Overview

The authors demonstrated a long-term clinical study on the occurrence of calcifications in X-ray image of lungs in 2500 patients with diagnosis of silicosis pulmonum and coal-miners pneumoconiosis realized retrospectivelly from medical documents and examinations of patients at the department of occupational medicine the Faculty Hospital in Martin between 1953 and 1998. Opacity of calcification density in parenchyma and the hilar area of lungs (eggshell calcificates) occurred in 1.8% cases of reported professional pneumoconioses. The summary of findings presented in tables showed the different occurrence in subgroups of miners in ore mines, coal mines and in other professions where workers were exposed (since 1930 and consequently) to extreme and currently not present risks of massive dust inhalation with silicon oxide.

The paper presents 8 case studies describing a range of exposures and other data incl. different X-ray images and findings of lungs with cementicles. The authors paid a special attention to a rare case of lithopthysis in pneumoconiosis with a semiquantitative analysis using the energy dispersive spectrometry (EDS). The presence of cementicles in lungs did not change the value of a financial compensation in fibroconioses.

Key words:
a group of 2500 patients, X-ray evaluation of lung cementicles, subgroups of miners of ore and coal mines, mixed and other exposures, analysis of bronchiolites
