Current trends and innovations in oral and maxillofacial surgery
No full textObjectives: This manuscript reviews advancements in oral and maxillofacial surgery, encompassing minimally invasive techniques, innovations in implant dentistry, regenerative medicine, innovations in temporomandibular joint, and novel methodologies in salivary gland surgery. Methods: A comprehensive analysis of recent developments in the field is presented, focusing on the integration of new technologies and biological therapies. Emphasis is placed on minimally invasive procedures, virtual surgical planning with CAD/CAM and 3D printing, implant design and placement innovations, and regenerative approaches. Results: Minimally invasive procedures, often employing endoscopic or robotic assistance, reduce surgical morbidity and accelerate patient recovery. Virtual surgical planning and 3D printing enhance pre-surgical accuracy. Innovations in implant design, surface modification, and guided surgery improve prosthetic outcomes. Regenerative medicine and tissue engineering, including the use of growth factors and stem cells, offer new options for tissue restoration. In temporomandibular joint disorders, these strategies aim to improve function and reduce reliance on arthroplasty. The use of superficial dermal substitutes in salivary gland surgery reduces complications such as Frey syndrome. Conclusions: These advancements reflect a paradigm shift in oral and maxillofacial surgery, enhancing patient care and expanding the field's potential through precision, biologically based therapies, and less invasive approaches
Synovial chondromatosis of the temporomandibular joint with glenoid fossa erosion: disk preservation for early anatomical recovery
No full textBackground: Synovial chondromatosis (SC) of temporo- mandibular joint is a pseudoneoplastic condition characterized by benign cartilaginous metaplasia of mesenchymal residues of synovial tissue with intra articular nodules formation. TMJ involvement is rare. Interposition of loose bodies in the intra- articular space generates a pressure that could lead to glenoid fossa erosion with intracranial extension.
Findings: The aim of the study is to present 5 SC cases with intracranial extension approached with articular disk preservation. Methods: Five patients treated from 2009 to 2018, affected by TMJ chondromatosis with intracranial extension were included. Results were compared with literature. Inclusion criteria were: CT showing glenoid fossa erosion, MRI, histological SC confir- mation, and a 2-year-follow-up. Access to superior compartment was obtained. Surgical treatment was performed removing care- fully the mass and preserving articular disk. Medial region was investigated with arthroscopy.
Findings: A 2-years-follow-up showed no swelling and pain. Patients showed a good mouth opening recovery and improvement of previous mouth limitation. Morphological study, performed through MRI and CT, showed complete anatomical TMJ recovery and total bone reconstruction of the glenoid fossa.
Conclusion: The only removal of intra articular nodules, with TMJ arthroplasty and articular disk preservation, represents a valid treatment proposal for anatomic and functional full recovery in synovial chondromatosis of the temporomandibular joint with glenoid fossa erosion
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
