What Parkinson's Teaches Us About the Brain
October 11, 2011
Cellulitis is an acute inflammation of the connective tissue of the skin, caused by infection with staphylococcus, streptococcus or other bacteria (see also Erysipelas).
The skin normally has many types of bacteria living on it, but intact skin is an effective barrier that keeps these bacteria from entering and growing within the body. When there is a break in the skin, however, bacteria can enter the body and grow there, causing infection and inflammation. The skin tissues in the infected area become red, hot, irritated and painful.
Cellulitis is most common on the lower legs and the arms or hands, although other areas of the body may sometimes be involved. If it involves the face (erysipelas), medical attention is urgent. People with fungal infections of the feet, who have skin cracks in the webspaces between the toes, may have cellulitis that keeps coming back, because the cracks in the skin offer an opening for bacteria.
Risk factors for cellulitis include:
During a physical examination, the doctor may find localized swelling. Occasionally, swollen glands (lymph nodes) can be detected near the cellulitis. Your health care provider may mark the edges of the redness with a pen, to see if the redness extends beyond the marked border over the next several days.
Tests that may be used:
Cellulitis treatment may require hospitalization if it is severe enough to warrant intravenous antibiotics and close observation. At other times, treatment with oral antibiotics and close outpatient follow-up is enough. Treatment is focused on control of the infection and prevention of complications.
Antibiotics are given to control infection, and
Elevate the infected area, usually higher than the heart, to minimize swelling. Rest until symptoms improve.
Cure is possible with 7 to 10 days of treatment. Cellulitis may be more severe in people with chronic diseases and people who are susceptible to infection (immunosuppressed).
Call your health care provider if symptoms indicate that cellulitis may be present. Seek medical attention urgently if it appears to involve the face.
Call your health care provider if you are being treated for cellulitis and new symptoms develop, such as persistent fever, drowsiness, lethargy, blistering over the cellulitis, or extension of the red streaks.
Avoid skin damage by wearing appropriate protective equipment when participating in work or sports. Also, clean any breaks in the skin carefully and watch for redness, pain, drainage, or other signs of infection.
Finally, maintain good general health and control
