CellulitisDefinition Cellulitis is an acute inflammation of the connective tissue of the skin, caused by infection with staphylococcus, streptococcus or other bacteria (see also cellulitis - streptococcal). Causes, incidence, and risk factors 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 face and lower legs, although skin on other areas of the body may sometimes be involved. Risk factors for cellulitis include:
Symptoms
Signs and tests During a physical examination, the doctor may find localized swelling. Occasionally, swollen glands (lymph nodes) can be detected near the cellulitis. Tests that may be used:
Treatment 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 analgesics may be needed to control pain. Elevate the infected area, usually higher than the heart, to minimize swelling. Apply warm, moist compresses to the site to fight infection by increasing blood supply to the tissues. Rest until symptoms improve. Expectations (prognosis) 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). Complications
Calling your health care provider Call your health care provider if symptoms indicate that cellulitis may be present. 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. Prevention 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 chronic medical conditions. A body that is healthy can more easily fight bacteria before they multiply and cause infection, while a body that is run down has less protection against infection. Illustrations
