Endoscopic Excision of Symptomatic Os Trigonum in Professional Dancers
No full textAbstract: Introduction: This study presents clinical results of excision of a symptomatic os trigonum with endoscopic procedure in professional ballet dancers. The hypothesis was that posterior endoscopic excisions of the os trigonum would be safe and effective in treating PAIS related to the os trigonum.
Methods: Twelve professional dancers underwent excision of a symptomatic os trigonum for PAIS by posterior endoscopic technique, after failure of a conservative treatment. The patients were evaluated pre- and post- operatively according to the American Orthopedic Foot and Ankle Society (AOFAS) hindfoot score, the Tegner score and the Visual Analogic Scale (VAS). Surgical time, timing of return to sports (RTS), patient satisfaction and any complications related to the procedure were recorded.
Results: The average duration of post-operative follow-up was 38.9±20.6 months (range 12-72). The mean value of the Tegner scale increased from 4.3±0.8 pre-operatively (range 3-5) to 9±0.2 at follow-up (P<0.05). The mean value of the AOFAS score increased from 67.8±6.0 (range 58-76), to 96±5.1 at follow-up (range 87-100) with seven patients out of 12 (58.3%) reporting the maximum score of 100 points (P<0.05). RTS was 8.7±0.7 weeks (range 8-10). No major complications were recorded.
Conclusion: This study demonstrate that the endoscopic excision of symptomatic os trigonum with a 2-portal technique, after failure of a conservative treatment, is characterized by excellent results with low morbidit
Rate of complications due to neuromuscular scoliosis spine surgery in a 30-years consecutive series
Full text linkPURPOSE:
The aim of this study was to evaluate the rate of intraoperative and postoperative complications in a large series of patients affected by neuromuscular scoliosis.
METHODS:
It was a monocentric retrospective study. In this study have been considered complications those events that significantly affected the course of treatment, such as getting the hospital stay longer, or requiring a subsequent surgical procedure, or corrupting the final result of the treatment.
RESULTS:
Of the 358 patients affected by neuromuscular scoliosis treated from January 1985 to December 2010, 185 that met the inclusion criteria were included in the study. There were recorded 66 complications in 55/185 patients. Of that 66 complications, 54 complications occurred in 46/120 patients with Luque's instrumentation, while only 12 complications occurred in 9/65 patients with hybrid instrumentation and this difference was statistically significant (p < 0.05); 11/126 patients with pelvic fixation and 5/59 without pelvic fixation, as well as 45/156 patients treated by posterior approach alone and 10/29 patient that underwent combined anterior-posterior approach suffered complications but both this did not result in a statistical significant difference (p > 0.05).
CONCLUSIONS:
The surgical treatment in neuromuscular scoliosis is burdened by a large number of complications. An accurate knowledge of possible complications is mandatory to prepare strategies due to prevent adverse events. A difference in definitions could completely change results in good or bad as well as in our same series the adverse events amounted at almost 30% of cases, but complications that due to complete failure would amount at 9.19% of patients.

Arthroscopic Treatment of 2 Consecutive Cases of Dysplasia Epiphysealis Hemimelica of the Ankle: A 5-Year Follow-Up Report
Full text linkThe dysplasia epiphysealis hemimelica (DEH) is a rare disease of unknown etiology consisting in an abnormal osteocartilaginous growth at the epiphysis, usually hemimelic with histological findings similar to benign osteochondroma. In this case series, we described the results of the arthroscopic treatment of 2 consecutive cases of intra-articular ankle localization of DEH in 2 patients aged 9 and 10 years. The good result obtained, persistent at the 5-year follow-up, leads us to consider the arthroscopic approach as a reliable treatment in patient affected by intra-articular ankle DEH
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
Chest pain caused by multiple exostoses of the ribs: A case report and a review of literature
Full text linkAbstract
The aim of this paper is to report an exceptional case of
multiple internal exostoses of the ribs in a young patient
affected by multiple hereditary exostoses (MHE) coming
to our observation for chest pain as the only symptom
of an intra-thoracic localization. A 16 years old patient
with familiar history of MHE came to our observation
complaining a left-sided chest pain. This pain had increased
in the last months with no correlation to a
traumatic event. The computed tomography (CT) scan
revealed the presence of three exostoses located on the
left third, fourth and sixth ribs, all protruding into the
thoracic cavity, directly in contact with visceral pleura.
Moreover, the apex of the one located on the sixth rib
revealed to be only 12 mm away from pericardium. Patient
underwent video-assisted thoracoscopy with an additional
4-cm mini toracotomy approach. At the last 1-year followup,
patient was very satisfied and no signs of recurrence or
major complication had occured. In conclusion, chest pain
could be the only symptom of an intra-thoracic exostoses
localization, possibly leading to serious complications.
Thoracic localization in MHE must be suspected when
patients complain chest pain. A chest CT scan is indicated
to confirm exostoses and to clarify relationship with surrounding
structures. Video-assisted thoracoscopic surgery
can be considered a valuable option for exostoses removal,
alone or in addiction to a mini-thoracotomy approach, in
order to reduce thoracotomy morbidity
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
