Conclusion FG is a rare necrotizing fasciitis of the perineal, genital and perianal region with an aggressive clinical course. Although rare, necrotizing fasciitis due to Candida species as well as Lactobacillus gasseri has also been reported [ Tleyjeh et al. Agngrena LRINEC score of more than 6 should raise the suspicion of necrotizing fasciitis among patients with severe soft tissue infections, and a score greater than 8 is strongly predictive of FG.

Moreover, the authors found that its application may prove most useful in patients with extensive and contaminated penoscrotal defects [ Lee et al. Although the condition is infrequent, the high associated health care costs suggest that primary and secondary prevention measures should be implemented.

Continuing navigation will be considered as acceptance of this use. NPWT can be used in wound management utilizing the lower limit of pressure, which is recommended to be between 50 and mmHg. The laboratory values most often predictive of worse prognosis include increased leukocyte counts, creatinine, creatine kinase, urea, lactate dehydrogenase, alkaline phosphatase, and decreased levels of hematocrit, bicarbonate, sodium, potassium, calcium, total protein and albumin [ Clayton et fohrnier.

Loose wound edge closure was achieved with a nonabsorbable monofilament suture by U-stitch approximation of the scrotal or perineal wound edges [ Akilov et al. Ann R Coll Surg Engl VAC therapy works by exposing a wound to subatmospheric pressure for an extended period to promote debridement and healing Figure 2 [ Mallikarjuna et al.

Moreover, a drain was left in place to allow for irrigation of the graft with Sulfamylon for the first 5 days. In patients infected with methicillin-resistant S.

Urologic sources of FG include urethral strictures, chronic urinary tract infection, neurogenic bladder, epididymitis and recent instrumentation [ Amendola et al. Based on analysis of individual comorbid conditions, only ischemic heart disease displayed a statistically significant association with mortality due to Fournier gangrene; ischemic heart disease was also associated with longer hospital stay.

fisiopatologka Overall, US is considered superior to conventional radiography as soft tissue air is more obvious and scrotal contents along with Doppler blood flow can be examined. Each patient underwent application of a 2: Excellent wound coverage and functional outcome was achieved in the seven patients who underwent reconstruction with this approach. Singapore Med J Treatment of FG entails treating sepsis, stabilizing medical parameters and urgent surgical debridement.

Conclusions Fournier gangrene is associated with high mortality despite appropriate early treatment. Topical therapy After initial radical debridement, open wounds are generally managed with sterile dressings or negative-pressure wound therapy. Moreover, the flap was found to be less bulky than a gracilis flap with minimal donor site morbidity [ Ganggena et al. Please review our privacy policy.

Specifically, the authors found that the pudendal thigh fasciocutaneous flap, a flap based on the terminal branches of the superficial perineal artery, is indicated for reconstruction of perineal defects with good functional and cosmetic outcomes. The physiological effects are believed to be enhanced leukocyte ability to kill aerobic bacteria, stimulation of collagen formation and increased levels of superoxide dismutase resulting in better tissue survival.

Mainstays of treatment include rapid and aggressive surgical debridement of necrotized tissue, hemodynamic support with urgent resuscitation with fluids, and broad-spectrum parental antibiotics. The diagnosis is often made clinically, although radiography can be helpful when the diagnosis or the extent of the disease is difficult to discern.

Other organisms like Bacteroides inhibit the phagocytosis of aerobic bacteria, aiding in further spread of the infection [ Morua et al.

Arch Esp Urol The presence of severe sepsis on admission has been significantly associated with mortality [ Kara et al. Lee and colleagues described the use of unilateral gracilis muscle flap reconstruction combined with the internal pudendal artery perforator flap for reconstruction of extensive penoscrotal defects.

The incident leading to the inoculation may be so trivial that the patient or physician may fail to notice. Pol J Microbiol The aim of this study was to analyze the epidemiological and clinical characteristics of Fournier gangrene along with the variables that influence disease course and mortality in patients treated in our department.
