Free levator complex recession in Graves' ophthalmopathy. Our experience
No full textThe use of scleral graft has been suggested in patients with upper lid retraction due to thyroid ophthalmopathy to correct severe cases and to avoid unpredictable results. But this technique is more complicated than others and more time-consuming. The authors have used a free recession technique to deal with the functional and cosmetic problems of these patients. The results of a group of 60 patients (98 eyes) with Graves' ophthalmopathy who were referred to their institute over the last ten years and underwent eyelid surgery were evaluated. Free recession surgery achieved good results in 75% of all cases after one procedure. In spite of careful preoperative evaluation the remaining patients needed additional surgery to achieve a good final result. However, in some cases the outcome of the surgery in upper lid retraction remains unpredictable
Progression of Lactobacillus plantarum prosthetic valve endocarditis followed by transesophageal echocardiogram
No full textEndocarditis due to Lactobacillus species is extremely rare. We report an uncommon case of Lactobacillus plantarum bioprosthetic aortic valve endocarditis, presenting with severe aortic steno-regurgitation, which responded to conventional medical and surgical treatment. This case provides a better understanding of the disease process of L. plantarum and highlights the role of transesophageal echocardiography in following the entire course of endocarditis.

Centri di Patologia Orbitaria: distribuzione sul territorio e prospettive
No full textObiettivo di questo lavoro è stato quello di valutare l'incidenza dei casi affetti da Patologia Orbitaria e l'eventuale variazione negli ultimi anni, e stabilire se questi dati giustificano l'esistenza di un centro specializzato per la diagnosi, la cura e lo studio di queste malattie. Scopo dello studio sarà anche quello di riportare il numero di morti causati dai tumori orbitari e il numero di pazienti con perdita della funzione visiva causate da lesioni orbitarie.
Studio retrospettivo basato su una serie di casi affetti da malattie dell'orbita registrati in un singolo centro in un periodo di 26 anni.
In questo periodo 4000 casi sono stati osservati provenienti da una area geografica di circa 20000000 abitanti (0,02 incidenza approssimativa). Alcuni tipi di tumori sono aumentati negli ultimi anni, in particolare i linfomi, la cui frequenza si è accresciuta circa il 50%. La mortalità generica causata da una neoformazione orbitaria è risultata essere del 9% e la compromissione della funzione visiva è stata del 7%.
Il numero di pazienti esaminato è sufficiente per concludere che la Patologia Orbitaria ha un importante impatto sociale sia per quel che concerne il rischio di vita, sia per il rischio di compromissione della funzione visiva. Per migliorare la conoscenza e il trattamento delle malattie orbitarie è utile la presenza di un centro specializzato ogni 20 milioni di abitanti circa
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
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
