Observation of chronic constrictive pericarditis associated with pulmonary asbestosis is reported here. Heart catheterization revealed typical patterns of cardiac constriction. The diagnosis of asbestosis was based on pathologic features associated with a long history of asbestos dust exposure without evidence for tuberculosis. The etiology of this constrictive pericarditis was related to an as...

BACKGROUND Asbestosis and silicosis are debilitating pulmonary conditions resulting from inhalation of asbestos fibers or silica dust. PURPOSE We provide a descriptive analysis of asbestosis and silicosis hospitalizations in North Carolina to assess trends over a 10-year period. METHODS Events were defined as inpatient hospital discharges during the period 2002-2011 with an International Cl...

In the period 1966-82 lungs from 333 workers who had been employed at a Royal Naval dockyard were referred to the MRC Pneumoconiosis Unit where they were investigated for the severity of asbestosis, the presence of tumours, and an assessment of mineral fibre content and the type and amount of mineral present. The occupational exposure to mineral dust has been coded for 189 of these cases. There...

Markers of collagen metabolism may possibly be used in the assessment of pulmonary involvement in asbestosis-related pulmonary diseases. In this study the levels of the carboxyterminal propeptide of type I procollagen (PICP) and the aminoterminal propeptide of type III procollagen (PIIINP) were evaluated in bronchoalveolar lavage fluid (BALF), epithelial lining fluid (ELF) and serum from patien...

The diagnosis of pulmonary asbestosis is most often established based on clinical criteria and has both clinical and legal implications. Unfortunately, one of the confounding features in the diagnosis may be a history of cigarette abuse, which can produce interstitial opacities on chest imaging as well as diffusion defects on pulmonary function testing, criteria that are used in the diagnosis o...

By the radiological examination, differential diagnosis of asbestosis from chronic interstitial pneumonia such as IPF/UIP is difficult. The pathological features of asbestosis show the peribronchiolar fibrosis which suggest that asbestos fibers cause the inflammation of bronchioli. Therefore, the criteria for pathological diagnosis of asbestosis in 2010, contain the finding of peribronchiolar f...

The lungs from 36 past workers at an east London asbestos factory who had died from asbestos related disease were compared with lung tissue from 56 matched control patients being operated on in east London for carcinoma of the lung, correlating the severity of asbestosis and the presence of pulmonary carcinoma or mesothelioma of the pleura or peritoneum with an asbestos exposure index and type ...

Catalase (CAT) is part of the enzymatic defense system against reactive oxygen species (ROS), known to be involved in the pathogenesis of asbestosis. This study investigates whether CAT -262 C>T genetic polymorphism influences the risk of asbestosis in workers occupationally exposed to asbestos.The nested case-control study included 262 cases with asbestosis and 265 controls with no asbestos-re...

A new method for quantitative evaluation for high resolution computed tomography (HRCT) of the lungs was developed by assessment of the distribution of radiological densities within the lung slices. To enable effective reduction of data and improve the sensitivity of detection of abnormalities, the density distributions were analysed by curve fitting through the gamma variate model. The output ...
