[The early diagnosis of cancer of the breast remains insufficient. A study of breast monitoring in women over 50 years of age in Lorraine-Champagne].

Although breast cancer in women over 50 years of age can be detected by physical examination and mammography, in our region many women of that age do not benefit from a satisfactory breast surveillance: 52.4% of women who had a general check-up between February and May 1989 have their breast examined by a physician once a year or more often; only 30% had a mammography less than three years ago; 34.2% examine themselves at least once a month.

Biochemical values of immigrant groups in north-east France.

Laboratory-test results for a population of immigrants living in north-east France revealed differences between the concentration of the blood constituents of immigrants and native French people. By immigrants we mean persons now living in France but coming from other geographical locations such as Italy, the Iberian Peninsula, northern or central Europe, northern Africa, or the Near or Middle East. Multiple regression analysis confirmed the need to establish reference limits in immigrants for many blood constituents because of a significant shift of the curve relative to that for the French population.

[Thoracic radiography in detecting heart diseases].

Within the scope of a physical examination, more than 147,000 patients from the Eastern part of France, were examined and had a chest X-ray, between 1982 and 1987. Seven physicians read those radiographs and reported their findings. After discussion of an interindividual variation noted between the seven physicians, the authors present the major findings of this study: relation between a cardiovascular anomaly discovered on the radiographs and a high blood pressure; relation between a cardiovascular anomaly discovered on the radiographs and one or several electrocardiographic anomalies; relation between anomaly of the cardiovascular silhouette as seen on the radiographs and increased levels of triglycerides and cholesterol in young adults.

[Description of electrocardiographic data in children and adolescents. Apropos of more than 100,000 ECGs].

The authors record the most frequent electrocardiographic anomalies in children and teenagers. The course of the frequency of ectopic rhythms and right focal blocks is studied. Variations in the duration and axis of the electrocardiographic complexes are described in terms of age and sex, and reference figures are presented.

[Biological constants in migrants].

Until now, clinical chemists, clinicians, physicians dealing with the problem of migrant biology dispose only reference limits established for an autochtone population. But can these really be applied? We compared 28 blood constituents of a migrant population with those of the french population. We defined five geographic areas: Italy, the Iberian Peninsula, Northern Africa, Northern and Central Europe and the Near and Middle East.
