Title Cutaneous reactions due to pyridinecarboxaldehyde, thiophenecarboxaldehyde - Isomerism
Original title Réactions cutanées aux pyridinecarbaldéhydes et thiophènecarbaldéhydes - Notion d'isomérie [in French]
Bibliographic information 1994, Vol.55, No.6, p.467-469. Illus. 16 ref.
Abstract A 27-year-old woman who underwent skin exposure to pyridinecarboxaldehyde and thiophenecarboxaldehyde at the workplace. In patch tests, 3-pyridinecarboxaldehyde produced urticaria whereas 2-pyridinecarboxaldehyde isomer induced eczema and no reaction was observed with 4-pyridinecarboxaldehyde. Patch tests made with thiophenecarboxaldehyde showed that the patient was sensitive to 3-thiophenecarboxaldehyde, which induced irritant erythema whereas there was no reaction with its isomer 2-thiophenecarboxaldehyde. Thus, depending on the position of the carbonyl carbon on the pyridine (ortho, meta or para) or thiophene ring, different reactions can occur.
