Beef allergy in children
No full textBeef allergy was poorly known before the '90s. Since then, a number of papers appeared elucidating the nature, epidemiology, and symptoms of beef allergy in children allergic to cow's milk and children suffering from atopic dermatitis. It is now clear that beef allergy is not an infrequent occurrence, with an incidence between 3. 28% and 6.52% among children with atopic dermatitis, its incidence may be as much as 0.3% in the general population. A diagnosis of beef allergy must be supported by skin prick tests, RASTs, and challenges. The specificity and sensitivity according to type of test and the type of extract, however, remains to be evaluated. Despite the fact that other allergens can be sensitizing, the major beef allergen is bovine serum albumin (BSA). Beef-sensitive children are also sensitized to ovine serum albumin, as well as to other serum albumins; therefore, the use of alternative meats in beef-allergic children must be carefully evaluated on an individual basis. Because industrial heat processing is more efficient than domestic cooking in reducing reactivity in beef-sensitive children, freeze-drying and homogenization may support the introduction of processed beef into the diet of beef-allergic children

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
