M. Posgay et al., RADIOLOGICAL ASPECTS OF HARD METAL DISEASE, RoFo. Fortschritte auf dem Gebiete der Rontgenstrahlen und der neuenbildgebenden Verfahren, 159(5), 1993, pp. 439-443
The results of 30 years screening of exposed workers in the hard metal
industry are presented in a retrospective study. There were 11 worker
s who had radiographic signs of pulmonary fibrosis. No correlation was
found between intensity and/or duration of exposure and the stage and
progression of pulmonary fibrosis. In 45% of the cases there was prog
ression of the fibrosis after cessation of the exposure. Steroid thera
py in three cases relieved the subjective symptoms but there was no re
gression of the fibrosis.
