Conservative management of chronic ankle instability.
Chronic ankle instability is a significant cause of morbidity. There are well-documented and effective surgical options for managing this condition. However, conservative management can be a viable option in selected patients. Failure of conservative management can be an indication for surgery if morbidity warrants it. Surgery can be delayed without necessarily affecting outcome
Tailor's bunion: a review.
The tailor's bunion is a painful bony prominence on the lateral aspect of the fifth metatarsal head that occurs in many individuals, but seldom causes symptoms. This article reviews the current literature regarding the presentation, etiology, and management of the tailor's bunion. The first line of management should be conservative, with advice on shoe wear. Orthotics may be useful if a symptomatic tailor's bunion results from excessive subtalar joint pronation. Operative management, indicated when symptoms are not controlled nonoperatively, aims to decrease foot width and the prominence of the tailor's bunion. Procedures can be grouped into resections and distal, diaphyseal, and proximal osteotomies. A distal osteotomy is recommended if medial translation of the head for one-third of the width of the metatarsal shaft produces a normal fourth-fifth intermetatarsal angle. A proximal osteotomy can be performed in the face of larger deformities. The management of recurrent tailor's bunion is still controversial. If the recurrence is due to under-correction, or if the initial procedure was not the best suited to that particular patient, then revision surgery may be helpful, after the cause of the failure has been established. Although unpopular, resection should be considered as the final salvage procedure
Anatomic repair for chronic lateral ankle instability.
Symptomatic ankle instability will develop in upto 20% of patients after inversion injury. Although most patients can be successfully managed with rehabilitation and bracing, some will continue to suffer recurrent ankle instability with activities of daily living, work on uneven terrain, or sports. For this group of patients, we advocate direct anatomic surgical repair with the Brostrom procedure with or without its modifications
Chronic rupture of tendo Achillis.
The Achilles tendon is the most commonly ruptured tendon in the human body. About 20% of complete ruptures of the Achilles tendon are diagnosed late. The management of chronic ruptures of tendo Achillis is usually different from that of acute rupture, as the tendon ends normally will have retracted. As clinical diagnosis of chronic ruptures can be problematic, imaging can be useful. Most investigators counsel operative management, and the possibility of undertaking a tendon transfer should be kept in mind. Local tendons, such as the flexor digitorum longus, the flexor hallucis longus, and the tendon of peroneus brevis, can be used, and some investigators have reported the use of a free gracilis tendon graft. Allografts and synthetic grafts are also employed. There are no comparative studies and no randomized controlled trials to guide clinicians toward an evidence-based approach to management
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
