No full textProximal forearm fractures: our clinical experience.
No full textForearm traumas are frequent and sometimes complex; soft tissue damages associated with bone lesions could be understimated and so compromise the final result, in spite of a good reduction and osteosynthesis.
Articular and iuxta-articular proximal radius and ulna fractures, which can be associated to radio-humeral dislocations in Monteggia lesions, are less frequent compared to diaphyseal fractures and can present a lot of therapeutical difficulties and a high rate of complications.
These complications are avoided and reduced if the treatment is quick and focused on stable osteosynthesis and anatomical reduction of the fragments of the fracture and followed, as soon as possible, by rehabilitation.
The authors present the 10 years experience of Parma Orthopaedics Institute with a follow-up of at least 12 months
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
The four-strand staggered suture for flexor tendon repair: in vitro biomechanical study.
No full textPurpose To assess in vitro biomechanical properties of a 4-strand flexor tendon suture
compared to 3 established suture techniques. This technique, which is made of 2 alternating
and staggered sutures, one external to the tendon and the other internal, must be sufficiently
resistant to withstand loads applied by modern, early active mobilization protocols.
Methods Forty flexor hallucis longus tendons were harvested from fresh cadavers, cut, and
repaired using 4 different suture techniques (Strickland, Wolfe, modified Savage, and a new
technique called 4-strand staggered). All repaired tendons were submitted to static loading
trials to measure gap formation (2 mm) in relation to tensile force and breaking force of all
4 sutures. Twenty additional tendons were repaired with the new suture technique and
submitted to dynamic trials under cyclic loading.
Results The 4-strand staggered suture technique proved to be statistically superior to Strickland
and modified Savage techniques following the static loading trials for gap formation and
breaking force. This technique is statistically superior to the Wolfe cruciate suture for
breaking force and superior but not statistically significant for gap formation. The dynamic
loading trials have shown that the 4-strand staggered suture can tolerate in vitro loads similar
to those exerted by modern, early active mobilization protocols.
Conclusions The suture technique created by the authors proved to hold superior biomechanical
properties than the other techniques tested in this study and might be suitable for early
active mobilization protocols
