Necrotizing fasciitis most often occurs in the context of prior trauma or surgery. Predisposing medical conditions include diabetes mellitus, arteriosclerosis, obesity, hypertension and prior irradiation. De novo occurrence in the vulva, in the absence of prior injury, surgery or irradiation, has been reported rarely. Necrotizing fasciitis of the vulva in the diabetic patient may have an insidious onset but requires an early diagnosis and aggressive surgical episode of fasciitis occurred in an obese, diabetic woman. Aggressive, wide excision of all infected vulvar, mons and thigh tissue, followed by aggressive medical and surgical postoperative care, resulted in minimal morbidity. Prompt recognition and aggressive care are required to treat this condition.

Scleroderma developed in six women who were taking L-tryptophan. Fasciitis and morphea were most common, but one patient had pleural effusion, hypertension, and signs of cardiac and kidney failure. In five patients the biopsy findings were characteristic of scleroderma; the sixth patient had Crohn's disease and developed fasciitis; her biopsy specimen showed inflammatory arteritis. All patients' conditions improved after cessation of their L-tryptophan intake, initiation of corticosteroid therapy, or both. These findings confirm previous data that show altered tryptophan-kynurenine metabolism in some patients with scleroderma and fasciitis, particularly with tryptophan loading.

Since 1986, we have cared for 17 patients whose abdomen could not be closed because of bowel edema and loss of abdominal wall compliance. These patients were managed by a technique of visceral packing with the intestines kept in place by a combination of rayon cloth, gauze packs, and retention sutures. This packing was changed in the operating room under general anesthesia until the edema was sufficiently resolved to allow for closure. Two patients died within 24 hours of operation from irreversible shock. The remaining 15 patients had their fascia successfully closed with an average of two additional anesthetics. There was one case of fasciitis associated with the development of an intra-abdominal abscess and one patient died of late sepsis. There was no early postoperative ventilatory compromise or acute oliguric renal failure. Other direct complications have been minor with no enterocutaneous fistulae, dehiscence, or incisional hernia. Visceral packing of posttraumatic abdominal wounds circumvents expected complications of intraperitoneal hypertension and enhances the chance for survival. Its ease and low morbidity also lends itself to a wide variety of other uses.

Morbidity from wound healing was retrospectively analyzed in a series of 202 consecutive patients with tumors of the soft tissue of the extremities, torso and head and neck region who were treated with preoperative irradiation and conservative operation at the Massachusetts General Hospital between January 1971 and June 1989. A radiation boost dose was given to 143 patients (71 percent) postoperatively. The overall wound complication rate was 37 percent. One patient died because of necrotizing fasciitis. In 33 instances (16.5 percent), secondary operation was necessary, including six patients (3 percent) who required amputation. The wounds in the remaining 40 patients (20 percent) were treated without operation. Multivariate analyses of the data showed the factors that were significantly associated with wound morbidity: tumor in the lower extremity (p < 0.001), increasing age (p = 0.004) and postoperative boost with interstitial implant (p = 0.016). Accelerated fractionation (BID, two fractions per day) reached borderline statistical significance (p = 0.074). Two other factors showed association with wound morbidity by univariate analysis, but not in multivariate model: high pathologic grade (p = 0.02) and estimated volume of resected specimen > or = 200 milliliters (p = 0.065). Patient gender, intercurrent disease (diabetes or hypertension), obesity, maximal tumor size, primary versus recurrent tumor, duration of bed rest postoperatively, dose of postoperative boost radiation, the use of postoperative boost, the use of adjuvant chemotherapy and year of treatment did not show significant importance for wound morbidity. When the severe wound complications (defined as requiring secondary operation and including the patient who died because of necrotizing fasciitis) were considered, among all analyzed variables, only localization of tumor in the lower extremity as a single factor was significant (p < 0.001). Techniques for managing the wound are considered which are judged likely to contribute to a decrease of the incidence of wound healing delays.

The following risk factors, previously associated with necrotizing fasciitis, were identified in 25 consecutive patients: diabetes mellitus, intravenous drug abuse, age greater than 50, hypertension, and malnutrition/obesity. Additional data recorded included the duration of illness to the time of the first operative procedure, the type of procedure performed, the anatomic location of the infection, the etiology, culture reports, and leukocyte counts. The goal of this study was to determine whether the number of risk factors present in a patient was predictive of mortality. Six patients (24%) died and 19 patients survived. The nonsurvivors exhibited a significantly higher percentage of diabetes mellitus, 83 per cent versus 37 per cent (P = 0.047). Fifteen of 19 survivors (79%) and only one of six nonsurvivors (17%) had fewer than three risk factors (P = 0.006). In conclusion, more than three previously identified risk factors present in patients with necrotizing fasciitis were found to be predictive of a mortality rate of 50 per cent. The mainstay of treatment remains aggressive surgical intervention, broad-spectrum antibiotics, and nutrition support.

A 35-year-old man with idiopathic eosinophilic fasciitis (EF) and morphea developed renal disease characterized by microscopic hematuria, nephrotic range proteinuria, and rapidly progressing hypertension, an association that has not previously been reported in EF. Initial clinical symptoms of EF began in July 1989; peripheral eosinophilia peaked at 30% in August 1990; an abnormal urinalysis was first observed in March 1992 and subsequently a renal biopsy was performed. Renal biopsy demonstrated focal segmental glomerulosclerosis and a subepithelial immune-type deposit. Partial fasciectomy and a course of methotrexate resulted in overall functional improvement of his extremities. Proteinuria and hematuria was reduced during methotrexate therapy.

There are some racial differences in the prevalence and prognosis of idiopathic nephrotic syndrome; however, reports about minimal change disease (MCD) in Chinese were rare. We retrospectively analyzed 123 Chinese adults with idiopathic nephrotic syndrome, who received percutaneous renal biopsy in our institution within the last 10 years. In total, 46 patients (37.4%) were compatible with the pathological diagnosis of MCD. The male to female ratio was 1.2:1. The mean age of onset was 30.9 years, and 80% of the patients with MCD were less than 40 years. The mean daily proteinuria was 10.2 g, and serum albumin was 1.8 mg/dl. Azotemia occurred in 16 (35%) of 46 cases; hypertension, 13%; and microscopic hematuria, 13%. High selectivity index for proteinuria (SI <0.1) was noted in 12 (39%) of 31 cases; and high IgE level was found in 83.7% of the study subjects, although only one case had allergic history. Complete remission in 36 MCD patients treated with corticosteroid was achieved by 42% (15/36), 80% (29/36), and 94% (34/36) within 4, 8, and 12 weeks, respectively. The time interval to remission was similar between the younger group (<40 years old, 1.7 months) and older group (>40 years old, 1.6 months). Nineteen (56%) of 34 cases with steroid response did not relapse, and the other cases (44%) had a mean relapse rate of 1.5 times per patient within a period of 45 months. The age of onset in MCD cases was not significantly correlated with steroid-responsive rate, and the time interval to remission. However, a tendency existed between the onset in the young age and the sequentially relapsing rate (p = 0.06). Two cases with primary steroid resistance and 5 cases with frequent relapse or steroid dependence responded well to intravenous pulse therapy of cyclophosphamide, except one refractory case. No thrombotic episode was ever noted in our group. Regarding infectious complications, primary peritonitis occurred in one, pneumonia in one, and cellulitis in 6 cases during active nephrotic stage. Two mortality cases, one with E. coli-related necrotizing fasciitis and one from pneumonia, were noted. In brief, compared with children, adult patients with MCD had lesser high selectivity index for proteinuria, the same steroid-responsive rate (94%), but slower response, and significantly lesser relapsing rate. The intravenous pulse therapy of cyclophosphamide may be an alternative regimen for adult patients with steroid resistance or dependency. In addition, the Asian adult-onset MCD had younger age, male predominance, and lesser relapsing rate in comparison to those of the Western population.

Polyarteritis nodosa (PAN) is a necrotizing arteritis of small and medium-sized vessels. It may present with hypertension and/or renal insufficiency. Peripheral neuropathy, myopathy, joint pains, testicular pain, and ischemic myalgias may also be seen. Gastrointestinal involvement may lead to gangrene of the bowel, peritonitis, perforation, intra-abdominal hemorrhage, and pancreatitis. The cutaneous manifestations include tender subcutaneous nodules grouped along the course of superficial arteries of the lower extremities, with or without an overlying livedo reticularis. Although multisystem involvement is characteristic, sometimes only one organ or system may be involved. Associations with viral hepatitis (both B and C) and streptococcal infection have been established for PAN. Recurrent strep infections of the upper respiratory tract, streptococcal glomerulonephritis and rheumatic fever have previously been linked to PAN. This report extends the spectrum of associated streptococcal infections to include necrotizing fasciitis.

Sixteen cases of necrotizing fasciitis were seen at the Obafemi Awolowo University Teaching Hospital, Ile-Ife, Nigeria from 1990 to 2000. Primary craniocervical involvement was recorded in seven patients (five men and two women). The clinical records of five patients were sufficiently detailed to allow us to report their age, aetiology, predisposing illness, clinical features, complications, management regimen and outcome. The patients were aged 30-75 years and in four of them odontogenic infections were the cause of the condition. Hypertension, diabetes mellitus and obesity were the underlying systemic diseases in three cases and the body/angle region of the mandible was the predominant site of the infection on the face. All five cases had involvement of the neck. Mediastinal extension was recorded in three cases. Two patients had complications: one had septicaemia and renal failure and the other developed bone necrosis. Pre-existing ill health, old age, late surgical intervention, and mediastinal and thoracic extension of infection were responsible for the only death. Treatment involved frequent and multiple surgical debridement, aggressive antimicrobial treatment and control of systemic disease. Early recognition, prompt surgical intervention, and aggressive antimicrobial treatment are essential to minimize morbidity and mortality. Rapid progression of infection, financial constraints, delayed referrals from rural clinics and distance to the tertiary hospital caused problems.

Fournier's gangrene is an infectious necrotizing fasciitis of the perineum and genital regions. It is a synergistic infection caused by a mixture of aerobic and anaerobic organisms. The mortality rate from this infection ranges from 0 to 67 per cent. One of the most important determinants of overall outcome is early recognition and extensive surgical debridement upon initial diagnosis. This is followed by aggressive antibiotic therapy combined with other precautionary and resuscitative measures. Our hypothesis is that early aggressive surgical debridement combined with broad-spectrum antibiotic coverage results in decreased mortality from Fournier gangrene. The objective of this study was to determine our morbidity and mortality as compared with other institutions. This was a retrospective review of 200 charts of patients from 1990 through 2001. The charts reviewed included patients with a diagnosis of male and female genital abscesses, cellulitis, necrotizing fasciitis, and vascular disorders. This resulted in 33 patients who had a final diagnosis of Fournier's gangrene. There were 26 (79%) males and seven (21%) females with a diagnosis of Fournier's gangrene. The patients ranged in age from 30 to 85 years (mean age 51.5). There were a number of predisposing factors that were examined. Thirteen patients (39%) were diabetic, 18 (55%) suffered from hypertension, 18 (55%) were obese, and 18 (55%) were cigarette smokers. Four patients (12%) had no predisposing factors. The treatment consisted of wide surgical debridement which was performed in all 33 patients. Most patients received multiple debridements ranging from one surgery to seven (mean 3.25) per hospital stay. The majority of patients received broad-spectrum antibiotic coverage. Three patients died, which resulted in a mortality rate of 9 per cent. Early recognition and aggressive surgical debridement is the most essential intervention in stopping the rapidly progressing infectious process of Fournier's gangrene. This intervention should be combined with aggressive triple-antibiotic therapy and other precautionary measures for supporting the patient who has the systemic effects of Fournier's gangrene. Our data do not reach statistical significance with regard to the use of triple-antibiotic therapy. However, we believe that it is an important part of the treatment regimen. The combination of aggressive surgical therapy and appropriate antibiotic coverage results in a reduction in mortality.
