[Cross-over epidemiologic study of symptoms and respiratory function in workers at a furniture factory].

An epidemiological survey on symptoms and diseases (collected with CNR standardized questionnaire) and on lung function (forced vital capacity and derived indexes; CO diffusing capacity) has been carried on in workers of a furniture plant in Arezzo. Significantly higher prevalence rates of cough in smokers than in non smokers, and of cough, phlegm, wheeze in non smoker workers than in the control group from a general population sample were present. A not significant relationship of symptoms and working years was also found. Lung function indices were in the normal range; smokers had significantly lower values than non smokers. A lower FEV1%, after adjusting for age and smoking, was shown by subjects with more working years. Thus, in a modern furniture plant the risk of adverse health effect seems to be slight: this conclusion may be confirmed by the ongoing longitudinal survey.

[Validity of a specific bronchial provocation test with proteolytic enzymes in occupational bronchial asthma caused by enzymatic detergents].

Six asthmatic subjects exposed to enzymatic detergents derived from B. Licheniformis were examined by means of a specific Bronchial Provocative Test (sBPT) with solutions of the enzyme. All subjects, except for one, were positive to prick tests with solutions of the "crude" enzyme and with Alcalase, and showed high levels of specific IgE by RAST. The sBPT with solutions of the enzyme, administered by means of a Bird Mark 7 nebulyzer in IPPB with measurement of the delivered dose, showed a positive response in all 6 subjects. No positive result was obtained in 5 normal subjects and in 5 non exposed asthmatic patients, even at much higher doses of the delivered enzyme. The occupational-type sBPT showed only two positive results out of the 6 examined. A good relationship was observed between bronchial hyperresponsiveness and provocative dose of the enzyme. Therefore, the sBPT with solutions of the enzyme is proved to be highly sensitive and specific in confirming the diagnosis of occupational asthma due to proteolytic enzymes.
