    Quantum annealing is a proposed combinatorial optimization technique meant to exploit quantum mechanical effects such as tunneling and entanglement. Real-world quantum annealing-based solvers require a combination of annealing and classical pre- and post-processing; at this early stage, little is known about how to partition and optimize the processing. This article presents an experimental case study of quantum annealing and some of the factors involved in real-world solvers, using a 504-qubit D-Wave Two machine and the graph isomorphism problem. To illustrate the role of classical pre-processing, a compact Hamiltonian is presented that enables a reduced Ising model for each problem instance. On random N-vertex graphs, the median number of variables is reduced from N(2) to fewer than N log2 N and solvable graph sizes increase from N = 5 to N = 13. Additionally, error correction via classical post-processing majority voting is evaluated. While the solution times are not competitive with classical approaches to graph isomorphism, the enhanced solver ultimately classified correctly every problem that was mapped to the processor and demonstrated clear advantages over the baseline approach. The results shed some light on the nature of real-world quantum annealing and the associated hybrid classical-quantum solvers.

    Full Text Available Three case studies involving Leptospira interrogans serovar pomona outbreaks within mixed farming systems in South Africa are described. On 2 farms, pigs constituted the main enterprise with cattle and sheep of secondary importance. On each of these 2 farms, abortion due to L. pomona in sows was confirmed by culture, and antibody titres to pomona were detected in cattle, sheep, horses and dogs. On the 3rd farm, a piggery was ofsecondary importance to cattle farming. Abortion and death in cows occurred on this farmand serology showed titres to various serovars, including pomona. L. pomona was also isolated from bovine urine, an aborted bovine foetus and kidneys from slaughtered pigs. This particular case study was regarded as clinically atypical in that adult Jersey cattle died of acute leptospirosis in a semiarid region of South Africa. In all 3 case studies, the poor management of pig effluent and of the drinking water and its sources played a pivotal role in the transmission of the disease. Inadequate vaccination of animals against Leptospira and poor record-keeping within the secondary farming enterprises were also contributing factors to the spread of leptospirosis.

    2001-05-01

    A multiple case study design was used to explore dimensions of organizational values in general practice with respect to developing public involvement. The study was undertaken in an urban district in England with data collected through in-depth individual and focus group interviews with service providers and service users. Four general practice organizations were randomly selected for study after sorting all in the district according to their record of developing involvement activities. The case studies provide evidence of how organizational values can differ markedly in general practice in relation to ideas of public involvement, with consequences for the quantity and quality of activities for involving local people and service users. The differences manifest themselves in the beliefs and attitudes of service providers about the purpose of the organization and the types of relationships that are appropriate with service users and local people. Service users appear to be very perceptive to the underlying ethos and purpose to their practice organization and this affects their responsiveness to initiatives for their involvement. The dimensions of the different values found in the study appear to be essentially the same as a number of established empirical findings of variations in values in general practice: an orientation to a narrow medical role and to general practice as a business are associated with a low valuation of involvement; an orientation to teamwork and to a broader social role appear more congruent with the development of involvement. Power is a critical issue in this setting with evidence in the study of the dominance of the medical practitioners in establishing organizational values and the nature of public involvement activities.

    Full Text Available Abstract Background Many large studies have complex advisory committee structures, yet there is no empirical evidence regarding their optimal composition, scope and contribution. The aim of this study was to inform the committee and advice infrastructure for future research studies. Methods In the context of a five-year study funded by the UK National Institute for Health Research, three advisory committees were formed. In addition, advice was obtained from individual experts. All recommendations received in the start-up phase (first seven months of the study were recorded, along with the decision about implementation of the recommendation. A particular focus was on the impact of public involvement. Results A total of 172 recommendations were made, including 70 from 20 individual experts. The recommendations were grouped into five emergent themes: Scientific, Pragmatic, Resources, Committee and Collaboration. Most recommendations related to strengthening existing components or adding new components to the study protocol. Very few recommendations either proposed removing study components or contradicted other recommendations. Three 'implementation criteria' were identified: scientific value, pragmatic feasibility, and paradigmatic consistency. 103 (60% of recommendations were implemented and 25 (15% were not implemented. The benefits identified by the research team were improved quality and confidence, and the costs were increased cognitive demands, protocol revision time, and slower progress. Conclusions The findings are discussed in the context of the wider literature on public involvement in research. Six recommendations are identified. First, have a clear rationale for each advisory committee expressed as terms of reference, and consider the best balance between committees and individual consultation with experts. Second, an early concern of committees is inter-committee communication, so consider cross-representation and copying minutes

    2010-01-01

    Full Text Available Founded on practical rationality, this qualitative case study aimed to explore the teaching practice at university, focusing on teacher's reflections and competencies. To this end, teaching practices were described, analyzed, and interpreted. These interactions with students on a course in the pharmacy program, brought about situations involving dilemmas and learning opportunities for problem-solving and decision-making skills. Throughout the study, students were encouraged to use knowledge-in-action, reflection-in-action, and reflection-on-action, and these processes were also experienced by the teacher. Analysis of the records from classroom observation and the interviews with students and the teacher showed the fundamental role of such reflective processes, which led to attainment of the intended objectives. In this sense, the teacher's reflective practice was essential for supporting the application of each curricular component of the course.

  9. EMPLOYEE INVOLVEMENT IN A CHANGE PROCESS - A CASE STUDY FOR ROMANIAN ORGANIZATIONS

    2015-07-01

    Full Text Available Innovation, competitive advantage, change are some concepts that should be on every organization's agenda, due to the fact the global market leads to global competition so in order to increase the market share, turnover or profit organizations have to incorporate those concepts in their strategies. The outside environment is very unstable and things are evolving very fast so managers from all levels have to acknowledge the importance of change and to identify as soon as possible several new ideas that should be the subject of different change processes. Openness to organizational change has become a mandatory feature for those organizations that want to survive and adapt to the external pressure, helping them to be efficient. Even if in many cases managers are the initiators of change, this process is very complex and needs support and involvement from all the members of the organization, so the employee's attitude and commitment to change is crucial. In many cases employees have a negative attitude towards change and manifest a strong resistance, due to the fact that they are not consulted and are not involved in the process of the identification for the need of change. Without understanding and knowing very well what it is expected from them, employees are afraid of the unknown and prefer to perform their tasks as they did before. Creating a climate and a culture for change is very important, because like this change will be something normal, continuous and people will feel comfortable with any change initiatives, without being surprised, confused or scared. Even if any change process should improve the current state of the organization, sometimes change efforts fail because the ones that resist change are stronger than the ones supporting change. The purpose of this paper is to analyze how often are Romanian employees involved in the processes of change and how important is the role they play. We have also tried to see the Romanian manager

    2017-01-01

    Background Participatory research approaches have been introduced to meet end-users’ needs in the development of health promotion interventions among children. However, whereas children are increasingly involved as passive informants in particular parts of research, they are rarely involved as partners, equal to adult researchers, throughout the research process. This is especially prominent in the context of child health where the child is commonly considered to be vulnerable or when the research concerns sensitive situations. In these cases, researchers and gatekeepers to children’s involvement base their resistance to active involvement of children on potential adverse effects on the accuracy or quality of the research or on ethical or moral principles that participation might harm the child. Thus most research aimed at developing health promotion interventions for children in health care is primarily based on the involvement of parents, caregivers, and other stakeholders. Objective The objective of this paper is to discuss reasons for involving children in health promotive research and to explore models for children’s participation in research as a basis for describing how researchers can use design methodology and participatory approaches to support the participation and contribution of children in a vulnerable context. Methods We developed and applied a model for children's participation in research to the development of a digital peer support service for children cancer survivors. This guided the selection of appropriate research and design methodologies (such as interviews, focus groups, design sessions, and usability evaluation) for involving the children cancer survivors (8-12 years) in the design of a digital peer support service. Results We present a model for what children’s participation in research means and describe how we practically implemented this model in a research project on children with cancer. This paper can inform researchers in

  15. Community involvement in health services at Namayumba and Bobi health centres: A case study

    2014-01-01

    Full Text Available Background: Community involvement has been employed in the development of both vertical and horizontal health programmes. In Uganda, there is no empirical evidence on whether and how communities are involved in their health services.Aim and Setting: The aim of this study was to establish the existence of community involvement in health services and to identify its support mechanisms in Namayumba and Bobi health centres in Wakiso and Gulu districts, respectively.Methods: Participants were selected with the help of a community mobiliser. Key informants were selected purposively depending on their expertise and the roles played in their respective communities. The focus group discussions and key informant interviews were audio-recorded and transcribed verbatim. The transcripts were analysed manually for emerging themes and sub-themes.Results: Several themes emerged from the transcripts and we categorised them broadly into those that promote community involvement in health services and those that jeopardise it. Easy community mobilisation and several forms of community and health centre efforts promote community involvement, whilst lack of trust for health workers and poor communication downplay community involvement in their health services.Conclusion: Community involvement is low in health services in both Namayumba and Bobi health centres.

    Full Text Available The aim of this study was to investigate the management of parental involvement in three multicultural schools in the Umlazi District in Durban, South Africa. A literature survey resulting in a theoretical framework on parental involvement in schools, multicultural schools, and the managing of parental involvement in schools has been done. The contextual background of schools in contemporary South Africa is depicted. A qualitative research design has been used. Focus group discussions have been conducted, with a total of thirty-three principals, teachers and parents. It has found that there is a low level of meaningful contact between school and parents. Apathy exists on the side of parents, low expectations on the side of principals and teachers, and an organisational structure facilitating parent-school interaction is lacking. In managing parental involvement in multicultural schools, school managers display a lack of intercultural sensitivity.

    2005-06-01

    Full Text Available Abstract Background Cross-cultural and international research are important components of public health research, but the challenges of language barriers and working with interpreters are often overlooked, particularly in the case of qualitative research. Methods A case-study approach was used to explore experiences of working with an interpreter in Bangladesh as part of a research project investigating women's experiences of emergency obstetric care. The case study Data from the researcher's field notes provided evidence of experiences in working with an interpreter and show how the model of interviewing was adapted over time to give a more active role to the interpreter. The advantages of a more active role were increased rapport and "flow" in interviews. The disadvantages included reduced control from the researcher's perspective. Some tensions between the researcher and interpreter remained hard to overcome, irrespective of the model used. Independent transcription and translation of the interviews also raised questions around accuracy in translation. Conclusion The issues examined in this case study have broader implications for public health research. Further work is needed in three areas: 1 developing effective relationships with interpreters; 2 the impact of the interpreter on the research process; and 3 the accuracy of the translation and level of analysis needed in any specific public health research. Finally, this paper highlights the importance to authors of reflecting on the potential impact of translation and interpretation on the research process when disseminating their research.

    Full Text Available Abstract Objective: The present study was aimed at investigating bone involvement secondary to rotator cuff calcific tendonitis at ultrasonography. Materials and Methods: Retrospective study of a case series. The authors reviewed shoulder ultrasonography reports of 141 patients diagnosed with rotator cuff calcific tendonitis, collected from the computer-based data records of their institution over a four-year period. Imaging findings were retrospectively and consensually analyzed by two experienced musculoskeletal radiologists looking for bone involvement associated with calcific tendonitis. Only the cases confirmed by computed tomography were considered for descriptive analysis. Results: Sonographic findings of calcific tendinopathy with bone involvement were observed in 7/141 (~ 5% patients (mean age, 50.9 years; age range, 42-58 years; 42% female. Cortical bone erosion adjacent to tendon calcification was the most common finding, observed in 7/7 cases. Signs of intraosseous migration were found in 3/7 cases, and subcortical cysts in 2/7 cases. The findings were confirmed by computed tomography. Calcifications associated with bone abnormalities showed no acoustic shadowing at ultrasonography, favoring the hypothesis of resorption phase of the disease. Conclusion: Preliminary results of the present study suggest that ultrasonography can identify bone abnormalities secondary to rotator cuff calcific tendinopathy, particularly the presence of cortical bone erosion.

    An ultimate goal of investigations of rooibos plant material subjected to different stages of fermentation is to identify the chemical changes taking place in the phenolic composition, using an untargeted approach and chromatographic fingerprints. Realization of this goal requires, among others, identification of the main components of the plant material involved in chemical reactions during the fermentation process. Quantitative chromatographic data for the compounds for extracts of green, semi-fermented and fermented rooibos form the basis of preliminary study following a targeted approach. The aim is to estimate whether treatment has a significant effect based on all quantified compounds and to identify the compounds, which contribute significantly to it. Analysis of variance is performed using modern multivariate methods such as ANOVA-Simultaneous Component Analysis, ANOVA - Target Projection and regularized MANOVA. This study is the first one in which all three approaches are compared and evaluated. For the data studied, all tree methods reveal the same significance of the fermentation effect on the extract compositions, but they lead to its different interpretation.

    This paper examines the mission, structure and outputs of one organisation, the Student Platform for Engineering Education Development (SPEED), as a case study for how student-led organisations can use student involvement to promote and sustain student self-efficacy in an academic field. SPEED attracts young people to engineering through student participation in engineering education (EE). SPEED is a global, non-profit student organisation that functions as an interdisciplinary network to diversify dialogue, stimulate change and impact the development of EE and its effect on society. SPEED is directly attracting young people to engineering in various ways: the organisation of its keynote event, the Global Student Forum; facilitating interactions between globally minded, socially inclined engineers with aspirations to change the world; and through the global dissemination of SPEED's work and practices through broad and relevant channels. Short-term outcomes are highlighted here. This case study can serve as a model for student engagement and involvement in other disciplines.

  4. The timing of drug funding announcements relative to elections: a case study involving dementia medications.

    Directory of Open Access Journals (Sweden)

    Sudeep S Gill

    Full Text Available BACKGROUND: Following initial regulatory approval of prescription drugs, many factors may influence insurers and health systems when they decide whether to add these drugs to their formularies. The role of political pressures on drug funding announcements has received relatively little attention, and elections represent an especially powerful form of political pressure. We examined the temporal relationship between decisions to add one class of drugs to publicly funded formularies in Canada's ten provinces and elections in these jurisdictions. METHODS: Dates of provincial formulary listings for cholinesterase inhibitors, which are drugs used to treat Alzheimer's disease and related dementias, were compared to the dates of provincial elections. Medical journal articles, media reports, and proceedings from provincial legislatures were reviewed to assemble information on the chronology of events. We tested whether there was a statistically significant increase in the probability of drug funding announcements within the 60-day intervals preceding provincial elections. RESULTS: Decisions to fund the cholinesterase inhibitors were made over a nine-year span from 1999 to 2007 in the ten provinces. In four of ten provinces, the drugs were added to formularies in a time period closely preceding a provincial election (P = 0.032; funding announcements in these provinces were made between 2 and 47 days prior to elections. Statements made in provincial legislatures highlight the key role of political pressures in these funding announcements. CONCLUSIONS: Impending elections appeared to affect the timing of drug funding announcements in this case study. Despite an established structure for evidence-based decision-making, drug funding remains a complex process open to influence from many sources. Awareness of such influences is critical to maintain effective drug policy and public health decision-making.

    Recent techniques and shifts in the environment are often foreseen as leading management accountants to adopt a business orientation. However, empirical evidence pointing to fundamental shifts in the roles played by management accountants remains relatively scarce. The authors explore this paradox and give sense to the various roles played by the management accounting function by focusing on how management accountants are involved in and endowed with authority in decision-making situations.

    2006-01-01

    Prior to implementing laws and policies regulating water, wildlife, wetlands, endangered species, and recreation, natural resource managers often solicit public input. Concomitantly, managers are continually seeking more effective ways to involve stakeholders. In the autumn of 1999, the Wyoming Game and Fish Department sought to develop a state management plan for its portion of the Yellowstone grizzly bear (Ursus arctos horribilis) population if it was removed from the federal threatened species list. A key aspect of developing this plan was the involvement of federal, state, and local agencies, representatives from nongovernmental organizations, and citizens. Wyoming wildlife managers asked researchers from the United States Geological Survey to demonstrate how the Legal-Institutional Analysis Model could be used to initiate this process. To address these needs, we conducted similar workshops for a group of state and federal managers or staffers and a broad group of stakeholders. Although we found similarities among the workshop groups, we also recorded differences in perspective between stakeholder groups. The managers group acknowledged the importance of varied stakeholders but viewed the grizzly bear planning process as one centered on state interests, influenced by state policies, and amenable to negotiation. The other workshops identified many stakeholders and viewed the decision process as diffuse, with many opportunities for entry into the process. These latter groups were less certain about the chance for a successful negotiation. We concluded that if these assumptions and differences were not reconciled, the public involvement effort was not likely to succeed.

    Full Text Available Most tourism activities excluding the e-tourism activities as matter of their nature (service taker and provider take place face to face between people. In addition tourism activities encourage bonding people both for tourists and the tourism services providers. Tourism creates cohesion for many different cultural groups. One of the cities in Turkey, Izmir is a good example with including too many culturally oriented groups such as Levantines, Greek, Jewish, rarely Armenians. In this paper there are two research questions are hold; how is being the other (ethnic minority as tourism entrepreneurs in tourism industry in Izmir and their involvement in sustainable tourism development is investigated and if tourism activities help connecting different cultural groups together and closer is investigated. So regarding these research questions, the research methodology in this paper is qualitative. For that reason, semi structured interview technique is applied to people are belong to different cultural groups and identities whom entrepreneurs in tourism industry. Semi structured interview technique is a commonly used an interview method depending on providing deep understanding of participants` perceptions, thoughts and behaviors. In general, understanding of the other brings feeling respect to others` cultural beliefs and lifestyle and this will make peace and harmony to where they live together. As a result, with the light of these research questions being the other entrepreneurship in sustainable tourism development in Izmir is evaluated. Furthermore, in this research is tried to indicate the advantageous and disadvantageous and importance of different cultural groups for sustainable tourism development

Results. 45 RA patients and 45 Cs were evaluated. RA patients had 40% of bilateral and 17.8% unilateral alteration versus Cs with 22.2% bilateral and 4.4% unilateral alteration versus Cs with 22.2% bilateral and 4.4% unilateral in AC audiometry. In conventional T (CT) As-type curves in patients with RA, there were 22 LE (48.8%) and 26 RE (57.7%) versus Cs, there were16 RE (35.5%) and 20 LE (44.4%). In High-frequency T (HFT): the 3B1G pattern in RA more frequent versus Controls (Cs) in RE (P = .002 and LE (P = .01). There were no differences according to RA activity or RA disease evolution. Conclusions. There is a greater tendency of auditive loss of As curves in CT (rigidity in ossicular chain) and of the 3B1G pattern in HFT in RA. PMID:22482066

    The expanding production of bioenergy crops may impact regional air quality through the production of volatile organic compounds such as isoprene. To investigate the effects of isoprene-emitting crops on air quality, specifically ozone (O(3)) and secondary organic aerosol (SOA) formation, we performed a series of model runs using the Weather Research and Forecasting model with Chemistry (WRF/Chem) coupled with the Model of Emissions of Gases and Aerosols from Nature (MEGAN) simulating a proposed cropland conversion to the giant cane Arundo donax for biomass production. Cultivation of A. donax in the relatively clean air of northeastern Oregon resulted in an average increase in 8 h O(3) levels of 0.52 ppb, while SOA was largely unaffected (<+0.01 μg m(-3)). Conversions in U.S. regions with reduced air quality (eastern Texas and northern Illinois) resulted in average 8 h O(3) increases of 2.46 and 3.97 ppb, respectively, with daily increases up to 15 ppb in the Illinois case, and daytime SOA increases up to 0.57 μg m(-3). While cultivation of isoprene-emitting bioenergy crops may be appropriate at some scales and in some regions, other areas may experience increased O(3) and SOA, highlighting the need to consider isoprene emissions when evaluating potential regional impacts of bioenergy crop production.

    2010-08-01

    This paper examines the mission, structure and outputs of one organisation, the Student Platform for Engineering Education Development (SPEED), as a case study for how student-led organisations can use student involvement to promote and sustain student self-efficacy in an academic field. SPEED attracts young people to engineering through student participation in engineering education (EE). SPEED is a global, non-profit student organisation that functions as an interdisciplinary network to diversify dialogue, stimulate change and impact the development of EE and its effect on society. SPEED is directly attracting young people to engineering in various ways: the organisation of its keynote event, the Global Student Forum; facilitating interactions between globally minded, socially inclined engineers with aspirations to change the world; and through the global dissemination of SPEED\\'s work and practices through broad and relevant channels. Short-term outcomes are highlighted here. This case study can serve as a model for student engagement and involvement in other disciplines. © 2010 SEFI.

    2014-04-01

    Full Text Available The incidence of aortic disruption secondary to blunt abdominal trauma is rarely reported in the pediatric population. In general, most of the cases described are the result of motor vehicle accidents. We report on the treatment and outcomes of a 5-year-old child with aortic bifurcation disruption secondary to an unusual case of blunt abdominal trauma who was admitted to the emergency room in hypovolemic shock and subjected to immediate exploratory laparotomy and vascular repair. The mechanical forces involved in aortic disruption and the management options for repair and treatment of this injury will be discussed.

    2017-01-01

    Progression to severe organ involvement due to dengue infection has been associated with severe dengue disease, intensive care treatment, and mortality. However, there is a lack of understanding of the impact of pre-existing comorbidities and other risk factors of severe organ involvement among dengue adults. The aim of this retrospective case-control study is to characterize and identify risk factors that predispose dengue adults at risk of progression with severe organ involvement. This study involved 174 dengue patients who had progressed with severe organ involvement and 865 dengue patients without severe organ involvement, matched by the year of presentation of the cases, who were admitted to Tan Tock Seng Hospital between year 2005 and 2008. Age group of 60 years or older, diabetes, cardiac disorders, asthma, and having two or more pre-existing comorbidities were independent risk factors of severe organ involvement. Abdominal pain, clinical fluid accumulation, and hematocrit rise and rapid platelet count drop at presentation were significantly associated with severe organ involvement. These risk factors, when validated in a larger study, will be useful for triage by clinicians for prompt monitoring and clinical management at first presentation, to minimize the risk of severe organ involvement and hence, disease severity.

    2011-01-01

    In recent years, the Taiwanese government has strongly promoted the concept of ecological engineering in the hope that doing so will encourage the maintenance of the ecosystem and its integrity. As a result, the riprap spur dike is one of the most commonly used measures for protecting stream banks. Traditionally, a spur dike is used at concave banks to prevent their scouring and/or to increase their stabilization. An additional benefit of deflector structures, like spur dikes, may be to increase the weighted usable area (WUA) for aquatic life survival during periods of increased flow (examples include typhoon, flood, etc.). A two-dimensional river habitat simulation program (River2D) coupled with a developed shallow water habitat type diversity module was used for the case study at a headwater stream in central Taiwan. The habitat suitability index for this study was established using substrate, depth, and velocity from field surveys for the fish family Cyprinidae by prepositioned area electrofisher. The ungauged flood conditions were calculated using digital elevation models within a watershed delineation and hydrological modeling system in accordance with local regulations. Simulated results indicate that the spur dikes currently in use on the stream in this study need be improved from a WUA point of view more effectively handle a flood event.

    2010-01-01

    Experience shows that to achieve a successful implementation of EHR clinicians must obtain joint ownership of the decisions made during the EHR-process. The EHR planning process in the Region of North Jutland, Denmark was studied with the aim of answering the question; "Why are not all Danish physicians overjoyed by the introduction of EHR? A case study was carried out from Oct. 2003 till April 2006 using process analysis. The EHR project management's strategy meant that there was no workload reduction. This was seen as one of the main barriers for the physicians to achieve real influence. History shows that clinician's on the one hand and administrators on the other have different perceptions of the purpose of the patient record and that they both have struggled to influence this definition. To date, the administrators have won the battle. This was the major reason for the approach chosen for the EHR planning process in North Jutland, Denmark. It explains the conditions made available for the physicians, which led to their role being reduced to clinical consultants--rather than real participants.

    2014-01-01

    Full Text Available Sarcoidosis is a chronic granulomatous disease of unknown aetiology, which may involve any organ system. It most commonly occurs in adults with childhood involvement being rare. Central nervous system involvement is seen in up to 25% and typically involves meningeal disease resulting in multiple cranial neuropathies. Other common clinical findings include seizures, headache, dementia, and pituitary dysfunction. Imaging plays a central role in the diagnosis with typical findings including pachymeningeal and leptomeningeal enhancing lesions. Other imaging findings include lacunar and major territory infarcts, hypothalamic and infundibular thickening, hydrocephalus, and cranial nerve enhancement. We present a case of an eight-year-old male patient with progressive headache, visual disturbance, unilateral sensory hearing loss, and multiple cranial neuropathies. Imaging findings demonstrated the classic pachymeningeal and leptomeningeal enhancement along much of the skull base, as well as enhancement of the right and left second and eighth cranial nerves. Extensive inflammatory changes were noted in the temporal bones and paranasal sinuses. There was also enhancement of the right and left labyrinths. Sinus biopsy confirmed sarcoidosis. We present the first case to our knowledge of sarcoid labyrinthitis.

    The first part of the present study case has pointed to the efforts directed by Procter & Gamble over time to keep close to its customers and the manner in which management has supported innovation within the company. Following the principles of disruptive innovation, the CEO of the company has set the goal for the company as to produce at least 50% of the innovations from external ideas. So, the aim of this paper is to continue to analyse the tools and the approach that P&G has taken in order to launch new products by partnering with other companies. Innovating by collaborating with external entities holding a highly specialized level of technology and engineering knowhow has been appreciated to contribute to the value creation process. In order to understand how open innovation strategy has worked for Procter & Gamble and which was the designated tool used to enrich the company with valuable input in order to develop products, we have taken a look at P&G's open innovation platform Connect + Develop.

    Older adults benefit from unstructured, lifestyle-based activity that can be carried out in people's houses, neighbourhoods, and the built environment. Technological solutions may support physical activity and encourage wellbeing. To ensure such technology is suitable for, and usable by, older adults, it is crucial they are involved in all stages of design. Participatory design methodologies facilitate collaboration and engagement with potential users. We examine the suitability of participatory design for collaborating and engaging with older adults. Participatory design workshops were conducted with 33 older adults in the UK with the aim of designing mobile applications to support and promote physical activity and wellbeing in the built environment. As well as summarising the outcome of these workshops, the paper outlines several methodological issues relating to the suitability of participatory design for involving older adults in the technology design process.

    It has been suggested that alteration in the muscarinic-cholinergic system is involved in modulation of mood. Three studies have reported linkage on chromosome 7 with major depressive disorder (MDD) in or close to a region containing the muscarinic receptor CHRM2 gene. A haplotype of SNPs located in CHRM2 (rs1824024-rs2061174-rs324650) has been significantly associated with MDD in a previous study. We report the first study investigating this gene in a large, adequately powered, clinical depression case-control sample (n = 1420 cases, 1624 controls). Our data fail to support association with the CHRM2 polymorphisms previously implicated in the genetic aetiology of depression. It is possible our failure to replicate may be a consequence of differences in definition of the MDD phenotype and/or ethnic differences.

    2014-01-01

    Full Text Available This paper proposes recommendations for improving the implementation of a Project Management Office (PMO in a government organization. Such organizations can face uncertainties due to unpredicted and unexpected environmental events. The methodology used here was based on review of the literature, experience of the authors, and analysis of the process to be employed to create a PMO in the Department of Municipal Water and Sewage Systems (SEMAE, Brazil. This study aims to show how implementing a PMO can ensure proper management of strategic projects related to conservation of water resources. The PMO plays an important role in the implementation of strategic projects for public sanitation. This study also shows that the effectiveness of actions taken by the PMO is strongly influenced by how this process is implemented.

    The purpose of this study was to clinically evaluate the effectiveness of polytetrafluoroethylene membranes in the healing of interproximal Class II furcation defects in maxillary molars using a surgical treatment technique based on the principles of guided tissue regeneration. Eight subjects with similar bilateral Class II furcation lesions on the mesial aspect of maxillary first molars participated in this study. Patients received initial therapy consisting of oral hygiene instructions, scaling and root planing, and occlusal adjustment if necessary. Clinical parameters evaluated included plaque index, sulcular bleeding index, probing depth, attachment level, gingival recession, and open horizontal and vertical furcation fill. An acrylic occlusal stent was used to assure reproducibility of measurements. Experimental sites received a polytetrafluoroethylene membrane following surgical exposure of the furcation. Control sites were treated in the exact same manner but without a membrane. Membranes were removed at 6 weeks after the first surgery. Reentry surgeries were performed at 9 months. Postsurgical results showed a significant improvement in probing depth, attachment level, and open horizontal furcation fill for both groups when compared to baseline values, with experimental sites performing significantly better than controls. Control sites showed a slight loss in open vertical furcation fill while experimental sites remained unchanged. This study suggests that guided tissue regeneration using polytetrafluoroethylene membranes is of some but limited value in the treatment of maxillary molar interpoximal Class II furcation lesions.

    Noninvasive techniques for nail imaging would be useful for confirming diagnosis and monitoring treatment response at the microscopic level in patients with nail psoriasis. However, the use of ultrasound and high-resolution magnetic resonance imaging in nail evaluation is limited. Optical coherence tomography (OCT) produces high-resolution images of transversal tissue sections and represents an optimal approach to the study of the nail. This study used a multibeam OCT instrument to produce speckled variance OCT (SV-OCT) blood-flow images, which were used to measure the degree of change over successive scans. Nail changes, inflammation and response to therapy were evaluated in a 75-year-old female patient with psoriasis who had severe acrodermatitis continua of Hallopeau of the hands, treated for 4 weeks with 40 mg adalimumab (administered subcutaneously every other week) and 25 mg prednisone (administered orally, daily). SV-OCT provided a detailed assessment of the nail structures in relation to inflammation of psoriatic tissues. Restoration of the normal anatomy of the nail apparatus was apparent following adalimumab treatment; SV-OCT evaluation correlated with clinical appearance. SV-OCT may have a diagnostic role and provide an objective tool to assess clinical and subclinical inflammation in nail psoriasis.

    Disturbances in glutamate signaling caused by disruption of N-methyl-D-aspartate-type glutamate receptor (NMDAR) have been implicated in schizophrenia. Findings suggested that miR-219, miR-132 and miR-107 could involve in NMDAR signaling by influencing the expression of pathway genes or the signaling transmission and single nucleotide polymorphisms (SNPs) within miRNA genes or miRNA target sites could result in their functional changes. Therefore, we hypothesized that SNPs in miRNAs and/or their target sites were associated with schizophrenia. 3 SNPs in hsa-pri-miR-219/132/107 and 6 SNPs in 3'UTRs of GRIN2A/2B/3A and CAMK2G were selected and genotyped in a case-control study of 1041 schizophrenia cases and 953 healthy controls in Chinese Han population. In the present study, GRIN2B rs890 showed significant associations with schizophrenia. Further functional analyses showed that the rs890 variant C allele led to significantly lower luciferase activity, compared with the A allele. MDR analysis showed that a 4-locus model including rs107822, rs2306327, rs890 and rs12342026 was the best model. These findings suggest that GRIN2B may be associated with schizophrenia and interaction effects of the polymorphisms in hsa-miR-219, CAKM2G, GRIN2B and GRIN3A may confer susceptibility to schizophrenia in the Chinese Han population.

  17. The involvement of family in child protection cases in Iceland

    Anni Haugen

    2015-07-01

    Full Text Available The aim of this study is to examine the involvement of families in child protection cases in Iceland, as well as to shed light on the attitudes of child protection workers on the importance of including families while working on child protection cases. The study is part of an international comparative analysis called: Social Work with Families: Social Workers’ Constructions of Family in Professional Practice. This article only addresses the Icelandic segment of the research. In the study, qualitative methods were used and three focus groups were conducted, in which the same three-step vignette about a child protection case was presented. The findings highlighted how difficult child protection workers found it to define the family. The main element is that family are those individuals closest to the child and connected to them through emotional ties, as Icelandic child protection workers seem to strive to involve family in child protection cases. However, there are signs which show that when working with more complicated cases the definition of a family becomes narrower, and involvement is restricted mostly to parents and grandparents. The findings also show that attitudes toward fathers differ from those toward mothers. The mother is expected to support and create security for the child, while the father is judged mostly on his violent behaviour and is not automatically regarded as providing support or actively taking responsibility for his child.

  18. Land resources allocation strategies in an urban area involving uncertainty: a case study of Suzhou, in the Yangtze River Delta of China.

    2014-05-01

    A large number of mathematical models have been developed to support land resource allocation decisions and land management needs; however, few of them can address various uncertainties that exist in relation to many factors presented in such decisions (e.g., land resource availabilities, land demands, land-use patterns, and social demands, as well as ecological requirements). In this study, a multi-objective interval-stochastic land resource allocation model (MOISLAM) was developed for tackling uncertainty that presents as discrete intervals and/or probability distributions. The developed model improves upon the existing multi-objective programming and inexact optimization approaches. The MOISLAM not only considers economic factors, but also involves food security and eco-environmental constraints; it can, therefore, effectively reflect various interrelations among different aspects in a land resource management system. Moreover, the model can also help examine the reliability of satisfying (or the risk of violating) system constraints under uncertainty. In this study, the MOISLAM was applied to a real case of long-term urban land resource allocation planning in Suzhou, in the Yangtze River Delta of China. Interval solutions associated with different risk levels of constraint violation were obtained. The results are considered useful for generating a range of decision alternatives under various system conditions, and thus helping decision makers to identify a desirable land resource allocation strategy under uncertainty.

  19. Co-Producing Sustainability: Involving Parents and Civil Society in the Governance of School Meal Services. A Case Study from Pisa, Italy

    Directory of Open Access Journals (Sweden)

    Francesca Galli

    2014-03-01

    Full Text Available There is a rising awareness of the power of the public sector in enhancing sustainable consumption and production practices, in particular related to food procurement and its social, ethical, economical and environmental implications. School meal services have a high resonance in the debate on collective catering services because of the implications on the education to sustainable dietary habits and the orientation of the production system. This contribution focuses on the reciprocal relationship between professionals and users of school meal services as a driver to mobilize new resources—according to the theory of co-production—that steer service innovation and a shift towards more sustainable practices. We illustrate this through a case study on the school meal system in Pisa (Italy, where the Canteen Committee represents an institutional arena for participation and empowerment of actors that has gradually gained a central role in shaping this school meal service. Despite the challenges and obstacles, the institutionalized co-production of services allows consolidation of trust among key players and the introduction of innovations in the service, in the form of several projects oriented to sustainability which would not take place without the joint effort of actors involved, parents in the first place.

    Full Text Available Pseudoxanthoma elasticum (PXE is a rarely seen connective tissue disease which is characterized by progressive fragmentation and calcification of elastic fibers. Generally it is characterized by cutaneus, ocular and vascular system involvement and neurological complications are usually secondary to vascular insufficiency. 43 years old male patient had a progressive dysarthria, ataxia and vision loss which started many years ago referred to our clinic. Loose skin was seen on bilateral his axillar region and neck with atrophic, pale viola macular lesions on his body. There was “angiloid streaks” on fundus examination and skin biopsy showed calcified degenerated elastic fibers on middle and deep dermis. Diffuse white matter lesions were determined on cranial imaging. To keep in mind the diagnosis of rare diseases would be helpful in early diagnosis and treatment, reducing and even preventing systemic complications.

    Full Text Available The current study focuses on the impact of parent’s socioeconomic status on parental involvement in their child’s education at home. Forty Indian students studying in one the best performance- based National Type Tamil Schools in the state of Kedah, Malaysia were chosen based on purposive sampling. The sample comprised 10 students from Year Two, 10 students from Year Three, 10 students from Year Four and 10 students from Year Five. Those were the high achievement students identified based on the previous final year school examination results. Questionnaires were used by the researcher to obtain quantitative data related to the parent’s socioeconomic background and their involvement strategies in their children’s education at home from the students’ parent. In addition, in-depth interviews with twenty students, that is, five students from each Year were conducted to gather information on their parent’s involvement. The findings of this study indicate that most parents are from a higher socioeconomic background and they show a high degree of involvement in most of the involvement strategies at home to ensure their child’s educational success. Moreover, the economic and academic capital among the middle-class parents serve to enhance their understanding and knowledge on the actual values that need to be placed on their child’s education. As a result, these children gain in terms of good skills, behaviour and values, all of which are crucial to their academic success.

    Full Text Available Purpose: Brucellosis is a systemic disease that can affect many organs and tissues. Musculoskeletal system is one of the most commonly affected systems. Disease may present itself with sacroiliitis, peripheral arthritis, spondylitis, paraspinal abscess, bursitis or osteomyelitis. The objective of the present study was to determine the frequency, types and clinical features of osteoarticular involvement among cases with brucellosis in Konya city and to establish the differences between patients with and without osteoarticular involvement. Material and Methods: Three hundred and sixteen patients with Brucellosis who presented between June 2003 and June 2014 were included in the study. Brucellosis was diagnosed by positive Brucella Standard Agglutination Test ( and #61619;1/160 titer and/or growth of Brucella spp. in blood culture in addition to the presence of clinical signs and findings. Diagnosis of osteoarticular system complications was established by physical examination and radiological findings obtained by diagnostic imaging tools. Magnetic resonance images of the thoracic, lumbar or sacral vertebrae were acquired in patients with back pain, low back pain and sacro-iliac joint pain. Results: Osteoarticular involvement was noted in 129 patients (40.8% (females: 52% and males: 48%. The most common route of transmission was employment in farming and/or consumption of un-pasteurized milk or dairy products, especially fresh cheese, in 97 (75% cases. Mean age was 46 and #61617;18 years. Sacroiliitis was the most frequent osteoarticular involvement (n: 68, 52.7%, 70.5% of which were bilateral.

    Cancer is the second most important non-communicable disease worldwide and disproportionately impacts low- to middle-income countries. Diet in combination with other lifestyle habits seems to modify the risk for some cancers but little is known about South Americans. Food habits of Argentinean men pre- and post-diagnosis of prostate cancer (n = 326) were assessed along with other lifestyle factors. We studied whether any of the behaviors and risk factors for prostate cancer were found in men with other cancers (n = 394), compared with control subjects (n = 629). Before diagnosis, both cases reported a greater mean consumption of meats and fats and lower intakes of fruits, green vegetables, cruciferous vegetables, legumes, nuts, seeds, and whole grains than the controls (all p < 0.001). After diagnosis, cases significantly reduced the intake of meats and fats, and reported other dietary modifications with increased consumption of fish, fruits (including red fruits in prostate cancer), cruciferous vegetables, legumes, nuts, and black tea (all p < 0.001). Additional lifestyle aspects significantly predominant in cases included a reduced quality of sleep, emotional stress, low physical activity, tobacco smoking, alcohol consumption, living in rural areas, and being exposed to environmental contaminants. Argentinian men were predisposed to modify their unhealthy dietary habits and other lifestyle factors after cancer diagnosis. PMID:27409631

    A case of the Sotos syndrome associated with peripheral nerve involvements was reported. A 52-year-old male was admitted to Kawasaki Medical School Hospital because of gait disturbance, muscle atrophy, and weakness in both hands. This case was diagnosed as the Sotos syndrome based on the following symptoms and findings, acromegaloid features, hypertrophic changes in the hands and feet, a history of epileptic episodes, a low IQ, a normal growth hormone value, and no tumor lesion in the pituitary gland. Radiological examination disclosed a cauliflower-like appearance of the finger tips and thickness of the heel pads. Brain CT and MRI revealed diffuse mild brain atrophy. An electroencephalogram showed diffuse theta waves with sharp waves in the right parietal region. A needle electromyogram revealed neurogenic change in both upper and lower limbs. A nerve conduction study disclosed the carpal tunnel syndrome and cubital tunnel syndrome. These findings suggest that, as in the case of acromegaly, entrapment neuropathy and peripheral neuropathy can also be induced in the Sotos syndrome.

    Public parks provide many benefits to the community as the representatives of green area. The allocation of public places plays an extremely important role in the daily lives of inhabitants especially for recreational use that could enhance the quality of life of residents in the vicinity. To understand park users' behavior is one of the most important prerequisites for assessing the participation in public service from the park users' point of view. The pattern of park utilization on location and activity selection are important elements in behavioral study, while the public parks topograph may also influence the typical user's behavior. Questionnaire survey on park utilization was used to investigate the interaction between activity involvement and recreational location with the use of linear discriminant analysis (LDA) model. The study found that public park users' behavior is influenced not only by social characteristics but also by the recreational activities and their specific location characteristics. We found that about 45 percent of park visitors are local residents living within a radius of 3 km preferred travel to parks near their residential area. This implies that location selection behavior is correlated with travel distance, travel time and travel cost. Visit frequencies and on site expenditures reflect the recreation behavior for different type of activities. The overall information can be usefully applied by decision makers to launch appropriate public policy in consistence with the useful results of this study.

    Full Text Available BACKGROUND Diphtheria still endemic in many developing countries and is responsible for high case fatality. Myocardial involvement is a serious complication of diphtheria and diphtheria myocarditis frequently complicated by arrhythmias causes sudden death if not managed properly. So, early and adequate administration of Anti-Diphtheritic Serum (ADS and frequent monitoring particularly 24 hrs. ECG monitoring is helpful to detect any serious cardiac arrhythmias. METHODS A prospective study on patients who were culture positive diagnosed on the basis of WHO definition were treated and analysed in respect to homographic details, immunisation strategy, and clinical features with particular attention to myocarditis. RESULTS In the study, common age group affected by diphtheria was 5 to 10 years. Incidence of myocarditis more in same age group. Out of 64 patients with myocarditis, 23 patients died. CONCLUSION Incidence of diphtheria has increased in the recent years. Commonly effected age group is 5 to 10 years and most of them are presented with asymptomatic myocarditis. Symptomatic diphtheritic myocarditis has high mortality rate even with aggressive management. Patient who presented with either LBBB alone are with combination of other conduction of abnormalities has high mortality rate.

    Full Text Available Mycoplasma synoviae (MS is an important pathogen of poultry worldwide, causing respiratory tract infection and infectious synovitis in chickens and turkeys. The study was designed to detect M. synoviae through serology, culture isolation and polymerase chain reaction (PCR assay to document the involvement of MS infection in respiratory distress cases of broiler birds. The validated PCR assay amplifying the conserved gene region of 16SrRNA gene was applied for the detection of M. synoviae from culture as well as in clinical samples. The results indicated that 04 out of total 17 commercial broiler flocks showing respiratory distress signs were found positive with M. synoviae infection indicating 76.57% sero-positivity as, determined with rapid serum agglutination (RSA test. Out of 85 clinical specimens (collected from sero-positive birds; M. synoviae culture isolation was successfully attained in 36 (42.35% samples. Whereas, PCR test has detected 84 (98.82% positive cases. The prevalence of MS in broiler birds was observed maximum as measured through PCR. It is suggested that the true prevalence of MS may best be reflected by combining RSA and PCR test findings.

    2015-06-01

    Lucas Cranach the Elder (LCE) (1472-1553) maintained an organized and highly efficient workshop, served as councilor in Wittenberg from 1519-1544, established a publishing house in 1520, held a pharmacy from 1520, and served as mayor of Wittenberg from 1537 to 1543. He was known as the 'swiftest of painters,' resulting in 1,000 surviving panel paintings, canvas paintings, drawings, and etchings in a career that spanned 53 years (1500-1553). Facing this astoundingly enormous oeuvre, the question that this paper seeks to answer is unavoidable: what was LCE's involvement in this oeuvre, which most is still attributed to him, in light of his many other time-consuming engagements? To answer this question, this paper becomes a study of stylistic comparisons of LCE's oeuvre, in order to assess, analyze and identify his style to determine whether all of the works attributed to him were indeed his own handiwork. Classifying LCE's style, together with the fact that he ran his workshop in factory-like conditions, supplying his apprentices with pigments, designs they could trace, copies, modelling versions, and patterns, making him an artist turned businessman, LCE becomes an artist who turned art into an industrial operation, earning the title 'Cranach Inc.' The conclusion of this paper will be based inter-alia on comparisons between Infra-red images and the visible paintings, in order to undermine the established attributions made to LCE.

  8. The complex clinical issues involved in an athlete's decision to retire from collision sport due to multiple concussions: a case study of a professional athlete

    Directory of Open Access Journals (Sweden)

    Andrew eGardner

    2013-09-01

    Full Text Available The issue of retirement from athletic participation due to repetitive concussive injuries remains controversial. The complexity of providing recommendations to elite athletes is highlighted by the prospect that offering inappropriate advice may foreseeably lead to engagement in a medico-legal challenge. Currently no evidenced-based, scientifically validated guidelines for forming the basis of such a decision exist. The current paper discusses the complexities of this challenge in addition to presenting a case study of a professional athlete. A number of central issues to consider when discussing athlete retirement revolve around the player’s medical and concussion histories, the current clinical profile, the athlete’s long-term life goals and understanding of the potential long-terms risks. Ensuring that thorough investigations of all possible differential diagnosis, that may explain the presenting symptoms, are conducted is also essential. Discussion pertaining to recommendations for guiding the clinical approach to the retirement issue for athletes with a history of multiple concussions is presented.

    Root activities in terms of respiration and non-structural carbohydrates (NSC) storage and mobilization have been suggested as major physiological roles in fine root lifespan. As more frequent heat waves and drought periods within the next decades are expected, to what extent does thermal acclimation in fine roots represent a mechanism to cope with such upcoming climatic conditions? In this study, the possible changes in very fine (diameter Fagus sylvatica saplings subjected to a simulated long-lasting heat wave event and to co-occurring soil drying. For both very fine and fine roots, soil temperature (ST) resulted inversely correlated with specific root length, respiration rates and SSs concentration, but directly correlated with root mass, root tissue density and starch concentration. In particular, starch concentration increased under 28 °C for successively decreasing under 21 °C ST. These findings showed that thermal acclimation in very fine and fine roots due to 24 days exposure to high ST (∼ 28 °C), induced starch accumulation. Such 'carbon-savings strategy' should bear the maintenance costs associated to the recovery process in case of restored favorable environmental conditions, such as those occurring at the end of a heat wave event. Drought condition seems to affect the fine root vitality much more under moderate than high temperature condition, making the temporary exposure to high ST less threatening to root vitality than expected.

    Clustered regularly interspaced short palindromic repeats interference (CRISPRi) is used to edit eukaryotic genomes. Here, we show that CRISPRi can also be used for fine-tuning prokaryotic gene expression while simultaneously regulating multiple essential gene expression with less labor and time consumption. As a case study, CRISPRi was used to control polyhydroxyalkanoate (PHA) biosynthesis pathway flux and to adjust PHA composition. A pathway was constructed in Escherichia coli for the production of poly(3-hydroxybutyrate-co-4-hydroxybutyrate) [P(3HB-co-4HB)] from glucose. The native gene sad encoding E. coli succinate semi-aldehyde dehydrogenase was expressed under the control of CRISPRi using five specially designed single guide RNAs (sgRNAs) for regulating carbon flux to 4-hydroxybutyrate (4HB) biosynthesis. The system allowed formation of P(3HB-co-4HB) consisting of 1-9mol% 4HB. Additionally, succinate, generated by succinyl-coA synthetase and succinate dehydrogenase (respectively encoded by genes sucC, sucD and sdhA, sdhB) was channeled preferentially to the 4HB precursor by using selected sgRNAs such as sucC2, sucD2, sdhB2 and sdhA1 via CRISPRi. The resulting 4HB content in P(3HB-co-4HB) was found to range from 1.4 to 18.4mol% depending on the expression levels of down-regulated genes. The results show that CRISPRi is a feasible method to simultaneously manipulate multiple genes in E. coli.

    A 65-year old male presented with selective amyotrophy of the right lower limb which, after a progressive course of some months, had stabilized 12 years previously. Physical examination showed amyotrophy involving the gastrocnemius and the quadriceps extensor femoris without sensory impairment. EMG suggested motor neuron disease. This case meets Hirayama and Serratrice's criteria for benign chronic monomelic amyotrophy. We support the hypothesis of a casual vascular factor, as proposed by Hirayama.

    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.

  1. What is involved in medicines management across care boundaries? A qualitative study of healthcare practitioners' experiences in the case of acute kidney injury

    2017-01-01

    Objectives To examine the role of individual and collective cognitive work in managing medicines for acute kidney injury (AKI), this being an example of a clinical scenario that crosses the boundaries of care organisations and specialties. Design Qualitative design, informed by a realist perspective and using semistructured interviews as the data source. The data were analysed using template analysis. Setting Primary, secondary and intermediate care in England. Participants 12 General practitioners, 10 community pharmacists, 7 hospital doctors and 7 hospital pharmacists, all with experience of involvement in preventing or treating AKI. Results We identified three main themes concerning participants' experiences of managing medicines in AKI. In the first theme, challenges arising from the clinical context, AKI is identified as a technically complex condition to identify and treat, often requiring judgements to be made about renal functioning against the context of the patient's general well-being. In the second theme, challenges arising from the organisational context, the crossing of professional and organisational boundaries is seen to introduce problems for the coordination of clinical activities, for example by disrupting information flows. In the third theme, meeting the challenges, participants identify ways in which they overcome the challenges they face in order to ensure effective medicines management, for example by adapting their work practices and tools. Conclusions These themes indicate the critical role of cognitive work on the part of healthcare practitioners, as individuals and as teams, in ensuring effective medicines management during AKI. Our findings suggest that the capabilities underlying this work, for example decision-making, communication and team coordination, should be the focus of training and work design interventions to improve medicines management for AKI or for other conditions.

    2000-01-01

    In May 1991, at a Department of Energy (DOE) public hearing at Los Alamos, New Mexico, a local artist claimed there had been a recent brain tumor cluster in a small Los Alamos neighborhood. He suggested the cause was radiation from past operations of Los Alamos National Laboratory. Data from the Laboratory's extensive environmental monitoring program gave no reason to believe this charge to be true but also could not prove it false. These allegations, reported in the local and regional media, alarmed the community and revealed an unsuspected lack of trust in the Laboratory. Having no immediate and definitive response, the Laboratory offered to collaborate with the community to address this concern. The Los Alamos community accepted this offer and a joint Community-Laboratory Working Group met for the first time 29 days later. The working group set as its primary goal the search for possible carcinogens in the local environment. Meanwhile, the DOE announced its intention to fund the New Mexico Department of Health to perform a separate and independent epidemiological study of all Los Alamos cancer rates. In early 1994, after commissioning 17 environmental studies and meeting 34 times, the working group decided that the public health concerns had been resolved to the satisfaction of the community and voted to disband. This paper tells the story of the artist and the working group, and how the media covered their story. It summarizes the environmental studies directed by the working group and briefly reviews the main findings of the epidemiology study. An epilogue records the present-day recollections of some of the key players in this environmental drama.

    Full Text Available Neurofibromatosis (NF is often noticed at birth or soon after. NF is divided into two types: NF type 1 is a complex of cutaneous and deep neural tumors. It is an autosomal dominant familial disorder. CNS is affected in about 15% of the cases. Optic nerve gliomas have a high degree of association with NF 1."nNF type 2 is much less commonly seen. It is also inherited as an autosomal dominant trait. Bilateral acoustic neuromas are pathognomonic of NF 2 and may be associated with meningiomas or ependymo-mas."nTypical clinical manifestations of neurofibromatosis are cafe-au-lait spots and multiple cutaneous tumors. There are also bone involvement as scoliosis, pseudoarthrosis of long bones, scalloping of vertebral bodies, abnormal rib tubulation, and defective ossification of the posterior superior wall of the orbit."nExtraskeletal manifestations of neurofibromatosis include gliomas of the optic nerves, pheochromocytoma, aneurysms of cerebral and renal arteries, acoustic neurilemmoma and superficial skin nodular neurofibromas."nHere, we intend to present images of several cases of neurofibromatosis with different aspects of involvement of the body.

  5. Evaluating genotoxicity data to identify a mode of action and its application in estimating cancer risk at low doses: A case study involving carbon tetrachloride.

    Eastmond, David A

    2008-03-01

    In the new USEPA cancer risk assessment guidelines, mode of action (MoA) information, combined with a determination of whether or not a chemical is mutagenic, plays an important role in determining whether a linear or nonlinear approach should be used to estimate cancer risks at low doses. In this article, carbon tetrachloride (CT) is used as an example to illustrate how mixed genotoxicity data can be evaluated and used to identify a likely MoA. CT is essentially negative in inducing gene mutations in Salmonella, but is consistently positive in inducing recombination and aneuploidy in fungi. Negative or equivocal results were seen in most in vitro and in vivo studies in mammals, including mutation studies in transgenic mice. However, DNA adducts, primarily those derived from oxidation- and lipid-peroxidation-derived products as well as DNA double-strand breaks and micronucleated cells, have been seen repeatedly in the liver of CT-treated animals. On the basis of the weight of evidence, CT should not be considered a directly mutagenic agent. Mutagenic as well as other genotoxic effects, as they occur, will most likely be generated through indirect mechanisms resulting from oxidative and lipid peroxidative damage and/or damage occurring during necrosis or apoptosis. As key events in this process are expected to occur in a nonlinear fashion, the expected relationship between CT dose and carcinogenic response in the liver is likely to be nonlinear with a steep dose response. This conclusion is consistent with rodent cancer bioassay results in which steep nonlinear dose responses have been seen.

    Crohn's disease is well known to affect any part of the gastrointestinal tract including the oral cavity and anus.Various extraintestinal complications have been reported in Crohn's disease, but extraintestinal involvement characterized by granulomatous lesions is uncommon. Here, we have reported a case about the involvement of the gallbladder in Crohn's disease. A 33-year-old woman was diagnosed having panperitonitis due to intestinal perforation and cholecystitis. The patient was moved to the surgical service for an emergency operation. On the resected specimen, there was a broad longitudinal ulcer at the mesenteric side. The mucosa of the gallbladder was nodular and granular, and the wall was thickened.The surface epithelium of the gallbladder was partially eroded and pyloric gland metaplasia was observed focally. Rokitansky-Aschoff sinuses were also present.From the lamina propria to the subserosal layer, there were several well-formed epithelioid cell granulomas,which were the non-caseating sarcoidal type different from the foreign-body and xanthomatous granulomas.Periodic-acid Schiff and acid fast stains revealed no organism within the granulomas. Lymphoid aggregates were present throughout the gallbladder wall. Sections from the resected ileum showed typical features of the Crohn's disease. When cholecystectomy is performed in a patient with Crohn's disease, the possibility of gallbladder involvement should be carefully examined by histopathological tests.

    Two thirds of the congenital toxoplasmosis cases describe minimal or inapparent symptoms present at birth, being diagnosed from a psychomotor retard. The forms of chorioretinitis may be described by repeated outbursts in the first years of life. Chorioretinitis or focal necrotizing retinitis usually develops in a bilateral way, being progressive and leading to blindness. Usually there is only one focal inflammatory beginning at the edge of a pigmented scar and the local inflammatory process may extend through successive spikes in other regions of the retina. Active chorioretinitis is expressed clinically by a blurred misty eyesight, with the advent of scotomas, photophobia, and if the macula is involved, the loss of the central eyesight may occur. In this paper I present the patient R.A., 6 years old from Constanta who is hospitalized in the Clinic of Infectious Diseases for investigations and treatment continuity because positive IgG Toxoplasma was previously found. The child has spastic quadriplegia and profound mental retardation.

    Arteriovenous malformations (AVMs) comprising a feeding artery, nidus, and draining vein rarely develop in the gastrointestinal tract. Although almost all AVMs are asymptomatic, they cause massive painless rectal bleeding and subsequent chronic anemia. The definitive diagnosis of AVM is achieved by selective mesenteric angiography, and surgical resection is the treatment of choice. We detected an intestinal AVM involving the descending colon in a patient with severe hematochezia. The diagnosis was made by CT angiography performed using a 64-channel MDCT and the obtained 3D reconstruction images. The AVM showed an extensive vascular network on CT images, and it was treated by surgical resection. Here, we report this case of an intestinal AVM along with its imaging findings.

    Full Text Available Parental involvement in schools in an emerging democracy has gained significant attention among school administrators, educators, parents, local governments, and the international development community; yet, empirical data on this subject remains sparse. This study aims to examine the patterns of parental involvement in schools in Croatian communities. Using mixed-methods, the sample size consists of 294 elementary school parents, two focus groups (parents and teachers, and nine interviews with national and international stakeholders. The study found that, apart from the educational outcomes for children, parental involvement also may be an important platform through which parents can practice democratic behaviors and engage in community-building initiatives. Through school-related activities, parents learn to interact with a government institution, voice their interests, participate in decision-making, leverage and use power, and cooperate with each other and the community. Findings from this study can have implications for social work practice and social development assistance by recognizing how engaging parents in school-based activities can become a platform for community participation and democratic behavior.

    2008-05-01

    Full Text Available Angiosarcomas of bone are rare tumors constituting 1% of all malignant bone tumors. They can be either solitary or multifocal and can easily be misinterpreted as multiple myeloma or metastasis radiologically. We present a case of multifocal angiosarcoma arrising in foot bones, the diagnosis of which was difficult clinically, radiologically and pathologically. The histologic findings observed in both bioptic and amputation specimens were provided.The patient was a 56 years-old man who has undergone coronary by-pass and saphenous vein surgery 3 months ago. He has been suffering from pain and swelling on left foot since then. The lesion was suspicious for atypical fungal infection, metastasis or lymphoma radiologically. “Tru-cut” biopsy revealed extensive necrosis and the lesion resembled an inflammatory and reactive process at first glance. Morphologic mimickers of the lesion like lymphoma, metastasis and small round cell tumors were excluded immunohistochemically and the diagnosis of “malignant vasculary tumor” was made upon CD- 31 positivity of tumor cells, presence of erytrocytes, cells with intracytoplasmic lumina and increased mitotic activity. In amputation specimen a multifocal tumor having areas of necrosis and hemorrhages was observed involving predominantly calcaneus but also infiltrating talus, distal tibia and achilles tendon. The maximum diameter of tumor was 5 cm in calcaneus. Adjuvant chemotherapy could not be given because of cardiac problems.The case was presented to increase awareness on this rare, diagnostically problematic issue, the classification of which is controversial.

    New seismological monitoring networks combine broadband seismic receivers, hydrophones and micro-barometers antenna, providing complementary observation of source-radiated waves. Exploiting these observations requires accurate and multi-media - elastic, hydro-acoustic, infrasound - wave simulation methods, in order to improve our physical understanding of energy exchanges at material interfaces.We present here a new development of a high-order Hybridized Discontinuous Galerkin (HDG) method, for the simulation of coupled seismic and acoustic wave propagation, within a unified framework ([1],[2]) allowing for continuous and discontinuous Spectral Element Methods (SEM) to be used in the same simulation, with conforming and non-conforming meshes. The HDG-SEM approximation leads to differential - algebraic equations, which can be solved implicitly using energy-preserving time-schemes.The proposed HDG-SEM is computationally attractive, when compared with classical Discontinuous Galerkin methods, involving only the approximation of the single-valued traces of the velocity field along the element interfaces as globally coupled unknowns. The formulation is based on a variational approximation of the physical fluxes, which are shown to be the explicit solution of an exact Riemann problem at each element boundaries. This leads to a highly parallel and efficient unstructured and high-order accurate method, which can be space-and-time adaptive.A numerical study of the accuracy and convergence of the HDG-SEM is performed through a number of case studies involving elastic-acoustic (infrasound) coupling with geometries of increasing complexity. Finally, the performance of the method is illustrated through realistic case studies involving ground wave propagation associated to topography effects.In conclusion, we outline some on-going extensions of the method.References:[1] Cockburn, B., Gopalakrishnan, J., Lazarov, R., Unified hybridization of discontinuous Galerkin, mixed and

    be achieved through the use of objectivist case study research. The strength of the case study design is that it allows for uncovering or suggesting causal relationships in real-life settings through an intensive and rich collection of data. According to Hilliard (1993), the opposite applies for extensive...... designs, in which a small amount of data is gathered on a large number of subjects. With the richness of data, the intensive design is ―the primary pragmatic reason for engaging in single-case or small N research‖ (p. 374) and for working from an idiographic rather than a nomothetic perspective....

    Here we report three patients affected with neurodevelopmental disorders and harbouring 21q21 deletions involving NCAM2 gene. NCAM (Neural Cell Adhesion Molecule) proteins are involved in axonal migration, synaptic formation and plasticity. Poor axonal growth and fasciculation is observed in animal models deficient for NCAM2. Moreover, this gene has been proposed as a candidate for autism, based on genome-wide association studies. In this report, we provide a comprehensive molecular and phenotypical characterisation of three deletion cases giving additional clues for the involvement of NCAM2 in neurodevelopment.

    CNS dengue infection is a rare condition and the pattern of brain involvement has not been well described. We report the MR imaging (MRI) features in eight cases of dengue encephalitis. We retrospectively searched cases of dengue encephalitis in which imaging was performed. Eight cases (three men, five women; age range: 8-42 years) diagnosed with dengue encephalitis were included in the study. MR studies were performed on 3-T and 1.5-T MR clinical systems. Two neuroradiologists retrospectively reviewed the MR images and analysed the type of lesions, as well as their distribution and imaging features. All eight cases exhibited MRI abnormalities and the cerebellum was involved in all cases. In addition, MRI signal changes were also noted in the brainstem, thalamus, basal ganglia, internal capsule, insula, mesial temporal lobe, and cortical and cerebral white matter. Areas of susceptibility, diffusion restriction, and patchy post-contrast enhancement were the salient imaging features in our cohort of cases. A pattern of symmetrical cerebellar involvement and presence of microbleeds/haemorrhage may serve as a useful imaging marker and may help in the diagnosis of dengue encephalitis. (orig.)

  20. Who and What Does Involvement Involve? A Multi-Sited Field Study of Involvement of Relatives in Danish Psychiatry.

    Oute, Jeppe; Petersen, Anders; Huniche, Lotte

    2015-01-01

    This article gives an account of aspects of a multi-sited field study of involvement of relatives in Danish psychiatry. By following metaphors of involvement across three sites of the psychiatric system-a family site, a clinical site and a policy site-the first author (J.O.) investigated how, and on what grounds, involvement of relatives is perceived in Danish psychiatry. Paradoxically, the current understanding of involvement of relatives fails to take into consideration the perspectives of the relatives per se and families that were being studied. By analyzing involvement from a discourse theoretical perspective laid out by Ernesto Laclau and Chantal Mouffe, the aim of this study is to show how the dominant discourse about involvement at the political and clinical sites is constituted by understandings of mentally ill individuals and by political objectives of involvement. The analysis elucidates how a psycho-ideological discourse positions the mentally ill person as weak, incapable, and ineffective. By contrast, the supporting relative is positioned as a strong, capable, and effective co-therapist. Furthermore, the analysis considers how this dominant discourse of involvement is constituted by a broader discourse of neoliberalism and market orientation, which justifies involvement as a subtle institutionalization of social control. The article highlights that the role of the relative as a co-therapist may be contested by the families' discourse, which emphasizes issues concerning the responsibility toward the mental health of the ill individual as well as toward the psychological milieu of the family.

    Full Text Available Abstract Background Lateral epicondylitis is a common sports injury of the elbow caused due to altered muscle activation during repetitive wrist extension in many athletic and non-athletic endeavours. The amount of muscle activity and timing of contraction eventually is directly dependent upon joint position during the activity. The purpose of our study was to compare the grip strength in athletes with lateral epicondylalgia in two different wrist extension positions and compare them between involved and uninvolved sides of athletes and non-athletes. Methods An assessor-blinded case-control study of eight athletes and twenty-two non-athletes was done. The grip strength was measured using JAMAR® hand dynamometer in kilograms-force at 15 degrees (slightly extended and 35 degrees (moderately extended wrist extension positions (maintained by wrist splints on both involved and uninvolved sides of athletes and non-athletes with unilateral lateral epicondylitis of atleast 3 months duration. Their pain was to be elicited with local tenderness and two of three tests being positive- Cozen's, Mill's manoeuvre, resisted middle finger extension tests. For comparisons of grip strength, Wilcoxon signed rank test was used for within-group comparison (between 15 and 35 degrees wrist extension positions and Mann-Whitney U test was used for between-group (athletes vs. non-athletes comparisons at 95% confidence interval and were done using SPSS 11.5 for Windows. Results Statistically significant greater grip strength was found in 15 degrees (27.75 ± 4.2 kgms in athletes; 16.45 ± 4.2 kgms in non-athletes wrist extension than at 35 degrees (25.25 ± 3.53 kgm in athletes and 14.18 ± 3.53 kgm in non-athletes. The athletes had greater grip strength than non-athletes in each of test positions (11.3 kgm at 15 degrees and 11.07 kgm at 35 degrees measured. There was also a significant difference between involved and uninvolved sides' grip strength at both wrist

    Marshall, Sarah L; Crowe, Trevor P; Oades, Lindsay G; Deane, Frank F; Kavanagh, David J

    2007-03-01

    This Open Forum examines research on case management that draws on consumer perspectives. It clarifies the extent of consumer involvement and whether evaluations were informed by recovery perspectives. Searches of three databases revealed 13 studies that sought to investigate consumer perspectives. Only one study asked consumers about experiences of recovery. Most evaluations did not adequately assess consumers' views, and active consumer participation in research was rare. Supporting an individual's recovery requires commitment to a recovery paradigm that incorporates traditional symptom reduction and improved functioning, with broader recovery principles, and a shift in focus from illness to well-being. It also requires greater involvement of consumers in the implementation of case management and ownership of their own recovery process, not just in research that evaluates the practice.

    2015-12-01

    Full Text Available Paget’s disease is a common bone disorder which is characterized by excessive bone turnover. This condition rarely involves sternum, patella, scapula, hand, foot and facial bones. A 65-year-old male patient was admitted to our outpatient clinic with the complaint of right-sided pain that radiated from his groin to his knee for the last 5-6 years. His physical examination revealed limited hip movements and pain. Whole body bone scintigraphy detected diffuse, increased activity in the right coxa and entire scapula. Elevated alkaline phosphatase (ALP (367 U/L was observed in laboratory results. Further investigations and examinations were performed in order to exclude possible malignancies (eg. prostate, lung due to involvement of scapula which is atypical for Paget’s disease. Finally, poliostotic Paget’s disease with pelvic and scapular involvement was considered as the definite diagnosis. Treatment with risedronate sodium was started at a dose of 35 mg daily which led to marked improvement in hip pain and reduction in ALP level to 150 U/L after one month. While making a differential diagnosis of scintigraphic lesions at an unusual location such as scapula, consideration should be given to the fact that Paget’s disease may affect any bone in the body although this is rare

    Mycosis fungoides (MF) is the most common type of primary cutaneous T-cell lymphoma (CTCL), and folliculotropic MF (FMF) is one clinical variant of classic MF. MF generally has a good prognosis with an indolent clinical course, but for FMF greater therapeutic resistance is suggested. Visceral involvement is very rare in these two clinical forms. We report two exceptional cases of FMF with pulmonary and hepatic involvement. Five years after their initial diagnoses, patient 1 presented with a pulmonary localization of his FMF, and patient 2 with liver involvement, without lymph node or T-cell clones in the blood. These two patients had FMF corresponding to stage T2N0M1B0. These two cases highlight the aggressiveness of this rare variant of MF. They suggest that the T lymphocytes found in the folliculotropic form of CTCL could be characterized by greater visceral tropism. They raise the question of the molecular and functional characteristics of these T lymphocytes, and the possibility of a common target in the hair follicles and certain organs. Studies have shown that chemokine receptors are likely to be involved in the skin tropism that characterizes CTCL. These two cases show the aggressiveness of FMF and point to the interest in comparing the molecular characteristics of T lymphocytes in the folliculotropic and nonfolliculotropic forms of CTCL.

    Recovery from chikungunya is previously considered universal and mortality due to the virus is rare and unusual. Findings from recent chikungunya outbreaks occurred in Reunion Island and India have since challenged the conventional view on the benign nature of the illness. Malaysia has experienced at least of 4 outbreaks of chikungunya since 1998. In the present on-going large outbreak due to chikungunya virus of Central/East African genotype, a previous healthy sixty six years gentleman without co-morbidity was noted to have severe systemic infection by the virus and involvement of his liver. He subsequently passed away due to cardiovascular collapse after 5 days of illness.

    Full Text Available This case study was developed from an actual scenario by Dr. Steve Leybourne of Boston University.  The case documents the historical evolution of an organization, and has been used successfully in courses dealing with organizational and cultural change, and the utilization of ‘soft skills’ in project-based management. This is a short case, ideal for classroom use and discussion.  The issues are easily accessible to students, and there is a single wide ranging question that allows for the inclusion of many issues surrounding strategic decision-making, and behavioural and cultural change. Alpha was one of the earlier companies in the USA to invest in large, edge-of-town superstores, with plentiful free vehicle parking, selling food and related household products. Alpha was created in the 1950s as a subsidiary of a major publicly quoted retail group.  It started business by opening a string of very large discount stores in converted industrial and warehouse premises in the south of the United States. In the early days shoppers were offered a limited range of very competitively priced products. When Alpha went public in 1981 it was the fourth largest food retailer in the US, selling an ever-widening range of food and non-food products.  Its success continued to be based on high volume, low margins and good value for money, under the slogan of ‘Alpha Price.’

    A 62-year-old male suffering from vomiting and mild preceding nausea for 15 days was examined in the present case report. Magnetic resonance imaging revealed a homogeneously enhancing cluster-like lesion involving the lateral, third and fourth ventricles. An endoscopic biopsy was performed, and histopathological examination led to the diagnosis of a high-grade diffuse large B-cell lymphoma. To the best of our knowledge, the present study reports the first case of a primary lymphoma involving the entire ventricular system. Therefore, primary lymphomas should be considered in the list of ventricular tumors. An endoscopic biopsy requires minimal invasion to obtain an adequate tissue sample, and frequently leads to the correct diagnosis and subsequent treatment protocols. PMID:26889262

    Langerhans cell histiocytosis (LCH) is a proliferative disease of histiocyte-like cells, with a wide range of clinical presentations that vary from a solitary lesion to more severe multifocal or disseminated lesions. The disease can affect any age group; however, the peak incidence rate is in infants aged between 1 and 3 years-old. Diagnosis of LCH should be based on the synthetical analysis of clinical presentations, in addition to features of imaging and histopathology. Although certain cases regress spontaneously, other patients require systemic chemotherapy together with the administration of steroids. The present study reports the case of an infant with LDH with multisystem involvement, including that of the bone, skin, orbit, spleen and lungs. The patient received chemotherapy and obtained rapid improvement in the involved systems. A total of 2.5 years after completion of the therapy, the patient still remains in follow-up and no evidence of active disease has been noted. PMID:26136948

    Full Text Available Congenital heart disease (CHD affects the intricate structure and function of the heart and is one of the leading causes of death in newborns. The genetic basis of CHD is beginning to emerge. Our laboratory has been engaged in identifying mutations in genes linked to CHD both in families and in sporadic cases. Over the last two decades, we have employed linkage analysis, targeted gene sequencing and genome wide association studies to identify genes involved in CHDs. Cardiac specific genes that encode transcription factors and sarcomeric proteins have been identified and linked to CHD. Functional analysis of the relevant mutant proteins has established the molecular mechanisms of CHDs in our studies.

    2014-01-01

    Full Text Available Mucormycosis is an opportunistic fulminant fungal infection, which has the ability to cause significant morbidity and frequently mortality in the susceptible patient. Common predisposing factors include diabetes mellitus and immunosuppression. The infection begins in the nose and paranasal sinuses due to inhalation of fungal spores. The fungus invades the arteries leading to thrombosis that subsequently causes necrosis of the tissue. The infection can spread to orbital and intracranial structures either by direct invasion or through the blood vessels. Here we describe a case of mucormycosis of maxillary antrum extending to ethmoidal and frontal sinus and also causing necrosis of left maxilla in an uncontrolled diabetic individual to emphasize early diagnosis and treatment of this fatal fungal infection.

    Full Text Available Thyroglossal duct cyst presents most frequently in the midline of the neck, either at or just below the level of the hyoid bone. They generally manifest as painless neck swelling, and they move on protrusion of tongue and during swallowing. A case of thyroglossal cyst was reported in the left submandibular region in a 14-year-old girl, above the level of hyoid bone; ultrasound examination favored a cystic lesion which moved in a vertical fashion on swallowing whereas fine needle aspiration cytology report was suggestive of simple cystic lesion of thyroglossal cyst. No lymphoid or malignant cells were present. The cyst was excised completely by surgical procedure under general anesthesia. Histopathological analysis revealed thyroglossal cyst showing columnar and flattened epithelium of cyst with focal aggregate of chronic inflammatory cells supported by fibrocollagenous cyst wall. The clinical, ultrasound, and histopathological findings suggested that the lesion was an infected thyroglossal cyst. There was no evidence of recurrence 6 months after surgery.

    Introduction Rosai–Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a rare histiocytic disorder of unclear etiology. Lymphadenopathy commonly affects the lymph nodes of the neck and the head, but extranodal involvement has been observed too. Presentation of case We describe an unusual case of RDD with involvement of the gallbladder, liver and cystic lymph node, clinically manifested as an exacerbated cholecystitis. The patient underwent a cholecystectomy with atypical liver resection because the finding was macroscopically suspected of gallbladder cancer. The diagnosis of RDD was confirmed by immunohistochemical study. Discussion Histological features of RDD include histiocytic proliferation, emperipolesis and positive immunostaining for S-100 protein and typically negative for CD1a. Gastrointestinal localization of RDD, especially in the liver and pancreas, is extremely rare. Typically, the liver is affected as a part of systematic spread of RDD. We have not found reports for involvement of the gallbladder. Conclusion The presented case is valuable due to its rarity and difficulty in differential diagnosis. PMID:26073916

    2015-01-01

    Full Text Available Noninvasive prenatal testing (NIPT validation studies show high sensitivity and specificity for detection of trisomies 13, 18, and 21. False negative cases have rarely been reported. We describe a false negative case of trisomy 13 and another of trisomy 18 in which NIPT was commercially marketed directly to the clinician. Both cases came to our attention because a fetal anatomy scan at 20 weeks of gestation revealed multiple anomalies. Karyotyping of cultured amniocytes showed nonmosaic trisomies 13 and 18, respectively. Cytogenetic investigation of cytotrophoblast cells from multiple placental biopsies showed a low proportion of nontrisomic cells in each case, but this was considered too small for explaining the false negative NIPT result. The discordant results also could not be explained by early gestational age, elevated maternal weight, a vanishing twin, or suboptimal storage or transport of samples. The root cause of the discrepancies could, therefore, not be identified. The couples involved experienced difficulties in accepting the unexpected and late-adverse outcome of their pregnancy. We recommend that all parties involved in caring for couples who choose NIPT should collaborate to clarify false negative results in order to unravel possible biological causes and to improve the process of patient care from initial counseling to communication of the result.

    Case study as a research design means investigating a single or multiple instance(s) or setting(s) (i.e. a case) and its entire context to explain a phenomenon and its processes. This is achieved through detailed understanding, usually comprised of multiple sources of information. In this way, case...... studies attempt to provide as a complete an understanding of a (complex) phenomenon as possible. Within the AEGIS project, survey and case study research are complementary. They are complementary in the sense that the former can provide more generalizable evidence on a phenomenon in terms of cross......-sectional data, while the latter can provide more in-depth (qualitative) understanding on specific issues. In systematically examining the case studies, however, this report goes beyond a typical single case study. Here we provide a synthesis of 86 case studies.

    Bond, G G

    1993-01-01

    The need to notify individuals of a possible health risk from their past exposure to potentially hazardous agents frequently extends beyond workers to include community groups. The issues to consider in community notification are frequently similar to those that are important for worker notification but may include some that are unique. This case study traces the evolution of one company's strategy for communicating with the public about possible dioxin contamination associated with its operations. Early communications tended to emphasize the technical aspects of the issues in the fashion of scientists talking to other scientists. This was interpreted by some to be symptomatic of an arrogant and uncaring attitude. Beginning in the early 1980s, the company's management recognized the need to reach out to a variety of audiences on multiple levels, and shifted to a more comprehensive communications strategy. A similar shift is now occurring throughout the chemical manufacturing industry as top managers realize that, if they expect to continue to operate, they must become more accountable and responsive to the public.

    Full Text Available The ultimate objective of manufacturing industries is to increase productivity with high quality. At present, many manufacturing companies are facing problems such as high quality rejection, high inventories, high lead time, high costs of production, and inability to cope with customer orders. By implementing and practicing the lean production system many problems can be solved without employing high-tech and high-touch approaches but by involving people on the shop floor in Kaizen activities. Kaizen is one of the powerful tools of lean manufacturing. Kaizen refers to continuous improvement in performance, cost and quality. Kaizen ensures that manufacturing processes become leaner and fitter, but eliminate waste (problem where value is added. The main objective of this paper is to provide a background on kaizen, present an overview of kaizen concepts that are used to transform a company into a high performing lean enterprise. A case study of implementation of Kaizen‟s has been discussed.

    Full Text Available Evidence suggests that interaction between key genes mediating signaling and transcriptional networks involving effector T-cell responses may influence an individual's susceptibility to develop allergic rhinitis(AR.The aim of this study was todetermine whether specific interactions between key genes involved in effector T-cell pathways are associated with an individual's susceptibility to develop AR in Han Chinese subjects.A cohort of 489 patients with AR and 421 healthy controls was enrolled from the Han Chinese population in Beijing, China. AR was established by questionnaire and clinical examination, and peripheral blood was drawn from all subjects for DNA extraction. A total of 96 single nucleotide polymorphisms (SNPs in 26 reprehensive candidate genes involved in T helper 1 (Th1, Th2, Th17, Th9 and T regulatory cell pathways were selected from the International Haplotype Mappingdatabase for Han Chinese in Beijing (CHB population, and IlluminaGoldenGate assay was conducted for SNP genotyping. The PLINK software package was used to perform statistical analyses.Simple SNP-phenotype association analysis using logistic regression showed SNP rs8193036 in IL17A gene, rs2569254 in IL-12 and rs1898413 in RORα weresignificantlyassociatedwith AR.Simple SNP-phenotype association analysis with genetic models demonstrated thatrs2569254 in IL-12, rs1031508 in STAT4, and rs3741809 in IL-26 were likely to be recessive, rs8193036 in IL17A allelic, rs897200in STAT4 genotypic, and rs1898413 in RORα dominant. Epistasis analyses exhibited that 83 SNPs in 23 genes were significantly interactive; of which 59 interactions/SNP pairs demonstrated OR values higher than 2 or lower than 0.5, and 12 interactions/SNP pairs OR values higher than 4 or lower than 0.25. STAT3, RORα and IL-26, involved in Th17 pathway,were the mostfrequentlyinteractive genes.This study suggests that interactions between several SNPs in key genes involved in effector T-cell pathways are

    The multifamily case studies that are the subject of this report were conducted to provide a better understanding of the approach taken by program operators in weatherizing large buildings. Because of significant variations in building construction and energy systems across the country, five states were selected based on their high level of multifamily weatherization. This report summarizes findings from case studies conducted by multifamily weatherization operations in five cities. The case studies were conducted between January and November 1994. Each of the case studies involved extensive interviews with the staff of weatherization subgrantees conducting multifamily weatherization, the inspection of 4 to 12 buildings weatherized between 1991 and 1993, and the analysis of savings and costs. The case studies focused on innovative techniques which appear to work well.

    2012-01-01

    Wegener Granulomatosis (WG) is a multisystem autoimmune disorder characterized by necrotizing granulomatous vasculitis that most commonly involves the upper respiratory tract, lungs, and kidneys. The involvement of the central nervous system (CNS) is infrequent and can cause stroke, cranial nerve abnormalities, cerebrovascular events, seizures, and meningeal involvement. Meningeal involvement is rare and may occur due to local vasculitis, directly spread from adjacent disease in the skull base, paranasal or orbital region. We describe the case of a 20-year-old Caucasian man who was diagnosed with sinonasal WG with frontal focal meningeal involvement. A literature review on diagnosis and treatment of meningeal involvement in course of WG was carried out. The importance of an early diagnosis and treatment of localized WG has been emphasized, in order to avoid the progression to a severe form of disease, especially in younger patients and in paucisymptomatic cases.

  5. Disrupt, Support and Document: The Role of Social Media in International Parental Child Abduction Cases Involving Japan

    Directory of Open Access Journals (Sweden)

    Geraldine Carney

    2016-07-01

    Full Text Available In this article, I examine the use of social media by parents involved in cases of international parental abduction to and from Japan, with a focus on cases of abduction to Japan. I argue that the use of social media in these cases is a symptom of and a counter to a legal system which has been outpaced by changes in society, particularly the creation and dissolution of international families. This article discusses a number of case studies of social media usage and locates these in the context of the contemporary Japanese legal system. While not ignoring the nefarious potential of social media usage, I come to a positive assessment of its use in cases of international parental child abduction involving Japan. I also question how its utility will change over time, depending on the legal system’s ability to adapt to societal changes and expectations.

    Full Text Available According to Sir William Osler, Mouth is the mirror of the body which reflects systemic -diseases. The oral mucosa may be affected by a variety of mucocutaneous diseases and oral lesions may occur first or very early in several mucocutaneous disorders. The erosive gingival lesions associated with vesiculobullous diseases such as lichen planus, cicatricial pemphigoid, and pemphigus vulgaris have been collectively referred to as "Desquamative gingivitis" (DG. Gingival desquamation is a clinical sign in which the gingiva appears reddish, painful, glazed and friable with destruction of the epithelium. This gingival desquamation is due to various disease processes in gingiva. The disease process may be a localized disease of gingiva or a systemic disease which manifests in the gingiva. It is important to be aware of this rare clinical entity so as to distinguish DG from plaque induced gingivitis which is an extremely common condition, easily recognized and treated daily by the dental surgeon. Accurate diagnosis and effective treatment of these lesions may greatly diminish or reverse disease progression. Here by, we present a case of mucous membrane pemphigoid presenting as gingival desquamation in a 45 year old female. Our patient presented with generalized erythematous gingiva and gingival desquamation involving the free, attached and marginal gingiva of left maxillary and mandibular dentition. However, other mucosal and skin involvement was not appreciated in the present case. Thorough history, clinical examination, histopathology and immunofluorescence studies helped us to arrive at the diagnosis of this rare sub-epithelial blistering disorder.

    Full Text Available Abstract Background Carcinoma of the gallbladder (GBC clinically mimics benign gallbladder diseases and often escapes detection until advanced stage. Despite the frequency of cholecystectomy, diagnosis of GBC remains problematic in many situations. We sought to identify pathologic features that contribute to the difficulty in recognition of GBC. Methods We identified 23 patients (ranged from 45 to 86 years, male to female ratio 1:4.5 with carcinoma involving the gallbladder referred to an academic medical center over a period of 10 years for study. This includes 10 cases of primary GBC, 6 cases of metastatic tumor to gallbladder, 6 cases of directly invasive adenocarcinoma arising elsewhere in the biliary tree, and one case of unidentified origin adenocarcinoma. Primary tumors include adenocarcinoma not otherwise specified (NOS in 6 cases, papillary adenocarcinoma in 2 cases, and single cases of undifferentiated carcinoma and combined adenocarcinoma and neuroendocrine carcinoma (NEC. Metastatic tumors to gallbladder were from a wide range of primary sites, predominantly the gastrointestinal tract. Results These cases illustrate seven potential pitfalls which can be encountered. These include: 1 mistakenly making a diagnosis of adenocarcinoma of gallbladder when only benign lesions such as deeply penetrating Rokitansky-Aschoff sinuses are present (overdiagnosis, 2 misdiagnosing well-differentiated invasive carcinoma with minimal disease as benign disease (underdiagnosis, 3 differentiating between primary NEC of gallbladder and metastasis, 4 confusing primary mucinous adenocarcinoma of gallbladder with pseudomyxoma peritonei from a low grade appendiceal neoplasm disseminated to gallbladder, 5 confusing gangrenous necrosis related to cholecystitis with geographic tumoral necrosis, 6 undersampling early, grossly occult disease, and 7 misinterpreting extracellular mucin pools. Conclusions Clinical history and a high index of suspicion are

    Najman, A; Gorin, N C; Barranger, C; Duhamel, G

    1977-11-12

    Gastro-intestinal involvement is a distinctive feature of non-Hodgkin's lymphomas. 31 cases are reported among 200 cases on NHL observed between 1960 and 1976. Multiple involvement appeared in 61%; a diffuse histological pattern is frequent (67%). The relapse of primary isolated gastro-intestinal localization (always) affected extra-digestive tissues (nodes, cavum). Chemotherapy is the mainstay of treatment COP, COAP and MOCA. Surgery is associated in localized involvement or in case of obstruction. High energy radiation therapy is indicated only in lymphosarcomas: -- to residual tumor after chemotherapy--in localized involvement diffuse on all the abdomen at 25 grays after surgery and a brief course of chemotherapy versus surgery and long course of chemotherapy alone.

    Mabray, Marc C.; Glastonbury, Christine M.; Mamlouk, Mark D.; Punch, Gregory E.; Solomon, David A.; Cha, Soonmee

    2017-01-01

    Malignant gliomas are characterized by infiltrative growth of tumor cells, including along white matter tracts. This may result in clinical cranial neuropathy due to direct involvement of a cranial nerve rather than by leptomeningeal spread along cranial nerves. Gliomas directly involving cranial nerves III-XII are rare with only eleven cases reported in the literature prior to 2014, including eight with imaging. We present eight additional cases demonstrating direct infiltration of a cranial nerve by glioma. Asymmetric cisternal nerve expansion as compared to the contralateral nerve was noted with a mean length of involvement of 9.4 mm. Based on our case series, the key imaging feature to recognize direct cranial nerve involvement by a glioma is the detection of an intra-axial mass in the pons or midbrain that is directly associated with expansion, signal abnormality, and/or enhancement of the adjacent cranial nerve(s).

    2015-02-01

    Mosaicism for an autosomal structural rearrangement that does not involve ring or marker chromosomes is rare. The mechanisms responsible for genome instability have not always been explained. Several studies have shown that interstitial telomeric sequences (ITSs), involved in some mosaic constitutional anomalies, are potent sources of genomic instability. Here we describe two cases of mosaicism for uncommon constitutional autosomal rearrangements, involving ITSs, identified by karyotyping and characterized by FISH and SNP-array analysis. The first patient, a boy with global developmental delay, had a rare type of pure distal 1q inverted duplication (1q32-qter), attached to the end of the short arm of the same chromosome 1, in approximately 35% of his cells. The second patient, a phenotypically normal man, was diagnosed as having mosaic for a balanced non-reciprocal translocation of the distal segment of 7q (7q33qter), onto the terminal region of the short arm of a whole chromosome 12, in approximately 80% of his cells. The remaining 20% of the cells showed an unbalanced state of the translocation, with only the der(7) chromosome. He was ascertained through his malformed fetus carrying a non-mosaic partial monosomy 7q, identified at prenatal diagnosis. We show that pan-telomeric and subtelomeric sequences were observed at the interstitial junction point of the inv dup(1q) and of the der(12)t(7;12), respectively. The present cases and review of the literature suggest that the presence of ITSs at internal sites of the chromosomes may explain mechanisms of the patients's mosaic structural rearrangements.

    Case studies may have different research goals. One such goal is the testing of small-scale and middle-range theories. Theory testing refers to the critical examination, observation, and evaluation of the 'why' and 'how' of a specified phenomenon in a particular setting. In this paper, we focus...... on the strengths of theory-testing case studies. We specify research paths associated with theory testing in case studies and present a coherent argument for the logic of theoretical development and refinement using case studies. We emphasize different uses of rival explanations and their implications for research...... design. Finally, we discuss the epistemological logic, i.e., the value to larger research programmes, of such studies and, following Lakatos, conclude that the value of theory-testing case studies lies beyond naïve falsification and in their contribution to developing research programmes in a progressive...

    2012-06-01

    Full Text Available Purpose: In a multitude of studies, it is verified that the generation of positive attitudes for employees such as job satisfaction or job involvement, have a positive influence on productivity levels of companies. The current investigation focus on the identification of employee-profile -who is emotionally involved with their work activity- through the use of a set of individual, job related and attitudinal factors.Design/methodology: A review of the literature about the main factors that affect the job involvement particularly on its emotional dimension has been completed. For its measurement at the empirical level, various items related to psychological well being of employees included in the IV European Working Conditions Survey-2010 are used. Moreover, those items are identified in Job Involvement Questionnaire (Lodahl & Kejner, 1965. Since then, an empirical and multidimensional study is carried out by applying a logistic regression model on the sample of 11,149 employees obtained with European survey cited previously.Findings: The logistic regression model identifies the factors, which are directly related to emotional involvement at the workplace. Ultimately, is raised a definitive model that define the European employee-profile -who is emotionally involved at the workplace-: a rather aged person who has been working at his/her present place of employment for several years in a medium-sized company where possibly there exist a good working relationship between workers and their superiors –social support-. These employees are “white-collar” workers, have career advancement opportunities in the organizational hierarchy. They perform variety, flexible and complex tasks, which leads to satisfaction in terms of pay and working conditions.Research limitations/implications: Emotional involvement has been measured through self-awareness and, therefore, the corresponding bias in the key variable must be assumed. In addition, the casual

    2008-05-01

    Full Text Available Abstract Introduction Angio-osteohypotrophic syndrome is also known as Servelle-Martorell angiodysplasia. It is characterized by venous or, rarely, arterial malformations, which may result in limb hypertrophy and bony hypoplasia. Extensive involvement of the upper limb is a rare feature of Servelle-Martorell syndrome. Cases with minimal upper limb involvement have been described in the literature. Case presentation A young man presented with multiple separate swollen areas over the right upper limb and functional difficulty since birth. The arm muscles and muscles of the limb girdle were atrophic. The forearm and hand bones were hypoplastic and tender. Conclusion We report a case of Servelle-Martorell syndrome with extensive involvement of the entire upper limb and periscapular region. Servelle-Martorell syndrome is highlighted as one of the causes of angiodysplastic limb hypertrophy.

    Everyone in science should have ethics education training. I have seen graduate students taken advantage of by their mentors. Many of us have seen misconduct...but what should we do about it? Young scientists are often unaware of the rules in science and make mistakes because of their ignorance of the rules in that particular field of study. Then there are an increasing number of cases in the news of overt cases of misrepresentation in science. All are welcome to attend this discussion of case studies. A case study on topics such as: how to treat data properly, how our values in science affect our work, who gets authorship on scientific papers, who is first author on a paper, what you should do if you uncover misconduct or plagiarism in your university, and we will discuss the scientist's role in society.

    2006-03-01

    We report a case of a 71-year-old man infected at a nursing home who developed a bullous pemphigoid-like eruption with nail involvement. He was diagnosed by his family doctor as suffering from eczema and was treated with topical corticosteroids, then blisters started appearing. He was next diagnosed as suffering from bullous pemphigoid and treated with oral prednisolone, which worsened his condition. He was finally diagnosed as having crusted scabies with bullous pemphigoid-like eruptions and nail involvement at our clinic. He was then prescribed oral ivermectin (two doses of 12 mg ivermectin with a 1-week interval) and topical lindane (1%gamma-BHC in petrolatum) for scabies with 5% salicylic acid in plastibase as an additional treatment for the crusted lesions on his soles. He showed remarkable improvement in 2 weeks, and his nails showed complete recovery after 7 weeks of occlusive dressing treatment with 1%gamma-BHC. One and a half years later, the patient showed no sign of a recurrence of scabies. The histology of a blister taken from this patient was similar to that of bullous pemphigoid. Direct immunofluorescence showed immunoglobulin (Ig)G and C3 deposition at the dermoepidermal junction similar to that of bullous pemphigoid, but indirect immunofluorescence was negative. The bullous symptoms of this patient were considered to be due to the scabies, because the patient recovered completely after receiving treatment for scabies. Indirect immunofluorescent study is important to distinguish between scabies with blister formation and true bullous pemphigoid.

    A 70-year-old woman presented with follicular lymphoma involving the stomach, duodenum, jejunum, bone, and lymph nodes. Esophagogastroduodenoscopy revealed multiple depressed lesions in the stomach. Examination with magnifying endoscopy showed branched abnormal vessels along with gastric pits, which were irregularly shaped but were preserved. The second case was a 45-year-old man diagnosed with stage II1 follicular lymphoma with duodenal, ileal, and colorectal involvement, as well as lymphadenopathy of the mesenteric lymph nodes. Esophagogastroduodenoscopy performed six years after the diagnosis revealed multiple erosions in the gastric body and angle. Magnifying endoscopic observation with narrow-band imaging showed that the gastric pits were only partially preserved and were destroyed in most of the stomach. Branched abnormal vessels were also seen. Pathological features were consistent with follicular lymphoma in both cases. The structural differences reported between the two cases appear to reflect distinct pathologies. Disappearance of gastric pits in the latter case seems to result from loss of epithelial cells, probably due to chronic inflammation. In both cases, branched abnormal vasculature was observed. These two cases suggest that magnified observations of abnormal branched microvasculature may facilitate endoscopic detection and recognition of the extent of gastric involvement in patients with follicular lymphoma.

    Renal dysfunction is increasingly recognized as a potential clinical feature of mitochondrial cytopathies such as mitochondrial encephalomyopathy, lacticacidosis and stroke-like episodes (MELAS) syndrome. Five cases of MELAS syndrome with renal involvement from 4 unrelated families are presented in this case series. Three of the 5 patients had a history of maternally-inherited diabetes and/or deafness. Focal and segmental glomerulosclerosis and arteriolar hyaline thickening were the most striking findings on renal biopsy. In addition to clinical presentation with the typical symptoms of MELAS syndrome, genetic testing in these patients identified the A3243G point mutation in the tRNALeu gene of the mitochondrial DNA (mtDNA). The diagnosis of MELAS syndrome was thus considered to be unequivocal. The incidence of kidney disease in MELAS syndrome may be underestimated although a study is required to investigate this hypothesis. As the A3243G mtDNA mutation leads to a progressive adult-onset form of focal segmental glomerulosclerosis (FSGS), screening for the MELAS A3243G mtDNA mutation should therefore be performed especially in patients with maternally-inherited diabetes or hearing loss presenting with FSGS.

    Objective To investigate the possibility and surgical procedures for huge liver cancer involving the second porta hepatis.Methods 55 cases of huge liver cancer, with the diameter of 8-28 cm(mean 12.7 cm) were studied. Right subcostal or “rooftop” incision was made, the liver ligments were divided, good exposure of the tumor and access to retrohepatic inferior vena cava were achieved.Hepatectomies were completed under intermittent interruption of first porta hepatis. Occluding tape around vena cava was applied before liver resection if necessary.Results All tumors were successfully resected without death during operation.The longest survival time was now 4 years in one case. The 1-4 year postoperative survival rates were 63%,50%,50% and 30% respectively.Conclusion Young patients with solitary large liver tumor, which grows slowly over a long period on basis of non-cirrhotic or mild cirrhotic liver, should undergo an exploration in an attempt of resection irrespective of the image contraindication, provided that there is no extra-hepatic metastasis.

    Three hundred leprosy patients were recruited to study the pattern and frequency of nail changes. Nail changes, like longitudinal ridging in finger nails, transverse striations involving both finger and toe nails etc. which occurred with similar frequency in the PB and MB patients in comparison with the control group, were excluded from the analysis. Out of a total number of 150 PB patients, 84 (56%) showed nail changes. Fifty-eight (38.6%) patients showed changes in the finger nails, with an average of 3.2 involved nails per patient. Fifty-three (35.3%) patients showed changes in the toe nails, with an average of 3.0 nails per patient. The most common change observed was longitudinal melanonychia (32.4%) in the finger nails and longitudinal ridging (46.3%) in the toe nails.In comparison, 131/150 (87.3%) MB patients showed nail changes. Finger nail changes were seen in 102 (68%) patients with an average of 5.5 nails affected per patient. Changes in toe nails were seen in 116 (77.3%) patients, with an average of 6.0 nails involved per patient. The most common nail change observed was longitudinal melanonychia in 89/523, (17%) of the total involved finger nails and subungual hyperkeratosis in 164/702, (23.4%) of the total toe nails involvement. Out of a total of 32 colony patients, 31 (96.9%) showed nail changes both in finger and toe nails with an average of 7.9 and 8.4 affected nails per patient, respectively. The most common nail change observed was rudimentary nail(s) on fingers (29%) and toes (21.1%). Among MB patients, a significantly higher number had finger nail involvement in LL group. The frequency of nail involvement for both fingers and toes was significantly greater in LL as compared to BL group of patients. The frequency of nail involvement was significantly more in patients having disease for more than 5 years and in those having trophic changes secondary to loss of sensations and impaired circulation.

    1990-04-01

    One thousand, four hundred and forty-six patients with carcinoma of the breast treated with Halsted mastectomy (167), Patey mastectomy (732), and conservative surgery with axillary dissection, either at the same time (340), or separately (207), were evaluated with regard to the number and distribution of axillary lymph nodes. A total of 29,378 were removed and examined, on average 20.3 per patient. The average number of nodes was 13.5 at the first level, 4.5 at the second and 2.3 at the third. The same number of nodes were removed in patients treated with extensive surgery, such as Halsted mastectomy and limited surgery such as lumpectomy and in independent axillary dissection. In 839 cases metastases were found in the axilla. The average number of involved nodes was 6.4. Out of 839 patients, the first level was the site of metastases in 828, the second level in 364 and the third in 187. When a single lymph node was involved, it was nearly always at the first level. In only 11 cases, were the second and/or third levels invaded without metastases at the first level. Therefore, the percentage of cases with skipping metastases was very low (1.3%). It appears from the present data that the spread of breast cancer to the axilla follows a regular pattern; the first level is invaded first, whilst in most cases, the second and third levels are involved only when the first is substantially affected.

    2010-10-01

    Full Text Available Abstract Background Penetrating injuries of the abdomen and spinal canal that involve organic material of animal origin are extremely rare and derive from domestic and wild animal attacks or fish attacks. Case presentation In this case report we present the unique, as far as the literature is concerned, unprovoked woman's injury to the abdomen by a swordfish. There are only four cases of swordfish attacks on humans in the literature - one resulted to thoracic trauma, two to head trauma and one to knee trauma, one of which was fatal - none of which were unprovoked. Three victims were professional or amateur fishermen whereas in the last reported case the victim was a bather as in our case. Our case is the only case where organic debris of animal's origin remained in the spinal canal after penetrating trauma. Conclusions Although much has been written about the management of penetrating abdominal and spinal cord trauma, controversy remains about the optimal management. Moreover, there is little experience in the management of patients with such spinal injuries, due to the fact that such cases are extremely rare. In this report we focus on the patient's treatment with regard to abdominal and spinal trauma and present a review of the literature.

    McPhillips, A; Wolford, L M; Rodrigues, D B

    2010-12-01

    Synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) syndrome is a rare group of sterile, inflammatory osteoarticular disorders classically associated with skin manifestations. The etiology is unknown but probably involves genetic, infectious, and immunological components. The characteristic feature of the disease is found in the bone lesions, which typically involve the anterior chest wall and axial skeleton. In the literature review, six case reports discussed involvement of the TMJ. Treatment of SAPHO is geared toward symptom management as there is no cure. Surgery for mandibular lesions is usually a last resort as results are reported to be temporary with symptoms recurring within a year. Surgery appears to be performed early after diagnosis of TMJ related pathology; probably because lesions affecting the TMJ involve some limitation in mouth opening with varying degrees of ankylosis. The authors provide a literature review and describe a case of SAPHO syndrome with ankylosis of the left TMJ. The patient was treated with joint reconstruction using a patient-fitted total joint prosthesis (TMJ Concepts Inc., Ventura CA) in single stage surgery. This paper is the first to report maxillary involvement in SAPHO syndrome.

    Necrotizing fasciitis represents a group of highly lethal infections characterized by rapidly progressing inflammation and necrosis. The aim of the study was to analyze the clinical profile, microbial flora, and predisposing risk factors in patients with necrotizing fasciitis. Lastly, we aimed to formulate a protocol for management of necrotizing fasciitis. Forty-eight cases of necrotizing fasciitis patients who reported to our hospital between April 2007 and September 2009 were included in the study. The commonest predisposing factors were age greater than 50 years (58 % cases) and diabetes mellitus (52 % cases). The commonest site involved was extremity (70.8 %). Majority of infections were polymicrobial (87.5 %). Repeated aggressive debridement was the commonest surgical procedure performed. Early and aggressive surgical debridement, often in multiple sittings, supplemented by appropriate antibiotics and supportive therapy, forms the key to a successful outcome in necrotizing fasciitis.

    选择上海社保基金案为研究对象,根据2004~2008年年末注册地为上海的上市公司的年报、临时公告和纸质新闻媒体报道资料,手工搜集了关键高管(董事长与总经理)的政治联系数据和公司涉案与否的数据,实证研究了涉案行为与政治联系之间的关系,以及涉案行为在上海社保基金案之前、期间和之后对公司审计意见的影响.研究结果表明,政治联系的上市公司显著地更可能涉案,且在上海社保基金案曝光的2006年,涉案公司被出具非标审计意见的概率显著更高;但若以2006年为基准,在上海社保基金案之前的2004~2005年、之后的2007~2008年,涉案公司被出具非标审计意见的概率显著更低.%This paper focuses on the legal case of Shanghai social security fund. Firstly, based on the annual reports and temporary announcements of public listed companies registered in Shanghai from 2004 to 2008, as well as some reports from news media, this paper manually collects political connections data of key top managers of sample companies and the involved data. Secondly, it empirically studies the relation between political connections and involved behaviors, and the impact of involved behaviors on audit opinions before, during and after the case. The results show that among sample companies registered in Shanghai, the ones with political cònnections have a significantly higher possibility to be involved in the case than others. In 2006 when the legal case was exposed, involved companies have a higher possibility of receiving unqualifiedaudit opinions; however, from the year 2004 through 2005 and from the year 2007 through 2008, the possibility of involved companies to receive unqualified auditor opinions from auditors was lower.

    Immunoglobulin G4 (IgG4)-related disease is a well-known disorder characterized by an inflammatory reaction with an increase in the number of IgG4-positive plasma cells associated with sclerosis. IgG4-related disease often affects the dura mater with a pattern of diffuse thickening when the central nervous system is involved. However, some nodular dural thickening requires discrimination from tumors because of obviously different treatment options. We report of a case of IgG4-related disease with tumefactive dural involvement.

    Sweet syndrome (acute febrile neutrophilic dermatosis) is a dermatologic disorder with accompanying features of systemic inflammation. It is commonly associated with conjunctivitis, but a variety of types of ocular inflammation have been reported. The ocular manifestations of Sweet syndrome include periorbital and orbital inflammation, dacryoadenitis, conjunctivitis, episcleritis, scleritis, limbal nodules, peripheral ulcerative keratitis, iritis, glaucoma, and choroiditis. The ocular inflammation appears concurrently with skin lesions. An overview of Sweet syndrome is presented with a review of cases in the literature describing ocular involvement. We report two additional cases of ocular involvement, one with conjunctivitis and a second with iritis, peripheral ulcerative keratitis, and episcleritis. Of the 20 cases, half were bilateral. Thirteen cases occurred in the setting of classical or idiopathic Sweet syndrome and seven in association with malignancy. Biopsies of ocular tissue were infrequent, but, in the seven cases where ocular tissue was analyzed, the histopathology was similar to that of the cutaneous lesions. The ocular complications of Sweet syndrome resolved with systemic administration of corticosteroid or cyclosporine. Topical ocular steroid treatment was frequently used in conjunction with oral steroid but may not have been valuable.

    Pituitary metastasis is an uncommon first presentation of systemic malignancy. The most common presenting symptom of pituitary metastasis is diabetes insipidus reflecting involvement of the stalk and/or posterior pituitary. We herein present a unique case of the coexistence of both a functioning pituitary adenoma (prolactinoma) and pituitary metastasis of advanced colorectal cancer with pituitary apoplexy as the first manifestation of underlying malignancy. The present case emphasizes the need to consider pituitary metastasis as a differential diagnosis in patients presenting with pituitary lesions and be aware that tumor-to-tumor metastasis can occur unexpectedly in those with pituitary metastases.

    2012-02-15

    This is a case report of Churg-Strauss Syndrome (CSS) associated with cardiac involvement which is demonstrated in chest CT and cardiac MRI (CMR) without specific cardiac symptoms. A 32-year-old woman had a 3-year history of bronchial asthma, chronic sinusitis, and otitis media. The patient had various typical findings of CSS. The patient had no specific cardiac symptoms or signs such as chest pain, palpitations, syncope, or murmur, but she had diffuse low attenuation lesions in the inner wall of the left ventricle (LV) in contrast-enhanced CT. This corresponded to the area of subendocardial hyperenhancement in delayed contrast-enhanced CMR images. She was treated with steroids for 2 months. Follow-up delayed contrast-enhanced CMR of the LV showed a decrease in the size of the subendocardial enhancement area, and she had no symptoms. Therefore, the radiologist and clinician both should pay careful attention to observe possible cardiac involvement in case of CSS.

    2016-01-01

    Squamous cell carcinoma (SCC) is the second-most common malignant cutaneous cancer, with 60% occurring in the head and neck region. Metastases are uncommon and imply a more conservative prognosis. This report describes a case of parotid-invasive, facial squamous cell carcinoma, highlighting the importance of its prognostic and therapeutic management. The patient is an 81-year-old female, exhibiting extensive tumoral lesions in the pre-auricular region, affecting the parotid parenchyma and implying the metastatic involvement of the intra-parotid lymph node. Parotid involvement caused by SCC in specificity tumors is discussed herein. Parotid invasion is currently recognized as an isolated variable. It affects survival rates and determines certain changes in case management, such as the broadening of resection areas and adjuvant radiotherapy. PMID:27438204

  3. Attitudinal and individual differences influence perceptions of mock child sexual assault cases involving gay defendants.

    Wiley, Tisha R A; Bottoms, Bette L

    2013-01-01

    Many people hold negative attitudes and stereotypes about gay men, including the stereotype that gay men are likely to be child molesters. This article explored the implications of this stereotype for judgments made in a hypothetical legal case involving child sexual abuse accusations against a male teacher by either a male or female victim. Mock jurors who held the most anti-gay attitudes and those who endorsed the stereotype of gay men as child molesters made the most pro-prosecution judgments in scenarios involving gay defendants. A new scale (the Stereotypes about Gays and Child Abuse scale) was developed to assess the extent to which participants endorsed the stereotype of gay men as being likely to sexually abuse children. This scale was a stronger predictor of case judgments than existing, more general scales measuring biases against homosexuality.

    Marchiafava-Bignami disease (MBD) is a rare toxic disorder strongly associated with chronic alcoholism. It is characterized by progressive demyelination and necrosis of the corpus callosum. The process may extend to neighboring white matter and subcortical regions. We report a case of MBD in which fluid-attenuated inversion recovery and diffusion-weighted imaging revealed symmetrical hyperintense lesions with diffuse involvement of the corpus callosum, white matter, corticospinal tract, internal capsule, and middle cerebellar peduncle.

    Peripheral T-cell lymphoma is a rare type of lymphoma that's derived from postthymic lymphoid T cells. Pulmonary involvement of peripheral T-cell lymphoma of the unspecified type is very rare and the imaging findings of this illness have rarely been reported. We present here a case of peripheral T-cell lymphoma of the unspecified type with a cavitary lesion in the lung parenchyma, and we pathologically confirmed this illness by performing video-assisted thoracoscopic surgery.

    Castleman's disease is an uncommon lymphoproliferative disorder characterized by lymph node enlargement, hyperplasia of lymphoid follicles surrounded by mature lymphocytes, and capillary proliferation with endothelial hyperplasia. Although intracranial location is very uncommon, it should be considered in the differential diagnosis of meningeal tumors. We describe a new case appearing as two solid extraaxial masses simulating meningiomas. This multifocal meningeal involvement can be considered as an exceptional form of presentation of intracranial Castleman's disease.

    Cervical spondylolysis is a rare condition, and less than 100 cases have been reported in the world literature. Cervical spondylolysis is defined as a well corticated defect in the posterior element of a cervical vertebra. Although the etiology of cervical spondylolysis is unknown, its association with dysplastic changes and spina bifida occulta suggest that the lesion is congenital. Here, we describe the radiographs and CT images of cervical spondylolysis involving four levels in a 9 year old boy.

    Full Text Available The purpose of this study is to investigate family involvement activities at preschool educational institutions in province of Denizli. 25 female teachers working at preschool educational institutions under Ministry of National Education in city centre of Denizli were included in the study. The results revealed that while a great majority of 32 family involvement activities included in the questionnaire (parents' corner, posters, education board, communication board, brochures, booklets, periodicals-newspapers, newsletters, correspondences, photographs, phone/ internet calls, video/tape records, conferences, home visits, article box, request box, parents' libraries, family involvement to non-classroom activities, diaries, family involvement into management and decision-making process, group meeting weren’t performed, 11 activities were implemented. While 4 of 11 activities were performed by all teachers, there were teachers who didn't perform 7 family involvement activities (parents' meetings, individual interview, development reports, collective files, involvement to classroom activities, invitation of parents to the school in special occasions, activities held at home. Considering the reasons why twenty two family involvement activities were not performed; lack of space, time and possibilities was the most frequent reason. Home visits took place on the top among family involvement activities the teachers had difficulties at most. The individual interviews were among activities conducted by the teachers in the easiest/ comfortable way.

    [Purpose] Systemic lupus erythematosus (SLE) is a chronic, immune-mediated disease, affecting 0.1% of the general population. To date, few studies have investigated the efficacy of physical therapy for SLE patients with CNS involvement. The aim of this study was to report whether the combined use of corticosteroids and physical therapy, consisting of reflex inhibition and functional training, was beneficial to functional recovery. [Subjects and Methods] A 22-year-old male SLE patient with CNS involvement requested physical therapy due to strong spasticity of the trunk and limbs in a bedridden state. Corticosteroid intervention and physical therapy were undertaken for 16 days. [Result] After 16 days of the interventions, the patient demonstrated stabilized and alleviated neurological symptoms and an improved functional level. [Conclusion] The present case indicates that physical therapy combined with corticosteroids might be a possible treatment and rehabilitation method to effectively recover motor function for SLE patients who have strong spasticity due to CNS involvement.

    Full Text Available Brucellosis is a zoonosis that can affect many organs or systems. Musculoskeletal system is the most commonly affected site in brucellosis and the frequency of musculoskeletal system involvement varies between 2% and 53%. Multifocal spinal involvement is rare. Here, it was aimed to present our case with brucellar spondylodiscitis involving the thoracic and lumbar regions simultaneously. MRI is a useful imaging method in the diagnosis of multifocal spinal infection caused by brucellosis. Especially in endemic regions, at least two serological tests should be used in the diagnosis of brucellosis. Brucellosis should be absolutely kept in mind for the differential diagnosis of the lderly patients with complaint of longstanding thoracic and back pain in the regions where brucellosis is endemic.

    Full Text Available Wegener′s granulomatosis (WG is a necrotizing granulomatous vasculitis invol-ving the nose, paranasal sinuses, lungs, and kidneys. Ocular involvement can occur in about 50% of cases. There are very few reports of WG with orbital inflammation and exorbitism. We report a case of a female patient who presented with exorbitism related to orbital inflammation secondary to WG, with renal involvement. A 29-year-old woman with a previous history of recurrent pan-sinusitis presented with bilateral exophthalmos and renal failure with rapidly progressive glo-merulonephritis. Computed tomography showed extensive bilateral soft tissue in the retro-orbital area. Immunologic tests showed the presence of type-C anti-neutrophil cytoplasmic antibodies and renal biopsy revealed pauci immune crescentic glomerulonephritis. The patient was treated with corticosteroids and pulses of cyclophosphamide followed by azathioprine and trimethoprim-sulfamethoxazole. After a follow-up of 10 months, the renal outcome was favorable with improvement of renal function but there was persistence of exorbitism and loss of visual function. Our case suggests that WG should be considered in the differential diagnosis of persistent bila-teral exophthalmos. Prompt recognition of this early manifestation is important for the institution of early treatment.

    A clinical case of non-obstructive hypertrophic cardiomyopathy with involvement of the right ventricle is reported. The patient was a 42-year-old male with symptoms suggesting an effort angina of recent onset. The diagnosis was established by echocardiography, which showed asymmetric hypertrophy of the interventricular septum (20 mm), hypertrophy of the right ventricular free wall, and severe hypertrophy of the septal papillary muscle of the tricuspid valve. The patient underwent a complete diagnostic evaluation, including exercise stress test, Holter monitoring, magnetic resonance, myocardial tomoscintigraphy and complete hemodynamic assessment. Medical treatment with atenolol 50 mg day was started; at 1-year follow-up the patient's clinical conditions are good, with decrease of anginal episodes. The literature review elicits the paucity of information about this condition, despite a frequent involvement of both ventricles in hypertrophic obstructive cardiomyopathy. The case reported shows two atypical aspects: a) the involvement of the right ventricle in non-obstructive hypertrophic cardiomyopathy is anecdotal; b) this pattern of hypertrophy (right ventricular free wall/septal papillary muscle) has never been previously reported. Right ventricular involvement in patients with hypertrophic cardiomyopathy must be carefully investigated, because it may be more frequent than conventionally deemed.

    Salivary gland-type tumors have been rarely described in the thyroid gland. Mammary Analog Secretory Carcinoma (MASC) is a recently defined type of salivary gland carcinoma characterized by a t(12;15)(p13;q25) resulting in an ETV6-NTRK3 fusion gene. We report 3 cases of MASC involving the thyroid gland without clinical evidence of a salivary gland or breast primary; the clinico-pathologic characteristics are reviewed. Assessment for rearrangement of the ETV6 (12p13) locus was conducted by fluorescence in situ hybridization (FISH) on representative FFPE sections using an ETV6 break apart probe (Abbott Molecular, Des Plaines, IL, USA). The patients were two females (52 and 55 years-old) and 1 male (74 years-old). The tumors were poorly circumscribed solid white tan nodules involving the thyroid. Histologically, they were invasive and showed solid, microcystic, cribriform, and tubular growth patterns composed of variably bland polygonal eosinophilic cells with vesicular nuclear chromatin and conspicuous nucleoli. All three cases showed metastasis to lymph nodes; one case showed lateral neck involvement. The tumor cells were positive for S100 and mammaglobin. GATA-3 and PAX-8 were positive in 2 cases, one of which only focally so. All three cases were negative for TTF-1 and thyroglobulin. Rearrangement of the ETV6 locus was confirmed in all cases and a diagnosis of MASC rendered for each case. A site of origin distinct from the thyroid gland was not identified, with a median follow up of 24 months. MASC may rarely involve the thyroid gland. The origin of these lesions is unknown; while an origin from ectopic salivary gland-type cells is entertained, a metastatic origin from an occult primary cannot be definitively excluded at this time. Given the histologic (follicular-like microcystic pattern with colloid-like secretions and papillary pattern), immunophenotypic (PAX-8), and even molecular overlap, MASC can be mistaken for papillary thyroid carcinoma and should be

    服务创新是促进经济发展与增强企业竞争力的驱动力,而顾客在服务创新过程中扮演着十分重要的角色,了解和满足顾客需求已经成为服务创新一个重要的影响因素。随着顾客越来越广泛地参与到创新过程中,企业需要科学、合理地管理顾客参与,其中对顾客参与激励的管理问题尤为突出。借鉴内/外在动机理论,企业应挑选对服务创新具有较强内在参与动机的顾客参与并给予奖励,建立即时、有效的反馈机制,来自企业和其他顾客群体的社会认可及创新平台体验等是保持顾客参与积极性的手段,且这种激励不应限制或损害顾客参与的内在动机,不应降低顾客的创造力水平。借鉴机制设计理论思路,企业可设计相应的激励机制,使顾客群体能够感受到自己的创新努力得到保护和奖赏,迸发出最大的积极性和创造力,进而在参与服务创新时积极主动地创造有价值、新颖的服务产品。%Service innovation is a driving force in promoting economic development and strengthening firm-competency. Customers play the important role during the process of service innovation;understanding and satisfying customers demand has become an important influencing factor for service innovation. With customers increasingly involved into service innovation,the enterprises should scientifically and rationally manage customer participation,especially the incentive problems. Drawing on the theory of intrinsic and extrinsic motivation,the enterprises should choose customers with strong motivation of participation and grant them with rewards;timely and effective feedback system,recognition from enterprises and other customer groups,and the experience on innovation platform are all the incentive means for the enterprises to maintain customer motivation of participation. And all these incentives should not limit or hurt the intrinsic motivation of

    Full Text Available Involvement load hypothesis as a cognitive construct states that tasks with higher involvements yield better results in vocabulary retention. This comparison group designed study examined the immediate and delayed effects of tasks with different involvements in involvement load hypothesis (Laufer & Hulstijn, 2001. Applying a version of Nelson Proficiency Test as a homogenizing exclusion criterion, 33 low proficiency Iranian EFL learners were randomly assigned to three experimental groups: blank-filling, sentence making, and reading comprehension. The results of ANOVA and Kruskal-Wallis tests supported task-induced involvement in immediate posttest since the sentence making task (M=5.72 yielded better results in comparison with the other two blank-filling (M=5.45 and reading comprehension (M=3.18 tasks. Nevertheless, sentence making and blank-filling tasks of which the involvements were somehow similar did not yield significant superiority to each other. It is inferred that tasks with nearer involvements yield somehow similar results in vocabulary acquisition.

    Full Text Available Abstract Takayasu’s arteritis (TA is a form of chronic vasculitis that typically occurs in young adult Asian females, but it can also present in younger patients not fitting this classic profile. In these cases, the sequelae are generally similar to those found in adults. The disease predominantly affects the aorta and its primary branches. However, the coronary arteries are also affected in up to 20% of cases, which may precipitate myocardial infarction. Imaging of the coronary arteries therefore becomes critically important in the evaluation of a patient with possible Takayasu’s arteritis. We present a case of a pediatric patient with TA who had no symptoms of angina but who was found to have significant coronary artery involvement on diagnostic imaging. This necessitated tailoring of traditional management.

    2011-06-01

    Full Text Available Background: Placenta accreta is a life-threatening complication after previous cesarean delivery. The aim of this case report is to present a case of placenta percreta with bladder involvement and subsequent maternal death.Case presentation: The patient was a 37-year old who had an unwanted pregnancy due to tubectomy failure two years afterwards. She was hospitalized at 26th and 30th week of gestation because of gross hematuria. Sonography reported placenta previa. Cesarean section was performed at 34th gestational week. Due to severe hemorrhage, hysterectomy with resection of some part of the bladder was done. Died at the operating room after four hours of severe uncontrollable hemorrhage. Conclusion: The increasing prevalence of different forms of placenta accreta is the result of the ever-increasing rate of cesarean deliveries. One of the strategies to prevent this catastrophic obstetric complication is decreasing the number of cesarean deliveries without appropriate indications.

    Full Text Available Abstract Background Brucellosis is a multi-system disease that may present with a broad spectrum of clinical manifestations. While hepatic involvement in brucellosis is not rare, it may rarely involve the kidney or display with cardiac manifestations. Central nervous system involvement in brucellosis sometimes can cause demyelinating syndromes. Here we present a case of brucella hepatitis, myocarditis, acute disseminated encephalomyelitis, and renal failure. Case presentation A 26-year-old man presented with fever, ataxia, and dysarthria. He was a shepherd and gave a history of low grade fever, chilly sensation, cold sweating, loss of appetite, arthralgia and 10 Kg weight loss during the previous 3 months. He had a body temperature of 39°C at the time of admission. On laboratory tests he had elevated level of liver enzymes, blood urea nitrogen, Creatinine, Creatine phosphokinase (MB, and moderate proteinuria. He also had abnormal echocardiography and brain MRI. Enzyme-linked immunosorbent assay for IgG and IgM was negative. Standard tube agglutination test (STAT and 2-mercaptoethanol (2-ME titers were 1:80 and 1:40 respectively. Finally he was diagnosed with brucellosis by positive blood culture and the polymerase chain reaction for Brucella mellitensis. Conclusion In endemic areas clinicians should consider brucellosis in any unusual presentation involving multiple organ systems, even if serology is inconclusive. In endemic areas low STAT and 2-ME titers should be considered as an indication of brucellosis and in these cases additional testing is recommended to rule out brucellosis.

    Full Text Available School bullying is one of the main problems affecting the quality of peer relationships in schools and in general the coexistence. At European level, there are scientific findings that indicate its nature, characteristics and factors related to its involvement. However, in poor and developing countries, where the problem is more serious, there is a high degree of awareness on this matter. The present study aimed to identify what factors may be influencing the occurrence of bullying in a representative sample of primary schools in the Nicaraguan capital. For this propose, 3042 students from Managua and its metropolitan area were explored with instruments comparable to those used in Europe. A multinomial logistic regression analysis indicated that being a boy, to show antisocial behaviors and attitudes and contact with drugs were the three factors most related with the role of aggressor, as well as negative relationships had a significant influence on involvement in this phenomenon, either as a victim, aggressor or victimized aggressor. Results are discussed in relation to the profiles of aggressor and victim of bullying in international studies focusing on differences in developed countries.

    Wood, Jeffrey J; Repetti, Rena L

    2004-03-01

    Predictors of change in fathers' and mothers' perceptions of child caregiving involvement were examined. Middle-class 2-parent families (131 mothers and 98 fathers) with a target school-age child participated. Fathers and mothers completed annual questionnaires for 3 consecutive years. Latent growth curve modeling suggested that fathers were likely to increase their relative contribution to child caregiving over the course of 3 years when they had a greater proportion of male children in the family and when life events-particularly changes in employment and financial status-were experienced by the family. Although mothers were responsible for more of the caregiving, their relative level of involvement tended to decrease when there were no young children in the family. Two-parent families may adapt to varying family contexts and life circumstances by shifting caregiving roles and responsibilities over the course of years.

    2013-01-01

    Over the past two years, the Ombuds has seen double the number of cases involving women staff members compared to those involving men, relative to their populations. Two questions can thus be asked: is that a general phenomenon also seen in other organizations? Or is it related to the under-representation of women, namely is this a common situation in organizations with fewer women than men? If so, the Ombuds should notice different statistics in organizations where the number of women and men is comparable.   To answer these questions, several annual reports from international organizations have been analysed. The names of these organizations are kept confidential, as the reports are not public. Relation between the percentage of cases involving women and their percentage in an Organization. The circled data point is CERN’s. The results can be seen in this graph (right), limited solely by the number of Organizations for which such data is available. Note that if the ...

Group of Hospitals and Grant Medical College, Mumbai is reported. Pemphigus vulgaris constituted the single largest group of 43 cases, followed by pemphigus foliaceus (25 cases and pemphigus vegetans (2 cases. Majority of the cases were seen in the age group of 21-60 years, with a slight male predominance. The youngest patient was 14 years while the eldest was aged 75 years. Mucosal involvement was seen in 31 cases of pemphigus vulgaris, as opposed to only 5 cases of pemphigus foliaceus. Flaccid bullae were present in 100% cases. Pruritus was complained of in 14 cases, though it was more common in pemphigus vegetans and vulgaris. Salient histopathological features of pemphigus vulgaris observed were (I intraepidermal suprabasal blisters (35 cases, (2 presence of acantholytic cells (40 cases, (3 "Row of tombstone appearance" (I8 cases and (4 acantholysis involving follicular sheath (20 cases. Main histopathological features of pemphigus foliaceus were (1 subcorneal blister (15 case, (2 acantholysis (24 cases and (3 bulla cavity containing inflammatory infiltrate (12 cases. Both cases of pemphigus vegetans showed hyperkeratosis, papillomatosis and irregular acanthosis with intra-epidermal eosinophilic abscesses besides suprabasal lacunae.

    2015-01-01

    Full Text Available Mitral valve prolapse (MVP is usually asymptomatic, but can be associated with complications such as infective endocarditis, mitral regurgitation, thromboembolism and sudden cardiac death. It has been very rarely reported to occur in association with other valvular involvement. A 55-year-old male patient was brought dead and at autopsy the mitral valve orifice was stenotic and the leaflets were enlarged, myxoid and bulging suggestive of MVP and chordae tendinae were thickened, stretched and elongated. Similar changes were seen in the tricuspid valve. The pulmonary and aortic valves also showed myxomatous degeneration of their cusps. Myxomatous degeneration is the most common cause of MVP and it can be associated with involvement of the other valves. Concomitant involvement of the aortic valve has been reported, however it is very rare and simultaneous involvement of the pulmonary valve has not been reported in the literature so far. We report a case of MVP associated with myxomatous degeneration of the tricuspid, pulmonary and aortic valves.

    Relapsing polychondritis (RP) is an autoimmune disorder characterized by inflammation in cartilaginous structures including the ears, noses, peripheral joints, and tracheobronchial tree. It rarely involves the central nervous system (CNS) but diagnosis of CNS complication of RP is challenging because it can present with varying clinical features. Herein we report 3 cases of relapsing polychondritis involving CNS with distinct manifestations and clinical courses. The first patient presented with rhombencephalitis resulting in brain edema and death. The second patient had acute cognitive dysfunction due to limbic encephalitis. He was treated with steroid pulse therapy and recovered without sequelae.

    Emotional stresses and psychological disorders seem to be concurrent factors in some cases of prurigo nodularis (PN), a chronic skin condition with a difficult therapeutic approach. In order to improve the therapeutic strategies, we performed a psychometric study on 20 patients affected by generalized and histological proven PN. Specific questionnaires were employed to examine the hypotheses (General Health Questionnaire, State Trait Anxiety Inventory - form Y, Beck Depression Inventory-II, and Eysenck Personality Questionnaire). The results show that symptoms of anxiety and depression associated with PN are more severe than in the control group and that some specific traits of personality are more frequently represented in such subjects. The results of our study represent a first attempt to analyze the psychological problems and the personality dimensions which seem to characterize PN patients. Such evidence supports the importance of a psychological approach in the clinical management of PN, which should always include psychological assessment and treatment together with the other therapeutic options.

    Full Text Available Introduction. Behçet's disease (BD is a form of vasculitis of unknown etiology which is rare in our environment. It is characterized by a variety of clinical manifestations and usually affects young adults. Recurrent oral and genital ulcers are a characteristic and extremely frequent symptom, but mortality is linked with more significant symptoms such as aortic pseudoaneurysm, pulmonary pseudoaneurysm, and cerebral venous thrombosis. Patient and Method. We present a case of a young male with atypical BD and severe polyvascular involvement (previous cerebral venous thrombosis and current peripheral venous thrombosis, acute ischemia, and peripheral arterial pseudoaneurysm who required urgent surgical intervention due to a symptomatic external iliac pseudoaneurysm. Result. The pseudoaneurysm was successfully treated, we performed an iliofemoral bypass, and we treated it with steroids and immunosuppressive therapy. Conclusions. These rare clinical manifestations highlight the importance of considering BD in young patients, even in usual cases of vascular intervention, whether arterial or venous in nature.

    Full Text Available Malignant otitis externa is an inflammatory condition caused by pseudomonas infection usually in the elderly diabetics, or an immunosuppressive condition that presents with diffuse otitis externa along with excruciating pain and granulations tissue in the external auditory meatus. Facial paralysis is common along with occasional involvement of other cranial nerves. Case report describing a patient of malignant otitis externa who presented to a tertiary referral hospital of eastern India. This patient had ipsilateral facial and tenth cranial nerve paralysis along with delayed-onset contralateral sixth and twelfth cranial nerve palsy. The patient was treated initially with intravenous anti-pseudomonal antibody followed by tympanic platectomy, facial nerve decompression and medialisation thyroplasty. The contralateral cranial nerve palsy was managed conservatively with partial recovery of function. Malignant otitis externa, though a common disease, may occasionally present with uncommon or unexplained presentations. The management of these cases should be prompt and aggressive and specifically address each of the debilitating complications.

    Full Text Available This is a report of a case study on 234 patients with impetigo who referred to Razi Dermatology Hospital from April to November, 1989. Treatment was started immediately after obtaining direct smear and performing culture and antibiotic sensitivity test. The most common organism responsible for impetigo was the coagulase-positive staphylococcus (71%. In 13.7% of the cases, the coagulase-negative staphylococcus was grown on culture media, but none of the cultures showed streptococcus as the main organism. Treatment was started with oral penicillin V, oral erythromycin, benzathine penicillin G injection, oral cephalexin, and topical fuccidin. Clinical and bacteriological evaluation after 3-7 days showed that it is preferable to use oral cephalexin instead of other protocols such as oral erythromycin, which has previously been the drug of choice for impetigo. In addition, topical fuccidin with a 75% curative rate was the first drug for treatment, with the same effect as the oral cephalexin

    2011-04-01

    Full Text Available Abstract Introduction Laparoscopic port-site metastasis is a rare but well recognized outcome following surgery in urological cancers, with its etiology not clearly understood. Additionally, vaginal metastasis in clear cell renal cell carcinoma is rare, and has not been previously reported in the setting of papillary renal cell carcinoma. Case presentation We present the case of a 71-year-old Chinese woman with metastatic type II papillary renal cell carcinoma with histologically verified vaginal involvement and a concurrent laparoscopic port-site metastasis. This was also associated with a unique constellation of widely disseminated metastatic sites, which include a local relapse, the peritoneum and the urethra. Conclusion Laparoscopic port-site metastases are associated with the presence of advanced cancer with multiple sites of metastasis. We hypothesize from the findings of our report and background data that this phenomenon is more likely to be related to tumor factors rather than operative factors. We also present what is, to the best of our knowledge, the first reported case in the literature of vaginal and urethral metastasis and the second reported case of laparoscopic port-site recurrence.

    2015-01-01

    Full Text Available Herpesviruses can directly affect the structure of the nervous system, resulting in encephalitis, and also induce immune-mediated disorders of the peripheral nervous system as sensory-predominant chronic inflammatory demyelinating polyneuropathy (CIDP. Patients with immunodeficiency may simultaneously develop two pathological processes, determining the severity of the condition. Parainfectious limbic encephalitis (PILE associated with viruses from the family Herpes viridae is a form of chronic herpes encephalitis, which is characterized by dysfunction of the limbic system and by a long-term course with exacerbations. CIDP is a dysimmune disease leasing to peripheral nervous system involvement, which belongs to a class of myelinopathies. The paper describes two clinical cases of a concurrence of chronic PILE and CIDP in middle-aged men who have symptomatic status epilepticus and iatrogenic complications. It characterizes difficulties in diagnosis and the clinical features of chronic herpes infection involving the central and peripheral nervous systems. The given clinical cases suggest that not only neurologistsand epileptologists, but also resuscitation specialists and ngiosurgeons should be particularly alert to the pathology in question.

  6. Involvement of Kytococcus schroeteri in a case of prosthetic valve endocarditis

    Directory of Open Access Journals (Sweden)

    Antonella D’Andria

    2008-03-01

    Full Text Available We report a fourth case of prosthetic valve endocarditis caused by the newly described micrococcal species: Kytococcus schroeteri. A 38-year old male was admitted to our hospital with suspected prosthetic valve endocarditis. In three blood cultures and in the prosthetic heart valve culture grew the same type of microrganism, initially identified as Micrococcus luteus. Presuntive assignment to the genus Kytococcus was suggested by the arginina dihydrolase activity and by the resistence to penicillin, oxacillin and methicillin, characteristics which are not shared by other micrococci. Further biochemical tests confirmed that the isolates belonged to the genus Kytococcus (negative reaction for oxydase, esculin and urease, positive for catalase and arginine dihydrolase species schroeteri (alpha-glucosidase positive. The patient was treated with vancomycin, gentamicin and rifampicin. After the valve replacement, on the 20th day of hospitalization, the patient’s biological parameters returned to normal values, and after one mounth the resolution of the disease was completed. The diagnosis of four cases by K. schroeteri endocarditis, described within a short period of time (2003-2006, might indicate a specific pathogenicity of this new species. In case of endocarditis diagnosis, the suspect of the genus Kytococcus involvement should be considered each time the aerobic Gram positive cocci, with arginina dihidrolase activiy and the resistence to penicillin, oxacillin and methicillin, are isolated by significative biological samples.

  7. Study of Systemic Risk Involved in Mutual Funds

    Science.gov (United States)

    Dash, Kishore C.; Dash, Monika

    Systemic risk, may be defined as the risk that contaminates to the whole system, consisting of many interacting agents that fail one after another. These agents, in an economic context, could be firms, banks, funds, or other financial institutions. Systemic risk is a macroscopic property of a system which emerges due to the nonlinear interaction of agents on a microscopic level. A stock market itself is a system in which there are many sub-systems, like Dowjones, Nifty, Sensex, Nasdaq, Nikkei and other market indices in global perspective. In Indian market, subsystems may be like Sensex, Nifty, BSE200, Bankex, smallcap index, midcap index, S&P CNX 500 and many others. Similarly there are many mutual funds, which have their own portfolio of different stocks, bonds etc. We have attempted to study the systemic risk involved in a fund as a macroscopic object with regard to its microscopic components as different stocks in its portfolio. It is observed that fund managers do manage to reduce the systemic risk just like we take precautions to control the spread of an epidemic.

    2008-09-01

    The spectroscopic properties of interactions involving horseradish peroxidase (HRP) and Tb3+ in the simulated physiological solution was investigated with some electrochemical and spectroscopic methods, such as cyclic voltammetry (CV), circular dichroism (CD), X-ray photoelectron spectroscopy (XPS) and synchronous fluorescence (SF). It was found that Tb3+ can coordinate with oxygen atoms in carbonyl groups in the peptide chain of HRP, form the complex of Tb3+ and HRP (Tb-HRP), and then lead to the conformation change of HRP. The increase in the random coil content of HRP can disturb the microstructure of the heme active center of HRP, in which the planarity of the porphyrin cycle in the heme group is increased and then the exposure extent of the electrochemical active center is decreased. Thus Tb3+ can inhibit the electrochemical reaction of HRP and its electrocatalytic activity for the reduction of H2O2 at the Au/Cys/GC electrode. The changes in the microstructure of HRP obstructed the electron transfer of Fe(III) in the porphyrin cycle of the heme group, thus HRP catalytic activity is inhibited. The inhibition effect of Tb3+ on HRP catalytic activity is increased with the increasing of Tb3+ concentration. This study would provide some references for better understanding the rare earth elements and heavy metals on peroxidase toxicity in living organisms.

    Acute limb ischemia is a complication of severe peripheral arterial disease that can be a threatening limb as well as life. Multiple procedures exist today to help revascularize extremities; however, even with the latest technologies, surgical amputation of the limb may still be necessary. Cryoamputation, or physiologic amputation, is a method used to treat patients who are hemodynamically unstable for the operating room and who are in need of urgent amputation owing to arterial ischemia. This procedure is used in the rare instance where not only a persons' limb is threatened, but also their life. This is a case study regarding one patient who presented to the hospital with limb-threatening ischemia who became hemodynamically unstable owing to the rhabdomyolysis associated with the ischemia of his lower extremity. Cryoamputation was used to stabilize the patient and prevent further deterioration, so that he could safely undergo surgical amputation of the limb without an increase in mortality risk. Cryoamputation must be followed by formal surgical amputation when the patient is hemodynamically stabilized. It is not a limb salvaging, procedure but it is a life-saving procedure. This case study demonstrates the usefulness of the procedure and discusses the technique used for cryoamputation.

    Erdheim Chester disease is a rare non-Langerhans cell histiocytosis which may involve multiple organs including bone, soft tissue, lungs, cardiovascular system, kidneys (retroperitoneum), skin, and central nervous system. Bone involvement is most common followed by other organs. This case report describes a 58-year-old man who presented with progressive renal dysfunction presumed due to obstruction. The patient failed multiple urinary tract interventions, and clinical course was complicated by recurrent low-grade fevers, and bilateral knee pain. Advanced imaging and histopathological features on bone biopsy were consistent with Erdheim Chester disease. Molecular studies of tissue showed BRAF V600 mutation. This patient was treated with Zelboraf (vemurafenib) BRAF inhibitor with subsequent improvement in renal and pleural dysfunction as well as decreased histiocytic soft tissue masses on CT. (orig.)

    2009-04-01

    Full Text Available Abstract A dog presented with cutaneous nodules, enlarged lymph nodes and oedema in limbs, face and abdomen. The diagnosis of visceral leishmaniasis was established by identification of Leishmania amastigotes within macrophages from skin and popliteal lymph node biopsies. At necropsy, lesions were found in different organs, but it was particularly striking to observe large areas of pallor in the myocardium. Histological examination revealed an intense chronic inflammatory reaction in many organs, and numerous macrophages were found to contain amastigote forms of Leishmania. The inflammatory reaction was especially severe in the heart, where large areas of the myocardium appeared infiltrated with huge numbers of mononuclear immune cells, causing cardiac muscle atrophy and degeneration. Despite the severe inflammation, the number of parasitized macrophages was low in the myocardium, as revealed by immunohistochemical staining of Leishmania amastigotes. Because cardiac involvement is not usually described in this condition, this dog represents a very rare case of canine visceral leishmaniasis with affection of the myocardium.

    Purpose: To describe a case of Erdheim-Chester disease with bilateral orbital involvement.Methods: A 43-year-old female with bilateral proptosis was presented. Its clinical features, image findings, pathological character and therapeutic effect were evaluated.Results: CT demonstrated bilateral, diffuse orbital mass. Histopathologic assessment revealed a diffuse xanthogranulomatous process with clusters of lipidladen histocytes. Numerous Touton giant cells were scattered throughout the lesion. Renal and heart failure happened during a 6-year follow-up period. Long bones roentgenogram demonstrated diffuse symmetrical sclerosis with extensive, lytic lesions. Systemicadministration of corticosteroids, chemotherapy, immunoglobulin and traditional Chinese medicine showed good therapeutic result. Conclusions: An administration of systemic corticosteroids, chemotherapy, immuno- globin and traditional Chinese medicine can control Erdheim-Chester disease. Further exploration of its pathogenesis and collection of useful clinical data are required.

    Case studies can be useful in assessing and learning lessons from emergency situations. In this paper, different uses for disaster case studies, are explored with identification of potential pitfalls that should be avoided. In addition, ways to improve the rigor and significance of case studies are suggested. Case studies can be used as examples or as a research tool. If conducted properly, they can provide robust and compelling results. It is argued that sharing a common guide to conducting and writing case studies among all disaster risk reduction professionals could improve the quality of case study reports and thereby strengthen their value in advancing the prevention, preparedness, and management of disasters and emergencies.

    Several articles have highlighted the potential involvement of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) in neurodegeneration by showing a non-glycolytic activity of GAPDH specifically in the brains of subjects with Alzheimer's disease (AD). The novel aim of this study was to elucidate the critical role of GAPDH and its interaction with β-amyloid in the blood of Moroccan patients with familial AD (FAD) carrying presenilin mutations and in sporadic late onset AD (LOAD). Our results show a significant decrease in the activity of GAPDH in blood samples from patients with FAD as compared to sporadic cases and healthy controls. The expression level of GAPDH in brain specimens from mutant tau transgenic mice and patients with FAD was unchanged as compared to healthy controls. In contrast, the expression level of GAPDH in blood samples from mutant tau transgenic mice and patients with FAD was decreased as compared to sporadic cases and healthy controls. Moreover, there is an accumulation of β-amyloid aggregates in the blood samples of patients with FAD and an increase in amyloid fibrils in both the blood and brain samples of these patients. Our study adds new insight to previous ones by showing the involvement of GAPDH in AD, which may influence the pathogenesis of this neurodegenerative disease.

    The Global Hydrology and Climate Center and NASA's Marshall Space Flight Center conducted a fact-finding case study for the Data Management Working Group (DMWG), now referred to as the Data and Information Working Group (DIWG), of the U.S. Global Change Research Program (USGCRP) to determine the feasibility of an interagency National Environmental Change Information System (NECIS). In order to better understand the data and information needs of policy and decision makers at the national, state, and local level, the DIWG asked the case study team to choose a regional water resources issue in the southeastern United States that had an impact on a diverse group of stakeholders. The southeastern United States was also of interest because the region experiences interannual climatic variations and impacts due to El Nino and La Nina. Jointly, with input from the DIWG, a focus on future water resources planning in the Apalachicola-Chattahoochee-Flint (ACF) River basins of Alabama, Georgia, and Florida was selected. A tristate compact and water allocation formula is currently being negotiated between the states and U.S. Army Corps of Engineers (COE) that will affect the availability of water among competing uses within the ACF River basin. All major reservoirs on the ACF are federally owned and operated by the U.S. Army COE. A similar two-state negotiation is ongoing that addresses the water allocations in the adjacent Alabama-Coosa-Tallapoosa (ACT) River basin, which extends from northwest Georgia to Mobile Bay. The ACF and ACT basins are the subject of a comprehensive river basin study involving many stakeholders. The key objectives of this case study were to identify specific data and information needs of key stakeholders in the ACF region, determine what capabilities are needed to provide the most practical response to these user requests, and to identify any limitations in the use of federal data and information. The NECIS case study followed the terms of reference

    Full Text Available Concentrated Photovoltaics (CPV, once a niche technology, has now reached the maturity and reliability for large scale power generation. Especially in regions where temperatures are very high, the use of high efficiency triple junction solar cells with concentrating optics allows stable energy yield. Thus CPV can be seen as complementary and not in concurrence with silicon photovoltaics. The state of the art, the advantages and limitations of this technology will be shown. Among the main advantages of CPV is the possibility of a much higher energy supply, when compared to silicon photovoltaics, both comparing CPV and silicon with same area or the same installed power. The use of recycled and recyclable materials allows a more environmentally friendly production. The possibility to couple CPV with desalination facilities, energy storage will be analysed. As an example a case study of a CPV installation in Northern Italy is discussed. Here the use of mature technologies, derived from automotive and lighting sectors resulted in a simple and efficient module.

    2014-02-01

    Rates of survival after cardiac arrest are low and correlate with the quality of cardiopulmonary resuscitation (CPR). Devices that deliver automated CPR (A-CPR) can provide sustained and effective chest compressions, which are especially useful during patient transfer and while simultaneous invasive procedures are being performed. The use of such devices can also release members of resuscitation teams for other work. This article presents a case study involving a man with acute myocardial infarction complicated by cardiogenic shock and pulmonary oedema. It describes how ED nursing and medical teams worked together to deliver A-CPR, discusses the use of A-CPR devices in a tertiary cardiac centre, and highlights the advantages of using such devices.

    1983-01-01

    Seventeen cases of late ulnar paralysis treated by neurolysis-transposition are reported. The clinical characteristics of these paralysis are emphasized. A very prolonged symptom free interval, a rapid onset and a severe involvement. The ulnar transposition was most often done subcutaneously. Cubitus valgus and definite nerve compression proximal to the arcade of the flexor carpi ulnaris muscle are almost always present. The results as regards the neuropathy are notable: no patient is completely cured and only half are improved. An anatomical study of the nerve path shows the essential role, in the compression of the nerve, of the muscular arcade of the flexor carpi ulnaris muscle which acts in a way similar to the bridge of a violin. Hence, opening it longitudinally is the principal procedure of the neurolysis. This should be routine before the first signs of neuropathy occur in an elbow whose axis is out of alignment as a sequela of a childhood injury.

    Primary angiitis of the central nervous system is a rare condition, usually with an insidious onset. There is a wide variety of histological types (granulomatous, lymphocytic or necrotizing vasculitis) and types of vessel involved (arteries, veins or both). Most cases are idiopathic. We describe a first case of idiopathic granulomatous central nervous system phlebitis with additional limited involvement of the heart and lung, exclusively affecting small and medium sized veins in a 22-year-old woman, presenting as a sub acute headache. The reasons for this peculiar limitation of inflammation to the veins and the involvement of the heart and lungs are unknown.

    Objectives: To study the prevalence and characteristics of renal and perirenal space involvement and its relation to the severity of acute pancreatitis (AP) using MRI. Methods: 115 patients with AP who underwent MRI with the clinical kidney function test were retrospectively analyzed in this study. MRI sequences included conventional and diffusion weighted imaging (DWI) sequences. The renal and perirenal space involvement in AP was noted on MRI. The renal apparent diffusion coefficient (ADC) on DWI was measured for each kidney. The severity of AP on MRI was graded using MR severity index (MRSI). The relationships among the renal and perirenal space involvement on MRI, the renal ADC, MRSI and the results of the kidney function test were analyzed. Results: In the 115 patients with AP, the renal and perirenal space abnormalities detected included renal parenchymal abnormalities (0.8%), abnormalities of the renal collecting system (2.6%), renal vascular abnormalities (1.7%), thickened renal fascia (99%), perirenal stranding (62%) and perirenal fluid collection (40%). The prevalence of perirenal space abnormalities was correlated with the severity of AP based on MRSI (P < 0.05). The renal ADC values were lower in patients with abnormal kidney function than in those without kidney injury (P < 0.05). The prevalence of kidney function abnormalities was 9.4%, 32% and 100% in mild, moderate, and severe AP cases, respectively (P = 0.00). Conclusion: Perirenal space involvement is much more than renal parenchymal involvement in AP. The prevalence of perirenal space involvement in AP on MRI has a positive correlation with the severity of AP according to MRSI.

  20. A drug rape case involving triazolam detected in hair and urine.

    2012-07-01

    In recent years, there has been heightened awareness regarding the use of drugs to modify a person's behavior to facilitate crime. A drug rape case involving the potent, short-acting sedative triazolam will be presented. On three occasions, the victim consumed green tea and chocolate before being massaged and ultimately sexually abused. Screening for alcohol, commonly used drugs and illicit substances in blood and urine sampled during the forensic examination 20 h after the last incident, was negative. Consequently, hair samples for chemical analysis were taken from the assaulted individual 34 days after the last incidents. The hair was cut into three 2-cm segments (0-6 cm) that were washed, dissolved in extraction solvent and screened and verified by ultra performance liquid chromatography coupled with time of flight mass spectrometry (UPLC-TOF-MS) and with tandem mass spectrometry (UPLC-MS/MS), respectively. In the 2-cm hair segment corresponding to the period of the alleged assaults, the presence of the sedative triazolam was revealed at a concentration of 1.0 pg/mg hair. The preserved urine sample, taken 20 h after the last incident, was reanalyzed by UPLC-MS/MS for metabolites of triazolam, and 39 μg/l α-hydroxytriazolam was detected in the hydrolyzed urine. This case illustrates that hair is a valuable forensic specimen in situations where natural processes have eliminated the drug from typical biological specimens due to delays in the crime being reported. Furthermore, it was possible to verify the hair finding with a urine sample by detection of a metabolite of triazolam.

  1. Cerebral involvement in a patient with Goodpasture's disease due to shortened induction therapy: a case report

    Directory of Open Access Journals (Sweden)

    Preul Christoph

    2009-11-01

    Full Text Available Abstract Introduction Goodpasture's disease is a rare immunological disease with formation of pathognomonic antibodies against renal and pulmonary basement membranes. Cerebral involvement has been reported in several cases in the literature, yet the pathogenetic mechanism is not entirely clear. Case presentation A 21-year-old Caucasian man with Goodpasture's disease and end-stage renal disease presented with two generalized seizures after a period of mild cognitive disturbance. Blood pressure and routine laboratory tests did not exceed the patient's usual values, and examination of cerebrospinal fluid was unremarkable. Cerebral magnetic resonance imaging (MRI revealed multiple cortical and subcortical lesions on fluid-attenuated inversion recovery sequences. Since antiglomerular basement membrane antibodies were found to be positive with high titers, plasmapheresis was started. In addition, cyclophosphamide pulse therapy was given on day 13. Encephalopathy and MRI lesions disappeared during this therapy, and antiglomerular basement membrane antibodies were significantly reduced. Previous immunosuppressive therapy was performed without corticosteroids and terminated early after 3 months. The differential diagnostic considerations were cerebral vasculitis and posterior reversible encephalopathy syndrome. Vasculitis could be seen as an extrarenal manifestation of the underlying disease. Posterior reversible encephalopathy syndrome, on the other hand, can be triggered by immunosuppressive therapy and may appear without a hypertensive crisis. Conclusion A combination of central nervous system symptoms with a positive antiglomerular basement membrane test in a patient with Goodpasture's disease should immediately be treated as an acute exacerbation of the disease with likely cross-reactivity of antibodies with the choroid plexus. In our patient, a discontinuous strategy of immunosuppressive therapy may have favored recurrence of Goodpasture's disease.

    Morbus Behcet is a very infrequent multi-system disease caused by an immunological vasculitis affecting the arteries and veins. The disease is primarily known in Israel, Turkey, Italy, Great Britain and Japan. It may become manifest as erythema nodosum, polyarthritis, thrombophlebitis, occlusive arterial disease, pulmonary infarction, ulcerous colitis, portal hypertension, or via neurological symptoms (collateral symptoms), and it is not possible to make a clear prognosis. The most frequent signs of the neuro-Behcet syndrome, as in the case reported, is a meningoencephalitis. MRI is an essential modality for diagnosis and follow-up of the disease. In this case, the findings included meningeal irritations as well as an abduction deficit indicating involvement of the brain stem of type 1. As described in the literature, pathologic findings have been obtained by spinal fluid tests, showing increased cell number and proteins and pleocytosis of the granulocytes. (Orig./vhe) [Deutsch] Der Morbus Behcet ist eine seltene Multisystemerkrankung in Form einer immunvermittelten Vaskulitis, die Arterien und Venen betrifft. Die Erkrankung findet man ueberwiegend in Israel, der Tuerkei, Italien, Grossbritannien und Japan. Die Erkrankung ist multisystemisch, kann sich als Erythema nodosum, Polyarthritis, Thrombophlebitis, arterielle Verschlusskrankheit, Lungeninfarkt, ulzeroese Colitis, portale Hypertension oder mit neurologischen Symptomen (Nebensymptome) manifestieren, und basiert auf einer immunvermittelten Vaskulitis mit unklarer Prognose. Am haeufigsten manifestiert sich das Neuro-Behcet-Syndrom, wie beim untersuchten Patienten, in Form einer Meningoenzephalitis. Hierbei fand sich neben meningealen Reizsymptomen ein Abduktionsdefizit als Zeichen der Hirnstammbeteiligung im Sinne eines Typ 1. Wie in der Literatur beschrieben, zeigte sich ein pathologischer Liquorbefund mit Zellzahl- und Proteinerhoehung sowie granulozytaerer Pleozytose. Beim Neuro-Behcet, wie bei den anderen

    Gingival recession causes not only aesthetic problems, but problems with oral hygiene, plaque accumulation, speech, and tooth sensitivity. Replacing the missing gingival tissue with composite resin, when indicated, can be a time- and cost-effective solution. Here we report the case of a 25-year-old female who presented with generalized gingival recession. Black triangles were present between the maxillary and mandibular anterior teeth due to loss of interdental tissues, caused by recent periodontal surgery. She also had slightly malposed maxillary anterior teeth. The patient elected to replace gingival tissue with pink composite resin and to alter the midline with composite resin veneers. The first treatment phase involved placement of pink gingival composite to restore the appearance of interdental papilla to her upper (16, 15, 14, 13, 12, 11, 21, 22, 23, and 24) and lower (34, 33, 32, 31, 41, 42, 43, and 44) teeth. Phase two was to place direct composite resin bonded veneers on her upper (16, 15, 14, 13, 12, 11, 21, 22, 23, and 24) teeth to alter the midline and achieve desired colour. The third treatment phase was to level the lower incisal edge shape by enameloplasty (31, 32, 41, and 42) to produce a more youthful and attractive smile. This case report and brief review attempt to describe the clinical obstacles and the current treatment options along with a suggested protocol. Use of contemporary materials such as gingival coloured composite to restore lost gingival tissue and improve aesthetics can be a simple and cost-effective way to manage patients affected by generalized aggressive periodontitis (AgP).

    The teaching of biomaterials as case study by on-line platform , susceptible to develop both individually and in groups, got different objectives proposed by the European Higher Education System, among which include: participate actively in the teaching-learning process by students, interpreting situations, adapt processes and solutions. It also improves oral and written communication, analytical skills and synthesis and also the ability to think critically. Biomaterials have their origin in biominerals. These are solid inorganic compounds of defined structure, consisting of molecular control mechanisms that operate in biological systems. Its main functions are: structural support, a reservoir of essential elements, sensors, mechanical protection and storage of toxic elements. Following the demand of materials compatible with certain functional systems of our body, developed biomaterials. Always meet the condition of biocompatibility. Should be tolerated by the body and do not provoke rejection. This involves a comprehensive study of physiological conditions and the anatomy of the body where a biomaterial has to be implemented. The possibility of generating new materials from biominerals has a major impact in medicine and other fields could reach as geology, construction, crystallography, etc. While the study of these issues is in its infancy today, can be viewed as an impact on the art and future technology. Planning case study that students would prepare its report for discussion in subgroups. Occurs then the pooling of individual analysis, joint case discussion and adoption by the subgroup of a consensual solution to the problem. The teacher as facilitator and coordinator of the final case analysis, sharing leads to group-wide class and said the unanimous decision reached by the students and gives his opinion on the resolution of the case.

    Full Text Available Basal cell carcinoma (BCC is the most common cutaneous malignancy among Caucasians. Rare examples of aggressive and neglected BCC have been reported. Here we report a unique case of a neglected BCC with significant jaw involvement. A 50-year-old female, referred by an otorhinologist, presented with a large ulcer on her chin, which was extended to her mandibular vestibule. The ulcer was 9×5.5 cm in size, and tissue destruction, necrosis was observed in the central portion, and the mandibular bone was exposed. On intraoral examination, tooth mobility and severe bone loss were evident. Due to the primary cutaneous origin of the lesion, BCC was considered as preliminary diagnosis. Biopsy was performed and diagnosis of BCC was confirmed. The diseased mandibular bone was resected and reconstructed with a surgical plate. The soft tissue defect was reconstructed with deltopectoral flap. The patient refused secondary stage plastic surgery. Although BCC is not a lethal malignancy, if left untreated and neglected, it can result in severe destruction, disfigurement, and even mortality.

    2015-01-01

    Full Text Available The term juvenile ossifying fibroma (JOF is used in literature in naming two microscopically distinct fibro-osseous lesions of the craniofacial skeleton. One is characterized by small uniform spherical ossicles resembling psammoma bodies (psammomatoid JOF [PsJOF]. The other is distinguished by trabeculae of fibrillary osteoid and woven bone (trabecular JOF. Psammomatoid ossifying fibromas represent a unique subset of fibro-osseous lesions of the craniofacial region. PsJOF has been distinguished because of its location, clinical behavior, and age of occurrence. They have distinctive histomorphologic features and a tendency toward locally aggressive behavior, including invasion and destruction of adjacent anatomic structures. It is generally seen in the younger age group, and the most common site is paranasal sinuses, orbits, and frontoethmoidal complex. We report a case of JPOF involving mandible which is rarely been described in literature. An insight into the radiographic progression of this rare entity along with the clinical feature and surgical management is discussed.

    The aim of this article was to describe a rare case of paradental cyst of the permanent mandibular second molar. A 14-year-old girl was referred to Oral Surgery Department, Dental Clinic, IRCSS Fondazione Ca' Granda, University of Milan, Italy, for the evaluation of the deep probing located on the buccal aspect of her erupted mandibular left second molar. Clinical signs of inflammation were absent and the mucosa around the second molar appeared clinically normal. Pulp tests for the second molar were positive. The evaluation of the panoramic radiograph did not revealed radiolucency. The Cone-beam tomography showed a well-defined semilunar-shaped radiolucency demarcated by a fine radiopaque line. The cyst was enucleated. The histopathologic analisys revealed the presence of hyperplastic, non-keratinized squamous epithelium with heavy, dense inflammatory cell infiltrate in the epitelium and connective tissue wall. This analysis associated with macroscopic, clinical and radiografic examination confirmed the diagnosis of paradental cyst. A clinic-pathologic correlation, incorporating the surgical, radiographic and histologic findings, is required to obtain the final diagnosis of paradental cyst. Today, the treatment of choice is simple enucleation and thorough curettage of the cyst without extraction of the involved tooth, but if CT demonstrates erosions in the buccal or lingual cortices, marsupialization should be the treatment of choice.

    This paper describes the responses of undergraduate nursing students to an ethical clinical case study. Students in a baccalaureate program were given a case study before a lecture on ethical principles and the same case study after this lecture. These responses raise questions about the content of nursing ethics classes in Japan. The place of individual patient rights and the role of the family in a situation of non-disclosure about diagnosis and prognosis were major issues for the students. The responses reveal the problem of the 'nurse-in-the-middle' between the patient and others whose values differ. Students' post-lecture responses emphasized communication among the people involved.

    Full Text Available OBJECTIVE: To assess children with myocarditis, the frequency of various presenting symptoms, and the accuracy of different investigations in the diagnosis. METHODS: This was an observational study of 63 patients admitted to PICU with non-cardiac diagnosis. Cardiac enzymes, chest-X ray, echocardiography, and electrocardiogram were performed to diagnose myocarditis among those patients. RESULTS: There were 16 cases of definite myocarditis. The age distribution was non-normal, with median of 5.5 months (3.25-21. Of the 16 patients who were diagnosed with myocarditis, 62.5% were originally diagnosed as having respiratory problems, and there were more females than males. Among the present cases, the accuracy of cardiac enzymes (cardiac troponin T [cTn] and creatine phosphokinase MB [CKMB] in the diagnosis of myocarditis was only 63.5%, while the accuracy of low fractional shortening and of chest-X ray cardiomegaly was 85.7 and 80.9%; respectively. Cardiac troponin folds 2.02 had positive predictive value of 100%, negative predictive value of 88.7%, specificity of 100%, sensitivity of 62.5%, and accuracy of 90.5%. CONCLUSIONS: Children with myocarditis present with symptoms that can be mistaken for other types of illnesses. When clinical suspicion of myocarditis exists, chest-X ray and echocardiography are sufficient as screening tests. Cardiac troponins confirm the diagnosis in screened cases, with specificity of 100%.

    Inner ear bone malformations are one cause of profound sensorineural hearing loss. This investigation focused on those affecting the posterior labyrinth, especially enlarged vestibular aqueduct syndrome, which is associated with fluctuating and progressive hearing loss. The objectives of this study were to analyze the behavior of the electrical stimulation, auditory functionality and linguistic development in patients with inner ear malformations involving the posterior labyrinth. The study included ten patients undergoing cochlear implantation (cases: five with enlarged vestibular aqueduct, two with vestibular aqueduct stenosis/aplasia, and three with semicircular canal disorders). Post-implantation, data were gathered on the electrical stimulation threshold and maximum comfort levels and on the number of functioning electrodes. Evaluation of Auditory Responses to Speech (EARS) subtests were used to assess auditory functionality and language acquisition at 6, 12, and 24 months post-implantation. Results were compared with findings in a control group of 28 cochlear implantation patients without these malformations. No significant differences were found between case and control groups in electrical stimulation parameters; auditory functionality subtest scores were lower in cases than controls, although the difference was only statistically significant for some subtests. In conclusion, cochlear implantation patients with posterior labyrinth bone malformations and profound hearing loss, including those with enlarged vestibular aqueduct syndrome, showed no significant difference in electrical stimulation threshold with controls. Although some auditory functionality test results were lower in cases than in controls, cochlear implantation appears to be beneficial for all patients with these malformations.

    Full Text Available BACKGROUND AND OBJECTIVES: This study shows how the diffusion of the anesthetic into the sheath occurs through the axillary infraclavicular space and hence proves the efficacy of the anesthetic block of the brachial plexus, and may thereby allow a consolidation of this pathway, with fewer complications, previously attached to the anesthesia. MATERIALS AND METHODS: 33 armpits of adult cadavers were analyzed and unfixed. We injected a solution of neoprene with latex dye in the infraclavicular space, based on the technique advocated by Gusmão et al., and put the corpses in refrigerators for three weeks. Subsequently, the specimens were thawed and dissected, exposing the axillary sheath along its entire length. RESULTS AND DISCUSSION: Was demonstrated involvement of all fasciculus of the plexus in 51.46%. In partial involvement was 30.30%, 18.24% of cases the acrylic was located outside the auxiliary sheath involving no issue. CONCLUSIONS: The results allow us to establish the infraclavicular as an effective and easy way to access plexus brachial, because the solution involved the fascicles in 81.76% partially or totally, when it was injected inside the axillary sheath. We believe that only the use of this pathway access in practice it may demonstrate the efficiency.

    Fifteen patients with Sjoegren's syndrome without clinical evidence of central nervous system disease were studied by MRI. Signal abnormalities were observed in 9 (60%). They were always visible on T2-weighted images as small punctale areas of high signal in the basal ganglia and the white mater of the cerebral hemispheres. Abnormalities were less frequently seen on T1-weighted images. Enlargement of cerebral sulci was observed in 6 cases. The specificity and significance of these abnormalities are discussed. (orig.)

    We selected three case studies to illustrate environmental injustice issues in the South. These examples relate to migrant agricultural workers, the maquiladora industry and artisanal mining, while reviewing some of the major mechanisms involved, e.g. multinational corporations, the development of free trade zones, multilateral free trade agreements and the export of hazards. A series of strategies are discussed in order to address environmental injustice and health disparities that exist on a global scale. Some of the recommendations involve policy initiatives; others, such as research and mentorship, fall within the traditional domain of public health practice. In this paper, special attention is given to concerned environmental and occupational health professionals using evidence-based data for advocacy. For lasting changes to be made, however, stronger institutions and legislation are required. Those who have the 'right to know' about environmental injustice issues include communities of concern, workers' representatives and lawyers. Government officials and company officials may eventually work on the basis of conflict resolution, compensation and remediation, to quote some examples. Systematic approaches to protect both the environment and public health must be updated.

    2014-01-01

    Lingual mandibular bone defects, also known as Stafne bone cavity (SC), are unilateral asymptomatic radiolucencies, generally seen in the mandibular angle, below the inferior alveolar canal. Although panoramic radiographies normally offer enough information to make a correct diagnosis, additional studies are often required, especially in atypical cases. The present report describes an atypical presentation of a Stafne’s bone cavity in a 78 years-old male patient. In this particular case, an asymptomatic and radiolucid lesion was observed during a routine dental examination. The computed tomography (CT) showed an involvement of both lingual and buccal mandibular plates producing a tunnel-like lesion. No history of mandibular trauma or surgery was refered. An additional magnetic resonance imaging (MRI) was made to discard submandibular gland pathology and to confirm the diagnosis. Since SC is asymptomatic and nonprogressive, a conservative approach based in clinical and radiological follow-ups was considered to be the most suitable treatment option. Key words:Stafne bone cavity, lingual mandibular bone defect, case report. PMID:24596643

    Full Text Available Means of accommodation involve a wide range of social actors and agents, as well as different business models. Management strategies in this sector have been increasingly important for long-term sustainability and competitiveness of business organizations. This study aims to analyze the interactions between apart-hotels and their stakeholders to foster an improvement of services provided, aligning the interface of strategic management from the point of view of managers and their key stakeholders. It is an exploratory study, with qualitative chacter, along with multiple case studies of the following establishments: Travel Inn, Hotels Slaviero and Etoile george v. Brazilian enterprises, which manage lodging facilities with apart-hotel concepts, combining features that enable comparative analysis of the study. For conceptual understanding, this study was based on literature about stakeholders, taking the work of Freeman (1984 and Freeman et al (2010 as main references. The research was conducted through semi-structured interviews with managers of lodging facilities and their key stakeholders and through direct observation and documentation. We found that not all groups of influence are considered in the planning of service flats. However, the organizations surveyed indicated that the market has realized the importance of the groups that exert influence and are influenced by their goals, and are therefore increasingly alert for integration of such groups in their strategic planning.

    Full Text Available Henoch-Schönlein purpura (HSP, characterized by non-thrombocytopenic purpura accompanied by arthritis/arthralgia, gastrointestinal and genitourinary system involvement is the most common vasculitis in childhood. Associated penile involvement is very rare in patients with genitourinary system involvement. We report a 4.5 year-old boy with penile involvement and arthritis after a shortduration remission of HSP. Prednisolone (1mg/kg/day, orally and conservative measures resulted in complete recovery within five days. In conclusion, steroid treatment could be administered in HSP children with penile involvement although controversial.

    We investigated a reported case of stingray Dasyatis americana misidentification not detected in a published study using the random amplified polymorphic DNA (RAPD) technique. If the referred specimen (landed by fisheries in Ceará, northeastern Brazil) was misidentified (as Dasyatis centroura) in the field, why did its RAPD data fail to clarify the mistake? Was it due to limitations of RAPD markers or perhaps to a taxonomic issue? Contrary to our initial expectations, neither of these hindered the detection of the misidentification. After reanalyzing the primary genetic data associated with the misidentified specimen (PCR gel photographs and/or matrices of presence/absence of markers for six RAPD primers), we found that the RAPD markers were sufficient to correctly assign the misidentified specimen to its proper species identity. In the original study, the specimen misidentification was neither noticed by the authors nor apparent in the published article due to how their results were interpreted and presented.

    Currently in the United States, the heavy majority of plug-in electric vehicle (PEV) sales have been in highly conducive, selected, metropolitan areas; opposed to more broad distribution across the country. The U.S. Department of Energy’s EV Everywhere Grand Challenge is looking carefully at the barriers and opportunities that exist to enable small and midsize communities to partake in the PEV market and benefit from the economic and environmental advantages of PEVs. In order to gain insight into these challenges and barriers, DOE selected a success story (i.e., Drive Electric Vermont) as the subject of this case study, as the state of Vermont is tied with Detroit, Michigan in having the highest percentage of 2014 (most recent complete data) PEV registrations for cold weather U.S. cities and has seen more than a sixfold increase in charging stations over the last three years. The overall objective of this case study was to use the lessons learned from Drive Electric Vermont to determine what activities are most effective at encouraging acquisitions of PEVs and deployment of charging infrastructure in small to midsize communities, prioritizing and sequencing their implementation, identifying robust means for extrapolation, and applying this understanding to other small to midsize communities across the nation. The Drive Electric Vermont Program was formed in 2012 with a goal of increasing the use of electrified transportation in Vermont through policy development, education and outreach, and infrastructure development. The Drive Electric Vermont Program can be broadly broken into four components: (1) strategic planning/leadership, (2) stakeholder/partnership development, (3) education and outreach, and (4) incentives. The early phases of the program focused heavily on strategic planning, and stakeholder and partnership development, followed by a transition to education and outreach activities, charging infrastructure development, and grant and incentive programs

    Full Text Available Hypereosinophilic syndrome represents a heterogeneous group of disorders with the common feature of prolonged eosinophilia of unknown cause and organ system dysfunction including the pulmonary system. Hypereosinophilic syndrome, with and without pulmonary involvement, in association with pregnancy is very rare, and to the best of our knowledge only one case of hypereosinophilic syndrome with pulmonary involvement during pregnancy has been previously reported in the medical literature. We describe a case of a patient with previously symptomatic hypereosinophilic syndrome with pulmonary involvement who experienced exacerbations of her disease during two consecutive pregnancies. To the best of our knowledge this is the first report which demonstrates a worsening effect of pregnancy on both eosinophil count and end organ involvement in a patient with previous diagnosis of hypereosinophilic syndrome.

    Full Text Available Systems analysis students seldom experience the practical difficulties of the initial investigation into a client’s requirements. They get little chance to practice the skills they need to investigate complex and confused problem situations, or to appreciate the wider organizational issues that can impact on a situation. This teaching case is designed to give students the opportunity to practice and apply investigation skills and to challenge them to consider the wider work environment when considering possible solutions to a problem situation. The case is conducted as a role-play, with students acting as systems analysts and teaching staff role-playing the clients. The students develop a report analyzing the client’s situation based on the issues that arise during the interviews. Feed-back sessions focus on discussing how well the students applied various interviewing strategies previously covered in lectures, and on the wider organizational problems that could impact proposed information system solutions.

Newer treatment modalities, such as gamma knife radiosurgery needs to be explored for these lesions. Three cases of intrasellar metastatic lesions were retrospectively reviewed. Presenting complaints, radiographic studies, operative procedure, and histopathological confirmation were recorded for each patient. All had an unknown primary malignancy prior to the presentation with the intrasellar lesion detected by magnetic resonance imaging (MRI. Presenting symptoms were diplopia with extraocular movement deficits in all patients. Transsphenoidal resection or biopsy was performed. Histopathological analysis revealed small cell carcinoma in two patients and plasmacytoma in one. All patients received postoperative radiation and/or chemotherapy. Survival following initial presentation was 2 months and 6 months for two of the patients; the third patient is alive at 2-month follow-up.

    Chronic myeloid leukemia (CML) is a hematopoietic stem cell disorder included in the broader diagnostic category of myeloproliferative neoplasms, associated with fusion by BCR gene at chromosome 22q11 to ABL1 gene at chromosome 9q34 with the formation of the Philadelphia (Ph) chromosome. In 2–10% of CML cases, the fusion gene arises in connection with a variant translocation, involving chromosomes 9, 22, and one or more different chromosomes; consequently, the Ph chromosome could be masked within a complex chromosome rearrangement. In cases with variant Ph translocation a deletion on der(9) may be more frequently observed than in cases with the classical one. Herein we describe a novel case of CML with complex variant Ph translocation involving chromosomes 9, 12, and 22. We present the hematologic response and cytogenetic response after Imatinib treatment. We also speculated the mechanism which had originated the chromosome rearrangement. PMID:25045550

    Acute calcific tendinitis of the shoulder is a well-known condition, but it is rare in the rectus femoris origin. Mostly reported cases were occurred in the reflected head of the rectus femoris, and only few cases were in the direct head of the rectus femoris. Intraosseous marrow involvement of calcific tendinitis is a more rare condition; it often goes misdiagnosed as an infection or a neoplasm. We report a rare, unusual case of acute calcific tendinitis of the direct head of the rectus femoris associated with intraosseous marrow involvement of calcification in anterior inferior iliac spine with serial CT and MRI findings. Aggressive osseous change may occur in acute calcific tendinitis of the rectus femoris as in this case which should be made an appropriate diagnosis to avoid unnecessary investigation and overtreatment like a surgery.

    Photography often represents the best method to collect and preserve evidence in forensic cases. This is especially true in forensic odontology with cases involving dental identification, human abuse and, perhaps most significantly, bitemark cases. Basic visible light photography is adequate in most dental identification cases; however, full spectrum digital photography is best utilized to collect all available evidence in cases of human abuse and bitemarks. This paper will discuss the types of photographic evidence that should be collected with various forensic odontological cases and the specific techniques utilized in full spectrum forensic digital photography. The use of full spectrum photography captures the forensic injuries using special techniques recording the injuries in each of the four resultant events that occur when light strikes skin.

Progression is slow and symptoms are clinically stable. Symptoms are seen in the second or third decades of life. In this study, we present a seven-year-old girl who was diagnosed and directed to the Physiotherapy Department at the age of 5 years and had unilateral proximal upper limb involvement. Family history of the case was recorded. Neurologic evaluation was performed. Range of joint motion, muscle shortness and strength, posture, extremity lengths, gait, timed performance, arm function, and motor and mental maturation were assessed. The physiotherapy program was designed progressively as strengthening and resistive exercises. Motor and mental developmental milestones were normal. There was no limitation in active or passive motion of all joints. She had more flexible joints, scapula alata, asymmetry between shoulder levels, and weakness on proximal muscles of the right upper extremity. In the follow-up assessment at eight months, there was no asymmetry between shoulder levels and scapular symmetry began to improve. Female gender and involvement restricted to one proximal upper limb are rare in the literature. This patient demonstrates the positive effects of physical therapy with early diagnosis of MMA. The rapid recovery of muscle weakness shows the importance of strengthening and resistive exercises applied to specific muscles in the treatment.

    The microstructure of a heterogeneous SiO{sub 2} submitted to a depolymerisation process is studied using Transmission Electron Microscope (TEM), Environmental SEM (ESEM), and X-ray diffraction (XRD). With ESEM the formation of micro domain induced by the dissolution phenomena is shown. XRD shows the formation of a halo that is associated with the formation of amorphous phase. The parameters 'position and FWHM' of the halo, enabled us to show the evolution of the disorderly phase when the reaction progresses. The hypothesis of formation of nanoparticles with different structural states was confirmed by the TEM.

    In December 1992, the US Department of Energy (DOE) directed that the Plutonium-Uranium Extraction (PUREX) Plant be shut down and deactivated because it was no longer needed to support the nation`s production of weapons-grade plutonium. The PUREX/UO{sub 2} Deactivation Project will establish a safe and environmentally secure configuration for the facility and preserve that configuration for 10 years. The 10-year span is used to predict future maintenance requirements and represents the estimated time needed to define, authorize, and initiate the follow-on decontamination and decommissioning activities. Accomplishing the deactivation project involves many activities. Removing major hazards, such as excess chemicals, spent fuel, and residual plutonium are major goals of the project. The scope of the PUREX Transition Project is described within.

    Abstract Langerhans cell histiocytosis (LCH) involving the thyroid gland is extremely rare. Currently, the diagnosis and therapeutic evaluation for LCH involving thyroid is a challenge. We reported a rare case of LCH involving thyroid, presenting as painless thyroid goiters, and successfully performed positron emission tomography/computed tomography (PET/CT) to make an accurate diagnosis and therapeutic evaluation for LCH. Although the histology or cytology is the golden standard for the diagnosis of LCH involving thyroid, the PET/CT should be keep in mind when LCH involving thyroid with inconclusive cytologic results. During the treatment of LCH, PET/CT can be performed to assess the therapeutic effect and select the most effective and reliable treatment for LCH. PMID:26554785

    Reirradiation is a potentially useful option for many patients with recurrent cancer. The purpose of this study was to review all recently published randomized trials in order to identify methodological strengths and weaknesses, comment on the results, clinical implications and open questions, and give advice for the planning of future trials. Systematic review of trials published between 2000 and 2015 (databases searched were PubMed, Scopus and Web of Science). We reviewed 9 trials, most of which addressed reirradiation of head and neck tumours. The median number of patients was 69. Trial design, primary endpoint and statistical hypotheses varied widely. The results contribute mainly to decision making for reirradiation of nasopharynx cancer and bone metastases. The trials with relatively long median follow-up confirm that serious toxicity remains a concern after high cumulative total doses. Multi-institutional collaboration is encouraged to complete sufficiently large trials. Despite a paucity of large randomized studies, reirradiation has been adopted in different clinical scenarios by many institutions. Typically, the patients have been assessed by multidisciplinary tumour boards and advanced technologies are used to create highly conformal dose distributions. (orig.)

    Although astronomy plays an important role in the most various outreach initiatives, as well as school science curricula, due to its strong visual component in knowledge acquisition, astronomy subjects are not entirely well addressed and accessed by visually impaired students and/or general public. This stresses the need of more tactile material production, still very scarce in an educational context whether formal or informal. This is a case study activity developed based on different schematic tactile images of several objects present in our solar system. These images in relief, highlight, through touch, several relevant features present in the different astronomical objects studied. The scientific knowledge is apprehended through the use of a tactile key, complemented with additional information. Through proper hands-on activities implementation and careful analysis of the outcome, the adapted images associated with an explanatory key prove to be a valuable resource in tactile astronomy domain. Here we describe the process of implementing such initiative near visually impaired students. The struggles and challenges perceived by all involved and the enrichment experience of engaging astronomy with visually impaired audiences, broadening horizons in an overall experience accessible to all.

  10. Case studies in conservation science

    Bisulca, Christina

    The research presented in this dissertation covers three separate topics of conservation as defined by the National Science Foundation: 1) Materials Stabilization, Strengthening, Monitoring, and Repair; 2. Understanding Material Degradation and Aging; and 3) Materials and Structural Characterization of Cultural Heritage Objects (the 'technical study'). The first topic is addressed through a study to assess the consolidant tetraethoxysilane for the stabilization of alum treated wood. Falling under materials degradation studies is a study published in American Museum Novitates to understand how environmental conditions affect the aging of fossil resins from five different deposits. Two separate studies are included in technical study of cultural heritage objects which comprises the third research area of materials characterization. The first is a survey of red dyes used in Chinese paintings from the Ming Dynasty to the Early Republic (1364-1911). The second is a study of the pigments, dyes and binders used in Hawaiian barkcloth (kapa) from the 19th century.

    This is the second report of a large case control study of lymphoma/leukaemia occurring in Yorkshire during 1979-84, and deals with chronic lymphocytic leukaemia presenting either in its haematological (CLL) or more solid lymphomatous (malignant lymphoma-lymphocytic or MLL) forms. In all, 330 cases and 561 controls were interviewed. The results support the concept that CLL/MLL is a condition of multiple aetiologies with evidence for genetic predisposition through an excess of family cases, immune perturbation demonstrated by excessive previous skin diseases and phenylbutazone use, and viral involvement shown by links with infectious diseases and multiple sclerosis.

    Full Text Available Research question: We are looking at the process of structuring an integrated care system as an innovative process that swings back and forth between the diversity of the actors involved, local aspirations and national and regional regulations. We believe that innovation is enriched by the variety of the actors involved, but may also be blocked or disrupted by that diversity. Our research aims to add to other research, which, when questioning these integrated systems, analyses how the actors involved deal with diversity without really questioning it. Case study: The empirical basis of the paper is provided by case study analysis. The studied integrated care system is a French healthcare network that brings together healthcare professionals and various organisations in order to improve the way in which interventions are coordinated and formalised, in order to promote better detection and diagnosis procedures and the implementation of a care protocol. We consider this case as instrumental in developing theoretical proposals for structuring an integrated care system in light of the diversity of the actors involved. Results and discussion: We are proposing a model for structuring an integrated care system in light of the enacted diversity of the actors involved. This model is based on three factors: the diversity enacted by the leaders, three stances for considering the contribution made by diversity in the structuring process and the specific leading role played by those in charge of the structuring process.  Through this process, they determined how the actors involved in the project were differentiated, and on what basis those actors were involved. By mobilizing enacted diversity, the leaders are seeking to channel the emergence of a network in light of their own representation of that network. This model adds to published research on the structuring of integrated care systems.

  1. Case studies--ergonomics in projects.

    Pikaar, Ruud N

    2012-01-01

    The aim of a series of sessions on Company Case Studies, is to learn from practical experiences, to give feed back to researchers on applicability of theories, methods and techniques, and last but not least, to market ergonomics. In order to learn from case material, reports need to be easy accessible and well structured. System ergonomics provides such a structure. Usually a project is not done twice, i.e. with and without ergonomics. Therefore, it is not possible to make comparisons and determine the impact of ergonomics directly. A different approach is needed. It has been suggested at the IEA2006 World Congress, to compile a database of published case studies, each case to be reported in a fixed report format and critically reviewed to enable generalizing the outcomes. This paper proposes such a format. At the IEA2012 World Congress 40 case studies have been accepted, representing applied ergonomics cases in manufacturing, process industries, aviation and logistic systems.

  2. Leishmaniasis in dogs: Case study

    2009-01-01

    Full Text Available The paper presents a case of leishmaniasis in a 2.5-month-old dog imported from France. The clinical examination established a generally poor state of health, expressed cachexia, atrophy of the temporal musculature, weakness of movement, as well as abnormally long and brittle nails. There was also hyperkeratosis of the nose tip and paws. A histological examination of biopsy sections of the altered skin parts showed inflammatory changes in the area of the dermis, together with infiltration of macrophages and a smaller number of lymphocytes, plasmocytes and neutrophil granulocytes in the area around the sebaceous glands and hair follicles. The determined changes correspond to superficial dermatitis. Edema followed by partial degeneration of connective-tissue fibers is observed in connective tissue. A smaller number of intracellular parasitic forms was established in mononuclear cells. A smaller number of oval amastigotes with round dark red nucleis were observed in sections stained using the Gimza method in the cytoplasm of macrophages located in the dermis, but also extracellularly. It was concluded that the dog was diseased with leishmaniasis on the grounds of the clinical picture and the microscopic findings.

    Prentice, Andrew M

    2009-01-01

    Africa is the final continent to be affected by the nutrition transition and, as elsewhere, is characterized by the paradoxical coexistence of malnutrition and obesity. Several features of the obesity epidemic in Africa mirror those in other emerging nations: it penetrates the richer nations and urban areas first with a strong urban- rural gradient; initially it affects the wealthy, but later there is a demographic switch as obesity becomes a condition more associated with poverty, and it shares many of the same drivers related to the increasing affordability of highly refined oils and carbohydrates, and a move away from subsistence farm work and towards sedentary lifestyles. Africa also has some characteristics of the obesity epidemic that stand out from other regions such as: (1) excepting some areas of the Pacific, Africa is probably the only region in which obesity (especially among women) is viewed culturally as a positive and desirable trait, leading to major gender differences in obesity rates in many countries; (2) most of Africa has very low rates of obesity in children, and to date African obesity is mostly an adult syndrome; (3) Africans seem genetically prone to higher rates of diabetes and hypertension in association with obesity than Caucasians, but seem to be relatively protected from dislipidemias; (4) the case-specific deaths and disabilities from diabetes and hypertension in Africa are very high due to the paucity of health services and the strain that the 'double burden' of disease places on health systems.

    Iwakabe, Shigeru; Gazzola, Nicola

    2009-07-01

    Recent developments in case study methodology reflect a rising interest that clinicians and researchers share in building a clinically useful and empirically sound knowledge base from single-case studies. The present article describes three types of single-case studies (clinical, experimental, systematic) and examines their potential contributions to psychotherapy research. It then lays out three ways in which single-case studies can be aggregated and synthesized to enhance clinical understanding: (a) a case database that allows clinicians to efficiently search for relevant cases, (b) a metasynthesis of single-case studies that integrates common themes across similar cases, and (c) an individual case comparison method in which closely matched cases are compared to identify both therapeutic and hindering processes.

    De Wael, K; Lepot, L; Lunstroot, K; Gason, F

    2016-01-01

    Since 2002, the 1:1 tape lifting technique on murder victims has been introduced in Belgium. Thirty-six murder cases for which a fibre examination was carried out in our laboratory between 2002 and 2012 are reviewed. These cases all involved the collection of microtraces on 39 victims using a 1:1 taping or similar technique, called semi 1:1 taping. The degree of "positive outcomes" for investigative and comparative fibre cases is high. Especially in cases where the modus operandi of suspects had to be verified, the examination of the 1:1 tape lifting led to very useful fibre results. The findings from some of these fibre cases are used to illustrate the advantages, drawbacks and points of interest of the two collection techniques. These are also compared with the zonal taping technique, another microtrace collection technique applied on victims at the crime scene.

    The aim of this study is to provide an overview of the scientific activity of different psychoanalytic schools of thought in terms of the content and production of case studies published on ISI Web of Knowledge. Between March 2013 and November 2013, we contacted all case study authors included in the online archive of psychoanalytic and psychodynamic case studies (www.singlecasearchive.com) to inquire about their psychoanalytic orientation during their work with the patient. The response rate for this study was 45%. It appears that the two oldest psychoanalytic schools, Object-relations psychoanalysis and Ego psychology or "Classical psychoanalysis" dominate the literature of published case studies. However, most authors stated that they feel attached to two or more psychoanalytic schools of thought. This confirms that the theoretical pluralism in psychoanalysis stretches to the field of single case studies. The single case studies of each psychoanalytic school are described separately in terms of methodology, patient, therapist, or treatment features. We conclude that published case studies features are fairly similar across different psychoanalytic schools. The results of this study are not representative of all psychoanalytic schools, as some do not publish their work in ISI ranked journals.

    2005-01-01

    In order to investigate the analgesic effect of needling at "Sitian" points for the nerve root-involved cervical spondylopathy, 68 cases of the nerve root-involved cervical spondylopathy were randomly divided into a treatment group of 46 cases treated by needling at "Sitian" points, and a control group of 22 cases treated by needling at cervical Jiaji points. After 2 therapeutic courses, the therapeutic effects were evaluated by using the visual analogue scale (VAS) and the semeiographic format. The results showed that the markedly effective rate was 78.3% and 54.5%, respectively in the treatment group and the control group, and the difference between the two groups was of significance (P<0.05). It can be concluded that needling at "Sitian" points can bring about a better therapeutic effect on the improvement of clinical symptoms, physical signs and pain than that of the needling at the cervical Jiaji points.

    Ergotamine is a well known pharmacological remedy applied in neurology (treatment of vascular headache) and in obstetrics (abortive remedy, uterus atony). But today it is rarely used, because of new safer anti-migraine medicine (triptanes) which cause fewer side effects. According to obstetrical indications ergotamine is applied only in hospital treatment. For that reason, cases of intoxication by this class of drugs are rarely observed. Ergotamine causes constriction of the blood vessels through the blockade of alpha-receptors and stimulation of the serotonin-receptors on the walls of blood vessels both in the central nervous system and in peripheral circulation. Intoxication/overdose symptoms may appear on application of therapeutic dose by sensitive patients, mostly by patients with migraine headache using ergotamine preparation for relief of migraine attacks. In the Regional Centre of Clinical Toxicology, a 21-year-old patient was hospitalized. She took about 20 tablets of Cafergot (complex preparation containing 1mg ergotamine tartare and 100mg caffeine). During her stay on the ward, typical symptoms of severe poisoning were observed: nausea, severe vomiting, dizziness, decreased blood pressure without perceptible pulse, narrowing of the blood vessels in the extremities of the body (peripheral vasoconstriction) - paresthesia, digital cyanosis, refrigeration of legs, angina. Due to taking once of a great dose of the drug by the patient, violent process of intoxication, possibility of dangerous complication and also the unavailability of specific antidotes and lack of efficient methods of extracorporeal elimination of the drug, the patient was intensively controlled and symptomatic treatments according to the law of intensive therapy was applied.

    Full Text Available Risk management is a decision-making process involving considerations of political, social, economic and engineering factors with relevant risk assessments relating to a potential hazard. In the last decade, a number of risk management tools are introduced and employed to manage and minimize the uncertainty and threats realization to the organizations. However, the focus of these methodologies are different; in which companies need to adopt various risk management principles to visualize a full picture of the organizational risk level. Regarding to this, this paper presents a new approach of risk management that integrates Hierarchical Holographic Modeling (HHM, Enterprise Risk Management (ERM and Business Recovery Planning (BCP for identifying and assessing risks as well as managing the consequences of realized residual risks. To illustrate the procedures of the proposed methodology, a logistic company ABC Limited is chosen to serve as a case study Through applying HHM and ERM to investigate and assess the risk, ABC Limited can be better evaluated the potential risks and then took the responsive actions (e.g. BCP to handle the risks and crisis in near future.

    From 1994 to 2013, French forensic entomology laboratories investigated 1,093 cases. Larder beetles (Coleoptera: Dermestidae) were observed in 81 (7.5%) of these cases. To describe and analyze these 81 cases, eight parameters were used: city, location (indoor or outdoor), decay stage (fresh, decay, or dry), dermestid species and instar (adults and/or larvae), presence of living calliphorid larvae, presence of calliphorid pupae or adults, and presence of other necrophagous species. Eight Dermestidae species were observed: Dermestes frischii (42% of cases), Dermestes undulatus (35.8%), Dermestes peruvianus (12.3%), Dermestes lardarius (9.9%), Dermestes haemorrhoidalis (8.6%), Dermestes maculatus (7.4%), Dermestes bicolor (3.7%), and Dermestes ater (1.2%). Larder beetles primarily developed on human cadavers in outdoor locations in areas with a dry climate and were never reported in oceanic areas (which are characterized by frequent rainfall and high ambient humidity). The number of dermestid species on a single corpse never exceeded three. Typically, one species was found per corpse. Species differed between indoor and outdoor cases, with D. frischii and D. undulatus dominant in outdoor cases, while D. peruvianus dominant in indoor cases. Calliphoridae was found in 88% of the cases, while Hydrotaea and Piophilidae were observed 40% of the time. Regarding Coleoptera, Necrobia spp. (Coleoptera: Cleridae) was observed in 46% of the cases. Lastly, we observed a typical decomposition pattern, with preferential feeding areas on the face, hands, and feet (i.e., the extremities). Pupation chambers on or inside the bones were not observed.

    This retrospective case study examined reports (N=27) of medication errors made by nursing students involving tubing and catheter misconnections. Characteristics of misconnection errors included attributes of events recorded on MEDMARX error reports of the United States Pharmacopeia. Two near miss errors or Category B errors (medication error occurred, did not reach patient) were identified, with 21 Category C medication errors (occurred, with no resulting patient harm), and four Category D errors (need for increased patient monitoring, no patient harm) reported. Reported intravenous tubing errors were more frequent than other type of tubing errors and problems with clamps were present in 12 error reports. Registered nurses discovered most of the errors; some were implicated in the mistakes along with the students.

    2013-10-01

    Full Text Available This paper describes the potential suitability of case study methodology for inquiry with the homeless population. It references a research study that uses case study research method to build theory. This study's topic is the lived experience of destitute individuals who reside in homeless shelters, and explores the homeless shelter built environment's potential influence on resident satisfaction and recovery. Case study methodology may be appropriate because it explores real-life contextual issues that characterize homelessness and can also accommodate the wide range of homeless person demographics that make this group difficult to study in a generalized fashion. Further, case study method accommodates the need within research in this area to understand individualized treatments as a potential solution for homelessness.

    Full Text Available Since 1997, Critical Chain Project Management (CCPM method has received a lot of attention and hundreds of successful cases have also been reported and all claims that it is possible to rapidly achieve highly reliable on-time delivery (OTD with short project lead time (PLT in multi-project environment. The main reason that CCPM can achieve highly reliable OTD and short PLT in multi-project environment can be contributed to that CCPM makes good use of safety time imbedded in tasks by two changes: logistical change and bad human behaviors change. However, if no bad human behaviors involved, does the mere emphasis on logistical change contributed to the success of project time reduction and OTD improvement? This is the key question still remained. A comparative study of the critical chain and Program Evaluation and Review Technique (PERT planning methods, no bad human behaviors involved, was performed in this study. The simulation results showed that in terms of mean project time, CCPM is no significantly better than PERT. However, in terms of plan reliability, CCPM achieve higher reliable than PERT did and this is the contribution of CCPM logistical change.

    This paper discusses the use of bioremediation as an effective method to clean up diesel-range hydrocarbon spills in northern latitudes. The results of a laboratory study of microbial degradation of hydrocarbons under simulated arctic conditions showed that bioremediation can be effective in cold climates and led to the implementation of a large-scale field program. The results of 3 years of field testing have led to a significant reduction in diesel-range hydrocarbon concentrations in the contaminated area.

    2015-01-01

    Full Text Available Erdheim Chester disease (ECD is a rare non-Langerhans cell histiocytosis, commonly involving the musculoskeletal system. Other tissue can also be involved, including the central nervous system with wide spectrum of clinical features, at times being nonspecific. This can cause diagnostic dilemmas with delay in diagnosis and initiation of therapy. Here we describe a 63-year-old man who had presented with ataxia and behavioral changes, bony pains, weight loss, and fatigue. His computed tomography (CT, 99Tc scintigraphy and histopathological features on bone biopsy were consistent with ECD. Thus, ECD should be considered as a differential diagnosis in patients presenting with bony pain and nonspecific features of multiorgan involvement.

    Full Text Available This research reviews the literature on case study as a strategic qualitative research methodology. Although case studies have been criticised by some authors as lacking scientific rigour and do not address generalizability, this research, however, reiterated its appropriateness when dealing with a process or a complex real-life activities in great-depth. Case study has been commonly used in social science fields like sociology, industrial relations and anthropology eventhough generally was considered an underutilized strategy. Hence, this research explained the general concept of a case study, strengths and weaknesses of using this method knowing that theoretically case is exciting and data rich. Based on a study of four organizations and the researcher’s own experience, this article described matters on how case study was undertaken, gaining excess to those organizations and the systematic process of data collection and triangulation (multiple techniques. It was noted that combining multiple techniques for elicitng data in case study research actually strengthens and confirmed results.

  7. Selection of controls in case-control studies. I. Principles.

    Science.gov (United States)

    Wacholder, S; McLaughlin, J K; Silverman, D T; Mandel, J S

    1992-05-01

    A synthesis of classical and recent thinking on the issues involved in selecting controls for case-control studies is presented in this and two companion papers (S. Wacholder et al. Am J Epidemiol 1992;135:1029-50). In this paper, a theoretical framework for selecting controls in case-control studies is developed. Three principles of comparability are described: 1) study base, that all comparisons be made within the study base; 2) deconfounding, that comparisons of the effects of the levels of exposure on disease risk not be distorted by the effects of other factors; and 3) comparable accuracy, that any errors in measurement of exposure be nondifferential between cases and controls. These principles, if adhered to in a study, can reduce selection, confounding, and information bias, respectively. The principles, however, are constrained by an additional efficiency principle regarding resources and time. Most problems and controversies in control selection reflect trade-offs among these four principles.

    2009-12-01

    Full Text Available Although Information Systems' literature contains more ERP success cases, it is not rare to notice unsuccessful ERP deployments that extend over years and consume much more financial and human resources than expected. One of the reasons for that is related to the fact that ERP implementation is a social-technical multifaceted and complex process. The key success factors for ERP deployment comprises varied features such as strategic planning, project management, consulting team performance, user involvement, and top management support. This paper intends to investigate an ERP deployment case that is considered unsuccessful due to the low level of user satisfaction. The ERP's key success factors presented in literature were compared to the characteristics of this actual ERP implementation. The case study was performed in a medium-size aluminium and copper recycling industry located in the Belo Horizonte metropolitan area, the capital of Minas Gerais state, in Brazil. The research results provided evidence that the unsuccessful ERP project was partially generated by the insufficient presence of critical success factors suggested in the ERP literature. Embora a literatura contenha mais casos de sucesso de ERP, não é raro constatar implantações mal sucedidas que se estendem por vários anos e consomem muito mais recursos humanos e financeiros do que o esperado. Um dos motivos pelos quais isso ocorre é o fato de que a implantação de um ERP é um processo sócio-técnico complexo e multifacetado. Os fatores-chave de sucesso na implantação de sistemas ERP contemplam variados aspectos tais como planejamento estratégico, gerência do projeto, atuação da equipe de consultoria externa, envolvimento de usuários, apoio da alta administração, entre outros. O presente trabalho se propõe a investigar uma implantação de ERP percebida como razoavelmente mal sucedida em função do baixo grau de satisfação dos seus usuários. Os fatores-chave de

    Full Text Available Modern educational technologies are based on competence approach and focus on the future professional activity. Case study is one of the most significant technologies in modern higher education. The basic concepts used in the case study method are a “situation” and an “analysis”, as well as their derivative - “analysis of the situation”. The case study method of is one of the best tools for gaining experience, as it investigates practical situations that occur in managerial job. It combines theoretical knowledge with the analysis of the actual practical experience in accordance with a major. Doing case studies students read the description of the situation and offer divergent projects of managerial decisions that could be used by real managers dealing with the problem posed by the case study author. Answers to the questions posed in the case description are not given, as a rule, since the main purpose in the case analysis is to organize a discussion in the classroom or provoke speculations of those who do the self-study.

    2016-01-01

    In case of gunshot deaths, atypical wounds can make the distinction between entrance and exit wounds harder. They may be due either to anatomical reasons or to diverse cogent ballistic arguments. The reported case pertains to a fatal hunting accident involving an expanded conical point bullet against the neck with both atypical entrance and exit wounds. Ballistic analyses including test firings allowed a better understanding of the external and internal findings. Upon premature impact with an intermediary target, the bullet experienced expansion in the formation of sharp brass petals responsible for a star-shaped entry wound. The trajectory of the deformed high energy projectile through the victim's body was then deviated by the cervical column, causing it to be tangential to the skin when exiting the body. The description of such atypical cases may benefit other experts and may assist in their investigation into similar cases.

    Full Text Available Fluid collections are common findings of pancreatitis and spread, more often, along preferential drainage pathways in the abdomen. In some rare cases, fluid collections may spread towards extra-abdominal sites like the mediastinum leading to the formation of mediastinal collections. We present the case of a 52-years-old man with pain in the right upper quadrant of the abdomen and mid-epigastrium lasting for some hours. Laboratory tests suggested a diagnosis of pancreatitis. CT and subsequent MRI revealed changes consistent with acute exacerbation on chronic pancreatitis spreading to the mediastinum and to the greater omentum.

    A case of osseous tuberculosis has been presented in a young black man who was known to be an addict to cocaine. An osteolytic lesion involved the proximal end of the tibia, being eccentric and subarticular in location. The knee joint spaces were intact, suggesting that no obvious involvement of the cartilages was present. Thus, neoplastic lesions such as chondroblastoma and giant cell tumor were considered in the differential diagnosis of the lesion which appeared to be benign radiologically. The lesion proved to be tuberculous in nature, with intact knee joint cartilages. A diagnosis of tuberculous 'pseudotumor' might be used aptly. (orig./SHA).

    The ocular system can be affected in systemic lupus erythematosus (SLE) in one third of patients. However, optic nerve involvement is relatively uncommon, but is more so in pediatric SLE patients, where it can occur in 1% of cases. We report three children with SLE who presented with optic nerve involvement. Two children had optic neuritis, with optic neuritis being the first manifestation in one child. The third child had ischaemic optic neuropathy secondary to antiphospholipid syndrome. A careful work up for SLE should be performed in every child with optic nerve disease. Prompt diagnosis and early treatment results in a better prognosis.

    Full text: A forty-two-year-old male presented to the Royal Adelaide Hospital with symptoms of increasing shortness of breath, swelling in both ankles, petechial rash and blood in his sputum. Initial investigations showed cardiomegaly, right ventricular hypertrophy, patchy lung infiltrates, a platelet count of 1500 and a clotting time of 60 seconds. A V/Q scan indicated a high probability of pulmonary embolism. Further investigations showed that the patient was positive for lupus anticoagulant and cardiolipin antibodies. A diagnosis of primary antiphospholipid syndrome was made. The patient``s high risk of strokes and hemorrhaging prompted investigation by a {sup 99}mTc-HMPAO brain scan. Further V/Q scans were performed to follow up the initial finding of multiple pulmonary embolism and a R-L shunt study was performed to investigate a left subclavian murmur. The patient was admitted for four weeks and began treatment which included cyclaphosphamide, corticosteroids and plasmaphoresis and was discharged when stable. Over the next six months he was re admitted three times for relapse of antiphospholipid syndrome. On his fourth admission he collapsed and died five hours after admission. Cause of death was due to cardiac arrhythmia secondary to severe right ventricular hypertrophy and dilation. The effects of antiphospholipid syndrome was believed to be responsible for this outcome.

    Full Text Available This India is the Fifth largest producer of Electricalenergy in the world. Despite such achievements the gapbetween demand and supply of electrical energy is increasingevery year and power sector is highly capital – intensive. Thusthe deficit in installed capacity was nearly 10000MWper year.So the gap between demand and supply is continuouslyincreasing day by day. An energy audit is a study of a plant orfacility to determine how and where energy is used and toidentify methods for energy savings. The opportunities lie inthe use of existing renewable energy technologies, greaterefforts at energy efficiency and the dissemination of thesetechnologies and options. This thesis provides an overview of ageneral energy conservation measures (ECMs that can becommonly recommended for NIT Hamirpur. It should be notedthat the Energy auidut presented in this paper does not pretendto be exhaustive nor comprehensive. It provides merely toindicate some of the options that energy auditor can considerwhen performing an analysis of this institute. Energyconservation and exploration of new energy avenues are thewell accepted solution to fulfil the demand in future. The totalcost of energy plays a vital role in determining the product costof a commodity. Therefore the identification of potential energysavings and implementation for a given institutional facility isunimportant to ensure its competitive advantage over otherinstitute. This paper work presents such energy saving methodsin a methodological approach, experienced during a detailedenergy audit of NIT Hamirpur.

    Ameloblastic Carcinoma (AC) is uncommon malignant epithelial odontogenic tumour of jaw, with characteristic histologic features and behavior. Clinically, it has aggressive, infiltrative growth pattern with a distinct predilection for mandible. It exhibits histologic features of ameloblastoma and gets dedifferentiated overtime to culminate in carcinoma. Majority of the cases arise denovo (primary) and only few cases arise from a pre-existing ameloblastoma (secondary). Spindle-cell differentiation in ameloblastic carcinoma is rare; Salter described it as a separate entity “low-grade spindle cell ameloblastic carcinoma. Here we report a case of 32-year-old female patient who presented with a swelling present for past six months. It was diagnosed as Spindle cell Ameloblastic Carcinoma (SpAC), after the hemimandibulectomy the patient was under regular follow up for 14 months, no sign of recurrence was seen. PMID:28274070

Computed tomography revealed a soft tissue density mass replacing the left renal pelvis, which was suspicious for renal pelvic cancer, and the diagnosis of idiopathic RPF was surgically confirmed. To the best of our knowledge, a few cases of idiopathic RPF presenting with features of a localized unilateral renal pelvic mass mimicking renal pelvic cancer have been reported.

    2010-04-01

    The association between memories of the terrorist explosion at the Dolphinarium discotheque in Tel Aviv and the level of personal involvement in the explosion was investigated. Memories of injured victims, uninjured eyewitnesses, and uninvolved controls who learned about the explosion from the mass media were compared. It was expected that memory of the explosion would be most and least detailed and accurate among the victims and the controls, respectively. The participants responded to an open-ended question about the explosion, as well as to specific and multiple-choice questions. Data analyses showed that the victims and the eyewitnesses remembered more details than the controls, and that the victims remembered both central and peripheral details more accurately than the other participants. Degree of involvement in the same traumatic experience was thus shown to be differentially associated with memory accuracy.

  15. Towards More Case Study Research in Entrepreneurship

    Directory of Open Access Journals (Sweden)

    2012-03-01

    Full Text Available Entrepreneurship as an emerging discipline has made good strides, but according to some, has fallen short of bringing its theory and literature up to the standards of others in the management sciences. Rich with the descriptive detail needed for insightful theory building in entrepreneurship, scholars have called for more case study research, particularly those incorporating non-retrospective and longitudinal observations. At the same time however, it has become rare to find such research published in A-level journals dedicated to entrepreneurship. A survey presented here of major entrepreneurship journals over the past six years revealed a publication rate of only 3% using the case study method. This presents a major impediment for developing fresh research in this field based upon the study of real cases. The author explores how the case study method has been applied to entrepreneurship research and provides recommendations for improved publication rates.

  16. Safety cases for medical devices and health information technology: involving health-care organisations in the assurance of safety.

    2013-09-01

    In the United Kingdom, there are more than 9000 reports of adverse events involving medical devices annually. The regulatory processes in Europe and in the United States have been challenged as to their ability to protect patients effectively from unreasonable risk and harm. Two of the major shortcomings of current practice include the lack of transparency in the safety certification process and the lack of involvement of service providers. We reviewed recent international standardisation activities in this area, and we reviewed regulatory practices in other safety-critical industries. The review showed that the use of safety cases is an accepted practice in UK safety-critical industries, but at present, there is little awareness of this concept in health care. Safety cases have the potential to provide greater transparency and confidence in safety certification and to act as a communication tool between manufacturers, service providers, regulators and patients.

    We evaluated the efficiency of botulinum toxin type A injection followed by a rehabilitation program including individual therapy, group therapy, and occupational therapy in cases of cerebral palsy with upper extremity involvement. A total of 29 injections were performed on 25 patients, and the patients were placed on rehabilitation program. At 3-month and 6-month assessments, there was a significant improvement in lateral grip strength, 9 Hole Peg test, Upper Limb Physician's Rating Scale and pediatric functional independence measure total scores. There were significant decreases in active range of motion in elbow extension, supination, and wrist extension, and Modified Ashworth Scale in elbow flexion, elbow pronation, and wrist flexion at 6-week, 3-month, and 6-month assessments. Combination of group therapy with traditional therapy methods after injection is effective in cases of cerebral palsy with upper extremity involvement.

    Studies on vasculitis in black Africa are rare. The purpose of this report is to describe a retrospective study of systemic vasculitis managed in the internal medicine, ORL and cardiolology departments of the Aristide le Dantec University Hospital in Dakar, Senegal from 1995 to 2007. A series of 27 cases involving 7 men and 20 women with a mean age of 49 years was compiled. Primary vasculitis included Horton disease in 3 cases, Wegener disease in 2, Takayasu disease in 1, and Buerger disease in 1. Secondary vasculitis included mixed cryoglobulinemia with Gougerot Sjögren syndrome in 7 cases, primary Goujeröt syndrome in 4, rheumatoid arthritis in 3, nodosa periarteritis with hepatitis B in 2, SHARP syndrome in 1, and polymyositis in 1. The remaining two cases involved abdominal periaortitis including one associated with retrosperitoneal fibrosis and tuberculosis and the other with spondylarthropathy. Corticotherapy in combination with anticoagulants, immunosuppressive therapy, and surgery, when necessary, allowed effective management in 24 cases. The findings of this study show that systemic vasculitis can have numerous etiologies and indicate that secondary forms are the most common. Appropriate care modalities are needed to prevent severe outcome in Senegalese hospitals.

    Horner syndrome, in which ptosis, miosis, and anhidrosis occur concomitantly, can arise from injury to the sympathetic nerve pathways anywhere from the brain to the end organs. Incomplete Horner syndrome lacks the sign of anhidrosis. We present a case of incomplete Horner syndrome caused by internal carotid artery dissection and provide a road map of the cervical sympathetic nerves involved in Horner syndrome to explain its etiology. We also discuss the imaging of and therapy for internal carotid artery dissections.

    Full Text Available Background: Limited data available about the mechanisms of dysphagia and areas involving swallow after brain damage; accordingly it is hard to predict which cases are more likely to develop swallowing dysfunction based on the neuroimaging. The aim of this study was to investigate the relationship between brain lesions and dysphagia in a sample of acute conscious stroke patients.Materials and Methods: In a cross-sectional study, 113 acute conscious stroke patients (69 male mean [standard deviation (SD] age 64.37 [15.1], participated in this study. Two neurologists and one radiologist localized brain lesions according to neuroimaging of the patients. Swallowing functions were assessed clinically by an expert speech pathologist with the Mann Assessment of Swallowing Ability (MASA. The association of brain region and swallowing problem was statistically evaluated using Chi-square test. Results: Mean (SD MASA score for the dysphagic patients was 139.61 (29.77. Swallowing problem was significantly more prevalent in the right primary sensory (P = 0.03, right insula (P = 0.005, and right internal capsule (P = 0.05. Conclusion: It may be concluded from these findings that the right hemisphere lesions associated with occurring dysphagia. Further studies using more advanced diagnostic tools on big samples particularly in a perspective structure are needed.

    2015-06-01

    Full Text Available Collecting duct carcinoma (CDC is a rare and aggressive form of renal cell carcinoma (RCC arising from the principal cells of the collecting duct.  One third of cases present with metastatic disease, but many present in a manner similar to conventional RCC or urothelial carcinoma (UC.  We discuss a case of CDC which presented as a small mass at the cortico-medullary junction, and was discovered at robotic partial nephrectomy (RPN to be grossly involving the collecting system. A 62-year-old man presented with a small renal mass suspicious for RCC, which was found on computed tomography (CT after an episode of gross hematuria.  After thorough workup, RPN was attempted; however, intraoperatively the mass was found to be involving the collecting system.  Radical nephroureterectomy was performed, and the pathology report revealed CDC.  CDC is a rare and aggressive form of RCC.  While many cases are metastatic at diagnosis, most patients present with the incidental finding of a small renal mass.  There are no reports of a CDC involving the collecting system at RPN after negative ureteroscopy preoperatively.  The adjuvant therapeutic options for CDC are limited, and long term survival is poor.

    2015-06-01

    A congenital bony defect of the external auditory canal (EAC) may cause temporomandibular joint (TMJ) herniation into the EAC. This rare condition is known as persistent foramen tympanicum. We report 2 cases of symptomatic TMJ herniation through a patent foramen tympanicum. The patients complained of mastication-induced tinnitus. Otoscopic examination revealed that a whitish protruding mass at the anterior wall of the EAC bulged when the patients closed their mouths. After conservative managements such as avoidance of chewing foods on the affected side for 2 months, mastication-induced tinnitus disappeared and the size of protruding mass was decreased in one of the patients. Surgical repair of the bony defect has been the treatment of choice. In cases when symptoms are trivial and patients do not want surgical treatment, however, conservative management would be a sound alternative.

    2016-01-01

    Solitary fibrous tumor (SFT) is a rare neoplasia of mesenchymal origin, initially described in visceral pleura and lately discovered to have ubiquitous distribution. SFT of the urogenital tract is uncommon and appears to have similar morphologic features and biologic behaviors as SFTs found elsewhere. We present two new cases of SFT of the bladder and review 22 similar cases published in the literature. Due to the general indolent behavior of these lesions, a complete but organ sparing surgical excision should be considered when technically feasible. Therefore, proper identification and characterization of SFT through morphological and immunohistochemical criteria on biopsy specimens are mandatory in the differential diagnosis from other more aggressive spindle-cell tumors, thus avoiding unnecessary radical surgery.

    2010-05-01

    Non-contrast post-mortem computed tomography (pm-CT) is useful in the evaluation of bony pathologies, whereas minimally invasive pm-CT-angiography allows for the detection of subtle vascular lesions. We present a case of an accidentally self-inflicted fatal bullet wound to the chest where pm-CT-angiography revealed a small laceration of the anterior interventricular branch of the left coronary artery and a tiny disruption of the right ventricle with pericardial and pleural effusion. Subsequent autopsy confirmed our radiological findings. Post-mortem CT-angiography has a great potential for the detection of vascular lesions and can be considered equivalent to autopsy for selected cases in forensic medicine.

    For several decades, Morocco is confronted to medico-social problem of scorpion stings and envenomations. In 2009, epidemiological data established by the Poison Control Center recorded 29,816 stung patients, with an incidence of 1.1‰ and a fatality rate of 0.18%. The neurotoxins from scorpion venom are potent activators of the autonomic nervous system resulting a physiopathological disorder of vital systems. The most serious clinical manifestations are neurotoxic effects, pulmonary edema and cardiovascular distress. This present work reports the cases of three children (4 years and 6 months, 8 months and 15 days, 4 years), hospitalized in intensive care for an envenomation by Androctonus mauritanicus (the most fatal scorpion specie). The children presented cardiac dysfunction where pulmonary edema and state of shock were complications resultants. Two cases survived after supportive and symptomatic treatment based on dobutamine as primordial treatment in cardiovascular and pulmonary correction and other drugs. The third case died. The objective of this work was to detect the limit of the effectiveness of symptomatic treatment during a severe scorpion envenomation.

  14. Recurrent malignant otitis externa with multiple cranial nerve involvement: A case report

    Directory of Open Access Journals (Sweden)

    Đerić Dragoslava

    2016-01-01

    Full Text Available Introduction. Necrotizing otitis externa is a rare but conditionally fatal infection of external auditory canal with extension to deep soft tissue and bones, resulting in necrosis and osteomyelitis of the temporal bone and scull base. This condition is also known as malignant otitis due to an aggressive behavior and poor treatment response. Early diagnosis of malignant otitis is a difficult challenge. We present an illustrative case of necrotizing otitis externa and suggest some strategies to avoid diagnostic and treatment pitfalls. Case Outline. A 70-year-old patient presented with signs of malignant otitis externa, complicated by peripheral facial palsy. Adequate diagnostic and treatment procedures were performed with clinical signs of resolution. The recurrence of malignant infection had presented three months after previous infection with multiple cranial nerve neuropathies and signs of jugular vein and lateral sinus thrombosis. An aggressive antibiotic treatment and surgery were carried out, followed by substantial recovery of the patient and complete restoration of cranial nerves’ functions. Conclusion. Necrotizing otitis externa is a serious condition with uncertain prognosis. The suspicion of malignant external otitis should be raised in cases of resistance to topical treatment, especially in patient with predisposing factors. Evidence-based guideline for necrotizing otitis externa still doesn’t exist and treatment protocol should be adjusted to individual presentation of each patient.

    2015-01-01

    Several approaches to clinical ethics consultation (CEC) exist in medical practice and are widely discussed in the clinical ethics literature; different models of CECs are classified according to their methods, goals, and consultant's attitude. Although the "facilitation" model has been endorsed by the American Society for Bioethics and Humanities (ASBH) and is described in an influential manual, alternative approaches, such as advocacy, moral expertise, mediation, and engagement are practiced and defended in the clinical ethics field. Our Clinical Ethics Center in Paris was founded in 2002 in the wake of the Patients' Rights Act, and to date it is the largest center that provides consultation services in France. In this article we shall describe and defend our own approach to clinical ethics consultation, which we call the "Commitment Model," in comparison with other existing models. Indeed commitment implies, among other meanings, continuity through time, a series of coherent actions, and the realization of important social goals. By drawing on a recent consultation case, we shall describe the main steps of our consultation procedure: interviews with major stakeholders, including patients and proxies; case conferences; and follow up. We shall show why we have chosen the term "commitment" to represent our approach at three different but interrelated levels: commitment towards patients, within the case conference group, and towards society as a whole.

    Full Text Available Background: Diphtheria is still a fatal disease even in the era of universal immunization. Diphtheria myocarditis, one of the serious complications of respiratory diphtheria may cause death if not recognized and treated properly. Aims and Objectives: To determine the outcomes of cardiac involvement in respiratory diphtheria. Materials and Methods: One hundred (n = 100 patients with respiratory tract diphtheria were evaluated in respect to cardiac involvement. All patients were closely monitored for a minimum period of 4-6 weeks from the onset of respiratory symptoms. Continuous ECG monitoring including blood biochemistry (SGOT, CPK-MB, and Troponin-T were done in each case. Results : The most common symptoms were throat pain seen in 94 cases, palpitation in 56 cases, bull neck in 40 cases, shortness of breath in 12 cases, fever in 9 cases, and nasal regurgitation in 8 cases. Most common complication observed was myocarditis seen in 70 patients and majority of patients (60 were asymptomatic. The ECG changes were T wave inversion in 54 patients, inappropriate sinus tachycardia in 38 patients, ST segment depression in precordial leads in 8 patients, Mobitz type II block in 6 patients, Mobitz type I block in 4 patients, RBBB in 4 patients, multiple atrial ectopics in 4 patients, and sinus bradycardia in 2 patients. A total number of five patients died. Conclusions: Myocarditis was commonest and serious complication of respiratory diphtheria. Increase in vaccination coverage and improvement of socioeconomic status are all effective preventive measures to reduce the incidence of diphtheria.

    Full Text Available Four cases of serious cardiac attacks by autochthonous Trypanosoma cruzi infection from the Brazilian Amazon are reported; three of them occurred in micro-epidemic episodes. The manifestations included sudden fever, myalgia, dyspnea and signs of heart failure. Diagnosis was confirmed by specific exams, especially QBC (Quantitative Buffy Coat and natural xenodiagnosis. Despite treatment with benznidazol, three patients died with serious myocarditis, renal failure and cardiac tamponade. The authors call attention to the emergence of this disease and reveal a previously unknown pathogenicity of T. cruzi strains in this area, added to a non-usual transmission form.

    A case of an 87-year-old woman with a history of Graves disease presenting with a 5-year history of severe ptosis and very poor levator function of the left side is presented. MRI revealed marked enlargement of all extraocular muscles and significant enlargement of the left levator muscle. Given the patient's age and atypical presentation of thyroid eye disease (TED), she was taken to the operating room for biopsy and ptosis repair with frontalis suspension. Histopathological analysis revealed chronic inflammation and fibrosis consistent with Graves disease.

    Full Text Available Extra-abdominal fibromatosis is a benign fibrous neoplasm of locally aggressive behavior. Surgical excision with a wide margin is the treatment of choice. The aim of the present work is to report the case of fibromatosis in an 11-year-old melanodermic patient, who showed swelling in the area of the right mandible. Conservative surgery was performed based on the initial histopathological diagnosis of benign lesion suggestive of neural origin. The new anatomopathological examination of the surgical specimen was compatible with fibromatosis. The patient is still under periodic observation as part of the five-year surgical follow-up, showing no signs of recurrence.

    Full Text Available Swyer syndrome is caused by abnormal sex differentiation during the embryonic period, resulting in incomplete intrauterine masculinization and undifferentiated gonads. The current case report describes a patient with Swyer syndrome associated with stage 3 gonadal dysgerminoma who has survived for 23 years. At age 18, this patient sought assistance for primary amenorrhea from the Gynecological Services Department of the University of Brasília Hospital. A physical examination revealed that the patient was at Tanner stage 4 with respect to axillary hair, breasts, and pubic hair; she presented with a eutrophic vagina and a small cervix. She was treated with a combination of estrogens and progestogens to induce cycling. Approximately 4 years later, a complex tumor was found and resected; a histopathological analysis revealed that this tumor was a right adnexal dysgerminoma with peritoneal affection. The patient was also subjected to chemotherapy. Her follow-up has continued to the present time, with no signs of tumor recurrence. In conclusion, this report describes an extremely rare case in which Swyer syndrome was associated with ovarian dysgerminoma; relative to similar patients, the described patient has survived for an unusually prolonged time.

    Extrahepatic biliary atresia (EHBA) is a rare disease characterized by progressive and obliterative cholangiopathy in infants and is one of the major causes of secondary vitamin K deficiency bleeding (VKDB) due to cholestasis-induced fat malabsorption. Breast feeding increases the tendency of bleeding in EHBA patients because breast milk contains low amounts of vitamin K. A 2-month-old female infant unexpectedly died, with symptoms of vomiting and jaundice prior to death. She had been born by uncomplicated vaginal delivery and exhibited normal growth and development with breastfeeding. There was no history of trauma. She received vitamin K prophylaxis orally. In an emergency hospital, a CT scan showed a right intracranial hematoma and mass effect with midline shift to the left. In the postmortem examination, severe atresia was observed in the whole extrahepatic bile duct. Histologically, cholestasis, periductal fibrosis, and distorted bile ductules were noted. The gallbladder was not identified. A subdural hematoma and cerebellar tonsillar herniation were found; however, no traumatic injury in any part of the body was observed. Together, these findings suggest that the subdural hemorrhage was caused by secondary vitamin K deficiency resulting from a combination of cholestasis-induced fat malabsorption and breastfeeding. Subdural hemorrhage by secondary VKDB sometimes occurs even when vitamin K prophylaxis is continued. This case demonstrated that intrinsic factors, such as secondary VKDB (e.g., EHBA, neonatal hepatitis, chronic diarrhea), should also be considered in infant autopsy cases presenting with subdural hemorrhage.

    Full Text Available Abstract Introduction Intracranial schwannomas unrelated to the cranial nerves are uncommon. We report a new case of tentorial schwannoma unrelated to the cranial nerves, with extension into the pons. A literature review with discussion of the most relevant pathogenetic aspects is also performed. Case presentation A 42-year-old Caucasian man was admitted with right-sided paresthesias and weakness of his upper and lower extremities. The neurological examination revealed right hemiparesis and hemi-hypoesthesia. A brain magnetic resonance imaging scan revealed a cerebellopontine lesion, arising from the left free edge of the tentorium, and extending into his pons. A piecemeal removal was performed through a retrosigmoid approach. The lesion was not found to be associated with any cranial nerves. The histological examination revealed a schwannoma Antoni type A. His postoperative course was uneventful. At one year follow-up, the patient was neurologically intact and the magnetic resonance imaging of his brain performed at that time showed complete removal without signs of recurrence. Conclusion Tentorial schwannomas are rare clinical entities. Knowledge of their clinical, radiological and anatomical characteristics is very important for the correct diagnosis and management.

    We present the first case study of idiopathic gigantic suprapubic lymphedema and buried penis treated with puboscrotal reconstruction in a patient with initial extreme obesity after an extensive weight reduction (120 kg). Massive localized lymphedema of the suprapubic region should be differentiated from the scrotal type. Severe lymphedema could not resolve on its own and weight reduction does not seem to be helpful in such cases. PMID:27574599

    1984-01-01

    The vitreous of three patients with asteroïd hyalosis (average age: 57 years) was obtained by a two-hand closed pars plana vitrectomy. Asteroïd hyalosis was associated with alcoholic neuropathy in the first case, long standing retinal detachment in the second case, and diabetes mellitus in the third case. The visual acuity before and after the surgical procedure improved from 1.2/6 to 6/6 in the first case, from light perception to 0.3/6 in the second case, from 0.6/6 to 4.8/6 in the third case. The vitreous was studied by different ultrastructural technics : transmission electron microscopy (T.E.M.) scanning electron microscopy (S.E.M.) and electron diffraction X ray analysis (E.D.A.X.). By S.E.M. the asteroïd bodies appeared as rounded structures with an irregular surface connected to each other by fibrous strands among sodium chloride crystals. No cellular remnants were observed. By T.E.M. the asteroïd bodies were composed of interwinned ribbons of multilaminar membranes with a periodicity (10 to 60 A) characteristic of complex lipids, especially phospholipids. At the edge of the ribbons there were dots and sometimes clumps of opaque material that tended to crack out of the specimen with the heat of the electron beam. T.E.M. study disclosed the irregular disposition of the calcific bodies. By E.D.A.X. the calcific composition of the rounded structures could be determined : calcium and phosphorus were the main elements detectable in asteroïd bodies of all sizes for all three patients. The average calcium counts for the three successive cases were : 18, 30, 43 and for phosphorus : 9, 14, 26. Potassium was found in the first case, and sulfur in the third case.(ABSTRACT TRUNCATED AT 250 WORDS)

    Purpose: To assess retrospectively the clinical outcome in anal cancer patients, with lymph node involvement, treated with split-course radiation therapy and receiving a boost through external beam radiation therapy (EBRT) or brachytherapy (BCT). Methods and Materials: From 2000 to 2005, among 229 patients with invasive nonmetastatic anal squamous cell carcinoma, a selected group of 99 patients, with lymph node involvement, was studied. Tumor staging reported was T1 in 4 patients, T2 in 16 patients, T3 in 49 patients, T4 in 16 patients, and T unknown in 14 patients and as N1 in 67 patients and N2/N3 in 32 patients. Patients underwent a first course of EBRT (mean dose, 45.1 Gy) followed by a boost (mean dose, 18 Gy) using EBRT (50 patients) or BCT (49 patients). All characteristics of patients and tumors were well balanced between the BCT and EBRT groups. Prognostic factors of cumulative rate of local recurrence (CRLR), cumulative rate of distant (including nodal) recurrence (CRDR), colostomy-free survival (CFS) rate, and overall survival (OS) rate were analyzed for the overall population and according to the nodal status classification. Results: The median follow-up was 71.5 months. The 5-year CRLR, CRDR, CFS rate, and OS rate were 21%, 19%, 63%, and 74.4%, respectively. In the overall population, the type of node involvement (N1 vs N2/N3) was the unique independent prognostic factor for CRLR. In N1 patients, by use of multivariate analysis, BCT boost was the unique prognostic factor for CRLR (4% for BCT vs 31% for EBRT; hazard ratio, 0.08; P=.042). No studied factors were significantly associated with CRDR, CFS, and OS. No difference with regard to boost technique and any other factor studied was observed in N2/N3 patients for any kind of recurrence. Conclusion: In anal cancer, even in the case of initial perirectal node invasion, BCT boost is superior to EBRT boost for CRLR, without an influence on OS, suggesting that N1 status should not be a contraindication to

    Full Text Available India experienced very rapid population growth from 48 million to 1.2 billion in a span of decades. In India rapid urbanization, industrialization, population explosion and migration of people in past two decades r esults in enormous growth in the field of road transportation. This resulted in increasing amount of the road traffic leading to increased risk for occurrence of road traffic accidents. In India road traffic injuries will be third leading cause of death by 2020 with the increase in the use of two wheelers and congestion and environmental pollution this mortality rate will continue to rise. Considering the preciousness of human lives, this study has been undertaken to analyse the pattern of injuries in Road Traffic Accidents Involving Two Wheelers to create awareness among the law enforcing authorities, transport authorities and public regarding two wheeler fatalities. A sincere attempt has been made in this study to analyse the distribution of the pattern of injuries sustained by two wheeler travellers, so that appropriate interventional strategies can be evolved at various levels and by different agencies. 147 Two wheeler Accident victims were randomly selected from 1063 road traffic accident cases brought t o the Institute of Forensic Medicine, Madras Medical College Chennai - 3 for routine medico legal examination. Preliminary data were collected from the medico legal documents such as history of the case, Inquest form, First Information Report, Accident Regis ter, Death Report, Clinical data submitted by the investigating officer at the time of medico legal examination. During autopsy, on external exami nation, nature of injury, size, number were measured in all cases. Internal organ injuries were recorded. Caus e of death was arrived at based on the findings made out during autopsy. Totally 147 motorcyclist victims were included in this study in which demographic factors such as age, sex, time of accident, manner of collision

    Science.gov (United States)

    The draft document is intended to be used as part of a process to identify what is known and, more importantly, what is not yet known that could be of value in assessing the broad implications of specific nanomaterials. Like previous case studies (see History/ Chronology below), this draft case study on multiwalled carbon nanotubes (MWCNTs) is based on the comprehensive environmental assessment (CEA) approach, which consists of both a framework and a process. Unlike previous case studies this case study incorporates information about a traditional (i.e., “non-nano-enabled”) product, against which the MWCNT flame-retardant coating applied to upholstery textiles (i.e., the “nano-enabled” product) can be compared. The comparative element serves dual-purposes: 1) to provide a more robust database that facilitates identification of data gaps related to the nano-enabled product and 2) to provide a context for identifying key factors and data gaps for future efforts to evaluate risk-related trade-offs between a nano-enabled and non-nano-enabled product. This draft case study does not represent a completed or even a preliminary assessment of MWCNTs; rather, it uses the CEA framework to structure information from available literature and other resources (e.g., government reports) on the product life cycle, fate and transport processes in various environmental media, exposure-dose characterization, and impacts in human, ecological, and environmental receptors.

    Marfan syndrome is an hereditary condition which primarily affects conjunctive tissue with predominant vascular lesions, aortic insufficiency and aortic dissection which condition vital prognosis. Until further progress is made in the genetic determination of the disease, the diagnosis is currently based on the association of clinical criteria, which enables multidisciplinary management. This approach should lead to specific medical and surgical treatment--which may reduce Marfan morbidity and mortality. We report the case of a 45 year-old patient with suspected Marfan syndrome during adolescence. The presence of a cardiovascular lesion and a recently reported abnormality i.e. a sacral erosion by a dural ectasia, enabled us to confirm the diagnosis. We reviewed the current criteria in Marfan diagnosis and their specific management.

    Objective To analyze cases of violence against transvestites and transsexuals based on their sociodemographic profile. Method Cross-sectional, descriptive research performed in Cajazeiras / Paraíba, consisting of 16 transvestites and transsexuals. Data collection took place in April 2014 and was analyzed descriptively. Results The typology of violence that victimized transvestites and transsexuals were: verbal (91.96%), psychological (58.33%) and physical (33.33%), often between 24 hours and six months preceding the survey. Regarding the spatiality: the street, school and health services were all scenarios of aggression. With respect to the offending agent, the findings point towards neighbors, family members and health professionals. All forms of violence happened between agents and spaces of aggression. Conclusions Violence among this population, silence around the situations of abuse became more pronounced as did its invisibility in the social and institutional context, reflecting the inhibition of human rights and concealment of reality.

    2010-11-01

    We report a case of a midair collision between two F16 fighter aircraft, in which one pilot survived and the other was ejected upon impact and his remains recovered from sea. In autopsy, no patholgy was detected, other than the expected evidence of mechanical trauma. No defects in the aircraft or faults in the parachute or ejection mechanism were found. Reconstruction of the shattered skull base and the cervical vertebrae revealed fusion of the atlanto-occipital joint (occipitalization) and a left paracondylar process. The effective diameter of the spinal canal was decreased by the abnormal articulation. Such malformations can cause a wide range of neurologic deficits. Considering the skill and alertness needed to operate a supersonic fighter aircraft, with the pressure applied by the heavy protective head gear and various G forces endured by the spinal column during flight, we postulate that the collision was related to the pilot's sudden incapacitation.

    Clobazam is a benzodiazepine with anti-anxiety and anticonvulsant properties marketed in several countries. Norclobazam, a metabolite of clobazam, has similar pharmacological activity but weaker sedative and tranquilizing effect. The two drugs were detected by GC-MS and determined by HPLC-DAD in the samples from a postmortem case. The femoral blood concentrations of clobazam and norclobazam were 0.72 and 36 μg/mL, respectively. The concentration of the active norclobazam was very high. The sum of both clobazam and norclobazam blood concentration (36.72 μg/mL) was clearly toxic, but was not necessarily fatal. Other associated drugs concentrations were within their therapeutic ranges. Interactions due to drug association were discussed.

    2008-09-01

    Full Text Available The purpose of this retrospective study was to analyze the cases of traumatic dental injuries involving root fracture and/or periodontal ligament injury (except avulsion treated at the Discipline of Integrated Clinic, School of Dentistry of Araçatuba, São Paulo State University (UNESP, Brazil, from January 1992 to December 2002. Clinical and radiographic records from 161 patients with 287 traumatized teeth that had sustained root fracture and/or injuries to the periodontal ligament were examined. The results of this survey revealed that subluxation (25.09% was the most common type of periodontal ligament injury, followed by extrusive luxation (19.86%. There was a predominance of young male patients and most of them did not present systemic alterations. Among the etiologic factors, the most frequent causes were falls and bicycle accidents. Injuries on extraoral soft tissues were mostly laceration and abrasion, while gingival and lip mucosa lacerations prevailed on intraoral soft tissues injuries. Radiographically, the most common finding was an increase of the periodontal ligament space. The most commonly performed treatment was root canal therapy. Within the limits of this study, it can be concluded that traumatic dental injuries occur more frequently in young male individuals, due to falls and bicycle accidents. Subluxation was the most common type of periodontal ligament injury. Root canal therapy was the type of treatment most commonly planned and performed.

  9. INVOLVEMENT OF SYNAPTIC GENES IN THE PATHOGENESIS OF AUTISM SPECTRUM DISORDERS: THE CASE OF SYNAPSINS

    Directory of Open Access Journals (Sweden)

    Silvia eGiovedi

    2014-09-01

    Full Text Available Autism spectrum disorders (ASDs are heterogeneous neurodevelopmental disorders characterized by deficits in social interaction and social communication, restricted interests and repetitive behaviors. Many synaptic protein genes are linked to the pathogenesis of ASDs, making them prototypical synaptopathies. An array of mutations in the synapsin (Syn genes in humans have been recently associated with ASD and epilepsy, diseases that display a frequent comorbidity. Synapsins are presynaptic proteins regulating synaptic vesicle traffic, neurotransmitter release and short-term synaptic plasticity. In doing so, Syn isoforms control the tone of activity of neural circuits and the balance between excitation and inhibition. As ASD pathogenesis is believed to result from dysfunctions in the balance between excitatory and inhibitory transmissions in neocortical areas, Syns are novel ASD candidate genes. Accordingly, deletion of single Syn genes in mice, in addition to epilepsy, causes core symptoms of ASD by affecting social behavior, social communication and repetitive behaviors. Thus, Syn knockout mice represent a good experimental model to define synaptic alterations involved in the pathogenesis of ASD and epilepsy.

  10. The Future of the Food System: Cases Involving the Private Sector in South Africa

    Directory of Open Access Journals (Sweden)

    Laura M. Pereira

    2013-03-01

    Full Text Available The food system is facing unprecedented pressure from environmental change exacerbated by the expansion of agri-food corporations that are consolidating their power in the global food chain. Although Africa missed the Green Revolution and the wave of supermarket expansion that hit the West and then spread to Asia and Latin America, this is unlikely to continue. With a large proportion of sub-Saharan African countries’ GDP still heavily reliant on agriculture, global trends in agri-food business are having an increasing impact on African countries. South Africa, a leader in agribusiness on the continent, has a well-established agri-food sector that is facing increasing pressure from various social and environmental sources. This paper uses interview data with corporate executives from South African food businesses to explore how they are adapting to the dual pressures of environmental change and globalisation. It shows that companies now have to adapt to macro-trends both within and outside the formal food sector and how this in turn has repercussions for building sustainable farming systems—both small and large-scale. It concludes with the recognition that building a sustainable food system is a complex process involving a diversity of actors, however changes are already being seen. Businesses have strategically recognised the need to align the economic bottom line with social and environmental factors, but real sustainability will only happen when all stakeholders are included in food governance.

    A 50-year-old female presented with right painful abducens nerve palsy persisting for 4 months and mild panhypopituitarism with diabetes insipidus for 6 months. T(1)-weighted magnetic resonance (MR) imaging of the sellar region showed a homogeneously enhanced mass lesion in the right cavernous sinus which seemed to extend from the swollen pituitary gland. T(2)-weighted MR imaging clearly showed the mass in the right cavernous sinus and the thickened dura mater of the sellar floor as hypointense, and the enlarged pituitary gland as isointense. Biopsy of the thickened dura mater and swollen pituitary gland was performed via the transsphenoidal approach. Histological examination revealed inflammation and collagen fiber formation in these regions. The diagnosis was secondary panhypophysitis resulting from granulomatous pachymeningitis involving the cavernous sinus (Tolosa-Hunt syndrome). Corticosteroid therapy was begun after the biopsy. Her periorbital pain and diplopia were relieved, but diabetes insipidus persisted. Follow-up MR imaging showed a decrease in the volumes of the pituitary gland and the mass in the cavernous sinus.

    Full Text Available I teach an upper-level writing course, Genes, Race, Gender, and Society, designed for Life Science majors, in which I utilize a case study to expose students to ethical ways of thinking.  Students first work through the topical case study and then are challenged to rethink their responses through the lenses of ethics, taking into account different ethical frameworks.  Students then develop their own case study, integrating ethical components.  I want to expose my students to this way of thinking because I see technology being driven by the Jurassic Park phenomenon, "Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should." and want future physicians grounded in a sense of how their actions relate to the greater good.

    As a continuation from summer 2012, the Shuttle Case Study Collection has been developed using lessons learned documented by NASA engineers, analysts, and contractors. Decades of information related to processing and launching the Space Shuttle is gathered into a single database to provide educators with an alternative means to teach real-world engineering processes. The goal is to provide additional engineering materials that enhance critical thinking, decision making, and problem solving skills. During this second phase of the project, the Shuttle Case Study Collection website was developed. Extensive HTML coding to link downloadable documents, videos, and images was required, as was training to learn NASA's Content Management System (CMS) for website design. As the final stage of the collection development, the website is designed to allow for distribution of information to the public as well as for case study report submissions from other educators online.

    A schwannoma, also called neurilemmoma, is a benign, encapsulated, slow growing tumor arising from the neural sheath's Schwann cells of the peripheral, cranial or autonomic nerves. The etiology is unknown, there is no gender preference and the tumors occur most commonly between the ages of 20 and 50 years. Approximately 25-48% of these tumors occur in the head and neck region, with only 1% occurring in the mouth. The current case reports a schwannoma of the tongue, found in a 12 year-old boy. The lesion was present for 6 months. The clinical examination revealed a 1.5x1.0 cm, sessile, rubbery, non-tender non-ulcerated mass on the right posterior lateral border of the tongue. An excisional biopsy was performed under local anesthesia. The histological sections showed a circumscribed submucosal nodule composed of spindle cells with thin wavy nuclei arranged as typical Antoni A (with Verocay bodies) and Antoni B areas. Nuclear palisading distribution (typical of a schwannoma) was readily identifiable. The patient was recurrence free after one year.

    Wind farm repowering involves the replacement of smaller and middle sized wind turbines, with state-of-the-art multi-megawatt turbines. In this paper, a detailed study of the repowering of a wind farm is presented, by computing the generated active power from existing wind turbines and the new ones. The active power generated with the wind turbines are totalized to obtain the yearly generated energy and analyzed, thus economic studies take the repowering cost into account too. (au)

    Full Text Available This paper discusses what the methods of conversation analysis (CA might have to offer the study of linguistic synonymy. It takes as a case study two items commonly held to be synonyms -'actually' and 'in fact'- and shows considerable differences between the two in their interactional implementation: they are implicated in the prosecution of differing courses of action. Such cases argue that it is analytically more profitable to consider what a lexical item does in the context of talk than what it means.

    Axillary lymph node metastasis without breast involvement from ovarian cancer is rare. We report a case of a 68-year-old woman proven as ovarian serous papillary carcinoma and metastatic papillary carcinoma of the omentum on surgical diagnostic laparoscopy. In addition, a hypermetabolic lymph node was detected in left axilla and was considered a reactive benign lesion. Mammography and ultrasonography showed no focal lesion in both breasts, but ultrasonography-guided core needle biopsy for the lymph node revealed metastatic serous papillary carcinoma from ovarian origin. Even with a low incidence of axillary lymph node metastasis without breast involvement from ovarian cancer and only marginally elevated standardized uptake value in positron emission tomography, the possibility of metastasis at axillary lymph node in patients with known primary ovarian cancer must be considered.

    Lichen planus is a chronic autoimmune, mucocutaneous disease, which can affect the oral mucosa, skin, genital mucosa, scalp and nails, and commonly seen in adults. Childhood lichen planus is a rare entity, which is characterized by skin lesions with the oral involvement being extremely uncommon. There are only a few reports on this subject in the literature. Early and correct diagnosis with adequate management is very important to avoid further complications as it is a pre-malignant condition. Herewith, we report a seven-year-old girl having erosive oral lichen planus with cutaneous involvement, which responded well to the treatment. This is to add another case of lichen planus in a child and to emphasize its consideration in the differential diagnosis of oral mucosal red and white lesions in children.

    The current ubiquity of functional neuroimaging studies, and the importance they have had in elucidating brain function, obscures the fact that much of what we know about brain-behavior relationships derives largely from the study of single- and multiple-patient cases. A major goal of the present review is to describe how single cases continue to uniquely and critically contribute to cognitive neuroscience theory. With several recent examples from the literature, we demonstrate that single cases can both challenge accepted dogma and generate hypotheses and theories that steer the field in new directions. We discuss recent findings from case studies that specify critical functions of the hippocampus in episodic memory and recollection, and clarify its role in nonmnemonic abilities. Although we focus on the hippocampus, we discuss other regions and the occurrence of new associative learning, as well as the involvement of the ventromedial prefrontal and parietal cortices in memory encoding and retrieval. We also describe ways of dealing with the shortcomings of case studies, and emphasize the partnership of patient and neuroimaging methods in constraining neurocognitive models of memory.

    Research is lacking on differing perspectives regarding custody cases involving domestic violence (DV). In a survey of judges, legal aid attorneys, private attorneys, DV program workers, and child custody evaluators (n = 1,187), judges, private attorneys, and evaluators were more likely to believe that mothers make false DV allegations and alienate their children. In response to a vignette, evaluators and private attorneys were most likely to recommend joint custody and least likely to recommend sole custody to the survivor. Legal aid attorneys and DV workers were similar on many variables. Gender, DV knowledge, and knowing victims explained many group differences.

    Meningitis and/or encephalitis can pose a serious public health problem especially during outbreaks. A rapid and accurate diagnosis is important for effective earlier treatment. This study aimed to identify the possible microbial causes of meningitis and/or encephalitis cases. CSF and serum samples were collected from 322 patients who had signs and symptoms suggestive of meningitis and/or encephalitis. Out of 250 cases with confirmed clinical diagnosis, 83 (33.2%) were definitely diagnosed as bacterial meningitis and/or encephalitis cases (by using CSF culture, biochemical tests, latex agglutination test, and CSF stain), 17 (6.8%) were definitely diagnosed as having viral causes ( by viral isolation on tissue culture, PCR and ELISA), and one (0.4%) was diagnosed as fungal meningitis case (by India ink stain, culture, and biochemical tests). Also, there was one encephalitis case with positive serum ELISA IgM antibodies against Sandfly scilian virus. N. meningitidis, S. pneumonia and M. tuberculosis were the most frequently detected bacterial agents, while Enteroviruses, herpes simplex viruses and varicella zoster viruses were the most common viral agents encountered. Further studies are needed to assess the role of different microbial agents in CNS infections and their effective methods of diagnosis.

    Full Text Available BACKGROUND We have studied 200 patients of pleural fluid presenting to our tertiary care centre. Presence of cases of pleural fluid is a common presentation both in pulmonary and extrapulmonary diseases. We analysed the patients having both exudates and transudates and studied the results. MATERIALS AND METHODS We selected patients above 20 years of age and classified the patients with pleural fluid as having transudates and exudates. We studied the causes of transudates and exudates. A total of 200 patients are studied in this prospective study. Diagnosis of pleural exudates is made on the basis of Light’s criteria, chest x-ray, pleural fluid analysis, CT scan in selected patients, sputum examination, bronchoscopy and bronchial washings. Moribund and non-cooperative patients and HIV positives were excluded from the study. RESULTS Among the 200 patients, 91% have exudates. 9% have transudates by Light’s criteria. Tuberculosis is the commonest cause of effusions (64.83% followed by malignancy (13.73% and sympneumonic or parapneumonic effusions (9.89%. Pleural effusions occurred predominantly in males. Prevalence of diabetes Mellitus among cases of tuberculous pleural effusions is 13.56%. Tuberculous effusions are predominantly right-sided. CONCLUSION Predominant cases of pleural fluid are exudates. Commonest cause of pleural effusion is Tuberculosis followed by malignancy both pulmonary and extrapulmonary and sym. and parapneumonic effusions. Prevalence of Diabetes among Tuberculous pleural effusion cases is more or less same as in general population. Cough, expectoration fever, chest pain and breathlessness are the common symptoms occurring in three fourths of the patients of tuberculous pleural effusion. Most of the cases of Tuberculous effusion are above 30 years of age. In the diagnosis of tuberculous pleural effusion, Pleural fluid ADA is very important.

    Full Text Available Infection with dengue virus results in a wide range of clinical manifestations from dengue fever (DF, a self-limited febrile illness, to dengue hemorrhagic fever (DHF which is characterized by plasma leakage and bleeding tendency. Although cardiac involvement has been reported in dengue, the incidence and the extent of cardiac involvement are not well defined.We characterized the incidence and changes in cardiac function in a prospective in-patient cohort of suspected dengue cases by serial echocardiography. Plasma leakage was detected by serial chest and abdominal ultrasonography. Daily cardiac troponin-T levels were measured. One hundred and eighty one dengue cases were enrolled. On the day of enrollment, dengue cases that already developed plasma leakage had lower cardiac index (2695 (127 vs 3188 (75 (L/min/m2, p = .003 and higher left ventricular myocardial performance index (.413 (.021 vs .328 (.026, p = .021 and systemic vascular resistance (2478 (184 vs 1820 (133 (dynes·s/cm5, p = .005 compared to those without plasma leakage. Early diastolic wall motion of the left ventricle was decreased in dengue cases with plasma leakage compared to those without. Decreased left ventricular wall motility was more common in dengue patients compared to non-dengue cases particularly in cases with plasma leakage. Differences in cardiac function between DF and DHF were most pronounced around the time of plasma leakage. Cardiac dysfunction was transient and did not require treatment. Transient elevated troponin-T levels were more common in DHF cases compared to DF (14.5% vs 5%, p = 0.028.Transient left ventricular systolic and diastolic dysfunction was common in children hospitalized with dengue and related to severity of plasma leakage. The functional abnormality spontaneously resolved without specific treatment. Cardiac structural changes including myocarditis were uncommon.
