Chistul arahnoid al fisurii silviene: diagnosticul si tratamentul endoscopic
Get PDFChistul arahnoid al fisurii silviene (SAC) este o localizare bine recunoscută pentru chisturile arahnoide intracraniane la copii. Aceste
tipuri de formațiuni chistice sunt depistate destul de frecvent la examenul imagistic intracranian la copii. Au fost raportate mai multe
modalități de tratament, inclusive cele endoscopice. Raportam rezultatele clinice și radiologice ale fenestratării endoscopice ale acestor chisturi.A Sylvian fissure arachnoid cyst (SAC) is a well-recognized location for an intracranial arachnoid cyst in the pediatric population. They are a frequent finding on intracranial imaging in children. Several treatment modalities have been reported. We report
clinical and radiological outcome of fenestration of these cysts by endoscopy
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
Tumorile intracerebrale la copii
Get PDFBackground. Brain tumors of the central nervous system for children are (2.5-3.5 per 100,000 children
per year) an important part of daily practice in pediatric oncology. Brain tumors are very heterogeneous
in terms of tissue, location, pattern of spread, clinic and age of onset from neonatal to
adolescence. Objective of the study. The study features of brain tumor outcome depending on
histology, location and age of children. Material and Methods. We presents a retrospective study
comprising 84 children aged 0-18 years, diagnosed with brain tumors, who were hospitalized in the
National Scientific-Practical Center of Pediatric Surgery "Academician Natalia Gheorghiu" of IMSP
ImșiC. Results. We report the evolution of brain tumors during the period 2010-2018 with descriptive
classification based on histopathological examination and location, which is the basic element for the
proper management of brain tumors in the child. Medulloblastomas 34 patients (40.4%), Ependymomas
25 (29.7%), oligodendrogliomas 9 (10.7%), Astrocytomas 16 (19%). Depending on the location,
infratentorial tumors prevail over supratentorial tumors. The most common incidence of tumors were
cerebellar vermis, medulloblastomas being the dominant type. In the case of supratentorial tumors,
tumors of the celestial region and ventricle III predominated. Conclusion. The multidisciplinary,
personalized approach and the efficiency of early screening and diagnosis allowed to obtain a
satisfactory result and a good prognosis. Introducere. Tumorile cerebrale ale sistemului nervos central pentru copii constituie (2,5-3,5 la 100
000 de copii anual), o parte importantă a practicii zilnice în oncologia pediatrică. Tumorile cerebrale
sunt foarte eterogene în ceea ce privește țesutul, localizarea, modelul de răspândire, clinica și vârsta de
debut de la nou-născut până la adolescență. Scopul lucrării. Studiul particularităților de evoluție a
tumorilor cerebrale, în funcție de histologie, localizare și vârsta copiilor. Material și Metode. Lucrarea
prezintă un studiu retrospectiv, cuprinzând 84 de copii cu vârsta de 0-18 ani, cu tumori cerebrale,
internaţi în Centrul Național Științifico-Practic de Chirurgie pediatrică „Academician Natalia
Gheorghiu” al IMSP ImșiC. Rezultate. Raportăm evoluția tumorilor cerebrale pe parcursul perioadei
2010-2018, cu clasificarea descriptivă, bazată pe examenul histopatologic și localizare, care este
elementul de bază pentru gestionarea adecvată a tumorilor creierului copilului. Meduloblastoame - 34
pacienți (40.4%), Ependimoame -25(29.7%), oligodendroglioame - 9(10.7%), Astrocitoame - 16(19%).
În funcție de localizare, prevaleaza tumorile infratentoriale față de cele supratentoriale.Cea mai
frecventă incidenţă a tumorilor au fost de vermis cerebelos, meduloblastoamele fiind tipul dominant. În
cazul tumorilor supratentoriale, au predominat tumorile de regiune selară și ventricul
III. Concluzii. Abordarea multidisciplinară, personalizată și eficientizarea screening-ului și a
diagnosticului precoce a permis obţinerea unui rezultat satisfăcător şi a unui prognostic bun
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
