Severe Open Dislocation of the Hip with Exposed Femoral Head. A Case Report
Get PDFCase:
A 54-year-old woman was brought to our emergency department with an inferomedial open hip dislocation without fracture secondary to a railway trauma. We performed hip reduction, wound debridement, and stabilization with external fixation. After 7 months, hip arthroplasty was performed for severe hip instability and avascular necrosis of the femoral head.
Conclusion:
Open hip dislocation is an uncommon injury that is caused by high-energy trauma. It may be associated with serious management problems and complications, including infection and avascular necrosis of the femoral head
Conservative management of isolated medial subtalar joint dislocations in volleyball players: a report of three cases and literature review
No full textIsolated Subtalar Dislocations (SDs) are rare injuries, representing only 1% of all foot traumas. In the current literature, only a few reports have described this acute injury as a consequence of low-middle-energy trauma during sports activities and none in professional or recreational volleyball players. Further, to the best of our knowledge, no validated standard rehabilitation programs have been described for SDs as most of them are usually treated like an ankle sprain. This report describes 3 cases of isolated, closed medial SD, which occurred during non- professional volleyball activities. All cases were successfully treated by the same conservative method: standard radiographs for diagnosis, closed reduction, subsequent CT scan to exclude associated lesions, 4-week immobilization in a below-knee cast and an early physiokinesis therapy program. Further, a review of the recent literature concerning SD was performed. The standard method applied allowed our patients to return to full sports activity at 3 months from trauma, reaching a medium AOFAS score of 96.6 at minimum follow-up of 48 months. The treated cases and the review of the literature suggest that a conservative method and early mobilization should be the first-choice treatment for closed SD, even in volleyball players. Despite the absence of a sport-specific rehabilitation program for these injuries, early physiokinesis therapy, after no more than 4-week immobilization period, allowed the improvement of our patients' hindfoot stability and their fast return to full sports activities, without any recurrence at minimum follow-up of 2 years
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

Abstract: Muscle fatigue is a complex phenomenon that is influenced by the type of activity per-
formed and often manifests as a decline in motor performance (mechanical failure). The purpose of
our study was to investigate the compensatory strategies used to mitigate mechanical failure. A
cohort of 21 swimmers underwent a front-crawl swimming task, which required the consistent
maintenance of a constant speed for the maximum duration. The evaluation included three phases:
non-fatigue, pre-mechanical failure, and mechanical failure. We quantified key kinematic metrics,
including velocity, distance travelled, stroke frequency, stroke length, and stroke index. In addition,
electromyographic (EMG) metrics, including the Root-Mean-Square amplitude and Mean Fre-
quency of the EMG power spectrum, were obtained for 12 muscles to examine the electrical mani-
festations of muscle fatigue. Between the first and second phases, the athletes covered a distance of
919.38 ± 147.29 m at an average speed of 1.57 ± 0.08 m/s with an average muscle fatigue level of 12%.
Almost all evaluated muscles showed a significant increase (p < 0.001) in their EMG activity, except
for the latissimus dorsi, which showed a 17% reduction (ES 0.906, p < 0.001) during the push phase
of the stroke cycle. Kinematic parameters showed a 6% decrease in stroke length (ES 0.948, p < 0.001),
which was counteracted by a 7% increase in stroke frequency (ES −0.931, p < 0.001). Notably, the
stroke index also decreased by 6% (ES 0.965, p < 0.001). In the third phase, characterised by the loss
of the ability to maintain the predetermined rhythm, both EMG and kinematic parameters showed
reductions compared to the previous two phases. Swimmers employed common compensatory
strategies for coping with fatigue; however, the ability to maintain a predetermined motor output
proved to be limited at certain levels of fatigue and loss of swimming efficiency (Protocol ID:

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
