Sindrome di Hay-Wells. presentazione del primo caso italiano.
No full textThe Authors report the first Italian case of Hay- Wells syndrome. This girl shows the typical findings of AEC syndrome:
ankyloblepharon, ectodermal dysplasia and cleft lip with cleftpalate.
The phenotypic spectrum of the syndrome and the differential diagnosis are discussed
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
Pericardial effusion from central venous catheter in a newborn: Survival after early echocardiographic diagnosis
No full textA case of late pericardial effusion by central venous catheter in an infant in parenteral nutrition is reported. The infant (69 days old, 17 days from catheter placement) suddenly presented severe polipnea and tachicardia. Immediate echocardiography confirmed the presence of pericardial effusion and therapeutic pericardiocentesis was immediately performed. Following pericardiocentesis the infant s condition quickly improved and afterwards infusion of parenteral nutrition was also resumed without any further problems. Although a rare occurrence, we think pericardial effusion should be always suspected in any patient with a central venous catheter whose conditions deteriorate suddenly and in our opinion, these symptoms require an immediate echocardiography
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
Vascular access in patients affected by short bowel syndrome
No full textThe aim of this study was to evaluate the problems induced by the use of a central venous catheter (CVC) in a series of patients with short bowel syndrome observed at the university of Padua (Italy) between January 1981 and June 1997. During this period, 14 patients required central venous access for parenteral nutrition (PN); 55 catheters were inserted, 6 with percutaneous and 49 with surgical techniques. We divided the patients into two groups according to PN duration. The first group includes 11 children with short/medium-term PN 8 are now eating, and 3 died from respiratory failure) while the second group includes 3 patients on home long-term PN. Thirteen catheters were placed in the first group, and the mean PN duration was 173 days; the three patients on home PN required 42 catheters. It is our experience that the use of catehters in patients requiring short/medium- term PN is a safe procedure with few complications; patients on home long-term PN present an increasing number of complications, and the vascular access could become a serious problem as the number of PN-dependent increase
Hepatic abscess and umbilical venous catheter: one cannot be cavalier about proper position
No full textPURPOSE The umbilical venous catheter (UVC) is routinely used in neonatal intensive care. Incorrect placement may expose the patient to some dangerous complications (i.e. thrombosis, abscesses, etc). We report a case of an hepatic abscess due to incorrect positioning of this device. We describe how the abscess was treated and we emphasize that one cannot be cavalier about proper positioning of the UV
