BACKGROUND Retroperitoneal fibrosis (RPF) is an uncommon disease with unknown causation in most cases. The pathognomonic finding is a fibrous mass covering the abdominal aorta and the ureters. Our aim was to clarify the possible role of asbestos exposure in the development of RPF. The hypothesis was based on the ability of asbestos to cause fibrosis in(More)
BACKGROUND Cobalt production workers are exposed to metallic cobalt and nickel and their compounds and to different irritant gases. The aim of our study was to determine whether long-term exposure is associated with an increased occurrence of respiratory symptoms and findings or diseases, other than asthma, which is a known hazard, among cobalt processing(More)
The aim of this study was to determine whether occupational exposure to chromite, trivalent chromium (Cr(3+)) or hexavalent chromium (Cr(6+)) causes respiratory diseases, an excess of respiratory symptoms, a decrease in pulmonary function or signs of pneumoconiosis among workers in stainless steel production. Altogether, 203 exposed workers and 81 referents(More)
The objective of the present study is to determine the feasibility of chest computed tomography (CT) in screening for lung cancer among asbestos-exposed workers. In total, 633 workers were included in the present study and were examined with chest radiography and high-resolution CT (HRCT). A total of 180 current and ex-smokers (cessation within the previous(More)
BACKGROUND Inhaled asbestos fibres can cause inflammation and fibrosis in the lungs called asbestosis. However, there are no non-invasive means to assess and follow the severity of the inflammation. Exhaled nitric oxide (NO) measured at multiple exhalation flow rates can be used to assess the alveolar NO concentration and bronchial NO flux, which reflect(More)
Obstructive lung disease in two patients with Behcet's syndrome is presented. In both cases increased airways resistance, impaired PEF and FEV1.0 were found. In addition, diffusion capacity was slightly decreased in spite of enlarged total lung capacity and increased residual volumes. Both patients had mild hypoxaemia despite slight hyperventilation; a(More)
AIMS To investigate whether exposure to cobalt in cobalt plants has any measurable effect on the cardiovascular system. METHODS Occupational, cross sectional study, using a self administered questionnaire, blood pressure measurement, electrocardiography, and laboratory tests in which 203 male workers with at least one year of exposure to cobalt and 94(More)
Cohorts of Finnish asbestos sprayers and of asbestosis and silicosis patients were followed for cancer with the aid of the Finnish Cancer Registry in the period 1967-1994. Compared with the cancer incidence of the total Finnish population, asbestos sprayers had an increased risk for total cancer (standardized incidence ratio [SIR] 6.7, 95% confidence(More)
OBJECTIVE Many drugs are vestibulotoxic and may impair balance. Styrene is both ototoxic and neurotoxic, but its effect on balance has been little studied. We evaluate the effect of low concentrations of styrene on balance among Finnish fiberglass-reinforced plastic boat manufacturers. METHODS From 252 male employees, we measured postural stability and(More)
