ABSTRACT Necrotizing fasciitis is a rare but life-threatening soft-tissue infection characterized by rapidly spreading inflammation and subsequent necrosis of the fascial planes and surrounding tissue. Infection typically follows trauma, although the inciting insult may be as minor as a scrape or an insect bite. Often caused by toxin-producing, virulent bacteria such as group A streptococcus and associated with severe systemic toxicity, necrotizing fasciitis is rapidly fatal unless diagnosed promptly and treated aggressively. Necrotizing fasciitis is often initially misdiagnosed as a more benign soft-tissue infection. The single most important variable influencing mortality is time to surgical débridement. Thus, a high degree of clinical suspicion is necessary to avert potentially disastrous consequences. Orthopaedic surgeons are often the first to evaluate patients with necrotizing fasciitis and as such must be aware of the presentation and management of this disease. Timely diagnosis, broad-spectrum antibiotic therapy, and aggressive surgical débridement of affected tissue are keys to the treatment of this serious, often life-threatening infection.

ABSTRACT: Klebsiella pneumoniae necrotizing fasciitis is a rare infection in regions outside of Asia. Here, we present a case of necrotizing fasciitis of the leg caused by K. pneumoniae in a 92-year-old French woman hospitalized in a geriatric rehabilitation unit. The patient initially presented with dermohypodermitis of the leg that developed from a dirty wound following a fall. A few hours later, this painful injury extended to the entire lower limb, with purplish discoloration of the skin, bullae, and necrosis. Septic shock rapidly appeared and the patient died 9 hours after the onset of symptoms. The patient was Caucasian, with no history of travel to Asia or any underlying disease. Computed tomography revealed no infectious metastatic loci. Blood cultures showed growth of capsular serotype K2 K. pneumoniae strains with virulence factors RmpA, yersiniabactin and aerobactin. This rare and fatal case of necrotizing fasciitis caused by a virulent strain of K. pneumoniae occurred in a hospitalized elderly woman without risk factors. Clinicians and geriatricians in particular should be aware of this important albeit unusual differential diagnosis.Clinical Interventions in Aging 07/2014; 9:1171-4.

ABSTRACT: Fournier's gangrene is a rare but rapidly progressive necrotizing infection that results from the synergistic action of multiple aerobic and anaerobic organisms colonized on the skin and in the anogenital area. This is a case report of a middle-aged man with late presentation of Fournier's gangrene that was treated aggressively by a team of infectious disease specialists, surgeons, intensivists, and intensive care unit specialty nurses over a 3-week period. Despite heroic efforts by the multidisciplinary team, the patient's condition deteriorated and he died of multisystem failure. The purpose of this article was to alert clinicians to the etiology, pathophysiology, risk factors for invasive necrosis, prognostic indicators, and current diagnostic and treatment recommendations. Fournier's gangrene represents a true medical and surgical emergency and requires early recognition and a team approach to management.Critical care nursing quarterly 04/2015; 38(2):143-53.
