[Salami and extrinsic allergic alveolitis: a new occupational disease in Switzerland]. / Salami et alvéolite allergique extrinsèque: une nouvelle pathologie professionnelle en Suisse.

The authors report a case of extrinsic allergic alveolitis in a patient working in an industrial butchery where she is involved in the preparation of dry sausages. The molds proliferating at the surface of these sausages, molds from the Penicillium family, are responsible for the disease. The respective value of laboratory tests such as the presence of precipitating antibodies and the analysis of the cellularity of the bronchoalveolar lavage are discussed. Whenever a patient presents with clinical symptoms suggestive of extrinsic allergic alveolitis a detailed search for any type of exposure linked to the professional milieu is required, so as to propose adequate modifications in work conditions or work place.

[Use of precipitins in the diagnosis of bird fancier's lung: apropos of 2 cases]. / Utilité des précipitines dans le diagnostic de la maladie des oiseleurs: à propos de deux cas.

Bird breeder's disease is a frequent diagnosis among the forms of extrinsic allergic alveolitis seen in the urban environment. We report two illustrative cases and discuss the respective roles of broncho-alveolar lavage cells and precipitating antibodies against avian antigens in the diagnostic work-up and the pathogenesis of the disease. In 1988 we evaluated over 100 sera from all over Switzerland with clinical suspicion of bird breeder's disease. In this cohort preliminary results show sensitivity of 85% and specificity of 92% for the presence of precipitins against avian antigens in the diagnosis of bird breeder's disease. The results suggest that this non-invasive test deserves revaluation as a diagnostic tool in bird breeder's disease.

[Humidifier disease. Role of endotoxins and precipitating antibodies]. / Maladie des humidificateurs. Rôle des endotoxines et des anticorps précipitants.

A case of an acute form of humidifier disease secondary to the inhalation of endotoxins (humidifier fever) is reported. The respective roles of endotoxins and precipitating antibodies in the diagnosis of the two forms of humidifier disease are discussed. This appears to be an important epidemiological problem in Switzerland, since the authors see approximately one case a month. With respect to treatment, preventive measures are necessary and usually sufficient.
