Teratome sacro-coccygien : aspects epidemiologique, clinique et therapeutique au CHU Gabriel Touré
No full textNous rapportons 15 cas de TSC colligés au service de Chirurgie Pédiatrique du CHU Gabriel Touré de Bamako, durant une période de 5 ans allant du Janvier 2009au Décembre 2013. Le but de notre étude rétro et prospective est d'étudier les aspects épidémiologiques, cliniques et thérapeutiques, des tératomes sacrococcygiens. Dans cette étude, on a noté une prédominance féminine (80% des filles pour 20% des garçons). Le diagnostic a été évoqué en anténatal pour un seul patient, grâce à l'échographie obstétricale du 3ème trimestre. Pour les autres patients, la masse a été découverte à lanaissance. Toutefois, deux patientes n'ont été vues que tardivement (au 6ème mois d'âge) vu que les familles n'ont pas consulté plutôt. Aucun de nos patients ne présente des antécédents familiaux de TSC ni de gémellité. L'accouchement par voie basse a été effectué chez 14 patients (93,3%), et par voie haute chez 1 patients (6,7%). La masse tumorale était le motif de consultation dans tous les cas. L'examen clinique a objectivé des masses sacrococcygiennes, dont les tailles variaient entre 7 et 38 cm avec une moyenne de 17 cm. La consistance était kystique dansla moitié des cas. L'anus était refoulé en avant dans 11 cas(73,33%) des cas. L'examen malformatif n'a pas trouvé de malformation associé . Les radiographies standards réalisées chez tous les malades, n'ont pas révélé de défect osseux ni de malformations rachidiennes. Les calcifications ont été mises en évidence chez deux patients (13,33%). L'échographie abdomino-pelvienne réalisée chez 3patients, a objectivé une masse sacrococcygienne d'échostructurehétérogène évoquant le TSC, sans compressions urinaire ou/et digestive. L'IRM et la TDM n'ont étéréalisée dans cette étude en raison du coût et de manque de plateau technique. Le dosage des marqueurs tumoraux a été effectué chez tous les patients ; le taux d'AFP est revenu élevé dans 13 cas, et normal dans deux cas. Le taux de β-HCG est revenu négatif dans les 7 cas. Un bilan de retentissement et préopératoire a été réalisé chez tous les patients. Tous les patients opérés ont subi une intervention par voie périnéale, consistant à une exérèse complète de la tumeur associée à une coccygectomie. Le diagnostic a étéconfirmé par l'étude anatomo-pathologique chez tous les malades ; revenant en faveur d'un tératome mature dans 12 cas et un tératome immature dans 3 cas. Aucun de nos patients n'a réçu une chimiothérapie palliative. L'évolution postopératoire a été marquée par la surinfection de la plaie dans 9 cas et un cas d'incontinence urinaire. L'évolution au long cours a été bonne pour 12 patients avec un recul de 9 mois en moyenne. Deux patients sont perdus de vue. U
L'artisanat traditionnel des peaux et cuirs de la ville de Djenné au Mali
No full textTraditional hide and leather handicrafts of Djennè (Mali) are in the abandon. Markets are shrinking just as the number of artisans is diminishing. The few artisans, who are struggling to make it their daily vocation, limit themselves to activities of repairing and creating small leather products that are sold for a minimal amount. The income from these activities is insufficient to even cover the daily expenses of their families, all the more since they use up their savings. Therefore, this text titled “traditional hide and leather handicrafts of the city of Djennè “aims, on the one hand, at establishing a relation between this handicraft and the administrative, environmental, historical and socio-professional contexts and on the other hand, analyses its technical complexities. And finally, after shedding light on the strengths and weaknesses of the hide and leather handicrafts of Djennè, some of the values that contribute to its heritage characteristics will be explained before suggesting strategies of enhancement of this heritage in order to make it a valuable element of local sustainable developmen
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
