Atopy: pediatric ENT manifestations in children
No full textAbstract
OBJECTIVE: The aim of the present study is to discuss the basics of atopy in children in relationship to the principal ENT allergic disorders such as allergic rhinitis, rhinosinusitis and their impact on lower airways, allergic otitis media, and oral cavity focusing on their natural history.
METHODS: An updated and exhaustive review of principal literature on these topics is performed, underlining the constant but growing interest evoked by these disorders most of all the possible sequelae or complications. Considering the different districts which can be selectively or simultaneously affected by the allergic sensitisation, diagnosis can be a really hard task; in this paper, we tried to draw an integrated diagnostic approach to atopic children and some guidelines for a correct therapeutic approach.
CONCLUSIONS: Atopic disorders could expose young patients to years of chronic diseases that interferes with their development and with many important aspects of their lives. For these reasons, and considering the high social and medical costs of this disease, it is extremely important to adequately treat allergic pathologies from the early phases of its natural history. Moreover, we cannot forget that an appropriate therapy of allergic pathologies should not be only able to decrease symptoms but, it should also be able to improve patients health related quality of life
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
Clinical guideline on adenotonsillectomy: the italian experience
No full textFive years after publishing the document on 'The clinical and organizational appropriateness of tonsillectomy and adenoidectomy' in 2003, a multidisciplinary group of experts came together again to update this document and to publish a guideline with grading of evidences and recommendations. Major revisions of the previous document were addressed to: (1) the diagnosis and indications for adenotonsillectomy in presence of OSAS in children, (2) the analysis of advantages of new surgical techniques in terms of effectiveness, costs or the risk of postsurgery bleeding and recurrences, and (3) the efficacy of perioperative management in reducing the incidence and duration of post-operative events. In fact, in the last years, a relevant number of evidence became available on the above-mentioned items making the need for a continuing updating of guidelines tangible. As a premise to the guideline, it is stressed how the previous document impact was prominent: the decrease of total number of tonsillectomy in Italy was evident and accompanied by a decrease of variations in the regional rates. Besides the document contributed to strengthen the multidisciplinary collaboration, especially between pediatricians and otorhinolaryngologists, and to divulge the Evidence-Based Medicine culture
Cervical neoplastic lymphadenectomy in carotid artery invasion
No full textThe Vascular Surgery has seen a significant enlargement procedures available and also the invasiveness of the interventions with considerable benefits for patients, even during urgency or emergency situations that may occur during procedures of other specialists.
The collaboration between the different disciplines and planning procedures to be adopted are among the most important principles that reduce the risk and can ensure the best results in a university hospital with a high volume of interventions.
The skilled Vascular Surgeons and other expert leaders whit large experience describe diagnostic, clinical and treatment of complications, according to modern developments that we have seen over the last decade with conventional methods and, more often, endovascular techniques
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
