Necrotizing soft tissue infection is an uncommon and severe infection of the skin, subcutaneous tissue and superficial fascia which is usually accompanied by severe systemic toxicity. These infections occur more frequently in diabetics and are associated with higher morbidity and mortality rate. The prognosis of necrotizing fasciitis is known to be dependent on early recognition and treatment. Therefore, clinical awareness is important to avoid fatal outcome in patients with diabetes mellffus. We present three patients with undiagnosed type 2 diabetes in whom hyperglycaemia may have facilffated me development of necrotizing tissue infection, which in tum may have precipitated diabetic ketoacidosis in patients who rarely develop this metabolic complication.

A 50-year-old woman with a 15-year history of type 2 diabetes mellitus was admitted to our hospital due to high fever and a skin lesion with severe pain, swelling and a sensation of heat in the right thigh. Laboratory examination showed elevated C-reactive protein (CRP), thrombocytopenia, nephrotic syndrome and renal dysfunction. Her blood glucose level had been well controlled. Streptococcus agalactiae was detected in both the skin lesion and blood culture, and pathological examination revealed neutrophil infiltration in the fascia and muscle layer. The patient was diagnosed with necrotizing fasciitis, septic shock and disseminated intravascular coagulation. A combination therapy of antibiotics and surgical debridement resulted in the improvement of symptoms as supported by laboratory findings, and the skin lesion also showed improvement. Although group A streptococcus is well known to be implicated in the pathogenesis of necrotizing fasciitis, only S. agalactiae, belonging to group B streptococcus, was isolated from the tissue and blood cultures in this case. Although this organism is not virulent and rarely causes a necrotizing fasciitis, both the superficial fascial layer and underlying muscle were affected in this case. There have been only a few reports of necrotizing fasciitis due to S. agalactiae in patients with diabetes mellitus. Although the blood glucose level was well controlled in our patient, this disease might be caused by other factors, including diminished sense of touch and pain, abnormality of microcirculation and hypogammaglobulinemia due to nephrotic syndrome.

Calciphylaxis-induced chronic wounds are difficult to heal. The value of vacuum-assisted closure (VAC) was assessed in two patients with calciphylaxis. Two middle-aged females with type 2 diabetes were transferred to the burn unit with a clinical diagnosis of necrotizing fasciitis, although the pathologic diagnosis was calciphylaxis. With extensive debridement, antibiotics, and meticulous wound care, one patient had progressive necrosis of her skin from 18 to 48% TBSA, whereas the other progressed from 5 to 10% TBSA only. The patient with the smaller chronic wound healed well and left the hospital at 72 days after admission. Although there was some success with the use of VAC, the patient with the extensive progressive wounds developed a fungal wound infection that did not respond to treatment; she died 78 days after initiation of burn center treatment. Some disadvantages to the usefulness would be extensive contiguous wounds and the lack of an intact skin surface. The VAC system was of value in healing wounds resulting from calciphylaxis.

A 52-year-old man was given a diagnosis of type 2 diabetes mellitus at age 39. At age 46, he stopped taking medication. Two weeks after burning his legs at low temperature, he fell, using his right arm to protect his legs. The next day, he complained of pain and slight swelling from his right shoulder to his anterior chest and came to our hospital. At that time, a plain computed tomography scan suggested gasogenic bacterial infection and we discussed the indications for debridment. Although his widespread inflammation required extensive treatment including thoracostomy, we abandoned surgical treatment and administered several antibiotics in appropriate combination because of his severe condition. After admission, the mass grew rapidly and it was diagnosed as necrotizing fasciitis based on percutaneous needle biopsy and clinical findings. Although both inflammatory reactions and mass size tended to improve, he had repeated recurrence of pain and swelling in his right anterior chest. When he had a second recurrence, he received additional short-term steroid therapy. Afterwards he had no further recurrence. In this case, early clinical diagnosis, using broad-spectrum antibiotics prior to definite diagnosis, and additional short-term steroid therapy at the time of the recurrence were effective.

A patient with a history of type II diabetes mellitus (DM), end stage renal disease (ESRD), and congestive heart failure (CHF) developed necrotizing fasciitis caused by Serratia marcescens after scraping his leg on rocks in a river while fishing. Aggressive management with surgical debridement, antibiotics, and pressure support was unsuccessful.

Necrotizing fasciitis is a soft tissue infection characterized by necrosis of fascia and subcutaneous tissue. It frequently involves the groin, abdomen and lower extremities, but rarely involves the head and neck region. An unusual occurrence of periorbital necrotizing fasciitis after a routine endoscopic sinus surgery in a 57-year-old woman with a history of type II diabetes mellitus is presented. Although the disease is very rare, all the physicians should be aware of the manifestations of this disorder and its treatment. Early recognition and prompt intervention plays an important role in minimizing the morbidity and mortality rates.

Necrotizing fasciitis is a soft-tissue infection characterized by extensive necrosis of subcutaneous fat, neurovascular structures, and fascia. In general, fascial necrosis precedes muscle and skin involvement, hence its namesake. Initially, this uncommon and rapidly progressive disease process can present as a form of cellulitis or superficial abscess. However, the high morbidity and mortality rates associated with necrotizing fasciitis suggest a more serious, ominous condition. A delay in diagnosis can result in progressive advancement highlighted by widespread infection, multiple-organ involvement, and, ultimately, death. We present a case of limb salvage in a 52-year-old patient with type 2 diabetes mellitus and progressive fascial necrosis. A detailed review of the literature is presented, and current treatment modalities are described. Aggressive surgical debridement, comprehensive medical management of the sepsis and comorbidities, and timely closure of the resultant wound or wounds are essential for a successful outcome.

The purpose of this retrospective case report was to describe the results of negative pressure wound therapy (NP WT) in the treatment of wounds of various size, location and etiology in four patients. The effects of NP WT were assessed in the following patients. 1) A 68-year-old male diagnosed with cellulitis presenting with two open wounds on the left foot; 2) a 60-year-old male diagnosed with Type II diabetes mellitus presenting with a full thickness wound on the plantar surface of the right foot; 3) a 64-year-old male diagnosed with necrotizing fasciitis, diabetes mellitus, and Crohn's disease presenting with a left gluteal wound; and 4) a 47-year-old obese female diagnosed with necrotizing fasciitis presenting with a wound of the right groin and buttock. All wounds were debrided of devitalized tissue and contained nearly 100% granulation tissue prior to NPWT treatment. NPWT was applied three times per week, each application lasting 48 hrs, followed by dressing change, cleaning of the wound bed and continued debridement as required. Treatment duration, varying from 4-9 weeks, corresponded to the patient's length of stay at the sub-acute rehabilitation facility, and pressure settings ranged from 100 to 200 mmHg. Measurements of wound length, width, depth and appearance were recorded once a week. Follow-up was conducted 6-18 months post treatment to assess self-reported wound status. NPWT resulted in reductions of wound length, width, and depth, with the greatest reduction in each case being wound depth. Reduction in wound depth ranged from 75-100% (100% being complete wound closure), with four of the five wounds exceeding 90%. Reduction in wound length ranged from 32-100%, with three wounds exceeding 80%, and reduction in wound width ranged from 35-100%, with three wounds exceeding 80%. Three wounds closed completely either during therapy or soon (2-4 weeks) thereafter, and two wounds were reduced in size sufficiently for treatment via skin grafts. NPWT, applied to wounds of diverse size, location, and etiology, resulted in reductions in wound length, width, and depth in four patient cases, with the greatest influence of reducing wound depth.

Necrotizing fasciitis is an uncommon manifestation of Salmonella infection. We report a case of Salmonella group D septic arthritis complicated with necrotizing fasciitis in a 51-year-old man who had noninsulin dependent diabetes mellitus and rheumatoid arthritis. He presented with fever and severe right hip pain complicated with septic shock and disseminated intravascular coagulation. Crepitation was noticed upon physical examination, and plain films showed numerous air bubbles in the soft tissue around the hip joint. Prompt antibiotic therapy and surgical management were performed with a successful response. The causative organism was Salmonella group D. Antibiotic was given in the total course of 3 months, and there was no relapse of salmonellosis after 2 years follow up. The differential diagnosis of causes of non-clostridial crepitant soft tissue and muscle infections must include Salmonella, especially in patients who have underlying diseases or are taking immunosuppressive drugs. Prompt management is needed to reduce mortality and morbidity. Long-term suppressive therapy may be needed to prevent relapse.

The necrotizing fasciitis is a life threatening disease, since its mortality reaches 30-35%, in different studies. In diabetic patients, the incidence and severity of this illness are even higher. The authors present a series of 39 diabetic patients with necrotizing fasciitis of the leg, which were operated between 2001 and 2006 in the Surgical Department of "Dr. I. Cantacuzino" Clinical Hospital, from Bucharest. It is emphasized the importance of a complete diagnosis and the surgical treatment of all the suppurative processes. Sometimes, more than one procedure is required, in order to achieve this goal. In our series, 20 patients needed one operation, while 19 were operated for several times (2-6). The mortality rate was 20.6% and the average length of stay--22.6 days. It is presented the case of a 61 years male, with an unbalanced type II diabetes mellitus and an extensive necrotizing fasciitis of the thigh. The therapeutic attitude consisted in 6 consecutive surgical procedures (drainage, necrosectomy, large fasciectomy), which allowed a favourable evolution and the healing of the patient.
