Endoscopic treatment and management of frontalethmoidal mucopyocele with orbital extension: a case report
No full textThe aim of this case report was to report the presentation, the management and the treatment of extensive frontoethmoidal (FOE) mucopyocele. In this case report the authors present the clinical case of a 50-year old woman that came in to the emergency room with acute clinic symptom: esoftalmic and with righteye hypomobility, pain, diplopic, without alteration of optical nerve functionality. With TC and RM exams, an extended monolateral mass at the basemant on the right orbit and perifocal bones profile deformation was identified. As a result of these characteristics an Endoscopic Surgery treatment was chosen. The patient is currently free of any clinical symptoms, she has completely reacquired visual function, without intra or post surgical complications. The mucopyocele can interest every paranasal sinus. In this case report we analyzed the treatment of the frontoethmoidal mucopyocele with endonasal endoscopic surgery that permitted to avoid coronal surgery, wich is considered more invasive, along with a higher probability of complications (liquorrea) and eventual aesthetic problems. The case proposed, evidences the necessity of modern surgeon to include is their capabilities those of alternative surgery techniques that are much more efficient
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
The role of core needle biopsies in the management of neck lumps
Get PDFBackground: King's College Hospital has proudly provided a one-stop neck lump clinic since 2012. These multidisciplinary clinics allow for rapid diagnoses due to in-clinic investigations. In April 2013, ultrasound-guided core needle biopsies (CB) were introduced as an alternative/adjunct to fine needle aspiration cytology (FNAC) and open biopsies for obtaining histo- logical diagnoses.
Aim: To assess the impact of CB on the diagnosis of neck lumps compared to FNAC and open biopsies between April 2015 and May 2016.
Method: Data was collected prospectively between April 2015 and May 2016 and analysed for numbers of FNAC, CB and open biopsies performed and diagnoses made.
Result: 190 patients were seen on the clinic. 51 had a FNAC and 19 gave a diagnosis. Out of the remainder of these patients, 21 had a CB, and 12 gave a diagnosis. 8 only had a CB, of which 5 gave a diagnosis. 10 had an open biopsy; 4 had a previous FNAC and CB, 3 only a CB, 2 had neither and 1 had a FNAC.
Conclusion: The introduction of CB has reduced the number of open bi- opsies performed. With increasing acceptance of this minimally-invasive technique, CB appear to be forming the key diagnostic investigation in patients with neck lumps
