Necrotizing fasciitis. Otherwise known as flesh-eating bacteria. Diagnosis Flesh-eating disease can often be diagnosed based on the way the skin looks, along with pain in the area and a fever. This diagnosis can be confirmed by a variety of tests, such as an X ray or a computed tomography (CT) scan. A CT scan is a procedure by which X rays are directed at a patient's body from various angles and the set of photographs thus obtained assembled by a computer program. This procedure is sometimes called a computerized axial tomography (CAT) scan. Samples of tissue under the skin can also be taken. Analysis of these samples will tell if the flesh-eating bacteria are present. Signs and symptoms of flesh-eating disease include: • acute localized pain in the infected area; • swollen, red, and hot skin; • blistering; • grating or crackling sensation felt when touched; • fever; • fast heart beat; • change in level of consciousness; and • low blood pressure. It starts with pain and reddening at the sight, followed by turning black. It might itch a bit and bleedings, pus and drainage may occur at the site of the infection. If left untreated, death can occur in less than a week. It can only occur if an open wound if left untreated and it gets infected. Treatment. Immediately taken to the hospital and treated with intravenous antibiotics. A surgeon must be consulted immediately if it is suspected or diagnosed. The type of surgeon depends on the area. Patients with this disease require admission to the intensive care. Organ failure is common. You could die in less than a week. Sometimes oxygen treatment, combined by pressure is given, but it requires a special chamber which most hospitals don't have. A person can contract the disease by having an unhygienic open wound. Over 70% of cases are recorded in patients with one of the following clinical situations: immunosuppression, diabetes, alcoholism/drug abuse/smoking, malignancies, and chronic systemic diseases. It occasionally occurs in people with an apparently normal general condition. The infection begins locally at a site of trauma, which may be severe (such as the result of surgery), minor, or even nonapparent. Patients usually complain of intense pain that may seem excessive given the external appearance of the skin. With progression of the disease, often within hours, tissue becomes swollen. Diarrhea and vomiting are also common symptoms. In the early stages, signs of inflammation may not be apparent if the bacteria are deep within the tissue. If they are not deep, signs of inflammation, such as redness and swollen or hot skin, develop very quickly. Skin color may progress to violet, and blisters may form, with subsequent necrosis (death) of the subcutaneous tissues. The patient will appear to be feverish and very ill, and if not treated immediately, it will lead to a certain death.
