Necrotizing fasciitis associated with malignancy

Fatal Clostridium septicum gas gangrene complicating ECMO: case report and review of literature

Clostridium septicum gas gangrene is a severe and deadly infection caused by an anaerobic, spore-forming, Gram-positive bacillus. As previously described, two entities are observed: traumatic and spontaneous (or non-traumatic) forms. In this report, we aim to describe the case of a fulminant and ultimately fatal C. septicum myonecrosis occurring in a patient who was first admitted for refractory cardiac arrest and placed on veino-arterial extracorporeal membrane oxygenation (ECMO). Building upon prior studies that have documented cases of spontaneous gas gangrene caused by C. septicum, we provide an updated compilation, focusing on microbiological characteristics of C. septicum, along with the diagnostic and therapeutic challenges associated with spontaneous gas gangrene. Additionally, the specific clinical situation of our case illustrates the seriousness of this infectious complication that combined both spontaneous and traumatic gas gangrene risk factors. We thus, discuss the antibiotic coverage prior to the initiation of ECMO procedure.

Necrotizing Fasciitis Co-existing With Oral Squamous Cell Carcinoma: A Case Report of a Diagnostic Dilemma

Necrotizing fasciitis is an uncommon yet highly dangerous bacterial infection characterized by rapid spread along the fascial planes and subcutaneous tissue, leading to extensive tissue necrosis and often resulting in death. The swift progression of necrosis can induce systemic sepsis, toxic shock syndrome, and multi-organ failure. While necrotizing fasciitis of the neck is rare, it typically originates from dental or pharyngeal sources. Successful treatment hinges on early diagnosis, appropriate antibiotic therapy, and surgical intervention for tissue debridement. This article presents the case of a 40-year-old individual with necrotizing fasciitis of the neck. We herein review the clinical features, pathogenesis, and treatment approach for the case. Rapid recovery necessitated comprehensive medical treatment targeting the underlying cause with aggressive supportive measures. Surgical intervention involved thorough debridement to remove necrotic tissue, irrigation with antiseptic solutions, and early application of topical antimicrobials.

Necrotizing Fasciitis of the Upper Extremity - A Review

Necrotizing fasciitis is a soft tissue infection that habitually originates from the fascial sheaths, expands at a volant pace, leads to extensive necrosis of the subcutaneous tissues, and eventually ends up in a life-threatening condition with notably elevated amputation and mortality rates. Factors that induce interruption of skin integrity, such as trauma or intravenous drug use, are the most common inciting events. Specific clinical signs heralding its presence are usually absent in the early stages, often resulting in misdiagnosis. Early recognition, prompt and aggressive surgical debridement, antibiotic use, and supportive care constitute the fundamental principles to lean on for a better prognosis. Necrotizing fasciitis of the upper extremity is relatively rare and consequently holds a limited place in the literature. Only a few studies assess it as a separate entity, with most of them being case reports or small case series. We, therefore, performed a review of the current literature, to assemble the dispersed results of different studies and clarify the various aspects of upper limb necrotizing fasciitis. In this systematic review, we present the epidemiological data, the causative events, the most frequent underlying diseases, the risk factors, the amputation and mortality rates, the pathogenic microorganisms, the clinical characteristics, the diagnostic tools, the medical and surgical management concerning necrotizing fasciitis of the upper limb. Finally, the results indicating its differentiation compared to necrotizing fasciitis of other anatomic sites are remarkably highlighted.
