Osteochondritis dissecans of the scaphoid (Preincer's syndrome): 2 cases reports
No full textPreiser's syndrome is a rare osteochondrosis affecting the carpal scaphoid, frequently related with an avascular necrosis. Osteoarthritic changes of the articular cartilage, local synovitis, and loose fragments are the most common findings associated with this syndrome. We report here two patients with Preiser's syndrome, one with and one without a traumatic history, both presenting with pain, swelling and functional impairment of the wrist. In one patient radiography was sufficient for the diagnosis, in the other NMR was necessary to clearly establish type and extension of the lesion. Differential diagnosis may be sometimes difficult and the therapeutic approach depends on several aspects, including etiology and type of occupational activity
Evaluation of spinal mobility by pocket goniometer (Inclimed R) in patients with ankylosing: preliminary report.
No full textBackground: Ankylosing spondylitis (AS) is a chronic inflammatory disease affecting sacroiliac joints and whole the spine. The clinical instrument of functional evaluation of spine in AS is mainly based on BASMI score.
Objectives: The aim of our study was to verify the usefulness of new gravity-dependent and compass-needle pocket goniometer (IncliMed R, University of Padua) for AS spinal mobility measurement.
Methods: Forty one consecutive out-patients with AS (New York modified criteria) entered the study; 33 males and 8 females, age 46.5±12.3 years (range 21-73). Their active range of motion (AROM) of whole spine were evaluated by the same metrologist (B.L.) throughout the IncliMed R. The results of angular measures in 3 plane (frontal, coronal and sagittal) of cervical, thoracic and lumbo-sacral spine were expressed in grades and then summarized. At the same visit the classical BASMI evaluation was performed and VAS (last week), BASDAI and BASFI were applied.
The simple linear regression were performed for BASDAI, BASFI and VAS in the function of AROM and BASMI. The results were expressed as a coefficient of determination (r2) and the level of significance of p<0.05. The data were elaborated by SPSS 12.0.
Results: The AROM was 395±136.4° and BASMI was 3.9±2.3. The Pearson correlation between these tests were r=-0.78 (p<0.000). BASDAI, BASFI and VAS were respectively 41.3±26.2 mm, 30.5±23.7 mm and 27.1±23.2 mm. BASDAI, BASFI and VAS were more correlated with AROM, (respectively r2=0.30, p<0.000; r2=0.39, p<0.000; r2=0.14, p<0.05) than with BASMI (respectively r2=0.09, p=ns; r2=0.24, p<0.01; r2=0.06, p=ns).
Conclusion: AROM was significantly correlated with BASMI. The self-assessed questionnaires were better correlated with AROM than with BASMI. Probably BASMI as a simplify score reflects incompletely the disease activity and functional impairment of AS. We propose that the AROM by IncliMed R may be utilised as an objective method for the evaluation of AS, useful for the research and for clinical trials
Serum human cartilage glycoprotein 39 as a marker of arthritis associated with inflammatory bowel disease
No full textBACKGROUND: Common blood markers of arthritis are difficult to interpret in
arthritis associated with inflammatory bowel disease (IBD) owing to the
coexistence of two inflammatory events. No specific serological disease marker is
available for IBD.
OBJECTIVE: To determine a value of serum human cartilage glycoprotein 39 (HC
gp39) as a marker of arthritis associated with IBD.
METHODS: Serum levels of HC gp39 and ultrasensitive C reactive protein (CRP) were
determined in 121 patients with IBD: 58 without arthritis (IBD-nonA) and 63 with
arthritis (IBD-A), and in 20 healthy controls. IBD was classified as active
(aIBD) and non-active (naIBD), and patients with IBD-A were classified as type I,
II, and III arthritis by clinical activity indices.
RESULTS: HC gp39 was higher in IBD-A than in IBD-nonA (p<0.001) and controls
(p<0.01), while no difference was found between IBD-nonA and controls. CRP was
increased in both IBD-A and IBD-nonA compared with the controls (p<0.01 and
<0.05, respectively) and in aIBD-nonA v naIBD-nonA (p<0.05), but no difference in
CRP was found between aIBD-A and naIBD-A. Finally, a correlation was found
between the number of affected joints (NAJ) and HC gp39 (r = 0.6, p<0.001).
DISCUSSION: Increased serum levels of HC gp39, which were higher in IBD-A than in
IBD-nonA, suggest that this substance might be a marker of arthropathy in IBD. HC
gp39, because of its relationship with NAJ in IBD-A, may also be proposed as a
disease activity marker in arthritis associated with IBD

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
