[Occupational asthma caused by inhalation of cuttlefish bone dust]

This report describes a new case of occupational asthma in a goldsmith. A 25-year-old female suffered attacks of urticaria and asthma at each exposure to the dust of cuttle-fish bone used to polish gold jewellery. A specific occupational bronchial provocation challenge showed a dual asthmatic response with a maximum fall in FEV1 of 26% of the baseline value after 6 hours. A prick-test with crude cuttle-fish bone dust in glycerin 10% also gave a positive response.
