[An episode of extraoccupational lead poisoning].

An episode of non occupational lead intoxication observed in the four members of family is described. While three of them had only biochemical signs of abnormal lead absorption, the remaining subject presented the serious clinical features of plumbism. The source of intoxication was contaminated wine. The importance, for diagnostical and medico-preventive purposes, of a possible non occupational absorption of lead is stressed.

[The work environment in steel-cord production].

We present the most interesting results of an environmental survey carried out in a factory producing steel-cord. On the basis of our data it results that the most important risks are due to the exposition to noise, to microclimate (particularly during summer) and to some gaseous pollutants which are present only in some departments. We briefly analyse the main lines of technical prevention.

Problems of inference from hypothesis-generating studies on lung cancer and occupation based on routine hospital records.

This paper discusses inference from hypothesis-generating studies on occupational risks for lung cancer based on routine hospital records. A hospital-based case-control study on 567 male lung cancer patients and 906 controls provided a practical example. Among possible causes of bias, the effects of poor detail in the occupational information, of a large proportion of exclusions due to incomplete information, of cardiovascular diseases as the prevalent diagnosis among controls, of selecting cases and controls from different hospitals with likely differences in referring areas, and the problem of multiple comparisons are highlighted. Significant excess lung cancer risks were found for farmers, miners, crushers, stonemasons and cement plant workers, and stock handlers and stevedores. Positive findings with small numbers of observations are more likely to be artificially generated, but also the precision of more robust risk estimates may be affected. The limits to inference from hypothesis generating case-control studies based upon routine hospital records, such as in the example described, outweigh the advantage of the ready availability of these data-bases.
