    Pancreatic pseudocyst eroding into the splenoportal venous confluence and mimicking an arterial aneurysm

    Get PDF
    We report the case of a 62-year-old man with chronic pancreatitis who presented with increasing abdominal pain. Sonography, magnetic resonance imaging, contrast-enhanced computed tomography, and ultimately catheter angiography demonstrated a pancreatic pseudocyst that had eroded into the splenoportal venous confluence, mimicking an arterial aneurysm. The diagnostic was confirmed at the time of surgical treatment. This case demonstrates the use of imaging to diagnose complications of pancreatitis, and the difficulty of distinguishing an eroding pseudocyst from an arterial aneurysm

    Giving in Transition and Transitions in Giving: Philanthropy in Egypt, Libya and Tunisia 2011-2013

    Get PDF
    This publication explores how shifts in the sociopolitical environment in Egypt, Libya and Tunisia manifested themselves in the philanthropic realm during an uncertain mid-point in the transitions. To what extent have both institutional and informal philanthropy evolved to keep up with the pace of escalating needs and expectations of the people? As those shifts continue in all three countries, with variations to be explored in each country chapter, the report encourages actors in the sector to take bolder steps from diagnostics to action

    Biomimetic Potentials for Building Envelope Adaptation in Egypt

    AbstractBiomimicry is a science that seeks sustainable solutions by emulating nature's time-tested 3.8 billion years of patterns and strategies. The paper is concerned with embodying the biomimetic strategies to building envelopes which shall offer a high potential to reduce the energy demand, save material and thus improve the sustainability of buildings, through accessing current practices process of natural ventilation biomimicry in buildings for a potential application in building envelope for environmental adaptation which could help for the emergence of a new generation of biomimetic building envelopes aiming at promoting biomimicry in Egypt by showing the benefits that could be harvested

    The Impact of the Faculty of Medicine, University of Gezira, Innovative Programme on its Graduates

    Introduction: Programme evaluation is the collection and interpretation, through systemic and formal means, of relevant information which serves as a basis for rational judgment in decision situations. This study was conducted as part of the third programme development of the Faculty of Medicine, Gezira University 2010 – 2011. Objectives: The general objective is to study the impact of the Faculty of Medicine, Gezira University, innovative programme, on its graduates. The specific objectives include the evaluation of graduates' competences in the three main areas of domain of learning, i.e. Knowledge, skills and attitude. Materials and Methods: This is a Cross-sectional Study conducted in the period from13th. of January to 12th. of February 2011. The study population includes 146 consultants who have Gezira graduates training with them including house officers, medical officers and registrars. Excluded from the study all consultants who are academic staff members in the FMUG, who are Gezira graduates or who are involved in student training. A questionnaire was designed to answer the questions that address the objectives of the study covered in 32 questions, using a grading scales; 1 to 5: where 1= poor; 2= less than average, 3= average; 4= good; 5= excellent. Results: the response rate for the questionnaire was 73% (146/210), representing 146 consultants working in 23 hospitals in 12 cities. In the overall evaluation of graduates΄ knowledge and cognitive abilities, graduates were rated as good to excellent in (68.3%), average in (25.12%) and poor to below average in only a minority of the graduates. In the overall evaluation of graduates΄ skills and competences, graduates were rated as good to excellent in (72.33%), average in (20.81%) and poor to below average in only a minority of the graduates. In the overall evaluation of attitudes and ethical standards, graduates were rated as good to excellent in the majority (84.06%). In the overall classification, graduates were rated as good to excellent in the vast majority (82.6%), average in the minority (14.5%) and poor to below average in only a few cases. Conclusion The evaluation of graduates' competences is an important element in the educational programme evaluation. These results provide evidence in favour for the innovative educational programme and can encourage other medical schools to adopt it. Further studies are needed to cover other aspects of graduates' evaluations

    Butterflyfishes (Chaetodontidae) from Abu Hashish fringing reefs, Port Sudan, Red Sea

    Using Reef Check Programme butterflyfishes of Abu Hashish fringing reefs were recorded during 2003 and 2013. The results showed that the numbers of species declined from nine to seven. Chi square test revealed that the number of butterflyfishes significantly decreased (p<0.00001). This reduction was attributed to continuous construction and anthropogenic actives Keywords: Butterflyfishes, Abu Hashish, Port Suda

    An ISH technique for the early detection of Enterospora nucleophila, an intranuclear microsporidian causing emaciative disease in gilthead sea bream

    Get PDF
    Enterospora nucleophila is a microsporidian parasite causing serious emaciative disease in cultured gilthead sea bream (GSB), Sparus aurata, and closely related to Enterocytozoon hepatopenaei from shrimp. The parasite can be found within the nuclei of enterocytes and rodlet cells of the fish intestinal epithelium, and occasionally in the cytoplasm of phagocytes in more advanced infections. However, spores are the only stage that can be unmistakably identified but even this may require thorough histopathological examination and use of chitin fluorescent stains for a proper confirmatory diagnosis, due to their minute size and intranuclear location. In the absence of spores, the infection can be suspected from a remarkable hypercelullarity and the presence of altered nuclei in the epithelial layer. This results in a very poor correlation of disease signs with diagnosis of E. nucleophila infection, and to current uncertainty about its real impact in GSB culture. This work describes the development and application of an in situ hybridization (ISH) technique as a powerful tool to overcome current diagnostic limitations for this species, and to decipher basic data on the infection and disease onset. We designed DIG-labelled oligonucleotide probes targeting unique regions of the (+) strand of E. nucleophila rDNA gene, and we developed an ISH protocol that results in good staining of infected host cells prior to the development of spores or other conspicuous stages. On clinically infected samples, numerous ISH-positive cells are present which are not stained with fluorescent whiteners that bind to parasite spores. In contrast, poor staining of spores was obtained with the DNA probes, due to their limited penetration in these stages and the low number of target gene copies that they harbour. These aspects might be improved using specific steps (e.g., chitinase or more aggressive permeabilization strategies) but they are not necessary in a clinical diagnostic context. Due to the relevance of E. nucleophila infections it is essential to decipher unknown aspects of the parasite\u2019s biology and course of infection using proper diagnostic tools. Their cryptic nature makes this a challenging task for microsporidians like E. nucleophila, which can benefit from the method hereby presented
