Valutazione ecografica del tendine di Achille e dell'entesi rotulea nei giocatori di calcio e basket: potrebbe essere utile per prevedere lo sviluppo di lesioni muscolari e tendinee?
No full textBACKGROUND: Achilles and patellar entheseal abnormalities are frequently seen in athletes and healthy subjects at ultrasound (US) evaluation. However, to our knowledge, no studies have been performed to assess the possible asso-ciation between the presence of subclinical entheseal abnormalities and the possibility to develop muscular injuries in professional athletes. The aim of this study was: to compare US entheseal abnormalities in a group of athletes with age and sex-matched healthy controls and to assess the 12 months risk for the development of symptomatic muscular and tendon injuries at lower limb. METHODS: Consecutive soccer and basket players attending our clinic for routine controls were asked to participate. US evaluation of Achilles tendon and patellar tendon insertion at tibial tuberosity was performed in order to evalu-ate the presence of subclinical enthesopathy. The evaluation of tendons and entheseal thickness was also performed. Finally, athletes were followed up for 1 year and the development of muscular and tendon injuries at lower limb was evaluated. RESULTS: Forty athletes and 20 healthy controls were enrolled for this study. Overall, entheseal US abnormalities were found in 25 (62.5%) athletes. Both Achilles tendon and enthesis thickness were significantly higher in respect to healthy controls. During the follow up, 6 (15%) athletes suffered a muscle injury at lower limb and 1 (2.5%) an Achil-les tendon lesion. None of the enrolled controls reported any injuries. Logistic regression analysis did not find any statistically significant associations between the presence of entheseal abnormalities and the development of injury. However, a tendency to develop muscular injuries at lower limb was found in those athletes with Achilles tendon abnormalities (odds ratio [95% CI]: 6 [0.83-43], P=0.07). CONCLUSIONS: A tendency for an association of US Achilles tendon enthesopathy with muscular lower limb injuries was found. This may suggest that screening of asymptomatic individuals could be of use in identifying those who are at higher risk of developing injury, which may allow targeted modifications of training or other preventative regimens.

La spondilodiscite delle spondiloartriti sieronegative
No full textSpondylodiscitis has been found in seronegative spondyloarthropathies. Usually lesions are clinically silent even if patients, sometimes, complain a localized back pain of a few months duration. Diagnosis will depend on the absence of an infectious focus and on clinical, laboratory and radiological findings. Computerized tomography and nuclear magnetic resonance are sensitive and specific methods to detect discitis but their expensive cost is a limiting factor for their wider use. Therapy will be both farmacological and rehabilitative
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
Psoriatic arthritis: treatment strategies using anti-inflammatory drugs and classical DMARDs
Full text linkPsoriatic Arthritis (PsA) is a chronic inflammatory disease typically characterized by arthritis and psoriasis variably associated with other extra-articular manifestations. PsA has been considered a milder and less disabling disease compared with rheumatoid arthritis (RA), even if some studies showed that PsA had joint erosions and damage. In addition, about 20-40% of PsA patients have axial skeleton involvement that may lead to functional limitation and deformity. The treatment of PsA ranged from initial treatment with non-steroidal anti-inflammatory drugs (NSAIDs) to one or more disease-modifying anti-rheumatic agents (DMARDs) for the suppression of inflammation in patients with recalcitrant peripheral joint disease. In clinical practice, the most widely used DMARDs are methotrexate (level of evidence B), sulfasalazine (level of evidence A), leflunomide (level of evidence A), and ciclosporin (level of evidence B). However, the efficacy of these agents in inhibiting joint erosions has not been assessed in controlled studies. Finally, the effectiveness of DMARDs in treating enthesitis and dactylitis is controversial. The present paper revised the evidence-based results on treatment with “conventional” therapy for PsA. The revision was based on all the subsets of the diseases, namely the various manifestations of the articular involvement (peripheral, axial, enthesitis, dactylitis) as well as the skin and nail involvement
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
