Coal workers' pneumoconiosis is a preventable occupational disorder of the respiratory system resulting from exposure to and retention of respirable coal dust. It exists in two distinguishable forms: simple, which is seldom if ever disabling, and complicated, also known as progressive massive
BACKGROUND
Bronchopulmonary disease due to inhalation of smoke from open woodfires represents a major health problem in developing countries. Due to increasing migration such patients also present to medical services in Europe.
METHODS
An 84-year-old Afghan housewife who never smoked nor has a
We present a case of a 76 year-old, non-smoking Honduran female who was referred to our clinic for years of persistent dry cough. Cardiac evaluation was unremarkable. She denied symptoms of heartburn, allergic rhinitis, and there was no personal or family history of asthma. Her physical exam
BACKGROUND
Anthracosis is the black pigment discoloration of bronchi with an unknown cause which can cause bronchial destruction and deformity (anthracofibrosis). The objective of this study was to determine the frequency of tuberculosis in anthracosis and evaluate their association.
METHODS
One
The predominant shapes of small opacities on the chest radiographs of 895 British coalminers have been studied. The aims were to determine whether irregular (as distinct from rounded) small opacities can be identified reproducibly, whether their occurrence is related to dust exposure, and whether
A critical review of the medical data accumulated on 100 consecutive miners referred for evaluation for disability under the Federal Coal Mine Health and Safety Act documented the generation of an excess of unreliable data at an unacceptable cost, even though the evaluations had been performed by
Bronchial anthracosis is the black discoloration of bronchial mucosa that exhibits similar manifestations to Chronic Obstructive Pulmonary Disease ( COPD). The etiology of this obstructive lung disease has not been elucidated and standard therapy for this disease has not been A 56-year-old man had worked as a furniture painter and had been exposed to tonoko polishing powder for 30 years. He had complained of dyspnea on exertion for 7 years, and was admitted to our hospital in 1991. A chest X-ray film revealed large opacities and emphysematous changes in both lung fields.
Arterial blood gas analysis is one of the criteria used by the Department of Labor to award total and permanent disability for coal workers' pneumoconiosis (Black Lung). We have observed that Black Lung claimants often undergo several blood gas analyses with widely differing results that sometimes
Underground U.S. coal miners were studied cross-sectionally for the association of respirable coal mine dust exposure with pulmonary function and symptoms of airways obstruction. The study group included 1,185 miners participating in Round 4 of the National Study of Coal Workers' Pneumoconiosis who
We reported a case of complicated silicosis that occurred in a glass manufacturing plant worker who had presumably been exposed to low-concentration free silica for almost 20 years. To the best of our knowledge this report is the first in the Republic of Korea. The physician's first impression was
We report an illustrative case of advanced "hut lung," or domestically acquired particulate lung disease (DAPLD), in a recently emigrated nonsmoking Bangladeshi woman with a history of 171 hour-years of exposure to biomass smoke. She presented with symptoms of chronic cough, dyspnea, and early
BACKGROUND
Although severe impairment of pulmonary function is believed to occur commonly in complicated pneumoconiosis, the relationships of simple coal workers' pneumoconiosis (CWP) to pulmonary function and respiratory symptoms have remained under debate. The study aims to investigate if simple
BACKGROUND
The objective of this study was to discuss the spirometric characteristics of anthracofibrosis which is a from of bronchial anthracosis associated with deformity.
METHODS
Forty anthracofibrosis subjects who were diagnosed with bronchoscopy were enrolled in this prospective study. Static
Indoor air pollution appears to be a major environmental and public health hazard for large numbers of the underdeveloped world's population. A detailed environmental history is important for making diagnosis in most individuals from foreign rural settings with nonspecific respiratory symptoms. In
