RESUMEN
BACKGROUND Gas gangrene is a rapidly progressive and potentially fatal infection that is common in the extremities. Gas gangrene of the head and neck is a very rare condition, and non-clostridial gas-forming neck abscess caused by Klebsiella pneumoniae is unusual. This report is of a diabetic man with poor dental hygiene, a right dental abscess, and parapharyngeal abscess with gas gangrene due to Klebsiella pneumoniae infection, presenting with septic shock and multiorgan failure, who recovered after surgical neck debridement. CASE REPORT A 52-year-old man with diabetes mellitus lost consciousness and collapsed on a curbside. He presented with painful swelling of the right-side neck, associated with spiking fever, confusion, dyspnea, and stridor. He had right submandibular and supraclavicular swelling with crepitus, multiple dental caries, and multiorgan dysfunction, and was intubated. A computed tomography scan showed a gas-forming abscess in the right parapharyngeal, retropharyngeal, and paralaryngeal spaces and dense infiltration with pleural effusion in the upper lobes. Neck exploration was performed for drainage. Necrotic tissue and foul-smelling pus were debrided and drained. Gram stain showed gram-negative bacilli. Necrotic tissue, pus, and blood culture showed Klebsiella pneumoniae. He remained on intravenous meropenem for 14 days and was frequently debrided with irrigation until the infection subsided. Finally, normal physiologic functions of the failing organ system were restored. CONCLUSIONS We present a rare case of Klebsiella pneumoniae infection causing gas gangrene in the deep neck spaces, leading to septic shock and multiorgan failure, who recovered after surgical neck debridement. This is a potentially fatal condition that requires emergency drainage because of its high mortality rate.

We present the case of a 57-year-old male patient with a fatal outcome after resection of a soft tissue sarcoma of the lateral thigh. A polymicrobial surgical site infection with Staphylococcus lugdunensis and Clostridium perfringens caused fulminant necrotising fasciitis with an additional gas gangrene. The patient suffered a severe sepsis with consecutive haemolysis and multiorgan failure. The authors recapitulate the deadly progress of a rarely reported complication after oncological resection. The therapeutic approach and surgical interventions are discussed based on the current literature.

ABSTRACT: Post-traumatic gas gangrene is a rare but potentially life-threa-tening condition due to soft tissues infection by Clostridium species. These anaerobic microaerophile bacteria are highly resistant to external insults related to their ability to produce spores, which can survive on any surface for long periods. Under certain conditions suitable for proliferation (such as in ischemic tissues), bacteria produce many to-xins. In particular, Clostridium perfringens type A represents the most frequent cause of traumatic gas gangrene nowadays. It produces toxins responsible for thrombotic and necrotic phenomena in soft tissues and rapid disease diffusion to muscles. Clinical manifestations usually start as local edema and emphysema but rapidly evolve into a septic state. Prognosis is poor in 20-30% of cases, and death occurs due to multiorgan failure. Because of its rapid evolution, clinical diagnosis is not always obtained, thus determining the need for post-mortem investigation. This case report presents a rare case of fulminant gas gangrene due to Clostridium Perfrigens infection developed after trau-matic injury. Despite the prompt antibiotic administration and surgical intervention on the site of trauma, gas gangrene rapidly evolved into septic shock, leading to the patient's death. Post-mortem investigations were conducted and confirmed multiorgan failure as the cause of death. Cultural analysis was also performed but showed no bacterial growth. Negativity on culture tests should be related to antibiotic administration before blood sampling and bacterial characteristics. In such cases, the correct identification of the cause of death was only possible following a careful and detailed forensic methodological approach.

Necrotising infections remain challenging to surgeons, both in diagnosis and management. Timely recognition and treatment remain vital. We report a presentation of limb ischaemia with no apparent precipitating factors, in a systemically stable patient, due to atraumatic Clostridium septicum myonecrosis. This article demonstrates the use of rapid cross-sectional imaging in finding an undiagnosed bowel cancer as a basis for this type of infection. Rapid cross-sectional imaging may be utilised where there is doubt about the underlying pathology of upper limb ischaemia. Patients whose cultures grow Clostridium septicum must be investigated for malignancy.

INTRODUCTION: Abdominal gas gangrene caused by Clostridium perfringens is a rare differential diagnosis to pneumoperitoneum caused by bowel perforation. There are only a handful of case reports on this topic. PATIENTS AND METHODS: We present the case of a 58 year old cirrhotic patient who represented to our ER after complicated surgery for retroperitoneal liposarcoma. On admission he complained of abdominal pain and mild fever. Due to leukocytosis and CRP a CT scan was performed which showed extensive free air. The patient was taken to the OR for suspected bowel perforation. No perforation could be identified after extensive search and lavage. RESULTS: Twelve hours after surgery microbiology reported extensive growth of clostridium perfringens in the cultures drawn from ascites. The patient was successfully treated with antibiotics and discharged home soon after. CONCLUSION: Gas gangrene is a rare differential diagnosis to bowel perforation. Most reported cases are from cirrhotic patients. If no perforation can be identified in the OR postoperative antibiotics should cover clostridium perfringens.

Clostridial myonecrosis is a medical and surgical emergency which requires early and aggressive intervention to reduce mortality. We report a rare case of Clostridium septicum myonecrosis that disseminated hematogenously from a gastric perforation. The patient was afebrile and hemodynamically stable upon admission. He rapidly developed spontaneous clostridial myonecrosis and succumbed to septic shock 36 hours after presentation. In our extensive literature review this is the only case with blood cultures confirming Clostridium septicum bacteremia with a surgically confirmed gastric perforation source in the setting of spontaneous clostridial myonecrosis.

Gas gangrene is a rare and potentially fatal surgical complication, most often associated with contaminated traumatic wounds or more rarely following cases of abdominal surgery. The following article describes a case of gas gangrene in the right lower limb of a 34-year-old patient following an elective posterior tibial tendon transfer. The surgery was performed in bloodless fashion, utilizing a surgical tourniquet. Fifteen months prior to the procedure, the patient was attacked by a wild boar, resulting in a tear of the upper calf with complete transection of the right common fibular nerve. The patient underwent a total of three acute surgical procedures, of which the third resulted in below knee amputation. The patient then underwent a final corrective procedure and was fitted with a suitable leg prosthesis. In the discussion, three possible pathophysiological mechanisms of gas gangrene development are described - iatrogenic inoculation of bacteria during injection of local anesthetics for conduction anesthesia, iatrogenic inoculation of bacteria during the posterior tibial tendon transfer and activation of latent clostridial spores within the original wound caused by the wild boar. We consider the third mechanism most likely, as boar tusks contaminated with soil and debris are a more likely source of clostridial spores, than sterile surgical instruments. Furthermore, it is likely the surgical tourniquet played a key role in activating latent spores within the patient wound, as changes in tissue oxygen levels are a common cause of spore activation. Thus, we suggest caution in utilizing bloodless operating fields in elective cases with a history of open contaminated wounds, as the iatrogenic hypoxia can potentially activate sporulent bacteria within the patients wound.

BACKGROUND Clostridial myonecrosis, also known as gas gangrene, is a highly lethal necrotizing soft tissue infection. While commonly associated with trauma, clostridial myonecrosis may be the result of parenteral injection of medications. Epinephrine is the most commonly reported medication leading to gas gangrene. CASE REPORT A 60-year-old man presented to the Emergency Department (ED) with "the worst pain in his life" to the right thigh near the site at which he auto-injected epinephrine after multiple bee stings 10-11 h prior to arrival. Initial heart rate was 112 beats/min but all other vital signs were unremarkable at presentation. Due to extreme pain, a computed tomography (CT) scan was ordered, revealing prominent gas within the anterior compartment of the right thigh, mostly involving the vastus lateralis and rectus femoris, suggesting necrotizing fasciitis. Antimicrobials were initiated immediately and the patient was taken for surgical debridement within 70 min after obtaining the CT results. Clostridium perfringens was cultured from the patient's tissue. After several surgical debridement's, appropriate antimicrobial therapy, supportive care, and wound care, the patient's limb remained intact and he was discharged after 11 days. CONCLUSIONS With millions of epinephrine auto-injectors prescribed yearly in the United States, awareness of clostridial gas gangrene following epinephrine auto-injection for the provider may help guide decision-making in patients presenting with extreme pain, redness, or swelling near the injection site after epinephrine injection.

BACKGROUND: Colonoscopy is a routine procedure in diagnosis and treatment of colonic disease. While generally regarded as a safe procedure, potentially fatal complications can occur. Gas gangrene is one such complication, with very high mortality. There are few cases of gas gangrene occurring after colonoscopy, making it one of the rarer complications of this procedure. There have been no previously reported cases of a patient surviving such an infection and the optimal treatment strategy is contentious. This report describes a case of intramural gas gangrene of the colon, treated conservatively with antibiotic therapy in which the patient survived with full recovery. CASE PRESENTATION: A 71-year-old, previously healthy male presented 6 h post apparently uncomplicated colonoscopic polypectomy with rigors, nausea, vomiting and right upper quadrant pain. At presentation he was febrile at 40.1 °C but hemodynamically stable. Abdominal computed tomography revealed substantial colonic thickening and several focal intramural gas bubbles (pneumatosis intestinalis) surrounding the polypectomy site. Within 24 h post procedure he became hypotensive and was admitted to ICU in frank septic shock requiring inotropes, and with demonstrable septic myocardial depression. Bloods showed multi-organ derangement with leukocytosis, lactic acidosis, haemolytic anaemia and hyperbilirubinemia. A diagnosis of presumed Clostridial gas gangrene was made, and treatment was initiated with benzylpenicillin, clindamycin, metronidazole and vancomycin. After 4 days in ICU he was stepped down, and discharged after a further 10 days with no surgical or endoscopic interventions. At three-month review he reported being back to full health. CONCLUSIONS: This case demonstrates that gas gangrene infection is a possible complication of colonoscopic polypectomy. This is a cause of rapid deterioration in post-colonoscopy patients and has been misdiagnosed as colonic perforation in previously reported cases of retroperitoneal gas gangrene. Such misdiagnosis delays antibiotic therapy, which likely plays a role in the high mortality of this condition. Early diagnosis and initiation of antibiotic therapy with benzylpenicillin and clindamycin as seen in this case is essential for patient survival. While surgery is typically performed, non-operative management of pneumatosis intestinalis, and potentially gas gangrene is becoming more common and was utilized effectively in this patient.

Streptococcus anginosus (SAG) is a known human pathogen and member of the Streptococcus milleri group. SAG is a known bacterial cause of soft-tissue abscesses and bacteremia and is an increasingly prevalent pathogen in infections in patients with cystic fibrosis. We describe a rare case of SAG as an infectious agent in a case of nonclostridial myonecrosis with soft-tissue emphysema. This is the only case found in the literature of SAG cultured as a pure isolate in this type of infection and was associated with a prolonged course of treatment in an otherwise healthy patient.

Clostridium perfringens type A causes gas gangrene characterized by myonecrosis and development of an effective therapy for treating affected patients is of clinical importance. It was recently reported that the expression of granulocyte colony-stimulating factor (G-CSF) is greatly up-regulated by C. perfringens infection. However, the role of G-CSF in C. perfringens-mediated myonecrosis is still unclear. Here, we assessed the destructive changes in C. perfringens-infected skeletal muscles and tested whether inhibition of G-CSF receptor (G-CSFR) signaling or administration of recombinant G-CSF affects the tissue injury. Severe edema, contraction of muscle fiber diameter, and increased plasma creatine kinase activity were observed in mice intramuscularly injected with C. perfringens type A, and the destructive changes were α-toxin-dependent, indicating that infection induces the destruction of skeletal muscle in an α-toxin-dependent manner. G-CSF plays important roles in the protection of tissue against damage and in the regeneration of injured tissue. However, administration of a neutralizing antibody against G-CSFR had no profound impact on the destructive changes to skeletal muscle. Moreover, administration of recombinant human G-CSF, filgrastim, imparted no inhibitory effect against the destructive changes caused by C. perfringens. Together, these results indicate that G-CSF is not beneficial for treating C. perfringens α-toxin-mediated myonecrosis, but highlight the importance of revealing the mechanism by which C. perfringens negates the protective effects of G-CSF in skeletal muscle.

BACKGROUND: Clostridium perfringens can cause various infections, including food poisoning, gas gangrene, cellulitis and fasciitis. C. perfringens septicemia is rare, but is a known cause of hemolysis by damaging red blood cell, and often proves rapidly fatal in emergency department (ED) situations. CASE PRESENTATION: A previously healthy 76-year-old man presented to the ED 8 h after onset of acute abdominal pain and diarrhea. Laboratory examination revealed a large discrepancy between the red blood cell count of 1.91 × 106/mm3 and the hemoglobin level of 10.3 g/dL, suggesting massive intravascular hemolysis. Computed tomography revealed liver abscesses with gas. During ED treatment, the state of the patient rapidly deteriorated and he entered cardiopulmonary arrest. Blood cultures finally identified C. perfringens. CONCLUSION: Intravascular hemolysis and red blood cell (RBC) / hemoglobin (Hb) discrepancy in the presence of infection should prompt ED physicians to consider C. perfringens septicemia and to act quickly to provide appropriate treatment.

Gas gangrene, or clostridial myonecrosis, is usually caused by Clostridium perfringens and may occur spontaneously in association with diabetes mellitus, peripheral vascular disease, or some malignancies but more often after contamination of a deep surgical or traumatic lesion. If not controlled, clostridial myonecrosis results in multiorgan failure, shock, and death, but very little is known about the muscle regeneration process that follows myonecrosis when the infection is controlled. In this study, we characterized the muscle regeneration process after myonecrosis caused in a murine experimental infection with a sublethal inoculum of C. perfringens vegetative cells. The results show that myonecrosis occurs concomitantly with significant vascular injury, which limits the migration of inflammatory cells. A significant increase in cytokines that promote inflammation explains the presence of an inflammatory infiltrate; however, impaired interferon gamma (IFN-γ) expression, a reduced number of M1 macrophages, deficient phagocytic activity, and a prolongation of the permanence of inflammatory cells lead to deficient muscle regeneration. The expression of transforming growth factor ß1 (TGF-ß1) agrees with the consequent accumulation of collagen in the muscle, i.e., fibrosis observed 30 days after infection. These results provide new information on the pathogenesis of gas gangrene caused by C. perfringens, shed light on the basis of the deficient muscle regenerative activity, and may open new perspectives for the development of novel therapies for patients suffering from this disease.
