Siderosis, also called welder's lung, is a lung disease caused by breathing in iron or iron oxide dust. Siderosis is considered to be an occupational illness because people breathe in the iron dust at work. The condition usually shows up on X-rays as small, opaque spots on the worker's lungs.
Warfarin is an anticoagulant medicine (blood thinner). Warfarin-induced skin necrosis refers to a rare condition in which there is paradoxical blood clotting. Blood clots block the blood vessels and cause necrosis, i.e., an area of skin is destroyed. Warfarin induced skin necrosis affects one in every 10,000 patients prescribed warfarin. The onset is usually within the first 2 to 5 days of warfarin therapy, when the blood tends to clot more than is normal.
