L’impiego delle lenti a contatto terapeutiche per il trattamento delle ulcere corneali indolenti del cane: esperienza personale
No full textRIASSUNTO Le lenti a contatto morbide gas-permeabili rappresentano una delle opzioni terapeutiche per il trattamento dell’ulcera corneale indolente del cane. Gli Autori prendono in esame vantaggi e svantaggi dell’applicazione delle lenti, valutando i risultati ottenuti in 16 cani trattati con questa tecnica. Tutti i pazienti sono stati preventivamente sottoposti a debridement corneale e durante la permanenza della lente hanno ricevuto antibiotici e midriatici-cicloplegici topici. La lente è rimasta in situ in 14 dei 16 soggetti, determinando velocemente (in media 9,86 giorni) la guarigione della lesione corneale con esiti cicatriziali minimi. In uno dei due casi in cui si è avuta perdita della lente, si è provveduto alla sua riapplicazione dopo 48 ore, con guarigione dell’ulcera entro 12 giorni. La lente a contatto rappresenta quindi un’ottima opzione terapeutica di primo approccio dell’ulcera indolente del cane, soprattutto in virtù della sua efficacia e facilità di applicazione. SUMMARY Soft contact lenses (SCL) are an available method for indolent ulcers treatment in dog. Indolent ulcers are a common and often frustrating problem in clinical ophthalmology; these lesions can be observed in any breed of dog, although boxers appear predisposed. Indolent ulcer, also called persistent corneal erosion, is a primary lesions of the cornea. Many tecniques have been described to encourage healing of persistent erosions, but none are consistently effective. This study evaluate the use of SCL as protective bendage in the treatment of indolent ulcers in dog. Sixteen dogs with persistent corneal erosion were evaluated for healing in response to application of SCL. In our study we included only dogs with primary corneal erosion. These dogs ranged in age from 7 to 14 years, with an average age of 10.5 years. They also differed in breed, sex and size. Prior to insertion of SCL, all the sixteen dogs were treated with corneal epithelium debridement; the corneas were debrided with a sterile cotton swab under topical anesthesia. Fourteen erosions healed within 9.86 days. In one of the two cases who lost the lens, we proceeded with a new insertion after 48 hours; in this case the erosion healed in twelve days. This study suggests that SCL is a valuable treatment option in management of indolent ulcers in dog

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
