Necrotizing Myositis: A Rare Necrotizing Soft Tissue Infection Involving Muscle.

INTRODUCTION: Necrotizing myositis (NM) is an extremely rare necrotizing soft tissue infection involving muscle. Unlike similar infections (eg, necrotizing fasciitis, clostridial myonecrosis) that can be more readily diagnosed, NM can have a benign presentation then rapidly progress into a life-threatening condition with a mortality rate of 100% without surgical intervention. CASE REPORT: A 74-year-old man with a history of prostate cancer with radiation therapy, seed implants, and 2 transurethral resection procedures presented to the emergency department after a fall. He was initially diagnosed and treated for urosepsis. Sixteen hours after presentation, he complained of pain and swelling of his right groin. Computed tomography of the abdomen and pelvis showed gas findings suspicious for necrotizing infection of the bilateral thighs. Surgical exploration revealed NM. Separate cultures from the left thigh and bladder grew Streptococcus intermedius, Clostridium clostridioforme, and Peptostreptococcus, suggesting a possible common source of infection from the prostate gland or the osteomyelitic pubic symphysis, which subsequently spread to the bilateral thighs. CONCLUSIONS: To the best of the authors' knowledge, this is the first reported case of S intermedius and C clostridioforme causing NM. A high index of suspicion is required for extremely rare conditions like NM, because early diagnosis and surgical intervention significantly reduce mortality.

Hyperbaric oxygen therapy as adjuvant therapy in necrotizing fasciitis of the face: case report.

Facial necrotizing fasciitis is a rare bacterial infectious disease. Rapid necrosis of the tissues and suppurative fasciitis is pathognomonic. It can be seen following odontogenic infection. Early aggressive debridements and wide-spectrum antibiotic therapy are currently accepted treatments. A 60-year-old man was admitted to the otolaryngology clinic for facial pain and swelling after odontogenic infection. Inflamed left maxilla and orbit were seen, and abscess contents spontaneously drained into the mouth. It was determined that infectious markers were increased in the blood. On MRI, a broad abscess with edema and gas formation was seen. Debridement of the necrotic tissue was performed immediately and wide-spectrum antibiotic therapy was started. Infection was stopped and wound was closed, with four weeks of antibiotic therapy, three sessions of debridement, and 30 sessions of hyperbaric oxygen (HBO2) therapy. HBO2 therapy must not replace the combination of early aggressive debridements and wide-spectrum antibiotic therapy, but rather must be considered as an important adjuvant treatment.

Necrotizing fasciitis associated with acupuncture: a case report.

Infectious complications from acupuncture are extremely rare; we present a case of severe necrotizing Fasciitis (type 1) in an elderly nondiabetic male.

Surgical debridement and adjunctive hyperbaric oxygen in cervical necrotizing fasciitis.

OBJECTIVE: To review our management of cervical necrotizing fasciitis (CNF) with the use of adjunctive hyperbaric oxygen therapy (HBO). STUDY DESIGN: Case series with chart review. SUBJECTS AND METHODS: Evaluation of ten patients with CNF between 2001 to 2006. RESULTS: There were five male and six female patients. Mean age was 43 +/- 11 years. Eight cases resulted from an odontogenic source. Comorbidities included diabetes mellitus, hypertension, and substance abuse. All patients had computed tomography scans performed, received intravenous antibiotics, and underwent surgical debridement. Eight patients underwent surgery within 24 hours. The average number of debridements was 2.2 +/- 0.8. Hospitalization was twice as long for diabetic patients (15.5 +/- 8.16 days) compared with nondiabetic patients (7.5 +/- 1.6 days, P = 0.029). Nine patients had HBO therapy. Combined data revealed a possible decrease in length of hospitalization with HBO therapy (P < 0.001). No mortality was documented. CONCLUSION: In addition to early and aggressive medical management and surgical debridement, this study suggests that HBO therapy is a beneficial adjunct by potentially decreasing length of hospitalization. Randomized trials are still needed to demonstrate its efficacy.

[Management of necrotizing cellulitis and fasciitis]. / Quelle prise en charge pour les cellulites et fasciites nécrosantes?

A literature review did not reveal any controlled study on the management of necrotizing fasciitis. Treatment protocol includes: - an immediate or early surgical management with debridement of all necrotic tissue and extensive fasciotomy followed by a surgical reexamination of the infected area in the following days; - an initial antibiotic therapy targeting aerobic Gram-positive and Gram-negative organisms and anaerobes (e.g: amoxicilline-clavulanic acid or vancomycin-metronidazole); - an adequate nutritional support, infusion, and resuscitation; - hyperbaric oxygen therapy may be considered as an associated treatment; but there is no randomized, controlled trial demonstrating its efficacy.
