Validity of questionnaire criteria in mass screening for the diagnosis of peptic ulcer.

Epidemiological studies of peptic ulceration in the stomach and duodenum based on a standard questionnaire were carried out among the employees of a sulphur mine. The results obtained in the preliminary cross-sectional study were checked against a sample of 180 people who had undergone radiological examination of the alimentary tract. The validity of the questionnaire was then assessed by comparison of these two sets of results. The study shows that a more revealing screening test may be based on a wide range of questions rather than on a smaller set of specific questions.

Sickness absence caused by chest diseases in relation to smoking and chronic bronchitis symptoms.

The relationship between sickness absence caused by chest diseases, smoking habit, and symptoms of chronic bronchitis among the workers of a fertilizer factory in Karaków is examined. The analysis of absence was based on the spells and days of absence registered during a period of six years. The results show that the group of workers with symptoms of chronic bronchitis had many more spells and days of absence caused by chest diseases than persons free from these symptoms. The activity and chronicity of bronchitis symptoms strongly influenced the level of absence, but the role of smoking was not so evident. From the results obtained it appears that analysis of absence can be a valid screening test in the detection of chronic chest diseases, the frequency of which can easily be estimated from absence data.
