KELOIDS: COMBINED THERAPEUTIC SOLUTIONS
No full textKeloids are, pathological painful scars, prominent and proliferating beyond the original wound shape, which recur after surgical excision. Their aetiology is much debated, and many hypotheses have been put forward. No single known cause exists, but many factors that modify and increase the normal wound-healing process have been considered as probably involved in the genesis of keloids; for this reason many different therapeutic approaches directed towards each of the causing factors are used.
Methods. Considering the different therapeutic strategies and the physiopathological mechanisms they contrast, we found the most promising solution in the association of surgery, postoperative radiotherapy and compressive dressings with silicone gel sheeting.
Results. Seven out of 11 keloids (9 patients) treated in this way did not recur after an observation period of 2 months - 3 years; 1 patient developed a hypertrophic scar 18 months after surgery, that underwent regression after a 3-month treatment with silicone gel sheeting; 3 keloids recurred 3-5 months after their excision.
Conclusion. Considering the results obtained in this limited number of patients, we believe that the association of surgery, radiotherapy and compressive silicone dressings represents a possible combined treatment modality that deserves some consideration, and that needs to be verified on greater populations in further studie
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
Abductor digiti minimi opponensplasty and flexor digitorum superficialis opposition transfer: What are the main indications? A literature review
No full textThumb hypoplasia is a rare deformity of the hand. Type II and IIIA are the main indications for opponensplasty, together with thumbs with a residual weak opposition after pollicization. Our study operates a review of the current literature to establish which opponensplasty technique is the most appropriate for each patient. We conducted a systematic search using PubMed, Embase, and Web of Science databases. The keywords used were “thumb hypoplasia,” AND “opponensplasty,” “abductor digiti minimi opponensplasty,” “thumb hypoplasia,” AND “abductor digiti minimi,” “opponensplasty,” AND “hypoplasia,” “flexor superficialis opponensplasty,” “flexor digitorum superficialis opponensplasty.” A minimum of 1 year of follow-up was required for inclusion. A total of 222 studies were recovered, of which only 9 articles satisfied our inclusion criteria. From the results obtained, the choice between abductor digiti minimi opponensplasty and flexor digitorum superficialis transfer should depend on the severity of the deformity and the main goal that should be achieved. Children with type IIIA hypoplasia characterized by more unstable joints should undergo flexor digitorum superficialis transfer to restore joint stability. On the contrary, when the instability is not of great concern, abductor digiti minimi opponensplasty, which aims at better defining the thenar eminence and restoring a better global hand function, should be preferred
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
