Apport de l'imagerie dans les ischemies entero-mesenteriques
Buts du travail :
Préciser la sensibilité des examens d’imagerie. Calculer la fréquence des éléments sémiologiques radiologiques des ischémies entéro-mésentériques selon leurs étiologies.
Déterminer l’apport pronostique de l’imagerie, et évaluer la prise en charge diagnostique et thérapeutique, par une analyse rétrospective de 46 dossiers
Matériels et méthodes :
39 patients hospitalisés en urgence entre janvier 2003 et novembre 2007, recueillis à partir de trois service d’urgence chirurgicale de réanimation et de radiologie. Une étude rétrospective des données cliniques, biologiques, radiologiques, thérapeutiques, et anatomopathologiques a été effectuée pour chaque dossier.
Résultats :
La radiographie de l’abdomen sans préparation n’est pas contributive. La rentabilité de l’échographie est moindre que celle de la tomodensitométrie. Quant à l’imagerie par résonance magnétique, sa sensibilité apparaît superposable à celle de la tomodensitométrie, mais son coût nécessite de la réserver aux contre-indications à l’injection de produits iodés.
La sensibilité du scanner a été estimée à 71,43%.
L’atteinte ischémique d’origine artérielle aiguë a été retrouvée chez 8 patients, elle se manifestait dans 66,67% des cas par une paroi intestinale mince, avec un défaut de réhaussement, absent dans 33,33% des cas réalisant l’aspect de la paroi virtuelle, et modéré dans 66,67%, avec des signes de gravité: la pneumatose pariétale dans 50% et la topographie multifocale dans 83,33%. L’atteinte subaiguë s’est révélée par un épaississement pariétal modéré dans un cas et important dans l’autre. Parmi les 7 patients décédés, les 6 patients qui ont bénéficié d’un scanner abdominal présentaient des signes de gravité tomodensitométriques.
L’atteinte ischémique d’origine veineuse a été diagnostiquée chez 9 patients, un épaississement pariétal était présent dans tous les cas, important (≥15mm) dans 50% des cas, et modéré dans 50% des cas, associé à un amincissement par endroits dans les deux cas ou la thrombose a été étendue au tronc porte. Les signes d’obstruction sont observés dans 75% des cas, la densification de la graisse mésentérique a été notée dans 87,5% des cas. Les 7 patients décédés présentaient une atteinte multifocale importante, une pneumatose pariétale dans 57,17%, associée à un épanchement liquidien dans tous les cas.
L’atteinte ischémique d’origine non occlusive a été décelée chez 4 patients, l’amincissement avec un défaut de réhaussement et les signes de gravité ont été retrouvés dans un seul cas.
La mortalité précoce est estimée à 80,65%.
Conclusion :
Le scanner permet de différencier entre l’origine artérielle et veineuse de l’ischémie entéro-mésentérique, à condition d’une bonne appréciation des éléments sémiologiques discriminants. Il permet également d’apprécier le pronostic par la recherche des signes de gravité, permettant ainsi une meilleure prise en charge, qui ne se conçoit que dans le cadre d’une approche multidisciplinaire simultanée, rapide et précoce, associant le radiologue,l’anesthésiste réanimateur,le chirurgien viscérale et vasculaire
LE ROI DE KAHEL ET LE TERRORISTE NOIR DE MONENEMBO: UNE REECRITURE POSTCOLONIALE DE L’HISTOIRE
The historical evolution of the African continent was not smooth; the region experienced many upheavals including two powerful traumas that are slavery and colonialism. It is therefore not surprising that African writers, who are mainly inspired by the world around them, revisit History to write their novels. Among them, the Guinean writer Tierno Monénembo. The writer sheds the light on the history that has painfully shaken his continent, West Africa more precisely. His novels translate the almost obsessive concern to narrate the story of the African continent. We propose to study two of his novels: The king of Kahel (2008) and The black terrorist (2012). In these novels, the author offers a different reading of colonial memory, moving away from the long-standing Manichaeism between white and black. Through the romanticized biography of Viscount Sanderval - driven by a sincere desire to civilize the negroes but at the same time to conquer a kingdom in the region of Fouta-Djalon-, or that of Addi Bâ, a young Senegalese gunner who will enter, during the Second World War, in France, the reader is invited to dive into a troubled past and discover all the complexity of Franco-African politics. Our purpose is to show the way History fits in the novels of Monénembo, by studying literary devices in the novels as well as the representation of two historical figures: Sanderval and Addi Bâ
Style in Translation A Comparative Stylistic Analysis of The Sand Child by Tahar Ben Jelloun
Recently, Theorists began to think that studying language linguistically is insufficiently beneficial, literary critics also believed that a mere literary analysis easily fall into dilemma, because the scope of their work deals only with language as a combination of words to convert message. Some questions whether the language expressed in literature may carry beyond what is supposed and that affects a generation of thoughts. A systematic wide range interdisciplinary seemed to find answers in the highly specialized language studies; this is what stylistics shows as it concerns. The interdisciplinary nature of the field means that stylistics typically cooperates some acquaintance with linguistics. As far as our research concerns, we attempted to purposefully relate this discipline with literary translation.
The main research question that leads us to accomplish this research paper was if the translator ability to transform the style of the original author would implicitly or explicitly transfer the meaning embedded in those stylistic features of the original text. A comparative analysis has to be underlined so we can grasp the traces of stylistic aspects in both translated and original texts. The Sand Child looked the best example for many reasons, mentioned in paper; we tried to provide a systematic analytic comparison between both styles. Eventually, we figured out the translator may succeed in reaching a faithful translation where he worked to keep stylistics prints of its original author; and thus, meaning upon the two texts is well-communicated. In fact, we believe, stylistics enhances our ability to interpret various meanings. Stylistics is more than studying language; it shortens distance between us and authors. A study that really merits much attention and further studies
"THE CORONA CRASH", BY GRACE BLAKELEY: A BOOK REVIEW
In this note, we come up with a review and presentation of the book “The Corona Crash: How the Pandemic Will Change Capitalism” by Grace Blakeley, a political and economics specialist who had various professional experiences, with companies such as KPMG and IPPR North in England.
In 2019 Grace released her early book, Stolen: How to Save the World from Financialization, She also worked as a journalist and a columnist for Tribune Newspaper.
Through her book - subject of this presentation and review-, the author exposed the fact that the current world has faced an epidemic and financial crisis because of the capitalist policies pursued in the leading countries for decades. In addition, she includes a reflexion by suggesting some solutions that maintain a socialist and environmental approach, based on social justice, solidarity, equality and the environment protecting policies
Women and politics in Algeria: essays on political representation
Gender and politics scholars have sought to determine whether there is a link between women’s descriptive representation, operationalized as the proportion of seats held by women in a national legislature, and women’s substantive representation, usually operationalized as laws that advance women’s rights. But, except for a few studies, the Arab world has not received significant attention which is surprising because the region has experienced a significant increase in women’s presence in politics. Further, most of this work has focused on democratic contexts, obscuring whether hypothesized links between women’s descriptive and substantive representation work in the same way in authoritarian contexts. To fill these gaps in the literature, I focus on the case of Algeria, where women’s presence in parliament increased from 8% to 31.6% after the adoption of a gender quota in 2012.
Drawing on in-depth interviews with a wide range of stakeholders, my research examines the backgrounds of women elected, constituency service priorities, legislative dynamics, and women’s agency. I argue that the “authoritarian toolkit,” i.e., the resources available to authoritarian governments to manage and control political outcomes, shapes women’s descriptive, substantive, and symbolic representation in ways that are distinct from how these dynamics operate in more democratic contexts.
While women parliamentarians reject the notion that they have an obligation to introduce and pass women’s rights laws, they invest time in helping their male and female constituents solve their everyday problems to challenge the notion that women do not belong in politics. Therefore, there may not be strong links between women's descriptive and substantive representation. However, the efforts of elected women on behalf of their male constituents may advance women’s symbolic representation by demonstrating women's abilities in the political realm.Ph.D.Includes bibliographical reference
Apport de l'IRM dans la maladie de Creutzfeldt-Jakob: à propos d'un cas
La maladie de Creutzfeld-Jacob (MCJ) est une affection très rare et fatale qui atteint le système nerveux central. Elle est caractérisée par une détérioration mentale aboutissant à une démence progressive, une symptomatologie pyramidale et extra-pyramidale ainsi que des myolclonies. Un diagnostic précoce est essentiel pour prévenir la transmission interhumaine. Nous rapportons le cas d'un patient âgé de 62 ans chez qui le diagnostic de MCJ sporadique a été retenu, en se basant sur le tableau clinique fait de syndrome démentiel avec myoclonies précédées de troubles du comportement, des hallucinations et de dépression, et sur les données de l'IRM encéphalique qui a montré des hyper signaux au niveau du striatum et au niveau cortical en séquences pondérées Flair et diffusion
Une pneumopathie interstitielle diffuse révélant un syndrome des antisynthétases: à propos de 2 cas
Le syndrome des antisynthétases (SAS) est une myopathie inflammatoire fréquemment associée à une atteinte pulmonaire, surtout parenchymateuse (pneumopathie infiltrante diffuse). Les manifestations extrathoraciques associées à l'atteinte pulmonaire peuvent orienter le diagnostic: myalgies, polyarthralgies, syndrome de Raynaud, hyperkératose érythémateuse palmaire fissuraire et fièvre. Devant un tableau clinique et radiologique évocateur, la présence d'anticorps anti-ARN-t synthétases permet de confirmer notamment les anti-Jo-1. L'atteinte pulmonaire constitue un facteur pronostic majeur d'où l'indication une thérapie immunosuppressive intensive fondée sur la corticothérapie, les immunosuppresseurs ou l'association des deux. Une meilleure sensibilisation pour cette affection à révélation pulmonaire permettra d'adopter une prise en charge rapide et adéquate, et d'améliorer par conséquent le pronostic
Le discours politique des islamistes marocains au pouvoir : le discours populiste
At the end of this chapter entitled "Conflictual affective discourse", the study focused on a number of legitimising discursive strategies mobilised by Benkirane. In fact, the discourses that we have tried to analyse are part of a context marked by a social tension unseen in the history of Morocco (after the Arab Spring). These social realities, marked by a tension, or even a calculation of ideological repositioning between Islamists, communists, socialists, technocrats, etc., are, from the sociolinguistic interactional point of view, manifest in the discourse where the speaker seeks to impose his identity. This observation has led us to set up a typology that better defines this conflictual context, hence the interest in the grid developed by Windisch, whose author insists considerably on the internal functioning of a conflictual discourse produced in a situation of tension.
All the studies aimed at analysing legitimating discourse agree on two fundamental points: on the one hand, discourse is perceived as a linguistic production anchored in symbolic relations of force, negotiation, manipulation and persuasion between individuals; on the other hand, in order for each of them to achieve their objectives, the social actor is confronted with certain constraints in order to convey the meaning he or she aims for. In addressing the issue of dramatization in the so-called populist discourse, Patrick Charaudeau insists considerably on the affective dimension in the interaction with the mass.
Benchmark of Concentrating Solar Power Plants: Historical, Current and Future Technical and Economic Development
AbstractThis paper compares the evolution of Concentrating Solar Power (CSP) Plants. The study is based on a data of 240 CSP plants whose give us a roadmap of technical and economic characteristics of these systems. On the basis of this information collected from the literature, we benchmarked and analyzed the state of the CSP plants from 1982 to 2020. As statistical results show, 87% of CSP projects are located in Spain and USA, but other countries have invested in CSP since 2012. Solar technologies analyzed are Parabolic Trough collector (PTC), Solar Power Tower (SPT), Linear Fresnel Reflector (LFR), and Parabolic Dish Collector (PDC). As detailed data studies for Fresnel and Dish are hardly available, special attention was given to parabolic trough system. The progressive reduction in investment cost of PTC technology over time is presented, taking also into account the energy storage option. Our sensitivity analysis indicates that PTC with thermal oil and molten salt storage at 50 MW is the most mature system, but SPT plants are promising and might have the greatest potential by early 2018
Short Query Expansion for Microblog Retrieval
AbstractTwitter has emerged as the most popular among microblogging service providers. The content provided in Twitter is large, diverse, and huge in quantity. Given the increasing amount of information available through such microblogging sites, it would be interesting to be able to retrieve useful tweets in response to a given information need. However, Twitter's subscribers often have many difficulties dealing with its content. Especially in searching for tweets that satisfy their information needs. This problem becomes more complicated when the user-defined queries are short and precise. This paper deals with short and precise queries problem for micoblog retrieval. We expand short queries by semantically related terms extracted from Wikipedia, DBpedia and unstructured texts using textmining techniques. Experiments on TREC 2011 microblog collection show significant improvement in the retrieval performance
