Controlled study of oxatomide vs disodium chromoglycate for treating adverse reactions to food
No full textA controlled, cross-over trial was carried out to compare the efficacy and safety of oxatomide vs disodium chromoglycate (DSCG) for treating food allergy and intolerance. Twenty patients (15F, 5M; mean age 36.6 years), with chronic urticaria (twelve patients) or eczema (eight patients) caused by food allergy (ten cases) or food intolerance (ten cases), were treated with oxatomide (60 mg/day in a single evening administration) and with DSCG (2000 mg/day) for six weeks. The two treatments were separated by a 3-week wash-out period. All the patients completed the trial. During the treatment, both drugs succeeded in controlling the symptoms. With oxatomide, the wheals totally disappeared from 75% of the patients (p = 0.00135), the eczematous lesions disappeared from 64% (p = 0.056), and the itching from 70% (p = 0.00012); the figures for DSCG were 33%, 50% (p = 0.038) and 50%, respectively. Both drugs were well tolerated and there was no need to discontinue the treatment of any of the patients
[The assessment of the incidence of food allergy or intolerance in patients with respiratory allergy]
No full textIn this study we have evaluated the possible relationship between food allergens and hypersensitivity to grass pollens. One hundred-thirty patients with grass pollen pollinosis and symptoms probably related to adverse reaction to foods were selected. Skin prick test for food allergens was positive in 79 patients (60.7%) Statistical analysis using chi-square test showed a high significant relationship between grass pollen and nuts, peanuts, beans and peas (p less than 0.0001). Elimination diet and challenge test allowed us to identify the responsible foods in 61 out 79 patients (77.2%). Twelve patients were affected by food allergy (challenge test, skin prick test and RAST positive and concordant); 49 patients suffered from intolerance. Possible causes of this high relationship are discussed
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
[Treatment of Behcet's syndrome with colchicine]
No full textThe aim of the present study was to investigate the usefulness of colchicine in the treatment of Behcet's syndrome. Ten patients suffering from Behcet's syndrome were selected for this purpose. The patients were treated with 1 mg/day of colchicine associated with 1 mg of betametasone during the initial florid phase of the disease. After the acute phase, betametasone was withdrawn. The patients were observed for a period ranging from 5 to 23 months. Biochemical and immunological parameters were measured at time 0 and every month in order to monitor the disease and the possible side effects of colchicine. All patients had a satisfactory control of the disease without showing any toxic effect
Variations on the Author
Get PDF“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
[Eczema and food allergy in the adult]
No full textWe have evaluated the relationship between eczema and food by using elimination diet and subsequently open and double blind challenge test in 15 patients. The clinical manifestations of 14 subjects were improved by elimination diet. Challenge test was positive in 10 patients. Nuts, tomatoes, milk, eggs and cereals were most frequently involved. Six patients suffered from food allergy (F.A.), 4 patients from food intolerance (F.I.) and 4 patients from suspected F.I. With the use of dietary elimination procedure the symptoms completely disappeared. The results obtained for the treatment of eczema with this procedure may be very encouraging
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
[Comparison of RAST with an immunoenzyme method in simultaneous determination of IgE specific for numerous air allergens]
No full textRecently, a new immunoenzymatic test (Allergy Screen Profile, ASP) has been proposed for the simultaneous determination of IgE specific for five inhaled allergens (Dermatophagoides, animal dander, trees, grass pollen and Parietaria). For evaluation of this test we compared the results obtained in twenty-seven patients suffering from respiratory allergy with RAST with those obtained using the new test. In 84.3% of cases there was positive concordance between the two tests. The specificity of ASP ranged from 71.4% to 100% and the sensitivity from 76.9% to 95.2% for the different allergens examined. A good correlation between ASP and RAST was particularly evident for Dermatophagoides, animal dander and trees. Therefore, ASP appears to be a suitable test for the simultaneous determination of IgE specific for different allergens
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
