- Abstract:
- Tailor's chalk has caused nasal hyperreagibility in the majority of students and teachers of a fashion school upon their presence in the school rooms. The problems usually started shortly after entering the rooms and subsided without residues soon after leaving the building. The association with a special chalk was generally suspected or even taken as proven; no problems existed in connection with ''normal'' chalk. Most of those patients struck by the problem perceived the symptoms as troublesome. However, since they became manifest only in the school rooms and were there accepted as unavoidable, none of those affected had yet consulted a physician. After notification of the formula of the special chalk we could ascribe the problems to benzoic acid, since only this chemical had been added for special purposes to the normal chalk. Benzoic acid can cause urticaria upon direct contact with normal or diseased skin or generalized urticaria after intake of foods that contain benzoic acid as a preservative. Now we have to add an additional symptom to the list of problems that can be caused by benzoic acid, i.e. probably a non-immunologic mediated problem of the nasal mucosa, but also of the lower respiratory tract. This reaction seems to occur frequently and might, in combination with the other non-immunologic immediate-type reactions, surpass the cases of delayed-type hypersensitivity reactions caused by benzoic acid.
