No full textWe report the case of a 66-year-old caucasian woman affected by Kartagener's syndrome (KS), a genetically transmitted disorder characterised by situs viscerum inversus, bronchiectasis and sinusitis, who also developed rheumatoid arthritis (RA). The impaired mucociliary function typical of KS caused recurrent paranasal sinus and lung infections, as shown by CT scans of the sinuses and chest. The coexistence of KS and RA in our patient was probably accidental. Given the small number of patients in whom an association of the two disorders has been described, it is impossible to establish whether KS might play a role in the pathogenesis of RA

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
Patient preferences in the choice of anti-TNF therapies in rheumatoid arthritis. Results from a questionnaire survey (RIVIERA study).
No full textObjective. To identify the determinants of anti-TNF-naive patients’ preferences for the route of
administration of anti-TNF agents.
Methods. The study was carried out in 50 Italian rheumatology centres (802 patients). All patients
completed a 31-item questionnaire addressing their perceptions of current treatment and the preferences
for treatment with anti-TNF agents. Statistical methods included analysis of variance (ANOVA), t-test and
chi-square test.
Results. The response rate to the questionnaire was 97.6%. At the time of the survey, 310 (39.9%)
patients were dissatisfied with current treatments, owing to inefficacy, side effects and inconvenience
of administration. The i.v. and s.c. routes of administration were preferred by 50.2 and 49.8%, respectively.
No significant difference was found in patients by gender, age, RA duration or number of drugs
used. Reasons for the choice of i.v. administration were the safety of treatment at the hospital and the
reassuring effect of physician presence. The s.c. administration was chosen for the convenience of
treatment and in particular for home treatment. Patients dissatisfied with current therapy due to side
effects preferred s.c. administration (P1⁄40.029), whereas patients choosing the i.v. route had slightly
higher scores on ‘today pain’ (P1⁄40.047) and ‘articular pain’ (P1⁄40.023) of the Rheumatoid Arthritis
Disease Activity Index (RADAI).
Conclusions. Both i.v. and s.c. treatments were well accepted by patients. However, treatment choice
has to be discussed with patients, as individual preference seems to be determined by personal attitudes
towards safety and convenience, by past experience and by the perception of current disease status
