Subungual nodular lesion of the big toe of the right foot.
No full textTeenager, male, soccer player reports the presence of an hard nodular lesion at the big toe of his right foot. The lesion has had a slow growth and only in the last few months the patient reports pain in pressure and by walking. Before the surgery we required an x-ray that has confirmed the clinical suspicion of a subungual exostosis.
After troncular anesthesia at the base of the hallux and the application of a tourniquet, we cut the peri-lesional skin progressing in a distal-proximal direction and progressively separate the nail bed from the underlying bone until to raise and to bend the nail bed and the nail plate in order to more easily treat the exostosis. We then used bone surgical instruments to eliminate exostosis. Finally the surgical wound was treated with hemostatic sponge that we covered with the bed and the nail plate repositioned and fixed in their natural seat with sutures
Looking for an EASY REMOVAL of the "DONATI" stitch.
No full textThe removal of the Donati stitch can be difficult especially when the suture has been kept in place for too many days. The risk is to not completely remove the non re-absorbable thread which can cause a foreign body granuloma and promote a bacterial infection.
A simpler method has been found to deal with the aforementioned problem, starting from the use of the thread, passing to that of the cotton cylinder until reaching a small silicone tube ..
Nodular lesion of the right helix (exeresis + transposition flap)
No full textPatient with keratotic nodular lesion of the right helix, about 1 cm in diameter, grown in a few months. Among the various therapeutic options we chose the surgical exeresis with histological examination. The surgical wound could not be closed with direct suture and instead of the usual free skin graft we used a flap of proximity. Among these, what seemed most suitable in relation also to a great laxity of the skin of the retroauricular furrow, was a transposition flap
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
