Trichloroethylene (TCE) is a toxic chemical commonly used as a degreasing agent, and it is usually found in a colorless or blue liquid form. TCE has a sweet, chloroform-like odor, and this volatile chlorinated organic chemical can cause toxic hepatitis, neurophysiological disorders, skin disorders, and hypersensitivity syndromes. However, the hypersensitivity pneumonitis (HP) attributed to TCE ...
Occupational asthma (OA) can be induced by fumes of manual metal-arc welding on stainless steel. In recent years, the use of special stainless steels (SSS) with high chromium content has increased. This study presents two cases of OA caused by manual metal-arc welding on SSS. In both cases, the diagnosis of OA was based on respiratory symptoms, occupational exposure and positive findings in the...
A 62-year-old previously healthy male who was a welder/smoker/drinker was admitted to Kani Tono Hospital for severe hypoxemia (Day 0). Initial physical and radiological examinations suggested an acute exacerbation of chronic obstructive pulmonary disease. However, respiratory failure developed rapidly, and he died on Day + 4. Aspergillus fumigatus was identified after his death, and he was diag...

The large problem to create manual welds of constant high quality results from missing optical information during the actual welding process. Due to the extreme brightness conditions e.g. in arc welding and the use of protective glasses even experienced welders can hardly recognize details of the welding pool, the welding seam and the environment. This paper describes a new research project for...
