The purpose of this study was to examine the effects of walking exercise through a 6-min walking test on subjective dyspnea, pulmonary function test, arterial blood gas analysis, and activities of daily living to provide base data for the nursing intervention of pneumoconiosis patients. The subjects were pneumoconiosis patients men aged over 60. This quasi-experimental study was designed with a...

24 Years of Pneumoconiosis Mortality Surveillance in Australia: Derek R. SMITH, et al. International Center for Research Promotion and Informatics, National Institute of Occupational Safety and Health—Asbestosis, silicosis and Coal Worker’s Pneumoconiosis (CWP) represent three of the most important occupationally-related dust diseases in Australia. To gain a clear picture of pneumoconiosis tren...

29 physicians (A1-Group) and 24 physicians (A2-Group) attending the 1st and 2nd "Asian Intensive Reader of Pneumoconiosis" (AIR Pneumo) training course, respectively, and 22 physicians (B-Group) attending the Brazilian training course took the examination of reading the 60-film set. The objective of the study was firstly to investigate the factor structure of physicians' proficiency of reading ...

OBJECTIVE To develop and consolidate a comprehensive database on the occurrence of pneumoconioses in an industrialized region of Brazil, with a special focus on the activities most frequently related to these diseases. METHODS A retrospective, observational study was conducted in order to gather data on cases of pneumoconioses treated at the outpatient clinic of the State University at Campin...

The underground workers in the Dutch coal-mines have been radiographed (70 mm.) seven times since 1949. The prevalence of coal-miners' pneumoconiosis shows a continuous decrease in all age groups. To evaluate the effect of the intensive system of dust suppression over this period a cohort analysis was made of the proportion ofmen with pneumoconiosis with the same number of years of exposure und...

An unexpected finding in a survey of a random sample of men from the Rhondda Fach valley in South Wales suggested an association between blood group A and coal-workers' pneumoconiosis. A further and larger sample of 1,250 miners and ex-miners from the same area, covering the same age range of 35 to 64 years, was chosen at random from the population in order to verify this finding. Each man was ...

A cross sectional radiological survey of workers exposed to pottery dust during the manufacture of wall tiles and bathroom fittings was conducted in a South African factory. Roughly one third of workers with 15 or more years of service in high dust sections of the factory had pneumoconiosis. Previously undiagnosed advanced cases, including two with progressive massive fibrosis, were working in ...

OBJECTIVE To evaluate by computed tomographic scanning the paranasal mucosal changes of coal workers with and without pneumoconiosis. METHODS Examination of images and scores from paranasal computed tomographic scans. The study participants were 26 coal workers with pneumoconiosis, 29 coal workers without pneumoconiosis, and 20 controls. All were men. The extent and patterns of inflammatory p...

OBJECTIVES To explore whether the inhalation of coal mine dust increases the risk of premature death in miners, a survival analysis was conducted in a cohort of 2738 patients with simple pneumoconiosis in the Huai-Bei coal mine, in China. METHODS Age specific mortalities were calculated by disease severity in terms of pneumoconiotic category with the life table method. The progressions from s...

A more detailed analysis of material from the 20-year follow-up of men in the Rhondda Fach confirms the similarity between the Standardised Mortality Ratios (SMRs) of miners and exminers with radiological categories 0, 1, 2, 3 and A (120.3, 116.5, 119.0, 115.7, and 120.1 respectively) as well as the difference between these SMRs and that of the non-moners (98.7). The specific death rates show a...
