Complicaciones de cirugía ortognática mandibular: revisión de la literatura a propósito de un caso.
No full textLa cirugía Ortognática Sagital Bilateral de Rama Mandibular (OSBRM) es la técnica más
utilizada para corregir las anomalías dento-maxilofaciales. En este tipo de intervenciones se
realizan una serie de maniobras quirúrgicas que podrían ocasionar complicaciones en el
paciente, mismas que han sido documentadas y clasificadas bibliográficamente. En el presente
trabajo se reporta el análisis de un caso clínico con seguimiento a 10 años de un paciente que
presentó una complicación intraoperatoria de cirugía ortognática que fue no resuelta; el
paciente es asintomático y muestra una significativa desviación mandibular hacia la derecha,
buscó una solución debido a la inconformidad estética causada por el fracaso de una cirugía
ortognática mandibular. Las evaluaciones presuntivamente denotan que las complicaciones
fueron la ausencia de la cabeza condilar de la hemimandíbula afectada derecha y una fractura
no deseada a nivel condilar, también denominada Condylar Sag, cuadro que al no ser corregido
generó un desplazamiento del segmento proximal mandibular. Adicionalmente, se presenta
una revisión de la literatura donde se detallan las fracturas intraoperatorias; la investigación
considera artículos publicados desde el 2013 al 2023, que ayudaron a concluir lo complejo que
es determinar el porcentaje total de posibles fracturas no deseadas provocadas por una
osteotomía mandibular, dado que dependen de varios factores. Sin embargo, se pudo constatar
que no son muy frecuentes, variando entre el 0.9 y 20%, según las series de caso.Bilateral Sagittal Split Ramus Osteotomy (BSSRO) is a commonly employed technique for
correcting dental-maxillofacial anomalies. Despite its effectiveness, this surgical approach can
entail potential complications, which have been documented and categorized in the literature.
In this study, a clinical case analysis with a 10-year follow-up is presented involving a patient
who experienced an unresolved intraoperative complication during orthognathic surgery. The
patient remains asymptomatic but displays a significant mandibular deviation to the right. The
individual sought a solution due to aesthetic discomfort caused by a failure of mandibular
orthognathic surgery. Evaluations indicated that complications stemmed from the absence of
the condylar head in the right hemimandible and an unintentional fracture at the condylar level,
possibly arising from a bad split. When not rectified, this situation led to the displacement of
the proximal mandibular segment. Additionally, a literature review is presented, outlining
potential intraoperative fractures. This review considers articles published from 2013 to 2023,
contributing to the understanding that assessing the precise frequency of unwanted fractures
due to mandibular osteotomy is complex, as it depends on several factors. However, it was
found that such occurrences are relatively infrequent, ranging from 0.9% to 20% depending on
the case series.Trabajo de investigació
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
