Summary
Fifty individuals with healed hand eczema were tested with nine primary irritants. The results were compared with those of carefully matched controls. An increased skin reactivity to primary irritants was not demonstrated in the ‘eczematous subjects’. The value of testing with irritants in pre‐employment evaluation could not be confirmed.
In 24 girls with atopic dermatitis and a history of irritation to wool, more intense itching was provoked on normal skin on the abdomen by a material with coarse wool fibres (36 microns) than with thinner fibres (20 microns). The probability of the materials causing itching could be predicted by the girls by handling the materials.
Many workers exposed to glass fibers experience an intense pruritus (itching), sometimes accompanied by erythema, erosions, and dermatitis. Patch tests to glass fibers provoked a papulovesicular dermatitis in about 25% of normal persons. Workers in the glass wool industry, whether or not clinically symptomatic, had the same levels of patch-test reactivity. A battery of skin tests failed to identify persons with an increased susceptibility to glass fiber pruritus. Some workers' skin becomes hardened by continuous exposure. This hardening is lost after a one-month holiday but is quickly regained. Barrier creams had no protective value in preventing glass fiber dermatitis.
During the last decades in most Western countries music education on all levels has undergone significant changes. In response to changes in the musical field in society at large, various popular music styles, previously almost totally neglected in institutional forms of music teaching based on Western art music, have been given increasing significance in the curricula of music education. This development has not, however, taken place without controversies. In most popular music genres the theoretical framework, learning principles and aims of musical practices differ in significant respects from those of the regulated activities of traditional institutions of music education, and the successful integration of popular genres into such institutions requires that these differences be acknowledged and resolved rather than ignored.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
