Atopic dermatitis – Perspectives and unmet medical needs
No full textAtopic dermatitis (AD) is a chronic inflammatory skin disease for which many new insights have been gained in recent years through a better understanding of pathophysiology, concomitant diseases and therapeutics in particular. In this review, new and practice‐relevant results from current research are presented. Many studies have been performed on the diagnosis of AD and on different subtypes, yet no diagnostic biomarker or clinical predictor of treatment response has been established. For topical treatment, some agents such as Janus kinase (JAK) inhibitors are in advanced stages of clinical trials or already approved in some countries, which will be available in Europe for the treatment of certain eczema subtypes in the foreseeable future. Current systemic therapies in Europe include two antibodies for inhibition of the interleukin (IL)‐4/13 signaling cascades and three oral JAK inhibitors with somewhat different efficacy and safety profiles. Among the antibody therapies for AD already advanced in development, promising new targets include blockade of IL‐31, of neurokinin‐1 receptor on sensory neurons, and inhibition of the OX40/OX40L axis for cutaneous dendritic cell and T lymphocyte interaction. Primary prevention and modulation of sequential disease progression as well as effects on concomitant diseases by early therapeutic intervention will be important questions in future research on AD
data analysis 2009–2018
Full text linkBACKGROUND
Allergic contact dermatitis caused by shoes is common and new relevant allergens have been identified.
OBJECTIVES
To investigate the pattern of type IV sensitization in patients with suspected allergic contact dermatitis of the feet related to shoes as a presumed culprit trigger.
METHODS
Retrospective analysis of data of the Information Network of Departments of Dermatology (IVDK), 2009-2018.
RESULTS
Six hundred twenty-five patients with presumed shoe dermatitis were identified in a cohort of 119 417 patients. Compared to patients with suspected contact sensitization from other allergen sources (n = 118 792), study group patients were more frequently sensitized to potassium dichromate (10.8% vs 3.5%), colophony (7.2% vs 3.7%), mercaptobenzothiazole (MBT; 4.0% vs 0.6%), mercapto mix (4.6% vs 0.6%), and p-tert-butylphenol formaldehyde resin (1.6% vs 0.5%). Sensitizations to urea formaldehyde resin, melamine formaldehyde resin, glutaraldehyde, tricresyl phosphate, and phenyl glycidylether were rare. Moreover, reactions to compounds in the leather or textile dyes test series were scarce.
CONCLUSION
A distinct sensitization pattern was observed in patients with suspected allergy to shoe materials. Although substances with low sensitization rates should be removed from the leather and shoe patch test series, novel potential allergens should be added

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
