The results of 30 years screening of exposed workers in the hard metal industry are presented in a retrospective study. There were 11 workers 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 progression of the fibrosis after cessation of the exposure. Steroid therapy in three cases relieved the subjective symptoms but there was no regression of the fibrosis.

Giant cell interstitial pneumonia: case series with comprehensive ultrastructural analyses of "not only" hard metal pneumoconiosis.

Article Synopsis
- - Giant cell interstitial pneumonia (GIP) is a serious lung disease related to exposure to hard metals like tungsten, typically found in industrial tools, but it can also occur without clear exposure history.
- - In a study of five patients with GIP, researchers used advanced techniques to identify metal dust and asbestos in lung samples, finding trace amounts of tungsten and asbestos fibers associated with severe lung damage.
- - The results suggest that other factors beyond hard metal exposure might contribute to GIP's development, hinting at a complex immune mechanism that could explain its recurrence in lung transplants.
Optimizing the Structure of a Pt Metal-Chelating Polymer to Reduce Nonspecific Binding for Mass Cytometry.

Mass cytometry is a bioanalytic tool based on atomic mass spectrometry for detecting biomarker expression on individual cells. Current reagents employ metal-chelating polymers binding isotopes of hard metal ions. Polymers bearing chelators for soft metal ions offer the promise for a large increase in multiplexing capabilities, but examples reported so far often have unacceptably high levels of nonspecific binding (NSB).

Background: The fit of a metal-ceramic restoration is essential to its long-term durability. Regarding marginal and internal fit, there is not enough information about the technologies used in the production of metal-ceramic restorations. The aim of this in vitro study is to compare, both before and after porcelain firing, the marginal, axial, axio-occlusal, and occlusal fit of metal-ceramic restorations manufactured using casting, additive or subtractive computer-aided design, and computer-aided manufacturing techniques (CAD/CAM).

A variety of workplace exposures (organic or inorganic dusts as well as gases, fumes, or vapors) can cause diffuse interstitial lung disease. The latency period until onset of the disease can exceed 30 years. The disease course varies greatly and depends on the quantity of the inhaled substance and its fibrogenic effect.

Introduction: Lameness originating from the distal limb is common in sport horses and can vary depending on the dynamics of movement and the surface, with differences in shoeing exacerbating this variability. Driving horses work primarily on hard surfaces (pavement), whereas dressage horses work primarily on soft surfaces (riding arenas with sand). Driving horses are traditionally shod with small fixed studs made of hard metal, which are attached to the horseshoe at 4 points, while dressage horses are shod with a simple horseshoe.
