[Minimal lipid anomalies in a group of men with early coronary disease compared to a control group]. / Anomalies lipidiques minimes dans un groupe d'hommes coronariens précoces comparé à un groupe témoin.

A group of 27 men with early coronary disease (mean age: 52 years) with cholesterol levels below 6.45 mmol/l and triglycerides levels below 2.3 mmol/l, who underwent a coronary angiography, is compared with a control group of 18 men (CG) with normal angiography. The only significant differences between the two groups are: a triglycerides levels slightly higher in the CM group (1.55 + 0.4 mmol/l) vs 1.18 +/- 0.37 mmol/l, p 0.001), a HDL-cholesterol level slightly lower in the CM group (1.08 +/- 0.19 mmol/l vs 1.26 +/- 0.21 mmol/l, p 0.01) and an Apo AI/Apo B ratio slightly lower in the CM group (1.02 +/- 0.24 vs 1.18 +/- 0.17, p 0.005). In the CM group, 21 patients in 27 present a lipid abnormality requiring, according to the European consensus recommendations, the prescription of hygieno-dietetic measures. In the CM group, 10 patients in 18 present a minimal lipid abnormality, also requiring hygieno-dietetic measures. These results are compared with the recommendations of the European consensus.

Chronic obstructive lung disease in gold miners.

A survey has been made of 2209 gold miners in the Republic of South Africa. The result showed that there is a significant dose-response relationship between dust inhaled and both chronic bronchitis and airways obstruction. This is found in smokers, ex-smokers and non-smokers. The effect of smoking is more potent than that of dust but there does not appear to be a dose-response relationship in regard to smoking. The effect of smoking differs from the effect of dust in that ex-smokers show less bronchitis and less airways obstruction than smokers, but ex-miners do not show a similar advantage over working miners.
