asbestosis/nicotine

A statistically significant association between cigarette smoking and radiologic readings of irregular opacities was observed in a case-control study of 430 South African asbestos miners (OR = 3.03; 95% confidence interval, 1.50; 6.11). In another case-control study of 487 dead South African

During the three years 1979-81, all patients with bronchial carcinoma of World Health Organisation types I to IV were given a questionnaire to determine occupation, smoking habits, and exposure to asbestos. Chest x rays were screened for the presence of pleural plaques. Of the men, 96.2% were

Environmental carcinogen exposure is requisite for the development of nearly all lung cancer, and it is well known that asbestos exposure interacts synergistically with tobacco smoke to induce lung cancer. However, the precise molecular lesions induced by asbestos are unknown. Furthermore, it is

BACKGROUND Whether occupational exposure to asbestos causes airway obstruction remains controversial. OBJECTIVE This study evaluated lung function in relation to cumulative exposure to asbestos in a large cohort of retired or unemployed workers exposed to asbestos. METHODS The study population

OBJECTIVE Laryngeal diseases caused by exposure to asbestos are listed in the current German list of occupational diseases under number 4104. Parallel to a multicenter study to evaluate whether a CT scan should be included in the examinations for occupational diseases according to the German

CYP1A1 and CYP1B1 are involved in the metabolism of carcinogens. The effect of CYP1A1 and CYP1B1 polymorphisms as genetic modifiers of risk was investigated in individuals with asbestos, silica dust or ionizing radiation-induced occupational tumours compared to exposed non-cancer subjects suffering

The occupational group composed of the iron-miners working at the bottom of the mines in Lorraine makes up a high risk population for lung cancer (The carcinogenic index is 5 to 12 times as high as that of the population of non-miners). The authors report a new series of 270 cases in support of this

The aim of this study was to evaluate cases of asbestos-related diseases in workers exposed to asbestos in the province of Palermo (Italy) from 2005 to 2009. Data were collected from medical records and from reports from the Prevention and Safety in the Workplace Unit of the provincial health

Asbestos causes four diseases in humans: Lung fibrosis (asbestosis) follows heavy exposure and, in industrialized countries, is mainly a relic of past working conditions. The risk of pleural fibrosis and plaques is likely to be linearly dependent from time since first exposure and is present for all

OBJECTIVE To examine the effects of asbestos exposure and tobacco smoking on the level and rate of change of the diffusing capacity of the lung for carbon monoxide (DLCO). METHODS A cohort study of 934 people (including both mine workers and town residents) exposed to crocidolite (blue asbestos) at

BACKGROUND Asbestos is banned in most Western countries but related malignancies are still of clinical concern because of their long latencies. This review identifies and addresses some controversial occupational and clinical aspects of asbestos-related malignancies. METHODS Papers published in

Cytochrome P450 2E1 (CYP2E1), a phase I enzyme, is involved in the activation of a broad spectrum of pro-carcinogens. The importance of this enzyme for pharmacology is derived from its unique substrate spectrum. Large inter-individual differences in the toxicity of its substrates are known. We

BACKGROUND The adverse health effects of occupational exposure to asbestos dust may occur several years after first exposure. The objective of the study was to assess the relationship between lesions in the respiratory system and the factors contributing to occupational exposure to asbestos
