[Angioplasty of the proximal left anterior descending artery outside the acute phase of myocardial infarction. Apropos of a series of 100 consecutive patients].

The indications of percutaneous transluminal coronary angioplasty (PTCA) of the proximal left anterior descending artery (LAD 1) must take into consideration the importance of the threatened myocardial territory in case of complications and the supposedly increased risk of restenosis of this arterial segment. One hundred consecutive patients (average age 59.9 +/- 11.4 years with 77% of men) outside the acute phase of myocardial infarction were included in this retrospective open study from January 1st 1988 to March 1st 1992. There were 76 cases of single vessel. The average left ventricular ejection fraction was 64.8 +/- 12%. During the hospital period, there were no deaths. 1 myocardial infarction despite emergency coronary bypass surgery, and 2 programmed coronary bypass procedures. During follow-up, "clinical restenosis" as defined by the authors was observed in 29.7% of cases; 1 patient died of cardiovascular causes, 18 had a repeat PTCA with a success rate of 100%. The clinical restenosis rate of repeat PTCA was 33%. One patient underwent a third PTCA with a successful outcome. Ten coronary bypass procedures were necessary. Restenosis was more common after PTCA of lesions situated on a bifurcation and when high inflation pressures had to be used. Restenosis was constant after repeat PTCA when the initial restenosis occurred before the 60th day.

[Silicosis in Switzerland. A half century of observation. The physician's viewpoint].

In Switzerland, the first cases of silicosis were recorded by Zangger in 1900. Since 1930, patients with silicosis have been provided with certain services by the "Caisse Nationale Suisse d'Assurances" (i.e. Swiss National Insurance Fund), an organization enforcing the Occupational Accidents and Diseases Bill. However, it took another two years before an effectively organized struggle against silicosis was started. Eventually, by 1938, this specific pneumoconiosis was acknowledged as an occupational disease under Swiss Law. Thus, the CNSA has been concerned with this disease for half a century, and it seems relevant now to take stock of the situation. From 1930 to late 1980, 9690 cases of silicosis were accepted by the CNSA. Nearly one half (46%) of these silicotic patients were still alive on December 31, 1980; another third had died of silicosis and the rest of other affections not related The origin of cases has remained remarkably constant over the course of time. Underground working and the stone-working industry account for the majority of cases (70%), followed by smelting works (16%) and the ceramic industry (5%). The remaining 9% are due to various causes. Silicosis hazards have declined but still remain real. In late 1980, 1287 companies in Switzerland were being monitored from this standpoint. More than two-thirds (67%) belong to the stone-working industry (even though only 30% of hazard-exposed workers are employed in this sector), 10% are involved in underground work (10% of hazard-exposed workers), 10% are smelting industries (36% exposed) and 6% belong to the ceramic industry (17% exposed). Since 1950, the number of hazard-exposed people has fluctuated between relatively narrow limits (i.e. 15,000 and 20,000). Corresponding figures for previous periods are not known. Some facts indicate that silicosis is becoming less problematic: a) The annual incidence rate of silicosis in Switzerland has evolved in three distinct phases. From 1930 to 1940 the number of new cases recorded each year rose regularly. From 1940 to the late 1960s, the incidence levelled off (200-300 cases yearly); then, from 1974, it dropped rather sharply and less than 100 new cases have been recorded yearly since 1978 (97 in 1978, 69 in 1979 and 68 in 1980). b) The average age at diagnosis of silicosis has regularly increased. Until 1940, the average age of recorded silicotic patients was about 40. The threshold of 50 years was reached between 1953 and 1957. More recently (between 1978 and 1980) the corresponding figure was 68.2.(ABSTRACT TRUNCATED AT 400 WORDS)

[Current occupational respiratory pathology in Switzerland].

The main features of occupational industrial respiratory diseases in Switzerland can be summarized as follows: -Silicosis: 9750 cases from 1930 to 1979. At present low annual incidence (less than 100 cases), age at first diagnosis over 40 years, at death almost 70 years. - Asbestosis: 130 cases from 1939 to 1979. 30 cases of mesothelioma (21 without asbestosis; 9 with), 9 of bronchial carcinoma and 1 of gastric cancer in the 130 cases of asbestosis. - Acute toxic lung (irritant gases such as chlorine, phosgene, nitrous gases), occupational asthma, extrinsic alveolitis and finally occupational chronic bronchitis are the principal diseases also observed.
