The suffix "-itis" indicates inflammation but not necessarily infection.Appendicitis,bacterial pneumonia,otitis media,and tonsillitis are most commonly caused by bacterial infection,so infection and inflammation are both present at the same time.Dermatitis is usually an allergic response without infection.Myocardial infarction is an injury caused by tissue anoxia and ischemia (lack of oxygen).Osteoarthritis is an inflammatory response to chronic wear and tear injury to a joint.Sprained ankle is a soft tissue injury that often results in a huge inflammatory response but infection is not present when the skin is intact.
