Acute cellulitis

Acute cellulitis literally is an acute infection that spreads all over the subcutaneous tissue. Basically there are two main types of bacteriological. The acute pyogenic cellulitis and the anaerobic acute cellulitis are the two kinds of acute cellulitis. The acute pyogenic cellulitis is generally caused because of Group-A Streptococci and Staph. aureus. It appears as a markedly red, hot, infiltrated edematous skin lesion and the borders of it are usually ill defined.

Symptoms

Many other symptoms like that of lymphangitis and lymphadenitis that involves local draining lymph glands are also found in the acute pyogenic cellulitis. The anaerobic acute cellulitis is a rare and is generally caused due to a synergistic infection with both the aerobic and anaerobic bacteria. With the causal organisms that include aerobes and anaerobes, two clinical syndromes might develop, namely necrotizing fasciitis and progressive bacterial synergistic gangrene. The necrotizing fasciitis infection generally takes place on the lower extremities, abdominal wall, perineum and other operative wounds. The process spreads all along the facial plane leading to the extensive necrosis while the external appearance of the skin remains normal at the initial stage. That is why the damage or the infection is much more extensive than the extent of the overlying skin. The area that is involved is almost swollen, red, warm and painful. The infection always consist an element of Crepitus. The patient suffering from this infection is severely ill with symptoms of fever. Septic shock can also take place to such a patient.

Other symptoms

The other type of infection that is the progressive bacterial synergistic gangrene is a gangrenous ulceration of the skin that is caused due to a mixed bacteria flora. It generally follows abdominal or thoracic infection or trauma. A small, painful, superficial ulcer develops and steadily enlarges to form an ulcer with a rim of gangrenous skin. Acute bacterial cellulitis is a potentially severe infection that commonly recurs. The identification of preventable risk factors could lessen infection-related morbidity and cost and improve patient management. The aim of this study was to recognize the risk factors associated with lower-limb cellulitis, including both analyses of risk factors linked with cellulitis in either limb and risk factors in a single limb associated with cellulitis in the same limb.
