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
Abdominoplasty as a reconstructive surgical treatment of necrotising fasciitis of the abdominal wall
No full textObjectives: Necrotising fasciitis (NF) is a potentially fatal, uncommon infection of the soft tissue with rapid progression. This article presents one case of NF of the abdomen wall, describing the presentation, diagnosis and long-term successful treatment. Methods: The defect of the abdominal wall was treated with medical support (antibiotics broad-spectrum coverage), V.A.C. therapy and plastic surgery procedures. Results: The coverage of the abdominal wall defect has been achieved by abdominoplasty-type advancement flaps in one step with the preservation of the umbilicus. One month after the surgical procedure, the patient returned to a normal lifestyle with a good quality of life. Conclusion: The success of this case should be attributed to an early diagnosis, aggressive debridement and a good intensive medical management; these elements are essential to a better prognosis for NF
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
STUDIO COMPARATIVO RANDOMIZZATO A DOPPIO CIECO SULL'EFFICACIA DI DUE ACIDI IALURONICI CROSS-LINKED, RESTILANE E PURAGEN, NEL TRATTAMENTO DEI SOLCHI NASO-LABIALI
No full textDERMOSCOPIA DIGITALE IN EPILUMINESCENZA ESEGUITA DA MEDICI DI BASE SU LESIONI CUTANEE PIGMENTATE: UTILITA' DELL TELEDIAGNOSI
No full textLa dermoscopia digitale è un efficace strumento d’indagine per lo studio delle neoformazioni cutanee pigmentate (NCP), basata sull’analisi di immagini digitali ad alta risoluzione.
È stata verificata l'utilità della dermoscopia digitale su NCP, facendo effettuare la suddetta indagine da medici di base e valutando l’efficacia e la sicurezza del metodo tramite l’invio delle immagini digitali all’U.O. di Chirurgia Plastica di Siena.
E’ stato chiesto ad alcuni medici di base del territorio di valutare NCP come “benigne” o “sospette”, tramite informazioni anamnestiche ed esame clinico e poi tramite dermoscopia. Le immagini digitali acquisite (235 lesioni in 197 pazienti) sono poi state trasmesse, tramite e-mail, all’U.O. di Chirurgia Plastica di Siena, e giudicate dai medici del centro di riferimento come “da controllare” (219 lesioni) o “da asportare” (16 lesioni).
L’indagine dermoscopica ha permesso di ridurre il numero di lesioni sospette per neoplasia maligna da 68 a 29 e, dopo telediagnosi, da 29 a 16. Sono state asportate 16 lesioni, di cui 15 facenti parte del gruppo catalogato come lesioni sospette dai medici di base ed una catalogata come “benigna” (un falso negativo). L’esame istologico ha messo in evidenza 5 melanomi (2 in situ), 10 nevi displastici ed un basalioma pigmentato.
La dermoscopia e la telediagnosi hanno permesso di ridurre del 76.5% il numero delle exeresi (da 68 a 16), evitando ai pazienti di effettuare una valutazione clinica diretta con lo specialista. L’esame dermoscopico effettuato dai medici di base, dopo un’accurata fase di preparazione, ha permesso di ridurre del 57.3% le lesioni considerate “sospette” (da 68 a 29), rispetto alla sola valutazione clinica. La dermoscopia migliora l’accuratezza diagnostica su NCP e, se adottato dai medici di base unitamente alla telediagnosi, può ridurre considerevolmente la percentuale di errori, il ritardo della diagnosi e l’invio di pazienti allo specialista o ai centri di riferimento
