[Visual disorders, functional defects and vitamin deficiencies].

The comparison between complaints, functional defects and vitamin deficiencies is reported for several professional groups characterized by different work conditions. Results suggest that complaints are an useful indicator of visual load and that retinal sensitivity to the light is especially tried. Longitudinal studies are required to verify whether some functional alterations on the aging process of the eye can be aggravated by a visual overload. Visual complaints, functional defects and vitamin deficiencies as indicators of visual load.

[Teaching of occupational medicine in Switzerland].

In this paper, the different training programs in the field of occupational health are described. It appears clearly that training programs differ widely from one university to another. A new step will be fulfilled with the development of a degree in occupational health for FMH specialists. It is mentioned that the lack of a valuable status for industrial physicians may adversely affect the evolution of training programs in Switzerland.

[Ocular fatigue induced due to work on visual screens].

It appears that visual complaints, as they are expressed by numerous TV screen operators, are associated with common eye defects. Our results based on a survey with questionnaires and visual testing sustain such an hypothesis. As a consequence, solving eye problems at TV screens requires both the improvement of visual displays and the visual adaptation of users. If impossible working-time should be reduced.

Fetal breathing and adaptation to maternal hemorrhage in the sheep.

The effect of maternal hemorrhage in chronic preparations was studied on fetal lambs in the last month of gestation. Fourteen to 20 per cent of maternal blood was estimated to have been removed within 30 minutes, which resulted in a drop of 30 per cent of mean maternal arterial pressure. A fetal bradycardia started 28 +/- 13 minutes after the beginning of maternal hemorrhage. It lasted 30 +/- 15 minutes and was concomitant with a rise in fetal arterial pressure. It was followed by a long-lasting fetal tachycardia of 130 +/- 38 minutes and was corrected only by reinfusion of blood to the mother. The fetal blood gases demonstrated a mild asphyxia with a persistent metabolic acidemia until reinfusion of blood to the mother. Maternal and fetal plasma cortisol levels rose significantly at the end of the hemorrhage. Tracheal fluid flow did not change. Fetal breathing recorded 20 hours before and 24 hours after the experiment did not show consistent changes, but during fetal bradycardia there was no fetal breathing. Recent clinical investigations in this field have been made in the human fetus to estimate standards of fetal well being. These peculiar animal experiments do not show any significant improvement by recording fetal breathing over the recording of prelabor fetal heart rate.

[Epidemiology of chronic bronchitis].

In this short paper, the definition of chronic bronchitis, as it is now widely accepted by epidemiologists, is given and a comparison is made with the disease as usually referred to by general practitioners. Risk factors which are related to the development of the disease are then briefly discussed and the importance of internal parameters is underlined. At last, the methodological difficulties which arise in the assessment of the relationship between air pollution and respiratory symptoms are emphasized.
