Head and neck dermatitis, a subtype of atopic dermatitis induced by Malassezia spp: Clinical aspects and treatment outcomes in adolescent and adult patients
No full textBackground and objectives: Head and neck dermatitis (HND) is a clinical variant of
atopic dermatitis (AD), presenting in adolescence or adulthood and characterized by
involvement of the head, neck, and superior part of the trunk. The role of Malassezia
spp has been advocated in the pathogenesis of HND, and antifungal agents represent
the treatment of choice.
Methods: A retrospective single-center study was performed to define the clinical
features and treatment response of HND among adolescent and adult patients.
Results: Thirty-one patients were identified, 17 with "adolescent-onset" and 14 with
"adult-onset" HND. Adolescent-onset HND positively correlated with a past history
of AD and presented with exclusive head and neck involvement (P < .05). Adult-onset
HND was associated with concomitant widespread atopic eczema, involving the flexural
areas of the upper and lower limbs, trunk, nipples, or hands (P < .05). A positive
response to itraconazole in combination with topical treatments was observed
in both groups.
Conclusions: This study delineates two HND clinical phenotypes: adolescent vs adult
onset. Different characteristics were observed in terms of relationship to AD and
eczema localization. A history of AD in childhood and presentation with exclusive
involvement of head and neck regions was observed predominantly in the adolescent-
onset form, while adult-onset HND often occurred in association with diffuse
dermatitis and a past history of AD was less frequent than in the adolescent group.
The study is limited by the single-center retrospective nature, which may lead to
diagnostic and selection biases, and the small cohort of patients.Background and objectives: Head and neck dermatitis (HND) is a clinical variant of atopic dermatitis (AD), presenting in adolescence or adulthood and characterized by involvement of the head, neck, and superior part of the trunk.

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
