A clinical analysis of a group of Down's patients [Analisi clinica di un gruppo di pazienti Down.]
No full textThe authors report their experience of the clinical analysis of 40 handicapped subjects: 28 suffered from various degrees of mental handicap and 12 had Down's syndrome. In particular, the authors focused their attention on anomalies of the stomatognathic apparatus in Down subjects, and examined and compared all those factors which are normally attributed to this pathology. An analysis of these findings shows a heterogeneity of clinical conditions which is not revealed in the literature. In the light of these new experiences, before applying pre-programmed protocols in Down's patients it is important to carry out a careful control of their dental, muscular and functional situation together with the prospects for growth and development

No full textTwo cases of severe alkaline esophagitis following total gastrectomy, respectively for a gastric sarcoma and a gastric carcinoma, are reported. In the first case digestive continuity was assured through an Omega loop esophagojejunostomy, while in the second one an esophagojejunostomy according to the Moricca technique was performed. Both patients underwent reoperation and a conversion in Roux-en-Y esophagojejunostomy resolved the reflux related problems. The Authors, therefore, confirm Roux-en-Y esophagojejunostomy as the procedure of choice in preventing and curing esophagitis, which can seriously affect the quality of life and nutritional status of gastrectomized patients
Long-term result after rubber band ligation for haemorrhoids
No full textPurpose: Rubber band ligation (RBL) is a well-known and recognised outpatient procedure utilised for the treatment of symptomatic internal haemorrhoids. This paper describes a retrospective study which analyses the short- and long-term results of a personal series of patients. Materials and methods: A consecutive group of 206 patients with symptomatic internal second- and third-degree haemorrhoids were treated with RBL as outpatients from 1982 to 1989. Two or three piles were legated in a single session. All patients were systematically visited after 1 month and 1 year. Respectively after 10 and 17 years, all the patients were contacted to obtain a telephone follow-up. Results: The short-term follow-up at 1 month and at 1 year showed that 46% of the patients experienced moderate anal pain for 24 h post procedure. Two patients had severe pain (1%) and were admitted in the hospital to be submitted to an operative haemorrhoidectomy within a few days. Only 2.4% of the patients experienced rectal bleeding after a week, and 20% had a second session of RBL after 1 month. At 1 year follow-up, 90% of the patients with second-degree piles and 75% of patients with third-degree piles reported no residual symptoms. The long-term telephone follow-up at 10 and 17 years collected the history of 138 patients (67%). A group of 69% was asymptomatic, 28% had residual symptoms, and 3% needed further surgery. Conclusion: RBL is a safe and effective treatment for symptomatic internal haemorrhoids. Our long-term follow-up demonstrated good long-term results for internal second- and third-degree haemorrhoids. © Springer-Verlag 2009
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
