In chemical pneumonia, inflammation of lung tissue is from poisons or toxins. Only a small percentage of pneumonias are caused by chemicals. Many substances can cause chemical pneumonia, including liquids, gases, and small particles, such as dust or fumes, also called particulate matter. Some chemicals only harm the lungs; however, some toxic materials affect other organs in addition to the lungs and can result in serious organ damage or death.
The shoulder joint can be replaced by an artificial shoulder or shoulder replacement for pain caused by arthritis or when the shoulder is severely fractured or broken. Arthritis is when the cartilage on the ends of the bones is gone and there is bone rubbing on bone in the joint.
Your shoulder replacement should last for at least 10 years. After this, the artificial parts of the joint may start to loosen from general wear and tear. A repeat shoulder replacement operation is also known as a revision.houlder replacement usually takes around two hours, depending on how complicated your surgery is. Once the anaesthesia has taken effect, your surgeon will make a cut, usually down the front of your shoulder. Your surgeon will remove some of the humeral head (the top of your upper arm bone).
