The Impact of Professional Oral Hygiene in Orthognathic Surgery
No full textIntroduction: Oral hygiene represents a fundamental element with regard to outcomes in oral and maxillofacial surgery. Both basic hygiene that the patient must perform daily at home and obviously professional hygiene aimed at preventing any complications in the surgical field. Methods: Patients undergoing orthognathic surgery in our Department of Maxillofacial Surgery in Ancona, in a total number of 137 in the period studied (2016-2021), were divided into 2 groups: period 1, (2016-2018) and period 2 (2019-2021). The division into 2 groups derives from the establishment of a professional oral hygiene protocol established starting from January 2019 and put into practice by dental hygienists. The protocol consists of preoperative counseling and above all very precise instructions in the postoperative so as to optimize the oral hygiene process, assist in the best possible wound healing and reduce possible postoperative complications. Anamnestic, cephalometric data, measurements of the distances between certain landmarks for the evaluation of facial edema, patient-referred pain, accurate intraoral and extraoral physical examination both pre and postoperative, and complications were collected for each patient. Conclusions: The main goal of the study authors set is to evaluate the effective impact of professional oral hygiene in the pre and postoperative management of patients undergoing orthognathic surgery, taking into account parameters, such as facial edema and pain, and using evaluation scales, making a comparison with the data reported in the 3 years before and after the establishment of the protocol applied by the authors
Synchronous bilateral Warthin's tumours of the parotid glands: a case report
No full textWarthin's tumour is the most frequent monomorphic adenoma of the major salivary glands, representing about 2-15% of all parotid tumours. Most of the multifocal Warthin's tumours are unilateral, whereas bilateral Warthin's tumours are far less common; bilateral Warthin's tumours are metachronous with few synchronous cases having been described in the literature. The Authors present an interesting case of simultaneously occurring bilateral Warthin's tumours growing in the parotid glands
New Tunneled Buccal Fat Pad Flap for Palatal Reconstruction
No full textIn the palatal defects due to surgical resection, flap selection is very important for a correct reconstruction. Different methods have been suggested over the time, however the pedicled buccal fat pad is a simple, effective, reliable flap for reconstruction after palate tumor resection. The aim of the present study is to introduce a new surgical technique for palate reconstruction with pedicled buccal fat pad flap exposing the advantages. The Authors performed this procedure in 17 patients in order to treat medium-sized oncologic surgical defect of palate region in the period between 2016 and 2019. Complete wound healing after only 4 weeks without complication after 12 months follow-up was observed. This is the first cases series described with this new technique
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
