Rheumatoid arthritis (RA) is an inflammatory disorder of unknown origin that primarily involves the synovial membrane of the joints. Phagocytosis produces enzymes within the joint. The enzymes break down collagen, causing edema, proliferation of the synovial membrane, and ultimately pannus formation. Pannus destroys cartilage and erodes the bone. The consequence is loss of articular surfaces and joint motion. Muscle fibers undergo degenerative changes.

A cerebrovascular accident (CVA), an ischemic stroke or “brain attack,” is a sudden loss of brain function resulting from Cerebral Vascular Accident (Ischemic Stroke) a disruption of the blood supply to a part of the brain.

Definition Asthma is a chronic inflammatory disease of the airways characterized by hyper-responsiveness, mucosal edema, and mucus production. This inflammation ultimately leads to recurrent episodes of asthma symptoms: cough, chest tightness, wheezing, and dyspnea. Patients with asthma may experience symptom-free periods alternating with acute exacerbations that last from minutes to hours or days. Asthma, the most common chronic disease of childhood, can begin at any [...]

Benign prostatic hyperplasia (BPH) is enlargement, or hyper-trophy, of the prostate gland. The prostate gland enlarges, extending upward into the bladder and obstructing the out-flow of urine.
