This knowledge base integrates models of the application domain (Navy ships in the Pacific region, in the current demonstration version); the structure of visual displays and their graphical features; the underlying services (data bases and expert systems); and interface functions. The emphasis is on a presentation planner that uses the knowledge base to produce multi-modal output. There has been a flurry of recent work in user interface management systems. (Several recent examples are listed in the references). Existing work is characterized by an attempt to relieve the software designer of the burden of handcrafting an interface for each application. The work has generally focused on intelligently handling input. This paper deals with the other end of the pipeline - presentations.

    2013-01-01

    Objective: The goal of this study was to examine the clinical presentation of chronic traumatic encephalopathy (CTE) in neuropathologically confirmed cases. Methods: Thirty-six adult male subjects were selected from all cases of neuropathologically confirmed CTE at the Boston University Center for the Study of Traumatic Encephalopathy brain bank. Subjects were all athletes, had no comorbid neurodegenerative or motor neuron disease, and had next-of-kin informants to provide retrospective reports of the subjects' histories and clinical presentations. These interviews were conducted blind to the subjects' neuropathologic findings. Results: A triad of cognitive, behavioral, and mood impairments was common overall, with cognitive deficits reported for almost all subjects. Three subjects were asymptomatic at the time of death. Consistent with earlier case reports of boxers, 2 relatively distinct clinical presentations emerged, with one group whose initial features developed at a younger age and involved behavioral and/or mood disturbance (n = 22), and another group whose initial presentation developed at an older age and involved cognitive impairment (n = 11). Conclusions: This suggests there are 2 major clinical presentations of CTE, one a behavior/mood variant and the other a cognitive variant. PMID:23966253

  10. Gesture Analysis for Astronomy Presentation Software

    NASA Astrophysics Data System (ADS)

    Robinson, Marc A.

    Astronomy presentation software in a planetarium setting provides a visually stimulating way to introduce varied scientific concepts, including computer science concepts, to a wide audience. However, the underlying computational complexity and opportunities for discussion are often overshadowed by the brilliance of the presentation itself. To bring this discussion back out into the open, a method needs to be developed to make the computer science applications more visible. This thesis introduces the GAAPS system, which endeavors to implement free-hand gesture-based control of astronomy presentation software, with the goal of providing that talking point to begin the discussion of computer science concepts in a planetarium setting. The GAAPS system incorporates gesture capture and analysis in a unique environment presenting unique challenges, and introduces a novel algorithm called a Bounding Box Tree to create and select features for this particular gesture data. This thesis also analyzes several different machine learning techniques to determine a well-suited technique for the classification of this particular data set, with an artificial neural network being chosen as the implemented algorithm. The results of this work will allow for the desired introduction of computer science discussion into the specific setting used, as well as provide for future work pertaining to gesture recognition with astronomy presentation software.

    Intradural clival chordomas are very rare, and only 29 cases have been reported to our knowledge. They arise purely intradurally without bone or dural involvement and may differ from classic clival chordomas in physiopathology and management. We present a 28-year-old woman who presented with intradural clival chordoma and tumoral bleeding. After initial gross macroscopic surgical resection, she presented with tumor recurrence after 2 years, again with intratumoral bleeding. Although usually considered to have a more favorable prognosis in comparison to typical chordomas, intradural chordomas appear to behave as typical chordomas. Intratumoral bleeding may be a sign of an aggressive lesion and risk of recurrence. We highlight the differential diagnosis of intrinsic posterior fossa bleeding, especially in young patients. Intradural chordomas may be underdiagnosed and incorrectly treated as other types of parenchymal hemorrhage.

    Human infection by Dicrocoelium dendriticum, a zoonotic liver fluke, is uncommon and soft tissue manifestation is extremely rare. The infection has no specific clinical signs or symptoms and diagnosis may be missed completely, thus treatment may be delayed. Diagnosis in humans is by identification of the eggs in the stool, while a living or dead fluke is rarely seen. The present report concerns the case of a 7-year-old child who presented with recurrent right flank subcutaneous nodules containing a live fluke on excision, and tissue histology showed characteristic brown operculated ova of D dendriticum. This is the first extraintestinal soft tissue presentation in such a setting. It is important to know the life cycle and natural habitat of this rare human parasite in order to make a correct diagnosis and institute early treatment in patients who have become infected.

    The innate capability to perceive three-dimensional stereo imagery has been exploited to present multidimensional meteorological data fields. Variations on an artificial stereo technique first discussed by Pichel et al. (1973) are used to display single and multispectral images in a vivid and easily assimilated manner. Examples of visible/infrared artificial stereo are given for Hurricane Allen and for severe thunderstorms on 10 April 1979. Three-dimensional output from a mesoscale model also is presented. The images may be viewed through the glasses inserted in the February 1981 issue of the Bulletin of the American Meteorological Society, with the red lens over the right eye. The images have been produced on the interactive Atmospheric and Oceanographic Information Processing System (AOIPS) at Goddard Space Flight Center. Stereo presentation is an important aid in understanding meteorological phenomena for operational weather forecasting, research case studies, and model simulations.

    Chikungunya fever is a vector borne virus that typically causes a self-limiting systemic illness with fever, skin rash and joint aches 2 weeks after infection. We present the case of a 69-year-old woman presenting with an acute unilateral optic neuropathy as a delayed complication of Chikungunya virus (CHIKV) infection contracted during a recent trip to the West Indies. She presented to our ophthalmology department with acute painless visual field loss in the right eye and a recent flu-like illness. She was found to have a right relative afferent pupillary defect (RAPD) with unilateral optic disc swelling. Serology confirmed recent CHIKV infection. Treatment with intravenous methylprednisolone was delayed while awaiting MRI scans and serology results. At 5-month follow-up, there was a persistent right RAPD and marked optic atrophy with a corresponding inferior scotoma in the visual field.

    Introduction. Tympanosclerosis is a commonly encountered entity within ENT clinics and primary care settings. Recognizing ear pathology is essential for correct management. Oftentimes the diagnosis is clear; however in certain cases further workup to rule out other more insidious disease processes is warranted. Case Report. We present a case of tympanosclerosis which presented as an ear mass without classic appearance of tympanosclerosis. Through imaging and biopsy the diagnosis of tympanosclerosis was made. The patient was treated surgically with good outcome. Discussion. Various ear pathologies, with different treatment algorithms, may present as clinically similar to one another. Differential diagnosis for this case included tympanosclerosis, cholesteatoma, or other middle ear masses. We review these entities and discuss their pathophysiology and implications on management.

  18. Does Presentation Order Impact Choice After Delay?

    PubMed

    Berger, Jonah

    2016-07-01

    Options are often presented incidentally in a sequence, but does serial position impact choice after delay, and if so, how? We address this question in a consequential real-world choice domain. Using 25 years of citation data, and a unique identification strategy, we examine the relationship between article order (i.e., position in a journal issue) and citation count. Results indicate that mere serial position affects the prominence that research achieves: Earlier-listed articles receive more citations. Furthermore, our identification strategy allows us to cast doubt on alternative explanations (i.e., editorial placement) and instead indicate that the effect is driven by psychological processes of attention and memory. These findings deepen the understanding of how presentation order impacts choice, suggest that subtle presentation factors can bias an important scientific metric, and shed light on how psychological processes shape collective outcomes.

    2014-01-01

    Systemic karyomegaly is a distinct disorder characterized by progressive renal failure and enlarged, bizarre renal tubular epithelial cells. We report the first case of systemic karyomegaly with primary pulmonary presentation and present the first detailed characterization of the karyomegalic cells in lung tissue. A 33-year-old woman was evaluated for chronic and progressive restrictive lung disease, ultimately necessitating single-lung transplantation. Her post-transplant course was marked by graft dysfunction, respiratory decline and renal failure culminating in her death 97 days post-transplant. At autopsy, karyomegalic cells were identified in her kidneys, prompting a careful examination of her native lung and other tissue. Karyomegalic cells were identified in the alveolar epithelium and airway walls. Viral studies were negative. DNA ploidy studies revealed an abnormal ploidy status of the karyomegalic cells. The identification and characterization of systemic karyomegaly with symptomatic lung involvement expands the differential diagnosis for relatively young patients presenting with interstitial lung disease.

    Artificial antigen presentation aims to accelerate the establishment of therapeutic cellular immunity. Artificial antigen-presenting cells (AAPCs) and their cell-free substitutes are designed to stimulate the expansion and acquisition of optimal therapeutic features of T cells before therapeutic infusion, without the need for autologous antigen-presenting cells. Compelling recent advances include fibroblast AAPCs that process antigens, magnetic beads that are antigen specific, novel T-cell costimulatory combinations, the augmentation of therapeutic potency of adoptively transferred T lymphocytes by interleukin-15, and the safe use of dendritic cell-derived exosomes pulsed with tumor antigen. Whereas the safety and potency of the various systems warrant further preclinical and clinical studies, these emerging technologies are poised to have a major impact on adoptive T-cell therapy and the investigation of T cell-mediated immunity.

    1984-01-01

    Oceanic dynamics was traditionally investigated by sampling from instruments in situ, yielding quantitative measurements that are intermittent in both space and time; the ocean is undersampled. The need to obtain proper sampling of the averaged quantities treated in analytical and numerical models is at present the most significant limitation on advances in physical oceanography. Within the past decade, many electromagnetic techniques for the study of the Earth and planets were applied to the study of the ocean. Now satellites promise nearly total coverage of the world's oceans using only a few days to a few weeks of observations. Both a review of the early and present techniques applied to satellite oceanography and a description of some future systems to be launched into orbit during the remainder of this century are presented. Both scientific and technologic capabilities are discussed.

  2. Multiple myeloma presenting as gingival hyperplasia.

    Jain, Sanjeev; Kaur, Harjit; Kansal, Gaurav; Gupta, Parul

    2013-05-01

    Multiple myeloma is a malignant neoplasm that is characterized by a monoclonal proliferation of plasma cells. Oral and maxillofacial manifestations as an initial sign or symptom of multiple myeloma are rare. A 58-year-old male patient presented with generalized gingival enlargement for last 6 months. Based on clinical presentation, a diagnosis of gingival hyperplasia was made. After Phase I therapy, excisional biopsy was taken in anterior mandibular region and excised tissue was sent for histopathological examination. The histopathology report revealed a lining of stratified squamous epithelium with foci of ulceration. The subepithelial zone showed infiltration by sheets of mainly binucleate and multinucleate plasma cells, few cells being less differentiated. Rounded cytoplasmic inclusion bodies were identified in many of these cells. After a series of clinical investigations, a case of "multiple myeloma" was diagnosed. Patient presenting with generalized gingival hyperplasia should be worked up for systemic disease like multiple myeloma.

    Background: Cauda equina paragangliomas (CEPs) are rare spinal tumors that are mostly misdiagnosed preoperatively as ependymomas or schwannomas on magnetic resonance imaging (MRI). Clinically, they usually present with the gradual onset of back pain and radiculopathy rather than an acute cauda equina syndrome. Case Description: A 36-year-old female presented with an acute flaccid paraparesis/cauda equina syndrome. Based upon MRI studies, the predominant differential diagnoses included ependymoma or schwannoma. The intraoperative findings revealed an acute intralesional hemorrhage or apoplexy, responsible for the acute clinical deterioration. Histopathology and immunohistochemistry (IHC) revealed that the tumor was a paraganglioma. Conclusion: CEPs commonly present with mild symptoms and signs rather than the acute-onset of a flaccid paraparesis/cauda equina syndrome as seen in this case. Here, the authors review the radiological and histopathological characteristics of CEP and emphasize the role of IHC in differentiating “CEP” from the more common ependymomas. PMID:27127702

    Introduction Gestational trophoblastic neoplasms have highly been malignant potential, which usually occurred in child-bearing age women. Unusual feature of this malignancy would be rare, it was important to take in mind the possibility of GTN in different manifestation. Based on the above mentioned, the aim of this presentation would be the management and outcome of a case series of choriocarcinoma patients with abnormal manifestation. Case Presentation We have presented four patients, first who initially manifestation with signs of septic shock, the second case with severe gastrointestinal hemorrhage, the third case with postpartum infection and the forth case was a postmenopausal bleeding patient. Conclusions In case of metastatic choriocarcinoma with precise history, accurate diagnosis and appropriate treatment have led us to curable results. PMID:27482332

    Introduction. Tympanosclerosis is a commonly encountered entity within ENT clinics and primary care settings. Recognizing ear pathology is essential for correct management. Oftentimes the diagnosis is clear; however in certain cases further workup to rule out other more insidious disease processes is warranted. Case Report. We present a case of tympanosclerosis which presented as an ear mass without classic appearance of tympanosclerosis. Through imaging and biopsy the diagnosis of tympanosclerosis was made. The patient was treated surgically with good outcome. Discussion. Various ear pathologies, with different treatment algorithms, may present as clinically similar to one another. Differential diagnosis for this case included tympanosclerosis, cholesteatoma, or other middle ear masses. We review these entities and discuss their pathophysiology and implications on management.

    2014-01-01

    Graphics are powerful tools to communicate research results and to gain information from data. However, researchers should be careful when deciding which data to plot and the type of graphic to use, as well as other details. The consequence of bad decisions in these features varies from making research results unclear to distortions of these results, through the creation of "chartjunk" with useless information. This paper is not another tutorial about "good graphics" and "bad graphics". Instead, it presents guidelines for graphic presentation of research results and some uncommon, but useful examples to communicate basic and complex data types, especially multivariate model results, which are commonly presented only by tables. By the end, there are no answers here, just ideas meant to inspire others on how to create their own graphics.

    2016-01-01

    Chondroid syringoma (CS) is a rare benign tumor of the sweat gland. It generally presents as a painless, slowly growing, subcutaneous swelling, typically located on the head and neck region. The majority of the cases develop in middle aged and elderly males. We present a case of CS located over the right thumb of a 25-year-old male. The diagnosis was made initially by cytological evaluation and later confirmed by histopathological examination. There was no recurrence on two year follow up after the complete surgical excision of the tumor. PMID:27510678

    A 28-year-old woman presented in her first pregnancy was admitted with severe hyperemesis gravidarium. Increased nuchal translucency with cardiac anomaly and omphalocele at the first trimester was observed at the ultrasound examination. Chorionic villus biopsy confirmed triploidy. The combination of type I and type II triploidy patterns were seen together in the second trimester of the pregnancy. Although the symptoms due to increased human chorionic levels occured, at the pathologic investigation there were no molar changes in the placenta. Here we report a case of uncommon presentation of triploidy. PMID:26557571

    Wuchereria bancrofti is an endemic filarial nematode spread by a mosquito vector. The clinical manifestations vary from asymptomatic microfilaremeia to lymhoedema. We report two cases of microfilaria of Wuchereria bancrofti in bone marrow presenting as peripheral pancytopenia. The patient did not have any classical features of lymphoedema or elephantiasis. The diagnostic demonstration of microfilaria with unusual presentations has been done in cytology specimens from various sites. Microfilaria infection in association with peripheral blood pancytopenia has been rarely reported. An aetiopathological co-relation of these haematological manifestations of microfilaria needs further investigation. PMID:27630856

    Self-mutilation has been defined as deliberate self injury to body tissue without the intent to die. There has been an association between substance abuse and self mutilation. Alcoholic hallucinosis is usually in auditory modality and regarded as harmless. But patients can indulge in self harm behavior when the hallucinosis is commanding type. We are presenting a case in which the patient inflicted multiple stab injury to his own abdomen in response to alcoholic hallucinosis. This has clinical implication to enquire about substance abuse in patients presenting to emergency setting.

    2015-01-01

    Late-onset congenital diaphragmatic hernias that give symptoms beyond the neonatal period are rare and are difficult to diagnose. The diagnosis is usually made in case of complications such as intestinal obstruction, strangulation, and perforation, which further necessitate immediate surgical repair. The case of a 5-year-old child presenting with acute respiratory distress with gastric strangulation and perforation secondary to Bochdalek hernia is reported here. Although presentation in the latter ages is less common, congenital diaphragmatic hernia should be included in the differential diagnosis of respiratory distress in children. Symptoms and diagnostic tools should truly be interpreted. Gastrointestinal complications must urgently be recognized, and early surgical intervention must be performed.

    Rasmussen's encephalitis is a rare syndrome characterized by intractable seizures, often associated with epilepsia partialis continua and symptoms of progressive hemispheric dysfunction. Seizures are usually the hallmark of presentation, but antiepileptic drug treatment fails in most patients and is ineffective against epilepsia partialis continua, which often requires surgical intervention. Co-occurrence of focal cortical dysplasia has only rarely been described and may have implications regarding pathophysiology and management. We describe a rare case of dual pathology of Rasmussen's encephalitis presenting as a focal cortical dysplasia (FCD) and discuss the literature on this topic. PMID:25667877

    Oropharyngeal lymphatic malformations usually present with a mass either at birth or in the first 2 years of life. Rarely, lymphatic malformations present with extremely progressive respiratory problems shortly after birth, and usually occur in cases which have remained undetected in the absence of antenatal ultrasound. We report the case of a newborn that required tracheostomy and gastrostomy due to a rapidly expansive lymphatic malformation. MRI showed multilocular microcystic lymphatic malformation. Intralesional bleomycin injections proved to be successful in this patient. A short review of epidemiology, clinical manifestation and treatment is given. PMID:23907961

On imaging she was found to be having a lobulated mass with a radiological differential diagnosis of malignancy, lymphoma or a rare inflammatory lesion. After an inconclusive CT guided biopsy the patient underwent thoracoscopy on which an unresectable mass was found. The biopsy from the mass revealed pulmonary hyalinizing granuloma (PHG). To best of our knowledge this is the first case of PHG presenting as dysphagia reported in the English Literature. Literature on this rare entity is reviewed. PMID:12974440

    The majority of the newly developed enhanced gravity concentrators (EGCs) have tremendous potentials for various applications. Therefore, the performance evaluation of these concentrators treating various minerals, coals, heavy metal recovery from tailing dams, etc., have become an active research topic. Several attempts have also been made to develop appropriate mathematical models of individual concentrators. Despite all these efforts, these concentrators have yet to find the widespread applications they deserve. The present status of modeling these EGCs with a brief description of the operating principles and the present applications are, therefore, reviewed in this article. Research needs in this direction are also highlighted.

    Mycosis fungoides is a potentially fatal skin condition whose variable clinical appearance may mimic a variety of benign, inflammatory dermatoses, making it a diagnostic challenge. Three patients with mycosis fungoides, treated with multiple approved topical and systemic therapies, presented with acquired verrucous lesions on the extremities. The verrucous presentation of mycosis fungoides is one of the many atypical forms of the disease, with a paucity of documented cases in the medical literature. Although rare, verrucous and hyperkeratotic lesions in mycosis fungoides may increase the risk of considerable diagnostic delay if clinicians do not maintain a high degree of suspicion in cases of acquired verrucous lesions in the appropriate clinical setting.

Patients with AES typically present with the development of recurrent, spontaneous, painful ecchymosis, frequently preceded by a prodrome of pain or itching of the skin. The patients are sensitive to their own red blood cells injected intradermally, and underlying coagulopathies are thought to be absent. We introduce a 70-year-old woman presenting with recurrent episodes of painful bruising on the trunk and extremities. PMID:23956968

    The differential diagnoses of neck mass may include a wide spectrum of lesions ranging from cysts, inflammatory processes, benign and malignant tumors arising from skin, soft tissue, lymph nodes, endocrine glands, salivary glands to metastatic tumors. In adults, malignant non-thyroid neck masses are often metastatic squamous cell carcinoma. Gynecomastia, presenting as a mass or enlargement in its typical subareolar location is usually a straightforward diagnosis. Enlargement due to gynecomastia in locations other than subareola can pose diagnostic challenge. We describe a unique case of gynecomastia presenting as a neck mass in a patient who was diagnosed and treated for squamous cell carcinoma of the floor of the mouth.

  13. Antigen Presentation by MHC-Dressed Cells

    PubMed Central

    Nakayama, Masafumi

    2015-01-01

    Professional antigen-presenting cells (APCs) such as conventional dendritic cells (DCs) process protein antigens to MHC-bound peptides and then present the peptide–MHC complexes to T cells. In addition to this canonical antigen presentation pathway, recent studies have revealed that DCs and non-APCs can acquire MHC class I (MHCI) and/or MHC class II (MHCII) from neighboring cells through a process of cell–cell contact-dependent membrane transfer called trogocytosis. These MHC-dressed cells subsequently activate or regulate T cells via the preformed antigen peptide–MHC complexes without requiring any further processing. In addition to trogocytosis, intercellular transfer of MHCI and MHCII can be mediated by secretion of membrane vesicles such as exosomes from APCs, generating MHC-dressed cells. This review focuses on the physiological role of antigen presentation by MHCI- or MHCII-dressed cells, and also discusses differences and similarities between trogocytosis and exosome-mediated transfer of MHC.

  8. The presentation and management of fibromatosis colli.

    PubMed

    Lowry, Kristen C; Estroff, Judy A; Rahbar, Reza

    2010-09-01

    We conducted a systematic chart review to identify all infants with fibromatosis colli who had been seen at Children's Hospital in Boston from January 1999 through December 2004. We found 7 such cases, which involved 4 boys and 3 girls, aged 1 to 3.5 weeks at presentation. We compiled information on each patient's birth history, presenting signs and symptoms, significant medical history, imaging findings, management, follow-up, and outcome. Six of the 7 patients presented with a neck mass, and the remaining patient presented with neck "fullness." Five patients developed torticollis at some point. All patients were treated conservatively with physiotherapy. Five patients experienced a complete resolution of signs and symptoms, and the other 2 experienced improvement. Based on our findings, we recommend that early management of fibromatosis colli include observation and physiotherapy to prevent or reverse torticollis and the craniofacial asymmetry that can result. Similarly attractive is the opportunity that physiotherapy provides for parents to involve themselves in the care of their newborn. It is important, therefore, to quickly identify fibromatosis colli as such in order to avoid unnecessary expenditures of resources and to promptly begin conservative treatment.

    2011-01-01

    This paper surveys the instrument pointing capabilities of past, present and future space telescopes and interferometers. As an important aspect of this survey, we present a taxonomy for "apples-to-apples" comparisons of pointing performances. First, pointing errors are defined relative to either an inertial frame or a celestial target. Pointing error can then be further sub-divided into DC, that is, steady state, and AC components. We refer to the magnitude of the DC error relative to the inertial frame as absolute pointing accuracy, and we refer to the magnitude of the DC error relative to a celestial target as relative pointing accuracy. The magnitude of the AC error is referred to as pointing stability. While an AC/DC partition is not new, we leverage previous work by some of the authors to quantitatively clarify and compare varying definitions of jitter and time window averages. With this taxonomy and for sixteen past, present, and future missions, pointing accuracies and stabilities, both required and achieved, are presented. In addition, we describe the attitude control technologies used to and, for future missions, planned to achieve these pointing performances.

    2016-01-01

    Background Neuroferritinopathy (NF) is a rare autosomal dominant disease caused by mutations in the ferritin light chain 1 (FTL1) gene leading to abnormal excessive iron accumulation in the brain, predominantly in the basal ganglia. Methods A literature search was performed on Pubmed, for English-language articles, utilizing the terms iron metabolism, neurodegeneration with brain iron accumulation, and NF. The relevant articles were reviewed with a focus on the pathophysiology, clinical presentation, differential diagnoses, and management of NF. Results There have been nine reported mutations worldwide in the FTL1 gene in 90 patients, the most common mutation being 460InsA. Chorea and dystonia are the most common presenting symptoms in NF. There are specific features, which appear to depend upon the genetic mutation. We discuss the occurrence of specific mutations in various regions along with their associated presenting phenomenology. We have compared and contrasted the commonly occurring syndromes in the differential diagnosis of NF to guide the clinician. Discussion NF must be considered in patients presenting clinically as a progressive movement disorder with variable phenotype and imaging evidence of iron deposition within the brain, decreased serum ferritin, and negative genetic testing for other more common movement disorders such as Huntington’s disease. In the absence of a disease-specific treatment, symptomatic drug therapy for specific movement disorders may be used, although with variable success. PMID:27022507

    2011-02-15

    A 45-year-old male presented with a 6 month history of an enlarging smooth, erythematous plaque over the central part of his face. Mild erythema of both eyes was present. Sarcoidosis, Hansen disease, lupus vulgaris, cutaneous leishmaniasis, pseudolymphoma, foreign body granuloma, granuloma faciale, discoid lupus erythematosus, and granulomatous rosacea were considered in the differential diagnosis. CBC, urinalysis, renal function tests, liver function tests, serum electrolytes, and blood sugar were all normal. Chest X-ray and ECG revealed no abnormality. Serology for syphilis and HIV, and mantoux test were negative. Slit-skin smear, tissue smear and culture for AFB and fungi were negative. Skin biopsy revealed multiple non-caseating epitheloid granulomas around the pilosebaceous unit suggestive of granulomatous rosacea. Granulomatous rosacea, a rare entity comprising only about 10 percent of cases of rosacea can mimic many granulomatous conditions both clinically and histologically making the diagnosis an enigma. It usually presents as yellowish brown-red discrete papules on the face; non-caseating epithelioid granulomas are seen on histology examination. We herein report the case because it presented in atypical fashion, as a solitary indurated plaque on the nose, likely representing Morbihan's disease or solid persistent facial edema of rosacea (rosacea lymphedema).

    2014-01-01

    Lysinuric protein intolerance (LPI) is a rare autosomal recessive inborn error of metabolism caused by mutations in SLC7A7, which encodes a component of the dibasic amino acid transporter found in intestinal and renal tubular cells. Patients typically present with vomiting, diarrhea, irritability, failure to thrive, and symptomatic hyperammonemia after protein-rich meals. Long-term complications may include pulmonary alveolar proteinosis, renal disease, and osteoporosis. We present a 5-year-old male who was followed in our skeletal dysplasia clinic for 3 years for multiple fractures, idiopathic osteoporosis, and short stature in the absence of typical features of LPI. Whole exome sequencing performed to determine the etiology of the osteoporosis and speech delay identified a nonsense mutation in SLC7A7. Chromosome microarray analysis identified a deletion involving the second allele of the same gene, and biochemical analysis supported the diagnosis of LPI. Our patient's atypical presentation underscores the importance of maintaining a high index of suspicion for LPI in patients with unexplained fractures and idiopathic osteoporosis, even in the absence of clinical symptoms of hyperammonemia after protein rich meals or other systemic features of classical LPI. This case further demonstrates the utility of whole exome sequencing in diagnosis of unusual presentations of rare disorders for which early intervention may modify the clinical course.

  7. Recognition and memory for briefly presented scenes.

    PubMed

    Potter, Mary C

    2012-01-01

    Three times per second, our eyes make a new fixation that generates a new bottom-up analysis in the visual system. How much is extracted from each glimpse? For how long and in what form is that information remembered? To answer these questions, investigators have mimicked the effect of continual shifts of fixation by using rapid serial visual presentation of sequences of unrelated pictures. Experiments in which viewers detect specified target pictures show that detection on the basis of meaning is possible at presentation durations as brief as 13 ms, suggesting that understanding may be based on feedforward processing, without feedback. In contrast, memory for what was just seen is poor unless the viewer has about 500 ms to think about the scene: the scene does not need to remain in view. Initial memory loss after brief presentations occurs over several seconds, suggesting that at least some of the information from the previous few fixations persists long enough to support a coherent representation of the current environment. In contrast to marked memory loss shortly after brief presentations, memory for pictures viewed for 1 s or more is excellent. Although some specific visual information persists, the form and content of the perceptual and memory representations of pictures over time indicate that conceptual information is extracted early and determines most of what remains in longer-term memory.

  8. SSP: Sketching Slide Presentations, a Syntactic Approach

    NASA Astrophysics Data System (ADS)

    Mas, Joan; Sanchez, Gemma; Lladós, Josep

    The design of a slide presentation is a creative process. In this process first, humans visualize in their minds what they want to explain. Then, they have to be able to represent this knowledge in an understandable way. There exists a lot of commercial software that allows to create our own slide presentations but the creativity of the user is rather limited. In this article we present an application that allows the user to create and visualize a slide presentation from a sketch. A slide may be seen as a graphical document or a diagram where its elements are placed in a particular spatial arrangement. To describe and recognize slides a syntactic approach is proposed. This approach is based on an Adjacency Grammar and a parsing methodology to cope with this kind of grammars. The experimental evaluation shows the performance of our methodology from a qualitative and a quantitative point of view. Six different slides containing different number of symbols, from 4 to 7, have been given to the users and they have drawn them without restrictions in the order of the elements. The quantitative results give an idea on how suitable is our methodology to describe and recognize the different elements in a slide.

    2015-01-01

    Introduction Emergency departments see an increase in cases during cyclones. The aim of this study is to describe patient presentations to the Emergency Department (ED) of a tertiary level hospital (Townsville) following a tropical cyclone (Yasi). Specific areas of focus include changes in: patient demographics (age and gender), triage categories, and classification of diseases. Methods Data were extracted from the Townsville Hospitals ED information system (EDIS) for three periods in 2009, 2010 and 2011 to coincide with formation of Cyclone Yasi (31 January 2011) to six days after Yasi crossed the coast line (8 February 2012). The analysis explored the changes in ICD10-AM 4-character classification and presented at the Chapter level. Results There was a marked increase in the number of patients attending the ED during Yasi, particularly those aged over 65 years with a maximum daily attendance of 372 patients on 4 Feb 2011. The most marked increases were in: Triage categories - 4 and 5; and ICD categories - diseases of the skin and subcutaneous tissue (L00-L99), and factors influencing health care status (Z00-Z99). The most common diagnostic presentation across all years was injury (S00-T98). Discussion There was an increase in presentations to the ED of TTH, which peaked in the first 24 – 48 hours following the cyclone and returned to normal over a five-day period. The changes in presentations were mostly an amplification of normal attendance patterns with some altered areas of activity. Injury patterns are similar to overseas experience. PMID:26111010

    Gallamini, Andrea; Hutchings, Martin; Ramadan, Safaa

    2016-07-01

    In the present chapter the authors present a brief overview of the diagnostic methods proposed over time for Hodgkin lymphoma (HL) spread detection, moving from surgical procedures, through standard radiological and functional imaging techniques to the present state of the art for HL staging. The main body of the review will be dedicated to the recently published guidelines for lymphoma staging (including HL) agreed by the experts during the 12th International Congress for Malignant Lymphoma in Lugano. The recommendations of the panel on how to integrate flurodeoxyglucose positron emission tomography (FDG-PET) scan in the armamentarium of staging procedures will be presented and commented, with a special emphasis on the utility of special procedures, such as bone marrow trephine biopsy, which is deemed no longer needed in the PET era. While the HL diagnosis is straightforward in most cases, sometimes HL is a subtle disease, difficult to diagnose for the paucity of symptoms, the absence of physical findings, or for concomitant immunologic disorders: a compete overview of the common and rare patterns of HL clinical presentation will be also offered. The future perspective of PET scan use will be based on a operator-independent, quantitative readings of the scan thanks to a plethora of sophisticated dedicated software, which are now available, able to quantify every voxel captured by the tumor to display the metabolically active tumor volume. Moreover, new tracers are now available able to track the new pathways of cellular metabolism beside glycolysis such as amino acids or purine-analogues or specific oncoproteins; the preliminary, promising results will be reported. Preliminary results from other imaging techniques, such as diffusion-weighted magnetic resonance (DW-MRI) will be also reported. PMID:27496305

    Presentation assignments for second language speakers can take several forms, such as a traditional class presentation or a poster presentation. Poster presentations, which are given repeatedly to small groups, seem to have several advantages, including increased speaking opportunities, more interaction between the speaker and the audience, and…

  13. [Atypical presentation of an induced hyperthyroidism].

    PubMed

    Duque, María Del Pilar Velásquez; Miranda, Jaime Bernal

    2013-03-01

    We present the case of a person with baseline Bipolar Affective Disorder, who starts receiving medical treatment for subclinical Hypothyroidism, during this time the patient develops Hyperthyroidism. During the course of the latter, the patient started to exhibit depressed mood symptoms and worsening of her baseline disorder. Typically there are depressive symptoms in hypothyroidism and manic symptoms in hyperthyroidism, there have been a few cases of depressive symptoms (depressed mood, asthenia and apathy) reported in patients with hyperthyroidism. Up till now it's a fact that Hyperthyroidism constitutes itself as a risk factor for developing or precipitating depressive states, thus increasing hospital readmissions, and another important fact is that of manifesting or worsening affective symptoms due to the influence of thyroid hormones. We also present the well-known relationship between thyroid malfunction and affective disorders. PMID:26572720

  14. Multiple Fibromas of Tendon Sheath: Unusual Presentation

    2011-01-01

    Fibroma of the tendon sheath is an uncommon soft tissue tumor presenting as a solitary, slow-growing, firm, painless, small nodule, which shows strong attachment to the tendon or tendon sheath. It is usually localized on fingers and hand tendons in adults between the age of 20 and 40 years old. This case concerns a 61-year-old man presenting with a 5-year history of multiple cutaneous nodules on both palms and soles. Skin biopsy confirmed fibroma of the tendon sheath. Blood tests showed a high titer of rheumatoid factor and positivity to anti-nuclear antibody. No case of fibroma of the tendon sheath occurring multifocally on both palms and soles has been previously reported. Herein, we report on a very rare case of multiple fibromas of the tendon sheath arising from palms and soles, which supports the pathogenetic hypothesis that this tumor may be a reactive process rather than a true neoplasm.

    Munchausen by proxy is a disorder in which a child is victimized through a form of child abuse called pediatric condition falsification (PCF). PCF has been documented for psychological and psychiatric conditions including one such form presented here in which educational disabilities are the focus of falsification. Parents meet their own self-serving needs through "impostering" as good mothers. This maternal mental disorder is called factitious disorder by proxy. This article presents a series of cases in which children have PCF that primarily consists of educational disabilities. Characteristics of the children, their mothers, and their families are outlined and outcomes for the 9 children in the sample are discussed. Guidelines for identification of children with PCF in educational settings are provided, and special guidance is offered in differential diagnosis.

  16. Incentivizing Distributed Solar: Best Practices (Presentation)

    Bird, L.; Reger, A.

    2013-06-01

    The presentation discussed findings of a recent NREL technical report on best practices for designing and implementing incentives for small and mid-sized residential and commercial distributed solar energy projects. Topics covered included: factors to consider in setting and modifying incentive levels over time, differentiating incentives to encourage various market segments, and administrative issues such as providing equitable access to incentives and customer protection. In addition, the presentation explored how incentive programs can be designed to respond to changing market conditions while attempting to provide a longer-term and stable environment for the solar industry. The findings of the report were based on interviews with program administrators, regulators, and industry representatives as well as data from numerous incentive programs nationally, particularly the largest and longest-running programs.

  17. Rheumatoid nodule presenting as Morton's neuroma.

    PubMed

    Chaganti, S; Joshy, S; Hariharan, K; Rashid, M

    2013-09-01

    Among 101 feet that presented with symptoms and signs similar to Morton's neuroma, intermetatarsal rheumatoid nodules were found in five feet (three patients). Two patients had bilateral involvement. Histology of the excised tissue showed the presence of a rheumatoid nodule and Morton's neuroma in four feet and a rheumatoid nodule with unremarkable nerve bundles in one. A rheumatoid nodule can coexist with Morton's neuroma, as seen in our patients, and the presentation is often similar to that of a Morton's neuroma. Our patients were rendered asymptomatic with surgical treatment and went on to have appropriate management of rheumatoid arthritis. Rheumatoid nodule should be considered in the differential diagnosis of Morton's neuroma in not only rheumatoid arthritis patients but also asymptomatic patients who have never been tested for rheumatoid antibodies.

  18. Intraventricular neurocysticercosis: Presentation, diagnosis and management.

    PubMed

    Jensen, Tomas Ostergaard; Post, Jeffrey John

    2016-08-01

    Neurocysticercosis is thought to be the most common helminthic infection of the central nervous system and its epidemiology is changing due to increasing travel and migration. Evidence to guide management of the intraventricular form is limited. We aimed to review the clinical presentation, diagnosis and treatment of intraventricular neurocysticercosis with reference to two recent cases seen at our institution. The intraventricular variant of neurocysticercosis is less common than parenchymal disease and usually presents with acutely raised intracranial pressure and untreated it progresses rapidly with high mortality. The diagnosis is based on imaging and serological tests but more invasive testing including histopathological examination of surgically acquired tissue specimens is sometimes required. Treatment is mainly surgical, using a neuroendoscopic approach if possible. Patients should also receive antihelmintic treatment with concomitant corticosteroids to reduce the incidence of shunt failure if a ventricular shunt is inserted and to treat viable lesions elsewhere.

  19. Case report: Diaper dermatitis presenting as pustules.

    PubMed

    2014-09-01

    Diaper dermatitis is the most common dermatologic disorder of infancy. Its cause can often be determined clinically based on the clinical presentation. Primary diaper dermatitis is associated with irritants and spares the deep skin folds. Secondary diaper dermatitis is most often caused by Candida yeast overgrowth and typically presents as a well-defined area of beefy red erythema covering the diaper area and including the deep folds of skin with hallmark satellite pustules. Other causes include seborrheic dermatitis, psoriasis, acrodermatitis enteropathica, allergic contact dermatitis, Langerhans cell histiocytosis, and, in the setting of a primarily pustular eruption, bacterial folliculitis. A simple potassium hydroxide preparation (KOH) can confirm the diagnosis of candida diaper dermatitis and guide proper treatment.

  1. Burkitt lymphoma with unusual presentation: Acute pancreatitis.

    PubMed

    Koca, Tugba; Aslan, Nagehan; Dereci, Selim; Akcam, Mustafa

    2015-08-01

    Pancreatitis due to malignant infiltration is an uncommon condition in childhood. Pancreatic lymphomas constitute <2% of all non-Hodgkin lymphomas. Only six reported cases with various clinical presentation have been documented in the literature. Described herein is the case of a nine-year-old boy with abdominal pain, jaundice, emesis, weight loss, diarrhea, who developed hyperlipidemia and cholestasis. Pancreatitis was suspected due to high amylase and lipase. Computed tomography and magnetic resonance cholangiopancreatography showed diffuse enlargement of the pancreas. This sausage pancreas imaging was suggestive of autoimmune pancreatitis, but the patient was diagnosed with Burkitt lymphoma on bone marrow aspiration, and rapidly improved with chemotherapy. Burkitt lymphoma should be kept in mind when patients present with pancreatitis, especially with diffuse enlarged pancreas. PMID:26031558

    2016-01-01

    Epithelioid hemangioendothelioma is a rare vascular neoplasm of borderline or low-grade malignant potential uncommonly seen in head and neck region and has not been reported in the hypopharynx. We present here a case of epithelioid hemangioendothelioma arising from the hypopharynx in a young female patient who presented with progressive dysphagia for 1-year and difficulty in breathing for 1-month. This is first reported case in published English literature to the best of our knowledge. Recognition of this borderline entity is necessary because of its potential for malignant transformation and recurrence. A wide excision and regular clinical follow-up would be an appropriate treatment protocol. The role of other therapeutic modalities such as chemotherapy and/or radiotherapy is not yet well established. PMID:27433056

    The present capability and future potential of accelerator-based monoenergetic and white neutron sources are outlined in the context of fundamental and applied neutron-nuclear research. The neutron energy range extends from thermal to 500 MeV, and the time domain from steady-state to pico-second pulsed sources. Accelerator technology is summarized, including the production of intense light-ion, heavy-ion and electron beams. Target capabilities are discussed with attention to neutron-producing efficiency and power-handling capabilities. The status of underlying neutron-producing reactions is summarized. The present and future use of neutron sources in: fundamental neutron-nuclear research, nuclear data acquisition, materials damage studies, engineering tests, and biomedical applications are discussed. Emphasis is given to current status, near-term advances well within current technology, and to long-range projections. 90 refs., 4 figs.

  4. Morgellons Disease Presenting As an Eyelid Lesion.

    PubMed

    Sandhu, Rasanamar K; Steele, Eric A

    2016-01-01

    Morgellons disease is characterized by complaints of uncomfortable skin sensations and fibers emanating from nonhealing skin lesions. Morgellons disease is well-known in the dermatology and psychiatry literature, where it is typically considered a subtype of delusional parasitosis, but it has not yet been described in the ophthalmology literature. A patient with self-reported Morgellons disease is presented, who was referred for evaluation of left lower eyelid ectropion. She reported that her skin was infested with fibers that were "trying to get down into the eyelid." On examination, she had ectropion of the left lower eyelid, broken cilia, and an ulcerated left upper eyelid lesion concerning for carcinoma. Biopsy of the lesion was consistent with excoriation. Treatment of her ectropion was deferred out of concern for wound dehiscence, given the patient's aggressive excoriation behavior. This case is presented to make the ophthalmologist aware of this disorder and to highlight the appropriate clinical management. PMID:25192328

    2000-06-01

    We describe a 37-year-old woman who presented with palmoplantar pigmentation, thickening and pitting of 4 years duration. Bluish pigmented patches were seen over the sclera of her eyes. Her lumbar spine showed typical calcification of the intervertebral discs. Addition of Benedict's reagent to a urine sample of the patient gave rise to greenish brown precipitate and brownish black supernatant. Alkalinization of urine turned it black. A biopsy of the palmar lesion demonstrated irregular breaking up, swelling and homogenization of collagen bundles in the reticular dermis. Yellow-brown (ochre coloured) pigment was seen lying within the collagen bundles and also freely in the deeper dermis confirming our clinical diagnosis of alkaptonuric ochronosis. To the best of our knowledge this is probably the second report of alkaptonuria presenting with palmoplantar pigmentation. PMID:10971492

    A 44-year-old man presented with severe pain, redness, watering and photophobia for 10 days in the right eye without any history of trauma. Diagnosis of herpes simplex disciform keratitis was made and he was prescribed topical steroids. The patient showed clinical worsening and presented with ring infiltrate, diffuse stromal oedema and radial keratoneuritis, a finding pathognomic of acanthamoeba keratitis. With two inconclusive corneal scrapings and the patient showing clinical worsening, an urgent therapeutic penetrating keratoplasty was carried out. Histopathological and microbiological examination of the excised corneal button revealed the presence of fungus. At 5 weeks follow-up, the patient has best-corrected visual acuity 20/40 with no recurrence of infection. PMID:24717856

Phase I of the project reviews simulated/prototypical data sets from 10 companies. Phase II of the project is a 3 year purchase/distribution of select data from 5 companies. The status of several SDP projects is reviewed in this viewgraph presentation, as is the SDP process of tasking, verification, validation, and data archiving. The presentation also lists SDP results for turnaround time, metrics, customers, data use, science research, applications research, and user feedback.

  8. An unusual presentation of carcinomatous meningitis

    PubMed Central

    Foo, Chuan T.; Burrell, Louise M.; Johnson, Douglas F.

    2016-01-01

    A 67-year old previously well male presented with a 1 week history of confusion on a background of 3 weeks of headache. Past history included two superficial melanomas excised 5 years ago. Treatment for meningoencephalitis was commenced based on lumbar puncture (LP) and non-contrast brain magnetic resonance imaging (MRI) results. Lack of a clinical response to antibiotics resulted in a second LP and contrast brain MRI which demonstrated hydrocephalus and leptomeningeal disease. Ongoing deterioration led to a whole-body computed tomographic and spinal MRI that showed widespread metastatic disease and extensive leptomeningeal involvement of the spinal cord. The diagnosis of metastatic melanoma with carcinomatous meningitis was made based on cytological analysis of cerebrospinal fluid. He died 2 weeks later in a palliative care facility. This case illustrates that the diagnosis of carcinomatous meningitis can be difficult to make as the heterogeneous nature of its presentation often delays the diagnosis. PMID:27574561

    2016-01-01

    A 52-year-old female with a history of poorly controlled resistant hypertension was admitted to our hospital with severe hypertension. She had a history of fatigue and intermittent episodes of palpitations. Laboratory evaluation was significant for elevated 24-h urinary catecholamine levels (3,5 times the upper normal levels). This case was presenting with a clinical and biochemical picture indistinguishable from that of pheochromocytoma. However, neither computed tomography nor meta-iodo-benzyl-guanidine scintigraphy detected any catecholamine-producing tumor in or outside the adrenal glands. Our patient was screened with full polysomnography because of heavy snoring, daytime somnolence and obesity. It revealed severe obstructive sleep apnea syndrome. After three months of continuous positive airway pressure therapy, the patient experienced resolution of his presenting symptoms, improved blood pressure control and normalization of his urinary catecholamine levels. This case highlights sleep disordered breathing as a potentially reversible cause of pseudo-pheochromocytoma. PMID:27217898

    2014-01-01

    Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) has significant variability in its presentation. In this study, we present 2 novel cases of prostatitis in which “buzz” is described as the primary pain symptom. These cases describe patients with the primary complaint of “cell phone–like buzzing” within the perineum, with accompanying urinary symptoms consistent with prostatitis. CP/CPPS is a multifactorial disease within which psychological, inflammatory, neurologic, and neuromuscular etiologies are at play. As in other disease descriptions, a buzzing sensation represents the interaction of multiple pathways that have significant overlay with CP/CPPS. As such, we believe buzzing might represent a new symptom of CP/CPPS. PMID:26955537

    2015-04-09

    Pituitary apoplexy, a syndrome caused by haemorrhage into the pituitary gland, typically manifests as sudden severe headache, visual symptoms and hypopituitarism, including adrenal insufficiency. We report a case of a 65-year-old man with adrenal insufficiency due to pituitary apoplexy presenting with anorexia following temporal headache and diagnosed through evaluation for hyponatraemia. MRI focusing on the pituitary gland helped to confirm the diagnosis. Our experience serves as a useful reminder of this atypical presentation of pituitary apoplexy, also known as 'subclinical pituitary apoplexy,' and underscores the importance of careful evaluation for hyponatraemia using serial urine osmolality, which is useful to distinguish hypovolaemic hyponatraemia from euvolaemic hyponatraemia. Clinicians should consider pituitary apoplexy as a differential diagnosis in cases of anorexia, loss of energy or hyponatraemia, following headache even when the patient is lacking classical symptoms such as severe headache or visual symptoms.

    2012-12-01

    We report a case of a 5-year-old boy with acute disseminated encephalomyelitis as the initial presentation of neuroborreliosis. Parents report an upper-airway infection a few days before the development of acute encephalopathy, mild facial palsy, and seizures. The patient needed mechanical ventilation for 10 days, and after extubation, he presented hypotonia, ataxia, dysarthria, as well as weak gag and cough reflexes. Brain magnetic resonance imaging showed hyperintense lesions on T2- and fluid-attenuated inversion recovery sequences on the right subcortical occipital and parietal region, left posterior arm of the internal capsule, and in the medulla oblongata. Borrelia burgdorferi was identified in the plasma and cerebrospinal fluid by polymerase chain reaction and in the plasma by Western blotting. He was treated with ceftriaxone, methylprednisolone, and human immunoglobulin. Recovery was partial. PMID:23222106

  14. Cosmology: from Pomeranchuk to the Present Day

    NASA Astrophysics Data System (ADS)

    Dolgov, A. D.

    A short and, due to lack of time (half a century of the science progress in half an hour), rather superficial review on the development of cosmology for scientists working on particle and nuclear physics is presented. The introductory historical part is mostly dedicated to the fundamental works done in Russia (USSR), but not always well known outside the country. Next, the key papers on theory and on astronomical observations, which determined the progress in cosmology during the last half-century or posed crucial problem, are discussed. Among them there are inflation, baryogenesis, dark matter, dark energy, the vacuum energy problem, modification of gravity at large scales, and angular fluctuations of the cosmic microwave background radiation. The presentation is probably biased towards cosmology as it is seen from Russia (or from ITEP) and reflects personal prejudice of the author.

    Neuroretinitis is the inflammation of retina and optic nerve. It is associated with optic disc edema accompanied by peripapillary or macular hard exudates. A 17 yr old female presented with headache and nausea of five days duration. She had periorbital edema and mild splenomegaly. Neurological assessment was non-contributory. She was found to have pancytopenia, albuminuria and a high ESR. Thereafter she developed blurring of vision of both eyes. Opthalmological examination showed it to be due to bilateral neuroretinitis. ANA and anti-ds DNA were strongly positive. Renal biopsy with immunofluorescence study revealed diffuse global proliferative lupus nephritis with active lesions [class IV-G (A)]. She was diagnosed as a case of SLE presenting with neuroretinitis. PMID:27608700

    2014-01-01

    Langerhans cell histiocytosis (LCH) is a relatively rare and unique disease. An incidence of 7.9% in the jaws is reported. We report a case of 9-year-old male child referred to us from dental outpatient department, who presented with a firm swelling in right lower jaw along with bilateral submandibular lymphadenopathy for 1-month. Fine-needle aspiration was done from lytic lesion in the body of mandible and multiple smears were prepared. On the basis of the clinical and cytomorphological findings, a diagnosis of LCH was suggested. The diagnosis was confirmed on histology. Thus, a high possibility of LCH should be considered in children presenting with lytic lesions in head and neck region. PMID:25745295

    Gynecomastia is a benign enlargement of the male breast caused by the proliferation of glandular breast tissue. Determining the various causes of gynecomastia such as physiological causes, drugs, systemic diseases, and endocrine disorders is important. Androgen insensitivity syndrome (AIS) is a rare endocrine disorder presenting with gynecomastia and is a disorder of male sexual differentiation caused by mutations within the androgen receptor gene. All individuals with AIS have the 46 XY karyotype, although AIS phenotypes can be classified as mild, partial or complete and can differ among both males and females including ambiguous genitalia or infertility in males. We experienced a case of partial AIS presenting with gynecomastia and identified the androgen receptor gene mutation. PMID:25433660

    Ohman, Y.

    1983-05-01

    Published literature is examined for evidence of the presence of plasma satellites among the solar chromospheric lines. Indications are found that first-order plasma satellites sometimes appear as a pair of faint chromospheric emission lines in places where forbidden lines, mainly of metals, should be located. Evidence is seen that second-order plasma satellites are present among lines for which emission wings show asymmetry with respect to the distances from the line center and with respect to intensity. Indications are found that fourth-order plasma satellites are present as unidentified diffuse lines situated near parent lines of food strength either in emission or in absorption. All three types of satellites show electron densities on the order of a trillion/cu cm. Indications that plasma satellites may sometimes appear as faint absorption lines in the solar spectrum are discussed.

    Czech dysplasia, metatarsal type is an autosomal dominant skeletal disorder that is characterized by early-onset, progressive arthritis, brachydactyly of the 3rd and 4th toes, and characteristic radiographic findings in patients of normal stature. Patients with Czech dysplasia typically present in late childhood or later. In the present report, whole exome sequencing identified a mutation in COL2A1 (c.823C>T, p.R275C) known to be associated with Czech dysplasia in a 3.5 year old female who had a family history of early-onset arthritis and who was asymptomatic except for prominent knees. The use of whole exome sequencing facilitated diagnosis of this rare disease (less than 15 families in the literature) in the presymptomatic period and thus enabled us to provide early anticipatory guidance and genetic counseling for the family.

    A 2-year-old girl presented to hospital, with reduced consciousness and fever. She had a 4-week history of fever treated with two courses of amoxicillin for tonsillitis diagnosed in primary care. Neuroimaging revealed multiple cerebral abscesses and subdural empyema. Pus aspirated from the intracranial collections grew Fusobacterium necrophorum and meropenem was started. Following neurosurgery, the patient continued to be agitated with fluctuating fever. She underwent close monitoring with regular neuroimaging. To control the progression of intracranial infection, she underwent three separate neurosurgical procedures following which she made a good recovery. This case demonstrates how an organism rarely associated with childhood illnesses presented atypically and progressed into a complex potentially fatal intracranial infection requiring a high degree of neurosurgical intervention. Awareness of this organism is important. The combination of source control together with appropriate antibiotic use was crucial in controlling the infection.

    Pili torti also known as ‘twisted hairs’ (Latin: pili=hair; torti=twisted) is a rare, congenital or acquired clinical presentation, in which the hair shaft is flattened at irregular intervals and twisted 180º along its axis. It is clinically characterized by fragile, brittle, coarse and lusterless hairs, due to uneven light reflection on the twisted hair surface. Pili torti may be associated with neurological abnormalities and ectodermal dysplasias. There is no specifi c treatment for this condition, but it may improve spontaneously after puberty. We report a case of pili torti in a child who presented fragile, brittle, diffi cult to comb hair. The patient had no comorbidities. PMID:26312667

    2015-01-01

    Hepatocellular carcinoma (HCC) is a primary malignancy of the liver with up to half of cases suffering from extrahepatic metastasis in the later stages of the disease. Commonly reported and encountered metastatic sites include the lymph nodes, lung, bone, and adrenal glands. This is an effort to throw a spotlight on a rare case of metastatic HCC which presented to us as two distinct lesions in the nose. It focuses on the presentation and the steps that were taken to reach this rare and unusual diagnosis. It sparks interest from a clinical and histopathology perspective. Our cynosure is the findings of the case coupled with a probe on the possible routes of spread of HCC to sinonasal region. PMID:26618018

    2016-01-01

    Context: Elderly patients with visual loss often have age-related macular degeneration, diabetic retinopathy, glaucoma, and cataract as common causes of visual loss. Other less common etiologies should be considered, especially in those presenting with systemic associations. Case Report: The patient discussed in our review is an 80-year-old female, with a history of diabetic retinopathy and macular degeneration who presented with a sudden deterioration of vision. While this was initially attributed to diabetic retinopathy, she was eventually noted to have a salmon patch lesion in her conjunctiva, diagnosed on biopsy to be a diffuse large B-cell lymphoma. Conclusion: Because of the significant rate of disseminated disease among patients with lymphomas in the orbit that carries a worse prognosis, early diagnosis is essential to promote better overall survival of these patients. We describe here a patient diagnosed with conjunctival lymphoma associated with pronounced visual loss and review the literature on this subject. PMID:27011948

  10. Radar and sensor netting - Present and future

    NASA Astrophysics Data System (ADS)

    Farina, A.; Studer, F. A.

    1986-01-01

    It is pointed out that a natural evolution of radar systems leads to the netting of radars dispersed on a certain portion of the surveillance space. The motivation for this evolution was provided by the possibility of fusing a great amount of data taken by radars operating independently. Multiradar tracking (MRT) represents a well-known system employed in civilian and military applications. The multistatic radar system is another well known netting concept. The present paper has the objective to provide some information regarding the potential of the netted system concepts. The netting of sensors other than radars is also promising, taking into account lasers, TV, radiometer, and acoustic devices. Attention is given to details concerning the multiradar system concept (the present), the multistatic system concept, wideband netting (the future), the multisensor system concept (the future), and artificial intelligence.

    2005-04-01

    We report the case of an acute type A aortic dissection occurring in a 35-year-old parturient. The initial diagnosis was missed; a subsequent emergency Caesarean section 3 weeks after presentation was followed by the development of left ventricular failure and pulmonary oedema in the early postoperative period. Echocardiography confirmed the diagnosis of aortic dissection and the patient underwent a successful surgical repair.

    Lyme disease is caused by a tick-transmitted spirochete, B. burgdorferi. It can present with both central and peripheral nervous system manifestations, including aseptic meningitis, meningoencephalitis, Bell's palsy and other cranial neuropathies, radiculoneuritis, and myelitis. However, pseudotumor cerebri associated with Lyme disease is rare. Here, we report a eight-year-old girl with the unusual manifestation of pseudotumor cerebri associated Lyme disease. PMID:27411423

    1980-05-01

    Presentation order in paired-comparison testing was varied to measure the impact of primacy versus recency effects on consumer product evaluations. Overall preference and product rating scores were gathered for 1196 male and female Ss aged 13--49 years in two consumer research studies covering 11 taste tests. First position preference bias characterized the findings, lending support to the attention decrement hypothesis or a suggested palate desensitization effect on subsequent taste trial behavior.

    It is very uncommon for urothelial carcinoma to develop in an ureterocele. It is generally discovered in an imaging study or in connection with haematuria. We found very few reports in the literature. Here, we report on the case of a 71-year-old male who initially presented with haematuria and low back pain and who then underwent transurethral resection for an intraureterocele tumour. Pathology confirmed urothelial carcinoma. PMID:26913072

    Neuroblastoma is a neuroectodermal tumor of childhood with poor prognosis and low survival in patients with advanced-stage disease who respond to conventional therapies but unfortunately, often present relapse. Therefore, the search for novel therapeutic strategies is warranted and represents the objective of many investigators. Among the new, innovative approaches, immunotherapy has attracted much interest. However, until recently, little information was available about the immunogenicity of human neuroblastoma.

    1995-04-01

    A 19-year-old baseball player was referred for assessment of recurrent sprains of the right ankle. This was found to be secondary to a palsy of the common peroneal nerve that was compressed by an osteochondroma of the fibular neck. The lesion was resected from the fibula and the patient made a complete recovery. We present this case as an example of a rare underlying problem in a patient who was initially diagnosed as having a sports-related ankle injury.

    Two children are reported with hydrocephalus and aqueduct stenosis who presented with back and limb pains. Neither had the classic symptoms of headache and vomiting. The children had enlarged heads and later developed ataxic gait and papilloedema. The cause of the pains is uncertain but similar symptoms have been reported in subjects with benign intracranial hypertension and may relate to spinal nerve root pouch distension. Operative ventricular drainage resulted in rapid improvement of all symptoms in both children.

    2008-09-01

    We describe a case of mid-aortic syndrome presenting as systemic hypertension in infancy and early childhood. Angiography of the descending and abdominal aorta is the diagnostic test of choice to confirm the diagnosis of mid-aortic syndrome. Severity of hypertension is one of the major factors in determining the timing of intervention. Because of variability in the anatomic extent of mid-aortic syndrome, management options need to be individualized.

    In the "Path to the Future" presentation held at NASA's Langley Center on March 31, 1999, NASA's Administrator Daniel S. Goldin outlined the future direction and strategies of NASA in relation to the general space exploration enterprise. NASA's Vision, Future System Characteristics, Evolutions of Engineering, and Revolutionary Changes are the four main topics of the presentation. In part one, the Administrator talks in detail about NASA's vision in relation to the NASA Strategic Activities that are Space Science, Earth Science, Human Exploration, and Aeronautics & Space Transportation. Topics discussed in this section include: space science for the 21st century, flying in mars atmosphere (mars plane), exploring new worlds, interplanetary internets, earth observation and measurements, distributed information-system-in-the-sky, science enabling understanding and application, space station, microgravity, science and exploration strategies, human mars mission, advance space transportation program, general aviation revitalization, and reusable launch vehicles. In part two, he briefly talks about the future system characteristics. He discusses major system characteristics like resiliencey, self-sufficiency, high distribution, ultra-efficiency, and autonomy and the necessity to overcome any distance, time, and extreme environment barriers. Part three of Mr. Goldin's talk deals with engineering evolution, mainly evolution in the Computer Aided Design (CAD)/Computer Aided Engineering (CAE) systems. These systems include computer aided drafting, computerized solid models, virtual product development (VPD) systems, networked VPD systems, and knowledge enriched networked VPD systems. In part four, the last part, the Administrator talks about the need for revolutionary changes in communication and networking areas of a system. According to the administrator, the four major areas that need cultural changes in the creativity process are human-centered computing, an infrastructure

    Acute otitis externa (AOE) is an infection of the external auditory canal, the auricle, and the outer surface of the tympanic membrane. Although AOE is one of the most common otologic conditions encountered in pediatric population, it is known to primarily affect children older than 2 years. We report a case of AOE caused by Staphylococcus aureus in a 23-day-old neonate. A 23-day-old female infant presented to our neonatology clinic with irritability and discharge from the right ear. There were yellow otorrhea, mild erythema, and edema of right external ear canal. There was no sign of otitis media on otoscopy. The results of laboratory tests were insignificant. The discharge culture grew colonies of methicillin-sensitive Staphylococcus aureus. After 48 hours of treatment with intravenous cloxacillin, significant improvement was observed. The present case highlights an unusual presentation of staphylococcal infection in a neonate. This is the first case of methicillin-sensitive Staphylococcus aureus otitis externa in an immunocompetent newborn. PMID:27703821

    An overview of the CMS upgrade plans will be presented. A brief status of the CMS detector will be given, covering some of the issues we have so far experienced. This will be followed by an overview of the various CMS upgrades planned, covering the main motivations for them, and the various R&D efforts for the possibilities under study. The CMS detector has been working extremely well since the start of data-taking at the LHC as is evidenced by the numerous excellent results published by CMS and presented at this workshop and recent conferences. Less well documented are the various issues that have been encountered with the detector. In the spirit of this workshop I will cover some of these issues with particular emphasis on problems that motivate some of the upgrades to the CMS detector for this decade of data-taking. Though the CMS detector has been working extremely well and expectations are great for making the most of the LHC luminosity, there have been a number of issues encountered so far. Some of these have been described and while none currently presents a problem for physics performance, some of them are expected to become more problematic, especially at the highest Phase 1 luminosities for which the majority of the integrated luminosity will be collected. These motivate upgrades for various parts of the CMS detector so that the current excellent physics performance can be maintained or even surpassed in the realm of the highest Phase 1 luminosities.

    2013-01-01

    The rainforests are the great green heart of Africa, and present a unique combination of ecological, climatic and human interactions. In this synthesis paper, we review the past and present state processes of change in African rainforests, and explore the challenges and opportunities for maintaining a viable future for these biomes. We draw in particular on the insights and new analyses emerging from the Theme Issue on ‘African rainforests: past, present and future’ of Philosophical Transactions of the Royal Society B. A combination of features characterize the African rainforest biome, including a history of climate variation; forest expansion and retreat; a long history of human interaction with the biome; a relatively low plant species diversity but large tree biomass; a historically exceptionally high animal biomass that is now being severely hunted down; the dominance of selective logging; small-scale farming and bushmeat hunting as the major forms of direct human pressure; and, in Central Africa, the particular context of mineral- and oil-driven economies that have resulted in unusually low rates of deforestation and agricultural activity. We conclude by discussing how this combination of factors influences the prospects for African forests in the twenty-first century. PMID:23878339

    Background: Arachnoiditis ossificans (AO) is a rare disorder that was differentiated from leptomeningeal calcification by Kaufman and Dunsmore in 1971. It generally presents with progressive lower extremity myelopathy. Though the underlying etiology has yet to be fully described, it has been associated with various predisposing factors including vascular malformations, previous intradural surgery, myelograms, and adhesive arachnoiditis. Associated conditions include syringomyelia and arachnoid cyst. The preferred diagnostic method is noncontrast computed tomography (CT). Surgical intervention is still controversial and can include decompression and duroplasty or durotomy. Case Description: The authors report the case of a 62-year-old male with a history of paraplegia who presented with a urinary tract infection and dysautonomia. His past surgical history was notable for a C4–C6 anterior fusion and an intrathecal phenol injection for spasticity. A magnetic resonance image (MR) also demonstrated a T6-conus syringx. At surgery, there was significant ossification of the arachnoid/dura, which was removed. After a drain was placed in the syrinx, there was a significant neurologic improvement. Conclusion: This case demonstrates a unique presentation of AO and highlights the need for CT imaging when a noncommunicating syringx is identified. In addition, surgical decompression can achieve good results when AO is associated with concurrent compressive lesions. PMID:26693389

    Lactose intolerance is the most prevalent intestinal malabsorption disorder. After presentation of its history, the author describes the emergence of lactose intolerance during the evolution of species, and the biochemistry of lactose as well as features of human and bacterial lactase enzymes are then described. The unequal distribution of lactose intolerance in different continents and population is discussed, followed by presentation of past and present prevalence data in Hungary. Adult-type hypolactasia is caused by a polymorphism of the MCM6 gene located upstream from the lactase gene on the long arm of the chromosome 2. It can be determined with the polymerase chain reaction. The intestinal symptoms of lactose intolerance are well known, but its extra-intestinal manifestations are less recognised. Invasive diagnostic methods (determination of lactase activity from small intestinal biopsies, lactose tolerance test), are accurate, but have been replaced by the non-invasive methods; their gold standard is the H2 breath test. Genetic testing is being used more and more frequently in Hungary too, and, presumably, the methane breath test will be also available in the near future. Lactose intolerance can be accompanied by inflammatory bowel diseases, coeliac disease and irritable bowel syndrome; it could be established whether this association is causal or not in order to start a correct diet and therapy.

    Rhabdomyolysis is a condition in which striated muscle tissue breaks down rapidly and releases muscular cell constituents into extracellular fluid and the circulation. Renal symptoms, such as acute renal failure, are major complications of rhabdomyolysis. However, no previous report of rhabdomyolysis associated with orbital complication has been issued. Here, we report the first patient of rhabdomyolysis presenting as orbital apex syndrome. A 66-year-old man presented with right periorbital swelling with erythematous patches and conjunctival chemosis. In addition, swelling, redness, and vesicles were observed in both lower legs. He was found in a drunken state with the right side of his face pressed against a table. Ophthalmic examination showed right eye fixation in all directions and ischemic change of retina. Blood testing showed elevated muscle enzyme associated with muscle destruction. And computed tomography of the orbit showed swelling of right extraocular muscles and crowding of right orbital apex. Under a diagnosis of rhabdomyolysis-associated orbital apex syndrome and central retinal artery occlusion, intravenous steroid and antibiotics therapy with intraocular pressure-lowering topicals were begun. Clinical presentation, treatment course, and follow-up are discussed.

    The rainforests are the great green heart of Africa, and present a unique combination of ecological, climatic and human interactions. In this synthesis paper, we review the past and present state processes of change in African rainforests, and explore the challenges and opportunities for maintaining a viable future for these biomes. We draw in particular on the insights and new analyses emerging from the Theme Issue on 'African rainforests: past, present and future' of Philosophical Transactions of the Royal Society B. A combination of features characterize the African rainforest biome, including a history of climate variation; forest expansion and retreat; a long history of human interaction with the biome; a relatively low plant species diversity but large tree biomass; a historically exceptionally high animal biomass that is now being severely hunted down; the dominance of selective logging; small-scale farming and bushmeat hunting as the major forms of direct human pressure; and, in Central Africa, the particular context of mineral- and oil-driven economies that have resulted in unusually low rates of deforestation and agricultural activity.

    Omental fibromatosis (abdominal desmoids) is a rare benign but locally aggressive neoplasm characterized by mass like or infiltrative growth of fibrous tissue. It usually arises from the abdominal wall or the extremities, however rarely it may also arise in the omentum, ileocolic mesentery, transverse or sigmoid mesocolon and ligamentum teres. Here, we present an 18-year-old male, who presented with lower abdominal pain and palpable lump in hypogastric region. Computed tomography of the abdomen showed large heterogeneous mass in lower abdomen, possibly arising from mesentery with regional adenopathy. Patient underwent exploratory laparotomy with a preoperative diagnosis of mesenteric tumour possibly gastrointestinal stromal tumour (GIST). Histopathological examination revealed the lesion as omental fibromatosis. To the best of our knowledge, very few cases of omental fibromatosis are noted in literature. Here, we describe a rare case of giant omental fibromatosis which resembled mesenteric GIST clinically but finally diagnosed as fibromatosis by histomorphology and immunohistochemistry (IHC). The present article describes fibromatosis of greater omentum and the difficulty in preoperative diagnosis, as it is frequently misdiagnosed as GIST. PMID:25859511

    This report describes a patient who presented with pancoast syndrome, secondary to spindle cell sarcoma of the lung. A 56-year man presented with dyspnea, engorged neck veins and bilateral upper limb pitting edema. The patient also had ptosis and miosis in the right eye. Right ulnar nerve palsy with atrophy of hand muscles was seen. His chest X-ray showed bilateral pleural effusion with an opacity involving the apex of the right lung along with mediastinal widening. Echocardiography revealed a pericardial effusion which was drained. The patient's CTscan of chest strongly suspected a malignant mass in right upper lobe with extensive mediastinal lymphadenopathy, pleural metastases and pericardial involvement. He was started on oxygen inhalation, dexamethasone, and clopidogrel. Bronchoscopic biopsy confirmed the diagnosis of spindle cell sarcoma. Meanwhile, he was advised radiotherapy. The tumour was not amenable to surgery. Spindle cell sarcoma is a rare connective tissue tumor that replicates rapidly. To the best of the authors' knowledge, it is hereby reported the first case of spindle cell sarcoma of the lung presenting as Pancoast syndrome. PMID:27504558

  13. The Habitability of Mars: Past and Present

    NASA Astrophysics Data System (ADS)

    McCollom, Thomas M.

    Data collected from recent spacecraft missions to Mars are making it possible to scientifically evaluate whether habitable environments are present, or existed in the past, on the planet. Determining where, when, and how such environments occur will play a crucial role in guiding future exploration efforts. Mars appears to possess the critical elements for life as we know it, including the required chemical elements, energy sources, and the presence ofwater. Identification of potential habitats for life therefore depends on the convergence of these factors under favorable circumstances. Spacecraft observations are more clearly defining the history of water on Mars, and appear to indicate that significant amounts of liquid water have been present at the surface in the past. Most of this water has been lost over time or retreated underground, although there is some evidence for periodic near-surface water in recent eras. If Mars did indeed have a warmer, wetter past, the possibilities for habitable environments were substantial and diverse. On the other hand, the inhospitable nature of the present surface indicates that potential habitats for extant life are much more limited. Nevertheless, habitable environments might exist in the subsurface or at the surface during more favorable climatic periods.

    Three lines of evidence for abrupt tropical climate change, both past and present, are presented. First, annually and decadally averaged δ18O and net mass-balance histories for the last 400 and 2,000 yr, respectively, demonstrate that the current warming at high elevations in the mid- to low latitudes is unprecedented for at least the last 2 millennia. Second, the continuing retreat of most mid- to low-latitude glaciers, many having persisted for thousands of years, signals a recent and abrupt change in the Earth’s climate system. Finally, rooted, soft-bodied wetland plants, now exposed along the margins as the Quelccaya ice cap (Peru) retreats, have been radiocarbon dated and, when coupled with other widespread proxy evidence, provide strong evidence for an abrupt mid-Holocene climate event that marked the transition from early Holocene (pre-5,000-yr-B.P.) conditions to cooler, late Holocene (post-5,000-yr-B.P.) conditions. This abrupt event, ≈5,200 yr ago, was widespread and spatially coherent through much of the tropics and was coincident with structural changes in several civilizations. These three lines of evidence argue that the present warming and associated glacier retreat are unprecedented in some areas for at least 5,200 yr. The ongoing global-scale, rapid retreat of mountain glaciers is not only contributing to global sea-level rise but also threatening freshwater supplies in many of the world’s most populous regions.

    A 31 year old male presented with high grade fever and abdominal pain of 20 days duration. At the age of 9 he had been operated on for a solitary retroperitoneal hydatid cyst and had been asymptomatic until the age of 21 when he sustained a blunt injury to the abdomen. An exploratory laparotomy for splenic rupture revealed multiple intra-abdominal hydatid cysts, which were removed. The patient remained well until the present episode. An ultrasound examination revealed multiple intra-abdominal hydatid cysts. Seven days after admission, the patient developed hydatidemesis (hydatid cysts and membranes in the vomitus) and hydatidenteria (passage of hydatid membranes in the stools), and his pain and fever subsided. A Gastrografin study and a computerized tomography (CT) scan revealed hydatid cysts communicating with the stomach and duodenum. In view of his disseminated recurrent abdominal hydatidosis, he was treated with high dose, long-term albendazole along with regular follow up. This is the first documented case of disseminated abdominal hydatidosis presenting with a cystogastric fistula and hydatidemesis.

    A sphenochoanal polyp is a rare lesion that originates in the sphenoid sinus. It occurs most often in adolescents and young adults. We present what to the best of our knowledge is the first reported case of a sphenochoanal polyp associated with concomitant nasal polyps. The patient was a 54-year-old man who presented with bilateral nasal obstruction, possible obstructive sleep apnea, and an altered voice, all of which had likely been caused by the presence of a massive left sphenochoanal polyp and bilateral grade III anterior and posterior ethmoid polyps. Because the patient had dilated cardiomyopathy, he was not a good candidate for general anesthesia. Therefore, the polyps were removed endoscopically under local anesthesia. The sphenochoanal polyp measured 7.5 cm in its greatest dimension and weighed 41 g. The patient remained symptom-free at the 1-year follow-up. The presentation of a sphenochoanal polyp is similar to that of the more common antrochoanal polyp, but the two can usually be differentiated on computed tomography. Endoscopic sinus surgery allows for complete removal of the polyp, including its site of origin, which minimizes the risk of recurrence.

    We present a case of a relatively common benign tumor that was a diagnostic dilemma because of its atypical appearance in multiple imaging modalities. Our patient was a 22-year-old man who presented with complaint of three months of shin pain with running. The radiographically demonstrated sclerotic lesion in his right tibia initially was thought most likely to be a stress fracture, but on further evaluation, it had features that suggested a subacute osteomyelitis or Brodie's abscess with focal sequestra. It was in fact, biopsy proven to be an osteoid osteoma with multiple, closely adjacent nidi. Its elongate, multicentric, "string of beads" arrangement as well as its intramedullary location is uncommon and it was larger than normally expected. Because of the unusual presentation and appearance of this lesion it caused a diagnostic dilemma. This lesion was evaluated with a full spectrum of modalities including radiographs, CT, MRI, Technetium 99m-MDP bone scan and Indium-111 white blood cell scan. After biopsy achieved a definite diagnosis, this tumor was successfully treated with radiofrequency ablation of all nidi in one session.

    In men harboring prolactinoma the most common symptoms are related to hypogonadism, including decreased libido, erectile dysfunction, and gynecomastia. These men characteristically present with elevated serum prolactin (PRL) levels, suppressed gonadotropins, and low testosterone levels. We studied a group of 11 unique men with prolactinomas presenting with testosterone levels within the normal range (≥2.6 ng/ml; cohort A), and compared them to 11 prolactinoma men with borderline baseline testosterone (2.1-2.5 ng/ml; cohort B) and to a cohort of 34 prolactinoma patients with low testosterone levels (≤2 ng/ml; cohort C). Mean testosterone levels at presentation were 3.91 ± 0.9 ng/ml in cohort A (range, 2.6-5.2 ng/ml), 2.44 ± 0.16 ng/ml in cohort B and 0.96 ± 0.6 in cohort C (p < 0.001). Mean baseline PRL levels were >20 times above normal in cohort A compared to >100 times above normal in cohorts B and C. Symptoms of hypogonadism were present in 55, 64 and 76% of men in groups A, B and C, respectively. There was a trend towards a larger tumor size in the low testosterone group (p = 0.06). Visual fields defects at presentation were more prevalent in this cohort (C). With cabergoline, testosterone level increased from 3.91 to 6.42 ng/ml (Δ = 2.51 ng/ml) in cohort A, from 2.44 to 5.63 ng/ml (Δ = 3.19 ng/ml) in cohort B, and from 0.96 to 3.30 ng/ml (Δ = 2.34 ng/ml) in cohort C (p < 0.05 for each group). Symptoms of hypogonadism improved following treatment in 83% of symptomatic men in cohort A. Normal testosterone does not exclude the likelihood of prolactinoma in men. When treated with cabergoline, testosterone levels in these men can increase higher within the normal range together with clinical improvement. PMID:23756784

    A 70-year-old Caucasian male presented to our clinic for a pruritic eruption progressing over several months. He complained of fatigue with a 20-pound weight loss over the past year. On presentation, the patient had browny-yellow to violaceous, purpuric, macular and papular lesions on the legs, arms, lower abdomen and back. Initial biopsy showed an angiocentric infiltrate with a suggestion of intraluminal proliferation; CD31 and Fli-1 positivity suggested either reactive angioendotheliomatosis or an unusual intravascular histiocytosis. Further excisional biopsies demonstrated perivascular collections of cells with ample cytoplasm, prominent nuclear pleomorphism and mitotic activity. The nuclei demonstrated nuclear folding, grooves and indentations. The atypical cells were S100, CD1a and CD56 positive with immunohistochemistry. A diagnosis of Langerhans cell sarcoma (LCS) was made. LCS is a rare, aggressive malignancy that can involve multiple organs including the skin, lymph nodes, lung, bone marrow, spleen, heart, and brain. The skin and lymph nodes are commonly involved, and the cutaneous presentation varies greatly. Immunohistochemistry characteristically shows CD1a and S100 positivity. CD56 expression is uncommon and often portends a poor prognosis. There is no established treatment of LCS due to its rarity. Surgery, radiation, and chemotherapy have been used with varied outcomes. Our patient was treated with prednisone with improvement of cutaneous disease. He did not develop systemic involvement, but died 1.5 years later from complications associated with heart failure. Langerhans cell sarcoma should be considered when faced with an unusual angiocentric infiltrate in which initial immunohistochemical staining results may be misleading. PMID:27373133
