Quadriceps tendon tear rupture in healthy patients treated with patellar drilling holes: clinical and ultrasonographic analysis after 36 months of follow-up
Get PDFBackground: quadriceps tendon subcutaneous rupture is an uncommon injury affecting predominantly middle-aged men as a result of direct or indirect trauma; aim of this work is to evaluate clinical outcome and tendon morphology in patients treated surgically with transpatellar drilling suture.
Methods: 20 patients (20 male) with an average age of 54 (42-59) were evaluated with a mean follow-up of 36 months.
Measurements of range of motion (ROM) and of tight circumference were collected. Lysholm and Rougraff Score were also performed.
All the patients underwent a US evaluation the morphologic changes of the repaired tendon.
Results: mean active ROM was 1°-117°; average difference in the circumference of the quadriceps was 2.6% 10 C and 3.3% 15 C. The mean Lysholm Score calculated was 88/100; the mean Rougraff Score 17/25.
At ultrasonographic evaluation all tendons were continuous; heterotopic ossification was present in 18 quadriceps tendons. Thickness was augmented in 18 quadriceps tendons and in 5 patellar tendons.
Vascularization was always conserved. Lateral subluxation of patella was reported in 1 case.
Conclusions: patellar drilling holes repair is a nondemanding procedure, inexpensive and technically uncomplicated.
US evaluation confirms tendon healing; tendon remodeling does not affect patient’s clinical outcome and quality of life
Isolated fractures of the Greater tuberosity in proximal humerus: does the direction of displacement influence functional outcome?
No full textTotal elbow arthroplasty in distal humeral nonunion: Clinical and radiographic evaluation after a minimum follow-up of three years
No full textBackground: Total elbow arthroplasties (TEAs) are usually indicated in chronic inflammatory arthropathies.
This procedure has also recently been used in complex distal humeral fractures and nonunions in
selected patients. This study analyzed the clinical and radiographic outcomes in patients treated for nonunions
around the elbow region with a minimum follow-up of 3 years.
Methods: Between May 2002 and June 2012, 20 patients affected with distal humeral nonunions were
treated with TEA. All patients were assessed clinically using the Mayo Elbow Performance Score and
radiographically to evaluate the positioning of the prosthetic components and signs of loosening. Statistical
analyses were performed to investigate the presence of clinical and radiographic variables as predictive
factors of poor functional outcomes.
Results: The Mayo Elbow Performance Score of the affected arm improved significantly between the
preoperative period and follow-up. Results were good or excellent in 90% of the patients even if a
high rate of complications (30%) was encountered. The development of complications after surgery
and stages II, III, and IV radiolucency, according to the Morrey criteria, were predictive factors of
poor outcomes.
Conclusions: According to the satisfactory results observed in this study, TEA could be indicated in
selected patients aged older than 70 years with low functional demands and affected with distal humeral
nonunions in which obtaining a stable fixation is difficult
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
