Granulomatous slack skin. Report of a case and review of the literature.
No full textWe describe a patient with granulomatous slack skin (GSS) who has been followed for 15 years and present clinical, histological, immunohistochemical, ultrastructural, cytogenetic, and molecular findings. The clinical and pathological aspects of the 20 cases of GSS reported in the recent literature are reviewed and compared with those of the present cas

No full textGranulomatous slack skin (GSS) is a rare disorder which is considered a slowly evolving T-cell lymphoma associated with granulomatous inflammation that mediates clastolysis. A combined cytogenetic, molecular, and cellular analysis was conducted on a clinically and histologically defined case of GSS. Cell cultures obtained from the skin biopsy showed trisomy of chromosome 8, and the DNA sample extracted from the skin biopsy showed a T-cell receptor beta-chain rearrangement
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
Subungual exostosis. Histological and clinical considerations on 30 cases
No full textThe authors review 30 cases of subungual exostosis, 27 in the foot and 3 in the hand. In approximately 80% of the cases, errors in initial diagnosis had been made, and the affection had been confused with ordinary verrucae, mycoses or pyogenic disease. Histological examination showed that in some cases the neoformation ossified by an enchondral mechanism similar to that of osteocartilaginous exostosis, while more often the mechanism was of the intramembranous or mixed type. The treatment consisted of resection of the exostosis at its base after removing the nail. Complete healing occurred in all cases
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
