A recent increase in reports of necrotizing fasciitis resulting from group B streptococcus has alerted physicians to a possible concomitant increase of toxic shock-like syndrome. We report the second case of group B streptococcus causing necrotizing fasciitis and toxic shock-like syndrome. A black woman, aged 52 years, with newly diagnosed diabetes mellitus had necrotizing fasciitis type II of the left groin. Hypotension, elevated bilirubin and liver enzymes, and adult respiratory distress syndrome rapidly developed. Because group B streptococcus was isolated from a normally sterile site, the patient's condition met the criteria for toxic shock-like syndrome. Extensive surgical debridement, hyperbaric oxygen therapy, and intravenous antibiotic therapy (including clindamycin) were required for complete recovery. The antitoxin effects of hyperbaric oxygen therapy and clindamycin should be further investigated for the treatment of such patients.

We reviewed eight patients with necrotizing fasciitis of odontogenic origin. There were three women and five men, mean age 58 (range 46-72), and none had any associated medical condition such as diabetes. All cases had symptoms of toothache for a mean duration of 34 days (range 26-42) before they sought treatment. Infection originated in the molar teeth region, and initially presented as an odontogenic or periodontal abscess. The clinical features of necrotizing fasciitis became apparent only after the superficial fascia had been invaded. The transient unusually reddish hue for a dark skin might be explained by the fact the deep fascia and muscles were affected before the superficial fascia and skin. Necrosis of the skin began in the submandibular region and progressed downwards. The necrotic area was less than the extent of infection. Antimicrobial treatment, debridement, and fasciotomy improved healing. Delay before appropriate treatment had an adverse affect on outcome, and one patient died.

Necrotizing cellulitis and fasciitis may be difficult to recognize. When skin necrosis is not obvious, the diagnosis must be suspected if there are signs of severe sepsis (accelerated heart or respiratory rates, oliguria, mental confusion.) and/or some of the following local symptoms or signs: severe spontaneous pain, indurated edema, bullae, cyanosis, skin pallor, absence of lymphangitis, skin hypoesthesia, crepitation, muscle weakness, foul smell of exudates. Many risk factors are suspected. A recent case-control study demonstrated that using ibuprofen increased the risk of cellulitis complicating chickenpox in children. Evidence is lower for other risk factors that are present with a high prevalence in most series: local lesion of skin or mucous membranes (acute or chronic disease, traumatism, surgery.), diabetes, arteriopathy, alcoholism, obesity, immunosuppression, NSAIDs. The risk of streptococcal necrotizing fasciitis is increased when in contact with patients infected by the same streptococcus.

Cellulitis and necrotizing fasciitis can be distinguished by the depth of the cutaneous lesion and classically by the different bacteria implicated. This classification is not taken into account by the practitioner because of a similar therapeutic strategy. That is why most authors used a single title: necrotizing soft tissue infection. The potential severity of these infections required a quick diagnosis to decrease the risk of mortality and severe functional consequences. The analysis of the literature doesn't allow to establish the incidence of these infections. It was demonstrated that infections due to Streptococcus serogroup A increased over the last few years, thanks to a specific surveillance system. Risk factors leading to these infections are: cutaneous trauma, age, diabetes, varicella in children, contact with people infected by Streptococcus. The most recent studies demonstrated a frequent polymicrobism of the infections, with anaerobes, Streptococcus, Staphylococcus, and gram-negative rods. At the onset of the disease, the diagnosis is difficult to establish. Pain, induration of tissues, a rapid evolution, the inefficacy of antibiotic treatment suggest the diagnosis of necrotizing infection. MRI, when available, is a good technique to reveal the depth of the infection and necrosis. Surgery will confirm the diagnosis and allow for debridement of necrotized tissues. A delayed surgery increases the mortality risk factor, as stated in numerous studies.

The course of severe invasive group A beta-hemolytic streptococcal (GABHS) infections is often precipitous, requiring prompt diagnosis and rapid initiation of appropriate therapy. Therefore, physicians must have a high index of suspicion of this disease, particularly in patients at increased risk (e.g., those with varicella or diabetes mellitus). Although a relationship between the use of nonsteroidal antiinflammatory drugs and severe invasive GABHS infections has been suggested, at present data on which to base a clinical decision about the use or restriction of nonsteroidal antiinflammatory drugs in children with varicella are insufficient. When necrotizing fasciitis is suspected, prompt surgical drainage, debridement, fasciotomy, or amputation often is necessary. Many experts recommend intravenously administered penicillin G and clindamycin for the treatment of invasive GABHS infections on the basis of animal studies. Some evidence exists that intravenous immunoglobulin given in addition to appropriate antimicrobial and surgical therapy may be beneficial. Although chemoprophylaxis for household contacts of persons with invasive GABHS infections has been considered by some experts, the limited available data indicate that the risk of secondary cases is low (2.9 per 1000) and data about the effectiveness of any drug are insufficient to make recommendations. Because of the low risk of secondary cases of invasive GABHS infections in schools or child care facilities, chemoprophylaxis is not indicated in these settings. Routine immunization of all healthy children against varicella is recommended and is an effective means to decrease the risk of invasive GABHS infections.

Necrotizing fasciitis is an overwhelming infection common to the perineum, abdominal wall, and extremities. It is a surgical emergency related to a high mortality rate that is more often seen in elderly and immunocompromised patients. Necrotizing fasciitis occurs uncommonly in the head and neck region. Over a 12-year period, 47 cases of necrotizing fasciitis of the head and neck region were collected at this hospital. The demographics, predisposing factors, clinical presentation and courses, management, complications, and outcomes were analyzed. The cases were divided into two groups: survivors and nonsurvivors. Statistical comparisons were made of the parameters age, gender, smoking or drinking habit, underlying medical problems, laboratory data, and treatments used. Forty-two patients (89.4 percent) had associated systemic disease; most of these patients had diabetes (72.3 percent). The clinical manifestations are nonspecific but are often typical for diagnosis. The necessity of computed tomographic scans is not conclusive in this study. Presentation of septic shock (p = 0.004) and association with underlying malignancy (p = 0.03) were the only statistically significant factors that led to a poor prognosis. The cornerstones of proper management include early diagnosis, aggressive surgical debridement, broad-spectrum antibiotics, and intensive supportive care.

A case of lethal invasive mucormycosis (IM), a rare fungal infection which predominantly affects immunocompromised patients, is reported in a 73-year-old female patient who presented with a cervical abscess. The patient had asthma treated with steroids and had previously undiagnosed diabetes mellitus. Despite surgical treatment and parenteral antibiotic therapy, there was fatal progression of the condition. The pathogenesis, histological appearances and treatment of mucormycosis are discussed, particularly the importance of urgent histological examination of debrided tissue to distinguish this condition from necrotizing fasciitis (NF) earlier than microbiological culture alone would allow, thus permitting the early introduction of appropriate antifungal therapy.

Between January 1992 and December 1998, we treated 24 patients with necrotising fasciitis of a limb. There were 15 men and nine women with a mean age of 59.8 years (5 to 86). The infection was usually confused with cellulitis. Exquisite pain and early systemic toxicity were the most consistent clinical features. Diabetes mellitus and hepatic cirrhosis were the most commonly associated medical diseases. One third of the patients died. Those with involvement of the limbs above the knee or elbow on admission had a significantly higher rate of mortality than those with distal lesions (Fisher's exact test, p = 0.027). There was no correlation between mortality and advanced age (Student's t-test, p = 0.22) or between amputation and survival (Fisher's exact test, p = 0.39).

Necrotising fasciitis is a severe life threatening bacterial infection of the fascial planes which is relatively rare in the head and neck region. The hallmark of the disease is selective necrosis of the fascia overlying skin and adjacent vasculature. Primary odontogenic infection due to aerobes and obligate anaerobes and trauma amongst other factors, are frequently responsible for this condition. Similarly, affected individuals often have an underlying systemic disease, the most common of which is diabetes mellitus. Treatment usually involves appropriate antimicrobial therapy, control of systemic disease, thorough surgical debridement, gamma globulin administration and hyperbaric oxygen where facilities exist. Significant morbidity and mortality attends necrotising fasciitis when treatment is delayed due to toxaemia, dehydration and severe biochemical disturbances. Prompt diagnosis, adequate resuscitation, thorough and frequent surgical debridement remains the cornerstone to a successful outcome.

Fournier's gangrene, a form of necrotizing fasciitis, is an uncommon, fulminant, rapidly progressing subcutaneous infection of the scrotum and genito-perineal region, and may occur in all age groups. Most cases involve a mixed synergistic infection of aerobic and anaerobic bacteria, and occur as a result of one of this mechanisms: local trauma, extension from a perineal, periurethral or ischiorectal infection. It is associated with a high mortality rate. Predisposing factors included diabetes mellitus, steroids or chemotherapy, alcohol abuse, malignancy and radiation therapy. This disease requires prompt treatment: early diagnosis, antibiotic therapy, nutritional support, immediate extensive surgical debridement and hyperbaric oxygen therapy. The use of etherologue serum is a valuable adjunct in the therapy of Fournier's gangrene. We report a case of Fournier's syndrome treated with etherologue serum immuno-therapy, together with the conventional multidisciplinary approach. The postoperative course was uneventful and the patient was discharged on day 50 post intervention in good general conditions. The 3 years follow-up showed no recurrence of the disease. In conclusion we remark that the survival can be improved in patients with Fournier's gangrene by multidisciplinary approach.
