[Salami and extrinsic allergic alveolitis: a new occupational disease in Switzerland].

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.

Alveolitis, Extrinsic Allergic

[Decrease of intestinal absorption of 47-calcium in chronic alcoholism].

Intestinal 47-calcium absorption has been studied in 34 chronic alcoholics, 17 of whom were cirrhotics (group A) and 17 non-cirrhotics (group B). These patients were compared with 44 normal subjects (group C). In group C, the 47Ca 2 h plasma % of the dose showed a significant negative correlation to the total body weight (p less than 0.001) and a positive correlation with the serum albumin (p less than 0.05). The mean intestinal absorption of 47Ca expressed as 2 h plasma % of the dose multiplied by total body weight was 131 +/- SD 52 in group A and 136 +/- SD 71 in group B. These two means are significantly low (p less than 0.001 and p less than 0.002 respectively) in relation to that found in group C (168 +/- SD 32). These results suggest that intestinal calcium absorption is diminished in chronic alcoholism even in the absence of hepatic cirrhosis.

Alcoholism

[25-hydroxy vitamin D deficiency with reduction of intestinal calcium absorption and bone density in chronic alcoholism].

Plasma levels of 25-hydroxycalciferol (25-OH-D), 47-calcium intestinal absorption, bone mineral content and the biologic parameters of phospho-calcium metabolism were studied in 30 chronic alcoholics, 15 with Laennec's cirrhosis (group A) and 15 without (group B). These patients were compared with 27 normal subjects. In group A, the mean 25-OH-D plasma level was 23.7 +/- SD 18.5 microgram/l and in group B 35.2 +/- SD 21.8 microgram/l. These mean levels were lower than those of the control group, which were 57.2 +/- SD 22.5 microgram/l (p less than 0.001). The mean value of the 47Ca intestinal absorption, measured as the percentage of the ingested dose per litre of plasma and multiplied by the body weight, was also significantly lower in group A, which was 140 +/- SD 47 (p less than 0.01), and in group B, which was 145 +/- SD 69 (p less than 0.05), compared with the normal subjects whose average was 182 +/- SD 45.6. Similarly, the total plasma calcium was low: 1.99 +/- SD 0.24 mmol/l in all the alcoholics, while that of the control group was 2.22 +/- SD 0.18 mmol/l (p less than 0.001). For the 30 chronic alcoholics there was a positive correlation between 25-OH-D and 47Ca intestinal absorption, (r = 0.484; p less than 0.004). This suggests that in chronic alcoholism the deficiency of 25-OH-D induces a diminution of the intestinal absorption of calcium which, in the long term, can result in bone demineralization evidenced in the patients studied by a bone mineral content lower than normal (p less than 0.001).
