Applicazione delle tecniche di rimodellamento mammario alla mastoplastica riduttiva a peduncolo superomediale: la nostra esperienza in ambito ricostruttivo ed estetico
Full text linkLa mastoplastica riduttiva è uno degli interventi più eseguiti in chirurgia plastica, il cui obiettivo è non solo
la riduzione delle dimensioni mammarie, ma la creazione di una forma piacevole, rispettandone, ove
possibile, sensibilità e funzione. Nel corso degli anni, sono state descritte varie tecniche chirurgiche, comprendenti diversi peduncoli porta-complesso areola capezzolo e pattern di resezione cutanea, ognuno dei quali presenta indicazioni e limiti propri. Da ciò, ne consegue la necessità non solo di adottare una
tecnica dal buon risultato estetico, ma che consenta una stabilità nel tempo dello stesso, evitando il ricorso ad interventi secondari. A tale scopo sono stati descritti diversi approcci chirurgici, quali suture di sospensione, lembi parenchimali, fionde muscolari, tecniche di rimodellamento e resezione parenchimale. Il presente progetto di ricerca nasce dall’ applicazione dei principi del rimodellamento mammario alla mastoplastica riduttiva a peduncolo superomediale. Ciò ha condotto allo sviluppo di una tecnica chirurgica, chiamata “lembo ad amaca”, che deriva dalla combinazione della mastoplastica riduttiva a peduncolo superomediale con un lembo dermoadipoghiandolare di avanzamento VY, scolpito sui quadranti mammari inferiori. Esso consente una migliore definizione dei poli mammari inferiori e del solco sottomammario, sostiene il peduncolo, migliora la forma globale della mammella. Inoltre, è di facile esecuzione, versatile e ben riproducibile, potendo costituire un utile strumento aggiuntivo nell’ armamentario chirurgico. Tale procedura è stata eseguita da Febbraio a Settembre 2017, in 10 pazienti, per finalità estetiche e ricostruttive. I risultati estetici ottenuti e il grado di soddisfazione sono molto promettenti, costituendo le basi per uno studio più ampio che consenta di analizzarne meglio le caratteristiche.Breast reduction is one of the most frequent procedure in plastic surgery. The goal is not only reduce breast
size, but create a pleasing shape, preserving, if possible sensation and function. Over the years, many approaches have been described, including various type of dermoglandular pedicles and skin resection
patterns, all of which have their indications and limits. It is therefore necessary to adopt not only a technique
with good aesthetic results, but long-lasting one, minimizing the revisional surgery. Many surgical
approaches have been described for this purpose, such as suspension type sutures, parenchymal flaps, muscular slings, parenchymal reshaping and resection. This research project was born from the application of breast reshaping principles to superomedial pedicle breast reduction. This led to the development of a
surgical technique, called “hammock flap”, which is a combination of superomedial pedicle breast reduction and V-Y inferior advancement flap. This tissutal rearrangement allows a better definition of lower breast pole and inframammary fold, supports the pedicle in its position and improve the overall breast shape. Moreover, it’ s easy to perform, versatile and reproducible; it may be a useful surgical additional
tool. From February to September 2017, 10 patients were undergone to this procedure for aesthetic and reconstructive purposes. The aesthetic outcomes and patients’ satisfaction are promising and constitute the basis for a large trial to better analyse its features

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
