Granulomatous cheilitis: Differential diagnosis in patients with macrocheilia
No full textMacrocheilia, or lip enlargement, has a varied aetiology, but granulomatous conditions, both infective and non-infective, comprise a significant proportion of patients. Diagnosis starts with clinical investigations while histological examination is required for a definitive diagnosis. In the case presented, a young man presented with painless swelling of upper lip over the past 3 months. Given the clinical history and biopsy results, the diagnosis of granulomatous cheilitis was made which is considered a rare manifestation of metastatic Crohn's disease. Treatment options remain debated, though in the situation presented a conservative approach was adopted, consisting of antibiotics and corticosteroid therapy, which resulted in significant remission in lip swelling without recurrence after a 3-month follow-up
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
A rare mandibular neoplasm: case report of a Central Giant Cell Granuloma
No full textLa mandibola può essere interessata da una grande varietà di neoformazioni, ad esempio: cisti ossea aneurismatica, mixoma odontogeno, CGCG (granuloma a cellule giganti centrali), GCT (tumore a cellule giganti), sarcoma, ameloblastoma, linfoma, fibroma ossificante, mixoma odontogeno, granulomi, malformazioni arterovenose e Schwannoma. Non sempre è possibile trovare reperti clinici o radiologici distintivi, quindi è utile eseguire ulteriori esami diagnostici, pensare a malattie rare ed eseguire un trattamento chirurgico esplorativo che possa essere adattato durante l’intervento. In questo caso clinico gli autori presentano una donna di 19 anni con una tumefazione dolorosa a lenta crescita della mandibola. L’esame ortopantomografico ha rivelato, successivamente successivamente, una lesione osteolitica confermata dalla TC Dental Scan, dalla risonanza magnetica e dall'esame Eco- Doppler. Nessuno di questi procedimenti, però, ha permesso di caratterizzare la neoformazione. Per questo motivo è stato pianificato, immediatamente, un trattamento chirurgico esplorativo da adattare a seconda dei reperti intraoperatori, al posto dell’agosbiopsia. Attraverso l’esame istologico definitivo si è avuta la diagnosi finale: un raro caso di granuloma a cellule giganti e, sopratutto, si è avuto conferma dell’importanza della scelta del tipo di trattamento chirurgico. Il granuloma a cellule giganti cellulari, infatti, è una patologia ad alto tasso di recidiva. Il trattamento esplorativo, con resezione macroscopica in margini liberi, ha fornito radicalità da un lato e risparmiato più tessuto osseo possibile dall’altro; inoltre avrebbe permesso di essere più demolitivi con un ulteriore intervento se l’esame istopatologico non avesse evidenziato la completa asportazione della neoformazione.Mandible can be affected by a great variety of neoformations, like aneurysmal bone cyst, odontogenic myxoma, CGCG (Central Giant Cell Granuloma), GCT (giant cell tumor), sarcoma, ameloblastoma, lymphoma, ossifyng fibroma, odontogenic mixoma, granuloma, arteriovenous malformations and Schwannoma. Occasionally is not possible to find clinical or radiological distinctive findings so is usefull to perform additional exams, think about rare disease and perform an explorative surgical treatment which can be adapted to the intraoperatory findings. This attitude may help to reduce overtreatment but also to be radical especially in case of rare condition like the case presented: a Central Giant Cell Granuloma of the jaws. In this case report the authors present a 19-year-old female with a slowly enlarging, painfull swelling on the left side of the lower jaw. Ortopantomography exam revealed an osteolytic bone formation confirmed by Tomographic Dental Scan, MRI and Eco-Doppler exam. No one of these procedures, however, allowed to characterize the neoformation. For that reason was planned immediately an explorative surgical treatment, instead of an agosbiopsy. Macroscopic free margins resection provided radicality on one side and saved much bone tissue as possible on the other; morever it would have permitted to be more demolitive with a further procedure if the histopathological examination of specimen didn't show complete neoformation removal.

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
