Type IV allergy in the food processing industry: sensitization profiles in bakers, cooks and butchers
No full textData about the impact of allergic contact dermatitis in food processing occupations are scarce. The objective of this study was to identify the most frequent allergens and sensitization profiles in employees of the food processing industry. The results of patch testing performed in 873 bakers, cooks and butchers suspected of having occupational allergic contact dermatitis from 33 dermatological departments of the Information Network of Departments of Dermatology (IVDK) from 1992 to 1999 were analysed. A final diagnosis of allergic contact dermatitis was made in 213 patients (24.4%). Qualitative and quantitative differences in allergen profiles could be identified. Significantly higher sensitization rates were found in employees in the food processing industry, compared to the total test population, for nickel sulphate (22.4% versus 17.2%, p < 0.0005), thiuram mix (4.9% versus 2.6%, p < 0.0005), formaldehyde (3.5% versus 2.1%, p < 0.005) and Compositae mix (6.2%, p < 0.0005). Significantly lower sensitization rates were found for thimerosal (4.5% versus 6.9%, p < 0.05). For patch testing in food workers, we recommend the standard, the rubber and the Compositae series, as well as patients' own products according to the individual history
Allergic contact dermatitis in patients with anogenital complaints
No full textOBJECTIVE: Allergic contact dermatitis is a common anogenital disease. STUDY DESIGN: The results of patch testing performed on 1,008 patients evaluated for allergic anogenital contact dermatitis from 21 dermatologic departments in the Information Network of Departments of Dermatology (IVDK) from 1992 to 1997 were analyzed. RESULTS: A final diagnosis of allergic contact dermatitis was made in 351 patients (34.8%). Irritant contact dermatitis was diagnosed in 230 patients (22.8%) and other, nonspecified forms of perianal eczema in 228 patients (22.6%). The remaining cases were due to other distinct dermatologic diseases. Analyzing patch test data from this large group of patients showed that the allergen spectrum resembled that of all patients (54,000) tested from 1992 to 1997. However, dibucaine HCl ranked fourth among contact allergens in the study population. Positive reactions to (chloro-)-methyl-isothiazolinone and to benzocaine were observed more frequently among patients with anogenital complaints as compared to the total IVDK population (3.7% vs. 2.5% and 2.7% vs. 1.5%, respectively). In general, active agents of topical medications and popular remedies, preservatives and ointment bases appeared to cause allergic reactions most frequently. CONCLUSION: Patients with chronic anogenital diseases seem to have a high risk of becoming sensitized. For patch testing we recommend the standard series, dibucaine HCl, propolis, bufexamac and other ingredients from topical preparations according to the patient's history

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

No full textVariations 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
