Paralisi periferica monolaterale del VII nervo cranico da riattivazione di virus varicella zoster: la sindrome di Ramsay Hunt
No full textRamsay Hunt syndrome is the second leading cause of peripheral facial palsy in children, and it is due to reactivation of Varicella Zoster Virus. A characteristic feature of this syndrome is the triad of ipsilateral facial palsy, otalgia and vesicular rash in the auricle or auditory canal. The diagnosis is clinical, and currently there is no international protocol on its paediatric management and treatment. The paper reports the case of a 10-year-old girl, who presented with symptoms suggestive of peripheral facial palsy and, consequently, was treated with steroid therapy at first. After the appearance of vesicles in the auricular site and having ruled out the other causes of peripheral paralysis of the VII cranial nerve, antiviral therapy was undertaken and, given the poor clinical improvement, was later enhanced corticosteroid therapy. One month after onset, the child recovered completely
Quando l'anemia blocca le gambe
No full textViene riportato il caso di una bambina di un anno e 5 mesi con severa anemia cronica ferrocarenziale con regressione nella deambulazione che aveva acquisito. È idocumentato in letteratura come ci sia una correlazione tra lo stato marziale dei bimbi e il neurosviluppo, con particolare coinvolgimento della motricità, soprattutto della deambulazione. Le cause di queste implicazioni nella motricità sono legate sia alla fatigue e alla letargia tipiche dell’anemia cronica sia a un’alterata composizione della mielina
Profilassi con vitamina D nel lattante: l’importanza di capirsi bene
No full textThe paper describes a case of intoxication from vitamin D in a 35-day infant of exclusive breastfeeding life who was administered 8000 IU of vitamin D per day over 4 weeks. There was an important linguistic barrier with her mother. The clinical picture was exclusively characterized by constipation, with adequate growth. Laboratory investigations showed calcemia at upper limits (11.1 mg/dl), elevated levels of 25-OH vitamin D3 (25-OH), equal to 375 μg/l, and renal ultrasound finding compatible with microlithiasis. The clinical picture was resolved with an intravenous hydration and suspension of vitamin supplementation. The case shows that in a situation in which there is a condition of family vulnerability it is necessary to make sure that any prescription has been correctly understood
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
