A history of recurrent wheezing can delay the diagnosis of foreign body aspiration in a paediatric emergency department
No full textForeign body aspiration (FBA) into the airways is a potentially life-threatening event, and more frequent in children younger than 3 years of age; it can mimic other diseases by its frequently non-specific clinical and radiological presentation. The commonest misdiagnoses in children are asthma and recurrent respiratory tract infections with wheezing. This often makes it particularly difficult for a timely and proper diagnosis, especially when there is a silent history of FBA (not a rare occurrence in the age group at highest risk). We report a case of a 2-year-old boy who arrived at the emergency department at the Hospital of Ferrara, with dyspnoea, fever and wheezing, which had started 12 h after aspiration of a pistachio. The asymptomatic period after the pistachio aspiration, a history of recurrent wheezing during respiratory infections and the non-specificity of clinical and radiological findings, delayed the right diagnosis of FBA
UNUSUAL PRESENTATION OF HENOCH SCHOENLEIN PURPURA
No full textHenoch Schoenlein Purpura (HSP) is the most common
vasculitis of childhood, which involves small vessels most frequently
in the skin, the gastrointestinal tract, the kidney, and
the joints. Palpable non-thrombocytopenic purpura is the essential
element in the diagnosis of HSP.
We report on a child presenting with unusual cutaneous
lesions and high fever. Main differential diagnosis and peculiar
presentations of the disease are discussed
Una rettocolite "difficile"
No full textViene esposto un caso clinico di rettocolite in età pediatrica, interessante sia per la gravità che per la precosità del quadro clinico (la RCU ha un esordio tipico in età adolescente-adulta; i casi in età pediatric, specialmente nei lattanti e durante la prima infanzia, sono invece rari e in genere a prognosi più severa), sia per l'elevato numero di recidive presentate in un lasso di tempo relativamente breve
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
