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.
Surgery may be a good first choice for shoulder weakness caused by complete tears, especially when the rotator cuff is otherwise healthy (little or no degeneration). Surgery may be considered if you have severe pain and loss of shoulder function that has not responded to appropriate nonsurgical treatment.
