In the two decades following the First World War, American occupational medicine was consumed in cataloguing the pneumoconioses, and no physician was more prominent than Henry K. Pancoast of the University of Pennsylvania. In a landmark trial following the worst silicosis outbreak in the United States at Gauley Bridge, West Virginia, Pancoast testified for the defense, attributing the disease to tuberculosis. Pancoast was not an isolated commentator, as the prominence of the cases attracted some of the country's leading authorities on occupational medicine. Pancoast's error, as well as the accuracy of some of his colleagues, clarifies an important occupational disease in its epidemic period. There is also a less historically specific exposition of the impact of professional involvement in social policy, liability, and compensation.

The cholesterol storage disease of the lung is seldom and therefore we hardly think of it. An evident diagnosis can be given only by histological examinations. 2 cases are described where during life was diagnosed a silicosis and declared as an occupational disease. Autopsy revealed cholesterol storage disease without any signs of silicosis. These findings suggest, that in cases with low occupational quartz-dust-exposure it is advisable to extend the field of diagnostic procedures.

A survey of 762 New Jersey physicians showed that 35% reported seeing patients with either asbestosis, coal worker's pneumoconiosis, occupational asthma or silicosis. Three to four times as many patients with these diagnoses were seen as outpatients as were hospitalized. The implications of these results in using hospital discharge data for occupational disease surveillance are discussed.

For the stimulation of research on scleroderma and the prophylaxis of occupational scleroderma-like diseases and the prevention of iatrogenic injuries, respect., it is important to know the inducing environmental substances. Plastics (vinyl chloride, epoxy resins), solvents (chlorinated, aromatic and aliphatic hydrocarbons), drugs (bleomycin, pentazocine), cocaine (abuse) and contaminated rapeseed oil are more or less able to induce scleroderma-like diseases. Vinyl chloride disease is the best known among these. The toxic oil syndrome represents the most inglorious example of the recent time. Paraffin and silicon can act as adjuvants and induce a progressive systemic sclerosis. In our studies it could be shown, that silica is able to induce not only a silicosis, but also a true progressive systemic sclerosis after long term exposure. Acknowledgment of such cases as an occupational disease is justified and regulated by law in the German Democratic Republic.

Computerized hospital discharge diagnoses are useful for occupational disease surveillance. One thousand one hundred twenty-six individuals with asbestosis and 268 individuals with silicosis were identified in New Jersey for the four-year period 1979-1982. Computer-generated maps help to dramatize the localization of these conditions to certain geographic areas. The attributes and limitations of using hospital discharge diagnoses for occupational disease surveillance are discussed: initial follow-up data are presented for individuals with silicosis.

The whole contingent of patients, ill with silicosis manifested after interrupting work with dust, registered up to 1984, at the Clinic of Occupational Diseases, Sofia was examined. Analysis was made of the lasting disability of the patients. A study was performed on the relation between group of invalidity and age groups in the newly discovered cases; group of invalidity and length of service at dry drilling; group and diagnosis of the illness in stages; connection between x-ray morphological displays and functional disturbances and group of invalidity. Recommendations are given concerning the basic pneumoconiosis process and its complications and the interrelations between pneumoconiosis disease, chronic bronchitis and pulmonary emphysema.

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)

Clinical, roentgenological and lung-physiological findings in 5 patients with progressive scleroderma are reported. All of them showed an intensive exposure to crystalline silica of many years however without evidence of a silicosis. Criteria for legal recognition as an occupational disease are intensity and duration of quartz dust exposure. Legal recognition in the G.D.R. can be achieved in a special procedure called "Sonderentscheidverfahren".

"Vineyard sprayer's lung" is an occupational disease found in Portuguese vineyard workers. The radiographic picture resembles that of silicosis with micronodular disease in the early stages and progressive massive fibrosis in later stages, eventually resulting in endstage lung disease. The patients have a downhill course due to respiratory failure. The incidence of bronchogenic carcinoma is also higher than in the general population.

This essay focuses on the early history of industry and professional relationships around silicosis, the debilitating occupational lung disease, through a study of the role of the Industrial Health Foundation, an industry-sponsored group which has played a critical role in shaping the nation's agenda regarding industrial disease. From its start during the Depression, it has portrayed itself as an industry-sponsored agency that depended upon detached, disinterested professionals and experts to develop effective programs to address occupational disease. As an organization that brought together professional industrial hygienists, business groups, government officials, academics and researchers it serves as a means for understanding the intertwining of industrial and academic agendas. We explore some of the issues that arose regarding public policy and scientific investigations, asking: Under what conditions is it appropriate for professionals and scientists to work together with industrially sponsored organizations? What are the pressures that shape research questions, the range of possible solutions, and the control of scientific data? How can technically trained individuals avoid real or perceived conflicts of interest? At what point does the ostensibly disinterested goals of professionalism conflict with the self-interest of the sponsoring organizations?
