Il carcinoma squamocellulare oculare nel cavallo: attualita' in terapia e casistica clinica.OCULAR SQUAMOUS CELL CARCINOMA IN HORSES: TREATMENTS AND CLINICAL CASES
No full textSCC is the most common neoplasm that affecting the eye and the periocular tissues in horses. During the last years several options have been described in order to increase the efficacy of the therapy. Most of these studies have been made in United States and Australia, in areas where the SCC is more common. No data can be found in our country. We report 16 cases of SCC collected in Italian field providing informations about breed, hair colour, gender, age and localizations. The aim of this study is to compare our results with the current therapies described in literature

No full textPharmacological cytoreduction and sliding skin graft (h-plasty) for bilateral lower-eyelid squamous cell carcinoma in a pony
No full textPurpose. To describe the surgical approach to a bilateral lower eyelid squamous cell carcinoma (SCC) in a pony. Methods. A 9 year old mare, Connemara Pony, light hair, presented for a bilateral lower-eyelid infiltrating mass. No diagnostic test was performed and a bilateral SCC was suspected. The neoplasia invaded 50% of the length of the lower-eyelid in both eyes, including the medial cantus in the left one. Because of new promising approaches to SCC (Hyperthermia, Brachytherapy, Photodynamic therapy) as well as most immunotherapy and chemotherapy molecules were not available, palpebral surgery was considered. Due to the size of the lesions, a pre-surgical cytoreduction was performed by using Piroxicam 0,3mg/kg/24 hours PO associated to local application of Imiquimod cream 3 times a week for 3 weeks. Slight reduction of the lateral portion of the mass was noted in both eyes, and surgical approach with H sliding skin graft was performed under general anesthesia. Lower lacrimal punctum in left eye was sacrificed, but the canaliculus was cannulated for one month. Tobramycin ointment was given topically after surgery q 6 h OU until healing occurred and systemic antibiotics and non-steroidal antiinflammatory (Flunixin M.) were administered for 7 days. cells. Results. Hystopathology confirmed the diagnosis of bilateral SCC infiltrating lower eyelid and the surgical margins appeared free from neoplastic cells. A normal palpebral function was maintained bilaterally; no recurrence was noticed 2 years after surgery. Conclusions. Whenever a new approach to palpebral SCC is not available, cytoreduction associated to surgery can be considere
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
