    The Balint seminar is used in many family medicine residencies to improve and strengthen the patient-doctor relationship: to make better doctors. Given the lack of Balint leaders in developing countries, the family medicine department at the American University of Beirut (AUB) decided to collaborate with the Medical University of South Carolina (MUSC)-with more than 30 years of experience-to start Balint seminars through videoconferencing. Evaluate the feasibility and effectiveness of Balint seminars conducted through videoconference. A qualitative research using focus group and leaders' feedback to evaluate feasibility of delivery of Balint seminars through videoconference. A Polycom videoconference was set up between residents at AUB and two credentialed Balint leaders at MUSC. The videoconference was composed of two parts: (i) MUSC faculty facilitating Balint seminars; and (ii) MUSC and AUB faculty debriefing following each Balint session. Twenty-six videoconferences were conducted from 15 February 2013 to 31 March 2014. Four themes emerged: technology and connectivity issues, administrative issues, coordination among different time zones and cultural/contextual issues. The videoconferencing with family medicine residents at AUB seemed quite natural and very familiar to the Balint leaders at MUSC. The seminars encouraged the residents to see things from the patients' perspective, inspiring new thoughts and ideas on how to deal with troubling patients. Videoconference Balint seminars offer a promising way to extend the activity to health care providers in other disciplines, states and countries. Moreover, this format has the potential to increase the number of trained Balint leaders. © The Author 2014. Published by Oxford University Press. All rights reserved.

    In the frame of the EC-sponsored TELEMED project, videoconferencing was evaluated as a tool for Remote Expert Consultation (REC) in radiology. The REC environment has been established as a pan-European demonstrator for advanced telecommunication applications in medicine. Five European university hospitals have been interconnected using broadband networks at a speed of 2 Mbit/s and 140 Mbit/s. Videoconference was evaluated in more than 120 sessions. In the experiments, videoconference proved to be a useful tool for teleconsultations, providing a set of requirements identified as indispensable for medical videoconference such as remotely adjustable iris for the document camera are fulfilled. Diagnostic reliability of images recorded with our equipment proved acceptable for digitally acquired images while reliability is limited for conventional images with a high demand of spatial and contrast resolution. Regional spin-off applications that have been established at some participating sites underline the potential of videoconference in health care.

    2008-01-01

    We studied the workings of a rehabilitation team in a videoconference setting to note the pros and cons of videoconferencing in the development of interprofessional care plans (ICPs). We recorded every videoconference held by the teams of the specialized centre and the regional centre for clients with traumatic brain injuries over an 18-month period. Thirteen recorded videoconferences, lasting for 30-98 min, were analysed through an observation grid. On the whole, efficient teamwork was observed: the mean productivity level was 96%, while the percentage of time dedicated to the resolution of technical issues was 2%. During the videoconferences, the clinical coordinator and the client addressed the group most often. One of the most commonly mentioned advantages was the good visual contact provided by videoconferencing. The most often quoted disadvantage was the poor sound quality. The findings from the study support the adoption of videoconferencing and suggest a few guidelines for the development of ICPs.

    Alaskan and Argentinean students as well as arctic and antarctic scientists participated in two International Polar Year (IPY) Pole to Pole Videoconferences in 2007 and 2008. The videoconferences involved elementary, middle and high school students as well as scientists from Alaska, Argentina, Colorado and Washington DC. Alaska students were located in Fairbanks, Healy, Shageluk and Wasilla while the Argentinean students were located in Ushuaia, Argentina, at the southern tip of South America. The purpose was to ask each other and the scientists about local environmental changes, seasonal indicators, and climate change, and how to study the seasonal indicators to determine whether they are being affected by climate change. The videoconferences were followed by web chats and web forums to allow more students in other countries including those in non-polar regions, to interact with scientists, and help students develop ideas for their research projects. These activities are part of the Seasons and Biomes Project that engages K-12 teachers and students in Earth system science investigations as a way of teaching and learning science. This project also provides professional development workshops to teachers and teacher trainers. Seasons and Biomes is one of the projects in the University of the Arctic IPY Higher Education Outreach Cluster Project that has been approved by the IPY Joint Committee. As well, it is part of the GLOBE program, an international hands-on, inquiry-based Earth and environmental science and education program for primary and secondary students in 110 countries. The videoconferences, web chats and forums generated much interest and enthusiasm among students and scientists, and have provided the impetus for student research project initiations and collaborations between schools.

  18. Predicate Argument Structure Analysis for Use Case Description Modeling

    Science.gov (United States)

    Takeuchi, Hironori; Nakamura, Taiga; Yamaguchi, Takahira

    In a large software system development project, many documents are prepared and updated frequently. In such a situation, support is needed for looking through these documents easily to identify inconsistencies and to maintain traceability. In this research, we focus on the requirements documents such as use cases and consider how to create models from the use case descriptions in unformatted text. In the model construction, we propose a few semantic constraints based on the features of the use cases and use them for a predicate argument structure analysis to assign semantic labels to actors and actions. With this approach, we show that we can assign semantic labels without enhancing any existing general lexical resources such as case frame dictionaries and design a less language-dependent model construction architecture. By using the constructed model, we consider a system for quality analysis of the use cases and automated test case generation to keep the traceability between document sets. We evaluated the reuse of the existing use cases and generated test case steps automatically with the proposed prototype system from real-world use cases in the development of a system using a packaged application. Based on the evaluation, we show how to construct models with high precision from English and Japanese use case data. Also, we could generate good test cases for about 90% of the real use cases through the manual improvement of the descriptions based on the feedback from the quality analysis system.

  1. Virtual collaboration: face-to-face versus videoconference, audioconference, and computer-mediated communications

    Wainfan, Lynne; Davis, Paul K.

    2004-08-01

    As we increase our reliance on mediated communication, it is important to be aware the media's influence on group processes and outcomes. A review of 40+ years of research shows that all media-videoconference, audioconference, and computer-mediated communication--change the context of the communication to some extent, reducing cues used to regulate and understand conversation, indicate participants' power and status, and move the group towards agreement. Text-based computer-mediated communication, the "leanest" medum, reduces status effects, domination, and consensus. This has been shown useful in broadening the range of inputs and ideas. However, it has also been shown to increase polarization, deindividuation, and disinhibition, and the time to reach a conclusion. For decision-making tasks, computer-mediated communication can increase choice shift and the likelihood of more risky or extreme decisions. In both videoconference and audioconference, participants cooperate less with linked collaborators, and shift their opinions toward extreme options, compared with face-to-face collaboration. In videoconference and audioconference, local coalitions can form where participants tend to agree more with those in the same room than those on the other end of the line. There is also a tendency in audioconference to disagree with those on the other end of the phone. This paper is a summary of a much more extensive forthcoming report; it reviews the research literature and proposes strategies to leverage the benefits of mediated communication while mitigating its adverse effects.

  2. Managing context for Internet videoconferences: the multimedia Internet recorder and archive

    Multimedia objects are difficult to query since much of the content of the object is beyond the interpretive capabilities of a computer. State-of-the-art multimedia content-based retrieval systems focus on post mortem analysis of the underlying data objects to derive semantic information. With the emergence of inexpensive I/O technology we can shift some of the burden of this content analysis to `smart' devices that can capture context information about a multimedia object. Context information includes the geographical location an object is created or used, identities of users, activities of users and other applications, etc. Such information can be used to index the multimedia objects to perform content-based queries with minimal signal processing. We are concerned with the design and implementation of a context-based retrieval system for IP-multicast videoconferences. The Multimedia Internet Recorder and Archive (MIRA) models a videoconference as a Bayesian network that describes bounds on `cost' and `reliability' for a recording task. Context about a videoconference is derived from monitoring the RTCP control channel and messaging events that occur among meeting participants. MIRA creates an index of context information as an XML document that is used by clients to visualize, browse, and retrieve multimedia objects. MIRA also creates event-based transcripts as summaries of meetings. These transcripts are available over the WWW.

  3. Silicon in 'pure gold'? Theoretical contributions and observations on teleanalysis by videoconference.

    Science.gov (United States)

    Gutiérrez, Lucio

    2017-08-01

    Ideas about psychoanalysis via videoconference-videoconference teleanalysis (VT)-are presented with the general understanding that these settings produce a twofold split between various degrees of recognition/negativisation of the absence of the other, on one hand, and the expectation of physical co-presence, on the other. This split has been put forward as dismantling the here, now, with me pre-reflexive unity of the analytic experience. This article suggests that both members of the analytic dyad will seek to reappropriate the experience through a forced ego integration that interferes with accessing states of unintegration in the analytic treatment and produces subtle alterations to symbolisation work. The effort to overcome this condition is illustrated with clinical vignettes and therapists' comments about feelings of inauthenticity and discontent when trying to sustain evenly-suspended attention, as well as in the perception of a form of flattening of the alive nature of speech. However, this is not a constant for all VT, and mutual understanding can be an important mitigating feature. The focus of the discussion should be on the capacity of the analytic dyad to overcome such a split and not on a direct extrapolation of the perceptual limitations of VT to possible effects on transference / countertransference.

    Web-based interviewing may be an effective element of a medical school's larger approach to promotion of holistic review, as recommended by the Association of American Medical Colleges, by facilitating the feasibility of including rural and community physicians in the interview process. Only 10% of medical schools offer videoconference interviews to applicants and little is known about the impact of this interview modality on the admissions process. This study investigated the impact of overall acceptance rates using videoconference interviews and face-to-face interviews in the medical school selection process using an equivalence trial design. The University of New Mexico School of Medicine integrated a videoconferencing interview option for community and rural physician interviewers in a pseudo-random fashion during the 2014-2016 admissions cycles. Logistic regression was conducted to examine whether videoconference interviews impacted acceptance rates or the characteristics of accepted students. Demographic, admissions and diversity factors were analyzed that included applicant age, MCAT score, cumulative GPA, gender, underrepresented in medicine, socioeconomic status and geographic residency. Data from 752 interviews were analyzed. Adjusted rates of acceptance for face-to-face (37.0%; 95% CI 28.2, 46.7%) and videoconference (36.1%; 95% CI 17.8, 59.5%) interviews were within an a priori ± 5% margin of equivalence. Both interview conditions yielded highly diverse groups of admitted students. Having a higher medical college admission test score, grade point average, and self-identifying as disadvantaged increased odds of admission in both interview modalities. Integration of the videoconference interview did not impact the overall acceptance of a highly diverse and qualified group of applicants, and allowed rural and community physicians to participate in the medical school interview process as well as allowed campus faculty and medical student committee members

    Malaria is the most common protozoan infection in the world. In 1964, it was considered eradicated in our country, all the new cases being declared as imported, the present migratory and tourism factors obviously having increased the incidence. We analyzed 49 cases of imported malaria diagnosed at "Hospital de Mar" in Barcelona between 1976 and 1987. 14 patients were emigrants from endemic areas. Africa as the continent (73.4%), and equatorial Guinea as the country (44.8%) being the geographical areas most frequently found as sources of the cases. Only 40% of tourists took chemoprophylaxis measures and only half of them did it correctly. The most usual plasmodium found was the P. Falciparum (21 cases). The conclusion is evident, it is necessary to create a greater awareness in our area, improving the information for travellers to tropical countries applying sanitary controls to immigrants who come from endemic areas.

    Brucellosis is a zoonosis caused by Brucella spp. It may be acquired by consuming unpasteurized dairy products. Brucellosis has a low incidence in Chile, thus, we have a scarce data. To report and to characterize the first series of clinical cases of adult patients diagnosed with brucellosis in Chile. We describe a series of 13 clinical cases in patients diagnosed between 2000 and 2016 in three different centers in the Metropolitan Region, Chile. A retrospective analysis was performed on clinical presentation, laboratory, antibiotic treatment, morbidity and mortality. The mean age was 50 years old. Eight cases had a record of consumption of unpasteurized dairy products. The most frequently reported complaints were fever. The most frequent focal point involved was the spine. Only one patient had a positive blood culture, while the diagnosis was made using serological techniques in the other part of the group. The most indicated antibiotic regimens were doxycycline-rifampicin and doxycycline-gentamicin. The hospital stay was 20 days approximately as an average. Clinical cure was achieved in all cases. Brucellosis is an infrequent zoonosis in Chile, and it produces a nonspecific clinical picture, so it is necessary to have high suspicion to make the diagnosis based in the antecedent of consumption of unpasteurized dairy or raw meat.

    Telemedicine has revolutionised the ability to provide care to patients, relieve professional isolation and provide guidance and supervision to junior medical officers in rural areas. This study evaluated the Townsville teleoncology supervision model for the training of junior medical officers in rural areas of North Queensland, Australia. Specifically, the perspectives of junior and senior medical officers were explored to identify recommendations for future implementation. A qualitative approach incorporating observation and semistructured interviews was used to collect data. Interviews were uploaded into NVivo 10 data management software. Template analysis enabled themes to be tested and developed through consensus between researchers. One tertiary level and four secondary level healthcare centres in rural and regional Queensland, Australia. 10 junior medical officers (Interns, Registrars) and 10 senior medical officers (Senior Medical Officers, Consultants) who participated in the Townsville teleoncology model of remote supervision via videoconference (TTMRS) were included in the study. Perspectives on the telemedicine experience, technology, engagement, professional support, satisfaction and limitations were examined. Perspectives on topics raised by participants were also examined as the interviews progressed. Four major themes with several subthemes emerged from the data: learning environment, beginning the learning relationship, stimulus for learning and practicalities of remote supervision via videoconference. While some themes were consistent with the current literature, new themes like increased professional edge, recognising non-verbal cues and physical examination challenges were identified. Remote supervision via videoconference provides readily available guidance to trainees supporting their delivery of appropriate care to patients. However, resources required for upskilling, training in the use of supervision via videoconference, administration

    2009-01-01

    Full Text Available Erythema nodosum (EN is a dermatosis of unclear etiology, which is characterized by vascular lesion of the skin; it shows itself as hard painful nodes occurring in the derma or subcutaneous fat on the shins and thighs. EN has been described in many chronic infectious processes with some features of its clinical course. In most cases, the disease is regarded as a nonspecific immunoinflammatory response to a wide spectrum of etiological factors, including that in gestation, which presents certain problems in curing the patient. The example given below supports the need for timely testing for infectious markers in pregnancy and, in case of evolving EN, for using not only nonsteroidal anti-inflammatory drugs, but also pathogenetic treatment.

    Abdominal gunshot wound (AGSW) is a trauma emergency. The purpose of this report is to describe our experience with managing AGSW largely without modem investigational modalities. Data was collected retrospectively by reviewing the surgical reports and clinical charts of patients admitted to live hospitals dealing with AGSW over a 5-year period. Incomplete files and wounds not involving the abdomen were not included. A total of 86 files were analyzed. Patients ranged in age from 10 to 63 years ivith mean age of 32 years and a sex ratio of 5.5. Most patients (87%) underwent surgical exploration. Laboratory revealed no lesions in 22.5% of cases, minor lesions in 9.5% and major lesions justifying surgical repair in 68%. A total of 86 visceral lesions were found in the patients who underwent surgical exploration. The lesion involved the small intestine in 31.5% of case, colon in 24.5%, liver in 23.5%, spleen in 7%, stomach in 6%, and uterus in 2%. The kidney, pancreas, mesenteries, large momentum, and transverse mescaline each accounted for 1% of lesions. Conventional operative techniques were used with a mortality of 5.5% and morbidity of 4%. Based on our findings we conclude that when investigational tools (CT-scan, peritoneal lavage and laparoscopy) are unavailable prolonged watchful waiting increases the risk of mortality and morbidity in patients presenting AGSW associated with suspicious clinical signs. Prompt surgical treatment improves prognosis but is associated with a high rate of cases showing no lesions.

    Granulomatosis with polyangiitis (GP) is a necrotizing vasculitis of unknown etiology that involves small and medium caliber vessels. It is associated with anti neutrophil cytoplasm antibodies (ANCA). It most often affects the respiratory tract and the kidneys and its most important pathologic feature is the presence of necrotizing granulomas. To detail the features of 15 patients with GP diagnosed in a university referral center. Retrospective study: between 1984 and 2009, 15 patients with GP were diagnosed in our center. Epidemiological, clinical, laboratory test as well as pathologic studies and treatment were retrospectively analyzed. Biopsy diagnosis of GP was considered as an inclusion criterion. Fifteen patients were diagnosed: 12 men and 3 women. Mean age at diagnosis: 52.2 years (14-78). 12 patients had a history of smoking. A biopsy was diagnostic in all patients. ANCA were positive in 11 cases, 6 had a cytoplasmic c-ANCA pattern. All patients had pulmonary involvement and seven (40%) had renal involvement. All patients received intravenous glucocorticoids and cyclophosphamide as induction therapy. During the disease progression 5 patients died. The clinical features of this series do not differ from those described by other authors. However, a history of smoking is more common than expected. Frequently used drugs were glucocorticoids and cyclophosphamide (oral and pulse therapy). The course was usually unfavorable, with outbreaks or complications due to immunosuppression, except for those with limited forms. Immunosuppressive therapy should be maintained indefinitely in most cases. Copyright © 2010 Elsevier España, S.L. All rights reserved.

    Full Text Available Farber disease (lipogranulomatosis, OMIM 228000 — is extremely rare autosomal-recessive disorder from group of lysosomal storage disorders, due to deficiency of acid ceramidase activity enzyme. Farber disease has a lot of clinical masques and resembles to different inflammatory disorders, such as juvenile arthritis, chronic urticaria, larynx papillomatosis and others. Most effective therapeutic method is bone marrow transplantation, which leads to minimization of disabling and improve quality of life. Currently a medication for enzyme replacement therapy of Farber disease is produced and it is under the clinical trials. We describe clinical course of two patients with different types of Farber disease. First case — 10 years old boy with II–III type of disease, and second — with fatal outcome in the age of 4 years 3 months of boy with I (classical type of Farber disease.

    Radiation proctitis, is a relatively frequent complication resulting from the direct or collateral irradiation of the rectum in radiotherapy treatment for genito-urinary or anorectal malignancies. The main symptoms are diarrhoea, tenesmus, proctorrhagia, anal pain, mucorrhoea and faecal incontinence. The evolution of chronic radiation proctitis requires treatment for related anaemia, anal incontinence and micturition disorders. The approach and type of treatment depend on the severity of the symptoms and on the endoscopic aspect, in relation to the response to previous medical therapy performed. In our experience, endoscopic treatment is the best choice in the presence of ongoing bleeding and the possible development of severe anaemia. The surgical option is mandatory in patients at high risk of sepsis, requiring a faecal diversion constructed using the Hartmann technique. We report two cases, observed during the last two years, one treated with endoscopic bipolar coagulation and the other with a double urinary and faecal diversion.

    Necrobiosis lipoidica (NL) is a chronic idiopathic granulomatous disease considered to occur in association with diabetes mellitus. Data on the frequency of this association, however, are inconsistent. Our aim was to retrospectively analyze the clinical characteristics of patients diagnosed with NL at our hospital and to investigate the association with diabetes mellitus and other diseases. We performed a chart review of all patients with a clinical and histologic diagnosis of NL treated and followed in the dermatology department of Hospital de Bellvitge in Barcelona, Spain between 1987 and 2013. Thirty-five patients (6 men and 29 women with a mean age of 47.20 years) were diagnosed with NL in the study period. At the time of diagnosis, 31 patients had pretibial lesions. Thirteen patients (37%) had a single lesion at diagnosis, and the mean number of lesions was 3.37. Twenty-three patients (65.71%) had diabetes mellitus (type 1 in 10 cases and type 2 in 13). In 20 patients, onset of diabetes preceded that of NL by a mean of 135.70 months. The 2 conditions were diagnosed simultaneously in 3 patients. None of the 35 patients developed diabetes mellitus during follow-up. Six patients had hypothyroidism, and 4 of these also had type 1 diabetes. NL is frequently associated with type 1 and 2 diabetes. Although diabetes tends to develop before NL, it can occur simultaneously. Copyright © 2014 Elsevier España, S.L.U. and AEDV. All rights reserved.

    Jeune syndrome (JS, also described as asphyxiating thoracic dystrophy, ATD) is a rare autosomal recessive skeletal dysplasia characterized by a small, narrow chest and variable limb shortness with a considerable neonatal mortality as a result of respiratory distress. Significant life-threatening cervical spine abnormalities can be typical. Here we describe the case of a male infant of Sardinian origin, who developed respiratory distress and feeding difficulties from the first months, correlated with muscle\\skeletal dysmorphism prevalent on chest. Nocturnal respiratory sleep alterations were reported from parents. After clinical, genetics, radiographic and cervical MRI investigations, ATD diagnosis with C1 stenosis. A full-night video-polysomnographic study was performed in order to evaluate the sleep apnea condition. The study showed a condition of tachipnea\\tachicardia, with several short respiratory events during sleep, both obstructive and central type with apneahypopnea index (AHI) 17/ h, mean duration 3.7 sec with longest 20 sec. It can be hypothesized that the combination of altered respiratory and cardiac frequency is related to central type of sleep respiratory disorders consequent to C1 compression, while the obstructive minor component is related to thoracic restrictive disorders. Full night lab-polygraphy is recommended in dysmorphic skeletal disorders like JS.

    To support more rigorous analysis on global security issues at Sandia National Laboratories (SNL), there is a need to develop realistic data sets without using "real" data or identifying "real" vulnerabilities, hazards or geopolitically embarrassing shortcomings. In response, an interdisciplinary team led by subject matter experts in SNL's Center for Global Security and Cooperation (CGSC) developed a hypothetical case description. This hypothetical case description assigns various attributes related to international SNF transportation that are representative, illustrative and indicative of "real" characteristics of "real" countries. There is no intent to identify any particular country and any similarity with specific real-world events is purely coincidental. To support the goal of this report to provide a case description (and set of scenarios of concern) for international SNF transportation inclusive of as much "real-world" complexity as possible -- without crossing over into politically sensitive or classified information -- this SAND report provides a subject matter expert-validated (and detailed) description of both technical and political influences on the international transportation of spent nuclear fuel.

  6. Lagrangian Description for Particle Interpretations of Quantum Mechanics: Entangled Many-Particle Case

    Science.gov (United States)

    Sutherland, Roderick I.

    2017-02-01

    A Lagrangian formulation is constructed for particle interpretations of quantum mechanics, a well-known example of such an interpretation being the Bohm model. The advantages of such a description are that the equations for particle motion, field evolution and conservation laws can all be deduced from a single Lagrangian density expression. The formalism presented is Lorentz invariant. This paper follows on from a previous one which was limited to the single-particle case. The present paper treats the more general case of many particles in an entangled state. It is found that describing more than one particle while maintaining a relativistic description requires the specification of final boundary conditions as well as the usual initial ones, with the experimenter's controllable choice of the final conditions thereby exerting a backwards-in-time influence. This retrocausality then allows an important theoretical step forward to be made, namely that it becomes possible to dispense with the usual, many-dimensional description in configuration space and instead revert to a description in space-time using separate, single-particle wavefunctions.

    2016-12-01

    Malignant mesothelioma is an uncommon neoplasm that develops from serous surfaces, and rarely from the tunica vaginalis. Although atypical in any location, paratesticular presentation is exceedingly infrequent as only 0.3% to 1.4% of mesothelioma cases arise from the tunica vaginalis. Fewer than 300 cases have been reported with very few descriptions of long term follow up and multimodal therapy. Here we describe a patient with 2 years of follow up for metastatic mesothelioma treated with orchiectomy, chemotherapy and robot-assisted laparoscopic retroperitoneal lymph node dissection.

    Full Text Available The present papers offers a case study of a Japanese loanword verb, with the aim of contributing to corpus-based research on Japanese loanwords and of providing a foundation for the compilation of a dictionary of grammatical patterns of loanwords for learners of Japanese as a foreign language. The case study presents an analysis of actual usage of loanword suru-verbs in the large-scale Balanced Corpus of Contemporary Written Japanese, which is followed by a detailed analysis of all examples of the polysemous verb katto-suru. It is thereby shown how corpora can help in describing loanwords by matching a word’s meaning with its patterns of usage, and how such a description can be useful to learners of Japanese as a foreign language.

    Recent research has challenged classic theories of hippocampal function in spatial memory with findings that the hippocampus may be necessary for detailed representations of environments learned long ago, but not for remembering the gist or schematic aspects that are sufficient for navigating within those environments (Rosenbaum et al., 2000; Rosenbaum, Winocur, Binns, & Moscovitch, 2012). We aimed to probe further distinctions between detailed and schematic representations of familiar environments in three cases of hippocampal/medial temporal lobe (MTL) amnesia by testing them on a route description task and mental navigation tasks that assess the identity and location of landmarks, and distances and directions between them. The amnesic cases could describe basic directions along known, imagined routes, estimate distance and direction between well-known landmarks, and produce sketch maps with accurate layouts, suggestive of intact schematic representations. However, findings that their route descriptions lack richness of detail, along with impoverished sketch maps and poor landmark recognition, substantiates previous findings that detailed representations are hippocampus-dependent.

    1994-12-31

    Budget cuts and increasing demands for a technically competent work force are problems facing industry and government today. Training requirements must be met in a cost-effective manner. The videoconference format is a proven method that saves money on training and travel costs. However, designing a training series that meets the needs of a diverse audience composed of scientists, engineers, and management from government, industry and universities is extremely challenging. National Environmental Technology Network (NETWORK), a department of University of New Mexico`s College of Engineering, has a proven track record in developing and producing effective videoconference training programs for industry, government, national laboratories, and universities. To data, six successful series have been completed: Total Quality Management (two series, one for service organizations and one for manufacturing); Hazardous Waste Management; Waste Minimization and Pollution Prevention; Environmental Risk Management; and Radioactive Waste Management. National awards from the United States Distance Learning and the United States Environmental Protection Agency attest to NETWORK`s leadership in providing advanced technical training using distance learning techniques. This presentation describes how to produce an environmental television series and reveals the keys to successful videoconferencing by describing the past successes of NETWORK`s videoconference training and the plans for the up-coming series, Mixed Waste Management. The presentation characterizes how videoconferences can be used as university-developed advanced technical training for shifting the work force from defense projects to environmental remediation and protection. The presentation illustrates how the effectiveness of this training is enhanced by partnerships which evolve between the originating university and the receiving sites.

    Hong, Choon Chiet; Liu, Ka Po Gabriel

    2015-02-01

    Study Design Case report and literature review. Objective Multiregional spinal stenosis (MRSS) has not been described in the English literature, although a few studies report the concept of tandem spinal stenosis. Due to the concurrent spinal stenosis occurring in three separate regions of the spine, clinical presentation of MRSS may be less distinct, and its surgical treatment priorities and challenges differ from single-region spinal stenosis. The purpose of this article is to describe a new concept and a rare case of MRSS as separated segments of spinal stenosis in the cervical, thoracic, and lumbar spine. Methods A retrospective case description of MRSS and surgical strategies used in managing such extensive multiregional stenosis and its potential complications. Results  A novel surgical strategy using a combination of laminectomies with fusion and laminoplasty without fusion to treat this patient with such extensive cervical to thoracic myelopathic cord compression is described. Initial good recovery after cervical cord decompression was followed by a delayed recurrence of symptoms from thoracic cord compression. The subsequent thoracic surgical decompression, its complications and management, and patient recovery are discussed with a literature review highlighting the possible mechanisms for postoperative loss of neurologic function after thoracic decompression. Conclusion MRSS is a rare cause of extensive compression of multiple regions of the spinal cord. To the best of the authors' knowledge, this report is the first to use the term multiregional spinal stenosis to describe this new emergent clinical entity, surgical management strategies, and potential complications.

    The article describes two clinical cases of severe primary hyperparathyroidism (PHPT) caused by parathyroid carcinoma in young female patients who underwent molecular genetic testing to rule out the hereditary forms of PHPT. In both patients, heterozygous germline nonsense mutations of tumor suppressor gene CDC73 encoding parafibromin (p.R91X and p.Q166X) were identified using next-generation sequencing with Ion Torrent Personal Genome Machine (Thermo Fisher Scientific - Life Technologies, USA). It is the first description of CDC73 mutations in Russia, one of the mutations is described for the first time in the world. Identification of germline mutations in the CDC73 gene in patients with PHPT necessitates regular lifelong screening for other manifestations of hyperparathyroidism-jaw tumor syndrome (HPT-JT), PHPT recurrence due to parathyroid carcinoma as well, and identification of mutation carriers among first-degree relatives.

    Fery, Patrick; Morais, Jose

    2003-10-01

    We report a new case of visual associative agnosia. Our patient (DJ) was impaired in several tasks assessing visual processing of real objects, colour pictures, and line drawings. The deficit was present both with naming and gesturing responses. Object processing in other modalities (verbal, auditory nonverbal, and tactile) was intact. Semantic processing was impaired in the visual but not in the verbal modality. Picture-word matching was better than single picture identification. DJ's visual perceptual processing, was intact in several tasks such as visual attributes discrimination, shape discrimination, illusory contours perception, segmentation, embedded figures processing and matching objects under different viewpoints. Most importantly, we show that there was no impairment of stored structural descriptions and that the patient was able to build new visual representations. These results are considered in the context of Farah's (1990, 1991) proposals about visual associative agnosia.

  17. Bridging molecular and continuous descriptions: the case of dynamics in clays

    Directory of Open Access Journals (Sweden)

    Jean-François Dufrêche

    2010-03-01

    Full Text Available The theory of transport in porous media such as clays depends on the level of description. On the macroscopic scale,hydrodynamics equations are used. These continuous descriptions are convenient to model the fluid motion in a confined system. Nevertheless, they are valid only if the pores of the material are much larger than the molecular size of the components of the system. Another approach consists in using molecular descriptions. These two methods which correspond to different levels of description are complementary. The link between them can be clarified by using a coarse-graining procedure where the microscopic laws are averaged over fast variables to get the long time macroscopic laws. We present such an approach in the case of clays. Firstly, we detail the various levels of description and the relations among them, by emphasizing the validity domain of the hydrodynamic equations. Secondly, we focus on the case of dehydrated clays where hydrodynamics is not relevant. We show that it is possible to derive a simple model for the motion of the cesium ion based on the difference on time scale between the solvent and the solute particles.A teoria de transporte em meios porosos tais como argilasdepende do nível de descrição. Na escala macroscópica, equações da hidrodinâmica são utilizadas. Tais descrições a níveldo contínuo são convenientes para tratar o movimento do fluido em sistemas confinados. No entanto, tais equações são válidas se os poros do material são muito maiores do que as moléculas das componentes do sistema. Uma outra abordagem consiste em usar descrições moleculares. Esses dois métodos que correspondem a diferentes níveis de descriçãosão complementares. A ligação entre eles pode ser elucidada usando um procedimento de mudança de escala onde são tomadas médias das leis microscópicas sobre as variáveis rápidas para se obter as leis macroscópicas para tempos longos.

    Suarez, Michelle Ann

    2015-06-01

    Food selectivity is common in children with and without developmental disabilities and can have negative implications for nutrition intake and family quality of life. The evidence base for effective treatment protocols is still developing. The purpose of this study was to describe a pilot, multicomponent treatment protocol for food selectivity and present several case examples using a retrospective chart review. Elements in the treatment manual included sensory integration and behavioral modification strategies, including systematic desensitization. Also, parents were educated on factors associated with food selectivity and strategies for increasing food acceptance during family meals. Four children with food selectivity demonstrated increased food acceptance of previously refused foods. Incidence of negative behaviors, including gagging, vomiting, and aggressive behavior (eg, hitting, batting away spoon), during clinical meals was also evaluated. No aggressive behavior or vomiting was observed during treatment sessions, and gagging on foods at initial introduction was minimal. This descriptive study and case review provides information to inform treatment of food selectivity and may provide a catalyst for larger scale clinical trials. © 2014 American Society for Parenteral and Enteral Nutrition.

    Hemoglobinopathies are congenital disorders resultimg from hemoglobin abnormalities. Major forms are often severe, their management is difficult and associated with a great psychosocial impact on patients and their families. They are classified as rare diseases and are still insufficiently known by health professionals. This lack of knowledge is at the origin of diagnostic errors, delay in their management and therefore high morbidity and mortality rate for these patients. In 2008, the World Health Organization (WHO) has published data on hemoglobinopathies epidemiology: more than 330.000 cases of hemoglobinopathy occur each year (83% of cases of sickle cell anemia, 17 % of cases of thalassemia). Hemoglobin disorders are responsible for approximately 3.4% of deaths among people under the age of 5. At the global level, approximately 7% of pregnant women would be carriers of a form of thalassemia and 1% of couples are at risk. However, they are relatively frequent in some regions of the globe where consanguineous marriages are common. We conducted a descriptive cross-sectional study based on two surveys, the first in May 2015 and the second in June of the same year. It was performed in the immunization days to deliver pneumococcal vaccine to the index cases and it was aimed to describe the epidemiological features of families at risk of hemoglobinopathies (index case study), whose index cases were treated in the Department of Pediatrics at the Provincial Hospital El Idrisi, Kenitra, Morocco. After having collected the epidemiological data from patients, laboratory tests were performed including: blood count with red blood cells morphological assessment using the MGG assay and automatic numbering of reticulocytes; hemoglobin electrophoresis at alkaline pH (8.8) and then at acid pH (5.4) on agarose gel and densitometric integration. 275 patients had laboratory profiles compatible with hemoglobinopathy. The majority of these patients were born to consanguineous

    Withdrawal pain can be a barrier to opioid cessation. Yet, little is known about old injury site pain in this context. We conducted an exploratory mixed-methods descriptive case series using a web-based survey and in-person interviews with adults recruited from pain and addiction treatment and research settings. We included individuals who self-reported a past significant injury that was healed and pain-free before the initiation of opioids, which then became temporarily painful upon opioid cessation-a phenomenon we have named withdrawal-associated injury site pain (WISP). Screening identified WISP in 47 people, of whom 34 (72%) completed the descriptive survey, including 21 who completed qualitative interviews. Recalled pain severity scores for WISP were typically high (median: 8/10; interquartile range [IQR]: 2), emotionally and physically aversive, and took approximately 2 weeks to resolve (median: 14; IQR: 24 days). Withdrawal-associated injury site pain intensity was typically slightly less than participants' original injury pain (median: 10/10; IQR: 3), and more painful than other generalized withdrawal symptoms which also lasted approximately 2 weeks (median: 13; IQR: 25 days). Fifteen surveyed participants (44%) reported returning to opioid use because of WISP in the past. Participants developed theories about the etiology of WISP, including that the pain is the brain's way of communicating a desire for opioids. This research represents the first known documentation that previously healed, and pain-free injury sites can temporarily become painful again during opioid withdrawal, an experience which may be a barrier to opioid cessation, and a contributor to opioid reinitiation.

    Two cases of a previously undescribed cervical spinal anomaly distinct from cervical spondylolysis are presented. The authors report the first detailed description of a congenital vertebral anomaly characterized by multilevel cervical spondylolysis, sagittal deformity, and spinal cord compression. The sine qua non of the condition is a lack of communication between the anterior and posterior columns of the cervical spinal canal, which may occur over several vertebral levels. A kyphotic deformity of the anterior column occurs, whereas the posterior column may have relatively normal alignment. The underlying biomechanical stresses caused by the anterior-posterior column disconnection result in spinal instability and progressive kyphotic deformity, often to a profound degree. Two children, 2 and 3 years of age, presented with congenital multilevel disconnection and myelopathy. In the first stage of treatment, each underwent an anterior decompression, reduction, and reconstruction of the involved segments. This was followed by posterior stabilization and fusion as a separate procedure. In both patients, the myelopathy improved and a solid, circumferential fusion was achieved. The authors' success in treating these patients indicates that management of these conditions can be based on the principles of deformity correction, spinal cord decompression, and combined anterior-posterior arthrodesis.

    To examine the results of the multimodal management of patients with endangering hepatic hemangioma associated with systemic compromise. Retrospective descriptive case series of children with endangering hepatic hemangioma managed at our institution between January 1996 and June 2006. Six children (5 females) presented with endangering hepatic hemangioma with systemic effects during the index time period. Mean age at presentation was 1.9 months (range, 2 days to 4 months). All patients received medical treatment, and all patients also underwent hepatic embolization, with a median number of procedures of 2 (range, 1-6). Two patients died, one of sepsis and one of progressive liver failure in a child presenting with advanced liver disease owing to neonatal hemochromatosis that was unrecognized at the time. The remaining 4 patients all recovered and were discharged. With mean postprocedure follow-up of 2.11 years (range, 0-6.2 years), all remain well. Multimodal management of endangering hepatic hemangioma is a strategy that deserves consideration in the management of these patients. Although the strategy requires further evaluation as to its safety and efficacy, the procedure has the potential to decrease the need for liver transplantation because of treatment failures in this population.

    Systemic lupus erythematosus is a non-specific inflammatory disorder of an organ of unknown cause and autoimmune origin. Visceral injuries, including those cardiovascular, determine the prognosis of this disease primarily affecting women. The objectives of this study were to determine the frequency and describe the cardiovascular manifestations in systemic lupus erythematosus in a lupus population of the Dakar region. This is a multicenter prospective study descriptive and analytical conducted in the region of Dakar (Senegal) from 14 February 2011 to 2 July 2012. Patients were either hospitalized or monitored as outpatients. Included were all patients with lupus and meeting at least four criteria of the American College of Rheumatology of lupus disease classification 1997. All patients underwent physical examination, an electrocardiogram and an echocardiogram looking for cardiovascular damage. The collected data were entered into the Epi Info version 3.5.1 and processed with SPSS 16.0 software. Quantitative variables are described in the median and the qualitative workforce, percentage and frequency. We have included 50 patients. The average age of the population was 36.18 years. A female predominance is noted with a sex ratio man/woman of 0.09. Cardiovascular functional symptoms were dominated by dyspnea stage II to IV NYHA (26%) and palpitations (22%). The physical signs we have found were mainly tachycardia (40%), spontaneous turgor of the jugular veins (29%), a muffling of the heart sounds (29%) and a infandibulopulmonairy shock (18%). The frequency of cardiovascular events was 46%. Electrical cardiac events were dominated by sinus tachycardia (40%) of repolarization disorders (16.3%) type of ischemia, injury, ischemia injury, necrosis and hypertrophy with 18% atrial and left ventricular hypertrophy each. Furthermore, one case of BAV first degree at 280 ms was recorded. We found 19 cases of pericarditis including 2 tamponade, 3 cases of dilated cardiomyopathy

    Previous efforts to produce case descriptions have typically not focused on the organizations that produce research evidence and support its use. External evaluations of such organizations have typically not been analyzed as a group to identify the lessons that have emerged across multiple evaluations. Case descriptions offer the potential for capturing the views and experiences of many individuals who are familiar with an organization, including staff, advocates, and critics. We purposively sampled a subgroup of organizations from among those that participated in the second (interview) phase of the study and (once) from among other organizations with which we were familiar. We developed and pilot-tested a case description data collection protocol, and conducted site visits that included both interviews and documentary analyses. Themes were identified from among responses to semi-structured questions using a constant comparative method of analysis. We produced both a brief (one to two pages) written description and a video documentary for each case. We conducted 51 interviews as part of the eight site visits. Two organizational strengths were repeatedly cited by individuals participating in the site visits: use of an evidence-based approach (which was identified as being very time-consuming) and existence of a strong relationship between researchers and policymakers (which can be challenged by conflicts of interest). Two organizational weaknesses - a lack of resources and the presence of conflicts of interest - were repeatedly cited by individuals participating in the site visits. Participants offered two main suggestions for the World Health Organization (and other international organizations and networks): 1) mobilize one or more of government support, financial resources, and the participation of both policymakers and researchers; and 2) create knowledge-related global public goods.

    Myeloid sarcoma (MS) is a rare malignant solid tumor presented with myeloid blast cells showing varying degrees of maturation. MS may have an extramedullary site, precede, or develop simultaneously with the clinical manifestations of acute myeloid leukemia (AML); it may also occur as an AML relapse. Besides AML, MS may be a manifestation of chronic myeloid leukemia or other chronic myeloproliferative diseases. Due to the fact that this disease is rare, the bulk of the literature on MS is presented with single descriptions of retrospective studies and clinical cases. The paper describes 3 cases of MS with inversion of chromosome 16 and small bowel lesion.

    The Solomon Islands has one of the highest rates of domestic violence in the world. This paper is a descriptive case series of all cases of domestic violence presenting to the Solomon Islands National Referral Hospital (NRH) over 18 years. Data were routinely collected from a database of all patients who were treated by NRH general surgery and orthopedic clinicians between 1994 and 2011, inclusive. The total number of cases in the injury database as a result of domestic violence was 387. The average number of cases in the database per year from 1994 to 2011 was 20. There were 6% more female patients (205 of 387; 53%) than male (182 of 387; 47%). Of the cases in which the perpetrator of the violence against a female patient was specified (111 of 205 female cases), 74% (82 of 111) were the patient's husband. Only 5% (5 of 111) of cases in females were inflicted by another female. This analysis provides the best available information on domestic violence cases requiring a visit to a tertiary hospital in a Pacific Island in the specified time period and is undoubtedly an under-estimate of the total cases of domestic violence. Preventing and treating domestic violence in the Solomon Islands and in the Pacific is an important challenge and there is a significant role for secondary and tertiary health services in screening for and preventing domestic violence.

    In cases of neonaticide with delayed finding of the body, interpretation of autopsy results can be difficult because of decomposition. Postmortem computed tomography (PMCT) has become an increasingly popular tool in the (pediatric) forensic field. We performed a retrospective study to compare the outcome of PMCT with autopsy results in suspected neonaticide, in neonates found more than one week after their demise. We compared the performance of both methods on (1) determining gestational age, (2) differentiating between live birth and still birth and (3) determining cause of death. We selected all consecutive neonaticide cases with an estimated postmortem interval longer than one week, who underwent a forensic autopsy including a total body PMCT in the Netherlands Forensic Institute in the period 2008-2012. Both a pathologist and radiologist scored gestational age, signs of live birth and cause of death for each case. 22 cases of neonaticide were identified in the study period, of which 15 cases were estimated to be found more than 1 week after death. In 12 of these a total body PMCT was performed. In all cases, late postmortem changes were present. Gestational age could be assessed with PMCT in 100% of the cases and with autopsy in 58% of the cases. In all cases neither PMCT nor autopsy was able to assess live birth and cause of death. PMCT is a better tool for estimating gestational age in case of suspected neonaticide with late postmortem changes compared to autopsy and should therefore be a standard part of the work-up. Signs of live birth and cause of death could not be determined with neither of the methods, an adjusted post mortem examination including limited autopsy for these cases might be developed.

    A variety of approaches are available that provide cultural competency education for practicing physicians. There is, however, still a need for additional, innovative approaches that address continuing education and professional improvement regarding cultural competency for physicians after their training. To assess the potential impact on established clinicians of writing an extended case narrative on cultural competency. We conducted structured interviews of physician contributors (n = 14) to a book of cases on cultural competency. Authors were invited to contribute to the book based on their experiences as established clinicians, and previous expertise in cultural competency research or education was not required. Because of this, the editors employed a process in which they worked with contributors in a one-on-one manner to develop their case(s). The participants were experienced physicians (all > 10 years since medical school graduation), most of whom were white (64%) and affiliated with an academic medical center (86%). The majority of the contributors (1) reported that writing their case(s) increased their awareness of, and sensitivity to, issues of cultural competency; (2) indicated that the writing of their case(s) changed their approach to patient care and/ or their education of medical students or graduate medical trainees; and (3) would recommend case writing as a vehicle for promoting cultural sensitivity and awareness. Although preliminary, these data suggest that the cultural awareness, sensitivity, and competence of established physicians might be enhanced by a process in which clinicians are facilitated in the writing of cases that address issues of culture that are pertinent to their practice and patient experiences.

    Full Text Available Thymic Hyperplasia is an extremely rare neoplasm of thymus which is localized in the anterior mediastinum. Generally it occurs secondary to the different diseases. Some of them occurs idiopathicly. Until today there are more than 50 cases reported and most of them are children between the ages of 1 and 17. A few cases are adults. But until today there is no reported case with the same brothers and sisters. Therefore we want to point on whether thymic hyperplasia can be hereditary or not.

Gestational trophoblastic neoplasia (GTN, is recognized as the most curable gynecologic malignancy. However, many cases are resistant to first line chemotherapy. We present cases of invasive mole. They were diagnosed as a vesicular mole on ultrasonography and underwent suction and evacuation but vaginal bleeding recurred with plateau and rising B-hcg with intramyometrial vascular lesion. Hysterectomy was done that indicated invasive mole. Patients were cured of their symptoms. Surgical therapy (hysterectomy with chemotherapy has shown to achieve remission in these cases especially with resistance to chemotherapy and in perimenopause.

    A case of atlas assimilation revealed during serial study of suboccipital region is presented. The specimen was harvested from the body of 31-year-old woman. Images of the computed tomography scans are correlated with classic dissection. Asymmetrical bony assimilation is accompanied by asymmetrical development of the suboccipital musculature. In the presented case, the atlantic segments of both vertebral arteries preserved their usual course between bony elements derived from the atlas and proatlas. Development of the soft tissues must be influenced by similar factors as development of the skeleton. Detailed radiologic studies, possibly with volumetric reconstructions, are necessary in cases of atlas assimilation before surgical interventions in the region of craniovertebral junction.

    Full Text Available The Organisational Climate Description Questionnaire - Rutgers Elementary (OCDQ - RE was used to determine the current organizational climate of primary schools in North-West Province, South Africa. This questionnaire evaluates the actions of principals and educators; the current organizational climate in primary schools can be determined from the results. A quantitative research approach, with 904 teachers from 68 schools, was used to determine the applicability of the measuring instrument. Exploratory and confirmatory factor analyses revealed that certain items measuring directive behaviour in the OCDQ-RE grouped with supportive behaviour of the principal. Hence, in this study, these items were regarded as supportive towards the educators and their work by the respondents. According to Cronbach's alpha coefficient the questionnaire can be regarded as reliable. Recommendations are made to render the questionnaire even more applicable for the South African context.

    Full Text Available Only a few cases of pneumocystis pneumonia (PCP in Cushing’s syndrome have been published in the literature so far. In the majority of these patients, the pneumonia occurred after reduction of the hypercortisolism with medicamentous treatment. We report two cases of PCP during conservative treatment of hypercortisolism. We describe clinical, imaging and laboratory findings in two patients and review published cases of pneumocystits pneumonia in Cushing’s syndrome. A 60-year-old woman and 20-year-old man with Cushing’s syndrome due to ectopic ACTH syndrome were treated at our department. Both developed pneumocystis pneumonia early after treatment with ketoconazole and ethomidate bromide had been introduced and the levels of cortisol rapidly decreased. PCP prophylaxis in patients with high cortisolemia should be started before treatment of hypercortisolism in current practice. Gradual lowering of plasma cortisol should also reduce the risk of infection by Pneumocystis jiroveci.

This diagnosis was made based on characteristic ultrasonography findings in a patient that was undergoing routine surveillance for a suspected clinical diagnosis of Beckwith-Wiedemann syndrome. The patient remains asymptomatic and currently no surgical interventions have been needed. We review the pathophysiology and ultrasonographic findings of this rare condition and present a comparison with the only other four pediatric cases of adenomyomatosis of the gallbladder.

    Full Text Available With the objective of reporting the technique of ultrasound-guided hydrostatic reduction of intestinal intussusception, three cases with confirmed diagnosis of the disease submitted to reduction with this technique are described. All cases had successful reductions with no complications. One patient experienced a recurrence of the invagination eight days after treatment, which was surgically corrected. The technique of hydrostatic reversal of intestinal intussusception guided by ultrasound may be used in place of the conventional barium enema, since it is a minimally invasive and safe method, with high rates of success and few complications.

    Full Text Available Xanthogranulomatous pyelonephritis is a rare and peculiar form of chronic pyelonephritis and is generally associated with renal lithiasis. Its incidence is higher in females. The peculiarity of this disease is that it requires a differential diagnosis, because it can often simulate dramatic pathologic conditions. In fact, in the literature are also described cases in association with squamous cell carcinoma of the kidney The radiologic clinical findings simulate renal masses, sometimes in association with caval thrombus. We describe a case of xanthogranulomatous pyelonephritis with radiologic aspects of a complex cyst of Bosniak class III in a man 40-year old.

    Pituitary apoplexy is usually the result of hemorrhagic infarction in a pituitary adenoma. The clinical presentation varies widely and includes asymptomatic cases, classical pituitary apoplexy and even sudden death. Cerebral ischemia due to pituitary apoplexy is very rare. It may be caused by vasospasm or direct compression of cerebral vessels by the tumor. We report a case of pituitary apoplexy associated with cerebral infarction and discuss the relationship between the two events. Copyright © 2016 Sociedad Española de Neurocirugía.

    2008-01-01

    Full Text Available Soft tissue sarcomas are rare tumours with infrequent identified aetiological factors. Several genetic syndromes as well as previous radiation therapy and/or chronic lymphoedema have been suspected to predispose to some soft tissue sarcomas. Between January 1997 and September 2005, we carried out a prospective descriptive study to estimate the frequency of some particular etiological factors among 658 patients with soft tissue sarcomas. Sarcomas associated with a clinically identified genetic disease represent 2.8% out of all cases (95%CI: 1.5–3.8%. Most of these cases (14/19 are related to Recklinghausen neurofibromatosis. Radiation-induced sarcomas represent 3.3% out of all cases (95%CI: 1.7–5.1%. Most of these cases (9/22 are related to prior breast cancer treatment. We had observed only 1 case of Stewart-Treves syndrome. Liposarcoma, the most frequent histological subtype observed, is not associated with any particular aetiological entity. Finally, most of the adult soft tissue sarcomas are not related to any classical clinically identified genetic disease or previous radiation therapy and/or chronic lymphoedema risk factors. Frequency of underlying genetic syndrome which may predispose to soft tissue sarcomas could be higher than previously reported.

    Full Text Available Introduction Measles is a vaccine preventable viral disease that affects mostly children under-five years of age. It is highly contagious infection associated with high morbidity and mortality. Objective To describe the morbidity and mortality pattern of measles cases in person, place and time. Methods A health facility based study and cross sectional descriptive study design was used. All cases of measles that presented at the facility from January to June 2016 were profiled and their medical records reviewed. Representative blood samples were taken and analyzed using the Enzyme linked immunosorbent assay (ELISA method for the diagnosis of measles. Data was entered into MS Excel version 2016 and later analysed using Epi-info version 7. Results A total of 149 patients were seen over a period of 6 months. They represent 88 males and 61 females with a male to female ratio of 2:1. The median age of the cases was 30 months (range of 108 months to 9 month. The trend analysis shows a steady increased in number of cases from January with the month of March having the highest number of 46 cases, then there was steady decline for the subsequent months. Only 14 children, which accounted for 9.4% were reported to have being vaccinated against measles, while majority, 135 that represented 90.6% were not. Seven deaths were recorded; all were males and among cases that never received vaccine against measles, giving Case fatality rate (CFR of 5.0%. Measles specific immunoglobulin M (IgM was detected in all the blood samples that were sent for investigations. Conclusion Nearly all the cases did not receive measles vaccine and among the deaths recorded, none had been vaccinated against measles. Concerted efforts are required by all stakeholders to ensure every child is completely immunized in line with the global measles elimination strategy.

    In an attempt to reduce iatrogenic ureteral injury, urologists are frequently called on for placement of prophylactic ureteral catheters in difficult pelvic surgeries. Reflux anuria, which may be more appropriately termed catheter-induced obstructive anuria, has been reported as a complication of ureteral catheter placement and is characterized by the absence of urine output after ureteral manipulation because of edema and obstruction. We report a case of obstructive anuria after bilateral ureteral catheter removal and review the literature regarding this rare complication. Medline was searched for all relevant case reports, case series, and trials that included prophylactic ureteral catheters and described complications of their use. Published series report varying incidence of obstructive anuria after prophylactic ureteral catheter removal from 0% to 7.6%. There are no proven strategies for prevention of obstructive anuria after prophylactic ureteral catheter removal, but staged removal has shown a trend toward reduced incidence. When encountered, most cases of anuria after catheter removal resolved with medical management alone; however, indwelling stent placement has been advocated while ureteral edema resolves.

    Uterine neoplasms of epithelial origin are rare in cats and most often are described in older females. Yet, in less than 2 years, four ovariohysterectomy specimens were submitted from different practices to the Laboratory of Histology and Anatomical Pathology, at UTAD (Vila Real, Portugal), that emitted a diagnosis of feline endometrial adenocarcinoma. Untypically, all the females were aged <1 year old at the surgery. Access to the clinical files was requested to document the clinical features of the four cases, including any complementary data available, to construct the present case reports. The clinical situation developed with discrete signs, but vulvar discharge was present in three cases, ranging from bloody to brownish or colourless, and from purulent to mucous. The females were in dioestrus, although the oestrus remained unperceived in most cases. In this study, the four clinical situations are described and discussed on the basis of available literature, highlighting the aspects that may impair an early diagnosis and that may favour the progression of the disease and also that age should not be an excluding criteria when analysing the differential diagnosis list. © 2013 Blackwell Verlag GmbH.

    Nasal cavities foreign bodies are common accidents in children, sometimes leading, in accordance with the literature, to complications such as epistaxis and bronchoaspiration. Diagnosis is often made with anterior rhinoscopy, but sometimes nasal fibroendoscopy and imaging may be useful. To evaluate 420 cases of nasal foreign bodies removed in ENT Service of Souza Aguiar Hospital, Rio de Janeiro, as related to sex, age, type of foreign body and complications. 420 cases of nasal foreign bodies removed in the ENT service of Souza Aguiar Hospital between December 1992 and December 1998 were evaluated according to the parameters related above. We found higher incidence between 0 and 4 years of age, and the most frequently found foreign bodies were foam fragments, plastic pieces of little toys, beans and paper fragments. Complications occurred in 9.05% of the cases, epistaxis and vestibulitis being the commonest. Nasal foreign bodies are especially found between the ages of 0 and 4 years. In our study, foam fragments and small plastic objects were the most frequent foreign bodies found. Complications were found in 9.05% of the cases, headed by epistaxis and nasal vestibulitis.

    Malaria causes around 863,000 deaths per year, mostly of them in children under 5 years old. We have reviewed the epidemiological data of malaria cases in a pediatric department in a Hospital in the Community of Madrid, in the period 1996-2011. In the period reviewed, 103 cases of malaria were diagnosed in children under 14 years old. Sixty percent were males and the average age was 4.5 years. In most cases, the infection arose during a visit to relatives in the country of origin. The vast majority did not have malaria prophylaxis. Twenty-five percent of the cases were diagnosed as complicated malaria, the main criteria being hyperparasitemia, of which 80% of the patients did not present any other complications A high level of suspicion must be maintained in any patient who comes from a malaria endemic area. The key factor responsible for the infection was the lack of chemoprophylaxis. Copyright © 2013 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.

    To determine the clinical characteristics and outcome of patients with chronic hepatitis C virus (HCV) infection presenting severe autoimmune cytopenia unrelated to interferon alpha therapy, we analyzed characteristics and outcomes of 35 patients with HCV (16 from our departments and 19 from the literature). We considered active autoimmune hemolytic anemia (AHA) as a decrease of at least 2 g/dL in hemoglobin levels, an increase of at least 0.6 mg/dL in the serum unconjugated bilirubin level, a reticulocyte count >5%, and a positive direct Coombs test. Severe neutropenia was defined as a neutrophil count cases), severe thrombocytopenia (16 cases), aplastic anemia (2 cases), severe neutropenia (1 case), refractory sideroblastic anemia (1 case), and pure red cell aplasia (1 case). Three patients simultaneously presented 2 types of severe cytopenias. Twenty-seven patients (77%) were female and 8 (23%) male, with a mean age at diagnosis of cytopenia of 51.7 years (range, 18-84 yr). Immunologic markers were detected in 19 (68%) of 28 patients, the most frequent being hypocomplementemia in 16 (57%), cryoglobulins in 15 (54%), antinuclear antibodies in 12 (43%), and rheumatoid factor in 5 (18%). Other associated processes were autoimmune diseases in 14 (50%) of 28 and human immunodeficiency virus (HIV) coinfection in 3 (9%) of 32. We found clinical and immunologic differences between HCV patients with AHA and those with severe thrombocytopenia. Patients with HCV-related AHA showed a higher prevalence of associated autoimmune diseases (71%), cryoglobulins (67%), and cirrhosis (59%). All had a good response to corticosteroids, but a poor prognosis (47% mortality). In contrast, patients with HCV-related severe thrombocytopenia had a lower prevalence of associated autoimmune diseases (11%), a poorer response to corticosteroids (55%), and lower mortality (6%), with HIV/HBV coinfections in some patients. The 35 cases presented demonstrate that different types of immune

    Impaired memory, and more particularly spatial orientation, occurs in pathologies such as dementia, cerebrovascular accidents or traumatic brain injuries. Less frequently it also appears as a transient disorder in healthy people with no apparent brain damage, in which case it is known as transient topographical amnesia (TTA). The aim of this work is to report on a series of eight cases of TTA that were evaluated in a neurology unit. We study the cases of eight patients diagnosed with TTA over the period 2002-2008. Patients were considered to fulfil eligibility criteria if they had presented at least one episode of spatial disorientation, with no loss of memory or consciousness, and were able to describe the events that had taken place, without any previous cognitive impairment and with a normal neurological examination. The demographic characteristics taken into account in the study were: predominance of females (75%) and a mean age of 69.13 +/- 8.79 years. The mean number of episodes was 1.75 (range: 1-3), which lasted an average of 24.5 minutes. Three of the eight patients had associated vascular risk factors. Neuroimaging studies did not reveal any relevant findings in any of the eight patients, except one case of a bilateral frontal porencephalic area resulting from a traumatic brain injury suffered in the past. Simple single-photon emission tomography and Doppler ultrasound imaging scans of the brain, as well as an electroencephalogram, were performed on two patients, the results being normal in all cases. Follow-ups were performed on all the patients, without any kind clinical change being observed, except for one patient who developed dementia at six years after the episode of amnesia. TTA is possibly an underdiagnosed condition which we believe should be included in the differential diagnosis of patients who are referred owing to suspected cognitive impairment.

    Highlights: • Characteristics of Ag-supported MgO(100) films are studied with different DFT functionals. • All approaches predict a similar nature of supported pristine and oxygen-deficient films. • Interface distances and adhesion are particularly sensitive to the choice of the approximation. • Satisfactory matching with the experiment is obtained with the DFT-optB88 functional. • Charge transfer, work function and vacancy characteristics are little influenced by the method. - Abstract: We compare the performances of different DFT functionals applied to ultra-thin MgO(100) films supported on the Ag(100) surface, a prototypical system of a weakly interacting oxide/metal interface, extensively studied in the past. Beyond semi-local DFT-GGA approximation, we also use the hybrid DFT-HSE approach to improve the description of the oxide electronic structure. Moreover, to better account for the interfacial adhesion, we include the van de Waals interactions by means of either the semi-empirical force fields by Grimme (DFT-D2 and DFT-D2*) or the self-consistent density functional optB88-vdW. We compare and discuss the results on the structural, electronic, and adhesion characteristics of the interface as obtained for pristine and oxygen-deficient Ag-supported MgO films in the 1–4 ML thickness range.

    Full Text Available In prepuberal girls vulvo-vaginitis are caused by germs of intestinal origin,mycetes, Gardnerella vaginalis, protozoa. Shigella is an uncommon agent able to induce valvovaginitis in children. We report the case of a 7-year-old girl with chronic vulvo-vaginitis caused by S. flexneri. Antibiotic Susceptibility Testing revealed that S. flexnery was sensible to cefotaxime, amoxicillin, imipenem, ciprofloxacin, but resistant to amikacin, cefazolin, gentamycin, ampicillin and tetracycline. A treatment with ciprofloxacin brought to a rapid resolution of all symptoms. At the follows up at 3 and 6 months the patient did not report symptoms of infection or articular cartilage abnormality; microbiological evaluations were also negative. Even if it is a single case report and other clinical trial may be performed in order to validate this hypothesis,we speculate that in patient with vulvo-vaginal infection living in environment with low hygiene care, a carefully microbiological evaluation of uncommon agents may be performed.

    A Reye Like Syndrome case occurred in a twelve year-old little girl with a previous familiar history is reported. The little patient was admitted in the pediatric ward for fever, vomiting and aspecific respiratory symptoms and developed very quickly a severe metabolic acidosis, alterations of consciousness, hypoxia, tissular hypoperfusion, multiple organ failure (MOF) and a fatal outcome. The postmortem diagnosis pointed out a methyl malonic acidaemia, a fairly frequent cause of acute metabolic distress, which may occur also in prepuberal age. The correct diagnostic and therapeutic approach of these cases is stressed since they need a prompt and careful monitoring in intensive care unit and a close cooperation among pediatricians, intensive care specialists and the nearest centre for the study of metabolic diseases.

    The use of 2,4-dinitrophenol (DNP) has regained popularity as a weight loss aid in the last two decades due to increased marketing to bodybuilders and the increasing availability of this banned substance via the Internet. 2,4-DNP is a drug of narrow therapeutic index and toxicity results in hyperthermia, diaphoresis, tachycardia, tachypnoea and possible cardiac arrest and death. Skin toxicity from 2,4-DNP has not been reported since the 1930s. We report a case of a 21-year-old bodybuilding enthusiast who presented with a toxic exanthem after taking 2,4-DNP, and describe the first skin biopsy findings in a case of 2,4-DNP toxicity. © 2014 The Australasian College of Dermatologists.

    Full Text Available ABSTRACT OBJECTIVE: Describe the clinical and laboratory profile, follow-up, and outcome of a series of cases of acute viral myositis. METHOD: A retrospective analysis of suspected cases under observation in the emergency department was performed, including outpatient follow-up with the recording of respiratory infection and musculoskeletal symptoms, measurement of muscle enzymes, creatine phosphokinase (CPK, lactate dehydrogenase (LDH, transaminases (AST and ALT, blood count, C-reactive protein, and erythrocyte sedimentation rate in the acute phase and during follow-up until normalization. RESULTS: Between 2000 and 2009, 42 suspected cases were identified and 35 (27 boys were included. The median age was 7 years and the diagnosis was reported in 89% in the first emergency visit. The observed respiratory symptoms were cough (31%, rhinorrhea (23%, and fever (63%, with a mean duration of 4.3 days. Musculoskeletal symptoms were localized pain in the calves (80%, limited ambulation (57%, gait abnormality (40%, and muscle weakness in the lower limbs (71%, with a mean duration of 3.6 days. There was significant increase in CPK enzymes (5507 ± 9180 U/L, LDH (827 ± 598 U/L, and AST (199 ± 245 U/L, with a tendency to leukopenia (4590 ± 1420 leukocytes/mm3. The complete recovery of laboratory parameters was observed in 30 days (median, and laboratory and clinical recurrence was documented in one case after 10 months. CONCLUSION: Typical symptoms with increased muscle enzymes after diagnosis of influenza and self-limited course of the disease were the clues to the diagnosis. The increase in muscle enzymes indicate transient myotropic activity related to seasonal influenza, which should be considered, regardless of the viral identification, possibly associated with influenza virus or other respiratory viruses.

    To describe a case of BK virus encephalitis with attempted direct antiviral therapy, review the reported cases of BK virus in the central nervous system, and report the novel use of intravenous cimetidine in place of oral probenecid to minimize the toxicities of intravenous cidofovir. A 36-year-old male with acute myelomonocytic leukemia and subsequent myelodysplastic syndrome underwent allogeneic hematopoietic stem cell transplant. His course was complicated by severe graft-versus-host disease involving his skin and gastrointestinal tract. Five weeks after transplantation, he developed fever and confusion. Magnetic resonance imaging was suggestive of limbic encephalitis and cerebrospinal fluid tested positive for BK virus. Therapy with intravenous cidofovir was thought to be indicated. Although probenecid is commonly used to minimize the toxicities of cidofovir, the patient's severe graft-versus-host disease raised concerns about absorption of oral medications. Based on animal models and pharmacokinetic data, intravenous cimetidine was used in place of oral probenecid. Despite these therapies, the patient's mental status did not improve. He developed progressive organ system failure, and care was ultimately withdrawn. BK virus is increasingly described as a cause of encephalitis. The majority of reported cases have occurred in immunocompromised patients and have generally had a poor outcome. This case describes attempted antiviral therapy using cidofovir, the antiviral agent used most frequently in other syndromes due to BK virus. Intravenous cimetidine is a novel modality used to minimize ocular and renal toxicities frequently seen with cidofovir, and we believe this warrants further investigation. BK virus may be a cause of encephalitis in immunocompromised hosts, and cidofovir represents a possible treatment option. Intravenous cimetidine can be considered to minimize toxicities associated with cidofovir use in patients unable to tolerate or absorb oral

    Proliferative myositis (PM) along with proliferative fasciitis and nodular fasciitis are a group of pseudosarcomatous myofibroblastic proliferations. Although the histologic presentation of each is almost identical, the magnetic resonance imaging (MRI) appearance of proliferative myositis is closer to that of inflammatory myopathies. We report a case of PM in which the imaging and histologic features combine typical findings of PM with unusual imaging features, suggesting of reactive (or nodular) fasciitis. (orig.)

    2016-06-01

    Full Text Available Systemic sclerosis (Ssc is an autoimmune connective tissue disease of unknown origin, characterized by progressive fibrosis of the skin and internal organs. Immune reactions taking part in Ssc pathogenesis may contribute to cancer development; therefore patients with risk factors for this disease require observation for a neoplastic process. On the other hand, symptoms of Ssc may be a mask of various cancers. Differentiating between the idiopathic form of Ssc and scleroderma-like paraneoplastic syndrome often causes a lot of difficulties. The article presents two cases of Ssc at the beginning of the disease after 60 years of age. The first case was diagnosed as Ssc, whereas in the second case the defined diagnosis was scleroderma-like syndrome in the course of colorectal cancer. This paper presents an analysis of differential diagnostic procedures which were performed and led to the final diagnosis, mentions types of cancers co-occurring with Ssc and suggests a screening scheme for cancer development in patients with a diagnosis of Ssc.

    Full Text Available Hyperbaric oxygen therapy (HBOT is a safe treatment, provided fulfilling certain rules of patient qualifications to treatment, as well as supervision over the course of therapy by qualified medical staff. Side effects reported in the literature are rare, and are usually mild and transient. Professional medical staff allows minimising the adverse events occurrence. The scale of complications is unknown, especially in Polish hyperbaric center. Careful analysis could be used to develop prevention procedures for patients of hyperbaric oxygen therapy. Hyperbaric Oxygen Centre and Wound Treatment in Bydgoszcz during 28 months performed hyperbaric oxygen therapy (HBOT in case of 423 patients. During this period, adverse events occurred occasionally. 17 cases have been reported. Authors described study case 77 year-old patient who was admitted due to non-healing wound-left lower abdomen (state after radiotherapy. During the fourth session, on decompression phase patient have had a generalized seizure (tonic-clonic. The decompression was stopped, the oxygen supply was disconnected but only after the drug administration seizures terminated. The most likely causative agent of the adverse reactions of the patient treated with HBOT was the oxygen toxic effect on the brain tissue. However, analyzing the circumstances of the seizure termination: phase of decompression at the pressure 2ATA and lack of oxygen disconnection response, it cannot be excluded other causes of this complication.

    Full Text Available Hemangiosarcoma (HSA is a type of cancer that has different clinical presentations and therefore different effects, since, depending on each case, different treatment options will exist. While in the case of cutaneous HSA the first line of treatment is always surgical removal of the tumor, metastatic foci should be sought and then perform chemotherapy, despite them having a low metastatic potential. Moreover, the low survival that exists in this type of cancer is a factor that should be communicated to those responsible for the pets, so that, with all available information, they can make a free and informed choice about the treatment they want for their pet, considering the financial commitment, survival time and quality of life associated with chemotherapy. This article describes the clinical case of a female greyhound dog of eight years of age that was brought to consultation for a skin tumor on the right hind limb in the distal tibia. She was diagnosed with noninvasive cutaneous HSA through histopathology, reason why the owners chose not to do the chemotherapy; however, 10 months later she presented recurrent skin lesions and a popliteal lymph node corresponding to hemangiosarcoma and hemangioma respectively, and three weeks later the patient developed cardiac tamponade due to a cardiac mass with associated spill, which resulted in her euthanasia.

    Polydactyly, a common hereditary condition with additional digits in hands and/or feet, is a very attractive model to appreciate clinical and genetic heterogeneity. In order to get an insight into its phenotypic manifestations, we ascertained a cohort of 313 independent families with polydactyly from Pakistan; 35% cases turned out to be familial while 65% were sporadic. In majority of the index cases, polydactyly was presented as an isolated digit defect. Preaxial polydactyly types were 48.24% and postaxial were 51.8%. Familial polydactylies mainly had bilateral and symmetrical presentations, whereas sporadic cases were mostly unilateral and less often symmetrical. In the 313 index subjects a total of 508 limbs with additional digits were recorded. Variable expression was evident as the involvement of upper limbs was more common than the lower, right hand than the left, and left foot than the right. The present cohort establishes interesting epidemiological attributes of polydactyly in the Pakistani population and highlights its extraordinary clinical heterogeneity. Molecular analyses of this cohort are anticipated to elucidate novel genetic factors involved in the origin of additional digits in the growing limb and may provide clues to the role of stochastic factors in the etiology of phenotypic variability in polydactyly. © 2013 John Wiley & Sons A/S.

    Transtibial amputation osteoplasty procedures were originally designed as a technique for achieving a functional end-bearing limb in the post-World War I era; the Ertl procedure is now often used as a reconstructive procedure for failed primary amputations. Modifications of the original periosteal sleeve-covering technique include the tibiofibular bone-bridging osteoplasty. The theoretical advantages to this procedure are highly debated among trauma surgeons. For the patient with a lower extremity injury that necessitates a transtibial amputation, there are many psychologic and physiologic factors to consider, and a persistently painful residual limb postamputation may be mentally and physically disabling. Although the advantages of these techniques may be unproven, they are fairly simple and add little additional operative time to the primary transtibial amputation. A surgeon who performs transtibial amputations should at least be aware of the osteoplasty techniques and how to perform them. The decision to use these techniques may then be made by the surgeon on a case-by-case basis, given the individual demands of the patient. This article presents a case report and outlines the use of the fibular bone-bridging osteoplasty technique in transtibial amputations.

    Full Text Available Objective: To describe the conditions and characteristics of the tracheostomy procedure in a tertiary health care unit and analyze its association with the recorded outcome. Materials and methods: A retrospective, observational and descriptive study that included patients operated in the Otorhinolaryngology Unit of the Northwest National Medical Center, Sonora, from August 2014 to August 2015. Fifty-two (52 complete clinical records of consecutive series of cases were reviewed, out of which 57% were men with an average age of 56.2 years old. Descriptive statistics was used to characterize the distribution, and the differences were evaluated by chi-square test and Student’s t-test. Results: Seventy-one percent (71% of the patients underwent surgery in an operating room and 29% in the ICU. In the latter, more than half of the cases had a tracheostomy (51.92%. Prolonged intubation was the main cause of 51% of the tracheostomy procedures. Complications reached 34.61% of the cases and included the following disorders in descending order: cannula occlusion, peristomal emphysema, hemorrhage, bilateral pneumothorax, decanulation and innominate fistula. These complications were significantly associated with obesity, prolonged endotracheal intubation and general anesthesia. Mortality occurred in 7.69% of the patients. Conclusions: No significant difference was found between complications occurred in an operating room and the ICU. Prolonged mechanical ventilation was the primary indication for tracheotomy. Decannulation was the main cause of complication. Moreover, BMI was a risk factor for complications. The mortality rate was 7.69%, which was more elevated compared to other studies.

    Histological examination was performed in 123 cats with primary nasal and paranasal sinus tumours; 117 had undergone surgical biopsy and six necropsy. Special stains and immunohistochemistry were performed on poorly differentiated cases. Ninety-two percent (113/123) of the tumours were malignant. There was an increased risk for old cats (mean age of 10.9 years), and a male predilection (59% males). Clinical signs and breeds varied with the histological type of tumour. Thirty-nine percent (48/123) of the cases presented with nasal discharge, 21% (26/123) with dyspnea, 20% (24/123) with facial swelling, and 15% (19/123) with epistaxis. Forty-three percent (53/123) of the tumours were of epithelial origin. Adenocarcinomas (18/53) and squamous cell carcinomas (17/53) were the most common epithelial tumours. Fifty percent (26/53) of the epithelial tumours originated from the pseudo-stratified respiratory epithelium of the nasal cavity, 28% (15/53) from the stratified squamous epithelium of the vestibule, 9% (5/53) from olfactory epithelium, 9% (5/53) from submucosal glands and 4% (2/53) from minor salivary glands. Malignant lymphoma (35/123) was the most common tumour. Seventy-one percent (25/35) of the malignant lymphomas were B-cell tumours and 29% (10/35) were T-cell tumours. Six cases of malignant lymphomas were proved to be epitheliotropic T-cell lymphomas. This is the first report of a primary nasal epitheliotropic T-cell lymphoma in cats.

    Nasopalpebral lipoma-coloboma syndrome is an extremely uncommon autosomal dominant condition characterized by congenital upper eyelid and nasopalpebral lipomas, colobomata of upper and lower eyelids, telecanthus, and maxillary hypoplasia. A few familial and sporadic cases of this malformation syndrome have been previously reported. Here, the clinical, radiological, and histopathological features of a sporadic Mexican patient with the nasopalpebral lipoma-coloboma syndrome are described. To our knowledge, this is the first time that craniofacial 3D computed tomography imaging was used for a detailed assessment of the facial lipoma. Copyright © 2013 Wiley Periodicals, Inc.

    We describe a case of temporal granulocytic sarcoma in a 26-year-old patient after apparent molecular remission of an acute myeloid leukaemia. He complained of otodynia with hearing loss and facial paralysis on the right side. He was treated with chemotherapy and self-transplant haematopoietic stem cells. He was cured clinically, molecular remission of the haematological processes was achieved, and he remained asymptomatic for three years. Facial paralysis and hearing loss associated with temporal GS should be treated with chemotherapy. Aggressive surgery may complicate the clinical course of the disease and it should be avoided.

    We describe the eleventh major outbreak of foodborne Trypanosoma cruzi transmission in urban Venezuela, including evidence for vertical transmission from the index case to her fetus. After confirming fetal death at 24 weeks of gestation, pregnancy interruption was performed. On direct examination of the amniotic fluid, trypomastigotes were detected. T. cruzi specific-polymerase chain reaction (PCR) also proved positive when examining autopsied fetal organs. Finally, microscopic fetal heart examination revealed amastigote nests. Acute orally transmitted Chagas disease can be life threatening or even fatal for pregnant women and unborn fetuses owing to vertical transmission. There is therefore an urgent need to improve national epidemiologic control measures.

    Osteogenesis imperfecta is the commonest connective tissue hereditary disease. Its clinical presentation has a wide spectrum of characteristics, which includes skeletal deformities and hearing loss. We describe three case reports of individuals carriers of this disease presenting with different patterns of hearing loss. Hearing loss prevalence and patterns are variable and have no clear relation with genotype. Its assessment at initial evaluation and posterior monitoring is essential to provide the best therapeutic alternatives. Copyright © 2012 Elsevier España, S.L. All rights reserved.

    Reye's syndrome is an acute disease characterised by encephalopathy and fatty degeneration of the liver that occurs almost exclusively in children. It can cause the death of the patient in up to a third of all cases, generally due to severe cerebral oedema. The aetiopathogenesis of this condition is uncertain and is usually preceded by a viral infection, generally from the influenza or varicella virus. Some studies have shown a strong epidemiological association between the ingestion of acetylsalicylic acid (ASA) during the viral infection and development of Reye's syndrome. We describe the case of a 20-month-old female who developed Reye's syndrome within the context of a viral infection and the ingestion of ASA. A hepatic biopsy study is appropriate in this syndrome. The patient presented a non-convulsive status during the acute phase and at one year developed Lennox-Gastaut syndrome. She died from pneumonia at the age of 18 years. In all patients with clinical features that suggest Reye's syndrome, inborn errors of metabolism that can mimic it must be precluded. Although the incidence of this syndrome has gone down considerably in recent years, it is important to keep it in mind as an early and aggressive diagnosis and treatment of cerebral hypertension will reduce the mortality rate and the sequelae.

    The role of Streptococcus pneumoniae as a causative agent of skin and soft tissue infections (SSTI) is unusual and its clinical interpretation is difficult. We describe here three cases of SSTI due to S. pneumoniae in patients admitted to the Provincial Pediatric Hospital of Misiones, Argentina that were detected during 10 years of invasive disease (ID) surveillance documented in 2010, 2011 and 2015. These cases involved two girls aged 8 and 7 months old, and a two-year-old male child with diagnoses of gluteal abscess, preseptal cellulites and pyoderma respectively. All the patients were eutrophic and in good general condition on admission; one of them was seropositive for HIV. Antimicrobial susceptibility and serotypes were framed within the local epidemiology of invasive pneumococcal disease. Despite its low frequency, S. pneumoniae as an etiological agent of SSTI must be considered. Our findings revalue the role of the diagnostic laboratory and contribute to document the behavior of this pathogen. Copyright © 2017 Asociación Argentina de Microbiología.

    Cancer is the second cause of death in Portugal right after cardio vascular diseases. In Portugal the incidence of oral and pharynx cancer (OPC) is higher than uterus and larynx cancers, and in US its frequency is higher than melanoma or uterus cancer, diseases that concern more population than oral cancer. The aim of this paper is to identify preferable anatomic location for oral cancer, mean age of patients, the use of tobacco and alcohol, histological characteristics, staging, type of therapeutics, presence of metastases and 1 and 5 year follow up. Data was collected from clinical charts of 365 cases from the Centro de Lisboa do Instituto Portugues de Oncologia with histological confirmation of malign tumor of the mouth. These cases are the total of oral malign tumors in the years of 1997, 1998 and 1999 in that institution. We observe that despite modern diagnostic and treatment techniques 37,9% of all patients died after first year with evidence of tumor. From all patients just 23,7% were free of disease after 5 years of treatment. Tongue was the principal region affected and the average age was 62, 25 years. It was concluded that 57, 8% of patient were smokers and 43,8% were alcohol drinkers. A high number of patients were submitted to radiotherapy either alone or with other treatment options.

    2016-04-01

    Full Text Available Brachydactyly is an inheritable autosomal genetic malformation, either dominant or recessive. This article describes a gypsy family presenting with congenital brachydactyly. The study was conducted at the Sanitary District of Guadix, in Granada, Spain. The study subjects were four siblings (two women and two men, members of the same family and belonging to the Roma community. Demographic and genetic data were collected. With some variability, they had the phenotypic manifestation of brachydactyly. Radiographic data revealed that it was type A4 brachydactyly, but one of them featured a blend of A4 with E, or perhaps it is a new unclassified variety. All cases showed similar abnormalities in the feet. Besides, they are obese, and have dyslipidemia and different degrees of consanguinity.

  9. Generalized aggressive periodontitis in prepubertal age: description and comparison of two cases

    Full Text Available Aggressive periodontitis is a rare form of periodontal disease and it can involve both the deciduous dentition and the permanent one. It causes a rapid loss of periodontal attachment. The paper aims to describe two cases of severe generalized prepubertal periodontitis: the first child doesn’t suffer from neither systemic diseases nor alteration of functionality of polymorphonuclear and periodontal disease involved both his deciduous dentition and the first permanent molars. The second child had a deficiency of functionality of polymorphonuclear but periodontal disease involved only primary dentition thanks to his immediate improvement of home dental hygiene. This comparison shows the importance of early diagnosis and especially of optimal dental oral hygiene. Infant healthcare professionals, as pediatric dentists and pediatricians, should have the necessary knowledge for early and correct diagnosis and clinical management of disease.

    Severe facial and scalp dermatitis following the use of permanent hair dyes has been reported in several cases. Para-phenylenediamine (PPD) is known as a potent contact allergen, and PPD is allowed in hair dye at a concentration of 6%. Hair dye reactions are usually diagnosed by the patients...... were patch tested and all were found positive to PPD. Our data presented here clearly show that PPD and its derivatives in hair dye at the present concentrations presents a significant health risk for the population. Furthermore, the severe acute allergic skin reactions are often misdiagnosed...... themselves, and adverse reactions to hair dye may not necessarily be recorded by the health care system, unless the reactions are especially severe. Based on this assumption, we suspected that hair dye dermatitis was occurring more frequently than reported in the literature. Consumer complaint-based data...

    1998-01-01

    Lesbians and gay men are turning to the courts to recognize their family relationships. In this article every reported court decision where a lesbian or gay couple has successfully completed a second-parent adoption is reviewed to analyze the presentation and judicial analysis of the petitioning parties in conjunction with the current debates within family theory. Traditional family theorists argue that the contemporary family is in transition but will always be recognizable as the traditional family; postmodern theorists argue that the traditional "family" is a fiction. Results from this study indicate that judges in second-parent adoption cases rely on a traditional definition and vision of the family in evaluating the gay and lesbian petitioners before them.

    Annalisa Di Cesare

    2012-01-01

    Full Text Available We report on a rare case of Morquio syndrome, an autosomal recessive mucopolysaccharidosis including type IVA, a deficiency of N-acetylgalctosamine-6-sulfatase and type IVB a deficiency of β-galactosidase. A 43-year-old female patient affected by IVB Morquio syndrome underwent instrumental investigation. Conventional plain films of the entire spine, pelvis, chest and knees together with magnetic resonance imaging of the entire column, hip, knees, and ankles demonstrated the characteristics of skeletal changes of this disease. The main abnormalities were platyspondily and hypoplasia of the odontoid process, genua valga deformity and severe multiple degenerative changes of the hips, knees, and ankle joints. Radiographs and above all magnetic resonance imaging are crucial to provide substantial information about the gravity, evolution of the skeletal and joints changes, and the rehabilitation strategies to be followed.

    Fibropapillomatosis (FP) is a debilitating neoplastic disease that affects all species of hard-shelled sea turtles, including loggerhead turtles Caretta caretta. FP can represent an important clinical concern in rehabilitating turtles, since managing these infectious lesions often requires special husbandry provisions including quarantine, and FP may affect clinical progression, extend rehabilitation duration, and complicate prognoses. Here we describe cases of rehabilitating loggerhead turtles with FP (designated FP+). Medical records of FP+ loggerhead cases from 3 sea turtle rehabilitation facilities in the southeastern USA were reviewed. Between 2001 and 2014, FP was observed in 8 of 818 rehabilitating loggerhead turtles (0.98% overall prevalence in admitted patients). FP+ loggerhead size classes represented were large juvenile (straight carapace length, SCL: 58.1-80 cm; n=7) and adult (SCL>87 cm; n=1). Three turtles presented with FP, and 5 developed tumors during rehabilitation within a range of 45 to 319 d. Sites of new tumor growth included the eyes, sites of trauma, neck, and glottis. FP+ turtles were scored as mildly (3/8), moderately (4/8), or heavily (1/8) afflicted. The mean total time in rehabilitation was 476±355 d (SD) (range: 52-1159 d). Six turtles were released without visible evidence of FP, 1 turtle was released with mild FP, and 1 turtle with internal FP was euthanized. Clinical decision-making for FP+ loggerhead patients can be aided by such information as time to tumor development, anatomic locations to monitor for new tumor growth, husbandry considerations, diagnostic and treatment options, and comparisons to FP in rehabilitating green turtles Chelonia mydas.

  14. Acute gouty arthritis and rapidly progressive renal failure as manifestation of multiple myeloma: clinical case description

    O.V. Gudym

    2017-08-01

    Full Text Available The article describes a clinical case of multiple myeloma in 78-year-old man, its clinical onset was as an acute attack of gout. The patient was admitted to hospital due to the development of the first acute attack of gout. The attack was characterized by polyarthricular joint lesion of the upper and lower extremities, pronounced inflammatory reaction, insufficient response to the use of non-steroidal anti-inflammatory drugs, and a high level of hyperuricemia. The serum uric acid concentration ranged from 636 to 712 μmol/l. The study of the synovial fluid of the inflamed knee joint made it possible to reveal uric acid crystals and to confirm the diagnosis of acute gouty arthritis. Simultaneously, the patient had significant renal impairment: creatinine was 574 μmol/l, urea — 39.9 mmol/l, glomerular filtration rate according to CKD-EPI — 8 ml/min. The daily proteinuria was 1.8 g. A retrospective assessment of laboratory parameters allowed to reveal completely normal indicators of renal function 6 months ago. Considering the development of acute gouty arthritis, its polyarticular nature, persistent course, rapid involvement of new joints, high uric acid levels during an acute attack exceeding 600 μmol/l (10 mg/dL, rapid development of renal failure within 6 months until the terminal stage, it was suggested the secondary nature of gout on the background of kidney damage by another pathological process. Further clinical, laboratory and instrumental studies allowed verifying multiple myeloma with renal damage. Bence Jones protein in the urine was not detected, there was also no evidence of hyperproteinemia. However, pain in the spine, ribs and chest was the basis for carrying out an X-ray study of the bones of the skeleton. Changes in the skeleton typical for multiple myeloma have been identified. Myelogram showed a high content of plasma cells (21.1 %, electrophoresis of blood proteins showed a high M-gradient (30.42 %, and a cytochemical

  15. The diffusion of the distance Entomology Master's Degree Program at the University of Nebraska Lincoln: A descriptive case study

    Hubbell, Jody M.

    This study explored three selected phases of Rogers' (1995) Diffusion of Innovations Theory to examine the diffusion process of the distance Entomology Master's Degree program at the University of Nebraska, Lincoln. A qualitative descriptive case study approach incorporated semi-structured interviews with individuals involved in one or more of the three stages: Development, Implementation, and Institutionalization. Documents and archival evidence were used to triangulate findings. This research analyzed descriptions of the program as it moved from the Development, to the Implementation, and finally, the Institutionalization stages of diffusion. Each respective stage was examined through open and axial coding. Process coding identified themes common to two or more diffusion stages, and explored the evolution of themes from one diffusion stage to the next. At a time of significant budget constraints, many departments were faced with the possibility of merger or dissolution. The Entomology Master's Degree Program evolved from being an entrepreneurial means to prevent departmental dissolution to eventually being viewed as a model for the development of similar programs across this university and other institutions of higher education. During this evolution, the program was reinvented to meet the broader needs of industry and a global student market. One finding not consistent with Rogers' model was that smaller, rather than larger, departmental size contributed to the success of the program. Within this small department, faculty members were able to share their experiences and knowledge with each other on a regular basis, which promoted greater acceptance of the distance program. How quality and rigor may be defined and measured was a key issue in each respective stage. In this specific case, quality and rigor was initially a comparison of on-campus and distance course content and then moved to program-based assessment and measures of student outcomes such as job

    To describe a technique for registering the positions of multiple dental implants using a system based on photogrammetry. A case is presented in which a prosthetic treatment was performed using this technique. Three Euroteknika® dental implants were placed to rehabilitate a 55-year-old male patient with right posterior maxillary edentulism. Three months later, the positions of the implants were registered using a photogrammetry-based stereo-camera (PICcamera®). After processing patient and implant data, special abutments (PICabutment®) were screwed onto each implant. The PICcamera® was then used to capture images of the implant positions, automatically taking 150 images in less than 60 seconds. From this information a file was obtained describing the relative positions - angles and distances - of each implant in vector form. Information regarding the soft tissues was obtained from an alginate impression that was cast in plaster and scanned. A Cr-Co structure was obtained using CAD/CAM, and its passive fit was verified in the patient's mouth using the Sheffield test and the screw resistance test. Twelve months after loading, peri-implant tissues were healthy and no marginal bone loss was observed. The clinical application of this new system using photogrammetry to record the position of multiple dental implants facilitated the rehabilitation of a patient with posterior maxillary edentulism by means of a prosthesis with optimal fit. The prosthetic process was accurate, fast, simple to apply and comfortable for the patient.

    The prevalence of pelvic fracture (PF) due to frailty is increasing, leading to an increase in functional impairment in the patient, as well as increasing morbidity and mortality. The aim of the present study is to gain knowledge about the sociodemographic characteristics, as well as the functional features, of patients admitted to hospital with PF and evaluated by a Geriatrics department. The functional burden of PF and the potential influence of geriatric interventions are also assessed. A retrospective study conducted between 1995 and 2015 on all patients older than 65 years old with PF admitted to the Traumatology department, and then assessed in the Geriatrics Department. Sociodemographic information was also collected (age, gender and place of residence), as well as data from the geriatric assessment (baseline situation and at hospital admission), hospital stay, within hospital mortality, and discharge. The study included 271 patients with a mean age of 81.1±7 years, and mainly women (81.2%). The median hospital stay was 9 days (interquartile range 5 to 14 days). The ability to walk independently decreased after PF from 72.3% to 3.6%. Severe disability cases increased in activities of daily living from 7.9% to 79.5%. Within hospital mortality was 2.2%. As regards medical follow-up consultations, the mean length of stay was significantly reduced compared to the assessment consultations (10.0±7.8 vs 16.1±12.0 days, P<.001) CONCLUSION: PF patients evaluated by the Geriatrics Department were mainly women, with advanced age, and a severe functional impairment secondary to PF. The intervention of a geriatrician could contribute to optimise hospital resources. Copyright © 2017 SEGG. Publicado por Elsevier España, S.L.U. All rights reserved.

    Objective: To conduct a descriptive analysis on 31 cases of children with floating elbow who were attended at our clinic between 1994 and 2009, and to review the literature relating to this topic. Methods: Data were obtained through examining the medical records. The following variables were used: age, gender, side, mechanism, type of fracture, classification, treatment and complications. Results: Twenty-four patients (77.4%) were male and seven (22.6%) were female. The mean age was 8.5 (± 3.2) years, ranging from one to 14 years. The left side was predominantly affected (67.7%). The commonest injury mechanism was a fall from a height (74.2%). All the supracondylar fractures were Gartland type III. Distal radius fractures alone, of Salter-Harris type II, were diagnosed in 22 patients (71%). Open fractures occurred in 22 cases (71%). Closed reduction and application of a plaster cast for a closed fracture of the distal radius was performed in two patients (6.45%). Simultaneous conservative treatment for two fractures was not used. Sixteen supracondylar fractures (54.8%) were fixed using crossed wires, at 90° to each other, and in 14 cases (45.16%), an intramedullary wire was used together with another wire introduced through the lateral epicondyle at 45°. The following complications were observed: deformed consolidation (10%), nerve injuries (6%), compartment syndrome (3%) and pin path infection (16%). Conclusions: This is an uncommon injury that in most cases results from high-energy trauma. Surgical treatment for both fractures is recommended by most authors. Ulnar nerve injuries were correlated with the fixation method, but no neurological injuries were triggered by the initial trauma. PMID:27027045

    Full Text Available Human infected avian influenza (H10N8 is an acute infectious respiratory tract infection caused by JX346-H10N8. The reported case in this paper is the globally first case report about radiological description of human infected avian influenza (H10N8 virus related pneumonia. The patient showed an epidemiological history of contacts to living poultries and the incubation period lasted for 4 days. The condition was clinically characterized by fever, cough, chest distress and obvious hypoxia. CT scan demonstrated the lungs with large flake of hyper-intense consolidation, confined patch of ground glass opacity, dilated bronchi, predominantly dorsal thickening of the interlobular septum, and other types of lesions related to interstitial pulmonary edema. Meanwhile, accompanying interlobar effusion, infrapulmonary effusion and pleural effusion were demonstrated in a small quantity by CT scan. Human infected avian influenza (H10N8 related pneumonia should be differentiated from pneumonia induced by human infected avian influenza viruses H5N1 and H7N9. No characteristic key points for radiological differentiation have been found. And its definitive diagnosis should be based on the etiological examination.

    This article describes a new, brief exposure-based psychotherapy known as Accelerated Resolution Therapy (ART) that is currently being evaluated as a treatment for combat-related post-traumatic stress disorder (PTSD). We describe a case report of an Army veteran with combat-related PTSD who was treated with 2 sessions of ART and experienced significant clinical improvement. We then discuss the theoretical basis and major components of the ART protocol, including use of lateral left-right eye movements, and differentiate ART with evidence-based psychotherapies currently endorsed by the Department of Defense and Veterans Administration. The number of military personnel who have served in the wars in Iraq and Afghanistan and are afflicted with PTSD is likely in the hundreds of thousands. The ART protocol, which is delivered in 2 to 5 sessions and without homework, uses the psychotherapeutic practices of imaginal exposure and imagery rescripting (IR) facilitated through sets of eye movements. In addition to its brevity, a novel component of ART is use of IR to "replace" negative imagery (and other sensations) with positive imagery. This theoretical description of ART and single case report provide a rationale for future formal evaluation of ART for treatment of military-related PTSD.

    To assess the perioperative evolution of the nutritional status of head and neck surgical patients. Prospective, descriptive case series. Fifty-four patients candidates for total or partial laryngectomy for malignancy of the neck tract without a past of neck surgery. The nutritional status of all patients hospitalized for total pharyngolaryngectomy, total or partial laryngectomy was assessed by 1) clinical parameters including weight (W), weight variation (WV, percentage of loss), Body Mass Index (BMI), triceps skin fold measurement (T), midarm circumference (M), and 2) biological parameters such as serum albumin (SA), transthyretin (TTR), lymphocytes (Ly). These parameters were noted at the time of diagnostic laryngoscopy (T1), the day before surgery (T2), and 10 days afterward (T3) when patients were authorized to eat normally. All patients had enteral nutrition (EN) support (35 kcal/kg/day) starting at D1 and for 10 days afterward. Only complete data per patient were analyzed. 24 patients were excluded. During the 21 days [7-53] preoperative period (T1-T2), WV was (6.6% [-8,1-+20.0] [T2] vs. 4.7% [-12,9-+20.0] [T1], pnutritional status in malignancy head and neck surgical patients seems to be best assessed by loss weight. It worsened mainly during the postoperative period even if a well-conducted EN was performed as defined by the French consensus conference.

    Description of the Disposal System sits within Posiva Oy's Safety Case 'TURVA-2012' report portfolio and has the objective presenting the initial state of the disposal system for the safety case for the disposal of spent nuclear fuel at Olkiluoto, Finland. Disposal system is an entity composed of a repository system and surface environment. The repository system includes the spent nuclear fuel, canister, buffer, backfill, and closure components as well as the host rock. The repository system components have assigned safety functions (except for the spent nuclear fuel) and are subject to requirements. The initial state is presented for each component, and references to the main supporting reports are given to guide the reader for more details. Conditions for each component vary in time and space, due to the time of emplacement and due to the tolerances set for the compositions, geometries and other properties depending on the component. The disposal operation is foreseen to commence {approx} 2020. At the beginning of the postclosure period, around 2120, all the engineered components have been installed and the operation is finalised. The system evolution during the operational phase is discussed in detail in Performance Assessment. The initial state for the host rock is defined to be essentially equal to the baseline conditions prior to starting the construction of the underground characterisation facility ONKALO. For the surface environment, the initial state is the present conditions prevailing. For any other component of the disposal system, the initial state is defined as the state it has when the direct control over that specific part of the system ceases and only limited information can be made available on the subsequent development of conditions in that part of the system or its near field.

    Internationalization of practical training in health and social care study programs is an important aspect of higher education. However, field mentors' and classroom teachers' competence in guiding culturally diverse students varies widely in European countries, and the majority does not have enough training in guiding foreign students. This study aimed to examine which factors enhance the efficacy of international practical placement experiences in health and social care study programs. A qualitative descriptive case study design was used. The study was conducted at six higher education institutions-two in Finland and one in Croatia, Estonia, the Netherlands and Slovenia. A convenience sample of 14 mentors, 15 teachers and 14 students with international experiences from six higher education institutions which are part of the Bologna Process was recruited. The data were collected from six focus groups using a semi-structured questionnaire based on a literature review. Each higher education institution conducted one group interview that was tape-recorded, transcribed and analysed for themes. Participants made several recommendations for enhancing the practical placement experience of students, teachers, and mentors. Most recommendations dealt with practical supervision of students. Three major themes noted were: 'Attitudes towards internationalization of practical placements', 'Factors impacting the international placement experience', and 'Pedagogical methods used and structural support available for internationalization.' The study highlights the need for strengthening the multicultural knowledge and skills of mentors and teachers. The findings provide practical guidelines for improving the international placement experience across health and social care fields. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Orbital cellulitis is an infrequent complication of acute ethmoiditis possibly leading to life- or visual-threatening complications. Despite its natural history is well known, its clinical evolution may widely vary among patients, and even in the most favourable cases long-term sequelae may persist. We here provide a step-by-step iconographic description of a periorbital and orbital cellulitis occurring in a child with ipsilateral acute rhinosinusitis. Our report shows that an unusual long-term evolution of periorbital and orbital cellulitis is possible also in apparently favourable cases.

    Mojca Šorli

    2013-05-01

    Full Text Available The present paper focuses on ways in which the pragmatic (functional meaning that arises from various contextual features, known in corpus linguistics as semantic prosody, can become an integral part of lexicographical descriptions as they are represented in the Slovene Lexical Database (SLD. This is particularly important for the treatment of phraseology and idiomatics. First, the theoretical background is provided, with the focus on the prototype theory and its practical implications for monolingual lexicography. A parallel is drawn with the model of meaning analysis in the SLD. The second part begins with a brief introduction to semantic prosody and continues with an analysis of monolingual meaning descriptions in the SLD against a number of authentic corpus examples, investigating how their pragmatic components have been identified. The analysis of corpus data shows that pragmatics is an important contributor to the process of sense discrimination in works of lexical and lexicographic relevance.

    Full Text Available Abstract Background In Germany, case management in a palliative care unit was first implemented in 2005 at the Department of Palliative Medicine at the University Hospital Cologne. One of the purposes of this case management is to deal with enquiries from patients and their relatives as well as medical professionals. Using the Case Management Process Model of the Case Management Society of America as a reference, this study analysed (a how this case management was used by different enquiring groups and (b how patients were identified for case management and for palliative care services. The first thousand enquiries were analysed considering patient variables, properties of the enquiring persons and the content of the consultations. Results Most enquiries to the case management were made by telephone. The majority of requests regarded patients with oncological disease (84.3 %. The largest enquiring group was composed of patients and relatives (40.8 %, followed by internal professionals of the hospital (36.1 %. Most of the enquiring persons asked for a patient’s admission to the palliative care ward (46.4 %. The second most frequent request was for consultation and advice (30.9 %, followed by requests for the palliative home care service (13.3 %. Frequent reasons for actual admissions were the need for the treatment of pain, the presence of symptoms and the need for nursing care. More than half of the enquiries concerning admission to the palliative care ward were followed by an admission. Conclusions Case management has been made public among the relevant target groups. Case management as described by the Case Management Process Model helps to identify patients likely to benefit from case management and palliative care services. In addition, with the help of case management palliative patients may be allocated to particular health care services.

    Purpose This study provides descriptive epidemiological data, such as the percentage of cases diagnosed, crude incidence rate (CIR), and age-standardized incidence rate (ASIR) of ovarian cancer in Saudi Arabia from 2001–2008. Patients and methods A retrospective descriptive epidemiological analysis of all ovarian cancer cases recorded in the Saudi Cancer Registry (SCR) from January 2001–December 2008 was performed. The data were analyzed using descriptive statistics, analysis of variance tests, Poisson regression, and simple linear modeling. Results A total of 991 ovarian cancer cases were recorded in the SCR from January 2001–December 2008. The region of Riyadh had the highest overall ASIR at 3.3 cases per 100,000 women, followed by the Jouf and Asir regions at 3.13 and 2.96 cases per 100,000 women. However, Hail and Jazan had the lowest rates at 1.4 and 0.6 cases per 100,000 women, respectively. Compared to Jazan, the incidence rate ratio for the number of ovarian cancer cases was significantly higher (P<0.001) in the Makkah region at 6.4 (95% confidence interval [CI]: 4.13–9.83), followed by Riyadh at 6.3 (95% CI: 4.10–9.82), and the eastern region of Saudi Arabia at 4.52 (95% CI: 2.93–6.98). The predicted annual CIR and ASIR for ovarian cancer in Saudi Arabia could be defined by the equations 0.9 + (0.07× years) and 1.71 + (0.09× years), respectively. Conclusion We observed a slight increase in the CIRs and ASIRs for ovarian cancer in Saudi Arabia from 2001–2008. Riyadh, Jouf, and Asir had the highest overall ASIR, while Jazan and Hail had the lowest rates. Makkah, Riyadh, and the eastern region of Saudi Arabia had the highest incidence rate ratio for the number of ovarian cancer cases. Further analytical studies are required to determine the potential risk factors of ovarian cancer among Saudi women. PMID:25028565

    Full Text Available Wakefulness, rapid eye movement (REM and non-REM sleep are not always mutually exclusive conditions, as commonly assumed. In some cases, the declaration of any state may be incomplete and states can fluctuate rapidly, resulting in peculiar behavioural syndromes such as narcolepsy, REM sleep behaviour disorder and status dissociatus. We briefly introduce this topic and discuss three suggestive clinical cases.

    The extensive time and cost associated with conventional sensory profiling methods has spurred sensory researchers to develop rapid method alternatives, such as Napping® with Ultra-Flash Profiling (UFP). Napping®-UFP generates sensory maps by requiring untrained panellists to separate samples based on perceived sensory similarities. Evaluations of this method have been restrained to manufactured/formulated food models, and predominantly structured on comparisons against the conventional descriptive method. The present study aims to extend the validation of Napping®-UFP (N = 72) to natural biological products; and to evaluate this method against Descriptive Analysis (DA; N = 8) with physiochemical measurements as an additional evaluative criterion. The results revealed that sample configurations generated by DA and Napping®-UFP were not significantly correlated (RV = 0.425, P = 0.077); however, they were both correlated with the product map generated based on the instrumental measures (P Napping®-UFP were driven by different sensory attributes, indicating potential structural differences between these two methods in configuring samples. Overall, these findings lent support for the extended use of Napping®-UFP for evaluations of natural biological products. Although DA was shown to be a better method for establishing sensory-instrumental relationships, Napping®-UFP exhibited strengths in generating informative sample configurations based on holistic perception of products. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Percutaneous gastrostomy, is the procedure of choice to provide enteral access in patients requiring nutritional support in this way in the long run, relegating the surgical gastrostomy. We present three patients requiring percutaneous gastrostomy for nutritional support. In two cases was performed endoscopic gastrostomy and another one using interventional radiology. While performing percutaneous gastrostomy clinical incidents were not detected, but when trying the replacement of gastrostomy tubes, showed the presence of gastrocolic fistula that caused failure or turnover in one case, or abdominal pain and diarrhea in the two other cases. Despite being a safe technique, should be done a proper patient selection in order to minimize the potential complications that may occur, as gastrocolic fistula, recommending in doubtful cases test of image such CT (computerized Tomography).

    Three important elements of the World Health Organization (WHO) definition of palliative care are: 1) it includes patients who may have cure or life prolongation as treatment aims besides palliative care; 2) it is not exclusively for cancer patients; and 3) it includes attention to the medical, psychological, social, and spiritual needs of the patients and their families. Case managers (nurses with expertise in palliative care) may assist generalist primary care providers in delivery of good palliative care. This study investigates the referral of patients to case managers in primary care with regard to the three elements mentioned: diagnosis, treatment aims, and needs as reflected in reasons given for referral. In this cross-sectional survey in primary care among case managers and referrers to case management, case managers completed questionnaires for 687 patients; referrers completed 448 (65%). Most patients referred have a combination of treatment aims (69%). Life expectancy and functional status of patients are lower for those with a treatment aim of palliation. Almost all (96%) of those referred are cancer patients. A need for psychosocial support is frequently given as a reason for referral (66%) regardless of treatment aim. Referrals to case managers reflect two of three elements of the WHO definition. Mainly, patients are referred for support complementary to medical care, and relatively early in their disease trajectory. However, most of those referred are cancer patients. Thus, to fully reflect the definition, broadening the scope to reach other patient groups is important.

    The Netherlands and Belgium legalized euthanasia in 2002. In this study we describe and compare cases of reported euthanasia and physician-assisted suicide in the first 5 years of legislation. The databases of the cases reported in Belgium and the Netherlands were made available by the review committees. We compared characteristics of all cases reported between September 2002-December 2007. In the Netherlands 10,319 cases were reported, in Belgium 1917. Gender and age distributions were similar in both countries. Most patients suffered from cancer (83-87%), but patients more often suffered from diseases of the nervous system in Belgium (8.3% vs. 3.9%). In the Netherlands, reported euthanasia more often occurred at home compared with Belgium (81% vs. 42%), where it occurred more often in hospital (52% vs. 9%). In the Netherlands, all cases were based on the oral request of a competent patient. In Belgium, 2.1% of the reported cases was based on an advance directive. We conclude that countries debating legislation must realise that the rules and procedures for euthanasia they would agree upon and the way they are codified or not into law may influence the practice that develops once the legislation is effected or what part of that practice is reported.

    Wilson's disease (WD) is a rare autosomal-recessive disorder characterized by a mutation in the ATP7B gene, located on chromosome 13, which encodes a protein involved in the metabolism of copper. We described the case of an Indian male with a history of polydipsia and polyuria, related to hypercalciuria and consequent nephrocalcinosis. The symptoms began at the age of five years old, but he was not diagnosed with WD until he reached an adolescent age. We started therapy with D-Penicillamine, B-vitamin complex and recommended a low copper diet. Renal involvement in Wilson's disease, characterizing by hypercalciuria, was firstly reported by Litin in 1959. Our case was different and peculiar from the previously described cases because the patient presented a very long history (10 years) of permanent hypercalciuria without any acute episode of nephrolithiasis.

    Raman-induced frequency shift of ultrashort pulses have been studied extensively for the soliton propagation regime. Here we derive explicit analytic expressions for the evolution of Raman-induced frequency shift in much less studied case of non-soliton ultrashort pulses. Pulse spectra may belong to any region of group velocity dispersion including zero group dispersion point. The analysis is based on the moment method. Obtained expressions fit well to the numerical solution of the nonlinear wave equation. - Highlights: • Explicit analytic formulas for the evolution of Raman-induced frequency shift are derived in the case of non-soliton pulses. • Dynamics of non-soliton ultrashort pulses in the cases of positive and zero group dispersion is considered. • The deceleration and the saturation of Raman-induced frequency shift are analyzed. • The calculation relies on the moment method and fit well to the numerical solution of the nonlinear wave equation.

    Hereditary breast and ovarian cancer syndrome is an autosomal dominant disease caused primarily by germline mutations in the BRCA1 or BRCA2 gene. Rare cases of double heterozygosity for BRCA1 and BRCA2 mutations have been reported quite exceptionally in non-Ashkenazi individuals. We describe the case of a woman who developed a bilateral breast cancer, discovered concomitantly, at 46 years old. Biopsies confirmed the presence of two breast cancers with distinct histology. BRCA analysis was tested due to a positive family history of breast cancer, and two pathogenic monoallelic mutations were detected, one in the BRCA1 gene and one in the BRCA2 gene. There is no known Ashkenazi Jewish ancestry. We report the first description of a never described double heterozygosity for BRCA1 and BRCA2 pathogenic variants in a French metastatic breast cancer patient, with two distinct histology, and two distinct mutations.

    Full Text Available Cherubism is a rare familial disease that occurs between the ages two and five years and regresses after puberty. Most of the cherubism cases show familial history, but there are some cases without familial histories of disorder. A two-year-old boy with a painless symmetrical progressive swelling of the jaws had visited maxillofacial radiology department. Panoramic radiograph revealed well-defined multilocular, radiolucent areas of both jaws. Computed tomography of the jaws showed well-defined, bilateral, multilocular, expansile lesions with thinning of cortical plate of maxilla and mandible and displacing the unerupted first molar anteriorly. Clinical, radiologic, and histopathologic characteristics confirmed the diagnosis of cherubism.

    Cherubism is a rare familial disease that occurs between the ages two and five years and regresses after puberty. Most of the cherubism cases show familial history, but there are some cases without familial histories of disorder. A two-year-old boy with a painless symmetrical progressive swelling of the jaws had visited maxillofacial radiology department. Panoramic radiograph revealed well-defined multilocular, radiolucent areas of both jaws. Computed tomography of the jaws showed well-defined, bilateral, multilocular, expansile lesions with thinning of cortical plate of maxilla and mandible and displacing the unerupted first molar anteriorly. Clinical, radiologic, and histopathologic characteristics confirmed the diagnosis of cherubism. PMID:28105052

    This paper reports a pilot study of Context Evaluation using a self-developed questionnaire distributed among engineering undergraduates at a university under study. The study aims to validate the self-developed questionnaires used in the Context evaluation, a component in the CIPP Model. The Context evaluation assesses background information for needs, assets, problems and opportunities relevant to beneficiaries of the study in a defined environment. Through the questionnaire, background information for the assessment of needs, assets and problems related to the engineering undergraduates' perceptions on the teaching and learning of technical oral presentation skills was collected and analysed. The questionnaire was developed using 5-points Likert scale to measure the constructs under study. They were distributed to 100 respondents with 79 returned. The respondents consisted of engineering undergraduates studied at various faculties at one technical university in Malaysia. The descriptive analysis of data for each item which makes up the construct for Context evaluation is found to be high. This implied that engineering undergraduates showed high interest in teaching and learning of technical oral presentation skills, thus their needs are met. Also, they agreed that assets and facilities are conducive to their learning. In conclusion, the context evaluation involving needs and assets factors are both considerably important; their needs are met and the assets and facilities do support their technical oral presentation skills learning experience.

    2016-09-02

    Pathologic increase in bone marrow reticulin fibrosis can be present in many malignant hematopoietic diseases. In acute leukemia, one-third of patients have some degree of marrow reticulin fibrosis at presentation, which is thought to be related to cytokine release from blasts. Marrow fibrosis is particularly common in acute megakaryoblastic leukemia, while this change is rarely seen in acute promyelocytic leukemia. Six case reports of acute promyelocytic leukemia with marrow reticulin fibrosis have been described so far in the literature. Herein, we present three cases of classical acute promyelocytic leukemia with increased marrow reticulin fibrosis encountered in our institution, summarizing their clinicopathologic features, treatment, and outcome to date. Awareness of the features of acute promyelocytic leukemia with marrow reticulin fibrosis is important as it may guide treatment options.

    Full Text Available Abstract Background Extragonadal localization of germ cell tumors (GCTs is rare; to the best of our knowledge, a location in the soft tissue of the arm has never been previously reported in the literature. Case presentation We report the case of a 37-year-old man who presented with a primary malignant mixed non-seminomatous GCT (teratocarcinoma variety in the right arm, treated by a combination of cisplatin-based chemotherapy and surgery. After 18 months of close follow-up, no locoregional recurrence or distant metastases have been detected. Conclusions A combination of chemotherapy and surgery is the most appropriate treatment strategy for extragonadal GCTs, to ensure both local and systemic control.

    N-methyl-D-aspartate receptor encephalitis is an autoimmune encephalitis relationated or not with a neoplasm. Although its incidence is unknown, probably remains underdiagnosed. Epidemiological studies place it as the second cause of immune-mediated encephalitis and the first in patients aged less of 30 years. It shows neuropsychiatric symptoms and autonomic instability. After diagnosis, based on the detection of antibodies in serum or cerebrospinal fluid, an occult malignancy must be investigated. While increasing number of cases have been diagnosed and the important role of this receptor in general anesthesia mechanisms, the interaction of the disease with anesthetic agents and perioperative stress is unknown. We describe the case of a patient with encephalitis associated to ovarian teratoma that underwent gynaecological laparoscopy.

    1994-01-01

    The features and clinical course of chronic balanitis in 5 patients are presented. In each case, histological examination of a cutaneous biopsy sample showed pronounced features of human papillomavirus (HPV) infection. In addition, HPV DNA was demonstrated in each biopsy specimen by a polymerase chain reaction and was found to be type 6 by Southern blot hybridization in 4 of the cases. Although the association of histological features of HPV infection with balanitis does not prove that HPV is causal, the failure to find other causes, the prolonged and distressing symptoms, and the ineffectiveness of topical steroids in improving symptoms, all suggest the importance of HPV infection. While effective treatment needs to be sought and developed, the response of one patient to oral isotretinoin suggests that this agent may be appropriate for a larger trial.

    Full Text Available Background: Urinary myiasis is a form of myiasis caused mainly by larvae of Fannia scalaris, Musca, Sarcophaga, Lucilia, Wohlfahrtia, Calliphora, and rarely by Eristalis and Clogmia albipunctata.Methods: This report presents a case of female patient complaining of dysuria and frequency of micturition associ­ated with intermittent passage of small, motile, dark-colored worm-like organisms in urine. She was a married housewife aged 24 years old referred from the Tropical Outpatient Clinic of Beni-Suef University Hospital, Egypt. The patient was subjected to a full questionnaire sheet and investigations such as CBC, stool and urine analysis and uri­nary ul­traso­nography. Collected larvae and pupae from urine samples were examined macroscopically and micro­scopically.Results: The examined larvae and pupae belonged to C. albipunctata. Ivermectin was prescribed to the patient with complaint withdrawal and complete disappearance of the larvae from urine.Conclusion: This study reports the first case of urinary myiasis caused by C. albipunctata in Beni-Suef Governorate, the second in Egypt and third case worldwide. The study throws some light on the medical importance and manage­ment of urinary myiasis.

    2012-08-01

    Full Text Available Background: Over 60 Asian and European families with cortical myoclonic tremor and epilepsy have been reported under various names. Cerebellar changes may be part of the syndrome. In this study, we report the neuropathology findings in a new Dutch familial cortical myoclonic tremor with epilepsy case and review the literature on this syndrome.Methods: Neuropathological investigations were performed for a third case of the Dutch pedigree. In addition, we searched the literature for pedigrees meeting the criteria for benign familial myoclonic tremor and epilepsy.Results: Our third Dutch case showed cerebellar Purkinje cell changes and a normal cerebral cortex. The pedigrees described show phenotypical differences, cerebellar symptoms and cerebellar atrophy to a variable degree. Japanese pedigrees with linkage to chromosome 8q have been reported with milder disease features than members of Italian pedigrees with linkage to chromosome 2p. French pedigrees (5p possibly show even more severe and progressive disease, including cognitive changes and cerebellar features.Discussion: Currently, familial cortical myoclonic tremor is not listed by the International League Against Epilepsy, although it can be differentiated from other epileptic syndromes. Genetic heterogeneity and phenotypical differences between pedigrees exist. Cerebellar changes seem to be part of the syndrome in at least a number of pedigrees.

    Full Text Available Background: The natural history and etiology of malignant mesothelioma (MM is already thoroughly described in the literature, but there is still debate on prognostic factors, and details of asbestos exposure and possible context with clinical and demographic data, have not been investigated comprehensively. Objectives: Description of patients with MM, focusing on exposure, occupation, survival and prognostic factors. Methods: Review of medical records of patients with MM from 1984 to 2010 from a Danish Occupational clinic. Survival was estimated using Kaplan-Meier survival analysis and prognostic factors were identified by Cox regression analysis. Results: 110 (90.2% patients were male, and 12 (9.8% were female. The median (interquartile rang [IQR] age was 65 (13 years. Pleural MM was seen in 101 (82.8% patients, and peritoneal in 11 (9.0%; two (1.6% had MM to tunica vaginalis testis, and eight (6.6% to multiple serosal surfaces. We found 68 (55.7% epithelial tumors, 26 (21.3% biphasic, and 6 (4.9% sarcomatoid. 12 (9.8% patients received tri-modal therapy, 66 (54.1% received one-/two-modality treatment, and 36 (29.5% received palliative care. Asbestos exposure was confirmed in 107 (91.0% patients, probable in four (3.3%, and unidentifiable in 11 (9.0%. The median (IQR latency was 42 (12.5 years. Exposure predominantly occurred in shipyards. The median overall survival was 1.05 (95% CI: 0.96–1.39 years; 5-year survival was 5.0% (95% CI: 2.0%–13.0%. Female sex, good WHO performance status (PS, epithelial histology and tri-modal treatment were associated with a favorable prognosis. Conclusion: MM continuously presents a difficult task diagnostically and therapeutically, and challenges occupational physicians with regard to identification and characterization of asbestos exposure.

    2012-08-01

    Full Text Available Abstract Background Analysis is lacking on the management of vector control systems in disease-endemic countries with respect to the efficiency and sustainability of operations. Methods Three locations were selected, at the scale of province, municipality and barangay (i.e. village. Data on disease incidence, programme activities, and programme management were collected on-site through meetings and focus group discussions. Results Adaptation of disease control strategies to the epidemiological situation per barangay, through micro-stratification, brings gains in efficiency, but should be accompanied by further capacity building on local situational analysis for better selection and targeting of vector control interventions within the barangay. An integrated approach to vector control, aiming to improve the rational use of resources, was evident with a multi-disease strategy for detection and response, and by the use of combinations of vector control methods. Collaboration within the health sector was apparent from the involvement of barangay health workers, re-orientation of job descriptions and the creation of a disease surveillance unit. The engagement of barangay leaders and use of existing community structures helped mobilize local resources and voluntary services for vector control. In one location, local authorities and the community were involved in the planning, implementation and evaluation of malaria control, which triggered local programme ownership. Conclusions Strategies that contributed to an improved efficiency and sustainability of vector control operations were: micro-stratification, integration of vector control within the health sector, a multi-disease approach, involvement of local authorities, and empowerment of communities. Capacity building on situational analysis and vector surveillance should be addressed through national policy and guidelines.

  20. Open Coding Descriptions

    Directory of Open Access Journals (Sweden)

    Barney G. Glaser, PhD, Hon PhD

    2016-12-01

    Full Text Available Open coding is a big source of descriptions that must be managed and controlled when doing GT research. The goal of generating a GT is to generate an emergent set of concepts and their properties that fit and work with relevancy to be integrated into a theory. To achieve this goal, the researcher begins his research with open coding, that is coding all his data in every possible way. The consequence of this open coding is a multitude of descriptions for possible concepts that often do not fit in the emerging theory. Thus in this case the researcher ends up with many irrelevant descriptions for concepts that do not apply. To dwell on descriptions for inapplicable concepts ruins the GT theory as it starts. It is hard to stop. Confusion easily sets in. Switching the study to a QDA is a simple rescue. Rigorous focusing on emerging concepts is vital before being lost in open coding descriptions. It is important, no matter how interesting the description may become. Once a core is possible, selective coding can start which will help control against being lost in multiple descriptions.

    Progressive vaccinia (PV) is a rare but potentially lethal complication that develops in smallpox vaccine recipients with severely impaired cellular immunity. We describe a patient with PV who required treatment with vaccinia immune globulin and who received 2 investigational agents, ST-246 and CMX001. We describe the various molecular, pharmacokinetic, and immunologic studies that provided guidance to escalate and then successfully discontinue therapy. Despite development of resistance to ST-246 during treatment, the patient had resolution of PV. This case demonstrates the need for continued development of novel anti-orthopoxvirus pharmaceuticals and the importance of both intensive and timely clinical and laboratory support in management of PV.

    Full Text Available This report describes a rare case of nodular fasciitis (NF of the oral cavity, discussing the clinical, histological, and immunohistochemical characteristics. Histopathologic diagnosis of this type of lesion can be challenging due to its differential diagnosis, which principally includes sarcoma. The patient presented with a painless, well-defined nodule, reported as increasing in size, located at the apical aspect of the upper left buccal sulcus. Histologically, the lesion revealed spindle cell proliferation arranged in fascicles, while immunohistochemistry demonstrated positivity for smooth muscle actin. Eight months after complete surgical excision, no signs of local recurrence have been observed.

Patients and methods: A retrospective descriptive epidemiological analysis of all ovarian cancer cases recorded in the Saudi Cancer Registry (SCR from January 2001–December 2008 was performed. The data were analyzed using descriptive statistics, analysis of variance tests, Poisson regression, and simple linear modeling.Results: A total of 991 ovarian cancer cases were recorded in the SCR from January 2001–December 2008. The region of Riyadh had the highest overall ASIR at 3.3 cases per 100,000 women, followed by the Jouf and Asir regions at 3.13 and 2.96 cases per 100,000 women. However, Hail and Jazan had the lowest rates at 1.4 and 0.6 cases per 100,000 women, respectively. Compared to Jazan, the incidence rate ratio for the number of ovarian cancer cases was significantly higher (P<0.001 in the Makkah region at 6.4 (95% confidence interval [CI]: 4.13–9.83, followed by Riyadh at 6.3 (95% CI: 4.10–9.82, and the eastern region of Saudi Arabia at 4.52 (95% CI: 2.93–6.98.

    This case describes the outcomes of a multifaceted rehabilitation program including body weight-supported overground gait training (BWSOGT) in a nonambulatory child with cerebral palsy (CP) and the impact of this treatment on the child's functional mobility. The patient is a nonambulatory 10-year-old female with CP who during an inpatient rehabilitation stay participated in direct, physical therapy 6 days per week for 5 weeks. Physical therapy interventions included stretching of her bilateral lower extremities, transfer training, bed mobility training, balance training, kinesiotaping, supported standing in a prone stander, two trials of partial weight-supported treadmill training, and for 4 weeks, three to five times per week, engaged in 30 minutes of BWSOGT using the Up n' go gait trainer, Lite Gait Walkable, and Rifton Pacer gait trainer. Following the multifaceted rehabilitation program, the patient demonstrated increased step initiation, increased weight bearing through bilateral lower extremities, improved bed mobility, and increased participation in transfers. The child's Gross Motor Functional Measure (GMFM) scores increased across four dimensions and her Physical Abilities and Mobility Scale (PAMS) increased significantly. This case report illustrates that a multifaceted rehabilitation program including BWSOGT was an effective intervention strategy to improve functional mobility in this nonambulatory child with CP.

    Full Text Available Abstract Background Technological advances have enabled the widespread use of video cases via web-streaming and online download as an educational medium. The use of real subjects to demonstrate acute pathology should aid the education of health care professionals. However, the methodology by which this effect may be tested is not clear. Methods We undertook a literature review of major databases, found relevant articles relevant to using patient video cases as educational interventions, extracted the methodologies used and assessed these methods for internal and construct validity. Results A review of 2532 abstracts revealed 23 studies meeting the inclusion criteria and a final review of 18 of relevance. Medical students were the most commonly studied group (10 articles with a spread of learner satisfaction, knowledge and behaviour tested. Only two of the studies fulfilled defined criteria on achieving internal and construct validity. The heterogeneity of articles meant it was not possible to perform any meta-analysis. Conclusions Previous studies have not well classified which facet of training or educational outcome the study is aiming to explore and had poor internal and construct validity. Future research should aim to validate a particular outcome measure, preferably by reproducing previous work rather than adopting new methods. In particular cognitive processing enhancement, demonstrated in a number of the medical student studies, should be tested at a postgraduate level.

  6. Spontaneous nervous system concussion in dogs: a description of two cases and a review of terminology in veterinary medicine

    Directory of Open Access Journals (Sweden)

    Angelo Pasquale Giannuzzi

    2017-11-01

    Full Text Available In human medicine, central nervous system (CNS concussion is defined as a transient neurological dysfunction following a traumatic event, without evidence of structural abnormalities of the affected region on advanced diagnostic imaging. Depending on the anatomical region involved, three forms of concussive syndromes are described: brain concussion, spinal concussion and cerebellar concussion. Although major textbooks of veterinary neurology admit the existence of canine brain concussion, spontaneous cases of this pathological condition have not been reported in small animals so far. This report describes two cases of concussion in dogs: a 9-month-old, intact male, shih-tzu with brain concussion; and a 10-month-old, intact male, poodle with cerebellar concussion. In addition, a brief review of the definition of the term “concussion” in the veterinary medical literature is provided, in comparison to its meaning in the human medical literature. Finally, this paper proposes an appropriate definition of “concussion” in dogs, that may facilitate clinicians in the recognition of such an elusive syndrome.

    There are few epidemiological data available on rare skin cancer, including Kaposi's sarcoma (KS), which is a multifocal illness affecting the skin, mucosa, and viscera. Four different types of KS have been described: classic, AIDS-associated, iatrogenic, and African. The purpose of this study was to describe the epidemiology and evolution of the different types of KS in the Doubs region of France. A retrospective population-based study was conducted, including 57 patients with KS from the Doubs region between 1977 and 2009. These patients were identified by the tumor registry of the Doubs region. A larger proportion of AIDS-associated KS (61%) was observed compared to classic KS (30%) and iatrogenic KS (9%). No cases of African KS were observed. Most new cases were observed between 1987 and 1996 due to the AIDS explosion. The patients were predominantly male, with a male/female ratio at 10 : 4 (34 for AIDS-associated KS). The mean age of patients was 50.2 (higher in classic and iatrogenic KS and lower in AIDS-associated KS). Mucosal and visceral forms were more common in AIDS-associated KS, explaining the higher rate of mortality due to KS (21%). KS, which used to be a rare illness, as it existed only in the classic form, has become more common since the appearance of HIV and, to a lesser extent, of immunosuppressive treatment. © 2014 The International Society of Dermatology.

    A case-control study on lung cancer and radon exposure in dwellings has been carried out in Lazio, a high indoor radon region of Central Italy. A total of about 400 cases and 400 controls were recruited and radon concentration was measured in a total of about 1850 dwellings. In each dwelling, radon concentration measurement devices were placed in both the main bedroom and living room for two consecutive six-month periods. Each radon device, enclosed in a sealed polyethylene bag, contains two LR 115 detectors, each being covered by a thin absorber to reduce the alpha-energy within the detector sensitive range. A quality assurance program, described in this paper, was applied in order to reduce radon concentration measurement uncertainty, which have a significant impact on the results of an epidemiological study. The reported internal quality control and intercomparison results are compared with the results of other studies, and show that the radon measurement precision and accuracy obtained in this study can be considered quite good.

  9. Emotion-focused therapy for the treatment of social anxiety: an overview of the model and a case description.

    Science.gov (United States)

    Shahar, Ben

    2014-01-01

    Emotion-focused therapy (EFT) is an integrative and experiential treatment approach that views emotions as fundamentally adaptive and privileges attention to, and exploration of, emotional experiences. EFT has been demonstrated to be efficacious with depression, interpersonal trauma and marital discord, but application to anxiety disorders is in its initial stages. The purpose of this paper is to present the main principles of using EFT with socially anxious patients and to make the case that EFT is particularly well suited for working with this patient group. The primary change processes in EFT for social anxiety include improving emotion awareness, reducing experiential avoidance and the activation and transformation of shame that underlies the symptomatic anxiety. Such processes lead to less self-criticism, to more self-compassion and self-soothing and to a more favourable perception of the self. A case example is used to illustrate how these principles were applied with a socially anxious patient. Copyright © 2013 John Wiley & Sons, Ltd.

    Mycetoma is a chronic suppurative and/or granulomatous inflammatory lesion of skin, subcutaneous tissue, fascia, and tendons caused by the traumatic inoculation of either fungal (eumycotic) or bacterial (actinomycotic) organisms present in the soil. The disease is characterized by triad of tumefaction, discharging sinuses, and grains. Thirteen new cases of biopsy proven mycetomas were analyzed, retrospectively, from January 2000 to October 2009. Clinical parameters, bone involvement, microbiological properties, and histopathological features were evaluated. Categorization into eumycotic or actinomycotic was based upon features on hematoxylin and eosin stained sections with special stains. Therapeutic outcome was presented wherever available. There were eight actinomycetomas and five eumycetoma cases including 11 men and two women. Foot and lower extremities were the most common site of involvement (9 of 13, 69%). Culture results were available in 8 of 13 cases (61.5%). Madurella mycetomatis, Neoscytalidium dimidiatum, and Aspergillus flavus were the isolates among eumycetomas whereas Acinomadura madurae, Actinomadura pelletieri, and Nocardia species were the isolates among actinomycetomas. Two cases had underlying bone involvement. On follow-up, four of five eumycetoma cases showed partial improvement following surgery and antifungal therapy, one had amputation of the lower leg. Of the actinomycetomas, six of eight had dramatic improvement following sulfamethoxazole-trimethoprim based therapy, one had complete cure, and one was lost to follow-up. Strong clinical suspicion, exact categorization of lesion into eumycotic or actinomycotic along with culture correlation, is essential for prognosis and effective therapy. © 2010 The International Society of Dermatology.

    Clavicle fractures correspond to 35% of traumatic fractures of the shoulder girdle. Regional anaesthesia has shown better analgesic results than systemic treatment for perioperative management. Innervation of the clavicle is complex, at present its knowledge raises controversy. The lateral pectoral nerve through the innervating musculature predominantly participates in the lateral and anterior part of the clavicle. The following report of 7 cases describes the effective postoperative analgesia of modified PEC II block in patients with middle third clavicle fracture or acromioclavicular dislocation who underwent a modified PEC II block for postoperative pain management, in the context of a multimodal analgesia. The potential advantage of this management over other analgesic procedures should be evaluated in specific clinical trials.

  12. Description of survival data extended to the case of competing risks: a teaching approach based on frequency tables

    Full Text Available Survival analysis is a powerful statistical tool to study failure-time data. In introductory courses students learn how to describe right-censored survival time data using the product-limit estimator of the survival function on a given end-point relying on a product of conditional survival probabilities. In the case of a composite end-point, the next step is to account for the presence of competing risks. The complement to one of the survival function is decomposed into the sum of cause-specific incidences, which are obtained as sum of unconditional probabilities due to the single competing risk. However, this algebraic decomposition is not straightforward, given the difference between the structure of the involved estimators. In addition, one is tempted to use the Kaplan-Meier estimator, leading to an erroneous decomposition of the overall incidence. Here we discuss a simple reinterpretation of the Kaplan-Meier formula in terms of sum of non-conditional probabilities of developing the end-point in time, adjusted for the presence of censoring. This approach could be used for describing survival data through simple frequency tables which are directly generalized to the case of competing risks. In addition, it makes clear how the estimation of the single cause-specific incidence through the Kaplan-Meier estimator, simply considering the occurrence of competing events as censored data, leads to an overestimation of the cause-specific incidence. Two examples are provided to support the explanation: the first one, could help to clarify the procedure described by the formulas; the second one, simulates real data in order to present graphically the results.

    The use of elastomeric devices for ambulatory intravenous pain treatment in Major Ambulatory Surgery (MAS) has been described to improve postoperative pain management. The objective of the study was to describe the first 3 years experience of the use of elastomeric devices for ambulatory intravenous pain treatment in MAS implemented at our site since 2010. Data were retrieved from the medical records for all patients who, between January 2010 and March 2014, underwent surgical procedures at the ambulatory surgical centre at our hospital and were prescribed a home-based continuous intravenous analgesia. Data were retrieved from the medical records of 1128 patients. The most frequent surgical interventions included orthopedic and proctology surgeries. 80 % of patients were discharged home without pain; during the first 48 h after discharge roughly 40 % of subjects were completely free of pain, 50 % reported mild pain (VAS 1 to 3) and 9 % reported higher pain scores (4 and above). Peripheral nerve block was associated to better pain control in the immediate postoperative period. Vomiting in the first 24 h was 4.6 % before introducing haloperidol into the drug schemes, and 2.6 % thereafter. Complications related with the intravenous route required treatment withdrawal in 1.1 % cases. Only 3.5 % of patients returned to the hospital in the first 72 h, mainly for non-pain related reasons. Overall, 99.5 % of patients were satisfied with the treatment received at home. Our initial experience suggest that outpatient multimodal intravenous analgesia in patients undergoing day-case surgery is a feasible alternative in our setting, that allows an effective management of postoperative pain with a small rate of adverse events and complications requiring readmission.

    Diagnosis of HIV infection during early stages is mandatory to catch up with the challenge of limiting HIV viral replication and reservoirs formation, as well as decreasing HIV transmissions by immediate cART initiation. Aims were to describe (a) virological characteristics of AHI identified, (b) epidemiological and clinical factors associated with being diagnosed with AHI. Cross-sectional, retrospective study. All individuals diagnosed with AHI according to Fiebig's staging between Jan 2013 and Mar 2014 at the INMI "L. Spallanzani" were included. Serum samples reactive to a fourth generation HIV-1/2 assay (Architect HIV Ag/Ab Combo, Abbott) were retested with another fourth generation assay (VIDAS DUO HIV Ultra, Biomérieux) and underwent confirmation with HIV-1 WB (New Lav I Bio-Rad) and/or with Geenius confirmatory assay (Bio-Rad). WHO criteria (two env products reactivity) were used to establish positivity of confirmatory assays. In case of clinically suspected AHI, HIV-1 RNA (Real time, Abbott) and p24 assay (VIDAS HIV P24 Bio-Rad) were also performed. Avidity test was carried out, on confirmed positive samples lacking p31 reactivity, to discriminate between recent (true Fiebig V phase) and late infections; to avoid possible misclassifications, clinical data were also used. Demographic, epidemiological, clinical and laboratory data are routinely, and anonymously recorded in the SENDIH and SIREA studies. During the study period, we observed 483 newly HIV diagnosed individuals, of whom 40 were identified as AHI (8.3%). Fiebig classification showed: 7 stage II/III, 13 stage IV, 20 stage V. Demographic, epidemiological, and clinical characteristics of patients are shown in the Table. Overall, the study population had a median S/Co ratio at fourth generation EIA (Architect) of 49.50 (IQR, 23.54-98.05): values were significantly lower in Fiebig II-IV than in Fiebig V (38.68 [IQR, 20.08-54.84] vs 75.72 [IQR, 42.66-249.80], p=0.01).

    Prostate cancer is one of the most common cancers which develops by mutations and/or other genetic alterations in specific genes. Regarding the previous studies in literature predominant mutations take place in KRAS, BRAF, and EGFR genes in special types of cancers. In this research, we attempt to identify the prevalence and significant role of the possible mutations in EGFR exons 18-21, KRAS codon 12, 13, and 61, and BRAF codon 600 mutations in tumoral tissue specimens from patients with prostatic adenocarcinoma. Furthermore, in this research, it has been attempted to investigate the molecular characteristics of these genes in terms of bioinformatic aspects. A total of 35 prostatic adenocarcinoma fresh tissue samples, enriched in neoplastic cells, were obtained from the Cancer Institute of Iran. The presence of mutations at codons 12, 13 and 61 of KRAS, codon 600 of BRAF and EGFR exons 18-21 were determined by direct Sanger sequencing. To evaluate the molecular features, structure, and post-translation modification of those genes, a bioinformatics survey was performed using the SWISS-MODEL (http://swissmodel.expasy.org) and NetPhos 2.0 (http://www.cbs.dtu.dk/services/NetPhos/) Server. Also, using bioinformatics software, the phylogeny tree of the mutations was drawn. Mutations of codons 12 and 13 of KRAS were found in 2 of the 35 prostatic adenocarcinomas. Two cases carried homozygous mutations on exon 2 in codon 12 (G12V) and codon 13 (G13D). Also, no mutation was detected at BRAF codon 600 and EGFR exons 18-21 in any of the samples. Based on the group of patients with prostate adenocarcinoma, our research shows that the mutations in codons 12 and 13 of KRAS are the most common in prostate carcinomas. Noting these results and the molecular pathway of this gene, there is a possible more perceptible role for this gene in the pathogenesis of prostatic carcinoma. However, according to our finding, as in previous studies, the role of BRAF and EGFR gene mutations in

    Full Text Available Abstract Aim To describe the development of a dementia research registry, outlining the conceptual, practical and ethical challenges, and to report initial experiences of recruiting people with dementia to it from primary and secondary care. Background Women, the oldest old and ethnic minorities have been under-represented in clinical trials in dementia. Such under-representation biases estimates of absolute effect, absolute harm and cost-effectiveness. Research on dementia should include patient populations that more exactly reflect the population at risk. One of the impediments to this is the lack of a suitable tool for identification of patients suitable for studies. Construction & contents A technology development methodology was used to develop a registry of people with dementia and their carers. This involved phases of modelling and prototype creation, 'bench testing' the prototype with experts and then 'field testing' the refined prototype in exemplar sites. The evaluation of the field testing described here is based on a case study methodology. Utility This case study suggests that construction and population of a dementia research registry is feasible, but initial development is complex because of the ethical and organisational difficulties. Recruitment from primary care is particularly costly in terms of staff time and only identifies a very small number of people with dementia who were not already known to specialist services. Recruiting people with dementia through secondary care is a resource intensive process that takes up to six months to complete. Identifying the components of a minimum dataset was easy but its usefulness for pre-screening potential research populations has yet to be established. Acceptance rates are very high in the first clinic to recruit to the registry, but this may reflect the efforts of registry 'champions'. Discussion and Conclusions Easier recruitment may perpetuate potential selection biases and we are

    Full Text Available This report presents a case of two smooth muscle hamartomas of the stomach in a 10-year-old male Boxer. The clinical history of the animal was of chronic vomiting, weight loss, and intermittent gastric distension, and it died because of chronic and congestive heart failure. Gross, histology, and immunohistochemistry (IHC exams were performed. On necropsy, in the pyloric region of the stomach, two closely related polypoid growths between 10 and 15 mm in diameter were identified. On the cut sections, both polyps presented white to gray color, with homogenous architecture and well-defined limits. The thickness of the submucosal layer was seen to be increased to 1 cm. No other gastric alterations were identified by the necropsy exam. Histologically, both masses growth consisted of hyperplastic glands lined by foveolar epithelium, arranged in a papillary or branching pattern, and supported by a core of well-vascularised and marked smooth muscle tissue interspersed between glands. No dysplastic cells and mitotic figures were observed in these lesions. Immunohistochemistry revealed a strong cytoplasm labelling for smooth muscle actin of the bundles around the mucosal glands. To our knowledge, this is the first report of smooth muscle hamartomas mimicking multiple gastric polyps in dogs.

    Intrathecal injection of fluorescein is a method for repairing cerebrospinal fluid fistulas. The most frequent surgical procedure is endonasal endoscopy and the purpose of injecting this dye is to locate the fistula. The anaesthesiologists usually perform the puncture, therefore it is necessary to review this method and to specify some anaesthetic considerations such as correct dosing, safe management protocols and medical-legal aspects. In this case-report we describe the pre, intra and postoperative protocol of action implemented in our department that basically consists of: obtaining a specific consent, prior neurological/ophthalmologic assessment to rule out hypertension and brain damage, use of corticosteroids and previous antihistamines, choosing the correct dose and concentration of intrathecal sodium fluorescein (maximum 1ml at a concentration of 5% diluted in 9ml of cerebrospinal fluid) and close intra and postoperative monitoring.

    Full Text Available Visceral leishmaniasis is an infectious disease of chronic, emerging and zoonotic nature that presents various degrees of severity. In Brazil, this illness is caused by Leishmania infantum (Leishmania chagasi, which is transmitted by the bite of the sand fly Lutzomyia longipalpis, and dogs are its main reservoir. Given the increasing spread of this disease across Brazil, the aim of this study was to report on six cases of canine visceral leishmaniasis, diagnosed in June 2013, in the city of Pedregulho, State of São Paulo, considered to be a non-endemic area and free of phlebotomine sand flies. The diagnosis was based on clinical signs of the patients and additional tests (serological and parasitological. It was concluded that the diagnosis of leishmaniasis is complex because the clinical signs are similar to other systemic diseases, thus justifying the importance of parasitological test of bone marrow, considered "gold standard", in the confirmation of the disease. In addition, the area was not, until now, considered risk place, despite notification.

    Malaria is a major public health problem and still reported among the 10 top causes of morbidity and mortality in Ethiopia. More than one-third of the people sought treatment from the private health sector. Evaluating adherences of health care providers to standards are paramount importance to determine the quality and the effectiveness of service delivery. Therefore, the aim of this study was to evaluate the contribution of public private mix (PPM) approach in improving quality of malaria case management among formal private providers. A retrospective data analysis was conducted using 2959 facility-months data collected from 110 PPM for malaria care facilities located in Amhara, Dire Dawa, Hareri, Oromia, Southern Nation Nationalities and Peoples and Tigray regions. Data abstraction formats were used to collect and collate the data on quarterly bases. The data were manually cleaned and analysed using Microsoft Office Excel 2010. To claim statistical significance non-parametric McNemar test was done and decision accepted at P management using chloroquine (CQ) was improved from 44.1 % in the first quarter to 98.12 % in the last quarter (X(2) = 11.62, P management practice of health care providers at the formal private health facilities. Therefore, regional health bureaus and partners shall closely work to scale up the initiated PPM for malaria care service.

    Full Text Available Two young dogs were presented for the evaluation of an abnormally haired appearance of both eyes since adoption. In one dog, the lesions were symmetrical and appeared as disorganized skin tissue located on the cutaneous aspect of the lateral portion of both lower eyelids, and continuing to the palpebral and the bulbar conjunctiva, thus forming continuous lesions. In the other dog, a similar lesion was present in the right eye (OD, but the lesion of the left eye (OS was of discontinuous, disorganized skin tissue located midway on the lower eyelid and on the lateral bulbar conjunctiva. The lesions were surgically removed and routinely processed for histopathological analysis. Definitive diagnosis was conjunctivo-palpebral dermoids for each dog. Dermoids are usually considered to be choristoma (normal tissue in an abnormal location when they are located on the ocular surface (cornea and/or conjunctiva and as hamartoma when located on the palpebral skin. The lesion presentation in these two dogs reveals that names of “choristoma” alone or “hamartoma” alone are not accurate to depict the continuous, composite, conjunctivo-palpebral dermoids. These cases suggest that choristoma and hamartoma might develop subsequently from the same abnormal event during the embryonic development, which means that the lesion location might be the only difference between the two terms.

    Full Text Available Bowel stent insertion has a variety of complications one major of which is colonic perforation. The purpose of this article is to reveal two cases with delayed colonic perforation after stent placement to relieve bowel obstruction caused by rectal cancer. The first patient was a 55 year-old man who was a candidate for stent placement to avoid palliative surgery and relieve his bowel obstruction. Although the procedure resulted in complete relief of patient symptoms, but he returned with signs of peritonitis 10 days after the stent placement. A perforation was found at rectosigmoid junction on laparotomy. The second patient was a 60 year-old man who underwent a successful stent placement and returned 3 months later with a complaint of abdominal pain that showed up to be due to a rectal perforation on investigations. In conclusion, bowel perforation following stent placement can be a major complication, so close follow-up is necessary to detect it as soon as possible and prevent it from becoming an irreparable complication.

    Descriptive statistics is the branch of statistics that gives recommendations on how to summarize clearly and simply research data in tables, figures, charts, or graphs. Before performing a descriptive analysis it is paramount to summarize its goal or goals, and to identify the measurement scales of the different variables recorded in the study. Tables or charts aim to provide timely information on the results of an investigation. The graphs show trends and can be histograms, pie charts, "box and whiskers" plots, line graphs, or scatter plots. Images serve as examples to reinforce concepts or facts. The choice of a chart, graph, or image must be based on the study objectives. Usually it is not recommended to use more than seven in an article, also depending on its length.

    There are few epidemiological data available on rare skin cancer, including Merkel cell carcinoma, Paget's disease, adnexal carcinoma, and sarcoma. We conducted this study to investigate the epidemiology of rare skin cancer diagnosed in the department of Doubs from 1980 to 2004. Data were collected from a population-based cancer registry from 1980 to 2004. Diagnosis was based on the 3(rd) edition of the International Classification of Diseases for Oncology. The incidence rates were standardized on world population. One hundred and fifty one patients were investigated (88 women and 63 men). Median age for the diagnosed disease was 63 years. The standardized incidence rate was 0.82/100 000 person-year (95% CI = 0.68-0.96) and increased from 0.25 in 1980-1984 to 1.50 in 2000-2004. Fifty nine cases (39%) were sarcomas, 35 (23%) adnexal carcinomas, 27 (18%) Merkel cell carcinoma and 27 (18%) Paget's disease. The standardized incidence rates were 0.37/100 000 (0.27-0.47) for sarcomas, 0.16 (0.10-0.22) for adnexal tumors, 0.13 (0.08-0.18) for Merkel cell carcinoma, and 0.15 (0.09-0.21) for Paget's disease. Our results based on a population-based cancer registry showed an increase of the standardized incidence rate for all types of rare skin tumors. These results may be useful when considering the growing interest in rare diseases in identifying risk factors and planning scientific research programmes.

    Presentation of the difficulties in diagnosing Münchausen syndrome by proxy. Comparison of four different conclusions in forensic psychiatric opinions issued in one case, due to the need of answering to the questions of the court, in what periods and why was the deterioration of the child's health, in connection with an allegation that the mother has acted to his detriment. In the first medical-legal opinion the treating physician, while being the head of the ward and the person informing the police of the action against a child by the mother, recognised Münchausen syndrome by proxy. The second opinion was delivered by a psychologist, who stated that the mother distinguished the introspective attitude characterised by excessive, exaggerated accuracy, thoroughness, and did not give a unambiguous answer to the questions of the court. In the third opinion the experts accepted that the functioning of the subject does not create a threat to life and health of the child. The fourth opinion developed by the authors of this paper noted that in the analysed medical records of the childs' hospitalisation, no arguments were found to recognise Münchausen syndrome by proxy. RESULTS. In the conducted extended ambulant study of the subject and the analysis of the medical documentation of the 31 hospitalisations of the child showed that the improvement of the child's health was not associated in exclusion of pushing aside the mother from the child, but was the result of the consistency of the therapeutic treatment team, the continuation and the modification of the treatment. In appointing the expert, the art. 196 of the Code of Criminal Procedure should be considered, which states that the expert should not be the treating doctor, because his opinion loses value impartiality. Diagnosis of Münchausen Syndrome by proxy itself stirs up numerous controversies..

    Full Text Available Abstract Introduction Acute kidney injury in the setting of adult minimal change disease is associated with proteinuria, hypertension and hyperlipidemia but anemia is usually absent. Renal biopsies exhibit foot process effacement as well as tubular interstitial inflammation, acute tubular necrosis or intratubular obstruction. We recently managed a patient with unique clinical and pathological features of minimal change disease, who presented with severe anemia and acute kidney injury, an association not previously reported in the literature. Case presentation A 60-year-old Indian-American woman with a history of hypertension and diabetes mellitus for 10 years presented with progressive oliguria over 2 days. Laboratory data revealed severe hyperkalemia, azotemia, heavy proteinuria and progressively worsening anemia. Urine eosinophils were not seen. Emergent hemodialysis, erythropoietin and blood transfusion were initiated. Serologic tests for hepatitis B, hepatitis C, anti-nuclear antibodies, anti-glomerular basement membrane antibodies and anti-neutrophil cytoplasmic antibodies were negative. Complement levels (C3, C4 and CH50 were normal. Renal biopsy unexpectedly displayed 100% foot process effacement. A 24-hour urine collection detected 6.38 g of protein. Proteinuria and anemia resolved during six weeks of steroid therapy. Renal function recovered completely. No signs of relapse were observed at 8-month follow-up. Conclusion Adult minimal change disease should be considered when a patient presents with proteinuria and severe acute kidney injury even when accompanied by severe anemia. This report adds to a growing body of literature suggesting that in addition to steroid therapy, prompt initiation of erythropoietin therapy may facilitate full recovery of renal function in acute kidney injury.

    Full Text Available This article provides a case study on participatory assessment based on experience gained from an EU–Oxfam GB project entitled “Empowering Municipalities to Effectively Address Poverty” conducted in five small towns in Russia. Participatory assessment through focus group discussions (FGDs was the main approach used in the implementation of the project. A participatory assessment was performed through 25 FGDs in five remote areas in central Russia. More than 200 participants representing people living in poverty, such as single mothers, people with disabilities, families with many children, families with disabled children, and pensioners, voluntarily participated in the meetings. Most of the participants were women (75% aged between 25 and 70 years. We consider that the participants’ representation is relevant in accordance with the official poverty studies. Through identification of patterns of recurrent ideas and opinions, a qualitative method helps us understand social phenomena from the views of and on the basis of the opinions of the participants. The FGDs’ narratives underwent pattern analysis, resulting in the framing of the cluster themes and narrative conceptualization. Cluster analysis of the FGDs’ narratives led to the framing of 10 cluster themes of importance, followed by conceptual descriptions and related narratives. The conceptual description of the leading theme, feeling of despair (theme 1, was described by respondents’ expressions/narratives, such as “Nobody needs us and there is no future for us and our children in this town,” the narrative idea that crosscuts the subsequent themes. The following nine themes are of equal importance, are interlinked, and for the major part constitute the leading theme, feeling of despair (theme 1: state social and family support (theme 2; health care (theme 3; who are those living in poverty?

    Exercise-induced laryngeal obstruction (EILO), the condition previously known as paradoxical vocal fold motion and vocal cord dysfunction, is characterized by inappropriate glottic or supraglottic obstruction during high-intensity exercise, causing exertional dyspnea, frequently with stridor. EILO is definitively diagnosed through upper-airway visualization during a characteristic episode. Although respiratory retraining is a primary therapy for EILO, many patients report symptom persistence despite adequate performance of traditional techniques. This report describes three novel breathing techniques for EILO, the Olin EILOBI (EILO biphasic inspiratory) breathing techniques. We include a teaching process and case series with patient-reported assessments. Following descriptions of the techniques and teaching process, we present data from a questionnaire offered to all patients who learned at least one of the techniques between September 2015 and March 2017. Subjects evaluated (1) expectation setting, (2) teaching processes, (3) their ability to implement the techniques during high-intensity exercise, and (4) perceived clinical effectiveness. Ninety-five percent of eligible patients participated, a primarily young, female, and Caucasian sample. Over 50% of subjects competed at the high school varsity level. Sixty-two percent of subjects perceived reasonable expectations, and 82% positively evaluated the teaching process. Seventy-nine percent were able to employ their technique in the high-intensity activity of choice, and 66% perceived clinical effectiveness with the techniques. The Olin EILOBI breathing techniques are novel respiratory retraining techniques for use in high-intensity exercise. Case series subjects reported reasonable expectations, a helpful teaching process, the ability to use these techniques during high-intensity exercise, and perceived clinical effectiveness.

    Full Text Available Autosomal recessive  peripheral neuropathy with neuromyotonia  (ARAN-NM  is a relatively newly described  disease associated  with mutations  in the HINT1 gene.  It accounts  for a significant  part of the poorly  differentiated  forms  of axonal polyneuropathies.  We present the first in Russia description of the genetically confirmed case of ARAN-NM in a boy aged 14 years and 11 months without the hereditary-tainted anamnesis. On presentation,  the patient experienced  progressive  distal muscular weakness, asymmetric foot deformity,  gait disorders  and minimal manifestations  of neuromyotonia  (stiffness  in the fingers.  During examination,  we detected an increase in the level of creatine phosphokinase up to 635 U/l, a disturbance of conduction of motor and, to a lesser extent, sensory fibers  of  the  peripheral  nerves  (according  to  the  stimulation  electromyography,  EMG,  denervation-reinnervation  changes,  single positive acute waves, fibrillation potentials, complex repeated discharge (according to the data of needle EMG. In the study of exome, a homozygous mutation c.110G>C, p.R37P was determined in exon 01 of the HINT1 gene, which confirmed the presence of ARAN-NM. A molecular-genetic  examination of the patient's immediate relatives was carried out. The described case is compared with literature data. An overview of currently available information on ARAN-NM is provided. Diagnostic criteria of the disease are presented.

    Background: Unlike Western countries where asbestosis and erionite exposure is industrial, domestic exposure of these chriystals is common in central and eastern Turkey where they are used as a constrcution material for houses. This life-long exposure to these materials has been showed to be causing endemies of mesothelioma at younger ages in central Turkey. In this study it was aimed to assess the descriptive features of malignant mesothelioma cases and evaluate the domestic exposure of asbestosis and erionite. Method: Data were obtained through retrospective reviewing of the patient files of a pulmonary disease hospital in Ankara. Demographical features such as age, gender, the place of birth, migration and living, age of diagnosis and some clinical features were evaluated. Results: A total of 44 files of patients diagnosed with malignant mesothelioma were screened. The female to male ratio was 19/25. Of the patients 43 (97 %) were born in asbestosis-rich and only one (3 %)was born in erionite-rich region. All of the patients had resided in asbestosis-rich regions where they were born and the places where some of the patients moved were known to be rich for asbestosis as well. The age of diagnosis was between 32 and 78 years and the median age of diagnosis was 54,5 years. Family history of malignancy was negative in 39 patients (88.6%) and was positive in 5 patients (11.4%). History for smoking was 40.9%. The 81.1 % of the patients applied with the complaint of dispnea; 48.8 % with cough and 45.5 % with chest pain. Median time period between the date of disease onset and diagnosis was 91 days. The most rapid diagnosis was made as early as 28 days. Pleural fluid was seen in 95.5 % while pleural thickening was seen in 29,5 % of the patients. Respiratory funcitons were found to be deteriorated in 86.4 %. The histological types of epitheloid and mixt mesothelioma were seen with the percentages of 69 % and 31 % respectively. Conclusion: This was a descriptive study

  15. The application of bifrontal electrotherapy in patients with a diagnosis of schizophrenia – case series description

    Directory of Open Access Journals (Sweden)

    Karina Nowakowska

    2017-09-01

    Full Text Available Electrotherapy is considered a very effective and safe therapeutic method. Its most frequently described adverse effect is the impairment of cognitive functions. Currently, the most commonly applied form of electrotherapy are bitemporal procedures and the most frequent and best-studied indication for its application are depressive disorders. A method combining high effectiveness with satisfactory safety is the bifrontal application of the electrodes, although study results are often inconsistent. An issue which should also be noted is the lack of studies comparing the effectiveness of bifrontal and bitemporal procedures in the reduction of positive and negative symptoms of schizophrenia and assessing the safety of these methods in terms of the influence on cognitive functions. The present paper presents a clinical description of four patients with schizophrenia who have undergone electrotherapy procedures performed applying the bifrontal method. The decisive indication for applying the bifrontal procedures were the memory disturbances the persistence of which was reported by the patients during the application of bitemporal procedures. The analysed clinical cases indicate the effectiveness of the bifrontal electrotherapy procedures which was comparable with the effectiveness of bitemporal procedures with the simultaneous better toleration of the former. Improvement was observed in terms of paranoid, catatonic and negative schizophrenia symptoms. At the same time the patients reported subjectively better tolerance of the procedures, as well as improvement in the recalling of facts and events.

  16. Using seemingly unnecessary illustrations to improve the diagnostic usefulness of descriptions in taxonomy–a case study on Perochaeta orientalis (Diptera, Sepsidae

    Directory of Open Access Journals (Sweden)

    2013-11-01

    Full Text Available Many species descriptions, especially older ones, consist mostly of text and have few illustrations. Only the most conspicuous morphological features needed for species diagnosis and delimitation at the time of description are illustrated. Such descriptions can quickly become inadequate when new species or characters are discovered. We propose that descriptions should become more data-rich by presenting a large amount of images and illustrations to cover as much morphology as possible; these descriptions are more likely to remain adequate over time because their large amounts of visual data could capture character systems that may become important in the future. Such an approach can now be quickly and easily achieved given that high-quality digital photography is readily available. Here, we re-describe the sepsid fly Perochaeta orientalis (de Meijere 1913 (Diptera, Sepsidae which has suffered from inadequate descriptions in the past, and use photomicrography, scanning electron microscopy and videography to document its external morphology and mating behaviour. All images and videos are embedded within the electronic publication. We discuss briefly benefits and problems with our approach.

    Research into social root-causes of poor health within segregated Roma communities in Central and Eastern Europe, i.e. research into how, why and by whom high health-endangering settings and exposures are maintained here, is lacking. The aim of this study was to assess the local setup of health-endangering everyday settings and practices over the long-term in one such community. It is the initial part of a larger longitudinal study qualitatively exploring the social root-causes of poor Roma health status through the case of a particular settlement in Slovakia. The study, spanning 10 years, comprised four methodologically distinct phases combining ethnography and applied medical-anthropological surveying. The acquired data consisted of field notes on participant observations and records of elicitations focusing on both the setup and the social root-causes of local everyday health-endangering settings and practices. To create the here-presented descriptive summary of the local setup, we performed a qualitative content analysis based on the latest World Health Organization classification of health exposures. Across all the examined dimensions - material circumstances, psychosocial factors, health-related behaviours, social cohesion and healthcare utilization - all the settlements' residents faced a wide range of health-endangering settings and practices. How the residents engaged in some of these exposures and how these exposures affected residents' health varied according to local social stratifications. Most of the patterns described prevailed over the 10-year period. Some local health-endangering settings and practices were praised by most inhabitants using racialized ethnic terms constructed in contrast or in direct opposition to alleged non-Roma norms and ways. Our summary provides a comprehensive and conveniently structured basis for grounded thinking about the intermediary social determinants of health within segregated Roma communities in Slovakia and beyond

    Stratified mucin-producing intraepithelial lesion (SMILE) is a cervical intraepithelial lesion, distinct from conventional squamous or glandular counterparts, believed to arise from embryonic cells at the transformation zone by transdifferentiation during high-risk HPV-associated carcinogenesis. It is characterized by stratified, immature epithelial cells displaying varying quantities of intracytoplasmic mucin throughout the majority of the lesional epithelium. We identified a distinct form of invasive cervical carcinoma with morphologic features identical to those in SMILE, which we have termed "invasive stratified mucin-producing carcinoma." Fifteen cases from 15 patients (mean 36 y; range, 22 to 64 y) were retrieved from the pathology archives of multiple institutions with a diagnosis of either SMILE or invasive cervical carcinoma with a description or comment about the invasive tumor's resemblance to SMILE. Seven cases had solely intraepithelial disease with a component of SMILE (mean 29 y; range, 22 to 40 y). The 8 other cases had invasive stratified mucin-producing carcinoma (mean 44; range, 34 to 64 y) in which SMILE was identified in 7. All cases of invasive stratified mucin-producing carcinoma demonstrated stratified, immature nuclei with intracytoplasmic mucin, which morphologically varied between cases from "mucin-rich" to "mucin-poor" in a similar manner to SMILE. All cases had mitotic figures and apoptotic debris, and an intralesional neutrophilic infiltrate was seen in the majority of cases. In cases of invasive carcinoma, the depth of invasion ranged from <1 to 19 mm. Follow-up information was available in 8 cases and ranged from 1 to 36 months (mean 11 mo). Three cases of invasive stratified mucin-producing carcinoma had biopsy or resection-proven metastatic carcinoma on follow-up. These 15 cases of cervical stratified mucin-producing lesions show a combination of intraepithelial and invasive growth patterns. Given that SMILE is well rooted as a

    Following of the emergence of Zika virus in Brazil in 2015, an epidemiological surveillance system was quickly implemented in the French overseas Territories of America (FTA) according to previous experience with dengue and chikungunya and has detected first cases of Zika. General practitioners and medical microbiologists were invited to report all clinically suspected cases of Zika, laboratory investigations were systematically conducted (RT-PCR). On 18 December, the first autochthonous case of Zika virus infection was confirmed by RT-PCR on French Guiana and Martinique, indicating introduction of Zika virus in FTA. The viral circulation of Zika virus was then also confirmed on Guadeloupe and Saint-Martin. We report here early findings on 203 confirmed cases of Zika virus infection identified by RT-PCR or seroneutralisation on Martinique Island between 24 November 2015 and 20 January 2016. All cases were investigated. Common clinical signs were observed (maculopapular rash, arthralgia, fever, myalgia and conjunctival hyperaemia) among these patients, but the rash, the foundation of our case definition, may be absent in a significant proportion of patients (16%). These results are important for the implementation of a suspected case definition, the main tool for epidemiological surveillance, in territories that may be affected by ZIKV emergence, including Europe.

    Kamps, Oliver; Wilczek, Michael

    In this article we review two different approaches to the statistical description of turbulent flows in terms of evolution equations for probability density functions (PDFs), namely a description of the turbulent cascade by a Fokker- Planck equation, as well as kinetic equations in terms of the theoretical framework of the Lundgren-Monin-Novikov hierarchy. In both cases conditional averages are the building blocks that allow to make a connection to experimental or numerical data. Professor Dr. Rudolf Friedrich made central contributions to both of these approaches, which we want to highlight here.

    The aim of this research was to describe the cases of TNF-α antagonist-related alopecia reported in the French Pharmacovigilance Database (FPVD) and to investigate the association between exposure to TNF-α antagonists and occurrence of alopecia. All spontaneous reports of TNF-α antagonist-related alopecia recorded in the FPVD between January 2000 and April 2012 were colligated and described. We conducted disproportionality analyses (case/non-case method) to assess the link between the occurrence of alopecia and exposure to TNF-α antagonists. Cases were all reports of alopecia and non-cases were all other reports recorded during the study period. Exposure to TNF-α antagonists was sought in cases and in non-cases. Reporting odds ratios (RORs) were calculated to assess the association. Docetaxel was used as positive control and acetaminophen as negative control. We performed sensitivity analyses excluding cases of androgenic alopecia and those occurring in psoriatic patients. Among 282 590 spontaneous reports of adverse drug reactions (ADRs) collated in the FPVD, 1068 cases (alopecia reports) were identified. Of these cases, 52 (4.9%) occurred during exposure to TNF-α antagonists (18 involved infliximab, 17 adalimumab, 15 etanercept and 2 certolizumab). Exposure to TNF-α antagonists was more frequent among alopecia reports than among other ADR reports for all TNF-α antagonists pooled (ROR 3.0, 95% CI 2.3, 4.0) as well as for each antagonist separately, with similar values. Sensitivity analyses yielded similar results. The RORs were 29.9 (95% CI 25.3, 35.5) with docetaxel and 0.3 (95% CI 0.2, 0.4) with acetaminophen. The present study confirms a strong link between TNF-α antagonist exposure (class effect) and the occurrence of alopecia. © The Author 2014.

    Clinical characteristics might be associated with temporomandibular disorders (TMD) because they are antecedent risk factors that increase the likelihood of a healthy person developing the condition or because they represent signs or symptoms of either subclinical or overt TMD. In this baseline case-control study of the multisite Orofacial Pain: Prospective Evaluation and Risk Assessment (OPPERA) project, 1,633 controls and 185 cases with chronic, painful TMD completed questionnaires and received clinical examinations. Odds ratios measuring association between each clinical factor and TMD were computed, with adjustment for study-site as well as age, sex, and race/ethnicity. Compared to controls, TMD cases reported more trauma, greater parafunction, more headaches and other pain disorders, more functional limitation in using the jaw, more nonpain symptoms in the facial area, more temporomandibular joint noises and jaw locking, more neural or sensory medical conditions, and worse overall medical status. They also exhibited on examination reduced jaw mobility, more joint noises, and a greater number of painful masticatory, cervical, and body muscles upon palpation. The results indicated that TMD cases differ substantially from controls across almost all variables assessed. Future analyses of follow-up data will determine whether these clinical characteristics predict increased risk for developing first-onset pain-related TMD Perspective Clinical findings from OPPERA’s baseline case-control study indicate significant differences between chronic TMD cases and controls with respect to trauma history, parafunction, other pain disorders, health status, and clinical examination data. Future analyses will examine their contribution to TMD onset. PMID:22074750

    Full Text Available Introduction. The seizure propagation phenomenon by inducing remote symptoms brings several difficulties in finding the seizure onset and delineating the epileptic network which should be taken into consideration in epilepsy surgery. By demonstrating a difficult (MRI negative epilepsy surgery case explored with invasive presurgical evaluation we highlight the importance to recognise the secondary sensory area and to explore the the parieto-opercular-insular-medial frontal network in certain cases. A further conclusion is the consideration of the redistributory role of the insula as a special structure in the cerebral connectome, having a role in epileptic network organisation.

    Full Text Available Phlegmonous gastritis is a rare bacterial infection of the gastric wall, which progress rapidly. It is characterized by a purulent inflammation that can affect the entire gastrointestinal tract and presents a high mortality rate. We are reporting a case of phlegmonous gastritis in an HIV-seropositive man successfully treated with antibiotics. Moreover, a review of the English and Spanish literature is carried out, from 1980 to the present time. The most frequently involved microorganism is Streptococcus spp. (57 %, but the polimicrobial infection is also frequent (17 %. The most important symptom is the intensive epigastric pain associated with vomits and most cases were diagnosed by CT and/or fibrogastroscopy. There are many existing risk factors described. The main one is the immunesuppression, although in 40 % of the cases no risk factors were identified. The global mortality is 27 % without identifying significant differences between antibiotics and surgical treatment, for that reason it is recommended to initiate antibiotic treatment right from the beginning and postponing surgery for the refractory cases and complications.

    Highlights: • Characteristics of Ag-supported MgO(100) films are studied with different DFT functionals. • All approaches predict a similar nature of supported pristine and oxygen-deficient films. • Interface distances and adhesion are particularly sensitive to the choice of the approximation. • Satisfactory matching with the experiment is obtained with the DFT-optB88 functional. • Charge transfer, work function and vacancy characteristics are little influenced by the method. - Abstract: We compare the performances of different DFT functionals applied to ultra-thin MgO(100) films supported on the Ag(100) surface, a prototypical system of a weakly interacting oxide/metal interface, extensively studied in the past. Beyond semi-local DFT-GGA approximation, we also use the hybrid DFT-HSE approach to improve the description of the oxide electronic structure. Moreover, to better account for the interfacial adhesion, we include the van de Waals interactions by means of either the semi-empirical force fields by Grimme (DFT-D2 and DFT-D2*) or the self-consistent density functional optB88-vdW. We compare and discuss the results on the structural, electronic, and adhesion characteristics of the interface as obtained for pristine and oxygen-deficient Ag-supported MgO films in the 1–4 ML thickness range.

    To review patients that have undergone correction of a symptomatic femoral malunion using osteotomy combined with decortication. A retrospective review of all patients who have undergone decortication and multiplanar osteotomy, looking at the pre-operative deformity, correction achieved, time to union and complications. Seven patients underwent correction under the senior author from 2003 to 2012. Average age was 46 years (range 32-60 years). All had femoral shortening deformity (average 2.7 cm, range 2-4 cm). Each also had at least one other plane of deformity with rotation being the next most commonly encountered in 5 out of the 7 (average 33°, range 0°-45°). Two had tri-planar deformity with the five having bi-planar deformity. Average time to union was 16.3 months (range 7-39 months) with an average of 1.5 operations (range 1-3 operations) to union. One patient has a non-union after five corrective operations. Correction of multiplanar deformity of the femur is challenging. Osteotomy with decortication provides a technique to achieve significant femoral multiplanar deformity correction in a single operation. This publication provides technical description of the operative technique, guidance and results.

    Background We present our experience in the treatment of patients with isthmic or degenerative spondylolisthesis, by means of a posterior lumbar interbody fusion (PLIF) and instrumented posterolateral fusion (IPLF), and we compare them with those published in the literature. We analyse whether there exists any statistical association between the clinical characteristics of the patient, radiological characteristics of the disease and our surgical technique, with the complications and the clinical-radiological prognosis of the cases. Method We designed a prospective study. A total of 36 cases were operated. The patients included were 14 men and 22 women, with an average age of 57.17±27.32 years. Our technique consists of PLIF+IPLF, using local bone for the fusion. The clinical results were evaluated with the Visual Analogical Scale (VAS) and the Kirkaldy-Willis criteria. The radiological evaluation followed the Bratingan (PLIF) and Lenke (IPLF) methodology. A total of 42 variables were statistically analysed by means of SPSS18. We used the Paired Student's T-test, logistic regression and Pearson's Chi-square-test. Results The spondylolisthesis was isthmic in 15 cases and degenerative in 21 cases. The postoperative evaluations had excellent or good results in 94.5% (n = 34), with a statistically significant improvement in the back pain and sciatica (p spondylolisthesis, isthmic or degenerative, refractory to conservative treatment, for the obtaining the best clinical results and rates of fusion, with similar risks to those of the other published techniques. Our statistical analysis could contribute to improve outcomes after surgery. PMID:26196029

    Introduction. White Sponge Nevus (WSN) is a rare pathology with a pathogenesis on genetic basis, a benign course and a localization affecting the mucosal keratin. WSN is usually a symptomless pathology: when pain is present, some authors reported reduction of symptoms by taking penicillin or oral tetracycline rinses, suggesting that a bacterial overinfection could be at the base of possible painful symptoms. Case Report. We describe 2 patients affected by WSN, father and son: they presented two different oral diseases associated with an infection by Staphylococcus aureus. So, we have performed a careful oral hygiene to reduce infection in the oral cavity. In the following days we prescribed 2 rinses a day with a mouthwash containing chlorhexidine digluconate at two different percentages. Discussion. Early diagnosis of this lesion is important, because it allows us to exclude other more serious diseases. In the most part of cases, WSN requires no treatment because of its benign and asymptomatic behaviour: up to now, no protocol of treatment for this condition was standardized. Even if WSN is a painless condition, sometime a correlated painful symptomatology was reported. Conclusions. In our experience, we have achieved excellent results even with chlorhexidine digluconate rinses, considering that our treated cases were both infected by Staphylococcus aureus. We hypothesize that the corrugated plaques and the altered texture of the mucosa create the right conditions for the colonization and the development of microbial species such as saprophytic bacteria or fungal species.

    Calcific tendinitis is a common and widespread disease. It is most common in the rotator cuff especially in the supraspinatus tendon. In some cases it may also involve other locations such as the hips, particularly at the trochanter minor. In particular calcific tendinitis of the iliopsoas muscle tendon has not yet been described. Because of uncharacteristic symptoms and ambiguous diagnostic imaging the differentiation between traumatic, infectious and neoplastic genesis is often difficult. Because of artefacts the typical calcareous spots near the insertions are often underdiagnosed in conventional diagnostic x-ray images. In this case report the differentiation from an infection of the hip was only possible with positron emission tomography computed tomography (PET-CT) imaging and negative microbiological testing of an aspirate. There are various therapy options, such as systemic and local medication, extracorporeal shock wave therapy up to surgery. However, calcific tendinitis is a self-limiting tendinopathy that can be treated with conservative therapy to complete remission in most cases.

    Klippel-Feil syndrome is characterized by faulty segmentation of two or more cervical vertebrae and, in its most severe form, consists of massive cervical vertebral fusion, short neck, low posterior hairline, and limitation of head movement. Several cases associating Klippel-Feil syndrome with situs inversus totalis have been reported. In the present study, we describe the clinical features of a novel case of Klippel-Feil syndrome associated with situs inversus totalis and searched for mutations in GDF1, GDF3 and GDF6 genes, which were recently implicated in the development of skeletal and visceral anomalies. A case of Klippel-Feil syndrome associated with situs inversus totalis underwent a full clinical examination including X-ray of cervical spine and thorax, abdominal ultrasound, and computerized tomography scanning of thorax and abdomen. PCR amplification and automated nucleotide sequencing of coding exons and intron-exon junctions of GDF1, GDF3, and GDF6 genes were performed in genomic DNA. No molecular alterations were found in GDF1, GDF3 and GDF6 genes in this patient. An additional patient associating Klippel-Feil syndrome and situs inversus totalis is reported. Mutations in GDF1, GDF3, and GDF6 genes were excluded as the cause of this unusual clinical association. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

    2010-06-01

    Low back pain and leg pain commonly occur together. Multiple factors can cause low back related leg pain; therefore, identification of the source of symptoms is required in order to develop an appropriate intervention program. The patient in this case presented with low back and leg pain. A patho-mechanism based classification is described in combination with the patient's subjective and objective examination findings to guide treatment. The patient's symptoms improved marginally with intervention addressing primarily the musculoskeletal impairments and with intervention addressing primarily the neurodynamic impairments. Full functional improvements were attained with a manual therapy intervention directed at both mechanisms simultaneously. The approach described in this case address a mixed pathology utilizing passive accessory and passive physiological lumbar mobilizations in combination with lower extremity neurodynamic mobilization. The patient reported complete resolution of symptoms after a total of seven visits over a period of 6 weeks. While specific guidelines do not yet exist for treatment based on the classification approach utilized, this case report provides an example of manual therapy to address low back related leg pain of mixed pathology.

    Invasive lobular carcinoma of the breast is known to produce intracellular mucin and has been recognized in single-case reports to show extracellular mucin production, as well. This latter morphology is not only rare but must also be under- or misdiagnosed. The aim was to better characterize this entity. Cases of lobular cancers demonstrating extracellular mucin formation were identified in a multi-institutional effort and their clinical and morphologic features were assessed. Immunohistochemistry was used to characterize the E-cadherin-membrane complex, neuroendocrine differentiation, and to some extent, mucin formation. All but one of the eight cases occurred in postmenopausal patients. Extracellular mucin production was present in 5 to 50% of the tumour samples and rarely also appeared in nodal and distant metastases. The tumours were completely E-cadherin negative and showed cytoplasmic p120 positivity. The majority (n = 6/8) was also completely negative for β-catenin, but two tumours displayed focal β-catenin positivity in the mucinous area. MUC1 and MUC2 expression was observed in all and 7/8 tumours, respectively; neuroendocrine differentiation was present in only one. Invasive lobular carcinoma with extracellular mucin formation is a rare morphologic variant of lobular carcinoma prone to be misdiagnosed and warranting further studies.

    Full Text Available Abstract Background We present a descriptive and retrospective analysis of revision total hip arthroplasties (THA using the MRP-TITAN stem (Peter Brehm, Weisendorf, GER with distal diaphyseal fixation and metaphyseal defect augmentation. Our hypothesis was that the metaphyseal defect augmentation (Impaction Bone Grafting improves the stem survival. Methods We retrospectively analyzed the aggregated and anonymized data of 243 femoral stem revisions. 68 patients with 70 implants (28.8% received an allograft augmentation for metaphyseal defects; 165 patients with 173 implants (71.2% did not, and served as controls. The mean follow-up was 4.4 ± 1.8 years (range, 2.1–9.6 years. There were no significant differences (p > 0.05 between the study and control group regarding age, body mass index (BMI, femoral defects (types I-III as described by Paprosky, and preoperative Harris Hip Score (HHS. Postoperative clinical function was evaluated using the HHS. Postoperative radiologic examination evaluated implant stability, axial implant migration, signs of implant loosening, periprosthetic radiolucencies, as well as bone regeneration and resorption. Results There were comparable rates of intraoperative and postoperative complications in the study and control groups (p > 0.05. Clinical function, expressed as the increase in the postoperative HHS over the preoperative score, showed significantly greater improvement in the group with Impaction Bone Grafting (35.6 ± 14.3 vs. 30.8 ± 15.8; p ≤ 0.05. The study group showed better outcome especially for larger defects (types II C and III as described by Paprosky and stem diameters ≥ 17 mm. The two groups did not show significant differences in the rate of aseptic loosening (1.4% vs. 2.9% and the rate of revisions (8.6% vs. 11%. The Kaplan-Meier survival for the MRP-TITAN stem in both groups together was 93.8% after 8.8 years. [Study group 95.7% after 8.54 years ; control group 93

    Full Text Available BACKGROUND: The world's first reported patient infected with avian influenza H7N9 was treated at the Fifth People's Hospital of Shanghai. Shortly thereafter, several other cases emerged in the local area. Here, we describe the detailed epidemiological and clinical data of 6 cases of avian influenza H7N9. METHODS AND FINDINGS: We analyzed the epidemiologic and clinical data from clustered patients infected with H7N9 in the Minhang District of Shanghai during a 2-week period. Of the 6 patients, 2 were from a single family. In addition, 3 patients had a history of contact with poultry; however, all 6 patients lived in the proximity of 2 food markets where the H7N9 virus was detected in chickens and pigeons. The main symptoms were fever, cough, and hemoptysis. At onset, a decreased lymphocyte count and elevated creatine kinase, lactate dehydrogenase, procalcitonin, and C-reactive protein levels were observed. As the disease progressed, most patients developed dyspnea and hypoxemia. Imaging studies revealed lung consolidation and multiple ground-glass opacities in the early stage, rapidly extending bilaterally. All patients were treated with oseltamivir tablets beginning on days 3-8 after onset. The main complications were as follows: acute respiratory distress syndrome (ARDS; 83.3%, secondary bacterial infection (66.7%, pleural effusion (50%, left ventricular failure (33.3%, neuropsychiatric symptoms (33.3%, and rhabdomyolysis (16.7%. Of the 6 patients, 4 died of ARDS, with 2 patients recovering from the infection. CONCLUSIONS: An outbreak of H7N9 infection occurred in the Minhang District of Shanghai that easily progressed to acute respiratory distress syndrome. Two cases showed family aggregation, which led us to identify the H7N9 virus and indicated that human transmission may be involved in the spread of this infection.

    Full Text Available Eosinophilic meningoencephalitis (EME has been described in various species of animals and in humans. In dogs it has been associated with protozoal infections, cuterebral myiasis and various other aetiologies. Ten cases of idiopathic eosinophilic meningoencephalitis have been reported in dogs and one in a cat where the origin was uncertain or unknown. The dogs were all males, of various breeds but with a predominance of Golden Retrievers and Rottweilers; they generally had a young age of onset. Two cases with no apparent underlying aetiology were diagnosed on post mortem examination. The 18-month-old, male Boerboel presented with sudden onset of cerebellar ataxia, as well as various asymmetrical cranial nerve deficits of 2 weeks' duration and without progression. Haematology revealed a peripheral eosinophilia. Necropsy showed extreme generalised congestion especially of the meninges and blood smear and histological sections of various tissues showed intravascular erythrocyte fragmentation with the formation of microcytes. Histopathology revealed severe diffuse cerebrocortical subarachnoidal meningitis and submeningeal encephalitis, the exudate containing variable numbers of eosinophils together with neutrophils and mononuclear cells. There was also deeper white matter and hippocampal multifocal perivascular mononuclear encephalitis and multifocal periventricular malacia, gliosis and phagocytosis of white matter. The cerebellum, brain stem and spinal cord showed only mild multifocal oedema or scattered occasional axon and myelin degeneration respectively, with no inflammation. Immunohistochemical staining of central nervous tissue for Toxoplasma gondii failed to show any antigen in the central nervous tissue. Ultrastructure of a single submeningeal suspected parasitic cyst showed it to be chromatin clumping within a neuron nucleus indicating karyorrhexis. Gram stain provided no evidence of an aetiological agent. The 3-year-old Beagle bitch had a

    Full Text Available Cognitive-behavioral Therapy (CBT for the treatment of Intermittent Explosive Disorder (IED has proved to be effective, with moderate to large effect sizes both in individual and group interventions. Videoconferencing has been used effectively to treat different mental disorders but its use for IED patients is as yet unknown. The aim of this study is to provide preliminary evidence of the possibility of treating IED by videoconference. We present a case-study experiment of a Spanish male, aged 33 years, living and working in China. After the intervention, the patient's aggressive episodes decreased dramatically, as well as his negative affect. In contrast, he showed an important increment in positive emotions and self-esteem. There were also positive changes in some personality dimensions and facets measured by NEO-PI-R, specifically in neuroticism, extraversion, and agreeableness. The benefits were maintained at 3-, 8- and 18-month follow-ups. These preliminary results reveal that CBT by videoconference oriented to increasing emotion regulation skills was effective when implemented in a case study of a person suffering from IED.

    Incidence rates of pleural mesothelioma in Ile de France were examined for the period 1987-1990, on the basis of information collected in a case-control study. This study was designed to include all new cases of pleural mesothelioma occurring in the region. On the other hand, mortality rates from pleural malignancies in the same region were examined on the basis of death certificates recorded by INSERM for the same period. A large difference was found between the two types of data. Average annual incidence rates were 7.5 per million among men and 1.6 per million among women. Average annual mortality rates due to primary pleural malignancies were 25.2 per million in males and 8.9 per million in females. This study confirms discordances between incidence and mortality data for pleural malignancies already reported in several countries. However, contrasting with some previous reports, the annual mortality rate from pleural malignancies was higher than the incidence rate of mesothelioma in this study. This emphasizes the usefulness of a specific investigation to explain such discordances, prior to comparison of data from one country to another.

    Human papillomavirus (HPV)-negative cervical carcinomas are uncommon and typically encompass unusual histologic subtypes. Mesonephric adenocarcinoma is one such subtype. Mesonephric tumors in the female genital tract are thought to arise from Wolffian remnants, and are extremely rare tumors with widely variable morphology. Sarcomatoid dedifferentiation has been previously described in a few cases, but other forms of dedifferentiation have not been reported. Neuroendocrine carcinoma of the cervix (e.g. small cell carcinoma) is associated with HPV infection, typically HPV 18. These tumors often arise in association with a conventional epithelial component such as squamous cell carcinoma or usual-type endocervical adenocarcinoma. We describe a case of mesonephric adenocarcinoma of the uterine cervix associated with an HPV-negative high-grade neuroendocrine carcinoma at the morphologic and immunophenotypic level, for which we performed targeted massively parallel sequencing analysis of the 2 elements. Both components shared identical mutations in U2AF1 p.R156H (c.467G>A) and GATA3 p.M422fs (c.1263dupG), as well as MYCN amplification. In addition, the neuroendocrine carcinoma harbored TP53 and MST1R mutations not present in the mesonephric carcinoma. Our data suggest a clonal origin of the 2 components of this rare entity, rather than a collision tumor.

    Protease inhibitors boosted with ritonavir can lead to drug-drug interactions, particularly with inhaled corticosteroids such as fluticasone, because of the potent inhibition of cytochrome P450-3A4 activity. We report 4 cases of iatrogenic Cushing's syndrome after concomitant administration of inhaled fluticasone and antiretroviral therapy including a protease inhibitor boosted with ritonavir. Although typical manifestations were present, diagnosis of Cushing's syndrome was delayed because the patients were suspected to have antiretroviral therapy-associated lipodystrophy, which shares common clinical features with Cushing's syndrome. Biochemical tests confirmed iatrogenic Cushing's syndrome and clinical symptoms resolved after stopping ritonavir or fluticasone. The differences between the clinical symptoms of Cushing's syndrome and lipodystrophy are discussed as well as their frequency in the cases reported in the literature. The recommendation that concomitant administration of inhaled or intranasal fluticasone and ritonavir be prohibited must be implemented among practitioners who treat HIV-infected patients, and if long-term inhaled steroids are required, other drugs should be preferred.

    The aim of the present case study is to illustrate the outcomes of a dedicated allied health (AH) research position within a large Queensland regional and rural health service. The secondary aim of the case study is to describe the enabling and hindering mechanisms to the success of the role. Semistructured interviews were conducted with the Executive Director of Allied Health and the current AH research fellow incumbent within the health service. A focus group was also undertaken with six stakeholders (e.g. clinicians, team leaders) who had engaged with the research position. Outcomes of the AH research fellow included clinical and service improvements, enhanced research culture and staff up-skilling, development of research infrastructure and the formation of strategic research collaborations. Despite being a sole position in a geographically expansive health service with constrained resources, key enabling mechanisms to the success of the role were identified, including strong advocacy and regular communication with the Executive. In conclusion, the case study highlights the potential value of an AH research position in building research capacity within a large non-metropolitan health service. Factors to facilitate ongoing success could include additional research and administrative funding, as well as increased use of technology and team-based research.What is known about the topic? Dedicated research positions embedded within health care settings are a well cited strategy to increase research capacity building of allied health professionals (AHPs). However the majority of these positions are within metropolitan health settings and unique challenges exist for these roles in regional and rural areas. Few studies have described the impact of dedicated AH research positions within regional health centres or the factors which facilitate or hinder their role.What does this paper add?

    Full Text Available Abstract Background The community’s awareness of Tuberculosis (TB and delays in health care seeking remain important issues in Indonesia despite the extensive efforts of community-based TB programs delivered by a non-government organisation (NGO. This study explored the knowledge and behaviours in relation to TB and early diagnosis before and after an asset-based intervention designed to improve these issues. Methods Six villages in Flores, Indonesia were purposively selected to participate in this study. Three villages served as intervention villages and the other three villages provided a comparison group. Data collection included interviews, group discussions, observations, field notes and audit of records. Results In total, 50 participants across six villages were interviewed and three group discussions were conducted in the intervention villages supplemented by 1 – 5 h of observation during monthly visits. Overall, participants in all villages had limited knowledge regarding the cause and transmission of TB before the intervention. The delay in health seeking behaviour was mainly influenced by ignorance of TB symptoms. Health care providers also contributed to delayed diagnosis by ignoring the symptoms of TB suspects at the first visit and failing to examine TB suspects with sputum tests. Stigmatisation of TB patients by the community was reported, although this did not seem to be common. Early case detection was less than 50 % in four of the six villages before the asset-based intervention. Knowledge of TB improved after the intervention in the intervention villages alongside improved education activities. Early case detection also increased in the intervention villages following this intervention. The behaviour changes related to prevention of TB were also obvious in the intervention villages but not the comparison group. Conclusion This small project demonstrated that an asset-based intervention can result in positive changes in

    Persistent trigeminal artery (PTA) is the most frequent embryonic communication between the carotid and vertebrobasilar systems. However, hormonal changes or the association of PTA with other sellar lesions, such as pituitary adenomas, are extremely rare. The aim of the present study was to report two patients with intrasellar PTA and simultaneous pituitary adenoma in order to emphasize the importance of differential diagnoses for sellar lesions. Case 1. A female patient, 41 years old, was admitted with a history of chronic headache (> 20 years). Pituitary magnetic resonance imaging (MRI) showed a rounded lesion in the left portion of the pituitary gland suggestive of adenoma (most likely clinically non-functioning adenoma). In addition to this lesion, the MRI demonstrated ecstasy of the right internal carotid artery and imaging suggestive of an intrasellar artery that was subsequently confirmed by an angio-MRI of the cerebral vessels as PTA. Case 2. A female patient, 42 years old, was admitted with a history of amenorrhea and galactorrhea in 1994. Laboratorial investigation revealed hyperprolactinemia. Pituitary MRI showed a small hyposignal area in the anterior portion of pituitary gland suggestive of a microadenoma initiated by a dopaminergic agonist. Upon follow-up, aside from the first lesion, the MRI showed a well delineated rounded lesion inside the pituitary gland, similar to a vessel. Angio-MRI confirmed a left primitive PTA. Failure to recognize these anomalous vessels within the sella might lead to serious complications during transsphenoidal surgery. Therefore, although their occurrence is uncommon, a working knowledge of vascular lesions in the sella turcica or pituitary gland is important for the differential diagnosis of pituitary lesions, especially pituitary adenomas.

This study included all consecutive patients referred to the Department of Rheumatology at Karolinska University Hospital for the investigation of incident pSS from 1 January 2007 to 31 December 2011. Investigation was according to the current criteria for pSS, and examination with a focus on the presence of EGMs was performed. Of the referred individuals, 199 out of 781 were diagnosed with pSS. We found an annual incidence rate of pSS in the Karolinska University Hospital catchment area of 3.1 [95% confidence interval (CI) 2.3-4.3] cases per 100 000 adult inhabitants. The female/male ratio of incident cases was 14/1 [frequency (female) = 0.93, 95% CI 0.89-0.96]. In our cohort, we noted lower figures for severe EGMs such as lung and neurological involvement than previously reported for prevalent pSS. The frequency of autoantibodies including antinuclear antibodies (ANA), anti-Ro/SSA, and anti-La/SSB was also lower compared to other cohorts. In our study, autoantibody-positive patients had cytopaenia significantly more often, and in patients older than 60 years primary biliary cirrhosis (PBC) was more common. The incidence rate of pSS is 3.1 (95% CI 2.3-4.3) per 100 000 person-years. The prevalence of autoantibodies may be lower than previously reported, and at diagnosis, patients with pSS have few severe EGMs.

  15. Importance of polarization in quantum mechanics/molecular mechanics descriptions of electronic excited states: NaI(H2O)n photodissociation dynamics as a case study.

    Sodium iodide has long been a paradigm for ionic and covalent curve crossing and ultrafast nonadiabatic dynamics, and our interest lies in the influence of solvation on this process. The NaI(H2O)n photodissociation dynamics are simulated with the molecular dynamics with quantum transitions method. A quantum mechanics/molecular mechanics (QM/MM) description is adopted for the NaI(H2O)n electronic states, in which a semiempirical valence bond approach is used to describe the NaI electronic structure, and a polarizable optimized potential for cluster simulations model is used to describe solute-solvent and solvent-solvent interactions. In contrast to previous work with a nonpolarizable MM model [Koch et al., J. Phys. Chem. A, 2006, 110, 1438], this approach predicts that the NaI ionic ground- to covalent first-excited-state Franck-Condon energy gaps reach a plateau by cluster size 16, in relatively good agreement with experiment and electronic structure calculations; this allows us to safely extend our previous simulations to larger cluster sizes, i.e., n > 4. The simulations suggest that the disappearance of the two-photon ionization probe signals observed in femtosecond pump-probe experiments of NaI(H2O)n, n >/= 4, is due to the shift of the NaI curve-crossing region toward larger NaI internuclear separations because of solvent stabilization of the NaI ionic state. Further, the latter causes the adiabatic ground and excited states to acquire pure ionic and covalent character, respectively, by cluster 8, resulting in NaI ionic ground-state recombination or dissociation. To make a connection with electron transfer in solution, free energy curves have been generated as a function of a solvent coordinate similar to that of solution theory. Inspection of the free energy curves together with the results of excited-state simulations reveal that the electron-transfer process in clusters is not governed by the collective motion of the solvent molecules, as in solution, but

    Full Text Available Metabolic syndrome (MS is extremely common (20%–25% of the world’s population, and its diagnostic criteria are defined and well known. It has been shown that patients who have MS are twice as likely to die from a cardiovascular complication and three times as likely to suffer from it compared with patients without MS. However, the underlying cause of MS remains to be clearly elucidated, although inherited factors, such as insulin resistance (IR, and external factors are considered to play a key role in this process. Special attention should be paid to MS in young patients, who may present the first manifestation of inherited lipodystrophy. The study describes the first known family in Russia (three clinical cases with familial partial lipodystrophy (FPLD type 3 caused by heterozygous p.R212Q PPARG mutation (MIM#601487. The study reports rare forms of inherited IR, such as FPLD, and contributes to a better understanding of common disorders such as MS.

    Full Text Available Current criteria for differential diagnosis of multiple myeloma (MM, Monoclonal gammopathy of undetermined significance (MGUS, and smoldering multiple myeloma (SMM are included in the 2003 guidelines by the International Myeloma Working Group (IMWG. An updated version was then published in 2014, highlighting the importance of serum free light chain (sFLC detection, as well as the κ/λ ratio as excellent indicators of clonality. At present, two commercial assays for sFLC quantification are available: the Freelite™ assay and the N-Latex assay. The first was developed by The Binding Site based on a mixture of polyclonal antibodies directed against a variety of FLC epitopes. It may be run on a wide range of nephelometers, as well as on turbidimeters. The second method was developed by Siemens and runs exclusively on Siemens instruments. It employs a probe mixture of mouse monoclonal antibodies. The aim of our study was to evaluate sFLC measurement and calculated κ/λ ratio in 85 patients with monoclonal gammopathies (MGs in order to compare methods. We demonstrated that there is only a moderate concordance between the two FLC assays. In particular, in one case, we observed no qualitative alterations of the serum protein pattern, and in the absence of a Freelite™ assay, sFLC measurement would not have been possible to highlight the increase of λ FLC.

    Full Text Available The use of the oncological principle – en bloc ablastic tumor resection – can expect a breakthrough in the treatment of baseline unfavorable patient groups. In the described case of atypical meningioma, its en bloc resection presents significant technical difficulties when accomplishing the task associated with the giant sizes of a tumor as an iceberg growing outside and into the cranial cavity, its rich vascularization from both the internal and external carotid artery system, with the involvement of the superior sagittal sinus, the presence of a dense bone crown that combines the three-component construction of a neoplasm, which made difficult safe mobilization and scanning in the cranial cavity.In such topographic variants, the criteria for the Simpson radical meningioma resection are inapplicable and only en bloc tumor resection may reflect the oncological principles of surgery. The technologies of en bloc resection of intracranial meningiomas should be more frequently used because preoperative neurovisualization and even histological diagnosis does not always allow the grade of meningiomas to be specified.

  1. Ignoring Grounded Description

    Barney G. Glaser, PhD, Hon. PhD

    2016-12-01

    Full Text Available Why is there so much grounded description? The simplest, direct answer is that to many a researcher this is GT. This view is supported by several factors. It is easy and natural to describe accurately. So slipping into grounded description comes naturally and is ok as GT. Also departmental support for description is strongly supported by perspective and academic rewards and history and routine QDA. Also many researchers and readers of research cannot conceptualize very well if at all. They want accurate description about the data in the study. They are not into taking a core category as a general category applicable to general implications applicable to much data elsewhere. Their study is about explaining processes the data, NOT in studying the implications of core and sub-core categories as they are integrated into an explanatory theory. I trust the reader can think of other sources of letting GT research slip into conceptual description.

  2. Application of the Price-Volume Approach in Cases of Innovative Drugs Where Value-Based Pricing is Inadequate: Description of Real Experiences in Italy.

    Several cases of expensive drugs designed for large patient populations (e.g. sofosbuvir) have raised a complex question in terms of drug pricing. Even assuming value-based pricing, the treatment with these drugs of all eligible patients would have an immense budgetary impact, which is unsustainable also for the richest countries. This raises the need to reduce the prices of these agents in comparison with those suggested by the value-based approach and to devise new pricing methods that can achieve this goal. The present study discusses in detail the following two methods: (i) The approach based on setting nation-wide budget thresholds for individual innovative agents in which a fixed proportion of the historical pharmaceutical expenditure represents the maximum budget attributable to an innovative treatment; (ii) The approach based on nation-wide price-volume agreements in which drug prices are progressively reduced as more patients receive the treatment. The first approach has been developed in the USA by the Institute for Clinical and Economic Review and has been applied to PCSK9 inhibitors (alirocumab and evolocumab). The second approach has been designed for the Italian market and has found a systematic application to manage the price of ranibizumab, sofosbuvir, and PCSK9 inhibitors. While, in the past, price-volume agreements have been applied only on an empirical basis (i.e. in the absence of any quantitative theoretical rule), more recently some explicit mathematical models have been described. The performance of these models is now being evaluated on the basis of the real-world experiences conducted in some European countries, especially Italy.

    OBJECTIVE To describe the prevalence, histologic characteristics, concomitant abnormalities, and outcomes for various types of mammary gland tumors in companion rats (Rattus norvegicus). DESIGN Retrospective case series. ANIMALS 100 client-owned rats. PROCEDURES Medical records of companion rats that had an SC mass and were examined at a veterinary teaching hospital between 1990 and 2015 were reviewed. Information regarding the signalment, age at mass detection, reproductive sterilization status, histologic diagnosis of the SC mass, location of the initial and all subsequent SC masses, treatments administered, and clinical outcomes was extracted from each record and summarized. RESULTS 105 SC masses were initially detected in 100 rats. The most prevalent SC mass identified was mammary gland fibroadenoma (56/105 [53%]), followed by mammary gland carcinoma (13/105 [12%]). Overall, 26 of 105 (25%) masses were malignant. Sexually intact males were more likely to have nonmammary SC tumors than sexually intact females. In rats receiving no adjunctive treatment after excision of a mammary gland fibroadenoma (n = 16), a second fibroadenoma was detected 1 to 8 months after initial excision, at a median of 4.5 months after surgery. A concomitant pituitary gland tumor was identified in most rats with mammary gland fibroadenoma (21/28 [75%]) and other types of mammary gland tumors (10/17 [59%]). Fourteen of 35 (40%) rats with mammary gland fibroadenoma had concomitant reproductive tract abnormalities. CONCLUSION AND CLINICAL RELEVANCE Results suggested that, like other species, companion rats with SC masses should undergo a thorough diagnostic workup that includes histologic examination of the excised mass.

  4. Is mesocardia with left-sided caval vein draining to coronary sinus a contraindication for a percutaneous pulmonary valve implantation? A case description.

    2017-10-04

    Introduction Although the right jugular vein approach for percutaneous pulmonary valve implantation is well described, there are no reports that describe a percutaneous pulmonary valve implantation through a left superior caval vein to coronary sinus pathway. Case A 14-year-old female with tetralogy of Fallot, mesocardia, left superior caval vein draining into the coronary sinus, and hemiazygos continuation of the inferior caval vein underwent ventricular septal defect closure, with homograft insertion from the right ventricle to the pulmonary artery, patch augmentation of the left pulmonary artery, and creation of an atrial communication. Thereafter followed numerous catheterisations and interventions with stent implantation for stenosis of the left pulmonary artery and the homograft, as did device closure of the atrial communication. When she was a 12-year-old, the indications for a percutaneous pulmonary valve implantation were fulfilled and she underwent implantation of a 22 mm Melody® valve through the left superior caval vein. The extra-stiff exchange wire was pre-formed into a "U-spiral"-type configuration, according to the underlying anatomy, in order to provide a smooth route for the delivery of stents, to create the landing zone, and for the implantation of the Melody "ensemble". The procedure was performed under deep sedation according to our standard protocol. The duration of the procedure was 172 min and the radiation time was 24.9 min. On the basis of this unique experience, percutaneous pulmonary valve implantation is safe and feasible even in patients with unusual anatomy. Crucial is the "U-spiral" shaped configuration of the guide wire.

    Full Text Available Although descriptive passages would appear to be of marginal importance in narrative texts, they are, in fact, of both logical and semantic necessity. Narratology, therefore, must take these segments into account. In this article, I shall survey the present situation in this field and compare rival points of view. I shall also offer several suggestions for analyzing descriptions. The following topics will be discussed: the nature of description as a specific type of discourse which makes it recognizable as such; the internal structure of description; the place and function of descriptions in the text as a whole. In the latter section, the semantic impact of descriptions in the overall meaning of narrative texts will be accounted for. This article is intended as a contribution to the theory of description as a part of narratology. It also has a didactic purpose, since it proposes a model for the analysis of texts which can be used for systematic text-study, both in a historical and a comparative perspective.

    Full Text Available Misophonia is a relatively unexplored chronic condition in which a person experiences autonomic arousal (analogous to an involuntary fight-or-flight response to certain innocuous or repetitive sounds such as chewing, pen clicking and lip smacking. Misophonics report anxiety, panic and rage when exposed to trigger sounds, compromising their ability to complete everyday tasks and engage in healthy and normal social interactions. Across two experiments, we measured behavioral and physiological characteristics of the condition. Interviews (Experiment 1 with misophonics showed that the most problematic sounds are generally related to other people's behavior (pen clicking, chewing sounds. Misophonics are however not bothered when they produce these trigger sounds themselves, and some report mimicry as a coping strategy. Next, (Experiment 2 we tested the hypothesis that misophonics’ subjective experiences evoke an anomalous physiological response to certain auditory stimuli. Misophonic individuals showed heightened ratings and skin conductance responses to auditory, but not visual stimuli, relative to a group of typically developed controls, supporting this general viewpoint and indicating that misophonia is a disorder that produces distinct autonomic effects not seen in typically developed individuals.

    Seizure semiology is important for classifying patients' epilepsy. Physicians usually get most of the seizure information from observers though there have been few reports on the reliability of the observers' description. This study aims at determining the reliability of observers' description of the semiology. We included 92 patients who had their habitual seizures recorded during video-EEG monitoring. We compared the semiology described by the observers with that recorded on the videotape, and reviewed which characteristics of the observers affected the reliability of their reported data. The classification of seizures and the individual components of the semiology based only on the observer-description was somewhat discordant compared with the findings from the videotape (correct classification, 85%). The descriptions of some ictal behaviors such as oroalimentary automatism, tonic/dystonic limb posturing, and head versions were relatively accurate, but those of motionless staring and hand automatism were less accurate. The specified directions by the observers were relatively correct. The accuracy of the description was related to the educational level of the observers. Much of the information described by well-educated observers is reliable. However, every physician should keep in mind the limitations of this information and use this information cautiously.

    2000-01-01

    Before the Career Path system, jobs were classified according to grades with general statutory definitions, guided by the "Job Catalogue" which defined 6 evaluation criteria with example illustrations in the form of "typical" job descriptions. Career Paths were given concise statutory definitions necessitating a method of description and evaluation adapted to their new wider-band salary concept. Evaluations were derived from the same 6 criteria but the typical descriptions became unusable. In 1999, a sub-group of the Standing Concertation Committee proposed a new guide for describing Career Paths, adapted to their wider career concept by expanding the 6 evaluation criteria into 9. For each criterion several levels were established tracing the expected evolution of job level profiles and personal competencies over their longer salary ranges. While providing more transparency to supervisors and staff, the Guide's official use would be by services responsible for vacancy notices, Career Path evaluations and rela...

Authors struggle and struggle to find and rationalize a way to use them and then fail in spite of trying a myriad of work-arounds. And then we have Lincoln and Guba’s famous statement: “The only generalization is: there is no generalization” in referring to qualitative research. (op cit, p. 110 They are referring to routine QDA yielding extensive descriptions, but which tacitly include conceptual generalizations without any real thought of knowledge about them. In this chapter I wish to explore this struggle for the purpose of explaining that the various contra arguments to using descriptive generalizations DO NOT apply to the ease of using conceptual generalizations yielded in SGT and especially FGT. I will not argue for the use of descriptive generalization. I agree with Lincoln and Guba with respect to QDA, “the only generalization is: there is no generalization.” It is up to the QDA methodologists, of whom there are many; to continue the struggle and I wish them well.

  20. Polemic and Descriptive Negations

    DEFF Research Database (Denmark)

    Horslund, Camilla Søballe

    2011-01-01

    to semantics and pragmatics, negations can be used in three different ways, which gives rise to a typology of three different types of negations: 1) the descriptive negation, 2) the polemic negation, and 3) the meta-linguistic negation (Nølke 1999, 4). This typology illuminates the fact that the negation...... as such may be more or less central to the meaning of the utterance. The present paper investigates the role of morphosyntactic and prosodic prominence as well as register and social setting on the interpretation of negations. It seems plausible to expect that if the negation as such is central to the meaning...... of the utterance (as in polemic negations), the negation will be articulated prominently in order to emphasise this importance. Likewise, if the negation is not central to the meaning of the utterance, it should not be articulated prominently. Moreover, it is plausible to expect descriptive negations to be more...

    Quantification of categorical, or non-numerical, data is a problem that scientists face across a wide range of disciplines. Exploring data analysis in various areas of research, such as the social sciences and biology, Multidimensional Nonlinear Descriptive Analysis presents methods for analyzing categorical data that are not necessarily sampled randomly from a normal population and often involve nonlinear relations. This reference not only provides an overview of multidimensional nonlinear descriptive analysis (MUNDA) of discrete data, it also offers new results in a variety of fields. The first part of the book covers conceptual and technical preliminaries needed to understand the data analysis in subsequent chapters. The next two parts contain applications of MUNDA to diverse data types, with each chapter devoted to one type of categorical data, a brief historical comment, and basic skills peculiar to the data types. The final part examines several problems and then concludes with suggestions for futu...

    Full Text Available In recent years, one of the most important developments which have been taking place in the primary school education system is the development of the qualitative-descriptive method of evaluating the students' achievements. The main goals of the qualitative-descriptive evaluation are improving the quality of learning and promoting the level of mental health in teaching-learning environments. Therefore, based on the the raised hypothesis, the purpose of this study is to investigate the teachers' perspecives regarding the descriptive and quantitative methods of evaluation.Using survey sampling method and multi-stage cluster sampling method, 30 teachers, teaching through the qualitative (descriptive method in zone 1 of Tehran were selected. A questionnaire, developed by the researcher of this study, was used to compare the qualitative (descriptive method of evaluation with quantitative evaluation method in order to explore the viewpoints of teachers.Using 1-sample sign test, the results revealed the positive view of teachers towards descriptive evaluation. From the perspective of teachers, quantitavie evaluation has had negative impacts on the mental health of families and students for years. Hence descriptive method of evaluation must match the content of textbooks and whatever the teacher has taught.

  4. Sudden and unpredictable below-surface ablation pattern changes by CO2 laser beams: a qualitative description of five macroscopic cases observed in PMMA with high probability to occur during surgery in low-water-content tissues.

    2002-12-01

    This paper describes five cases of macroscopic irregular CO(2) laser-beam ablation patterns that can generate below-surface complications during surgery. These five cases are related to curved reflected beams, curved craters generation with abnormal superficial thermal damage, and craters that show irregular wall contours. Although these alterations have been observed during irradiation in PMMA samples (polymethilmethacrylate), it is possible that similar unpredictable changes also happen in low-water-content, hard and uniform biological tissues such as compact bone, enamel, and dentin. This fact can predict severe impacts on the quality of the final surgical outcome, especially there where precision surgery techniques are required. A qualitative description about the possible causes of these effects and how to avoid them during surgery have been suggested too. In the past decades, daily surgery and research studies have provided useful information about the interaction between medical CO(2) laser beams and animal, human, and other biological tissues. Several mathematical models describe with acceptable accuracy all the ablative properties of the 10.6 microm laser beam. Very few studies describe the presence and address the consequences of the ablative aberrations, which can frequently and randomly happen during laser surgery. The probability that these changes happen in below-surface, therefore invisible, parts of the biologic media under treatment makes the whole matter crucial, even in cases of traditional surgery. Where gross mass removals are considered, the presence of unpredictable and sudden deviations from the expected traditional cone-shaped patterns raise several questions about safety. The continuous need for properly engineered medical laser-beam devices, online laser-beam monitoring, and real-time control becomes mandatory in modern surgery. The equipment used in this study was provided by the National Cancer Institute of Milan, Milan, Italy, and by

    Ontological modelling today is applied in many areas of science and technology,including the Semantic Web. The W3C standard OWL defines one of the most important ontology languages based on the semantics of description logics. An alternative is to use rule languages in knowledge modelling, as proposed in the W3C's RIF standard. So far, it has often been unclear how to combine both technologies without sacrificing essential computational properties. This book explains this problem and presents new solutions that have recently been proposed. Extensive introductory chapters provide the necessary

    Telemedicine is a rapidly evolving form of modern information and communication technology used to deliver clinical services and educational activities. The aim of this article is to report and analyze our experience with transatlantic consultation via videoconferencing in pediatric cardiology. In February, 2013, videoconferencing project was launched between a medium-volume pediatric cardiac center in Bratislava, Slovakia and subspecialty experts from a high-volume pediatric cardiac program at The Children's Hospital of Philadelphia (CHOP), USA. During 1.5-2 hours videoconferences, 2-3 patients with similar complex clinical scenarios were presented to CHOP experts. The main goal of the project was consultation on individual patients to validate, alter or radically change clinical management plans. From February, 2013 to January, 2017, 25 videoconferences occurred and 73 cases were discussed. The median patient age was 52 months (range; 1 day-30 years). Forty-six discussed cases were outpatients, 21 patients were in the intensive care unit and 6 patients were discussed post mortem. Thirty-one CHOP experts from different subspecialties participated actively in patient consultations. The most frequent recommendations were related to single ventricle, pulmonary hypertension or heart failure patients and intervention in complex and/or rare cardiac diseases. Specialists from CHOP agreed completely with the original care plan in 16% of cases. In 52% cases, adjustments to original plan were suggested. Radical changes were recommended in 30% of cases. Receiving institution adopted recommendations to the patient care fully in 79% and partially in 13% of patients. Based on our 4-year experience we consider videoconferencing between medium-size pediatric cardiac center and subspecialty experts from a high-volume pediatric cardiac program a suitable form of medical consultations. Videoconferencing assists in clinical decision making for complex patient cases and serves as an

    Full Text Available What is a metaphoric picture of an evil person made of? In a study devoted to the development of the ability to use metaphorical descriptions of humans, the semantic fields of four target metaphors - Human-Swamp, Human-Snake, Human-Knife, and Human-Nettle - were established and compared. Subjects (365 young adults were asked to decipher the metaphors’ meanings. The results were obtained mainly by qualitative analysis, with frequency analysis of clusters containing synonymous meanings. The results indicate that when creating imaginary characteristics of evil people, young adults seem to be more concerned about the possibility of suffering verbal harassment (most commonly: vulgarity, mockery, gossip, jeering than the threat of actual physical assault. The results may prove useful for developmental comparisons.

  9. Task Description Language

    Simmons, Reid; Apfelbaum, David

    2005-01-01

    Task Description Language (TDL) is an extension of the C++ programming language that enables programmers to quickly and easily write complex, concurrent computer programs for controlling real-time autonomous systems, including robots and spacecraft. TDL is based on earlier work (circa 1984 through 1989) on the Task Control Architecture (TCA). TDL provides syntactic support for hierarchical task-level control functions, including task decomposition, synchronization, execution monitoring, and exception handling. A Java-language-based compiler transforms TDL programs into pure C++ code that includes calls to a platform-independent task-control-management (TCM) library. TDL has been used to control and coordinate multiple heterogeneous robots in projects sponsored by NASA and the Defense Advanced Research Projects Agency (DARPA). It has also been used in Brazil to control an autonomous airship and in Canada to control a robotic manipulator.

  10. YUCCA MOUNTAIN SITE DESCRIPTION

    2004-04-16

    The ''Yucca Mountain Site Description'' summarizes, in a single document, the current state of knowledge and understanding of the natural system at Yucca Mountain. It describes the geology; geochemistry; past, present, and projected future climate; regional hydrologic system; and flow and transport within the unsaturated and saturated zones at the site. In addition, it discusses factors affecting radionuclide transport, the effect of thermal loading on the natural system, and tectonic hazards. The ''Yucca Mountain Site Description'' is broad in nature. It summarizes investigations carried out as part of the Yucca Mountain Project since 1988, but it also includes work done at the site in earlier years, as well as studies performed by others. The document has been prepared under the Office of Civilian Radioactive Waste Management quality assurance program for the Yucca Mountain Project. Yucca Mountain is located in Nye County in southern Nevada. The site lies in the north-central part of the Basin and Range physiographic province, within the northernmost subprovince commonly referred to as the Great Basin. The basin and range physiography reflects the extensional tectonic regime that has affected the region during the middle and late Cenozoic Era. Yucca Mountain was initially selected for characterization, in part, because of its thick unsaturated zone, its arid to semiarid climate, and the existence of a rock type that would support excavation of stable openings. In 1987, the United States Congress directed that Yucca Mountain be the only site characterized to evaluate its suitability for development of a geologic repository for high-level radioactive waste and spent nuclear fuel.

    About two-thirds of medical students are distributed among the major metropolitan tertiary teaching hospitals in Queensland, while the remainder are sent to regional hospitals up to 500 km away. The aim of this study was to investigate the feasibility and effectiveness of conducting surgical tutorials via videoconferencing (VC) for medical students undertaking at remote hospitals. Surgical tutorials were offered to final-year medical students at the Royal Children's Hospital (RCH) in Brisbane and shared by VC to students undertaking clinical placement at nine remotely located hospitals in Queensland. We have conducted a retrospective review of service activity, student satisfaction and subject scores from 2008 to 2010. The main outcome measures were VC activity, medical students' satisfaction and student exam results pre- and post-introduction of the surgical tutorial programme. Between March 2009 and November 2010, a total of 57 VC tutorials were conducted during nine rotations for a total of 669 students. Approximately, 35% of students (236) attended tutorials face-to-face at the RCH while the remainder (including those at the Mater Children's Hospital in Brisbane and eight regional sites) participated via VC. A snapshot survey to measure satisfaction of both groups of students showed that overall satisfaction was very high. A total of 299 students completed the paediatrics and child health multiple-station assessment task exam in 2008, 326 in 2009 and 382 in 2010. The pre-intervention (tutorials not delivered by VC) median scores (interquartile range) of surgical and non-surgical questions were 5 (4-6) and 23 (21-25). Post-intervention, surgical scores increased significantly to 6 (5-7) (P < 0.001), while non-surgical scores remained similar at 23 (21-25) (P = 0.64). Our study demonstrates that VC is a feasible and effective method of engaging medical students regardless of their location. VC provides equitable access to medical teaching for medical students undertaking remote clinical placements. © 2012 The Authors.

    A consistent statistical description of kinetics and hydrodynamics of dusty plasma is proposed based on the Zubarev nonequilibrium statistical operator method. For the case of partial dynamics, the nonequilibrium statistical operator and the generalized transport equations for a consistent description of kinetics of dust particles and hydrodynamics of electrons, ions, and neutral atoms are obtained. In the approximation of weakly nonequilibrium process, a spectrum of collective excitations of dusty plasma is investigated in the hydrodynamic limit.

    Full Text Available In the 18th and early 19th centuries, London was a city filled with cabinets of curiosity, 'lusus naturae', and bourgeoning public museums. Most of these institutions publicized their holdings through newspaper advertisements, leaflets, and self-published, descriptive catalogs that were available for purchase on-site and through booksellers. Using Soane’s Museum as a case study, this paper will move beyond historiographical analysis of individual objects in collections catalogs to probe how the museum-produced guidebooks depicted spatial arrangements. Citing examples from the 19th to twenty-first centuries, this paper will examine how the curator-produced descriptions of Soane’s Museum manipulated text and graphics to guide visitors through a constructed narrative, recreated the ephemeral experiences of the museum, and advertise the site’s unparalleled union of painting, sculpture, and architecture to audiences abroad. Soane’s 'Description of the House and Museum, on the North Side of Lincoln‘s Inn-Fields, the Residence of Sir John Soane' (privately printed 1830, 1832; revised 1835 paired spatial narratives with the architectural language of orthographic projection and perspective engravings. His 'Description' set forth an agenda about the museum’s arrangement and established a compositional strategy for subsequent editions of the guidebook, renamed the 'General Description' in the editions printed between 1840 and 1930 then rebranded as the 'New Description' by Summerson in 1955. Through the study of the changing written and visual language published in the guides by the curators of Soane’s Museum, this article will examine the changing character of the visitor experience at the museum and question the form of future editions.

    We have investigated a lattice gas model consisting of repulsive particles following deterministic dynamics. Two versions of the model are studied. In one case we consider a Finite open system in which particles can leave and enter the lattice over the edge. In the other case we use periodic...... in time. We have numerically investigated the power spectrum of the density fluctuations, the lifetime distribution, and the spatial correlation function. We discuss the appropriate Langevin-like diffusion equation which can reproduce our numerical findings. Our conclusion is that the deterministic...... lattice gases are described by a diffusion equation without any bulk noise. The open lattice gas exhibits a crossover behavior as the probability for introducing particles at the edge of the system becomes small. The power spectrum changes from a 1/f to a 1/f2 spectrum.

    We address the changes in Brazilian maritime prophylaxis by studying two cases of immigrant ships arriving at the port of Rio de Janeiro with epidemics onboard. The objective is to understand the etiology, means of prevention and methods used to combat the three diseases subject to international port regulations: yellow fever, bubonic plague and cholera. Until the late nineteenth century, quarantines were one of the main disease prevention practices. In the early twentieth century, microbiology and the concept of vectors in ports sanitation services emerged. Quarantines, which were already being criticized as antiquated and ineffective, were limited to a few cases, and new hygiene methods and technologies began to be applied in port sanitary defense.

    Periprosthetic osteolysis is a well known phenomenon caused by wear particle-induced bone resorption, particularly common and extensively reported in total hip arthroplasty. Its typical radiographic feature is a radiolucent area adjacent to an implant, sometimes associated with a soft tissue mass. Osteolytic changes may be caused by numerous other pathologic processes, including infection, metabolic disease, and neoplasia. Four cases of massive periprosthetic bone destruction associated with a large soft tissue mass around a failed total hip replacement are presented. In three cases, a diagnosis of periprosthetic osteolysis was correctly made and managed by revision surgery. However, in one case angiosarcoma of the ipsilateral hemipelvis went long unrecognized despite aggressive clinical course, requiring hind-quarter amputation and ultimately resulting in the patient's death. Periprosthetic malignancy in the form of either primary sarcoma or metastatic cancer is a very rare yet reported event in the setting of previous hip replacement, likely leading to catastrophic consequences when diagnosis is not established in a timely manner. The differential diagnosis of periprosthetic osteolysis should consider the entire spectrum of conditions that can present with radiolucent changes. Thorough review of patient's history and course of symptoms, along with careful evaluation of standard roentgenograms should be always performed and possibly integrated with imaging modalities such as CT, MRI, and bone scintigraphy in order to increase diagnostic accuracy. If uncertainty remains, biopsy should always be considered to rule out malignancy.

  10. Intervention description is not enough: evidence from an in-depth multiple case study on the untold role and impact of context in randomised controlled trials of seven complex interventions

    Directory of Open Access Journals (Sweden)

    Wells Mary

    2012-06-01

    Full Text Available Abstract Background A number of single case reports have suggested that the context within which intervention studies take place may challenge the assumptions that underpin randomised controlled trials (RCTs. However, the diverse ways in which context may challenge the central tenets of the RCT, and the degree to which this information is known to researchers or subsequently reported, has received much less attention. In this paper, we explore these issues by focusing on seven RCTs of interventions varying in type and degree of complexity, and across diverse contexts. Methods This in-depth multiple case study using interviews, focus groups and documentary analysis was conducted in two phases. In phase one, a RCT of a nurse-led intervention provided a single exploratory case and informed the design, sampling and data collection within the main study. Phase two consisted of a multiple explanatory case study covering a spectrum of trials of different types of complex intervention. A total of eighty-four data sources across the seven trials were accessed. Results We present consistent empirical evidence across all trials to indicate that four key elements of context (personal, organisational, trial and problem context are crucial to understanding how a complex intervention works and to enable both assessments of internal validity and likely generalisability to other settings. The ways in which context challenged trial operation was often complex, idiosyncratic, and subtle; often falling outside of current trial reporting formats. However, information on such issues appeared to be available via first hand ‘insider accounts’ of each trial suggesting that improved reporting on the role of context is possible. Conclusions Sufficient detail about context needs to be understood and reported in RCTs of complex interventions, in order for the transferability of complex interventions to be assessed. Improved reporting formats that require and encourage

  12. Tarsal tetramery and extreme size reduction in Anillini (Coleoptera, Carabidae, Trechinae): the case of Typhlocharis Dieck, 1869; description of three new species and definition of a new intra-generic species group.

    Pérez-González, Sergio; Zaballos, Juan P

    2013-01-01

    Tarsal tetramery is a rare condition within Carabidae, only found in some members of the endogean tribe Anillini and some cases of Gehringiini. Reduction of tarsomere numbers is also reported in endogean members of other families (e.g. Curculionidae or Staphylinidae). Recent fieldwork in southwestern Spain provided specimens of three new species of the endogean Anillini Typhlocharis Dieck, 1869: T. baeturica n.sp., T. scrofa n.sp. and T. tetramera n.sp. The new species share extreme body size reduction (less than 1.1 mm), a gula partially fused to the cephalic capsule, with diffuse lateral sutures, and four tarsomeres in all the legs. Tarsal tetramery is recorded for the first time within the genus Typhlocharis and it is contrasted with the described cases in Anillini. Typhlocharis scrofa n.sp. and T. tetramera n.sp. have club-shaped gonocoxites, reminiscent of the unguiform-like morphology observed in T. quadridentata (Coiffait, 1969), supporting the hypothesis of a transitional evolution of the shape of gonocoxites. The structure of the gula is studied within the genus and includes wide, narrow and diffuse morphologies. The implications of these features and data from the new species enable us to propose a reorganization of the systematics of the genus, creating and defining a new group of species, quadridentata group. An identification key for this species group is included. The new species provides more data on syntopic species and abundance rates, brief insights on the ecology of the genus.

    Full Text Available É apresentado um caso clínico de paciente portador de paralisia facial periférica com comprometimento de toda a hemiface direita. Durante a investigação clínica, esperava-se que o comprometimento topográfico do nervo facial se desse a partir de sua emergência na ponte. Após exames de imagem, evidenciou-se lesão expansiva no tronco cerebral. Deste modo, a classificação de paralisia facial como periférica ou central não atende a este caso. O uso de uma classificação utilizando os núcleos do nervo facial como referência pode ser mais adequado na investigação clínica da paralisia facial.It is presented a clinical case of a patient with a peripheral facial paralysis with hemifacial compromise. During the clinical investigation it was expected that the topographic compromise of the facial nerve would arise out of the emergence of the nerve from the pons. After some image examinations, an expansive brain trunk lesion was evidenced. Thus, the classification of facial paralysis - either peripheral or central - is not applicable to this case. The use of a classification having the facial nerve nucleus as reference could be more adequate in the clinical investigation of the paralysis.

    Full Text Available La miocardiopatía no-compacta es una anomalía estructural del corazón, que se caracteriza por múltiples trabeculaciones en el miocardio ventricular, las cuales hacen continuidad con la cavidad, sin evidencia de comunicación con las arterias epicárdicas. Además, se acompañan de recesos ínter-trabeculares profundos. El diagnóstico se basa en demostrar trabéculas profundas en la pared ventricular en continuidad con la cavidad. Se describen los casos de dos pacientes adultos a quienes se les diagnosticó miocardiopatía con base en los hallazgos del ecocardiograma. El primero fue un hombre de 83 años de edad con áreas de hipertrofia y falta de compactación, con grandes trabéculas en los segmentos apicales de la pared inferior y el septum. El segundo era una mujer de 58 años de edad con hipertrofia y falta de compactación en los segmentos apicales de las paredes inferior, anterior y lateral. En ambos casos fue evidente la utilidad del eco-realzador de microburbujas de perflutren por lograr la opacificación de las trabéculas en las áreas de hipertrofia. En conclusión la miocardiopatía no-compacta se puede presentar en adultos mayores. El ecocardiograma con el uso de eco-realzador, es útil para su diagnóstico.Non-compact myocardiopathy is a structural heart anomaly characterized by multiple trabeculations in ventricular myocardium that make continuity with the cavity without evidence of communication with epicardial arteries.

  1. Vector description of nonlinear magnetization

    2001-06-01

    The definition of the nonlinear magnetization, which is usually applied in investigating superconductors is discussed in this paper. The nonlinear magnetization of the superconductor, as the response to the alternating magnetic field, is a periodic time function and is determined by the sequence of complex numbers {chi}{sub n}={chi}{sub n}'+i{chi}{sub n}'', n=1,2,3,.... The sequence {chi}{sub n} is named harmonic susceptibility. Finding some limits in this definition we propose a new description, substituting the complex sequence {chi}{sub n} with the sequence of real covariant vectors. Such a definition of the nonlinear magnetization, allows to determine function M(t) of an investigated system for an arbitrary initial phase {theta}{sub o} of the inducing magnetic field H{sub ac}=h{sub ac} sin({omega}t+{theta}{sub o}). Vector description, in our opinion, is superior to the complex one in respect of explicitness, simplicity, and universality. Circular diagrams are used to illustrate the new vector description. We also show how the vectors of the harmonic susceptibility can be derived from both numeric calculations and experimental data.

  5. Multiple descriptions for packetized predictive control

    Østergaard, Jan; Quevedo, Daniel

    2016-01-01

    In this paper, we propose to use multiple descriptions (MDs) to achieve a high degree of robustness towards random packet delays and erasures in networked control systems. In particular, we consider the scenario, where a data-rate limited channel is located between the controller and the plant...... input. This forward channel also introduces random delays and dropouts. The feedback channel from the plant output to the controller is assumed noiseless. We show how to design MDs for packetized predicted control (PPC) in order to enhance the robustness. In the proposed scheme, a quantized control...... be reliably reconstructed at the plant side. For the particular case of LTI plant models and i.i.d. channels, we show that the overall system forms a Markov jump linear system. We provide conditions for mean square stability and derive upper bounds on the operational bit rate of the quantizer to guarantee...

  6. Polynomial description of inhomogeneous topological superconducting wires

    Science.gov (United States)

    Pérez, Marcos; Martínez, Gerardo

    2017-11-01

    We present the universal features of the topological invariant for p-wave superconducting wires after the inclusion of spatial inhomogeneities. Three classes of distributed potentials are studied, a single-defect, a commensurate and an incommensurate model, using periodic site modulations. An analytic polynomial description is achieved by splitting the topological invariant into two parts; one part depends on the chemical potential and the other does not. For the homogeneous case, an elliptical region is found where the topological invariant oscillates. The zeros of these oscillations occur at points where the fermion parity switches for finite wires. The increase of these oscillations with the inhomogeneity strength leads to new isolated non-topological phases. We characterize these new phases according to each class of spatial distributions. Such phases could also be observed in the XY model, to which our model is dual.

  7. Temporary fusionless posterior occipitocervical fixation for a proximal junctional type II odontoid fracture after previous C2-pelvis fusion: case report, description of a new surgical technique, and review of the literature.

    Axial fractures in patients with a previous C2-pelvis posterior instrumented fusion are rare and may be challenging to manage. Motion preservation in the axial spine for these patients is important, as the C1-2 and Occipit-C1 joints are their only remaining mobile spinal segments. In this unique report, we present for the first time the use of a fusionless occipitocervical operation for the treatment of a type II odontoid fracture and unilateral C2 pars fracture adjacent to a previous C2-pelvis posterior instrumented fusion. Case report. Three years after proximal extension of a T3-pelvis posterior instrumented fusion to C2, the patient sustained a displaced odontoid fracture and unilateral C2 pars fracture after a mechanical fall. She underwent fracture stabilization with extension of instrumentation to the occiput. No attempt at fusion was performed. Post-operatively, she was distraught by severely limited neck range of motion, which was reflected in worsening of health-related quality of life (HRQoL) scores. The fracture healed uneventfully after which the instrumentation from the occiput and C1 were removed, which resulted in improvement of neck range of motion. Two years post-operatively, HRQoL scores showed minimal neck disability (NDI 12), no neck or arm pain (VAS 0), and outstanding general health (EQ-5D 85 out of 100, SF-36 PCS 35.3, SF-36 MCS 41.1). In this one patient, instrumentation without fusion allowed for successful and timely union of a displaced odontoid fracture in a patient with a previous C2-pelvis fusion. Axial range of motion was preserved after instrumentation removal.

  8. Autosomal dominant transmission of a Goldenhar-like syndrome: Description of a family and report of a sporadic case with a de novo 4p16;8q24.11 translocation

    1994-09-01

    We report vertical transmission of a Goldenhar-like syndrome, including a father and 5 offspring, with male-to-male transmission and variable features that include hearing loss, ear anomalies (microtia, ear tags/pits), branchial cysts, ocular/periocular dermoids, micrognathia and seizures. We also report an individual with an apparently balanced de novo reciprocal translocation with breakpoints at 4p16 and 8q24.11. This individual has unilateral microtia, an epibulbar dermoid cyst, facial asymmetry with a small chin, and seizures. In addition to these features resembling those seen in the family above, she has multiple exostoses, supraventricular tachycardia, hypoglycemia and mild developmental delays. Based on the overlap in physical findings between this family and the individual with the de novo reciprocal translocation, linkage studies on the family were intiated. Preliminary results exclude linkage to HOX 7 at 4p16.1 but not to 8q. The brancho-oto-renal syndrome has previously been localized to 8q11-8q13, but linkage to this region appears unlikely. Although most cases of Goldenhar syndrome appear to be sporadic, there are a few reports of autosomal dominant inheritance (MIM No. 164210). One such family showed vertical transmission of dermoids, ear anomalies, hearing loss, micrognathia and vertebral anomalies, but no branchial cysts. Another family showed sensorineural deafness, preauricular pits, and branchial fistulae, and other families reveal ear anomalies, branchial fistulas, and hearing loss. These latter families appear to lack ocular/periocular dermoids, and appear to be affected by a different disorder (MIM No. 125100). Further clinical delineation of such families, combined with genetic linkage analysis, should help to sort out this heterogeneity.

    A. J. Lucendo Villarín

    2005-04-01

    Full Text Available Background: eosinophilic esophagitis is a rare condition mainly affecting children, although the number of cases reported in adults is on the increase. It is characterized by intense infiltration of eosinophilic leukocytes in the esophageal mucosa, without involvement of other sections of the alimentary canal. Material and methods: over the past year, following the performance of endoscopies and biopsies, our service identified nine patients who were diagnosed with suffering from this disorder. Each patient sought medical help for episodes of long-term, self-limited dysphagia or food impaction in the alimentary canal. Results: endoscopy revealed esophageal stenosis in the form of simultaneous contraction rings or regular stenosis. In six cases, the manometric study showed a nonspecific motor disorder of severe intensity affecting the esophageal body, and another patient had a disorder characterized by the presence of simultaneous waves and secondary peristaltic waves in the three thirds of the organ. These disorders are presumably due to eosinophilic infiltration of the muscular layer or ganglionar cells of the esophagus, and account for symptoms in these patients. Although the etiopathogenesis of this illness is uncertain, it is clearly an immunoallergic manifestation. Conclusions: as the number of diagnosed cases is on the increase, eosinophilic esophagitis is in adults a specific entity within the differential diagnosis of dysphagia in young males with a history of allergies. Eosiniphilic esophagitis responds in a different number of ways to therapies used. We successfully used fluticasone propionate, a synthetic corticoid applied topically, which proved to be efficient in the treatment of this illness by acting on the pathophysiological basis of the process. It does not have any adverse effects, thus offering advantages over other therapies such as systematic corticoids or endoscopic dilations.Introducción: la esofagitis eosinofílica es

    We investigate a fluid description of inflationary cosmology. It is shown that the three observables of the inflationary universe: the spectral index of the curvature perturbations, the tensor-to-scalar ratio of the density perturbations, and the running of the spectral index, can be compatible with the Planck analysis. In addition, we reconstruct the equation of state (EoS) for a fluid from the spectral index of the curvature perturbations consistent with the Planck results. We explicitly demonstrate that the universe can gracefully exit from inflation in the reconstructed fluid models. Furthermore, we explore the singular inflation for a fluid model.

  15. Addressing the Language Description Deficit

    Directory of Open Access Journals (Sweden)

    M. Ali Bolgiin

    2010-01-01

    Full Text Available Well-described language features are key to successful teaching and learning, especially for achieving advanced levels of proficiency. Other measures, such as simply increasing the number of reading and listening passages in a language program alone are not enough to bring the student to a higher level in a given skill. In fact, even being present in the target culture does not suffice. Angelelli and Degueldre (2002 argue that at advanced levels, even spending time in a country where the language is spoken is not necessarily sufficient for learners: "They do not need just exposure; they need answers to questions and explanations that they can rarely get by simply being immersed in a language/ culture." Less commonly taught languages (LCTLs lack descriptions that have such answers and explanations (cf. Fotos, 2002. It is argued in this paper that corpuslinguistic analyses help to provide actual usage-based, rather than intuition-based, descriptions and explanations of language features. Such approach is illustrated through English and Turkish examples.

    2016-01-01

    Full Text Available Web Services Choreography Description Language lacks a formal system to accurately express the semantics of service behaviors and verify the correctness of a service choreography model. The paper presents a new approach of choreography model verification based on Description Logic. A metamodel of service choreography is built to provide a conceptual framework to capture the formal syntax and semantics of service choreography. Based on the framework, a set of rules and constraints are defined in Description Logic for choreography model verification. To automate model verification, the UML-based service choreography model will be transformed, by the given algorithms, into the DL-based ontology, and thus the model properties can be verified by reasoning through the ontology with the help of a popular DL reasoner. A case study is given to demonstrate applicability of the method. Furthermore, the work will be compared with other related researches.

  19. Quantum description of radiative decay in optical cavities

    Science.gov (United States)

    Oppermann, J.; Straubel, J.; Słowik, K.; Rockstuhl, C.

    2018-01-01

    We derive the quantum mechanical description of light-matter interactions in optical cavities characterized solely by radiative decay. Unique to radiative decay is the conservation of photon number and coherence, in stark contrast to absorptive losses. This prohibits the description of such cavities by traditional means, e.g., coupling it to a bath of harmonic oscillators into which energy is dissipated. Here, we propose a description of cavities with radiative decay by introducing cavity and noise operators in terms of scattering modes. A multimode input-output formalism to predict measurable far field quantities arises naturally. We apply our general model to the special case of the single excitation regime. We find dynamics reminiscent of the dissipative Jaynes-Cummings model, but with vanishing backaction and a rich temporal and spectral structure of the output modes.

A prototype of the system is currently under development in collaboration with the Mushroom Observer website. It allows users to propose new names and descriptions for fungi, provide feedback on those proposals, and ultimately have them formally approved. It relies on SPARQL queries and semantic reasoning for data management. This effort will offer the mycology community a knowledge base of fungal observational features and a tool for identifying fungal observations. It will also serve as an operational specification of how the Semantic Vernacular System can be used in practice in one scientific community (in this case mycology).

  2. Do children prefer mentalistic descriptions?

    Science.gov (United States)

    Dore, Rebecca A; Lillard, Angeline S

    2014-01-01

    Against a long tradition of childhood realism (Piaget, 1929), A. S. Lillard and J. H. Flavell (1990) found that 3-year-olds prefer to characterize people by their mental states (beliefs, desires, emotions) than by their visible behaviors. In this exploratory study, we extend this finding to a new cohort of 3-year-olds, examine how these preferences change from 3-4 years, and explore relationships with theory of mind and parental mind-mindedness. The results showed a developmental change and a possible cohort difference: at 3 years, children in the sample preferred behavioral descriptions, although by 4 years of age, they preferred mentalistic ones. Interestingly, mentalistic preferences were unrelated to theory of mind or parental mind-mindedness, concurrently or over time. Perspective-taking skills at 3 years, however, predicted an increase in mentalistic responses from 3 years to 4 years. Possible explanations for each finding are discussed.

  5. Theory buried under heavy description

    2010-12-01

    Full Text Available In journalism when a reporter puts the main news or point of the story deep down in the text, we say she’s buried the lead, the lead being the main point of the story and usually the first paragraph. In Children in Genocide: extreme traumatization and affect regulation, psychoanalyst Suzanne Kaplan buries her theory. Her study of the after effects of trauma among Holocaust survivors who were children during their persecution and survivors of atrocities during the Rwandan atrocities of the 1990s, is filled with highly descriptive material from the many interviews that serve as data. An interesting grounded theory is peeking out from under all the disciplinary discourse and historical background one must read through to get to what grounded theory readers will consider the juicy parts: concepts on affect regulation in trauma survivors.

    2014-01-01

    The High Luminosity LHC (HL-LHC) is a novel configuration of the Large Hadron Collider, aiming at increasing the luminosity by a factor five or more above the nominal LHC design, to allow increasing the integrated luminosity, in the high luminosity experiments ATLAS and CMS, from the 300 fb-1 of the LHC original design up to 3000 fb-1 or more. This paper contains a short description of the main machine parameters and of the main equipment that need to be developed and installed. The preliminary cost evaluation and the time plan are presented, too. Finally, the international collaboration that is supporting the project, the governance and the project structure are discussed, too.

    This paper presents basic methods of reversible circuit description. To design reversible circuit a set of gates has to be chosen. Most popular libraries are composed of three types of gates so called CNT gates (Control, NOT and Toffoli). The gate indexing method presented in this paper is based on the CNT gates set. It introduces a uniform indexing of the gates used during synthesis process of reversible circuits. The paper is organized as follows. Section 1 recalls basic concepts of reversible logic. In Section 2 and 3 a graphical representation of the reversible gates and circuits is described. Section 4 describes proposed uniform NCT gates indexing. The presented gate indexing method provides gate numbering scheme independent of lines number of the designed circuit. The solution for a circuit consisting of smaller number of lines is a subset of solution for a larger circuit.

  8. Simpevarp - site descriptive model version 0

    2002-11-01

    During 2002, SKB is starting detailed investigations at two potential sites for a deep repository in the Precambrian rocks of the Fennoscandian Shield. The present report concerns one of those sites, Simpevarp, which lies in the municipality of Oskarshamn, on the southeast coast of Sweden, about 250 kilometres south of Stockholm. The site description will have two main components: a written synthesis of the site, summarising the current state of knowledge, as documented in the databases containing the primary data from the site investigations, and one or several site descriptive models, in which the collected information is interpreted and presented in a form which can be used in numerical models for rock engineering, environmental impact and long-term safety assessments. SKB maintains two main databases at the present time, a site characterisation database called SICADA and a geographic information system called SKB GIS. The site descriptive model will be developed and presented with the aid of the SKB GIS capabilities, and with SKBs Rock Visualisation System (RVS), which is also linked to SICADA. The version 0 model forms an important framework for subsequent model versions, which are developed successively, as new information from the site investigations becomes available. Version 0 is developed out of the information available at the start of the site investigation. In the case of Simpevarp, this is essentially the information which was compiled for the Oskarshamn feasibility study, which led to the choice of that area as a favourable object for further study, together with information collected since its completion. This information, with the exception of the extensive data base from the nearby Aespoe Hard Rock Laboratory, is mainly 2D in nature (surface data), and is general and regional, rather than site-specific, in content. Against this background, the present report consists of the following components: an overview of the present content of the databases

    Contreras, Mónica Yicette Sánchez; Vargas, Paula Alejandra Osorio; Ramos, Lucero Rengifo; Velandia, Rafael Alarcón

    The authors describe a family group studied by the Centro de Biología Molecular y Biotecnología, and the Clínica de la Memoria, las Demencias y el Envejecimiento (Universidad Tecnológica de Pereira, Colombia), and evaluate the association of depressive symptoms with Alzheimer's disease (AD). This family presented a hereditary pattern for AD characterized by an early onset of dementia symptoms, a long preclinical depressive course, and, once the first symptoms of dementia appeared, a rapid progression to severe cognitive function impairment. The authors found a high prevalence of depressive symptoms in this family and propose that the symptoms could be an important risk factor for developing AD in the presence of other risk factors such as the APOE E4 allele.

    2012-11-01

    Full Text Available Ostrich (Struthio camelus is a bird characterized by its large size, it can achieve 2.8m in height and weight over 150kg. It has an Egyptian origin and then spread throughout Africa. Commercial breeding began about 150 years ago, with the domestication of native animals from South Africa, country which holds the first position in meat supply. Several musculoskeletal diseases were observed in fast-growing birds, such as ostrich. High body weight, associated to a developing bone structure, is indicated as the main cause of disorders of the locomotor system. In this study, an adult male specimen was used, from an ostrich production farm located at the town of Paranatama, Pernambuco, Brazil. After removing soft tissues, bone measurements were performed with caliper and tape measure, and each bone was photographed for documentation and described. This study aims to contribute to increase knowledge on the ostrich skeletal system, as well as provide a basis for muscle development, one of the main targets of commercial exploitation with regard to this species.

    Full Text Available Perineurioma is a rare entity, it is a benign peripheral nerve sheath tumor entirely composed of perineurial cells. A 62-year-old male patient was admitted to our hospital, suffering from scrotal and pelvic pain combined with a severe and continuous pain in his right thigh. A transrectal ultrasound revealed a periprostatic oval lesion of about 5 cm in maximum diameter. A sovrapubic laparotomy was performed with a complete tumor excision. The morphological and immunohistochemical data were most consistent with the diagnosis of perineurioma.

    MELAS syndrome -myopathy, encephalopathy, lactic acidosis and stroke-like episodes- is a maternally-inherited mitochondrial cytopathy related to several mitochondrial DNA mutations, with the A3243G mutation in tRNALeu gene being the most frequent of them. Apart from its typical symptomatology, patients usually exhibit a maternally-inherited history of neurosensory deafness and insulin-dependent type 2 diabetes mellitus (T2DM). Recent studies have shown that few patients carrying a A3243G mutation also suffer from renal dysfunction, usually in form of focal segmental glomerulosclerosis (FSGS). In this study we examine kidney involvement in 2 unrelated patients with a A3243G mutation by genetic testing. Both have a maternally-inherited neurosensory deafness and insulin-dependent T2DM. A renal biopsy was performed in both patients. One patient developed nephrotic proteinuria and renal insufficiency, with FSGS findings being observed in the kidney biopsy, whereas the other suffered from mild proteinuria and renal insufficiency, with non-specific glomerular changes. The presence of FSGS or other kidney involvement accompanied by hereditary neurosensory deafness and T2DM could be suggestive of a A3243G tRNALeu mutation and should prompt a genetic testing and an evaluation of potential extrarenal involvement.

    2016-12-01

    Full Text Available Background: The relevance of our research, above all, is theoretically motivated by the development of extraordinary scientific and practical interest in the possibilities of language processing of huge amount of data generated by people in everyday professional and personal life in the electronic forms of communication (e-mail, sms, voice, audio and video blogs, social networks, etc.. Purpose: The purpose of the article is to describe the theoretical and practical framework of the project "Communicative-pragmatic and discourse-grammatical lingvopersonology: structuring linguistic identity and computer modeling". The description of key techniques is given, such as machine learning for language modeling, speech synthesis, handwriting simulation. Results: Lingvopersonology developed some great theoretical foundations, its methods, tools, and significant achievements let us predict that the newest promising trend is a linguistic identity modeling by means of information technology, including language. We see three aspects of the modeling: 1 modeling the semantic level of linguistic identity – by means of the use of corpus linguistics; 2 sound level formal modeling of linguistic identity – with the help of speech synthesis; 3 formal graphic level modeling of linguistic identity – with the help of image synthesis (handwriting. For the first case, we suppose to use machine learning technics and vector-space (word2vec algorithm for textual speech modeling. Hybrid CUTE method for personality speech modeling will be applied to the second case. Finally, trained with the person handwriting images neural network can be an instrument for the last case. Discussion: The project "Communicative-pragmatic, discourse, and grammatical lingvopersonology: structuring linguistic identity and computer modeling", which is implementing by the Department of General and Applied Linguistics and Slavonic philology, selected a task to model Yuriy Shevelyov (Sherekh

  19. XML Translator for Interface Descriptions

    Science.gov (United States)

    Boroson, Elizabeth R.

    2009-01-01

    A computer program defines an XML schema for specifying the interface to a generic FPGA from the perspective of software that will interact with the device. This XML interface description is then translated into header files for C, Verilog, and VHDL. User interface definition input is checked via both the provided XML schema and the translator module to ensure consistency and accuracy. Currently, programming used on both sides of an interface is inconsistent. This makes it hard to find and fix errors. By using a common schema, both sides are forced to use the same structure by using the same framework and toolset. This makes for easy identification of problems, which leads to the ability to formulate a solution. The toolset contains constants that allow a programmer to use each register, and to access each field in the register. Once programming is complete, the translator is run as part of the make process, which ensures that whenever an interface is changed, all of the code that uses the header files describing it is recompiled.

  20. Action description using point clouds

    Liu, Wenping; Jiang, Yongfeng; Wang, Haili; Zhang, Liang

    2017-06-01

    An action description method named as Motion History Point Cloud (MHPC) is proposed in this paper. MHPC compresses an action into a three-dimensional point cloud in which depth information is required. In MHPC, the spatial coordinate channels are used to record the motion foreground, and the color channels are used to record the temporal variation. Due to containing depth information, MHPC can depict an action more meticulous than Motion History Image (MHI). MHPC can serve as a pre-processed input for various classification methods, such as Bag of Words and Deep Learning. An action recognition scheme is provided as an application example of MHPC. In this scheme, Harris3D detector and Fast Point Feature Histogram (FPFH) are used to extract and describe features from MHPC. Then, Bag of Words and multiple classification Support Vector Machine (SVM) are used to do action recognition. The experiments show that rich features can be extracted from MHPC to support the subsequent action recognition even after downsampling. The feasibility and effectiveness of MHPC are also verified by comparing the above scheme with two similar methods.

    2015-09-01

    To describe a series of cases of basal cell carcinomas of the eyelid. A descriptive and retrospective study was conducted by reviewing the medical outcome, histopathological history, and photographic images of 200 patients with basal cell eyelid carcinomas. All were treated in the Herzog Carl Theodor Eye Hospital in Munich, Germany, between 2000 and 2013. In the present study, it was found that females are more affected than males. The mean age of presentation of the tumor occurred at the age of 70 years. In 50% of the cases the tumor was found on the lower lid, especially medially from the center of the lid. The lid margin was involved in 47% of all tumors. The mean diameter was 9.2mm. The recurrence rate after surgery with histologically clear resection margins was 5%. There was a significant relationship between tumor diameter and age. As tumors where located farther away from medial and closer to the lid margin, they became larger. There is a predominance of women affected by this tumor. This may be related to the fact that the sample was taken from those attending an oculoplastic surgery clinic, where there are generally more women than men attending. The formation of basal cell carcinomas increases with age. The infrequent involvement of the upper lid could be explained by the protection of the the eyebrow. The frequent involvement of the lower lid may be due to the light reflection (total reflection) by the cornea on the lower lid margin. Also chemical and physical effects of the tears may be more harmful on the lower lid. Patients tend to ask for medical help when they are females, younger, when the tumor is closer to the medial canthus or when the tumor is away from the lid margin.

    2014-08-01

    Giardiasis, caused by the intestinal protozoan parasite Giardia intestinalis (synonyms: G. lamblia, G. duodenalis), is one of the most frequent parasites to infect the Scottish population. Transmission of the infective cysts in faecal matter is commonly via food and/or water. Giardia is subdivided into assemblages, where clinical and epidemiological differences have been described between assemblages A and B. This snapshot descriptive epidemiological study examines 30 positive cases of Giardia of which 72% (n = 21) were shown to be assemblage A, 14% (n = 4) assemblage B and 10% (n = 3) mixed assemblages (A and B). There was a 2:3 female:male ratio of affected individuals with foreign travel recorded in 22 of these cases. The commonest symptom was diarrhoea which was reported in 80% of cases followed by tiredness. Five cases required hospitalization emphasizing the importance of gaining a greater understanding of how Giardia assemblages influence clinical outcomes to assist in formulating guidelines to manage potential Giardia outbreaks.

  5. Descriptive Epidemiology of Cervical Dystonia

    Directory of Open Access Journals (Sweden)

    Giovanni Defazio

    2013-11-01

    Full Text Available Background: Cervical dystonia (CD, the most common form of adult‐onset focal dystonia, has a heterogeneous clinical presentation with variable clinical features, leading to difficulties and delays in diagnosis. Owing to the lack of reviews specifically focusing on the frequency of primary CD in the general population, we performed a systematic literature search to examine its prevalence/incidence and analyze methodological differences among studies. Methods: We performed a systematic literature search to examine the prevalence data of primary focal CD. Sixteen articles met our methodological criteria. Because the reported prevalence estimates were found to vary widely across studies, we analyzed methodological differences and other factors to determine whether true differences exist in prevalence rates among geographic areas (and by gender and age distributions, as well as to facilitate recommendations for future studies.Results: Prevalence estimates ranged from 20–4,100 cases/million. Generally, studies that relied on service‐based and record‐linkage system data likely underestimated the prevalence of CD, whereas population‐based studies suffered from over‐ascertainment. The more methodologically robust studies yielded a range of estimates of 28–183 cases/million. Despite the varying prevalence estimates, an approximate 2:1 female:male ratio was consistent among many studies. Three studies estimated incidence, ranging from 8–12 cases/million person‐years. Discussion: Although several studies have attempted to estimate the prevalence and incidence of CD, there is a need for additional well‐designed epidemiological studies on primary CD that include large populations; use defined CD diagnostic criteria; and stratify for factors such as age, gender, and ethnicity.

  6. Description of moving plasma blob

    Rys, Stanisław

    Physical models describing the structure close to the radio source's core have to account for strong forces existing in the vicinity of the black hole. Therefore, describing the motion of an outflow from the core, even in the simplest case, we should take into account a deceleration factor. Using special relativity formulae and including the orientation of the outflow direction with respect to the observer as one of the parameters, we have developed a model of an outflow close to the core. Here, a simple analytical model of decelerated motion is described and a few morphological properties of a radio source structure close to the core are discussed.

  7. Emplacement Drift System Description Document

    Energy Technology Data Exchange (ETDEWEB)

    Eric Loros

    2001-07-31

    The Emplacement Drift System is part of the Engineered Barrier System and provides the interface between the various waste package (WP) systems and the Ground Control System. In conjunction with the various WPs, the Emplacement Drift System limits the release and transport of radionuclides from the WP to the Natural Barrier following waste emplacement. Collectively, the Emplacement Drift System consists of the structural support hardware (emplacement drift invert and WP emplacement pallet) and any performance-enhancing barriers (drip shields and invert ballast) installed or placed in the emplacement drifts. The Emplacement Drift System is entirely located within the emplacement drifts in the subsurface portion of the Monitored Geologic Repository (MGR); specifically, it is physically bounded by the Subsurface Facility System, the Ground Support System, and the Natural Barrier. The Emplacement Drift System supports the key MGR functions of limiting radionuclide release to the Natural Barrier, minimizing the likelihood of a criticality external to the WPs, limiting natural and induced environmental effects, and providing WP support. The Emplacement Drift System limits radionuclide release to the Natural Barrier by controlling the movement of radionuclides within the emplacement drift and to the Natural Barrier, and by limiting water contact with the WPs. The Emplacement Drift System provides physical support and barriers for emplaced WPs that reduce water contact. The Emplacement Drift WP spacing supports the thermal loading performance by complimenting drift layout and orientation as described in the system description document for the Subsurface Facility System. The Emplacement Drift System supports the WP and also provides an environment that aids in enhancing WP confinement performance. As part of the Engineered Barrier System, the Emplacement Drift System interfaces with the WP systems. The Emplacement Drift System also interfaces with the Natural Barrier

  12. Audio Description as a Pedagogical Tool

    Directory of Open Access Journals (Sweden)

    Georgina Kleege

    2015-05-01

    Full Text Available Audio description is the process of translating visual information into words for people who are blind or have low vision. Typically such description has focused on films, museum exhibitions, images and video on the internet, and live theater. Because it allows people with visual impairments to experience a variety of cultural and educational texts that would otherwise be inaccessible, audio description is a mandated aspect of disability inclusion, although it remains markedly underdeveloped and underutilized in our classrooms and in society in general. Along with increasing awareness of disability, audio description pushes students to practice close reading of visual material, deepen their analysis, and engage in critical discussions around the methodology, standards and values, language, and role of interpretation in a variety of academic disciplines. We outline a few pedagogical interventions that can be customized to different contexts to develop students' writing and critical thinking skills through guided description of visual material.

    Peleg, Mor; Gutnik, Lily A; Snow, Vincenza; Patel, Vimla L

    2006-04-01

    Errors in clinical practice guidelines may translate into errors in real-world clinical practice. The best way to eliminate these errors is to understand how they are generated, thus enabling the future development of methods to catch errors made in creating the guideline before publication. We examined the process by which a medical expert from the American College of Physicians (ACP) created clinical algorithms from narrative guidelines, as a case study. We studied this process by looking at intermediate versions produced during the algorithm creation. We identified and analyzed errors that were generated at each stage, categorized them using Knuth's classification scheme, and studied patterns of errors that were made over the set of algorithm versions that were created. We then assessed possible explanations for the sources of these errors and provided recommendations for reducing the number of errors, based on cognitive theory and on experience drawn from software engineering methodologies.

    2016-01-01

    Universal design (UD) has gained global significance and is in the process of institutionalisation in the Nordic Region. This is despite an urgent necessity for developing the theoretical basis and practical applicability of UD. Reflecting this need for furthering the comprehensive understanding of spatial implication of UD, this paper aims to contribute for articulating a means to assess the quality of UD in architecture. Drawing upon numerous cases from research conducted at the Danish Building Research Institute, the paper focuses on sensory aspects of spatial quality, and discusses as well as reflects an applied method for producing the qualitative description of selected buildings that embody UD through creative solutions. The qualitative description of collected examples appears to be effective in delineating sensory aspects of spatial experience; however the systematic development of assessment criteria is essential in order to support students and designers to make responsible decisions in shaping built environments that are accessible and inclusive but also enjoyable.

  15. Statistical descriptions of nonlinear systems at the onset of chaos

    Science.gov (United States)

    Coraddu, Massimo; Lissia, Marcello; Tonelli, Roberto

    2006-06-01

    Ensemble of initial conditions for nonlinear maps can be described in terms of entropy. This ensemble entropy shows an asymptotic linear growth with rate K. The rate K matches the logarithm of the corresponding asymptotic sensitivity to initial conditions λ. The statistical formalism and the equality K=λ can be extended to weakly chaotic systems by suitable and corresponding generalizations of the logarithm and of the entropy. Using the logistic map as a test case we consider a wide class of deformed statistical description which includes Tsallis, Abe and Kaniadakis proposals. The physical criterion of finite-entropy growth K strongly restricts the suitable entropies. We study how large is the region in parameter space where the generalized description is useful.

Material and Methods: We evaluated archive records of patients disgnosed with deep vein thrombosis (DVT and pulmonary thromboembolism (PTE between 2000 an 2005. Age average of patients was advanced and most of them were women. They had DVT, PTE, DVT and PTE respectively. Most common diagnostic method used for PTE was computed thomogrphy (CT, for DVT was ultrasonography (USG. VTE was diagnosed most frequently in emergency services and policlinics. Most common chronic risk factors for VTE were cancer, heart failure/romathismal cardiac disease, hyperlipidemia/atherosclerosis and obesity. Risk factors spesific to the attacks (or temporary were immobilization, surgery, pregnancy, taking oral contraseptive drugs and trauma. Results: In patients investigated for hemostatic risk factors, Factor V Leiden, Prothrombin 20210 A , and MTHFR mutations were found respectively. Symptoms and findings of patients admitted with PTE were dyspnea-tachipnea, tachycardia, palpitation, pleural pain, caugh, fever, anginal pain, hemopthysis, diaphoresis and wheezing . Echocardiography gave positive results for the most of PTE cases. D-dimer test was found high sensitive. Treatments during accute attacks were low moleculer weight heparin (LMWH, standart heparin, thrombolytic therapy, surgery, aspirine and vena cava inferior filter placement. Acute term complications were death, bleeding and heparin induced thrombocytopenia. Conclusion: This retrospective study reflects the approach of VTE diagnosis and treatment in a reference hospital and it may guide for prospective studies. [Cukurova Med J 2013; 38(4.000: 610-616

    We analyze the characteristic features of traffic breakdown. To describe this phenomenon we apply the probabilistic model regarding the jam emergence as the formation of a large car cluster on a highway. In these terms, the breakdown occurs through the formation of a certain critical nucleus in the metastable vehicle flow, which enables us to confine ourselves to one cluster model. We assume that, first, the growth of the car cluster is governed by attachment of cars to the cluster whose rate is mainly determined by the mean headway distance between the car in the vehicle flow and, maybe, also by the headway distance in the cluster. Second, the cluster dissolution is determined by the car escape from the cluster whose rate depends on the cluster size directly. The latter is justified using the available experimental data for the correlation properties of the synchronized mode. We write the appropriate master equation converted then into the Fokker-Planck equation for the cluster distribution function and analyze the formation of the critical car cluster due to the climb over a certain potential barrier. The further cluster growth irreversibly causes jam formation. Numerical estimates of the obtained characteristics and the experimental data of the traffic breakdown are compared. In particular, we draw a conclusion that the characteristic intrinsic time scale of the breakdown phenomenon should be about 1 min and explain the case why the traffic volume interval inside which traffic breakdown is observed is sufficiently wide.

  19. Converting Taxonomic Descriptions to New Digital Formats

    2008-01-01

    Full Text Available Abstract.--The majority of taxonomic descriptions is currently in print format. The majority of digital descriptions are in formats such as DOC, HTML, or PDF and for human readers. These formats do not convey rich semantics in taxonomic descriptions for computer-aided process. Newer digital formats such as XML and RDF accommodate semantic annotations that allow computers to process the rich semantics on human's behalf, thus open up opportunities for a wide range of innovative usages of taxonomic descriptions, such as searching in more precise and flexible ways, integrating with gnomic and geographic information, generating taxonomic keys automatically, and text data mining and information visualization etc. This paper discusses the challenges in automated conversion of multiple collections of descriptions to XML format and reports an automated system, MARTT. MARTT is a machine-learning system that makes use of training examples to tag new descriptions into XML format. A number of utilities are implemented as solutions to the challenges. The utilities are used to reduce the effort for training example preparation, to facilitate the creation of a comprehensive schema, and to predict system performance on a new collection of descriptions. The system has been tested with several plant and alga taxonomic publications including Flora of China and Flora of North America.

    Sturm, Bob L.; Bardeli, Rolf; Langlois, Thibault

    2015-01-01

    The lack of a formalism for “the problem of music descrip- tion” results in, among other things: ambiguity in what problem a music description system must address, how it should be evaluated, what criteria define its success, and the paradox that a music description system can reproduce the “ground...... truth” of a music dataset without attending to the music it contains. To address these issues, we formal- ize the problem of music description such that all elements of an instance of it are made explicit. This can thus inform the building of a system, and how it should be evaluated in a meaningful way...

    2005-09-01

    Full Text Available Different library departments must work together, both formally and informally, in implementing encoded archival description and in repackaging descriptive information about archival collections to other formats, particularly machine-readable cataloging. The authors, one a technical services librarian and the other a special collections archivist, describe their experiences collaborating in these processes at The Ohio State University. Although other institutions may differ in their organizational structure, the authors hope to provide technical guidance, as well as a model of collaboration between archivists and technical services personnel. Careful dialogue and planning are essential to transcend the traditional divide between archival and library descriptive practices and systems.

  3. Descriptive and inferential statistical methods used in burns research.

    2010-05-01

    Burns research articles utilise a variety of descriptive and inferential methods to present and analyse data. The aim of this study was to determine the descriptive methods (e.g. mean, median, SD, range, etc.) and survey the use of inferential methods (statistical tests) used in articles in the journal Burns. This study defined its population as all original articles published in the journal Burns in 2007. Letters to the editor, brief reports, reviews, and case reports were excluded. Study characteristics, use of descriptive statistics and the number and types of statistical methods employed were evaluated. Of the 51 articles analysed, 11(22%) were randomised controlled trials, 18(35%) were cohort studies, 11(22%) were case control studies and 11(22%) were case series. The study design and objectives were defined in all articles. All articles made use of continuous and descriptive data. Inferential statistics were used in 49(96%) articles. Data dispersion was calculated by standard deviation in 30(59%). Standard error of the mean was quoted in 19(37%). The statistical software product was named in 33(65%). Of the 49 articles that used inferential statistics, the tests were named in 47(96%). The 6 most common tests used (Student's t-test (53%), analysis of variance/co-variance (33%), chi(2) test (27%), Wilcoxon & Mann-Whitney tests (22%), Fisher's exact test (12%)) accounted for the majority (72%) of statistical methods employed. A specified significance level was named in 43(88%) and the exact significance levels were reported in 28(57%). Descriptive analysis and basic statistical techniques account for most of the statistical tests reported. This information should prove useful in deciding which tests should be emphasised in educating burn care professionals. These results highlight the need for burn care professionals to have a sound understanding of basic statistics, which is crucial in interpreting and reporting data. Advice should be sought from professionals

    1997-09-01

    The intention of this report is to present a condensed technical description of Sizewell B in a language understandable to non-technical personnel. It is unavoidable that some parts will be less precise than the technically initiated would like to see, but hopefully the content still give a realistic picture of Sizewell B. The technical description is based on publicly available material, of which the Sizewell B safety report has been particularly useful. Nearly all figures and drawings found in this description are reproductions of corresponding material in the safety report. To keep the description from becoming too voluminous it has been necessary to condense some background material down to a small volume. Hopefully this has not introduced any errors or inaccuracies, possible oversimplification at certain points must be weighed against the wish to cover most of the topics in the agreed table of contents for these NKS reports.

  12. Mining skeletal phenotype descriptions from scientific literature.

    Directory of Open Access Journals (Sweden)

    Tudor Groza

    Full Text Available Phenotype descriptions are important for our understanding of genetics, as they enable the computation and analysis of a varied range of issues related to the genetic and developmental bases of correlated characters. The literature contains a wealth of such phenotype descriptions, usually reported as free-text entries, similar to typical clinical summaries. In this paper, we focus on creating and making available an annotated corpus of skeletal phenotype descriptions. In addition, we present and evaluate a hybrid Machine Learning approach for mining phenotype descriptions from free text. Our hybrid approach uses an ensemble of four classifiers and experiments with several aggregation techniques. The best scoring technique achieves an F-1 score of 71.52%, which is close to the state-of-the-art in other domains, where training data exists in abundance. Finally, we discuss the influence of the features chosen for the model on the overall performance of the method.

    Full Text Available It is no longer considered surprising that black holes have temperatures and entropies. What remains surprising, though, is the universality of these thermodynamic properties: their exceptionally simple and general form, and the fact that they can be derived from many very different descriptions of the underlying microscopic degrees of freedom. I review the proposal that this universality arises from an approximate conformal symmetry, which permits an effective “conformal dual” description that is largely independent of the microscopic details.

    The purpose of this methodology paper is to describe an approach to qualitative design known as qualitative descriptive that is well suited to junior health sciences researchers because it can be used with a variety of theoretical approaches, sampling techniques, and data collection strategies. It is often difficult for junior qualitative researchers to pull together the tools and resources they need to embark on a high-quality qualitative research study and to manage the volumes of data they collect during qualitative studies. This paper seeks to pull together much needed resources and provide an overview of methods. A step-by-step guide to planning a qualitative descriptive study and analyzing the data is provided, utilizing exemplars from the authors' research. This paper presents steps to conducting a qualitative descriptive study under the following headings: describing the qualitative descriptive approach, designing a qualitative descriptive study, steps to data analysis, and ensuring rigor of findings. The qualitative descriptive approach results in a summary in everyday, factual language that facilitates understanding of a selected phenomenon across disciplines of health science researchers. © The Author(s) 2016.

    This article describes case study research for nursing and healthcare practice. Case study research offers the researcher an approach by which a phenomenon can be investigated from multiple perspectives within a bounded context, allowing the researcher to provide a 'thick' description of the phenomenon. Although case study research is a flexible approach for the investigation of complex nursing and healthcare issues, it has methodological challenges, often associated with the multiple methods used in individual studies. These are explored through examples of case study research carried out in practice and education settings. An overview of what constitutes 'good' case study research is proposed.

    We derive self-consistent formalism for the description of multi-component partially ionized solar plasma, by means of the coupled equations for the charged and neutral components for an arbitrary number of chemical species, and the radiation field. All approximations and assumptions are carefully considered. Generalized Ohm's law is derived for the single-fluid and two-fluid formalism. Our approach is analytical with some order-of-magnitude support calculations. After general equations are developed, we particularize to some frequently considered cases as for the interaction of matter and radiation.

    The Math Description Engine Software Development Kit (MDE SDK) can be used by software developers to make computer-rendered graphs more accessible to blind and visually-impaired users. The MDE SDK generates alternative graph descriptions in two forms: textual descriptions and non-verbal sound renderings, or sonification. It also enables display of an animated trace of a graph sonification on a visual graph component, with color and line-thickness options for users having low vision or color-related impairments. A set of accessible graphical user interface widgets is provided for operation by end users and for control of accessible graph displays. Version 1.0 of the MDE SDK generates text descriptions for 2D graphs commonly seen in math and science curriculum (and practice). The mathematically rich text descriptions can also serve as a virtual math and science assistant for blind and sighted users, making graphs more accessible for everyone. The MDE SDK has a simple application programming interface (API) that makes it easy for programmers and Web-site developers to make graphs accessible with just a few lines of code. The source code is written in Java for cross-platform compatibility and to take advantage of Java s built-in support for building accessible software application interfaces. Compiled-library and NASA Open Source versions are available with API documentation and Programmer s Guide at http:/ / prim e.jsc.n asa. gov.

  10. The Theory of Nearly Incompressible Magnetohydrodynamic Turbulence: Homogeneous Description

    Science.gov (United States)

    Zank, G. P.; Adhikari, L.; Hunana, P.; Shiota, D.; Bruno, R.; Telloni, D.; Avinash, K.

    2017-09-01

    The theory of nearly incompressible magnetohydrodynamics (NI MHD) was developed to understand the apparent incompressibility of the solar wind and other plasma environments, particularly the relationship of density fluctuations to incompressible manifestations of turbulence in the solar wind and interstellar medium. Of interest was the identification of distinct leading-order incompressible descriptions for plasma beta β ≫ 1 and β ∼ 1 or ≪ 1 environments. In the first case, the “dimensionality” of the MHD description is 3D whereas for the latter two, there is a collapse of dimensionality in that the leading-order incompressible MHD description is 2D in a plane orthogonal to the large-scale or mean magnetic field. Despite the success of NI MHD in describing fluctuations in a low-frequency plasma environment such as the solar wind, a basic turbulence description has not been developed. Here, we rewrite the NI MHD system in terms of Elsässer variables. We discuss the distinction that emerges between the three cases. However, we focus on the β ∼ 1 or ≪ 1 regimes since these are appropriate to the solar wind and solar corona. In both cases, the leading-order turbulence model describes 2D turbulence and the higher-order description corresponds to slab turbulence, which forms a minority component. The Elsäasser β ∼ 1 or ≪ 1 formulation exhibits the nonlinear couplings between 2D and slab components very clearly, and shows that slab fluctuations respond in a passive scalar sense to the turbulently evolving majority 2D component fluctuations. The coupling of 2D and slab fluctuations through the β ∼ 1 or ≪ 1 NI MHD description leads to a very natural emergence of the “Goldreich-Sridhar” critical balance scaling parameter, although now with a different interpretation. Specifically, the critical balance parameter shows that the energy flux in wave number space is a consequence of the intensity of Alfvén wave sweeping versus passive scalar

    Rodrigo Antonio Brandão Neto

    Full Text Available CONTEXT: Erythema induratum of Bazin (EIB is considered to be a tuberculid reaction and consists of recurrent painful nodules. The differential diagnosis includes diseases like nodular vasculitis, perniosis, polyarteritis nodosa and erythema nodosum. CASE REPORT: We report the case of a woman with EIB who developed Addison's disease during treatment with anti-tuberculosis drugs with good response to glucocorticoid replacement. The diagnosis was obtained through the clinical picture, positive tuberculin test and positive BCG (bacillus Calmette-Guérin test on the histological sample. Anti-tuberculosis drugs and glucocorticoid replacement led to disappearance of the signs and symptoms. CONCLUSIONS: This is the first description of an association between EIB and Addison's disease. It should be borne in mind that tuberculosis is an important etiological factor for Addison's disease.

    Directory of Open Access Journals (Sweden)

    M. Cadoni

    2018-01-01

    Full Text Available We propose an effective anisotropic fluid description for a generic infrared-modified theory of gravity. In our framework, the additional component of the acceleration, commonly attributed to dark matter, is explained as a radial pressure generated by the reaction of the dark energy fluid to the presence of baryonic matter. Using quite general assumptions, and a microscopic description of the fluid in terms of a Bose–Einstein condensate of gravitons, we find the static, spherically symmetric solution for the metric in terms of the Misner–Sharp mass function and the fluid pressure. At galactic scales, we correctly reproduce the leading MOND-like log⁡(r and subleading (1/rlog⁡(r terms in the weak-field expansion of the potential. Our description also predicts a tiny (of order 10−6 for a typical spiral galaxy Machian modification of the Newtonian potential at galactic scales, which is controlled by the cosmological acceleration.

    The purpose of this system description document (SDD) is to establish requirements that drive the design of the surface industrial heating, ventilation, and air-conditioning (HVAC) system and its bases to allow the design effort to proceed to license application. This SDD will be revised at strategic points as the design matures. This SDD identifies the requirements and describes the system design, as it currently exists, with emphasis on attributes of the design provided to meet the requirements. This SDD is an engineering tool for design control; accordingly, the primary audience and users are design engineers. This SDD is part of an iterative design process. It leads the design process with regard to the flowdown of upper tier requirements onto the system. Knowledge of these requirements is essential to performing the design process. The SDD follows the design with regard to the description of the system. The description that provided in this SDD reflects the current results of the design process.

  14. A Domain Description Language for Data Processing

    2003-01-01

    We discuss an application of planning to data processing, a planning problem which poses unique challenges for domain description languages. We discuss these challenges and why the current PDDL standard does not meet them. We discuss DPADL (Data Processing Action Description Language), a language for describing planning domains that involve data processing. DPADL is a declarative, object-oriented language that supports constraints and embedded Java code, object creation and copying, explicit inputs and outputs for actions, and metadata descriptions of existing and desired data. DPADL is supported by the IMAGEbot system, which we are using to provide automation for an ecological forecasting application. We compare DPADL to PDDL and discuss changes that could be made to PDDL to make it more suitable for representing planning domains that involve data processing actions.

    We propose an effective anisotropic fluid description for a generic infrared-modified theory of gravity. In our framework, the additional component of the acceleration, commonly attributed to dark matter, is explained as a radial pressure generated by the reaction of the dark energy fluid to the presence of baryonic matter. Using quite general assumptions, and a microscopic description of the fluid in terms of a Bose-Einstein condensate of gravitons, we find the static, spherically symmetric solution for the metric in terms of the Misner-Sharp mass function and the fluid pressure. At galactic scales, we correctly reproduce the leading MOND-like log ⁡ (r) and subleading (1 / r) log ⁡ (r) terms in the weak-field expansion of the potential. Our description also predicts a tiny (of order 10-6 for a typical spiral galaxy) Machian modification of the Newtonian potential at galactic scales, which is controlled by the cosmological acceleration.

    Progress in science depends on the effective exchange of ideas among scientists. New ideas can be assessed and criticized in a meaningful manner only if they are formulated precisely. This applies to simulation studies as well as to experiments and theories. But after more than 50 years of neuronal network simulations, we still lack a clear and common understanding of the role of computational models in neuroscience as well as established practices for describing network models in publications. This hinders the critical evaluation of network models as well as their re-use. We analyze here 14 research papers proposing neuronal network models of different complexity and find widely varying approaches to model descriptions, with regard to both the means of description and the ordering and placement of material. We further observe great variation in the graphical representation of networks and the notation used in equations. Based on our observations, we propose a good model description practice, composed of guidelines for the organization of publications, a checklist for model descriptions, templates for tables presenting model structure, and guidelines for diagrams of networks. The main purpose of this good practice is to trigger a debate about the communication of neuronal network models in a manner comprehensible to humans, as opposed to machine-readable model description languages. We believe that the good model description practice proposed here, together with a number of other recent initiatives on data-, model-, and software-sharing, may lead to a deeper and more fruitful exchange of ideas among computational neuroscientists in years to come. We further hope that work on standardized ways of describing—and thinking about—complex neuronal networks will lead the scientific community to a clearer understanding of high-level concepts in network dynamics, and will thus lead to deeper insights into the function of the brain.

    2002-12-01

    Sediment colour data are delivered by geologists as Munsell codes (Rock Color Chart) and linguistic descriptions. Using new software suitable for very large data sets, the two types can be brought into conformance and mapped together digitally. The native codes are extracted. For linguistic descriptions chromatic terms are identified with Munsell codes, then mixed in a temporary transform of psychometrically linear CIE colour space. Adjustments are made for dark/light and pale/strong modifiers. The output Munsell codes are statistically validated and mapped using special GIS legends to render them in true colour. The output displays provide a new view of marine sediment facies, comparable to remotely sensed colour imagery.

    Rissanen, Marja-Liisa; Kylmä, Jari; Laukkanen, Eila

    2008-01-01

    The purpose of this study was to describe self-mutilation from the perspectives of self-mutilating adolescents. A qualitative descriptive design was adopted. Self-mutilating adolescents were asked to write descriptions of their self-mutilation. Data analysis revealed three major categories: descriptions of the factors contributing to self-mutilation, descriptions of the act of self-mutilation, and descriptions of the sequels of self-mutilation. This study adds to our understanding of self-mutilation and the experiences of self-mutilating adolescents. In nursing practice and education, self-mutilation should be discussed based on existing knowledge to make nurses more familiar with it. Nurses should understand this phenomenon as a challenge for developing effective nursing practices.

  2. Multiple Description Coding with Redundant Expansions and Application to Image Communications

    2007-01-01

    Full Text Available Multiple description coding offers an elegant and competitive solution for data transmission over lossy packet-based networks, with a graceful degradation in quality as losses increase. In the same time, coding techniques based on redundant transforms give a very promising alternative for the generation of multiple descriptions, mainly due to redundancy inherently given by a transform, which offers intrinsic resiliency in case of loss. In this paper, we show how partitioning of a generic redundant dictionary can be used to obtain an arbitrary number of multiple complementary, yet correlated, descriptions. The most significant terms in the signal representation are drawn from the partitions that better approximate the signal, and split to different descriptions, while the less important ones are alternatively distributed between the descriptions. As compared to state-of-the-art solutions, such a strategy allows for a better central distortion since atoms in different descriptions are not identical; in the same time, it does not penalize the side distortions significantly since atoms from the same partition are likely to be highly correlated. The proposed scheme is applied to the multiple description coding of digital images, and simulation results show increased performances compared to state-of-the-art schemes, both in terms of distortions and robustness to loss rate variations.

  4. Description of surface systems. Preliminary site description Simpevarp sub area - Version 1.2

    Lindborg, Tobias (ed.)

    2005-03-01

    Swedish Nuclear Fuel and Waste Management Co is currently conducting site characterisation in the Simpevarp area. The area is divided into two subareas, the Simpevarp and the Laxemar subarea. The two subareas are surrounded by a common regional model area, the Simpevarp area. This report describes both the regional area and the subareas. This report is an interim version (model version 1.2) of the description of the surface systems at the Simpevarp area, and should be seen as a background report to the site description of the Simpevarp area, version 1.2, SKB-R--05-08. The basis for this description is quality-assured field data available in the SKB SICADA and GIS databases, together with generic data from the literature. The Surface system, here defined as everything above the bedrock, comprises a number of separate disciplines (e.g. hydrology, geology, topography, oceanography and ecology). Each discipline has developed descriptions and models for a number of properties that together represent the site description. The current methodology for developing the surface system description and the integration to ecosystem models is documented in a methodology strategy report SKB-R--03-06. The procedures and guidelines given in that report were followed in this report. Compared with version 1.1 of the surface system description SKB-R--04-25, this report presents considerable additional features, especially in the ecosystem description (Chapter 4) and in the description of the surface hydrology (Section 3.4). A first attempt has also been made to connect the flow of matter (carbon) between the different ecosystems into an overall ecosystem model at a landscape level. A summarised version of this report is also presented in SKB-R--05-08 together with geological-, hydrogeological-, transport properties-, thermal properties-, rock mechanics- and hydrogeochemical descriptions.

    2017-09-01

    In Ontario, we identified that few hospitals have developed multi-disciplinary case conferences or forums for discussion of patients with palliative care issues. We describe the process of creating a province-wide standards document for palliative care multidisciplinary case conferences (pMCCs). A provincial survey and a multidisciplinary cancer conference symposium identified pMCCs as a priority. A literature search focusing on pMCCs and their implementation was completed as well as a current state assessment (survey and interviews) to understand challenges with existing pMCCs in Ontario. A working group was then assembled to draft a recommendation report that was finalized by an expert panel. A total of 22 articles were identified and 10 were used by the working group to create a framework for the pMCC guideline. The current state assessment identified substantial variability in pMCC structure and function. The expert panel made recommendations about meeting format (multidisciplinary discussion encouraged), frequency (at least every two weeks), type of cases to present, attendees (palliative care, nursing, primary care, social work, and community nursing), provider roles and responsibilities, and institutional requirements (pMCC coordinator, meeting room and videoconference capability). All patients (not just those with cancer) with palliative care needs were to be discussed at the pMCC, and pMCCs should serve as a crucial link between the hospital and community. We have described the process of creating the first pMCC guideline. A key component of this guideline is that pMCCs should serve as a link between the hospital and community.

    2014-12-01

    To conduct a review of reported cases of epidermal maturation arrest and to compare their clinical and histological descriptions with that of persistent granulation tissue with a focus on diagnostic methods and response to treatment. The authors performed a literature search within Pubmed, Embase, Google Scholar, and Web of Science for all reported cases of epidermal maturation arrest under the terms "epidermal maturation arrest," "epidermal arrest," "epidermal maturation," and "re-epithelialization maturation arrest." They reviewed the clinical and histological presentation of hypergranulation tissue as well as the evidence for the most widely used treatments. There is only one case series and one case report of epidermal maturation arrest, and the former gives the most detailed clinical and histological description including response to treatment. The clinical description, histological findings, and response to treatment of all cases are comparable to that of persistent granulation tissue and there is no histological or cytological data provided to support that epidermal maturation arrest exists as a distinct entity. Among the cases of epidermal maturation arrest reported in the literature, there is insufficient evidence that keratinocytes acquired a state of arrest in their migration. Rather, the described cases appear to have been complicated by persistent granulation tissue, a well-known aberration in wound healing.

  8. Description of surface systems. Preliminary site description. Forsmark area Version 1.2

    Energy Technology Data Exchange (ETDEWEB)

    Lindborg, Tobias (ed.)

    2005-06-01

    Swedish Nuclear Fuel and Waste Management Co (SKB) started site investigations for a deep repository for spent nuclear fuel in 2002 at two different sites in Sweden, Forsmark and Oskarshamn. The investigations should provide necessary information for a license application aimed at starting underground exploration. For this reason, ecosystem data need to be interpreted and assessed into site descriptive models, which in turn are used for safety assessment studies and for environmental impact assessment. Descriptions of the surface system are also needed for further planning of the site investigations. This report describes the surface ecosystems of the Forsmark site (e.g. hydrology, Quaternary deposits, chemistry, vegetation, animals and the human land use). The ecosystem description is an integration of the site and its regional setting, covering the current state of the biosphere as well as the ongoing natural processes affecting the longterm development. Improving the descriptions is important during both the initial and the complete site investigation phase. Before starting of the initial phase in Forsmark, version 0 of the site descriptive model was developed. The results of the initial site investigation phase is compiled into a preliminary site description of Forsmark (version 1.2) in June 2005. This report provides the major input and background to the biosphere description, in the 1.2 version of the Forsmark site description. The basis for this interim version is quality-assured field data from the Forsmark sub area and regional area, available in the SKB SICADA, and GIS data bases as of July 31th 2004 as well as version 1.1 of the Site Descriptive Model. To achieve an ecosystem site description there is a need to develop discipline-specific models by interpreting and analysing primary data. The different discipline-specific models are then integrated into a system describing interactions and flows and stocks of matter between and within functional units in

  11. Instructions for Radiological Case Reports.

    Science.gov (United States)

    Bannas, Peter

    2017-04-01

    Purpose  This paper explains the purpose and structure of a radiological case report and provides guidance for radiologists with respect to the writing of a well-structured patient case report. Materials and Methods  The current literature and the author's experience as a writer were used to create a manual that describes steps for preparing a radiological case report containing all of the important ingredients for effective communication. Results  Case reports are the first line of evidence in documenting clinical observations in the literature. A case report should be written succinctly and consists of four structured main sections: introduction, description of the case, discussion and conclusion. Its structure follows the structure of an original research article, whereby the description of the case of the case report corresponds to the materials and methods section of the research article. The introduction provides the subject and merit of the case report with respect to the published literature. The case description presents the case in detail and chronological order to allow for plausibility. The discussion compares the case with the published literature and summarizes the essential features. A case report, like an original article, must provide a justified conclusion.

    Objective: Perceived descriptive drinking norms often differ from actual norms and are positively related to personal consumption. However, it is not clear how normative perceptions vary with specificity of the reference group. Are drinking norms more accurate and more closely related to drinking behavior as reference group specificity increases? Do these relationships vary as a function of participant demographics? The present study examined the relationship between perceived descriptive norms and drinking behavior by ethnicity (Asian or White), sex, and fraternity/sorority status. Method: Participants were 2,699 (58% female) White (75%) or Asian (25%) undergraduates from two universities who reported their own alcohol use and perceived descriptive norms for eight reference groups: "typical student"; same sex, ethnicity, or fraternity/sorority status; and all combinations of these three factors. Results: Participants generally reported the highest perceived norms for the most distal reference group (typical student), with perceptions becoming more accurate as individuals' similarity to the reference group increased. Despite increased accuracy, participants perceived that all reference groups drank more than was actually the case. Across specific subgroups (fraternity/sorority members and men) different patterns emerged. Fraternity/sorority members reliably reported higher estimates of drinking for reference groups that included fraternity/ sorority status, and, to a lesser extent, men reported higher estimates for reference groups that included men. Conclusions: The results suggest that interventions targeting normative misperceptions may need to provide feedback based on participant demography or group membership. Although reference group-specific feedback may be important for some subgroups, typical student feedback provides the largest normative discrepancy for the majority of students. PMID:21906510

    Full Text Available A descriptive study of patients diagnosed with carpal tunnel syndrome was carried out at “Manuel Piti Fajardo” Teaching Polyclinic of Las Tunas, from January to December, 2008. The study was aimed at describing them clinically and epidemiologically. The sample was made up of 50 patients older than 14 years old, who were characterized according to: age, sex, individual pathological antecedents factors associated to the triggering of theirsymptomatology, as well as clinical signs and symptoms. The results were processed using the descriptive statistics by means of percentage analysis. The prevailing results were: female patients, for a 76%; 41 to 50 age group, for a 40%; antecedents of osteoarthrosis, for a 34%. The factor which triggered the onset of the symptoms was the occupation of office worker, for a 46%, while 4 patients (8% came to the consultation office with more than 6 months of symptom evolution.

The mean absolute error relative to experiments is 0.21 eV and 0.38 eV per oxygen atom for rAPBE and RPA, respectively, and thus the rAPBE method greatly improves the description of metal-oxygen bonds across a wide range of oxides. The failure of the RPA can be partly attributed...... to the lack of error cancellation between the correlation energy of the oxide on the one hand and the bulk metal and oxygen molecule on the other hand, which are all separately predicted much too negative by the RPA.

  7. Towards a Mathematical Description of Biodiversity Evolution

    Directory of Open Access Journals (Sweden)

    Jorge E. Horvath

    2014-09-01

    Full Text Available We outline in this work a mathematical description of biodiversity evolution based on a second-order differential equation (also known as the “inertial/Galilean view”. After discussing the motivations and explicit forms of the simplest “forces”, we are lead to an equation analogue to a harmonic oscillator. The known solutions for the homogeneous problem are then tentatively related to the biodiversity curves of Sepkoski and Alroy et al., suggesting mostly an inertial behavior of the time evolution of the number of genera and a quadratic behavior in some long-term evolution after extinction events. We present the Green function for the dynamical system and apply it to the description of the recovery curve after the Permo-Triassic extinction, as recently analyzed by Burgess, Bowring and Shen. Even though the agreement is not satisfactory, we point out direct connections between observed drop times after massive extinctions and mathematical constants and discuss why the failure ensues, suggesting a more complex form of the second-order mathematical description.

  8. Macroscopic Description for Networks of Spiking Neurons

    Science.gov (United States)

    Montbrió, Ernest; Pazó, Diego; Roxin, Alex

    2015-04-01

    A major goal of neuroscience, statistical physics, and nonlinear dynamics is to understand how brain function arises from the collective dynamics of networks of spiking neurons. This challenge has been chiefly addressed through large-scale numerical simulations. Alternatively, researchers have formulated mean-field theories to gain insight into macroscopic states of large neuronal networks in terms of the collective firing activity of the neurons, or the firing rate. However, these theories have not succeeded in establishing an exact correspondence between the firing rate of the network and the underlying microscopic state of the spiking neurons. This has largely constrained the range of applicability of such macroscopic descriptions, particularly when trying to describe neuronal synchronization. Here, we provide the derivation of a set of exact macroscopic equations for a network of spiking neurons. Our results reveal that the spike generation mechanism of individual neurons introduces an effective coupling between two biophysically relevant macroscopic quantities, the firing rate and the mean membrane potential, which together govern the evolution of the neuronal network. The resulting equations exactly describe all possible macroscopic dynamical states of the network, including states of synchronous spiking activity. Finally, we show that the firing-rate description is related, via a conformal map, to a low-dimensional description in terms of the Kuramoto order parameter, called Ott-Antonsen theory. We anticipate that our results will be an important tool in investigating how large networks of spiking neurons self-organize in time to process and encode information in the brain.

    Full Text Available The case report or case reports are a frequent type of narrative article in the biomedical literature. Case reports are useful to describe unusual clinical cases, identify adverse effects or benefits of therapies. They are also useful for the description of presentation of rare diseases for educational or scientific purposes. Several groups have worked on reporting guidelines for other designs such as the case of clinical trials (CONSORT Statement or observational studies (STROBE Statement and this journal has been adopted as the guide for authors. Recently, there were presented the Guidelines for writing CAseREports (CARE Statement. The aim of this article is to make them known and comment.

  10. Horizons of description: Black holes and complementarity

    Science.gov (United States)

    Bokulich, Peter Joshua Martin

    Niels Bohr famously argued that a consistent understanding of quantum mechanics requires a new epistemic framework, which he named complementarity . This position asserts that even in the context of quantum theory, classical concepts must be used to understand and communicate measurement results. The apparent conflict between certain classical descriptions is avoided by recognizing that their application now crucially depends on the measurement context. Recently it has been argued that a new form of complementarity can provide a solution to the so-called information loss paradox. Stephen Hawking argues that the evolution of black holes cannot be described by standard unitary quantum evolution, because such evolution always preserves information, while the evaporation of a black hole will imply that any information that fell into it is irrevocably lost---hence a "paradox." Some researchers in quantum gravity have argued that this paradox can be resolved if one interprets certain seemingly incompatible descriptions of events around black holes as instead being complementary. In this dissertation I assess the extent to which this black hole complementarity can be undergirded by Bohr's account of the limitations of classical concepts. I begin by offering an interpretation of Bohr's complementarity and the role that it plays in his philosophy of quantum theory. After clarifying the nature of classical concepts, I offer an account of the limitations these concepts face, and argue that Bohr's appeal to disturbance is best understood as referring to these conceptual limits. Following preparatory chapters on issues in quantum field theory and black hole mechanics, I offer an analysis of the information loss paradox and various responses to it. I consider the three most prominent accounts of black hole complementarity and argue that they fail to offer sufficient justification for the proposed incompatibility between descriptions. The lesson that emerges from this

  11. Selecting the appropriate study design for your research: Descriptive study designs

    Directory of Open Access Journals (Sweden)

    Aamir Omair

    2015-01-01

    Full Text Available This article describes the importance of selecting the appropriate epidemiological study design for a given study question. It provides an explanation to the different terms used in describing study designs with regards to observational versus interventional and descriptive versus analytical types of study designs. This article focuses on the description of the different types of descriptive study designs, that is, case report, case series, correlational, and cross-sectional study designs. The requirements for selecting these study designs are discussed along with the advantages and disadvantages of each study design. The descriptive studies are similar in the context that they are based on a single sample with no comparative group within the study design. Their basic purpose is to describe the characteristics of the sample with regards to the characteristics that are present and so are useful in generating a hypothesis. The absence of a comparative group is the main limitation of the descriptive studies, and this is the reason they cannot be used to determine an association by testing a hypothesis showing a relationship between a risk factor and disease. The analytical study designs will be discussed in the next article in this series.

  12. Lockhart Clarke's contribution to the description of amyotrophic lateral sclerosis.

    Science.gov (United States)

    Turner, Martin R; Swash, Michael; Ebers, George C

    2010-11-01

    The definition of the clinicopathological entity of amyotrophic lateral sclerosis evolved over half a century. Although the definitive term amyotrophic lateral sclerosis that acknowledged both upper and lower motor neuron involvement was attributed to Jean-Martin Charcot in 1874, his initial case was published nearly a decade earlier; and it is accepted that, from at least the 1830s, several others (including Charles Bell, François-Amilcar Aran and Jean Cruveilhier) had already recognized a progressive lower motor neuron-only syndrome within a broader, clinically-defined group of disorders, termed progressive muscular atrophy. Although William Gowers first grouped the three phenotypes of amyotrophic lateral sclerosis, progressive muscular atrophy and progressive bulbar palsy together as part of the same syndrome, the term motor neuron disease, as an over-arching label, was not suggested until nearly a century later by W. Russell Brain. Augustus Jacob Lockhart Clarke (1817-80) is best known for his descriptions of spinal cord anatomy. However, in two detailed case reports from the 1860s, he carried out rigorous post-mortem neuropathological studies of what appear to be classical cases of amyotrophic lateral sclerosis. Furthermore, he recognized the additional involvement of the corticospinal tracts that distinguished this from progressive muscular atrophy. Several aspects of the exquisite clinical histories documented as part of both studies, one by Charles Bland Radcliffe, resonate with contemporary debates concerning the evolution of disease in amyotrophic lateral sclerosis. These 'past masters' still have much to teach us.

  13. Generalized description of intermittency in turbulence via stochastic methods

    CERN Document Server

    Friedrich, J

    2016-01-01

    We present a generalized picture of intermittency in turbulence that is based on the theory of stochastic processes. To this end, we rely on the experimentally and numerically verified finding by R.~Friedrich and J.~Peinke [Phys. Rev. Lett. 78, 863 (1997)] that allows for an interpretation of the turbulent energy cascade as a Markov process of the velocity increments in scale. It is explicitly shown that all known phenomenological models of turbulence can be reproduced by the Kramers-Moyal expansion of the velocity increment probability density function that is associated to a Markov process. We compare the different sets of Kramers-Moyal coefficients of each phenomenology and deduce that an accurate description of intermittency should take into account an infinite number of coefficients. This is demonstrated in more detail for the case of Burgers turbulence that exhibits the strongest intermittency effects. Moreover, the influence of nonlocality on the Kramers-Moyal coefficients is investigated by direct num...

    Olivares, F; Pennini, F; Curilef, S

    2010-04-01

    In the present study we analyze some consequences that come from revised measures as the Wehrl entropy and the Fisher information for the problem of a particle in a magnetic field starting from a complete description of the Husimi function. We discuss in the most complete form (three dimensions) some results related to measures in contrast with the incomplete form (two dimensions) shown in previous contributions. Some limiting cases as high and low temperatures are discussed. From the present reasoning, it is suggested that the formulation in two dimensions is sufficient unto itself to explain the problem whenever the length of the cylindrical geometry of the system is large enough. Otherwise, it is not possible to work in all finite temperatures, a natural lower temperature bound emerges from the analysis when three dimensions are considered.

  16. The descriptive and epidemiological characteristics of cervical cancer

    Directory of Open Access Journals (Sweden)

    Vukićević D.

    2015-01-01

    Full Text Available Cervical cancer has long been a serious public health issue, both locally and worldwide. Efforts to control this disease should encompass prevention, as well as early detection and treatment, but also meticulous record-keeping and follow-up monitoring of affected women. In order to efficiently combat the disease, all of the above conditions must be met simultaneously. The goal of this article is to provide a layout of the fundamental descriptive and epidemiological characteristics of both cervical cancer patients and deaths resulting from the disease in Serbia, Europe and worldwide. We will pay special attention to a detailed epidemiological report on Central Serbia from 1999 to 2011. The article utilizes the approach of descriptive epidemiology to compound the knowledge about the disease, its incidence, and outcomes. The presented data was gathered from Globocan, a cancer surveillance database developed by the WHO, as well as the Cancer Registry of Central Serbia (for the aforementioned time period. There were 527624 new cases reported globally in 2012, corresponding to a standardized incidence ratio of 14,0 per 100000 women. Mortality-wise, there were 265653 deaths recorded in 2012, yielding a standardized mortality ratio of 6.8 per 100000 women. In other words, on average, every two minutes a woman dies of cervical cancer, totalling 720 cervical cancer mortalities per day. In Europe, there have been 58348 new cases in 2012 (11.44 per 100000 women, with 24378 deaths (3,75 per 100000 women. In Serbia, 1501 new cases were recorded in 2012 (23,8 per 100000 women, with 609 deaths (7,7 per 100000 women. These data make Serbia rank 62nd (out of 182 countries in terms of incidence, and 84th in terms of mortality of cervical cancer, putting Serbia in the top half of the world on both criteria. According to the data supplied by the Cancer Registry of Central Serbia, the average standardized incidence ratio of 23.9/100000 women and the SMR of 7

    Full Text Available A quantum-mechanical description of the phase shifters, retarders, mirrors and beam splitters is given in the paper. The description is then applied on two types of states. On a coherent state, a classical-like state, and on a number state, hence the strict quantum state. The quantum description of a beam splitter can be found in the literature. However the description does not treat with the polarization concept. The paper is aimed to introduce quantum description of an arbitrary oriented retarder and give a description of a beam splitter which treats with the polarization.

    Fluid mechanics is examined from a Hamiltonian perspective. The Hamiltonian point of view provides a unifying framework; by understanding the Hamiltonian perspective, one knows in advance (within bounds) what answers to expect and what kinds of procedures can be performed. The material is organized into five lectures, on the following topics: rudiments of few-degree-of-freedom Hamiltonian systems illustrated by passive advection in two-dimensional fluids; functional differentiation, two action principles of mechanics, and the action principle and canonical Hamiltonian description of the ideal fluid; noncanonical Hamiltonian dynamics with examples; tutorial on Lie groups and algebras, reduction-realization, and Clebsch variables; and stability and Hamiltonian systems.

  20. Descriptive mining for the QSAR problem

    Directory of Open Access Journals (Sweden)

    Lucian GEORGESCU

    2005-12-01

    Full Text Available There are several approaches in trying to solve the Quantitative Structure-Activity (QSAR problem. These approaches are based either on statistical methods or on predictive data mining using neural networks. Among the statistical methods, one should consider regression analysis, pattern recognition (such as cluster analysis, factor analysis and principal components analysis or partial least squares. These approaches have a low explanatory capability or non at all. This paper attempts to establish a new approach in solving QSSAR problems using descriptive data mining. This way, the relationship between the chemical properties and the activity of a substance would be comprehensibly modeled.

    Aranson, I. S.; Tsimring, L. S.

    2000-12-05

    A continuum theory of partially fluidized granular flows is proposed. The theory is based on a combination of the mass and momentum conservation equations with the order parameter equation which describes the transition between flowing and static components of the granular system. We apply this model to the dynamics of avalanches in chutes. The theory provides a quantitative description of recent observations of granular flows on rough inclined planes (Daerr and Douady 1999): layer bistability, and the transition from triangular avalanches propagating downhill at small inclination angles to balloon-shaped avalanches also propagating uphill for larger angles.

  4. Syndromic surveillance in Vanuatu since Cyclone Pam: a descriptive study

    Directory of Open Access Journals (Sweden)

    George Worwor

    2016-12-01

    Full Text Available In 2012, Vanuatu designed and implemented a syndromic surveillance system based on the guidelines developed by the Pacific Community and the World Health Organization to provide early warning of outbreaks and other important public health events. Four core syndromes were endorsed for surveillance: acute fever and rash, prolonged fever, influenza-like illness and acute watery diarrhoea. In March 2015, Vanuatu was struck by Cyclone Pam, after which several important changes and improvements to the country's syndromic surveillance were made. To date, there has been no formal evaluation of whether regular reports are occurring or that core syndromes are being documented. We therefore carried out a descriptive study in the 11 sentinel sites in Vanuatu conducting syndromic surveillance between July and December 2015. There was a total of 53 822 consultations which were higher in the first 13 weeks (n = 29 622 compared with the last 13 weeks (n = 24 200. During the six months, there were no cases of acute fever and rash or prolonged fever. There were cases with influenza-like illness from week 27 to 35, but no case was reported after week 35. Acute watery diarrhoea occurred in one or two cases per week during the whole study period. For these two core syndromes, there were generally more females than males, and about one third were children aged under 5 years. In conclusion, Vanuatu implemented changes to its new syndromic surveillance system from July to December 2015, although laboratory components had not yet been incorporated. The laboratory components are working in 2016 and will be the subject of a further report.

  5. Preliminary description of the transportation operations systems

    1988-03-01

    This document presents a preliminary description of the transportation operations systems designed to ship spent fuel and high-level waste (HLW) from waste generator sites to authorized waste receiving facilities. It is an initial effort to define the operations system and identifies the activities and system components necessary to provide complete transportation capability. It is intended that this be a project level working document to facilitate dialog for further identification of system elements and functional requirements. This process will lead to issuance of a System Requirements and Description (SRD) document for the transportation operations systems and will identify detailed system functional requirements, performance criteria, and functional interfaces. The transportation system is quite complex and is influenced by a large number of external factors and interfaces. Some of these interfaces (such as the repository) are just now being developed. Others (such as utility-handling capabilities) are currently in existence and must be accommodated or modified. Additionally, the allocation of requirements is likewise both developing (with the repository) and somewhat fixed. 16 refs., 15 figs., 12 tabs.

    Buck, R M; Lent, E M

    2009-09-21

    This COG Software Architecture Design Description Document describes the organization and functionality of the COG Multiparticle Monte Carlo Transport Code for radiation shielding and criticality calculations, at a level of detail suitable for guiding a new code developer in the maintenance and enhancement of COG. The intended audience also includes managers and scientists and engineers who wish to have a general knowledge of how the code works. This Document is not intended for end-users. This document covers the software implemented in the standard COG Version 10, as released through RSICC and IAEA. Software resources provided by other institutions will not be covered. This document presents the routines grouped by modules and in the order of the three processing phases. Some routines are used in multiple phases. The routine description is presented once - the first time the routine is referenced. Since this is presented at the level of detail for guiding a new code developer, only the routines invoked by another routine that are significant for the processing phase that is being detailed are presented. An index to all routines detailed is included. Tables for the primary data structures are also presented.

  7. Mathematical description of bacterial traveling pulses.

    Directory of Open Access Journals (Sweden)

    Jonathan Saragosti

    Full Text Available The Keller-Segel system has been widely proposed as a model for bacterial waves driven by chemotactic processes. Current experiments on Escherichia coli have shown the precise structure of traveling pulses. We present here an alternative mathematical description of traveling pulses at the macroscopic scale. This modeling task is complemented with numerical simulations in accordance with the experimental observations. Our model is derived from an accurate kinetic description of the mesoscopic run-and-tumble process performed by bacteria. This can account for recent experimental observations with E. coli. Qualitative agreements include the asymmetry of the pulse and transition in the collective behaviour (clustered motion versus dispersion. In addition, we can capture quantitatively the traveling speed of the pulse as well as its characteristic length. This work opens several experimental and theoretical perspectives since coefficients at the macroscopic level are derived from considerations at the cellular scale. For instance, the particular response of a single cell to chemical cues turns out to have a strong effect on collective motion. Furthermore, the bottom-up scaling allows us to perform preliminary mathematical analysis and write efficient numerical schemes. This model is intended as a predictive tool for the investigation of bacterial collective motion.

    During 2002, the Swedish Nuclear Fuel and Waste Management Company (SKB) is starting investigations at two potential sites for a deep repository in the Precambrian basement of the Fennoscandian Shield. The present report concerns one of those sites, Forsmark, which lies in the municipality of Oesthammar, on the east coast of Sweden, about 150 kilometres north of Stockholm. The site description should present all collected data and interpreted parameters of importance for the overall scientific understanding of the site, for the technical design and environmental impact assessment of the deep repository, and for the assessment of long-term safety. The site description will have two main components: a written synthesis of the site, summarising the current state of knowledge, as documented in the databases containing the primary data from the site investigations, and one or several site descriptive models, in which the collected information is interpreted and presented in a form which can be used in numerical models for rock engineering, environmental impact and long-term safety assessments. The site descriptive models are devised and stepwise updated as the site investigations proceed. The point of departure for this process is the regional site descriptive model, version 0, which is the subject of the present report. Version 0 is developed out of the information available at the start of the site investigation. This information, with the exception of data from tunnels and drill holes at the sites of the Forsmark nuclear reactors and the underground low-middle active radioactive waste storage facility, SFR, is mainly 2D in nature (surface data), and is general and regional, rather than site-specific, in content. For this reason, the Forsmark site descriptive model, version 0, as detailed in the present report, has been developed at a regional scale. It covers a rectangular area, 15 km in a southwest-northeast and 11 km in a northwest-southeast direction, around the

    Optical systems can benefit strongly from freeform surfaces; however, the choice of the right representation is not trivial, and many aspects must be considered. Many possibilities to formulate the surface equations in detail are available, but the experience with these newer representations is rather limited. Therefore, in this work, the focus is to investigate the performance of several classical descriptions as well as one extended freeform surface description in their performance in concrete design optimization tasks. There are different influencing factors characterizing the surface representations, the basic shape, the boundary function, the symmetry, a projection factor, as well as the deformation term describing higher order contributions. We discuss some possibilities and the consequences of describing and using these options with success. These surface representations were chosen to evaluate their impact on all these aspects in the design process. As criteria to distinguish the various options, the convergence over the polynomial orders, as well as the quality of the final solutions, is considered. As a result, recommendations for the right choice of freeform surface representations for practical issues in the optimization of optical systems can be given under restrictions of the benchmark assumptions.

  10. Initial rheological description of high performance concretes

    2006-12-01

    Full Text Available Concrete is defined as a composite material and, in rheological terms, it can be understood as a concentrated suspension of solid particles (aggregates in a viscous liquid (cement paste. On a macroscopic scale, concrete flows as a liquid. It is known that the rheological behavior of the concrete is close to that of a Bingham fluid and two rheological parameters regarding its description are needed: yield stress and plastic viscosity. The aim of this paper is to present the initial rheological description of high performance concretes using the modified slump test. According to the results, an increase of yield stress was observed over time, while a slight variation in plastic viscosity was noticed. The incorporation of silica fume showed changes in the rheological properties of fresh concrete. The behavior of these materials also varied with the mixing procedure employed in their production. The addition of superplasticizer meant that there was a large reduction in the mixture's yield stress, while plastic viscosity remained practically constant.

    A standard for the self-description of fusion plasma diagnostics will be required in the near future. The motivation is to maintain and organize the information on all the components of a laboratory experiment, from the hardware to the access security, to save time and money. Since there is no existing standard to organize this kind of information, every EU Association stores and organizes each experiment in different ways. This can lead to severe problems when the particular organization schema is poorly documented. Standardization is the key to solve these problems. From the commercial information on the diagnostic (component supplier; component price) to the hardware description (component specifications; drawings) to the operation of the equipment (finite state machines) through change control (who changed what and when) and internationalization (information at least in English and a local language). This problem will be met on the ITER project, for which a solution is essential. A strong candidate solution is the Extensible Markup Language (XML). In this paper, a review of the current status of XML related technologies will be presented.

    Athena is the ATLAS off-line software framework, based upon the GAUDI architecture from LHCb. As part of ATLAS' continuing efforts to enhance and customise the architecture to meet our needs, we have developed a data object description tool suite and service for Athena. The aim is to provide a set of tools to describe, manage, integrate and use the Event Data Model at a design level according to the concepts of the Athena framework (use of patterns, relationships, ...). Moreover, to ensure stability and reusability this must be fully independent from the implementation details. After an extensive investigation into the many options, we have developed a language grammar based upon a description language (IDL, ODL) to provide support for object integration in Athena. We have then developed a compiler front end based upon this language grammar, JavaCC, and a Java Reflection API-like interface. We have then used these tools to develop several compiler back ends which meet specific needs in ATLAS such as automatic...

  14. Quantum gravity from descriptive set theory

    Energy Technology Data Exchange (ETDEWEB)

    El Naschie, M.S

    2004-03-01

    We start from Hilbert's criticism of the axioms of classical geometry and the possibility of abandoning the Archimedean axiom. Subsequently we proceed to the physical possibility of a fundamental limitation on the smallest length connected to certain singular points in spacetime and below which measurements become meaningless, Finally we arrive at the conclusion that maximising the Hawking-Bekenstein informational content of spacetime makes the existence of a transfinite geometry for physical 'spacetime' not only plausible but probably inevitable. The main part of the paper is then concerned with a proposal for a mathematical description of a transfinite, non-Archimedean geometry using descriptive set theory. Nevertheless, and despite all abstract mathematics, we remain quite close to similar lines of investigation initiated by physicists like A. Wheeler, D. Finkelstein and G. 'tHooft. In particular we introduce a logarithmic gauge transformation linking classical gravity with the electro weak via a version of informational entropy. That way we may claim to have accomplished an important step towards a general theory of quantum gravity using {epsilon}{sup ({infinity}}{sup )} and complexity theory and finding that {alpha}{sub G}=(2){sup {alpha}}{sup -bar{sub ew-1}} congruent with (1.7)(10){sup 38} where {alpha}{sub G} is the dimensionless Newton gravity constant, and {alpha}{sub ew}{approx_equal}128 is the fine structure constant at the electro weak scale.

    2008-01-01

    We report a case of massive associative visual agnosia. In the light of current theories of identification and semantic knowledge organization, a deficit involving both levels of structural description system and visual semantics must be assumed to explain the case. We suggest, in line with a previous case study [1], an alternative account in the framework of (non abstractive) episodic models of memory [4].

    An outbreak of human parvovirus-associated erythema infectiosum in the Grampian region has enabled us to study the association between this small DNA virus and arthritis. This report deals with 42 patients with joint pains, in whom serological evidence of recent human parvovirus (HPV) infection was obtained. The clinical description of the disorder is based on 17 of the patients who were seen in the clinic and a further 13 patients for whom information was obtained by questionnaire. Detailed clinical features were not available for the remaining 12 patients. A rash was present in all 3 affected children but only 13 of the 27 adults. Viral prodromata were present in only 13 adults. 7 adults had neither rash nor viral prodromata. The arthritis was more common in adults than children and affected principally the female sex. In adults the arthritis was symmetrical, affecting the small joints of the hands, wrists, and knees most commonly. In all cases it was self-limiting, usually resolving within 4 weeks, although 1 adult had more persistent disease lasting almost 6 months. The 3 children reported in detail had less symmetrical and more persistent disease, which in 1 case has lasted over 7 months.
