    The goal of the Information Presentation Directed Research Project (DRP) is to address design questions related to the presentation of information to the crew on flight vehicles, surface landers and habitats, and during extra-vehicular activities (EVA). Designers of displays and controls for exploration missions must be prepared to select the text formats, label styles, alarms, electronic procedure designs, and cursor control devices that provide for optimal crew performance on exploration tasks. The major areas of work, or subtasks, within the Information Presentation DRP are: 1) Controls, 2) Displays, 3) Procedures, and 4) EVA Operations.

  8. 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.

    (Abstract only) The AAVSO is in the process of expanding its education, outreach and speakers bureau program. powerpoint presentations prepared for specific target audiences such as AAVSO members, educators, students, the general public, and Science Olympiad teams, coaches, event supervisors, and state directors will be available online for members to use. 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.

    On November 8, ESO continued its series of presentations in memberstates with an event in Copenhagen. So far events have been organised in Belgium, Finland, Portugal, Sweden, Switzerland and the United Kingdom. The purpose of these presentations is to raise the awareness of ESO amongst decision-makers, academia and the media. Over time, the scope and specific focus of the national events have varied, considering the particular circumstances and the wishes of the national hosts, and accordingly, the presentation in Denmark was primarily oriented towards industry. The meeting was initiated by the Royal Danish Consulate General in Munich in conjunction with the Confederation of Danish Industries and the Ministry for Science, Technology and Innovation. Leading up to the meeting, several articles about ESO had appeared in the Danish press and the 2nd TV Channel featured a report on the ESO projects also in connection with the event.

    PubMed

    Ditisheim, A; Boulvain, M; Irion, O; Pechère-Bertschi, A

    2015-09-09

    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.

As much as preparation and organization are key to the lecture's success, the actual presentation also depends upon the presenter's ability to reach the audience. Teaching is a lively activity. It calls for more than just offering ideas and data to an audience. It calls for direct contact with the audience, effective use of language, capability to use limited time effectively, and the ability to be entertaining. This article offers a structure to effective lecturing by highlighting the importance of voice clarity and speaking speed, approaches to using audiovisual aids, effectively using the audience to the lecture, and ways to be entertaining.

  13. Sirenomelia: a rare presentation.

    PubMed

    Reddy, K Ramesh; Srinivas, S; Kumar, Shiva; Reddy, Surweshwar; Prasad, Hari; Irfan, G M

    2012-01-01

    We are presenting two cases of Sirenomelia (Mermaid Syndrome), which is an extreme example of the caudal regression syndrome. It invariably presents with lower limb fusion, sacral and pelvic bony anomalies, absent external genitalia, imperforate anus, and renal agenesis or dysgenesis. There are approximately 300 cases reported in the literature, 15% of which are associated with twinning, most often monozygotic. The syndrome of caudal regression is thought to be the result of injury to the caudal mesoderm early in gestation. One of our cases survived for 12 days after birth. This new born had an unusually high anorectal anomaly in which the colon was ending at the level of mid transverse colon, fused lower limbs and genital anomalies. Ultrasound of the abdomen revealed horseshoe kidney. Colostomy was performed on day 2 of life. The second case encountered was a stillborn baby on whom an autopsy was performed.

    Chatterjee, Seshadri Sekhar; Talapatra, Devlina; Acharya, Rudra; Sarkhel, Sujit

    2015-01-01

    Psychiatric manifestation of pachygyria, a neuronal migration disorder is rare in literature; rarer if it is bipolar disorder specifically. Here, we report a case of mania and seizure who subsequently diagnosed as pachygyria. Proper literature about pathophysiology is discussed and recently discovered putative genetic role in bipolar disorder explained. This case also emphasis the importance of detailed history taking and imaging investigation even in a pure psychiatric presentation. PMID:26702182

  16. Prematurity: present and future

    PubMed Central

    Tsimis, M. E.; Al-Hamayel, N. Abu; Germaine, H.; Burd, I.

    2014-01-01

    The study of preterm labor and prematurity, as with any medical science, has undergone a major transformation in its approach from an inevitable part of obstetrics with few answers to one in which science has led to knowledge and clinical intervention. Despite these advancements, understanding of preterm labor and prevention of prematurity is still limited. In the current review, we begin the discussion with fetal viability, first from a historical perspective and then from the understanding of this issue from a prospective of various professional organizations. We then present the scope of the problem of preterm birth from various countries including the discrepancy between the US and Europe. We continue with updates on extreme prematurity and outcomes with two longitudinal studies from the past 2 years. We further review available interventions for prematurity and discuss the use of antenatal corticosteroids. First, we examine their use in the context of professional recommendations and then examine the trajectory of their continued use in the late preterm period. We focus on a European-based trial with preliminary results and an ongoing American counterpart. The current knowledge of molecular mechanisms behind preterm labor is presented with a focus on the multiple etiologies of preterm labor, both known and presumed, with updates in the basic science realm. Furthermore, up-to-date studies on prediction of preterm birth and prematurity-related morbidity are presented. PMID:25300768

    NASA Technical Reports Server (NTRS)

    Heap, Erin

    2010-01-01

    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.

    Sotello, David; Test, Victor J.; Lado-Abeal, Joaquin

    2016-01-01

    We describe a 26-year-old man with metastatic choriocarcinoma who presented with hyperthyroidism associated with elevated β-human chorionic gonadotropin (B-HCG) and respiratory failure secondary to diffuse lung metastasis. After the first cycle of chemotherapy, the concentration of B-HCG dramatically decreased and the patient became euthyroid, allowing us to discontinue antithyroid medications. The patient's hyperthyroidism was caused by stimulation of the thyroid gland by high B-HCG levels, as shown by the marked improvement of the patient's thyroid function panel after chemotherapy.

  1. EDITORIAL: Presentation of Manuscripts

    NASA Astrophysics Data System (ADS)

    Hudson, R. P.

    1984-01-01

    We wish to draw the attention of authors to two points concerning the presentation of manuscripts. First, some changes have been made recently in our Instructions to Authors. We have reduced from two to one the number of duplicate copies of the manuscript required, asked for corrected proofs to be returned to the Editor rather than directly to the publishers, clarified that a single set of illustration-photographs will suffice, removed a specific suggestion for a style manual that we had offered for general guidance only, and added an instruction on conventions in spelling and hyphenation. Secondly, authors are required, of course, to present a thorough analysis of their experimental data and to include an estimate of their uncertainty. For this purpose, however, we strongly encourage the authors to follow the recommendations put forward by an international working group [1] to the Comité International des Poids et Mesures (CIPM) and endorsed by that body in its Recommandation 1 (CI-1981). This recommendation has been published by the CIPM [2] and was also summarized recently in this journal [3]. [1] 1981 Metrologia 17 69-74, in particular, see pp 73-74 [2] 1981 ProcA~¨s-Verbaux CIPM 10th Session 49, A1 A12.

  2. Biomarkers present in asphaltenes

    SciTech Connect

    Philp, R.P.

    1985-01-01

    The significance and distribution of biomarkers in sediments, source rocks and crude oils are well documented in the literature. Little attention has been directed towards the biomarkers that are present in the asphaltene fractions of crude oils and source rock extracts. Asphaltene fractions by definition are insoluble in certain solvents and consist of high molecular components which makes them difficult to analyze by techniques commonly used to characterize the soluble extracts. Asphaltenes are ideally suited for analysis by microscale pyrolysis techniques (py) combined with gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Utilization of the multiple ion detection technique in conjunction with the py-GC-MS analyses permits the distribution of the steranes, triterpanes and other biomarker produced by pyrolysis of the asphaltenes to be easily determined. It is proposed in this paper to discuss the pyrolysis of asphaltene from a variety of source rocks and analysis of the biomarkers, released by the pyrolysis. These biomarkers distributions can be used to obtain information on source and maturity of the organic matter in a similar manner to using the soluble biomarkers. It is proposed to discuss the asphaltene biomarker distributions and also to speculate as to why certain biomarkers are present only in the extracts and asphaltenes and not produced by pyrolysis of the kerogens.

  3. Wind for Schools (Presentation)

    SciTech Connect

    Kelly, M.

    2007-06-01

    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.

  4. Acne: clinical presentations.

    PubMed

    Shalita, Alan R

    2004-01-01

    Acne vulgaris, the most common disease of the skin, can be manifested in a wide variety of clinical presentations. As a result of this clinical variation, there are almost as many classifications of acne as there are clinicians with particular interest in the disease. Thus acne has been classified as types I-IV, inflammatory versus noninflammatory, comedonal, comedopapular, papular, papulopustular, pustular, and "cystic" or nodular (even nodular-cystic). For those who are enamored of classification, there are subdivisions of the various categories, including "sandpaper comedones" and microcysts. There is even disagreement as to what constitutes a papule versus a nodule. The classic textbook definition of a nodule refers to lesions 1 cm or larger, but the early investigators of oral isotretinoin defined nodules as 4 mm or larger, and this definition has creeped into many texts, recently clarified by Bologna.(1)

    In 2005, over 150 undergraduate students and first-year graduate students participated in a variety of research programs coordinated by the Jet Propulsion Laboratory Education Office in conjunction with the Caltech Student- Faculty Programs Office. The programs give students the opportunity to conduct research under the guidance of an experienced mentor for a 10-week period. Students gain valuable experience while contributing to the ongoing goals of JPL. Students are required to submit progress reports and an abstract, and to give an oral presentation of their projects to an audience of JPL staff and other students. This set of abstracts provides brief descriptions of the projects that were conducted by these students and their mentors. A schedule of student talks is also included.

  6. Presenting practice financial information.

    PubMed

    Webster, Lee Ann H

    2007-01-01

    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.

  7. Giving effective presentations.

    PubMed

    Englehart, Nadine

    2004-03-01

    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.

  9. Water Past and Present

    NASA Technical Reports Server (NTRS)

    2008-01-01

    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

  10. Presenting the right evidence.

    PubMed

    MacStravic, R S

    1987-09-01

    The primary focus in any marketing communication is its theme--the conclusion that audiences are intended to reach as the result of seeing or hearing the message. Two kinds of conclusions are possible. The first type, factual conclusions, are an awareness and acceptance of objective, verifiable information such as services or technologies offered, location, hours, and charges. The second type of conclusion, an opinion, is a conviction that a given healthcare organization offers a positive subjective attribute, such as compassion, competence, or friendliness. To increase the credibility of subjective attribute claims, marketers can provide seven basic forms of evidence: Statistics; Stories; Exhibits; Demonstrations; Examples; Promises; Testimony. To be effective, the evidence presented must be the right evidence. An organization must determine and respond to what signifies and demonstrates specific subjective attributes to its customers. Organizations must known what quality of patient care means in customer terms, as well as in professional terms. Organizations that deliver the right evidence of quality will enjoy the strongest market positions.

  11. STS-69 postflight presentation

  12. Aqueous cleaning design presentation

    NASA Technical Reports Server (NTRS)

    Maltby, Peter F.

    1995-01-01

    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.

  13. IKONOS: future and present

    NASA Astrophysics Data System (ADS)

    Schaap, Niek

    2003-04-01

    The IKONOS satellite has been operational since January 2000 and was the first commercial satellite collecting imagery with 1 meter resolution. 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.

    Langerhans cell histiocytosis (LCH) is a disease involving the antigen presenting cells, which can range from a single system involvement with an indolent course to a multisystem disease with increased morbidity. We present a rare case of LCH presenting as hypothyroid goitre that was successfully treated as per the LCH III trial protocol with a combination of vinblastine and oral prednisolone. We highlight the need for awareness of this rare presentation of LCH as a painless goitre which is often misdiagnosed as poorly differentiated thyroid carcinoma or overlooked as a benign disease.

  3. Fetal movement and fetal presentation.

    PubMed

    Suzuki, S; Yamamuro, T

    1985-09-01

    Fetal movements were analyzed by means of ultrasonography in an attempt to clarify the causative factor of frank breech presentation. Fetal posture, position, presentation and movements, as well as posture of the extremities and the volume of amniotic cavity were analyzed by ultrasonography in 112 fetuses ranging from 12 to 42 weeks of gestation. There existed three different fetal states: inactivity; slow sporadic movements without changes of presentations; active whole body movements with changes of presentations. It appears likely that version of fetal presentation from breech to cephalic occurs as the fetus tries to accommodate itself to the shape of the uterus during the state of active whole body movements, and the frank breech presentation of the fetus might result when the whole body movements are weak or absent.

  4. No Presentism in Quantum Gravity

    NASA Astrophysics Data System (ADS)

    Wüthrich, Christian

    This essay offers a reaction to the recent resurgence of presentism in the philosophy of time. What is of particular interest in this renaissance is that a number of recent arguments supporting presentism are crafted in an untypically naturalistic vein, breathing new life into a metaphysics of time with a bad track record of co-habitation with modern physics. Against this trend, the present essay argues that the pressure on presentism exerted by special relativity and its core lesson of Lorentz symmetry cannot easily be shirked. A categorization of presentist responses to this pressure is offered. As a case in point, I analyze a recent argument by Monton (Presentism and quantum gravity, 263-280, 2006) presenting a case for the compatibility of presentism with quantum gravity. Monton claims that this compatibility arises because there are quantum theories of gravity that use fixed foliations of spacetime and that such fixed foliations provide a natural home for a metaphysically robust notion of the present. A careful analysis leaves Monton's argument wanting. In sum, the prospects of presentism to be alleviated from the stress applied by fundamental physics are faint.

    One way to build knowledge in nursing is to share research findings or clinical program outcomes. The dissemination of these findings is often a difficult final step in a project that has taken months or years to complete. One method of sharing findings in a relaxed and informal setting is a poster presentation. This method is an effective form for presenting findings using an interactive approach. The milieu of a poster presentation enables the presenters to interact and dialogue with colleagues. Guidelines for size and format require that the poster is clear and informative. Application of design helps to create visually appealing posters. This article summarizes elements of designing and conducting a poster presentation.

    Presentation is one the most common activity performed in various fields of work (e.g. lecturer, employee, manager, etc.). The purpose of presentation is to demonstrate or introduce presenters’ idea to the attendees. Within the given time and specific place, presenters must transfer their knowledge and leave great impression for their audience. Generally, presenters use several handy tools such as mouse, presenter, and webcam to help them to navigate their slides. Nevertheless, some of these tools have several constraints and limitations such as not portable and does not support multimedia. In this research, we develop an application that assist presenters to control their presentation materials by using Microsoft KINECT. In this research, we manipulate colour image, image depth, and the skeleton of the presenters captured by the KINECT. Then, we show the post-process image results into the projector screen. The KINECT has more useful than other tools because it supports video and audio recording. Moreover, it also able to capture presenters’ movement that can be used as an input to interact and manipulate the content (i.e. by touching the projection wall). Not only this application provides an alternative in controlling presentation activity, but it also makes the presentation more efficient and attractive.

  17. Angiomatous Hamartoma - A Rare Presentation

    PubMed Central

    Wadhera, Raman; Kaintura, Madhuri; Bhukar, Sandeep; Pillai, Dheeraj Shashikumar

    2016-01-01

    Eccrine Angiomatous Hamartoma (EAH) is a benign rare skin neoplasm characterised histologically by abnormal proliferation of sweat glands and surrounding capillaries and other dermal elements like fatty lobules and hair. It usually presents at birth or in early childhood in the form of solitary nodules mostly affecting the extremities. Here, we report a case of angiomatous hamartoma over the face which presented as a cystic swelling in preauricular region in a 55-year-old man. The late onset and a rare site for presentation of EAH prompted us to report the case. There is not even a single case of EAH arising in the “preauricular” region, reported. PMID:27790478

    Galactosemia is a treatable metabolic disorder caused by the deficiency of enzyme galactose-1-phosphate uridyl transferase (GALT) and inherited as an autosomal recessive trait. A case of neonate manifesting with recurrent Escherichia coli sepsis is presented here which turned out to be a classic galactosemia. No other common presenting features were observed in this infant except cataract on slit lamp examination. To the best of our knowledge, there is no case of galactosemia reported in literature which presented with recurrent neonatal sepsis without hepatomegaly, hyperbilirubinemia, bleeding disorder, vomiting, diarrhea, failure to thrive, hypoglycemia, coagulopathy, hemolysis or renal tubular acidosis.

    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.

    Jayasinghe, G.; Adam, J.; Abdul-Aal, Y.

    2015-01-01

    Introduction Gall bladder perforation is associated with high mortality rates and therefore must be recognised and managed promptly. We present an unusual presentation of spontaneous gall bladder perforation. Case presentation An elderly lady with multiple medical co-morbidities was admitted with sepsis following a fall. Initial assessment lead to a diagnosis of pneumonia, however a rapidly expanding right flank mass was incidentally noted during routine nursing care. Imaging studies were inconclusive, however incision and drainage of the mass revealed bile stained pus draining cutaneously from an acutely inflamed gallbladder. The patient made a good recovery following surgery, and was discharged with outpatient follow-up. Discussion Despite focussed post-hoc history taking she denied any prodromal symptoms of cholecystitis. In addition to reporting an unusual cause for a common presentation, we highlight the importance of a full body examination in the context of sepsis, regardless of whether the source has been identified. In addition, we advocate that surgical intervention in sepsis should not be delayed by imaging in cases where an abscess is suspected. Conclusions Percutaneous abscesses arising from the gallbladder are a rare but potentially serious consequence of acute cholecystitis, and may present in a wide variety of locations. Therefore it is imperative to conduct a full body inspection in the septic patient, even when a source has been identified. PMID:26686488

  13. Polycythemia vera presenting as acute myocardial infarction: An unusual presentation

    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.

    2014-10-01

    We hereby present the case of a 25-year-old man who presented at the emergency department of Civil Hospital Karachi, Pakistan with signs and symptoms of acute viral hepatitis. Serology tests revealed that the patient was suffering from hepatitis E viral (HEV) infection. Concurrently, the patient was also found to have thrombocytopaenia (TCP). His TCP became better after the resolution of his jaundice, with the patient requiring a transfusion of one mega unit of platelets. After ruling out other common causes of TCP and after a thorough literature search, we concluded that an immune-mediated mechanism secondary to HEV infection might have been the cause behind his low platelet counts. Hence, we propose considering the possibility of HEV infection in patients presenting with acute liver failure and TCP, irrespective of age, gender, and geographical location of the patient.

    PubMed Central

    Proença, Elisa; Godinho, Cristina; Oliveira, Dulce; Guedes, Ana; Morais, Sara; Carvalho, Carmen

    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

    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.

    2013-04-23

    This article reports a case of colovesical fistula presenting with epididymitis. A 75-year-old man with a recent conservatively managed localised diverticular perforation presented to hospital with acute pain and swelling of his left testicle and epididymis. On further questioning, the patient reported passing air in his urine. Urine cultures grew Enterococcus faecalis. Ultrasound scan confirmed a diagnosis of bacterial epididymitis and the patient was treated with intravenous antibiotics. Subsequent CT imaging revealed air in the bladder and a colovesical fistula. The patient went on to have Hartmann's procedure with repair of the bladder defect. This case highlights that: (1) Colovesical fistulae may rarely present with epididymitis. (2) Colovesical fistulae are the most common cause of pneumaturia.

    2009-01-01

    An obese diabetic male presented with self limiting diarrhoea of 1 day duration, which had started after he ate sausages. Examination was unrevealing except for persistent low blood pressure. Computed tomographic (CT) scan, done to rule out retroperitoneal bleed, incidentally showed air in the gall bladder. He underwent emergent cholecystectomy, and a gangrenous gall bladder that grew Clostridium perfringens was removed. Emphysematous cholecystitis is not so infrequent, although only rarely does it present as diarrhoea alone. A high index of clinical suspicion is necessary as even advanced presentation can be subtle and appropriate radio imaging essential. Although abdominal radiograph and ultrasound could be useful, a CT scan is diagnostic. The CT scan and its classical finding confirmed the diagnosis, and it reiterates the importance of timely identification and urgent action, as emphysematous cholecystitis is associated with high mortality.

    Obstructive jaundice as a presentation of abdominal tumors in childhood is extremely rare. To date, only 4 cases of neuroblastoma causing obstructive jaundice at diagnosis have been reported in children. We report a 4-year-old boy who presented to the emergency department with abdominal pain, jaundice, choluria and acholia. A diagnosis of unresectable, nonmetastatic neuroblastoma was made. Chemotherapy reduced the size of the tumor and relieved the symptoms of obstructive jaundice without the need for decompressive surgery. Abdominal tumors should be included in the differential diagnoses of obstructive jaundice in childhood.

    2016-01-01

    Panophthalmitis is one of rare manifestations of tuberculosis described in atypical situations such as children, immune compromised patients, or drug abuse. The present report describes the first case of tubercular panophthalmitis developing after trauma in an otherwise healthy adult patient. A 46-year-old female patient presented with corneal infiltrate and endophthalmitis that developed after an injury to right eye with wooden object. Corneal scrapings and vitreous tap were sterile. The patient did not improve with antibiotics and developed panophthalmitis. On evisceration of the painful blind eye, histopathology showed the presence of granulomatous inflammation and acid-fast bacilli. The patient had no other systemic focus of tubercular infection. The patient was managed with anti-tubercular therapy for 6 months. Atypical presentations of tuberculosis like panophthalmitis pose a difficult problem in diagnosis as well as treatment. Direct inoculation of bacilli during trauma is a rare source of infection. This case report presents unusual development of tubercular panophthalmitis following direct inoculation of bacilli during trauma. Ocular tuberculosis should be considered in differential diagnosis of posttraumatic endophthalmitis and panophthalmitis, especially in endemic regions like India. PMID:27013830

    2017-01-01

    A 25-year-old man presented with a 2-month history of dysphagia and past history of pulmonary and intestinal tuberculosis. A barium swallow showed a point of constriction 42 mm above the gastroesophageal junction. Computed tomography revealed large opacities in bilateral lung fields, encroaching more on the esophagus. The lesion progressively compressed the esophagus as it moved inferiorly. A right posterolateral thoracotomy was performed for sub-anatomical resection of the mass. A biopsy revealed homogenous whirling hyalinized collagen fibers, highly suggestive of pulmonary hyalinizing granuloma, with no evidence of malignancy. Pulmonary hyalinizing granuloma should be considered in the differential diagnosis of longstanding dysphagia.

    Sheehan's syndrome (SS) refers to the occurrence of varying degree of hypopituitarism after parturition (1). It is a rare cause of hypopituitarism in developed countries owing to advances in obstetric care and its frequency is decreasing worldwide. However, it is still frequent in underdeveloped and developing countries. Sheehan's syndrome is often diagnosed late as it evolves slowly (2,3). Reports of psychoses in patients with Sheehan's syndrome are rare. Herein, a case report of psychosis in a 31 year old woman who developed Sheehan's syndrome preceded by postpartum haemorrhage is presented. Treatment with thyroxine and glucocorticoids resulted in complete remission after attaining euthyroid and eucortisolemic state.

    Carcinoid tumors of the ampulla of Vater grow slowly and have an excellent prognosis after complete resection of local disease. Histopathological diagnosis is definitive, and the Whipple's procedure is performed as a standard at the present time, although more novel minimally-invasive techniques may be highly useful for selected patients. While tumor size is not a reliable marker of tumor aggression, it is nonetheless related to lymphatic invasion, hence an accurate diagnosis is important if the patient is to be offered the best option available for the treatment of their disease. Endoscopic ultrasound (EUS) is the technique of choice for presurgical assessment and endocopic excision, as it may rule out vascular and nodal involvement, and establish whether submucosal invasion is present, which precludes endoscopic resection. Local resection has been shown to obtain similar results as compared to CDP in terms of overall survival in patients with small periampullary NETs, with the advantage of significantly lower morbidity in selected cases.

    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.

    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.

    Isolated epididymitis is a very rare presentation of Wegener granulomatosis (WG). Only 1 such case has been previously reported. We report a case of epididymitis in which WG was not suspected clinically or pathologically at orchiectomy, and the patient subsequently developed pulmonary involvement with WG. WG was ultimately diagnosed and treated after lung biopsy several months after the orchiectomy. The retrospective pathologic review of the orchiectomy specimen confirmed the presence of WG in the epididymis; the testicular tissue was not involved.

    Preference judgments about alternative interpretations of unambiguous patterns can be explained in terms of a rivalry between a preferred and a second-best interpretation (cf. Leeuwenberg & Buffart, 1983). We tested whether this second-best interpretation corresponds to a suppressed but concurrently present interpretation or whether it merely reflects an alternative view that happens to be preferred less often. Two patterns were present immediately following each other with a very short onset asynchrony: a complete pattern and one out of three possible subpatterns of it, corresponding to the best, the second best, or an odd interpretation of the complete pattern. Subjects indicated which subpattern was presented by choosing among the three subpatterns shown after each trial. The scores, corrected for response-bias effects, indicated a relative facilitation of the second-best interpretation, in agreement with its predicted "hidden" presence. This result is more in line with theories that capitalize on the quality of the finally selected representation than with processing models aimed at reaching one single solution as fast and as economically as possible.

    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.

    Introduction. Cutaneous paraneoplastic syndromes are a heterogeneous group of skin manifestations that occur in relation to many known malignancies. Paraneoplastic occurrence of SCLE has been noted but is not commonly reported. SCLE association with cholangiocarcinoma is rare. Case Presentation. A 72-year-old man with a history of extrahepatic stage IV cholangiocarcinoma presented with a pruritic rash. Cholangiocarcinoma had been diagnosed three years earlier and was treated. Five months after interruption of his chemotherapy due to a semiurgent surgery, he presented with explosive onset of a new pruritic rash, arthralgias, and lower extremity edema. Physical exam revealed a scaly erythematous rash on his arms, hands, face, neck, legs, and trunk. It was thick and scaly on sun exposed areas. Skin biopsy revealed vacuolar interface dermatitis. Immunofluorescence revealed IgM positive cytoid bodies scattered along the epidermal basement membrane zone. PET-CT scanning revealed metabolically active recurrent disease in peripancreatic and periportal region with hypermetabolic lymph nodes. Oral steroids and new regimen of chemotherapy were started. Rash improved and steroids were tapered off. Discussion. Paraneoplastic syndromes demonstrate the complex interaction between the immune system and cancer. Treatment resistant SCLE should raise a suspicion for paraneoplastic etiology. PMID:26495003

    Urogenital tuberculosis (TB) is a common late manifestation of an earlier symptomatic or asymptomatic pulmonary TB infection. A latency period ranging from 5 to 40 years between the time of the initial infection and the expression of urogenital TB frequently occurs. As one of the most common sites of involvement of extrapulmonary TB, urogenital TB accounts for 15% to 20% of the infections. We present a patient who had culture-negative active tubercular kidney disease due to silent tuberculous infection. Our case demonstrates the limitations of noninvasive testing in establishing the diagnosis of renal tuberculosis.

    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.

    Esthesioneuroblastoma, also called olfactory neuroblastoma, is a rare malignant tumor originating in the olfactory epithelium in the upper nasal cavity with intracranial extension and may also be associated with secondary sinus diseases. Esthesioneuroblastoma has been observed to cause death by distant metastasis or by invasion through the cribriform plate and secondary meningitis. It usually produces nasal obstruction, epistaxis and less commonly anosmia, headache and pain. We report a case of esthesioneuroblastoma in a 50-year-old female who reported with tooth pain as a presenting symptom.

    The future of cardiology rests in the hands and minds of cardiovascular trainees and fellowship programs. Education and training is rapidly changing, and the paradigm of "see one, do one, teach one" has now been replaced by formal assessments of competency, the incorporation of practice improvement and systems-based practice, and a focus on duty hours. To keep up with the expanding knowledge and science in cardiovascular medicine, the cardiology community needs to understand new educational initiatives and formulate pathways to teach, mentor, and educate trainees to become competent cardiovascular specialists. The author highlights some of the present and future issues facing cardiovascular training.

    Tonsilloliths are calcifications within a tonsillar crypt, involve primarily the palatine tonsil caused by dystrophic calcification as a result of chronic inflammation. Tonsilloliths are very uncommon and are microscopic. Tonsillar concretions sometimes produce symptoms which include non-specific chronic halitosis, irritable cough, dysphagia, otalgia and foreign body-like sensation or foul taste. Patients with tonsillolithiasis may also be asymptomatic, with their lesions being discovered incidentally on panoramic radiographs. This article presents an unusual case of multiple bilateral and asymptomatic tonsilloliths which were found during a routine panoramic radiographic examination.

    This invited paper charts the origins and progress of glycoproteomics mass spectrometry research at Imperial College, and in celebration of Donald Hunt's 65th birthday it puts into perspective some of the scientific influence which each group has had on the other over a period of some 35 years. We then describe and illustrate current nano-LC-ES-MS and MS/MS strategies for the structural assignment of N-linked glycosylation in proteins involved in sperm/egg fertilisation. Finally, we present recent progress in the automated interpretation of these glycopeptide data sets, which promises to supersede manual interpretation for many applications.

    Mastocytosis is characterised by clonal proliferation of mast cells in the skin and in various internal organs, and by symptoms related to an acute release of mast cell-derived mediators. In 20-30 % of patients, mastocytosis occurs without the typical skin lesions of urticaria pigmentosa that are usually the first clinical sign of the disease. In these patients, anaphylaxis is often the presenting sign of the disease. We report three cases in which a cardiac emergency (cardiac arrest or ventricular fibrillation) was the first clinical manifestation of anaphylaxis associated with systemic mastocytosis. All patients were men, none of them had previous episodes of anaphylaxis or other mediator-related symptoms, and none had major pre-existing cardiovascular condition. An eliciting factor was identified in one case (a wasp sting), but one was found in the other two. Elevation of the serum tryptase suggested a mastocytosis, which was confirmed by bone marrow biopsy. This case series demonstrates that cardiovascular emergencies may be presenting signs of mastocytosis, and that elevation of serum tryptase after an acute cardiac event, if confirmed under basal conditions, may be useful for diagnosing this disease.

    2007-01-01

    Emphysematous pyelonephritis (EPN) is a serious and often life-threatening condition due to a gas-producing and necrotizing infection involving the renal parenchyma and perirenal tissue. The infection is almost exclusively seen in diabetic patients, and the main feature of its presence is finding gas within the kidney. Patients usually present with fever, chills, flank pain, and dysuria. Laboratory testing usually reveals hyperglycemia, leukocytosis, pyuria, an elevated blood urea nitrogen (BUN) level, and high serum creatinine level. Other, nonspecific symptoms such as abdominal pain, nausea, vomiting, and diarrhea can accompany acute pyelonephritis, as found in the reported case. The appropriate management of such serious infection requires combined medical and surgical treatment. In severe infection, nephrectomy should not be delayed. We report a case of EPN in a diabetic patient who presented with gastrointestinal symptoms. A high index of suspicion, coupled with a good imaging study [preferably computed tomography (CT) scanning] of the abdomen can lead to early diagnosis. Appropriate medical and surgical management have resulted in a successful outcome.

    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.

    Accurate and rapid determination of near-surface wind fields in a complex area (orography, inhomogeneous surface properties) is a challenge for applications like the evaluation of wind energy production, the prediction of pollution transport and hazardous conditions for aeronautics and ship navigation, among others. This work presents a statistical downscaling approach for regional near-surface wind field in the region of southern France (characterized by the presence of major mountain ranges). It is based on generalized additive models (GAM, Salameh et al. 2008), relating large-scale upper air to local-scale surface atmospheric fields. We apply our statistical downscaling model conditionally on regional circulation patterns defined from measurements. Hence, near-surface wind components in southern France are simulated based on large-scale information from ERA-40 reanalyses (1991-2001) and from IPCC scenarios (1991-2001 and 2040-2050). The performances of our method are evaluated, (1) by comparing downscaled wind from ERA-40 and from IPCC, and (2) by comparing them with measurements, for the period 1991-2001. Then, we evaluate the change in regional atmospheric circulations in southern France, by comparing future and present downscaled wind.

    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

    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.

    An increasing number of travelers from western countries visit tropical regions, questioning western physicians on the prophylaxis, the diagnosis and the therapeutic management of patients with travel-associated infection. In July 2014, a French couple stayed for an adventure-travel in Columbia without malaria prophylaxis. A week after their return the woman presented with fever, myalgia, and retro-orbital pain. Three days later, her husband presented similar symptoms. In both patients, testing for malaria, arboviruses and blood cultures remained negative. An empirical treatment with doxycycline and ceftriaxone was initiated for both patients. Serum collected from the female patient yielded positive IgM for leptospirosis but was negative for her husband. Positive Real-Time PCR were observed in blood and urine from both patients, confirming leptospirosis. Three lessons are noteworthy from this case report. First, after exclusion of malaria, as enteric fever, leptospirosis and rickettsial infection are the most prevalent travel-associated infections, empirical treatment with doxycycline and third generation cephalosporin should be considered. In addition, the diagnosis of leptospirosis requires both serology and PCR performed in both urine and blood samples. Finally, prophylaxis using doxycycline, also effective against leptospirosis, rickettsial infections or travellers' diarrhea should be recommended for adventure travelers in malaria endemic areas.

    2013-10-01

    Presentation of a cerebral aneurysm can be incidental, discovered at imaging obtained for unrelated causes, can occur in the occasion of imaging obtained for symptoms possibly or likely related to the presence of an unruptured aneurysm, or can occur with signs and symptoms at the time of aneurismal rupture. Most unruptured intracranial aneurysms are thought to be asymptomatic, or present with vague or non-specific symptoms like headache or dizziness. Isolated oculomotor nerve palsies, however, may typically indicate the presence of a posterior circulation aneurysm. Ruptured intracranial aneurysms are by far the most common cause of non-traumatic subarachnoid hemorrhage and represent a neurological emergency with potentially devastating consequences. Subarachnoid hemorrhage may be easily suspected in the presence of sudden and severe headache, vomiting, meningism signs, and/or altered mental status. However, failure to recognize milder and more ambiguous clinical pictures may result in a delayed or missed diagnosis. In this paper we will describe the clinical spectrum of unruptured and ruptured intracranial aneurysms by discussing both typical and uncommon clinical features emerging from the literature review. We will additionally provide the reader with descriptions of the underlying pathophysiologic mechanisms, and main diagnostic pitfalls.

    A 53-year-old lady presented to A&E with a 3-day history of severe epigastric pain and vomiting. This was preceded by a 3-month history of generalised abdominal discomfort, early satiety and increasing shortness of breath. A CT scan showed a left-sided posterior diaphragmatic defect. Urgent repair of the hernia showed herniation of three-quarter of the stomach, half of the transverse colon, the 13 cm spleen and the pancreas in the chest. There were no postoperative complications. Traumatic diaphragmatic hernias are known to be a complication of major trauma. However, the patient in this case report presented acutely, after mild physical trauma related to using a rowing machine. This exercise, when not performed correctly can raise intra-abdominal pressure. It is plausible that this trauma, although mild, was sufficient in causing the lady's diaphragmatic hernia. This case would suggest that the trauma required to cause a diaphragmatic hernia need not be as severe as originally thought. PMID:23616319

    2010-06-01

    We report the case of a 32-year-old woman with a history of increased sleep need and difficulty waking up; the diagnosis of idiopathic hypersomnia was hypothesized. During ambulatory polysomnography (PSG), the patient presented an episode characterized by loss of consciousness and jerking of the four limbs. A video-PSG monitoring was performed and the patient showed unresponsiveness and drowsiness at 7 a.m. During the episode, EEG showed theta-delta diffuse activity, and blood glucose level was 32 mg dl(-1). The diagnosis of insulinoma was then assumed; CT scan showed a hypodense mass into the pancreatic tail, and a partial pancreasectomy was performed. The described symptoms disappeared, and 5 years later the findings of a complete clinical and neurophysiological examination were negative. The clinical picture of insulinoma presenting with paroxysmal disorders has been previously described; however, whereas hypersomnia is uncommon, in the current case it represents the main symptom. Clinicians should keep in mind that neuroglycopenia should be considered in the differential diagnosis of patients with hypersomnia, particularly if the clinical scenario does not conform to standard criteria.

    The close proximity of the styloid process to many of the vital neurovascular structures in the neck makes it clinically significant. The styloid process is said to be elongated if it is longer than 3.0 cm in length. Anatomical variations are very common and clinical symptoms arising from such variations have to be recognized. Elongated styloid processes may cause chronic throat pain along with foreign body sensation, dysphagia, vague facial pain, and otalgia. Surgical excision of an elongated styloid is considered as a satisfactory treatment for such cases. Here, we present a unique case of bilaterally elongated styloids that could be visualized just by depressing the tongue, when they appeared like the tusks of an elephant in the oropharyngeal region.

    2014-01-01

    Metastases to the female genital tract are rare, with metastatic disease restricted to the uterus being even less frequent. The primary tumor is most often intragenital rather than extragenital. The diagnosis is usually made after occurrence of gynecological symptoms. We describe the case of a 26-year-old female, in whom a curettage for menorrhagia revealed a uterine malignancy, at first thought to be a carcinosarcoma. Biochemistry only showed iron deficiency anemia. Imaging showed discrepant results with liver lesions, suspect of neoplastic or inflammatory disease. She underwent an abdominal hysterectomy and, peroperatively, a frozen section of a mass in the liver hilus demonstrated a cholangiocarcinoma. The diagnosis of a uterine metastasized cholangiocarcinoma was made. We emphasize the fact that uterine metastases have to be excluded in every woman with abnormal uterine bleeding and a personal history of malignancy. However, our case also indicates that gynecological metastatic disease may be the first presentation of an extragenital primary neoplasm. PMID:25610676

    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.

  12. Acute inpatient presentation of scurvy.

    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

    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

    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

    When showing slides with so called "Blue Prints", it is often difficult to explain complex graphics despite the help of a Laserpointer. The Notebook and Videoprojector aid modern presentations in the step by step development of complex graphics. The audience's eyes are directly guided towards the projected image; the attention of the audience is more easily won and held through animation and moving pictures. The central messages of a scientific work can be more simply and clearly conveyed. This method also allows an up-dating of the picture contents at short notice, which is not possible with the common slide. Considering these advantages, modern media should be promoted within the framework of conferences, seminars and further education courses despite the need of greater technical and material equipment.

  17. 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.

    2014-09-01

    Anal fistula is a common benign condition that typically describes a miscommunication between the anorectum and the perianal skin, which may present de novo, or develop after acute anorectal abscess. Athough anal fistulae are benign, the condition can still negatively influence a patient's quality of life by causing minor pain, social hygienic embarrassment, and in severe cases, frank sepsis. Despite its long history and prevalence, anal fistula management remains one of the most challenging and controversial topics in colorectal surgery today. The end goals of treatment include draining the local infection, eradicating the fistulous tract, and minimizing recurrence and incontinence rates. The goal of this review is to ensure surgeons and physicians are aware of the different imaging and treatment choices available, and to report expected outcomes of the various surgical modalities so they may select the most suitable treatment.

    1982-01-01

    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 microbiota that populate the mammalian intestine are critical for proper host physiology, yet simultaneously pose a potential danger. Intestinal antigen-presenting cells, namely macrophages and dendritic cells (DCs), are integral components of the mucosal innate immune system that maintain co-existence with the microbiota in face of this constant threat. Intestinal macrophages and DCs integrate signals from the microenvironment to orchestrate innate and adaptive immune responses that ultimately lead to durable tolerance of the microbiota. Tolerance is not a default response, however, because macrophages and DCs remain poised to vigorously respond to pathogens that breach the epithelial barrier. In this review, we summarize the salient features of macrophages and DCs in the healthy and inflamed intestine and discuss how signals from the microbiota can influence their function. PMID:25976247

    Hadrontherapy is a high-precision technique in cancer radiation therapy, which allows obtaining a superior conformal treatment with respect to photons used in conventional radiation therapy. To reach this ambitious goal without reducing the patient throughput needed in a hospital-based environment, the physical and radiobiological properties of charged hadrons, protons and carbon ions in particular, have to be exploited at best, making use of the most modern technologies issued from research in nuclear and particle physics. In the present days, we are assisting to a continuous technological challenge, leading to the conception and to the development of innovative methods and instruments. In this paper, the most relevant challenges in dose delivery systems, gantries, imaging, quality assurance and particle accelerators are reviewed.

    Many conventional optoelectronic devices consist of thin, stacked films of metals and semiconductors. In this presentation, I will demonstrate how one can improve the performance of such devices by nano-structuring the constituent layers at length scales below the wavelength of light. The resulting metafilms and metasurfaces offer opportunities to dramatically modify the optical transmission, absorption, reflection, and refraction properties of device layers. This is accomplished by encoding the optical response of nanoscale resonant building blocks into the effective properties of the films and surfaces. To illustrate these points, I will show how nanopatterned metal and semiconductor layers may be used to enhance the performance of solar cells, photodetectors, and enable new imaging technologies. I will also demonstrate how the use of active nanoscale building blocks can facilitate the creation of active metafilm devices.

    The important developments in nuclear fuels and their problems are reviewed and compared with the status of present light-water reactor fuels. The limitations of LWR fuels are reviewed with respect to important recent concerns, namely provision of outlet coolant temperatures high enough for use in H 2 production, destruction of plutonium to eliminate proliferation concerns, and burning of the minor actinides to reduce the waste repository heat load and long-term radiation hazard. In addition to current oxide-based fuel rod designs, the hydride fuel with liquid-metal thermal bonding of the fuel-cladding gap is covered. Finally, two of the most promising Generation IV reactor concepts, the very high temperature reactor and the sodium fast reactor, and the accompanying reprocessing technologies, aqueous-based UREX+1a and pyrometallurgical, are summarized. In all of the topics covered, the thermodynamics involved in the fuel's behavior under irradiation and in the reprocessing schemes are emphasized.

Following an on-time launch, the crew of Endeavor are shown setting up a variety of experiments that will operate for much of the mission.

  6. [The present in the brain].

    Murakami, Ikuya

    2013-08-01

    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.

  7. Clinical presentation of hepatitis E.

    PubMed

    Aggarwal, Rakesh

    2011-10-01

    Hepatitis E is a form of acute hepatitis, which is caused by infection with hepatitis E virus. The infection is transmitted primarily through fecal-oral route and the disease is highly endemic in several developing countries with opportunities for contamination of drinking water. In these areas with high endemicity, it occurs as outbreaks and as sporadic cases of acute hepatitis. The illness often resembles that associated with other hepatotropic viruses and is usually self-limiting; in some cases, the disease progresses to acute liver failure. The infection is particularly severe in pregnant women. Patients with chronic liver disease and superimposed HEV infection can present with severe liver injury, the so-called acute-on-chronic liver failure. In recent years, occasional sporadic cases with locally acquired hepatitis E have been reported from several developed countries in Europe, United States, and Asia. In these areas, in addition to acute hepatitis similar to that seen in highly endemic areas, chronic hepatitis E has been reported among immunosuppressed persons, in particular solid organ transplant recipients. HEV-infected mothers can transmit the infection to foetus, leading to premature birth, increased fetal loss and hypoglycaemia, hypothermia, and anicteric or icteric acute hepatitis in the newborns. Occasional cases with atypical non-hepatic manifestations, such as acute pancreatitis, hematological abnormalities, autoimmune phenomena, and neurological syndromes have been reported from both hyperendemic and non-endemic regions. The pathogenesis of these manifestations remains unclear.

    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.

    Background. Pemphigus vulgaris is an autoimmune blistering disease affecting the mucous membrane and skin. In 50 to 70% of cases, the initial manifestations of pemphigus vulgaris are oral lesions which may be followed by skin lesions. But it is unusual for the disease to present with initial and solitary persistent lower lip lesions without progression to any other location. Main Observations. We report a 41-year-old woman with dry crusted lesions only on the lower lip, clinically resembling actinic cheilitis and erosive lichen planus, but histopathological evaluation showed unexpected results of suprabasal acantholysis and cleft compatible with pemphigus vulgaris. We treated her with intralesional triamcinolone 10 mg/mL for 2 sessions and 2 g cellcept daily. Patient showed excellent response and lesions resolved completely within 2 months. In one-year follow-up, there was no evidence of relapse or any additional lesion on the other sites. Conclusion. Cheilitis may be the initial and sole manifestation of pemphigus vulgaris. Localized and solitary lesions of pemphigus vulgaris can be treated and controlled without systemic corticosteroids. PMID:25328720

    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.

This case series from the Tripler Army Medical Center Psychiatry Graduate Medical Education Program presents the extrapyramidal symptoms observed with four different atypical antipsychotic medications. Also reviewed are the mechanisms of action that atypical antipsychotics and first-generation antipsychotics use to treat the symptoms of schizophrenia. Cases reviewed include a schizophrenic male patient whose dose of risperidone was doubled from 6mg to 12mg overnight and developed an acute dystonic reaction; a young male patient with a substance-induced psychosis who unintentionally doubled his ziprasidone dose in 24 hours, resulting in an acute dystonic reaction; a young female patient on paroxetine who also recently started olanzapine and had complaints consistent with akathisia that resolved with treatment; and an adolescent female patient on escitalopram for obsessive-compulsive disorder who after starting aripiprazole developed Parkinsonism. All four cases illustrate that even though atypical antipsychotics are less likely to cause extrapyramidal symptoms than their first generation cousins, the physician should be aware that these symptoms may still occur and need to be treated.

    Toxocariasis is today the most widespread zoonotic, helminthic infection in Russia and other countries of the world. A large population of Toxocara has recently inhabited the urban populations of dogs and cats. Therefore toxocariasis canis and toxocariasis cati have shifted from rural areas to cities and megalopolises where Toxocara canis infestation amounts to as much as 100%, without excluding that in the rural populations of dogs. Due to the fact that the number of dogs and cats has considerably increased (20% of adult dogs and 80% of puppies are infected with Toxocara) in our megalopolises, cities, and urban communities as in foreign countries, this substantially increases the risk of toxacariasis. From the above reasoning, environmental contamination with Toxacara eggs creates an important reservoir of infestation for humans and animals (the contamination rates in different regions of Russia ranges from 1-3 to 50-60%, with the infestation rates of 1 - 10 eggs per 100 g of soil). Human toxocariasis is polymorphic, from its subclinical course to significant organ pathology, and detectable as a manifestation of eosinophilia, fever, hepatomegaly, hyperglobulinemia, lung and central nervous system lesions, myocarditis, and skin rash. The diagnosis of toxocariasis is established by its clinical presentation and serological findings. It is important in the history that children have spent much time with dogs or cats.

    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.

    In this review, we summarize the current "state of the art" of carbapenem antibiotics and their role in our antimicrobial armamentarium. Among the β-lactams currently available, carbapenems are unique because they are relatively resistant to hydrolysis by most β-lactamases, in some cases act as "slow substrates" or inhibitors of β-lactamases, and still target penicillin binding proteins. This "value-added feature" of inhibiting β-lactamases serves as a major rationale for expansion of this class of β-lactams. We describe the initial discovery and development of the carbapenem family of β-lactams. Of the early carbapenems evaluated, thienamycin demonstrated the greatest antimicrobial activity and became the parent compound for all subsequent carbapenems. To date, more than 80 compounds with mostly improved antimicrobial properties, compared to those of thienamycin, are described in the literature. We also highlight important features of the carbapenems that are presently in clinical use: imipenem-cilastatin, meropenem, ertapenem, doripenem, panipenem-betamipron, and biapenem. In closing, we emphasize some major challenges and urge the medicinal chemist to continue development of these versatile and potent compounds, as they have served us well for more than 3 decades.

    Optical trapping has enabled studying a wide variety of questions and systems in chemistry, biology, physics, and materials science. For example, optical trapping has been used to understand hydrodynamic interactions in dilute and dense colloidal fluids and discover connections to granular materials. In this presentation we show that shaped optical fields and gradients can be used to study the electrodynamic interactions amongst nanoparticles (NPs) and drive them into new ordered states. We demonstrate the formation and use of NP-based optical matter to study a range of nonequilibrium phenomena in solution; field-driven barrier crossing phenomena and noise-driven ordering. Optical matter, a material that forms only in the presence of an optical field, involves NP interactions by optical scattering and interference. Metal NPs can be formed into regular arrangements in minimally shaped fields; e.g., in focused Gaussian beams, line traps, and optical ring traps. Inter-particle interactions and motions are also affected when the optical matter is driven. Particles recirculate in an optical ring vortex trap allowing long term measurements to examine rare events. In particular, particles can hop between optical binding sites, move past electrodynamic obstacles or pass each other while moving around the ring. The polarization state of the optical beam can be used to produce periodic variations of the NP electrodynamic interactions. As particles circulate this "noise" causes NP clusters to be less stable as if the temperature of the system is increased. Conversely, we observe noise-driven ordering in dense systems. We will explain these phenomena using simulations and theory.

    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.

    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.

    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.

    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.

    Technology abounds for capturing presentations. However, no simple solution exists that is completely automatic. ProjectorBox is a "zero user interaction" appliance that automatically captures, indexes, and manages presentation multimedia. It operates continuously to record the RGB information sent from presentation devices, such as a presenter's laptop, to display devices, such as a projector. It seamlessly captures high-resolution slide images, text and audio. It requires no operator, specialized software, or changes to current presentation practice. Automatic media analysis is used to detect presentation content and segment presentations. The analysis substantially enhances the web-based user interface for browsing, searching, and exporting captured presentations. ProjectorBox has been in use for over a year in our corporate conference room, and has been deployed in two universities. Our goal is to develop automatic capture services that address both corporate and educational needs.

  7. Presentation skills for the reluctant speaker.

    PubMed

    Garon, J E

    1999-01-01

    Presentation skills are vital to clinical systems managers. This article covers four steps to successful presentations: 1) tailoring for an audience, 2) organizing a presentation, 3) mastering presentation techniques, and 4) creating effective visual aids. Tailoring for the audience entails learning about the audience and matching the presentation to their knowledge, educational level, and interests. Techniques to curry favor with an audience include: establishing common ground, relating through universal experiences, and pushing "hot buttons." Tasks involved in organizing the presentation for maximum audience interest begin with arranging the key points in a transparent organizational scheme. Audience attention is sustained using "hooks," such as graphics, anecdotes, humor, and quotations. Basic presentation techniques include appropriate rehearsal, effective eye contact with an audience, and anxiety-reducing strategies. Visual aids include flip charts, slides, transparencies, and computer presentations. Criteria for selecting the type of visual aids are delineated based on audience size and type of presentation, along with respective advantages and disadvantages. The golden rule for presentations is "Never show a slide for which you have to apologize." Rules to maximize visibility and effectiveness, including use of standard templates, sans serif fonts, dark backgrounds with light letters, mixed cases, and effective graphics, ensure that slides or projected computer images are clear and professional. Taken together, these strategies will enhance the delivery of the presentation and decrease the speaker's anxiety.

  8. Antigen cross-presentation of immune complexes.

    PubMed

    Platzer, Barbara; Stout, Madeleine; Fiebiger, Edda

    2014-01-01

    The ability of dendritic cells (DCs) to cross-present tumor antigens has long been a focus of interest to physicians, as well as basic scientists, that aim to establish efficient cell-based cancer immune therapy. A prerequisite for exploiting this pathway for therapeutic purposes is a better understanding of the mechanisms that underlie the induction of tumor-specific cytotoxic T-lymphocyte (CTL) responses when initiated by DCs via cross-presentation. The ability of humans DC to perform cross-presentation is of utmost interest, as this cell type is a main target for cell-based immunotherapy in humans. The outcome of a cross-presentation event is guided by the nature of the antigen, the form of antigen uptake, and the subpopulation of DCs that performs presentation. Generally, CD8α(+) DCs are considered to be the most potent cross-presenting DCs. This paradigm, however, only applies to soluble antigens. During adaptive immune responses, immune complexes form when antibodies interact with their specific epitopes on soluble antigens. Immunoglobulin G (IgG) immune complexes target Fc-gamma receptors on DCs to shuttle exogenous antigens efficiently into the cross-presentation pathway. This receptor-mediated cross-presentation pathway is a well-described route for the induction of strong CD8(+) T cell responses. IgG-mediated cross-presentation is intriguing because it permits the CD8(-) DCs, which are commonly considered to be weak cross-presenters, to efficiently cross-present. Engaging multiple DC subtypes for cross-presentation might be a superior strategy to boost CTL responses in vivo. We here summarize our current understanding of how DCs use IgG-complexed antigens for the efficient induction of CTL responses. Because of its importance for human cell therapy, we also review the recent advances in the characterization of cross-presentation properties of human DC subsets.

    2017-01-01

    Fibrillary glomerulonephritis (FGN) is a rare primary glomerular disease that commonly presents clinically with hypertension, proteinuria, microscopic hematuria, and varying degree of renal insufficiency. Histologically, FGN can present with different patterns of glomerular injury, more commonly mesangioproliferative, membranoproliferative, and membranous nephropathy. While crescent formation has been described in some kidney biopsy series of FGN, crescentic glomerulonephritis pattern of glomerular injury has been rarely described. Optimal therapy and outcomes in FGN presenting with crescentic GN is not currently known. We report an adult patient who presented with massive proteinuria and severe renal failure. The kidney biopsy revealed crescentic FGN (C-FGN). The patient remained dialysis dependent despite immunosuppressive therapy. We also briefly review FGN, and the few reported cases of C-FGN that presented as rapidly progressive or advanced renal failure in the literature. PMID:28356674

Subsequent investigation showed renal failure and multiple pulmonary nodules. A positive proteinase 3 antineutrophil cytoplasmic antibody test supported the diagnosis of fulminant Wegener's granulomatosis, requiring urgent dialysis, plasma exchange and immunosuppression. This is the first report in the emergency literature of Wegener's granulomatosis presenting as acute epistaxis. Emergency physicians should consider Wegener's granulomatosis in patients with atypical epistaxis. In patients presenting with clinically severe, active disease early proteinase 3 antineutrophil cytoplasmic antibody testing is recommended. PMID:17351208

    Scientific and educational poster presentations in national and international meetings are one of the most effective means of scientific communication. Poster presentations are of particular importance in a mainly visual speciality like radiology, and also play a significant role in continuing medical education in our specialty. However, poster should be no more than an intermediate step on the way to publish our work in a scientific journal. The publication rates of posters prented in courses and conferences is very low in our country. Therefore, we must continue to progress in training in scientific publication, with efforts such as this supplement. This article review how to create an effective poster presentation.

  18. Pemphigus vulgaris presenting as gingival involvement.

    PubMed

    Javali, Mukhatar Ahmed; Zainab, Heena

    2012-09-01

    Pemphigus vulgaris (PV) is an autoimmune blistering disease affecting the mucous membrane and skin. Typically, oral lesions appear before skin lesions, and in a majority of the cases only oral lesions are present. The dentist may then be the first to recognize and diagnose this disease. It is unusual for PV to present over the gingiva as a primary site of involvement. Diagnosis is based on clinical presentation and confirmed by histopathological study. Early diagnosis and management can prevent the uneven life- threatening effects of this potentially chronic mucocutaneous disorder. The case serves to enhance our awareness of the gingiva as a site at which systemic disease can manifest itself.

    2012-04-01

    Alexander disease is a rare leukodystrophy that most often presents in infancy but also includes neonatal, juvenile, and adult variants. Juvenile Alexander disease presents primarily with bulbar symptoms between 2 and 12 years of age. The diagnosis is often suggested by the clinical course and brain magnetic resonance image pattern and then confirmed by the presence of a mutation in the glial fibrillary acidic protein gene. A young girl presented with globus sensation and magnetic resonance imaging of the brain revealed abnormalities mainly involving white matter tracts of the medulla oblongata and cerebellum. The presence of a mutation in the glial fibrillary acidic protein gene confirmed the diagnosis of juvenile Alexander disease. A high index of clinical suspicion is necessary for the diagnosis of late-onset presentations of Alexander disease.

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

    The aim of this study is evaluate the unusual ways of initial presentation of the vestibular schwannomas. We performed a retrospective study of the patients who underwent resection of acoustic neuromas on our service, including for analysis only the cases which initial symptom was not the hearing loss. Tumor size, localization, clinical presentation, and age of the patients were considered. Nine patients present with atypical symptoms. The most common complain in this group were facial paresthesias (22,2 %). None of them complained about other otological symptoms. A significant group of patients did not present with the otological symptoms classically associated with vestibular schwannoma. Clinical knowledge of these kinds of symptoms may lead to earlier detection of these lesions.

    Colloid cysts are benign slow-growing cystic lesions located on the roof of the third ventricle that usually present with symptoms related to gradual rise of intracranial pressure. They mostly remain asymptomatic and sometimes grow progressively and cause diverse symptoms associated with increased intracranial pressure such as headache, diplopia, and sixth cranial nerve palsy. Here we report a 47-year-old female who presented to the emergency department with acute severe headache and nausea/vomiting. On MRI examination acute hydrocephaly due to hemorrhagic colloid cyst was detected. Acute hemorrhage in colloid cysts is extremely rare and may present with symptoms of acute increase in the intracranial pressure. Intracystic hemorrhage is very rarely reported as a complication of colloid cyst presenting with paroxysmal symptoms of acute hydrocephaly. PMID:28210514

    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

    Present detectors for digital radiography are of two classes: real time detectors and storage (non real time) types. Present real time detectors consist of image intensifier tubes with an internal cesium iodide layer x-ray converter. Non real time detectors involve linear sweep arrays or storage detectors such as film. Future detectors discussed here can be of both types utilizing new technologies such as hydrogenated amorphous silicon photodiode arrays coupled to thin film transistor arrays. 17 refs., 10 figs.

    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.

    Scrub typhus is a mite-borne infectious disease caused by Orientia tsutsugamushi, which presents as an acute febrile illness with headache, myalgia, breathlessness, and an eschar, a pathognomonic sign, in a varying proportion of patients. However, this illness can present unusually with fever and severe abdominal pain mimicking acute abdomen. A careful search for an eschar in all patients with an acute febrile illness would provide a valuable diagnostic clue and avoid unnecessary investigations and surgical exploration.

She also complained of tinnitus. Examination of the ears, nose and throat was unremarkable. Flexible nasoendoscopy demonstrated swelling in the postnasal space, which, following biopsy, was shown to be pathognomonic of tuberculosis. This was successfully treated with multidisciplinary input and the patient made a complete recovery.

    We report a case where a patient presented with generalised tonic-clonic seizures secondary to nausea, vomiting and dehydration. She had suffered a postpartum haemorrhage six months previously. On laboratory assessment hyponatraemia and low hormone concentrations suggested pituitary failure. The diagnosis was confirmed by magnetic resonance imaging of the head, which showed a partially empty sella turcica. Given the severity of the morbidity in this case we emphasise that Sheehan's syndrome should be suspected in women presenting with postpartum seizures.

    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. PMID:21941381

  7. 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.

    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.

    Introduction: Pyomyositis of obturator muscles is rare condition. Late presentation with deformities of hip misleads the clinician. Late presentation (6 weeks) of this condition has not been reported earlier. This report highlights this unusual presentation of Pyomyositis of the obturator muscles. Case Report: We are reporting a 14year old female patient presented with limp and pain in hip since 6 weeks. Her hip radiographs were unremarkable. Patient was admitted and MRI done. MRI findings were consistent with obturator pyomyositis. Diagnosis of pyomyositis confirmed by MRI and we performed percutaneous aspiration and drained about 25ml of purulent material mixed with blood. The culture grew Staphylococcus aureus. Patient received intravenous antibiotic for 1week and oral antibiotic for 2weeks. Patient was immobilized in fixed skin traction in Thomas splint for 5days, later gentle mobilization was started. Her condition improved dramatically after aspiration. A follow up MRI done at 3 weeks following aspiration revealed a significant reduction in intramuscular collection of obturator internus and obturator externus. Three weeks following aspiration patient was relieved of the pain and was able to walk normally. At 6 months follow up visit patient was asymptomatic. Conclusion: Late presentation of obturator pyomyositis is rare. We emphasise on careful examination and need for early imaging for diagnosis. Percutaneous drainage results in successful treatment.

    Arens, Yigal; Miller, Lawrence; Sondheimer, Norman

    1988-01-01

    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.

    1989-01-01

    A 69-year-old man presented with a 3-year history of scattered, grouped, asymptomatic follicular papules, pustules, and nodules tending toward coalescence into large geographic aggregates. Repeated cutaneous biopsy specimens showed granulomatous folliculitis with negative Ziehl-Neelsen stains. Finally, biopsy material submitted for mycobacterial culture grew Mycobacterium tuberculosis. No evidence of active systemic tuberculosis was found. The patient had a very rare form of tuberculosis, disseminated lupus vulgaris, presenting with granulomatous folliculitis, which is usually not seen in lupus vulgaris. The lesions resolved after an 18-month course of isoniazid and rifampin. The unusual clinical and histologic presentation as well as occasional partial remissions following a variety of nonspecific empiric therapies delayed diagnosis despite multiple evaluations. This case illustrates the importance of obtaining mycobacterial cultures from skin biopsy specimens in addition to special stains whenever cutaneous tuberculosis is suspected.

  12. Presentation accuracy of Web animation methods.

    PubMed

    Schmidt, W C

    2001-05-01

    Several Web animation methods were independently assessed on fast and slow systems running two popular Web browsers under MacOS and Windows. The methods assessed included those requiring programming (Authorware, Java, Javascript/Jscript), browser extensions (Flash and Authorware), or neither (animated GIF). The number of raster scans that an image in an animation was presented for was counted. This was used as an estimate of the minimum presentation time for the image when the software was set to update the animation as quickly as possible. In a second condition, the image was set to be displayed for 100 msec, and differences between observed and expected presentations were used to assess accuracy. In general, all the methods except Java deteriorated as a function of the speed of the computer system, with the poorest temporal resolutions and greatest variability occurring on slower systems. For some animation methods, poor performance was dependent on browser, operating system, system speed, or combinations of these.

    Melioidosis is common in Australia and Southeast Asia and is increasingly recognized in India. It presents in various forms which are difficult to identify and often mimics suppurative infections, tuberculosis, fungal infections, malignancy and systemic rheumatic diseases. Presentation may vary from local disease to disseminated abscesses, pneumonia and sepsis. Disease is common and severe in diabetics. We describe a case of diabetic man presenting with fever, septic shock, peri-articular nodules, lung opacities and multiple abscesses in muscles for the past 3 months remaining undiagnosed. Autoimmune conditions were ruled out and infection with Burkholderia pseudomallei was suspected. Burkholderia pseudomallei was isolated from blood cultures, confirming the diagnosis. Prolonged treatment with intravenous ceftazidime followed by oral cotrimoxazole led to complete recovery. Awareness of this infection is required by clinicians and microbiologists unfamiliar with the condition to diagnose the disease early to prevent mortality. PMID:27822380

    INTRODUCTION About 5% of ovarian cancers are so poorly differentiated and difficult to classify that they are called undifferentiated carcinomas and usually have disseminated disease at presentation. Extra pelvic debulking it is difficult to complete. PRESENTATION OF CASE We report a case of a rare ovarian tumor presented as a large mesenteric tumor of 14 cm diameter in a 73 years old woman. DISCUSSION Undifferentiated carcinomas are usually large, solid with hemorrhage and necrosis, bilateral and most are difficult to classify histologically. Rarely are pure, generally identified through the extensive sampling of lesions, some other components of surface epithelial carcinoma and usually the predominant element is the latter. Cases with predominantly undifferentiated component are rare. CONCLUSION The treatment and diagnostic approach is the same as for other high-grade epithelial tumors of the ovary, but in this particular case the differential diagnosis and diagnostic approach is that of a mesenteric tumor.

    2016-01-01

    Pityriasis Rosea (PR) is a common skin disease and characterized by generalized scaly eruptions typically on the trunk and proximal extremities. Atypical presentations of PR are common and can be a diagnostic challenge for clinicians. Here we present a case of a 26-year-old female who presented with a sudden onset of several asymptomatic, erythematous and scaly plaques on her trunk. Plaques sized 0.5-1cm in diameter that were distributed unilaterally (right side) on her chest, back and axilla. Atypical cases of PR are fairly common and less readily recognized. Careful history, clinical evaluation and follow-up are important to avoid misdiagnosis of PR and physicians should be aware of PR variants so that appropriate management and reassurance can be offered. For atypical eruptions without a definite diagnosis, it is safer to consider lesional skin biopsy. PMID:28208986

    Georgiev, Tsvetan B.

    This paper presents graphically well known tests about change of population mean and standard deviation, about comparison of population means and standard deviations, as well as about significance of correlation and regression coefficients. The critical bounds and criteria for variability with statistical guaranty P=95 % and P=99 % are presented as dependences on the data number n. The graphs further give fast visual solutions of the direct problem (estimation of confidence interval for specified P and n), as well of the reverse problem (estimation of n, which is necessary for achieving a desired statistical guaranty of the result). The aim of the work is to present the simplest statistical tests in a comprehensible and convenient graphs, which will be always at hand. The graphs may be useful in the investigations of time series in astronomy, geophysics, ecology etc., as well as in the education.

    2015-07-28

    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.

    2015-01-01

    Adrenal hemorrhage (AH) is a relatively uncommon condition in newborns. It may be asymptomatic or may present with flank abdominal mass, anemia, jaundice, or rarely as scrotal bruising or hematoma. We report two cases of AH in neonates; the first presented with scrotal hematoma and the second with adrenal mass associated with hypertension and oliguria, primarily secondary to coincidental renal vein thrombosis. Diagnosis was confirmed by abdominal ultrasound. Patients were managed conservatively with clinical observation and by following hemoglobin and bilirubin levels closely. Both infants were discharged without surgical intervention after several days in the hospital. Clinicians should consider AH when a newborn presents with scrotal bruising or hematoma, unexplained anemia, unexplained jaundice, or flank abdominal mass. Timely ultrasonographic evaluation of both adrenal glands and testes in neonates with scrotal hematoma may spare infants from unnecessary surgical intervention because scrotal hematoma often raises the suspicion of testicular torsion.

    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.

    Metastatic ovarian cancer uncommonly presents with skin metastasis. When present, skin metastases of ovarian cancer are usually localized in the vicinity of the primary tumor. We report a case of a 58-year-old woman with a rapid growing erythematous, well-defined nodule localized on the left nasal ala. A skin biopsy was performed and histopathological and immunohistochemical findings were compatible with a cutaneous metastasis of adenocarcinoma. A systematic investigation revealed a bilateral ovarian cystadenocarcinoma associated with visceral dissemination, likely associated with nose cutaneous metastasis. We report a very uncommon case because of the presentation of ovarian carcinoma as cutaneous metastasis. To our knowledge, this atypical localization on the nose has not been described yet in the literature. PMID:28300910

    There were nine ECE and one EBE presentation at EC-18. Four of the presentations were on various aspects of ECE on ITER. The ITER ECE diagnostic has entered an important detailed preliminary design phase and faces several design challenges in the next 2-3 years. Most of the other ECE presentations at the workshop were focused on applications of ECE diagnostics to plasma measurements, rather than improvements in technology, although it was apparent that heterodyne receiver technology continues to improve. CECE, ECE imaging and EBE imaging are increasingly providing valuable insights into plasma behavior that is important to understand if future burning plasma devices, such as ITER, FNSF and DEMO, are to be successful.

    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.

  4. Remote sensing for oceanography: Past, present, future

    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.

    Complete colonic duplication is a very rare congenital anomaly that may have different presentations according to its location and size. Complete colonic duplication can occur in about 15% of all gastrointestinal duplications. Double termination of tubular colonic duplication in the perineum is even more uncommon. We present a case of a Y-shaped tubular colonic duplication which presented with a rectovestibular fistula and a normal anus. Radiological evaluation and initial exploration for sigmoidostomy revealed duplicated colons with a common vascular supply. Endorectal mucosal resection of theduplicated distal segment till the colostomy site with division of the septum of the proximal segment and colostomy closure proved curative without compromise of the continence mechanism. Tubular colonic duplication should always be ruled out when a diagnosis of perineal canal is considered in cases of vestibular fistula alongwith a normal anus.

    Barral, Duarte C; Brenner, Michael B

    2007-12-01

    The classic concept of self-non-self discrimination by the immune system focused on the recognition of fragments from proteins presented by classical MHC molecules. However, the discovery of MHC-class-I-like CD1 antigen-presentation molecules now explains how the immune system also recognizes the abundant and diverse universe of lipid-containing antigens. The CD1 molecules bind and present amphipathic lipid antigens for recognition by T-cell receptors. Here, we outline the recent advances in our understanding of how the processes of CD1 assembly, trafficking, lipid-antigen binding and T-cell activation are achieved and the new insights into how lipid antigens differentially elicit CD1-restricted innate and adaptive T-cell responses.

  8. Colovesical fistula presenting as Listeria monocytogenes bacteraemia

    PubMed Central

    2015-01-01

    We present a case of colovesical fistula presenting with a clinical syndrome of urosepsis subsequently demonstrated to be due to Listeria monocytogenes bacteraemia. The patient had a history of previous rectal cancer with a low anterior resection and a covering ileostomy that had been reversed 6 months prior to this presentation. L. monocytogenes was also isolated among mixed enteric organisms on urine culture. There were no symptoms or signs of acute gastrointestinal listeriosis or meningoencephalitis. This unusual scenario prompted concern regarding the possibility of communication between bowel and bladder, which was subsequently confirmed with CT and a contrast enema. The patient recovered well with intravenous amoxicillin and to date has declined surgical management of his colovesical fistula. This case illustrates the importance of considering bowel pathology when enteric organisms such as Listeria are isolated from unusual sites. PMID:25827919

  10. 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.

    Even though intervertebral disc degeneration can be found in the natural course of alkaptonuria, detection of the disease by black disc color change in a patient without any other presentation of alkaptonuria is an exceptionally rare condition. We have reported a very rare case of alkaptonuria presented with low back pain and steppage gait in a 51-year-old male with a complaint of chronic low-back pain and steppage gait who was operated on for prolapsed lumbar disc herniation. Intraoperatively his lumbar disk was discovered to be black. The alkaptonuria diagnosis was considered after histopathological examination of the black disc material and elevated urinary concentration of homogentisic acid confirmed the diagnosis. To our knowledge, this presentation has not been reported previously in literature. PMID:27200402

  13. Sheehan syndrome: acute presentation with severe headache.

    PubMed

    Hale, B; Habib, A S

    2014-11-01

    Postpartum headache is a common occurrence with a broad differential diagnosis. Sheehan syndrome, or postpartum pituitary necrosis, is not typically recognized as a cause of postpartum headache. We present a case of Sheehan syndrome that initially presented as severe headache after vaginal delivery complicated by retained placenta and postpartum hemorrhage. The patient was discharged home on postpartum day three but continued to have headaches and returned to hospital on postpartum day six with severe headache, failure to lactate, edema, dizziness, fatigue, nausea and vomiting. Cranial magnetic resonance imaging revealed pituitary infarction consistent with Sheehan syndrome. We discuss the differential diagnosis for postpartum headache, the pathophysiological features of Sheehan syndrome and headache as an atypical acute presentation.

    2009-12-01

    The posters presented at the 6th International Immunoglobulin Symposium covered a wide range of fields and included both basic science and clinical research. From the abstracts accepted for poster presentation, 12 abstracts were selected for oral presentations in three parallel sessions on immunodeficiencies, autoimmunity and basic research. The immunodeficiency presentations dealt with novel, rare class-switch recombination (CSR) deficiencies, attenuation of adverse events following IVIg treatment, association of immunoglobulin (Ig)G trough levels and protection against acute infection in patients with X-linked agammaglobulinaemia (XLA) and common variable immunodeficiency (CVID), and the reduction of class-switched memory B cells in patients with specific antibody deficiency (SAD). The impact of intravenous immunoglobulin on fetal alloimmune thrombocytopenia, pregnancy and postpartum-related relapses in multiple sclerosis and refractory myositis, as well as experiences with subcutaneous immunoglobulin in patients with multi-focal motor neuropathy, were the topics presented in the autoimmunity session. The interaction of dendritic cell (DC)-SIGN and alpha2,6-sialylated IgG Fc and its impact on human DCs, the enrichment of sialylated IgG in plasma-derived IgG, as wells as prion surveillance and monitoring of anti-measles titres in immunoglobulin products, were covered in the basic science session. In summary, the presentations illustrated the breadth of immunoglobulin therapy usage and highlighted the progress that is being made in diverse areas of basic and clinical research, extending our understanding of the mechanisms of immunoglobulin action and contributing to improved patient care.

    Photomigration in azo polymers is an area of research that witnessed intensive studies owing to its potential in optical manipulation; e.g. optical tweezing; the physical mechanism of which remains unsolved since its discovery about two decades ago. In this presentation, a detailed theoretical study that reproduces the phenomena associated with photomigration is presented, including the physical models and the associated master equations. I discuss polarization effects and I give the analytical solutions describing the steady-state and the dynamics of photomigration.

    Isolated female epispadias without bladder exstrophy is a rare congenital anomaly affecting 1 in 484,000 females. The presenting features of female epispadias are urinary incontinence and abnormal anatomical features. A 6-year-old girl presented with primary urinary incontinence who on physical examination had a bifid clitoris and labia minora. The vagina and hymen were normal. Voiding cystourethrogram showed no reflux and a funnel shaped proximal urethra. With the diagnosis of isolated female epispadias, one-stage reconstruction of the urethra, bladder neck, labia minora and clitoris was performed.

    2016-01-01

    Xanthogranulomatous pyelonephritis (XGPN) is a rare form of chronic pyelonephritis with progressive loss of renal function. Commonly, obstructing urinary calculi are seen. It is difficult to differentiate between XGPN and malignancy in many cases, and the diagnosis is usually only confirmed post-operatively upon histopathological examination of the specimen. Surgical treatment is often the main treatment modality due to suspicion for malignancy. Here, we present a case of XGPN that presented with abdominal distension, which was eventually discovered to be due to a preperitoneal abscess. PMID:27915241

    We present a case of a 49-year-old woman with erythema ab igne on her posterior thighs owing to 2-4 hours per day of seat heater use in her car. Erythema ab igne is caused by prolonged exposure to a heat source. It used to be caused mainly by wood stoves used to heat homes. Erythema ab igne is now more often related to other heat sources, including heating pads, laptop computers, and car seat heaters, as in our case. As technology changes, so does the presentation of skin conditions that are related to technology.

    Motor neurone disease (MND) is a chronic, progressive and currently incurable neurodegenerative disorder. This case report discusses an instance of MND presenting initially as polycythaemia, caused via insidious respiratory failure through ventilatory insufficiency. This case aims to improve clinicians' awareness of this atypical presentation and highlights the need for a high index of suspicion of respiratory failure in any patient with polycythaemia. Finally it demonstrates an improvement in quality of life associated with the use of non-invasive ventilation (NIV) in a patient with MND.

    Swellings involving palate can be challenging to diagnose for the clinician as they have wide range of origin which can result from developmental, inflammatory, reactive or a neoplastic process. The clinical presentation of these swellings is similar and difficult to differentiate from each other. So it is important to take proper history from the patient and subject the patient to appropriate laboratory and radiographic investigations and finally biopsy is mandatory for accurate diagnosis. Thus, this article highlights on various common palatal swellings, their clinical presentation, and differential diagnosis helpful for proper diagnosis of swellings associated with palate.

    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

    2014-06-01

    We report a patient with primary leptomeningeal melanocytosis presenting as chronic meningitis. A previously healthy 27-year-old man presented with 2 months of severe headaches and photophobia. A lumbar puncture was notable for a highly elevated cerebrospinal fluid (CSF) protein level without pleocytosis. Imaging at the time of admission suggested only meningitis without the presence of parenchymal lesions. On the basis of the CSF findings, early meningeal biopsy was performed, leading to the diagnosis of a meningeal melanocytic neoplasm. Early meningeal biopsy should be considered in patients with meningitis when the CSF profile suggests the possibility of a central nervous system neoplasm.

    Myelomeningocele with Chiari II malformation and hydrocephalus is a common association seen in infants with a congenital failure of neurulation. Here we report two cases of such an association presenting with different sets of problems. The first patient presented with severe inspiratory stridor due to bilateral abductor vocal cord paralysis, which was relieved completely within 24 h of definitive surgery. The second patient experienced intraoperative cardiac arrest. Definitive surgery was followed after successful cardiopulmonary resuscitation. The cause of the perioperative sequence of events in both cases is attributed to the associated pathologies of Chiari II malformation.

    Cystic lymphangioma usually confined to head and neck is a well-recognized tumor that occurs during childhood. However, a cardiac lymphangioma is exceptionally uncommon and a particularly rare form of disease. We report a case of cystic lymphangioma arising from the right ventricular wall, and presenting as pericardial mass in a young female, who presented with a history of exercise intolerance in the form of breathlessness on exertion and palpitations. The management of such a case was a difficult task; however, she underwent near total resection of the mass, and is doing well for the last 2 years.

    We report a case of a 43-year-old male who initially presented with intermittent testicular pain as the first sign of metastatic stage IV colon cancer. Physical examination revealed a normal penis, scrotum and testes. Magnetic resonance imaging (MRI) of pelvis showed an irregular 3 cm mass of the spermatic cord and right radical inguinal orchiectomy was performed. The pathological diagnosis was metastatic adenocarcinoma. In conclusion, even though metastases to the testes are rare, they should be considered in clinical practice especially in older men who present with a testicular mass or discomfort. PMID:28138654

    A young woman presented with progressive yellowing of her skin over a period of six months. Liver function tests were requested by her general practitioner and the results prompted the Chemical Pathology Department to instigate further tests to reach the final diagnosis. Hypercarotenaemia had caused her yellow skin, and various other biochemical abnormalities pointed towards primary hypothyroidism as an underlying cause. Thyroxine replacement treatment successfully corrected all the biochemical abnormalities including hypercarotenaemia. As far as is known, yellow skin as a sole presenting feature of hypothyroidism is extremely rare. PMID:7962656

A 45-year-old man was diagnosed with Legionnaires' disease 2 days after presenting to hospital with dysuria and right loin pain. He became critically unwell during the hospital admission, with headache, uncontrolled fever, breathlessness, decreasing oxygen saturations and increasing oxygen requirements. A CT pulmonary angiography demonstrated right upper lobar consolidation and Legionella urinary antigen was positive. He was treated with ciprofloxacin and rifampicin and made a full recovery.

    Olanzapine is an atypical antipsychotic drug that is being increasingly used as an intentional overdose. It usually presents with reduced and fluctuating level of consciousness and coma. It may rarely present with muscle toxicity by binding to HT2A receptor in skeletal muscle and increasing its permeability. We report a case of such poisoning which had no obvious symptoms but was brought to emergency due to overdose and was found to have acute muscle toxicity as evidenced by raised creatine phosphokinase (CPK) levels. From this, we also want to emphasize that CPK levels should be checked in all the patient's prescribed olanzapine to look for muscle toxicity.

    Autoerythrocyte sensitization syndrome (AES) was first described by Gardner and Diamond in 1955, when four women with painful bruising were depicted. 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

A stereotactic biopsy showed ductal carcinoma in situ and her estrogen receptor/progesterone receptor/human epidermal growth factor receptor 2-neu receptor were negative. We removed the tumor tissue through lumpectomy and found that the mass was invasive ductal carcinoma. This case report highlights invasive ductal carcinoma, presenting with unilateral nipple discharge.

  16. Primary systemic amyloidosis presenting as constrictive pericarditis.

    2011-01-01

    The most frequent presentation of cardiac amyloidosis is with endomyocardial deposition, and resultant restrictive cardiomyopathy. We present a case of primary systemic amyloidosis causing constrictive pericarditis (CP) and congestive heart failure without clinical evidence of endomyocardial deposition. A comprehensive evaluation by noninvasive and invasive studies facilitated the differentiation of CP from restrictive cardiomyopathy and the patient was effectively treated with pericardectomy. To our knowledge, this is the first documented case of primary systemic amyloidosis causing selective CP with successful antemortem diagnosis and treatment in a young man.

    This presentation describes how you could conceivably allocate variability and reserve requirements, including how to allocate aggregation benefits. Conclusions of this presentation are: (1) Aggregation provides benefits because individual requirements are not 100% correlated; (2) Method needed to allocate reduced requirement among participants; (3) Differences between allocation results are subtle - (a) Not immediately obvious which method is 'better'; (b) Many are numerically 'correct', they sum to the physical requirement; (c) Many are not 'fair', Results depend on sub-aggregation and/or the order individuals are included; and (4) Vector allocation method is simple and fair.

  18. A woman with GN presenting during pregnancy.

    2013-06-01

    The combination of kidney disease and pregnancy has long been recognized as a high-risk situation. When renal disease is recognized for the first time during pregnancy, it presents unique problems for both the obstetric and the renal teams. Particularly difficult can be distinguishing preeclampsia from preexisting kidney disease in women presenting for the first time with hypertension, proteinuria, and reduced GFR during pregnancy. Decision-making regarding performing a kidney biopsy and treatment of glomerular disease during pregnancy is often much more complicated by safety concerns for both the mother and the developing fetus.

  19. Hypopituitarism presenting as congestive heart failure.

    2017-03-03

    Sheehan's syndrome (SS) develops as a result of ischemic pituitary necrosis due to severe postpartum hemorrhage and is characterized by various degrees of hypopituitarism. Although the occurrence of SS is now rare, it should still be considered in any woman with a history of peripartum hemorrhage who develops manifestations of pituitary hormone deficiency any time following the event. Appropriate hormone replacement therapy results in marked clinical improvement. We present an unusual case of SS in a young lady who continued to have normal menstruation after the index event, had two spontaneous pregnancies, and was diagnosed only 11 years later when she presented to us with acute heart failure.

    Blackmore, Lars; Murray, Emmanuell; Scharf, Daniel P.; Aung, Mimi; Bayard, David; Brugarolas, Paul; Hadaegh, Fred; Lee, Allan; Milman, Mark; Sirlin, Sam; Kang, Bryan

    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.

  5. 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.

    Tran, Thi Phuoc Yen; Leduc, Karine; Savard, Martin; Dupré, Nicolas; Rivest, Donald; Nguyen, Dang Khoa

    2013-01-01

    Purpose The porphyrias are a defect in the biosynthesis of heme which can be associated with different neurological symptoms during acute attacks such as peripheral neuropathy, mental disturbance and seizures. So far, there have only been a few case reports of status epilepticus, none of which were of epilepsia partialis continua (EPC). We present here two cases of hereditary coproporphyria (HCP) manifesting EPC as part of the clinical presentation. Method The patients’ medical charts, EEG and imaging studies were carefully reviewed. Results Case 1 is a 49-year-old male who first presented a tonic-clonic seizure. Case 2 is a 30-year-old male who came to the emergency room for a convulsive status epilepticus. Both evolved to EPC over the next days. EPC persisted despite several antiepileptic drug trials. Diagnosis of HCP was confirmed by a high level of urine, fecal and serum porphyrins in both cases and by genetic testing in one. Over the last 3 years, the first patient has continued to present non-disabling EPC and has had four tonic-clonic seizures associated with alcohol consumption. The second patient died from brain edema one month and half after admission. Conclusion Acute porphyrias should be included in the differential diagnosis of new onset status epilepticus, including EPC. Their recognition is important as it modifies significantly patient management, since many anticonvulsants are porphyrogenic. PMID:23898283

    Konopnicki, Sandra; Troulis, Maria J

    2015-12-01

    Almost 2 decades ago, the senior author's (M.T.J.) first article was with our mentor, Dr Leonard B. Kaban, a review article titled "Distraction Osteogenesis: Past, Present, Future." In 1998, many thought it would be impossible to have a remotely activated, small, curvilinear distractor that could be placed using endoscopic techniques. Currently, a U.S. patent for a curvilinear automated device and endoscopic techniques for minimally invasive access for jaw reconstruction exist. With minimally invasive access for jaw reconstruction, the burden to decrease donor site morbidity has increased. Distraction osteogenesis (DO) is an in vivo form of tissue engineering. The DO technique eliminates a donor site, is less invasive, requires a shorter operative time than usual procedures, and can be used for multiple reconstruction applications. Tissue engineering could further reduce morbidity and cost and increase treatment availability. The purpose of the present report was to review our experience with tissue engineering of bone: the past, present, and our vision for the future. The present report serves as a tribute to our mentor and acknowledges Dr Kaban for his incessant tutelage, guidance, wisdom, and boundless vision.

    PubMed Central

    Renner, Christian; Connor, William E.; Steiner, Robert D.

    2016-01-01

    A young girl, age 8.5 years, presented with profound hypercholesterolemia and early xanthomatosis, suggesting homozygous familial (or type II) hypercholesterolemia. The patient’s low density lipoprotein (LDL) receptor function and parental lipoprotein profiles were determined to be normal, prompting revision of the initial diagnosis to pseudohomozygous familial hypercholesterolemia. When she subsequently presented with giant platelets, the case was presented to colleagues on an electronic mailing list. It was recommended that plasma and sterol analysis be performed, which led to a diagnosis of sitosterolemia. The presentation of profound hypercholesterolomia in childhood that ultimately is not attributed as due to homozygous or compound heterozygous defects in the LDL receptor gene has been termed pseudohomozygous familial (or type II) hypercholesterolemia (PHT2HC). Patients diagnosed with PHT2HC subsequently confirmed to have sitosterolemia have been previously reported only rarely. The challenge of achieving accurate specific diagnosis and appropriate workup for these conditions in children is discussed in the context of this rare case and review of the historical literature concerning these conditions.

  6. Psychiatric presentations/manifestations of medical illnesses.

    PubMed

    Castro, Jack; Billick, Stephen

    2013-09-01

    Psychiatry is clearly an integral part of medicine. With a history and physical exam (called the mental status exam in psychiatry), appropriate laboratory or imaging studies, a differential diagnosis is made. If a specific DSM-IV-TR diagnosis is made, then the treatment will naturally follow. The diagnoses are scientifically established with good validity, specificity, sensitivity and inter-rater reliability. Similarly the treatments are established through scientific research. However, sometimes medical illnesses may present with symptoms seemingly pointing to a psychiatric origin. Making a misdiagnosis can be quite problematic and dangerous for the patient. The opposite is also true, that psychiatric illnesses may present with symptoms implying a medical diagnostic origin. Finally, psychiatric patients may have more than one psychiatric diagnosis and in addition, a medical diagnosis too. A high degree of suspicion should always be entertained by the diagnosing physician, psychiatric or non-psychiatric. This paper reviews the literature regarding these situations and then presents several clinical cases where this conundrum was present. Making the correct diagnosis was critical in the successful treatment outcome of each of the clinical cases. When asked to consult on a patient by non-psychiatric physicians, the psychiatrist must be careful to also look for non-psychiatric origins for the referring symptoms. It is important for psychiatrists to build on their medical knowledge from medical school and internship and continue to be kept abreast of confounding symptomatology.

    2009-01-01

    Objective Although crossover trials enjoy wide use, standards for analysis and reporting have not been established. We reviewed methodological aspects and quality of reporting in a representative sample of published crossover trials. Methods We searched MEDLINE for December 2000 and identified all randomized crossover trials. We abstracted data independently, in duplicate, on 14 design criteria, 13 analysis criteria, and 14 criteria assessing the data presentation. Results We identified 526 randomized controlled trials, of which 116 were crossover trials. Trials were drug efficacy (48%), pharmacokinetic (28%), and nonpharmacologic (30%). The median sample size was 15 (interquartile range 8–38). Most (72%) trials used 2 treatments and had 2 periods (64%). Few trials reported allocation concealment (17%) or sequence generation (7%). Only 20% of trials reported a sample size calculation and only 31% of these considered pairing of data in the calculation. Carry-over issues were addressed in 29% of trial's methods. Most trials reported and defended a washout period (70%). Almost all trials (93%) tested for treatment effects using paired data and also presented details on by-group results (95%). Only 29% presented CIs or SE so that data could be entered into a meta-analysis. Conclusion Reports of crossover trials frequently omit important methodological issues in design, analysis, and presentation. Guidelines for the conduct and reporting of crossover trials might improve the conduct and reporting of studies using this important trial design. PMID:19405975

  7. Neuroferritinopathy: Pathophysiology, Presentation, Differential Diagnoses and Management

    PubMed Central

    Kumar, Niraj; Rizek, Philippe; Jog, Mandar

    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

  13. 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.

    PubMed

    Ghoshhajra, Brian B; Techasith, Tust; Choy, Garry; Rojas, Carlos A; Pomerantz, Stuart R

    2011-10-01

    Numerous articles have offered instructions for working with advanced radiology images in Microsoft PowerPoint (Redmond, WA); however, no articles have detailed instructions to do the same on alternative presentation software. Apple Macintosh (Cupertino, CA) computers are gaining popularity with many radiologists, due in part to the availability of a powerful, free, open-source Digital Imaging and Communications in Medicine (DICOM) viewing and manipulating software OsiriX ( http://www.osirix-viewer.com ). Apple's own presentation software, Keynote, is particularly effective in dealing with medical images and cine clips. This article demonstrates how to use Apple's Keynote software to present radiology images and scrollable image stacks, without third-party add-on software. The article also illustrates how to compress media files and protect patient information in Keynote presentations. Lastly, it addresses the steps to converting between PowerPoint and Keynote file formats. Apple's Keynote software enables quick and efficient addition of multiple static images or scrollable image stacks, compression of media files, and removal of patient information. These functions can be accomplished by inexperienced users with no software modifications.

  17. AYURVEDIC CONCEPT OF HRIDROGA ITS PRESENT RELEVANCE

    Murthy, A.R.V.; Singh, R.H.

    1993-01-01

    Hridroga is among those diseases mentioned in Ayurveda where in the description is quite brief and the Ayurvedic view point needs clarification. In view of the increasing evidence of cardiac disorders in the present times this aspect assumes added importance. Among the five types of Hridroga described, in Vatika variety Ayurveda seems to have conceived the disease entity that comes under Ischemic Heart Disease. None of the other Cardiac afflictions seem to have been described under Hridroga. It seems that a few of the presenting features based on this Acute/important/predominant nature have been described Vatika Sotha and Swasa. It looks as though pain dominating heart disease is conceived as Hridroga. When oedema is found to be the main presenting feature it is kept under Vatika sotha and when Dysponea is the main symptom it is described as Swasa. The present article undertakes to discuss this point in detail, based on Ayurvedic concepts as well as current knowledge on medicine. PMID:22556620

    Schreur, Barbara

    1998-01-01

    Originally, this project was to produce an animated Powerpoint presentation of the 'Shuttle Engine and its Software' and to produce a web page with animation including the same materials but with greater detail in the description of the software. The principal emphasis was to be on the web page. Midway through the first year of the project, we were advised by the technical coordinator of this work at MSFC to concentrate on the web page alone. Also, the project was expanded to include a web presentation of the MRECS (Modular Rocket Control System). For the SSME project, the web page presentation has been completed. The integration of the animation into the web page is complete although we have been asked to speed up the animation. Also, the addition of greater detail to the description of the SSME controller software has been added. Much of the work on this program was done by students as their task for their senior project course, the capstone course of their program of study. The students gained a great deal from this project. They have learned to use VISIO, POWERPOINT, PHOTOSHOP, and several web page software packages. The starting point for this project was a PowerPoint presentation by the PI while on a Summer Faculty Fellowship at MSFC. For this project, about half of the drawings of the SSME were improved and about half were completely redrawn. The original still drawings have been animated to illustrate the fuel flow through the SSME system.

  3. Antigen presentation by Hodgkin's disease cells.

    1985-11-01

    The L428 tumor cell line is a long-term tissue culture of Reed-Sternberg cells which was derived from the pleural effusion of a patient with Hodgkin's disease. The L428 cells express all known cell surface antigens, cytochemical staining, and cytologic features of freshly explanted Reed-Sternberg cells. In addition to the previously described HLA-DR cell surface antigens, the L428 cells are now demonstrated to express both DS and SB alloantigens. Thus, the L428 cells express all of the known subclasses of the human immune response genes that are located in the major histocompatibility complex. Furthermore, the L428 cells are capable of presenting soluble antigen to T cells in a genetically restricted fashion. T cell lines were established from normal donors previously immunized with tetanus toxoid. The T cells utilized were incapable of tetanus toxoid-induced proliferation unless antigen-presenting cells were added to the cultures. However, T cells from the two normal donors, which like the L428 cells expressed HLA-DR 5, demonstrated significant proliferative responses when cultured with tetanus toxoid and L428 cells. No proliferative response was observed when the L428 cells were used as antigen-presenting cells for a DR (4,-), DR (2,-) or DR (1,7) T cell line. The tetanus toxoid dose-response curve was similar regardless of whether autologous mononuclear leukocytes or L428 cells were used as antigen-presenting cells. The T cell proliferation induced by soluble antigen was also blocked by anti-HLA-DR antibody. Thus, functionally, Hodgkin's disease may be classified as a tumor of antigen-presenting cells.

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.

    2016-01-01

    Uveal melanoma (UM) is the most common primary intraocular malignancy in adults. The majority of the patients are Caucasian (97.8%) and aged 50–80 years. Choroidal melanoma is the predominant type (86.3%). The clinical presentation may range from no symptoms over various types of visual disturbances to visual loss. Examination includes slit-lamp biomicroscopy, indirect ophthalmoscopy and diagnostic testing, such as B-scan ultrasonography. A number of patients with posterior UM are treated with plaque radiation therapy or enucleation. At present, targeted therapy includes inhibitors of the mitogen-activated protein kinase/mitogen-activated protein kinase kinase signaling pathway. UM disseminates hematogenously, with a high propensity for metastasis to the liver, which the most common site (93% of the cases). While UM is uncommon, a significant proportion of affected patients succumb to this disease and new treatment options to improve patient survival are required. PMID:28101347

    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.

    The area of mitochondrial genomics has undergone unprecedented growth over the past several years. With the advent of the age of omics, investigations have reached beyond the nucleus to encompass the close biological communication and finely coordinated interactions between mitochondria and their nuclear cell mate. Application of this holistic approach, to all metabolic interactions within the cell, is providing a more complete understanding of the molecular transformation of the cell from normal to malignant behavior, before histopathological indications are evident. In this review the surging momentum in mitochondrial science, as it relates to cancer, is described in three progressive perspectives: (1) Past: the historical contributions to current directions of research; (2) Present: Contemporary findings, results and approaches to mitochondria and cancer, including the role of next generation sequencing and proteomics; (3) Future: Based on the present body of knowledge, the potential assets and benefits of mitochondrial research are projected into the near future.

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.

  10. 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.

  11. The clinical presentation of lysosomal storage disorders.

    PubMed

    Wraith, James E

    2004-09-01

    Lysosomal storage disorders (LSDs) are present from conception and produce a clinical phenotype that evolves with time. The introduction of new therapies has made early diagnosis a priority. Clues to the clinical diagnosis of a LSD can be found in the tempo of the illness especially if the central nervous system is involved. Loss of a previously acquired skill (regression) is very characteristic of this group of disorders. Other clinical clues can include a dysmorphic appearance or the presence of characteristic skeletal involvement (dysostosis multiplex), but in some disorders such as Pompe disease or Krabbe disease, these do not occur. The approach to diagnosis has to involve "screening" as there can be considerable overlap in clinical presentation (e.g. Gaucher disease and Niemann-Pick B). Both urine and blood testing are necessary and the majority of diagnoses can now be confirmed at a molecular level. Prenatal diagnosis is possible for all.

    To report the first case of rare isolated breast metastasis from carcinoma gall bladder. Single patient case report. A 35-year-old pre-menopausal female presented with 2 * 2 cm right upper outer quadrant breast lump. Post-mastectomy, histology confirmed it to be metastatic adenocarcinoma positive for both Cytokeratin (CK) 7 and CK20. Past history as told by the patient revealed that 2 years back, cholecystectomy was performed for gall stones, of which no histology reports were present; she had a port site scar recurrence which showed it to be adenocarcinoma. Adjuvant chemotherapy and radiotherapy was advised which the patient did not complete. This is probably the first case reported of isolated breast metastasis from gall bladder carcinoma, diagnosed retrospectively. It also highlights the importance of adjuvant treatment in gall bladder malignancy.

    Pacemaker endocarditis (PME) is a rare but severe complication of endocardial pacemaker implantation. Fungal PME is extremely uncommon. The case of a 66-year-old female patient who was diagnosed as having a pulmonary embolus based upon the patient's clinical presentation and computed tomography angiography findings is presented. Transthoracic echocardiography demonstrated a huge vegetation attached to the pacemaker wire. The pacemaker system was removed surgically during cardiovascular bypass. The vegetation was cultured, the results of which were positive for Aspergillus spp. No risk factors for Aspergillus infection were found in the patient. She was treated with liposomal amphotericin B for 3 weeks, followed by itraconazole for 40 weeks. At 1 year later, the patient remains asymptomatic.

    1986-01-01

    We report 37 patients ranging in age from 1 month to 14 years treated for intestinal malrotation during a five year period. The main presenting features consisted of intermittent attacks of vomiting (15 patients), failure to thrive (seven), and recurrent colicky abdominal pain (seven). The diagnosis was confirmed by gastrointestinal contrast studies in all but three patients. A standard Ladd's procedure comprised the definitive surgical treatment. We emphasise the poor nutritional state at the time of operation (49% of the cases were on or below the third centile). In contrast with neonatal presentation, volvulus of the midgut occurred in only five patients (14%) compared with 68% in neonates with malrotation. There were two deaths in the series. Ninety four per cent of the remaining patients responded favourably to the operative procedure. Malrotation should be considered in the differential diagnosis of a wide variety of symptoms and should be treated promptly once the diagnosis has been confirmed. PMID:3740908

    The porphyrias are inherited disorders of the heme biosynthetic pathway. They are relatively rare and often misdiagnosed; however, acute episodes can be curtailed by early administration of heme arginate. Acute intermittent porphyria is the commonest of acute forms of porphyria. Here, a case is presented of a 23-year-old male with acute intermittent porphyria who came to the emergency clinic with an unexplained abdominal pain. In addition, he exhibited spontaneous hemothorax (two liters of blood accumulated in the chest) as an unusual manifestation of the disease. The most relevant aspects of acute intermittent porphyria are discussed, along with its epidemiology, diagnosis, clinical presentation and treatment. Complexities and diagnostic requirements in making a diagnosis of porphyria are described.

    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.

    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.

    The pleomorphic adenoma of lacrimal gland presents as a painless, progressive, slowly growing supero-temporal swelling with variable proptosis. This tumor is usually found in adults and extremely rare in teenage. We report a case of a 15-year-old boy with pleomorphic adenoma of lacrimal gland which mimicked pseudotumor of orbit due to its presentation as an orbital inflammatory disease and the age distribution. Neuroimaging also suggested pseudotumor and oral steroid was started. But, there was no improvement on steroids and ultrasound guided Fine Needle Aspiration Cytology (FNAC) was performed which suggested Pleomorphic adenoma of the lacrimal gland. En-bloc excision of the mass through antero-lateral orbitotomy was done with satisfactory final outcome The histopathological evaluation was consistent with pleomorphic adenoma of the lacrimal gland.

    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.

    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.

    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

    Wegener's granulomatosis (WG) also known as granulomatosis with polyangiitis (GPA) is an anti-neutrophil cytoplasmic antibody-positive (ANCA) vasculitis which most commonly affects the upper respiratory tract, lungs and kidneys. It is uncommon for colitis to be the primary reason for the first hospital admission related to WG. This case represents one of the few in the literature where colitis is associated with WG and in particular, where colonic involvement was the presenting symptom. The patient presented to hospital with a 3-day history of bloody diarrhoea and was treated for colitis. The disease progressed and during the second admission renal and pulmonary involvement was found. A renal biopsy showed a crescentic change and a CT-confirmed inflammatory changes in the caecum and ascending colon. A diagnosis of WG was made and appropriate treatment initiated. The patient is now in remission. PMID:23436885

    Although exfoliative dermatitis (erythroderma) secondary to malignancy is commonly associated with lymphomas or leukemias, coincident gastrointestinal (GI) malignancy and erythroderma is rare. The authors recently encountered a patient with gallbladder carcinoma presenting as erythroderma. A 77-yr-old Japanese man presented with a 3-mo history of erythematous eruptions with pruritus over almost the entire body. After confirming the diagnosis of erythroderma, asymptomatic gallbladder carcinoma was found. Further investigations detected no malignancies in other organs. An extended cholecystectomy was performed. Histologic examination of resected specimens revealed poorly differentiated adenocarcinoma with negative resection margins. The eruptions with pruritus resolved within 1 wk after the operation. This is the first report, to our knowledge, of coincident biliary malignancy and erythroderma. The experience of the current patient suggests that erythroderma secondary to GI malignancy may resolve spontaneously after curative resection of the tumor.

    Postpartum headache is described as headache and neck or shoulder pain during the first 6 weeks after delivery. Common causes of headache in the puerperium are migraine headache and tension headache; other causes include pre-eclampsia/eclampsia, post-dural puncture headache, cortical vein thrombosis, subarachnoid hemorrhage, posterior reversible leukoencephalopathy syndrome, brain tumor, cerebral ischemia, meningitis, and so forth. Idiopathic intracranial hypertension (IIH) is a rare cause of postpartum headache. It is usually associated with papilledema, headache, and elevated intracranial pressure without any focal neurologic abnormality in an otherwise healthy person. It is more commonly seen in obese women of reproductive age group, but rare during pregnancy and postpartum. We present a case of IIH who presented to us 18 days after cesarean section with severe headache and was successfully managed. PMID:26818168

    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-production efficiency and power-handling capabilities. The status of underlying neutron-producing reactions is summarized. The present and future use of neutron sources in: (i) fundamental neutron-nuclear research, (ii) nuclear-data acquisition, (iii) materials-damage studies, (iv) engineering test, and (v) biomedical applications are discussed. Emphasis is given to current status, near-term advances well within current technology, and to long-range projections.

    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.

    Sheehan's syndrome or Simmond's disease is a rare endocrine disorder seen in clinical practice. The clinical spectrum is diverse and a high index of suspicion together with a good clinical acumen and proper diagnostic approach helps in early diagnosis and prompt treatment of this endocrinopathy. Sheehan's syndrome presenting as a major depressive disorder finds less mention in the literature. The patient discussed here is a 45-year-old female who had been on antidepressants and psychiatry follow up for a long time until she presented to our Out Patient Department (OPD), where she was evaluated in detail and diagnosed as a case of Sheehan's syndrome. The patient is doing well and is on a regular follow-up with us. Further studies are required to demystify the strength of this association in more detail and to elucidate the possible underlying mechanism.

  11. Presentation of Archaeoastronomy in Introductions to Archaeology

    Fisher, Victor B.

    In order to gain insights into how archaeoastronomy is presented (if at all) in introductory archaeology courses at universities, a study of introductory textbooks was undertaken in 2004 and again in 2012. In both instances the results were mixed. The quality of future coverage and the reputation of archaeoastronomy may depend upon archaeoastronomers' ability to confine themselves to good exemplars in the next editions of their books.

    Halitosis is a common condition, whose main etiology does not respond to diseases of the gastrointestinal system. Epiphrenic diverticula are a rare cause of this manifestation, thus they are not frequent and they are usually asymptomatic. However, they may produce symptoms with inability for patient. A patient with severe halitosis is presented. In his study, an epiphrenic diverticulum is diagnosed and the laparoscopic abdominal diverticulectomy is performed with a complete resolution of symptomatology.

    Intelligence, Surveillance, and Reconnaissance (ISR) systems have been in use for thousands of years. Technology and CONOPS have continually evolved and morphed to meet ever-changing information needs and adversaries. Funding sources, constraints and procurement philosophies have also evolved, requiring cost-effective innovation to field marketable products which maximize the effectiveness of the Tasking, Capture, Processing, Exploitation, and Dissemination (TCPED) information chain. This paper describes the TCPED information chain and the evolution of ISR (past, present, and future).

    Kingella kingae is an important and probably under-recognized pathogen in children. It has a predilection for bones, joints and vascular endothelium, but can also cause bacteraemia alone. We present a case of Kingella kingae that manifested itself by presternal soft tissue infection, and suggest that infection of the lower sternum and the junction between the manubrium and the xyphoid process are typical, if not pathognomonic for the organism.

    Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary disease of the cerebral small blood vessels characterized by recurrent ischemic strokes, migraine, and progressive cognitive impairment. In patients with CADASIL, in whom subcortical white matter structures are typically involved, epileptic seizures have been rarely reported as an initial clinical symptom. We describe a patient genetically confirmed as having CADASIL who initially presented with a seizure. PMID:28101484

    Cementoblastoma is a rare benign odontogenic neoplasm which is characterized by the proliferation of cellular cementum. Diagnosis of cementoblastoma is challenging because of its protracted clinical, radiographic features, and bland histological appearance; most often cementoblastoma is often confused with other cementum and bone originated lesions. The aim of this article is to overview/revisit, approach the diagnosis of cementoblastoma, and also present a unique radiographic appearance of a cementoblastoma lesion associated with an impacted tooth.
