Bycicling related urogenital disorders: Huge epididymal cyst and tubular ectasia of rete testis
No full textIndividuals involved in sports are at risk for sustaining various injuries. Musculoskeletal injuries make up the majority of these injuries, and urogenital ones occur more uncommonly. Bicycle riding, which is the most popular means of transportation, recreation, fitness and sports among millions of people of all ages, is also a potential source of acute traumatic injuries as well as overuse injuries, some of them directly affect the urogenital tract. Here, we report a case of huge epididymal cyst (EC) and tubular ectasia of rete testis (TERT) caused by the continuous shock and vibration of the saddle in an amateur on-road cyclist. In this patient, ultrasound (US) allowed for an excellent detection of these scrotal abnormalities, having been able to avoid unnecessary deep insights. We hope that this case presentation will raise the sports physician's awareness of chronic overuse scrotal injuries by cycling. The knowledge of this sports phenomenology is indispensable for correctly diagnose and manage these injuries
BYCICLING RELATED UROGENITAL DISORDERS: HUGE EPIDIDYMAL CYST AND TUBULAR ECTASIA OF RETE TESTIS

We hope that this case presentation will raise the sports physician's awareness of chronic overuse scrotal injuries by cycling. The

Post-operative MRI and US appearance of the Achilles tendons
No full textThe Achilles tendon is one of the most commonly ruptured tendons in the human body. Minimally invasive and open surgical repairs are commonly undertaken to manage acute Achilles ruptures. This article describes the postoperative imaging findings and their evolution after surgery. Ultrasound and magnetic resonance imaging provide crucial information regarding the morphology, structure, vascularization and mobility of the Achilles tendon on the surrounding planes. Morphologically, a repaired tendon is physiologically larger and wider than an intact one, with a loss of its fibrillary structure; the presence of surgical material in the context of the tendon is normal after the rupture has been repaired. After surgery, the tendon is more vascularized in power-Doppler imaging. Elastography and diffusion tensor Imaging are innovative tools which allow for the visualization of microstructural abnormalities not apprehensible using conventional imaging techniques. A treated Achilles tendon is unlikely to regain a normal imaging appearance, and the health care professional must distinguish between postoperative findings and actual pathological features. In this context, clinical examination still reigns supreme
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
Sonographic Evaluation of the Anterolateral Ligament of the Knee: A Cadaveric Study
No full textRotational stability of the knee involves not only the cruciate ligaments but also
another structure named anterolateral ligament (ALL), the function of which is still
controversial. This study evaluated the effectiveness of high-resolution ultrasound (US)
examination to detect the ALL. We studied 8 cadaveric knees (8 ALLs). On each knee,
high-resolution real-time ultrasonography examination was performed by an experienced
musculoskeletal radiologist before and after the procedure, with the surgeons
blind to the results of the scan both before and after dissection. The ALL was identified
in each cadaver limb by the musculoskeletal radiologist. US is a useful imaging modality
to identify and evaluate the ALL. The ability of US to fully evaluate injuries involving the
ALL still needs to be demonstrated in a clinical setting
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
A rare case of Hoffa's fat pad herniation in a young patient: dynamic ultrasound and MRI diagnosis
No full text: Hoffa's fat pad (HFP) is part of the knee structure interposed between the joint capsule and the synovium. Recent studies have classified infrapatellar fat pad (IFP) disorders on a pathogenesis-based classification: traumatic disorders, post-traumatic disorders, lesions secondary to adjacent disorders. Masses or pseudo-masses may also be found within the IFP, however these alterations are much less frequent. Diagnostic imaging plays an important role in the diagnosis of masses and pseudo-masses of IFP and the first choice exam is a dynamic ultrasound study. We presented a rare case of Hoffa's fat pad herniation through the joint capsule, in a young child without history of knee injuries that has never been described before in the literature
