A Stonemason's Pneumoconiosis Due to Pyroxene-andesite

Pneumoconiosis due to graphite dust.

Lassar Dunner (1945a) recorded the clinical and radiological findings in five men who had been exposed to " pure graphite " dust. They had been exposed for 17, 18, 20, 20, and 34 years respectively, and no other dusts were known to have been implicated. Three of the men had cough, sputum, and dyspnoea; the other two had no complaints. Radiographs showed reticulation with nodulation, and the que...

Pneumoconiosis due to Fuller's earth.

Mixed pneumoconiosis due to silicates and hard metals associated with primary Sjögren's syndrome due to silica

Here, we describe the case of a 75-year-old man who presented with a 3-year history of progressive dyspnea on exertion (classified as grade II/III on the modified Medical Research Council scale) and persistent dry cough. He had worked as a professional welder for 35 years, welding alloys, polishing weldments by sandblasting and steel blasting, and regularly performing isolation of fixed applian...

Computed tomography features of liparitosis: a pneumoconiosis due to amorphous silica.

The purpose of this study was to describe the radiological features of pleural, parenchymal and mediastinal damage due to occupational inhalation of pumice. In total, 31 workers were evaluated for annual follow-up. Spiral computed tomography (CT) was obtained in the three patients with evident parenchymal abnormalities at chest radiograph. High-resolution computed tomography (HRCT) was performe...

Pulsatory andesite lava flow at Bagana Volcano

[1] Using a time series of TerraSAR-X spaceborne radar images we have measured the pulsatory motion of an andesite lava flow over a 14-month period at Bagana Volcano, Papua New Guinea. Between October 2010 and December 2011, lava flowed continuously down the western flank of the volcano forming a 3 km-long blocky lava flow with a channel, levees, overflows and branches. We captured four success...
